Japanese Patent No. 315528

  In the apparatus of Patent Document 1 described above, when the belt sleeve is transported to the processing apparatus side, the belt sleeve is only hung on the support member, and therefore the belt sleeve falls from the support member during transport. There is a fear. Further, the shape of the belt sleeve just hung on the support member is not stable, and an error in insertion into the shaft of the processing apparatus is likely to occur due to a change in the opening shape of the belt sleeve during the conveyance.

  An object of the present invention is to provide a belt sleeve transport device and a transport method that can reliably transport and mount the belt sleeve to the processing apparatus.

Means for Solving the Problems and Effects of the Invention

A hanger that suspends the belt sleeve, a pair of sleeve holding means that are pressed against both side surfaces of the belt sleeve suspended on the hanger and sandwich the belt sleeve, and the pair of sleeve holding means And a moving means for moving the belt sleeve in the cylinder axis direction.

  When a pair of sleeve holding means is pressed against both side surfaces of the belt sleeve suspended from the hanger, the belt sleeve is deformed, and at the same time, a repulsive force is generated to spread the belt sleeve to its original shape. Therefore, the belt sleeve and the sleeve holding means are brought into pressure contact with each other, and the belt sleeve is securely held by the pair of sleeve holding means. In addition, since both sides of the belt sleeve are held down by the pair of sleeve holding means, the shape of the sleeve is stabilized. Accordingly, it is possible to prevent the belt sleeve from being dropped during conveyance, and to reliably attach the processing apparatus to the shaft.

  According to a second aspect of the present invention, there is provided the belt sleeve conveying apparatus according to the first aspect, wherein the sleeve holding means is a roll configured to be rotatable, and the pair of rolls are moved up and down while maintaining a horizontal posture. Means are further provided.

  According to this configuration, the pair of rolls as the sleeve holding means is kept in a horizontal posture, and the pair of rolls is simply moved down from the upper side of the belt sleeve suspended on the hanger to the lower side of the hanger. Can be pressed against both sides of the sleeve. It is possible to sandwich the belt sleeve by arranging the pair of rolls so as to sandwich the belt sleeve and then bringing the pair of rolls close to each other (changing the separation distance). Compared to the case, in the present invention, the configuration for bringing the pair of rolls into and out of contact with each other is unnecessary, and thus the configuration of the apparatus is simplified. Further, since each roll is configured to be rotatable, the roll can be smoothly lowered to the lower side of the hanger while rotating while the pair of rolls are in contact with both side surfaces of the belt sleeve.

  According to a third aspect of the present invention, there is provided the belt sleeve conveying apparatus according to the second aspect, further comprising a locking unit that locks the pair of rolls so as not to rotate.

  According to this configuration, the belt sleeve is dropped when the belt sleeve is removed from the hanger by locking the roll in a non-rotatable state by the locking means while the pair of rolls sandwich the belt sleeve. Can be prevented.

  According to a fourth aspect of the present invention, there is provided the belt sleeve conveying apparatus according to any one of the first to third aspects, wherein the sleeve holding means is covered with a vulcanized rubber.

  According to this configuration, the friction acting between the pair of sleeve holding means and the side surfaces of the belt sleeve is increased, and the clamping force of the pair of sleeve holding means is increased, so the belt sleeve is removed from the hanger. Sometimes, the belt sleeve can be prevented from falling.

  The belt sleeve conveying device according to a fifth aspect of the present invention is the belt sleeve conveying device according to any one of the first to fourth aspects, wherein the belt sleeve is pressed against both side surfaces of the belt sleeve sandwiched by the pair of sleeve holding means. A pair of press plates for correcting the shape of the belt sleeve is provided.

  When a belt sleeve held by a pair of sleeve holding means is to be attached to the processing apparatus, such as when the belt sleeve has a deformed ridge or when the belt sleeve bulges sideways, the belt sleeve The mounting may be difficult due to interference with the shaft of the processing apparatus and surrounding members. In the present invention, the pair of press plates is pressed against both side surfaces of the belt sleeve, so that the shape of the belt sleeve is corrected to a shape that can be mounted on the shaft of the processing apparatus. Can be performed reliably.

The sleeve has a sleeve pressing portion that comes into contact with an end surface of the sleeve opposite to the shaft of the processing apparatus.

  When the belt sleeve is thin and flexible, the holding ability of the belt sleeve is reduced only by a pair of sleeve holding means that sandwich the belt sleeve. In this case, even if the sleeve holding means moves toward the axis of the processing apparatus in the direction of the cylinder axis of the belt sleeve, since the holding ability is low, the sleeve holding means can be attached to the belt sleeve only by slightly contacting the shaft. On the other hand, the belt sleeve may move relatively, and the belt sleeve may not be stably mounted on the shaft of the processing apparatus. However, according to the present invention, since the belt sleeve holding means has the sleeve pressing portion that contacts the end surface of the belt sleeve opposite to the shaft of the processing apparatus, the belt sleeve is attached to the shaft when the belt sleeve is mounted. Since the sleeve holding means and the belt sleeve are integrally moved toward the shaft of the processing apparatus, the belt sleeve can be stably attached to the shaft of the processing apparatus.

A belt sleeve transport method according to a seventh aspect of the invention is a belt sleeve transport method in which a cylindrical belt sleeve is opened and transported to a processing apparatus and attached to a shaft of the processing apparatus.

It is characterized by.

  When a pair of sleeve holding means is pressed against both side surfaces of the belt sleeve suspended from the hanger, the belt sleeve is deformed, but at the same time, a repulsive force is generated to spread the belt sleeve to its original shape. Therefore, the belt sleeve and the sleeve holding means are brought into pressure contact with each other, and the belt sleeve is securely held by the pair of sleeve holding means. Further, the pair of sleeve holding means is pressed against both side surfaces of the belt sleeve, so that both side portions of the belt sleeve are suppressed, so that the shape of the sleeve is stabilized. Accordingly, it is possible to prevent the belt sleeve from being dropped during conveyance, and to reliably attach the processing apparatus to the shaft.

  According to an eighth aspect of the present invention, there is provided the belt sleeve transport method according to the seventh aspect, wherein a pair of presser plates are pressed against both side surfaces of the belt sleeve sandwiched by the pair of sleeve holding means. A shape correcting step for correcting the shape of the belt sleeve is provided.

  Attach the belt sleeve held by a pair of sleeve holding means to the processing device when the belt sleeve is deformed or when the belt sleeve bulges horizontally and the vertical length is shortened. In this case, the belt sleeve may interfere with the shaft of the processing apparatus and surrounding members, making it difficult to mount. In the present invention, the pair of press plates is pressed against both side surfaces of the belt sleeve, so that the shape of the belt sleeve is corrected to a shape that can be mounted on the shaft of the processing apparatus. Can be performed reliably.

  Next, an embodiment of the present invention will be described. FIG. 1 is a side view of a belt sleeve conveying apparatus according to the present embodiment. For the convenience of the following description, the left side in FIG. 1 is defined as the front and the right side in FIG. 1 is defined as the rear.

  The belt sleeve 100 handled by the belt sleeve conveying apparatus 1 according to the present embodiment further heats and pressurizes an unvulcanized belt sleeve 100 obtained by winding an unvulcanized rubber sheet and a core wire around the outer periphery of a mold. This is a vulcanized belt sleeve 100 manufactured as described above. As the rubber constituting the belt sleeve 100, ethylene-α-olefin elastomer, natural rubber, styrene-butadiene rubber, chloroprene rubber, hydrogenated nitrile rubber, or the like can be used.

  As shown in FIG. 1, a belt sleeve supply device 2 that supplies a vulcanized belt sleeve 100 is disposed behind the belt sleeve conveyance device 1. The belt sleeve supply device 2 includes a plurality of arms 3, and the plurality of arms 3 holds the cylindrical belt sleeve 100 with both ends thereof opened in the front-rear direction, and a plurality of arms. 3 is moved forward (in the cylinder axis direction of the belt sleeve 100), and the belt sleeve 100 is supplied to the belt sleeve conveying device 1.

  Further, in front of the belt sleeve conveying device 1, a processing device 4 that performs various processing on the belt sleeve 100 (for example, a polishing machine that polishes the surface of the belt sleeve 100, or the belt sleeve 100 into an annular belt having a predetermined width). A cutter device or the like for cutting) is arranged. In addition, the processing apparatus 4 usually has two shafts (a driving roll 5 and a driven roll 6) on which a belt sleeve 100 to be processed is wound and the belt sleeve 100 is caused to travel.

  The belt sleeve 100 of the present embodiment conveys the vulcanized belt sleeve 100 supplied from the belt sleeve supply device 2 to the processing device 4 with both ends open, and the two shafts of the processing device 4 5 and 6 are attached.

  Next, the belt sleeve conveyance device 1 will be described in detail. As shown in FIG. 1, the belt sleeve conveying device 1 includes two hangers 10 for suspending a belt sleeve 100, a fixed frame 11, and a pair provided on the fixed frame 11 so as to be movable in the front-rear direction and the vertical direction. The sleeve holding roll 12 is provided.

  Each hanger 10 is a cylindrical member, and the ends of two hangers 10 arranged horizontally are connected by a connecting member 13. A vertical shaft 14 is connected to the connecting member 13, and a motor 15 that rotationally drives the vertical shaft 14 is provided at the upper end of the vertical shaft 14. Therefore, when the vertical shaft 14 is rotationally driven by the motor 15, the two hangers 10 are rotated in a horizontal plane. Then, by rotating the two hangers 10 180 degrees, the position of the two hangers 10 receives the belt sleeve 100 from the belt sleeve supply device 2 (the position on the right side in FIG. 1) and the belt to the processing device 4. The position is switched between the positions where the sleeve 100 is delivered (the position on the left side in FIG. 1).

  The fixed frame 11 is installed at the height position of the upper end portion of the vertical shaft 14. A front and rear movable frame 16 that is movable in the front-rear direction along the guide rail 15 is provided at the lower portion of the fixed frame 11. The fixed frame 11 is also provided with a cylinder 17 for driving the front and rear movable frame 16 in the front and rear direction.

  The front and rear movable frame 16 has a vertical frame member 18 extending in the vertical direction, and the vertical frame member 18 is provided with a lifting frame 20 that can be moved up and down along the guide rail 19. In addition, the vertical frame member 18 is provided with a cylinder 21 that drives the lifting frame 20 up and down.

  The elevating frame 20 includes a first elevating frame member 22 extending in the horizontal direction and a second elevating frame member 23 connected to the front end of the first elevating frame member 22 and extending in the vertical direction. A pair of sleeve holding rolls 12 that sandwich the belt sleeve 100 is supported at the lower end of the second elevating frame member 23 in a horizontal position (an attitude in which the axis of the roll 12 is parallel to the horizontal direction (front-rear direction)). ing.

  The pair of sleeve holding rolls 12 move in the front-rear direction with respect to the fixed frame 11 when the front-rear movable frame 16 is driven back and forth by the cylinder 17 (moving means), and further, the cylinder 21 (lifting means) As a result, the elevating frame 20 is moved up and down with respect to the fixed frame 11 by being driven up and down.

  2 is a view taken along the line II-II in FIG. As shown in FIGS. 1 and 2, the pair of sleeve holding rolls 12 are arranged in a horizontal position extending parallel to the hanger 10 (front-rear direction) so as to sandwich the hanger 10 in a top view. The length of the pair of sleeve holding rolls 12 is substantially the same as the length of the hanger 10, and the distance between the pair of sleeve holding rolls 12 is slightly larger than the outer diameter of the hanger 10. As shown in FIG. 2, the surface of each sleeve holding roll 12 is covered with vulcanized rubber 25.

  Each of the pair of sleeve holding rolls 12 is rotatably supported by a bearing 26 at the lower end portion of the second elevating frame member 23. Further, the pair of sleeve holding rolls 12 includes various means of locking means. It is possible to lock in a non-rotatable manner. For example, in FIG. 2, each pair of sleeve holding rolls 12 is provided with a hole 12a penetrating in the radial direction, and a pin 27 (locking means) is inserted into the hole 12a. Is locked non-rotatably. The locking means is not limited to the pin 27 as shown in FIG. 2, but for example, a brake pad that frictionally contacts the surface of the sleeve holding roll 12 to prevent rotation, or the roll 12 is gripped from the outside in the radial direction. Various configurations other than the pin 27 such as a gripping member that stops rotation can be employed.

  Next, the operation of the above-described belt sleeve conveyance device 1 when conveying the belt sleeve will be described.

  First, in a state where the belt sleeves 100 are hung on the plurality of arms 3 of the belt sleeve supply device 2, as the plurality of arms 3 advance forward, as shown in FIG. The belt sleeve 100 is passed from the arm 3 to one hanger 10a located at the right side in the figure, and the belt sleeve 100 is suspended from the hanger 10a.

  In this state, as shown in FIG. 4, the belt 15 is suspended by rotating the vertical shaft 14 by the motor 15 and rotating the two hangers 10 supported by the vertical shaft 14 180 degrees in the horizontal plane. The hanger 10a is moved to a position for transferring the belt sleeve 100 to the processing device 4 (a position on the left side in the drawing).

  Next, as shown in FIG. 5, the pair of sleeve holding rolls 12 is held together with the lifting frame 20 by the cylinder 21 in a state where the rotation of the pair of sleeve holding rolls 12 is not locked by the locking means (a state where free rotation is possible) The roll 12 is lowered. As shown in FIG. 6, the pair of sleeve holding rolls 12 descends to the lower side of the hanger 10 along both side surfaces of the belt sleeve 100 suspended from the hanger 10a.

  As indicated by a two-dot chain line in FIG. 6, the belt sleeve 100 has a shape in which both side portions thereof bulge outward when the belt sleeve 100 is only suspended from the hanger 10. Here, the separation distance between the pair of sleeve holding rolls 12 is slightly larger than the outer diameter of the hanger 10 (see FIG. 2). Therefore, when the pair of sleeve holding rolls 12 are lowered to the lower side of the hanger 10, the pair of sleeve holding rolls 12 are pressed against both side surfaces of the belt sleeve 100. At this time, the belt sleeve 100 is tightened and deformed from both sides, but at the same time, a repulsive force is generated in the belt sleeve 100 to spread to the original shape. Therefore, the belt sleeve 100 and the sleeve holding roll 12 are brought into pressure contact with each other, and the belt sleeve 100 is securely clamped by the pair of sleeve holding rolls 12. Further, since both side portions of the belt sleeve 100 are held down by the pair of sleeve holding rolls 12, the shape of the sleeve 100 is stabilized at the shape shown by the solid line in FIG.

  Further, as shown in FIG. 2, since the surface of the pair of sleeve holding rolls 12 is covered with the vulcanized rubber 25, the friction acting between the sleeve holding roll 12 and the side surface of the belt sleeve 100 is increased. The clamping force of the roll 12 becomes stronger. Thereby, when the belt sleeve 100 is removed from the hanger 10, it is possible to prevent the belt sleeve 100 from falling.

  In this way, the cylinder 21 (elevating means) simply lowers the pair of rolls 12 from the upper side of the belt sleeve 100 suspended from the hanger 10 to the lower side of the hanger 10 while keeping the horizontal posture. The pair of rolls 12 can be pressed against both side surfaces of the belt sleeve 100. The pair of sleeve holding rolls 12 are arranged so as to sandwich the belt sleeve 100, and the pair of sleeve holding rolls 12 are brought close to each other (changing the separation distance) to sandwich the belt sleeve 100. However, as compared with such a case, in the present embodiment, a cylinder, a guide, and the like for bringing the pair of rolls 12 into and out of contact with each other are not necessary, and the apparatus configuration is simplified.

  In addition, since the pair of sleeve holding rolls 12 is configured to be rotatable, the pair of rolls 12 can be smoothly rotated to the lower side of the hanger 10 while rotating while the pair of rolls 12 are in contact with both side surfaces of the belt sleeve 100. Can be lowered. After the pair of sleeve holding rolls 12 are lowered to the lower side of the hanger 10, the pair of sleeve holding rolls 12 are locked so as not to rotate by the locking means (pin 27 in FIG. 2). Thereby, it is possible to prevent the belt sleeve 100 from falling when the belt sleeve 100 is removed from the hanger 10.

  Next, as shown in FIG. 7, the pair of sleeve holding rolls 12 are moved slightly upward by the cylinder 21 to separate the belt sleeve 100 held by the pair of sleeve holding rolls 12 from the hanger 10, The cylinder 17 moves the pair of sleeve holding rolls 12 forward (in the cylinder axis direction of the opened belt sleeve 100). As a result, the belt sleeve 100 in an opened state held by the pair of sleeve holding rolls 12 is conveyed to the processing device 4 and mounted on the two shafts 5 and 6 of the processing device 4.

  After the belt sleeve 100 is mounted on the two shafts 5 and 6 of the processing apparatus 4, as shown in FIG. 8, the pair of sleeve holding rolls 12 are moved upward from the belt sleeve 100 by the cylinder 21. Release the clamping state. At this time, if the lock of the roll 12 by the lock means (the pin 27 in FIG. 2) is released, the upward movement of the roll 12 becomes smooth. Further, the pair of sleeve holding rolls 12 are retracted by the cylinder 17 to return to the standby state before conveyance.

  In the belt sleeve conveying apparatus 1 according to the present embodiment described above, the pair of sleeve holding rolls 12 are pressed against both side surfaces of the belt sleeve 100 suspended from the hanger 10 to sandwich the belt sleeve 100. At this time, the belt sleeve 100 and the sleeve holding roll 12 are pressed against each other by the repulsive force that tends to spread to the original shape on the belt sleeve 100, and therefore the belt sleeve 100 is securely clamped by the pair of sleeve holding rolls 12. The Further, since both side portions of the belt sleeve 100 are held down by the pair of sleeve holding rolls 12, the shape of the sleeve 100 being conveyed is stabilized. Therefore, the belt sleeve 100 during transportation is prevented from dropping, and the processing device 4 can be securely attached to the shafts 5 and 6.

  Next, modified embodiments in which various modifications are made to the embodiment will be described. However, components having the same configuration as in the above embodiment are given the same reference numerals and description thereof is omitted as appropriate.

1] Even if a pair of sleeve holding rolls 12 are arranged so as to sandwich the belt sleeve 100 suspended from the hanger 10 and the pair of sleeve holding rolls 12 are brought close to each other, the belt sleeve 100 may be clamped. Good. In this case, as compared with the above-described embodiment, a pair of sleeve holding rolls 12 is reliably provided on both side surfaces of the belt sleeve 100, although a cylinder, a guide, and the like for separating and contacting the pair of sleeve holding rolls 12 are further required. Can be pressed.

2] In the above embodiment, the surface of the roll 12 is covered with vulcanized rubber in order to increase the clamping force of the pair of sleeve holding rolls 12, but other than this, a belt sleeve other than vulcanized rubber is used. The roll 12 is sandwiched by covering the roll 12 with a material (for example, a soft synthetic resin material) capable of increasing the frictional force between the roll 12 and increasing the surface roughness of the roll 12 itself. It is also possible to increase power.

3] When the belt sleeve 100 has a deformed wrinkle as shown in FIG. 9A and has, for example, a left-right asymmetric shape, or as shown in FIG. When the vertical length is short, when the belt sleeve 100 held by the pair of sleeve holding rolls 12 is to be attached to the processing device 4, the belt sleeve 100 is attached to the shafts 5 and 6 (particularly, the processing device 4). , It may interfere with the driven roll 6) and surrounding members, and it may be difficult to mount the shafts 5 and 6.

  Therefore, as shown in FIGS. 10 and 11, the belt sleeve conveyance device 1 includes a shape correcting member 30 having a pair of left and right press plates 30 a and a connecting portion 30 b that connects the ends of the pair of press plates 30 a. May be provided. As shown in FIG. 10, the shape correcting member 30 is moved forward from a position retracted backward with respect to the belt sleeve 100 held by the pair of belt holding rolls 12 by appropriate driving means such as a cylinder (not shown). It is driven and attached to both side surfaces of the belt sleeve 100 from the rear. As a result, the pair of presser plates 30a are pressed against both side surfaces of the belt sleeve 100, and the shape of the belt sleeve 100 can be attached to the shafts 5 and 6 of the processing apparatus 4 as shown in FIG. Since it is corrected to the shape, it can be reliably attached to the shafts 5 and 6.

  As described above, when the pair of presser plates 30a (shape correction member 30) is attached to the belt sleeve 100 from the rear, the belt sleeve 100 (FIG. 9 (a)) having a deformed wrinkle or a belt spread laterally. As shown in FIG. 11, it is preferable that the tip portions of the pair of presser plates 30a spread outward so that the sleeve 100 (FIG. 9B) can be easily attached.

  The pair of presser plates 30a is not necessarily configured to be attached to the belt sleeve 100 from the rear. For example, the pair of presser plates 30a is moved from the outside of the belt sleeve 100 to the side surfaces of the belt sleeve 100 by moving the pair of presser plates 30a toward the both side surfaces of the belt sleeve 100 by a cylinder or the like. The structure which presses may be sufficient.

4] In the above embodiment, when the belt sleeve 100 is thin and flexible, the holding force of the pair of sleeve holding rolls 12 is weakened and the holding ability of the belt sleeve 100 is lowered. In this case, as shown in FIGS. 5 and 7 of the above-described embodiment, when the sleeve holding roll 12 moves in the cylinder axis direction of the belt sleeve 100 toward the shaft 5 (6) of the processing device 4, the holding ability is low. For this reason, the sleeve holding roll 12 relatively moves forward with respect to the belt sleeve 100 even when the belt sleeve 100 slightly touches the shaft 5 (6), and the belt sleeve 100 is moved to the shaft 5 (6) of the processing device 4. May not be able to be installed stably.

  Therefore, in the apparatus shown in FIG. 13, each of the pair of sleeve holding rolls 12 is a processing apparatus 4 for the belt sleeve 100 so that the flexible belt sleeve 100 can be stably attached to the shaft 5 (6). A sleeve pressing member 40 that abuts against an end surface (right end surface) opposite to the shaft 5 is provided. The sleeve pressing member 40 is a cylindrical member whose outer diameter is slightly larger than that of the sleeve holding roll 12. The sleeve pressing member 40 is externally fitted to a base end portion of the sleeve holding roll 12 that is supported by the elevating frame 20 (second elevating frame member 23), and is further secured by a bolt 41 to the sleeve holding roll. 12 is fixed. The left end surface of the sleeve pressing member 40 is in contact with the right end surface of the belt sleeve 100 that is sandwiched between the sleeve holding rolls 12.

  According to this configuration, when the shaft 5 is mounted, the pair of sleeve holding rolls 12 moves toward the shaft 5 of the processing device 4 in the cylinder axis direction of the belt sleeve 100 (the direction of the arrow in FIG. 13). Sometimes, since the holding ability of the sleeve holding roll 12 is low, the right end surface of the belt sleeve 100 is moved by the sleeve pressing member 40 even when the sleeve holding roll 12 tries to move forward with respect to the belt sleeve 100. Since the pressure is pressed, the sleeve holding roll 12 and the belt sleeve 100 move integrally toward the shaft 5. Therefore, the belt sleeve 100 can be stably attached to the shaft 5.

  The cylindrical sleeve pressing member 40 shown in FIG. 13 is merely an example, and the sleeve pressing portion of the present invention is not limited to this. For example, a plate-like sleeve pressing member may be provided on the sleeve holding roll. The sleeve pressing member may be provided individually for each of the pair of sleeve holding rolls 12 or may be provided so as to straddle the base end portions of the pair of sleeve holding rolls 12 in common. Furthermore, the sleeve pressing portion does not have to be formed of a member different from the sleeve holding roll, and may be, for example, a hook-shaped sleeve pressing portion integrally formed with the sleeve holding roll.
