The invention relates to a device for feeding tubes for yarns to distribution stations via delivery openings with a pulley guided endless pocket conveyor belt, the overhead feed line of which is supplied with the sleeves will.

Devices for automating the removal and placement of the yarn bobbins or bobbin tubes in spinning and twisting machines are widely known. In the course of further development of such a * ⁰ device in which the full bobbins from the spindles of a machine taken together and the empty sleeves are plugged together, it is desirable to have a mechanical conveyor provided by means of which the empty tubes central a Feed point can be brought from to several use stations, for example to distribution stations, by means of which these sleeves are transferred to devices for plugging onto the spindles.

It is the object of the invention to provide such a device to accomplish.

There are already a wide variety of devices for sorting and distributing sleeves known for yarns and the like. For example, a tube sorting machine is known that has an oblique has arranged endless pocket conveyor belt fitted with strips and guided around deflection rollers, the overhead feed line of which the sleeves are fed by a horizontal conveyor belt. On this pocket conveyor belt, the sleeves are rectified by stops and finally at the top two sorting conveyor belts are fed. The through these further sorting conveyor belts Sleeves sorted according to sleeve diameters of the same size on one side are then placed in a collecting container forwarded.

Furthermore, a machine for packing yarn bobbins is already known, which also has a strip occupied and guided around pulleys endless pocket conveyor belt, the overhead Feed line the sleeves are fed.

Proceeding from these known devices provided for other purposes, the invention proposes to solve the problem mentioned at the beginning, namely a device for feeding sleeves Od for yarns. Like. To create individual distribution stations via delivery openings, before that one or several discharge openings under the return line are provided, which is otherwise covered by guide devices downwards.-Preferably is the return line in the area of the feed device for yarn tubes

The conveyor belt 21 then receives the individual sleeves B one after the other in its pockets 21g , and the compressed air nozzle 20 causes sleeves of normal dimensions, the foot end of which is opposite the nozzle, to be brought into the correct position on the conveyor belt 17. Then the sleeves are α by the conveyor belt 21 along the sections 21 and 21 carried and to be then along the curved end of the conveyor belt moves, and the lower portion 21c between the guide plates 55 b and 55 c to pass.

In front of the station 61 for removing unusable tubes, the tubes are guided through the bar 69 in such a way that they assume the desired lateral position, and the tubes that are too short fall at the station 61 through the opening 61a according to FIG. 6 into a suitable container 62 normal size are supported at both ends by the guide plate 55c in the area of the opening 61a and conveyed to the removal station 59.

At the removal stations 59, the sleeves can be discharged under the action of gravity through openings 59 a when one or more of the doors 63 have been pivoted downward and opened, as indicated in FIG. 4 with dot-dash lines. As soon as the desired number of sleeves have been supplied to a specific removal station 59, the relevant door 63 is closed again, ie it is in its position in FIG. 4 pivoted upper position reproduced with volume, so that the subsequent sleeves pass the relevant station and reach the next removal station 59, where they are dispensed when the doors are open; otherwise remaining in the pockets of the conveyor belt 21 sleeves of the feed zone along the bottom portion 21 d fed back, then again taken to by the high-speed portion 21 and then to be discharged at one of the removal stations 59th The sleeves fed to the loading zone at the transition point between the conveyor belts 19 and 21 fall into the as yet unfilled pockets 21g, the width and depth of which only slightly exceed the diameter of the sleeves, so that each pocket can only hold one reel at a time. In order to prevent the supply of too large a number of tubes to the loading zone at the transition point between the conveyor belts 19 and 21, a suitable feedback and control device can be provided by means of which the vibrating slide is controlled according to the tube supply in the area between the conveyor belts 19 and 21 otherwise the vibrating chute can be controlled by hand in a known manner.
