Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feeding device for supplying a press part called a blank material cut to a fixed size or a blank material punched by a blanking press to a press machine. In order to perform bending, drawing, trimming, or a combination of these secondary processes on primary processed parts, such as blanks stacked in a magazine case, the blanks stacked in the magazine case are automatically and sequentially processed. This invention relates to a novel press part supply device that supplies a material supply port of a press machine.

Conventional press machine supply equipment for press parts stacks blanks in one layer, that is, a magazine case containing only one pile of blanks is carried below the material supply port of the press machine, and the blanks are stacked one layer from the top. This process is repeated by feeding blanks to the press machine while sucking them one at a time, and when the magazine case is empty, carrying a new actual magazine filled with blanks into the press machine, but with this conventional method, the number of stacked blanks is relatively small. Press work for thick plates with a small number of presses required frequent replacement of magazine cases, and there was a serious drawback in that a worker had to be stationed at the press machine at all times. This was only possible because the magazine case was designed to only allow one pile of blanks to be loaded.

The present invention aims to improve upon these drawbacks, with the aim of achieving true automation that does not require the deployment of crew members. To explain this using drawings, the first

■Resolve the garrison ability. For the empty magazine case 0, another new real magazine 6 fully filled with blanks (B), which has already been mounted on the real magazine supply rail device (A), is placed on the upper table. When the empty magazine case (G) is sent toward the company, the empty magazine case (G) is pushed out by the real magazine (2), and the empty magazine case (G) is discharged by the pulley (9f) of the extension rail (8f). (CB).

When the actual magazine (d) fed later reaches the predetermined position on the upper table 0, the magazine locking device @
When the real magazine (d) is partially parked at a predetermined position on the table 00, the replacement of the empty magazine case (G) and the real magazine (G) is completed. The subsequent feeding of the blank material to the chin press machine (P) is as described above.

In this way, as long as new real magazines (d) continue to be supplied, the device of the present application is operated repeatedly without rest, but the order in which the various parts of the device work is determined by an automatic control circuit that is controlled by the transmission of electrical signals. The structure is such that the worker only has to press the start signal switch button first.

To give an overview of how this automatic control works, each cylinder can be controlled by a solenoid valve (not shown) by sending an electric signal.
The spool of the electromagnetic valve switches the piston rod of the cylinder to either protrude or retract or maintain its current position. Then, turn on the state where the piston rod of each cylinder protrudes,
If the immersion state is turned off, the flowchart 1 of the control circuit described above will be as follows.

The cylinders that are ON as an initial condition are the intermediate table movement cylinder (8) and the upper table movement cylinder (5f).
It is. When the pusher cylinder (not shown) installed in the real magazine supply rail device A is turned on, the real magazine (G) is sent to the upper table 0, and when the signal of the end point of the pusher cylinder is turned on, the locking cylinder (3k x 3k) is turned on, and the pusher cylinder is turned on. Push-up cylinder (L) when OFF, E
is ON, but it is stopped in the middle and held as it is. When the stroke of the cylinder (not shown) that moves the vacuum cup (2p) up and down exceeds the range, a limit switch is activated to send this signal to the cylinder 0. ) so that it is transmitted to the solenoid valve of the push-L cylinder (
The push-up body (11) of L) protrudes intermittently such as when it is held ON and when it is held ON.

Under these circumstances, the cylinder of the vacuum cup (2p) is repeatedly turned ON and OFF while the press machine (P) is in operation, matching the stroke cycle of the press machine (2). When it reaches the upper position, it turns OFF, and when the push-up body (1g) goes down to the lowest position, the upper table moving cylinder (sf) turns OFF, and the push-up cylinder O,)0\
After repeating , the push-up cylinder (L) is turned off, the intermediate table movement cylinder (S) is turned off, and the push-up cylinder (L) is turned off.
After repeating OM, the push-up cylinder Q,) is turned off, and the upper table is moved! J N9” (5f) OFF, Oshiage'/
After repeating 'J printer (L) ON, 0N7), press L cylinder (I,) OFF, intermediate table movement cylinder (S) 0
When the locking cylinder (3k x 3k) is turned OFF, it returns to the original state, and when the pusher cylinder becomes or'H again, a new actual magazine i is transferred.

The invention of the present application, which has the above-mentioned structural action, is capable of automatically breaking down a pile of blanks one by one without stopping a press machine from an actual magazine in which a plurality of piles of blank materials are formed in a base magazine case. This device not only eliminates the need for press workers, but also reduces the number of magazine cases, so the number of trips to the magazine supply rail device and the frequency of transportation are extremely reduced. Become,
Productivity is dramatically improved because transportation workers are not required to be in charge of multiple press machines at the same time.■
- It has a number of excellent effects such as ease of performance and volume management.
