Description

Technical Field

[0001] The invention relates to the technical field of intelligent logistics, in particular to a roller conveyor belt chain turnover mechanism. Background Art

[0002] Roller conveyors are important conveying equipment for sorting and classification in logistics transportation. At present, the tracks of roller conveyors are mainly used to convey pallets or goods. In some logistics conveying systems, fireproof fast rolling doors are installed, and many fire rolling doors have conveying equipment underneath, such as roller conveyors. Traditional roller conveyors cannot achieve roller flipping, which will affect the transportation of goods at the position of fireproof fast rolling doors or affect the partition status of two workshops.

[0003] Therefore, the use of a roller conveyor with a chain flipping mechanism can ensure that when a fire shutter door falls, there is a gap between the roller conveyors after the effective flipping mechanism flips a certain angle, avoiding interference while ensuring the normal operation of the conveying system and ensuring that the fast rolling door can fall under the floor, thereby meeting fire protection requirements and facilitating the entry and exit of personnel and goods; it is also convenient for the transportation of goods in different production workshops.

[0004] Existing technology: The turning mechanism is a roller conveyor and a roller conveyor, that is, a movable roller conveyor turns around another fixed roller conveyor; the turning mechanism is driven by a chain or a cylinder push-out method. There are the following defects:

[0005] 1. The chain-driven flipping mechanism is used. Because there is a gap between the chain and the sprocket, the flipping mechanism is prone to shaking during the flipping process.

[0006] 2. The roller conveyor's tipping mechanism is a roller conveyor. After the tipping mechanism and the conveying surface are leveled, the gap between the rollers is too large, and the pallet or material can easily get stuck after passing through.

[0007] 3. The service life of the cylinder is short, the maintenance cost is high, and the pipeline is troublesome.

[0008] Fourth, the movable roller conveyor and the fixed roller conveyor are respectively provided with a driving device, so there is an error in the synchronization of the two roller conveyors, and each of them needs a driving device, and the equipment cost of the driving device is relatively high, resulting in a high cost of the entire set of equipment.

[0063] In the description of the invention, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the drawings and is only for the convenience of describing the invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as limiting the scope of protection of the invention.

[0064] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to specific circumstances.

[0065] The inventive concept of the present invention is as follows:

[0066] (1) The turning mechanism 4 is rigidly connected with a connecting rod, so that the turning process is not prone to shaking.

[0067] (2) The chain conveyor 2 is turned around the roller conveyor 1, and the driving sprocket 22 of the chain conveyor 2 is fixed on the rotating shaft 8, so that the rotating axis of the driving sprocket 22 is the same as the rotating axis during turning, that is, the rotating shaft 8, thereby reducing the gap between the chain conveyor 2 and the roller conveyor 1 to prevent the pallet or goods from getting stuck.

[0068] (3) The flip motor 3 is used as the flip driving component. Compared with the prior art using a cylinder, it has a longer service life and does not require the laying of pipelines.

[0069] (4) By fixing the driving sprocket 22 of the chain conveyor 2 on the rotating shaft 8 and using the transmission mechanism 13, the roller conveyor 1 and the chain conveyor 2 can share a driving motor 11. Compared with the prior art, the number of driving devices is reduced and the cost is lower.
