Description

[Technical Field]

[0001] The present invention relates to a supply jig used when supplying parts to be used in assembly to an assembly worker. [Background technology]

[0002] Many parts are used in product assembly, and some of these parts have similar shapes and are difficult to distinguish. At production sites, a distribution task is sometimes carried out to supply the necessary parts (specific parts) to assembly workers so that similar-shaped parts are not mixed up during assembly.

[0003] For example, in Patent Document 1, a serving tray (serving jig) is used for serving work, and the serving tray is provided with storage sections shaped to correspond to the type of part. The storage sections are recesses that store the parts, and the serving worker places the parts in the storage sections and supplies them to the assembly worker.

[0004] [Patent Document 1] WO2017 / 149621 publication Summary of the Invention [Problem to be solved by the invention]

[0005] Generally, parts have dimensional tolerances, and even the same part has slightly different shapes. Therefore, parts with multiple bends or irregularities can be difficult to fit entirely into the recess, and even specific parts may not fit. Furthermore, if the recess is made wider to accommodate dimensional tolerances, the wrong part may be placed on the tray. Therefore, there is room for improvement in the structure of the placement jig to ensure that parts with such shapes can be identified reliably.

[0006] The present invention has been made to solve the above-mentioned problems, and aims to provide a serving jig that can reliably identify specific parts even if the parts have shapes with multiple bends or unevenness. [Means for solving the problem]

[0007] The present invention provides an identification unit for identifying a specific part from a plurality of parts having different shapes; A serving jig having a base on which the identification part is provided, the identification portion has a plurality of protrusions provided at positions where they interfere with components other than the specific component, The protrusions are serving jigs that are spaced apart from one another. [Effects of the Invention]

[0008] By configuring as described above, it is possible to reliably identify a specific part even if the part has a shape with multiple bends or irregularities. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] A preferred embodiment of the present invention will be briefly described below, showing the operation of the present invention.

[0011] The present invention provides a feed jig that has an identification unit that identifies a specific part from multiple parts with different shapes, and a base on which the identification unit is mounted. The identification unit has multiple protrusions that are positioned so as to interfere with parts other than the specific part, and the protrusions are spaced apart from one another. This allows the specific part to be attached to the feed jig simply by aligning it with the multiple protrusions, so that even if the specific part has a shape with multiple bends or unevenness, it can be reliably identified regardless of dimensional tolerances.

[0012] In addition, at least one of the protrusions is detachable from the base. This means that the protrusions can be freely rearranged depending on the differences in shape between the specific part and other parts. This allows the number of protrusions to be kept to the minimum necessary to identify the specific part, reducing the number of positions that need to be aligned with the specific part when attaching the specific part to the serving jig, improving the workability of the serving operation.

[0013] The part is a quick fastener for connecting pipes, and has a pair of clamping portions that clamp the outer periphery of the pipes and a connecting portion that connects one end of the clamping portions, and the convex portion includes a first convex portion provided at the connecting portion. The quick fastener has a connecting portion whose shape differs depending on the diameter of the pipes to be connected. By providing the first convex portion at a position where such a difference appears, the specific part can be efficiently identified.

[0014] The part is a quick fastener for connecting pipes, and has a pair of clamping portions that clamp the outer periphery of the pipe and a connecting portion that connects one end of the clamping portions, and the protrusions include a second protrusion provided at the position of the clamping portions. The quick fastener has different shapes of the clamping portions depending on the diameter of the pipe to be connected. By providing the second protrusion at a position where such a difference appears, it is possible to efficiently identify the specific part.

[0015] The part is a quick fastener for connecting pipes, and has a pair of clamping portions that clamp the outer periphery of the pipe, and a connecting portion that connects one end of the clamping portions together, and the protrusions include a first protrusion provided at the position of the connecting portion and a second protrusion provided at the position of the clamping portions. By hooking the connecting portion located at the center of the upper end of the quick fastener onto the first protrusion, the attachment position of the specific part can be determined with respect to the serving jig, and since it is easy to attach the clamping portions to the second protrusion, the workability of the serving work is improved.

[0016] The quick fastener also has a leg extending from the other end of the clamping portion, and the protrusion includes a third protrusion provided at the position of the leg. The quick fastener has different shapes for the connecting portion, clamping portion, and leg depending on the diameter of the pipe to be connected. By always providing a protrusion at the position where the difference in the shape of the quick fastener becomes apparent, specific parts can be reliably identified.

[0017] The identification unit has a first identification part with a first convex portion and a second identification part with a second convex portion, the first identification part and the second identification part have mounting parts of the same shape, the base is square and has a plurality of mounting receiving parts on its periphery to which the mounting parts can be attached, and the mounting receiving parts are provided in the same positions on each side of the base. This allows the identification parts to be attached in the same positions on the serving jig regardless of the orientation of the base, making it easier to assemble the serving jig.

[0018] The serving unit is equipped with multiple serving jigs, which can be connected to each other. This allows the serving jigs to be connected in accordance with the assembly process order, improving the workability of the assembly work. Furthermore, if the assembly process order changes, the order of the serving jigs can be changed to match the changed process order, allowing for flexible response to process changes. [Example]

[0019] An embodiment of the present invention will now be described with reference to the drawings.

[0020] (First embodiment) 1 is a perspective view of a serving jig of the first embodiment. The serving jig 10 is used to identify a specific part 1 from among multiple parts and serve it in an assembly process, and is composed of an identification unit 11 that identifies the specific part 1 from multiple parts with different shapes, and a base 12 on whose upper surface the identification unit 11 is provided. The part referred to here is an object with a shape that has multiple bends and irregularities, and in this embodiment, a quick fastener 2 formed by bending a thin metal plate will be described as an example.

[0021] FIG. 2 is a perspective view of a quick fastener. The quick fastener 2 is a component used to connect pipes, and includes a pair of clamping sections 3 that clamp the outer periphery of the pipe, a roughly U-shaped connecting section 4 that connects one end of each clamping section 3, and legs 5 that extend from the other end of each clamping section 3. The clamping sections 3 are convex outward and have a slit 6 in their center. A flange provided on the end of the pipe is fitted into the slit 6 in an overlapping state, thereby connecting the pipes. Quick fasteners 2 come in various shapes depending on the diameter of the pipes to be connected, and the arrangement jig 10 identifies a quick fastener (specific part 1) of a specific shape from among them.

[0022] FIG. 3 is a perspective view of the first embodiment of the food distribution jig with a specific component attached, and FIG. 4 is a perspective view of a comparative example of the food distribution jig with a specific component attached. In the food distribution jig 10 of this embodiment shown in FIG. 3, the identification portion 11 is composed of multiple protrusions 7 formed by cutting and raising a metal plate. The protrusions 7 are flat and have tapered ends to facilitate attachment of the specific component 1. These protrusions 7 are positioned so that they interfere with components other than the specific component 1, and the protrusions 7 are spaced apart from one another. The shape of the protrusions 7 is not limited to this and may be an L-shaped plate or a cylindrical pin. Meanwhile, the food distribution jig 20 of FIG. 4, shown as a comparative example, has a recess 27 formed by machining the metal plate that serves as the base 22. The recess 27 is shaped like the specific component 1 and serves as an identification portion.

[0023] In the feed distribution jig 20 shown as a comparative example, the specific component 1 can be identified by fitting the entire component 1 into the recess 27. However, components generally have dimensional tolerances, and even specific components 1 vary slightly in shape. Therefore, for components with multiple bends or irregularities, it is difficult to align the specific component 1 with the recess 27 and fit the entire component 1 into the recess 27, and the specific component 1 may not be attached to the feed distribution jig 20. Furthermore, if the recess 27 is made wider in consideration of dimensional tolerances and ease of the feed distribution work, the wrong component may be attached to the feed distribution jig 20. In contrast, in the feed distribution jig 10 of this embodiment, the specific component 1 can be attached to the feed distribution jig 10 simply by aligning the specific component 1 with the multiple protrusions 7, and the specific component 1 can be reliably identified even if the shape of the specific component 1 varies due to dimensional tolerances.

[0024] Furthermore, these protrusions 7 may be formed integrally with the base 12, but it is desirable that at least one of them is detachable from the base 12. This allows the protrusions 7 to be freely rearranged depending on the differences in shape between the specific component 1 and other components, and the number of protrusions 7 can be reduced to the minimum number necessary to identify the specific component 1. As a result, there are fewer locations where the protrusions 7 and the specific component 1 must be aligned when attaching the specific component 1 to the serving jig 10, improving the workability of the serving operation. Note that the protrusions 7 may be detachable individually, or an identification part 8 (see FIG. 6) formed integrally with multiple protrusions 7 may be detachable. Attaching and detaching the identification part 8 will be described later.

[0025] Next, the protrusions 7 will be described in more detail.

[0026] The multiple protrusions 7 are arranged in locations where differences in the shape of the quick fastener 2 appear, and in this embodiment are composed of three first protrusions 71 provided at the position of the connecting portion 4 and two second protrusions 72 provided at the position of the clamping portion 3. One of the first protrusions 71 is arranged inside the connecting portion 4 and the remaining two are arranged outside the connecting portion 4, and these three first protrusions 71 are lined up in a straight line. In addition, the second protrusion 72 is arranged outside the clamping portion 3 and is provided at a position where the clamping portion 3 protrudes outward the most.

[0027] By providing the protrusions 7 at the positions of the clamping portion 3 and the connecting portion 4, quick fasteners 2 whose connecting portion 4 has a different width than the specific part 1 will interfere with the first protrusions 71, and quick fasteners 2 whose clamping portion 3 has a different diameter than the specific part 1 will interfere with the second protrusions 72, making them unable to be attached to the serving jig 10. In this way, by arranging the protrusions 7 in positions where the differences in the shapes of the quick fasteners 2 are apparent, the specific part 1 can be efficiently identified with fewer protrusions 7.

[0028] The worker attaches a specific part 1 from among quick fasteners 2 of various shapes to the above-mentioned serving jig 10. At this time, the worker first hooks the connecting part 4 onto the first convex part 71, and then attaches the clamping part 3 between the second convex parts 72. Because the connecting part 4 is located in the center of the upper end of the quick fastener 2, the attachment position of the specific part 1 to the serving jig 10 can be determined simply by hooking it onto the first convex part 71. This makes it easy to align the clamping part 3 with the second convex part 72, improving the workability of the serving work.

[0029] 4, the height of the specific part 1 protruding from the top surface of the base 22 is reduced by the depth of the recess 27. In contrast, in the serving jig 10 of this embodiment, the specific part 1 is placed on the top surface of the base 12, and the entire specific part 1 protrudes from the top surface of the base 12, making it easier to grasp the specific part 1 than with the serving jig 20 of the comparative example. This improves the workability of attaching and detaching the specific part 1 to and from the serving jig 10.

[0030] Furthermore, quick fasteners of different diameters can be identified by changing the shape of the second protrusion 72. Figure 5 shows a modified example of the distributing jig of the first embodiment, in which the second protrusion 72 is provided with a step portion 72A that is aligned with the small diameter side clamping portion 31 and the large diameter side clamping portion 32. This makes it possible to identify quick fasteners of different diameters.

[0031] It is not necessary to provide both the first convex portion 71 and the second convex portion 72. Either the first convex portion 71 or the second convex portion 72 will suffice as long as it is possible to identify the specific component 1. In this case, making both the first convex portion 71 and the second convex portion 72 detachable from the base 12 makes reassembly easier. The number of first convex portions 71 and second convex portions 72 is not limited to this embodiment, and any number necessary to identify the specific component 1 can be provided as appropriate. Furthermore, convex portions 7 other than the first convex portion 71 and the second convex portion 72 may be provided.

[0032] Next, the attachment and detachment of the protrusion 7 will be described in detail with reference to FIG.

[0033] Figure 6 is an exploded view of the food serving jig of the first embodiment. The food serving jig 10 has an identification part 8 consisting of multiple protrusions 7, and this identification part 8 is configured to be attached and detached to a base 12. The identification part 8 has a first identification part 81 that can attach and detach three first protrusions 71 as a single unit, and a second identification part 82 that can attach and detach two second protrusions 72 as a single unit. In this way, by making it possible to attach and detach protrusions 7 that are provided in the same position on the quick fastener 2 together, the number of steps required to attach and detach the identification part 8 is reduced, and rearrangement of the protrusions 7 can be easily performed.

[0034] The first identification part 81 and the second identification part 82 are provided with mounting portions 91 of the same shape. The base 12 is square, and the periphery of each side is provided with mounting receiving portions 92 to which the mounting portions 91 can be attached. The mounting portions 91 and mounting receiving portions 92 each consist of two screw holes, and in this embodiment, the first identification part 81 is screwed to the upper side of the serving jig, and the second identification part 82 is screwed to the lower side. By providing mounting receiving portions 92 on each side of the base 12 in this way, the identification parts 8 can be attached to the same position on the serving jig regardless of the orientation of the base 12, making it easier to assemble the serving jig 10.

[0035] The serving jigs 10 of this embodiment can be connected to form a serving unit 100.

[0036] 7 is a perspective view of the serving unit of the first embodiment. The serving unit 100 is formed by connecting serving jigs 10, which are prepared for each assembly process, in the order of the processes. The serving jigs 10 can be connected to each other using mounting parts 91 and mounted parts 92. In this embodiment, the serving jigs 10 are connected to each other by screwing connecting plates 93 to the mounted parts 92.

[0037] Product assembly generally consists of multiple processes, with different specific parts 1 used in each process. The figure shows a supplying unit 100 used in assembly that proceeds in the order of process A, process B, and process C, with supplying jigs 10A, 10B, and 10C connected from left to right. The supplying worker installs specific parts 1A, 1B, and 1C, in that order from left to right, and supplies them to the assembly worker. In this way, connecting supplying jigs 10 and arranging specific parts 1 in the order of the processes not only prevents incorrect installation of quick fasteners during assembly, but also makes the assembly work easier.

[0038] Furthermore, the serving unit 100 can change the order by disconnecting the serving jigs 10 from each other. This allows for flexible response to process changes when the assembly process order is changed, as the order of the serving jigs 10 can be changed according to the changed process order. Note that the method for connecting the serving jigs 10 is not limited to this embodiment, and any other method may be used as long as it allows for repeated connection and disconnection.

[0039] (Second embodiment) Next, a second embodiment will be described using Figure 8. Figure 8 is a perspective view of the serving jig of the second embodiment with a specific part attached. The serving jig 30 of the second embodiment is used to identify quick fasteners 2, but unlike the first embodiment, it is provided with a third protrusion 73 located at the position of the leg 5. Below, the serving jig 30 of the second embodiment will be described, focusing on the differences from the serving jig 10 of the first embodiment. Note that the same components as those of the serving jig 10 of the first embodiment will be assigned the same reference numerals and will not be described again.

[0040] The identification portion 11 is made up of a plurality of protrusions 7, including three first protrusions 71, two second protrusions 72, and one third protrusion 73 provided at the position of the leg 5. In this embodiment, the third protrusion 73 is a flat plate located at the tip of the leg 5, but it may also be arranged along the leg 5 and may have any shape. In this way, by always placing a protrusion 7 at a position where the difference in shape of the quick fastener 2 is apparent, it is possible to reliably identify the specific part 1 without providing any more protrusions 7.

[0041] Furthermore, the third convex portion 73 can also be detachably attached to the base 12, similar to the first convex portion 71 and the second convex portion 72. In this embodiment, the third convex portion 73 is part of the second identification part 82, and is detachably attached to the base 12 together with the second convex portion 72. In this way, by combining the convex portions 7 used in one set to identify the specific component 1 into one identification part 8, the number of steps required to attach and detach the identification part 8 is reduced, and the convex portions 7 can be easily rearranged.

[0042] The third protrusion 73 may be detachable separately from the second identification part 82. When a plurality of third protrusions 73 are provided, a third identification part may be provided that allows the plurality of third protrusions 73 to be detachable as a single unit.
