Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a heald frame of a loom, and particularly to a heald frame suitable for a high-speed loom.

<Prior Art> A heald frame is constructed by suspending a pair of upper and lower carrier rods in parallel on a heald frame body that is framed by upper and lower frame staves and left and right side stays. It is loaded so as to extend between carrier rods. Further, when the frame length is long, the carrier rod is bent during operation, and in order to prevent this, the carrier rod is suspended and supported from the frame stave by a middle hook in an appropriate position.

The structure of the conventional middle hook 20 is as shown in FIG. 3, and has a rod hole 21, and an opening 22 is formed on the side surface of this lock hole 21, and the carrier rod 23 has this opening 22.
Be moved in and out through. Notch 22 dimensions are carrier rod
Since it is smaller than 23, the carrier rod 23 is twisted a little when going in and out. In addition, for this insertion and removal, rod hole 21
Is longer than the carrier rod 23.

<Problems to be Solved by the Invention> However, in the above-mentioned conventional one, since the rod hole 21 is larger than the carrier rod 23, a gap is generated between the two in the fitted state, and rattling occurs during operation. In the case of a low-speed running loom, looseness is not a particular problem and does not hinder the weaving work.However, in a high-speed loom, this looseness is serious and may cause damage to the healds and vibrations. Have a great adverse effect on work.

Furthermore, in the conventional case, the work of fitting and removing the carrier rod 23 and the middle hook 20 must be performed manually by one place, and in a loom loaded with many heald frames, this work requires a lot of time. Is required and there is a problem in work efficiency.

In view of the above points, the present invention provides a heald frame that has no play in the fitting state of the carrier rod and the middle hook and that can perform the fitting / removal work of this fitting extremely efficiently. It is a thing.

<Means for Solving the Problems> The technical means of the heald frame of the present invention include a heald frame body, a carrier rod provided so as to be parallel to a frame stave of the heald frame body, and a carrier rod attached to the frame stave. The middle hook has a rod hole that fits tightly with the carrier rod, and the side face of the rod hole is formed with an opening, while the carrier rod is formed with a notch. The carrier rod can pass through the opening of the middle hook and fit into and out of the rod hole only at the position of the notch.

<Operation> In the heald frame of the present invention, since the carrier rod is closely fitted to the rod hole of the middle hook, it does not rattle in the fitted state. The carrier rod can pass through the opening of the middle hook only in the cutout position, and cannot pass in other positions. Therefore, it is necessary to align the two when fitting in and out of the rod hole. In addition, if the carrier rod is slightly moved during operation so that the position of the middle hook and the position of the notch of the carrier rod are different from each other, the carrier rod will not accidentally slip out of the rod hole. Furthermore, since the attachment position of the middle hook and the formation position of the notch correspond to each other, if the position is adjusted in one place, the position can be automatically adjusted in all places and the carrier rod can be attached / detached with one touch. Can be done easily with.

<Embodiment> An embodiment of the heald frame of the present invention will be described with reference to the drawings. The heald frame body 1 is composed of a frame stave 2 that serves as an upper and lower frame and a side stay 3 that serves as a left and right frame, and is framed into four corners. A carrier rod 4 is provided along each of the upper and lower frame staves 2, and the heald 5 is loaded so as to span the upper and lower carrier rods 4. Further, the carrier rod 4 is supported by a middle hook 6 at an appropriate position so as not to bend and deform.

The middle hook 6 has a rod hole 7, and an opening 8 is provided on the side surface of the rod hole 7. The rod hole 7 has substantially the same size as the cross section of the carrier rod 4 so that no gap is created between the rod hole 7 and the carrier rod 4 in the fitted state. The carrier rod 4 and the rod hole 7 are inserted and inserted through the opening 8. However, since the vertical dimension A of the opening 8 is smaller than the vertical dimension B of the carrier rod 4, it is not possible to fit or insert it in the normal position, and only the position of the notch 9 provided in the carrier rod 4 is possible. is there. This notch 9 is a carrier rod 4
Is formed in advance, the dimension C of the carrier rod 4 substantially coincides with the opening dimension A at the position of the notch 9, and the opening 8 can pass only at this position.

In the illustrated embodiment, the middle hook 6 is a hook hanger 10.
It is attached to the frame stave 2 by. Further, the middle hook 6 and the hook hanger 10 are detachable, and the hook hanger 10 is fixed to the inner edge of the frame stave 2. However, the mounting position of the hook hanger 10 is adjustable and can be fixed by moving it to a desired position.

Next, a method of using the heald frame will be described.
First, the position of each middle hook 6 is adjusted and fixedly set according to the position of the notch 9 of the carrier rod 4. Next, the carrier rod 4 loaded with healds is brought to the mounting position of the heald frame body 1, and the carrier rods 4
The position of the notch 9 is aligned with the position of the middle hook 6 and fitted into the rod hole through the opening 8. All middle hooks 6
After the fitting is completed, the carrier rod 4 is slightly slid and moved in either the left or right direction. By this slide, the positions of the notch 9 and the middle hook 6 are deviated, and the carrier rod 4 and the rod hole 7 are tightly fitted. The carrier rod 4 may be removed in the reverse order of the above.

In the heald frame of the present invention, the shape, position, and number of the notches 9 of the carrier rod 4 are arbitrary, and the structure of the middle hook 6, the shape of the rod hole 7 and the opening 8, and the middle for the frame stave. The attachment means of the hook 6 is not limited to the embodiment, and other types can be freely adopted.

<Effect of the Invention> In the heald frame of the present invention, since the support portion of the carrier rod by the middle hook does not rattle and the carrier rod can be surely prevented from bending, the carrier rod of the carrier rod can be prevented even during high-speed operation. There is little vibration, it is possible to prevent accidents such as cutting out of the heald, and stabilize the weaving work. Furthermore, since the carrier rod and the middle hook can be fitted / removed at all positions simultaneously and easily, the work efficiency of attaching / detaching the carrier rod is improved.
