Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacking tray separating apparatus for separating stacked trays one by one by a suction mechanism.

[0002]

2. Description of the Related Art A conventional technique will be described with reference to FIGS. The tray support portion 3 that guides and supports the tray 2 is screwed into a vice screw 7 having a handle 8. When the vise screw 7 is rotated, the tray support part 3 is opened and closed by the vise mechanism 12 with the surface A of the tray 2 as a reference.
Protrusions 9 for holding the lowest tray 30 are provided below both ends of the tray support portion 3, and a suction device 19 for sucking the tray 2 and a suction device are connected below the tray 30. Dozens of trays 2 are stacked in the tray support portion 3,
It is pressed downward by its own weight, and it is 1 from the suction device.
It was peeled off one by one.

[0003]

The conventional stacking tray separating device is a vise mechanism which opens and closes on the basis of either the width or the length of the tray as described above. When the tray support portion was brought into close contact with the tray, the tray did not descend downward and stopped midway, so that the tray could not be peeled off.

On the contrary, if the clearance between the edges of the stacked trays and the tray support is too large, the edges of the trays will not be caught by the projections for holding the lowest tray provided at the lower ends of both ends of the tray support. In some cases, several trays were peeled off at one time.

When using trays of the same type having the same width or length, the trays need only be set once.
Although it is possible to separate the sheets one by one, it is difficult to adjust the clearance between the edge portion of the tray and the tray support portion when using a tray of a type having a different width or length.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to facilitate the tray replacement work even if the size changes depending on the type of tray.

[0007]

The above object is to provide a tray support portion for guiding and supporting the trays stacked on the machine base, and the tray support portion has projections for holding the lowest tray at the lower ends of both ends and the tray. In the stacking tray separating device, which has a vise mechanism that opens and closes on the basis of either one of the width or the length of the above, and has a suction device that suctions and takes out the lowest tray one by one below the tray support portion, One end is rotatably supported at an appropriate position of each tray support portion on both sides which is opened and closed by the vice mechanism, and a gauge is formed so as to be constantly in contact with an edge portion of the tray. This is accomplished by providing an indicator with a display that displays the distance to the tray edge.

[0008]

In the laminated tray separating device configured as described above, since the tray supporting portions are opened and closed based on either the width or the length of the trays stacked by the vise mechanism, the tray supporting portions are provided on both sides of the tray supporting portion. The gauge always contacts the edge of the stacked trays. The position of the gauge and the inner surface of the tray support at this time is such that the gauge protrudes toward the edge of the tray more than the inner surface of the tray support, and is a projection that holds the lowest tray provided at the lower ends of both ends of the tray support. It is designed to fit the display part provided on the indicator so that people will not travel on business. By vertically moving the suction device in communication with the suction device in this state, both edge portions of the lowest tray are held by the protrusions, so that the trays can be separated one by one.
