To provide a pattern knitting device for a knitting machine capable of improving workability without giving a sense of anxiety.

Embodiments Hereinafter, the configuration of a knitting machine embodying the present invention will be explained with reference to the drawings.

In FIG. 1, a knitting machine main body 1 includes an elongated needle bed 2 extending in the longitudinal direction, and a large number of comb teeth 3 and knitting needles 4 are alternately arranged in rows at equal pitches over almost the entire length in the longitudinal direction. There is. The butt 4a of each knitting needle 4 is movable in the front-rear direction along the needle groove 2a on the upper surface of the needle bed 2.

A knitting carriage (hereinafter referred to as a carriage) 5 is mounted so as to be able to slide left and right along the rail section 2b on the needle bed 2, and a carriage cover 7 is attached to the upper part of the bed plate 6, and a carriage cover 7 is attached to the front part. A knitted fabric presser 9 is provided with a pair of front and rear yarn feeders 8a, 8b, etc. Furthermore, five push buttons 10 are provided at the center of the front part of the carriage cover 7, and by pressing these buttons alone or in combination, knitting cams for knitting knitting patterns such as two-color simultaneous knitting and tuck knitting can be arranged. It is now possible to choose.

In addition, a needle selection operation knob (not shown) is rotatably provided on the rear right side of the upper surface of the carriage cover 7, and by rotating this knob, the needle selection mechanism can be used for flat knitting, pattern knitting, pattern knitting, etc. It is possible to switch to a state such as one-point pattern knitting.

Next, a cam mechanism arranged symmetrically on the lower surface of the base plate 6 will be explained based on FIG. 2. In this example, the state of the cam mechanism in the case of two-color simultaneous knitting will be explained.

The cam body 11 is horizontally installed near the front of the lower surface of the base plate 6, and a front rest butt passage is formed on the front side thereof. The rear cam body 12 is similarly placed laterally on the lower surface of the base plate 6 toward the rear, and a rear rest butt passage is formed on the rear side. A pair of left and right organizing main cams 13

The card step-feeding pulse motor M1 as a step-feeding member has its drive shaft 20 drivingly connected to the card feed cylinder 18, and rotates the feed cylinder 18 based on a control signal from an electric control circuit. There is.

The pattern card 21, which serves as a recording medium for performing pattern knitting such as two-color simultaneous knitting, is inserted into the card feed cylinder from the card insertion hole 22 formed in the longitudinal direction of the upper surface of the main body cover 1a, as shown in FIG. As shown in FIG. 1, a number of feed holes 23 are formed at both ends to engage with the feed projections 19, and a pattern such as two-color simultaneous knitting is formed in the center. A knitting pattern diagram 24 is provided that constitutes knitting pattern information for each knitting stage for knitting.

A horizontal row in this knitting pattern diagram 24 means, for example, a knitted fabric in two-color simultaneous knitting, and each row of horizontal rows is divided into eight sections, and each square 25 corresponds to each needle position (stitch). means that square 2
The stitches at the needle position corresponding to 5 are displayed in different colors, and the basic pattern for two-color simultaneous knitting is recorded.

As shown in FIGS. 1 and 3, the knitting position detection plate 26 is disposed on the front side of the card feeding cylinder 18, and has eight rectangular detection windows 27 formed therethrough at equal intervals. Each detection window 27 corresponds to 8 in a horizontal row in the knitting pattern diagram 24 of the pattern card 21 sent by the card feeding cylinder 18.
The knitting pattern information displayed within the divided squares 25 can be seen through. Sampling marks 28 are provided below the detection windows 27, respectively.

The sensor running DC motor M2 is capable of forward and reverse rotation, and its drive shaft is connected to a cylindrical cam 29 provided with a spiral cam groove 29a. Follower 30
is engaged with the cam groove 29a of the cylindrical cam 29, and is slidably inserted through a guide rod 31 disposed parallel to the cylindrical cam 29, so that the cylindrical cam 2

A data detection signal based on knitting pattern information of each square 25, that is, each stitch, output from the data sensor 33 is encoded by a data signal output circuit 38 and output as a data signal to a write control circuit 36. The write control circuit 36 stores the data signal in the next full stage memory 39 as needle selection data based on the timing pulse signal.

The all-stage memory 39 as a storage device is a readable and writable memory, and each row address is composed of 8×1 bits, and each row corresponds to each stage in the knitting pattern diagram 24, that is, each knitting stage. In addition, the eight addresses correspond to the eight squares 25 in a horizontal row in each row, that is, to each stitch position in each knitting row. Therefore, knitting pattern information at each stitch position in each knitting row is stored as needle selection data at each address in each row of the full-row memory 39.

A memory read control circuit 40 serving as a read device selects a desired row from among the rows of the full-stage memory 39 based on a read control signal from a central control circuit 42, which will be described later, and reads each address of the row. The stored needle selection data is sequentially read out and transferred to the next readable and writable first memory 41. Therefore, the first memory 41 stores needle selection data for one knitting stage.

The central control circuit 42 constituting the feed control device, etc. is the main calculation circuit of the pattern knitting device including a row number register, etc., and is connected to a knitting start switch SW1 and a knitting end switch SW2 provided at appropriate positions on the main body cover 1a. The knitting start and knitting end signals are input, and the reversal of the position and reversal signals output from the carriage position/reversal detection device 43 which detects the sliding position and reversal of the carriage 5 traveling on the needle bed 2. It is designed to input signals. The central control circuit 42 outputs a control signal to the stage feed pulse motor M1 via the drive control circuit 44 in response to the knitting start signal, knitting end signal and inversion signal. Therefore, by driving the step-feeding pulse motor M1 forward and backward based on the control signal, the pattern card 21
is controlled for stage advance and stage return.

Further, in response to the knitting start signal and the inversion signal, the central control circuit 42 transfers the needle selection data for one knitting row stored in the first memory 41 to a readable and writable second memory 45. ing.
Further, the central control circuit 42 outputs a control signal to the write control circuit 36 in response to the knitting start signal. And write control circuit 3
6 outputs a drive control signal for controlling the rotation of the sensor running DC motor M2 to the drive control circuit 46 based on this control signal, and also outputs each square of the knitting pattern diagram 24 from the data signal output circuit 38. Data signals for each row based on the knitting pattern information of the stitches 25 are sequentially stored as needle selection data in the all-row memory 39 based on the timing pulse signal.

Furthermore, in response to the knitting start signal and the inversion signal, the central control circuit 42 selects a desired row from among the rows of the all-stage memory 39, and selects needle selection data stored at each address of the row. That is, a read control signal for transferring needle selection data of a required knitting stage to the first memory 41 is output to the memory read control circuit 40.

A needle selection solenoid control circuit (hereinafter referred to as a needle selection control circuit) 47 as a needle selection control device responds to a control signal output based on a knitting start or reversal signal from the central control circuit 42, and The needle selection data stored in the memory 45 is read out, and a drive signal for exciting the needle selection solenoid SOL is output based on the needle selection data. At this time, the needle selection control circuit 47
controls which of the needle selection solenoids SOL provided on both sides of the carriage 5 a drive signal is output based on the position signal output from the carriage position/reversal detection device 43. That is, since the carriage 5 of this embodiment is of the forward needle selection type, when the carriage 5 is to be slid from the left side to the right side, the right needle selection solenoid SOL is used, and when the carriage 5 is to be slid from the right side to the left side, the solenoid for needle selection on the right side is used. , left needle selection solenoid
It is designed to output a drive signal to SOL.

Next, the operation of the electrical control circuit configured as described above will be explained.

As shown in FIG. 1, the pattern card 21 is inserted into the card insertion hole 22 with the data sensor 33 disposed on the left side, and the set position, that is, the first horizontal row of the knitting pattern diagram 24 is immediately adjacent to the insertion hole 22. Visible position exposed at the top (distance l above from the data reading position of the data sensor 33 as shown in Fig. 3)
position). Then, when the central control circuit 42 inputs a knitting start signal by operating the knitting start switch SW1, the central control circuit 42
The operation starts according to the flowchart shown in the figure.

The central control circuit 42 first sets a first row number register and a second row number register set inside the circuit 42 to a knitting pattern start row set in advance, for example, "1".
At the same time, all the contents of the full-stage memory 39 are cleared to "0". Next, the central control circuit 4
2 outputs a control signal to the step feed pulse motor M1 via the drive control circuit 44 based on the content of "1" in the second step number register, and outputs a control signal to the step feed pulse motor M1 via the drive control circuit 44 to move the pattern card 21 to the first row horizontally in the knitting pattern diagram 24. The pulse motor M1 is rotationally controlled so that the data is stepped from the visual recognition position to the data reading position.

After the first row of the knitting pattern diagram has been advanced to the data reading position, the central control circuit 42 stores the start row "1" in the all-stage memory 39 based on the content of "1" in the second row number register. The DC motor M2 for running the sensor is rotationally driven in order to read the knitting pattern information of the first horizontal row in the knitting pattern diagram 24 by reciprocating the sampling and data sensors 32 and 33 in the right direction. A control signal for the write control circuit 36 is output to the write control circuit 36. As a result, needle selection data based on the knitting pattern information of the first row horizontally in the knitting pattern diagram 24 is stored in each address of the start row "1" of the full-stage memory 39.

When the data sensor 33 moves forward to the right side and reads the knitting pattern information of the first row horizontally, the central control circuit 42 reads all the knitting pattern information to check whether all the knitting pattern information of each row in the knitting pattern diagram 24 has been read. Check the end signal output from the detection device (not shown), for example, based on the signal that detects the end mark on the card, and if it is determined that the knitting pattern information of all the rows has not been read yet, the knitting pattern diagram 24 A control signal is output to the step-feeding pulse motor M1 to move the next step, that is, the second horizontal row, to the data reading position, and a write is written to increment the all-step memory 39 to a line feed, that is, the first address of the second row. A control signal is output to the input control circuit 36. In addition, the central control circuit 42 moves the data sensor 33 on the right side back to the left side, and then moves it back to the right again.
A drive control signal is output to the sensor running motor M2 via the write control circuit 36 in order to cause the sensor 33 to read the knitting pattern information of the second horizontal row.

Therefore, in each address of the second row of the full-stage memory 39, each knitting pattern information of the second row horizontal row of the knitting pattern diagram 24 is stored as needle selection data.

Thereafter, the central control circuit 42 stores the knitting pattern information for all rows of the preset knitting pattern in the knitting pattern diagram 24 in each address of each row of the full row memory 39 in the same manner as described above.

When the knitting pattern information of all the rows in the knitting pattern diagram 24 is stored in the all-row memory 39 as needle selection data and the end signal is output from the all-row reading detection device, the central control circuit 42 registers the row number first register "1", a control signal is output to the step-feeding pulse motor M1 via the drive control circuit 44, and the pattern card 21 is moved so that the first horizontal row of the knitting pattern diagram 24 comes to the visible position. returns the stage, and outputs a read control signal to the memory read control circuit 40 based on the content of "1" in the second stage number register, and stores it in each address of the start row "1" of the all stage memory 39. The needle selection data, that is, the needle selection data based on the knitting pattern information of the first horizontal row, is read out and written into the first memory 41, and the needle selection data stored in the first memory 41 is further transferred to the second memory 45. to be forwarded to.

Subsequently, the central control circuit 42 transfers the contents of "1" in the second stage number register to the first stage number register, and increments the contents of the second stage number register by "2" after the transfer. The central control circuit 42 outputs a read control signal to the memory read control circuit 40 based on the incremented content of "2", and reads the needle selection data stored in each address of the second row of the full-stage memory 39, that is, The needle selection data based on the knitting pattern information for the second horizontal row is read out, and the data is stored in the first memory 41 and rewritten with the previous needle selection data.

Next, the central control circuit 42 tries to feed and control the pattern card 21 so that the first horizontal row of the knitting pattern diagram 24 comes to the visible position based on the content of "1" in the first row number register. Since the pattern card 21 has already been moved back in the previous processing operation,
In this case, perform the following processing operation.

When the carriage 5 is slid, for example, from the left side to the right side with the first horizontal line in the knitting pattern diagram 24 in the visible position, the needle selection control circuit 47 is activated by the central control circuit based on the knitting start signal from the knitting start switch SW1. 42 and the position signal from the carriage position/reversal detection device 43, the second memory 45
The needle selection solenoid on the right side of the carriage 5 reads the first stage needle selection data and selects the knitting needles 4 related to knitting as the carriage 5 slides.
The first formation stage (start stage) is formed by controlling the excitation of SOL. In this embodiment, at the start of knitting, when knitting the start stage, the carriage 5 placed on the left side of the needle bed 2 is slid to the right side, or the carriage 5 placed on the right side is slid to the left side. , at the start of sliding, the carriage position/reversal detection device 43 may output a reversal signal to the central control circuit 42, but even if it does, the central control circuit 42 will not be able to detect the reversal signal based on the start of formation of the start stage. Only the signal is invalidated, and the next programming operation is not performed in accordance with this inverted signal.

After the carriage 5 has been slid to the right side and the formation of the start stage has been completed, it is turned back to the left side and the carriage 5 is reversed, and a reversal signal is output from the carriage position/reversal detection device 43 to the central control circuit 42. . In response to this inversion signal, the central control circuit 42 transfers the needle selection data based on the knitting pattern information of the second horizontal row in the knitting pattern diagram 24 stored in the first memory 41 to the second memory 45, and transfers the needle selection data to the second memory 45. At the same time, the content of "2" in the second stage number register is transferred to the first stage number register, and the content of the second stage number register after the transfer is incremented to "3". Next, the central control circuit 42 outputs a read control signal to the memory read control circuit 40 based on the contents of "3" in the second stage number register, and reads the organization stored in each address of the third row of the all stage memory 39. 3rd of pattern diagram 24
The needle selection data based on the knitting pattern information for one horizontal column is read out, and the data is stored in the first memory 41 to be rewritten with the previously stored needle selection data.

The central control circuit 42 outputs a control signal to the step feed pulse motor M1 via the drive control circuit 44 based on the content of "2" in the first step number register, and controls the second step horizontally in the knitting pattern diagram 24. The pattern card 21 is advanced in steps so that one row comes to the visible position. Therefore, the stitch pattern of the second row to be knitted can be immediately understood by observing the knitting pattern information of the second horizontal row located at this visual recognition position.

When the carriage 5 is slid from the right side to the left side in this state, the needle selection control circuit 47 receives a control signal from the central control circuit 42 based on the reversal signal and a position signal from the carriage position/reversal detection device 43. reads out the needle selection data for the second horizontal row stored in the second memory 45, and activates the needle selection solenoid SOL on the left side of the carriage 5 to select the knitting needles 4 involved in knitting as the carriage 5 slides. The second knitting stage is knitted by excitation control.

After the carriage 5 has been slid to the left and the formation of the second formation stage has been completed, when the carriage 5 is turned back to the right and runs in reverse, a signal is sent from the carriage position/reversal detection device 43 to the central control circuit 42. An inverted signal is output. Thereafter, the knitting of each knitting stage is carried out in the same manner as described above. After the knitting of each knitting stage is completed, each time the carriage 5 is reversed, the needle selection data of the knitting stage to be knitted from now on is stored in the first memory 41. Needle selection data for the knitting row to be knitted next is read out from the all-row memory 39 and stored in advance in the first memory 41, and when knitting is performed based on the second memory 45, the number of rows is In accordance with the contents of the first register, the pattern card 21 is moved step by step for each knitting so that the row horizontal row in the knitting pattern diagram 24 corresponding to the current knitting step comes to the visible position.

Next, when the knitting end switch SW2 is operated to end the knitting based on the knitting pattern diagram 24, a knitting end signal is input to the central control circuit 42. In response to this knitting end signal, the central control circuit 42 returns the pattern card 21 to the set position so that the first horizontal row of the knitting pattern diagram 24 comes to the visible position.
Wait for the operation of knitting start switch SW1 for the next knitting.

As described above, according to this embodiment, every time one stage is organized, the read control circuit 40 controls the memory 39 for all stages.
The needle selection data based on the knitting pattern information for the next knitting read from and previously stored in the first memory 41 is stored in the second memory 45, and the needle selection data stored in the second memory 45 When knitting is performed based on the needle selection data, the pattern card 21 is advanced in steps so that the step in the knitting pattern diagram 24 corresponding to the needle selection data is placed at the visible position. It is possible to immediately grasp what kind of stitch pattern and at what position the rows are knitted, and it is possible to improve work efficiency without giving the worker a sense of anxiety until the knitting is completed.

Although the carriage 5 of the forward needle selection method was used in this embodiment, it may also be applied to a knitting machine using a knitting carriage 48 of the backward needle selection method, as shown in FIG. The present invention may also be applied to knitting in which a color scheme slip stitch knitting is performed using a pattern card on which knitting pattern information is recorded. In the case of backward needle selection, the stage of knitting pattern information corresponding to the current needle selection stage appears at the visible position, confirming that needle selection had been performed accurately before knitting each stage. can do.

Alternatively, a set line may be provided at an appropriate position on the lower side of the knitting pattern diagram 24 to serve as the set position of the pattern card, and the pattern card feeding may be controlled using the set position as a reference at the start and end of knitting. .

Furthermore, in this embodiment, the data sensor 3
3, when reading the knitting pattern information for each row horizontally in the knitting pattern diagram 24, the sensor 33 reads each knitting pattern information when moving forward from the left side to the right side, but when it moves back from the right side to the left side. Even when the knitting pattern information of the next row is read and stored in the all-row memory 39, the reading speed of the all-row knitting pattern information in the knitting pattern diagram 24 may be shortened.

Effects As detailed above, according to the present invention, it is possible to immediately grasp what stitch pattern and position of the knitting row to be knitted at the time of knitting, and the worker This has the effect of improving workability without giving a sense of anxiety until the knitting process is complete.
