Definitions

  • the present invention relates to a device for transverse bending, transverse cutting both by pressure and in scissors mode, and vertically piling and transporting the piles in automatic mode of products obtained with materials suitable for this work process, such as: non-woven fabric, spunlace, tissue, paper in general, plastic materials, drylaid etc., both dry and soaked.
  • the object of the present invention is to provide an improved assembly for the manufacture of a product, which can operate safely and reliably at higher production rates than prior art assemblies.
  • the assembly 10 comprises a stationary structure including two vertical walls 12, parallel to each other, which support the rotatable parts of the machine.
  • the strips 14 constitute the starting material for the manufacture of these products.
  • Said strips are collected in continuous form in rolls or coils (not shown), wherefrom unwind the segments of strip that are fed to the assembly 10 to form the product.
  • the strips 14 can be constituted by non-woven fabric, tissue paper or any other material suitable for this kind of production (handkerchiefs, table napkins, etc.).
  • the assembly 10 comprises an inlet section formed by the cylinders 22, a cutting unit 18, a bending and transfer cylinder 20 and a station for forming product packs, designated by the reference 54 in Figure 2.
  • the inlet section comprises two feeding rollers 22 whose purpose is to feed the strip 14 in the longitudinal direction at a constant rate.
  • the strip 14 Downstream of the feeding cylinders 22, the strip 14 enters the cutting unit 18 which comprises a cutting cylinder 24 and an abutting cylinder 26.
  • the cutting cylinder 24 bears a plurality of cutting blades 28 equally distanced from each other along the perimeter of the cylinder 24.
  • the abutting cylinder 26 bears a plurality of abutting blocks 30 equally distanced along the perimeter of the cylinder 26.
  • the cylinders 24, 26 rotate in phase with each other so that each cutting blade 28 at each revolution comes in contact with a respective abutting block 30 in order to execute a cut in the transverse direction of the strip 14 that passes the cylinders 24, 26.
  • the segments 14a remain adherent to the surface of the abutting cylinder 26.
  • the abutting cylinder 26 is preferably provided with a plurality of inserting members 32 each of which has the shape of a blade or of a comb with an end that projects slightly beyond the outer surface of the cylinder 26.
  • the outer surface of the cylinder 20 is substantially tangential to the abutting cylinder 26.
  • the bending and transfer cylinder 20 comprises a plurality of pincers 34 equally distanced from each other along the perimeter of the cylinder.
  • each pincer 34 is rotatable around its own axis relative to the cylinder 20 and it is fastened at each of its ends to an actuating lever 40 that actuates the oscillation of the shaft 38 around its own longitudinal axis.
  • the pack forming station 54 comprises a pan 56 movable in the vertical direction, whereon are piled the products that are detached from the bending and transfer cylinder 20 in the way that will be described hereafter.
  • a control unit commands the progressive lowering of the pan 56, as a function of the rotation of the bending and transfer cylinder 20.
  • the detaching device 58 comprises an oscillating element 60, provided with arms 62 capable of entering respective grooves 64 formed in the cylinder 20.
  • the oscillating element 60 detaches a piece of product 14a from the cylinder 20 and deposits it on the pan 56 or at the top of the pile formed by pieces previously deposited on the pan 56.
  • the actuating mechanism also comprises a pneumatic actuator 74.
  • the oscillating element 60 oscillates downwards, detaching the product from the surface of the cylinder 20.
  • the product is deposited on the upper surface of the pan 56.
  • Figures 4 and 7 respectively show the two extreme positions of the oscillation travel of the oscillating element 60.
  • the actuator 74 is activated and it raises the oscillating member 60 in advance with respect to the normal operating cycle to enable the evacuation of the pack P by a conveying member 80.
