Description

[Detailed description of the invention] (Industrial application field) This invention is applied to pattern paper operations or similar operations, and is used to move between two positions between a pair of pole plates of a permanent magnet structure by exciting a solenoid. This invention relates to a solenoid actuator that performs a switching operation.

(Prior Art) Conventionally, pattern analyzers have been developed for processing textile pattern information related to the manipulation of warp threads into signals by computers during textile paper manufacturing, and have already reached the stage of practical use. Also,
Attempts have also been made to directly control the operation of a jig guard machine or the like by supplying such signalized weave pattern information as an electrical signal to a jig guard machine or the like. At this time, the device that translates the weave pattern information given as an electrical signal into mechanical motion includes a solenoid actuator that is activated by the electrical excitation of the solenoid as an element of the mechanism that converts the electrical signal into mechanical motion. , which is generally used, and previous attempts have mainly been made using such a method. In that case, the solenoid actuator A, as shown in the sixth figure,
Its tip is covered with a cap-shaped covering material B. As a result, the contact of the permanent magnet structure D with the polar plate E based on the excitation of the tip of the magnetic body C is performed via the covering material B, and the magnetic body C
This prevents damage caused by the tip of the push rod F coming into contact with the rear end of the push rod F.

(Problem to be solved by the invention) However, in the above-mentioned product, the coating material B
is in line contact over a relatively long distance with either the S or N pole of the polar plates E on its outer peripheral surface. Therefore, when oil enters from the push rod F side along the polar plate E,
The amount of oil interposed between the coating material B and the polar plate E increases, and the degree of adhesion between the coating material B and the polar plate C increases due to the viscosity of the oil. may become difficult to separate from the polar plate C. As a result, the smooth operation of the solenoid actuator A was disturbed, and there was a risk that the solenoid actuator A would not operate accurately in accordance with the weave pattern information.

This invention was made in view of the above points, and its purpose is to improve the structure of the cap provided at the tip of the solenoid actuator to make the operation of the solenoid actuator smoother. It's about making sure.

(Means for Solving the Problem) In order to achieve the above object, the solution of this invention consists of a lever body made of a magnetic material whose one end is supported by a pivot, and a solenoid fitted into the lever body. and a cap made of synthetic resin arranged at the tip of the lever body, and the lever body is attracted to one of the pair of pole plates of the permanent magnet structure based on the texture pattern information. At the time, the solenoid actuator is provided which performs a switching operation between two positions by rotating the lever body about the pivot shaft by the excitation effect on the solenoid so that the cap and the pole plate come into contact with each other. The cap is provided with a protrusion extending toward the side where it comes into contact with the electrode plate, and the protrusion comes into contact with the electrode plate.

(Function) With the above configuration, in this invention, based on the electric signal which is the predetermined weave pattern information, the solenoid actuator receives the electric signal of the weave pattern information for the solenoid to select the forward or reverse direction of the current. As a result, the tip of the magnetic body is selectively switched to either the S pole or the N pole and is excited. Due to this switching excitation of the magnetism of the magnetic poles, the solenoid actuator is attracted to one pole of the permanent magnet structure cooperating with the lever body, that is, a pole different from the pole energized at the tip of the lever body. It will come into contact with the polar plate.

At this time, the solenoid actuator contacts one of the polar plates of the permanent magnet structure with the protrusion of its cap, so the contact area becomes relatively small and approaches a point contact state, causing oil leakage. The influence of the viscosity of oil etc. is reduced.

(Example) Hereinafter, an example of this invention will be described in detail based on the drawings.

Referring to FIG. 1, the configuration of a preferred embodiment in which the solenoid actuator according to the present invention is applied to a Jiya Guard machine is shown in which the main components of the Jiya Guard machine are collectively indicated by reference numeral 1, which converts electrical signals into mechanical operations. The mechanical parts for this purpose are collectively indicated by the reference numeral 10, and further, the signal output means for extracting the weave pattern information as an electrical signal is indicated by the reference numeral 22.

The jiya guard machine 1 has a plurality of vertical needles arranged and supported on a bottom plate 6, which can be moved up and down when the upper end hook is appropriately hooked to the knife 3 of a vertically movable knife box 2, and an opening for warp threads is provided at the bottom of each vertical needle. A cord 5 connected to the heald that controls the operation 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. Therefore, each weft needle 7 serves as a heald operating mechanism and constitutes a mechanical transmission means for warp thread operating information.

The conversion mechanism 10 is configured such that at the tip of each horizontal needle 7 immediately in front of the auxiliary opening plate 9 at the front of the Jiya Guard machine 1,
It is arranged at a position facing each horizontal needle 7. Therefore, the conversion mechanism 10 is driven by a button 12 as shown in the figure or other suitable driving means, which is driven from the crankshaft of a loom by a method such as a rod drive, shaft drive, or chain drive, in the same way as a patterned paper cylinder. The reciprocating motion of the horizontal needle 7 in the length direction for pushing the horizontal needle 7 is made mechanically.

At the rear of the inside of the frame 11, there are lever bodies each made of a magnetic material, and lever bodies each made of a magnetic material 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 solenoid actuators 13 each having a solenoid for selectively exciting the main body by an electric signal are arranged and arranged opposite to each horizontal needle 7. The tip of each solenoid actuator 13 has a permanent magnet structure 1 formed in a shelf shape corresponding to the arrangement thereof and arranged at a fixed position.
It is located in each of the 4 spots. The tip of each solenoid actuator 13 is closely opposed to the rear end of each push rod 15 that mediates the pushing motion of each horizontal needle 7 arranged further forward in accordance with the arrangement thereof. Each push rod 15
The push rod 15 is slidably inserted through a front plate 17 which is elastically supported at an appropriate interval so that it can be accessed by a spring 16 at the front of the frame 11. The head 18 is always urged backward in a state in which it is in contact with the front plate 17, and in this state, the bumper member 20 for contacting the auxiliary opening plate 9, which protrudes a predetermined length ahead of the head 18, is pushed forward. They are provided protrudingly on both left and right sides of the plate 17.

Further, the permanent magnet structure 14 is arranged between the lever body 31 of each solenoid actuator and each push rod 15 in the left-right direction.
It is constructed by arranging plate bodies 34 made of longitudinally long strip-shaped magnetic material at equal intervals and facing each other at about three times the interval, and placing permanent magnets 35 at both upper and lower ends between each of the arranged plate bodies 34. Ru. In this case, each permanent magnet 35 to be assembled has an S pole side and an N pole side 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 plate shapes 34 arranged at intervals on the left and right,
Each of the plates 34 has magnetic poles with different polarities of S and N poles alternately, and each plate 34 having magnetic poles with alternately different polarities is used as a partition wall, and each of the plates has a pair of adjacent and opposing polarities. The tip of the lever body 31 of each solenoid actuator is exposed between the plates 34, 34 having different magnetic poles.

Furthermore, each solenoid actuator 13 has a second
As shown in the figure and FIG. 3, a solenoid 32 is attached to a lever body 31 made of iron or other rod-shaped magnetic material.
The lever body 31 is wound multiple times in a tapered shape, and the rear end of the lever body 31 is pivoted to the frame 11 by a vertical pivot 33.
1 is rotatable left and right around a rear end pivot 33. Further, each of the solenoids 32 is connected to a terminal plate 21 provided at the rear of the frame 11.
is electrically connected by a cord 23 to a signal output means 22 installed at an appropriate position, such as near the loom, apart from the conversion mechanism 10, and each solenoid is activated based on an electric signal command from the output means 22. Child 13
are actuated by individual excitation of the lever body by the solenoid 32.

Furthermore, the lever body 3 of the solenoid actuator 13
A cap 45 made of a non-magnetic material such as plastic is provided at the tip of the cap 1 . This cap 45 is formed into a substantially cylindrical shape, and a protrusion 46 is provided at the rear end position. Furthermore, as shown in FIG. 4, this protrusion 46 is formed in a rectangular shape, and both ends of the protrusion 46 protrude in a direction perpendicular to the side that contacts each plate 34, that is, the surface of the plate 34. The plate body 3 extends as shown in FIG.
4. In addition, the protrusion 4
As shown in FIG.
3 may be formed to protrude perpendicularly to the surface of the plate 34 so as to reduce the contact area with the plate 34 when the plate 34 comes into contact with the plate 34.

Next, the operation of the above embodiment will be explained.

The switching operation between the two positions of each solenoid actuator 13 is performed every time the frame 11 moves back and forth based on an electric signal from the signal output means 22.

The reciprocating movement of the frame 11, that is, the selective pushing control of each horizontal needle 7 is performed as follows. When the entire conversion mechanism 10, that is, the frame 11 is in the retracted position during its reciprocating movement, the bumper member 20 is moved toward the auxiliary opening plate 9.
The head 1 of each push rod 15
8 protrudes from the auxiliary opening plate 9, and each corresponding horizontal needle 7
is located away from the tip of the Next, when the frame 11 moves forward, the bumper member 20 first moves to the auxiliary opening plate 9.
In this state, the head 18 of each push rod 15 comes close to almost contacting the tip of each corresponding horizontal needle 7, and in this state or before, the solenoid actuator 13 (described later) Selective actuation between the two positions is based on electrical signals from signal output means 22. Subsequently, when the frame 11 advances further and reaches the maximum forward position, the front plate 17 moves relatively close to the frame 11 against the spring 16 due to the abutment of the bumper member 20 against the auxiliary opening plate 9. At this time, some of the push rods 15 come into contact with the tips of the corresponding solenoid actuators 13, while others do not come into contact with them. As a result, the push rods 15 whose rear ends do not align with and come into contact with the tip of the lever body 31 are misplaced with the tip of the lever body 31 in the permanent magnet structure 14 and are moved rearward. As it enters, its head 18 is the front plate 1.
7 and pushes the corresponding horizontal needle 7.

On the other hand, the switching operation between the two positions of the solenoid actuator 13 is performed by rotating the solenoid actuator 13 around the pivot shaft 33 in each spot of the permanent magnet structure 14 in response to the reciprocating movement of the frame 11. achieved. That is, in its two-position operation,
When the tip of the lever body 31 is in one position, the tip is not axially aligned with the rear end of the push rod 15 and cannot contact and engage with the rear end of the push rod 15; When the tip of the is in the other position, the tip of the push rod
5 and is aligned with the rear end of the shaft 5, and is in a state where it can abut and engage. At this time, a cap 45 is provided at the tip of the lever body 31, and at the rear end of the cap 45, both ends of the protrusion 46 are in contact with the plate 34, that is, the side of the protrusion 46 is in contact with the plate 34. Since it protrudes perpendicularly to the surface, the lever body 31
comes into contact with the plate body 34 only at one end of the protrusion 46, and the contact area becomes extremely small. Therefore, the amount of oil present in the contact area between the lever body 31 and the plate body 34 is reduced, and the switching operation of the solenoid actuator 13 is not hindered due to oil leakage, and the weave pattern information is not transmitted to the machine. can accurately translate the movements of others.

(Effect of the invention) As described above, according to this invention, the solenoid actuator causes the lever body to be attracted to one pole plate of the permanent magnet based on the weave pattern information based on the electric signal from the output means. Selective actuation of two locations, one located at the top of the plate and one remote from the plate, is performed, thereby translating the weave pattern information into mechanical motion. At this time, the solenoid actuator is provided with a cap having a protrusion extending toward the contact side with the electrode plate at the distal end of the solenoid actuator. It comes into contact with one pole plate of the permanent magnet structure only at
In other parts, a certain gap is formed between the electrode plate and the contact area between the two becomes very small. As a result, the amount of oil present in the contact portion is reduced, and the influence of oil contamination on the switching operation of the solenoid actuator is almost eliminated, and the operation of the solenoid actuator becomes more reliable.
