Apparatus for picking up and guiding loops
The invention concerns an apparatus for picking up and guiding loops or the like which can be applied to articles, in particular sausage-shaped packs, comprising a loop feed means, an angled pick-up means having a front end, a pin which has a contact surface and which is movable between a first position in which it passes through the fed loop and in which the contact surface is in contact with the front end of the pick-up means, and a second position away from the front end of the pick-up means, and a drive for actuation of the contact pin. A torque support means is provided in the front region of the front end of the pick-up means and the contact surface of the pin has means for centering the pick-up means in such a way that the pick-up means does not bear against the torque support means when the pin is in the first position.
1. A pickup apparatus for use with sausage packaging machines having a loop feed means for transporting loops, the pickup apparatus comprising:
a non-rotating pickup having a first portion extending in a transport direction, said first portion connected to a pickup end, said pickup end directed at an angle with respect to the transport direction;
a moveable pin movable vertically between a first position adapted to extend through a transported loop and adapted to engage the pickup end and a second position distal the pickup end;
a torque support defining a cavity in which the pickup end is positioned, the torque support adapted to selectably engage the pickup end; and
the moveable pin having a contact surface adapted to engage the pickup end in such a way that the pickup end does not bear against the torque support when the moveable pin is in the first position, and wherein the torque support being a horizontally extending fork which selectively embraces the pickup end, the fork having a spread whose shape and width are so selected that the pickup end does not bear against the fork when the moveable pin is in the first position.
2. The pickup apparatus of claim 1 , further comprising a rotating shaft engaging the first portion of the non-rotating pickup.
3. A pickup apparatus for use with sausage packaging machines having a loop feed means for transporting loops, the pickup apparatus comprising:
a non-rotating pickup having a first portion extending in a transport direction, said first portion connected to a pickup end, said pickup end directed at an angle with respect to the transport direction;
a moveable pin movable vertically between a first position adapted to extend through a transported loop and adapted to engage the pickup end and a second position distal the pickup end;
a torque support defining a cavity in which the pickup end is positioned, the torque support adapted to selectably engage the pickup end; and
the moveable pin having a contact surface adapted to engage the pickup end in such a way that the pickup end does not bear against the torque support when the moveable pin is in the first position,
where the torque support extends horizontally partially around the pickup end.
4. The pickup apparatus of claim 3 , further comprising a rotating shaft engaging the first Portion of the non-rotating pickup.
5. A pickup apparatus for use with sausage packaging machines having a loop feed means for transporting loops, the pickup apparatus comprising:
a non-rotating pickup having a front end extending downward therefrom;
a moveable pin movable vertically between a first position extending through a transported loop and engaging the pickup front end and a second position distal the pickup front end; and
a torque support positioned about the pickup front end, the torque support selectively engaging the pickup front end, the torque support being a horizontally extending fork which selectively embraces the pickup front end, the fork having a spread whose shape and width are so selected that the pickup front end does not bear against the fork when the moveable pin is in the first position,
the moveable pin having a contact surface engaging the pickup front end is such a way that the pickup front end does not bear against the torque support when the moveable pin is in the first position.
6. The pickup apparatus of claim 5 , further comprising a rotating shaft engaging a back end of the non-rotating pickup.
7. The pickup apparatus of claim 5 where the torque support extends horizontally partially around the pickup front end.
8. A pickup apparatus for use with sausage packaging machines having a loop feed means for transporting loops, the pickup apparatus comprising:
a non-rotating pickup having a front end extending downward therefrom;
a moveable pin movable vertically between a first position extending through a transported loop and engaging the pickup front end and a second position distal the pickup front end; and
a torque support positioned about the pickup front end, the torque support selectively engaging the pickup front end, the torque support extending horizontally partially around the pickup front end,
the moveable pin having a contact surface engaging the pickup front end is such a way that the pickup front end does not bear against the torque support when the moveable pin is in the first position.
9. The pickup apparatus of claim 8 , the torque support being a horizontally extending fork which selectively embraces the pickup front end, the fork having a spread whose shape and width are so selected that the pickup front end does not bear against the fork when the moveable pin is in the first position.
10. The pickup apparatus of claim 8 , further comprising a rotating shaft engaging a back end of the non-rotating pickup.
