Abstract

PROBLEM TO BE SOLVED: To overcome a such problem that automation by mechanical operation or man power of an operator is required for a picking-up operation when performing arrangement movement and a packing work in a process at a factory for an ink jet kit of a plastic model, hard wiring cables which bundle AV/personal computer equipment, porous or net-like shaped general merchandises such as a metal gauze, a sieve and so on, and industrial products such as a key board, a button type electronic calculator and so on which have a shape such as an aggregate in which many small components are arranged.SOLUTION: An automatic catch and release device, which adopts a tentacle made of a semi-hard resin which has an alphabetical "J" shape as a basic shape, is fitted to an arm tip of a robot arm located at a work station on a line at which it is necessary to pick up an object, and thereby achieving automation. A core of this device exists in a system itself which daringly avoids a mechanical operation which is likely to increase in cost, and catches an object by hitching a tentacle to the object.SELECTED DRAWING: Figure 4

Description

  The present invention is a product catch-and-release device in the process of manufacturing and packing various industrial products and parts.

  Plastic model parts by injection molding are handled as a single molded product without separating the runner in the factory line. In this injection kit manufacturing factory, operations such as placement movement and packaging after molding are performed by the hands of workers.

  In addition, bundled connection cables for AV equipment and personal computer related equipment, miscellaneous goods such as wire nets and bags, wire parts such as various springs and telephone cords, PC keyboards and push button calculators, etc. In the manufacturing assembly / packaging process of industrial products such as assemblies in which many small parts are arranged, the basics of catch and release of these products are mainly based on mechanical operation and vacuum. I am not aware of patent documents and non-patent documents related to other than these methods.

  Each part of the plastic model by injection molding does not need to be separated from the runner after molding, unlike parts of general industrial products. Each part is handled as a single molded product, with many and many kinds of small parts arranged on a square plane connected together by a runner and gate. There are a wide variety of shapes, including the arrangement of runners and gates, and the number of types is inevitably increased. The injection kit required to complete one plastic model has different molding colors, and even a simple plastic model may require several sets. Therefore, if you handle dozens of types of plastic models in one factory, you need to handle several times as many injection kits as the number of models. Automation is indispensable for handling on these production lines, but in the case of arrangement movement and packing work that must be done by picking up these, it is necessary to automate catch and release at low cost corresponding to this. There are too many types and it is difficult to generalize, and it is necessary to rely on manual work by workers.

  Also, in the handling of industrial products such as PC keyboards and push button calculators in the manufacturing and packaging process, when these products are caught and released, including the various attachments included, High-cost mechanical operation or vacuum is the mainstream.

  On the production line that handles the injection kit, the automatic catch and release device of the present application is attached to the arm tip of the robot arm installed at the work position where it is necessary to pick up the kit. The catch method itself of the injection kit, which is the core of the device, does not employ mechanical operation that tends to be costly, and it is basically a device that can be used for general catch and release regardless of the type of injection kit.

  To catch the injection kit at the core of the device, use semi-rigid resin tentacles based on the letter “J”, and hook this tip onto each part of the injection kit, runner or gate. And catch. The tentacles are passed through a large number of holes opened in the shape of a plane base, but these tentacles only prevent falling off, and the tentacles are not synchronized, rotate 360 degrees based on the shaft, and also in the vertical direction Move freely. This makes it possible to put the tentacles in contact with each other and hook the tip of the tentacles so that they are entangled with the shape of each part, runner, and gate part in an image that covers a complex uneven injection kit. to catch. This method can be applied to semi-finished products and finished products as long as it is a shape that does not stop at only the parts but catches tentacles.

  The introduction of an automatic device that features easy-to-catch and release tentacles makes it possible to automate processes that previously had to rely on human hands. In addition, since it is a general-purpose automatic device that does not require the preparation of a catch attachment dedicated to each injection kit, there is no need to make a large capital investment.

  In addition to handling injection kits and various wire parts, industrial products such as aggregates with many small parts arranged, such as PC keyboards and push button calculators, are completed. Can also be used to handle goods. This is because these products have attachment gaps between the key buttons, so that the tentacles of the present device can easily enter the gaps. In addition to bundled connection cables for AV equipment and PC related equipment, miscellaneous goods such as wire nets and bags, various springs and telephone cords, etc. On the other hand, the catch method using the tentacles of the present application is extremely effective.

An embodiment of claim 1 is first described. A number of tentacles whose basic shape is the letter “J” made of a semi-rigid resin material with a round cross-section is prepared. The tentacle includes a tentacle hook portion 2, a tentacle arm portion 3, and a tentacle stopper portion 4. The tentacle stopper portion is formed by heat melting, or is formed by heat welding another piece. The cross-sectional diameter of the tentacle is desirably about 0.5 mm. If it is too thin, the hook strength of the tentacle hook will be insufficient, and the waist of the tentacle arm will be too soft. On the other hand, if it is too thick, the tentacle hook part will damage the opponent or the tentacle arm part will lack flexibility. There are tentacles A 1 and tentacle B 10 and tentacles C 11 as an example of a tentacle. (See Figures 1, 2, and 3)

  A tentacle base 5 made of Duracon resin is attached to the frame 7. Next, the elevator board 9 is attached to the elevator 8, and the tentacle upper base 6 is fixed under the elevator board. Then, this lifting device is attached to the frame. This is a method for moving up and down the tentacle base that moves integrally with the elevator by injecting compressed air from the air inlet 12 of the elevator or releasing it from the elevator. (See FIGS. 4, 6, and 8)

  The tentacle arm portion 3 in which the tentacle hook portion 2 has been formed in advance is passed through all the small holes of the tentacle lower base 5 and the tentacle upper base 6, and the tentacle stopper portion 4 is formed by melting or welding to finish the attachment of the tentacle. . At this time, the tentacles are not synchronized with each other, and are merely prevented from falling off by the tentacle stopper portion, and are rotated 360 degrees based on the tentacle arm portion to freely move in the vertical direction. The diameter of the small holes of the tentacle lower base and the tentacle upper base through which the tentacle arm section passes is desirably about five times the diameter of the tentacle arm section by providing play. (See FIGS. 5, 7, and 9)

  When compressed air is injected into the elevator 8, the tentacle upper base 6 is pushed down together with the elevator board 9, and the tentacle hangs down from the bottom surface of the tentacle lower base 5. While maintaining this state, the apparatus is brought as close as possible until immediately before the bottom surface of the tentacle base touches the injection kit 13. Then, each tentacle moves up and down, rotates, and bends so that it is entangled with the shape of the opponent's injection kit, while the tentacle hook part 2 at the tip is caught on the parts of the injection kit, the runner and the gate part, and the injection kit To catch. At this time, it is not necessary that the tentacle hook portions of all tentacles are caught by the opponent. (See Figure 10)

  When releasing the caught injection kit 13, the tentacle upper base 6 is pulled up together with the elevator 9 by the force of the internal spring by releasing compressed air from the elevator 8. Then, each tentacle is also pulled up at the same time, and the tentacle hook portion 2 is also drawn into the hole of the lower tentacle base 5. Then, since the tentacle hook part hooked on the injection kit is made of resin, the tentacle hook part extends without being able to withstand it, and releases the injection kit. (See FIGS. 11 and 13)

Next, an embodiment of claim 2 will be described. Here is an embodiment of the present apparatus that handles a keyboard of a personal computer. The tentacles whose basic shape is the letter “J” of the alphabet is basically the same system as the tentacles of claim 1 in that the tentacle hook portion 2, the tentacle arm portion 3, and the tentacle stopper portion 4. However, large and small tentacle hooks are attached in two directions facing each other from the tip of the arm. Further, since the weight of the object is relatively heavy, the cross-sectional diameter of the tentacle is desirably around 0.7 mm. While embodiments of the tentacles are tentacles D 14, while this same shape, prepared in conjunction with the tentacles D1 15 what the length of the feeler arm portion is slightly longer. (See FIGS. 14 and 15)

The method for attaching the base plate 6 on the tentacle lower base 5 to the elevator base 8 on the frame 7 is the same as that of the first aspect. There is no change in the method of raising and lowering the tentacle base that moves integrally with the elevator by injecting compressed air from the air inlet 12 of the elevator or releasing it from the elevator. Next, the tentacle arm portion 3 is passed through all the small holes of the tentacle lower base 5 and the tentacle upper base 6, and the tentacle stopper portion 4 is formed by melting or welding to attach the tentacle. To the small holes of the tentacles base open at this time checkerboard pattern, alternately arranging the tentacles D 14 and tentacles D1 15 both vertically and horizontally. In addition, the tentacles are not synchronized with each other, and by simply preventing the tentacles from falling off, the tentacles are rotated 360 degrees based on the tentacle arm portion, and are freely moved in the vertical direction. The diameter of the small holes of the tentacle lower base and the tentacle upper base through which the tentacle arm section passes is desirably about five times the diameter of the tentacle arm section by providing play. (See FIGS. 16, 17, and 18)

  When compressed air is injected into the elevator 8, the tentacle upper base 6 is pushed down together with the elevator board 9, and the tentacle hangs down from the bottom surface of the tentacle lower base 5. While maintaining this state, the apparatus is brought as close as possible until just before the bottom surface of the tentacle base touches the keyboard 16. Then, each tentacle enters the gap between the key buttons of the keyboard, and the tentacle hook portion 2 at the tip is caught to catch the keyboard. At this time, it is not necessary that the tentacle hook portions of all tentacles are caught by the opponent. (See Figure 20)

  When releasing the caught keyboard 16, compressed air is released from the inside of the elevator 8, whereby the tentacle upper base 6 is pulled up together with the elevator 9 by the force of the internal spring. Then, each tentacle is also pulled up at the same time, and the tentacle hook portion 2 is also drawn into the hole of the lower tentacle base 5. Then, the hooked tentacle hook part extends and comes off, and the keyboard is released. (See Figure 21)

  The greatest feature of the apparatus is the catch and release method itself of an object such as the injection kit 13 or the keyboard 16. Among them, semi-rigid resin tentacles were adopted, but in addition to the above embodiment, a method of attaching a plurality of tentacles to each hole of the tentacle base or different hook parts on one tentacle base There is also a way to attach a tentacle of shape. On the other hand, depending on the overall shape of the object to be handled, the shape of the upper and lower tentacle bases to which the tentacles are attached is changed according to the shape. For example, objects such as plastic or wire mesh cages and balls can be dealt with by making them arc-shaped or dome-shaped.
