Abstract: A laser cutting head powered by a laser emission apparatus includes a collimation device to collimate a laser beam coming from the laser emission apparatus and a focusing lens which focuses a collimated laser beam from the collimation device. The lens is supported in a casing and is movable along an adjustment direction to change a focal point of the laser beam. A cooling unit is connected with the casing and includes at least one Peltier cell and a heat dissipation element. A thermal conductive element connects a support for the lens with the cooling unit to extract heat generated by the laser beam passing through the lens by thermal conduction from the support and from the lens.

Abstract: An apparatus for measuring a bending angle between two portions of a workpiece in a bending machine includes at least a motion sensor unit provided with a gyroscope sensor, a processing unit connected with the gyroscope sensor and a coupling device for connecting the motion sensor unit with a portion of the workpiece to be bent. During a bending operation of the workpiece the gyroscope sensor measures at least one angular velocity and a related rotation angle of the portion according to an axis and the processing unit receives data from the gyroscope sensor regarding the rotation angle in order to calculate the bending angle as a function of the rotation angle.

Abstract: A laser cutting head powered by a laser emission apparatus including optical transmission devices and associated with a cutting machine tool, includes a collimation device to collimate a laser beam coming from the laser emission apparatus, a focusing device to focus a collimated laser beam leaving the collimation devices, and a casing to house the focusing unit. The focusing unit includes one focusing lens and support devices to house and hold the focusing lens and move it along an adjustment direction within the casing in order to vary a focal point of the laser beam leaving the focusing lens. The laser cutting head includes a cooling unit secured to the casing and heat conducting devices used to connect the support devices with the cooling unit in order to extract the heat generated by the laser beam crossing the focusing lens by thermal conduction from the support devices and the focusing lens.

Abstract: A punching apparatus includes punching tools and actuators positioned above and aligned with the respective punching tools to actuate the punching tools along an operating direction so as to interact with a piece to be worked. The punching tools and the actuators are arranged side by side along at least one row. The punching apparatus includes at least one barrier optical sensor, suitable to generate a light beam that is put side by side to the row of punching tools and actuators, and reference elements, each of which is associated to a respective punching tool and/or actuator to intercept the light beam. The barrier optical sensor is arranged to detect changes in the light beam produced by one of the reference elements moving along the operating direction so as to measure a position and/or a stroke and/or a speed of a punching tool associated to the reference element.

Abstract: A control system for a pneumatic transport system of granular material, which includes a plurality of containers, is configured to manage the filling cycle of each container automatically by monitoring the weight of the transported material continuously, and by optionally monitoring the state of the granular material, for example temperature and humidity of the granular material. The information generated by the control system is provided to a centralized management system, which may be operated entirely or partially through radio signals transmitted by wireless technology.

Abstract: A control system for a multihead weigher for a combinatorial weighing system comprises a plurality of weighing modules each having a weighing bucket for receiving and weighing articles to be weighed, and a weighing module controller (e.g., a state machine) for controlling article weighing, discharge and refill operations of its associated weighing bucket. A central control unit (e.g., a PC) connected to the weighing module controllers over a low speed serial network issues at least one macro-command, such as “discharge and refill” to the weighing module controllers reducing the number of commands issued from central control unit to the weighing module controller which would otherwise occur without the macro-command. The weighing module controllers, in response to the at least one macro-command, perform the steps needed to effect the article weighing, discharge and refill operations. The control system has Internet connection capabilities.
