DESCRIPTION:
BRIEF SUMMARY
The invention relates to a method for shortening of the conveying paths during the heat treatment and/or humidification, in a steaming vessel, of cops spun onto bobbins at several spinning stations of a spinning machine. The invention further relates to a device for spinning, for heat treatment and/or humidification of yarns, comprising:
a spinning machine with several spinning stations arranged in a row, on which cops are produced, each of which contains a bobbin;
a conveyor for the removal of the fully-spun cops;
a handling device for delivering empty bobbins to the spinning machine and the removal of cops from the spinning machine, and the setting down of the cops onto the conveyor;
a steaming vessel for heat treatment and/or humidification of the fully-spun cops.
As used herein, the term "cop" generally refers to the spool onto which the fibers are placed after the spinning stage, as well as the mass of fibers themselves, while the term "bobbin" generally refers to the spool onto which the fibers are placed after the treatment process, as well as to the mass of fibers thereon. Those skilled in the art appreciate that the terms are generally interchangeable, often differing only in reference to size of the spool. Both typically have a core or "pirn" about which the fibers are wound. The use of a specific term herein is not intended to foreclose the use of the other in the invention.
With a known method and a known device of this type (FR-A-2620743 and RF-A-2614633), the steaming vessel is located between the spinning machine and the winding machine. By means of a conveyor belt, the fully-spun cops are moved from the spinning machine into the steaming vessel. Subsequently, the fully-steamed cops are moved from the steaming vessel to the winding machine by means of a second conveyor belt. A handling device is thus required to move the fully spun cops from the spinning machine onto the first conveyor belt. In addition, a second conveyor belt is required between the steaming vessel and the winding machine. With the known devices, there is thus need for two conveyor belts, which take up much space. With the known methods, there exists also the danger of material mix-up (of the cops).
Two of the objects of the invention are:
a) to provide a method for the heat treatment and the humification of cops, which can be carried out at an expenditure as low as possible and with changes in the equipment that require as little additional space as possible.
b) to provide a device which, in a manner as space-saving and simple as possible, facilitates heat treatment and/or humidification of cops.
According to the invention, the first of the above-mentioned objects is achieved in that each cop is subjected to heat treatment and/or humidification directly at the spinning station of the spinning machine, in order to avoid long transport paths between spinning machine and steaming vessel. (The term "spinning station", used in the claim, should be understood as referring to the space required--for yarn ballooning--around the cop to be produced.)
Thanks to this method, heat treatment and/or humidification of the cops is effected in direct proximity to the spinning stations of the spinning machines, obviating the need for a conveyor belt between spinning machine and steaming vessel. A particular advantage resides in the fact that dwelling time during and after steaming is largely freely selectable. Therefore, the cops need no longer be removed from the materialflow procedure. The method according to the invention can be carried out faster than the conventional method and precludes material mix-up. Furthermore, as compared to the known spinning plants with remotely placed steaming vessel, very much space is saved. The steaming vessel is designed as closable, open conduit in the form of an elongated trough.
The second of the above-mentioned objects, that is, the provision of a device for carrying out the method, is achieved in that, according to the invention, the steaming vessel comprises a number of steaming stations and is mount
