PURPOSE:To aim at shortening the time required for paper stacking, by supporting an upper paper stacking frame shiftably in both horizontal and vertical directions on a lower paper stacking frame which is made to be shiftable only in a sideway direction in design, while making up a device possible to operate the upper stacking frame independently and both upper and lower paper stacking unificly. CONSTITUTION:A paper stacking frame 24 is landed on a bottom surface of a pit 23, positioning both upper and lower paper stacking blocks 29 and 33 right with a scale 53 as a criterion. Next, a pallet on which paper is placed in accord with a ruller is mounted on the upper paper stacking block 33, then handles 49 installed in both side symmetrically are rotated in each opposite direction, rotating the upper paper stacking block 33 horizontally centering on a bearing (unillustrated herein), its position is corrected so as to cause the pallet to be paralleled with a front stop 52. In addition, both handles 49 are rotated in the same direction, shifting the upper paper stacking block 33 in parallel to the front stop 52, and paper 7 is made to hit the front stop 52 in an accurate manner. Then, both upper and lower paper stacking blocks 29 and 33 are unified in one and shifted on rollers. With this constitution, shortening in the time required for paper stacking is well promoted, thus operation efficiency is improved ever so better.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feed stacking device for stacking paper to be fed to a printing device below a paper feed sucker device in a sheet-fed printing press.

In printing operations using a sheet-fed printing press, a large number of papers are stacked on a paper stack on a paper stack bar suspended by a lifting chain of a paper feeder, and the paper is sucked one by one from the top layer by a suction device. The image data is supplied to the printing device via the viewing device. As the amount of paper decreases due to paper feeding, the lifting chain is automatically wound up to maintain the upper end of the stacked paper at a constant height at all times. When the stack of paper on the paper stack runs out, the machine is stopped, the lifting chain is rewound, the paper stack is lowered together with the paper grain bar, and then new paper is loaded and printing begins. Previously, work had been done to restart the

However, with this, the machine has to be stopped for a long time to load paper every time it runs out of paper, which increases non-printing time and significantly reduces work efficiency. A continuous paper-feeding paper stacking device as shown in the second half has been proposed and used. In other words, two lifting chains 2 and 3 each consisting of four chains suspended from a paper-feeding frame 1 are used. ,
A pair of paper stacking bars 4 and 5 are suspended at the front and rear, and when printing starts, paper 7 is stacked only on the paper stacking board 6 placed on the lower paper stacking bar 5, and the paper is fed. It is carried out. Then, the paper stack bar 5 rises as the paper is fed, and when the stack becomes less than half, the thread support rod 8 is inserted into the groove of the paper stack 6 and supported by the upper lifting chain 2. , the lifting chain is switched from the lifting chain 3 to the lifting chain 2. Paper stack bar 5 that became idle while paper feeding continued
is written down, a new paper 7 is stacked on the paper stacking board 6, and the paper T is raised at 1, where the upper surface touches the paper support a8. When the paper on the paper support rod 8 runs out, the rod ε is removed to continue feeding the paper without interruption.

However, since 1995, such paper stacking devices have made continuous printing possible, but they have to stack the next paper in a low and narrow place while the machine is running, which reduces work efficiency.
The drawback is that it is not only inferior in terms of safety, but also that it is not possible to take a sufficient view of the stacked sheets of paper 7. Therefore, another paper stacking apparatus 10 as shown in the right half of FIG. 1 has been proposed and widely used as an accessory to this type of paper stacking apparatus.

That is, behind the paper feed tear', a ball 12 connected to the paper feed frame 1 by a stay 11 is erected on the floor, and each ball 12 has a pair of front stops 13.
and a horizontal support 14 are attached so as to be openable and closable in the width direction of the paper 1. During the printing operation using the paper 7 in the paper feed frame 1, the millet farmer pulls the trolley 15 onto the rail, positions it behind the hole 12, and places the paper 7A on the paper stack 6 placed on the trolley 15. Load. At this time, paper 7A is 13
The front end and both side ends are aligned with the auxiliary light 14. When the amount of paper 7 being fed is running low, open the front cover 13 and supplementary light 14 to the left and right, push the trolley 15 into the paper feed frame 1 along the rail, and remove the stack of paper in the idle body as described above. The bar 5 is hooked to the paper stack board 6 and the paper stack board 6 is raised. When the paper runs out, the paper support rod 8 is removed and the paper feed is switched to new paper.

This configuration makes loading work easier,
In addition, horizontal loading can be ensured, but the lifting chain 2
, 3. In order to improve workability by facilitating replacement work, the space between the paper feed frame 1 and the ball 12 must be widened, and the loading of the trolley 15 is difficult. The disadvantage was that it was not a scale and the overall length of the machine board was longer.

In addition, the present applicant proposed an f7B inspection device as shown in Figure 2 of N'r in Utility Application No. 181305/1983. In this process, the paper 7 is loaded onto the bar (17) on the hand lift 16 at another location in the factory, aligned with the ruler, and then carried into the paper feed frame 1. J1
4A is provided on the paper feed frame 1 side. Further, at the four corners of the floor pit 18 provided in the paper feed frame 1, there are fixed saucers 19 consisting of a race and several steel balls parallel to each other in its current groove. The paper stacking force that forms the same plane as the floor surface is placed so as to be movable in each direction. The pallet 17 is then carried into the paper feed frame 1 and lowered from the hand lift 16 onto the stacking platform 20.
Since it is movable in each direction on the tray 19 together with the paper table 20, by moving it, the edge of the paper IB on the pallet 1γ is aligned with the front plate 13A and supplementary light 14A, and then the above-mentioned Paper feeding is started in the same manner. By doing this,
Although it is easier to position the paper, and the paper 7B is easier to carry in compared to the one shown in Fig. 1, and the overall length of the machine is also shorter, the pallet 17 is not properly fixed at the positioning point. Positioning by pushing and pulling by hand makes it difficult to make fine adjustments, and it has not always been possible to achieve satisfactory performance. Further, in both of the apparatuses shown in FIGS. 1 and 2, the paper stacking bar 5 must be unlatched and removed, making it difficult to stack paper in a short period of time.

The present invention has been made in view of the above points, and a lower M:. On this lower IK M table, an upper paper stacking table which can be rotated in the horizontal direction about the center support part is placed so as to be movable in the front and back direction, and the upper and lower ffi', & tables are integrated. By providing an operating device that moves the upper paper stacking table left and right with respect to the paper stacking frame, and an operating device that moves the upper paper stacking table separately on the left and right sides with respect to the lower paper stacking table after cutting, it is possible to reduce paper processing time and labor. The present invention provides a sheet feeding bed and installation for sheet-fed printing plates, which is designed to reduce the amount of paper-fed printing plates and reduce the machine installation space. Embodiments of the present invention will be described in detail below with reference to the drawings.
