Abstract
Description
- The present invention relates to a washing machine for continuously running yarn or thread, and, more particularly, to a washing machine for continuously running yarn or thread comprising two bobbin spindles, which are mounted on a rotatable spindle below a projecting supporting arm extending from a machine housing and which can be alternately positioned between a winding position and a waiting position. Each spindle can support several bobbin sleeves. Several changing units are arranged next to each other in the supporting arm.
- This sort of washing machine for continuously running thread or yarn is described in EP 0 845 432 A1. An especially advantageous feature of this prior art machine is that the electronic unit or controller is not arranged, as usual in the prior art, in a separate control unit or panel behind the washing machine, but instead in the supporting arm which is arranged on the washing machine itself. The supporting arm has a U-shape in this machine, with its U-cross-section open upwardly, and the electronic unit is arranged between the upwardly extending sides of the supporting arm. It is provided with a cover and cooling ribs are provided on the top side of the cover. Because of the cooling ribs heat generated in the rectifier, which in operation provides the energy for the drive, is dissipated. However generation of an air flow over the cooling ribs or bodies is recommended to provide needed cooling during operation.
- It is an object of the present invention to provide an improved washing machine for continuously running yarn or thread, in which the cooling is improved in a special way without additional costs or efforts.
- According to the invention the washing machine for continuously running yarn or thread, comprises
- a machine housing;
- a supporting arm projecting from an upper portion of the machine housing, said supporting arm comprising at least one changing unit;
- a contacting roller;
- at least one bobbin spindle for holding at least one bobbin sleeve, according to a total number of the changing units present;
- drive motors for the at least one bobbin spindle, the contacting roller and the at least one changing unit; and
- an electronic unit comprising a rectifier for supplying the drive motors with electrical energy and means for controlling the drive motors;
- wherein the electronic unit is arranged on the same side of the machine housing as the supporting arm, the contacting roller and the at least one bobbin sleeve; and the electronic unit is arranged below the supporting arm.
- The washing machine according to the invention has a structure that enables the required air flow for cooling the electronic unit or device to be supplied during operation by the rapidly rotating bobbins.
- Various preferred embodiments provide additional advantages.
- In a preferred embodiment the electronic unit is accommodated in a flat control housing having a side facing the bobbin spindle or spindles and the control housing is provided with cooling ribs on a side facing the spindle or spindles. In an especially preferred embodiment the control housing accommodating the electronic unit is flat and arranged in the vicinity of supporting members or feet of the washing machine and cooling ribs are oriented transversely to an axis of the contacting roller. In another especially preferred embodiment the control housing accommodating the electronic unit is flat, rests on one of its small edges and extends on a long side of the washing machine and the cooling ribs are vertically oriented. In both especially preferred embodiments the control housing is spaced from the bobbin spindles or bobbins with the cooling ribs facing them, so that a sufficient air flow for cooling is provided during operation.
- The objects, features and advantages of the invention will now be illustrated in more detail with the aid of the following description of the preferred embodiments, with reference to the accompanying figures in which:
- FIG. 1 is a schematic partially cutaway, front view of a first embodiment of a washing machine according to the invention;
- FIG. 2 is a perspective view of the washing machine shown in FIG. 1;
- FIG. 3 is a schematic front view of a second embodiment of a washing machine according to the invention; and
- FIG. 4 is a perspective view of the washing machine shown in FIG. 3.
- A machine housing1 rests on two stand or supporting
members damping elements 4 on their bottom ends. A disk-like bobbin support 5 is rotatably mounted so as to be rotatable about a horizontal axis. Two projectingspindles spindle 6, which is shown above theother spindle 7 in the drawing. Two finishedwound bobbins other spindle 7, already ready for removal and transport. - A projecting supporting
arm 12, whose cross-section extends almost over the entire width of themachine housing 1, is attached to themachine housing 1 above thebobbin support 5. A contactingroller 13, which extends parallel to thespindles units 14 associated with theindividual spindle sleeves arm 12 above the contactingroller 13. Each changingunit 14 is equipped with two rotors driven in opposite rotational directions, which each have two or three propeller-like vanes or blades. These changing units, the so-called blade changers, are described in EP 0 771 302 B1. Respectivecurved slots units 14 in a cover of the supportingarm 12 for each of the corresponding yarns or threads. The cover is provided with a common guidingbracket 17, which extends over an entire length of thespindles panel 18 is provided on the free end of the supportingarm 12, which provides controls for the operating personnel for control of the machine. - The
spindles contacting rollers 13 and the changingunits 14 are provided with drive motors DM, which are shown only diagrammatically in the drawing. The different drive motors DM are coupled with each other in a known manner. A flat box-shaped control housing 19 is arranged at a short distance under the region described in more detail hereinbelow, which is reserved for the bobbin structure and for the motion of the bobbins according to the rotational motion of thespindle support 5. It essentially fills the entire free area between both standmembers spindles 6,7 (that is also true for thestand member 2 which is shown cutaway in the drawing to improve the clarity of the illustration). The height of thecontroller housing 19 is small in comparison to its dimensions in the transverse and longitudinal direction, so that it has approximately the form of a plate. Its upper side is provided withcooling ribs 20, which extend transversely.Damping elements 21 are provided on its lower side. It is supported on the ground independently of themachine housing 1. An electronic unit or device EU, which especially includes a rectifier R for supplying the drive motors with electrical energy, is accommodated in the interior of thecontroller housing 19. The electronic unit or device EU in thecontroller housing 19 also includes electronic means for control of machine operation and for signal transmission. The electronic device EU unit is connected with the drive motors, with the operator'spanel 18, with unshown sensors and with an external control system by means of a plug strip and by means of an unshown cable. - In operation, bobbins are wound on the
spindle sleeves spindle 6 in a winding position. Accordingly thebobbin support 5 is rotated —as already described for example in EP 770 030 B1—in the direction of thearrow 23 according to the increasing diameter of the bobbins, so that the bobbins in the structure are continuously under a gentle pressure from the spatially fixed contactingroller 13. If thespindle 6 is in theposition 24 shown with dashed lines, thenew bobbin 25 has reached the predetermined diameter. The bobbin orspindle support 5 now quickly rotates further, until thespindle 7, which in the meantime is provided with a fresh spindle sleeve after withdrawal of the finishedbobbins roller 13 in the position in which thespindle 6 is shown in FIG. 1. During this rotation thebobbin 25 passes through a spatial region which extends up to asleeve surface 26. - A powerful air flow is produced by the rotating bobbins present in the structure which rotate at a high rotation speed, for example 2000 m/sec, which sweeps or brushes over the top side of the
controller housing 19 provided with thecooling ribs 20 in the direction in which thecooling ribs 20 extend. Because of this feature the heat, which is produced by the electronic components, especially by the rectifier for the drive motor, is effectively dissipated. A failure of the cooling during the winding operation is thus prevented. Because of the independent mounting of thecontroller housing 19 vibrations of the machine are not transferred or transmitted to the control housing and the electronic components in it. The dampingelements - The embodiment illustrated in FIGS. 3 and 4 differs from the above-described embodiment, because the
control housing 19 is arranged beside the spatial region, which is reserved for the bobbin structure and the motion of the bobbins according to the rotation of thespindle support 5. The control housing of course extends on the long side of the spindles which is opposite to the long side on which the contactingroller 13 contacts. Thecontrol housing 19 stands on its small or narrow edge on thestand member 3 and extends upward until its upper edge nearly reaches the supportingarm 12. Dampingelements control housing 19 and thestand member 3 and/or the supportingarm 12. Theribs 20 are formed on the side which is facing the sleeve surfaces 26, and extend vertically. The spacing of theribs 20 from the sleeve surfaces 26 is large enough so that thefull bobbin 25 remains unhindered in its motion. - The operation of the second embodiment is similar to that of the first embodiments and so further description of the operation is dispensed with.
- The disclosure in German Patent Application 195 45 823.5-26 of Sep. 24, 1999 is incorporated here by reference. This German Patent Application describes the invention described hereinabove and claimed in the claims appended hereinbelow and provides the basis for a claim of priority for the instant invention under 35 U.S.C. 119.
- While the invention has been illustrated and described as embodied in a washing machine for continuously running yarn, it is not intended to be limited to the details shown, since various modifications and changes may be made without departing in any way from the spirit of the present invention.
- Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
