Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stand for a packaging conveyor having a large number of stands for supporting laminated sheets.

Conventionally, when stacked sheet-like objects are placed on a conveyor L with a large number of stands spaced apart from each other on the conveyor surface and then packaged and conveyed, a cross-sectional opening is used to prevent damage to the periphery of the sheet-like objects. It is necessary to fit a protective metal fitting of the shape,
It is not always the case that the sheet-shaped conveyed object is supported on the stand with a peripheral edge sufficient to fit the protective metal fittings, but the peripheral edge of the sheet-shaped conveyed object is often supported by the stand.

This is because the sheet-like conveyance material is placed on the conveyor at any time regardless of the position of the stand.

Therefore, it is conceivable to control the timing of placing the sheet-like conveyed object on the conveyor by detecting the stand position so that the peripheral edge of the conveyed object is not supported by the stand, but since the shape of the supporting surface of the sheet is diverse, Depending on the distance between the stands and the shape of the seat support surface, it may not be possible to avoid supporting the peripheral edge of the seat on the stand.

Therefore, in order to fit the protective metal fittings around the periphery of the laminated sheets 1 to 1-shaped conveyed objects, as described above, either select a position on the conveyor where the periphery of the sheet is not supported by the stand, or use a stand. It is necessary to adjust or change the standing interval in accordance with changes in the shape of the seat support surface, or to lift the periphery of the heavy laminated sheet from the stand, but these tasks require complicated detection and control means. , or a complicated movable adjustment structure of the stand relative to the conveyor, or excessive labor accompanied by danger, etc., so it is necessary to provide a top end that can be freely raised and folded at the upper end of the stand, as disclosed in, for example, Japanese Patent Application Laid-open No. 52-29395. By folding down the top when not needed, a space is created around the periphery of the sheet-like conveyed object, making it easier to fit the protective metal fittings.

However, the tops of the conveyor that are lying down at the rear in the direction of movement of the conveyor do not stand up even after the conveyor reaches the conveyance side again after the driving and driven chain wheels have been suspended, and are in a lying position, so each top has to be manually removed. It had a major drawback in that it could not support the laminated sheet unless it was in a standing position.

The present invention eliminates the drawbacks of the conventional ones as described above, and an embodiment thereof will be described below with reference to the drawings. It moves along guide rails 3, 3 provided on the conveyor frame 2, and is suspended between the driving chain wheel and the driven chain wheel.

A large number of slats 4, 4, . The stand 6.6 is attached to the slat so as to be movable in the width direction of the conveyor, and the distance between the stands 6 and 6 can be adjusted to increase or decrease depending on the size of the rir of the conveyed object.

For example, the conveyed object 5' shown by the two-dot chain line in FIG.
is narrow in width and is supported by stands 6', 6' which are moved and adjusted to the positions indicated by two-dot chain lines with narrower spacing.

As is clear from the enlarged front view of FIG. 3, the top 7 of the stand 6.6 is pivotally connected to the stand 6 by a hinge 8, for example, so that it can be raised and lowered, and the top 7 and the stand 6 are connected to the joint surface when the top is erected. In the embodiment shown in FIG. 4, a magnet is attached as the attraction member 9 to the joint surface of the top 7 when the stand 6 is raised. Alternatively, a magnet may be attached to the top upright joint surface of each of the top portion 7 and the stand 6.

Therefore, before the stand reaches the sheet-shaped conveyed object loading position, the interval between the stands is adjusted depending on the size of the sheet supporting surface on which the sheet is placed, and the top of the stand and protective metal fittings that may support the peripheral edge of the sheet are adjusted. The top part that gets in the way of fitting is laid down around the hinge.

In such a case, even if a seat is placed on the stand 6, the stand 6, which is in the seat peripheral support position, will
Since the height is lowered by the height of , the peripheral edge of the seat is not supported by the stand and a gap is created, making it easier to fit the protective fitting 10 onto the peripheral edge of the seat as shown in FIG.

The laminated sheet-like conveyed object covered with the protective fitting 10 is thus supported on the stand, packed, and conveyed off the conveyor.

When the stand on the conveyor from which the conveyed articles are carried is hung around the driving chain wheel and the driven chain wheel, the top part 7 which is in the lying position is reversed and automatically returns to the upright position.

In other words, the top that has been laid down by the forward force of the traveling force is reversed and becomes an upright state when the driving chain wheel is suspended, and the top that has been laid down by the forward force of the traveling force is reversed and becomes the upright state when the driven chain wheel is suspended. The top, which has been inverted to the upright state, is attracted to the joint surface with the stand by a suction member 9, such as a magnet, and is held upright.

Therefore, when the driven chain wheel of the stand is suspended and the stand reaches the conveyance side, all of the fallen tops are maintained in an upright state.

As described above, in the present invention, since the top of the stand that supports the sheet is pivotally attached to the stand so that it can be raised and lowered, only the top of the stand, which becomes an obstacle when fitting the protective metal fittings to the peripheral edge of the sheet conveyed object, can be folded down. In addition, when the top of the fallen top is suspended from the driving chain wheel and the driven chain wheel, it is reversed and erected and held by suction on the stand. The return to the standing position does not require any special manpower and is carried out automatically as the conveyor operates. When the driven chain wheel is suspended and the conveyor reaches the conveyor side, all the fallen tops return to the standing position and the next one is immediately carried out. Sheet supported conveyance becomes possible.

Since the present invention is configured as described above, it is possible to easily fit the sheet peripheral edge protection fitting onto a sheet having any type of support surface with an extremely simple structure, and the stand suspends the driven chain wheel on the conveying side. When this is reached, all the stands are ready to support the sheets, so the packaging and conveyance work is carried out extremely efficiently, and this conveyor has an extremely superior effect compared to conventional sheet packaging conveyors.
