Problems solved by technology

Firstly, movement of the closing element in the transverse direction between the closed position and the open position may lead to detachment of droplets of dye protruding from the lower end of the nozzle of the delivery head
Another disadvantage is that the seal between the closing element and the delivery head may be ineffective due to the inefficient transmission of force from the transverse direction of the closing movement to the direction coaxial with the delivery head
Furthermore, the clamping force pressing the gasket in the closure element against the lower edge of the delivery head may be uneven and a gap may form between the gasket of the closure element and the delivery head, which reduces the effectiveness of the closure device
Known closures can also suffer from difficult adjustments

Embodiment Construction

[0020] refer to figure 1 , numeral 10 denotes a dispensing machine configured to deliver metered quantities of various fluid products such as, for example, dyes for the preparation of paints. The machine 10 includes a raw material section 12 in which a plurality of containers (tanks) containing different fluid products (usually dyes) are housed. The containers are connected to corresponding conduits by means of corresponding dispensing pumps.

[0021] The conduits from the various containers of the machine 10 are connected to a delivery head 14 inside which a plurality of nozzles oriented in vertical direction are arranged and connected to the respective conduits. The nozzle of the delivery head 14 is enclosed in a tubular member 16 having an open lower edge.

[0022] The machine 10 includes a base 18 on which a container is placed and the dye dispensed by the delivery head 14 is poured into the container.

[0023] The dispensing machine 10 comprises closing means 20 for cl...

Abstract

A device for closing a delivery head of a dispensing machine for delivering fluid products comprises: a stationary support (22); a drive shaft (28), which rotates with respect to the stationary support (22) around a vertical axis (A), and can be moved with respect to the stationary support (22) along the same vertical axis (A); a cup-shaped closing element (24) carried at the distal end of an arm(26) fixed to a lower end (36) of the drive shaft (28); and a screw and nut mechanism (30, 50) which controls a translation of the closing element (24) in the direction of the longitudinal axis (A) and a rotation movement to the longitudinal axis (A) using a single actuator (58).

Description

technical field [0001] The present invention relates generally to dispensing machines for delivering fluid products such as dyes for paints and the like. [0002] More precisely, the invention relates to a device for closing a delivery head of a dispensing machine for delivering a fluid product. [0003] The invention has been developed for particular application in dispensing machines for the delivery of dyes for the preparation of paints. In the following description, reference will be made to this particular field without loss of generality. Background technique [0004] A dispensing machine for conveying dyes for the preparation of paints generally comprises a plurality of containers containing the respective dyes, which, in the case of so-called "simultaneous machines", are connected by means of corresponding conduits to Single delivery head. Multiple dispensing pumps supply metered doses of dye from containers to delivery heads. [0005] The delivery head typically...
