Abstract

PURPOSE:To surely stack the set fixed number of copies while continuously operating a paper discharging machine at high speed. CONSTITUTION:When the detected value reaches the set value after detecting a discharge paper 4 by a sensor 31, a belt conveyer device 10 is operated, so as to move a discharge paper stack. Simultaneously, a temporary receiving device 20 is operated, and temporary receiving bars 21 are protruded upward from a conveyer belt 12, so as to temporarily receive the discharged paper for the next discharge paper stack. When the conveyer belt is moved by one pitch, the temporary receiving operation is released, thereby the temporary receiving bars are retreated, and the temporarily received discharge paper is dropped on the conveyer belt 12. The discharged paper stack having the set amount can be efficiently conveyed in the state where a paper discharging machine is operated at high speed by performing the temporary receiving operation during the conveyer belt is moved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single sheet of advertising paper or the like, a plurality of sheets of newspaper or the like, and an aggregate paper such as a signature, which are partially or plurally stacked and continuously stacked. The present invention relates to a sheet discharging and conveying apparatus that discharges and stacks sheets, and particularly to a sheet discharging and conveying apparatus suitable for continuously performing stacking operations without stopping a sheet discharging machine.

[0002]

2. Description of the Related Art Conventionally, a method of stacking a predetermined amount of discharged paper continuously discharged from a paper discharge machine by cutting off, sorting by hand, and intermittent operation has been used. According to the set cutting method, the discharged paper continuously discharged in the form of sashimi is cut off at a constant interval in the middle of the paper and the paper between them is stacked. The manual sorting method is one in which a counter mark or the like is attached to the discharged sheets that are continuously discharged in a sashimi state, and the sorting is done manually by a person at the final stage. Further, the intermittent operation method is to temporarily stop the paper discharge machine every time the set number of copies is discharged, and restart the paper discharge machine after the stacked conveyor moves one pitch.

[0003]

However, in the case of the set-cutting, the number of stacks tends to vary, and the device becomes large-scale, which requires a large space and is expensive. Also, in the case of manual sorting, when it is discharged at a high speed, a great deal of labor is required for its processing, at the same time, considerable skill is required, and counting is likely to occur because it depends on human eyes. Furthermore, in the case of intermittent operation, there is a problem in mechanical strength due to the impact due to repeated operation and stoppage, and there is a problem in that the overall average speed is also reduced. It is an object of the present invention to provide a paper discharge conveyance device that conveys a set number of copies while reliably stacking them while operating the paper discharge machine at high speed.

[0004]

In order to achieve the above-mentioned object, the present invention discharges the discharged sheets of newspapers, advertisements, etc. one by one at intervals, stacks the discharged sheets at a set amount, and conveys them. In the paper discharge conveyance device, a paper discharge detection unit that detects the paper discharge, a conveyance unit that conveys the paper discharge stack of the set amount,
The temporary receiving portion for temporarily receiving the discharged discharged sheet, the first position for temporarily receiving the discharged sheet, and the temporary receiving portion for the second position for passing the temporarily received discharged sheet to the conveying means. When the discharge amount detected by the discharge detecting unit reaches the set stack amount, the transfer unit is instructed to move to a position for receiving the next discharge stack when the discharge amount detected by the discharge detecting unit reaches the set stack amount. At the same time, the temporary receiving section is issued an operation command to the first position of the temporary receiving section, while when the conveying means moves to a position for receiving the next sheet stack, the temporary receiving section is sent to the temporary receiving section. And a control means for issuing an operation command to the second position of the.

[0005]

When the set amount of discharged paper is discharged to the conveying means, the control means drives the conveying means to move the discharge stack. At the same time, the temporary receiving operation of the temporary receiving means is started, and the next paper discharge is temporarily received. This temporary receiving operation is performed during the movement of the transporting means.
Then, when the movement of the conveying means is completed, the temporary receiving operation of the temporary receiving means is canceled, and the temporarily received discharge stack is discharged to the conveying means. As described above, the set amount of the discharge stack can be efficiently discharged and conveyed without stopping the discharge operation of the discharged paper.
