Abstract

PURPOSE:To make molding and assembly processes continuous, and to make compact the whole device by arranging an assembling device combining the extraction of shapes while being opposed to a plurality of injection molding machines disposed along a conveyor belt. CONSTITUTION:Shapes 18, 19, 20 are molded by injection molding machines 3 in each work station A, B, C. A conveyor belt 1 is stopped where assembling jigs 2 align with each injection molding machine 3 at the same time. The shapes are extracted by a clamping arm 14 after molds are opened, and placed on the assembling jigs 2. The first shape 18 is molded at the work station A, and placed on the assembling jig 2. The first shape is moved to the next station B by the conveyor belt 1, the second shape 19 is molded, and the second shape is incorporated into the first shape 18. The first and second shapes are moved to the station C, and the third shape 20 is incorporated into the first and second shapes 18, 19, thus manufacturing a product.

Description

[Detailed Description of the Invention] This invention relates to an injection molding assembly device for a product consisting of a plurality of molded products, and the special feature is to assemble each molded product one after another on the spot at the same time as the molding. This relates to injection molding assembly equipment.

2. Description of the Related Art Conventionally, in the production of products consisting of a plurality of molded products, it has been common to mold each molded product using an injection molding machine, and to assemble these molded products sequentially using an automatic assembly device or the like.

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 on the assembly line, space is required to store molded products, and managing inventory parts is time-consuming. It also had the disadvantage of being expensive.

The purpose of the present invention is based on the above-mentioned prior art (in view of problems such as duplication of equipment due to structural constraints of injection molding machines and automatic assembly equipment for products consisting of a plurality of molded products, By arranging the molded product removal/assembly device in opposition to multiple injection molding machines installed at The purpose of the present invention is to provide an injection molding assembly apparatus with a high degree of accuracy.

In accordance with the above object, the present invention has a configuration in which each molded product is molded by each injection molding machine having a mold in which a different molding space is formed, the molded product is taken out, and the molded product is molded at a previous working position. The gist of this is that it is possible to assemble a product by sequentially assembling the molded product onto the transported molded product.

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

In FIGS. 1 and 2, a conveyor belt 1 is endless and is moved by being driven by an appropriate drive source.

A plurality of assembly jigs 2 are fixed to the upper surface of the conveyor belt 1 at regular intervals. And the conveyor belt 1
Along the moving direction, a plurality of injection molding machines 3 are arranged at intervals equal to the arrangement interval of the jigs 2. As shown in FIG. 3, the injection molding machine 3 includes a creation unit 5 that is supported by a column 4 so as to be able to move up and down, a mold clamping cylinder 6 that drives the injection unit 5 up and down, and a mold clamping cylinder 6 that is attached to the lower end of the injection unit 5. It consists of an upper mold 7 and a lower mold 8 placed opposite to the upper mold 7. Different mold engraving spaces are formed in the molds 7.8 of the injection molding a3 at each work station A, B, and C, and each injection molding machine 3 molds a different molded product.

On the other hand, as is clear from FIG. 1, the conveyor belt 1
On the opposite side, 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 and assembly device 10
The clamp consists of a forward and backward cylinder 13 supported by an operating rod 12 of a lifting cylinder 11, a clamp arm 14 that moves forward and backward by the forward and backward cylinder 13, and a clamp 15 attached to the clamp arm 14. Reference numeral 15 is a device that reciprocates between the assembly jig 2 on the conveyor belt 1 and the opened upper and lower molds 1.8.

Please note that the working position is for product removal work.
A product take-out device 16 having the same structure as the molded product take-out/assembly device 10 and a container 17 as a product receiver are provided.

Here, as shown in FIG. 4, three molded products 1B,
19. Regarding the case of molding the product 21 consisting of 20,
Its operation will be explained as follows.

In the above configuration, molded products 1B, 19.
20 is molded.

During this time, the assembly jig 2 on the top surface of the conveyor belt 1
moves to a position aligned with each injection molding machine 3 and stops.

After the molding operation is completed, the mold is opened, the clamp arm 14 of the molded product removal/assembly device 10 is extended, the clamp 15 moves forward, enters between the upper and lower molds 1.8, and is lowered by the lifting cylinder 11 to remove the molded product. Clamp 1B, 19.20. 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 and placed on the assembly jig 2 (FIG. 4(A)). Then, it is transferred to the next work station B by the conveyor belt 1. Here, the second molded product 19 is molded, and this is the J'5B,, ta+c@include ma 6 (*
41o13+, o Next IT, this is work station C
Similarly, the third molded product 20 is transferred to the first,
It is assembled into the second molded product 18, 19, and the assembly of the product 21 is completed (FIG. 4(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 the product receiver is stored in the container 17. .

In addition, in the above-mentioned embodiment, C has been explained as having three molding and assembly work stations, but the number is not limited to this (it is sufficient to correspond to the number of molded products as parts forming the product). Of course.

2, according to the invention IC-, a plurality of injection molding machines, each of which molds a different molded product, are assembled along the moving direction of a conveyor belt fixed at regular intervals, with the assembly jig being fixed at regular intervals. By arranging the molded products at intervals equal to the arrangement spacing of the injection molding machines, and further disposing a molded product take-out and assembly device corresponding to each injection molding machine, each molded product is molded by each injection molding machine, and each molded product is molded by each injection molding machine. Extracting molded products and assembling equipmentff
A" is taken out from the injection molding machine, placed on the assembly jig of the conveyor belt), incorporated into the molded product molded in step n11, and then sequentially transferred to complete the product. By integrating the molding process and the assembly process, it is possible to prevent duplication of equipment and has the excellent effect of not requiring a large space.

Since the assembly work is carried out at the same time as the Moshi C1 molding work, there is no need to stock molded products as parts, there is no need for storage space for molded products, and there is an effect that the labor of stock management can be saved. There is also.

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