[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional technical problems, and the structure thereof is a plurality of conveyors arranged in parallel with a predetermined gap, and the conveyors in front of the feeding direction. Alternatively, an arc-shaped member to be placed in a backward concave shape, a stopper member that is arranged in the gap and projects from the upper surface of the conveyor to lock the arc-shaped member, and a stopper member that is arranged in the gap around the stopper member. And a pusher elevating / lowering device that pushes up the central portion in the circumferential direction of one arc-shaped member that is directly locked to the stopper member so as to release the lock to the stopper member. It is a device for aligning and separating circular arc-shaped members. Further, the pusher can be constituted by a tubular member that is loosely fitted to the outer periphery of the stopper member. Furthermore, a plurality of stopper members can be arranged in a direction orthogonal to the conveyor feeding direction.

[Action]

A plurality of arc-shaped members, which are placed on the base end of the conveyor in a concave posture facing forward or backward and are conveyed in a certain direction, are conveyed to an intermediate portion of the conveyor, and then are sequentially applied to the stopper member. Stop and line up. This aligned state can be obtained almost regardless of the diameter of the arcuate member as long as the arcuate member has a size to be carried on the belts on both sides.

From this state, the work of separating the arcuate member is started. When the pusher is driven to move upward by the elevating / lowering drive device, the central portion in the circumferential direction of one arc-shaped member that is directly locked to the stopper member is pushed up, and the lock to the stopper member is released. One arcuate member whose center is pushed up has both ends in the circumferential direction in contact with the conveyors on both sides, so it moves in the feeding direction to release the engagement with the stopper member and the pusher. On the bear. If the upper surface of the pusher is formed so as to be gradually inclined downward in the feeding direction, the arcuate member slides down the upper surface of the pusher quickly and reliably. When the pusher is driven downward by the elevating and lowering drive device, the arc member at the next position is locked to the stopper member.

In this way, the arcuate members can be aligned one after another, separated, and conveyed to the next step. If the pusher is configured as a cylindrical member that fits loosely on the outer circumference of the stopper member, the pusher and stopper member can be compactly arranged in the gap between a plurality of conveyors, and at the same time, the stopper member can be an arc member. It is possible to surely release the lock to. Further, if a plurality of stopper members are provided, the arcuate members are locked to the stopper member at a plurality of positions in the direction orthogonal to the feeding direction, so that the aligned state of the arcuate members can be stably obtained with good posture. ..

Embodiments of the present invention will be described below with reference to the drawings. 1 to 7 show an embodiment in which the present invention is applied to a device for aligning and separating a lining for a drum brake. In the figure, reference numeral 1 indicates a base, and various members are arranged on the base 1 supported on a base 40 via a support member 41. Two conveyors 2 and 3 are arranged on the base 1, and are arranged in parallel with a predetermined gap. Reference numerals 19 and 20 denote rotary shafts rotatably supported by brackets 21 and 22 fixed to the base 1, and pulleys 23a, 23b, 24a and 24b are provided on both sides of the rotary shafts 19 and 20 in the axial direction. Is stuck. The belts 2a and 3a of the conveyors 2 and 3 are wound around the pulleys 23a, 23b, 24a and 24b.

A conveyor 26 is provided so as to be located between the two conveyors 2 and 3. The conveyor 26 is configured by winding a narrow belt 26a around pulleys 25a and 25b fixed to the central portions of the rotary shafts 19 and 20, respectively. As shown in FIG. 2, the belt 26a passes through the through hole of the base 1 and is also wound around the tension roller 27 at the lower end, and the intermediate portion of the belt 26a is in strong contact with the drive pulley 29 which is rotationally driven by the motor 28. Driven. Thus, since the rotating shafts 19 and 20 are rotationally driven by the narrow belt 26a, both belts 2a and 3a are also driven. A predetermined gap S is formed between the belt 2a on one side and the belt 26a on the intermediate side, and between the belt 26a on the one side and the belt 3a on the other side, which are arranged in parallel. ..

A pair of stopper members 4 and 5 are arranged so as to be respectively located in the gap S. The stopper members 4, 5 are arranged in a direction orthogonal to the feeding direction A of the conveyors 2, 3, 26, the lower end portions are fixed to the base 1, and the upper ends gradually descending in the feeding direction A. The parts project from the upper surfaces of the belts 2a, 3a, 26a of the conveyors 2, 3, 26 by a predetermined length. The stopper members 4, 5 have a function of locking the lining 6, which is an arc-shaped member, which is placed on the conveyors 2, 3, 26 in a forward concave shape in the feed direction A.

Further, the gap S is provided with a pair of pushers 7 and 8 located around the stopper members 4 and 5, and a cylinder device 9 which is a lifting drive device of the pushers 7 and 8. Specifically, each of the pushers 7 and 8 is formed of a tubular member that is loosely fitted to the outer circumference of each of the stopper members 4 and 5, and is movable relative to each of the stopper members 4 and 5 in the axial direction. Is. The upper surfaces of the pushers 7 and 8 are gradually inclined downward in the feeding direction A.

As shown in FIG. 3, the cylinder device 9 is fixed between the stopper members 4 and 5 and is fixedly mounted on the base 1. The support plate 9b fixed to the piston rod 9a of the cylinder device 9 has pushers 7 and 8, respectively. Is stuck. By the cylinder device 9, both the pushers 7 and 8 can be integrally driven up and down through the support plate 9b, and the upper ends of the pushers 7 and 8 are moved to the respective belts 2a, 3a and 26a by the retracting operation of the piston rod 9a. Of the lining 6 which is directly locked to the stopper members 4 and 5 by the projecting operation of the piston rod 9a, and the locking to the stopper members 4 and 5 is released. Can be pushed up like. For this reason, the thickness of each pusher 7, 8 is set to be equal to or less than the thickness of one lining 6.

Reference numerals 30 a and 30 b are guide members arranged on the upper surfaces of the belts 2 a and 3 a of the conveyors 2 and 3 on both sides, and are fixed to the base 1 via support members (not shown). Both sides of the conveyed lining 6 are guided by the guide members 30a and 30b.

Next, the transfer device 11 for the lining 6 is arranged at the front ends of the conveyors 2, 3 in the feed direction A. The transfer device 11 includes a cylindrical member 11a rotatably arranged in front of each of the conveyors 2, 3, and 26, and a plate-like body 11f fixed to the cylindrical member 11a by extending in the axial direction. The culms 11b and 11c respectively extending from the intermediate portion of the plate-like body 11f into the gap S are provided, and the tip ends of the culms 11b and 11c form an arc shape centered on the cylindrical member 11a and downward. The receiving portions 11d and 11e extending to the right are formed.

In the normal state, the plate-like body 11f and the culms 11b, 11c extend horizontally and are located below the upper surfaces of the belts 2a, 3a, 26a, and the cylindrical member 11a is It is located above the upper surfaces of the belts 2a, 3a, 26a. When the cylindrical member 11a is rotationally driven by the driving device 11h via the belt 11g, the plate-shaped body 11f and both culms 11b and 11c swing together, so that the plate The body 11f and the culms 11b, 11c next project from the upper surfaces of the belts 2a, 3a, 26a.

Further, as shown in FIG. 1, the conveyor 12 is arranged adjacent to the cylindrical member 11a. On the conveyor 12, the lining 6 lifted by the plate-like body 11f of the transfer device 11 and the culms 11b, 11c is placed in a downward concave posture, and is driven by a motor (not shown) to feed the direction A. The sheet is conveyed in the direction B orthogonal to.

Next, the operation of the above embodiment will be described. The plurality of linings 6, which are placed on the base ends of the conveyors 2, 3, and 26 in a forward concave shape and are transported in the feeding direction A, are transported to the intermediate portions of the belts 2a, 3a, and 26a. As shown in FIGS. 4 and 5, the stopper members 4 and 5 are successively locked and aligned. Since the pair of stopper members 4 and 5 are provided, the aligned state of the lining 6 that is locked at two points in the direction orthogonal to the feed direction A can be obtained in a stable posture. This aligned state can be obtained almost regardless of the diameter of the lining 6 as long as the lining 6 has such a size as to be transported by riding on the belts 2a and 3a on both sides.

From this state, the work of separating the lining 6 is started. If the piston rod 9a of the cylinder device 9 is actuated to project and both pushers 7 and 8 are integrally lifted and raised via the support plate 9b, the intermediate portion of one lining 6 that is directly locked to the stopper members 4 and 5 will be It is pushed up, and the engagement with the stopper members 4, 5 is released. Since one end of the lining 6 whose intermediate portion is pushed up is in contact with both belts 2a and 3a on both sides in the circumferential direction, it moves in the feeding direction A and the engagement with both pushers 7 and 8 is released. Then, as shown in FIG. 7, it falls on the belts 2a, 3a, 26a. Since the upper surfaces of the pushers 7 and 8 and the upper surfaces of the stopper members 4 and 5 are formed so as to be gradually inclined downward in the feeding direction A, the lining 6 is locked to the upper surfaces of the stopper members 4 and 5. Instead, the upper surfaces of both pushers 7 and 8 slide down quickly and reliably.

The lining 6 riding on the belts 2 a, 3 a, 26 a again reaches the front end in the feeding direction A, and when the both ends in the circumferential direction get on the plate-shaped body 11 f, the transfer device 11 is driven. It is then transferred to the conveyor 12. That is, if the cylindrical member 11a, the plate-shaped body 11f, and the two culms 11b and 11c are integrally rocked through the belt 11g, the lining 6 having both circumferential ends positioned on the plate-shaped body 11f is formed. Gradually stand up, take an upward convex posture, and get on the conveyor 12. The lining 6 mounted on the conveyor 12 is conveyed in the direction B and moves to the next step. When the lining 6 is replaced, the cylindrical member 11a, the plate-like body 11f, and the two culms 11b, 11c are returned to their original positions located below the upper surfaces of the belts 2a, 3a, 26a. The receiving portions 11d and 11e prevent the other linings 6 from entering below the culms 11b and 11c during the work of transferring the linings 6.

In this way, after the plurality of linings 6 are locked to the stopper members 4 and 5 and aligned, the pushers 7 and 8 are intermittently operated to separate them, and the linings 6 are successively separated. Transfer to the process.

By the way, in the above embodiment, two stopper members 4, 5 and pushers 7, 8 are arranged in a direction orthogonal to the feed direction A of the conveyors 2, 3, 26, and the pushers 7, 8 are arranged. Although it is configured to be lifted and lowered by one cylinder device 9, one set of the stopper member and the pusher is arranged in the central portion in the direction orthogonal to the feed direction A of the conveyors 2 and 3 on both sides, and the above embodiment is used. It is possible to obtain almost the same action as. In that case, the central conveyor 26 is omitted, and the conveyors 2 and 3 on both sides are driven by a driving device.

Further, although the pushers 7 and 8 are formed by the cylindrical members which are loosely fitted to the outer peripheries of the stopper members 4 and 5, the pushers 7 and 8 are directly locked to the stopper members 4 and 5 when they are raised. As long as it has a function of releasing the locking to the stopper members 4 and 5 by pushing up the central portion of one of the linings 6 to bring it into a semi-standing state, it is also possible to form it with an arc-shaped member. It is also possible to provide it apart from the stopper members 4, 5. Furthermore, although the lining 6 is placed on the conveyors 2, 3, 26 in a posture in which it is concave in the forward direction of the feeding direction A, it is possible to obtain a substantially similar effect by placing it in the posture in which it is concave in the rear direction. it can.
