Description

TECHNICAL FIELD

[0001] The utility model relates to automatic stacking device, concretely relates to a carton multi-box fast stacking system. BACKGROUND

[0002] In today's logistics and warehousing industry, as a widely used packaging container, the efficiency and quality of the carton stacking operation have a crucial influence on the operation cost of enterprises and the smoothness of production process.

[0003] The traditional carton stacking system exposes many drawbacks in practical application. In terms of stacking efficiency, the early stacking system mostly relies on manual operation, and workers need to carry and stack cartons one by one. This way not only has great labor intensity, but also due to the limitation of human strength and operation speed, the stacking speed is extremely slow. With the continuous expansion of enterprise production scale and the continuous growth of order quantity, the low efficiency of manual stacking seriously restricts the turnover speed of goods, and cannot meet the market demand of fast delivery. Even if some enterprises introduce some automatic equipment, such as simple conveyor belt matched with single suction cup suction device, only one carton can be sucked and stacked each time, the frequency of round trip is frequent, and the overall stacking efficiency is limited.

[0004] In the turning link of carton, the traditional turning device has complex structure and large control difficulty. Some systems adopt complex mechanical turntable or turning mechanism driven by multiple motors, which not only has high equipment cost, but also is prone to failure during operation and needs frequent maintenance. More importantly, these turning devices often need to pause the conveying line when turning the carton, which undoubtedly further reduces the overall conveying efficiency. For example, when the horizontally conveyed carton needs to be turned to be vertically stacked, due to the unsmooth turning process, the conveying line often stops for a long time, affecting the continuity of the whole production process.

[0005] In addition, the traditional suction device has single function and cannot meet the diversified stacking demand. The single suction cup suction device can only suck one carton each time, and needs to spend a lot of time on round trip when facing the stacking task of a large number of cartons. Moreover, when encountering cartons of different specifications and sizes, the traditional suction device lacks enough flexibility and cannot quickly adapt and efficiently suck, so that the efficiency and accuracy of stacking operation are greatly discounted.

[0020] The paper box multi-box rapid stacking system has unique advantages in design, and through the cooperation between various devices and the application of an optimized technical solution, it exhibits many beneficial effects.

[0021] (I) Significantly improve the stacking efficiency

[0022] ① High-efficiency automatic collaborative operation: the conveying device, the turning device, the positioning device, the suction device, and the bearing device are connected to the PLC control system through control elements, realizing automatic control of the whole process. The PLC control system can accurately coordinate the actions of each device, making the paper boxes closely connected in the conveying, turning, positioning, suction, and stacking links, greatly reducing manual intervention and operation time. Compared with traditional manual stacking or simple automatic stacking methods, the efficiency can be improved by several times or even dozens of times, meeting the needs of large-scale production and rapid delivery. ② Rapid continuous conveying: the roller conveying line can continuously convey paper boxes, avoiding pauses in the conveying process and ensuring the rapid flow of paper boxes. The inclined roller line and the movable blocking device in the turning device cooperate to change the direction of the paper boxes without stopping the conveying, ensuring the continuity of the conveying and further improving the overall conveying efficiency. ③ Multiple box suction at the same time: the dense suction cups in the suction device can simultaneously suction multiple paper boxes arranged horizontally or vertically. Compared with traditional single-suction cup suction devices, the frequency of the collaborative robot's round trips is greatly reduced. For example, when handling a large number of paper boxes, the traditional single-suction cup device may need to make dozens or even hundreds of round trips, while the dense suction cups of the system can suction multiple paper boxes at a time, greatly reducing the number of round trips and significantly shortening the stacking time and improving the stacking efficiency.

[0023] (II) Precise positioning and reliable grabbing

[0024] ① Precise positioning mechanism: the positioning device realizes precise positioning of the paper boxes through the suction position set at the end of the roller conveying line and the related auxiliary structure. The extension baffle at the end of the suction position and the guide plates on both sides cooperate to accurately limit the position of the paper boxes, ensuring that the paper boxes are in the best state when suctioned. The guide part of the guide plate at the inlet position bends outward, guiding the paper boxes to smoothly enter the suction position, further improving the accuracy and stability of the positioning. ② Reliable suction and handling: the dense suction cups are connected to the collaborative robot through the connecting flange, with a stable structure. The multiple suction cups distributed along the length of the suction beam at the bottom of the suction frame can be flexibly adjusted according to the size and arrangement of the paper boxes, ensuring reliable suction of the paper boxes. The collaborative robot can accurately drive the dense suction cups to run above the positioned paper boxes, accurately suction and handle the paper boxes to the tray of the bearing device, ensuring the accuracy and reliability of the stacking operation.

[0025] (III) Flexible adaptation to diversified needs

[0026] ①Flexible paper box turning: The unique design of the movable blocking device enables flexible turning of the paper boxes. The movable blocking device has two state settings, i.e., parallel to the running direction of the paper boxes without blocking the longitudinal conveying of the paper boxes, and perpendicular to the running direction of the paper boxes to block the corners of the paper boxes to change to horizontal conveying under the action of the inclined roller line, which can meet the diversified needs of different stacking layouts for the direction of the paper boxes. Whether the paper boxes need to be stacked horizontally or longitudinally, it can be easily realized, improving the applicability of the stacking system. ②Adapt to different paper box specifications: The setting of multiple suction cups on the suction beam of the intensive suction cup enables flexible adjustment according to paper boxes of different specifications and sizes. For larger size paper boxes, multiple suction cups can be used to ensure the stability of suction; for smaller size paper boxes, precise suction can also be achieved by reasonably combining the suction cups. This flexibility enables the stacking system to adapt to paper boxes of various specifications, expanding its application range.

[0027] (Four) Structure optimization and cost reduction

[0028] ①Simplify the structure of the turning device: The turning device adopts the combination of inclined roller line and movable blocking device, which is simple in structure and easy to control. Compared with the traditional complex mechanical turntable or multiple motor driven turning mechanism, not only the equipment cost is reduced, but also the failure rate during operation is reduced, and the maintenance cost is reduced. At the same time, since it does not need to pause the conveying line during conveying to complete the turning operation, the use efficiency of the equipment is improved, which indirectly reduces the overall operating cost. ②Improve the overall reliability of the system: The devices work in coordination through the PLC control system, making the operation of the entire stacking system more stable and reliable. The system can monitor the running state of each device in real time, find and solve potential problems in time, reduce the downtime caused by equipment failure, and improve the production efficiency. In addition, the optimized design of the system also reduces the dependence on manual work, reduces the labor cost, and further improves the economic benefits of enterprises.

[0040] In the description of the present application, it should also be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "installation", "connection", "connection" should be broadly understood, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above-mentioned terms in the present application can be understood according to the specific circumstances.

[0041] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0042] Example 1:

[0043] As Figures 1-7As shown, a carton multi-box rapid stacking system includes a conveying device, a turning device, a positioning device, a suction device, and a bearing device. The conveying device includes a roller conveying line 2 for continuously conveying cartons 1, which can continuously and stably convey the cartons 1 to ensure the efficiency of carton circulation. At the same time, sensors, such as photoelectric sensors, installed beside the conveying line can monitor the conveying state of the cartons in real time. Once an abnormality such as carton jamming or deviation from the conveying line occurs, the sensor immediately feeds back a signal to the PLC control system 8, and the system quickly responds to suspend the operation of the conveying line and issue an alarm, effectively preventing the expansion of the fault and ensuring the smoothness of the conveying process. The turning device includes an inclined roller line 3 and a movable blocking device 4, wherein the inclined roller line and the movable blocking device cooperate to change the direction of the conveyed cartons. The positioning device is used to position the cartons conveyed by the turning device and includes a grabbing position 5 installed at the end of the roller conveying line. The suction device includes a dense suction cup 6 and a collaborative robot 7, wherein the free end of the collaborative robot 8 drives the dense suction cup 6 to run above the positioned cartons, and the horizontally or vertically arranged cartons are placed on the bearing device. The bearing device includes a tray 9.

[0044] The conveying device, the turning device, the positioning device, the suction device, and the bearing device are connected to the PLC control system 8 through control elements. The PLC control system 8 can accurately control the action sequence and time node of each device to realize seamless connection from conveying, turning, and positioning to suction and stacking, greatly reducing manual intervention and significantly improving stacking efficiency. Compared with traditional manual stacking or simple automatic stacking systems, the system can achieve several times or even dozens of times of efficiency growth, effectively meeting the needs of large-scale production and rapid delivery.

[0045] The dense suction cup 6 is connected to the collaborative robot through a connecting flange 602. The dense suction cup includes a suction frame 601, a suction beam 603 installed on the suction frame, and multiple suction cups 604 installed on the bottom of the suction beam along the length direction. The dense suction cup in the suction device can simultaneously suck multiple cartons arranged horizontally or vertically. Compared with the traditional single suction cup that can only suck one carton at a time, the frequency of the collaborative robot's round trip is greatly reduced. For example, when handling a large number of carton stacking tasks, the traditional method may need multiple round trips, while the dense suction cup of the system can suck multiple cartons at a time, greatly shortening the stacking time and improving the overall stacking efficiency.

[0046] The telescopic baffle 501 is arranged at the end of the grabbing position, and the guide plates 502 are arranged on the left and right sides of the grabbing position, and the carton is positioned by the telescopic baffle and the guide plates; the guide plate is provided with the outwardly bent guide portion 503 at the feeding position, so that the carton is guided to enter the grabbing position. The movable baffle box is installed on one side of the inclined roller line, the positioning device is installed at the end of the roller conveying line through the grabbing position, and the telescopic baffle and the left and right guide plates are arranged, so that the accurate positioning of the carton is realized. The telescopic baffle can be flexibly adjusted according to the length of the carton, and the rear end position of the carton is accurately limited; the left and right guide plates limit the two sides of the carton, so that the carton is in a stable and accurate position when being sucked. The outwardly bent guide portion at the feeding position of the guide plate can effectively guide the carton to smoothly enter the grabbing position, and further improve the accuracy and stability of positioning.

[0047] The movable baffle box comprises a movable baffle plate 402 which is movably installed and has an adjustable length. The air cylinder 401 is connected with the PLC control through the electromagnetic valve 403. The movable baffle plate has two states, when the direction of the movable baffle plate is parallel to the running direction of the carton, the carton is not blocked, the carton is not turned, and the carton is longitudinally conveyed, and when the direction of the movable baffle plate is perpendicular to the running direction of the carton, one corner of the carton is blocked, the carton is turned by 90 degrees under the action of the inclined roller line, and the carton is changed into transversely conveyed. The turning device is combined with the movable baffle box by using the inclined roller line, and has the advantages of simple structure and easy control. Compared with a traditional complex mechanical turntable or a multi-motor driving turning mechanism, the device can reduce equipment cost, reduce the failure rate of operation, and reduce maintenance cost. Meanwhile, the turning operation can be completed without stopping the conveying line in the conveying process, the use efficiency of the device is improved, and the overall operation cost is indirectly reduced. The innovative design of the movable baffle box makes the turning of the carton flexible and convenient. The two states of the movable baffle plate are accurately controlled by the PLC control system, when the direction of the movable baffle plate is parallel to the running direction of the carton, the carton is longitudinally conveyed, and when the direction of the movable baffle plate is perpendicular to the running direction of the carton, one corner of the carton is blocked, and the carton is turned by 90 degrees by the inclined roller line to change into transversely conveyed. The design can meet the diversified needs of different stacking layouts for the direction of the carton, and can easily realize horizontal or vertical stacking, so that the applicability of the stacking system is greatly improved.

[0048] The carton multi-box rapid stacking system can realize efficient and accurate carton stacking operation through close cooperation between the devices. The specific implementation mode will be described in detail below.

[0049] ①System initialization setting

[0050] Before the system starts, a series of initialization operations need to be performed. First, according to the size of the paper box to be stacked, the dense suction cup is adjusted. Because the bottom of the suction beam on the suction frame is provided with a plurality of suction cups along the length direction, the number and position of the suction cups can be flexibly selected according to the size of the paper box. For example, for larger size paper boxes, more suction cups can be enabled at the same time to ensure the stability of suction; for smaller size paper boxes, part of the suction cups are reasonably combined to realize accurate suction. At the same time, the state of the movable baffle of the movable baffle of the turning device is checked to ensure that it can normally switch between the two working states. In addition, the PLC control system is programmed and set, and the action parameters of each device are input, such as the conveying speed of the roller conveying line, the running track of the collaborative robot, the switching time of the movable baffle, etc., so that the whole stacking process realizes automatic and accurate operation.

[0051] ②Paper box conveying process

[0052] Roller conveying line starts running: turn on the drive motor of the roller conveying line, and the roller starts rotating at a constant speed. Place the paper box at the starting end of the roller conveying line. Under the drive of the motor, the paper box is quickly and stably conveyed on the roller to the direction of the turning device. During the conveying process, the sensor installed beside the roller conveying line can monitor the conveying state of the paper box in real time. For example, use a photoelectric sensor to detect whether the paper box passes through a specific position normally. If there is an abnormal situation such as paper box jamming or deviation from the conveying line, the sensor will immediately feed back the signal to the PLC control system, and the PLC control system will quickly issue an instruction to pause the operation of the roller conveying line and trigger the alarm device to remind the staff to handle it in time.

[0053] Adjustment and control of conveying speed: according to the overall efficiency requirement of the stacking operation, the conveying speed of the roller conveying line can be flexibly adjusted through the PLC control system. For example, when the paper box supply is sufficient and the stacking task is urgent, the conveying speed can be appropriately increased to speed up the circulation of the paper box; if the suction device or other links appears temporary jam, the conveying speed can be reduced to avoid paper box accumulation and ensure the stable operation of the whole system.

[0054] ③Paper box turning operation

[0055] State switching of movable baffle: when the paper box approaches the turning device, the movable baffle starts to work. If the paper box needs to be conveyed longitudinally, the PLC control system controls the movable baffle to keep parallel to the running direction of the paper box, at this time the movable baffle does not block the paper box, and the paper box continues to be conveyed longitudinally on the roller conveying line. If the paper box needs to be turned to be conveyed horizontally, the PLC control system sends an instruction to drive the movable baffle to rotate to a state perpendicular to the running direction of the paper box.

[0056] Carton turning process: When the movable baffle is in a vertical state, it blocks one corner of the carton. At this time, the diagonal roller line starts to work, and the rollers of the diagonal roller line rotate at a specific angle and speed, generating a diagonal force on the carton. Under the combined action of the blocking of the movable baffle and the force of the diagonal roller line, the carton turns 90 degrees around the blocked corner, thereby changing to horizontal conveying and smoothly entering the subsequent positioning link. During the turning process, the speed and angle of the diagonal roller line are precisely designed and adjusted to ensure that the carton can smoothly and accurately complete the turning without causing damage to the carton.

[0057] ④Carton positioning link

[0058] Entering the grabbing position: The turned carton continues to move along the roller conveying line towards the positioning device and finally enters the grabbing position arranged at the end of the roller conveying line. At the feeding position of the grabbing position, the outwardly bent guide part of the guide plate plays a role in guiding the carton to smoothly enter the grabbing position, avoiding the difficulty of positioning due to positional deviation of the carton.

[0059] Precise positioning: When the carton enters the grabbing position, the telescopic baffle at the end of the grabbing position extends and, together with the guide plates on the left and right sides, positions the carton. The telescopic baffle can be adjusted according to the length of the carton to ensure that the rear end of the carton is accurately positioned. The guide plates on the left and right sides limit the two sides of the carton, so that the carton is in a stable and accurate position when being sucked, creating good conditions for efficient suction of the suction device. During the positioning process, the PLC control system can make fine adjustments to the extension length of the telescopic baffle and the spacing of the guide plates according to the positional information of the carton fed back by the sensor, further improving the accuracy of positioning.

[0060] ⑤Carton suction and handling

[0061] Collaborative robot drives dense suction disc movement: After the carton is precisely positioned, the PLC control system issues an instruction to the collaborative robot, which drives the dense suction disc connected to its free end to move above the positioned carton according to the preset path and speed. The motion trajectory of the collaborative robot is precisely planned to ensure that the dense suction disc can accurately and quickly reach the suction position while avoiding collisions with other devices. During the movement, the speed and acceleration of the collaborative robot can be adjusted according to the weight of the carton and the stacking requirements to ensure the smoothness of the handling process.

[0062] Intensive suction cup suction carton: After the intensive suction cup reaches the appropriate position above the carton, the suction cup starts to work. According to the arrangement of the carton (horizontal arrangement or vertical arrangement) and the size, multiple suction cups work together to firmly suck the carton through negative pressure adsorption. During the suction process, the suction force of the suction cup can be monitored in real time through the pressure sensor to ensure that the suction force is sufficient and uniform, preventing the carton from falling during the handling process. For example, for multiple horizontally arranged cartons, multiple suction cups at corresponding positions on the suction beam can be simultaneously activated for suction; for vertically arranged cartons, the suction cups are also reasonably selected for adsorption according to the position and number of the cartons.

[0063] Transport to the carrying device: After the suction cup sucks the carton, the collaborative robot moves the carton from the grabbing position and moves to the top of the tray of the carrying device according to the preset path. After reaching the top of the tray, the collaborative robot controls the suction cup to release the carton, so that the carton is accurately placed on the tray. According to the stacking requirements, multiple layers of cartons can be stacked on the same tray according to a certain arrangement. After stacking is completed, the collaborative robot returns to the initial position and prepares for the next suction and stacking operation.

[0064] ⑥Carrying device and system maintenance

[0065] Tray use and management: The tray of the carrying device is used to place the stacked cartons. The size and structure of the tray are designed according to the specifications of the cartons to ensure that the cartons can be stably placed. During stacking, a forklift or other handling equipment can be used to timely transfer the full tray of cartons to the storage area and replace a new tray to the stacking position, ensuring the continuity of the stacking operation. At the same time, the condition of the tray is regularly checked, such as whether it is damaged or deformed, and timely maintenance or replacement is performed to ensure normal use of the tray.

[0066] System maintenance and maintenance: In order to ensure the long-term stable operation of the system, regular maintenance of each device is required. For example, regularly check the wear of the rollers on the roller conveyor line and replace the severely worn rollers in time; lubricate the diagonal roller line and movable box stopper of the turning device to ensure its flexibility; check the wear of the telescopic baffle and guide plate of the positioning device and adjust its position or replace it; clean and check the intensive suction cup of the suction device to ensure the adsorption performance of the suction cup; maintain the collaborative robot, including checking the lubrication of the joint parts and the running state of the motor. In addition, regular software updates and hardware checks of the PLC control system are also required to ensure its control accuracy and stability. At the same time, a complete equipment operation record and maintenance file is established to facilitate tracking and analysis of the system's operating conditions, timely detection and solution of potential problems, and ensuring that the system is always in the best operating state.

[0067] Finally, it should be noted that the above is only the preferred embodiment of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified to the technical solution recorded in the foregoing embodiments, or equivalent replacement of some technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
