The suction airflow generation device 144 is provided in communication with the suction airflow generation device 144.

The first suction port 138A and the second suction port 138B are juxtaposed adjacent to each other in the conveyance direction D of the flat article G.
First suction port 138A and the second suction port 138B is relative to the downstream side of approximately half the length of the conveying direction D of the flat article G are stacked pending savings engaging portion 106.
Specifically, the second suction port 138B includes a rectangular first opening 138B1 and a second opening 138B2 arranged in parallel on a line perpendicular to the transport direction D.
The first opening 138B1 and the second opening 138B2 can be integrally formed.

When the first leveling chamber 140A has a predetermined volume, even if the suction force fluctuates with time, the volume becomes a cushion, and the flat article G falls due to a sudden drop in the suction force. It has the advantage that can be prevented.

Second leveling chamber 140B is a cubic having front wall 148A of the suction body 1 38, the right wall 148B, a predetermined volume enclosed by the first septal wall 146A and the left wall 148C of suction body 1 38

The suction airflow generation device 144 side ends of the first conduction path 142A and the second conduction path 142B are formed in the vertical wall 146V, and the entire opening thereof faces the suction airflow generation device 144.
In other words, the height of the first conduction path 142A and the second conductive path 142B is the approximately one third of the suction air flow generating device 144, vertical standing portion 132V is phase against the entire surface of the suction air flow generating device 144 Therefore, the entire suction action of the suction airflow generation device 144 reaches the first conduction path 142A and the second conduction path 142B.
The vertical wall 146V is adjacent to the suction body 138.
In other words, half of the suction airflow generation device 144 is opposed to the first conduction path 142A, and the other half is opposed to the second conduction path 142B.
Specifically, in FIG. 7, the suction action of the lower half of the suction airflow generation device 144 extends only to the first suction port 138A via the first conduction path 142A, and the suction action of the upper half passes through the second conduction path 142B. Through the second suction port 138B.
In other words, when the flat article G is transported in the transport direction D and the rear end thereof deviates from the first suction port 138A, half suction force of the suction airflow generation device 144 acts on the second suction port 138B. There is an advantage that the flat article G can be continuously adsorbed to the second suction port 138B.
The upper surfaces of the second leveling chamber 140B, the first leveling chamber 140A, the first conduction path 142A, and the second conduction path 142B are closed by a plate-shaped upper wall 139.
A cover 150 of the suction body 138 is covered with a small gap from the upper wall 139.

Next, the suction airflow generation device 144 will be described with reference to FIG.
The suction airflow generation device 144 sucks air from the first suction port 138A and the second suction port 138B through the first conduction path 142A, the second conduction path 142B, the first equalization chamber 140A, and the second equalization chamber 140B. Has the function of
The suction airflow generation device 144 is an electric axial flow fan 152, for example.
Fan 153 is rotated by a first electric motor 154 for rotation about a generally horizontal axis of rotation.
The fan 153 is disposed in the circular hole 158 of the casing 156, and the rotation axis thereof is opposed to the end surface of the vertical wall 146V.

Due to the rotation of the electric axial flow fan 152, negative pressure is generated in the first conduction path 142A and the first equalization chamber 140A, and from the first suction port 138A, to the second conduction path 142B and the second equalization chamber 140B. Negative pressure is generated, air is sucked from the second suction port 138B, and an upward air flow toward the first suction port 138A and the second suction port 138B is generated.
The suction airflow generation device 144 can employ a method of generating a suction airflow by the ejector effect.
Further, the suction airflow generation device 144 can rotate the electric axial flow fan 152 by an air motor .

When the electric axial flow fan 152 is operated, a suction action that occurs in a half of the suction area with the vertical line as a boundary acts on the first conduction path 142A.
Since the first conduction path 142A is substantially straight, there is almost no flow path loss, and the suction action reaches the first equalizing chamber 140A.
Since the area of the first suction port 138A is small with respect to the volume of the first leveling chamber 140A, a uniform negative pressure is generated in the entire area of the first suction port 138A.
The suction action that occurs in the other half of the electric axial fan 152 acts on the second conduction path 142B.
Since the second conduction path 142B extends substantially in a straight line and then reaches the second leveling chamber 140B having a right angle, the suction action receiving the flow path loss at the right-angled portion reaches the second leveling chamber 140B.
Since the area of the second suction port 138B is small with respect to the volume of the second leveling chamber 140B, a uniform negative pressure is generated over the entire area of the second suction port 138B ( the first opening 138B1 and the second opening 138B2).
Accordingly, approximately half of the front side of the flat article G in the traveling direction is adsorbed by the first suction port 138A and the second suction port 138B.

When the flat article G is conveyed in the conveyance direction D and the surface line where the first suction port 138A is covered by the flat article G becomes smaller, the suction force at the first suction port 138A decreases rapidly.
However, since the entire surface of the second suction port 138B is covered with the flat article G, one half of the suction action of the electric axial fan 152 acts as an adsorption force.
While this one-half adsorption force is acting on the flat article G, the tip of the flat article G is sandwiched between first clamping and conveying devices 194 described later.
Thereby, even if the suction force of the second suction port 138B is reduced, the flat article G is reliably sent out.

By securing the suction airflow from the first suction port 138A and the second suction port 138B, overheating due to overload of the first electric motor 154 is prevented, and friction between the flat article G and the lower wall 137 of the suction body 138 is prevented. The contact is reduced and the conveyance resistance of the flat article G is minimized.
However, when the conveyance interval of the flat article G is large, the lower wall 137 and the flat article G may be brought into contact with each other.
The first roller 174, the second roller 178, and the third roller 180 have their peripheral surfaces covered with rubber in order to reduce slippage with the flat article G.
Further, in order to increase the frictional force with the flat article G, the first roller 174 has convex portions 182 formed at appropriate intervals.

Next, the control by the control device 380 will be described with reference to the flowcharts shown in FIGS.
Prior to operation, the lid 126 is opened and the flat article G is stored in the storage chamber 290.
In other words, when the movable table 292 is not at the lowest position, the movable table 292 is pushed down to a position where the operator cannot push it down to form a storage space for the flat article G.
When the lid 126 is tilted by a predetermined angle, the cam 340 pushes the cam follower 345 to move the rod 339 from the position of FIG. 11 to the position of FIG.
As a result, the bracket 323 is rotated clockwise as shown in FIG. 12, and the meshing between the drive gear 332 and the driven gear 334 is released.
As a result, the movable table 292 receives the resistance of the flexible rack 352, the rotating shaft 342, the pinion gears 344A, 344B, and the like, but can move downward, so that the movable table 292 is manually pushed down to the lowest position.
In this state, since the action piece 348 is separated from the sensor 347, the projection light is not blocked, and the sensor 347 cannot output the closing signal CS.
After the movable table 292 is pushed down, the flat article G is stacked on the movable table 292 by a predetermined amount, and then the lid 126 is closed.
As a result, the action piece 348 blocks the projection light, so that the sensor 347 can output the closing signal CS.

When the control device 380 is turned on, initial setting is performed.
First, in step S1, it is determined whether the sensor 347 outputs the closing signal CS.
If the lid 126 as described above is closed the front side opening 122, the sensor 347 goes to step S2 so that outputs a closing signal CS.
If closed port signal CS is not output, the process proceeds to step S3, looping through step S1 outputs the opening error signal of the lid 126.
When the operator closes the lid 126 properly, the sensor 347 outputs the closing signal CS, and the process proceeds to step S2.
First sensing device 2 04A it is determined whether the outputs ready position signal US in step S2.
If you do not determine the ready position signal US, the process proceeds to step S3, the third electric motor 3 26 after having been rotated forward, the process returns to step S2.
As a result, the pinion gears 344A and 344B are rotated forward, the flexible rack 352 is moved upward, and the movable table 292 is raised via the connecting device 358.
As the movable table 292 rises, the uppermost flat article G pushes up the contact piece 206A of the first detection device 204A, so that the first detection device 204A outputs the preparation position signal US.
When the preparation position signal US is determined in step S2, the process proceeds to step S4.
In step S4, it stops the third electric motor 3 26 proceeds to step S5.
In step S5, the payout instruction signal P of the control device of the vending machine is determined.
If dispense instruction signal P is present, the process proceeds to step S6, the third electric motor 326 of the mobile device 29 7 is reversed.
Rotation of the third electric motor 3 26, the pinion gear 344A via reduction gear 324, etc., 344B is rotated in the counterclockwise direction in FIG. 1.

As a result, the flexible rack 352 is moved downward to move the movable table 292 and the flat article G on the movable table 292 downward.
By this downward movement, the contact piece 206A pushed up by the flat article G moves downward, and the first detection device 204A stops outputting the preparation position signal US.
If it is determined in step S7 that this preparation position signal US does not exist, the process proceeds to step S8.

In step S8, after the third electric motor 3 26 which is stopped, it is forward.
Due to this forward rotation, the pinion gear 344B is rotated clockwise in FIG. 1, so that the flexible rack 352 moves upward, and as a result, the movable table 292 moves upward.
By the upward movement of the movable table 292, the flat article G rises, pushes up the first contact piece 206A, and the first detection device 204A outputs the preparation position signal US.

In step S9, when determining the ready position signal US, the process proceeds to step S10, the third electric motor 3 26 is stopped.
Thus the movable table 292, therefore, the flat article G topmost is at least the second roller 1 78 and the third roller 1 80 located in the first roller 174 and the second suction port 138B is located at the first suction port 138A Located slightly below the bottom surface.
In other words, the uppermost flat article G is positioned at a position that is surely adsorbed by the suction airflow, facing the entire surface of the first suction port 138A and the second suction port 138B.

In step S11, the first electric motor 154 of the suction device 132 is rotated.
The electric axial flow fan 152 is rotated by the rotation of the first electric motor 154, and the first suction passage 142A, the second conduction passage 142B, the first equalizing chamber 140A, and the second equalizing chamber 140B are first suctioned, respectively. A suction air flow is generated from the port 138A and the second suction port 138B.
By this suction airflow, the uppermost flat article G is sucked up and adsorbed by the first suction port 138A and the second suction port 138B.

In other words, the upper surface of the uppermost flat article G contacts the lower surfaces of the first roller 174, the second roller 178, and the third roller 180.
In this state, since there is a slight gap between the upper surface of the flat article G and the first suction port 138A and the second suction port 138B, predetermined suction to the flat article G is performed by sucking air from the gap. While maintaining the force, the air current is applied to the first electric motor 154 to cool it.

In step S12, after measuring a time sufficient for this adsorption, the process proceeds to step S12.
In step S13, the third electric motor 3 26 is reversed.
The reverse rotation of the third electric motor 3 26, the pinion gear 344A, 344B is rotated in the counterclockwise direction in FIG. 1.
As a result, the flexible rack 352 is moved downward, so that the flat articles G on the movable table 292 and the movable table 292 excluding the flat articles G adsorbed by the first suction port 138A and the second suction port 138B are loosened. Decrease at speed.
By this downward movement, the flat article G adsorbed by the first suction port 138A and the second suction port 138B is separated from the uppermost flat article G on the movable table 292 by a predetermined distance.

Since the movement of the movable table 292 is slow, no adhesive force due to negative pressure is generated between the adsorbed flat article G and the flat article G below it.
Therefore, the lower flat article G that is in close contact with the adsorbed flat article G moves downward as the movable table 292 is lowered, and only the adsorbed flat article G is the first suction port 138A and the second suction port 138B. Is continuously adsorbed.

The predetermined distance is a distance at which the flat article G on the movable table 292 is not sucked by the first suction port 138A and the second suction port 138B even when the suction flat article G is transported in the transport direction D.
After sufficient time has been timed in step S14 in this separation, the process proceeds to step S15.
In step S15, the process proceeds to step S16 after the rotation of the third electric motor 3 26 is stopped.
As a result, the separated state between the adsorbed flat article G and the uppermost flat article G on the movable table 292 is maintained.

Next, in step S16, the second electric motor 223 of the first lateral conveyance device 134 is rotated.
Due to the rotation of the second electric motor 223, the first roller 174, the second roller 178, the third roller 180, and the second transmission gear train 236 of the first lateral conveying device 134 are passed through the first transmission gear train 234. Thus, the rollers 200A and 200B of the second lateral conveying device 136 are rotated clockwise in FIG.
The adsorbed flat article G is moved in the left lateral conveyance direction D in FIG. 6 by frictional contact with the first roller 174, the second roller 178, and the third roller 180, and is directed to the second conveyance device 188. Sent.

The sent flat article G is sandwiched between the upper roller device 198 and the lower roller device 202 of the first nipping and conveying device 194 of the second conveying device 188 and moved in the same direction. It is sandwiched between rollers and conveyed to the payout opening 130.
In this process, the flat article G gradually decreases in relative area with the first suction port 138A.
In other words, the opening area of the first suction port 138A gradually increases, and the adsorption force with respect to the flat article G rapidly decreases.

However, since the entire surface of the second suction port 138B is opposed to the flat article G, the flat article G is continuously adsorbed to the second suction port 138B.
Accordingly, the flat article G is conveyed in the lateral direction while maintaining its horizontal posture.
When the front end of the flat article G reaches just before the second nipping and conveying device 196, the rear part of the flat article G starts to come off from the second suction port 138B, and the adsorption force to the flat article G decreases rapidly.

However, since the flat article G is held by the first holding / conveying device 194, the horizontal conveyance is continued.
In other words, even when the rear end portion of the flat article G is detached from the second suction port 138B, the flat article G is sandwiched between the upper roller device 198 and the lower roller device 202 of the first holding and conveying device 194. Is kept almost horizontal and continues to be transported in the horizontal direction.
And it is pinched | interposed into the 2nd clamping conveyance apparatus 196, and is further conveyed to a horizontal direction.
In this process, the tip of the flat article G passes through the shutter 216 by turning it counterclockwise.

Flat article G Since pushes up the contact Sawahen 206B as it passes through the first clamping and conveying device 194, the second sensing device 204B outputs a detection signal DS1.
When the trailing edge of the flat article G passes through the first clamping and conveying device 194, contact Sawahen 206B is moved downward, the second sensing device 204B will not output a detection signal DS1.
When it is determined in step S17 that the detection signal DS1 is not output, the process proceeds to step S18.
In step S18, the first electric motor 154 and the second electric motor 223 are stopped.
That is, the suction device 132 is stopped and the suction function of the suction device 132 is stopped.
Also, the first lateral transport device 134 and the second lateral transport device 136 are stopped.

Next, in step S19, it is determined whether or not the first detection device 204A outputs the preparation position signal US.
That is, it is determined whether the uppermost flat article G pushes up the first contact piece 206A.
If the first detector 204A outputs the preparation position signal US, the process proceeds to step S20, and the third electric motor 326 is reversed.

Thus, the movable table 292 via a full lexical table rack 352 is lowered.
That is, after the flat article G topmost is paid out, if the flat article G of the next uppermost pushing up against Sawahen 206A, flat article G topmost is adsorbed by the inertia operation of the suction device 132 In addition, there is a risk of being transported to the payout opening 130 due to the inertial movement of the first lateral transport device 134.
By moving the movable table 292, and thus the flat article G, as described above, the flat article G is prevented from being adsorbed by the suction device 132, and unnecessary payout is avoided.

Next, when the preparation position signal US is not output in step S19, the process proceeds to step S21.
In step S21, it is determined whether the second detection device 204B has stopped outputting the detection signal DS1, and if not, the process proceeds to step S22 to determine whether a predetermined time has elapsed, and if not, the process returns to step S21.
If the signal does not change even after a predetermined time has elapsed, the flat article G jams in the second lateral conveyance device 136, determines that it is in an abnormal state, outputs an abnormal signal in step S25, and then ends the process.

In step S21, when it is determined that the detection signal DS1 of the second detection device 204B is not output after it is output, the process proceeds to step S23.
In step S23, it is determined whether or not the detection signal DS2 of the third detection device 204C is not output after being output.
If it is not determined that there is no detection signal DS2, the process proceeds to step S24 to determine whether a predetermined time has elapsed, and if not, the process returns to step S23.
If the signal does not change even after a predetermined time has elapsed, it is determined that the flat article G has jammed in the second lateral conveyance device 136, the process proceeds to step S25, an abnormal signal is output, and the process is terminated.

If it is determined in step S23 that the signal has changed, the process proceeds to step S26.
In step S26, after the third electric motor 3 26 it is forward, the movable table 292 is raised, the process proceeds to step S27.

  In step S27, when the preparation position signal US from the first detection device 204A due to the uppermost flat article G pushing up the first contact piece 206A is determined, the process proceeds to step S28, and if not, step S27 is looped.

In step S28, the third electric motor 226 is stopped and the process is terminated.
As a result, the uppermost flat article G is secured at an optimum interval with respect to the first suction port 138A and the second suction port 138B, and waits for the next payout instruction signal P.

In the present embodiment, the electric axial fan 152 may be rotated about the vertical axis.
Furthermore, the exhaust flow of the electric axial flow fan 152 can be blown between the flat article G to be adsorbed and the flat article G below it to be used as a separated airflow.
