An automation unit for handling component carriers has an enclosure for arranging components carriers within a first, a second and a third stacking space. The enclosure has a loading opening for the first stacking space, a transfer device for transferring component carriers between the stacking spaces, and a separating device to selectively separate or release the first stacking space inwardly. A safety system for an intervention area is at the loading opening to interrupt the operation of the automation unit if it detects an intervention. The safety system may switch to partial monitoring mode, to full monitoring mode after completion of an automated loading process or deactivate in a manual loading mode when the separating device separates the first stacking space. The safety system may switch to full monitoring mode before the separating device releases the first stacking space. The automation unit can be loaded both automatically and manually safely.

A machine tool capable of reducing entry of a workpiece chip into a product discharge chute. A controller controls a receipt of a product made of a workpiece held by a first spindle by a product receiver in a product receiving position, movement of the product receiver to a product dropping position and rotation of the product receiver to drop the product to the product discharge chute through an opening of the product discharge chute, and movement of the product receiver to the product receiving position to receive the product again. A second spindle is kept on standby in the product dropping position during which the opening of the product discharge chute is closed by the product receiver.

The present disclosure relates to an automatic tool changer for a machine tool which can change a tool mounted on a tool post by moving both of a magazine and a tool post to be concentric in order to change a tool in a horizontal type machine tool such as a lathe or a horizontal type turning center; a method of controlling the automatic tool changer and a machine tool including the automatic tool changer.

The present invention includes a plurality of protective bodies (13, 14, 15) sequentially connected in a moving direction of a moving body and separating a movement path of the moving body from the outside. The protective body (15) at a first end is connected to a predetermined end (12a) of an area to be protected, and the protective body (13) at a second end is connected to the moving body. The plurality of protective bodies (13, 14, 15) are configured to be expanded and contracted as a whole by movement of the moving body. A structural body (35) having a groove (35a) having a top opening and forming a flow path is provided. The structural body (35) is arranged along the protective bodies (13, 14, 15) below the protective bodies (13, 14, 15) or arranged along the protective bodies (13, 14, 15) such that the lower ends of the protective bodies (13, 14, 15) are inserted in the groove (35a) through the top opening of the groove (35a). The groove body (35) is provided with a nozzle (38) ejecting a liquid into the groove (35a), and a pressurized liquid is supplied to the nozzle (38) from a liquid supply source (40).

A magazine comprises: a conveyer unit that has a plurality of tool pots that each hold a tool detachably and conveys the plurality of tool pots; and a magazine cover that accommodates the conveyer unit. The conveyer unit allows a tool to be manually attached to and detached from a tool pot conveyed to a predetermined position. The magazine further comprises a display unit that is provided inside the magazine cover and displays a first design.

The first design represents an arc or circumference for a diameter corresponding to a maximum diameter of a tool which can be held by the tool pot.

A chip scattering prevention cover (1) is attached to a head portion (6b) of a rotary cutter (6). The cover (1) includes an annular portion (1a) configured to be detachably fitted over an outer peripheral edge of the head portion (6b), and a plate portion (1b) extending inwardly of the annular portion (1a) from an inner circumference portion of the annular portion (1a). The plate portion (1b) is configured to cover a region of a cutout gap (6e) of the rotary cutter (6) corresponding to the head portion (6b) with the annular portion (1a) being fitted over the head portion (6b). The annular portion (1a) and the plate portion (1b) are flush with a surface of the head portion (6b) when the annular portion (1a) is fitted over the head portion (6b).

A work holding clamp system for securing a workpiece to a work surface having a work surface T-slot arranged along an ‘X’ axis, comprised of a base plate secured to the work surface and having a plurality of T-slots, each of the plurality of T-slots are aligned with one of a plurality of axis including at least the ‘X’ axis and a ‘Y’ axis that is transverse to the ‘X’ axis. The work holding clamp system includes a workholding element selected from the group consisting of wedge clamps, pivot clamps and workstops, that may be secured within a T-slot of the plurality of T-slots provided in the base plate.

A confinement cabin has a load-bearing structure, confinement walls connected to the load-bearing structure to delimit an inner space of the cabin, an access opening to the inner space, and a door connected to the load-bearing structure to close the access opening. The door is movable in opening and closing with a pivoting-tilting movement and has a movable arm which at a first end is rotationally connected to the load-bearing structure to rotate around a hinging axis, and a closing panel rotationally connected to a second end of the movable arm to rotate around a tilting axis. Rotation of the panel around the tilting axis is synchronized with rotation of the movable arm around the hinging axis by an elastic transmission system between a first pulley coaxial to the hinging axis and a second pulley coaxial to the tilting axis. Rotation of the panel around the tilting axis is in the opposite direction to rotation of the movable arm around the hinging axis.

The present invention relates to a machine door (2), comprising a door frame (10) having an opening (20), at least three door segments (30), and an actuating means (40), wherein the actuating means (40) can adjust the at least three door segments (30) from a position in the door frame (10) that clears the opening (20) to a position out of the door frame (10) that closes the opening (20). In addition, the present invention relates to a machine (1) having such a machine door (2).
