  However, in the cutting device of FIG. 7, the blade portion of the round blade cutter 101 comes into contact with the receiving surface 100 perpendicularly, and the blade portion of the round blade cutter 101 is worn early, so that the sheet-like member SE is smoothly cut. Therefore, there is a problem that it is necessary to polish the blade portion frequently.

  Further, in the cutting device of FIG. 8, the round blade cutter 111 is rotated to cut the sheet-like member SE. Therefore, when the sheet-like member SE made of unvulcanized rubber is cut by the round blade cutter 111, The round blade cutter 111 and the cut surface of the sheet-like member SE rub against each other, and rubber debris is generated from the cut surface of the sheet-like member SE, and the generated rubber debris adheres to surrounding devices.

  Furthermore, in the cutting device of FIG. 9, the round blade cutter 121 is pressed against the one end surface 120a of the receiving surface 120 by the cylinder 122, so that a space for providing the cylinder 122 in one axial direction of the round blade cutter 121 is required. For example, when a plurality of round blade cutters 121 are provided so as to be aligned in the axial direction, and each of the round blade cutters 121 cuts the sheet-like member SE at a plurality of positions in the width direction to form a plurality of strip-like members, the space is There is a problem that the interval between the round blade cutters 121 is increased by a necessary amount, and the width dimension of each belt-like member cannot be reduced.

  The present invention has been made in view of the above-mentioned problems, and the object of the present invention is to always perform smooth cutting without requiring polishing of the blade portion and to prevent occurrence of rubber debris. In addition, an object of the present invention is to provide a sheet-like member cutting device capable of reducing the width of each band-like member when the sheet-like member is cut at a plurality of positions in the width direction to form a plurality of band-like members.

  In order to achieve the above object, the present invention provides a sheet-shaped member cutting apparatus for cutting a sheet-shaped member made of unvulcanized rubber, wherein a rotatable disk-shaped member and an axial end surface of the disk-shaped member are provided. Provided on the outer peripheral surface over the entire circumference, inclined to the outer side in the radial direction and inclined to the other end surface in the axial direction, and provided so as to face the disk-shaped member in the radial direction, and in the form of a sheet on the outer peripheral surface A rotatable receiving roller with which one surface in the thickness direction of the member abuts, and a corner portion provided on the outer circumferential surface of the receiving roller so as to extend over the entire circumference and capable of abutting with the inclined surface of the disk-shaped member; It has.

  As a result, an inclined surface is provided over the entire circumference on the outer circumferential surface side of one end surface in the axial direction of the disk-shaped member, and one surface in the thickness direction of the sheet-shaped member is in contact with the outer circumferential surface of the receiving roller. Since the outer peripheral surface of the receiving roller is formed with corners that can contact the inclined surface of the disk-shaped member over the entire circumference, for example, the disk-shaped member is inclined at the corner of the receiving roller. When the receiving roller rotates while the surface abuts and the sheet-like member is in contact with the outer peripheral surface of the receiving roller, the sheet-like member is sandwiched between the disc-like member and the receiving roller, and the disc The sheet-like member rotates in synchronization with the receiving roller, and the sheet-like member passes between the disk-like member and the receiving roller. As a result, the sheet-like member is sandwiched between the inclined surface of the disk-like member and the corner of the receiving roller, and the sheet-like member is pressed against the corner of the receiving roller by the inclined surface of the disk-like member. The sheet-like member is cut by the corners of the rollers. Further, since the disk-shaped member rotates in synchronization with the receiving roller, the cut surface of the sheet-shaped member and the disk-shaped member do not rub unnecessarily. Further, since the inclined surface of the disk-shaped member is formed to be inclined toward the radially outer side toward the other end surface in the axial direction, the radial position between the disk-shaped member and the receiving roller can be adjusted. Thus, the inclined surface of the disk-shaped member and the corner of the receiving roller can be brought into contact with each other, and there is no need to adjust the position of the disk-shaped member in the axial direction in order to cut the sheet-shaped member.

  According to the present invention, since the sheet-like member can be cut by the corners of the receiving roller, for example, the disc-like member is composed of a round blade cutter, and the blade portion is provided on the outer peripheral surface of the disc-like member. Even in this case, it is possible to always cut smoothly without polishing the blade portion. Further, since the cut surface of the sheet-like member and the disc-like member are not rubbed unnecessarily, it is possible to prevent the occurrence of rubber debris. Further, since it is not necessary to adjust the position of the disk-like member in the axial direction in order to cut the sheet-like member, the disk-like member is moved in the axial direction to one side and the other side of the disk-like member. For example, when a plurality of disk-shaped members are provided so as to be aligned in the axial direction, the interval between the disk-shaped members can be reduced. Therefore, when a plurality of disk-shaped members are provided so as to be aligned in the axial direction, and the sheet-shaped member is cut at a plurality of positions in the width direction by each disk-shaped member to form a plurality of band-shaped members, The width dimension can be reduced.

There are storage devices that are wound and stored.

  The transport device 10 is formed of a well-known belt conveyor, and is configured to transport the sheet-like member SE supplied from the material supply device on the upper surface.

  The receiving roller 20 includes a plurality of pulleys 21 that are spaced apart from each other in the axial direction, and a shaft 22 that connects the pulleys 21 in the axial direction. The axial direction of the receiving roller 20 is orthogonal to the conveying direction of the conveying device 10, and the upper surface of each pulley 21 of the receiving roller 20 is disposed at a position slightly lower than the upper surface of the conveying device 10. In addition, a groove portion 21a extending over the entire circumference is provided on the outer peripheral surface of each pulley 21, and one opening edge portion in the axial direction of the groove portion 21a is formed in an acute angle, and the corner is formed by the one opening edge portion in the axial direction. A portion 21b is formed. The other opening edge portion in the axial direction of the groove portion 21a is formed in a curved shape, and a curved surface portion 21c is formed by the other opening edge portion in the axial direction. The shaft 22 is rotatable by a driving device such as a motor (not shown). That is, the sheet-like member SE sent out from the conveying device 10 contacts the upper surface of the receiving roller 20, and the receiving roller 20 rotates in the conveying direction of the conveying device 10, so that the sheet-like member SE on the receiving roller 20 is It is sent out to the conveying devices 40 and 50 side.

  Each disk-shaped member 30 consists of a round blade cutter, and each disk-shaped member 30 is provided at intervals in the axial direction. Each disk-shaped member 30 is disposed so as to face each pulley 21 of the receiving roller 20 in the radial direction, and is disposed above the groove portion 21 a of each pulley 21 of the receiving roller 20. One end surface side inclined surface 30 a is provided over the entire circumference on the outer peripheral surface side of the one end surface in the axial direction of the disk-shaped member 30, and the one end surface side inclined surface 30 a faces the radially outer side of the disk-shaped member 30. The disk-shaped member 30 is inclined toward the other end surface in the axial direction. In addition, the other end surface side inclined surface 30b is provided over the entire circumference on the outer peripheral surface side of the other end surface in the axial direction of the disk-shaped member 30, and the other end surface side inclined surface 30b is disposed on the radially outer side of the disk-shaped member 30. The disk-shaped member 30 is inclined toward the one end surface side in the axial direction. A blade portion is formed at a portion where the inclined surfaces 30a and 30b intersect.

  Each disk-shaped member 30 is rotatably supported by a support member 31, and each support member 31 is supported by one end of an arm 32. The support member 31 and one end of the arm 32 are coupled so as to be rotatable in the vertical direction. The other end of each arm 32 is connected to a frame tip 33 so as to be pivotable in the vertical direction, and each frame tip 33 is fixed to a frame body (not shown). A rod of a cylinder 34, which is a well-known air cylinder, is connected to an intermediate portion of each arm 32 so as to be rotatable in the vertical direction, and each cylinder 34 is fixed to the frame body. Each cylinder 34 can rotate each arm 32 in the vertical direction, and each disk-shaped member 30 moves in the vertical direction by the vertical rotation of each arm 32. That is, each cylinder 34 can move each disk-shaped member 30 in the vertical direction. When each disk-shaped member 30 is moved in the vertical direction by each cylinder 34, each disk-shaped member 30 is moved by the receiving roller 20. The pulleys 21 are moved in the radial direction. Further, when the disk-shaped member 30 is moved downward by the cylinder 34, the outer peripheral surface side of the disk-shaped member 30 is inserted into the groove portion 21a of the pulley 21, and the one end surface side inclined surface 30a of the disk-shaped member 30 is It abuts on the corner 21 b of the pulley 21. Further, when the one end surface side inclined surface 30 a of the disk-shaped member 30 comes into contact with the corner portion 21 b, a predetermined gap is provided between the other end surface side inclined surface 30 b of the disk-shaped member 30 and the curved surface portion 21 c of the pulley 21. It is supposed to be.

  Each of the conveying devices 40 and 50 includes a well-known belt conveyor, and conveys the sheet-like member SE that has passed between the receiving roller 20 and each disk-like member 30 in the same conveying direction as the conveying device 10. Yes. The upper conveying device 40 is disposed above the lower conveying device 50, the upper conveying device 40 is disposed above the upper surface of each pulley 21 of the receiving roller 20, and the lower conveying device 50 is disposed on each of the receiving rollers 20. It is arranged below the upper surface of the pulley 21.

  In the sheet-shaped member cutting device configured as described above, when cutting the sheet-shaped member SH supplied from the material supply device, first, each disk-shaped member 30 is moved downward by each cylinder 34. In addition, the outer peripheral surface side of each disk-shaped member 30 is inserted into the groove portion 21 a of each pulley 21 of the roller 20, and the one end surface-side inclined surface 30 a of each disk-shaped member 30 is used as the corner portion 21 b of each pulley 21. Make contact.

  Next, the sheet-like member SH supplied from the material supply device is conveyed by the conveying device 10, and the outer circumference of each pulley 21 of the roller 20 receives one surface in the thickness direction of the sheet-like member SH sent out from the conveying device 10. Make contact with the surface. Subsequently, while the conveying device 10 continues to convey the sheet-like member SH, the receiving roller 20 is rotated in the conveying direction of the conveying device 10, so that the sheet-like member SH has each pulley 21 and each disk of the receiving roller 20. It is inserted between the shaped member 30. When the receiving roller 20 is further rotated in this state, each disk-shaped member 30 rotates in synchronization with the receiving roller 20 and a sheet-like shape is formed between each pulley 21 of the receiving roller 20 and each disk-shaped member 30. The member SH passes. As a result, the sheet-like member SH is sandwiched between the one-end-surface-side inclined surface 30 a of the disc-shaped member 30 and the corner portion 21 b of the pulley 21, and the sheet-like member SH is inclined to the one-end-surface-side of the disc-shaped member 30. The surface 30a is pressed against the corner 21b of the pulley 21, and the sheet-like member SE is cut by the corner 21b. That is, the sheet-like member SE is cut by the corners 21b of the pulleys 21 to form a plurality of belt-like members BE.

  Here, when the one end surface side inclined surface 30 a of the disk-like member 30 abuts on the corner portion 21 b of the pulley 21, the other end surface side inclined surface 30 b of the disk member 30 and the curved surface portion 21 c of the pulley 21 are interposed. A predetermined gap is generated. For this reason, when the sheet-like member SH is cut by the corner portion 21b, a part of the sheet-like member SH is between the other end surface side inclined surface 30b of the disk-like member 30 and the curved surface portion 21c of the pulley 21. It is caught. Therefore, the one end surface side inclined surface 30a of the disk-like member 30 is pressed against the corner portion 21b by the reaction force of the sandwiched sheet-like member SH (see FIG. 4).

  Further, when the width L of the groove 21a of the pulley 21 is set to ¼ or more and ３ or less of the thickness t of the sheet-like member SH, the sheet-like member SH tends to be cut smoothly. That is, it is preferable that the width L of the groove 21a of the pulley 21 is set to ¼ or more and 以下 or less of the thickness t of the sheet-like member SH (see FIG. 4).

  On the other hand, when changing the width dimension of each band-shaped member BE formed from the sheet-shaped member SH, a part of the disk-shaped members 30 among the disk-shaped members 30 is moved upward by the cylinder 34. For example, in FIG. 2, by moving each disk-shaped member 30 upward every other arrangement direction, the width dimension of each band-shaped member BE formed from the sheet-shaped member SH can be doubled.

  Each belt-like member BE is sent out from the receiving roller 20 in a state of being arranged in the width direction of the sheet-like member SH. Further, each belt member BE is transported by the lower transport device 50 every other arrangement direction, and the other belt members BE are transported by the upper transport device 40. Thereby, each strip | belt-shaped member BE can be conveyed, without mutually sticking. Each strip member BE is supplied to an extrusion device (not shown), and a predetermined unvulcanized rubber member is formed.

  As described above, according to the present embodiment, the one end surface side inclined surface 30a is provided over the entire circumference on the outer peripheral surface side of the axial end surface of the disk-shaped member 30, and each pulley 21 of the receiving roller 20 is provided. The outer peripheral surface is formed so that one surface in the thickness direction of the sheet-like member SH abuts, and the outer peripheral surface of the pulley 21 of the receiving roller 20 is provided with a corner portion 21b over the entire circumference, and the corner portion 21b is Since one end surface side inclined surface 30a of the disk-shaped member 30 can be contacted, the one end surface side inclined surface 30a of the disk-shaped member 30 contacts the corner portion 21b and each pulley 21 of the receiving roller 20 is in contact with each other. When the receiving roller 20 is rotated in a state where the sheet-like member SH is in contact with the outer peripheral surface, the sheet-like member SH is sandwiched between the disc-like member 30 and the pulley 21 of the receiving roller 20, and the disc Shaped member 30 Rotate synchronously with La 20, the sheet-like member SH passes between the pulley 21 of the disk-shaped member 30 and the receiving roller 20. Accordingly, the sheet-like member SH is sandwiched between the corner portion 21b of the pulley 21 and the one-end-surface-side inclined surface 30a of the disc-like member 30, and the sheet-like member SH is inclined on the one-end-surface-side of the disc-like member 30. The sheet 30 is pressed against the corner 21b by the surface 30a, and the sheet-like member SH is cut by the corner 21b. Therefore, the disk-shaped member 30 is formed of a round blade cutter, and the blade portion is provided on the outer peripheral surface of the disk-shaped member 30. However, the blade portion is not required to be polished, and smooth cutting can always be performed.

  Further, since the disk-shaped member 30 rotates in synchronization with the receiving roller 20, the cut surface of the sheet-shaped member SH and the disk-shaped member 30 are not rubbed unnecessarily, and generation of rubber debris is prevented. Can do.

  Furthermore, since the one end surface side inclined surface 30a of the disk-shaped member 30 is formed so as to be inclined toward the radially outer side toward the other axial end surface side, the radial direction between the disk-shaped member 30 and the pulley 21 is increased. By adjusting the position, the one end surface side inclined surface 30a of the disc-like member 30 and the corner portion 21b of the pulley 21 can be brought into contact with each other, and the disc-like member is used for cutting the sheet-like member SH. There is no need to adjust the position of 30 in the axial direction. That is, it is not necessary to provide a device for moving the disk-shaped member 30 in the axial direction on one and the other side of the disk-shaped member 30, and a plurality of disk-shaped members 30 are provided so as to be aligned in the axial direction. The distance between the disk-shaped members 30 can be reduced. Therefore, when a plurality of disk-shaped members are provided so as to be aligned in the axial direction and the sheet-shaped member SH is cut at a plurality of positions in the width direction to form the plurality of band-shaped members BE, the width dimension of each band-shaped member BE is set. Can be small.

  Further, since the disk-shaped member 30 is constituted by a round blade cutter, when the sheet-shaped member SH is sandwiched between the disk-shaped member 30 and the pulley 21, the outer peripheral surface side of the disk-shaped member 30 is the sheet-shaped member. It is easy to bite into SH, which is advantageous in reducing cutting resistance.

  Further, a groove portion 21a extending over the entire circumference is provided on the outer peripheral surface of the pulley 21 of the receiving roller 20, and the groove portion 21a is formed so that the outer peripheral surface side of the disk-shaped member 30 is inserted. Since the corner portion 21b is formed by the opening edge portion, the corner portion 21b that can come into contact with the inclined surface 30a on the one end surface side of the disc-like member 30 can be easily formed on the outer peripheral surface of the pulley 21. This is advantageous in reducing the manufacturing cost.

  Further, when the curved surface portion 21c is formed by the other opening edge portion in the axial direction among the opening edge portions of the groove portion 21a of the pulley 21, and the one end surface side inclined surface 30a of the disc-like member 30 is in contact with the corner portion 21b. Since the predetermined gap is provided between the inclined surface 30b on the other end surface side of the disk-shaped member 30 and the curved surface portion 21c, the disk is cut when the sheet-shaped member SH is cut by the corner portion 21b. Part of the sheet-like member SH is sandwiched between the other end surface side inclined surface 30 b of the member 30 and the curved surface portion 21 c of the pulley 21. That is, the disc-like member 30 is pressed against the corner portion 21b by the reaction force of the sandwiched sheet-like member SH, and the contact between the one end side inclined surface 30a and the corner portion 21b of the disc-like member 30 is ensured. Can be maintained. Further, since the force with which the one end surface side inclined surface 30a is pressed against the corner portion 21b is generated by the reaction force of the sandwiched sheet-like member SH, the force with which the one end surface side inclined surface 30a is pressed against the corner portion 21b becomes unnecessarily large. This is advantageous in preventing wear of the corner 21b.

  A plurality of the disk-shaped members 30 are provided at intervals in the axial direction, and a plurality of corner portions 21b corresponding to the respective disk-shaped members 30 are provided on the receiving rollers 20, and the disk-shaped members 30 are received on the receiving rollers. Since each of the disk-shaped members 30 is configured to be movable in the radial direction, the disk-shaped member 30 is formed from the sheet-shaped member SH by bringing the disk-shaped member 30 into contact with the corner 21b of the pulley 21. The width dimension of each belt-like member BE to be changed can be changed. That is, the width dimension of each belt-like member BE can be easily changed, which is advantageous in improving productivity.

  In the present embodiment, the receiving roller 20 is provided with a plurality of pulleys 21 and each pulley 21 is provided with a corner 21b. However, as shown in FIG. It is also possible to provide 60. In this case, the receiving roller 60 is formed in a cylindrical shape, and a plurality of groove portions 60 a are formed on the outer peripheral surface of the receiving roller 60, and each groove portion 60 a is formed to extend over the entire circumference of the receiving roller 60. Yes. The groove portions 60 a are provided at intervals in the axial direction of the receiving roller 60, and are provided at positions corresponding to the respective disk-like members 30. The groove portion 60 a can be inserted on the outer peripheral surface side of the disk-shaped member 30. One opening edge in the axial direction of the groove 60a is formed in an acute angle shape, and a corner 60b is formed by the one opening edge in the axial direction. The other opening edge in the axial direction of the groove 60a is formed in a curved shape, and a curved surface 60b is formed by the other opening edge in the axial direction.

  Therefore, even when the receiving roller 60 is provided in place of the receiving roller 20, the sheet-like member SH is obtained by bringing the inclined surface 30a on the one end surface side of each disk-like member 30 into contact with each corner 60b of the roller 60. Can be cut.

  In the present embodiment, a plurality of disk-shaped members 30 made of a round blade cutter are provided. However, a plurality of disk-shaped members 70 can be provided instead of each disk-shaped member 30. is there. In this case, the outer peripheral surface of each disk-shaped member 70 is formed in a curved surface shape. Further, an inclined surface 70 a is provided over the entire circumference on the outer peripheral surface side of one axial end surface of each disk-shaped member 70, and the inclined surface 70 a is disk-shaped toward the radially outer side of the disk-shaped member 70. The member 70 is inclined toward the other end surface in the axial direction. The inclined surface 70 a of the disk-like member 70 can contact the corner portion 21 b of the pulley 21.

  Therefore, even when each disk-like member 70 is provided in place of each disk-like member 30, by bringing the inclined surface 70a of each disk-like member 70 into contact with each corner 21b, the sheet-like member SH Cutting can be done.

  In the present embodiment, the receiving roller 20 is rotated by the driving device. However, the sheet-like member SH can be cut without providing a driving device for rotating the receiving roller 20. is there. In this case, each belt-like member BE that has passed between the receiving roller 20 and each disk-like member 30 is conveyed by the conveying devices 40 and 50, so that the sheet-like member SH sent from the conveying device 10 is sequentially received by the receiving rollers. The sheet-like member SH is cut between the disc-like members 30 and 20.
