DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer press delivery apparatus for transferring a work carried out of a transfer press to a rack position for loading the work on the rack.

[0002]

2. Description of the Related Art A line incorporating a transfer press for performing a forming process such as drawing, edging, drilling, etc. on a work by one press machine is shown in FIG.
When the work 1 is carried into the first station of the transfer press 3 by the entry-side device 2, the forming is advanced for each station while being sequentially transferred by the work transfer device. , Running,
It is conveyed onto the output conveyor 4 which is an index conveyor that repeats stopping and is conveyed to the position of the manual rack device 5, and while the output conveyor 4 is stopped, a pair of workers puts on the output conveyor 4. It is configured to be picked up more and sequentially loaded on the manual rack device 5.

In the above transfer press line,
For example, when a panel material such as an automobile part is handled as the work 1, if the panel material is damaged, the damage may appear even when the panel material is painted. Since it is attached, it is necessary to handle it carefully. For this reason, a manual racking system called a so-called MRS is often used as shown in FIG.

[0004]

However, the speed of recent large-size transfer presses has been increased (for example, 20 strokes / minute), while the work 1 to be formed has also been increased in size (for example, 2 m × 2 m, 10 m 2). １５15 kg), it takes a lot of work for the worker to pick up and load the work 1 at the same time during the short stop time of the outlet conveyor 4, and there is a problem that a large amount of labor is required. Operation has to be interrupted or decelerated.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a transfer press delivery apparatus capable of coping with high-speed production even when a manual racking system is employed.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention distributes the work transferred from the delivery conveyor up and down to a downstream position of the delivery conveyor of the transfer press. Provide a flap conveyor for, in the upper part of the downstream position of the flap conveyor, arrange the upper intermediate conveyor, in front of the upper intermediate conveyor, installed a central payoff table via a transport device,
In addition, a lower intermediate conveyor having a shorter length than the upper intermediate conveyor is arranged at a lower portion of the downstream position of the flap conveyor, and a horizontal feed base extending in the left-right direction is provided at a downstream position of the lower intermediate conveyor. A shuttle conveyor for feeding the work received from the lower intermediate conveyor in the left-right direction on the traversing platform, and further, transporting the workpiece in front of one or both of the left and right sides of the traversing platform. Another payoff table is provided via the device.

[0007] When the work is delivered from the output conveyor to the flap conveyor, the work is sent out to the upper intermediate conveyor or the lower intermediate conveyor by the sorting operation of the flap conveyor, and the work on the upper intermediate conveyor is The work is sent out to the central payoff table, and the work on the lower intermediate conveyor is fed out to the left or right payoff table after being traversed by the shuttle conveyor. Therefore, high-speed production can be handled by allocating the work feeding direction to the flap conveyor in accordance with the molding speed of the transfer press.

When two shuttle conveyors, one for the left side and the other for the right side, are provided on the traversing platform, the frequency of panel arrival per payoff table is reduced, and the load of loading workers is reduced. Can be performed without difficulty, and it is possible to cope with a further increase in speed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 (a) and 1 (b) show an embodiment of the present invention, and show a downstream position (front side) of a delivery conveyor 4 for transporting a work 1 formed by a transfer press 3 downstream. Position), a flap conveyor 6 for vertically distributing and conveying the work 1 transferred from the delivery conveyor 4 in a vertical direction is provided at a position downstream of the flap conveyor 6 in the conveyance direction. The upper intermediate conveyor 7 having a long length is arranged at the upper part (front side position), and the lower part which is about half the length of the upper intermediate conveyor 7 is arranged at the lower part at the downstream position of the flap conveyor 6 in the transport direction. The intermediate conveyor 8 is arranged, and the work 1 on the flap conveyor 6 can be distributed to the upper intermediate conveyor 7 and the lower intermediate conveyor 8 and sent out by the vertical displacement of the flap conveyor 6. To.

Further, a central payoff table 10a is installed via a transfer chute 9a in front of the upper intermediate conveyor 7 in the transport direction, and the work 1 on the upper intermediate conveyor 7 is
