Abstract

PROBLEM TO BE SOLVED: To make it possible to produce a large amt. of new cushioning material small bags for packaging that do not pollute the environment, with a high efficiency, by arranging shredders continuously in two stages and setting the cutting width of second shredding smaller than the cutting width of first shredding. SOLUTION: A supply conveyor 1 supplies paper materials to be fabricated, such as waste paper. The first shredder 2 is formed of a pair of rotary cutters cylindrically arrayed with small-width cutters at revolving shafts. The second shredder 3 comprises a pair of the rotary cutters cylindrically arrayed with the cutters narrower than the cutter width of the first shredder 2 and reshreds the compressed lumpy pieces while loosening these pieces after cutting with the first shredding. A riser conveyor 4 transfers the cut and threaded pieces to a hopper 6. A paper chute 10 is molded to a tubular form along the external shape of a guide chute 11 and is formed by connecting the joint seam 15 in the longitudinal direction in the upper part of a three- way sealer section 12 and fusing an adhesive by a fusing roller 13. The top and bottom of the cut part of a paper tube is thereafter cut simultaneously and the cushioning small bags 17 are continuously produced.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the secondary use of small pieces of OA paper, office paper, etc. to prevent the leakage of corporate secrets, and the reuse of cardboard used as factory waste and used paper such as old magazines as cushioning materials. .

[0002]

2. Description of the Related Art A number of Schletters have been sold as shredders to prevent the above-mentioned leakage of corporate secrets.
Further, Japanese Utility Model Registration No. 3015845 is known as a use of a cushioning material for cardboard which is a waste material of a factory. Further, Japanese Utility Model Laid-Open No. 5-75169 is known as a cushioning material for packaging.

[0003]

In the above-mentioned known examples, individual shredding machines are proposed, and Utility Model Registration No. 3015845 is limited to corrugated cardboard material and is not suitable for mass production. There was a problem.

[0004]

In order to solve the above-mentioned problems, a belt conveyor for supplying a paper material to be processed such as waste paper, a shredding device facing the belt conveyor, and a shredding device from the shredding device. This is an apparatus for forming and manufacturing a paper cushioning material, comprising a start-up conveyor for receiving and transferring, a hopper for receiving small fragments from the start-up conveyor, and a packaging and forming apparatus provided with means for vertically supplying the fixed amount from the hopper. In addition, the shredding device is arranged continuously in two stages,
The present invention is characterized in that the cutting width of the shredding is set to be small, and the apparatus for forming and manufacturing a paper cushioning material as described above.

[0005]

According to the above construction, OA paper, office paper,
Waste paper such as corrugated cardboard and old magazines from factory waste is uniformly shredded and continuously conveyed, and is quantitatively supplied to paper sachets to continuously produce cushion sachets. In addition, since the continuous paper is arranged in two stages when shredding used paper, in the case of shredding old magazines and thick waste paper, compressed pieces can be formed in a lump at the first stage by rough cutting, but cut from the first shred width. In the second-stage chopping with the width set to be small, re-shredding is performed while unraveling, so that uniform cut strips as hulls are formed and the cushioning property is further improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration will be described with reference to the drawings embodying the present invention. FIG. 1 is a side view in which the present invention is implemented, and is an explanatory view in which a part is omitted. FIG. 2 is a plan view.

1 is a flat belt supply conveyor, and 2 is a first conveyor.
The cutter is formed from a pair of rotary blades having a narrow cutter on a rotary shaft and arranged transversely. In this embodiment, the blade width is 11 mm and the rotation diameter is 150 mm. It can be cut to the thickness of the phone book, and small pieces are about 1
It is 0.5 mm long and 40 mm long. Reference numeral 3 denotes a second shredding device, which is constituted by a pair of rotary blades having a narrower cutter width than the first shredding device 2 and arranged in a body, and the blade width in this embodiment is set at 4 mm. The fine pieces have a width of about 3.8 mm and a length of about 50 mm. After being cut by the first shredding, the compressed mass is appropriately shredded and shredded again, and appropriately entangled into a uniform shape to form a fluffy shape.

Reference numeral 4 denotes a rising conveyor, which is provided with lugs laterally provided on a flat belt and transfers the fine pieces cut by the second shredding device to the hopper 6. The hopper 6 has a cylindrical guide chute 11 extending at the lower end and a feed screw 7 standing inside. Reference numeral 8 denotes a driving unit which applies a rotating force by a motor 9;
Reverse rotation program controlled to supply a fixed amount.

Reference numeral 10 denotes a paper sheet, and a guide chute 1
1 is formed into a tube shape along the outer shape of 1, and a joint edge 15 in the vertical direction is adhered at the upper part of the three-way sealer portion 12, and the adhesive applied in advance is welded by the welding roller 13.

Numeral 14 denotes an optical sensor switch which senses the pile height of the small pieces put into the paper tube and instructs the cutter 16 so that the upper and lower cut portions of the paper tube are adhered and cut at the same time as the cushion pouch 17 is cut. Is manufactured continuously. The cushion pouch 17 is dropped onto the carry-out conveyor 18 and transferred to a desired container. Reference numeral 19 denotes an operation panel for performing program control of a main source and a packaging machine. The length of the cushion pouch is variable in three stages.

In FIG. 2, reference numeral 20 denotes a paper roll which is wound around a paper sheet of a cushion pouch 17 and is sent to the guide chute 11 described above. The operation panel 19 described above is used to set the length of the cushion pouch 17, detect the input amount of the small pieces, control the rotation of the motor 9, and operate the cutter 1.
6 is equipped with an instruction control circuit.

[0012]

As described above, a novel packaging that does not pollute the environment by shredding used office waste paper and factory waste paper without discrimination and mixing them together without discrimination. It is possible to efficiently produce a large amount of cushioning material bags. In particular, since the combination of the two-stage shredding device can obtain a constant fluffy buffer material, the profit is high.
