Description

Spider holders are already known to enclose a fixed support ring connected to the spindle and provided with a V-shaped and the like spring that can be pressed by hand when the coil is put on the bobbin holder and securing the spool on it when the arm is removed from the spring. Spider holders of this type, which are used, in particular, on silk-reeling machines and the like, are usually adapted for putting coils or cartridges on them with approximately the same shape and dimensions of their internal channel, for example, for conical or cylindrical coils of a certain size and this is their disadvantage is that they do not allow the use of these spider holders for coils of different shapes and sizes.

The proposed holder for warping machines is intended to eliminate the above-mentioned disadvantage of already known spider carrier. The body has a support ring and a securing spring and is different in that its spring is stepped in shape to hold coils with sharply different sizes of internal diameters.

Such a shape of a bobbin holder according to the invention extends its field of use and constitutes its advantage over the already known bobbin holders of the same type.

FIG. I am given a front view, partially in. a cut, shpledderder according to the invention; in fig. 2 is a cross section of the bobbin holder of FIG. one; FIG. 3 is a front view of the bridal holder of FIG. 1 when used for cylindrical coils.

The spindle / shpuleder rigidly attached to the bracket 2, and along the lower generatrix the spindle is provided with a groove 3, like a key. To the spindle / rigidly attached is the end of the shaped curved spring 4, equipped with a step 5 in the middle part and a handle 6 on the free end. Tilting 5 to spindle axis / respectively. taper to the same axis of the inner surface of the conical chuck 7. A spindle / transverse axis, slightly protruding beyond its end, has a wire support ring 8, both of which are bent out of which are rigidly embedded in the opening of the bracket 2. The latter can be provided with a transverse process 5 located opposite to the handle 6 of the spring 4 and intended for the stop large. when you press handle 6 towards the spindle axis.

The spider holder is suitable for use as cylindrical ka.

bushings and conical cartridges with sharply differing sizes of internal diameters.

In order to center the conical chucks 7 on the axis of the spindle / axis of the // ends of the ring 8, inclined to the axis of the spindle 1, respectively, the cone of the cartridge, and the stage 5 of the spring 4 form angles of 120 ° between them, which leads to a symmetrical distribution of their pressure on the inside of the cartridge 7. To put the conical cartridge 7 on the bobbin holder 7, the handle 6 of the spring 4 is slightly pressed in the direction of the spindle axis /, put the cartridge over the ring 8 on its ends and on the level 5 of the spring 4, move the end of the cartridge 7 to the bracket 2. When releasing the handle. The spring 4, in its step 5, interacts from the inside with the chuck 7 at the length of the step 5 and secures the cartridge to the bobbin holder.

When the handle 6 is pressed, the cylindrical coils 10 move towards the V-shaped protrusion, the end of the spring 4 (Fig. 3) to the support ring 8, after which the handle 6 is released and both branches of the V-shaped end of the spring 4 act counter-negatively on the coil 10 , dock it.

Subject invention

A spider holder for warping machines with a support ring and its manually compressible spring, characterized in that the shaped spring 4 is made stepped so as to be able to hold coils with sharply different sizes of internal diameters.
