[Prior Art]

 FIG. 4 shows a conventional insert positioning device 2 connected to a parts feeder 1. The insert product 3 continuously sent out from the parts feeder 1 is sent to the insert cradle 5 of the positioning device 2 along the linear feeder 4. The leading insert product 3 sent onto the insert receiving table 5 is individually held by the downward movement of the restriction piece 6a of the escape stopping device 6. After the insert piece 3 is held by the restricting piece 6a, the feed claw 7a of the positioning jig 7 that moves in the longitudinal direction along the insert receiving base 5 is arranged at the rear end of the insert piece 3 and at the same time. Then, the restriction piece 6a is raised. After that, the feed claw 7a is moved forward, and the tip of the insert 3 is brought into contact with the end 4a of the linear feeder 4 (which constitutes a part of the positioning jig 7) to position the insert 3. To complete. After that, the arm of the automatic machine (not shown) receives the positioned insert product 3, places it in the mold (not shown) of the molding machine, and insert molding is started.

[Problems to be solved by the device]

 The conventional insert positioning device 2 has the following problems because it is configured as described above. That is, when the insert 3 has a simple shape such as a cylindrical shape, the insert positioning device 2 described above could effectively position the insert. However, in the case where the insert 3 has a complicated special shape, the positioning may not be surely performed even if the insert 3 is simply advanced by the feed claw 7a. Further, particularly when the insert product has a plate shape, unless the linear feeder 4 is tilted at a predetermined angle, the insert products that are continuously fed may be shaken or overlapped and may not be aligned and advanced. There is Therefore, if the insert pedestal 5 that follows is tilted and the insert product 3 is fed onto the tilted insert pedestal 5, even if the alignment jig 7 is arranged on the insert pedestal 5, the insert product 3 There was a case where the positioning jig 7 and the positioning jig 7 were misaligned and accurate positioning was not performed. It is no exaggeration to say that about 90% of the success or failure of automation depends on how accurately the inserter is positioned by eliminating the deviation. Therefore, in order to avoid such a situation, we made a hole in the insert cradle 5 at the place where the insert 3 rests, and tried to make sure that the position of the insert did not shift in this part. It was not possible to achieve stable positioning of product 3.

The present invention has been made to solve the above problems, and it is an object of the present invention to provide an insert positioning device that reliably positions an insert product at a specified position.

[0005]

[Means for Solving the Problems]

 The insert positioning device according to the present invention positions the insert product sent from the parts feeder on the upstream side of the automatic machine. A magnet is arranged on the table.

More specifically, the configuration is such that the magnet is arranged immediately downstream of the alignment surface of the alignment jig.

More specifically, the positioning jig is arranged on the insert pedestal.

[0008]

In the insert positioning device according to the present invention, the insert product sent out from the parts feeder is conveyed to the insert cradle, and the insert product on the insert cradle is pulled by the magnet to the downstream side, and Since the insert product is positioned by the positioning jig while maintaining the pulling state, the insert product continues to be pulled before it comes into contact with the alignment jig, and even after the contact with the alignment jig, The alignment between the alignment jig and the insert is maintained. Therefore, the accuracy of delivering the insert product to the automatic machine downstream of the insert positioning device is improved.

【Example】

 Hereinafter, a preferred embodiment of an insert positioning device according to the present invention will be described in detail with reference to the drawings. It should be noted that the same or equivalent portions as those of the conventional example will be described using the same reference numerals.

FIG. 1 shows an insert product automatic feed positioning device A, in which a straight feeder 4 is provided at the insert product outlet of the parts feeder 1, and the insert positioning device 2 of the present invention is provided at the tip of the straight feeder 4. It is arranged. As shown in FIG. 2, the straight feeder 4 is arranged so as to be inclined with respect to the installation surface B of the apparatus, and is also engaged with a projection on the bottom surface of the thin plate-shaped insert 3 which is a magnetic body. 4a and 4b. The guide rails 4a and 4b are arranged in the longitudinal direction on the upper surface of the straight feeder 4 and are parallel to each other. A floating prevention plate 8 is provided above the guide rails 4a and 4b so that the insert 3 does not overlap due to vibration and does not bounce up from the linear feeder 4.

Next, as shown in FIG. 3, the insert positioning device 2 is provided with an insert cradle 5 on which the insert 3 is placed. A positioning jig 7 for positioning the insert 3 is arranged on the carrying surface 5a of the insert receiving base 5. On the upstream side of the positioning jig 7, there is formed a positioning surface 7b having substantially the same shape as the shape of the tip portion 3a of the insert 3 sent from the straight feeder 4. Immediately after the alignment surface 7b, a permanent magnet (or an electromagnetic magnet may be used) 9 is arranged on the downstream side. The permanent magnet 9 is fixed on the bottom surface of the positioning jig 7 so as to be embedded in the insert receiving base 5.

A sensor 10 for confirming that the insert 3 has been positioned is arranged on the upstream side immediately before the alignment surface 7b of the insert holder 5. The operation of the sensor 10 prompts the insert cradle 5 to escape, and moves the insert cradle 5 to a position where it facilitates the delivery of the insert 3 by an automatic machine (not shown) in the next step.

The operation will be described below based on the above-mentioned configuration. The inserts 3 placed in the parts feeder 1 are aligned by vibration, continuously aligned and delivered to the immediately preceding feeder 3. Then, the insert 3 is sent to the downstream side in an inclined state along the guide rails 4a and 4b of the linear feeder 4. Then, the leading insert product 3 is placed on the insert cradle 5 located on the most downstream side of the automatic insert product supply positioning device A. At that time, the insert 9 is forcibly pulled downstream by the magnet 9 arranged on the downstream side of the insert receiving base 5.

Then, while being affected by the magnet 9, the insert product 3 is carried to the alignment surface 7b of the alignment jig 7 immediately in front of the magnet 9, and then the alignment surface 7b and the tip of the insert product 3 are moved. The parts 3a come into contact with each other, and the positioning of the insert 3 is completed. Since the insert 3 is held while being affected by the magnet 9, the insert 3 is positioned without displacement even if some vibration occurs.

At the same time when the positioning of the insert product 3 is completed, a positioning completion signal is issued by the sensor 10, and based on that, the delivery of the insert product 3 by an automatic machine (not shown) in the next step is carried out. Move the insert cradle 5 to a position that facilitates it. After that, the positioned insert 3 is chucked by, for example, an arm (not shown) of an automatic machine, the insert 3 is placed in a mold (not shown) of the molding machine, and insert molding is started. It

After the insert product 5 is carried out of the insert cradle 5 by the automatic machine, the insert cradle 5 returns to the initial position, and the positioning of the next insert product 5 is prepared.

[0017]

[Effect of the device]

 Since the insert positioning device according to the present invention is configured as described above, the following effects can be obtained. That is, by arranging the magnet on the insert cradle, the insert product on the insert cradle is pulled downstream by the magnet toward the alignment jig and forcibly positioned by the alignment jig. Even after the positioning, the positioning state between the positioning jig and the insert product is reliably maintained by the magnetic force of the magnet, so the insert product can be reliably positioned at the specified position, and the insert positioning device can be positioned downstream. It is possible to improve the accuracy of delivering the insert product to the automatic machine on the side, and as a result, insert molding can be ensured.
