Description

[Detailed description of the invention]

The present invention relates to a hand knitting machine having an electronic configuration, and more particularly, a digital electric signal of a system corresponding to the pattern to be knitted is stored in a storage device, and the digital electric signal is transmitted to the knitting needles in relation to the movement of the carriage.
The present invention relates to a hand knitting machine that reads timing pulses obtained every time a pitch is moved and selects needles according to the contents of the read timing pulses. In order to perform pattern knitting with this type of needle selection device, the digital electrical signals stored in the storage device must be effectively read out only while the carriage is traveling within a required range. Therefore, by detecting the left and right running reversal operation of the carriage IJ with an appropriate detection means and controlling the setting operation of the storage device based on the electric signal related to the detection, the left side of the carriage on the needle bed is It is conceivable that the above-mentioned reading is performed only within the range between the running reversal position on the right side and the running reversal position on the right side, and pattern knitting is performed only within this range. However, if you do this, especially in the case of hand-knitting machines where the carriage often moves left and right in small increments when the carriage is not related to knitting operations, This method also has the disadvantage that misorganization occurs frequently. The present invention does not have such drawbacks, and can accurately perform pattern knitting only within an arbitrary range that has been arbitrarily positioned on the needle bed. The number of needle selection units can be arbitrarily changed without changing the number of needle selection units, and this assumption can be made manually at the rear of the needle bed while viewing the knitting pattern on the knitting pattern recording medium. be. That is, the present invention includes a feeding member that transports a knitting pattern recording medium, a scanning unit that scans the knitting pattern recorded on the knitting pattern recording medium, and a sampling pulse that generates a sampling pulse every time the scanning member moves a certain distance. and a circuit that converts an electrical signal related to the scanning of the scanning member into a digital electrical signal of a predetermined number of bits per scanning stroke by sampling with the sampling pulse. A unit vague knitting needle which is provided behind the needle bed of the machine body and can arbitrarily manually set the number of bits stored in the storage device or the number of bits read from the digital electric signal of the predetermined number of bits. A number setting means is provided in the main body of the striping machine, and a manual operation section of the unit pattern stripe stitch number setting means is arranged on an operation panel installed behind the needle bed of the knitting machine main body, and a pair of effective selectors are provided on the left and right sides. means for installing a needle range indicating means at any position in the longitudinal direction of the needle bed and outputting a predetermined electrical signal when a specific portion of the carriage corresponds to the effective needle selection range indicating means; Controlled by the signal, only when the carriage is traveling between the left and right effective needle selection range indicating means, the digital electric signal stored in the storage device is stored in the bit number set by the unit pattern line stitch number setting means. The invention is characterized in that it includes a readout circuit that sequentially and cyclically reads out the data. An embodiment of the present invention will be described in detail below with reference to the drawings. First, regarding the overall outline of the hand knitting machine to which the present invention is applied,
To explain with reference to FIG. 1 showing the plane, a knitting pattern recording medium, that is, a knitting pattern recording card 1 on which a knitting pattern is drawn, can be loaded into the knitting machine main body X having a needle bed x, and the knitting pattern recorded on it can be loaded. A scanning device A equipped with a scanning unit 2 for optically scanning the image, and manual operating means used to manually operate various mechanisms described below in addition to the scanning device A are mounted on an operation panel 3. A control box B is provided with various electrical and electronic circuits as will be described later, and a pair of left and right cursors 41 serve as effective needle selection range indicating means for dividing the effective needle selection range on the needle bed x.
4r is installed at the rear of the needle bed
(not shown in the figure) A pair of left and right knitting needle sorting mechanisms CI, C in which either one operates effectively forward and backward sorting using electromagnetic force.
r are placed a predetermined length apart on the left and right. The scanning section 2 can move left and right following the movement of the carriage Y, but it can only move within a predetermined left and right limited range, which corresponds to the above-mentioned left and right limited range of the carriage Y. While the card 1 is running for a length of time, the recorded knitting pattern is scanned horizontally in a straight line on the card 1, and an electric signal corresponding to the scan is outputted, and the subsequent processing of the electric signal is performed by an electronic configuration. Furthermore, power is supplied to the electrical components of the pair of bran needle sorting mechanisms CI and Cr through a power collector assembly D that is long on the left and right and is installed on the back of the carriage Y on the x side of the knitting machine body. The more effective sorting action is performed on the needles (in this embodiment, the ones on the front side in the direction of movement of the carriage Y), and the sorting action is performed only on the knitting needles within the interval range of the cursors 41 and 4r (even the needles within this range are sorted). (except for those in the rest position where they are not affected at all). First, the specific configuration of the magazine scanning device A will be explained with reference to FIGS. 2 to 4. A card feeding roller 5 for supporting the knitting pattern recording card 1 in a U-shaped folded state and feeding it in steps by a sprocket wheel is parallel to the needle bed x and is rotatable on a frame 6. It is constructed in Below this roller 5, there are two guide bars 7 at the front and rear.
, , 72 are horizontally strung on the frame 6 in parallel, and the scanning member 2 is mounted on them so that it can slide left and right along them. That is, as shown in FIG.
,, 72, and Tsutomu Numa freely beats the beat. The scanning member 2 has a light detection mechanism (not shown) at its tip (upper end), that is, a light-emitting 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. A built-in pipe-shaped scanner 10 is installed vertically, and the scanner 10 scans the card horizontally in a straight line. To explain card 1 here, it has a knitting pattern entry field 11 and left and right function mark entry fields 112, 113 on its white surface between the left and right perforations 1'. The light emitting element is provided with a light emitting element of the same color as the light emitting element, and the light receiving element does not discriminate the color (for example, red when a red light emitting diode is used as the light emitting element). In the above-mentioned knitting pattern entry column 11, among the above-mentioned grid division lines, the total is the division line between stitches, and the horizontal line is the division line between knitting rows, and the above-mentioned stitches are indicated at key points outside the grid. Numbers and numbers representing the number of knitting stages are displayed in the same color as the grid division lines. More specifically, the knitting pattern entry field 11 is one minimum section (coordinate grid).
corresponds to one stitch, its horizontal arrangement corresponds to one knitting needle, and its vertical arrangement corresponds to a knitting row, and a unit pattern in which n horizontal rows of stitches constitute one group. When composing, use the vertical line on the left and the n on the right.
Regard the vertical line separated by the book as the boundary line, and draw a picture (knitting pattern) corresponding to the unit pattern to be knitted between them on a black background using an appropriate writing instrument, for example, as shown in the illustration. It is something to keep. For example, when knitting a unit pattern with 24 rows of stitches by selecting 24 stitches as a unit of one group, the stitches must be selected within the range between the leftmost vertical line and the 24th vertical line. It is meant to draw a picture. 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 out the minimum divisions one by one. This is because the discussion is performed by sampling each minimum section, and this will be explained in detail later.
The left and right function mark entry fields 112 and 113 are
When attempting to perform a required function operation, the appropriate minimum section is filled in. For example, when the card 1 is fed to a certain point (as will be explained later, the card 1 is automatically transferred one pitch each time the scanning member 2 completes one stroke of scanning), then Depending on the scanning of the needle, needle selection may not be performed in effect, or the card may be automatically reversed from there, or an appropriate alarm may be activated to notify of thread replacement, etc. The smallest section is filled in (for example, black) as a signal filter or function mark. As mentioned above, in the knitting pattern entry field 11 of the card 1, a knitting pattern representing the unit pattern to be knitted is drawn in outline, and the scanning member 2 scans the knitting pattern in the horizontal row of the minimum section. The wire is scanned in a straight line for each row, and the electrical signals from it are as shown in FIG. If this is the only square wave, the electrical signal obtained by scanning will not have a one-to-one correspondence with the knitting needle to be selected, and the function mark entry field 11
2,113 is also read by the scanning member 2 in the same way as the knitting pattern,
These two types of electrical signals are generated in the same electrical system as in that case, and the former is generated by the knitting needle by a sampling pulse obtained from the sampling pulse generation mechanism described below in connection with the scanning of the scanning member 2. and 1
The sampling pulses are converted into corresponding digital electrical signals in a one-to-one relationship, and the latter are extracted separately from the former.Next, the sampling pulse generation mechanism will be explained. A fan-flat through hole 12 is formed between the horizontal through holes 9 and 92 in the running base 8 of the scanning member 2.
A pulse plate (linear encoder) 13 horizontally mounted on the frame 6 is passed through between the guide bars 7, 72. The pulse plate 13, as shown in FIG.
In the rear green groove 14 for sampling the knitting pattern. . . . are arranged in rows, one by one, corresponding to the horizontal arrangement of the minimum section in the knitting pattern entry column 11 of card 1, and in the front green, there are marks for sampling the function marks. Grooves 142, 143...
...in the function mark entry fields 112, 113
One piece is provided corresponding to the horizontal arrangement of the smallest partitions. As the scanning member travels, the groove 14 on the rear side of the pulse plate 13. . . . optically reads the knitting pattern and generates a sampling pulse for sampling the knitting pattern, and the front grooves 142, 143 . It is equipped with a sampling pulse generator a2 for generating sampling pulses for reading and sampling the function marks (FIG. 2). That is, on the upper and lower sides of the through row 2 passing through the pulse plate 13, at positions corresponding to the rear grooves 14, . . . and the front grooves 142, 143, . , light emitting elements 15,,152 and light receiving elements 16,,1
62 are arranged in the hole so as to face each other. Therefore, the sampling pulse generator (more specifically, the light receiving element 16 constituting it) is connected to the scanning of the scanning member 2 as shown in FIG.

As shown in [0], each time the scanning member 2 scans one minimum section in the cardo knitting pattern entry column 112, one pulse is output.
In addition, the sampling pulse generator a2 is configured such that the scanning member 2 is 1 in the function mark entry fields 112 and 113.
One pulse will be output every time the smallest section is scanned. The automatic transfer of the card 1 one pitch at a time is performed as follows. Limit switches 171 are provided on both left and right sides of the frame 6,
17r is provided, and when the left pressing plate 181 of the running platform 8 of the scanning member 2 operates the left limit switch 171, and when the right pressing plate 18r activates the right glue limit switch 17r. , the control box B
An electromagnetic device (not shown) installed inside is operated to rotate the card feed roller 5 by one pitch. In addition, a connecting piece 19 made of magnetic material is provided on the traveling base 8 so as to protrude toward the front side (carriage Y side).The front end head of the connecting piece 19 is located behind the needle bed x of the striped machine body A horizontally long guide groove 20' of the power distribution wall 20, which is erected over almost the entire length of the power distribution wall 20, is fitted with an iron so as to be slidable left and right, and the front surface of the front end head thereof is exposed to the front surface of the power distribution wall 20. On the other hand, the carriage Y has a magnet piece 22 in the center of a horizontally elongated casing 21 made of non-magnetic material attached to the rear side surface, on the same level as the linking piece 19, and a magnetic plate 23 on both its upper and lower surfaces.
,,232 are installed by adsorption. Therefore, while the carriage Y is traveling, the magnetic plates 23, .
232 faces the linking piece 19 and adsorbs it, the scanning member 2 moves integrally with the carriage Y.
′ and the magnetic plates 23, 2
It ends when the adsorption with 32 is removed, and it will not run any further. That is, the scanning member 2 moves integrally with the carriage Y to the left or right only within the length range of the guide groove 20', and is unrelated to the movement of the carriage Y outside that range. The scanning device A has the above-mentioned configuration,
As the carriage Y travels within the guide groove 20', the scanning member 2 scans the card 1, and the knitting pattern on the card 1 is created by sampling with sampling pulses from the sampling pulse generator a, as shown in FIG. ] As shown in FIG. 2, it is obtained as a digital electrical signal in which one minimum section of the knitting pattern entry field 11 corresponds to one bit, and this digital electrical signal is obtained by scanning by the scanning member 2 in the left row. The stored digital electrical signals are stored separately in the storage device MEM (block diagram shown in FIG. 10, details will be described later) for scanning by the right row and scanning by the right row. During the next rightward or leftward operation due to reversal, the one of the pair of cotton needle sorting mechanisms CI, Cr that is effective in sorting functions every time it corresponds to one knitting needle, that is, according to the traveling timing of the carriage Y. One bit is sequentially read out, and depending on the bit content (1 or 0), one striped needle selection mechanism that performs effective selection is controlled to 1 or Cr. Let's explain the parts. First, as the carriage Y travels, timing pulses are generated according to the travel timing, that is, timing pulses for reading digital electrical signals stored in the storage device MEM from the timing pulse generation mechanism.
This will be explained with reference to FIG. The current collector assembly D mentioned above includes two horizontally elongated metal plates 24, 242, upper and lower, which are both conductive and magnetic.
Accordingly, the magnetic piece 25... and the non-magnetic piece 26...
...and the metal plates 24, 242.
Between the magnet pieces 25... and the non-magnetic pieces 26
The reflector plate 27 is fixed over the entire length of the back surface of the carriage Y.
The horizontally elongated sheath-like part 21' of the casing 21 attached to the casing 21 is fitted with iron so that it can slide freely within a predetermined range on the left and right, and its back surface (Fig. 7) is connected to the rear entrance of the sheath-like part 21'. exposed. The exposed surface (back surface) of the reflector plate 27 is a light reflecting surface, but a large number of rectangular holes 27' forming a non-reflecting surface are formed along almost the entire length of the needle bed x. The striped needles 28 are arranged in rows at the same pitch as the pitch of the rows of striped needles 28. On the other hand, the distribution wall 2 is a timing pulse generator (i.e., a light emitting device) that generates timing pulses in accordance with the running timing of the carriage Y by irradiating the reflection plate 27 in front of the distribution wall and detecting the reflected light from the reflection plate 27. A plurality of combinations of elements and light-receiving elements 29 are fixedly arranged at intervals slightly shorter than the length of the reflecting plate 27. Therefore, at least one of the plurality of timing pulse generators 29 is always connected to the reflector 2.
7, and when carriage Y is run,
As the reflection plate 27 moves accordingly, the timing pulse generator 29 facing it...
. . . As shown in FIG. 11 [V], it is clear that a timing pulse is output every time the carriage Y moves by one pitch of knitting needles. In this way, a plurality of timing pulse generators 29 generate timing pulses while changing sequentially every time the carriage IJY travels a predetermined length.
... are connected to one output system, and from this output system, no matter where the carriage Y is in the needle bed x, timing pulses are supplied as if from one timing pulse generator. Timing pulses are output continuously as shown below. Therefore, the digital electrical signals stored in the memory device MEM of the previous generation can be read out in accordance with the traveling timing of the carriage Y, regardless of the position of the carriage Y.
In this storage device, as described above, the digital electric signals are stored separately for the left scanning and the right scanning as the scanning member 2 moves along the carriage Y. This must be done in accordance with the running direction of the carriage Y. So next,
A carriage traveling direction detection mechanism for detecting the traveling direction of the carriage Y will be described in order to store and read out the digital electric signal in the storage device MEM according to the traveling direction of the carriage Y. As mentioned above, the upper and lower two metal plates 24, 242 of the current collection assembly D are magnetically charged, and the protruding portions 24, ′, 242′ at multiple locations at their rear ends are connected to the power distribution wall 20. It is constantly attracted to a horizontally elongated conductive plate 30, which is a conductive material and also a magnetic material, which is attached to the entire front surface of the board through an electrically insulating material. As mentioned above, the current collector assembly D is equipped with steel so that it can freely slide within a predetermined range in the sheath-like part 21' of the casing 21, and the current collector assembly D is moved to the left by the carriage Y. When the carriage Y is moved to the right, it slides to the right sliding limit position against the casing 21 and then moves together with the carriage Y, and when the carriage Y is moved to the right, contrary to the above, it slides to the left sliding limit position. After being forced to do so, they will move with it. That is, as the carriage Y is reversed in its running, the current collector assembly D is moved to the left and right with respect to the casing 21. This current collector assembly D is shown in Figure 7 (rear view).
As shown in detail in , the piece 311 is
The casing 21 is provided with a resilient switch piece 33 and a terminal 34 inside the cavity 321 that receives the piece 311. Since the current collector assembly D is tilted to the right, the bridge 311 is separated from the switch piece 33 and the switch piece 33 is separated from the terminal 34, resulting in an electrically non-conductive state. When the current collector assembly D is shifted to the left side, the switch piece 33 is placed in the position of the piece 311.
When pressed by the terminal 34, it comes into contact with the terminal 34 and becomes electrically conductive. Therefore, the switch piece 33 and the terminal 34 are
The mitt switch, therefore, also constitutes the carriage running direction detection means d, which is a contact piece 35 provided on the right side of the rear surface of the casing 21, as shown in FIG.
The contact piece 35 is electrically connected by the lead means 36.
However, the conductive plate 3 attached to almost the entire length of the front surface of the distribution wall 20
7 (see Figures 2 and 4),
The carriage traveling direction detecting means d is electrically connected to the necessary electrical and electronic circuit elements housed in the control box B on the X side of the knitting machine body, and as shown in FIG. This outputs a binary electrical signal that inverts from "H" to "L" or vice versa. Thus, the aforementioned storage device MEM is controlled by this binary electric signal, and the storage of the digital electric signal in it and the reading thereof are carried out according to the running direction of the carriage Y. The electrical signal must be supplied to one of the pair of knitting needle selection mechanisms CI and Cr that performs effective selection. Therefore, next, the digital electric signal read above is sent to the rope needle selection mechanism according to the traveling direction of the carriage Y.
A switch mechanism for switching and supplying the power will be explained with reference to FIGS. 5 to 7. As mentioned above, the upper and lower two metal plates 2 of the current collector assembly D
4, 242 is both a conductor and a magnetic material,
It is in constant contact with the conductive plate 30 on the x side of the knitting machine body, which is also a conductive material and a magnetic material.
In other words, power can be supplied from the X side of the knitting machine body. These two metal plates 24, 242 have two
Notch hole 2 that penetrates vertically and horizontally with a predetermined length at a certain point
There are 41 and 24r, each with a casing 21
Embedded conductive pieces 381 and 38r penetrate therethrough. When the carriage Y is in the left direction, the current collector assembly D is biased to the right side, so that the right conductive piece 38r engages with the left green part of the right notch hole 24r, and only that part is on the side of the knitting machine main body X. When the carriage Y is in the right row, only the left conductive piece 381 is electrically connected to the conductive plate 30, contrary to the above. As shown in FIG.
The conductive piece 381 on the left side is connected to the electromagnet 40 of the knitting needle selection mechanism Cr on the right side by the lead means 41.
It is electrically connected to. Therefore, when the carriage Y is on the left, the digital electric signal from the x side of the knitting machine body is supplied to the knitting needle selection mechanism on the left through the conductive piece 38r on the right, and when the carriage is on the right, the electromagnet 401 is supplied to the knitting needle selection mechanism on the left. is supplied to the right electromagnet 401 through the left conductive piece 381, and the conductive pieces 381, 38
r and the notch holes 241, 34r are, so to speak, left and right switch means E1, E for switching the supply of the digital electric signal.
It can be said that it constitutes r. Next, regarding the left and right knitting needle sorting mechanisms CI and Cr, the fourth
Referring to Figures 5, 6, 8, and 9, both have substantially the same structure, although the arrangement of component parts is symmetrical. The electromagnet 40 mentioned above is installed on a carriage plywood 41, and the upper and lower magnetic pole plates 42, 422 have horizontal portions 43a of magnetic conductive bodies 43, 44 integrally molded with magnetic material, respectively.
, 44a are joined from above and below, respectively, and different magnetic poles are excited in both magnetic conductors 43 and 44 by excitation of the electromagnet 40. On the other hand, a bat guide 45 made of a non-magnetic material is fixed to the lower surface of the carriage plywood 41. This bat guide body 45 has a bat passage 45a that is long in the left and right directions on its lower surface, and in the bat passage 45a,
The butt 28' of the striped needle 28 set at the needle selection receiving position can be received through the side cam 46. The front and back of this bat passage 45a are almost the same as those of the bat 28', and its upper wall surface is a tapered surface where the outer half portion 45b on the outside as seen from the carriage Y descends inward, as shown in FIG. The inner half 45e is the bat 2.
The horizontal plane is slightly lower than the steady height of 8' (solid line in Figure 4). Therefore, in the process of passing through the bat passage 45a, the bat 28' is gradually pushed down from the middle of the outer half 45b against the leaf spring 47 (FIG. 4), and comes into pressure contact with it at the inner half 45c. , it passes through the bat passage 45a in a tight state, and then returns to its normal height again by the action of the leaf spring 47. With respect to the bat guide body 45 having such a structure, the one guide body 43 has a carriage plywood 4 continuing from its hanging portion 43b.
The outer lower end portion 43b of the vertical extension portion 43c extending left and right on the lower side of the bat guide member 45 is embedded in the thickness of the bat guide 45, and the flat lower end surface of the outer lower end portion 43d is placed above the bat passage 45a. It is flush with the inner half of the wall and faces approximately the center of the bat passage 45a. Furthermore, this guide body 43 has a central lower end portion 43 that is a part of this vertically extending portion 43c and extends inwardly following the outer lower end portion 43d.
The lower green edge of e gradually slopes downward toward the inside, and the front side of the lower edge is
As shown in the line cross section), it is chamfered 43'e. The other magnetic conductor 44 is provided with a notch 44d between an outer half 44b and an inner half 44c of the vertical part that hang down from the front end of the horizontal part 44a and extend left and right. The magnetism acts on the outer half 44b, but hardly acts on the inner half 44c. The magnetically conductive body 44 has its vertical portion hanging down along the rear wall surface of the bat guide 45 which is inclined rearward inward from the inner end of the bat passage 45a, and The outer half 44b that guides the knitting needles 28
It is located behind the outer lower end portion 43d of the 10,000 magnetic conductive members 43 at a middle t on the left and right sides (FIG. 8), which is approximately the same as the arrangement pitch of
The front surface of the outer end portion thereof faces the rear wall surface of the bat passage 45a. Thus, the selection of the rope hooks 28 with the butt 28' inserted into the butt passage 45a is carried out as follows. The bat 28' that has entered the bat passage 45a is moved to the carriage Y.
As it runs, it is gradually pushed down while its front and rear movements are restrained, and its head end is pressed against the lower end surface of the outer lower end 43d of one magnetic conductor 43, and the other magnetic conductor 43 is moved only during the passage t. The rear surface is brought into pressure contact with the front surface of the outer half portion 44b of 44. If the electromagnet 40 is in an excited state during this time t, that is, while the carriage Y is traveling for one pitch of knitting needles, the conductor 43 is excited to have different magnetic poles, for example, the S pole and the N pole, respectively. A bat 28' is placed between the two guide bodies.
A kind of magnetic path is formed through the magnetic conductor 43, and the outer lower end 43d of the magnetic conductor 43 is straight, but the outer half 44b of the magnetic conductor 44 is straight.
Because the bat 28' is angled rearwardly, the butt 28' will be biased slightly rearward along its outer half 44b'.
- As shown in detail in FIG. 9, this rearwardly biased butt 28' connects the rising portion 44e of the inner half 44c of the magnetic conductor 44 (not affected by the electromagnet 40) and the magnetic conductor 44.
Since the magnet piece 48 is disposed between the rising part 43f of the magnetic conductor 43, it is attracted to the inner half part 44c (the position indicated by the dotted line in FIG. 9), and further tilts backward to lower the magnetic conductor 43. It rises to a steady height on the rear side of the slanted central lower end 43e, advances further, pushes open the opening/closing piece 50 that is closed by the action of the spring 49, and opens the rear guide path by a group of cams arranged on the back surface of the carriage Y. It's starting to pass. On the other hand, when the electromagnet 40 is in a de-energized state, the butt 28'
is not attracted by the inner half 44b of the magnetic conductor 44, so it travels straight, and the chamfer 43'e of the lower edge of the magnetic conductor 43
It is guided to the front side of the guide body 43 (the position indicated by the chain line in FIG. 9), and further advances to pass through a front guide path different from that in the case of excitation. Note that the compensating magnet piece 5 is attached to the hanging portion 43b of the guide body 43.
1 is attached in such a way that its magnetic pole is oriented in a direction that cancels out the magnetic poles of the four electromagnets, so that the electromagnet 4
The residual magnetism that exists in the non-excited state after zero excitation is erased, thereby making it possible to perform the sorting operation more reliably. The knitting needles 28 that have entered the butt passage 45a are subjected to the sorting action one by one as described above, but even if the knitting needles 28 that have entered the butt passage 45a are outside the range of the left and right cursors 41 and 4r mentioned above, If the electromagnet 40 is located at , Next, such a configuration will be explained. The casing 21 on the back side of the carriage Y has a cavity 321 (FIG. 7) on the left side and a similar cavity 32r (FIG. 5) on the right side thereof, in which the current collector assembly D is inserted. A piece 31r is placed in the opposite direction to the piece 311 on the left side. And casing 21G, left and right hollow spaces 321, 32r
On the upper wall, on the rear extension line of the sorting point (the part in t) of the left and right knitting needle sorting mechanisms CI, Cr,
Left and right movable magnet pieces 521 and 52r are provided so as to be movable up and down along the respective guide holes. Both of these movable magnet pieces 521 and 52r move up and down as the pieces 311 and 31r move, respectively, and when the current collector assembly D is in the right-biased bridge position, the left side is in the ascending state and the right side is in the descending state. , and when the chair is in the left leaning position, the relationship is reversed. On the other hand, cursor 4
1 and 4r are mounted on the forward-slanted part of the upper end of the power distribution wall 20 so as to be able to freely move left and right, and are provided with reed switches 53 on the lower surface of each, which are operated by a spring force. It is electrically connected to a horizontally elongated conductive foil 55 attached to the entire length of the forward-slanted lower surface of the power distribution wall 20 through a contact piece 54, and no matter which position the reed switch 53 cursors 41, 4r are located, the required electricity in the control box B;
It is designed to be electrically connected to an electronic circuit. The IJ switch 53 is positioned above the traveling line of the movable magnet pieces 521 and 52r on the carriage Y side, and when the carriage Y is moving to the left, the left movable magnet piece 521 is in the raised position. Depending on the situation, when it is directly under the left cursor 41, its read switch 53 will be activated.
is turned on and the pulse shown in Figure 11 [Skin] is obtained.
In addition, when moving to the right, when the right movable magnet piece 52r comes directly under the right cursor 4r, its read switch 53
is turned on and the pulses shown in the same figure are obtained, and during the interval between these two pulses, the digital electrical signals stored in the memory device MEM are sequentially outputted to the memory device MEM as described above. During this sorting, pattern knitting is carried out, and the force-sols 41 and 4r can be said to constitute a pattern knitting end indicating means for indicating the pattern knitting end. The mechanical configuration is as described above, and next, the overall electrical and electronic configuration will be explained with reference to FIGS. 10 and 11.

Its storage in the memory device M is carried out at a predetermined address related to the scanning direction of the scanning member 2, and therefore to the running direction of the carriage Y, under the control of the storage addressing circuit G and the carriage running direction detection means d. It's becoming like that. That is, the memory addressing circuit G includes an up/down counter, and receives sampling pulses from the sampling pulse generator a.

It counts [0] [m],
Output signal [W] from the carriage running direction detection means d
, the addition/subtraction operation can be switched between the left row and the right row of the scanning member 2, and one stage scanning of the knitting pattern entry field 11 of the knitting pattern recording card, that is, the total minimum of one stage of the machine row. The 60-bit digital electrical signal related to the section (in this example, 6 units) scanning is stored in the storage device MEM separately for when it is obtained by the left row of the scanning member 2 and when it is obtained by the right row. It is now stored at a fixed address. On the other hand, the stored digital electrical signals are discussed as follows. The pulses [Skin] and [Yanagi] from the cursors 41 and 4r are supplied to an effective needle selection range indicating signal forming circuit consisting of flip-flops, etc., so that the pulses from the cursors 41 and 4r are Signal according to pulse interval [
K] is formed, and the signal is applied to the effective timing pulse forming circuit 1 consisting of a gate circuit, etc., and from this, the same number of timing pulses [X] as the number of knitting needles 28 located between the cursors 41 and 4r are sent to the carriage Y. One piece is output every time the knitting needle moves one pitch. This timing pulse [X] is applied to a carriage position detection circuit J including an up/down counter, and is thereby added or subtracted according to the traveling direction of the carriage Y. By the way, the count value of this detection circuit J is arbitrarily set by unit pattern green stitch number setting means K (this manual operation section is located on the operation panel 3 of the control box B), which is a count value presetting means ( (12 in this example), and each time the set number of timing pulses [X] is added or subtracted,
As shown in [Xm], the same numerical value (parallel binary electric signal) is obtained repeatedly. In other words, it can be said that this carriage position detection circuit J attaches repeat numbers to the knitting needles 28 located between the cursors 41 and 4r in a fixed direction. Therefore, the output of this detection circuit J is sent to the storage and readout control circuit F as the effective needle selection range instruction signal [K].
It is supplied as a logical address designation signal to the storage device MEM only during the output of ] is outputted from the storage and readout control circuit F, and then supplied to the drive signal forming circuit L including the Asodo circuit that is supplied with the effective needle selection range instruction signal [K], and the signal [Melon] is output. The switch means EI as a binary electric signal during the "H" output of
Alternatively, one or four Cr electromagnets are output to one of the knitting needle sorting mechanisms on the side that performs effective sorting operation through the Fr.
Thus, the knitting needle 28 between the cursors 41 and 4r is [XW
] As shown in ], the IZ book is considered as one block, and the leftmost 4th section of the knitting pattern entry column 11 and the 12th section from that
They are sorted according to the form of the knitting pattern drawn between the smallest section on the right side of the piece (for example, in Fig. 11, the filled-in one is the back-man-bang-ore, and the one without is the front-bang-hashi). By the way, as is clear from the above, the knitting pattern entry column 11 of the card 1 is scanned over the entire length of the left and right ends, and all bits of the digital electrical signal obtained by one scan are stored in the storage device M. However, the number of bits determined from this is determined by the unit pattern knitting needle number setting means (presetting means) K. For example, if it is set to "12", even if the knitting pattern entry column 1
1. Even if a knitting pattern is recorded further to the right of the 12th minimum section from the left edge on the top, it will be scanned and temporarily stored in the storage device M', but it will not be used for needle selection. It is not read out as a signal to perform the operation. With the above configuration, it is possible to knit a unit pattern according to the knitting pattern on the card, but the main knitting machine further changes the actual pattern of the knitted pattern by the above operations without changing the knitting pattern. This can be changed by operating the operating members on the panel 3 (Fig. 1), which will be explained next. The pattern left/right reversal means M is such that the output electric signal is reversed from "H" to "L" or vice versa as shown in [phantom] by operating the sliding door of its operation part. M] is compared with the output [W] of the carriage traveling direction detecting means d by a comparison circuit N (exclusive OR)
The direction of addition and subtraction of the up/down counter of the carriage position detection circuit J is designated by the comparison signal [Fox]. Therefore, the count value of the carriage position detection circuit J is determined by the operation of the pattern left/right reversing means M to determine whether the carriage Y takes the above-mentioned [Xm] relationship or the [X skin] relationship when traveling in a certain direction. Even if the knitting pattern on the card is the same, [Xm] and [X
In the case of [skin], the pattern knitted is as if the left and right sides were reversed. Next, the needle selection mode reversing means P outputs an electric signal similar to that of the pattern left/right reversing means M by imitating cutting of its operation section, and supplies it to the drive signal forming circuit L. By operating this means P, it is determined whether the output from the drive signal forming circuit L will be as described above [X] or a signal obtained by inverting it. Therefore, by operating this means P, the front and rear sorting mode of the knitting needles 28 can be reversed, thereby making it possible to reverse the ground tie of the pattern to be knitted without changing the knitting pattern on the card. be. Note that in the above, storage in the storage device MEM is performed for all bits of digital electrical signals related to one-stage scanning;
In this readout, only the part of the set bit number is retrieved and unit pattern formation is performed. However, it can be implemented in substantially the same way. In this case, the count value of the up/down counter of the storage address designating circuit G may be preset by the unit pattern line stitch number setting means (presetting means) K. As detailed above, the present invention has the following effects. ■ The effective needle selection range is divided by setting a pair of left and right effective needle selection range indicating means at arbitrary positions in the longitudinal direction of the needle bed, and only while the carriage is traveling within that range, the digital data stored in the storage device is stored. Since it outputs electrical signals, the width of the pattern knitting and its position on the needle bed can be determined arbitrarily in advance.In addition, the effective left and right needle selection ranges can be used to indicate in which range on the needle bed the pattern will actually be knitted. The means can be immediately and clearly known simply by visual inspection. ■ Unless the carriage is located corresponding to the left and right effective needle selection range indicating means, this is electrically detected, and the carriage is not located between the left and right effective needle selection range indicating means, the storage device is Since the setting operation and therefore the effective needle selection operation for all needles are not performed, the movement of the carriage to the left and right is detected and the reversal movement of the carriage is memorized only while the carriage is running between the left and right reversal positions. As in the case of promoting the device, the reading operation of the storage device is performed by small steps of reciprocating left and right unrelated to the arrangement operation of the carriage, and there is no disadvantage that incorrect arrangement occurs in the frame, Pattern knitting can be accurately performed only within an arbitrary range determined by the effective needle selection range indicating means. ■ The knitting pattern recorded on the knitting pattern recording medium is read out as a digital signal of a predetermined number of bits by scanning by a scanning section, and the number of bits of the digital electric signal of the predetermined number of bits is stored in the storage layer or The number of bits to be read out is manually set arbitrarily by the unit pattern line stitch number setting means, and only the set number of bits is sequentially and cyclically retrieved from the storage device, so that the knitting pattern recorded on the knitting pattern recording medium is Even without changing the unit pattern, the form, size, etc. of the unit pattern can be freely changed by simple manual operation. ■ The scanning device is installed behind the needle bed of the knitting machine main body, and the manual operation section for determining the number of needles for unitary knitting is placed on the operation panel, which is also installed at the rear of the needle bed. It is convenient because the number of knitting needles (number of needle selection units) for knitting can be manually set at the rear of the needle bed while viewing the knitting pattern on the knitting pattern recording medium.
