Method and device for squeezing viscous material

Abstract

A squeezing method and a squeezing device capable of safely squeezing contents of viscous material with less residue and waste, comprising the steps of squeezing the viscous material (21) by holding and pressing an unsealed package body (22) by two sheets of plate-like members (2) and (3) in the state of the package body (22) disposed between the plate-like members (2) and (3) rotatably connected to each other. The squeezing device (1) comprises a support plate (2) supporting the package body (22) and a pressing plate (3) having one end rotatably fitted to the support plate (2), and is formed so that the package body (22) supported by the support plate (2) is held and pressed between the support plate (2) and the pressing plate (3). A roller (10) pressing the pressing plate (3) against the support plate (2) is desirably installed in the squeezing device (1). Also, guide mechanisms (4) such as rack gears (4a) for guiding the roller (10) are desirably installed on both sides of the support plate (2).

Description

technical field [0001] The present invention relates to an extrusion method and an extrusion device for extruding a viscous body from a package containing the viscous body in a flexible packaging container. Background technique [0002] In the past, as a device for extruding viscous bodies such as adhesives and inks filled in flexible packaging containers such as bags (small bags) and tubes, from the above-mentioned packaging containers, for example, Japanese Patent No. According to the description in Publication No. 2001-225816, there is known a bag that is placed on the abutment by a roller from above, and the roller travels from the bottom of the bag to the opening, thereby releasing the contents. (Liquid substance) A device with a structure that squeezes out from the opening of the bag. [0003] However, in the above-mentioned extruding device, when the soft bag body is pushed by the roller, the bag body tends to be wrinkled. In this way, the liquid substance adhering ...

AI Technical Summary

Problems solved by technology

Once the roller is dirty, the roller becomes easy to slide, etc., affecting the continuation of work, and it is very troublesome to clean the roller every time

[0006] like Figure 5 As shown, when the content is a high-viscosity liquid, when the bag body 20 is clamped and pressed by the base T and the roller R, the opening 20c of the bag body 20 is pushed up and becomes an upward state, sometimes Unable to smoothly drop the liquid 21 into the receiving container

Not only is the liquid 21 wasted, but also the extrusion device will be dirty

In order to suppress the upward push of the bag body 20, if the vicinity of the opening 20c of the bag body 20 is pressed by hand, there is a risk that fingers, etc. will be caught by the roller R.

In addition, there is also the problem that the extrusion force is locally concentrated and the bag body 20 is broken.
