Abstract

PURPOSE:To aim at the promotion of efficiency in a paper loading job in high stacking paper jogging work, by removing a blanking plate between loaded sheets to a plate receiver adjacent to a paper feeder via a blanking plate conveying device. CONSTITUTION:Sheets loaded on a blanking plate 23 are stacked up on a paper feeding block 3 and then an upper limit of the sheet 24 is made to go up to a paper feeding level H of a high stacking paper jogger with a lifting mechanism driven, whereby paper feeding work for the sheet 24 to the paper jogger is started. When the upper limit of the sheet 24 goes down due to the paper feeding work, the paper feeding block 3 automatically goes up by the lifting mechanism, thus the paper feeding level H is kept up. When loading of the sheet 24 onto the blanking plate 23 is over, an edge of the blanking plate 23 is mounted on a feed wheel 21 of a blanking plate conveying device 11 and transferred onto a feed wheel 22 at the side of a plate receiver 4 by rotation of the feed wheel 21. The blanking plate 23 is moved and mounted on a plate receiving block 9 at the side of the plate receiver 4 adjacent to the blanking plate conveying device 11.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for feeding paper from a paper feed tray to a high stack paper aligning device that stacks sheets in a stack with their corners aligned. This paper pertains to a one-plate pick-up device for a high-stack paper aligning device, which removes a pick-up plate that is inserted between the paper stacks and places stacks of paper at a distance, and also discards defective paper such as twisted paper being fed. .

[Conventional technology]

When printing on paper using a printing machine, it is necessary to feed the paper to the printing machine under the same conditions. Furthermore, when cutting sheets of different sizes to the same size, it is necessary to align the two sides of each sheet. In order to automatically perform this paper alignment work, the applicant of the present application has proposed a high-stack paper alignment device that stacks paper by simply stacking the paper sequentially from the top, thereby improving work efficiency. Although this invention was successful, the paper is gradually transferred to the paper alignment device from a paper feed tray installed close to the paper alignment device.

However, the paper to be placed on the paper feed table is divided into stacks of a fixed number of sheets on a 1 degree basis to maintain the homogeneity of the paper, and each layer is placed in a floating position for the purpose of facilitating the paper loading operation. For this purpose, a board board is placed on the paper feed stand, with the paper stacked at a distance via a corner support member, and the paper is placed on the board for each stack. This involves the work of removing the board from the paper feed tray during paper feeding.

[Problem that the invention seeks to solve]

The above-mentioned paper feed table is designed so that the paper feed position of the paper placed on it, that is, the upper limit of the paper, is always at a preferable position for the paper alignment device, and the table surface automatically rises when the number of sheets decreases. Therefore, the paper feeding position is set higher than the ground plane of the apparatus.

For this reason, when removing the above-mentioned cut-out board, it is necessary to transport the removed cut-out board to a different position each time, which requires a great deal of labor and has problems such as poor workability.

The present invention has been made in view of the above problem, and allows a paper loading operator to easily remove the board placed on the paper feed table when loading paper in high stack paper alignment work. The object of the present invention is to provide a boarding device for a high stack paper aligning device.

[Means for solving problems]

The board removal device for a high stack paper aligning device of the present invention is a paper feeding device that is located close to the high stack paper aligning device and is equipped with a paper feed platform elevating mechanism that maintains the upper limit of the paper feeding position of the sheets placed on the paper feed platform. A plate cradle is provided with a spaced apart part of an appropriate width on either side excluding the paper feeding side and the work side, and the plate cradle is adjusted up and down with the paper feeding position as the upper limit via an appropriate lifting mechanism. In addition to freely supporting the paper feed tray side edge and the plate pedestal side edge of the spaced apart section, in the vicinity of each upper limit position, there is provided a board transfer means which is rotatably driven toward the board pedestal side by a rotational drive device such as a motor. The gist is what has been constructed.

The above-mentioned cut-out board transfer means has rotating shafts arranged near the upper limit positions of the paper feed tray side edge and the board holder side edge of the separation section.

The two rotating shafts are connected to each other for rotational driving by a motor, and
It is composed of a feed roller or a feed plate attached to the rotary shaft, and the rotation speeds of both rotary shafts are varied as necessary, and the two rotary shafts are driven and connected via a ratchet mechanism.

[Created for]

In the stacked sheet sorting device configured as described above, when the sheets placed on the paper feed table are loaded little by little into the high piled paper aligning device via the plate, the paper feed table rises as the number of sheets decreases. , the paper feeding position is kept constant at all times. When loading one stack of paper sheets is finished, the board on which the stack was placed appears, and one operator places one end of the board on the paper feed stand side end of the board transfer means. The cut-out board is conveyed beyond the separation part onto the board pedestal by the rotational drive of the cut-out board conveying means, and since the board pedestal is supported by an elevating mechanism, the upper limit is The position is maintained so as not to be higher than the board transfer means, and after being loaded and stacked in large numbers, it is carried out for use in the fire.

Further, if a defective paper is found during the paper feeding operation, the end of the defective paper is placed on the paper feed stand side end of the board transfer means.

The defective paper is transferred by the rotating drive of the pick-up plate conveying means on the paper feed table side, but due to the flexibility of the paper, it falls to the separating section due to its own weight before it reaches the pick-up plate conveying means on the plate holder side. Therefore, by configuring a means for collecting defective paper below the separating section.

It is also possible to automate the processing of defective paper.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a board-cutting device for a high stack paper aligning device according to the present invention will be described with reference to the drawings. Code 1 is a high stack paper alignment device (
The paper feeding device 1 is a paper feeding device installed adjacent to a paper feeding tray (not shown), and the paper feeding device 1 supports a paper feeding table 3 in a manner that it can be raised and lowered with respect to a base frame 2. , is automatically controlled so that the upper limit of the stacked sheets is maintained at a predetermined height at the arrow H). Reference numeral 4 denotes a temporary receiving device installed adjacent to a partition plate 6 which is erected with an appropriate gap 5 between the base frame 2 and a pan tag and a rough type sunk mounted on a base 7. A plate holder 9 is horizontally pivotally supported on the upper end of the ellipse 8, and constitutes an elevating mechanism that is moved up and down by the drive of a cylinder 10 provided in the link mechanism 8. Further, the driving operation of the cylinder 10 is performed using an operation button (
(not shown), but it is also possible to attach a plate pedestal position detecting means such as a position sensor as necessary and automatically lower the M using a microcomputer.

Reference numeral 11 denotes a sampling plate conveying means constructed above the gap portion 5 at a position slightly higher than the paper feeding level H of the stacked paper aligning device, and the top end of the base frame 2 of the paper feeding device 1 and the partition plate 6. A pair of rotating shafts 14 and 15 are rotatably installed through bearings 12 and 13, respectively. Mechanism 1
An endless chino 19 rotatably connects the chino wheels 18 which are pivotally attached via the chino wheel 7, and the rotary shaft 14 is rotationally driven in the direction of arrow B by the motor 20. Furthermore, the gear ratio of both chain wheels 16.18 is such that the chain wheel 16 is larger than the chain wheel 18, and a plurality of feed wheels 21, 21 are each attached to both rotating shafts 14°15. ..., 22, 22... have different rotational speeds (feed wheel 21>feed wheel 22).

First, a board 23 is placed on the paper feed tray 3 of the paper feed device 1, and a certain amount of paper 24 is loaded onto the board 23. Paper 2 loaded on the board 23 is placed on the paper feed tray 3.
After stacking the paper sheets 24 at the corners of the board 23 with corner support members 25, 25, etc. interposed therebetween to maintain the vertical spacing, the lifting mechanism is driven to raise and lower the upper limit of the paper sheets 24. The high stacked paper aligning device is raised to the paper feeding level H, and feeding of the sheets 24 to the high stacked paper aligning device is started.

When the upper limit of the paper 24 falls due to the above-mentioned paper feeding operation, the lifting mechanism automatically raises the paper feeding tray 3 to the paper feeding level.
■ is retained. If a defective paper such as folded paper or twisted paper is found during the paper feeding, the end of the defective paper is placed on the feed wheel 21 of the sampling plate conveying means 11. In this way, the defective paper placed on the feeder wheel 21 bends downward due to its own weight and is moved sideways, so it is not delivered to the temporary receiving device 4.
The paper falls into the gap 5, and automation of waste paper processing can be achieved by configuring a waste paper collection device below the gap.

During the above-mentioned sheet feeding operation, when the loading of the paper 24 on the pick-up board 23 is completed, the end of the pick-up board 23 is placed on the feed wheel 21 of the pick-up board conveying means 11, and the rotation of the feed wheel 21 causes the paper 24 to be temporarily loaded. It is transferred onto the feeder wheel 23 on the receiving device 4 side. Therefore, the board 23
is a temporary receiving device i'ff adjacent to the extraction plate conveying means 11,
It is moved and placed on the plate holder 9 of No. 4. During this transfer, the opposing feed wheels 21 and 22 have different rotational speeds, but since the feed wheel 22 on the temporary receiving device 4 side is rotatably connected via the ratchet mechanism 17, the board removal plate 23 can be rotated at both ends. Even if they are hung on wheels 21 and 22 at the same time, problems such as slipping will not occur, and due to the difference in rotation ratio, the paper feed table side will move at high speed and the plate holder side will move at low speed.
The board 23 is reliably loaded onto the board holder 9. If the height of the plate 23 becomes higher than the plate transport means 11 due to the loading, the cylinder 10 is driven to lower the plate holder 9 to an appropriate height for use. The plate receiving plates 23 loaded on the receiving stand 9 are collectively provided for the next use.

It goes without saying that the corner support members 25 are also removed when the cutout plate 23 is removed.

〔Effect of the invention〕

As described above, the pick-up device for a high-stack paper aligning device of the present invention can easily remove the pick-up board between the sheets that have been subjected to vL cutting through the pick-up board conveying means to the temporary receiving device adjacent to the paper feed device. Therefore, the practical effects of implementing the present invention are extremely large, such as being able to improve the efficiency of paper loading work in the work of aligning large stacks of paper, and improving work efficiency.
