Further, as described above, since the upper arm 52 and the lower arm 53 are in a positional relationship facing each other, when the upper arm 52 rotates, the lower arm 53 opens and closes each other.

A power output gear (power output member) 36 is mounted on the lower arm 53 so as to freely rotate. The center axis 66 of the power output gear 36 is eccentric to the gear 62 fixed to the lower arm 53 as shown in FIG. The power output gear 36 is connected to the roller 4 described above.
It is engaged with a gear 46 provided on an extension of zero. When the upper arm 52 rotates as described above, the lower arm 5
3 rotates about a shaft 61, but the power output gear 36, which is mounted so as to freely rotate, is located eccentrically with respect to the shaft 61 of the lower arm 53.
1 is located on an extension of the rotation shaft 65 of the roller 40, so that when the lower arm 53 rotates, the power output gear 36
The gear 4 provided on an extension of the rotation shaft 65 of the roller 40
Orbit around 6. Therefore, even if the lower arm 53 rotates, the power output gear 36 attached to the lower arm 53
Maintain engagement with a gear 46 provided on an extension of the roller 40. Thus, the driving gear 46 and the power output gear 3
6 and the lower arm 53 constitute a kind of operating gear train, the driving gear 46 mechanically functions as a sun gear, and the power output gear 36 functions as a planetary gear. In addition, lower arm 5
Reference numeral 3 functions as an arm member for maintaining a relative positional relationship between the power output member and the drive member.

The product take-out device 6 is attached to the vertical track 21, and the holding device 37 of the product take-out device 6 faces the product placing table 10.

Next, a power circuit and a signal circuit of the vending machine 1 of this embodiment will be described. In the vending machine 1 of the present embodiment, as described above,
The storage battery 30 is provided, and the electric power of the electric motor and the lamp provided at the moving part is entirely covered by the storage battery 30. More specifically, at least the vertical trajectory 2
An electric motor (not shown) for moving 1 horizontally;
A motor (not shown) for raising and lowering the product take-out device 6, a motor 35 for driving the product take-out device 6, a motor 55 for driving the holding device 37, and a motor (not shown) for driving the vacuum pump are Power is supplied from the storage battery 30 as shown in FIGS. The receiver 31 provided at the lower end of the vertical track 21 also receives power from the storage battery 30. Therefore, in the vending machine 1 of the present embodiment, there is no power supply cable connecting the fixed side and the vertical track 21. As described above, the power receiving connector 27 provided on the vertical track 21 is connected to the storage battery 30, and the power receiving connector 27 and the pair of power transmitting connectors 26 are connected to the DC power supply 28.

Further, in the vending machine 1 of the present embodiment, as described above, the receiver 31 is provided at the lower end of the vertical orbit 21, and the control of the members provided at the moving parts is all performed by the receiver. This is performed based on the reception signal of the device 31. That is, the moving position (stop position) of the XY transport device 5 is determined by the reception signal of the receiver 31. Specifically, the information such as the position of the shelf input from the operation panel 8 is converted into a radio wave by the transmitter 68 disposed at the corner of the main body case 2.
It is transmitted by radio waves and received by the receiver 31 attached to the vertical orbit 21. Then, based on this signal, X
-The Y transport device 5 operates. Therefore, in the vending machine 1 of the present embodiment, there is no signal cable connecting the fixed side and the vertical track 21.

Next, the operation of the vending machine 1 of this embodiment will be described. In the vending machine 1, the vertical trajectory 21 of the XY transfer device 5 is always waiting at the leftmost standby position, as shown in FIG. At this time, the power receiving side connector 27 provided near the upper end of the vertical track 21
0, which is in contact with a power transmission side connector 26 provided near the left end, is supplied with power from a DC power supply 28 to a storage battery 30 attached to the vertical track 21, and the storage battery 30 is charged.

When purchasing products from the vending machine 1,
A predetermined amount of money is inserted through the coin insertion slot 7, and a desired product is selected by operating the ten keys of the operation panel 8. Here, in the vending machine 1 of this embodiment, since the main body case 2 is transparent, the user selects a product while viewing the product storage shelf 3 from outside.

The signal of the numeric keypad is sent to a transmitter 68 located at a corner of the main body case 2 and emitted from the transmitter 68 as a radio wave. This signal is received by the receiver 31 placed on the vertical track 21 of the XY transport device 5, and the XY transport device 5 is moved to a predetermined position. At this time, FIG.
As shown in (b), the vertical track 21 moves parallel to the right along the horizontal track 20, and the power receiving connector 27 is separated from the power transmitting connector 26. However, since each of the electric motors is supplied with power from the storage battery 30 placed on the vertical track 21, the XY transport device 5 continues to operate.

Then, the XY transport device 5 stops the product take-out device 6 in front of the product placement table 10 on which the desired product is placed. At this time, the power input gear 16 and the shaft 19 of the product mounting table 10 are connected to the holding device 3 of the product removal device 6.
7. Then, in this state, the electric motor 55 is driven to operate the upper arm 52 and the lower arm 53 of the holding device 37, and the product take-out device 6 is connected to the product mounting table 10. That is, the electric motor 55 is driven by discharging the storage battery 30, and the upper arm 52 of the holding device 37 is rotated in the direction of the arrow in FIGS. The gear 58 fixed to the upper arm 52 rotates with the rotation of the upper arm 52, and further, the gear 62 engaged with the gear 58 rotates. Therefore, the lower arm 53 rotates integrally with the gear 62 in the direction of the arrow in FIGS. As a result, the upper arm 52 and the lower arm 53 of the holding device 37 rotate in a direction to close each other, and FIG.
The upper arm 52 and the lower arm 53 are
The lower shaft 53 and the notch 59 of the lower arm 53.
The shaft 19 is engaged with the horizontal groove portion of. In this embodiment,
The notch 59 of the lower arm 53 has a wide opening, so that the shaft 19 can be smoothly received.

The power output gear 36 attached to the lower arm 53 so as to rotate freely with the rotation of the lower arm 53.
Revolves around the drive gear 46 while still engaged with the drive gear 46, and the power output gear 36 gradually approaches the power input gear 16 on the product mounting table 10, and finally the power output gear 36 on the product mounting table 10 side. It comes into contact with the power input gear 16. Thus, the power output gear 36 provided on the lower arm 53 of the product take-out device 6 is engaged with the power input gear 16 of the product mounting table 10. According to the configuration of the present embodiment, the power output gear 36 provided on the lower arm 53 is placed on the same plane as the power input gear 16 on the product mounting table 10 side, and the distance between the shafts is gradually reduced. Since the engagement state is reached, the teeth of the gears rarely collide during engagement. Therefore, according to the configuration of the present embodiment, the gears are smoothly engaged with each other. In this embodiment, the notch 5 of the lower arm 53 is used.
9, the shaft 19 on the product mounting table 10 side is held, so that the power output gear 36 on the product take-out device 6 side,
The distance of the power input gear 16 on the product mounting table 10 side and the positional relationship in the left-right direction are ideal. Further, the shaft 19 on the product mounting table 10 side is held by the notch portion 59 of the lower arm 53, so that the power output gear 36 and the power input gear 16 are rotated by the force generated when the gear 3 is rotated.
6 and 16 are also prevented from escaping, and reliable power transmission is performed.

The upper arm 52 and the lower arm 53 of the holding device 37 hold the shaft 19 on the product loading table 10 side, and the gear (power output member) 36 on the product loading device 6 side and the product loading table 10 side. When the power input gear 16 is engaged, the rotation of the motor 55 is stopped, and the motor 35 provided below the roller 40 is driven instead. The rotation of the electric motor 35 is reduced by the speed reducer 50, transmitted to the gear 51, and further transmitted to the gear 45 integrated with the roller 40. As a result, the roller 40 rotates, and the conveyor belt 43 on the merchandise take-out device 6 travels in the direction of the arrow in FIG.

On the other hand, as the roller 40 rotates, the roller 4
The drive gear 46 attached to the 0 rotates. As described above, the power output gear 36 of the lower arm 53 maintains a relative positional relationship with the drive gear 46 by the lower arm 53, and the power output gear 36 is always engaged with the drive gear 46, and Since the power output gear 36 of the arm 53 is engaged with the power input gear 16 of the product mounting table 10, the roller 11 of the product mounting table 10 also rotates with the rotation of the roller 40 of the product removal device 6. I do. Here, in the present embodiment, as described above, the notch 59 of the lower arm 53 holds the shaft 19 on the product mounting table 10 side, so that the power output gear 36 on the product removal device 6 side and the product output gear 36 The distance of the power input gear 16 on the mounting table 10 and the positional relationship in the left-right direction are ideal. Further, the shaft 19 on the side of the product mounting table 10 is held by the notch portion 59 of the lower arm 53, so that the power output gear 36 and the power input gear 16 rotate when the gear 36,
Since the escape of the power 16 is also prevented, the engagement between the power output gear 36 on the product take-out device 6 side and the power input gear 16 on the product mounting table 10 is ensured. Therefore, power is transmitted from the power output gear 36 on the product take-out device 6 side, and the power input gear 16 on the product mounting table 10 rotates. Accordingly, the conveyor belt 13 on the product placing table 10 also travels in the direction of the arrow in FIG.

As a result, the products on the product mounting table 10 are delivered by a delivery device (conveyor device) composed of the rollers 11 and 12 and the conveyor belt 13, moved to the product removal device 6, and moved to the product removal device 6. It is taken to 6 side. The running speed of the conveyor belt 43 on the product pick-up device 6 side and the running speed of the conveyor belt 13 on the product mounting table 10 differ depending on the number of gear teeth and the diameter of the roller. Is designed to be faster. Therefore, when a part of the product comes into contact with the conveyor belt 43 on the product take-out device 6 side, the product smoothly passes between the conveyors and moves to the product take-out device 6 side.

In the present embodiment, the number of teeth of each gear is unified, and only the diameters of the rollers 11 and 12 on the product mounting table 10 and the diameters of the rollers 40 and 41 on the product take-out device 6 are different. Rollers 40, 4 on the product take-out device 6 side
1 is designed to be larger than the product mounting table 10 side. As a result, the traveling speed of the conveyor belt 43 on the product take-out device 6 side is faster than that on the product placement table 10 side. By designing in this way, the product take-out device 6
Products on the product mounting table 10 can be reliably taken out one by one. That is, according to the present embodiment, the traveling speed of the conveyor belt 43 on the side of the product take-out device 6 is controlled by the product mounting table 1.
Since the product is faster than the 0 side, when the product reaches the product take-out device 6 side, it is drawn into the conveyor belt 43 of the product take-out device 6 side, and the distance to the following product is widened. Therefore, the detection accuracy of the sensor and the like are improved, and the problem that two or more products are discharged at a time is eliminated.

When it is confirmed by a sensor or the like (not shown) that the product has moved to the product take-out device 6, the motor 35 is stopped and the conveyor device is stopped. Subsequently, the electric motor 55 of the holding device 37 is rotated in the direction opposite to the previous direction, and the upper arm 52 and the lower arm 53 are turned in the opening direction, thereby releasing the holding of the shaft 19 on the product mounting table 10 side. At this time, the lower arm 53
At the same time, the power output gear 36 escapes, and the engagement relationship between the power output gear 36 on the product take-out device 6 side and the power input gear 16 on the product mounting table 10 is released.

Subsequently, the XY transport device 5 is operated, and the product take-out device 6 is moved to a position corresponding to the product take-out port 9. Here, the user is required to take out the product outlet 9
And take out the desired product. When a series of operations is completed, the XY transport device 5 returns to the original standby position. Then, the power receiving side connector 27 provided on the vertical track 21 is joined to the power transmitting side connector 26 again, and the charging of the storage battery 30 is restarted.

(Embodiment 2) Next, a second embodiment of the present invention will be described. The same members as those in the previous embodiment are denoted by the same reference numerals, and duplicate description will be omitted. FIG.
It is explanatory drawing which shows the relationship between the drive part and main body frame of the merchandise removal device of the vending machine of the second embodiment of the present invention. The product take-out device 110 employed in the vending machine of the present embodiment further increases the degree of freedom of the power output gear 36, the holding device 37, and the like, and further ensures the engagement relationship between the power output gear 36 and the power input gear 16. It is intended to be something. That is, in the vending machine according to the second embodiment, the product removal device 110
Has a body frame 112, and a series of power transmission members from the electric motor 35 to the power output gear 36 via the speed reducer 50, the gears 51, 45, and 46, and the holding device 37 can swing with respect to the body frame 112. Installed. More specifically,
The series of power transmission members and the holding device 37 are both attached to a swing lever 113, and the swing lever 113 is swingably fixed to the main body frame 112 by a pin 115 at the other end. The swing lever 113
Is preferably biased toward one side by a spring or the like.

The product take-out device 11 employed in this embodiment
At 0, since the swing lever 113 is swingably fixed to the main body frame 112 by the pin 115, the series of power transmission members and the holding device 37 are free to swing in the swing direction about the pin 115. It can move with a degree. As described in the first embodiment, the upper arm 52 and the lower arm 53 constituting the holding device 37 are movable in the opening and closing directions, and the power output gear 36 is connected to the drive gear 46. It moves in the orbital direction. Therefore, in the vending machine of the second embodiment, the power output gear 36 and the holding device 3
7 has a degree of freedom in the rotation direction about one axis (pin 115) as compared with the previous embodiment. That is, in the present embodiment, the power output gear 36 and the holding device 37 are movable with two degrees of freedom. Therefore, in the product take-out device 110 employed in the present embodiment, even if a slight drop occurs between the product placement table 10 for some reason, the power output gear 36 and the holding device 37 move up and down, and the power output gear 36 and the power input gear 16 return to an ideal positional relationship and engage.

In the present embodiment, the power output gear 36 and the like are attached to the swing lever 113, and this is fixed to the main body frame 112 with the pin 115. In addition, a guide member is provided on the main body frame 112, and the power output gear is provided. The same operation and effect can be expected even if the structure such as 36 can move up and down along the guide.

(Embodiment 3) In the embodiments described above, the holding device 37 is driven by the independent motor 55, but the motor 55 is omitted and the holding member 37 is driven by the motor 35 for running the conveyor belt 43. Can also be driven. Hereinafter, this configuration will be described as a third embodiment. FIG. 12 is a perspective view of a drive unit of a product take-out device of a vending machine according to a third embodiment of the present invention and a connection portion with a product delivery unit on the shelf side. FIG. 13 is a mechanism diagram illustrating a combination mechanism of the gears and the like in FIG. 12. FIG. 14 is an explanatory diagram illustrating the operation of the XY transport device of the vending machine in FIG.

In the merchandise take-out device 120 employed in the vending machine of the present embodiment, unlike the previous embodiment, the electric motor 55
And the upper arm 52 and the gear 58 attached to them. As shown in FIGS. 12 and 13, the rotation shaft 65 of the roller 40 is extended and connected to the lower arm 53. That is, the shafts of the gear 45 and the drive gear 46 are extended and connected to the lower arm 53. Here, in the present embodiment, a torque limiter 121 is interposed between the lower arm 53 and the rotating shaft 65. Torque limiter 121
As shown in FIG. 13B, a substantially disk-shaped inner ring member 122 is provided.
And an outer ring member 123 having a circular concave portion, in which grease having extremely high viscosity is filled. The torque limiter 121 rotates the inner ring member 122 and the outer ring member 123 via grease.
When the load torque between them is less than a certain value, the inner ring member 122 and the outer ring member 123 rotate integrally due to the viscosity of the grease. On the other hand, if the load torque between the two exceeds a certain value, the torque of both cannot be transmitted due to the viscosity of the grease, and the inner ring member 122 and the outer ring member 123 can rotate separately. However, even in this case, when one of them rotates, a certain amount of force is generated on the other member due to the resistance of the grease. Thus, the torque limiter 121 has a property that rotation is transmitted when the load torque is less than a certain torque.

When using the vending machine of this embodiment,
By operating the XY transport device 5 in the same manner as in the previous embodiment, the product take-out device 120 is stopped in front of the product mounting table 10 on which a desired product is mounted. Subsequently, the electric motor 35 provided below the roller 40 is driven. The rotation of the electric motor 35 causes the gear 45 to rotate, and further the roller 40 to rotate.
Drive in the direction of arrow 2. On the other hand, in the vending machine of the present embodiment, the rotation shaft 65 of the roller 40 is extended and connected to the lower arm 53 via the torque limiter 121.

Here, in this embodiment, a torque limiter 121 is interposed between the lower arm 53 and the rotating shaft 65. Immediately after the product removal device 120 stops in front of the product mounting table 10 on which a desired product is mounted, the lower arm 53 does not contact any member. Therefore, immediately after the product removal device 120 stops in front of the product mounting table 10 on which a desired product is mounted, the lower arm 53 is free. It is in a state where free rotation is possible. Therefore, a large torque is not required to rotate the lower arm 53. The torque required to rotate the lower arm 53 at this time is within a range in which the torque limiter 121 can transmit the rotating force. The rotation of the rotating shaft 65 is transmitted to the lower arm 53 via the torque limiter 121, 53 corresponds to FIG.
2, 14 (a). As a result, the shaft 19 engages with the horizontal groove of the cutout 59 of the lower arm 53 of the holding device 37.

With the rotation of the lower arm 53, the power output gear 36 attached to the lower arm 53 so as to rotate freely.
Revolves around the drive gear 46 while still engaged with the drive gear 46, and the power output gear 36 gradually approaches the power input gear 16 on the product mounting table 10, and finally the power output gear 36 on the product mounting table 10 side. It comes into contact with the power input gear 16. Thus, the power output gear 36 provided on the lower arm 53 of the product take-out device 6 is engaged with the power input gear 16 of the product mounting table 10.

When the power output gear 36 engages with the power input gear 16 on the product mounting table 10 in this way, the power input gear 16 cannot revolve any further, and the lower arm 5
3, a large load torque is applied. Here, in this embodiment,
Since the lower arm 53 and the rotating shaft 65 for rotating the lower arm 53 are joined via the torque limiter 121, the torque required for the rotation of the lower arm 53 is reduced when the power output gear 36 is engaged with the power input gear 16. The transmission limit of the torque limiter 121 is exceeded. Therefore, the rotation shaft 65 is relatively rotatable, and the rotation of the rotation shaft 65 is
3 will not be transmitted.

Accordingly, the lower arm 53 stops rotating, and the power output gear 36 and the power input gear 16 maintain the engaged state. The torque limiter 121 does not transmit rotation, but continues to generate force due to the viscosity of grease.
The lower arm 53 is always urged in the direction of the arrow, and the power output gear 36 presses the power input gear 16 with a constant force. Therefore, the power output gear 36 and the power input gear 16
Continue to engage in an ideal state.

When the power output gear 36 and the power input gear 16 are disengaged for some reason, the torque required for the rotation of the lower arm 53 falls below the transmission allowable range of the torque limiter 121, and the lower arm 53 is re-engaged. By rotating, the power output gear 36 and the power input gear 16 are engaged. In other words, the lower arm 53 follows the power output gear 36 until it engages with the power input gear 16 by the action of the torque limiter 121. Then, the power output gear 36 is constantly pressed against the power input gear 16 with a constant force. Then, as in the previous embodiment, when the power input gear 16 on the product mounting table 10 rotates, the conveyor belt 13 on the product mounting table 10 runs, and the product is paid out.

(Embodiment 4) In the embodiment described above, the torque limiter 121 is attached to the shaft portion for rotating the lower arm 53. However, the attachment position of the torque limiter 121 is not limited to the portion. The function of the torque limiter is to move the lower arm 53 as an arm member to the power output gear 3.
6 is rotated until it engages with the power input gear 16, and when both engage, the rotation is stopped. Therefore, torque is transmitted to any of the power transmission paths for rotating the lower arm 53 as an arm member. If the limiter 121 is provided, a desired function is exhibited. The above-described embodiment is an example in which the center of the lower arm 53 is rotated to rotate the lower arm 53,
A torque limiter is provided at the center of rotation of the lower arm 53. On the other hand, it is also possible to rotate the lower arm 53 by applying a force to the peripheral side of the lower arm 53. When this configuration is adopted, torque is applied to a portion other than the rotation center of the lower arm 53. The limiter 121 will be provided. Hereinafter, as a fourth embodiment of the present invention, an example in which a torque limiter 121 is provided at a portion other than the center of rotation of the lower arm 53 will be described.

FIG. 15 is a perspective view of a drive unit of a product pick-up device of a vending machine according to a fourth embodiment of the present invention and a connection portion with a product pay-out unit on the shelf side. FIG. 16 is a mechanism diagram illustrating a combination mechanism of the gears and the like in FIG. 15. FIG.
FIG. 16 is an explanatory diagram illustrating the operation of the XY transport device of the vending machine in FIG. In the product take-out device 130 employed in the vending machine in this embodiment, a torque limiter 121 is interposed between the power output gear 36 and the lower arm 53.
That is, also in the vending machine of the present embodiment, the power output gear 36 is attached to the lower arm 53, but the torque limiter is provided between the central shaft (fixed shaft) 66 provided on the lower arm 53 and the power output gear 36. 121 is interposed.
Here, the central shaft 66 is integral with the lower arm 53. The torque limiter 121 has a property that rotation is transmitted when the load torque is less than a certain torque. Therefore, when the load torque is less than the fixed torque, the power output gear 36 and the central shaft (fixed shaft) 66 are integrated, and the power output gear 36 cannot rotate. On the other hand, when the load torque exceeds a certain value, the power output gear 36 becomes rotatable relative to the center shaft (fixed shaft) 66, and becomes idle. Briefly, in the present embodiment, the power output gear 36 does not rotate below a certain torque.

When using the vending machine of this embodiment,
The XY transport device 5 is operated in the same manner as in the previous embodiment, and the product take-out device 130 is stopped in front of the product mounting table 10 on which a desired product is mounted. Subsequently, the electric motor 35 provided below the roller 40 is driven. The rotation of the electric motor 35 rotates the gear 45, and further rotates the roller 40, so that the conveyor belt 43 on the side of the product take-out device 130 runs in the direction of the arrow in FIG.

On the other hand, in the vending machine of this embodiment, the driving gear 46 attached to the roller 40 rotates with the rotation of the roller 40. Here, as described above, the lower arm 53
The power output gear 36 is maintained in a relative positional relationship with the drive gear 46 by the lower arm 53, and the power output gear 36 is always engaged with the drive gear 46. Further, a torque limiter 121 is interposed between the center shaft 66 provided on the lower arm 53 and the power output gear 36, and the power output gear 36 does not rotate below a certain torque. On the other hand, immediately after the product removal device 130 stops in front of the product mounting table 10 on which a desired product is mounted, the lower arm 53 is not in contact with any member. Therefore, immediately after the commodity removal device 130 stops in front of the commodity table 10 on which a desired commodity is placed, the lower arm 53 is free. It is in a state where free rotation is possible. Therefore, when the drive gear 46 is rotated immediately after the product removal device 130 stops in front of the product mounting table 10 on which a desired product is mounted, the power output gear 36 does not rotate, and the lower arm 53 holding the power output gear 36 does not rotate. As a result, the whole touches the power output gear 36 integrally.

The shaft 19 is engaged with the horizontal groove of the notch 59 of the lower arm 53 of the holding device 37, and the lower arm 5
With the rotation of 3, the power output gear 36 gradually approaches the power input gear 16 on the product mounting table 10 and finally comes into contact with the power input gear 16 on the product mounting table 10 side. Thus, the power output gear 36 provided on the lower arm 53 of the product take-out device 130 engages with the power input gear 16 of the product mounting table 10.

When the power output gear 36 engages with the power input gear 16 on the product mounting table 10 in this way, the power input gear 16 cannot revolve any further, and the lower arm 5
A large load torque is applied between the third central shaft 66 and the power input gear 16. As described above, the torque limiter 12 is disposed between the center shaft 66 of the lower arm 53 and the power input gear 16.
1, the torque applied to the power output gear 36 exceeds the transmission allowable range of the torque limiter 121 when the power output gear 36 is engaged with the power input gear 16, and the power output gear 36 It rotates relatively to the arm 53. That is, the power output gear 36 idles. As a result, the power output gear 3 in which the rotational force of the drive gear 46 runs idle.
The power is transmitted to the power input gear 16 on the product mounting table 10 via the motor 6 and the roller 11 on the product mounting table 10 rotates.

Also, in this embodiment, similarly to the previous embodiment, if the power output gear 36 and the power input gear 16 are disengaged for some reason, the lower arm 53 is rotated again and the power output gear 36 is rotated. 36 and the power input gear 16 are engaged. Then, by the action of the torque limiter 121, the power output gear 3
6 is engaged until the power input gear 16 is engaged, and the power output gear 36 is constantly pressed against the power input gear 16 with a constant force. Then, as in the previous embodiment, when the power input gear 16 on the product mounting table 10 rotates, the product mounting table 10 is rotated.
The conveyor belt 13 on the side runs, and the goods are paid out.

(Embodiment 5) Although the product mounting table 10 and the like employed in the above embodiments are all open on the front side, a structure in which a gate is provided on the front side in order to prevent the product from falling down. Is also recommended.

FIG. 18 is an explanatory view for explaining the operation of the XY transfer device of the vending machine according to another fifth embodiment of the present invention.
