Description

  The present invention relates to a fanfold paper block dividing device for dividing a fanfold paper block in which a plurality of folded fanfold paper blocks are arranged through perforations into blocks.

  In general, for example, in the process of manufacturing a fanfold paper in which a label is temporarily attached to a mount, as shown in FIG. For example, this block B includes a single-direction perforation in which a single block Ba composed of a set of fanfold paper F that is alternately folded and overlapped with the one-direction perforation Ma as a boundary is perpendicular to the one-direction perforation Ma. A plurality of columns are provided with Mb as a boundary.

  And this block B is divided | segmented for every block single-piece | unit Ba, and this is packed and shipped as a product. Conventionally, the operation of dividing the block B of the fanfold paper F into individual blocks Ba is performed by tearing the single block Ba so as to be divided at the perforated line Mb by the operator's manual work. Yes.

  Further, conventionally, in a sheet in which fanfold paper F is continuous, when the perforation portion is cut by hand, the fanfold paper before and after the perforation is cut with a frame-shaped pressing plate in order to facilitate cutting. Also known is a technology that keeps the sheet pressed so that the sheet is stretched without sagging, and that the fanfold paper is separated by reliably cutting from the perforation by simply tracing the perforation with your finger. (For example, published in Japanese Utility Model Laid-Open No. 5-41697).

By the way, in the block B of the fanfold paper F described above, the work of dividing the single block Ba one by one is a manual operation, and even though there are perforations in the single block Ba, a large number are superimposed. When tearing two block single Ba sandwiching the perforated line Mb at the perforation, the block single Ba is pressed well and a large force is applied to the single block Ba so that a shearing force is generated. Therefore, there is a problem that the work is extremely complicated. In addition, the trouble of transporting the divided block Ba becomes complicated.
Further, since the block unit Ba is divided manually, there is a problem that the fanfold paper F is cut at a place other than the perforation and the paper itself is torn if the hand slips.

  In order to solve this, it is also conceivable to create a pressing plate that presses the block B used when cutting the continuous sheet of the conventional fanfold paper, and to divide by hand while holding the block B with this pressing plate. . However, although the work efficiency is improved to some extent, it does not change to dividing by hand, so that a great improvement cannot be achieved.

  The present invention has been made in view of the above-described problems, and it is possible to divide a fanfold paper block with a machine and to automate the division work so that the efficiency of the division work can be improved. It aims at providing the cutting device for blocks.

  In order to solve the above-described problems, the fanfold paper block cutting device according to the present invention is configured such that a single block made of a set of fanfold papers that are alternately folded and overlapped with a one-way perforation as a boundary. In a fanfold paper block dividing device for dividing a plurality of rows of fanfold paper blocks arranged in the other direction perforation perpendicular to the perforation, the block unit at the forefront of the block A pressing mechanism that presses from above and cuts and separates from the rearmost block unit with a perforation in the other direction, and when the pressing mechanism presses the foremost block unit of the block, the foremost block A pressing mechanism for pressing the single block at the rear of the single block, and the pressing mechanism abuts against the upper surface of the single block at the foremost position. A pressing plate that has a surface and is supported so as to be movable up and down, and a pressing plate drive unit that moves the pressing plate up and down to bring the contact surface of the pressing plate into contact with the upper surface of the frontmost block alone The contact surface of the pressing plate is formed obliquely at a predetermined angle with respect to the direction of the other direction perforation.

  As a result, when dividing the fanfold paper block, the frontmost block unit of the block is supported on the table so as to protrude from the front edge of the table, and the frontmost block unit is pressed from above by the pressing mechanism. The pressing force and the reaction force of the table cause a shearing force in the other direction perforations, and the other direction perforations are cut to divide the foremost block unit. At this time, since the rear block unit is pressed by the pressing mechanism rather than the foremost block unit, the perforation in the other direction is reliably performed by the pressing mechanism. For this reason, since the block unit is divided by the pressing mechanism, the dividing operation can be automated, and the efficiency of the dividing operation can be improved. In addition, since the pressing mechanism divides the block unit while pressing the block unit by the pressing mechanism, it is possible to prevent the situation where the fanfold paper is cut or torn apart from the perforation as compared with the case of the conventional manual work. .

  According to the present invention, since the pressing mechanism divides the single block while holding the single block by the pressing mechanism, the dividing work can be automated, and the dividing work efficiency can be improved. In addition, it is possible to prevent a situation in which the fanfold paper is cut or torn at a place other than the perforation as compared with the case of the conventional manual work. In addition, the fanfold paper manufacturing process, folding superimposing process, dividing process, and packaging process can be automated by incorporating them into a series of lines, so that fanfold paper production efficiency can be greatly improved. become.

Then, for example, a position of the push plate 21 that contacts the rear surface of the block B is detected by a sensor (not shown), and the servo motor 26 is controlled by a control unit (not shown) based on the detection result, so that the push plate 21 advances. Sometimes, the foremost block unit Ba of the block B is sequentially transferred to the predetermined position X.
Alternatively, a value for the width of the one-direction perforation Ma of the block B and a value for the width of the single block Ba are input in advance to a control unit (not shown), and stopped at a predetermined position X based on the input width value. The moving distance in the transfer direction R is calculated. Then, the servo motor 26 is controlled based on the calculation result, and the foremost block unit Ba of the block B is sequentially transferred to the predetermined position X when the push-in plate 21 advances.

Further, the present apparatus includes a pressing mechanism 30 that divides the foremost block single unit Ba in the block B from the block single unit Ba that is one rearward of the block single unit Ba. This pressing mechanism 30 presses the foremost block single unit Ba of the block B transferred and positioned at a predetermined position X from above, and this forefront block single unit Ba is formed in the other direction perforation along the front end edge 5a of the table 1. Cutting with Mb.

And a pressing plate driving unit 40 that makes the contact surface 32 contact the upper surface of the foremost block unit Ba.

The contact surface 32 of the pressing plate 31 is inclined at a predetermined angle with respect to the direction of the other direction perforation Mb of the block B. The inclination angle θ is set to θ = 5 ° (FIG. 2), for example.
A movable base member 33 that can move up and down is provided below the plate support 5. The movable base member 33 is supported by a pair of guide rails 34 erected on the base 2 at the left and right ends of the movable base member 33 through a slide bearing 35 so as to be slidable.

The left and right end portions are respectively supported by the pair of stay dampers 36. In addition, a pair of support posts 37 are provided on the left and right of the movable base member 33 in the transfer direction R, and the pressing plate 31 is inserted through the pair of support posts 37 at the left and right ends of the transfer direction R. A stopper 38 for preventing the pressing plate 31 from coming off from the support 37 is provided at the upper end of the support 37.

  As shown in FIG. 2, the pressing plate driving unit 40 moves the movable base member 33 up and down to move the pressing plate 31 up and down, and is provided on the base 2 and driven by a servo motor 41 to be driven by a driving pulley 42. A driven pulley 44 rotatably provided on the base 2 via a bracket 43, a driving pulley 42, a belt 45 spanning the driven pulley 44, and a lower surface of the movable base member 33 and the driven pulley 44. And a crank mechanism 46 that converts the rotation of the driven pulley 44 into a linear motion of the movable base member 33.

In addition, as shown in FIGS. 1, 3, and 4A, the present apparatus is transported and positioned at the predetermined position X when the pressing mechanism 30 presses the foremost block unit Ba of the block B. In addition, a holding mechanism 50 is provided to hold the block single unit Ba which is one rearward of the block single unit Ba which is the frontmost block of the block B. The pressing mechanism 50 includes a pressing plate 51 that is supported so as to be movable up and down and presses the block unit Ba that is one rearward from the frontmost block unit Ba by its own weight when the unit moves downward. The holding plate 51 is slidably guided by the guide rails 34 at the left and right ends in the transfer direction R, and is supported so as to move up and down.
The pressing plate 51 of the pressing mechanism 50 is supported by protrusions 55 that protrude from the end members 54 provided on the left and right of the pressing plate 31 of the pressing mechanism 30 toward the pressing plate 51, and are pressed by the pressing mechanism 30. The pressing plate 51 is moved when the plate 31 is moved upward, and the pressing plate 51 is moved downward by its own weight when the pressing plate 31 is moved downward. A weight 52 is attached to the upper side of the holding plate 51. Since the presser plate 51 presses the rear block unit Ba with its own weight, a driving unit for forcibly pressing is not required, and the apparatus can be simplified accordingly. Moreover, since the pressing plate 51 can be moved up and down using the pressing mechanism 30, the apparatus is not wasted and the apparatus can be simplified. In the embodiment, the protrusion 55 is provided with a hole through which the guide rail 34 is inserted, and is supported so that the guide rail 34 can move up and down. Thereby, the guide rail 34 can move up and down stably.

  Further, in the present apparatus, the front end edge 5a of the plate support portion 5 of the table 1 is provided continuously at the front end thereof and supports the foremost block unit Ba protruding from the front end edge 5a. A support plate 60 that moves up and down following the pressing plate 31 is provided. Four rods 61 are suspended from the four corners of the support plate 60, respectively. A fixed base member 62 fixed to the base 2 is provided below the plate support portion 5, and the four rods 61 pass through the fixed base member 62 so that the support plate 60 is attached to the fixed base member 62. It is supported so that it can move up and down. In addition, coil springs 63 respectively inserted into the rods 61 are provided between the fixed base member 62 and the support plate 60. The coil spring 63 causes the bearing plate 60 to be positioned flush with the plate support portion 5 by its urging force, and is applied by this pressing force when the pressing plate 31 of the pressing mechanism 30 moves downward by pressing the block unit Ba. The force is reduced against the force, and the support plate 60 is moved downward while supporting the block unit Ba.

  Furthermore, as shown in FIGS. 1, 2, and 4, the discharge transport for receiving and discharging the block single unit Ba after being cut by the push plate 21 of the transfer positioning mechanism 20 is received at the front of the support plate 60. A mechanism 70 is provided. The discharge conveyance mechanism 70 is configured by a belt conveyor 71 that conveys the block B in the transfer direction R. When only the last block unit Ba of the block B remains on the table 1, the push-in plate driving unit 22 of the transfer positioning mechanism 20 discharges the last block unit Ba at a predetermined timing. The push-in plate 21 is moved forward to a position where it is transferred to the belt conveyor 71. The control of the push-in plate driving unit 22 of the transfer positioning mechanism 20 is performed by, for example, a control unit (not shown) based on the detection of the position of the push-in plate 21 and the values of the width of the one-direction perforation Ma of the block B and the width of the block unit Ba. To do.

Therefore, when the block B of the fanfold paper F is divided by the fanfold paper block dividing apparatus according to this embodiment, the following is performed.
As shown in FIGS. 1 and 2, the block B is supplied and conveyed by the belt conveyor 11 of the supply and conveyance mechanism 10, and the block B is transferred and transferred to the roller support part 4 of the table 1 by the roller conveyor 12. The block B hits the stopper 13 and is supported by the roller support 4 of the table 1 so that the one-direction perforation Ma is along the transfer direction R.

  In this state, the servo motor 26 of the transfer positioning mechanism 20 rotates the ball screw 25 to advance the push-in plate 21 through the support arm 23 so as to contact the rear surface of the rearmost block unit Ba in the block B on the table 1. Then, the rear surface is pushed in the transfer direction R, and the foremost block unit Ba of the block B is transferred and positioned at a predetermined position X as shown in FIGS. At the predetermined position X, the other-direction perforation Mb between the foremost block single Ba and the block single unit Ba one next to the frontmost block single Ba is the transfer direction of the plate support 5 of the table 1. The foremost block unit Ba is located along the front end edge 5a orthogonal to R, and is supported by the support plate 60 so as to protrude from the front end edge 5a of the plate support portion 5 of the table 1. In this case, since the block B is transferred by pushing the push-in plate 21, it is easy to move, and the block unit Ba can be reliably transferred and positioned at the predetermined position X by adjusting the push-in amount.

In this state, as shown in FIGS. 2, 3, and 4 (a) and 4 (b), the pressing plate drive unit 40 operates, and the movable base member 33 is moved downward via the crank mechanism 46 to press the pressing plate 31. Move down. By the downward movement of the pressing plate 31, the pressing plate 51 of the pressing mechanism 50 carried by the projection 55 of the end member 54 of the pressing plate 31 is also moved downward by its own weight, and the pressing plate 51 is moved to the foremost block. The single block Ba, which is one rear of the single Ba, comes into contact with the upper surface and is pressed.
When the pressing plate 31 further moves downward, as shown in FIGS. 3B and 4C, the pressing plate 31 presses the foremost block unit Ba from above, and this pressing force and the table 1 Due to the reaction force, a shearing force acts on the other direction perforation Mb, the other direction perforation Mb is cut, and the foremost block single unit Ba is divided. At this time, since the presser plate 51 of the presser mechanism 50 presses the block unit Ba which is one rearward of the block unit Ba at the frontmost position of the block B, the perforation Mb in the other direction is cut by the presser plate 31. Surely done. Further, in this case, the pressing plate 31 contacts and presses against the upper surface of the block unit Ba, so that it can be surely divided by the perforation without being displaced from the paper surface.

  Furthermore, since the contact surface 32 of the pressing plate 31 is inclined at a predetermined angle θ with respect to the direction of the other direction perforation Mb, the contact surface 32 of the block unit Ba is moved with the downward movement of the pressing plate 31. Since a pressing force is applied to the upper surface in order from one side edge to the other side edge, a shearing force is gradually applied to the perforation. The stitches Mb are cut, and the other-direction perforations Mb are surely cut to divide the block unit Ba. Furthermore, since the pressing plate 31 is supported by the pair of dampers 36, the impact at the time of contact with the single block Ba is absorbed. For this reason, compared with the case of the conventional manual work, the situation where the fanfold paper F is cut or torn at places other than the perforations is also prevented.

  In this case, as shown in FIGS. 3B and 4C, the block unit Ba that is pressed and divided by the pressing mechanism 30 is supported by the support plate 60. When the plate 31 presses the block single unit Ba and moves downward, the pressing plate also moves the support plate 60 following the press plate 31 while supporting the block single unit Ba against the urging force of the coil spring 63. Therefore, since the block single Ba to be divided is supported by the support plate 60, it is possible to prevent the block single Ba from falling. In addition, since the support plate 60 moves down following the pressing plate 31, the block unit Ba can be supported until the cutting at the other direction perforation Mb is completed, so that the other direction perforation Mb portion can be surely cut. Can do.

  When the block unit Ba is divided, as shown in FIGS. 2 and 3, the pressing plate driving unit 40 is operated, and the movable base member 33 is moved upward via the crank mechanism 46 to move the pressing plate 31 upward. Return to the original position. Further, due to the upward movement of the pressing plate 31, the protrusion 55 of the end member 54 of the pressing plate 31 carries the pressing plate 51 of the pressing mechanism 50, so that the pressing plate 51 is also moved upward and returned to its original position. It is done. Further, when the pressing plate 31 of the pressing mechanism 30 moves upward, there is no pressing force on the divided block unit Ba, so that the support plate 60 follows the pressing plate 31 while supporting the block unit Ba by the urging force of the coil spring 63. Move up.

  Then, again, similarly to the above, the transfer positioning mechanism 20 advances the push-in plate 21 to transfer and position the foremost block unit Ba of the block B to the predetermined position X. In this case, as shown in FIG. 2A, the block single unit Ba that is divided and supported by the support plate 60 is also pushed out in the transfer direction R, so that it is moved forward from the support plate 60. Then, the divided block Ba is received by the discharge conveyance mechanism 70 and discharged and conveyed. Therefore, the block single unit Ba after the division is reliably transported, and subsequent packaging and the like are facilitated.

  Thereafter, in the same manner as described above, the single blocks Ba are sequentially divided and discharged and transported by the discharge transport mechanism 70. When only the last block unit Ba remains on the table 1 in one block B, the pushing plate drive unit 22 of the transfer positioning mechanism 20 receives the last block unit Ba in the discharge conveyance mechanism 70. The push-in plate 21 is moved forward to the passing position. For this reason, the last remaining block Ba remaining at the end can be reliably discharged and conveyed.

  When the division of one block B is completed in this way, the block B is supplied and conveyed again by the belt conveyor of the supply and conveyance mechanism 10, and the division operation is performed in the same manner as described above. Thus, according to the fanfold paper block dividing apparatus according to the embodiment, the pressing mechanism 30 divides the block unit Ba while pressing the block unit Ba by the pressing mechanism 50, so that the dividing operation can be automated. Thus, it is possible to improve the division work efficiency. In addition, it is possible to prevent the fanfold paper F from being cut or torn apart from the perforation as compared with the case of the conventional manual work. In addition, the fanfold paper F manufacturing process, folding superimposing process, dividing process, and packaging process can be automated by incorporating them into a series of lines, and the production efficiency of the fanfold paper F can be greatly improved. become able to.
