Detailed Implementation

[0026] The present invention will be further described below through specific embodiments.

[0027] Reference Figures 1 to 6 As shown, a lifting device for a shoe last carrier is used to transport the shoe last carrier between two vertically arranged conveyor lines to achieve uninterrupted cyclic transport of the shoe last carrier. The device includes a housing 1, a conveyor mechanism 2, and a lifting mechanism 3. The upper conveyor line is used to drive the shoe last carrier loaded with shoe lasts along the conveying direction to process the shoe lasts accordingly. The lower conveyor line is used to transport the used shoe last carrier back. During operation, the aforementioned lifting devices can be installed at both ends of the conveyor lines to move the used shoe last carrier downwards to the lower conveyor line, and then, in conjunction with another lifting device, move the shoe last carrier from the lower conveyor line upwards to the upper conveyor line for reuse.

[0028] The outer casing 1 is located at the end of the conveyor line and has a mounting cavity 11 for mounting the conveying mechanism 2 and the lifting mechanism 3.

[0029] The conveying mechanism 2, which can be opposite to the upper or lower conveyor line, receives shoe last carriers conveyed from the upper or lower conveyor line. It includes a conveyor base 21, two conveyor chains 22 oppositely disposed on both sides of the conveyor base 21, a drive assembly 23 mounted on the conveyor base 21 and connected to and driving the conveyor chains 22, two blocking side plates 24 oppositely disposed on the conveyor base 21 and located on the outer sides of the two conveyor chains 22, a blocking rear plate 25 mounted on the conveyor base 21 and located at the rear ends of the two conveyor chains 22, two connecting blocks 26 oppositely disposed on the conveyor base 21 and connected to the opposite two conveyor chains 22, and sensors 27 mounted on the conveyor base 21 for detecting whether the shoe last carrier is in position. Specifically, two sensors 27 are provided, spaced apart on the conveyor base 21 along the direction of movement of the shoe last carrier. The cooperation of the two sensors 27 controls the operation of the conveyor chains 22, ensuring stable conveying of the shoe last carrier to the two conveyor lines. The shoe last is fed onto the chain 22 and then lifted or lowered by the lifting mechanism 3 to the corresponding conveyor line. The sensor 27 can be a proximity sensor. Furthermore, the connecting block 26 is L-shaped, and its two ends are connected to the conveyor seat 21 or the conveyor chain 22 by bolts. After the shoe last carrier is used, the worker or robot removes the shoe last from the shoe last carrier. The shoe last carrier continues to be conveyed outward to the corresponding conveyor mechanism 2, so that the two ends of the shoe last carrier are supported on the corresponding conveyor chains 22. When the sensor 27 at the front end detects the shoe last carrier entering, the drive component 23 controls the conveyor chain 22 to work according to the feedback signal, so that the shoe last carrier continues to move inward into the mounting cavity 11. When the sensor 27 at the rear end detects the shoe last carrier entering, the drive component 23 controls the conveyor chain 22 to stop working according to the feedback signal, so that the shoe last carrier is completely moved into the mounting cavity 11 and supported on the two conveyor chains 22.

[0030] The drive assembly 23 includes a connecting rod 231 connected between the two conveyor chains 22, a drive motor 232 mounted on the conveyor seat 21, a drive gear 233 connected to the output end of the drive motor 232, a driven gear 234 mounted on the connecting rod 231 opposite to the drive gear 233, and a transmission toothed belt 235 sleeved between the drive gear 233 and the driven gear 234. Through the cooperation of the drive motor 232 with the drive gear 233, the driven gear 234 and the transmission toothed belt 235, the two conveyor chains 22 are driven to work simultaneously.

[0031] The lifting mechanism 3 includes a support base 31 connected to the lower end of the mounting cavity on one side of the conveying base 21, a lifting base 32 movable on the support base 31, two connecting pieces 33 respectively connected to the conveying base 21 on both sides of the lifting base 32, a lifting assembly 34 connected to the support base 31 and driving the lifting base 32 to move up and down, and two guide pieces 35 connected to the lifting base 32 on the support base 31. Specifically, the lifting base 32 includes two vertical rods 321 arranged opposite each other and a horizontal rod 322 arranged at the upper end of the two vertical rods 321.

[0032] The connector 33 includes a connecting horizontal plate 331 connected to the lower end of the two vertical rods 321 and connected to the conveyor seat 21, and connecting side plates 332 respectively disposed on the sides of the two vertical rods 321 and connected to the conveyor seat 21. The connecting side plate 332 includes a side plate body 333 with one end connected to the side of the vertical rod 321 and the other end extending downward at an incline, and a connecting part 334 perpendicularly connected to the lower end of the side plate body 333. The conveyor seat 21 is connected to the connecting part 334. By defining the structural composition of the connector 33 and setting two connecting side plates 332 arranged opposite to each other, a stable connection between the lifting seat 32 and the conveyor seat 21 can be achieved.

[0033] The lifting assembly 34 includes a lifting cylinder 341 mounted on a support base 31 and a floating joint 342 mounted at the front end of the lifting cylinder 341 and connected to a crossbar 322. The floating joint 342 is provided to prevent the lifting cylinder 341 from stalling.

[0034] The guide member 35 includes a guide rod 351 extending upward on the support base 31 and two guide sleeves 352 that are spaced apart on the guide rod 351 and connected to the opposite vertical rod 321 respectively. The guide member 35 enables the lifting base 32 to move up and down stably. Specifically, the upper ends of the two guide rods 351 are provided with mounting plates 36 that are connected to the upper end of the mounting cavity 11. The support base 31 and the mounting plates 36 are vertically opposite each other, so that the lifting mechanism 3 is stably installed in the mounting cavity 11.

[0035] After the shoe last carrier is used, it continues to be transported to the corresponding lifting device at the end of the upper conveyor line. The lifting mechanism 3 moves the shoe last carrier that has been moved to the conveyor seat 21 downward to be opposite to the lower conveyor line. Then, the drive component 23 controls the two conveyor chains 22 to work, moving the shoe last carrier to the lower conveyor line for back transport. Then, it is moved upward to the front end of the upper conveyor line by another lifting device for reuse.

[0036] This application uses a limited lifting device, through the cooperation of the conveying mechanism 2 and the lifting mechanism 3, to transfer the shoe last carrier between two layers of conveying lines arranged vertically, so as to realize the cyclic use of the shoe last carrier. It has a high degree of automation, requires no manual intervention, and greatly reduces labor costs.

[0037] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
