Abstract

PROBLEM TO BE SOLVED: To solve the problem that, since the shape of a heating part constituting a weld is a frame-like hot plate, in market requirement of various kinds of commodities, an individual frame-like hot plate or frame-like cutting blade in accordance with each requirement becomes necessary, and further, in a replacement work of the frame-like hot plate following change of a product class, waiting until cooling of a temperature of the frame-like hot plate is required, to thereby require a long time.SOLUTION: In a cardboard film sticking device, rationalization, manpower saving and multi-product production become possible, since preparation of a frame-like hot plate in each size is not required, and a heat-welding processing dimension of a resin film and a plate material to be welded can be set optionally, by halving the frame-like hot plate longitudinally and laterally.SELECTED DRAWING: Figure 1

Description

The present invention relates to a corrugated film pasting apparatus in which a stretchable film made of a urethane resin system having high toughness and stretchability is bonded to a welded plate material made of corrugated cardboard.
In recent years, there has been a corrugated cardboard package business that combines cardboard and urethane film to take advantage of the elasticity and flexibility that are characteristic of urethane films. This is because the product can be stably held by sandwiching the product with a urethane film, the shock absorption is good, the product can be easily packaged, and the conventional cushioning material made of polystyrene foam or the like can be eliminated. In addition, the use of an organic solvent-based adhesive prevents VOCs, resulting in a packaging material with a low environmental load. In particular, relatively light-weight mail-order products are often packed in small quantities and a wide variety of products, and demand is growing steadily.

Conventionally, generally used adhesion of a resin film and a plate material to be welded is known using an organic solvent-based adhesive, thermal welding without using an adhesive, or the like.
Specifically, a film supply unit, a cutting unit that cuts a film to a certain size, a film transport unit, a heating unit that uses a frame-shaped hot plate as an element, and a press unit that includes a pressing plate that moves up and down are provided. After the laminated composite resin film is supplied and cut to a certain size, the laminated composite resin film is transported and placed on a film cradle, and a welded plate material made of predetermined corrugated cardboard is placed on the plate material receiving portion provided on the upper part. This was a thermal welding machine that was mounted and supplied and thermally welded the composite resin film to the plate material to be welded by the welding part (see Patent Document 1).

  However, in the conventional technology, since the shape of the heating portion constituting the welded portion is a frame-shaped hot plate, there are various types of product market demands. In addition, when replacing the frame-shaped hot plate when changing the product type, it takes a long time to wait until the temperature of the frame-shaped hot plate cools down. Was very expensive and became a bottleneck in automating high-mix low-volume production.

  The present invention provides a corrugated cardboard pasting device that can automate multi-product production and can be rationalized and labor-saving because processing dimensions such as the size of the resin film and the welded plate material can be arbitrarily set. it can.

  A feature of the corrugated film pasting apparatus according to the present invention as means for solving the above problems is that a corrugated cardboard having a hollow portion and a stretchable film are stacked in a central portion, and the corrugated cardboard and the stretchable film are bonded around the hollow portion. An apparatus for manufacturing a corrugated cardboard film package, comprising: a corrugated board supply device for supplying a corrugated cardboard having a hollow portion formed in the center in advance; a film supply device for supplying an elastic film; A temporary film fixing device for temporarily fixing the stretchable film conveyed from the film supply device to a predetermined position of the cardboard, and the temporarily fixed cardboard and the stretchable film in a traveling direction. A transverse welding device that is in a transverse direction perpendicular to each other and thermally welds two places before and after the hollow portion; A vertical welding device for simultaneously welding the left and right two parts parallel to the traveling direction and a stacking device for stocking the corrugated film package with the horizontal welding and the vertical welding. It is to be a corrugated cardboard film pasting device.

  The second feature of the present invention is that, in addition to the above feature, the corrugated board has a crease around the hollow portion, and the transverse welding by the transverse welding device and the longitudinal welding by the longitudinal welding device are outside the fold. It is to be a corrugated film pasting device made.

Further, according to a third feature of the present invention, in addition to the above feature, the horizontal welding device and the vertical welding device each include a pair of a horizontal heater unit and a vertical heater unit, and the interval between the heater units can be varied. It is to be a corrugated film sticking device.

According to a fourth aspect of the present invention, there is provided an apparatus for producing a corrugated film package in which corrugated cardboard and an elastic film are stacked and the corrugated cardboard and the elastic film are bonded around the corrugated cardboard. A corrugated cardboard supply device, a film supply device for supplying an elastic film, and a temporary attachment of the elastic film conveyed from the film supply device to a predetermined position of the cardboard conveyed from the cardboard supply device Film temporary tacking device, and the corrugated cardboard and the stretchable film that are temporarily fixed, in the transverse direction perpendicular to the traveling direction and at the same time in the front and rear two locations, or the left and right two locations parallel to the traveling direction. At the same time, there is provided a welding device for heat welding, and an accumulation device for stocking the cardboard film package on which the welding has been performed. It lies in a cardboard film joining apparatus that.

  According to the present invention, the film feeding device and the film tacking device are provided, and the horizontal welding device and the vertical welding device are separately installed, so that the processing dimension setting values of the horizontal welding device and the vertical welding device are individually changed. This eliminates the need to replace the frame-shaped heat plate when changing the product type, enabling the product type to be changed in a short time, and meeting the market needs of Q (quality improvement), C (cost reduction), and D (short delivery time). Corrugated film pasting equipment can be provided to build a production system that can respond.

  Specifically, as the length dimension of the welded part of the finished product, for example, the machining dimension can be set in several stages from 300 mm to 900 mm, and the width between the welded parts can be set. It can be used for many kinds of packaged products with different sheath shapes. In addition, it is possible to save labor and make the system of four people per line into one. In addition, since the frame-like hot plate that has been necessary up to now can be eliminated, a great rationalization can be achieved. As a result, there are significant effects such as cost reduction and ease of delivery due to high-mix low-volume production and demand for large-scale properties.
