Abstract: Device (10) for measuring the level (L) of fluid (F) inside a tank (11) for containing said fluid (F), comprising at least one mobile level blade (12) positioned, during use, inside the tank (11) and at least one sensor (14) configured to detect at least one position of said level blade (12) and positioned, during use, outside the tank (11), wherein said level blade (12) is configured to interact with said sensor (14) in order to determine the level (L) of fluid (F) in the tank (11) in relation to a threshold level (LI), in correspondence with which said sensor (14) is preferably positioned.

Abstract: A machine (10) to automatically prepare a fluid coloring product inside a container (15), which can already contain a base product, comprises a loading station (26), a perforating device to make an aperture in the upper part of the container (15), a delivery device (21) configured to deliver coloring substances inside the container through such aperture, and a closing device configured to automatically closed such aperture with a closing element, after the delivery of the coloring substances.

Abstract: A perforation device to perforate closed receptacles containing coloring products is provided, and includes a support plane which is configured to support a receptacle to be perforated. The support plane is movable in a substantially vertical direction. The perforation device also includes a perforation member positioned at a determinate height, higher than the support plane, and an actuator to selectively move the support plane toward the perforation member to cause the perforation of the receptacle to be perforated. The actuator includes a lifting mechanism connected to the support plane and drivable by a pedal that cannot be driven by an operator without the operator also driving a safety mechanism at the same time using both hands.

Abstract: Perforation device to perforate closed receptacles containing coloring products, comprising a support plane, movable in a substantially vertical direction and on which a receptacle to be perforated is suitable to be disposed, a perforation member positioned at a determinate height, higher than the support plane, and actuation means to selectively move the support plane toward the perforation member to cause the perforation of the receptacle to be perforated. The actuation means comprise a lifting mechanism connected to the support plane and drivable by means of a pedal from being driven by an operator without the latter also driving said safety mechanism at the same time and with both hands.

Abstract: A mixing machine for mixing a fluid product contained in a container, comprising one or more mixing devices, each able to mix the product according to a determinate mixing cycle chosen from a plurality of elementary mixing cycles. A command and control unit has a first memory in which the operating sequences of the plurality of elementary mixing cycles are memorized, and is connected to a data introduction device associated with a second memory in which the characteristics of the container or of the product to be mixed are memorized. Each operating sequence of the determinate mixing cycle is pre-defined according to the characteristics memorized in the second memory.

Abstract: Clamping device and method to temporarily clamp, in a mixing machine (11), a container (12) containing a fluid product, comprising two clamping elements (20, 21), opposite each other and able to clamp the container (12) in a determinate position. A movement mechanism (22), controlled by a control unit (24), is able to reciprocally move the clamping elements (20, 21) and impart thereto a clamping force (F) or clamping impulse, according to the actual height (L) of the container (12). The control unit (24) is also able to calculate, as a function of the clamping force (F), a relative clamping speed (v3), at which to move reciprocally the two clamping elements (20, 21) so as to clamp the container.

Abstract: An anti-rotation device for a gripping member of a mixing machine for fluid products contained in a closed container. The mixing machine comprises a fixed structure and the gripping member comprises a supporting structure rotary with respect to the fixed structure and on which two gripping elements are mounted, able to be selectively moved nearer to or farther from each other by means of a screw, in order to determine the temporary clamping of the container with respect to the supporting structure.
