Description

[Detailed description of the invention] The present invention is a scanning system for a knitting machine that uses a scanning member to scan information such as a knitting pattern recorded and displayed by marking a required information recording medium such as a card and read it as an electrical signal. Regarding equipment.

In this type of scanning device, if the scanning member and the mechanism for driving it are exposed, it is not only unsightly but also susceptible to damage, so it is common to cover these parts with a cover or the like.

However, when doing this, the current position of the information recording medium relative to the scanning line position of the scanning member is not known, so when positioning the information recording medium for the first time, or when you want to arbitrarily set the part to be scanned, etc. , which is inconvenient.

Therefore, the present invention positions the information recording medium at a specific reference position apart from the scanning line position of the scanning member, and then moves to the reference position by performing a simple manual operation such as pressing a button. We have proposed a scanning device for a knitting machine that can automatically transport the finished part to the point where it faces the above-mentioned scanning line position, thereby eliminating the inconvenience in the above-mentioned cases. The present invention will be explained in detail with reference to an illustrated embodiment applied to a machine.

First, the overall outline of the hand knitting machine to which the present invention is applied will be explained with reference to Fig. 1.The knitting machine main body X has its needle bed
On the rear side of 1, a part of the control panel X2 is exposed, and by inserting a composition program card 1, which is a composition information recording medium, into the part facing the control panel X2, the composition program card 1 can be loaded so as to be automatically transferred, and also displayed on it. A scanning device A of the present invention equipped with a scanning member (not shown in FIG. 1) for optically scanning recorded information is installed, and a needle bed x
Although not shown, on the back side of the base plate 2 of the carriage Y that runs on the needle bed A pair of left and right knitting needle sorting mechanisms, one of which operates effectively to sort the knitting needles of the knitting machine back and forth according to the traveling direction of the carriage Y using electromagnetic force, are arranged at a predetermined length apart on the left and right sides.

In the scanning device A, the scanning member is a carriage Y.
By automatically scanning the information recorded on the card 1 horizontally and linearly in relation to the running of the vehicle, an electrical signal corresponding to the information is outputted, and the subsequent processing of the electrical signal is performed electrically. Furthermore, power is supplied to the electrical components of the pair of left and right knitting needle sorting mechanisms by a cord 4 that is passed through a tension member 3 that applies tension to the knitting yarn, for example. By moving the carriage Y back and forth from side to side, knitting needles can be selected according to the knitting pattern.

Now, the mechanical configuration of the scanning device A according to the present invention will be specifically explained with reference to FIGS. 2 to 4.

The entire scanning device A is installed in a frame 5 below the control panel x2. First, the recording medium transport mechanism therein, that is, the mechanism for loading and transporting the organization program 1, will be explained. sprocket wheels 61.6 r on the left and right sides of
It is mounted so that it can rotate integrally.

The sprocket wheels 61.6 r have sprockets 6' that fit into the left and right perforations 1' of the organization program card 1 protruding from the outer circumferential surface at regular intervals, and these left and right sprocket wheels 61.6 card 1 through the pattern card slot 9 facing on the control panel By fitting the foration 1' to the sprocket 6', the sprocket wheel 61.6
r can support the card 1 in a U-shaped folded state, and in this supported state, the card 1 is rotated by a pulse motor a, which is a drive source of a drive mechanism installed on the right side of the frame 5, so that the card 1 can be permuted. It can be transferred in the direction in which the forations 1' are arranged.

That is, the sprocket wheel 61.6r is linked to the pulse motor a by having a gear 10 fitted on its shaft 7 meshing with a gear 11 fitted on the shaft of the pulse motor a.

Therefore, the pulse motor a is capable of forward and reverse rotation, and the forward and reverse directions of the sprocket wheels 6l and 6r are determined depending on whether the pulse motor a is driven forward or backward, thereby sending the card 1 in the forward direction. (Figure 3 bottom)
This determines whether to send it in the opposite direction.

In addition, a part of the shaft 7 is provided with a window hole 12 of the control panel X2.
A finger wheel 13 projecting upward through the control panel is fitted, and by hooking a finger to the finger wheel 13 on the control panel X2 and turning it, the card 1 can also be transferred manually. .

As mentioned before, the card 1 is inserted through the pattern card slot 9 on the control panel It is constructed by arranging it so that an appropriate gap is created between the upright portion 15' at the rear end and the front surface of the raised portion 14, and the card 1 is inserted through the insertion opening 9. The card 1 that has been bent along the guide plate 8 and entered below the control panel X2 is led out to the outside through an exit 16 (FIG. 4) formed at the rear end of the control panel X2.

The upright portion 15 of the transparent plate 15 is provided with a horizontal reference line 15'' serving as a reference means for alignment, and the card 1 is positioned using this reference line 15'' as a reference.

Next, a traveling drive mechanism for automatically traveling the scanning member C to scan the card 1 horizontally and linearly will be described.

Two upper and lower guide rods 17 and 18 are horizontally suspended in parallel to each other on the frame 5, and a scanning member C is mounted on these so as to be able to slide left and right.

That is, the scanning member C has left and right through holes provided in the main body of the running body 19 slidably fitted into the upper guide rod 17, and a bobbin integrally provided on the lower side of the running body 19. 20 is slidably fitted to the lower guide rod 18.

A coil 21 is wound around the bobbin 20, and a horizontally long permanent magnet 22 is placed slightly below the lower guide rod 18 in parallel therewith.

The entire length of the upper side of the permanent magnet 22 is, for example, an N pole, and the entire length of the lower side is an S pole.The lower guide rod 18 is made of a magnetic material, and when a current is passed through the coil 21, the current is , the permanent magnet 22 crosses the magnetic field that is constantly created, and the traveling body 19 is moved by the magnetic force acting between them.
, so that the scanning member C automatically moves along the guide rods 17, 18 to the left or to the right, depending on the direction of the current flowing through the coil 21.

That is, the coil 21 and the permanent magnet 22 are
This constitutes a type of linear motor with 2 serving as a stator.

Therefore, the scanning member C is normally located at the left stroke end (solid line position in Figure 3), but in relation to the travel of the carriage Y (for example, when the travel of the carriage Y is reversed), the left stroke By automatically supplying enough current to the coil 21 to run from the end to the right stroke end (position indicated by the chain line in the figure) and then immediately feedback from the right stroke end to the left stroke end, the left and right It is designed to perform one round trip without interruption at once.

A buffer stopper 23 is provided on the right edge of the frame 5 at the stroke end on the right side with respect to the scanning member C, while a stopper is provided on the upper guide rod 17 at a position corresponding to the left stroke end of the scanning member C. 24 is fixed, but the guide rod 17 is horizontally suspended on the frame 5 so as to be able to slide left and right, and is urged rightward by a spring 26 at its left end, so that the scanning member C is , Stopper 2 during backward movement (leftward movement)
4, but the impact is buffered by the spring 26, thereby preventing reaction (rightward movement) when the stroke end on the left side is reached.

As described above, the running body 19 includes the coil 21 and the permanent magnet 22.
It slides along the guide rod 17.18 due to the magnetic force of the left or right horizontal component acting between the traveling body 19 and the guiding rod 17.18. If there is a gap between the coil 21 and the permanent magnet 2.
If the vertical component of the magnetic force acting between the traveling body 19 and the guide rods 17 and 18 is not uniform in the left and right travel of the traveling body 19, the frictional force between the traveling body 19 and the guide rods 17 and 18 will not be uniform, and the There is a risk that the vehicle may run jerky or stop midway.

Therefore, in order to prevent this, permanent magnet pieces 27 and 27 are provided on the left and right sides of the traveling body 19, which generate repulsive forces in the vertical direction with the permanent magnets 22, so that a constant vertical force is constantly applied to the traveling body 19. ' is fixed.

For example, when the upper side of the permanent magnet 22 is the N pole, the lower side of these magnet pieces 27 and 27' is the N pole.

On the rear side of the scanning member C, as shown in FIG. 4, the card 1 inserted from the pattern card insertion slot 9 as described above is vertically positioned at a height below the control panel X2. In order to scan one side of the card, a reading element,
That is, a so-called charge sensor d is installed, which is composed of a light emitting element and a light receiving element that receives the reflected light reflected off the surface of the card and converts it into an electrical signal.

As the scanning member C travels, its charged sensor d optically scans the surface of the card horizontally and linearly, and hereinafter the charged sensor d will be referred to as a scanning sensor.

Note that the card 1 allows the scanning member C to move forward (rightward) and backward (
It is scanned by the scanning sensor d in both strokes of the scanning member C (left row), but the electrical signals associated with the scanning of the reciprocating stroke are such that only those associated with the forward stroke of the scanning member C are taken out as valid. It has become.

Next, card 1 will be explained with reference to FIG.
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 to a color that is the same as the emission color of the light emitting element of the scanning sensor d and which the light receiving element does not discriminate (for example, the light emitting element is red). This is done by displaying the grid dividing lines in red (in the case of using light emitting diodes) in advance using an appropriate display method such as printing.

In the above-mentioned knitting pattern entry field 1p, the vertical lines of the grid dividing lines that constitute it are the dividing lines between the stitches, and the horizontal lines are the dividing lines between the knitting rows, and below the outside of the field, The numbers representing the stitches are displayed in the same color as the grid dividing lines.

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

For example, when knitting a unit pattern of 48 stitches in a horizontal row by selecting 48 knitting needles as a unit of l group, the distance between the leftmost vertical line and the 48th vertical line It is meant to draw a picture.

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

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

Further, in the function mark entry field 1f, the horizontal line is on the same line as the horizontal line of the knitting pattern entry field 1p, the vertical line is parallel to the vertical line of the knitting pattern entry field 1p, and the function mark entry field is The columns (vertical arrangement) of the entry grid in 1f are arranged 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, 60 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 entry grid when performing a required function operation.In this example, a total of four entry grid columns (vertically The left 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. The other two columns are for programming necessary function operations other than card feeding, such as thread exchange and starting and ending needle selection operations.

As mentioned above, in the knitting pattern entry column 1p of the card 1, the knitting pattern representing the unit pattern to be knitted is drawn solidly, and the scanning sensor d of the scanning member C normally writes this. Horizontally for each grid row -
It scans in a straight line, and the electrical signal associated with one stage of scanning is a square wave corresponding to the form of the knitting pattern in one stage of the grid, that is, the form of one horizontal scan of the knitting pattern. The electrical signal obtained by scanning does not correspond to the knitting needle to be selected in a one-to-one relationship, and the function mark entered in the function mark entry field 1f also does not correspond to the knitting needle to be selected by scanning. These two types of electrical signals are read by sensor d and become electrical signals in the same electrical system, but these two types of electrical signals are separated from each other, and the electrical signals related to reading the knitting pattern correspond to the knitting needles in a one-to-one relationship. The electrical signals associated with reading the function marks are also separated for each entry grid row (vertical row) in the function mark entry field 1f. The sampling mechanism used will be explained.

The frame 5 is located behind the traveling body 19 of the scanning member C.
, the horizontally long plate-shaped linear encoder 28 is connected to the guide rod 17.
．． It is horizontally mounted parallel to 18.

The linear encoder 28 connects a predetermined number (60 in this example) of knitting pattern sampling slits 28p to the knitting pattern entry field 1p for sampling the knitting pattern drawn in the knitting pattern entry field 1p on the card 1.
A predetermined number (four in this example) of function mark sampling slits 28f are provided in correspondence with each entry grid row in an l:1 relationship. The holes are provided in one-to-one correspondence with each entry grid row in the function mark entry field 1f.

On the other hand, on the rear side of the traveling body 19 of the scanning member C, there is a charging sensor for optically reading both the above-mentioned two types of sleeves 28p and 28f, that is, a light emitting element that illuminates the front surface of the linear encoder 28 and its reflected light. A sampling sensor e consisting of a light receiving element that receives light and converts it into an electrical signal is attached.

As the scanning member C travels, the sampling sensor e outputs a pulse corresponding to the slits 28p and 28f, that is, a sampling pulse, and the sampling pulse is the same as the electrical signal related to the scanning of the scanning sensor d described above. As shown in FIG.
The seed sampling pulses, ie the 60 sampling pulses for sampling the knitting pattern and the 4 sampling pulses for sampling the function mark, are arranged to be separated from each other.

In this way, the electrical signals associated with one-stage scanning of the knitting pattern entry field 1p and the function mark entry field 1f are sampled for each entry grid, but such sampling is accurate for each entry grid in relation to the card 1. , the card guide plate 8 has slits 8p and function mark entry fields corresponding in a one-to-one relationship to each entry grid row of the knitting pattern entry field 1p along the scanning line of the scanning sensor d. Slits (8f) corresponding to each entry grid row of 1f in a one-to-one relationship are bored, and the scanning sensor d picks up marks on the card 1 for each slit through these slits. It looks like this.

Therefore, the electrical signals related to reading the knitting pattern are
Each bit corresponds to each filling grid and therefore one knitting needle,
Also, depending on whether or not there is a mark in each grid entry, the binary number 1 is
It is converted into a 60-bit digital electrical signal that determines whether the signal is 0 or 0, and all the bits are stored in a predetermined memory sequentially from left to right.

Then, the stored digital electric signal is transferred to the carriage Y.
Carriage Y
It is supplied through the cord 4 to one of the electromagnets of the knitting needle selection mechanism that is provided on the back side of the knitting needle selection mechanism that is to be operated effectively, so that the knitting needles are controlled according to the content of each bit of the read digital electric signal. The number of bits read out is determined by the number set with the needle selection unit number setting dial 29 provided on the control panel X2 (turn the dial 29). (The readout circuit of the memory that stores the digital electrical signal is controlled), and the set number of bits are read out repeatedly, and the number of needle selection units is determined by this.

Next, the electrical configuration of the scanning device A will be explained with reference to FIGS. 5 to 7.

When knitting is performed by operating the carriage Y, an electric signal obtained by detecting the reversal of the carriage Y or detecting that the carriage Y approaches a predetermined member on the needle bed X1 is used. According to the electric signal obtained by the above, the card feed command circuit 30 shown in FIG. 5 outputs a card feed command signal as shown in FIG. 6 each time the above detection is made.
As a result, the pulse generator 31 outputs, for example, one pulse each time as shown in FIG.
When driven, the card 1 is transferred one step at a time in a predetermined direction by marking the function mark entry field 1f, and the scanning command circuit 33 is configured to move the card 1 step by step in a predetermined direction by marking the function mark entry field 1f. Each time the pulse output is completed, a scanning command signal is output as shown in III, and this causes the scanning member drive circuit 34 to perform the scanning every time the card 1 is transferred in one stage as described above, as shown in IV. The member C is driven to reciprocate all at once.

However, when the button 35 (FIG. 2), which is an example of a manual operation member provided on the control panel X2, is pressed, the card 1
By placing a mark in the function mark entry field 1f, it is ensured that the paper is automatically transferred by a predetermined number of stages in the opposite direction (upper side in FIG. 3), regardless of the predetermined transfer direction.

That is, the scanning sensor d reads a mark for determining the feeding direction in the function mark entry field 1f, and the feeding direction instruction circuit 36 moves the mark in the determined direction as shown in FIG. 7 II. The feed direction control circuit 37 outputs a corresponding binary electric signal, and the feed direction control circuit 37 also outputs a normal feed direction instruction circuit 36 as shown in
Therefore, the electric signal is outputted as it is to the pulse motor drive circuit 32 without any change, and as a result, the card 1 is transferred in the direction according to the mark. When you press 35, the electrical signal based on it changes from H to L as shown in ■.
This state will continue until the button 35 is pressed next, and during this time the feed direction control circuit 37 will control the feed direction control circuit 37 regardless of whether the electric signal from the feed direction instruction circuit 36 is from H to L.
A signal to move the card 1 in the reverse direction (upward) is output.

On the other hand, when the button 35 is pressed for the first time, the signal (■) is differentiated as shown in III by the differentiating circuit 38, and the pulse generator 39 is driven by the differentiated signal to generate a predetermined plurality of pulses. The above pulse drive circuit 32
As a result, the card 1 is always transported in the reverse direction by a predetermined number of stages.

This transfer amount is set so that the portion of the card 1 that was facing the scanning line of the scanning sensor d is aligned with the reference line 15'', which is a position that can be seen through the upright portion 15' of the transparent plate 15. It is.

Thus, the amount of transfer is determined by the number of pulses generated by the pulse generator 39 per operation, which is ten in this example.

By pressing the button 35 as described above, the reference line 1 is
In order to return the scanned portion of the card 1 that has been displaced to the point where it coincides with the scanning line 5' to the original position facing the scan line, the button 35 can be pressed again.

That is, when the button 35 is pressed, the electric signal based on the button 35 is restored from L to H as shown by I, so that the pulse generator 39 outputs 10 pulses again, and the pulse motor drive circuit 32 operates.

On the other hand, the pulses from the pulse generator 39 are sent to the counter circuit 4.
0, and the counter circuit 40 outputs a signal H as shown in IV from the time of inputting the first pulse until counting the 200th and final pulse.

The feed direction control circuit 37 inputs the output of the counter circuit 40, and while the signal ① changes from L to H and the signal IV changes to H, that is, when the button 3
After the second operation of 5, the pulse generator 39 changes to 10.
Until the output of the pulses 1 to 1 is completed, a signal H is supplied to the pulse motor drive circuit 32 to move the card 1 in the forward direction (downward) as shown in ①I.

In this way, the card 1 is automatically returned and transported in the forward direction until the portion that coincides with the reference line 15'' again faces the scanning line of the scanning sensor d.

When this automatic return transfer is completed, the counter circuit 40
When the output IV changes from H to L, the scan command circuit 33
By outputting a scanning command signal as shown in (1), the scanning member drive circuit 34 operates as shown in (2), and the reciprocating movement of the scanning member C is automatically performed only once. There is.

Further, the output IV of the counter circuit 40 is inputted to a display means 41 such as a light emitting element provided on the control panel X2, and the part of the card 1 that is about to be scanned is
During the period from when the above-mentioned displacement starts based on the operation of the button 35 to when the display means 4 returns to its original position,
1 lights up, which allows you to confirm that card 1 is in the displaced state described above, and also lets you know that you should not perform carriage operations during this time. There is.

However, when the button 35 is pressed and the card 1 is automatically transferred in the opposite direction by a predetermined number of stages and stopped, by looking at the side of the card along the reference line 15'' through the upright part 15' of the transparent plate 15, You can see that this is the part that will be scanned, and press button 35.
By pressing again, card 1 can be automatically returned to its original state.

The above is a case where the scanning part is checked after Card 1 has already been loaded. However, when positioning Card 1 for the first time when loading Card 1, before inserting Card 1 into the pattern card slot 9, first press the button. 35 to supply the first ten pulses from the pulse generator 39 to the pulse motor drive circuit 32 and the sprocket wheel 6.
1.6 Let the R rotate 10 pitches, insert the card 1, feed the card 1 with the finger wheel 13, align the first row to be scanned with the reference line 15'', and then press the button 35. As a result, the circuit shown in FIG. 5 performs the same operation as the second button operation during the scanning placement confirmation described above, and the card 1 is placed at the reference line 15''. The stage that was aligned with the stage is automatically transported in the forward direction until it reaches the scanning line position of the scanning member C, and when it stops there, it is automatically scanned by the scanning member C, and this point is the emphasis of the present invention.

Although one embodiment of the present invention has been described above, the present invention is not limited thereto.

That is, in the above example, the pulse motor a is used to rotate the resprocket wheel 61.6 r in the forward and reverse directions, but two electromagnets, one for forward rotation and the other for reverse rotation, are prepared and these can be selected. The card 1 may be transferred in the forward or reverse direction by operating the card 1 in a forward or reverse direction.

In addition to the sprocket wheels 61 and 6r, the feeding member that directly supports and feeds the card 1 may be a belt having a protruding sprocket.

As is clear from the above description, according to the scanning device of the present invention, the information recording medium (the organization program card 1 in the embodiment) is placed at a specific reference position (the reference line in the embodiment) that is distant from the scanning line position of the scanning member. 15"), and by performing a simple manual operation such as pressing a button, the part facing the reference position can be moved upward until it faces the scanning line position, and information recording. This makes it possible to easily position the medium.
