Description

  The present invention relates to a paper sheet bundle bundling apparatus for bundling paper sheet bundles such as securities.

  The sheet bundle bundling apparatus is configured to collect and bundle five or ten 100 sheet bundles obtained by bundling paper sheets such as securities for every 100 sheets with a paper band or the like.

  Conventionally, this type of bundling device is used integrally with a paper sheet stacking device that sorts paper sheets into a regular ticket, a non-performing ticket, or a rejection ticket, or as a post-processing device for a paper sheet processing device. The

  In the former case, the paper sheets that have been classified into the correct paper and the non-payment paper by the paper sheet processing device are collected and bundled by a paper band by the bundling device every time 100 sheets are formed to form a bundle of 100 sheets. Discharged. The bundle of 100 sheets discharged in this way is conveyed by a conveyor and stacked into 5 or 10 sheets to form 500 sheet sheets or 1000 sheet sheets, and then further bundled by a sheet sheet bundling device, A bundle of 500 sheets or 1000 sheets is formed.

  Hereinafter, a case where five 100-sheet bundles are stacked and bound will be described. Conventionally, in order to bind 500 sheets of paper in which five 100-sheet bundles are stacked, they are bound by the following procedure. This will be described below with reference to FIGS.

(1) The stacked 500 sheets are pushed out by the pusher 150 and conveyed on the conveying path in the direction of the arrow A (FIGS. 9 and 10).

(2) When 500 sheets of paper reach a predetermined binding position, extrusion by the pusher is stopped (FIG. 11).

(3) The sheets are bound by the binding band K2 at the binding position by the paper sheet binding apparatus. Note that a cutout portion (band discharge groove) 140 is provided in a portion where the binding position contacts the conveyance surface, and 500 sheets are bundled by a binding band K2 passing through the band discharge groove 140. Is formed.

  At this time, the lowermost sheet P1 of the 500 sheets may hang down from the belt discharge groove 140 and bend and turn over as the 500 sheets are pushed out (see FIG. 10).

  In order to prevent this turning, conventionally, an elastic member disposed at a predetermined angle toward the downstream in the transport direction upstream of the discharge groove 140 immediately upstream in the transport direction so that the lowermost paper sheet does not enter the belt discharge groove. A leaf spring constituted by a body is arranged, and when the 500 sheets are conveyed, the bottom sheet is lifted so as not to enter the belt discharge groove 140, and the 500 sheets are predetermined. When the sheet is pushed out to the bundling position, the 130 is pushed down to the conveying surface by the load of the 500 sheets. Paper sheet bundling apparatuses and paper sheet bundling methods are known (see, for example, Patent Document 1).

JP 2007-91302 A (page 4-5, FIG. 1)

  However, in the jump stand system using the leaf spring described above, it is necessary that the leaf spring is pushed down to the conveying surface which is the lowermost surface when 500 sheets arrive at a predetermined binding position. The band is tightened after the binding band K2 is rotated around the outer periphery of the 500 sheets in this pressed state, and the binding band is sandwiched from the front and back of the binding band at the position on the transport surface of the band discharge groove and thermally bonded. Because there is a need, it is preferable that the bonding position is always a constant place. It is also possible to perform the thermal bonding of the cable tie on the top surface side of the 500 sheets of paper, but the thickness of the correct and non-performing sheets of the 500 sheets of paper varies up to about twice. This is because the thermal bonding position is not constant, and complicated processing is often required as compared with the case of bonding on the lowermost surface described above.

  Therefore, the spring force of the leaf spring is strong, and when 500 sheets are lifted at a predetermined binding position, there is a gap between the heat bonding position and the bottom sheet of the 500 sheets. As a result, a bundle of 500 loose bands is formed. Further, when the spring force of the leaf spring is weak, there is a problem in that a 500-sheet bundle is formed in which the paper sheets on which the lowermost paper sheets hang down before the 500-sheet paper sheets reach a predetermined position. there were. In addition, since the size of the paper sheet to be handled varies depending on the ticket type, the weight varies in the state in which 500 sheets are formed. Even when these weight fluctuations occur, it has been a problem to uniformly bind using the above-described leaf spring.

  SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In a sheet bundle bundling apparatus that feeds and bundles stacked 500 sheets to a predetermined bundling position, the bottom sheet is prevented from being turned over. An object of the present invention is to provide a paper sheet bundling apparatus having a mechanism.

In order to achieve the above object, a sheet bundle bundling apparatus according to claim 1 of the present invention comprises a predetermined number of first sheet bundles formed by bundling a predetermined number of sheets with a first bundling band. A sheet bundle bundling device that stacks and conveys and further bundles with a second bundling band to form a second sheet bundle, and is upstream of conveyance for conveying the predetermined number of first sheet bundles.

  The paper sheet bundle bundling apparatus of the present invention is incorporated into a paper sheet processing apparatus and used as a unit. Alternatively, as a post-processing device for a paper sheet processing apparatus, a stack of five or ten sheets of 100 sheets discharged from the paper sheet processing apparatus is conveyed at a binding position of the paper sheet binding apparatus. Convey or send out and bind at the paper sheet bundle binding position. Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view illustrating a configuration of a sheet bundle binding device 1 according to an embodiment of the present invention, and is a diagram illustrating a state in which 500 sheets are placed.

  The sheet bundle bundling apparatus 1 includes five 100 sheet bundles (first sheet bundles) formed by bundling a predetermined number (for example, 100 sheets) of paper sheets with a paper band (first bundle band). Two transport bases 20a, 20b, a leaf spring (elastic body) 30, a groove closing plate 10, a shutter 12, a sensor (detection means) 13, and a belt, which are separately disposed to transport the 500 sheets of laminated paper. It has a winding machine 6 and a pusher.

  The transport base 20a disposed on the upstream side of the transport and the transport base 20b disposed on the downstream side of the transport are spaces in which the binding band (second binding band) according to the present embodiment can be wound. A belt discharge groove 40 is provided and disposed.

  An inverted “he” -shaped leaf spring 30 is disposed at the end of the transport upstream transport base 20a, which is immediately upstream of the belt discharge groove 40. The leaf spring 30 is made of a resilient material (for example, SUS304CPS-H), and is disposed at an angle of 15 degrees toward the end of the transport base 20a.

  The groove closing plate 10 is fixed to the L-shaped support material 11 and is incorporated in the shutter 12.

  The support member 11 is incorporated in the shutter 12 and has a contact surface that comes into contact with the end surface on the front end side of a 500 sheet sheet pushed out by a pusher described later. A 500 sheet sheet is provided by a spring material provided on the shutter 12. It is urged so as to protrude in the direction opposite to the conveying direction of the lens, and is in a position protruding from the opening provided in the shutter 12. However, when 500 sheets are pushed out by the pusher and the front end side end face of the 500 sheets pushes the contact surface of the support member 11 in the carrying direction, the support member 11 is pushed out in the carrying direction. fall back.

  The shutter 12 is configured to be movable back and forth in a direction orthogonal to the transport direction. When the shutter 12 is advanced (shutter closed), it can stop the transport of 500 sheets on the transport base 20b and perform the bundling process. When exiting (shutter opening), the bundled 500 sheets S can be further transported in the transport direction.

  In addition, since the shutter 12 incorporates the support member 11 described above, the support member and the groove closing plate 10 fixed to the support member in the forward / backward movement direction of the shutter 12 also move in the forward / backward movement direction of the shutter 12. Moving.

  FIG. 2 is a diagram illustrating a flow until the paper sheet bundle S is bundled by the paper sheet bundle binding apparatus 1 according to the present invention. This will be described below with reference to these drawings.

  A bundle of 100 sheets H formed by a paper sheet processing apparatus (not shown) is conveyed by the belt conveyor 2 in the direction indicated by the arrow B1. The transported 100-sheet bundle H is discharged from the end of the belt conveyor 2, transported in the direction of the arrow B2 in the figure, and stacked on the lifter 3 (FIG. 2 (1)).

  When the 100-sheet bundle H stacked on the lifter 3 reaches 5 pieces and becomes 500 sheets in this way, the lifter descends in the direction of the arrow B3 and reaches a predetermined position (FIG. 2 (3)).

  The 500 sheets that have reached the predetermined position are delivered from the lifter 3 to the carrier 4. The lifter 3 rises and returns to receive the next 100-sheet bundle.

  The 500 sheets placed on the carrier 4 are pushed in the direction indicated by the arrow B4 by the pusher 50 (FIG. 2 (4)) and supplied to the sheet bundle binding apparatus 1 (FIG. 2 (5)).

  When the 500 sheets supplied to the sheet bundle binding apparatus 1 are further pushed by the pusher 50 and reach a predetermined position, the sensor (detection means) 13 detects that the sheet has reached a predetermined position, and 500 sheets. The paper sheets are bound by a binding band K2 to form a bundle of 500 sheets.

  The 500-sheet bundle S thus formed is discharged from the paper sheet bundle binding device 1 by the pusher 5 (FIG. 2 (5)).

  FIG. 3 is a perspective view of the sheet bundle binding device 1 in a state where the 500 sheets shown in FIG. 1 are pushed out to the binding position. When the 500 sheets are pushed forward by the pusher from the rear end in the transport direction, the leading end of the 500 sheets is blocked by the shutter 12 while pushing the protruding portion of the groove closing plate 10 and stopped. This is a state in which 500 sheets have reached a predetermined binding position.

  FIG. 4 is a perspective view of the sheet bundle bundling apparatus 1 showing a state where the shutter 12 is opened after the 500 sheets shown in FIG. When the leading end of the 500 sheets reaches a predetermined binding position in contact with the shutter 12, the groove closing plate 10 is pushed out based on that and the band discharge groove 40 is opened. When the sensor 13 detects that the 500 sheets have been pushed out to the position of the shutter 12, the binding band K2 is released and wound around the 500 sheets, and after being banded, it is thermally bonded. A sheet bundle S is formed.

  Thereafter, the shutter 12 is opened and the traveling direction of the 500-sheet bundle S is released, and the sheet is further pushed out on the transport base 20 and discharged from the sheet bundle binding apparatus 1.

  FIG. 5 is a perspective view of the sheet bundle binding device 1 showing a state in which the 500 sheet bundle S shown in FIG. 4 is sent to the next process and returned to the initial state.

  In this state, the opened shutter 12 is closed. Further, the groove closing plate 10 incorporated in the shutter 12 protrudes from the front surface of the shutter 12 and returns to the spring force of the spring attached to the rear surface of the shutter 12. The figure shows this restored state.

  FIG. 6 is a side view for explaining the operation of the sheet bundle bundling apparatus according to the embodiment of the present invention, in which the tip of the 500 sheet bundle reaches the tip of the band discharge groove 40 and is lifted by the leaf spring 30. FIG. The 500 sheets are pushed in the direction indicated by the arrow B4 by the pusher 50.

  The pusher 50 is composed of an L-letter shaped plate-like body having a pressing portion that comes into contact with and presses the rear end surface of the 500 sheets and a bottom that comes into contact with the bottom of the 500 sheets. The 500 sheets are pushed out by the pusher 50 in a state where the rear end portion of the 500 sheets is placed on the bottom configured as described above, and conveyed in the B4 direction in the drawing.

  With such a configuration, when the bottom portion of the pusher 50 is not configured in an L character shape, it is possible to prevent the bottom sheet from being left on the transport base 20a due to friction with the transport base 20a. doing.

  When 500 sheets are transported in the direction of the arrow on the transport base 20a configured as described above, the leading edge of the 500 sheets is lifted by the leaf spring 30, and the bottom sheet is suspended. This prevents the belt discharge plate 10 from entering. Further, the support member 11 also protrudes from the shutter 12 in the direction opposite to the conveyance direction, and the upper surface of the conveyance base 20 of the band discharge groove 40 (generic name for the conveyance bases 20a and 20b) is closed by the groove closing plate 10 fixed to the tip thereof. It is done.

  As a result, the drooping of the lowermost sheet of the 500 sheets is prevented from entering the belt discharge groove 40.

  FIG. 7 is a view showing a state in which the 500 sheets shown in FIG. 6 are further pushed out and pass through the belt discharge groove 40 closed by the groove closing plate 10.

  The 500 sheets pushed out by the pusher 50 are pushed out in the direction of the arrow B4 in the drawing and are placed on the groove closing plate 10 while being moved, and the tip thereof reaches the support member 11. The figure shows the state where the support material 11 has been reached. In this state, it is preferable that the leaf spring 30 is pushed down by a load of 500 sheets of paper, and the tip thereof forms the same surface as the mounting surface of the support material 11. If the spring force of the leaf spring 30 is too strong, the leading edge of the 500 sheets is excessively raised, which is an obstacle to good binding when binding as described above. On the other hand, if the spring force is too weak, the tip of the 500 sheets cannot be lifted and the effect of the leaf spring 30 is reduced.

  FIG. 8 is a diagram showing a state where the 500 sheets shown in FIG. 7 are further pushed out, reach the binding position, and are bound. In FIG. 7, the 500 sheets placed on the groove closing plate 10 are further pushed in the transport direction by the pusher 50 and are sandwiched between the support member 11 and the pusher 50 urged by the spring material. It moves until it contacts the shutter 12. Accordingly, the support member 11 is pushed out along the conveyance direction of the 500 sheets of paper and is in a retracted state.

  A sensor (detection means) 13 detects that the end of the 500 sheet has reached the position of the shutter 12.

  The control unit (control unit) 6a is controlled by the CPU that controls the paper sheet bundling device 1, and when the detection unit detects that the support member 11 is in a predetermined position, the 500 sheets at that time Since the transport position of the kind is at the band winding position by the band winding machine 6, the band winding machine 6 is driven.

  Based on an instruction from the control means 6, the band winding machine 6 feeds the binding band (second binding band) K 2 from the band discharge groove 40 and binds the 500 sheets to form a 500 sheet bundle S. .

  As the support material 11 moves, the groove closing plate 10 also moves, and the band discharge groove 40 is opened. In this state, the band winding machine 6 winds the binding band K2 around the outer periphery of the 500 sheets of paper and binds the 500 sheets of paper to form a 500 sheet bundle S. The figure is exactly this state.

  As described above, according to the paper sheet bundling device of the present invention, it is possible to prevent the paper sheets from being turned up without the bottommost paper sheets of the 500 sheets of paper entering the belt discharge groove 40.

  The above-described leaf spring 30 is an example used when processing paper sheets according to the present embodiment, and is not limited to this, but in the present embodiment using the leaf spring 30 and the groove closing plate 11. By using such a configuration, even when the ticket type or size of the paper sheet is changed, it is possible to prevent the lowermost paper sheet of the paper sheet bundle from being conveyed and further bound. .
