Definitions

  • the present invention relates to a gripper for bottles, configured to increase the working life of the gripper by means of a reduction of the wear due to use, and a machine for packaging pourable products which comprises such a gripper.
  • a gripper which is currently used comprises a first claw and a second claw.
  • the gripper is configured so that the claws rotate with respect to each other and in a working plane, so as to open and close the gripper.
  • the gripper comprises a spring for keeping the gripper in the closed position.
  • the gripper comprises a cam follower device for opening the gripper counteracting the action of the spring, by means of contact with an external cam.
  • the spring and the device are connected to said first claw at different heights with respect to a direction transverse to the plane. In this way a twisting moment acting on the claws following said contact is operatively created. This twisting moment increases the wear of the claws and therefore reduces the available working cycles of the gripper.
  • the weight of the bottle tends to create a bending moment on the claws, which is also a source of wear.
  • a gripper according to the present description or according to any one of the attached gripper claims has a working life greater than the grippers of the prior art.
  • a machine according to the present description and/or according to any one of the attached machine claims comprises a gripper according to the present description and/or according to any one of the attached gripper claims.
  • FIG. 1 is a top plan view of the gripper
  • FIG. 1 is a bottom plan view of the gripper
  • FIG. 3 is a right-hand side view of the gripper
  • FIG. 4 is a rear view of the gripper
  • FIG. 5 is a perspective view from below of the gripper.
  • the gripper 1 is a gripper for bottles.
  • the gripper 1 comprises a first claw 2 and a second claw 3.
  • the gripper 1 is configured so that the first claw 2 and the second claw 3 rotate in a working plane P for opening and closing the gripper 1 .
  • the claws 2 and 3 rotate with respect to each other and in this plane P so as to open and close the gripper 1 .
  • the gripper 1 is in the closed position, retain the bottle by its neck.
  • the claws 2 and 3 when the gripper 1 is in the open position, may receive or release the bottle.
  • the gripper comprises a spring 4 for keeping the gripper 1 in the closed position.
  • the gripper 1 comprises a cam follower device 5.
  • the device 5 is configured to open the gripper by counteracting the action of the spring 4 and by means of contact with an external cam.
  • the spring 4 and the device 5 are connected to the first claw 2 and/or produce respective actions on the first claw 2, at different heights with respect to a vertical direction Y.
  • the vertical direction Y is operatively parallel to the force of gravity.
  • the vertical direction Y is transverse to said plane P, as may be noted in particular in Figures 1 to 4.
  • the direction Y is parallel to the respective axes of rotation of the claws
  • the working plane P is to be regarded as being parallel to or coinciding with the plane of Figures 1 and 2.
  • the vertical direction Y is perpendicular to the plane of Figures 1 and 2.
  • the vertical direction Y is parallel to the planes of Figures 3 and 4.
  • the working plane P is perpendicular to the plane of Figures 3 and 4. Therefore, operatively, a twisting moment acting on the claws 2 and 3 is created, said moment arising from the combined action of the spring 4 and the action due to contact between device 5 and cam. This twisting moment tends to cause the assembly comprising the first claw 2 and the second claw 3 to rotate in an anti-clockwise direction with respect to Figure 4.
  • the gripper 1 comprises a support system 6.
  • the gripper 1 is configured so that the support system 6 counteracts said twisting moment so as to limit or prevent the undesired rotation of the claws 2, 3, which undesired rotation is due to or could be due to said twisting moment.
  • the cam follower device 5 comprises a first cam follower roller 51 a.
  • the device 5 comprises an arm 52 which is structurally interposed between the first roller 51 a and the first claw 2.
  • the first roller 51 a makes contact with the cam and transmits to this arm 52 the action resulting from the contact between first roller 51 a and cam.
  • the spring 4 and the first roller 51 a are positioned at different heights with respect to the vertical direction Y and therefore produce on the first claw 2 actions situated at different heights with respect to the vertical direction Y.
  • the device 5 could also comprise a second roller 51 b, having the same functions as the first roller 51 a.
  • the support system 6 comprises a support plate 61 .
  • the support system 6 comprises a first abutting body 62.
  • the first abutting body 62 is mounted on the support plate 61 .
  • the first abutting body 62 is at least partially interposed between the support plate 61 and the arm 52, for abutting against said arm 52. In this way the support system 6 manages to limit or prevent, by means of few components, the aforementioned undesired rotation of the claws 2 and 3.
  • the spring 4 is connected to the first claw 2 indirectly by means of the arm 52.
  • the arm 52 and the first claw 2 are situated on mutually opposite sides with respect to a first fulcrum 7, about which said first claw 2 can rotate to open and close the gripper 1 .
  • the gripper 1 comprises the first fulcrum 7.
  • the gripper 1 also comprises a second fulcrum 9 about which the second claw 3 is able to rotate for opening and closing the gripper 1 .
  • the gripper 1 also comprises a coupling 8 for ensuring that rotation of the first claw 2 during opening of the gripper 1 also corresponds to rotation of the second claw 3 during opening of the gripper 1 and so that rotation of the first claw 2 during closing of the gripper 1 also corresponds to rotation of the second claw 3 during closing of the gripper 1 .
  • This coupling 8 is a gear tooth type coupling.
  • the arm 52 is integral with the rotation of the first claw 2. In this way the arm 52 is used effectively both to transmit to the first claw 2 the action arising from the contact between the first roller 51 a and the cam so that the undesired twisting moment is counteracted by means of the first abutting body 62.
  • the first abutting body 62 comprises a respective upper portion 621 which is interposed between the support plate 61 and the arm 52.
  • the first abutting body 62 comprises a respective lower portion 622 which is inserted in the support plate 61 .
  • the lower portion 622 is narrower than the upper portion 621 or defines a narrowing of the upper portion 621 . In this way the upper portion 621 may be formed so as to increase the counteracting and abutting action on the arm 52, while the lower portion 522 is optimized for mounting of the first abutting body 62.
  • the support system 6 is also configured to counteract a bending moment operatively acting on the claws 2 and 3 owing to the weight of the bottle.
  • the support system 6 comprises a second abutting body 63.
  • the second abutting body 63 is mounted on the support plate 61 .
  • the second abutting body 63 is at least partially interposed between the support plate 61 and the first claw 2, for abutting against the first claw 2.
  • the second abutting body 63 and the first abutting body 62 are situated on opposite sides with respect to the first fulcrum 7. In this way the second abutting body 63 may limit or prevent undesired rotation of the first claw 2 which could be due to or which is due to said bending moment.
  • the second abutting body 63 also comprises a respective upper portion 631 which is interposed between the support plate 61 and said first claw 2, and a respective lower portion 632 which is inserted in said support plate 61 .
  • the lower portion 632 of the second body 63 is narrower than the upper portion 631 of the second body 63 or defines a narrowing of the upper portion 631 of the second body 63.
  • the support system 6 comprises a third abutting body 64.
  • the third abutting body 64 is mounted on the support plate 61 .
  • the third abutting body 64 is at least partially interposed between the support plate 61 and the second claw 3, for abutting against the second claw 3.
  • the third abutting body 64 and the first abutting body 62 are situated on opposite sides with respect to the second fulcrum 9. In this way the third abutting body 64 may limit or prevent undesired rotation of the third claw 3 which could be due to or which is due to said bending moment.
  • the third abutting body 64 also comprises a respective upper portion 641 which is interposed between the support plate 61 and the second claw 3, and a respective lower portion 632 which is inserted in the support plate 61 .
