Abstract

PCT No. PCT/CH90/00288 Sec. 371 Date Aug. 2, 1991 Sec. 102(e) Date Aug. 2, 1991 PCT Filed Dec. 20, 1990 PCT Pub. No. WO91/10001 PCT Pub. Date Jul. 11, 1991.An apparatus for steaming of spun cops based on a trough-shaped steamer (2) arranged directly adjacent to a spinning machine (1) parallel to the cops (15) of a spinning station (14) standing in a row. This enables a conventional handling device (17) to move the cops (15) from the spinning stations (14) into the steamer (2) and, after the steaming process, to move the cops (15") from the steamer (2) to the conveyor (16) of the spinning machine (1). The steaming process is thus integrated with the material flow of the spinning plant. The dwell times of the cops after steaming are largely predeterminable. Also, the space requirements of the equipment are minimal and there is no need for additional manual moving of the cops.

Description

• eine Spinnmaschine mit mehreren in einer Reihe angeordneten Spinnstellen auf denen Kopse erzeugt werden, die je eine Hülse enthalten
• einen Förderer zum Abtransport der fertig gesponnenen Kopse;
• eine Abzugsvorrichtung zum Zubringen von leeren Hülsen zur Spinnmaschine und zum Abnehmen der Kopse von der Spinnmaschine und zum Aufsetzen der Kopse auf den Förderer
• einen Dämpfbehälter zur Wärmebehandlung und/oder Befeuchtung der fertig gesponnenen Kopse.

The invention relates to a method for shortening the transport routes in the heat treatment and / or moistening of cops spun on sleeves at several spinning positions of a spinning machine in a steaming container. Furthermore, the invention relates to a device for spinning, for heat treatment and / or for moistening threads, comprising:

• a spinning machine with several spinning stations arranged in a row on which cops are produced, each containing a sleeve
• a conveyor for removing the finished spun cops;
• a take-off device for feeding empty sleeves to the spinning machine and for removing the cops from the spinning machine and for placing the cops on the conveyor
• a steaming container for heat treatment and / or moistening the finished spun cops.

In a known method and a known device of this type (FR -A- 2620743, EP -A- 2620743 and EP -A- 2614633) the steaming container is located between the spinning machine and the winding machine. The finished spun cops are transported from the spinning machine into the steaming container by a conveyor belt. The finished steamed cops are then transported from the steaming container to the winding machine by a second conveyor belt. The finished spun cops must be brought from the spinning machine onto the first conveyor belt by means of a take-off device. In addition, a second conveyor belt is required between the steam container and the winder. Thus, two conveyor belts are required in the known devices, which are very needed a lot of space. There is also the danger that material confusion (the cops) will occur in the known method.

• a) Ein Verfahren zur Wärmebehandlung und/oder Befeuchtung von Kopsen zu schaffen, welches mit möglichst geringem Aufwand durchgeführt werden kann und möglichst wenig zusätzlichen Platz beanspruchende Aenderungen an der Einrichtung zur Durchführung des Verfahrens erfordert.
• b) Es soll eine Einrichtung geschaffen werden, die auf möglichst platzsparende und einfache Weise eine Wärmebehandlung und/oder Befeuchtung von Kopsen ermöglicht.

The invention is based on two tasks:

• a) To create a method for heat treatment and / or moistening cops, which can be carried out with the least possible effort and requires as little additional space-consuming changes to the device for performing the method.
• b) A facility is to be created which enables heat treatment and / or humidification of cops in the most space-saving and simple manner possible.

The first-mentioned object is achieved according to the invention in that each cop is subjected to heat treatment and / or moistening directly at the spinning station of the spinning machine in order to avoid long transport routes between the spinning machine and the steaming container. - The term "spinning station" used in the claim means the space required for spinning around the cop to be produced - for balloon formation.

With this procedure, the heat treatment and / or moistening of the cops takes place in the immediate vicinity of the spinning positions of the spinning machine and a conveyor belt between the spinning machine and the steaming container is no longer required. A particular advantage is the largely freely definable dwell time during and after steaming. Therefore, the cops no longer need to be removed from the material flow path. The method according to the invention can be carried out more quickly than the previously known method and eliminates material blurring. Furthermore, a lot of space is saved compared to the known spinning systems with a steam container placed at a distance. The steaming container is designed as a closable, open channel in the manner of an elongated trough.

The second task, namely the creation of a device for carrying out, is achieved according to the invention in that the steaming container has a number of steaming points and is set up parallel to the spinning machine in such a way that there is a steaming point at each spinning point, and the take-off device for each spinning point has a gripping device has, which takes the finished spun cops from the spinning station and inserted into the adjacent steaming point of the steaming container.

As a result of this design and arrangement of the steaming container, very little space is required for the steaming container in the spinning system. Furthermore, the workflow is optimal because the cops only have to travel very short distances for heat treatment and / or moistening.

Further developments of the subject matter of the invention are characterized in the following dependent claims.

The method steps mentioned in claim 2 enable the use of a take-off device which is required anyway in spinning machines and which, with slight changes in adaptation, use to remove the cops from the spinning station and to insert them into the steaming container, to take the steamed cops out of the steaming container and to place them on the conveyor , which transports the cops to the winding machine.

The method steps mentioned in claim 3 allow optimal utilization of the treatment and cycle times.

The process control according to claim 4 has proven particularly useful.

A further development of this method is given by the evacuation drying according to claim 5.

The sequential material flow (handling) is preferably carried out according to the method of claim 6.

In the claims 7 to 10, intermediate storage options of one batch during the steaming treatment of a second are listed, which are to be selected depending on the configuration of the spinning machine and / or its take-off device and conveyor.

Depending on how the take-off device is designed and what space is available in front of the spinning machine, it may be advantageous if the steam container on the side facing away from the spinning machine of a conveyor leading to the winding machine or if it is between the spinning machine and a arranged in front of it to the winding machine leading conveyor and / or the extraction device is arranged (claims 12 to 14).

The entry of steam into the steaming container can be interrupted in a simple manner by blocking off steam access openings, by means of two mutually displaceable perforated plates.

The amount of water is also controlled in a simple manner according to claim 16.

To transport the cops, a horizontally and vertically movable conveying device can be provided instead of the usual extraction device or instead of a redesigned extraction device above the steaming container. Such a conveying device can be designed, for example, like a conventional loading device of a lathe as a portal loader, cf. Claim 17.

In the open state, the lid of the steaming container does not hinder the transport of the cops into the steaming container or from the steaming container to the conveyor by means of the pull-off device if the steaming container has a lid hinged to the side of the steaming container facing the spinning positions, according to claim 18.

It is structurally particularly simple if the lid, according to claim 19, by means of a on the side wall and a cantilever arm of the cover attached lifting cylinder is operable.

Adaptation of the steaming container to spinning machines of different sizes is possible with little effort if the steaming container is modularly composed of a plurality of elements arranged one behind the other and forming the channel-shaped steaming container (claim 20).

The individual elements are optimally designed according to the further advantageous development according to claim 21.

In the simplest case, the heating element consists of an electrical resistance heater; it can also be a heat exchanger of a steam heating system, which is particularly advantageous in the case of existing heat recovery systems in the spinning mill.

The system is autonomous according to claim 22 by an external steam generator, which can be arranged as desired.

The embodiment according to claim 23 is a cheaper device; in addition to screwing the steam container directly onto the machine frame, it also shows its flanges.

There can be an additional gain in space if the steaming container, according to claim 24, is arranged above the spinning machine. Draw-off devices arranged in the upper region of the spinning machine are known, in particular as so-called stationary, integrated automatic take-off devices in ring spinning machines. - With simple design adjustments, this type of extraction device can be used to move the cops into the steaming container arranged above the machine.

• ein weiterer Antrieb zum Öffnen und Schliessen des Dämpfbehälters.

The following elements are contained in the end element 6 of the damper:

• a fan
• further heating elements and
• another drive for opening and closing the steam container.

Since the damper 2 differs only slightly from known dampers of this type, not all of the organs mentioned above are described in detail.

• a) Wassertemperatur bzw. Dämpfraumtemperatur
• b) Wasser- bzw. Dampfdruck
• c) Wasser-Niveau
• d) Wasserabdeckung
• e) Ventilation des Dampfbehälters

1, the vacuum unit 8 and the electrical cabinet 9 are located at one end of the spinning machine 1, which are also assumed to be known here and are not described. Depending on the size of the damper 2, the vacuum unit 8 has one or more vacuum pumps, which are likewise not shown and described in more detail. In the electrical cabinet 9 there are electrical current distributors, in particular contactors for the motors and for the heating elements, which are also assumed to be known and are not described in more detail. The control cabinet 10 contains all the elements necessary for controlling and monitoring the following data:

• a) Water temperature or steam room temperature
• b) water or steam pressure
• c) water level
• d) water coverage
• e) ventilation of the steam container

3 and 5, the damper 2 extends over the entire length of the spinning machine 1 and has exactly as many damping points 2b as the spinning machine 1 has spinning points 14.

All of these control and monitoring elements are assumed to be known and are therefore neither shown nor described.

2, two spinning machines 1 are set up side by side. There is a damper 2 on each side of these spinning machines 1. A control cabinet 10 is provided for each damper 2.

According to FIGS. 3 and 4, a cop 15 is located at each spinning station 14. According to FIG. 3, the spinning machine 1 has a long row of spinning stations 14 between the two control boxes 1a and 1b, all of which are provided with cops 15. In front of this row of spinning stations 14 there is a conveyor 16 which is arranged somewhat lower than the spinning stations 14.

• 1) Die leeren Hülsen 15a sollen den Spinnstellen 14 zugeführt werden
• 2) Die fertigen Kopse 15 sollen einer Spulmaschine 12 (Fig. 1) zugeführt werden

This conveyor 16 has two main functions

• 1) The empty tubes 15a are to be fed to the spinning stations 14
• 2) The finished cops 15 are to be fed to a winding machine 12 (FIG. 1)

For this purpose, the conveyor 16 extends over the whole Length of the spinning machine 1 and has as many pick-up points as there are 1 spinning points 14 on the spinning machine. In front of this conveyor 16 is the damper 2, which in turn extends over the entire length of the spinning machine 1 and has as many receiving points as the spinning machine 1 has spinning stations.

3 and 4, the take-off device 17 is articulated on two beams 40, which are located on top of the spinning machine 1. 4, an axis 41 is slidably mounted on this beam 40. With the help of an actuating cylinder 42, the axis 41 can be shifted from its foremost position shown in solid lines to the rear dash-dotted positions.

• a) oberhalb der Spinnstellen 14
• b) oberhalb des Förderers 16
• c) oberhalb des Dämpfers 2

The piston 43 in the cylinder 42 is displaced pneumatically or hydraulically in the usual way. According to FIG. 3, two rods 45 are pivotably articulated on this axis 41 (FIG. 4). At the lower end of these rods 45 two further rods 46 are articulated. At the lower end of the bars 46, a coping removal bar 47 is fastened. This cops removal bar 47 extends over the entire length of the spinning machine 1 and has a gripper 48 (FIG. 4) for gripping a cop for each spinning station 14 of the spinning machine 1. This gripper 48 is shown in FIG. 4 and described in detail below. To raise and lower the copse removal bar 47, a roller 50 is mounted on each bar 40, on which a band 51 is wound, which is fastened at its lower end 49 to the copse removal bar 47. According to FIG. 3, the strips 47 can be used to lower the bar 47 from an uppermost position shown in solid lines to a lower position shown in dash-dotted lines, the rods 45 and 46 also pivoting into the dash-dotted positions. With a motor 52, the roller 50 can be rotated in both directions of rotation for winding and unwinding the tape 51. 4, the removal bar 47 must also the grippers 48 are brought into three different positions, namely

• a) above the spinning stations 14
• b) above the conveyor 16
• c) above the damper 2

Thus, the piston 43 must also move into three different positions and the band 51 must be able to be lowered accordingly to three different heights. 4, the damper 2, with a damping container 2a, which is rectangular in cross section, is lower than the conveyor. On its side wall 18 of the damper 2 facing the spinning machine 1 or the conveyor 16, a cover 7 is articulated on a hinge 19 of the damper 2. The cover 7 has a cantilever arm 20, on which a lifting cylinder 21 engages, the lower end of which is articulated on a projection 22 of the side wall 18. A piston 21 'in the lifting cylinder 21 is articulated via a piston rod 21' on the extension arm 20.

Moves the piston 21 'down with the piston rod 21˝, the lid 7 is opened.

3 and 4 there are a number of cops 15 above a water bath 24 in the interior of the steaming container 2. This water bath 24 has a water bath cover 23 on which the cops 15 are held at the steaming points. The water bath 24 can be heated cyclically by heating elements 25.

In the spinning system according to the invention, the following material flow results: As soon as a row of cops 15 has been spun, the automatic take-off device 17 moves to the left, as seen in FIG. This sequence of movements is indicated in Fig. 4 by the two arrows a and b. If the cops 15˝ in the steaming container 2, its cover 7 is closed by means of the lifting cylinder 21 and the steaming process can begin. While of the steaming process, the take-off device 17 fetches empty spinning tubes (not shown in FIG. 4) from the conveyor 16 and places them on the spinning stations 14. This is indicated by an arrow c. The next batch of cops 15 can then be spun. When the steaming process in the steaming container 2a has ended, the cops 15˝ are pulled out of the steaming container 2a by the extraction device 17 after opening the cover 7 and placed on the conveyor 16. This movement is indicated by the arrow d. The conveyor 16 then transports the cops 15 'to the winding machine 12 (Fig. 1). This cycle is repeated in that the take-off device 17 again inserts completely spun cops 15 into the steaming container 2a.

5, the damper 2 is located between the spinning machine 1 and the conveyor 16. The extraction device 17 is arranged on the side of the conveyor 16 facing away from the spinning machine 1.

5 and 6 there is a spindle 53 in front of the conveyor 16 at the bottom, which extends over the entire length of the spinning machine 1. On this spindle 53 two slides 54 are slidably mounted. A rod 55 is pivotably articulated on each of these slides 54. A second rod 56 is articulated on the one hand at a location 57 (FIG. 5) and, on the other hand, is articulated in the vicinity of the upper end of the rod 55. A rops removal bar 58 is in turn articulated at the upper end of the two rods 55. This Kops removal bar 58 extends over the entire length of the spinning machine 1 and has a gripper 48 for each spinning station 14 of the spinning machine 1, just like the removal bar 47 described above. This gripper 48 is shown in FIG. 4 and is described in more detail below described. The spindle 53 is rotated to raise and lower the coping removal bar 58. As a result, the carriage 54 moves to the position 54 'and the two rods 55 and 56 are moved into the position shown in dashed lines of the rods 55' and 56 '. By pivoting the rods 55 and 56 in the position 55 'and 56', the Ropsen removal bar 58th moved from its lower position to the upper position, which is designated by number 58 '. 6, the two rods 55 and 56 can still be pivoted about the spindle axis 53, as indicated by the arrow B. As a result, the cop removal strip 58 can not only be raised and lowered, but also pivoted to the left and right.

• a) Die Abzugsvorrichtung wird zum Erfassen der Kopse 15 nach links verschwenkt, Pfeil a.
• b) Die Kopse 15 werden von der Spinnstelle 14 in den Dämpfbehälter 2a gebracht, Pfeil b.
• c) Die gedämpften Kopse 15 werden aus dem Dämpfbehälter 2a zum Förderer 16 gebracht, Pfeil d.
• d) Leere Hülsen werden vom Förderer 16 zu den Spinnstellen 14 der Spinnmaschine 1 gebracht, Pfeil c.

To pivot the spindle axis 53, a cylinder 61 is pivotably articulated on a holder 62 on the base 60 according to FIG. 7. In this cylinder 61 there is a piston 63 which is connected via a piston rod 64 to a swivel arm 65 which is fastened to the spindle 53. By moving the piston 63 in the cylinder 61, the spindle 53 can thus be rotated and thus the rods 55 and 56 can also be pivoted, as indicated by the arrow B in FIGS. 6 and 7. As in the first exemplary embodiment (according to FIGS. 3 and 4), the coping removal bar 58 of the second exemplary embodiment according to FIGS. 5, 6 and 7 must be moved into three different positions. These movements are as follows:

• a) The trigger device is pivoted to the left to grasp the cops 15, arrow a.
• b) The cops 15 are brought from the spinning station 14 into the steaming container 2a, arrow b.
• c) The steamed heads 15 are brought from the steaming tank 2a to the conveyor 16, arrow d.
• d) Empty tubes are brought from the conveyor 16 to the spinning positions 14 of the spinning machine 1, arrow c.

6 and 7, the same trigger device 17 is used. 6, however, the damper 2 is located between the conveyor 16 and the spinning machine 1. In FIG. 7, however, the conveyor 16 is located between the damper 2 and the spinning machine 1.

8, a spindle 70 can be driven by a motor 71 in both directions of rotation, as indicated by a double arrow 72. Two slides 73 are located on this spindle 70 and 74 slidably guided. One carriage 73 is shifted by a right-hand thread 75 and the other carriage 74 by a left-hand thread 76, such that when the spindle 70 is rotated by the motor 71, the two carriages 73 and 74 move against one another when the spindle 70 is in a direction of rotation is rotated or moved away from each other when the spindle 70 is moved in the other direction. A scissor-type linkage 77, 78, 79, 80 is articulated on the two slides. On the rods 77 and 78 of this linkage 77 to 80, an already mentioned cop removal bar 81 is articulated, which, like the cop removal bars 47 and 58 described above, extends over the entire length of the spinning machine 1. This cop removal bar 81 is raised and lowered by several rods 77 to 80. In Fig. 8, however, only a single linkage 77 to 80 is shown. Likewise, the spindle 70 extends over the entire length of the spinning machine 1 and serves to drive all the linkages 77 to 80. A cylinder 82 which contains a piston 83 is used to pivot the linkage 77 to 80 with the cop removal bar 81. This piston 83 is articulated on a plate 85 via a piston rod 84. This plate 85 is attached to the carriage 74. With the aid of the cylinder 82, the plate 85 with the slide 74 and the linkage 77 to 80 can thus be pivoted into three different positions. These different positions are indicated by dash-dotted lines of the plate 85 and the cop removal bar 81. Grippers 48 (see FIG. 21), which are described below, are fastened to this cop removal bar 81 for gripping the cops 15. The cylinder 82 is articulated on a carrier 86 which can be displaced parallel to the spindle 70. The spindle 70 is supported on a plurality of bases 88. Only a base 88 is visible in FIG. 8. The device according to FIG. 9 differs from the device shown in FIG. 8 essentially in that the two slides 73 and 74 are not pivotable with the linkage 77 to 80. The linkage 77 to 80 instead raises and lowers a plate 87 when the spindle 70 rotates in one direction or the other turns. A scissor-like linkage 89 and 90 is also articulated on this plate 87. The cop removal bar 81 already mentioned is articulated to the rod 89. A cylinder 92, which contains a piston 93, is used to move the cop removal bar 81 in the horizontal direction according to arrow 91. This piston 93 is articulated via a piston rod 94 on the rod 89 of the linkage 89 and 90. The cylinder 92 is in turn articulated on the cop removal bar 81. With the help of the spindle 70, the plate 87 can thus be raised and lowered in the direction of the arrow 92 'and, with the aid of the cylinder 92, the cop removal bar 81 can be moved in the horizontal direction. So that the scissor-like linkage 89, 90 can be opened and closed, the rod 90 of the linkage 89, 90 is slidably mounted in a slot 87 'with one end in the plate 87.

According to FIG. 10, the steaming tank 2a is located above a water channel 26 with a circular cross-section. From this water channel 26, a riser 27 leads upwards into the water bath space 24 of the steaming tank 2. A shut-off valve 28 serves to be able to open or close the riser 27. The water bath cover 23 in turn serves to support the cops 15 ′ introduced into the steaming container 2. 10 also shows a cable channel 29 running parallel to the water channel 26 and in which electrical lines 30 run; likewise sealing elements 2 'in the area of the cover 7.

According to FIG. 10 there is an arm 106 on the steaming container 2a, on which there is a conical mandrel 107. This mandrel 107 serves to center the cop removal bar 47, FIG. 3, or 58, FIG. 5, or 81, FIGS. 8 and 9.

In the embodiment according to FIG. 11, the water bath space 24 is covered by two perforated plates 33, 34 lying one above the other. The lower perforated plate 33 is firmly connected to the walls of the steaming container 2. The upper perforated plate 34 can be moved in the longitudinal direction on the lower perforated plate 33. Thereby it is possible to shut off the water bath space 24 from the rest of the interior of the steaming container 2. The water bath cover 23 also serves here as a support for the cops.

12, the damper 2 extends over the entire length of the spinning machine 1 and is composed of several intermediate elements 3, 4 and 5. Since this damper 2 is exposed to large temperature fluctuations, means must be available so that these intermediate elements 3, 4 and 5 can expand and contract unhindered. Two embodiments of such means are shown in FIGS. 13 and 14.

13, an O-ring is provided as a sealing ring 95 at the end of the one intermediate element 3, which lies against the inner wall 96 of the other intermediate element 4. If the two intermediate elements 3 and 4 expand or contract, the sealing ring 95 can slide on the outer wall 97 of the intermediate element 3. The inner wall 96 surrounds the sealing ring 95 in the form of an annular groove.

According to FIG. 14, a tubular, dilatable seal 100 is present between an end wall 98 of one intermediate element 4 and an end wall 99 of the other intermediate element 3, which seal can be compressed when the two intermediate elements 3 and 4 of the damper 2 are thermally stretched.

15, a telescopic rod 101 is rotatably mounted about a pivot axis 102. This telescopic rod 101 is composed of three tubular sections which have different diameters so that they can be pushed into one another. A cop removal strip 104 is fastened to this rod 101 via a carrier 103. The grippers 48 described below with reference to FIG. 21 are fastened to this cop removal bar 104, with which the cops 15 can be transported from the spinning machine 1 to the steaming container 2. The conical mandrel 107, which projects into a bore 105 of the carrier 103, is fastened to the steaming container 2 via the arm 106. This ensures that the cops 15 are pushed exactly into the steaming container 2.

16 shows that a plurality of risers 27, 27a, 27b lead from the water channel 26 to the steaming container 2. The water channel 26 receives water from an expansion tank 31 by means of pumps 32. A flow meter 34 'is able to detect the amount of water delivered. Controlled throttle valves 32 ', 33' control the inlet speed of the water; a level monitor 31 'regulates the water level in the tank 31st

The vacuum system of a complete plant is shown in Fig. 17. A vacuum pump 35 constantly evacuates a vacuum vessel 36, to which a vacuum line 37 is connected, from which lines 39 each lead via a valve 38 to the individual steaming containers 2. The negative pressure in the respective steaming container 2 can therefore be controlled by the respective valve 38.

The treatment process is divided into a treatment time t _B and a drying time t _T. The diagram clearly shows how the negative pressure diminishes during the heating-up times. After heating up twice, the temperature and, accordingly, the pressure are kept constant over a longer period of time. To dry, the steaming container is ventilated several times, heated, placed under vacuum and ventilated again. It means:

The characteristic temporal material flow when steaming cops can be seen in FIG. 20. The actions are entered in the ordinate and the time intervals in the abscissa t in hours h.

It means:

The intervals between the spiders D that are not entered are the operating times of the take-off device.

When the cops are temporarily stored, this extraction device is activated, i.e. after the steaming process has ended and after the first batch has been made available. ready to hand over the stored cops.

The basic process control, the choice of vapor pressure, the temperatures and the addition of any chemicals are known in particular for yarn steaming. See Freddy Wanger, man-made fibers / textile industry vol. 30/82, 1980, pp. 888-890; Melliand Textile Reports 66, 1985, pp. 525-526; Textile company, Vogel-Verlag Würzburg, 1981, issue 7/8. The subject of the invention can be adapted to all desired process and operating conditions.

Of course, the term "heat treatment" used in the claim also includes sterilization processes, such as those used in the manufacture of hygiene articles, dressings, compresses, etc.

According to FIG. 21, a compressed air tube 68 is fastened to the cops removal bar 47. A number of grippers 48 are fastened to this compressed air tube 68 and serve, as described above, for gripping cops 15. These cops 15 contain a sleeve 15a. On the spinning machine 1, the thread is spun into a cop 15 on the sleeves 15a. The gripper 48 has a nozzle 69 to which a small inflatable rubber balloon 67 is attached with the aid of a strap 66. If there is no compressed air in the compressed air tube 68, this balloon 67 has the shape shown in broken lines. Once in the tube 68 compressed air is fed in, this balloon inflates until it rests against the inner wall of the sleeve 15a and holds it in place, as indicated by the solid lines.

Alternatively, the cops can be gripped peripherally, in the manner of a collet.

To reduce the size of the steaming container, the cops could be pushed together for the heat treatment and / or moistening. For this purpose, known means or handling devices are available. The embodiment according to FIG. 21 can be adapted to this requirement by using telescopically or elastically designed strips 47.
