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 particularly, to a dispensing device for feeding a sheet-like product accommodating the card-shaped item into a sheet shaped bag formed by a thin film one by one.
More specifically, the present invention relates to a payout device for sending out a sheet-like product with 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 made of resin, aluminum foil, paper, or the like and has 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. 6,311,867 and Japanese Patent Application Laid-Open No. 2001-118137 in order to pay out the stacked card-like products without damage. The outline will be described below.
After the uppermost stacked sheet-like product is adsorbed by the suction device, it is sent out by the conveying device in contact by the adsorption.
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, and the distance between the uppermost sheet-like product and the suction device is made constant.
[0004]
As described above, 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 moved by the suction device and the conveying device that are operated by inertia. This is to prevent the product from being sent out.
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, the air in the sheet-like product 1 in which the card 1C is sealed in the sheet-like bag 1B formed of the thin film shown in FIG. 7 expands or contracts depending on the ambient temperature.
In order to avoid the influence of the expansion or contraction of the internal air, a plurality of vent holes are perforated in the sheet-like bag 1B.
However, some sheet-like products have insufficient functions of the vents.
A sheet-like product with poor ventilation has an increased thickness when the ambient temperature rises, and the air inside expands.
[0006]
With this increase in thickness, the uppermost sheet-like product is pushed up, and the distance from the suction device becomes closer than the appropriate value.
When the payout signal is received in this state, the uppermost sheet-like product is paid out as described above.
[0007]
However, since the sheet-shaped product that is the topmost is pushed up by the sheet-shaped product having the increased thickness, the distance between the top-level sheet-shaped product and the suction device becomes closer than the appropriate value.
For this reason, the uppermost sheet-like product may be adsorbed by the suction device that is inertially operated and may be paid out partway by the carrier device that is inertially operated.
[0008]
Even when the suction device does not attract the uppermost sheet-like product, the uppermost sheet-like product may come into contact with the transport device and be paid out halfway by the transport device that is inertially operated.
When the sheet-like product is paid out partway, it is detected by a sensor, the vending function is stopped as an abnormal state, and the operating rate of the vending machine is lowered.
This phenomenon may also occur when the expansion rate of the card itself is large.
[0009]
Furthermore, the sheet-like product 1 has a pillow shape in which the central portion is swollen as a whole because air remains in the interior of the sheet-like product 1 or the joint of the sheet exists in the central portion. Therefore, when a large number of the sheet-like products 1 are stacked, the uppermost sheet-like product 1 is necessarily inclined in the longitudinal direction or the width direction.
[0010]
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 as described above.
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, and as a result, is not paid out.
[0011]
Further, when the sheet-like product 1 is adsorbed by the suction device, the sheet-like product 1 is rapidly sucked up, so that an adhesive force is generated due to the negative pressure generated between the sheet-like product 1 and 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.
Furthermore, in order to solve these problems, it is conceivable to add a prevention device, but this increases the cost and is difficult to employ.
[0012]
[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 taken out.
A third object of the present invention is to provide a sheet dispensing apparatus at a low cost.
[0013]
[Means for Solving the Problems]
In order to achieve this object, the present invention provides a table for supporting sheet-like products arranged in a line, a suction device for the sheet-like product, a transport device for the sheet-like product adsorbed by the suction device, and the table. The distance between the sheet-like product and the suction device is changed based on the transfer instruction signal of the sheet-like product and then returned to a predetermined interval, and then the suction device After the operation, an automatic sheet dispensing device is configured by a sheet position control device that separates the suction device and the table by a predetermined distance or more.
[0014]
In this configuration, the sheet-like product is paid out by the transport device while being sucked by the suction device.
Prior to the delivery of a new sheet-like product based on the delivery instruction signal , the sheet position control device releases the distance between the sheet-like product and the suction device to a predetermined value or more and then sets the predetermined value suitable for the delivery. Returned.
[0015]
In other words, when the temperature rises and the sheet-like product swells and the distance between the sheet-like product to be dispensed and the suction device becomes short, the distance between the sheet-like product and the suction device is predetermined prior to the suction of the suction device. After being released above the value, it is restored to a predetermined value that is optimal for payout.
[0016]
Next, the suction device is activated, and the endmost 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.
[0017]
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.
[0018]
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.
[0019]
The present invention provides the suction device and the transport device that are fixed to one side of the storage unit that stores the sheet-like product, and the moving device that moves the table located on the other side of the storage unit to the suction device side. It is preferable to comprise.
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.
[0020]
In the present invention, it is preferable that the moving device includes an electric motor and a rotation direction control device that rotates the electric motor in one direction and then rotates the electric motor 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 the 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.
[0021]
The present invention relates to a table on which a sheet-like product can be placed and movable in the vertical direction, a suction device that is located above the table and sucks the sheet-like product, and a sheet-like product sucked by the suction device in the suction direction. In contrast, it is preferable to include a transporting device that transports in the lateral direction, and a sheet position control device that returns the distance between the table and the suction device to a predetermined distance after being separated based on the payout signal.
[0022]
In this configuration, the distance between the sheet-like product and the suction device is controlled by moving the table.
Based on the payout instruction signal , the table is first moved away from the suction device.
Thereafter, the table is moved in a direction approaching the suction device and brought close to a predetermined distance.
[0023]
Then, the sheet-like product is adsorbed by the suction device, and is shifted out in the lateral direction by the transport device and is dispensed.
Accordingly, since the position of the sheet-like product can be controlled by moving the table, the structure is simple, the size can be reduced, and the cost is low.
[0024]
In the present invention, it is preferable that the sheet position control device includes a position sensor that detects a rising position of the sheet-like product on the table.
When the raised position of the sheet-like product raised by the table is detected by the position sensor, the raising of the table is stopped.
Since the position of the uppermost sheet-like product is controlled based on the output of the position sensor, the stop position becomes the same every time, and the distance between the uppermost sheet-like product and the suction device becomes the same every time.
As a result, the sheet-like product is sucked and paid out every time.
[0025]

[0026]
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.
[0027]
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 a suction port 20.
[0028]
The suction airflow generation device 18 generates an airflow sucked from the suction port 20.
The suction airflow generation device 18 includes a first electric motor 21 having a fan fixed to the output shaft.
The first electric motor 21 is fixed to the upper end portion of the guide tube 17.
When the first electric 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.
[0029]
Next, the transport device 16 will be described.
The transport device 16 has a function of transporting the sheet-like product 1 sucked by the suction device 15 in the lateral 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.
[0030]
The peripheral surface of the first transport device 22 protrudes 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.
[0031]
The first roller 26 has a peripheral surface covered with rubber in order to reduce slippage with the sheet-like product 1.
The 1st conveying apparatus 22 can replace with a roller and can use the belt which moves to the 2nd conveying apparatus 23 direction.
[0032]
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.
[0033]
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 supported rotatably on a fixed shaft 30 fixed to the side frame 19.
The lever 31 is normally rotated counterclockwise 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.
[0034]
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 moves counterclockwise in FIG.
The second transport device 23 may transport the sheet-like product 1 between a pair of belts.
A payout detection sensor 34 is attached to the side of the second roller 28, and its contact 35 is positioned in the movement path of the sheet-like product 1.
[0035]
The double-sheet detection device 14 outputs a double-sheet output signal when the lever 31 is at a predetermined position.
That is, when two sheet-like products 1 are sandwiched between the second roller 28 and the third roller 29 at a time, a sensor (not shown) detects that the lever 31 is rotated more clockwise than usual. Then, a two-sheet output signal is output.
[0036]
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 has traveled 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.
[0037]
Next, the storage unit 12 for the sheet-like product 1 will be described.
As shown in FIG. 2, the storage unit 12 includes a storage chamber 40 that extends in the vertical direction, a table 41 that moves 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.
[0038]
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 moving the sheet-like product 1.
Therefore, if it has this function, another mechanism can be adopted.
[0039]
Next, the moving device 42 will be described with reference to FIG.
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. The drive device 45 is fixed to the speed reducer 47. 3 an electric motor 48, a drive gear (not shown) fixed to the output shaft of the speed reducer 47, a rotary shaft 49 rotatably supported on the side frame 19, a fixed to the rotary shaft 49, and A driven gear 50 that meshes with the drive gear, and a gear 51 that is fixed to the left and right ends protruding from the side frame 19 of the rotating shaft 49 (the right gear is not shown).
[0040]
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.
[0041]
Next, the transmission device 46 will be described with reference to FIGS.
The transmission device 46 having the same structure is disposed 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 pivotally attached by a pin 54 to a stay 52 that protrudes laterally from the table 41.
[0042]
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 that protrudes 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.
[0043]
The moving device 42 in the embodiment is a lifting device 57 because it moves the table 41 up and down.
The moving device 42 only needs to have a function of changing the suction device 15 and the sheet-like product 1 to a predetermined distance.
Therefore, the table 41 may be fixed and the dispensing unit 13 may be moved.
[0044]
However, when the payout unit 13 is moved, the position of the payout outlet 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.
[0045]
Next, the position sensor 60 will be described with reference to FIG.
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 its lower end 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.
[0046]
At this time, the position of the contact 61 is determined such that there is a predetermined interval between the uppermost sheet-like product 1 and the suction port 20.
That is, even when the uppermost sheet-like product 1 is inclined, it is surely adsorbed by the suction of the suction device 15.
Preferably, the position sensor 60 is set to output an ON signal in a state where the uppermost sheet-like product 1 is in contact with the entire circumference of the outer peripheral edge of the suction port 20.
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, a sensor of another type 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 regular cleaning is not required and the cost is further reduced.
[0047]
Next, the sheet position control device 63 will be described.
In the present embodiment, the seat position control device 63 is configured by software. First, the control device will be described with reference to FIG.
The main control circuit 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 detection device 14, and the upper position signal U of the position sensor 60, the first electric motor 21, the second electric motor The operation of the motor 32 and the third electric motor 48 is controlled.
[0048]
Next, the operation of the seat position control device 63 will be described based on the flowcharts shown in FIGS.
In step S1, the dispensing instruction signal P of the control device of the vending machine is determined. If there is a payout instruction signal P, the process proceeds to step S2, and the third electric motor 48 of the moving device 42 is reversed.
The rotation of the third electric motor 48 causes the gear 51 to rotate clockwise in FIG. 3 via the speed reducer 47, the driven gear 50 and the rotating shaft 49.
[0049]
Thereby, since the rack 53 is moved downward, the table 41 and the sheet-like product 1 on the table 41 are moved downward.
Due to the downward movement, the contact 61 pushed up by the sheet-like product 1 moves downward, and the position sensor 60 outputs an OFF signal OFF.
If it is determined in step S3 that the OFF signal is OFF, the process proceeds to step S4, where the third electric motor 48 stops and then rotates forward.
In other words, based on the dispense instruction signal P of the sheet-like items 1 to separate the distance between the sheet-like product 1 and the suction device 15.
[0050]
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.
The upward movement of the table 41 raises the sheet-like product 1, pushes up the contact 61, turns on the position sensor 60, and outputs an upper position signal U.
If the upper position signal U is determined in step S5, the process proceeds to step S6 and the third electric motor 48 is stopped.
As a result, the table 41, and therefore the uppermost sheet-like product 1, comes into contact with at least a part of the peripheral edge forming the suction port 20, and is surely attracted by the suction airflow.
In other words, the uppermost sheet-like product 1 and the suction device 15 are returned to a predetermined interval.
[0051]
In step S7, the first electric motor 21 of the suction airflow generation device 18 is rotated.
A fan (not shown) is rotated by the rotation of the first electric motor 21 and a suction airflow sucked from the suction port 20 is generated.
By this suction airflow, the uppermost sheet-like product 1 is sucked up by the suction airflow and adsorbed to the suction port 20.
In other words, the suction device 15 is operated, and the uppermost sheet-like product 1 is adsorbed by the suction device 15 .
[ 0 052]
In step S8, after measuring a time sufficient for this adsorption, the process proceeds to step S9.
In step S9, the third electric motor 48 is reversed.
The reverse rotation of the third motor 48 causes the gear 51 to rotate clockwise in FIG. 3 via the speed reducer 47, the driven gear 50, and the rotating shaft 49.
[0053]
Thereby, since the rack 53 is moved downward, the sheet-like product 1 excluding the table 41 and the sheet-like product 1 sucked by the suction device 15 on the table 41 is 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.
In other words, the suction device 15 and the table 41 are separated by a predetermined distance or more.
[0054]
Moreover, since the movement of the table 41 is 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. .
[0055]
The predetermined distance is a distance 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 S10, the rotation of the third motor 48 is stopped in Step S11.
Thereby, the separation state between the adsorbed sheet-like product 1 and the uppermost sheet-like product 1 on the table 41 is maintained.
[0056]
Next, in step S12, 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 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.
[0057]
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 moves downward depending on the thickness of the sheet-like product 1.
That is, the lever 31 is rotated clockwise in FIG.
[0058]
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.
Therefore, when the rotation of the lever 31 more than a predetermined amount is detected, the double-sheet output signal D is output because two sheets are output.
The main control circuit 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.
[0059]
Furthermore, since the sheet-like product 1 pushes up the contact 35 when passing through the second transport device 23, the payout detection 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 payout detection sensor 34 outputs an OFF signal.
When the OFF signal is determined in step S13, the process proceeds to step S14.
In step S14, the first electric motor 21 and the second electric 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.
[0060]
Next, in step S15, it is determined whether the position sensor 60 is an OFF signal.
That is, it is determined whether the uppermost sheet-like product 1 is pushing up the contact 61. If the position sensor 60 is outputting the upper position signal U, the process proceeds to step S16 and the third motor 48 is reversed.
[0061]
As a result, the table 41 is lowered through the rack 53 as described above.
That is, after the topmost sheet-like product 1 is paid out, when the next topmost sheet-like product 1 pushes up the contact 61, the topmost sheet-like product 1 is moved by the inertial operation of the suction device 15. There is a risk of being adsorbed and transported to the dispensing outlet 24 by the inertial movement of the transporting device 16.
Table 41, therefore, by lowering the sheet-like product 1 as described above, the sheet-like instruments 1 are prevented from being attracted by the suction device 15, to avoid unnecessary payout.
[0062]
Next, in step S17, the third motor 48 is rotated forward and the table 41 is raised.
Next, the process proceeds to step S18, and when the upper position signal U from the position sensor 60 by the uppermost sheet-like product 1 pushing up the contact 61 is determined, the process proceeds to step S19.
In step S19, the third motor 48 is stopped, and the uppermost sheet-like product 1 is kept at an optimum interval with respect to the suction device 15 and waits for the next payout instruction signal P.
[0063]
As is clear from the above description, steps S2 to S11 are the sheet position control device 63.
Steps S2, S4, and S9 are rotation direction switching means.
That is, the sheet position control device 63 separates the interval between the sheet-like product 1 and the suction device 15 and then approaches again so that the interval between the sheet-like product 1 and the suction device 15 becomes a predetermined interval. After the uppermost sheet-like product is sucked by the device 15, the sheet-like product 1 is separated from the suction device 15 again.
Since the seat position control device 63 is configured by software, new parts do not increase, so that the cost is low.
