A conveyor device, in particular for an automatic packaging machine for paper rolls, having a horizontal plane of advance, at least one pair of motorized flexible transmission members extending along a closed loop and bearing a plurality of transverse bars fastened to said flexible transmission members, a plurality of thruster elements borne by said bars, and a stationary adjustment station provided with at least one adjustment assembly having a grip organ movable in transverse direction and arranged in such a way as to displace in the transverse direction along the respective bar a thruster element positioned at the grip organ.

Device and method for changing automatically the size of packs in a conveyor, in particular for an automatic packaging machine

A machine for applying partly adhesive straps to relative products has a folding device located between an input station, where the products are fed onto the machine, and an output station, where the products are fed off the machine; a feed device for feeding the straps successively to the input of the folding device; and a conveying device for feeding the products continuously along a substantially straight path extending between the input station and the output station, so that each strap is folded into a U about the relative product at the folding device.

Machine for applying partly adhesive straps to relative products

The apparatus is formed of two identical devices (A, A') installed mirror image-fashion, each of which is equipped with a pressure bar (&#x2032;) fitted to overhang the relevant lateral toothed conveyor belts (T, T&#x2032;) which move and recircle the sai bars, and which are in their turn activated by relevant motors (&#x2032;) with electronic speed and phase control governed by one programmable processing unit (). When the length of the products (P) is less than the length of the straight branches of the conveyors moving the said bars, the two devices are installed mirror-image fashion, with the axles of the pulleys of one conveyor aligned with those of the corresponding pulleys of the other conveyor. In this position, the bars (&#x2032;) of the two devices alternate in taking, moving foward by pushing and the final placing of the product in the workstation (K). However, when the length of the products exceeds the length of the said conveyors moving the bars, the possibility is offered of acting on both means, allowing anticipation of the longitudinal position of one device in relation to the other, so that the products are firstly taken by the bar (&#x2032;) of device (A&#x2032;) working in advance and are transferred from it in phase to the bar () of the downstream device (A), which in turn provides for the transfer and phased placing of the product in the workstation (K).

Device to modify the pitch between pushers according to the length of the product

The thrust bars (), which are placed behind the product in the transfer phase from a first transport line (L) to a downstream line (L), have an adjustable stop () resting against the one side of the product in the direction of travel of this product. Articulated joints ('), connect the ends of the bars to corresponding points of the upper branch or the lower branch of a parallel pair of toothed belt conveyors (T, T&#x2032;) fed on pulleys with horizontal axles, which are inclined at a right angle to the conveyors (T,T&#x2032;) which bridge the area between the two transport lines and which with their one branch, work in the direction running from the upstream line to the downstream line at an identical speed to each other such as to be able to effect, with the above-mentioned bars, the transfer of products from one conveyor belt to the other by rear and side thrust. Guides (&#x2032;) are provided parallel to the conveyor (T) connected to the outer edge of the junction area of the conveyor lines to guide the right-hand edge of the product in the working direction during the transfer phase, particularly when this product is very long.
