Abstract

A reception device for reeled textile material 4 consists of a hollow circular base plate 1, a core tube 2 connected concentrically thereto, and hollow spears or spindles 3 arranged at a uniform distribution over the surface of the base plate 1. Fixing discs 6 which are adapted to the diameter of the base plate 1 and have central and peripheral apertures are fitted over the core tube 2 and the spears or spindles 3 with reels 4 of material therebetween to prevent buckling of the spears as a result of centrifugal force when the device is rotated about its axis during dewatering following wet treatment. <IMAGE>

Description

SPECIFICATION A device for reception of textile material that is to be treated This invention relates to a device for reception of textile material which is wound onto carriers and which is to be wet-treated and preliminarily dewatered.

Known reception devices for reeled textile material that is, for example, to be dyed are generally used inside sealable dyeing containers and include a circular base plate which is hollow in design.

Arranged on the upper side of the base plate at a uniform distribution are dyeing tubes or so-called spears or spindles which are similarly hollow in design. These are radially perforated and their cavity communicates with the cavity of the base plate.

Treatment liquor is fed in by way of a pipeline connected to the cavity of the base plate and, by way of the perforations of the spears or spindles, acts radially outwardly on packages or reels of textile material which are slipped onto said spears to form package columns. The treatment liquor penetrates the textile packages or reels radially and is either carried away by a pipeline connected to the container or is fed afresh to the cavity of the base plate. The direction of flow of the liquor circulation can also be reversed, so that the packages of textile material are acted upon radially from the outside inwardly, to ensure uniformity of dyeing.

Afterthe wet treatment is finished the textile material together with the reception device is removed from the container. The material is then transferred into a centrifuge for preliminary dewatering and for this the package columns have to be removed from the spears and either be dismantled into individual packages or retained in column form for insertion into a centrifuge drum. The inside of the centrifuge drum is provided with concave recesses adapted to the diameter of the packages, so that during centrifugation the centrifugal force does not deform the packages too much.

Thus, wet treatment and preliminary dewatering of reeled textile material currently requires considerable expenditure on apparatus and on labour two minimise stressing of the textile material during the two types of treatment.

The object of the invention is to provide a reception device for wound or reeled textile material which is so adapted to the different stresses that it is possible to leave the textile material, during the wet treatment and the preliminary dewatering, in unvaried form thereon, so that considerable handling expenditure is abolished.

This object is achieved in accordance with the invention by provision of a reception device consisting of a hollow circular base plate on which radiallyperforated spears or spindles, which are also hollow in design, and which receive respective package columns formed from packages or reels of textile material are uniformly arranged, the cavities ofthe spears or spindles communicating with the cavity of the base plate, to which a pipeline for treatment liquor is connectable, characterised in that arranged concentrically of the base plate is a core tube which extends above the height of the spears or spindles and onto which fixing discs adapted to the diameter of the base plate can be slipped, which discs have, in addition to a concentric opening adapted to the outside diameter of the core tube, apertures adapted to accomodate either the spears or spindles or the package carriers, respectively.

The core tube in accordance with the invention provides the possibility of mounting the reception device rotatably for convenient charging at one side into an initially horizontal supporting mandrel and of slipping packages of textile material and fixing discs onto the spears or spindles that can thereby be brought successively to an expedient working height. The loaded reception device is introduced in a dyeing container, removed therefrom after the dyeing process and in so doing optionally transferred by a swivel motion of the mandrel into a vertical position, in order with the aid of a lifting appliance to be inserted into a centrifuge drum which rotates about a vertical axis.

In this way, manipulation of the individual packages or reels between the wet-treatment process and the preliminary dewatering process is abolished. In addition to this, the centrifuge drum does not need a special internal jacket design since the core tube in conjunction with the fixing discs stabilises the spears or spindles against the centrifugal force and these in turn prevent the columns of packages from excessive deformation.

Preferably the fixing discs are arranged on the core tube at a uniform distribution over the height of the spears or spindles and two neighbouring fixing discs are arranged at a spacing from one another which corresponds to a multiple of the height of one package or reel of textile material. As a result of this, uniform stabilisation of the spears or spindles and of the package columns located thereon, over the height thereof is achieved. In this respect it is convenient, even in the case of comparatively thin fixing discs, if these are arranged at intervals between, for example, three consecutive packages or reels in a package column.

Preferably a fixing disc masks the end faces of the package columns which are averted from the base plate, which disc can be pressed axially against the package columns supported on the base plate by clamping mechanisms at the ends of the spears or spindles. The base plate at one end, a fixing disc at the other end, and the fixing discs distributed therebetween result in a compact unit consisting of reception mechanism and textile material which meets all the requirements with respect to the two treatment processes.

In a preferred embodiment of the invention a cylindrical guide collar is provided in the concentric opening of each fixing disc, which collar has an inside diameter adapted to the outside diameter of the core tube. As a result of this, with good guidance, a tight tolerance between the free aperture diameter of the fixing discs and the outside diameter of the core tube can be chosen, whereby the axial displacement of the fixing discs and their exact radial positioning can be facilitated.

To additionally facilitate the axial displacement and the positioning of the fixing discs, however, cylindrical reception collars having edges tapering to the diameter of the core tube are advantageously arranged on the core tube in the regions where the fixing discs are to be located. With this particular design, the fixing discs can readily be shifted or slid along the core tube with comparatively great play and they are centred only by the tapering edge regions of the reception collars.

An exemplified embodiment of a reception device in accordance with the invention is shown schematically in the drawing, in which: Figure lisa side view of the device partially in section; and Figure 2 is an end view of the device shown in Figure 1.

The illustrated reception device, which is arranged on a transportation truck, consists of a circular base plate 1 which is hollow in design and is connected concentrically to a core tube 2 which protrudes from one side of the plate 1.

Hollow spears or spindles 3 are arranged with uniform distribution over the basal surface area of the base plate 1 parallel to the axis of the core tube 2.

These spears or spindles are arranged in two concentric circles and reels or packages 4 of textile material are slipped onto them to form package columns 5. The reels or packages 4 of textile material are preferably seated on carriers (not shown), which can be slipped into one another or else be shortenable by a specific amount for homogeneous axial compaction ofthe package columns 5.

A number of fixing discs 6 which are of substantially the same diameter as the base plate 1 and which each have a concentric opening 7 adapted to the outside diameter of the core tube 2 are arranged on the core tube 2 and are distributed uniformly over the longitudinal extent thereof. These fixing discs 6 also have apertures 8 for the spears 3 or for the carriers of the packages of textile material.

Conically tapering reception collars 9 are seated on the core tube 2 in the region of the fixing discs 6.

The fixing discs 6 themselves each have, in their respective central openings 7, a cylindrical guide collar 10, which is adapted to the outside diameter of the reception collars 9 and in use fits around a respective collar 9.

If the carrier is used for horizontal HT-dyeing apparatus, the terminal fixing disc 6 and the base plate 1 are fitted with rollers or casters 11.

As indicated in Figure 1, the arrangement of the fixing discs 6 is so selected that in each case a fixing disc 6 follows three reels or packages of textile material slipped successively onto each spear 3. A package column 5 formed from nine reels or packages 4 of textile material is in this way subdivided by three fixing discs 6, in which respect the base plate 1 at one end and one of the fixing discs 6 at the other end masks all the package columns 5.

With known clamping devices 12 arranged on the ends of the spears or spindles 3, the package columns 5 can be axially compacted and, in collaboration with the base plate 1, the core tube 2 and the fixing disc 6, be held together in a compact unit.

The textile material thus received by the device can be wet-treated and preliminarily dewatered without altering its arrangement, i.e. without manipulation of the individual reels or packages of textile material or of the package columns formed therefrom being necessary or special additional precautions having be taken against a change of shape during either of these treatment processes.
