To be more specific, a plurality of product holders are attached at equal intervals to an endless movable connecting band arranged in the vertical direction, and each time a sales signal is generated, the moving connecting band is moved in a fixed direction intermittently by the interval of the holders. This invention relates to a vending machine that is configured to rotate and drop products sequentially starting from the bottom.

The present invention is particularly suitable for vending machines for frozen products such as ice cream, and is designed to eject products so that even if the products freeze and adhere to the holding body, the products are forced to fall in addition to falling under their own weight. It provides equipment.

An embodiment of the present invention will be described in detail below with reference to the drawings.

First, (1) is a product storage column with a trowel-shaped cross section installed vertically inside the vending machine, and the side wall (IA) of the column (1)
Support shafts (2) and (3) are supported vertically and parallel to each other between (1B), and sprockets (4) and (5) are attached to each of the shafts, and sprockets (4) and (5) that face each other vertically. Endless chain belts (6) such as chains are stretched, and product storage shelves (7) each having a cross section are attached at predetermined intervals to the belts. A driving disk (9) fixed to an output shaft (8A) of a drive motor (8) capable of forward and reverse rotation is provided above the support shaft (3). Approximately triangular retaining parts (10) (11

Next, electrical control according to the present invention will be explained based on FIG. 8.

(35) (36) is the AC power line, (37) is the coin mechanism connected to the line (35) (3B), and when a designated coin is accepted, a sales enable signal is output from terminal 31 and the sale starts as described below. When the signal is input to the No. 6 terminal, the output of the sales enable signal is stopped. (38) is an instant return type product selection switch whose one end is connected to the line (36) and is used to select a product, and (39) is when the cobain mechanism (37) is emitting a sales ready signal. When the selection switch (38) is closed, the a contact of the full cycle switch (17) and the switch (40) described below are closed.
A) is energized via the b contact and its own switch (
39A> is a self-maintaining selection relay. The selection relay (39) is a switch (39A) (39B
(39C), and when excited, the coin mechanism (
37) via a switch (39C). (40) is a sell-out relay, which has a switch (40A>(40B>(40G)), and when the switch (42G) described below is closed, the line (3
When the sell-off switch (21) connected to 5) detects that the product is "absent", it closes and is energized. (41)
This is a loading switch that is operated when loading an i-product, and is set to the A side when reversing the drive motor (8), to the B side when rotating forward, and to the neutral position during normal sales. . When the loading switch (41) is turned to the reverse side, that is, to the a side, while the column 1 switch (21) connected to the line (36) is closed, the reverse relay (42) is energized. , the reversing relay (42) has one end connected to the a side contact of the loading switch (41), and the other end connected to the shelf position switch (21),
Switch (42A) (42B> (42C) (4
2D). The shelf position switch (21) is a switch that is operated by the product (Ml) in the storage shelf (1) loaded last when the motor (8) is reversed. (43) is a DC power supply that supplies power to the drive motor (8). The positive terminal of the power supply (43) is connected to the switch (42D) of the reverse relay (42).
) is connected to the switch (39B) of the selection relay (39) and the b-side contact of the loading switch (41), and the other end of the switch (41) is connected to the switch (40B) of the sold-out relay (40). A parallel circuit of a switch (420) and a switch (39B) is also connected to the switch (42A>).
) is the negative terminal of the reverse relay (42) switch (
42B). And the switch (42A>(42B) of the reverse relay (42) is both the drive motor (8)
This configuration is connected to both ends of the . (44) is a sold-out lamp that lights up when the product is sold out.

The operation of the above configuration will be explained below.

First, when a customer inserts a designated coin, the coin mechanism (
A sellable signal is issued from terminal 3 of 37). At this time, the full cycle switch (11) is operated so that the actuating member A (1B) is connected to the engaging portion (10) of the driving disk (9) as shown in Fig. 1.
Since the product (M) is not sold out and the sold-out relay (4G) is demagnetized, the switch (40A) is at the b contact. When the customer closes the product selection switch (38) in this state, the selection relay (39) connects the power line (35) - coin mechanism (31) - full cycle switch (11) - switch (
40A) - Selection relay (39) - Power line (36)
The switch (40A) is energized by the closed circuit of
Self-retained through contacts. Also, since the switch (40B) is closed, the positive terminal of the power supply (43) - the switch (40B) - the b contact of the switch (42A) - the drive motor (8) - the b contact of the switch (42B>-) - the power supply ( 43
) is formed to form an energizing circuit for the drive motor (8) at its negative terminal. Therefore, the driving disk (9) fixed to the output shaft (8A) of the motor (8) rotates, and the pin (12) of the engaging portion (11) is aligned with the radial groove (14) of the Geneva gear (13).
This Geneva wheel (13) is rotated clockwise while being fitted into the housing. When the circle W (9) rotates, the full cycle switch (17) changes to a B contact, so the switch (39G) is turned on by energizing the selection relay (39).
), the selection relay (39) continues self-holding via the full cycle switch (17) even if the sale ready signal is deactivated by sending the sale start signal to the No. 6 terminal of the coin mechanism (37). Therefore, the drive motor (8) remains energized. Then, as shown in Fig. 3, the dispensing lever (25) enters into the storage shelf (1), and as shown in Fig. 4, products such as ice cream (M
), the product will freeze and adhere to the storage shelf (1) and will not fall even if it is disengaged from the product support member (3G).

However, as shown in FIG. 5, the bottle (12) will eventually come into contact with the abutting member (32), causing the rotating member (19) to rotate clockwise. The actuating member B (20) also rotates against the spring B (23). At this time, the payout lever (25) also rotates clockwise,
Make an action to forcibly remove the product (M). Furthermore, although the shelf position switch (21) operates due to the rotation of the operating member B (20), there is no effect on the electric circuit. and bottle (12)
When the engagement between the contact member (32) and the contact member (32) is released, the spring B (
23), the actuating member B (20) etc. return to their original positions, and eventually the driving disk (9) rotates approximately 1@, the Geneva wheel (13) rotates 176 times, and the engaging portion (10) Rotate A (16) counterclockwise to return the full cycle switch (11) to the a contact point. Then, the self-holding circuit of the selection relay (39) is released, the energizing circuit of the drive motor (8) is also released, and the motor (
8) also stops, resulting in the state shown in FIG.

In this way, the product (M
) is running low and loading the product will be explained below.

In this example, when there are only three products (M) left,
shall be loaded. First, open the front door of the vending machine and turn the O-dead switch (41) provided on the back of the vending machine to the reverse side, that is, a@. Then, the reversing relay (42) is energized and switches (42A) (42B
) is changed to an a contact, the switch (42D) is closed, and the switch (42G) is opened.

Therefore, the positive terminal of the electric If (43) - switch (4
2D) - A contact of switch (42A) - Drive motor (
8) - 8 contacts of switch (42B) - Electric (43)
An energization circuit for reverse rotation of the motor (8) of the negative terminal of the motor (8) is formed, and the drive motor (8) begins to reverse rotation.

Then, the pin (12) of engagement 1!1 (11) is brought into contact with the contact member (
32) and against the spring D (34), the support shaft (33)
As shown in Fig. 6, the driving disk (9) rotates clockwise while simultaneously moving in the counterclockwise direction around Rotate the wheel (13) clockwise to remove the sprocket (
5) Reverse the endless chain belt (6) and store it in
(7), the support member (30) is moved by the spring C (
29) to operate the sell-out switch (27) so as to enter the storage space of the storage shelf (7). In this way, the drive motor (8) rotates several times and the last stored product (Ml) is delivered as l<-(25)! Support shaft (2
0A) Since it is rotated clockwise using the fulcrum, the shelf position switch (21) is released from the pressure by the actuating member B (20) and opens as shown in FIG. Then, the reversing relay (42) is demagnetized and its switch (42A) (42
B) is changed to a b contact and the switch (42D) is opened, so the reverse energization circuit of the drive motor (8) is released and the motor (8) is stopped. After that, when the loading switch (41) is switched from the reverse rotation side to the forward rotation side, the switch (40B) is closed because the sold-out relay (4o) is already excited, and the electric current [1 ( 43) positive terminal - B contact of loading switch (41) - Switch (40B) - B contact of switch (42A) - Motor (8) - Switch (42B) B contact - Negative terminal of power supply (43) An energizing circuit for normal rotation of the drive motor (8) is formed, and normal rotation starts this time. Then, the engagement between the product (Ml) and the payout t<'-(25) is released, and the lever (25) becomes approximately horizontal. Then, along with this normal rotation, the product may be loaded while moving the shelf to the storage shelf (7) where there is no product. Then, the lowest product (Ml) in FIG. 6 before loading comes into contact with the product support member (30) and rotates the member (30), so the sell-out switch (27) is activated by the operating member C (26). ) is in the product “available” state. Therefore, the sold-out relay (40) is demagnetized and its switch (40B> is opened to open the motor (8).
) is released and the motor (8) stops, resulting in the state shown in Figure 1. All you have to do is stop loading, set the loading switch (41) to the neutral state, and close the front 1m edge. It is something.

Since the present invention is configured as described above, when discharging the product, the product can be discharged under the product's own IIN, but even if it freezes and adheres to the product holder, the endless movable connection It is suitable for vending machines that handle frozen products and the like because it can be forcibly removed by a dispensing lever that is linked to a mechanism that drives the strip. Furthermore, the dispensing lever does not require a special driving source and is linked to the mechanism that drives the connecting band, so it can be manufactured at low cost.
