Description

Technical Field

[0001] This utility model belongs to the field of tobacco machinery technology, specifically relating to a tobacco stick anti-sticking device. Background Technology

[0002] The packaging process for cigarette packs using the FOCKE408 packaging machine includes the following steps: The cigarette packs are pushed into the output rail by the rotary wheel II ejector. The folding plow at the output rail inlet folds the second side fold and the first end fold. Pre-sealing irons on both sides of the output rail pre-seal the first end fold of the film (cigarette pack wrapping paper). Sensors at the output rail detect the cigarette packs output from rotary wheel II; if a defective pack is detected, it is discharged from the outlet. Qualified cigarette packs are fed into the output tower by the elevator, where the upper fold of the film end is folded. The hot-sealing irons inside the output tower complete the final hot-sealing of the film. When the cigarette pack reaches the top of the output tower, it is discharged by the horizontal output mechanism.

[0003] When the FOCKE408 packaging machine is stopped for an extended period or idles for too long, the cam-linkage mechanism detaches the hot-sealing iron from both ends of the cigarette pack. However, the hot-sealing iron's center temperature is 150 degrees Celsius, and even after detaching from the cigarette pack surface, it remains relatively close to the surface. Therefore, after the packaging machine stops or idles for a certain period, the temperature of the cellophane at both ends of the cigarette pack becomes high, and this heat is conducted to the upper and lower surfaces of the cellophane. During the unfolding, folding, and conveying process, static electricity accumulates on the surface of the cellophane roll. Under the influence of static electricity and heat, the cellophane can thermally fuse and stick together between the cigarette pack's cells.

[0004] The hot-melt adhesion of the cigarette pack's transparent paper will cause the following problems: During the lateral output mechanism's pushing process, the adhered transparent paper will be forcibly torn apart, resulting in quality defects such as unclean adhered surfaces and damaged transparent paper. It may even cause the cigarette pack underneath to tilt. If the lateral conveyor push rod collides with this tilted cigarette pack during its return stroke, it will cause the packaging machine to block and stop. Because the push rod needs to overcome the adhesive force and friction between the transparent paper during the pushing process, the hot-melt adhesion of the transparent paper may cause localized deformation at the contact point between the cigarette pack and the push rod.

[0005] Because the cigarette sticks in the output tower are stacked vertically, it's impossible for operators to visually determine if they are clogged. Instead, when the equipment is idle for extended periods, operators manually push the cigarette sticks upwards one by one to check for sticking. Alternatively, while the equipment is running, operators observe the pushing of the topmost cigarette stick; if any are found to be misaligned or tilted, the machine is immediately stopped using the stop button, and the defective cigarette stick is manually removed and repackaged in transparent paper. These operations reduce equipment efficiency, require operators to monitor operation, and increase the workload for machine operators.

[0006] This application is submitted in order to address the above issues. Utility Model Content

[0014] The compressed air source 18 is connected to the ventilation slot of the air chamber cover 2 and blows compressed gas into the tobacco stick output tower 16 through the through hole to cool the transparent paper of the tobacco stick.

[0015] The proximity switch 19 is located at the top of the cigarette bar output tower 16 and is used to determine whether the cigarette bar is operating normally based on the high-level interval of the proximity switch 19.

[0016] The output tower left side plate 13 or the output tower right side plate 14 is provided with a cigarette stick adhesion detection mechanism.

[0017] The cigarette stick adhesion detection mechanism includes: a motor 9, a connecting plate 5, and a push plate 3;

[0018] The connecting plate 5 and the push plate 3 are arranged parallel to the left side plate 13 of the output tower, and a flexible piezoelectric sensor 21 is provided between the connecting plate 5 and the push plate 3.

[0019] The motor 9 is configured to drive the connecting plate 5 to move back and forth.

[0020] The push plate 3 is provided with a screw 8, and the screw 8 passes through the through hole on the connecting plate 5, so that the push plate 3 can move back and forth relative to the connecting plate 5 along the direction of the screw 8;

[0021] A spring 4 is provided on the screw 8 between the push plate 3 and the connecting plate 5;

[0022] The controller 20 is configured to receive the signal from the proximity switch 19 and control the pulsed DC electrostatic eliminator 1, the compressed air source 18, the flexible piezoelectric sensor 21, and the motor 9.

[0023] The cigarette pack adhesion detection mechanism further includes an alarm, which is communicatively connected to the flexible piezoelectric sensor 21 to issue an alarm when cigarette pack adhesion occurs.

[0024] Spring 4 can be installed through the screw 8. Both ends of spring 4 can abut against the push plate 3 and the connecting plate 5 respectively, to provide damping when the push plate 3 and the connecting plate 5 move together. One or both ends of spring 4 can also be connected to the push plate 3 and the connecting plate 5 respectively by snap-fit ​​or other means to fix the position of spring 4.

[0025] Preferably, the motor 9 is connected to a shaft 10, and a bushing 12 is connected to the connecting plate 5. The bushing 12 is nested on the shaft 10 and slidably connected to support the horizontal movement of the connecting plate 5.

[0026] Preferably, the anti-sticking device for cigarette sticks further includes: a solenoid valve for controlling the compressed air source 18 to supply air to the air chamber cover 2.

[0027] Preferably, the connecting plate 5 has a groove on its front side, the push plate 3 has a protrusion on its rear side, the flexible piezoelectric sensor 21 is disposed in the groove, and the protrusion is configured to enter the groove to squeeze the flexible piezoelectric sensor 21.

[0028] Preferably, a soldering iron 17 and a gas chamber cover 2 are provided on both the left side plate 13 and the right side plate 14 of the output tower.

[0029] A second aspect of this application provides a method for preventing cigarette sticks from sticking together. The method uses the apparatus described in the first aspect and includes the following steps:

[0030] When the high-level interval of the proximity switch 19 is less than the set value, the controller 20 defaults to the normal operation of the packaging machine, and the pulse DC static eliminator 1 is always in working state to neutralize the static electricity on the surface of the transparent paper of the cigarette stick in the cigarette stick output tower 16.

[0031] When the high-level interval of the proximity switch 19 is greater than the set value, the controller 20 controls the pulse DC electrostatic eliminator 1 to be in standby mode, and the controller 20 controls the compressed air source 18 to blow away the high-temperature gas on the surface of the soldering iron 17 to prevent the heat from concentrating and being conducted to the surface of the cigarette in the cigarette output tower 16, and wait for the equipment to run normally.

[0032] When the packaging equipment is running normally, as soon as the proximity switch 19 sends a high-level signal, the controller 20 shuts off the compressed air source 18, and the motor 9 drives the connecting plate 5 to move forward. At this time, the connecting plate 5 pushes the pusher plate 3 forward by compressing the spring 4 to push the tobacco stick in the tobacco stick output tower 16. During the process of the pusher plate 3 pushing the end face of the tobacco stick in the tobacco stick output tower 16, the pusher plate 3 contacts and squeezes the flexible piezoelectric sensor 21 with the connecting plate 5. The flexible piezoelectric sensor 21 converts the pressure into an electrical signal and transmits it to the controller 20. The controller 20 determines whether the tobacco stick sticks to the lower tobacco stick during the process of being pushed by the magnitude of the electrical signal value.

[0033] If the pressure exceeds the specified value, the motor 9 drives the connecting plate 5 to return, the controller 20 controls the packaging machine to stop, and controls the alarm to sound an alarm indicating that the cigarette sticks are stuck together.

[0034] If the pressure does not exceed the specified value, the motor 9 drives the connecting plate 5 to return to its original position, waiting for the next cycle.

[0035] Preferably, the high-level interval time is set to 10 seconds.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. This application provides a cigarette stick anti-sticking device and method. When the packaging machine is running normally, a pulsed DC static eliminator is used to neutralize the static electricity accumulated on the surface of the cigarette stick transparent paper, thereby reducing the risk of cigarette stick surface sticking during normal operation.

[0038] 2. When the packaging machine is stopped or in standby mode, in order to reduce the heat conduction of the hot soldering iron to the surface of the cigarette strip, compressed air is blown onto the surface of the cigarette strip to cool it down and reduce the risk of heat melting and sticking between the transparent paper of the cigarette strip.

When the packaging machine restarts after a period of shutdown or standby, a flexible piezoelectric sensor is used to monitor the thrust during the misalignment of the cigarette strips, detect whether the cigarette strips stick together, and issue an alarm and stop the machine when the cigarette strips stick together.

[0053] This utility model provides a cigarette stick anti-sticking device for the FOCKE408 packaging machine, mainly used to solve the equipment downtime and cigarette stick appearance defects caused by cigarette stick sticking in the output tower, thereby improving equipment operating efficiency and enhancing equipment reliability. Of course, the cigarette stick anti-sticking device of this application can also be used in other types of packaging machines.

[0054] like Figure 1-2 As shown, the FOCKE408 packaging machine's anti-sticking device for cigarette packs mainly includes a motor 9, a connecting plate 5, a solenoid valve, an air chamber cover 2, a spring 4, a pulsed DC static eliminator 1, a flexible piezoelectric sensor 21, a bushing 10, a shaft 10, a controller 20, a proximity switch 19, etc.

[0055] Figure 1 The direction of the middle arrow indicates the direction of the smoke bar conveying. The smoke bar enters the smoke bar output tower 16 horizontally from the output rail between the base plate 22 and the output rail cover plate 15.

[0056] Among them, motor 9 is a linear stepper motor. The linear stepper motor is fixed to the outside of the right side plate 14 of the output tower by countersunk bolts 6. The threaded rod of the linear stepper motor is used to cooperate with the internal threaded tube 12. The outer cylinder of the other end of the internal threaded tube 12 is interference-fitted with the countersunk hole in the middle of the connecting plate 5 so that the linear stepper motor can drive the connecting plate 5 to move back and forth.

[0057] One end of shaft 10 is equipped with a screw, which is fixedly connected to the threaded hole of the right side plate 14 of the output tower. The other end of shaft 10 is suspended for the use of bushing 11. Bushing 11 is nested on shaft 10 so that it can slide back and forth under the action of connecting plate 5. The other end of bushing 11 is fixedly connected to the bolt holes on both sides of connecting plate 5.

[0058] Multiple combinations of shaft 10 and bushing 11 can be provided and distributed at the four corners of the connecting plate 5 to provide balance and support for the connecting plate 5.

[0059] The flexible piezoelectric sensor 21 is fixed in the groove at the center of the front of the connecting plate 5. A protrusion is provided on the rear of the push plate 3 to match the groove at the center of the front of the connecting plate 5.

[0060] One end of the screw 8 is fixed to the push plate 3 by bolts, and the other end passes through the spring and the through hole on the connecting plate 5, and is fixed in position by a nut. The screw 8 can move back and forth within the through hole on the connecting plate 5, and when moving forward, it is limited by the nut to prevent the screw 8 from coming out of the through hole. For example, the through hole on the connecting plate 5 is larger than the outer diameter of the screw 8. In this way, the push plate 3 can move back and forth relative to the connecting plate 5 along the direction of the screw 8.

[0061] The pulsed DC static eliminator 1 is fixed to the cover plate 15 on the output rail via a mounting plate. The horizontal distance between the pulsed DC static eliminator 1 and the surface of the tobacco stick inside the tobacco stick output tower 16 is 30mm.

[0062] The gas chamber cover 2 is fixed to the left side plate 13 of the output tower by bolts, and sealant is applied around the connection.

[0063] The air chamber cover 2 is provided with a ventilation slot, and the left side plate 13 of the output tower is provided with a through hole communicating with the ventilation slot. The compressed air source 18 is connected to the ventilation slot of the air chamber cover 2 and blows compressed gas into the tobacco stick output tower 16 through the through hole to cool the transparent paper of the tobacco stick. The on / off state of the compressed air source 18 is controlled by a solenoid valve.

[0064] Specifically, the center of the groove in the middle of the gas chamber cover 2 is directly opposite a row of 2mm through holes on the left side plate 13 of the output tower. The through holes are at a 30-degree angle to the side plate and are positioned slightly above the middle of the ironing iron 17 for ironing the tobacco strip. The proximity switch 19 is installed at the middle of the highest point of the tobacco strip on the tobacco strip output tower 16.

[0065] The device of this application can reduce the occurrence of cigarette sticking in a variety of situations:

[0066] 1. When the high-level interval of proximity switch 19 is less than the default value of 10s, controller 20 defaults to normal operation of the packaging machine. Pulse DC static eliminator 1 is always in working state to neutralize the static electricity on the surface of the transparent paper, thereby neutralizing the static electricity accumulated on the surface of the cigarette pack transparent paper and reducing the occurrence of cigarette pack sticking.

[0067] 2. When the high-level interval of proximity switch 19 is greater than the default setting of 10 seconds, controller 20 controls pulsed DC electrostatic eliminator 1 to enter standby mode. If the high-level interval exceeds 1.0 minute, for example, due to other reasons causing the packaging machine to stop or enter standby mode, controller 20 controls the solenoid valve to activate, causing the air chamber cover 2 to connect to the compressed air source 18, which disperses the high-temperature gas on the surface of soldering iron 17, preventing heat from concentrating and being conducted to the surface of the cigarette stick, thus reducing the occurrence of cigarette stick sticking.

[0068] If the high-level interval does not exceed 1.0 min and the packaging equipment is operating normally, then it is assumed that the short downtime or standby time of the packaging machine means that the risk of cigarette sticking is small, and the above-mentioned blowing operation is not necessary.

[0069] Once the packaging equipment is running normally, check whether the cigarette packs have stuck together using the following method:

[0070] As soon as proximity switch 19 sends a high-level signal, the solenoid valve cuts off the compressed air, and the linear stepper motor screw drives the internal thread tube to move linearly, thereby driving the connecting plate to move. The connecting plate pushes the push plate forward by 4mm through the compression spring. During the process of pushing the end face of the cigarette strip, the rear end protrusion of the push plate 3 contacts the groove of the connecting plate 5, squeezing the flexible piezoelectric sensor 21.

[0071] The flexible piezoelectric sensor 21 converts the pressure signal into an electrical signal. The controller 20 determines whether the cigarette stick sticks to the lower cigarette stick during the pushing process based on the magnitude of the electrical signal value.

[0072] If the pressure exceeds the specified value, the linear stepper motor screw drives the internal threaded tube to quickly return linearly, activating the manual stop button program of the packaging machine. The packaging machine is in a stopped state, and the alarm is activated for 10 seconds to remind the operator that the cigarette sticks are severely stuck to the surface and need to be handled by the operator.

[0073] If the pressure does not exceed the specified value, the linear stepper motor screw drives the internal thread tube to quickly return in a linear motion, and the linear stepper motor waits for the next cycle.

[0074] Preferably, when the thrust does not exceed the specified value, the internal threaded tube can be driven by a linear stepper motor screw rod to push it multiple times for testing.

[0075] The above-mentioned values ​​represent the maximum pressure required for the cigarette sticks to not stick together. If the pressure exceeds the specified value, it indicates that the cigarette sticks have stuck together; if the pressure does not exceed the specified value, it indicates that the cigarette sticks have not stuck together.

[0076] In summary, the device of this application can also detect whether cigarette sticks stick together during normal operation after the packaging machine has stopped or is in standby mode, and take timely measures to resolve the issue.

[0077] During shift handover or when the packaging machine is stopped, the pulsed DC static eliminator 1 is in standby mode, the compressed air source 18 is cut off by the solenoid valve, and the motor 9 is in the initial position.
