Provided is a three-dimensional measurement device applicable to a machining machine. A sensor head contains a body and a collet chuck. A light emitting window and a light receiving window are provided on the front end of the body. A non-contact sensor is incorporated in the body. Laser light emitted by the non-contact sensor is radiated onto a workpiece through the light emitting window. Laser light reflected from the surface of the workpiece is received by the light receiving window. A collet chuck is attached to the rear end of the body. The collet chuck has the same shape as a collet chuck provided by each tool housed in a tool magazine of a machining center.

A system, method, and apparatus for changing a set of old tools for a set of new tools may be presented. The system may comprise a crawler robot, a robotic arm, a tool changer, a vision system, and at least one of a tool rack or a storage area. The tool changer may be an end effector of the robotic arm. The tool changer may comprise a number of grippers and a number of movement assemblies. The number of grippers may perform at least one of moving a set of new tools to the crawler robot or removing the set of old tools from the crawler robot. The number of movement assemblies may be associated with the number of grippers. The vision system may be associated with at least one of the robotic arm and the tool changer.

A tool changing device for a machine tool comprises a tool magazine, a transfer device and a linear drive for the tool magazine. The tool magazine comprises a magazine axis, wherein the tool magazine is rotatable about the magazine axis by a rotary drive, and a plurality of holding locations for tools that have a support shaft and a receiving groove. At least some of the holding locations are arranged offset relative to one another along the magazine axis, and at least some of the holding locations are arranged offset relative to one another about the magazine axis. The holding locations are configured to hold the tools at the receiving groove. The transfer device comprises a transfer carriage, wherein the transfer device is movable between a first transfer position in relation to the tool magazine and a second transfer position to transfer tools between the tool magazine and a tool holder of the machine tool. The linear drive is configured to move the tool magazine along the magazine axis relative to the transfer device to provide, together with the rotary drive, a selected holding location in the first transfer position.

Disclosed is a gripping system for receiving a processing tool, and to a storage system. These processing tools are used in processing machines or centres in the woodworking industry. Also disclosed is a processing machine with the above-mentioned storage system. This processing machine is used for processing elongate pieces of wood.

The present invention is a novel lanyard system for a piece releaseably connected to a tool by a piece receiver that includes a lanyard assembly with a two ended strap and a retraction system fixed to the tool in a storage region of the tool. In particular, one end of the strap is connected to the piece and the other strap end is connected to one end of the retraction system. The other end of the retraction system is connected to the tool. The strap is of sufficient length for the retraction system to retract a piece to the storage region after disconnection from the piece receiver. It is contemplated that the retraction system includes at least one spring (coil or helical) to cause the lanyard system to remain under tension while the piece is mounted in a piece receiver, thereby preventing or at least reducing the strap from interfering with the task at hand, the piece, the piece receiver or tool itself. The retraction system has sufficient tensional force to cause the retraction of a piece to the storage region once released from the work region of the tool.

A method and a machine for automatically changing a disc tool to a tool holder of an automated machine working with the disc tools is disclosed. The method includes in the disc tool replacement machine: determining that the tool holder is in a replacement area in the disc tool replacement machine; unfastening a fixing member of the tool holder by applying an unfastening force to the fixing member, wherein the fixing member fixes a disc tool to a backing plate of the tool holder through a through hole at a centre of the disc tool; removing the disc tool from the tool holder after said unfastening; inserting a new disc tool to the tool holder; and fastening the fixing member of the tool holder by applying a fastening force to the fixing member, thus fixing the disc tool to the backing plate of the tool holder through the through hole.

The cutting machine for cutting logs of web material, includes a cutting head arranged along the feeding path of the logs. The cutting head includes a coupling for a disc-shaped cutting blade and is designed to impart the disc-shaped cutting blade a rotary motion around the axis thereof and a cyclic movement to cut the logs into single rolls, and to allow the logs to move forward along the feeding path. The machine also includes a store unit for disc-shaped cutting blades associated with the cutting head. A handling member is provided to remove a worn disc-shaped cutting blade from the cutting head and replace the worn disc-shaped cutting blade with a new disc-shaped cutting blade taken from the store unit.

Tool magazine for the provision of tools for a machine tool, wherein the tool magazine has a multiplicity of receiving positions for tools. A first tool can be removed from or inserted into a first receiving position along a removal direction, and at least one further receiving position for receiving a further tool is provided.

The invention relates to a machine tool cocoon (10) for receiving a workpiece, having a base element (18) on which the workpiece can be disposed, wherein the base element (18) comprises at least one receptacle (47) for receiving and fixing a workpiece (40), and a support device (11) separably connected to the base element (18). The machine tool cocoon (10) can be positioned on a tool position of a tool changing system by means of the support device (11). The invention further relates to a method and a computer program.

A cutting apparatus includes a cutting unit including a spindle as a rotational shaft and a mount flange for mounting a cutting blade thereon, the mount flange being fixed to a distal end of the spindle, a support unit for supporting a cutting blade housed in a blade case, the support unit including a blade case support for supporting the blade case for housing the cutting blade therein, a changing mechanism for dismounting a cutting blade that has been mounted on the mount flange from the mount flange and mounting the cutting blade that has been supported on the support unit on the mount flange, and a moving mechanism for moving the changing mechanism between a changing position, a blade transfer position, and a retracted position.
