Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a panel check device for checking a panel formed by a transfer press in a press body.

[Conventional technology]

The transfer press has a plurality of processing stations, and is configured to transfer a panel to each processing station, carry in a panel, and carry out a panel by a transfer bar operating in two-dimensional or three-dimensional directions.

Further, in the transfer press in which the transfer bar operates in the two-dimensional direction, a plurality of crossbars are laid horizontally between the transfer bars, and a panel holding means such as a vacuum cup for adsorbing the panel to the crossbars is provided. There is.

In the above transfer press, when the press main body is stopped to check the panel being formed, the cross bar d is held with the panel holding means c adsorbing the panel b on the lower mold a as shown in FIG. Is stopped.

[Problems to be solved by the device]

Therefore, when an operator enters the press body and checks the panel, there is a problem that the panel holding means c interferes with the check.

This invention was made with the aim of improving the above-mentioned problems.It provides a panel check device for a transfer press that makes it possible to raise the crossbar to an unobtrusive position when checking the panel, making it easier to check the panel. It was made possible.

[Means and Actions for Solving the Problems]

In order to achieve the above-mentioned object, the present invention horizontally mounts a plurality of crossbars provided with panel holding means between a pair of transfer bars arranged side by side in the press body, and takes out the transfer bar from the press body. 2 due to the power
In a transfer press that moves the panel 19 by moving in a dimensional direction, a lift equalizer rod that drives the transfer bar in the lift direction is connected to a forced lift cylinder via a carrier, and the crossbar is provided near the carrier. Further, by providing the locking means for locking the panel holding means when the panel holding means is forcibly lifted to the position where it does not interfere with the panel check, the crossbar and the panel holding means are used when the press body is stopped and the panel is checked during press forming. It is intended to provide a panel check device for a transfer press, which can check a panel without being disturbed by.

〔Example〕

 An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 is a pair of transfer bars provided in a transfer press body (not shown). Both ends and a central portion are vertically movably supported by a rack rod 2, and both sides of the rack rod 2 are supported. A balance cylinder 3 for urging the transfer bar 1 upward is provided.

A lift equalizer rod 4 is provided below each transfer bar 1 in parallel with the transfer bar 1.
The rack 4a provided on these equalizer rods 4 is meshed with the pinion 5, and the pinion 5 is meshed with the pinion 6 meshed with the rack rod 2 as the lift equalizer rod 4 reciprocates. The transfer bar 1 is vertically moved while maintaining the horizontal state.

On the other hand, one end side of each lift equalizer rod 4 is pivotally attached to the upper end of a lift lever 8 whose lower end is pivotally supported.

Each of the lift levers 8 is in circumferential contact with a lift cam 9 which is rotated by the power taken out from the press main body, and is swung around a pivot portion in accordance with the rotation of the lift cam 9 to reciprocally drive the lift equalizer rod 4. At the same time, a carrier 11 is attached to a pivotally connecting portion of the lift equalizer rod 4 and the lift lever 8.

Rollers 12 provided on both sides of the carrier 11 are supported by guide rails 13 as shown in FIG. 3, and are movable in the direction of the lift equalizer rod 4 by a forced lift cylinder 14.

A locking portion 11a is provided on the upper portion of the carrier 11 so that the locking portion 11a can be moved back and forth in a direction orthogonal to the moving direction of the carrier 11 by the lock cylinder 15.
It can be locked with 16.

On the other hand, a plurality of crossbars 18 are laid horizontally between the transfer bars 1, and a panel 19 is provided on each of the crossbars 18.
A panel holding means 20 such as a vacuum cup for adsorbing is attached.

The operation of the transfer bar 1 will be described below.
Driven in the dimension, the panel holding means 20 provided on the crossbar 18 adsorbs the panel 19 and conveys it to each processing station.

When the press body is stopped to check the panel 19 during panel molding, the transfer bar 1 driven by the power taken out from the press body is also stopped.

In this state, the panel holding means 20 is attracted to the panel 19 on the lower die 21, so that the panel holding means 20 is first released, and then the lift equalizer rod 4 is pulled by the forced lift cylinder 14 via the carrier 11. And forcibly lift each transfer bar 1.

And a crossbar that is placed horizontally between each transfer bar 1.
As shown in FIG. 4, 18 rises to a height where it does not interfere with the upper die 22, and when this is detected by the proximity switch 23, the lock pin 16 is advanced by the lock cylinder 15 to lock the locking portion 11a of the carrier 11. And lock the carrier 11 in its position.

In this state, a worker enters the press body to check the panel 19 so that the crossbar 18 and the panel holding means are
Since the 20 does not interfere with the panel check, the panel 19 can be easily checked.

On the other hand, when the molding operation of the panel 19 is started, first, the lock pin 16 is retracted by the lock cylinder 15 and the carrier 11 is moved.
1 is released, and then the forced lift cylinder 14 is extended to lower the transfer bar 1 to its original position.

[Effect of device]

As described in detail above, the present invention can forcibly lift the crossbar laid across the transfer bars and the panel holding means attached to the crossbar after stopping the press body to check the panel to a position where it does not interfere with the check. By doing so, it becomes possible to easily and quickly check the panel by entering the press body even during the molding of the panel.

Also, because the transfer bar is locked at the forced lift position by the locking means, the transfer bar and the crossbar that is laid across it will not fall carelessly during the panel check work, so the panel check work can be performed. You will be able to do it completely.
