Description

Technical Field

[0001] The invention belongs to the technical field of cement bag packaging, and relates to a fully automatic packaging production line for cement bags. Background Art

[0002] When packing and transporting cement bags, due to the characteristics of the cement bags themselves, the cement bags are heavy and prone to slipping after being stacked. In addition, the stacked cement bags are difficult to grasp and are prone to the risk of loosening and falling during movement.

[0003] For example, the Chinese patent application [application publication number: CN106428771A] discloses a production line for stacking bagged goods, including a transport channel, one end of the transport channel is an entrance end, and the other end is an exit end, the exit end of the transport channel is provided with a double-door device that can allow the bagged goods to fall sequentially, and a transfer track 1 and a transfer track 2 are provided in parallel and spaced apart below the double-door device, a transfer trolley 1 that can move back and forth along the length direction of the transfer track 1 is provided on the transfer track 1, and a transfer trolley 2 that can move back and forth along the length direction of the transfer track 2 is provided on the transfer track 2, and a moving track perpendicular to the length direction of the transfer track 1 and / or the transfer track 2 is also provided below the double-door device, and the transfer track 1 and the transfer track 2 are arranged on the moving track and can move back and forth along the length direction of the moving track.

[0004] The above structure is used to stack bagged goods such as cement bags. After stacking, the bagged goods are moved out by moving the rail parts. However, when the stacked cement bags are transported, the stacked cement bags are not neatly stacked. In the existing method, a packing cloth is laid on the stacking trolley, and the cement bags are stacked on the packing cloth. After the stacking is completed, the staff then ties the two ends of the packing cloth. A lifting ring can be provided at both ends of the packing cloth, and the lifting ring is hung on the hoist on the existing truss. The mobile hoist can drive the packing cloth to move and transport it to the truck. The manual packing method is adopted, and the cement bags are not stably tied, resulting in the risk of the cement bags slipping during transportation, which reduces the packing efficiency and packing effect of the cement bags. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a fully automatic packaging production line for cement bags. The technical problem to be solved by the present invention is: how to solve the problem that the packaging and transportation efficiency of existing cement bags is low and they are easy to loosen and fall during transportation.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A fully automatic packaging production line for cement bags, comprising a waste detection and recovery device, a steering device, a whole bag device, a packaging film packaging device and a packaging device, which are sequentially arranged along the conveying direction of the cement bags, characterized in that the waste detection and recovery device comprises a feed conveying roller, and the cement bags in the waste detection and recovery device are conveyed to the steering device via the feed conveying roller after passing the inspection, the steering device comprises a rotating conveying roller group, and the steering device can stack the cement bags and convey them to the whole bag device via the rotating conveying roller group, the whole bag device comprises a whole bag conveying roller, and the cement bags stacked in the whole bag device are conveyed to the packaging film packaging device via the whole bag conveying roller after being whole bagged, The packaging film packaging device includes a film frame and a flip frame arranged along the conveying direction. The film frame is vertically slidably connected to a plurality of manipulators that can open the bag mouth of the packaging film. The flip frame includes two support plates arranged opposite to each other in the longitudinal direction and a flip bracket rotatably connected between the two support plates. The flip bracket includes an upper conveyor belt and a lower conveyor belt arranged opposite to each other in the vertical direction and capable of sliding up and down. The upper conveyor belt and the lower conveyor belt clamp the cement bag bagged in the film frame, flip it over and send it back to the film frame. The cement bag bagged in the flip bracket can be transported to the packaging device through the upper conveyor belt or the lower conveyor belt. The packaging device is provided with a plurality of balers for bundling the cement bags.

[0008] A single cement bag is conveyed to the waste detection and recycling device, and is inspected by the waste detection and recycling device. The qualified cement bag is conveyed to the steering device by the feed conveyor roller, and the unqualified cement bag is directly removed. The cement bag is stacked in the steering device, and the stacked cement bag is conveyed to the whole bag device by the rotating conveyor roller of the steering device. After the stacked cement bag is packaged by the whole bag device, it is conveyed to the packing film packaging device by the whole bag conveyor roller. The stacked cement bag is heavy, and the entire outer wall of the stacked cement bag needs to be packaged. The packaging film is stretched by the robot on the film rack and moved downward along the film rack so that the packaging film can be put on the stacked cement bag, and then the cement bag with the packaging film on the top surface is moved to the lower conveyor of the turning rack. On the conveyor belt, the upper conveyor belt and the lower conveyor belt are brought close to each other and the cement bag is clamped. After clamping, the flip bracket is flipped 180 degrees along the support plate to turn over the stacked cement bag, and then the upper conveyor belt and the lower conveyor belt are separated. After separation, the stacked cement bag is transported by the upper conveyor belt and moved to the film rack. Then another packaging film is stretched out by the robot and moved downward along the film rack, and the other packaging film is put on the bottom surface of the stacked cement bag, so that the entire outer circumference of the stacked cement bag is bagged with the packaging film, so that the cement bag with the strapping can be transported to the packaging device, and the strapping belt in the packaging device is used to bundle the cement bag. After bundling is completed, the bundled cement bag can be clamped and transferred to the truck by the existing robot.

[0009] The above structure realizes the removal of waste materials from cement bags, stacking, whole bagging and packaging, etc. through the cooperation of waste detection and recovery device, steering device, whole bagging device, packaging film packaging device and packaging device. The whole packaging production line adopts fully automatic production, does not require manual operation, realizes unmanned packaging and transportation, and improves the packaging and transportation quality of cement bags. In addition, by adopting packaging film packaging device on stacked cement bags, the packaging of the entire outer surface of the stacked cement bags is achieved, ensuring that the stacked cement bags can be stably packaged by packaging film first and then tied by strapping during the packaging process, avoiding the situation that the packaging film falls off or the situation that the strapping is unstable. Therefore, the method of first applying film and then strapping is adopted to achieve fast and stable packaging and transportation of cement bags, avoiding the situation that the cement bags become loose and fall during transportation, and improving the packaging and transportation efficiency and transportation stability.

[0010] The turning bracket is also provided with a plurality of clamping cylinders which can push the upper conveyor belt and the lower conveyor belt to move closer to or away from each other.

[0011] In the above-mentioned fully automatic packaging production line for cement bags, a transverse film conveying roller is provided in the film frame, a flip motor is connected to the support plate, and the flip bracket includes two flip frames arranged opposite to each other in the longitudinal direction, a flip plate is fixed in the middle of the flip frame, the middle of the flip plate is fixedly connected to the motor shaft of the flip motor, and the outer wall of the flip plate is in contact with the side wall of the support plate.

[0012] By providing a flip frame, the overall weight of the flip bracket is greatly reduced. The middle part of the flip frame is fixedly connected to the motor shaft of the flip motor, so that the center of the flip frame can be acted upon during flipping, thereby improving the stability of the flipping.

[0013] In the above-mentioned fully automatic packaging production line for cement bags, the flip frame is provided with two slide rails arranged opposite to each other along the conveying direction, and the left and right sides of the upper conveyor belt and the lower conveyor belt are connected with sliding bars, which are arranged between the two slide rails of the corresponding flip frame, and both ends of the sliding bar are connected with sliders slidably connected to the slide rails.

[0014] By setting the slide rails, the sliding of the upper conveyor belt and the lower conveyor belt is made more stable, and by setting the sliding bar, not only the vertical limit can be achieved, but also the positioning in the conveying direction can be achieved through the sliding connection between the two ends of the sliding bar and the slide rails. Therefore, the cooperation between the sliding bar and the slide rail realizes the limit guidance in two directions, thereby ensuring the sliding stability of the upper conveyor belt and the lower conveyor belt.

[0015] In the above-mentioned fully automatic packaging production line for cement bags, an upper crossbeam arranged along the front-to-back direction is connected above the upper conveyor belt, and the front and rear ends of the upper crossbeam are connected to upper limit bars arranged along the left-right direction and abutted against the flip frame, and the outer side of the upper limit bar is connected to a corresponding sliding bar, and a lower crossbeam arranged along the front-to-back direction is connected above the lower conveyor belt, and the front and rear ends of the lower crossbeam are connected to lower limit bars arranged along the left-right direction and abutted against the flip frame, and the outer side of the lower limit bar is connected to a corresponding sliding bar.

[0016] By setting the sliding bar on the outside of the upper limit bar and the outer wall of the upper limit bar in contact with the flip frame, the upper limit bar and the sliding bar form a "convex" shaped structure, which can not only slide stably along the slide rail, but also stably realize the positioning of the movement of the upper conveyor belt, thereby ensuring the accuracy of sliding. The sliding bar is set on the outside of the upper limit bar and the outer wall of the lower limit bar in contact with the flip frame, so that the lower limit bar and the sliding bar form a "convex" shaped structure, which can not only slide stably along the slide rail, but also stably realize the positioning of the movement of the lower conveyor belt, thereby ensuring the accuracy of sliding, so that the cement bag can be subjected to uniform upper and lower clamping forces when clamped, and the flipping effect is better.

[0017] In the above-mentioned fully automatic packaging production line for cement bags, the waste detection and recovery device also includes a transversely arranged feed roller group 1 and a support frame provided with a drive motor, and the support frame is rotatably connected to a feed roller group 2 which is arranged transversely and driven by a drive motor, and the feed conveying roller is connected to the feed roller group 2, and a feed roller group 3 is provided below the feed roller group 2, and a weighing platform for weighing the cement bag and moving it backward is provided between the feed roller group 1 and the feed roller group 2, and the input end of the feed roller group 2 can swing up and down relative to the output end of the weighing platform under the drive of the drive motor, and a controller is provided on the weighing platform which is connected to the drive motor and is used to control the start and stop of the drive motor.

[0018] The cement bag is moved to the feeding roller group 1 and transported backward by it, so that the cement bag flows to the weighing platform. At this time, the weighing platform weighs the cement bag while synchronously transporting the goods backward. The data obtained by weighing is used as the command basis of the controller. When the weight of the cement bag meets the requirement, the controller does not send any instructions to the drive device. At this time, the cement bag is transported to the feeding conveyor roller to the next workstation. When the weight of the weighed cement bag does not meet the standard, the controller can control the drive device to operate, and the driving motor drives the feeding roller group 2 on the support frame to rotate, so that the feeding roller group 2 The input end tilts upward, and the conveying path between the second feed roller group and the weighing platform is disconnected. The cement bag transmitted backward through the weighing platform falls to the third feed roller group below the second feed roller group due to gravity, and is transported back to the loading area for rework by the third feed roller group. Through the setting of this structure, relying on the cooperation of multiple feed roller groups and weighing platforms, the purpose of intelligent classification is achieved. There is no need to transport cement bags time-consuming and laborious. Under the premise of ensuring labor saving, the underweight cement bags can be screened, recycled and refilled. While removing unqualified cement bags, it also ensures fully automatic transportation of cement bags.

[0019] In the above-mentioned fully automatic packaging production line for cement bags, an adjusting shaft is fixed to the output end of the feed roller group 2, the drive motor is fixed on the support frame, the output end of the feed roller group 2 is connected to the drive motor through the adjusting shaft, and the input end is arranged close to the weighing platform.

[0020] On the premise of ensuring the installation stability of the feed roller group 2, the feed roller group 2 can use the adjusting shaft as the fulcrum, and control the input end of the feed roller group 2 to swing up and down through the transmission force between the driving device and the adjusting shaft, so as to achieve the purpose of classifying and transporting cement bags. As a further explanation, the adjusting device disclosed in this application can be the existing technology, specifically a motor and a reducer, and the transmission between the reducer and the adjusting shaft is realized through gears and chains.

[0021] In the above-mentioned fully automatic packaging production line for cement bags, the waste detection and recovery device includes a mounting frame, the feed conveyor roller is arranged on the mounting frame, the mounting frame is provided with a double door panel, the discharge end of the feed conveyor roller is provided with the above-mentioned steering device, the steering device includes a plurality of conveying platforms arranged for longitudinal sliding and which can be located under the double door panel, the conveying platform includes a push plate and a storage platform for cement bags to be stacked, the discharge end of the conveying platform is provided with a plurality of the above-mentioned rotating conveying roller groups that can rotate circumferentially, the cement bags on the storage platform are pushed to the corresponding rotating conveying roller groups by the push plate, and the discharge end of one of the rotating conveying roller groups is connected to the feed end of the film conveying roller.

[0022] The cement bags that have passed the waste material inspection are transported through the feed conveyor rollers to the double-door panels of the mounting frame. The double-door panels can be opened, and the cement bags fall down under their own gravity and fall onto the storage platform. After multiple cement bags fall, stacked cement bags are formed. The cement bags on the storage platform are then pushed to the corresponding rotating conveyor roller group by the push plate on the conveying platform. The cement bag is conveyed to the sleeve conveyor roller by one of the rotating conveyor roller groups. The double-door structure and the arrangement of multiple conveying platforms enable the cement bags to be quickly stacked and turned for transportation, so that the cement bags can be stacked while another group of cement bags can be transported synchronously, thereby improving the stacking and transportation efficiency of the cement bags.

[0023] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0024] The shaping bracket 1 is moved upward, and the stacked cement bags are transported to the whole bag rack through the whole bag conveying roller, and then the shaping bracket 1 is moved downward, so that the shaping plate 1 of the shaping bracket 1 is located on the left and right sides of the stacked cement bags, and the shaping plate 2 is also located on the front and back sides of the stacked cement bags, and the corresponding driving member 1 and driving member 2 are driven, so that the shaping plate 1 and the shaping plate 2 can move relative to each other in the front and back directions and the left and right directions and press and shape the stacked cement bags on all sides, thereby realizing the shaping of the four sides of the stacked cement bags, and no shaping structure is set on the upper part of the stacked cement bags, so During shaping, the gas in the cement bag can be easily discharged from the top, avoiding the problem that the stacked cement bags are easily squeezed and deformed due to insufficient space, and by fixing the whole bag slide rail on the vertical rod of the base frame, the shaping bracket 1 and the shaping bracket 2 are fixedly connected with the whole bag slider. When the shaping bracket 1 and the shaping bracket 2 slide vertically, the whole bag slider guides along the whole bag slide rail, thereby ensuring the shaping effect of the shaping bracket 1 and the shaping bracket 2 during the up and down movement, avoiding displacement deviation of the shaping plate 1 and the shaping plate 2 as they move up and down, and improving the shaping effect of the stacked cement bags.

[0025] The first driving member and the second driving member are both motors.

[0026] In the above-mentioned fully automatic packaging production line for cement bags, the packaging device includes a packaging roller group arranged along the conveying direction, and two groups of the above-mentioned packaging machines are provided on the packaging roller group, and the two groups of the packaging machines are arranged at intervals along the length direction of the packaging roller group. The packaging roller group is also provided with a rotating table, and the rotating table is located between the two groups of the packaging machines.

[0027] The present application utilizes a packing roller group as a transmission tool to transport the stacked cement bales in an orderly manner from front to back. On this basis, the present application arranges two groups of balers on the packing roller group, and arranges a rotating table between the two groups of balers on the conveyor line. During the packing process, the cement bales transferred from the packing roller group first pass through one of the groups of balers, and the balers are used to pack the cement bales once. Then, the cement bales are transported to the rotating table, and the rotation of the rotating table is used to realize the rotation reversal of the cement bales. After that, the cement bales continue to be transported backward so that the cement bales reach the position of another group of balers and pass through the second group of balers. The cement stacking group is packaged for the second time. It is worth mentioning that the packaging operation is to use binding ties to bundle two of the side surfaces, top and bottom surfaces of the cement stacking group. The setting of the turntable allows the cement stacking group to rotate ninety degrees under its drive. When it passes through the transmission and comes to the second set of packaging machines, its other two side surfaces, top and bottom surfaces are bundled for secondary packaging. The two binding ties tied to the cement stacking group are arranged in a cross shape. Through this setting, the binding firmness of the cement stacking group can be improved while reducing labor costs to the greatest extent, thereby ensuring stability during subsequent handling and transportation and avoiding leakage.

[0028] In the above-mentioned fully automatic packaging production line for cement bags, the fully automatic packaging production line also includes a transporting device, which includes a truss and a transporting roller group arranged along the transverse direction. The input end of the transporting roller group is connected to the input end of the packaging roller group. The transporting roller group is located inside the truss. The truss is provided with a mechanical arm that can slide longitudinally and transversely. There are several mechanical arms, and the several mechanical arms are arranged at intervals along the length direction of the transporting roller group, and each of the mechanical arms is arranged vertically and can be extended and retracted vertically.

[0029] The present application transfers the cement bag group through the roller conveyor line. Through the setting of the truss, several groups of mechanical arms that can slide horizontally and vertically can be set above the roller conveyor line, and several mechanical arms are arranged at intervals along the length direction of the roller conveyor line. When working, the driver parks the truck on one side of the roller conveyor line and is located inside the truss. At this time, the mechanical arm can move back and forth between the truck compartment and the roller conveyor line, and the cement bag group on the roller conveyor line is grabbed by the grabbing action of the mechanical arm, and the cement bag group is transferred to the compartment under its translation action. For row stacking, when the stacking reaches a certain height in this area, the lateral translation of the robotic arm (i.e. translation along the length direction of the roller conveyor line) is utilized, so that the robotic arm is located in the area with lower stacking height and continues to work in the above manner. On this basis, through the cooperation of several groups of robotic arms and roller conveyor lines, it is possible to increase the conveying speed of the roller conveyor line while having several groups of robotic arms cooperate to quickly pick up and stack the cement bags. No manual intervention is required during the entire process. Compared with the existing technology, it can effectively reduce labor costs, while also ensuring the loading and handling efficiency of the cement bags.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. The above structure realizes the removal of waste materials from cement bags, stacking, whole bagging and packaging, etc. through the cooperation of the waste detection and recovery device, the steering device, the whole bagging device, the packaging film packaging device and the packaging device. The entire packaging production line adopts full-automatic production and does not require manual operation, thereby improving the packaging and transportation quality of the cement bags. In addition, by adopting the packaging film packaging device on the stacked cement bags, the entire outer surface of the stacked cement bags is packaged, ensuring that the stacked cement bags can be stably packaged by the packaging film first and then tied by the strapping tape during the packaging process, avoiding the situation where the packaging film falls off or the strapping is unstable. Therefore, the method of first covering the film and then strapping is adopted to achieve fast and stable packaging and transportation of the cement bags, thereby improving the packaging and transportation efficiency.

[0032] 2. The setting of the slide rail makes the sliding of the upper conveyor belt and the lower conveyor belt more stable, and by setting the sliding bar, not only the vertical limit can be achieved, but also the positioning in the conveying direction can be achieved through the sliding connection between the two ends of the sliding bar and the slide rail. Therefore, the cooperation of the sliding bar and the slide rail realizes the limit guidance in two directions, ensuring the sliding stability of the upper conveyor belt and the lower conveyor belt.

[0033] 3. The waste detection and recovery device relies on the cooperation of multiple feeding roller groups and weighing platforms to achieve the purpose of intelligent classification. There is no need to carry cement bags in a time-consuming and laborious manner. Under the premise of ensuring labor saving, it can screen, recycle and refill cement bags that are underweight. While achieving the removal of unqualified cement bags, it also ensures the fully automatic transportation of cement bags. BRIEF DESCRIPTION OF THE DRAWINGS
