[Prior art]
2. Description of the Related Art Conventionally, various vending machine merchandise unloading devices have been provided. These vending machine merchandise unloading devices are provided with a lower pedal for holding a lowermost product and an upper position of the lower pedal. An upper pedal for holding the second product is provided at the lower part of the product passage, and these pedals are alternately rotated and protruded toward the product passage to control the delivery of the product.
[0003]
In other words, since these merchandise carry-out devices regulate the merchandise passage dimensions based on the presence or absence of the pedal protrusion (the projection amount is always constant), when selling products with different shapes and outer diameter dimensions, In order to cope with this problem, a member that regulates the width of the passage is separately provided in the product passage, or a dedicated product carry-out device adapted to the product dimensions is provided.
[0004]
[Problems to be solved by the invention]
However, as is well known, containers for can drinks and plastic bottle drinks are distributed in various shapes and outer diameters, so if you try to sell products with different outer diameters at the same location in the product passage The product passage width has to be adjusted in accordance with the product diameter, which is troublesome, and depending on the shape of the container, there is a problem that it may not be suitable for the mechanism of the product carry-out device and may not be sold.
[0005]
On the other hand, in order to sell products with different shapes and outer diameters without adjusting the product passage width, it is necessary to set the product passage width according to the product with the maximum diameter in advance. In order to sell a small-diameter product in the combined product passage, it is necessary to increase the protruding amount of the above-mentioned product holding pedal.
[0006]
Then, it is required to securely lock the pedal in the open state against the product load applied to the pedal with the increased protrusion amount. However, there has been a problem that the product holding position set in advance cannot be maintained due to the deformation of the product due to the product load, and it may be difficult to maintain the upper pedal in the open state.
[0007]
The present invention has been made in view of the above, and can sufficiently secure the driving force of the upper pedal without increasing the size of the driving device, and can sell products of various diameters without adjusting the width of the product passage. The purpose is to provide a vending machine product unloading device, and in particular, to provide a vending machine product unloading device that can hold the product securely even if the upper pedal does not protrude completely. The purpose is to do.
[0008]
[Means for Solving the Problems]

[0013]
As shown in FIG. 2 , an opening 3 is provided in the substrate 2 of the product carry-out device 1, and an upper pedal 4 and a lower pedal 5 for controlling product carry-out are connected to the substrate 2 and the bearing in the opening 3. It is rotatably provided by pins 6 and 7 pivotally supported on the members 12 and 13. A guide protrusion 2a is provided at the upper edge of the opening 3 of the substrate 2 for controlling the attitude of the product G toward the product outlet passage plate 100 described later (see FIG. 7 and the like).
[0014]
The upper pedal 4 supports the second commodity G from the bottom when the lower pedal 5 is closed and the first commodity G from the bottom is dropped and carried out (see FIG. 11). For example, it is integrally molded with polyacetal. The upper pedal 4 is biased in a closing direction by a torsion coil spring 8 attached to the pin 6.
[0015]
As shown in FIGS. 1 to 4, the pin hole 4 a of the upper pedal 4 is for inserting the pin 6. The stopper surface 4e of the stopper piece 4b is in contact with the pin 22 when the upper pedal 4 is at the maximum opening, receives 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 from the stopper piece 4b at a predetermined interval (an interval larger than the diameter of the pin 22), and when the link member 19 reciprocates, the sliding groove 4d in which the pin 22 slides is provided as a stopper piece. It is formed together with 4b.
[0016]
The sliding groove 4d is provided with a stopper step 4r so that the pin 22 can be engaged and the locked state can be maintained even if the upper pedal 4 does not protrude completely. The reason why the stopper step 4r is provided is as follows. That is, in the sales standby state (see FIG. 7), the first product G from the bottom and the second product G from the bottom are deformed (deformation due to the load of the stacked products or deformation from before the storage). In some cases, the timing at which the product contacts the upper pedal 4 is accelerated. In such cases, when the upper pedal 4 does not protrude to the original maximum opening degree condition, it is difficult to hold the goods.
[0017]
In order to solve this problem, a stopper step 4r is provided in the sliding groove 4d of the upper pedal 4, and as shown in FIG. 10, even if the upper pedal 4 does not protrude completely, the pin 22 remains in this stopper step. It is engaged with 4r and the locked state is maintained, so that the product can be held.
[0018]
Further, the relief groove 4f is formed so that the pin 22 hits the upper pedal 4 when the upper pedal 4 is closed and does not hinder the closing operation. The claw portion 4g is formed so as to mesh with each other when the upper pedal 4 of the product unloading apparatus 1 facing the nail portion 4g is closed when the commodity unloading apparatus 1 having the same configuration is entangled and installed. 4 is formed so as to ride on the upper edge portion.
[0019]
The escape hole 4h allows the tip of the stopper piece 4b to escape when the upper pedal 4 of the commodity unloading apparatus 1 that is opposite is closed when the commodity unloading apparatus 1 having the same configuration is laid and installed. It is formed so that the thickness of the entire apparatus does not increase. Further, the protrusion 4k is for abutting against a part of the bearing members 12 and 13 to restrict the rotation range when the upper pedal 4 is in the maximum opening degree. The locking hole 4 m is for locking one end of the torsion coil spring 8.
[0020]
Next, the lower pedal 5 will be described. The lower pedal 5 holds the first product G (see FIG. 7) from the bottom in the product passage 10 in the open state. As shown in FIG. 5, a resin (for example, polyacetal) is placed on the back surface of the metal plate. A bearing stand 11 made of metal is provided. The lower pedal 5 is biased in the opening direction by a torsion coil spring 9 attached to the pin 7.
[0021]
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 the end portion of the pin 25 of the rotation stopper 20 which will be described later, and the pin 25 is connected to the lower pedal 5 and the rotation stopper 20 via the pin 25. This is formed in order to regulate the operation range. That is, the deformed groove 14 is formed of a small diameter groove portion 14 a that defines the lock position of the pin 25 and a large diameter groove portion 14 b that defines an operation range other than the lock position of the pin 25.
[0022]
The pair of guide protrusions 15 provided on the bearing base 11 are formed so as to sandwich both sides of the link member 19 and guide the link member 19 so that the vertical movement of the link member 19 does not shift in the left-right direction.
[0023]
In FIG. 7, the product outlet passage plate 100 is disposed so as to face the product carry-out device 1 so as to have a passage width that can accommodate the large-diameter product G. The protrusion 101 of the product outlet passage plate 100 is controlled so that a small-diameter product (not shown) such as a bottle product containing a so-called drink agent is brought close to the upper pedal 4 side of the product carry-out device 1 to easily hold the product. It is provided to do.
[0024]
Next, the rotation stopper 20 will be described. 2, 3, and 6, 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. The solenoid 17 pulls the link member 19 by using the force when the lower pedal 5 is pushed back into the opening 3 by the product load, and slides the link member 19 upward via the pin 24. This is for assisting the driving force when opening 4.
[0025]
Further, as shown in FIG. 7 and the like, the rotation stopper 20 is formed so as to support the lower pedal 5 together with the bearing base 11 so as to be substantially horizontal at the maximum opening. This is because the position in the height direction of the second product G from the bottom varies depending on the diameter of the stacked products G, so that this difference is as small as possible even when selling products G having different diameters. This is to ensure that the upper pedal 4 is held.
[0026]
The rotation stopper 20 is pivotally supported at its lower end by a pin 23 held by the substrate 2 and the bearing members 12 and 13, and is urged in the opening direction by a torsion coil spring 40 mounted on the pin 23. Has been. 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.
[0027]
Both ends of the pin 25 are disposed 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 positioned in the small diameter groove portion 14 a of the deformed groove 14. In other cases, it is positioned in the large-diameter groove portion 14b of the deformed groove 14.
[0028]
Further, as shown in FIG. 6, the pin holes 20 a and 20 b of the rotation stopper 20 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. When the lower pedal 5 is locked, that is, when the pin 24 is engaged with the lock groove 20c, the pin 25 is engaged with the small diameter groove portion 14a.
[0029]
The inclined sliding surface 20d of the rotation stopper 20 is formed so that the pin 24 slides when the rotation stopper 20 is rotated. That is, when the link member 19 is pulled by the solenoid 17 and the pin 24 is removed from the lock groove 20c when the product is sold, the lower pedal 5 is unlocked and the lower pedal 5 is pushed back into the opening 3 by the product load. .
[0030]
At this time, 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 slides upward by the inclined sliding surface 20d and moves the link member 19 upward. It has become.
[0031]
In addition, each member mentioned above is formed and arrange | positioned so that it may not interfere with the member of the other party, when tying and installing the goods carrying-out apparatus 1 of the same structure.
[0032]
Next, the basic operation will be described with reference to FIGS. In the sales standby state shown in FIG. 7, when the solenoid 17 is energized, 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 is released from the lock groove 20 c of the rotation stopper 20.
[0033]
When this lock is released, the pin 25 at the upper end of the rotation stopper 20 is also released from the small-diameter groove 14a of the deformed groove 14, and the unlocked state of the lower pedal 5 is released, so that the lower pedal 5 is free to a predetermined rotation angle. It can be turned.
[0034]
9 to 11, when the lower pedal 5 is pushed back into the opening 3 by the load of the product G, the turning stopper 20 is also pushed back into the opening 3 with the pin 23 as the turning center. Therefore, the pin 24 slides upward on the inclined sliding surface 20d to move the link member 19 upward, and the pin 25 moves along the inner surface of the large-diameter groove portion 14b.
[0035]
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 it is a case where goods contact | abut on the upper pedal 4 and it is hard to open, since turning force can be provided in the direction which the upper pedal 4 opens, the upper pedal 4 becomes easy to open and the goods G can be hold | maintained reliably.
[0036]
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 returns to the open state by the urging force of the torsion coil spring 9. Further, when the energization of the solenoid 17 is turned off, the link member 19 is pulled down by the biasing force of the spring 30 and the lock of the upper pedal 4 by the pin 22 is released, and the upper pedal 4 is closed by the biasing force of the torsion coil spring 8. To return to the standby state (see FIG. 7).
[0037]
As described above, according to the commodity carry-out device of the vending machine according to this 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 thinned. However, products of various diameters can be sold.
[0038]
In particular, by providing the stopper step 4r in the sliding groove 4d of the upper pedal 4, the upper pedal 4 can be kept locked even when the upper pedal 4 is not completely projected, and the product can be reliably held.
[0039]
