Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a temporary holder used for inserting plates at appropriate intervals between stacked printing sheets in a paper discharge section of a two-sheet printing machine. This invention relates to a guide device.

[Conventional technology]

In a sheet-fed printing machine that feeds printing paper one by one from the paper feed section, prints it in the printing section, and discharges the printed paper to the ejection section and stacks it one after another, as shown in Figure 9, In order to prevent set-off (a phenomenon in which the ink on the top surface of the paper adheres to the paper stacked on top of it) that occurs when sheets of paper l are stacked on the pallet 2, a temporary (slatted board) 3 is placed at intervals of a certain number of sheets.
is inserted, and the plate 3 is supported by the support 4, and the plate 3 is
Paper 1 is stacked on top.

Fig. 1O schematically shows a paper discharge section 5 of a conventional sheet-fed stamp sorting machine. a chain 7 connected to a lifting mechanism (not shown) that raises and lowers the chain 6;
It has a pair of board insertion guides 8 and the like for inserting the board 3 into a predetermined board insertion position above the lifting bail 6. As shown in FIG. 11, the pair of board inserting guides 8 are arranged in parallel so as to face each other across a predetermined board inserting position, and are manually operated by operating a control lever (not shown). As a result, it is configured to move between the position indicated by the actual i48 and the position indicated by the two-dot chain line 8'. Further, a board insertion limit switch 9 is provided at the front end of the board insertion guide 8.

The temporary loading operation in the conventional sheet discharge section 5 having the above configuration is performed as follows. In FIG. 1O, normally, as printing sheets 1 are stacked on the lifting pile 6, the lifting pile 6 is automatically lowered so that the top surface of the stacked sheets is at a fixed position. After doing the previous board insertion.

When the number of sheets accumulated on the board approaches a certain number, the operator 9 moves the board inserting guide 8 to the closed position shown by the solid line in Figure 11, carries the board 3 to the board inserting guide 8, and inserts the tip of the board into the closed position. Place it on the tip of the board inserting guide 8 (see Fig. 10).As a result, the board inserting limit switch 9 provided at the tip of the board inserting guide 8 is activated, and the lifting pile 6 is lowered by a certain amount. The top of the stacked sheets of paper l is at a lower position than the inserting guide 8.0 The operator checks f! that there are no obstacles in the inserting position. After acknowledging it.

The board 3 is slid on the board inserting guide 8 and inserted into a predetermined board inserting position (see Fig. 12).Then, as shown in Fig. Board 3
The 0th order manually supplies the struts 4 to the four locations on the top.

Raise the lifting pile 6 and stop it at the position where the upper end of the support column 4 almost touches the bottom surface of the plate 3 held by the plate insertion guide 8 (see Fig. 13), and then the operator should move the plate 3 directly below it. After visually confirming that it can be supported by the support column 4, operate the operation lever (not shown) to remove the temporary insertion guide 8.
The plate 3 is now supported by the supporting column 4 below. After this,
The elevating pile 8 automatically descends so that the top surface of the stacked sheets is always at a constant position, and one loading operation ends when the stack reaches 0 or more.

[Problem to be solved by the invention]

However, in the conventional board insertion work described above, as shown in FIG. It is necessary to wait for the paper to descend to a certain point, and then insert the plate at the timing of paper ejection.

There was a problem that not only did it require skill, but it was also double labor.

The board insertion work needs to be done once every 3 to 5 minutes.

This places a heavy burden on workers, and there is currently a desire to mechanize this board insertion work. A method for automating board insertion is to install a guide that guides the board at the extended position of the FX insertion guide, have the guide hold the board, and push the board in with an air cylinder, or to stack the board in front of the board insertion guide. A possible method is to provide a board that can be moved up and down, place the top board at the same height as the board insertion guide, and then push that board into the board insertion guide using an air cylinder or the like.

However, in these methods, adjacent to the paper ejection section,
It is necessary to provide equipment such as a guide to guide the board, a lifting mechanism to adjust the board to the same height as the board insertion guide, and an air cylinder to push the board, which takes up a considerable amount of space.

There is a risk that various operations around the paper ejection section (support supply operations, paper removal operations, etc.) may be hindered. Furthermore, if it is attempted to automate the pillar supply work, etc., there will be a problem that there will be no place to install the pillar supply device.

The present invention has been made in view of these problems.

To provide a board insertion guide device capable of automatically inserting a board without taking up much space around a paper discharge part.

[Means to solve the problem]

The present invention includes a pair of guide outer frames arranged on both sides of a board insertion position in a paper discharge section of a two-sheet printing machine, and a telescopic guide that is extendably held in each guide outer frame and holds one end of a board to be inserted. and the pair of guide outer frames. The gist of the present invention is a board insertion guide device for a paper discharge section of a sheet-fed printing press, which has a guide opening/closing device that moves the two in the direction toward each other and vice versa.

[Effect]

In the sheet insertion guide device with the above configuration, 1. Normally (during normal paper stacking without sheet insertion), the guide extension and contraction part is retracted within the guide outer frame, and there are almost no parts protruding outside the paper ejection section. Workers working around the paper department.

When performing zero-order board insertion that does not impede walking, etc., the guide telescoping device extends the guide telescoping section to the front of the guide outer frame, thereby extending the guide telescoping section to the outside of the paper ejection section. The board holder can be placed in the holding position, and the board can be placed and held on the guide telescopic part without interfering with the accumulation of paper on the elevating pile. In this state, after the lifting pile is lowered, the guide expansion and contraction device contracts the guide expansion and contraction part into the guide outer frame at a predetermined timing, so that vi can be inserted into a predetermined boarding position above the lifting pile. . In addition, when the lifting pile subsequently rises and the guide opening/closing device opens the pair of guide outer frames with the board supported by the pillars on the lifting pile, the pair of guide telescoping parts holding both ends of the board come out. You can move the plate towards the side to release the plate and hold the plate to the support.

In this way, the plate 3 is inserted into the predetermined temporary insertion position. Thereafter, by opening the guide outer frame 22 to the position indicated by the two-dot chain line in FIG.

In FIG. 1, the board supply device 18 lifts the board 3 from the temporary storage area 17 and supplies it onto the guide extension/contraction section 23 extending forward of the board insertion guide device 16. This plate feeding device 18 is not particularly limited, and examples include two devices previously applied by the present applicant (Japanese Patent Application Laid-Open No. 1983-1996).
The detailed mechanism of this device will not be described here, but will be explained using FIGS. 5 and 6.

The board supply device 18 includes a transverse rail 42 extending from the temporary storage area 17 (see FIG. 1) to the vicinity of the paper discharge section 5, and an electric hoist 43 that runs on the transverse rail 42. It also includes a holding plate 46 suspended via a telescopic body 45, a vacuum band 47 attached to the holding plate 46, and the like.

can be supplied above. This board supply device 18 can be used only if the traveling rail 42 can be installed! The feeding route and the temporary storage area can be set freely, and therefore the temporary storage area 17 is installed at a position that does not interfere with various operations of the paper discharge section 5.

In FIG. 1, the prop supply bag 219 for supplying the props 4 onto the lifting pile 6 is not limited to the vF, but is, for example, a device F (Japanese Patent Laid-open No. 62
-215223 [Temporary support automatic supply device for sheet-fed printing press]
) can be used, an external view of which is shown in FIG.

This device includes an arm portion 52 composed of a link mechanism,
It includes an adsorption tool 53 such as an electromagnet held at its tip, a cylinder 54 that expands and contracts the arm portion 52, a cylinder 55 that rotates the arm portion 52 in the horizontal and vertical directions, a support stand 56 on which the support support 4 is placed, and the like. The arm portion 52
is in a vertical state, and in that state, by extending the arm part 52, the suction tool 53 at the tip attracts and holds the pillar 4 on the pillar holder 56, and then the arm part 52 is retracted and rotated to a horizontal state. By again putting the stretching suction device 53 into a non-operating state, it is possible to supply the material onto the plate 3 on the lifting pile with the support 4 in an erected state. Since this device can supply supports 4 at two locations at the same time, it is sufficient to place one each at the front and rear of the lifting pile 6, as shown in FIG.

Next, operations such as board supply, temporary insertion, and column supply by the automatic board insertion apparatus having the above configuration will be explained with reference to FIGS. 8(A) to 8(E). Note that the following operations are sequentially controlled by a control device (not shown).

(A) FIG. 8 (A) shows the board insertion standby state.

That is, the elevating pile 6 is in an automatic lowering state, and as the sheets to be discharged are accumulated, it is gradually lowered so that the top surface of the accumulated sheets 1 is always at a constant position.

The board supply device 18 is on standby in the temporary storage area 17, and the board insertion guide device 16 is in an open state with the two guide outer frames 22 open and the guide telescopic section 23
is in the line state, the arm part 52 of the support supply device 19 is facing downward,
It is in a contracted state.

(b) When the number of sheets printed since the last time of board insertion is counted and the number of sheets printed is close to the preset number, that is, the number of sheets at the board insertion interval.

For example, when you are about 100 sheets short of the set number of sheets.

Start preparing for board insertion.

In the board loading preparation operation, the board feeding device 18 suction-holds the board 3 in the temporary storage area 17 from the state shown in FIG. Transport to. In parallel with this.

The board inserting guide device 16 is in a closed state, the guide telescoping section 23 is extended in front of the paper discharge section 5, and the board 3 can be received and removed from the board supply device 18. The support supply device 19 is in a state in which the arm portion 52 is extended, the suction tool 53 holds the support support 4 stacked on the support stand 56, and the arm portion 52 is contracted.

(c) The board supply device 18 inserts the board 3 into the board insertion guide device 16.
Pass the receiver to the guide telescoping section 23. After confirming that the plate 3 has been placed inside the guide telescoping section 23 using a detector (not shown),
The plate supply device 18 releases the suction and holding of the plate by the vacuum pad 47 and returns to the original position shown in FIG. 1(A). After the plate 3 is securely held by the guide telescoping section 23.

The lifting pile descends a certain amount. At the same time, in the paper discharging section 5, the flow of paper that had been flowing from the paper discharging cylinder 11 to the paper discharging chain 12 is switched to the auxiliary paper discharging chain 13 side.

Paper is temporarily accumulated in the auxiliary paper tray 14 (see FIG. 1).

(d) A detector (not shown) detects when the elevating pile 6 has started to descend by a certain amount and the top surface of the printing paper 1 stacked on the elevating pile 6 is below the inserting position of the inserting guide device 16. f! When the board 3 to be inserted and the printing paper l no longer interfere with each other by taking sufficient timing from the start of descent by a certain amount, the guide extension/contraction part 23 of the board insertion guide device 16 quickly retracts and holds the board. Insert the plate 3 into the predetermined position. Thereafter, the sheets from the sheet discharge cylinder 11 are sent to the sheet discharge chain 12, and are sequentially stacked on the board 3 into which the sheets have just been inserted.

When the elevating pile 6 has finished lowering by a certain amount and the elevating pile 6 has stopped, the support supply device 19 rotates the arm portion 52 that holds the support pillar 4, brings it into a forward facing state, and then lifts the arm portion 52.
is extended, the support 4 is placed on the plate 3 so as to be along the topmost printing paper 1, the arm part 52 is retracted, rotated downward, and waits for the fifth operation.

(E) Next, the elevating pile 6 is transferred to the above-mentioned column supply device 19.
The upper end of the support column 4 supplied in step 4 contacts the lower surface of the plate 3 previously inserted by the plate insertion guide device 16, and is raised until it is slightly lifted. When a detector (not shown) detects that the plate 3 is slightly lifted by the support 4.

The lifting of the lifting pile 6 is stopped, and the board inserting guide device 16
Open. Thereafter, the elevating pile 6 is automatically lowered to a normal paper stacking state. On the other hand, the plate feeding device 1
8 returns to its original predetermined position and waits for the primary operation.

With this, one sheet insertion operation is completed and the state returns to the state shown in FIG. 9 (A). At the time of the 0th sheet insertion, the operations from (A) to (E) are sequentially repeated.

In the above embodiment, the auxiliary paper ejection chain 1 is provided in the paper ejection section 5.
3 and an auxiliary paper tray 14 are provided when inserting the board.

Although the paper is temporarily accumulated in the auxiliary paper receiver 14 and the paper is not ejected onto the elevating pile 6, the paper ejection section 5 is not necessarily limited to this structure. The structure may be such that the paper is ejected from the paper ejection chain 12 onto the elevating pile 6. In this case, the guide telescoping section 23 of the nine-board inserting guide device 16 is activated at a predetermined timing relative to the ejection of the paper from the paper ejection chain 12. By quickly retracting the plate, the board can be inserted through the gap between the sheets of paper falling.

Further, in the above embodiment, the board feeding device 18 supplies the board to the guide expansion/contraction section 23 of the board insertion guide device 16 and supplies the pillars onto the elevating pile. Although this is automated by providing the support support device 19, it is also possible to have a configuration in which these steps are performed manually.In this case as well, the temporary insertion operation can be performed automatically by the board insertion guide device 16, so that the temporary insertion by two workers is possible. The labor required for the work and the purity of P can be significantly reduced.

〔Effect of the invention〕

As explained above, the board inserting guide device of the present invention is as follows:
A guide extensible part is held so as to be expandable and retractable with respect to the guide outer frame arranged on both sides of a predetermined board insertion position, and the guide extensible part is expanded and contracted with respect to the guide outer frame by a guide extensible device, and the guide outer frame is further expanded and contracted. Since it is configured to be opened and closed by a guide opening/closing device, during temporary insertion, the guide extensible portion is extended forward from the guide outer frame.

The guide telescopic part can be a board receiving position located outside the paper discharge part, and after feeding the board thereon.

By retracting the guide telescoping section using the guide telescoping device, the board can be inserted into a predetermined board insertion position.

Thereafter, by opening the guide outer frame with the guide opening/closing device, the plate held by the guide telescoping section can be released.

Therefore, there is no need for temporary insertion work that requires the skill of the operator as in the past, and it is possible to reduce the burden on one operator. In addition, since the guide telescopic section can be retracted into the guide outer frame, it does not protrude to the outside of the paper ejection section.

Therefore, the board inserting guide device of the third aspect of the present invention does not take up much installation space, and has the advantage that it does not interfere with the various tasks and walking of the operator around the paper discharge section.

In addition, the board insertion guide device of the present invention can supply boards from above with the guide telescopic portion extended, so that the board can be fed by the hoist type board supply device 18 as shown in the embodiment. is possible and also.

Since no extra installation space is required, it is possible to install the support supply device 19 in the paper discharge section 9. For this reason.

As shown in the embodiment, a board inserting guide device of the present invention was used.

It is easy to combine with the board supply device and the support column supply device, and with this configuration, board supply, temporary insertion,
All operations related to board insertion, such as supplying pillars, can be automated, making it possible to perform board insertion without two workers. Furthermore, when using the hoist-type board supply device 18, there are virtually no restrictions on the location of the temporary storage area, so the temporary storage area can be freely determined depending on the environment around the printing press and work efficiency.
