Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet bundle quantity sorting technique for sorting a conveyed sheet bundle according to a preset quantity.

[0002]

2. Description of the Related Art For example, a sheet bundle of sheets or the like, which has been bound or bound by a bookbinding machine, is successively carried out from the bookbinding machine in a half-overlaid state by a conveyor. In this case, in order to easily know the number of sheet bundles carried out from the bookbinding machine, the sheet bundles conveyed on the conveyor are classified according to a preset number. This division is generally performed by shifting one of the sheet bundles conveyed by a preset quantity in a direction perpendicular to the conveying direction.

[0003]

However, in order to shift one of the conveyed sheet bundles in the direction perpendicular to the conveying direction, it is difficult to push out the side surface of the sheet bundle, and the division for extruding the side sheets is difficult. There are restrictions on the arrangement of the devices, which makes it difficult for the user to set the devices.

The present invention has been made in view of the above-mentioned difficulties, and provides a sheet bundle quantity sorting method and apparatus capable of sorting a sheet bundle conveyed by a conveyor in a semi-overlapped state and easily installed on the conveyor section. The purpose is to provide.

[0005]

The above objects of the present invention can be achieved by the following items (1) to (3).

(1) Upward and downward moving pins are arranged above a conveyor for conveying a bundle of sheets in a half-overlapped state, and the pins are lowered by a predetermined number in a gap between the overlapping of the bundles of sheets. A method for classifying the number of sheet bundles, which is brought into contact with the thickness end face of the sheet bundle on the upper side of the semi-overlapped state conveyed by a conveyor to change the direction of the set number of sheet bundles.

(2) A driving source for driving a preset number of sheet bundles conveyed in a semi-overlapped state and a pin that moves up and down by the drive of the driving source are provided, and the pins convey the sheet bundle. It is placed above one side of the conveyor and is conveyed by the conveyor at the lowest position of the pin.
An apparatus for sorting the number of sheet bundles, which is characterized in that it is in contact with the thickness end surface of the upper sheet bundle in the half-overlapped state .

(3) A driving source for driving a preset number of sheet bundles conveyed in a semi-overlapped state, a pin that moves up and down by the driving of the driving source, and a rotatably arranged near a lower end of the pin. And a lower end of the roller protruding below the lower end of the pin,
The lower tip of the roller is arranged on the downstream side of the lower tip of the pin in the sheet bundle conveying direction, the pin is arranged on one side above the conveyor that conveys the sheet bundle, and the pin is at the lowest position. Half-stacked form conveyed on a conveyor
A sheet bundle quantity sorting device, characterized in that it comes into contact with the thickness end face of the upper side sheet bundle.

According to the above feature of the present invention, the pin is actuated for each preset number of the sheet bundle conveyed by the conveyor, and the tip end of the pin is biased to one side of the sheet bundle conveyed by the conveyor. The sheet bundle is brought into contact with the thickness end face, and the conveyance of the sheet bundle at the contact position is temporarily delayed. As a result, the sheet bundle with which the pins are brought into contact with each other has its direction changed with respect to other sheet bundles conveyed by the conveyor. The number of sheet bundles can be easily known from the sheet bundle whose direction is changed.

Further, the change of the direction of the conveyed sheet bundle is
Since the pins are moved up and down, even if the bundle of sheets being conveyed is in a half-stacked state, it is sufficient if the pins are lowered during the period when the stacks are misaligned, and there is a lot of margin in how to lower the pins. The timing of sorting the bundle of sheets becomes easy, and at the same time, the apparatus for sorting the number of bundles of sheets can be easily installed in the sheet bundle discharge port of a bookbinding machine or the like.

Further, when the roller is installed so as to project from the tip of the pin, the sheet bundle preceding the sheet bundle whose orientation is changed is pressed, so that the sheet bundle preceding the sheet bundle due to the change in the orientation of the sheet bundle by the pin is moved. It is possible to clarify the division of the sheet bundle without any influence on the sheet.
