DETAILED DESCRIPTION
[0041] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not used to limit the present application.
[0042] The present embodiment provides a thread cutting and threading method without exposed thread end for the jacquard glove machine, which can make the thread end of the yarn stay inside the knitting area each time the thread cutting and threading operation is performed, realize no obvious residual thread end outside the glove, and at the same time, the thread cutting and threading method can use appropriate thread cutting and threading method in different situations by configuration, make the jacquard glove machine more reasonably perform thread cutting and threading action, and improve the knitting efficiency,
[0043] Specifically, as shown in Figure 1 the method comprises:
[0044] Step S1, the user sets the configuration information of the jacquard glove machine pattern making system;
[0045] Step S2, update each row of pattern row information according to the configuration information;
[0046] Step S3, according to the updated pattern row information of each row, the function bar data parameters of the current pattern row are parsed;
[0047] Step S4, according to the function bar data parameters of the pattern row, the action command corresponding to the to-be-controlled hardware is generated;
[0048] Step S5, the jacquard glove machine controls the corresponding hardware to perform the cutting and laying thread action according to the corresponding action command.
[0049] In one embodiment, step S1 specifically comprises:
[0050] Step S1-1, at least one empty row is added in the pattern view of the jacquard glove machine design system. The empty row has no default yarn nozzle knitting information.
[0051] Step S1-2, a hidden needle is set in the empty row. The hidden needle position mapping specifies the action command of the corresponding numbered hook of the needle selector.
[0052] The hidden needle information means that the hook needle position on the needle plate specified needle position is a hidden needle position. Compared with the hook needle position of the ordinary knitting, the hook needle position of the hidden needle position is lower, and the hooking line is combined with the previous loop. The hooking line of the hidden needle position is usually knitted in the inner layer of the glove, and because the hidden needle hooking line is looped with two lines at the same time, the loop is more compact and not easy to come off. According to the size of the glove machine, there are 52-114 needles in each of the front and back beds. Setting a hidden needle is to knit the inner layer of the glove, and after cutting the yarn, the yarn end will not be pulled. The hidden needle process is often used for knitting the inner layer of the glove during the cutting and laying process.
[0053] Step S1-3, for the pattern row that needs to use the upper cutter to cut and lay the thread, the configuration of the working state of the upper cutter is set.
[0054] The "upper cutter" refers to the cutter device above the needle plate in the upper cutter type glove machine, including the central cutter and the hooks on both sides for hooking and clamping the thread. The horizontal and vertical movements of the cutter are driven by the motor, and the vertical movement can move the cutter to different positions such as cutting thread, eating thread, allowing thread, hooking thread, and laying thread.
[0055] For example, the configuration of the working state of the upper cutter is a process of generating a corresponding cutting and laying action description script according to the configuration information of the current row pattern, empty row, yarn nozzle movement, cutter action, etc.
[0056] The cutting and laying action description script refers to a parameter definition and hardware coordination rule, including setting the head movement action, the hidden needle position of the empty row, the cutter suction action, the horizontal movement action of the upper cutter, and the thread cutting related action of the upper cutter.
[0057] Among them, the description script of the head movement action is "JTYD, x", which means moving the head to position x, where x represents the integer value of the target position of the head. The head position represents the needle position of the center of the head on the needle plate, and the target position value is greater than the current head position, which means the head moves to the left, and vice versa. The head movement script can include: needle selection, yarn nozzle movement, needle plate hooking, needle plate cutting, etc.
[0058] For example, the needle selection action, the description script is "AZ1, 0, 0…", AZ1, 2, 3, 4 controls four different needle selectors on the head respectively, the number 0 represents 1 byte of needle selection content in decimal, if all unselected, it is 0, all selected is 255, each AZ command is followed by 16 bytes of needle selection information at most, corresponding to the needle selection information on the maximum 128 needle positions on the needle plate.
[0059] For example, the yarn nozzle movement knitting action, the description script is "SZ, a, x", indicating that the a number yarn nozzle moves to the x position with the head, wherein the yarn nozzle position represents the integer value of the needle position where the end of the yarn nozzle is located on the needle plate, the coordinate axis direction is consistent with the head coordinate direction, the description script of the forced movement of the yarn nozzle is "$SZ, a, x", which also indicates that the a number yarn nozzle moves to the x position, the difference is that $SZ represents that the yarn nozzle moves alone without following the head.
[0060] For example, the needle plate hook action, the description script is "ZBGD, n", wherein n corresponds to the n number of needle plate hook, the value range is an integer containing 1 to 8.
[0061] For example, the needle plate scissors action, the description script is "ZBJD, 0 or 1", wherein the number 0 represents using the back bed scissors to cut the thread, and 1 represents using the front bed scissors to cut the thread.
[0062] Wherein, the empty row hidden needle position will automatically add the needle selection action of the corresponding needle position in the head movement action, according to the head mechanical structure, the AZ1 needle selection information executed when the head moves right will be changed to the front bed hidden needle needle action in the next head right movement, and the AZ4 needle selection information added when the head moves left will be changed to the back bed hidden needle needle action in the next head right movement.
[0063] Wherein, the description script of the scissors air suction action is "XF, 0 or 1", 0 represents starting the scissors air suction motor, and 1 represents stopping the scissors air suction motor.
[0064] Wherein, the horizontal movement of the upper scissors, the description script is "SJD, bx", indicating that the upper scissors moves to the bx position, wherein bx is an integer value in half needle position units, which is different from the head position and the yarn nozzle position described above.
[0065] Wherein, the description script of the upper scissors thread cutting related action is "J, a", wherein a is 1, indicating that the upper scissors resets, a is 2, indicating that the upper scissors hooks the thread, a is 3, indicating that the upper scissors releases the thread, a is 4, indicating that the upper scissors takes the thread, and a is 5, indicating that the upper scissors lets the thread.
[0066] Specifically, the script is described with ";" as the end of a line, and the description script of the head movement supports multiple operation objects in a line, and the operation objects in the same line are separated by ",".
[0067] Step S1-4, set the number of yarn nozzles and their corresponding positions.
[0068] Step S1-5, set the thread cutting and releasing behavior of the needle plate scissors and the needle plate hook;
[0069] The thread cutting and releasing behavior of the needle plate scissors and the needle plate hook includes a thread cutting action using the needle plate scissors and the needle plate hook, a thread cutting action without using the needle plate scissors and the needle plate hook, a thread releasing action using the needle plate scissors and the needle plate hook, and a thread releasing action without using the needle plate scissors and the needle plate hook. Among the set thread cutting or releasing actions, it is necessary to judge whether to use the needle plate scissors and the needle plate hook to cut or hook the thread according to the actual situation of knitting. The advantage of using the needle plate scissors to cut the thread is that the action to be performed is less and the knitting efficiency is high, but it needs to be limited to the situation where the knitting area is close to the needle plate scissors, which is suitable for thread cutting in the palm part, while thread cutting in the finger part needs to be completed using the upper scissors.
[0070] The needle plate scissors and hook are the scissors and hook components at the rightmost side of the needle plate, and there are one scissors and four hooks in front and back beds. The needle plate scissors are a scissors device close to the rightmost hook of the needle plate, which can cut the hooked yarn when the needle is withdrawn, or can clamp the yarn. The needle plate hook is a thread clamping device to the right of the needle plate scissors, which can clamp the yarn when it is withdrawn, or can cut the yarn.
[0071] Specifically, a simple schematic diagram of the position of each component of the glove machine is as follows: Figure 2 As shown in the figure, 1 represents the position of the head, which can move left and right and perform needle selection and other related operations; 2 represents the position of the back bed, where the rectangular bar represents the needle selection of the needle plate; 3 represents the position of the needle plate scissors of the back bed; 4 represents the needle plate hook of the back bed, and the numbers are sequentially 2, 4, 6, and 8 from left to right; 5 represents the position of the hook to the left of the upper scissors; 6 represents the thread cutting position of the upper scissors; 7 represents the hook to the right of the upper scissors; 8 represents the position of the yarn nozzle, which actually has 8 yarn nozzles; 9 represents the position of the needle plate hook of the front bed, and the numbers are sequentially 1, 3, 5, and 7 from left to right; 10 represents the position of the needle plate scissors of the front bed; 11 represents the position of the front bed; and the needle plate scissors in the figure are the coordinate 0 point position, which increases to the left and decreases to the right;
[0072] "thread releasing", refers to the yarn is clamped by the needle plate hook, not knitted on the needle plate hook, that is, there is no connection between the yarn nozzle and the hook, when starting to knit, the clamped thread at the hook needs to be released and transferred to the upper scissors hook. Setting the thread releasing action, the thread releasing nozzle and the needle plate hook need to be set, the function is to cut the yarn between the thread releasing nozzle and the needle plate hook, and place the yarn between the needle plate hook and the thread cutting nozzle in the knitting area, waiting for the next knitting action.
[0073] "thread cutting", refers to the yarn is knitted on the needle plate, and the subsequent yarn is not used, the connection between the needle plate and the nozzle needs to be cut, and the cut nozzle thread clamp is transferred from the upper scissors hook to the needle plate hook clamp. Setting the thread cutting action, the thread cutting nozzle and the needle plate hook need to be set, the function is to cut the yarn between the thread cutting nozzle and the needle plate hook, and transfer the yarn between the needle plate hook and the thread cutting nozzle on the right side of the knitting area.
[0074] For example, the "thread releasing action of not using needle plate scissors and needle plate hook", the thread releasing nozzle number is set to 6, and the needle plate hook number is set to 4; The specific is as follows:
[0075] Step (S011): thread releasing starts, the needle plate scissors air suction motor is started. For example, the needle plate scissors air suction motor is located below the needle plate scissors, which is used to process the cut thread during knitting.
[0076] Step (S012): the upper scissors move horizontally to the position corresponding to the needle plate hook;
[0077] Step (S013): hooking action is performed;
[0078] S0131: move the thread releasing nozzle to the left side of the upper scissors A position (for example, 2.5 cm) outside the hook;
[0079] S0132: the upper scissors are lowered to the hooking position;
[0080] S0133: the thread releasing nozzle is moved from the left side of the upper scissors to the right side B position (for example, 3.5 cm) outside the hook, so that the hooks on both sides of the upper scissors hook the yarn, and the yarn is horizontally across the upper scissors and the hooks on both sides;
[0081] S0134: the upper scissors are reset upward to cut the horizontal yarn, and the right hook clamps the yarn;
[0082] S0135: the hooking action is completed;
[0083] Specifically, in the hooking action of the embodiment, the yarn feeding nozzle must be moved to the left side of the upper scissors before the upper scissors descend to the hooking position, otherwise, the yarn feeding nozzle and the upper scissors may collide. According to the steps in S0133, after the yarn feeding nozzle is moved from left to right to the right side of the upper scissors, the yarn carried by the yarn feeding nozzle just falls on the hooks on both sides of the upper scissors. When the upper scissors are reset upward to cut the yarn, the yarn between the upper scissors and the needle plate hook is pulled off under the action of tension. At this time, the needle plate hook clamps the residual thread end, and the hook on the left side of the upper scissors also clamps the residual thread end.
[0084] Step (S014): thread end processing;
[0085] S0141: the upper scissors descend to the thread releasing position, horizontally move right to the right side of the needle plate hook C position (for example, 10 cm), at this time, the cut thread end clamped by the hook on the left side of the upper scissors is pulled apart, and the right hook still clamps the thread end between the yarn nozzle.
[0086] In the embodiment, the upper scissors move to the rightmost position, in order to avoid collision with the upper scissors when the head moves.
[0087] S0142: the head moves left, controls the needle plate hook to release the cut yarn end, and the scissors suction cleans the released thread end;
[0088] S0143: after the head leaves the needle plate hook, the upper scissors move back to above the needle plate hook and reset, and the needle plate scissors suction motor is turned off;
[0089] Step (S015): the upper scissors and the yarn feeding nozzle are both moved to the left side of the hidden needle position and are both located in the knitting area, the yarn feeding nozzle is at the right side of the upper scissors D position (for example, 7 cm), and the upper scissors descend to the thread taking position;
[0090] Step (S016): the head moves right, the yarn feeding nozzle and the needle plate hook form a thread taking connection, the yarn feeding nozzle moves to the right side of the knitting area E position (for example, 6.5 cm), the upper scissors release the yarn, and the remaining thread end is located in the knitting area. The final product glove has no exposed thread end;
[0091] Step (S017): the feeding is completed.
[0092] The different positions are represented by letters ABCDE in the above, and the same letters are used to represent the positions in the following. The specific values can be set in the thread cutting and feeding function bar according to the actual situation.
[0093] For example, the "yarn feeding action using the needle plate scissors and the needle plate hook" is provided, in which the number of the yarn feeding nozzle is 3, and the number of the needle plate hook is 7. The specific steps are as follows:
[0094] Step (S021): start feeding, turn on the needle plate scissors suction motor;
[0095] Step (S022): The head moves left, and the yarn feeding nozzle follows the movement of the head to the set left side A position (for example, 5 cm) of the dark needle, and the needle plate scissors cut the yarn between the yarn feeding nozzle and the needle plate hook and clamp the yarn;
[0096] Step (S023): The head moves right, and the yarn feeding nozzle and the needle plate hook form a thread connection;
[0097] Step (S024): The yarn feeding nozzle moves to the left side B position (for example, 1 cm) of the needle plate scissors and is located in the knitting area;
[0098] Step (S025): The needle plate scissors release the clamped yarn between the needle plate hook, and due to the elasticity of the yarn and the close distance (about 1-3 needle positions) between the dark needle position and the needle plate scissors, the thread end can be fully retracted into the knitting area;
[0099] Step (S026): The needle plate hook releases the thread end, the scissors suction cleans the released thread end, and the needle plate scissors suction motor is turned off;
[0100] Step (S027): The feeding of the yarn is completed.
[0101] For example, the "no cutting action using the needle plate scissors and the needle plate hook", wherein the set number of the cutting yarn nozzle is 5, and the number of the needle plate hook is 2; the details are as follows:
[0102] Step (S031): Start cutting, turn on the needle plate scissors suction motor;
[0103] Step (S032): Perform the hooking action;
[0104] S0321: Move the cutting yarn nozzle to the left side A position (for example, 3 cm) outside the hook of the upper scissors;
[0105] S0322: The upper scissors descend to the hooking position;
[0106] S0323: Move the cutting yarn nozzle from the left side of the upper scissors to the right side B position (for example, 1.5 cm) outside the hook, so that the hooks on both sides of the upper scissors hook the yarn, and the yarn is horizontally across the upper scissors and the hooks on both sides;
[0107] S0324: The upper scissors are reset upward to cut the horizontal yarn, and the right hook clamps the yarn;
[0108] S0325: Complete the hooking action;
[0109] Step (S033): The upper scissors move to the set position above the needle plate hook and descend to the thread connection position, the head moves left, the needle plate hook hooks the yarn, the upper scissors feed the yarn, and the thread end is processed;
[0110] Step (S034): Turn off the needle plate scissors suction motor;
[0111] Step (S035): Finish cutting the thread.
[0112] For example, the "thread cutting action using needle plate scissors and needle plate hook", in which the number of thread cutting nozzles is set to 6, and the number of needle plate hooks is set to 4; the specific process is as follows:
[0113] Step (S041): Start cutting the thread, turn on the needle plate scissors suction motor;
[0114] Step (S042): Perform the hooking action;
[0115] S0421: Move the thread cutting nozzle to the outside of the left hook of the upper scissors at position A (e.g. 3.5 cm);
[0116] S0422: Lower the upper scissors to the hooking position;
[0117] S0423: Move the thread cutting nozzle from the left side of the upper scissors to the right side of the hook at position B (e.g. 4 cm), so that the hooks on both sides of the upper scissors hook the thread, and the thread is horizontally across the upper scissors and the hooks on both sides;
[0118] S0424: The upper scissors are reset upwards to cut the horizontal thread, and the right hook is used to clamp the thread;
[0119] S0425: Complete the hooking action;
[0120] During the operation, when the upper scissors move the thread end into the inside of the knitting area, the thread end refers to the thread end between the left hook and the needle plate hook.
[0121] After the current step is completed, the upper scissors are located directly above the knitting area, the thread cutting nozzle is located outside the knitting area, and the right side of the needle plate hook. Therefore, the next step is to move the thread cutting nozzle back to the right side of the upper scissors to facilitate the needle plate hook to hook the thread.
[0122] Step (S043): Move the upper scissors to the left by C positions (e.g. coordinate 5 cm), and pull the thread end clamped by the left hook into the inside of the knitting area. The thread cutting nozzle follows the thread end to move to the right side of the upper scissors at position D (e.g. 3 cm);
[0123] Step (S044): Lower the upper scissors to the thread taking position, and move the thread cutting nozzle to the right of the set needle plate hook. During the right movement, the needle plate scissors clamp the thread, and the needle plate hook hooks the thread of the thread cutting nozzle;
[0124] The thread between the hook on the right side of the upper scissors and the needle plate scissors is removed by the subsequent step of loosening the needle plate scissors and the upper scissors.
[0125] Step (S045): The needle plate hook and the needle plate scissors are used in sequence to cut the yarn between them, and at this time the yarn is located between the thread cutting nozzle and the needle plate hook. The upper scissors are used to remove the thread.
[0126] Step (S046): The needle plate scissors air suction motor is turned off.
[0127] Step (S047): The thread cutting is completed.
[0128] In one embodiment, in step S2, the pattern row information includes front bed front and back pattern data, back bed front and back pattern data, functional bar data, and upper scissors horizontal position data.
[0129] Further, the front bed front and back correspond to the front and back of the right-hand glove respectively, and the back bed front and back correspond to the front and back of the left-hand glove respectively.
