JP3115766U - Automatic feeder for shredder - Google Patents

Abstract

A shredder auto-feeder is provided which can increase the number of sheets and stably and surely convey cut sheets to the shredder.
Documents placed on a horizontal transport mechanism are less affected by weight even when they are overlapped, and even when they are overlapped, they are naturally easily scattered. A vertical conveyance mechanism is provided substantially at right angles to the horizontal conveyance mechanism, and the vertical conveyance mechanism has a conveyance belt and a suction roller. The document mounted on the horizontal transport mechanism is pressed against the vertical transport mechanism, and the strength of the press contact is always kept optimal by controlling the forward, reverse, and stop of the horizontal transport.

Description

  The present invention is a shredder with an auto feeder that is an integrated combination of an auto feeder that automatically supplies cutting paper to a shredder for document processing.

  A shredder with an auto feeder that combines an auto feeder with a shredder has been proposed.

  Conventional shredders with an auto feeder generally have a system in which sheets to be cut are stacked horizontally and conveyed from the lower part, or a system in which the sheets are mounted upright and conveyed from the surface.

  Further, in the conventional auto feeder, since the cut sheet is a used sheet, the paper may stick to the folded or curved habit, and it has been difficult to perform stable overlapping.

Problems that the device tries to solve

Therefore, the conventional auto feeder has the following problems.
(1) When the paper is baked to a predetermined number before the cut paper is transported, the conditions of the paper are easy to change due to the paper habit caused by the folding and bending of the cut paper, and it is difficult to increase and stabilize the number of baked paper. .
(2) The small number of Sabaki method required a lot of cutting time when there was a lot of cutting paper.
(3) If the feeding speed is increased in order to shorten the cutting time, the paper will be bent and the curved paper will cause meandering, which will cause jamming of the cutting paper.

  Accordingly, an object of the present invention is to provide a shredder auto-feeder that solves the above-described problems of the prior art, and that can increase the number of sheets and stably convey the cut sheet to the shredder.

Means for solving the problem

  In order to achieve the above object, an auto feeder according to the present invention is characterized in that a cut sheet is stood and accommodated, and a receiver for the cut sheet is mounted on a horizontal transport mechanism and pressed against the vertical transport mechanism.

  In addition, the roller roller is provided for vertical conveyance, and the vertical conveyance mechanism is in long contact with the cutting paper conveyance direction.

  In addition, the vertical transport mechanism has a long paper transport belt on both sides in the vertical direction, and the lower part of the central paper transport belt is short. ing.

  In addition, the cutting paper mounted upright on the horizontal conveyance mechanism maintains the optimum pressure contact with the vertical conveyance mechanism by driving the horizontal conveyance. In other words, when the pressure contact is weak, it is driven in the pressing direction, and when it is strong, it is driven backward or stopped to make the pressure contact stronger than necessary, making it less susceptible to paper habits.

Effect of device

  The cutting paper is mounted upright on the horizontal transport mechanism, and it is properly pressed against the vertical transport mechanism, and the Sakiki method using the belt and Sabaki roller has been established. It was difficult to receive, and even if the number of peels was increased, it was possible to carry out the stable operation.

  In addition, the belt used for the horizontal conveyance mechanism that receives the cut sheets placed upright is made of a material with a small friction coefficient. When the cut sheets are pressed against the vertical conveyance mechanism, the belts of the cut sheets and the horizontal conveyance mechanism are easy to slip. As a result, it was possible to easily set the pressure contact of the cut paper and establish a stable peel.

  In addition, the peripheral speed of the roller roller included in the vertical conveyance mechanism is set to be faster than that of the vertical conveyance belt, and thus the cutting paper that is mounted upright has a pulling force acting on the lower portion, thereby smoothing the vertical conveyance.

FIG. 1 shows an external view of an A feeder according to the present invention mounted on a B shredder.

FIG. 2 is a summary view of a vertical transport mechanism according to the present invention. 1.2 is a vertical conveyor belt, 3.4.5.6 is a rotating shaft that transmits rotation to the belt, 7 is a rotary bearing, 8 is a roller roller, and the peripheral speed of the roller roller is faster than the conveyor speed of the vertical conveyor belt of 1.2. Is set. The take-in roller 9 is a roller for reliably taking the cut document that has been sucked by the 8 roller and feeding it to the shredder. Reference numeral 10 denotes a driving gear which transmits a driving force to the rotating shaft of 3.4.5.6.

FIG. 3 is a summary view of the lateral transport mechanism according to the present invention. The 11 horizontal conveying belts are made of a material having a small coefficient of friction, and are combined with the 2 vertical conveying belts at a substantially right angle, and have a gap through which the cut paper that has been baked is passed. Reference numeral 12 denotes a sliding receiving plate for holding the horizontal conveyance belt, which enables stable feeding without bending the horizontal conveyance belt even if a cut sheet is mounted on the 12 horizontal conveyance belt. The 13 plate is opposed to the 8 plate roller provided in the vertical conveyance mechanism, and determines the number of sheets to be cut by changing the gap of the plate. The 13 plate is more concave than the 11 side conveyor belt. 14.15 is a rotating shaft that gives rotation to the 11 horizontal conveying belts. 16 is a rotary bearing of 14.15. Reference numeral 17 denotes a drive gear that transmits rotational drive to 14.15. The paper receiving plate 18 is a receiving plate that prevents the paper from falling over when the cut document is mounted, and is closely attached to the cut document by a 19 spring.

FIG. 4 is a summary view showing a state in which the A auto-feeder according to the present invention is mounted on the B shredder, and the cut document is conveyed to the paper shredder. Twenty cut documents are attached to eleven lateral transport belts. At this time, 20 cut documents are always pressed against 20 cut documents by 19 springs so as not to fall down by 18 paper receiving plates. It is held by twelve slip receiving plates so that it does not bend even if twenty cut documents are attached to eleven horizontal conveying belts. It rotates in the direction of the arrow D and presses twenty cut documents to one vertical conveying belt. To do. The one vertical conveying belt rotates in the direction indicated by the arrow B, and the 20 cut documents that are in pressure contact are conveyed in the direction indicated by the arrow B. Further, the 8 roller is rotating in the direction of the arrow C, and the peripheral speed at this time is faster than that of the 1 vertical conveying belt, so that it can be reliably sent to the 9 intake rollers. Further, the eleven horizontal conveying belts are controlled so as to rotate or stop in the direction of the arrow E so that the 20 cut documents are kept in proper pressure contact with the one vertical conveying belt. In this way, 20 cut documents pass through the crevice part crevice gap, and are conveyed to the cutter to the B shredder part via the 9 intake rollers. The guide plate 21 is a guide plate for smoothly feeding 20 cut documents to the shredder, and the 20 cut documents are shredded like a chamfer.
