Description

Technical Field

[0001] This invention relates to the field of palletizing technology, specifically to a palletizing device and method for conveying and labeling pallets in and out of warehouses. Background Technology

[0002] In the lead smelting process, lead is electrolyzed and smelted to produce lead ingots, which are then stacked and packaged by robotic arms before being removed from the production line. In related technologies, manual transfer involves using forklifts to move lead stacks from the production line to a ground storage area. During shipment, according to the shipping order, manual picking and hoisting of lead stacks are first carried to a ground scale for weighing. After receiving the weight, a labeling machine prints the weight information onto labels, which are then manually affixed to two adjacent sides of the stack. Finally, an overhead crane lifts the stacks to a truck for loading. This weighing, labeling, and hoisting process requires five or six people, and the work is repetitive. Workers must also avoid overhead stacks, and the manual picking and labeling information needs to be manually entered into the shipping system. If anyone interrupts the work, errors are easily made.

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] The following description, with reference to the accompanying drawings, describes a stacking and labeling device for inbound and outbound transport according to an embodiment of the present invention. Figures 1 to 4 As shown, the stacking and labeling device according to an embodiment of the present invention includes a storage area 1, a conveying section, an outbound section, a labeling device 4, and a control unit.

[0023] Storage area 1 is equipped with an inbound / outbound mobile conveyor 11, which is used for storing and removing stacks of goods. Specifically, storage area 1 is an area for storing stacks of goods, and the inbound / outbound mobile conveyor 11 includes an inbound / outbound truss car body clamping assembly 111 and an inbound conveyor 112. The inbound / outbound truss car body clamping assembly 111 includes an inbound / outbound truss, an inbound / outbound car body, and inbound / outbound clamps. The inbound / outbound car body moves along the width and length directions of the inbound / outbound truss. The inbound / outbound clamps are mounted on the inbound / outbound car body and can clamp the stacks of goods, which are then transported by the inbound / outbound car body to storage area 1. The inbound conveyor 112 is used to transport the stacks of goods to the inbound / outbound truss car body clamping assembly 111 at the entrance of storage area 1. The inbound conveyor 112 is a belt conveyor or a roller conveyor.

[0024] like Figure 1 As shown, the conveying unit includes a first conveyor 21, a first mobile conveying device 22, a weighing machine 23, and a second conveyor 24.

[0025] The first conveyor 21 is used to transport the palletized stacks to a direction adjacent to the first mobile conveyor 22. The first mobile conveyor 22 is used to move the stacks on the first conveyor 21 to the weighing machine 23 for weighing, and then move the weighed stacks to the second conveyor 24. This facilitates the weighing of the palletized stacks.

[0026] Specifically, the first mobile conveying device 22 includes a weighing truss car body clamping assembly 221, with the weighing machine 23 located below it. The weighing truss car body clamping assembly 221 includes a weighing truss, a weighing car body, and weighing clamps. The weighing car body and its weighing clamps are movably mounted on the weighing truss. The weighing clamps grip the stacks on the first mobile conveying device 22, move them to the weighing machine 23, and then place the stacks on the weighing machine 23 for weighing. After weighing, the stacks are gripped again, moved, and placed on the second conveyor 24.

[0027] In some embodiments, there are one or more weighing machines 23 to improve weighing accuracy. For example, there are two weighing machines 23.

[0028] The second conveyor 24 is used to transport the stacks to the storage area 1. The stacks on the second conveyor 24 can be moved into the storage area 1 by the inbound / outbound mobile conveyor 11. Specifically, the second conveyor 24 is equipped with a rail-guided vehicle (RGV) whose track is already in place. After the weighing gantry car body clamping assembly 221 places the stacks onto the rail-guided vehicle, the rail-guided vehicle transports the stacks to the inbound conveyor 112.

[0029] like Figure 1 As shown, the outbound section includes a third conveyor 31 and a loading mobile conveyor 32. The outbound mobile conveyor 11 can move the stacks in the storage area 1 onto the third conveyor 31. The third conveyor 31 is used to transport the stacks to the loading area 5. The loading mobile conveyor 32 is used to move the stacks on the third conveyor 31 onto the outbound vehicle body. Specifically, the loading mobile conveyor 32 includes a loading truss vehicle body clamping assembly 321. The loading truss vehicle body clamping assembly 321 includes a loading truss, a loading vehicle body, and loading clamps. The loading vehicle body moves along the width and length directions of the loading truss. The loading clamps are located on the outbound loading vehicle body and can clamp the stacks and transport them from the loading vehicle body to the outbound vehicle body. Thus, the inbound / outbound truss car body clamping assembly 111 can move the stacks with weighing information onto the third conveyor 31, and the loading moving conveyor 32 (loading truss car body clamping assembly 321) can move the stacks on the third conveyor 31 onto the outbound car body in the loading area 5. For example, the third conveyor 31 is a belt conveyor or a roller conveyor.

[0030] In some embodiments, each loading area 5 is provided with two third conveyors 31, and the area between the two third conveyors 31 is used to accommodate the outbound vehicle body. Each third conveyor 31 cooperates with at least one marking device 4. That is, third conveyors 31 are provided on both sides of the outbound vehicle body, and the marking device 4 marks the stacks on each third conveyor 31 in order to improve outbound efficiency.

[0031] In some embodiments, the length direction of the first conveyor 21, the second conveyor 24, the inbound / outbound truss car body clamping assembly 111, the third conveyor 31, and the loading truss car body clamping assembly 321 is a first direction and the stack can be moved in the first direction.

[0032] There are multiple inbound / outbound gantry crane clamping assemblies 111. The length direction of the inbound conveyor 112 and the weighing gantry crane clamping assembly 221 is the second direction. Any two of the first direction, the second direction, and the vertical direction are perpendicular to each other. The inbound conveyor 112 is located at the entrance and exit of the storage area 1. Specifically, the inbound conveyor 112 transports the corresponding stacks to the multiple inbound / outbound gantry crane clamping assemblies 111 at the entrance of the storage area 1, so that the stacks can be stored by the multiple inbound / outbound gantry crane clamping assemblies 111, thereby improving storage efficiency.

[0033] like Figures 1 to 4 As shown, the marking device 4 is used to affix labels to stacks located on the second conveyor 24 or the third conveyor 31, with the labels including the weight information of the stacks. Specifically, the marking device 4 is used to affix labels to stacks located on the third conveyor 31, with the labels including the weight information and shipping information of the stacks. That is, each third conveyor 31 has a matching marking device 4 on its side, thereby facilitating the labeling of stacks located on the third conveyor 31.

[0034] The control unit includes a controller electrically connected to the weighing machine 23 and the marking device 4. The controller receives weight information from the weighing machine 23 and controls the label information output by the marking device 4. Specifically, the control unit receives weighing information from the weighing machine 23, the location information of the stacks within storage area 1, and the weighing information of the stacks within storage area 1. During the stack outbound process, the controller controls the marking device 4 to affix information and shipping information to the outbound stacks.

[0035] In some embodiments, the marking device 4 includes a gantry frame 41, a camera 42, a labeling machine 43, a labeling robot 44, and a host computer 45. Specifically, the marking device 4 is surrounded by a fence, thereby improving production safety.

[0036] A gantry frame 41 is positioned at the labeling location of the third conveyor 31. A camera 42 is mounted on the gantry frame 41 and is used to photograph the stack at the labeling location on the third conveyor 31 to identify the stack's stopping position, stopping angle, and strap position. Specifically, the gantry frame 41 is a portal frame, with its two legs located on either side of the width of the corresponding third conveyor 31. The camera 42 is positioned above the third conveyor 31, with its lens facing downwards to photograph and identify the stack at the labeling location. When the lead stack moves to the labeling location, the identification camera 42 identifies the stack's stopping position, stopping angle, and strap position from top to bottom, calculates the spatial coordinates of the two adjacent labeling surfaces of the lead stack near the labeling robot 44, and sends these coordinates to the labeling robot 44.

[0037] Labeling machine 43 is used to output labels containing weight and shipping information of the stack. Specifically, labeling machine 43 is used to output labels corresponding to the stack. Labeling machine 43 is installed within the working range of labeling robot 44, and obtains information such as the current weight value of the lead stack, production information, batch number, and loading slip number through warehouse management software, and prints them onto labels, printing two labels at a time.

[0038] The labeling robot 44 is used to affix labels to the stacks at the labeling positions on the third conveyor 31. Specifically, the labeling robot 44 is a six-axis robot, capable of labeling at any angle and position within its working range. The labeling robot 44 is mounted on the side of the third conveyor 31, and its main function is to pick up one label at a time from the labeling machine 3 and affix it to the labeling position given by image recognition; each stack is labeled twice, on two adjacent faces of the stack closest to the robot arm.

[0039] The host computer 45 is used to run image recognition programs, marking programs, and send the running trajectory coordinates and stop commands of the labeling robot. Specifically, the host computer 45 is at least part of the control unit and constitutes at least part of the controller. The host computer 45 is electrically connected to at least one of the labeling machine 43, the labeling robot 44, and the camera 42. The host computer 45 is used to run image recognition programs, marking programs, and send the running trajectory coordinates and stop commands of the labeling robot 44. The host computer 45 includes acquiring weighing information, batch number, date, and other information from the warehouse management software and sending it to the labeling machine to generate label information; it includes scheduling the operation of the labeling robot 44 by the warehouse management software; and it includes image recognition of the stop position, stop angle, and labeling position information of the lead stack to form three-dimensional coordinate values ​​in the labeling space.

[0040] The labeling device 4 is installed on the side of the third conveyor 31. During the outbound transport of the stack (lead stack), when the lead stack moves into the working range of the labeling robot 44 and stops, the positioning camera 42 installed on the top of the gantry 41 above the conveyor line scans and positions the stop position, stop angle, and strap position of the stack (lead stack) to confirm the labeling position. After the robot arm takes the label from the labeling machine and affixes it to the lead stack, the lead stack continues to be transported forward out of the warehouse.

[0041] For example, the arrival detection of the lead stack conveyed by the third conveyor 31 is detected by a large photoelectric switch. The start, stop and acceleration / deceleration of the third conveyor 31 are all controlled by PLC and frequency converter. The labeling robot 44 runs along the motion trajectory according to the instructions and is controlled by servo. The image recognition algorithm is run by the host computer 45.

[0042] In some embodiments, the stack is a lead stack. A labeling robot 44 (labeling device 4) affixes labels to the sides of adjacent sides of the stack in the circumferential direction, positioning the labels on the outer circumferential surface of the lead blocks. This ensures a secure connection between the labels and the lead stack.

[0043] According to an embodiment of the present invention, the labeling device for palletizing and transporting lead stacks weighs each lead stack before it comes off the production line and records the weight in the lead stack transfer software system. This way, all lead stacks in the storage area have known weights, allowing for advance allocation based on the weight of the delivery note and matching each loading order with its corresponding lead stack. The palletizing device 11 transports the lead stacks in storage area 1 to the third conveyor 31 for transport to the loading area. A labeling device 4 is installed next to the third conveyor 31, and a labeling robot 44 picks up two identical labels with the weight information of the lead stack from the labeling machine 43 and affixes them to two adjacent sides of the lead stack. The position of the lead stack is located and detected using image recognition. A gantry 41 is set up at the labeling position, and a camera 42 is installed on top of the gantry 41, pointing downwards to detect the lead stack stopped at the labeling position. After labeling, the lead stack continues to be transported to the loading area 5, where it is then loaded onto the truck by the loading mobile conveyor 32.

[0044] According to embodiments of the present invention, the palletizing and labeling device for inbound and outbound transport of lead pallets automatically acquires label information, automatically identifies and automatically labels the pallets during the outbound shipment and loading process. This improves the level of automation, eliminates the need for manual intervention, and saves labor costs. Furthermore, it is more accurate and faster, saving both manpower and material resources.

[0045] Image recognition determines the location and labeling point of the lead stack, and a robotic arm replaces manual labeling. At the same time, the weight information and shipping information of the lead stack are automatically recorded into the shipping system, and the label information is uniformly scheduled, managed and recorded by the host computer to achieve traceability.

[0046] The present invention also proposes a stacking and labeling method for stacking and labeling in / out of warehouses using a stacking and labeling device according to an embodiment of the present invention. The stacking and labeling method for stacking and labeling in / out of warehouses according to an embodiment of the present invention includes the following steps: The palletized stacks are weighed using a conveyor system, and the control unit stores the weighed value of the stacks in the warehouse management system. The palletized stacks with weighing information are moved to storage area 1 using the conveyor system and the inbound / outbound moving conveyor 11, and the storage location is recorded. Thus, after weighing, the palletized stacks are transported to storage area 1, and the storage location of the stack is associated with the weighing information, so that the weighing information of the stack at the corresponding location can be recorded.

[0047] When outbound shipment is required, the inbound / outbound mobile conveyor 11 moves the stack to the third conveyor 31, which then moves it to the marking position. The marking device 4 affixes a corresponding label to the stack at the marking position, with the label including the stack's weight information and shipping information. The loading mobile conveyor 32 moves the tagged stack to the outbound vehicle. Specifically, when shipment is required, stacks of a preset weight need to be moved to the third conveyor 31 based on recorded information. The marking device 4 then affixes labels containing weight and shipping information to the corresponding stacks, facilitating shipment. For example, the shipping information includes at least one of the following: weight information, production information, manufacturer, logo, batch number, and loading slip number.

[0048] For example, when lead stacks are shipped out of the warehouse, the warehouse management software system first receives the delivery order, selects zinc stacks in the storage area according to the number of vehicles, and breaks them down into loading lists for each vehicle according to the order of the delivery order. Each outbound task in the loading list involves hoisting the lead stacks from the warehouse area to the outbound conveyor line, labeling them through the labeling machine 43, and then sending them to the loading area 5 for loading. This scheduling task is sent to the warehouse management software system's scheduling software. When the system executes each outbound task, the inbound / outbound mobile conveyor 11 places the lead stacks onto the third conveyor 31 and transports them forward in sequence. When the lead stack reaches the labeling position, the weight, production information, manufacturer, logo, and other information of the current lead stack are obtained through warehouse management software and printed by the labeling machine 43. The positioning and recognition camera 42 installed above the labeling position identifies the current stop position, stop angle, and labeling position of the lead stack, forming labeling space coordinates, which are sent to the labeling robot 44. The labeling robot 44 picks up the label from the labeling machine 43 and affixes it to the labeling position of the lead stack, affixing one label to each of the two adjacent sides. After labeling is completed, the lead stack continues to be transported forward to the loading area for loading.
