BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insert positioning device, and more particularly to a new improvement for surely positioning an insert product at a designated position.

[0002]

2. Description of the Related 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 prevention 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, the restricting piece 6a The piece 6a is raised. After that, the feed claw 7a is moved forward, and the end portion 4a of the linear feeder 4 (constituting a part of the positioning jig 7).
Insert the tip of the insert 3 into contact with the insert 3
Complete the positioning. Then, the arm of the automatic machine (not shown) receives the positioned insert product 3,
This is placed in a mold (not shown) of the molding machine, and insert molding is started.

[0003]

Since the conventional insert positioning device 2 is constructed as described above, the following problems exist. That is, insert 3
In the case of a simple shape such as a cylindrical shape, the conventional insert positioning device 2 described above was also able to effectively position the insert. However, when the insert 3 has a complicated special shape, the feed claw 7a is simply used.
Even if the insert 3 is moved forward, the positioning may not be performed reliably. Further, in particular, when the insert product has a plate shape, unless the linear feeder 4 is inclined at a predetermined angle, the insert products that are continuously fed may be shaken or overlapped, and a situation in which they are not aligned and advanced may occur. is there. Therefore, if the subsequent insert receiving base 5 is tilted and the insert product 3 is fed onto the tilted insert receiving base 5, even if the positioning jig 7 is arranged on the insert receiving base 5, the insert product 3 is aligned with the insert product 3. Jig 7
There was a case where it was misaligned and accurate positioning was not performed.
It is no exaggeration to say that nearly 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, a hole for evacuation is formed in the insert cradle 5 at a place where the insert 3 is placed, and an attempt has been made so that the position of the insert does not shift at this portion. No stable positioning of 3 could be achieved.

The present invention has been made to solve the above problems, and an object thereof is to provide an insert positioning device for surely positioning an insert product at a designated position.

[0005]

An insert positioning device according to the present invention supplies an insert product sent from a parts feeder to an insert cradle located downstream of the straight feeder through a guide rail of the straight feeder. In an insert positioning device configured to move the insert cradle holding the insert product to another position, a positioning jig provided on the insert cradle and having a positioning surface, and provided on the insert cradle And a magnet that is superposed on the alignment jig, and a sensor that is provided on the insert cradle and detects the positioning of the insert product. The shape of the alignment surface contacts the tip of the insert product. In addition, it is formed in a shape that follows the tip portion.

More specifically, the alignment surface is formed in a dogleg shape.

[0007]

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

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the insert positioning device according to the present invention will be described in detail below with reference to the drawings. In addition, the same or equivalent portions as those of the conventional example will be described using the same reference numerals.

FIG. 1 shows an automatic insert-positioning and positioning apparatus A, in which a straight feeder 4 is provided at the insert outlet of a parts feeder 1, and an insert-positioning apparatus 2 of the present invention is arranged at the tip of the straight feeder 4. ing.
As shown in FIG. 2, the straight-moving 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 protrusion on the bottom surface of the thin plate-shaped insert 3 which is a magnetic body. It has 4a and 4b. These guide rails 4a and 4b are arranged in the longitudinal direction on the upper surface of the linear feeder 4 and are parallel to each other. Above the guide rails 4a and 4b, the insert 3
However, a floating prevention plate 8 is provided so as not to overlap due to vibration and not to jump up from the straight advance 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. This insert cradle 5
A positioning jig 7 for positioning the insert product 3 is arranged on the transport surface 5a of. At the upstream side position of the positioning jig 7, a positioning surface having substantially the same shape (a dogleg shape in this embodiment) following the shape of the tip 3a of the insert 3 sent from the straight feeder 4 is provided. 7b
Are formed. A permanent magnet 9 (or an electromagnetic magnet may be used) 9 is arranged immediately downstream of the alignment surface 7b on the downstream side. This permanent magnet 9
Are fixed so as to be embedded in the insert cradle 5 in a state of overlapping with the position adjusting jig 7 on the back surface of the position adjusting jig 7.

Alignment surface 7 of the insert cradle 5
A sensor 10 for detecting and confirming that the positioning of the insert 3 is performed is arranged on the upstream side immediately before b. The operation of the sensor 10 promotes the escape of the insert cradle 5 and moves the insert cradle 5 to another position that 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, are aligned continuously, and are fed to the linear feeder 4. Then, the insert 3 is sent to the downstream side in an inclined state along the guide rails 4a and 4b of the straight 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 3 is forcibly pulled downstream by the magnet 9 arranged on the downstream side of the insert cradle 5.

While being affected by the magnet 9,
The insert 3 is carried to the alignment surface 7b of the alignment jig 7 immediately before the magnet 9, and then the alignment surface 7b and the tip 3a of the insert 3 come into contact with each other,
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 3 is completed, a positioning completion signal is issued by the sensor 10, and based on this, an automatic machine (not shown) in the next step facilitates the delivery of the insert 3. Move the insert cradle 5 to the position. 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 forming machine, and insert molding is started. It

It should be noted that the insert cradle 5 is automatically driven by an automatic machine.
After the insert product 3 is carried out from the insert cradle 5, the insert pedestal 5 returns to the initial position, and the next insert product 3 is prepared for positioning.

[0016]

Since the insert positioning device according to the present invention is constructed 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 toward the alignment jig by the magnet toward the downstream side, and the alignment surface and the tip of the insert product are separated. Even if they are aligned and forcibly positioned by the positioning jig, and the positioning state between the positioning jig and the insert product is reliably maintained by the magnetic force of the magnet even after the positioning, the insert product can be reliably placed at the specified position. It is possible to perform positioning, and it is possible to improve the accuracy of delivering the insert product to the automatic machine on the downstream side of the insert positioning device, and as a result, it is possible to ensure insert molding.
