Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a ring plate position adjusting device such as a ring spinning machine and a ring twisting machine.

(Prior Art) In a ring spinning machine or the like, the ring plate is moved up and down in synchronization with the rotation of the roller part to form a yarn. Since the position of the ring plate at the beginning of winding directly affects the shape of the yarn, if the ring plate is removed during maintenance work such as the spinning machine stand or after the occurrence of a thread breakage common to all spindles due to a power failure, etc. When restarting, it is necessary to adjust the height of the ring plate. Conventionally, the position adjustment of the ring plate has been performed by attaching a handle to a rotary shaft to which a shaper wheel is fitted and allowing an operator to manually rotate the handle.

(Problems to be solved by the invention) However, when raising and lowering the ring plate by a manual operation, there is a problem that the handle has to be turned many times for the raising and lowering operation of the ring plate, which is a troublesome work.

SUMMARY OF THE INVENTION An object of the present invention is to provide a ring plate position adjusting device capable of independently moving up and down by separating a ring plate from a drive system on a roller part side by operating a switch.

(Means for Solving the Problems) In order to achieve the above-mentioned object, in the present invention, the power transmission from the roller part side is input to a power transmission system that performs the vertical movement of the ring plate in synchronization with the rotation of the roller part. A clutch for disengagement was provided, a motor capable of rotating the ring plate drive system was provided on the ring plate side of the clutch, and a manual switch for instructing the operation of the clutch and the motor was provided.

(Operation) In the device of the present invention, when the position of the ring plate is adjusted, when the operator operates the manual switch to instruct the ring plate to move up or down, the clutch operates and the power from the roller part side is activated. In the state where the transmission is blocked, the motor is driven in the forward or reverse direction in response to the up or down movement by the instruction of the manual switch, and the ring plate is moved up or down.

(Embodiment 1) The present invention will be described below, for example, in a lifting device having a structure in which a ring plate and a lappet angle are moved up and down in response to forward and reverse rotations of a line shaft, as in the device disclosed in Japanese Patent Laid-Open No. 62-133129. An embodiment embodied in the apparatus will be described with reference to FIGS. As shown in Fig. 1, the longitudinal direction (left and right direction in Fig. 1) of both sides of the spinning machine stand.

The slide clutch 39 meshes by the action of a clutch 41 directly connected to the shaper shaft 40 and a spring 42, and a worm 43 connected to the slide clutch 39 via a spline rotates in the same direction as the shaper wheel 44. The pulley 45 is rotated, and the lifting chain 46 is wound and unwound. This allows the ring rail to move up and down with or without the action of a heart cam (not shown). On the other hand, a toothed pulley 47 is fixed to the end of the shaper shaft 40,
The rotation of the swing motor 36 is transmitted to the toothed pulley 47 via the worm 48, the worm wheel 49, the electromagnetic clutch 50, the toothed pulley 51, and the toothed belt 52. The lever 53 for switching the engagement of the slide clutch 39 is arranged at a position where the slide clutch 39 engages with the clutch 41 by the action of the spring 42 when the solenoid SOL is in the demagnetized state, and the slide clutch 39 has the clutch teeth when the solenoid SOL is in the excited state. It is arranged at a position where it meshes with the gear 38. The solenoid SOL

Therefore, in this device, the switch 55
Alternatively, when the switch 56 is pressed, the electromagnetic clutch 5
0 is excited and the swing motor 36 is driven to rotate normally or reversely, and the worm 48, worm wheel 49, electromagnetic clutch 50, toothed pulley 51, toothed belt 5
2, the pulley 45 is rotated via the toothed pulley 47, the clutch 41, the slide clutch 39, the worm 43, and the worm wheel 49, and the ring plate and the lappet angle are moved up and down via the lifting chain 46.

(Effect of the Invention) As described in detail above, according to the present invention, when the position of the ring plate is adjusted while the machine base is stopped, the operator operates the switch to move the ring plate up and down by driving the motor. This makes it easier for workers. Further, since the motor moves up and down, the up and down speed of the ring plate can be increased. Further, the spinning machine provided with the swinging mechanism of the ring plate when the pipe is fully stopped can be implemented only by adding a simple control circuit and a lifting switch.
