Description
Technical Field
The invention belongs to the technical field of cigarette equipment, and particularly relates to a PB15 inlet cigarette packet channel rapid switching device and method.
Background
The PB15 cigarette packet storage is a buffer for storing and compensating the cigarette packets of the GDX6S machine set between the small box packaging machine and the transparent paper packaging machine, so that the running inconsistency of the two machines is balanced, the production flow is optimized, and the production efficiency of the cigarette lines is improved; meanwhile, the 'bypass' function of the equipment can be utilized, and when the buffer breaks down, the continuous production of the equipment is ensured. The PB15 tobacco bale memory mainly comprises entry unit, input oar, buffer, output thick liquid, export unit, and the entry part accepts the tobacco bale of capsule packagine machine production, puts the tobacco bale into the buffer through the input oar, and buffer circulates according to the first-in first-out principle, transmits the tobacco bale backward, and output thick liquid draws the tobacco bale from the buffer and puts into export unit, conveys to cellophane packagine machine through the output belt, and whole system keeps moving with the speed that matches the machine of upper reaches. When a PB15 tobacco bale storage device breaks down, the inlet unit switches a tobacco bale conveying path, so that an upstream machine and a downstream machine are directly communicated, and uninterrupted production is realized. In an original control system, a PB15 tobacco bale storage is in a default using state, a tobacco bale conversion device of an inlet unit is switched on a main conveying belt, when the PB15 tobacco bale storage breaks down, an upstream machine is decelerated to a stop state until the tobacco bale in a conversion channel is emptied, the conversion device is started, then the upstream machine is lifted to a normal operation speed, and about 2 minutes is needed in the whole process under the condition that no fault exists in the conversion process. And after the PB15 tobacco bale memory recovers to be normally put into use again, the same flow is still needed, and the conversion process is long. In addition, when the equipment is actually operated, because the inlet switching device acts and the cigarette packet conveying belt is not matched, the switching cylinder acts slowly and the like, the switching failure is caused, the upstream and downstream machines are stopped and standby, production is recovered after the fault is processed, the switching time is longer, and the line operating efficiency is influenced. The main reasons for the long time consumption of the PB15 tobacco bale memory switching process are as follows: (1) the original control system depends on the upstream machine to reduce the speed to zero and to empty the conversion channel tobacco packet, thereby prolonging the conversion process time. (2) The cigarette packet emptying is not thorough due to the fact that no switching channel emptying detection exists in an original control system, so that the switching channel is blocked, the switching processing time is prolonged, and the switching reliability is not high. The prior art has not had a relevant solution and technique to the above-mentioned problems.

step ten: controlling the reversing action of the switching electromagnetic reversing valve to enable a piston rod of the switching cylinder to retract to the inside by a set length, and driving a discharge end of the switching channel to move from the upper part of the feeding end of the auxiliary conveying belt to the upper part of the feeding end of the main conveying belt;
step eleven: detecting and judging whether a piston rod of the conversion air cylinder retracts to a set conversion position through a conversion position detector, controlling a blocking electromagnetic directional valve to perform reversing action after the piston rod of the blocking air cylinder retracts to open a passage in a conversion channel, and controlling a cigarette packet conveying belt servo motor to start through a PARKER servo controller to convey a cigarette packet to a buffer memory through a main conveying belt and convey the cigarette packet to a downstream machine; if the piston rod of the conversion cylinder does not reach the set conversion position, controlling a PB15 tobacco bale storage device to stop, outputting red stop alarm information through a computer, prompting an operator to intervene in processing, and eliminating the alarm information after restarting equipment after processing faults;
step twelve: the handover switching process is completed.
