Description

  The present invention relates to an improvement of a shredder that cuts an object to be processed such as an unnecessary document by a cutter, and particularly relates to appropriately cutting the object to be processed by preventing a paper jam.

  In a shredder that uses a cutter to finely cut an object to be processed such as a document that is no longer needed, in general, the paper is sent to the cutter at the input port for each arbitrary number of documents to be processed. It was done by throwing in.

  In this case, the operator confirms the completion of cutting of the input documents when cutting a large number of documents, and again classifies the remaining documents to be cut into a predetermined number of sheets, and inputs the next document to be processed. There is a problem that it is necessary to repeatedly perform the work to be performed, and it takes a lot of time and effort for the processing work, and the worker is restrained by the work for a long time.

  For this reason, the operator rushed the process, and there was a tendency to input a document having a thickness more than an appropriate number, and the input port of a general shredder had an opening width enough to accept it. There was a tendency that a large amount of input became more prominent.

  However, if a large number of documents are input into the input port at this time, a paper jam occurs, and more work and time are taken away from the paper jam removal operation, such as reverse rotation of the cutter, removal of the jammed paper, and re-input. On the other hand, there was a problem that extra labor and time were required for the cutting process.

  In this case, an automatic feed roller is installed so as to face the wide slot, and a paper drop opening is formed between the automatic feed roller and the lower surface of the slot, and this paper drop slot (automatic feed roller and slot) It has been proposed to cope with this by setting the gap between the two in accordance with the cutting ability of the cutter (for example, Patent Document 1).

  However, even if the distance between the automatic feeding roller and the insertion port is adjusted in this way, if the number of documents that can contact the automatic feeding roller is not limited, for example, the end face of the document to be discarded is a little. When the paper is fed out of phase, the next paper to be sent out is caught in the automatic feed roller, and the paper may be jammed between the input port and the automatic feed roller. In other words, paper that exceeds the processing capacity of the automatic feed roller is sent to the automatic feed roller, and a phenomenon similar to a paper jam between rotating cutters that occurs in a general shredder occurs between the input port and the automatic feed roller. In the end, this causes paper jams, and the removal work has the same time and effort as before. In addition, when an automatic feed roller is installed, there is a problem in that the structure is complicated and labor and cost are required for manufacturing.

Furthermore, the rotation stop of the cutter due to a paper jam may be caused not only by the processing at the document input stage but also by the cut waste. That is, if waste is stored more than necessary in the waste receptacle (trash bin) that stores the cut waste, this processed waste is caught in the cutter and sent out between the rotating cutters. There is a risk that paper rotation may be hindered and cause paper jams, and the conventional technology has no meaning in preventing paper jams due to such causes.

  As a fourth means for solving the above-described problems, the present invention includes a cutter unit and a receiving unit that receives the waste cut by the cutter unit, and the cutter unit includes an input port and an input port for an object to be processed. In a shredder having a cutter that cuts a workpiece that has been thrown in from, a feeding port is in contact with an end surface of the workpiece that exceeds a predetermined thickness to limit delivery of the workpiece that exceeds a predetermined thickness, The present invention provides a shredder characterized in that an object to be processed having a thickness equal to or less than a thickness of 10 mm is sent to a cutter.

  The present invention provides, as a fifth means for solving the above-described problems, in the fourth solution means, wherein the input port is disposed obliquely, and the object to be processed from the receiving surface of the input port to a predetermined thickness is processed. The present invention provides a shredder characterized by being sent to a cutter for each object.

  As a sixth means for solving the above-mentioned problems, the present invention includes a cutter unit and a receiving unit that receives waste cut by the cutter unit. In a shredder that has a cutter that cuts the workpiece input from the input port, the cutter is placed at a position where the rotating circle drawn by the cutter is closest to the wall of the shredder and discarded to the side closest to the wall of the receiving part. A shredder characterized by dropping an object is provided. The “position where the rotating circle drawn by the cutter is closest to the wall of the shredder” refers to the rotation space of the cutter, the member for joining the wall to the other wall, the support mechanism of the cutter, It means the position where the cutter can be installed so that the rotation circle drawn by the cutter in design is closest to the wall surface after arranging the parts necessary for design, safety considerations, etc.

  According to the present invention, as a seventh means for solving the above-mentioned problems, in the sixth solving means, the nearest wall surface of the cutter is a wall surface on the waste removal side of the shredder. Is to provide.

The present invention provides a shredder characterized by being sent out to a cutter installed on the front part of the shredder for each object.

  According to the present invention, as a tenth means for solving the above-mentioned problem, in any one of the above fourth to ninth solving means, the interval between the walls constituting the inlet is 1.5 mm or less. It provides a shredder that is characterized.

  According to the present invention, as eleventh means for solving the above-described problem, in any one of the fourth to tenth solving means, the receiving part includes waste that has fallen to the nearest side to the wall surface of the receiving part. The present invention provides a shredder characterized in that a confirmation means for confirming the state of accumulation from the outside is formed.

  According to the present invention, as described above, the interval between the walls constituting the charging port is adjusted, and the wall surface around the charging port forming the charging port is brought into contact with the end surface of the workpiece exceeding a predetermined thickness. By restricting the delivery of the processed object exceeding the predetermined thickness, the processed object having the predetermined thickness or less is sent to the cutter, so that the processed object is not sent out more than necessary. There is an actual benefit that paper jam due to excessive supply can be reliably and easily prevented with a simple structure. Note that the predetermined thickness can be set as a thickness at which supply of the workpiece to the cutter does not become excessive, that is, a thickness of the workpiece that can be processed by the cutter at a time.

  In particular, according to the present invention, since the inlet is disposed obliquely and is sent to the cutter for each workpiece from the receiving surface of the inlet to a predetermined thickness, the workpiece exceeding the predetermined thickness Is in contact with the inlet and waits for the next feeding, and after the workpiece that has entered the inlet first is sent out, the workpiece to the next predetermined thickness sequentially enters the inlet, so a large amount of Even if the document is installed at the insertion port, the workpiece is appropriately sent out, so that there is an advantage that the processing is not required and the worker is not unnecessarily restrained.

  In this case, according to the present invention, as described above, the gap between the walls of the inlet is greatly reduced to 1.5 mm or less compared to 5 mm to 7 mm of a general shredder. Therefore, there is an advantage that paper jam can be surely prevented.

  Further, according to the present invention, as described above, the cutter is installed at the nearest position to the wall surface such as the front surface of the shredder, and the waste is dropped to the nearest side to the wall surface of the receiving portion. Compared to the case where the waste is dropped near the center of the receiving part, the waste is not stored on average, but is stored higher along the wall from the side closer to the wall. Wastes due to excessive savings can be given to the processor by giving a psychological approach to the receiving capacity of the receiving part as if it was approaching the acceptance limit as soon as possible, and disposing of the waste at an early stage. This prevents the paper from being caught in the cutter and reliably suppress the paper jam, and at the same time has the advantage that the waste does not overflow from the receiving portion.

  In this case, in particular, according to the present invention, the nearest wall surface of the cutter is provided on the nearest wall portion of the shredder waste removal side wall so that it can be relatively easily checked from the outside. Since waste is stored highly from the near side, there is a benefit that it is possible to more easily check the state of waste storage and reliably prevent paper jams due to early disposal of waste. .

  Furthermore, according to the present invention, as described above, since the receiving part is formed with a confirmation means such as a small window that can confirm the accumulation state of the waste that has dropped to the nearest side to the wall surface of the receiving part, Since the state of saving of waste after cutting can be confirmed with more certainty, there is an actual advantage that prevention of paper jams due to early disposal of waste can be achieved more reliably.

  The embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 to 3 show a shredder 10 according to the present invention. The shredder 10 includes a cutter portion 12 and a shredder 12 as shown in FIGS. And a receiving portion 14 that is disposed below the cutter portion 12 and receives the waste cut by the cutter portion 12.

  As shown in FIGS. 2 to 5, the cutter unit 12 includes a workpiece inlet 16 and a cutter 18 for cutting the workpiece input from the inlet 16. As shown in FIGS. 1 to 4, the cutter 18 includes a plurality of cutter bodies 18 </ b> A and 18 </ b> B arranged in opposition to each other in the illustrated embodiment. In particular, as shown in FIG. 3, the insertion port 16 can be formed by opening a part of the cabinet of the cutter unit 12.

  As shown in FIG. 5, each cutter body 18A, 18B is formed by attaching a large number of blades 18b to the outer periphery of a roller 18a rotated by a motor 20, and a plurality of the other cutter bodies 18A, 18B. The blades 18b are installed in a staggered manner without interference. Accordingly, a workpiece such as a document to be cut finely is cut into pieces by the rotating blade 18b by being fed between the two cutter bodies 18A and 18B.

  In the illustrated embodiment, the receiving portion 14 includes a receiving portion main body 14A and a receiving box 14B accommodated in the receiving portion main body 14A, as shown in FIGS. In the embodiment shown in FIGS. 1 to 3, the receiving portion main body 14 </ b> A includes a back plate portion 14 a and left and right side plate portions 14 b, and the receiving box 14 </ b> B is on a rail 22 formed below the receiving portion main body 14. Is stored in the receiving portion main body 14 so as to be freely inserted into and removed from the front surface of the shredder 10, and the waste material cut by the cutter portion 12 is stored.

  Accordingly, in the illustrated embodiment, in particular, as shown in FIG. 1, the front plate of the receiving box 14B becomes the front part 14c of the receiving part 14 as it is, and the receiving box 14B is moved forward from the receiving part main body 14A. By pulling out, the stored waste can be discarded. That is, in the illustrated embodiment, the front portion 14c of the shredder 10 serves as a waste outlet. It should be noted that the receiving box 14A is not limited to a form that is pulled out to the front (front side) as in the illustrated embodiment, and is attached to the receiving portion main body 14A so as to be swingable by a pivot at the lower side. It can also be set so that the waste committee can be taken out at an angle.

  As shown in FIGS. 1 and 2, the front plate of the receiving box 14B serving as the front part 14c of the receiving part 14 has a confirmation means 24 that can confirm the state of waste accumulation in the receiving box 14B from the outside. Is formed. Specifically, a transparent small window 24A formed on a part of the front plate of the receiving box 14B can be used as the confirmation means 24. Therefore, the waste processor can visually confirm the waste accumulated increasingly high from the outside through the small window 24A. For this reason, when the small window 24A is accumulated up to a height suitable for taking out the waste from the receiving portion 14, it is desirable to arrange the accumulated arrangement at a height that can be seen from the outside. As a result, it is possible to easily recognize that the amount of waste stored has reached an amount suitable for disposal.

  In the present invention, the cutter 18 is installed at a position where the rotation circle A (see FIGS. 4 and 5) drawn by the cutter 18 is closest to the wall surface of the shredder 10. More specifically, the blade 18b of the cutter body closer to the wall surface side of the shredder 10 (the cutter body 18A in the illustrated embodiment) of the two cutter bodies 18A and 18B arranged opposite to each other is designed. The cutter 18 is installed so as to be disposed as close to the wall surface of the shredder 10 as possible. That is, in particular, as shown in FIGS. 4 and 5, the size and shape of the support member 26 of the cutter 18 can be ensured with sufficient strength as well as the rotational space of the cutter body 18A. After setting the parts necessary for ensuring the original functions of the cutter 18 such as the design for vibration isolation and safety considerations, the cutter body 18A is installed closest to the wall surface by design. The cutter body 18A is disposed at a position where it can be performed.

  In this case, particularly as shown in FIGS. 4 and 5, the tangent line X (see FIGS. 4 and 5) between the cutter body 18A closest to the wall surface and the other cutter body 18B faces the nearest wall surface. Further, by disposing the other cutter body 18B on the wall surface at a position obliquely below the nearest cutter body 18A, waste can be dropped to the nearest side to the wall surface of the receiving portion 14.

  Therefore, as shown in FIG. 3, the waste is not stored on average compared to the case where it is dropped near the center of the receiving portion 14, as shown in FIG. Along the wall surface, it is stored highly from the side close to the wall surface. For this reason, it is possible to give the waste processor a psychological action as if it is approaching the acceptance limit as soon as possible with respect to the acceptance ability of the receiving unit 14, so that the waste can be disposed of at an early stage. Therefore, it is possible to prevent the waste from being caught in the cutter 18 due to excessive storage and to reliably suppress the paper jam, and at the same time, the waste does not overflow from the receiving portion 14.

  In this case, as the nearest wall surface of the cutter 18, it is desirable to set the wall surface on the waste removal side of the shredder 10, that is, the front surface portion 14c of the receiving portion 14 in the illustrated embodiment. Thus, if waste is stored highly from the front portion 14c side of the receiving portion, which is the wall surface on the waste take-out side, the take-out side is relatively easy to check from the outside, so the checking means 24 In combination with the visual effect of the small window 24A, the state of waste storage can be more easily confirmed, and the prevention of paper jams due to the early disposal of waste can be reliably achieved. That is, in the illustrated embodiment, the waste after cutting is dropped toward the front side of the shredder 10.

  Further, in the present invention, as shown in FIG. 4 in particular, the insertion port 16 is in contact with the end surface of the workpiece 1 exceeding the predetermined thickness and restricts the delivery of the workpiece 1 exceeding the predetermined thickness, The workpiece 1 having a predetermined thickness or less is sent out to the cutter 18. In this case, the predetermined thickness can be set to a thickness at which supply of the workpiece 1 to the cutter 18 does not become excessive, that is, a thickness of the workpiece 1 that can be processed by the cutter 18 at a time.

  For this reason, even if an attempt is made to insert the workpiece 1 having a thickness exceeding the predetermined thickness toward the input port 16, the document that is the workpiece 1 exceeding the predetermined thickness is shown in FIG. As shown, the contact with the wall surface around the input port 16 forming the input port 16 is restricted so that the input to the input port 16 is restricted and is not sent to the cutter 18, and the object that has been sent to the tip below a predetermined thickness is shown. After the workpiece 1 is appropriately cut, the workpiece 1 having a predetermined thickness is then sent out from the input port 16 to the cutter 18. Thereby, it is possible to reliably and easily prevent a paper jam due to excessive supply of the workpiece 1 with a simple structure.

  Specifically, the gap S (see FIG. 4) between the walls of the inlet 16 can be dealt with by making it not more than 1.5 mm, which is significantly narrower than 5 mm to 7 mm of a general shredder. it can. In this case, since it is sufficient for the input port 16 to be able to limit the delivery of the workpiece 1, for example, the passage 17 of the workpiece 1 continuous to the input port 16 is formed to have a width of about 3 to 5 mm. At the same time, a stopper (not shown) that contacts the end surface of the workpiece 1 is attached to the opening of the passage 17, and an input port 16 having a distance of 1.5 mm or less is formed between the stopper and one wall surface of the passage 17. You can also

  In particular, in the illustrated embodiment in which the cutter 18 is installed on the front side of the shredder, in accordance with the installation position of the cutter 18, as shown in FIG. It is desirable to arrange it diagonally. Specifically, the insertion port 16 can be formed by inclining in a direction substantially parallel to the tangent line between the two cutter bodies 18A and 18B. In this case, the workpieces 1 are fed out from the receiving surface 16a of the insertion port 16 to the cutter 18 for each workpiece 1 up to a predetermined thickness. For this reason, even if it installs the to-be-processed object 1 which is a large amount of documents in the insertion port 16, since the to-be-processed object 1 is sent out appropriately, a process is not required and an operator can be restrained unnecessarily. Absent.

  The present invention is particularly applicable to a cutting process of an object to be processed that can be cut finely such as a document.
