- 18. The machine as de fined in claim 1; and further comprising:
- means for taking in textile tubes including clean textile tubes and the textile tubes with yarn residue;
- means for circulating all of the textile tubes so that the clean tubes are separated from the tubes with yarn residue; and
- means for arranging the clean tubes for uniform stacking.
- 19. The machine as defined in claim 17, wherein said taking-in means includes an unpiling device, said unpiling device including a first pair of detachable rollers and a second pair of detachable rollers, said rollers of each of said pairs being biased toward each other and extending in a longitudinal direction, said second pair of rollers being arranged forward of said first pair of rollers transverse to said longitudinal direction, said second pair of rollers rotating at a faster rate than said first pair of rollers so that a stack of tubes separates from each other as the stack of tubes passes through said first pair rollers and then said second pair rollers, said taking-in means further including endless belt means for transporting the tubes from said unpiling device to classifying means.
- 20. The machine as defined in claim 18, further compromising classifying means including a guide, a plurality of adhesive members, and conveyor means for conveying the textile tubes on said plurality of adhesive members, said plurality of adhesive members being pivotally articulated to said conveyor means, said guide being formed so that when said plurality of adhesive members travel on said guide, the clean tubes being conveyed fall off by gravity and yet the tubes with yarn residue that are being conveyed are retained by said plurality of adhesive members.

BACKGROUND OF THE INVENTION
This application is a continuation-in-part of U.S. patent application Ser. No. 756,964, filed July 18, 1985 now U.S. Pat. No. 4,783,887 granted Nov. 15, 1988.
The present invention relates to a machine designed for classifying, cleansing and arranging textile tubes.
Various machines of this type for the classification and arrangement of textile tubes are known for example from Italian patents, Nos. 748,403, 988,521, and 922,333. In these machines, inclined elemental planes are used to obtain the classification necessary. However, this leads to intermingling of clean tubes and tubes holding residues of yarn.
Spanish patent No. 504,516 by the same inventor illustrates a typical unpiling device. When tubes are fed horizontally into an intake section, the tubes themselves may be stacked on top of each other and require separation from each other. An unpiling device is able to unstack the tubes by separating them as the tubes pass between two pairs of rollers.
FIGS. 29, 30 and 31, 32 demonstrate separation or unstacking of the tubes from each other where the narrower end of the tubes is fed first (FIGS. 29, 30) or the wider end of the tubes is fed first (FIGS. 31, 32) into the unpiling device.
The tubes T are fed first between first rollers 290, 270 and urged forward between second rollers 300, 280. Second rollers 300, 280 rotate faster than first rollers 290, 270 so that the first fed tube is urged forward by the rollers 300, 280 at a faster rate than is the tube underneath, which is still being urged forward by rollers 290, 270. Top rollers 290, 300 are free to rotate but are elastically compressed toward bottom rollers 270, 280 respectively to thereby ensure that the tubes urge forward between each pair of rollers.
It is an object of the present invention to overcome the deficiencies of the prior art and to eliminate labor to the greatest extent possible by having all operations performed automatically.
Pursuant to this object, and with others which will become apparent hereinafter, one aspect of the present invention resides in a machine which is electromechanical, pneumatic and hydraulic, and is fed by tubs or containers which are emptied into a storage bin by means of a dumping device. Tubes are then classified by means of conveyor belts, tubes with yarn residues being separated from clean tubes. The clean tubes are transported directly to the head of the arranging section of the machine and are counted and packed in removal tubs in the same direction or alternating, as necessary. The tubes with yarn residues are lifted and deposited in vibratory bins which feed a cleaning head. The vibratory bins automatically perform the operations of alignment, orientation of the tube and verification that the tube has entered the head correctly.
Because of its versatility, the machine is capable of cleaning tubes of various sizes without having to be adjusted. Alternatively, their cleaning action may be supplied independently of the arranging section.
The conveyor belts of the present invention have articulated elements which allow only the clean tubes, but not those holding residues of yarn, to fall, by gravity. This represents a great advantage over the embodiments of the Italian patents mentioned, in which recourse is necessitated to a system of inclined elemental planes to obtain in a very imperfect way the classification.
The machine of the present invention is advantageous to the prior art, since now perfect selection of the tubes is obtained, so that if upon intake into the machine a tube is lacking yarn residues, it passes immediately to conditioning for subsequent use and, if the tube appears with yarn residues, such residues are eliminated in a simple and effective way.
It is a further object to provide a device for capturing, turning and aligning the textiles tubes for subsequent removal of yarn residue. Such a device feeds the tubes through a constricted mouth at the end of a slope to a clamp, which aligns the textile tubes as required to arrange a wider end of the textile tubes forward.
It is another object to provide a removing device which receives the wider end of the textile tubes first and removes the yarn residue by guiding jaws into the yarn residue and yet minimizes the pressure being applied on the textile tube itself.
The novel features which are considered as characteristic for the invention are set forth in particular in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
