Abstract

PURPOSE:To uniformly compress air-permeable bulky material such as wadding in a short time by compressing the air-permeable bulky material by belts having a squeezing mechanism. CONSTITUTION:When elastic and bulky material 7 such as wadding, which is wound up in a roll shape, or one wrapped by a film bag made of air- unpermeable synthetic resin as required, is to be compressed, the air-permeable bulky material 7 is rested on a plate 6 placed between belts 4 and 4' at the upper section of a squeezing mechanism 5, the end section of upper section covers 2 and 2' above the belts 4 and 4' are closed, and the squeezing mechanism 5 holding the belts 4 and 4' is then moved up thereafter. By this constitution, the air-permeable bulky material 7 is compressed, the compressed bulky material 7 is then taken out of a compression device 1, and it is wrapped by a bag and the like thereafter. This constitution thereby allows the air-permeable bulky material 7 to be uniformly compressed toward the center direction, and also concurrently, enables time required to be thereby shortened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compression method for uniformly reducing the volume of a breathable bulky material by uniformly compressing a breathable bulky material such as cotton wool in a short time. Device and compressed breathable bulk material.

[0002]

2. Description of the Related Art As a conventional method for reducing the volume by compression, a suction hose is inserted into an impermeable bag made of polyethylene or the like into which a breathable bulky material such as rolled cotton is put. Although there is a method of compressing by suctioning, it takes a long time to compress, and since the shape of the compressed product becomes a flat shape, quality damage is great and recovery is delayed. In addition, since the appearance was inferior, there were few products that could be compressed. Also, as another method,
There is compression packaging with steel pipes. This is a steel pipe machine that shrinks the concentric circle by inserting the roll-filled padding into the inside of the concentric circle made up of about 6 steel pipes that are concentrically and vertically attached to the disc. This is a method in which a bag made of polyethylene or the like is inserted from the outside of a concentric steel pipe after it is pressed against the surface of the product, and then the compressed padding is pushed into the bag and taken out. However, there is a problem that the contact portion between the product and the pipe is easily damaged, and the thickness of the product after recovery is different because the compression is not uniform in the central direction.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to solve the problems such as product damage, shape after compression, and time required for compression, which are caused by these conventional methods.

[0004]

SUMMARY OF THE INVENTION The invention of the present application is one in which a breathable bulky material such as roll-shaped cotton wool is uniformly compressed by a belt having a squeezing mechanism, and preferably the roll is pre-rolled. This is a method of compressing a bulky elastic padded cotton that is wound into a shape and packaged in a bag of a film made of an impermeable synthetic resin, if necessary.
The compression method is, for example, as shown in FIG.
2'and the lower bar 3, 3'fixed at both ends, two wide belts 4 and 4'having substantially the same length, the upper bar 2,
2'opening and closing mechanism, a narrowing mechanism 5 for sandwiching the two belts 4 and 4 ', an elevating mechanism for moving the narrowing mechanism 5 up and down, and a plate 6 provided on the upper part of the narrowing mechanism 5 It is performed by the compressing device 1 for the bulky material. The compression according to the invention of the present application is to place the breathable bulky material 7 on the plate 6 provided between the belts 4 and 4'above the squeezing mechanism 5 in FIG. After closing the ends of 2, 2 ', the belt 4,
The air permeable bulky material 7 such as a compressed roll-like material is formed by moving the narrowing mechanism 5 sandwiching 4'to the upper side.
Is taken out from the compression device 1 and then wrapped in a bag or the like.

Examples of breathable bulky materials to be compressed include fiber webs, paddings, filters, glass wool, breathable foams, etc., and are suitable for roll-shaped paddings.

As a material for preliminarily packaging the air-permeable bulky material, a sheet such as a film or paper, a bag or a string can be used, but a non-air-permeable synthetic resin film such as polyethylene or polypropylene is preferable, and both ends or one end are A cylindrical shape having an opening is preferable.

As a material for the belts 4 and 4 ', a non-stretchable material is preferable, and a plastic sheet, canvas,
A net, a bronze mesh, a plastic mesh coated with urethane rubber, polyurethane, vinyl chloride or the like is used, but a plastic mesh coated with a polyurethane resin is particularly preferable. The outer surface of the belt when it is squeezed may be treated with Teflon or the like.

The number of belts may be one or plural. In the case of two sheets, the belts 4 and 4 ′ may have the same length or different lengths. Further, it is preferable that the upper bars 2, 2 ′ have the same height when the belt is squeezed. The height of the top bars 2, 2'is to facilitate placing the breathable bulk material on the plate 6.
It is preferable to lower the height of one of the upper bars 2, 2 '.

The material of the plate 6 is preferably a material having a certain degree of rigidity and flexibility, and plastic, metal, canvas, cardboard or the like is used, and a soft vinyl chloride sheet is particularly preferable. It suffices that the plate is concave, and it is more preferable that the plate is close to the arc of the final product.

The narrowing mechanism 5 may be movable up and down or may be fixed. For example, it can be configured by two rolls, two belts 4 and 4'are sandwiched between the rolls, and the rolls are moved up and down by an elevating mechanism to squeeze the two belts, and the ventilation placed between them. The bulky material is compressed into a roll. The narrowing mechanism can be stopped at any position according to the size or compression ratio of the air-permeable bulky material.

As another example, one end of the squeezing mechanism and one of the belts passed through the squeezing mechanism is fixed, the belt is laid along the circumference of the roll-like air-permeable bulky material, and then the squeezing mechanism is passed again. The belt may be squeezed by unwinding the other end of the belt, and the air-permeable bulky material placed between them may be uniformly compressed in a roll shape.

EXAMPLES The invention of the present application will be specifically described below by using a cotton pad as a breathable bulk material. Example 1 First, the compression device is in the initial state shown in FIG. Then, as shown in FIG. 3, a polyethylene bag (not shown) having one end opened and a diameter of 950 mm × width of 1600 m
The roll-shaped padding 7 of m is placed on the plate 6 of the compression device from between the upper bars 2, 2 ', and the upper bars 2, 2'are moved and closed in the direction of the arrow as shown in FIG. . Then,
As shown by the arrow in FIG. 5, the squeezing mechanism 5 is moved upward to move the roll-shaped padding 7 on the plate 6 into the belt 4,
Compress while squeezing at 4 '. In this way, at the position where the rolled padding is compressed to a diameter of 550 mm, the squeezing mechanism 5
After stopping, seal the polyethylene bag opening. Then, as shown in FIG. 6, the upper bars 2 and 2'are moved and released in the direction of the arrow, and the narrowing mechanism 5 is lowered. This series of steps can be performed in about 15 seconds and was extremely efficient. The roll-shaped padded cotton in a compressed polyethylene bag was further placed in a polyethylene bag having a diameter of 650 mm, and the compressed state was stored in a slightly opened state. The padding was uniformly compressed in the center direction and had good recoverability. Example 2 After compressing in the same manner as in Example 1 without putting it in a polyethylene bag, compressed padding having a diameter of 700 mm was wrapped with a polyethylene film and sealed with a tape. The padding was uniformly compressed in the center direction and had good recoverability.

[0013]

According to the invention of the present application, since the compression is performed by the narrowing method using the belt, the air-permeable bulky material can be uniformly compressed in the central direction, the product is less damaged, and the required time can be shortened. Further, since the narrowing mechanism can be stopped at an appropriate position, the size or compression ratio of the air-permeable bulky material can be adjusted arbitrarily. In this way, there is an excellent effect that the breathable bulky material can be efficiently distributed and stored.
