Abstract

PURPOSE:To greatly reduce the tact time and improve the working efficiency by arranging a reversing part respectively between a carrying-in conveyor and the first carrying-out conveyor and in the second carrying-out conveyor so as to make respective one sides of the first conveyor and the second conveyor coincide with each other by a rotary raising-lowering mechanism of a stand. CONSTITUTION:When a conveyance material 1 is carried to the first conveyor by a carrier conveyor in a condition where the first conveyor 11 coincides with the carrier conveyor, a stand 16 is raised in rotation so as to make the first conveyor coincide with the first carrying-out conveyor while a position of the conveyance material is being determined by a stopper 15. In the first conveyor, when the conveyance material is pushed out in the carrying direction by a pushing-out means 13, delivery of the conveyance material is completed. When the first conveyor is raised in rotation and the first conveyor coincides with the first carrying-out conveyor, the second conveyor 12 coincides with the carrier conveyor, and also coincides with the second carrying-out conveyor installed in the same height with the carrier conveyor.

Description

Detailed Description of the Invention

[0001]

[Industrial applications]

The present invention relates to a sorting and feeding device, and more specifically,
The objects to be conveyed at high speed by the transfer line formed by the transfer conveyor are installed at the same height as the transfer line formed by the transfer conveyor at a position that has a height difference from the installation position of the transfer conveyor. The present invention relates to a sorting / feeding device that sorts and feeds out to and from a carry-out line formed by a carry-out conveyor.

[0003]

[Prior art]

For example, in a manufacturing factory for office desks, etc., a top plate is conveyed along a production line by a roller conveyor,
Processing of each step is performed.

[0005] Conventionally, when a top plate is conveyed, an object conveyed at a high speed by a conveyor line formed by a conveyor is formed by an unloading conveyor at a position having a height difference with respect to the installation position of the conveyor. An unloading line,
Workers mainly perform the work of allocating and delivering the transfer conveyor to a transfer line formed by a transfer conveyor installed at the same height.

[0006]

[Problems to be Solved by the Invention]

However, since the top plate is generally large and heavy, it is not easy for an operator to handle.

Therefore, the work of sorting and delivering the top plate as the transported object by the worker is troublesome, and the sorting process cannot be done in time for the top plate which is transported at a high speed, resulting in a considerable takt time and improving the work efficiency. There was also a limit.

[0009] Therefore, there has been a demand for a means that can carry out the conveyed articles without the need for an operator and can improve the working efficiency.

[0010]

[Means for Solving the Problems]

Means for solving the problems of the present invention are as follows.

Firstly, the reversing portion provided between the transport conveyor and the first carry-out conveyor and the second carry-out conveyor conveys the article carried by the carry conveyor with the first carry-out conveyor and the first carry-out conveyor having a height difference. It is a device that sorts and feeds out to two carry-out conveyors, and the reversing unit arranges a first conveyor and a second conveyor in different carrying directions in two stages, one above the other, and stops the carried goods when carrying into the first conveyor and the second conveyor The first conveyor and the second conveyor are provided with a stopper and an extruding means for pushing out the conveyed product in the carrying-out direction.
The conveyor is attached to a pedestal having a rotary elevating mechanism, and the rotary elevating mechanism causes the first conveyor and the second conveyor to be aligned with the first conveyor and the second conveyor, respectively. It is an apportioning and feeding device characterized by rotating and raising and lowering.

[0013]

[Action]

According to the above apparatus, when the conveyed product is conveyed onto the first conveyor by the conveying conveyor in a state where the first conveyor is aligned with the conveying conveyor, the position of the conveyed product is determined by the stopper, The gantry rotates up to align the first conveyor with the first unloading conveyor.

Then, in the first conveyor, the conveyed article is pushed out in the conveying direction by the pushing means, whereby the delivery of the conveyed article is completed.

When the delivery of the conveyed product by the first conveyor is completed, the gantry rotates and descends to the opposite side, and after the first conveyor returns to the state where it coincides with the conveyed conveyor, the series of operations described above is repeated.

When the first conveyor is rotated up and the first conveyor is aligned with the first unloading conveyor, the second conveyor is aligned with the transfer conveyor and is installed at the same height as the transfer conveyor. Matches the second unloading conveyor.

In this state, when the conveyed product is conveyed onto the second conveyor by the conveying conveyor, the conveyed product is pushed out in the conveying direction by the pushing means while the position of the conveyed product is determined by the stopper. The delivery of goods is completed.

The top plate 1 conveyed onto the second roller conveyor 12 is positioned by the second stopper 27 in a raised state, and then is moved by the second push-out plate 14 in the conveying direction which is the hand-loading side orthogonal to the carrying-in direction. The top plate 1 is pushed out and the top plate 1 is extended.

Here, the top plate 1 is pressed by the proximity switch S6.
If is detected, it means that the second stopper 27 is in a lowered state, and therefore the failure is normally stopped.

While the first roller conveyor 11 is moving up, it is necessary to set the motor roller of the second roller 20 to operate again after the passage of the top plate 1 is sensed by the proximity switch S7. Then, accept the next top plate 1,
The series of operations described above can be repeated.
