Description

DETAILED DESCRIPTION OF THE INVENTION The invention is a device for feeding a spool to a creel, comprising a winding device that can be driven by a motor and an operating device held by the winding element of the device. The operating device includes a handle, a piston with a tightening device for insertion into the spool sleeve,
The present invention relates to a device comprising auxiliary means for pivoting the spool shaft from a vertical position to a horizontal position and an operating device for transmitting a switching signal for motor control.

When installing spools on a creel, each spool is removed from the packaging box in which it is placed on its vertical axis, turned 90°, moved to the appropriate height, and
Must be attached to the creel shaft. In this case, a fairly large capacity spool is used;
It weighs between 0 and 13 kg. Handling these spools requires a great deal of effort. Nowadays, creels with more than 1000 spools are in use, so attachment to the creel is labor intensive without the use of an auxiliary means.

Therefore, a device of the type described at the beginning (Felc.

-Air Balancer) is known, in which the end of the piston protruding from the spool is
Fixed to the lower end of the seine used as a hoisting element. The piston is tightly clamped to the spool sleeve by air. The piston includes two spaced apart handles that rotate the spool to move the spool axis from a vertical position to a horizontal position. At the handle there is an operating device for operating the air set clamp and controlling the motor.

Significant labor savings have been achieved with the device described above. However, in this case as well, the operator in principle has to reach out with two hands and, in particular, requires a relatively large amount of force to pivot the spool.

The object of the invention is to provide a device of the type mentioned at the outset, in which spools, especially heavy high-capacity spools, can be manipulated with very little force and can be operated with only one hand. be.

These 11 problems are solved by the present invention as follows.

That is, the auxiliary means for turning is an arc-shaped guide element connected to the piston and the handle, the axis of which cuts around the center of gravity of the spool to which the piston axis is attached, and the guide element. The solution is achieved by providing the movable support with a bearing which is attached to the winding element.

In such a configuration, the spool pivots about the spool's center of gravity after the piston is inserted into the spool sleeve. The rotational torque required for this is extremely small. What is correspondingly smaller is the force used by the operator. Therefore, it can be operated with one hand, and can even be operated by a handicapped person, for example, a one-handed operator.

It is advantageous if the bearing is provided with rollers on both sides of the guide element. This significantly reduces friction on the bearing. This is particularly effective when the roller itself is equipped with ball bearings. Therefore, the operating force becomes even smaller.

Furthermore, in a preferred embodiment of the invention, the end of the guide element cuts the piston axis and is connected to the piston via a bar extending obliquely to the piston axis on the side of the element facing the bearing. ing. Therefore, the bearing part is located exactly in the extension of the spool axis when the piston is inserted into the spool sleeve and when the spool is lifted out of the packaging box. Therefore, it is possible to take it out vertically.

Furthermore, one handle can extend on each side of the guide element. This device is suitable for both right-handed and left-handed people in the same way.

In another configuration of the invention, the tightening is such that the device is manually and mechanically operable. In this way, conductors, such as compressed air tubes or electrical cables, for supplying auxiliary energy and which interfere with the light pivotability of the operating device are eliminated.

By eliminating such an auxiliary motor, the operating device becomes even lighter. On the other hand, tightening the mechanical operation of the device is not complicated. This is because a sufficient tightening requires relatively little hand force to exert force.

In a preferred embodiment, the tightening device comprises an opening element which can be opened relative to the hollow insert surrounding the piston by annular movement of the piston. Also provided is an eccentric plate adjustable by a rotary handle for circular movement of the piston. By partial rotation of the eccentric plate, the piston is moved far enough to push the opening element outwards.

It is further advantageous to provide a signal transmission device for wirelessly transmitting the switching signal, the device comprising a transmitter located at the handling device and a receiver connected to the motor. ing.

In this way, the signal wires that conventionally connected the handling device to the motor are also eliminated.

Particularly suitable are infrared signaling devices.

The device is largely undisturbed under certain operating conditions. Other wireless transmissions may also be possible, such as by radio waves, ultrasonic signals, radio signals, and the like.

Next, the present invention will be explained in detail with reference to embodiments shown in the drawings.

The creel knife shown in FIG. 1 has a shaft 2 for mounting spools 3 in a plurality of rows or stages. The spool is delivered in a box 4. Here, the axis 6 is oriented longitudinally with the sleeve 5 of the spool.

The lower end of the sleeve stands on a protrusion 7 that prevents it from slipping off. The feeding device 8 of the spool 3 to the creel 1 includes a winding device @9 and an operating device 10.

The hoisting device 9 comprises a hoisting element I, in the form of a seine 11, which seine consists of two rollers 12 and 13.
The winder 15 can be rotated by a motor 14 to wind up the winder. A motor 14 with rollers 12 and 13 and a winder is mounted on a support 16, which supports pivot 1
It is held on a truck 18 so as to be rotatable about 7. The truck is movable along two rails 19.

The actuating device 10 comprises a piston 30, which is surrounded by a hollow insert 20 and is inserted from above into the sleeve 5 of the spool 3, where it is tightened by the tightening means described below.

The ring 21 ensures that the insert 20 always enters the sleeve 3 to the same depth. A diagonally standing bar 22 is connected to the piston 30, and the bar is
At the outer end, the handle 2 stands upright in the plane of the drawing.
It supports 3 and 23a. A curved guide element 24 extends from this bar 22 and forms an arc of approximately 120 DEG about an axis 25 . The axis cuts the common axis 6 of the piston 30 and the sleeve 5 at the center of gravity of the spool 3 when the spool 3 is in a free-flowing state. In the starting position shown in FIG. 2, in which the piston 30 is inserted from above into the spool in the packaging box 4, in the extension of the axis 6 there is a bearing 26 with three rollers 21 which displaceably receive the guide element 24. be.

After the spool is lifted by the winding device 9,
By grasping the handle 23, the spool 3 is moved to the third position.
The spool axis 6 can be easily rotated to the horizontal position shown in the figure. This is because the center of gravity 25 of the spool 3 is always located below the bearing 26 during such a pivoting movement. The spool can therefore be brought into a position where it can be inserted directly into the shaft 2 by simply manipulating the winding device and possibly by shifting or pivoting the support 16.
All you have to do is be carried.

At its lower end, the insert 20 has one or more rows of openings 28 in which balls 29 are arranged as expansion elements. By appropriately shaping the opening 28, these balls are prevented from falling out. The piston 30 is provided with a bevel 31 so that the upward annular movement pushes the expansion element 29 outwards towards the sleeve 5 . The support plate 3 is attached to the bar 22.
2 is attached, and the support plate is fixed to the piston 30 by screws 33. A rotating shaft 34 is supported in the piston 30, which supports at each end one eccentric plate 35 or 35a which supports itself on the ring 21 and which is further guided into a handle 36. Supports the lever arms 31 to 37a. A spring 38 connects this axis of rotation 34 with the bottom 39 of the bayonet 20 and prevents the hollow bayonet 20 from moving away from the piston 30. The insert is therefore essentially intended only for supporting the ball 29. Therefore, the handle 36 is
By pivoting in direction 0, the piston 30 is moved in an annular manner, so that the insert 20 with the ball 29
is tightly tightened within the sleeve 5 or left free. Only a small amount of manual effort is required here.

Each handle 23 and 23a has an operating device 41 or 41a. Each infrared transmitter 42 to 42a
and operating elements, e.g. pushbuttons 43 to 43a.
It is made up of. An infrared receiver 44 is attached to the support part 16.
The receiver is equipped with a transmitter 42 to 42a.
It receives an infrared signal and provides a corresponding switching signal to the motor 14.
