[Technical field to which the invention belongs]

The present invention relates to a power driven conveyor, and more particularly to a conveyor belt having a modular configuration in which a plurality of belt modules are connected in a series.

【0002】

[Conventional technology]

The modular conveyor belt and conveyor chain in the prior art are composed of modular links or belt modules and are connected in the length or width direction. These modules have a predetermined thickness dimension, with the upper surface serving as a transport surface and the lower surface serving as a driven surface. In these modules, a plurality of hinge portions are provided on the side edge portions of each module, and the modules are connected via these hinge portions to form a conveyor belt.

[Problems to be Solved by the Invention]

In the conveyor belt having a modular structure in the conventional technique, each module has a rectangular shape, and each module is arranged so that the horizontal width direction is orthogonal to the transport direction of the conveyor belt. It is configured to be connected side by side, but in order to extend this horizontally long width, a plurality of modules may be butted in the horizontally long width direction. In such a case, the butt joints of the butt modules are not aligned in a row along the length direction of the conveyor belt so that the strength of the conveyor belt itself does not decrease. Conventionally, since the modules are integrated, the butt joints of a plurality of modules, for example, two modules are vertical from the upper surface to the lower surface, and therefore, the portions of the modules butted in the horizontally long direction are simply butt. Therefore, there is a drawback that the load strength is inferior. Further, as the length in the horizontal width direction becomes longer, the hinge pins to be connected also become longer, and the butt module slides in the butt direction to create a gap at the butt, and a part of the object to be transported is caught in such a gap. There are problems such as falling, falling, and pinching of fingers.

【0004】

Further, although the module is molded from plastics or metal, it is integrally molded from the same material, and one surface of the upper surface or the lower surface of the module can be processed so as to be non-slip or easy to slip. However, in order to perform such processing in the molding process, there is a problem that the molding technology becomes complicated only because the module is integrated, and when another member is attached, the work process increases and the cost increases. is there. It is also possible to attach a plurality of rotating parts such as roller structures to the conveyor belt and add new functions such as an increase in the transport speed of the transported object and a handling function to the transport function of the belt. Installation of various rotating parts requires complicated and advanced molding technology, and if the rotating support shaft or roller that supports the rotating parts freely is broken, it is impossible to repair the module equipped with these. Therefore, there is a problem that it has to be replaced with a new one, which makes it extremely uneconomical.

FIG. 9 illustrates an example in which the split modules described above are connected to form a belt conveyor for transport. In the illustrated example, a plurality of modules 320 shown in FIGS. 6A to 6B are connected to form a conveyor. -The belt is 80, and the connected modules are shown as 82 in the figure. As will be apparent from the figure, any number of the modules 320 can be connected in the length or width direction of the conveyor belt to achieve the desired length and / or width dimension of the belt. To connect any number of the modules 320 in the length direction of the conveyor belt, the modules consisting of the combined first member 322 and the second member 323 are connected in the length direction of the belt and are alternately overlapped. The hinge pins 83 may be passed through the holes 26 where the hinge portions 324 and 324 are aligned, and in order to connect the plurality of modules in the width direction of the belt, these modules may be arranged side by side through the seam 86. Good. In FIG. 9, reference numeral 84 constitutes a transport surface of the belt, and the dimension of the belt is such that the transport surface on the upper surface reaches the driven surface on the lower surface (driven by a toothed sprocket or the like (not shown)). Become thick. In this way, in the belt conveyor shown in FIG. 9, the modules 320 are connected, and the arrangement of the second member on the upper surface and the first member on the lower surface is a kind of brickwork or brick butt pattern. Further, the roller structure is supported by the first and second members, and has a reversible structure that can be used even if it is turned upside down. Therefore, the roller structure is configured so that the rotating peripheral side surface of the roller can be seen from both the upper surface and the lower surface.

In the form shown in FIG. 9, the first and second members that are vertically overlapped are overlapped and united and connected without being displaced in the vertical direction, and the seams are vertical in the vertical direction. As shown in Fig. 1, the first members 22A, 22B, and 22C, which are composed of the modules shown in FIGS. 1 and 2, are arranged in the belt width direction via the seam 89, and the second member is placed on the upper side of these members. Members 23A and 23B can be offset and overlapped. With such a configuration, the seam 88 of the upper second members 23A and 23B is located between the first members 22A and 22B.22C, and the seam 88 and the seam 89 are heavy. Instead, the combined modules will have the same seams in the vertical direction, and the beam intensity will increase without bending.

The embodiment shown in FIG. 11 is an example in which the conveyor system 400 uses a conveyor belt composed of belt modules such as the modules with a plurality of rotating balls shown in FIGS. 5A to 5D. In this conveyor system, the conveyor belt 402 with a rotating ball moves upward in the direction of arrow 404. The lower conveyor belt 406 is composed of, for example, a plastic conveyor belt having the high friction surface 408 on the upper surface, and is configured to come into contact with the protruding surface 258 of the rotating ball looking from the lower surface of the belt located on the upper side. There is. (As belts with a high friction surface, for example, there are 900 series flat friction top belts and 1100 series flash grid friction top belts commercially available from Intralocks, Inc. in Harahan, Louisiana, USA). When these two types of belts are crossed at a right angle and the lower belt is moved in the direction of arrow 410, the rotating ball protruding from the lower surface of the upper belt is indicated by contact with the high friction surface of the lower belt. When it rotates in the direction of 412 and conveys an object to be transported such as an envelope with the upper belt, the rotation direction of the rotating ball guides the object to be transported so as to diagonally cross the transport surface of the upper belt. It can be aligned in one direction along the transport direction of the belt to be transported, or can be discharged from the belt to be transported (Note that the figure does not show equipment such as side guards, frame side rails, and discharge plates). ). Similarly, in the conveyor belt composed of the module to which the cylindrical roller of FIG. 9 is attached, a slippery belt or a surface that is not easily worn is arranged on the lower side, and a roller that partially protrudes contacts the lower surface of the module. Thereby, it is possible to align in one direction along the transport direction of the belt that transports the object to be transported. By directing all of the rollers in the same diagonal direction as shown in FIG. 9, all the objects to be transported can be aligned on one side of the conveyor belt, or on either the left or right side of the belt in the transport direction. Diagonal orientation of the rollers in and the other By making the diagonal direction of the rollers on the side to the left and right as in the mirror image, the object to be transported can be divided into left and right sides along the transport direction and aligned, or the center of the conveyor belt in the transport direction. You can also get together at. Further, by making the rotation support shaft of the roller orthogonal to the conveying direction of the conveyor belt and processing the peripheral side surface of the roller into a surface having a high coefficient of friction, the feeding speed of the object to be conveyed on the roller can be increased. it can.

The present invention is not limited. In addition to the above-mentioned preferred embodiments, there are various embodiments of the present invention, for example, a transport surface of a module located on the upper side and constituting a transport surface. It can be made into a staircase (flyts) shape, a bucket shape, a rough surface, a non-smooth surface, and a variety of conveyors by superimposing various lower members and upper members. Belt modules can be configured. Further, the lower member is made of a material suitable for various sprockets and has various strengths and friction characteristics, and is combined with the upper member having various functions to form the module. Another member other than the cylindrical or spherical roller can be held by the first and second coalescing members. Conveyor belt parts such as pop-up shoes, flies, brakes, and levers can be held by the first and second coalescing members. In most of the examples described above, the first and second members are united so that their widthwise end faces are flush with each other in the vertical direction, but one member is displaced in the width direction, for example. The two side-by-side first members may be united so that the abutting ends of the first members are in the middle of the second member in the width direction. Further, the hinge portion provided for coalescence and connection may be provided only on one side of the first and second members, and the other side may be coalesced by a structure such as tabs and studs or a fitting structure. It can also be connected. The through hole of the hinge portion in the above-described embodiment has a structure in which the rotation support pin is surrounded by the peripheral edge of the hole, but even if the through hole is partially missing from the peripheral edge of the hole, the missing hole is formed. It suffices as long as the pin does not come off from a part of the pin.
