Pouches, which are widely used in cosmetics, pharmaceuticals, food and household goods, are produced by injecting the contents into a heat-adhesive film, pressing four sides in the form of pouches with heat and pressure, and then cutting the film. Pouch device. Among them, the facility that can implement the shape of the adhesive part and the cut part of the pouch is called a 'shaped pouch device'.

The process of manufacturing the pouch using the shape pouch device includes a film supply process for supplying a heat-adhesive film, a cutting process for cutting the center of the film, a redirection process for changing the direction for laminating the cut film, and processing into a predetermined shape. A pair of hot pressing processes, in which a heater plate and a hydraulic cylinder are attached to the mold plate and the high temperature and high pressure, the film transfer step of transferring the bonded film by a pitch, and the bonded film are prescribed. It consists of a cutting process of cutting into a die-shaped mold cutter to produce a product, and a process of rewinding the residual film. Among them, the hot pressing process for adhering the film at high temperature and high pressure in the shape pouch device is a key process for manufacturing the pouch form by adhering the film.

If a predetermined pressure is not applied during the bonding process in the hot pressing process, since the effective bonding is achieved only under relatively high temperature conditions, the thermal adhesive film forming the material of the pouch is deformed due to excessive heat. Therefore, there is a problem that the production speed falls.

Currently, the heat press apparatus is based on a pressurization method using an air cylinder or a pressurization method using a cam and a hydraulic cylinder.

Among them, the air cylinder method is simple in configuration and the device can be manufactured at a lower price, but it exhibits low compressive force (5 ~ 7 bar, 100 ~ 400 Kgf). Due to the limitation in improving the production speed of pouch products due to impact, it is mainly used in low speed (20 ~ 30 Cycle / min) device or applied in single or two row production facilities.

The method using the cam and hydraulic cylinder has the advantage that it can increase the production speed of the pouch product by using relatively high pressure (10 ~ 30 bar, 400 ~ 700 Kgf).

1 schematically shows a conventional heating and pressing device using a cam and a hydraulic cylinder. Referring to FIG. 1, in the conventional heating and pressing device 10, a force applied from the hydraulic cylinder 40 for applying pressure is primarily applied to the operating lever 20. The force transmitted to the actuating lever 20 is transmitted to the sliding unit 30 having a narrow and long width by changing the direction of the force around the lever hinge 21. The force transmitted to the sliding unit 30 is transmitted to the mold plates 11 facing each other with the heater plate 12 mounted at the rear.

In the conventional heating and pressing device using a hydraulic cylinder and a cam, as shown in Figure 1, because the method of indirectly driving the heating pressing device is used, the first, second operation lever, lever hinge installed in the power transmission unit However, there are disadvantages in that the sliding part parts are frequently damaged by the pressure applied from the hydraulic cylinder.

2 and 3 schematically show a conventional film transfer apparatus.

Referring to these drawings, the conventional film transfer device 50 is a film transfer roller 52 for transferring the adhesive film by a pitch (Pitch), the clutch 60 for driving the same, to stop the rotation of the roller It consists of a brake 61, it consists of a reduction gear 62 for increasing the rotational force through deceleration, a drive gear 63 for connecting the film feed roller shaft 51 and the reduction gear 62. The film transfer device 50 recognizes a mark located on the film as a sensor and transfers the film by one pitch.

However, in the conventional film transfer apparatus, the film transfer position depends on the difference between the processing delay time and the wear and response time of the clutch and brake in the process of processing the sensor signal through the sensor signal → PLC → contactless relay → clutch / brake. Since the deviation occurs, the defect increases, such a deviation is a problem that increases as the production speed increases.

In addition, the axis of the roller for transporting the film positioned between the two is composed of two rotating shafts, one side is a fixed end and the opposite side is composed of a free end for film replacement and position adjustment. Therefore, there is a problem in that the preload between the rollers installed at the fixed end and the rollers installed at the free end occurs, which causes the film to be pulled to one side during film transfer.

Therefore, there is a high need for a technology that can fundamentally solve these problems.

The present invention aims to solve the problems of the prior art as described above and the technical problems that have been requested from the past.

It is characterized by being installed.

Therefore, since the shape pouch apparatus according to the present invention can exhibit a higher pressing force in the heat pressing process and can perform the heat pressing process at a relatively low temperature, the heat-adhesive film for manufacturing the pouch is deformed by heat at a high temperature. It can be prevented, which has an excellent effect of preventing the production rate from falling.
