Description

DETAILED DESCRIPTION OF THE INVENTION The present invention enables a knitting machine to perform various functional operations such as thread exchange, feeding condition of the recording medium itself, and start or end of needle selection operation on the same predetermined knitting information recording medium. By recording multiple pieces of function information in the respective record fields, the multiple pieces of function information can be automatically separated and read using the same weak member, thereby allowing multiple function operations to be recorded in the same record. It is economical because it can be programmed on the medium, and each function operation can be performed automatically according to the program, and all function information can be read with one scanning member. The present invention relates to a completely new function information reading method that achieves the above effects, and a function information reading device that can implement the method more effectively.

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

First, regarding the overall outline of the hand knitting machine to which the present invention is applied,
Referring to FIG. 1 showing the plane, the knitting machine main body X having the needle bed X can be loaded with a knitting information recording medium, that is, a knitting program card 1 on which knitting patterns and function marks are drawn, and the knitting information can be recorded on it. A reading device A according to an embodiment of the present invention is equipped with a scanning member 2 for optically scanning knitting patterns and fan cushion marks, and is used to manually operate various mechanisms described below in addition to the reading device A. Manual operation means are provided on the operation panel 3, and the control box B and the single stitch bed X are movable in the length direction and can be set at a desired position in the length direction. By keeping the left and right cursors 41s4r, you can divide the range of needle selection.
It is installed at the rear of the carriage Y, and
In response to electrical signals obtained by scanning the knitting pattern, the knitting needles (not shown in Figure 1) arranged in rows on the needle bed X are effectively sorted backwards or forwards using electromagnetic force. A pair of operating left and right knitting needle selection mechanisms CI and Cr are arranged at a predetermined distance apart from each other.

The scanning member 2 can move left and right following the movement of the carriage Y, but can only move within a predetermined left and right limited range, which corresponds to the above-mentioned left and right limited range of the carriage Y. While the card 1 is running, the card 1 is scanned horizontally and linearly to record the configuration pattern and function marks, and the corresponding electrical signals are output, and the subsequent processing of the electrical signals is done electronically. Furthermore, power is supplied to the electrical components of the pair of knitting needle sorting mechanisms CI and Cr through a power collector assembly D that is long on the left and right and is installed on the back of the carriage Y. While the effective sorting action is performed from the side of the main body (Except for items in the rest position, which do not receive any sorting at all).

First, the specific configuration of the reading device A, which is an embodiment of the present invention, will be explained with reference to FIGS. 2 to 11.

A card feed roller 5, which is a recording medium loading member for supporting the knitting program card 1 in a U-shaped bent state and feeding it step by step, is parallel to the needle bed X and is rotatable on a frame 6. It is suspended horizontally.

Below this roller 5, there are two guide bars 7 at the front and rear.
1.72 are horizontally suspended on the same frame 6 in parallel, and the scanning member 2 is mounted on them so that it can slide left and right along it.

That is, as shown in FIG. 4, the scanning member 2 has horizontal through-holes 9 □ provided at two locations in front and behind the traveling base 80 .

9□ is slidably fitted into guide bars 7□ and 7□.

The scanning member 2 has a built-in photoelectric sensor (not shown) at its tip (upper end), that is, a light-emitting element and a light-receiving element that receives reflected light reflected from the card surface and converts it into an electrical signal. A pipe-shaped scanner 10 is provided upright, and as the carriage Y travels, the scanner 10 scans the card 1 horizontally and linearly.

That is, a linking piece 19 made of magnetic material is provided on the traveling base 8 so as to protrude toward the front side (carriage Y side).
The front head of the front end of the knitting machine main body teeth,
It is exposed at the front of the distribution wall 20.

On the other hand, the carriage Y has a magnet piece 22 at the same height as the linking piece 12 at the center of an oblong casing 21 made of non-magnetic material attached to the rear side surface, and magnetic plates 23 on both upper and lower surfaces thereof.
□.

It is installed by adsorbing 23□.

Therefore, when the magnetic plates 230, 23□ on the carriage Y side face the linking piece 19 and attract it while the carriage Y is running, the scanning member 2 runs integrally with the carriage Y. However, when the linking piece 19 reaches the left or right end of the guide groove 20', the magnetic plate 23. ．． The adhesion at 23° ends and the vehicle stops running any further.

That is, the scanning member 2 runs to the left or right integrally with the carriage Y within the length range of the guide groove 20', and is unrelated to the running of the carriage Y outside that range, and always moves to the left. stroke end or right stroke end.

Thus, the card 1 is scanned only within the travel range between the left and right stroke ends of the scanning member 2. Next, the card 1 will be explained.

It has a knitting pattern information recording section 11, which is a section for recording the knitting pattern, and a knitting function information recording section, or function mark, on both the left and right sides of the white surface between the left and right verforations 1'. The function mark entry field 11□113, which is the part to be recorded, should be set in the same color as the emitted light of the light emitting element provided in the scanning element 10, and a color that the light receiving element does not discriminate (for example, when a red light emitting diode is used as the light emitting element). 1' :)
<Of6.6・・3, In the above-mentioned knitting pattern entry field 11□, among the grid dividing lines, the vertical lines are the dividing lines between stitches, and the horizontal lines are the dividing lines between knitting rows. At important points, numbers representing the stitches and numbers representing the number of knitting rows (number of wales) are displayed in the same color as the grid division lines.

To be more specific, knitting pattern entry field 11□ is 1
The minimum division or witness grid corresponds to one stitch, its horizontal arrangement or row corresponds to one knitting needle, and its vertical arrangement or row corresponds to knitting row C-Wale), and the horizontal arrangement or row corresponds to one knitting needle. When knitting a unit pattern with a row of n stitches in one group, the vertical line on the left side and
Regard the vertical lines spaced n lines to the right as the boundary line, and draw a picture (knitting pattern) corresponding to the unit pattern to be knitted between them using an appropriate writing instrument, for example, in black as shown. It is a solid depiction.

For example, when knitting a unit pattern of 24 stitches in a horizontal row by selecting 24 knitting needles as a unit of one group, the left vertical line and the 24th vertical line from that The picture is drawn within the range of the lines.

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

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

Also, left and right function mark entry fields 11□.

113, its horizontal line is on the same line as the horizontal line of the knitting pattern entry field 11□, and its vertical line is parallel to the vertical line of the knitting pattern entry field 111, and the function mark entry fields 112 and 113 are The columns (vertical arrangement) of the witness lattice are aligned on the same line as those in the knitting pattern entry field 11□ and have the same number, but the number of columns (horizontal arrangement) is
For example, while there are 60 knitting pattern entry columns 11, there are 4 function mark entry columns 112 on the left and 4 on the right.

Therefore, the entry field 11□ consists of one function mark display band, and the entry field 113 consists of four function mark display bands.

These left and right function mark entry fields 11□.

Reference numeral 113 is used to fill in (for example, black) the appropriate witness grid when attempting to perform a required function operation. In order to program the feeding of card 1 (selectively apply marks) to the rightmost entry grid row (function mark display band) of the entry grid rows (vertical arrangement) in the function mark entry field 113. In addition, the other three entry grid rows (function mark display bands) other than the entry grid row for the fabric edge in entry section 113 indicate that the thread change is the start and end of the needle selection operation. This is for programming required functional operations other than card feeding.

When the card 1 is loaded on the card feeding roller 5, the function mark entry field 112 in one row of entry grids on the left side corresponds to the stroke end on the left side of the scanning member 2, and the function mark entry field on the right side corresponds to the stroke end on the left side of the scanning member 2. The entry grid row at the right edge of 113 corresponds to the stroke end on the right side, and the knitting pattern entry field 11 and the left and right funxy and Yon mark entry fields 11□ and 113 are scanned by the same scanning member 2. It looks like this.

Then, when the scanning member 2 reaches the left stroke end, the card 1 reads whether there is a mark in the function mark entry field 11□ on the left side, and when it reaches the right stroke end, the card 1 reads the function mark By reading the presence or absence of marks in the entry grid row on the right side of the entry field 113, it is possible to automatically transport the scanning member 2 according to the manner in which the marks are applied only when the scanning member 2 reaches the left or right stroke end. It has become.

Further, as mentioned above, in the knitting pattern entry field 11, a knitting pattern representing the unit pattern to be knitted is drawn solidly, and the scanning member 2 draws this horizontally for each row of grids to be drawn. - It scans in a straight line, and this electrical signal is used to scan card 1 from P to P in the IC diagram in Figure 9.
As shown in (Example when scanning along a line), the result is a square wave corresponding to the form of the knitting pattern in one row of filled grids, that is, the form of one horizontal scan of the knitting pattern. The electrical signals obtained do not have a one-to-one correspondence with the knitting needles to be selected, and the function marks entered in the function mark entry fields 112 and 113 are also similar to the knitting pattern mentioned above, as well as the knitting needles to be selected. 2, and becomes an electrical signal in the same electrical system as in that case.
These electrical signals are converted into digital electrical signals that correspond to the knitting needles on a one-to-one basis by the sampling mechanism described below, and the latter are separated from the former, and each witness grid row is also divided between the latter. This configuration will be explained next.

A flat through-hole 12 is formed between the horizontal through-holes 90 and 9□ in the carriage 8 of the scanning member 2.
A linear encoder 13 in the form of an oblong plate, which is horizontally suspended on the frame 6, is passed through between the guide bars 71 and 7□.

As shown in FIG. 3, the linear encoder 13 has a groove 1 on its rear side edge for sampling the knitting pattern.
4□・・・・・・, in the knitting pattern entry column 1 of card 1
Witness grids are arranged in rows corresponding to the horizontal arrangement of the entry grids in 1□, and three rows of witness grids are provided on the front edge, excluding the witness grid row at the right end of the function mark entry field 113 on the right side. Grooves 143 for sampling the function marks applied to the rows are provided, one groove for each of the three witness grid rows.

The running base 8 of the scanning member 2 has grooves 14□ on the rear side of the linear encoder 13 in relation to its running.
A first sampling pulse generator a1 that optically reads the knitting pattern and generates a sampling pulse for sampling the knitting pattern, and a front groove 143.
. figure).

That is, the grooves 14□ on the rear side are sandwiched between the through hole 12 through which the linear encoder 13 passes, and above and below it.
. . . and the front groove 143 .
0.16□ are placed in the hole, facing each other.

Further, limits are provided on both the left and right sides of the frame 6 at a position corresponding to the left stroke end of the scanning member 2 and a position corresponding to the right stroke end as a means for detecting that the scanning member 2 has reached the stroke end. A switch 171.17r is provided so that when the scanning member 2 reaches the left stroke end, the left pressing plate 181 of the carriage 8 turns on the left limit switch 171, and when the scanning member 2 reaches the right stroke end, , the right pressing plate 18r turns on the right limit switch 17r.

As shown in FIG. Each time the first character grid in column 11□ is scanned, one pulse is output, and the sampling pulse generator a2 outputs one pulse when scanning member 2 scans the right side of function mark entry column 113, as shown in ■ in the figure. One pulse is output every time the other 8 columns of input grids except the witness grid column are scanned, and the left and right limit switches 171.17r are controlled when the scanning member 2 is on the left or When the right stroke end is reached and the witness grid row at the right end of the function mark entry field 11□ on the left side or the function mark entry field 113 on the right side is read, the electric signal r
It will output HJ.

First of all, let's start with the function mark entry field 113 on the right side.
The sampling of the function marks applied to the three witness grid rows C (function mark display band) excluding the rightmost witness grid row (function mark display band) will be explained with reference to FIG. 8.9.

The sampling pulses of the second sampling pulse generator a2j ((■) in FIG. 9) are counted by a ring counter CT.

The ring counter CT is connected to the limit switch 17 on the left side.
It is designed to be reset by the output from 1 and has six output terminals (0) to (5), and when the scanning member 2 is scanning to the right, the above sampling Each time a pulse is input, that is, each time the scanning member 2 scans the three witness grid rows from left to right,
The output terminals of 3) are designed to sequentially output the signals shown in FIG. Each time the scanning member 2 scans the three witness grid rows from right to left, signals are sequentially output from the output terminals (4) to (5) in the same manner as above. .

Therefore, when the scanning member 2 corresponds to the left witness grid column among the three witness grid columns, the ring counter CT is set to the (0) terminal if the scanning member 2 corresponds to the left witness grid column among the three witness grid columns, and the ring counter CT is set to the right terminal. If (5) the terminal produces multiple outputs, and corresponding to the witness grid column in the middle, if it is a left row scan, then α) if the terminal is a left row scan, and if it is a right row scan, ( 4)
If the terminal produces multiple outputs and corresponds to the witness grid column on the right side, if it is a left row scan, (2) the terminal produces multiple outputs,
In the case of right row scanning, multiple outputs are generated from the terminal (3).

The output of the ring counter CT is input to the gate group GT which is supplied with the sampling pulse, and when an output is generated at the (0) or (5) terminal of the ring counter CT (scanning member 2 is approaching the witness grid row on the left side of the above three witness grid rows), the output system of gate group GT (1) is shown in Figure 9 ■
When one pulse shown in (the above-mentioned sampling pulse that passed through the gate) is output, and an output is generated at the terminal (1) or (4) (when the scanning member 2 approaches the middle witness grid row) ) has gate group G
If the output system (2) of T outputs one pulse already shown in the figure, and an output is generated at terminal (2) or (3) (when the scanning member 2 approaches the witness grid row on the right), (in case of 1), one pulse shown in Figure 4 (X) is output from the output system (3) of the gate group GT.

These pulses cause the output of the scanning member 2 to be rHJ
is added to the discrimination circuit SL, such as a D-type flip-flop, which discriminates whether it is "L" or "L", and a mark is applied to the witness grid in the left column of the above three witness grid columns. , the output shown in FIG. When the exchange operation is automatically performed and the witness grid in the middle row is marked, the output system (2) of the discrimination circuit SL produces an output similar to the above. The electric operating element M2, which is connected to the output system, is activated to automatically perform a required function operation different from the one described above, and furthermore, a When the mark is applied, multiple outputs are changed to the output system (3) of the discrimination circuit SL, another electric operation element M3 is operated, and a function operation different from the above is automatically performed. This point is a feature of the method of the present invention.

It should be noted that substantially the same thing as described above can be achieved even if a circuit combining a binary counter and a decoder is used in place of the ring counter CT in FIG.

Next, the transport mechanism (recording medium transport mechanism) of the card 1 will be explained.

First, the mechanical structure thereof will be explained with reference to FIGS. 2 to 7. The card feeder 25 has sprockets 5' on both left and right sides thereof that fit into the left and right perforations 1' of the card 1. 5I is connected to its drive mechanism installed in the control box B, as shown in FIG. 5, so that it can automatically rotate forward or reverse.

The driving mechanism uses an electromagnet 60 as its power source, and when the plunger 61 moves back and forth, a lever 62 connected to a horizontal portion 62' moves around a pivot 63 against a spring 62' as shown in FIG. It is designed to rotate back and forth in the direction of the arrow by the force of the spring.

At the free end of the lever 62, a pivot 64 suspends a normal transfer 9 piece 65□ and a reverse transfer piece 65□, with the former on the rear side and the latter on the front side, and in a symmetrical relationship left and right and front and back. It is.

The forward transfer 9 piece 651 has a pawl 65□' engaged with one 671 of the two ratchet gears 670.67□ fitted on the coaxial shaft 66, and the reverse transfer piece 65 □ is adapted to engage the claw 652' on the front side of the other 672\.

These two sending pieces 65 □, 65 □ are respectively engaged with the ratchet gears 671 and 67 □ or not, so that the card feeding roller 5 is rotated forward or reverse by the electromagnet 60 or is independent of the electromagnet 60. This is done by sliding the card feed switching knob 68 on the operation panel 3 of the control box B back and forth.

That is, a plate-shaped lever 70 is horizontally rotatably supported on an upright shaft 69 below the shaft 66, and the right end of the lever 70 is located between the two feeding pieces 651.65□. The left end of the lever 70 is always engaged with them to maintain a constant distance therebetween, and the left end of the lever 70 forms rising portions 70' and 70# in the front and rear, as shown in FIG.

Then, between the rising portions 70' and 70#, the knob 6
When the lower end of the bent rod 71 attached to 8 is positioned and the knob 68 is set to the neutral position, which is the solid line position in FIG. If the lever 70 is not in its intermediate position, the spring 720
The state is maintained parallel to the axis 66 by the action,
Both sending pieces 65.

652 are set at a retracted position in which neither of them is engaged with the ratchet gears 670, 67□.

On the other hand, when the knob 68 is slid to the rear (left side in Fig. 7),
When the curved rod 71 pushes the rear rising portion 701 backward, the right end of the lever 70 is rotated forward, pushing the reverse feed piece 652 forward, while the ratchet gear 671 of the forward transfer 9 piece 65□ Allows binding to

By energizing and deenergizing the electromagnet 60, the lever 6
2 reciprocates up and down, the forward transfer 9 piece 651 sends the ratchet gear 67□, and the shaft 66 rotates counterclockwise in FIG. Since the gear 74 on the shaft 51 side of the roller 5 is engaged with the gear 74, the card feeding roller 5 rotates in the normal direction, and the card 1 is transferred in the forward direction.

Next, when the knob 68 is slid to the front (right side in Fig. 7),
When the curved rod 71 pushes the front upright section 70' forward, the right end of the lever 70 rotates rearward, pushing the forward feed piece 651 backward, while at the same time displacing the ratchet gear of the reverse feed piece 652. 67□, the card feed roller 5 rotates in the opposite direction to that in the above case, and the card 1 is transported in the opposite direction.

The shaft 5 is connected to the manual feed knob 77 on the operation panel 3 by bevel gears 75 and 76, and the manual feed knob 77 is connected to the shaft 5 with the knob 68 set at the neutral position.
By turning the card 1, the card 1 can be manually transferred in the forward or reverse direction.

The mechanical configuration for card feeding has been described above, and next, the electrical configuration will be explained with reference to FIGS. 10 and 11.

As mentioned above, the automatic feeding of card 1 is performed by the mark made on the entry grid of the function mark entry field 112 on the left side and the mark made on the entry grid of the right edge column of the function mark entry field 113 on the right side. The block diagram in Figure 10 is based on card 1.
is always in a continuous feeding state, and when the scanning member 2 reads the mark, the feeding of the card 1 can be stopped.

Both the AND gate G1 and the Nant gate G2 are connected to the outputs of the limit switches 171 and 17r (the 11th
(Fig. ■) and both of them are turned on, that is, when the scanning member 2 reaches the left stroke end and the right stroke end,
It is designed to open.

When the limit switch 171 or 17r is turned on, the flip-flop FF is set by the output C of the Nant gate G2 (in detail, the output obtained by differentiating it with a differentiator circuit not shown), and the monostable is set via the OR gate G4. Multivibrator MM1 is enabled to operate.

On the other hand, between the Q terminal output of the flip-flop FF, the output of the AND gate G1, and the monostable multipipe rake M
The output ■ (unstable side output) of M1 is applied to the Nant gate G3, and the output ■ of the Nant gate G3 operates another monostable multivibrator MM2, whose output ■ I (unstable side output) is as above. It can be input to Nantes Gate G2.

Monostable multi-bibreak MM1 has its operating time T1
, and the other monostable multi-bi break MM2 is set to T2, so the mono-stable multi-bi break MM operates for T1 hours every 12 hours, so that the electromagnet 60 on the left Unless a mark is made in the function mark entry field 11□ or the rightmost criminal grid row of the function mark entry field 113 on the right side, energization and deenergization are alternately repeated in succession.

On the other hand, when the scanning member 2 approaches the mark, its output I
is the exclusive OR circuit G6 and the above AND gate G□
, the Noritub flop FF is reset, the monostable multi-bi break MM1 stops operating, and the electromagnet 60 is deenergized.

The card 1 is therefore scanned by the scanning member 2. When is at the left stroke end or right stroke end, it is automatically transferred to the marked step, and the amount of transfer is determined by which of the culprit grid rows on both the left and right sides. It is determined by whether the marks are applied to the gratings of the stages, which in turn determines which stages are scanned by the scanning member 2 and which stages are not.

In this way, the automatic music advance of the card 1 is controlled by the marks made on it, but it is further controlled by the manual switch 78 (this operation part is located on the operation panel 3 as shown in FIG. 5). ) is configured so that the monostable multivibrator MM1 is activated only once, so that it can be transferred one step at a time each time the manual switch 78 is operated. By switching the operation section (also located on the operation panel 3) and inverting the reading mark and no mark judgment of the scanning member 2, contrary to the above, the automatic continuous feeding state is set only while marks are being applied. It is also possible to stop it without marking it.

Note that in the block diagram of FIG. 10, the card 1 is always in a continuous feeding state and feeding 9 can be stopped only by operating a mark on the card 1 or a manual switch, but on the contrary, It is also possible to make continuous feeding only by operating a mark or a manual switch so that the continuous feeding is always in the one-step feeding state.

In addition to the electromagnet 60, a pulse motor may be used as a power source for rotating the card feed roller 5.

The reading device A has the above-mentioned configuration, and the scanning member 2 is scanned by the carriage Y running within the guide groove 20'.
scans the card 1, and the knitting pattern on the card 1 is created by sampling with the sampling pulse of the sampling pulse generator a1, as shown in FIG. The digital electrical signals are read as digital electrical signals corresponding to the bits, and the digital electrical signals are stored separately in the storage device MEM (Fig. (details will be described later), and the stored digital electrical signals are stored in the pair of knitting needles when the next right or left operation is performed by reversing the carriage Y. Sorting mechanism CI.

Each time one of the Cr that has an effective sorting effect corresponds to one knitting needle, that is, one bit is read out sequentially according to the traveling timing of the carriage Y, and the bit contents (1
Alternatively, one of the knitting needle selection mechanisms CI or Cr which performs the above-mentioned effective selection function is controlled in accordance with O). Next, such components will be explained.

First, as the carriage Y travels, a fourth timing pulse generating mechanism generates a timing pulse according to the travel timing, that is, a timing pulse for reading out a digital electric signal stored in the storage device MEM.
, 12 to 14.

The current collector assembly IJD mentioned above has two horizontally long metal plates 24□, 24, upper and lower, which are both conductive and magnetic.
By □, the magnet piece 25... and the non-magnetic piece 26...
. . . and the metal plate 240,
The reflector plate 27 is fixed between the magnet pieces 25 and the non-magnetic pieces 26 over the entire length of the back surface between the magnet pieces 242, making the whole into one elongated unit. Horizontally long sheath-like part 21 of the casing 21 attached to Y
21' so that it can slide freely within a predetermined range on the left and right sides, and its back surface (FIG. 14) is exposed through the back opening of the sheath-shaped portion 21'.

The exposed surface (back surface) of the reflector plate 27 is a light reflecting surface, but a large number of rectangular holes 27' forming a non-reflecting surface are formed along almost the entire length of the reflecting plate 27 with a needle. The knitting needles 28 are arranged in rows on the floor X at the same spacing as the pitch of the rows of knitting needles 28.

On the other hand, the distribution wall 20 is equipped with a timing pulse generator (i.e., a light emitting device) that generates timing pulses according to the running timing of the carriage Y by irradiating the reflection plate 27 in front of the distribution wall 20 and detecting the reflected light from the other side. A plurality of combinations of elements and light receiving elements 29 are fixedly arranged at intervals slightly shorter than the length of the reflecting plate 27.

Therefore, a plurality of timing pulse generators 29...
At least one of them always faces the reflecting plate 27, and when the carriage Y is moved, the reflecting plate 27 moves accordingly, and the timing pulse facing it is generated. As shown in FIG. 18, it is clear that a timing pulse is output every time the carriage Y moves by one pitch of the knitting needles.

In this way, the plurality of timing pulse generators 29, which generate timing pulses while taking turns in turn every time the carriage Y travels a predetermined distance, are connected to one output system, and the output For system type, carriage Y is needle bed X
No matter where the timing pulse is located, timing pulses are continuously outputted as if the timing pulses were supplied from one timing pulse generator.

Therefore, the digital electrical signals stored in the storage device MEM mentioned above can be read out in accordance with the traveling timing of the carriage Y, regardless of the position of the carriage Y. Since the digital electric signals are stored separately for the left-hand scanning and the right-hand scanning of the scanning member 2 as the carriage Y moves, they must be read out in accordance with the traveling direction of the carriage Y. Must be.

Therefore, next, a carriage running direction detection mechanism for detecting the running direction of the carriage Y will be explained in order to store the digital electric signal in the storage device MEM and read it out according to the running direction of the carriage Y. .

As mentioned above, the upper and lower two metal plates 241. It is constantly attracted to a horizontally elongated conductive plate 30, which is a conductive material and also a magnetic material, which is attached to the entire front surface of the board through an electrically insulating material.

As described above, the current collector assembly D is fitted into the sheath-like portion 21' of the casing 21 so as to be slidable within a predetermined range, and the current collector assembly D is fitted in the sheath-like portion 21' of the casing 21 so as to be able to move freely within a predetermined range. When the carriage Y is moved to the right, it slides to the right sliding limit position with respect to the casing 21 and then moves together with the carriage Y, and when the carriage Y is moved to the right, contrary to the above, it slides to the left sliding limit position. After being forced to do so, they will move with it.

That is, as the carriage Y is reversed in its running, the current collector assembly D is moved to the left and right with respect to the casing 21.

As shown in detail in FIG. 14 (rear view), this current collector assembly D has a piece 31 on the upper surface of its left end.
1 is fixed to the casing 21, and the piece 311 is fixed to the casing 21.
A switch piece 33 and a terminal 34 having a spring force of 1 are provided inside the cavity 321 that receives the current collector assembly D, and when the carriage Y moves to the left, the current collector assembly D is biased to the right side. Therefore, the piece 311 is separated from the switch piece 33, and the switch piece 33 is separated from the terminal 34, and the switch piece 33 is separated from the terminal 34, resulting in an electrically non-conducting state. However, when the carriage Y moves to the right, Vc and the current collecting assembly IJD are biased to the left. Therefore, the switch piece 33 is pushed by the piece 311 and comes into contact with the terminal 34, so that it becomes electrically conductive.

Therefore, the switch piece 33 and the terminal 34 constitute a kind of limit switch, and thus also constitute a carriage traveling direction detecting means d, which is a contact provided on the right side of the back surface of the casing 21, as shown in FIG. Piece 35
The contact piece 35 is electrically connected to the lead means 36.
However, the front surface of the distribution wall 20 has a conductive plate 3 attached along almost its entire length.
7 (see Figure 2.4),
The carriage traveling direction detecting means d is electrically connected to the necessary electrical and electronic circuits housed in the control box B on the side of the knitting machine main body X, and as shown in FIG. It outputs a binary electrical signal that inverts from "H" to rLJ or vice versa.

Thus, this binary electrical signal causes the storage device M
The EM is controlled, and storage and readout of digital electric signals into it are performed according to the running direction of the carriage Y, and the readout digital electric signals are transferred to the pair of knitting needle selection mechanisms CI, Cr. It is necessary to supply one of the two to have an effective sorting effect.

Therefore, next, the read digital electric signal is sent to the knitting needle sorting mechanism CI, according to the traveling direction of the carriage Y.
Regarding the switch mechanism for switching and supplying Cr, 12th to 1st
This will be explained with reference to FIG.

As mentioned above, the upper and lower two metal plates 2 of the current collector assembly D
4□, 242 is both a conductor and a magnetic material,
It is in constant contact with the conductive plate 30 on the side of the knitting machine main body X, which is also a conductive material and a magnetic material.
In other words, power can be supplied from the X side of the knitting machine body.

These two metal plates 241.24□ have notch holes 24 that penetrate vertically and have a predetermined length on the left and right at two places on the left and right.
1 and 24r, and conductive pieces 381 and 38r embedded in the casing 21 penetrate through them, respectively.

When the carriage Y is on the left, the current collection assembly IJ
By shifting D to the right, the right conductive piece 38r
is engaged with the left edge of the right notch hole 24r, and only that part is electrically connected to the conductive plate 30 on the side of the knitting machine body X. Also, when the carriage Y is in the right row, contrary to the above, the left edge Only the conductive piece 381 is electrically connected to the conductive plate 30.

As shown in FIG. 12, the conductive piece 38r on the right side is connected to the electromagnet 4 of the knitting needle selection mechanism C1 on the left side by the lead means 39.
0, and the conductive piece 38r on the left side is connected to the electromagnet 40 of the knitting needle selection mechanism Cr on the right side by the lead means 41.
There is an electrical connection.

Therefore, when the carriage Y is in the left-hand direction, the digital electric signal from the X-ray of the knitting machine main body is supplied to the electromagnet 40 of the knitting needle selection mechanism Ct on the left side through the conductive piece 38r on the right side,
In addition, in the case of the right row, the electric current is supplied to the electromagnet 40 on the right side through the conductive piece 381 on the left side, and the conductive pieces 381, 38r and the notch holes 241°24r are, so to speak, left and right switches for switching the supply of the digital electric signal. It can be said that they constitute the means El and Br.

Next, the fourth section regarding the left and right knitting needle sorting mechanisms CI and Cr.
Referring to Figures 12, 13, 15, and 16, both have substantially the same structure, although the arrangement of component parts is symmetrical.

The electromagnet 40 mentioned above is installed on a carriage base plate 41, and has magnetic pole plates 42□ above and below it.

422Kit, magnetic conductor 43 integrally molded with enemy magnetic material.
Horizontal portions 43a and 44a of angle 44 are joined from above and below, respectively, and different magnetic poles are excited in both magnetic conductors 43 and 44 by excitation of the electromagnet 40.

On the other hand, a bat guide 45 made of a non-magnetic material is fixed to the lower surface of the carriage base plate 41.

This bat guide body 45 has a bat passage 45a that is long in the left and right directions on its lower surface, and in the bat passage 45a,
The butt 28' of the knitting needle 28 set at the needle selection receiving position can be received through the side cam 46.

The front and back of this bat passage 45a are almost the same as those of the bat 28', and its upper wall surface is a tapered surface where the outer half 45b on the outside as seen from the carriage Y descends inward, as shown in FIG. The inner half 45c is a horizontal plane slightly lower than the normal height of the bat 28' (solid line in FIG. 4).

Therefore, in the process of passing through the bat passage 45a, the bat 28' is gradually pushed down against the leaf spring 47 (FIG. 4) from the middle of the outer half 45b, and is pressed against it at the inner half 45c. , it passes through the bat passage 45a in a state where it fits snugly, and then returns to the normal height again by the action of the leaf spring 47.

With respect to the bat guide body 45 having such a structure, the one magnetic conductive body 43 has a hanging portion 43bJ:, ? Next, the outer lower end portion 43d of the vertical extension portion 43c extending left and right under the carriage base plate 41 is embedded into the thickness of the bat guide 45, and the flat lower end surface of the outer lower end portion 43d is It is flush with the inner half of the upper wall surface of the bat passage 45a, and the interior of the bat passage 45a faces approximately to the center.

Further, in this magnetic conductor 43, the lower edge of the central lower end portion 43e, which is a part of the vertical extension portion 43c and extends inwardly following the outer lower end portion 43d, is gradually inclined downward toward the inside, and The front side of the lower edge is the 16th
Chamfering 43 as shown in the figure (cross section taken along line 00-0 in Figure 15)
It is 6.

The other magnetic conductor 44 has a notch 44d between an outer half 44b and an inner half 44c of the vertical part that hang down from the front end of the horizontal part 44a and extend left and right. The twisted magnetism acts on the outer half 44bK, but hardly acts on the inner half 44c.

This magnetic conductor 44 has its vertical portion hanging down along the rear side surface of a bat guide 45 that is inclined backward inward from the inner end of the bat passage 45a, and guides the magnetism. The outer half portion 44b is located behind the outer lower end portion 43d of one of the magnetic conductive bodies 43 at a middle t on the left and right sides (FIG. 15), which is approximately the same as the arrangement pitch of the knitting needles 280, and is lower than the lower edge height thereof. It hangs down to a position such that the front surface of its outer end faces the rear wall surface of the bat passage 45a.

Thus, the knitting needles 28 with the batts 28' fitted into the batt passages 45a are selected in the following manner.

The bat 28' that has entered the bat passage 45a is moved to the carriage Y.
As it travels, it is gradually pushed down with its front and rear movement restrained, and comes into pressure contact with the lower end surface of the outer lower end 43d of one magnetic conductor 43, and only while passing through the same, the other magnetic conductor 44 The rear surface is pressed into contact with the front surface of the outer half portion 44b.

If the electromagnet 40 is in an energized state during this width t, that is, while the carriage Y is traveling for one pitch of knitting needles, it is possible to A kind of magnetic path is formed between the two magnetic conductors through the butt 28', and the outer lower end 43d of the magnetic conductor 43 is straight, but the outer half 44b of the magnetic conductor 44 is inclined backward. Thus, butt 28' will be biased slightly rearward along its outer half 44b.

As shown in detail in FIG. 16, this rearwardly biased butt 28' connects the rising portion 44e of the inner half 44cc of the magnetic conductor 44 (which is not affected by the electromagnet 400) and the magnetic conductor 43.
By disposing the magnet piece 48 between the rising portion 43f of the magnetic conductor 43, it is attracted toward the inner half portion 44c (the dotted line position in FIG. It rises to a steady height on the rear side of the central lower end portion 43e that is inclined downward, and further advances to push open the opening/closing piece 50, which is closed by the action of the spring 49, to open the rear guide path by a group of cams arranged on the back surface of the carriage Y. It is designed to pass through.

On the other hand, when the electromagnet 40 is in a de-energized state, the butt 28'
is not attracted by the inner half 44b of the magnetic conductor 44, so it advances straight, and is guided by the chamfer 436 on the lower edge of the magnetic conductor 43, biasing it towards the front side of the magnetic conductor 43.
(Position indicated by the dashed line in the figure), it proceeds further and passes through a forward guide path that is different from the case of excitation described above.

Note that a compensating magnet piece 5 is attached to the hanging portion 43b of the magnetic conductor 43.
1 is attached in such a way that its magnetic pole is oriented in a direction that cancels out the magnetic pole of the electromagnet 40, so that the electromagnet 4
This is to eliminate the residual magnetism that exists in the non-excited state after zero excitation, thereby making it possible to perform the sorting operation more reliably.

The knitting needles 28 that have entered the butt passage 45a are subjected to the sorting action one by one as described above, but even if the knitting needles 28 that have entered the butt passage 45a are outside the range of the left and right cursors 41 and 4r mentioned above, In the case where the electromagnet 40 is positioned at , Next, such a configuration will be explained.

In the casing 21 on the back side of the carriage Y, there is a cavity 321 (FIG. 14) on the left side and a similar cavity 32r (FIG. 12) on the right side, where the current collector assembly IJD is located. Piece 3 facing the opposite direction to the piece 311 on the left side of
Position 1r.

- The casing 21 has left and right cavities 32I.

32r earthen wall, and the left and right knitting needle sorting mechanisms CI, C
Left and right movable magnet pieces 521 and 52r are provided on the rear extension line of the sorting point r (width section) so as to be able to freely slide up and down along the respective guide holes.

These two rotating magnet pieces 521 and 52r are the pieces 311 and 31r.
They move up and down, respectively, when the current collector assembly D is in the rightward biased position.
The left side is in a rising state and the right side is in a descending state, and when it is in a left biased position, the relationship is reversed.

On the other hand, the cursors 41 and 4r are mounted on the forward-slanted part of the upper end of the power distribution wall 20 so as to be able to slide left and right, and each has a reed switch 53 on the lower surface, which is connected by a spring. It is electrically connected to a horizontally long conductive foil 55 attached to the entire length of the forward-slanted lower surface of the power distribution wall 20 via a contact piece 54 with force, and both reed switches 53 are connected to the cursor 41.
No matter which position ゜4r is in, the control box B
It is designed to be electrically connected to the necessary electrical and electronic circuits inside the device.

The reed switch 53 is positioned above the traveling line of the movable magnet pieces 521 and 52r on the carriage Y side, and when the carriage Y is moving to the left, the left movable magnet piece 521 is in the raised position. Depending on the case, when it is directly under the left cursor 41, its reed switch 5
3 is turned on and the pulse shown in FIG. The pulses shown in the figure (■) are obtained, and only during the interval between these two pulses is the memory device MEM
The digital electrical signals stored in the K memory are sequentially read out and sorted as described above, and only during this time the pattern is knitted, and the cursor 41°4r constitutes a pattern knitting end indicating means for indicating the pattern knitting end. It can be said that

The mechanical configuration of the knitting machine main body
This will be explained with reference to Figure 7.18.

The binary electric signal from the scanning member 2 (■ in Figure WJ18) and the sampling pulse (■) from the sampling pulse generator a1 are applied to the storage and readout control circuit F, where the signal (■) is sampled and converted to (■). It is a digital electric signal as shown, and its storage device M
Storage in the EM is performed at a predetermined address related to the scanning direction of the scanning member 2, and therefore the running direction of the carriage Y, under control by the storage addressing circuit G and the carriage running direction detecting means d.

That is, the memory addressing circuit G includes an up/down counter and counts the sampling pulses (2) from the sampling pulse generator (a1). Addition and subtraction operations can be switched between the left and right rows of the programming program card 1.
6 related to one stage scanning of the knitting pattern entry field 11, that is, scanning all the filled grids (60 in this example) in one row of the row.
The 0-bit digital electric signal is temporarily stored in the storage device MEM at addresses that are divided into cases where it is obtained by the left row of the scanning member 2 and cases where it is obtained by the right row. .

On the other hand, the stored digital electrical signal is read out as follows.

The pulses ① and ② from the cursors 41 and 4r are generated by an effective needle selection range indicating signal forming circuit H consisting of flip-flops and the like.
As a result, a signal (2) corresponding to the pulse interval from both cursors 41, 4r is formed, and this signal is applied to an effective timing pulse forming circuit I such as a gate circuit. , This is Shikanru 41.
The same number of timing pulses as the 28 knitting needles between 4r
is output one by one each time the carriage Y moves one pitch of the knitting needle.

This timing pulse X is applied to a carriage position detection circuit J that includes an up/down counter.

Thereby, the amount is added or subtracted according to the traveling direction of the carriage Y.

By the way, this detection circuit J has a count value set arbitrarily by a unit pattern knitting stitch number setting means K (this manual operation section is located on the operation panel 3 of the control box B), which is a count value presetting means. (12 in this example), and each time the set number of timing pulses

In other words, this carriage position detection circuit J
It can be said that the knitting needles 28 located between 1 and 4r are coded and numbered repeatedly in a certain direction.

The output of the detection circuit J is supplied to the storage and readout control circuit F as a readout address designation signal for the storage device MEM only while the effective needle selection range instruction signal (2) is being output, and is not stored. In this example, the 12-bit digital electrical signal from O to 11 is read out repeatedly, becomes the signal shown at W, is stored, and is output from the readout control circuit F, after which the effective needle selection is performed. The range indication signal (2) is supplied to a drive signal forming circuit including an AND circuit to which the signal (2) is supplied as a binary electric signal during the rHJ output of the signal (2) through the switch means El or Er,
It is output to the electromagnet 40 of one of the knitting needle sorting mechanisms ci or Cr that performs effective sorting operation.

Thus, the knitting needle 28 between the cursors 41 and 4r is XIV
As shown in the figure, 12 pieces are considered as one block, and they are sorted according to the form of the knitting pattern drawn between the leftmost entry grid of the knitting pattern entry field 11□ and the 912 entry grids on the right side (for example, In FIG. 18, the shaded portions will be deflected backward, and the ones not filled in will be deflected forward.

By the way, it is clear from the above that the knitting pattern entry field 11□ of card 1 is scanned over its entire length on the left and right ends, and all the pits of the digital electrical signal seen in one scan are stored in the storage device MEM. However, the number of bits read out is determined by the unit pattern knitting stitch number setting means K. For example, if it is set to "12", even if there are 12 stitches on the left in the knitting pattern entry field 111. Even if a knitting pattern is recorded on the grid and on the right side thereof, it will be scanned and temporarily stored in the storage device MEM, but it will not be read out as a signal for needle selection. It is.

With the above configuration, it is possible to knit a unit pattern according to the knitting pattern on the card 1, but the main knitting machine further knits the pattern that is actually knitted without changing the knitting pattern. This can be changed by manual operation of the manual operation member on the operation panel 3, which will be explained next.

The pattern left/right reversal means M is configured to reverse the output electric signal from rHJ to rLJ or vice versa as shown by X by switching the manual operation part, and the signal X is used to detect the carriage running direction. The output ■ of the means d is compared (exclusively ORed) with the comparison circuit N, and the addition/subtraction direction of the up/down counter of the carriage position detection circuit J is specified by the comparison signal. It has become.

Therefore, the count value of the carriage position detection circuit J determines whether the carriage Y travels in a certain direction in the above-mentioned relationship XIn or
Even if the knitting pattern on card 1 is the same, the knitted pattern in the case of X[II and key is as if the left and right are reversed. be.

Next, the needle selection mode reversing means P outputs an electric signal similar to that of the pattern left/right reversing means M by switching its manual operation section, and supplies it to the drive signal forming circuit. By operating this means P, it is determined whether the output of the drive signal forming circuit will be like the above-mentioned W or a signal obtained by inverting it.

Therefore, by operating this means P, the front and rear sorting mode of the knitting needles 28 can be reversed, and thereby
It is possible to invert the background pattern of the knitted pattern without changing the above knitting pattern.

In addition, for 1 or more, as formation program card 1,
Although a card in which one entry grid corresponds to one stitch was used, a card in which one entry grid corresponds to a predetermined plurality of stitches may be used as shown in FIG. You can also use pre-printed cards.

Furthermore, knitting patterns and function marks can be created by filling in the card surface.
Even if a card is created by pasting colored paper of a desired shape onto a card, it can be read in the same manner as described above, and such a method is also considered to be an embodiment of the present invention.

Furthermore, in the above, the sampling of the knitting pattern and the function mark is performed using separate sampling pulse generation mechanisms (the groove 141 on the rear edge of the linear encoder 13 and the first sampling pulse generator a1, the groove 143 on the front edge and the 2 sampling pulse generator a2
), but in the method of the present invention, grooves (or slits) for sampling knitting patterns and grooves (or slits) for sampling function marks are provided on the same straight line in a linear encoder. The sampling pulses are read by one reading member (sampling pulse generator) and obtained from the same output system, and the sampling pulses are counted using a counter, thereby generating the sampling pulses for sampling the knitting pattern. A sampling pulse generator for sampling the function mark may be used to perform sampling of both lines in different rows using the differentiated sampling pulses.

Furthermore, the encoder for generating such sampling pulses may be a linear encoder that uses the presence or absence of grooves as a binary signal as described above, a linear encoder that uses optical brightness as a binary signal, or a linear encoder that uses binary signals for optical brightness. Even if a rotary encoder that rotates in relation to the movement of the member 2 is used and its binary signal is read by a fixed photoelectric sensor, sampling pulses cannot be extracted as the scanning member 2 scans. It is possible.

As is clear from the above, the function information reading method of the present invention arranges a plurality of function mark display bands in parallel for programming different knitting operations such as yarn exchange, and each of the function mark display bands is provided with a function mark. Scanning the organization information recording medium configured to selectively display the plurality of function marks by a scanning member across the plurality of function mark display bands, and generating a sampling pulse in synchronization with the scanning of the scanning member, The scanning member reads the presence or absence of a mark on the function mark display band that is currently being scanned, and the same knitting information recording medium can be used to check whether there is a thread change, the feeding condition of the recording medium itself, or the start or end of needle selection operation. Record multiple pieces of function information (with or without marks) that represent various function operations such as
By recording multiple function information in the function mark display band (function mark display band), the multiple function information can be automatically separated and read by the same scanning member, so it is possible to program multiple function operations on the same recording medium. In addition to being able to perform each function operation automatically according to the program,
Moreover, it is economical because all the function information can be read with one scanning member.

Further, the function information reading device of the present invention as set forth in claim 2 has a plurality of seven action mark display bands arranged in parallel for programming different knitting operations such as yarn exchange, and each of the seven action mark display bands is arranged in parallel. A recording medium loading member (card feeding roller 5 in the embodiment) for loading a composition information recording medium in which a function mark is selectively displayed on the recording medium, and a plurality of composition information recording media loaded therein. A scanning member that scans across the function mark display band and outputs an electric signal depending on the presence or absence of the function mark, and a binary signal arrangement that corresponds to the arrangement of the plurality of function mark display bands. an encoder; and a sampling pulse generator for generating a sampling pulse for sampling the electrical signal from the scanning member for each of the function mark display bands by reading the binary signal of the encoder in conjunction with the scanning of the scanning member. Since it uses an encoder to obtain sampling pulses for sampling each function mark display band, it is easy to create the sampling pulses, and it is possible to perform accurate sampling. It is possible.
