Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for taking out sheet-like articles such as paper sheets held in an accumulated state one by one and a method of using the apparatus.

[0002]

2. Description of the Related Art Conventionally, various mechanisms have been known as a mechanism for stacking sheets of paper sheets or the like and feeding them one by one from the uppermost or the lowermost one to a processing machine or the like. In such a case, since the money is not processed and the machine is not used so much, the tickets are handed out one by one.

[0003]

If complicated processing such as money transfer is not required, for example, issuance of a reservation ticket for a lottery ticket, it suffices that the tickets be issued one by one without fail, instead of manually. Since there is no simple and highly convenient ticket issuing device that can be used, the staff members manually issue tickets one by one in the past. However, there is a problem that the burden on the staff increases as the number of issued tickets increases. Also, unlike things like pamphlets and leaflets, it's a problem to have lottery ticket reservations taken away without any restrictions.
You can't just stack them up and get them freely. Such a situation is not limited to the case of a lottery, and in order to solve this, it is necessary to develop a highly convenient device that can reliably take out sheet-like articles one by one with a simple mechanism. Met.

The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to reliably take out sheet-like articles held in an accumulated state by stacking one by one by a simple mechanism. To do.

[0005]

SUMMARY OF THE INVENTION According to the present invention, sheet-like articles stacked and held in an aligned state are arranged from one side in the stacking direction.
A sheet-like article take-out device for surely taking out sheets one by one, a work holding means for accumulating and holding sheet-like articles, and a biasing means for biasing the work holding means toward one side in the work accumulating direction, The first sheet-shaped article held by the work holding means is pressed against the first sheet-shaped article at a position separated from the workpiece removal position by a first distance, and the first sheet-shaped article is taken out of the sheet-shaped article during the taking-out operation. Of the first roller that is rotated by the frictional force of the first roller and the sheet-like article held by the work holding means at a position away from the first roller by a second distance rearward in the work take-out direction, and a transmission means such as a belt. The second sheet-like article is driven and connected to the first roller through the first roller and is transmitted to the first roller to rotate in the same direction, so that the second sheet-like article is transferred to the second sheet in the latter half of the taking-out operation of the first sheet-like article. Between the article It is provided with a second roller to push the workpiece take-out direction by the force.

[0006] In the above configuration, to push to ensure a predetermined amount of the second sheet of the work in the entry direction without first sheet workpiece (sheet-like article) moves the third piece of the workpiece when retrieved, the position of the first roller and the second roller, characterized in that set so that the sum of the first distance and the second distance is smaller than the difference between the width and the second distance of the take-out direction of the sheet-like article And

[0007] In addition, 2 when the removal of the first sheet of the work
In order to allow the tip of the third work piece to protrude from the work take-out opening by a predetermined amount and prevent the third work piece from entering the work take-out opening, a pair of gate members are provided at the work take-out opening. provided with a preferably provided a gate adjustment mechanism that can adjust the size relationship between these gate members.

Further, the biasing means biases the work holding means so that the work holding means moves smoothly and holds the frictional force between the work and the first and second rollers at an appropriate and uniform value. In addition, in order to facilitate the replenishment of the work, the work holding means is constituted by a stand for vertically stacking and holding the sheet-like articles inside the apparatus main body, and the work holding means is mounted on the side plate of the apparatus main body. A guide groove is provided which guides a pair of upper and lower guide rollers provided on the left and right side surfaces to allow the platform to move up and down, and a handle member is disposed on at least one of the side plates, and the handle member is provided with the guide groove. And a locking member is provided at the lower end of the handle member, and an engaging groove is formed at the lower end of the guide groove so that the locking member can be engaged. And the engaging part It is preferable to constitute a click mechanism.

In use of the sheet-like article take-out device having the above-mentioned construction, the work-holding means holds the sheet-like articles in an accumulated state, and the first roller is manually rotated to move the leading end of the first sheet-like article. The first sheet-shaped article can be taken out by pulling the tip portion by projecting it from the work take-out port by a predetermined dimension, and the dimensional relationship between the gate members is set so that when the first sheet-shaped article is taken out, The leading edge of the second sheet-like article pushed forward in association with the take-out operation can pass between the gate members while overlapping with the rear edge of the first sheet-like article, but up to the third sheet-like article Can be adjusted to have a dimensional relationship that does not allow entry.

[0010]

The sheet-like articles are vertically stacked and held by the work holding means, and the work holding means is urged in the stacking direction (for example, upward) by the urging means, whereby the first roller and the second roller It is pressed against the roller with a predetermined load. In this state, when the first work is projected by a predetermined dimension in the work taking-out direction by, for example, manually rotating the first roller, the first (for example, top) sheet-like article (work) is The first piece of work can be taken out by pulling the tip. At that time, the first roller rotates due to the frictional force as the first work is taken out. Further, the second roller also receives the frictional force between the first roller and the first roller in the initial stage of the take-out operation of the first roller, and rotates in synchronization with the first roller. After the work has been disengaged from the second roller, the work comes into contact with the second work and is driven by the first roller to push the second work in the work taking-out direction by the frictional force. When the first sheet of work is disengaged from the first roller, the first roller and the second roller stop, and the tip of the second sheet of work protrudes in the work take-out direction by an amount approximately the same as the distance between the rollers. This state is maintained until the first work piece is taken out, and as a result, this second work piece becomes a new first work piece and can be taken out the next time.

Further, the distance between the work take-out position and the first roller (first distance) plus the distance between the first roller and the second roller (second distance), that is, the work take-out position. from the distance to the second rollers, for the outlet direction of the width of the workpiece is smaller than a value obtained by subtracting the second distance, the first roller by the first sheet of the workpiece deviates from the first roller The second roller continues to push only the second work piece until the second roller stops, and the third work piece does not move.

[0012] By adjusting the dimensional relationships between the gate and the tip portion of the second sheet of the work when the work take-out is protruded from the workpiece outlet in a state overlapping the rear end portion of the first sheet of the work Although it is possible, the third work can be prevented from entering the work take-out port.

Further, according to the present invention, the loading table constituting the work holding means can be smoothly moved by the guide roller being guided by the guide groove provided in the side plate on the apparatus main body side, whereby the biasing force is exerted. Can be uniformly applied to maintain the frictional force between the work and each roller at an appropriate and uniform value.
