Definitions

  • the present invention relates to a footboard, especially for winding machines, and a winding machine provided with such footboard.
  • the present invention is apt for use in the paper industry and industrial machines for the treatment and production of web materials such as paper, cardboard, tissue paper, nonwoven fabric.
  • the present invention can be utilized for the winding, cutting, coupling and stocking of the above mentioned material.
  • the above machines include a plurality of support and/or guide rollers which define a feeding path provided with access spaces and/or windows for the operators that have to control and operate directly on preset machine's areas such as the blades region, for example, in correspondence of which the cutting means are predisposed as necessary for sectioning the continuous web.
  • the blades region is provided at such position as to allow an easy access for the operators, even if this entails a tortuous and detrimental path for the web material.
  • the Applicant has found that the known machines cannot be improved under many points of view, mainly in relation to the integrity of the continuous paper web and to the accessibility of some operating areas which are interested by periodic inspection and service interventions.
  • the object of the present invention is therefore to propose a footboard, in particular for winding machines and the like, and a winding machine provided with such footboard and able to maintain the structural integrity of the feeding material while facilitating the inspection and maintenance of one or more machine's regions.
  • numeral 1 indicates on the whole a footboard, especially for winding machines, according to the present invention.
  • the footboard 1 is associated with a winding machine 2, typically employed in the industrial sector of the manufacturing and treatment of web material.
  • the winding machine 2 comprises a support structure 3 for sustaining roller means 4 predisposed for feeding at least one continuous web of paper material along a path "P" of predetermined advancement.
  • the roller means 4 include a plurality of support and/or guide rollers 4a mainly distributed along a lower portion 2a of the machine 2.
  • the feed and/or guide rollers 4a drive the continuous web 5 coming from a supply station (not shown as being well known) to a winding region in order to form a reel 6 in correspondence of an upper portion 2b of the machine 2.
  • the continuous web 5 is wound on the reel 6 which, upon completion of the winding, is transferred to a suitable storage or treatment region (not shown).
  • the machine 2 exhibits an operational region, also called “blades region” where a set of cutting elements are located (not shown as being well known) to carry out the sectioning of the feeding material.
  • an operational region also called “blades region”
  • a set of cutting elements are located (not shown as being well known) to carry out the sectioning of the feeding material.
  • Predisposed above the operating region 7 are one or more control areas 8 which can be accessed by an operator through the said footboard 1.
  • the footboard is provided with at least one support element 9 that can be associated with the machine 2 in proximity of the operating region 7 and control areas 8.
  • the footboard 1 is provided with one or more support elements 9, preferably consisting of bearing columns 10, fixedly engaged to the base 11 on which the machine 2 rests.
  • the footboard 1 is also provided with at least one suspended walkable surface 12 operatively engaged with the bearing columns 10.
  • the walkable surface 12 is preferably located above an initial length "I" of path "P" of the continuous web 5 so as to make the latter advance without interfering with the work of the operators.
  • the walkable surface 12 exhibits at least one segment 12a which defines a bearing plane 12b for one or more operators who have to easily reach the overhanging control areas.
  • the segment 12a is movable between a work position - in which the bearing plane 12b is disposed close to the operating region 7, preferably in a substantially horizontal lying plane (Fig. 1), in order to bear the operator during one or more work procedures - and a disengagement position (indicated with dashed line in Fig. 1) in which the bearing plane 12b is spaced from the operating region 7 to allow access to one or more sectors of the latter, as necessary to carry out periodic inspections and maintenance interventions which are normally hampered by the walkable surface 12 when the segment 12a is in the operating position.
  • the solution shown in the attached figures provides for the segment 12a to engage at least one respective column 10 by at least one hinge constraint 13, so as to allow the segment 12a to rotate about a respective, preferably horizontal axis of rotation "X" extending substantially parallel to the longitudinal development of the feeding and/or guiding rollers 4a of the machine 1.
  • the segment 12a On the opposite side with respect to the hinge constraint 13, the segment 12a has its free edge 12c facing the machine 1 when the walkable surface 12 is in work position.
  • the columns 10 - or any other type of support element 9 being provided - have preferably at least one housing space (not shown) to receive the segment 12a of walkable surface 12 when the latter is in disengagement position, as represented with dashed line in Fig. 1. In this way, when the walkable surface 12 is in the disengagemet position, it remains at least partially embedded inside the columns 10, without occupying the space interposed between the latter and the same machine.
  • the walkable surface 12 preferably exhibits three segments 12a, each movable as above described between the work and the disengagement positions.
  • each segment 12a can be caused to rotate about the axis of rotation "X" independently of the other segments 12a, so as to allow the operator to have access only to some parts of the machine 2. It is understood that, the moment it results necessary to clear the whole space taken by the walkable surface 12, all the segments 12a are moved to the disengagement position, either at the same time or in sequence, by suitable actuation means not shown.
  • the machine 2 is provided with a plurality of bearing shoulders 2d for engaging at least a relevant segment 12a of the walkable surface 12 when the said segment is in work position.
  • two bearing shoulders 2d of the machine 2 are made to correspond which operate in correspondence of the end corners 12d of the respective free edge 12c.
  • each bearing shoulder 2d exhibits a bearing surface suited for supporting two segments 12a at the same time.
  • the present invention overcomes the problems of the known technique and achieves the proposed objects.
  • the footboard according to the present invention allows the operators to have access to both the control region disposed above the machine and the operating or blades region disposed in correspondence of the rest base of the same machine.
  • the change from an operating condition, in which the operators can transit on the walkable surface and work on the lower part of the machine, to a disengagement condition, in which the operator can have access to the blades region without any obstacle and interference, results simple to carry out.
  • the segments involved are driven into rotation in counter clockwise direction through an angle of about 90° thus lifting the respective free edge.
  • the transition from the condition of disengagement to the operating one is performed by a rotation of the involved segments in clockwise direction through an angle equal to that previously covered.
