The device is used for detecting the work of the PET packer so as to automatically detect whether the packing belt is in a belt breaking state, and the specific process is as follows:
1. the automatic belt breakage detection device of the packing machine is in an initial state, and the detection swing rod 2 is in a horizontal position as shown in fig. 2;
2. the packing machine performs packing operation, the packing belt 9 is tightened, the stress end of the detection swing rod 2 is pressed down under the action of the pulling force of the tightened packing belt 9, the detection end is lifted, the sensor 1 detects that the detection swing rod 2 is lifted, and at the moment, the automatic detection device for the broken belt of the packing machine is in a detection state, as shown in fig. 3; the following two conditions occur during tightening of the strapping band 9:
case one: when the packing belt is tightened, the packing belt is intact, the automatic detection device for the broken belt of the packing belt is always in a detection state, the sensor 1 always keeps a signal within a set time, the packing belt is judged not to be broken, and the packing belt is subjected to subsequent operation;
and a second case: when the packing belt is tightened, the packing belt is disconnected due to uncertain factors, and the detection swing rod 2 in the detection state loses the tension of the packing belt and is pulled back to the initial position by the return spring 4; at the moment, the sensor 1 loses the signal, the control element of the packer detects that the signal retention time of the sensor is less than the set time, the packing belt is judged to be disconnected, the subsequent packing operation is not performed any more, and an alarm is sent to inform related personnel to process; after the treatment is finished, the packaging operation is carried out again, and the automatic detection device for broken belt of the packaging machine reenters the working cycle;
3. the baling press carries out the receipts area and welding operation to the baling belt, can appear following two kinds of situations this moment:
case one: the packing operation of the packer is completed, the packing belt is not broken, the automatic detection device for broken belt of the packer is always in a detection state, the sensor 1 always keeps a signal within a set time, the packing belt is judged not to be broken, the packer performs subsequent operation, the detection swing rod 2 is pulled out of the packing belt and is pulled back to an initial position by the return spring 4, and the whole working cycle is finished and ready to enter the next working cycle;
and a second case: after the packing belt welding operation is finished, the packing belt is broken due to various uncertain factors, and the detection swing rod 2 in the detection state loses the pulling force of the packing belt and is pulled back to the initial position by the return spring 4. At the moment, the sensor 1 loses the signal, the control element detects that the signal holding time of the sensor is less than the set time, the packaging belt is judged to be disconnected, the subsequent packaging operation is not performed any more, and an alarm is sent to inform related personnel to process; and (5) after the treatment is finished, re-carrying out packaging operation, and re-entering the working cycle by the automatic detection device for broken belt of the packaging machine.
In the packing process, after the packing belt 9 finishes the belt winding and welding, the detection swing rod 2 needs to be pulled out of the packing belt 9, at this time, because the detection swing rod 2 is in an inclined state, in the ascending process of the machine head, the detection device is wholly lifted, the stress end of the detection swing rod 2 continuously swings downwards and is gradually pulled out from the lower part of the packing belt 9 (as shown in fig. 4), and the process is irrelevant to the moving direction and the moving state of the packed object.
