Abstract

PURPOSE:To automatically feed a conveyed object fed to the shifting position by a feeding conveyor to a conveying conveyor provided in the direction perpendicular to the feeding conveyor. CONSTITUTION:A roller conveyor 3 conveying a conveyed object in the same direction as the conveying direction of a conveying conveyor 5 is provided at a position lower than a feeding conveyor 2 in the shifting position where the feeding conveyor 2 and the conveying conveyor 5 cross at a right angle. A chain conveyor is arranged between rotating rollers 6 of the roller conveyor 3. The chain conveyor is lifted and rotated to the position lower than the feeding conveyor 2 before the conveyed object is received in response to the detecting action of a sensor 17, the rotation is stopped while it is lowered at the position lower in height than the upper face of the roller conveyor 3 after the conveyed object is received, and it is again lifted and rotated to the position higher than the roller conveyor 3 after the conveyed object is conveyed to the conveying conveyor 5 by the roller conveyor 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for changing the direction of conveyance of a conveyed object by automatically changing the direction of the conveyed object in a direction orthogonal to the direction of the object.

[0002]

2. Description of the Related Art Conventionally, many conveying direction changing devices for converting a conveyed object sent out by a sending conveyor into a direction perpendicular to the sending conveyor have been developed and known before the present application, and as an example thereof. The transfer direction changing device for transferring the transferred goods is to receive the transferred goods sent by the sending conveyor, and to transfer the transferred goods received on the receiving conveyor by manually lowering the transferred conveyor to transfer the transferred goods. The transport carriage is manually transported to a predetermined location, and then the transport carriage is manually set again to the original position, and the receiving conveyor is also raised to the position at the start, It was prepared for the transportation work.

[0003]

By the way, in the conventional conveying direction changing device of this kind, since not only the raising operation of the receiving conveyor but also the moving and restoring operations of the conveying carriage are performed manually, During the direction changing work, there is a problem that a worker is always required and labor saving is not possible, and the changing work cannot be efficiently achieved.

According to the present invention, after receiving a conveyed product sent out to a conversion position by a sending-out conveyor, all sensors for raising / lowering operation, rotation, and stopping operation of a chain conveyor for transferring to a roller conveyor and carrying it toward the carrying conveyor are detected. It is an object of the present invention to provide a conveying direction changing device for a conveyed object that can be automatically and continuously performed according to the detection operation of the conveyed object, and thus can perform the conveying direction changing operation of the conveyed object quickly and accurately even when unattended. It was done.

[0005]

In order to achieve the above-mentioned object, in the apparatus for changing the conveying direction of the conveyed article according to the present invention, the constitution is such that the conveying conveyor is arranged at a conversion position where the conveying conveyor and the conveying conveyor are orthogonal to each other. A roller conveyor that conveys the conveyed object in the same direction as the conveying direction is provided at a position lower than the sending conveyor, and the roller conveyor between the rotating rolls of the roller conveyor before receiving the conveyed object according to the detection operation of the sensor. The height of the roller conveyor is higher than the height of the roller conveyor and lower than that of the feeding conveyor to rotate, and after receiving, the rotation is stopped while descending to the position lower than the height of the roller conveyor, and the rollers convey it. After the object is conveyed to the conveyor, it rises again to a position higher than the height of the upper surface of the roller conveyor. A chain conveyor for rotating, in which is disposed for rotation toward the same direction as the transporting direction of the feed conveyor.

[0006]

[Function] When the conveyed product is sent out to the rotating chain conveyor at a position lower than the height of the sending conveyor and higher than the upper surface of the roller conveyor, the transferred product is transferred from the sending conveyor to the rotating chain conveyor, It is sent in the same direction as the sending direction of the sending conveyor.

Therefore, when it is confirmed that the conveyed product has completely transferred from the sending conveyor to the chain conveyor and has been sent to the predetermined position, the rotation of the chain conveyor and the sending conveyor is stopped, and at the same time, the chain conveyor moves downward. Starting, the chain conveyor is lowered to a position lower than the height position of the upper surface of the roller conveyor, and the conveyed product on the chain conveyor is transferred to the roller conveyor.

Therefore, when it is confirmed that the chain conveyor has been lowered to a predetermined position, the lowering operation of the chain conveyor is stopped, and at the same time, the roller conveyor starts rotating, and the conveyed product on the roller conveyor is sent out. Send it out to the conveyor at a right angle.

When it is confirmed that the conveyed product sent out by the roller conveyer has been sent to a certain position outside the chain conveyer, the rotation of the roller conveyer is stopped and the chain conveyer starts the ascending operation. At the same time as it is raised to the height position, the chain conveyor and the delivery conveyor are rotated to prepare for the delivery of the next conveyed product.
