Abstract

PURPOSE:To reduce the amount of deflection of the punched-out paper at the paper piling position by installing a releasing means which releases a hook and a brush member at a same time and drops the paper, when the punched-out paper is transferred and laid. CONSTITUTION:A hook 10 holds the front edge of the paper for which punching treatment is completed, and shifts along two-point chain line and releases the holding for the paper, at the hook position. Walls 11 and 12 surround the paper piling position, and a brushing member is constituted of a brush 21 and an iron plate 22 and is used for clipping the rear edge of the paper. When the hook 10 reaches a prescribed position, the brush member releases the paper clipping operation in synchronization with the release of holding of the hook 10, and the paper is dropped. A holding plate 91 holds a bevel gear 71, gear 71a, arm 72, brush 21, iron plate 22, rack 80, gears 81 and 82 directly and indirectly, and each amount of transfer of the brush 21 and the iron plate 22 is adjusted by adjusting the amount of shift of the holding plate 91.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for controlling the stacking positions of punched papers in a paper punching machine.

The following are known as conventional paper stacking position control devices. That is, four walls are provided to surround the paper stacking position, claws are provided to pass over the area surrounded by the walls, and the front edge of the paper is gripped by the claws at the beginning of the movement of the paper. It is known that the grip of the claws is released when the paper reaches the stacking position. By repeating this operation, the sheets of paper are stacked at the same position.

However, when stacking punched papers using the above-mentioned conventional example, there is a problem in that there is a large misalignment between the sheets at the stacking positions. In other words, when a punched paper is gripped by a claw, the claw is moved to feed the paper, and the claw is released at the same position at the end of the stack, the punched paper will be at the edge of the hole created by the punching. Compared to paper that does not have a single stroke, the stacking position will be more misaligned due to the fact that some sheets of paper get caught on other sheets of paper, that they have no stiffness, or that their curls are different.

The present invention has been made in view of the above-mentioned conventional problems, and provides a paper stacking position control device that can reduce the shift and darkness at the stacking position when punched paper is transferred and stacked. The purpose is to write.

In order to achieve this object, the present invention includes a claw that grips the front end of the paper, a brush member that pinches the rear end of the paper, and a tool that connects the mold and the brush member when the mold reaches a predetermined position. and a releasing means for simultaneously releasing the paper and dropping the paper.

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. The figure is an explanatory diagram of an embodiment of the present invention.

The claw 10 grips the front end of the paper after the punching process, moves along the two-dot chain line, and releases its grip on the paper at the claw position shown in the drawing. Walls 11 and 12 surround the paper stacking position, and are actually provided on the left and right sides of the paper stack (in the j direction).

A brush member is constituted by the brush 21 and the iron plate 22, and this brush member is a member C that pinches the rear end of the paper.

Further, this brush member releases the paper C1 in synchronization with the grasping M\bk of the claw 10 when the claw 10 reaches a predetermined position, thereby causing the paper to fall.

The cam 31 rotates around a base shaft 32, and the l''-ra 33 is in contact with the cam surface. This roller 33 is provided at one end of an arm 34, and this arm 34 rotates around a fixed shaft 35. A spring 36 for bringing the roller 33 into contact with the cam surface is threaded onto the other end of the arm 33, and a rack holding member 37 for holding the rack 41 is pivotally attached thereto.

The rack 41 meshes with the binion 42, and this binion 42
rotates together with the gear 43. The gear 43 is held by a mesh holding plate 61 at one end of the spline shaft 50. This holding plate 61 is fixed to a fixed rack 62.

A bevel gear (not shown) is fixed to the other end of the spline shaft 50, and another bevel gear 71 meshes with this bevel gear. The brush 21 is fixed to this bevel gear 71 via an arm 72. This brush 21 is normally inclined as shown and cooperates with an iron plate 82 to sandwich the paper.

A gear 71a is provided integrally with the bevel gear 71, and the gear 71a and the upper part of the rack 80 mesh with each other. Rack 8
The lower part of the 0 meshes with a gear 81, the gear 81 meshes with a gear 82, and an iron plate 82 is fixed to this gear 82.

The retaining plate 91 is connected to the bevel gear 71. Gear 71a, arm 72.
Brush 21. Iron plate 22.5'/80. It directly or indirectly holds the m wheels 81 and 82. Holding plate 91
A gear 92 is pivotally supported on the fixed rack 6.
It meshes with 2. The gear 92 is rotated by a chain wheel 94 via a chain 93. The chain wheel 94 is provided with a handle (not shown), which is manually driven, and has a locking device.

Next, the operation of the above embodiment will be explained.

First, the paper that has finished the punching process located on the right side of the diagram is
The front end is held by the brush 21, and the rear part is held by the brush 21.
and the iron plate 22.

In this case, the roller 33 is in contact with the longer radius portion of the cam 31. When the claw 10 moves to the left in this υ: state, the paper also moves. When the nail 10 reaches a position where the paper is between the walls 11 and 12, the nail 10 hears the sound.

At this time, the long radius part of the cam 31 contacts the roller 33 and does not push the roller 33 downward, so the rack holding member 37 is pushed upward against the spring 3G, and the pinion 42 is moved to the left in the figure. Rotates in the t1 direction when raised. by this,
The spline shaft 50 rotates counterclockwise, and the bevel gear 71 rotates clockwise in the figure. The brush 21 is rotated clockwise via the arm 71 integrated with the umbrella #J wheel 71, and the tip of the brush 21 is raised.

Also, since the gear 71a rotates clockwise, the rack 8
0 is raised, the gear 81 meshing with the rack 80 rotates clockwise, the gear 82 rotates counterclockwise, and the iron plate 22 integrated with the gear 82 also rotates counterclockwise in one direction. As a result, the left end of the iron plate 22 is lowered, so that the speed at which the force pinching the rear end of the paper is released becomes faster. In this case, by pushing only the brush 21 upward, the pinching force of the paper can be reduced.
/i5[However, by lowering the iron plate 22 in synchronization with the pushing up of the brush 21, one part of the paper can be removed.
! 2. The quicker you release the ends, the more accurate the paper stack position will be.

On the other hand, depending on the size of the paper, it may be necessary to change the distance between the walls 11, 12 and move the positions of the brush 21 and iron plate 22 accordingly. In this case, the turn wheel 94 is rotated by hand. This causes the chain 93 to rotate and the gear 92 to rotate relative to the fixed rack 62. For this purpose, the holding plate 91 moves to the left or right, so by adjusting the movement of the holding plate 91, the amount of movement of the brush 21 and the iron plate 22 can be adjusted.

The material of the brush 21 constituting the brush member may be made of a metal other than an iron plate, and may be made of a material other than metal as long as it is relatively hard. The brush 21 may be tilted at an angle other than that shown in the drawings (the angle of inclination is arbitrary).

As described above, the present invention has the effect that when the beaten paper is transferred and stacked, the number of stones falling at the stacking position t can be reduced.
