A filter unit is connected between a tray and a discharging duct of a spiral conveyor. The filter unit includes a first filter (perforated metal) that is fixed at a position close to the outer periphery of a conveying spiral, and a second filter (mesh filter) that rotates on the outside of the conveying spiral and the first filter. A washing nozzle sprays a washing liquid on the second filter. The chips captured by the first filter are scraped by the rotating conveying spiral and delivered back to the conveying path and the chips passing through the first filter but captured by the second filter are removed by the washing nozzle and delivered back to the conveying path. The washing liquid is sprayed at a predetermined angle from the washing nozzle and collides with vanes arranged on the outer periphery of the second filter and provides rotational force on the second filter.

The present invention relates to a transport device (100) for transporting one or more handling devices, each for handling a pallet (300) and/or a workpiece (1) on a machine tool (1000) which is set up on a base surface for machining the workpiece (1), wherein the transport device (100) is freely movable on the base surface for positioning the one or more handling devices relative to the machine tool (1000), in particular within a region in front and/or next to the machine tool (1000) and/or in front and/or next to a working space of the machine tool (1000).

In the internal milling machine according to the invention for milling a work piece that rotates during machining with an annular internal milling cutter (5) on the one hand side the Z slide (4a, b) of each tool support (3a, b) includes a pass through opening and on the other hand side the transversal slide (7) supporting the internal milling cutter (5) is move able in the X-direction, the running direction of the mounting surface (1a) of the bed (1) wherein the mounting surface slopes downward in a forward direction. Based on this general configuration and in particular the arrangement of the Z-slides (6a, b) for the at least one tool support (3a, b) outside of the Z-supports (16a, b) for the opposite spindle stock (2′) yields advantageous centers of gravity in particular of the move able components and a high level of stability of the machine and therefore high level of machining precision of the machine.

A disassembly mechanism configured to be disposed on a dust collector is provided, including: a fixation assembly, including a first fixation portion and a second fixation portion, the first and second fixation portions being configured to be disposed on a base and a barrel of the dust collector respectively, the second fixation portion including a slot; an actuating mechanism, including an engaging portion being disengageably engaged laterally with the slot and a connecting portion being movably disposed on the first fixation portion, and the engaging portion being movable with the second fixation portion. A dust collector including at least one aforementioned disassembly mechanism is also provided.

The invention relates to a method for the chip-removing production or machining of a workpiece by means of a tool, in which method a liquid, which mixes and accumulates with the chips produced during the machining process, is used for lubricating and/or cooling the machining process, and the chips are discharged from the accumulation counter to the downhill force along a discharge path by means of a magnetic force, wherein a return flow of the liquid carried by the discharged chips occurs due to the downhill force, and the return flow is deflected out of the discharge path and/or the discharge path has at least one point at which the supporting surface is temporarily withdrawn from the discharged chips.

A conveyor comprises an endless belt and a belt return device. The endless belt comprises an upper run and a lower run and is configured to convey conveying material in a conveying direction. An intermediate space is defined between the upper run and the lower run. The belt return device facilitates transitioning of the endless belt between the lower run and the upper run. The endless belt defines at least one passage opening which allows the exit of at least a portion of an intermediate space material which is formed by a portion of the conveying material which has reached the intermediate space. At least a portion of the endless belt comprises a conveyor track and a passage track. The passage track defines the at least one passage opening. The conveyor track and the passage track are arranged side by side in the conveying direction.

A screw conveyor including a container-type main body provided with a storage tank; a horizontally oriented delivery pipe a front end of which is connected to the storage tank; a discharge pipe connected to a rear end of the delivery pipe and arranged inclined upwards from a connecting end to another end; a screw arranged across an inside of the storage tank and the delivery pipe; a drive mechanism configured to apply rotation to the screw via a rotation transmission section on a front section of the storage tank on an opposite side to the delivery pipe; and a screw support structure in which multiple support blocks configured to slidably contact the screw are fixed to an inside surface of the delivery pipe at different positions, and in which one or two or more of the support blocks are fixed to a front side of the delivery pipe.

Based on this general configuration and in particular the arrangement of the Z-slides (6a, b) for the at least one tool support (3a, b) outside of the Z-supports (16a, b) for the opposite spindle stock (2) yields advantageous centers of gravity in particular of the move able components and a high level of stability of the machine and therefore high level of machining precision of the machine.

A free-floating, sweeper head for use in a pneumatic chip collector system. The sweeper head includes a sweeper mechanism and a connector configured to be coupled to the pneumatic system. The sweeper head includes a horizontal plate, a skirt that extends transversely from the plate along a portion of a perimeter of the plate, and an aperture that extends through the plate and is in communication with the connector. The sweeper mechanism has a drive disposed on the plate, a set of blades disposed below the plate, and a shaft that operatively couples the drive and the set of blades. The skirt creates an opening below the plate that is adapted to receive at least one chip when the set of blades rotates.
