Description

Technical Field

[0001] The utility model relates to an assembly line for a carrier to move forward, in particular to a driving device for driving the carrier to move forward on the assembly line. Background Art

[0002] The assembly line is used to realize the long-distance transportation of goods. When realizing the transportation of goods, it is necessary to use a carrier to clamp or hold the goods. For large places, such as supermarkets, under normal circumstances, the goods in the supermarket are placed in various places according to categories. When selling online, it is necessary to use the assembly line set up in the supermarket to collect the goods ordered by users online to the background for unified and centralized packaging and distribution. In the application place, it is necessary to set up a guide rail to communicate with various areas in the place. A plurality of carriers need to be set on the guide rail, and the carrier is used to transport the items to be transported. To realize the transportation of the carrier, it is also necessary to set a power mechanism along the direction of the guide rail. The power mechanism is adapted to the setting position of the guide rail, and the power mechanism is used to push the carrier on the guide rail. A hanging structure is set at the upper end of the carrier, and the hanging structure is movably hung on the guide rail. The power mechanism generally directly pushes the hanging structure to make the carrier move forward on the guide rail.

[0003] A Chinese patent document (publication number: CN 205366835U) discloses a garment system carrier transfer device, which belongs to the field of garment making equipment and solves the problem that the existing carrier transfer device cannot adapt to the transfer requirements of carriers of different weights. The technical solution adopted is: a garment system carrier transfer device, which is used to be fixed on a chain, including a base plate, a pair of rollers are rotatably provided on the back side of the base plate, an L-shaped lever is provided on the front side of the base plate, one end of the lever is pivotally connected to the base plate through a pivot, and a spring on the base plate acts on the lever, characterized in that a sub-plate is superimposed and fixed on the front side of the base plate.

[0004] This transfer device is used to push the carrier on the ring track forward. When working, the chain drives the lever to move along the ring track, thereby pushing the carrier forward on the ring track. Since the chain itself is relatively unstable, the contact stability between the lever and the roller of the carrier on the ring track cannot be guaranteed, which makes the travel stability of the carrier on the ring track poor, which is not conducive to the smoothness of the carrier's track change on the assembly line.

This further ensures the matching stability between the force-bearing component on the carrier and the driving port, and also facilitates the force-bearing component to smoothly enter the driving port, meeting the actual working requirements.

[0019] In conjunction with the drawings of the specification, the vehicle driving device is arranged in an assembly line, and the assembly line includes a ring rail, which is generally a closed-loop structure. The vehicle driving device is used to push the vehicle on the ring rail forward. The structure of the vehicle driving device includes a flexible driving belt, which is arranged at intervals on the upper side of the ring rail along the direction of the ring rail. The driving belt is a chain structure, which is formed by a plurality of chain links 2 by hinged end to end, and the chain link 2 is a rod structure. A plurality of walking structures 1 are fixed separately on the upper side of the driving belt, and the walking structure 1 is a wheel structure with vertical rollers and horizontal rollers. The walking structure 1 is connected to the walking cavity of the track, and the walking structure 1 can roll forward in the walking cavity. The vehicle driving device also includes a driving block 3, which is block-shaped and is vertically fixed on the bottom surface of the chain link 2. A fixing bolt 8 is provided through the chain link 2, and the lower end of the fixing bolt 8 extends to the lower side of the chain link 2, and the lower end of the fixing bolt 8 is threadedly connected to the driving block 3. A driving block 3 is connected and fixed to a chain link 2, and a driving block 3 is fixed to the chain link 2 by two fixing bolts 8. A driving rod 4 is also fixed on the bottom surface of the driving block 3, and the driving rod 4 extends vertically toward the lower side of the driving block 3. The driving belt is connected to the wheeled power mechanism in a transmission manner. Driven by the power mechanism, the driving belt moves along the direction of the ring track, thereby driving the driving rod 4 to push the vehicle on the ring track forward. In order to improve the contact stability between the driving rod 4 and the force-bearing parts of the vehicle, a cushion sleeve 5 is also sleeved on the outer periphery of the driving rod 4. The cushion sleeve 5 is generally made of a material with a certain elasticity such as rubber or silicone.

[0020] In order to ensure stable transmission between the driving rod 4 and the force-bearing component on the carrier, a movable part is provided on the driving block 3, and the movable part is located on the outside of the driving rod 4. The movable part is movably arranged on the driving block 3. A driving port 6 is formed between the movable part and the driving rod 4, and the driving port 6 is used to accommodate the force-bearing component on the carrier. A limiting part is provided on the driving block 3, and the limiting part is used to limit the inner end of the movable part in one direction to prevent the force-bearing component on the carrier from being disengaged from the driving port 6 when the carrier is pushed. The driving port 6 is formed at the outer end of the movable part.

[0021] In the traveling direction of the driving belt, a mounting opening 11 is formed at the front end of the driving block 3. The movable member is a sheet-shaped movable sheet 10, which is hinged in the mounting opening 11 through a pivot 7, and the pivot 7 is bridged on the mounting opening 11. The limiting member is a limiting column 9, which is also bridged on the mounting opening 11. The limiting member is located on the inner side of the movable sheet 10, and a notch is formed on the side of the movable sheet 10 facing one end of the limiting member, and the notch is used to cooperate with the limiting column 9 to achieve unidirectional limiting of the movable sheet 10. The outer end of the movable sheet 10 is a cam surface, and the outer end of the movable sheet 10 normally extends to the lower side of the lower end of the driving block 3.

[0022] When the driving block 3 moves forward along the circular track, after encountering the carrier on the circular track, the movable sheet 10 is pushed by the force-bearing component on the carrier and moves on the driving block 3, and extends into the installation port 11. The force-bearing component enters the driving port 6 and receives the thrust of the driving rod 4, so that the carrier moves forward on the circular track. If the force-bearing component wants to disengage from the driving port 6, the force-bearing component pushes the movable sheet 10 in the reverse direction. Under the limiting action of the limiting column 9, the movable sheet 10 blocks the force-bearing component in the reverse direction, so that the force-bearing component can be stably maintained in the driving port 6. The limiting position of the movable sheet 10 on the force-bearing component is not stable. The position of the track-changing mechanism at the circular track is lower than the position of the circular track. When the carrier needs to change track, the force-bearing component on the carrier can easily disengage downward from the driving port 6 to realize the track change and diversion of the carrier.
