Abstract

PURPOSE: To distinguish cops which are different in quality and supplied in a mixed state at a slight cost by selecting the cops in a zone of exchange station between a ring fine spinning frame and a winder based on data. CONSTITUTION: Cops 4 being inserted into a bobbin carrier 5 in each selection are selected based on data related to different yarn qualities in an exchange station 3 laid between a ring fine spinning frame 1 and a winder 2. When the number of the cops sent to the exchange station is counted and the number of the cops 4 reaches a fixed number, preferably the boundary of two yarn qualities is confirmed and the cops are exchanged correspondingly.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a machine system consisting of at least one ring spinning frame and at least one winder, which are connected to each other via a converting station, in which a bobbin carrier in which a spindle is inserted can be used to improve the quality of the bobbin carrier. The present invention relates to a method and apparatus for sorting based on data related to.

Such a spinning frame control system is already known.As a spinning frame control system, a spinning frame control system in which a spinning frame is connected to a winder via a bobbin transfer path and an empty bobbin return path is already known (Germany). (see Federal Republic of Publication No. 3628 045). Identification symbols are provided on the transport means for the respective independent transport of the cops. Furthermore, a reading device for this identification symbol is used. This known structure serves to track the transport path of the spun yarn at each spinning station and to detect the corresponding yarn breakage information (this device is therefore intended to solve a very special problem). It is.

Furthermore, a yarn spinning position in a machine combination consisting of at least one ring spinning frame and at least one winder;
Methods for monitoring the quality of threads and bobbins also belong to the prior art. Federal Republic of Germany Patent Publication No. 37
12 654). In this method, the spindles formed in the ring spinning frame are fed in a predetermined order to a measuring device, a counting device, and a sorting device that are provided between the ring spinning frame and the automatic winder. This measuring device detects a quality characteristic and compares it with a comparison value. Tips that do not correspond to the comparison value are sorted out by a sorting device. This known method also serves to detect defective qualities.

It is also part of the prior art that the peg tray or bobbin carrier is provided with a quality-specific code for identifying the type of thread wound on the bobbin (German Published Patent Application No. 36 03 002 and (see DE 27 12 964).

The object of the invention is to provide a method and a device of the type mentioned at the outset, which makes it possible, with little outlay in mechanical engineering, to distinguish between chips of different quality and supplied in a mixed manner. It is to be.

This problem is solved according to the invention by sorting the bobbin carriers in which the tips are inserted in the area of the conversion station with data relating to the different thread qualities of the tips inserted in each case on the bobbin carrier. Ru.

This configuration results in a considerable mechanical engineering outlay, since the position of the coding is located in the conversion station between the ring spinning frame and the winder, in which case the spindle is treated and/or processed in any case. Reduced.

In this case, the concept of quality refers to the type of yarn (e.g. material, color,
fineness, twist) and yarn quality (e.g. fuzz, dirt) and cot quality (e.g. semi-gable kop, kop hardness)
It has

If combs of different yarn quality from one or more ring spinning machines are transferred through a converting station, the bobbin carriers must exhibit correspondingly different properties.

In this case, the following configurations are possible due to other features according to the invention.

Counting of the fed bobbin carriers and conversion of the sign of the total number of combs corresponding to the quality after a certain number of tips has been reached; one to the last bobbin carrier of the preceding quality or of the new quality at the boundary between different yarn qualities; Providing completely interchangeable elements on the bobbin carrier or on the tip transfer means; spinning of different yarn qualities on bobbin carriers of different colors and the use of sensors to identify the colors and replace the signs; to identify the different yarn qualities and to replace the signs; It is therefore advantageous to use a sensor which converts a color, for example for color identification or material identification or to carry out a fineness test, and at the same time to obtain a control element for maintaining the required quality.

As for the sign, it is not important whether the sign is used in a different manner or whether a certain sign is assigned to a variable thread quality; A sorting is carried out within the corresponding data relating to the different yarn qualities.

The invention will now be described in detail with reference to the embodiments illustrated in the accompanying drawings.

According to FIG. 1, a schematically illustrated ring spinning frame 1 is connected to a schematically illustrated winder 2 via a transfer system consisting of, for example, a transfer belt 8 and a beg-tray rail 18. A converting station 3 is provided between the ring spinning frame I and the winder 2 in the region of the interruption of the transport belt 8 and the beg-tray rail 18. This converting station 3 serves to extract the tip 4 inserted on the bobbin carrier 5 from the transfer belt 8 and transfer it onto the bag-tray-rail 18.

The bobbin carrier 5 is a tube bag in the area of the transfer belt and a bag tray in the area of the bag tray rail 18.

Sensing elements 6 and 7 are provided, placed in the area of the conversion station 3. This sensing element 6 reacts in this case to the passage of the tip 4.

This sensing element performs only counting, the counting pulses being fed via conductor 14 to a control device 12 where they are summed and the signs are replaced when a certain number sum is obtained.

Sensing element 7 requires switching element 9.19 for the above structure. This switching element 9 is in this case an actual switching element, such as a cam, a magnet, a reflector, and is especially provided on the transport belt. Sensing element 7 is designed accordingly.

The switching element 19 is the actual switching element that primarily belongs to the first tip of the new thread type and induces a change of sign.

However, this switching element 19 may also be a quality-related indicator on the tips, for example a constant color of the tube, a tube code or a thread color of each tip 4 of a new quality; the sensing element 7 then detects whether this It is configured so that it is possible to recognize colors or codes. In this embodiment, contrary to the arrangement described above, one quality arrives at the conversion station 3 in a crowd.

This is because this conversion station carries out the encoding accordingly for each tap. That is, in this case the switching element 19 does not mark a quality boundary, but rather marks a constant quality on the tip.

Sensors 10.11 are used as sensing elements 6.7, which are arranged at the entrance to the conversion station 3. The sensors 10, 11 are connected via conductors 14.17 to a control device 12, which itself has a code for identifying the bobbin carrier 5 in which the tip is inserted on the basis of quality-related data. It is connected to a converting device 13. As is clear from the drawings, the sensor 10,
11 is a coding device 13 in the population area of the bobbin carrier 5.
is provided in the exit area.

In this case, the sensor 10 is provided in the area of the comb 4 inserted into the bobbin carrier 5.

Alternatively to this configuration, it is also possible to provide a sensor 11 instead of this sensor 10 in the region of the transport belt 8 that transports the bobbin carrier 5.

The sensor can be designed as a sensing element for distinguishing between colors in the case of different qualities of comb on bobbin carriers of different colors, or as a sensing element for sensing material or fineness.

According to FIG. 2, a ring spinning machine 1 for spinning yarns of two different qualities A and B is connected via a converting station 3 to a winder 2.

By using the sensors mentioned in connection with FIG. 1 as sensing elements and switching elements in the area of the converting station, data relating to the different yarn qualities A and B and downstream of the converting station 3 are applied to the corresponding area of the winder. Identification is performed.

According to FIG. 3, two ring spinning machines 1 and 1' are used here as well, from which yarns of different qualities A and B are spun. Via the converting station 3, these different yarn qualities are applied to the winder after the corresponding sorting.

According to FIG. 4, a ring spinning frame l, in which yarns of different qualities A and B are spun, is connected via a converting station run 3 and a transfer system 16 to two winders 2 and 2'. Thanks to the cooperation of the above-mentioned elements, the bobbin carriers of the corresponding yarn products 1tA and B spun in the ring spinning frame 1 are provided in sorted form in the two winders 2 and 2''.

In the embodiment according to FIG. 5, four ring spinning machines 1.
1' bi° and 1''' are used, and these ring spinning machines spin yarns of different yarn qualities A, B, C. Again, a converting station 3 and switching and sensing elements separate these The data of the bobbin carriers in which the tips are inserted are identified for the different yarn qualities A, B, C. Via the transfer system 16' these bobbin carriers of different yarn qualities are transferred in the desired way to the three winders. 2.2', 2'', in which case, for example, winder 2 carries only the bobbin carriers for yarn quality, winder 2' carries the bobbin carriers for yarn articles IA and B, winder 2''
is given a bobbin carrier of yarn quality C and B. In this case, the transport system is provided with a circular transport path, on which the encoded bobbin carriers circulate until they are called up by one of the winders 2.2.2''.

What is common to the above systems is that one sensor and a switching element are used in the area of the conversion station. These sensors 10 , 11 are designed as light barriers or light scanners, which count the chips 4 passing by and provide a counting pulse to the control device 12 .

Here, after a certain number has been reached, the encoding device 13 is switched if, for example, one quality series has been passed and a cotup with another quality has arrived.

Alternatively, instead of sensor 10, it is also possible to use a sensor 11 which senses the markings placed at the two quality boundaries and which acts as switching element 9 and converts the sign in a defined manner. This marking can be provided, for example, on the transport belt 8 if the quality appears on the same transport belt 8, for example according to the embodiment shown in FIG. However, the indicator of the switching element can also be provided in the first and/or last tip 4 of the supplied quality series.

It is also possible to transfer the tip 4 by a transfer method other than standing it up on the peg of the transfer belt 8. For example, it is possible to transfer the tip 4 by placing it horizontally on the transfer belt 8 or by placing it on a peg-tray tray. It is also possible to transport it by inserting it on top. In this case, the cotsup can be transferred by the conversion station 3 to another transport means as a peg tray, for example onto another transport belt with a different peg pitch, and after corresponding treatment can be placed on the peg tray again. is also possible. In each case, the invention provides a bobbin carrier 5 in which the tip 4 is inserted with minimal mechanical outlay.
It is possible to identify data regarding its different qualities within the area of the conversion station 3 with respect to the data.
