Description

[Detailed description of the invention] (Industrial field of application) Regarding a processing device for a stack of sheets in which a large number of sheets are stacked, in particular, sheets stacked in multiple stages by a receiving plate and a frame plate that are larger than the stack of sheets. The present invention relates to a processing device for printed paper.

(Prior art) When performing multicolor printing or front and back printing using a sheet-fed printing press, the printing paper is stacked at the paper output section of the printing machine in preparation for the next printing or cutting, but immediately after printing, the ink on the printing paper is Because the paper is not sufficiently dry, when it is piled up in a high pile called stacking, ink transfers to other printing papers, resulting in set-off. In order to prevent this set-off, a method known as board removal is used, which uses a receiving plate larger than the printing paper and a frame plate to support the receiving plate and maintain a constant spacing at each height within a range that does not cause set-off. ing. This board cutting is often done in 5 to 6 layers at intervals of 10 to 20 cm. The printing paper that has been boarded in multiple stages in this way is taken out from the paper output section of the printing machine in its boarded state, and the ink is allowed to dry, and the receiving plate and frame board are removed for the next process. Stack the printing paper in a pile while removing it.

Conventionally, the work for converting the boarded paper into stacks, that is, the separation and movement of the boarded printing paper, and the processing of the receiving plates and frame plates, has been performed manually. This manual work was tedious and required a considerable amount of physical labor. Therefore, there has been a strong desire to automate such work.

(Problems to be solved by the invention) The present invention was created in view of the above points, and the printed paper is cut out and stacked in multiple stages, and the paper that comes from the paper output section of the printing machine is used for the next overlapping printing. , back printing,
In addition, we provide a device that automates the removal of printing paper, receiving plate, and frame plate when printing is completed and transferred to a cutting machine, etc., and also plays a role in automating the entire process related to paper handling at a printing factory. It has a relatively inexpensive and simple structure,
The purpose is to provide a device that is easy to handle.

(Means for Solving the Problem) A processing device for printed paper stacked in multiple stages at intervals using receiving plates and frame plates,
A means for separating and transporting a certain amount of printed paper from a stack of printed paper on a receiving plate, a means for removing an empty receiving plate after all the loaded printed paper has been processed, and a means for removing a frame plate on the next stage receiving plate. The means for separating and transporting the printed paper includes a transport table configured as an air table for receiving the printed paper separated by the separating means and transporting it to the next process, and having a receiving plate holding device on the lower surface, The means for removing the receiving plate includes the transfer table that holds and transfers the receiving plate by the receiving plate holding device, the rod that can be raised and lowered to receive the receiving plate from the transfer table, and the rod that has a hole through which the rod can be tilted. It is characterized by comprising a receiving plate for receiving the receiving plate.

(Example) Hereinafter, the present invention will be described in detail with reference to figures showing examples.

1 to 9 are diagrams showing or explaining one embodiment of the present invention.

Figure 1 is a side view showing the entire device of this embodiment;
The figure is a partially omitted perspective view of the same device.

The stacked printing paper P, which has been removed by the receiving plate 1 and the frame plate 2 onto a vertically adjustable table lifter 3 (simply shown), is mounted on a known printing paper quantitative separator 4 (number 1), which is shown surrounded by a dashed line. Details are shown in Figure 3)
Alternatively, a certain amount of paper is separated from the pile of stacked papers by another separating device having the same purpose and transferred to the transfer table 5. The transfer table 5 is configured as an air table, and the transfer table 5 carries the separated quantitative paper P' and is moved to the next process at the position indicated by the two-dot chain line by the drive unit partially shown in FIG. . Table lifter 3 is used every time separated quantitative paper P' is processed.
increases, and the surface level of the printing paper P is kept constant.

When it is detected that all the stacked papers on the receiving plate 1' have been processed by pressing the limit switch 6 on the receiving plate 1' (or when it is detected by a photoelectric switch (not shown)), as shown in FIG. As shown in FIG. Hold him and lift him slightly upwards. The holding device is driven by an air cylinder. The transfer table 5 holding the receiving plate 1' moves from the station position shown in FIG. 1 to the station position. FIG. 5 shows the receiving plate receiving device which receives the receiving plate 1' when the transfer table 5 is brought into the above-mentioned position, which device comprises the air cylinders 8, 8 and the rods 9, 9 which are raised and lowered by the air cylinders. and a support plate 10 provided above the air cylinders 8, 8, one end of which is raised and lowered by the air cylinder 11 provided on the support plate, and the other end supported by a rotating support 12, and the rods 9, 9 are slanted or with a hole 13 passing through;
Receiving plate 14 receiving horizontal receiving plate 1'
It consists of

In the receiving plate receiving device, when the transfer table 5 holding the receiving plate 1' comes to a predetermined position, the air cylinders 8, 8 are activated, the rods 9, 9 rise until they lightly touch the receiving plate 1', and then The receiving plate holding device 7 releases the receiving plate 1' and retracts to the lateral position.
Next, the air cylinders 8, 8 are activated, and the rods 9, 9 descend with the receiving plate 1' placed on their upper ends, reaching the state shown in FIG. When the state in Figure 6 is reached,
The air cylinder 11 operates to tilt the receiving plate 14 (FIG. 7). When the inclination of the receiving plate becomes large, the receiving plate 1' on top of the receiving plate starts to slide out and falls into the receiving plate storage section 15. The receiving plate storage part is the side plate 16,1
7 and bolts 18 for adjusting the position of the side plate 17 according to the size of the receiving plate.

Once the removal of the receiving plate 1' is completed, the eighth
A suction tool 20 of the frame plate removal means 19 shown in the figure is made to protrude toward the frame board 2, and the frame board 2 is sucked to the suction tool. This suction tool 20 is an air suction pad when the frame plate 2 is made of wood or non-magnetic material, and
When the material is a magnetic material such as a steel plate or iron plate, an air suction pad or a magnet is used.

Once the suction device 20 has suctioned the frame plate 2, it moves backward (FIG. 9), turns off the electricity to the vacuum or magnet of the suction pad, drops the frame plate 2, and stores it in the frame plate storage box 21. Note that the falling impact may be reduced by the rotating belt 22 provided at an angle above the storage box, and then the storage box may be stored.

After processing the boarded printing paper, receiving plate, and frame board of one stage as described above, the next stage of boarded printing paper is processed by the table lifter in the same order as above. Process. When a certain amount of receiving plates are accumulated in the receiving plate storage part 15, they are carried to the required place by a forklift, and when the frame plates are accumulated in the frame plate storage box, the boxes are transported in the same manner.

(Effects of the invention) According to the invention, it is possible to automate all of the separation of printed paper that has been cut out and stacked in multiple stages, stacking, processing of receiving plates, and processing of frame plates, and also the separation and movement of printed paper. The transfer table used for this process can also be used for processing receiving plates, and although it is an extremely simple device, it can greatly improve work efficiency.
