And a vacuum suction device 23, and the work sent to the position of the belt 22 with holes facing the first conveyor 1 is sucked by the vacuum suction device 23 through the holes of the belt 22 to the belt surface, and below it. It is descended and fed into the arranged transfer conveyor 3 almost vertically. As shown in FIG. 3, the distance between the edge of the tip of the adjusting plate 13 and the holed belt 22 is such a value that only one work is passed. In the figure, 24 is a tube connecting the vacuum suction device to a vacuum source, and 25 is a motor for driving the belt 22 with holes.

The inlet side of the transfer conveyor 3 is located below the outlet side of the first conveyor 1, and as shown in FIG.

The belts are driven by drive motors 28 and 29 at the same speed and in opposite directions. . Also, the endless belts are guided by a series of guide rollers 30 in the areas where they contact each other. The work is fed into the transfer conveyor 3 one by one by the adjusting plate 13 and the work is separated from each other and carried between the belts 26 and 27 as shown in FIG. .

The sensor-4 senses the work in a state where the works are separated from each other, and inputs the signal to a counter (not shown) to count the work. 3 at a suitable position, preferably on the inlet side of the transfer conveyor 3 as shown in FIG. As the sensor-4, an optoelectronic switch including a light emitting device 31 and a light receiving device 32 is used in the illustrated example, but it goes without saying that another type of detection switch may be used.

Therefore, in this transfer apparatus, a work which descends in a vertical (vertical) state is received, and the work rises vertically and is sent to the second conveyor, but the transfer conveyor 3 is moved upward. Alternatively, the arrangement may accept a vertically ascending work and a vertically descending work to deliver the work.
Since this transfer device is composed of the feeding conveyor 2 and the transfer conveyor 3, the mechanism is simplified and the speed is further increased.

As shown in FIG. 4, one end of the second conveyor 5 is arranged at the delivery end of the transfer conveyor 3 and a pusher 6 is provided at that position, and the pusher 6 is provided in the second conveyor 5. The work on the second conveyor is provided opposite to the one end and slightly above the one end, and the work on the second conveyor is provided with a pressing portion 33.
It can be pressed with. The pusher preferably comprises an air cylinder. Also transfer conveyor 3
An endless belt 34 is provided at a suitable distance above the delivery end of the guide to receive and guide the abutment of the upper edge of the delivered work, the belt 34 being driven at a suitable speed.

In this embodiment, the second conveyor 5 is constructed as a belt conveyor, which is located near the delivery end of the transfer conveyor 3 and which hangs the belt 35 of the second conveyor and the transfer conveyor 36. A guide plate 38 for supporting a work is provided between the roller 37 on the delivery end side on which the belt 26 is hung, and the work delivered from the transfer conveyor 3 is rolled as shown in FIG. A state in which it is guided between the belt 26 on the la 37 and the endless belt 34 on it and extruded in the direction of the second conveyor 5, and passes through the guide plate 38 and stands on the second conveyor 5. To move. In the figure, 39 is a holding plate for preventing the work from coming out.

Partitioning members 40 for partitioning are sequentially placed on the second conveyor 5 at appropriate intervals. In the illustrated example, each partition member 40 is configured as a block. Therefore, the work sent to the second conveyor 5 is stacked in a state of abutting the side surface of the partition material, that is, the surface facing the delivery end of the transfer conveyor, and standing on the partition material side. As shown in FIG. 5, the partition material on the second conveyor also moves together with the belt 35 of the second conveyor, and the number of works stacked on the partition material side increases with the movement.

As shown in FIG. 8, this partition member 40 has a second
On the conveyor 5 between the pair of partition materials, it holds the work divided by the planned quantity and holds the work, and the work of the planned quantity between the partition materials is determined by another predetermined quantity. Once moved to the position, it is transported near the receiving side of the second conveyor 5 for subsequent use. Therefore, it is preferable to provide a third conveyor 7 composed of a belt conveyor or the like near the second conveyor, and a partition material 40 on the third conveyor is sequentially moved to the second conveyor. A carrier device 8 is provided. In this example, the third conveyor 7
However, a pusher or the like may be used instead.

The partition member 40 on the second conveyor 5 is transferred to the third conveyor 7 by an appropriate device or manually after a predetermined number of works between the partition members have been moved to another position to play a role. Be moved. Therefore, the third conveyor 7 is the second conveyor 5
It is preferably arranged in parallel with. The partition members 40 are preferably made to have the same weight and the same shape. If the partitioning material is composed of blocks, it has a certain weight, so that a pusher pushes a predetermined number of works on the second conveyor.
Although it has the advantage that it does not move with respect to the surface of the belt 35 when pushed by 6, the partition member 40 may move relative to the surface of the belt 35. The shape of the partition material may be arbitrary as long as it can receive the surface of the work. The partition member 40 does not necessarily have to be a block, and may have any material and shape as long as it is placed on the second conveyor and can serve as a partition.

In order to facilitate moving the partition 40 on the third conveyor 5 to the receiving side of the second conveyor 5, each partition is at least partially made of magnetic material such as iron. In that case, as shown in FIGS. 6 and 7, the partition material conveying device 8 is provided with an electromagnet 41 for appropriately adsorbing the partition material. Although various mechanisms or a suitable robot can be used as the transfer device 8, in this embodiment, in order to simplify the mechanism, a pair of air cylinders 42 and 43 are used, and the movement of the air cylinder 42 in which the mobile shaft operates up and down. An electromagnet 41 is installed at the lower end of the mobile shaft, and the other air cylinder 43 moves the electromagnet 41 laterally together with the air cylinder 42. The partition material 40
May be moved by other methods such as vacuum suction or gripping with a pair of arms.

In the illustrated example, the third conveyor 7 is provided at a position slightly higher than the second conveyor 5,
The relative position may be arbitrary. As shown in FIGS. 6 and 7, a predetermined number of works are sent to the partition member 40 side on the second conveyor, and the pusher 6 is activated to operate the partition member 40.
When the predetermined number of work is pressed between the pusher 33 and the pusher 33 of the pusher, the next partition 40 is placed on the receiving side of the second conveyor 5, so that the pusher 33 pushes the next partition 40. To retreat through. Therefore, as shown in FIG. 7, therefore, the front and rear facing surfaces of the partition member 40, that is, the second conveyor 5
The pair of surfaces perpendicular to the longitudinal direction of the is open so that the pressing portion 33 can pass therethrough.

The operation will now be described. The work placed upright on the first conveyor 1 is the infeed conveyor 2.
Is gradually fed to the transfer conveyor 3, and when it reaches the position of the transfer conveyor 2, the transfer conveyor 3 is separated from the next work one by one.
Is detected by the sensor-4 at the appropriate position, counted, and sent to the exit side. From this transfer conveyor, the work is sent in a vertical state, and is sent to the second conveyor 5 as it is.

A partition member 40 is previously placed on the receiving side of the second conveyor 5, that is, at or near the receiving portion, and the work A is sequentially delivered to the surface of the partition member. You can lean against it. When a predetermined number of works are detected and counted by the sensor-4, the feeding conveyor 2 is stopped, and when the predetermined number of works is sent to the second conveyer, the pusher 6 is operated to finish. By pushing the back surface of the work of the section, a predetermined number of the work is pinched between the partition member 40 and the pressing portion 33 of the pusher, and in that state, the next partition member 40 is placed on the receiving side of the second conveyor 5. Put on.

The transfer of the partition material 40 is carried out by the operation of the partition material conveying device 8, and the electromagnet 4 is moved by the air cylinder 42.
1 is lowered onto the partition material 40 on the third conveyor 7 and raised while supporting the partition material, moved by the other air cylinder 43 onto the second conveyor, and then lowered and placed. . When the next partition is placed on the second conveyor, the pusher 33 of the pusher retracts through the next partition and the above operation is restarted. Therefore, as shown in FIG. 8, each predetermined number of works is placed between each pair of partition members.

[0027]

As described above, according to the present invention, the predetermined number of sheets of sheet-like material are placed between the partition members on the second conveyor, so that the second conveyor is provided. By making the conveying surface of the sheet relatively long, it is possible to relatively increase the number of bundles of the sheet-like objects to be placed thereon, and the sheets separated on the second conveyor. This facilitates the work of moving the object to another position and creates a space.
That is, it is not necessary to always perform the work at a constant speed, a certain degree of slowness is allowed, and the sheet-like material divided on the second conveyor can be handled with a margin.

Particularly, if the transfer device between the first conveyor and the second conveyor is composed of a pair of endless belts, the counting of the sheet-like objects is facilitated, and the adjusting plate is provided at the outlet end of the first conveyor. If it is provided in the above, it is ensured that the sheets are fed one by one. If a guide plate and an endless belt for contacting the upper edge of the sheet-like object are provided on the receiving side of the second conveyor, the sheet-like object can be properly delivered in an upright state. Also, the use of a hollow block with open opposing surfaces simplifies the pusher pressing mechanism.
