With the drive, the collection device 21 is moved in the front-rear direction, that is, between the standby position and the collection position.
[0017]
The main body case 39 of the collection device 21 is supported so that four collection boxes 41 as collection containers can be pulled out when four molds are mounted on a resin molding machine, for example. Is provided with a loading portion 43a whose upper portion slightly protrudes from the upper surface of the collection box 41. Each input portion 43a is connected to a collection pipe 43b communicating with a storage container 45 as a storage container in which the respective molded products are accumulated.
[0018]
Next, the collecting action of each molded product taken out from the mold will be described.
As shown in FIG. 4, first, the servo motor 23 is driven and controlled to move the left and right traveling bodies 9 to the upper position of the mold, and the servo motor 25 is driven and controlled so that the front and rear traveling bodies 11 are moved to the fixed mold side. Move and wait.
[0019]
When a mold opening completion signal when the molds are opened from the resin molding machine in the above state is input to the molded product take-out machine 1, the servo motor 27 is driven and controlled to lower the upper and lower frames 13 to move the chuck 15 Is moved to a lower position between the opened molds, and then the servo motor 25 is driven and controlled to move the chuck 15 to an advanced position close to the movable mold.
[0020]
In this state, an ejector mechanism (not shown) mounted in the movable mold is operated to project the molded product held in the movable mold toward the chuck 15. At this time, in the molded product, the product portion W and the runner portion are separated by the structure of the mold, and only the respective product portions W are held by the holding members 15 b of the chuck 15. The separated runner part falls by its own weight and is discharged out of the resin molding machine.
[0021]
The servo motor 25 is reversely driven at a timing almost synchronized with the operation timing of the above-described ejector mechanism to return the chuck 15 holding each product part W to the retracted position, and then the servo motor 27 is reversely driven to raise the upper and lower frames 13. And move it to the raised position. At this time, the molded product take-out machine 1 outputs a mold closing signal to the resin molding machine at the timing when the chuck 15 comes out from between the molds, and then executes the molding operation.
[0022]
Next, the servo motor 23 is driven to move the chuck 15 toward the collection device 21. At this time, the electric motor 35 is driven to cause the collection device 21 to jump out of the lower surface of the main body frame 3 to the collection position protruding from the non-projecting standby position to the mold side. When the chuck 15 moves to the collection position, for example, the servomotors 23, 25, and 27 are selectively driven and controlled. First, the product portion W of the molded product held by the first holding member 15b is put into the first collection box 41. After being positioned at the portion 43a, the holding of the product portion W by the first holding member 15b is released and put into the feeding portion 43a.
[0023]
The product part W introduced into the introduction part 43a falls in the recovery pipe 43b by its own weight, and is collected in the first storage container 45 corresponding to the product part W. Similarly, after the servo motors 23, 25, and 27 are selectively driven and controlled, the product portion W of the molded product held by the second holding member 15b is positioned in the input portion 43a of the second collection box 41, and then the second 2 The holding of the product part W by the holding member 15 b is released, the product part W is released into the input part 43 a, and is accumulated in the second storage container 45 corresponding to the product part W.
[0024]
By repeating the above operation, the remaining product parts W are loaded into the loading parts 43a of the corresponding collection boxes 41 and accumulated in the corresponding storage containers 45 to complete the collection work.
[0025]
After the above operation, the servo motors 23, 25, and 27 are driven to return the chuck 15 to the standby position, and wait for the mold opening completion signal when the next molding is completed.
[0026]
In the present embodiment, since the collection device 21 is provided at the end of the main body frame 3 of the molded product take-out machine 1, when collecting a plurality of product parts W in the molded product taken out at the same time, It is possible to prevent the movement distance from becoming long and avoid an increase in the take-out time, and the molded product take-out operation can be performed efficiently. In addition, in the exchanging operation of the mold and the adjusting operation of the injection nozzle in the resin molding machine, the recovery device does not interfere, and therefore these operations can be performed efficiently.
[0027]
The present invention can be modified as follows.
1. In the above description, four collection boxes in the collection apparatus are arranged in a horizontal line, and the chuck 15 is moved in the left-right direction, the front-rear direction, etc., and each product part W held by each holding member is associated with the corresponding collection box. However, when each product part W is held in a cross shape with respect to each holding member, for example, each collection box is arranged so as to match the arrangement state of the holding member. The product parts W may be collected almost simultaneously in a single operation with minimum control of the movement of the chuck.
[0029]
2. In the above description, the product part W in the molded product put in the input part of each recovery box in the recovery apparatus is dropped in its own weight in the recovery pipe and collected in the corresponding storage container to be recovered. Alternatively, the product pipe W that has been sucked into the feeding section by sucking the collecting pipe may be forcibly guided into the container and collected.
[0030]
3. In the above description, each collection box 41 is linearly moved between the standby position on the lower surface of the main body frame 3 and the collection position protruding to the mold side. However, as shown in FIGS. A structure may be adopted in which the collection box is provided so as to swing together and moved to each position.
[0031]
That is, a plurality of collection boxes 41 are mounted on a swing arm 93 that is connected to a swing member 91 such as an electric motor or an air cylinder on the lower surface on the release position side of the main body frame 3 and swings forward (mold side). The fixed frames 95 are rotatably supported so as to always maintain a horizontal state, and each collection box 41 is swung between a standby position and a collection position as the swing arm 93 swings. It may be a structure. At this time, a semicircular guide hole 93a is formed at the end of the swing arm 93, and a guide shaft 97 provided in the frame 95 is slidably supported in the guide hole 93a to thereby support each collection box 41. Can always be moved to the respective positions while maintaining a horizontal state.
[0032]
4). In the above description, each product part W introduced into each input part is recovered directly into the storage container via the recovery pipe. For example, as shown in FIG. A shutter 103 that opens and closes by an operating member 101 such as an air cylinder is provided, and the product part W to be collected is once placed on the closed shutter 103 and cooled until the next product part W is supplied. When the curing is performed and the next product portion W starts to move toward the collection device, the shutter 103 may be opened and the product portion W may be collected in the storage container via the collection pipe.
[0033]
In this case, cooling air is blown to the product portion W placed on the shutter 103 to promote cooling of the product portion W, or the charged product portion W is discharged by blowing ion wind. Also good.
[0034]
【The invention's effect】
The present invention can efficiently perform these operations without interfering with mold replacement operations and various adjustment operations such as injection nozzles in the molding machine. Further, various molded products can be efficiently collected while preventing the movement distance of the chuck on the release position side from increasing and taking time from increasing.
