Definitions

  • the present invention refers to a method and to a device for separating and conveying towards a packaging station a predetermined number of flat objects, such as strips or sheets of paper set down by a folding machine, such as a machine for forming table tissues. More in particular, the present invention concerns the separation and the transfer of strips or of sheets of paper during setting down or formation thereof to obtain in a mechanized manner packs comprising a predetermined number of table tissues or the like.
  • Manufacture of table tissues is currently done by means of folding machines, which essentially comprise two counter-rotating rollers, pushing means and a cutting blade.
  • the paper web reaching the rollers from the master roll is gripped by a gripper present on one of the counter-rotating rollers and pulled on the surface of the mentioned roller, up to a certain position in which the gripper releases its grip leaving a folded flap.
  • a similar gripper present on the other roller in turn performs a similar operation, forming an identical flap on the other side downstream from the pair of rollers and so on in succession, so as to put down flaps of paper one after another to the right and to the left downstream of the rollers to form a zigzag folded paper web.
  • Pushing means consisting of curved rods or the like are housed in appropriate recessed seats formed on the side surface of the rollers and are driven out of the seats after formation of each flap, moving the flaps away from the folded web to make room each time for the incoming new flap.
  • the pushing means press the flaps against a blade, which cuts the folded web in half, dividing it into two piles of table tissues side by side.
  • Separating devices are known in the form of fingers which are inserted into the pile of table tissues to separate a certain number of tissues so as to form a pack containing a small number of tissues which is picked up with appropriate grippers or tipped over on the plain of 90°.
  • this separating device proves inadequate for separating and in particular for picking up and for conveying a large number of tissues towards a packaging station for the formation of family-size packs, that is to say of packs containing a large number of tissues.
  • the operator in order to form family-size packs, the operator must manually separate and pick up the tissues in the packaging station with a resulting waste of time and of labour and a slowing of the production cycle of the machine.
  • Object of the present invention is to eliminate the drawbacks of the prior art by providing a method and a device for separating and for conveying towards the packaging a predetermined number of flat objects, such as sheets of paper, particularly tissues, that are able to automate and to speed up the production cycle of the packs of flat objects.
  • Another object is to provide such a method and such a device that are particularly suitable to be employed for the production of family-size packs consisting of a large number of flat objects.
  • Yet another object is to provide such a method and such a device that are highly versatile and suitable to be applied to various types of machines for the production of flat objects, such as sheets of paper, table tissues and the like.
  • Yet another object is to provide such a device that is inexpensive and simple to make.
  • the device for separating and for conveying towards a packaging station a predetermined number of flat objects, fed in piles from a folding unit comprises:
  • the racks are operated so as to separate a predetermined number of flat objects from a pile being formed, to form a pack between a pair of racks supported by a respective pair of carriages which are made to translate on their guides so as to convey the pack towards the packaging station.
  • the carriages of a pair can preferably be made integral with each other, so as to operate a single carriage to convey the pack comprised between the two racks supported by the two carriages.
