A continuous gasket contacts the radial slide and a fluid collector supplies the compartment with pressurized air to seal the compartment. The fluid collector includes a rotary portion with first fluid routes, and a fixed portion integral with the fixed part of the facing head with second fixed fluid routes together supplying the rotary part with a coolant, supplying the compartment with pressurized air, and transporting the oil for locking the radial slide.
Abstract:
A method to control a mixer includes an input to a control and command unit including a plurality of input data correlated to a formulation of a mix, a detection step to detect the values of an electric quantity characteristic of the electric power line of a drive unit in the mixer, a processing step where data is processed to calculate the overall active power, and to carry out verifications, comparing the data processed with one or more of the respective data introduced among the input data, in order to transmit to a controller that commands the mixer, a consent signal to discharge the mix or an anomaly signal.
Abstract:
A method to control a mixer (10) for concrete, mortar, powders, dry and semi-dry granulates, cement-based mixes or similar or comparable mixes or mixtures, comprises an input step in which it provides to communicate to a control and command unit (15) of the mixer (10) a plurality of input data correlated to the formulation of the mix that has to be treated in the mixing cycle, a detection step in which it provides to detect the values of an electric quantity characteristic of the electric power line of a drive unit (12) comprised in the mixer (10), a processing step in which the control and command unit (15) processes the data detected in the detection step in order to calculate the overall active power that is generated as a function of time, and to carry out one or more verifications, comparing the data processed with one or more of the respective data introduced among the input data, in order to transmit to a programmable logic controller (14) that commands the functioning of the mixer (10) alternately a consent signal to discharge the mix subjected to the mixing cycle, or an anomaly signal selectively correlated to the verification or verifications that have had a negative outcome, so that the operator can respectively command in the first case the discharge of the mix from the mixer (10), and in the second case the consequent corrective actions on the mixing cycle.
Abstract:
A facing head (1) is here described comprising a fixed part (4), couplable with a head of a machine tool (2) via an interface plate (3), a rotary part (5), wherein a compartment (35) is placed internally to which drive means (100) and measurement means (101) are housed for driving and measuring a radial slide (6) which is supported by the rotary part (5) so as to close the compartment (35), and at least one electric collector suitable for transmitting the electrical signals for controlling the drive means (100) and measurement means (101) used for driving and measuring the radial slide (6). The facing head (1) comprises a continuous gasket (40), which is configured in such a way as to completely make contact with the radial slide (6) and is housed inside a respective recess (34) which externally surrounds the compartment (35), and a fluid collector, which is suitable for supplying the compartment (35) with pressurized air, so that the pressure inside the compartment (35) is higher than the atmospheric pressure, so as to seal the compartment (35). The fluid collector comprises a rotary portion (22), which is integral with the rotary part (5) of the facing head (1) and comprises first fluid routes (43) internally thereto, and a fixed portion (23), which is integral with the fixed part (4) of the facing head (1) and comprises, internally thereto, second fixed fluid routes (45) coupled with the first fluid routes (43) to supply the rotary part (5) with a coolant, to supply the compartment (35) with pressurized air, and to transport the oil necessary for automatically locking the radial slide (6).

Abstract:
A cart for transporting objects and various goods, in particular on golf courses, comprising at least one electric traction motor fed by at least one set of accumulators installed on board the cart, a series of ultrasonic sensors apt to detect the signals coming from an external source of signals, and a microcomputer control unit which interfaces with said sensors and with an electronic speed regulator of said at least one electric motor, is automatically guided to maintain a pre-determined position set in respect of the position of said extemal source of reference signals. Special algorithms are implemented in the microcomputer control unit of the cart in order to exactly determine the mutual position cart / source and to avoid interferences with similar carts operating in the same area.
