screw rotates in the pipe, but largely in one can also be held in the upstream direction of rotation, while the conveyor screw provided conveyor pipe several branch screw rotates relative to the mass and the pipe. Conveying pipes at an acute angle to the conveying direction - With a screw conveyor, the conveying must open, which in turn means that a screw can extend practically over the entire length of the large number of machine tools on a conveyor-conveyor pipe, ie the screw conveyor pipe can be connected In this case, it is not suitable to force a mass through a pipe, but the conveying energy from the beginning of the conveying, which is several times longer than the conveying pipe, is introduced and the chips from the screw. The conventional screw conveyor branch conveyor pipes in the manner of a jet pump causes only a slight compression of the chips that are carried along in the conveyor pipe,
derten mass. The cross section of the expediently increases

The invention is based on the object of creating a conveyor pipe at the confluence points of the branch device, which is able to accommodate metal conveyor pipes to accommodate the increasing chips or similar materials over long distances, including the total mass of the metal chips can,
with a change of direction, with simultaneous compression. 15 If the conveying pipe is so long that it can be conveyed on the device, the materials to be conveyed route requiring a renewed supply of conveying energy can come from several sources. is borrowed, you can according to a variant of the invention

This object is provided in a device of the invention that a screw containing a Initially described type according to the invention that pipe section is switched into the conveyor pipe, so solved by the fact that the channel is smooth on the inside, possibly so that the metal chips inherit from this screw Elbow-having delivery pipe is again supplied with energy. The supply of the metal and that the drive, as known per se, can be made from a chip axially or laterally via an opening rotating in a tubular housing and placed in a hopper.

Axial direction reciprocating driven The term "delivery pipe" is in the context of this

Snail exists. 25 Description is to be understood in a very general way insofar as

The invention is based on the knowledge that as the delivery pipe, for example, also on the top side in the Metal shavings have the property that they have an angle of about 90 ° or less a certain compression a furnace introduced into it and with funnel-shaped, obliquely upward energy in the manner of a solid body can be provided with almost running side cheeks, that is Pass on without reluctance in the direction of the power line. 30 forms a kind of channel.

The device according to the invention is suitable for the comminution of the conveyed metal chips for conveying masses which have these properties or the like can in an expedient embodiment of the heirs. With a device according to the invention at the foremost and / or the foremost one can metal chips or the like masses with the screw threads, a knife and on the edge of the feed hopper adjoining the described properties over very long feed hopper Inside smooth conveyor pipe, which can also be fitted with a counter knife.
Elbow can contain, transport, where the one embodiment of the invention provides, from a rotating and in the axial direction back and that the axial drive of the worm from an existing in the driven worm to the worm axis and with the worm drive only a fraction of the Length of the conveying path 40 kenrohr connected, occupies both sides with pressure medium and at the beginning of the conveying tube is arranged to be acted upon by piston, the cylinder of which is net. With the device according to the invention it consists of an axially fixed tube, which is provided with a rotation and is provided with a drive, which is provided between that of the metal chips. The metal shavings from the conveying device consisting of the screw tube and the piston therefore only take up a relatively small volume, and the compression of one side of the piston in the middle of the device is so uniform that the device can be operated ge piston runs.

measured the invention practically even for metering. The axial drive of the screw can also be from can use. Compared to the known one arranged in the screw axis and with Conveying devices for metal chips is connected to the screw tube in the front 50, in the sense of Direction according to the invention which beZeiteinheit per meter and per screw feed on one side with pressure medium the amount of chips conveyed is much larger, there are impactable pistons on which to return and also the investment weight is considerable because the worm is attached to a spring that is cheaper with it. In the device according to the invention rem other end attached to the machine frame there is an automatic comminution of the metal 55 is.

This delivery pipe 10, which is extraordinarily long 25 The other side 23 of the annular piston 21 is over and not only a straight, but also a connecting nipple 46 on the core piece 29 can have a beaufgeniform course, is a short beat, the pressure medium over a Bore 47 upstream of a pipe section which forms the housing 12 of the screw 14 in the core piece 29 in a screw 14 which transports the metal chips axially within the screw. The 14 arranged pipe 48 arrives from which the housing 12 has at the top in the area of the front 3 ° pressure medium in the interior 49 of the tubular end of the retracted screw 14 an up-screw axis 19 arrives to over a or mehgabeinfach 15 through which the metal chips of the rere radial bores 50 in the screw axis 19 screw 14 are fed. This feed trench in the cylinder space 51 between the pipe 24 and the 15 is to arrive asymmetrically to the vertical center plane of the screw axis 19,
formed by the housing 12 in such a way that it feeds the screw 14 with a sealing plate 53 located in metal chips not only at the top but also on the radial plane, where the screw flights closed when the screw was advanced 14 prevents turning from top to bottom, while that means that the metal chips get into the space behind the housing 12, the worm flights 16 on the other circuit plate 53.
Side where the worm threads move upwards. The described device works as follows, largely encloses. This results in the following: The metal chips to be conveyed are fed into the feed hopper 15 via the metal chips when they pass into the screw flights. The screw 14 steadies and at the same time prevents that when the screw is withdrawn, the screw between the screw flights 16 is initially only set in rotation and conveys the metal chips into the metal chips that can be conveyed back into the feed hopper tube 10 from which it is assumed let it be that it will first appear at 15. The screw flights 16 are empty and slowly fill with metal chips. Arranged on the screw tube marked 17, which is firmly connected to an end plate 18 for the foremost or the foremost screw threads, knives 36 can be attached to the 16, which in turn is a tubular screw axis 19 fixed counter knife 37 to which the conveyor tube 10 is connected.

At the rear end of the tubular The metal chips gradually fill the front screw axis 19, an annular piston 21 is a permanently installed area of the conveying pipe 10, and due to their wall friction, the two opposite piston sides of which they supply the following metal 22, 23 can be acted upon with pressure medium in order to retract the chips a certain resistance, which advances to a screw 14 in the axial direction or seals the metal chips in the conveying pipe 10.

When the screw 14 uses its energy, which serves the conveying pipe 60, from the sides in FIG. 1 left end position, ie the screw 62 arranged in front of it is delivered, is reached at the thrust end position, the printing with embodiment according to FIG. 4 provided that the telkanal 45 relieves pressure and at the same time pressure medium via conveyor pipe 60 ' at its beginning a screw 62' has the bore 47 in the interior 49 and the cylinder 5, the derraum 51 being fed in the conveyor pipe 60 ', so that the Piston side 23 metal chips from the subsequently connecting ring piston 21 is acted upon.
