Description

 The present invention claims the priority of the Chinese patent application filed on May 17, 2012, the Chinese Patent Application No. 201210153172.3, entitled "A Paper Accumulation Device", the entire contents of which are incorporated by reference. Combined in this application. Technical field

 The present invention relates to a sheet accumulating device, and more particularly to a sheet accumulating device for transporting banknotes, checks, and coupons by means of a stack of bills.

Background technique

 The paper sheet accumulating device is a device for accumulating paper sheets (for example, banknotes, checks, coupons, etc.) in a predetermined number of sheets (for example, 100 sheets) and accumulating them in the stacking unit. The paper sheet accumulating device receives the continuously conveyed paper between any two adjacent stacking roller sheets and rotates the conveyance, and causes the paper to fall to the stacking portion. The device powers the paper by the transport wheel, and the paper is stored longitudinally or laterally between any two stacking roller blades, so that the paper is rotated and transported as the stacking roller rotates, and is transported to the accumulating portion for stacking. During the rotation of the paper with the stacking wheel, the head of the paper is inserted at the root of the two stacking rollers, and the tail of the paper passes over the transport wheel, along with the paper head to rotate with the stacker.

 The existing paper-like accumulating device has a relatively large gap between the stacking roller blades, and does not have enough force to clamp and rotate the paper. Therefore, under the action of the rotating centrifugal force, the head is getting farther away from the root of the stacking roller. The paper is separated from the range between the two stacking rollers, causing the paper to be scattered and the stacking is not neat. Summary of the invention

 An object of the present invention is to provide a paper sheet accumulating device which can reliably store paper sheets between the wheel sheets, and can prevent the paper sheets stored between the wheel sheets from being scattered, thereby enabling the paper sheets to be geotagged. They are stacked on the accumulation unit.

The present invention provides a paper sheet accumulating device comprising a transport portion, a clamping portion, a guiding portion and an accumulating portion which are sequentially connected; The transport portion is configured to transport paper sheets to the clamping portion;

 The clamping portion includes a driving shaft and a plurality of stacking rollers fixed on the driving shaft, each of the folding rollers having a plurality of wheels with the same arc, and the clamping between any two adjacent rollers Holding a sheet of paper and rotating it to the guide;

 The guiding portion 7 is connected to the sheet conveyed by the clamping portion and guided to the sheeting portion;

 The accumulating portion is for accumulating paper sheets conveyed by the guide portion.

 Further, the wheel curvatures of the plurality of banknote rollers are different.

 Further, the plurality of stacking wheels, the wheel curvature of at least one of the stacking wheels is different from the wheel curvature of the other stacking wheels.

 Further, the wheel opening directions of the plurality of banknote rollers are the same.

 According to the present invention, by adding a third banknote roller of different curvature between the first stacking roller and the second stacking roller, the paper sheets can be reliably stored between adjacent wheel segments, and in addition, can be stored. The surface of the paper sheet forms a crease-like crease, thereby increasing the friction between the wheel and the paper sheet, thereby effectively preventing the paper sheet from coming off the wheel of the stacking wheel, so that it can be evenly distributed and laminated. Accumulate, avoid confusion.

detailed description

 The present invention will be further described in detail below with reference to the accompanying drawings.

Fig. 1 is a side view showing a sheet accumulating device of an embodiment of the present invention. The paper sheet accumulating device 16 of the present invention is a device for storing paper sheets 11 such as banknotes, checks, and coupons in a longitudinal or horizontal direction, and a transport portion, a clamping portion, a guiding portion 12 and an accumulating portion 15 which are sequentially connected; The transport portion includes a pair of transport rollers (10, 10') for transporting the paper sheets 11 to the nip portion;

 The clamping portion includes a driving shaft and three stacking wheels 13 fixed on the driving shaft, each of the stacking wheels 13 having a plurality of wheels 14 of the same arc, and any two adjacent discs The paper sheet 11 can be held and rotated to the guide portion;

 The guiding portion 12 7 is connected to the paper sheet 11 conveyed by the clamping portion, and guided to the accumulation portion 15;

 The accumulating portion 15 is for accumulating the sheets 11 conveyed by the guiding portion 12.

 The working principle of the present invention is to continuously feed the sheets 11 to the stacking wheel 13 one by one at a constant speed in the fixed direction by the transporting pair (10, 10'). Further, the paper sheets 11 are rotated and conveyed one by one by the stacking rollers 13, and the left and right sides of the transport end of the paper sheets 11 are transported while being joined to the guide portion 124. Thus, the sheet 11 is moved along the guide portion 12 which is inclined downward from the middle of the conveyance. Finally, the sheet 11 is separated from the stacker 13 and accumulated in the accumulating portion 15 due to its own weight.

 As shown in FIG. 2, the three stacking rollers 13 have a pair of first stacking rollers and second stacking rollers 13a of the same arc, which are fixed to the drive shaft 20 at a narrower interval than the width of the sheet 11; The three-stack roller 13b is fixed to the drive shaft 20. As shown in FIG. 3, the third stacking wheel 13b has the same phase as the first stacking roller and the second stacking roller 13a, but the third stacking wheel 13b has the same wheel. The sheet 14b is different in curvature from the wheel 14a of the first stacking roller and the second stacking roller 13a, and the opening curvature is uniform to ensure the smooth insertion of the paper sheet 11.

The present embodiment is characterized in that the third stacking wheel 13b is configured in such a manner that the phases of the first stacking roller and the second stacking roller 13a are the same and the arcs are different, thereby entering any first stack of bills. The sheet 11 between the wheel and the adjacent wheel piece 14a of the second stacking roller 13a forms an upward convex crease in the center of the sheet 11 under the action of the wheel 14b of the third stacking wheel 13b. 30, or forming a crease 31 having a downward concave shape. In this way, the paper sheets 11 accommodated between the wheel pieces 14a are rotatably conveyed in a state in which a certain amount of frictional force is applied to the folds 30, 31 by the uneven shape. Thereby, at the time of the rotation conveyance, it is possible to prevent the sheet 11 from being easily detached from the wheel piece 14 of the first, second, and third stacking rollers 13. The scattering of the paper sheets 11 is prevented from being spoiled. Further, in the present embodiment, as shown in FIG. 3, it is assumed that the tip end of the adjacent wheel piece 14a of the first and second banknote rollers 13a has a distance p along the outer circumference circle, and the wheel of the third banknote wheel 13b The sheet is designed to be the same as the first and second stacking wheels 13a, and the curvature of the wheel 14b of the third stacking wheel 13b is designed to be in the arc of the wheel 14a of the first and second stacking wheels 13a. Different, the minimum is 1/2 pitch l/2p, but the arc of the opening is the same, or a little different, to ensure the smooth insertion of the paper sheet 11. However, the minimum distance of the arc is not limited to 1/2 pitch l/2p, and the same effect can be obtained by arranging the 1/2 pitch l/2p as the center and being shifted back and forth; and the shape of the arc is not limited. , can be any shape structure.

 The above is a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. It should be noted that those skilled in the art can also omit the principles of the present invention without departing from the scope of the present invention. A number of improvements and modifications are also made, which are also considered to be within the scope of the invention.
