Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a product delivery device for a vending machine.

Structure of a conventional example and its problems FIGS. 1 to 3 show a conventional product delivery device.

Reference numeral 1 denotes a side wall constituting the product storage section, which is formed in an abbreviated shape. Reference numeral 2 denotes a side wall erected facing the side wall 1 at a constant interval. 3 is a cylindrical product that comes into contact with the side wall 1 or 2 and is stored vertically. 4 is the above side wall 1
The rail supports the lower end of the rail, and is fixed to a pair of U-shaped channels 5 at the front and rear. A support plate 6 fixes the side wall 1 and the channel 5. Reference numeral 7 denotes a rotating shaft that is disposed parallel to the longitudinal direction of the side wall 1, is rotatably supported by a bearing 8 that is secured to the support plate 6, and is rotated in one direction. 9 is a star foil type product stopper having three protruding pieces 9a, 9b, and 9c, and the space between each protruding piece is formed in an arc shape. 10 is a shooter that guides product 3 to the exit.
The product stopper 10 is disposed below the product stopper 10. 11
is a drive device consisting of a motor that operates for a certain period of time in response to an electric signal, and is directly connected to the rotating shaft 7 and rotates every 120 degrees.

Next, its operation will be explained. A indicates a state in which the product 3 is expected to be sold, and the product 3 is in contact with one of the protruding pieces 9a of the product stopper 9, preventing the product from falling. Next, when an electric signal is transmitted to the sales drive device 11 (by the operation of a selection switch (not shown) after the customer has inserted a predetermined number of coins), the rotating shaft 7 rotates (in the direction a in FIG. 3), and the When the product 3 rotates to state B in FIG. 3, the protruding piece 9a of the product stopper 9 is released from contact with the product 3, and the product 3 falls downward. At this time, the next product 3' comes into contact with the tip of the other protruding piece 9b of the product stopper 9, and is prevented from falling. Next, the rotation progresses and the product stopper 9 returns to the product waiting state (normal state).

However, in the above configuration, as the stored products become larger, the arc between the protruding pieces of the product stopper becomes larger (
If the arc of the product stopper is smaller than the arc of the product's outer periphery, the product aisle [1] will become wider and the product delivery device will become larger. There is a certain relationship between the size of the product and the length of the protruding piece, and there is a certain relationship between the size of the product and the length of the protruding piece, and products with different diameters will change the contact position of the tip of the piece, causing the product to get stuck and making it impossible to carry out smoothly. It had the disadvantage that it could not be sold.

OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to make it possible to sell various cylindrical products with different diameters.

Structure of the Invention In order to achieve this object, the present invention provides a main shaft below a pair of front and rear fixed plates, a pair of rotating plates having a plurality of arc-shaped long holes on the main shaft, and a pair of rotating plates having a plurality of arc-shaped long holes between the long holes of the rotating plates. By attaching a stopper that comes into contact with the product in a loose fit and biasing this stopper toward one side of the long hole with a spring, the stopper for the next product to be sold comes into contact with the product to be sold and moves the long hole. The purpose is to carry out a smooth product transport operation regardless of the diameter of the product being sold.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 6.

In addition, the same numbers are attached to the same configuration as the conventional example,
A detailed explanation thereof will be omitted.

Reference numeral 12 denotes a pair of front and rear rotary plates disposed between the support plates 6, which are locked to the main shaft 7, and have four arc-shaped long holes 12a, and two protruding pieces 12b facing each other at 180 degrees. It is installed as follows. 13 is the elongated hole 1 of the pair of rotary plates 12
This is a stopper that is loosely inserted and supported between 2a. 14′.

14", 141#, 14"" is the above stopper 13
This is a product stopper projecting piece that is locked to the main shaft 7 and is tapered from the main shaft 7 toward the stopper 13 . Reference numeral 15 denotes a tension spring that is engaged with the projection piece 12b of the rotary plate 12 and the stopper 13, and a stopper is provided on the right end surface of the elongated hole 12a (at a position where it is possible to prevent the product from falling) when viewed from the center of the rotary plate 12. 13 are urged so that they come into contact with each other, and the opposing stoppers 13 are attached to the protruding pieces 12b of one rotary plate 12, respectively.

To explain the operation in the above configuration, FIG. 6A shows the sales waiting state, in which the product stopper protruding pieces 14', 14'' are in contact with the product 3, and in particular, the product stopper protruding piece 14' supports the product. Next, when the drive device is actuated by an electric signal at the time of sale, the main shaft 7 and the protruding piece 14' rotate in the direction of the arrow in the figure, resulting in the state shown in Fig. 6. At this time, the protruding piece 14'
' is the rotary plate 12 while maintaining the tip end position of the elongated hole 12a of the rotary plate 12 (because it is urged by the tension spring 15).
Rotates in sync with 0 rotation. The protruding piece 14'' also rotates in the same way, but at this time, if the diameter of the product 3 is large, the angle at which the product 3 contacts the protruding piece 14' is widened (in the opposite direction to the rotating direction of the rotary plate 130 in the figure). product 3)
It comes into contact with product 3. Next, as the selling operation progresses, when the product passage becomes wider than the diameter of the product as shown in FIG. 6C, the contact between the product 3 and the protruding piece 14' is released, and the product 3 falls downward. At this time, the protruding piece 14'' comes into contact with the product 3 and maintains a position that prevents the next product 3' from falling, and as the rotary plate 12 further rotates, it prevents the next product 3' from falling due to gravity. The products 3' are brought into contact with each other in such a manner as to stop the product 3'.When the operation proceeds next, the product returns to the sales waiting state as shown in FIG. 6A.

As a condition, the force of the tension spring 15 is set to be weaker than the weight of the product.

Therefore, since each protruding piece is arranged so as to be movable in only one direction, the protruding piece always comes into contact with the outer periphery of products with different diameters from the start to the end of the sales operation, and furthermore, the next product can be completely prevented from falling. It has the effect of being able to. - In the embodiment, the projecting pieces 14', 14''.

14'' and 14"" are in contact with the product 3, but the same effect can be obtained even if the stopper 13 is in contact with the product 3.

Effects of the Invention As described above, since the product discharging device of the present invention allows the stopper to move within the elongated hole of the rotary plate, it is possible to sell a variety of products with different diameters. In addition, since the stopper is moved by springing into contact with the product to be sold, when the next part comes to the sales position, the stopper is positioned below the product, completely preventing the next product from falling, and is a versatile product. It is possible to carry out the transportation of products with ease.
