Definitions

  • the present invention relates to the mechanical work of hides and skins and it relates, more particularly, to slitting machines, of the type with a blade driven in endless scrolling, perpendicular to the direction of progression of a skin, to ensure slitting, view of obtaining a leaf on the flower side and a crust, generally on the flesh side, which can also, in certain cases, be re-split again later.
  • Slitting is an operation which most generally takes place on skins in the initial tripe state or in the tripe state after pickling. This state corresponds to a treatment for moistening the skin, in combination with suitable salts to swell the skin and allow it to have a thickness sufficient to precisely perform its slitting.
  • a skin in the gut state has the particularity that it is in a relatively flexible state, making it difficult to take charge of, convey and guide to the cutting edge of the moving blade and exit of the machine.
  • an extractor device constituted by a bench carrying an endless conveyor or belt, called an evacuator.
  • This mat generally extending in a substantially horizontal plane, is capable of being engaged above the output table of a slitting machine.
  • the conveyor belt is associated, at the level of its front roller, with an extractor cylinder mounted at the end of an articulated arm and urged to be pinched on the belt by means of elastic members. .
  • the bench is mounted on rails adapted to the ground and whose length must take into account that of the useful carrier, in order to be able to bring the front roller of the latter in total clearance relative to the slitting machine.
  • This arrangement which is compulsory on the basis of the current structure, involves neutralizing a very large footprint behind the splitting machine, since it must be able to be used for engaging or disengaging, and conversely, of the extractor device. associated.
  • Such neutralization is, in particular, detrimental to the proper use of the useful area of the covered premises and involves bringing in the necessary structures to the guided movement, in one direction or the other, of the extractor device.
  • the object of the invention is to remedy the drawbacks noted above, by proposing a new extractor device designed to be permanently installed at the rear of a slitting machine by reducing, to the minimum value, the space required. ground permanently occupied.
  • Another object of the invention is to provide an extractor device capable of ensuring, in a permanently stable position, the engagement or release of extraction means with respect to the rear output table of a slitting machine , so as to offer complete access for carrying out cleaning, cleaning, blade change, adjustment, etc.
  • Another object of the invention is to provide an extractor device which is particularly designed so that its gripping spout can be engaged very deeply above the output table, so as to be located as close as possible to the cutting blade, in order to take charge and extract, as soon as possible, a split sheet.
  • the system extractor is characterized in that it comprises: - a substantially vertical frame intended to be placed near the rear facade of the slitting machine and delimiting a support, guiding and rolling track, - a chassis mounted on the track and connected to at least one drive member capable of moving it on the track from a high release position to a low working position in engagement above the output table of the slitting machine , - an evacuating belt carried by the frame and moved in the direction of progression of the sheet as regards its upper strand, - a separation sole carried by the chassis to extend, along the front edge of the chassis perpendicular to the direction of progression and to cooperate with the output table in the working position of the chassis, - And a set of extractor rollers arranged parallel to the top of the sole.
  • Fig. 1 shows a machine 1 for thickly slitting skins and leathers.
  • a machine comprises a frame 2 supporting, by guiding and driving means, a cutting blade 3 whose upper strand, the only one shown in FIG. 1 , is driven in scrolling in a direction perpendicular to the plane of the drawing.
  • a slitting machine as above, comprises, on the front face, an input or supply table 6 making it possible to present a skin flat on the plane PP ′ to bring it into the passage section between the rollers 4 and 5 , beyond which this skin is subjected to the action of the blade 3 .
  • a machine of the above type has a frame which delimits, on either side of the blade 3 , a corridor 7 for discharging the split crusts and an outlet table 8 on the rear facade, for guiding the split sheets towards a support system.
  • the output table 8 is located near the cylinder 5 and delimits, with the latter, a clearance interval 9 from which it is necessary to take charge of a slit sheet to assist in its tensioning and in its establishment promoting slitting. and extraction under suitable conditions.
  • the extractor device according to the invention is, precisely, intended to take care of such a sheet split in the interval 9 , automatically, by mechanical means which are described in the following.
  • the extractor device comprises a frame 10 , in the form of a gantry, mainly consisting of two uprights 11 joined by one or more cross members 12 .
  • the amounts 11 are intended for occupy a vertical direction and are anchored to the ground, so as to be located as close as possible to the rear cover of the machine 1 .
  • the supporting structure is characterized by a vertical orientation framework carrying, on a face facing the machine 1 , a guide track on which is movably mounted a frame having, beyond the rollers 16 , a front part in cantilevered.
  • This structure makes it possible to implant and permanently fix the frame 10 close to the rear face of a machine 1 and to be able to bring the chassis 14 , either in an engagement or working position, or in a release position. , without modification of the location of the frame 10 or relative displacement.
  • the front roller 22 is of small diameter and is completed, on the underside of the chassis 14 , by a roller 23 , called a tensioner, giving, in addition, to the lower section of the belt 20 a path along an inclined portion 24 , of the same angle than that of an inclined face 25 extending the output table 8 of the machine 1 .
  • the cheeks 17 of the chassis 14 carry, moreover, at their anterior end lugs 26 supporting a sole 27 , known as a detachment, intended to cooperate with the output table 8 .
  • the sole 27 extends parallel to the roller 22 , upstream of the latter relative to the direction of progression of a skin along the arrow f .
  • the legs 26 are adapted on the cheeks 17 , so as to allow an adjustment of the relative inclination of the sole 27 compared to table 8 .
  • the sole 27 is constituted by a rigid plate 28 of small width which is fitted to a stiffening angle section 29 connecting the tabs 26 .
  • the cheeks 17 of the chassis 14 support flanges 30 adapted from the front roller 22 and braced by a beam 31 .
  • the flanges 30 and the beam 31 support a set 32 of extractor rollers arranged parallel to each other and to the front roller 22 to be located above the sole 27 .
  • the assembly 32 comprises arms 33 mounted by means of pivots 34 , so as to be able to pivot in the direction of the arrow f1 .
  • Each arm 33 comprises a first end portion 35 , called the rear part, passing through the beam 31 and the movement of which is limited by an adjustable stop 36 and by an elastic absorber 37 with adjustable hardness.
  • the stop 36 and the elastic absorber 37 are preferably carried by the beam 31 and are arranged in opposition on either side of the edges of the terminal part 35 .
  • the arms 33 comprise, opposite the end portion 35 , each an anterior end portion 39 delimiting bearings for the support of at least two extractor rollers 40 and 41 , continuous or segmented, extending parallel to each other and to the roller 22 while being disposed above the sole 27 .
  • the rollers 40 and 41 are driven in rotation by means of a transmission 42 ( FIG. 4 ) taking its movement from a pulley 43 driven in rotation directly or by a transmission 44 , by an appropriate drive member 45 .
  • the roller 40 has axial grooves to facilitate handling and extraction, while the following roller 41 , with additional extraction function, is preferably provided with favorable helical grooves, when taking up in charge of the sheet, to an establishment of the latter by transverse stretching.
  • a sheet I split in the thickness from a skin p , is caused to climb the sole 27 according to the output table 8 and to be supported by the extractor roller 40 , before being able to be biased in transverse drift by the movement of the blade 3 .
  • the extraction action is completed by the roller 41 which acts in combination with the roller 40 , while proceeding, by means of its helical grooves, to establish the sheet I which can thus be taken in charge by the upper strand of the carpet 20 to be evacuated.
  • the roller 46 is provided so as to maintain the support of the sheet I when the rear edge of the latter is released by the roller 41 . In this way, the whole of the sheet is conveyed, in the direction of the arrow f en, being correctly supported by the upper strand of the belt 20 .
