The conveying belt is usually adopted by iron can product manufacturing and canning enterprises to convey empty cans, particularly, due to the limitation of fields, the conveying of the empty cans sometimes needs to adopt an arch-shaped clamping conveying mode, the empty cans are required to be vertically and uniformly arranged, and once the cans are turned over, the subsequent canning, capping and other production processes are influenced. However, can inversion often occurs due to the unevenness of the belt itself, particularly in vertical turns. If can not in time be found to the reladling, then can damage the iron ladle, block equipment, lead to shutting down, damage conveyer belt equipment even, influence the production efficiency and the economic benefits of enterprise. Therefore, when the production equipment conveys the empty cans, a can-falling detection device is additionally arranged to detect the occurrence of the cans falling on the conveying belt.
According to the difference of the tank inverting and the vertical tank, at least one detector is arranged at a position higher than the tank inverting position and lower than the vertical tank position and used for detecting whether the tank body exists or not, and the detector is arranged at the upper end of the tank body. This already identifies the presence of vertical cans, but in practice the cans on the conveyor are not in close proximity to one another and a gap must exist between the cans. The can pouring detection device provided with only one detector cannot distinguish no can from the can pouring, and the gap between the vertical can and the vertical can be mistaken for the can pouring by the detector. Therefore, a plurality of detectors are combined to form a reladling detection device, so that reladling can be correctly identified.
The can pouring detection device in the current market has certain defects, and the simple can pouring detection device is only provided with an upper trigger switch and a lower trigger switch for detection. When the detection device detects the tank body, the boundary of the tank body needs to trigger two trigger switches simultaneously, and the tank body is identified as a vertical tank; if the lower trigger switch is triggered and the upper trigger switch is not triggered, the can body is identified as a can pour. Because the tank body and the two trigger switch trigger surfaces are interfered by the external environment, the simultaneity of the two trigger switches for detecting the boundary of the tank body is influenced, the detection device is possible to send out a wrong signal for tank pouring, and the signal misjudgment rate is high.
