    • B08B9/426—Grippers for bottles

Definitions

  • the present invention refers to a pusher for operating gripping pliers or the like in a rinsing machine.
  • the rinsing machine in question is preferably a bottle rinsing machine or a machine for rinsing other containers showing a similar shape.
  • the rinsing machines or machines for treating and cleansing bottles consist in general of a rotating roundabout the peripheral part of which is provided with pliers which grasp the bottles from a zone of introduction, hold them upturned during the treatment and release them in a zone of collection from which the bottles are taken for the subsequent phases such as the filling phase.
  • the said gripping pliers comprise in general two jaws which are pivoted specularly in respect to their axis of symmetry.
  • the jaws may be opened or closed to grip or release the bottles by means of a sliding block drive system which turns the rectilinear motion imparted by a cam into the angular motion of the jaws.
  • the cam exerted a thrust function directly on the sliding block arranged on the gripping device formed by the pliers.
  • the said system involved some inconveniences such as the inconveniences due to a certain wear of the mechanical parts and to the impossibility of cushioning the movements and there were possible anomalous thrusts and excessive or insufficient tensions for a correct grasp of each single bottle.
  • the aim of the present invention is to eliminate the above described inconveniences and further consequent inconveniences and in particular to conceive and carry out a particular device which is able to absorb all the mechanical stresses due to the use of a cam as actuating element for opening and closing the bottle gripping units in a rinsing machine or the like.
  • the present invention proposes further that the wear of the sliding thrust block may be eliminated or at least reduced. At the same time, any mechanical deformation is prevented in the whole gripping pliers.
  • a pusher- damper for actuating gripping pliers or the like which are arranged in a rinsing machine, such a device being preferably interposed between a pressure pad of gripping pliers and the relative actuating cam, characterized by the fact of consisting of a hollow cylinder which is arranged in axis and/or parallel with the axis of symmetry of the pliers, a piston or pushing element slides in the inner chamber of the cylinder and is arranged in antagonism with a spring , the piston or pushing element is provided with a pivot carrying a roll or the like which may be intercepted by an actuating cam; the front part of the said piston or pusher protrudes from a suitable opening which is provided on the cylinder head and may be connected with the said pressure pad so as to turn the rotatory or transversal movement of the said cam into a linear movement of the pressure pad itself to permit the opening and/or closing of the pliers
  • number 1 denotes a pushing-damping device on the whole according to the present invention.
  • the device in question is arranged at gripping double-jaw pliers 2 equipped with a sliding block or pressure pad 3.
  • the pusher-damper 2 consists of a cylinder 4 which comprises an inner slide chamber in which a piston or pushing element 5 slides and is arranged in antagonism with a spring 6.
  • the unit cylinder-piston is arranged on the axis of symmetry of the gripping pliers or parallel to the pliers.
  • a pivot 7 is vertically pivoted in the rear part of the piston 5 and is able to support and rotate a roll 8.
  • the fore part of the piston 5 projects from an opening obtained in the cylinder head and pushes the pressure pad 3.
  • the pressure pad 3 is equipped with a backing plate 9 which is arranged and fixed on the rear part of the pressure pad.
  • the backing plate 9 is made of a high-resistance metallic material and increases the resistance of the pressure pad against the thrust stresses impressed by the piston 5.
  • the roll 8 is interested by a transversal thrust which is impressed by a cam (known and not represented).
  • the roll 8 absorbs such a thrust and transmits the same to the piston 5 which is constrained in the cylinder 4 which acts as a guide.
  • the piston 5 in its turn exerts an axial force on the pressure pad 3, which is protected by the backing plate 9, and provokes the opening of the gripping pliers 2.
  • the above described device may be compared with a mechanical damper since the piston and the cylinder are coupled in such a way that the spring arranged in the inner part of the cylinder brakes the opening speed of the device and permits the device to return to the rest phase.
  • the same function of the spring 6 may be accomplished also in a pneumatic way.
  • the piston may be realized as an airtight piston and calibrated holes 10 may be made in the cylinder.
  • the damping action of the described mechanical and/or pneumatic device may be adjusted by interchanging different types of spring in the device itself or by dimensioning the calibrated holes 10 in a suitable manner.
  • both jaws of the pliers 2 show two contrivances which make the functionality of the pliers easier.
  • the first contrivance consists of anti-friction washers 11 which are arranged on pivots which provoke the opening thrust of the jaws, such washers permitting a better advancing and an easier guided opening action.
  • the second contrivance consists of an auxiliary spring 12 which keeps both jaws in their respective positions during all their operative phases and improves the functionality of the jaws since this contrivance eliminates any possible clearances or the small slacks of the jaws.
