Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a means for reading a knitting pattern signal recording medium such as a card on which the knitting pattern signal is recorded, using an optical, magnetic, or electrical reading method, thereby corresponding to the knitting pattern signal. receive an electrical signal (for example, a binary electrical signal),
The present invention relates to a carriage reciprocating type knitting machine that selects knitting needles by controlling a predetermined needle selection member using this electrical signal.

This type of knitting machine cannot be read when the knitting pattern signal does not have a one-to-one correspondence with all the knitting needles arranged in a row on the needle bed, for example, when the entire knitting pattern signal represents a unit pattern. In addition to the electric signal (first electric signal) corresponding to the knitting pattern signal obtained, an electric signal (second electric signal) corresponding to the knitting needles arranged in a row is obtained in relation to the traveling of the carriage,
As a result, it is necessary to control the former electrical signal so that it corresponds to a specific knitting needle at a specific position in a one-to-one relationship.

However, for example, needle selection devices that mechanically select knitting needles in response to the above-mentioned first electric signal are provided on the carriage, respectively, on both the front and back sides of the carriage in the direction of travel, and both needle selection devices A so-called forward or backward needle selection type knitting machine in which only one of them can perform an effective needle selection operation depending on the direction in which the carriage moves, or the reading of the knitting pattern signal recording medium is performed by the movement of the carriage. In relation to the above-mentioned first knitting machine, the above-mentioned first knitting machine is designed to carry out both the leftward movement and the rightward movement by reversing the carriage.
Since the correspondence between the two second electric signals is different, an electric signal (third electric signal) corresponding to the traveling direction of the carriage is further obtained, thereby changing the correspondence between the two electric signals in the carriage's traveling direction. You need to change it accordingly.

Therefore, an object of the present invention is to code a signal for instructing each knitting needle arranged in a row in advance, and read the code signal in relation to the movement of the carriage so as to correspond to each knitting needle arranged in the row. The purpose of this invention is to make it possible to directly obtain the electrical signal as a coded signal.

Therefore, according to the present invention, it is possible to eliminate the need to encode electrical signals corresponding to each knitting needle in a row using a special encoding circuit after reading and obtaining them.

Another object of the present invention is to make it possible to detect a third electric signal for direction determination according to the traveling direction of the carriage using the pre-coded signal (instructing each knitting needle). .

Therefore, according to the present invention, there is no need to separately provide a signal (a permanent signal that is not an electrical signal) representing the traveling direction of the carriage and read it separately from the code signal. The first electric signal corresponding to the knitting pattern signal can be controlled to correspond to a specific knitting needle in a one-to-one relationship regardless of the direction of movement of the carriage.

Hereinafter, the present invention will be described in which a carriage Y is mounted on a groove plate of a knitting machine main body X so as to be slidable left and right, and a predetermined number of needle selection elements, which are needle selection members, are installed on both left and right sides of the carriage Y. Needle selection drums a1, a2 (ultimately a needle selection device that mechanically selects knitting needles) arranged radially are rotatably mounted, and each needle selection drum a1. The gear 2 of a2 is meshed with the gears 41 and 42 that mesh with the rack 3 provided on the rear side upright part b' of the groove plate of the knitting machine main body X, and the carriage Y
In connection with the movement of the needle selection drum a1. a2 rotates, and as it rotates, the needle selection needle
By displacing or not displacing ... by an external force, the needle selection needle ... can be brought into either a state where the knitting needle 5 can be moved or a state where it cannot be moved, and Both needle selection drums a1
．． This will be explained in detail with reference to an illustrated embodiment applied to a hand knitting machine in which only one of a2, that is, the front one according to the traveling direction of the carriage Y, can effectively perform the needle selection function as described above. .

At the rear standing portion b' of the groove plate of the knitting machine main body X and below the rack 3, as shown in FIGS. A signal display member mounting frame 6 having a curved shape is attached.

From the left or right end of the mounting frame 6, as shown in FIG. A plurality of signal display members c can be inserted, and the code signal display member c can be inserted in the inserted state.
can slide left and right along the mounting frame 6.

As shown in FIG. 4, each code signal display member C has, on its white surface, five rows I to ■ on the top and bottom, and 25=32 rows on the left and right, each having a width of 5 knitting needles. By imagining a rectangular section with the same length as the opening, and changing the combination of applying black to the top and bottom five sections in each row on the left and right, or not applying black color, the 32 knitting needles 5 are It is expressed as a 5-bit code signal in which the combination of black and white is expressed in bit units, but two of them are
The bits, that is, the left and right signal arrays of the first stage ■ and the second stage ■, are obtained by reading them.
By examining the correspondence between two series of series binary electric signals, a specific relationship is established so that an electric signal corresponding to the traveling direction of the carriage Y can be extracted.

In other words, in the first column ■, the sections in the first column are white, the second column is white,
The 3rd row is black, the 4th and 5th rows are white, and the black and white are repeated alternately every 2 sections. , followed by black, followed by white in the third and fourth rows, and then black and white alternately repeated every two rows.

On the other hand, on the carriage Y side, a pair of reading members e1. e2 is the left and right needle selection drum a1. They are disposed at both left and right ends of the rear surface of the base plate 7, corresponding to a2, respectively.

Reading member e1. As shown in FIG. 5, e2 is a thick part of the base 8, and in the recess 9 formed on the back surface, a light emitting hole 10 is provided, and five small light entering holes 11 are provided at positions apart from the recess 9. ... are bored in stages at predetermined intervals vertically, and the light source 12 is located deep inside the light emitting hole 10.
In addition, a photoelectric conversion element 13 is installed inside each light entrance hole 11. The light is reflected from the surface of the display member c and enters the five light entrance holes 11, and the five light entrance holes 11 are connected to the code signal display member c. There is a one-to-one opposing relationship with the upper and lower stages ① to ② of the signal array.

If the code signal display member c is inserted into the signal display member mounting frame 6 attached to the knitting machine main body X and the carriage Y is run, both control members e1. It is clear that e2 scans the display member C and outputs a 5-bit parallel binary electric signal corresponding to the code signal displayed thereon.

This parallel binary electric signal is transmitted to the code system corresponding to the knitting needle 5 at the scanning position among the 32 knitting needles 5 located within the range between the left and right ends of the code signal display member c (for example, The knitting needles are 1,0,0,0,0, and the rightmost knitting needle is 1,1°1.1,1).

Thus, the reading member e1 or e2 reads the code signal displayed on the code signal display member c in connection with the travel of the carriage Y, and outputs a parallel binary electric signal corresponding to the knitting needle 5 at the scanning position. However, next we will explain the configuration for controlling the parallel binary electrical signals obtained in this way, and the correspondence between the controlled electrical signals and the electrical signals representing the knitting pattern read in the above manner. A configuration for performing specific needle selection using specific knitting needles within a specific range will be explained with reference to FIG.

Both control members e1. The five photoelectric conversion elements 13 of e2 are connected to the gate G, and the topmost (first stage) of the five photoelectric conversion elements 13, that is, the first stage of the signal array of the code signal display member c. The corresponding one is further connected to the C terminal of a D-type flip-flop FF, which is a means for outputting an electric signal according to the traveling direction of the carriage Y.
Moreover, the one corresponding to the second stage (3) is further connected to the D terminal of the flip-flop FF.

Therefore, the first row (■) of the code signal display member c has black and white alternately repeated every two sections as described above, and the second row (■) is shifted by one section from the first row (■). same as 2
Since black and white are alternately repeated for each section, both control members e1. The first stage photoelectric conversion element 13 and the second stage photoelectric conversion element 13 of e2 are connected to the fourth stage in relation to the travel of the carriage Y.
Square wave signals as shown in the figure are output.

Therefore, while the carriage Y is moving to the left, the output signal of the second stage photoelectric conversion element 13 becomes "L" when the output signal of the first stage photoelectric conversion element 13 falls, so that D The type flip-flop FF outputs "H" from its C terminal, and since the output signal of the first stage photoelectric conversion element 13 is "H" in the right row of the carriage Y, the flip-flop FF outputs "H" from its C terminal. It is clear that outputs "L" from its C terminal.

Therefore, the gate G is connected to the C terminal of the flip-flop FF, and the "H" or "L" level from it is connected to the C terminal of the flip-flop FF.
Depending on the output, the reading member e1. Only one of the output signals e2 on the front side in the carriage traveling direction is allowed to pass through.

That is, when the carriage Y is in the left row, the left reading member e
1, and in the case of the right row, the output signal of the right reading member e2 is passed through.

On the other hand, although not shown, the above-mentioned signal of the knitting pattern signal recording medium such as a card on which the knitting pattern signal is recorded is transmitted to the carriage Y.
In connection with the running of the carriage Y, for example, it is read as a 32-bit serial binary electric signal by the reading means R separately from the above, and is stored in the memory M separately for reading by the left row of the carriage Y and reading by the right row. It is now possible to do so.

The electrical signal representing the stored knitting pattern is transmitted to the reading member e by a reading circuit S which inputs the parallel binary electrical signal from the reading member e1 or e2 through the gate G.
1. e2 whose rank (0 or 1) corresponds to the code of the output parallel binary electrical signal is retrieved, and its readout circuit S is controlled by the output of the flip-flop FF. Due to carriage Y
What is read and stored during the left row of the carriage Y
What is read and stored when the carriage Y is in the right row is read out when the carriage Y is in the next right row operation.

Then, the series 2 read out during the left row operation of the carriage Y
The forward electric signal is amplified by the amplification device AM1, and then input to the left electromagnet device L1 mounted on the carriage Y in correspondence with the left needle selection drum a1.
The serial binary electric signal read out during the right row operation is amplified by the amplifier AM2, and then sent to the right needle selection drum a.
2 is input to the right electromagnet device L2 mounted on the carriage Y.

Therefore, the electromagnet device L1. As shown in FIGS. 1 and 2, L2 transfers its core 14 to the corresponding needle selection drum a1. a2
The needle selection drum a1. Each of the needle selection needles arranged radially on a2 receives or does not receive the magnetic force when facing the core 14, and is therefore either in an operating position where it does not act on the knitting needles 5 or an original position where it acts on the knitting needles 5. In addition to this, the needle selection needle once in the operating position is automatically returned to its original state by a return means (not shown) after the needle selection has been carried out. ing.

In addition, if the signal arrangement of the first stage (3) of the code signal display member c is as described above, the photoelectric conversion element 13 of the first stage is as follows.
Every time the carriage Y moves by 4 pitches of the knitting needle 5, a signal (falling square wave) for detecting the carriage traveling direction is output, and after the carriage Y is reversed, the signal is at least the knitting needle 5.
Since the signal for the above detection cannot be obtained unless the carriage Y is moved by two pitches or more, the left and right reading members e1, e2 cannot be obtained by simply swinging the carriage Y left and right in small increments.
The passage relationship with respect to gate G remains unchanged.

Therefore, by swinging the carriage Y left and right in small increments, the electrical signals representing the knitting pattern stored in the memory M will not be read out randomly, and the carriage Y can be reversed at any position. Also, the electrical signals to be read can be sequentially read out from the memory M.

Now, for example, as shown in FIG. 3, a plurality of code signal display members c are mounted on the signal display member mounting frame 6, and only the one on the left has a blank space 6' between it and the adjacent one. Separate them as far as possible, and insert all the remaining needles with their opposing end surfaces aligned with each other, and place them in the range of Z4 and Z5 of the predetermined number of knitting needles 5 arranged in the range of Z2 to Z6. In order to use a certain knitting needle 5, it is transferred to the needle selection drum a1. Assuming that the knitting needles 5 have been brought to the front position where needle selection is possible according to a2 (therefore, the knitting needles 5 in the range of Z2, Z3, and Z6 are in the rear body needle position),
By reciprocating the carriage Y at least within the range of Z4+Z5, as is clear from the above explanation, within the range of Z5, the one of the left and right reading members e1 or e2 located on the front side in the direction of movement of the carriage Y Parallel 2 corresponding to knitting needle 5 which is subjected to more drawing line selection action
Although the forward electric signal is output, it is not output within the range of Z4, so only the knitting needles within the range of Z5 are subjected to the needle selection action.

Therefore, knitting using knitting needles within the range of Z5 results in pattern knitting, and knitting using knitting needles within the range of Z4 results in flat knitting.

Furthermore, since the electric signal obtained by reading the knitting pattern signal recording medium in which the knitting pattern signal is recorded is a 32-bit serial binary electric signal, knitting by knitting needles within the range of one code signal display member c is possible. A repeating pattern is knitted in which a set of patterns, ie, unit patterns, are used.

Thus, by changing the number of cord signal display members c attached to the mounting frame 6, the number of knitting needles subjected to the needle selection action, and therefore the number of repetitions of the knitted unit pattern, can be changed, and the display members c can be By arranging them apart to create a blank area, it is possible to knit plain only within the area corresponding to the blank area.Furthermore, by preparing multiple display members c with different numbers of coded knitting needles, By exchanging the patterns, the width of a set of unit patterns can be changed.

Note that in the above, the code signal display member c is detachably attached to the knitting machine main body X, but it may also be fixedly attached to the knitting machine main body X. The code signal may be directly transmitted, and the code signal may be expressed by a method other than the black and white combination as described above, for example, with or without holes.

Further, in the above embodiment, the two stages, the first stage (2) and the second stage (2) of the code signal display member c, that is, the 2-bit signal arrays, are arranged in a fixed arrangement relationship, and the carriage Y is arranged between them. Although the signal for detecting the traveling direction can be extracted, it may also be extracted using three or more bits.

As is clear from the above, the knitting machine of the present invention has a code signal that encodes and represents the knitting needles arranged in a row on the main body side of the knitting machine, and at least 2 bits of the code signals are arranged in a fixed arrangement relationship. At the same time, the carriage is provided with reading means (reading members e1 and e2 in the embodiment) for reading the code signal in connection with the movement of the carriage and outputting a parallel binary electric signal corresponding thereto; It is equipped with a means (a D-type flip-flop FF in the embodiment) for inputting a binary electric signal of bits arranged in the above-described fixed arrangement relation among the binary electric signals and outputting an electric signal according to the traveling direction of the carriage. Therefore, the electrical signals corresponding to the knitting needles arranged in a row can be efficiently obtained in relation to the movement of the carriage, and since the electrical signals are already encoded when they are obtained, there is no need for a special encoding circuit. In addition, the code signal itself, which is expressed by coding the rows of knitting needles, is used to extract an electrical signal corresponding to the direction of carriage movement, so a special signal representing the direction of movement of the carriage can be generated. The electric signal representing the knitting pattern is made to correspond to a specific knitting needle in a one-to-one relationship, regardless of the direction in which the carriage moves, without having to read it separately from the code signal. It is innovative as a single knitting machine because it can be controlled as much as possible.
