Definitions

  • the present invention relates to a device for introducing hides in tanning machines.
  • These machines usually have a rotatable work cylinder, suitable for obtaining, e.g., the cleaning, scraping, shaving, fluffing, polishing or perching of hides.
  • Another disadvantage is that usually the treatment of the hide occurs between the surfaces of two facing cylinders, the work area being thus greatly reduced, with the consequent necessity of performing more than one cycle to obtain an optimum degree of treatment.
  • the main aim of the present invention is to eliminate the above described disadvantages, by devising a device for introducing hides in tanning machines which allows the operator to perform his duties in safe conditions.
  • a further important object is to provide a device for introducing hides in tanning machines which adds to the preceding characteristic that of allowing an optimum and rapid treatment of the hide, simplifying its introduction phase.
  • Not least object is to provide a device for introducing hides which is structurally simple and can be applied to tanning machines of the known kinds.
  • a device for introducing hides in tanning machines having a rotatable work cylinder, which is characterized in that it comprises a traction roller and a movable belt which cooperate by means of preset control means, said movable belt being adjustable between separate free and parallel rollers, defining a continuous work area and providing a rest plane for a hide interposable between an operator of said device and said work cylinder.
  • the device 1 for introducing hides 2 in tanning machines 3 comprises a movable belt 4, preferably provided in antiskid plastic material, and maintained taut between three rollers indicated respectively with the numerals 5, 6 and 7.
  • rollers are advantageously identical, arranged parallel to each other and externally encased in a cylinder provided in elastically deformable material indicated with the numerals 5a, 6a and 7a.
  • rollers are freely pivoted at their ends to a frame 8 having means for adjusting the tension of the belt 4, these means being possibly composed of a tensioning element 9, which may comprise screw thread means or similar belt tension adjustment means.
  • a leverage 10 to the other end of which is pivotally coupled the corresponding end of a stem or rod of a piston or pusher member 11, the roller 5 being freely pivotally coupled and placed at the same height of the roller 6 to define an upper rest or resting plane 4a.
  • the stem of the piston 11 may be operatively connected to the frame by any suitable kinematic connection means, or alternatively, the frame may be fixed and the traction roller arranged to be moved towards the belt.
  • the operation of the piston 11 occurs by means of a control device composed of a bar 12, upwardly protruding transversely to the machine 3, said bar being adapted to be gripped by an operator, and the motion thereof controlling a preset solenoid valve.
  • a traction roller 13 is placed, to an end of which is keyed a hydraulic motor, this roller being pivotally coupled, proximate to the roller 6, to a compensator 14, having one end pivotally coupled to the frame of the machine 3 and an other end associated with a biasing means such as a spring 15, adapted for maintaining optimum contact engagement relationship between the surface of the roller 13 and the surface of the moving belt 4.
  • a biasing means such as a spring 15, adapted for maintaining optimum contact engagement relationship between the surface of the roller 13 and the surface of the moving belt 4.
  • such spring or biasing means may be provided with adjustment means for selectively varying the pressure imposed by the traction roller 13 on the hide 2 to be processed.
  • the device 1 is associated with the machine 3 so as to position the rollers 6 and 7 proximate to and facing the rotating work cylinder 16 which is usually present on these machines, the configuration of the cylinder allowing for the obtainment of various kinds of treatment, such as scraping, cleaning, fluffing, shaving, polishing, or perching.
  • the roller 16 will be provided on its lateral surface with a plurality of fins 17 which interact, during treatment, with the hide 2 placed on the belt 4.
  • the traction roller 13 can be made to rotate in one direction or the other, an operator being able to select the direction by acting on an actuation member such as a bar or rod 18, similar to the bar 12 but expediently located counterposed to it, protruding upwardly from the machine 3.
  • an actuation member such as a bar or rod 18, similar to the bar 12 but expediently located counterposed to it, protruding upwardly from the machine 3.
  • the use of the device 1 is thus as follows: once it is associated, as shown in the accompanying drawing figures with a tanning machine 3, initially the belt 4 will be placed in such a way as to not interact with the surface of the roller 13 or with the fins 17 of the cylinder 16.
  • the operator will proceed to position the hide 2 on the resting plane 4a and can then grip both of the bars 12 and 18.
  • the piston 11 By operating the first bar 12, the piston 11 will be actuated which, by means of the leverage 10, will bring the belt 4 in contact with the traction roller 13 and with the work area of the fins 17.
  • the operator By operating the lever or second bar 18 the operator will for example control the start up of the rotation of the roller 13 in the direction indicated in Fig. 4; the roller 13 engaging, in contact engagement relationship with the belt 4 according to a pressure which is adjustable by means of the spring 15, will thus transmit the motion to the belt 4 itself, pulling the hide 2 into contact with the work cylinder 16.
  • rollers 6 and 7 are adjacent to the work cylinder 16, a work area or plane 20 is defined between the rollers 6 and 7 which is continuous or flat and not point-shaped, thus permitting better and quicker treatment of the hide itself.
  • the operator can push the hide 2 in such a way as to perform the treatment of most of it, and subsequently he may reverse the motion of the roller 13 ( Figure 3), extracting the hide itself until it is positioned as illustrated in Fig. 2.
  • the hide 2 is pressed between the rollers 13 and 6 in such a way that the force imparted by the work cylinder 16 cannot pull it out, the cylinders 5a, 6a, 7a, and the belt 4 being provided in antiskid material, or similar material having gripping means, or properties such as a high coefficient of friction.
  • the invention has achieved all the aims proposed, as it is possible to associate the device with any tanning machine and in practice, by allowing the treatment of hides in conditions of absolute safety and tranquility for an operator, the device according to the invention inherently provides increased productivity.
  • the treatment of hides can furthermore be carried out very quickly whilst maintaining optimum work standards, since the operator can cause the movable belt 4 to advance as slowly or as quickly as necessary, thus keeping the hide 2 for presettable times in the work area 20.
  • the work area 20 being continuous, allows the correct cleaning or treatment of the hide in every point without any discontinuity whatsoever.
  • the belt 4 may be trained around more than the three rollers 5, 6, 7 illustrated, and the tensioning element may be of the automatic or self-adjusting type.
  • the materials and the dimensions of the components may be any, according to the requirements.
