Abstract

PURPOSE:To secure the coincidence between the left and right gaps formed by a feed roll and a feed block and therefore to prevent the meandering of a paper sheet by providing plural feed blocks along the axial center of a feed roll and controlling individually these feed block positions by means of a stopper. CONSTITUTION:The paper sheets 34 are stacked on a hopper 8 of a paper sheet counter, a these paper sheets are fed one by one by a feed roll 19 and a hopper roll 12 set at the bottom of the hopper 8. Then plural feed blocks 35 having arcuate separation surfaces 27 opposing to the outer circumference of the roll 19 are provided. A stopper 49 is set in parallel to the axial center of the roll 19. This stopper can freely get close to or away from the block 35. Such a stopper 49 is properly controlled to get coincidence between the left and right gaps formed by the block 35 and the roll 12. In addition, a recess is formed along the roll 19 and at an opposite position to the block 35. Then the meandering of the sheet 34 is eliminated with the control of the stopper 49. Thus, the sheet 34 can be smoothly fed.

Description

[Detailed description of the invention] Technical field of invention This invention relates to a paper piece counting machine.

Technical background of the invention and its problems First, conventional examples are shown in FIGS. 1 to 3. Main body (1)
A power switch (2), a keyboard (3), a counter display (4), a preset display (5), a completion ramp (6), and an error lamp are arranged on the front of the machine.

Further, a hopper (8) is formed in the upper part, and a stacker (9) for storing pieces of paper such as banknotes is provided in the lower part.

The hopper (8) is equipped with several presser bodies (lυ) having presser springs (lll) so as to be movable up and down.

As shown in Figure 2, an eccentric hopper roller (1) is installed at the bottom of the hopper (8), and the frame a force holding the P roller (+3) is connected to the reverse solenoid 05. It is rotatably provided around the bottle (1G). A pair of left and right reverse rollers αD facing the PR flora 13) at a predetermined distance are provided at the bottom of the hopper (8). Then, PR Flora lal, reverse solenoid (15) and frame I
and a reverse roller (17) constitute a reverse portion α mark.

Behind the reverse roller α force, paper feed rollers (1) and rollers (20) are arranged in the order of the conveyance path.
21 are joined. Also, there is a feed block t23) at the back of the hopper (7). The block arm (goods) to be held is held rotatably about the support shaft (26) ffi while being urged counterclockwise by the spring (25). The inner surface of this feed block (c) has a feed roller l.
An arc-shaped separation WIC1n is formed facing the outer circumferential surface of 19).

A feed block solenoid (marked 2) is connected to the lower end of the block arm (2), and the upper end faces a stopper (c) (30). The crawler 0yu and the roller (20) are each connected to a motor 0υ to rotate counterclockwise.The paper feed roller a9
The paper feeding section C'321 is composed of the roller (20), the feeding block I23), and the feeding block solenoid (c). The peripheral speed of roller I201 is paper feed roller q
The circumferential speed of 1 is also faster. Furthermore, the lower guide 01) is provided with a sensor example.

Next, the effect will be explained. Nine pieces of paper stacked in hopper (8)/
The third portion is sent to the left as if being struck by the eccentric hopper roller 03. In this case, since the first floor of the PR Flora is far from the reverse roller θ'7), the +3 pieces of paper are sent while slipping against the reverse roller (lη). When excited, it rotates clockwise and comes into contact with the stopper (c), and the separation surface 0'i) approaches the feed roller 09. This gap is narrow, and in this gap paper piece C3

and return it to the hopper (8).

Between the separation surface (27) and the outer periphery of the feed 90-ra αω, the friction between the feed roller and the piece of paper 04) is the largest, the friction between the separation surface (2η) and the piece of paper (goods) is the second largest, and the friction between the separation surface (2η) and the piece of paper (goods) is the largest The relationship between the paper strip (34) and the separating surface (2η and the feed roller 09) is determined to be the minimum.
are separated one by one.

However, as shown in Fig. 3, in the conventional feed block (27), the separation surface (2η) faces the entire width of the feed roller θ, so there is a gap between the feed roller 0 and the separation surface (2'0). It is difficult to set the paper pieces (34J) equally on the left and right sides, and the separability of the paper pieces (34J) is poor, which also causes the paper pieces (34) to meander during conveyance.

Purpose of the Invention The present invention has been made in view of the above-mentioned points, and it is possible to adjust the gap between the feed roller and the separating surface of the feed block equally on the left and right sides, to improve the separation of the paper pieces, and to prevent the paper pieces from meandering during conveyance. A piece of hanging paper■゛It is intended for several scales.

Summary of the Invention This invention provides a plurality of feed blocks arranged side by side along the axis of a feed roller, and the positions of these feed blocks are individually adjusted by stoppers, so that the feed blocks and the feed 90 can be adjusted.
- Make the gap between the left and right sides equal, so that 1 piece of paper
In order to improve the paper strips and prevent meandering of the paper strips, a recess is formed in the opposing part of the adjacent feed block, and an auxiliary roller is provided in the recess to press the paper strips against the feed roller. The block is moved away from the feed roller, and in conjunction with this operation, the auxiliary roller is also moved away from the feed roller to maintain a state in which paper pieces remaining on the inner surface of the feed block are returned to the hopper side.

Embodiment of the Invention An embodiment of the invention will be described with reference to FIGS. 4 to 7. Components that are the same as those described in FIGS. 1 and 2 are designated by the same reference numerals, and description thereof will be omitted. A pair of left and right block arms driven by a feed block solenoid (28) are rotatably held on the support shaft (26) and biased counterclockwise by a spring (25). Three feed blocks are screwed to the inner surfaces of these block arms (24), respectively.

There is a separation surface (27) on the inner surface of these feed blocks (3→
is formed.

Four parts (36) are formed along the outer periphery of the feed roller (I) on the opposing sides of the feed blocks C351 adjacent to each other on the left and right sides. A plate (37) is screwed and this support plate (3
7) has a protruding piece 09) extending upward to hold the bottle (38) and two bottles (40) in the recess (36).
A lever (41) rotatably held by these bottles (40) and (41) is formed to hold the protrusion (41). In addition, the lever (44) is biased in one direction by tensioning a spring (47) between its upper end and the bottle (C), and thereby the auxiliary roller (44) is biased in one direction. One (
4G) is the feed roller u! J is being aggressively contacted.

Next, a lever (43 (4)
4), which is a release body, is installed horizontally, and the feed roller (block arm Cl4 whose axis is parallel to the bar) has a rotation range in the direction 11. A book stopper (49) is placed horizontally on the same axis.As shown in Fig. 7, it is held by a bar (marked 4 is the opposing frame GO).The stopper (
49) whose outer ends are oaked to frame 6) ('
It is fixed by 1llll. At the inner end of the right stopper (49), a shaft portion that coincides with the axis is erected, and this shaft t5z is rotatable in a hole t53) formed at the inner end of the left stopper (49). is mated to. Furthermore, the stopper (49) has a hexagonal outer periphery for easy rotation, and an eccentric shaft 64) supporting the first grade of the upper part of the block arm C24 on the side of the feed roller A is formed in a part of the stopper (49).

In this configuration, when counting paper pieces (34), the feed block solenoid mark is energized and the block arm 124) is brought close to the feed roller hand together with the six e feed blocks, but the feed block (351) is Since it is divided into left and right parts, by loosening the nut 6υ and turning the stopper (19) and changing the contact surface of the eccentric shaft 4I with respect to the block arm (24J), the separation surface c can be set for each of the left and right feed blocks C3b. The gap between !D and the feed roller 00 can be adjusted. Therefore, this gap can be made equal on both sides in the width direction of the feed roller 0ω. Therefore, the paper piece Oa fed from the hopper (8) is reliably separated between the feed shear roller 0 field and the separation surface (27).Since the gaps are equal on the left and right sides, meandering of the paper piece (34) is also prevented.

In addition, since a recess (3611) is formed in the opposing part of the feed 9 block (g), even if the gap between the feed block (35) and the feed roller eel is slightly different on the left and right sides, the presence of the recess (36) allows them to be adjacent to each other. There is no difference in level between the opposing parts of the feed block (c).Also, in the fourth part (to), the paper piece 04 is moved by the auxiliary roller (a (46)) to the feed roller (p) (10).
You can prevent it from floating by holding it down. In particular, the feed roller 01 on the entrance side of the feed 9 block C35) is
) and smoothly introduce the paper piece 04 into the gap between the three feed blocks and the feed roller 0■. After counting the pieces of paper, the feed block solenoid (c)'i is turned OFF to move the block arm (24) along with the feed 9 block 09 away from the feed roller haze, but at this time the lever (4 moat (
4→ is a bar (spring (47) to interfere with 4EO
The auxiliary rollers (45, 46) can be rotated against the force of the feed roller (2) to separate them from the feed roller (2). In other words, it is possible to maintain a state in which the reverse renoids OQ are energized and the PR roller 0 is brought into contact with the reverse roller 07) so that the paper pieces C3l) after the preset number are returned to the hopper (8).

Effects of the Invention In this invention, as described above, a plurality of feed blocks are arranged side by side along the axis of the feed roller, and the positions of these feed blocks are individually adjusted by stoppers to adjust the position of the feed roller and the feed block. This makes it possible to make the gaps between the left and right sides equal, thereby increasing the separation of the paper pieces and preventing the paper pieces from meandering. Furthermore, after counting the pieces of paper, the feed block is separated from the feed roller, but at this time, the release body causes the p auxiliary roller to move away from the roller at full speed, and the inner surface of the feed roller is pressed. This has effects such as being able to maintain the state in which paper pieces remaining in the hopper are returned to the hopper side.
