  • ABSTRACT Blunk Assistant ExaminerRobert Saifer Attorney, Agent, or Firm-Holman & Stern 5 7 ABSTRACT A tilting suction device for lifting objects having a flat surface in which the bellows is peripherally pleated over its entire length; one diametrical half having an axial rigidity differing from that of the other diametrical half so that when evacuated, it will assume an angularly inclined condition to reorient the object being lifted and/or the pleated bellows is permanently inclined and is introduced to an object being lifted in an inclined condition and when evacuated assumes an inclined condition to reorient the object being lifted.
  • the invention relates to a tilting suction device for lifting objects with flat top surfaces, in particular sheets of paper, said device having a liftable, inclinable suction cup connected to a nipple of a vacuum suction pipe.
  • the suction cup is a rigid element which, after aspirating a sheet by the vacuum action, can be swivelled about a pivot, against a spring, into an inclined position, from which, after removal of the sheet, it is pressed back into its original position parallel to the top surface of a stack of the sheets by the action of the spring.
  • Another known tilting suction device comprises an elastic suction cup, the axis of which is inclined at an angle to the object to be lifted, so that the edge of the suction cup positioned in a plane approximately perpendicular to the suction cup axis during the lowering process, on one side comes into contact with the object to be lifted.
  • the remainder of its edge also comes into contact with the object to be lifted.
  • the object of the invention is to provide a tilting suction device which operates without mechanical moving parts.
  • a tilting suction device for lifting objects with flat top surfaces comprising a liftable inclinable suction cup connected with a nipple of a suction pipe, the suction cup being placed at one end of a bellows, of which the other end is attached to the nipple of the suction pipe, and two diametrically opposite halves of the said bellows having adifferent axial spring rigidity respectively.
  • a tilting device for lifting objects having flat top surfaces comprises a liftable, inclinable suction cup connected with a nipple of a suction pipe, the suction cup being connected to one end of a bellows connected at its other end to the nipple of the suction pipe, the said bellows having approximately the same axial rigidity over its complete periphery, and the suction cup being inclined.
  • the elastic material of the bellows is thicker on the one half than on the other.
  • the bellows is connected with a vacuum source through a throttle which is provided on the end of the bellows opposite the suction cup.
  • FIG. 1 shows a first alternative form of tilting suction device, in axial section, with the bellows expanded
  • FIG. 2 shows the tilting suction device according to FIG. 1 in elevation, with the bellows contracted
  • FIG. 3 shows a second alternative embodiment of tilting suction device in axial section, with the bellows contracted, and with a lifted object
  • FIG. 4 shows the tilting suction device according to FIG. 3, in elevation, after deposition on the article to be lifted.
  • a nipple 1 of a suction pipe 2 which is connected to a vacuum source and serves as a support, one end 3 of a bellows 4 is firmly attached.
  • a throttle 5 is located in the nipple 1.
  • the opposite end of the bellows 4, is shaped as a suction cup 6.
  • the opening 7 of the bellows 4 has a substantially larger cross-section than the opening 8 afforded by the throttle 5.
  • the left hand half of the bellows 4 shown in the drawing has a thicker wall than the right hand half. Since the material of the be]- lows 4 is elastic, that is for example, it is made of rubber or plastic, a different spring rigidity in the axial direction is obtained for the two halves of the bellows 4.
  • This differing contraction causes the edge of the paper sheet 9 picked up by the device, to become inclined, so that between the sheets of the stack 10 and the lifted sheet of paper 9, a wedge-shaped gap is produced, into which, for the purpose of lifting the sheet 9 away from the stack 10, air may be blown in the direction of arrow 11.
  • the sheet of paper 9 can then be removed laterally from the stack 10 on an air cushion.
  • FIGS. 3 and 4 differs from that illustrated in FIGS. 1 and 2, in respect of the bellows 14 and the suction cup 16.
  • the axial rigidity is constant over the entire periphery of the bellows 14. This is achieved by using identical material and identical wall thickness over the entire periphery. Because of this design, the suction cup 16, during lowering of the tilting suction device, meets the uppermost sheet 9 on the stack 10 with one side. With continued lowering, the entire edge of the suction cup 16 comes into contact with the uppermost sheet, the bellows 14 being more strongly compressed on one side than on the other.
  • the first alternative solution is more advantageous in many respects compared with the second. Firstly, the space between the top surface of the object to be lifted and the suction cup, with the bellows expanded, can be kept very small, which allows a small stroke and the resulting possibility of rapid movement. Furthermore, in the first alternative solution, during the deposition of the device, no transverse thrust relative to the direction of deposition is produced, as the suction cup is simultaneously deposited with its entire edge. However, in the second alternative solution, there is essentially a transverse thrust relative to the direction of deposition, which effects displacement of the sheet of paper to be lifted, and leads to increased abrasion of the edge of the suction cup. In addition, a greater stroke is necessary for the suction cup to be sealed by complete contact with the surface of the object to be lifted.
  • a tilting device for lifting objects having flat top surfaces comprising a liftable, inclinable suction cup connected with a nipple of a suction pipe, the suction cup being disposed at one end of a bellows having folds over its complete periphery, the other end of the bellows being attached to the nipple of the suction pipe, and the wall of the bellows comprising elastic material and the spring rigidity of the elastic material in opposed halves of the wall being different.
  • a tilting device for lifting objects with flat top surfaces, in particular for sheets of paper comprising a liftable, inclinable suction cup connected with a nipple of a suction pipe, the suction cup being connected to one end of a bellows having a straight central axis connected at its other end to the nipple of the suction pipe, over its complete periphery the said bellows having both folds and approximately the same axial rigidity, and the suction cup being inclined to the straight central axis of the bellows.
  • a tilting device for lifting objects having flat top surfaces comprising a liftable, inclinable suction cup connected with a nipple of a suction pipe, the suction cup being disposed at one end of a bellows having folds over its complete periphery, the other end of the bellows being attached to the nipple of the suction pipe, and two diametrically opposite halves of said bellows respectively having a different axial spring rigidity the wall of the bellows being of an elastic. material and thicker on one half than on the other.
