Description

  The present invention relates to a sealing strip removing device that pulls out a sealing strip having a predetermined number of paper sheets sealed therein.

  2. Description of the Related Art Conventionally, there is known a processing apparatus that processes a bundle in which a predetermined number of small bundles (sealing belts) of a predetermined number of paper sheets are collected and bundled with a large belt (see, for example, Patent Document 1). .) This processing apparatus cuts and removes the large band from the bundle received via the conveyor, cuts out the bundles of the accumulated state one by one, cuts and removes the small bands from each bundle, and removes the paper sheets of roses. A pre-processing machine is provided to supply to a subsequent processing unit.

  In this pre-processing machine, when cutting the small band of the small bundle, the small band is sandwiched between the two clamp arms by curving the small bundle and cutting the small band between the two sets of clamp arms. The small band is cut off by moving the paper sheets in the small band by moving the arms apart from each other.

However, according to the conventional mechanism described above, separation of the small band failed due to the posture of the small bundle or glue of the small band, and the cut piece when the small band was cut remained between the paper sheets, There were problems such as various problems occurring in the process and a reduction in the operating rate of the apparatus.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, the external appearance of the paper sheet processing apparatus 1 is shown in perspective view. The paper sheet processing apparatus 1 includes a bundle processing machine 2 that receives a bundle of uninspected paper sheets and takes out a bundle of inspected paper sheets. The bundle processing machine 2 is connected to an inspection machine 6 via a conveyor 4. Between the conveyor 4 and the inspection machine 6, a pre-processing machine 10 for releasing the bundle of bundles to be input to the inspection machine 6 is disposed.

  For example, a bundle T (see FIG. 2) in which 10 bundles of bundles t of 100 sheets of paper sheets P sealed with small bands k are collected and bundled together with large bands K (see FIG. 2) is fed through the bundle processor 2. It is thrown into the processing device 1.

  A bundle T of sheets fed through the bundle processor 2 is conveyed to the preprocessor 10 via the conveyor 4. The pre-processing machine 10 cuts and removes the large band K from the bundle T of conveyed paper sheets and removes the small band k from each of the ten loose bundles t to remove it. T is supplied to the inspection machine 6 in a state where T is separated and accumulated on each sheet P.

  The inspection machine 6 takes out and inspects a plurality of paper sheets P that have been separated one by one by the pre-processing machine 10, and as a result of this inspection, 100 sheets of paper sheets that are determined to be reusable. Is re-sealed with a small band k to form a bundle, and 10 bundles are bundled together with a large band K to form a bundle. Then, the sheet bundle bundled by the inspection machine 6 in this way is conveyed in the reverse direction via the conveyor 4 and taken out via the bundle processing machine 2.

  FIG. 2 shows a schematic configuration of the above-described preprocessor 10.

  The pre-processing machine 10 cuts and removes the take-in part A that takes in the bundle T conveyed from the bundle-handling machine 2 via the conveyor 4 and the large band K of the bundle T that is taken in via the take-in part A. A direction changing unit C and a direction changing unit C that change the direction in a state where 10 bundles t (hereinafter referred to as a bundled bundle S) from which the processing unit B and the large band K are cut are sandwiched in the accumulation direction. A cutout portion D cut out one by one from the integrated bundle S that has undergone direction change, a printing portion E that prints on the small band k of the small bundle t cut out by the cutout portion D, and a paste that peels off the paste from the small strip k and is thermally bonded Peeling part F, small band processing part G for extracting and removing the small band k from which glue has been peeled off, and grip t cut out by the cutting part D are printed part E, adhesive peeling part F, and small band processing part G The conveyance part H conveyed to the inspection machine 6 via is provided.

  The bundle T conveyed from the bundle processor 2 via the conveyor 4 is taken into the pre-processor 10 via the take-in part A, and the large band K is cut off by the large band processor B. The bundled small bundle S in a state where the large band K is cut off by the large band processing unit B and the binding is released is changed in direction through the direction changing unit C, and then supplied to the cutting unit D along the stacking direction. Is done.

  The cutout part D is provided with a lift conveyor d extending upward toward the printing part E and the glue peeling part F so that the integrated bundle S supplied from the direction changing part C is pressed against the lift conveyor d with a predetermined pressure. It has become. Then, one bundle is cut out from the bundle t located at the end of the bundled bundle S by the lift conveyor d, and each time the bundled bundle S is moved toward the lift conveyor d by the thickness of 1 bundle t. Thus, the small t is cut out one by one.

  The handle t cut out one by one by the cutting unit D is placed and transported on the transport table h of the transport unit H, printed on the small band k by the printing unit E, and then directed toward the inspection machine 6. Be transported. In the middle, the glue between the small band k and the paper sheet P at the end is peeled off at the glue peeling part F and thermally bonded. Then, the small band k of the small bundle t that has been subjected to the de-glue process is extracted by the small band processing unit G, and a plurality of paper sheets P in a stacked state are supplied to the inspection machine 6.

  FIG. 3 is a block diagram showing the configuration of the small band processing section G that functions as the sealing band sampling apparatus according to the embodiment of the present invention. FIGS. 4 to 9 show an operation explanatory diagram for explaining the operation of the small band processing unit G, and FIG. 10 shows a flowchart for explaining the operation of the small band processing unit G. It is.

First, the structure of the small band processing unit G will be described with reference to FIGS. 3 and 5.
As illustrated in FIG. 3, the small band processing unit G includes a control unit 20 that controls processing operations. The control unit 20 includes a clamp mechanism 21 and a moving mechanism 22 for operating the clamp arm 31, a bending mechanism 23 and a moving mechanism 24 for operating the bending arm 32, and a clamp mechanism 25 for operating the catch arm 33. And a moving mechanism 26 is connected.

  The clamp arm 31 and the clamp mechanism 21 function as a grip restraining mechanism of the present invention, and the bending arm 32, the bending mechanism 23, the catch arm 33, and the clamp mechanism 25 function as a band restraining mechanism of the present invention, and a moving mechanism. 22 and the moving mechanisms 24 and 26 function as a sampling mechanism of the present invention.

  As shown in FIG. 5, the clamp arm 31 includes an upper arm 34 and a lower arm that clamp the grip t cut out on the transfer table h by the lift conveyor d at the left end portion in the drawing where the small band k is not wound. 35. The upper arm 34 located on the upper end side of the bundle t in the stacking direction has a curved surface 34a that protrudes toward the paper sheet P at the upper end in the stacking direction. For this reason, when the clamp mechanism 21 is operated and the handle t is clamped by the clamp arm 31, the handle t is bent in the illustrated posture (convex toward the transfer table h). As a result, a gap s is formed between the upper surface of the curved handle t and the small band k around which the handle t is wound.

  Further, the bending arm 32 operates the bending mechanism 23 to press the both ends in the short direction of the handle t placed on the transport table h at the position where the small band k is wound. As a result, the small band k is restrained by the bending arm 32 and the handle t is further bent. That is, the bend t bent by the clamp arm 31 as described above is further bent by the bending arm 32 in the same bending direction. Thereby, the gap s is further increased. In other words, the clamp arm 31 functions to bend the handle t in a predetermined direction in advance to assist the bending operation by the bending arm 32. The curved arm 32 has a friction member 32a such as a rubber sheet at a portion that abuts against the end side of the handle t.

  Further, the catch arm 33 is inserted into the gap s at a position where the small band k is clamped by operating the moving mechanism 26, and only the small band k is clamped by operating the clamp mechanism 25. In this way, since the catch arm 33 clamps the small band k alone, the curved arm 32 described above does not necessarily need to press and restrain the handle t at the position of the small band k.

Next, the processing operation of the small band processing unit G having the above structure will be described according to the flowchart of FIG. 10 with reference to FIGS.
First, when the handle t is cut out on the transport table h, the clamp arm 31 is moved to a predetermined position by the operation of the moving mechanism 22 and the end of the handle t is clamped by the operation of the clamp mechanism 21, as shown in FIG. (FIG. 10; step 1). In this state, the handle t can be moved along the transfer table h in the direction of arrow a in FIG. That is, the handle t cut out on the transport table h is moved along the transport table h through the printing unit E, the peeling-off unit F, and the small band processing unit G while being clamped by the clamp arm 31.

  When the handle t is conveyed in the direction of the arrow a and moved to the small band extraction position (step 2), the bending arm 32 is moved as shown by the arrow b in the drawing by the operation of the bending mechanism 23 as shown in FIG. Press t from both ends and clamp. As a result, the small band k is restrained and the handle t is sufficiently curved (step 3).

  Thereafter, the movement of the moving mechanism 26 causes the catch arm 33 to move to a position where the small band k is clamped via the gap s as shown by an arrow c in FIG. The small band k is clamped as shown (step 4). In this state, the small band k is constrained by the bending arm 32 and the catch arm 33.

  Further, as shown in FIG. 7, the movement of the moving mechanism 22 moves the clamp arm 31 in a state where the handle t is restrained in the direction of the arrow e in the figure, and the state where the clamp arm 31 is restrained by the curved arm 32 and the catch arm 33. The band k and a plurality of stacked paper sheets P are relatively moved and separated (step 5). At this time, instead of moving the clamp arm 31 as described with reference to FIG. 7, the bending mechanism 32 and the catch arm 33 in a state in which the moving mechanism 24, 26 is operated to restrain the small band k as shown in FIG. 8. You may make it move to the arrow f direction in the figure, and extract the small band k.

  Then, as shown in FIG. 9, the bending arm 32 is released as indicated by an arrow g in the drawing to release the restraint of the small band k by the operation of the bending mechanism 23 (step 6), and the moving mechanism 26 is operated, The catch arm 33 in a state where the small band k is clamped and moved is moved in the direction of the arrow h in the figure, and the small band k is stored in a storage unit (not shown) (step 7).

  As described above, according to the present embodiment, since the small strip k wound by winding a plurality of accumulated paper sheets P is cut out without being cut, the small strip k is removed as in the prior art. Compared with the method of cutting and removing k, the cut piece of the small band k is not generated. That is, according to the present embodiment, problems such as a jam due to a cut piece when the small band k is cut off are not generated, and the operating rate of the apparatus can be increased.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments. For example, you may delete some components from all the components shown by embodiment mentioned above. Furthermore, you may combine the component covering different embodiment suitably.

  For example, in the above-described embodiment, the end of the small band t is pressed by the bending arm 32 at the position where the small band k is wound to restrain the small band k, and at the same time, the small bundle k is bent. Not limited to this, the end of the small bundle t may be pressed and curved at a position where the small band k is not wound. In this case, when pulling out the small band k, the catch arm 33 restraining the small band k and the clamp arm 31 restraining the handle t may be relatively moved so as to pull out the small band k.
