DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device for heat treatment and/or humidification of spools, cops and cones, in which an elongated, evacuatable steaming vessel is provided.
In spinning mills it has been a long-known practice to steam yarns. Particularly useful were found to be steaming vessels in which the cops were arranged above a heated water bath in a saturated-steam atmosphere. For this purpose, the cops must be removed from the spinning machine, treated in the steaming vessel and then moved to the winding machine. In the known devices, this necessitated a special transport system which required a great deal of space. In addition, the system increased the risk of material mix-up.
It is the object of the invention to provide a device for heat treatment and/or humidification of cops which involves as low an expenditure as possible and requires as little additional space as possible and which furthermore facilitates optimal integration of the material flow into the production process and minimizes the required conveying paths.
This object is achieved in that the steaming vessel is configured to be conduit-shaped and height-adjustable, or that the steaming vessel is in the form of an enclosed conduit open at both its end faces, and that these end faces are contiguous with at least one conveyor.
Both embodiments of the invention facilitate the adapting of the heat treatment process to textile machinery and to integrate this process into the material flow.
The subsequent dependent claims characterize further advantageous developments of the object of the invention.
Entrance of steam into the steaming vessel can be interrupted by shutting off the steam access openings in a simple manner by two perforated sheet-metal strips slidable one relative to the other, claim 3.
Control of the water quantities is effected in an equally simple way according to claim 4.
In its opened state, the lid of the steaming vessel will not interfere with the movement of the cops into the steaming vessel or from the steaming vessel to the conveyor, if the steaming vessel is provided with a lid articulated by means of a hinge to that lateral wall of the steaming vessel that faces the spinning stations, as claimed in claim 5.
A particularly simple design is achieved if, according to claim 6, the lid is configured to be actuatable by means of a lifting cylinder attached to the lateral wall and to a cantilever arm of the lid.
In order to reduce mass with a height-adjustable steaming vessel, a design according to claim 7 is recommended, in which the lid is slid closed and open via a horizontal cantilever arm.
The steaming vessel can be adapted to machinery of differing dimensions at low costs if the steaming vessel is modularly assembled from several elements which, assembled one after the other, form in their totality the conduit-like steaming vessel (claim 8).
The separate elements can be optimally designed according to the further advantageous development as recited in claim 9.
According to claim 10, the steaming conduit is rendered autonomous and particularly light-weight by an external steam generator which can be arranged according to choice.
A design according to claim 11 reduces heat losses in the steaming vessel.
By a design according to claim 12, it is possible to produce a vacuum also in steaming vessels having open ends. According to charge sizes and cycle times, this makes it also possible to optimize process flow.
Particularly simple are conveyors with guide rails accommodating sliding bodies according to claim 13.
The separate zones or chamber segments in the steaming vessel are preferably supplied as claimed in claim 14.
The arrangement, in the closable steaming vessel, of the guide rail as claimed in claim 15, from which rail the cones or cops are suspended with the aid of travelling crabs, has the advantage that it eases the introduction of the cops or cones. By arranging several guide rails, utilization of the steaming vessel can be improved.
The hot-air nozzles according to claim 16 prevent water condensation at the
