Description

[Detailed Description of the Invention] The present invention relates to an improvement of a board removal device for a sheet-fed printing press.

A conventional sheet-fed printing press's board-taking device is explained with reference to Figs. 1 to 8. In Figs. 1 and 2, 1 is a board-taking board, and 2 is a guide rail, one on each of the operation side and drive side. In FIGS. 4 and 5, reference numeral 13 indicates a frame of the board cutting device, and reference numeral 4 indicates bearings fixed to the frame 13. As shown in FIG. 2, there are two bearings 4 on the outside of each guide rail 2. Also, the fourth
5 and 6 In Figures 5 and 6, reference numeral 5 indicates four levers supported horizontally by the bearings 4, and reference numeral 3 indicates a guide rail receiver attached to the tip of each lever 5. The guide rails 2 are fixed on each guide rail receiver 3, and their openings face each other. In addition, 11 in Figures 2, 7, and 8 is a fixed beam of the board removal device, 6 is a stopper for the board 2 provided on the fixed beam 11, 7 is a handle provided on the guide rail 2, and 7 is a handle provided on the guide rail 2. 2 and 8. 9 in Figures 8 is a rotating plate rotatably attached to the fixed beam 11, 8, 10
1 is a link connecting the lever 5 on the operation side and the driving side and the rotating plate 9, 12 in FIG. 1 is a sheet discharge pile stand, 12a is a sheet discharge pile table lifting chain, and 12b
is a spacing plate, and when performing a planking operation, insert the planking board 1 from one end of the guide rails 2, 2 (the left end in Fig. 2) into the guide rails 2, 2 near the same end, and remove the same planking board. 1 to each of the guide rails 2, and then press the push button switch for fixed quantity lowering provided on the control panel (not shown) to activate the timer, lower the paper discharge pile table 12 fixedly, and then lower the paper stack 12 by a fixed quantity. 12b and a sheet-fed printing machine (not shown)
Insert the above board 1 into the guide rails 2, 2 to the depths of the guide rails 2, 2 at the timing of the fall of the printing paper A (see arrow a in Figure 1). When the printing paper A has accumulated, the spacer plate 1
2b at the four corners of the second board 1 from the top, and then press the lift push button switch provided on the control panel to raise the paper discharge pile stand 12 and the multi-tiered board 1 above it. Then, each of the spacer plates 12b
is brought into contact with the cutout plate 1 on the guide rail side, and then the handle 7 is pulled in the direction of the arrow in FIGS. It is removed from the rails 2, 2 and placed on each of the spacer plates 12b, and then the paper discharge pile table 12 is lowered again in accordance with the amount of printed paper A accumulated.

In the cutting device of the sheet-fed printing press, the cutting board 1
, press the lowering push button switch provided on the control panel to lower the discharge pile table 12 a certain amount to enable installation of the spacing plate 12b, and also
2b is installed, press the raising push button switch provided on the control panel to raise the paper discharge pile stand 12.
It is necessary to bring the spacing plate 12b into contact with the cutout plate 1 on the guide rails 2, 2 side, and in addition to pulling the handle 7, it is necessary to press each of the switches described above, making it difficult to install the cutout plate 1 in one step. There was a problem that it could not be done by human workers.

This proposal addresses the above-mentioned problem, and when the board is inserted from one end of the guide rail into the guide rail near the same end, a descending start command is sent to the elevating drive device on the paper output pile stand. A first limit switch, a second limit switch that sends a descending stop command to the elevating drive device on the paper discharge pile stand when the stripping plate is inserted deep into the guide rail, and a second limit switch that prevents the stripping plate from descending A rise command device such as a timer that sends a fixed rise command to the elevating drive device on the paper discharge pile table when the paper discharge pile table is stopped;
The above-mentioned limit switches are provided on the guide rails of a sheet-fed printing press, and the purpose thereof is to provide an improved sheet-fed printing machine that allows a single operator to install the sheet-fed printing press. The purpose of this invention is to provide a board cutting device for a printing press.

Next, the board removal device of the sheet-fed printing press of the present invention was installed in the 9th and 1st sections.
To explain with an example shown in Figure 0, 1 to 10
is the same part as above, and 14 is the part that is activated by the board 1 when the board 1 is inserted from one end of the guide rails 2, 2 into the guide rails 2, 2 near the same end to create a discharge pile. A first limit switch 15 sends a descending start command to a motor (not shown) for raising and lowering the platform 12.
This is a second limit switch which is activated by the removal plate 1 when the sheet is inserted all the way to the back and sends a descending stop command to the elevating motor of the paper ejection pile table 12.

The board cutting device of the sheet-fed printing press of the present invention is configured as described above, and the board cutting board 1 is moved from one end of the guide rails 2, 2 to the guide rail 2 near the peripheral end,
2 and put the board 1 into the guide rails 2, 2, the first limit switch 14 is actuated by the board 1, and a descending start command is issued to the paper discharge pile stand 12. The sheet is sent to the lifting motor, and the sheet discharge pile table 12 begins to descend. Furthermore, when the paper discharge pile stand 12 is lowered and the spacing plate 12b can be installed, the above-mentioned cutting plate 1 is moved to the guide rail 2,
Insert it all the way to 2. At this time, the second limit switch 15 is actuated by the removal plate 1, and a descending stop command is sent to the elevating motor of the paper stack stack 12, so that the descending of the paper stack stack 12 is stopped.
Next, the lifting motor is driven in the upward direction by a timer (not shown) for a set time, or
A counter that counts the number of sheets of printed paper A that has started to accumulate on the board 1 is inched in the upward direction by the number of counts, the paper discharge pile table 12 is raised, and the spacing plate 12b is moved to the plate on the guide rail side. Removing board 1
come into contact with. When this state is reached, pull the handle 7 to move the guide rails 2, 2 outward so that they are separated from each other, remove the board 1 from the guide rails 2, 2, and place it on the spacer plate 12b. Then, the paper discharge pile table 12 is lowered again in accordance with the amount of printed paper A accumulated.

In this way, in the sheet-fed printing press board removal device of the present invention, the first limit switch 14 is actuated to lower the paper ejection pile stand 12, and the second limit switch 15 is actuated to stop the ejection pile stand 12 from descending. Since the lifting and lifting operations are performed respectively, the push-button switch operation required in the past can be dispensed with, and the cutting board can be installed by one worker.
