Description

Technical Field

[0001] This invention relates to the field of brake shoe packaging technology, and in particular to a method for packaging synthetic brake shoes and an automated packaging production line. Background Technology

[0002] Brake shoes are critical friction components in the braking systems of rail vehicles, construction machinery, and other vehicles. They are typically made of cast iron, composite materials, or sintered materials, have a specific arc-shaped structure, and are relatively brittle. Ensuring the brake shoes remain intact during transportation is crucial; therefore, their packaging process must provide adequate protection.

[0003] Currently, there are two main packaging methods for brake shoes in the industry. The first is cardboard box packaging: operators or machinery pack single or multiple brake shoes into customized cardboard boxes, seal the boxes, and then move the boxes to pallets for stacking, stretch wrapping, and final packaging. The second is individual bare packaging: for applications where cardboard box protection is not required, operators or machinery directly stack individual brake shoes on pallets according to a preset quantity and arrangement, followed by stretch wrapping and final packaging. These two methods are usually completed on different packaging lines, or although they are in the same area, they require frequent switching of equipment and processes.

[0004] However, the existing brake shoe packaging line requires two independent packaging systems in actual use, resulting in repeated investment in equipment, site and labor costs, and low resource utilization. Summary of the Invention

[0005] The purpose of this invention is to provide a method for packaging synthetic brake shoes and an automated packaging production line, which solves the problem that existing brake shoe packaging lines require the maintenance of two independent packaging systems in actual use, resulting in repeated investment in equipment, site and labor costs and low resource utilization.

[0007] The automatic carton opener is provided with a first rotating conveyor between its output end and the packing station of the automatic carton packer; the certificate placement mechanism is provided with a second rotating conveyor between its output end and the input end of the automatic carton sealer; and the first packer is provided with a third rotating conveyor between its output end and the input end of the second packer. The first, second, and third rotating conveyors are all used to rotate the packaging box.

[0008] The first, second, and third rotating conveyor frames each include a roller conveyor frame, a rotary drive mechanism, a lifting mechanism, and a cross-shaped rotating frame. The roller conveyor frame is provided with a rotating section, and the rollers in the rotating section are arranged in a segmented structure. The rotary drive mechanism is installed below the rotating section, and the lifting mechanism is provided at the output end of the rotary drive mechanism. The cross-shaped rotating frame is provided at the output end of the lifting mechanism.

[0009] Each of the rotary drive mechanisms includes a mounting base, a rotating component, and a rotating disk. The mounting base is installed below the rotating section, and the rotating disk is located at the top of the mounting base. The rotating component is located inside the mounting base, and the output end of the rotating component is mechanically driven by the rotating disk.

[0010] The rotating assembly includes a first servo motor and an output gear. A rotating bearing is provided at the top of the mounting base. An embedded ring is provided on the side of the rotating disk facing the mounting base. The embedded ring is embedded inside the rotating bearing. A transmission tooth is provided on the inner side wall of the embedded ring. The first servo motor is installed at the inner bottom of the mounting base. The output gear is provided at the output end of the first servo motor. The output gear meshes with the transmission tooth.

[0011] The lifting mechanism includes a support arm, a sliding arm, and a height adjustment component. The bottom of the support arm is connected to the upper surface of the rotating disk, and the sliding arm is slidably disposed inside the top of the support arm. Both the support arm and the sliding arm are hollow structures. The top of the sliding arm is mounted on the cross rotating frame, and the height adjustment component is disposed at the inner bottom of the support arm. The output end of the height adjustment component is connected to the inner bottom wall of the sliding seat.

[0012] The height adjustment assembly includes a second servo motor, a threaded rod, and a ball screw nut assembly. The second servo motor is installed at the inner bottom of the support arm. The output end of the second servo motor is provided with the threaded rod, and the ball screw nut assembly is provided on the threaded rod. The ball screw nut assembly is connected to the inner bottom wall of the sliding arm.

[0013] The packaging box conveyor line and the palletizing conveyor line are both equipped with safety fences on the side away from the robot palletizer, and the safety fences are located outside the working range of the robot palletizer.

[0014] The present invention also provides a method for packaging synthetic brake shoes, applied to the automated production line for packaging synthetic brake shoes as described above, comprising the following steps: The brake shoes are conveyed forward through the material conveyor line. At the same time, according to the packaging instructions, the boxed palletizing path or the bare component palletizing path of the individual brake shoes is selected. If the boxed palletizing path is selected, the packaging box conveyor line is started simultaneously, and the folded packaging box blanks are unfolded and formed by the automatic box opener and conveyed to the predetermined position; if the bare part palletizing path is selected, the brake shoes are conveyed to the end of the material conveyor line by the material conveyor box. When the unfolded packaging box arrives at the station of the automatic box packer, the automatic box packer grabs the brake shoe units from the material conveyor line in a set quantity and automatically loads them into the unfolded packaging box. The packaging box equipped with brake shoes continues to move along the packaging box conveyor line, passing through the certificate placement mechanism in sequence, where the product certificate is automatically placed into the box. Subsequently, the packaging box enters the automatic box sealing machine, where the tape at the top of the box is sealed. After sealing, the packaging box passes through the first packing machine and the second packing machine in sequence, where it is reinforced horizontally and vertically, respectively. The pallet distributor automatically supplies empty pallets to the palletizing station on the palletizing conveyor line. For the boxed palletizing path, the robot palletizer picks up the packaged whole box brake shoes from the end of the packaging box conveyor line; for the bare part palletizing path, the robot palletizer directly picks up the individual brake shoes from the end of the material conveyor line. The robotic palletizer automatically stacks whole boxes of brake shoes or individual brake shoes on the empty pallet according to the preset stacking pattern. The pallet after stacking is moved along the palletizing conveyor line and enters the automatic top wrapping machine for top film covering and stretch film wrapping around the body. The wrapped pallet continues to move and enters the piercing crisscross packing machine for crisscross piercing and reinforcement. After the packing and reinforcement are completed, the final packaging unit is formed and transported out via the palletizing conveyor.

[0015] This invention discloses a method for packaging synthetic brake shoes and an automated packaging production line, comprising a material conveying line, a carton conveying line, a palletizing conveying line, and a robotic palletizer. It integrates the previously separate carton packaging and individual bare-package functional modules onto a unified production line: brake shoes are supplied via a shared material conveying line, while the parallel carton conveying line is dedicated to carton forming, packing, and sealing. The robotic palletizer, capable of dual-mode operation, can handle both pre-packed brake shoes from the end of the carton conveying line and directly pick up individual brake shoes from the end of the material conveying line, stacking them according to a preset stacking pattern on pallets provided by a pallet distributor. Subsequently, the pallets after stacking are uniformly fed into a shared automatic wrapping machine and a crisscross packing machine for reinforcement. This structure achieves a high degree of sharing of equipment, space, and manpower, allowing a single production line to handle two types of packaging orders, significantly improving resource utilization.

Detailed Implementation

[0024] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0025] Please see Figures 1 to 5This invention provides an automated production line for packaging synthetic brake shoes. The automated production line includes a material conveying line 101, a packaging box conveying line 102, a palletizing conveying line 103, and a robotic palletizer 104. The material conveying line 101 and the packaging box conveying line 102 are arranged side by side. An automatic box packing machine 105 is provided at the front end of the material conveying line 101. An automatic box opening machine 106, a certificate placement mechanism 107, an automatic box sealing machine 108, a first packing machine 109, and a second packing machine 110 are arranged sequentially from front to back on the packaging box conveying line 102. The robotic palletizer 104 is provided at the end of the material conveying line 101 and the packaging box conveying line 102. The palletizing conveying line 103 is provided on the side of the robotic palletizer 104 away from the material conveying line 101. A pallet distributor 111, an automatic wrapping machine 112, and a crisscross packing machine 113 are arranged sequentially from front to back on the palletizing conveying line 103. The automatic packing machine 105 is used to automatically pack the brake shoe units into the unfolded packaging box according to the set quantity; The automatic box unpacking machine 106 is used to automatically unfold and shape the folded packaging box blank; The certificate placement mechanism 107 is used to automatically place the product certificate into a designated position inside the unfolded packaging box. The automatic carton sealing machine 108 is used to seal the top of the packaging box containing brake shoes with tape. The first packing machine 109 is used to horizontally bundle and pack the sealed packaging boxes; The second packing machine 110 is used to longitudinally bundle and pack the packaging boxes; The robotic palletizer 104 is used to stack the packaged boxes or individual brake shoes onto a pallet according to a preset stacking pattern. The pallet distributor 111 is used to automatically supply and position empty pallets to the palletizing station; The automatic wrapping machine 112 is used to cover and wrap the top of the stacked product; The piercing-sword crisscross packing machine 113 is used to reinforce the entire wrapped pallet by piercing-sword crisscrossing.

[0026] In this embodiment, the previously separate cardboard box packaging and individual bare packaging functional modules are integrated into a unified production line: brake shoes are supplied through a shared material conveyor line 101, while the parallel packaging box conveyor line 102 is dedicated to cardboard box forming, packing, and sealing. The robotic palletizer 104, capable of dual-mode operation, can handle both pre-packed brake shoes from the end of the packaging box conveyor line 102 and directly grab individual brake shoes from the end of the material conveyor line 101, stacking them according to a preset stacking pattern on pallets provided by the pallet distributor 111. After stacking, the pallets are then uniformly reinforced by the shared automatic wrapping machine 112 and the cross-shaped packing machine 113. This structure achieves a high degree of sharing of equipment, space, and manpower, allowing a single production line to handle two types of packaging orders, greatly improving resource utilization.

[0027] Furthermore, a first rotating conveyor frame 114 is provided between the output end of the automatic carton opener 106 and the carton packing station of the automatic carton packer 105; a second rotating conveyor frame 115 is provided between the output end of the certificate placement mechanism 107 and the input end of the automatic carton sealer 108; and a third rotating conveyor frame 116 is provided between the output end of the first packer 109 and the input end of the second packer 110. The first rotating conveyor frame 114, the second rotating conveyor frame 115, and the third rotating conveyor frame 116 are all used to complete the rotation of the packaging box.

[0028] In this embodiment, the arrangement of the first rotating conveyor frame 114, the second rotating conveyor frame 115, and the third rotating conveyor frame 116 effectively solves the problem that after the packaging box has undergone processes such as opening, placing the certificate of conformity, and two packing, the inconsistent orientation may affect the subsequent robotic arm gripping, palletizing alignment, and the accuracy of the packing strap wrapping position.

[0029] Furthermore, the first rotating conveyor frame 114, the second rotating conveyor frame 115, and the third rotating conveyor frame 116 each include a roller conveyor frame 117, a rotating drive mechanism, a lifting mechanism, and a cross rotating frame 118. The roller conveyor frame 117 is provided with a rotating section 119, and the rollers at the rotating section 119 are arranged in a segmented structure. The rotating drive mechanism is installed below the rotating section 119, and the lifting mechanism is provided at the output end of the rotating drive mechanism. The cross rotating frame 118 is provided at the output end of the lifting mechanism.

[0030] In this embodiment, the lifting mechanism lifts the packaging box away from the conveying surface, and then the rotary drive mechanism drives the cross rotating frame 118 to complete a precise horizontal rotation. This achieves rapid, stable and precise angle adjustment of the packaging box during the conveying process, effectively ensuring the specific requirements of the box orientation for subsequent processes and improving the automation level and operational continuity of the entire line.

[0031] Furthermore, each of the rotary drive mechanisms includes a mounting base 120, a rotating assembly, and a rotating disk 121. The mounting base 120 is mounted below the rotating section 119, and the rotating disk 121 is disposed at the top of the mounting base 120. The rotating assembly is disposed inside the mounting base 120, and the output end of the rotating assembly is mechanically driven by the rotating disk 121.

[0032] In this embodiment, the rotating assembly is activated, which drives the rotating disk 121 to rotate on the mounting base 120, thereby completing the horizontal rotation of the cross rotating frame 118.

[0033] Furthermore, the rotating assembly includes a first servo motor 122 and an output gear 123. A rotating bearing 124 is provided at the top of the mounting base 120. An embedded ring 125 is provided on the side of the rotating disk 121 facing the mounting base 120. The embedded ring 125 is embedded into the interior of the rotating bearing 124. A transmission gear 126 is provided on the inner sidewall of the embedded ring 125. The first servo motor 122 is mounted on the inner bottom of the mounting base 120. The output end of the first servo motor 122 is provided with the output gear 123, and the output gear 123 meshes with the transmission gear 126.

[0034] In this embodiment, the first servo motor 122 is started, which drives the output gear 123 to rotate. Since the output gear 123 meshes with the transmission gear 126, it drives the rotating disk 121 to rotate on the end face of the mounting base 120.

[0035] Furthermore, the number of teeth of the output gear 123 is less than the number of teeth of the transmission gear 126.

[0036] In this embodiment, the transmission gear 126 reduces the output speed, making the rotation angle of the cross rotating frame 118 more controllable.

[0037] Furthermore, the lifting mechanism includes a support arm 127, a sliding arm 128, and a height adjustment assembly. The bottom of the support arm 127 is connected to the upper surface of the rotating disk 121. The sliding arm 128 is slidably disposed inside the top end of the support arm 127. Both the support arm 127 and the sliding arm 128 are hollow structures. The top end of the sliding arm 128 is mounted on the cross rotating frame 118. The height adjustment assembly is disposed at the inner bottom of the support arm 127. The output end of the height adjustment assembly is connected to the inner bottom wall of the sliding seat.

[0038] In this embodiment, the height adjustment component is activated, causing the sliding arm 128 to slide at the inner bottom of the support arm 127, thereby completing the height adjustment of the cross rotating frame 118.

[0039] Furthermore, the height adjustment assembly includes a second servo motor 129, a threaded rod 130, and a ball screw nut assembly 131. The second servo motor 129 is installed at the inner bottom of the support arm 127. The output end of the second servo motor 129 is provided with the threaded rod 130, and the ball screw nut assembly 131 is provided on the threaded rod 130. The ball screw nut assembly 131 is connected to the inner bottom wall of the sliding arm 128.

[0040] In this embodiment, the second servo motor 129 is started, which drives the threaded rod 130 to rotate. Since the ball screw nut pair 131 is connected to the inner bottom of the sliding arm 128, the sliding arm 128 is driven to slide inside the support arm 127.

[0041] Furthermore, a limit block 132 is provided at the end of the threaded rod 130 away from the second servo motor 129, and the limit block 132 is located inside the support arm 127.

[0042] In this embodiment, the limiting block 132 prevents the ball screw nut assembly 131 from falling off the threaded rod 130, and because the limiting block 132 is located inside the support arm 127, it also prevents the sliding arm 128 from falling off the support arm 127.

[0043] Furthermore, safety fences 133 are provided on the side of the packaging box conveyor line 102 and the palletizing conveyor line 103 away from the robot palletizer 104, and the safety fences 133 are located outside the working range of the robot palletizer 104.

[0044] In this embodiment, a physical barrier is constructed by setting up a safety fence 133 on the side of the packaging box conveyor line 102 and the palletizing conveyor line 103 away from the robotic palletizer 104, strictly limiting them outside the working range of the robotic palletizer 104. This design effectively prevents personnel from accidentally entering the dangerous area of ​​the robot's operation during production line operation, ensuring personal safety while also avoiding equipment downtime or production interruption due to human intervention.

[0045] Please see Figure 6 The present invention also provides a method for packaging synthetic brake shoes, applied to the automated production line for packaging synthetic brake shoes as described above, comprising the following steps: S1: The brake shoe is conveyed forward through the material conveyor line 101. At the same time, according to the packaging instructions, the boxed palletizing path or the bare part palletizing path of the brake shoe unit is selected. S2: If the boxed palletizing path is selected, the packaging box conveyor line 102 is started simultaneously, and the folded packaging box blank is unfolded and formed by the automatic box opener 106 and conveyed to the predetermined position; if the bare part palletizing path is selected, the brake shoe is conveyed to the end of the material conveyor line 101 by the material conveyor box. S3: When the unfolded packaging box arrives at the station of the automatic box packer 105, the automatic box packer 105 grabs the brake shoe units from the material conveyor line 101 according to the set number and automatically loads them into the unfolded packaging box. S4: The packaging box with brake shoes continues to move along the packaging box conveyor line 102, passing through the certificate placement mechanism 107 in sequence, where the product certificate is automatically put into the box. Then, the packaging box enters the automatic box sealing machine 108 to complete the tape sealing of the top of the box. After sealing, the packaging box passes through the first packing machine 109 and the second packing machine 110 in sequence to complete the horizontal and vertical binding and reinforcement respectively. S5: The pallet distributor 111 automatically supplies empty pallets to the palletizing station on the palletizing conveyor line 103. For the boxed palletizing path, the robot palletizer 104 picks up the packaged whole box brake shoes from the end of the packaging box conveyor line 102; for the bare part palletizing path, the robot palletizer 104 directly picks up the individual brake shoes from the end of the material conveyor line 101. S6: The robot palletizer 104 automatically stacks the whole box of brake shoes or individual brake shoes on the empty pallet according to the preset stacking pattern. The pallet after stacking is moved along the palletizing conveyor line 103 and enters the automatic top wrapping machine 112 for top film covering and stretch film wrapping around the body. S7: The wrapped pallet continues to move and enters the piercing crisscross packing machine 113 for crisscross piercing packing reinforcement. After the packing reinforcement is completed, the final packaging unit is formed and unloaded and transported out via the palletizing conveyor line 103.

[0046] In this embodiment, based on a single packaging line, intelligent judgment of packaging instructions dynamically switches and executes either carton palletizing or bare-package palletizing paths: the carton path automatically completes unpacking, packing, sealing, and strapping; the bare-package path directly transports the brake shoes to the end. Subsequently, the two paths converge, and the robotic palletizer 104 performs palletizing uniformly, sharing subsequent common post-processing steps such as stretch wrapping and sling packing. This method fundamentally solves the resource waste problem caused by maintaining two independent systems, achieving a high degree of integration of equipment, space, and processes, significantly improving packaging efficiency, flexibility, and resource utilization.

[0047] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.

After sealing, the packaging box passes through the first packing machine and the second packing machine in sequence, where it is reinforced horizontally and vertically, respectively. The pallet distributor automatically supplies empty pallets to the palletizing station on the palletizing conveyor line. For the boxed palletizing path, the robot palletizer picks up the packaged whole box brake shoes from the end of the packaging box conveyor line; for the bare part palletizing path, the robot palletizer directly picks up the individual brake shoes from the end of the material conveyor line. The robotic palletizer automatically stacks whole boxes of brake shoes or individual brake shoes on the empty pallet according to the preset stacking pattern. The pallet after stacking is moved along the palletizing conveyor line and enters the automatic top wrapping machine for top film covering and stretch film wrapping around the body. The wrapped pallet continues to move and enters the piercing crisscross packing machine for crisscross piercing and reinforcement. After the packing and reinforcement are completed, the final packaging unit is formed and transported out via the palletizing conveyor.
