Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand-striping machine that automatically controls knitting needle selection according to a needle selection program signal from a storage device, and has a control device that visualizes the contents of the storage device on a video device. It concerns hand knitting machines.

In electronically controlled hand knitting machines, needle selection information (patterns, molding patterns, etc.) or other control information (letters and numbers) stored in ROM or RAM cannot be visually confirmed. It is possible. As a read-only memory element, a so-called ROM (abbreviated as an integrated circuit) is used, in which combinations of individual knitting needle signals corresponding to striped patterns are configured and stored in a program, and as the knitting progresses, the ROM is The conventional automatic needle selection control system obtains knitted fabrics with patterns according to the content data of each ROM by sequentially issuing needle selection signals according to the program and controlling knitting needle selection according to the discussion signal. It was difficult to knit while checking the needle selection signal contained in the ROM.
In addition, when checking whether the overall knitting pattern is correct, it is necessary to separate needle selection information for each row, and
To do this, it was necessary to turn over the knitted fabric as shown in Figure 10A and look at it. Furthermore, when checking the position of the needles, it was necessary to check each needle one by one, making the operation extremely troublesome. The present invention was proposed in order to eliminate the above-mentioned drawbacks of the conventional technology, and the needle selection information for one stage is made to correspond to the horizontal axis of the video device, and the "1" and "0" of the needle selection information are used to represent the strength and weakness of the luminance signal. Alternatively, it is an object of the present invention to provide a hand knitting machine in which the pattern is displayed using color signals, and as the rows progress one after another, the vertical axis moves by the amount of movement of the rows, so that the pattern can be displayed as a whole in a two-dimensional display.

In addition, the present invention is capable of not only visualizing the pattern, but also molding information and operation instruction numbers, characters, etc., using the same video device, and incorporates the video device in order to improve the handling and operability of the video device. The purpose is to provide a dew-type visible type hand-striped machine.

The embodiments of the drawings will be explained below. In FIG. 1, the flow of electrical signals is shown by the solid line path connecting each element of the mechanism unit 1 in the left frame line and the control circuit 2 in the right frame line, and the broken line is an overall diagram of the system showing the mechanical operational relationships.

The basic part of the present invention in this control system is to add several new components found above the stone in the control circuit 2 to the existing technology, thereby changing the needle selection information for one stage. In order to display the knitting pattern two-dimensionally, instead of only displaying the knitting pattern, needle selection information, which is video data, is extracted in synchronization with the video synchronization signal. In order to understand this, the entire control system will first be explained in comparison with the figures from FIG. 2 onwards. FIGS. 2 to 7 explain the structure and operation of each part of the mechanism section 1. First, the explanation will start from this part. When the lowering cam 7 of the carriage 6 rides on the butt portion 4b of the striped needle 4 under pressure, the leaf spring 5 is released and the needle tail end 4a is lowered as shown by the solid line in FIG. Needle tail end 4 when rolled down in this way
A plurality of needle selection plates 8 and index plates 9 are juxtaposed perpendicularly to the knitting needles 4 at the positions where they engage with the knitting needles 4. The length corresponds to all the rows of knitting needles 4, or the index plate 9
Some of them are binary coded as described below and have lengths corresponding to each role. The transparent needle plate 8 is provided with cam parts 10 at predetermined intervals on each plate. The predetermined spacing of the cam portion 10 is such that the knitting needles in the same order of each block are arranged in parallel on each needle selection plate 8.
As shown in FIG. 5, the cam portions 10 of the adjacent needle selection plates 8 are arranged so as to be regularly shifted from each other in correspondence to the adjacent knitting needles 4. However, in relation to this mismatch, the spatial arrangement of the adjacent green needles 4 and the actually adjacent knitting needle plates 8 does not necessarily have to be an arrangement in which the cam parts 10 are linearly shifted, and the order of control operations may vary. It is good as long as it is in place. Also, the rope needle plate 8 has a spring 1 1
When the needle tail end 4a descends, the needle tail end 4a engages with the cam groove 10a of the cam portion 10, and the displacement movement of the needle selection plate 8 due to the cam action resists the spring 11. occurs in the direction FIG. 3 illustrates the operational relationship between the rope needle 4 and the cam portion 10 at this time. The post-reducing operation of the weaving needles 4 by the lowering cam 7 is thus transmitted as a displacement movement of each needle selection plate 8, and when the needle selection plate 8 is not restrained in any way, as the reduction cam 7 passes, The knitting needles 4 are returned upward by the leaf springs 5, and the needle selection plate 8 is returned to the previous position by the springs 11. When the needle selection plate is held in its displaced state, the needle tail end 4a is gripped and held by the cam groove 10a as shown in FIG. By the action of the needle selection cam 12 accompanying this, the needle selection positions are assigned to the front and back as shown schematically in the upper left part of FIG. 1, as a suitable example. In this embodiment, each block of eight knitting needles 4 corresponds to the eight needle selection plates 8 sequentially and in parallel and overlappingly for each flock. Therefore, the total number of needles is 200. In this case, each needle selection plate 8 is provided with 25 cam portions 10.

On the other hand, there are five index plates 9, and as mentioned above, each of the five index plates 9 plays the role of being binary coded, and each one corresponds to one digit of the binary number. It is arranged as follows. This means that in a 5-digit binary number, the above 2
This corresponds to each of the three divided knitting needle blocks, and as shown in the middle partial view and the lower schematic diagram of Fig. 5, the first index plate KI has needles arranged A sawtooth cam 1 is placed at a location that repeatedly corresponds to each block in the order.
It has 3. Equipped with sawtooth car 3. Serrated cam 1
3 are arranged in parallel corresponding to each needle in the corresponding block, and when the rope needle tail end 4a descends along the oblique side of the mirror-tooth cam 13, the index plate 9 is displaced laterally by the cam action. , provides an action directed against the force of a spring, not shown in this figure, which biases in the direction of the arrow in FIG. The same displacement action is given no matter which of the green needles 4 in the corresponding block is pushed down, and the pushing cam 7 is always
The actual knitting needles 4 are simultaneously rolled down, so that as long as the rolling down cam 7 is on the knitting needles in the same block, the index plate 9 corresponding to that block responds so as to continue to maintain its displaced state. Below, on the second index plate K2, a sawtooth cam 13 corresponding to the second and third needle blocks is provided, and then two blocks are left open, and the second block has a keytooth cam 13. On the third index plate K3, a sawtooth cam 13 is provided that corresponds to the fourth to seventh needle blocks, and from there repeat, and the fourth index plate K4 is 8
Each index plate 9 of KI to K5 has a sawtooth cam 13 in the arrangement as shown schematically at the bottom of FIG. It is equipped with The correspondence relationship of each plate with the needle block can be said to be that the five index plates 9 correspond to the binary relationship with the needle block expressed in decimal notation, and therefore, the correspondence of each plate from KI to K5. Knowing the combination state of displacement operation, which needle block should the lowering cam 7 be placed on?
It is possible to know whether there exists. Each of the needle selection plate 8 and the index plate 9 can be displaced through the cam action accompanying the striped needle pressure of each plate by engagement between the fishing groove 14 formed in each plate and the support rod 15. The amount of displacement is regulated by the engagement of the pin 16 with the slot 17.

Each plate is configured such that the displacement in the direction against each spring is detected by detection switches 18 and 19 for each plate. For example, as shown in FIG. 6, the means converts the movement of the combined plates through actuators 20, 21 of the switches 18, 19 into open/close signals for the open path, like a so-called limit switch. In this case, each actuator 2 is attached to each plate that is not in a combination correspondence relationship.
A window 22 is provided to allow the windows 0 and 21 to pass through as they are so that they have no relation to each other. In the embodiment shown in FIGS. 5 and 6, the needle selection plate 8 and the index plate 9 are
An example is shown in which the directions of displacement are opposite to each other, and the switch 18 for detecting the displacement of the needle selection plate 8 and the displacement detection switch 19 for the index plate 9 are both actuators 2.
The sensitive directions of 0 and 21 are also set to be opposite to each other. The relationship between the displacement actuation amount of each plate and the response timing of the detection switches 18 and 19 is set so that the displacement detection signals of about three knitting needles 4 that are simultaneously rolled down by the rolling down cam 7 are always aligned. As described above, the eight transparent needle plates and the five index plates 9 correspond to each cam portion 10 and the sawtooth cam 1.
3 is provided with a means for converting the pressure of the corresponding bran needles 4 into electrical signals, and these 13 electrical signals in total serve as input signals to the control circuit 2. However, as will be described later, the index signal l which is the displacement detection signal of the index plate 9
sl to ls5 are the combinations of index signals lsl to ls5 generated under the pressure of the end needle on the entry side when the lowering cam 7 enters the general needle of the knitting from the outside of the rope in each stage of knitting, and is This command is given to a command to display a recorded portion of required data from among needle selection pattern data recorded in a memory element, which will be described later. The displacement detection signal of the needle selection plate 8 is calculated by the control circuit 2, and based on the calculation output, the needle selection plate 8 is selectively subjected to restraint control to remain in the displaced state. For example, the seventh
As shown in the figure, electromagnets 23 are arranged in one-to-one correspondence with each needle selection plate 8, and the mutual operations between the respective needle selection plates 8 are linked by one actuating rod 24. As illustrated in FIG. 7, the actuating rod 24 is swingable around a fulcrum hole 26 passing through the support plate 25, and one end thereof is connected to the engagement hole 27 of the needle selection plate 8, and the other end thereof is Each of the electromagnets 23 is engaged with the head hole 29 of the plunger 28, and its movement in the longitudinal direction is regulated by the electromagnet support plate 30 and the needle selection plate front plate 31. In addition, all of the rhombic needle plate 8 and index plate 9 and the operating rod 24, which do not have a corresponding relationship,
Similarly, mutually independent windows 32 are provided on each plate side, and the actuating rod 24 passes through the windows 32 so that they do not engage with each other. The electromagnet 23 on the left side of FIG. 7 is shown when the corresponding needle selection plate 8 is displaced and the plunger 28 enters the inside of the electromagnet, and the one on the right side is shown when the needle selection plate is inactive and the plunger 28 is moved. It is in a state where the amount of exposure is large. Therefore, when the electromagnet 23 in the state on the left side of the figure is excited by the calculation output of the control circuit 2, the plunger 2
8 is fixed and held in the internal state by magnetic force, and while the electromagnetic excitation continues, the corresponding needle selection plate 8 is restrained and held in the displacement operating position by the holding force, and the needle selection plate 8 that is being restrained holds the corresponding needle selection plate 8 directly below the target. As described above, the rope needle held by the rope needle is subjected to the needle selection action of the needle selection cam 12, which distributes the needle forward and backward. The configuration of the mechanism section 1 on the left side of FIG. 1 and the roles of each of its sections have been explained above.

Next, details of the control circuit 2 will be explained based on FIG. 8 and subsequent figures. The circuits shown in FIGS. 1 and 8 show an example of the implementation of the present invention, in which the stored data in the memory element in which the needle selection program signal constituting the knitting pattern is recorded is read out, and the knitting needle is read out in accordance with the needle selection signal that has been set. be controlled.

It also shows what corresponds to the basic gist of the present invention, which is to convert the ticket selection signal into a video signal when the system is not being organized. However, in FIG. 8, each of the input signals from the diamond throat plate displacement detection switch 18 (hereinafter referred to as handle plate signals) is represented as Gsl to Gs8, and each of these is input to the pulse shaping circuit of FIG. The pulse signals converted into pulse signals via 33 are shown as GI to G8, and the pulse shaping circuit 33 is omitted in FIG. The ROM 34 that stores the needle selection program signal corresponding to the striped pattern is typically a read-only memory (Read-Only Memory) as a type of integrated circuit element.
The needle selection data for one stitch is stored in each of the memory bits arranged vertically and horizontally. That is, the ROM 34, which stores the needle selection data constituting the pattern in a vertical and horizontal manner, can be said to replace the punch card in the needle selection device of the conventional rope machine. However, the ROM 34 used here outputs a predetermined number of stored data in parallel for each read command operation, and in this embodiment, the number of parallel output data is for every 8 stitches. The equivalent is used. Hereinafter, commanding to read data for 8 stitches of a desired part from the data stored in the ROM 34, that is, equivalent to 1 block of the previous life, will be called an address, and the command to read data for 8 stitches of a desired part from the data stored in the ROM 34 will be referred to as an address. The storage location will be referred to as a ROM address. In connection with the progression of the organization stage, the following explanation will be continued by assuming that the process of leaving behind one column of stored data that has been read in the ROM and moving on to reading the next column is called a line feed. RO as mentioned above
Since this is a replacement for the conventional power card for the M34, a plurality of ROM elements are prepared in the position of the ROM 34 in the control circuit 2 according to each knitting pattern, and they can be replaced with each other in a plug-in type. By doing so, the silk pattern can be changed. That is, the position of the ROM 34 in the figure is either a place that accommodates a removable and replaceable ROM element (not shown) or a storage circuit that accommodates one ROM element and is in a state where data can be retrieved from it. It means. ROM
An address switching circuit 62 and a line feed switching circuit 59 for instructing an address when reading data from 34 are provided in the previous stage, and an address instruction circuit 35 and a line feed command circuit 36 for instructing a line feed are further provided in the previous stage. It is being Both are composed of integrated circuits, and are generally
This is similar to a circuit called a down counter.
The address command circuit 35 specifies the address to the ROM 34 with a 5-bit binary encoded output, and in this embodiment, the number of addresses is 29 corresponding to the needle block, 2 in total.
The stored data for one row of 0, female and 10 stitches is read out one after another for 8 stitches. As an input for switching these address outputs one after another, a direction discrimination circuit 37 is provided which discriminates the traveling direction of the carriage 6 and provides a switching signal for either side at the border of each needle block at its left/right discrimination output terminal. There is. When the carriage 6 moves towards the end needles being knitted from outside the middle of the stripe,
As a means for initially addressing the address corresponding to the needle block to which the end needle belongs, the index signal ls1 is used as described above.
~ls5 are connected as inputs in parallel, and a rolling start detection circuit 38 is provided to command the input timing. That is, the index signals lsl to ls5 are input to the address command circuit 35 only when the end needle is pressed down, and thereafter the output addresses are sequentially switched in accordance with the address switching signal from the direction discrimination circuit 37. , and when carriage 6 leaves the middle of the green, OF
The IJ set signal RO from the reset circuit 39 applied to the F input terminal resets all outputs to atmosphere. First, let us begin by explaining the rolling start detection circuit 38.The output of the OR element 40, which produces an output no matter which one of the pulse-shaped handle plate signals GI to G8 is input, is input to the set input of the set-reset type flip-flop 41. In addition, the output thereof is pulse-shaped via a monostable multipipulator 42, and is used as a command signal for reading timing of the index signals lsl to ls5.

After the carriage gives one address operation in this way when the end needle enters, the set state of the flip-flop 41 does not change during knitting, and therefore the monostable multipipe layer 4
2 does not generate an in-desk read signal until the next set operation of the flip-flop 41. When the flip-flop 41 is in the set state, the address switching circuit 62 selects the address command circuit 35 and the line feed switching operator 59 selects the line feed command circuit 36. The direction determining circuit 37 determines the carriage traveling direction in each green stage, and
This is a command signal means for switching the readout address of the OM one after another to the side in the direction of travel, and so that the switching always operates in response to the address boundary, the handle plate signals GI to G8' are activated at the boundary.
This is a configuration of a logic circuit that detects the direction of each order. In other words, if the green needles are lined up in order from right to left in each block, from 1 to 8, then at the border between blocks, the shift from the 8th needle to the 1st needle in the pressure order means the carriage moves to the left. At this time, the AND element 43 detects the logical product of the handle plate signal G8 and GI. However, in this case, it is not possible to determine whether the movement is to the left or to the right by simply establishing the logical product of the handle plate signal G8 and GI, and in order to know the order of the transition, a set-reset type flip-flop 44 is connected to one of the AND inputs. is provided as a gate control element, the flip-flop is first reset with the signal G7 of the 7th hand, and then set with the signal G8 of the 8th hand to open the AND gate. The AND output with the needle signal GI provides an address switching signal to the left side of the address corresponding to leftward movement to the address command circuit 35. At the same time, the flip-flop 46 provided at one input end of the AND element 45
First, a reset is given with the second needle signal G2, and then it is set with the first needle signal GI, and when the gate of the AND element 45 is opened and an AND output is generated with the eighth needle signal G8, this corresponds to rightward movement. Address command circuit 35 as an address switching signal
The configuration is such that it is added to the right switching input end of the switch. The reset terminals of the left and right flip-flops 44 and 46 are connected to the IJ set signal RO, which is generated when the carriage moves out of knitting, and is connected to the respective logical sums of the IJ set signals G7 and G2 of the previous stitch. ing. Next, the line feed command circuit 36 will be explained.

This is to switch the binary encoded output one after another to give the command for the row to the ROM 34. For example, with the 8-bit binary encoded output, it is possible to command the cutting of up to 25 mochimori, that is, up to 25 rows. It is something. It has three input ends,
The line feed input terminal is connected to the IJ set signal RO from the reset circuit 39, and although the mechanism for generating the reset signal RO has not yet been explained, it is generated every time one stage of composition is completed, and the line feed is thereby caused. This is what is being promoted. The remaining two inputs are commanded by means such as manually operated switches (not shown), and as described above, the line feed command circuit 36 is also an up/down counter. That is, the above-mentioned line feed input gives an up signal, and these two manual inputs both give a down signal, and one of the down signals gives a repeat command such as returning only one step, that is, canceling a line feed. and the other commands a return to the first formation start stage, which is obtained by resetting the counter of the line feed command circuit 36. In this way, the address command for the address and the line feed command are input to the ROM 34, and according to the address, the stored contents of the ROM 34 for one block, that is, the needle selection signal, are read out to the output end in parallel for 8 stitches at a time. be done. The read needle selection signals are distributed to the needle selection synchronization circuit 48 as needle selection instruction signals MI to M8, respectively. Next, the transparent needle synchronization circuit 48 will be explained.
Each needle selection calculation unit is composed of needle selection calculation units having the same configuration, and each needle selection calculation unit receives the input needle selection instruction signals MI to M8 and the magnet 23 for controlling each needle selection plate on the output side. It has been combined accordingly. Each needle selection calculator sends an excitation instruction signal PI to the electromagnet when the logical product of both outputs of the two set/reset type flip-flops 49 and 50 is established during the set operation.
~P8, and the output operation is not immediate depending on the handle plate signal corresponding to the leading needle that starts to be lowered as the carriage progresses, but the handle plate signal of the leading needle is output depending on the needle selection instruction signal MI~M8. If the content of the needle instruction signal is to select a needle through logical product comparison with each corresponding one, one flip-flop 49 is first operated to the set state, and then the next one is operated in the order of pressure applied. When the handle plate signal corresponding to the needle arrives, the remaining flip-flop 50 is activated as a set, and both flip-flops at that time. A control output signal is obtained by determining the AND of the outputs of 49 and 50. By doing this, the corresponding electromagnet 23 is This prevents the excitation operation from starting.

To explain this using the item corresponding to the n-th needle in the block, the set input on the flip-flop 49 side has an AND
The result of the AND judgment of the handle plate signal Gn and the needle selection instruction signal Mn is inputted through the element 51, and at the same time, the handle plate signal Gn is connected to the reset input terminal of the other flip-flop 50 in a relationship that provides a reset. Then, the handle plate signal G of the n+1st needle or the n11th needle adjacent to the nth needle
The flip-flop 50 connected to the set input terminal receives the set signal via the OR element 52 which performs the logical sum operation of n+1 and Gn-1, and the set states of both flip-flops 49 and 50 are aligned as described above. The AND element 53 determines the excitation instruction signal Pn to the output increase circuit 54.
give. The output state of the signal Pn is 3 from the time of output operation.
The flip-flop 49 is reset by the arrival of the handle plate signal Gn+4, which is held by the number of needles and delayed by four needles from the nth needle connected to one of the OR elements 55 connected to the reset input of the flip-flop 49. It is canceled by this. A reset signal RO from the reset circuit 39 is connected to the OR element 55 in parallel with each of the eight needle selection calculators, so that when the carriage completes one row of knitting and leaves the knitting stage, On the outside of the end needle, the flip-flop 4 is used instead of the follow-up reset signal Gn+4, which is no longer generated due to the disappearance of the lower needle.
9 is reset. Continuing to explain the reset circuit 39, the output of the OR element 56 which performs an OR operation on any of the outputs of the eight logical bond judgments is connected to the inverter 57.
Each AND element 5 obtains the logical product of the eight elements by a circuit inverted by
8 are input connected with corresponding pairs of combinations of the handle plate signals Csl to Gs8 which do not pass through the pulse shaping circuit 33 mentioned above and respective inverted versions of the excitation instruction signals PI to P8. There is. In this circuit, the OR element 56 outputs to any of the 8 inputs, but when looking at the output from the inverted overall RO side, it appears to be a logic pure operation in which all 8 inputs become null. It can be said that the reset signal RO is output. Regarding the fact that the signal RO output in this way means the end of each knitting row,
Each of the AND elements 58 generates an output in response to the handle plate signal Gsn corresponding to the needle being pressed by the lowering cam 7 under the condition that the needle selection calculator output Pn is not generated. In this case, the first needle under pressure in the direction of movement of the lowering cam 7 does not yet generate the excitation instruction signal Pn, which is the needle selection calculation output, and as the lowering cam advances, the first needle under pressure that follows the first needle is selected for the first time. Comparison calculation with the needle instruction signal Mn becomes operable. Therefore, as long as the pressing cam 7 is within the stripe, outputs will be generated one after another to the AND elements 58 corresponding to the leading needles being pressed. Of course, the excitation instruction signal Pn is not generated for the handle plate signal Gn when the corresponding needle-through instruction signal Mn is not given in addition to the leading needle, so the AND
The element 58 is in the output state, but regardless of the presence or absence of such conditions, there is always an output in one of the AND elements 58 in the series, and therefore the OR element 56 is also in the output state. Considering the silk middle end needle on the exit side when the carriage 6 comes out of the knitting, if it is the leading needle under pressure, it is unlikely that it will be in an uncontrolled state. Of course, even if the lowering cam 7 advances further, there will be no lower needles to be pressed after the end needle, so
In the end, the end needle on the exit side is not subjected to needle selection control, and the output operation state of the AND element 58 corresponding to the end needle on the exit side is changed after the lowering cam 7 has passed over the end needle. When the pressure is released, the handle plate signal Csn corresponding to the end needle disappears, and the output is changed to non-output, and at this time, all eight AND elements 58 are set to non-output. That is, the reset circuit 39 outputs a reset signal RO, which is distributed to each related circuit as a signal corresponding to the completion of one stage of formation as described above. What has been explained above is an example of the basic configuration of an automatic needle selection control system based on the comparison calculation between the lower pressure handle plate signal for the lower pressure needle and the data recorded in the ROM 34, and the output of the calculation. A knitting pattern can be automatically obtained in accordance with content data corresponding to a selected needle pattern recorded in advance in a ROM element (not shown).

Next, a description will be given of the means for visualizing the gist of the present invention, that is, the means for providing the contents recorded in the ROM as a wing needle signal during knitting, and for visualizing the needle selection signal on a video device during non-knitting.

As shown in FIG. 10A, the pattern of the knitted fabric during knitting can be visually recognized by turning the knitted fabric upside down. In addition, when displaying images on a video device, the image must be shown in the normal position (Fig. 10 C), but even if the knitted fabric pattern created by knitting and the pattern created on the video device is the same, the video device The method for extracting needle selection signals during knitting differs depending on the video system. Here, as one of the typical video systems, the matrix display type found in plasma display devices and liquid crystal displays is shown in Figure 10, but this system is relatively flexible in the order in which needle selection signals are taken out during knitting. There is. Another example of the video system is the television sweep system shown in FIG. 10, which is widely used as a video system for commercial televisions and the like.
In this case, in order to produce the same pattern, the video information must be such that the needle selection signal is taken out from the top of the pattern, and the needle selection signal must be taken out from the bottom of the pattern when knitting rope. In other words, the y-axis (stage) direction is reversed. Also y
In the hand knitting machine of this embodiment, the direction of the axis (grain) is the first direction.
As shown in Figure 0 A, the needle numbers are smaller on the right and larger on the left, so the method to retrieve the needle selection signal is to
It can be set so that the 34 addresses are sequentially retrieved by counting up. In a normal knitted fabric pattern, the relationship between the left and right positions with respect to the needle bed is reversed. A needle selection signal is issued based on the address number in the ROM 34, and the knitted fabric is on the left side, and the address number increases toward the right side. The order in which the needle selection signals are taken out in synchronization with the 102nd sweep is that the left side is first, then the right side, and so on. It turns out that the order can be done in the same way. One embodiment of this method will be described with reference to FIG. In order to further clarify the roles and functions of the address switching circuit 62 and the line feed converting circuit 59 in FIG.
The data selector 63 selects the output of the counter 64 and the output of the address command circuit 35, and addresses one of the outputs to the ROM 34. The configuration is such that the selection can be made based on the output C mark of the flip-flop 41 indicating that knitting is in progress. The data selector 60 of the line feed switching circuit 59 is configured to be able to select between the output of the 8-bit counter 61 and the output of the line feed command circuit 36, and the selection command can be selected by the output of the flip-flop 41. Reference numeral 47 denotes a video data register, into which the 8-bit needle selection signal output from the ROM 34 is inputted by the output signal OS6 of the monostable pipelator 70, and the output signal OS2 of the oscillator 66 is used to input the 8-bit needle selection signal.
Go to Bitbuf Serial.

It has a so-called parallel-series exchange configuration. Here RO

are connected.

Note that this oscillator 66 stops oscillating when the train is organized, and continues to oscillate when the train is not organized. The output signal OSI of the oscillator 66 is connected to the inputs of a frequency divider A68 and a frequency divider B69, and the output signals OS5 and OS4 of the respective frequency dividers are obtained. has been entered. A timing chart of these output signals is shown in FIG. The output signal OS2 of the 1/8 frequency divider 67 is divided by 1/8 of the oscillator frequency, and provides a count input of the counter 64 and a clock input of the video data register 47 for serial exchange. The output OS6 of the monostable multipipulator 70 has 1/
The front green trigger of the 8 frequency divider output OS3 is activated.

Also, the frequency divider A68 divides the frequency of the oscillator 66 to create the horizontal synchronization signal OS5, and the frequency divider B69 divides the frequency of the oscillator 66.
It divides the frequency of 6 and generates the vertical synchronization signal OS4. In order to set the timing for transmitting the video synchronization signal SYC and the video data, the horizontal synchronization signal OS5 is connected to the clear terminal of the counter 64, and the horizontal synchronization signal OS5
If this occurs, the counter 64 will be cleared.

On the other hand, since the horizontal synchronization signal OS5 is connected to the clock input of the -bit counter 61, the 8-bit counter 61 counts down by one. Also, the vertical synchronization signal OS4 is connected to the load terminal of the 8-bit counter 61, and when the vertical synchronization signal OS4 acts, the 8-bit counter 61
indicates 240 steps of "171615 Mountain Buddha Q Mountain Melon". The video circuit 78 receives the synchronization signal of the video command unit 65 and the video register 4.
7, a video signal synthesis circuit 73 generates a video signal and sends it to a receiver 80. Also, horizontal synchronization signal OS5 and vertical synchronization signal OS4
The video synchronization signal SYC is synthesized by the synthesis circuit 71.
, and is configured to provide it as a synchronization signal to the video signal synthesis circuit 73. The video data levels "1" and "0" of the video data register 47 are included in the video signal as a luminance signal by the video signal synthesis circuit 73. Further, for color video, there is a burst circuit 72 for color burst signals and a color switching circuit 74 for providing a chromaticity signal, and the output, which is video data, is connected to the R terminal of the color switching circuit 74, which sets the red color. When the color is green, it is connected to the G terminal, and when it is blue, it is connected to the B terminal, and the color is configured so that the color is set when the level of video data is "1" by the color cut-off circuit 74. Also, level "0" can be set manually by resistor 7.
Two colors are displayed by setting resistance values of 5, 76, and 77. Next, to explain the operation, when the unit is not assembled, the video command unit 6
5, an address cutoff circuit 62, and a dead row switchover circuit 59 each perform operations for video.

Since the flip-flop 41 is inactive, the data selector 63 of the address gate circuit 62 supplies the output data of the counter 64 to the ROM 34. On the other hand, line break cutting fusuma circuit 59
The data selector 60 instructs the ROM 34 to change the output data of the 8-bit counter 61 to a new line. At the same time, the oscillator 66 is caused to oscillate, and the vertical synchronization signal O, which is the output of the frequency divider B, is
S4 takes effect and sends a signal to the 8-bit counter 61 to set 181716 to 0 snake Butsuyama 1 (240 steps), and now preparations are made to retrieve the needle selection information on the 24M row.

Further, 8-bit data, which is the content read out from the ROM 34 by the OS 6 output from the monostable multipipulator 70, is input in parallel to the video data register 47.

Next, the oscillator output OS2 registers the video data register 4.
The 8-bit data contained in the oscillator 7 is sequentially output in series and sent to the color switching circuit 74, and when the number of pulses of the oscillator output OS2 becomes 9, the output OS3 of the 1'8 frequency divider acts and becomes monostable. Activate the multipipulator 70. The output OS6 of the monostable multipipulator 70 causes the counter 64 to count by 1, gives a new address to the ROM 34, and at the same time inputs new 8-bit data from the ROM 34 into the video data register 47 in parallel. Next, in the same manner as the previous time, the 8-bit data in the video data register 47 is output one after another by eight pulses of 9 to 16 pulses of the oscillator output CS2.

When the number of pulses of the oscillator output OS2 reaches 17, new data in the ROM 34 is sent one after another as video data to the color cutting fusuma circuit through the video data register 47 in the same manner as the previous time. Next, the number of pulses of the oscillator output OS2 is 20.
When it becomes 0, it means that information corresponding to the needle selection signal for 200 stitches (one row) for one row during knitting has been extracted. The oscillator output OS2 is now on standby until the next horizontal line signal is input, and this time corresponds to the horizontal retrace time of the scanning beam of the television. The three output terminals of the color cutting screen circuit 74 are connected to the input of the video signal synthesis circuit 73, and provide chromaticity and luminance signals.

In addition, if the image is only black and white, the color switching circuit 74 can be omitted, but the image signal can be made into three independent signals of red, green, and blue and sent to the red, green, and blue generating electron guns of the receiver, respectively. If this is done, the video signal synthesis circuit 73 becomes unnecessary. Also, the interlaced scanning by beam sweeping of television is performed by the combining circuit 711.
Although timing is created in this way, detailed explanation will be omitted since it has no particular relation to the present invention. In addition, although only the needle selection signal was explained in the above description, it is also possible to use control information (for example, numerical display, character display), etc. as a visualization signal. Furthermore, the transparent needle signal can be handled not only as pattern information but also as forming information. In the embodiment described above, the needle selection signal processes one bit for each stitch (one stitch), but it is also possible to process multiple bits for one striped stitch by slightly changing the control circuit. It is easy to understand that this is possible. Next, in FIG. 12, an electronic visible type hand knitting machine 79 has a built-in small television 81 which is an example of a video device. In addition, the hand knitting machine 79
Since the functional block 82 has the same configuration as described above, detailed explanation will be omitted. Reference numeral 83 denotes a control circuit for producing images, which includes the image command unit 65, the address switching operator 62, the line feed switching operator 59, and the image circuit 78. Now, when the video signal obtained by the 20 pulses of the oscillator output OS2 is displayed on a television receiver, it becomes one horizontal scanning line.

Next, a method for synthesizing video signals will be described. The standard NTSC image signal, which is the video format of this embodiment, is the format currently used in domestic color televisions. This system will be explained below, but detailed explanation will be omitted since it is well known and is not the gist of the present invention. On the other hand, the color displayed on the TV is dyed by setting two colors: the color of the selected side stitches and the color of non-leech stitches, and the color of the selected stitches is determined by the needle selection signal. This corresponds to when the level is "1".

Also, if the output of the video data register 47 is connected to the input R of the color switching circuit 74, the color will be red, if it is connected to the input G, the color will be red, and if the output is connected to the input G, the color will be red.
When connected to , it becomes blue. Now, temporarily connect the input signal and change the color of the needle signal "1" to red. Next, the color is set by setting the resistance values of the chromaticity correction resistors 75, 76, and 77 to set the color of the needle selection signal "0". In order to temporarily set the color to green, the level of the chromaticity correction resistor 76 is raised to produce a green color. The video signal is a color signal from a color switching circuit 74, a preset luminance, and a burst circuit 72 having a color subcarrier oscillation circuit.
and the synchronization signal SYC of the synthesis circuit 71.
A video signal is obtained by a video signal synthesis circuit 73 that synthesizes signals. When this video signal is connected to a television antenna, an image appears on the television using the television's receiving circuit. Therefore, when the 200th stitch of the knitting stage is imaged, the needle selection signal "1" becomes red and the needle selection signal "0" becomes green, forming one line. Next, when the time during which the scanning line goes blank due to the horizontal synchronization signal ends, the 8-bit counter is subtracted by 1 counter by the horizontal synchronization signal OS5, and the RO
Execute the line feed command for M34 23 Mochimori.

Also, the 25-decimal counter is cleared, and the preparation for extracting the needle selection information of 23g; is completed. Similarly to No. 24, the 8-bit data read from the ROM 34 is input in parallel to the video data register 47, output in series by the oscillator output OS2, and the data is sent to the color switching circuit. When the number of pulses of the oscillator output OS2 is 200,
This means that all the needle selection information for the 23rd gong was sent as a video date. This data is sent out as a video signal by the video signal synthesis circuit 78. On the television screen that receives this signal, the third scanning line is scanned because it uses an interlaced scanning method. This interlaced scanning method is also well-known and detailed explanation will be omitted, but the composition stage N, the scanning line number M, and M=2×240-(Su-1) or M:2×2
There is a 40-(ga) relationship, and the relationship is repeated alternately. Therefore, when the composition stage is 23 tablets, the scanning line number is the 5th, and it is possible to perform the composition stage one after another up to 25 stages, but in this embodiment, due to the actual scanning surface of the television, only 1 scanning line number is set. It is designed to display images from the 240th stage to the 240th stage. The same result as described above can also be obtained when the small television 81 is built-in. Next, the operation process for controlling the selection of knitting needles 4 will be briefly described below.

When the carriage 6 is given a traversing motion on the needle bed 3, the knitting needles 4 in the bran nakana, which are pushed down by the rolling down cam 7, have their tail ends 4
a, the needle selection plate 8 and the index 9 are operated to be displaced according to the predetermined combinations described above.

As a result, handle plate signals Csl to Gs8 and index signals Isl to Is5, which are the displacement detection signals from each of the detection switches 18 and 19, are sequentially generated and given as input output signals to the control circuit 2. The index signal lsn is a combination of the binary codes, and the end needle at the beginning of knitting in each line row is RO.
It means which address in the memory data of M34 it belongs to, and it is sent to the ROM 34 via the address command circuit 35.
It instructs to read the recorded data within the address corresponding to the end needle. The reading of the index signal lsn is controlled to be input into the address command circuit 35 by a signal from the rolling start detection circuit 38 so that it operates only in response to the pressure applied signal of the end needle at the beginning of rolling. It is not involved in the command of the proposed address until the knitting start end needle is under pressure. After commanding the read address of the ROM 34 with the knitting start end needle, the direction of movement is determined by the direction determining circuit 37 as the lowering cam 7 advances, and the output of the direction determining circuit 37 is determined at the boundary of the flock to which the knitting needle belongs. The signal causes the binary value output from the address command circuit 35 to be incremented one after another, thereby switching the starting address of the ROM 34 to the left or right.
When the lowering cam 7 comes out of the end needle at the end of each rope run, the end needle is released from under the shaft, and the reset circuit 39 detects that the corresponding handle plate signal Ssn has disappeared, and the reset circuit 39 outputs the reset signal. The signal RO is sent to the ROM 34 via the line feed command circuit 36.
Switch the proposal to the next column. Furthermore, ROM3
When starting knitting from the beginning of the memory pattern No. 4, a reset is given by manual operation. Also, if you wish to repeat a line correction by one line in the middle of the line, you can move back one column in the ROM 34 by subtracting the count operation of the line feed command circuit 36 by 1 using manual operation input. can. Among the input signals involved in the address command control, the handle plate signals GI to G8 other than the handle plate signals Csl to Gs8 to be input to the reset circuit 39 are
This pulse is passed through the pulse shaping circuit 33 as a pulse synchronized with the rise of the closing signal of the detection switch 18 in response to the displacement operation of the detection switch 18 . In this way, the data for transparent needles and non-needle selection for each of the 8 needles stored in the specified cutting address from the ROM 34 is output as read signals SI to S8, and the resulting output is a needle selection instruction signal. Needle selection synchronization circuit 4 as MI~M8
given to 8. The needle selection synchronization circuit 48 outputs handle plate signals Gn corresponding to the leading needles in the order in which the knitting needles 4 are pressed by the pressing cam 7.
First, the preliminary preparation for the synchronization calculation is performed. When the reduction cam 7 successively applies pressure to the next needle, the corresponding needle selection instruction signal Mn is synchronized with the arrival of the handle plate signal Gn±1 of the adjacent pressure reduction needle.
When a logical operation is performed and the result instructs needle selection, a logical product is established in the AND element 53 and an excitation instruction signal Pn is output, which is the underpressure that generated the previous handle plate signal Gn. It corresponds to the transparent needle plate 8 which is in a combination relationship with the needle, and applies excitation via the output increasing circuit 54 to the electromagnet 23 which is in a moving relationship with the displacement operation of the transparent needle plate 8 in the corresponding relationship. As a result, the electromagnet 23 adsorbs and holds the plunger 28 in the advanced position, thereby transmitting the previous handle plate signal ○n through the needle selection plate 8 that is the moving partner.
The corresponding knitting needle 4 is held under pressure, and while the knitting needle 4 is held in the pressed state, the knitting needle 4 is subjected to the needle selection action of the lozenge needle cam 12 accompanying the reduction cam 7. When the needle selection instruction signal Mn instructs non-selection with respect to the pressure handle plate signal Gn, the excitation instruction signal Pn is not generated, and as the reduction cam 7 passes overhead, the knitting needles of the non-selected needles move upward under pressure. It returns to the direction and is not subjected to the cam action of the needle selection cam 12. The knitting needle 4, which is held under pressure due to needle penetration, is moved to one gate holding flipflop of the AND element 53 by the arrival of Gn14, which is the fourth needle under pressure signal counted from the previous handle plate signal Gn. By resetting the electromagnet 49, the excitation of the electromagnet 23 is released, and the holding state of the electromagnet 23 is released. When the lowering cam 7 moves out of the rope after one-stage knitting, the end needle on the exit side always has no next lower needle to be pressed, so it remains in the lowered state regardless of the content of the corresponding needle selection instruction signal Mn. It is not held, and when it returns upward as the shoshita cam 7 passes, it is detected and the I from the set circuit 39
The J set signal RO resets the remaining gate holding flip-flops 49 that output the excitation instruction signal Pn. Since the present invention is configured as described in detail above, it is possible to use a conventional electronically controlled hand knitting machine in which needle selection information, etc., which is the content stored in a static storage device such as a ROM, is built-in. This has the great effect that the pattern to be knitted can be visually recognized, rather than the pattern that is the needle selection information not being directly visible. In particular, displaying originally two-dimensional patterns in a two-dimensional manner allows you to feel the sense of the pattern more realistically, so it is important to know the design aspect or hobby sense before creating the knitted fabric pattern. It has the excellent effect of being able to Furthermore, when using the hand knitting machine of the present invention, there is no need to take the trouble to set up a TV or the like, and there are also advantages such as ease of viewing since the video device is at hand. As described above, the present invention does not display needle selection information for only one row,
In order to display the knitting pattern two-dimensionally, the needle selection information, which is video data, is extracted in synchronization with the video synchronization signal, and the needle selection signal is converted into a video signal when knitting is not in progress. be able to.
