Definitions
- the invention relates to a retractable and extendable Support pin for clamping wound on sleeves Paper webs according to the preamble of the claim 1.
- US 29 22 592 A discloses a retractable and extendable Support pin for holding a supply roll. Are there Terminal strips movable in the radial direction are provided, which have a material compression rib.
- the invention has for its object a driven trunnion with in the radial direction to create movable terminal strips, which the total driving and braking forces on the sleeve as the Core of the winding or unwinding roll transfers, the Sleeve despite high momentum, especially when the machine stops quickly, almost remains undamaged.
- a trunnion 1 has several over its circumference evenly spaced, z. B. four extending in the axial direction of the trunnion 1 Terminal strips 2, 3, 4, 5, which by means of a 4 drive shown against a sleeve 7th Act.
- the sleeve 7 can be wound from a spiral Kraft paper strips exist and a wall thickness d, to have approx. 25 mm for the purpose of receiving onto the sleeve 7 wound paper webs.
- the terminal strips 2 to 5 are in the radial direction to the axis of rotation 8 of the Trunnion 1 movable so that it is in the working position emerging from the periphery 9 of the trunnion 1 against the inner wall 11 of the sleeve 7 act.
- Each of the four Terminal strips 2 to 5 is on their sleeve 7 facing side with a longitudinal axis 10 of the terminal block 2 to 5, so parallel to Rotational axis extending, symmetrical arranged material compression rib 12, 13, 14, 15 Mistake.
- This material compression rib 12 to 15 each has a rounded, facing the sleeve 7 Head surface 17, 18, 19, 20, which by an amount t symmetrically over two of the sleeve 7 also facing Shoulder surfaces or shoulders 23, 24; 26, 27, 28, 29; 31, 32 of the terminal block 2 to 5 protrudes.
- Each Material compression rib 12 to 15 has next to her Head surface 17 to 20 on two side surfaces 21, 22 with a height t that extends in the direction of the longitudinal axis 10 extend (only in Fig.
- Each material compression rib 12 to 15 has in addition their head surface 17 to 20 with two side surfaces each at a height t, which is in the direction of Extend longitudinal axis 10 (only shown in Fig. 3 for the Material compression rib 12).
- a diameter D of the trunnion 1 can between 3, 5 to 4 times a width B of Terminal strips 2 to 5 are located.
- the distance e can e.g. B. be five millimeters (Fig. 5).
- a length l of the terminal block is 2 to 5 greater than a length l - a - e of both Material compression ribs 43, 44 together (Fig. 5).
- the material compression rib 12 to 15 each off-center on a shoulder surface 23, 24; 26, 27; 28, 29; 31, 32 of the terminal block 2 to 5 is arranged, d. H. outside the longitudinal axis 10 of the terminal block 2 to 5 runs.
- the piston rod 33 is with surrounded a spring washer 39, which is between the piston crown of the cylinder-piston unit and one Housing wall 41 supports. Should one in FIG. 4 not shown sleeve 7 with or without it wound paper web are changed, so the Cylinder-piston unit pressurized with compressed air, see above that the piston with the piston rod 33 against the force the plate spring assembly 39 axially in the direction of the trunnion 1 is moved and thus the terminal strips 2 to 5 with the Material compression ribs 12 to 15 in radial Direction of the trunnion 1 are retracted so far, that the top surfaces 17 to 20 of the Material compression ribs 12 to 15 within the Periphery 9 of the trunnion 1 lie (rest position).
- the terminal strips 2 to 5 are each by means of reset the force of leaf springs 42.
- the penetration depth T is at least 15% of the inside Diameter D of the sleeve 7 and the diameter D of the Tragzapfens 1.
