Description

  The present invention relates to a sheet processing apparatus for processing a sheet.

  Conventionally, for example, in an offset rotary press, a sheet-like blanket is attached to a blanket cylinder, and a sheet-like printing plate is attached to a plate cylinder. Then, ink is supplied to the printing plate, the ink image on the printing plate is transferred to the blanket, and the ink image transferred to the blanket is transferred to printing paper passing between the impression cylinder and printed.

  A slit is formed on the surface of the blanket cylinder in the axial direction, and both ends of the blanket are inserted into the slit and attached.

  The blanket has a rubber layer formed on the surface of a rectangular metal plate, and both ends of the metal plate longer than the rubber layer are attached by being inserted into slits of the blanket cylinder. Both ends of the metal plate are bent to be inserted into the slits of the blanket cylinder (see, for example, Patent Document 1).

In a bending apparatus that bends both ends of a metal plate of the blanket, the blanket is mounted horizontally on a horizontal table, the bent portions are bent at both ends of the metal plate of the blanket positioned on the table, and the blanket is It is taken out while maintaining its shape. The blanket bending process is the same as in the case of a printing plate (for example, see Patent Document 2).

  By the way, when carrying a blanket, rather than carrying it in a horizontal state, carrying it in a vertical state makes it difficult to deform if it is rolled into a cylindrical shape so that stress is not concentrated in the elastic region of the metal plate of the bracket. It becomes easy.

  However, even if the blanket is carried vertically, it must be mounted from the vertical state to the horizontal state when it is mounted on the horizontal table of the bending apparatus. When taking out from a horizontal table, the blanket must be taken out from the horizontal state to the vertical state, and since such a mass has a large mass ratio of the rubber layer of the blanket, the metal plate of the bracket is easily plastically deformed ( In particular, the portion of the metal plate held by a person is easily plastically deformed), and the processed bent portion is also easily plastically deformed.

  SUMMARY An advantage of some aspects of the invention is that it provides a sheet processing apparatus that can be loaded and unloaded in a posture in which the sheet is hardly deformed and easily carried.

A reference pin 22 is provided for positioning the edge. These reference pins 20, 21, and 22 can be moved up and down between a raised position for positioning the seat 11 and a lowered position for retracting below the seat 11.

  As shown in FIGS. 2 and 7, the bending mechanism 19 on both sides includes an anvil 23 in which an end portion in the longitudinal direction of the sheet 11 is disposed, and an end portion of the sheet 11 while pressing the sheet 11 against the anvil 23. Is provided with a bending unit 24 for bending the wire along the tip of the anvil 23. The anvil 23 is configured to move to the center side of the main body 12 by driving a cylinder or the like so that the tip of the anvil 23 is detached from the bent portion of the sheet 11 after the sheet 11 is bent.

  Further, the table 14 includes a table surface 14a for supporting the sheet 11 in a horizontal state in which the sheet surface 11a faces upward, and an edge portion of the sheet 11 is engageable with one end on the table surface 14a. A stopper 28 is projected. The other end side of the table 28 is supported by the table moving means 15.

  Further, the table moving means 15 is configured so that one end of the table 14 is placed at the storage position (the position shown in FIGS. 5 and 6) where the table surface 14 a is horizontal on the main body 12 and the side of the main body 12. The table 14 is moved between the seat attachment / detachment position (the position shown in FIGS. 1 and 2) where the table surface 14a is lowered and moved sideways. That is, the table 14 is placed on the anvil 23. The processing height at which the sheet 11 is processed by the processing means 13 (the height position shown in FIGS. 5 and 6) and the moving height that allows the sheet 11 to move horizontally above the processing height (shown in FIGS. 3 and 4). Elevating mechanism 31 for moving up and down between the height position and the table 14 of the moving height is stored on the main body 12 and a lateral position on the side area of the main body 12 (position shown in FIGS. 3 and 4). ) And the horizontal movement mechanism 32 that horizontally moves between the A rocking mechanism 33 that rocks between the seat attaching / detaching position is provided. The table 14 at the seat attaching / detaching position is in a state close to a vertical state and in an inclined state in which the table surface 14a stands sideways, and the stopper 28 is positioned on the lower side of the table surface 14a.

  In the elevating mechanism 31, the horizontal movement mechanism 32 is supported by the plurality of guide rod mechanisms 34 so as to be movable up and down with respect to the main body 12, and is moved up and down by a plurality of lifting cylinders 35.

  The horizontal movement mechanism 32 has a pair of rail portions 36 supported by the elevating mechanism 31 so as to be movable up and down, and a moving portion 37 is slidably attached along the rail portions 36. The moving unit 37 can be slid by manual operation.

  The swing mechanism 33 supports the moving portion 37 so that the other end side of the table 14 can swing with the rotary shaft 38 as a fulcrum. Between the position closer to the one end side than the other end of the table 14 and the moving portion 37, a plurality of support mechanisms 39 have functions of supporting the swinging table 14 and fixing it in a horizontal state or releasing the fixing. And a plurality of dampers 40 for reducing the upward swinging load of the table 14 are coupled to each other.

  Next, the operation of the sheet processing apparatus will be described.

  When processing with the sheet 11 mounted on the sheet processing apparatus, as shown in FIGS. 1 and 2, the table 14 is positioned at the sheet attaching / detaching position. The table 14 located at the seat attaching / detaching position is in a state close to a vertical state and in an inclined state in which the table surface 14a is standing sideways, and the stopper 28 is positioned on the lower side of the table surface 14a.

  Since the sheet 11 is not easily deformed and easily carried in the vertical state, the sheet 11 carried in the vertical state is kept in the same position, and the edge located below the sheet 11 is placed on the stopper of the table 14. The sheet surface 11a is placed on the table 14 along the table surface 14a.

  As shown in FIGS. 3 and 4, by swinging the table 14 upward, the table 14 swings from the seat attachment / detachment position to the upper side position around the rotation shaft 38 and becomes horizontal. The table 14 in the horizontal state is fixed by the support mechanism 39. The swing of the table 14 changes the posture of the seat 11 from the vertical state to the horizontal state.

  Further, by pushing the table 14 toward the main body part 12, the moving part 37 moves along with the rail part 36 together with the table 14, and the table 14 is loaded on the main body part 12 from the side position of the main body part 12. Move horizontally to position.

  After the table 14 is moved to the loading position on the main body 12, as shown in FIGS. 5 and 6, the table 14 is lowered from the moving height to the processing height by the lifting cylinder 35, and both end portions of the sheet 11 are moved. To the height of anvil 23.

  Thereafter, the sheet 11 on the table 14 is shifted to a predetermined processing position area, the reference pins 20, 21, 22 are raised, and the two adjacent sides of the sheet 11 are brought into contact with the reference pins 20, 21, 22 to make the sheet 11 is positioned at a predetermined processing position.

  Then, the end of the sheet 11 is bent along the tip of the anvil 23 while the end of the sheet 11 is pressed against the anvil 23 by the bending unit 24 of the bending mechanism 19.

  Further, after the sheet 11 is bent, the anvil 23 is moved toward the center of the main body 12 by driving a cylinder or the like, and the tip of the anvil 23 is removed from the bent portion of the sheet 11.

  The reference pins 20, 21, 22 are lowered, and the sheet 11 is moved to a position where it contacts the stopper 28 of the table 14.

  The lifting / lowering cylinder 35 raises the table 14 from the processing height to the moving height, and the seat 11 is separated from the anvil 23 upward.

  As shown in FIGS. 3 and 4, when the table 14 is pulled out from the main body 12 toward the side, the moving portion 37 moves along the rail portion 36 together with the table 14, and the table 14 moves to the main body. It moves horizontally from the loading position on 12 to the side position on the side of the main body 12.

  Further, as shown in FIGS. 1 and 2, the table 14 is moved around the rotation shaft 38 by releasing the fixation by the support mechanism 39 and swinging the table 14 downward against the damper 40. Swings from one position to the lower seat attachment / detachment position. By swinging the table 14, the posture of the seat 11 is changed from the horizontal state to the vertical state.

  Since the sheet 11 can be taken out from the table 14 at the seat attachment / detachment position in the vertical state, the sheet 11 can be transported in the vertical state.

  As described above, in the sheet processing apparatus, the table moving unit 15 causes the table 14 to stand sideways on the side of the main body 12 and the storage position where the table surface 14a is horizontal on the main body 12. Since the seat 11 can be moved between the seat attachment and detachment positions, the seat 11 can be mounted and taken out in a vertical posture so that the seat 11 is not easily deformed and easy to carry.

  Further, when the seat 11 is mounted, the table 14 supporting the seat 11 at the seat attaching / detaching position is swung to the side position by the swing mechanism 33, and is horizontally moved from the side position to the storage position by the horizontal movement mechanism 32, When the lifted mechanism 31 lowers the moving height from the moving height to the processing height, and when the processed sheet 11 is taken out, the lifting mechanism 31 raises the table 14 from the processing height to the moving height, and the horizontal moving mechanism 32 The sheet 11 can be moved horizontally from the storage position to the side position, and can be swung from the side position to the sheet attaching / detaching position by the swing mechanism 33, so that the seat 11 can be mounted and taken out smoothly.

  Further, by manually swinging and horizontally moving the table 14, the work can be performed while confirming that the sheet 11 is not deformed.

  The swinging and horizontal movement of the table 14 may be automatically performed using a driving source such as a cylinder or a motor.

  In addition, the seat attachment / detachment position of the table 14 is not limited to the inclined state as in the above-described embodiment, but by using a holding or holding means so that the sheet 11 does not come off or fall down from the table 14, It may be closer or vertical. Thus, the closer to the vertical state, the less the change in the posture of the sheet 11, and the plastic deformation of the sheet 11 can be more reliably prevented.

  Further, the sheet 11 can be similarly applied to a blanket, a printing plate, and other sheet-like sheets that require processing.
