Description

Technical Field

[0001] The present invention relates to the field of warp knitting machines, in particular to a jacquard jacquard and a control device for the jacquard jacquard. Background Art

[0002] Conventional wired jacquard jacquard machines typically consist of a main controller, relay card, baseboard, power supply, and driver card (P8 board). In use, the relay card has one set of pull-out codes for grouping. Each relay card manages 32 driver cards, and each driver card has two sets of pull-out codes. These two sets of pull-out codes use different pull-out combinations. The ultimate purpose of these pull-out codes is to determine the jacquard jacquard's position in the entire data chain, that is, to determine which process data the jacquard jacquard jacquard corresponds to. Taking the 138-inch E24 single jacquard machine as an example, this article briefly introduces the role of pull-out codes in the process data allocation process:

[0003] 1. A total of 208 E24 jacquards are required for a 138-inch single jacquard, with a total needle count of 3312.

[0004] 2. The master controller sends a pattern data packet each time the machine moves through a row or column. This data packet consists of several bytes, including 414 bytes of process data, totaling 3312 bits. Each bit corresponds to one pin. Each bit can be 0 or 1, corresponding to the pin's left or right swing. Under normal circumstances, the pattern data bits correspond one-to-one with the actual physical pin positions: the first bit corresponds to pin 1, the second bit to pin 2, and so on.

[0005] 3. Each relay card can control 32 driver cards, each controlling 32 pins (two jacquards), so each relay card can control a total of 1024 pins. The relay card has a DIP switch, typically a 4-position DIP switch with settings ranging from 0000 to 1111. Software on the relay card identifies the DIP switch value. If it's 0, the software intercepts bits 0 to 1023 of the data packet; if it's 1, it intercepts bits 1024 to 2047; if it's 2, it intercepts bits 2048 to 3071; if it's 3, it intercepts bits 3072 to 4095, and so on. Since a 138-inch machine has a maximum of 3312 pins, by the time DIP switch reaches 3, the number of pins is sufficient. Therefore, a 138-inch machine requires at most four relay cards. The relay cards are typically switched in ascending order.

[0006] 4. The relay card transmits the 1024-bit data it has intercepted using its own pull-up codes to the driver card. The driver card is mounted on the baseboard. Each driver card has two sets of pull-up codes, which function similarly to the pull-up codes on the relay card. The driver card uses these two sets of pull-up codes to determine which 32 bits of the 1024-bit data it intercepts. For example, if the pull-up code combination is 1, the current driver card intercepts data from bits 0 to 31. If the pull-up code combination is 2, it intercepts data from bits 32 to 63, and so on. Generally, the pull-up codes on the driver card are also sequentially incremented, and this process is completed by hardware.

[0007] 5. Through the code setting of the relay card and the driver card, the bits in the process data are mapped one-to-one to the actual needle position, realizing the control of the process data to the actual needle position.

[0008] The shortcomings of the above method are: when installing or replacing the jacquard, the pull-out code needs to be correctly set. If the setting is incorrect, the data corresponding to the jacquard will be incorrect, which will cause the jacquard to operate abnormally. This requires the user to have a correct understanding of the pull-out code. However, since each relay card and driver card needs to be correctly set for pull-out code, errors are inevitable. Summary of the Invention

[0009] The present invention provides a jacquard jacquard and a control device for the jacquard jacquard, which mainly aims to overcome the defect that the existing jacquard setting dial requires additional dial setting, but the user is prone to setting errors when setting the dial by himself.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A jacquard jacquard comprises at least one wireless jacquard with a plurality of jacquard needles and at least one jacquard driver. The jacquard driver comprises at least one driving circuit for driving the jacquard needles to swing, and the jacquard driver is not equipped with a code dial.

[0012] Furthermore, the jacquard driver also includes a plurality of shift registers, which are electrically connected to the corresponding drive circuits. The shift registers are used to receive pattern data and shift the pattern data bit by bit under the action of a clock signal. After all pattern data are shifted, the current data is latched and output to the drive circuit.

[0013] Furthermore, the shift registers are electrically connected in series.

[0014] A control device for a jacquard jacquard, comprising at least one controller, at least one first connector, and at least one second connector, wherein the input end of the first connector is electrically connected to the output end of the controller, the output end of the first connector is electrically connected to the jacquard driver of the jacquard jacquard, the output end of the jacquard driver is electrically connected to the input end of the second connector, and the output end of the second connector is electrically connected to the input end of the controller. When in use, the controller sends pattern data to the corresponding jacquard jacquard through the first connector for jacquard yarn guiding, and the jacquard jacquard transmits pattern data back to the controller through the second connector for fault detection. The jacquard jacquard is the jacquard jacquard described above.

[0015] Compared with the prior art, the beneficial effects produced by the present invention are:

[0016] 1. The present invention has a simple structure and strong practicality. By setting the jacquard drive without a dial, the user does not need to set the dial separately, which solves the problem of dialing the wrong dial and avoids the situation of the dial being accidentally touched. After removing the dial, the weight of the jacquard drive is reduced and the space occupied by the dial in the jacquard drive is reduced, achieving a two-pronged effect.

[0017] 2. In the present invention, by setting a shift register to receive pattern data, the jacquard drive can normally drive the jacquard needle to swing according to the setting of the pattern data, thereby improving the stability of the jacquard drive.

[0018] 3. In the present invention, a controller is set to send the selected pattern data to the corresponding jacquard jacquard through the first connector, so that the jacquard jacquard does not need to be set with a dialer to intercept the pattern data. The jacquard driver obtains the pattern data and drives the jacquard jacquard to perform jacquard yarn guiding. After use, the pattern data is transmitted back to the controller through the second connector for detection. When the entire control device is connected normally, the pattern data and power sent from the first connector can be passed through the corresponding jacquard jacquard and finally returned to the controller through the second connector, indicating that the entire circuit is normal. If any node in the middle is open or faulty, the controller will receive an erroneous signal or no signal at all. At this time, the controller will immediately stop the machine operation and directly troubleshoot the fault, which plays the role of fault detection and achieves the effect of killing two birds with one stone.

[0032] Reference Figure 1 and Figure 4The shift register 10 is electrically connected to the corresponding drive circuit 188. The shift register 10 is used to receive pattern data and shift the pattern data bit by bit under the action of a clock signal. After all pattern data has been shifted, the current data is latched and output to the drive circuit 188. In this embodiment, four shift registers 10 can be connected in series to form a shift register circuit. Each shift register 10 is an 8-bit serial input and parallel output shift register, thereby achieving 32-bit data input and parallel output in each wireless jacquard 11. The shift register 10 model can be 74HC595.

[0033] Bit is the abbreviation of binary digit. In the binary number system, each 0 or 1 is a bit, which is the smallest unit of data storage. 8 bits are called a byte.

[0034] Reference Figure 1 and Figure 4 By setting the shift register 10 to receive the pattern data, the jacquard driver 112 can normally drive the jacquard needle to swing according to the setting of the pattern data, thereby improving the stability of the jacquard driver 112.

The first power port 114 is provided on the left side of the third printed circuit board 113 by welding, and the second power port 115 is provided on the right side of the third printed circuit board 113 by welding. The plug component 300 is provided on the front of the third printed circuit board 113 by welding. After the first power port 114, the second power port 115, the plug component 300 and the third printed circuit board 113 are electrically connected together by welding, they form an inseparable whole. The third printed circuit board 113 is replaceably mounted on the rear portion of the third base 111 using screws.

[0037] Reference Figure 2 and Figure 3 The control device includes at least one controller 12 , at least one first connector 13 and at least one second connector 14 .

[0038] Reference Figure 2 and Figure 3 The input end of the first connector 13 is electrically connected to the output end of the controller 12, the output end of the first connector 13 is electrically connected to the jacquard driver 112 of the jacquard jacquard, the output end of the jacquard driver 112 is electrically connected to the input end of the second connector 14, and the output end of the second connector 14 is electrically connected to the input end of the controller 12. When in use, the controller 12 sends pattern data to the corresponding jacquard jacquard through the first connector 13 for jacquard yarn guiding, and the jacquard jacquard returns pattern data to the controller 12 through the second connector 14 for fault detection.

[0039] Reference Figure 2 and Figure 3 By setting the controller 12 to send the selected pattern data to the corresponding jacquard jacquard through the first connector 13, the jacquard jacquard does not need to set a dialer to intercept the pattern data. The jacquard driver 112 obtains the pattern data and drives the jacquard jacquard to perform jacquard yarn guiding. After use, the pattern data is transmitted back to the controller 12 through the second connector 14 for detection. When the entire control device is connected normally, the pattern data and power supply sent from the first connector 13 can pass through the corresponding jacquard jacquard and finally return to the controller 12 through the second connector 14, indicating that the entire circuit is normal. If any node in the middle is open or faulty, the controller 12 will receive an erroneous signal or no signal at all. At this time, the controller 12 will immediately stop the machine operation and directly troubleshoot the problem, which plays the role of fault detection and achieves the effect of killing two birds with one stone.

[0040] Reference Figure 2 and Figure 3 The controller 12 includes at least one single-chip microcomputer 19 , at least one high-speed driver chip 20 , at least one 180V and 24V power management circuit 21 , and at least one fault detection circuit 22 .

[0041] Reference Figure 2 and Figure 3 The single-chip microcomputer 19 is used to output the pattern data signal, the clock signal and the latch signal respectively. The output end of the single-chip microcomputer 19 is electrically connected to the input end of the high-speed driver chip 20. The high-speed driver chip 20 is used to convert the 3.3V signal output by the single-chip microcomputer 19 into a 5V signal. The output end of the high-speed driver chip 20 is electrically connected to the input end of the first connector 13.

[0042] Reference Figure 2 and Figure 3By setting up the single chip microcomputer 19 to pass the pattern data, clock signal CLK, latch signal LCK and other signals through the high-speed driver chip 20 circuit, the 3.3V signal is converted into a 5V signal, the signal transmission distance is increased, the signal anti-interference is improved, the signal can be transmitted stably, and the stable operation of the jacquard is guaranteed.

When the fault detection circuit 22 detects that the pattern data fed back through the second connector 14 is abnormal, the signal is fed back to the single-chip microcomputer 19, and the single-chip microcomputer 19 determines that it is a fault. At this time, the single-chip microcomputer 19 controls the power management circuit 21 to turn off the 180V and 24V power supplies respectively, so that the jacquard jacquard stops working.

[0044] Reference Figure 2 and Figure 3 The fault detection circuit 22, when detecting that the feedback signal from the jacquard is abnormal, feeds back the signal to the single chip microcomputer 19, and the single chip microcomputer 19 determines it as a fault. The single chip microcomputer 19 controls the 180V and 24V power management circuits 21, turns off the 180V and 24V power supplies, and stops the jacquard from working.

[0045] Reference Figure 2 and Figure 3 , 180V and 24V power management circuit 21, receives the control signal of the microcontroller 19, turns on or off the 180V and 24V power supplies

[0046] Reference Figure 1 、 Figure 2 and Figure 3 In this embodiment, except for the input and output of the pattern data being independent, other signals are connected in parallel.

[0047] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The first connector 13 includes at least one first base 30 without the piezoelectric jacquard element 102 mounted thereon, at least one first printed circuit board 16 disposed on the first base 30 , and a plurality of first signal lines 15 disposed on the first printed circuit board 16 .

The output end of the first printed circuit board 16 is electrically connected to the input end of the jacquard drive 112 in a detachable manner. The bottom of the first base 30 can be replaceably mounted on the left side of a comb mounting portion 101.

[0049] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The output end of the first printed circuit board 16 can be electrically connected to the third printed circuit board 113 of the jacquard drive 112 using a flexible contact type, thereby converting the signal line from the controller 12 into a side connection in the form of a wiring harness and connecting it to the first jacquard.

[0050] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The second connector 14 includes at least one second base 31 on which the piezoelectric jacquard element 102 is not mounted, at least one second printed circuit board 18 disposed on the second base 31 , and a plurality of second signal lines 17 disposed on the second printed circuit board 18 .

The output end of the second printed circuit board 18 is electrically connected to the input end of the jacquard drive 112 in a detachable manner. The bottom of the second base 31 can be replaceably mounted on the right side of a comb mounting portion 101.

[0052] Reference Figure 1 The data input signal line 23 and the data output signal line 28 are respectively used to transmit pattern data.

[0053] Reference Figure 5 The first base 30 and the second base 31 are both bases commonly used in the jacquard field, and can be bases with the same appearance as the third base 111. The first base 30, the second base 31 and the third base 111 can all be made of aluminum-magnesium alloy material, magnesium alloy material or aluminum alloy material.

[0054] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5The principle of this embodiment is described below: Assuming that the control device has three jacquards, each wireless jacquard with 116 pins requires 32 bits of data for control. The following describes how these three jacquards can automatically obtain accurate data without pulling the code.

[0055] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 Each wireless jacquard has 116 pins. Since each pin drive circuit 188 has two input terminals, 32-bit data is required for control.

[0056] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 , the controller 12 sends three 32-bit data. Assume that the final correct data arrangement is: the first 32-bit corresponds to wireless jacquard 1, the second corresponds to wireless jacquard 2, and the third corresponds to wireless jacquard 3.

[0057] 1. The controller 12 first sends the third 32-bit data. After 32 clocks, this 32-bit data is shifted into the wireless jacquard 1.

[0058] 2. The controller 12 then sends the second 32-bit data. After 32 clocks, due to the characteristics of the shift register 10, the wireless jacquard 1 shifts the data 3 to the wireless jacquard 2. The wireless jacquard 1 now stores the data 2.

[0059] 3. The controller 12 finally sends the first 32-bit data. After 32 clocks, data 3 of wireless jacquard 2 is moved to wireless jacquard 3, data 2 of wireless jacquard 1 is moved to wireless jacquard 2, and wireless jacquard 1 saves data 1.

[0060] 4. Finally, the controller 12 controls the latch signal, and each jacquard latches its corresponding data and outputs it to its own drive circuit 188, completing the conversion of data into needle position action.

[0061] 5. As can be seen from the above process, after using this control device, there is no need to remove the code; the data will automatically correspond to the jacquard position. For example, if a wireless jacquard 1 is damaged and replaced, as long as the installation position of the wireless jacquard 1 remains unchanged, the corresponding relationship between the data and the jacquard will not change, thus achieving plug-and-play functionality without removing the code. The above example uses three jacquards only to illustrate the function, not to indicate that there are only three jacquards. The number of jacquards can be increased as needed, but the overall process remains unchanged.

[0062] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5, Automatic fault detection: When the entire system is connected normally, the signal or power sent from the first connector 13 can be transmitted through the wireless jacquard 1, wireless jacquard 2, and wireless jacquard 3 (refer to Figure 2 ), ultimately returning to controller 12 via connector 2. When communication or power is normal, the controller receives a corresponding signal from second connector 14, indicating that the entire circuit is functioning properly. If any intermediate node experiences an open circuit or fault, controller 12 may receive an erroneous signal or no signal at all. In this case, controller 12 immediately stops the machine and troubleshoots the problem.

[0076] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 When in use, the third base 111 of one wireless jacquard (wireless jacquard 104) is close to the third base 111 of another wireless jacquard (wireless jacquard 103), and the second power port 115 of one wireless jacquard (wireless jacquard 104) is close to the first power port 114 of another wireless jacquard (wireless jacquard 103), so that the second power port 115 of one wireless jacquard (wireless jacquard 104) and the first power port 114 of another wireless jacquard (wireless jacquard 103) can be detachably installed together in a plug-in manner, thereby quickly achieving electrical connection, which has the advantage of convenient installation, can meet the needs of quick installation, and achieves the effect of killing two birds with one stone.

[0077] Although, in Figure 5 Only four wireless jacquards are drawn as a schematic diagram, but in actual use, it should not be limited to installing four wireless jacquards at the same time. The wireless jacquard is used on a warp knitting machine, and multiple wireless jacquards need to be set in the warp knitting machine. The specific number depends on the machine gauge of the warp knitting machine.

[0078] Reference Figure 6 、 Figure 7 and Figure 8The first power port 114 is a male power port or a female power port, and the second power port is a female power port or a male power port. When the first power port 114 is a male power port, the second power port 115 is a female power port. When the first power port 114 is a female power port, the second power port 115 is a male power port.

[0079] Reference Figure 7 、 Figure 8 and Figure 5 When disassembly is required, the wireless jacquard to be disassembled can be directly removed from the comb mounting portion 101. The power can be cut off at the moment the wireless jacquard is removed. The power-off process is explained below:

[0080] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 The second power port 115 of one wireless jacquard (wireless jacquard 104) and the first power port 114 of another wireless jacquard (wireless jacquard 103) can also be electrically connected by plugging, magnetic attraction or pressing.

[0081] The electrical connection between the male electrical port and the female electrical port is achieved by pressure spring contact, ejector pin contact or round ball contact.

[0082] When the male electrical connection port is a conductive pressure spring, the female electrical connection port is a conductive plug slot, and the electrical connection is achieved by pressure spring contact.

[0083] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 During installation, the third base 111 of one wireless jacquard (wireless jacquard 104) is placed close to the third base 111 of another wireless jacquard (wireless jacquard 103), and the second power port 115 of one wireless jacquard (wireless jacquard 104) is placed close to the first power port 114 of another wireless jacquard (wireless jacquard 103). Because the pressure spring of the male power port is elastic, it can be directly inserted into the plug-in slot of the female power port by plugging, so that the pressure spring directly abuts against the plug-in slot to achieve electrical connection. Then, the third base 111 is locked to the comb mounting portion 101 using the tail clip 122.

[0084] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9When disassembling, loosen the locking screw on the tail clip 122 and directly remove the wireless jacquard (wireless jacquard 104) from the comb mounting portion 101. Because the pressure spring of the male power port is elastic, the pressure spring can be separated from the socket by pulling out during the removal of the wireless jacquard, thereby cutting off the power.

[0085] When the male electrical connection port is a conductive ejector pin, the female electrical connection port is a conductive pin slot, and the ejector pin can be a conductive spring pin. The electrical connection is achieved by ejector pin contact.

[0086] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 During installation, the third base 111 of one wireless jacquard (wireless jacquard 104) is placed close to the third base 111 of another wireless jacquard (wireless jacquard 103), and the second power port 115 of one wireless jacquard (wireless jacquard 104) is placed close to the first power port 114 of another wireless jacquard (wireless jacquard 103). This is because the pin of the male power port can be directly inserted into the pin slot of the female power port by plugging, thereby achieving electrical connection. The third base 111 is then locked to the comb mounting portion 101 using the tail clip 122.

[0087] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 When disassembling, after loosening the locking screw on the tail clip 122, the ejector pin can be pulled out from the needle slot during the process of removing the wireless jacquard, thereby separating the ejector pin from the needle slot and disconnecting the power supply.

[0088] When the male electrical connection port is a conductive round ball, the female electrical connection port is a conductive ball groove, and the electrical connection is achieved through round ball contact.

[0089] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9When installing, the third base 111 of one wireless jacquard (wireless jacquard 104) is close to the third base 111 of another wireless jacquard (wireless jacquard 103), and the second power port 115 of one wireless jacquard (wireless jacquard 104) is close to the first power port 114 of another wireless jacquard (wireless jacquard 103). Because the male power port is a round ball, it can be directly inserted into the ball groove of the female power port in a plug-in manner, so that the round ball directly abuts the ball groove to achieve electrical connection. Then, the third base 111 is locked on the comb mounting part 101 using the tail clip 122.

[0090] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 When disassembling, loosen the locking screw on the tail clip 122 and directly remove the wireless jacquard (wireless jacquard 104) from the comb mounting portion 101. In the process of removing the wireless jacquard, the round ball of the male power port can be pulled out from the ball groove, so that the round ball is separated from the ball groove, thereby cutting off the power.

[0091] When the male electrical connection port is a conductive magnetic connector, the female electrical connection port is a conductive magnetic connection slot, and the electrical connection is achieved through magnetic contact.

[0092] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 During installation, the third base 111 of one wireless jacquard (wireless jacquard 104) is placed close to the third base 111 of another wireless jacquard (wireless jacquard 103), and the second power port 115 of one wireless jacquard (wireless jacquard 104) is placed close to the first power port 114 of another wireless jacquard (wireless jacquard 103). Because the magnetic connector of the male power port is magnetic, it can be directly connected to the magnetic connection slot by magnetic attraction to achieve electrical connection. Then, the third base 111 is locked to the comb mounting portion 101 using the tail clip 122.

[0093] Reference Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9When disassembling, loosen the locking screw on the tail clip 122 and directly remove the wireless jacquard (wireless jacquard 104) from the comb mounting portion 101. In the process of removing the wireless jacquard, the magnetic connector and the magnetic connection slot can be separated by pulling out, thereby cutting off the power.

Regarding the part about the CPU, the CPU is an external controller in the prior art, which is recorded and explained in detail in the reference, and will not be repeated here.

The first assembly holes 202 are adapted to the second assembly holes 201. Screws 200 are passed through the second assembly holes and then locked in the first assembly holes 202, so that the third printed circuit board 113 can be detachably mounted on the rear portion of the third base 111.

[0096] Reference Figure 6 When the stitch length needs to be adjusted before the warp knitting machine is operated, a single designated wireless jacquard can be started as needed. Specifically, an external cable that is separately connected to the external controller is used. The external cable is plugged into the third power port 120 in a pluggable manner to be powered on (input drive power and process signals), thereby driving the single wireless jacquard that needs to be adjusted separately. After the adjustment is completed, the external cable is directly unplugged to end the adjustment, thereby realizing the quick adjustment of the stitch length of the designated single wireless jacquard, which is simple and convenient.

[0097] The needle gauge of a warp knitting machine typically refers to the left-right position of the bar bed relative to the knitting needles. The left-right distance between the guide needles in a row and the knitting needles is controlled by the slider screw on the knitting wheel. Using the needles as a reference, the left-right position of the bar bed is observed and the direction of the screw is adjusted to move the bar bed slightly laterally, aligning it with the center of the needles. Needle gauge adjustment is required before a warp knitting machine can operate normally.

[0098] Reference Figure 6 、 Figure 7 、 Figure 8When the warp knitting machine is debugging the wireless jacquard before use, the third power port 120 is powered on, the first power port 114 is not powered on, and the second power port 115 is not powered on. The third power port 120 is powered on only when the stitch length is debugged, and an external cable is connected to the third power port 120 for power. A wire groove 121 is provided on the tail clip 122, and the external cable can be inserted from the wire groove 121 to achieve electrical connection with the third power interface. When the warp knitting machine is working normally, the third power port 120 is idle, no external cable is installed, and no power is supplied.
