Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides knitting information such as knitting pattern information representing how information is recorded on a card or the like, or knitting function information representing knitting operation matters such as thread exchange, in a knitting machine.
The present invention relates to a composition information scanning device that reads electrical signals by scanning with a scanning member.

Conventionally, as this type of scanning device, the
The one described in Publication No. 6 is known. However, in this method, the scanning member is always moved in synchronization with the sliding movement of the carriage, and when the sliding direction of the carriage is reversed, an electromagnetic switch device is turned on to transfer the pattern (information recording medium) by one stage. However, when the carriage moves from side to side (this happens often with hand knitting machines), the same reading is emphasized and the pattern is transferred unintentionally. The present invention allows the scanning member to automatically travel back and forth all at once without being constantly synchronized with the sliding movement of the carriage, that is, without being directly related to the sliding movement of the carriage, and to automatically transport the information recording medium without moving the scanning member in synchronization with the sliding movement of the carriage. The above-mentioned drawbacks are solved by associating the reversing operation with the traveling movement of the scanning member and performing it only when the scanning member has returned to its original position and is stopped.

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

Referring to FIG. 1 for an overall outline of a hand knitting machine to which the present invention is applied, the knitting machine main body X having a needle bed A scanning device A according to an embodiment of the present invention is loaded with a scanning member (not shown in FIG. 1) that optically scans information, and is used to manually operate various mechanisms described below in addition to this scanning device A. A control box B containing various electric and electronic circuits, which will be described later, is installed on the operation panel 2 and is installed behind the needle bed x. Left and right needle selection range setting switch activation pieces 3e and 3r, which can arbitrarily divide the needle execution range, 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 x. Although not shown in FIG. 1, the knitting needles are arranged in rows on the needle bed X in response to an electrical signal obtained by scanning the knitting pattern on the knitting program card 1, using electromagnetic force. A pair of left and right knitting needle sorting mechanisms, one of which operates effectively in the forward and backward direction according to the traveling direction of the carriage Y, are arranged at a predetermined length apart on the left and right sides.

In the scanning device A, the scanning member is
By automatically scanning the information recorded on the card 1 horizontally in a straight line when the running of the card is reversed, an electric signal corresponding to the information is outputted, and the subsequent processing of the electric signal is performed using an electronic configuration. Furthermore, power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms by, for example, a cord 6 that is passed through a tension member 5 that applies tension to the knitting yarn. , the carriage Y is placed on both the left and right sides of the switch activation pieces 3e and 3r. By making the knitting needles travel back and forth until they cross the edge, only the knitting needles within the interval range of the switch activation pieces 3e and 3r have an effective sorting effect (excluding those within this range that are in the rest position where they are not subjected to any sorting action at all). ).

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

The entire scanning device A is equipped on a frame 7 further behind the rising drive at the rear end of the needle bed To explain the mechanism for transferring, endless sprocket belts 8' and 8r, which serve as 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, 8r have sprockets 8'', which fit into the left and right perforations of the knitting program card 1, protruding from their outer peripheral surfaces at a constant interval, and these left and right sprocket belts 8',
8r and a card guide plate 9 with a U-shaped cross section disposed between them and below, the card 1 is inserted between the perforation 1'' and the sprocket 8''.
By fitting the sprocket belt 8e
, 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.
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 11' 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 10', 10r are connected to the drive shaft 12.
Also, the left and right small pulleys 11e 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 aforementioned transfer drive mechanism a. As this ratchet wheel 14 rotates, the left and right sprocket belts 8e, 8r
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 the plungers 17, 17'' of a pair of electromagnets 16, 167, respectively, by pins 18, 1''. The forward or reverse direction of the ratchet wheel 14 is determined depending on which of the wheels 16 and 16'' is driven.

That is, both the sending pieces 15, 15'' are always held together by their claws 21 by the springs 19, 19'' that act on them individually and the spring 20 stretched between them.
, 2" are set at the upper limit retracted position where they do not engage with the ratchet wheel 14, but the corresponding electromagnet 1
6 and 16'' are repeatedly energized and deenergized by inputting a pulse electric signal, and as the plunger 17 or 17'' moves up and down, the guide piece 22 rotates slightly, respectively.
, 23 or 22', 23'' to repeatedly engage and disengage with the ratchet wheel 14.

Therefore, depending on which of the pair of electromagnets 16 and 16'' is driven, the forward and reverse directions of the ratchet wheel 14 are determined, and thereby whether the card 1 is sent in the forward direction or not (see FIG. 2). (lower side) This determines whether to send 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 impaired. In order to prevent this, a card receiving plate 24 is provided between the left and right sprocket belts 8' and 8r, and a card receiving plate 24 is provided between the left and right sprocket belts 8' and 8r. Left and right card holding pieces 25f, 2 that lightly press the edges, respectively.
Equipped with 5r.

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.
In addition, each card holding piece 251, 25r has a fulcrum on the axis of the drive shaft 12, as shown in the side view of the right side in FIG. It can be rotated, that is, opened and closed, but the spring 26
The card 1 is biased rearward, that is, in the closing direction, by the perforations on its left and right sides as described above. sprocket belt 8', sprocket 8 of 8r
'' and is pressed by the card holding pieces 25' 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 forms a flat slope over almost the entire length on the left and right sides, and next, the card 1 is scanned horizontally in a straight line in this flat sloped portion. The traveling drive mechanism that causes the scanning member b to travel will be described.

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 able to slide 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 running body 29, slidably fitted into the upper guide rod 27.
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 thereto.

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 traveling member b automatically travels 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 and the permanent magnet 32 are
This constitutes a kind of linear motor with 2 as a stator.

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

The limit switch 33' on the left side 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. limit switch 3
It moves left and right between 3e 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's travel, it moves from its original position to the right stroke end at a fairly high speed, and as soon as it reaches the right stroke end, it immediately reverses (
The left and right limit switches 33e and 33r respectively check whether the scanning member b is at the original position or the inverted position (right stroke). There are some that also function as a means of detecting whether or not the object is at the end. As shown in FIG. 3, the upper extension part 29'' of the traveling body 29 of the scanning member b extends diagonally upward on the rear side and then diagonally downwardly, and its leading edge is on the inclined surface of the card receiving plate 24. A so-called light-receiving element is located at a close position and faces it, and at its tip consists of a reading element, that is, a light-emitting element, and a light-receiving element that receives reflected light that is reflected from the surface of the card and converts it into an electrical signal. A photoelectric sensor c is installed inside.

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

Next, card 1 will be explained with reference to Figure 2. It is semi-transparent, and the perforations 1"
On the white surface in between, a knitting pattern recording section 1p, which is a part for recording the knitting pattern, and
The function mark entry field 1f, which is the organizing function information recording area on the right side, that is, the area where the function mark is recorded, is set in a color that is the same as the emission color of the light emitting element of the scanning sensor c and that the light receiving element does not discriminate (for example, the light emitting element is red). It is created by displaying the grid dividing lines (red when using light emitting diodes) in advance using an appropriate display method such as printing, and is read by the scanning sensor c on the left side of the knitting pattern entry field 1p. A large number of feed controls 34 that can control the feed amount of the card 1 by
. . . are recorded in advance by, for example, displaying slightly thick black horizontally elongated lines at regular intervals in the direction in which the perforations 1'' are arranged.

The spaces between the entry fields 1p and 1f and between the entry field 1p and the feed control mark 34 are blank.
In the above-mentioned knitting pattern entry column 1p, the vertical lines of the grid dividing lines that constitute it are the dividing lines between stitches, and the horizontal lines are the dividing lines between knitting rows, and below the margin, The numbers representing the stitches are shown in the same color as the grid dividing lines. More specifically, knitting pattern entry field 1
In p, one minimum section, that is, a grid corresponds to one stitch, its horizontal arrangement, or row, corresponds to one knitting needle, and its vertical arrangement, or row, corresponds to a knitting row (wale). When knitting a so-called unit pattern in which n horizontal rows of stitches constitute one group, the boundary line is the vertical line on the left and the vertical line separated by n stitches to the right. Then, draw a picture (knitting pattern) corresponding to the unit pattern to be knitted with an appropriate brush such as a pencil.
This is done by using a marking tool to draw it out in black, for example, as shown in the diagram.

For example, when knitting a unit pattern of 12 stitches horizontally by selecting knitting needles for one pot as a unit, the vertical line of the left edge and the vertical line of the first pot The purpose is to draw a picture within the scope of.

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, the horizontal line of the function mark entry field 1f is on the same line as the horizontal line of the knitting pattern entry field 1p, and its vertical line is parallel to the vertical line of the knitting pattern entry field 1p (7), and the function mark The rows (vertical arrangement) of the reporter grid in the entry field 1f are aligned on the same line as those in the knitting pattern entry field 1p and have the same number, but the number of columns (horizontal arrangement) is, for example, 36 in the knitting pattern entry field 1p. However, it is now 4.

The function mark entry field 1f is used to mark (for example, fill in black) any mark grid when performing a required function operation. (vertical arrangement), the leftmost column is for programming the forward direction of card 1, and the column to the right is for programming the reverse direction of card 1, Furthermore, the other two columns are used to program necessary functional operations other than card feeding, such as thread exchange and start and end of needle selection operations.

Further, in this example, each of the feed control marks 34 displayed in advance on the left edge is positioned on an extension of the horizontal center line of each row of the reporter grid in the knitting pattern entry field 1p. As will be described later, the card 1 is automatically advanced to each stage of the reporter's grid. Furthermore, in addition to the three types of displays mentioned above, card 1 also has a selection unit number setting column 1s for programming the number of needle selection units in the same color as that below the knitting pattern entry column 1p. It is displayed.

This setting field 1s displays a required number of independent rectangular reporter grids 35 in a row at regular intervals in the horizontal direction, and each of the reporter grids is as follows: Each of them is unique for setting a fixed number of needle selection units, and the set number of units is different from each other.
The set number of units increases in a predetermined base number toward the right, and numbers representing the number of needle selection units are displayed in advance on the bottom of each grid 35 in the same color.

Regarding this example, the number of reporter grids 35 is six in total, and the first one on the left is the needle selection unit number 16j, and the following numbers are 012, 18, 24, 30, and 36J in hexadecimal. Therefore, this needle selection unit number setting field 1s is also scanned by the scanning sensor c of the scanning member b,
The number of needle selection units is determined depending on which of the marking grids 35, . . ., the marking grid is to be marked. For example, when knitting a unit pattern using 12 knitting needles, the reporter grid 35 labeled R12 may be painted black. Further, a check mark 36 is preliminarily displayed on the card 1 in order to enable effective reading of only the setting field 1s 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 having the same vertical width as the vertical width of the marker grid 35 in the setting field 1s, and its position on the card 1 is in the direction in which the marker grid 35 is arranged. On the extension line and the feed control mark 34...
..., but its width and width are longer to the right than that of the feed control mark 34...... and the knitting pattern entry field 1p. The length includes the width of the blank space between.

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),
A predetermined position within the length range of the feed control mark 34 is read by a scanning sensor c, and the scanning member b is automatically transferred according to the feed control mark 34 only when it is in the original position. In addition, the card 1 has the scanning member b in the inverted position (
When the stroke end on the right side is reached, the register grid row on the right side of the function mark entry field 1f can be read, and the range between these reading positions on both sides is It is meant to be read.

Therefore, before starting the knitting operation, the card 1 scans the needle selection unit number setting field 1s using the scanning sensor c of the scanning member b, and then returns the automatic step feed with the knitting operation. Therefore, the knitting pattern entry field 1p and the function mark entry field 1f are scanned for each stage by the same scanning sensor c, and such scanning is performed by the scanning member b in both the reciprocating and backward movements as described above. Although it depends on the process,
Of the electrical signals associated with the scanning of both the forward and backward strokes, only those associated with the forward (rightward) stroke of the scanning member b are effectively extracted, as will be described later.

By the way, as mentioned above, in the knitting pattern entry column 1p,
The knitting pattern representing the unit pattern to be knitted is drawn in a peta, and the scanning sensor c of the scanning member b scans this in a horizontal straight line for each row of the Kijin 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 1st part of the knitting pattern
It is a square wave that corresponds to the horizontal scanning mode, and if this is enough, the electrical signal obtained by scanning will not have a one-to-one correspondence with the knitting needle to be selected, and it will not be possible to write the function mark. The function mark entered in column 1f is also read by the scanning sensor c in the same way as the knitting pattern, and becomes an electrical signal in the same electrical system as in that case, and is also read by the search mark 36 that has been displayed in advance. are read in the same way and become electrical signals in the same electrical system, but these three types of electrical signals are separated from each other, and the electrical signals related to reading the knitting pattern are one-to-one with the knitting needles.
In order to read the function mark, the electric signal is also separated for each grid column (vertical arrangement) in the function mark entry field 1f. That is, the mechanical configuration of the sampling mechanism that performs 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,
It is suspended horizontally parallel to 28. Linear encoder 37
In order to sample only the search mark 36 on card l, 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 card 1. In addition to drilling 38 slits for search mark sampling,
On the right side, a predetermined number (12 in this example) of knitting pattern sampling slits 38p for sampling the knitting pattern drawn in the knitting pattern entry column 1p.
......, from the position corresponding to the left edge grid row in the knitting pattern entry field 1p, to a predetermined position beyond the right edge of the entry field 1p, spaced at regular intervals in a straight line toward the right. and further to the right,
A predetermined number (four in this example) of function mark sampling slits 38f for sampling function marks correspond in a one-to-one relationship to each reporter grid row in the function mark entry field 1f. It is perforated. On the other hand, on the rear side of the traveling body 29 of the scanning member b, there is a photoelectric sensor for optically reading the three types of slits 38s, 38p, and 38f, that is, a light emitter that illuminates the front surface of the linear encoder 37 and its reflection. A sampling sensor d consisting of a light receiving element that receives light is attached. As the scanning member b travels, the sampling sensor d detects the slits 38s, 38p,
. . . , 38f . . . It outputs a pulse, that is, a sampling pulse, according to As shown in FIG. 13, injuries related to the reciprocating stroke of the reciprocating stroke of the scanning member b are extracted as valid ones as shown in FIG. One sampling pulse for sampling the function mark 36, a 12Vi sampling pulse for sampling the knitting pattern, and four sampling pulses for sampling the function mark are separated from each other. There is. By the way, when sampling knitting patterns, 120 slits 38p are used for this purpose.
The reason for obtaining two sampling pulses is that the number of rows (horizontal arrangement) of the reporter grid in the knitting pattern entry field 1p is r.
This is to make it possible to apply a card (FIG. 20) with the number of rows Rl2O as described later, in addition to the above-mentioned card 1 having the number of columns '36'.

Therefore, for Kanido 1 whose number of columns is 136,
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, when organizing cards 1 with 036 rows, the above three sampling pulses are obtained as shown in FIG. Two of the sampling pulses are removed, and the remaining one sampling pulse samples the electrical signal associated with the scanning of one 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 Figure The digital electrical signals are stored in a predetermined memory sequentially from left to right as will be described later.

Then, the stored digital electrical signal is transferred to the carriage Y.
The information is read out sequentially and repeatedly in accordance with the travel timing of the carriage Y (7), and the needle selection mechanism (the configuration of which will be explained later) is selected from one of the pair of left and right knitting needle selection mechanisms (this configuration will be explained later) provided on the back side of the carriage Y (7). supply is becoming available.
Scanning device A, which is an embodiment of the present invention, is mechanically constructed as described above. Next, the mechanical structure of the carriage Y side will be explained with reference to FIGS. 3 and 8 to 10.

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's 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 electrical signal related to that scanning is required. In contrast to storing once in memory sequentially from left to right,
The actual needle selection operation, which is performed by reading out the digital electric signal stored in the memory, is carried out while the left and right needle selection mechanisms alternately operate in accordance with the traveling direction of the carriage Y. In order to knit the knitting pattern according to the knitting pattern drawn on card 1, the running direction of the carriage Y is detected, and the detected signal is used to store digital electrical signals in the memory and read them out. must be controlled.

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, which slide on the upper surface of the sheath frame 39, between two front and rear magnetic plates 431, 432. The two magnetic plates 431, 43.
The lower end passes through a horizontally elongated hole 4'' provided in the base plate 4 and a horizontally elongated hole 44'' provided in a slide vibe 44 fixed to the base plate 4, and the lower end surfaces of the magnetic plates 431, 432 It is designed to be constantly attracted to a carriage guide bar 45 made of a magnetic material and placed horizontally on the floor x.

On the other hand, on the rear side of the sheath frame 39, a microswitch e having three switch parts El and e3 is fixedly installed inside, and a lever e'' of the switch e is installed on the rear wall of the sheath frame 39. The hole 4 of the magnetic plate 432 on the rear side passes through the window hole 39''.
It is attached to 3″.

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 is adsorbed to the carriage guide bar 45, so that the When the carriage Y is moved to the left, it is slid to the right sliding limit position against the sheath frame 39 and then moved together with it, and when the carriage Y is moved to the right, contrary to the above, it is moved to 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. , that is, from the switch part e1 for detecting the carriage running direction,
1Hj by reversing the travel of the carriage Y as shown in Figure ■.
A binary electrical signal that is inverted from RL to RL or vice versa can be obtained. Next, regarding the left and right knitting needle selection mechanisms Fl and Fr that finally carry out the front and rear needle selection of the knitting needles N, the third
Referring to Figures 8 and 10, both have substantially the same structure, although the arrangement of component parts is symmetrical.

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

On the other hand, a 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 10, the outer half 49 is on the outside when viewed from the carriage Y.

is a tapered surface that descends inward, and the inner half 493
is a horizontal plane that is slightly lower than the normal height of pad N''. Therefore, in the process of passing through this pad passage 491, pad N'' is on the outside 49.

From the middle, the plate is gradually pushed down against the spring 51 (FIG. 3), comes into pressure contact with it at the inner half 493, and passes through the pad passage 491 in a tight fit state. 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 of it is paved passageway 491
The lower surface of the horizontal portion facing the inner end of the pad passage 491 is a continuous surface that is flush with the inner half 493 of the upper wall surface of the pad passage 491.

In addition, the other magnetic conductor 48 has a notch 4 halfway from the upper side in a vertical portion below the carriage base plate 4.
81, and the magnetism from the electromagnet 46 acts on the outer vertical portion 482 on the outside with respect to the notch 481, but hardly acts on the inner vertical portion 483 on the inside.

The magnetic conductor 48 is attached to the pad passage 491 with its outer vertical portion 482 along the rear wall surface of the pad passage 491.
Its outer vertical portion 48 faces inward.

The vertical front surface from the inner vertical portion 483 is a surface that slopes rearward inward from the inner end (putt outlet) of the putt passage 491, as shown in FIG. Further, 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. The pad N'', which is curved and passes through the pad passage 491, has an outer vertical portion 4 within this width T.
The rear surface is brought into pressure contact with the vertical front surface of the magnetic conductor 82, and the head end is brought into pressure contact with the horizontal lower surface of the other magnetic conductor 47, and the front surface of the inner vertical part 483 of the magnetic conductor 48 and the horizontal surface of the magnetic conductor 47 are pressed. There is a pad N″ between the rear edge of the part.
A gap passageway 51 (FIG. 8) is formed that is inclined rearward to the extent that the spacer can enter therein.

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

After entering the pad passage 491, the pad N'' is gradually pushed down with its back and forth movement restrained as the carriage Y travels, and its head end is brought into pressure contact with the horizontal lower surface of one of the magnetic conductors 47, and the pad N'' is pushed down as the carriage Y runs. 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
and the outer vertical portion 48 of the magnetic conductor 18. By exciting different magnetic poles in each, a kind of magnetic path is formed between them via the pad N'', and the outer perpendicular portion 48 of the magnetic conductor 48.

Because the pad N'' is tilted rearward, the pad N'' is slightly attracted and biased rearward along its outer vertical portion 482, and the magnetic conductor 4
It enters the gap passage 51 from the horizontal lower surface of the magnetic conductor 47, and immediately rises to a normal height behind the horizontal portion of the magnetic conductor 47. The pad N″ that entered the gap passage 51 is connected to the rising portion of the magnetic conductor 47 on the carriage base plate 4.
By disposing the magnet piece 52 between the rising part extending from the inner vertical part 483 (the part not subjected to the magnetic action of the electromagnet 46) of the magnetic conductor 48, the magnet piece 52 is subsequently attracted and biased backward. , it goes further and passes through a rear guide path formed by a group of cams arranged on the back side of the carriage Y. On the other hand, when the electromagnet 46 is in a de-energized state, the pad N
'' is not attracted by the outer vertical part 482 of the magnetic conductor 48, so it continues straight even after passing through the pad passage 491 while being pushed down by the horizontal part of the magnetic conductor 47, and continues to move steadily beyond the inner edge of the horizontal part. After rising to a height, the vehicle passes through a forward guide path different from that in the case of excitation described above.

The left and right knitting needle sorting mechanisms F' and Fr are made effective by switching the electromagnet switching switch E2 in the micros and inch e of the carriage reversing switch mechanism E according to the traveling direction of the carriage Y. Only one electromagnet 46 to be operated (in this example, the one on the front side in the direction of movement of the carriage Y) is supplied with power for the needle selection operation.

The left and right knitting needle sorting mechanisms Fe, Fr have the above-mentioned configuration, and the knitting needles N with pads N'' fitted into the pad passages 491 are arranged in the sorting mechanism F' or Fr on the front side in the direction of movement of the carriage Y. However, even among the inserted knitting needles N, there are some that are located outside the range of the left and right needle selection range setting switch activation pieces 3e and 3r. In this case, the electromagnet 46
does not receive any excitation command and remains in a non-excited state, so that it is not subjected to the above-mentioned sorting action by the electromagnet 46. Next, regarding this configuration, refer to FIGS. 8 and 9. explain.

The left and right switch activation pieces 3', 3r both have a cam groove 31 running left and right on their upper surfaces, and a plurality of protrusions 32 protruding from the front end of their lower surfaces that are fitted from above in a needle groove manner. A plurality of pad engagement grooves 33 are formed on the side surface to tightly receive the pads N'' of the knitting needles N, both of which have projections 3.

The same goes for the fact that by fitting the pad N'' into the rear end of the needle groove type 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. However, the shapes of the cam grooves 31 are symmetrical to each other.In other words, the left switch actuating piece 3e is formed by the arrangement of the front and rear cam parts 34 and 35 that form the front and rear side walls of the cam groove 31. However, the front side is on the right and the rear side is on the left, but the right switch activation piece 3r
The relationship is the opposite of 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 G', Gr are operated by engaging the switch actuating pieces 3e, 3r as the carriage Y travels. It is equipped with. Left and right switch mechanism G
', 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
It is connected to the lever of a 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, causing the crank 53 to rotate. The microswitch 56 is switched by the microswitch 56. That is, the microswitches 56, 56 of the left and right switch mechanisms Ge, Gr
are both turned on when the corresponding protrusions 55, 55 are both within the interval between the left and right switch activation pieces 3e, 3r, and are turned off when they move outside this interval. The left and right protrusions 55, 55 are located at the sorting points of the left and right knitting needle sorting mechanisms Fe, Fr, that is, on the rear extension line of the t-width portion, and the left and right switch mechanisms Ge, Gr is switched when the selection points of the left and right knitting needle selection mechanisms Fe and Fr approach the installation positions of the switch activation pieces 3' and 3r on the needle bed X, respectively, as shown in Fig. 18 ■ and ■. As shown, an electrical signal is output from RHJ to RL or vice versa, and the electrical signals from both switch mechanisms G' and Gr are sent to the microswitch e of the carriage reversing switch mechanism E. By means of the effective needle selection range indicating switch section E3, only the part 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 operated from the time when the needle selection end detection switch mechanism G' or Gr on the side that performs effective needle selection operation is turned on until it is turned off. In other words, while the needle selection point of the knitting needle selection mechanism 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 1HJ indicating the effective needle selection range is output. However, when the interval is outside the above range, the signal RL. During the above-mentioned 1H output, the above-mentioned memory storing digital electric signals related to the knitting pattern is read out, and only during that 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 3e and 3r, but since the traveling speed of the carriage Y is not constant and varies greatly, This must be done in accordance with the timing of the carriage Y's travel.

Therefore, photoelectric sensors He, Hr are attached to the carriage Y at the rear end of the base plate 4 at positions corresponding to the left and right knitting needle sorting mechanisms F', Fr, respectively. Hr has slits X3, which are arranged in a row in a one-to-one relationship with needle groove type, on the rising wall X1 at the rear end of the needle bed X. , as a kind of linear encoder, the first signal is detected by the photoelectric sensors H' and Hr.
8 As shown in Fig. 1, a pulse that matches the traveling timing of the carriage Y, that is, a timing pulse, is output, and this timing pulse controls the reading of the memory mentioned above. The photoelectric sensors H' 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, Hr are taken out as valid only by the carriage reversing switch mechanism E that corresponds to the knitting needle selection mechanism Fe or Fr on the side that performs the effective needle selection operation. It's starting to become easier.

The mechanical configuration of the hand knitting machine is as described above, and next, the 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.

An electric signal related to card scanning by the scanning sensor c is transmitted to the scanning member b by an effective scanning data forming circuit C.
Only those related to the rightward stroke from the original position, which is the left stroke end, to the reverse position, which is the right stroke end, are taken out as valid, and the card feeding and scanning instruction circuit CS, needle selection unit number setting circuit NS, and memory control circuit The signal is input to the MCl function discrimination circuit FS.

The card feeding and scanning instruction circuit CS is configured to receive an electric signal when the left limit switch 33', which is the scanning member original position detection means, is turned on.
The instruction circuit CS determines 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, only when the scanning member b is in the original position. It determines whether the card is marked or not, and supplies an electrical signal according to the determination result to the card feeding and scanning control circuit SC, which causes the control circuit SC to set the card feeding drive circuit CD to the above mark or no mark. In a controlled manner, said electromagnet 16 or 16'' for card feeding is driven, whereby the card 1
The search mark 36, feed control mark 34, etc. displayed thereon are automatically transferred by the interval.

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 the range 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 SC is configured to receive an electric signal when the right limit switch 33r, which is a scanning member reversal position detection means, is turned on, thereby causing the control circuit SC to operate as a scanning member drive circuit. SD is controlled so that the drive circuit SD also supplies sufficient current to the coil 31 of the scanning member b to allow the scanning member b to travel back and forth at once.

On the other hand, among the sampling pulses related to the linear encoder reading of the sampling sensor d, only those related to the right row scan are taken out as valid by the effective sampling pulse forming circuit D, and inputted to the pulse separation circuit PS. 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 the pulse for sampling the knitting pattern is separated from each other. The pulses (total of 120f) are thinned out and removed by 2 pulses for each reporter grid when using card 1 in which the number of rows of the reporter grid in the knitting pattern entry field 1p is R36 as described above. , the remaining pulses are sent to the write address designation circuit WA and the memory control circuit MC, and one pulse for sampling the search mark 36 is sent to the needle selection unit number setting circuit NS, and the pulses are sent to the above-mentioned function. Four pulses for mark sampling are respectively input to the function discrimination circuit FS. The needle selection unit number setting circuit NS is as follows:
By the inputted one pulse, the electric signal related to the reading of the search mark 36 from the effective scanning data forming circuit C is sampled, thereby setting the sampling state of the mark in the needle selection unit number setting field 1s, In other words, an instruction to electrically preset the number of needle selection units is given, and the setting circuit NS receives the pulse before thinning for sampling the knitting pattern from the pulse separation circuit PS. , the needle selection programmed in the needle selection unit number setting field 1s depends on at which pulse the electric signal related to reading the mark in the needle selection unit number setting field 1s is input from the effective scanning data forming circuit C. The number of units is stored using a digital electrical signal, that is, the number of needle selection units is electrically preset. Then, the needle selection unit number setting circuit NS determines whether or not to thin out the pulses for sampling the knitting pattern and how many pulses to thin out in accordance with the stored number of needle selection units. For example, when the number of needle selection units is between R6 and R36, the pulse separation circuit PS is controlled to thin out two needles as described above. When the circuit NS receives an instruction to electrically preset the number of needle selection units as described above, it controls the card feeding and scanning instruction circuit CS and the card feeding and scanning control circuit SC, so that the scanning member b can select needles. After scanning the unit number setting field 1s once and returning to the original position, the card 1 is automatically moved until the scanning member b reads the lowest mark among the feed control marks 34. It has come to function as a transporter.

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

The memory control circuit MC samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C using the pulse from the pulse separation circuit PS as described above, and samples the electrical signal related to the scanning of the knitting pattern from the effective scanning data forming circuit C, and divides it into one knitting needle and each bit. converts the digital electrical signal into a corresponding digital electrical signal (see FIG. 13 In addition, an electric signal corresponding to the carriage traveling direction from the carriage traveling direction detection switch section E is used to separate the cases of scanning by the leftward movement of the carriage Y and the case of scanning by the rightward movement, respectively. The information is stored separately in the storage unit, that is, in two storage units.

The function discrimination circuit FS uses the four pulses inputted from the pulse separation circuit PS as described above to
The electric signal related to function mark scanning from the effective scanning data forming circuit C is entered in the function mark entry field 1f.
Samples are taken for each reporter grid row, and the sampling of the two columns on the left side of that reporter grid row is input to the card feeding and scanning control circuit μSC, which controls whether or not card 1 is sent in the forward direction. The data related to the sampling in the two columns on the right side are input to the 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 SC, and memory control circuit MC operate using manual operation means, that is, a clear button CB provided on the operation panel 2 (FIG. 1) of the control box B. It can be controlled manually by operating the button, and by operating the button, the card 1 can be transferred by one step in the direction opposite to the transfer direction before the button operation, and the data currently stored in the memory MEM can be cleared. It has become possible to do this, so it can be used to re-knit 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 designed so that it can be stopped. - Furthermore, when performing a special organization, 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 card feeding and scanning are performed in special operations. It is becoming more and more common to be forced to do things.

Next, for the specific configurations of the effective scanning data forming circuit C, effective sampling pulse forming circuit D, pulse separating circuit PS, needle selection unit number setting circuit NS, and function discrimination circuit FS, see FIGS. 12 and 13. Explain. The R-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 in the original position. The AND gates 61c and 61d are opened only during the forward movement of traveling from the to the reversing position, and only during this time the output signal of the scanning sensor c and the output signal of the sampling sensor d are transmitted to the effective scanning data forming circuit. C, the signal is outputted from AND gates 61c and 61d as the output signal of the effective sampling pulse forming circuit D (see FIG. 13, ■, ■, and I).

As shown in FIG. 13, the output of the limit switch 33' is 1Lj when the scanning member b is at the original position, and becomes RHj when the scanning member b moves away from the original position. An R-S flip-flop 62 for separating sampling pulses is set when the scanning member b moves away from the original position, and the R-S flip-flop 62 separates the first pulse from the effective sampling pulse forming circuit D (the search mark 36 It is reset by the falling edge of the sampling pulse).

The O output of this flip-flop 62 opens the AND gate 63 which receives the pulse from the effective sampling pulse forming circuit D, and as a result, the AND gate 63 receives the pulse from the effective sampling pulse forming circuit D. Pulses excluding the pulses for sampling the search mark 36, that is. Pulses for sampling knitting patterns and pulses for sampling function marks are output.

On the other hand, the Q output of flip-flop 62 is added to AND64, which is in turn connected to flip-flop . When the Q output of the mouth knob 62, the output of the effective scanning data forming circuit C, and the output of the effective sampling pulse forming circuit D are all RHJ, that is, the scanning sensor c is connected to the search mark 36 on the card 1 and the number of needle selection units. Scanning across the setting field 1s (scanning along the P1-P1 line in Figure 13, ■ in the figure is the output waveform of the effective scanning data forming circuit C at that time)
When the sampling sensor d is connected to the search mark sampling slit 38 of the linear encoder 37
When s is detected, one pulse is output as shown in (■).

Therefore, this pulse output from AND64 is
This indicates that the search mark 36 has been detected. The R-S flip-flop 65 is used to store the fact that the search mark 36 has been detected by the output of the AND 64 (actually, the output is inverted by the knot 6).
is now set.

This flip-flop 65 is reset by the output of AND66. AND66 has flip-flop 6
5, the O 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.
6, these outputs are shown in Figure 13 as ■,■,■,■
As is clear from the above, when all the needles are RH, that is, after the search mark 36 is detected as described above, when the mark placed in the needle selection unit number setting field 1s is detected, As shown in (2), one pulse is output, and the flip-flop 65 is reset by this pulse.

Therefore, the flip-flop 65 stores the detection of the search mark 36 only until the mark in the needle selection unit number setting column 1s is detected, as shown in (3).

Note that the above-mentioned single pulse also controls the above-mentioned card feeding and scanning instruction circuit CS and control circuit SC as described later. On the other hand, as mentioned above, the pulse (■) from the AND gate 63 from which the pulse for sampling the search mark 36 has been removed is hexadecimal -2
It is counted by a hexadecimal 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 six pulses ■. Each time, the count value of the counter 67 increases by one.

The count value of this counter 67 is the output of the AND 66 above
When the mark in the needle selection unit number setting column 1s is detected by the gate network 68 which uses .

This memory 69 is reset at the rising edge of the output (2) of the flip-flop 65, that is, at the time of sampling the search mark 36. Further, the count output of the counter 67 is input to a gate network 70 which discriminates whether the number of pulses (2) from the ANDKATE 63 is less than 120 or more than 121.

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 is output from one output terminal as shown by arises and opens AND gate 711, again? If it is 21 or more, an output is generated from the output terminal of R2J and the AND gate 712 is opened.

Therefore, the AND gate 711 outputs 120 pulses for sampling the knitting pattern as shown in M, and the AND gate 712 outputs 4 pulses for sampling the function mark as shown in ■.
pulses will be output.

One pulse from the AND gate 711 is input to a pulse selection circuit 72, where it is divided into three types of pulses.

That is, the pulse selection circuit 72 has its 11th output system as shown in (■) above. The output system of R2j includes a T-type flip-flop and an AND gate connected to this output side, as shown in x■. The even-numbered pulses are thinned out and the remaining pulses are output, and the 13J output system includes a ternary counter and an AND gate connected to this output side.
As shown in , 3n-1 out of 12 pulses
is an integer), the pulses are left and the others are thinned out. On the other hand, the output of the memory 69 which stores the number of needle selection units programmed in the needle selection unit number setting field 1s in the card 1 as described above is the same as the above three types output from the pulse selection circuit 72. It is input to the gate network 73 for selecting which of the pulses is actually used as a sampling pulse, and if the number of needle selection units is between 6 and 36, the output is output from the R3 output system of the gate network 73. occurs, and the AND gate 743 opens, and x of the above three types of pulses
The pulse of (■) passes through the OR 75, and if it is between 42 and 60, an output is generated from the output system of R2l, the AND gate 742 opens, and the pulse of X (X) passes through the OR 75.
Further, if it is between 66 and 120, an output is generated from the RL output system, and the AND gate 741 is opened so that the pulse of x■ passes through the OR 75.

In this way, the sampling pulses for sampling knitting patterns are divided into three types, and the pulses are selectively extracted depending on the number of needle selection units. As shown, the number of grid rows in the knitting pattern entry field 1p is 36, and the number of needle selection units is 6, 12, 18, 24, 3.
In addition to the cards that can be selected as 0, 36, as shown in Figure 19, the number of grid rows is 60 and the number of needle selection units is 42, 42,
48, 54, and 60, and as shown in FIG.
,72,78,84,90,96,102,108,1
This is because a total of three cards, which can be selected from 14 and 120, 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 the total number of pulses shown in FIG. The data is input to the memory control circuit MC and the write address designating circuit WA, thereby causing the output of the effective scanning data forming circuit C (the scanning sensor c moves the card 1 along the P2-P2 line in FIG. (The output when scanning the knitting pattern is shown in ■. After the conversion, the data is sequentially stored at a certain address in the memory MEM by the address designation operation of the write address designation circuit WA shown by X2.

The digital electrical signals are stored in the memory MEM as described above for all the signals from the left edge to the right edge of the one-level register grid in the knitting pattern entry field 1p, 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 1s. The output is converted into a binary number by a code converter 76 and 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 712 are as follows:
They are separated from each other by a pulse discrimination circuit 77 composed of a group of gates.

That is, the above-mentioned four pulses are counted by the counter 78, and the decoder 79 generates an output from the output system of 1L-R4J according to the number of the above-mentioned pulses as shown by The gates in the discriminator circuit 77 are opened, and the R of the pulse discriminator circuit 77 is thereby opened.
The output systems 1J to R4 sequentially generate outputs in accordance with the above pulse order as shown by XX and XXI. The four pulses separated by the pulse discrimination circuit 77 are input to a function memory circuit 80 comprised of a D-type flip-flop amplifier, etc., where the output (2) from the effective scanning data forming circuit C is sampled. , is performed for each reporter grid row in the function mark entry field 1f, and the sampled data is
As shown in XII, each grid column is stored separately.

Then, r1-R of this function storage circuit 80
Outputs of 01 and 52 of the 4 output systems are as follows:
I will explain it in detail later. The output of R2 is input to the aforementioned card feeding and scanning control circuit SC to control the forward feeding of the output card 1 of JlJ, and the output of R2 is designed to control the backward feeding. The output of R4 is inputted to the aforementioned function drive circuit FD, which controls each required function operation other than card feeding. Next, the specific configuration of the card feeding and scanning instruction circuit CS and the control circuit SC will be explained with reference to FIGS. 14 to 16. The above-mentioned clear button CB is used not only in case of incorrect organization as mentioned above, but also as a kind of start button to start the organization by card 1. First, before explaining the behavior caused by that operation,
An outline of how to use the hand knitting machine will be explained below.

First, operate the carriage in the usual manner to perform the required knitting such as waste knitting, and when the knitting is completed to the point where the pattern is to be added, the carriage Y is set 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 of the ends. In this state, the card 1 is fed manually, that is, by turning the ratchet wheel 14 by hand, and the scanning sensor of the scanning member b is moved so that the upper and lower middle portions of the search marks 36 are at their original positions. Set it opposite to c.

Afterwards, when you press the clear button CB, . When the card 1 is in the forward or reverse direction, the direction is not determined as will be described later), and then the scanning member b is moved by one pitch, for example, along the line P1-P1 shown in FIG. After the number of needle selection units is set as described above during the outgoing process, the forward movement of the card 1 is started again at the end of the backward movement. This continues intermittently until the lower feed control mark 34 is detected by the scanning sensor c, upon which it stops and the scanning member b is immediately moved along the line P2-P2 in FIG. After traveling back and forth and returning to the original position, the series of operations by operating the clear button CB is completed.After this, work necessary for pattern knitting, such as inserting the desired colored thread into the thread opening of the carriage Y, is completed. Then, if the carriage Y is repeatedly moved back and forth until it passes the left and right switch activation pieces 3' and 3r installed on the needle bed You can compose the pattern as you like.Now, when you operate the clear button CB,
The accompanying signal (FIG. 15 1) is inverted at knot 81, passes through OR 82, is inverted again at knot 8'', and is output as a card feeding and scanning instruction signal from the card feeding and scanning instruction circuit CS. 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 SC are set.

By setting the flip-flop 83, the Q output ■ is
It is applied to a card feed drive control circuit 86 consisting of a gate network through an AND 85, and outputs one of the output terminals r1 on the forward sending side of this control circuit 86 or R2J on the backward sending side, for example, R2l. One pulse shown in ■ is generated from the output terminal of the card drive circuit CD, and one of the pair of electromagnets 16 and 16'' for card feeding is operated. , the card 1 is adapted to be transported 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 n output (2) of the flip-flop 88.

Further, the output of the effective scanning data forming circuit C is input 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 (2) of the flip-flop 83. The D-type flip-flop 88 is designed to sample and output the input to the D terminal using the rising edge of the input pulse to the T terminal, and the timer 87 is activated by operating the clear button CB as described above. When the card 1 is sent by one pitch, the retrieval mark 36 still does not cross the scanning line of the scanning sensor c either above or below, so a valid signal is sent to the D terminal of the flip-flop 88. An RH output indicating that a mark has been detected is inputted from the scanning data forming circuit C, and the flip-flop 83 is reset by the output of the flip-flop 88.

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 clear button CB is operated, the R-S flip-flop 89 is set, and its output causes the feed direction reversal circuit 9 to be set for the set time, that is, until it is reset by the right limit switch 33r.
0 is controlled to switch the output operation of the card feed drive control circuit 86 and transport the card 1 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 output from the above-mentioned scanning member ゜drive. times μS
D is driven to move card 1 forward only when it is stopped. This forward movement ends when the flip-flop 84 is reset by the left limit switch 33r, as shown in FIG. As a result, scanning member b immediately begins to move back.

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 33' at a considerable speed, and the reaction causes the limit switch 33 to be turned on. ' may chattering as shown in FIG.
The home position return signal from 3e is delayed as shown in FIG.
4, so that a force is applied to the scanning member b to move it further to the left even after reaching the left stroke end, thereby eliminating the above-mentioned fear. It has been prevented.

As described above, by operating the rear button CB, the scanning member b is
When the needle moves back and forth, the needle selection unit number setting field 1s is set by the needle selection unit number setting circuit NS during the forward movement as described above.
The electrical setting of the number of needle selection units programmed in the needle selection unit is performed, and when the setting is performed, one pulse (no. The R-S flip-flop 96 in the card feeding and scanning instruction circuit CS is set by (■ in Figure 15), and its Q output (■ in the same figure) is the OR 82, NOT 8.
2'' to set the card feeding flip-flop 83 again [■].However, the card feeding drive control circuit 86 can now receive a signal from the left limit switch 33e via the knot 97. Since the card feed drive circuit CD is driven only when the scanning member b is in the original position, the card 1 is configured to drive the card feeding drive circuit CD only when the scanning member b is in the original position.
It will not be transferred while the vehicle is running. When the scanning member b returns to its original position, since the flip-flop 83 has already been set as described above, the pulse of the timer 87 is input to the card feed drive unit u 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 reset, has been reset by the right limit switch 33r, the Q
The output is directly applied to the card feed drive control circuit 86 through the feed direction reversing circuit 90, and a pulse is outputted from the output terminal of RlJ as shown in {circle around (2)}, so it is in the forward direction.

The feed direction reversing circuit 90 is composed of two υt alistic OR circuits, and when the output of the flip-flop 89 is RLJ, the input from the flip-flop 91 is directly inputted to the control circuit 86, and conversely, the above-mentioned When the output is RH, the above input is inverted, and the flip-flop 91 is configured such that its Q output is RH when set.
By becoming J, instruct card 1 to be forwarded,
Further, at the time of reset, the O output becomes RH to instruct reverse direction feeding. Card 1 is first transferred by one pitch, but at that time scanning is performed. Since the sensor c is still detecting the search mark 36, the card feeding flip-flop 83 is about to be reset by the output (2) of the D-type flip-flop 88.

However, since this flip-flop 83 is given priority to the set signal, and the flip-flop 96 supplying the set signal is activated by the output X of the AND 99 (passing the Since it is not reset (reset by a falling edge) by the output of the effective scanning data forming circuit C (output of the effective scanning data forming circuit C), the set state is still maintained.
is then repeatedly transported intermittently in the forward direction. When the search mark 36 is moved away from the position facing the scanning sensor c due to such forward movement, the flip-flop 96 is reset at that moment, and the set signal to the card feeding flip-flop 83 disappears. The input to the D terminal of the D-type flip-flop 88 to be reset (the output of the effective scanning data forming circuit C) also corresponds to the no mark, so the output of the D-type flip-flop 88 is the same as that of the flip-flop 83 as shown in (■). Since the flip-flop 83 still maintains the set state even though the card 1 is not reset, the flip-flop 83 still remains set.
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. As a result, the 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 above-mentioned clear button CB, is reset via AND92 by resetting the flip-flop 83. By inputting the input to the scanning member drive circuit SD, the scanning member b reciprocates to scan the scanning sensor c force field 1 along the line P2-P2 in FIG. Member b stops, thereby also completing the above-described series of operations performed by operating the clear button CB. Note that the digital electrical signal (X■ in FIG. 13) representing the knitting pattern obtained by the first one-stage scanning is written to both of the two storage sections of the memory MEM at the same time. However, its configuration is not shown. The first scanning of the knitting pattern entry field 1p and the function mark entry field 1f of card 1 is automatically performed by operating the clear button CB as described above, but subsequent scanning is performed automatically by operating the clear button CB. This is automatically performed for each stage by reciprocating the carriage Y, which will be explained next.

When the carriage Y reverses its travel, the carriage travel direction detection switch part e in the carriage reversal switch mechanism E
The output of 1 (Fig. 16 1) is inverted from RH to RL or vice versa, but this inversion is not, 2
1 differentiator circuit and . The signal shown in FIG.
It is set to 1, and it is stored that the carriage Y has been reversed.

When the carriage Y enters the effective needle selection range defined by the left and right switch activation pieces 3' and 3r by traveling after this reversal, the effective needle selection range indicating switch section E3 is activated as described above.
Since the output of 5HJ becomes 5HJ as shown in FIG. Knot 82″ through ora 82
After being inverted as shown in ■, the card feeding and scanning instruction signal is outputted from the card feeding and scanning instruction circuit CS, and the flip-flops 83 and 84 in the control circuit SC are inverted as shown in ■ and X■. It is now set.

By the way, since the output of knot 82'' is also used as a reset signal for the flip-flop 101, the flip-flop 101 is reset the moment the output of knot 82'' occurs, and as a result, AND102, knot The output of 82'' becomes a trigger waveform as shown in V and ■.

By setting the flip-flop 83, as in the case of operating the clear button CB described above, the pulse ■ from the timer 87 is activated by the card feed drive control circuit 86 as shown in ■.
Card feed drive circuit C through output terminal 11 of
D is input, and the first pulse (2) is first sent in the forward direction by one pitch, but this one pitch movement causes the feed control mark 34 to miss the scanning sensor c, so that the effective scanning data The output (■) of the 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 87 outputs the next pulse and the card 1 is further transferred by one pitch. Ru.

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 X of flip-flop 84 for instructing scanning member forward movement
Since (1) is input to the scanning member drive circuit SD via the AND 92 as shown by x (2), the scanning member b moves forward immediately after the transfer of the card 1 is stopped, and the left limit switch 33r is turned on. By the way, the output XV
The flip-flop 84 is reset by this, and the flip-flop 94 for instructing the scanning member to move backward is set, so that the scanning member b moves back and stops when it reaches the original position to perform one-stage scanning of the card 1. Finish.

Thus, the carriage Y is connected to the left and right switch activation pieces 3e, 3.
Every time card 1 is moved leftward or rightward from outside the range of r to within the range, card 1 moves to the feed control mark 34...
They are automatically transported by an interval length of , and each stage is scanned by the scanning sensor c.

Note that the output of r1 of the function storage circuit 80 in the function discrimination circuit FS (a mark was applied to the leftmost mark grid row of 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 (a mark is placed on the second recorder grid column from the left edge of the above). The output (output when the card was set) is reset, and card 1 can be sent forward or backward by marking any of the two grid lines mentioned above. 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 is such that a continuous pattern can be repeatedly knitted. Furthermore, the AND 102 generates the output shown in FIG. It is designed to operate in the same way regardless of which direction it enters, but when button W is operated, the carriage Y is reversed from the left row to the right row and the effective needle selection range is selected from the right. An output is generated from another AND 103 only when the input signal is entered, and card feeding and scanning are performed only at that time.

Furthermore, the clear button CB functions as a kind of start button when starting the scanning of card 1 as described above, but if it is operated during the scanning stage of the knitting pattern, each time the clear button CB is operated, the card 1 can be transferred by one step in the opposite direction,
It is clear from the above.

The above-mentioned input function section transfers and runs the card 1, and the knitting pattern drawn in the knitting pattern entry field 1p is read one by one one by one with the knitting needles N.
Memory MEM as a digital electrical signal corresponding to
Next, by reading out the digital electrical signals stored in this memory MEM in accordance with the travel timing of the carriage Y while it is traveling within the effective needle selection range, The left and right knitting needle selection mechanism Fl
, Fr to select the knitting needles N will be explained with reference to FIGS. 17 and 18.

When the carriage Y enters the effective needle selection range, the effective needle selection range indicating switch section E3 of the carriage reversal switch mechanism E outputs the signal RH as shown in FIG.
When the output signal is output, the read address designating circuit RA is in the set state only during the output. This read address designation circuit RA includes an up/down counter, and is configured to count the timing pulses I inputted from the timing pulse generators H' and Hr every time the carriage Y travels by one pitch of the knitting needle. However, the counted value can be calculated from the card by inputting a parallel binary signal (more 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. The number of needle selection units (in this example, 12) is programmed in the needle selection unit number setting field 1s of No. 1 and is preset in the same way as the number of needle selection units (12 in this example). This is done using a signal (2) representing the carriage running direction from e1, and the timing pulse is added or subtracted depending on the carriage running direction.

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

In other words, it can be said that this circuit RA encodes the knitting needles N between the left and right switch activation pieces 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 (2) representing the carriage traveling direction is supplied to the memory control circuit MC. The digital electrical signal stored in the memory MEM is input to the MC as a signal to determine which of the two storage sections of the memory MEM is to be read. In this example, 12 bits from 0 to 11 are repeatedly read out from the corresponding storage section, and as shown in It is becoming more and more common.

The waveform processing circuit WP receives the signal ■ from the effective needle selection range indicating switch E3, and supplies the signal from the memory control circuit MC as valid to the electromagnet drive circuit MD only during RHO. The output of this drive circuit is inputted to the electromagnet 46 of the knitting needle sorting mechanism Ff or Fr, which is the one that performs the effective sorting operation, by means of the electromagnet changeover switch section E2. ing.

Thus, the knitting needles N between the left and right switch activation pieces 3e and 3r
As shown in ■, one pot is considered to be one group, and sorted according to the form of the knitting pattern drawn between the knitting pattern entry field 1p's leftmost knitting grid and the 12 knitting pattern grids to the right. (For example, in FIG. 18, the oval indicated by a solid line indicates the forward deflection, the filled-in oval indicates the backward deflection, and the oval indicated by the broken line indicates the one in the rest position where it is not subjected to the needle selection action.)

By the way, as mentioned above, the knitting pattern entry column 1p is scanned over the entire length of its left and right ends, and all 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 setting column 1s.
For example, if it is Rl2J, even if the knitting pattern is stored further to the right of the 12th reporter grid from the left on the knitting pattern entry field 1p, the recorded part on the right side will not be scanned. Although it is temporarily stored in the memory MEM, it is not read out as a signal for needle selection.

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

The pattern left/right selection means RL is configured such that the output electric signal is inverted from 1H to 1L as shown in FIG. This signal is compared (exclusively ORed) with the signal (2) representing the carriage running direction in the comparison circuit CO, and the comparison signal (2) causes the read address designation circuit RA to The direction of addition/subtraction of the up/down counter is specified.

Accordingly, the count value of the read address designating circuit RA determines whether the above-mentioned relationship (■) or X (X) is adopted for the movement of the carriage Y in a certain direction based on the operation of the pattern left/right selection means RL. Even if the knitting patterns on card 1 are the same, in the case of ■ and x■, the knitted patterns 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 1LJ to 1HJ or vice versa as shown in (3) by switching the manual operation section, and supplies it to the waveform processing circuit WP. By operating this means MS, the waveform processing circuit WP determines whether to pass through the ζ input X from the memory control 4C without inverting it or invert it as shown in (2). It is something.

Therefore, by operating this means MS, the front and rear sorting mode of the knitting needles N can be reversed, thereby reversing the ground pattern of the pattern to be knitted without changing the knitting pattern on the card 1. There are things you can do.

Further, when the clear button CB is operated, the memory control MC 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.

That is, in the above embodiment, the single coil 31 of the scanning member b is fitted into the guide rod 28, and by passing currents of opposite polarities through it, the coil 31 is connected to the left and right sides using the permanent magnet 32 as a stator. Magnetic forces in opposite directions are applied to each other, thereby causing the scanning member b to reciprocate. However, two coils with opposite winding directions are used, and the guide rod 28 is made of a magnetic material. Even if current is passed through the two coils alternately and a magnetic force is generated between the coils and the guide rod 28, the scanning member b can be moved back and forth. 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. It is also possible to use a card on which knitting patterns, function marks, and needle selection unit number setting marks are printed in advance.

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

Furthermore, in the above, the effective scanning of scanning member b is
Although I have followed you during the outbound journey, it is also possible to follow me during the return journey.

In order to perform effective scanning in either the forward or backward direction, as described above, the electric signals from the scanning sensor c and the sampling sensor d are taken out during both the forward and backward strokes, and then the electric signals for the forward or backward scan are extracted. In addition to the method of extracting only those related to one of the runs,
Scanning sensor c and sampling sensor d
Even if this is performed by operating (turning on/lighting the light emitting element) only for either the forward or the backward travel, the result is substantially the same. As is clear from the above description, the organization information scanning device of the present invention is capable of driving a traveling body (a scanning member that is driven to automatically reciprocate from the original position to the turn-back position and then from the turn-back position to the original position at once). The present invention is characterized by comprising a drive mechanism and a control circuit that controls the transfer drive mechanism to automatically transfer the information recording medium only when the traveling body is located at the original position.

Therefore, according to the present invention, when the carriage shifts from side to side as in the past, the same reading is not performed twice and the composition information recording medium is not transferred inadvertently. Reading can be performed efficiently and without scanning errors.
