Machine blowing and molding thermoplastic polymer vessel

[Detailed Description of the Invention]

Since the present invention blows the workpiece of thermoplastic polymer in order to produce the thermoplastic polymer container blown and fabricated, it stores it in a making machine and holds so that release is possible, it relates to the device which operates a zipper. the shape of a fork which carries out sliding engagement of the chunk which stores the workpiece of thermoplastic polymer and it holds so that release is possible in order to produce the container of thermoplastic Borimer which blew the present invention in one field and was fabricated at an operation To eat mechanism -- the end slide which it has is started. The present invention relates to the device which has the slide which has a fork-like end which engages with the ring of a collet t What is zipper so that it may operate, the collet, i.e., the zipper, which receive thermoplastic child * Limmer's reserve molded product in another Therefore, and it holds so that release is possible. A blowing-in forming process is an important method commercially, in order that a metaphor may produce the container of thermoplastic polymer like the bottle which carried out for biaxial Arrangement. In order to produce the container (for example, bottle) which carried out for biaxial Arrangement, there are two important methods used commercially now substantially. The 1st method makes a hot reserve molded product (generally ejection or the method of pushing out), Carry out A jet ON of the pressurization air to blowing a hot reserve molded product with an axis generally, and moving it to a form block into a hot reserve molded product, a reserve molded product is made to weld by pressure to the blank of a model, and it lengthens in the direction of an axis, and the direction of the circumference, and ranks next with blowing and fabricating a container within a model, It comprises taking out from the model open [ the container which carried out for biaxial Arrangement ]. In the 2nd method, the normal temperature or the cooled reserve molded product made previously is blown, and it heats again even to a molding temperature profile, The container which carried out for biaxial Arrangement is picked out from the model open [ developed the reserve molded product in the direction of an axis, blew the heated reserve molded product and closed person [7 and a model around the reserve molded product so in the blank of the form block, was simultaneous with it, or opened in the direction of 1g of circles so that it might be adapted to the blank of a model after that, next ]. In the 2nd method, the device which it was separately [ from blowing-in molding equipment ] frequent, and a certain distance opened performs production of a reserve molded product. This 2nd method is learned and is often called a re-heating blowing-in forming process. the workpiece by which blew the container of thermoplastic polymer and injection molding was carried out in forming-1 * How to do and which carried out preliminary fabrication -- or the workpiece which is the pushed-out pipe which was made into the neck which closed one end and the other end opened wide, and the shape where the screw thread was generally provided and which carried out preliminary fabrication can be used. These injection molding and the reserve molded product of the pipe which whether it was carried out pushed out and was fabricated are test tubes which are the neck which the end in which the often closed end carried out bowl music, and it provided the screw thread opened wide. Such a reserve molded product grasps the neck opened wide, and releases the container which was carried through each stage of a re-heating blowing-in forming process with the carrier device, and it ranked next, and was blown and fabricated from a carrier device. When it is used in order to carry a reserve molded product covering other various stages of this method in relation to the present invention in the blowing-in forming process which produces the container of thermoplastic polymer, there is a stage of heating the reserve molded product which is conveyed by the River carrier through a heating stage and which was fabricated previously. In order to produce the container of thermoplastic polymer economically, for using a high production rate with blowing-in molding equipment, it is necessary to load a reserve molded product in a carrier (for example, 1000 to 2000 containers per hour) certainly very quickly. It is quantity (in order to receive a reserve molded product to use - production rate, it is necessary to operate a reserve molded product carrier quickly and certainly to use) such. In order to operate reserve molded product Gearier such, it is Nara, if the device which operates a carrier can be trusted, it acts certainly quickly and durability is not high (-.). Till the former, in order to hold the reserve molded product conveyed covering the stage of a blowing-in forming process so that grasping L~release is possible, the mechanical contrivance which operates a reserve molded product does not operate a carrier suitably, and carries out l~Loudspeaker breakage so that it cannot be said as satisfaction at all but a reserve molded product may be received, It does not function suitably and a reserve molded product carrier may not operate a reserve molded product suitably again. Do not function suitably such, or will blow in not operating a carrier suitably, and Pleasure will be produced in a making machine, or a reserve molded product and a container will be lost. One object of the present invention is to make it operate so that a reserve molded product can be trusted certainly quickly, in order to blow a reserve molded product in order to produce the container of thermoplastic polymer, to accommodate in molding equipment and to hold so that release is possible. One purpose of everything but the present invention is to provide a device with the durability which operates the reserve molded product carrier who blows the reserve molded product of thermoplastic polymer, accommodates in a making machine, and holds so that release is possible and which operates so that it can be trusted [ whether it is also t~ or ] certainly quickly. The reserve molded product carrier who one object of further others of the present invention receives the reserve molded product of thermoplastic polymer, and holds so that release is possible, It is providing the blowing-in making machine which has a device with the durability operated so that a reserve molded product's may be received, release is possible and reserve molded product Gearier's can be trusted certain moreover quickly for a maintenance 1 * To reason. The other objects and advantages of the present invention think that they become whether to be Ming by the following Straight and above-mentioned claims. the present invention -- getting twisted -- the zipper starting device which changes from the slide which has the fork-like end with which the frame was equipped movable so that it might engage with the (a) frame and (/l) a zipper to the blowing-in making machine which has a zipper which receives the article of Hot plasticity polymer and it holds so that release is possible is provided. the shape of a fork -- the end slide which it has is made to exercise the inside of a frame from a non-engaging-of-clutch position by even the zipper interruption-of-machine-operation position, is returned to a non-Engagement position, operates a zipper by the same zipper interruption-of-machine-operation movement or the independence movement of a slide, and receives the article of thermoplastic polymer, and it makes it hold it so that release is possible Drawings 2, 6, and 4 are explained for the present invention about the desirable example of one reference I2 The. It is an example with the part or perspective view of carrier Senori used together with the zipper starting device of the present invention in Drawing 1. Roller 218 which carrier assembly 22 which blows reserve molded product 202 of thermoplastic polymer, is put in and blown into a making machine, and is conveyed covering the stage of the gods of a forming process attached to gear rear main part 200 You are made to exercise by chain 62 connected to the driving means which is supported on rail 42 and is not illustrated. Gurinoand' provided in the zipper in order to prolong zipper 206 which holds reserve molded product 202 so that release is possible and to hold reserve molded product 202 by this zipper from carrier main part 200 so that release is possible! It is slidably equipped with release ring 220 which operates ' (not shown). In zipper 206 of carrier main part 200, the shaft in the air has projected to the side opposite to, this shaft is connected to zipper 206, and it is equipped with Sprockets l-210. Sprocket 210 is made to rotate by the chain which rotates a shaft, therefore zipper 206. When carrier assembly 22 of Drawing 1 is positioned near the zipper starting device of the present invention without having received reserve molded product 202, the zipper starting device of the present invention engages with zipper 206, release ring 220 is operated, and zipper 206 is made to receive a reserve molded product. If reserve molded product 202 is inserted in zipper 206, separate the starting device of the present invention from zipper 206, and reserve molded product 202 is made to hold by zipper 206, so that release is possible, then carrier Senori 22 will move and blow in into the next position in a blowing-in making machine, and will perform the next stage of a forming process. Zipper starting device 600 or the upper surface figure concerning the present invention has shown to Drawing 2, and sliding member 602 is in the zipper interruption-of-machine-operation advance position on release ring 220 in this figure. It shows and comes out to Drawing 2, and zipper starting device 300 has a certain frame 601 which provided two Sideways material 317 like. Frame 301 is equipped with slide Filtration 02 movable, piece 304 of Also a finger provides and comes out with arm 616 and accommodation slot 307, and this Schley l- *302 has a certain fork-like Endless 03. Arm 616 is equipped with fork-like end 303 by bolt Filtration 1 Filtration. roller 305 included in level slot Filtration 07 provided in each flank 617 should take to A = Muro 16, and be effective against it -- it comes out. Slide 302 prevents it from moving to the side during movement using guidance roller 606 which went into slot 607 of the arm and was attached to the bottom of frame Filtration 01. Flank 617 of frame 301 is equipped with liquid pressure cylinder 308 which gives movement to slide 302 by Trunnion Filtration 09, it takes to U-link 610 of slide"302 by connector Filtration 11 Someone 12, and has I got it. piston rod 407. Proximity switch 614 and Filtration 15 detect advance and the retreat position of slide 302, respectively, and display them. These switches are safeguards and do not constitute a part of present invention. If Drawing 6 is referred to, it will set to the device of the present invention, It is shown in the state where it is in the zipper actuated position where Schley 202 moved forward, release ring 220 is depressed, and this ring depresses tab 405 of zipper 206, operate zipper 206 by that cause, receive reserve molded product 401, and it is making it hold so that release is possible, and is To go. Slide Filtration 02 of release ring 220 is an example in a shadow figure again about zipper 206 or the position which it Coalescence to tab 405 if detached, but does not depress it. In the position shown in Drawing 6, Bi * Stone stick 407 of liquid pressure cylinder 308 retreats in a cylinder, It is welded by pressure and positioned on the hollow 4040 surface established in the upper surface of slot 406, front roller 305 is welded by pressure to a fork-like end by inner side 317 of frame 601 again, and back roller 605 is it. Downward movement which depresses release ring 220 is made to perform to fork [ of slide * Filtration 02 ]-like end 60 Filtration. Roller 305 has two incomes with slot 406, and determines advance and the retreat quantity of motion of slide 302. Schley'302 is made into the retreat position away from the zipper in Drawing 4, and the zipper starting device of the present invention is an example. It holds by zipper 206 by movable Gurino and xi501 which pushed for the device of the present invention in Drawing 4, and equipped pin 502 with - The and reserve molded product 401 again and by which spring load was carried out, and zipper 206 and reserve molded product 401 are examples with a fragmentary sectional view. If Schley 1- *302 is in the retreat position which separates from a zipper, a slide is level, and it will move forward, and back roller Filtration 05 will escape from hollow 404, and will weld by pressure piston rod 407 of liquid pressure cylinder 608 to the back end of slot 403. With reference to Drawing 6 and Drawing 4, an operation of the zipper starting device of the desirable example of the present invention is explained below. Schley 302 is made into the retreat position shown in Drawing 4, and is started, and piston rod 407 of liquid pressure cylinder 608 is advanced, Back roller 605 is extricated from Notch 404 provided in slot 40 Filtration of Sideways 17 of frame 601, and is welded by pressure to the rear of slot 403, Release ring 220 of zipper 206 sits down to tab 405 of movable gripper 501 by which spring load is carried out with which pin 502 was equipped, and gripper 501 has it in the reserve molding position which moved forward again. Piston rod 407 which led liquid pressure fluid to liquid pressure cylinder 308, and was attached to arm Filtration 16 of slide Filtration 02 by connector Filtration 11 is retreated. front roller Filtration 05 welding slide 602 by pressure to the front part of slot 406 by that cause, and coming to suspend the forward motion of slide 602, if piston rod 405 retreats, and coming under back roller Filtration 05 -- again -- again -- or it is made to move forward until piece 304 of a finger comes on release ring 220 If piston rod 407 retreats slightly further again, apply upward power to the back end of arm 616 of slide 602, and center slide Filtration 02 on front roller Filtration 05. Release ring 220 is made to contact and this ring is made to be depressed, as carry out pivot movement, make back roller 305 go into Notch 404, slide 302 is kept from carrying out pivot movement more by that cause and piece 304 of a finger of fork-like end 606 was shown in Drawing 6. When release Ring 2 Filtration 0 is depressed, a ring is welded by pressure to gripper 502 and makes a retreat position rotate it centering on pin 502. If it does in this way, zipper 206 will operate and will receive reserve molded product 401. If it inserts in zipper 206 which made slide 602 the advance position, retreated piston rod 407, and operated reserve molded product 401 as shown in Drawing 6, The direction of a flow of the liquid pressure fluid to liquid pressure cylinder 608 is made reverse, piston rod 407 is advanced, at first, downward power is applied to the back end of arm 616, and To 0 bot movement of the slide 602 is carried out a center [ front roller Filtration 05 ], Back roller 305 is displaced from Notch 404, piece 604 of a finger is pulled up from release ring 220, and the reserve molded product grasping position of front is made to carry out pivot movement of a release ring or the gripper 501 by which enabled it to go up and spring load was carried out by that cause a center [ pin 502 ]. Continuing makes back roller Filtration 05 weld advance by pressure to the back end of slot 406, and piston rod 407 stops retreat movement of slide 602 by that cause, and separates fork-like Endless O Filtration from zipper 206. At the present invention, it is a container (for example) of thermoplastic polymer. in order to receive the reserve molded product of thermoplastic polymer in the machinery which blows and fabricates a bottle and to hold so that release is possible, the zipper which has Gurino and xi assembly, and the release ring with which the external surface of the zipper was slidably equipped in order to engage with it is operated -- act quickly and certain It is unexpectedly advantageous if the device which can trust it and has durability is formed. - [ 1st-figure/ the /-less ] About the present invention, although it carried out and being explained with reference to Drawing 4, this explanation is not the intention which limits the present invention. Therefore, it has a zipper which receives the reserve molded product of thermoplastic polymer and it holds so that 2 release is possible, and a zipper is a housing, To the machinery which blows and fabricates the container of the thermoplastic polymer which comprises the release ring with which the exterior of the gripper assembly which takes in a housing and grasps a Inquired and preparatory molded product so that release is possible, and a housing is equipped slidably, and which engages with gripper Sensiri, In order to make a zipper receive a reserve molded product and to make it hold so that release is possible, the device which operates a zipper is formed, and it is this starting device. a) The frame supported movable, b) The slide which has a fork-like end which engages with the release ring of a zipper, a means to make C slide exercise irreversibly, and the limit means which controls that d slide * exercises the inside of a frame horizontally, e) Comprise a pivot means to carry out pivot movement of the Schley [The to the limit of the forward motion, and a means which is fork-like ends in order to operate f release ring to make it exercise almost perpendicularly. In one specific example of the present invention, the fork-like end of slide * has a plurality of openings which engage with a plurality of zippers, operate it, engage with the reserve molded product of thermoplastic polymer, and it makes hold so that release is possible. In another specific example of the present invention, the fork-like end of slide ゝ can have a single opening which engages with one zipper and operates it. In one example of further others of the present invention, it is considered as a means to make Schley l-' exercise irreversibly, and a liquid pressure cylinder can be used. Or an air cylinder can be used for making slide ゝ exercise. One means to give almost perpendicular movement to the fork-like end of a slide, or means another although it is an example in Drawing 6 and Drawing 4, and such movement is given to a fork shaped part can also be used. Therefore, for example, a Facing tapered shape side can also be used for the almost same part as Notch 404 behind the bottom of Drawing 3 and Drawing 4 along with the length of slot 403 instead of Notch 404 of the upper surface of slot 40 Filtration. Such, when Schley ·ゝ602 carries out forward motion of the Argument-] 2-figure surface, it is made raised in the part of the surface from which back roller Filtration o5 was pulled up, rotates front low 265 for Schley l- *302 as a center by that cause, and gives almost perpendicular movement to fork-like end 606. A person skilled in the art will be permitted other means for which the fork-like end of a slide is made to exercise almost perpendicularly. Any one of some structures other than a flat piece structure of two copy of slide Filtration 02 shown in Drawings 2, 6, and 4 may be sufficient as the slide of the device of the present invention. for example, slide * -- a flat part -- carrying out right also with the structure of a piece -- \. It is an understanding to change and change into others variously, without deviating from the principle of the present invention and the above-mentioned claim to the device of the present invention at a person skilled in the art, and it is today.
