Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, to achieve the above objectives, this application provides a packaging material feeding system, including: an overhead track 1; a loading unit 2, disposed at a corresponding position on the overhead track 1, the loading unit 2 being used to carry packaging materials; a unloading unit 3, disposed at a corresponding position on the overhead track 1, the unloading unit 3 being arranged correspondingly to the feeding end of the packaging equipment; an overhead trolley 4, movably disposed on the overhead track 1, the overhead trolley 4 being equipped with a pick-and-place component 5, the pick-and-place component 5 being used to pick up packaging materials from the loading unit 2 and release packaging materials from the unloading unit 3; and a control unit, signal-connected to the loading unit 2, the unloading unit 3, the overhead trolley 4, and the packaging equipment, the control unit being used to control the overhead trolley 4 to move packaging materials between the target loading unit 2 and the target unloading unit 3 according to the material information of the loading unit 2 and the material demand information of the packaging equipment. Specifically, the overhead track 1 is installed above the packaging operation area and extends along the packaging material loading area, the packaging equipment feeding area, and the trolley maintenance area, the overhead trolley 4 being able to move along the overhead track 1 to transfer packaging materials from the corresponding loading unit 2 to the corresponding unloading unit 3. The loading unit 2 is used to temporarily store packaging materials awaiting supply, and the unloading unit 3 corresponds to the feeding end of the packaging equipment, allowing the packaging materials to enter the packaging equipment or the receiving mechanism at the front end of the packaging equipment after the overhead trolley 4 releases them. The control unit can receive material information such as whether there is material at the loading unit 2, the type of packaging material, and the quantity of packaging materials. It can also receive material demand signals, running signals, pause signals, fault signals, or full material signals from the packaging equipment, and determine the target loading unit 2 for material retrieval and the target unloading unit 3 for material unloading accordingly. This enables the packaging material feeding system to complete material retrieval, conveying, and unloading according to the actual material demand of the packaging equipment, eliminating the need for manual back-and-forth handling between the loading point and the packaging equipment, and eliminating the need for continuous manual judgment of the feeding rhythm. This improves the continuity and automation of packaging material feeding and reduces the probability of waiting due to untimely material supply.

[0022] It should be noted that this application uses a packaging production line that continuously supplies cardboard boxes, partitions, and other packaging materials with equipment such as carton openers and partition feeders as an example for illustration. Of course, it can also be applied to other packaging production lines such as pharmaceutical, food, and daily chemical products.

[0023] In some embodiments of this application, the packaging materials include a first type of packaging material and a second type of packaging material. The feeding unit 2 includes a first feeding position 201 for carrying the first type of packaging material and a second feeding position 202 for carrying the second type of packaging material. The unloading unit 3 includes a first unloading position 301 corresponding to the first feeding position 201 and a second unloading position 302 corresponding to the second feeding position 202. The control unit is used to determine the target unloading position in the unloading unit 3 according to the type of packaging material and the material demand information of the packaging equipment. Specifically, the first type of packaging material and the second type of packaging material are packaging materials with different shapes, sizes, weights, and feeding objects. The first type of packaging material is specifically a carton, and the second type of packaging material is specifically a partition. The first feeding position 201 is used to carry cartons in a stacked or flat state, and the second feeding position 202 is used to carry the partition. In actual production, the feeding unit 2 includes multiple first feeding positions 201 and at least one second feeding position 202, such as setting multiple carton feeding positions and one partition feeding position to meet the needs of simultaneous feeding of multiple packaging materials. After receiving the material demand information from the packaging equipment, the control unit can determine the required packaging material type based on the packaging equipment category corresponding to the material demand information. It then selects the target feeding unit 2 with the corresponding packaging material based on the material information at the feeding unit location. The overhead trolley 4 is then dispatched to the target feeding unit 2 to pick up the material and transport it to the corresponding target unloading unit 3. By distinguishing between the first and second types of packaging materials, it can adapt to automatic feeding scenarios involving multiple packaging materials, avoiding mixed or incorrect feeding of different packaging materials and effectively improving feeding accuracy.

[0024] In some embodiments of this application, the packaging equipment includes a first type of packaging equipment 6 and a second type of packaging equipment 7. A first unloading position 301 is provided with a guide channel 304, which guides the first type of packaging material released by the overhead trolley 4 to the feeding end of the first type of packaging equipment 6. A second unloading position 302 is provided with a receiving platform 303, which receives the second type of packaging material released by the overhead trolley 4 and corresponds to the feeding end of the second type of packaging equipment 7. Specifically, the first type of packaging equipment 6 is a carton opener, and the second type of packaging equipment 7 is a partition feeder. The first unloading position 301 is arranged corresponding to the feeding end of the carton opener, and the guide channel 304 is configured as a chute so that when the overhead trolley 4 releases the carton, the carton can enter the feeding end of the carton opener along the guide channel 304. The second unloading position 302 is arranged corresponding to the feeding end of the partition feeding machine. The receiving platform 303 is a fixed platform, a lifting platform, a roller platform, or a bearing platform with positioning guards. It is used to receive the partitions released by the aerial trolley 4 and to keep the partitions in a suitable posture for entering the partition feeding machine. In a specific production line, multiple first unloading positions 301 can be set up to correspond to multiple carton erecting machines, and multiple second unloading positions 302 can be set up to correspond to multiple partition feeding machines. By setting different unloading structures for different packaging materials, cartons and partitions can enter the corresponding packaging equipment according to their suitable posture, path, and receiving method, effectively reducing post-unloading posture deviations and the need for manual handling, and improving the feeding stability of the packaging equipment.

[0025] In some embodiments of this application, the feeding unit 2 is equipped with a detection component. The detection end of the detection component faces the feeding unit 2 and is used to detect at least one of the following: packaging material presence information, packaging material type information, and packaging material quantity information at the feeding unit 2 location, to form material information, and send the material information to the control unit. Specifically, the detection component is located on the side of the feeding unit 2, with the detection end facing the packaging material placement area. The detection component is one or more combinations of photoelectric sensors, proximity sensors, weighing sensors, vision recognition modules, barcode scanning modules, or radio frequency identification modules. For the carton feeding unit 2, a photoelectric sensor is used to detect whether the carton is in place, and a vision recognition module is used to identify the carton specifications; for the partition feeding unit, a weight sensor or a photoelectric sensor is used to detect the number of partitions or the partition presence status. After the detection component detects that the packaging material is ready, it sends the material information to the control unit, which then combines the material demand information of the packaging equipment to generate a material retrieval task. By setting up the detection component, the control unit can schedule based on the actual material status, avoiding the overhead trolley 4 from going to the empty feeding unit 2 to retrieve materials, reducing empty runs, and lowering the probability of supply interruption due to material shortage.

[0026] In some embodiments of this application, the pick-and-place assembly 5 includes a mounting base 501, a clamping member 502, and an adjustment drive member 503. One side of the mounting base 501 is fixedly connected to the aerial trolley 4, and the other side of the mounting base 501 is fixedly connected to the adjustment drive member 503. The output end of the adjustment drive member 503 is connected to the clamping member 502 and is used to drive the clamping member 502 to move up and down. Specifically, the mounting base 501 is used to connect the pick-and-place assembly 5 to the aerial trolley 4, and the clamping member 502 is disposed at the output end of the adjustment drive member 503. After the aerial trolley 4 reaches the loading unit 2, the adjusting drive 503 drives the clamping component 502 to descend to the packaging material position. After the clamping component 502 clamps the packaging material, the adjusting drive 503 drives the clamping component 502 to rise, causing the packaging material to leave the loading unit 2. After the aerial trolley 4 reaches the unloading unit 3, the adjusting drive 503 drives the clamping component 502 to descend to the release height. The clamping component 502 releases the clamping component or releases the packaging material, allowing the packaging material to fall into the guide channel 304 or the receiving platform 303. The aerial trolley 4 can complete the loading and unloading of packaging materials without relying on manual lifting or receiving from below, which helps to improve the automation level of loading and unloading actions. The clamping component 502 is set as a relatively arranged claw or clamping arm. Optionally, a flexible pad, a limiting surface, or an anti-slip layer is provided on the clamping surface to reduce damage to the carton or partition.

[0027] like Figure 2 As shown, the adjustment drive unit 503 includes a winding drive section, which is connected to the clamping member 502 via a windable steel wire rope 504. After the aerial trolley 4 moves to the loading unit 2, the winding drive section releases the steel wire rope 504, causing the clamping member 502 to lower to the location of the packaging material. After the clamping member 502 clamps the packaging material, the winding drive section winds up the steel wire rope 504 to lift the clamping member 502 and the packaging material. After the aerial trolley 4 moves to the unloading unit 3, the winding drive section releases the steel wire rope 504 again, causing the clamping member 502 to lower to a predetermined unloading height, and then the clamping member 502 releases the packaging material. The clamping member 502 completes the lifting action in a suspended manner, which is suitable for the suspended loading and unloading scenario of the aerial trolley 4, and can reduce the overall space occupied by the adjustment drive unit 503 and improve the stability of the packaging material loading and unloading process. In other embodiments, the adjusting drive 503 can also be an electric cylinder, a pneumatic cylinder, a lead screw lifting mechanism, a gear and rack lifting mechanism, or a synchronous belt lifting mechanism, as long as it can drive the clamping member 502 to rise and fall relative to the overhead trolley 4 to realize the picking and placing of packaging materials.

[0028] In some embodiments of this application, a docking positioning structure is also included. This docking positioning structure includes a positioning post disposed on the clamping member 502 and a guide seat disposed on the unloading unit. The guide seat has a guide opening, and the positioning post extends into the guide opening to maintain a predetermined relative position between the pick-and-place component and the unloading unit 3. Specifically, the positioning post is disposed on the clamping member 502, and the guide seat is disposed at the unloading unit 3. When the aerial trolley 4 moves to the unloading unit 3, the positioning post inserts into the guide opening during the descent of the clamping member 502 to provide guidance. The docking positioning structure maintains a predetermined relative position between the pick-and-place component 5 and the unloading unit 3. Of course, the docking positioning structure also cooperates with the material guide channel 304 or the receiving platform 303 to improve the positional accuracy of the released packaging material before entering the packaging equipment, reduce the release position deviation of the packaging material, and allow the packaging material to enter the case opener or partition dispenser more stably.

[0029] In some embodiments, the aerial track 1 includes a main track 101 and a curved track 102 connected to the main track 101. The loading unit 2 and the unloading unit 3 are arranged at intervals along the extension direction of the aerial track 1. Specifically, the main track 101 is arranged along the main conveying direction of the packaging operation area, and the curved track 102 connects track segments in different directions, enabling the aerial trolley 4 to turn and run between the loading area, unloading area, and maintenance area to adapt to the floor plan layout of different workshops. Furthermore, the loading unit 2 and the unloading unit 3 are arranged at intervals along the aerial track 1, allowing the aerial trolley 4 to sequentially reach the corresponding positions according to the path assigned by the control unit.

[0030] In some embodiments of this application, the packaging material supply system further includes a hoisting assembly, with the overhead track 1 installed above the packaging operation area via the hoisting assembly. Specifically, the hoisting assembly is a hanger, and the overhead track 1 is fixed to the workshop ceiling via the hoisting assembly. The hoisting assembly has a height adjustment function to adjust the installation height of the overhead track 1 according to the height of the packaging equipment, the operating space of the overhead trolley 4, and the height for picking up and placing packaging materials. This allows the overall packaging material supply system to meet the requirements of overhead transport while minimizing the obstruction of ground passageways, and also facilitates the cleaning and maintenance of the packaging operation area.

[0031] In some embodiments of this application, the packaging material feeding system further includes a maintenance station 105, which is located at a corresponding position on the overhead track 1. The control unit is also used to control the overhead trolley 4 to move to the maintenance station 105 when the maintenance conditions are met. Specifically, the maintenance station 105 is located on the lateral branch track 104 of the overhead track 1, and is used for the overhead trolley 4 to stop, inspect, standby, replace the pick-and-place component 5, or troubleshoot. Maintenance conditions include abnormal operation of the overhead trolley 4, positioning deviation, abnormal operation of the pick-and-place component 5, clamping failure, communication abnormality, continuous operation time reaching a preset duration, maintenance cycle reaching, or manual triggering of maintenance commands, etc. When the control unit determines that the overhead trolley 4 meets the maintenance conditions, it stops assigning new feeding tasks to the corresponding overhead trolley 4 and controls it to move along the overhead track 1 to the maintenance station 105. Other overhead trolleys 4 continue to perform feeding tasks, thereby reducing the impact of single trolley maintenance on the continuous operation of the entire packaging production line.

[0032] In another embodiment, the control unit includes a scheduling controller and a programmable logic controller (PLC). The scheduling controller is communicatively connected to the PLC. The control unit controls the aerial cart 4 to perform actions such as picking up, conveying, unloading, waiting, or pausing based on the operating status information of the packaging equipment. Specifically, the scheduling controller generates feeding tasks, selects target loading unit 2 and target unloading unit 3, and plans the travel path of the aerial cart 4. The PLC controls the actions of the detection component, aerial cart 4, picking and placing component 5, unloading unit 3, or the front-end mechanism of the packaging equipment. The scheduling controller communicates with the production management system to receive information such as production batches, packaging material types, packaging equipment status, or data traceability. The control unit communicates wirelessly with the packaging equipment to achieve feeding task generation, path scheduling, equipment linkage, fault suspension, and operation recording, adapting to the needs of pharmaceutical packaging production lines for continuous feeding and data traceability.

[0033] The working process of this application includes a loading stage, a conveying stage, a unloading stage, and a maintenance standby stage. In the loading stage, the front-end conveying equipment places packaging materials such as cartons and partitions into the corresponding loading unit 2. The detection component detects the location, type, or quantity information of the packaging materials and sends the material information to the control unit. When packaging equipment such as the case opener and partition dispenser needs to supply materials, the packaging equipment sends material demand information to the control unit. The control unit determines the target loading unit 2, the target unloading unit 3, and the corresponding overhead trolley 4 based on the material information and material demand information, and issues a material retrieval task to the overhead trolley 4. In the conveying stage, the overhead trolley 4 runs along the overhead track 1 to the target loading unit 2. The pick-and-place component 5 descends and picks up the corresponding packaging material. Subsequently, the overhead trolley 4 runs along the main track 101 and the curved track 102 to the target unloading unit 3. During operation, the overhead trolley 4 is positioned according to the track position, turning area, and the position of the unloading unit 3 to ensure the stability of the packaging materials during the conveying process. During the unloading phase, after the aerial trolley 4 reaches the target unloading unit 3, it positions and coordinates with the unloading unit 3 or the feeding end of the packaging equipment. The pick-and-place component 5 descends and releases the packaging material. If the packaging material is a carton, the carton enters the feeding end of the carton opener through the guide channel. If the packaging material is a partition, the partition first falls to the receiving platform 303 and then enters the partition dispensing machine. After unloading is completed, the aerial trolley 4 sends feedback to the control unit to complete the unloading. The control unit continues to allocate tasks based on new material demand information or controls the aerial trolley 4 to return to the standby position. During the maintenance standby phase, when the aerial trolley 4 malfunctions, the pick-and-place component 5 malfunctions, there is a driving deviation, or the maintenance cycle is reached, the control unit dispatches the aerial trolley 4 to the maintenance station 105 to facilitate staff inspection or replacement of parts.

[0034] In a specific application scenario, the packaging material feeding system is equipped with multiple carton loading positions and at least one partition loading position. Multiple carton unloading positions correspond to multiple carton openers, and multiple partition unloading positions correspond to multiple partition feeders. The overhead track 1 covers the loading area, unloading area, and maintenance area, and connects different workstation areas via curved rails 102. Multiple overhead trolleys 4 are configured, with at least one serving as a backup. When a packaging device issues a material request, the control unit determines the corresponding packaging material type and selects the nearest and operational overhead trolley 4 to perform material retrieval and delivery. When the packaging device slows down, pauses, or malfunctions, the control unit controls the overhead trolley 4 to wait, pause material supply, or transfer the material to other packaging devices requiring supply, ensuring the supply rhythm matches the operating status of the packaging equipment and reducing packaging material accumulation, material shortages, and manual coordination.

[0035] In some embodiments, the overhead track 1, the hoisting assembly, and the unloading unit 3 all adopt an easy-to-clean structure. Specifically, the joints of the overhead track 1 adopt concealed fasteners or a flat transition structure to reduce dust accumulation dead corners. At the same time, for production environments that require clean management, a protective net 103 can also be installed below the overhead track 1 to reduce the risk of parts becoming loose or foreign objects falling.

[0036] In summary, this application utilizes the coordinated structure of overhead track 1, loading unit 2, unloading unit 3, overhead trolley 4, pick-and-place assembly 5, control unit, detection assembly, docking and positioning structure, hoisting assembly, and maintenance station 105 to enable packaging materials to be automatically transported from the corresponding loading unit 2 to the corresponding unloading unit 3 according to the material requirements of the packaging equipment, thus achieving automated material supply. Simultaneously, through multiple types of loading and unloading positions, adjustable pick-and-place assembly 5, and track hoisting layout, the system can adapt to different packaging materials such as cartons and partitions, as well as different packaging equipment such as carton openers and partition feeders, reducing manual handling and manual material feeding, and improving the operational continuity of the packaging production line.

[0037] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0038] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
