Bottle-sticking prevention control method and system for bottle conveyer

Abstract

The invention discloses a bottle-sticking prevention control method and system for a bottle conveyer. The control method comprises the following steps: (1) recording the standard position of each servo shaft of the transmission mechanism of the bottle conveyer during normal operation and presetting an ideal deviation threshold; (2) when the bottle conveyer operates, detecting the actual position of each servo shaft in the bottle conveyer in real time; (3) comparing the standard positions of the servo shafts in the step (1) with the actual positions of the servo shafts in the step (2), and stopping the bottle conveyer to prevent bottle breaking if the differences between the standard positions and the actual positions are greater than the ideal deviation threshold. The control system comprises a control component and a detection component which is used for detecting the positions of the servo shafts in the bottle conveyer. The control method and the control system have the advantages of simple principle, convenience in control, good reliability and the like, can deal with the bottle sticking condition in time to prevent the bottle sticking condition from affecting the working performance of the complete machine.

Description

technical field [0001] The invention mainly relates to the field of packaging equipment for medicine, food, etc., in particular to a bottle anti-jamming control method and system suitable for a bottle conveying device. Background technique [0002] At present, a large number of bottle conveying devices are often used in packaging equipment such as medicine and food. The bottle conveying device is used to complete the conveying of the bottle body. Bottle" phenomenon, and then cause "broken bottle" or other conditions. For example, taking the screw powder packing machine as an example, the bottle feeding part of the screw powder packing machine generally includes the bottle feeding dial, the bottle feeding fence, the bottle feeding track and the bottle unscrambling tray. The bottle enters the bottle-feeding track; then, the medicine bottle will be handed over to the bottle through the bottle-feeding track and the bottle-feeding dial, and a bottle-feeding fence is set around t...

AI Technical Summary

Problems solved by technology

The medicine bottles are running at high speed during the whole process. In the above production process, due to the bottle unscrambler being inverted or the pressure between the medicine bottles in the bottle feeding track is not enough, the medicine bottles will be jammed, Broken bottles etc.

Once a bottle is jammed, the transmission parts such as the dial wheel and the auger will be subject to a great impact, which is easy to cause damage; at the same time, a jammed bottle or a broken bottle will also cause a large mechanical vibration, which will cause the screw filling assembly to appear. The phenomenon of falling powder causes a large deviation in the filling volume

In the existing technology, it is often only possible to use manual inspection to determine whether there are bottle jams or broken bottles. However, due to the very fast conveying speed of the bottle on the production line equipment, once a broken bottle occurs, the broken bottle can be manually judged immediately. Just shut down, but the transmission parts have been destroyed, and the labor intensity has also increased for the workers themselves.
