Description

[Detailed Description of the Invention] The present invention relates to a pile transfer device used in a sheet pile transfer process that involves reversal such as reverse printing in sheet printing operations.

The handling of sheets in a sheet-fed printing press occupies a considerable part of the printing operation.

Handling of the sheets includes 1) stacking for first printing, 2) reversing, drafting, and transshipping for reverse printing, and 3) drafting and transshipping for second and third passes. Among these processes, pile reversing machines have traditionally existed as equipment used in the reversing, drafting, and reloading processes for back printing, that is, the reloading process of sheet piles that involves reversing. ing.

The outline of this pile reversing machine will be explained with reference to FIGS. 1a to 1C as well as how it is used. When the rectangle of the reversing machine main body 1, which is a rectangular notch in a part of a cylinder, forms a vertical surface (Fig. 1a) ) A sheet pile 2 made of stacked sheets is inserted into the reversing machine main body 1, clamped with a presser plate 3, and then rotated in the direction of the arrow in the figure by driving the rotating roller 4.

During this rotation, as shown in Figure 1, the air inlet nozzle 5 is moved from the lower end of the sheet pile 2 to the upper end and vibrations are applied to move the sheets up and down to air in. .

Subsequently, as shown in FIG. 1C, the reversing machine main body 1 is
The rotating roller 4 is stopped in the state of rotation by 0°, and the presser plate 3 is
After removing the sheet pile 2, the sheet pile 2 which has been reversed is taken out of the reversing machine main body 1.

However, in such a conventional pile reversing machine, when the paper surface of the sheet is horizontal or in a state close to this, when the above-mentioned air blowing is performed, the sheets at the lower end of the sheet pile 2 are unbalanced due to the weight of the paper itself. Since the paper is pressed, it is difficult for wind to enter.

In order to avoid this, the winding is performed when the paper surface of the sheet is nearly vertical as shown in FIG. 1(b), but at this time, the sheet is It is necessary to support pile 2.

However, due to the general characteristic of sheet paper, which is its weakness,
It is not only difficult to support the sheets so that they do not buckle and allow wind to easily enter the sheet pile 2, but also when the sheets protrude from the ends of the sheet pile 2. When the above-mentioned movement of the air intake nozzle 5 occurs due to the air intake operation, the protruding sheet is bent by the air intake nozzle 5, thereby closing the gap between the sheets. Therefore, it becomes impossible to ventilate this part.

In addition, in order to prevent bleed-through between the sheets in the printing work, a pile stand 6 with a plurality of boarded boards is formed as shown in Figures 2 and C, and the pile stand 6 is distributed in each step. The sheets are stacked to form a sheet pile 2. However, when the sheet pile 2 is reversed using the prior art pile reversing machine as described above, the sheet pile 2 is stacked as shown in FIG. As shown in a, it is necessary to re-form the sheet pile 2 so that the sheets are piled up in a bar.

In view of the various problems of such conventional pile reversing machines, the present invention provides a pile reloading device that eliminates these problems and is useful in a sheet pile reloading process that involves reversing. Its structure consists of a drum whose journal portion is rotatably supported by a drive source between at least two parallel frames, and a roller rotatably supported between the frames. and an endless track-shaped inner tape suspended between the drum and the inner tape, which are located on the same side with respect to the vertical center line of the drum, and on the same side as the roller suspending the inner tape, and further with relative A sheet of paper is suspended between the drum and at least two rollers that have a vertical relationship and are rotatably supported between the frames, and are suspended outside the inner tape and hold the sheet between the drum and the drum. an endless track-shaped outer tape which can be clamped and reversed as the drum rotates, and which is driven at the same or slower speed than the inner belt, and the sheets are fed onto the outer tape; a sheet feeding device for transporting the sheet, a conveying device for unloading the sheet after it has been reversed, an air blowing nozzle disposed at the unloading end for blowing air from below and behind the sheet, It is characterized by having a guide plate that guides the falling sheets, and a pile stand on which the fallen sheets are placed and stacked.

7b, and supports rollers 28, 29, and 30 via bearings (not shown) fitted into the side plates 27a and 27b, respectively.

A tape 31 in the form of an endless track is suspended between the rollers 28, 29, 30, and the roller 17, alternating with the inner tape 19, and forms a conveyance section for sheets after the reversal is completed.

Tension of the tape 31 is given by suspending the tape 31 on a tension pulley 33.

That is, the bearing portion 33a of the tension pulley 33 is fitted into the guide rod 32 installed downward in the block 27, so that the weight of the tension pulley 33 directly acts on the tape 31 as tension.

Further, an air inlet nozzle 34 is attached to the end of the block 27 on the left side of the roller 28 in parallel with the roller 28, and airs the sheet carried out with the tape 31, and also blows air into the block 27. By adjusting the position of 27, the line on the left end side of the air hole nozzle 34, which is perpendicular to the frame 10 and facing the delivery pile 52, can be made to correspond to the size of the sheet.

As shown in an enlarged view in FIG. 8, this air hole nozzle 34 has a plurality of holes 34b formed on the circumferential surface of the air hole nozzle 34 through which air is supplied from a blower (not shown) through a supply port 34a.

A support 42 and a support 4 are installed inside the delivery frame 37 at right angles to the delivery frame 37.
2a, and a parallel guide rod 43 is attached to the delivery frame 37 via the support 42 and the support 42a.

Further, a plurality of vertical guide plates 44 (two in the figure) are attached to the guide rod 43 to determine the end of the delivery pile 52 on the frame 10 side, and are shown in FIG. 6 together with the guide plates 41. The pile table 45 is inclined as shown in FIG.

The vertical movement of the pile stand 45 is achieved by engaging the pile stand 45 with a hanging device 46 similar to the pile hanging device in the delivery of a conventional printing press and driving the motor 46a of the pile hanging device 46. It is now done by

Further, an upper surface detection device 48 fitted to the pile 38 is connected to the pile hanging device 46, and after the surface of the delivery pile 52 is maintained at a predetermined height, several surfaces of the delivery pile 52 are It is meant to be held in place.

Reference numeral 49 denotes a plurality of (two in the figure) air hole nozzles for blowing air holes into sheets from the upper side of the delivery pile 36, and this part is shown in an enlarged view in FIG. This is similar to the nozzle 34.

Further, the position of the air hole nozzle 49 in the horizontal direction in the figure is determined by fitting it to a rod 50 parallel to the frame 10a, and the rod 50 is fitted to a support 51 fitted to the kattle 38. By doing so, the position in the vertical direction is determined.

Note that the sheet feeding device 14 in this embodiment uses the head 14b of a conventionally known automatic sheet feeder, but unlike the automatic sheet feeder, the sheet feeder 14 accurately shifts the sheets by a fixed amount and one by one. There is no need to send it.

In short, the amount by which the sheets are shifted in this case may be irregular, as long as the sheets do not become bulky in the drum 12 area.

Therefore, when sending out sheets, for example, a suction roller may be used in addition to the head 14b, or the upper surface of the sheet pile 2 may be tilted and air can be blown to send out the sheets.

Further, the sheet pile 2 is suspended from a hanging device 14c so as to adjust its vertical position and hold the top surface of the sheet pile 2 at approximately the same height as the outer tape 18.

To explain in detail the operation of the device of this embodiment along with its usage mode, the sheets are fed through the delivery port 1 of the sheet feeding device 14.
4a and is continuously supplied onto the outer tape 18 while being shifted by a certain amount.

Further, the sheet is sandwiched between the outer tape 18 and the inner tape 19, rotates approximately half a turn on the outer circumference of the drum 12, and is conveyed to the tape 31 by passing between the rollers 16 and 17 in a completely reversed state. The air is vented by the action of the vent nozzle 34, and falls onto the pile stand 45, and the delivery pile 5
2 will be formed.

During this process, when a sheet of paper rotates around the outer periphery of the drum 12, the sheet is turned over by the half-rotation, and at the same time, the sheets that are attached to each other due to ink or the like are coated with a difference in paper thickness. Due to the difference in rotation radius and the speed difference between the inner tape 19 and the outer tape 18, a shifting force is exerted, and the tape 31 is carried out to the next tape 31 in a continuously shifted state.

Further, when the sheets fall from the air hole nozzle 34 and form the delivery pile 52, air is blown sufficiently between the sheets by the air inlet nozzle 34 and the air inlet nozzle 49, and the air is blown between the sheets. reduce friction.

This reduction in friction, together with the inclination of the guide plates 41 and 44, causes the sheets to align against the guide plates 41 and 44.

When the sheets have formed a delivery pile 52 of a predetermined height, the upper surface detection device 48 detects this and lowers the hanging device 46 to maintain the uppermost surface of the delivery pile 52 at approximately the predetermined height.

When the delivery pile 52 is completed in this manner, the motor 47 is rotated to rotate the support shaft 36 to form the state shown by the chain line in FIG. 3, that is, the state where the guide plate 44 is vertical.

At this time, as shown in FIG. 6, the slope with respect to the guide plate 41 remains, but by lowering the delivery pile 52 onto a horizontal platform such as a trolley, the delivery pile 52 becomes a normal stacked state as shown by the chain line in FIG. .

As specifically explained above in conjunction with the embodiments, according to the present invention, since the sheet is reversed using the outer circumferential surface of the drum, buckling and damage of the sheet can occur as in the conventional method. The above-mentioned reversing and drafting operations can be carried out without worrying about this, and this is particularly effective for reversing weak thin paper.

In addition, since the air is aired at the top of the delivery pile, sufficient air airing can be performed without being affected by the weight of the paper.

Furthermore, in the reversing step, the radius of rotation differs due to the difference in paper thickness of the sheets, and the speeds of the inner and outer tapes differ, so even if the sheets of paper adhere to each other due to ink or the like, it is difficult to peel them off. can.
