DETAILED DESCRIPTION

[0027] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0028] See also Figure 1 、 Figure 2 and Figure 3 , which shows a shipping channel device 100 of the present application, which can be configured on a vending machine that sells canned drinks, bottled drinks and other goods. Figure 1 As illustrated in FIG, a plurality of canned beverages 200 are arranged on the delivery lane device 100. The canned beverages 200 can be conveyed forward and leave the delivery lane device 100.

[0029] The delivery channel device 100 includes a channel 1 and a delivery push plate mechanism 2. The delivery push plate mechanism 2 is provided on the channel 1.

[0030] Aisle 1 extends in a front-to-back direction and has a front end 11 and a rear end 12. Aisle 1 is configured to support goods for sale; to this end, the upper portion of aisle 1 provides a flat support surface 101, on which goods for sale can be arranged and supported in the front-to-back direction. Front end 11 defines a liftable access opening 111, to which the vending machine's hopper can be raised and lowered to retrieve goods.

[0031] The delivery push plate mechanism 2 includes a delivery transmission assembly 3 and a push plate assembly 4. The delivery push plate mechanism 2 can push the goods for sale supported on the cargo channel 1 to the lifting and taking port 111 in sequence from front to back.

[0032] The delivery drive assembly 3 includes a gear 31, a front pulley 32, a rear pulley (not shown), and a gear belt 33. The gear belt 33 is tensioned around the front and rear pulleys. The gear 31 is located at the lift access opening 111 of the cargo aisle 1. The gear 31 and the front pulley 32 are coaxial. When the gear 31 is driven to rotate, the front pulley 32 rotates synchronously, driving the gear belt 33 in the forward and backward directions.

[0033] See also Figure 4 、 Figure 5 and Figure 6 The push plate assembly 4 includes a push plate 41, a pressure block 42 and a clamping block 43. The push plate assembly 4 is slidably disposed on the aisle 1 between the front end 11 and the rear end 12 of the aisle 1 along the front-to-back direction relative to the aisle 1.

[0034] The push plate 41 has a horizontal portion 411 and a vertical portion 412. The vertical portion 412 is located in front of the horizontal portion 411. When the push plate assembly 4 is working, the vertical portion 412 abuts against the goods to be sold and can push the goods to be sold forward when moving forward.

[0035] The block 43 is rotatably connected to the push plate 41 between a first position and a second position. Specifically, the block 43 is rotatably connected to the horizontal portion 411 of the push plate 41 via a rotating shaft 430 , and a spring 44 is provided between the block 43 and the horizontal portion 411 .

[0036] The clamping block 43 has a first end 431 and a second end 432 located on both sides of the rotating shaft 431. The clamping block 43 is provided with a plurality of meshing teeth 433 that can mesh with the gear belt 33. The second end 432 is exposed outside the push plate 41.

[0037] The pressing block 42 is fixedly connected to the lower portion of the horizontal portion 411 of the push plate 41. The clamping block 43 is located between the pressing block 42 and the lower portion of the horizontal portion 411. In some embodiments, the pressing block 42 can also be formed integrally with the push plate 41.

[0038] like Figure 8As shown, when the block 43 is in the first position, the several meshing teeth 433 of the block 43 are engaged with the gear belt 33 of the delivery transmission assembly, and the push plate assembly 4 can be driven by the gear belt 33 to move from back to front along the cargo channel 1.

[0039] like Figure 9 As shown, when the block 43 is in the second position, the several meshing teeth 433 of the block 43 are disengaged from the gear belt 33 of the delivery transmission assembly, and the movement of the gear belt 33 will not affect the push plate assembly 43.

[0040] Continue as Figure 1 and Figure 3 As shown, the front end 11 of the cargo aisle 1 is also provided with an insert 13. The insert 13 is opposite to the block 43 in the front-to-back direction. In this example, the insert 13 is opposite to the first end 431 of the block 43 front-to-back. When the push plate assembly 4 slides to the front end 11 of the cargo aisle 1, the insert 13 contacts the first end 431 of the block 43 and triggers the block 43 to switch to the second position, that is, the engaging teeth 433 on the trigger block 43 are disengaged from the gear belt 33. In this state, even if the gear belt 33 continues to move, the push plate assembly 4 can remain stationary under the action of the insert 13. The insert 13 is preferably a triangular structure, and its width gradually widens from the back to the front. In some embodiments, the insert 13 is formed integrally with the cargo aisle 1.

[0041] In this example, the block 43 is constructed so that the operator can manually operate the block 43 to switch it from the first position to the second position. This usually occurs when the goods on the shipping aisle device 100 are sold out and need to be restocked. At this time, the operator needs to manually and quickly retract the push plate assembly 4 to the rear end 12 near the aisle 1. In this example, the operator can manually press the second end 432 of the block 43 to switch the block 43 from the first position to the second position. To facilitate manual operation by the operator, a boss 434 is provided at the second end 432 of the block 43, and the boss 434 is exposed on the outside of the push plate assembly 4. The operator rotates the block 43 by moving the boss 434 with his fingers.

[0042] See also Figure 7 and Figure 9 When the gear 31 at the lifting and taking port 111 of the cargo channel 1 is driven to rotate, it drives the gear belt 33, and the gear belt 33 simultaneously engages with the block 43 on the push plate assembly 4 to drive the push plate assembly 4, so that it pushes the goods out.

[0043] When the last goods in the goods channel 1 are out, the push plate assembly 4 moves to the front end 11 of the goods channel 1, the insert piece 13 on the goods channel 1 is inserted into the push plate assembly 4, and the end of the clamping block 43 is pressed against the spring 44 to rotate an angle, the meshing teeth 433 on the clamping block 43 and the meshing position of the gear belt 33 are disengaged, so that the push plate assembly 4 is prevented from being damaged due to blocking rotation when reaching the most front end position of the goods channel 1; if the meshing teeth 433 and the gear belt 33 are not disengaged in time, the gear belt 33 will drive the push plate assembly 4 to move forward continuously and damage the mechanism even if the rotation of the gear belt 33 is stopped.

[0044] Referring to Figure 9 When the goods in the goods channel 1 are sold out and need to be replenished, in order to quickly replenish the goods, the staff manually presses the convex column 434 of the clamping block 43, the meshing teeth 433 on the clamping block 43 and the meshing position of the gear belt 33 are disengaged, and the disengagement reduces the friction between the mechanisms; the staff can easily push the push plate assembly 4 to the rear end 12 of the goods channel 1, release the convex column 434 of the clamping block 43, and make the meshing teeth 433 on the clamping block 43 and the gear belt 33 re-engage by using the restoring force of the spring 44, and then directly replenish the goods on the goods channel 1.

[0045] The technical scope of the utility model is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the utility model, and these modifications and changes should be within the protection scope of the utility model.
