(54) MACHINE FOR ROLLING AND ROLLING OF STRIP MATERIALS with new cassettes; FIG. 4 is a section along A-A in FIG. 3; in fig. 5 - device for lifting and lowering the cassettes; in fig. 6 same plan view; in fig. 7 - device for fixing the cassettes; in fig. 8 — a device for centering the cassettes; in fig. 9 mechanism for seaming and rolling. .. ,, The machine for rolling and rolling of strip materials contains a frame 1 with a mechanism 2 movably mounted on it for moving the cassettes (see Fig. H), which moves along the guides 3 from the electric motor 4 by means of a V-belt drive 5, screw 6, the carriage 7 and the tractor 8 connected to the mechanism 2. The mechanism 2 for moving the cassettes has a two-letter movable platform 9 with rollers 1O (see Fig. 4), moving the imis along the guides 4 mounted on the frame 1. The mobile platform 9 has two devices 11 for raising and lowering cassettes, one and Which accepts an empty cassette at the installation position 12 and participates in moving it to the rolling position 13, and the second accepts an empty cassette at the rolling position 13 and moves it to the removal position 14, Each device 11 (see FIGS. 5 and 6) for lifting and lowering the cassette has two pairs of prismatic rollers 15 movably mounted on the hinged levers 16 rigidly fixed on the shafts 17. At the other ends of the levers 16, the stem and eye of the pneumatic cylinder 18 are hingedly attached, and the sprockets 19 are rigidly mounted on the shafts 17, connected by a cross 2 O chain. At the crossing point of the 2 O chain, there is a frame 21, passing a 2O chain in its groove, the ends of which are fixed on both sides of the frame 21. To hold the prismatic rollers 15 in the upper position, the levers 16 are fastened to the pneumatic cylinder 18 by the spring 22. To lower the prismatic rollers 15, a pneumatic cylinder 18 acts on one ends of the hinged levers 16 rigidly connected to the shaft Nffl 17, Chain 2O and sprockets 19 are designed to synchronize the rotation of each pair of levers 16. The cassette 23 has two cheeks connected: -cylindrical tie rods by which it is mounted on prismatic role ki jaws 15. Between the cassette 23 is movably mounted on the top roll for laying and bottom seaming roll for strip docked or tissue. On the outer sides of the cheeks, the cassette 23 has two cylindrical pins with which: it is placed on the prisms of the fixing device 24 and 25 of the cassettes located on the frame, respectively, at the positions of the crimping 13 and the removal 14, Fixing devices 24 and 25 (see FIG. , 7) the cassettes have a pneumatic cylinder 26, the rod of which is pivotally connected to the strap 27, rigidly fastened with shanks 28, which mix in the guides 29. pneumocycle position indrami 26. To center the cassettes 23 on the positions of installation 12 and removal 14, two identical devices for centering 31 and 32 (see Fig. 2) of cassettes are mounted. They contain movable strips 33 (see Fig. 8), on which freely rotating rollers 34 are mounted. Movable strips 33 are actuated by lever system 35 from pneumatic cylinder 36 located in the upper part of frame 1. Centering cassettes 23 at the position of the roll-in 13 is carried out The straps 37 rigidly mounted on frame 1, having freely rotating rollers 38. The mechanism for rolling and rolling 39 (see FIG. 1) is fixed with brackets 4O and 41 (see FIG. 9) on frame 1, the rubberized roller 42 extends pneumatically 1 forward 43 and pressed at sunset e to the bottom, while the upper spool raskatgse cassette 23 pnevmotsilind-. rum 44, roller 42 is driven by a chain transmission 45 and 46 from an electric motor with a gearbox 47. The machine works as follows. In the initial position, the movable platform 9 is in the leftmost position (see FIG. 3), i.e. installation position 12 cassettes. The prismatic rollers 15 of the movable platform 9 (see FIG. 5) are omitted both at the installation position 12 and at the seaming position 13. The movable strips 33 (see FIG. 8) at the installation position 12 and removal 14 are divorced to the extreme / Scary Prism AOR (see Fig, 7.) relegated to the extreme right position (shown by the dotted line). The roller 42 (cm, fig, 9) is retracted to the extreme right position.

The cassette 23 is mounted with the help of a hoist or other lifting mechanism on the installation position 12 with its cylindrical straps on the prismatic rollers 15 of the movable platform 9. The device for raising and lowering 11 cassettes moves the cassette to the upper position, and the centering devices 31 and 32 of the cassettes, converts the movable slats 33 and with their rollers 34 center the cassette 23 relative to the center line of the machine. Then, the movable platform 9 with the cassette 23 installed is moved to the removal position 14, as a result of which the installed cassette 23 is located at the rolling position 13.

The pneumodilles 26 extend the prisms 30 forward simultaneously to the positions of the pins 13 and removal 14. The prismatic rollers 15 by the pneumatic cylinders 18 are lowered and the cassette 23 with its cylindrical pins located on both sides of the cheeks is fixed on the DZ prisms and held by them. Next, the movable platform 9 is moved by the electric motor 4 to the initial position - to the installation position 12, where the empty cassette 23 is mounted on the prismatic rollers 15,

At the same time, the end of the rolled fabric is filled onto the lower bobbin of the cassette 23, the roller 42 is pushed forward by the pneumatic cylinder 43, and the pneumatic cylinder 44 pushes the roller to the lower reel of the cassette 23. The motor with gear 47 is turned on and through chain gears 45 and 46 the rotation of the roller 42 is transmitted rolling material into the gasket. The material being rolled comes either from a conveyor or from a compensator installed in front of the machine for rolling.

At the end of seaming, the cutout 1nenny roller 42 is retracted to the initial position by pneumatic cylinders 43 and 44, the electric motor with gear 47 stops, the prismatic rollers 15 of the movable platform 9 are shifted to the upper position on POSITIVE seaming and installation, the cassette 23, located at the seizure position, prismatic rollers 15 is removed from the prisms 30 and lifted, the cassette also being moved to the installation position is also moved to the upper hollow by the prismatic rollers 15. The rolled-up material is cut,

The priams 30 at the positions of the seaming 13 and of the removal 14 are simultaneously removed to the initial position by the pneumatic cylinders 26, the movable platform 9 moves the cas6

sets from positions of installation 12 and roll-ups J 8, respectively, at positions of roll-out 13 and removal 14. At the end of the movement of the platform 9, the prism of the DA extends forward, the prism rollers 15 are lowered and the Kai sets 23 with their cylindrical trunnions are fixed on the prism of the radar and hold-down: 1 × -. with them.

The movable platform 9 moves to its original position. The cassette 23 / cassette 23, located at pickup position 14 by a hoist or other lifting mechanism, is removed from prisms 30 and transmitted to the transport system, with the movable slats 83 of the centering devices discharging the cartridges 30 at the same time. Then, at the installation position 12, the empty cassette 23 is mounted on the prismatic rollers 15 of the mobile plate 1} of the turret 9, while the movable strips 33 of the centering devices 31 and 32 converge and center the installed cassette relative to the axial line of the machine. Then the cycle repeats.

The machine can work both in the automatic machine of the 1st cycle of operations and with manual control,
