Waste paper such as used books and old magazines is sorted into high-quality paper, colored paper, rough paper, etc., and then sent to a paper mill for recycling. However, metal objects such as glue and staples that stick to the bindings of used books are It must be removed in advance. Conventionally, these foreign substances were removed manually.

However, manual removal work is very tedious and does not improve work efficiency, and it is difficult to completely remove foreign substances by hand. There was a considerable amount of adhering waste paper and metal objects such as staples mixed in, and these foreign substances made it difficult to recycle the waste paper, and there were problems such as pollution caused by the glue in particular. In addition, sorting the various papers bound into used books into high-quality paper, colored paper, rough paper, etc., as described above, is an extremely time-consuming task.
There was a problem that a large number of workers were required.

In order to solve this problem, a used book cutting device has been proposed, as shown in Japanese Utility Model Application Publication No. 60-45694, which uses a rotary blade driven by a motor to cut the binding portions of used books. According to this cutting device, binding parts of used books etc. that have foreign substances such as glue and staples attached can be cut and removed with light work and efficiency, and the sorting work that follows the cutting work can be easily performed. be.

[Problem that the invention attempts to solve]

However, even with the above-mentioned used book cutting device, there is a problem in that the used books, etc. to be cut must be individually transported to the cutting section of the cutting device by hand, and the preparation work before the cutting operation is time-consuming.

The present invention aims to solve the problems of conventional paper cutting devices and to provide a waste paper cutting device that can efficiently carry out preparation work before cutting.

[Means for solving problems]

In order to achieve the above object, the waste paper cutting device of the present invention is provided with a cutting section consisting of a rotary blade and a fixed blade facing the rotary blade on the upper surface of the platform having a horizontal upper surface extending in the left-right direction. In addition, a receiving box is provided adjacent to the back side of the cutting section, and further, a box-shaped dumper for storing waste paper having an upper opening on the back side of the base part and a partial opening on the receiving box side. The table is pivotally mounted and a push-up means for pushing up the dump table is provided, and by tilting the dump table by the push-up means, the waste paper in the dump table is carried into the receiving box through the partial opening. It is characterized by

[Effect]

When waste paper is put into the dump table from above and the dump table is pushed up using a pushing means such as a hydraulic pump,
The dump platform tilts around the receiving box side. Therefore, the waste paper in the dump table slides down due to gravity, is carried into the receiving box, and is temporarily stored therein. At this time, for example, a shutter is provided on the receiving box side of the dumping platform, and the opening size is limited, so that a large amount of waste paper in the dumping platform is carried into the receiving box at once. There isn't. Since the receiving box and the cutting section are installed adjacent to each other, the operator takes out the waste paper carried into the receiving box, moves it left and right along the horizontal top surface of the table, and transfers the waste paper to the cutting section. By pressing it between the rotary blade and the fixed blade, the bound portion of waste paper can be quickly and easily removed. When you run out of waste paper in the receiving box, make the slope of the dump platform slightly steeper.
The waste paper in the dump table is newly carried into the receiving box.

In this way, the waste paper in the dump table is delivered little by little into the receiving box installed adjacent to the cutting section, making it possible to remove the bound portion of waste paper in a continuous operation, greatly increasing processing efficiency. improve.

is installed.

Reference numeral 24 denotes a carry-in guide plate, and 25 denotes a carry-out guide plate, which are erected on the stand 3 of the cutting section 4. As shown in FIG. 4, the guide surface 24a of the carry-in guide plate 24 is located slightly inside the side surface 5a of the rotary blade 5, but the guide surface 25a of the carry-out guide plate 25 is located slightly inside the side surface 5a of the rotary blade 5. It is almost on the same plane. In other words, the guide surface 2 of the unloading guide plate 25
5a protrudes slightly from the guide surface 24a of the carry-in guide plate 24, and the width T of the protrusion is slightly larger than the width of the binding portion 30a (shaded portion in FIG. 4) of the used book 30, for example, about 5 mm. Ru. Also cutting section 4
Made of transparent synthetic resin etc. so as to cover the entire body.
An L-angled protective cover 6 is provided. This protective cover 6 is provided to prevent the rotary blade 5 from being exposed and injure the operator's hands and fingers, and to prevent cut paper waste from scattering upward. The longitudinal end of the horizontal part 6a of the protective cover 6 is connected to the vertical part 3a of the base part 3 by a hinge means 2.

can be opened and closed in the vertical direction. Further, on the end surface of the vertical portion 6b of the protective cover 6 on the used book insertion side, there is provided an inclined portion 6c whose width becomes gradually wider in accordance with the traveling direction of the used book 30, which is indicated by a thick arrow. Note that 31 is used book 3
A metal object such as a stapler is shown fixed to the binding portion 30a of 0.

Further, a hydraulic pump 42 is connected to a rotating shaft 23b of the motor 23 on the opposite side to the rotating shaft 23a on which the rotary blade 5 is fixed, via an electromagnetic clutch 40 and a transmission 41. A hydraulic hose 43 is arranged between the cylinder 11 and the cylinder 11 .

Next, the operation of the cutting device according to the present invention will be explained.

It is assumed that the dump table 7 is initially in a horizontal state and the motor 23 is also in a stopped state.

First, used books and the like are carried into the dump table 7. Next, after operating the motor switch 19 to rotate the motor 23, the electromagnetic clutch 40 is turned on by the clutch switch 21, the rotation of the motor 23 is transmitted to the transmission 41, and after decelerating the rotation of the motor 23, the hydraulic pump 42 is turned on. , the hydraulic pump 42 is activated, and high pressure oil is sent to the hydraulic cylinder 11 via the hydraulic hose 43. Therefore, the piston rod 11a of the hydraulic cylinder 11 is located at the base 10 of the triangular projection 10.
Press a. At this time, the connection rod 1 is connected between the tip 10b of the triangular projection 10 and the upper end 1a of the frame 1.
2, the distance between the tip 10b and the upper end 1a is constant, and the tip 10b
Since the base portion 10a of the triangular protrusion 10, to which the pressing force from the piston rod 11a is applied, is located above the dump table 7, a force is applied to the dump table 7 to rotate it to the left in FIG. Since the dump table 7 is pivotally supported on the frame 1 by a hinge 8, the dump table 7 tilts around the hinge 8, and some of the used books and the like in the dump table 7 move into the receiving box 13. At this point, the electromagnetic clutch 40 is activated by the clutch switch 21.
is turned off, and the tilting of the dump platform 7 is stopped. At this time, since the shutter 9 is present approximately in the upper half of the front face of the dump table 7, a large amount of used books, etc. in the dump table 7 will not be moved into the receiving box 13.

In this state, the worker places the used book 30 on the stand 3 by holding the side edge opposite to the binding part 30a of the used book 30 that has been moved into the receiving box 13, and places the used book 30 on the stand 3. The side edge on the binding part 30a side is connected to the loading guide plate 2.
4 and slide it along the guide surface 24a toward the cutting section 4. At this time, when the protective cover 6 is in a normal state, the lower end of the vertical portion 6b contacts the surface of the base portion 3 due to its own weight, and the rotary blade 5 is completely covered, so it is safe. Further, when the used book 30 is moved along the top surface of the stand 3 in the direction shown by the thick arrow, the used book 30 comes into contact with the slope 6c of the protective cover 6, so the protective cover 6 is pushed up by the used book 30. With the hinge means 26 as the center of rotation,
When it opens upward and continues sliding in this state, the binding portion 30a is cut across the width T by the rotary blade 5 and the fixed blade 22, and the cut and removed paper waste is sucked by the suction action of the suction blower 15. It is sucked into the suction pipe 16 through the mouth (not shown) and discharged into the discharge pipe 17.
The waste is discharged to the waste box 18 through the filter.

When the used book 30 is further moved to the carry-out guide plate 25 side, the binding portion 30a of the used book 30 is completely cut and removed. At this time, the line a of the used book 30 to be cut is guided by coming into contact with the guide surface 25a of the unloading guide plate 25, which protrudes from the loading guide plate 24 by the width T, so that the old book 30 can be slid on the stand 3. When cutting, the used book 30 does not wobble, and the binding portion 30a side of the used book 30 is cut linearly with a predetermined width T. If the used book 30 is placed on the stand 3 and the guide plates 24 and 25 guide the side edges of the binding portion 30a while sliding and cutting, the binding portion 30a can be cut with extremely light work. can be removed efficiently.

As described above, after cutting the binding part 30a side and removing the metal objects 31 such as glue and staples that would hinder the recycling of waste paper, the waste paper that made up the used book 30 can be converted into high-quality paper, colored paper, etc. Sort into rough paper, etc. This sorting work is performed while holding the used books 30, and is performed consecutively to the above-mentioned cutting work, so that the work can be performed extremely efficiently. That is, in the above-mentioned cutting operation, the user holds the opposite side edge of the binding section 30a of the used book 30 in his hand and slides it on the base section 3 to cut the binding section 30a, but once the cutting operation is completed, The waste paper constituting the used book 30 can be quickly sorted into high-quality paper, colored paper, rough paper, etc. by turning over the waste paper constituting the used book 30 with the other hand while holding the side edge part with one hand. Repeat this operation thereafter.

When the number of used books etc. in the receiving box 13 becomes low, the electromagnetic clutch 40 is turned on again and the dumping platform 7 is turned on again.
The inclination of the electromagnetic clutch 4 is made slightly steeper to move some of the used books etc. in the dump platform 7 into the receiving box 13, and then the electromagnetic clutch 4
0 is off. In this way, during the cutting operation, the dump table 7 is gradually inclined as the cutting operation progresses.

Furthermore, when the remaining amount of used books etc. in the dump table 7 is running low, the slope of the dump table 7 must be made steeper, but at this time the shutter 9 attached to the front part of the dump table 7 may fall over the worker's head. There is a risk that it may get close to the parts and interfere with the work. However, since the shutter 9 is detachably attached to the dump table 7, by removing the shutter 9 from the dump table 7, it does not interfere with the work.

In the above embodiment, two cutting parts 4, 4 are provided.
The reason why the two cutting sections are arranged symmetrically is to enable two workers to perform the cutting work efficiently at the same time using this device.There may be only one cutting section, or three or more cutting sections may be provided. You can also do this.

In addition, in the embodiment of the present invention, the hydraulic pump 4
Since the rotational force of 2 is obtained from the rotating shaft of the motor 23 for rotating the rotary blade, the energy consumption can be reduced and the size can be made smaller compared to the case where a motor exclusively used for the hydraulic pump 42 is used.
Further, since the protective cover 6 covering the rotary blade 5 is provided, the safety of the worker can be ensured with a simple structure and without interfering with the cutting operation.

[Effect of idea]

As described above, according to the present invention, a dump table is provided at the rear of the cutting machine with the rotation center being on the side of the cutting machine, used books etc. to be cut are placed in advance on this dump table, and the dump table is placed on the dump table in advance. By gradually tilting the table, used books, etc. in the dump table can be moved one by one in the direction of the cutting machine, making it possible to do the cutting work efficiently without having to spend much time preparing before cutting. There is an effect.
