Mainly, in FIG. 5, 71 is a stage feed control mechanism, which can use the device shown in Japanese Patent Publication No. 50-15896. In the present invention, if the relationship between rotational input and rotational output is clear, The detailed internal structure is omitted as it is sufficient for understanding.

That is, in the stage feed control mechanism 71, 72 is an input shaft;
A ratchet wheel 73 and the like are directly connected to this, and a manual knob 74 is connected to it so as to protrude to the left of the auxiliary machine frame 39.

As will be described later, this ratchet wheel 73 is rotated at a constant pitch, so that the input shaft 72
is also rotated by a constant pitch, and the rotational displacement is transmitted to the senna unit output shaft T5 and the millimeter unit output shaft 76 at a gear ratio set via a transmission mechanism included in the stage feed control mechanism 71. It has become.

That is, for the same rotation angle of the input shaft 72, the rotation angle of the output shaft 75 in senna units is a rotation angle corresponding to the horizontal movement setting value of the centimeter unit setting lever 77, and the rotation angle of the output shaft in millimeter units is 76 is a rotation angle corresponding to the setting value of the horizontal movement of the millimeter setting lever 78.

Then, a senna unit output shaft 75 and a millimeter unit output shaft 76
The movable motions of both are combined by a combining gear mechanism 19 and transmitted to a gear 80 that is integrated with the stage feed shaft 42.

), and when the selection switch 149 is selected on the a side, it generates an all selection signal, when it is selected on the b side, it generates a left selection signal, and when it is selected on the a side, it generates a left selection signal. Right side selection signals are generated and applied to the selection input terminal Ic of the write control circuit 146.

Furthermore, when the all selection signal is applied to the selection input terminal Ic, the write control circuit 146 targets one stroke of the sensor 65 and the memory content of the counter 145 is "1".
The count contents (area number) of the counter 145, which are the first and last output signal areas when the read signal is given from the sensor 65 to the signal input terminal Ia, are generated as an output signal from the output terminal O from to r400J. When the left side selection signal is applied to the selection input terminal Ic, the signal input terminal Ia is stored in the external mold data memory circuit 148 while the count content of the counter 145 is from "1" to r200J.
The count contents of the counter 145, which are the first and last output signal areas when the read signal is applied to the external data memory circuit 148, are stored in the external data memory circuit 148, and when the right selection signal is applied to the selection input terminal Ic, the counter When the count contents of 145 are from r201J to r400J, the signal input terminal Ia

This arithmetic circuit 150 calculates the size of the stitches stored in the stitch number gauge circuit 144 which is supplied to the information input terminal Ib each time the stored content of the outer mold data memory circuit 148 is supplied to the signal input terminal Ia. This is converted into the needle number on the needle bed 2, and is generated as an output signal from the output terminal O. This is given to the outer mold end needle memory circuit 151 and outputted from the outer mold end needle memory circuit 151. 151
is adapted to sequentially store the needle number and left/right distinction.

152 is a display control circuit, the input terminal I of which is connected to the output terminal of the outer edge needle memory circuit 151, and the first output terminal Oa is connected to the left edge needle indicator 136 and the right edge needle indicator 1.

is being moved in the counter-arrow C direction, which is the left direction, the needle number corresponding to the forming pattern line 55 located on the right side of the knitting width recording sheet 40 is first stored, but the display control circuit 152 The needle number corresponding to the left mold line is always displayed on the left end needle display 136, and the needle number corresponding to the right mold line is always displayed on the left end needle display 136. It looks like this.

The display control circuit 152 also includes an outer mold end needle memory circuit 15.
When the memory content of the first time is different from the memory content of the previous time, an output signal is generated from the second output terminal ob and this is sent to the buzzer 153.
This causes the buzzer 153 to sound for a short period of time.

Next, the operation of this embodiment having the above configuration will be explained.

First, when using the knitting machine body X and the knitting width indicating device Y together, the knitting width indicating device Y is installed at the rear part of the knitting machine body X,
Connecting body 1 stored in storage recess 135 of auxiliary machine frame 39
28 is lifted and rotated approximately 90 degrees forward, and then pushed down to connect the connecting cylinder 132 to the upper end of the rotating shaft 16 in the machine frame 1.

By the way, when knitting a knitted work using the knitting machine main body X, trial knitting is performed using the knitting yarn used for the knitting, and the stitch gauge is measured.

That is, the numerical value of the length for a given number of stitches varies depending on the knitting yarn used.

In this example, when the stitch gauge of trial knitting using the knitting yarn used for knitting is 60 rows vertically, 18 cm 5 mm (row gauge information) and 40 rows horizontally, 13 cm 2 mm (stack number gauge information) , the senna unit setting lever 77
to the "18" mark on the centimeter scale 85, set the millimeter setting lever 78 to the "5" mark on the millimeter scale 86, and then set the senna unit setting lever 138 to the "13" mark on the centimeter scale 142. , and set the millimeter unit setting lever 139 to the "2" mark on the millimeter scale 143.

Then, in this embodiment, since the forming pattern line 55 is recorded on the knitting width recording sheet 40 at a scale of 1/2, by setting the senna unit setting lever 77 and the millimeter unit setting lever 78 as described above, Input shaft 72 of stage feed control mechanism 71
By rotating at a constant pitch, the knitting width distribution sheet 40 becomes 1,125 WII, which corresponds to 1/2 of the vertical size of the actual stitch.
It will be fed L steps.

On the other hand, based on the settings of the senna unit setting lever 138 and the millimeter unit setting lever 139, the stitch number gauge circuit 144 always supplies the stitch number gauge information to the arithmetic circuit 150 such that 40 stitches is 13 cm and 2 mm. Become.

Then, the knitting width recording sheet 40 is attached to the stage feeding mechanism 41, the punch card 21 is attached to the needle selection control device 18, and the selection switch 149 is selected to the a side, for example, to write all selection signals to the control circuit 146. is applied to the selection input terminal Ic of .

When the carriage 8 is slid, for example, in the direction of arrow A, the rotating body 14 is rotated in the direction of arrow B together with the rotating shaft 16 via the belt 17. The rotation is transmitted to gear 126 in the direction of arrow B.

In this case, the motion transmission mechanism 121 is set to transmit the rotation of the rotating shaft 16, that is, the rotation of the rotating member 14, to the gear 126 at a ratio of 1:10, so that the gear 126 also rotates once when the rotating member 1401 rotates.

The rotating body 14 is connected to the carriage 80 and the 4 knitting needles 3.
The same applies to the gear 126 since one rotation is made by the sliding movement of eight gears.

Also, since the gear 126 is meshed with the gear 102, the gear 102 (the same applies to the gear 100 and the bevel gear 101)
is also rotated in conjunction.

Since the gear 100 that rotates together with the gear 102 is meshed with the gear 98, this gear 93 is also rotated in the direction of arrow B in FIG. 5, and the first rotating ring 87 is also rotated in the same direction via the clutch mechanism 94. , and the sensor base 63 is slid in the direction of arrow C via the belt 89.

In this case, the gears 126, 102, 100 are moved so that the sensor base 63 has a sliding speed that is approximately the same as the sliding speed of the carriage 8, for example.
．． 93, first and second rotating wheels 87 and 88, etc. are set.

Therefore, the sensor 65 attached to the sensor base 63
The area detector 66 is also moved in the direction of the arrow C, the sensor 65 scans one row of the knitting width recording sheet 40 in the direction of the arrow C, and the area detector 66 scans the slit plate 56 in the direction of the arrow C.

Then, when the area detector 66 starts scanning the slit plate 56 in the direction of arrow C, the area detector 66 starts scanning the slit plate 56.
A pulse-like area signal is generated at the boundary between the peaks 57 and troughs 58 of 6, and is applied to the input terminal of the counter 145.
”, “3”, and so on.

In this way, when the sensor 65 scans the left side of the forming pattern line 55 on the knitting width recording sheet 40, the sensor 65 generates a read signal and sends it to the write control circuit 146.
is applied to the signal input terminal Ia of.

If the time point at which this read signal is generated is in the area r100J of the slit plate 56, at this time the counter 145
The counting content is II OOj, which is the sensor 65
When it is determined that it is the first output signal area in one stroke, the write control circuit 146 supplies this counted content r100J from the output terminal O to the outer mold data memory circuit 148 for storage.

Memory content of this outer mold data memory circuit 148 is “100”
is applied to the signal input terminal Ia of the arithmetic circuit 150.

Thus, the arithmetic circuit 150 is connected to the external data memory circuit 14.
Based on the memory content r100J from 8, the center line 60 of the knitting width recording sheet 40, that is, the boundary line 59 of the slit plate 56 is
0” standard area (201-100=1
01 ), and since the width dimensions of the peaks 57 and troughs 58 of the slit plate 56 are female and the forming pattern line is 1/2 scale, the knitted fabric to be knitted is (IOIXIX2=202)m. The actual size of the work is calculated, and then from the stitch count gauge information of the stitch count gauge circuit 144, for example, 40 stitches 132fi (20 ÷ the number of knitting needles 3 required for knitting) In other words, the number of needles counted to the left from number "0" Calculate the number, especially 61 above.
．． If a fraction occurs below the decimal point, such as 1212..., this is rounded up to calculate 62, and this is stored in the outer mold end needle memory circuit 151.

Then, the content "62" stored in the outer end needle memory circuit 151 is given to the left end needle display 186 via the display control circuit 152, and is displayed numerically as "62".

After that, when the sensor 65 scans in the direction of the arrow C and reads the right side of the mold line 55, the point at which the read signal disappears is in the region r301J of the slit plate 56.
At this time, the count content of the counter 145 is r301J,
After this is determined to be the last output signal area at the end of one stroke of the sensor 65, the write control circuit 146 supplies this counted content r301J from the output terminal O to the external mold data memory circuit 148 to store it, and further stores this count content r301J. Content r301
J is applied to the signal input terminal Ia of the arithmetic circuit 150.

Thus, the arithmetic circuit 150 is connected to the external data memory circuit 15.
Based on the memory content "301" from 1, the center line 60 of the knitting width recording sheet 40, that is, the boundary line 59 of the slit plate 56 is
0” standard area (301-200=1
01), and the number of knitting needles 3 necessary for knitting the knitted work in the same manner as described above.In other words, the needle number counted from number "0" to the right is calculated as "62", and this is the number of needles 3 required for knitting the knitting work. Memory circuit 1
51 as a number attached to the right side.

Then, the content "62" stored in the outer end needle memory circuit 151 is given to the right end needle display 187 via the display control circuit 152, and is displayed numerically as "62".

After that, the area detector 66 detects the area r40 of the slit plate 56.
When the load switch 62 is approached after passing through 0J, the built-in permanent magnet activates the load switch 62, so that the stored content of the counter 145 is forcibly set to r401J.

After that, the carriage 8 continues to be slid in the direction of the arrow A, but during this time the sensor base 63 comes into contact with the metal fitting 44 and the sliding movement in the direction of the arrow C is stopped, so the clutch mechanism 94 is cut off. In this state, the rotation of the gear 93 is no longer transmitted to the first rotating wheel 87.

After that, the operator looks at the left end needle indicator 136 and the right end needle indicator 137 provided on the auxiliary machine frame 39, and displays the numerical values before moving the carriage 8 in the direction of the propagation arrow A by operating the carriage 8 in the direction of arrow A. Then, the knitting needles 3 located between the knitting needles 3 numbered on the left side ``62'' and the knitting needles 3 numbered right side ``62'' on the needle bed 2 are manually operated so that they are all at knitting time positions where they should be involved in knitting.

Thereafter, when the carriage 8 is slid to the left in the direction opposite to the arrow A, the knitting work is knitted using the knitting needles 3 between the number 62 on the left and the number 62 on the right.

Also, when the carriage 8 is reversed from the direction of arrow A to the direction of arrow A, the rotating member 14 is reversely rotated from the direction of arrow A to the direction of arrow B through the belt 17, and the bevel gear 101 is rotated accordingly. As the lξ gear 98 is reversely rotated, the lξ gear 98 is reversely rotated from the direction of arrow B to the opposite direction of arrow B.

When the bevel gear 101 is reversely rotated, the inverted constant angle clutch mechanism 1 has a bevel gear 105 that meshes with the bevel gear 101.
The constant angle disc 111 of No. 03 is rotated in the direction of arrow E from the state shown in FIGS. The knitting width recording sheet 40 is fed by one step via the step feed control mechanism 71.

In this case, the row feed pitch of the knitting width recording sheet 40 is 1.125 m based on the row number gauge information.

On the other hand, when the gear 93 is reversely rotated from the direction of the arrow B to the direction opposite to the arrow B, the rotation of the gear 93 in the direction opposite to the arrow B is the first rotation for approximately half a rotation due to the action of the clutch mechanism 94. The sensor base 63 is maintained in contact with the metal fitting 44 without being transmitted to the ring 87 .

Then, during the first approximately half rotation of the gear 93 in the direction opposite to arrow B, the step feeding of the knitting width recording sheet 40 is completed.

Thereafter, when the gear 93 rotates approximately half a turn in the direction opposite to arrow B, the subsequent rotation is transmitted to the first rotating wheel 87 by the action of the clutch mechanism 94, and the sensor base 66 is rotated through the belt 89.
8 is slid in the direction opposite to the arrow C, the sensor 65 scans a new row of the knitting width recording sheet 40 in the direction opposite to the arrow C to read the forming pattern line 55, and the area detector 66
scans the slit plate 56 in the opposite direction of arrow C, and at this time the counter 145 changes from r401'' to r400.
J, r399J, r398J, . . . will be subtracted.

After that, the area detector 66 measures "1" on the slit plate 56.
When the sensor base 63 comes into contact with the metal fitting 43, the reset switch 61 approaches and the reset switch 61 is activated and the contents of the counter 145 are forcibly reset to "0". Sliding in the direction of arrow C is stopped.

Thereafter, in the same manner, the forming pattern line 55 on the knitting width recording sheet 40 is read and the knitted work is knitted based on this, but when the carriage 8 is slid in the direction of the arrow A and the counter-arrow. The knitting needles 3, which are positioned at the knitting time position based on the indications of the left end needle indicator 136 and right end needle indicator 137 described above, are moved by the action of the needle selection control device 18.
As is well known, the punch card 21 is sorted into a first position for knitting and a second position for pattern knitting depending on the presence or absence of a punch hole for displaying the picture pattern 21a. Therefore, in a knitted fabric work, 24 stitches are considered as one unit, and the pattern 21a is
The membrane-like structure is repeatedly knitted according to the time.

As described above, when the number of knitting rows advances and the left and right spacing between the forming pattern lines 55 recorded on the knitting width recording sheet 40 changes, the display control circuit 152 starts to sound the buzzer 153. With the sound, the operator confirms the change in the display of the needle number month on the left end needle display 136 and the right end needle display 137, and then operates to knit based on the changed needle number.

Further, when the knitted work is a front body of a sweater or the like as shown by the forming pattern line 55 as in this embodiment, the following operation is further performed.

That is, when the knitting work progresses and the sensor 65 scans the collar center point 55a of the forming pattern line 55 as shown in FIG. 1, the selection switch 149 is turned to b.
Personally, I select the C side.

Then, the outer mold selection circuit 147 generates a left selection signal or a right selection signal, and the write control circuit 14 receives this signal.
6 stores in the outer mold data memory circuit 148 the counted contents of the counter 145, that is, the area number, where the first and last read signals are generated during each run of the sensor 65 by sliding in the direction of the arrow C or counter-arrow C. When the write control operation is changed, for example, when the selection switch 149 is set to the b side, the first and last read signals are targeted only within the range of area numbers "1" to r200J, which is the count content of the counter 145. Further, when the switch 149 is set to the C side, the first and last judgments of the read signal are made only for the area numbers r201 to r400J, which are the count contents of the counter 145. The count contents of the first and last counters 145 are stored in the outer mold data memory circuit 148.

In either case, the knitting width recording sheet 40
The needle number corresponding to the left side of the mold line 55 is displayed on the left end needle display 136, and the needle number corresponding to the right side is displayed on the right end needle display 137.

Note that if the knitting width indicating device Y is not required when operating the knitting machine main body is removed from the upper end of the rotating shaft 16 of the rotating member 14 on the side of the knitting machine main body X, and then the connecting body 128 is rotated approximately 90 degrees counterclockwise in FIG. By moving this connecting body 128 downward, it is stored in the four storage parts 135.

As a result, the connection between the rotating body 14 on the side of the knitting machine main body X and the drive mechanism 120 on the side of the knitting width instructing device Y is cut off, and the knitting machine main body X can be operated independently of the knitting width instructing device Y. become able to do so.

As described above, according to this embodiment, the rotating body 14 that rotates as the carriage 8 slides is provided on the side of the knitting machine main body X, and is coupled to and detachably from the rotating body 14. A motion transmission mechanism 121 for transmitting the motion of the rotating body 14 to a drive mechanism 120 in the knitting width indicating device Y is provided in the knitting width indicating device Y so as to be rotatable in the horizontal direction. By disengaging the connection between the member 14 and the motion transmission mechanism 121, it is possible to operate the knitting machine body X independently of the knitting width indicating device Y, as well as to control the movement of the rotating member 14 as necessary. If the transmission mechanism 121 is coupled, the knitting width indicating device Y, which is separate from this, can be linked to the operation of the knitting machine main body X, and the needle number of the knitting needles 3 necessary for knitting can be displayed numerically. Moreover, it is extremely convenient because it can be carried out with a simple operation of moving the motion transmission mechanism 121 toward and away from the rotating body 14.

．． 197, a ratchet wheel 198 that is fitted and fixed to the left end of the shaft 192 and corresponds to the ratchet pawl 118 of the reverse constant angle clutch mechanism 103, and a manual dial 199 that is fitted to the left end of the shaft 191. It is composed of.

The inverted constant angle clutch mechanism 103 and the drum 17
9, the stage feeding mechanism 190, etc. constitute a drive mechanism 200 of the needle selection control device 2.

On the other hand, the configuration of the electric circuit will be described with reference to FIG.
The output terminal of the light receiving element 178 is connected to the trigger input terminal T of the flip-flop circuit 202 via a waveform shaping circuit 203 having an amplification function.
The set output terminal Q of No. 02 is connected to one end of a parallel circuit of exciting coils 164 and 164 via an amplifier 204, and the other end of the parallel circuit is grounded.

In this case, the excitation coil 164, 164 is mounted on the slidingly operated carriage 154, and the other electrical components are arranged in the auxiliary machine frame 167, so that the parallel circuit of the excitation coil 164, 164 Both ends of the amplifier 204 are connected to an outlet (not shown) fixed to the carriage 154, and the output terminal and ground of the amplifier 204 are connected to a curl cord (
(not shown), and the other end of the curl cord is connected to a plug (not shown) which is removably plugged into the electrical outlet.

Next, to describe the operation of the above configuration, the motion transmission mechanism 1
The connecting cylinder 132 of 21 is connected to the rotating shaft 16 of the rotating body 14.
If it is separated from the upper end, the knitting machine main body X can be operated independently of the needle selection control device 2, which is the same as in the previous embodiment. A case where the needle selection control device Z is linked to the knitting machine main body X will be described.

For example, when the carriage 154 is slid in the direction of arrow A,
The rotating body 14 is rotated in the direction of arrow B via the belt 17, and based on this rotation, the drive shaft 174 is rotated in the direction of arrow F, thereby rotating the drum 179 and needle pulse disk 176 in the same direction.

In this case, the drum 179 will rotate twice for one rotation of the rotating body 14, in other words, the knitting needles 8 of the carriage 154
The drum 179 rotates once due to the 24 sliding movements of the drum 179, and the elongated hole 179a of the drum 179 moves one step corresponding to the slit 180a of the pattern knitting card 183 by the arrow G in synchronization with the sliding movement of the carriage 154. It will scan in the direction.

When the butt 7 of the knitting needle 3 in the knitting standby position reaches the vicinity of the needle selection position by the electromagnet 161 at the right end of the carriage 154, the pattern is displayed on the pattern knitting card 188 corresponding to the knitting needle 3. When the area around the square 189 is in a light-shielded state, the light from the rung 185 is not received by the light receiving element 187, and the light from the rung 185 is not received by the flip-flop circuit 202.
The input signal at the data input terminal is a low level signal, that is, a logic signal, and is "0", so the output signal at the set output terminal Q is also "0", and the excitation coils 164 and 164 are not energized.

As a result, the butt 7 of the knitting needle 3 that has reached the vicinity of the needle selection position by the electromagnet 161 is guided directly to the first guide path 159 according to the sliding movement of the carriage 154, and the knitting needle 3 captures the first yarn. , and will form a ground group.

Also, the butt 7 of the knitting needle 3 in the knitting standby position is connected to the electromagnet 16.
When the knitting needle 3 reaches the vicinity of the needle selection position according to 1, when the area around the square of the pattern display section 189 of the pattern knitting card 188 corresponding to the knitting needle 3 is transparent with a picture pattern,
The light receiving element 187 receives the light from the lamp 185 and generates an output signal of "1" as a high level signal, that is, a logic signal, which is applied to the data input terminal of the flip-flop circuit 202 via the waveform shaping circuit 201. Therefore, the output signal of the set output terminal Q of the flip-flop circuit 202 is "
1'' and the excitation coils 164 and 164 are energized.

As a result, the butt 7 of the knitting needle 3 that has reached the vicinity of the needle selection position by the electromagnet 161 is guided to the second guide path according to the sliding movement of the carriage 154, and the knitting needle 3 captures the second yarn, forming the pattern. We will organize the edition.

In this way, in response to the sliding operation of the carriage 154 in the direction of arrow A, the drum 179 rotates once in the direction of arrow F every time 3024 knitting needles slide, and one row of pattern knitting cards 188 is repeatedly moved in the direction of arrow G. Based on this scanning, needle selection 3 of knitting needles 3 is performed.

Thereafter, when the carriage 154 is reversely slid in the direction opposite to the arrow A, the rotating body 14 is also reversely rotated in the direction opposite to the arrow B via the belt 17, and based on this, the reverse angle is determined.

'The latch mechanism 103 operates to move the actuating plate 116 back and forth once in the directions of arrow H and counter-arrow H, and the ratchet pawl 118 engages with the ratchet wheel 198 to rotate it at a constant pitch, thus changing the pattern. The knitting card 188 is fed one step by a step feeding mechanism 190.

As the carriage 154 is slid in the direction opposite to the arrow A, the drum 179 is rotated in the direction opposite to the arrow F, and a new row of the pattern knitting card 188 is scanned in the direction opposite to the arrow G. Similar needle selection is performed.

Incidentally, when the carriage 154 is slid in the direction opposite to the arrow A, an electromagnet (not shown) at the left end of the carriage 154 performs needle selection.

As described above, based on the sliding operation of the carriage 154, the knitting pattern corresponding to the picture pattern on the pattern knitting card 18B is knitted into the knitted fabric in units of 24 knitting needles, that is, 24 stitches. .

Therefore, the embodiments shown in FIGS. 10 to 13 can also provide the same effects as the embodiments described above.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the invention.

As described above, the present invention can be operated independently of the knitting machine main body and the knitting auxiliary device, and the motion transmission mechanism of the knitting auxiliary device can be freely connected to and separated from the rotating body of the knitting machine main body. A separate knitting auxiliary device can be linked to the operation of the knitting machine main body with a simple operation of simply turning the knitting device, making it extremely convenient. Can be provided.
