When passing the cam guide 52 of the slider 50, the second cam member 42 rotates 90 degrees. The second gate plate 41 connected to the second cam member 42 via the coil spring 43 starts to rotate counterclockwise simultaneously with the rotation of the second cam member 42. When the second gate plate 41 rotates counterclockwise in this way, the second gate plate 41 is in the foremost row because there is a product in the foremost row on the trajectory of the second gate plate 41. The rotation is prevented by coming into contact with the product and stops in contact with the product in the front row. In this case, the relationship between the cam protrusion 423 formed on the fitting shaft 422 of the second cam member 42 and the cam protrusion 413 formed in the insertion hole 412 in the bearing portion 411 of the second gate plate 41 is shown in FIG. ), The cam projection 413 is stopped at a position rotated 90 degrees counterclockwise from the standby position (the linear portion in the rear region of the rail 421 is engaged with the cam guide 52), 413 is in a state where it can move without being blocked by the cam projection 423, but the second gate plate 41 abuts against the product in the front row and is restricted from rotating so that the biasing force is applied to the coil spring 43. It is in the state stopped while accumulating. In FIG. 6, the state in which the second gate plate 41 is in contact with the foremost product is shown as a standing state as in the standby state.

  Further, FIG. 6C shows a state in which the slider 50 of the product carry-out mechanism 23 is pushed in to the final position by the advancement of the pressing member provided in the bucket 24. In this state, the cam guide 52 of the slider 50 is engaged with the linear portion of the rear region of the rail 421 in the second cam member 42, while the cam guide 51 of the slider 50 is in front of the rail 321 in the first cam member 32. It engages with the straight part of the rear region through the straight part of the region and the spiral part connecting this straight part and the straight part of the rear region. Here, when the cam guide 51 of the slider 50 starts to engage with the spiral portion from the straight portion in the front area of the rail 321, the first cam member 32 is gradually rotated clockwise, and the spiral portion of the rail 321 is moved to the slider. When the 50 cam guides 51 are passed, the first gate plate 31 rotates 90 degrees and moves from the advance position to the product storage passage to the retracted position. Even when the first gate plate 31 moves from the advance position to the product storage passage to the retracted position, the second gate plate 41 is in contact with the front row of products.

  As shown in FIG. 6C, when the first gate plate 31 moves from the advance position to the product storage passage to the retracted position, the products in the front row stored in the product storage passage are inclined by the inclination of the product storage rack 20. It moves forward by the urging force of the second gate plate 41. At this time, the bridging member 25 (see FIG. 3) provided at the front end of the product storage passage is pushed by the product and tilts, and straddles between the product storage rack 20 and the bucket 24. As a result, the products in the forefront row are surely carried out without disturbing the posture by the bridging member 25 that fills the gap between the product storage rack 20 and the bucket 24. When the products in the front row are carried out in this way, the second gate plate 41 that has been in contact with the products in the front row until then loses its support, and thus rotates counterclockwise by the biasing force of the coil spring 43. . This state is shown in FIG. The second gate plate 41 rotated in the counterclockwise direction has a cam projection 413 formed in the insertion hole 412 in the bearing portion 411 abuts a cam projection 423 formed on the fitting shaft 422 of the second cam member 42. It is held at a position rotated 90 degrees counterclockwise from the retracted position, that is, a position advanced into the product storage passage. As described above, the second gate plate 41 advances into the product storage passage while coming into contact with the product in the front row, so that the second gate plate 41 is interrupted between the product in the front row and the next sale product and the next sale. Hold the product. Thereby, it is possible to reliably prevent the next sale product from being carried out together with the product in the front row.

  When the pressing member provided in the bucket 24 starts to move backward from forward movement, the slider 50 of the commodity carry-out mechanism 23 returns to the standby position by the urging force of the return spring 54. In the returning process of the slider 50, first, the first gate plate 31 is rotated from the retracted position retracted from the product storage passage to the advanced position by the spiral portion of the rail 321 of the first cam member 32, and then the second cam member 42. The second cam member 42 is rotated clockwise by the spiral portion of the rail 421. At this time, the cam projection 413 formed in the insertion hole 412 in the bearing portion 411 of the second gate plate 41 contacts the cam projection 423 formed on the fitting shaft 422 of the second cam member 42 by the biasing force of the coil spring 43. Since the second cam member 42 rotates in the clockwise direction since it is in contact with the second gate member 41, the second gate plate 41 rotates 90 degrees in the clockwise direction from the advanced position where the second gate plate 41 has advanced into the product storage passage and returns to the retracted position. By returning the second gate plate 41 to the retracted position, the next sale product held on the second gate plate 41 moves forward and is held on the first gate plate 31 that has advanced into the product storage passage. When the slider 50 returns to the standby position, the cam guides 51 and 52 of the slider 50 engage with the straight portions of the front areas of the rails 321 and 421 of the first cam member 32 and the second cam member 42, respectively. The second gate plate 41 is held at the retracted position at the advanced position where the plate 31 has advanced into the product storage passage, and enters a standby state.

  When the next sale product moves forward and collides with the first gate plate 31, the next sale product rotates and tilts so that the bottom moves forward with the first gate plate 31 as a fulcrum. However, the disorder of the attitude of the next sale product is suppressed by the bridging member 25. That is, the bridging member 25 is tilted until the foremost row of products is carried out to the bucket 24, but when the foremost row of products is carried to the bucket 24 and the foremost row of products passes through the bridging member 25, the bridging member 25 returns to the standing state. To do. In this way, when the bridging member 25 returns to the standing state, the bottom of the next sale product that has advanced is brought into contact with the bridging member 25, and the posture of the next sale product is suppressed. Therefore, it is possible to prevent the next sale product from falling from the product storage rack 20 or causing the product to be clogged in a state where it is inclined to the front end of the product storage rack 20. The bridging member 25 is configured to come into contact with the barrel portion of the slider 50, and the barrel portion of the slider 50 comes into contact with the bridging member 25 at the standby position to lock it in an upright state, and the slider 50 is pushed in. By constituting so as to be in a free state, it is possible to prevent the bridging member 25 from tilting even when the next sale product collides with the bridging member 25 standing upright.
