Method and device for repairing damaged wooden pallets

0001The invention relates to a method and apparatus for repairing damaged wooden pallets, in particular Euro pallets.

0002From DE 44 35 574 C1 discloses a device for partial or complete dismantling of defective known wooden pallets. With this apparatus it is possible damaged skids or deck boards of Wooden pallets, in particular Euro pallets automatically separate. The damaged skids or deck boards are separated by the Euro pallets through a Knife system are printed. Here are nails, with which the deck boards or runners are nailed, severed. The device according to the prior art restricted to the pure separation of the damaged Parts. As the separated, damaged parts by replaced new, intact parts and the pallet so can be fully repaired, remains open.

0003The present invention is based on the problem to provide a method and an apparatus, by the damaged wooden pallets largely automatic can be repaired.

0004To solve this problem, the present invention Method, the process steps of claim 1 and the Inventive device training features according to claim 10.

0005According to the invention initially predetermined, damaged Boards and / or runners separated. This can For example, with a device according to DE 44 35 574 C1 done. After the separated boards discharged and / or skids from the workspace have been, the separated boards and / or Runners replaced with new boards and / or runners. At the same time or in a separate operation the newly added parts aligned. This can either be done by the partially dismantled Palette is the correct position fitted with new parts. Alternatively, the new parts can also roughly positioned placed on the partially disassembled pallet and then positioned in a separate station will. Finally, the newly added parts are nailed the part disassembled pallet. The plate is now completely repaired.

0006It is particularly advantageous when separated, damaged skids in a separate operation repaired and then re defective for repair Pallets are used. When the pallet repair the result is minimal waste which must be disposed of. After the runners repair these can a runners magazine are fed from the skid for mounting the partly dismantled pallets are removed.

0007According to a development of the invention, the damaged pallets fed batch and then separated. They can then a Survey course be supplied in the visually found damage to the pallet to be repaired will. This may be by an operator or automatically by a surveillance camera and corresponding image recognition systems or other Range control devices happen. Should such Assessment undamaged pallets or too strong detected damaged pallets, it is expedient to these diverted out the repair process. Idlers in the System are avoided. In addition to heavily damaged pallets possibly interfere in repair system lead. Of course, the System are also set so that undamaged Pallets worked through the repair facility.

0008After the pallets partly dismantled so damaged Parts have been separated off, it is advantageous to first cache in a pallet buffer. This allows a disassembly area and a Mounting area for the pallet repair each other be separated, so that in case of faults one of the areas that can each other continue.

0009When cutting off the damaged parts of it can happen get that wood splinters on the part dismantled pallet remain or nails not fully severed, but the damaged parts only these are deducted. This may result in the newly added skids and / or boards completely abut the part disassembled pallet. According to a development of the invention is therefore proposed that the newly added parts to the to press nailing. The newly added components are then completely on.

0010After the repair, it is advantageous to the pallets stack and in a magazine for removal provide.

0011Further features of the invention relate to itself Embodiments of the individual stations to carry of the method or the invention Device of the invention.

0013Euro pallets 10 wood have nine, in three longitudinal and Transverse rows arranged blocks on 11th Longitudinal is among three of the blocks of a number a Floorboard 12 nailed. Overall, therefore, are three Floorboards 12 available. In the transverse direction to the Blocks 11, ie on the floorboards 12 opposite sides of the blocks 11, 13 cross boards arranged. The cross-boards 13 are in turn on three of the blocks on 11th On the cross boards 13 again lie longitudinally five Deck boards 14. The two outer deck boards 14 and the middle deck board 14 lie above the Floor planks 12 to the cross-planks 13. The Transversal boards 13 along with this deck boards 14 nailed to the wood of the 11th The other two, something narrower deck boards 14 are only at the Cross boards 13 nailed.

0014Through the use of the Euro pallet 10, it often to the fact that individual blocks 11 or individual boards 12,13,14 be damaged. The damaged pallets are then generally by exchanging the corresponding parts repaired. A system for a Such automatic pallet repair is shown in Fig. 1 shown in more detail.

0015To be repaired pallets 10 are in stacks on a feed conveyor 15, for example by means of a Forklift, deposed. The feed conveyor 15 is formed the present case as a chain conveyor and comprises three plots 16 for stacks of to repaired pallets 10. By the induction conveyor 15 the pallet stack isolated in a Unstacker 17th For this purpose, a complete stack of pallets 10 in the Unstacker 17 promoted. Subsequently, the Pallet stack by a bottom in the stack engaging lifting table to the final position of the Lift table lifting cylinder lifted. When draining of the stack engage laterally at a specific position four holders in the second lowermost pallet from below, so that these in further lowering of the stack on the Holders rests. The lowermost pallet 10 is further lowered until it rests on a conveyor. she will here held by a stopper in place. Once the stopper is released, the range is 10 17 conveyed out of the range of denester. Now moves the lifting table again until its final position high and raises the remaining stack of pallets 10 from the holders out. The holder fold then returned and the stack is lowered again. The holder access now again in the now second-bottom position pallet located 10 from below. The lowest Pallet 10 is lowered again on the conveyor and can be conveyed out. This process repeats until that the entire stack of pallets 10 is isolated. Now, a new pallet stack in the are conveyed Unstacker 17th

0016As an alternative to the four, in the pallet stack retractable holders is also following construction possible. are on both longitudinal sides of the pallet stack at the level of the second lowest pallet 10 per a Stringers arranged. These stringers are of a remote from the second from bottom pallet 10 Basic position to an engaged position immediately adjacent the second from bottom pallet 10 is movable, preferably pivotally. At each of the two support bars are six spring-loaded retaining pins arranged. During the movement the stringers in the holding position engage these Retaining bolts depending on the positioning of the range under the outer cross boards 13 and deck boards 14 of Palette 10. Triggers one or more of the spring-loaded Retaining bolt against an Klotz 11 they are against the spring load is pushed into the supporting beam. Concrete the retaining bolt are arranged so that in each case the two outer retaining pin positioned in correctly Blocks 11 abut the corners of the pallet against this and be pushed back. If one or more of 11 pads 10 but shifted to the corners of the pallet, keep this palette and another retaining bolt optionally pushed back. Thereby, the Palettenstapel always ensure sufficient on a Number worn by retaining bolts so that a risk of Overthrow of the pallet stack does not exist.

0017At a frame for the de-stacker 17 are two pneumatically driven flaps attached. These also prevent that the pallet stack, which is just the de-stacker 17, tip over. After this the last pallet 10 of the previous stack from the Range of denester 17 has been fed out, two flaps are opened by means of pneumatic cylinders. A new pallet stack can now in the destacker 17 are conveyed into. The valves close simultaneously with the stroke of the lifting table. The stack is now secured against tipping. Sensors show the opened state on the flap. This is prevents a new pallet stack up closed holes travels.

0018Following the de-stacker 17 to reach the repaired pallets on an intermediate space 18. In Area of ​​this intermediate space 18 is located at a Carriage movable saw. This can greatly damaged and protruding from the pallet 10 or collapsed portions of the boards 12, 13 or 14 be severed and removed manually. This will Disturbances in the downstream components is avoided.

0019The pallet 10 now enters a verification station 19. In the illustrated embodiment is here by a established operator 20, which parts of the pallet 10 damaged. This is in a control panel 21 input, which via a PLC control the subsequent conditioning controls. Alternatively, here the detects damage even by a camera system and means an automatic image processing or by a Another range tachograph data on the damaged Parts are fed into the PLC.

0020Where, in the review station 19 that accidentally completely intact pallet 10 or too badly damaged pallet is present 10, this also detected accordingly. These pallets can now access a subsequent range switch 22, in be Fig. 1 to the left, discharged. Of the Pallet diverter 22 are further pallet 23 points downstream, on which the completely intact from the "Scrap" pallets isolated and on separate lines 24, 25 and 26 are provided sorted. in the the present case, the lines 24 and 25 yet Pallet stacker 27 through which the separated Pallets 10 are put back together into stacks can.

0021Damaged to be repaired pallets 10 are of the Palette Soft 22 conveyed to a handover 28th, respectively. The pallets 10 are here by means of a molded part in the subsequent disassembly station 29 inserted. The DismantleStation can substantially in DE 44 35 574 C1 device described match. here are the damaged pallets 10 selectively dismantled. Concrete Predetermined deck boards 14 and / or predetermined, each consisting of a bottom board 12 and for this Floorboard 12 belonging three blocks 11 formed skids 30 separated. The separated deck boards 14 and / or Skid 30 pass through a chute or channel on a Belt conveyors 31 and are from this side conveyed away.

0022By disassembling conveyor 32 are the partly dismantled pallets 10 of the disassembly station 29 conveyed away. The dismantling conveyor 32 is a two-row chain conveyor with a plurality, in a Distance of about 1.85 meters arranged flights. From the dismantling conveyor 32 are the partly dismantled Pallets 10 conveyed to a pallet magazine 33rd Here Several partly dismantled pallets 10 are cached.

0023the partially dismantled are from the pallet magazine 33 Pallet 10 is removed and a loading station 34 supplied. The loading station has an average Transfer station 35 and - in this case the left of it - a skid assembly station 36 and the right of Transfer station 35, a board loading station 37. In the sled assembly station 36, if necessary separated skids 30 by new or repaired skids 30 replaced. In a corresponding manner, in the Board assembly station 37 separated deck boards 14 replaced by new ones. The exact way in which Sled assembly station 36 and the Board assembly station 37 are further below explained in more detail.

0024The extent completed pallet 10 is now a Centering and nailing station 38 supplied. In the centering and Nailing station 38, the newly added 14 boards and / or skids 30 is centered, that is, exactly at the partially disassembled pallet 10 positioned. The replaced Deck boards 14 and / or skids 30 are automatically placed in the intended position. Pallet 10 stops here and can be nailed manually. alternative can also be an automatic nailing. To this end, can the centering and nailing station 38 a bridge 39 crosswise with a traveling shot camera or five, each deck board placed 14 associated shot cameras be. Alternatively, all of which can, to a cross-board 13 belonging nails are driven simultaneously. Located at the range 10 with their first cross board 13 under the bridge 39, are selectively replaced Deck boards 14 and / or nailed runners 30th The plate 10 will now be conveyed further until the second Cross Board 13 is under the bridge. 39 here are the necessary Nailings performed. thereupon the process is repeated for the third Cross Board. 13

0025From the centering and nailing station 38 reach the nailed pallets 10 in a pressing station 40. In the Pressing station 40 may be protruding nails and not quite fitting boards 12, 13, 14 or skids 30 pressed after nailing. For this purpose, in the field of transversal boards 13 five individual pneumatic cylinders arranged that compress the pallet 10th To the Piston rods of pneumatic cylinders are five arranged alloy wheels which is lowered onto the pallet 10 will. By a light barrier, the presence a cross-board 13 under the metal wheels sensed. The Pneumatic cylinders are then compressed air applied and so the alloy wheels on the pallet pressed. Once the cross board 13 from the area of Photocell is driven out and so the light barrier has been released, the Pneumatic cylinder with a follow-up time of 0,2 seconds depressurized.

002610 From the pressing station 40 enter the pallets in a Eckensägestation 41. This serves to mesh hat side deck boards 14, 11 blocks and floor boards 12 of the pallet 10. The pallets 10 are thus in Top view chamfered at their vertical edges. in the Following the Eckensägestation 41 is a Burning station 42. Here are emblems, such as The DIN symbol, burned in some of the blocks 11th

0027The extent completed repaired pallet 10 now has more a control station to go through 43 before they two successively arranged palette switches to two be distributed discharge conveyor 45th In the area of ​​the discharge conveyors 45 are respectively a pallet stocker 46 through the 10 to pallet stacks the individual pallets back are summarized. These are present on the Case three deployment places 47 per Discharge conveyor 45 provided for transport.

0028Furthermore, in FIG. 1 is still a runner repair station 48 recognizable. This includes a sled repair station 49 and a runners magazine 50. It can be seen in Fig. 1 that by the belt conveyor 41 the separated parts parallel to Runners repair station 48 in an area adjacent to be encouraged runners repair place 49th A operator can here pick out damaged skids and repair at the repair station skids 49th The repaired Runners are the operator then in the magazine runners 50, by which it skids for loading station 36 promote and exchange Severed skids 30 to be provided.

0029The individual stations of the extent roughly described System are described in more detail below.

0030In FIGS. 2 and 3, the skid assembly station 36 with the runners of loading station 36 associated end of the shown skids magazine 50 in detail. The runners magazine 50 has three superposed skid conveyors 51,52 and 53 on. Each skid conveyor 51..53 is a position the runners 30 associated with the pallet 10th In the upper Skid conveyor 51 thus are the runners 30 of the leftmost position on the pallet 10, in the middle Conveyor 52 the runners 30 of the middle position and in lowermost conveyor 53 the skids right position as shown in Figure 2.. are in runners Magazine 50 always new or used, repaired skids 30 in sufficient numbers.

0031The individual runners conveyor 51..53 are as Chain conveyor formed by two adjacent arranged conveyor chains 54. runs of the chains 54 are deflected over deflection wheels 55 downwards. The Conveyor chains 54 are here by about driving pinion an electric motor 56 is driven.

0032The skid conveyor 51 each extend into the region a discharge channel 57. The runners 30 are here on a Ejection means 58 postponed. This is shown in Fig. 3 closer to detect. The on the upper run of the conveyor chain 54 dormant and centered by guide skids 59 30 be of the skid conveyor 51..53 a discharge claw 61 stored. Between an upper leg 60 and a lower leg 62 of the discharge claw 61 is the next scheduled for pallet repair skid 30th The release claws 61 are hinged by a hinge 63 stored and via a lever 64 by means of a Pneumatic cylinder 65 tilted. By extending the Pneumatic cylinder 65, the lower leg 62 by outwardly pivoted and free the skid 30th additionally the runner 30 through the upper leg 60 forcibly pressed downward. This now falls through the Discharge channel 57 down and lies for too repaired pallet 10 ready. The pneumatic cylinder 65 are now fully retracted so that the upper Legs are pivoted 60 to the outside. Then, the next runner 30 fed from the conveyor runners and 51..53 Registered been promoting on the lower leg 62nd Of the lower leg 60 for this purpose has at its free End side rollers 95 on. The entire process is carried monitors light barriers, the correct positioning Show the skids 30th This prevents that one in the discharge channel 57 falling downward skid 30 by subsequent skids 30 is hindered.

0033The board assembly station 37 is shown in FIGS. 4 and 5 shown in more detail. The board mounting station 37 serves as specifically, for automatically replacing the separated or lack of deck boards 14. The board loading station 37 for this purpose has several, namely five, Board Magazine 66 on. The Board Magazine 66 hold about twenty to forty Boards, depending on the version. They are respectively above the corresponding board position in the longitudinal direction arranged. Each board magazine 66 is in linear guides 67 by means of holders 68 and 30 millimeters vertically mounted. For this purpose, any Board magazine 66 associated with a pneumatic cylinder 69th Becomes for the repair of a pallet 10 within the Board assembly station 37, a cover board 14 requested, is the board magazine 66 for the corresponding Brett position lowered. The pallet 10 will now be completely pushed under the magazine and the lowest deck board 14 in the board magazine 66 by a Entrainment on chain conveyor for pallet 10 from the Board magazine 66 taken and so in the correct position stored on the pallet 10th The exhibit Brett Magazine 66 at its lower end to that end inwardly directed legs 70, on which the deck board 14 rests. On its face, the Board Magazine 66 open and at the bottom also have a recess 71, through which the driver of the chain conveyor for the repair range can drive through 10th

0034After the deck board and deck boards 14 on the Pallet 10 have been stored, so from the respective Brett magazines have been 66 expelled, the Brett lowered Magazine 66 back into its Starting position raised. A suitable sensor monitors whether constantly a sufficient number of new Deck boards 14 is present in the board magazine 66th Becomes a predetermined minimum number below, is the sensor given an audible or visual signal, so that an operator the respective board magazine 66 can replenish.

0035In an analogous manner to the board mounting station 37 for Deck boards 14 may also be a loading station for be formed transversal boards. 13 This would merely 90 ° relative to the sled assembly station 36 and Board assembly station 37 between these two Stations located. A loading station for Transversal boards 13 would initially the cross-boards 13 to Skids 30, namely the pads 11, stored and then the Deck boards 14 are placed. These are then on the Conveyor chain of the chain conveyor corresponding driver mounted, the cross-boards 13 corresponding to the remove items from the magazine. With the installation new pallets can thus be produced.

0036In Figs. 6 and 7, the centering station to the exact Positioning of the superseded runners 30 and deck boards 14 shown in more detail. Through the same chain conveyor whose two conveyor chains 72 in FIG. 6 can be identified, with the the repair pallet 10 already by the other Stations has been promoted 35,36 and 37, the Pallet inserted into the centering station. The runners 30 the pallet 10 pass through insertion channels 73 in Zentrierkanäle 74, 75 and 76. The right centering channel 76 has a fixed outer wall 77 and a movable Inner wall 78. By means of spring-loaded plunger 79 is the movable inner wall 78 pressed outward and so the skid 30 against the stationary outer wall 77 positioned.

0037The middle centering channel 75 has two movable walls 80, according to the above also spring-loaded plunger 81 inside are pressed. The spring forces are so designed such that the middle blade 30 relative to the fixed, right outer wall 77 is positioned exactly.

0038The left centering channel 74 has a movable Inner wall 96 analogous to the movable inner wall 78 of the right channel 76. The movable inner wall 96 of the Zentrierkanals 74 is also spring loaded by Ram 79 loaded. Furthermore, the centering channel 74 a movable outer wall 97, which by spring-loaded plunger 98 to the right in the direction of the solid outer wall is pressed 77th The movable Outer wall 97 is formed higher than a pallet 10th This takes the whole pallet 10 together with its left runner 30 in the direction of the fixed exterior wall 77 pressed and so precisely positioned.

0039Through an analog device, the deck boards are 14 also positioned. The now properly aligned Pallet 10 can within the centering and nailing station 38 nailed in the manner described above.

0040Referring to FIG. 8 to 10 will be the runners repair station 49 described in detail. In the skids repair station 49 will be the runners 30 with the pads 11 down inserted. Through each one hydraulically operable terminal 82, which cooperates with a fixed jaw 99, the pads are each 11 clamped, the are undamaged and thus be further used can. A damaged and thus auszuwechselnder Klotz 11 is not clamped, so that it after the separation fall downward from the runners repair station 49 can.

0041The terminal 82 is connected to guide rods 83 in a Linear guide 84 mounted. By means of a piston rod 85 , the respective clamp 82 closed right will. The floor board 12 is fixed by clamps 100, likewise with the fixed jaw 99 as a counter-organ cooperate. To disconnect individual blocks 11 or all blocks 11, so the floorboard 12, will now the separated block 11 associated blade systems 86 analogous to those described in DE 44 35 574 C1 Knife systems folded down. This is done by an actuating cylinder 87, the respective the Knife assembly 86 about a joint 88 folds downwards. A Piston rod 89 of the actuating cylinder 87 is for this Purpose articulated at 90 on the blade system 86th

0042The entire clamping device with the terminals 21 and 100 and the jaws 99 can be moved on a carriage 91 stored. The carriage 91 has to be for this purpose both sides outwardly open U-profiles 101 which run on rollers 102nd Each side of the carriage 91, each U-shaped profiles 101 are two rollers 102 assigned by the in FIG. 8, only the fasteners 103 are visible.

0043The two U-profiles 101 of the carriage 91 are by a crosspiece 104 joined together. At the Crosspiece engages a piston rod of a Hydraulic cylinder 92 on which at its other end a crossbar 105, which is also the knife systems 86 is wearing, attached. The crossbar 105 is fixed to a frame 106 of the runners repair space 49 connected. The hydraulic cylinder 92 now pushes the Slide 91 according to the illustrations according to FIGS. 8 and 9 the right so that the clamped blade 30 through the fixed blade systems is pushed 86th

0044A slightly vertically movable to spring plungers 93 Upper guide 94 slides during the separation process over the floorboard 12 and thus provides the necessary height for an actual blade 107 (Fig. 9). By further stroke of the hydraulic cylinder 92 reaches the knife 107 between the floorboard 12 and the block 11 and cuts through the nails by which the two parts are nailed. The respective blade system 86 is then moved back to the starting position and the terminals 82 dissolved. Depending on the damage can now the floorboard 12 or the or the respective blocks 11 and exchanged the skid 30 are then nailed.

0045The jaws 99 each have a horizontal slot in height of the blade 107. The carriage 91 can thus proceed always far enough to a 11 to ensure complete removal of the pads. The blades 107 drive it into the slots of the jaws 99th

0046It should be noted at this point that only folded down the knife system 86 at the position is where a runner is 30 separate. For example, only the floorboard 12 damaged in a skid 30, Only 3 blocks 11 clamped and all three Knife systems 86 folded down. The board is now of the blocks by moving the slide 91 by means of Cylinder 92 can then be separated and for example, by an operator or automatically be removed. After fitting a new floorboard 12, the runner 30 is nailed. If, however, For example, only the central block 11 damage, only the two outer blocks 11 are clamped and only the middle blade system 86 folded down. The middle block 11 will now be from the floorboard 12 in the separated manner described above and falls below from the runners repair station 89 out. Substituting a new pad 11 is in turn nailed. Finally, if for example, the floorboard 12 and right Klotz damaged 11, the left and the middle block 11 clamped and all three Knife systems 86 folded down. The floorboard 12 is now in the manner described above from all three blocks 11 separated, the damaged, right Klotz 11 falls down from the sled repair place 49th The damaged block 11 and the floorboard 12 are now replaced and the blade 30 nailed again.

0047It is further noted that, alternatively, also the Knife systems 86 can be moved, while the Skids 30 resting.

0048The repaired blade 30 is then by an operator in the left hand above the skids repair space 49 Runners magazine 50 inserted. The same operator can assemble the runners magazine with new runners.

0049The station with the pallet magazine 33 is shown in Figs. 11 to 13 shown in more detail. The pallet magazine 33 has arranged in each case two on either side of a pallet Conveyor chains 108. Each of the half of its length, So on the length of a strand, the conveyor chains are 108 equipped with holders 109, on which the pallets 10 in the Pallet magazine 33 rest. Specifically, under the grip holder 109 located respectively on the end faces Transversal boards 13. The holders 109 are respectively connected to each second link 110 of a run of the conveyor chains 108 mounted, as shown in FIG. 13 is particularly clearly visible. The conveyor chains 108 are each circumferentially on upright Posts 111 mounted on the chain sprockets 112 of the lower sprocket 112 are each driven. there are two of the sprocket 112 on a arranged common axis, the driven Axes are driven by a common drive. Specifically, a chain drive is provided with Trumumkehr, so that each disposed opposite each other Conveyor chains 108 are driven in opposite directions.

0050The cached, pallets 10 are below inserted into the pallet magazine 33rd The pallets 10 be the dismantling conveyor 32 under the Pallet magazine 33 promoted. Through a lifting table 113 is the respective pallet 10 from the dismantling conveyor 32 lifted and in an area just below the Pallet magazine 33, namely approximately at the level of lower sprocket 112 of the conveyor chains 108 raised. The conveyor chains 108 are now in opposite directions so driven to a Cold 109 per conveyor chain 108 Range 10, specifically the cross board engages under 13 and apart from the lift table 113th The lift table 113 now moves back to its lower position and is to take over a subsequent pallet 10 ready.

0051Runs the entire range Repair System operational, the pallets 10 but directly from the Dismantling conveyor 32 in the loading station 34 to hand over. To this end, located on one level beneath the pallet magazine 33 and above the Dismantling conveyor 32 a transfer station 114. The Lift table 113 is now taking over from the dismantling conveyor 32 the pallets 10 and she lifts only up to the level the transfer station 114. In the transfer station 114 is an unspecified recognizable and across the The transport direction of the conveyor disassembly 32 Portable Carriage. The slide has at both end sides of the Range displaceable in a horizontal plane Holding beam on, are attached to the cold, the Range 10, specifically the outer cross-boards 13 under attack. These are to take over the range 10 moved together and the carriage then in the Representation according to FIG. 1 down in the Loading station 32, namely the transfer station 35 process. Here the range 10 of the carriage is on issued a further chain conveyor pallets 10 through subsequent stations of FIG. 1 transported.

0052In an analogous manner, with the aid of the lifting table 113 also pallets 10 removed from the pallet magazine 33 and be lowered to the level of the transfer station 114, where they in turn described by the above over carriage and the transfer station 35 be transported.

0053Another feature of the above Pallet transfer is that here again is detected, which skids 30 and deck boards 14 in the Disassembly station 29 have been separated. Concretely the area of ​​each runner position an optoelectric Sensor to the horizontally movable support beam of Carriage mounted. This works with a mirror in opposite support beam of the carriage together. If the light emitted from the opto-electric sensor Beam reflected, missing the skid 30 of this Position and is to be replaced. This is a appropriate control of the sled assembly station 36 further reported. Of course here is also a normal photocell used.

0054Analogously, photocells could to Recognizing the lack of deck boards are used 14th It has in the testing of a prototype but when expedient proved, this mechanical pushbuttons use. These are in the region of the transfer space 35 arranged. These are still present Deck boards 14 is actuated as soon as the pallet 10 by the Carriage of the transfer station 114 in the area of ​​the has been postponed handover place 35th The mechanical probe are then still present Deck boards 14 "pressed". The signal thus obtained is turn to control the board loading station 37 further reported. The pallet 10 is now at the top said chain conveyor lowered.
