Description

[Detailed description of the invention] [Purpose of the invention] (Field of industrial application) The present invention is a method of simultaneously fusing a mount such as base paper and a synthetic resin film etc. in packaging bodies called skin packs and blister packs. The present invention also relates to a fusing and cutting device for a seal packaging machine capable of perforating, and a seal packaging machine equipped with the device.

(Prior Art) Packaging bodies called skin packs or blister packs are usually made by placing individual items on a mount such as base paper of a predetermined size, with the vertical direction being the vertical direction and the horizontal direction being the horizontal direction, respectively. This is done by arranging the articles at intervals, covering the articles with a synthetic resin film, and welding the articles using a skin packer.

However, this packaging must be cut into pieces at a retail store, but it is not easy to do so with scissors, etc., and the size of the base paper that serves as the backing for the whole is quite large, so it is difficult to cut the package into pieces at a retail store. Not suitable for use. For this reason, cutting devices such as a roller trimming method have been devised, but they are very expensive because they require preparing a number of molds depending on the size of each package.

Therefore, recently, a cutting workbench has appeared that is suitable for various sizes and is easy to work with (see Japanese Utility Model Publication No. 35437/1983).

(Problem to be solved) Perforation work using such a cutting workbench can be performed extremely easily and efficiently, but as mentioned above, the work of fusing synthetic resin film etc. to the backing paper has never been done before. You must also keep it on.

This process of fusing involves filling a synthetic resin film molded for packaging with the product, fitting it into a wooden mold or metal mold of the same size as the film, and placing a mount coated with adhesive on the surface and heating it before placing it. This was done by pressing and crimping onto a heated hot plate from the mount side.

The inventor proposed that since the perforation work is usually done from the synthetic resin film side, as is the case with the above-mentioned cutting workbench, at this time, heat is applied from the synthetic resin film side at the same time to perform the fusing work. We thought that it would be very convenient if we could do this, and came up with this invention.

[Structure of the idea]

(Means for solving the problem) Therefore, in order to achieve the above purpose, the present invention
The structural requirements of the fusing and cutting device include a vertically movable receiving part having a cutter guide consisting of grooves on the lower surface and a heater receiving part formed in parallel on both sides of the cutter guide, and a receiving part facing this receiving part. It consists of a vertically movable holding part which holds the cutter so that it can run upward along the cutter guide, and heaters are positioned on both sides of the cutter running direction, and the heater is attached to the heater receiver. When the cutter is in contact with the cutter, the cutter is positioned in the cutter receiver.

(Function) To position the package on this fusing and cutting device, first place the molded synthetic resin film face down, fill it with the product, place a mount on top of it, and transport it onto a belt conveyor, etc. This is done by transporting it to the receiving part and holding part of the cutting device.

The package located between the receiving part and the holding part of the fusing and cutting device is held down by the receiving part from above,
It is held by raising the holding part from below. At this time, the heater receiver of the receiving part and the part crimped by the heater of the holding part are fused together, the cutter moves while being located in the cutter guide, and perforation is also performed at the same time.
