Pile pattern feeder supply control circuit device of circular knitting machine

1 is a circuit diagram of the present invention.

2 is an explanatory diagram of the present invention.

The present invention relates to a pile pattern yarn supply control circuit device of a circular knitting machine which is capable of automatically knitting natural pile three-dimensional patterns by supplying pile yarns of various colors to the knitting needles by electronic control in pile double-sided circular knitting machines. .

The present invention is to install a pair of pile file pattern yarn feeder for each color installed at a certain interval around the cylinder of the circular knitting machine, and the terminal plate is formed in parallel with the number of the number of apostles of the needle of the circular knitting machine Each of them is formed in a number so that the contacts installed at the knitting position of the circular knitting machine are opened by a cam mechanism, and the number of course of the letter of the letter forming the pattern of the switch plate on which the transistor switch circuit is formed according to the number of pattern yarn supplying devices. Form a connection between the terminal plate and the switch with a permutation corresponding to the pattern, and then rotate the rotary cam to knit the pile paper. Each time the cam pushes the knitting needle, the contact of the terminal plate is folded, but the relay of the pattern feeder connected to the pattern is the same By supplying the thread of the corresponding color to the knitting needle by interlocking the pattern yarn feeding device, the natural color three-dimensional pile pattern is That can be braided in a braid pattern in which the same image file of a phase inversion (全長) haryeoneunde able nophil than the commercial value has its purpose.

Conventional circular knitting machines, especially double-sided pile circular knitting machines, are mainly knitted in a single color, and when various yarns are used to supply different colored yarns to each yarn, they are simply braided with simple stripes of horizontal hospitality, and have various arbitrary colors. There was a drawback that the natural pattern of the paper could not be braided and therefore the product value of the pile paper was not high.

The present invention is to form a color pile pattern yarn feeder for each color in the position of the known apostle without structural improvement or change of the circular knitting machine itself, the terminal plate, switch plate and relay which can control the pile pattern yarn feeder according to the order of knitting needle A pile is installed to connect the terminals of the terminal plate and the terminals of the switch plate in an appropriate arrangement according to the pattern indicated on the design paper, so that the pile pattern yarn supply device operates automatically according to the order of the connection and automatically the natural solid of the collar. It is possible to braid the pattern described in detail by the accompanying drawings as follows.

Each contact (a ₁ ... n) folded by the cam (3) for each position of the knitting needle (2) of the rotary cam (1) of the circular knitting machine is mounted in the number of needles, respectively, and each of these contacts is connected to the number of apostles. (b ₁ ... n) are juxtaposed with the terminal plate (B ₁ ... n) to form a sink in the needle each point (a _l ... n) then the wiring and the terminal plate (B ₁ ... n) and for the file pattern yarn fed toward apparatus for Switch plates Q ₁ ... Qt, in which the transistors TR _l switch circuit and the terminals P ₁ ... n are arranged in parallel with each other, are formed side by side in the number of courses (stages) of the piled paper in which the pattern is repeated up and down. The output terminals of the switch plates Q ₁ ... t are connected to two sets of relays L ₁ ... n of the feeder for cutting and cutting each pile through the rP crater circuit F of the transistor TR ₂ . each hayeoseo gyeoljeop is separate from a switch circuit of the switch plate is able to operate only a pair of the relay and the movable contact (K ₁₎ is formed once copper plate 4 is provided with It was placed a position plate (Q ₁ ... t) contacts a sink of (K) in a circular rotary cam (1) by the signals applied through the conductors formed on the end terminal plate (Bn), each round of jeonhalttae transistor (TR ₃₎ As the SCR is triggered and the relay LR is operated while the operation is performed, the movable contact point K ₁ folds one contact point K one by one to sequentially shift the operation order of the switch plate. It is possible to braid the pattern by controlling electronically.

In the drawings, reference numeral T denotes a transformer and Dn denotes a rectifier circuit.

Referring to the operation and effect of the circuit device of the present invention configured as described above are as follows.

First, each terminal (b ₁ ... n) and the switch plate (Q ₁ … t) of the terminal board (B ₁ … n) in the order required for the supply of the patterned yarns according to the knitting order of each knitting needle of the design paper on which the pattern to be braided on the pile paper is drawn. Selectively connect the conducting wires between each terminal (P ₁ … n).

This is equivalent to storing the electrical signal to the switch plate by the color of the pattern, while 1 terminal board (B ₁₎ is the (a ₁₎ Contact 1 jeopri during the modulation of the number 1 needles in the terminal plate (B ₁₎ 1 Terminals b ₁ ... N of the number of slopes are electrically interrupted, and when the last needle is modulated, the last contact an is folded and electrically interrupted at the last terminal plate B n.

Since the movable cam K ₁ of the rotary plate 4 is connected one by one in turn every rotation of the rotary cam 1, the movable contact K ₁ of the rotary plate 4 is connected when the rotary cam 1 rotates once. when power is supplied to the # 1 switch plate (Q ₁₎ only a transistor (TR ₁₎ is operated, only the switch plate (Q ₁₎ once the rest of the switch plate is not value operation rotating the cam end of the handle to rotate at a predetermined rotational speed During the rotation of the course, the last switch plate Qt is operated by supplying power to the transistor TR ₁ , and each switch plate operates one by one each time the rotary cam rotates.

However, at this time, the entire circuits of the switch plates Q ₁ ... t are not operated simultaneously, and current is supplied to the base side only to the transistor TR ₁ to which the terminals b ₁ ... n of the terminal plates B ₁ ... n are connected. And a pair of relays L ₁ (L ₁ ') of the pile pattern feeder. By random operation of (Ln) (Ln '), two or three strands of a designated color are arbitrarily supplied and cut to braid a solid three-dimensional pattern.

For example, in FIGS. 1 and 2, the first terminal (b ₁ ) of the first terminal (B ₁ ) is connected to the first terminal (P ₁ ) of the first switch plate (Q ₁ ), and the first terminal (B _1). The last terminal (bn) of) is connected to terminal 1 (P ₁ ) of the last switch board (Qt), and the third terminal (b ₃ ) of the last terminal board (Bn) is 2 of the switch board (Q ₁ ). one terminal (P _2), the cam by a connection, and if the fifth terminal (b ₅₎ of the terminal plate (Bn) hayeotdago connected to the last switch plate (Qt) 2 times, the terminal (P ₂₎ of the rotation cam (1) is rotated ( 3) When this needle (2) is pushed to connect the contact point (a ₁ ), the terminal connected to the number 1 terminal plate (B ₁ ) is grounded and the power is supplied, and the number 1 terminal (b ₁ ) terminal is the number 1 switch plate (Q). ₁₎ l time port (P ₁₎ the first time the transistor (TR ₂₎ in the operation as a relay circuit (F) of the transistor (the bias power is supplied to the base of TR _1), a transistor (TR ₁₎ of the terminal through the By operating the relay (L ₁ ) (L ₁ ') connected to the file of the color By interlocking the pattern yarn feeder, the color yarn is supplied and cut only in the first yarn, and the basic yarn is not supplied to the other yarns.

At this time, the last terminal (bn) of the _first terminal plate (B ₁ ) is connected to the last switch plate, but there is no operation because there is no power supply to the switch plate.

Subsequently, when the rotary cam 1 of the circular knitting machine makes one rotation and connects the last contact an by the cam 3, power is supplied only to the terminal plate Bn connected to this contact an and is connected to terminal 5 (b ₅ ). Although the base current is applied to the transistor TR ₁ through the _second terminal P ₂ of the last connected switch plate Qt, there is no collector current, but it does not operate, but the first switch plate connected to the third terminal b ₂ ( As power is supplied to terminal 2 (P ₂ ) of Q ₁ ), the transistor (TR ₁ ) operates and its output passes through the second transistor (TR ₂ ) of the relay circuit (F) to the second relay (L ₂ ). (L ₂ '), the operating and supplying the file corresponding saeksa in the three pattern yarn supply apostle that works with the relay, and thus the rotary cam (1) when the first rotation relay (LR) is to operate the movable contact (K ₁ ) Move one contact point, and when the operation of the last switch plate (Qt) is completed by repeating this operation, the pattern of one pattern becomes It is returned to the switch plate once again, and weaving the color solid pile pattern automatically repeatedly.

As described above, the present invention is not limited to a single pattern because it is possible to braid a pattern by automatically supplying a colored pattern pile yarn during knitting of the circular knitting machine by connecting the terminal of the terminal and the switch plate according to the pattern. Natural pattern can be variously braided and new pattern can be infinitely reproduced by changing combination of terminal plate and switch plate, so that the product value can be increased compared to the conventional forged double sided pile paper, and the scope of use can be greatly expanded. Has the effect.
