Description

[Detailed description of the invention] The present invention is an electronic hand knitting machine, in particular, a knitting pattern recorded and displayed on a recording medium such as a card is read as a binary electrical signal and stored in a memory, and the stored binary electrical signal is stored in a memory. The present invention relates to a hand knitting machine capable of reading out signals related to the running of a carriage and selecting needles according to the contents thereof, and electrically changing various modes such as the recording medium transport mode or needle selection mode.

In this type of hand knitting machine, for example, switching from a transfer mode that automatically transfers the recording medium one row at a time to a transfer mode that automatically transfers the recording medium skipping a predetermined number of rows, or leaving the knitting pattern itself unchanged, is possible. You can switch from a needle selection mode that allows the background pattern of the knitted fabric to be the same as the knitting pattern to a needle selection mode that allows the background pattern to be reversed, or change the left and right direction of the pattern of the actual knitted fabric to be the same as the knitting pattern. Normally, a push button switch is used to switch between various modes, such as changing from a needle selection mode that allows you to change the left and right direction of the pattern to a needle selection mode that allows you to reverse the left and right direction of the pattern. If there is only one button, it is impossible to determine which pushbutton switch is for which mode.

Therefore, it is conceivable to display a symbol representing the mode to be switched on the top surface of the pushbutton switch itself, but it is technically troublesome to display it there. Additionally, since multiple pushbutton switches are provided, the installation space must be kept as small as possible, which naturally limits the size of each pushbutton switch. There is a concern that the display is difficult to see.

Now, the various modes mentioned above may be selected one by one, or they may be combined to form a compound mode, and each mode will certainly depend on what it does individually. As this type of hand knitting machine is novel, it is difficult to recognize it, and when it comes to combined mode, it is even more difficult to recognize and easy to make mistakes.

Therefore, in this type of hand-knitting machine, it is not only necessary to simply distinguish which mode each pushbutton switch is for as described above, but also to display what mode it is currently set to. It is important to be able to clearly identify them at a glance.

However, with the present invention, the mode mark that distinguishes which mode each pushbutton switch is used for is placed not on the top of the pushbutton switch itself, but on the side of the knitting machine body in which it is installed. The display on the cover corresponds to each pushbutton switch, which eliminates the above-mentioned concerns, and also lights up to indicate which mode the set mode is currently in. The present invention proposes a hand knitting machine that can prevent malfunctions and also has mode markings and lighting instructions that are easy to see.

The present invention will be explained in detail below with reference to illustrated embodiments.

First, the overall outline of the hand knitting machine to which the present invention is applied will be explained with reference to FIG. 1. On the knitting machine main body X, on the upper cover ₁ behind the needle bed
Push button switch group 2 according to the present invention...
They are arranged in rows, and although not shown, on the lower side of the upper cover 1, the upper cover 1
The knitting machine has a card slot facing at the top and can be loaded so that the knitting program card 3 can be automatically transferred by inserting it from there, and is equipped with a scanning member for optically scanning the information displayed and recorded on it. A pattern scanning device is installed.

Further, although not shown, on the back side of the base plate of the carriage Y, knitting needles of one row of needle beds are installed in response to an electric signal obtained by scanning the knitting pattern on the knitting program card ₃ . A pair of left and right needle selection devices, one of which operates for effective discrimination in the forward and backward directions 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.

The knitting pattern scanning device scans the knitting pattern by automatically scanning the knitting pattern recorded on the card 3 horizontally in a straight line in relation to the left or right row of the carriage Y with its scanning member. It is designed to be read as a series binary electric signal, and this binary electric signal is stored in memory and read out in accordance with the timing of the carriage Y's next right or left row. The knitting needles are supplied to a needle selection device, thereby selecting knitting needles according to the knitting pattern described above and according to the needle selection mode determined by the aforementioned push button switch group 2. It is becoming possible to do this.

Further, this knitting pattern scanning device has an automatic card transfer mechanism that can automatically transfer the card 3 in a direction perpendicular to the scanning line of the scanning member.

Now, as shown in detail in Figure 3, there are a total of seven push button switches 2 in this example, and each has a different function. Speaking of functions, the one on the left _2S is for manually stopping the transfer of the card 3, and the next _{one 21} is for matching the background pattern of the knitted fabric actually knitted with the knitting pattern on the card 3. The next ₂ items are for deciding whether to keep the pattern the same or reversed. ₃ is for making the pattern of the knitted fabric twice as long as the length of the knitting pattern, and the next _2-4 is for making the pattern of the knitted fabric twice as long as the knitting pattern horizontally. The next item 2 ₅ is for knitting a pattern in which a knitting pattern and its mirror image pattern in a symmetrical direction are faced to each other, and 2 ₆ on the right side is used in combination with a so-called rib machine. However, it is designed to perform so-called double knitting, in which the base yarn and the colored yarn are knitted separately for each row of knitting.

Therefore, in the following, when referring to these pushbutton switches individually, 2S is the stop button, _2S is the stop button, and 2S is the stop button.
₁ is the background pattern inversion button, 2 ₂ is the left/right inversion button, 2 ₃ is the vertical magnification button, 2 ₄ is the horizontal magnification button,
2 ₅ will be referred to as the Muki-eye button, and 2 ₆ will be referred to as the Double Ami button.

These pushbutton switches are of the so-called double action type, and are integrated into a keyboard 5 installed on a mounting board 4, as shown in FIG. As shown in FIG. 2, the all-push button switch is constructed by attaching the mounting board 4 to the lower side of the upper cover 1, so that each button part is provided in a recess 1a that is long on the left and right sides of the upper cover 1. Hole 1
It is disposed on the upper cover 1 so as to protrude upward from b.

In the upper cover 1, the front side of the recess 1a in which the buttons are arranged faces forward and slopes downward to form an inclined wall 1c. On the front side of this inclined wall 1c, a mode mark representing the above-mentioned mode determined by operating each pushbutton switch 2 is displayed, and
A light emitter is provided to indicate which mode the device is currently in.

That is, a horizontally long display board 6 is placed in front of the inclined wall 1c.
is attached. This attachment is carried out by fitting the substrate 7, which is integral with the display panel 6, into a shallow recess in the front surface of the inclined wall 1c, as shown in FIG.

The display board 6 has mode marks (letters, numbers, figures, symbols, or a combination of these) representing the modes determined by the six buttons ₂₁ to ₂₆ , excluding the stop button _2S , for each button. It is displayed at the position corresponding to .

Incidentally, in this example, as shown in Figure 3,
For the ground pattern reversal button ₂₁ , a figure 11r representing a normal ground pattern mode in which the pattern of the knitted fabric is the same ground pattern as the knitting pattern and a figure 11i representing a reverse ground pattern mode in which the ground pattern is reversed are displayed. For the left/right reversal button ₂₂ , a figure 12l representing a leftward mode in which the knitted fabric pattern is oriented in the same direction as the knitting pattern, and a figure 12r representing a rightward mode in which the knitted fabric pattern is in the opposite direction are displayed. Also, for the vertical double buttons 2 _{to 3} , a figure 13 representing the vertical double mode in which the pattern to be knitted extends vertically with respect to the knitting pattern, and for the horizontal double buttons 2 _{to 4} , the figure 13 represents the horizontal double mode in which the knitted pattern extends horizontally. For the figure 14 representing the Mukiai button 2 _{to 5} , the figure 15 representing the Mukiai mode in which the pattern to be knitted is the facing of the knitting patterns, and for the double ami button 2 _{to 6} , the so-called A figure 16 representing a double braid mode in which double knitting is performed is displayed.

In addition, below each of these 8 types of figures, "normal", "reverse", "left", "right", "vertical times",
The words ``Horizontal Double'', ``Mukiai'', and ``Double Amikomi'' are displayed.

On the other hand, on the lower side of the display board 6 displaying such a display, eight small window holes 17 are bored in the inclined wall 1c in one-to-one correspondence with the eight kinds of figures described above. Each window hole 17 is provided with the mounting board 4.
A light emitter 18 (in this example, a light emitting diode) attached to the top is exposed from below.

Therefore, when the main hand knitting machine is in the normal background pattern mode due to the setting of the background pattern inversion button ₂₁ , the light emitting body 18 on the lower side of the figure 11r lights up to indicate that it is in that mode. On the other hand, if you press button 2 ₁ from this state to switch to background pattern reverse mode,
The light emitting body 18 on the lower side of the figure 11i lights up to indicate that the mode has been switched to, and if the left-facing mode is set by setting the left/right inversion button ₂₂ , the lower side of the figure 12l The light emitter lights up, and if the button ₂₂ is pressed from this state to switch to the right-facing mode, the light emitter below the figure 12r lights up.

In addition, the vertical multiplier button 2 ₃ , the horizontal multiplier button 2 ₄ ,
Mukiai button 2 ₅ , double ami button 2 ₆ 4
For these, the mode is not normally set for them, and the light emitting body 18 corresponding to them is not set.
remain off, but if you press each of them, the corresponding light emitters 18 will light up to switch to the vertical double mode, horizontal double mode, strong eye mode, and double eye mode.

The six buttons ₂₁ to ₂₆ , the figures representing the eight modes, and the light emitter 18 for instructing them to turn on are in the relationship as described above, and this is the focus of the present invention.

Note that when the stop button _2S is pressed, the automatic card transfer mechanism that automatically transfers the card 3 is controlled, and the automatic transfer of the card 3 is no longer performed, and the card 3 remains stopped at its current position. It's like this. In this state, the light emitter 19 mounted on the mounting board 4 in the same manner as the light emitter 18 lights up.

Further, the automatic card transport mechanism can operate a forward transport mode in which the card 3 can be transported in the forward direction (downward in FIG. 1) and a reverse transport mode in which the card 3 can be transported in the reverse direction, either manually or automatically. Next, a card feed direction switching device that performs such switching will be described with reference to FIGS. 4 to 6.

This card feed direction switching device 20 is installed on the mounting board 4 on the left side of the stop button _2S .

Whether the mode is the forward feed mode or the reverse feed mode is determined by which position the switching member 22, which allows the knob 21 to face upward through the long hole provided in the recess 1a of the upper cover 1, is placed in either the left or right position. It depends on what you have.

That is, the switching member 22 is mounted so as to be movable left and right on an electromagnet 25 having a coil 24 wound around a core 23, and permanent magnets 26l and 26 are mounted on the left and right sides of the electromagnet 25.
It is equipped with r.

On the other hand, a reed switch 27 as a switching means is fixedly installed separately from the switching member 22 at a predetermined position facing the right permanent magnet 26r.

The reed switch 27 is turned on or off depending on whether the switching member 22 is biased to the right and the permanent magnet 26r on the right side is brought closer to the reed switch or by biased to the left and moved away from the reed switch. Whether the card automatic transport mechanism is in the forward direction feeding mode or the reverse direction feeding mode is determined depending on whether it is on or off.

Thus, by picking the knob 21 and switching the switching member 22 left and right, it is possible to manually switch between the forward and reverse modes in the transport direction of the card 3.
It can also be done automatically by controlling 5.

In other words, if the polarity of the current supplied to the coil 24 of the electromagnet 25 is changed, the N and S poles excited in the core 23 will flip from side to side, and the attraction and repulsion of the permanent magnets 26l and 26r to the core 23 will change. This causes the switching member 22 to undergo switching displacement.

Such automatic switching can be programmed by placing a mark on the card 3.

That is, as shown in FIG.
As a result, an electrical signal related to mark reading that causes the card 3 to be fed in the forward direction and an electrical signal related to mark reading that causes the card 3 to be fed in the reverse direction are discriminated.

The two types of electrical signals thus discriminated are input to a drive signal forming circuit 29, converted into a signal sufficient to effectively energize the electromagnet 25, and then input to a drive circuit 30.

By the way, the forward/reverse feeding mode of the card 3 can be identified by attaching a sign plate 3 to the switching member 22 as shown in FIG.
1 is attached, while the inclined wall 1c of the upper cover 1
A window hole 32r in the shape of a downward arrow and a window hole 32i in the shape of an upward arrow are provided in the window hole 32r, and the sign board 31 can be opened depending on which of these windows 32r or 32i the sign board 31 faces.

In addition, in FIGS. 3 and 4, the reference numeral 33 is a light emitter that lights up while the above-mentioned scanning member scans the card 3.

As described above, the hand knitting machine of the present invention has the following effects.

A mounting board is attached to the lower side of the upper cover behind the needle bed, and on the keyboard installed on this mounting board, there are a background pattern inversion button, a horizontal inversion button, a vertical doubling button, a horizontal doubling button, a strong eye button, and a double ami button. Buttons were arranged in a row on the left and right, and these buttons were made to protrude upward from the hole provided in the upper cover, and a light emitting body corresponding to each button was attached on the board, so that these various buttons and The light emitting body can be attached to the knitting machine body at the same time, and electrical wiring is also easy.

At the position corresponding to each button, a unique mode mark such as a symbol or figure representing the mode determined by operating the button is displayed, and
Furthermore, since the light emitting body instructs the light to turn on at the corresponding position, it is possible to prevent erroneous operations due to misidentification of the set mode.

The front side of the upper cover faces forward and slopes downward to form a sloped wall, and a display board is attached to the front of this sloped wall to display the mode mark, and a display board is also displayed on the front of this sloped wall. Since the lighting instructions are given by light emitters on the underside of the board, it is easy to visually see the mode mark and the lighting instructions, and they can be constantly checked because they are in the field of view even during knitting operations.
