(54) METHOD FOR SORTING SPINTUBES, COPS OR CONES (71) I, RUDOLPH ABRAHAM HUL SCHER, a Dutch citizen, of Drienerparkweg 3, Hengelo (0), the Netherlands, do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement: The present invention relates to a method of sorting spintubes, cops or cones.

Until now it has been customary to distinguish between yarn counts visually by observing the colour of the spintube. As a consequence of the continuing mechanization of the spinning and winding operations, visual recognition of tubes is no longer practical as cops are no longer positioned manually on the winding machine, but are dumped into a container, from where they are transported automatically to their positions on the winding machine. Furthermore there are more different yarn counts than there are spintubes which differ distinguishably. In this connection it should be observed that when a cop is full, only the extreme ends of the spintube are visible.

There is a risk that a different yarn count is present among a batch of cops with a certain count and this may result in considerable economic losses, since one wrong cop, usually containing some 3000 metres of yarn in one batch, may ruin one cone (or cheese) on which the yarn of usually 10 to 15 cops has been wound. In its turn one wrong cone, when used for weft, may ruin one or two metres of cloth and when used for warp may ruin even hundreds to thousands of metres of cloth.

According to the invention there is provided a method of sorting spintubes comprising the steps of guiding spintubes past a detection system; registering by physical means the presence or absence of detection rings arranged or positioned in a predetermined manner on the spintubes and transmitting signals indicative of the presence or absence of the detection rings so arranged or positioned; and ejecting spintubes not satisfying a required arrangement or positioning of selection rings.

The invention further provides a method of sorting cops comprising the steps of guiding cops with spintubes past a detection system; registering by physical means the presence or absence of detection rings arranged or positioned in a predetermined manner on the spintubes and transmitting signals indicative of the presence or absence of detection rings so arranged or positioned, and ejecting cops not satisfying a required arrangement or positioning of detection rings.

The invention also provides a method of sorting cones comprising the steps of guiding cones with spintubes past a detection system; registering by physical means the presence or absence of detection rings arranged or positioned in a predetermined manner on the spintubes and transmitting signals indicative of the presence or absence of the detection rings; and ejecting cones not satisfying a required arrangement or positioning of detection rings.

The method of the present invention can be carried out with an arrangement which is simple and cheap to construct, is easy to maintain and has a long operating life.

By using a distinctive spintube for each yarn count, every wrong cop can be recognized and removed. Different systems, suitable for measuring, for example changes in a magnetic field, changes in capacity, or the reflection or interruption of a signal of high frequency, as is further described hereinafter, may be used for detection. It is obvious that the choice of the materials used is dictated by the sensitivity of the detectors. In principle each variation of the homogeneity of the objects in the range of observation is measurable. Such a variation may be a reduction in or added amount of the material of the spintube at the measuring level, a different material. e.g., a metal, a non-metal, or a variation in the dimension of the material such as a thickening, thinning, or even an opening introduced at the detector level.By arranging the cops in a row and guiding them past the detection system, they can be recognized by their detection marks. Depending on the number of yarn counts to be distin guished from each other, the tube can be provided with a number of detection marks at different levels, corresponding with the levels of the different detectors. The recognition of the cops with the detection system is carried out in the same manner as for the spintubes. The system described above may also be used for cones, if this is required for practical reasons.

By way of example, a cop may have a spintube which has four detection marks.

With one position being used as a permanent position to ascertain the presence of a marked spintube, it is possible to distinguish between eight different yarns depending on positions on the marked spintube as well as the sequence thereof. It is obvious that by increasing the number of detection marks, the number of different possible combinations is increased, and thus any desired number of yarns may be distinguished by adding detection marks.

In the accompanying drawings: Figure 1 is a perspective view and shows cops moving with predetermined velocity along a detector bench, in accordance with the present invention; Figure 2 is a perspective view and shows the arrangement of a cop with detection rings; and Figure 3 is a perspective view and shows the arrangement of a cop provided with four detection rings in relation to a detection system.

Fig. I shows a detector bench 1, with cops moving by at a certain velocity, in this case with a velocity of 30 per minute. The cops 2 are guided past the detectors a, b, c and d.

The spintubes 3 are equipped with detection rings suitable for the particular detection system used at the level of the respective detectors. An appropriate energy source is mounted opposite the detectors a, h. c and d.

Depending on the coverage of the spintube. a signal will be received by the detectors. By pre-setting the detector bench in a particular pattern. e.g.. coverage of positions a. h, and d on the spintubes. deviating spintubes and cops can be ejected or in some way be removed from the system.

The cops 2 are as shown in Fig. 2. for example equipped with two detection rings a and d, or for example, as represented in Fig.

3 with four detection rings a. b, c and d A deviating spintube structure can be detected by various means. It can be done by changes in a magnetic field. changes in capacitance or reflection or interruption of a signal of high frequency. or other signals may be used.

When changes in the magnetic field or capacitance are to be measured. the detection ring usually consists of iron, copper or aluminium. but other metals or alloys which cause a change in the magnetic field or the capacitance may also be used.

Since wrong cops are ejected in some known manner when the above method is used, only cops with the proper yarn count will end up on the cones (or cheeses), the cones usually being wound simultaneously in large numbers. In this way material is not wasted unnecessarily by using a wrong cop in winding the cones, or by using a wrong cone or at least a partially faulty cone, for the production of cloth.

When using high-frequency signals for detection, the detection rings may consist of one of the above mentioned metals or another reflecting material.

The spintubes are provided with one or more detection rings, consisting of a modification of the nature and/or the thickness of the material of the tube. Suitable materials for the detection rings are, as mentioned earlier, metals such as iron, copper and aluminium, and non-metals such as glass or plastics. The detection ring may also consist of a greater or lesser amount of the material used in the spintube itself. The choice of the material of the detection rings depends of course on the chosen detection method; thus in the case of a magnetic field a suitable metal will be used, such as described above.

The cops 2 are as shown in Fig. 2. for example equipped with two detection rings a and d, or for example, as represented in Fig.

When changes in the magnetic field or capacitance are to be measured. the detection ring usually consists of iron, copper or aluminium. but other metals or alloys which cause a change in the magnetic field or the capacitance may also be used.

Since wrong cops are ejected in some known manner when the above method is used, only cops with the proper yarn count will end up on the cones (or cheeses), the cones usually being wound simultaneously in large numbers. In this way material is not wasted unnecessarily by using a wrong cop in winding the cones, or by using a wrong cone or at least a partially faulty cone, for the production of cloth.
