2. Description of the Related Art Among various hangers, there is one in which a hook made of metal or the like is press-fitted and attached to a hanger body made of synthetic resin or the like by an injection molding machine. As a hanger used in the manufacture of such a hanger, conventionally, the hanger body and the hook are individually held individually in a jig or the like by hand, and by driving a pressure cylinder, a motor or the like, for example, on the hook side. There was a hook press-fitting machine in which a hook was press-fitted into the hanger body by sliding a jig or the like.

[0003]

However, in the conventional hook press-fitting machine, since the hanger body and the hook are held by a jig or the like by a worker's manual work, respectively, it is very troublesome. It requires work, and automation was desired.

[0004] Generally, an operator stores a certain amount of the hanger body formed by an injection molding machine and then press-fits the hook. However, if the hanger body is stored in this way, , Not only the extra space for storing the hanger body is required, but also the hanger body is completely hardened, and even if the hook is pressed into the completely hardened hanger body, it is not firmly fixed. In some cases, it became a defective product. To prevent this, the hook must be pressed in before the hanger body has completely hardened.
Depending on the operation of the injection molding machine, the worker must press the hooks into the hanger body immediately after molding, one after another. However, when an operator works on the injection molding machine as described above, the worker cannot perform other work, and the working efficiency becomes very poor. For this reason, automation of the work of press-fitting the hook into the hanger body has been desired.

By the way, in recent years, a plurality of hanger bodies are simultaneously molded by an injection molding machine in response to a demand for improvement in production capacity. In order to automatically press fit the hooks into the plurality of hanger bodies simultaneously molded in this manner, for example, a device that conveys a large number of parts one by one with their directions aligned, a so-called parts feeder, etc. is included. However, it is expected that considerably complicated and large-scale equipment will be required. In particular, for small parts such as hooks, parts feeders and the like can be stored in a small size, but for parts that are large and difficult to handle, such as the hanger body,
Naturally, the parts feeder etc. will also become large and complicated.
Therefore, the inventors of the present invention have devised how to automatically press fit the hooks into the plurality of hanger bodies simultaneously molded from the injection molding machine by using a simple and small device. The invention was completed.

The present invention has been made in view of the above circumstances, and an object of the present invention is to automatically and sequentially press fit hooks into a plurality of hanger bodies simultaneously molded by an injection molding machine. It is an object of the present invention to provide a hook automatic press-fitting machine for a hanger having a simple structure in which the press-fitted hook can be firmly fixed to the hanger body.

[0007]

The means adopted by the present invention for solving the above problems will be described with reference to the reference numerals used in the drawings. "A plurality of hanger bodies simultaneously molded by an injection molding machine will be described. 1 has a holding member 11 for individually holding each on the same circumference, supports the holding member 11 rotatably around the circumference, and holds the hanger body 1 from the upright state to the overturned state. The holding device 10 tiltably supported to the hook 2 and the hooks 2 conveyed from a parts feeder for aligning a plurality of hooks 2 and individually conveying the hooks 2.
And a hook press-fitting device 20 that press-fits the end of the hanger main body 1 held by the holding member 11 in a fall state so that the end thereof faces the hanger main body 1. It is the hook automatic press-fitting machine 100 "of the hanger 3.

[0008]

The hook automatic press-fitting machine 100 for the hanger 3 according to the present invention having the above-described structure operates as follows.

First, the holding device 10 has a holding member 11 for individually holding a plurality of hanger bodies 1 simultaneously molded by an injection molding machine in an upright state. It is supported so that it can tilt to fall.

On the other hand, the hook press-fitting device 20 has the hanger body 1 in which the hook 2 conveyed from the parts feeder is held by the holding member 11 in the tilted state of the holding device 10.
One of the hooks 2 is held so that its ends face each other, and the held ends of the hooks 2 face each other.
It is to be pressed into. Therefore, when the holding member 11 of the holding device 10 is in the tilted state, the hook 2 is press-fitted into one of the plurality of hanger main bodies 1 held by the holding member 11.

By the way, the holding member 11 of the holding device 10
Holds a plurality of hanger bodies 1 on the same circumference, and is rotatably supported on the circumference of the circumference. Therefore, even the hanger body 1 other than the hanger body 1 held at the position where the hook 2 is press-fitted as described above is held at the position where the hook 2 is press-fitted by rotating the holding member 11. Will be. Therefore, if the holding member 11 is rotated and the hook 2 is sequentially press-fitted into the hanger body 1 held at the position where the hook 2 is press-fitted,
The hooks 2 can be attached to all of the plurality of hanger bodies 1 held by the holding device 10.

The hanger body 1 immediately after being molded by the injection molding machine is sequentially held by the holding device 1 according to the manufacture thereof.
If the hook 2 is press-fitted while being held at 0, the hook 2 will be press-fitted into the hanger body 1 before being cured, and the hook 2 will be firmly fixed to the hanger body 1.
