Description

Detailed Description of the Invention "Industrial Application Field" The present invention provides a method for inspecting the operation of an electronic knitting machine that stores a pattern to be knitted in a memory and selects needles while displaying it on a display device. Regarding.

"Prior Art" In this type of electronic knitting machine, especially in a hand knitting machine, various sensors are used to control needle selection operations etc. as the carriage slides. This greatly affects overall control.

Conventionally, in order to inspect the operating state of each sensor, the operating timing between sensors, etc., an off-the-shelf oscilloscope was used to inspect each sensor individually.

``Problems to be Solved by the Invention'' For this reason, only a skilled engineer could perform the inspection, and it was extremely inconvenient to provide so-called after-sales service.

An object of the present invention is to enable the electronic knitting machine itself to operate various sensors easily and at the same time, so-called "senfuchinic".

"Means for Solving the Problem" In order to achieve this objective, the present invention stores the outputs of a plurality of sensors that control needle selection operations etc. as the carriage slides, and stores the stored data in a memory. The pattern is input to a display device that displays the pattern, and is simultaneously displayed on the display surface according to the output timing between the sensors.

``Operation'' When the carriage slides, the operating status of various sensors can be checked.
The patterns are displayed simultaneously on the same display device that displays the pattern in a manner that corresponds to the output timing between the sensors.

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

FIG. 1 is a conceptual configuration diagram of the entire electronic knitting machine (hand knitting machine), FIG. 2 is a sectional view thereof, and FIG. 3 is a side view. In Fig. 2.3, a horizontally long liquid crystal display device 4 is located at the center of the rear part (rear part of the needle bed) 3 of the needle bed 2 of the knitting machine main body l, and is rotatable (up and down) by an angle adjustment mechanism 5. It is pivoted to. The display device 4 is in a lying position where it lies down almost horizontally on the needle bed 2 as shown by the solid line in FIG. It can be rotated between the standing position and can be held standing at any angle within this rotation range, and in the standing state, the front liquid crystal display panel (LCD) 4a
(Figure 1) facing diagonally upward. Display panel 4
A touch panel 4b is superimposed on the surface of a, and the display on the display panel 4a can be seen through the touch panel 4b. On the left and right side surfaces of the display device 4, IC card insertion ports 4c are provided into which an IC card (RAM card), which is an external memory, can be removably inserted.

After the display device 4 is laid down, the top surface of the knitting machine main body 1 is covered with a separate cover 6, and the display device 4 is placed in the space 7 formed between the cover 6 and the top surface of the needle bed 2. be accommodated. The carriage 8 that slides on the needle bed 2 is also housed in this space 7 with its handle 9 tilted down, as is known in the art. When the carriage 8 is housed, the sliding movement of the carriage 8 is restricted, for example, at the left end of the needle bed 2 (see FIG. 3).

In this electronic knitting machine, after adjusting the display device 4 to an arbitrary angle, inputting commands to the CPU from the touch panel 4b to select various modes as described later, and creating the pattern to be knitted using the touch panel 4b. At the same time, it is displayed on the display panel 4a, and after determining the type of abscess and storing it in the memory on the knitting machine main body 1 side, the stored contents are read out in accordance with the sliding timing of the carriage 8, and the contents are read out in accordance with the sliding timing of the carriage 8. The hands are moved by the well-known left and right electromagnetic hand movement devices provided. The needle selection is performed by the left needle selection device when the carriage 8 slides to the left, and by the right needle selection device when the carriage 8 slides to the right. In FIG. 1, only the needle selection solenoids 10a and 10b of the left and right needle selection devices are shown. An elongated endless connecting belt 1 installed in the rear part 3 of the needle bed.
1 and the carriage 8 are connected by left and right coupling mechanisms 12a and 12b mounted on the carriage 8, and as the carriage 8 slides, the coupling belt 11 is circulated, and a carriage timing pulse is generated in the rear part 3 of the needle bed. A timing pulse corresponding to the sliding movement of the carriage 8 is generated by the generator 13 . In addition, there are current collecting bags on the left and right needle selection solenoids 10a and 10b on the carriage 8 from the l side of the knitting machine main body! 14, and then these connecting mechanisms 12a, 1
2b, the carriage timing pulse generator 13 and current collector 14 will be explained.

Note that various operations such as pattern creation, storage, readout, and hand movement are all controlled by the CPU, as will be described later.

As shown in FIG. 9, the connecting belt 11 has circular burrows 15 and oval connecting holes 16 formed alternately at regular intervals over its entire length. Sprocket wheels 1 at both left and right ends shown in the diagram
A hook is passed between 7a and 17b, and the belt guide 1 is fixed to the front surface of the rear end upright wall 2a (Fig. 2) of the needle bed 2.
It circulates while sliding along 8.

On the other hand, as shown in FIG.
A connector 20, which is an inverted plate piece, is fixed to the front end portion of the connector which can swing back and forth. The connector 20 is a connecting bell) 1
1. A convex portion 20 that can fit into one connection hole 16 of 1.
It has a. Note that this figure shows a state in which the carriage 8 is removed from the needle bed 2.

As shown in FIG. 4, when the carriage 8 is set on the needle bed 2 while moving from the left or right end to the right or left, the convex portion 20 of the connector 20 is
a fits into one connecting hole 16 of the connecting belt 11, and is held in this state by the spring force of the leaf spring 19. Therefore, the connecting belt 11 is connected to the carriage 8, and the carriage 8
When the connecting belt 11 is slid, the connecting belt 11 circulates.

Next, to explain the current collector 14, there is a
A horizontally elongated insulating bar 21 made of synthetic resin and collector introduction guides 22 made of synthetic resin are horizontally fixed to both left and right ends of the insulating bar 21 . A collector guide groove 23 is provided on the entire front surface of the insulating bar 21, and a collector guide groove 2 is provided on the collector introduction guide 22.
An introduction guide groove 24 continuous to the insulating bar 2 is formed.
A conductive plate cable 25 is embedded in the current collector guide groove 23 of the first embodiment.

On the other hand, at the left and right ends of the rear edge of the carriage 8, a fifth
~ As shown in Figure 7, each insulated guide stand 2 made of synthetic resin
6 is attached to the recess 2 on the upper surface of the insulation guide stand 26.
A plate-shaped conductive current collector 27 is disposed within 6a so as to be slidable back and forth, and a plate-shaped retraction actuation member 28 is fitted slightly above the current collector 27 so as to be slidable back and forth. There is. The collector 27 has a slightly vertically elongated small roller 29 pivotally supported on its upper surface, and a spring receiver has a protrusion 30 cut and raised on its lower surface. The collector 27 has a spring holder on the protrusion 3.
0 into the guide groove 31 of the insulating guide stand 26 and the small roller 29 into the guide slot 32 of the evacuation actuating member 28, the roller slides back and forth along the guide groove 31 and the guide slot 32. .

Further, the current collector 27 is biased rearward by a compression spring 33 disposed within the guide groove 31.

When the carriage 8 is moved and set on the needle bed 2 from its left or right end to the right or left as described above, the collector 27 is moved to the collector introduction guide 22 at the left or right end.
It enters the collector guide groove 23 of the insulating bar 21 while being guided by the introduction guide groove 24 of the insulating bar 21, and is pressed into contact with the plate cable 25 as shown in FIG. 6.7.

When the carriage 8 is slid from side to side, the current collector 27 is biased backward by the compression spring 33, so it comes into sliding contact with the temporary cable 25iP, and no matter where the carriage 8 is on the needle bed 2, the needle bed 2 is knitted. Power is supplied from the machine body 1 side to the left and right needle selection solenoids 10a and 10b on the carriage 8 side as described later.

By the way, when simply plain knitting, it is not necessary to supply power to the left and right needle selection solenoids 10a and 10b.

Therefore, when a known knitting course switching member (not shown) (switching lever or switching dial) provided in the center of the upper surface of the sheep is set to plain knitting, the carriage 8 is equipped with a switching cam that rotates together with this knitting course switching member. Left and right connecting levers 36 that rotate in conjunction with the connecting lever 34, and left and right retracting levers 37 that are further rotated by the connecting lever 36 are attached.

In other words, if the knitting course switching member is set to flat,
In FIG. 5, the switching cam 34 is rotated, and the left and right connecting levers 35 are rotated as shown by chain lines.

As a result of this rotation, the left and right retraction levers 36 are rotated to the positions shown by chain lines in the figure, and push the small roller 29 of the current collector 27 forward as shown in FIG. Therefore, the current collector 27 is slid forward and away from the plate cable 25. Furthermore, as the small roller 29 moves forward, it engages with the front end of the guide elongated hole 32 of the evacuation actuating member 28, causing the evacuation actuating member 28 to slide forward.

This forward movement of the retraction actuating member 28 causes the leaf spring 19 to
The free end of the connector 20 is pushed forward, and the connector 20 is connected to the connecting belt 1.
1 through the connecting hole 16.

Therefore, in this state, there is no resistance due to the sliding contact of the current collector 27 and no circulation resistance force of the connecting belt 11, so that the carriage 8 can be easily slidably operated.

Next, the carriage timing pulse generator 13 will be explained with reference to FIGS. 1O to 13.

The sprocket wheel 17b on the right side, on which the connecting belt 11 is hung, is horizontally rotatably supported by a wheel shaft 38 vertically fixed on the base plate 37, and when the connecting belt 11 is circulated by sliding of the carriage 8. , carriage 8
The wheel rotates clockwise or counterclockwise around the wheel axis 38 depending on the direction of travel. This wheel shaft 38 also includes
A disk-shaped rotary encoder 39 is supported by a disk 40 below the sprocket wheel 17b so as to be horizontally rotatable.

A spacer collar 38a, which is integral with the wheel shaft 38 and cannot rotate, is interposed between the sprocket wheel 17 and the rotary encoder 39. A large number of rectangular slits 39 are provided at the periphery of the rotary encoder 39.
slits 39a are bored at a constant pitch over the entire circumference, and the slits 39a are connected to a pair of timing pulse generation sensors A and B.
Detected by.

Transmissive optical sensors are used as these sensors A and B in this example, and the light emitting part and the light receiving part are vertically opposed to each other with the peripheral part of the rotary encoder 39 positioned between them. These sensors A.

B is fixed on a common fan-shaped sensor base 41 at a predetermined angle centered on the axis of the rotary encoder 38, and when facing the center of one slit 39a where the optical axis of one sensor is located, the other sensor The optical axis of the slit 39a is in a fixed positional relationship opposite to the side edge of the slit 39a located a predetermined number of layers from the slit 39a.

Therefore, when the rotary encoder 39 rotates, pulses are output from both sensors A and B, but the output timings are not simultaneous (with a predetermined phase difference as shown in FIG. 14).

The sensor base 41 has a base plate 37 centered around the wheel axis 38.
It is rotatably and slidably mounted on the top. This sensor base 41 is provided with a recess 42 at the center of its arcuate periphery and arcuate holes 43 on both sides thereof. The concave portion 42 is fitted with an adjustment eccentric pin 45 that is eccentrically rotatably supported on the base plate 37 by a shaft 44. When the eccentric pin 45 is turned with a screwdriver or the like, the sensor base 41 rotates around the wheel shaft 38. Rotate slightly clockwise or counterclockwise around the center, and both sensors A and B
The positions of are adjusted at the same time. The sensor base 41 is fixed onto the base plate 37 with the fixing screw 46 through the rear circular arc hole 43.

The disk 4 holding the rotary encoder 39
0 is biased upward by a braking spring 47 disposed within its cylindrical portion, the rotary encoder 39 is maintained at a constant distance from the sprocket wheel 17b by the spacer collar 38a, and can rotate relative to the sprocket wheel 17b. At the same time, a predetermined braking force is always applied. A pin 48 is integrally protruded from the upper surface of the disk 40, and this pin 48 passes through an adjustment arc hole 49 of the sprocket wheel 17b and an adjustment arc hole 51 of an adjustment plate 50 attached to the sprocket wheel 17b. are doing. Note that 52 is a reinforcing plate fixed to the upper surface of the sprocket wheel 17b, and this reinforcing plate is also provided with an arcuate hole 53 that is congruent with the adjustment arcuate hole 49 of the sprocket wheel 17b.

The adjustment plate 50 is placed on the reinforcing plate 52 so as to be rotatable and slidable about the wheel axis 38 . This adjustment plate 50 has
In addition to the adjusting arcuate hole 51, a recess 54 is provided on the peripheral edge, and fixing arcuate holes 55 are provided on both sides of the recess. The recessed portion 54 is
It is fitted with an adjustment eccentric pin 57 that is eccentrically rotatably supported on the reinforcing plate 52 by a shaft 56. When the eccentric pin 57 is turned with a screwdriver or the like, the adjustment plate 50 rotates clockwise or counterclockwise around the wheel axis 38. By slightly rotating clockwise, the relative positions in the longitudinal direction of the adjustment arc 51 of the adjustment plate 50 and the adjustment arc hole 49 of the sprocket wheel 17b, that is, their -
The several arc length (the length between one end of the arc hole 49 and the other end of the arc hole 51) L is adjusted. After adjustment, fixing arc hole 55
The adjusting plate 50 is fixed on the reinforcing plate 52 with fixing screws 56 through the fixing screws 56.

Therefore, since the rotary encoder 39 is constantly applied with braking force as described above, the sprocket wheel 17
Even if b rotates, the rotary encoder 39 does not rotate at an angle that allows the pin 48 to move relative to it by the above length (it remains stopped, and beyond that angle it becomes integral with the sprocket wheel 17b). The rotation of the sprocket wheel 17b and the stoppage of the rotary encoder 39 occur every time the sliding direction of the carriage 8 is reversed.

When the sprocket wheel 17b rotates clockwise or counterclockwise depending on the sliding direction as the carriage 8 slides, one end of the adjusting arc hole 49 or the other end of the adjusting arc 51 of the adjusting plate 50 connects to the pin 48. The sprocket wheel 17b and the rotary encoder 39 rotate together in a state where the sprocket wheel 17b and the rotary encoder 39 are engaged with each other.
A pulse with a phase difference shown in FIG. 4 is output. Using these pulses, the sliding direction of the carriage 8 is electrically detected in a well-known manner, and reading from the memory is performed in accordance with the timing. That is, when the pulse of sensor A falls while the pulse of sensor B is in the LOW state, the sliding direction of the carriage 8 is set to the right, and the up/down counter for specifying the address of the memory is counted up by 1. On the other hand, when it falls, the up/down counter counts down by 1 as a leftward movement.

On the other hand, a carriage reference position detection sensor C is disposed at the center of the rear end upstanding wall 2a of the needle bed 2. In this example, a magnetic sensor such as a Hall element is used as the sensor C, and a reference position detection magnet 59 for operating the sensor C is attached to the center of the rear end of the carriage 8.

Therefore, each time the carriage 8 is located at the center of the needle bed 2 and its magnet 59 faces the sensor C, a zero-strand electronic knitting machine obtains one pulse from the sensor C as shown in FIG. The generation of this pulse is used as a reference for the sliding position of the carriage 8, and as will be described later, the pair of sensors A are determined based on this as a reference.

The rising edge of the pulse from B is counted, the readout address of the memory is specified for each knitting needle 60, and the operation of the left and right needle selection solenoids lOa and 10b is controlled for each knitting needle 60.

Since this sensor C is fixedly arranged at a fixed position (center) of the needle bed 2, the time point at which the pulse is output depends only on the carriage 8, and depends on how the carriage 8 and the connecting belt 11 are connected. No, but the pair of sensors A,
The timing of the pulse output of B depends on the accuracy of this connection and the mechanical system from the point of connection to the rotary encoder 39, which also depends on the accuracy of the pair of sensors A, B with respect to the pulse of sensor C and thus with respect to the position of the sensor 60. The time relationship of the pulses varies.

In this electronic knitting machine, roller B is connected to a pair of sensors A based on the pulse from sensor C as described above.

Since the readout address of the memory is specified by B and the operation of the left and right needle selection solenoids 10a and 10b is controlled, the above-mentioned time relationship cannot be maintained with the same degree of precision in either the left or right sliding direction of the carriage 8. and,
It is not possible to accurately select each knitting needle. To do this, as shown in FIG.
The rising point of the pulse of sensor A coincides with the center point of IGH, and the center point of LOW of the pulse of sensor B also coincides, and the pulse of sensor A coincides with the center point of IGH. The rise of knitting needle 6
It is desirable to have a time relationship that coincides with the side edge position of 0.

This electronic knitting machine uses the carriage timing pulse generator mentioned above for this adjustment. ! ! 13, as follows.

That is, first, in FIG. 13, the sensor base 41 is moved clockwise or counterclockwise around the wheel shaft 38 by the eccentric pin 45, and when the sprocket wheel 17b and the rotary encoder 39 are rotated counterclockwise (the carriage 8 is slid to the right). The pulse generation timing of both sensors A and B (strictly speaking, the pulse generation time of sensor A relative to the knitting needle position) is adjusted as shown in FIG. 15. Thereafter, in FIG. 10, the adjustment plate 50 is moved clockwise or counterclockwise around the wheel shaft 3B by the eccentric pin 57, and when the sprocket wheel 17b and the rotary encoder 39 rotate clockwise (the carriage 8 slides to the left) Time)
The pulse generation timings of both sensors A and B are adjusted as shown in FIG.

Next, a solenoid drive circuit for driving the left and right needle selection solenoids 10a and 10b will be described.

FIG. 16 is an electric circuit diagram of the drive circuit, showing left and right needle selection solenoids 10a on the carriage 8 side.

TAB are connected in parallel to each other with respect to the connector 27, and both are grounded by the carriage 8, but these include diodes 61a whose rectifying directions are opposite to each other so that currents with opposite positive and negative currents flow through them. 61b are connected in series.

On the other hand, on the knitting machine main body 1 side, the left and right needle selection solenoids 10a
, 10b, a pair of left and right photocouplers 62a, 62b for needle selection control and a pair of left and right voltage positive/negative switching transistors 63a, 63b are connected in parallel to the plate cable 25 on the left and right sides. For example, a DC voltage of +16V is applied to the emitter of the transistor 63b, while a DC voltage of -16V is applied to the emitter of the transistor 63a. For example, a DC voltage of +5V is applied to the light emitting diodes 64 of the left and right photocoupler 62a, 62b,
Also, according to the pulses from the sensors A and B, the CPU
A left control signal LD is simultaneously input to the left control signal input terminal 66a, and a right control signal RD is input to the right control signal input terminal 66b. These left and right control signals LD and RD are binary signals that can be HIGH or LOW.
As the sliding direction of the carriage 8 is detected as described above by the pulse from B, H
It is inverted from IGH to LOW or from LOW to J(IGH.Incidentally, in this example, when the carriage 8 moves to the right, the right control signal RD is LOW and the left control signal LD is HIGI(
, when the vehicle is going left, the right control signal RD is HIGH and the left control signal LD is LOW. Then, the left and right needle selection solenoids 10a are controlled by these left and right control signal binary signals LD and RD.
, 10b are controlled to be turned on and off as follows.

When both the left and right needle selection signals are HIGH, that is, when a plus 5V DC voltage is supplied to both the left and right control signal input terminals 66a and 66b, both the left and right photocouplers 62a and 62b emit light. The diode 64 does not emit light, and the left and right transistors 63a, 6
3b are both turned off. Therefore, at this time, since neither the +16V nor the -16V voltage is applied to the temporary cable 25, the left and right needle selection solenoids 10
a and 10b are both turned off.

When the right control signal RD is LOW and the left control signal LD is HIGH, that is, when the right control signal input terminal 66b is set to Ov and +5V is applied to the left control signal input terminal 66a, the right photocoupler 62b A current flows through the light emitting diode 64, causing it to emit light, turning on the phototransistor 65, and a current due to the applied voltage of plus 16 V flows through the resistor 67b.

68b and the phototransistor 65 to ground. Therefore, the base potential of the right transistor 63b becomes lower than the emitter potential, and the transistor 63b is turned on. At this time, the light emitting diode 64 of the left photocoupler 62a does not emit light because its anode and cathode are at the same potential, and the left transistor 63a is turned off.

Therefore, a voltage of +16V is applied to the temporary cable 25 via the transistor 63b and the resistor 69 on the right side, which are turned on.
Then, the carriage 8 is further moved by the current collector 27.
Power is supplied to the side. And this voltage of plus 16V is
In the carriage 8, a left and right hand movement solenoid 10a,
10b, the current flows to the right needle selection solenoid 10b due to the action of the diodes 61a and 61b, but does not flow to the left needle selection solenoid 10a, so the current flows to the right needle selection solenoid 10b.
is energized only.

On the other hand, on the contrary, when the right control signal RD is HIGH and the left control signal LD is LOW, that is, plus 5V is applied to the right control signal input terminal 66b, and the left control signal input terminal 66a is set to Ov. Then, a current flows through the light emitting diode 64 in the left photocoupler 62a, causing it to emit light, turning on the phototransistor 65, and a current caused by the application of -16V flowing from the ground toward the phototransistor 65 and the resistors 68a and 67a. Therefore, the base potential of the left transistor 63a becomes higher than the emitter potential, and the transistor 63a is turned on. At this time, the light emitting diode 64 of the right photocoupler 62b does not emit light because its anode and cathode are at the same potential, and the right transistor 64 does not emit light.
3b is turned off.

Therefore, a voltage of -16V is applied to the temporary cable 2 through the turned-on left transistor 63a and the resistor 69.
5, and from there, power is supplied to the carriage 8 side by the current collector 27. And this voltage of minus 16V is
In the carriage 8, left and right needle selection solenoids 10a,
10b, the current flows to the left needle selection solenoid 10a due to the action of the diodes 61a and 61b, but does not flow to the right needle selection solenoid 10b.
is energized only.

Note that both the right control signal RD and the left control signal LD are not set to LOW at the same time.

FIG. 14 shows the timing of energization and deenergization of the left and right needle selection solenoids 10a and 10b in response to the pulses of the sensors A and B. The right needle selection solenoid lOb is connected to the carriage 8.
When the left hand movement solenoid 10a slides to the right, and only when the left hand movement solenoid 10a slides to the left, one cycle is energized and deactivated from the rising edge of the sensor A pulse to the rising edge of the next pulse. subject to force control.

In addition, the above plus 16V, minus 16V, plus 5V

After executing 08, return.

In the data set subroutine 120 in FIG. 26, the pattern data stored in the RAM 73 (data for turning on/off the needle selection solenoids 10a and 10b) is read out, and the needle selection solenoid 10a is set.

This is a subroutine for setting a data flag (DATA) that enables the drive of 10b, and the program is executed according to the following steps. In the case of this example, one piece of pattern data is represented by 1 byte (8 bits), and is stored in RAM.
? 3, 8 bits of data are stored per address.

121...Is C0DE in knit mode? YES
Then proceed to the next step 122.

122...Pattern data stop flag 5TOP
Is it ON? If No, proceed to the next step 123.

123... Adds the value obtained by dividing the contents of the up/down counter UDC by 8 (UDC/8) to the display head pointer DTP of the current stage, and puts the added value into the data pointer DP. That is, the address in the RAM 73 containing the pattern data to be selected is determined.

124...10000000 (2
Enter the base number).

125......The DATA entered at 124 is shown above (U
Shift to the right by the remainder of DC/8).

126...Calculates the logical sum of the shifted DATA and the data specified by the data pointer DP.

In other words, the true pattern data of the above 8 bits is determined.

127...DATA is 0 or 128 if YES.

419...Sounds the buzzer.

As mentioned above, in the knit mode, the data display field 4
．． While displaying the pattern pattern to be knitted, the row of the pattern can be shifted upward or downward in units of 1 row or 10 rows using the forwarding icon Il+12, and the row of the pattern to be displayed and knitted can be arbitrarily selected. .

In addition, when the knit mode is entered, the data flag DATA is turned on because the answer is YES in step 121 in the data set subroutine 120 of FIG. 26 described above.
As a result, the left and right needle selection solenoids 10a and 10b are controlled to be turned on and off as the carriage 8 slides, as described above, by the interrupt routine 100 shown in FIG. At the same time, the count up subroutine 140 in FIG.
a or countdown subroutine 140 in FIG.
The up/down counter UDC is counted up or down by b, and the read address of the RAM 73 is specified. Further, when the sliding direction of the carriage 8 is reversed, the plus 1 subroutine 160 in FIG.
The pattern row number counter PC and the knitting row number counter RC are counted up by a, and the display row of the pattern pattern in the data display WAat is shifted downward one row at a time by the pattern display blue routine 310 of FIG.

Therefore, the row being knitted is always displayed at the bottom of the data display field 4□, and n1 can easily see what kind of pattern is currently being knitted.

In the knitting mode, when the pattern stop icon I6 at the center of the command display [4, is pressed, YES is returned in step 411 of FIG. 34(A), and the process proceeds to the next step 420.

420...Pattern data stop flag 5TOP
Turn on.

When this pattern data stop flag 5TOP is turned ON, the pattern stop icon 1. is displayed as shown in FIG. is reversely displayed from a circular filled form to an unfilled circular form, and since YES is determined in step 122 in the data set subroutine 120 of FIG. 26 described above, the process advances to step 131 and the data flag DATA is turned OFF. Therefore, the answer at step 104 in the interrupt routine 100 of FIG. 25 is NO, and the process proceeds to step 108, where the needle selection solenoid log 10b is turned off, and needle selection based on the pattern data is no longer performed. At the same time, plus 1 subroutine 16 in FIG.
Step 161a in step 0a and step 7" 161b in the minus 1 subroutine 160b result in YES, so the pattern row number counter PC and the knitting row number counter R
C is no longer counted.

Therefore, the pattern stop icon in knit mode! . When pressed to make it a round shape that is not filled in, the pattern data stored in the RAM 73 is ignored when the carriage 8 is slid, and the knitting is done by plain knitting. However, the up/down counter UDC continues to count.

Pattern stop icon 1. When is pressed again, the mode returns from the unfilled round shape to the filled form, the pattern data stop flags ST and OP are turned OFF, and needle selection can be performed in accordance with the needle selection pattern data.

When YES in step 406 of FIG. 34(A), that is, when the set icon ts4 is pressed and the pattern mode icon Ip is pressed, the knitting method (lace knitting, tuck knitting, tuple knitting) selected with the knitting force selection icon Id is selected. etc.) is set to pattern check mode.

Figure 35 is a pattern check routine 500 for normal lace knitting. In the case of normal lace knitting, make sure that the stitches transferred during knitting do not continue for two or more stitches in any of the vertical, horizontal, or diagonal directions. In other words, two or more stitches (squares) filled out (with needle selection data that turns on the needle selection solenoids 10a and 10b) in the data display field 4□ must not be continuous.

Therefore, as shown in Fig. 39, the coordinates of the x and y axes of one stitch (square) on the data display field 4m are set to P, and the coordinates of the one diagonally upper left are P1%. Assuming that the coordinates of one stitch directly above are Pg, the coordinates of the stitch one stitch diagonally above the right are Ps, and the coordinates of the stitch one stitch to the right are P4, the pattern pattern check routine 500 of FIG. Check whether the needle selection data is continuous as follows.

501...The coordinate pointer P is initialized, that is, X is set to 0 and y is set to 1.

502...P's X is the maximum value (MAX) or No
If you select 503, proceed to 504 if YES. Note that MAX is determined by the size of the pattern.

503...P's y remains the same and X is +11
In other words, shift one position to the right.

504... Set X of P to 1, add 1 to y, and shift up one step.

505...Does the hand movement data exist at the specified address of P? If YES, proceed to the next step 506.

506...Is X of P l, that is, the left edge of the pattern?If NO, proceed to 507.Here, if YES, select P
l is a coordinate outside the pattern range and is excluded.

507...The y of P is MAX, that is, the final stage of the pattern, or if NO, proceed to 508, and if YES, proceed to 509.

508... Set this as the coordinate P, leaving -1 and y unchanged from the X of P.

509...P is -1 from X, y is 1, and this is set as coordinate P. Therefore, Pl becomes the first stage.

510...Is there needle selection data at the specified address of Pl? If YES, proceed to the next step 511; if NO, proceed to 511.
1 does not pass.

511...Since there is needle selection data at both coordinates P and P, these coordinates are stored in a predetermined storage area of the RAM 73.

512...Is y of P MAX? No 513,
If YES, the process proceeds to 514; if YES in step 506, the process proceeds to step 512 without going through steps 507-511.

513...Keep X of P as is, add 1 to y, and set this as coordinate P.

514...P's X is left as is, y is set to 1, and this is set as the coordinate P8.

515...Is there needle selection data on P8? YES
Then proceed to 516, and if the answer is No, 516 will not pass.

516...Coordinates P and P! There is needle selection data in both, so store these coordinates.

517...The X of P is MAX, that is, the right end of the side, or No, proceed to 518.

518...The y of P is MAX, that is, the top row of the pattern, or if No, proceed to 519, and if YES, proceed to 520.

519...Add 1 to X and +1 to y of P, and set this as coordinate P.

520...P's X is +1, y is l, and this is the coordinate P.

521...Is there needle selection data in P3? YES
Then proceed to 522, and if the result is NO, 522 will not pass.

522...Since there is hand movement data at both coordinates P and P, these coordinates are stored.

523...Leave y of P unchanged, add 1 to X, and set this as coordinate P.

524...Does P4 have needle selection data? YES
Then, proceed to 525, and if the answer is No, 525 will not pass.

525...za! Since there is needle selection data on both IP and P4, these coordinates are stored.

526...Is both X and y of P MAX?
If YES, proceed to the next step 527; if NO, return to 502 and repeat the same procedure.

527... Stored Kinza IIP, P+,
Pg.

Ps and Pa in the data display column 4. It will blink at the top.

528...Return.

Therefore, when lace knitting is performed, if two or more filled stitches are consecutive in the upper part of the data display field 4, a warning is given by blinking the consecutive stitches.

FIG. 36 is a pattern check routine 600 for tuck knitting. In the case of tuck knitting, do not make more than two tuck stitches in a row horizontally, and in the vertical direction, if you pull up the tuck stitches more than 5 rows, there is a risk of self-drawing, so this must be avoided. As shown in Figure 40, the data is displayed [for one stitch (hanging stitch) on the top].
Let the coordinates of P be the coordinates of 1st, 2nd, 3rd, and 4th step above P+, Pg, Ps, P4, respectively, and the coordinate of one position to the right be PS. The pattern check routine 600 checks the interrelationship of hand movement data in the pattern pattern data as follows.

601...The coordinate pointer P is initialized, that is, X is set to 0 and y is set to 1.

602...P's X is the maximum value (MAX) or No
If you select 603, select YES and proceed to 604.

603...P's y is left as is, X is +1,
In other words, shift one position to the right.

604... Set X of P to 1, add 1 to y, and shift up one step.

605...Is there needle selection data at the specified address of P? If YES, proceed to the next step 606.

606...Keep X of P as is, add 1 to y, and set this as coordinate P.

60T...Is it possible for y of Pl to exceed MAX?

In the case of double knitting using a ribbing machine, one row of the pattern is knitted by two operations of the carriage 8, and the thread exchange between the base thread and the colored thread is performed on one side of the needle bed 2. Therefore, if the odd-numbered row pattern on the data display 41114 is knitted repeatedly, for example, three times, the knitted fabric will be distorted due to yarn exchange.Therefore, in the case of double knitting, a pattern pattern check routine (not shown) for that purpose is required. ) is used to check whether the base threads and colored threads of the pattern are odd or even, and if the rows are odd, that row will be displayed blinking to warn you.

FIG. 37(A), CB) shows the three sensors A.

In the check mode routine 700 for checking the operations of B and C, the check mode is entered from the start mode (Fig. 18) as described above. Then, the check mode screen as shown in Fig. 22 appears, and commands are displayed. 1t
J4. The start mode icon IS and the set icon Ht are displayed, and when the carriage 8 is slid, a rectangular wave pattern according to the operation of sensors A, B, and C is displayed in the data display field 48 as follows. 0 In this example program, the storage area for storing data (HIGH or LOW) from these three sensors A, B, and C is hexadecimal (H) from address 6000 to 6OFF. Secure a street address and 8 of each street (address)
Of the bit data, the 0th bit is set to sensor A, the 1st bit is set to sensor B, and the 2nd bit is set to sensor C. Further, the data of sensor C is always displayed at the center in the horizontal direction. The number of dots in the horizontal direction of the entire LCD 4a is 256 dots as described above.

701...C0DE is set to check mode.

702...Set the LCD 4a to the check mode screen.

703... Stores the start address 6000 (H) in the check data pointer CDP.

704...Check end data pointer CE

705...Is the start icon Is pressed?

If No, proceed to the next step 706.

706...Does the content of the check data pointer CDP match the content of the check end data pointer CEDP? If NO, proceed to the next step 707.

707...Data from sensors A, B, and C (H
(IGH is converted into a binary number and 1 and LOW is set to 0) is stored at the address specified by the check data pointer CDP.

708...Check data pointer CDP 1
Shifts only the lower two digits of the four hexadecimal digits by 1. Therefore, the next address after 6OFF is 6000, and the designated address of CDP is shifted.

709...Limit time.

710... Sensor C has changed from LOW to HIG? If YES, proceed to the next step 711. If NO, return to step 705, and repeat from 706 to 70 until YES.
The process up to 9 is repeated. Therefore, the data of sensors A, B, C are stored sequentially starting from address 6000 until the answer is YES.

711...Check data pointer CDP 1
Convert the lower two digits of the four hexadecimal digits into a decimal number: 128
Shift by (256/2) and store this in the check-end data pointer CEDP. This is because when sensor C goes from LOW to HIC;H, only the latest 128 data of sensors A, B, and C that have been stored up to that point are valid and displayed as described below. . The subsequent 128 items are sequentially stored in step 707. From 711, the process returns to step 705.

If YES is obtained in step 706 through steps 711 to 705, that is, sensor C changes from LOW to HIGH.
If the contents of the check data pointer CDP and the contents of the check end data pointer CHDP match, the 37th
Proceed to step 712 in Figure (B). Therefore, the lower two digits of both pointers are 128 in lO base and match, which corresponds to the center of the horizontal dot number of 256 on the LCD 4a. The processing is performed to display the data of sensor C in the center.

712...The display in the data display column 48 is cleared.

713...The characters 'AJ+rB' and rCJ, which indicate the display stages for sensors A, B, and C, are divided into three stages and displayed. At this time, sensors A and B.

The data of sensor C is not displayed yet. At the same time, the check data display routine 750 of FIG. 38 is entered, and the data of sensors A, B, and C stored in step 707 are displayed as follows.

751... Specifies stage A as the data display stage.

752...The data of sensor A is 1, that is, HI

753... The display stage A is displayed HIGH, that is, all eight dots in the vertical direction corresponding to the stage A are lit.

754...The display stage of A is displayed LOW, that is, only the lowest one of the eight dots in the vertical direction is lit.

755... Specifies the B stage as the data display stage.

756...The data of sensor B is 1 (HIGH
)mosquito.

If YES, proceed to 757; if No, proceed to 758.

757... Display stage B is HIC; H is displayed, that is, all eight dots in the vertical direction corresponding to stage B are lit.

758...The display stage of B is displayed LOW, that is, only the lowest one of the eight dots in the vertical direction is lit.

759... Designates the C stage as the data display stage.

760...Sensor C data is 1 (HIGH)
mosquito.

761 if YES. If No, proceed to 762.

761... The C display stage is displayed HIGH, that is, all eight dots in the vertical direction corresponding to the C stage are lit.

762...The display stage of C is displayed LOW, that is, only the lowest one of the eight dots in the vertical direction is lit.

763...Returns and proceeds to step 714 in FIG. 37(B). Therefore, this step 76 is executed for the first time.
3, the latest 128 pieces of data for each of sensors A, B, and C that were stored until sensor C went from LOW to HIG)I are displayed simultaneously.

714...Check data pointer CDP to 1
to prepare for storing and displaying the next data. As a result, the answer in step 706 becomes No, and new data from sensors A, B, and C can be sequentially stored at the addresses specified by the check-end data.

715...Does the content of the check data pointer CDP match the content of the check end data pointer CEDP? If NO, return to step 750, and continue until YES, that is, until the output of data 256 is completed. The processes 750 and 714 are repeated.

If YES, proceed to 716.

-716...Sounds the buzzer. After this, the process returns to step 703 and the above-described series of processes is executed again.

Therefore, when the carriage 8 is slid to the left or right across the position of the sensor C, the 6 of each sensor A, B, C
256 pieces of data from the 000 (H) address to the 6OFF (H) address are displayed HIGH on each display stage with the sensor C data in the center, as shown in Figure 22.
and displayed simultaneously as a rectangular wave pattern according to LOW (
grid (also displayed), and its display remains unchanged unless the stored content changes. In this case, the above processing of the check motor routine 700 is so fast that the sliding speed of the carriage 8 can be ignored; The length changes depending on the sliding speed of the sensors A and B. When the pulse output relationship of the sensors A, B, and C is mechanically adjusted as described above, the adjusted state is A and B.

This can be confirmed by looking at the display on stage 03.

In addition, in the case of check mode, if you press the set icon It, the data display field 4! The display will be cleared. When the start mode icon Is is pressed, Y is pressed in step 705.
It becomes ES and returns to the start mode shown in Fig. 18.

"Effects of the Invention" As detailed above, according to the method of the present invention, when the carriage is slid, the operating status of various sensors can be displayed between the sensors on the same display device as the display device that displays the pattern. Since the display is displayed in a manner according to the output timing, the operations of various sensors can be easily and simultaneously performed a so-called self-check. Furthermore, since a dedicated display device for checking is not required, it is economical.
