Brief Patent Description - Full Patent Description - Patent Application Claims
[0001]The present invention relates to a transfer device for sheet products, such as tissues, napkins and the like. BACKGROUND OF THE INVENTION [0002]The production lines of paper-like products, such as tissues, napkins and the like, of all sizes, are usually provided, predominantly in the final steps of the production process, with at least one drum, which rotates about its own axis and is provided internally with elements for providing a partial vacuum of appropriate value: said partial vacuum is adapted to retain, by way of appropriately provided openings, the products so that they adhere to its outer surface, so as to perform, in association with other elements, one or more folds according to a predefined order or in any case other final operations of the process. [0003]The products which adhere to the outer surface of the drum are usually then picked up by belt assemblies which convey them, on their upper portions, toward a station for stacking the products on each other for packaging in packs, said station usually comprising at least one star conveyor whose rotation axis is parallel to the rotation axis of the drum and which is provided with a plurality of peripheral receptacles in which the products are inserted and from which they are then deposited one by one on a movable supporting surface, which forms the stack which will then be packaged in a pack. [0004]The need is currently felt, for many reasons, to eliminate the step of conveying the products by means of the belt assemblies. First of all, the need is in fact felt to make production lines cheaper and constructively simpler; secondly, the need is felt to increase the transfer rate of the products from the drum to the star conveyor. SUMMARY OF THE INVENTION [0005]The aim of the present invention is to meet the mentioned requirements, by providing a transfer device for tissues, napkins and the like which allows to convey the products directly from the partial vacuum drum to the stacking star conveyor without the need for intermediate conveyor assemblies. [0006]Within this aim, an object of the present invention is to provide a device having a structure which is simple, relatively easy to provide in practice, safe in use, effective in operation, and has a relatively low cost. [0007]This aim and these and other objects which will become better apparent hereinafter are achieved by the present transfer device for sheet products such as tissues, napkins and the like, which comprises at least one drum which rotates about its own axis and is provided with retention means which are adapted to retain products such as tissues, napkins and the like so that they adhere to its outer surface along at least one portion of its rotation, and at least one star conveyor which is affected peripherally by a plurality of receptacles for the insertion of the products and for the release of said products at subsequent production stations, characterized in that it comprises at least one element for rotationally entraining the products one by one, which is arranged substantially between said drum and said star conveyor and is adapted to follow the insertion of each product within said receptacles. BRIEF DESCRIPTION OF THE DRAWINGS [0008]Further characteristics and advantages of the invention will become better apparent from the following detailed description of a preferred but not exclusive embodiment of a transfer device for tissues, napkins and the like according to the invention, illustrated by way of non-limiting example in the accompanying drawings, wherein: [0009]FIG. 1 is a perspective view of a transfer device according to the invention; [0010]FIG. 2 is a side elevation view of the device; [0011]FIG. 3 is a detail view of FIG. 2; [0012]FIG. 4 is a front view of the device; [0013]FIG. 5 is a bottom view of the device. DESCRIPTION OF THE PREFERRED EMBODIMENTS [0014]In the exemplary embodiment that follows, individual characteristics may actually be interchanged with other different characteristics that exist in other exemplary embodiments. [0015]Moreover, it is noted that anything found to be already known during the patenting process is understood not to be claimed and to be the subject of a disclaimer. [0016]With reference to FIG. 1, the reference numeral 1 generally designates a transfer device for sheet products, such as tissues, napkins and the like according to the invention. [0017]The device 1 is extremely versatile and is absolutely general in its application, since it can be used in production lines of tissues, napkins and the like having the most disparate characteristics. [0018]The products 2 processed by the device according to the invention can be constituted by tissues, napkins and the like of various sizes, with any arrangement of folds and with any number of plies. The materials of which said products are made also may be any, although usually they are paper-like or similar materials. [0019]The device comprises advantageously a drum, generally designated by the reference numeral 3, which rotates about its own axis and is associated with means for rotary actuation and is supported in fixed portions of the production line. For the sake of simplicity in understanding, the means for the rotary actuation of the drum and the fixed parts of the production line are not shown in the figures but are however of a substantially known and traditional type. [0020]The rotating drum 3 is provided with retention means, generally designated by the reference numeral 4, which are adapted to retain the products 2 so that they adhere to the outer surface 5 of the drum 3 along at least one portion of their rotation, as will become better apparent hereinafter.
