Description

Multistation sack filling machine Technical Field The invention relates to the technical field of material packaging, in particular to a multi-station bagging machine. Background The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. Bagging machines (also known as packaging machines) are automated packaging devices that are widely used in the food, consumer and other industries. In the related art, a known multi-station bagging machine has the working process that a bag taking module sleeves a packaging bag from a bag storage module on a bag opening unit positioned at a bag receiving station, the bag opening unit opens a bag opening of the packaging bag, then a rotating disc rotates to switch the bag opening unit to a material receiving station, a material pushing module pushes materials into the packaging bag by a conveying mechanism, and finally a transferring module removes the packaging bag filled with the materials from the bag opening unit and transfers the packaging bag to a sealing module for sealing. During the operation, the stable operation of the system depends on the cooperative cooperation of the modules. However, in actual production, the following abnormal situation often occurs that after the pushing action is completed, the packaging bag filled with the material is not taken out normally and still remains on the bag-supporting unit due to the failure of the transfer module (such as bag-taking failure, blocking, action lag, etc.) or the mechanical blocking of the bag-supporting unit itself. At this time, if the rotary disk continues to rotate, the bag opening unit will carry the residual packaging bag to enter the bag receiving station again. When the residual packaging bag enters the bag receiving station again along with the bag opening unit, the bag taking module sleeves a new packaging bag on the bag opening unit again according to a preset program, so that the phenomenon of overlapping bagging of sleeving a new bag on the existing packaging bag occurs. The abnormal state can cause a series of linkage problems that new packaging bags cannot be normally opened, so that material clamping and bag breaking occur when a material pushing module pushes materials, and overlapped packaging bags can be clamped between a rotating disc and other modules, so that equipment is stopped and even mechanical damage is caused. Currently, aiming at the abnormal conditions, a manual inspection mode is generally adopted in the industry for processing. Operators need to periodically patrol and examine to see whether residual packaging bags exist on each bag supporting unit or not, or shut down and clean the bag supporting units after the equipment has clamping stagnation faults. The processing mode has the following defects that firstly, manual inspection depends on experience and responsibility of operators, real-time and full-coverage monitoring is difficult to achieve, abnormality can be found after faults are caused, secondly, a bag opening unit is located in a continuously running operation area, large potential safety hazards exist in manual approaching observation, and furthermore, frequent shutdown cleaning can interrupt production beats, so that continuity and production efficiency of packaging operation are seriously affected. Disclosure of Invention In view of the above, the present invention aims to provide a multi-station bagging machine, which is expected to automatically identify and process the bag residual abnormality on the bag opening unit without manual intervention, and ensure continuous and stable operation of the multi-station bagging machine. The aim of the invention is achieved by the following technical scheme: the invention provides a multi-station bagging machine, which comprises: The bag supporting module comprises a rotary disk and a plurality of bag supporting units arranged on the rotary disk, wherein the rotary disk is configured to rotate around the axis of the rotary disk so as to drive each bag supporting unit to be sequentially switched between a bag receiving station and a material receiving station; The detection component is arranged corresponding to the bag receiving station and is used for detecting whether a packaging bag exists on a bag supporting unit positioned at the bag receiving station; the cleaning module is arranged corresponding to the bag receiving station and is used for removing the packaging bag on the bag supporting unit of the bag receiving station; The control module is electrically connected with the detection component and the cleaning module respectively and is configured to: When the detecting part detects that the bag opening unit at the bag receiving station has a packaging bag, recording a one-time detecting result; When the same bag opening unit enters the bag receiving station again after undergoing a complete working cycle, before the bag opening unit is slee
