Definitions

  • This patent for an invention concerns a grip conveyor for jumbo rolls of paper and other products or containers which have two parallel sides.
  • this grip can be attached to the tackle or hooks of a crane for the movement of large coils of paper within factories, or for loading onto vehicles, trucks and other means of transport.
  • the grip is furnished with a mechanical device which facilitates its implementation.
  • the machine consists of two lateral, flat support panels which grasp the sides or base of the rolls. There length can be regulated by means of a regulator screw system (a handle turns a screw which simul ⁇ taneously alters the length of each panel) furthermore, these panels are linked by levers on the top supporting cross-bar and the single hook which supports the whole grip.
  • the side panels are united to the top cross-bar and slide to take the load on the inner part so governing their regulation and rigidity.
  • the levers are co-ordinated in orde to indirectly link the hook to the pressure lifting panels, so that when the load is raised the panels move towards each other by interaction of the levers and the weight of the loa
  • the safety mechanism depends on the movement of the levers and their position in respect to the frame during the operative cycle. In fact, this mechanism is centrally positioned on the machine and consists of a cogwheel with eight positions unified to a ring-nut with four protruding sections.
  • the cogwheel is moved by opposite striker-plates or stops on the fixed part of the machine therefore the ring-nut also moves, it is positioned centrally at the intersection of the two levers, so as the height changes during the phases of operation the cog strikes against a striker plate and turns by an eighth of a cycle.
  • the cogwheel and ring-nut are positioned on the moveable part of the machine and slide along a bar next to the ring-nut, which has two perpendicula notches (their distance is equal to the diameter of the ring-nut) and is fixed to the stable cross-bar of the machin
  • the two grooves on the vertical bar, working in conjunction with the ring-nut are funtamental to the smooth working of the grip at any phase and position of the operation.
  • the load When the optimum pressure has been reached for holding the drum of paper, the load is ready to be lifted and moved.
  • the weight of the load pulling against the levers works in unison with the hold of the grip, to ensure a safe carriage without any risk of accidental release.
  • the machine lowers the product and simultaneously the gripper panels release it; the wheel turns and the ring-nut lodges into the grooves of the centra bar, locking the panels into the open position; at this point the machine can be used for the succeeding operation.
  • the machine can also simultaneously transport two drums of paper, side by side, this can be done automatically where the products are of equal length, simply by lowering and lifting the grip, but where the dimensions vary, an operator will have to regulate the opening of the gripper panels. This can be done manually with the regulator handle and screw or other automatic methods can be added, for example an electric motor, etc...
  • the two plates inclosed illustrate an example, but in no way limiting, design of the invention:
  • - Fig.1 shows a perspective view of the grip conveyance with a load of two paper drums
  • Fig.2a shows a front view of the wheel assembly for the automatic.mechanical lever system for locking the machine in position
  • FIG.2b a side view of figure 2;
  • - Fig.2c shows the grip over a jumbo roll in a reduced scale
  • - Fig.3a shows a schematized front view of the wheel assembly in a locked position, after the ring-nut has turned in order to grip load
  • - ig.4b shows a side view of Fig.4a
  • the design of the machine comprises of one unmoveable part (1) that is, a bar along which the gripper panels run and on which two levers are counter-balanced (2) & (2.1) these operate the panels indirectly (3) & (3.1) by means of the symmetrical adjustable spacer (4) & (4.1).
  • the levers (2 & 2.1) on the top arm are counterbalanced on a rod (5) support by a hook (6).
  • a vertical, grooved bar (7) with two notches (8) is attached to the central unmoveable part of the machine; this runs through an external support (9) on which there is cogwheel (10) fixed to a ring-nut (11) with protruding teeth (12) set at a perpendicular angle to rotation axis .
  • the rotation of the ring-nut depends on the motion of the cogwheel (10); this occurs only when the machine rests on its own weight, either on a load or on the floor; this conta sets the teeth in motion by an eighth of a cycle at a time until the teeth of the ring-nut are positioned in apposite grooves (8) .

Abstract

Un transporteur par serrage pour rouleaux géants de papier et autres produits, ou pour des récipients ayant deux côtés parallèles, se caractérise par le fait qu'il utilise deux leviers contrebalancés (2, 21) soutenus et actionnés par une traverse (1) et par un crochet central (6) qui, à leur tour, actionnent deux panneaux, ou pinces (3, 31) qui se rapprochent en exerçant un effet de serrage lorsque le crochet (6) est soulevé. En outre, un système de blocage d'une position "ouverte" est actionné par une roue dentée (10) fixée à une virole (11) avec des dents (12) qui enclenchent des rainures d'une barre verticale (7).
