Description

Technical Field

[0001] This invention relates to the field of cigarette production technology, and in particular to a cigarette pack rejection device. Background Technology

[0002] Currently, the GDX1 and FOCKE350S packaging machines have almost no inspection system from the carton transparent paper packaging machine to the end of the cigarette pack elevator. To avoid continuous defects in carton appearance, transparent paper, and pull lines that are not discovered until the case packing machine, resulting in a large number of defective cigarette packs remaining in the cigarette pack elevator channel, devices that utilize local appearance for quality inspection are now being installed. These devices include pull line overlap detection devices, cigarette pack side transparent paper folding defect detection devices, carton paper damage detection devices, and cigarette pack missing pack detection devices. When the detection system detects a problem, it will alarm and stop the machine, prompting the operator to check the defective cigarette packs. Frequent shutdowns of the carton paper packaging machine may also cause shutdowns of the small pack transparent paper packaging machine and the small box packaging machine. After the equipment restarts, several packs of cigarettes will be rejected to prevent the small pack label paper from not sticking or the transparent paper surface from being deformed by heat ironing. Therefore, it is necessary to reject defective cigarette packs, which will not affect the shutdown of the packaging machine.

[0003] Therefore, there is an urgent need for a cigarette stick rejection device. Summary of the Invention

[0004] The purpose of this invention is to provide a cigarette stick rejection device to solve the problems in the prior art, which can reject defective cigarette sticks without stopping the equipment, and can also be used as a sampling device.

[0005] This invention provides a cigarette strip rejection device, comprising:

[0006] The system comprises a 90-degree rotating electromagnet, a bracket, a connecting seat, a non-powered roller assembly, an air nozzle, a fiber optic sensor, a solenoid valve, and a controller. One end of the bracket is mounted on the tobacco stick conveying channel, and the other end of the bracket is connected to the 90-degree rotating electromagnet. The 90-degree rotating electromagnet is connected to the connecting seat, which is mounted on the non-powered roller assembly. The fiber optic sensor is located on the right side of the tobacco stick conveying channel. The air nozzle is positioned above the tobacco sticks conveyed on the non-powered roller assembly. The fiber optic sensor is connected to the input terminal of the controller. The 90-degree rotating electromagnet, the air nozzle, and the solenoid valve are connected to the output terminal of the controller.

[0007] In the cigarette stick rejection device described above, preferably, one end of the bracket is welded to the support plate of the cigarette stick conveying channel.

[0008] In the cigarette stick removal device described above, preferably, the other end of the bracket is connected to the 90-degree rotating electromagnet by two bolts arranged in a vertical direction.

[0009] In the cigarette bar removal device described above, preferably, the 90-degree rotating electromagnet and the connecting seat are connected by a keyway.

[0010] In the cigarette stick removal device described above, preferably, the 90-degree rotating electromagnet includes a horizontal part and a vertical part, the other end of the bracket is connected to one side of the vertical part of the 90-degree rotating electromagnet, and the other side of the vertical part of the 90-degree rotating electromagnet is connected to the connecting seat.

[0011] In the cigarette strip removal device described above, preferably, the unpowered roller assembly includes two parallel horizontal plates, a support shaft disposed between the two horizontal plates, and multiple sets of unpowered rollers disposed on the two horizontal plates in parallel, with the connecting seat disposed in the middle of the support shaft of the unpowered roller assembly.

[0012] In the cigarette stick removal device described above, preferably, there are two support shafts, and the connecting seat and the two support shafts are connected by fastening bolts.

[0013] In the cigarette stick rejection device described above, preferably, the fiber optic sensor is fixed to the support plate on the right side of the cigarette stick conveying channel via a threaded joint.

[0014] In the cigarette stick removal device described above, preferably, the cigarette stick removal device further includes a plastic bamboo tube, one side of which is connected to the air nozzle and the other side is connected to the solenoid valve.

[0015] In the cigarette stick rejection device described above, preferably, the number of air nozzles is two, and the line connecting the two air nozzles is perpendicular to the conveying direction of the cigarette sticks on the cigarette stick conveying line.

[0016] This invention provides a cigarette pack rejection device. A fiber optic sensor determines whether a defective cigarette pack has reached the rejection position. Once the cigarette pack reaches the rejection position, a controller controls a 90-degree rotating electromagnet to rotate 90 degrees clockwise, causing the connecting seat to rotate 90 degrees clockwise, which in turn drives the unpowered roller assembly to rotate. Simultaneously, a solenoid valve is activated, causing compressed air to apply pressure to the surface of the cigarette pack through the nozzle, causing the cigarette pack to quickly fall into the receiving box below the rejection port. After rejection, the device quickly returns to its original position, ensuring the normal transport of subsequent cigarette packs. This device can reject defective cigarette packs without shutting down the machine and can also be used as a sampling device. Furthermore, it can reject specific cigarette packs according to the requirements of external testing equipment, or perform automatic counting or timing sampling functions, avoiding frequent shutdowns of the cigarette packing machine or secondary impact damage to the cigarette packs from the pusher rejection device.

[0030] All terms used in this disclosure (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this disclosure pertains, unless otherwise specifically defined. It should also be understood that terms defined in a general dictionary, such as a dictionary, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0031] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0032] Currently, the main rejection devices for cigarette cartons are cylinder rejection devices and compressed air rejection devices. Cylinder rejection devices mainly use a solenoid valve to control the extension and retraction of a cylinder to quickly push defective cigarette cartons out of the conveying channel. Compressed air rejection devices have a high-pressure injection port on one side of the cigarette carton channel, using compressed air with a certain pressure to blow the cigarette cartons out of the conveying channel. Both require an opening on the other side of the channel. If the rejection opening is too wide, the cigarette cartons may deviate from the opening and get stuck at the entrance, causing blockage of subsequent cigarette cartons. If the rejection opening is too small, the cigarette cartons cannot be rejected, and loose cigarette cartons will also be unable to be rejected.

[0033] like Figures 1-3 As shown, the cigarette stick rejection device provided in this embodiment includes: a 90-degree rotating electromagnet 1, a bracket 2, a connecting seat 3, a non-powered roller assembly 4, an air nozzle 5, an optical fiber sensor 6, a solenoid valve, and a controller (not shown). One end of the bracket 2 is disposed on the cigarette stick conveying channel, and the other end of the bracket 2 is connected to the 90-degree rotating electromagnet 1. The 90-degree rotating electromagnet 1 is connected to the connecting seat 3, and the connecting seat 3 is disposed on the non-powered roller assembly 4. The optical fiber sensor 6 is disposed on the right side of the cigarette stick conveying channel. The air nozzle 5 is disposed above the cigarette stick 9 conveyed on the non-powered roller assembly 4. The optical fiber sensor 6 is connected to the input end of the controller, and the 90-degree rotating electromagnet 1, the air nozzle 5, and the solenoid valve are connected to the output end of the controller.

[0034] The cigarette stick rejection device of the present invention is located between the outlet of the cigarette box packaging machine and the inlet of the cigarette stick elevator. The controller can control the 90-degree rotating electromagnet 1, the solenoid valve, and receive rejection signal commands from other detection devices. The solenoid valve can control the on / off of compressed air.

[0035] Furthermore, one end of the bracket 2 is welded to the support plate of the cigarette conveying channel. The other end of the bracket 2 is connected to the 90-degree rotating electromagnet 1 by two bolts 7 arranged in the vertical direction.

[0036] Furthermore, the 90-degree rotating electromagnet 1 and the connecting seat 3 are connected by a keyway.

[0037] Furthermore, the fiber optic sensor 6 is fixed to the support plate on the right side of the cigarette pack conveying channel via a threaded connection. In a specific implementation, the fiber optic sensor 6 is connected to the controller via an amplifier.

[0038] During operation, the cigarette stick quality inspection device detects the quality of the cigarette sticks. If a defective cigarette stick is detected, the device transmits a defect signal (e.g., cigarette stick transparent paper detection signal, cigarette stick deformation detection signal, and sampling device signal) to the controller. At this time, the controller determines whether the defective cigarette stick has reached the rejection position based on the signal fed back by the fiber optic sensor 6. If the controller receives a high-level signal from the fiber optic sensor, it indicates that the defective cigarette stick has reached the designated rejection position. The controller controls the 90-degree rotating electromagnet 1 to rotate 90 degrees clockwise, which drives the connecting seat 3 to rotate 90 degrees clockwise, thereby driving the unpowered roller assembly 4 to rotate. At the same time, the controller controls the solenoid valve to activate, so that compressed air applies a certain pressure to the upper surface of the cigarette stick 9 through the nozzle 5, increasing the descent speed of the cigarette stick 9, causing it to leave the conveying channel and quickly fall into the receiving box below the rejection port, preventing the cigarette stick 9 from sliding along the unpowered roller assembly 4 and increasing the rejection time. After the 90-degree rotating electromagnet 1 rotates 90 degrees to its position, the controller controls the 90-degree rotating electromagnet 1 to immediately return to its initial state. At the same time, the controller controls the solenoid valve to cut off the gas supply, ensuring that the subsequent tobacco sticks move normally on the unpowered roller assembly 4 towards the tobacco stick lifter.

[0039] Therefore, compared with the prior art, the cigarette stick rejection device provided in this embodiment uses a fiber optic sensor to determine whether a defective cigarette stick has reached the rejection position. After the cigarette stick reaches the rejection position, the controller controls the 90-degree rotating electromagnet to rotate 90 degrees clockwise, which drives the connecting seat to rotate 90 degrees clockwise, thereby driving the unpowered roller assembly to rotate. At the same time, the controller controls the solenoid valve to apply pressure to the surface of the cigarette stick through the jet nozzle, causing the cigarette stick to fall quickly into the receiving box below the rejection port and return to its original position quickly after rejection, ensuring the normal conveying of subsequent cigarette sticks. It can reject defective cigarette sticks without stopping the equipment and can also be used as a sampling device. At the same time, it can reject a specific cigarette stick according to the requirements of external detection equipment, or complete the function of automatic counting or timing sampling, avoiding frequent shutdowns of the cigarette packaging machine or secondary impact damage to the cigarette stick by the push rod rejection device.

[0040] Furthermore, the cigarette stick removal device also includes a plastic bamboo-joint tube (not shown), one side of which is connected to the air nozzle 5, and the other side is connected to the solenoid valve. In this invention, the plastic bamboo-joint tube facilitates the arrangement of the air nozzle 5 and the solenoid valve, and also facilitates the adjustment of the position of the air nozzle 5.

[0041] Furthermore, such as Figure 2 As shown, the 90-degree rotating electromagnet 1 includes a horizontal part 11 and a vertical part 12. The other end of the bracket 2 is connected to one side of the vertical part 12 of the 90-degree rotating electromagnet 1, and the other side of the vertical part 12 of the 90-degree rotating electromagnet 1 is connected to the connecting seat 3.

[0042] Furthermore, such as Figure 3 As shown, the non-powered roller assembly 4 includes two parallel horizontal plates 41, a support shaft 42 disposed between the two horizontal plates 41, and multiple sets of non-powered rollers 43 arranged in parallel on the two horizontal plates 41. The connecting seat 3 is disposed in the middle of the support shaft 42 of the non-powered roller assembly 4. The cigarette stick 9 slides on the non-powered roller 43. Specifically, the overall length of the non-powered roller assembly 4 is 1.2-1.3 times the width of the cigarette stick, for example, 1.25 times, to prevent loose cigarette sticks or poorly wrapped cigarette sticks from being unable to be removed.

[0043] Furthermore, there are two support shafts 42, and the connecting seat 3 and the two support shafts 42 are connected by fastening bolts 8 respectively.

[0044] Furthermore, the number of the air nozzles 5 is two, and the line connecting the two air nozzles 5 is perpendicular to the conveying direction of the tobacco stick 9 on the tobacco stick conveyor line. In one embodiment of the invention, the distance between the two air nozzles 5 and the upper surface of the tobacco stick 9 is 28mm-32mm, for example, 30mm.

[0045] The cigarette pack rejection device provided in this embodiment of the invention uses a fiber optic sensor to determine whether a defective cigarette pack has reached the rejection position. After the cigarette pack reaches the rejection position, the controller controls a 90-degree rotating electromagnet to rotate 90 degrees clockwise, which in turn drives the connecting seat to rotate 90 degrees clockwise, thereby driving the unpowered roller assembly to rotate. At the same time, the controller controls the solenoid valve to apply pressure to the surface of the cigarette pack through the jet nozzle, causing the cigarette pack to fall quickly into the receiving box below the rejection port and return to its original position quickly after rejection, ensuring the normal conveying of subsequent cigarette packs. It can reject defective cigarette packs without stopping the equipment and can also be used as a sampling device. In addition, it can reject a specific cigarette pack according to the requirements of external detection equipment, or complete the function of automatic counting or timing sampling, avoiding frequent shutdowns of the cigarette packing machine or secondary impact damage to the cigarette packs by the push rod rejection device.

[0046] The embodiments of this disclosure have now been described in detail. To avoid obscuring the concept of this disclosure, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0047] While specific embodiments of this disclosure have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of this disclosure. Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this disclosure.
