There is also a device including a pair of guides having a plurality of guide grooves having a U-shaped cross section, and a plurality of movable mounting bodies having receiving grooves extending in the up-down direction so as to receive the edge portion of the heald frame. The guides are immovably attached to the left and right frames of the loom so that the guide grooves face each other, and the movable attachment body is fitted in the guide grooves so as to be vertically movable.

The upper end of the movable mount is connected to the spring mechanism via a rope connected to the movable mount and a jack lever connected to the rope. On the other hand, the lower end portion of the movable mounting body is connected to a drive mechanism that moves the movable mounting body in the vertical direction in cooperation with the spring mechanism by another rope. The heddle frame, after the side stays at both ends thereof are inserted into the receiving grooves of the pair of facing movable mounting bodies from above, is detachably mounted to the corresponding movable mounting body. By moving up and down, it is moved up and down.

(Problem to be Solved) However, in the conventional supporting device, the movable mounts that face each other are displaced in the direction toward each other before the attachment of the heald frame, and the distance between the movable mounts becomes smaller than a predetermined value. Sometimes. In the conventional heald frame support device, if the play between the guide and the movable mount is large, the movable mount is often twisted by the torque of the rope.

In this way, if the relative positional relationship between the facing movable mounting bodies is deviated, the relative positional relationship between the facing movable mounting bodies must be corrected when the heald frame is mounted on the movable mounting body. Therefore, in the conventional supporting device, the work of mounting the heddle frame is troublesome, and the machine tool that automatically delivers the heddle frame, especially the machine that automatically delivers a plurality of heddle frames collectively. It interferes with the delivery by the in-process device.

An object of the present invention is to provide a supporting device for a heddle frame in a loom, in which opposing movable mounts are maintained in a predetermined positional relationship.

A heald frame supporting device in a loom according to the present invention has a plurality of vertically extending guide portions, and a pair of guides arranged so that the guide portions face each other, and the guide portions are vertically movably received by the guide portions. Also, a plurality of movable mounting bodies having a guided portion at least a part of which is made of a magnetic material and having a portion for receiving the edge portion of the heald frame, and a magnetic force for moving the movable mounting body toward the guide portion. And a magnetic element that acts on the guided portion.

Another supporting device according to the present invention has a plurality of guide portions extending in the vertical direction and at least a part of which is made of a magnetic material, and a pair of guides arranged so that the guide portions face each other, and the guide portion. A plurality of movable mounting bodies each having a guided portion that is vertically movable, and a portion that receives an edge portion of the heald frame; and a guided portion of the movable mounting body, and a bottom portion of the guide portion. And a magnetic element embedded in a portion corresponding to.

The magnetic force generated from the magnetic element acts on the movable mounting body so as to move the opposing movable mounting body toward the guide portion. As a result, the guided portion of the opposing movable mounting body is attracted or pressed by the corresponding guide portion by the magnetic force of the magnetic element. For this reason, according to the present invention, the distance between the opposing movable mounts is automatically maintained at a predetermined value.

It is preferable that the cross-sectional shapes of the guide portion and the guided portion are similar to each other. As a result, the guided portion of the movable mounting body comes into proper contact with the guide portion similar in shape to the guided portion, so that even if there is some play between the guide portion and the guided portion, the twisting of the movable mounting body will occur. Is prevented.

When the contact surface between the guide portion and the guided portion is flat, the movable mounting body is prevented from being twisted even if there is some play between the guide portion and the guided portion. In this case, the cross-sectional shapes of the guide portion and the guided portion can be U-shaped.

The movable mounting body 20 has a receiving groove 26 having a U-shaped cross section that extends in the longitudinal direction at a portion received by the guide groove 24, that is, a portion opposite to the rear portion, that is, the front portion.

As shown in FIG. 1, the upper end of each movable mounting body 20 is known via a rope 28 connected to the movable attachment body 20 and a known jack lever 30 connected to the rope and pivotally supported on the frame 12. Is connected to the spring mechanism 32. On the other hand, the lower end of the movable mounting body 20 cooperates with the spring mechanism 32.
A known drive mechanism (not shown) for moving the 20 up and down
Is connected by a rope 34.

As shown in FIGS. 2 and 3, the magnet assembly 22 includes a prism-shaped block 36 made of a non-magnetic material, and a plurality of magnetic elements 38 arranged in the block 36 corresponding to the movable mount 20. Equipped with. The magnetic element 38 is arranged so that one magnetic pole surface faces the rear surface of the corresponding movable mounting body 20. An electromagnet or a permanent magnet can be used as the magnetic element 38.

When a permanent magnet is used as the magnetic element 38, a low coercive force magnet such as an alnico magnet may be used, or
A magnet with a high coercive force such as a ferrite magnet or a rare earth metal magnet may be used. When an electromagnet is used as the magnetic element 38, an iron core may be used instead of the exciting coil,
It is not necessary to use the iron core.

When either an electromagnet or a permanent magnet is used as the magnetic element 38, one magnetic element may be commonly used by the plurality of movable mounting bodies 20, and a yoke may be further used. When one magnetic element is commonly used by a plurality of movable attachment bodies 20, the magnetic element or a yoke magnetically connected to the magnetic element can be opposed to the plurality of movable attachment bodies 20.

The guide 18 is made of a non-magnetic material. On the other hand, the movable mounting body 20 is made of a magnetic material. However, the movable mount 20
Only the rear part may be made of a magnetic material.

The heddle frame 40 has side stays at both ends thereof inserted into the receiving grooves 26 of the pair of movable mounts 20 facing each other from above, and then detachably attached to the corresponding movable mounts 20. By moving the movable mounting body 20 in the vertical direction, the movable mounting body 20 is moved in the vertical direction.

According to the support mechanism 14, since the movable mounting body 20 is attracted into the guide groove 24 by the magnetic element 38, the rear surface of the movable mounting body 20 is in contact with the bottom of the guide groove 24. Therefore, the distance between the pair of movable mounts 20 facing each other is maintained at a predetermined value determined by the distance between the guides 18 facing each other. The stay can be placed in the receiving groove 26.

Further, since the cross-sectional shape of the guide groove 24 and the shape of the outer surface of the rear portion of the movable mounting body 20 are U-shaped, the bottom portion of the guide groove 24 and the rear surface of the movable mounting body 20 contacting the bottom portion are in contact with each other.

In many cases, the movable mounting body 20 is twisted with respect to the guide groove 24 by 8 and 34, and the relative positional relationship between the facing movable mounting bodies 20 shifts. If the relative positional relationship between the facing movable mounting bodies 20 is deviated in this way, the relative positional relationship between the facing movable mounting bodies 20 must be corrected when the heald frame 40 is mounted on the support mechanism 14.

Therefore, according to the support device, the heald frame 40 is supported by the support mechanism 14
Since it is not necessary to correct the relative positional relationship between the movable mounts 20 that face each other when mounted on, it is possible to easily collectively deliver a plurality of heddle frames collectively by means of an in-process device or the like.

The cross-sectional shape of the guide groove 24 and the shape of the outer surface of the rear portion of the movable mounting body 20 are preferably U-shaped as in the above embodiment, but may be other shapes such as a semicircle and a V-shape. Good.
However, it is preferable that the cross-sectional shape of the guide groove 24 and the shape of the outer surface of the rear portion of the movable mounting body 20 are similar shapes.

After the heald frame 40 is attached to the movable mount 20, it is preferable to keep the magnetic element 38 away from the movable mount 20. To do this, for example, when the block 36 is screwed to the guide 18, the screw hole of the block 36 may be a long hole.

The magnetic element 38 may be embedded in the bottom portion of the guide groove 24 of the guide 18 so as not to affect the vertical movement of the movable mounting body 20, that is, so as not to be in direct contact, or the rear end portion of the movable mounting body 20. It may be embedded at a position corresponding to the guide groove 24.

When the magnetic element 38 is embedded in the rear end portion of the movable mounting body 20, the movable mounting body 20 may be made of a non-magnetic material, and the guide 18 and particularly the portion defining the guide groove 24 may be made of a magnetic material. For example, as shown in FIG. 6, the guide groove 24 is made of resin or the like because of the function of a guide, and the magnetic material 42 is formed on the bottom of the guide groove 24.
Is preferably embedded.

When an electromagnet is used as the magnetic element 38, it is preferable to act the electromagnet only when the heald frame 40 is attached to the support mechanism 14. As a result, when the heddle frame 40 is removed from the support mechanism 14 and when weaving, the magnetic field of the electromagnet is not affected.

Instead of forming the guide groove 24 in the guide 18 and forming the portion fitted in the guide groove 24 in the movable mounting body 20, a long protruding portion extending in the vertical direction is formed in the guide 18, and the movable mounting body 20 is formed. It is also possible to form a groove into which the protrusion is fitted. Similarly, a projecting portion for receiving the heddle frame 40 is formed on the movable mounting body 20, and
Grooves that fit into the receiving protrusions may be formed in the side stays at both ends of 40.
