In order to transfer the workpiece a to the carry-out conveyor 2, the relay conveyor 3 is driven in the receiving direction A to receive the workpiece a, and then the relay conveyor 3 is raised to avoid interference between the carry-in conveyor 1 and the carry-out conveyor 2, and the relay conveyor 3 is Then, the relay conveyor 3 is driven to the delivery direction opening, and the workpiece a is delivered to the carry-out conveyor 2.

[Problems to be Solved by the Invention] However, in the configuration in which the relay conveyor 3 is raised and lowered in this manner, there is a problem in that it is difficult to increase the delivery speed of the workpieces. Therefore, it is conceivable to make the relay conveyor circular so that it will not interfere with the incoming conveyor and the unloading conveyor, but if the relay conveyor is made circular in this way, 1
A problem arises in that it becomes difficult to accurately receive the workpiece from the shell conveyor and transfer the workpiece to the carry-out conveyor.

The present invention was made in view of such problems,
The purpose of this is to provide a conveying device that can perform these operations quickly, since it is difficult to receive and deliver workpieces in a good manner.

[Means for solving problem a 1 The conveying device of the present invention includes an incoming conveyor 1 and an outgoing conveyor 2.
A relay conveyor 3 is provided at this intersection to receive the work from the carry-in conveyor 1 and carry it out to the carry-out conveyor 2. A receiving and delivering conveyor 5 is provided to protrude and retract from the leading edge of the receiving and delivering conveyor 5, and the driving direction of the receiving and delivering conveyor 5 can be freely switched to the receiving and delivering direction.

[Function 1] In this way, the receiving and delivering conveyor 5 is provided on the relay conveyor 3 so as to be able to protrude and retract from the leading edge of the relay conveyor 3, and the driving direction of the receiving and delivering conveyor 5 can be freely switched to the receiving and delivering direction. By configuring the receiving and passing conveyor 5
The workpiece a is successfully received from the carry-in conveyor 1 by the protrusion, and the receiving and delivery conveyor 5 is retired to horizontally rotate the relay conveyor 3. Next, the receiving and delivery conveyor 5 is made to protrude and the workpiece a is transferred to the carry-out conveyor 2. In this way, it is not possible to receive and deliver the workpiece a well on the receiving and delivering conveyor 5, so the receiving and delivering conveyor 5 is retired and the relay conveyor 3 is rotated horizontally, and the relay Avoiding the vertical movement of the conveyor 3, the workpiece a can be quickly and well handled without giving any vertical vibration to the workpiece a.
The relay conveyance ends at .

【Example] Embodiments of the present invention will be described in detail below based on the drawings.

The carry-in conveyor 1 and the carry-out conveyor 2 are arranged to be substantially orthogonal to each other when viewed from above. Carrying in conveyor 1 at this intersection
A relay conveyor 3 is provided for receiving, for example, a flat plate-shaped workpiece a from the conveyor belt and carrying it out to a carrying-out conveyor 2. The relay conveyor 3 is configured to freely rotate only horizontally around a vertical axis 4. A receiving and delivering conveyor 5 is provided so as to be able to protrude and retire from the leading edge of the relay conveyor 3. The receiving and delivering conveyor 5 is constructed so that its driving direction can be freely switched between the receiving direction and the delivery direction. As such a receiving and delivering conveyor 5, a well-known one called a switch pack type conveyor is used. For example, as shown in FIG. 9 is supported by a bearing 10, a driving wheel 11 and a driven wheel 12 are attached to these, and the receiving and delivery conveyor 5 is rotated in the forward and reverse directions by the forward and reverse driving rotation of the motor 13, and the board 6 is rotated by the sill-7. By pushing and pulling, the receiving and delivery conveyor 5 is transferred to the relay conveyor 3. Although the switchback type conveyor is designed to protrude from the conveyor or to be retracted from the conveyor, the configuration of such a switchback type conveyor can be modified in various ways. A fixed conveyor 14 is disposed on the side of the receiving and delivering conveyor 5, and the driving direction of the conveyor 14 can also be switched between the receiving direction (a) and the delivery direction (a) for the workpiece (a).

The conveyor 14 and the receiving and transferring conveyor 5 are provided at the interway level.

In this way, the receiving and delivering conveyor 5 is provided on the relay conveyor 3 so as to be able to protrude and retire from the leading edge of the relay conveyor 3, and the receiving and delivering conveyor 5 is configured to be able to freely switch its driving direction to the receiving and delivering direction. Then, the receiving and transferring conveyor 5 protrudes to successfully receive the workpiece a from the carrying-in conveyor 1, and then the receiving and transferring conveyor 5 is retired, the relay conveyor 3 is horizontally rotated together with the vertical axis 4, and then the receiving and transferring conveyor 5 is rotated horizontally. 5 is protruded and the conveyor 2 is discharged.
Work a is delivered to. After receiving and delivering the workpiece a well on the receiving and delivering conveyor 5 in this way, the receiving and delivering conveyor 5 is retired and the relay conveyor 3 is horizontally rotated to avoid vertical movement of the relay conveyor 3. The workpiece a can be quickly and well removed without giving any vertical vibration to the workpiece a.
The relay transportation is carried out. That is, the relay of workpiece a uses a sensor (
(not shown), the receiving and delivery conveyor 5 is driven in the receiving direction and is made to protrude from the relay conveyor 3, and the sensor 15 detects that the workpiece a has been received on the receiving and delivery conveyor 5. Based on the result, the receiving and delivering conveyor 5 is retired, this retreating position is detected by the sensor 16, and based on this detection result, the backward drive is stopped, and the driving of the receiving and delivering conveyor 5 is also stopped, and then the relay conveyor is 3 to drive and rotate the vertical pongee 4 to rotate the relay conveyor 3 approximately 90
° The receiving and delivering conveyor 5 is reversed to face the delivery conveyor 2, and the receiving and delivery conveyor 5 is driven to the delivery direction opening and projected from the relay conveyor 3, and the workpiece a is delivered to the delivery conveyor 2. be. And once the delivery is complete,
The receiving and transferring conveyor 5 is retired, its drive is stopped, and the rotation of the vertical shaft 4 returns the relay conveyor 3 to its original receiving position.

[Effects of the Invention 1] In short, the present invention provides a carry-in conveyor and a tatami conveyor so as to intersect with each other, and a relay conveyor is provided at this intersection to receive the work from the carry-in conveyor and carry it out to the carry-out conveyor. A receiving and delivering conveyor is provided that protrudes from the leading edge of the conveyor and can be freely retracted.
Since this receiving and delivering conveyor is constructed so that its driving direction can be freely switched to the receiving and delivering direction, the workpieces can be received from the carry-in conveyor by the projection of the receiving and delivering conveyor, and the receiving and delivering conveyor is The relay conveyor is horizontally rotated by being retired, and then the receiving and delivering conveyor is protruded and the workpiece can be transferred to the carrying out conveyor. In this way, the receiving and passing conveyor can smoothly receive and deliver the workpiece. Since the receiving and delivery conveyors are retired and the relay conveyor is rotated horizontally, the vertical movement of the relay conveyor can be avoided, and the workpieces can be quickly and efficiently removed without vertical vibration.
