Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a product storage rack of a vending machine for storing cylindrical products such as canned juice and canned coffee in the vending machine prior to sale.

[0002]

2. Description of the Related Art Recently, canned juice, canned coffee, etc.
There is a tendency to sell multiple types of products with different can diameters, such as small cans represented by 250 mml cans and thick cans represented by 350 mml cans, with a single vending machine. In such a vending machine, each column of the product storage rack can be appropriately changed and adjusted for thin cans or thick cans. This change adjustment is generally performed by adjusting the passage width (height) of the product passage forming the column to be narrow or wide, or by adjusting the width (height) of the product inlet.

As a conventional product storage rack for adjusting the width of such a conventional product passage, for example, Japanese Utility Model Publication No. 64-277.
The one described in Japanese Patent No. 68 is known. Each column of this product storage rack has a product inlet at the front end for loading cylindrical products in a horizontal position, a horizontal stock passage extending diagonally downward and backward from the product inlet, and a rear end of the horizontal stock passage. A vertical stock passage that extends downward through the bend,
A merchandise passage including a merchandise dispensing port provided at the lower end of the vertical stock passage is provided.

The product passage is provided with a top plate which constitutes a horizontal stock passage. The top plate is supported by the left and right side plates of the product storage rack so as to be able to move forward and backward, and the rear end is the upper end of the vertical stock passage. It is configured so that the passage width of the upper end of the vertical stock passage can be adjusted to be wide or narrow for thin cans or thick cans. That is, when filling a large can in the product passage, the top plate is moved so as to be pulled forward to widen the passage width at the upper end of the vertical stock passage, and when filling a small can, the top plate is moved backward. The width of the vertical stock passage can be narrowed by moving it so that it is pushed in.

On the other hand, as a product storage rack for adjusting the width of the product insertion port, for example, one disclosed in Japanese Utility Model Publication No. 64-39581 is known. In this product storage rack, a supporting member is fixed to both side plates and is positioned above the front end portion of the top plate, and the supporting member has long legs and short legs. Is supported. The dosing restriction member is configured to be movable with respect to the support member between a large can setting position in which the short legs hang down from the support member on the top plate and a thin can setting position in which the entire short length hangs from the support member onto the top plate. Therefore, the charging control member is moved as appropriate according to the diameter of the product to be charged, and the setting is made for thin cans or thick cans.

[0006]

By the way, in the case of the structure in which the width of the product insertion port is set for thin cans or thick cans such as the latter product storage rack, both vertical and horizontal stock passages are always provided. Since it is set for thick cans, even if you insert thin cans with the product inlet set to thin cans, if the thin cans are inserted vertically, the product will drop into the vertical stock passage, There was a drawback that it got stuck in. On the other hand, the former product passage (upper end of the vertical stock passage) with a structure that sets the passage width for thin cans or thick cans does not have this drawback, but the product inlet width is always set for thick cans. Therefore, there is a drawback that the product is apt to be mistakenly inserted, and in this case, the product must be removed by putting a hand up to the upper end of the vertical stock passage.

Such a problem can be solved by using a structure having both the function of adjusting the width of the vertical stock passage and the function of adjusting the width of the product inlet. However, in such a structure, it is necessary to set thin cans or thick cans at least at two places in the product storage rack, which complicates the work and may cause one of the settings to be forgotten.

The present invention has been made in view of the above problems, and it is possible to reliably prevent erroneous insertion of a product and clogging of a vertical stock passage, and to separately attach and detach the top plate to and from a product storage rack. Its purpose is to provide a product storage rack of a possible vending machine.

[0009]

In order to achieve the above object, the present invention is directed to a product insertion port for inserting a cylindrical product in a horizontal position, a horizontal stock passage extending obliquely downward from the product insertion port, and a horizontal stock. A vertical stock aisle that extends downward from the tip of the aisle and through a bend, and a merchandise exit formed at the lower end of the vertical stock aisle constitute a horizontal stock aisle and can move forward and backward at the upper end of the vertical stock aisle. In a product storage rack of a vending machine equipped with a top plate that faces the width of the upper end of the vertical stock aisle according to the diameter of the product, the product inlet is the bottom plate at the tail end of the top plate and the bottom plate. It is composed of a closing regulation member that is provided above and parallel to the bottom plate and movable in the vertical direction.The top plate is inserted into and removed from the closing regulation member as the top plate moves back and forth. Face the stationary, characterized in that the engagement portion for regulating a position corresponding poured regulating member to the diameter of the product is provided.

[0010]

[Function] The top plate is allowed to move forwards and backwards to the upper end of the vertical stock passage according to the diameter of the product, and the width of the upper end of the vertical stock passage is adjusted to a wide or narrow width. When the product is loaded in a posture, the loaded product rolls in the horizontal stock passage and is dropped into the vertical stock passage through the bent portion. In this case,
It is composed of a bottom plate at the tail end of the top plate and a closing control member provided above the bottom plate in parallel with the bottom plate and vertically movable. Since the engaging part that regulates the regulating member to the position corresponding to the diameter of the product is provided, the moving position of the closing regulating member is vertically regulated according to the diameter of the product due to the forward and backward movement of the top plate. The width of the product insertion port can be adjusted in correspondence with the diameter of the product by interlocking with the adjustment of the width of the stock passage.

Further, since the mouth width regulation is performed by inserting / removing the engaging portion provided on the top plate into / from the closing regulation member, it is not necessary to have a structure for connecting the top plate and the closing regulation member. The top plate can be detachably attached to the product storage rack.

The product storage rack 1 includes a pair of left and right side plates 4 formed by connecting three steel plates in parallel with each other via a spacer 5, and a plurality of columns 2 are provided in a space defined by both side plates 4. It is designed to be configured. In the product passage 3 that constitutes each column 2, from the product input port 3a side, the input guide 6, the input control pin (the input control member) 7, the top plate 8, the guide plate 9, the car black 10, the outlet control plate 11, and the product. The dispensing device 12 is disposed so as to be supported by the side plates 4, and a pair of left and right interlocking links 13 is disposed on the outer surface of the side plates 4 along with it. The loading guide 6, the loading restriction pin 7, and the front end portion 8a of the top plate 8 mainly serve as a product loading port 3a, the top plate 8 serves as a lateral stock passage 3b, and the guide plate 9 serves as a bent portion 3c. The car black 10 mainly configures the vertical stock passage 3d, and the outlet regulating plate 11 and the product dispensing device 12 mainly configure the product dispensing port 3e.

As shown in FIG. 2 and FIG. 3, the top plate 8 is formed by bending a steel plate into a U-shaped cross section and forming a bottom plate 21.
a and the plate main body 21 that constitutes the compatibility plate 21b,
It is composed of a first support pin 22 at the front end attached to the lower side of the plate body 21, a second support pin 23 at the rear end, and a fulcrum support pin 24 at the middle part. Plate body 21
Is configured so that the product A can be rolled over in a groove formed by the bottom plate 21a and the compatibility plate 21b and can roll in a sideways posture. Also, although not shown, a partition plate can be horizontally moved and adjusted in the groove. The groove width can be adjusted for the products A having different can lengths.

Both ends of the first and second support pins 22 and 23 and the fulcrum support pin 24 are supported by both side plates 4, respectively, and the plate body 21 has these support pins 22 and 2.
It is supported by both side plates 4 via 3, 24. Both ends of the first support pin 22 are movably supported in substantially "V" -shaped first guide grooves 4a formed in the both side plates 4, respectively.
Similarly, both end portions of the second support pin 23 are movably supported by second guide grooves 4b formed in the both side plates 4 and each having a substantially "V" shape. As a result, the plate body 21
Both the first and second guide grooves 2 with the fulcrum support pin 24 as a fulcrum
Guided by 2 and 23, it moves back and forth in the front-back direction while performing a seesaw motion (swing).

That is, as shown in FIG. 2 and FIG.
When the front end of the plate body 21 is grasped and pushed down and pushed forward, the plate body 21 is swung up and down while retreating, and the whole body moves backward with respect to the original position. At the same time, the front part rises slightly and the rear part falls slightly. In reverse order, the plate body 21 is pushed down and pulled toward you to return to the original position. Plate body 2
At the position where 1 is moved backward, the rear end of the plate body 21 faces the upper end of the vertical stock passage 3d to narrow the passage width, and as described later, the front end narrows the vertical width of the product inlet 3a. Then, it becomes a thin can setting for filling the small can. On the other hand, at the position where the plate body 21 has moved forward, the upper end of the vertical stock passage 3d widens and the vertical width of the product insertion port 3a widens, so that a thick can is set for filling a thick can. Therefore, by guiding the plate main body 21 to the first and second guide grooves 22 and 23 and moving it back and forth, it is possible to set the thin can and the thick can.

Further, a pair of left and right hook portions 21c extending rearward are provided at the upper part of the front end of the compatibility plate 21b of the plate body 21, and each hook portion 21c is set in a thin can with respect to the closing regulation pin 7.

It is a product passage 3 having a so-called serpentine structure in which the vertical stock passages 3d are arranged in the upper and lower zigzags, and by letting the load of the product A escape to each curved plate 31,
It is configured so that a large load is not applied to the lowest product A.

Exit control plate 11 and product dispensing device 12
Are arranged below the car black 10 in parallel with each other with a gap forming the product passage 3 therebetween.
The passage width of the product passage 3 is regulated by 1 for thin cans or thick cans, and the lowest product A in the product passage 3 is dispensed one by one by the product dispensing device 12.

The product dispensing device 12 comprises a first weir plate 41 and a second weir plate 42 which are vertically exposed to the product passage 3, and the first weir plate 41 is driven by the internal mechanism based on a sales command. At the same time it is rotated to the stop position overhanging the passage 3,
The second barrier plate 42 is rotated to the restraint release position retracted from the product passage 3. This rotation of the first dam plate 41 prevents the second lowest product A from falling, and also prevents the second dam plate 4 from falling.
The lowest product A is dropped by the rotation of 2, and the product A is paid out (sold). Then, at the next timing, the first dam plate 41 is rotated to the blocking release position, and at the same time, the second dam plate 42 is rotated to the blocking position, so that the second dam plate 4 is rotated.
The product A to be sold next is sent to the position 2.

The outlet regulating plate 11 is vertically supported by the both side plates 4 by upper and lower support pins 51 and 52 provided on the upper and lower sides. Upper support pin 51 and lower support pin 52
Are engaged with a pair of upper and lower guide grooves 4c, 4c of substantially inverted "S" shape formed on both side plates 4, respectively, and are guided by the both guide grooves 4c, 4c to set the thin can setting position and the thick can. Translated to and from the can setting position. That is, the outlet regulating plate 11 is moved between the thin can setting position and the thick can setting position in association with the above-described setting of the thin can and the thick can of the top plate 8, and the product passage 3 including the product dispensing port 3e. The width can be adjusted. This interlocking is performed by an interlocking link 13 provided outside the both side plates 4 and extending parallel to the direction in which the car black 10 continues.

The interlocking link 13 has a thin plate-like shape including an upper end portion 61 formed in a bifurcated shape, a lower end portion 62 bent in an "L" shape, and a long main body 63 connecting the upper and lower end portions 61, 62. The front end of the upper end portion 61 is engaged with the second support pin 23 of the top plate 8, and the lower end portion 62 is engaged with the upper support pin 51 of the outlet regulating plate 11. The interlocking link 13 is a portion of vertically elongated grooves 63a, 63a formed at two positions above and below the middle portion of the main body 63, and the projecting pins 65, 65 of the pair of upper and lower link support members 64, 64 attached to the outer surfaces of the side plates 4 respectively. And is configured to be movable up and down. This vertical movement interlocks the top plate 8 and the outlet regulation plate 11, and in order to ensure this interlocking movement, the front end and the lower end 6 of the upper end 61 of the interlocking link 13 are
The second engaging portions are laterally long grooves 61a and 62a. In addition, the engaging groove 61 is provided at the rear of the upper end 61 of the interlocking link 13.
b is formed, and the interlocking link 13 is also engaged with the guide plate 9 at this portion.

As shown in FIG. 3, the guide plate 9 is
An intermediate product receiving part 71 and “C” on both sides from the product receiving part 71
It is composed of both wing portions 72, 72 extending in a letter shape, and is supported by the side plates 4 by a support shaft 73 attached to the back side of the product receiving portion 71. The guide plate 9 is attached to the support shaft 73 in a freely rotatable state, and the product receiving portion 71 faces diagonally upward and rearward with a desired distance and angle with respect to the rear end 21d of the bottom plate 21a of the top plate 8. It is arranged to do. The product A that has rolled on the top plate 8 collides with the product receiving portion 71 of the guide plate 9, and then is redirected and dropped into the car black 10. In this case, when the product A rolls sideways and in an appropriate posture, the product A is guided to the car black 10 as it is, but when the product A rolls at an angle, the product A is received by the product receiving portion 7.
It is guided to the car black 10 after being corrected to the proper posture by the reaction that collided with 1. Further, when the product A collides with the product receiving portion 71 in a vertically laid posture, the product A is prevented from falling into the car black 10.

That is, the bottom plate 21a of the top plate 8
The product receiving portion 71 of the guide plate 9 with respect to the rear end 21d
By maintaining the appropriate position, the bent portion 3c guides the product A introduced in the proper posture into the car black 10 and the product A introduced in the improper posture becomes the car black 10.
It has a structure that prevents it from falling. In this case, since several types of products A having different can lengths are handled, the above positional relationship is extremely delicate. In this embodiment, the guide plate 9 is linked with the setting of the thin can and the setting of the thick can of the top plate 8. The position of can be moved.

Both ends of the support shaft 73 of the guide plate 9 are formed in the opposite side plates 4 and have a guide groove 4d of an inverted "V" shape.
And is engaged with the engaging groove 61b of the upper end 61 of the interlocking link 13. As a result, due to the vertical movement of the interlocking link 13 accompanying the forward / backward movement of the top plate 8,
The guide plate 9 is guided by the guide groove 4d and moved in a state where the above-mentioned appropriate positional relationship corresponding to the thin can setting and the thick can setting is maintained (see FIG. 3).

On the other hand, the forward / backward movement of the top plate 8 also makes it possible to regulate the upper and lower widths of the product insertion port 3a. As shown in FIG. 4, a closing regulation pin 7 is arranged near the front end portion 8 a of the top plate 8. Input regulation pin 7
Are freely engaged with escape grooves 4e formed in the side plates 4 and extending in the vertical direction. When the closing restriction pin 7 is engaged with the upper end of the escape groove 4e, the opening width (distance) through which the thick can can pass is maintained between the closing restriction pin 7 and the bottom plate 21a of the top plate 8, and the escape groove 4e is held. In the state where the closing regulation pin 7 is engaged with the lower end of, the opening width is maintained between the closing regulation pin 7 and the bottom plate 21a so that only the small can can pass through. That is, when the top plate 8 is moved to the small can setting state, the hook portion 21c of the top plate 8 is hooked on the closing regulation pin 7 and the closing regulation pin 7 is fixed to the lower end of the escape groove 4e, and only the thin can is formed. Can be input (see FIG. 4B). On the other hand, when the top plate 8 is moved to the thick can setting state, the hooking of the hook portion 21c is released, and the closing regulation pin 7 becomes free in the escape groove 4e so that the thick can can be loaded (FIG. 4). (See (a)).

Next, the loading guide 6 will be described with reference to FIGS. 5 and 6. The loading guide 6 is composed of a head portion 82 having shaft portions 81, 81 projecting from both sides and a tail portion 83 extending from the head portion 82 to the top plate 8 side, and is located in front of a substantially extended line of the bottom plate 21 a of the top plate 8. It is arranged. The loading guide 6 is supported by the left and right side plates 4 by the shaft portion 81, and in this state, the tail portion 83 formed in a thin plate shape is arranged so as to ride on the bottom plate 21 a of the top plate 8. Therefore, the space between the front part of the top plate 8 and the side plates 4 is filled, and this part can be filled with the product A (see FIG. 5). Further, as shown in FIG. 1, the head 82 of the loading guide 6 provided in each column 2 is arranged at the front ends of the side plates 4 so as to be vertically aligned.

On the other hand, the shaft portion 81 of the charging guide 6 is formed in a half-moon shape in cross section, and the shaft holes 4 of the side plates 4 for receiving the same are formed.
The f is also formed in a somewhat lacking moon shape. As a result, the loading guide 6 is configured to be rotatable within a predetermined angle range, and when the top plate 8 is moved, the loading guide 6 is appropriately minutely rotated to maintain the state of being placed on the bottom plate 21a ( FIG. 6A). Also, the tail portion 83 of the charging guide 6
Is formed in a bifurcated shape by cutting out the intermediate portion 83a in the plane direction, and when the top plate 8 is moved forward and backward by grasping the front end of the top plate 8, the partition plate in the top plate 8 is switched to the left and right. The loading guide 6 does not get in the way when it is operated (see FIG. 6B).

The interlocking state of the entire product storage rack 1 in the thin can setting and the thick can setting will be described. First,
In the transition from the thick can setting to the thin can setting, when the operator pushes the top plate 8 downward while pushing it in backward, the top plate 8 is moved to the thin can setting position, and at the same time, the hook portion of the top plate 8 is moved. 21c is engaged with the closing regulation pin 7. In addition, the interlocking link 13 is moved downward along with the movement of the top plate 8, and the downward movement moves the guide plate 9 to the thin can setting position and the outlet regulating plate 11 in parallel to the thin can setting position. In this state, the product input port 3a is width-regulated by the input restriction pin 7, the vertical stock passage 3d is width-controlled by the rear end of the top plate 8, and the product delivery port 3e is width-controlled by the outlet restriction plate 11. As a result, only small cans can pass through the product passage 3.

On the other hand, in the transition from the thin can setting to the thick can setting, when the operator presses the top plate 8 downward and pulls it toward the front, the top plate 8 is moved to the thick can setting position, and at the same time, the top plate 8 is moved. The hook portion 21c of No. 8 is pulled out from the closing regulation pin 7. Further, the interlocking link 13 is moved upward with the movement of the top plate 8, the guide plate 9 is moved to the thick can setting position by this movement, and the outlet regulating plate 11 is also moved in parallel to the thick can setting position. In this state, the product passage 3 is widened so that a large can can pass through.

As described above, according to this embodiment, the side plates 4 are provided above the bottom plate 21a of the front end portion 8a of the top plate 8.
Since the closing regulation pin 7 is movably engaged in the up and down direction, and the closing regulation pin 7 is regulated by the engaging portion 21c of the top plate 8 as the top plate 8 moves back and forth. By moving the plate back and forth,
The width of the vertical stock passage 3d and the width of the product insertion port 3a can be adjusted to be wider or narrower at the same time according to the diameter of the product A.
Therefore, the two width restrictions can be performed by one operation, and the two width restrictions can effectively prevent the wrong insertion of the product A and the product jam of the vertical stock passage 3d. Further, since the mouth width regulation is performed by inserting / removing the engaging portion 21c of the top plate 8 into / from the closing regulation pin 7, the top plate 8 can be configured to be detachable from the side plates 4 and the vertical stock passage 3d. The maintenance work and the assembling work of the top plate 8 can be easily performed.

In the present embodiment, the setting of the narrow can at the product inlet is carried out by the hook portion of the top plate being fixed to the lower end of the clearance groove of the closing restriction pin, and the setting of the thick can of the clearance groove of the closing restriction pin is performed. Although it is performed by escaping to the upper end, it is also possible to form the escaping groove further up and down and to provide a step portion on the hook portion so as to regulate only the upper end position where the closing regulation pin escapes. This makes it possible to easily deal with the appearance of various products having different diameters.

[0035]

As described above, according to the product storage rack of the vending machine of the present invention, the position of the insertion regulating member movably provided above the bottom plate at the tail end of the top plate is set to the position of the top plate. Since it is regulated in the vertical direction as it moves forwards and backwards, it is possible to regulate the width of the product inlet in accordance with the diameter of the product by interlocking with the adjustment of the width of the vertical stock passage. These two switching operations can be performed simultaneously, and it is possible to effectively prevent erroneous product insertion and product jamming in the vertical stock passage. In addition, since the mouth width is regulated by inserting / removing the engaging portion provided on the top plate into / from the closing regulation member, the top plate can be configured to be attachable / detachable to / from the product storage rack for maintenance of the product passage. No trouble will occur.
