Description

Technical Field

[0001] The present invention belongs to the field of mobile length monitoring, and specifically relates to a mobile length monitoring device, a profile processing system and a method thereof. Background Art

[0002] Currently, in material processing, it is often necessary to monitor the conveying distance of materials to cooperate with the use of other processing devices. At present, general sensing devices such as displacement sensors or distance sensors are generally used to achieve monitoring. However, their accuracy will be affected by various factors, and there will be errors and cumulative errors, making it difficult to achieve a high degree of synchronization between distance monitoring and processing equipment. Taking the example of obtaining data by rollers, due to the influence of different material surface smoothness or other factors on the rollers, there will be a situation of slipping, resulting in inaccurate data acquisition, which often affects subsequent processing and cannot accurately monitor the transportation length.

[0003] In addition, the automatic feeding provides the power source for the movement of materials. In actual operation, it is very difficult to synchronize the movement of materials and the fixed-length operation of processing equipment at any time. Because in specific fields, such as the production of extruded profiles, the speed is dynamically variable and can be adjusted. There is a time delay between the adjustment of machine parameters and the actual production speed of extruded profiles. This time delay will also lead to inaccurate fixed-length processing, resulting in the quality and accuracy of processing not meeting the standards. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a mobile length monitoring device, a profile processing system and a method thereof with high precision and high synchronization rate with processing equipment.

[0005] The present invention provides a mobile length monitoring device, which includes a reset seat and a material connecting member that can move relative to the reset seat. A reset member is provided on the reset seat. Among them, the reset seat can be a guide rod, a guide rail or a cylinder body. A part of the material connecting member is a sliding block, a slider or a piston, and is slidably connected to the guide rod, the guide rail or the cylinder body. One extreme position of the material connecting member on one side of the guide rail or the cylinder body is the reset state and also the initial state. In addition, the reset seat can also adopt a winding roller, and the winder and the connecting rope are used as the reset member to provide the reset ability, that is, the connecting rope is connected to the material connecting member. During reset, only the winder in the winding roller needs to work. That is, the reset seat and the material connecting member that can move relative to the reset seat described in the present invention, in cooperation with the reset member, can actively or passively reset the material connecting member to the initial position.

[0006] The material connecting member can be connected to and separated from the material. The material connecting member can be connected to and separated from the material by setting electric, pneumatic or hydraulic driven jaws through clamping and opening. When the material is ferromagnetic, the material connecting member can also be connected to and separated from the material by the energization and de-energization of an electromagnet.

[0007] It also includes a switch for monitoring whether the material connecting piece reaches the set position. The material connecting piece is connected to the material and moves synchronously with the material. When the material connecting piece moves to the set position, the switch is triggered. The switch sends a signal to the material connecting piece, and the material connecting piece separates from the material and is reset by the resetting piece. The switch assembly is a contact sensor or a push-button switch arranged on the moving path of the material connecting piece, so as to improve the timeliness and accuracy of set position monitoring.

[0008] The resetting piece is a cylinder driving piece. The piston rod of the cylinder driving piece pushes or pulls back the material connecting piece to be reset along the reset seat. After the piston rod of the cylinder driving piece pushes or pulls back the material connecting piece to be reset, it remains or is reset. When the piston rod of the cylinder driving piece pulls back the material connecting piece to be reset along the reset seat, the piston rod of the cylinder driving piece penetrates through the material connecting piece, and a pulling block is arranged on the piston rod.

[0009] The resetting piece is a reset spring. During the synchronous movement of the material connecting piece and the material, the reset spring contracts and stores energy. When the material connecting piece separates from the material, the reset spring stretches to drive the material connecting piece to be reset. When the reset seat is a guide rod or a guide rail, and a part of the material connecting piece is a sliding block or a slider, a spring limiting plate is arranged on the side of the guide rail far away from the initial position. The support plate can also be used as the spring limiting plate, and the reset spring is arranged between the spring limiting plate and the slider. When the reset seat is a cylinder body, the reset spring is arranged between the piston and the side of the cylinder body close to the set position. When the reset spring is adopted, the distance from the spring limiting plate to the switch should be greater than the length of the reset spring in the limit compression state.

[0010] There are two groups of the reset seat and the material connecting piece. The switch is connected to the two material connecting pieces. After one material connecting piece moves synchronously with the material to the set position, the switch is triggered. The switch simultaneously sends a signal to the other material connecting piece, and this material connecting piece is connected to the material.

[0011] The two groups of reset seats and material connecting pieces are arranged oppositely and share the same switch.

[0012] There are more than two groups of the reset seat, the material connecting piece and the switch. After one material connecting piece moves synchronously with the material to the set position, the switch is triggered. The switch simultaneously sends a signal to another one of them, and this material connecting piece is connected to the material.

[0013] The distances from the set positions monitored by each switch to the initial positions of each material connecting piece are different, that is, the moving stroke lengths of each material connecting piece are different, so as to realize the monitoring of various different lengths.

[0014] The reset seat includes two support plates and a guide rod disposed between the two support plates. The cylinder driving member is fixedly disposed on the support plate. The material connecting member includes a sliding block slidably engaged with the guide rod. One end of the sliding block protrudes with a fixing plate on the upper end surface or the lower end surface of the material. A clamping cylinder is fixedly disposed on the fixing plate. The output shaft of the clamping cylinder penetrates through the fixing plate and is connected with a clamping plate. The clamping plate is correspondingly disposed on the lower end surface or the upper end surface of the material. The cylinder driving member is used to push the material connecting member to reset after the material connecting member reaches the switch position. The piston rod of the cylinder driving member resets after pushing the sliding block to reset.

[0015] The present invention also provides a profile processing system, including a processing device, a profile conveying device, and a moving length monitoring device. The profile conveying device continuously conveys profiles to the processing device. The moving length monitoring device is disposed on the profile conveying path. Each time the switch of the moving length monitoring device is triggered, the processing device works once.

[0016] The present invention also provides a profile processing method, including a profile processing system, and the method includes the following steps:

[0017] S1. One of the material connecting members is connected to the profile and moves synchronously with the profile.

[0018] S2. When the moving material connecting member moves to a set position, it triggers the switch. At the same time, the switch sends a signal to the other material connecting member and the processing device. The other material connecting member is connected to the profile and moves synchronously. The processing device works to process the profile.

[0019] S3. Repeat S2.

[0020] In S2, when the material connecting member triggers the switch or after a set time, the material connecting member separates from the material and resets. The time taken from triggering the switch to resetting is within the time when the other material connecting member moves to the set position.

[0021] The beneficial effects of the present invention are as follows: By connecting the material connecting member to the material and driving the material connecting member to move through the conveying of the material, a length monitoring is completed after the material connecting member moves to a set length. In this way, during the length monitoring process, it will not be affected by the change of the material conveying speed, nor will there be a situation where the current roller data acquisition slips and results in low accuracy, or a situation where the data transmission is delayed or there is an accumulated error, etc., resulting in insufficient accuracy and synchronization rate. It greatly improves the accuracy of length monitoring and the synchronization rate with the subsequent processing device, and realizes the automatic operation of the subsequent processing device according to the conveying speed of the material in a linked manner.

[0022] Two groups of reset seats and material connectors can achieve seamless connection and sequential operation, complete the length monitoring of continuous and uninterrupted material transportation, and can realize the fixed-length monitoring and fixed-length processing of profiles during completely synchronous continuous dynamic production or transportation. It is applicable to application scenarios where materials are continuously transported, such as the continuous production of extruded profiles. It greatly improves work efficiency, while ensuring the accuracy of length monitoring and the synchronization with subsequent processing equipment. In addition, when using this method for synchronous control, there will be no cumulative error situation, improving the yield rate. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0034] As shown Figures 1-10 in the figure, the present invention provides a mobile length monitoring device, which includes a reset seat 1 and a material connecting member 3 that can move relative to the reset seat 1. A reset member is provided on the reset seat 1. The material connecting member 3 can be connected to and separated from the material 5. It also includes a switch 4 for monitoring whether the material connecting member 3 reaches a set position. The material connecting member 3 is connected to the material 5 and moves synchronously with the material 5. When the material connecting member 3 moves to the set position, the switch 4 is triggered. The switch 4 sends a signal to the material connecting member 3, and the material connecting member 3 is separated from the material 5 and reset by the reset member. Among them, the switch 4 is electrically connected to the material connecting member 3 and the subsequent processing equipment 10. After the material connecting member 3 triggers the switch 4, the switch 4 controls the separation of the material connecting member 3 from the material 5 and simultaneously controls the operation of the processing equipment 10. Among them, after the material connecting member 3 is separated from the material 5, the reset member drives the material connecting member 3 to reset to prepare for the next length monitoring of this group of material connecting members 3 and the switch 4. The reset member can be a driving member without a self-locking function, which can move following the movement of the material 5 when the material 5 drives the material connecting member 3, and actively drives the material connecting member 3 to reset during reset.

[0035] This mobile length monitoring device is used to monitor the conveying length of the material 5 and cooperate with other processing equipment 10 to enable the processing equipment 10 to perform processing after the material 5 moves a set length (that is, the length from the initial position of the material connecting member 3 to the triggered switch 5), ensuring that the conveying length of the material is synchronized with the single processing of the processing equipment 10. For example, for the cutting, punching or marking of profiles, the conveying length of the profiles can be monitored by this mobile length monitoring device, and cooperate with a cutting machine, a punching press or a marking machine to perform cutting, punching or marking after conveying a specified length. By connecting the material connecting member 3 to the material 5 and driving the material connecting member 3 to move through the conveying of the material 5, a length monitoring is completed after the material connecting member 3 moves to the set length. In this way, the length monitoring process will not be affected by the change of the conveying speed of the material 5, nor will there be a situation where the current roller data acquisition slips and results in low accuracy, or the situation where the data transmission is delayed or there is an accumulated error, etc., resulting in insufficient accuracy and synchronization rate. It greatly improves the accuracy of length monitoring and the synchronization rate with the subsequent processing equipment 10, and realizes the automatic operation of the subsequent processing equipment 10 according to the conveying speed of the material in a linked manner.

[0036] The reset member preferably adopts a cylinder driving member 7. When the reset member drives the material connecting member 3 to reset, the piston rod of the cylinder driving member 7 pushes or pulls back the material connecting member 3 to reset along the reset seat 1, and the piston rod of the cylinder driving member 7 remains or resets after pushing or pulling back the material connecting member 3 to reset.

[0037] When the piston rod of the cylinder driving member 7 pushes the material connecting member 3 to reset along the reset seat 1, the cylinder driving member 7 is arranged on the support plate 102 close to the switch 4. When the material connecting member 3 moves synchronously with the material 5 to the switch 4 and separates from the material 5, the piston rod of the cylinder driving member 7 pushes the material connecting member 3 to reset. After the material connecting member 3 is reset, the piston rod of the cylinder driving member 7 can be immediately reset; it can also maintain the limiting state to avoid the movement of the material connecting member 3 affecting the measurement accuracy. When maintaining the limiting state, at the same time when the material connecting member 3 next moves synchronously with the material 5, the piston rod of the cylinder driving member 7 quickly resets to release the limit on the material connecting member 3.

[0038] As Figure 7 shown, when the piston rod of the cylinder driving member 7 pulls back the material connecting member 3 to reset along the reset seat 1, the cylinder driving member 7 is arranged on the support plate 102 on the initial position side. The piston rod of the cylinder driving member 7 penetrates through the material connecting member 3, and a pulling block 701 is arranged on the piston rod, that is, a through hole is arranged on the material connecting member 3. The size of the piston rod is smaller than the through hole, while the size of the pulling block 701 is larger than the through hole. In the initial state, the piston rod is in the extended state, and the pulling block 701 is at the limit position close to the switch 4. When the material connecting member 3 moves synchronously with the material 5 to the switch 4 and separates from the material 5, the piston rod of the cylinder driving member 7 drives the pulling block 701 and then drives the material connecting member 3 to reset. After the material connecting member 3 is reset, the piston rod of the cylinder driving member 7 can be immediately reset; it can also maintain the limiting state to avoid the movement of the material connecting member 3 affecting the measurement accuracy. When maintaining the limiting state, at the same time when the material connecting member 3 next moves synchronously with the material 5, the piston rod of the cylinder driving member 7 quickly extends to release the limit on the material connecting member 3.

[0039] In this embodiment, during the synchronous movement of the material connecting member 3 and the material 5, it will not affect the conveying of the material 5 and reduce the impact on the conveying of the material 5.

[0040] In order to reduce costs and reduce the components to be controlled, the reset member is a reset spring. During the synchronous movement of the material connecting member 3 and the material 5, the spring contracts and stores energy. When the material connecting member 3 separates from the material 5, the spring extends to drive the material connecting member 3 to reset. In this embodiment, before the reset spring is in the extreme compression state, the material connecting member 3 can effectively trigger the switch 4. At the same time, when the reset spring extends, the reset spring can drive the material connecting member 3 to the initial state. In this embodiment, to a certain extent, it will affect the conveying of the material 5, but it can effectively reduce costs.

[0041] The switch assembly 4 is a contact sensor or a push-button switch arranged on the moving path of the material connecting member 3. The contact sensor or the push-button switch ensures reliability and reduces the failure rate.

[0042] As Figures 1-3 and Figure 7 shown, there are two sets of the reset seat 1 and the material connecting member 3. The switch 4 is connected to the two material connecting members 3. After one material connecting member 3 and the material 5 are synchronously moved to the set position, the switch 4 is triggered. The switch 4 simultaneously sends a signal to the other material connecting member 3, and this material connecting member 3 is connected to the material 5.

[0043] By providing two sets of the reset seat 1 and the material connecting member 3, the present invention can achieve seamless connection and sequential operation, complete the length monitoring of the continuous transportation of the material 5, and is applicable to the application scenarios where the material 5 is continuously transported, such as the continuous production scenario of extruded profiles. It greatly improves the work efficiency, and at the same time ensures the accuracy of the length monitoring and the synchronization with the subsequent processing equipment 10. In addition, by adopting this method for synchronous control, there will be no cumulative error situation, the yield rate is improved, and the fixed-length monitoring and fixed-length processing of the profiles during the completely synchronous continuous dynamic production or transportation can be realized.

[0044] The two sets of the reset seat 1 and the material connecting member 3 are oppositely arranged and share the same switch 4, which is more conducive to synchronizing with the processing equipment 10, reducing the equipment that needs to be linked, and improving the synchronization effect. When the two sets of the reset seat 1 and the material connecting member 3 are arranged in parallel, two sets of switches 4 are correspondingly arranged. In this embodiment, the lengths monitored by the two switches 4 can be the same or different. When they are the same, it is continuous monitoring of a fixed length. When they are different, it is alternating continuous monitoring of two lengths.

[0045] As Figure 8 shown, in the present invention, when only one switch 4 is provided, the switch 4 is electrically connected to the two sets of the material connecting members 3 and the processing equipment 10 at the same time to achieve synchronous operation and immediate feedback. As Figure 9 shown, when two or more switches 4 and material connecting members 3 are provided, the multiple switches 4 are electrically connected to each other and are all electrically connected to the processing equipment 10. At the same time, the multiple switches 4 are electrically connected to the respective material connecting members 3 to achieve continuous monitoring.

[0046] The reset seat 1, the material connecting member 3 and the switch 4 are provided with more than two groups. After one of the material connecting members 3 moves synchronously with the material 5 to a set position, the switch 4 is triggered. The switch 4 simultaneously sends a signal to another one of the material connecting members 3, and this material connecting member 3 is connected to the material 5. When there are more than two groups, sequential or irregular monitoring of different lengths can be realized. Taking the monitoring of three lengths of 50 mm, 100 mm, and 150 mm as an example, after the material connecting member 3 where 50 mm is located moves synchronously with the material 5 to a length of 50 mm, the switch 4 is triggered. The switch 4 simultaneously sends a signal to the material connecting member 3 where 100 mm or 150 mm is located to work, and so on in a cycle to achieve continuous monitoring of different lengths. In this embodiment, after the material connecting member 3 moves synchronously with the material 5 to a certain distance and triggers the switch 4, resetting needs to be completed before the next use to ensure continuous monitoring.

[0047] The distances from the set positions monitored by each switch 4 to the initial positions of each material connecting member 3 are different.

[0048] The reset seat 1 includes two support plates 102 and a guide rod 101 arranged between the two support plates 102. The cylinder driving member 7 is fixedly arranged on the support plate 102. The material connecting member 3 includes a sliding block 301 that is slidably matched with the guide rod 101. One end of the sliding block 301 is provided with a fixing plate 302 protruding from the upper end face or the lower end face of the material 5. A clamping cylinder 303 is fixedly arranged on the fixing plate 302. The output shaft of the clamping cylinder 303 penetrates through the fixing plate 302 and is connected with a clamping plate 304. The clamping plate 304 is correspondingly arranged on the lower end face or the upper end face of the material 5. The cylinder driving member 7 is used to push or pull back the material connecting member 3 after the material connecting member 3 reaches the position of the switch 4 for resetting. The piston rod of the cylinder driving member 7 maintains or resets after pushing or pulling the sliding block 301 to reset.

[0049] The present invention also provides a profile processing system, which includes a processing device 10, a profile conveying device, and a moving length monitoring device. The length monitoring device includes two groups of reset seats 1 and material connecting members 3. The profile conveying device continuously conveys profiles to the processing device 10. The moving length monitoring device is arranged on the profile conveying path. Each time the switch 4 of the moving length monitoring device is triggered, the processing device 10 works once.

[0050] The processing device 10 is synchronized with the switch 4. Each time the switch 4 is triggered, the processing device 10 works once. The prerequisite for each trigger of the switch 4 is that the profile moves a fixed length, that is, the length from the initial position of the material connecting member 3 to the position where the switch 4 is triggered.

[0051] A profile processing method, characterized in that it includes a profile processing system, and comprises the following steps:

[0052] S1. One of the material connectors 3 is connected to the profile and moves synchronously with the profile.

[0053] S2. When the moving material connector 3 moves to a set position, it triggers the switch 4. At the same time, the switch 4 sends a signal to the other material connector 3 and the processing device 10. The other material connector 3 is connected to the profile and moves synchronously, and the processing device 10 works to process the profile.

[0054] S3. Repeat S2.

[0055] In S2, when the material connector 3 triggers the switch 4 or after a set time, the material connector 3 separates from the material and resets. The time taken from triggering the switch 4 to completing the reset is within the time when the other material connector 3 moves to the set position.

[0056] As Figure 6 shown, when the reset seat is the cylinder block 8, the reset part is the piston 9. At this time, when the piston 9 is at the left limit position, the material connector 3 is at the initial position. After the material connector 3 is connected to the material 5, the piston 9 and the material connector 3 move to the right, follow the material to move to the right until the switch 4 is triggered. After the material connector 3 separates from the material 6, the piston 9 can be driven to reset by the reset spring 6 or other means.

[0057] Taking the example of setting two groups of reset seats 1 and material connectors 3, and taking the material 5 as the fixed-length drilling of the extruded profile, that is, the processing device 10 is a drilling device. The profile production device continuously produces profiles and continuously transports the profiles to the drilling device. The moving length monitoring device of the present invention is arranged between the drilling device and the profile production device. The specific working process of the present invention is as follows:

[0058] When drilling needs to start, the central controller controls the clamping cylinder 303 of one of the material connectors 3 to work. The clamping cylinder 303 drives the clamping plate 304 to approach the fixed plate 302. After the fixed plate 302 and the clamping plate 304 approach, they clamp the profile and move synchronously with the profile for a set distance. When the material connector 3 triggers the switch 4, the switch 4 controls the clamping cylinder 303 to drive the clamping plate 304 to move away from the fixed plate 302. At the same time, the switch 4 controls the drilling device to drill once, and controls the cylinder driving part 7 to immediately or between the arrival of the other group of material connectors 3 at the switch 4 to push the material connector 3 to reset. In this step, it can also be that the switch 4 sends a signal to the central controller, and the central controller then controls the clamping cylinder 303 and the drilling device to work. In order to reduce the failure frequency, simplify the circuit connection difficulty and improve the accuracy, it is preferred that the switch 4 directly controls the clamping cylinder 303 and the drilling device.

[0059] While the above-mentioned material connector 3 triggers the switch 4, the switch 4 controls the clamping cylinder 303 of another material connector 3 to work, so that it is connected to the profile and moves synchronously until the switch 4 is triggered to perform another drilling operation, and so on in a cycle, realizing the fixed-length monitoring and fixed-length processing of the profiles during the completely synchronous continuous dynamic production or conveying.
