A rising conveyor that transports upward, a hopper that receives fine fragments from the rising conveyor, and a hopper with a cylindrical guide chute extending at the lower end, and a feed screw standing up and feeding means for quantitative feeding up and down A paper cushioning material molding and manufacturing apparatus comprising a packaging molding apparatus provided in a direction, wherein the shredding device is formed from a pair of rotary blades having a narrow cutter arranged on a rotary shaft and continuously two stages. Provided is a paper cushioning material molding and manufacturing apparatus characterized in that the cutter width of the downstream second shredding device is set narrower than that of the upstream first shredding device . Further, the packaging molding apparatus includes a guide chute that forms a paper sheet in a tube shape below the hopper, a sealer portion that adheres a seam of the paper sheet, and a stack height of the fine pieces put into the molded paper tube. A sensor switch that senses the height, and a cutter part that operates according to the sensor switch information to bond the upper and lower cut parts of the paper tube and cuts them into cushion sachets in the vertical direction. There is provided a molding and manufacturing apparatus for a paper cushioning material, characterized in that it has a control section.
[0005]
[Action]
With the configuration described above, OA paper, office paper, factory waste corrugated cardboard and old paper such as old magazines are uniformly shredded and continuously conveyed, and quantitatively supplied to paper sachets to produce cushion sachets continuously.
In addition, because it is arranged continuously in two stages for chopping waste paper, in the case of severing old magazines and heavy waste paper, the first stage can make a compacted piece by rough cutting, but cut from the first shredding width In the second stage shredding with the width set small, the shredding is performed while unraveling, so that a uniform cut strip as a wing is formed and the cushioning property is further enhanced.
[0006]
【Example】
The configuration will be described based on the drawings in which the present invention is implemented.
FIG. 1 is a side view in which the present invention is implemented, and is an explanatory diagram with a part omitted. FIG. 2 is a plan view.
[0007]
Reference numeral 1 denotes a flat belt supply conveyor, and reference numeral 2 denotes a first shredding device, which is formed of a pair of rotary blades having a narrow cutter arranged on a rotating 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 about the thickness of the phone book, and the fine pieces are about 10.5 mm wide and 40 mm long.
Reference numeral 3 denotes a second shredding device, which is composed of a pair of rotating blades having a cutter arrayed narrower than the cutter width of the first shredding device 2. The blade width in this embodiment is set to 4 mm. The fine piece has a width of about 3.8 mm and a length of about 50 mm. After being cut by the first shredding, the compressed lump pieces are appropriately shredded and appropriately tangled into a uniform shape to form a fluffy shape.
[0008]
Reference numeral 4 denotes a rising conveyor, which is appropriately provided with a lug horizontally 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 upright. Reference numeral 8 denotes a drive unit which applies a rotational force by a motor 9, and the operation is appropriately controlled by forward, stop, and reverse rotation program control.
[0009]
Reference numeral 10 denotes a paper sheet, which is formed into a tube shape along the outer shape of the guide chute 11, has a vertical joint edge 15 bonded to the upper part of the three-way sealer portion 12, and is preliminarily applied by the welding roller 13. The adhesive that is present is heat welded.
[0010]
14 is an optical sensor switch that senses the height of the fine pieces deposited in the paper tube and instructs the cutter 16 to bond the top and bottom of the cut portion of the paper tube and simultaneously cut the cushion pouch 17 continuously. To manufacture. The cushion pouch 17 falls onto the carry-out conveyor 18 and is transferred to a desired container. 19 is an operation panel for controlling the main source and the packaging machine section. The length of the cushion pouch is variable in three stages.
[0011]
In FIG. 2, reference numeral 20 denotes a paper roll, which is a roll of a paper sheet of a cushion sachet 17 and is sent to the guide chute 11 described above.
The operation panel 19 includes a length setting of the cushion pouch 17, sensing of the amount of fine pieces inserted, rotation control of the motor 9, and an instruction control circuit for the cutter 16.
[0012]
【The invention's effect】
Because it is configured as described above, a new packaging material sachet that does not pollute the environment by shredding the used waste paper material of the office or the paper of the factory waste material without mixing. It can be efficiently produced in large quantities.
In particular, the combination of the two-stage shredding device can provide a constant fluffy cushioning material, which is highly beneficial.
