DE9011877U1 - Snap-on chuck - Google Patents

Description

The invention relates to a slip-on chuck consisting of a base plate and a vertically fixed slip-on mandrel for bobbins or cops or tubes for their automatic transport from or to the spindles of a spinning machine, in particular a ring spinning machine or OE spinning machine. Such slip-on chucks are referred to as peg trays or bobbin trays.

From DE-GM 73 01 717 (AEG) it is known to put the cops produced by spinning machines on a slip-on chuck of the aforementioned type, which has a flat, polygonal - in the example there square - base plate. The purpose of the known slip-on chuck is to
to keep an individual inserted coil fixed during automatic transport. %o that harmful contact between the coil body of the coil and other coils, with walls or surfaces of a container is essentially excluded.

In a further development of the slip-on chuck, DE 37 12 027 (Toyoda.) provides an essentially circular base plate, the diameter of which is at most equal to the spindle spacing, i.e. equal to the so-called spindle pitch, of the spinning machine to be supplied or disposed of. If the diameter of the base plate is equal to the spindle pitch - or an integer fraction of the two - the slip-on chucks can be fed to the respective spindle position without touching one another when the cop is changed, by transporting the slip-on chucks in a rail so that they touch one another. If, on the other hand, the spindle pitch is larger than the diameter of the base plate and not equal to an integer multiple of this number, each base plate must be ground individually.

It has proven particularly advantageous if the base plates of the chucks have a clearance that is exactly the same as the spindle bore of ^the spindle machine being serviced, as this allows the best accuracy of the spindle to be achieved and the targeted spindle positions assigned to each spindle can be omitted. When further transporting and storing the chucks with the spindles attached, the spindle space remains the same. lung is decisive for the geyent.ei t. igen distance ^r i ^e '<&Iacgr;"&idiagr; \ igen <■ opse .

Since all the bobbins are pulled off at the same time during doffing (removal of the bobbin from the spinning machine), the bobbins assigned to the individual spinning machine are not for the ^purpose of transporting ^{the bobbins} . The situation is different when the bobbins with the bobbins attached are to be transported from the spinning machine to a winding machine. Here the spinning bobbins are exchanged individually, namely whenever a bobbin has run in. A certain supply of bobbins should therefore be made available at each winding station in such a way that a new bobbin can be moved up immediately for each winding station when the bobbin is removed.

The clip-on chucks according to the invention can be transported using a belt conveyor system. Other transport systems are also possible. This includes, for example, a cop transport system using an air cushion conveyor system, ^v;-.before an air blow hole in the conveyor surface

conveyor track and guide rails on the longitudinal edges of the conveyor track.

In an air cushion conveyor system, a static pressure is generated in a closed channel under the conveyor track by one or more fans. The air accumulated in the channel flows out through the holes provided in the conveyor surface and, depending on the shape of the holes, generates a lifting component through a conveyor component on the objects to be transported.

Copies or tubes that practically only lie in one line on a flat surface are difficult to transport on an air cushion conveyor system. However, an air cushion conveyor system using the plug-on chucks can be designed in such a way that it is at least as good as a cop transport system as ^a transport system, for example.

Details of the invention are explained using the schematic representation of embodiments. They show:

Fig. 1 is a perspective view, partly in L section, of a slip-on chuck with rectangular base plate and mounted bobbin; and

Fig. 2 shows a view of a rectangular base plate modified to an octagon.

The slip-on chuck according to Fig. 1, designated as a whole with 1, consists of a base plate 2 and a vertically fixed mandrel 3 for cops 4 or tubes 5 for their automatic transport from or to the (not shown) spindles of a spinning machine or winding stations of a winding machine. According to the invention, an essentially rectangular base plate 2 is provided, whereby the length of one, larger rectangular side 6 of the base plate 2 should be equal to the spin pitch of the spinning machine and the length of the other, shorter rear side 7 should be approximately equal to the outside diameter of the other cops 4. Addition: The length of the respective side of the rectangle could be equal to an integer fraction including I/I of the division of the (not shown) spool reel of a track machine to be connected downstream of the spinning machine.

Since the mutual distance between the mandrels 3 is then exactly the same as the distance from spindle to spindle of the spinning machine, incorrect positioning will not occur during the simultaneous transfer of the finished spinning cops 4 from the spindles of the spinning machine to the slip- on chucks 1.

For further transport, a plug-in chuck 1 can be mounted on the etched Korean 4, so as to save storage or transport space. If necessary, the individual plug-in chucks 1 are each rotated 90° around a vertical axis, e.g. on a conveyor, so that the long rectangular sides ¹ , 6 now lie against one another. However, it is clear that the length of the short rectangular sides 7 should still be large enough so that the bodies of adjacent cops 4 cannot rub against one another.

Since - as mentioned - the rectangular shape of the base plate 2 can cause difficulties if curved elements are provided in the conveyor track provided for the plug-on chuck 1, the rectangular shape of the base plate 2 can preferably be modified to a type of octagon by "bending" all the rectangular edges 6, 7 along their respective centers 8, 9 as the pivot point, as shown in Fig. 2, in such a way that the mutual distance between opposite centers Q of the rectangular edges Q corresponds to the angle d of the chuck 4, a y-numbered fraction (one half 1/1) of the division of the rectangular edges I ^{, I} , ^etc. -ud the mutual distance between opposite centers 8 corresponds to the longest rectangle ■■&bull;sides <■> of the pitch of the spindles.
