Description

Technical Field

[0001] The invention relates to the technical field of mechanical arms, in particular to a mechanical arm device for automatically cleaning cigarette glue cylinders. Background Art

[0002] The robotic arm has multiple joints, and under the control of the controller, it can drive the end to move freely in space, so it has been widely used in industry.

[0003] When a cigarette making machine produces cigarettes, it needs to transfer the glue stored in the glue cylinder to the cigarette paper through the rotation of the rubber roller to bond the cigarettes. The cigarette making machine needs to be cleaned regularly. The glue cylinder and the rubber roller are always immersed in the glue, which makes it difficult to clean. When cleaning, it is necessary to clean the glue cylinder and the rubber roller inside it at the same time. At present, cigarette factories have begun to widely use dry ice cleaning technology to clean the glue cylinder, and at the same time cooperate with the robot arm to drive the spray gun to move flexibly, and spray dry ice particles onto the surface and grooves of the glue cylinder and the rubber roller.

[0004] After searching, the Chinese patent with publication number: CN117509144A discloses a dry ice cleaning and transportation mechanical arm device for cigarette glue cylinders. The invention sets a sliding component and a blocking component. The power provided by the first motor makes the first slider slide in the first slide groove. The power provided by the second motor drives the gear to rotate, so that the insertion rod moves up and down. When the insertion rod moves downward, the fourth slider slides in the fourth slide groove, and the baffle rotates and opens under the influence of the gravity of the collection pot. When the mechanical gripper body grabs the glue cylinder, the insertion rod moves upward. When the lower end inner wall of the fourth slide groove abuts against the fourth slider, the fourth slider is driven to move upward, so that the first transmission rod drives the baffle to close and blocks the bottom of the glue cylinder to prevent the glue cylinder from shaking with the movement of the mechanical arm, and the glue liquid in the glue cylinder from shaking to the outside of the glue cylinder, thereby causing pollution to the mechanical equipment and damage to the production environment.

[0005] Based on the above search and combined with actual problems, it is found that the existing mechanical arm device for cleaning the rubber cylinder cannot drive the rubber roller in the rubber cylinder to rotate when spraying dry ice particles, resulting in the outer surface of the rubber roller close to the bottom of the rubber cylinder cannot fully contact with the dry ice particles, thus affecting the cleaning effect, and a lot of residual glue is usually accumulated on the bottom of the rubber cylinder. Since the residual glue has a certain viscosity, the residual glue inside cannot be completely poured out by conventional pouring. The residual glue is easily covered on the inner surface of the rubber cylinder and the grooves on the surface of the rubber roller, resulting in the dry ice particles cannot completely enter the grooves on the surface of the rubber roller, further reducing the cleaning effect.

DETAILED DESCRIPTION

[0022] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described.

The rubber roller driving mechanism comprises a vertical plate 301 (such as a vertical plate 301) fixed on the conveyor belt 1.

[0024] Furthermore, the four rotating rods 102 are each provided with a slide groove 116 (such as Figure 5 As shown in the figure, both ends of the two scrapers 103 are fixed with sliders 117 slidably connected to the inner sides of the four slide grooves 116, the inner sides of the four slide grooves 116 are fixed with guide rods 118, the four sliders 117 are slidably sleeved on the outer sides of the four guide rods 118, and one end of the four sliders 117 is elastically connected to one end of the inner side of the corresponding slide groove 116 through a first spring 119; Under the guidance of the slide groove 116, the slider 117 and the scraper 103 can move linearly along the inner side of the slide groove 116. At the same time, under the elastic force of the first spring 119, a thrust is applied to the slider 117, and the thrust is transmitted to the scraper 103, so that the lower side of the scraper 103 is always in close contact with the bottom surface of the glue cylinder, thereby improving the scraping effect and ensuring that the residual glue on the bottom surface of the glue cylinder is evenly scraped to the middle position for more complete collection.

[0025] Furthermore, the glue extraction mechanism includes a glue extraction cylinder 106 and a glue storage cylinder 107 arranged outside the sealing cover 4, two cavities 104 and two glue suction channels 105 opened inside the two scrapers 103, one end of the glue storage cylinder 107 is threadedly connected to an end cap 120, the cavity 104 and the glue suction channel 105 located at the same place are connected to each other, one end of the glue extraction cylinder 106 is installed with a glue extraction cylinder 108, the telescopic end of the glue extraction cylinder 108 is fixed with a glue extraction piston 109 slidably connected to the inner side of the glue extraction cylinder 106, and one end of the glue extraction cylinder 106 is connected to the end of the glue extraction cylinder 108. The connecting pipe 110 is connected to the inner side of the glue storage cylinder 107, and one end of the glue extraction cylinder 106 is connected to a glue extraction main pipe 111, and the end of the glue extraction main pipe 111 is connected to two glue extraction branch pipes 112 through a three-way valve. The two glue extraction branch pipes 112 are respectively connected to the inside of the two cavities 104. Both the connecting pipe 110 and the glue extraction main pipe 111 are provided with a one-way valve. The conducting direction of the one-way valve inside the connecting pipe 110 points to the inside of the glue storage cylinder 107, and the conducting direction of the one-way valve inside the glue extraction main pipe 111 points to the inside of the glue extraction cylinder 106; The accumulated residual glue is extracted and collected through the glue extraction mechanism, so that the residual glue at the bottom of the glue cylinder can be quickly recovered, the accumulation of residual glue can be reduced, and the residual glue can be prevented from dripping and contaminating the glue cylinder and equipment during cleaning. At the same time, the residual glue can be prevented from covering the grooves on the surface of the glue cylinder and the rubber roller. When performing dry ice cleaning, the dry ice particles can fully enter the grooves on the surface of the glue cylinder and the rubber roller, thereby improving the cleaning effect.

[0026] Further, the shaft driving mechanism includes two worm gears 205 fixed at one end of the two shafts 101, two worms 203 symmetrically connected to one end of the outer side of the sealing cover 4, and a first motor 201 installed at one end of the outer side of the sealing cover 4, a driving bevel gear 202 is fixed to the driving end of the first motor 201, one end of the two worm gears 203 is fixed with a driven bevel gear 204 meshing with the driving bevel gear 202, and the two worm gears 203 are respectively meshed with the two worm gears 205; The two rotating shafts 101 of the scraper mechanism are driven to rotate in opposite directions by the rotating shaft driving mechanism, thereby driving the two scrapers 103 to rotate in opposite directions by the rotating rod 102. The reverse rotation of the two scrapers 103 can gather the residual glue on the bottom of the glue cylinder to the middle position, thereby facilitating the collection of the residual glue.

[0027] Further, a guide bar 113 is fixed on one side of the two scrapers 103, and a rubber pusher 115 is slidably connected to one side of the two scrapers 103 through the guide bar 113. A pusher cylinder 114 is installed on one side of the two scrapers 103, and the telescopic ends of the two pusher cylinders 114 are fixedly connected to one side of the two pushers 115 respectively. The telescopic end of the control push plate cylinder 114 is extended to drive the rubber pushing plate 115 to slide downward along one side of the scraper 103, so that the residual glue adhering to the surface of the scraper 103 can be pushed to the lower end of the glue suction channel 105 by the lower side of the rubber pushing plate 115, so that the residual glue is sucked into the cavity 104, thereby preventing excessive glue from accumulating on the surface of the scraper 103.

[0028] Furthermore, the four outer side surfaces of the sealing cover 4 are provided with positioning baffles 5, and the lower end of each positioning baffle 5 is bent outwards; A plurality of positioning baffles 5 are arranged on the outer side of the sealing cover 4, and the lower end of each positioning baffle 5 is bent outward. When the sealing cover 4 moves downward, under the guiding action of the plurality of positioning baffles 5, a lateral thrust can be applied to the rubber cylinder on the upper side of the conveyor belt 1, so that the rubber cylinder is aligned with the sealing cover 4, making it easier for the scraper mechanism to extend into the inner side of the rubber cylinder.

[0029] Furthermore, a sensor 9 is installed on the outer side of the sealing cover 4 near the mechanical arm 2, and the sensor 9 is electrically connected to the lifting cylinder 7 through a control circuit; The glue cylinder first moves to the bottom of the door frame 3. When the sensor 9 senses the glue cylinder below, the sensor 9 feeds back a signal to the lifting cylinder 7 through the control circuit. The telescopic end of the lifting cylinder 7 quickly extends to drive the sealing cover 4 to move downward.

[0030] Working principle: When in use, the AGV robot in the workshop can transport each glue cylinder of the cigarette making machine separately (hereinafter referred to as glue cylinder). The AGV robot can move along the preset track in the workshop. The AGV can transport the transported glue cylinder to the upper side of the conveyor belt 1 of the device. The conveyor belt 1 can transport several glue cylinders that need to be cleaned. The glue cylinder first moves to the bottom of the door frame 3. When the sensor 9 senses the glue cylinder below, the sensor 9 feeds back the signal to the lifting cylinder 7 through the control circuit. The telescopic end of the lifting cylinder 7 quickly extends to drive the sealing cover 4 to move downward. A plurality of positioning baffles 5 are arranged on the outside, and the lower end of each positioning baffle 5 is bent outward, so under the guiding action of the plurality of positioning baffles 5, a lateral thrust can be applied to the rubber cylinder on the upper side of the conveyor belt 1, so that the rubber cylinder is aligned with the sealing cover 4, and at the same time, when the sealing cover 4 moves down to contact the rubber cylinder, it just covers the upper side of the rubber cylinder to seal the rubber cylinder. At this time, the rubber cylinder is blocked by the sealing cover 4 and the positioning baffles 5 and does not move, and its lower side only slides with the belt of the conveyor belt 1. The sealing cover 4 seals the rubber cylinder, which can prevent the residual glue inside the rubber cylinder from overflowing, thereby preventing the equipment from being polluted, thereby ensuring the cleanliness of the equipment surface; After the sealing cover 4 is sealed with the glue cylinder, the lower sides of the two scrapers 103 of the glue scraping mechanism just contact the two side edges of the bottom surface of the glue cylinder, and then the first motor 201 of the shaft driving mechanism runs to drive the active bevel gear 202 to rotate, and the active bevel gear 202 drives the two driven bevel gears 204 to rotate in the opposite direction through the teeth, and the two driven bevel gears 204 respectively drive the two worm gears 203 to rotate in the opposite direction, and the two worm gears 203 respectively drive the two worm wheels 205 to rotate in the opposite direction, thereby driving the two rotating shafts 101 of the glue scraping mechanism to rotate in the opposite direction, and the two rotating shafts 101 of the glue scraping mechanism respectively drive the four rotating rods 102 on both sides to rotate in the opposite direction, and the four rotating rods 102 respectively drive the two scrapers 103 to rotate in the opposite direction, so that the two scrapers 103 rotate synchronously to the middle position, and when the two scrapers 103 rotate, their lower sides slide along the bottom surface of the glue cylinder, and when the lower sides of the two scrapers 103 are completely rotated to the middle position of the bottom surface of the glue cylinder (such as Figure 6 As shown in the figure, at this time, the two scrapers 103 can gather the residual glue on the bottom of the glue cylinder to the middle section of the bottom of the glue cylinder, so as to gather the scattered glue and collect the glue. Under the guidance of the slide groove 116, the slider 117 and the scraper 103 can move linearly along the inner side of the slide groove 116. At the same time, under the elastic force of the first spring 119, a thrust is applied to the slider 117, and the thrust is transmitted to the scraper 103, so that the lower side of the scraper 103 is always in close contact with the bottom of the glue cylinder, thereby improving the scraping effect and ensuring that the residual glue on the bottom of the glue cylinder is evenly scraped to the middle section, so as to be more fully collected. Then, the telescopic end of the glue extraction cylinder 108 of the glue extraction mechanism is controlled to retract and drive the glue extraction piston 109 to move, so that a negative pressure state is formed inside the glue extraction cylinder 106, so that the gathered glue is sucked into the inner sides of the two cavities 104 through the two glue suction flow channels 105, and then sucked into the inner side of the glue extraction cylinder 106 through the glue extraction branch pipe 112, the three-way valve, and the glue extraction main pipe 111. When the telescopic end of the glue extraction cylinder 108 is fully retracted, it is extended again, driving the glue extraction piston 109 to move in the opposite direction to squeeze the glue sucked into the inner side of the glue extraction cylinder 106 through the connecting pipe 110 to the inner side of the glue storage cylinder 107, thereby realizing rapid recovery of the residual glue at the bottom of the glue cylinder, reducing the accumulation of residual glue, preventing the residual glue from dripping and contaminating the glue cylinder and equipment during cleaning, and preventing the residual glue from covering the grooves on the surfaces of the glue cylinder and the rubber roller. When performing dry ice cleaning, the dry ice particles can fully enter the grooves on the surfaces of the glue cylinder and the rubber roller, thereby improving the cleaning effect; After the residual glue on the bottom of the glue cylinder is collected, the telescopic end of the lifting electric cylinder 7 drives the sealing cover 4 to move upward and reset, so that the sealing cover 4 is separated from the glue cylinder, and the multiple positioning baffles 5 are also separated from the glue cylinder. The glue cylinder continues to move to the position of the mechanical arm 2 under the traction of the conveyor belt 1. The dry ice cleaning machine 6 can generate dry ice particles and spray the dry ice particles through the dry ice spray gun 8. At the same time, through the action of the mechanical arm 2, the mechanical arm 2 can drive the dry ice spray gun 8 to move flexibly above the glue cylinder, so that the dry ice particles are evenly sprayed onto the surface of the glue cylinder and the rubber roller. The dry ice particles quickly sublimate on the surface of the glue cylinder and the rubber roller and in the groove to form carbon dioxide gas. During the sublimation process of the dry ice, a large amount of heat is absorbed and expanded hundreds of times at the same time, so that the residual glue on the surface of the glue cylinder and the rubber roller and in the groove is quickly cooled, thereby generating brittle cracks, so that it is easy to fall off from the surface of the glue cylinder and the rubber roller. At the same time, the sublimation and expansion of the dry ice into a gaseous state will generate a high-speed airflow to blow out the fallen glue, thereby achieving a quick cleaning effect; When the glue cylinder passes the position of the robot arm 2, one end of the rubber roller inside it will contact the lower side of the driving wheel 306 of the rubber roller driving mechanism, and the second motor 305 will keep running to drive the driving wheel 306 to rotate, and the second spring 304 can apply a downward thrust to the slide plate 303, and the thrust is transmitted to the driving wheel 306, so that the driving wheel 306 can be pressed on the upper side of the rubber roller. When the driving wheel 306 rotates, the rubber roller can be driven to rotate by friction, so that each position of the outer surface of the rubber roller can fully contact the dry ice particles, thereby further improving the cleaning effect of the glue cylinder and the rubber roller.
