Abstract

PURPOSE:To restrain the widthwise position of paper leaves in a proper position for separation and delivery by setting side plates in inserting the paper leaves to a position corresponding to the paper leaves having the minimum lateral width. CONSTITUTION:In inserting paper leaves 7, the interval between side plates 2a, 1b is set with reference to the paper leaves 7a having the minimum width. Thus, when the paper leaves 7a are inserted, they are just restrained between both side plates 1a, 1b. Also, when paper leaves 7b having the width larger than the paper leaves 7a are additionally inserted, the paper leaves 7b are deformed. Then, when the paper leaves 7 inserted into a hopper 10 are detected, a pusher plate 2 is moved to pressurized the paper 7 and sandwich the paper leaves 7 between the pusher plate 2 and a front plate 3. Then, the side plates 1a, 1b are moved wide widthwise by a solenoid 4. Thus, the deformation of paper leaves 7b having wider width is eliminated and the paper leaves 7a having smaller width are prevented from the left and right movement.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper sheet separation and feeding device, which is particularly independent of the horizontal dimension (hereinafter referred to as "width") of paper sheets,
The present invention relates to a paper sheet separating and feeding device suitable for separating and feeding paper sheets while restricting the widthwise position of the sheets to an appropriate position.

[Conventional technology]

In conventional paper sheet separation and feeding devices, the side plate is fixed at the widthwise dimension of the insertion opening at the maximum dimension of the paper sheet, regardless of the width of the paper sheet.

Alternatively, as described in Japanese Unexamined Patent Application Publication No. 58-22490, one side is used as a reference and deviation is made only to one side.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, the widthwise dimension of the hopper is defined based on large paper sheets, so when a narrow paper sheet is inserted, the paper sheets become lopsided in the hopper, causing the paper sheets to become uneven. There is a problem in that there is a high possibility of causing a discrimination error when determining the type or an abnormality in transportation.

The present invention has been made in view of the above circumstances, and its purpose is to solve the above-mentioned problems in the conventional paper sheet separation and feeding device, and to solve the problems of the conventional paper sheet separation and feeding device. An object of the present invention is to provide a paper sheet separating and feeding device suitable for separating and feeding paper sheets while regulating the widthwise position thereof to an appropriate position.

[Means for solving problems]

The above-mentioned object of the present invention is to provide a hopper having a side plate for regulating the position of the inserted filter paper sheets in the left-right direction, a front plate and a push plate for regulating the inserted filter paper sheets in the front-back direction, and a paper sheet feeder and a paper sheet separation means. In the paper sheet separating and feeding device, the side plate is set at a position corresponding to the smallest paper sheet in the left and right direction when paper sheets are inserted, and after the paper sheets are inserted, the paper sheets are moved between the front plate and the push plate. This is achieved by a paper sheet separating and feeding device which is configured to be able to retract in the width expanding direction after being held by the paper sheets.

[Effect]

In the present invention, when inserting paper sheets, the interval between the side plates that regulate the left-right direction in the hopper into which paper sheets are inserted is adjusted to the narrowest width of the paper sheets. In addition, when wide paper sheets are inserted, the paper sheets are temporarily deformed in the hopper, but after the side plate is widened and retracted to fit the wide paper sheets, The structure of the side plate has been improved to enable separation operations. In addition, when a large number of large paper sheets are inserted, this side plate is configured so that it can be moved by the pressure of the paper sheets themselves before performing the above-mentioned width widening operation. It's not difficult.

If a mixture of large paper sheets and small paper sheets are inserted, there is a risk that the small paper sheets will move left and right as the large paper sheets recover from their deformation when the side board is retracted. In this case, the widening is performed while the mixed paper sheets are lightly pressed, thereby preventing the movement.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view of a paper sheet separation and feeding device showing an embodiment of the present invention, and FIG. 2 is a view taken along the line A--A. In both figures, 10 is a hopper into which paper sheets 7 are inserted, and the hopper 10 is composed of side plates 1a and 1b, a push plate 2, a front plate 3, and a bottom plate 11.

The side plates 1a, lb are usually used for paper sheets 7 having the narrowest width.
If a paper sheet wider than this is accepted,
It is configured to be easily movable in the direction indicated by the symbol 1 in the figure against the weak spring 6a. In addition, the side plates 1a, l
b is also configured to be able to be moved in the above-mentioned 1-port direction via the link 5 by the driving force of the solenoid 4.

The push plate 2, which is another element constituting the hopper 10, is movable in the direction indicated by the symbol "A" in the figure by a drive means (not shown), and is able to move paper sheets 7 inserted into the hopper 10. It has a function of pressing against the front plate 3 with appropriate pressure. The front plate 3
is provided with a feed-out roller 8 for feeding out the paper sheets 7, and the feed-out roller 8 is rotated by a drive means (not shown) to sequentially feed out the paper sheets 7 in the hopper 10 and separate them. It has the function of separating the sheets one by one using rollers 9 and conveying them to the next process.

The operation of the paper sheet separating and feeding device of this embodiment configured as described above will be described below with reference to FIGS. 3(a) to 3(c).

As mentioned above, when inserting the paper sheet 7, the interval between the side plates 1a and lb is set based on the narrowest paper sheet (referred to as "7a") among the paper sheets 7 handled by this device. There is. Therefore, when the paper sheet 7a is inserted, both side plates 1a
, lb.

Furthermore, if a sheet (r7b) with a wider width is additionally inserted, one sheet 7b will be deformed as shown in FIG. 3(a). Therefore, in this embodiment, after detecting that the paper sheet 7 has been inserted into the hopper 10, the push plate 2 is moved as shown in FIG.
Pressure is applied to the paper sheet 7 by moving it in the "a" direction, and the paper sheet 7 is held between the push plate 2 and the front plate 3. Following this, side plate 1a
, lb are moved by the solenoid 4 in the width widening direction (symbol 1 mouth direction) as shown in FIG. 3(c). This eliminates the deformation of the wide paper sheets 7b and prevents the narrow paper sheets 7a from moving in the left-right direction.

According to the above embodiment, since the interval between the side plates at the time of insertion is set to the interval corresponding to the narrow width paper sheets 7a, the narrow width paper sheets 7a will not be biased toward one of the side plates. do not have. Also, wide paper sheets 7b are the best.

In the case of initial insertion, the width of the side plates 1a, 1b is expanded early against the force of the spring 6a depending on the amount, so that it is not difficult to insert wide paper sheets.

〔Effect of the invention〕

As described above, according to the present invention, there is provided a hopper having a side plate for regulating the position of inserted paper sheets in the left-right direction, a front plate and a push plate for regulating the paper sheets in the front-back direction, and a feeding means and a separation means for paper sheets. In the paper sheet separation and feeding device equipped with Since it is configured so that it can be retracted in the width expanding direction after being held by the front plate and the push plate, separation and feeding can be performed by regulating the widthwise position of each sheet to an appropriate position without being affected by the width of each sheet. This has the remarkable effect of realizing a paper sheet separation and feeding device suitable for
