Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for transferring a set of yarn packages containing at least two pancages to a twisting machine, in which the yarn ends of the packages are separated from the package core before being transferred. placed inside.

When transferring a yarn package to a yarn making machine or yarn processing machine, considerable care must be taken in the arrangement and positioning of the yarn ends of the package. This is necessary both for the subsequent processing of the yarn package at the next working location and for safety reasons, since the situation of dropping the yarn end considerably interferes with the automated transfer.

In the transport of individual yarn packages, e.g. spinning boppins,
It is known to locate the thread end lying on the outer periphery of the boppin and place it inside the poppin core before transport (
In the case of twisting machines, several packages on which one yarn is wound are often fed to each twisting position, and the yarn end on each individual package is It is necessary to pay attention to the organization of

It is also known to combine several yarn packages fed to a twisting machine into sets of packages,
The individual yarn packages are then interconnected by chrysop bonds, which are known per se.

The object of the invention is to make it possible to transfer a set of yarn packages containing at least two packages to a twisting machine, and also to ensure that the yarn ends of all packages are confined and fixed during all stages of the transfer. On the one hand, the thread ends do not fall during the transfer, and on the other hand, all the thread ends are gripped jointly and automatically at the end of the transfer, thus making it possible to take up a position in which the thread ends are processed subsequently. The object of the present invention is to provide a method of the type described at the outset, which allows for easy handling of supplies.

Another object of the invention is to provide a device for carrying out the method described above.

These objects are achieved by making use of the features defined in the characterizing part of claim 1 of the invention. Further advantageous developments of the method according to the invention are the subject matter of claims 2 and 3.

Claim 4 describes and claims an apparatus for carrying out the method of the invention. Claims 5 to 11 describe further advantageous developments of the device claimed in claim 4.

The basic idea of the method of the invention is that the yarn packages that are to be joined into cents or stacks are interconnected by means of a package transfer adapter, which adapter is not removed from the set of packages upon completion of the transfer; It consists of interconnecting yarn packages forming sets or stacks, at which point they are processed simultaneously. This procedure involves placing the yarn ends of all packages of cents inside the package transfer adapter before transfer, and retaining the yarn ends within the adapter until the set of packages is inserted into the spindle of the twisting machine. enable.

In this way, it is made possible that the yarn ends of the packages do not change their common limited position, regardless of the particular location of the transfer and the type of conveying system used.

An embodiment of the method of the invention will be described in more detail below with reference to the drawings together with an apparatus for carrying out the method.

〔Example〕

Figure 1 shows two cross-wound packages of a single yarn, which are combined in a set or stack as a pair on a double-twisted yarn spindle. Forming a supply yarn package.

To prepare a set of yarn packages, two packages 1.1 and 1.2 are mounted on a package transfer adapter 2 with their hollow cores 1.3 and 1.4, the adapter being Flanges 2 and 2 for placing the hollow cores 1 and 4 of the lower yarn package on the lower end thereof
It is equipped with The adapter 2 has a head piece having a groove 2.1 l extending around its outer circumference for engaging the package gripper described below.
iece) 2 ・1 at its upper end. The headpiece 2.1 is provided on its inner side below its upper end with inwardly directed projections 2.12 for engaging coupling members of the elevated conveyor described below.

As seen in Figure 1, there are two packages 1.1 and 1.
A set 1 of thread packages consisting of 2 is pivoted together with an adapter 2 on hollow pins 3, 2 of a preparation device 3. The hollow pins 3.2 are rotatably supported on the base 3.1 of the preparation device 3 and are driven by a circular cord drive 3.3. The suction nozzles 3 and 4 can come into contact with the lower ends of the hollow pins 3 and 2. At the preparation station 3, the thread ends 1 and F2 are brushed away by brushes 3, 5, grabbed by suction devices 3, 6 and guided over the upper end of the hesod bead 2, 1.

The action of the suction nozzles 3 and 4 that come into contact with the lower ends of the hollow pins 3 and 2 is to suck the yarn ends into the package transfer adapter 2, as shown in FIG. It is maintained within the adapter during the entire duration of the transfer, as described above.

FIG. 2 shows the removal of the set 1 of yarn packages from the hollow pins 3, 2 of the preparation device 3 by means of the grisobar 4. To do so, the gripping members 4.1 of the package gripper 4 engage the grooves 2.11 of the adapter 2.

The pan cage center is held by a grill bar 4 and at the same time by a suspension holder, which forms part of the elevated conveyor system 5.

and F2 are additionally gripped onto the head 2.J by a cone 5.4 arranged on the package holder 5.2. The package holders 5.2 are advanced by rolls 5.3 along the transfer rails 5.1 of the conveyor system 5.

After engaging the set of yarn packages 1 with the holders 5, 2, the paso cage gripper 4 leaves the adapter 2.

FIG. 4 shows on the one hand a rail section 5.1 of a conveyor system 5 with an empty boppin holder 5.2 running along the rail, from which the gripper 4 has already removed the thread package set 1. is removed. The cough diagram also shows the second center 4' of the thread bar cage hanging from the holder 5, 2'.

The gripper 4, which engages with the arm 4.l on the hemlock piece 2.1, inserts the set 1 of thread packages removed from the holder 5.2 into the double-twist thread spindle 6.

As is known, the double-twisted yarn spindle has a whirl (w
hor 1: comprises a spindle groove wheel) 6.1, a rotating plate 6.2 with a thread storage disc and a protective pot 6.5 with a bottom 6.4, in which the pot is axially The adapter 2 is provided with hollow pins 6 and 3 arranged in the same direction, and an adapter 2 provided with a set 1 of yarn packages is mounted on the hollow pins. An injector (not shown) is disposed within the hollow pins 6 and 3, and the injector is connected to the yarn end F. and F2 are sucked into the spindle. Once the thread package cent held by the adapter is inserted, the package gripper 4 moves away from the adapter 2.

With reference to FIG. 5, the transport of a set 1 of yarn packages from a preparation location in a somewhat different embodiment of the conveyor system is depicted.

In this figure, the conveyor system 7 includes a guide track 7.1 along which a transfer plate 7.3 runs;
The plate supports hollow pins 7, 2 on its upper surface. For the movement of the plate along the track 7.1, the transport plate is driven on its underside by means of a circular code drive 7.4.

The advantage of the conveyor system 7 compared to an elevated conveyor is that it can be integrated into the transfer stream with a natural design of spacing. A conveyor system also means that the conveying flow is
This allows for a very simple switch structure, so that it can be reverted very quickly to the standby position, for example in the case of repeated operation.

For the transfer of the set 1 of packages, an adapter 2 is mounted on the hollow pins 7, 2 of the transfer plates 1, 7, 3.

The transfer plate moving along the track 7.1 is placed in a preparatory device 8 which includes a thousand steps 8.1 which slightly lift the transfer plate 7.3 and move it away from the circular code drive 7.4. enter.

A friction wheel arrangement 8.3 contacts the outer periphery of the transfer plate 7.3, thereby imparting rotation to the transfer plate. brush 8
