The present invention relates to an automatic Intasia flat knitting machine, and more particularly, to an automatic Intasha flat knitting machine operated by a computer method.

In the conventional manual intasha knitting method, the number of yarns required by the design to be knitted in advance is passed through the thread guides installed at the rear of the flat knitting machine, arranged, and then the yarns which are artificially selected and replaced are designed to weave together. The number of loops was applied to the needle nose, repeated one step at a time, and then the cam carriage was moved to form a loop and work step by step.

The artificial thread change and cam carriage movement as described above are not only low productivity, but also unstable knitting due to uneven tension of the thread according to skill and fatigue with the operator. Is impossible, and in the case of knitting, the productivity is extremely low, the production cost is very high, and the manpower is consumed.

In addition, when working continuously for a long time as described above was not only to reduce productivity, but also to increase the work error was to damage the value as a product.

The present invention has been solved by automatically integrating by computer control method in order to solve various problems such as thread replacement, cam carriage movement, tension adjustment, error prevention, and quality improvement.

In addition, all defects or operation errors are automatically detected before and after knitting, and defects can be eliminated in advance to improve quality, and more than 100 types of yarns can be used to obtain Intasha products with complex and diverse designs. It would be.

Another feature is that all the drives become variable speed and control the slow start, constant speed operation and deceleration stop instantaneously so that the machine is stable because there is no difficulty in the machine, and the reciprocating linear motion is carried out by the LM guide to reduce the wear and vibration of the machine. It is possible to operate at high speed because it is reduced, and precise position control can be performed by using timing belt.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of the present invention, the automatic interlock flat knitting machine, FIG. 2 is a perspective view of the feeder housing, FIG. 3 is a detailed view of the feeder housing, FIG. 4 is a perspective view of the rotary part, and FIG. (Exchangins) and the operation of the rotary diagram, Figure 6 is a diagram illustrating the operation of the feeder insertion and rack bar (Rack Bar) This configuration is to be operated by the electrical schematic of Figure 7, such electrical schematic is It is designed to operate according to the floor charts of FIGS. 8 and 9, and those who have basic knowledge about computers are known by the floor charts, and thus, the description thereof will be omitted for simplicity.

FIG. 11 is inputted according to the drawing of an example for inputting to a computer in the case of the graphic design illustrated in FIG. 10.

First, when the graphic design of FIG. 10 is input to the computer, as shown in FIG. 11, P.DATA is position data, which means Y-axis NO, which means immersion data.

In addition, C.L DATA means Color DATA. In FIG. 10, feeder NO is represented by A color (horizontal line), CN 1 (control 1) DATA,

CODE TWIST CCW to the carriage right

CODE 1 is carriage leftward TWIST CW

CODE 2 is the carriage departure time in the complex. Right

CODE 3 is the departure time of the carriage. Left

CODE 4 indicates NEEDLE DROP for 16R. left side

CODE 5 indicates NEEDLE DROP for 16R. right

Means,

CN ₂ (Control 2) DATA is Cam carriage departure time.

The cam carriage speed, in the graphic design of FIG. 10, needles 1 to 5 and needles No. 41 to 45 of Rounds 1 to 15 are not actually knitted, but are free spaces for the rotary housing to move. Of course, the width is only for immersion to provide such a width can be arbitrarily organized according to work.

Therefore, in the graphic design of FIG. 10, A is the color portion, such as position data (P.Data), extent color data (CL Data), and control-1 data (CN-1) as shown in FIG. Data and CN-2 data can be created and input into the Data input ROM, and inserted into the text tool of a control box (not shown).

Next, the knitting yarn is passed through the seal guider 13 and the feeder 2 as in the code No of the CL-Data (hole order of the feeder housing) to apply a load.

When the work is completed, the work can be started. In the case of the initial light (initialization) as shown in the display support plate of FIG. 12, the sensors S-1, S-2, and S-3 are fed to the feeder carriage 1 ) Set the expedition of the feeder housing (3) and rotary (1) and operate the start switch (SW ₁ ), all the operations are displayed by the data control PC control data, the indicator control driver starts the display, As shown in the figure, the rear cylinder C-1 and the front cylinder C-2 hit the center of the feeder 2 at the direction of the cylinder driver, thereby creating a new knitting and finishing work. The knitting yarn is inserted into the rotary housing 17. At this time, if cylinder sensor (S-4) operates to transmit yes signal, cylinders (C-1, C-2) are off at the same time and microprocessor (CPU) operates the stepping motor (M-3) driver to pulse ( The motor M-3 is driven in accordance with the Pulse) signal to rotate the rotary 16 by 180 degrees by the ratio of the pinion gear 19. As shown in FIG.

By rotating the rotary 16 in such a manner as shown in FIG. 4, a knitted cross is exchanged as shown in FIG. The lower chad of FIG. 9 shows an orthogonal method, and when the thread is inserted into the feeder carriage by hitting (C-1), the stepping motor N-1 is driven and the empty feeder next to the new seal feeder housing. When the housing is stopped, the feeder of the carriage is inserted into the feeder housing by hitting (C-2).

At this time, the stepping motor M-2 is addressed back by one feeder position and a new thread is inserted into the feeder carriage 1 by the impact of the cylinder C-1, and a cross is formed. (Stroke) The length is longer and the time required due to the operation in 3 steps can be made by rotary method, and it is possible to shorten the time required by one step by about 1/3 of the conventional time in order to cross easily and continuously. You can improve productivity by shortening it by more than a minute.

In particular, instead of taking two holes (Hole) of the feeder housing (3) in the direct exchange method by inserting the terminated knitting feeder into the empty hole of the new knitting yarn, it is possible to use twice the knitting yarn than the orthogonal method, so that the complex and various designs can be used. There is a characteristic to organize.

In addition, in the case of a simple design, the same yarn can be divided and divided into 4-6 pieces per round, reducing the length of the rest yarn formed on the back side of the product, facilitating the finishing work, and controlling data (CN-1). code The rotary direction is CCW when the knitting direction is from left to right, and the twisting phenomenon occurs between the knitting yarns shown in FIG. 4, and when the control data code (Code) -1 (right → left is knitting direction), the rotary direction is rotated. ) The rotation direction is CW and Code- Twist exchanged crosswords are cross code Twist phenomenon that occurs in the system automatically recovers.

In this way, when the rotary 16 is rotated 180 ° and the (C-1, C-2) return sensor (S-5) is activated and the signal is yes, the cylinder driver operates the cylinder (C-3) in FIG. As shown, when the rack geared bar (18) built into the rotary (16) is hit, the pinion gear (19) proceeds in the opposite direction to each other and the new knitting yarn is terminated in the feeder carriage (1). The yarn is inserted into the feeder housing 3.

However, when the conventional direct replacement method is selected, a stroke takes 50m / m or more, so a large torque is required when hitting, which causes excessive impact on the feeder carriage 1 and the feeder housing 3, resulting in a long stroke. The positional deviation due to hitting position error is severe during progression, so the feeder carriage wear is severe, and in the case of the conventional spring type housing, the positional deformation occurs, and if such accumulation is repeatedly accumulated, the spring breakage or the feeder damage occurs and the feeder ( 2) It takes a long time due to the spring exchange and the machine takes a long time.

However, according to the embodiment of the present invention, since the stroke can be set to 15 m / m or less by adopting the rotary method, the feeder 2 can be moved even with a shorter time and less torque, and there is no positional deviation and the impact is minimized so that the feeder There is almost no breakage or deformation of the feeder housing.

As shown in FIG. 3, the unevenness is applied to the feeder 2 to insert the six-sided contact between the feeder carriage 1 and the feeder housing 3 so that the external tension increases when the feeder 2 is moved or when the feeder housing 3 is operated. Or it can maintain the horizontal vertical of the feeder during the impact vibration to prevent the needle breakage, knitting yarn hole deviation, feeder housing departure due to poor feeder gripping (把持).

In FIG. 2, the feeder is made of stainless steel, and the housing and the carriage are made of polyamide-based resin to improve spring effect and grip force by using elasticity, abrasion resistance, and elasticity. In the form of the neck 22, the gripping force can be increased.

As described above, in the case of the leaf spring, the gripping length and guide distance are shortened to 6 m / m or less compared to 12 m / m, so that the impact of the feeder 2, the feeder carriage 1 and the feeder housing 3 is reduced. It can reduce the travel distance and travel time and save air pressure consumption.

When the feeder housing 3 has been replaced with the feeder carriage 1, the feeder presence sensor S-6 is activated so that the yes signal is rectified in the buffer as shown in the flow chart of FIG. The position control PC reads the data and sends it to the speed control IC, and sends pulse, rotation direction conversion, and step angle change signals to the motor driver by the exposition position data programmed in the ROM. Drive the stepping motor (M-1) by using Code No-1 of CN 1-Data or By CW and CCW, the number of control pulses of the pattern control unit is determined, and the acceleration, constant speed, and deceleration instructions are given as the frequency changes, and the position control is performed according to the supply pulse.

On the other hand, the feeder carriage 1 reciprocates by the LM shaft 7 guide with the timing belt 9 driver system according to the driving of the stepping motor M-1, and thus the timing belt as compared with the rack gear or the roller chain system. The driver system has low interference between the teeth of the movement belt and the teeth of the pulley, and minimizes slippage, speed fluctuations, backlash, etc., so it is excellent in positioning and there is no need for oil supply, so there is no risk of oil contamination and maintenance. It can reduce the cost and reduce the weight.

That is, the embodiment of the present invention is not a friction drive, such as V-belt, so no extra tension is required, so the load is good due to less celebration, the wear is long, the life is long, and the belt speed is up to m / sec. It is possible to produce high-speed round and the timing belt vibration is very quiet under normal motion conditions, so it has no noise.

In addition, since the LM shaft 7 has extremely small starting, disengaging, resistance, and frictional motion due to the bearing rotation contact, it requires a small torque when starting the motor, so that it can be speeded up to a small power source, and the friction coefficient according to the working load heavy pressure hardly changes. As a result, there is little frictional loss even under heavy loads, and a reliable guide function is provided for a long time. (With both seals, lubricant leakage can be suppressed and it can be used even in a non-lubricated state). In addition, the flexible linear movement is free from vibration and noise, and it is easy to exchange because it is fully compatible.

Since the knit product has dimensions in inches, the foretending M / C 11 arranged the needles 12 in inches. The error per unit length in the position conversion of these metrics is that the stepping motor is proportional to the rotation angle input pulse, so the position control is surely selected by selecting the stepping angle (0.36 °), which is illustrated in FIGS. 10 and 11. The pattern is described in more detail by way of example.

In other words, for example, the 11th stage (Round), the data input to the ROM and the central processing element reads the data (P-data) and the data (P-data) is øø ＂stepping motor (M) -1) Since it is not driven, the feeder carriage 1 is in the submerged No ø position and the data (C-data) ＂3＂, so the stepping motor M-2 is driven and the feeder housing 3 moves so that the feeder No, the 3 position coincides with the feeder carriage 1 position.

At this time, when the cylinders C-1 and C-2 hit the center of the feeder 2 and the feeder 2 is inserted into the rotary housing 17, the stepping motor M-3 is driven to rotate the rotary 180 °. Rotate When the rotation is completed, the cylinder (C-3) is operated, hitting the rack gear bar (18) built in the rotary feeder (2) is moved to the outside of the needle to end one step operation.

When the next input DATA is read again by the central processing element (P-data 16, C-data 23) and the stepping motor M-1 is driven, the feeder carriage 1 is flooded. The stepping motor M-2 is driven at the 16 position to move the feeder housing 3 so that the feeder No. 23 coincides with the feeder carriage 1.

By repeating the operation as described above it is possible to control the exact position.

When the stepping moving (M-2) described above is driven, the rollers 4 on both sides and the LM guide 5 fastened to the timing belt 9-2 fixed by the feeder timing belt pulley are engaged in the reciprocating linear motion. By this, the positioner of the feeder housing 3 can be controlled correctly.

The L.M guide 5 was installed on the left and right side to guide the straight movement of the feeder housing 3 during the reciprocation of the timing belt 9 fastened to the feeder housing 3. Since the friction guide surface of the LM guide (5) has little fluctuation of friction coefficient due to high speed, smooth operation guide can be performed without slippage caused by sliding guide, so there is little wear, no noise, moment load and starting load by driving friction of ball bearing. It has high rigidity against and does not affect the cloud due to the dispersion of support points during impact load, and has enough controllability within the error range of the installation surface so that the position control with the smallest error is possible, miniaturizing the power source and the life of the motor. You can lengthen it.

As described above, when feeder extinguishing, feeder movement and simultaneous feeder housing movement by P-Data and C-Data are completed, P-Data modulation is determined, and if No, a step is performed on the signal liquid crystal display by the address recorder. And the above-described series of operations are repeated as in the lower chart of FIG.

If P-Data change is judged and yes, Code-1 is CW and Code-ø is CCW direction by the rotation direction signal input after reading P-Data Code No. The direction is indicated and the programmed IC adjusts the speed of VR ₁ , VR ₂ , VR ₃ by the dial of the speed setter built in by the control data (C-1, C-2) at 1500 r at r, p, m. By setting up to p, m and calibrating the dial of the external speed controller, the speed setting resistance can be set from 0 to 204 ohm (Ω), so that it can control up to 1500r, p, m.

In addition, the cam carriage 10 fastened to the V-belt was configured to complete the knitting of the moving hook.

The acceleration and low-speed movement of the cam carriage 10 reduced the instantaneous coefficient of friction between the knitting yarn and the metal between the knitting points in the thread cage due to the sudden increase in the knitting tension of the knitting yarn, thereby preventing the thread trimming and the hook detachment of the knitting yarn.

In addition, due to the acceleration of sudden death, it is possible to reduce the declination caused by the roving back phenomenon during sudden stop and the knitting recovery after knitting, and to prevent natural deficiency such as tight selvage. It can reduce needle and machine damage and reduce noise.

The knitting knot supplied from the seal package when the feeder carriage and the cam carriage move is rectified by the sensor circuit (S-10) shown in Fig. 1 to stop the machine automatically by the sensing circuit. The knot display light emitting diode (LED) is operated by the signal of the driver, so that the knot defect caused by the knot is prevented in advance.

The sensor S-8 of FIG. 1 supplies a positive power to the upper part of the seal guide 13 and a negative power to the tension spring 14, and to the tension spring 14 due to trimming and empty seal package. As the tension is consumed, it contacts with the upper (+) power source and becomes the ON-OFF type switch, the machine is stopped, and the trimming light emitting diode (LED) of the indicator is turned on, and the sensor (S-9) is knotted or external tension Sensed that the exaggerated tension caused by the machine was stopped and displayed by the light emitting diode (LED).

In addition, the capacitive proxy sensor S-12 attached to the upper and left shaft portions of the cam carriage 10 during the movement of the cam carriage 10 indicates that there is no knitting on the hook, so as to pre-arrange the knitting defect. The moving cam carriage is stopped by the detection signal of the portable proximity sensor (S-11) set according to the width of the knitted fabric, and the step and round address of the position and color control data are increased. Stops and rounds are crossed and a signal is sent to the 7-segment indicator to repeat the series of operations described above to automatically continue integrating Instasia.

In the case where the knitting is small, the knitting time can be shortened by fixing the moving width of the cam carriage by the sensor S-11.

On the other hand, if the satin (Ground knitting) or the number of steps (negative change) / Round is very small, divide the 4-6 points in front of the feeder carriage and install the proximity sensor (S-6) to the CN ₂ -Data input. Accordingly, the start time of the cam carriage 10 can be determined while the feeder carriage 1 is moved, and the knitting time can be shortened by driving the motor M-4, and the take-up roller according to the detection signal of the sensor S-16. The motor (M-5) of (16) is operated to maintain the winding tension of a certain load during knitting, and by attaching a weight in a conventional manual knitting or the like to reduce the tension due to the load fluctuation according to the knitting length in the method by the physical needle It is possible to prevent defects such as knitting irregularities and loose selves in advance.

Sensor (S-7) supplied with (+) power on the back of the cam carriage (--7) ) The machine is stopped by the electrical contacts of) and the LED is turned on.All error signals sent from the above sensors are rectified in the buffer and the status of the error is displayed through the indicator driver. To stop and control the circuit of the motor by sending a stop command signal to the input / output circuit of the CPU Main Board with the extension and position control software. By converting the weather control signal, it is operated again from the desired step.

All of the above operations can be repeatedly repeated as shown in the flow chart of FIG. 8 to braid the fabric, and can be repeated braided in the same manner as the first braided, or can be used indefinitely depending on the program to be changed to a different braid every time. have.

Since this is done by the computer operation method, there is a feature that does not require special technical skills.

In the above-described embodiment, the data creation method may be automatically generated by the pen input unit by inputting to a computer, and the ROM table may be externally or embedded in the microcomputer. The exchange method is a cylinder (C ₁ ~ C ₃ ), but it is clear that not only air or oil, but also a magnetic solenoid or a motor driven crank system is within the scope of the present invention.

As described above, since the present invention is intended to be operated by a computer, the present invention is an industrially useful invention that can obtain excellent features and effects while solving various conventional drawbacks described at the outset.
