Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an injection molding assembly apparatus for products consisting of a plurality of molded products, and in particular, an injection molding assembly device that assembles each molded product sequentially on the spot at the same time as the molded products are molded. This relates to molding and assembly equipment.

Conventionally, when manufacturing products consisting of multiple molded products, the common method was to mold each molded product using an injection molding machine, and then assemble these molded products one after another using automatic assembly equipment, etc. .

However, in the above-mentioned conventional technology, since the process is divided into two processes, a molding process and an assembly process, there is a drawback that the equipment is duplicated, the overall size becomes large, and a large space is required. In addition, since molding and assembly are not continuous,
Molded products must be stocked during the assembly line, space is required to store the molded products, and managing inventory parts is time consuming.

The purpose of the present invention is to solve problems such as duplication of equipment due to structural limitations of injection molding machines and automatic assembly equipment for products consisting of a plurality of molded products based on the above-mentioned prior art, and to solve the problem of duplication of equipment, etc. By arranging the molded product ejecting and assembling device in opposition to the multiple injection molding machines installed, the above-mentioned drawbacks are eliminated, and the entire device is compact, making it possible to perform extremely efficient molding and assembling operations. The present invention aims to provide a molding and assembly device.

The configuration of the present invention in accordance with the above object is to mold each molded product using each injection molding machine having a mold in which a different molding space is formed, take out the molded product, and mold it at a previous work position. The gist of this is that the product can be assembled by sequentially assembling the molded product onto the molded product that has been molded and transported.

Next, embodiments of the present invention will be described below with reference to the drawings.

In Figures 1 and 2, conveyor belt 1
is endless and moves by being driven by an appropriate driving source. On the upper surface of the conveyor belt 1,
A plurality of assembly jigs 2 are fixed at regular intervals.
A plurality of injection molding machines 3 are arranged along the moving direction of the conveyor belt 1 at intervals equal to the arrangement interval of the jigs 2. As shown in FIG. 3, the injection molding machine 3 includes an injection unit 5 that is supported by a column 4 so as to be able to rise and fall freely, and
a mold clamping cylinder 6 that drives the injection unit up and down; an upper frame 7 attached to the lower end of the injection unit 5;
and a lower mold 8 disposed opposite to each other.
Different mold engraving spaces are formed in the molds 7 and 8 of the injection molding machines 3 at the work stations A, B, and C, and each injection molding machine 3 molds different molded products.

On the other hand, as is clear from FIG. 1, on the opposite side of the conveyor belt 1, a molded product removal/assembly device 10 is disposed at a position facing the injection molding machine 3. As shown in FIG. 3, the molded product removal/assembly device 10 includes a forward and backward cylinder 13 supported by an operating rod 12 of an elevating cylinder 11, and a clamp that moves forward and backward by the forward and backward cylinder 13. It consists of an arm 14 and a clamp 15 attached to the clamp arm 14,
Clamp 15 is assembly jig 2 on conveyor belt 1
The mold reciprocates between the opened upper and lower molds 7 and 8.

The work position D is for product removal work, and includes a product removal device 16 having the same structure as the molded product removal and assembly device 10, and a product receiving container 1.
7 are arranged.

Here, the operation for molding a product 21 consisting of three molded products 18, 19, and 20 as shown in FIG. 4 will be described as follows.

In the above configuration, each work station A,
Molded products 18, 19, and 20 are formed by the injection molding machines 3 in B and C, respectively.

During this time, the conveyor belt 1 moves to a position where the assembly jig 2 on its upper surface aligns with each injection molding machine 3 and stops.

After the molding operation is completed, the mold is opened, and the clamp arm 14 of the molded product removal/assembly device 10 is extended and the clamp 15 is moved forward and entered between the upper and lower molds 7 and 8, and then lowered by the lifting cylinder 11. Clamp the molded products 18, 19, and 20. Then, after rising again, it retreats and stops at a position above the assembly jig 2 of the conveyor belt 1. Next, the clamp 15 is lowered and the molded product is placed on the assembly jig 2.

As shown in FIG. 4, the first molded product 18 is molded at the work station A.
It is placed on the assembly jig 2 (FIG. 4A). and,
It is transferred to the next work station B by the conveyor belt 1. Here, the second molded product 19 is molded and assembled into the first molded product 18 on the assembly jig 2 (FIG. 4B). This is then transferred to the work station C, and similarly, the third molded product 20 is added to the first and second molded products 18, 1.
9 to complete the assembly of product 21 (4th
Figure C).

The molding work and assembly work at each of the work stations A, B, and C are performed simultaneously and synchronously.

The product 21 assembled in accordance with the molding operation in this way is taken out from above the assembly jig 2 by the product take-out device 16 at the next product take-out work station D, and stored in the product receiving container 17. Ru.

In the above embodiment, the number of molding and assembly work stations is explained as three, but the number is not limited to this, and it goes without saying that the number of molding and assembly work stations may be set in accordance with the number of molded products as parts forming the product. It is.

As described above, according to the present invention, a plurality of injection molding machines each molding a different molded product are installed along the moving direction of a conveyor belt to which assembly jigs are fixed at regular intervals. are arranged at equal intervals, and a molded product take-out/assembly device is further provided corresponding to each injection molding machine, so that each molded product is molded by each injection molding machine, and the molded product is The product is taken out of the injection molding machine by a mold takeout and assembly device, placed on an assembly jig on a conveyor belt, and incorporated into the molded product molded in the previous stage, and then sequentially transferred. Since the product can be completed in one step, the molding process and assembly process are integrated, which has the excellent effect of preventing duplication of equipment and not requiring a large space.

Since the assembly work is performed simultaneously with the molding work, there is no need to stock molded products as parts, no storage space is required for molded products, and there is also the effect that the effort of inventory management can be saved.

In addition, since the molding work and molded product removal/assembly work are performed simultaneously and synchronously through each work station, there is no waste in the overall work at each work station, and the work can be carried out efficiently. It also has the advantage of being able to
