Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a knitting information reading device for reading knitting command information recorded (programmed) on a predetermined recording medium in order to perform desired knitting in a knitting machine.

Conventionally, this type of knitting information reading device is well known, in which the pattern of the pattern to be knitted is recorded in a multi-stage perforation array on a card, and the presence or absence of perforations in each row is mechanically detected. It is being

However, in this case, if you want to create the pattern of the pattern you want to knit, you have to drill holes in the card regularly, one at a time, at fixed coordinate positions. It is necessary to subdivide the pattern representing one unit pattern to be made into pattern elements (minimum constituent units of the pattern, corresponding to the above-mentioned holes) in advance, and record each pattern element in a regular arrangement. Uniform organization
The pattern to be represented must be digitally recorded in advance for each knitting needle, and this recording work is troublesome and requires special care.

Therefore, the present invention does not have to subdivide patterns representing knitting patterns into pattern elements and record them digitally, but can simply record them analogously on a peta, just like drawing a picture. Also, when reading the pattern recorded in this way, it is possible to read it as a digital electrical signal corresponding to each knitting needle, and this makes it easy to record the pattern representing the pattern to be knitted. A digital electrical control method that allows you to easily perform various operations that were previously impossible, by reading the digital electrical signals and controlling the process from the reading to the final needle selection. Furthermore, function information indicating necessary functional operations such as thread exchange, feeding condition of the recording medium, and start or end of needle selection operation can be recorded on the same recording medium as the recording medium that records the pattern to be knitted. By recording the function information, the function information can be read in the same way as reading the above-mentioned mold, and thereby the required function operation that has been recorded and programmed on the recording medium in advance can be read into the above-mentioned mold. Therefore, we have proposed a completely new knitting information reading device that can perform the reading at any required point in time related to the needle selection operation, and can also perform the above reading with a very simple configuration.

The present invention will be explained in detail below with reference to an illustrated embodiment applied to a home-use hand knitting machine.

First, an overview of the entire hand knitting machine to which the present invention is applied. This will be explained with reference to FIG. 1. A knitting machine main body X having a needle bed In addition to this reading device A, there are provided on the operation panel 2 manual operations used to manually operate various machines to be described later. A control box B containing various electrical and electronic circuits, which will be described later, is also installed behind the needle bed x. Switch activation piece 3e for needle selection range setting
, 3r are mounted at arbitrary positions, and on the back side of the base plate 4 of the carriage Y that runs on the needle bed In response to electrical signals obtained by scanning the knitting pattern, the rows of knitting needles on the needle bed A pair of knitting needle sorting mechanisms are arranged at a predetermined length apart on the left and right sides.

The reading device A has its scanning member mounted on a carriage Y.
By automatically scanning the information recorded on the card 1 in a horizontal line in relation to the travel of the carriage (more specifically, when the carriage Y approaches the switch activation piece 3e or 3r), the corresponding electric power is It is designed to output a signal,
Further, subsequent processing of the electrical signals is performed by an electronic configuration, and power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms, for example, by a tension member 5 that applies tension to the knitting yarn. The carriage Y is controlled by the cord 6 which is passed through the switch actuating piece 3e,
By reciprocating the knitting needles beyond the left and right sides of switch 3r, only the knitting needles within the distance between the switch activation pieces 3e and 3r are at a rest position where they are not subjected to any sorting action, even if the needles are within the range of effective sorting action. (excluding things).

First, the mechanical structure of the reading device A, which is an embodiment of the present invention, will be specifically explained with reference to FIGS. 2 to 6.

The entire reading device A is mounted on a frame 7 further behind the rising wall X1 at the rear end of the needle bed x, and first the recording medium transport mechanism therein, that is, the knitting program card 1 is loaded and transported. To explain the mechanism for this, endless sprocket belts 8e and 8r, which are feeding members, are mounted on the left and right sides of the frame 7 so as to be able to circulate. The sprocket belts 8e and 8r are connected to the left and right perforations 1'' of the formation program card 1.
Sprockets 8'' that fit into the left and right sprocket belts 8 are protruded from the outer circumferential surface at regular intervals.
e, 8r and a card guide plate 9 with a U-shaped cross section disposed below between them, and then insert the card 1 between the perforations 1'' and the sprocket 8.
By fitting the sprocket belt 8
e, 8r can support the card 1 in a U-shaped folded state, and in this supported state can be circulated by the transfer drive mechanism a installed on the right side of the frame 7, so that
The card 1 can be transferred in the direction in which the perforations 1'' are arranged.

That is, each sprocket belt 8e, 8r has a lower large pulley 10e, 10r and a small pulley 11f diagonally above it, as shown in FIGS. 3 and 4 (belts 8e, 8r are partially cut out). 11r, and the left and right large pulleys 10e and 10r are connected to the drive shaft 12.
The left and right small pulleys 1' and 11r are connected to each other by a rotating shaft 13, and furthermore, the drive shaft 12 is integrally connected to the ratchet wheel 14 of the transfer drive mechanism a. By rotating this ratchet wheel 14, the left and right sprocket belts 8e, 8r are rotated.
At the same time, they are beginning to move cyclically.

As shown in FIGS. 2, 4 and 5, the transfer drive mechanism a has a normal transfer piece 15 on the front side of the ratchet wheel 14.
Further, a reverse feed piece 15'' is arranged on the rear side, and both of these feed pieces 15, 15' are connected to a pair of electromagnetic plungers 17, 17'' of 16, 1'' by pins 18, 1'', respectively.
The forward or reverse direction of the ratchet wheel 14 is determined by which of the electromagnets 16 and 1' is driven.

That is, both the sending pieces 15, 15'' are always held together by the springs 19, 19'' acting on them individually and the spring 20 stretched between them.
2" is set at the upper limit retracted position where it does not engage the ratchet wheel 14, but the corresponding electromagnet 16
, 1' are repeatedly energized and deenergized by inputting a pulse electric signal, and as the plunger 17 or 1r moves up and down, the guide pieces 22 and 23 rotate slightly, respectively.
Alternatively, it moves up and down along lines 22'' and 235 to repeatedly engage and disengage with the ratchet wheel 14.

Therefore, depending on which one of the pair of electromagnets 16, 1' is driven, the forward or reverse direction of the ratchet wheel 14 is determined, and it also determines whether the card 1 is sent in the forward direction (the second direction). (Bottom side of the figure) This determines whether to send the data in the opposite direction.

As mentioned above, the card 1 optically scans horizontally in a straight line, and if there are irregularities on the line that is currently being 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 stretched between the left and right sprocket belts 81 and 8r, and further on the left and right sides of the left and right belts 81 and 8r, the left and right side edges of the card 1 are Left and right card holding pieces 25f that lightly press the respective parts,
It is equipped with a 25r.

That is, as shown in FIG. 3, the upper surface of the card receiving plate 24 is a flat inclined surface that is high on the rear side and low on the front side.
Further, each card holding piece 25', 25r has a fulcrum on the axis of the drive shaft 12, as shown in the side view of the right side in Fig. 6 (cross section taken along line I-1 in Fig. 2). It can be rotated around the center, that is, opened and closed, but the spring 26
The card 1 is urged rearward, that is, in the closing direction, by the perforations 1 on its left and right sides as described above.
sprocket belt 8e, 8r sprocket 8''
By fitting the card into the slot and pressing it with the card holding pieces 25e and 25r, the card is transferred along the flat inclined upper surface of the card receiving plate 24 while remaining in close contact therewith.

As described above, the portion of the card 1 along the card receiving plate 24 always forms a flat slope over almost the entire length on the left and right, and next, the card 1 is scanned horizontally and horizontally in a straight line in this flat sloped portion. The scanning mechanism will be explained below.

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 b is mounted on these so as to be slidable left and right.

That is, as shown in FIG. 3, the scanning member b has left and right through holes 291 provided in its main body, the traveling body 29, slidably fitted into the upper guide rod 27, and
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 permanent magnet 32 has, for example, an N pole on its upper full length and an S pole on its lower full length, and the lower guide rod 28 is made of a magnetic material, and is turned on by passing a current through the coil 31. The current crosses the magnetic field that the permanent magnet 32 is always attached to, and the magnetic force acting between them causes the traveling body 2 to
9. Therefore, the scanning member b automatically moves to the left or right along the guide rods 27 and 28 depending on the direction of the current flowing through the coil 31. That is, the coil 31
The permanent magnets 32 constitute a kind of linear motor that uses the permanent magnets 32 as a stator.

At positions corresponding to the left and right ends of the permanent magnet 32, as shown in FIG. 7 (cross section along the line ■-■ in FIG. 2), left and right limit switches 33e, which function to switch the polarity of the current flowing through the coil 31, are installed. 33r is placed.

The limit switch 33e on the left end is turned on when the scanning member b collides with the left row, and the right limit switch 33r is turned on when the scanning member b collides with the right row. switch 33
It moves left and right between e and 33r, and these left and right limit switches serve as the left and right stroke ends, and as will be described later, the scanning member b is always located at the left stroke end, which is its original position. , in relation to the reversal of the carriage Y, it moves clockwise at a fairly high speed from its original position to the right stroke end, and immediately reverses (turns around) as soon as it reaches the right stroke end. The left and right limit switches 33e and 33r are configured to automatically and continuously feed back to the original position, and the left and right limit switches 33e and 33r respectively check whether the scanning member b is at the original position or in the reverse position (right stroke end). It functions as a means to detect whether or not it exists. As shown in FIG. 3, the upper extension 29'' of the traveling body 29 of the scanning member b extends diagonally upward on the rear side and then diagonally downward, and its leading edge is on the slope of the card receiving plate 24. It faces it at a close position, and at its tip is a so-called light-receiving element consisting of a reading element, that is, a light-emitting element, and a light-receiving element that receives reflected light that is reflected from the first surface of the card and converts it into an electrical signal. Equipped with a photoelectric sensor c.

As the scanning member b moves, the 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. I will call it that.

Next, card 1 will be explained with reference to Figure 2. It is semi-transparent, and the perforations 1"
On the white surface in between, there is a knitting pattern information recording section, that is, a knitting pattern information entry field 1 which is a part for recording the knitting pattern.
, and the function mark entry field 1r, which is the function information recording section on the right side, that is, the part where the function mark is recorded, are set to the same color as the emitted light color of the light emitting element of the scanning sensor c, and a color that the light receiving element does not discriminate (for example, the above mentioned function mark entry field 1r). When a red light emitting diode is used as the light emitting element, the grid dividing line (red) is created by displaying it in advance by an appropriate display method such as printing, and at the left end of the knitting pattern entry field 1p, A large number of control marks 34, which can control the feeding amount of the card 1 by being read by the scanning sensor c, are placed, for example, with slightly thick black horizontal lines at regular intervals in the direction in which the perforations 1'' are lined up. It has been recorded in advance by displaying it at

The spaces between the entry fields 1p and 1r and between the entry field h and the feed control mark 34 are blank. In the above-mentioned knitting pattern entry MIP, 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 margin, the above-mentioned The numbers representing the stitches are displayed in the same color as the grid division lines.

To be more specific, in the knitting pattern entry field 1p, one minimum section, that is, a reporter grid corresponds to one stitch,
The horizontal arrangement, or row, corresponds to one knitting needle, and the vertical arrangement, or column or wale, corresponds to a so-called unit in which n horizontal rows of stitches form one group. When knitting a pattern, consider the vertical line at the left edge and the vertical line n vertical lines to the right as the boundary line, and draw the picture (knitting pattern) corresponding to the unit pattern to be knitted between them. ) is drawn in black using an appropriate writing instrument such as a pencil, for example, as shown in the figure.

For example, when knitting a unit pattern of 12 stitches in a horizontal row by selecting the knitting needles of one pot as a unit of one group, the vertical line of the left edge and the vertical line of the first pot from it are It is intended to draw a picture within the range.

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

This is because the reading is performed by sampling each reporter grid, and this will be explained in detail later. Furthermore, in the function mark entry field 1, the horizontal line is on the same line as the horizontal line in the knitting pattern entry field 1p, and the vertical line is parallel to the vertical line in the knitting pattern entry field 19, and the function mark entry field 1 is The rows (vertical arrangement) of the register lattice in column 1 are aligned on the same line as those in knitting pattern entry column 1p, and there are the same number of rows (vertical arrangement).
For example, if the knitting pattern entry field 1p is 3
There are 6, but there are now 4.

The function mark entry column 1 is used to mark (for example, fill in black) any mark grid when performing a required function operation.In this example, a total of four columns of the mark grid are used. The first column on the left of the columns (vertical arrangement) is for programming the forward direction of the card 1, the column to the right is for programming the reverse direction of the card 1, and The other two columns are used to program 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 row of the reporter grid in the knitting pattern entry field b. As will be described later, the card 1 is automatically advanced to each stage of the reporter's grid.

Furthermore, in addition to the eight types of display as described above, card 1 also has a needle selection unit setting field L for programming the number of needle selection units in the same color below the knitting pattern entry field 1p. It is displayed. This setting field L
is the required number of individually independent rectangular grids 35...
... are displayed in a row at regular intervals in the horizontal direction, and each grid is unique for setting a fixed number of needle selection units. The set number of units is different from each other, and the number of set units increases in a predetermined base number toward the right, and a number representing the number of needle selection units is displayed at the bottom of each reporter grid 35 in the same color. is displayed in advance.

In this example, the number of reporter grids 35 is six in total, and the one on the left is the needle selection unit number R6, which is expressed as Rl2, l8, 24, 3O, and 36J in hexadecimal. The needle selection unit setting field L is also scanned by the scanning sensor c of the scanning member b, and determines which of the marking grids 35 to mark. Therefore, the number of needle selection units is determined. For example, when knitting a unit pattern using one pot of knitting needles, the reporter grid 35 labeled R12 is filled in black. Furthermore, a search mark 36 is preliminarily displayed on the card 1 so that only the setting field L 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 composed of, for example, a horizontally long black band with the same vertical width as the vertical width of the marker grid 35 in the setting field L, and its position on the card 1 is in the column of the marker grid 35. On the extension line of the setting direction and the feed control mark 34...
..., but its width is longer to the right than that of the feed control mark 34..., and is between 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 8e and 8r as described above and the scanning member b is at the original position (left stroke end), the card 1 is within the length range of the feed control mark 34. A predetermined position is read by a scanning sensor c, and the card 1 is automatically transferred according to the feed control mark 34 only when the scanning member b is in the original position. When the scanning member b reaches the reversal position (right stroke end), the register grid row on the right side of the function mark entry field 1f can be read, and the range between these two reading positions is It is adapted to be read while the scanning member b is being displayed.

Therefore, the card 1 is created by scanning the needle selection unit number setting column 1s with the scanning sensor c of the scanning member b before starting the knitting operation, and then repeating automatic step-by-step feeding with the knitting operation. Therefore, the knitting pattern entry field b and the function mark entry field 1 are scanned for each row by the same scanning sensor c, and such scanning is performed by the aforementioned forward and backward movements of the scanning member b. However, as will be described later, only the electrical signals associated with the forward (rightward) stroke of the scanning member b are effectively extracted from the electrical signals associated with the scanning of both the forward and backward strokes. It is something.

By the way, as mentioned above, in the knitting pattern entry column 19,
The knitting pattern representing the unit pattern to be knitted is drawn in a small pattern, and the scanning sensor c of the scanning member b scans the knitting pattern horizontally in a straight line for each row of the knitting grid. The electrical signal related to step scanning is the first
As shown in Figure 3 [■] (an example when card 1 is scanned along the P2-P2 line in the same figure), the aspect of the knitting pattern in the first tier of the kinin grid, that is, the knitting pattern 1
The electrical signal obtained by scanning is a square wave according to the horizontal scanning mode, and if it is only this, 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 will not be written. The function mark entered in column 1 is also attached to the scanning sensor c, just like the knitting pattern above. In addition, the search mark 36 displayed in advance is also read in the same way and becomes an electrical signal in the same electrical system. However, these three types of electrical signals are mutually separated, and the electrical signals related to reading the knitting pattern are converted into digital electrical signals that correspond to needle selection in a one-to-one relationship, and the electrical signals of the function marks Electrical signals related to reading are also stored in each register grid column (1f) of the function mark entry field (
Next, the mechanical structure of the sampling mechanism that performs this operation, that is, the sampling operation, will be explained with reference to FIGS. 2 and 3.

The frame 7 is located behind the traveling body 29 of the scanning member b.
The horizontally long plate-shaped linear encoder 37 is connected to the guide rod 27.
, 28 and horizontally suspended. R;A encoder 3
In order to sample only the search mark 36 on the card 1, 1 is placed at a position corresponding to the blank space between the feed control mark 34... and the knitting pattern entry field 1p on the card 1. A predetermined number of knitting pattern samplings (12 in this example) are provided to sample the knitting patterns drawn in the knitting pattern entry field 1p on the right side of the slits 38s for search mark sampling nogs. slit 38
p...... from the position corresponding to the left edge grid row in the knitting pattern entry field 1p, move to the right in a straight line at regular intervals, and cross over the right edge of the entry field b. A predetermined number of function marks (
In this example, four (4) function mark sampling slits 38f are formed in one-to-one correspondence with each reporter grid row in the function mark entry field 1.

On the other hand, on the rear side of the traveling body 29 of the scanning member b, there is a photoelectric 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 b travels, the sampling sensor d is scanned through the slits 38, 38p..., 38c.
It outputs a pulse, that is, a sampling pulse according to the above-mentioned scanning sensor c, and the sampling pulse outputs a pulse corresponding to the reciprocating movement of the scanning member b as described later. As shown in FIG. 13 [1], only those related to the outbound journey are extracted as valid ones, and after that, three types of sampling pulses, that is, the search marks 36 are extracted. One sampling pulse for sampling, 12 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 reason why we used 120 slits 38p to obtain 12 sampling pulses was because the number of rows (horizontal arrangement) of the grids in the knitting pattern entry field 1p was changed. This is to make it possible to apply a card (FIG. 20) with the number of rows of R12OJ as described later, in addition to the above-mentioned card 1 having R36J.

Therefore, for card 1 whose number of columns is R36J,
Three slits 38p correspond to each reporter lattice in the knitting pattern entry field 1p, and each reporter lattice 1
Three sampling pulses are obtained for each scan, but as will be described later, in the case of card 1 with the number of rows R36J, the above three sampling pulses are obtained as shown in Fig. 13 [XV]. Two of the sampling pulses are removed, and the remaining one sampling pulse samples the electrical signal related to the scanning of one reporter grid.

In this way, the electrical signals related to one-stage scanning of the knitting pattern entry field 1p are sampled for each reporter grid, and
As shown in the figure [X The digital electrical signals are converted into signals, and 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 signal is transferred to the carriage Y.
The needles are read out sequentially and repeatedly in accordance with the travel timing of the carriage Y, and are supplied to one of the pair of left and right knitting needle selection mechanisms (the configuration of which will be explained later) installed on the back side of the carriage Y, which is to be operated effectively. It is becoming more and more common. The reading device A, which is an embodiment of the present invention, is mechanically constructed as described above.

Next, we will discuss the mechanical configuration of the carriage Y side in sections 3 and 8.
This will be explained with reference to FIG.

As mentioned above, the main hand knitting machine automatically starts running the scanning member b 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 the carriage Y in left-right travel, and the effective scanning of the knitting pattern by the scanning sensor c of the scanning member b is performed only on the outbound journey, and a digital electric signal related to that scanning is required. are temporarily stored in the memory sequentially from left to right, whereas the actual needle selection operation is performed by reading out the digital electrical signals stored in the memory, when the left and right knitting needle selection mechanisms are The movement of the carriage Y is carried out in both directions while alternating in accordance with the running 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. The storage of digital electrical signals in the memory and their reading must be controlled by signals.

Therefore, the carriage Y is designed as shown in Fig. 8 (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. A carriage reversal switch mechanism E is installed at the center of the rear 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 slidable back and forth within a predetermined length range.

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 431 and 432. The two magnetic plates 431 and 432 are magnetic.
The lower end of the horizontally elongated hole 4″ provided in the base plate 4 and the base plate 4
The magnetic plates 431 and 43 pass through an oblong hole 4C provided in the slide vibrator 44 fixed to the slide vibrator 44.

The lower end surface of the needle 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,
On the rear side of the sheath frame 39, there are three switch parts e1 to
A microswitch e having E3 is fixedly installed, and the lever e'' of the switch e passes through a window hole 39'' provided in the rear wall of the sheath frame 39, and passes through the rear magnetic plate 43. It is inserted into the hole 43''.

Therefore, the switch actuator 40 is fitted into the sheath frame 39 so as to be able to slide freely within a predetermined range on the left and right, and because it is adsorbed to the carriage guide bar 45, When Y is moved to the left, it slides to the right sliding limit position against the sheath frame 39 and then moves with it, and when the carriage Y is moved to the right, contrary to the above, it reaches the left sliding limit position. After being slid, 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 switch one of the microswitches. In other words, the switch unit for detecting the carriage running direction generates a binary value that is reversed from RHJ to RLJ or vice versa when the carriage Y is reversed as shown in Fig. 16 [1] or Fig. 18 [■]. Electric signals can be obtained.Next, the left and right knitting needle selection mechanisms Fe and Fr, which ultimately carry out the front and rear selection of the knitting needles N, will be explained with reference to Figs. 3, 8, and 10. Although the arrangement of the electromagnets 46 is symmetrical, they have substantially the same structure.The electromagnets 46 are installed on the carriage base plate 4, and the magnetic fields above and below the electromagnets 46 are connected to each other by integral magnetic materials. One end portion of a pair of molded magnetic conductors 47 and 48 are joined from above and below, respectively, so that mutually different magnetic poles are excited in both magnetic conductors 47 and 48.

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

This putt guide body 49 has a left and right long putt passage 491 formed on its lower surface, and in the putt passage 491,
The pad N'' of the knitting needle N set at the needle selection receiving position can be received through the side cam 50.The front and rear width of this pad passage 491 is approximately the same as that of the pad N'', and its upper wall surface is similar to that of the pad N''. As shown in Figure 1.0, the outer half 492 on the outside as seen from the carriage Y is a tapered surface that descends inward, and the inner half 493 is a horizontal surface slightly lower than the steady height of the pad N''.

Therefore, it passes through this pad passage 491.

In the process, the pad N'' is gradually pushed down from the middle of the outer half 492 against the plate spring 51 (FIG. 3), comes into pressure contact with it at the inner half 493, and the pad passage 491
You will pass through it with a snug fit. With respect to the pad guide body 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 pad guide body 49 from the front side. , a part thereof faces the inner end of the putt passage 491, and the lower surface of the horizontal part faces the inner end of the putt passage 491.
The surface is flush with the inner half 493 of the upper wall surface of 91 and continues therefrom.

In addition, the other magnetic conductor 48 has a notch 481 extending halfway from the upper side in a vertical portion below the carriage base plate 4, and an outer vertical portion 482 located outside the notch 481 is provided with a notch 481 that extends from the electromagnet 46. Although the magnetism acts on the inner vertical part 483, it hardly acts on the inner vertical part 483.

The magnetic conductor 48 is arranged so that its outer vertical portion 482 is along the rear side of the pad passage 491.
At the same time as it is present inside. The vertical front surface from the outer vertical part 482 to the inner vertical part 483 is a surface that slopes rearward inward from the inner end (putt outlet) of the putt passage 491, as shown in FIG.

In addition, the horizontal width of the outer vertical portion 482 of the magnetic conductor 48 is a width t that is slightly shorter than the arrangement pitch of the knitting needles N, and the pad N'' passing through the pad passage 491 is within this width t. The rear surface is brought into pressure contact with the vertical front surface of the magnetic conductor 47, 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 portion 483 of the magnetic conductor 48 and the horizontal portion of the magnetic conductor 47 are pressed against each other. A rearwardly inclined gap passage 51 (FIG. 8) is formed between the rear side edge and the pad N''.

Therefore, the selection of the knitting needles N with the pads N'' inserted into the pad passage 491 is performed as follows.

As the carriage Y travels, the pad N' that has entered the pad passage 491 is gradually pushed down with its back and forth movement restrained, and its head end is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47, and the pad N' While passing through the width, the rear surface is brought into pressure contact with the vertical front surface of the other magnetic conductor 48.

If the electromagnet 46 is in an excited state during this width t, that is, while the carriage Y is traveling for one pitch of knitting needles, the magnetic conductor 47
By energizing different magnetic poles in the outer vertical portion 482 of the magnetic conducting body 48, a kind of magnetic path is formed between them through the pad N″, and the outer vertical portion 482 of the magnetic conducting body 48 is Putt N'' because it is tilted towards
is slightly attracted and biased rearward along its outer vertical portion 482 and deviates from the horizontal lower surface of the magnetic conductor 47 into the gap passage 5.
1, and immediately rises to a normal height on the rear side of the horizontal portion of the magnetic conductor 47.

The pad N'' that has entered this gap passage 51 is formed by a rising portion of the magnetic conductor 47 on the carriage base plate 4 and a rising portion extending from the inner vertical portion 483 (portion not subjected to the magnetic action of the electromagnet 46) of the magnetic conductor 48. Since a magnet piece 52 is disposed between the carriage Y and the carriage Y, the magnet piece 52 is subsequently attracted and biased rearward, and then passes through a rearward guide passage 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 pad N'' is not attracted to the outer vertical part 482 of the magnetic conductor 48, and is pushed down to the horizontal part of the magnetic conductor 47, and remains in the pad passage 49.
1, it continues straight ahead, rises to a steady height beyond the inner edge of the horizontal part, and then passes through a forward guide path that is different from the case of excitation described above.

The left and right knitting needle sorting mechanisms Fe, Fr should be effectively operated by switching the electromagnetic changeover switch part ♂ in the microswitch e of the carriage reversing switch mechanism E according to the traveling direction of the carriage Y. Only one 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 selection mechanisms Fe, Fr have the above-mentioned configuration, and have a pad N'' in the pad passage 491.
As described above, the knitting needles N that are fitted are subjected to the sorting action one by one by the sorting mechanism Fe or Fr on the front side of the carriage Y in the direction of movement. If the electromagnet 46 is located outside the range of the left and right needle selection range setting switch activation pieces 3e and 3r, the electromagnet 46 does not receive any excitation command and remains in a non-excited state. This structure is not subjected to the above-mentioned sorting action by the filter. Next, such a structure will be explained with reference to FIGS. 8 and 9.

The left and right switch activation pieces 3e and 3r both have a cam groove 31 running left and right on their upper surfaces, and a needle groove?
A plurality of protrusions 32 which are fitted from above are formed protrudingly on the front end of the lower surface, and a plurality of pad engagement grooves 33 are formed on the front side surface to tightly receive the pads N'' of the knitting needles N. By fitting the protrusion 32 into the rear end of the needle groove and further engaging the pad N'' in the pad engagement groove 33, the needle can be placed at any position on the needle bed X without moving left or right. Although they are the same, the shapes of the cam grooves 31 are symmetrical to each other.

That is, in the left switch activation piece 3f, the front and rear cam parts 34 and 35 forming the front and rear side walls of the cam groove 31 are arranged in such a manner that the front side is on the right and the rear side is on the left. 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, a pair of left and right needle selection end detection switch mechanisms Ge, Gr are operated by engaging the switch activation pieces 3', 3r as the carriage Y travels. It is equipped with. Left and right switch mechanism G
e and Gr have substantially the same structure, although the mutual arrangement of the 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. Place the part on the base plate 4
The crank 53 is connected to the lever of the microswitch 56 mounted above, and as the carriage Y travels, the protrusion 55 passes through the cam groove 31 of the left or right switch activation pieces 3e and 3r, and the crank 53 is activated. The microswitch 56 is rotated to switch the microswitch 56. That is,
Micro switch 56 for left and right switch mechanisms Gf and Gr
, 56 are both turned on when the respective corresponding protrusions 55, 55 are within the distance between the left and right switch actuating pieces 3', 3r, and are turned off when they move outside this distance. be. The left and right protrusions 55, 55 are located at the selection implementation points of the left and right knitting needle sorting mechanisms F' and Fr, respectively, that is, on the rear extension line of the t-width portion, and are located on the left and right switch mechanisms. G', Gr are
When the sorting points of the left and right knitting needle sorting mechanisms F' and Fr approach the installation positions of the switch activation pieces 3' and 3r on the needle bed x, the switches operate, respectively, as shown in Fig. 18 [■] [■] As shown in RH. It is designed to output an electrical signal that is inverted from J to RLJ or vice versa,
Moreover, the electric signals of these two switch mechanisms G' and Gr are transmitted to the effective needle selection range indicating switch part of the microswitch e of the carriage reversal switch mechanism E. By this, only the one on the side where the effective needle selection operation is performed is taken out.

Therefore, as shown in Fig. 18 [■], the effective needle selection range indicating switch section E3 is turned off after the needle selection end detection switch mechanism G' or Gr on the side that performs effective needle selection is switched on. In other words, while the needle selection point of the knitting needle selection mechanism Fe or Fr on the front side in the traveling direction of the carriage Y is within the interval between the left and right switch activation pieces 3e and 3r, a signal indicating the effective needle selection range is activated. RHJ, and outputs a signal RLJ when the interval is outside the above interval range.
During output, the above-mentioned memory storing digital electrical signals related to the knitting pattern is read out, and only during this time the electromagnet 46 on the side that performs the effective needle selection operation is energized.
It is now subject to de-energization control.

In this way, reading of the memory is performed only within the effective needle selection range determined by the left and right switch activation pieces 31) and 3r, but the reading is performed when the traveling speed of the carriage Y is not constant and fluctuates greatly. Therefore, it must be done in accordance with the travel timing of the carriage Y.

Therefore, the rear end of the carriage Y on the base plate 4 is connected to the left and right knitting needle sorting mechanisms Fl, Fr. Photoelectric sensors He, Hr are installed at corresponding positions, and the photoelectric sensors Hl, Hr are attached to the upright wall X1 at the rear end of the needle bed x in the needle groove. The slits ■...... arranged in a one-to-one relationship are used as a kind of linear encoder; by reading them as the carriage Y travels, the photoelectric sensors He, Hr 1st
As shown in Fig. 8 [1], 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. Hereinafter, the photoelectric sensors He and Hr will be referred to as timing pulse generators.

It should be noted that the pulses from the left and right timing pulse generators He, 7 are valid only for those corresponding to the knitting needle selection mechanism F' or Fr on the side that performs effective needle selection operation by the carriage reversal switch mechanism E. It is starting to be taken out.

The mechanical configuration of the hand knitting machine is as described above, and next, its electrical and electronic configuration will be explained. First, an outline of the configuration of an input function section that scans and feeds the card 1 and stores the read knitting pattern in the memory MEM as a digital electrical signal will be explained with reference to FIG. The electric signal related to the card scanning of the scanning sensor c is generated by the effective scanning data forming circuit C and is related to the rightward stroke of the scanning member b from the original position, which is the left stroke end, to the reversed position, which is the right stroke end. Only the number of needle selection units is taken out as valid, and the card feeding and scanning instruction circuit CSl needle selection unit number setting circuit NSl
It is designed to be input to the memory control circuit ``MC1 function discrimination circuit FS.

The card feeding and scanning instruction circuit CS is configured to receive an electric signal when the left limit switch 33e, which is a scanning member original position detection means, is turned on, and the instruction circuit CS receives an electric signal when the scanning member b is the original position. 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 RH or RL, that is, whether the display on the card 1 is a mark or no mark. An electric signal corresponding to the judgment result is supplied to the card feeding and scanning control circuit βC, and thereby the control circuit SC controls the card feeding drive circuit CD according to the mark or no mark to feed the card. the electromagnet 16 of
Alternatively, the card 16'' is driven, whereby the card 1 is automatically transferred by the distance between the search mark 36, feed control mark 34, etc. displayed thereon.

Further, the instruction circuit CS 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 CS
When the needle enters from outside the effective needle selection range divided by the left and right switch activation pieces 3e and 3r, an instruction signal for starting the movement of the scanning member b is input to the control circuit μSC. In addition, the control circuit C is configured to receive an electric signal when the right limit switch 33r, which is a scanning member reversal position detecting means, is turned on, thereby causing the control circuit μSC to drive the scanning member. The rotational speed is controlled so that the drive circuit SD also supplies sufficient current to the coil 31 of the scanning member b to enable the scanning member b to travel back and forth in one go.

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 by the effective sampling pulse forming circuit D, and inputted to the pulse separation circuit circle. Therefore, the pulse for sampling the search mark 36 on the card 1, the pulse for sampling the knitting pattern, and the pulse for sampling the function mark are separated from each other, and here, the pulse for sampling the knitting electric signal 36 is separated from each other. The number of pulses (total of 12 fences) for this purpose is thinned out by 2 for each scribe grid when using card 1 with the number of rows of the scribe grid in knitting pattern entry column 1 being R36 as described above. The pulses that have been removed and left behind 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 needle selection unit number setting circuit NS. Four pulses for sampling the function mark are respectively input to the function discrimination circuit FS. The needle selection unit number setting circuit NS samples the electric signal related to the reading of the search mark 36 from the effective scanning data forming circuit C by the input one pulse, and determines the number of needle selection units. This is an instruction to electrically preset the number of needle selection units, which is the sampling mode of the mark in the number setting column L.
Further, the setting circuit NS is inputted with the pulses before thinning for sampling the knitting pattern from the pulse separation circuit circle, and at which pulse, the effective scanning data forming circuit C selects the number of needle units. Setting field 1
, depending on whether the electrical signal related to reading the mark is input, the number of needle selection units programmed in the needle selection unit number setting field 1s is memorized by a digital electrical signal, that is, the number of needle selection units is electrically preset. It's getting old. 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, when the number of needle selection units is between R6J and R36J, the pulse separation circuit PS is controlled to thin out two needles at a time as described above. Upon receiving the instruction to electrically preset the number of needle selection units as described above, the scanning member b controls the card feeding and scanning instruction circuit CS and the card feeding and scanning control circuit SC to set the number of needle selection units. After scanning column L once and returning to the original position, card 1 is automatically transported until scanning member b reads the lowest mark among the feed control marks 34. It's starting to work.

The write address designation circuit WA includes a binary counter that counts the pulses inputted from the pulse separation circuit circle as described above, and writes a write address designation signal to the memory control circuit MC by sending a parallel binary electric signal according to the counting result. 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 circle 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 samples it for each knitting needle and each bit. After correspondingly converting it into a digital electrical signal (see FIG. 13 [X■]), the digital electrical signal is sequentially sent to a certain predetermined location in the memory MEM under the addressing control of the write address designating circuit WA. The address and also an electric signal corresponding to the carriage running direction from the carriage running direction detection switch section G are used to separate the left-hand scanning and right-hand scanning of the carriage Y. The information is stored separately in the storage unit, that is, in two storage units.

The function discrimination circuit FS converts the electric signal related to the function mark scanning from the effective scanning data forming circuit C into each of the function mark entry fields 1f using the four pulses inputted from the pulse separation circuit circle as described above. Sampling is performed for each reporter grid row, and the sampling of the two columns on the left side of the reporter grid row is input to the card feeding and scanning control circuit SC, and the card 1 is sent to it in the forward direction or in the reverse direction. control the right side 2 again.
Items related to column sampling are input to a function drive circuit FD, which controls necessary function operations such as thread exchange operations.

Further, the card feeding and scanning instruction circuit CS, control circuit ℃, and 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. By operating the button, the card 1 can be moved by one step in the direction opposite to the direction of transfer before the button operation, and the data currently stored in the memory MEM can be cleared. This makes it easier to re-knit in case of incorrect knitting.

Further, the card feeding and scanning control circuit SC is controlled by operating another manual operating means, that is, a stop button SB, which is also provided on the operation panel 2, and the card 1 is transferred by operating the stop button SB. It is made so that it can be stopped. Furthermore, when performing a special formation, by operating the special function button W also provided on the operation panel 2, the card feeding and scanning instruction circuit CS is controlled, and the card feeding and scanning perform special operations. I'm starting to be able to do it.

Next, the specific configurations of the effective scanning data forming circuit C1 effective sampling pulse forming circuit D1 pulse separating circuit PS, needle selection unit number setting circuit NS and function discrimination circuit FS will be explained with reference to FIGS. 12 and 13. R-
The S flip-flop 60 is set by the left limit switch 33e, which is a scanning member original position detection means, and reset by the right limit switch 33r, which is a scanning member reversal position detection means, so that the scanning member b is reversed from its original position. The AND gates 61c and 61d are opened only during the outgoing process of traveling to the 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 enabled. The output signal of the sampling pulse forming circuit D is outputted from the AND gates 61c and 61d (see Fig. 13 [■], [■], and [1]).
.

As shown in FIG. 13 [■], the output of the limit switch 33e becomes RHJ when the scanning member b moves away from the original position at RLJ. An R-S flip-flop 62 for separating 36 sampling pulses,
It is set when the scanning member b leaves the original position, and is reset by the fall of the first pulse (pulse for sampling the search mark 36) from the effective sampling pulse forming circuit D. .

The output of Q of this flip-flop 62 opens the AND gate 63 which receives the pulse from the effective sampling pulse forming circuit D. Thus, pulses other than the pulses for sampling the search 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 D are both RHJ, that is, when the search mark 36 on the scanning sensor code 1 and the selection unit number setting field L (scanning along the P1-P1 line in FIG. 13, [V] in the same figure is the output waveform of the effective scanning data forming circuit C at that time), the sampling sensor d detects the search result of the linear encoder 37. Mark sampling slit 38,
When detected, one pulse is output as shown in [■].

Therefore, this pulse output from the AND 64 indicates that the search mark 36 has been detected. The output of this AND64 (actually it is the knot 6C
R-S flip-flop 6 for storing that the search mark 36 has been detected.
5 is now set.

This flip-flop 65 is reset by the output of AND66. AND66 has flip-flop 6
5, 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 D.
In Fig. 13, these outputs are [■], [■],
If you compare [■] and [■], it is clear that all of them are RH.
In other words, after the search mark 36 has been detected as described above, when the mark placed in the needle selection unit number setting field L is detected, one A pulse is output, and the flip-flop 65 is reset by this pulse.

Therefore, the flip-flop 65 stores the detection of the search mark 36 as shown in [■] only until the mark in the needle selection unit number setting column 1 is detected.

In addition, the above-mentioned one pulse also controls the above-mentioned card feeding and scanning instruction circuit CSl and control circuit SC as will be described later. On the other hand, the pulse [■] from the AND gate 63 from which the pulse for sampling the search mark 36 has been removed as described above is the hexadecimal -
The pulses [■] are counted by a binary counter 67, more specifically, a hexadecimal counter that directly counts the pulses [■], and a binary counter that converts the count value of the hexadecimal counter into a binary number and counts the pulses [■]. ] The count value of the counter 67 is incremented by one each time 6 pieces of .

The count value of this counter 67 is the output of the above AND 66 [
■] When the mark in the needle selection unit number setting field L is detected by the gate network 68 which uses the gate operation signal as the gate operation signal, the memory 69
The data is written into the memory 69, and is subsequently stored in the memory 69.

This memory 69 stores the output of the flip-flop 65 [■
], that is, when the search mark 36 is sampled.

Further, the count output of the counter 67 is
Whether the number of pulses [■] from 3 is within 120 or 12
It is input to a gate network 70 that discriminates whether the number is 1 or more.

This gate network 70 performs the above discrimination on the parallel output from the counter 67 using a logic circuit formed by a combination of gates, and if it is within the above 120, the output terminal of AND gate 711 produces an output
If Rl2lJ or more, an output is generated from the output terminal of R2J and the AND gate 712 is opened. Therefore, [M] than AND gate 711
12 for sampling of knitting patterns as shown in
The fence pulse is output, and the AND gate 712 outputs four pulses for sampling the function mark as shown in [■].

The 12 pulses from the AND gate 711 are input to a pulse selection circuit 72, where they are divided into three types of pulses.

That is, in the pulse selection circuit 72, the output system of RlJ is designed to pass the above-mentioned 120SI pulse as is, as shown in [■], and the output system of R2J is configured to connect a T-type flip-flop and this output side. As shown in [x■], it thins out the even-numbered pulses of the 12 pulses and outputs the rest, and the output system of R3 is , includes a ternary counter and an AND gate connected to this output side, and as shown in [XV], among the 1-node pulses, the pulse minus 1 (where n is an integer) is left out and the others are They are starting to thin out. On the other hand, as mentioned above, the output of the memory 69 which stores the number of needle selection units programmed in the number of needle selection units setting field L in the card 1 is the output of the above three types output from the pulse selection circuit 72. It is input to a gate network 73 for selecting which of the pulses is actually used as a sampling pulse, and the number of needle selection units is 6 to 6.
36, R3.36 of the gate network 73. An output is generated from the output system of J, the AND gate 743 is opened, and the [XV] pulse of the above three types of pulses passes through the OR 75, and if it is between 42 and 60, R2
An output is generated from the output system of J, the AND gate 742 is opened, and the pulse of [x■] passes through the OR 75. Furthermore, if it is between Seki and 120, an output is generated from the output system of RL. As a result, the AND gate 741 opens and the pulse of [x■] passes through the OR 75.

The reason why the sampling pulses for sampling knitting patterns are divided into three types and are selectively taken out depending on the number of needle selection units is because the main hand knitting machine is
As shown in the figure, the number of grid rows in the knitting pattern entry field h is 36, and the number of needle selection units is 6, 12, 18, 24, 30,
In addition to the card that can be selected as 36, as shown in Figure 19, the number of grid rows is 60 and the number of needle selection units is 42, 48.
, 54, and 60, and as shown in Figure 20, the number of grid rows is 120 and the number of needle selection units is 66,
72, 78, 84, 90, 9 snakes 102, 108, 114
, 120 cards, a total of three cards, are used depending on the number of needle selection units.

Incidentally, when the card 1 shown in FIG. 2 is used, the pulses output from the OR 75 are a total of four pulses shown in FIG. 18 [x■], which are explained in FIG. is input to the memory control circuit MC and the write address designation circuit WA, thereby causing the output of the valid scanning data circuit C (when the scanning sensor c scans the card 1 along the line P2-P2 in FIG. The output at the time is shown in [■]), and the output related to the scanning of the knitting pattern entry field 1p is shown in [X].
After being converted into a digital electric signal corresponding to the knitting needle in a one-to-one relationship as shown in [X], a certain fixed state of the memory MEM is determined by the addressing operation of the write address designation circuit WA shown in [X■]. The data is stored sequentially according to the assigned address.

The storage of digital electrical signals in the memory MEM is performed for all signals from the left edge to the right edge of the first row of the register grid in the knitting pattern entry field h as described above, but the readout is performed only when the selection is made. This is repeated only for the number of needle selection units set in the number of needle unit setting field L. In order to do this, the hexadecimal-binary number in the memory 69 that stores the number of needle selection units set above is The output 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.

On the other hand, the four pulses [■] for function mark sampling output from the AND gate 12 are separated from each other by a pulse discrimination circuit 77 composed of a group of gates.

That is, the four pulses are counted by the counter 78, and the decoder 79 outputs R as shown in [X■] and [x■] according to the number of pulses.
An output is generated from the output system of RlJ-R4 and opens the gates in the pulse discrimination circuit 77, so that the output system of RlJ-R4J of the pulse discrimination circuit 77 becomes [XX],
As shown in [x■], outputs are produced sequentially in accordance with the order of the pulses. The four pulses separated by the pulse discrimination circuit 77 are input to a function memory circuit 80 composed of a D-type flip-flop, etc., and the output [■] from the effective scanning data forming circuit C is sampled here. is performed for each reporter grid in the function mark entry field 1f, and the sampled data is stored separately for each reporter grid column as shown in [XXII].

Then, RlJ-R of this function storage circuit 80
The output of RLJ2J of the four output systems in section 4 is input to the aforementioned card feeding and scanning control circuit SC, which will be explained in detail later, and the output of RlJ controls the forward feeding of card 1. , and the output of R2J is designed to control reverse direction feeding, and the outputs of R3J and r4J are input to the aforementioned function drive circuit FD to respectively control required function operations other than card feeding. It's getting old. Next, we will discuss the specific configuration of the card feeding and scanning instruction circuit CS and the control circuit μSC in the first section.
This will be explained with reference to FIGS. 4 to 16. Clear button CB mentioned above
In addition to being used in case of incorrect organization as mentioned above, it also serves as a kind of start button to start the organization when starting the organization using card 1. Before explaining the operation, an outline of how to use the hand knitting machine will be explained.

First, perform necessary knitting such as waste knitting by operating the carriage in the usual manner, and when knitting is completed to the point where a pattern is to be added, the carriage Y is set to the left and right of the knitting needle group set at the needle selection receiving position on the needle bed x. It is stopped outside one end. In this state, the card 1 is fed manually, that is, by turning the ratchet wheel 14 by hand, so that the upper and lower middle portions of the search marks 36 face the scanning sensor c of the scanning member b, which is in its original position. Set it where you want it.

After that, press the above clear button CB, card 1
is transferred by one pitch in the forward or reverse direction (the direction at this time is not determined as will be described later), and then the scanning member b is moved, for example, along the line P1-P1 shown in FIG. During the forward movement, after the number of needle selection units is set as described above, the forward movement of the card 1 is restarted at the end of the forward movement. This transfer continues intermittently until the lowermost feed control mark 34 is detected by the scanning sensor c, and upon that detection, it is stopped and the scanning member b is immediately moved.
travels back and forth along the line P2-P2 in FIG. 13, and when it returns to its original position, the series of operations by operating the clear button CB ends. After that, 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 3' and 3r 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 the clear button CB is operated, the accompanying signal (Fig. 15 [1)] is inverted at knot 81, passes through or 82, and then is inverted again at knot 8 [■], instructing card feeding and scanning. The signal is output from the circuit CS as a card feed and scanning instruction signal, and is configured to set an R-S flip-flop 83 for instructing card feeding and an R-S flip-flop 84 for instructing scanning member forward movement in the control circuit μSC. .

By setting the flip-flop 83, the Q output [■]
is applied to a card feed drive circuit 86 consisting of a gate network through an AND 85, and either one of the output terminals of RL on the forward sending side or R2 on the reverse sending side of this control circuit 86, e.g. One pulse shown at [v] is generated from the output terminal of R2, and the aforementioned card feed drive circuit CD is driven.
Either one of the pair of electromagnets 16,1' is operated to transport the card 1 either in the forward direction or in the reverse direction.

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 b are opposed to the scanning sensor c of the scanning member b, scanning is performed by one predetermined pitch. That is, the card feed drive control circuit 86 drives the card feed drive circuit CD using an output pulse from a timer 87 that determines the amount of feed for one pitch of the card 1, and the output pulse is of a D type. The signal is input to the T terminal of the flip-flop 88, and the flip-flop 83 is reset by the rise of the Q output [■] of the flip-flop 88.

Further, the output of the effective scanning data forming circuit C is inputted to the D terminal of the D-type flip-flop 88, and the flip-flop is connected to the right limit switch which is the scanning member reversal position detection means. 33r
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 counted for a predetermined period of time. In addition, the counter is reset by the RLJ output [■] of the flip-flop 83. Therefore, the D type flip-flop 88 has a D terminal 1.
The input is sampled and output by the rising edge of the input pulse of the T terminal, and when the clear button CB is operated as described above, the timer 87 operates and outputs one pulse, and the card 1 When only one pitch is sent, the search mark 36 does not exceed the scanning line of the Canning sensor C either above or below, so the mark is detected by the valid scanning data forming circuit C at the D terminal of the flip-flop 88. RH indicates that
J output is input, and the flip-flop 83 is reset by the output of the flip-flop 878.

Therefore, the timer 87 stops operating after outputting only one pulse, and the card 1 is only fed by one pitch. By the way, when the R-S flip-flop a knob 89 that operates the clear button CB is set, during the set time, that is, until it is reset by the right limit switch 33r, the feed direction reversal circuit 90 is activated by its output.
is controlled to switch the output operation of the card feed drive control circuit 86 so that the card 1 is transferred in the opposite direction. When you operate
Since it is not determined whether the R-S flip-flop 91, which indicates the direction in which the card 1 is to be transported, is in a set state or a reset state, it has not been determined in which direction the card 1 is to be transported by one pitch.

When the transfer of only one pitch is completed, the scanning member b
moves back and forth. 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 the signal obtained by inverting the Q output of the flip-flop 83 with the knot 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 circuit. μSD
There is no need to drive the scanning member b to move it forward.
Move card l forward only when it is stopped.
This forward movement ends when the flip-flop 84 is reset by the right limit switch 33r, as shown in FIG. is set, the scanning member b immediately begins to move backward.

In this backward movement, the scanning member b is connected to the limit switch 33 on the left side.
The scanning member b collides with the limit switch 33e at a considerable speed, and the reaction causes the limit switch 33 to close.
1) may chattering as shown in FIG.
The home position return signal from 3e is delayed as shown in FIG. 16 [X■] and resets the flip-flop 94 as shown in FIG. is designed to apply a force that causes the stroke to move further to the left even after reaching the left stroke end, thereby preventing the above-mentioned fear from occurring.

As described above, when the scanning member b reciprocates by operating the rear button CBf), during the forward movement, the number of needle selection units setting circuit NS selects the number of needle selection units entry column L as described above.
The number of selected needle units programmed in the unit is electrically set, and when the setting is done, one pulse ( The R-S flip-flop 96 in the card feeding and scanning instruction circuit CS is set by FIG. 15 [■]), and its Q output (FIG. 15 [■]) is
, the card feeding flip-flop 83 is set again via the knot 82'' [■].

However, the card feed drive control circuit 86 is configured such that the signal from the left limit switch 33e can be inputted through the knot 97, and the card feed drive control circuit CD is activated only when the scanning member b is in the original position. Therefore, the card 1 will not be transferred while the scanning member b is running after the number of needle selection units is set. When the scanning member b returns to its original position, since the flip-flop 83 has already been set as described above, the pulse signal of the timer 87 is input to the card feeding drive control circuit 86, and the card 1 is transferred.

At this time, the transfer direction is determined by the one pulse from the needle selection unit number setting circuit NS setting the flip-flop 91 which instructs the card feeding direction via the OR 98, and reset by operating the clear button CB. Since the flip-flop 89, which had been in the The pulse is output from the output terminal as shown in [■], so it is in the forward direction.

The feed direction reversing circuit 90 is composed of two exclusive OR circuits, and when the output of the flip-flop 89 is RLJ, the input from the flip-flop 91 is directly input to the control circuit 86, and conversely, the output is At the time of RHJ, the above-mentioned input is inverted, and furthermore, the flip-flop 91 instructs forward feeding of the card 1 by turning its Q output to RH at the time of setting, and its O output at the time of reset. The output is RHJ, which instructs reverse direction feeding.
Thus, 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 [■] of the D-type flip-flop 88 is used to transfer the card 1 by one pitch. The card feeding 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 receives the output [x] of the AND 99 (the AND Since it is not reset (reset by a falling edge) by the output of the effective scanning data forming circuit C which has passed through, the set state is still maintained, and the card 1 is continuously and repeatedly transported in the forward direction intermittently. 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. The input to the D terminal of the D-type flip-flop 88 (output of the effective scanning data forming circuit C) also corresponds to the no mark.
As shown in [], the output of the D-type flip-flop 88 does not reset the flip-flop 83, and the flip-flop 83 still maintains the set state.
The card 1 continues to be transported in the forward direction even in the unmarked 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 subsequent forward movement, the D-type flip-flop 88 resets the flip-flop 83. ,
Transfer of card 1 is stopped.

At the same time, the Q output [x■] of the scanning member forward movement flip-flop 84, which has been set by operating the clear button CB as described above, is reset via the AND 92 by resetting the flip-flop 83. is inputted to the scanning member drive circuit SD, the scanning member b reciprocates and the scanning sensor c moves the card 1.
is scanned along the line P2-P2 in FIG. finish. Note that the digital electrical signal (Fig. 13 [x■]) representing the knitting pattern obtained by the first one-stage scanning is limited to the memory ME.
It is designed to be written into both of the two storage units of M at the same time, but its configuration is not shown. The first scanning of the knitting pattern entry field 1p and the function mark entry field h 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 reverses its travel, the carriage travel direction detection switch part e in the carriage reversal switch mechanism E
1 (Fig. 16 [1)) is reversed from RHJ to RLJ or vice versa, and this reversal is detected by the carriage reversal detection circuit 100 including a knot, two differentiating circuits, and a Noah. Thereafter, the signal shown in FIG. 16 (■) 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 actuating pieces 3e and 3r by traveling after this reversal, the output of the effective needle selection range indicating switch section is activated as described above. As shown in Fig. 16 [■], the signal RHJ is obtained, so the AND 102, which receives this output and the Q output [■] of the flip-flop 101, outputs the signal RHJ as shown in [v]. After the signal passes through the orer 82 and is inverted at knot 82'' as shown in [■],
The card feed and scan instruction signal is output from the card feed and scan instruction circuit CS, and the flip-flops 83 and 84 in the control circuit SC are set as shown in [■] and [x■]. .

By the way, since the output of knot 82'' is also used as a reset signal for the flip-flop 101,
At the moment when the output of knot 82'' occurs, flip-flop 1
01 will be reset, resulting in AND10
2. The output of the knot 82' becomes a trigger waveform as shown in [■] and [■].

By setting the flip-flop 83, the pulse [■] from the timer 87 passes through the output terminal of RlJ of the card feed drive control circuit 86 as shown in [■], similar to the case of operating the clear button CB described above. The first pulse [■] is input to the feed drive circuit CD and is sent in the forward direction by one pitch.
By this one pitch transfer, the feed control mark 3
4 is removed from the scanning sensor c, the output [■] of the effective scanning data forming circuit C corresponds to the no mark, and the D-type flip-flop 88 does not reset the flip-flop 83, but the timer 8
7 outputs the next pulse, and the card 1 is further moved 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, and instead of the card 1 already set. Q output of flip-flop 84 for instructing scanning member forward movement [
■l] is input to the scanning member drive circuit SD through the AND 92 as shown in When the switch is turned on, the output [XV] resets the flip-flop 84.
Instead, the flip-flop 94 for instructing the scanning member to move back is set, so that the scanning member b moves back and reaches the original position. Stop at , and complete one-stage scanning of card 1. In this way, move the carriage Y to the left and right switch activation pieces 3.
Every time the card 1 is moved leftward or rightward from outside the range of e, 3r to within the range, the card 1 moves to the feed control mark 34...
automatically transferred by the interval length of - with 1
Each stage is scanned by the scanning sensor c. Note that the output of RlJ of the function storage circuit 80 in the function discrimination circuit FS (when a mark is applied to the leftmost mark grid row among the four mark grid rows in the function mark entry field 1f) The output of R2J (output of R2J) is configured to set the flip-flop 91 for instructing the feeding direction via the OR 98, and the output of R2J (the second register grid row from the left edge is marked). The output (output when the card was in progress) is reset, and card 1 can be sent forward in the j direction or in the reverse direction by marking any of the above two grid grids. It is possible to arbitrarily control whether the

Further, when the above-mentioned stop button SB is operated, the card feed drive control circuit 86 is reset.
Even if the carriage Y is moved back and forth as described above, the card 1 is not transferred, and only the scanning member b 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 repeatedly knit a continuous pattern. Furthermore, the AND 102 generates the output shown in FIG. 16 [V] when the special function button W is not operated, and as a result, the feed and scan are performed until the carriage Y is within the effective needle selection range. It is designed to work the same way whether you enter from the left or right direction, but if you operate button W, the carriage Y
Only when the needle is reversed from the left row to the right row and enters the effective needle selection range from the right side, an output is generated from another AND 103, and card feeding and scanning are performed only at that time. It is something.

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 1 can be transferred by one step in the opposite direction,
This is clear from the above.

The input function section described above transfers and scans the card 1, and enters the knitting pattern 1! l! The knitting pattern drawn in 119 is sequentially read row by row and stored in the memory MEM as a digital electrical signal corresponding to the knitting needles N in a one-to-one relationship. an output function part that causes the left and right knitting needle selection mechanisms Ff and Fr to select knitting needles N by reading out digital electric signals stored in the memory in accordance with the travel timing of the carriage Y while the carriage Y is traveling within an effective needle selection range; This will be explained with reference to FIGS. 17 and 18.

When the carriage Y enters the effective needle selection range and the effective needle selection range indicating switch section E3 of the carriage reversal switch mechanism E outputs the signal RHJ as shown in FIG. 18 [■] while traveling in the effective needle selection range. , the read address designating circuit RA is in the set state only during the output thereof. This read address designation circuit RA includes an up/down counter, and is configured to count timing pulses [1] input from the timing pulse generators He, Hr every time the carriage Y travels one pitch of the knitting needle. However, the counted value can be determined by inputting a parallel binary signal (specifically, the output of the code converter 76 shown in FIG. 12) indicating the number of needle selection units from the needle selection unit number setting circuit NS. card 1
The number of needle selection units is preset to be the same as the number of needle selection units (12 in this example) programmed in the number of needle selection units entry column L of , and the switching of addition/subtraction is controlled by the carriage traveling direction detection switch section e1. A signal representing the direction in which the carriage is traveling [This was traditionally done, and the timing pulse was added or subtracted depending on the direction in which the carriage was traveling.

In this way, the read address designating circuit RA counts the preset number of timing pulses while the carriage Y is traveling within the effective needle selection range.
The same value (parallel binary electrical signal) will be taken repeatedly as shown in .

In other words, it can be said that this circuit RA encodes the knitting needles N between the left and right switch activation pieces 3e and 3r, and assigns repeat numbers to them in a certain direction. The output of this circuit RA is supplied to the memory control circuit MC as a read address designation signal for the memory MEM, and the signal [V] representing the carriage running direction is supplied to the memory control circuit MC as a read address designation signal for the memory MEM. The digital electrical signal stored in the memory MEM is input to the control circuit MC as a signal to determine which of the two storage sections of the memory MEM is to be read out. In this example, 12 bits from 0 to 11 are repeatedly read out from the storage section corresponding to the running direction, and are outputted from the memory control circuit MC as a binary electric signal as shown in [x], and the waveform is The signal is input to the processing circuit WP.

The waveform processing circuit WP is connected to the effective needle selection range indication switch E.
The signal [■] from the memory control circuit MC is input to the electromagnet drive circuit MD only during the RH operation, and the above signal from the memory control circuit MC is treated as valid and supplied to the electromagnet drive circuit MD. The output is determined by the electromagnet changeover switch E2 from the electromagnet 46 of the knitting needle sorting mechanism F' or Fr on the side that performs the effective sorting operation.
It is now entered into .

In this way, the knitting needles N between the left and right switch activation pieces 31 and 3r are as shown in [■], with 12* in one group.
Sorting is done according to the form of the knitting pattern drawn between the leftmost grid and the 12 grids on the right side of the knitting pattern entry field 1p (for example, in Fig. , the filled-in area is the backward deflection, and the oval shown by the broken line is at the rest position where it is not subjected to needle selection action).

By the way, as mentioned above, the knitting pattern entry column 19 is scanned over the entire length of its left and right ends, and all bits of the digital electrical signal obtained by the one-stage scanning are stored in the memory MEM. The number of bits read from it is determined by the number of needle selection units programmed by marking the number of needle selection units entry column L.
For example, if it is Rl2J, even if the knitting pattern is recorded further to the right of the 12th reporter grid from the left in knitting pattern entry field b, the recorded part on the right side will not be scanned. 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 further changes the knitting pattern and changes the form of the pattern to be actually knitted. , which can be changed using the manual operation member on the operation panel 2 mentioned above,
Next, I will explain about it.

The left/right pattern selection means RL changes the output electric signal to RH as shown in FIG.
The signal is inverted from J to RLJ or vice versa as shown by [x■], and that signal is compared with the signal [■] representing the carriage running direction in the comparison circuit CO (exclusive OR). ), and the read address designation circuit RA is controlled by the comparison signal [■].
The direction of addition/subtraction of the up/down counter is specified.

Therefore, the count value of the read addressing circuit RA is
It is determined based on the operation of the pattern left/right selection means RL whether the carriage Y travels in a certain direction in the above-mentioned relationship [■] or in the relationship [XV].
Even if the knitting pattern on card 1 is the same, the knitted patterns in [■] and [x■] have a relationship as if the left and right sides were reversed.

Next, the pattern mode selection means MS outputs an electric signal inverted from RL to RHJ or vice versa as shown in [■] by switching its manual operation section, and sends it to the waveform processing circuit WP. This means MS
By this operation, the waveform processing circuit WP determines whether to pass the input [x] from the memory control MC as it is without inverting it, or to invert it as shown in [■].

Therefore, by operating this means MS, the knitting needles. The front and rear sorting manner of N can be reversed, thereby making it possible to reverse the ground pattern of the pattern to be knitted without changing the knitting pattern on the card 1.

Further, the memory control MC that operates the clear button CB clears the stored contents of the memory MEM.

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

4. That is, in the above embodiment, the slit 38p for sampling the knitting pattern and the slit 38f for sampling the function mark are formed on the same plate. The two types of linear encoders, a linear encoder for sampling knitting patterns and a linear encoder for sampling function marks, were integrated.
Even if the 8f is provided separately on two separate plates and the above two types of linear encoders are made separate from each other and arranged on the same straight line, it is substantially the same as the above embodiment. It is. In addition, although the above-mentioned linear encoder is a plate with noslits, it is also possible to use a plate with bright and dark stripes formed on the surface of the plate.

Further, in the above embodiment, the coil 3 of the scanning member b
1 is fitted into the guide rod 28, and by passing currents of opposite polarities through them. In this case, the permanent magnet 32 is used as a stator to apply magnetic forces in opposite directions to the left and right sides of the coil 31, thereby causing the scanning member b to reciprocate. In addition, even if the guide rod 28 is made of magnetic material so that current is passed through the two coils alternately, and a magnetic force is generated between the coil and the guide rod 28, the scanning member b 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 b, and at the same time functions as a stator of the linear motor. Further, in the above description, the card 1 is driven by the electromagnets 16, 16'', but a pulse motor may also be used.

Furthermore, in the above, a card in which one reporter grid corresponds to one stitch is used as the knitting program card 1, but a card in which one reporter grid corresponds to a predetermined plurality of stitches may be used. Further, a card on which a knitting 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.

As is clear from the above description, the knitting information reading device of the present invention includes a knitting pattern information recording section (knitting pattern entry column 1p in the embodiment) for recording knitting pattern information representing a pattern to be knitted, and a yarn A composition information recording medium having a composition function information recording section (function mark entry f!!41f in the embodiment) for recording composition function information representing composition operation matters such as replacement can be loaded, and the composition can be recorded in the loaded state. a recording medium transport mechanism capable of transporting the information recording medium in a required direction; and the knitting pattern information recording section and the knitting function information recording section along a line perpendicular to the transporting direction of the knitting information recording medium loaded therein. a scanning sensor capable of reading both of the above-mentioned information recorded thereon as an electrical signal by scanning over the area; a first linear encoder provided, a second linear encoder also provided on the predetermined line corresponding to the composition function information recording section, and a second linear encoder that is movable integrally with the scanning sensor; scans the knitting pattern information recording section, reads the first linear encoder and generates a sampling pulse for sampling an electrical signal related to scanning of the knitting pattern, and the scanning sensor scans the knitting pattern information recording section. and a sampling sensor that reads the second linear encoder when scanning the information recording section and generates a sampling pulse for sampling an electrical signal related to the scanning of the organization function information, Since knitting pattern information and knitting function information can each be read as digital electrical signals, special care is not required to record the knitting pattern information, and since the knitting pattern information is read as digital electrical signals, it is possible to read the knitting pattern information as digital electrical signals. This makes it possible to very easily perform various operations that were previously impossible to perform.

In addition, on the same recording medium that records the pattern to be knitted, function information indicating required functional operations such as thread exchange, feeding condition of the recording medium, and start or end of needle selection operation is recorded. By doing so, the function information can be read in the same way as reading the above-mentioned pattern, and the required function operation that has been recorded and programmed on the recording medium in advance can be performed in accordance with the above-mentioned pattern. This can be done at any desired point in time relative to the needle movement. Furthermore, the linear encoder for sampling the knitting pattern information and the linear encoder for sampling the knitting function information are arranged on the same line and are read by the same sampling sensor. It has the advantage of being simpler in configuration and cheaper than those that are read using other sensors.
