Description

[Detailed Description of the Invention] The present invention relates to a pattern weaving device, and particularly to an improvement in the horizontal needle selection mechanism of the jacquard of the same device.

Conventionally, there is a pattern weaving device as shown in FIG. 4, in which when a cylinder 50 holding a pattern paper presses a horizontal needle 51, if there is a hole in the pattern paper, the tip of the horizontal needle 51 passes through the hole in the pattern paper and presses the horizontal needle 51. Since the position of the warp needle 52 remains unchanged, it is pulled up as the knife 53 rises, and the warp threads connected thereto rise. On the other hand, if there is no hole in the pattern paper, horizontal needle 5
1 moves the vertical needle 52 by being pushed by the cylinder 50,
The warp threads connected to the vertical needles 52 do not rise because they are removed from the position where they are applied to the knife 53.

All of these pattern-weaving devices use mechanical operations to transmit motion from the pattern paper to the horizontal and vertical needles, so making the pattern paper is extremely labor-intensive, although an automatic pattern creation system using a computer has been developed. It was something I needed. In contrast, recently, in order to make patterned fabrics without using patterned paper, devices have been developed that electronically control the horizontal needles of jiacards, etc., and horizontal needle selection is performed using electrical signals from a computer-based pattern analyzer. There is a composition.

However, in the case of jiacards with a large number of horizontal needle openings, conventional ones drive all the horizontal needles at the same time, resulting in a complex and large-scale control circuit, which increases manufacturing costs and increases the frequency of failures. There was a drawback.

The present invention aims to solve the above-mentioned problems, and aims to provide a pattern weaving device that has a simple structure and can reliably carry out the pattern weaving process.

The present invention relates to a weaving device having a cylinder which reciprocates in the axial direction of the cross needles to selectively push and move the cross needles, the device being characterized in that a number of cross needle insertion holes are formed in a side wall of the cylinder facing the cross needles, a number of pairs of magnetic bodies are arranged in parallel to the rear of the side wall, an operating rod consisting of a permanent magnet for opening and closing the cross needle insertion and supported midway by the cylinder so as to be rotatable, is interposed between the side wall and the magnetic bodies, the tip of the operating rod is directed toward the cross needle insertion hole and its rear end is inserted between each corresponding pair of magnetic bodies, a head containing an electromagnet which magnetizes each magnetic body is arranged so as to be movable along the magnetic body mounting side of the cylinder, and the electromagnets are energized and the head moves by a control device programmed with the weaving pattern as input data.

Embodiments will be described below based on embodiments shown in the accompanying drawings. FIG. 1 schematically shows the cylinder part of the pattern weaving device according to the present invention, and the cylinder 1 is driven by a driving means (not shown in this example) used in conventional jacquards. It can reciprocate in two axial directions. Reference numeral 3 denotes an auxiliary opening plate that slidably supports both ends of the horizontal needle 2, and the other configurations are the same as those of the conventional jacquard mechanism. Reference numeral 4 denotes a head for operating an operating rod (described later) in the cylinder 1, and the head is reciprocated by a motor 5 in parallel to one side of the cylinder 1, as shown by arrow A in the figure.

FIG. 2 is a sectional view showing the relative arrangement of the cylinder 1 and head 4, and FIG. 3 is a view taken along the - line in FIG. The cylinder 1 has horizontal needle insertion holes 7 in one side wall 6a of the casing 6 forming a rectangular space at a required pitch in the vertical direction of the cylinder 1 as shown in FIG. 2, and as shown in FIG. Similarly, holes are drilled at the required pitch in the longitudinal direction (in the direction of arrow A in FIG. 1). 8 is arranged at a pitch that substantially matches the longitudinal direction of the cylinder 1 in the horizontal needle insertion hole 7 in FIG. 3, and is fixed to the casing 6 so as to penetrate above and below the casing 6 as shown in FIG. The shaft rod 9 is an operating rod that is rotatably attached to each shaft rod 8 at the vertical punching pitch of the horizontal needle insertion hole 7, as shown in FIG. A shaped enlarged portion 9a is formed. In this embodiment, the operating rod 9 is a permanent magnet magnetized so that the enlarged portion 9a side is the south pole and the other side is the north pole.

Furthermore, 10 is a magnetic body made of a pair of iron pieces arranged so as to insert the N-pole side end of each operating rod 9, and as shown in FIG. will be placed halfway through. The end of the magnetic body 10 may be arranged so as to protrude outward from the casing 6.

Next, the head 4 similarly has an iron core 12 in a casing 4a having a rectangular cavity, as shown in FIG. It is formed to have extended portions 12a and 12b that are equal to the distance between both ends of the pair of magnetic bodies 10 such that the N pole side of the magnetic body 10 is inserted therein. Therefore, by moving the head 4 along the cylinder 1 as shown in FIG. 3, both the extension parts 12a and 12b can be brought to a position where they are aligned with the end faces of the pair of magnetic bodies 10. A coil 13 is wound around each core 12, and both form an electromagnet M, whose wiring is connected to a control device (not shown). Therefore, by switching the direction of the current in the coil 13, that is, the positive pole and the negative pole, the extension parts 12a and 12b can be selectively magnetized to the north pole or the south pole. Third
In the figure, the iron core 12 is magnetized so that the extension part 12a on one side becomes the north pole and the extension part 12b on the other side becomes the south pole, and the magnetic body 10 on the operating rod 9 side is also magnetized by the magnetic field. Therefore, the operating rod abutting end 10a' of the magnetic body 10a is magnetized to the north pole, and the operating lever abutting end 10b' of the magnetic body 10b is magnetized to the south pole. As a result, since the base end 9b of the operating rod 9 is magnetized to the north pole as described above, the operating rod 9 rotates counterclockwise in FIG. The insertion hole becomes more eccentric and becomes substantially open.

In addition to the above cases, in Fig. 3, the iron core 1
The second extension part 12a is the S pole, and the other extension part 12b is the N pole.
If it is a pole, the operating rod abutting end 10 of the magnetic material 10h
h' is the south pole, and the operating rod abutting end 10i' of the magnetic body 10i which forms a pair becomes the north pole, and the operating rod 9 is in the state shown in the figure and is arranged to close the horizontal needle insertion hole 7.

The operations of the operating rods 9 in different rows have been described above using FIG. 3, but in actual operation, as the head 4 moves, the operating rods 9 of each stage on the same row shown in FIG. 2 operate at the same time. It is something. That is, by controlling the current to the iron core 12 of each stage by the control device, it is determined whether the operating rod 9 is closed or opened with respect to the horizontal needle insertion hole 7. In this case, the forward and reverse flow of current to each magnetic body 10 is performed by a control device programmed in advance using the pattern as input data. It operates as described above depending on the magnetization form of . When the operation of the operating rods 9 in one row is completed, the head 4 moves to the next column, and in this case as well, the operation of the operating rods in that row can be performed based on input data. During this time, and cylinder 1
Once the reciprocating movement of the operating rod 9 is completed and the magnetic body 10 is magnetized again by the head 4, the operating rod 9
holds its position.

In the above configuration, the magnetization of each magnetic body 10 and the drive of the motor 5 in response to the operation of the operating rod 9 are performed by a control device, but as this control device, for example, a conventionally used electronic longitudinal paper system may be applied. If possible, a position detection circuit for the head 4 may be added to impart the required magnetization to the magnetic bodies in each column.

Therefore, based on the given data, the control circuit operates the operating rods 9 in each column and each stage as the head 4 moves to open or close the horizontal needle insertion hole 7. 1 is reciprocated in the axial direction of the weft needle 2, the weft needle insertion hole 7 opens, that is, the warp thread rises in the position where the operating rod 9 is tilted in Fig. 3, and the warp thread does not rise in the closed state. I can do pattern weaving.

Furthermore, in the subsequent process, by changing the magnetization form of the magnetic body 10 according to the data given as the head 4 moves, the operation of the operating lever can be similarly changed, and work can be performed continuously.

As described above, the present invention has the effect that the pattern weaving process can be reliably performed with a simple configuration.
