Description

[Detailed description of the invention] [Industrial application field] This invention relates to a side guide device for a sheet feeder that supplies a plate-shaped sheet member to a processing machine such as a press machine, and is particularly a versatile side guide device for a sheet feeder. Regarding.

[Conventional technology]

Generally, in a sheet feeder that supplies plate-shaped sheet members to a processing machine such as a press machine, a sheet member 3 sent to a sheet feeder 1 by a roller conveyor 2 is once positioned on this sheet feeder 1, as shown in FIG. Then, this positioned sheet member 3 is conveyed to the press machine 4 by a conveyance device using a vacuum cup or the like. In this case, the positioning of the device sheet member on the sheet feeder 1 is performed in the front-rear direction and the width direction.
This is done by providing a positioning plate 6 and stopping the sheet member 3 sent to this positioning plate 6. The positioning of the sheet member 3 in the width direction is performed by side guide devices 5 provided on both sides of the stopped sheet member.

An example of a side guide device for this sheet feeder is as shown in FIG. There is one in which a press plate 10 guided by a guide member 9 is connected to an air cylinder 11 and moved along the width direction of the sheet feeder 1. This presses the side edges of the supplied sheet member 3 to position it in the width direction.

Furthermore, there is a side guide device for the second sheet feeder as shown in FIG. This is done by rotatably supporting the press plate 13 downward on the base member 14, swinging the press plate 13 with an air cylinder 15, and pressing the press plate 13 against the side edge of the sheet member 3 to position it. It was designed to do this.

[Problem that the invention attempts to solve]

Incidentally, the sheet members supplied to the sheet feeder 1 have the same shape for each lot, but if the lot is changed, the shape of the sheet member will change. In this case, it is necessary to use the side guide device of the first sheet feeder shown in FIG. 5 and the side guide device of the second sheet feeder shown in FIG. 6, and each time the device is replaced and reinstalled. In other words, a sheet member 1 having a large width and inclined sides as shown in FIG.
6, when the side guide device of the second sheet feeder shown in FIG. 6 is applied, the sheet member 16 can be positioned at the lateral inclined portion even if it does not have a rough positioning function in the horizontal direction, Moreover, when conveying after positioning, the press plate 13 rotates and the sheet member 16 can be used without any problem without interference. However, when this sheet member 16 is applied to the side guide device of the first sheet feeder shown in FIG. So I can't actually use it. Furthermore, in the case of a sheet member 17 whose sides are not inclined as shown in FIG. 8, it is necessary to roughly position the sides in the horizontal direction.
The side guide device of the first sheet feeder shown in FIG. 5 can be used. However, the sixth
If you try to apply it to the side guide device of the second sheet feeder shown in the figure, it will not be possible to roughly position it in the horizontal direction, and the pressing plate 13 will rotate during positioning, causing the sheet member 17 to float. cannot be used for

[Means for solving problems]

The present invention solves the above problems and obtains a versatile side guide device for a sheet feeder by pressing a pressing plate against the side edge of a plate-shaped sheet member fed to a processing machine and positioning the sheet member in the lateral direction. In a side guide device for a sheet feeder, a guide device that guides a pressure plate in the horizontal direction and urges the pressure plate to a neutral position in the horizontal direction, and a shaft that allows the pressure plate to rotate downward on this guide device. Pressing plate movement comprising a supporting member supporting the pressing plate, a regulating means capable of regulating the rotational position of the pressing plate or prohibiting the rotation, and a driving means driving the pressing plate in a substantially horizontal direction above the pivoting portion. A device was installed.

〔Example〕

Embodiments of the side guide device for a sheet feeder according to the present invention will be described below with reference to the drawings. 1st
3 to 3 show an embodiment of a side guide device for a sheet feeder according to the present invention. In this embodiment, the side guide device of the sheet feeder is provided at the same position as the side guide device of a conventional sheet feeder, and the side guide device of the sheet feeder is provided at the same position as the side guide device of the conventional sheet feeder.
A guide member 21 is provided in the horizontal direction, and a slide member 22 is inserted into this guide member 21. Coil springs 23 and 24 are provided on both sides of this slide member 22, and the slide member 22 is placed approximately at the center of the guide member 21. It is used as a guide device. This slide member 22
has two legs 25 and 26 erected, and the first leg 25 provided on the base side serves as a support member.
A press plate 28 is rotatably supported via a base 27 . The base 27 extends to the second leg 26 side, and this end is attached to the second leg with a removable pin 29, and a step 26a is provided on this leg to receive and press the base 27. The inward rotation of the plate 28 is restricted and serves as a restriction means.

An air cylinder 30 is provided as a driving device between the base 27 and the mounting portion 20a erected at the end of the base member 20, so as to drive the base 27 along a substantially horizontal direction.

Therefore, according to this embodiment, the pin 29 connects the base 27.
When the air cylinder 30 is operated with the second leg portion 26 connected to the base portion 27, the base portion 27 moves horizontally along the guide member 21 together with the slide member 22, as shown in FIG. 28 also base 27
move with

Furthermore, when the pin 29 is removed and the air cylinder 30 is operated in the pulling direction without connecting the base 27 and the second leg 26, the base 27 moves slightly along with the slide member 22 as shown in FIG. After moving in the horizontal direction, the base 27 rotates outward about the pivot point with the first leg due to the pressing force of the coil springs 23 and 24.

On the other hand, when the air cylinder 30 is operated in the pushing direction, the pressing plate 28 rotates inward, and then the base 27 comes into contact with the stepped part 26a of the second leg 26, and the pressing plate 28 rotates inward. It does not rotate further inward, but moves in the horizontal direction together with the slide member.

Therefore, according to this embodiment, the operating state of the side guide device of the sheet feeder can be changed by connecting or disconnecting the base portion 27 and the second leg portion 26 using the pin 29. It can accommodate sheet members of various shapes and has versatility.

In this embodiment, a pin or the like is used as the restricting means, but the present invention is not limited to this, and it goes without saying that other means may be used. It goes without saying that other means may be used as the driving means.

[Effect of idea]

As explained above, according to the present invention, the pressing plate of the side guide device of the sheet feeder can be operated by selecting the moving direction of the horizontal or rotational direction. The movement format can be selected and it can be made versatile.
