Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet stack storage device for a sheet counting machine.

Conventionally, many paper sheet counters have been used that use a suction shaft that rotates and revolves around a bundle of paper sheets placed on a holder to pick up each sheet one by one and count the sheets while turning them over. There is. At this time, there are two methods: to place the stack of paper sheets on the holder, or to remove the stack of paper sheets from the holder after counting, either manually or automatically using a combination of devices. Each can be considered.

As in the former case, if the loading and unloading of paper bundles relies on manual labor, even if the counting process can be streamlined and the counting time shortened, manual operations will take time and increase the operating rate.

Note that there may be three or more sheet bundle storage sections, and these may be switched by an inclined gate plate.

In addition, in FIG. 4, a supplementary explanation will be given regarding a known configuration for turning over the sheet bundle S one by one. The holder 3 includes a mounting plate 76 that supports the paper bundle S in an upright state and is rotated about a rotation shaft 75, and the mounting plate 76 and the mounting plate 76 come into contact with one side of the paper stack S. A side plate 77, a paper abutment plate 78 disposed at the tip of the side plate 77 for contacting and positioning the tip of the paper bundle S supported by the mounting plate 76, and a paper abutment plate 78 that is integrally attached to this paper abutment plate 78 and for positioning the paper bundle S. A mounting table 79 slides and supports the tip of the paper sheet S as necessary, and a stack of paper sheets S supported by the mounting plate 76 is pressed against a side plate 77 to be rotated together with the side plate 77 while sandwiching the stack of paper sheets S. It is composed of a paper presser rod 80. In addition, in the rotation direction of the holder 3, a rotating cylinder 81 that revolves
is provided on the upper surface of this rotary cylinder 81, which contacts the stack of paper sheets S rotated to the counting position and picks up one paper sheet by the suction action of the suction surface 82 while rotating in the opposite direction to the revolution. A plurality of suction shafts 83 are provided for turning over each page one by one. Furthermore, in one embodiment, a through hole 84 is provided in a corresponding portion of the paper backing plate 78 of the holder 3 that intersects with the optical axes of the optical sensors 40A, 40B of the paper bundle delivery device 4.

The paper sheet counting machine configured in this manner performs the following operations.

First, as shown in FIG. 1, a large number of paper stacks S are loaded between the movable clamping plate 11 and the front plate 14 of the paper stack discharging device 1, and when the device is put into operation, a second
Power is transmitted through the friction clutch 19 shown in the figure, causing the chain 18 to rotate in the forward direction, causing the ejector block 17 connected to the chain 18 to rise, and the first block 17 pressed against the front plate 14 by the spring 13 to move forward. When the stack of paper sheets S is pushed up by the ejector rod 15 and the lower end of the stack of paper sheets S rises above the upper end of the front plate 14, the first bundle of paper sheets S is pushed up by the urging force of the spring 13 into the paper bundle discharge device 1. cradle 20 of the paper bundle supply device 2
The stack of paper sheets S is then dropped in an upright position. Further, although forward rotational power continues to be transmitted to the chain 18, the moving range of the ejector block 17 is limited and acts as a stopper, and the friction clutch 19 then slips, causing the ejector rod 15 to move as shown in FIGS. 1 and 2. The second sheet bundle S remains in the position shown by the chain line in the figure, and the second sheet bundle S is supported in contact with the ejector rod 15.

Further, in one embodiment, the sheet bundle supply device 2 and the sheet bundle discharge device 1 are operated by a common drive source, so that when forward rotation is transmitted from the drive source to the belt pulley 28, the chain 29 The support block 22 and the pedestal 20 gradually begin to descend, and the stack of paper sheets S is placed on the pedestal 20 at a slightly lowered position. Next, the pedestal 20 is placed on the mounting base 76 of the holder 3.
The operation plate 27 hits the stopper to restrict the downward movement of the support roller 26, and when the support roller 26 comes off the support plate 20, the support roller 26 moves downward.
0 is rotatable, and the paper bundle S is dropped onto the mounting plate 76 of the holder 3 by its own weight. Furthermore, when the support block 22 is lowered, the micro switch 30B shown in FIG. The chains 29 of the feeding device 2 are each moved in opposite directions. Therefore, the ejector bar 15 is gradually lowered and returned to its original position, and as the ejector bar 15 is recessed from the upper plate 10, the second sheet bundle S is moved by the spring 13.
When the push-out block 17 is lowered to a predetermined position and its movement is restricted, the friction clutch 19 slides in the opposite direction and is on standby. do.
On the other hand, when the pedestal 20, support block 22, etc. rise and the operation plate 27 leaves the stopper, the support roller 26 is returned by the spring 25 as shown in FIG. 3B, and the pedestal 20 is leveled again. When the support block 22 returns to the upper limit, the micro switch 30A operates to cut off the drive source and transmit the power to the sheet bundle discharge device 1 and the sheet bundle supply device 2. It will no longer be displayed and will return to its original state.

Next, processing of the bundle S of sheets dropped into the holder 3 will be explained. FIG. 4 shows the state of the holder 3 and the sheet bundle delivery device 4 before operation. When a sheet bundle S is dropped onto the holder 3 as shown by the chain line, the detection plate 31 moves due to its own weight. A signal is output from the paper bundle detection switch 32, and this detection signal excites the solenoid 33, causing the connecting arm 35 to rotate counterclockwise in Figure 4 and the push plate 39 to rotate clockwise in Figure 4. The stack of paper sheets S on the mounting plate 76 is pushed in the direction of arrow A, and the leading end is brought into contact with the paper cover plate 78 for positioning. When the leading edge of the paper bundle S intersects the optical axis of the optical sensors 40A, 40B, a signal is output from the optical sensors 40A, 40B, and the side plate 77 is rotated in the direction of the rotary cylinder 81 by known means. The paper stack S is held between the paper pressing rod 80 and the side plate 77, and the paper stack S comes into contact with the suction shaft 83, causing the revolving action of the rotary cylinder 81, the rotation action of the suction shaft 83, and the depressurization of the suction surface 82. The paper sheets are turned over one by one by a known action such as suction action (vacuum) and counted.

When this counting is completed, if there is no abnormality in the counting result, a seal is stamped on the banding part of the sheet bundle S, and regardless of whether the counting result is normal or abnormal, the holder 3 is moved to the holder 3 as shown in the solid line in Fig. 4 by the completion signal. At the same time, the drive source 41 is operated, and the rotational force is transmitted to the connecting pulley 44 by the pulley 42 and belt 43, and the feeding roller is rotated through the rotating belt 48 of the connecting pulley 44. 49 for continuous rotation, and the rotation of the connecting pulley 44 is also transmitted to the swing arm 47 via the friction clutch 46. Therefore, the swinging arm 47 rotates in the direction of contacting the stack of paper sheets S, and its swinging is restricted by contact with the rotating feed roller 49 at its tip, causing the friction clutch 46 to slip. While pressing the stack of paper sheets S. Due to the rotational force of the feed roller 49, the sheet bundle S is fed out toward the base end of the holder 3 and toward the sheet bundle sorting device 5. The feeding operation at this time is performed in parallel with the operation of returning the holder 3 to its initial position (the position shown by the solid line in FIG. 4). is rolled out. Next, when the optical sensors 56A and 56B detect the passage of the paper bundle S, the drive source 41 is cut off by this detection signal, and the drive source 41 is subsequently operated in reverse rotation, and the swing arm 47 is rotated to the second position. It is rotated back in the direction opposite to arrow B in FIG. 4, and this rotation continues until the swing arm 47 operates the micro switch 55 and shuts off the drive source 41.

Furthermore, the operation of the paper bundle discharge device 1 is restarted by the operation of the microswitch 55.

In addition, in the sheet bundle sorting device 5, the gate plates 60A and 60B are switched depending on whether or not there is an abnormality in the sheet bundle S fed out from the sheet bundle sending device 4, and the gate plates 60A and 60B are switched to move the sheet in the desired direction. The leaf bundle S is made to fall. That is, if an abnormality is detected in the stack of paper sheets S supported by the holder 3, such as an excess or deficiency in the number of sheets, damage, or a mixture of different sizes, the stack of paper sheets S is , the solenoid 65 is excited by the abnormality detection signal, and this driving force causes the operation link 67 to move to the right in FIG. 6 against the biasing force of the restoring spring 69, and the gate plates 60A and 60B It is switched as shown by the solid line in Figure 6. In FIG. 6, the gate plate 60A
is inclined, and when an abnormal paper stack is dropped from the paper stack delivery device 4 onto this gate plate 60A, the abnormal paper stack S is sorted in the desired direction along the inclined surface of the gate plate 60A. It will be dropped. Further, the optical sensors 56A and 56B are connected to the paper bundle S.
After detecting the passage of
2 seconds, the time it takes for the paper bundle S to be dropped onto the gate plates 60A, 60B), the excitation of the solenoid 65 is interrupted, and then the operating link 67 is moved to the left in FIG. The gate plate 60B is switched to an inclined state and the gate plate 60A is switched to a vertical state, respectively, and the normal sheet bundle S is returned to the state where it is guided to fall by the gate plate 60B. Both gate plates 60A, 60
It is best to make elastic contact with the tip of B so that no gap is formed in the contact area, and the gate plate 60
A and 60B are made of elastically deformable material, or
Alternatively, a method may be implemented in which the pin 63 is biased to deepen the contact so as to have a slight play around the pin 63.

Next, the paper bundle S sorted and dropped into the paper bundle storage device 6 is transferred from one of the openings 71 and 72 to the abnormal banknote storage section 7 separated by the partition plate 70.
3 or into the normal banknote storage section 74, where they are sorted and stored as normal or abnormal banknotes.

These series of operations for processing the paper stack S are repeated every time the paper stack S is discharged from the paper stack discharging device 1. Even if the bundle discharging device 1 becomes “empty” and its detection signal is output, or the operation of the drive source is transmitted to the sheet bundle discharging device 1 and the sheet bundle supplying device 2 and a required period of time has elapsed. This process is automatically performed until the entire apparatus is stopped due to a phenomenon such as when the paper stack S is not detected by the paper stack detection switch 32.

In one embodiment, a feeding roller 49 is provided at the tip of the swinging arm 47 as shown in FIG. The feeding roller is protruded, and the swing arm 47 moves the sheet bundle S.
It is also possible to make it come into contact with a feeding roller and feed it out.

As explained above, according to the present invention, the storage box is located above the normal paper stack storage section and the abnormal paper stack storage section in the storage box partitioned by the partition plate, and the Horizontal support shafts are provided at positions horizontally apart from the surface, spaced apart from each other, and parallel to each other.Furthermore, each lower side is swingably supported on these horizontal support shafts, and the upper sides are supported on these horizontal support shafts. Since a pair of gate plates are provided in contact with each other, by setting the horizontal support shaft on which the lower sides of the pair of gate plates are supported at a distance in the horizontal direction from the plate surface of the partition plate, these gate plates can be It is possible to set the inclination angle of the partition plate to a relatively gentle angle, and it is possible to distribute paper sheets that have fallen from above the partition plate to the normal paper stack storage section or the abnormal paper stack storage section of the storage box. In this case, by sliding the gate plate, these paper bundles can be dropped into the normal paper stack storage section or the abnormal paper stack storage section at a relatively gentle slope, and the paper sheets can be removed. This has the effect that it is possible to prevent the end face of the leaf bundle from being directly damaged, and that the paper leaf bundle can be aligned and stacked horizontally.

In addition, the normal paper stack storage section and the abnormal paper stack storage section in the storage box are configured to be removable from the main body of the paper sheet counter, so that they can be removed after distributing the paper stacks. The paper stacks stored in the normal paper stack storage section and the abnormal paper stack storage section can be easily taken out, which has the effect of improving work efficiency.
