Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a synthetic resin bag with a zipper.

[0002]

2. Description of the Related Art Conventionally, inserting a slider of this type of bag has been done manually.

Therefore, the labor cost occupies a large proportion of the production cost, which requires much time and labor.

[0004]

SUMMARY OF THE INVENTION The present invention has been successfully researched as to whether or not all processing can be carried out by automation and succeeded in its development.

Until now, the insertion of the slider was considered to be performed manually, but if the process of this part could be automated, the automation of the other parts could be facilitated.

[0006] The problem of how to operate the slider on each of the bags is a very serious problem and also a difficult problem.

It has been considered to insert the slider in advance of the chuck, but this is also a very difficult problem when it comes to automating putting the slider in advance. Further, even if it is put in, there are various problems in making it the process of automatic processing.

The present invention was developed in view of the above matters.

[0009]

In order to achieve the above-mentioned objects, the present invention provides the following method.

During the process of producing a synthetic resin bag with a chuck by a mechanical flow operation, the flow of the line is temporarily stopped to release the fitting of the chuck, and the released portion is connected to the line. It is preferable to make a cut in a direction perpendicular to the flow direction, immediately after making this cut, position a slider at this portion, restore the flow, insert the slider into the chuck, and manufacture. As a process, the male and female chucks are delivered to the line in a fitted state, and in the next step, the upper and lower cloths of the bag are piled on the upper and lower sides of the male and female chucks simultaneously from the upper and lower sides of the line. In this state, the upper and lower fabrics and the male and female chucks are fused, and in the next step,
The male and female chuck parts of the article thus configured are released from the chuck fitting at appropriate intervals, and the released parts are cut in a direction orthogonal to the flow direction of the conveyor. Immediately after making the incision, insert a slider from this part, and in the next step, perform the entire process by fusing the incision part into a desired bag shape, etc. It is a method characterized by that.

[0011]

Since the present invention is a method as described above, it does not require manpower and time as in the prior art, and almost all steps can be processed by a mechanical flow process. It is possible to provide an accurate product which has a great effect, is safe to work, and is inexpensive and accurate. The order of the steps for making the cuts is not limited.

[0012]

Next, the present invention will be described with reference to the drawings. The roll 2 wound with the male and female chucks 1 fitted together is installed at the tip of the apparatus A, and the chuck 1 is delivered from the roll 2 onto the line in the next step. , The cloths 5 and 6 on the front and back of the bag are fed from the rolls 3 and 4 provided above and below the line so as to be piled up and down on the male and female chucks 1 at the same time. The male and female chucks 1 are fused together, and in the next step, the flow of the line is temporarily stopped, and the male and female chuck 1 portions of the article configured as described above are placed at appropriate intervals. The fitting 7 is released, and the cut 7 is formed in a direction orthogonal to the flow direction of the released line.
Immediately after inserting the notch 7, the guide tool is positioned at a position corresponding to this portion, the slider 8 is held by this, the flow is restored again, and the slider 8 is inserted from this portion, This is characterized in that, in the next step, the cut 7 is used as a guide to melt into a desired bag mold 9 and the like, and all of these steps are performed by a flow work.

In the above steps, the device A may be composed of a part or a part which is conventionally used. For example, the robot B for supplying the slider 8 and transferring it to a predetermined position. Etc. or a device C for fusing,
It is possible to provide a reasonable and inexpensive product that can be reasonably processed by using D and the like that have been conventionally used and those that have been used in other fields.

[0014]

Since the present invention is the method as described above,
It does not require labor and time as in the past,
Almost all strokes can be processed by mechanical flow strokes, which has a great effect that could not be considered in the past.
We can provide safe and inexpensive products.
