Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a dispensing device for automatically feeding sheet-like products one by one.
More specifically, the present invention relates to a dispensing device that sends out sheet-like products each containing card-like products in a sheet-like bag formed of a thin film.
More specifically, the present invention relates to a payout device for sending out a sheet-like product containing cards in which cards are enclosed in a sheet-like bag one by one.
[0002]
The “sheet-like product” used in this specification includes a product in which a product is enclosed in a sheet-like bag, a card, and the like.
The “sheet-like bag” is an envelope-like bag made of resin, aluminum foil, paper, or the like and having substantially no air permeability.
“Cards” include telephone cards, prepaid cards, character cards, bromides, IC cards, and the like.
[0003]
[Prior art]
The present applicant has proposed a technique disclosed in US Pat. No. 6311867 and Japanese Patent Application Laid-Open No. 2001-118137 in order to pay out the stacked card-like products without damage. The prior art will be described below.
The uppermost stacked sheet-like product is sucked by the suction device and then sent out by the transporting device in contact by suction.
After the uppermost sheet-like product is paid out, the stacked sheet-like product is pushed up.
When the uppermost sheet-like product is detected by the sensor, the push-up is stopped, the distance between the uppermost sheet-like product and the suction device is made constant, and the next payout is prepared.
[0004]
The reason why the distance between the uppermost sheet-like product and the suction device is constant is that after the uppermost sheet-like product is dispensed, the next sheet-like product is sent out by the suction device and the conveying device that are operated by inertia. This is to prevent this.
Next, when a sheet-like product payout signal is received, the suction device is operated to suck the sheet-like product, and the sheet-like product is paid out in the same manner as described above.
[0005]
By the way, in the sheet-like product 1 in which the card 1C is enclosed in the sheet-like bag 1B formed of the thin film shown in FIG. 6, the air remains in the inside or the sheet joint exists in the central portion, Specifically, it has a pillow shape with a bulging center.
Therefore, when a large number of sheet-like products 1 are stacked, the uppermost sheet-like product 1 is necessarily inclined in the longitudinal direction or the width direction.
[0006]
As described above, the position of the uppermost sheet-like product 1 is detected and controlled by a sensor so that the distance from the suction device is appropriate.
However, even if the position of a part of the sheet-like product 1 detected by the sensor is appropriate, the distance between the other part and the suction device may be larger than the appropriate value due to the inclination.
For this reason, the uppermost sheet-like product 1 may not be adsorbed by the suction device.
[0007]
In addition, when the sheet-like product 1 is adsorbed by the suction device, the sheet-like product 1 is quickly sucked up, and thus an adhesive force is generated due to the negative pressure generated between the lower sheet-like product 1 that is in close contact therewith. , May be sucked together.
As a result, two sheets of the sheet-like product 1 are generated.
[0008]
[Problems to be solved by the invention]
A first object of the present invention is to ensure that a sheet-like product is paid out.
The second object of the present invention is to prevent two sheets of sheet-like products from being put out.
A third object of the present invention is to provide a sheet dispensing apparatus at low cost.
[0009]
[Means for Solving the Problems]
In order to achieve this object, the present invention provides a table that can be moved up and down by placing a sheet-shaped bag in which a product is enclosed in a bag, and a downward-facing table that is positioned above the table and that adsorbs the sheet-shaped bag. A suction device including a suction airflow generation device that generates an upward airflow at the suction port by rotation of a fan connected to the suction port and an output shaft of an electric motor, and disposed below the suction port and lower than the suction port A position sensor that outputs an upper position signal when the contact is pushed up, and a first that conveys the sheet-shaped bag adsorbed to the suction port in a direction transverse to the suction direction. Positioned on a transporting device, a second transporting device that receives the sheet-like bag transported by the first transporting device and transports it to a lateral outlet, and a movement path of a sheet-like product corresponding to the second transporting device And a payout detection sensor that detects the passage of the sheet-like bag and outputs a passage signal, an elevating device that moves the table close to and away from the suction port, and an electric motor based on the payout signal. In an automatic dispensing device comprising a control device that operates to adsorb the sheet-like bag and then lowers the table by the lifting device and separates it from the suction port by a predetermined distance or more, the control device further includes the sheet-like bag The operation of the electric motor is stopped based on the output of the passage signal of the sheet-like bag by the payout detection sensor, and the transport function by the first transport device and the second transport device is stopped. device actuates the raising of the sheet bag, the stop the upward movement of the lifting device by an output of said on position signals of the position sensor, the sheet Bag is obtained by an automatic dispensing device for the sheet-like pouch, characterized in that to stop the standby position which can be sucked into the suction port.
[0010]
In this configuration, the sheet-like product is brought close to the suction device by the table, and the sheet-like product at the extreme end position is attracted by the operation of the suction device.
Based on the payout signal, the suction device is operated, and the end-most sheet-like product is adsorbed by the suction device.
Thereafter, the table is separated from the suction device by a predetermined distance by the moving device.
Therefore, the sheet-like product sucked by the suction device and the outermost sheet-like product supported by the table are completely separated.
[0011]
At this time, since the movement of the table, and hence the movement of the sheet-like product supported by the table, is low speed, no adhesion due to negative pressure is generated between the adsorbed sheet-like product and the table-like product is supported by the table. The sheet-like product that is present leaves the suction device as the table moves.
In this state, the transport device is operated, and the sheet-like product adsorbed by the suction device is dispensed.
[0012]
After the sheet-like product is paid out, the moving device is operated and the table is moved so that the outermost sheet-like product is located in the suction range of the suction device, and prepares for the next payout.
As a result, only the outermost sheet-like product is paid out by the transport device.
[0013]
The present invention preferably includes the suction device and the transport device fixed to one side of the sheet-like product, and a moving device that moves the table positioned on the other side of the sheet-like product to the suction device side. .
In this configuration, the suction device and the transport device including the rotating means are fixed, and the sheet-like product to be dispensed is kept at a predetermined distance from the suction device by the moving device.
Therefore, since the suction device or the transport device having a complicated mechanism is not moved, the structure is simplified, the failure and the maintenance are minimized, and the cost is low.
[0014]
The present invention preferably includes an electric motor in which the moving device is rotated in one direction by the control device and then rotated in the opposite direction.
In this configuration, the movement direction of the moving device that controls the position of the sheet-like product is changed depending on the rotation direction of the electric motor.
In other words, the interval between the sheet-like product and the suction device is changed depending on the rotation direction of one electric motor.
Therefore, since the distance between the sheet-like product and the suction device can be changed by changing the rotation direction of the electric motor, the configuration is simple and inexpensive.
[0015]
The present invention includes a table on which a sheet-like product can be placed and movable in a vertical direction, a suction device that is located above the table and sucks the sheet-like product, and the sheet-like product sucked by the suction device. A transporting device that transports in a direction transverse to the suction direction; and a control device that operates the suction device based on a payout signal to suck a sheet-like product and then lowers the table away from the suction device. Is preferred.
[0016]
In this configuration, since the sheet-like product is located on the table by gravity, the distance from the suction device is controlled by the movement of the table.
Based on the payout signal, the suction device is operated and the uppermost sheet-like product is adsorbed by the suction device, and then the table is lowered by the control device and separated from the suction device.
Thereby, the sheet-like product adsorbed by the suction device and the sheet-like product on the table are completely separated.
[0017]
Next, the conveying device is operated, and the adsorbed sheet-like product is shifted laterally by the conveying device and dispensed.
Therefore, since the position of the sheet-like product is determined according to the movement of the table by its weight, the structure is simple, the size can be reduced, and the price is low.
[0018]
In the present invention, it is preferable that the control device includes a pre-control device that lowers the table by a predetermined amount after the operation of the suction device.
In this configuration, the sheet-like products are stacked in the vertical direction on the table.
The suction device is activated and the uppermost sheet-like product is adsorbed to the suction device.
[0019]
Thereafter, the table is moved downward by the lifting device, and the sheet-like product placed thereon is also moved downward by gravity, so that the adsorbed sheet-like product and the sheet-like product on the table are separated. Is done.
Thereafter, the transport device is activated, and the sheet-like product adsorbed by the suction device is dispensed by the transport device.
Therefore, the structure is simple, the size can be reduced, and the price is low.
[0020]
In the present invention, it is preferable that the control device controls the lifting device so as to raise the table to a predetermined position after the sheet-like product is dispensed by the transport device.
In this configuration, after the sheet-like product is paid out, the lifting device is operated, and the uppermost sheet-like product is moved to a position where it can be adsorbed by the suction device regardless of the state.
Therefore, when the payout signal is output next time, the suction device is operated immediately and the sheet-like product can be adsorbed in the same manner as described above, so that the payout operation is quickly performed.

[0022]
In FIG. 1, an automatic dispensing device 10 for a sheet-like product 1 includes a dispensing unit 11 and a storage unit 12.
As shown in FIG. 3, the payout unit 11 includes a payout unit 13 and a two-sheet discharge detection device 14.
The dispensing unit 13 includes a suction device 15 and a transport device 16.
[0023]
The suction device 15 has a function of adsorbing the sheet-like product 1 with a suction airflow.
The suction device 15 includes a guide tube 17 and a suction airflow generation device 18.
The guide tube 17 has a rectangular tube shape with a hollow portion extending in the vertical direction, and is fixed to the side frame 19.
The lower end opening of the guide tube 17 is the suction port 20.
[0024]
The suction airflow generation device 18 generates an airflow sucked from the suction port 20.
The suction airflow generation device 18 includes an electric motor 21 having a fan fixed to an output shaft.
The electric motor 21 is fixed to the upper end portion of the guide tube 17.
When the motor 21 rotates, an upward air flow is generated in the guide tube 17 by the fan, and air is sucked from the suction port 20.
The suction airflow generation device 18 can employ a method of generating a suction airflow by the ejector effect.
Further, the suction airflow generation device 18 may rotate the fan by an air motor.
[0025]
Next, the transport device 16 will be described.
The transport device 16 has a function of transporting the sheet-like product 1 adsorbed by the suction device 15 in the horizontal direction.
The transport device 16 includes a first transport device 22 disposed in the guide tube 17 and a second transport device 23 disposed on the side of the guide tube 17.
[0026]
The peripheral surface of the first transport device 22 projects slightly downward from the suction port 20 in order to transport the sheet-like product 1 adsorbed by the suction port 20 to the second transport device 23.
In the embodiment, the first transporting device 22 is a first roller 26 fixed to a rotating shaft 25 that is horizontally and rotatably attached to the side wall of the guide tube 17.
[0027]
The first roller 26 has a peripheral surface covered with rubber in order to reduce slippage with the sheet-like product 1.
The first transporting device 22 can use a belt that moves in the direction of the second transporting device 23 instead of a roller.
[0028]
The second transport device 23 transports the sheet-like product 1 sent from the first transport device 22 to the payout opening 24.
In the embodiment, the second transport device 23 includes a pair of rollers.
A second roller 28 is fixed to a second rotating shaft 27 that is rotatably supported by the side frame 19 and arranged in parallel with the rotating shaft 25.
The peripheral surface of the second roller 28 is covered with rubber in order to reduce slippage with the sheet-like product 1.
[0029]
A third roller 29 is disposed below the second roller 28.
The third roller 29 is rotatably attached to a shaft 32 supported at both ends by a lever 31 that can be rotated by a fixed shaft 30 fixed to the side frame 19.
The lever 31 is rotated by a spring (not shown) to bring the third roller 29 into contact with the second roller 28.
The second electric motor 32 is disposed above the rotary shaft 25 and the second rotary shaft 27 and is fixed to the side frame 19.
[0030]
A belt 33 is wound around a pulley fixed to the output shaft of the second electric motor 32 and a pulley fixed to the rotary shaft 25 and the second rotary shaft 27.
The belt 33 rotates counterclockwise in FIG.
The second transport device 23 may transport the sheet-like product 1 with the pair of belts interposed therebetween.
A payout detection sensor 34 is attached to the side of the second roller 28, and its contact 35 is located in the movement path of the sheet-like product 1.
[0031]
The two-sheet-out detecting device 14 outputs a two-sheet out signal when the lever 31 is at a predetermined position.
In other words, when two sheet-like products 1 are sandwiched between the second roller 28 and the third roller 29 at a time, the sensor 31 detects that the lever 31 is rotated more clockwise than usual. Then, a two-sheet output signal is output.
[0032]
A shutter 37 that is rotatably supported by the second fixed shaft 36 is disposed in a movement path between the second transport device 23 and the payout port 24.
The shutter 37 is normally rotated counterclockwise in FIG. 3 by a spring (not shown) and is positioned on the moving path of the sheet-like product 1.
When the sheet-like product 1 travels on the movement path, the shutter 37 is pushed by the sheet-like product 1 and is rotated clockwise to be removed from the movement path.
Then, the sheet-like product 1 reaches the payout opening 24.
[0033]
Next, the storage unit 12 for the sheet-like product 1 will be described.
The storage unit 12 includes a storage chamber 40 extending in the vertical direction, a table 41 for moving the sheet-like product 1, and a moving device 42 for the table 41.
The storage chamber 40 is a prismatic space that is surrounded by the side frame 19 and extends in the vertical direction below the suction device 15.
The lower end portion of the lid 43 is pivotably and detachably attached to the side frame 19, and the upper end portion is locked to the side frame 19 by the lock device 44.
The sheet-like product 1 is stacked on the table 41 with the lid 43 removed.
[0034]
The table 41 has a rectangular plate shape and is movable so as to approach and separate from the guide tube 17 below the guide tube 17 in the storage chamber 40.
That is, the table 41 is movable in the vertical direction.
The sheet-like product 1 on the table 41 is brought close to and separated from the guide tube 17 by the movement of the table 41.
The table 41 has a function of bringing the sheet-like product 1 close to and away from the suction device 15.
Therefore, if it has this function, another mechanism can be adopted.
[0035]
Next, the moving device 42 will be described.
The moving device 42 includes a driving device 45 and a transmission device 46.
The drive device 45 is disposed on the side of the suction device 15 and is fixed to the side frame 19, and a third electric motor 48 is fixed to the speed reducer 47 and drives the speed reducer 47. A driving gear (not shown) fixed to the output shaft of the speed reducer 47, a rotating shaft 49 rotatably supported by the side frame 19, and fixed to the rotating shaft 49 and meshes with the driving gear. It has a driven gear 50 and a gear 51 fixed to the left and right ends protruding from the side frame 19 of the rotating shaft 49 (the right gear is not shown).
[0036]
The drive device 45 has a function of moving the table 41 closer to or away from the suction device 15 via the transmission device 46.
Therefore, if it has this function, another mechanism can be adopted.
[0037]
Next, the transmission device 46 will be described.
The transmission device 46 having the same structure is arranged on the left and right sides of the side frame 19, and the structure of the left transmission device 46 shown in the figure will be described.
A lower end of a rack 53 is rotatably attached to a stay 52 protruding sideways from the table 41 by a pin 54.
[0038]
The rack 53 is molded from a flexible resin and has flexibility.
An intermediate portion of the rack 53 is engaged with the gear 51.
The back of the rack 53 is pushed by a pinch roller 55 that is rotatably supported by a fixed shaft 54 protruding from the side frame 19, and is kept in mesh with the gear 51.
The front end of the rack 53 is inserted into an inverted J-shaped pipe 56 fixed to the side surface of the side frame 19 and returned to the table 41 side.
By arranging the flexible rack 53 in a J or U shape, the transmission device 46 can be configured compactly and is suitable for downsizing.
[0039]
The moving device 42 in the embodiment is a lifting device 56 because it moves the table 41 up and down.
The moving device 42 only needs to have a function of changing the distance between the suction device 15 and the sheet-like product 1 to a predetermined value.
Therefore, the table 41 may be fixed and the dispensing unit 13 may be movable.
[0040]
However, when the payout unit 13 is moved, the position of the payout port 24 is changed, so that the table 41 is preferably moved.
Further, the driving device 45 and the transmission device 46 can be integrated.
For example, the moving device 42 may be configured by standing a magnet plate of a linear motor on the side of the side frame 19 and connecting a table to the coil plate.
[0041]
Next, the position sensor 60 will be described.
The position sensor 60 is fixed to a base board 62 that is horizontally disposed between the side frames 19.
The contact 61 of the position sensor 60 is disposed in the upper space of the storage chamber 40, and the lower end thereof is positioned lower than the suction port 20.
When the contact 61 is slightly pushed up by the sheet-like product 1, the position sensor 60 outputs an on signal.
[0042]
At this time, the position of the contact 61 is determined so that the uppermost sheet-like product 1 comes into contact with the suction port 20.
That is, it is determined that the on signal is output at a position where the suction device 15 can perform suction regardless of the posture of the uppermost sheet-like product 1.
Specifically, it is determined that an on signal is output when the uppermost sheet-like product is in close contact with the suction port 20.
[0043]
Therefore, the position sensor 60 is attached so that the position can be adjusted in the vertical direction in FIG.
As the position sensor 60, another type of sensor such as a photoelectric sensor can be used. However, by using a mechanical sensor using the contact 61 as in the embodiment, maintenance such as periodic cleaning is not required and the cost is low.
[0044]
Next, the pre-control device 63 will be described.
In the present embodiment, since the pre-control device 63 is configured by software, first, the control device 70 will be described with reference to FIG.
The control device 70 is, for example, a microprocessor, and the CPU 72 performs predetermined processing while exchanging data with the RAM 73 based on a program stored in the ROM 71. That is, based on the payout instruction signal P, the payout signal F of the payout detection sensor 34, the double picking signal D of the double picking sensor 14, and the upper position signal U of the position sensor 60, the electric motor 21, the second electric motor 32, The operation of the third electric motor 48 is controlled.
[0045]
Next, the operation of the pre-control device 63 will be described based on the flowchart shown in FIG.
In the standby state, the uppermost sheet-like product 1 pushes up the contact 61, and the position sensor 60 is in the on state.
That is, at least a portion in the vicinity of the contact 61 of the uppermost sheet-like product 1 is in close contact with the suction port 20.
Therefore, even if the sheet-like product 1 is in an inclined state, it can be adsorbed by the operation of the suction device 15.
[0046]
In step S1, a dispensing instruction signal P for the vending machine is determined.
If there is a payout instruction signal P, the process proceeds to step S2, and the electric motor 21 of the suction airflow generation device 18 is rotated.
As the electric motor 21 rotates, a fan (not shown) is rotated, and a suction airflow sucked from the suction port 20 is generated.
The uppermost sheet-like product 1 is sucked by the suction airflow and sucked to the suction port 20.
[0047]
In step S3, after measuring a time sufficient for this adsorption, the process proceeds to step S4.
In step S4, the third motor 48 is reversed.
Due to the reverse rotation of the third motor 48, the gear 51 is rotated clockwise in FIG. 3 via the speed reducer 47, the driven gear 50 and the rotating shaft 49.
[0048]
Thereby, since the rack 53 is moved downward, the sheet-like product 1 excluding the sheet-like product 1 sucked by the suction device 15 on the table 41 and the table 41 is also lowered at a slow speed.
By this downward movement, the sheet-like product 1 adsorbed by the suction device 15 and the uppermost sheet-like product 1 on the table 41 are separated from each other by a predetermined distance.
[0049]
Further, since the table 41 moves at a slow speed, no adhesive force due to negative pressure is generated between the adsorbed sheet-like product 1.
Therefore, the lower sheet-like product 1 that has been in close contact with the adsorbed sheet-like product 1 moves downward as the table 41 descends, and only the adsorbed sheet-like product 1 is continuously adsorbed by the suction device 15. .
[0050]
The predetermined distance is a value at which the uppermost sheet-like product 1 of the table 41 is not sucked after the sheet-like product 1 sucked by the suction device 15 is sent out.
After a time sufficient for this separation in Step S5, the rotation of the third motor 48 is stopped in Step S6.
Thereby, the separated state between the adsorbed sheet-like product 1 and the uppermost sheet-like product 1 on the table 41 is maintained.
[0051]
Next, in step S7, the second electric motor 32 of the transport device 16 is rotated.
The rotation of the second electric motor 32 causes the roller 26 of the first transport device 22 and the second roller 28 of the second transport device 23 to rotate counterclockwise in FIG. Is rotated to.
The adsorbed sheet-like product 1 overcomes the frictional resistance with the suction port 20 by frictional contact with the roller 26 and is sent to the second transport device 23.
[0052]
The fed sheet-like product 1 enters between the second roller 28 and the third roller 29 of the second transport device 23 and is conveyed to the payout port 24 by the second roller 28.
When the sheet-like product 1 is positioned between the second roller 28 and the third roller 29, the third roller 29 is moved downward depending on the thickness of the sheet-like product 1.
That is, the lever 31 is rotated clockwise in FIG.
[0053]
When the sheet-like product 1 is one sheet, the rotation amount of the lever 31 is within a predetermined amount, and when two sheet-like products 1 overlap each other, the lever 31 is rotated by a predetermined amount or more.
Accordingly, when the rotation of the lever 31 more than a predetermined amount is detected, since the two sheets are ejected, the two-sheet ejection signal D is output.
The control device 70 outputs a payout stop signal S and an alarm signal A based on this abnormal signal.
By these signals, the automatic dispensing device 10 is stopped and an alarm is issued.
[0054]
Further, since the sheet-like product 1 pushes up the contact 35 when passing through the second transport device 23, the payout sensor 34 outputs a payout signal F.
When the sheet-like product 1 passes through the second transport device 23, the contact 35 moves downward, and the dispensing sensor 34 outputs an off signal.
When the off signal is determined in step S8, the process proceeds to step S9.
[0055]
In step S9, the motor 21 and the second motor 32 are stopped.
That is, the suction flow generation device 18 stops and the suction function of the suction device 15 stops.
Further, the rotation of the first roller 26 and the second roller 28 is stopped.
In other words, the transport function of the transport device 16 is stopped.
Even if the suction function of the suction device 15 remains due to the inertial rotation of the motor 21, the uppermost sheet-like product 1 on the table 41 is sufficiently separated from the suction device 15, so that it is not attracted.
That is, the sheet-like product is not sent out by extra inertia rotation.
Next, in step S10, the third motor 48 is rotated forward.
[0056]
By this forward rotation, the gear 51 is rotated counterclockwise in FIG. 3, so that the rack 53 is moved upward, and as a result, the table 41 is moved upward.
Due to the upward movement of the table 41, the sheet-like product 1 is raised, the contact 61 is pushed up, the position sensor 60 is turned on, and the upper position signal U is output.
If the upper position signal U is determined in step S11, the process proceeds to step S12, and the third motor 48 is stopped.
As a result, the table 41, and thus at least the portion near the contact 61 of the uppermost sheet-like product 1, comes into contact with the suction port 20 and becomes a standby position where the suction device 15 can be sucked.
[0057]
As is clear from the above description, steps S4 to S6 are the pre-control device 63.
That is, the pre-control device 63 has a function of separating the sheet-like product 1 from the suction device 15 after the sheet-like product 1 is sucked by the suction device 15.
Since the pre-control device 63 is configured by software, new parts do not increase, so that it is inexpensive.
Further, the pre-control device 63 constitutes a position adjusting device together with the table 41 and the moving device.
[0058]
In the above description, the terms “upper” and “left” and “left” are used for the convenience of explanation.
Therefore, the apparatus of the embodiment can be used on its side.
