Raw material roll mounting system, raw material roll mounting method, and method for manufacturing sheet processed products

Abstract

To provide a raw material roll mounting system, a raw material roll mounting method, and a method for manufacturing sheet processed products that enable the mounting of raw material rolls to a roll holding shaft without complicating the control system, and that allow for miniaturization and standardization of the raw material roll mounting hand. [Solution] The raw material roll mounting system according to the present invention comprises a raw material roll mounting hand 30, a work robot, and a cylindrical member 40. The raw material roll mounting hand 30 has a rod-shaped member 32 that can be inserted into the core tube RP of the raw material roll RA, a pusher device 35, and a drive device 37. The work robot moves the raw material roll RA with the rod-shaped member 32 inserted, causing the roll holding shaft 11A to be inserted into the core tube RP. The cylindrical member 40 has a flange portion 42 that can contact the pressing member 36 of the pusher device 35 when the rod-shaped member 32 is inserted. The inner diameter of the second open end 41b of the cylindrical body portion 41 is larger than the inner diameter of the core tube RP of the raw material roll RA.

Claims

1. A raw material roll mounting system for attaching a raw material roll to a roll holding shaft that rotatably supports the raw material roll, A raw material roll holding means comprising: a rod-shaped member that can be inserted into the core tube of the raw material roll; a pressing member that presses the raw material roll, in which the rod-shaped member is inserted into the core tube, in a detachment direction to detach it from the rod-shaped member; and a drive device that moves the pressing member in the detachment direction. A moving means connected to the aforementioned raw material roll holding means moves the raw material roll in which the rod-shaped member is inserted into the core tube, and inserts the roll holding shaft into the core tube, The cylindrical body portion has a first open end into which the rod-shaped member can be inserted and a second open end opposite to the first open end, and the cylindrical member has a projection that protrudes from the outer surface of the cylindrical body portion and can contact the pressing member when the rod-shaped member is inserted into the first open end. A raw material roll mounting system wherein the inner diameter of the second open end is larger than the inner diameter of the core tube of the raw material roll.

2. The pressing member is, The aforementioned rod-shaped member has a hole through which it can freely pass, The raw material roll mounting system according to claim 1, wherein the cylindrical member is attached to the rod-shaped member, and the system has a contact surface that contacts the protruding portion.

3. The raw material roll mounting system according to claim 2, wherein the pressing member is a plate-shaped member having a donut shape.

4. The pressing member is movable back and forth along the longitudinal direction of the rod-shaped member between a first position and a second position located further in the direction of departure than the first position. The raw material roll mounting system according to any one of claims 1 to 3, wherein the second position is set at a position spaced apart from the tip of the rod-shaped member in the direction opposite to the direction of separation when viewed from a direction intersecting the longitudinal direction.

5. The raw material roll mounting system according to any one of claims 1 to 4, wherein the tip of the rod-shaped member has a shape that tapers towards the tip.

6. The inner diameter of the second open end is less than or equal to the outer diameter of the core tube. The raw material roll mounting system according to any one of claims 1 to 5, wherein the outer diameter of the second open end is greater than or equal to the outer diameter of the core tube.

7. A method for mounting a raw material roll using the raw material roll mounting system described in any one of claims 1 to 6, The core tube insertion step involves moving the raw material roll, in which the rod-shaped member is inserted into the core tube, using the aforementioned moving means, and inserting the roll holding shaft into the core tube. After the core tube insertion step, the raw material roll pressing step is performed by moving the pressing member in the detachment direction using the drive device, thereby pressing the raw material roll. A method for mounting a raw material roll, comprising: after performing the raw material roll pressing step, moving the rod-shaped member into which the cylindrical member is inserted by the moving means toward the roll holding shaft while positioning it on the same axis as the roll holding shaft, thereby pressing the raw material roll through the cylindrical member.

8. The method for mounting a raw material roll according to claim 7, wherein the raw material roll pressing step includes the step of inserting the cylindrical member into the roll holding shaft by the moving means.

9. The method for mounting a raw material roll according to claim 7 or 8, further comprising a second raw material roll pressing step, in which, after performing the raw material roll pressing step, the pressing member is moved in the detachment direction by the drive device, thereby pressing the raw material roll through the cylindrical member.

10. The method for mounting a raw material roll according to any one of claims 7 to 9, wherein the core tube insertion step includes a step of moving the rod-shaped member while maintaining a non-contact state with the roll holding shaft.

11. The method for mounting a raw material roll according to claim 8, wherein the raw material roll pressing step includes a step of moving the rod-shaped member while maintaining a non-contact state with the roll holding shaft.

12. A method for manufacturing a sheet product using the raw material roll mounting system described in any one of claims 1 to 6, The core tube insertion step involves moving the raw material roll, in which the rod-shaped member is inserted into the core tube, using the aforementioned moving means, and inserting the roll holding shaft into the core tube. After the core tube insertion step, the raw material roll pressing step is performed by moving the pressing member in the detachment direction using the drive device, thereby pressing the raw material roll. A method for manufacturing a sheet product, comprising: after performing the raw material roll pressing step, a raw material roll pressing step in which the rod-shaped member into which the cylindrical member is inserted is moved toward the roll holding shaft by the moving means while being positioned on the same axis as the roll holding shaft, thereby pressing the raw material roll through the cylindrical member.
