Abstract

A sheet conveying apparatus comprises a conveying passage composed of upper and lower guide plates adapted to define a conveying path, along which sheets or the like are conveyed in a specified direction, and a sidewise-moving mechanism for moving bills on the conveying passage in a direction perpendicular to a conveying direction. The sheet conveying apparatus further comprises a feeding mechanism provided at the substantial middle of the conveying passage in a widthwise direction for feeding sheets or the like in the conveying direction, and a sidewise-moving mechanism arranged near the feeding mechanism in a widthwise direction for moving bills to one side in a widthwise direction. When the sidewise-moving mechanism projects over the conveying passage in order to move bills in a widthwise direction, the feeding mechanism withdraws from the conveying passage. Accordingly, it is possible to improve a sidewise-moving capacity and further shorten a processing time without making the apparatus complicated in constitution and increasing costs.

Width adjustment mechanism in paper sheet transport device

The present invention relates to an improvement in a sheet handling apparatus provided with a transfer device for feeding received sheets into the apparatus, such as a vending machine, a money changing machine, a copying machine, a printing machine, and the like. The present invention relates to an improvement in an automatic width-shifting device in which a sheet having a smaller width than the width is conveyed while being converged on one side wall of a conveyance path. Technology background

Devices such as vending machines, currency exchange machines, copiers, printing machines, etc., which have a mechanism for receiving bills such as banknotes and paper (sheet handling devices), each of these sheets A transport device is provided for guiding the type to a true identification unit, a printing unit, and the like. By the way, when paper is manually inserted into these paper handling devices, the force that pushes the short side of the paper toward the top into the transport path extending from the insertion slot to the inside. The width of the entrance (conveyance path) is often set to be large according to the maximum width of paper so that all paper of different widths can be accepted. In this case, if you try to insert narrow paper sheets based on the center, there is no guide means to regulate the width direction of the paper sheets. It will be easier.

This point will be described in more detail using a bill handling device such as a vending machine as an example. Since a bill normally has a different size (especially the length of a short side) depending on a denomination, etc., the width of a bill 揷 entrance and a transport path are not accepted. It is designed to be large according to the maximum width of banknotes that assume However, if narrow banknotes are to be transported on a wide transport path with a central reference (a method of aligning the widthwise central portion of the transport path with the central portion of the banknote width direction), the banknotes can move freely in the width direction. At the time of reaching the Jiangjiang identification section, it is shifted from the transport reference position, and skew and jam are likely to occur. As a result, indistinguishability, erroneous identification, or deterioration of alignment at the time of delivery to a safe located at the latter stage of the identification unit occurs. Also, if skew occurs in a copying machine, etc., it may cause printing defects and jams. As a means of solving such a problem, a method of instructing that paper sheets should be inserted toward one side of the entrance, for example, the left end, by a display label or the like provided near the insertion port of the paper sheet handling apparatus. However, this method has a disadvantage that the ratio of insertion position depends on the user is too high. As a result, not all people will see the displayed instructions and insert them correctly, making them unusable, especially for children or blind people who cannot read. In addition, the user does not always always insert the product straight as directed, but if it is inserted in a slightly skewed state, the situation may occur without correction.

Next, FIGS. 5A and 5B are a plan view and a cross-sectional view showing a configuration of another conventional example. This conventional apparatus has a mechanism for shifting a sheet to one side in the width direction. I have. That is, side plates 2 and 3 are provided upright on both sides in the width direction of the transport path 1, and the width adjusting roller 4 is inclined at a predetermined angle with respect to the transport direction at a position closer to one side than the center of the transport path 1. It is arranged. The transport path 1 is formed between the upper guide plate 5 and the lower guide plate 6, and the width-adjusting roller 4 partially projects from the notch 6a formed in the lower guide plate 6 into the transport path. ing.

In this device, the inserted banknote P is nibbled between the width-adjusting roller 4 and the upper guide plate 5 and the banknote is shifted toward the left side plate 2, and the banknote P is moved by the force between the side plate 2 and the banknote. This is to correct the direction of the bill parallel to the transport direction. The photo sensor 7 detects that the bill has shifted to the position of the chain line.

However, this device has the following disadvantages. In other words, the conveying force for the waist line having a wrinkle or a kinking fragile waist is weak, and it is difficult to draw in the inside by the width pulling roller 4, and even if the pulling is performed, the width cannot be pulled. In addition, the ability to pull the width of the bank is weak, and it is difficult to correct the posture of the inserted banknote in the same direction as the width-roller while correcting the orientation of the banknote in parallel with the transport direction. Also, since the customer starts to pull in the diagonal direction from the point when the customer inserts the bill into the entrance, the customer's holding power of the bill becomes an obstacle to width adjustment until the customer releases the rear end of the bill. , The ability to approach is reduced.

Next, FIG. 6 shows another conventional example, in which the apparatus is positioned vertically above and below a transport path. It has first and second belts 10 and 11 that are arranged separately, and width-adjusting rollers 12 and 13 that are also arranged at upper and lower positions across the transport path, respectively, and transports paper sheets. When sending in the direction, the two belts 10 and 11 are brought close to each other as in (1)) and transported at the contact part of both belts. At this time, the upper and lower width adjustment rollers 12 and 13 are separated from each other. When the paper is sent to the home position by the belt, as shown in (c), the two belts are separated in the vertical direction, and the width-adjusting rollers 12 and 13 which were in the separated state until then are fed by the paper And send it in the width direction. When a sensor (not shown) detects that the paper sheet has approached one of the side walls 2, the belt and the width adjustment roller are returned to the state of (b) again, and the paper sheet is conveyed in the depth direction. The vertical movement of the belt and roller is performed using a solenoid, for example.

However, the above-mentioned device requires a complicated and expensive mechanism because it needs to nip the width adjusting roller while lifting the belt. Furthermore, after the banknotes reach the above-mentioned fixed position, it is necessary to take steps such as turning on the solenoid, rotating the motor for driving the width-adjusting roller, detecting the width-adjustment, turning off the solenoid, and driving the conveyor belt. Become slow.

FIG. 2 is a sectional view taken along the line AA of FIG. — Section B, Fig. 4 (a) and 3B and 3B are a perspective bottom view and a perspective view of an eccentric roller, respectively, showing a configuration of a main part of the width shifting device.

The width-adjusting device 20 is applied to a paper-sheet handling device having a structure for transporting inserted paper sheets in a certain direction and guiding them into the apparatus to identify the paper sheets. Here, the paper sheet handling device includes, specifically, a transport path for receiving bills, an identification unit for identifying a denomination of a bill sent through the transport path, true) g, and the like. Equipment such as vending machines and currency exchange machines is assumed. It is also assumed that a copying machine or a printing machine has a transport path for receiving recording paper fed manually or the like and an image forming section (printing section) for forming an image on the recording paper fed through the transport path. ing.

As shown in FIG. 1, FIG. 2, and FIG. 3, the width shifting device 20 of the present invention includes a conveying path 2 formed between an upper guide 21 and a lower guide 22 which are arranged substantially parallel to each other. 3, a feed mechanism 24 provided near the center in the width direction of the transport path 23 to feed the sheets P in the transport direction C, and a direction orthogonal to the transport direction C for the banknotes P in the transport path 23. And a width shifting mechanism 25 for shifting the width.

The feed mechanism 24 receives the banknote P inserted into the transport path 23, transports the banknote P to a predetermined position, and stops transporting the banknote when the banknote P reaches the predetermined position. While the feeding mechanism 24 is being driven, the width shifting mechanism 25 is moved when the force feeding mechanism 24 retreating downward from the opening provided in the lower guide 22 stops the bill at the predetermined position. However, it protrudes on the transport path and comes into contact with the bill, and starts transporting in the width direction. The feed mechanism retracts downward from the transport path in conjunction with the operation of the width shifting mechanism projecting onto the transport path.

Hereinafter, the configuration of the device of the present invention will be described in detail.

The feed mechanism 24 projects a part of the outer peripheral surface into the conveyance path from an opening 22 a provided at the center in the width direction of the lower guide 22 constituting the conveyance path 23, or retracts the conveyance path downward. And a plurality of feed rollers 30 supported so as to be able to move paper money between the feed rollers when the feed rollers 30 are in the raised position as shown in FIG. A feed belt 31 (round belt) to be fed and a rotatable support point 32 located at one end in the width direction for supporting the feed roller 30 rotatably and movably supported by a bill handling device. Frame 3 3 and the fulcrum 3 2 And a cam follower 35 rotatably supported at the other end of the frame 33 in the width direction. The round belt 31 does not nib with the feed roller 30 and is located between the rollers arranged at a predetermined interval in the axial direction, and grips the bill between the two. In addition, the eccentric roller 42, as shown in FIG. 4 (b), fits a 0-ring 42A made of a material having a certain frictional resistance into a recess provided on the outer periphery of the roller, thereby friction with the bill. They try to get resistance.

The width shifting mechanism 25 is driven to rotate by receiving a driving force from an output shaft of the width adjusting motor 40 supported on the bill handling device main body side and an output shaft of the motor via a timing belt 41 or the like. An eccentric roller 42, a cam 43 receiving the driving force of the width shifting motor 40 via a timing belt 41 and having the cam follower 35 rollably contact the outer peripheral surface thereof; In order to allow a part of the outer peripheral surface of the roller 42 to protrude upward beyond the transport path 23, the roller 42 has a recess 21a formed in the upper guide 21 of the transport path. The eccentric roller 42 is configured so that a part of the outer peripheral surface can protrude from the opening 22b provided in the lower guide 23 toward the conveyance path, and when it protrudes as shown in FIG. It operates to nib a part of the banknote P between the recess 21a and the width in the width direction (left side in Fig. 1). Completion of the width adjustment may be detected by a not-illustrated photointerior provided in the conveyance path 23 or the like.

The cam 43 has a substantially heart shape having a convex portion 43a and a concave portion 43b on its outer peripheral surface, and the concave portion 43b contacts the cam follower 35 as shown in FIG. The eccentric roller 42 is retracted from the transport path because the portion of the outer peripheral surface of the eccentric roller 42 remote from the eccentric shaft 42a is located on the transport path side, and the feed mechanism including the frame is in the ascending position. Is held. Also, as shown in FIG. 1 (b), when the convex portion 43a is in contact with the cam follower 35, a portion of the outer peripheral surface of the eccentric roller far from the eccentric shaft 42a projects into the transport path. Since the convex portion 43 a pushes down the feed mechanism including the cam follower downward, the eccentric roller 42 protrudes into the transport path, and the feed mechanism including the frame retracts downward against the panel 32.

The width adjusting device of the present invention having the above-described configuration, the inserted bill is fed by the feeding mechanism. After feeding to the predetermined position in the conveyance direction, the width is adjusted by the width adjustment mechanism in the direction perpendicular to the conveyance direction.When the feeding mechanism is operating, the width adjustment mechanism is retracted from the conveyance path, and Since the feed mechanism is configured to retract from the transport path when the width adjustment mechanism is operating, the width adjustment ability can be increased and the speed can be increased. In addition, the movement of each mechanism forward and backward from the transport path is interlocked with each other, and is realized by a simple mechanism centered on a cam. Therefore, it is possible to prevent the device configuration from becoming complicated, large, and costly. . Industrial applicability

As described above, according to the present invention, it is possible to improve the wrap-around capability and further reduce the processing time without complicating the configuration of the device or increasing the cost.
