[Prior art]
Paper cut at a paper mill or printed at a printing factory is automatically stacked on a paper tray. The stacked paper is divided into reams of a certain number of sheets and sent to the next process such as packaging, binding, and banding. In order to divide the stacked paper into a certain number of reams, the number of paper is automatically counted, and marker tape is supplied from the tape inserter for each predetermined number of sheets, and between the stacked paper It is caught.
Conventionally, it is difficult to automate the work of dividing the stacked paper with the marker tape sandwiched into reams of a certain number of sheets at the position of the marker tape and transferring it to the next process. We had to rely on the manual work of moving by hand and transferring to the next process. However, with the speeding up of the papermaking and printing processes, paper reaming work becomes increasingly labor-intensive, and the subsequent processes such as packaging are automated and only the ream division remains as a manual work. It is strongly desired.

DETAILED DESCRIPTION OF THE INVENTION
The method and apparatus of the present invention can be applied to the ream division of paper that has been cut and printed in a paper factory or printing factory and stacked on a paper tray. In the cutting process, a plurality of sheets that are usually cut at the same time are supplied to the paper tray, and in the printing process, the normally printed sheets are supplied one by one to the paper tray. The number of sheets supplied to the sheet receiving tray is automatically counted, and a marker tape is sandwiched by the tape inserter with a predetermined number of sheets as one ream. The number of one ream is appropriately selected depending on the paper quality, the size of the paper, the use of the paper, and the like, but is usually usually 100 to 500.
In the present invention, the marker tape is inserted as a two-layer marker tape instead of the normal one for each ream unit of paper stacked on the paper tray. There are no particular restrictions on the method of supplying two marker tapes in a stacked manner. For example, two tapes 2 drawn from two tape rolls 1 can be supplied through a tape inserter 3 as shown in FIG. Alternatively, a single tape roll around which two tapes are wound can be used.
FIG. 2 is a perspective view showing the state of the paper stacked on the paper cradle. The paper 4 sent from the previous process is accurately positioned by the three stoppers 5 and stacked on the paper receiving tray 6 in a uniform manner. The number of sheets sent to the paper tray is counted by a counter (not shown), and when a predetermined one reamer is reached, a two-layer marker tape 7 is supplied from the tape inserter 3, and the paper It is cut while sandwiched between them. When a predetermined amount of paper has been stacked on the paper cradle, two marker tapes are inserted on the paper cradle at equal intervals for each ream of the paper.
[0006]
The paper cradle that has finished stacking a predetermined amount of paper is sent to the next process, and the paper is divided for each ream. In dividing the ream, first, the uppermost two stacked marker tapes of the paper trays that have been stacked are opened. There are no particular restrictions on the method of opening the two marker tapes, for example, a method of separating by mechanical clamping, a method of adhering and separating the adhesive tape to each of the two marker tapes, a method of separating by vacuum using a suction cup Etc. can be used. Among them, the method using a suction cup can be preferably used because the used marker tape can be released by returning to normal pressure or slightly increasing pressure. FIG. 3 is a partial side view showing a state in which the marker tape is opened by the suction cup. In this figure, the uppermost marker tape of the two stacked marker tapes 7 inserted into the stacked paper 4 is opened up and down using two suction cups 8.
4A is a plan view illustrating one embodiment of the present invention, and FIG. 4B is a side view. In this figure, the two uppermost marker tapes 7 of the paper tray on which the paper has been stacked are opened by the suction cups 8. The partition plate 9 is inserted between the two opened marker tapes and pushed up by the ascending cylinder 10 to lift the end of the uppermost one-ream paper 11 between the remaining lower paper. A slight gap is produced. Next, the presser plate 12 is inserted between the uppermost one ream paper and the remaining lower paper, and the lower remaining paper is pressed and fixed. During this time, the end portion of the uppermost one-ream paper is supported by the stopper 13, so there is no possibility of causing a positional shift. After the remaining paper at the lower part is pressed and fixed by the presser plate, the stopper is removed and the uppermost one ream paper is pushed by the pusher 14 to move to the next process. The movement of the uppermost one ream paper can be performed by an arbitrary method such as using a pusher and moving by gripping the end with a clamp.
After the topmost one piece of paper is moved to the next process, the same operation is repeated since the two marker tapes are opened again, and all the paper on the paper tray is divided and moved one by one. The positioning of the two-layer marker tape and the partition plate, that is, the alignment of the uppermost one-ream paper with the presser plate, stopper, and pusher, raises the paper cradle step by step using a lifting device. Or by lowering the partition plate, the pressing plate, the stopper, and the pusher step by step using an elevating device.
[0007]
In another aspect of the present invention, the marker tape is inserted obliquely so that both ends of the marker tape are exposed at the corners of the paper for each ream unit of the paper stacked on the paper cradle. There is no restriction | limiting in particular in the method of supplying a marker tape diagonally, For example, it can carry out easily by installing a tape inserter in the diagonal position with respect to the paper stacked. FIG. 5 is a perspective view showing the state of the paper stacked on the paper cradle. The paper 4 sent from the previous process is accurately positioned by a stopper (not shown), and stacked on the paper receiving tray 6 in a uniform manner. The number of papers sent to the paper tray is counted by a counter (not shown), and when a predetermined amount of ream is reached, the marker tape 7 is supplied from the tape inserter 3 to the corner of the paper. The both ends are sandwiched and exposed. When a predetermined amount of paper has been stacked on the paper cradle, marker tapes are inserted on the paper cradle at regular intervals for each ream of the paper.
The paper cradle that has finished stacking a predetermined amount of paper is sent to the next process, and the paper is divided for each ream. In dividing the ream, first, the marker tape at the top of the paper cradle after stacking is lifted. The method for lifting the marker tape is not particularly limited, for example, a method in which the exposed ends of the marker tape are mechanically clamped with a clamp or the like, a method in which an adhesive tape is attached to the exposed ends of the marker tape, and a method for lifting the marker tape. It is possible to use a method of attracting and lifting both exposed ends of the film by reducing the pressure using a suction cup. Among them, the method using a clamp can be preferably used because the marker tape can be clamped by one clamp after the ream division of the paper is finished, and the used marker tape can be discarded. FIG. 6 is a partial perspective view showing a state in which the exposed ends of the marker tape are clamped and lifted by a clamp. In this figure, the uppermost marker tape among the marker tapes 7 that are inserted obliquely with both ends exposed to the stacked paper 4 is lifted by using two clamps 15.
[0008]
A partition plate is inserted into a gap formed by sandwiching and lifting both ends of the uppermost marker tape of the paper tray on which the paper has been stacked. By pushing up the partition plate by the rising cylinder, the edge of the uppermost one-ream paper is lifted, creating a gap between the remaining paper at the bottom. Next, a pressing plate is inserted between the uppermost one ream paper and the remaining lower paper, and the lower remaining paper is pressed and fixed. During this time, it is possible to prevent the positional deviation of the uppermost one-ream paper by means such as supporting the end of the uppermost one-ream paper with a stopper. After pressing the remaining paper at the bottom with the presser plate, the stopper is removed and the topmost piece of paper is pushed with a pusher, or the end is clamped to move to the next process. To do.
After moving the top one piece of paper to the next process, the same operation is repeated by holding the both ends of the marker tape that is inserted diagonally and exposed at both ends, and the same operation is repeated. Divide by ream and move. The alignment of the marker tape and the clamp with both ends exposed, that is, the alignment of the uppermost one-ream paper with the pressing plate, stopper, pusher, etc., raises the paper cradle step by step using a lifting device. Or by lowering the clamp, the pressing plate, the stopper, and the pusher step by step using the lifting device.
[0009]
