Description

[Detailed Description of the Invention] The present invention relates to a rappet reversing device for retracting the rappet, which becomes an obstacle, from its normal position when changing the pipe when the pipe is full in a spinning machine, a yarn twisting machine, etc.

In spinning machines, etc., a rotation shaft attached to the machine gear end side is used to simultaneously rotate the lappet angles, which are located on both sides of the machine frame and extend the entire length of the machine frame, on the left and right sides via levers, etc. This actuates the rappet attached to the angle. As such a rappet reversing device, one having a configuration as shown in FIG. 1 is known. That is, in this conventional device, a rotating shaft 1 passes through a gear end frame 2 from the gear end (left side in the figure) at the center of the machine, and a bearing bracket 3 that rotatably supports the rotating shaft 1 is bolted to the frame 2. 4,
4', and a pair of upper and lower arms 5 are attached to the portion where the rotating shaft 1 protrudes from the bearing bracket 3.
A rotating lever 5 consisting of a and 5b is attached. The arms 5a and 5b have pins 6a and 6, respectively.
b is implanted, and elongated holes 9 and 10 are drilled along the longitudinal direction at one end of the rods 7 and 8, and the pin 6
a and 6b are loosely fitted. The rods 7 and 8
extends to both sides of the machine, and the other end is the rappet angle 1.
Inversion brackets 11, 1 hanging down from 5, 16
2 by bolts 13 and 14 so as to be swingable. The rappet angles 15, 16 have a rappet 18 with a snell wire 17 attached to each weight. The angles 15 and 16 extend along the entire length of the machine toward the outside end, and are attached to a bracket 2 fixed to a lifting pillar 19 that moves up and down during winding operation.
0 and a mounting portion 21 fixedly attached to the angles 15 and 16 are connected via a shaft 22, and the angles 15 and 16 are rotatable about the shaft 22.

In the conventional apparatus having such a structure, the positioning operation for matching the reversal angles of the rappets 18 on both sides of the machine base is performed by adjusting the position of the bearing bracket 3 at the center of the machine base. That is, the operator loosely tightens the bearing bracket 3 to the gear end frame 2 with the bolts 4 and 4', and applies an appropriate external force to the bracket 3 to displace it so that the reversal angles of the rappets 18 on both sides of the machine match. When the proper position is secured, bolts 4 and 4' are firmly tightened and fixed. However, bearing bracket 3
Positioning operations by adjusting the position of the machine itself are extremely difficult, as it takes time to find matching points on the left and right sides, and requires the use of long tools that can reach the center of the machine for delicate work. Moreover, a large part depended on the intuition of the worker.

In order to eliminate the above drawbacks, the present invention aims to solve the above-mentioned drawbacks by
The rappet angles 15, 1 are constructed by attaching rappets 18 to each weight on both sides of the machine, focusing on the fact that both arms of the machine are attached symmetrically with respect to the axis of the rotating shaft 1.
The positioning operation of the rappet reversing device is facilitated by providing adjustment means for adjusting one rappet reversing angle to match the other so that the reversing angles of No. 6 are the same on both sides of the machine base.

Embodiments of the present invention will be described below with reference to FIGS. 2 and 3.
In FIG. 2, like the conventional device, a rotating lever 5 is fixedly attached to a rotating shaft 1 located at the center of the machine, and arms 5a and 5b extending from the lever 5 are aligned with the axis of the rotating shaft 1. It is symmetrical, and pins 6a and 6b are implanted at both ends, respectively. Of these, an elongated hole 9 at one end of a rod 7 extending from the center of the machine to the right side in the figure is loosely fitted into the pin 6a.
The other end is swingably connected by a bolt 13 to an inversion bracket 11 hanging down from the rappet angle 15. On the other hand, the rod 8 extending to the left in the figure has a long hole 10 at one end that loosely fits the pin 6b like the rod 7, but at the other end,
The rod 8' connected to the reversing bracket 12 is separate. An adjusting means for changing the distance between the two rods is interposed between the two rods 8, 8'. That is, the adjusting means has screw holes 24, 24' in which screws are carved in opposite directions to both rods 8, 8', a wrench hook 25 is fixed in the center, and screws are carved in opposite directions to each other. The adjustment screw 23 is composed of an adjustment screw 23.
are screwed into the screw holes 24, 24', thereby connecting the two rods 8, 8'. The rod 8' is pivotally connected by a bolt 14 to an inversion bracket 12 depending from a rappet angle 16. Moreover, other commercially available turnbuckles may be employed as the adjustment means. Snell wire 17
The rappet 18 equipped with this is attached to the rappet angles 15 and 16 on both sides of the machine base for each weight, and the rappet angles 15 and 16 on both sides of the machine base are pivotally supported on the bracket 20 of the lifting pillar 19. , is similar to the conventional device shown in FIG.

In the above configuration, when changing pipes, the rappet is retracted to a position as shown in FIG. That is,
The rotating shaft 1 is rotated at a predetermined timing by a drive shaft (not shown), and accordingly, the rotating lever 5 is rotated clockwise, and the arms 5a, which constitute the lever 5, Pins 6a and 6b attached to 5b
The rods come into contact with one end of the elongated holes 9 and 10 formed in both rods 7 and 8, and push both rods 7 and 8 simultaneously. As a result, both rods 7 and 8 cause the reversing brackets 11 and 12 to swing around the shaft 22,
The rappet angles 15 and 16 are reversed, and the rappet 18 is retracted to a position where it does not interfere with tube change. During the winding operation, the rappet 18 also moves up and down based on the lifting pillar 19, so the elongated holes 9 and 10 provided in the rods 7 and 8 act as a relief against the lifting movement of the rappet 18. , alleviating the impact at the time of reversal and return.

Of course, in order to increase the ability of both rods 7 and 8 to follow the rotary lever 5 during reversal and return, a spring, which is a conventional means, may be used, and in that case, it is further useful for alleviating the impact.

The reversal of the rappets 18 is performed only when the rappets 18 are at a certain height, but in order to match the angles at which the rappets 18 on both sides of the machine are reversed, positioning operations are performed as follows. First, adjust the frame 2 so that the angle of rappet inversion on the side where the adjustment screw 23 is not provided is at an appropriate angle.
Fix the bearing bracket 3 to. If the angle of inversion of the rappet is within the appropriate allowable range, the bracket 3 may be fixed immediately, so that this does not require much time. After fixing, the operator adjusts the distance between the rods 8 and 8' by turning the wrench hook 25 of the adjusting screw 23, which has reverse threads at both ends, to adjust the inversion angle of the rappet 18 on the left side of the figure. Complete by matching it to the right side of the figure. At this time, since the arms 5a and 5b of the rotating lever 5 are symmetrical with respect to the rotating shaft 1, the left and right rappets can easily obtain the same reversal angle. Furthermore, although the embodiments shown in Figures 2 and 3 have adjustment screws only on one side, if the adjustment screws are installed on both sides, the operator can perform positioning operations from either side of the machine base. It's advantageous.

As described above, by providing an adjustment screw on at least one rod, there is no need to perform positioning operations at the center of the machine to match the rappet reversal angles on both sides of the machine, making it easier for the operator. Since the position can be adjusted and this operation can be performed while the other rappet inversion angle is kept at an appropriate level, the inversion angles on both sides can be easily matched without relying on the operator's intuition.
