[Problems to be solved by the invention]

However, in such a conventional device for separating and separating arc-shaped members, the lining 51, which is an arc-shaped member, is conveyed to a conveyor 5 having different conveying speeds v ₁ and v _2.
Since the structure is changed to 0, 52 for separation, a substantial alignment effect cannot be obtained, and the lining 51 needs to be mounted on one of the conveyors 50 in an aligned state, and the inclination tends to fluctuate during transfer. It has been difficult to provide uniform spacing and attitude separation.

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional technical problem, and has a structure including a plurality of conveyors arranged in parallel with a predetermined gap therebetween, and the conveyor. Above, an arc-shaped member to be mounted in a position that is concave forward or backward in the feed direction, and disposed in the gap,
A stopper member protruding from the upper surface of the conveyor to lock the arc member, a pusher disposed in the gap around the stopper member, and a circumferential direction of one arc member directly locking to the stopper member And a push-up / down drive device for pushing up a central portion of the stopper member so as to release the engagement with the stopper member. Then, the pusher can be constituted by a tubular member that fits loosely on the outer periphery of the stopper member. Furthermore,
A plurality of stopper members can be arranged in a direction orthogonal to the direction of feed of the conveyor.

[Action]

A plurality of arc-shaped members placed on the base end of the conveyor in a forward or backward concave position and conveyed in a fixed direction are conveyed to an intermediate portion of the conveyor, and then successively engaged with the stopper member. Stop and align. This alignment state can be obtained almost independently of the diameter of the arc-shaped member if the arc-shaped member has a size to be transported on the belts on both sides.

[0006] From this state, the operation of separating the arc-shaped members is started. When the pusher is driven up by the lifting drive device, the central portion in the circumferential direction of one arc-shaped member that is directly engaged with the stopper member is pushed up, and the engagement with the stopper member is released. One arc-shaped member whose central part is pushed up, since both ends in the circumferential direction are in contact with the conveyors on both sides, so that it moves in the feed direction and is disengaged from the stopper member and the pusher, and is placed on the conveyor. Fall. If the upper surface of the pusher is formed so as to be gradually inclined downward in the feed direction, the arc-shaped member slides down the upper surface of the pusher quickly and reliably. When the pusher is driven downward by the lifting drive, the next arc-shaped member is locked to the stopper member.

[0007] In this way, the arc-shaped members can be separated one after another after being aligned and conveyed to the next step. In addition, if the pusher is formed of a cylindrical member that is loosely fitted on the outer periphery of the stopper member, the pusher and the stopper member can be compactly arranged in a gap between the plurality of conveyors, and the stopper member can be formed into a circular arc-shaped stopper member. Can be reliably released. Further, if a plurality of stopper members are provided, the arc members are locked to the stopper members at a plurality of positions in the direction orthogonal to the feed direction, so that the aligned state of the arc members can be stably obtained in a stable state.

Next, the operation of the above embodiment will be described. The plurality of linings 6 placed on the base ends of the conveyors 2, 3, and 26 in a forward concave posture and conveyed in the feed direction A are conveyed to intermediate portions of the belts 2a, 3a, and 26a. 4, as shown in FIG. 5, the stopper members 4 and 5 are sequentially locked and aligned. Since the pair of stopper members 4 and 5 are provided, the alignment state of the lining 6 that is locked at two points in the direction orthogonal to the feed direction A can be stably obtained in a stable posture. In this alignment state, the lining 6 is the belt 2 on both sides.
If it has a size that can be transported on a and 3a, it can be obtained almost independently of its diameter.

From this state, the separation work of the lining 6 is started. If the piston rod 9a of the cylinder device 9 is protruded and the pushers 7, 8 are integrally driven up via the support plate 9b, the intermediate portion of one lining 6, which is directly engaged with the stopper members 4, 5, is pushed up. Then, the engagement with the stopper members 4 and 5 is released. Since the one lining 6 whose intermediate portion is pushed up has both ends in the circumferential direction in close contact with the belts 2a and 3a on both sides, the lining 6 moves in the feed direction A and is disengaged from the pushers 7 and 8. , Fall on the belts 2a, 3a, 26a as shown in FIG. 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 feed direction A, the lining 6 does not lock onto the upper surfaces of the stopper members 4 and 5. , And quickly and reliably slide down on the upper surfaces of both pushers 7 and 8.

When the lining 6 on the belts 2a, 3a, 26a reaches the front end in the feed direction A again and the both ends in the circumferential direction ride on the plate 11f, the transfer device 11 is driven. Transfer to the conveyor 12. That is, if the cylindrical member 11a, the plate-like body 11f, and both culms 11b, 11c are integrally rocked and driven via the belt 11g, the lining 6 whose both ends in the circumferential direction are located on the plate-like body 11f gradually becomes. The user stands on the conveyor 12 in an upwardly convex posture. The lining 6 on the conveyor 12 is in the direction B
To the next step. When the lining 6 has been transferred, the cylindrical member 11a, the plate-like body 11f, and both culms 1
1b and 11c are returned to the original positions located below the upper surfaces of the belts 2a, 3a and 26a. Receiving part 11d,
11e prevents another lining 6 from entering under both culms 11b and 11c during the transfer work of the lining 6.

After the plurality of linings 6 are locked and stopped by the stopper members 4 and 5 in this manner, the pushers 7 and 8 are intermittently operated to separate the linings 6, and the linings 6 are successively processed in the next step. Transport to

In the above embodiment, the stopper members 4, 5 and the pushers 7, 8 are connected to the conveyors 2, 3,
26, two sets are arranged in a direction orthogonal to the feed direction A, and the pushers 7, 8 are driven up and down by one cylinder device 9. However, the stopper member and the pusher are connected to the conveyors 2, 3 on both sides. , And a set substantially identical to that of the above embodiment can be obtained. In this case, the central conveyor 26 is omitted, and the conveyors 2 and 3 on both sides are driven by the driving device.

Although the pushers 7 and 8 are formed of cylindrical members that are loosely fitted to the outer periphery of the stopper members 4 and 5, the pushers 7 and 8 are directly engaged with the stopper members 4 and 5 when the pushers 7 and 8 rise. The central part of one lining 6 may be pushed up so as to be in a semi-erected state, and may have a function of releasing the engagement with the stopper members 4, 5, and may be formed by an arc-shaped member. It is also possible to provide them separately from the members 4 and 5. Further, the lining 6 is moved in the feed direction A
Is placed on the conveyors 2, 3, and 26 in a forwardly concave position, but it can be placed in a backwardly concave position to obtain substantially the same operation.
