Then, in order to detect when the shredded paper debris 47 that has slipped off is loaded in the tube and stored in the upper part of the tube bracket 13, the shredded paper debris sensor 48, which is a transmission type sensor, is placed on the upper part of the tube bracket 13. Through holes 34 are provided on both side walls of the upper part of the tube bracket 13 which are installed facing the side walls and face the shredded paper chip sensor 48, and through which the light of the sensor can pass. In this embodiment, since the direction of the shredded paper debris sensor 48 is set in the longitudinal direction of the tube bracket 13, the length of the transmission area of the sensor is reduced, and the volume of the loaded shredded paper debris 47 is increased. Even if the density is low, the apparent bulk density is increased and the sensitivity is further improved as compared with the case where the shredded paper debris sensor 48 is installed in the front-back direction of the tube bracket 13.

Next, the operation procedure of the present apparatus will be sequentially described.
First, a description will be given of a case where the tube 15 is lost in the shredded paper piece bagging apparatus 1 and is cut out. In this case, it is assumed that the power switch 11 of the shredded paper piece bagging apparatus 1 is turned on, that is, the power is turned on. The front cover 6 of the shredded paper piece bagging device 1 is opened toward the user. In this state, the power is turned off by a door switch (not shown), and the power is turned off, and the inside of the apparatus becomes safe. Then, the tube bracket 13 is detached from the stay 12 and taken out of the outer box 2. By removing the tube bracket 13 from the stay 13, the tube sensor 18 is turned off. The hook 39 on the inner support 37 of the removed tube bracket 13 is engaged with an engagement hole provided on the side wall of the rectangular cylinder of the tube bracket 13, and the inner support 37 is moved toward the side wall of the rectangular cylinder of the tube bracket 13. The width of the tube bracket 13 in the longitudinal direction is reduced. In this state, the spare heat-fusible tube 15 is folded back to the tube bracket 13 and contracted to a predetermined length, and the tube magazine loaded as the annular superimposed body 30 is fitted. Next, the hook 39 is removed from the side wall of the rectangular cylinder of the tube bracket 13 and turned off. By turning off the hook 39, the inner support 37 becomes a hinge function plastic 38.
, And is stretched sideways to hold the annular superimposed body 30 in a state where it can be accurately pulled out. Next, the annular superposed body 3
The outermost tube 15 of 0 is pulled down by about 20 cm. After the above preparation, the tube bracket 13 on which the tube 15 is mounted is hung on the stay 12 again. By mounting the tube bracket 13 on the stay 12, the tube sensor 18 is turned on. Then, the front cover 6 of the shredded paper piece bagging apparatus 1 is closed. When the front cover 6 is closed, the power is turned on by the door switch.

Next, when the start button 35 is pressed and turned on, the origin of use of the shredded paper bagging apparatus 1 is set. That is, the drive motor 42 operates to lift the weight 17 from the position B to the uppermost end A, and push the heat-cut pull-up bar 26 upward at the upper end of the weight 17. Due to the upward movement of the heat-cut pull-up bar 26, the lug plate is pulled up by the link bar 25, and the toggle 22 bent downward in the shape of a trapezoid is pulled up and stretched straight, and a force for pushing to the center acts. Then, the heat cut lever 21 is moved toward the center of the tube 15.
With this movement, the heat cutter 16 provided at the lower end of the heat cut lever 21 also moves toward the center. As a result, the left and right heat cutters 16 and 16 are closed to clamp the tube 15 between them (see FIG. 4). The sandwiched tube 15 is thermally melted by a heat cutter 16 which also serves as a heat sealer.
Cut off the end of. At the same time, the terminal on the main body side of the tube 15 is heat-sealed in a bag shape. Next, the weight 17 immediately descends and stands by at the position B (see FIG. 2). In the above state, according to the first aspect of the present invention, the preparation for putting the shredded paper debris 47 shredded by another shredder into the inlet 9 is completed, and when the shredder of the second aspect of the present invention is installed,
The preparation for the operation of the shredder unit 50 in the interior is completed.

Therefore, in the case of the first aspect of the present invention, shredded paper chip waste 47 is introduced into the inlet 9. In the case of the second aspect of the present invention, paper that requires confidentiality is inserted into the shredder section 50 from the input port 9 and is shredded by the cutter 53 to cut shredded paper chips 47.
And The shredded paper debris 47 flows from the slide plate 55 to the upper portion of the tube bracket 13 and falls into the bag of the tube 15 whose tip is sealed to form a bag (see FIG. 2).
When the shredded paper debris 47 that has fallen into the bag is accumulated and loaded and reaches a position near the slide plate 55, the shredded paper debris sensor 48 detects the loading, stops the operation of the shredder unit 50, and stops the weight of the weight. The drive motor 42 operates to move the weight 17 downward from the stop standby position B while compressing the shredded paper debris 47 in the tube, and the position C in the bag-shaped tube below the position of the heat cutter 16. And simultaneously push the bottom of the sealed bag of the tube further down (see FIG. 3). By pushing down the bottom of the bag, the tube containing the shredded paper chips 47 is pulled downward from the loaded tube bracket and unraveled. The length of the tube 15 loaded to be superimposed on the tube bracket 13 is about 2
You can make 50 packs. Further, if the tube 15 is lost after being unwound as described above, the tube sensor 18 detects that the tube 15 is lost.
Give an alarm. When the shredded paper chip 47 is stored in the tube 15 and pushed down by the weight 17, and the tube 16 having the length of one pack containing the shredded paper chip 47 is obtained at the lower portion of the heat cutter 16, the bag 15 of the tube 15 is formed. Is detected by the bottom length sensor 19 for setting the tube length, and the drive motor 42 of the weight 17 is rotated in the reverse direction. Then, the weight 17 is raised to the position A and pushes up the heat-cut pull-up bar 26. By raising the heat-cut pull-up bar 26, the link bar 25 pulls up the toggle 22 against the spring 24 to make it straight, and at the same time, the power is turned on to the heater 28 and the tube 15 is firmly sandwiched between the two heat cutters 16, 16. And heat-seal the cut end simultaneously (see FIG. 4).

When a predetermined time elapses by a timer (not shown) that is fed into the shredded paper piece bagging apparatus 1, the heater power is turned off, and after the cooling time elapses, the weight 1 is turned off.
7 returns to the standby position of B, the heat cut lever 21 of the heat cutter 16 is opened,
The pack obtained by cutting and sealing the lower part and mounting the shredded paper debris 47 therein is dropped downward to the chute plate 8.
From the device. The resulting pack can be used as it is as a cushioning material to be filled between products for packing, but by opening a pinhole with a needle as appropriate, the air slowly escapes and is ideal with a damper function It becomes a cushioning material. As the material of the heat-fusible tube used in the present invention, polyethylene whose toxic gas emission is reduced as much as possible by combustion is used.

In order to prevent the user from forgetting to turn off the switch of the shredder unit 50, the switch of the shredder unit 50 is temporarily turned off by a built-in timer after a predetermined time has elapsed. To continue using, press the start button 35 again.
