Description

Technical Field

[0001] The present invention relates to the technical field of vending cabinet devices, in particular to the technical field of an out-of-stock control device for an inclined shelf of a vending cabinet.

Background Art

[0002] An automatic vending cabinet is a commonly used device for commercial automation. It is not restricted by time and location, can save labor and facilitate transactions. Vending cabinets can be set up both indoors and outdoors to complete self-service sales. The goods on the inclined shelf in the automatic vending cabinet are all controlled by an out-of-stock device to be shipped out in an orderly manner.

[0003] Chinese Patent Publication No. CN207264489U, Publication Date: April 20, 2018, Invention Title: A Vending Cabinet Out-of-Stock Device. This application discloses a device including a base, a front pressing plate, a transmission plate, and a rear lifting plate. The base and the front pressing plate are connected by a first support rotating shaft. A hinge torsion spring is installed on the base. The front pressing plate is provided with a plurality of rotating connection parts and a first support rotating shaft installation sleeve. The top of the front pressing plate is provided with a plurality of arc-shaped heads. The front pressing plate and the transmission plate are connected by a second support rotating shaft. The transmission plate and the rear lifting plate are detachably connected. The transmission plate is provided with a plurality of second support rotating shaft installation sleeves, and a goods blocker is installed on the rear lifting plate. Its disadvantages are that during the downward pressing process of the front pressing plate, the first item on the inclined shelf will move slightly upward, causing the first item and the subsequent items to arch up. The gap generated by the arching will cause the goods blocker on the rear lifting plate to not effectively block the downward trend of the subsequent items when the first item slides into the receiving tray, resulting in the subsequent items also sliding into the receiving tray one after another, leading to chaotic out-of-stock and generating noise, and even damaging the out-of-stock device and the automatic vending cabinet; it is necessary to replace and select the rear lifting plate with a corresponding goods blocker according to the shape characteristics of the goods to meet the loading and out-of-stock requirements of the inclined shelf, which is rather cumbersome.

[0022] The working process of the present invention:

[0023] During the working process of a shipment control device for an inclined shelf of a vending cabinet according to the present invention, goods are orderly arranged on the inclined shelf 9 in the vending cabinet. There is a shipment control device under each column of goods. In the initial state, the arc-shaped goods blocking piece 32 on the goods blocking piece 3 blocks the goods on the inclined shelf 9. When shipment is required, the goods pushing device at the bottom of the goods receiving tray 91 pushes the push rod upward to pass through the through groove on the inclined shelf 9 and pushes the lower pressing plate 2 downward. At this time, the torsion spring 11 between the lower pressing plate 2 and the bottom support 1 is in a compressed state. While the lower pressing plate 2 is pressed downward, it drives the goods blocking piece 3 downward and the transmission plate 4 upward. The arc-shaped goods blocking piece 32 on the goods blocking piece 3 will rotate downward along an arc trajectory with the fixed shaft 12 as the center of the circle. The first piece of goods slides from the static state to the goods receiving tray 91. At the same time, the transmission plate 4 moves upward to drive the spring piece 5 upward. The front stop block 8 and the rear stop block 7 on the spring piece 5 effectively block the second and subsequent pieces of goods. After the first piece of goods slides into the goods receiving tray 91, the goods pushing device retracts the push rod, and the torsion spring 11 releases its elastic potential energy to make the lower pressing plate 2 return to the initial position. The upward reset movement of the lower pressing plate 2 drives the goods blocking piece 3 upward and the transmission plate 4 downward. While the lower pressing plate 2 is reset, it drives the goods blocking piece 3 downward and the transmission plate 4 upward. At this time, the downward movement of the transmission plate 4 drives the spring piece 5 downward and compresses it. The rebound effect of the rebound piece 6 and the spring piece 5 itself can make the two return to the initial position. The second and subsequent pieces of goods blocked by the front stop block 8 and the rear stop block 7 on the spring piece 5 slide downward from the static state. At the same time, the arc-shaped goods blocking piece 32 on the goods blocking piece 3 will rotate upward along an arc trajectory with the fixed shaft 12 as the center of the circle until it returns to the initial position to block the second piece of goods sliding downward. Among them, by adjusting the distance between the front stop block 8 and the rear stop block 7 on the spring piece 5, the shipment control requirements for goods of different sizes and shapes can be met. When the fixed shaft 12 is installed, it passes through the inside of the torsion spring 11 and the fixed shaft installation part 24. The rotating shaft 22 is cooperatively installed on the shaft limiting part 41 on the transmission plate 4 and the rotating shaft installation part 21 on the inclined plate. The arc-shaped goods blocking piece through groove on the transmission plate 4 is used for the arc-shaped goods blocking piece 32 to rotate through.

The left ends of the lower pressing plate 2 and a transmission plate 4 are rotatably connected with a rotating shaft 22. A spring piece 5 is fixed on the transmission plate 4. When the lower pressing plate 2 is pressed down, the arc-shaped goods blocking piece 32 on the goods blocking piece 3 moves along a movement track with the fixed shaft as the center of the circle, so as to prevent the goods blocking piece 3 from pushing the first commodity, thereby ensuring that the first commodity remains stationary before sliding into the receiving tray 91 and will not arch with subsequent commodities, ensuring the smoothness and safety of out-of-stock; a plurality of block mounting holes 51 are provided on the spring piece 5, and a front block 8 and a rear block 7 are detachably mounted on the block mounting holes 51, facilitating the adjustment of the distance between the front block 8 and the rear block 7 to realize the out-of-stock control of different types of commodities; a rebound piece 6 is provided at the right end of the spring piece 5, and a torsion spring 11 is provided between the lower pressing plate 2 and a bottom bracket 1, ensuring the reset of the spring piece 5 and the lower pressing plate 2 through an elastic effect, ensuring the normal use of the out-of-stock control device; an arc-shaped goods blocking piece through groove with the same number as the goods blocking piece 3 is provided on the transmission plate 4, ensuring the smooth rotation of the arc-shaped goods blocking piece 32 on the goods blocking piece 3 around the fixed shaft 12; a plurality of spring piece mounting holes 42 are provided at the right end of the transmission plate 4, a plurality of fixed mounting holes 52 are provided on the spring piece 5, a plurality of goods blocking piece mounting holes 23 are provided on the lower pressing plate 2, and a plurality of block mounting holes 51 are provided on the spring piece 5. The front block 8 and the spring piece 5, the rear block 7 and the spring piece 5, the lower pressing plate 2 and the goods blocking piece 3, and the spring piece 5 and the transmission plate 4 are all fixed with a plurality of fastening screws, making the out-of-stock control device convenient to disassemble and assemble; the out-of-stock control device effectively controls out-of-stock through the transmission among the lower pressing plate 2, the goods blocking piece 3, the transmission plate 4, the spring piece 5, and the rebound piece 6.
