Technical Field

The invention belongs to the field of container processing mechanical equipment, and particularly relates to a tank body conveying system.

Background

The tank body mainly refers to a cylindrical closed container which can be used for storing materials. In the manufacture of metal cans for holding products such as carbonated beverages, the exterior surface of the can body needs to be patterned with different coatings. In the conveying process after the printing process and before the drying process, the printed patterns cannot be touched so as to avoid damage.

The existing related tank conveying systems are generally: and blowing the can bodies with the finished surfaces printed onto a middle rotating disc from the rotatable printing rotating disc, and blowing the can bodies onto a next conveyor from the middle rotating disc. The conveyer belt adopts a pin chain, and the tank body is hung on the pin chain, so that the outer surface of the tank body is ensured not to be contacted with foreign objects. That is, the blowing handover method requires an additional transfer disk device, which makes the system structure complicated, contrary to the simplification of the equipment and the cost control.

Additionally, in prior related can body conveyor systems, the metal cans are typically transported to the oven by a single row of continuous pin chain conveyors. Typical pin ovens have multiple U-shaped pin chain paths to extend the distance the can passes through the oven to ensure toasting time. Typical can body baking time is 10 seconds and can body production speed is 1800 cans per minute, corresponding to a typical pin chain oven with an oven tunnel of 32 meters. Therefore, the existing single-row tank body pin chain conveying can also cause the problems of large volume and large energy consumption of the oven equipment. Meanwhile, the problem of poor flexibility still exists in the whole continuous transmission of the pin chain, because in the actual production process, the production speed of the front and back processes is inevitable to be uncoordinated due to various abnormalities, at the moment, the whole continuous transmission of the pin chain can influence the quality of the product through the process time influencing the product, the productivity of a production line can be directly influenced, and the production cost is indirectly increased.

The pot positioning locations 11 are evenly distributed around the circumferential direction on the disc surface of the turntable 1.

The blanking conveying line 2 is provided with a vertical conveying surface 21 and a transverse conveying surface 22, the vertical conveying surface 21 is vertically arranged and faces the disc surface of the turntable 1, the transverse conveying surface 22 is arranged along the horizontal plane, and the transverse conveying surface 22 faces upwards; the vertical conveying surface 21 and the horizontal conveying surface 22 are provided with adsorption holes 41, and the back surfaces of the vertical conveying surface and the horizontal conveying surface are provided with negative pressure mechanisms so as to adsorb the tank body 3 in a working state.

Two conveying paths 4 are arranged in parallel in the longitudinal direction of the vertical conveying surface 21, and the area, facing each conveying path 4, on the turntable 1 is used as a blanking cross-connecting area 12; the pot positioning locations 11 of the blanking interface 12 are arranged adjacent to one another on the rotary disc 1. In the blanking state, the can positioning positions 11 in the blanking cross-connecting area 12 correspond to and align with the conveying paths 4 of the vertical conveying surface 21 one by one, so that the can bodies 3 at the can positioning positions 11 in the blanking cross-connecting area 12 can be transferred to the corresponding conveying paths 4 separately from the rotary table 1.

A blowing device is further arranged on the blanking cross connection area 12 and serves as a releasing mechanism; in the blanking state, when the can body 3 is positioned at the can positioning position 11 at the downstream end in the blanking cross-connecting area 12, the releasing mechanism is started to enable the can body 3 to be separated from the disc surface of the rotary disc 1.
