Description

Technical Field

[0001] The utility model relates to the field of alarm controllers, in particular to a quantitative surplus alarm controller of a decreasing and increasing type. Background Art

[0002] Yarn is divided into: short-staple yarn, which is made by spinning short fibers (natural short fibers or chemical fiber cut fibers), and is divided into ring yarn, free-end spinning, self-twisted yarn, etc.; continuous filament, such as natural silk and chemical fiber filament, is divided into twisted or untwisted, smooth filament or deformed filament, etc.; short-staple and continuous filament combination yarn, such as polyester-cotton filament core-spun yarn, etc. The thread is made by combining two or more single yarns and twisting them together. Yarn is a textile product made of various textile fibers into a product of a certain fineness. It is used for weaving, rope making, thread making, knitting and embroidery. It is divided into short-staple yarn, continuous filament, etc. There are many ways to express the fineness of yarn, such as numbers, metric counts, imperial counts, fineness, etc. (see count). The twist of the yarn is expressed in the number of turns per meter or per inch.

[0003] A loom requires yarn during the weaving process. Most existing methods are to add yarn in a quantitative manner according to the amount required by the loom. When the amount of yarn does not meet the standard, the weight of the finished cloth product will not reach the set value, affecting the product quality. When the amount of yarn exceeds the standard, the weight of the finished cloth product will exceed the set value, increasing the cost. Therefore, a device for quantitatively controlling the yarn is needed. Therefore, the utility model provides a quantitative surplus alarm controller with a decreasing and increasing amount.

[0025] Example:

[0026] See also Figure 1-5 The utility model provides a technical solution: a quantitative surplus alarm controller of decremental and reverse-incremental type, comprising a base 1, a pressure weighing sensor 2 and a shell 7, the base 1 is connected with the pressure weighing sensor 2 by bolts, a support plate 3 is installed on the upper side of the pressure weighing sensor 2, the upper side of the support plate 3 is rotatably connected to a rotating seat 16, the upper end of the rotating seat 16 is detachably connected with a yarn bobbin fixing seat 6, a yarn bobbin baffle 5 is arranged on the outer wall of the upper end of the rotating seat 16, a touch screen 8 is arranged on the front side of the shell 7, a pressure weighing sensor A / D conversion module 21, an alarm module 25 and a PLC22 are integrated and installed in the shell 7, the PLC22 is electrically connected to the pressure weighing sensor A / D conversion module 21, the alarm module 25, the pressure weighing sensor 2 and the touch screen 8, and the PLC22 is electrically connected to the terminal device 24 through a relay 23.

[0027] The data obtained by the pressure weighing sensor 2 is collected through the pressure weighing sensor A / D conversion module 21 and transmitted to PLC22 for processing. PLC22 gives a specified signal according to the signal required by the programmable relay 23. When the programmable relay 23 receives the signal, it converts different pulse signals to the terminal device 24, causing the terminal device 24 to stop running and alarm through the alarm module 25. The pressure weighing sensor A / D conversion module 21 adopts a 24-bit high-precision A / D converter chip, has two analog channel inputs, and is equipped with an integrated gain programmable amplifier. The input circuit can be configured as a bridge sensor mode that provides bridge pressure.

[0028] When the pressure weighing sensor 2 detects that the object is 500 grams, the PLC 22 is set to alarm and control the terminal device 24 to stop when the object is 10 grams as needed. This function can be used for a loom. When the yarn used for the loom is about to be used up, the loom is controlled to stop, thereby performing surplus control to avoid waste of raw materials due to thread breakage in the loom and save labor costs. The terminal device 24 can be a loom, a reverse wool machine, a yarn doubling machine, a grooved drum machine and other machines that use yarn.

[0029] During use, when the quantity is set to 5Kg, the touch screen 8 starts to display O. If the pressure weighing sensor 2 measures the actual yarn to be 6Kg, after the terminal device 24 starts to run, the pressure weighing sensor 2 senses a decrease in yarn weight each time it senses a decrease in yarn weight, and sets the touch screen 8 to display the weight of the increased yarn. When the pressure weighing sensor 2 measures the actual yarn to be 1Kg, it means that the terminal device 24 has used 5kg, and the touch screen 8 displays 5kg. The PLC22 outputs an instruction to stop the terminal device 24. This process is controlled by the PLC22, that is, the touch screen 8 will display the weight after zeroing, and the displayed weight is the amount of weight loss of the object after zeroing, m displayed = m zeroed - m actual, wherein m displayed is the display value of the touch screen 8, m actual is the actual value of the object detected by the pressure weighing sensor 2, and m zeroed is the actual value of the object detected by the pressure weighing sensor 2 at the moment of zeroing, so that the weight of the product is accurate and the manufacturer's losses are reduced.

[0030] A mounting seat 4 is disposed on the upper side of the support plate 3 , and the rotating seat 16 is inserted into the mounting seat 4 and is rotatably connected thereto via a bearing.

[0031] The yarn bobbin fixing seat 6 is in a cone shape which is small at the top and large at the bottom. The middle part of the yarn bobbin fixing seat 6 is hollow. A mounting hole 17 is provided at the bottom of the yarn bobbin fixing seat 6. A threaded hole 18 which is compatible with the mounting hole 17 is provided on the upper side of the rotating seat 16. A fastening bolt 19 is installed between the yarn bobbin fixing seat 6 and the rotating seat 16. The fastening bolt 19 passes through the mounting hole 17 and is screwed with the threaded hole 18. The yarn bobbin fixing seat 6 and the rotating seat 16 are coaxially arranged, which is convenient for inserting the yarn bobbin together with the yarn, and convenient for replacing the yarn bobbin fixing seat 6 to adapt it to different yarn bobbins.

[0032] A positioning block 26 is provided at the bottom of the yarn tube fixing seat 6. The positioning block 26 and the yarn tube fixing seat 6 are integrally formed. The mounting hole 17 passes through the positioning block 26. A positioning groove 20 adapted to the positioning block 26 is opened on the upper side of the rotating seat 16, and the positioning block 26 is inserted into the positioning groove 20.

[0033] The pressure weighing sensor 2 comprises a force-bearing beam 9 , a through hole 15 is opened in the middle of the force-bearing beam 9 , and a strain gauge is installed on the force-bearing beam 9 .

[0034] The strain gauges include a first strain gauge 11, a second strain gauge 13, a third strain gauge 14 and a fourth strain gauge 12. The first strain gauge 11 and the fourth strain gauge 12 are respectively installed on the left and right sides above the force-bearing beam 9, and the second strain gauge 13 and the third strain gauge 14 are respectively installed on the left and right sides below the force-bearing beam 9. The positions of the first strain gauge 11 and the second strain gauge 13 correspond to each other up and down, and the positions of the fourth strain gauge 12 and the third strain gauge 14 correspond to each other up and down. When the force-bearing beam 9 is deformed by force, the strain gauge generates corresponding strain, which is converted into resistance change. The strain gauges are connected into a bridge, and the resistance change caused by the force will be converted into a voltage change of the measuring circuit. By measuring the value of the output voltage and then converting it, the weight of the measured object can be obtained. This is a conventional technology in the field and will not be described in detail here.

[0035] Grooves 10 are provided on both the left and right sides of the upper and lower surfaces of the load-bearing beam 9 , and the strain gauge is located between the grooves 10 on the left and right sides.

[0036] The alarm module 25 is a buzzer to avoid reminding the staff.

[0037] Working principle: The yarn and the yarn tube are placed on the yarn tube fixing seat 6. The yarn is continuously reduced during the conveying process, so that the pressure measured by the pressure weighing sensor 2 changes. When the changed pressure reaches the set value, it means that the yarn has been consumed to the target usage amount, which can effectively avoid adding too much or too little yarn. While ensuring product quality, it avoids increasing cost consumption due to excessive yarn addition. Since the yarn tube fixing seat 6 can rotate, it is convenient for the yarn tube to rotate for wire production, avoiding excessive friction that causes yarn breakage and waste of raw materials.
