LEAF PAPER BUNDLING APPARATUS
BACKGROUND OF THE INVENTION
The present invention relates to a leaf paper bundling apparatus that winds tape around the outside of leaf paper that is held in a bundling position, cuts the tape and uses thermal bonding to bundle the leaf paper.
Conventional leaf paper bundling apparatus, as disclosed in Japanese Patent Laid-Open Publication No.
109723/1987, stacks the leaf paper that is to be bundled, at a stacking portion, conveys the stacked leaf paper to a bundling portion by conveyor means when the number of leaves has reached a certain number (in the case of banknotes, this number is customarily 100 of the same denomination), holds the stack between holder at the bundling portion, introduces a divider between the leaf paper held in the holder so that removing the divider winds the tape around the leaves and the holder when the ends of tape are held between the leaves, and bonding the cut end portions of the tape after they have been cut to complete the bundling operation. The bundled leaf paper is then pushed out from the-space between the holders.
In addition, a different type of lea~ paper bundling apparatus only performs bundling and in this type for example, an operator creates a stack of 100 notes of the same denomination and introduces them by hand into a bundling portion of a leaf paper bundling apparatus so that a portion other than the portion that is being held by hand is supported by a holder and a divider is inserted in between the leaves of this portion of the stack and tape ends are placed inside the stack so that removing the divider holds the tape ends between the leaves, and winds the tape around the holder as well, the tape is cut and the cut end portions of the tape are bonded to complete the bundling operation. An operator then manually removes the bundled leaf paper from the space between the holders.
~owever, in the former of these two types of 2 ~
conventional apparatus, the tape is wound around both the holder and the leaf paper that it holds and so it is necessary to use a pusher to push the end portion of the bundle in order to expel it from the holder, and there is a first problem that the end portion that is pressed may be marked by the pusher. In addition to this, there is the additional problem with both the former and the latter apparatus that when it is easy for the neat bundle to become uneven when the bundle is removed from the holder, and this greatly deteriorates the appearance of the bundled paper.
A third problem exists in that, when the leaf paper is bundled by the tape, the leading edge of the tape iIl the direction in which it is wound is turns down the leaves when the tape is wound and this further deteriorates the appearance of the bundle.
A first objec~ive of the present invention is to solve the first and second problems by the provision of a leaf paper bundling apparatus that bundles leaf paper by winding ~0 tape directly around the leaf paper, and that does not slacken the tape when there is bundling.
A second objective of the present invention is to solve the first, second and third problems by winding tape directly around the leaf paper, and by not allowing the leaf paper be turned down even when the tape is wound during bundli.ng.
SUMMARY OF THE INVENTION
The present invention that solves the first and second of the problems described above for the conventional technology is a leaf paper bundling apparatus that winds tape around a periphery of a stack of leaf paper at a portion other than that which is held by the bundling apparatus, and performs cutting and thermal bonding of the tape ends to bundle the leaf paper, and which further comprises by a tape winding means that winds tape around a periphery of a stack of leaf paper at a portion other than 2~ 3 that which is held by the bundling apparatus, clamping means that, after the tape is wound, tightens in the vicinity of a tape winding portion of the leaf paper, and tape tightening means to apply tension to the tape, in which said clamp means has a first and a second clamping member that contact the top and bottom leaves of the the leaves that are to be bundled, and clamp, and in which each of these clamping members has a pair of contact edges that are positioned on either side across the width of the banknotes at the portion where the tape is wound, so that when the leaf paper is clamped by the first and second clamping members, a tape thermal bonding pad is inserted in between the contact edges of one of the clamping members.
The second embodiment of the present invention that solves the first, second and third problems described above for the conventional technology is a leaf paper bundling apparatus in which left and right contact edges of first and second clamping members contact the top and bottom leaves of a stack of leaf paper, at a portion other than that which is held by the bundling apparatus, the stack of leaf paper is compressed and held between these contact edges of the first and second clamping members and a tension is applied to the tape as soon as it has been wound, and when the tape is cut or immediately prior to or after the tape has been cut, a thermal bonding pad is inserted between the contact edges of one of the clamping members to thermally bond the tape so that releasing the clamping of the stack of leaf paper allows the prompt removal of the bundled paper.
In addition, in the first and second embodiments, in addition to the action described above, the length of the pair of contact edges provided to each of the first and second clamping members,is such that it is longer than the width of the banknotes in the direction of winding around the leaf paper stack and so the entire width of the portion around which the tape is wound is compressed so that the tape which has been wound around the stack of leaf paper CA 020264~6 1997-08-13 and to which a tension has been applied, does not bend the edges of the leaf paper towards the inside, and a neat bundle is performed.

DE~CRIPTION O~ THE PREFERR~D EMBODIMENTS
The following is a detailed description of an embodiment according to the present invention, with reference to the appended drawings.
In this embodiment, the description will be given for the case where the leaf paper to be bundled is banknotes, with FIG. 1 being an external view of a banknote identification, counting and bundling apparatus (hereinafter called as ~the banknote bundling apparatus") into which the bundling device according to the present invention has been applied, and FIG. 2 being a diagrammatic view of the internal layout thereof. In FIG. 2, the left side is the front of the banknote bundling apparatus 1 and a bundling device 2 is incorporated into a machine frame 3, with this machine frame 3 being so that it can be pulled out from the front of the banknote bundling apparatus 1.
The front portion and the top portion at the front of the banknote bundling apparatus 1 has doors 4,5 that can be fr ely opened to allow maintenance and inspection of the inside of the bundling device 2.
To the front at the top of the banknote bundling apparatus 1 is a hopper 6 into which are loaded the banknotes P that are to be bundled, and a reject portion 7 for the return to a position immediately above, of banknotes that are not suitable for bundling (because they are of different denominations, counterfeit, or damaged).
As is shown in FIG. 1, inside the banknote bundling apparatus 1 is a conveyor path 9 that has an identification portion 8 that uses transfer means (not indicated in the figure) to identify each of the banknotes P that have been 2~2~
placed in the hopper 6, and separation flngers 10 on a separation portion of this conveyor path 9 so that banknotes that can be bundled are sent to a stacking portion 11 and banknotes that cannot be bundled are sent to the reject portion 7.
As shown in FIG. 3, the bundling device 2 is provided with the stacking portion 11 that aligns both the long and short edges of the banknotes that are sent via the conveyor path 9 and which collates and stacks a predetermined number of banknotes, holding and transfer means 12 that holds and transfers the collated and stacked banknotes in that state from the stacking portion 11 to a bundling position A
immediately beneath, clamping means 13 that clamps and holds the banknotes from both sides at a position that is ~5 separate from the position where the banknotes are held for transfer to the bundling position A, a supply means 14 that supplies a tape T for bundling, tape winding means 15 that winds the tape around the banknotes, a cutter mechanism 16 that cuts the tape T after it has been wound and tension applied thereto, and an thermal bonding pad 17 that heats and adheres the cut ends of the tape T.
The stacking portion 11 has a receiving portion 18 which is roughly L,-shaped in elevation, and an upper portion of an upright portion 19 of the receiving portion 18 is mounted to a shaft 21 at one end of a rocker lever 20. A cam follower 22 at the other end of this rocker lever 20 contacts a cam 23 and the rotation of the cam 23 is transferred to rock the rocker lever 20. An outside end edge of a bottom portion 24 of the receiving portion 18 is formed with a plural number of cutouts 25,25,,, (indicated in FIG. 6) and peripheral portions of vane wheels 26,26,,, provided at the end oE the conveyor path 9 enter into these cutouts 25,25,,, so that the banknotes that P are sent from the end of the conveyor path 9 are received one at a time by these vane wheels 26,26,,, so that the rotation of the vane wheels 26,26,,, in the direction indicated by the arrow in FIG. 3 and FIG. 6 causes the banknotes P to remain ~2~4.~
on the bottom portion ~24. Also, the bottom portion 24 is provided with a presser plate 27 that gradually advances and retreats in accordance with the quantity of stacked banknotes P that are sent to the bottom portion 24 by the vane wheels 26,26,,, and the presser plate 27 is supported by a link mechanism (not indicated in the figure), so that spring action always urges the stacked banknotes P at a constant force and in the direction of the vane wheels 26,26,,,. Moreover, the vane wheels 26,26,,, used here are known and has a plural number of vanes 30,30,,, curved in the same direction and embedded in the outer surface of a boss portion 29 fixed to a shaft 28, so that banknotes are received one at a time between the vanes and are carried to the side of the stacking portion 11. In addition, 18A is a guide plate for when the banknotes P are moved to the bundling position A, has a comb shape and prevents the entry of the holding fingers into the holding and transfer means 12 to be described later.
To one end of the stacking portion 11 is provided a fixed wall 31 that is the reference for aligning the long edges of the banknotes that are collated and stacked on the bottom portion 24 of the receiving portion 18, and to the side at the other end is provided a long side alignment mechanism 32 that presses the edges of the stacked banknotes P in the direction of the fixed wall 31 and aligns them.
As indicated in perspective view in FIG. 5, this long side alignment mechanism 32 has a belt 39 wound around a pulley 35 on a shaft (not shown) of a forward/reverse drive motor 34 fixed to the machine base 33, a pulley 36 axially supported on the machine base 33, and intermediate pulleys 37,38 so that a forward/reverse rotation is applied within a predetermined angular range to the pulley 36. And arm 40 is horizontally fixed to the pulley 36 and to a distal end of the arm 40 is provided an upright, round aligning rod 42 via a bracket 41. Accordingly, the arm 40 swivels from the position indicated by the solid line in FIG. 5, to the ~32~r~
position indicated by the dotted line so that the round aligning rod 42 comes into contact with one end portion in the direction of the long side of the banknotes P on the receiving portion 18 and presses the banknotes P towards the side of the fixed wall 31, and the banknotes P are aligned using the fixed wall 31 as a reference. Moreover, the angle of rotation of the drive motor 34 is selected so that changing the swivel angle of the round aligning rod 42 enables it to correspond to banknotes P of different lengths. In addition, the alignment operation by the round aligning rod 42 is intermittently driven so that there is one operation for each 10-20 banknotes P that are sent to the receiving portion 18.
As shown in FIG. 6, both sides of the stacking portion 11 are provided with short-direction alignment mechanisms 43,43 that align the upper ends of the banknotes P that are stacked and aligned in the receiving portion 18. These short-direction alignment mechanisms 43,43 are provided symmetrically left and right as indicated in the plan view of FIG. 7 and in the perspective view of FIG. 6, but for the sake of convenience, the description will be only for one side (the left side), with corresponding numerals used for corresponding portions on the other side.
The configuration of the short-direction alignment mechanism 43 comprises a solenoid 44 fixed to an outer surface of the machine frame 3, an alignment member 46 for which a base end is supported by a shaft 45 and which freely swivels in the direction of the stacking portion 11, a lever 47 having a ~<" shape and to which one end is linked to the rear side near the base end of the alignment member 46, and a lever 48, one end of which is supported by the machine frame 3 and the other end is linked to the other end of the lever 47. The plunger 44a of the solenoid 44 is linked to a pin 50 of a pivot 49 of the lever 48 so that when the plunger 44a is contracted, then as indicated by the dotted line in FIG. 7, the alignment member 46 swivels from the top portion on the side of the receiving 2 ~
portion 18 to the lower portion, and the alignment portion 46a that is the distal end of the alignment member 46 bent at right angles, taps the upper ends of the banknotes P
that are collated and stacked on the stacking portion 11.
These short-direction alignment mechanisms 43,43 are intermittently driven in the same manner.
The holding and transfer means 12 has left and right holding fingers 52,53 positioned on either side of the bundling position A, and are located at positions a certain distance between the the short ends and the centers of the banknotes P. As indicated in the plan view of FIG. 8, and the elevational view in FIG. 9, the holding fingers 52,53 each have these ends of two parallel arms 54,55 and 56,57 respectively pivoted to their base portions and the other ends of the parallel arms 54,55 and 56,57 are either directly or indirectly pivoted on the side of the banknote bundling apparatus 1 so that they configure a parallel link mechanism in which each of the holding fingers 52,53 can maintain a mutually parallel status while advancing and retreating. In FIG. 8, a cam follower 58 is pivotally mounted to the base end curved portion of one of the arms 54 of one of the holding fingers 52 on one side (the left side) and a spring (not indicated in the figure) brings it into contact with the surface of a cam 59 pivotally supported on the machine frame 3, the base end of one of the arms 56 of the holding finger 52 of the other side (the right side) is linked to an auxiliary lever 61 supported by a pivot 60 to the machine frame 3, and a cam follower 62 pivotally mounted to the base curved portion of the auxiliary lever 61 is urged by a spring 64 to contact the surface of a cam 63 on the same shaft as the cam 59.
Accordingly, because of the action of the spring 64 when the holding finger 52 comes into contact with the banknotes P, it is possible to correspond to banknotes P of different thicknesses.
One oE the holding surfaces of the holding fingers 52,53 has, as shown in FIG. 9, a protrusion surface 52a on 2~26 which there are circular protrusions, and the other of the holding surfaces of the holding fingers 52,53 has a recess surface 53a on which there are circular recesses corresponding to the circular protrusions in the protrusion 5 surface 52a, so that when banknotes P are held between the holding fingers 52,53, they bent along its long direction and do not slip even when they are held from one side only.
A lift mechanism 66 of a machine base 65 that supports these holding fingers 52,53 has, as indicated in FIG. 9, is supported by a shaft 67 having a non-circular cross section and which has its upper and lower ends supported by the machine base 65 so that it cannot rotate, and a pulley 71 is rotated by a motor 68 on the machine frame 3 via a worm gear 69 and a worm wheel 70, and a belt 73 is wound around the pulley 71 and a pulley 72 pivotally supported towards the bottom of the machine frame 3, with the belt 73 and the machine base 65 being linked by a linking member 74 so that the rotational movement of the belt 73 raises and lowers the machine base 65.
A belt 77 is wound around a pulley 75 that rotates by the rotation of the motor 68, and a pulley 76 on the shaft 67 and a belt 81 is wound around another pulley 78 on the shaft 67 and a pulley 80 on a shaft 79 of the cams 59 and 63 mentioned above, so that it applies a rotational motion to these cams so that the cam shape of these cams 59,63 moves the holding fingers 52,53 in the direction whereby the come together, and in the direction where they return to the position indicated in FIG. 8.
In addition, as shown in FIG. 8, towards the bottom of the shaft 67 are provided a detector plate 67a and a detection sensor S6 in order to detect the rotational position of the shaft 67, and these detect the holding position and the opening position of the holding fingers 52,53.
The machine frame 3 is provided with sensors S1, S2 and S3 that detect the position of the machine base 65. Sensor S1 detects the standby position (the position indicated in 2 ~
FIG. 3), the sensor S2 detects the position where the stacking portion 11 holds the banknotes P and the sensor S3 detects the position where the movement to the bundling position A stops.
As indicated in FIG. 3 and FIG. 4, the clamping means 13 has left and right clamping members 82,83 shaped like a letter C, when seen from above, and opposing each other, and the left and right clamping members 82,83 are disposed on the left and right sides of the bundling position A, so that position where the banknotes P are held by the holding fingers 52,53 is maintained at a position close to the opposite end.
One of the clamping members 82 (the left clamping member in the diagram) is supported so that it guides guide shafts 84,85 provided on the machine frame 3 and freely advances towards and retreats from the bundling position A, and the base end at the bottom of the machine frame 3 is linked with play by a long hole 88 and a pin 87 to the top end of a lever 86 that is pivotably supported, and a cam follower 89 pivotably attached along the lever 86 receives an urging force of a spring and contacts the surface of a cam 90, so that the rotational motion of this cam causes the clamping member 82 to freely advance and retreat along the guide shafts 84,85.
In this embodiment, a stamp 91 is built into the clamping member 82 and the stamp 91 freely advances and retreats along the guide shafts 92,93, and the upper end of a lever 94 pivotable supported on the same shaft as the lever 86 is freely linked by a pin and a long hole. A cam follower 95 pivotably attached along the lever 94 receives the urging force of a spring and is brought into contact with the surface of another cam 96 on the same shaft. The shape of the cam 96 causes the stamp 91 to advance for a predetermined time as will be described later, and to perform a stamping operation.
The clamping member 83 on the other side (the right side in the diagram) is escapably supported by springs 2~2~
99,100 so that it freely advances and retreats along the guide shafts 97,98 provided to the machine frame 3, in the direction of the bundling position A , and a base portion towards the bottom of the machine frame 3 is linked with play by a pin 102 and a long hole 103, so that a cam follower 104 pivotable attached along this lever 101 receives an urging force of a spring and is brought into contact with the surface of a cam 105. The shape of the cam 105 is such that the clamping member 83 advances to slightly ahead of the clamping member 82 previously described.
To an upper portion of the C-shaped inner portion of the clamping member 83 are fixed tape guides 107 that have a C-shape when seen in plan, and on which guides 106,106 at the left and rlght dlstal ends open outwards as indicated in FIG. 10, and the width of the inside portion is slightly wider than the width of the tape T. In addition, the banknote P contact edges 83a,83a of the clamping member 83 have a width that extends in the longitudinal direction as indicated in FIG. 11 and have portions a,a opposing contact edges 82a,82a of the clamping member 82, and which have positions b,b opposing both side portions of 108 which is to be described later. Accordingly, the portions a,b can be formed by being the end of the clamping member 83 at right angles. However, as indicated in FIG. 12, a separate member 109 can be fixed to the inner side of the clamping member 82 and the opposing portions b,b formed as the contact edges 83a,83a.
As indicated in FIG. 3 and FIG. 4, the tape supply means 14 has a flat tape passage 111 to guide the tape T
led via intermediate reels 110,110,,, from a tape reel (not indicated in the figure), and a leading end of the passage 111 is open in the direction of the bundling position A, and of the upper and lower rollers 112,113 that are tape supply rotating bodies at the trailing end of this passage 111, the roller 113 (or a belt) is rotatably driven by a pulse motor 114 so that it can be driven in the forward and 2 ~
reverse directions, and so the tape T is fed out by the necessary amount and so that if necessary, the motor can be reversed to apply a tension to the tape T. In the vicinity of the leading end of the tape passage 111 is provided a sensor S4 to detect the leading end position of the tape T.
As indicated in FIG. 13, the tape winding means 15 has a movable holding member 116 and a fixed holding member 115 that holds the fed out end of the tape T, and the holding members 115,116 advance and retreat and swivel so as to describe an arc path indicated by the letter B in FIG. 3, at the bundling position A.
The fixed holding member 115 is provided fixed to the distal end of a swivel arm 119 supported so as to be freely rotatable by a shaft 118 to a moving frame 117, and the movable holding member 116 has a structure that opens and closes with respect to the fixed holding member 115 supported by a shaft 120 to the previously mentioned swivel arm 119, and a spring 121 fitted between its base end and a swivel arm 119 urges the distal ends of both holding members 115,116 to close. In addition, the curved end of the base portion of the movable holding member 116 has a cam follower 122 pivotably attached to it and the cam follower 122 is provided so as to be in free contact with a cam portion 124 of a cam member 123 provided to the side of ~5 the machine frame 3, so that when the cam follower 122 rides onto the cam member 124 (the status indicated in FIG.
13), the distal end of the movable holding member 116 is separated from the distal end of the fixed holding member 115.
The cam member 123 is rotatably supported inside its horizontal surface by a shaft 125 on the side of the machine frame 3, and the cam member 123 is linked via a linkage lever 128 with a plunger 127 of a solenoid 126, so that when the plunger 127 is contracted, the cam member 124 is guided by a roller 130 on the side of the machine frame 3 and which engages with a curved long hole 129, and is swivelled in the anticlockwise direction (the direction of 2 ~
the arrow, in FIG. 13) around the center of the shaft 125.
The moving frame 117 that supports the holdi.ng members 115,116 is supported so as to freely advance and retreat along guide shafts 131,131 fixed to the machine frame 3, and a gear 132 is pivotably attached to the moving frame 117, with the direction of motion of the moving frame 117 being the direction of the shaft.
The mechanism that retreats the moving frame 117 has one end of a lever 136 pivotably and eccentrically attached with respect to a shaft 134 of a member 135 fixed to the shaft 134 of a motor 133 mounted to the machine frame 3, and the other end of the lever 136 is linked to the moving frame 117 by one end of a -;ocker arm 138 pivoted by a shaft 137, and a long hole 139 on the other side of the rocker arm 138 engages with a pin 140 of the moving frame 117, so that the motor 133 advances and retreats the moving frame 117 by a predetermined stroke, via the lever 136 and the rocker arm 138.
The gear 132 engages with a long gear 141 having elongated teeth and which is pivotably supported on the side of the machine frame 3 and is status of engagement of the gears 132,141 is maintained even when the moving frame 117 is advanced or retreated. In addition, the gear 141 on the side of the machine frame 3 transmits the rotation of a motor 142 via a timing belt 143. Moreover, Ss is a rotation detection sensor and 144 is a detection plate having a detection portion 145.
As shown in FIG. 14 and FIG. 15, the cutter mechanism 16 cuts the tape T by swiveling when a solenoid 148 moves a cutter arm 147 having a blade perpendicularly attached at its distal end, downwards and the lever mechanism is provided between a plunger 149 and the cutter arm 147 so as to increase the swivel angle of a blade 146 with respect to the stroke of the plunger 149 of the solenoid 148. This lever mechanism links one end of a short lever 152 to one end of an L-shaped lever 151 pivoted at its bend by a shaft 150 on the machine frame 3, and the other end of the lever ~2~j6 152 is linked at a position close to a pivot shaft 153 of the cutter arm 147, so that when the plunger 149 is contracted, the L-shaped lever 151 rotates about the center of the pivot 150 in the clockwise direction indicated in the figure, the short lever 152 is raised, and the cutter arm 147 rotates about the center of the pivot 153 and swivels a large distance in the clockwise direction indicated in the figure.
As shown in FIG. 3, the thermal bonding pad mechanism 17 has a lever 156 pivotably attached to the lower end of an arm 155 to which one end is pivoted by a shaft 154 to the machine frame 3, and is at a constant position with respect to the arm 155 that is drawn by a spring 157, and the lever 156 has a thermal bonding pad mounted to it. Cam followers 159,160 pivotably mounted along the arm 155 receive the urging force of the spring 157 and are successively brought into contact with the cam surface, and the rotation of a cam 161 swivels so that a thermal bonding pad 158 swivels in the direction of the bundling position A, and in the diagram, the clamping means 13 enters from the bottom into the clamping member 82 on the left side.
A separate pressing-down lever 162 is mounted to the shaft 154 of the arm 155 as the means to press the tape T, and a receiving portion 163 at its distal end contacts the lower end of the tape T that is wound around the banknotes P at the bundling position A, and is structured so that the tape T does not slacken.
The following is an explanation of the operation of the embodiment described above.
In FIG. 1 and FIG. 2, the banknotes P that are to be bundled are placed on the hoper 6 of the bundling machine 1, so that pressing the start button takes the banknotes one at a time into the inlet means (not indicated in the diagram). The banknotes P that have been taken in are identified by the identification means 8 as to whether or not they are banknotes P suitable for bundling, and if they are suitable, are sent to the stacking portion 11 via the 2~
conveyor path 9, and if they are banknotes P of differing denominations, counterfeit banknotes or doubly fed banknotes that are not suitable for bundling, then the a signal ~rom the identification portion 8 switches the separation fingers 10 and the unsuitable banknotes P are returned to the reject portion 7. The banknotes P that are sent to the stacking portion 11 are sent to the receiving portion 18 after having been taken in one at a time between the vanes 30,30,,, of the vane wheels 26,26,,, and are left on the bottom portion 24 where they are successively collated and aligned in an upright position.
During this time, the round aligning rod 42 is intermittently driven by the long side alignment mechanism 32 so that it swivels and strikes one of the long ends of the banknotes P while the other of the long ends of the banknotes P is pressed against the fixed wall 31 so that the edges of the banknotes P are aligned. In addition, at the same time, the short-direction alignment mechanisms 43,43 intermittently operate and their alignment members 46,46 swivel and press the upper edge of the banknotes P
with the alignment portion 46a so that the edges of the banknotes P are aligned in the short direction.
As indicated in FIG. 16A through FIG. 16K, when a predetermined number of banknotes P (customarily 100) are stacked in the aligned status in the stacking portion 11, the driving of the motor 68 of the holding and transfer means 12 causes the machine base 65 to rise because of the belt 73 and the left and right holding fingers 52,53 rise in the open status and proceed to positions between the center and the short ends of the banknotes P in the stacking portion 11, where they holding fingers 52,53 close by the rotation of the cams 59,60 that are rotated by the motor 68, and hold the banknotes P between them (See FIG.
16A).
After the banknotes P have been held, the rotation of the cam 23 rocks the rocker lever 20 around the pivot 21 and in the clockwise direction as indicated in the FIG.
LEAF PAPER BUNDLING APPARATUS
BACKGROUND OF THE INVENTION
The present invention relates to a leaf paper bundling apparatus that winds tape around the outside of leaf paper that is held in a bundling position, cuts the tape and uses thermal bonding to bundle the leaf paper.
Conventional leaf paper bundling apparatus, as disclosed in Japanese Patent Laid-Open Publication No.
109723/1987, stacks the leaf paper that is to be bundled, at a stacking portion, conveys the stacked leaf paper to a bundling portion by conveyor means when the number of leaves has reached a certain number (in the case of banknotes, this number is customarily 100 of the same denomination), holds the stack between holder at the bundling portion, introduces a divider between the leaf paper held in the holder so that removing the divider winds the tape around the leaves and the holder when the ends of tape are held between the leaves, and bonding the cut end portions of the tape after they have been cut to complete the bundling operation. The bundled leaf paper is then pushed out from the-space between the holders.
In addition, a different type of lea~ paper bundling apparatus only performs bundling and in this type for example, an operator creates a stack of 100 notes of the same denomination and introduces them by hand into a bundling portion of a leaf paper bundling apparatus so that a portion other than the portion that is being held by hand is supported by a holder and a divider is inserted in between the leaves of this portion of the stack and tape ends are placed inside the stack so that removing the divider holds the tape ends between the leaves, and winds the tape around the holder as well, the tape is cut and the cut end portions of the tape are bonded to complete the bundling operation. An operator then manually removes the bundled leaf paper from the space between the holders.
~owever, in the former of these two types of 2 ~
conventional apparatus, the tape is wound around both the holder and the leaf paper that it holds and so it is necessary to use a pusher to push the end portion of the bundle in order to expel it from the holder, and there is a first problem that the end portion that is pressed may be marked by the pusher. In addition to this, there is the additional problem with both the former and the latter apparatus that when it is easy for the neat bundle to become uneven when the bundle is removed from the holder, and this greatly deteriorates the appearance of the bundled paper.
A third problem exists in that, when the leaf paper is bundled by the tape, the leading edge of the tape iIl the direction in which it is wound is turns down the leaves when the tape is wound and this further deteriorates the appearance of the bundle.
A first objec~ive of the present invention is to solve the first and second problems by the provision of a leaf paper bundling apparatus that bundles leaf paper by winding ~0 tape directly around the leaf paper, and that does not slacken the tape when there is bundling.
A second objective of the present invention is to solve the first, second and third problems by winding tape directly around the leaf paper, and by not allowing the leaf paper be turned down even when the tape is wound during bundli.ng.
SUMMARY OF THE INVENTION
The present invention that solves the first and second of the problems described above for the conventional technology is a leaf paper bundling apparatus that winds tape around a periphery of a stack of leaf paper at a portion other than that which is held by the bundling apparatus, and performs cutting and thermal bonding of the tape ends to bundle the leaf paper, and which further comprises by a tape winding means that winds tape around a periphery of a stack of leaf paper at a portion other than 2~ 3 that which is held by the bundling apparatus, clamping means that, after the tape is wound, tightens in the vicinity of a tape winding portion of the leaf paper, and tape tightening means to apply tension to the tape, in which said clamp means has a first and a second clamping member that contact the top and bottom leaves of the the leaves that are to be bundled, and clamp, and in which each of these clamping members has a pair of contact edges that are positioned on either side across the width of the banknotes at the portion where the tape is wound, so that when the leaf paper is clamped by the first and second clamping members, a tape thermal bonding pad is inserted in between the contact edges of one of the clamping members.
The second embodiment of the present invention that solves the first, second and third problems described above for the conventional technology is a leaf paper bundling apparatus in which left and right contact edges of first and second clamping members contact the top and bottom leaves of a stack of leaf paper, at a portion other than that which is held by the bundling apparatus, the stack of leaf paper is compressed and held between these contact edges of the first and second clamping members and a tension is applied to the tape as soon as it has been wound, and when the tape is cut or immediately prior to or after the tape has been cut, a thermal bonding pad is inserted between the contact edges of one of the clamping members to thermally bond the tape so that releasing the clamping of the stack of leaf paper allows the prompt removal of the bundled paper.
In addition, in the first and second embodiments, in addition to the action described above, the length of the pair of contact edges provided to each of the first and second clamping members,is such that it is longer than the width of the banknotes in the direction of winding around the leaf paper stack and so the entire width of the portion around which the tape is wound is compressed so that the tape which has been wound around the stack of leaf paper CA 020264~6 1997-08-13 and to which a tension has been applied, does not bend the edges of the leaf paper towards the inside, and a neat bundle is performed.

DE~CRIPTION O~ THE PREFERR~D EMBODIMENTS
The following is a detailed description of an embodiment according to the present invention, with reference to the appended drawings.
In this embodiment, the description will be given for the case where the leaf paper to be bundled is banknotes, with FIG. 1 being an external view of a banknote identification, counting and bundling apparatus (hereinafter called as ~the banknote bundling apparatus") into which the bundling device according to the present invention has been applied, and FIG. 2 being a diagrammatic view of the internal layout thereof. In FIG. 2, the left side is the front of the banknote bundling apparatus 1 and a bundling device 2 is incorporated into a machine frame 3, with this machine frame 3 being so that it can be pulled out from the front of the banknote bundling apparatus 1.
The front portion and the top portion at the front of the banknote bundling apparatus 1 has doors 4,5 that can be fr ely opened to allow maintenance and inspection of the inside of the bundling device 2.
To the front at the top of the banknote bundling apparatus 1 is a hopper 6 into which are loaded the banknotes P that are to be bundled, and a reject portion 7 for the return to a position immediately above, of banknotes that are not suitable for bundling (because they are of different denominations, counterfeit, or damaged).
As is shown in FIG. 1, inside the banknote bundling apparatus 1 is a conveyor path 9 that has an identification portion 8 that uses transfer means (not indicated in the figure) to identify each of the banknotes P that have been 2~2~
placed in the hopper 6, and separation flngers 10 on a separation portion of this conveyor path 9 so that banknotes that can be bundled are sent to a stacking portion 11 and banknotes that cannot be bundled are sent to the reject portion 7.
As shown in FIG. 3, the bundling device 2 is provided with the stacking portion 11 that aligns both the long and short edges of the banknotes that are sent via the conveyor path 9 and which collates and stacks a predetermined number of banknotes, holding and transfer means 12 that holds and transfers the collated and stacked banknotes in that state from the stacking portion 11 to a bundling position A
immediately beneath, clamping means 13 that clamps and holds the banknotes from both sides at a position that is ~5 separate from the position where the banknotes are held for transfer to the bundling position A, a supply means 14 that supplies a tape T for bundling, tape winding means 15 that winds the tape around the banknotes, a cutter mechanism 16 that cuts the tape T after it has been wound and tension applied thereto, and an thermal bonding pad 17 that heats and adheres the cut ends of the tape T.
The stacking portion 11 has a receiving portion 18 which is roughly L,-shaped in elevation, and an upper portion of an upright portion 19 of the receiving portion 18 is mounted to a shaft 21 at one end of a rocker lever 20. A cam follower 22 at the other end of this rocker lever 20 contacts a cam 23 and the rotation of the cam 23 is transferred to rock the rocker lever 20. An outside end edge of a bottom portion 24 of the receiving portion 18 is formed with a plural number of cutouts 25,25,,, (indicated in FIG. 6) and peripheral portions of vane wheels 26,26,,, provided at the end oE the conveyor path 9 enter into these cutouts 25,25,,, so that the banknotes that P are sent from the end of the conveyor path 9 are received one at a time by these vane wheels 26,26,,, so that the rotation of the vane wheels 26,26,,, in the direction indicated by the arrow in FIG. 3 and FIG. 6 causes the banknotes P to remain ~2~4.~
on the bottom portion ~24. Also, the bottom portion 24 is provided with a presser plate 27 that gradually advances and retreats in accordance with the quantity of stacked banknotes P that are sent to the bottom portion 24 by the vane wheels 26,26,,, and the presser plate 27 is supported by a link mechanism (not indicated in the figure), so that spring action always urges the stacked banknotes P at a constant force and in the direction of the vane wheels 26,26,,,. Moreover, the vane wheels 26,26,,, used here are known and has a plural number of vanes 30,30,,, curved in the same direction and embedded in the outer surface of a boss portion 29 fixed to a shaft 28, so that banknotes are received one at a time between the vanes and are carried to the side of the stacking portion 11. In addition, 18A is a guide plate for when the banknotes P are moved to the bundling position A, has a comb shape and prevents the entry of the holding fingers into the holding and transfer means 12 to be described later.
To one end of the stacking portion 11 is provided a fixed wall 31 that is the reference for aligning the long edges of the banknotes that are collated and stacked on the bottom portion 24 of the receiving portion 18, and to the side at the other end is provided a long side alignment mechanism 32 that presses the edges of the stacked banknotes P in the direction of the fixed wall 31 and aligns them.
As indicated in perspective view in FIG. 5, this long side alignment mechanism 32 has a belt 39 wound around a pulley 35 on a shaft (not shown) of a forward/reverse drive motor 34 fixed to the machine base 33, a pulley 36 axially supported on the machine base 33, and intermediate pulleys 37,38 so that a forward/reverse rotation is applied within a predetermined angular range to the pulley 36. And arm 40 is horizontally fixed to the pulley 36 and to a distal end of the arm 40 is provided an upright, round aligning rod 42 via a bracket 41. Accordingly, the arm 40 swivels from the position indicated by the solid line in FIG. 5, to the ~32~r~
position indicated by the dotted line so that the round aligning rod 42 comes into contact with one end portion in the direction of the long side of the banknotes P on the receiving portion 18 and presses the banknotes P towards the side of the fixed wall 31, and the banknotes P are aligned using the fixed wall 31 as a reference. Moreover, the angle of rotation of the drive motor 34 is selected so that changing the swivel angle of the round aligning rod 42 enables it to correspond to banknotes P of different lengths. In addition, the alignment operation by the round aligning rod 42 is intermittently driven so that there is one operation for each 10-20 banknotes P that are sent to the receiving portion 18.
As shown in FIG. 6, both sides of the stacking portion 11 are provided with short-direction alignment mechanisms 43,43 that align the upper ends of the banknotes P that are stacked and aligned in the receiving portion 18. These short-direction alignment mechanisms 43,43 are provided symmetrically left and right as indicated in the plan view of FIG. 7 and in the perspective view of FIG. 6, but for the sake of convenience, the description will be only for one side (the left side), with corresponding numerals used for corresponding portions on the other side.
The configuration of the short-direction alignment mechanism 43 comprises a solenoid 44 fixed to an outer surface of the machine frame 3, an alignment member 46 for which a base end is supported by a shaft 45 and which freely swivels in the direction of the stacking portion 11, a lever 47 having a ~<" shape and to which one end is linked to the rear side near the base end of the alignment member 46, and a lever 48, one end of which is supported by the machine frame 3 and the other end is linked to the other end of the lever 47. The plunger 44a of the solenoid 44 is linked to a pin 50 of a pivot 49 of the lever 48 so that when the plunger 44a is contracted, then as indicated by the dotted line in FIG. 7, the alignment member 46 swivels from the top portion on the side of the receiving 2 ~
portion 18 to the lower portion, and the alignment portion 46a that is the distal end of the alignment member 46 bent at right angles, taps the upper ends of the banknotes P
that are collated and stacked on the stacking portion 11.
These short-direction alignment mechanisms 43,43 are intermittently driven in the same manner.
The holding and transfer means 12 has left and right holding fingers 52,53 positioned on either side of the bundling position A, and are located at positions a certain distance between the the short ends and the centers of the banknotes P. As indicated in the plan view of FIG. 8, and the elevational view in FIG. 9, the holding fingers 52,53 each have these ends of two parallel arms 54,55 and 56,57 respectively pivoted to their base portions and the other ends of the parallel arms 54,55 and 56,57 are either directly or indirectly pivoted on the side of the banknote bundling apparatus 1 so that they configure a parallel link mechanism in which each of the holding fingers 52,53 can maintain a mutually parallel status while advancing and retreating. In FIG. 8, a cam follower 58 is pivotally mounted to the base end curved portion of one of the arms 54 of one of the holding fingers 52 on one side (the left side) and a spring (not indicated in the figure) brings it into contact with the surface of a cam 59 pivotally supported on the machine frame 3, the base end of one of the arms 56 of the holding finger 52 of the other side (the right side) is linked to an auxiliary lever 61 supported by a pivot 60 to the machine frame 3, and a cam follower 62 pivotally mounted to the base curved portion of the auxiliary lever 61 is urged by a spring 64 to contact the surface of a cam 63 on the same shaft as the cam 59.
Accordingly, because of the action of the spring 64 when the holding finger 52 comes into contact with the banknotes P, it is possible to correspond to banknotes P of different thicknesses.
One oE the holding surfaces of the holding fingers 52,53 has, as shown in FIG. 9, a protrusion surface 52a on 2~26 which there are circular protrusions, and the other of the holding surfaces of the holding fingers 52,53 has a recess surface 53a on which there are circular recesses corresponding to the circular protrusions in the protrusion 5 surface 52a, so that when banknotes P are held between the holding fingers 52,53, they bent along its long direction and do not slip even when they are held from one side only.
A lift mechanism 66 of a machine base 65 that supports these holding fingers 52,53 has, as indicated in FIG. 9, is supported by a shaft 67 having a non-circular cross section and which has its upper and lower ends supported by the machine base 65 so that it cannot rotate, and a pulley 71 is rotated by a motor 68 on the machine frame 3 via a worm gear 69 and a worm wheel 70, and a belt 73 is wound around the pulley 71 and a pulley 72 pivotally supported towards the bottom of the machine frame 3, with the belt 73 and the machine base 65 being linked by a linking member 74 so that the rotational movement of the belt 73 raises and lowers the machine base 65.
A belt 77 is wound around a pulley 75 that rotates by the rotation of the motor 68, and a pulley 76 on the shaft 67 and a belt 81 is wound around another pulley 78 on the shaft 67 and a pulley 80 on a shaft 79 of the cams 59 and 63 mentioned above, so that it applies a rotational motion to these cams so that the cam shape of these cams 59,63 moves the holding fingers 52,53 in the direction whereby the come together, and in the direction where they return to the position indicated in FIG. 8.
In addition, as shown in FIG. 8, towards the bottom of the shaft 67 are provided a detector plate 67a and a detection sensor S6 in order to detect the rotational position of the shaft 67, and these detect the holding position and the opening position of the holding fingers 52,53.
The machine frame 3 is provided with sensors S1, S2 and S3 that detect the position of the machine base 65. Sensor S1 detects the standby position (the position indicated in 2 ~
FIG. 3), the sensor S2 detects the position where the stacking portion 11 holds the banknotes P and the sensor S3 detects the position where the movement to the bundling position A stops.
As indicated in FIG. 3 and FIG. 4, the clamping means 13 has left and right clamping members 82,83 shaped like a letter C, when seen from above, and opposing each other, and the left and right clamping members 82,83 are disposed on the left and right sides of the bundling position A, so that position where the banknotes P are held by the holding fingers 52,53 is maintained at a position close to the opposite end.
One of the clamping members 82 (the left clamping member in the diagram) is supported so that it guides guide shafts 84,85 provided on the machine frame 3 and freely advances towards and retreats from the bundling position A, and the base end at the bottom of the machine frame 3 is linked with play by a long hole 88 and a pin 87 to the top end of a lever 86 that is pivotably supported, and a cam follower 89 pivotably attached along the lever 86 receives an urging force of a spring and contacts the surface of a cam 90, so that the rotational motion of this cam causes the clamping member 82 to freely advance and retreat along the guide shafts 84,85.
In this embodiment, a stamp 91 is built into the clamping member 82 and the stamp 91 freely advances and retreats along the guide shafts 92,93, and the upper end of a lever 94 pivotable supported on the same shaft as the lever 86 is freely linked by a pin and a long hole. A cam follower 95 pivotably attached along the lever 94 receives the urging force of a spring and is brought into contact with the surface of another cam 96 on the same shaft. The shape of the cam 96 causes the stamp 91 to advance for a predetermined time as will be described later, and to perform a stamping operation.
The clamping member 83 on the other side (the right side in the diagram) is escapably supported by springs 2~2~
99,100 so that it freely advances and retreats along the guide shafts 97,98 provided to the machine frame 3, in the direction of the bundling position A , and a base portion towards the bottom of the machine frame 3 is linked with play by a pin 102 and a long hole 103, so that a cam follower 104 pivotable attached along this lever 101 receives an urging force of a spring and is brought into contact with the surface of a cam 105. The shape of the cam 105 is such that the clamping member 83 advances to slightly ahead of the clamping member 82 previously described.
To an upper portion of the C-shaped inner portion of the clamping member 83 are fixed tape guides 107 that have a C-shape when seen in plan, and on which guides 106,106 at the left and rlght dlstal ends open outwards as indicated in FIG. 10, and the width of the inside portion is slightly wider than the width of the tape T. In addition, the banknote P contact edges 83a,83a of the clamping member 83 have a width that extends in the longitudinal direction as indicated in FIG. 11 and have portions a,a opposing contact edges 82a,82a of the clamping member 82, and which have positions b,b opposing both side portions of 108 which is to be described later. Accordingly, the portions a,b can be formed by being the end of the clamping member 83 at right angles. However, as indicated in FIG. 12, a separate member 109 can be fixed to the inner side of the clamping member 82 and the opposing portions b,b formed as the contact edges 83a,83a.
As indicated in FIG. 3 and FIG. 4, the tape supply means 14 has a flat tape passage 111 to guide the tape T
led via intermediate reels 110,110,,, from a tape reel (not indicated in the figure), and a leading end of the passage 111 is open in the direction of the bundling position A, and of the upper and lower rollers 112,113 that are tape supply rotating bodies at the trailing end of this passage 111, the roller 113 (or a belt) is rotatably driven by a pulse motor 114 so that it can be driven in the forward and 2 ~
reverse directions, and so the tape T is fed out by the necessary amount and so that if necessary, the motor can be reversed to apply a tension to the tape T. In the vicinity of the leading end of the tape passage 111 is provided a sensor S4 to detect the leading end position of the tape T.
As indicated in FIG. 13, the tape winding means 15 has a movable holding member 116 and a fixed holding member 115 that holds the fed out end of the tape T, and the holding members 115,116 advance and retreat and swivel so as to describe an arc path indicated by the letter B in FIG. 3, at the bundling position A.
The fixed holding member 115 is provided fixed to the distal end of a swivel arm 119 supported so as to be freely rotatable by a shaft 118 to a moving frame 117, and the movable holding member 116 has a structure that opens and closes with respect to the fixed holding member 115 supported by a shaft 120 to the previously mentioned swivel arm 119, and a spring 121 fitted between its base end and a swivel arm 119 urges the distal ends of both holding members 115,116 to close. In addition, the curved end of the base portion of the movable holding member 116 has a cam follower 122 pivotably attached to it and the cam follower 122 is provided so as to be in free contact with a cam portion 124 of a cam member 123 provided to the side of ~5 the machine frame 3, so that when the cam follower 122 rides onto the cam member 124 (the status indicated in FIG.
13), the distal end of the movable holding member 116 is separated from the distal end of the fixed holding member 115.
The cam member 123 is rotatably supported inside its horizontal surface by a shaft 125 on the side of the machine frame 3, and the cam member 123 is linked via a linkage lever 128 with a plunger 127 of a solenoid 126, so that when the plunger 127 is contracted, the cam member 124 is guided by a roller 130 on the side of the machine frame 3 and which engages with a curved long hole 129, and is swivelled in the anticlockwise direction (the direction of 2 ~
the arrow, in FIG. 13) around the center of the shaft 125.
The moving frame 117 that supports the holdi.ng members 115,116 is supported so as to freely advance and retreat along guide shafts 131,131 fixed to the machine frame 3, and a gear 132 is pivotably attached to the moving frame 117, with the direction of motion of the moving frame 117 being the direction of the shaft.
The mechanism that retreats the moving frame 117 has one end of a lever 136 pivotably and eccentrically attached with respect to a shaft 134 of a member 135 fixed to the shaft 134 of a motor 133 mounted to the machine frame 3, and the other end of the lever 136 is linked to the moving frame 117 by one end of a -;ocker arm 138 pivoted by a shaft 137, and a long hole 139 on the other side of the rocker arm 138 engages with a pin 140 of the moving frame 117, so that the motor 133 advances and retreats the moving frame 117 by a predetermined stroke, via the lever 136 and the rocker arm 138.
The gear 132 engages with a long gear 141 having elongated teeth and which is pivotably supported on the side of the machine frame 3 and is status of engagement of the gears 132,141 is maintained even when the moving frame 117 is advanced or retreated. In addition, the gear 141 on the side of the machine frame 3 transmits the rotation of a motor 142 via a timing belt 143. Moreover, Ss is a rotation detection sensor and 144 is a detection plate having a detection portion 145.
As shown in FIG. 14 and FIG. 15, the cutter mechanism 16 cuts the tape T by swiveling when a solenoid 148 moves a cutter arm 147 having a blade perpendicularly attached at its distal end, downwards and the lever mechanism is provided between a plunger 149 and the cutter arm 147 so as to increase the swivel angle of a blade 146 with respect to the stroke of the plunger 149 of the solenoid 148. This lever mechanism links one end of a short lever 152 to one end of an L-shaped lever 151 pivoted at its bend by a shaft 150 on the machine frame 3, and the other end of the lever ~2~j6 152 is linked at a position close to a pivot shaft 153 of the cutter arm 147, so that when the plunger 149 is contracted, the L-shaped lever 151 rotates about the center of the pivot 150 in the clockwise direction indicated in the figure, the short lever 152 is raised, and the cutter arm 147 rotates about the center of the pivot 153 and swivels a large distance in the clockwise direction indicated in the figure.
As shown in FIG. 3, the thermal bonding pad mechanism 17 has a lever 156 pivotably attached to the lower end of an arm 155 to which one end is pivoted by a shaft 154 to the machine frame 3, and is at a constant position with respect to the arm 155 that is drawn by a spring 157, and the lever 156 has a thermal bonding pad mounted to it. Cam followers 159,160 pivotably mounted along the arm 155 receive the urging force of the spring 157 and are successively brought into contact with the cam surface, and the rotation of a cam 161 swivels so that a thermal bonding pad 158 swivels in the direction of the bundling position A, and in the diagram, the clamping means 13 enters from the bottom into the clamping member 82 on the left side.
A separate pressing-down lever 162 is mounted to the shaft 154 of the arm 155 as the means to press the tape T, and a receiving portion 163 at its distal end contacts the lower end of the tape T that is wound around the banknotes P at the bundling position A, and is structured so that the tape T does not slacken.
The following is an explanation of the operation of the embodiment described above.
In FIG. 1 and FIG. 2, the banknotes P that are to be bundled are placed on the hoper 6 of the bundling machine 1, so that pressing the start button takes the banknotes one at a time into the inlet means (not indicated in the diagram). The banknotes P that have been taken in are identified by the identification means 8 as to whether or not they are banknotes P suitable for bundling, and if they are suitable, are sent to the stacking portion 11 via the 2~
conveyor path 9, and if they are banknotes P of differing denominations, counterfeit banknotes or doubly fed banknotes that are not suitable for bundling, then the a signal ~rom the identification portion 8 switches the separation fingers 10 and the unsuitable banknotes P are returned to the reject portion 7. The banknotes P that are sent to the stacking portion 11 are sent to the receiving portion 18 after having been taken in one at a time between the vanes 30,30,,, of the vane wheels 26,26,,, and are left on the bottom portion 24 where they are successively collated and aligned in an upright position.
During this time, the round aligning rod 42 is intermittently driven by the long side alignment mechanism 32 so that it swivels and strikes one of the long ends of the banknotes P while the other of the long ends of the banknotes P is pressed against the fixed wall 31 so that the edges of the banknotes P are aligned. In addition, at the same time, the short-direction alignment mechanisms 43,43 intermittently operate and their alignment members 46,46 swivel and press the upper edge of the banknotes P
with the alignment portion 46a so that the edges of the banknotes P are aligned in the short direction.
As indicated in FIG. 16A through FIG. 16K, when a predetermined number of banknotes P (customarily 100) are stacked in the aligned status in the stacking portion 11, the driving of the motor 68 of the holding and transfer means 12 causes the machine base 65 to rise because of the belt 73 and the left and right holding fingers 52,53 rise in the open status and proceed to positions between the center and the short ends of the banknotes P in the stacking portion 11, where they holding fingers 52,53 close by the rotation of the cams 59,60 that are rotated by the motor 68, and hold the banknotes P between them (See FIG.
16A).
After the banknotes P have been held, the rotation of the cam 23 rocks the rocker lever 20 around the pivot 21 and in the clockwise direction as indicated in the FIG.
4 ~ ,3 16B, and the receiving portion 18 retreats from the lower portlon of the banknotes P while at the same time, the motor 142 of the tape winding means 15 is driven and swivels the swivel arm 119 through the gears 141,132, so that the cam follower 112 of the movable holding member 116 falls from the cam follower 124, the movable holding member 116 is closed by the urging force of spring 121, and the end of the tape T protrudes from the distal end of the tape passage 111 between the distal ends of the fixed holding member 115 and the movable holding member 116, and is held.
After this, the swivel arm 119 rotates further and stops once at the position as shown in FIG. 16C, which is approximately three quarters of the range of motion. By this, the tape T that has been drawn out is lowered, slackened and drawn at the bundling position A, across the banknotes P. Then, the machine base 65 of the holding and transfer means 12 lowers once again and the banknotes P are moved to the bundling position A (See FIG.16D). I'he presser plate 27 of the stacking portion 11 advances since i-t holds no banknotes P, and returns to the position where it is in contact with the outer surface of the vane wheels 26,26,...
Then, one of the clamping members 83 having a tape guide 107 for the clamping means 13 advances prior to the other (See FIG.16E), and the tape T on the side of the end that is held by and drawn out from the tape winding means 15 is led to between the guides 106,106 of the tape guide 107, and the position of the tape T controlled.
After this, the holding members 115,116 rotate further, and winds the tape T around the banknotes P but at this time, when the tape T passes the leading edge tape passage 111 of the tape supply means 14, that is, when the tape T
passes a predetermined position shown in FIG. 16A, the cam follower 122 of the movable holding member 116 rides up on the cam portion 124 and cancels the holding of the tape T
50 that when it passes a second time, the solenoid 126 operates and the cam member 123 is drawn to release the cam 2a~"
portion 124. The cam follower 122 of the movable holding member 116 does not interfere with the cam portion 124 even when it rotates and therefore allows the tape T to pass while holding it. Then, the tape winding means 15 stops when the holding members 115,116 have rotated more than once and have come to a position where the tape T is partially overlapped (See FIG. 16F). After this, the pulse motor 114 of the tape supply means 14 rotates in reverse for a predetermined time, and a tension is applied to the Tape T. When this occurs, when the friction between the tape surface and the roller 113 causes the tension of the tape T to reach a certain amount, the roller 113 slips and so the tape T binds the banknotes P at a constant force.
After this, the reversing of the pulse motor 114 by a predetermined number of pulses feeds out a constant amount of the tape T so that the binding force of the tape T is decreased slightly.
Then, the cam 161 of the mechanism 17 rotates and the arm 155 is rotated about the center of the pivot 154, in the clockwise direction in the diagram, and the receiving portion 163 of the bottom support lever 162 contacts and presses against the lower edge corner portion of the tape T
that is wound around the banknotes P, and the thermal bonding pad 158 enters into the clamping member 82 and contacts the overlapping portion of the tape T that was wound first (See FIG. 16G), and starts the thermal bonding of the tape T.
After this, the motor 114 of the tape supply means 14 rotates in the forward direction for a predetermined number of pulses, and the tape T is slackened, the cutter mechanism 16 operates and the cutter 146 contacts the tape T (See FIG. 16H) and performs cutting. After cutting, the thermal bonding pad 158 proceeds further and thermally bonds the cut ends of the tape T (See FIG. 16I).
After the tape has been cut, the motor 133 of the tape tape winding means 15 is driven and moving frame 117 is retreated via the lever 136 and the rocker arm 138 (to the 2~2~L.~.3v left in FIG. 13~, so that the gear 132 slides while it is still engaged with the gear 141 and draws back the shaft 118, the holding members 115,116 are pulled back and the pull from the bottom of the tape T that is wound around the banknotes P. After this, the stamp 91 advances and presses a predetermined seal on the surface of the tape T.
After the adhering of the tape T has been completed, the iron 158 returns (See FIG. 16J), and at the same time, the holding fingers 52,53 of the holding and transfer means 12 separate and cancel the holding of the banknotes P, and then the clamping members 82,83 of the clamping means 13 separate and release the bundled banknotes P in the downwards direction, and all of the portions return to the statuses indicated in from FIG. 16A through FIG. 16K, and the bundled banknotes P are collected inside an appropriate receiving box.
The description for the embodiment indicated in the figures has been given in terms of a bundling apparatus but it is of course possible to apply the present invention for bundling of other than leaf paper, and the configuration of each of the portions is not necessarily limited to the embodiment indicated in the figures but can be subjected to appropriate design changes. In addition, the period for which there is thermal bonding of the tape T can start either after the tape has been cut, or the thermal bonding can start before the tape has been cut and further thermal bonding performed to bond the cut ends of the tape after the tape has been cut. Furthermore, the period for which the holding is cancelled can end either before or after the clamping of the leaf paper is cancelled.
The following is a description of another embodiment of the present invention, in which the leaf paper bundling apparatus performs only the bundling of banknotes.
In this embodiment, an operator takes a stack of collated and aligned banknotes by hand and inserts them to the bundling position A, holds them while they are being bundled and removes them by hand from the bundling position 1~
A after they have been bundled. In this manner, the operator holds the unbundled banknotes P by hand while the bundling operation is being performed and so there is no mechanism (the portions indicated by the numerals 6,7,8,9,10,11) for the stacking portion 11 and upstream and there is no holding and transfer means 12 but the other portions of the configuration (the portions indicated by 13,14,15,16 and 17) are all the same as for the previous configuration.
A specific example of this embodiment is indicated in FIG. 17 and FIG. 18 and in this embodiment, there is a banknote insertion and holding device 200 that has the same configuration as the portions (13,14,15,16,17) of the other configuration already described This banknote insertion and holding device 200 has a banknote insertion inlet 201 with a width larger than the thickness of the unbundled banknotes P' and the banknote insertion inlet 201 has its top portion open so that the unbundled banknotes P' can be inserted by dropping them in from above. The bottom end portion of the unbundled banknotes P' that are inserted into this banknote insertion inlet 201 are pressed by a back stopper 202 that determines the insertion position. This back stopper 202 is fixed by a fixed rotating arm 204 to a rotational drive shaft 203 and its position at the time when unbundled banknotes P' have been inserted into the banknote insertion inlet 201 and the machine is in the standby status, is the position that is indicated in FIG. 18 but when the tape tape winding means 15 is rotating, the back stopper 202 retreats by the rotation through a predetermined angle of rotation by the rotational drive shaft 203 and the rotating arm 204 so that it does not interfere with the tape winding means 15.
Accordingly, in this embodiment, the motor lg2 of the tape tape winding means 15 starts by the manual operation of a set switch provided separately to the power switch, and the tape tape winding means 15 that holds the tape T
moves from a position (B) (in FIG. 16) to the position -indicated in FIG. 17 and stops. Moreover, this status indicated in FIG . 17 corresponds to the status indicated in FIG. 16C, and the position of the tape winding means 15 is the same as position in FIG. 16C and the position in FIG.
17. Immediately after, the back stopper 202 rotates from its retreated position and stops at the position indicated in ~IG. 18.
In this status, the unbundled banknotes P~ (customarily 100 in the case of banknotes) are inserted to the banknote insertion inlet 201 while they are being held by the operator. In this case, the unbundled banknotes P' are inserted to a position slightly above the inside of the banknote insertion inlet 201 (i.e. a position indicated by the double-dotted line in FIG. 17, that is to say, the upper position not in contact with the tape T) and the end portion of the unbundled banknotes P' is pushed against the back stopper 202.
Then, while the unbundled banknotes P' are being held manually, and lowered along the opening edge 201a of the banknote insertion inlet 201, they unbundled banknotes P~
are held in the status (the status indicated in FIG . 17 and FIG. 18) where they are in contact with this opening edge 201a (corresponding to the status indicated in FIG. 16D).
At this time, there is a slight gap between the unbundled banknotes P~ and the opening edge 201c.
When the lower edge of the unbundled banknotes P' comes into contact with the opening edge 201b, a detector switch (not indicated in the figure) detects the unbundled banknotes P' and the back stopper 202 moves to the retreat position.
Then, the clamping member 83 which is the clamping member that has the tap guide 107 of the clamping means 13 advances first and the operations indicated in FIG.
16F,G,H,I,J and K are performed and the clamping members 82,83 separate. This separation of the clamping members 82,83 is indicated to the operator by a lamp for example, and the operator pulls out the bundled banknotes from the 2 ~
banknote insertion inlet 201. This pulling out of the bundled banknotes is detected by a detection means (not indicated in the figure) and the operations corresponding to of FIG. 16~ and FIG. 16C are performed and the tape winding means 15 is placed in the position indicated in FIG. 17. The rotation of the rotational drive shaft 203 causes the back stopper 202 to proceed once again from the retreat position to the position indicated in FIG. 18 and the device enters the standby status for the insertion of the next stack of unbundled banknotes P'.
In this manner, the present invention can perform bundling even if the unbundled banknotes P' are held by hand.
According to the first embodiment as has been described above, in the bundling position, there is a structure that winds tape around the leaf paper at a position where the leaf paper is not being held, and that also uses a first and a second clamping members in the vicinity of that winding position to compress and hold the leaf paper, with a tension being applied to the tape in the status where the leaf paper is being held by the left and right contact edges of these first and second clamping members, so that the tape is cut and thermally bonded by a thermal bonding pad iron and without the necessity to wind the tape around the holders as is the case for the conventional device.
There is also the effect of being able to remove the bundled leaf paper by simply releasing the hold by the clamping members after bundling and so there are no process that damage the leaf paper, resulting in a neat bundle. In addition, each of the clamping members have left and right contact edges which compress and hold the lead paper so that it is possible to tightly compress the leaf paper at the position where it is to be bound and therefore achieve bundling without any slackening of the tape.
In addition, according to the second embodiment, the length of the contact edges of the clamping members is larger than the width of the leaf paper in the direction of 2 ~ r3 ',~
winding the tape and the leaf paper is held in the status where the edge portions of the contact edges protrude past the leaf paper and so in addition to the effect described above, there is the additional effect of preventing the ends of the paper from being bent and pulled down when the tape is wound around the leaf paper, so that there is no damage to the bundled leaf paper and a neat bundle is produced.
While the presently preferred embodiments of the present invention have been shown and disclosed, it is to be understood that this disclosure is for the purpose of illustration and that various changes and modifications may be made without departing from the scope of the invention as set forth in the appended claims.
I
After this, the swivel arm 119 rotates further and stops once at the position as shown in FIG. 16C, which is approximately three quarters of the range of motion. By this, the tape T that has been drawn out is lowered, slackened and drawn at the bundling position A, across the banknotes P. Then, the machine base 65 of the holding and transfer means 12 lowers once again and the banknotes P are moved to the bundling position A (See FIG.16D). I'he presser plate 27 of the stacking portion 11 advances since i-t holds no banknotes P, and returns to the position where it is in contact with the outer surface of the vane wheels 26,26,...
Then, one of the clamping members 83 having a tape guide 107 for the clamping means 13 advances prior to the other (See FIG.16E), and the tape T on the side of the end that is held by and drawn out from the tape winding means 15 is led to between the guides 106,106 of the tape guide 107, and the position of the tape T controlled.
After this, the holding members 115,116 rotate further, and winds the tape T around the banknotes P but at this time, when the tape T passes the leading edge tape passage 111 of the tape supply means 14, that is, when the tape T
passes a predetermined position shown in FIG. 16A, the cam follower 122 of the movable holding member 116 rides up on the cam portion 124 and cancels the holding of the tape T
50 that when it passes a second time, the solenoid 126 operates and the cam member 123 is drawn to release the cam 2a~"
portion 124. The cam follower 122 of the movable holding member 116 does not interfere with the cam portion 124 even when it rotates and therefore allows the tape T to pass while holding it. Then, the tape winding means 15 stops when the holding members 115,116 have rotated more than once and have come to a position where the tape T is partially overlapped (See FIG. 16F). After this, the pulse motor 114 of the tape supply means 14 rotates in reverse for a predetermined time, and a tension is applied to the Tape T. When this occurs, when the friction between the tape surface and the roller 113 causes the tension of the tape T to reach a certain amount, the roller 113 slips and so the tape T binds the banknotes P at a constant force.
After this, the reversing of the pulse motor 114 by a predetermined number of pulses feeds out a constant amount of the tape T so that the binding force of the tape T is decreased slightly.
Then, the cam 161 of the mechanism 17 rotates and the arm 155 is rotated about the center of the pivot 154, in the clockwise direction in the diagram, and the receiving portion 163 of the bottom support lever 162 contacts and presses against the lower edge corner portion of the tape T
that is wound around the banknotes P, and the thermal bonding pad 158 enters into the clamping member 82 and contacts the overlapping portion of the tape T that was wound first (See FIG. 16G), and starts the thermal bonding of the tape T.
After this, the motor 114 of the tape supply means 14 rotates in the forward direction for a predetermined number of pulses, and the tape T is slackened, the cutter mechanism 16 operates and the cutter 146 contacts the tape T (See FIG. 16H) and performs cutting. After cutting, the thermal bonding pad 158 proceeds further and thermally bonds the cut ends of the tape T (See FIG. 16I).
After the tape has been cut, the motor 133 of the tape tape winding means 15 is driven and moving frame 117 is retreated via the lever 136 and the rocker arm 138 (to the 2~2~L.~.3v left in FIG. 13~, so that the gear 132 slides while it is still engaged with the gear 141 and draws back the shaft 118, the holding members 115,116 are pulled back and the pull from the bottom of the tape T that is wound around the banknotes P. After this, the stamp 91 advances and presses a predetermined seal on the surface of the tape T.
After the adhering of the tape T has been completed, the iron 158 returns (See FIG. 16J), and at the same time, the holding fingers 52,53 of the holding and transfer means 12 separate and cancel the holding of the banknotes P, and then the clamping members 82,83 of the clamping means 13 separate and release the bundled banknotes P in the downwards direction, and all of the portions return to the statuses indicated in from FIG. 16A through FIG. 16K, and the bundled banknotes P are collected inside an appropriate receiving box.
The description for the embodiment indicated in the figures has been given in terms of a bundling apparatus but it is of course possible to apply the present invention for bundling of other than leaf paper, and the configuration of each of the portions is not necessarily limited to the embodiment indicated in the figures but can be subjected to appropriate design changes. In addition, the period for which there is thermal bonding of the tape T can start either after the tape has been cut, or the thermal bonding can start before the tape has been cut and further thermal bonding performed to bond the cut ends of the tape after the tape has been cut. Furthermore, the period for which the holding is cancelled can end either before or after the clamping of the leaf paper is cancelled.
The following is a description of another embodiment of the present invention, in which the leaf paper bundling apparatus performs only the bundling of banknotes.
In this embodiment, an operator takes a stack of collated and aligned banknotes by hand and inserts them to the bundling position A, holds them while they are being bundled and removes them by hand from the bundling position 1~
A after they have been bundled. In this manner, the operator holds the unbundled banknotes P by hand while the bundling operation is being performed and so there is no mechanism (the portions indicated by the numerals 6,7,8,9,10,11) for the stacking portion 11 and upstream and there is no holding and transfer means 12 but the other portions of the configuration (the portions indicated by 13,14,15,16 and 17) are all the same as for the previous configuration.
A specific example of this embodiment is indicated in FIG. 17 and FIG. 18 and in this embodiment, there is a banknote insertion and holding device 200 that has the same configuration as the portions (13,14,15,16,17) of the other configuration already described This banknote insertion and holding device 200 has a banknote insertion inlet 201 with a width larger than the thickness of the unbundled banknotes P' and the banknote insertion inlet 201 has its top portion open so that the unbundled banknotes P' can be inserted by dropping them in from above. The bottom end portion of the unbundled banknotes P' that are inserted into this banknote insertion inlet 201 are pressed by a back stopper 202 that determines the insertion position. This back stopper 202 is fixed by a fixed rotating arm 204 to a rotational drive shaft 203 and its position at the time when unbundled banknotes P' have been inserted into the banknote insertion inlet 201 and the machine is in the standby status, is the position that is indicated in FIG. 18 but when the tape tape winding means 15 is rotating, the back stopper 202 retreats by the rotation through a predetermined angle of rotation by the rotational drive shaft 203 and the rotating arm 204 so that it does not interfere with the tape winding means 15.
Accordingly, in this embodiment, the motor lg2 of the tape tape winding means 15 starts by the manual operation of a set switch provided separately to the power switch, and the tape tape winding means 15 that holds the tape T
moves from a position (B) (in FIG. 16) to the position -indicated in FIG. 17 and stops. Moreover, this status indicated in FIG . 17 corresponds to the status indicated in FIG. 16C, and the position of the tape winding means 15 is the same as position in FIG. 16C and the position in FIG.
17. Immediately after, the back stopper 202 rotates from its retreated position and stops at the position indicated in ~IG. 18.
In this status, the unbundled banknotes P~ (customarily 100 in the case of banknotes) are inserted to the banknote insertion inlet 201 while they are being held by the operator. In this case, the unbundled banknotes P' are inserted to a position slightly above the inside of the banknote insertion inlet 201 (i.e. a position indicated by the double-dotted line in FIG. 17, that is to say, the upper position not in contact with the tape T) and the end portion of the unbundled banknotes P' is pushed against the back stopper 202.
Then, while the unbundled banknotes P' are being held manually, and lowered along the opening edge 201a of the banknote insertion inlet 201, they unbundled banknotes P~
are held in the status (the status indicated in FIG . 17 and FIG. 18) where they are in contact with this opening edge 201a (corresponding to the status indicated in FIG. 16D).
At this time, there is a slight gap between the unbundled banknotes P~ and the opening edge 201c.
When the lower edge of the unbundled banknotes P' comes into contact with the opening edge 201b, a detector switch (not indicated in the figure) detects the unbundled banknotes P' and the back stopper 202 moves to the retreat position.
Then, the clamping member 83 which is the clamping member that has the tap guide 107 of the clamping means 13 advances first and the operations indicated in FIG.
16F,G,H,I,J and K are performed and the clamping members 82,83 separate. This separation of the clamping members 82,83 is indicated to the operator by a lamp for example, and the operator pulls out the bundled banknotes from the 2 ~
banknote insertion inlet 201. This pulling out of the bundled banknotes is detected by a detection means (not indicated in the figure) and the operations corresponding to of FIG. 16~ and FIG. 16C are performed and the tape winding means 15 is placed in the position indicated in FIG. 17. The rotation of the rotational drive shaft 203 causes the back stopper 202 to proceed once again from the retreat position to the position indicated in FIG. 18 and the device enters the standby status for the insertion of the next stack of unbundled banknotes P'.
In this manner, the present invention can perform bundling even if the unbundled banknotes P' are held by hand.
According to the first embodiment as has been described above, in the bundling position, there is a structure that winds tape around the leaf paper at a position where the leaf paper is not being held, and that also uses a first and a second clamping members in the vicinity of that winding position to compress and hold the leaf paper, with a tension being applied to the tape in the status where the leaf paper is being held by the left and right contact edges of these first and second clamping members, so that the tape is cut and thermally bonded by a thermal bonding pad iron and without the necessity to wind the tape around the holders as is the case for the conventional device.
There is also the effect of being able to remove the bundled leaf paper by simply releasing the hold by the clamping members after bundling and so there are no process that damage the leaf paper, resulting in a neat bundle. In addition, each of the clamping members have left and right contact edges which compress and hold the lead paper so that it is possible to tightly compress the leaf paper at the position where it is to be bound and therefore achieve bundling without any slackening of the tape.
In addition, according to the second embodiment, the length of the contact edges of the clamping members is larger than the width of the leaf paper in the direction of 2 ~ r3 ',~
winding the tape and the leaf paper is held in the status where the edge portions of the contact edges protrude past the leaf paper and so in addition to the effect described above, there is the additional effect of preventing the ends of the paper from being bent and pulled down when the tape is wound around the leaf paper, so that there is no damage to the bundled leaf paper and a neat bundle is produced.
While the presently preferred embodiments of the present invention have been shown and disclosed, it is to be understood that this disclosure is for the purpose of illustration and that various changes and modifications may be made without departing from the scope of the invention as set forth in the appended claims.
