DETAILED DESCRIPTION OF THE INVENTION [
The present invention relates to a loom capable of weaving without a needle bar and a body needle. More specifically, the present invention relates to a loom capable of weaving without a guide pin and a body needle, And a drum is provided on the bottom surface of the drum, and a press roller is woven on the front surface so as to press the weft in a warp, so that the drum is supported by the magnet of the drum And the wheel installed at the lower part of the drum is moved over the lower inclination to transfer the weft to the opening part.
Conventionally, in the case of a loom for weaving, a body needle and a weft guiding device are essential. Since the body needle and the weft guiding can not be simultaneously performed, the weaving speed is determined by the speed of the body needle and the weft guiding device.
Therefore, weft guiding devices have been modified and developed in various ways.
In the case of a conventional work machine, a cleanser wrapped with a weft is installed on a shuttle. When the drum is moved between the openings of the upper and lower scissors, a body spit occurs. In the case of a rare weaving machine, When one of the rapiers on the side of the rapier catches the weft and reaches the center of the weaving part, the other side of the rapier arrives at the center of the weaving part so that the other side of the rapier has the weft of one side, , And then the body is salted. In the case of the woot jet loom or the air loom, the weft is fired with water and air, and when the weft arrives at the other side, the body is spit.
Until now, weaving is done by this method. In this case, conventional weaving looms and looper looms can be weaved irrespective of thread thickness, but weft looms and air jet looms having high weaving speed are not suitable for weaving yarns Due to weight and air resistance, it is not possible to weave at the right speed, and when the weft is not sufficiently moved to the other side, the body is stuck, resulting in a defect in the woven fabric.
As described above, since the movement time of the weft and the body needle speed have a close relationship with the productivity improvement, the technology for reducing the movement time and the body needle speed of the weft has been progressed to the minimum. However, In addition, in the case of a wetter jet loom or an air jet loom for fast weft guiding, it is difficult to mass-produce a high-quality fabric at a high speed because it is restricted by the thickness of the yarn and the humidity of the room.
The present invention relates to a method for weaving a high-quality fabric while weaving at a high speed regardless of the thickness of the yarn and the temperature and humidity of the room. The guide frame is fixed to the lower part of the opening part of the weaving part, A magnet (usually permanent magnet can be used) is fixed to the upper part of the bogie, and a drum is installed at the upper part of the bogie guide frame, and a magnet and a roller are installed at the lower part of the bogie.

Unexplained code
(52) comprises a roller guide piece
(54) is a hydraulic pressure passage.
In the present invention constructed as described above, the bogie 4 installed at the lower portion of the weaving portion A is fixed to the band 12, and the band 12 is a power unit of the weaving machine And guided by the guide frame (2).
The drum 16 is fixed to the carriage 4 by the magnet 10 installed on the upper part of the carriage 4 and the magnet 20 installed on the lower part of the drum 16, The roller 16 is also reciprocated so that the roller 16 is provided at the lower portion of the drum 16 so as to reciprocate the drum 16 without cutting the reciprocating motion of the drum 16 and the inclination of the drum 16 ).
Only the wheel 14 mounted on the carriage 4 is supported on the guide frame 2 so that the carriage 4 reciprocates and the carriage 4 reciprocates in the guide frame 2, The magnet 10 installed on the upper part of the truck 2 and the magnet 20 installed on the lower part of the drum 16 are provided with an open part 8 at the upper center part so that the magnetism, Or to change the direction of the magnetic force).
It is preferable that the opening portion 8 is not formed when the guide frame 2 is formed of a non-magnetic material. (Since there is a risk that the roller 18 is detached and may fall into the opening portion 8 of the guide frame 2)
A roller guide member 52 is formed on the upper part of the carriage 4 so that the roller 18 can be moved and moved and a guide bar 28 and a body 30 are installed on the rear surface of the carriage 4, The back surface of the drum 16 is brought into close contact with the body 30 and the guide bar 28 to reciprocate.
The drum 16 is supported on the back and bottom surfaces and fixed by the magnets 10 and 20 so that the drum 16 does not separate from the upper portion of the guide frame 2. [
When the upper surface of the magnet 10 installed on the carriage 4 is set to be N poles in the method of fixing the bogie 4 and the number of the magnets 10 and 20 of the drum 16, When the lower portion of the magnet 20 installed on the lower portion of the magnet 16 is an S pole and the lower portion of the magnet 16 disposed on the lower portion of the magnet 16 is an S pole, Since the magnetic force of the lower floor of the drum 16 and the magnetic force of the upper surface of the drum 4 push each other (the N pole and the N pole, the S pole and the S pole push each other) The magnet 20 of the drum 16 is positioned between the magnet 10 and the bottom of the magnet 10 of the drum 4 and the bottom of the magnet 20 of the drum 16 The upper surface of the carriage 4 and the upper surface of the drum 16 are intended to be joined to each other so that the upper surface of the magnet 10 of the drum 4 and the upper surface of the magnet 20 of the drum 16 are different in polarity, The lower surface of the magnet 20 installed on the carriage 16 and the lower surface of the magnet 10 installed on the carriage 4 are opposed to each other Since the other pole, the drum 16 is fixed without moving left and right.
If the bottom surface of the carriage 4 and the bottom surface of the drum 16 are made of different poles other than the above method, the drum 16 and the carriage 4 are easily adhered. However, in this case, The drum 16 is thrown out from the carriage 4 by an acceleration force according to the weight of the drum 16.
However, when the poles of the bottom surface of the bogie 4 and the top surface of the bogie 16 are set to be the same, when the magnet 20 of the bogie 16 tries to move a little left or right between the magnets 10 of the bogie 4 The upper surface pole of the magnet 10 of the bogie 4 and the lower surface pole of the magnet 20 of the bogie 16 are equal to each other so that the bogie 4 and the bogie 16 always stably adhere at the same position .
Therefore, even if the bogie 4 performs a high-speed reciprocating motion, the bogie 16 is not separated from the bogie 4. [
The roller 18 provided at the lower portion of the drum 16 makes a reciprocating motion without sloping the warp while riding over the lower slope forming the opening and the guide bar 24 provided at the front of the drum 16 is rotated in the drum 16, and the weft yarn is supplied to the opening portion.
A spring 36 is provided to allow the guide bar 24 to turn right and left in order to effectively insert the weft into the opening in the drum 16 and the guide bar 24 for supplying the weft yarn to the side surface of the drum 16 24 may be provided.
A plurality of press-in rollers 22 may be provided as needed to press the weft supplied between the front slopes of the drum 16, and the end of the press-in roller 22 may be provided between the slopes It is preferable that the ends of the press-in roller 22 be too sharp to prevent the inclination from being damaged.
A gripper 34 is formed at both shaft ends of the drum 16 as in the other embodiment shown in Fig. 8, and a cleavage (not shown) is provided on both sides of the drum 16, We can supply weft.
There is an advantage in that it is not necessary to supply the long tailed debris when forming the debris on one side of the loom, as compared with the case where the debris 32 is provided on the drum 16 as described above.
8 of the other embodiment is a shape of the drum 16 in which the gripper 34 and the weft guide bar 24 are provided at the same time.
Since the opening portion 8 is formed when the guide frame 2 is a magnetic body (ordinary metal), it is not only dangerous at the time of high-speed movement of the carriage 4 but also is unsightly. It is good to cover cloth.
As shown in FIG. 9 and FIG. 10, which is another embodiment for reciprocating the carriage 4, hydraulic pipes 38, which operate by a normal hydraulic pressure method, are provided on both sides of the guide frame 3, (40) is provided in the inner hydraulic pressure transmission passage (42) of the guide frame (3), and the bogie (40) is installed to be hermetically sealed against the wall surface of the hydraulic pressure transmission passage (42) of the guide frame (3) When the pressure is released to the other side, the bogie 40 moves to the other side. When the pressure is applied to the other hydraulic pipe 38 and the pressure of the one hydraulic pipe 38 is released, the bogie 40 is moved to one side, Pressure is applied to the one side hydraulic pipe 38 to move the bogie 40 at a high speed and the hydraulic pipe 38 at the other side pulls the bogie 40 while sucking the hydraulic pressure to move the bogie 40 at high speed .
In this configuration, the magnet 10 can be installed on the upper part of the carriage 40, and the weaving can be performed by connecting the drum 16 and the magnet 10 (20). The guide frame 3 is made of a non- The thickness of the lower surface and the side surface of the guide frame 3 is increased to increase the thickness of the lower surface and the side surface of the guide frame 3 to prevent deformation of the guide frame 3, So that the bogie 40 and the drum 10 are firmly coupled to the magnets 10 and 20. In other words,
11, there is formed a hydraulic transfer passage 54 in the lower portion of the guide bar, and the hydraulic transfer passage 42 (see Fig. 11 And the hydraulic pressure passage 54 are connected to each other so that two hydraulic pipes 38 may be installed on one side or a hydraulic pipe may be formed on the center without installing the hydraulic pipes 38 on both sides.
As described above, it is possible to weave the fabric without a needle or body needle. The drum coupled with the permanent magnet directly guides the weft to the opening, and the press roller presses the weft, So that it is possible to mass-produce the woven fabric of good quality without being disturbed by the circumstantial environment (such as humidity temperature) of the weft.
