Definitions

  • the present invention relates to a method for successively wrapping up one flat object at a time, more particularly a stack or a ream of paper, as Well as to an apparatus for carrying out said method.
  • the invention renders it very well possible to satisfy these requirements if a web of packing material is laid against the lower side of said object as said object is being relatively transferred from a first supporting element to a second supporting element, which elements are spaced by a slit, said packing material being pulled through said slit and being progressively and simultaneously laid against the lower side of said object and on the upper side of said second supporting element.
  • An apparatus which according to the invention renders it possible to carry out this method is characterized by the combination of a table formed by two jointly reciprocatory sections between which there is interposed at least one guiding means for guiding a Web of packing material, first holding means so mounted as to be stationary relative to the frame of the apparatus and second holding means so mounted as to be stationary relative to the movable table, said first and second holding means being adapted to alternately hold the end of the web of packing material, a severing device for periodically severing a terminal length from said web of packing material, as Well as displacing means for displacing the object to be wrapped up relative to the table, at least one of said displacing means being adapted to be periodically moved up and down.
  • FIGURE 1 is a plan view of a portion of the apparatus
  • FIGURE 2 is a side view of the apparatus in the position according to FIGURE 1;
  • FIGURE 3 and FIGURE 4 are each a side view of a different operative position
  • FIGURE 5 is a single detail of the severing device
  • FIGURE 6 is a cross sectional view of a portion of the table adjacent the severing device and one of the holding means.
  • the supply end of the apparatus is provided with a table 1, pushing means 2 and 3 respectively, by means of which successively reams of paper can be pushed to the centre of the table, from which place they are further fed through the apparatus by a pushing means 6 which is moved along the frame beam 5 by means of a source of power 4.
  • a table comprising the sections 7 and 8 is so mounted on the frame of the apparatus as to be reciprocatory.
  • a set of vertically movable spaced apart displacing plates 9 and 10 is so mounted as to be adjustable in longitudinal direction, a cutting wheel 11 being provided between said plates, which roller is adapted to reciprocate transversely to the direction of feed of the reams, during which reciprocatory movement said cutting wheel is adapted to cooperate with a shear blade 12 when the table is in its one final position.
  • Blade 12 is connected with and in consequence moves along with said table.
  • the shear blade 12, vide FIGURE 5 is provided with bevel sides 13 and the rolling blade 11 is mounted resiliently so as to be slightly movable in a direction transversely to the shear blade and about an axis transversely to said shear blade 12.
  • a reversing roller 14 for reversing the direction of movement of the web of packing paper 15 is mounted for movement along with said table, which web via stationary rollers 16 and a weighted roller 17 is drawn off a supply roller 18, or, especially in the case of rapidly running machines, is positively supplied intermittently.
  • the web 15 has its leading end engaged by clamping elements 1h that are adjustable in transverse direction and that are adapted to be tilted over, whereupon the table, as seen in the drawing, will move towards the right, during which movement via the roller 14 a terminal length of the packing paper will be laid on top of the table section 7.
  • the table section 7 moves on over a slight distance in order to transfer the ream of paper lying on the severed piece of packing paper to the further packing means which may be of a relatively arbitrary nature.
  • the brake shoe 20 has been released again and the clamping elements 19 have engaged the new end of the packing paper that has come within their reach and after the displacing means 9, 10 have moved down again, a same cycle will start for wrapping up the next ream of paper.
  • the means for actuating the various elements mentioned may be of a pneumatic, electro-magnetic or of another nature. They are naturally operated in a suitable timed relationship and will not be further described hereinafter.
  • the elements which displace or arrest the reams of paper are adjustable in view of the variations in the dimensions of the reams.
  • the means for effecting said adjustments are not of very particular nature and accordingly they have not been further shown in the drawings.
  • the rolling blade 11 together with its supporting construction is connected to the table 1 which is longitudinally adjustable, so that the displacement of this table is always equal to the displacement of the rolling blade in the case of adjustments in longitudinal direction. This is also decisive for the working stroke of the table 7, 8.
  • a resilient strip which is flush with the table top is located opposite saidblade.
  • a packaging machine for packing successive stacks of paper sheets insheet wrapping material comprising a frame, two table portions mounted on said frame spaced from each other to define a slit between them, said table portions having substantially horizontally extending stack supporting surfaces thereon and being connected to each other for movement back and forth along said frame, guide means mounted in said slit for guiding a web of Wrapping material through said slit, clamping means fixed relative to said frame and positioned at a point adjacent said slit when said table portions'are at one end of the back and forth movement, said clamping means being adapted to clamp the edge of a web of Wrapping material and hold it while said table portions are moved, cutting means at least part of which is positioned above said table portions adjacent said slit when said table portions are at the other end of the back and forth movement and adapted to cut the web of wrapping material, and an arresting means movable up and down above the table portions at a point adjacent said cutting means, whereby when said table portions are at one end of the back and forth move: ment and the end of
  • said guide means is a guide roller having a circumferential surface 4 and rotatably mounted on said table portions and movable therewith.
  • said guide means further comprises at least one brake shoe mounted on one of said table portions and movable into engagement with the circumferential surface of said rotatable roller.
  • said cutting element is an elongated shear blade countersunk into thetop of one of the table portions and at least one part of said cutting means above the table portions is a rolling blade movable transversely of the direction of movement of said table portions.
