Description

[Detailed description of the invention] This invention prevents paper turning in an automatic collating machine that regularly and automatically feeds and stacks the required number of sheets in sequence before binding a set of slips made of several sheets of paper. It is related to the device.

Paper feed racks are arranged in a horizontal row at equal intervals, and the top sheets of paper stacked on each sheet feed rack are taken out at the same time and transferred onto the plywood in front, where each sheet taken out is placed on the plywood board. Cross-feeding involves intermittently repeating an operation in which the head edge of each paper is held in place while being swept upwards, and then each paper is then transversely-feeded a certain distance (corresponding to the pitch of the paper feed mount) in one motion. In a type automatic collating machine, the head end of each paper is held by a clamp, so it will not be fanned during cross-feeding, but the tail, or free end, may be agitated due to wind pressure or the curl of the paper itself. Turning will occur and stable collation will be hindered.

This phenomenon is subtly influenced by paper quality, size, machine operating speed, etc.

The present invention solves the above problems using a simple method, and will be described below based on one embodiment thereof.

That is, FIG. 1 is a vertical side view of a horizontal feed type automatic collating machine in which the present invention is implemented.Although not shown on the left side of the drawing, paper feed racks are arranged in a horizontal row at equal intervals, and each The required paper to be supplied is loaded on the paper.

By the way, 1 is a paper take-out machine, and is provided with a running body 3 that slides along parallel rails 2 installed on the left and right sides of the machine, and a beam 4 that connects the two runs across this running body 3. A paper holding claw 5 is provided on this beam member 4.

Then, when the paper take-out machine 1 approaches the paper feed stand and holds the uppermost sheet of paper with its paper holding claws 5, it moves inverted again and stops at the position shown in FIG. 1, where the base plate 6 The upward paper take-out operation is completed.

Note that the reciprocating motion of the paper take-out machine 1 can be provided by incorporating a crank mechanism and connecting this to the traveling body 3.

The paper A taken out onto the base plate 6 is released from the paper clamp claw 5 by the operation of the knock-down tool 7, and its head edge is placed on the belt 9 of the paper transverse feeder 8, respectively.

It should be noted that after discarding the paper, the discharging tool 7 immediately rotates to the upper position and assumes the next operation mode, and the paper take-out machine starts the next paper take-out operation.

Next, the paper transverse feeder 8 starts operating, but at this time, the clamping body 11 provided on the operating plate 10 falls down, presses the head edge of the paper with its tip, and passes the paper through the belt 9. Actuation plate 1
0, the actuating plate 10 is moved horizontally a certain distance, and when this horizontal movement is completed, the paper is held between the clamping body 1
1 is lifted up, the clamp is released, and the actuating plate 10 is returned to its original position.

Note that the movement of the belt 9 is provided only by the feeding operation of the actuating plate 10, and the reciprocating movement of the actuating plate 10 can be provided by the movement of a crank mechanism (not shown) via a lever interlocked therewith.

In the figure, 12 is a guide rail, 13 is a roller that holds the guide rail, and 14 is a support leg that supports the actuating plate 10.

As explained above, the present invention prevents the turning of paper in a horizontal-feeding collating machine that intermittently repeats the operation of picking up sheets of paper by the head edge and feeding them a certain distance in the horizontal direction. The purpose is to bend the rear half of the free end of paper A upward in a horizontal straight line, thereby giving it stiffness to resist wind pressure.

In other words, 15 shown in FIG. 1 is a certain stiffening strip made of angle material placed at a suitable place on the plywood 6, and its position is changed as appropriate depending on the size of the paper. It is installed parallel to the edge of 6.

Due to the presence of the stiffening strip 15, the paper A taken out here is partially lifted upward and this section is bent, and the shape of the bending section provides rigidity to the free end A' of the paper. In other words, waist is given.

FIG. 2 shows that a protruding piece 16 is provided on the above-mentioned buckling strip 15, which is inserted into a long hole 17 provided in the base plate 6, and its position can be freely adjusted by sliding the buckling strip 15. This example shows an example of using plywood 6 as shown in Figure 3 depending on the situation.
It may be oval-shaped and have the stiffening strips 15 protruding from the appropriate locations.

According to the present invention, in a horizontal feed type automatic collating machine, the plywood that supports the taken out paper is provided with a fastening strip at an appropriate position, and the paper is clamped at the head edge and transferred in one direction. Regardless of the size of the paper being used, the bending part is placed at an appropriate position on the free end of the rear half, and this adds rigidity, or stiffness, so it is possible to prevent curling due to wind pressure and curling of the paper, which occurs especially when the paper is thin. This automatically corrects the curl caused by the paper and greatly contributes to achieving smooth and reliable collation.

By implementing the present invention, it is possible to increase the operating speed (rotation speed) of the machine, thereby making it possible to improve efficiency.
