  The through hole 81 d is a long hole formed in the lever main body 81 a and extending in the left-right width direction of the main body cabinet 10. The size of the through hole 81d in the depth direction is larger than the size of the inclined grooves 71a, 71b, 71c, 71d of the groove 71 in the depth direction.

  Such a lever member 81 is attached to the door body 60 so that the shaft member 61ac is passed through the through-hole 81d so that the lever member 81 is located at a portion where the notch 61aa of the plate member 61a is formed. In a state where the lever member 81 is attached to the door body 60, the distal end side of the lever main body 81 a is located inside the product storage chamber 20, and the proximal end side of the lever main body 81 a is located inside the product storage chamber 40.

  Further, in a state where the door body 60 is attached to the frame member 70, the plate members 61a, 61b, 61c, 61d are developed by the urging force of the coil springs 62a, 62b, 62c, 62d. Moreover, since the vertical size of the product moving port 47 is slightly smaller than the sum of the vertical sizes of the four plate members 61a, 61b, 61c, 61d constituting the door body 60, the lever body 81a is in contact with the lower part of the notch 71x of the frame member 70, and the front and back surfaces of the plate members 61a, 61b, 61c, 61d are slightly inclined with respect to the vertical direction. , 61c, 61d close the product moving port 47. Furthermore, one end and the other end of the coil spring 62a abut on the surface of the plate members 61a and 61b, one end and the other end of the coil spring 62b abut on the back surface of the plate members 61b and 61c, and one end and the other end of the coil spring 62c are the plate members. Since the surfaces abutting on the surfaces of 61c and 61d and the coil springs 62a, 62b and 62c abutting are changed in order from the upper side to the lower side, the plate member 61a has a rear surface as shown in FIG. The plate member 61b is slightly inclined with respect to the vertical direction in such a manner that the side faces upward and the front side faces downward, and the plate member 61b is slightly in the vertical direction in such a manner that the front side faces upward and the back side faces downward. The plate member 61c is slightly inclined with respect to the vertical direction in such a manner that the back side faces upward and the front side faces downward, and the plate member 61d The product moving port 47 is closed in a state where the back surface side is slightly inclined with respect to the vertical direction, in other words, the plate members 61a, 61b, 61c, 61d are alternately inclined. Become.

  Next, the operation of the first product delivery device 82 will be described. When the first refill bucket 21d moves in the front area of the product column 31 of the product storage room 20, in other words, when the first refill bucket 21d does not move toward the product moving port 47, the first refill bucket 21d The contact member does not come into contact with the lever member 81 of the door body 60, and the plate members 61 a, 61 b, 61 c, 61 d are maintained in the unfolded state by the urging force of the coil springs 62 a, 62 b, 62 c, 62 d, and the door body 60. The product moving port 47 is closed.

  On the other hand, when the upper first replenishing bucket 21d moves downward toward the product moving port 47, the contact member of the first replenishing bucket 21d abuts on the lever member 81 of the door body 60 by the movement.

  Further, when the first refill bucket 21d moves downward, the engagement pins 81b and 81c of the lever member 81 move downward along the engagement groove 76 along with the movement, and the shaft members 61ac and 61be move to the groove. It moves from 71 to below along 71. When the shaft members 61ac, 61be move downward, the plate members 61a, 61b, 61c, 61d are gradually folded against the urging force of the coil springs 62a, 62b, 62c, 62d. When the shaft member 61ac moves along the groove 71, since the inclined grooves 71a, 71b, 71c, 71d are inclined with respect to the vertical direction, the shaft member 61ac moves in the front-rear direction of the vending machine. However, the shaft member 61ac moves in the through hole 81d of the lever member 81.

  Thereafter, when the first replenishing bucket 21d moves to a position facing the commodity moving port 47 by further downward movement of the first replenishing bucket 21d, as shown in FIGS. The plate members 61a, 61b, 61c, and 61d that are in the position are displaced to the folded state. When the plate members 61a, 61b, 61c, 61d are displaced in the folded state, the front surface of the plate member 61a and the back surface of the plate member 61b face each other, the front surface of the plate member 61b and the back surface of the plate member 61c face each other, and the plate member The front surface of 61c and the back surface of the plate member 61d face each other, and the product moving port 47 is opened.

  Thereafter, when the first replenishing bucket 21d moves upward so as to be separated from the rear area of the product moving port 47, the product moving port 47 is closed by the door body 60 by the urging force of the coil springs 62a, 62b, 62c, 62d.

  Further, inside the product storage chamber 40, the above-described sales conveyance unit 52, a door body (not shown) that opens and closes the product carry-out port 46, and a coil spring (not shown) that is always urged to close the product carry-out port 46 are attached. 2), and a second product delivery device (product delivery device) 89 shown in FIG. 2 is provided. In addition, since the door body, coil spring, and door opening means of the second product delivery device 89 have the same configuration as the first product delivery device 82 described above, description thereof will be omitted.

  In the vending machine configured as described above, the product C stored in the product storage chamber 40 is maintained at a desired temperature state by driving the cooling unit or the heating unit in the sales standby state.

  In this standby state, if the deposit information by inserting the bill through the bill insertion slot 13 or by inserting the coin through the coin insertion slot 12 and the selection information of the product C through the selection switch satisfy the predetermined sales conditions, When the transport unit 52 is driven, the sales bucket 52d is disposed to face the product column 31 containing the selected product C. In the product column 31 in which the sales bucket 52d is opposed, only one product C is delivered to the sales bucket 52d by driving the bend mech. The sales bucket 52 d to which the product C has been delivered moves to a position facing the product carry-out port 46 by driving the sales conveyance unit 52. If the product takeout door is opened in this state, the product C arranged in the sales bucket 52d can be taken out to the outside.

  On the other hand, when the sale of the product C ends, the first replenishment transport unit 21 is driven at an appropriate timing, so that the first replenishment bucket 21d faces the product column 31 containing the same product C as the sold product C. Be placed. In the product column 31 in which the first replenishing bucket 21d is disposed oppositely, only one product C is delivered to the first replenishing bucket 21d by driving the bend mech. The first replenishing bucket 21 d to which the product C has been delivered moves to a position facing the product moving port 47 by driving the first replenishing transport unit 21.

  Further, when the second replenishment transport unit 51 is driven in synchronization with the driving of the first replenishment transport unit 21, the second replenishment bucket 51 d is moved to a position facing the product moving port 47. In this state, when a conveyor (not shown) provided in the first replenishing bucket 21 d is driven, the product C moves from the product storage chamber 20 to the product storage chamber 40 through the product transfer port 47. Thereafter, by driving the second replenishment transport unit 51, the second replenishment bucket 51d is disposed opposite to the commodity column 31 that has previously sold the commodity C. In this state, the product C stored in the second refill bucket 51d is refilled in the product column 31 by driving a conveyor (not shown) provided in the second refill bucket 51d.

  Thereafter, the above-described operation is repeatedly performed to store the product C maintained at a desired temperature state in the product storage chamber 40, and the product C stored in the product storage chamber 20 is sequentially replenished to the product storage chamber 40. It will be. In such a vending machine, since the product C stored first is sold first, there is no possibility of storing the product C sold in a heated state for a long time. In addition, the products C can be sold in the total number of the products C stored in the product storage chamber 20 and the products C stored in the product storage chamber 40, but only the products C stored in the product storage chamber 40 are temperature controlled. Therefore, it is possible to save energy compared to a vending machine that controls the temperature inside the main body cabinet 10.

  According to the product delivery devices 82 and 89 according to the present invention, when the buckets 21d and 52d are moved to a position facing the product moving port 47 or the product carry-out port 46, the coil springs are attached by the movement of the buckets 21d and 52d. Since the door opening means for opening the door body against the force is provided, the product moving port 47 or the product carry-out port 46 can be opened by using the force by which the buckets 21d and 52d move to the opposing positions. Therefore, it is not necessary to open the product moving port 47 or the product carry-out port 46 by bringing the product C into contact. Accordingly, it is possible to prevent the product posture from being lost due to the product C being brought into contact with the flapper, and to prevent the possibility of product clogging.

  Furthermore, according to the product delivery devices 82 and 89 according to the present invention, the vertical and horizontal sizes of the plate members 61a, 61b, 61c and 61d are set smaller than the vertical and horizontal sizes of the bottom surface of the first refill bucket 21d. Therefore, the door body is folded on the moving area of the first refill bucket 21d. Therefore, it is not necessary to secure a space for opening the door in the main body cabinet 10, and a small vending machine can be provided.

  In addition, since the product moving port 47 is closed in such a manner that the inclined states of the plate members 61a, 61b, 61c, 61d are alternate, each plate member 61a, 61b, 61c, 61d Since it is in a slightly inclined state, it can be prevented that the upper and lower end portions of the plate members 61a, 61b, 61c, 61d that are opposed to each other are caught when they are shifted from the unfolded state to the folded state described later. . As is clear from the above-described embodiment, the product delivery device in the present invention refers to the one chamber (the product storage chamber 20) partitioned from the heat insulation to the other chamber (the product storage chamber 40) or the product outlet 19. Form in which the product C is sent out through an opening (product moving port 47) formed in the heat insulating partition wall (the back wall member 43) that defines the one room, or one chamber (product containing chamber 40) that is insulated. A product C is sent from one to another chamber (product storage chamber 20) through an opening (product outlet 46) formed in a heat insulating partition wall (inner door 41) defining the one room. is there.

  In the above-described embodiment, the door body is constituted by a plurality of plate members 61a, 61b, 61c, 61d. However, the present invention is not limited to this, and the door body is composed of a single plate member 61a, 61b, 61c, 61d, and slides with respect to the back wall member 43 or the inner door 41 to thereby move the product moving port 47 or the like. You may comprise so that the goods exit 46 may be opened and closed.

  However, when the door body is configured to slide relative to the back wall member 43 and the inner door 41 as described above, the door body 60 is attached to the back wall member 43 in order to ensure the airtightness of the product storage chamber 40. And the door body needs to be in contact with the inner door 41. Thus, when the door body 60 is brought into contact with the back wall member 43 and the door body is brought into contact with the inner door 41, the door body rubs when opening and closing, and the thickness of the door body gradually decreases. There is a risk that it may be difficult to ensure the airtightness of the product storage chamber 40. On the other hand, if the door body is configured to be displaceable between the expanded state and the folded state as described above, the door body is not rubbed with opening and closing. Therefore, even when it is used for a long time, the airtightness of the product storage chamber 40 can be ensured.

  Further, in the above-described embodiment, the description has been given of the case where the closed product moving port 47 or the product outlet 46 is opened when the buckets 21d and 52d move from the upper side toward the lower side. However, the moving direction of the buckets 21d and 51d is not limited to this and can be set arbitrarily.

  Furthermore, in embodiment mentioned above, although the example which has arrange | positioned the goods storage chamber 20 and the goods storage chamber 40 in the front-back direction in the store | warehouse | chamber of the main body cabinet 10 is shown, it does not restrict to this, For example, The product storage room 20 and the product storage room 40 can also be applied to a structure in which the main body cabinet 10 is disposed in the left-right direction.

  Moreover, in embodiment mentioned above, although the example which has a vent mech in the edge part of each product column 31 of the product rack 30 is shown. For example, the product column 31 is provided with a payout mechanism that is conductively connected to a drive mechanism provided in the buckets 21d and 52d to individually pay out the products, and the buckets 21d and 52d are provided in the designated product column 31. When it moves, the thing which pays out goods C by driving the discharge mechanism of goods column 31 with the drive mechanism of the buckets 21d and 51d concerned can be used.

  Further, in the above-described embodiment, an example is shown in which the conveyors are attached to the buckets 21d and 52d. However, the present invention is not limited to this. For example, the bottom surfaces of the buckets 21d and 51d are inclined in the same manner as the product rack 30. The product C received in the buckets 21d and 51d may be slid by its own weight. In this case, a stopper for the product C received in the buckets 21d and 51d is provided, and driving means for opening and closing the stopper is built in the buckets 21d and 51d.
