Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a serpentine type product rack of a vending machine, and more particularly to a structure of a product rack in which the product passage width can be variably adjusted according to the diameter size of the product.

[0002]

2. Description of the Related Art Serpentine type product racks have been well known as product racks for vending machines that sell canned and bottled products. This serpentine type product rack has a meandering rack segment row formed by a pair of front and rear segment rows facing each other between left and right rack side walls, and is arranged on an extension of a lower end of the rack segment row so as to be located on the outlet side of a product passage. And a top tray that communicates with the top product tray, which is arranged in a line. The products stored side by side are delivered to one by the operation of the delivery mechanism.

By the way, the diameter size of a product for sale varies depending on the content capacity. A large capacity product has a large diameter size, and a small capacity product has a small diameter size. Therefore, when changing products for sale in the same product rack, widen the product aisle width in the rack for products with a large content volume, and conversely, increase the product aisle width for products with a small content volume. Narrowing is necessary for smooth delivery of goods.

On the other hand, as a measure against the above-mentioned problem, of a pair of rack segment rows defining a meandering product passage, one rack segment row is fixed to the rack side wall and the other is movable, and the movable side The rack segment row is superposed on the side wall of the rack and is attached to a connecting plate which is guided and supported so as to be movable in the horizontal direction, and the connecting plate is moved in the horizontal direction by interlocking with the above-mentioned outlet adjusting plate to move the product in the rack. A serpentine type product rack in which the passage width is variably adjusted according to the product diameter size is Japanese Patent Publication No. 58-165.
It is disclosed in Japanese Patent Publication No. 19 and is publicly known.

[0005]

The structure of the product rack disclosed in the above publication has the following problems in structure and operation.

(1) In order to move and adjust the connecting plate connected to the movable rack segment row in the horizontal direction by interlocking with the outlet adjusting plate, it is vertically guided across the connecting plate and the outlet adjusting plate. A supported operating plate is installed, and the operating plate, the connecting plate, and the outlet adjusting plate are linked and coupled through inclined long grooves and through pins, respectively, and move up and down in conjunction with the adjusting operation of the outlet adjusting plate. The movement of the operating plate is converted into the horizontal movement of the connecting plate to adjust the passage width.However, such a structure requires a large number of parts and complicates the rack structure, as well as mechanically. It is difficult to smoothly perform the linked operation.

(2) As an adjusting mechanism of the outlet adjusting plate, a locking pin for manually locking and releasing the outlet adjusting plate is provided, and the locking pin is provided in a pin hole of a plurality of adjusting steps drilled on the side wall of the rack. The width of the passage is variably adjusted by inserting it.
By the way, since there is not enough space inside the vending machine, normally the user puts his / her hand in the rack from the front and manually adjusts the outlet adjustment plate. It is extremely difficult to perform a fumbling operation without visually checking the steps and checking the position.

(3) When the product passage width is adjusted with the structure in which the through pin is inserted into the long groove opened on the side wall of the rack and the connecting plate, the metal parts rub against each other to cause wear and deformation, which results in long-term use. During the adjustment operation becomes less smooth.

(4) Further, the serpentine type product rack is provided with a top tray which communicates with the product insertion port on the upper part of the rack, and the replenished product is rolled on the top tray to be fed into the product passage in the rack. ing. However, if the top tray remains fixed, when the rack segment row is moved to adjust the product passage width as described above, the position of the top tray tip and the rack segment row will not match, and the top tray will be refilled. There is also a problem that it becomes impossible to smoothly transfer products from the top tray to the product passage in the rack.

The present invention has been made in view of the above points, solves the above-mentioned problems of the conventional structure, and reduces the number of parts, the width of the product passage in the rack and the position of the top tray with a simple adjustment operation. It is an object of the present invention to provide a serpentine-type product rack of a vending machine in which the product can be smoothly adjusted according to the product size.

[0011]

In order to solve the above problems, in the present invention, a product rack is constructed as follows.

(1) One of a pair of rack segment rows is fixed to the rack side wall, the other is movable, and a connecting plate which is vertically guided and supported is superposed on the left and right rack side walls, and the connecting plate is provided. The rack segment row on the movable side is suspended by the through pin passing through the inclined long groove formed in the above and the horizontal long groove formed in the rack side wall, and the lower end of the connecting plate is linked and connected to the outlet adjusting plate.

(2) One of a pair of rack segment rows is fixed to the rack side wall, the other is movable, and a connecting plate is provided which is superposed on the left and right rack side walls and is guided and supported diagonally in the vertical direction. The movable rack segment row is suspended by the through pin passing through the vertically elongated groove formed in the above and the horizontally elongated groove formed in the rack side wall plate, and the connecting plate is linked to the outlet adjusting plate.

(3) In the configurations of (1) and (2) above,
One of the through pins attached to the upper and lower two positions of the outlet adjusting plate and the connecting plate are linked and coupled, and the above-mentioned through pins are formed on the side wall of the rack with inclined guide grooves, and a plurality of adjustment steps arranged in parallel with the inclined guide grooves. The adjustment mechanism of the outlet adjusting plate is configured by being laid over each of the comb-shaped grooves having the.

(4) In the configuration of the above item (3), the inclined guide groove is a stepped groove in which the inclined groove portion and the vertical groove portion corresponding to each adjustment step are alternately arranged. The comb-shaped groove is composed of an oblique crossover groove portion and a branch groove portion branched downward from the crossover groove portion corresponding to each adjustment step, and a step is provided in the path of the crossover groove portion between the respective branch groove portions. I shall.

(5) In the construction of the above item (1), the connecting plate is guided and supported in the vertical direction with respect to the rack side wall by passing through the through pin between the pin hole formed in the rack side wall and the longitudinal groove formed in the connecting plate. As means for locking and holding the connecting plate at the corresponding position of each adjustment step, a notch step portion that engages with the through pin is provided at the groove edge of the longitudinal groove.

(6) In the configurations of (1) and (2) above,
An auxiliary connecting plate that straddles each through pin is provided outside the connecting plate so that the through pins supporting the movable rack segment row are interconnected.

(7) In the configurations of (1) and (2) above,
Sliding bearing members are attached to both ends of the through pin incorporated in the rack, and the through pin is guided and supported by the rack side wall and the groove of the connecting plate via the sliding bearing member.

(8) A top tray erected on the upper portion of the rack side wall plate through the product inlet is movably supported in the front-rear direction, and the tip is linked and coupled to the upper end of the movable rack segment row.

[0020]

In the above structure, when the position of the outlet adjusting plate is adjusted and moved stepwise along the comb-shaped groove in accordance with the diameter size of the product, the connecting plate is driven in conjunction with this, and the connecting plate further moves. By the movement, the through pin passing through the movable rack segment row moves along the horizontal long groove of the rack side wall plate. That is, the movable rack segment row moves horizontally in synchronization with the adjustment of the outlet adjustment plate, and the product passage width between the fixed rack segment row and the fixed rack segment row becomes a new passage width corresponding to the diameter size of the sold product. Adjusted to. In addition, the top tray linked to the upper end of the movable rack segment row is also moved and adjusted to a new position in conjunction with the product width adjustment operation.

Here, the stepped inclined guide groove formed on the side wall of the rack so as to guide and support the through pin attached to the outlet adjusting plate receives the product load applied in the direction of expanding the outlet adjusting plate at the vertical groove portion of the guide groove. And serves to prevent the outlet adjustment plate from being unduly displaced from its predetermined adjustment position. Regarding the comb-shaped groove that holds the other through pin attached to the outlet adjustment plate at each adjustment stage, the exit adjustment plate can be manually operated by providing a step in the path of the crossover groove between each adjustment stage. When moving the through pin along the in-groove path, it is possible to easily confirm the selection of each adjustment stage and the selected position by a feeling of the operation when the through pin crosses the step.

Further, the weight of the product stored in the rack acts to push the movable segment row away to enlarge the product passage, but the vertical edges of the vertical grooves for upper and lower guides formed on the connecting plate are different from each other. A cutout step portion that engages with the through pin is provided corresponding to the adjustment step, and the connecting plate is pressed against the through pin by using the pressing force due to the weight of the product, so that between the through pin and the cutout step portion. It is possible to prevent the connecting plate from being displaced by the binding force and prevent the product passage width from being changed unduly.

On the other hand, the auxiliary connecting plate attached to the connecting plate works to connect the through pins passing through the individual segments of the movable rack segment row to each other and prevent the through pins from moving apart. Therefore, even if there are some variations in the assembly dimensions or wear occurs in the long grooves of the connecting plate, the movable rack segment rows can be collectively and smoothly moved without being affected by the wear.

Further, the sliding bearing member attached to both ends of the through pin is a collared sleeve made of, for example, a resin having a small friction coefficient or a sintered alloy impregnated with lubricating oil. By interposing the member between the through pin and the long groove such as the rack side wall which is a sliding partner, the movement of the adjustment operation of the rack segment row becomes smooth, and the early wear of the sliding portion can be prevented.

It is fitted into the formed long groove from the outside and is used through the through pins 8 and 9 there.

Since the sliding bearing members 16 are attached to both ends of the through pin as described above, wear and deformation caused by direct sliding of the metal through pin and the metal rack side wall 1 and the connecting plate 7 as well as the metal through pin. Is avoided. As a result, the adjustment operation of the product passage width becomes smooth, and the life of the product rack becomes longer than that in the case where the sliding bearing member 16 is not used.

Next, FIGS. 16 and 17 show an embodiment corresponding to claim 9 of the present invention. In this embodiment, in the product rack described in the previous embodiment, when the product passage width in the rack is adjusted according to the diameter size of the product to be sold, the product insertion port is simultaneously operated in conjunction with this adjustment operation. The top tray provided is configured to be adjusted and moved to an appropriate position. Therefore, the front and rear ends of the top tray 13 which is erected on the upper portion of the rack side wall 1 through the product insertion port are moved in the front and rear direction through the through pin 9 in the horizontal long groove 1b formed in the rack side wall 1 corresponding to the top tray. It is movably installed, and the tip of the top tray 13 is connected to the uppermost segment of the movable rack segment row 4 via a through pin 9.

With this configuration, when the rack segment row 4 is moved in the front-rear direction by the same adjustment operation as described in the embodiment of FIG. 1, the top tray 13 also moves in the front-rear direction in association with the movement of the rack segment row 4. .. Therefore, the upper end of the movable rack segment row 4 and the tip of the top tray 13 are always kept at a constant relative position. That is, when the rack segment row 4 is moved to a new setting position so as to adjust the product passage width in the rack according to the size of the product to be sold, the top tray is also moved and adjusted to the new position at the same time. Therefore, it is possible to smoothly send the replenished product introduced from the product outlet to the product passage in the rack.
