Regarding a needle selection unit number setting device that sets the number of needle selection units in a knitting machine that selects knitting needles according to
The number of knitting needles can be grouped according to the number of needle selection units programmed on a predetermined recording medium such as a card, and thereby the number of knitting needle groups involved in one unit pattern knitting can be arbitrarily changed. To provide a needle selection unit number setting device which can arbitrarily set the number by recording on the above-mentioned predetermined recording medium and can easily know the current number of needle selection units.

The present invention will be explained in detail below using illustrated embodiments in which the invention is applied to a home-use hand knitting machine.

First, the overall outline of the hand knitting machine to which the present invention is applied will be explained with reference to Fig. 1.The knitting machine main body X has its needle bed
On the rear side, a part of the control panel 2 is exposed, and by inserting the organization program card 1, which is an information recording medium, into the part facing the control panel 2, it can be loaded so that it can be automatically transferred and displayed on it. A reading device A equipped with a scanning member (not shown in FIG. 1) that optically scans the recorded information is installed, and on the control panel 2, one of the components of the device of the present invention is installed. A needle selection unit number display means B is provided, and left and right needle selection range setting switch actuating pieces 31.3 r are optionally provided on the needle bed Although not shown in FIG. 1, the knitting pattern on the knitting program card 1 is displayed on the back side of the base plate 4 of the carriage Y, which is mounted on the carriage Y and runs on the needle bed X. A pair of left and right knitting needles that use electromagnetic force to effectively sort the knitting needles arranged in rows on the needle bed X back and forth according to the direction of movement of the carriage Y according to the electrical signal obtained by scanning. The sorting mechanisms are arranged at a predetermined length apart on the left and right sides.

The reading device A has a scanning member mounted on a carriage Y.
(More specifically, when the carriage Y is placed on the switch activation piece 31 or 3r)
By automatically scanning the recorded information horizontally and linearly, a corresponding electrical signal is output, and the subsequent processing of the electrical signal is now performed using an electronic configuration. Further, power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms by a cord 6 that is passed through a tension member 5 that applies tension to the knitting yarn, and the carriage Y is connected to the switch activation piece. 31
．． By making the knitting needles reciprocate beyond the left and right sides of 3 r, only the knitting needles within the spacing range of switch actuating piece 31.3 r are subjected to effective sorting action (even those within this range are brought to a rest position where they are not subjected to any sorting action at all). (with some exceptions).

First, let's talk about the mechanical configuration of the reading device B.
This will be explained in detail with reference to FIG.

The reading device A as a whole is mounted on a frame 7 below the control panel 2. First, the information recording medium transfer device therein, that is, the device for loading and transferring the organization program card 1, will be explained. frame 7
Endless sprocket belts 81 and 8r, which serve as recording medium supports, are mounted so as to be able to circulate on the left and right sides.

The sprocket bells l-8l and 8r have sprockets 8' protruding from their outer circumferential surfaces at a constant interval to fit into the left and right perforations 1' of the knitting program card 1, and these left and right sprocket bells l-8l and 8r have ) 81.8
Insert the card 1 from the card slot 9' facing on the control panel 2 between the card guide plate 9 and the card guide plate 9, which has a U-shaped cross section and is arranged below between them.
By fitting the perforation 1' to the sprocket 8', the sprocket belt can be supported in a U-shaped bent state, and in this supported state, the pulse motor a installed on the right side of the frame 7 By being circulated by the card 1, the card 1 can be transferred in the direction in which the perforations 1' are arranged.

That is, each sprocket bell) 8 1 , 8 r corresponds to the lower large pulley 10 1 , 1 as shown in FIGS. 4 and 5 (the belts 81 and 8 r are partially cut away).
The hook is turned between Or and the small pulleys 11l and 11r diagonally above it, and furthermore, the left and right large pulleys 101
, 1Or is the drive shaft 12, and the left and right small boo 'J 11
1 and 11r are connected to each other by a rotating shaft 13, and furthermore, a gear 12' fitted to the drive shaft 12 and a gear a' fitted to the shaft of the pulse motor a are meshed with each other. As the pulse motor a rotates, the left and right sprocket belts 8 1 and 8 r circulate simultaneously.

Therefore, the pulse motor a is capable of forward and reverse rotation, and the forward and reverse direction of the drive shaft 12 is determined depending on whether the pulse motor a is driven forward or backward. (Figure 3, bottom) This determines whether to send in the opposite direction.

As mentioned before, the card 1 is inserted through the card slot 9' on the control panel 2, and the slot 9' is
As shown in FIG. 2, a transparent plate 25 is placed on the front side of the raised portion 2' of the control panel 2, and a gap suitable for passing the card 1 is provided between the raised portion 25' at the rear end and the front surface of the raised portion 2'. It is configured by arranging it so that it can be used.

A horizontal reference line 25'' is provided on the upright portion 25' of the transparent plate 25, and the card 1 is positioned using this reference line 25'' as a reference.

A finger shaft 14 is fitted onto the drive shaft 12, with a portion of the finger shaft 14 protruding upward through the window hole of the control panel 2. By turning the handle, the card 1 can also be transferred manually.

As mentioned above, the card 1 optically scans horizontally and in a straight line, and if there are any irregularities on the line to be scanned, the accuracy of reading the information recorded on the card 1 may be compromised. In order to prevent this, a card receiving plate 24 is provided between the left and right sprocket bells.

Therefore, the portion of the card 1 along the card receiving plate 24 is
The left and right sides are flat over almost the entire length.Next, a traveling drive mechanism for driving the scanning member to scan the card 1 horizontally and linearly in this flat portion will be explained.

Two upper and lower guide rods 27 and 28 are horizontally suspended in parallel to each other on the frame 7, and a scanning member is mounted on these so as to be able to slide left and right.

That is, as shown in FIG. 4, the scanning member has left and right through holes 29° provided in its main body, the running body 29, slidably fitted into the upper guide rod 27, and the running body 29
The bobbin 30 integrally provided on the lower side of the lower guide rod 28
It is fitted in a slidable manner.

A coil 31 is wound around the bobbin 30, and a horizontally long permanent magnet 32 is placed slightly below the lower guide rod 28 in parallel therewith.

The entire length of the upper side of the permanent magnet 32 is, for example, an N pole, and the entire length of the lower side is an S pole.The lower guide rod 28 is made of a magnetic material, and when a current is passed through the coil 31, the current is , the permanent magnet 32 crosses the magnetic field that is constantly created, and the traveling body 2 is moved by the magnetic force acting between them.
9. The scanning member therefore moves automatically to the left or right along the guide rods 27, 28 depending on the direction of the current flowing through the coil 31.

That is, the coil 31 and the permanent magnet 32 are
This constitutes a type of linear motor with 2 serving as a stator.

At positions corresponding to the left and right ends of the permanent magnet 32, as shown in FIG. 6 (cross section taken along line II-II in FIG. 3), left and right limit switches 331 act to switch the polarity of the current flowing through the coil 31.゜33 r is placed.

The limit switch 33l on the left side is turned on when the scanning member collides with the left row, and the limit switch 33r on the right side is turned on when the scanning member collides with the right row. The left and right limit switches 331 and 33 r move left and right, and these left and right limit switches serve as the left and right stroke ends, and as will be described later, the scanning member is always located at the left stroke end. is the original position, and in conjunction with the reversal of carriage Y, it moves rightward from its original position at a considerable speed to the right stroke end, and as soon as it reaches the right stroke end, it immediately reverses ( The left and right limit switches 33l and 33r are designed to automatically and continuously feed back the scanning member to its original position (turning back) to its original position. It also functions as a means for detecting whether or not the stroke is at the stroke end.

As shown in FIG. 4, the leading edge of the upper extension 29' of the scanning member running body 29 faces the card receiving plate 24 at a close position, and has a reading element, that is, a light emitting element, at the leading end. A so-called photoelectric sensor C is installed therein, which is comprised of a photodetector element and a light-receiving element that receives reflected light that is reflected from the surface of the card and converts it into an electrical signal.

As the scanning member travels, its photoelectric sensor C optically scans a straight line along the card receiving plate 24 of the card 1. Hereinafter, the photoelectric sensor C will be referred to as a scanning sensor. Make it.

Next, card 1 will be explained with reference to FIG.
On the white surface in between, a knitting pattern recording section 1p, which is a part for recording the knitting pattern, and
The function information recording area on the right side, that is, the function mark entry field 1f, which is the area where the function mark is recorded, is set in the same color as the emission color of the light emitting element of the scanning sensor C, which the light receiving element does not discriminate (for example, as the light emitting element). It is created by displaying the grid division lines (red when red light emitting diodes are used) in advance using an appropriate display method such as printing, and is read by the scanning sensor C on the left side of the knitting pattern entry field 1p. A large number of feed control marks 34, which can control the amount of feed of the card 1 by controlling the amount of feed of the card 1, are placed, for example, with slightly thick horizontal black lines at regular intervals in the direction in which the perforations 1' are arranged. It can be recorded in advance by displaying it at a specific time.

The spaces between the entry fields 1p and 1f and between the entry field 1p and the feed control mark 34 are blank.

In the above-mentioned knitting pattern entry field 1p, the vertical lines of the grid dividing lines that constitute it are the dividing lines between the stitches, and the horizontal lines are the dividing lines between the knitting rows, and below the outside of the field, The numbers representing the stitches are displayed in the same color as the grid dividing lines.

More specifically, in the knitting pattern entry field 1p, one minimum section, that is, a witness grid corresponds to one stitch,
The horizontal arrangement, or row, corresponds to one knitting needle, and the vertical arrangement, or row, corresponds to a knitting row (wale), and n horizontal rows of stitches are considered as one group. When knitting so-called unit patterns, the vertical line at the left edge and the vertical line n vertical lines to the right are regarded as the boundary line, and a picture (knitting pattern) corresponding to the unit pattern to be knitted is drawn between them. is drawn solidly in black using an appropriate writing instrument such as a pencil, as shown in the figure.

For example, when knitting a unit pattern of 12 horizontal stitches by selecting 12 knitting needles as a unit of one group, the range from the left vertical line to the 12th vertical line It is meant to draw a picture inside.

At this time, as long as the outline of the picture is within the above range, the inside of the picture may be filled in solidly without filling in the witness grid one by one.

This is because the reading is performed by sampling each filled grid, and this will be explained in detail later.

Further, the horizontal line of the function mark entry field 1f is on the same line as the horizontal line of the knitting pattern entry field 1p.

In addition, the vertical lines are parallel to the vertical lines in the knitting pattern entry field 1p, and the rows (vertical arrangement) of the witness grid in the function mark entry field 1f are arranged on the same line as those in the knitting pattern entry field 1p. Although there are the same number, the number of columns (horizontal arrangement) is 4, for example, compared to 36 in the knitting pattern entry field 1p.

The function mark entry field 1f is used to mark (for example, fill in black) any witness grid when a certain function operation is to be performed. The leftmost column of the vertical row is for programming the forward feeding of the card 1, and the column to the right is for programming the reverse feeding of the card 1. The other two columns are for programming necessary functional operations other than card feeding, such as thread exchange and starting and ending needle selection operations.

Furthermore, in this example, each of the feed control marks 34 displayed in advance on the left edge is positioned on the extension line of the horizontal center line of each stage of the witness grid in the knitting pattern entry field 1P. As will be described later, the card 1 is automatically advanced to each stage of the witness grid.

Furthermore, in addition to the three types of displays mentioned above, the card 1 also has a selection unit number setting field 1S for programming the number of needle selection units in the same color below the knitting pattern entry field 1p. It is displayed in advance.

In this setting field 1S, a required number of independent rectangular witness grids 35 are arranged at regular intervals in the horizontal direction.
It is displayed in columns, and each grid is unique for setting a fixed number of needle selection units, and the number of units set is different from each other, and The set number of units increases in a predetermined base number, and a number representing the number of needle selection units is displayed in advance in the same color below each witness grid 35.

In this example, the number of witness grids 35 is 6 in total, and the one on the left is the number of needle selection units 6, and the following is 12 in hexadecimal.
．． 18°24.30.36.

This needle selection unit number setting field 1S is also scanned by the scanning sensor C of the scanning member, and depends on which witness grid among the witness grids 35 is to be marked. The number of needle selection units is determined.

For example, when knitting a unit pattern using 12 knitting needles, the witness grid 35 labeled 12 is filled in black.

Further, a search mark 36 is displayed on the card 1 in advance so that only the setting field 1S can be effectively read in the electrical signal processing process after reading by the scanning sensor C, as will be described later.

This mark 36 is constituted by, for example, a horizontally long black band with the same vertical width as the witness grid 35 in the setting field 1S, and its position on the card 1 is determined by the column setting of the entry grid 35. On the direction extension line and the feed control mark 34...
..., but its width is longer to the right than that of the feed control mark 34..., and it is located directly below the feed control mark 34... and the knitting pattern entry field 1p. The length includes the width of the blank space.

Then, when the card 1 is loaded on the left and right sprocket belts 81, 8r as described above and the scanning member is in its original position (left stroke end),
A predetermined position within the length range of the feed control mark 34 is read by a scanning sensor C, and the scanning member is automatically transported according to the feed control mark 34 only when it is in its original position. Card 1 is also in the inverted position (with the scanning member
When the stroke end on the right side is reached, the grid row on the right side of the function mark entry field 1f can be read, and the range between these two reading positions can be read while the scanning member is traveling. It is designed to be used.

Therefore, before starting the knitting operation, the card 1 scans the needle selection unit number setting column 1S using the scanning sensor C of the scanning member, and then repeats the automatic step-by-step feeding with the knitting operation. The knitting pattern entry field 1p and the function mark entry field 1f are scanned for each stage by the same scanning sensor C, and such scanning is performed by the forward and backward strokes of the scanning member as described above. However, as will be described later, only the electric signals associated with the forward (rightward) stroke of the scanning member are effectively extracted from the electrical signals associated with the scanning of both the forward and backward strokes.

By the way, as mentioned above, in the knitting pattern entry column 1p,
The knitting pattern representing the unit pattern to be knitted is drawn solidly, and the scanning sensor C of the scanning member scans the knitting pattern horizontally and linearly for each row of drawn grids. The electrical signal related to step scanning is the first
As shown in Figure 2 ■ (an example when card 1 is scanned along the p2-p2 line in the same figure), the shape of the knitting pattern in one row of entry grids, that is, the square shape corresponding to one horizontal scanning mode of the knitting pattern. The electric signal obtained by scanning does not have a one-to-one correspondence with the knitting needle to be selected, and the function mark entered in the function mark entry field 1f does not correspond to the knitting needle to be selected in a one-to-one relationship. The knitting pattern is also read by the scanning sensor C and becomes an electrical signal in the same electrical system as the knitting pattern, and the search mark 36 that is displayed in advance is also read in the same way. Although they are electrical signals in the same electrical system, these three types of electrical signals are separated from each other, and the electrical signals related to reading the knitting pattern are converted into digital electrical signals that correspond to the knitting needles on a one-to-one basis. In addition, the electrical signals related to reading the function marks and the electrical signals related to reading the function marks are separated for each grid row (vertical row) in the function mark entry field 1f. The mechanical structure of the sampling mechanism that performs the operation, that is, the sampling operation, will be explained with reference to FIGS. 3 and 4.

The frame 7 is located behind the running body 29 of the scanning member.
The horizontally long plate-shaped linear encoder 37 is connected to the guide rod 27.
．． It is horizontally mounted parallel to 28.

In order to sample only the search mark 36 on the card 1, the linear encoder 37 is moved to a position corresponding to a blank space between the feed control mark 34... and the knitting pattern entry field 1p on the card 1. 1 search mark sampling slot) 38 S
At the same time, on the right side thereof, a predetermined number (120 in this example) of knitting pattern sampling slits are provided for sampling the knitting pattern drawn in the knitting pattern entry field 1p. ... are arranged in a line from the position corresponding to the left edge of the knitting pattern entry field 1p to the right edge at regular intervals in a straight line to a predetermined position beyond the right edge of the entry field 1p. , and further to the right thereof, a predetermined number (four in this example) of function mark sampling slits 38f for sampling function marks...
... are drilled in one-to-one correspondence with each of the grid rows in the function mark entry field 1f.

On the other hand, on the rear side of the scanning member running body 29, there is a charging sensor, that is, a linear encoder 3, for optically reading the three types of slits 38S, 38p, and 38f.
A sampling sensor d consisting of a light emitter that illuminates the front surface of the sensor 7 and a light receiving element that receives the reflected light is attached.

As the scanning member moves, the sampling sensor d is slit) 388, 38p..., 38f.
It outputs a pulse, that is, a sampling pulse according to..., and the sampling pulse is the same as the electric signal related to the scanning of the scanning sensor C mentioned above, and the sampling pulse is the reciprocating pulse of the scanning member as described later. Of the two strokes, only those related to the forward stroke are taken out as valid ones as shown in FIG. 1 sampling pulse for sampling the knitting pattern, 120 sampling pulses for sampling the knitting pattern, and 4 sampling pulses for sampling the function mark are separated from each other.

By the way, when sampling the knitting pattern, the number of rows (horizontal arrangement) of the witness grid in the knitting pattern entry field 1p was set to 36 to obtain 120 sampling pulses by using 120 slits (38p) for that purpose. In addition to the above-mentioned card 1, as described later, the above-mentioned number of columns is 1.
This is to make it possible to apply the 20 cards (Fig. 19) as well.

Therefore, for card 1 with the number of columns 36, the slit 38 with one entry grid in the knitting pattern entry field 1p
Since three p's correspond to each other, three sampling pulses are changed for each scan of one grid.
In organizing this, two of the three sampling pulses are removed and the electrical signal related to the scanning of one grating is sampled by the remaining one sampling pulse, as shown in FIG. 12W. It looks like this.

In this way, the electrical signal related to one stage scanning of the knitting pattern entry field 1p is sampled for each witness grid, and
As shown in Kunitachi, each bit corresponds to each witness grid, and therefore one knitting needle, and is converted into a digital electrical signal that determines whether it is 1 or O depending on whether each witness grid has a mark or not. The digital electrical signals are sequentially stored in a predetermined memory from left to right, as will be described later.

Then, the stored digital electrical signals are sequentially and repeatedly read out in accordance with the traveling timing of the carriage Y.
It is supplied to one of the pair of left and right knitting needle selection mechanisms (the configuration of which will be explained later) provided on the back side of the carriage Y, which is to be operated effectively.

The reading device A is mechanically configured as described above.

Next, we will discuss the mechanical configuration of the carriage Y side in Sections 4.7 to 4.
This will be explained with reference to FIG.

As mentioned above, the main hand knitting machine automatically starts running the scanning member by reversing the left and right running of the carriage Y.
In order to do this, it is necessary to automatically detect the reversal of left and right running of the Canon Y, and effective scanning of the knitting pattern by the scanning sensor C of the scanning member is performed only in the forward stroke, and the digital electric signal related to that scanning is required. In contrast to storing once in memory sequentially from left to right,
The actual needle selection operation, which is performed by reading out the digital electric signal stored in the memory, is performed during both the reciprocating strokes of the carriage Y, with the left and right knitting needle selection mechanisms operating alternately according to the traveling direction of the carriage Y. In order to knit the knitting pattern according to the knitting pattern drawn on card 1, it is necessary to detect the running direction of the carriage Y and use the detected signal to control the storage and reading of digital electrical signals in the memory. No.

Therefore, the carriage Y is designed as shown in Fig. 7 (the right half of the carriage Y shows the top surface of the base plate with the top cover removed, and the left half shows the back surface) and Fig. 9. It is equipped with a carriage reversing switch mechanism E at the center of the rear side edge, and this will be explained first.

A horizontally rectangular sheath frame 39 is fixed on the base plate 4 of the carriage Y, and a switch actuator 40 is fitted therein so as to be able to slide back and forth within a predetermined length range from side to side.

The switch actuator 40 is made into a single plate-like unit by sandwiching a connecting piece 41 having a T-shaped cross section and a magnet piece 42 that slide on the upper surface of the sheath frame 39 between two front and rear magnetic plates 43□, 43□. The two magnetic plates 43□, 43□
The lower end of the horizontally elongated hole 4' provided in the base plate 4 and the base plate 4
The slide pipe 44 is fixed to the magnetic plate 43. ．． The lower end surface of 43□ is always attracted to a carriage guide bar 45 made of a magnetic material and placed horizontally on the needle bed X.

On the other hand, a microswitch e having three switch parts e1 to e3 is fixedly installed on the rear side of the shaft frame 39, and a lever e' of the switch e is installed on the rear wall of the shaft frame 39. The hole 4 of the magnetic plate 43□ on the rear side passes through the window hole 39'.
3'.

Thus, the switch actuator 40 is fitted into the shaft frame 39 so as to be able to slide freely within a predetermined range on the left and right, and is attracted to the carriage guide bar 45, thereby allowing the carriage Y to move freely. When moving the carriage Y to the left, it slides to the right sliding limit position against the shaft frame 39 and then moves with it, and when moving the carriage Y to the right, contrary to the above, it slides to the left sliding limit position. After being moved, the lever e' of the microswitch e is switched to the left or right by the left/right switching operation of the switch actuator 40, and the switch e operates to move one of the microswitches, that is, the carriage. From the switch part e1 for detecting the running direction, Fig. 15 ■ or Fig. 17
As shown in FIG. II, the binary electric signal is changed from H to L or vice versa by reversing the running of the carriage Y.

Next, the left and right knitting needle selection mechanisms Fl and Fr, which ultimately perform the front and rear selection of the knitting needles N, will be explained with reference to Fig. 4.7.8. However, they have essentially the same structure.

The electromagnet 46 is installed on the carriage base plate 4, and
The upper and lower magnetic poles each have a single piece integrally molded with magnetic material.
One ends of the pair of magnetic conductors 47 and 48 are joined from above and below, respectively, so that different magnetic poles are excited in both magnetic conductors 47 and 48.

On the other hand, a bat guide 49 made of a non-magnetic material is fixed to the lower surface of the carriage base plate 4.

This pad guide body 49 has a left and right long bat passage 491 formed on its lower surface, and in the bat passage 49,
The butt N' of the knitting needle N set at the needle selection receiving position can be received through the side cam 50.

The width of the bat N' is the same in the front and back of this bat passage 491, and its upper wall surface is tapered so that the outer half 49□ on the outside as seen from the carriage Y descends inward, as shown in FIG. Inner half 493 is bat N
The horizontal plane is slightly lower than the steady height of ′.

Therefore, in the process of passing through this bat passage 49□, the bat N' is pushed toward the leaf spring 5 from the middle of the outer half 49□.
1 (Fig. 4) and is gradually pushed down, and the inner half 4
93, and passes through the bat passage 49□ in a tightly fitted state.

In the bat guide 49 having such a structure, the one magnetic conductive body 47 has the outer end of the horizontal portion below the carriage base plate 4 embedded in the thickness of the bat guide 49 from the front side. , a part thereof faces the inner end of the bat passage 49, and the lower surface of the horizontal part faces the inner end of the bat passage 49.
The surface is flush with the inner half 493 of the upper wall surface and continues therefrom.

Further, the other magnetic conductor 48 has a notch 48 □ extending halfway from the upper side in a vertical portion below the carriage base plate 4, and an outer vertical portion 482 on the outside of the notch 48 □ is provided with the electromagnetic magnet. Although the magnetism from 46 acts, it hardly acts on the inner vertical part 483 on the inside.

The magnetic conductor 48 is arranged so that its outer vertical portion 48 □ is along the rear wall surface of the bat passage 49 .
The vertical front surface from the outer vertical part 48□ to the inner vertical part 483 faces inward from the inner end (bat outlet) of the bat passage 49□, as shown in FIG. The surface is inclined to .

In addition, the width t is slightly shorter than the arrangement pitch of the knitting needles N on the right and left sides of the outer vertical part 48□ of the magnetic conductor 48, and the batt N' passing through the batt passage 49□ is in the middle of this t-height, the outer vertical part. The rear surface is brought into pressure contact with the vertical front surface of the magnetic conductor 482, and the head end is brought into pressure contact with the horizontal lower surface of the other magnetic conductor 47, and the front surface of the inner vertical part 483 of the magnetic conductor 48 and the horizontal portion of the magnetic conductor 47 are A rearwardly inclined gap passage 51 (FIG. 7) is formed between the rear end edge and the batt N'.

Therefore, the knitting needles N whose batts N' are fitted into the batt passages 49□ are selected in the following manner.

The bat N' that has entered the bat passage 49 is gradually pushed down with its back and forth movement restrained as the carriage Y travels, and its head end is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47. The rear surface is brought into pressure contact with the vertical front surface of the other magnetic conductor 48 while passing through the magnetic conductor 48 .

If the electromagnet 46 is in an excited state while the carriage Y is traveling for 1 pitch of the knitting needle during this t-yaman, the magnetic conductor 47
By exciting different magnetic poles in the outer vertical part 48□ of the magnetic conductor 48, a kind of magnetic path is formed between them via the butt N', and the outer vertical part 48□ of the magnetic conductor 48 is excited. Because of the rearward inclination, the butt N' is slightly attracted and biased rearward along its outer vertical portion 48 □ and is deviated from the horizontal lower surface of the magnetic conductor 47 into the gap passage 51 .
It immediately rises to a normal height on the rear side of the horizontal portion of the magnetic conductor 47.

The butt N' that has entered this gap passage 51 extends from the rising part of the magnetic conductor 47 on the carriage base plate 4 and the inner vertical part 48□ of the magnetic conductor 48 (the part that is not subjected to the magnetic action of the electromagnet 46). By arranging the magnet piece 52 between it and the rising part, it is further suctioned and biased rearward, and continues to pass through a rearward guide path formed by a group of cams arranged on the back surface of the carriage Y. .

On the other hand, when the electromagnet 46 is in a non-energized state, the bat N' is not attracted to the outer vertical portion 482 of the magnetic conductor 48, and after passing through the bat passage 49□ while being pushed down by the horizontal portion of the magnetic conductor 47. The beam also travels straight, rises to a steady height beyond the inner edge of the horizontal portion, and then passes through a forward guide path different from that in the case of excitation.

The left and right knitting needle sorting mechanisms Fl and Fr are set to the one that should be effectively operated by switching the electromagnet changeover switch section e2 in the microswitch e of the carriage reversal switch mechanism E according to the traveling direction of the carriage Y. Only the electromagnet 46 (in this example, the one on the front side in the direction of movement of the carriage Y) is supplied with power for the needle selection operation.

The left and right knitting needle sorting mechanisms Fl and Fr have the above-described configuration, and the knitting needle N with the rose l-N' inserted into the butt passage 49 Alternatively, the needles are sorted one by one by Fr, but even the inserted knitting needles N may fall outside the range of the needle selection range setting switch actuating piece 31.3r, which is the left and right point setting means mentioned above. In the case where the electromagnet 46 is in the position, the electromagnet 46 does not receive any excitation command and remains in a non-excited state, so that it is not subjected to the above-mentioned sorting action by the electromagnet 46.
Next, such a configuration will be explained with reference to FIGS. 7 and 9.

The left and right switch activation pieces 3 l and 3 r both form a cam groove 3 □ running left and right on their upper surfaces, and
A plurality of protrusions 3° that fit into the needle groove X2 from above are projected from the front end of the lower surface, and furthermore, a plurality of butt engagement grooves 33 are formed on the front side surface to tightly receive the butts N' of the knitting needles N. Then, by fitting the protrusion 3□ into the rear end of the needle groove However, the shapes of the cam grooves 3□ are symmetrical to each other.

That is, the left switch activation piece 31 is connected to the front and rear cam portions 34, 3. which form the front and rear side walls of the cam groove 31. are arranged in a 1fflP relationship, with the front side on the right and the rear side on the left, whereas the right switch activation piece 3r has the opposite relationship to the above.

On the other hand, on the base plate 4 of the carriage Y, there is a switch mechanism for detecting the needle selection end, which is a pair of left and right point detection means that operate the switch by engaging the switch activation pieces 3 l and 3 r as the carriage Y runs. It is equipped with G1 and Gr.

The left and right switch mechanisms Gl and Gr have substantially the same structure, although the mutual arrangement of component parts is symmetrical.

The crank 53 is connected to the carriage base plate 4 by a pivot 54.
A protrusion 55 is provided on the lower surface of the carriage base plate 4 to project downwardly through the window hole 4'' of the carriage base plate 4, and the other end Place the part on the base plate 4
It is connected to the lever of the microswitch 56 mounted above, and as the carriage Y moves, the protrusion 55 moves into the cam groove 3□ of the left or right switch activation pieces 3l and 3r.
By passing through the inside, the crank 53 rotates and switches the microswitch 56.

That is, the left and right switch mechanisms Gl and Gr microswitches 56 and 56 have corresponding protrusions 55.
．． 55 are both turned on when they are within the interval between the left and right switch activation pieces 31 and 3r, and turned off when they are outside this interval.

The left and right protrusions 55.55 are the sorting points of the left and right knitting needle sorting mechanisms Fl and Fr, that is, they are located on the rear extension line of the width portion, and the left and right switch mechanisms Gl, Gr is switched when the sorting point of the left and right knitting needle sorting mechanisms Fl and Fr approaches the installation position of the switch activation piece 31.3 r on the needle bed X, as shown in Fig. 17 III and IV, respectively. It is designed to output an electric signal that inverts from H to L or vice versa, and both of these switch mechanisms Gl
, Gr, the carriage reversing switch mechanism E
The effective needle selection range indicating switch section e3 of the microswitch e allows only the one on the side where the effective needle selection operation is performed to be taken out.

Therefore, as shown in FIG. 17V, the effective needle selection range indicating switch part e3 is configured to detect the effective needle selection range from when the needle selection end detection switch mechanism Gl or Gr on the side that performs the effective needle selection operation is turned on until it is turned off. In other words, while the needle selection point of the knitting needle selection mechanism Fl or Fr on the front side in the direction of movement of the carriage Y is within the interval between the left and right switch activation pieces 31.3r,
It outputs a signal H indicating the effective needle selection range, and outputs a signal when the interval is outside the above range. During the above H output, the above-mentioned memory that stores the digital electrical signals related to the knitting pattern is The reading is performed, and only during that time the magnet 46 on the side that performs the effective needle selection operation is controlled to be energized or de-energized.

In this way, the memory is read out only within the effective needle selection range determined by the left and right switch activation points 31.3 r, but the readout is performed because the traveling speed of the carriage Y is not constant and varies greatly. Therefore, it must be done in synchronization with the travel timing of the carriage Y.

Therefore, photoelectric sensors H1, Hr are attached to the carriage Y at the rear end of the base plate 4 at positions corresponding to the left and right knitting needle sorting mechanisms Fl, FT, respectively. However, the slits X3, which are arranged in a row in a one-to-one relationship with the needle grooves X2, on the needle bed X and the rising wall X1 at the rear end are used as a kind of linear encoder. As the carriage Y moves, the first
As shown in Figure 7 I, a pulse, that is, a timing pulse, is output in accordance with the traveling timing of the carriage Y, and this timing pulse controls the reading of the aforementioned memory. Sensors H1 and Hr will be referred to as timing pulse generators.

It should be noted that, of the pulses from the left and right timing pulse generators Hl and Hr, only those corresponding to the knitting needle selection mechanism Fl or Fr on the side that performs the effective needle selection operation are taken out as valid by the carriage reversing switch mechanism E. It has become.

The mechanical configuration of the hand knitting machine is as described above, and next, the electrical and electronic configuration will be explained.

First, the card 1 is scanned and fed,
An outline of the configuration of the input function section that stores the read knitting pattern as a digital electric signal in the pattern storage memory MEM will be explained with reference to FIG.

Of the electric signals related to card scanning by the scanning sensor C, only those related to the rightward stroke of the scanning member from the original position, which is the left stroke end, to the reversed position, which is the right stroke end, are valid by the effective scanning data forming circuit C. It is taken out as a card feeding and scanning instruction circuit C5, a needle selection unit number setting circuit NS, a memory control circuit MC, and a function discrimination circuit FS.

The card feeding and scanning instruction circuit C5 is configured to receive an electric signal when the left limit switch 331, which is a scanning member original position detection means, is turned on, and the instruction circuit C5 is inputted to the card feeding and scanning instruction circuit C5. Only when the card 1 is in the position, it is determined whether the electric signal from the effective scanning data forming circuit C is H or L, that is, whether the display on the card 1 is a mark or no mark, and the determination result is The control circuit SC controls the motor drive circuit CD according to the marks and no marks to control the pulse motor a for card feeding. The search mark 36, the feed control mark 34, etc. are activated so that the card 1 is displayed on it.
The data is automatically transferred in intervals of .

Further, the instruction circuit C3 is configured to receive an electric signal representing the effective needle selection range from the effective needle selection range instruction switch section e3, and the instruction circuit C5
When the needle enters the range from outside the effective needle selection range defined by the left and right switch activation pieces 31.3r, an instruction signal for starting the scanning member to travel is input to the control circuit SC. The control circuit SC also includes the right limit switch 33, which is a scanning member reversal position detection means.
An electric signal is input when r is turned on, and the control circuit SC controls the scanning member drive circuit SD, thereby also controlling the drive circuit SD.
The coil 31 of the scanning member is supplied with enough current to allow the scanning member to travel back and forth at once.

On the other hand, among the sampling pulses related to the linear encoder reading of the sampling sensor d, only those related to right row scanning are taken out as valid ones by the effective sampling pulse forming circuit and inputted to the pulse separation circuit PS. The pulse for sampling the search mark 36 above, the pulse for sampling the knitting pattern, and the pulse for sampling the function mark are separated from each other, and
Here, when using the card 1 in which the number of rows of grids in the knitting pattern entry column 1p is 36 as described above, the number of pulses (120 pulses in total) for sampling the knitting pattern is 2 per grid. The remaining pulses are sent to the write address designation circuit WA and the memory control circuit MC, and one pulse for sampling the search mark 36 is sent to the selection unit number setting circuit NS. Furthermore, four pulses for sampling the function mark are respectively input to the function discrimination circuit FS.

The number of needle selection units setting circuit NS samples the electric signal related to the reading of the search mark 36 from the effective scanning data forming circuit C according to the one input pulse, and thereby sets the number of needle selection units. This is an instruction to electrically preset the sampling mode of the mark in column 1S, that is, the number of needle selection units, and the setting circuit N.
S is inputted with the above-mentioned pass/L before thinning out for sampling the above-mentioned knitting pattern from the above-mentioned pulse separator circuit PS, and in which number of pulses it is inputted from the effective scanning data forming circuit C. Depending on whether the electrical signal related to reading the mark in the needle selection unit number setting field 1S is input,
The number of needle selection units programmed in the needle selection unit number setting field 1S is stored using a digital electrical signal, that is, the number of needle selection units is electrically preset.

Then, the needle selection unit number setting circuit NS determines whether or not to thin out the pulses for sampling the knitting pattern and how many pulses to thin out in accordance with the stored number of needle selection units. For example, if the number of needle selection units is between 6 and 3, the pulse separation circuit PS is controlled to thin out the needles by two as described above. receives the instruction to electrically preset the number of needle selection units as described above, controls the card feeding and scanning instruction circuit C3 and the card feeding and scanning control circuit SC, and controls the number of needle selection units in the scanning member. After scanning the setting field 1S once and returning to the original position, the card 1 is automatically transferred until the scanning member reads the lowest mark among the feed control marks 34. It is designed to have the function of

The write address designation circuit WA includes a binary counter that counts the pulses inputted from the pulse separation circuit PS as described above, and sends a parallel binary electrical signal to the memory control circuit MC according to the counting result as a write address designation signal. It is now entered as .

The memory control circuit MC samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C using the pulses from the pulse separation circuit PS as described above, and samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C, and assigns the electrical signal to each knitting needle and each bit corresponding to each other. After converting the digital electrical signal into a digital electrical signal (see FIG. 12), the digital electrical signal is sequentially transferred to a certain fixed address in the memory MEM under the addressing control of the write address designating circuit WA, and furthermore, the carriage traveling direction is detected. An electrical signal corresponding to the carriage traveling direction from the switch section e1 is used to store data in separate storage sections for left-hand scanning and right-hand scanning of the carriage Y, that is, in two separate storage sections. It is designed to be memorized.

The function discrimination circuit FS uses the four pulses inputted from the pulse separation circuit PS as described above to
The electric signal related to function mark scanning from the effective scanning data forming circuit C is entered in the function mark entry field 1f.
Samples are taken for each entered grid row, and the sampling of the two columns on the left side of the entered grid row is inputted to the card feeding and scanning control circuit SC, to which the card 1 is sent either in the forward direction or in the reverse direction. In addition, the sampling related to the two columns on the right side is inputted to the function drive circuit FD, which controls necessary function operations such as thread exchange operation.

Further, the card feeding and scanning instruction circuit C5, the control circuit SC, and the memory control circuit MC operate a manual operation means, that is, a clear button CB provided on the operation panel 2 (FIG. 1) of the control box B. This enables manual control, and by operating the button, the card 1 can be transferred by one step in the direction opposite to the transfer direction before the button operation, and the data currently stored in the memory MEM can be cleared. This is to facilitate re-knitting in case of incorrect knitting.

Further, the card feeding and scanning control circuit SC is controlled by operating another manual operation means, that is, a stop button SB, which is also provided on the control panel 2, and the transfer of the card 1 can be stopped by operating the button. It is possible to do so.

Furthermore, when performing a special organization, by operating the special function button W, which is also provided on the control panel 2, the card feeding and scanning instruction circuit C3 is controlled, and the card feeding and scanning perform special operations. It is now possible to do so.

Next, please refer to Fig. 11.12 for the specific configuration of the effective scanning data forming circuit C1, the effective sampling pulse forming circuit D, the pulse separation circuit PS, the needle selection unit number setting circuit NS, and the function discrimination circuit FS. Explain.

The R-S flip-flop 60 is set by the left limit switch 331, which is a scanning member original position detection means, and is reset by the right limit switch 33r, which is a scanning member reversal position detection means, so that the scanning member original position can be detected. 61C and 61d are opened only during the forward movement from the position to the reversal position, and only during this time the output signal of the scanning sensor C and the output signal of the sampling sensor d are respectively effective scanning. The data forming circuit C1 is outputted from the Antogame 1-61C, 61d as an output signal from the valid sampling pulse type control circuit (see FIGS. 12V, IX, and I).

As shown in FIG. 12 II, the output of the limit switch 33l is L when the scanning member is in the original position, and becomes H when the scanning member moves away from the original position. An R-S flip-flop 62 is set when the scanning member leaves the original position to separate the first pulse from the effective sampling pulse forming circuit (sampling of the retrieval mark 36). It is reset by the falling edge of the pulse of

The Q output of this flip-flop 62 opens the AND gate 63 which receives the pulse from the effective sampling pulse forming circuit. The pulses other than the pulses for sampling the function marks 36, that is, the pulses for sampling the knitting pattern and the pulses for sampling the function marks, are output.

On the other hand, the Q output of the flip-flop 62 is added to the AND 64, which is the Q output of the flip-flop 62.
When the output, the output of the effective scanning data forming circuit C, and the output of the effective sampling pulse forming circuit are both H,
That is, the scanning sensor C scans across the search mark 36 on the card 1 and the needle selection unit number setting field 1S (
When scanning is performed along a line (p1p in FIG. 12, V in the same figure is the output waveform of the effective scanning data forming circuit C at that time), the sampling sensor d is connected to the linear encoder 3.
When the No. 7 search mark sampling slit 38S is detected, one pulse is output as shown by vI.

Therefore, this pulse output from AND64 is
This indicates that the search mark 36 has been detected.

The output of this AND 64 (actually, the output obtained by inverting it at knot 64') causes an R-S flip-flop 65 to memorize that the search mark 36 has been detected.
is now set.

This flip-flop 65 is reset by the output of AND66.

The AND 66 receives the Q output of the flip-flop 62, the output of the effective scanning data forming circuit C, and the output of the effective sampling pulse forming circuit. III, IV, V in the figure.

As is clear from Vll, when all the values are H, that is, when the mark placed in the needle selection unit number setting field 1S is detected after the search mark 36 is detected as described above. As shown in (2), one pulse is output, and the flip-flop 65 is reset by this pulse.

Therefore, the flip-flop 65 stores the fact that the search mark 36 has been detected as shown in Vll only until the mark in the needle selection unit number setting column 1S is detected.

In addition, the above-mentioned one pulse also controls the above-mentioned card feeding and scanning instruction circuit CS and the same control circuit SC as described later.

On the other hand, as described above, the pulse IV from the AND gate 63 from which the pulse for sampling the search mark 36 has been removed is sent to a hexadecimal-binary counter 67, specifically, a hexadecimal counter that directly counts the pulse IV. Counting is performed by a counter consisting of a binary counter that converts the count value of the hexadecimal counter into a binary number, and the count value of the counter 67 increments by one every time six pulses IV are counted.

The count value of this counter 67 is the output of the AND 66 above
When the mark in the selected needle unit number setting field IS is detected by the gate network 68 which uses the signal as a gate operation signal, it is written into the memory 69 for storing the number of selected needle units, and is subsequently stored in the memory 69. ing.

This memory 69 stores the output Vl of the flip-flop 65.
It is designed to be reset when l rises, that is, when the search mark 36 is sampled.

Further, the count output of the counter 67 is
Whether the number of pulse IVs from 3 is within 120 or 121
The signal is input to a gate network 70 which discriminates whether the signal is above or below.

This gate network 70 performs the above discrimination on the parallel outputs from the counter 67 using a logic circuit formed by a combination of gates, and if it is within the above 120, an output is generated from the output terminal 1 as shown by Open gate 71□,
If it is 121 or more, an output is generated from the output terminal 2 and the AND gate 71 is output.

It is designed to open.

Therefore, the AND gate 71□ outputs 120 pulses for sampling the knitting pattern as shown in X, and the AND gate 71□ outputs 4 pulses for sampling the function mark as shown in M. A pulse will be output.

The 120 pulses from the AND gate 71□ are input to a pulse selection circuit 72, where they are divided into three types of pulses.

That is, the pulse selection circuit 72 has one output system as ■
As shown in , the above 120 pulses are passed through as is, and the second output system includes a T-type flip-flop and an AND gate connected to this output side, as shown in . Out of the 120 pulses, even-numbered pulses are thinned out and the remainder is output. Furthermore, the output system of 3 includes a ternary counter and an AND gate connected to this output side. As shown in the figure, the 3n-1 (where n is an integer) pulse is left out of the 120 pulses, and the others are thinned out.

On the other hand, the output of the memory 69 which stores the number of needle selection units programmed in the number of needle selection units setting field 1S in the card 1 as described above is the same as the above three types output from the pulse selection circuit 72. Gate network 73 for selecting which of the pulses is actually used as a sampling pulse
If the number of needle selection units is between 6 and 36, an output is generated from the output system 3 of the gate network 73, the AND gate 743 is opened, and the W pulse among the three types of pulses is OR. 75, and 42 to 60.
If it is between ``, an output is generated from the output system of 2, AND gate 74□ is opened, and the pulse of W passes through the OR 75, and if it is between 66 and 120, the output system of l is output. An output is generated, the AND gate 74 is opened, and the pulse (3) passes through the OR gate 75.

In this way, the sampling pulses for sampling the knitting pattern are divided into three types, and the pulses are selectively extracted depending on the number of needle selection units. The number of my lattice rows in the knitting pattern entry field 1p is 36, and the number of needle selection units is 6.12.18, 24, 3.
In addition to cards that can be selected as 0.36, as shown in FIG.
48, 54, 60 cards, and as shown in Figure 19, the number of grid rows is 120 and the number of needle units is 66.
．． 72, 78, 84, 90, 96, 102°108.
This is because a total of three cards, which can be selected as 114 and 120, are used depending on the number of needle selection units.

Incidentally, when using the card 1 shown in FIG. 3, the total number of pulses output from the OR 75 is 4 as shown in FIG.
0 pulses, which are input to the memory control circuit MC and the write addressing circuit WA explained in FIG. In the figure, the output when card 1 is scanned along the p2-p2 line is shown in ■, and the output related to scanning of the knitting pattern entry field 1p is one-to-one with the knitting needle as shown in Megumi. After being converted into a corresponding digital electrical signal, the write address designation circuit WA shown in ■
By the addressing operation of , the information is sequentially stored at a certain fixed address in the memory MEM.

The digital electrical signals are stored in the memo IJMEM for all of the input grids in the first row of the knitting pattern entry field 1p from the left edge to the right edge as described above, but their readout is performed only when the selection is made. This is repeated by the needle selection unit number setting device according to the present invention only for the number of selected needle units set in the number of needle unit setting field 1S, and in order to do this, the number of needle selection units set above is memorized. The hexadecimal-binary output of the memory 69 for storing the number of needle selection units is converted into a binary number by a code converter 76 and is input to a read address designation circuit RA, which will be described later.

Also, the binary output of the code converter 76 is the code converter 7
6', the code is decoded, and the above-mentioned needle selection unit number display means B provided on the control panel 2 reads the code in the memory 6'.
9, the number of needle selection units stored in memory is displayed.

That is, the decoder 76' has 6, 12, 18.24.
...Light emitting element b corresponding to each numerical value of 120...
...is connected.

As shown in FIG. 2, these light emitting elements b are arranged at regular intervals in the length direction of the card insertion slot 9' under the transparent plate 25. Furthermore, on the transparent plate 25, numbers 6, 12, 18.24, . The light emitting elements corresponding to the number of units are lit.

In this way, when the scanning sensor C scans the selection unit number setting field 1S on the card 1, the main hand knitting machine presets the number of needle selection units to the value determined by marking in the setting field 1S. At the same time, the preset number of needle selection units will be continuously displayed from now on by the lighting instruction of the light emitting element.

On the other hand, the four pulses ■ for function mark sampling output from the AND gate 71□ are as follows:
They are separated from each other by a pulse discrimination circuit 77 composed of a group of gates.

That is, the above four pulses are counted by the counter 78, and the coder 79 thereby generates outputs from the output systems 1 to 4, respectively, as shown in M and The gates in the pulse discriminator circuit 77 are opened, so that the output systems 1 to 4 of the pulse discrimination circuit 77 sequentially generate outputs in accordance with the order of the pulses as shown in xxt.

The four pulses separated by the pulse discrimination circuit 77 are input to a function storage circuit 80 composed of a D-type flip-flop, etc., where the sampling of the output (2) from the effective scanning data forming circuit C is This is performed for each entry grid row in the function mark entry field 1f, and the sampled data is stored separately for each entry grid row as shown by the arrow.

4 of 1 to 4 of this function storage circuit 80
Outputs 1 and 2 of the two output systems are input to the aforementioned card feeding and scanning control circuit SC, which will be explained in detail later, and output 1 controls the forward feeding of card 1. The output of 2 is designed to control reverse direction feed,
Further, outputs 3 and 4 are inputted to the aforementioned function drive circuit FD to respectively control required function operations other than card feeding.

Next, the card feeding and scanning instruction circuit C5 and the same control circuit S
The specific configuration of C will be explained with reference to FIGS. 13 to 15.

The above-mentioned clear button CB is used not only in case of incorrect organization as mentioned above, but also as a kind of start button to start the organization when starting the organization using card 1. Before explaining the operations caused by this, an outline of how to use the hand knitting machine will be explained.

First, operate the carriage in the usual manner to perform the necessary knitting such as waste knitting, and when the knitting is completed to the point where the pattern is to be added, the carriage Y is set on the left and right of the knitting needle group set at the needle selection receiving position on the needle bed It is stopped outside one of the ends.

In this state, the card 1 is fed manually, that is, by manually rotating the finger shaft 14 on the control panel 2, and the scanning member is moved so that the upper and lower intermediate portions of the search marks 36 are in their original positions. Set it opposite scanning sensor C.

Afterwards, press the clear button CB above to clear card 1.
is transferred by one pitch in the forward or reverse direction (the direction at this time is not determined as will be explained later), and then the scanning member travels along, for example, the line pl-p1 shown in FIG. After the number of needle selection units is set as described above during the forward movement, forward transport of the card 1 is restarted upon completion of the backward movement.

This transfer continues intermittently until the lowermost feed control mark 34 is detected by the scanning sensor C. Upon this detection, the scanning member immediately moves to line p2-p2 in FIG. Travel back and forth along the
Upon returning to the original position, the series of operations by operating the clear button CB ends.

After this, perform the work necessary for pattern knitting, such as inserting the desired colored thread into the thread opening of the carriage Y, and then move the carriage Y to the left and right switch activation pieces 31.3 r installed on the needle bed X. If the card 1 is repeatedly run back and forth until it exceeds 100, the card 1 can be fed step by step and knit the knitting pattern exactly as drawn on it.

Now, when you operate the clear button CB, the corresponding signal (■ in Figure 14) will be reversed at knot 81 and OR 82.
After passing through the node 81', it is reversed again at knot 81' and output as a card feeding and scanning instruction signal from the card feeding and scanning instruction circuit C3, which is then passed through the card feeding and scanning instruction R-S flip-flop 83 in the control circuit SC and the scanning signal. An R-S flip-flop 84 for instructing forward movement of the member is set.

The flip-flop force III passes through the AND gate 85 and opens the AND gate 86 as shown in ■.
A pulse from the timer 87 is applied to the motor drive circuit CD through the motor drive circuit CD to drive it, and the pulse motor a for card feeding is rotated forward or reverse, so that the card 1 is moved in the forward or reverse direction. It is now ready to be transported.

This transfer is performed by the search mark 3 on card 1 as described above.
When the upper and lower intermediate portions of the scanning member 6 are opposed to the scanning sensor C of the scanning member, scanning is performed by a predetermined one pitch.

That is, the output pulse from the timer 87 that determines the feed amount for l pitches of the card 1 is sent to the D-type flip-flop 88.
It is input to the 0T terminal, and due to the rising edge of the Q output IV of this flip-flop 88, the above-mentioned flip-flop 8
3 is set to be reset.

Further, the output of the effective scanning data forming circuit C is input to the D terminal of the above-mentioned flip-flop 88, and the flip-flop is connected to the right limit switch which is the scanning member reversal position detecting means. 33
Further, the timer 87 includes an oscillator such as an unstable multivibrator and a binary counter that counts the oscillation signal, and the output of the counter is It is designed to be finally output as a pulse with a predetermined time width, and its counter is connected to the flip-flop 8.
It is designed to be reset by the L output III of No.3.

The D-type flip-flop 88 is designed to sample and output the input from the D terminal using the rising edge of the input pulse from the T terminal, and the timer 87 is activated by operating the clear button CB as described above. When the card 1 is sent by l pitches, the search mark 36 still does not cross the scanning line of the scanning sensor C either above or below, so the D terminal of the flip-flop 88 is output. , an H output indicating that a mark has been detected is inputted by the effective scanning data forming circuit C, and the flip-flop 83 is reset by the output of the flip-flop 88.

Therefore, when the timer 87 outputs just one pulse, it stops operating and the AND gate 86 closes.
Card 1 is only sent l pitches.

By the way, when the clear button CB is operated, the R-S flip-flop 89 is set, and the feed direction inversion circuit 90 is controlled by its output for the set time, that is, until it is reset by the right limit switch 33r. This is to change the output operation of the motor drive circuit CD, so that the card 1 is transferred in the opposite direction. However, when the clear button CB is operated in the above state, the card 1 is transferred in the opposite direction. R-S flip-flop 91 for instructing the feed direction of 1
Since it has not been determined whether it is in the set state or in the set state, it has not been determined in which direction the one pitch will be transferred.

When this one-pitch transfer is completed, the scanning member moves forward.

That is, when the clear button CB is operated, the scanning member forward movement instruction flip-flop 84 is set as described above, and its Q output is input to the AND 92. Since a signal obtained by inverting the Q output of the flip-flop 83 by the nost 93 is input, when the flip-flop 83 is being set, that is, when the card 1 is being transferred, the output of the AND 92 is the same as the above-mentioned scanning member drive rotation. The scanning member is not moved forward by driving the SD, but is moved forward only when the card 1 is stopped.

This forward movement ends when the flip-flop 84 is reset by the right limit switch 33r, as shown in FIG. The scanning member immediately begins to move back.

This backward movement is caused by the limit switch 33 on the left side of the scanning member.
However, since the scanning member collides with the limit switch 331 at a considerable speed, the reaction causes the limit switch 331 to be turned on.
31 may chattering as shown in FIG.
The original position return signal is delayed as shown in FIG. 115X and resets the flip-flop 94 as shown in FIG. Even after reaching this point, it is possible to apply a force that causes it to move further to the left, thereby preventing the above-mentioned fear from occurring.

As described above, when the scanning member moves back and forth by operating the rear button CB, during the forward movement, the needle selection unit number setting circuit NS is activated in the needle selection unit number setting field 1S as described above.
The electrical setting of the number of needle selection holes programmed in is performed, and when the setting is done, one pulse is sent from the needle selection unit number setting circuit NS (for details, refer to the note in it 64'). (Fig. 14), the R-S flip-flop 96 in the card feed and scanning instruction circuit C5 is set, and its Q output (Fig. 14 -) is the OR 82, NOT 8
2', the card feeding flip-flop 83 is set again, but the AND gate 86
The card 1 is configured so that the signal from the limit switch 331 on the left side can be input through the knot 97, and opens only when the scanning member is in the original position. It will not be transferred while the scanning member is running after setting the number of needle units.

When the scanning member returns to its original position, the flip-flop 8
3 has already been set as described above, the pulse of the timer 87 is inputted to the motor drive circuit CD through the AND gate 86 as shown in (2), and the card 1 is transferred.

At this time, the transfer direction is determined by the needle selection unit number setting circuit NS.
) sets the flip-flop 91 which instructs the card feeding direction via the OR 98, and the flip-flop 89 which was set by operating the clear button CB is set by the right limit switch 33.
Since it is reset by r, the Q output of the flip-flop 91 is directly applied to the motor drive circuit CD through the feed direction reversing circuit 90, so it is in the forward direction.

The feed direction reversing circuit 90 is composed of two exclusive OR circuits, and the flip-flop inputs the input from the flip-flop 91 directly to the motor drive circuit CD, and conversely, when the output is H, the input is input to the motor drive circuit CD. Furthermore, the flip-flop 91 instructs forward feeding of the card 1 when its Q output becomes H at the time of setting, and when its Q output becomes H at the time of reset. It is designed to instruct reverse direction feeding.

The card 1 is first transferred one pitch, but at that time the scanning sensor C is still detecting the search mark 36, so the output IV of the D-type flip-flop 88 is used to transfer the card. Flip-flop 83 is about to be reset.

However, since this flip-flop 83 is given priority to the set signal, and the flip-flop 96 supplying the set signal is activated by the subsequent detection of the search mark 36, the output Since it is not reset by the output of the effective scanning data forming circuit C (reset by the falling edge), the set state is still maintained, and the card 1 continues to be repeatedly and intermittently transferred in the forward direction.

When the search mark 36 is moved away from the position facing the scanning sensor C due to such forward movement, the flip-flop 96 is reset at that moment and the set signal to the card feeding flip-flop 83 disappears, but the flip-flop 83 is reset. input to the D terminal of the D-type flip-flop 88 (effective scanning data forming circuit C
output) also corresponds to no mark, so Iv
As shown in the figure, the output of the D-type flip-flop 88 is a flop.

I ended up resetting the flop 83. First, since the flip-flop 83 still maintains the set state, the card 1 continues to be transported in the forward direction even in the no-mark section where the search mark 36 is removed.

When the lowermost one of the feed control marks 34 is detected by the scanning sensor C due to the continuous forward movement, the D-type foot-flop 88 resets the flip-flop 83.
Transfer of card 1 is stopped.

At the same time, as described above, by operating the clear button CB, the Q output line of the scanning member forward movement flip-flop 84, which is in the set state, is changed to the flip-flop 8.
3 reset, the scanning member drive circuit SD is input via the AND 92, so that the scanning member reciprocates and the scanning sensor C moves the card 1 to the first position.
The scanning member scans along the line p2-p2 in Figure 2, and stops when it returns to its original position, thereby completing the above-described series of operations performed by operating the clear button CB.

The digital electrical signal (yyi in Fig. 12) representing the knitting pattern obtained by the first one-stage scanning is as follows:
To that extent, it is possible to simultaneously write to both of the two storage sections of the memory MEM.

The first scanning of the knitting pattern entry field 1p and function mark entry field 1f of card 1 is automatically performed by operating the clear button CB as described above, but subsequent scanning is performed automatically by operating the clear button CB. This is automatically performed for each stage by reciprocating the carriage Y, which will be explained next.

When the carriage Y is reversed, the carriage traveling direction detection switch part e in the carriage reversal switch mechanism E is activated.
1 (Fig. 15 ■) is inverted from H to L or vice versa. This inversion is detected by the carriage reversal detection circuit 100, which includes a knot, two differentiating circuits, and a NOR. The signal shown in FIG. 15 II is output, the carriage inversion storage flip-flop 101 is set, and the fact that the carriage Y has been inverted is stored.

When the carriage Y enters the effective needle selection range divided by the left and right switch activation pieces 3 1 and 3 r by running after this reversal, the output of the effective needle selection range indicating switch section e3 is activated as described above. As shown in FIG. 15 IV, this output and the Q output I of the flip-flop 101 are
AND 102 inputted with II outputs a signal H as shown in V.
This signal passes through the or 82 and is output to the knot 82.
' After being inverted as shown in VI, the card feeding and scanning instruction signal is output from the card feeding and scanning instruction circuit CS, and the flip-flops 83 and 84 in the control circuit SC are inverted as shown in . It is designed to be set to .

By the way, since the output of the knot 82' is also used as a reset signal for the flip-flop 101, the flip-flop 101 is reset at the moment the output of the knot 82' occurs, and as a result, the AND 102, The output of the knot 92' becomes a trigger waveform as shown at V and VI.

By setting the flip-flop 83, the pulse ■ from the timer 87 is inputted to the motor drive rotation CD through the AND gate 86 as shown in M, as in the case of operating the clear button CB described above, and the first pulse ■ Therefore, the feed control mark 34 is first sent in the forward direction by one pitch, but because the feed control mark 34 misses the scanning sensor C by this one pitch movement, the output ■ of the effective scanning data forming circuit C corresponds to a no mark. As a result, the above-mentioned flip-flop 88 does not reset the flip-flop 83, and the timer 87
The next pulse is output and the cart 1 is further transported by one pitch.

When the card 1 is transferred in this way and the next feed control mark 34 is detected by the scanning sensor C, the flip-flop 83 is reset and the transfer of the card 1 is stopped. Q output of the flip-flop 84 for instructing forward movement of the scanning member ■
is input to the scanning member drive circuit SD via the AND 92 as shown at W, so the scanning member moves forward immediately after the transfer of the card 1 is stopped, and the limit switch 3 on the right side
3 When r is turned on, the flip-flop 84 is reset by its output W, and instead, the flip-flop 94 for instructing the scanning member to move back is set, so that the scanning member moves back and reaches the original position. At this point, it stops and one stage scanning of card 1 is completed.

Thus, the carriage Y is moved between the left and right switch activation pieces 31.3.
Every time card 1 is moved leftward or rightward from outside the range of r to within the range, card 1 moves to the feed control mark 34...
It is automatically transferred by an interval length of . and is scanned by the scanning sensor C for each stage.

Note that the output (■) of the function storage circuit 80 in the function discrimination circuit FS (output when a mark has been applied to the leftmost grid row among the four grid rows in the function mark entry field 1f) ) is designed to set the flip-flop 91 for instructing the feeding direction via the OR 98, and the output of 2 (a mark is placed on the second entry grid row from the window edge) The output (at time) is reset, and by marking any entry grid in the above two entry grid rows, it is possible to arbitrarily control whether card 1 is sent forward or backward. It is something.

Further, when the stop button SB is operated, the AND gate 86 is closed, so that even if the carriage Y is moved back and forth as described above, the card 1 is not transferred and only the scanning member is moved.

Therefore, when the stop button SB is operated,
The card 1 is repeatedly scanned in the same row, and one aspect of the knitting pattern in that row can be knitted in a repeating and continuous pattern.

Furthermore, the AND 102 generates the output shown in FIG. This is done in the same way even when entering from the right direction, but when button W is operated, the carriage Y is reversed from the left row to the right row and moves into the effective needle selection range from the right side. Only when you enter
Another AND 103 generates an output, and card feeding and scanning are performed only at that time.

Furthermore, the clear button CB functions as a kind of start button when starting the scanning of card 1 as described above, but if it is operated during the scanning stage of the knitting pattern, each time the clear button CB is operated, card 1 is It is possible to transfer only one step in the opposite direction from the previous step,
This is clear from the above.

The input function part described above transfers and scans the card 1, and the knitting pattern drawn in the knitting pattern entry field 1p is read one by one row by row and one-on-one with the knitting needles N.
It is designed to be stored in the pattern storage memory MEM as a corresponding digital electrical signal due to the relationship between
Next, the stored digital electrical signal is transferred to this memory MEM.
Fig. 16.17 shows an output function portion that causes the left and right knitting needle selection mechanisms Fl and Fr to select knitting needles N by reading out data in time with the travel timing of the carriage Y while it is traveling within the effective needle selection range. Please refer to the description.

When the carriage Y enters the effective needle selection range and the effective needle selection range indicating switch part e3 of the carriage reversal switch mechanism E outputs the signal H as shown in FIG. Read address designation circuit R only during output
A becomes set.

This read address designation circuit RA includes an up/down counter, and is configured to count timing pulses inputted from the timing pulse generators Hl and Hr each time the carriage Y travels by one pitch of the knitting needles. However, the counted value is based on a parallel binary signal (more specifically, the 11th
By inputting the output of the code converter 76 shown in the figure, the number of needle selection units is preset to the same number as the number of needle selection units (12 in this example) programmed in the number of needle selection units setting field 1S of the card 1. At the same time, the switching of the addition and subtraction is performed by a signal II representing the carriage running direction rather than the carriage running direction detection switch part e1, and the timing pulse is added or subtracted depending on the carriage running direction. It is supposed to be done.

Thus, the read addressing circuit RA
Each time the preset number of timing pulses is counted while the vehicle is running within the effective needle selection range, the same value (parallel binary electrical signal) is repeatedly obtained as shown in (3).

In other words, it can be said that this circuit RA encodes the knitting needles N between the left and right switch activation pieces 31.3r and assigns repeat numbers to them in a certain direction.

Therefore, the output of this circuit RA is supplied to the memory control circuit MC as a read 7 address designation signal (read instruction signal) for the memory MEM, and also as a signal indicating the carriage running direction. ■ is the memory ME to the memory control circuit MC.
The digital weight signal stored in the memory MEM is input as a signal to determine which of the two storage sections of the carriage Y should be read out. In this example, 12 pits from 0 to 11 are read out repeatedly,
As shown by X, the signal is output from the memory control circuit MC as a binary electric signal and input to the waveform processing circuit WP.

The waveform processing circuit WP receives the signal ■ from the effective needle selection range indicating switch section e3, and only during the H period, it supplies the signal from the memory control circuit MC as valid to the electromagnet drive circuit MD. The output of this drive circuit MD is input by the electromagnet changeover switch e2 to the electromagnet 46 of the knitting needle sorting mechanism Fl or Fr, which is the one that performs the effective sorting operation.

In this way, the knitting needles N between the left and right switch activation pieces 31.3r are divided into groups of 12 as shown in
Sorting according to the form of the knitting pattern drawn between the two grids on the right (for example, in Fig. 17, the ellipse shown by the solid line is the forward deviation, the filled-in one is the backward deviation, and the oval shown by the broken line is the backward deviation). (showing the one in the rest position where it is not subjected to needle selection action).

By the way, as mentioned above, the knitting pattern entry column 1p is scanned over the entire length of its left and right ends, and all the bits of the digital electric signal obtained by the one-stage scanning are stored in the memory MEM, and are read out from there. The number of bits is determined by the number of needle selection units programmed by marking the number of needle selection unit setting field 1S. For example, if it is set to 12, even if the left side is Even if a knitting pattern is recorded on the right side of the 12th entry grid, the recorded portion on the right side is scanned and temporarily stored in the memory M.
Although it is stored in the EM, it is not read out as a signal for needle selection.

With the above configuration, it is possible to knit a unit pattern according to the knitting pattern on the card 1, but the main hand knitting machine can also knit the pattern actually knitted without changing the knitting pattern. can be changed by manual operation of the manual operation member on the control panel 2, which will be explained next.

The pattern left/right selection means RL changes its output electric signal to H as shown in FIG. 17 VI by switching its manual operation section.
The signal is inverted from L to L or vice versa as shown in FIG. The addition/subtraction direction of the up/down counter of the read address designating circuit RA is designated by the comparison signal Vll.

Therefore, the count value of the read address designation circuit RA determines whether the carriage Y travels in a certain direction in accordance with the above-mentioned relationship (■) or in the relationship (W).
It is determined based on the operation of L. Even if the knitting pattern on card 1 is the same, the knitted pattern in the case of ■ and W is as if the left and right are reversed. be.

Next, the pattern mode selection means MS outputs an electric signal that changes from L to H or vice versa as shown by X by switching the manual operation section, and supplies it to the waveform processing circuit WP. By the operation of this means MS, the waveform processing circuit WP is controlled by the memory control M.
It is determined whether the input X from C is passed through without being inverted or whether it is inverted as shown in M.

Therefore, by operating this means MS, the front and rear sorting mode of the knitting needles N can be reversed, and thereby the card 1
This allows the ground pattern of the knitted pattern to be reversed without changing the knitting pattern above.

Although one embodiment of the hand knitting machine to which the present invention is applied has been described above, the present invention is not limited to the present invention.

That is, in the above embodiment, a sprocket bell (81.8r) was used as the support for supporting the card 1, but a drum or the like having sprockets formed on both sides of the circumferential surface may also be used.

Further, in the above embodiment, the scanning member is moved after the card 1 is transferred, but it is also possible to move the card 1 after the scanning member is moved. It is.

Further, in the above, the left and right switch activation pieces 31.3r are arranged on the needle bed X as point setting means for dividing the effective needle selection range, while the switch activation pieces 31.3r are placed on the carriage Y as point detection means. 3. It is equipped with mechanical needle selection end detection switch mechanisms Gl and Gr that operate as switches when engaged with r, but as a point setting means, a member with an optical mark is placed on the needle bed X. This may be detected by a photoelectric sensor as a point detection means provided on the carriage Y side, or a reed switch can be slid left and right as a point setting means on a guide rod or the like installed horizontally on the X side of the knitting machine main body. Even if the carriage Y is equipped with a permanent magnet and the reed switch is operated when the carriage Y approaches the reed switch, electrical detection of the left and right ends of the effective needle selection range cannot be performed. It is possible.

Further, in the above embodiment, the coil 31 of the scanning member
is fitted into the guide rod 28, and by passing currents of opposite polarities through it, the permanent magnet 32 is used as a stator to apply magnetic forces in opposite directions to the left and right coils 31, thereby causing the scanning member to reciprocate. However, there are two coils whose winding directions are reversed.
Moreover, even if the guide rod 28 is made of a magnetic material and current is passed through the two coils alternately so that a magnetic force is generated between the coil and the guide rod 28, the scanning member can be moved back and forth. It is something that can be run.

In this case, the guide rod 28 functions as a guide means for guiding the movement of the scanning member, and at the same time functions as a stator of the linear motor.

Furthermore, in the above, a card in which one entry grid corresponds to one stitch was used as the knitting program card 1, but a card in which one entry grid corresponds to a predetermined plurality of stitches may also be used. A card on which a pattern, a function mark, and a needle selection unit number setting mark are printed in advance may be used.

Furthermore, the knitting pattern and the above marks can be created by filling in the card surface, or by pasting colored paper of the desired shape onto the card, and can be read in the same way as above. It is.

Furthermore, in the above, all the bits of the digital electric signal related to one stroke of scanning of the scanning sensor C are temporarily stored in the pattern storage memory MEM, and when reading it out, the bits determined by marking on the card 1 are set. However, on the contrary, the digital electrical signals are selected at the stage before being stored in the memory MEM. Even if the data is stored in the data and all of the data is read out at the time of reading, the same effect as described above can be achieved, and such a configuration is considered to be an embodiment of the present invention.

In addition, to display the number of needle selection units, a light emitting diode,
This may also be done by lighting and displaying the numbers using a number display segment such as a liquid crystal display.

As is clear from the above description, the device for setting the number of needle selection units of the present invention is capable of electronically transmitting information instructing the number of needle selection units recorded on a predetermined information recording medium (knitting machine program card in the embodiment). Reading element that reads as a signal (
By discriminating the electrical signals from the scanning sensor C) and this reading element in the embodiment, a digital electrical signal corresponding to the number of needle selection units set by recording the information on the information recording medium is generated. (a combination of an AND 66, a flip-flop 65, and a hexadecimal-binary counter 67 in the embodiment) and a memory for storing the number of needle selection units that stores the digital electrical signal obtained by this circuit. For the digital electrical signal corresponding to the pattern, only the number of bits corresponding to the numerical value represented by the digital electrical signal stored in the memory for storing the number of needle selection units can be stored in the pattern storage memory, or A circuit (read address designation circuit RA in the embodiment) that enables reading from the memory, and display means that displays the numerical value represented by the digital electric signal stored in the memory for storing the number of needle selection units. This system allows knitting needles to be sorted into groups according to the number of needle selection units programmed on a predetermined recording medium such as a card, thereby determining the number of knitting needle groups involved in knitting one unit pattern. The number can be changed arbitrarily, and the number can be arbitrarily set by recording on the above-mentioned predetermined recording medium, and the current number of needle selection units can be easily known by the display on the display means. It is something that can be done.
