Description

Technical Field

[0001] The utility model relates to the field of textile tube unloading machines, in particular to a tube unloading machine tilt warning and calibration device. Background Art

[0002] The weaving processing plants in the textile industry need to use unloading machines to load and unload yarn bobbins before and after dyeing. After the production of yarn balls is completed, the yarn balls need to be weighed after unloading with the help of unloading machines. The weighing method of yarn balls on unloading machines is usually to manually place the yarn balls on a fixed scale. Due to the heavy weight of the yarn balls, the manual weighing work is greatly increased, and the time interval of manual weighing is not very accurate, which reduces the accuracy of yarn ball weighing. In the current use scenario of unloading machines, due to the harsh on-site use environment, the workstations are different each time the unloading machine is used, and the number of unloaded bobbins is different, which makes it difficult for the machine to achieve dynamic balance and reduce mechanical loss. Once the unloading machine is found to be skewed, there is often irreversible damage to the machine, which leads to the replacement of expensive parts, and the replaced parts often do not reach the designed service life. To this end, we designed a tilt warning and calibration device for unloading machines. Utility Model Content

[0003] In order to solve the technical problem of weighing yarn balls quickly and ensuring that they are not skewed, the utility model provides a tilt warning and weighing device for a bobbin unloading machine.

[0004] The utility model is implemented by the following technical scheme: a barrel unloading machine tilt warning and calibration device, including a barrel unloading machine, a barrel unloading gripper is arranged on the barrel unloading machine, the barrel unloading gripper includes a horizontal plate and a gripper plate one and a gripper plate two arranged at the left and right ends of the horizontal plate, a weighing plate is suspended on the upper surface of the horizontal plate, a weighing sensor is installed at the lower end of the horizontal plate, and the weighing plate is connected to the weighing sensor, a three-axis MEMS gyroscope is installed on the outward side of the gripper plate one, and a three-axis MEMS accelerometer is installed on the outward side of the gripper plate two.

[0005] As a further improvement of the above scheme, four circular holes in a rectangular distribution are provided on the upper surface of the horizontal plate on the barrel unloading grab plate of the barrel unloading machine, and four supporting columns in a rectangular structure are provided on the lower surface of the weighing plate. The supporting columns pass through the circular holes and are placed underneath them, and there is a spacing of 3-5mm between the weighing plate and the upper surface of the horizontal plate. The yarn ball is placed above the weighing plate, and all the weight of the yarn ball is concentrated on the weighing sensor, so that the actual weight of the yarn ball can be accurately weighed.

[0006] As a further improvement of the above scheme, the outer diameter of the support column is smaller than the inner diameter of the circular hole. The support column is slidably arranged in the circular hole, and the outer ring surface of the support column does not contact the inner wall of the circular hole. The support column will not be interfered by the outside world, thereby ensuring the accuracy of weighing.

[0007] As a further improvement of the above scheme, a mounting frame is installed below the unloading barrel gripper, the weighing sensor is installed above the mounting frame, and an abutment plate is installed on the weighing sensor, the upper end surface of the abutment plate is connected to the lower end of the support column, and after the yarn ball is placed above the weighing plate, the weight of the yarn ball can be directly transferred to the weighing sensor, thereby improving the weighing accuracy.

[0008] As a further improvement of the above scheme, a mounting plate is installed on the outward surface of the grab plate one and the grab plate two, and the outward surface of the mounting plate is a planar structure. The three-axis MEMS gyroscope and the three-axis MEMS accelerometer are installed on the grab plate one and the grab plate two through the mounting plate. The outward side of the grab plate one and the grab plate two is an arc surface. The provided mounting plate facilitates fixing the three-axis MEMS gyroscope and the three-axis MEMS accelerometer on the grab plate one and the grab plate two.

[0009] As a further improvement of the above solution, the weighing sensor is electrically connected to the PLC controller via a signal line, and can weigh the weight of the yarn bobbin in real time.

[0010] As a further improvement of the above scheme, the PLC controller includes a central processing unit CPU, and the central processing unit CPU is also provided with an RJ45 network circuit and a serial port circuit to facilitate connection with external components, and the RJ45 network circuit can realize remote data transmission.

[0011] As a further improvement of the above solution, the three-axis MEMS gyroscope and the three-axis MEMS accelerometer are electrically connected to the scalable digital motion processor DMP, and the scalable digital motion processor DMP is electrically connected to the PLC controller. The scalable digital motion processor DMP performs posture solution to calculate the yarn taking posture of the unloading machine in real time to ensure that it will not be skewed.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model sets a horizontal weighing plate on the unloading gripper of the unloading machine, and the weighing plate contacts the weighing sensor through the supporting column, so that the yarn ball can be weighed and detected during the sand taking process, and the three-axis MEMS gyroscope and the three-axis MEMS accelerometer can be used to ensure that the weighing plate and the yarn ball are in a horizontal state in real time when the yarn is taken, thereby ensuring the accuracy of weighing;

[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] Example:

[0025] Please combine Figure 1-Figure 6 A barrel unloading machine tilt warning and calibration device of the present embodiment includes a barrel unloading machine 1. A barrel unloading gripper is arranged on the barrel unloading machine 1. The barrel unloading gripper includes a horizontal plate 11 and a gripping plate 12 and a gripping plate 2 13 arranged at the left and right ends of the horizontal plate 11. A weighing plate 4 is suspended on the upper end surface of the horizontal plate 11. A weighing sensor 5 is installed at the lower end of the horizontal plate 11, and the weighing plate 4 is connected to the weighing sensor 5. A three-axis MEMS gyroscope 3 is installed on the outward side of the gripping plate 12, and a three-axis MEMS accelerometer 7 is installed on the outward side of the gripping plate 2 13.

[0026] The upper surface of the horizontal plate 11 on the barrel unloading grab plate of the barrel unloading machine 1 is provided with four circular holes in a rectangular distribution, and the lower surface of the weighing plate 4 is provided with four supporting columns 41 in a rectangular structure. The supporting columns 41 pass through the circular holes and are placed thereunder, and there is a spacing of 3-5mm between the weighing plate 4 and the upper surface of the horizontal plate 11. The yarn ball is placed above the weighing plate 4, and all the weight of the yarn ball is concentrated on the weighing sensor 5, so that the actual weight of the yarn ball can be accurately weighed.

[0027] The outer diameter of the support column 41 is smaller than the inner diameter of the circular hole. The support column 41 is slidably arranged in the circular hole, and the outer ring surface of the support column 41 does not contact the inner wall of the circular hole. The support column 41 will not be interfered by the outside world, thereby ensuring the accuracy of weighing.

[0028] A mounting frame 6 is installed below the unloading barrel gripper, a weighing sensor 5 is installed above the mounting frame 6, and an abutment plate 42 is installed on the weighing sensor 5. The upper end surface of the abutment plate 42 is connected to the lower end of the support column 41. After the yarn ball is placed above the weighing plate 4, the weight of the yarn ball can be directly transferred to the weighing sensor 5, thereby improving the weighing accuracy.

[0029] The outward surfaces of grab plate 1 12 and grab plate 2 13 are both installed with mounting plates 2, and the outward surfaces of mounting plates 2 are planar structures. The three-axis MEMS gyroscope 3 and the three-axis MEMS accelerometer 7 are installed on grab plate 1 12 and grab plate 2 13 through the mounting plates 2. The outward surfaces of grab plate 1 12 and grab plate 2 13 are arc-shaped surfaces. The mounting plates 2 are provided to facilitate fixing the three-axis MEMS gyroscope 3 and the three-axis MEMS accelerometer 7 on grab plate 1 12 and grab plate 2 13.

[0030] The weighing sensor 5 is electrically connected to the PLC controller via a signal line, and can weigh the weight of the yarn bobbin in real time.

[0031] The PLC controller includes a central processing unit CPU, and the central processing unit CPU is also provided with an RJ45 network circuit and a serial port circuit, which is convenient for connection with external components, and the RJ45 network circuit can realize remote data transmission.

[0032] The three-axis MEMS gyroscope 3 and the three-axis MEMS accelerometer 7 are both electrically connected to the expandable digital motion processor DMP, and the expandable digital motion processor DMP is electrically connected to the PLC controller. The expandable digital motion processor DMP performs posture resolution and can calculate the yarn taking posture of the unloading machine 1 in real time to ensure that it will not be skewed.

[0033] The implementation principle of the tilt warning and weighing device of the unloading machine 1 in the embodiment of the present application is as follows: when the unloading machine 1 is taking yarn, its unloading gripper will move forward and place the yarn ball in the form of a tube above the weighing plate 4, then the gripper plate 1 12 and the gripper plate 2 13 will close and fix the yarn tube, and then the unloading gripper will shrink, descend and turn 180 degrees to put down the yarn tube (the unloading gripper can be raised and lowered, rotated 360 degrees and moved forward and backward);

[0034] During the yarn taking process, the three-axis MEMS gyroscope 3 and the three-axis MEMS accelerometer 7 will monitor the movement of the unloading gripper in real time and calculate the current posture, and send the calculated posture to the PLC controller of the unloading machine 1 in real time. If the calculation terminal initialization signal is not received, the system will shut down and prompt manual inspection, and the PLC controller will control the device to check whether the posture information calculated by the terminal is received when going to take yarn or put yarn, and save the information. If it is accepted correctly, it will proceed to the next step. After receiving the posture information, compare the teaching position and the posture information of the key steps. If the posture deviation is too large, the system will shut down and prompt manual inspection. In the process of taking yarn, the posture information will also be read in real time. If the posture deviation is too large and the time is too long, the system will also shut down and prompt manual inspection.

[0035] By arranging a horizontal weighing plate 4 on the unloading gripper of the unloading machine 1, the weighing plate 4 contacts the weighing sensor 5 through the supporting column 41, and the yarn ball can be weighed and detected during the sand taking process, and the three-axis MEMS gyroscope 3 and the three-axis MEMS accelerometer 7 are arranged in cooperation, so that it can be ensured in real time that the weighing plate 4 and the yarn ball are in a horizontal state when the yarn is taken, thereby ensuring the accuracy of weighing;

[0036] By arranging a three-axis MEMS gyroscope 3 and a three-axis MEMS accelerometer 7 on the barrel unloading gripper, it is possible to determine the real-time posture of the barrel unloading machine 1 and provide intuitive data display on whether the barrel unloading machine 1 is tilted or not.

[0037] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
