As shown in fig. 2, the packing machine set includes a main machine 201, a subsidiary machine 202, and a cigarette packet transmission channel 203 disposed between the main machine 201 and the subsidiary machine 202, wherein the cigarette packet transmission channel 203 is used for transmitting cigarette packets from the main machine 201 to the subsidiary machine 202.
Fig. 1 is a flowchart of a method for improving the operation efficiency of a packaging unit, specifically, the method for improving the operation efficiency of the packaging unit includes the following steps:
step S101, detecting whether the auxiliary machine 202 is stopped, and generating and outputting a stop signal when the auxiliary machine 202 is stopped;
step S103, detecting whether a cigarette packet exists on the cigarette packet transmission channel, and if so, generating and outputting a confirmation signal;
and step S104, receiving the stop signal and the confirmation signal, and removing the tobacco bale on the tobacco bale transmission channel 203.
Based on the method for improving the operating efficiency of the packing unit, whether the auxiliary machine 202 stops or not and whether the cigarette packet exists in the cigarette packet transmission channel 203 or not are respectively detected, when the two conditions are met simultaneously, tobacco packets on the tobacco packet transmission channel 203 are removed (namely, a stop signal is sent out when the auxiliary machine 202 stops, a confirmation signal is sent out when tobacco packets exist on the tobacco packet transmission channel 203, and the tobacco packets on the tobacco packet transmission channel 203 are removed after the stop signal and the confirmation signal are received), so that when the auxiliary machine 202 stops, the main machine 201 and the tobacco packet transmission channel 203 still operate, the tobacco bale on the tobacco bale transmission channel 203 can be removed, so that the tobacco bale on the tobacco bale transmission channel 203 can not block the main machine 201, the main machine 201 can not stop running, therefore, the number of times of shutdown of the packaging unit is reduced, the operation efficiency of the packaging unit is improved, and a series of quality problems caused by instable instantaneous operation of the cigarette machine during starting are avoided.
It should be noted that the execution sequence of step S101 and step S103 is not required, and step S101 may be executed first, and then step S103 is executed (i.e. whether the auxiliary machine 202 is stopped is detected first, and when the auxiliary machine 202 is stopped, whether a cigarette packet exists on the cigarette packet transmission channel 203 is detected); step S103 may be executed first, and then step S101 is executed (i.e., whether a cigarette packet exists on the cigarette packet transmission channel 203 is detected first, and if a cigarette packet exists, whether the auxiliary machine 202 is stopped is detected); or step S101 and step S103 may be executed simultaneously (i.e., whether a cigarette packet exists on the cigarette packet conveying passage 203 and whether the auxiliary machine 202 is stopped are detected simultaneously).
Specifically, in step S103, whether a cigarette packet exists on the cigarette packet transmission channel 203 is detected, which may be always detected during the operation of the packing unit, or a detection signal is sent to detect whether a cigarette packet exists on the cigarette packet transmission channel 203 after a stop signal is received. For the latter, detecting whether a cigarette packet exists on the cigarette packet transmission channel 203 illustratively includes first determining whether a stop signal is received, and if the stop signal is received, detecting whether a cigarette packet exists on the cigarette packet transmission channel 203. Specifically, when the auxiliary machine 202 is stopped, and after the stop signal of the auxiliary machine 202 is received, a detection signal is generated to control and detect whether a cigarette packet exists on the cigarette packet transmission channel 203, and if so, a confirmation signal is generated and output. In the former, since the transmission of the detection signal is not performed, the time for transmitting the signal can be reduced; the latter can save power and energy because detection needs to be turned on only when the auxiliary 202 is shut down.
Further, in step S103, detecting whether there is a cigarette packet in the cigarette packet transmission channel 203 includes: whether a cigarette packet exists at a first preset position on the cigarette packet transmission channel 203 is detected. In step S104, removing the cigarette packets on the cigarette packet transmission channel 203 includes: and eliminating the detected cigarette packets on the cigarette packet transmission channel.
Specifically, the first preset position is a position on the cigarette packet conveying channel 203, which is closer to the host machine, and the position for rejecting the cigarette packet is on the downstream side of the first preset position along the conveying direction of the cigarette packet conveying channel 203 and is adjacent to the first preset position. If the tobacco bale is detected at the first preset position, after the stop signal and the confirmation signal of the tobacco bale are received, a removing signal is generated at the position where the tobacco bale is removed to remove the detected tobacco bale.
Specifically, as shown in fig. 2 and fig. 3, in this embodiment, the system of the method for improving the operation efficiency of the packing unit includes a cigarette packet detecting device 206, a controller 207, and a rejecting device 208, where the cigarette packet detecting device 206 is disposed at a first preset position, connected to the controller 207, and configured to detect whether there is a cigarette packet in the cigarette packet transmission channel 203; the rejecting device 208 is arranged on the downstream side of the cigarette packet conveying channel 203 close to the first preset position, is connected with the controller 207, and is used for rejecting cigarette packets on the cigarette packet conveying channel. Here, the downstream side refers to a direction in which the main machine 201 transmits the cigarette packet to the auxiliary machine 202 with respect to the cigarette packet transmission path 203. In step S104, the cigarette packets on the cigarette packet transmission path 203 are removed by sending a confirmation signal to the controller 207 after the cigarette packet detection device 206 detects a cigarette packet at the first preset position, sending a removal signal to the removal device 208 after the controller 207 receives the stop signal of the auxiliary machine 202 and the confirmation signal, and controlling the removal device 208 to remove the detected cigarette packet.
Further, the method for improving the operation efficiency of the packaging unit further comprises the following steps:
step S102, detecting the first time when the second preset position is shielded by the cigarette packet; the second preset position is located between the first preset position and the auxiliary machine; and comparing the first time with a first threshold time, and judging whether the first time exceeds the first threshold time.
Specifically, the second preset position is located between the position where the cigarette packet is removed and the auxiliary machine and close to one side of the auxiliary machine.
It should be noted that, step S102 may be performed before step S103, after step S103, or simultaneously with step S101 and step S103, and the cigarette packet detected at the first preset position can be rejected as long as three conditions, that is, the stop signal, the confirmation signal, and the first time exceeding the first threshold time, are met. For example, after receiving the shutdown signal of the auxiliary device 202, step S102 may be performed to determine whether the first time for blocking the cigarette packet exceeds the first threshold time, and step S103 may be performed to determine whether the confirmation signal that the cigarette packet is detected at the first preset position is received. Step S103 may be performed first, that is, after receiving the stop signal and the confirmation signal of the auxiliary 202, step S102 may be performed to determine whether the confirmation signal indicating whether the cigarette packet is detected at the first preset position is received.
Specifically, the first time that the cigarette packet is blocked is detected at the second preset position, and when the packaging unit normally operates (that is, the main machine and the auxiliary machine do not stop), if the first time exceeds a certain time, it indicates that the cigarette packet transmission channel 203 is blocked near the auxiliary machine 202, and at this time, the auxiliary machine 202 is controlled to operate at a high speed, so as to prevent the cigarette packet from blocking the main machine 201 to cause the main machine 201 to stop.
Specifically, in step S102, the first threshold time is used when the cigarette packet is jammed from the second preset position to the first preset position, or used when the cigarette packet is jammed from the second preset position to any position between positions where the cigarette packet is removed. The reason why the first threshold time is set is that a part of tobacco packets can be arranged on the tobacco packet transmission channel 203, the tobacco packets can be processed after the auxiliary machine 202 operates normally, manual addition after removal is not needed, and time and labor cost are saved. Preferably, the first threshold time is set to the time of use when the cigarette packet is just jammed at the location where the cigarette packet is removed. More specifically, the first threshold time may be 400 ± 10 ms. Preferably, the first threshold time is 400 ms.
Further, in step S104, the detected cigarette packets on the cigarette packet transmission channel 203 are removed until the removal signal is not received or the removal stopping signal is received. Because there is a certain distance between the cigarette packets transported on the cigarette packet transport path 203, in order to save energy, the removing device 208 (as shown in fig. 3) does not need to be in an open state all the time, but the removing signal can be continued for a certain time (that is, the removing device 208 is closed after being opened for a certain time), and the lasting time is the time for removing a single cigarette packet. Specifically, the duration of rejecting the cigarette packets on the cigarette packet transmission channel 203 may be 40 ± 2 ms. Preferably 40 ms.
Further, the method for improving the operation efficiency of the packaging unit further comprises step S105, after receiving the shutdown signal, recording a second time for shutdown of the auxiliary machine; and comparing the second time with a second threshold time, and stopping removing the tobacco packets on the tobacco packet transmission channel if the second time exceeds the second threshold time.
Specifically, for example, when the auxiliary device 202 needs to be replaced or needs to be stopped for a period of time due to a fault, the cigarette packet on the cigarette packet transmission channel 203 can be removed by the method, and the main machine 201 is prevented from being stopped due to the cigarette packet being blocked by the main machine 201. If the auxiliary machine 202 is stopped for a certain time, the auxiliary machine 202 is still in a stopped state, and the cigarette packet is not removed, the cigarette packet on the cigarette packet transmission channel 203 is blocked to the main machine 201, and after the main channel blockage detection device of the main machine 201 detects the cigarette packet blockage, the main machine 201 is stopped, and then the whole packing machine set stops running. Specifically, the second threshold time may be set as the case may be, for example, the second threshold time may be set to 5 min. This is because if the auxiliary machine 202 is stopped for a long time, if the tobacco bale is removed all the time, the removed tobacco bale is more, and then the removed tobacco bale is put back to the main machine 201 or the tobacco bale transmission channel 203, a long time is needed, which may reduce the effective operation efficiency of the packing machine set and waste the manpower, so when the second time that the auxiliary machine 202 is stopped exceeds the second threshold time, the tobacco bale is not removed any more.
The working principle of the method for improving the operation efficiency of the packaging unit is as follows: when the auxiliary machine 202 is stopped, after a stop signal of the auxiliary machine 202 is received, whether a tobacco bale exists at a first preset position on the tobacco bale transmission channel 203 is detected, and if the tobacco bale exists, the detected tobacco bale on the tobacco bale transmission channel 203 is removed. In order to improve the operating efficiency of the packing unit, the first time of cigarette packet blockage can be detected at the second preset position, when the first time exceeds the preset first threshold time, namely the cigarette packet blockage is detected to the position of rejecting the cigarette packet, if the cigarette packet existing at the first preset position is detected, the cigarette packet on the cigarette packet transmission channel 203 is rejected. In addition, when the second time of the halt of the auxiliary machine 202 exceeds the preset second threshold time, the tobacco packets are not removed any more, the tobacco packets are blocked to the main machine 201, and then the whole packing machine set is halted.
According to the method for improving the operation efficiency of the packing unit, when the auxiliary machine 202 is stopped, whether the first time that the second preset position is shielded by the cigarette packet exceeds the first threshold time or not is detected, whether the cigarette packet exists at the first preset position on the cigarette packet transmission channel or not is detected, if the first time exceeds the first threshold time or not, the cigarette packet exists at the first preset position, then the cigarette packet on the cigarette packet transmission channel 203 is removed, therefore, the cigarette packet cannot block the main machine 201, even if the auxiliary machine 202 is stopped, the main machine 201 can still normally operate, the number of times that the packing unit is stopped is reduced, and the work efficiency of the packing unit is improved.
Corresponding to the above method, the embodiment of the present invention discloses a system for improving the operation efficiency of a packaging machine set, as shown in fig. 2 and fig. 3, the system includes an auxiliary machine halt detection module 204, a cigarette packet detection device 206, a rejecting device 208 and a controller 207, wherein the auxiliary machine halt detection module 204 is connected with an auxiliary machine 202 for detecting whether the auxiliary machine 202 halts, and when the auxiliary machine 202 halts, a halt signal is generated and output; the cigarette packet detection device 206 is arranged at a first preset position, the first preset position is a position between the main machine 201 and the auxiliary machine 202 along the cigarette packet transmission channel 203, and is used for detecting whether a cigarette packet exists at the first preset position, and if so, the cigarette packet detection device 203 generates and outputs a confirmation signal; the controller 207 is respectively connected with the auxiliary machine halt detection module 204, the cigarette packet detection device 206 and the rejecting device 208, and is used for controlling the rejecting device 208 to reject the cigarette packets on the cigarette packet transmission channel 203 after receiving the halt signal and the confirmation signal.
Based on the system for improving the operation efficiency of the packaging unit provided by the above embodiment of the present invention, when the auxiliary machine halt detection module 204 detects that the auxiliary machine 202 halts, a halt signal is generated and transmitted to the controller 207; at this time, if the cigarette packet detecting device 206 detects that a cigarette packet exists on the cigarette packet transmission channel 203, a confirmation signal is generated and output to the controller 207, and after the controller 207 receives the stop signal and the confirmation signal, the controller 207 outputs a removing signal to the removing device 208 to control the removing device 208 to remove the cigarette packet on the cigarette packet transmission channel 203. Therefore, even if the auxiliary machine 202 is stopped, the main machine 201 and the tobacco bale transmission channel 203 still operate, but the tobacco bales on the tobacco bale transmission channel 203 are removed, so that the tobacco bales on the tobacco bale transmission channel 203 cannot block the main machine 201, the main machine 201 cannot stop operating, the stop times of the packaging machine set are reduced, and the operating efficiency of the packaging machine set is improved.
Specifically, the cigarette packet detecting device 206 detects whether a cigarette packet exists at a first preset position on the cigarette packet transmission channel 203, and may detect all the time during the operation of the packing unit, or send a detection signal to detect whether a cigarette packet exists at the first preset position after receiving a stop signal.
Further, the controller 207 is further configured to generate a detection signal after receiving the shutdown signal, and transmit the detection signal to the cigarette packet detecting device 206, so as to control the cigarette packet detecting device 206 to detect whether a cigarette packet exists at the first preset position. Specifically, when the auxiliary machine 202 is stopped, and after receiving a stop signal of the auxiliary machine 202, a detection signal is generated and output to the cigarette packet detection device 206 to detect whether a cigarette packet exists at a first preset position on the cigarette packet transmission channel 203, and if so, a confirmation signal is generated and output to the controller 207.
Further, as shown in fig. 2, in the present embodiment, the rejecting device 208 is located on the downstream side of the cigarette packet conveying channel 203 near the first preset position, and is connected to the controller 207 for rejecting the cigarette packet on the cigarette packet conveying channel. Here, the downstream side refers to a direction in which the main machine 201 transmits the cigarette packet to the auxiliary machine 202 with respect to the cigarette packet transmission path 203. Specifically, the removing device 208 comprises a compressed air power source 2081, an electromagnetic valve 2082, a removing port 2083 and a cigarette packet collecting device 2084. The air compression power source 2081 is used for providing compressed air for the rejection port 2083 when the electromagnetic valve 2082 is opened; the electromagnetic valve 2082 is connected with the controller 207, the air compression power source 2081 and the eliminating port 2083, and is used for receiving the eliminating signal sent by the controller 207 and controlling the electromagnetic valve 2082 to be opened and closed according to the eliminating signal, so as to open or close the air compression power source 2081. When the electromagnetic valve 2082 receives a rejection signal, the electromagnetic valve 2082 is opened, and the compressed air power source 2081 conveys compressed air to the rejection port 2083, so that cigarette packets on the cigarette packet transmission channel 203 opposite to the rejection port 2083 are rejected; when the solenoid valve 2082 receives the rejection stopping signal or the rejection signal for a first time exceeding a first threshold time or does not receive the rejection signal, the solenoid valve 2082 is closed. Of course, when the cigarette packet does not need to be removed, the switch of the air compression power source 2081 can be manually closed, and the whole packaging unit can be stopped if the compressed air is stopped being supplied to the removing port 2083. In addition, tobacco bale collection device 2084 sets up in tobacco bale transmission path 203 and the relative one side of eliminating mouth 2083 for collect the tobacco bale that is eliminated.
Specifically, controlling the rejecting device 208 to reject the cigarette packet on the cigarette packet transmission channel 203 means that after the cigarette packet detection device 206 detects the cigarette packet at the first preset position, the controller 207 sends a confirmation signal to the rejecting device 208, and after receiving the stop signal of the auxiliary machine 202 and the confirmation signal, the controller 207 sends a rejecting signal to the rejecting device 208, and controls the rejecting device 208 to reject the detected cigarette packet.
Specifically, the cigarette packet detection device 206 may be always turned on during the operation of the packing machine set, or the cigarette packet detection device 206 may be turned on after the controller 207 receives a stop signal of the auxiliary machine 202 and sends a detection signal to the cigarette packet detection device 206. The former can reduce the transmission of signals, so that the time for the controller 207 to generate the rejection signal can be reduced; in the latter case, the cigarette packet detection device 206 is turned on only when needed, so that power and energy can be saved.
Further, the system further comprises a cigarette packet shielding timing device 205 arranged at a second preset position, the second preset position is located on one side, close to the auxiliary machine 202, of the cigarette packet transmission channel 203, and the cigarette packet shielding timing device 205 is connected with the controller 207 and is used for detecting first time when the second preset position is shielded by a cigarette packet and outputting the first time to the controller 207; the controller 207 is further configured to compare the first time with a first threshold time after receiving the shutdown signal and the acknowledgement signal, and if the first time exceeds the first threshold time, the controller 207 controls the rejecting device 208 to reject the cigarette packet on the cigarette packet transmission channel 203. For example, the controller 207 may compare the first time with a first threshold time, and determine whether the first time exceeds the first threshold time, or may perform the determination after the controller 207 receives the shutdown signal and before the controller 207 receives the acknowledgement signal. That is, after the controller 207 receives the stop signal, if the first time exceeds the first threshold time and receives the confirmation signal, the controller 207 controls the rejecting device 208 to reject the cigarette packet on the cigarette packet conveying channel 203.
Specifically, the cigarette packet blocking timing device 205 detects a first time when the device is blocked by a cigarette packet at a second preset position, and under the condition that the packaging unit normally operates, if the first time exceeds a certain time, it indicates that the cigarette packet transmission channel 203 is blocked by the auxiliary machine 202, and at this time, the auxiliary machine 202 is controlled to operate at a high speed so as to prevent the cigarette packet from blocking the main machine 201 and causing the main machine 201 to stop.
Specifically, in this embodiment, a first threshold time is set, and the first threshold time may be used when the cigarette packet is jammed from the second preset position to the rejecting device 208, or may be used when the cigarette packet is jammed from the second preset position to any one position between the rejecting devices 208. The reason is that a part of the cigarette packets can be arranged on the cigarette packet transmission channel 203, and the cigarette packets can be processed after the auxiliary machine 202 operates normally without being added manually after being removed, so that the time and the labor cost are saved. Preferably, the first threshold time is set to the time when the cigarette packet is just jammed to the rejecting device 208. More specifically, the first threshold time may be 400 ± 10 ms. Preferably, the first threshold time is 400 ms.
In addition, in this embodiment, the cigarette packet blocking timing device 205 is configured to determine whether the cigarette packet is blocked to a position corresponding to the first threshold time. After the controller 207 receives the stop signal sent by the auxiliary machine stop detection module 204, before the cigarette packet detection device 206 detects that the cigarette packet exists in the first preset position, it may be determined whether the cigarette packet is already blocked for a certain distance, that is, after the controller 207 determines that the first time detected by the cigarette packet blocking timing device 205 exceeds the first threshold time, and when an acknowledgement signal sent by the cigarette packet detection device 206 is received, the detected cigarette packet is started to be rejected. Or after the cigarette packet detecting device 206 detects that the cigarette packet exists in the first preset position, it is determined whether the cigarette packet is blocked for a certain distance, and then the detected cigarette packet is removed.
Further, the rejecting device 208 rejects the cigarette packets on the cigarette packet transmission channel 203 after receiving the rejecting signal output by the controller 207 until receiving no rejecting signal or a rejecting stop signal. Because there is a certain distance between the tobacco bale and the tobacco bale that are transported on tobacco bale transmission path 203, in order to be able to practice thrift the energy, need not to make removing device 208 handle opening device all the time, but can make the rejection signal can last a period of time (that is removing device 208 opens and closes after a period of time), and this duration of time is the time of rejecting the single box tobacco bale. Specifically, the duration of rejecting the cigarette packets on the cigarette packet transmission channel 203 may be 40 ± 2 ms. Preferably 40 ms.
Further, the system further includes a second timing module 209, connected to the controller 207, and configured to record a second time when the auxiliary device 202 is stopped after the controller 207 receives the stop signal, and output the second time to the controller 207;
the controller 207 is further configured to compare the second time with a second threshold time, and if the second time exceeds the second threshold time, the controller 207 controls the rejecting device 208 to stop rejecting the cigarette packets on the cigarette packet transmission channel 203.
Specifically, for example, when the auxiliary device 202 needs to replace an auxiliary material or needs to be stopped for a period of time due to a fault, the rejecting device 208 can reject the cigarette packet on the cigarette packet transmission channel 203 after receiving a rejecting signal sent by the controller 207, so as to avoid the stop of the main machine 201 due to the blockage of the cigarette packet to the main machine 201. If the auxiliary machine 202 needs to be stopped for a long time after stopping for a certain time, the cigarette packet is not removed, the cigarette packet on the cigarette packet transmission channel 203 is blocked to the main machine 201, and the main machine 201 is stopped after the main channel blockage detection device of the main machine 201 detects the cigarette packet blockage, so that the whole packing machine set stops running. Specifically, the second threshold time may be set as the case may be, for example, the second threshold time may be set to 5 min. This is because if the auxiliary machine 202 is stopped for a long time, if the tobacco bale is removed all the time, the removed tobacco bale is more, and then the removed tobacco bale is put back to the main machine 201 or the tobacco bale transmission channel 203, a long time is needed, which may reduce the effective operation efficiency of the packing machine set and waste the manpower, so when the second time that the auxiliary machine 202 is stopped exceeds the second threshold time, the tobacco bale is not removed any more.
The working principle of the embodiment is as follows: when the auxiliary machine halt detection module 204 detects that the auxiliary machine 202 halts, a halt signal is generated and sent to the controller 207, after the controller 207 receives the halt signal, the cigarette packet detection device 206 is controlled to detect whether a cigarette packet exists at a first preset position on the cigarette packet transmission channel 203, if so, the cigarette packet detection device 206 generates and sends a confirmation signal to the controller 207, and after the controller 207 receives the confirmation signal, a rejection signal is generated to the rejection device 208 to reject the detected cigarette packet on the cigarette packet transmission channel 203. In order to improve the operation efficiency of the packing unit, it is also determined that the first time exceeds a preset first threshold time according to the first time that the cigarette packet is blocked by the cigarette packet blocking timing device 205 at the second preset position, that is, when the cigarette packet is detected to be blocked to the position where the cigarette packet is removed, if the cigarette packet detecting device 206 detects that the cigarette packet exists at the first preset position at this time, the cigarette packet on the cigarette packet transmission channel 203 is removed. In addition, when the second time of the halt of the auxiliary machine 202 exceeds the preset second threshold time, the tobacco packets are not removed any more, and then the whole packaging unit is halted after the tobacco packets are blocked by the main machine 201.
According to the utility model provides a system for improve packing unit operating efficiency, through when auxiliary engine 202 shuts down, whether the very first time that detects the second and predetermine the position and sheltered from by the tobacco bale exceeds first threshold value time, and whether there is the tobacco bale in the first predetermined position that detects on the tobacco bale transmission path, if the very first time exceeds first threshold value time, there is the tobacco bale in the first predetermined position, so reject the tobacco bale on the tobacco bale transmission path 203, consequently, the tobacco bale can not block up host computer 201, so even auxiliary engine 202 shuts down, host computer 201 still can normal operating, the number of times that the packing unit shut down has been reduced, the work efficiency of packing unit has been improved.
