Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel holding device for holding a panel, which is a workpiece, when processing a panel such as an exterior board for building materials.

When attaching sashes or picture frames to panels, or processing joints such as screw holes on the panel surface, it is common to perform the work with the panel being processed standing upright.

In this case, the panels that have been worked on must be carried out one by one from the working position, so the panels are held upright on the transport rollers, and as soon as the work is completed, the holding means is released and the panels are sent out using the transport rollers. This is often done.

However, until now, there has been no panel holding device that can safely and effectively hold and transport panels.
Panels often fell over during work, and panel holders often got in the way of work.

The present invention was made in view of the above circumstances, and an object of the present invention is to provide a panel holding device that can safely and effectively hold and carry out a panel, which is a workpiece material.

This will be explained below.

The panel holding device according to the present invention is pivotally supported on a base,
and a fairing plate having a panel holding surface on the front side is made swingable by a tilting cylinder disposed between the base and the fairing plate has a panel placed on the holding surface. A clamping cylinder is attached to operate a presser that can be clamped therebetween, and the clamping cylinder can be operated in a direction to release the clamping of the panel only when the tilting cylinder is in a predetermined state. It is characterized by what it did.

To explain this in more detail based on examples, the first
The figure is an external view (side view) of a panel holding device covered by the present invention, in which a straightening plate 2 having a holding surface 21 on the front side (left side of the figure) is pivoted to a base 1 by a pin joint or the like at a connecting part 3. supported.

A tilting cylinder 4 is disposed between the leveling plate 2 and the base 1.

The holding surface 21 of the straightening plate 2 is tilted backward so that the upper part is toward the rear (to the right in the figure) when the tilting cylinder 4 is contracted, but when the tilting cylinder 4 is extended, the holding surface is vertical.

An upper clamping cylinder 5 for operating the upper presser 1 is attached to the upper part of the leveling plate 2, and a lower clamping cylinder 6 for operating the lower presser 8 is attached to the lower part of the leveling plate 2.

When these two upper and lower clamping cylinders 5 and 6 are extended, the upper and lower two pressers 7 and 8 press the panel 13 toward the holding surface 21 of the straightening plate 2, so that the panel 13 is held against the receiving surface 21 provided on the holding surface 21. is sandwiched between the roll 10 and the presser rolls 11 and 12 provided at the tips of the pressers, and is held securely.

Conversely, when the two clamping cylinders 5 and 6 are contracted, the two pressers 7 and 8 are in the state shown by the chain lines in the figure, and the clamping of the panel is released.

Note that a conveyance roller 9 for conveying the panel is provided below the panel 13.

It is preferable to operate the tilting cylinder and the two clamping cylinders using compressed air in terms of speed, and in this example, we will explain the case where compressed air is used, but depending on the case, it may be possible to use hydraulic cylinders etc. It will be done.

FIG. 2 shows an example of a circuit for operating these tilting cylinders and two clamping cylinders.

In Figure 2, valve ■.

The compressed air introduced through advances in the direction of the arrow and enters the valve V1 for actuating the tilting cylinder 4.

When this valve v1 is switched in the direction in which the tilting cylinder 4 is retracted, the compressed air passes through the check valve C■, and the two valves v2. v3 and therefore only then these valves v2. (2) By operating 3, the clamping cylinders 5 and 6 can be operated.

Conversely, when valve (1) is switched in the direction in which the tilting cylinder 4 is extended, compressed air is no longer supplied to valve (V2 + (3)), so that the clamping cylinders 5, 6 cannot be operated.

Since the circuit for operating the tilting cylinder and the clamping cylinder is configured in this way, the panel 13 clamped between the pressers 7 and 8 and the support on the holding surface 21 and the roll 10 can be moved when the tilting cylinder 4 contracts. , the holding surface 21 of the leveling plate 2 is released from the grip only when it is tilted back, ie the panel itself is also tilted back.

In this case, since the panel itself is tilted backward along the holding surface 21, there is no danger of it falling forward even if the presser is removed, and the panel is processed in this state.

Further, when the holding tools 7 and 8 are released, they are moved away from the surface of the panel as shown by the chain lines, so that they do not interfere with the work.

When the panel machining work is completed, operate the valve ■2゜■3 to extend the clamping cylinders 5, 6, and as a result, the pressers 7, 8 and the receivers on the holding surface are held together by the roll 10 and the panel 1.
Hold 3.

Thereafter, the valve V1 is operated to extend the tilting cylinder 4.

This puts the panel in a vertical position, but as mentioned above, the holding cylinders 5 and 6 cannot be operated in this state, so even if valves v2 and v3 are switched inadvertently, the pressers 7 and 8 will not be removed from the panel. Therefore, the panel is securely held and therefore safe.

When the panel is held vertically, it is held between the presser rolls 11 and 12 and the support roll 10, and the entire panel is placed on the transport roller 9, so it can be easily transported. can do.

In this way, using this panel holding device allows work to be carried out extremely effectively.

As explained above, the panel holding device according to the present invention swings the straightening plate, which is pivotally supported by the base and has a panel holding surface on the front, by a tilting cylinder disposed between the base and the base. When the tilting cylinder is in a predetermined state, and the adjusting plate is provided with a clamping cylinder that clamps the panel placed on the holding surface between it and operates the hanging presser, and the tilting cylinder is in a predetermined state. Since this device is capable of operating the clamping cylinder in the direction of releasing the clamping of the panel only when the panel is clamped, the panel can be held and carried out safely and effectively.
