Description

  The present invention relates to an exclusion ticket stacking apparatus for a paper sheet processing apparatus that processes paper sheets such as securities.

  A paper sheet processing apparatus for processing paper sheets such as securities takes out and transports the paper sheets that are put in a batch one by one, and the quality (shape, shape, Inspect for damage, faint prints, stains, etc., and categorize it into normal tickets (hereinafter referred to as regular paper), defective tickets (hereinafter referred to as waste paper), and rejected tickets such as abnormally transported tickets and double-sheet pickup tickets. It is a device for processing. Regular paper is bundled with a paper band every 100 sheets to form a bundle, and if necessary, 10 bundles are stacked and further bundled with a paper band to form a bundle.

  When this kind of paper sheet processing apparatus is used in an issuing place that issues the above paper sheets, the paper sheets are new tickets and their serial numbers (issue numbers) are consecutive numbers. Therefore, the operator takes out the paper sheets stacked in the reject ticket stacking apparatus and inserts them between the sheets so that the serial numbers are continuous, thereby forming a handle. In order to perform such a process, it is necessary to stack the rejected tickets that have been excluded by the paper sheet processing apparatus without damaging the paper sheets.

  This type of paper sheet processing apparatus has a high transport speed for transporting paper sheets in order to process the paper sheets at high speed. When stacking paper sheets that are transported at high speed in this way, it is necessary to stack the sheets after absorbing and decelerating the kinetic energy of the transported paper sheets. For this reason, an impeller stacking device that is advantageous for high-speed stacking is often used as the stacking device for stacking the regular paper. However, this impeller accumulator is expensive due to the complexity of the mechanism and its control. Therefore, in the reject ticket stacking device of the paper sheet processing device that processes new tickets, the quality of the paper sheets is good and the number of rejected tickets is small, so a Delrin block is provided in the transport direction and transported while making contact with this block A method of accumulating by reducing energy and decelerating is known. A specific example is shown in FIG.

FIG. 7 shows an example of a conventional rejected ticket stacking apparatus 600a. In FIG. 7A, the rejected ticket sheet Pr is sandwiched and transported between the transport belt 620a wrapped around the transport roller 610a and the transport belt 620b wrapped around the transport roller 610b and transported to the reject ticket stacking device 600a. Indicates the state. In this state, since the paper sheet P has not reached the reject ticket guide 630b configured by a Delrin block having a function as a deceleration guide, the reject ticket paper Pr is not damaged. FIG. 7B shows a state in which the reject ticket sheet Pr is bent and deformed when it collides with the reject ticket guide 630b. FIG. 7C shows a state where the rejected ticket sheets Pr deformed in FIG. 7B are stacked in the rejected ticket stacking box 630a. An example of this type of rejected ticket accumulating device is shown (for example, see Patent Document 1).
JP-A-7-179264 (page 4, FIG. 1)

  However, in the rejection ticket guide composed of the conventional Delrin blocks shown in the figure, the collision surface is fixed and does not change when it collides with the rejection ticket guide, so it cannot sufficiently absorb the kinetic energy of the paper sheet. There was a problem that leaves could be damaged.

  The present invention was made in order to solve the above-mentioned problem, in order to accumulate while absorbing the kinetic energy of the paper sheet by changing the shape of the exclusion ticket guide depending on the transport state of the paper sheet being transported, It is an object of the present invention to provide an exclusion ticket stacking apparatus for a paper sheet processing apparatus that can stack without damaging paper sheets.

In order to achieve the above object, a paper sheet stacking apparatus according to claim 1 of the present invention includes an opening for taking in paper sheets conveyed at a predetermined interval, and the paper sheets taken in from the opening parts. a guide member but to guide to be transported in the transport direction downstream, and the sheet-shaped guide member disposed with a predetermined angle so as to intersect at a position opposed to the guide member in front of the guide member, With respect to the direction in which this sheet-shaped guide member is arranged toward the downstream side of the conveyance, the sheet-shaped guide member is disposed in contact with the sheet-shaped guide member in a direction orthogonal to the direction in which the sheet-shaped guide member is disposed, and the conveyed sheet paper collides with the sheet-shaped guide member. Accordingly, the paper sheet and folding amount setting guide member for setting a fulcrum and a position at which lifted the top, guided by the sheet guide member by the sheet-like guide member is the sheet And a collection box for accommodating said sheet guide member has an upper surface guide sheet and the lower surface guide two guide sheets one on top made of sheet, and the top guide sheet lower surface guide sheet portion of the distal portion of the Further, when the sheet-shaped guide member is lifted upward, the upper surface guide sheet and the lower surface guide sheet come into contact with each other by a force that presses the contact surfaces of the upper surface guide sheet and the lower surface guide sheet vertically. It is configured with a predetermined play so that the surface slides, and the frictional force of the contact surface can be varied by varying the amount of the play, so that the sheet-like guide member is lifted up It is characterized in that the restoring force at the time can be set.

  According to the present invention, since the shape of the deceleration guide changes depending on the transport state of the transported paper sheet, it is collected while absorbing the transport energy of the exclusion ticket, so that the paper sheets are stacked without damage. Therefore, it is possible to provide an exclusion ticket stacking apparatus for a paper sheet processing apparatus.

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

  FIG. 1 is a schematic cross-sectional view of a sheet processing apparatus 100 equipped with an exclusion ticket stacking apparatus 6 according to an embodiment of the present invention.

  The conveyance path 3 includes a conveyance roller disposed along the conveyance surface, a conveyance belt hung on the conveyance roller, and a driving unit that drives the conveyance roller. In this embodiment, since the paper sheet P to be transported is transported in the longitudinal direction, two transport belts having a width of about 10 m are arranged in a direction perpendicular to the transport direction. Optimum values are set for the width and number of the conveyor belts depending on the shape of the paper sheet P to be conveyed and the conveyance mode such as longitudinal conveyance or short conveyance. In addition, when processing a new ticket (new paper sheet immediately after issuance), the transported paper sheet may be soiled by the transport belt, so that belt cleaning devices 20a to 20f are provided at the folded portion of the transport belt. Is placed.

  The paper sheet inspection apparatus 4 is an apparatus that inspects the printing state of the conveyed paper sheet P. As a result of the inspection by the inspection device 4, the paper sheet P having a normal printing state is determined to be a normal sheet, and a ticket having an abnormality in the printing state as a result of the inspection is determined to be a waste paper. A ticket that cannot be inspected is identified as an excluded ticket. The rejected ticket is branched to the right side by the branch gate G1, and is collected in the rejected ticket stacking device 6 by the transport path 3a.

  When the paper sheet processing apparatus 100 processes a new ticket as in the present embodiment, the serial number (issue number) of the paper sheet P is occupied by serial sheets that are serial numbers. The bundling device 5 is composed of the correct paper stacking devices 51 and 52 and is not provided with the waste paper stacking device. However, a part of the stacking / bundling device 5 is used as a waste paper stacking device and is transported. Of course, it is possible to set so as to stack the inspection-disabled ticket such as the abnormal ticket and the two-sheet collecting ticket in the reject ticket stacking device 6.

  FIG. 2 shows the configuration of the reject ticket accumulating device 6. The paper sheet Pr determined to be a rejection ticket is transported on the transport path 3a by the branch gate G1 shown in FIG.

  The conveyance path 3a includes a conveyance roller 61a provided at the end of the conveyance path 3a, a conveyance belt 62a hung around the conveyance roller 61a, a conveyance roller 61b arranged at a position opposite to the conveyance roller 61a, and a conveyance hung around the conveyance roller 61a. It is constituted by a belt 62b, and the paper sheet Pr is nipped and conveyed by these belts. The transport speed of the transport path 3a is set to be equal to the transport speed of the paper sheet processing apparatus 100 so that the paper sheets Pr are normally stacked on the reject ticket stacking apparatus 6 even when the paper sheets Pr are continuously transported.

  The rejection ticket stacking device 6 includes a rejection ticket stacking box (stacking box) 63 having an opening 63a for taking in the paper sheet Pr held and transported by the transport belt 62a and the transport belt 62b, and a paper sheet Pr. An exclusion ticket guide sheet (sheet-like guide member) 64, a guide (folding amount setting guide member) 66, a guide (guide member) 67, and an accumulated paper for guiding the sheet so as to be aligned and accumulated on the bottom of the accumulation box 63 A detection sensor (not shown) for detecting the residual of the leaves Pr is provided.

  The exclusion ticket guide sheet 64 is fixed at a fixing point 65 at the upper part of the opening 63a, and is disposed so as to hang downward as it becomes downstream in the conveyance. The state of the sag at this time shows the amount of sag L5 in the vertical direction from the fixed point 65 to the tip of the reject ticket guide sheet 64 and the distance L6 from the opening to the tip of the reject ticket guide sheet. The details of the sag amount L5 and the distance L6 will be described later.

  The guide 66 sets a position to be a fulcrum when the reject ticket guide sheet 64 is lifted upward by the paper sheet Pr to be conveyed. By adjusting the distance from the opening 63a to the fulcrum, the strength of the waist corresponding to the spring coefficient of the reject ticket guide sheet is adjusted, and the restoring force when a paper sheet described later collides is adjusted.

  The guide 67 has a function of guiding the paper sheet Pr to the reject ticket guide sheet 64 in the reject ticket stacking box 63.

  FIG. 3 is a perspective view of the reject ticket guide sheet 64. FIG. 4 is a schematic configuration diagram of the reject ticket guide sheet 64.

  The exclusion ticket guide sheet 64 is made of a sheet material such as a Mylar sheet, and is formed by superposing an upper surface guide sheet 641 and a lower surface guide sheet 642. Moreover, the surface which both surfaces contact | abut is not closely_contact | adhered, and when a mylar sheet moves up and down, it can move so that a contact surface may shift | deviate. In the present embodiment, when the upper guide sheet 641 and the lower guide sheet 642 are overlapped, the vicinity of the front end side is combined in a nested manner. When actually used, one end is fixed to the exclusion ticket stacking box 63 at a fixed point 65 as shown in the figure.

4A is a plan view of the upper surface guide sheet 641, and FIG. 4B is a plan view of the lower surface guide sheet 642. In order to nest the upper surface guide sheet 641 and the lower surface guide sheet 642, the width W1 of the neck portion 641c of the upper surface guide sheet 641 and the width W3 of the hole 642a of the lower surface guide sheet 642 need to satisfy the following formula (1). There is.
W1 <W3 (1)

The length L1 from the fixing portion 641d of the upper surface guide sheet 641 to the maximum position of the neck portion 641c and the length L3 from the fixing portion 642b of the lower surface guide sheet 642 to the maximum position of the hole portion 642a are expressed by the following formula (2) It is necessary to satisfy.
L1 <L3 (2)

Furthermore, it is preferable that the width W2 of the upper surface guide sheet 641 and the width W4 of the lower surface guide sheet 642 satisfy the following expression (3) when the width of the paper sheet Pr is Wp.
0.5 Wp ≦ W2 (≠ W4) ≦ Wp (3)

In the embodiment, when the length Lp of the applied paper sheet P is 156 mm and the width Wp is 76 mm, the material and shape of the exclusion ticket guide sheet 64 are suitable in the following cases.
Material: Mylar sheet (4)
Exception ticket guide sheet width: W2 (≠ W4) = 46 (mm) (5)
Exclusion ticket guide sheet length: L2 (≠ L4) = 150 (mm) (6)
Exclusion ticket guide sheet thickness: T = 0.125 (mm) (7)

FIG. 5 is an assembly diagram of the exclusion ticket guide sheet 64 shown in FIG. 5A is a plan view and FIG. 5B is a side view. In this embodiment, the case where the length L2 of the upper surface mylar sheet 641 is shorter than the length L4 of the lower surface mylar sheet 642 is shown. However, as shown in the above (6), Even if there is, the effect does not change. What is important is that the length L1 is smaller than the length L3 as shown in the above equation (2), and it is necessary to ensure the assembly play ΔL when assembled. The length of ΔL varies when the paper sheet Pr is conveyed and collides with the reject ticket guide sheet 64, and the assembling play ΔL fluctuates as the reject ticket guide sheet 64 vibrates up and down by this collision force. ΔL also needs to satisfy the following equation (8) for the maximum fluctuation amount of the fluctuation.
Assembly play: ΔL ≧ 0 (8)

  FIG. 6 is a diagram for explaining the operation of the reject ticket stacking unit 6 by the reject ticket guide sheet 64 shown in FIG.

FIG. 6A shows a steady state in a state before the rejected ticket sheet Pr reaches the rejected ticket guide sheet 64. At this time, the sagging amount L5 at the tip of the reject ticket guide sheet 64 indicates the sagging amount standard value L5s. At that time, the distance from the opening 63a to the tip of the reject ticket guide sheet 64 is set to L6. Therefore, the sag angle θ at that time indicates the standard sag angle θs. In the embodiment, these values are shown in the following expressions (9) and (10).
The amount of sagging at the tip of the rejection ticket guide sheet: L5 = 50 (mm) (9)
Distance from the opening of the front end of the ticket guide sheet: L6 = 100 (mm) (10)

  The values shown in the above formulas (9) and (10) are values when the standard value of the length of the paper sheet Pr in the transport direction is assumed to be about 156 mm as described above. When the lengths of the paper sheets Pr are different values, the shape and the arrangement position of the reject ticket guide sheet 64 are different.

  FIG. 6B shows a state in which the paper sheet Pr is conveyed and reaches the rejection ticket guide sheet 64. At this time, as described above, the paper sheet Pr collides with the reject ticket guide sheet 64, and the reject ticket guide sheet 64 is lifted upward by the kinetic energy of the paper sheet Pr at the time of the collision. The amount of drooping L5 at the tip is smaller than the amount of drooping L5s. The reason why it is lifted will be described with reference to a vector diagram illustrating the reason.

  The exclusion ticket guide sheet 64 receives the force F2 when the paper sheet Pr collides. At this time, since the force F2 acting on the reject ticket guide sheet 64 is fixed at the fixing point 65, the force F3 acting in the vertical direction of the contact surface between the paper sheet Pr and the reject ticket guide sheet, and the F3 It is divided into the force F1 in the direction. The force F3 is a force that lifts the rejection ticket guide sheet 64, and the force F1 is a force that pulls the rejection ticket guide sheet 64 downstream in the transport direction. In this way, the reject ticket guide sheet 64 is lifted upward.

Next, explanation will be given regarding absorption of kinetic energy by the exclusion ticket guide sheet 64. The kinetic energy E1 possessed by the paper sheet Pr at the time of collision is expressed by the following equation 11 where m is the mass of the paper sheet Pr.
E1 = (1/2) mV ₁ ² (J) (11)

The kinetic energy E1 of the paper sheet Pr is absorbed by the rejection ticket guide sheet 64 and becomes kinetic energy E3. When the speed of the paper sheet Pr at this time is E3 its kinetic energy and V _2, represented by the following formula (12) and (13).
E3 = E1-E2 = (1/2) mV ₂ ² (J) (12)
V ₂ <V ₁ (m / s) (13)

Since the exclusion ticket guide sheet 64 is fixed at a fixed point 65, it is bent upward about the fulcrum 66a of the guide (folding amount setting guide member) 66 by the kinetic energy E2 obtained by the collision. The rejection ticket guide sheet 64 has a restoring force similar to a spring, and when the kinetic energy E1 is large immediately after the collision, the kinetic energy E2 corresponding thereto is also large, and the large collision energy is absorbed while the bending angle θ is small. As a result, the amount of sag L5 from the fixed point 65 to the tip of the reject ticket guide sheet 64 is smaller than the standard value L5s. The relationship is shown in the following formula (14).
L5 <L5s (14)

  As the paper sheet Pr further advances, the frictional force Fr increases as the contact area between the paper sheet Pr and the rejection ticket guide sheet 64 increases, and the kinetic energy E1 of the paper sheet Pr decreases due to the frictional force Fr. . Accordingly, since the kinetic energy E2 relative to it decreases, the bending angle θ of the rejection ticket guide sheet 64 increases (returns) by the restoring force of the rejection ticket guide sheet 64. As a result, the paper sheet Pr is conveyed while being decelerated while being guided by the rejection ticket guide sheet 64.

The frictional force Fr is represented by the following expression (15), where the force pressing the contact surface vertically is F3 shown in FIG.
Fr = μF3 (N) (15)
μ: Coefficient of friction between the paper sheet Pr and the rejection ticket guide sheet 64 F3: Force to press the paper sheet Pr vertically against the rejection ticket guide sheet 64

The above formula (15) shows that the frictional force Fr can be varied by the vertically pressing force F3. In the embodiment, as a method of varying the vertically pressing force F3, the size of the hole 642a of the lower surface guide sheet 642 is shown. Can be set. Even in this case, the above equation (8) needs to be established as described above.

By constructing the rejection ticket guide sheet 64 by overlapping the upper surface guide sheet 641 and the lower surface guide sheet 642, the restoring force (spring force) obtained when the rejection ticket guide sheet 64 is bent is doubled. In the embodiment, it is preferable. By making two sheets in this way, the above-described frictional force Fr and restoring force can be set optimally.

  That is, by this series of operations, the kinetic energy E1 of the paper sheet Pr is continuously reduced and accumulated at a predetermined position along with the restoring force of the rejection ticket guide sheet 64.

  FIG. 6C is a diagram illustrating a state in which the paper sheets Pr are stacked through FIGS. 6A and 6B. Even when the paper is continuously conveyed by the above-described method, the paper sheets Pr can be stacked without damaging the leading edge of the paper sheets Pr.

  As described above, according to the present embodiment, the shape of the reject ticket guide sheet changes depending on the transport state of the transported paper sheet, and the kinetic energy of the reject ticket is collected while being collected. Accumulate without damaging.
