Description

Technical Field

[0001] This invention relates to the field of pipe production line technology, and in particular to a conveying device for cantilever pipes. Background Technology

[0002] In the pipe cutting and processing process, existing pipe conveying devices typically use conveyor belts, robotic arms, and other equipment to transport pipes. However, these devices can only execute one specification production task at a time, following a fixed set of specifications and parameters, i.e., using a fixed-length feeding method. When producing multiple specifications in batches, manual adjustments to the parameters are required once the production quantity is sufficient. This not only results in poor production flexibility and frequent manual intervention, increasing operational complexity and error rates, but also leads to low material utilization, potential pipe waste, and increased production costs.

[0003] Existing conveying devices suffer from technical problems such as poor production flexibility, frequent manual intervention, and low material utilization because they can only perform one production task at a time according to a set of specifications and parameters. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying device for cantilever tubing, in order to solve the technical problems in related technologies where only one set of specifications and parameters can be used to perform one production task at a time, resulting in poor production flexibility, frequent manual intervention, and low material utilization.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: The present invention provides a conveying device for a cantilever tube, comprising: The system comprises a delivery component, a limiting component, and a distance measuring component. The delivery component includes a conveyor frame and a first clamping arm. The conveyor frame supports the tubing, and the first clamping arm moves the tubing along its length. The conveyor frame has a workstation notch to provide a fixed cutting position for the tubing. The limiting component includes a limiting plate movably connected to the delivery component. This limiting plate either blocks or opens the workstation notch, and its contact with the end face of the tubing provides a measurement reference for measuring the tubing's length. The distance measuring component is mounted on the conveyor frame and electrically connected to the first clamping arm. It measures the distance between the end face of the tubing and the distance measuring component to calculate the remaining length of the tubing. The comparison of the remaining length of the tubing with the production schedule list is used to select a matching production specification from the production schedule list, i.e., adjusting the feeding distance of the tubing to reduce waste.

[0006] Specifically, the ranging component includes a laser displacement sensor and a positioning bracket. The positioning bracket is mounted on the conveyor frame and positioned on the side of the pipe away from the workstation opening. The laser displacement sensor is mounted on the positioning bracket and points towards the pipe, used to measure the distance between the end face of the pipe and the laser displacement sensor.

[0007] Specifically, the ranging component further includes a first linear drive, the positioning bracket is slidably connected to the conveyor frame in the vertical direction, the first linear drive is poweredly connected to the positioning bracket, and is used to adjust the vertical height of the laser displacement sensor to match the size of the pipe, so that the laser emitted by the laser displacement sensor can be projected onto the end face of the pipe.

[0008] Specifically, the delivery assembly further includes a displacement track, which is arranged parallel to the conveyor frame. The first clamping arm is slidably connected to the displacement track to move the tube along the length of the conveyor frame.

[0009] Specifically, the first clamping arm includes a robotic arm and a robotic gripper, the robotic gripper being used to connect the pipe. One end of the robotic arm is connected to the displacement track, and the other end is connected to the robotic gripper, for placing and removing the pipe on the conveyor frame.

[0010] Specifically, the mechanical gripper includes a clamping jaw and a roller. The roller is rotatably connected to the clamping jaw and abuts against the pipe. The clamping jaw applies a clamping force to the pipe through the roller. The rotation of the roller can drive the pipe to move along its own axial direction, thereby adjusting the clamping position of the pipe.

[0011] Specifically, the delivery assembly further includes a displacement unit, which comprises a first motor, a gear, and a rack. The rack is mounted on the displacement track, and the first motor is mounted on both the first clamping arm and the second clamping arm. The gear is mounted on the output shaft of the first motor and meshes with the rack. The first motor drives the first clamping arm and the second clamping arm to move along the length direction of the displacement track through the meshing of the gear and the rack.

[0012] Specifically, the delivery assembly further includes a second clamping arm with the same structure as the first clamping arm, which is mounted on the displacement track. The first clamping arm and the second clamping arm are respectively located on both sides of the workstation notch along the length of the conveyor frame, and are used for loading and unloading the pipe, respectively.

[0013] Specifically, the limiting component further includes a second linear drive member, which is poweredly connected to the limiting plate and is used to drive the limiting plate to block or open the workstation gap.

[0014] Specifically, the delivery assembly also includes rollers, a plurality of which are rotatably connected to the conveyor frame. The rollers are configured as V-shaped wheels to provide support and positioning for the pipe.

[0015] Based on the above technical solutions, the beneficial effects of the present invention are analyzed as follows: This invention provides a conveying device for a cantilever tube, comprising: The system comprises a delivery component, a limiting component, and a distance measuring component. The delivery component includes a conveyor frame and a first clamping arm. The conveyor frame supports the tubing, and the first clamping arm moves the tubing along its length. The conveyor frame has a workstation notch to provide a fixed cutting position for the tubing. The limiting component includes a limiting plate movably connected to the delivery component. This limiting plate either blocks or opens the workstation notch, and its contact with the end face of the tubing provides a measurement reference for measuring the tubing's length. The distance measuring component is mounted on the conveyor frame and electrically connected to the first clamping arm. It measures the distance between the end face of the tubing and the distance measuring component to calculate the remaining length of the tubing. The comparison of the remaining length of the tubing with the production schedule list is used to select a matching production specification from the production schedule list, i.e., adjusting the feeding distance of the tubing to reduce waste.

[0016] In practical applications, all production specifications and quantities are entered into the equipment as a production plan list. The limiting plate is moved to block the workstation gap, and the first clamping arm places the pipe on the conveyor frame, positioned near the distance measuring component. The pipe, driven by the first clamping arm, abuts against the limiting plate, and the distance measuring component measures the distance between the pipe and its end face. The vertical distance between the distance measuring component and the limiting plate is a fixed value. The difference between the fixed distance from the limiting plate to the distance measuring component and the measured distance from the distance measuring component to the pipe's end face is the length of the pipe. The limiting plate is moved to open the workstation gap, and the first clamping arm, based on the current production specification's feeding parameters, drives the pipe through the workstation gap for cutting. After cutting, the pipe length is shortened, and the remaining length of the pipe is measured again. When the remaining length of the pipe is less than or equal to a preset multiple of the current production specification length, the remaining length of the pipe is compared with the production plan list, and the matching production specification is selected from the production plan list. This means adjusting the feeding distance of the pipe and optimizing the cutting position to reduce waste generation.

[0017] As can be seen, compared with existing technologies, this cantilever tube conveying device, when the remaining length of the tube is less than or equal to a preset multiple of the current production specification length, compares the remaining length of the tube with the production plan list, changes the production specification based on the production plan list, and adjusts the cutting position, thereby reducing waste generation and improving material utilization. This overcomes the technical problems of existing conveying devices, which can only execute one specification production task according to one set of specification parameters at a time, resulting in poor production flexibility, frequent manual intervention, and low material utilization.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0023] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Existing conveying devices suffer from technical problems such as poor production flexibility, frequent manual intervention, and low material utilization because they can only perform one production task at a time according to a set of specifications and parameters.

[0025] In view of this, the present invention provides a conveying device for a cantilever tube, comprising: The system comprises a delivery assembly 100, a limiting assembly 200, and a ranging assembly 300. The delivery assembly 100 includes a conveyor frame 110 and a first clamping arm 120. The conveyor frame 110 supports the tubing 001, and the first clamping arm 120 moves the tubing 001 along its length. The conveyor frame 110 has a workstation notch 101, which provides a fixed cutting station for the tubing 001. The limiting assembly 200 includes a limiting plate 210, which is movably connected to the delivery assembly 100. The limiting plate 210 blocks or opens the workstation notch 101, and its contact with the end face of the tubing 001 provides a measurement reference for measuring the length of the tubing 001. The ranging assembly 300 is mounted on the conveyor frame 110 and electrically connected to the first clamping arm 120. It measures the distance between the end face of the tubing 001 and the ranging assembly 300 to calculate the remaining length of the tubing 001. The comparison between the remaining length of pipe 001 and the production plan list is used to select the matching production specifications from the production plan list, that is, to adjust the feeding distance of pipe 001 to reduce the generation of waste.

[0026] In summary, the cantilever tube conveying device provided by the present invention can achieve the following technical effects: When the remaining length of tube 001 is less than or equal to a preset multiple of the current production specification length, the conveying device of this cantilever tube compares the remaining length of tube 001 with the production plan list. Based on the production plan list, it changes the production specification and adjusts the cutting position, thereby reducing waste and improving material utilization. This overcomes the technical problems of existing conveying devices, which can only execute one specification production task according to one set of specification parameters at a time, resulting in poor production flexibility, frequent manual intervention, and low material utilization.

[0027] The following combination Figures 1 to 8 The structure and shape of the cantilever tube conveying device provided in this embodiment will be described in detail: Regarding the structural composition of the ranging component 300, specifically: In this embodiment, the ranging component 300 includes a laser displacement sensor 310 and a positioning bracket 320. The positioning bracket 320 is mounted on the conveyor frame 110 and positioned on the side of the pipe 001 away from the workstation notch 101. The laser displacement sensor 310 is mounted on the positioning bracket 320 and points towards the pipe 001, used to measure the distance between the end face of the pipe 001 and the laser displacement sensor 310.

[0028] Regarding how the ranging component 300 adapts to the different sizes of pipe 001, specifically: The ranging component 300 also includes a first linear drive 330. The positioning bracket 320 is slidably connected to the conveyor frame 110 in the vertical direction. The first linear drive 330 is poweredly connected to the positioning bracket 320 and is used to adjust the vertical height of the laser displacement sensor 310 to match the size of the pipe 001, so that the laser emitted by the laser displacement sensor 310 can be projected onto the end face of the pipe 001.

[0029] To enable the pipe 001 to move along the length of the conveyor frame 110, in this embodiment, the delivery assembly 100 further includes a displacement track 130, which is arranged parallel to the conveyor frame 110. The first clamping arm 120 is slidably connected to the displacement track 130 to drive the pipe 001 to move along the length of the conveyor frame 110.

[0030] Regarding the structural composition of the first clamping arm 120, specifically: The first gripping arm 120 includes a robotic arm 121 and a robotic gripper 122, the latter used to connect the pipe 001. One end of the robotic arm 121 is connected to the displacement track 130, and the other end is connected to the robotic gripper 122, used to place and remove the pipe 001 on the conveyor frame 110. The robotic arm 121 includes multiple sequentially hinged arm sections, each hinge point equipped with a second motor to drive each arm section to complete the complex conveying action of the pipe 001.

[0031] To assist the pipe 001 in moving along the length of the conveyor frame 110, in this embodiment, the mechanical gripper 122 includes a clamping gripper 1221, a roller 1222, and a third motor 1223. The third motor 1223 is mounted on the clamping gripper 1221, and the roller 1222 is mounted on the output shaft of the third motor 1223 and abuts against the pipe 001. The clamping gripper 1221 applies a clamping force to the pipe 001 through the roller 1222. The rotation of the roller 1222 can drive the pipe 001 to move along its own axial direction, thereby adjusting the clamping position of the pipe 001.

[0032] Regarding how the movement of the first clamping arm 120 and the second clamping arm 140 along the displacement track 130 is driven, in this embodiment, the delivery assembly 100 further includes a displacement unit 150, which includes a first motor 151, a gear 152, and a rack 153. The rack 153 is mounted on the displacement track 130, and the first clamping arm 120 and the second clamping arm 140 are both equipped with the first motor 151. The gear 152 is mounted on the output shaft of the first motor 151 and meshes with the rack 153. The first motor 151 drives the first clamping arm 120 and the second clamping arm 140 to move along the length direction of the displacement track 130 through the meshing of the gear 152 and the rack 153.

[0033] To improve the conveying efficiency of pipe 001, in this embodiment, the delivery assembly 100 further includes a second clamping arm 140 with the same structure as the first clamping arm 120, and the second clamping arm 140 is mounted on the displacement track 130. The first clamping arm 120 and the second clamping arm 140 are respectively disposed on both sides of the workstation notch 101 along the length direction of the conveyor frame 110, and are used for loading and unloading pipe 001 respectively.

[0034] Specifically, regarding how the limit plate 210 is driven: The limiting component 200 also includes a second linear drive 220, which is poweredly connected to the limiting plate 210 and is used to drive the limiting plate 210 to block or open the workstation gap 101.

[0035] To facilitate the transport of pipe 001 on conveyor frame 110, in this embodiment, the delivery component 100 further includes rollers 160. Multiple rollers 160 are rotatably connected to conveyor frame 110. The rollers 160 are configured as V-shaped wheels to support and position pipe 001.

[0036] In summary, the specific working process of the cantilever tube conveying device provided in this embodiment is as follows: All production specifications and quantities are entered into the equipment as a production plan list. The second linear drive 220 drives the limiting plate 210 to block the workstation gap 101. The first clamping arm 120 places the tube 001 on the conveyor frame 110 and positions it on the side of the limiting plate 210 near the laser displacement sensor 310. Through the meshing of the gear 152 and the rack 153, the tube 001 is driven to abut against the limiting plate 210. The drive roller 1222 rotates to adjust the clamping position of the tube 001. The first linear drive 330 drives the positioning bracket 320 to move the laser displacement sensor 310 vertically to adjust the vertical height of the laser displacement sensor 310 to match the size of the tube 001. This allows the laser emitted by the laser displacement sensor 310 to be projected onto the end face of the tube 001. The laser displacement sensor 310 measures the distance to the end face of the tube 001 by receiving the reflected laser light. The vertical distance between the laser displacement sensor 310 and the limiting plate 210 is a fixed value. The difference between the fixed distance from the limiting plate 210 to the laser displacement sensor 310 and the measured distance from the laser displacement sensor 310 to the end face of the pipe 001 is the current length of the pipe 001.

[0037] The second linear drive component 220 drives the limiting plate 210 to open the workstation notch 101. The first clamping arm 120, according to the feeding parameters of the current production specification, drives the pipe 001 through the workstation notch 101 for cutting. After the cutting operation is completed, the length of the pipe 001 is shortened, and the remaining length of the pipe 001 is remeasured. When the remaining length of the pipe 001 is less than or equal to a preset multiple of the current production specification length, the remaining length of the pipe 001 is compared with the production plan list. The matching production specification is selected from the production plan list, that is, the feeding distance of the pipe 001 is adjusted, and the cutting position is optimized to reduce waste generation.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
