  When the product A is thrown in the state where the product A is not stored on the inclined shelf 25, when the product A moves to the rear side due to the inclination of the inclined shelf 25, the up-and-down regulating plate 71 is pushed up and passes through. Even if the product A is slanted depending on the manner, the product A can be correctly aligned because it can be corrected to be parallel to the vertical regulation plate 71 when passing through the vertical regulation plate 71.

  In addition, as shown in FIG. 2, when the product is paid out, the solenoid 49 of the drive mechanism 43 is excited, and the first drive pin 54 and the second drive pin 55 are moved from the rear first position to the front second position. Move to.

  By moving the first drive pin 54 to the second front position, the first stopper 41 is allowed to rotate, so that the weight of the sale product A1 moves backward on the inclined shelf 25. Start and tilt the first stopper 41 backward. At this time, the initial movement energy of the sales product A1 is small, and the first stopper 41 is inclined forward and urged forward by the first spring 45. Although it is assumed that the first stopper 41 cannot be smoothly moved backward, the forward path of the guide groove 61 in the process in which the first drive pin 54 moves from the first rear position toward the second front position. It moves along the side movement path 62 (path indicated by a one-dot chain line in FIG. 5), and the first drive pin 54 comes into contact with the second cam portion 59 to forcibly move the first stopper 41 backward. Since it is rotated, the rearward movement of the sales commodity A1 can be started smoothly, and the first stopper 41 can be smoothly tilted backward.

  The first stopper 41, which is pushed by the sale product A <b> 1 and falls backward, enters the product fall passage 20 and rotates downward in the product fall passage 20 to reach a substantially horizontal position in the product fall passage 20. At the time of rotation, the first stopper 41 comes into contact with the second spring 46 and receives an upward bias. At this time, since the total mass of the sale product A1 is received by the first stopper 41, the mass of the sale product A1 overcomes the urging force of the first spring 45 and the second spring 46, and the first stopper 41 is further moved. Rotate downward.

  If the first stopper 41 is rotated about 180 ° from the locking position to the downward paying position, the sale product A1 is lowered from between the rear heat insulating wall 14a and the first stopper 41. , Falls in the commodity drop passage 20 and is paid out to the sales outlet 21 through the chute 22.

  When the commodity A1 is released from the first stopper 41, the first stopper 41 is quickly rotated upward by the urging force of the first spring 45 and the second spring 46 to return to the locking position.

  On the other hand, when the second drive pin 55 moves from the first rear position to the second front position, the tip of the second stopper 42 is placed on the inclined shelf 25 with the sale item A1 and the next sale item A2. This second stopper 42 locks the next sale product A2 that moves backward as the sale product A1 moves backward.

  At this time, since the upper and lower regulating plates 71 are in contact with and pressed against the upper surface of the next sale product A2, the next sale product A2 does not get over the second stopper 42, and the next sale product A2 is moved to the second stopper 25. Can be securely locked. Further, even if the next sale product A2 is lifted by the tip of the second stopper 42, the height dimension from the position where the upward swing of the vertical restriction plate 71 is restricted to the upper surface of the lower inclined shelf 25 is Since the next sale product A2 is set to be smaller than the sum of the height dimension of the second stopper 42 projecting on the inclined shelf 25 and the second stopper 42 projecting on the inclined shelf 25, the next sale commodity A2 does not get over the second stopper 42, The next sale product A2 can be securely locked by the second stopper 25.

  Further, at the timing when the first stopper 41 returns to the locking position, the excitation of the solenoid 49 is released, and the first drive pin 54 and the second drive pin 55 are moved forward by the first force by the spring 56. Move from the position to the first rear position.

  At this time, the first drive pin 54 moves along the return-side movement path 63 (path indicated by a two-dot chain line in FIG. 5) of the guide groove 61, and returns to the locking position. It is possible to reliably return to the first position without contacting the cam portion 60.

  The first drive pin 54 returned to the first rear position abuts against the first cam portion 59 and holds the first stopper 41 in the locking position. The second stopper 42 retreats to the retreat position below the inclined shelf 25, and the next sale product A2, which has been locked by the second stopper 42, moves the inclined shelf 25 rearward, and the first stopper 41 It abuts and stops, and waits for the next payout operation.

  As described above, the product dispensing device 19 is provided so that the first stopper 41 can turn on the end side (near the end portion) facing the product dropping passage 20 of the inclined shelf 25, and the first stopper 41 is the product. Since the inside of the fall passage 20 is used to rotate between the payout position where the sales product A1 is paid out downward from the locking position for locking the sales product A1 on the inclination shelf 25, the conventional inclination shelf It is not necessary to secure a retreat space for the first stopper to fall down in the rear area, and the retreat space can be effectively used for storing the product A on the inclined shelf 25, so that the product storage amount can be increased, or The depth dimension can be reduced. Therefore, it is possible to reduce the depth dimension of the vending machine 11 while securing the amount of goods stored on the inclined shelf 25.

  Since the first spring 45 that biases the first stopper 41 toward the locking position and the second spring 46 that biases the first stopper 41 upward from the downward payout position are provided. The biasing force of the first spring 45 can be set to a relatively weak biasing force that allows the product A1 on the inclined shelf 25 to move toward the product dropping passage 20 due to its own weight, and is paid to the product dropping passage 20 When the released sales commodity A1 is removed from the first stopper 41, the first spring 41 can be quickly and reliably returned from the downward payout position to the locking position by the second spring 46. it can.

  In order to guide the first drive pin 54 that moves from the first position toward the second position by the guide groove 61 to the forward path moving path 62 that contacts the second cam portion 59 of the first stopper 41. The first stopper 41 is forcibly rotated toward the product drop passage 20 to smoothly start the movement of the sales product A1 that has been locked by the first stopper 41 toward the product drop passage 20. In addition, the guide groove 61 prevents the first drive pin 54 moving from the second position toward the first position from contacting the second cam portion 60 of the first stopper 41. In order to guide to the return path side movement path 63, the first stopper 41 can be reliably returned to the locking position and the first drive pin 54 can be reliably returned to the first position.

  A mounting portion 36 is bent from the edge of the notch 35 provided on the end side facing the product drop passage 20 of the inclined shelf 25 to the lower surface side of the inclined shelf 25, and the first stopper 41 and the second stopper 41 are attached to the mounting portion 36. Since the stopper 42 is rotatably attached and the drive mechanism 43 for operating the first stopper 41 and the second stopper 42 is provided on the lower surface of the inclined shelf 25, the first stopper 41 and the second stopper are provided on the inclined shelf 25. 42 and the drive mechanism 43 can be integrated, the configuration can be simplified, and the drive mechanism 43 is provided on the lower surface of the inclined shelf 25, and there is no protrusion on the side of the inclined shelf 25. The width of 19 can be narrowed, and the width of the heat insulating walls 14a, 18 can be increased by that amount to improve the heat insulation.

  A spring 56 for pulling back the connecting plate 53 moved by driving the solenoid 49 of the drive mechanism 43 is arranged between the inclined shelf 25 and the connecting plate 53 and stretched between the connecting plate 53 and the inclined shelf 25. The spring 56 can be installed without affecting the operation of the stoppers 41, 42 and the like.

  The flange portions 32a are bent from both sides of the inclined shelf 25 to the lower surface side, and the inclined shelf 25 is attached to the heat insulating walls 14a and 18 on both sides by the flange portions 32a on both sides, so that the heat insulating walls 14a and 18 are attached to the side portion of the product A. Since it uses as a guide surface, the width | variety of the goods delivery apparatus 19 can be made narrower.

  The height dimension from the position where the upward / downward regulation plate 71 is prevented from swinging upward to the upper surface of the lower inclined shelf 25 is the height dimension of the product A, which is the minimum height of the target products, and the upper height of the inclined shelf 25 Since the height of the second stopper 42 projecting to the height of the second stopper 42 is set to be smaller than the sum of the projecting height dimensions, the product A having the minimum height does not get over the second stopper 42 projecting on the inclined shelf 25 and The two stoppers 25 can be securely locked.

  In order to detect by the sold-out switch 75 that the vertical regulation plate 71 has swung below the height of the product A having the minimum height on the lower inclined shelf 25, the vertical regulation plate 71 is also used as the Can be sold out.
