【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a view showing an embodiment of the present invention. It is composed of a conveyor 4 that continuously supplies the work 1 and a motor-driven belt 2 that intermittently feeds the work 1 to separate and position the work 1. The surfaces of the conveyor 2 are blocks 5 and 6 which come in front of and behind the work 1, respectively. Is provided, and a set of a work stopper 8 for temporarily stopping the continuous supply of the continuously supplied works, a back plate 9, a transition plate 3, and a work detection sensor 10 for detecting the intermittent start of the conveyor 2 are combined. It is a thing.

Here, as the motor 7, it is appropriate to use a pulse motor in the case of high-speed positioning. Further, the belt of the conveyor 2 is preferably a toothed belt when highly accurate positioning is required. Further, it is convenient to use an air cylinder as the stopper 8 because it is fast and easy to control.

In this case, it is necessary to prevent the subsequent work from coming into contact with the blocks 5 and 6 of the conveyor 2. This means depends on the shape of the work.

As for the first means, that is, as shown in FIG. 4, in which the central portion of the front and rear surfaces of the work has a cutout portion, the width of the work cutout portion is narrower than the width of the conveyor 2 at the center position of the belt of the conveyor 2. Blocks 5 and 6 having a width substantially matching the width are attached. The transition plate 3 is formed with a recess 3a so that the blocks 5 and 6 do not come into contact with each other. As shown in FIG. 6, the first work 1a and the next work 1b in the continuously supplied work group are temporarily stopped at the position where the first work 1a is on the conveyor 2 and the next work 1b is the crossing plate 3. The position of the block 5 is set so as to be located above. Then, when the next work 1b and the subsequent work group are stopped, the conveyor 2 is rotated corresponding to the predetermined set distance, and the block 6 is formed in the cutout portion between the first work 1a and the next work 1b. The first work 1a can be pushed out by entering the gap. The heights of the blocks 5 and 6 are appropriately set depending on the curvature of the pulley of the conveyor 2 and the size of the gap generated between the works.

With the second means, that is, as shown in FIG. 5, in which the front and rear surfaces of the work have cutouts on both sides, blocks 5 and 6 are attached to both sides of the belt of the conveyor 2. ing. The transition plate 3 is formed with concave portions 3b on both sides so that the blocks 5 and 6 do not come into contact with each other. As shown in FIG. 6, the position where the first work 1a and the next work 1b of the continuously supplied work are temporarily stopped is as shown in FIG. 6, where the first work 1a is on the conveyor 2 and the next work 1b is the transition plate 3 The stop position of the conveyor 2, that is, the stop position of the block 5 is set so as to be located above. Then, when the next work 1b and the succeeding work group are stopped, the conveyor 2 is rotated corresponding to the predetermined set distance, and the block 6 cuts the first work 1a and the next work 1b. It is configured so that the first work 1a can be pushed out by entering the gap formed in the portion. The heights of the blocks 5 and 6 are appropriately set depending on the bending ratio of the pulley of the conveyor 2 and the size of the gap generated between the works.

With respect to the third means, which does not have a cutout portion on the bottom surface of the work, the blocks 5 and 6 can be provided at positions as shown in FIGS. 4 and 5, for example. In this case, since the block 6 only functions as a retainer when the belt 2 is slipped, it is not necessary to provide it. As shown in FIG. 4, FIG. 5, FIG. 7, and FIG. 7, the crossover plate 3 has its shape set so that the block 5 does not abut.

As shown in FIG. 7, the first work 1a and the next work 1b in the continuously supplied work group are temporarily stopped at the position where the first work 1a is on the conveyor 2 and the next work 1b is The stop position of the conveyor 2, that is, the stop position of the block 5 is set so as to be located on the transition plate 3. Then, when the next work 1b and the following work group are stopped, the conveyor 2 is rotated corresponding to the predetermined set distance, and the belt 2 when the conveyor belt 2 moves and the first work 1a It is configured such that the first work 1a can be separated from the subsequent works and sent out by the frictional force between them. In this case, the heights of the blocks 5 and 6 are set in consideration of the curvature of the pulley of the conveyor 2 and the stop position of the next work.

As with the third means, the first and second workpiece shapes may be conveyed while coming into contact with the preceding block 5 depending on the magnitude of the frictional force acting, but the work of the same shape may be used. In the case of a block, there is always no fixed problem because the blocks 5 and 6 are always located at fixed intervals. Further, the shapes of the blocks 5 and 6 and the transition plate 3 need to be combined as shown in FIGS. 4 and 5 according to the protruding shape of the front and rear surfaces of the work 1.

Next, the operation of the present invention will be described with reference to FIG. FIG. 8 is a view showing the operation relationship between the belt of the conveyor 2, the stopper 8 and the sensor 10. First, as shown in FIG. 9, the first work 1a is stopped together with a succeeding work group by the block 5 on the conveyor 2 where the work is stopped. At this time, as shown in FIG. 10, the sensor 10 is detecting the work. The stopper 8 is actuated after a certain period of time to press the next work 1b to temporarily stop the subsequent work group.

Then, as shown in FIG. 11, the conveyor 2 moves one pitch (interval between the blocks 5) and stops. After that, the stopper 8 is released and the work group is conveyed by the conveyor 4 until the next work 5 comes into contact with the next block 5 together with the next work 1b. The sensor 10 detects the next work 1b again, and the same operation is repeated thereafter, so that the work can be separated and conveyed in units of one piece. The operation of the conveyor 2 and the stopper 8 is sequence-controlled so that they are activated after a set time has elapsed since the sensor 10 was turned on. If the work is a cube of 1 cm square, the intermittently driven conveyor movement time is about 0.2 seconds, and one cycle time is about 0.5 seconds.
