Description

[Detailed description of the invention] The present invention relates to an opening device for a diagonal line vertical frame.

Even in opening devices where the heddle frame is installed diagonally (tilting forward) due to the structural needs of the loom, the dobby machine or cam machine is mounted horizontally, and the shaft of the jack lever is horizontally mounted. It is common that the

The reason for this is that gravity acts on the lever attached to the dobby machine, etc., so it tends to swing in directions other than perpendicular to the shaft, and to prevent parts from coming into contact with each other and wear out, or to prevent lubricating oil from being worn out. This is to prevent a lack of lubricating oil due to the flow down in an inclined direction. However, the connection mechanism between a horizontally disposed dobby machine or the like and an obliquely disposed horizontal vertical frame is not suitable when the picture frame is vertical, and must be considered separately.

Here, "
A "closing device for diagonal heald frames" has been proposed, but this device requires connecting members with specific lengths depending on the order in which the heddle frames are arranged, which is inconvenient both in the manufacturing stage and in the use stage. There are many drawbacks. In view of the above, it is an object of the present invention to provide an opening device for a diagonal heddled paper frame that uses common members for both the front and rear green paper frames.

The gist of this invention is to connect an obliquely installed heddle frame and a horizontally installed dobby machine, cam machine, etc. with a hanging rope, and guide this hanging rope with guide pulleys placed at two positions. In this structure, the shaft of the guide pulley close to the heddled paper frame is provided obliquely in the same way as the heddled paper frame.

The configuration of the present invention will be explained below with reference to the illustrated embodiments.

In FIGS. 1 and 2, a plurality of heddle frames 1 are tilted forward at a predetermined angle (the right side in FIG. 2 is referred to as the front), and are fixed to a machine frame (not shown). It is mounted so that it can be moved up and down while being guided by a guide member that does not move. A hanging rope 2 is connected to the upper part of both the left and right ends of each line paper frame 1,
The end of the hanging rope 2 is connected to a jack lever 4 of a dobby machine 3 installed horizontally. A fixed shaft 5 supporting the jack lever 4 is arranged horizontally. 6
is a diagonal shaft, and its both ends are fixed to a machine frame that is perpendicular to a plane parallel to the front and rear surfaces of the vertical heald frame 1 above near both left and right ends of the heddle frame 1, and the diagonal shaft 6 A grooved guide pulley 7 is rotatably mounted opposite each heddle frame 1.

Reference numeral 8 denotes a horizontal shaft, and the horizontal shaft 8' is rotatably iron-mounted with a grooved guide pulley 7, which faces the guide pulley positioned at the center of the grooved guide pulleys 7 on the oblique shaft 6. The hanging rope 2 between the grooved guide pulley 7 on the horizontal shaft 8 is formed to be horizontal and parallel to the front and rear surfaces of the heddle frame 1, and each grooved guide pulley 7 is connected to the center of each shaft. They are later arranged symmetrically as a center of symmetry.

As shown in FIG. 1, the hanging rope 2 is stretched so as to be guided by a grooved guide pulley 7 on an oblique shaft 6 and a horizontal ball 8. Note that the governing frame 1 is urged downward by a spring (not shown). In this device, when the jack lever 4 swings, the hanging rope 2 is guided by the grooved guide pulley 7 on the horizontal shaft 8 and the grooved guide pulley 7 on the oblique shaft 6 to move the heddle frame 1 up and down.

In this case, the hanging rope 2 and jack lever 4 are located between the grooved guide pulley 7 on the oblique shaft 6 and the heddle frame 1.
The hanging rope 2 at the part between the grooved guide pulley 7 on the horizontal shaft 8 and the grooved guide pulley 7 on the horizontal shaft 8 is connected to the hanging rope 2 at this part because the direction of entry of the hanging rope 2 and the direction of rotation of the grooved guide pulley 7 are the same. will not come off from the grooved guide pulley 7. Furthermore, the hanging rope 2 located between the grooved guide pulley IJ7 on the oblique shaft 6 and the grooved guide pulley 7 on the horizontal shaft 8 in the center in the longitudinal direction is horizontal and parallel to the front and rear surfaces of the heddle frame 1. Therefore, since the direction in which the hanging rope 2 enters and the direction of rotation of the grooved guide pulley 7 match, the hanging rope 2 does not come off the grooved guide pulley 7. The grooved guide pulley 7 on the oblique shaft 6 and the grooved guide pulley 7 on the horizontal track 8 corresponding thereto are located at the center, but the other grooved guide pulleys 7 are located between these grooved guide pulleys 7 as they move away from the center. The degree of agreement between the direction of entry of the hanging rope and the direction of rotation of the grooved guide pulley 7 at a certain point gradually decreases, but the rate of decrease is extremely low, and this is due to the fact that the pulley is of the grooved type. The hanging rope 2 does not come off from the grooved pulley 7.
The hanging rope 2 is guided by a grooved guide pulley 7 so that the heddle frame 1 can be raised and lowered. According to the present invention, as described above, since the grooved guide pulley of the same shape and the same type of hanging rope are used for a plurality of heddle frames, it is easy to manage during manufacturing and use, and it is economical. is also large. In addition, in the above-mentioned embodiment, among the hanging ropes between the grooved guide pulleys on the oblique shaft 6 and the horizontal shaft 8, the rope located at the center in the front and back direction is formed to be horizontal, but it does not necessarily have to be horizontal. As long as it is parallel to the front and rear surfaces of the heddle frame, it is sufficient.
