Is held in a state of being granted. Therefore, the belt 100 can be stably held. Furthermore, it is easy to insert the two pulleys 91 and 92 on the inner peripheral side of the belt 100. In addition, the belt 100 can be easily retracted from the two pulleys 91 and 92 while being held.

Second Embodiment
A second embodiment of the present invention will be described. However, about the thing which has the structure similar to the said embodiment, the description is abbreviate | omitted suitably using the same code | symbol.
The belt detaching apparatus 201 of the present embodiment is used particularly when the processing machine is a cutting apparatus that cuts the belt 100 having a rectangular cross section into a V-shaped cross section. In this cutting device, while running the belt 100 mounted on the two pulleys 91 and 92, both ends of the belt 100 are cut by a cutter or the like, thereby forming a V-belt 100a having a V-shaped cross section. By this cutting, two ring scraps 100b having a width smaller than that of the V belt 100a are formed on both sides of the V belt 100a. The belt detaching apparatus 201 of the present embodiment is detached from the two pulleys 91 and 92 in addition to detaching the belt 100 from and to the two pulleys 91 and 92 of the cutting apparatus, as in the first embodiment. The V belt 100a and the ring scrap 100b can be separated and collected.

  As shown in FIG. 5, the belt detaching device 201 includes a belt push-out means 60 provided on the base 27 and a separation / collection assisting device 70 in addition to the configuration of the belt detaching device 1 of the first embodiment. The belt push-out means 60 has a cylinder 62 attached to the base 27 and a push plate (push member) 61 fixed to a rod 62a of the cylinder 62.

  The cylinder 62 is provided between the base 23 and the base 25. That is, the cylinder 62 is disposed between the pair of sandwiching bars 17 and 19 and the pair of support bars 13 and 15. The pusher plate 61 is attached to a rod 62a of the cylinder 62, and the pusher plate 61 is driven in the front-rear direction by operating the cylinder 62.

  The separation collection assisting device 70 includes a pedestal portion 71 to which wheels 73 are attached, a vertically extending column 72 fixed to the pedestal portion 71, a belt collection bar 74 protruding from the column 72, and a pedestal portion 71. And a ring waste collection box 75 disposed on the upper surface. The belt collection bar 74 extends while inclining upward toward the tip side.

Next, the operation of the belt detaching apparatus 201 will be described.
The procedure of attaching the belt 100 to the two pulleys 91 and 92 and the procedure of removing the V belt 100a and the ring waste 100b from the two pulleys 91 and 92 are the same as the procedure described in the first embodiment.
Hereinafter, a procedure for separating and collecting the V belt 100a and the ring waste 100b after removing the V belt 100a and the ring waste 100b from the two pulleys 91 and 92 will be described.

[Separation process]
As shown in FIG. 6 (a), from the state in which the V belt 100a and the ring waste 100b are held by the support bars 10, 11, 13, 15 and the sandwiching bars 17 and 19, FIG. 6 (b) and FIG. 6 (c). As shown, the support bars 10, 11 are brought close together and then lowered. Since the V-belt 100a is held by the holding bars 17 and 19, the shape in which the center portion is constricted is maintained. On the other hand, the ring scrap 100b is smaller in width and lower in rigidity than the V-belt 100a. Therefore, when the support by the support bars 10 and 11 is lost, the shape of the ring scrap 100b cannot be maintained. The position is lower than the upper end of 100a. In FIG. 6 (c), the ring waste 100b is lowered together with the support bars 10 and 11, but as shown in FIG. May be at a position lower than the upper end of the V-belt 100a.

[Belt collection bar insertion process]
Next, the separation collection assisting device 70 is moved by the wheels 73, and as shown in FIGS. 6 (d) and 5, the inner peripheral side of the V-belt 100a is positioned above the support bars 10, 11. Insert the belt collection bar 74.

[Separate collection process]
When removing the V belt 100a and the ring scrap 100b from the two pulleys 91 and 92, the rod 62a is contracted in advance, and as shown in FIG. 5, the rear of the V belt 100a and the ring scrap 100b (base 27 side). In addition, the extrusion plate 61 is arranged. The extrusion plate 61 is moved forward by the cylinder 62, and the V belt 100a and the ring waste 100b are pushed forward. As a result, the V-belt 100a is recovered by the belt recovery bar 74, and the ring waste 100b falls into the ring waste recovery box 75. As described above, the V belt 100a and the ring scrap 100b can be automatically separated and collected.

  Further, since the belt collection bar 74 is inclined upward and extends toward the front end side, the V-belt 100a suspended from the belt collection bar 74 is along the belt collection bar 74 in FIG. Automatically slides forward. Therefore, a plurality of V belts 100 a can be suspended from the belt collection bar 74. Therefore, it is not necessary to remove the V-belt 100a from the belt collection bar 74 every time the collection and collection work is completed, so that the collection and collection work can be performed continuously. Therefore, the collection operation can be performed more efficiently.

  The second embodiment described above can be implemented with the following modifications.

  In the above embodiment, in the separation step, the support bars 10 and 11 are lowered from the state shown in FIG. 6A and then lowered (see FIGS. 6B and 6C). Depending on the position where the belts 100 and 11 are in contact with each other and the characteristics (peripheral length and rigidity) of the belt 100, the support bars 10 and 11 may be lowered without being brought close to each other.

  In the said embodiment, although the extrusion board 61 is arrange | positioned in the position between the clamping bars 17 and 19 and the support bars 13 and 15 regarding an up-down direction, it can extrude the V belt 100a and the ring waste 100b ahead. If it is a position, it is not limited to this.

  In the said embodiment, although both the base stand 28 and the base part 71 are movable by a wheel, the base part 71 may be immovable.

  The support column 72 may be rotatably attached to the pedestal portion 71. With this configuration, when removing the V-belt 100a suspended from the belt collection bar 74, it is possible to remove the V belt 100a from the belt collection bar 74 by simply rotating the column 72 without moving the pedestal 71 or the base table 28 by the wheel. The operation of removing the belt 100a can be performed. Therefore, the collection operation can be performed more efficiently.

  When the support columns 72 are rotatably attached to the pedestal portion 71, as shown in FIG. 8, a plurality of (four in FIG. 8) belt recovery bars 74 are radially formed on the support columns 72 as viewed from above. It may be attached. With this configuration, after collecting the V-belt 100a on the belt collecting bar 74, the column 72 is suspended by the belt collecting bar 74 by rotating the column 72 by a predetermined angle (for example, 90 degrees in the case of FIG. 8). At the same time that the V belt 100a is removed from the belt recovery bar 74, the V belt 100a can be newly recovered to another belt recovery bar 74. Therefore, the collection operation can be performed more efficiently. In FIG. 8, the number of belt collection bars 74 is four, but may be three or less or five or more.

  The belt collection bar 74 may extend in the horizontal direction.

  Further, the belt recovery bar 74 may be provided on the base 27. Specifically, the belt recovery bar 74 is provided on the base 27 so as to be movable in its axial direction (in the front-rear direction when the belt recovery bar 74 extends horizontally). A configuration in which means (for example, a cylinder) for moving the bar 74 in the axial direction thereof is installed may be used.

  The means for driving the extrusion plate 61 in the front-rear direction is not limited to the cylinder 62. For example, the extrusion plate 61 may be driven in the front-rear direction by a motor using a ball screw or the like extending in the front-rear direction.

  The extrusion plate 61 may be fixed to the base 27, and the bases 21, 23, and 25 may be driven in the front-rear direction with respect to the base 27 by driving means such as cylinders.

  Further, the belt pushing means 60 is not necessarily provided on the base 27. Like the separation collection assisting device 70, the base 27 may be a separate body.

  The cutting device is not limited to the cutting device for forming the V belt as long as it cuts at least one end of the belt 100 to form ring scraps having a considerably smaller width than the belt 100.

  Next, modified embodiments in which various modifications are made to the first and second embodiments will be described. However, about the thing which has the structure similar to the said embodiment, the description is abbreviate | omitted suitably using the same code | symbol.

1] When removing the belt 100 from the protruding bar 82, after inserting the support bars 10, 11, 13, 15 on the inner peripheral side of the belt 100 and arranging the holding bars 17, 19 on the outer peripheral side of the belt 100, The following procedure may be used.
As shown in FIG. 9A, the belt 100 suspended from the protruding bar 82 has an elliptical shape. As shown in FIG. 9B, the support bars 10 and 11 are separated from each other, and the support bars 13 and 15 are also separated and brought into contact with the inner peripheral surface of the belt 100, and then as shown in FIG. 9C. Further, the holding bars 17 and 19 are brought close to each other, and the central portion of the belt 100 is pressed from the outer peripheral side by the holding bars 17 and 19. As a result, the belt 100 is deformed into a constricted shape (gourd shape) at the center, so that the position of the upper end of the belt 100 rises and the belt 100 moves away from the protruding bar 82. At this time, since the belt 100 is supported from the inner peripheral side by the support bars 10, 11, 13, and 15, it is possible to prevent the sandwiching bars 17 and 19 and the belt from sliding. Thereafter, the belt detaching device 1 is retracted from the belt supply device 80, and then the support bars 10, 11, 13, and 15 are moved to apply tension to the belt 100 as shown in FIG.

2] When removing the belt 100 (or the V belt 100a and the ring scrap 100b) from the two pulleys 91 and 92, in the above embodiment, after the pulley 92 is raised in the belt holding step, the clamping bars 17 and 19 are moved. However, the holding bars 17 and 19 may be brought close to each other at the same time when the pulley 92 is raised. As a result, the belt 100 is always in a state where a tension is applied, so that it is possible to prevent positional deviation due to slack.

3] The sandwiching bars 17, 19 and the support bars 10, 11, 13, 15 may be configured to be relatively movable in the front-rear direction. Specifically, for example, the base 25 may be provided so as to be movable in the front-rear direction with respect to the base 27, and may include a means (cylinder or the like) for driving the base 25 in the front-rear direction.
In the case of this configuration, after removing the belt 100 from the protruding bar 82, the belt 100 can be attached to the two pulleys 91 and 92 by the following procedure.

  As shown in FIG. 10A, two pulleys 91 and 92 are inserted on the inner peripheral side of the belt 100 held by the belt detaching device. At this time, the distance between the support bars 10 and 11 (the distance between the support bars 13 and 15) is larger than the diameter of the pulley 91 (92). Thereafter, as shown in FIG. 10B, the support bars 10 and 11 are lowered and the support bars 13 and 15 are raised to loosen the tension of the belt 100. At this time, since the belt 100 is pressed and clamped by the clamping bars 17 and 19 at the center in the vertical direction, the belt 100 is maintained in a shape in which the upper and lower ends are swollen. Therefore, even if the distance between the pair of support bars 10 and 11 (13 and 15) is larger than the diameter of the pulley, the pair of support bars 10 and 11 (13 and 15) can be in a state of receiving little force from the belt 100.

  Next, as shown in FIG. 10C, only the support bars 10, 11, 13, and 15 are retracted from the inner peripheral side of the belt 100. As described above, since the support bars 10, 11, 13, and 15 receive almost no force from the belt 100, they can be retracted without being caught by the inner peripheral surface of the belt 100. Then, as shown in FIG.10 (d), the clamping bars 17 and 19 are spaced apart. At the same time, the pulley 92 is lowered to apply tension to the belt 100. By attaching the belt 100 to the pulley in this procedure, the step of bringing the support bar 10 and the support bar 11 close to each other and the step of bringing the support bar 13 and the support bar 15 close to each other can be omitted.

4] In the first and second embodiments, the belt 100 is acquired by removing the belt 100 suspended from the protruding bar 82 from the protruding bar 82. However, the method of acquiring the belt 100 is limited to this. Is not to be done. For example, the belt supply device 80 shown in FIG. 2 may be changed as follows. Without providing the protruding bar 82, the support bars 10 and 11 that are brought closest to each other are arranged at the position of the protruding bar 82, and the plurality of belts 100 suspended from the hanger 81 by the push plate 83 are arranged on the front end side of the hanger 81. The leading edge belt 100 may be dropped along the inclined surface of the tip of the hanger 81 and hooked on the support bars 10 and 11.

5] In the first and second embodiments, the support bars 10, 11, 13, 15 and the sandwiching bars 17, 19 are driven in the vertical direction or the horizontal direction by a motor using a ball screw or the like. However, the means for driving the support bars 10, 11, 13, 15 and the sandwiching bars 17, 19 are not limited to motors, and may be cylinders, for example.

6] In the first and second embodiments, an operator pushes or pulls the belt detaching device 1, 201 to move the wheel 50 to move the belt detaching device 1, 201. A driving means such as a cylinder may be attached to the base 27 so that the belt detaching devices 1 and 201 can be automatically moved.

7] In the first and second embodiments, after the belt 100 is mounted on the processing machine, the support bar and the clamping bar are once retracted from the processing machine, and after the processing by the processing machine is completed, the support bar is again used. However, depending on the type of the processing machine, after the belt 100 is mounted, the support bar or the clamping bar may be left as it is without being retracted.

8] The base 27 may be attached to the base table 28 so as to be rotatable about a vertical axis. Accordingly, since it is not necessary to move the base base 28 in order to change the direction of the belt detaching apparatus 1, the movement from the belt supplying apparatus 80 to the processing machine may be changed depending on the installation location of the belt supplying apparatus 80 and the processing machine. Can be done efficiently.

9] In the first and second embodiments, the two pulleys 91 and 92 are arranged side by side in the vertical direction. However, the processing machine in which the two pulleys 91 and 92 are arranged side by side in the horizontal direction or the oblique direction. The base 27 may be configured to be rotatable about an axis in the front-rear direction.
