Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a sheet conveyance device from a sheet-fed printing press to a folding machine, which consistently performs printing and folding of sheets.

The present applicant has previously developed and proposed a sheet conveying device consisting of an auxiliary table and a take-out table that connects a sheet-fed printing press and a folding machine. , a large number of sheet pressing rollers (hereinafter referred to as rollers) are arranged on these tapes.

) constitutes the conveyance path, so the sheets passing through this conveyance path do not move in a constant posture due to the direction of the rollers, contact pressure, etc., and wrinkles often occur, so these should be prevented. It was extremely difficult to adjust the rollers.

Therefore, a side guide is provided on one side of the conveyance path, and a single conveyance tape is provided near the side guide in the conveyance path and is arranged at an angle so that the forward direction of the conveyance path approaches the side guide. A take-out paper sheet that was designed to be placed and held was considered, but although this device slightly improved the movement posture of the sheet, it was not sufficient and the occurrence of wrinkles could not be prevented.

This invention was made to eliminate the above-mentioned drawbacks.
A side guide is provided on one side of the conveyance path, and a conveyance tape is arranged at an angle near the side guide side in the conveyance path so that the front side of the conveyance path is closer to the side guide, and the conveyance tape is placed on the opposite side of the conveyance path. The balls are placed and held on both transport tapes with a plate, and the frictional force between the sheets of paper on both transport tapes is adjusted by changing the steel balls and plastic balls and their quantity. The present invention aims to provide a conveyance device that moves paper along side guides while generating a slight tension in its width direction, stabilizes the conveyance posture, and does not cause wrinkles.

Hereinafter, the embodiment will be explained with reference to the drawings. In the drawings, 1 is a paper feeding device, 2 is a printing unit, and 3 is a paper discharge unit.

Reference numeral 4 denotes a paper ejection chest built in the paper ejection unit 3, and an auxiliary table 5 is disposed below the sheet ejection part of the paper ejection chest 74.

Reference numeral 6 denotes a take-out table; one end of the table 6 is placed on the discharge side of the auxiliary table 5, and the other end is attached to the folding machine 7.

The take-out table 6 will be explained in detail below. Reference numeral 8.8' denotes a side frame of the take-out chiffle, and both side frames 8, 8' are connected by an upper horizontal frame 9 and a lower horizontal frame 10 that cross the conveyance path.

An upper paper holder 11 is clamped to the upper horizontal frame 9 by a spring member 12, and is suspended so that it can be attached and detached and its position can be adjusted in the lateral direction.

A lower paper tray 13 is provided opposite to and below the upper paper tray 9.

The paper receiving surface of this lower paper receiver 13 is a conveying tape 16 which will be described later.
．． Using a large number of leaf springs that are on the same level as the paper feeding surface of 16' and bent in the paper feeding direction, their sides are connected with rivets 15 and held on the lower horizontal frame 10 so that the width can be changed. There is.

16. 16' is a sheet transport tape that is wound around a roll on a shaft 17 that is linked to the drive device in the folding machine 7 and a roll on a shaft 18 that is installed horizontally at the free end of the take-out table. It rotates in a tilted state parallel to each other in plan view so that the further forward in the road direction (folding machine side) the side guide 19 side is located.

20 is a steel or plastic ball, 21 is a plate that holds the ball 20 on the conveying tape 16 (16'), and the plate 21 (21') is attached to the tape receiver 22 (
22') along the lower horizontal frame 10 so that the position can be changed and fixed, and the conveyor tape and roll can be repositioned with respect to the center of the conveyance path and adjusted in accordance with the size of the sheets to be conveyed. We are making it possible to do so.

24 is a bypass plate.

Since the present invention is configured in this way, the printing unit 2
, the sheet 25 is conveyed to the folding machine 7 side via the paper discharge unit 3 and the auxiliary table 5. On the take-out table 6, the upper surface is pressed by a ball by a conveying tape that rotates with both sides tilted parallel to each other. However, the poles that press the paper on both tapes use an appropriate number of steel balls or plastic balls so that the frictional force of the side guide side conveying tape 16 is slightly greater than the frictional force of the other conveying tape 16'. By adjusting the height, the sheets can be fed to the folding machine in a stretched state and with the posture regulated by the side guides.

Therefore, the sheets fed to the folding machine in this manner will not be folded in a wrinkled state or folded diagonally.

Note that in the above embodiment, the opposite side guide side conveyor tape is arranged parallel to the side guide side conveyor tape, which is disposed so as to be located closer to the side guide toward the front in the direction of the conveyance path. It may be arranged in a vertical shape.

As described above, according to the present invention, printed sheets can be fed to the folding machine in a stretched state and in a constant posture regardless of the width of the paper, and the integrated printing and folding operations can be performed by improving the folding performance. It has a dog effect that can significantly improve efficiency.
