Abstract

PURPOSE:To provide an automatic flapping method for a panel transfer device to carry panel components to a plurality of transfer sections after delivery from a transfer press. CONSTITUTION:Regarding an automatic flapping method where a panel W fed from an inspection conveyor 12 is vertically flapped with a vertical flapper conveyor 13, and received with a transverse flapper conveyor 26 for changing a transfer route for discharge, the discharge end of the conveyor 12 is fitted with the first sensor 50. On the other hand, the discharge end of a vertical flapper conveyor 51 is fitted with the second sensor 51. In this case, the first sensor 50 detects the panel W, thereby causing the oscillation of the conveyor 13. At the same time, the second sensor 51 detects the panel W, thereby stopping the receiving operation of the conveyor 26 and starting the discharge operation thereof.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically allocating a panel transfer device for transferring panel parts transferred from a transfer press to a plurality of transfer parts.

[0002]

2. Description of the Related Art Conventionally, as a device for automatically loading panel parts sent from a transfer press into a container or the like, an automatic loading device such as that disclosed in Japanese Patent Laid-Open No. 62-83970 is known. The workpieces continuously sent from the intermittent feeding device are distributed to a plurality of transfer devices and conveyed, and are automatically loaded into the container.

[0003]

However, in such a conventional apparatus, since it is necessary to process the continuously fed works without stagnating, a transfer section composed of a plurality of transfer apparatuses and a plurality of containers is installed. There is a problem that space is likely to be wasted because the workpieces are distributed and arranged in a wide range in a plane and it is necessary to secure a work carrying path leading to each transfer section. Therefore, the space is used three-dimensionally to reduce the planar space, and the work to be carried out to the plurality of transfer parts is sorted and arranged, and the process is automated to save labor. There was a need.

[0004]

In order to solve the above problems, the present invention distributes panels sent from a carry-out conveyor up and down by a swinging conveyor, and receives the distributed panels by upper and lower multi-stage conveyors, In the automatic distribution method in which the carrying direction is changed and paid out, a first sensor is provided downstream of the carrying conveyor and a second sensor is provided downstream of the swing conveyor, and the first sensor is a panel. Is detected, the swinging conveyor is swung up or down, and when the second sensor detects the panel, the receiving operation of the corrugated conveyor is stopped and the dispensing operation is started.

[0005]

The first sensor detects the panel and causes the rocking sensor to rock, so
The panels are sent alternately up and down. Further, when the second sensor detects the passage of the panel, the receiving operation of the corrugated conveyor is stopped and the payout operation is started, so that the panels can be automatically distributed. And such a combination enables space saving and labor saving.
