Description

Technical Field

[0001] This utility model relates to the technical field of weighing devices, and more specifically, to an online weighing device for pipes. Background Technology

[0002] Pipes, as important structural materials and fluid transport media, require continuous processing through extrusion molding during their production. Taking polymer materials and metal composite materials as examples, the raw materials are heated and plasticized in an extruder, then formed into a tubular preform through an annular die, and finally formed into the final product through processes such as shaping, cooling, and traction cutting.

[0003] After the pipes are cut, they need to be separated and then weighed individually. The pipes are usually separated by dropping them off the weighing device. However, dropping the pipes directly onto the weighing device will cause vibration to the weighing device, affecting the weighing results. It will also affect the weighing sensor and shorten its service life. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology in which the weighing of pipes falling onto the weighing device will affect the weighing results, and to provide an online weighing device for pipes that avoids the impact of the weighing results caused by the pipes falling onto the weighing device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An online weighing device for pipes is provided, comprising a base, a lifting mechanism, a pallet mechanism, and a weighing mechanism. The lifting mechanism and the weighing mechanism are both mounted on the base. The pallet mechanism is connected to the output end of the lifting mechanism. The pallet mechanism is provided with a weighing groove, and the weighing mechanism passes through the weighing groove.

[0007] This utility model discloses an online pipe weighing device. Upon activation of the lifting mechanism, the pallet mechanism is raised, positioning the weighing mechanism below the weighing trough. When the pipe is dropped, it lands on the pallet mechanism without affecting the weighing mechanism. Once the pipe has completely landed on the pallet mechanism, the lifting mechanism is retracted, causing the pallet mechanism to descend and allowing the weighing mechanism to pass through the weighing trough. The pipe then lands smoothly on the weighing mechanism and separates from the pallet mechanism, enabling the weighing mechanism to weigh the pipe. By incorporating the lifting and pallet mechanisms, the pipe is first supported by the pallet mechanism upon falling before the lifting mechanism is activated, ensuring a smooth landing on the weighing mechanism for weighing. This prevents the pipe from falling directly onto the weighing device and affecting the weighing results.

[0008] Furthermore, the pallet mechanism includes a support frame, a first pallet, a second pallet, a first support mechanism, and a second support mechanism. The support frame is connected to the output end of the lifting mechanism. Both the first and second pallets are rotatably connected to the support frame. The weighing groove is located between the first and second pallets. Both ends of the first support mechanism are connected to the first pallet and the support frame, respectively. Both ends of the second support mechanism are connected to the second pallet and the support frame, respectively. By rotatably connecting both the first and second pallets to the support frame, the tilt angle of the first and second pallets can be changed, thereby facilitating the support of pipes with different outer diameters.

[0009] Furthermore, both the first and second support mechanisms are telescopic mechanisms, and both are mounted on the support frame. The output end of the first support mechanism is rotatably connected to the first pallet, and the output end of the second support mechanism is rotatably connected to the second pallet. By adjusting the telescopic mechanisms, the tilt angles of the first and second pallets can be directly changed.

[0010] Furthermore, both the first and second pallets are equipped with logistics cages underneath, and each logistics cage has a height detection system. By using these logistics cages, when the pipe weight is within acceptable limits, the first support mechanism retracts, and the pipe rolls from the first pallet into the logistics cage; when the pipe weight is insufficient, the second support mechanism retracts, and the pipe rolls from the second pallet into another logistics cage; thus, acceptable and unacceptable pipes can be automatically separated. When the height detection system detects that a logistics cage is full, it alarms to remind the operator to remove the logistics cage.

[0011] Furthermore, it also includes a guide assembly, which is mounted on the base, and the support frame is slidably connected to the guide assembly. By providing the guide assembly, the lifting and lowering of the support frame is guided, allowing the pipe to be placed stably on the weighing mechanism.

[0012] Furthermore, a limiting rod is provided at the end of the pallet mechanism. By providing the limiting rod, the pipe is prevented from falling off the end of the pallet mechanism.

[0013] Furthermore, it also includes a controller, and the limit rod is equipped with a touch sensor. Both the touch sensor and the lifting mechanism are communicatively connected to the sensor. By setting the touch sensor, when the pipe touches the touch sensor at the end, it means that the pipe has completely fallen onto the pallet mechanism. At this time, the controller controls the lifting mechanism to descend and place the pipe smoothly onto the weighing mechanism.

[0014] Furthermore, the weighing mechanism includes a first weighing component and a second weighing component, which are connected in parallel. The first and second weighing components are respectively mounted on the base along the axial direction of the pipe. Two weighing slots are provided, and the first and second weighing components respectively pass through both slots. By setting the first and second weighing components in parallel, the torsional problem caused by the weighing sensor when the weighing pipe is not in the center of the weighing pan can be avoided. This ensures that the weighing sensor is always subjected to only vertical force, effectively preventing torsional damage to the weighing sensor and significantly reducing the risk of abnormal pipe weighing.

[0015] Furthermore, both the first and second weighing components include a load cell and a weighing bracket. The load cell is mounted on the base, and the weighing bracket is connected to the input end of the load cell. The weighing bracket extends through the weighing groove, and an arc-shaped groove is provided at the end of the weighing bracket away from the base. The arc-shaped groove provides stable support for the pipe.

[0016] Furthermore, the weighing mechanism also includes an intelligent instrument and a controller. The first weighing component and the second weighing component are both communicatively connected to the intelligent instrument, and the first weighing component, the second weighing component, and the intelligent instrument are all communicatively connected to the controller. By connecting the intelligent instrument to the controller, the controller can calibrate the intelligent instrument at any time to check the accuracy of the weighing.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The present invention provides an online weighing device for pipes, which, by setting up a lifting mechanism and a support plate mechanism, allows the pipe to be supported by the support plate mechanism when it falls, and then the lifting mechanism is activated to allow the pipe to fall smoothly onto the weighing mechanism for weighing, thus avoiding the pipe falling onto the weighing device and affecting the weighing result.

[0019] 2. The present invention provides an online weighing device for pipes, which sets the first support mechanism and the second support mechanism as telescopic mechanisms, and provides a logistics cage below the first pallet and the second pallet, so as to directly classify qualified and unqualified pipes into two logistics cages.

[0020] 3. The online weighing device for pipes of this utility model, by setting up a first weighing component and a second weighing component in parallel, can avoid the torsional problem caused by the weighing sensor when the weighing pipe is not in the center of the weighing pan, so that the weighing sensor is always subjected to only vertical force, which can effectively avoid the torsional damage to the weighing sensor and effectively reduce the risk of abnormal pipe weighing.

[0027] Example 1

[0028] This embodiment is a first embodiment of an online weighing device for pipes, such as... Figure 1 As shown, the system includes a base 100, a lifting mechanism 200, a pallet mechanism 300, and a weighing mechanism 400. Both the lifting mechanism 200 and the weighing mechanism 400 are mounted on the base 100. The pallet mechanism 300 is connected to the output end of the lifting mechanism 200. The pallet mechanism 300 has a weighing groove 321, through which the weighing mechanism 400 passes. The lifting mechanism 200 can use existing lifting mechanisms, such as linear motors or cylinders.

[0029] like Figure 2As shown, the pallet mechanism 300 includes a support frame 310, a first pallet 320, a second pallet 330, a first support mechanism 340, and a second support mechanism 350. The support frame 310 is connected to the output end of the lifting mechanism 200. The first pallet 320 and the second pallet 330 are both rotatably connected to the support frame 310. The weighing trough 321 is located between the first pallet 320 and the second pallet 330. The two ends of the first support mechanism 340 are respectively connected to the first pallet 320 and the support frame 310. The two ends of the second support mechanism 350 are respectively connected to the second pallet 330 and the support frame 310. The first pallet 320 and the second pallet 330 are rotatably connected to the support frame 310, which can change the tilt angle of the first pallet 320 and the second pallet 330, thereby facilitating the support of pipes with different outer diameters. In this embodiment, the first pallet 320 and the second pallet 330 are V-shaped. After rotation, the tilt angle of the first pallet 320 and the second pallet 330 is fixed by the first support mechanism 340 and the second support mechanism 350.

[0030] It also includes a guide assembly 500, which is mounted on the base 100, and the support frame 310 is slidably connected to the guide assembly 500. By setting the guide assembly 500, the lifting and lowering of the support frame 310 is guided, so that the pipe can be placed stably on the weighing mechanism 400.

[0031] The end of the pallet mechanism 300 is provided with a limiting rod 331. By setting the limiting rod 331, the pipe is prevented from falling off the end of the pallet mechanism 300.

[0032] It also includes a controller, and a touch sensor is provided on the limit rod 331. Both the touch sensor and the lifting mechanism 200 are communicatively connected to the sensor. By setting the touch sensor, when the pipe touches the touch sensor at the end, it means that the pipe has completely fallen onto the pallet mechanism 300. At this time, the controller controls the lifting mechanism 200 to descend and place the pipe smoothly onto the weighing mechanism 400.

[0033] The working principle of the online pipe weighing device in this embodiment is as follows:

[0034] In this embodiment, the lifting mechanism 200 uses a lifting cylinder. Activating the lifting mechanism 200 raises the pallet mechanism 300, placing the weighing mechanism 400 below the weighing trough 321. The pipe is conveyed to the weighing device via a conveyor belt. There is a height difference between the conveyor belt and the weighing device, with the weighing device positioned below the conveyor belt. The pipe falls from the conveyor belt onto the weighing device, separating the cut pipe. One end of the pipe first falls onto the pallet mechanism 300, and the conveyor belt then transports the other end. The pipe falls completely onto the pallet mechanism 300 and abuts against the touch sensor on the limit rod 331. The controller receives a signal and retracts the lifting mechanism 200, causing the pallet mechanism 300 to descend, allowing the weighing mechanism 400 to pass through the weighing trough 321. At this point, the pipe falls smoothly onto the weighing mechanism 400 and separates from the pallet mechanism 300, enabling the weighing mechanism 400 to weigh the pipe. By setting up a lifting mechanism 200 and a pallet mechanism 300, the pipe is first supported by the pallet mechanism 300 when it falls, and then the lifting mechanism 200 is activated to allow the pipe to fall smoothly onto the weighing mechanism 400 for weighing, thus avoiding the pipe falling onto the weighing device and affecting the weighing result.

[0035] Example 2

[0036] This embodiment is the second embodiment of the online weighing device for pipes. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 2 and Figure 3 As shown, both the first support mechanism 340 and the second support mechanism 350 are telescopic mechanisms, and both are mounted on the support frame 310. The output end of the first support mechanism 340 is rotatably connected to the first support plate 320, and the output end of the second support mechanism 350 is rotatably connected to the second support plate 330. This telescopic mechanism can be an existing telescopic mechanism such as a linear motor or a cylinder. By adjusting the telescopic mechanism, the tilt angle of the first support plate 320 and the second support plate 330 can be directly changed, i.e., the included angle between the first support plate 320 and the second support plate 330 can be changed, thereby facilitating the support of pipes with different outer diameters.

[0037] Both the first pallet 320 and the second pallet 330 are equipped with logistics cages, each containing a height detection system. After weighing by the weighing mechanism 400, the extension lifting mechanism 200 raises the pallet mechanism 300, separating the pipe from the weighing mechanism 400 and placing it under the support of the pallet mechanism 300. By using logistics cages, when the pipe weight is within acceptable limits, the first support mechanism 340 retracts, and the pipe rolls from the first pallet 320 into the logistics cage; when the pipe weight is below acceptable limits, the second support mechanism 350 retracts, and the pipe rolls from the second pallet 330 into another logistics cage. This automatically separates acceptable and unacceptable pipes. When the height detection system detects that the logistics cage is full, it alarms to remind the operator to remove the cage. Automatic identification of acceptable and unacceptable products ensures a high product qualification rate; continuous weighing and automatic production counting also reduce the sampling step for quality inspectors, saving manpower.

[0038] Example 3

[0039] This embodiment is the third embodiment of the online weighing device for pipes. This embodiment is similar to Embodiment 1, except that, as shown in the following... Figure 2 As shown, the weighing mechanism 400 includes a first weighing component 410 and a second weighing component 420, which are connected in parallel. The first and second weighing components 410 and 420 are respectively mounted on the base 100 along the axial direction of the pipe. Two weighing slots 321 are provided, and the first and second weighing components 410 and 420 respectively pass through the two weighing slots 321. By setting the first and second weighing components 410 and 420 in parallel, the torsional problem caused by the weighing sensor when the weighing pipe is not in the center of the weighing pan can be avoided. This ensures that the weighing sensor is always subjected to only vertical force, effectively preventing torsional damage to the weighing sensor, resisting impact and vibration, correcting sensor nonlinearity errors, effectively reducing the risk of abnormal pipe weighing, improving measurement accuracy, reducing equipment maintenance frequency, and extending equipment service life.

[0040] like Figure 3 As shown, both the first weighing assembly 410 and the second weighing assembly 420 include a weighing sensor 421 and a weighing bracket 422. The weighing sensor 421 is mounted on the base 100, and the weighing bracket 422 is connected to the input end of the weighing sensor 421. The weighing bracket 422 passes through the weighing groove 321, and an arc-shaped groove is provided at the end of the weighing bracket 422 away from the base 100. The arc-shaped groove provides stable support for the pipe.

[0041] The weighing mechanism 400 also includes an intelligent instrument and a controller. The first weighing component 410 and the second weighing component 420 are both communicatively connected to the intelligent instrument, and the first weighing component 410, the second weighing component 420, and the intelligent instrument are all communicatively connected to the controller. By connecting the intelligent instrument to the controller, the controller can calibrate the intelligent instrument at any time to check the accuracy of the weighing.

[0042] The controller and intelligent instruments enable real-time online monitoring of the pipeline, providing out-of-tolerance alarms and recording data. It features automatic continuous weighing, sorting of qualified and unqualified products, and automatic production calculation, including total machine output, total output per shift, and output of qualified and unqualified products, with the ability to conduct spot checks at any time.
