Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and equipment for conveying stacked sheets of paper to a paper feed section of a printing press, and in particular to a method and equipment for conveying stacked sheets of paper to a paper feed section of a printing press, and in particular to a method and equipment for conveying stacked sheets of paper to a paper feed section of a printing press. The present invention relates to a conveying method and equipment for supplying stacked sheets of paper to a paper feed section of a printing machine again for printing.

Conventionally, even though printing machines themselves have been automated, the current situation is that the work of loading printing paper is still handled manually. This work is mainly occupied by reversing work and loading processing work, and as the speed of printing presses increases,
Handling paper in double, four-hole, and Kikuzen formats each weighs 10 tons per day, making it hard work. In order to alleviate such conditions, individual work processing devices have been proposed.In the inversion work, the paper is turned over in a vertical upright state or in a horizontal reference state, and in some cases, it is oscillated in a horizontal reference state. Some machines also serve as paper handling by blowing air, but the weight of the paper is applied properly, damaging not only the paper but also the print image, making it uneven, etc.
Moreover, there is a possibility that paper separation may become worse due to the weight of the paper. In addition, the loading process is normally carried out by driving a fork truck on-board, but it is difficult to accurately and easily move the stack of paper back and forth and left and right to match the paper feed section of the printing machine. It is necessary to transfer the paper to a special vehicle for position adjustment that has alignment rulers and side edge alignment rulers, and the loading status of the paper must be checked each time.

Therefore, the present invention provides a reversal transfer section and a reversing transition section when feeding the stacked sheets back to the paper feed section of the printing press in order to print on the blank side of the back side of the single-sided printed sheets stacked in the wandering section of the printing press. By connecting the floor loading moving unit near the paper feed unit of the printing machine, the front and back edges and left and right edges of the stacked single-sided printed paper are aligned, the front and back sides of the paper are changed, and the paper is used to align the top and bottom of both sides of the printing. By changing the front and back of the paper and adjusting the position of the stacked paper in order to match it with the paper feed section, we have adopted a process in the conveyance flow to dramatically improve manual overvoltage labor. An object of the present invention is to provide a transportation method and equipment that can quickly, accurately, and easily carry out the following steps.

In the present invention, in the reversal transition section, the printing paper is pinched with appropriate pressure by both the upper and lower forks, tilted at 45 degrees, and then rotated through 180 degrees. In this way, while maintaining the optimal balance of the center of gravity for the weight of the paper, it is possible to reverse the paper in a narrow space by remote control on the vehicle body, and to keep the paper well aligned to the next floor loading transfer section. Transfer can be made smoothly.

Further, according to the present invention, the floor loading moving section smoothly smooths the leading and trailing edges of the printing paper using a turntable mechanism provided on the floor and a lifting/lowering loss conveyor mechanism disposed above the turntable. To provide a conveyance method and its equipment that can be converted into a paper feed section and accurately and easily adjust the position to match the paper feed section of a printing machine.

Embodiments of the present invention that achieve these objects will be described in detail with reference to the drawings.

FIG. 1 is a route diagram illustrating a method for conveying stacked sheets from a sheet discharge section to a sheet feed section in a printing machine according to the present invention.

Reference numeral 1 denotes a printing machine, and 2 is a paper discharge section thereof.A pair of discharge receivers at a station for receiving printed paper 3 are provided with rods 4.
4” and chains supporting those bars 4.4” 5.5
It is designed to move up and down depending on the amount of paper stacked. The printed sheets 3 are neatly stacked on a pallet 6 placed horizontally on a bar 4.4'', and at the end of the printing job they are lowered together with the pallet 6 onto a roll conveyor 7 placed on the floor directly below. placed on top. 3a shows the leading edge of the printed paper, and 3b shows its surface. The paper 3 is transferred together with the pallet 6 via a conveyor 9 onto a cart 8. When the printed paper 3 is printed on both sides, it is stored as is, but when it is printed on one side, it must be conveyed to the paper feed section 10 again. The present invention relates to a transport method and equipment for this process.

Symbol A is single-sided printed paper 3 loaded on the paper output section of the printing machine.
This is a transition process in which the vehicle is placed on the reversing vehicle 11, and is indicated by a bag arrow. In the transition process A, the single-sided printed paper 3'' is transferred to the trolley 8.

The paper bundles are stacked piecewise with the printing screen facing upward through the angle, along side edge aligning rods 14 fixed to the side of the reversing board, with the front edges of the sheets pushed inward. During this work, the above-mentioned reversing transfer vehicle may be used instead of a trolley to immediately transfer the paper, but there is a need to place a suitable vehicle between the paper discharge section and the paper feed section of the printing machine for the purpose of security. It is necessary to provide sufficient space, and if paper is handled on the transfer vehicle, there is a risk of damaging the important printing surface and paper due to the weight of the paper itself. It is more effective to move the paper bundle together with the reversing transfer wheel at the same time, as appropriate pressure relief and appropriate space formation for accelerating drying can be achieved at the same time, for paper handling.

The printing paper 3'' placed on the reversing transfer wheel 11 is moved between both pallets 6', 6 by lowering the upper stage fork 15 provided on the reversing plate 12, which is movable up and down, in the direction shown by arrow a. ” caught in between. Reversing board 1

In this holding mode, the weight of the single-sided printed paper 3 is optimally applied, so that the printed image on the paper is not damaged by slipping, and the leading edge of the paper is properly aligned with the surface of the reversing plate 12. It can be kept aligned.

The single-sided printed paper 3' loaded on the reversing transfer vehicle at an angle is moved to the side edge of the paper when looking at the reversing transfer vehicle 11 from the side of the stacked paper as shown by the bag arrow C (capital letter C) by operating the command unit 21. It is reversed by rotating the base plate 19 by half a turn around its central axis in the direction shown by arrow C (lower case C) so that the alignment rod 14 is on the lower side. That is, print screen 3'
b comes downward, and the back side of the blank paper newly appears on the top side.
