Automatic change buffering conveying system
Technical Field
The invention belongs to the technical field of canning or bottling conveying production lines, and particularly relates to an automatic buffering conveying system.
Background
In current canning or bottled production line, be provided with the transfer passage who is used for transporting the bottle jar between each function host computer, traditional transfer passage includes: the mounting bracket is provided with the transport link joint on the mounting bracket, and the transport link joint will be from top to bottom twice host computer intercommunication, and the transport link joint is carried by the host computer of the upper track to the host computer direction of the lower track, is provided with the guardrail on the mounting bracket of transport link joint both sides. When the automatic bottle conveying device works, bottles or cans conveyed by the upper main machine are conveyed to the conveying chain plate of the conveying channel, and then the bottles or cans are conveyed to the lower main machine by the conveying chain plate.
The above-mentioned conveying channel has the drawbacks that: the conveying belt between the upper main machine and the lower main machine has a small number of empty bottles, when the upper main machine fails and stops for a short time to supply bottles, the bottles on the conveying belt are conveyed to the lower main machine without bottles or can be conveyed, so that all equipment behind the lower main machine stops for a long time, and the total output is reduced. When the lower main machine fails and stops, the upper main machine still works, bottles and cans are stacked on the conveying belt and need to be manually conveyed, time and labor are wasted, and the integral yield is reduced if the upper main machine stops working.
In order to improve the fault-tolerant rate of a canning or bottling production line and improve the production efficiency, a buffer platform is added between main functional hosts. The buffering platform is a device special for a buffering function in a production line of the beverage industry and the daily chemical industry, is mainly arranged between functional hosts in the production line and is used for preventing the occurrence of a full-line shutdown accident caused by capacity mismatching after the capacity between an upper host and a lower host is changed due to other factors.
And under the big background of present energy saving and consumption reduction, green's society, each filling factory uses lightweight filling bottle to become the mainstream, and when lightweight filling bottle was used on current dynamic buffer platform, the phenomenon that crowds askew, fall the bottle takes place easily in buffer area, leads to filling bottle wearing and tearing, the waste product to appear when serious, above-mentioned phenomenon is because the too big cause of frictional force between the filling bottle in carrying the buffering process.
On the buffer platform used at present, a plurality of rows of long and long conveying chains are generally used for buffering or the buffer platform is used for buffering. The existing multi-row buffer conveying chain occupies a large space, the buffer function of the existing buffer platform is mainly realized by the guide plates under the combined action of a linear guide mechanism and a linear driving mechanism in a way of reciprocating above two groups of storage conveying belts with opposite conveying directions, and the guide curves of the existing guide plates are mostly linear and arc lines; some buffering platforms, its buffer function pass through the deflector and carry bottle or jar to the buffering on the big conveyer belt, and the conveyer belt periphery is equipped with the conveyer belt that holds single bottle or jar, and when needing, through above-mentioned single row conveyer belt, carry out the bottle jar on the buffering area. But above-mentioned buffering platform bottle flow control is difficult, and pressure between the bottle is big, takes place crowded askew, the phenomenon of empting easily in buffer area, leads to the bottle wearing and tearing when serious, the waste product appears, and the bottle wearing and tearing are severe, need artifical bottle of dredging the buffering, avoids the bottle to damage.
In conclusion, a buffering platform which is suitable for the production line of canned and bottled products and can avoid mutual extrusion is designed, and the buffering platform becomes a new requirement of enterprises of various beverage and daily chemical production lines.
