[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supply table for holding and supplying sheets one by one by a vacuum suction device.

[0002]

2. Description of the Related Art Printed paper printed by a web rotary printing press and a sheet-fed rotary printing press and conveyed is formed into signatures by a folding machine, and then stacked at a predetermined number of sheets, and the collected signatures are bound by a binding machine. The block-shaped signatures B, which have been bound together in a block shape using a tape, a string, or the like, are stacked on a pallet C for transportation and storage as shown in the figure. When stacking the flocked signatures B on the pallet C, the sheet D (printing paper, vinyl sheet) is covered on the upper side and stacked every one or two or several steps so as not to collapse. Like that.

[Problems to be solved by the invention]

[0003] The sheet D for preventing the collapse of the load is generally referred to as a slip sheet. In general, the sheet is supplied by stacking the slip sheets on a horizontal sheet supply table in the same manner as a normal sheet supply. In this order, the sheets were fed onto the block-shaped signature on the pallet by vacuum suction sheet feeding means such as a robot arm. One of them was unexpectedly peeled off and dropped down, which sometimes hindered the stacking operation.

According to the present invention, two sheets are supplied by a sheet supply means in an overlapping manner, or a lower sheet is supplied during the supply.
Improve the sheet supply table so that the sheets do not fall off unexpectedly and fall down, and do not interfere with the stacking work,
An object is to ensure that sheets can be supplied one by one.

[0005]

According to the present invention, a horizontal surface 1 is provided.
A sheet feeding table A having a curved or curved curved surface 3 constituted by an inclined surface 2 continuously inclined higher from the horizontal plane, wherein both ends of the curved or curved curved surface 3 are provided at the center in the width direction. The sheet supply table is provided with a convex portion 5 having an uppermost surface 4 along a straight line connecting the portions 1a and 2a.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to embodiments.
FIG. 1 shows an embodiment of a sheet supply table A according to the present invention. The horizontal plane 1 is substantially horizontal or almost horizontal (for example, inclined within about 5 ° with respect to the horizontal).
For example, an upper surface having an inclined surface 2 that rises continuously or intermittently at an angle of about 10 ° to 45 ° with respect to the horizontal plane, and has a curved surface that is bent or curved by the horizontal surface 1 and the inclined surface 2. The platform 3 is configured. The horizontal plane 1 and the inclined plane 2 do not necessarily have to be completely flat,
It may be curved.

At the center in the width direction above the curved surface 3 formed by the horizontal surface 1 and the inclined surface 2, an uppermost surface 4 along a straight line connecting one end 1 a and the other end 2 a of the curved surface 3 in the bending direction.
Is provided. In addition, both side surfaces 5a, 5 descending from the uppermost surface 4 of the convex portion 5 to reach the horizontal surface 1 and the inclined surface 2
a need not necessarily be vertical, and may be a gentle slope.

[0008] In one embodiment of FIG.
Is a predetermined linear width w from the one end 1a to the other end 2a (when the width W of the curved surface 3 is, for example, w = (1
/ 3) W to (1/10) W).

The flat surface 4a of the uppermost surface 4 of the convex portion 5 may be slightly protruded from the upper surface at one end 1a and / or the other end 2a of the curved base surface 3, whether or not it is not. May be. Further, the uppermost surface 4 of the convex portion 5 does not necessarily need to be the flat surface 4a, and may have a rounded shape, for example.

The operation of supplying sheets (interleaf sheets) using the sheet supply table A of the present invention will be described below with reference to FIGS. FIG. 3 is a perspective view of a state in which a slip sheet D is stacked on the sheet supply table A according to the present invention, and the slip sheet D is disposed along the flat convex portion 5 of the sheet supply table A on the upper side thereof. D
Is loaded on the center portion D1, and both sides D2, D in the width direction of the
2, the central part D1 is loaded higher.

On one end 1a side of the horizontal surface 1, a vacuum suction type sheet in which air suction plates 7 are respectively attached to the lower ends of vertical air suction arms 6, 6 above both sides of the central convex portion 5, respectively. Supply means E is arranged.

The suction arm 6 is movable in the vertical direction (X direction) and the front and rear direction (Y direction). As shown in FIG. 3, first, the suction arms 6 and 6 are moved downward in the X direction. After the air suction operation is performed while pressing the suction disk 7 above the slip sheet D, the suction sheet 7 is moved upward in the X direction as shown in FIG. 6, 6 in the Y direction (the front end 1a of the sheet feeding table A).
(The outer front side) to supply the slip sheet D onto the block signature on a predetermined pallet. At the time of supply, an air blow a of appropriate strength is blown out from the same surface as the slip sheet D (sheet) in the direction opposite to the supply direction, or from the lower side, or the upper and lower sides, to supply. be able to.

[0013]

The sheet supply table A of the present invention has a curved or curved curved surface 3 composed of a horizontal surface 1 and an inclined surface 2 which is continuously inclined higher from the horizontal surface, and the center of the curved surface 3 in the width direction. A convex portion 5 having an uppermost surface 4 extending along a straight line connecting both ends 1a and 2a in the bending or curving direction, and an appropriate step between the upper surface 4 of the convex portion 5 and the horizontal surface 1 and the inclined surface 2; Is formed, a plurality of or a large number of interleaved sheets (sheets) D stacked on the curved surface 3 of the supply table A are arranged such that their widthwise ends are along the stepped portions. Since the sheets are stacked while maintaining the proper posture, an appropriate shift and gap are obtained between the sheets of the slip sheet D at this time, and the close overlap due to the stacked weight of the slip sheet D can be reduced. Therefore, self-adhesion of the slip sheets D can be prevented, and the sheets can be supplied with good paper handling.

[0014]

[Effects of the Invention] The sheet supply table of the present invention is used for stacking work in which two sheets such as slip sheets are supplied in an overlapped manner, or one of the lower sheets is unexpectedly peeled off during the supply and drops downward. There is no problem and it is possible to supply sheets one by one without fail, which is of practical value.
