摘要:
There is described a conveyor for an article handling unit, comprising an endless transport element fed with a plurality of articles at an input station and advancing the articles along a handling path to an output station; the transport element is formed by a plurality of modules, each comprising a supporting member adapted to receive in use a relative article to be handled; each module further comprises a rotating element mounted in a rotatable manner onto the supporting member to produce a change of orientation of the relative article before to release it at the output station.

A forming member for controlling the volume of packages of pourable food products formed from a tube of packaging material and sealed at a number of sections of the tube crosswise to an axis of the tube; the forming member having: a main wall which cooperates cyclically with a first portion of the tube extending between two consecutive sections; and at least one flap extending alongside the wall. The flap is movable, with respect to the wall, between a first position, in which it cooperates with a second portion of the tube, extending between the two consecutive sections, to control the volume, between the two consecutive sections, of the package being formed, and a second position, in which it is detached from the second portion.
摘要:
A folding unit for producing packages of pourable food products from sealed packs having at least one projecting foldable end tab. At least one conveying member cyclically receives a relative pack, by the end corresponding to the tab, and feeds the pack along a forming path crosswise in the axis of the pack. A folding mechanism having an impact surface receives each pack by the end corresponding to the tab, and is carried by the conveying member to move between a first operating position, in which the impact surface forms, with the feed direction of the relative pack, an angle of over 90° and open in the direction of the forming path, to fold the relative tab, upon impact, onto the pack in the traveling direction of the pack, and a second operating position, in which the impact surface is rotated towards and cooperates with the pack.

摘要:
Pump units comprising a metering reciprocating pump with adjustable length of stroke are used in packing machines for filling of packing containers with a metered quantity of flowable contents, e.g. yogurt. Adjustments in the length of stroke in order to adapt the amount of filling goods to the volume of the packing container interferes with the breaking sequence at the extreme position of the piston and alters the time for each pumping stroke. These drawbacks are avoided by means of an arrangement which includes a movable braking device for the piston as well as a valve arrangement which is linked to the braking device and serves to adapt the speed of the piston to the length of stroke.
