Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise unloading device for a vending machine, and more particularly to a lower pedal that does not return to a standby position for some reason. The present invention relates to a product delivery device of a vending machine which can prevent multiple products from being output with a simple structure even if a situation where the lock does not occur occurs. 2. Description of the Related Art Conventionally, there are provided various types of vending machine merchandise unloading devices. These vending machine merchandise unloading devices include a lower pedal for holding a lowermost product and an upper part thereof. And an upper pedal for holding the second product from the bottom when the product is carried out. The upper pedal is disposed at the lower part of the product path, and the pedals are alternately rotated and protruded toward the product path to control the product discharge. Is known. [0003] In other words, these product carrying devices regulate the size of the product passage depending on the presence or absence of the protrusion of the pedal (the amount of protrusion is always constant). May be provided in advance in the product passage with a member that regulates the width of the passage, or
This has been dealt with by providing a dedicated product unloading device that fits the size of the product. [0004] However, as is well-known, containers for canned beverages and PET bottled beverages are distributed in various shapes and outer diameters. If the product is to be sold in the same location of the product aisle, the width of the product aisle must be adjusted according to the product diameter. There was a problem that a case could arise. On the other hand, in order to sell products having different shapes and outer diameters without adjusting the product passage width, it is necessary to set the product passage width in advance in accordance with the product having the largest diameter. In order to sell a small-diameter product in the product path corresponding to the product, it is necessary to increase the protrusion amount of the product holding pedal described above. In order to drive the pedal against the product load applied to the pedal having the increased protrusion,
Although a driving device such as a solenoid having a large driving force should be provided, it cannot be provided because it is contrary to the recent demand for a thinner device, and there is a problem that the driving force becomes insufficient. Further, even if the lower pedal does not return to the standby position for some reason and the lower pedal is not normally locked, there is provided a means capable of preventing multiple products from being output with a simple structure. Was desired. The present invention has been made in view of the above, and it is possible to sufficiently secure the driving force of the upper pedal without increasing the size of the driving device, and to adjust the diameter of various diameters without adjusting the width of the product passage. In addition to providing a product unloading device for vending machines that can sell products, a simple structure can be used even if the lower pedal does not return to the standby position for some reason and the lower pedal does not lock normally. It is an object of the present invention to provide a vending machine product unloading device capable of preventing multiple products from being output. [0009] In order to achieve the above-mentioned object, a vending machine product carrying device according to the present invention comprises:
A lower pedal rotatably supported by the opening of the substrate and holding the first product from the bottom by projecting from the opening toward the product passage; and a rotatably supported by the opening of the substrate. An upper pedal that holds the second product from the bottom by projecting from the opening to the product passage side, and link means that reciprocates by a drive device to control opening and closing of the upper pedal and the lower pedal. An automatic vending machine which is formed so that products having different diameters can be carried out without changing the product passage width, and wherein the pedals are alternately protruded toward the product passage side to control the carrying out of the product. In the product discharge device of the machine, the rotation of the lower pedal is controlled via a stopper pin, and the rotation of the lower pedal is locked by engaging with a link pin provided on the link means. A rotation stopper formed so that the rotation of the lower pedal is restricted by the stopper pin and the maximum opening state of the lower pedal can be maintained, and the lower pedal is rotated by the rotation stopper itself. When the lower pedal is pressed by a product and is closed in a state where the lower pedal is not locked, an auxiliary stopper is provided which regulates the position of the stopper pin and prevents the rotation of the lower pedal. Therefore, even if the lower pedal cannot be returned to the maximum opening state for some reason and the drive device (solenoid) is de-energized and the lower pedal is pressed and closed by the product, the lower pedal is closed by the auxiliary stopper. Can be prevented, and a situation in which many products are taken out with the lower pedal kept open can be prevented.

First, the overall configuration of the product unloading device 1 will be described. As shown in FIG. 1, an opening 3 is provided in the substrate 2, and the upper pedal 4 and the lower pedal 5 for controlling the carry-out of goods are provided in the opening 3, and the substrate 2 and the bearing members 12,
13 is rotatably provided by pins 6 and 7 supported by the shaft. At the upper edge of the opening 3 of the substrate 2, there is provided a guide projection 2a for controlling the attitude of the product G by approaching it to a product exit passage plate 100 described later. The upper pedal 4 supports the second product G from the bottom when the lower pedal 5 is closed and the first product G from the bottom is dropped and carried out. (Polyacetal). The upper pedal 4 is urged in a closing direction by a torsion coil spring 8 mounted on the pin 6. As shown in FIGS. 1 to 4, the pin hole 4a of the upper pedal 4 is for inserting the pin 6. The stopper surface 4e of the stopper piece 4b comes into contact with the pin 22 at the time of the maximum opening of the upper pedal 4 to receive a product load applied to the upper pedal 4, and locks the position of the upper pedal 4 at the maximum opening. The guide piece 4c is erected at a predetermined interval from the stopper piece 4b, and slides the sliding groove 4d in which the pin 22 slides when the link member 19 reciprocates.
It is formed with. The escape groove 4f is formed so that the pin 22 does not hit the upper pedal 4 to prevent the closing operation when the upper pedal 4 is closed. The claw portion 4g is formed so as to engage with each other when the upper pedals 4 of the opposing product discharge device 1 are in a closed state when the product discharge device 1 having the same configuration is tied and installed, and the other upper pedal. 4 so as to ride on the upper edge. The relief hole 4h is provided in the commodity discharging device 1 having the same configuration.
When the upper pedal 4 of the opposing product unloading device 1 is in the closed state, the stopper piece 4b
Is formed so as not to increase the thickness of the entire apparatus at the time of installation. Also, the projection 4k
When the upper pedal 4 reaches the maximum opening degree, the upper pedal 4 comes into contact with a part of the bearing members 12 and 13 to regulate the rotation range. The locking hole 4m is for locking one end of the torsion coil spring 8. Next, the lower pedal 5 will be described. The lower pedal 5 holds the first commodity G from the bottom in the commodity passage 10 in the open state, and as shown in FIG. 5, a bearing stand 11 made of resin (for example, polyacetal) is provided on the back surface of the metal plate. It is configured with. The lower pedal 5 is urged by a torsion coil spring 9 mounted on the pin 7 in an opening direction (a direction protruding toward the product passage 10 shown in FIG. 7). The pin holes 5 a and 11 a of the lower pedal 5 are for inserting the pins 7. The locking claw 5 b is for locking the bearing base 11. The deformed groove 14 provided in the bearing base 11 slides an end of a pin 25 of a rotation stopper 20, which will be described later, so that the lower pedal 5 and the rotation stopper 20 are interlocked via the pin 25. Is formed in order to regulate the operation range. That is, the deformed groove 14 is formed of a small-diameter groove 14a that determines the lock position of the pin 25 and a large-diameter groove 14b that defines an operation range other than the lock position of the pin 25. A pair of guide projections 1 provided on the bearing stand 11
Reference numeral 5 is formed so as to sandwich both sides of the link member 19, and guides the link member 19 so that the vertical movement of the link member 19 does not shift in the left-right direction. The bearing stand 11 has a pair of auxiliary stoppers 60.
The auxiliary stopper 60 is provided with a contact surface 60 a that contacts the pin 25. The reason why such an auxiliary stopper 60 is provided is as follows. That is,
As shown in FIG. 13 to FIG. 16, there is a case where the commodity G is put in a standing state in the sales standby state, and the standing commodity G is, as shown in FIG. It takes more time to carry it out. Therefore, as shown in FIG. 18, although the lower pedal 5 starts to return to the state in which the product can be held after the product has fallen, it takes longer than usual. If the power to the solenoid 17 is cut off before the lower pedal 5 returns, the lower pedal 5 remains in a free rotation state and the upper pedal 4 is in the process of closing, so that the product has a sufficient holding power. I haven't. Therefore, neither pedal 4 nor 5 is in a state where goods can be held. For this reason, a large number of commodities are successively carried out, that is, a so-called multiple delivery occurs. In such a case, if the auxiliary stopper 60 is provided, the stopper surface 60a comes into contact with the pin 25 engaged with the small-diameter groove 14a of the rotation stopper 20, and
The pin 25 can be prevented from coming out of the small-diameter groove 14a. As a result, the locked state of the lower pedal 5 is maintained, and the occurrence of multiple rods can be prevented. In FIG. 7, the product exit passage plate 10
Numeral 0 is disposed opposite to the product carrying-out device 1 so as to have a passage width that can store a large-diameter product G. Product exit passage plate 1
The projecting portion 101 is provided to control a small-diameter product (not shown) such as a bottle product containing a so-called drink agent toward the upper pedal 4 side of the product carrying-out device 1 so as to easily hold the product. It is a thing. Next, the rotation stopper 20 will be described. The rotation stopper 20 locks the lower pedal 5 at the maximum opening so that the lower pedal 5 can receive the product load, and the lock is released when the product is sold, and the lower pedal 5 is moved into the opening 3 by the product load. By utilizing the force at the time of being pushed back and sliding the link member 19 upward via the pin 24, the solenoid 17 pulls the link member 19 to assist the driving force when the upper pedal 4 is opened. Things. The rotation stopper 20 is mounted on the bearing base 1.
Together with 1, the lower pedal 5 is formed so as to be supported so as to be substantially horizontal at the maximum opening degree. This is 2 from the bottom
Since the position of the second product G in the height direction differs depending on the diameter of the stacked products G, this difference is made as small as possible even when selling products G having different diameters, and the upper pedal 4 This is to ensure the holding in the. The lower end of the rotation stopper 20 is rotatably supported by a pin 23 held by the substrate 2 and the bearing members 12 and 13, and is opened by a torsion coil spring 40 mounted on the pin 23. Has been energized. Further, a pin 25 for locking the lower pedal 5 at the maximum opening is provided at the upper end of the rotation stopper 20. Both ends of the pin 25 are arranged in the deformed groove 14 of the bearing base 11 of the lower pedal 5, and when the lower pedal 5 is locked at the maximum opening, the pin 25 is moved to the small-diameter groove 14a of the deformed groove 14. At other times, the irregular groove 1
4 are located in the large-diameter groove portion 14b. Further, as shown in FIG.
The 0 pin holes 20a and 20b are for inserting the pins 23 and 25. The lock groove 20c is provided to lock the rotation of the rotation stopper 20 by engaging the pin 24. The locked state of the lower pedal 5, that is,
When the pin 24 is engaged with the lock groove 20c, the pin 25 is engaged with the small-diameter groove 14a. The inclined sliding surface 20 of the rotation stopper 20
“d” is formed so that the pin 24 slides when the rotation stopper 20 rotates. That is, the link member 19 is pulled by the solenoid 17 when the product is sold, and the pin 24
Is released from the lock groove 20c, the lock of the lower pedal 5 is released, and the lower pedal 5 is pushed back into the opening 3 by the product load. At this time, the rotation stopper 20 is also
Since the pin 24 is pushed back into the opening 3 around the center of rotation, the pin 24 slides upward by the inclined sliding surface 20d to move the link member 19 upward. Each of the above-mentioned members is formed and arranged so as not to interfere with the member of the counterpart when the product unloading device 1 having the same configuration is tied and installed. Next, the operation will be described with reference to FIGS. When the solenoid 17 is energized in the sales standby state shown in FIG. 7, the solenoid 17 pulls the link member 19 via the plunger 18. Then, as shown in FIG. 8, the pin 24 at the tip of the link member 19 comes off the lock groove 20 c of the rotation stopper 20. When the lock is released, the rotation stopper 20
The pin 25 at the upper end is also disengaged from the small-diameter groove portion 14a of the odd-shaped groove 14, so that the lock of the open state of the lower pedal 5 is released, and the lower pedal 5 can freely rotate to a predetermined rotation angle. Then, as shown in FIG. 9 to FIG.
When the lower pedal 5 is pushed back into the opening 3 by the load of the product G, the rotation stopper 20 is also pushed back into the opening 3 with the pin 23 as the rotation center, so that the pin 24 moves on the inclined sliding surface 20d. The link 25 is slid upward to move the link member 19 upward, and the pin 25 moves along the inner surface of the large-diameter groove 14b. At this time, the pin 22 engaged with the sliding groove 4d of the upper pedal 4 is also pushed up and the upper pedal 4 is opened, so that the force of the solenoid 17 pulling the link member 19 can be assisted. Thereby, even if the product is in contact with the upper pedal 4 and it is difficult to open, the turning power can be applied in the direction in which the upper pedal 4 opens, so that the upper pedal 4 becomes easy to open and the product G can be securely held. Then, as shown in FIGS. 11 to 12, when the product G falls and the product load is not applied to the lower pedal 5, the lower pedal 5 is opened by the urging force of the torsion coil spring 9. To return. Further, when the energization of the solenoid 17 is stopped, the link member 19 is pulled down by the urging force of the spring 30, the lock of the upper pedal 4 by the pin 22 is released, and the upper pedal 4 is closed by the urging force of the torsion coil spring 8. To return to the sales standby state (see FIG. 7). As described above, according to the vending machine product discharging device according to the present embodiment, the driving force of the upper pedal 4 can be sufficiently secured without increasing the size of the solenoid 17, so that the device can be made thinner. While selling products of various diameters. In particular, since the lower pedal 5 is provided with the auxiliary stopper 60, the lower pedal 5 cannot be returned to the maximum opening state for some reason, and the power supply to the solenoid 17 is cut off, and the lower pedal 5 is pressed and closed by the product. However, the auxiliary stopper 60 contacts the pin 25 and the lower pedal 5
Is prevented from rotating. Therefore, it is possible to prevent a situation in which a number of products are output while the lower pedal 5 is kept open. As described above, according to the merchandise unloading device of the vending machine according to the present invention, the merchandise unloading device is rotatably supported by the opening of the substrate and moves from the opening to the merchandise passage. A lower pedal that holds the first product from the bottom by projecting, and is rotatably supported by the opening in the board, and projects the product from the bottom to the product passage side to allow the second product from the bottom. An upper pedal to be held, and link means reciprocated by a drive unit to control opening and closing of the upper pedal and the lower pedal, so that products having different diameters can be carried out without changing the width of the product passage. In a product discharging device of a vending machine formed so that the pedals are alternately projected to the product passage side to control the discharging of the product, the rotation of the lower pedal is controlled via a stopper pin. And the rotation of the lower pedal is locked by engaging with a link pin provided on the link means, and the rotation of the lower pedal is restricted by the stopper pin so that the maximum opening of the lower pedal is adjusted. When the lower pedal is closed by being pressed by a product in a state where the rotation of the rotation stopper itself is not locked, the lower pedal includes a rotation stopper formed so as to be able to hold a state.
Since an auxiliary stopper is provided to regulate the position of the stopper pin and prevent the rotation of the lower pedal, the lower pedal cannot return to the maximum opening state for some reason, and the drive device (solenoid) is de-energized. Also, even when the lower pedal is pressed by the product and is about to be closed, the rotation of the lower pedal is prevented by the auxiliary stopper, and it is possible to prevent a situation in which many products are output while the lower pedal remains open.
