DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product discharging device for a vending machine.

[0002]

2. Description of the Related Art As a rotating drum portion that rotates in a semi-cylindrical shape, one disclosed in Japanese Patent Application Laid-Open No. 55-88194 is known. As a transporter, a transporter disclosed in JP-A-64-47709 is known.

[0003]

According to the configuration combining the above conventional techniques, there are the following problems.

[0004] The rotating drum unit and the transporting device must each have a drive unit, and it is necessary to have means for rotating the rotating drum unit by detecting that a product has been sent from the transporting device. Alternatively, the rotating drum portion must be controlled so as to receive the goods sent from the transfer device and rotated.

In addition, since the position of the product discharged from the rotating drum changes depending on the position of the product delivered from the transport device in the rotating drum, any position of the product discharged from the rotating drum should be adapted. The size of the product chute must be increased, that is, the internal space of the vending machine is restricted.

Accordingly, the present invention provides a method for driving a rotating drum and a transporting device by the same driving unit, and rotating the rotating drum in a manner to receive the goods sent from the transporting device. It is an object to make it possible to drive a rotary drum without a signal indicating that a product has been sent out, and to reduce the size of a product chute to increase the internal space of a vending machine.

[0007]

As a means for solving the above-mentioned problems, the present invention is directed to a commodity delivery table which is provided substantially horizontally and on which a commodity delivered from a storage section is placed. A conveying device provided with a reciprocating product conveying member for extruding and conveying the placed product; and a conveying device provided corresponding to one end of the conveying device, and the product

The product receiving portion (50) is in the shape of a circular arc, an opening is provided on an extension of the transporting device (4), and an inclined plate (51) is mounted inside the vending machine in a shape deeper on the front side. ing. The product receiving portion (50) is connected at its center to a rotating motor (54), and rotates forward and backward in synchronization with a product transporting member of the transport device by a driving force of the rotating motor (54). The driving force transmission gear (55) is connected to the product receiving portion (5).
0) and a rotation motor (54) are provided on an axis connecting the rotation and the rotation of the product receiving portion (50). The inclined plate (51) is curved in a shape in which a central portion is raised so that the product can be easily dropped by the rotation of the product receiving portion (50).

A gear 46 for transmitting the driving force to the conveying device 4 and a driving force transmitting gear 55 are connected to a driving force transmitting chain 60.
And is configured to drive the product conveying member 42 by the driving force of the rotation motor 54 ,
The gear 46, the driving force transmission gear 55, and the driving force transmission chain
The drive 60 drives the transport device 4 and the rotating drum 5 in conjunction with each other.
It functions as power transmission means.

When the commodity conveying member (42) is at the standby position at the left end when viewed from the front, the opening of the commodity receiving section (50) is in an upper horizontal state, and the commodity receiving section (50) is a rotating motor. When the product transport member (42) is rotated leftward in FIG. 1 by (54), the product transport member (42) moves rightward on the product transport platform (40), and the product is transported even when the product transport member (42) is moved to the right end. The amount of movement of the product transport member (42) is determined by the gear (46) and the driving force transmission gear (55) so that the product transport member (42) can be dropped onto the product receiving portion (50).

The operation of the vending machine according to the present invention having the above-mentioned structure will be described. First, when no goods are stored in the storage part (2), the lower part of the storage part (2) where no goods are stored is provided. The switch (37) of the commodity sending device (3) provided in the above rises and transmits a signal indicating that there is no commodity, and the commodity corresponding to the storage section (2) where no commodity is stored cannot be sold. Switch (3
7) Press down to enable sales.

When the user selects a product that can be sold and sends a sales command, the product delivery device (3) provided at the lower part of the storage section (2) that stores the selected product has two left and right sides.
The motors (36), (36) are driven. Since the directions of the motors (36) and (36) are opposite, the rotations of the motor (36) and the motor (36) are reversed to transfer the transfer chains (32) and (32) in the same direction. Further, the motors (36) and (36) rotate only in one direction in which the goods are sent to the transport device (4). Motor (3
6) and (36) are driven by the drive chains (35) and (3).
5), the drive sprockets (34) and (34) are rotated to drive the transfer chains (32) and (32) meshed with the drive sprockets (34) and (34). The transfer chains (32) and (32) are extrusion members (31).
The extruding member (31) transfers the lowermost product stored in the storage section (2) while extruding the product. When the goods pass through the switch (37), the switch (3)
7) rises, the pushing member (31) still continues to be transferred, and when the product is completely pushed out of the product loading table (30), the next stage product loaded in the storage section (2) falls. Depress the raised switch (37).

Then, based on the signal of the switch (37),
The rotation motor (54) of the rotation drum section (5) is driven, and the driving of the motor (36) is stopped.

In the commodity sending device (3), one of the pushing members (31) provided at equal intervals stops at the rear position of the commodity and enters a standby state.

The product extruded from the product delivery device (3) either directly enters the product receiving portion (50) or is delivered onto the product transport table (40) of the transport device (4).

The rotation motor (54) is driven to rotate the goods receiving portion (50) to the left, and in synchronization therewith, rotates the driving force transmission gear (55). The driving force transmission gear (55) rotates the driving force transmission sprockets (45) and (45) via the driving force transmission chain (60) and the gear (46) to drive the transport chains (43) and (43). Let it. The product transport member (42) is driven by the drive of the transport chains (43), (43).
Moves in the direction of the rotating drum portion (5), which is to the right.

Therefore, when a product is placed on the product transport stand (40), the product is transported to the product receiving section (50) by the product transport member (42).

The product entering the product receiving portion (50) is positioned on the front surface of the product receiving portion (50) by the inclined plate (51). The product receiving portion (50) rotates, and the product is carried out to the product chute (6) from the carry-out port (53). Since the inclined plate (51) has a curved shape with its central portion raised, it is easy to carry out the commodity to the commodity chute (6) without sticking to the inclined plate (51).

After the product is carried out, when the product receiving portion (50) is rotated to the position shown in FIG. 4, the product receiving portion (50) is rotated in the reverse direction by the reverse rotation of the rotating motor (54) so that the opening is horizontally moved upward. Returning to the standby state at the position, the goods transporting member (42) also moves to the left in synchronization with the reverse rotation of the goods receiving section (50) and enters the standby state.

[0029]

According to the present invention, the driving force transmitting means is used.
When the product is pushed out by the product transport member,
Part pivots to a position where it can accept the extruded product
The transfer device and the rotating drum are shared
Can be driven by a common drive source and
