Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vending machine, and particularly to an improvement of a so-called rotary vending machine in which a product loading body is rotatable.

2. Description of the Related Art A vending machine is known in which a rotatable product loading body is built in and partition plates are provided at predetermined intervals in the circumferential direction of the product loading body.

The drive source of the product loading body is activated by a coin, and the product loading body is intended to stop at a fixed position.
Normally, a cam detection means is used as a detection means for stopping at a fixed position.

According to this cam detection means, in order to apply it to the size of the product to be sold, the stocker width is varied according to the size of the product, so the cam detection means also needs to be designed according to the stocker width. This has the disadvantage of high production costs, and also has the disadvantage that machining errors and incorrect assembly position adjustment can lead to malfunctions.
The present invention detects when the product loading body stops at a fixed position and feeds the detection signal back to the drive source of the product loading body, thereby loading the product regardless of the size of the stocker, that is, the size of the product. In addition to being able to dispense products by stopping the machine in a fixed position, it also eliminates problems caused by processing errors and incorrect assembly position adjustment.In addition, the drive source is built into the product loading body, which increases the space advantage. It is an object of the present invention to prevent a drive source from generating excessive heat even if the drive source is Hereinafter, specific examples of the present invention will be described in detail with reference to the drawings.

In FIGS. 1 and 2, which schematically show the internal structure of a vending machine as a front and side view, reference numeral 1 indicates an exterior case of the vending machine, and 2 indicates an opening/closing door of the vending machine.

Although the outer case 1 is illustrated in FIG. 7 as being box-shaped, its shape may be arbitrary. Further, the opening/closing structure of the opening/closing door 2 is arbitrary, such as single opening or double opening. With the opening/closing door 2 side being the front side and the inner part being the back side, a pair of support brackets 3 and 4 are fixed to the middle of the front side and the back side of the exterior case 1 from the lower part of the height direction of the exterior case 1. has been done. A base 5 is fixed between the support brackets 33 and 4, and the front side of the base 5 is opened and a chute 6 is inclined toward the opening/closing door 2.
is provided. As particularly illustrated in FIG. 2, the products that have been guided down through the chute 6 are taken out as before through the product take-out section 7, a product receptacle (not shown) provided in the opening 8 of the opening/closing door 2, etc. Ru. 9 is a product loading body, which is drum-shaped.

When forming the product loading body 9 into a drum shape, in a specific example, as illustrated in FIGS. 3 and 4, cylindrical bodies 11 are attached to a disk 10 through angles 12 arranged at predetermined intervals in the circumferential direction, and screws, etc. A ring plate 14 is fixed to the outer periphery of the other end of the cylindrical body 11 via angles 13 similarly arranged at predetermined intervals in the circumferential direction using screws or the like. The outer circumferential edge of the disk 10 and the outer circumferential edge of the ring plate 14 are substantially on the same plane, and the disk 10 and the ring plate 14 substantially face each other in the outer region of the cylindrical body 11. Since the ring plate 14 is provided on one side of the cylindrical body 11, a vacant chamber 15 which is open on one side is defined in the inner core of the drum-shaped product loading body 9. The outer area of the cylindrical body 11 is substantially formed as a product loading section, and as shown in the figure, partition bodies 16 are detachably provided at predetermined intervals in the circumferential direction. That is, the slits 17 are formed in the cylindrical body 11 at equal intervals in the circumferential direction, and the mounting holes 18 are also formed in the disk 10 and the ring plate 14 at equal intervals in the circumferential direction. are fitted into the slits 17 of the cylindrical body 11, and both sides of the partition body 16 are attached by screwing screws 19 into the attachment holes 18. A large number of slits 17 in the cylindrical body 11, mounting holes 18 in the disk 10 and the ring plate 14 are provided at predetermined intervals in the circumferential direction, and since the partitioning body 16 is detachable from these, the size of the product, A stocker part that is optimal for the shape can be formed. In other words, the partition 16 is adjusted and attached in the circumferential direction. Although the partitioning body 16 is detachable from both side walls using screws 19, it is also possible to form dowels in the partitioning body 16 to fit them. As shown in the drawings, especially FIG. 3, the partitions 16 have a triangular shape in side view, and dowels 17a are formed at the acute corners of the partitions 16 to fit into the slits 17, so that the adjacent partitions 16 form a rectangle. A shaped stocker section is formed.

Note that if the partitioning body 16 is assembled in the opposite direction to that shown in the drawings, a stocker portion that expands radially outward will be formed, and the products will be dispensed radially outward, so the size may vary depending on the type of product. may be advantageous. In addition, although the outer edge of the partition body 16 and the outer edges of the disk 10 and the ring plate 14 are made to coincide with each other in the figure, even if the partition body 16 is made to protrude radially outward, the outer edge of the partition body 16 may instead be projected radially inward. It may be something that has been incorporated. The partition body 16 is made of plastic material, and the fourth
As shown in the figure, a recessed cutout 20 is cut out at the outer edge. Of course, the partition body 16 can be made of a metal material, but a plastic material is preferable. Further, although a solid structure may be used, a hollow structure is advantageous in consideration of weight reduction and driving force. In FIG. 4, reference numeral 21 denotes a drum frame, the lower part of which is supported on the fixed side like the base 5 as shown in the first drawing, and the upper part supported by a support member 22 as shown in the first drawing. In short, it is supported on the fixed side.

As shown in the fourth figure, this drum frame 21 is located on the opposite side of the product loading body 9 from the disk 10, and a motor support bracket 23 is fixedly installed at a portion substantially facing the internal cavity 15 of the product loading body 9. A drive motor 24, which is an example of a drive source, is supported on this support bracket 23. Fourth
As particularly illustrated in the figure, the motor support bracket 23 is arranged in a space 15 of the product loading body 9, and the drive source 24 is housed in the space 15.

The output shaft 25 of the drive source 24 is mounted on the bearing 2 at the center of the product loading body 9.
The drum-shaped product loading body 9 can be rotated for dispensing when the drive source 24 is activated.
Although the output shaft 25 is substantially fixed to the disk 10, the drive source 24 may be located unevenly within the cavity 15 as long as the output shaft 25 is located in the center of the drum-shaped load 9. In any case, the drum-shaped product loading body 9 has a radially divided product loading section on the outer periphery, and the inner core has a disc 10 with one side open and the other side closed. A support bracket 23 attached to the drum frame 21 is extended into the cavity 15 in a crowded manner, and a drive source 24 is connected to the support bracket 23.
is supported, and its output shaft 25 is connected to the bottomed part of the concave cavity 15.

In FIGS. 3 and 4, reference numeral 27 denotes a product receptacle, which is provided on the drum frame 21.

As particularly illustrated in FIG. 3, the product receiver 27 has a semicircular shape surrounding the outer area of the lower half of the product loading body 9, and has a width greater than the width of the drum-shaped product loading body 9. Therefore,
The product A is loaded into the product loading section B divided by the partition body 16, and even if the product loading body 9 rotates, the product A is received without falling. A product drop port 28 is formed near the deepest part of the product receptacle 27, and the chute 6 is provided below the product drop port 28 in a corresponding manner.

29 is a gate, and as shown in FIG.
The product drop port 28 can be opened and closed via A.

That is, when the door 2 is closed, the upper part 29B of the link mechanism 29A is pushed by the door 2, and the gate 2 is moved around the fulcrum 29C.
9 opens the product drop port 28, and when the opening/closing door 2 is opened, the gate 29 advances through the product drop port 28 centering on the fulcrum 29C as shown by the chain line in Figure 2 and closes it. . In FIG. 3, the reference numeral 30 is a detection means for stopping the product loading body 9 in a fixed position, and the solid line in FIG. What is shown by the chain line in FIG. 3 is for detecting the main body of the partition body 16, and any means may be used.
In the first embodiment, the drum base 21 is provided with a switch operating link 32 that swings about a pivot 31, which is elastically pulled by an elastic spring 33 and regulated by a stopper 34. At this time, it is separated from the microswitch as the detector 35, and when the product loading body 9 rotates and comes to a fixed position, the screw 19 or dowel resists the spring 33 and swings the switch actuating link 32 to detect it. The device 35 is activated to automatically stop the drive source 24. The second embodiment is basically the same, except that the switch actuator 35a of the detector 35 can come into direct contact with the partition 16. As mentioned above, cam detection means has been conventionally used as this type of detection means, but when applied to a wide variety of products,
It is necessary to set the cam shape accordingly, and there is also the disadvantage that a unique cam detection member is required depending on the size of the product to be sold. In this regard, according to the detection means of the present invention, two embodiments of which are shown in FIG. This has the advantage that position detection can be performed regardless of any changes made. In addition, position detection will not become inaccurate due to processing errors or malfunctions due to incorrect assembly position adjustment, and the advantage is that the position can be detected using the same method regardless of the size or type of product. There is.

In FIG. 3, reference numeral 36 indicates a microswitch as a product sold-out detector, which is installed on the drum base 21, and its actuator 37 protrudes from the concave cutout 20 of the compartment body 16 to directly detect the presence or absence of the product. is being detected. According to the present invention configured as described above, the driving source 2 can be
4 is activated, the product loading body 9 is rotated around the horizontal axis in the specific example.

As the product loading body 9 rotates, the product A stored in the loading section B is carried around.
0 is provided, the detection means 30 detects the position where the product A in the loading section B corresponds to the drop port 28 and feeds it back to stop the drive source 24, thereby stopping at the appropriate position. . Then, the product A falls under its own weight, passes through the chute 6 and the product outlet 7, and is discharged into the product receiving tray. Accordingly, in the present invention, the product loading body 9 itself is detected by the fixed position stop detection means 30, and this is detected by the drive source 24.
Even if the loading part B changes depending on the size and shape of the product, it can be detected in any position regardless of the change in the detection position, and the same means can be used to detect a wide variety of It can be applied to the model, and in addition, processing errors,
Even if there is an assembly error, the final rotating portion is equivalently detected, so there are no detection errors. 7
A drum frame is provided on the open side of the concave cavity, and a support bracket attached to this frame is extended into the cavity in a crowd-like manner, and a drive source is supported on the support bracket to drive the output shaft of the drive source. Because it is connected to the bottomed part of the concave cavity,
The product loading body can be stably supported even though it is supported on a cantilever, and the drive source can be double protected by the product loading body and the support bracket, and the drive source can be stored in an empty room. Since the empty space is open on one side, heat is less likely to be trapped in the empty room.
