ABSTRACT:
FIELD OF THE INVENTION
The present invention pertains to a handling system for filament bobbins or doffs in a spinning mill with a spinning area and a storage area, wherein the handling system connects the spinning area to the storage area and has a transport means for handling and transporting the doffs as well as a separating device for the filament bobbins.
BACKGROUND OF THE INVENTION
Such a handling system has been known from practice. It connects the spinning area with the storage area and has a transport means with a separating device in the spinning area. The transport means comprises a plurality of individual systems, namely, so-called doffers and an overhead monorail conveyor. The doffers have a displaceable and rotatable column, which is rail-borne on the floor and in the head area, with an individual pin for taking up a doff comprising a plurality of filament bobbins. The individual doffer can travel to and fro only in the aisle in front of the spinning frames set up in a row and it can transfer the doff to a carrier of the overhead monorail conveyor in the aisle area. This requires a plurality of doffers. During this transfer, which takes place in the spinning area, the filament bobbins are separated by the doffer and are attached to the carrier on the overhead monorail conveyor. The visual inspection of the individual filament bobbins also takes place in the spinning area. The second transport system then delivers the filament bobbins into the bay area, where they are transferred once again to a high-bay warehouse storage and retrieval system and are stored in a suitable manner. The prior-art technique has the drawback of requiring very much time and complicated apparatus and control engineering. The coordination of the two transport systems and the need that a carrier must be made ready in time for the loaded doffer are also problematic. The automation of the handling system is not always ensured as a result.
SUMMARY AND OBJECTS OF THE INVENTION
The primary object of the present invention is to show a better and more efficient handling system for filament bobbins or doffs.
The present invention accomplishes this object by providing a handling system with a spinning area and a storage area separate from the spinning area. A transport means connects the spinning area to the storage area for handling and transporting the doffs. The transport means includes a multi-column support for a plurality of the doffs. A separating device is arranged separately from the transport means for separating filament bobbins. A transfer station is arranged between the transport means and the separating device. The transfer station has a multi-column support for a plurality of the doffs.
The time-consuming separation of the filament bobbins and the visual inspection are moved away from the transport means and the doffer in the handling system according to the present invention. The transport means is relieved as a result. In addition, the transport means has a multi-column support for handling and transporting a plurality of doffs, which can then be transferred completely at once to a transfer station, which is arranged upstream of the separating device and is likewise provided with a multi-column support. The conveying and performance capacity of the transport means increases as a result. In addition, the travel movements of the transport means are reduced despite the increased doff output.
On the whole, the handling system becomes substantially more efficient, faster, less expensive and more economical. In addition, the transfer operations for the filament bobbins or doffs and optionally also for the empty bobbins become simpler, which requires a less complicated mechanical design. In particular, no overhead transfer is necessary any longer.
The transport means according to the present invention has other advantages as well. It is not necessarily limited to one path of movement any more, but it can move in a substantially larger area and preferably also outside the spinning area. In particular, the individual transport means may also handle a plurality of rows of spinning frames. This also makes it possible to make do with fewer apparatuses in conjunction with the increased take-up and transport capacity. In addition, the transport means may be connected to the areas of the spinning mill, e.g., a crimping device or the like.
The transport means may have any desired design. In the preferred embodiment, it is one or more floor-bound vehicles with inductive guidance and remote control or an overhead conveyor. The handling system according to the present invention makes do with one transport system and no longer needs the bipartition into frame-bound doffer and overhead monorail conveyor. The design effort is substantially reduced as a result. The transport means according to the present invention can perform all conveying operations up to the transfer station, which saves time and money.
The shifting of the time-consuming separation of the filament bobbins of the doff from the spinning area into the storage area is of particular advantage. More time and more place are usually available there. In addition, the visual inspection can be better accommodated here and can even be shifted to an area just in front of the storage of the filament bobbins. As a result, all the effects of errors that may occur up to the storage can be taken into account and corrected if necessary.
The transfer station preferably forms the interface between the spinning area and the storage area. It makes it possible, in particular, to accommodate these two areas separated in space, e.g., on different floors of a mill. The transfer device with a conveying means of its own may optionally also be equipped with one or more storage places for this purpose. It may also act as a buffer between the spinning area and the storage area. For mechanical engineering and capacity reasons, it is useful to integrate the separating device within the transfer station.
The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better understanding of the invention, its operating advantages and specific objects attained by its uses, reference is made to the accompanying drawings and descriptive matter in which preferred embodiments of the invention are illustrated.
