Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a machine that performs processes related to warp operations based on predetermined weaving pattern information, typically a machine such as a jacquard machine or a pattern punching machine for a jacquard machine. This invention relates to a device that translates weave pattern information into mechanical motion, which is applied to such machines to provide weave pattern information via electrical signals to control operations related to warp thread manipulation. .

BACKGROUND OF THE INVENTION Conventionally, pattern analyzers have been developed for processing textile pattern information related to the manipulation of warp yarns into signals using computers during textile weaving, and have already reached the stage of practical use. Further, attempts have also been made to directly control the operation of a Jiya Guard machine, etc. by giving such signal-processed weave pattern information as an electrical signal to a machine such as a Jiya Guard machine. A device is needed to translate this into a physical action. The most common way to implement this device is to use an actuator actuated by the electrical excitation of an excitation winding (solenoid) as an element of the mechanism that converts an electrical signal into mechanical action. Previous attempts have also mainly been made using such methods. However, with conventional devices of this type, they are bulky, have complex structures, are extremely expensive, do not operate smoothly or reliably, and have poor operational responsiveness. have some unresolved drawbacks, such as poor performance or inability to drive at high speeds,
It had not yet reached the stage of true practical application.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a device for translating weave pattern information into mechanical motion, which eliminates the above-mentioned drawbacks as much as possible.

That is, the present invention comprises a signal output means for extracting weaving pattern information as an electric signal, and a mechanism for converting the output electric signal from the output means into a mechanical operation, and the conversion mechanism converts the mechanical operation into a warp operation. The means for transmitting information includes a plurality of actuators each interlockingly connected to a plurality of input members,
The actuator has a magnetic body, an excitation winding wound around the magnetic body for selectively exciting the magnetic body by the output electric signal, and a permanent magnet structure disposed at a fixed position. The permanent magnet structure has a plurality of opposing pairs of N
A pole face and an S pole face are provided such that the pair corresponds to each of the actuators, and each of the actuators is provided with a magnetic body in the N direction of the permanent magnet structure.
It is possible to occupy two positions depending on the excitation polarity, a position where it is attracted to the pole face and a position where it is attracted to the S pole face, and by selecting these two positions, the warp operation information can be selected. The device is a device for translating weave pattern information into a mechanical motion, and in particular, the magnetic material in each actuator is attracted to the N-pole surface and the S-pole surface of the permanent magnet structure. The part is covered with a coating material made of non-magnetic material,
When the magnetic body is attracted to either the N-pole surface or the S-pole surface, the magnetic body does not come into direct contact with these pole faces but through the covering material made of the non-magnetic material. This is a device that translates weave pattern information into mechanical motion.

In this invention, the output means for extracting the weave pattern information as an electrical signal is generally a weave that has been converted from a picture into a signal by a computer-based picture decomposition device or the like and recorded on an appropriate material such as a magnetic tape. It consists of a pattern information recording means and a means for reading information from the recording means and reproducing it into an electrical signal. However, it is also possible to directly extract the weave pattern information as an electrical signal through a pattern decomposition device without using a recording means. As recording means, in addition to magnetic tape, floppy disks, perforated tapes, perforated disks, and even conventional patterned paper can be used.

According to one embodiment of the present invention, a means for transmitting a mechanical operation as warp operation information in the present invention and a plurality of input members in this means are connected to a heald operation mechanism of a jacquard machine in a loom and a heald operation mechanism of a jacquard machine in a loom. It is constructed with a cross needle as a control element for heald operation in the mechanism. In this case, it is possible to weave a fabric without using pattern paper based on the weave pattern information.

According to another embodiment of the present invention, a means for transmitting a mechanical operation as warp operation information in the present invention and a plurality of input members in this means are configured to include a pattern paper punching machine (punching machine). It is composed of a drilling drive mechanism and wires and horizontal bars as control elements for drilling operations in this mechanism. In this case, it is possible to perforate a patterned paper for a conventional jiacard machine based on the weave pattern information.

In this invention, it is very preferable that the magnetic body in each actuator is in the shape of a rod whose rear part is pivoted and whose tip end is an attractive part for the N-pole surface and the S-pole surface of the permanent magnet structure. An excitation winding is wound around at least a part of the outer periphery of the rod-shaped magnetic body excluding the tip, and the tip of the rod-shaped magnetic body is formed thinner than the other part, and the tip of the rod-shaped magnetic body is formed to be thinner than the other part. A covering material made of a non-magnetic material is applied in the form of a cylinder or a cap.

The coating material made of a non-magnetic material to be coated on the magnetic material of each actuator is selected from metals and other suitable non-magnetic materials, and is typically stainless steel, non-magnetic steel, or ceramic. However, it is more preferable that the non-magnetic material is non-conductive, and in terms of durability, it is preferably as hard and durable as possible. In this sense, it is most preferable that the non-magnetic material is a non-conductive, hard ceramic.

Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, there is schematically shown the construction of a preferred embodiment in which the device of the present invention is applied to a Jacquard machine. In the figure, the main components of a conventionally well-known jiacard machine are collectively indicated by number 1, and the mechanical part that converts an electrical signal into mechanical operation is indicated by number 10.
Further, a signal output means for extracting the weave pattern information as an electrical signal is indicated by the reference numeral 22.

The jacquard machine 1 has a plurality of vertical needles arranged and supported on a bottom plate 6, the upper end of which can be moved up and down by hooking the knives 3 of a vertically movable knife box 2 as appropriate, and a lower part of each vertical needle having a warp shedding operation. A cord 5 connected to the controlling heald is connected, and a length is provided for engaging and pushing each vertical needle 4 appropriately in order to engage and release the upper end hook portion of each vertical needle 4 with the knife 3. A plurality of horizontal needles 7 which are movable in the horizontal direction are arranged and supported by a rear opening plate 8 and a front auxiliary opening plate 9.

The conversion mechanism 10 is disposed at a position facing each of the horizontal needles 7 at the front end of each of the horizontal needles 7 immediately in front of the auxiliary opening plate 9 at the front of the jacquard machine 1 . Therefore, the conversion mechanism 10 is disposed in place of the paper cylinder at the position where the paper cylinder should originally be installed.

The conversion mechanism 10 includes a box-shaped mechanism frame 11 that is approximately the same size as the original paper cylinder.
The frame 11 is connected to the horizontal needle 7 by a button 12 as shown in the figure, which is driven from the crankshaft of the loom by a method such as a rod drive, shaft drive, or chain drive, in the same way as the original paper cylinder. The reciprocating motion of the horizontal needle 7 in the length direction for pushing the needle 7 is mechanically performed.

At the rear of the inside of the frame 11, magnetic bodies 31 and magnetic bodies 31 are arranged so as to correspond to each horizontal needle 7 at a pitch equivalent to that of the horizontal needles 7 according to the arrangement of the horizontal needles 7. A plurality of movable actuators 1 comprising an excitation winding (solenoid) 32 wound around a magnetic body 31 for selective excitation by an electric signal.
3 are arranged and equipped opposite each horizontal needle 7. The tip of the magnetic body 31 of each actuator 13 is exposed into each corresponding space of the permanent magnet structure 14, which is formed into a shelf shape and arranged at a fixed position corresponding to the arrangement thereof. The tip of the magnetic body 31 of each actuator 13 is closely opposed to the rear end of each push rod 15 that mediates the pushing of each horizontal needle 7 arranged further forward in accordance with the arrangement thereof. Each push rod 15 has a front plate 17 elastically supported on the front part of the frame 11 at appropriate intervals so as to be accessible by a spring 16.
It is slidably inserted through the. Front plate 1
A slightly thickened cap-shaped head 18 is formed at the tip of each push rod 15 protruding from the needle 7, and these heads 18 are opposed to the tips of the respective horizontal needles 7, respectively. Each push rod 1
5 is biased rearward by a spring 19 installed therein so that the head 18 is always in contact with the front plate 17;
In this state, the bumper member 2 for contacting the auxiliary opening plate 9 protrudes forward of the head 18 by a predetermined length.
0 are provided protrudingly on both left and right sides of the front plate 17.

The excitation winding 32 wound around the magnetic body 31 of each actuator 13 is connected to a terminal plate 21 provided at the rear of the frame 11, and the terminal plate 21 is connected to the conversion mechanism 10.
It is electrically connected by a cord 23 to another signal output means 22 installed at an appropriate position, such as near the loom, and each actuator 13 operates its excitation winding based on an electric signal command from the output means 22. It is adapted to be activated by individual excitation of the magnetic body 31 by the magnetic body 32.

The signal output means 22 is, for example, a magnetic tape or a floppy disk on which weaving pattern information is magnetically recorded by a computer-based pattern decomposition device as a control signal for selecting desired pushing and non-pushing of each horizontal needle for warp operation. A floppy disk, or a perforated tape or perforated disk on which selection control signals are perforated, is used as the recording means, and the magnetic tape is also used with a magnetic head in the case of a floppy disk, and a phototransistor or laser in the case of a perforated tape or perforated disk. An optical device is used as a reading means, and the excitation winding 3 of each actuator 13 is read from the reading means via a storage device and a power supply device.
2, an electric signal is sent by selecting either the forward or reverse current direction. In this case, the storage device and the power supply device are not limited to being installed on the signal output means 22 side, but can be installed on the conversion mechanism 10 side.

Next, details of an embodiment of the conversion mechanism 10 will be described with reference to FIGS. 2 to 6 and further to FIGS. 7 to 11.

As mentioned above, the front plate 17 is elastically supported by springs 16 at appropriate intervals with respect to the frame 11, and the elastic support springs 16 are installed at a total of four locations, two on the left and right sides of the frame 11, two above and below. (See Figures 2 and 4). The front plate 17 is guided by guide means 24 installed at four locations in the same manner as the elastic springs 16, and the front plate 17 is guided by the frame 1.
1 in such a manner that it can be moved toward the spring 16 against the spring 16 (see FIGS. 2 and 5).
The guide means 24 is configured by slidably inserting a slide pin 27 into a front and rear through hole 26 formed in a guide member 25 biased at the end of the frame 11, and attaching the front end of the pin 27 to the front plate 17 with a bolt or the like. Twist and connect pin 2
A stopper member 28 for the back of the frame 11 is attached to the rear end of the frame 7 with bolts or the like. As a result, the front plate 17 is normally biased by the spring 16 to maintain a predetermined distance in front of the frame 11, and the guide means 24 penetrates against the biasing force of the spring 16. The frame 11 can be approached by sliding guidance of the slide pin 27 along the hole 26.

In addition, brackets 29 are attached to the left and right sides of the frame 11, and by appropriately attaching attachment members 30a having shafts 30 corresponding to the left and right protruding core shafts of the pattern paper cylinder to the brackets 29, the entire mechanism 10 can be assembled. It is said that it can be easily attached to the part that replaces the pattern paper cylinder of the jia card machine (see Figures 2 and 3).

The head 18 of each push rod 15 is made of a synthetic resin material and is formed to be thicker than the horizontal needle 7, and the difference in the length of the forward protrusion from the front plate 17 between the head 18 and the bumper member 20, as well as the frame 11 and front plate 17
The distance between the horizontal needle 7 and the horizontal needle 7 is appropriately set depending on the amount of operation to be pushed, and is, for example, about 9 mm.

Each actuator 13 is made of a rod-shaped magnetic material 31 made of iron or other hard material that is easily magnetized.A very thin insulated conductive wire is connected to the outer periphery of the rod-shaped magnetic material 31, except for the tip, through an insulating layer as thin as possible. It is constructed by winding the excitation winding 32 in multiple layers in a tapered shape, and the rear end of the magnetic body 31 is supported by a vertical pivot 33 with respect to the frame 11. The tip of the magnetic body 31 can be rotated left and right around a rear end pivot 33 (see FIGS. 2 and 6). In such movable pivoting of the magnetic body 31 of each actuator 13,
For example, a vertical axis 3 mounted between the top and bottom of the frame 11
3, a flanged ring spacer 40
and bushes 41 are inserted in an alternating order, and each time the boss portion 42 provided at the rear end of the magnetic body 31 is rotatably loosely inserted into the outer periphery of the bush 41 between adjacent spacers 40. Excited (No. 6)
(see Figure 11). In this way, it is possible to easily arrange the magnetic bodies 31 at accurate pitches that follow the pitches of the horizontal needles 7. In this case, frame 1
1, the pivot 33, the spacer 40, the bush 41, etc. are made of non-magnetic material, and preferably the boss portion 42 is also made of non-magnetic material.

As shown in FIG. 7, the permanent magnet structure 14 is arranged such that the magnetic bodies 31 of each actuator and each push rod 15 are arranged between the magnetic bodies 31 and the push rods 15 in the horizontal direction.
1 and the push rod 15, vertically long strip-shaped magnetic pole plates 34 made of a hard and highly magnetized magnetic material are arranged facing each other at equal intervals, with a facing interval of about 2 to 3 times the thickness of the push rod 15. , permanent magnets 35 are sandwiched between the arranged plate bodies 34 at both upper and lower ends. In this case, each permanent magnet 35
is assumed to have an S pole and a N pole on the left and right sides, and the S pole side and the N pole side are alternately reversed one by one in the left and right arrangement order. As a result, each of the magnetic pole plates 34 arranged at intervals on the left and right sides alternately has magnetic poles of different S and N poles. A pair of S and N poles adjacent to each other and facing each other as a partition wall.
Magnetic pole plates 34, 34 having magnetic poles with different polarities
A corresponding space 36 in which the tip of the magnetic body 31 of each actuator is exposed is formed between the opposing magnetic pole surfaces of the permanent magnet structure 14. In addition, in the configuration of this permanent magnet structure 14, as shown in FIGS. 8 to 10, a push rod insertion hole is provided between each magnetic pole plate 34 at a position biased towards one of the magnetic pole plates in each pair on the front side. 37, and on the rear side there is a slit 3 for inserting the magnetic body 31 movably from side to side with a length extending between both magnetic pole plates in each pair.
8, and an intervening member 36 made of a non-magnetic material is preferably inserted so as to form each corresponding space 36 in the form of a shelf. The tip of the magnetic body 31 is inserted through the slit 38, and the rear end of the push rod 15 is inserted through the insertion hole 37 close to and opposite to the tip.

As the magnetic pole plate 34, for example, permalloy, silica steel plate, or the like may be used. Further, as the permanent magnet 35, for example, an alnico-based cobalt magnet or the like may be used. The facing arrangement pitch of each of the magnetic pole plates 34 is set to correspond to the arrangement pitch of the horizontal needles 7 of the Jacquard machine, and under the restriction of this pitch dimension, the thickness of the magnetic body 31 of each actuator 13 and the amount of operation are determined. In view of the favorable conditions such as
The facing distance between adjacent magnetic pole faces of each magnetic polarity 34 is made as large as possible, and therefore the thickness of each magnetic pole plate 34 is made as thin as possible. To give an example of the dimensions, for example, in the case of a Nishijin-type jacquard machine, the arrangement pitch of the horizontal needles 7 is 5.13 mm, so the arrangement pitch of each magnetic polarity 34 is set as such, and each magnetic pole plate 34 has a thickness of 5.13 mm. 1.05mm made by stacking three 0.35mm geisha steel plates
As a result, the distance between the adjacent magnetic pole faces of each magnetic pole plate 34 was 4.08 mm, and the magnetic body 31 of each actuator 13 had a diameter of about 1.6 mm. It will be done like this.

Next, to describe the operation of the above-mentioned device, each actuator 13 individually transmits an electrical signal of textile pattern information from the signal output means 22 to the excitation winding 32 selectively in the forward and reverse direction of the current. This is applied as electricity, whereby the tip of the magnetic body 31 can be selectively excited to either the S pole or the N pole. By such switching excitation of the polarity of the magnetic pole, the tip of the magnetic body 31 is moved in the corresponding space 36 of the permanent magnet structure 14 to the S-pole surface and the N-pole surface of the opposing magnetic pole plates 34, 34 forming the partition wall. This causes an effect of being selectively attracted to one of the pair of magnetic pole faces having different polarities and switching to contact with the other.

This allows the tip of the magnetic body 31 to move into the corresponding space 36.
2 of rotation around the rear end pivot 33 inside.
It is selectively actuated between positions. During the two-position operation, when the tip of the magnetic body 31 is in one position, the tip of the magnetic body 31 is not engaged with the rear end of the push rod 15 because its axis is not aligned and cannot come into contact with it. Conversely, when the tip of the magnetic body 31 is in the other position, the tip is axially aligned and aligned with the rear end of the push rod 15, and is in a state where it can abut and engage. Such two-position operation of the actuator 13 is performed by the excitation winding 3.
2, and can be easily and easily realized by instantaneous pulses. and magnetic material 3
Once 1 is attracted and transferred to the magnetic pole side of one polarity in the permanent magnet structure, even if the electric signal is stopped and it is no longer excited, it will continue to move as long as the next electric signal does not switch to the opposite direction side. , has the effect of remaining attracted to that position.

Therefore, the switching operation between the two positions of each actuator 13 resulting in an electric signal from the signal output means 22 is performed every time the frame 11 moves back and forth, so that each horizontal needle 7 can be selectively pressed. Dynamic control is achieved through the following actions.

That is, now the frame 11 and therefore the conversion mechanism 1
When the entire needle 0 is in the retracted position in its reciprocating motion, the bumper member 20 is separated from the auxiliary opening plate 9, and the head 18 of each push rod 15 projects from the auxiliary opening plate 9. It is in a state away from the tip, and this state is shown in FIG. Next, the frame 11 and therefore the conversion mechanism 10
As the whole moves forward, the bumper member 20 first comes into contact with the auxiliary opening plate 9, as shown in FIG.
The heads 18 of the needles 18 are in close contact with the tips of the corresponding horizontal needles 7, and in or before this state, the selective operation of each of the actuators 13 between the two positions is triggered by the signal output means 22. It is done based on electrical signals. Subsequently, when the frame 11, and therefore the entire conversion mechanism 10, further advances and reaches the maximum forward position, as shown in FIG. The plate 17 is brought into relative proximity to the frame 11 against the force of the spring 16, with each push rod 15 having its magnetic body removed by the selective actuation position between the two positions of each corresponding actuator 13. 13, which come into contact with the tip and those which do not come into contact with it. As a result, each push rod 15
Those whose rear ends do not align with and come into contact with the tip of the magnetic body 31 enter the corresponding space 36 of the permanent magnet structure 14 backwards, misplacing the tip of the magnetic body 31, so that the head 18 does not project forward in any way from the front plate 17 and does not push the corresponding horizontal needle 7 in any way, whereas the one whose rear end aligns and abuts the tip of the magnetic body 31 is pushed by the tip and is pressed by the spring 19. In response, the frame 11, and therefore the entire conversion mechanism 10, is moved forward and its head 18 is projected forward from the front plate 17, pushing the corresponding horizontal needle 7. In this way, in this device, the mechanical reciprocating movement of the conversion mechanism 10 and the two movements of each actuator 13 at that time are achieved.
Selective pushing control of the horizontal needles is achieved by the excitation operation between positions, and based on the weave pattern information, the opening operation of the warp threads of the jacquard machine is performed without using pattern paper, making it possible to weave textiles. . In addition, in its operation, when the frame 11 is in the retracted position during reciprocating movement of the object, it is already in the 12th position from the beginning.
It is also possible for the bumper member 20 to be in contact with the auxiliary opening plate 9 as shown in the figure.

In addition, in the configuration of the permanent magnet structure 14 shown in FIGS. 7 to 10 described above, since each magnetic pole plate 34 is alternately set as an S pole and a N pole in the left and right arrangement, the operation is performed every pitch in the left and right direction. The relationship between the forward and reverse directions of the current to the excitation winding 32 of the child 13 and the engaged and disengaged positions of the push rod 15 must be alternately reversed by a signal command. In order to eliminate this, as shown in FIG.
4, each magnetic pole plate 34 has a structure in which magnetic pole plates 34b and 34c made of a magnetic material are arranged in a layered manner on the front and back surfaces of the plate 34a made of a non-magnetic material. The directions of the S and N poles of each permanent magnet 35 are all the same, and the magnetic pole plates 34b and 34c made of magnetic material on the front and back sides of each magnetic pole plate 34 are set as S and N poles, or, If possible, the permanent magnet 35 may not be used, and the front and back magnetic pole plates 34b, 34c themselves may be made into permanent magnet bodies with S and N poles.

Next, a modification is shown in FIG. 16, in which intermediate members such as the front plate 9 and the push rod 15 employed in the embodiment shown in FIG. 1 are omitted. The tip of each horizontal needle 7 is interlocked and connected so as to be directly related to the magnetic body 31 of each actuator 13, thereby simplifying the structure.

Although not shown, in the present invention, as a further modified example, the switching mechanism 10 employed in the embodiment shown in FIG. Instead of having a It is possible to provide means for elastically pushing each horizontal needle 7 through a spring or the like on the front side.

Next, FIG. 17 shows an embodiment in which this invention device is applied to a paper punching machine. In this figure, the main components of a conventionally known paper perforation machine are indicated by reference numeral 5.
It is comprehensively indicated by 0. The patterned paper punching machine 50 has a machine frame 51, a base plate 52 for punching patterned paper, and a plurality of chisels 5.
3 is included. The base plate 52 has a hole corresponding to each chisel 53, and is moved up and down by a vertical movement means 54 such as a crank mechanism. Each chisel 53 extends vertically on the base plate 52 and is supported so as to be movable up and down. The pattern paper 55 to be perforated is intermittently fed one sheet at a time onto the base plate 52 in synchronization with the vertical movement of the base plate 52, and is fed as needed by each chisel 53 when the base plate 52 moves up and down. perforations are made.

The upper part of each chisel 53 is engaged with a plurality of corresponding horizontal control bars 56. Each control horizontal bar 56 is capable of reciprocating in the lateral direction (lengthwise direction), and in the figure, each right end portion corresponds to a plurality of tube-covered flexible wires or horizontal bars for pushing operation. 57 and is selectively pushed by selective pushing of the wire or crossbar 57. The perforation action of each chisel 53 is selected by the displacement of movement caused by selective pushing of each horizontal bar 56, and perforation is sequentially performed on each sent pattern paper 55 based on the weave pattern information. . Further, the left end side of each horizontal bar 56 in the figure is pushed back to its original position all at once by a reset pushing plate 58 which reciprocates for each drilling operation. In such a pattern punching machine 50, the operating ends of the wires or horizontal bars 57 as input members for controlling the pattern punching are opposed to each other, and each actuator 13 is connected to the operating end thereof. A mechanically reciprocated converting mechanism 10 similar to that of the Jacquard machine of FIG. 1 is arranged.

However, in this lever device, the perforation of the pattern paper used in the conventional jia card machine can be made by the electric signal of the weave pattern information from the signal output means 22.

In the device described above as an embodiment, as described above, the tip of the magnetic body 31 of each actuator 13 is selectively switched and excited between the S pole and the N pole, and the pair of magnetic pole plates 34, When the magnetic body 31 is selectively attracted to the north and south pole faces of the magnetic body 34 and moved between two positions, the tip of the magnetic body 31 as the attracted part is attracted to the magnetic pole plate 34,
If the N-pole surface and the S-pole surface of the excitation winding 32 are to be in direct contact with each other, the power for energizing the excitation winding 32 for its operation may be small in that it can be driven in pulses, but it will require a certain amount of power. In addition, the permissible range of power fluctuations to ensure reliable operation is narrow, and malfunctions may occur in some cases. That is, for example, if the tip of the magnetic body 31 is now excited as an S pole and is attracted to the N-pole side of the magnetic pole plate 34 and comes into direct contact with it, the magnetic body and the magnetic body on the N-pole side will directly contact each other. The contact can produce an effect that forms a local magnet in that part, such as creating an integral magnetic field, and for this reason, the other S
The magnetism of the magnetic pole plate on the pole side is relatively weakened,
In this way, the magnetic flux densities of the magnetic pole plates 34, 34, which form a pair of N-pole and S-pole surfaces, become relatively unequal, causing a change in magnetic balance. Therefore, when the tip of the magnetic body 31 is next excited as a north pole from that state and is attracted to the south pole side of the opposite magnetic pole plate, the strength of the magnetic force is 2 times the distance. Combined with being inversely proportional to the power of
For this reason, it is difficult for the magnetic pole plates that were originally in contact to separate from the N-pole surface, and it is necessary to increase the power to the excitation winding considerably, and if the power is increased too much, the magnetic pole plates that were originally in contact will tend to make more firm contact. This may even make it difficult to perform the disengagement operation. Moreover, especially when one magnetic pole plate 34 forms a common attracting magnetic pole surface member for the magnetic bodies 31 of a large number of vertically arranged actuators, as in the permanent magnet structure 14 of the embodiment, The influence of the above-mentioned effects is increased, so that in some designs, for example, one pole plate 34
There may be cases where a large number of actuators 13 are attracted in the same way to the magnetic pole surface of the magnetic pole surface, resulting in uneven operating positions. There is a high risk of malfunction due to lack of accuracy in operation, such as the inability to operate the device in the crooked position.

Therefore, in this invention, FIGS. 14A to 14D
As shown in the embodiment, the magnetic body 31 in each actuator 13 is attracted to the N-pole surface and the S-pole surface of the magnetic pole plate.
The adsorbed part, that is, the tip part 31a here,
It is coated with a coating material 45 made of a non-magnetic material, so that when the magnetic material 31 is attracted to either the N pole face or the S pole face of the magnetic pole plate, the magnetic material 31 is not attached to those pole faces. The gist of the present invention is that the contact is made through the covering material 45 made of a non-magnetic material without direct contact.

However, by doing so, there is no fear of forming the local magnet mentioned above,
This makes it possible to maintain as uniform a magnetic flux surface as possible on the magnetic pole surface of each magnetic pole plate 34, and also prevents the interposition of the coating material 45 made of a non-magnetic material on the magnetic pole surface of the magnetic pole plate 34 during adsorption. Therefore, the distance between the tip 31a, which is the attracted part of the magnetic body 31, is maintained, and the operation between the two positions of the actuator 13 can be performed accurately with small electric power and with less risk of malfunction. The allowable range of power fluctuations to ensure this will also become wider.

That is, the tip 31a of the magnetic body 31 during operation
When is coated with a non-magnetic material, the strength of magnetization of the magnetic material 31 when it is attracted to the magnetic pole plate 34 decreases by an amount approximately proportional to the square of the thickness of the coating material.
This is because when driven in the opposite direction from that state, less power is required to cancel the magnetization of the magnetic body 31, and the mechanical shock when it collides with the opposite pole is correspondingly reduced.

In addition, the coating material 45 made of a non-magnetic material is attached to the magnetic material 31.
If the same effect is obtained by providing the covering material 45 on the magnetic pole surface side of the magnetic pole plate 34 instead of providing it in this way, the arrangement pitch of the magnetic pole plate 34 as described above may be changed. However, it has the advantage that it can be carried out regardless of such constraints, and the advantage that it protects the magnetic body 31 from damage and increases durability.

In this case, it is preferable that the coating material 45 is cylindrical or cap-shaped as shown in the figure, and is coated on the tip 31a of the magnetic body 31, and its cross-sectional shape is the S of the magnetic pole plate. The magnetic material 3 is made to have the same thickness on the left and right sides toward the pole face and the north pole face, and may be made into a circular shape, a square shape, or other suitable shape.
1 is generally circular in cross section. And if it is cylindrical,
The distal end of the tip 31a of the magnetic body 31 may protrude somewhat from the sheathing material 45, but preferably the sheathing material 45 is aligned with the distal end 31a at the distal end surface or protrudes somewhat on the distal side. In this way, the tip of the magnetic body 31 is engaged with the push rod 15, the horizontal needle 7, the wire or the horizontal bar 57 through the covering material 45, and damage is prevented. This increases durability.

Further, in this case, the tip 31a of the magnetic material 31 may be covered with the coating material 45 without being made thin as in the embodiment shown in FIG. In some cases, it may be difficult to implement this method due to restrictions on the thickness of the coating material 31 or the thickness of the covering material 45, or it may not be possible to expect the desired good effect. Therefore, as in the embodiments shown in FIGS. 14B to 14D, the tip 31a of the magnetic body 31 is formed to be thinner than the other portions, and the thinner tip 31a is covered with the coating material 45. It is very preferable to do this, and in this way, the thickness of the covering material 45 can be made as thick as possible without being subject to dimensional restrictions, and only the tip part 31a of the magnetic material is made thin, and the other parts are made as thin as possible. Since it can be made thicker, the efficiency of the excitation action of the tip portion 31a by electric power can be increased. In addition to the above-mentioned general reason that the magnetization strength decreases during adsorption due to the thickness of the covering material, this allows the actuator to operate without malfunction even with a small electric power. That is, as the tip portion 31a of the magnetic body 31 becomes thinner, the magnetic flux density increases when the magnetic body 31 is excited and magnetized with the same amount of energy. It is possible to reduce the power consumption for generating. In this case, it is more advantageous to make the tapered tip 31a further tapered or tapered as in the embodiment shown in FIG. 14D.

As the covering material 45, metal or other suitable material such as stainless steel or ceramic may be used, but it is preferable that the material is as non-magnetic as possible, hard and durable, and preferably non-conductive. This is advantageous because the insulation between the magnetic material 31 and the magnetic pole plate 34 is maintained, and in this respect, ceramic, which is a hard, non-conductive, non-magnetic material, is most suitable as a current material.

An example of the dimensions of the covering material 45, etc. is shown in the example of FIG. 14B or FIG. Assuming that the total length is approximately 40 mm, the diameter and length of the tip 31a are 0.5 mm.
mm and 4 mm, and the outer diameter is 2 mm for this tip 31a.
For example, a covering material 45 made of a cap-shaped or cylindrical magnetic material having a length of about 7 mm and a length of about 7 mm is coated.

Therefore, the results were obtained by comparing the operation of the one in FIG. 14B or FIG. 14D covered with a covering material 45 of such dimensions and the one without any covering material 45 of similar dimensions. According to the inventor's experiments, the latter was operated with a power of about 500 mmA, and if the fluctuation of the power exceeded about ±10%, it stopped working or caused serious malfunctions. The former device can operate at approximately 50 mmA, and it has been found that it operates extremely accurately and smoothly without malfunction within a fluctuation range of approximately ±30% of that power.

As is clear from the above description, according to the present invention, the mechanism for converting an electrical signal into a mechanical operation is
It has a magnetic material and an excitation winding wound around it.
It is simply constructed with elements of an actuator that is movable between positions, and a permanent magnet structure that has a pair of north and south pole faces that are placed at fixed positions, and therefore the structure is simplified. Miniaturization is possible, and the entire device can be manufactured compactly and relatively inexpensively. Moreover, the operation is such that the magnetic body is selectively switched and excited by energizing the excitation winding with an electric signal based on the weave pattern information of either forward or reverse direction.
Since it is selectively switched and adsorbed to either the pole surface or the S pole surface, it can be operated by pulse drive, and the operation is smooth and reliable, with high responsiveness, and high-speed operation is possible without problems. It is possible to operate with small electric power.

In particular, the attracted part of the magnetic material in each actuator that is attracted to the N-pole surface and the S-pole surface of the permanent magnet structure is coated with a coating material made of a non-magnetic material. When the magnetic material is attracted to either the surface or the south pole surface, the magnetic material does not come into direct contact with the polar surface, but comes into contact with it through a coating made of non-magnetic material. Smooth and accurate operation can be obtained with low power consumption and no risk of malfunction.
