Definitions

  • the present invention relates to an evacuation device intended to be mounted downstream of the knife of a machine for splitting raw skins and capable of rationalizing the grouping of skins after slitting by allowing regular stacking according to a series of housed piles. inside a usual reception box, said device thus being able to reduce the manpower usually assigned to this type of operation.
  • the evacuation work may require two to four operators who must be perfectly accustomed to this function, which requires significant physical effort and also involves significant risks related to both hygiene and 'with accidents that may occur.
  • US Patent 3,163,032 has proposed a machine for transporting flexible sheets, for example skins or the like, which has a single, motorized extractor drum, with velocity of the primary means of feeding the skins and disposed downstream of the knife. skin cut.
  • Said machine cannot extract so-called tripe skins, which would be signed by the knife indelibly or in any way to the detriment of the finished product, but is ready to be used only with finished skins of small dimensions, for example for the use in shoes.
  • the machine described here has one or more series of crazy rotating toothed drums, arranged above the conveyor belt and which apply an adjustable pressure on the skin to be worked, according to the type of skin. .
  • the operation of extracting the skins treated by the slitting machine and depositing them inside the receiving box are rationalized and make it possible to reduce, if not to totally eliminate the qualified workforce assigned to this function, thereby eliminating physical effort and the risk of accidents.
  • the device according to the invention essentially comprises an extraction wedge which moves upwards the flower of the treated skins to bring it onto a conveyor belt equipped along its upper strand with toothed drums mounted on autonomous arms, which drums hold the skin applied against the aforementioned carpet according to a determined force provided for adjustable.
  • the conveyor belt brings the skins into the receiving box, with the possible interposition of a second extensible belt which is only used in the case where it is necessary to make several piles of skins inside large boxes.
  • the evacuation device is preferably mounted on a mobile carriage along rails in order to allow the device to be moved away from the slitting machine when it comes to carrying out the cleaning and handling operations thereof.
  • the low diagonal guide walls which hold the skins on the conveyor belt intended to bring them to the receiving box are provided with lateral guides equipped with rotating rollers with a vertical axis, this in order to allow the advancing skins without friction at their edges and thus facilitating the routing of these on the output conveyor.
  • a mechanism which makes it possible to apply a pressure force to the crazy toothed drums which guide said skins, by keeping them flat at the outlet of the slitting operation.
  • This mechanism comprises adjustment screws, each of which acts on a spring and which makes it possible to precisely adjust the above-mentioned pressure force as a function of the type of skins to be worked, an adjustable end-of-stroke screw being further provided for determining the maximum downward movement of the aforementioned drums relative to the conveyor belt.
  • the device is provided with two lateral receiving boxes as well as an additional conveyor belt arranged after the main conveyor belt but oriented transversely with respect thereto, this additional belt being capable of being controlled as well in one direction as in the other in order to discharge the skins in one or the other of the two boxes, thus conferring on the operator the possibility of moving away from the device that of which is filled and replace it with an empty one while the other continues to be charged.
  • the complete assembly comprising the conveyor belts 2 and 5 and the corresponding guide mechanisms is mounted on the carriage 7 on which the controls of the device are also provided; this carriage 7 moves on rails 8 which once the box 6 removed can be extended by rails 9, these being capable of pivoting along an axis 10 to be folded down to the position shown in broken lines in fig . 1.
  • the device also includes drums 12 and 13 intended to press the skin flower which rises on the conveyor belt 2 under the effect of the wedge 1.
  • the pressure force is adjustable within fairly wide limits thanks to adjustment screws 14 (fig. 4) mounted on plates 15 integral with the levers 16 which support the drums 12, said levers being articulated at 16 'at a fixed point of the device.
  • These screws 14 can penetrate more or less inside springs 17 mounted on fixed ears 18, thereby allowing to confer on the drums 12 an elastic pressure of well-defined amplitude, this pressure being adjustable.
  • a screw-like mechanism is associated with the levers 19 which are articulated at 19 ′ and which support the drums 13 of the second group, with an obviously identical result.
  • screws 20 provided with a locking nut provide an end of travel member for adjusting the height of the drums 12 or 13 above the conveyor belt 2.
  • each drum 12 or 13 is equipped with screws independent adjustment 14 and individual limit switch screws 20.
  • This arrangement makes it possible to arrange the skins, for example in the box 22 while the previously loaded box 23 is moved away from the device to be replaced by an empty box.
  • this arrangement allows uninterrupted operation by replacing the boxes as they are filled, without the need to stop the slitting machine 11 for this purpose.
  • transverse conveyor belt 21 and the longitudinal conveyor belt 2 are capable of being moved to the rear of the slitting machine, for example until reaching the position indicated in broken lines in FIG. 5, at the same time as the assembly supported by the carriage 7, this so as to allow the cleaning and handling operations of the machine 11.
