In the figure, the main components of a conventionally well-known Jacquard machine are collectively indicated by the symbol (1), the mechanical part that converts electrical signals into mechanical operations is collectively indicated by the symbol 00), and the weave pattern information is The signal output means for extracting the signal as an electrical signal is designated by the symbol (2).
2).

The Jacquard machine (1) has a plurality of vertical needles arranged and supported on a bottom plate (6), which can be moved up and down by hooking their upper end hooks to knives (3) of a vertically moving knife box (2). At the bottom of the needle there is a code (

Therefore, the conversion mechanism 00 is disposed in place of the paper cylinder at the position where the paper cylinder should originally be installed.

The conversion mechanism (lO) includes a box-shaped mechanism frame at+ approximately the same size as the original paper cylinder.

The frame 01) is horizontally moved by a bara tan (12) as shown in the figure, which is driven by a rod drive, shaft drive, chain drive, etc. from the crankshaft of the loom, etc., as well as the original pattern paper cylinder, or other suitable driving means. needle(
The reciprocating movement in the longitudinal direction of the horizontal needle (7), which is used to push and move the force, is performed mechanically.

Inside the frame 0υ, there are a plurality of horizontal needles each equipped with a permanent magnet (c31) so as to correspond to one of the horizontal needles (7) at a pitch equal to the pitch according to the force arrangement. A light-acting actuator α9 is arranged and arranged opposite to each horizontal needle (force).The tip of each actuator a is equipped with a plurality of solenoid structures arranged at fixed positions corresponding to the arrangement. 04)
Two stepwise branched portions (32a) at the tip of the magnetic rod (32).

(32b). And each actuator (Q
The tips of 3) are closely opposed to the rear ends of the lateral needles (the bushing rods 05 that mediate the pushing and moving of force) arranged further forward in accordance with their arrangement. Each bushing rod a9 is inserted through the front plate α force, which is elastically supported at an appropriate interval so as to be accessible by a spring (16), so as to vibrate freely at the front part of the frame Uυ.

A slightly thickened cap-shaped head 08) is formed at the tip of each bushing rod 09 protruding from the front plate αD, and each of these head barrels is opposed to the corresponding horizontal needle (force tip). .Each bushing rod (15) always has its head 08) fixed to the front plate 07 by a spring Q91 installed therein.
), and in this state, the auxiliary opening plate (9) protrudes forward by a predetermined length from the head 0ne.
A member Cα for contacting the front plate α is provided protrudingly on both the left and right sides of the front plate α force.

An excitation winding (33) is wound around the magnetic rods (three of each solenoid structure Q4), and the excitation winding (33) is
Each of them is connected to a distribution board (34) through a terminal plate Cυ provided at the rear of the frame enclosure, and the distribution board (34) is connected to the conversion mechanism 0.
0) is electrically connected to a signal output means (22) installed at an appropriate position, such as near the loom, by a cord (23), and each solenoid is The magnetic rods (321) of the structure Q4) are individually excited by the excitation winding C33), and each actuator 03 is individually actuated by this excitation.

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 disk, or a perforated tape or perforated disk on which selection control signals are perforated and recorded, is used as a recording means, and in the case of a magnetic tape or floppy disk, a magnetic head is used, and in the case of a perforated tape or perforated disk, a phototransistor or a laser beam device is used. A device that is used as a reading means and sends an electric signal from the reading means to the excitation winding (c) of each solenoid structure Q4) by selecting either the forward or reverse current direction via the storage device and the drive circuit device. It is said that In this case, the storage device and drive circuit device are the signal output means CI! It is possible not only to equip it on the z side but also on the conversion mechanism 00) 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 9.

As mentioned above, the front plate dη has a spring (16
), and the elastic support springs f161 are installed at a total of four locations, two on the left and right of the frame Ql), two on the top and bottom (see FIGS. 2 and 4). The front plate aη has guide means 0 installed at four locations similar to the elastic spring Q6).
4) and is supported so that it can be moved toward the frame 01) against the spring ae (second
(See Figure 5). The slide pin (27) is slidably inserted into the front and rear through holes (A) drilled in the guide member (251) which is biased at the end of the guide means (24J is the frame Ql).
Fixedly connect the front end of the pin frame to the front plate surface with bolts etc.
The stopper member side for the back of the frame Ql) is attached to the rear end of the pin (2?) with a bolt or the like. As a result, the front plate 07) is normally in a position where it is biased by the spring 0e and maintains a predetermined distance in front of the frame Uυ, and
The through hole (
26) and can approach the frame Uυ by sliding guidance of the slide pin (27+).

In addition, a platen (29) is attached to both the left and right sides of the frame αυ, and an axotiment member (30a) having a shaft (30) corresponding to the left and right protruding core shafts of the patterned paper cylinder is attached to this platen (29) as appropriate. By attaching it, the entire mechanism 00) can be easily attached to a part of the Jacquard machine that replaces the pattern cylinder (Fig. 2,
(See Figure 3).

The head side of each bushing rod Q51 is made of something like a synthetic resin material, and the cross needle (force and width is also thick), and the front plate (IT) between the head α mallet and the bumper member ■ is connected forward. The protrusion difference length and the distance between the frame (11) and the front plate surface are appropriately set according to the amount of operation to be pushed by the horizontal needle (7),
For example, it is about 9n.

Each solenoid structure 04) is made of a magnetic rod (33) made of a highly magnetic material such as permalloy, whose tip is branched into steps, and two branched parts (32a) and (32b) are arranged in a plate shape at predetermined intervals. The excitation winding is formed by winding a pole (thin insulated conductive wire multiple times) with an insulating layer as thin as possible on the outer periphery of the rod c32, excluding the branched tip. C(3) (see Figures 7 and 8). Each solenoid structure Q4) connects the rear end of the rod (321) to the rear of the frame aυ and connects it to the internal terminal plate Cυ. At the same time, the tips of the two branched parts (32a) and (32b) at the tip of the rod C33 are inserted into the inner support plate (13) on the front side of the frame [1].
(g) and is fixed by being fitted and supported. As a result, each solenoid structure α is spaced apart from each other so that the horizontal needles (force arrangement) are spaced apart from each other.

They are very easily arranged in a stationary manner with a pitch that exactly corresponds to the pitch, and their mutual spacing eliminates the interfering effects of their excitations on each other. The terminal plate (2η) and the support plate C39 are preferably made of non-magnetic material such as Bakelite, glass epoxy, or stainless steel, and more preferably the frame (11)
It is also assumed that the material is made of non-magnetic material. The terminal board (2I) is
It can itself be a printed wiring board, and in this way, the circuit connection of the conductive wire of the excitation winding (33) is very easy.

As shown in FIG. 9, each actuator Q31 is shaped like a plate and is movably installed in the center between the two branch parts (32a) and (32b) of the corresponding solenoid structure 0□0. Ru. This installation has two branches (32a).

(32b), install the support shaft □□□ between the top and bottom of the frame (old), and attach the support shaft (38) to the actuator 0 (
This is achieved by pivoting the rear end of the actuator 0□
□□ is rotatable around the support shaft (G), and one side of the tip touches the inner surface of one branch (32a) and the other side of the tip touches the inner surface of the other branch (32b). It is designed to be able to occupy two positions.

Note that the support shaft side is preferably made of a non-magnetic material.

Each actuator (131) is preferably made of a non-magnetic material, very preferably made of ceramic, which is a non-magnetic material with high hardness, and a permanent magnet C31+
will be equipped. The permanent magnet (31) is made of Sli on one side facing the inner surface of one branch part (32a) of both sides of the actuator α, and Nli on one side facing the inner surface of the other branch part (32b). (See Figure 7). This equipment is made, for example, as shown in the figure, by inserting and fixing a permanent magnet t31 into a hole drilled near the tip of the actuator so as to penetrate on both sides. In the illustrated example, the permanent magnet c31) is disk-shaped with one side as the N pole side and the other side as the S pole side.
(It is equipped to be displayed on both sides of 131,
This may be square, or may be embedded inside the actuator (131) so as not to be exposed.

As the permanent magnet (31), for example, an alnico-based cobalt magnet or the like may be used.

The support plate C35) has a hole at a position corresponding to the tip of the actuator (+3) when one side of the tip of the actuator (131) is in contact with the inner surface of one branch (32a). (39 is drilled, and the rear end of the corresponding bushing rod (1'5) is slidably inserted into this hole (39).
(See Figures 7 and 8). As a result, when one side of the tip of the actuator (131) occupies a position in contact with the inner surface of one of the branch parts (32a), the bush rod (one rear end is closely opposed to the tip of the actuator αJ, and in this state Sometimes, the rear end of the bushing rod (151) comes into contact with the tip of the actuator OJ and is obstructed so that it cannot enter between the two branch parts (32a) and (32b) any more, but the tip of the actuator (13) When one side is in contact with the inner surface of the other branch (32a), the tip of actuator 03) is retracted from the rear end of bushing rod (15), and the rear end of bushing rod 0■ is in contact with actuator 031. It is assumed that the two branches (32a) and (32b) can be inserted in between the two branches (32a) and (32b).
), (32b) are set to a dimension that makes the above possible in relation to the thickness of the actuator α (g) and the thickness of the book rod (15), but at least the thickness of the book rod (15) It is set to a little more than twice that of .

Note that there are two branch parts (32) where the tip of the actuator (13) touches.
The inner surfaces of a) and (32b) are coated with a very hard non-magnetic material layer (10) such as ceramic.
This is highly preferred in terms of durability and smooth operation.

Next, to describe the operation of the above-mentioned device, the signal output means (2
The electrical signals of the textile pattern information from 2) are individually given as selective energization in the forward and reverse directions of current.

As a result, the two branch parts (32a) and (32b) at the tip of the magnetic rod (32) of each solenoid structure Q4)
Both magnets are selectively switched to either the N pole or the S pole.

When the two branch parts (32a) and (32b) are excited as Nli, the actuator αJ between them is such that one side of the S pole side of the equipped permanent magnet C31) is connected to the corresponding branch part. (32a), so that its tip occupies a position where it comes into contact with the inner surface of one of the branch parts (32a). On the contrary, two branch parts (32a), (3
2b) is excited as an S pole, the other side of the NFM side of the equipped permanent magnet (31) is attracted to the corresponding other branch part (32b), so that its tip is attracted to the other branch part (32b). (32b) will occupy a position in contact with the inner surface.

In this way, each actuator OJ has two corresponding branch parts (
32a) and (32b), with the tip rotating around the rear support shaft (to) and occupying a position where the tip abuts the inner surface of one branch part (32a) and the other branch part (32b). The position can be selectively changed between the abutting position and the two positions. As mentioned above, in one position, the tip of actuator 0 (to) can come into contact with the rear end of bushing rod 09, and in the other position, the tip of actuator (13) is in contact with the rear end of bushing rod 09. It becomes impossible to abut and engage with the rear end of. Such two-position operation of the actuator 03) requires a small power load on the excitation winding (33).
Moreover, it can be realized lightly, smoothly, and precisely by means of instantaneous pulses. When the actuator 03) moves to a position where it is attracted to one of the two branches (32a) and (32b) depending on the polarity of the permanent magnet C31), the electric signal is stopped and the two branches (32a), (3
Even if 2b) is no longer excited, it remains attracted to that position unless it is switched to the next opposite direction by an electric signal.

Therefore, the switching operation between the two positions of each actuator 0 by the electric signal in the forward and reverse directions of the current from the signal output means (2 sudden) to the excitation winding (331) of each solenoid structure K (14) is as follows. By performing each reciprocating movement of the frame Uυ, selective push control of each meter reading (7) is achieved by the following action.

That is, when the frame aD, and therefore the entire conversion mechanism (10), is in the retracted position during its reciprocating movement, the bumper member (2υ) is separated from the auxiliary opening plate (9), and each bushing rod (15) is Each corresponding transverse needle whose head group projects from the auxiliary mouth plate (9) is located away from the tip of the force, and this condition is shown in FIG. 2. Next, the frame (11) However, when the entire conversion mechanism (10) advances by mJ, the bumper member (20) first comes into contact with the auxiliary opening plate (9), as shown in FIG. , each bushing rod (head 08 of 151) is in close proximity to the state in which it is almost in contact with the tip of each corresponding horizontal needle (force), and in this state or before, each of the above-mentioned actuators (13)
The selective operation between the two positions is performed based on the electrical signal from the signal output means (22).Subsequently, when the frame 01) and therefore the entire conversion mechanism QQ) further advances to the maximum forward position, As shown in FIG. 11, due to the bumper member (2) coming into contact with the auxiliary opening plate (9), the front plate 01 is moved relatively close to the frame 0υ against the spring 06, At this time, each bush rod (15
), depending on the selective operating position between the two positions of each corresponding actuator (13), one is brought into contact with its tip and the other is not brought into contact. As a result, each bushing rod 05), of which the rear end does not come into contact with the tip of the actuator (13), has two branch parts (32a),
(32b) and enters backwards, misplacing the tip of actuator 0 While it does not move in any way, the rear end of the actuator 03) is pushed by the tip of the actuator 03) and is pushed against the spring (1gI by the frame aD).
Therefore, as the entire conversion mechanism 00) moves forward, it is moved forward and projected forward from its head (front plate C17), pushing the corresponding meter reading (7). In this way, in this device, selective push control of the horizontal needles is achieved by the mechanical reciprocating movement of the conversion mechanism 00) and the selective operation of each actuator 03 between two positions by the electrical signals at that time, and the weave pattern is Based on this information, the shedding operation of the warp threads of the jacquard machine can be performed without the use of pattern paper, and the fabric can be woven.

In this operation, when the frame (11) is in the retracted position during its reciprocating movement, the bumper member (20) is already in contact with the auxiliary opening plate (9) as shown in FIG. 10 from the beginning. It is also possible that they are in contact with each other.

Next, FIG. 12 shows a modified example, in which the front plate (9) employed in the embodiment shown in FIG.
) and the bushing rod α9 are omitted, and the tips of each horizontal needle (7) are interlocked and connected directly to each actuator 03), thereby simplifying the structure.

Although not shown, in this invention, as a further modified example, the switching mechanism 0α employed in the embodiment shown in FIG.
The conversion mechanism 00) is fixed to the rear side of the Jacquard machine (1) so that each actuator 03) is related to the rear end side of each horizontal needle (force) without causing any pushing movement. It is also possible to install a means for elastically pushing each horizontal needle (forced through a spring or the like) on the front side of the Jacquard machine (1).

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 collectively indicated by the symbol (5). A chisel 53) is provided.Base board I
! The i21 has a hole corresponding to each chisel, and is moved up and down by a vertical movement means 54 such as a crank mechanism. Each chisel mark extends vertically on the base plate 5 and is supported so as to be movable up and down. The chisel to be perforated is intermittently fed one by one onto the base plate (52) in synchronization with the vertical movement of the base plate 62, and as the base plate 521 moves up and down, each chisel C' +
31 makes the necessary perforations.

The -E portion of each chisel 53) is engaged with a plurality of corresponding horizontal control bars (A). Each control horizontal bar 6Q 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. 6η and is selectively pushed by selective pushing of the wire or crossbar 6η. The perforation action of each chisel 153) is selected by the displacement of movement caused by selective pushing of each horizontal bar (G), and perforation is performed sequentially for each patterned paper 65) to be fed based on the weave pattern information. It will be done. In addition, the left end side of each horizontal bar (56) in the figure is pushed and returned to its original position all at once by a reset push plate (2) which reciprocates for each drilling operation. In such a pattern paper perforation machine (50), each actuator (one of which is connected in an interlocking state) is arranged to face the operating end of each wire or horizontal bar 6η as an input member for controlling paper perforation. A mechanically reciprocated switching mechanism 00) similar to that of the Jacquard machine of FIG. 1 is arranged in a corresponding manner.

However, with this lever device, the perforation of the pattern paper used in the conventional jacquard machine can be made by electrical signals of the weave pattern information from the signal output means (2).

As is clear from the above description, according to the present invention, the mechanism for converting an electrical signal into a mechanical operation is a mechanism that converts an electric signal into a mechanical operation by connecting a magnetic rod with a (J' It simply consists of a solenoid structure with an excitation winding wound around a rod and an actuator equipped with a permanent magnet movably installed between its two branches, thus simplifying the structure. The entire device can be manufactured compactly and at a relatively low cost.Furthermore, its operation is performed by energizing the magnetic rod by energizing the excitation winding with an electrical signal based on the weave pattern information, either in the forward or reverse direction. The switching excitation of the two branch parts of the tip part is made to have the same polarity, and the installed actuator is attracted to either branch part and moved between two positions depending on the magnetic pole direction of the permanent magnet equipped therebetween. Therefore, the operation is smooth and reliable, the responsiveness is high, high-speed operation is possible without any problem, and the operation can be performed with small electric power.

In particular, the device of this invention can be constructed by arranging one solenoid structure and one actuator individually and independently, so that the interference effect of dark excitation can be eliminated and accurate operation can be expected. In addition, it is very easy to arrange them at an accurate pitch that corresponds to the arrangement pitch of input members such as horizontal needles of the Jacquard machine to which they are applied.
It has the advantage of being very easy to manufacture.
