The length X1 of the shaft end portion 221a of the first shaft portion 221 is formed to be longer than the length X2 of the shaft end portion 221b of the first shaft portion 221. The second shaft portion 231 has a shaft end portion 231a protruding outward from the second shaft portion 231 and a shaft protruding inward from the support portion 23 in a manner extending to a notch in the central portion of the support portions 22 and 23. It has an end 231b. The length of the shaft end portion 231a is formed longer than the length of the shaft end portion 231b, but it may be the same. In FIG. 5 (c), "X3" is the length of the width of the support portion 22, and "X4" is the length between the end of the shaft end portion 221a and the end of the shaft end portion 221b, "X5". Is the length from the outer edge of the support portion 22 (the base end portion of the shaft end portion 221a) to the end of the shaft end portion 231a of the support portion 23, and "X0" is the end portion of the shaft end portion 221a of the support portion 22. It is the length between the support portion 23 and the end portion of the shaft end portion 231a in the support portion 23. These lengths are determined by the relationship between the first bearing portion 1031 and the second bearing portion 1032 formed at the lower end of the bearing forming portion 103 of the rack fixing bracket 10 described later. This relationship will be described later.

A torsion coil spring 30 is arranged in the notch at the center of the support portions 22 and 23 of the flapper 20. The torsion coil spring 30 is arranged between the shaft end portion 221b of the first shaft portion 221 and the shaft end portion 231b of the second shaft portion 231 in a compressed state, and the left and right ends thereof are the shafts of the first shaft portion 221. The shaft end portion 221b of the first shaft portion 221 and the shaft end portion 231b of the second shaft portion 231 are released by releasing the compressed state after facing the tip of the end portion 221b and the tip of the shaft end portion 231b of the second shaft portion 231. It is supported by.

In order to swingably support the flapper 20, as shown in FIG. 6, the first bearing portion 1031 and the second bearing portion 1032 are formed by bending the lower end of the bearing forming portion 103 of the rack fixing bracket 10 into a cylindrical shape. And are formed. The first bearing portion 1031 is composed of a left and right bearing portion 1031a on the right side in front view (in the case of FIG. 6, the bearing portion on the left side) and a bearing portion 1031b on the left side in front view (in the case of FIG. 6, the bearing portion on the right side). .. The bearing portion 1031a of the first bearing portion 1031 supports the shaft end portion 221a of the first shaft portion 221 of the flapper 20, and the bearing portion 1031b of the first bearing portion 1031 is the shaft of the first shaft portion 221 of the flapper 20. It supports the end 221b. The second bearing portion 1032 supports the shaft end portion 231b of the second shaft portion 231 of the flapper 20. The right side bearing part 1031a, the left side bearing part 1031b, and the second bearing part 1032 constituting the first bearing part 1031 are formed so as to have the same axial center. In FIG. 6, “Y1” is the distance (length) between the bearing portion 1031a and the bearing portion 1031b of the first bearing portion 1031, and “Y2” is the bearing portion 1031b and the second bearing portion in the first bearing portion 1031. The distance (length) between 1032 and "Y3" is the distance (length) between the bearing portion 1031a and the second bearing portion 1032 of the first bearing portion 1031, and "Y4" is the distance (length) between the first bearing portion 1031 and the first bearing portion 1031. The distance (length) between the bearing portions 1031b.

Here, the first bearing portion 1031 formed at the lower end of the bearing forming portion 103 of the rack fixing bracket 10 and the first shaft portion 221 of the flapper 20 are defined to have the following relationship. That is, the distance between the bearing portion 1031a and the bearing portion 1031b of the first bearing portion 1031 (length Y1) and the width of the support portion 22 of the flapper 20 (length X3: see (c) in FIG. 5) are different. The relationship between the length (X3 + X2) of the shaft end portion 221b of the shaft portion 221 plus the length X2 and the length X4 between the end portion of the shaft end portion 221a and the end portion of the shaft end portion 221b is as follows. It is set so that (X3 + X2) <Y1 <X4 ". Further, the relationship between the distance (length Y4) between the bearing portions 1031b of the first bearing portion 1031 and the length X2 of the shaft end portion 221b of the first shaft portion 221 is determined to be "Y4 <X2". Has been done. Regarding the relationship between the first bearing portion 1031 and the second bearing portion 1032 of the rack fixing bracket 10 and the first shaft portion 221 and the second shaft portion 231 of the flapper 20, the bearing portions 1031a and the first bearing portion 1031 in the first bearing portion 1031 2 The distance between the bearing portion 1032 (length Y3) and the length from the outer edge of the support portion 22 in the flapper 20 (the base end portion of the shaft end portion 221a) to the end of the shaft end portion 231a in the support portion 23. The relationship between X5 and the length X0 between the end of the shaft end 221a of the support portion 22 and the end of the shaft end 231a of the support portion 23 is determined to be "X5 <Y3 <X0". Has been done. The distance (length Y2) between the bearing portion 1031b and the second bearing portion 1032 in the first bearing portion 1031 is the support portion 23 of the flapper 20 and the shaft end portion 221b and the second shaft of the first shaft portion 221. The torsion coil spring 30 supported by the shaft end portion 231b of the portion 231 can be received and has a length slightly larger than that of the torsion coil spring 30.

Next, the procedure for attaching the flapper 20 to the rack fixing bracket 10 will be described with reference to FIG.

First, the flapper 20 is attached to the rack fixing bracket 10. At this time, the twist coil spring 30 is not attached to the flapper 20. The first shaft portion 221 and the second shaft portion 231 of the flapper 20 are brought closer to the first bearing portion 1031 and the second bearing portion 1032 of the rack fixing bracket 10 from below the bearing forming portion 103 of the rack fixing bracket 10. Then, the flapper 20 is tilted so that the shaft end portion 221a side of the first shaft portion 221 of the flapper 20 is high and the shaft end portion 231a side of the second shaft portion 231 is low. After slightly shifting the flapper 20 to the left in this state, the shaft end portion 221a of the first shaft portion 221 is inserted into the bearing portion 1031a of the first bearing portion 1031 of the rack fixing bracket 10. At this time, the axial center of the shaft end portion 221a is tilted with respect to the axial center of the bearing portion 1031a, but since the width of the bearing portion 1031a is narrowed, the shaft end portion 221a can be inserted into the bearing portion 1031a. can. After inserting the shaft end portion 221a into the bearing portion 1031a (that is, inserting it into the bearing portion 1031a to the base end of the shaft end portion 221a) until the outer edge of the support portion 22 abuts on the bearing portion 1031a, the inclination of the flapper 20 is returned. .. In this case, due to the relationship of "(X3 + X2) <Y1" and "X5 <Y3" described above, even if the inclination of the flapper 20 is returned, the shaft end portion 221b and the second shaft portion 231 of the first shaft portion 221 of the flapper 20 The shaft end portion 231b does not interfere with the first bearing portion 1031 (bearing portion 1031b) and the second bearing portion 1032 of the rack fixing bracket 10, respectively. In this way, after returning the tilt of the flapper 20, the flapper 20 is slid to the left to move the shaft end portion 221b of the first shaft portion 221 of the flapper 20 and the shaft end portion 231b of the second shaft portion 231, respectively. It is inserted into the first bearing portion 1031 (bearing portion 1031b) and the second bearing portion 1032 of the rack fixing bracket 10. Then, due to the relationship of "Y3 <X0" described above, the flapper 20 has the first shaft portion 221 and the second shaft portion 231 swingably supported by the first bearing portion 1031 and the second bearing portion 1032 of the rack fixing bracket 10. Will be done.

Next, the torsion coil spring 30 is mounted between the support portions 22 and 23 of the flapper 20 that is oscillatingly supported by the rack fixing bracket 10. First, one arm 31 side of the torsion coil spring 30 is inserted into the shaft end portion 221b of the first shaft portion 221 of the flapper 20. At this time, the twist coil spring 30 is twisted so that the other arm portion 32 abuts on the back surface of the abutting portion 21 of the flapper 20 and one arm portion 31 abuts on the lower end of the bearing forming portion 103 of the rack fixing bracket 10. It gives urging power. Subsequently, when one arm 31 side of the torsion coil spring 30 is deeply inserted into the shaft end portion 221b of the first shaft portion 221 of the flapper 20, one arm 31 of the torsion coil spring 30 becomes a bearing forming portion of the rack fixing bracket 10. The lower end of the 103 is slid to engage with the locking groove 1030 provided in the bearing forming portion 103. Next, the torsion coil spring 30 is compressed so that the other arm portion 32 side of the torsion coil spring 30 faces the shaft end portion 231a of the second shaft portion 231 in the flapper 20. In this state, the compression of the torsion coil spring 30 is released so that the other arm portion 32 side is inserted into the shaft end portion 231a.

In this way, the arm 31 is locked to the rack fixing bracket 10 and the arm 32 is locked to the back surface of the contact portion 21 of the flapper 20 so as to be mounted between the support portions 22 and 23 of the flapper 20. The twisted coil spring 30 gives the flapper 20 an urging force in the direction of projecting into the product drop passage. Further, the torsion coil spring 30 mounted between the support portions 22 and 23 of the flapper 20 is slightly larger than the bearing portion 1031b of the first bearing portion 1031 of the rack fixing bracket 10 and the eaves portion 1033 of the second bearing portion 1032. Since the length is set to be small, the flapper 20 is prevented from moving to the left in FIG. 6 in a manner opposite to the procedure for attaching the flapper 20 to the rack fixing bracket 10. Therefore, the flapper 20 is maintained in a state in which the flapper 20 is oscillatingly supported by the first bearing portion 1031 and the second bearing portion 1032 of the rack fixing bracket 10, so that the flapper 20 does not fall off from the rack fixing bracket 10. In the flapper 20 to which the urging force in the direction of projecting into the product fall passage is applied by the torsion coil spring 30, the support portions 22 and 23 of the flapper 20 are provided on the left and right ends of the bearing forming portion 103 of the rack fixing bracket 10. By abutting against the eaves portion 1033, the protruding posture to the product falling passage is restricted, and the rack fixing bracket 10 is maintained in a standby state in a slightly downward posture with respect to the horizontally long main body 101.

Next, FIG. 7 shows a protective member 70 for horizontally mounting the rack fixing bracket 10 on the front surfaces of the respective product storage chambers 12, 13, and 14. FIG. 7A is a perspective view of the heat insulating partition plate 11 to which the protective member 70 is attached as viewed diagonally from above, and FIG. 7B is a perspective view of the metal protective member 70 attached to the heat insulating partition plate 11. It is a figure.

The heat insulating partition plate 11 divides the inside of the product storage compartment into a plurality of product storage chambers 12, 13, 14 (see FIG. 1) in the left-right direction, and is a base material 110 made of urethane foam (heat insulating board) as a heat insulating material. And the upper and lower reinforcing members 111 made of sheet metal attached to the upper end and the lower end to reinforce the base material 110, the gasket 113 attached to the front surface of the base material 110, and the lower portion of the base material 110. It is composed of a protective member 70 made of sheet metal that covers the area. The gasket 113 abuts on the inner wall of the heat insulating inner door 3 that closes the product storage of the main body cabinet 1 and prevents heat leakage between the product storage chambers partitioned to the left and right by the heat insulating partition plate 11. Cushions C are attached to the upper end, lower end, and rear end of the heat insulating partition plate 11.

The sheet metal protective member 70 that covers the lower region of the base material 110 is a product when the product unloading shooter 5, the cooling / heating unit 6 is attached, or when the product unloading shooter 5, the cooling / heating unit 6 is attached / detached during maintenance and inspection. This is to prevent the carry-out shooter 5 and the cooling / heating unit 6 from colliding with the base material 110 of the heat insulating partition plate 11 and being damaged. The protective member 70 is fixed by screwing the lower side to the lower reinforcing member 112, while the upper side of the protective member 70 is attached to the base material 110 with double-sided tape.

Three rows of wiring covers 71 are formed on the protective member 70 by cutting and raising. The wiring cover 71 sandwiches (holds) the wiring of the electrical components (solenoid, motor, sold-out switch, etc.) mounted on the product unloading devices 45, 45 arranged back to back in the product storage rack 4 to provide a heat insulating partition. It guides along the plate 11. The wiring of the electrical components mounted on the product unloading devices 45 and 45 is the wall surface on the left side of the front view of each of the product storage chambers 12 to 14 by the wiring guide 450 (see FIG. 4) attached to the lower part of the product unloading devices 45 and 45. (In the case of the heat insulating partition plate 11 in FIG. 7, it is pulled out to the side surface on the right side in the front view) and hangs down. There is a risk of contact and disturbing the posture of the product. Therefore, the wiring cover 71 has a function of sandwiching (holding) the wiring and guiding the wiring along the heat insulating partition plate 11. The wiring cover 71 is formed by bending so that the front edge side rises from the protective member 70 toward the product storage chamber and the free end extends in the depth direction to open the space between the wiring cover 71 and the wiring cover 71. The wiring cover 71 is formed so that its free end approaches the surface of the protective member 70 toward the back, that is, the gap between the wiring cover 71 and the surface of the protective member 70 narrows toward the back. There is. Further, the peripheral edge of the wiring cover 71 is deburred to prevent the wiring from being damaged.

The work of passing the wiring of the electrical components mounted on the product unloading devices 45, 45 through the wiring cover 71 is performed by locating the wiring on the back side of the wiring cover 71 and then moving the wiring to the front side along the surface of the protective member 70. It is moved so that it slips into the inside of the wiring cover 71 from the open end of the wiring cover 71. In this case, since the gap at the open end of the wiring cover 71 is narrowed, the wiring comes into contact with the free end when the wiring is slipped into the inside of the wiring cover 71. However, since the wiring cover 71 has flexibility, when the wiring is moved to the front side, the free end of the wiring cover 71 bends so as to expand, and the wiring slips into the inside of the wiring cover 71. When passing the wiring through the wiring cover 71, the free end of the wiring cover 71 can be opened by hand to pass the wiring.

At the front end of the protective member 70, a locking member 72 for locking the left engaging piece 104 of the left and right engaging pieces 104, 104 of the rack fixing bracket 10 is provided. The locking member 72 has upper and lower legs 721 and 722, and has a bridge shape integrally formed with the protective member 70 in such a manner that a through hole 720 is formed between the locking member 72 and the plate surface of the protective member 70. .. The through hole 720 is formed in a size that allows the hook 104a of the engagement piece 104 on the left side of the rack fixing bracket 10 to penetrate. In the notch 730 formed on the rear side of the locking member 72, the trailing edge 730a facing the through hole 720 is recessed on the back side in FIG. 7. When the trailing edge 730a of the notch 730 and the protective member 70 on the rear side of the through hole 720 are flush with each other, the hook 104a is inserted when the hook 104a of the engaging piece 104 is inserted into the through hole 720 of the locking member 72. This is because the trailing edge may come into contact with the trailing edge 730a of the protective member 70 and hinder the passage of the hook 104a. Therefore, by denting the trailing edge 730a facing the through hole 720 toward the back side in FIG. 7 with respect to the protective member 70, the hook 104a of the engaging piece 104 of the rack fixing bracket 10 is engaged with the through hole 720 of the locking member 72. Since there is no possibility that the trailing edge of the hook 104a interferes with the trailing edge 730a of the protective member 70 when the hook 104a is inserted into the through hole 720, the hook 104a can be smoothly inserted into the through hole 720.

The protective member 70'is also provided on the side surface (the side surface on the left side when viewed from the front) on the side opposite to the drawing of the heat insulating partition plate 11 in FIG. In this case, the protective member 70'provides the locking member 72, while the wiring cover 71 is not provided. Further, a protective member 70'is also provided on the right side wall 1c of the main body cabinet, and a protective member 70 is provided on the left side wall 1c of the main body cabinet.

The rack fixing bracket 10 is attached to the through holes 720 of the locking members 72, 72 in which the hooks 104a, 104a of the left and right engaging pieces 104, 104 of the rack fixing bracket 10 are provided on the left and right protective members 70, 70'. Insert it into 720 and let it penetrate. In this state, the main body 101 of the rack fixing bracket 10 is located below the fixing member 47 without overlapping in the front-rear direction with the fixing member 47 provided on the front surface side of the lower end portion of the product storage rack 4. After that, when the rack fixing bracket 10 is slid upward, the left and right hooks 104a and 104a overlap with the upper legs 721 and 721 of the left and right locking members 72 and 72 in the front-rear direction, and the left and right hooks of the rack fixing bracket 10 are engaged. The pieces 104, 104 are locked to the locking members 72, 72. This state is shown in FIG. In FIG. 8, the product storage rack 4 is omitted in order to make it easier to understand the relationship between the locking member 72 provided on the protective member 70 and the engaging piece 104 of the rack fixing bracket 10.

As described above, the main body 101 of the rack fixing bracket 10 is a product storage rack in a state where the rack fixing bracket 10 is slid upward and the left and right engaging pieces 104, 104 are locked to the locking members 72, 72. Screw insertion holes 101a, 101a formed on the plate surface of the main body 101, which overlap with the fixing member 47 provided on the front surface side of the lower end portion of 4, are screw holes 472a provided in the screw threaded portion 472 of the fixing member 47. The screw S is screwed into the screw hole 472a of the fixing member 47 through the screw insertion holes 101a and 101a of the main body 101 to fasten the two. In this case, since the screw insertion holes 101a and 101a are formed as elongated holes extending in the vertical direction, the mounting error and the dimensional error of the product storage rack 4 suspended and supported in the product storage are absorbed. The rack fixing bracket 10 and the fixing member 47 can be securely fastened with screws S.

The flapper 20 swingably supported by the rack fixing bracket 10 horizontally laid across the front surfaces of the respective product storage chambers 12, 13 and 14 is the product storage passage in the front row of the product storage rack 4. It protrudes into the product drop passage below the product unloading device 45 arranged at the lower end exit of the 43. Then, when the product is unloaded from the product unloading device 45 arranged at the lower end exit of the product storage passage 43 in the front row, the flapper 20 swings in the direction of retracting from the product drop aisle due to the weight of the product. In such a swinging process, the flapper 20 reduces the falling speed of the product. Further, due to the above-mentioned rocking operation, the flapper 20 lands at a position slightly rearward of the position where the product lands on the product unloading chute 5 when the flapper 20 does not exist. As a result, the drop impact when the product lands on the product carry-out chute 5 is alleviated, and the forming when the product is a carbonated drink is suppressed.

Here, as shown in FIG. 3, the product storage rack 4 provided with a plurality of rows of product storage passages 43 in the front-rear direction is the product unloading device 45 of the product storage passage 43 on the front stage side according to the inclination angle of the product unloading shooter 5. Is gradually configured so as to be located below the product unloading device 45 of the product storage passage 43 on the rear stage side, so that the distance from the product unloading device 45 of the product storage passage 43 on the front stage side to the product unloading shooter 5 is shortened. It has been devised. However, the distance from the product unloading device 45 of the product storage passage 43 in the front row to the product unloading shooter 5 is longer than the distance from the product unloading device 45 of the product storage passage 43 on the rear stage side to the product unloading chute 5. Is normal. Therefore, the flapper 20 swingably supported by the rack fixing bracket 10 horizontally laid across the front surfaces of the respective product storage chambers 12, 13 and 14, is the product storage passage 43 in the front row of the product storage rack 4. It works effectively to alleviate the drop impact when the product carried out from the product carrying-out device 45 arranged at the lower end exit of the product lands on the product carrying-out shooter 5.

Further, in order to bring the products carried out from the product storage racks 4 to the respective product carry-out outlets, the products carried out from the product storage racks 4 are brought closer to the front of the product carry-out chute 5 of the left and right product storage chambers 12 and 14 in which a plurality of product storage racks 4 are stored and installed. As described in the explanation of FIG. 1, the inclined auxiliary chute plate 5b is provided. In the case shown in FIG. 1, the auxiliary chute plate 5b of the product unloading shooter 5 arranged in the product storage chamber 14 is used to store products on the front side of the outer product storage rack 4 of the two left and right product storage racks 4 and 4. It is located directly below the passage 43. In particular, in the product storage aisle 43 in the front row of the outer product storage rack 4 of the two left and right product storage racks 4 and 4, the auxiliary chute plate 5b exists directly below the product storage passage 43. Therefore, when the flapper 20 is not provided, the products carried out from the product unloading device 45 in the product storage passage 43 in the front row of the outer product storage rack 4 will land on the inclined auxiliary chute plate 5b. Become. In this case, since the auxiliary chute plate 5b is inclined so as to gradually increase the inclination angle toward the outside, when the product in the sideways posture lands on the auxiliary chute plate 5b, one end side of the sideways posture (one end facing outward). The side) first lands on the auxiliary chute plate 5b, and then the other end side (one end side facing inward) of the sideways posture lands on the auxiliary chute plate 5b. Then, a rotational force is applied to the product landing on the auxiliary chute plate 5b so as to change from the sideways posture to the standing posture, and the product landing on the auxiliary chute plate 5b changes from the sideways posture to the standing posture. When the product in the standing posture reaches the product carry-out outlet in this way, the product may be clogged with the carry-out door 31. This is because the product unloading door 31 is pivotally supported on the upper end side and pushed open by the product (own weight). Therefore, in the case of a product in a sideways posture, the product hits the lower side of the product unloading door 31. Since the product delivery door 31 is in contact with the product, the product carry-out door 31 can be easily opened. On the other hand, when the upper end side of the standing product comes into contact with the upper side (shaft support side) of the product carry-out door 31, the distance from the contact point to the shaft support point is short. The carry-out door 31 may not open and the product may be jammed. On the other hand, when the flapper 20 is provided, the product carried out from the product unloading device 45 by the flapper 20 is landed at a position rearward from directly below the product storage passage 43 in the front row of the outer product storage rack 4. Therefore, the product lands on the auxiliary chute plate 5b and the product unloading shooter 5. In this way, when the product lands across the auxiliary chute plate 5b and the product unloading shooter 5, the inclination angle when the product lands becomes smaller, so that the rotational force that changes from the sideways posture where the product acts to the standing posture is generated. The product is not suppressed and stands up. Therefore, by providing the flapper 20, when the product carried out from the product carrying-out device 45 lands on the product carrying-out chute 5, it is possible to prevent the product from being laid down and standing upright to cause product clogging.

Note that FIG. 7 has described a case in which locking members 72 and 72 for locking the left and right engaging pieces 104 and 104 of the rack fixing bracket 10 are integrally provided on the protective member 70, but as shown in FIG. , The locking member 72 may be separated from the protective member 70. That is, FIG. 9 shows a modified example of the locking member 72 that locks the left and right engaging pieces 104, 104 of the rack fixing bracket 10, and in FIG. 9, the same members as those in FIG. 7 are designated by the same reference numerals. I will omit duplicate explanations.

In FIG. 9, the sheet metal protective member 70 is shown again, and the protective member 70 is formed with three rows of wiring covers 71 by cutting and raising. Here, reference numeral 74 shown in FIG. 9 is a locking metal fitting provided with a locking member 72 for locking the left engaging piece 104 of the left and right engaging pieces 104, 104 of the rack fixing metal fitting 10. .. The locking metal fitting 74 is made of a rectangular flat plate-shaped sheet metal, and a locking member 72 is provided on the front side of the locking metal fitting 74. The locking member 72 has upper and lower legs 721 and 722, and forms a bridge shape integrally formed with the locking metal fitting 74 in a manner of forming a through hole 720 between the locking member 72 and the plate surface of the locking metal fitting 74. There is. The through hole 720 is formed in a size that allows the hook 104a of the engagement piece 104 on the left side of the rack fixing bracket 10 to penetrate. The locking metal fitting 74 is fixed to the protective member 70 by welding. According to the modified example shown in FIG. 9, the locking member 72 is formed on the locking metal fitting 74 and fixed to the protective member 70, so that the length of the protective member 70 in the front-rear direction is shortened and the material cost is reduced. It becomes possible to do.

As described above, according to the vending machine of this embodiment, the main body cabinet 1 formed of a heat insulating housing having an open front surface and the product storage chambers of the main body cabinet 1 are arranged in a plurality of product storage chambers 12 in the left-right direction. A heat insulating partition plate 11 divided into 13 and 14, a product storage rack 4 suspended and supported in the product storage and a fixing member 47 provided on the front side of the lower end portion, and the product storage rack 4.
