Description

  The present invention relates to a rubber roller recycling apparatus used in, for example, a printing press.

  For example, the printing press includes a paper feeding device, a printing device, and a paper discharge device. The paper supply device supplies a print medium, the print device performs printing on the print medium, and the paper discharge device discharges the printed print media in a superimposed manner. A printing apparatus of such a printing machine supplies ink by rotating a number of ink rollers, each roller of a dampening device, a plate cylinder, a blanket cylinder, and the like, and performs printing on a printing medium. A part of these many ink rollers and each roller of the dampening device are constituted by rubber rollers in which rubber is wound around the peripheral surface.

  This rubber roller uses synthetic rubber, for example, nitrile rubber (NBR), as the rubber to be wound. It reacts with ink when used for a certain period of time, and the plasticizer in the rubber solid is extracted, so that the rubber hardness is initially set. It rises above the hardness and the diameter of the roller is reduced. Then, it becomes difficult to supply an appropriate amount of ink, and it becomes difficult to form a uniform ink film thickness, resulting in a decrease in print quality. In this case, the rubber on the peripheral surface is replaced with a rubber roller that has been used for a certain period. However, the rewinding work of rubber in the rubber roller generates enormous parts costs and work costs.

  As what solves such a problem, there exist some which were described in the following patent documents 1-3, for example. The ink form roller described in Patent Document 1 forms a urethane rubber single layer on a roller core, and the rubber hardness of the urethane rubber single layer is 40 ° to 45 ° when the surface temperature of the single layer is 25 ° C. It is set. In the method for regenerating and repairing a rubber roll described in Patent Document 2, after the surface of the rubber roll is polished with a minimum cutting allowance, an unvulcanized new rubber is wound and vulcanized by a mold press. In the offset printing method described in Patent Document 3, the silicone rubber blanket removed from the printing roll is immersed in a liquid having miscibility with butyl carbitol, which is a solvent in the printing ink stored in the liquid storage container, for a predetermined time. Thus, butyl carbitol contained in the blanket is extracted into a liquid.

  However, it is difficult to form the rubber hardness of the urethane rubber single layer on the roller metal core to a specific hardness with respect to the temperature, as in the ink form roller of Patent Document 1 described above, and the manufacturing cost increases. End up. Further, when the new rubber is vulcanized and molded after the surface of the rubber roll is polished as in the method of regenerating and repairing a rubber roll in Patent Document 2, the manufacturing cost increases. Further, when the silicone rubber blanket removed from the printing roll is immersed in the liquid as in the offset printing method of Patent Document 3, the liquid acts on the back surface and the end surface that are not used on the blanket. The thickness may be non-uniform.

  Hereinafter, the operation of the rubber roller regeneration device of the present embodiment will be described in detail.

  As shown in FIGS. 1 and 2, first, the rubber roller 100 to be recycled is supported on the first support device 11. With the support position adjusting device 17, the positioning pin 40 is extracted from the positioning hole 35 and the through hole 39, and the positioning bracket 38 is brought into a free state with respect to the positioning plate 34. Here, the support shaft 100a of the rubber roller 100 is supported by the support portion 26 by the bearing portion 28, the support shaft 100b is supported by the support portion 29 by the bearing portion 31, and is prevented from being detached by the fixtures 32 and 33, respectively. Then, the positioning pin 40 is fitted from the through hole 39 to the positioning hole 35, and the positioning bracket 38 is fixed to the positioning plate 34. In this case, the rubber roller 100 is positioned at a position where the entire length of the rubber roller 100 falls within the entire length of the pressing roller 12.

  When the rubber roller 100 is supported by the first support device 11, as shown in FIGS. 5 and 6, the roller moving device 14 then moves the pressing roller 12 toward the rubber roller 100, and the surface of the pressing roller 12. Thus, the surface of the rubber roller 100 is pressed. When the air cylinders 49 and 53 are driven to extend the drive rods 51 and 55, the support portions 43 and 46 rotate clockwise in FIG. 6 with the mounting shafts 50 and 54 as fulcrums, and the pressing roller 12 Moves toward the rubber roller 100, and a pressing force C is applied to the surface of the rubber roller 100 by the pressing roller 12.

Thus, the rubber roller 100 and the pressing roller 12 are reciprocally moved in the axial direction. When the air cylinder 36 is driven to reciprocate, the support portion 26 reciprocates with respect to the positioning bracket 38 fixed to the positioning plate 34, whereby the rubber roller 100 reciprocates in the axial direction and reciprocates relative to the pressing roller 12. .

  At the same time, when the solvent supply source 16 is driven to supply the solvent S containing plasticizer to the surface of the rubber roller 100 by the solvent supply device 16, the solvent S is supplied to each solvent supply unit 64 through the solvent supply hose 65. The solvent S is dropped from the center of the rubber roller 100 onto the surface on the pressing roller 12 side from each solvent supply unit 64.

  Then, as shown in FIGS. 5 and 6, since the rubber roller 100 rotates in the direction of arrow A and the pressing roller 12 rotates in the direction of arrow B, the solvent S is placed at the contact position between the rubber roller 100 and the pressing roller 12. The solvent S spreads in the axial direction of the rubber roller 100, so that the solvent S is applied to all surfaces in the axial direction of the rubber roller 100. Moreover, the solvent S is applied to all surfaces in the circumferential direction of the rubber roller 100 by rotating the rubber roller 100 and the pressing roller 12 in contact with each other. The rubber roller 100 and the pressing roller 12 may be synchronously rotated or may be different speed (slip) rotation. In addition, since the rubber roller 100 reciprocates, the solvent S accumulated at the contact position between the rubber roller 100 and the pressing roller 12 is likely to spread in the axial direction of the rubber roller 100 and the pressing roller 12, and all of the rubber roller 100 in the axial direction. The solvent S is applied to the surface of the film.

  At this time, the rubber roller 100 is not only applied with the solvent S but also given a pressing force C, so that the plasticizer easily enters the rubber roller 100. That is, since the rubber roller 100 is applied with the pressing force C only at the contact position of the pressing roller 12, the pressing force C is intermittently applied to the surface of the rubber roller 100. Therefore, the rubber roller 100 contracts due to the pressing force C by the pressing roller 12, and in particular, when the pressing force C is released, the plasticizer contained in the solvent S enters the inside from the surface and expands. Then, the rubber roller 100 returns to a state close to the initial state as the hardness of the rubber decreases and the outer diameter increases.

  Thereafter, as shown in FIG. 6, the removal plate moving device 72 brings the removal plate 71 into contact with the surface of the rubber roller 100 in a state where the pressing force C is applied to the rubber roller 100 rotated and oscillated by the pressing roller 12. Then, the glaze deposited and deposited on the surface of the rubber roller 100 is removed by the removal plate 71. When the air cylinders 78 and 79 are driven and the drive rods 80 and 81 are extended, the container 82 and the removal plate 71 rise together with the lift plate 75, and the removal surface 71a of the removal plate 71 contacts the surface of the rotating rubber roller 100. To do. Since the rubber roller 100 is applied with the pressing force C with the solvent S attached to the surface, the glaze attached to the surface is easily peeled off. Here, when the removal surface 71 a of the removal plate 71 is brought into contact with the surface of the rubber roller 100, the glaze raised on the surface of the rubber roller 100 is removed by the removal plate 71.

  By performing this rubber roller regeneration process for a predetermined time, the rubber roller 100 is returned to a state close to the initial state as the hardness of the rubber decreases, the outer diameter increases, and the glaze on the surface is removed.

  Here, the operation timing of the rubber roller regeneration device of the present embodiment will be described. FIG. 8 is a time chart showing the operation of the rubber roller regeneration device of the present embodiment. The cycle operation time is one cycle operation time in a certain mode setting of the rubber roller regeneration device.

  As shown in FIG. 8, by driving each air cylinder 49, 53 of the roller moving device 14 at time t1, the pressing roller 12 is moved to the rubber roller 100 side, and the pressing roller 12 causes the rubber roller 100 to move. A pressing force C is applied to the surface. By driving the drive motor 57 of the roller rotating device 15 at time t2, the pressing roller 12 rotates, and the rubber roller 100 in contact with the rotating roller 15 rotates.

  At time t3, the air cylinder 36 of the first oscillating device 18 is reciprocated to reciprocate the rubber roller 100 in the axial direction, and reciprocally move relative to the pressing roller 12. At the same time, the solvent supply device 16 supplies the solvent S containing the plasticizer to the surface of the rubber roller 100. At this time, the solvent supply device 16 drops the solvent S intermittently on the surface of the rubber roller 100. Then, the solvent S spreads in the axial direction of the rubber roller 100 and is applied to all surfaces in the circumferential direction of the rubber roller 100. By driving the air cylinders 78 and 79 of the removal plate moving device 72 at time t4, the removal plate 71 is raised and the removal surface 71a is brought into contact with the surface of the rotating rubber roller 100.

  In the solvent supply device 16, two solvent supply portions 64 are opposed to the end portion in the axial direction of the rubber roller 100, and two solvent supply portions 64 correspond to the central portion, for a total of four solvent supply portions 64 in the axial direction of the rubber roller 100. They are evenly spaced. In addition, the number of the solvent supply parts 64 in the solvent supply apparatus 16 is not limited to four, and can be set suitably. At time t3, all the solvent supply units 64 intermittently drop the solvent S onto the rubber roller 100 at the same timing. At time t <b> 5, the amount of the solvent dropped in the two solvent supply units 64 arranged corresponding to the respective end portions of the rubber roller 100 is decreased.

  After that, at time t6, the air cylinders 78 and 79 of the removal plate moving device 72 are driven, so that the removal plate 71 is lowered and the removal surface 71a is separated from the surface of the rotating rubber roller 100. At time t7, the amount of solvent dripping in the two solvent supply units 64 arranged corresponding to the central part of the rubber roller 100 is decreased, and two pieces arranged corresponding to each end of the rubber roller 100 are reduced. The amount is the same as the amount of solvent dropped in the solvent supply unit 64.

  Thereafter, the supply of the solvent S to the rubber roller 100 by the solvent supply device 16 is stopped at time t8. At time t9, the driving rotation and swinging operation of the rubber roller 100 are stopped, and at time t910, the pressing roller. 2 is separated from the rubber roller 100.

  In this case, the time t1 to the time t5 is the solvent application / penetration step, the time t5 to the time t6 is the glaze removal step, and the time t6 to the time t10 is the solvent infiltration step. In the solvent application / penetration step, a pressing force is applied while applying the solvent S while the rubber roller 100 is rotated and rocked, and the solvent S is uniformly applied to the rubber roller 100 to promote penetration. In the glaze removal process, the glaze peeled off from the surface of the rubber roller 100 is removed by the removal plate 71. In the solvent permeation step, the solvent S is uniformly applied to the surface of the rubber roller 100 from which the glaze has been removed.

  FIG. 9 is a graph showing the reproduction result of the rubber roller of this embodiment. The graph of FIG. 9 represents a change in rubber hardness after the rubber roller is regenerated. This rubber roller 100 has an initial rubber hardness of 30 in an unused rubber roller, and has increased to a rubber hardness of 35 when used over a certain period. In FIG. 9, the one indicated by the alternate long and short dash line represents the rubber hardness of the rubber roller processed by the rubber roller regeneration method in which no pressing force is applied to the rubber roller, and the solid line represents the pressing force against the rubber roller. The rubber hardness of the rubber roller processed by the rubber roller regeneration method of this embodiment to which Here, the rubber roller regeneration method without applying a pressing force is a method in which a pressing force is not applied only by dropping the solvent S containing a plasticizer over a predetermined time onto the rubber roller 100. However, the type of solvent S, the processing time, and the like are the same as in the rubber roller regeneration method of the present embodiment. Further, the rubber hardness of the rubber roller is an average of the measured values at four different locations in the axial direction. The rubber hardness is a standard defined in Japanese Industrial Standard JIS K 6253.

  As can be seen from the graph of FIG. 9, the rubber roller processed by the rubber roller regeneration method that does not apply the pressing force represented by the alternate long and short dash line to the rubber roller having a rubber hardness of 35 before the regeneration is near the rubber hardness of 30 immediately after the regeneration. However, the rubber hardness increased with the lapse of time, and increased to near the rubber hardness 33 when 15 days passed. On the other hand, the rubber roller processed by the rubber roller regeneration method of the present embodiment that applies a pressing force represented by a solid line to the rubber roller having a rubber hardness of 35 before the regeneration decreases to a rubber hardness of about 29 immediately after the regeneration. The rubber hardness increased with the lapse of time, but when about 15 days passed, the rubber hardness was maintained at an increase to a rubber hardness of 30.3, which was close to the initial rubber hardness of 30. Thus, it can be seen that the rubber roller regeneration method of the present embodiment that applies a pressing force has a sufficiently high effect of reducing the hardness of the rubber as compared to the rubber roller regeneration method that does not apply the pressing force.

  As described above, in the rubber roller regeneration device according to the present embodiment, the first support device 11 that rotatably supports the rubber roller 100 and the press disposed adjacent to the rubber roller 100 supported by the first support device 11.

The rubber roller 100 is rotated and rotated, and the solvent S is supplied to the surface of the rubber roller 100 by the solvent supply device 16. Then, the rubber roller 100 rotates in a state where a pressing force is applied to the surface by the pressing roller 12, and the solvent S is applied to the surface. Therefore, when the rubber of the rubber roller 100 is contracted by this pressing, the plasticizer contained in the solvent S enters the inside from the surface and expands. Then, the rubber hardness of the rubber roller 100 decreases and the outer diameter increases to return to a state close to the initial state. As a result, it is not necessary to perform an expensive regeneration process on the rubber roller 100, an increase in the regeneration cost can be suppressed, and the rubber can be reproduced with the hardness reduced appropriately.

  That is, the rubber roller 100 used for a certain period of time is hardened and shrinks in diameter, and glaze adheres to the surface and accumulates. Simply applying the solvent S containing the plasticizer to the surface of the rubber roller 100 temporarily reduces the hardness of the rubber, but immediately returns to the original hardness. Therefore, as in the present embodiment, when the pressing force C is applied in a state where the solvent S containing the plasticizer is applied to the surface of the rubber roller 100, the solution S easily enters the inside due to the sponge effect when the rubber roller 100 contracts, It becomes easy for the plasticizer to stay inside. Therefore, the rubber of the rubber roller 100 can be effectively reduced and reproduced.

  Further, the rubber roller 100 is repeatedly applied with a pressing force to the surface by the pressing roller 12, so that the surface of the rubber roller 100 is repeatedly contracted and restored by the pressing, and an appropriate amount of plasticizer contained in the solvent S is obtained. Can get inside. Further, since the pressing roller 12 and the rubber roller 100 are brought into close contact with each other and a pressing force is applied to the surface of the rubber roller 100, a uniform pressing force can be applied to the axial direction of the rubber roller 100. The hardness can be reduced uniformly over the entire region.

Accordingly, by adjusting the contact angle between the rubber roller 100 and the pressing roller 12 by the contact angle adjusting device 19, even if the pressing roller 12 is bent, the surfaces of the rubber roller 100 and the pressing roller 12 are brought into contact with each other without any gap. Therefore, a uniform pressing force can be applied to the rubber roller 100 in the axial direction.
