Such "folding work of folding the flat product mount 100", "work of passing the hook piece 102 through a specified number of annular hair elastics", "work of inserting the tip 102a of the hook piece 102 into the slit 103", and Conventionally, the series of operations of "packing the completed hair elastic assembly into a bag or box" has been performed manually. was difficult to insert into the slit 103 . That is, in order to prevent the hanging and displayed hair rubber assembly from falling due to the hook piece 102 slipping out of the slit 103 over time, the width of the slit 103 is made wider than the width of the tip 102a of the hook piece 102. Although it is necessary to narrow it, this makes it difficult to insert the hook piece 102 into the slit 103 . In addition, due to the nature of the product that the main sales channel of the hair rubber assembly is a 100 yen uniform shop, etc., it is required to manufacture the product mount 100 as inexpensively as possible. The existence of a considerable number of product mounts 100 with almost no slits 103 due to the ease of slipping has also been a factor in making it difficult to insert the hook pieces 102 . Further, if force is applied when inserting the slit 103, the hook piece 102 or the slit 103 may be damaged, or the mount body 101 may be scratched to impair its commercial value. It took a lot of time and effort to do it. As described above, conventionally, it takes a lot of time and effort to insert the hook piece 102 into the slit 103 while executing a plurality of processing steps, and furthermore, the trend of decreasing the number of side workers is accelerating in recent years. There was also a demand for automation of the work.

As a device for handling ring-shaped products, for example, as disclosed in Patent Document 1, a configuration is known in which an O-ring to be conveyed is held by a hand portion and mounted on the outer peripheral surface of a paper feed roller or the like. there is However, even if such a device is used for manufacturing the above-described hair elastic assembly, it is limited to automating the insertion of the hook pieces 102 into the hair elastics, and the insertion of the hook pieces 102 into the slits 103, which is a particularly complicated operation, can be omitted. Cannot be automated.

As shown in FIGS. 1 to 4, when the product mount 100 is conveyed from the upright position P1 to the supply position P2, the supply device 20 directs the tip portion 102a toward the upright hook piece 102 to form a plurality of ring-shaped products. By supplying 110 , the hook pieces 102 are inserted through the plurality of ring-shaped products 110 . In order to facilitate understanding of the overall configuration of the manufacturing apparatus 1, the schematic configuration of the supply device 20 is indicated by dashed lines in FIGS. 1 and 4, and the illustration of the supply device 20 is omitted in other figures. The structure of the supply device 20 is not particularly limited. For example, a plurality of ring-shaped products 110 are superimposed and conveyed directly above the hook piece 102 by a belt conveyor or the like, and directed toward the hook piece 102 in an upright state. A configuration for dropping the ring-shaped products 110 or a configuration for grasping a plurality of ring-shaped products 110 using a hand unit or an articulated robot disclosed in Patent Document 1 and conveying them toward the hook pieces 102 can be mentioned. The manufacturing apparatus 1 of the present embodiment is configured to bundle six ring-shaped products 110 each, but the number is not necessarily limited to six as long as the number can be bundled by the product mount 100 .

When the product mount 100 is conveyed from the supply position P2 to the push-in position P3, the pushing-in device 60 includes a pair of holding members 61, 61 for holding both sides of the other end side 101b of the mount main body 101, and a slit at the other end side 101b. The other end side 101b of the mount main body 101 is sandwiched between a pair of clamping members 61, 61, and the pressing member 62 is operated while maintaining the upright state. The gap of the slit 103 can be widened.

When the product mount 100 is transported from the push-in position P3 to the folding position P4, the folding device 30 includes a holding member 31 for holding one end side 101a of the mount main body 101 in a horizontal state, and A pressing member 32 is provided to bring the slit 103 closer to the tip 102a of the hook piece 102 by pressing and bending the 101b.

The insertion device 40 includes an articulated robot 41 having a multi-axis (for example, 4 to 7 axes) structure in which a plurality of arms are rotatably connected via joints, and a rotation mechanism at the tip of the arm of the articulated robot 41. and a gripper 42 attached to the . At the folding position P4, the insertion device 40 holds the hook piece 102 with the holding portion 42 while maintaining the folded state of the other end side 101b of the mount main body 101 by the pressing member 32, and the tip portion of the hook piece 102 is held. By inserting 102a into the slit 103, the ring-shaped product assembly 120 is manufactured.

Next, a method for manufacturing the ring-shaped product assembly 120 using the manufacturing apparatus 1 having the above configuration will be described. First, the product mount 100 is conveyed from the container 11 to the standing position P1 in a horizontal state, and is temporarily stopped at the standing position P1. I do. By this erecting step, the other end 101b of the mount body 101 and the tip 102a of the hook piece 102 are erected substantially perpendicularly to the one end 101a of the mount body 101. As shown in FIG. When using the product mount 100 in which the other end 101b and the hook piece 102 are erected in advance with respect to the one end 101a of the mount main body 101, the configuration without the erecting device 50 and the erecting process may be employed. In this case, it is necessary to raise the other end 101b and the hook piece 102 with respect to the one end 101a of the mount body 101 manually or by another device in advance, and supply it to the supply position P2, which will be described later, while maintaining that state. Therefore, in order to automate a plurality of processes as much as possible, it is desirable to have the erecting device 50 and the erecting process as in the present embodiment.

Next, after the product mount 100 is conveyed from the standing position P1 to the supply position P2 and temporarily stopped at the supply position P2, the supply device 20 is operated to supply a plurality of ring-shaped products 110, which is a supply step. Through this supply process, the hook pieces 102 are inserted through the plurality of ring-shaped products 110 .

Next, after the product mount 100 is transported from the supply position P2 to the pushing position P3 and temporarily stopped at the pushing position P3, the pushing device 60 is actuated to widen the gap of the slit 103, thereby performing a pushing process. This pushing process will be described with reference to the process perspective view shown in FIG.

First, as shown in FIG. 5(a), after the product mount 100 is conveyed to the pushing position P3, the pair of holding members 61, 61 of the pushing device 60 are rotated along the vertical plane as indicated by arrows. Thereby, as shown in FIG. 5(b), the upper part of the other end side 101b of the mount body is clamped by the pair of clamping members 61, 61. As shown in FIG. Next, by advancing the pushing member 62 in the direction indicated by the arrow in FIG. As shown in FIG. 5(c), the upper portion of the slit 103 is pressed by the front end surface of the pressing member 62 formed in a strip shape. Thereby, a step is generated between the upper portion and the lower portion of the slit 103, and the gap of the slit 103 can be widened. In this structure, the width of the slit 103 is always narrower than the width of the hook piece 102 in order to prevent the hanging and displayed hair rubber assembly from falling due to the hook piece 102 slipping out of the slit 103 over time. Since the main sales channel for the body is 100 uniform, the mount is manufactured at the lowest possible cost and does not meet the quality of slit holes suitable for automation, so if the mount with almost no slit holes is excluded, it will be delivered There are not a few mounts that have almost no slit holes to the extent that the yield of the finished product is considerably reduced for the number of mounts that are used. It removes the wall that has hindered the automation of this process, such as the fact that even if it is done manually, it needs to be done with great care and time, as the backing itself may be scratched to detract from the product value. This is a big point.

After the pressing step, the product mount 100 is conveyed from the push-in position P3 to the folding position P4, temporarily stopped at the folding position P4, and then the folding device 30 is operated to move the other end 101b of the mount body 101. to the one end side 101a. Then, while maintaining the bent state of the other end side 101b in the bending step, the insertion device 40 is operated to perform the insertion step of inserting the tip portion 102a of the hook piece 102 into the slit 103. FIG. The bending process and the inserting process will be described with reference to the process perspective view shown in FIG.

First, as shown in FIG. 6A, after the product mount 100 is conveyed to the folding position P4, the holding members 31 of the folding device 30 are rotated along the horizontal plane from both sides of the product mount 100, The one end side 101 a is held by the holding member 31 by advancing the leading end portion 31 a above the one end side 101 a of the mount main body 101 . The holding member 31 may be configured to rotate up and down along a vertical plane. Next, by advancing the pressing member 32 of the folding device 30 in the direction indicated by the arrow in FIG. By pressing, the other end side 101b is bent so that the slit 103 is positioned below the tip portion 102a of the hook piece 102. As shown in FIG.

Then, while maintaining the folded state of the other end side 101b of the mount main body 101 by the operation of the folding device 30, the insertion device 40 is operated, and the cylindrical rod 42a and the band plate 42b provided in the grip portion 42 are hooked. By gripping the piece 102 and moving the tip 102a of the hook piece 102 toward the slit 103, the tip 102a can be inserted into the slit 103 as shown in FIG. 6(c). In this way, the ring-shaped product assembly 120 in which the plurality of ring-shaped products 110 are bundled by the product mount 100 can be continuously manufactured. A plurality of manufactured ring-shaped product aggregates 120 can be, for example, housed in a vinyl bag or the like, and after the opening is folded and sealed, it can be transported to the next step.

According to the manufacturing apparatus 1 of the present embodiment and the manufacturing method of the ring-shaped product assembly using the same, in the folding process, the folding device 30 folds the other end of the mount main body 101 so that the slit 103 becomes the hook piece. By approaching the tip 102a and inserting the tip 102a of the hook piece into the slit 103 by the insertion device 40 in the insertion step, the hook piece 102 can be easily and reliably inserted into the slit 103. Therefore, the ring-shaped product assembly 120 can be manufactured efficiently.

As shown in FIG. 7A, the tip portion 102a of the hook piece 102 of this embodiment is widened so that the width W is wider than the widthwise length L of the slit 103, and when it is inserted into the slit 103, 7(a), a portion of the tip 102a of the hook piece 102 is inserted in the direction inclined with respect to the slit 103 (the direction indicated by the arrow in FIG. 7(a)), and then, as shown in FIG. 7(b), the slit 103 By further inserting while changing the orientation in the direction perpendicular to the hook piece 102, the entire tip 102a of the hook piece 102 can be inserted into the slit 103 as shown in FIG. 7(c). In the insertion step, by operating the gripping portion 42 of the insertion device 40 in this manner, the tip portion 102a of the hook piece 102 can be easily inserted into the slit 103 while preventing the tip portion 102a of the hook piece 102 from being damaged, and , the inserted distal end portion 102a can be reliably prevented from coming out of the slit 103 unexpectedly.
