SU123447A1 - Bale wrapper for bags, bales, etc. wire - Google Patents

Description

Wire wrappers for bags, bales, bales, etc., with wire from coils, containing pivoting shoulders with pliers at the ends for gripping the wire and for circling it around the bag in one turn towards wire clippers twisting the wire with its end and cutting wire, known. A disadvantage of such automata is that they are not suitable for wrapping packages, etc., with several turns of wire.

In the described automaton, this drawback is eliminated by the fact that the wire clamp pliers are mounted on the arms of gears rotating coaxially with gears that have a groove for controlling the movable pliers lever, but with a different number of revolutions.

FIG. 1 shows an automatic front view; in fig. 2 --- same side view; in fig. 3 is the same, top view.

The machine can be used as a station in the packaging of packaging of various goods, having a conveyor or a roller table for posting packages, etc., through an automatic machine that can be activated by the package itself, ket. The conveyor or roller conveyor 1 delivers the package 2 to the place of tie-up, the package being held in the required position, presses the limit switch 3 of the conveyor, simultaneously turning on the electric friction clutch 4 on the shaft of the electric motor 5, operating continuously. When switched off, clutches 4 come into rotation with gearbox 6, gear 7 on its shaft, two parasitic gears 8 and gear 9. On shaft of gear 7 there is a fixed arm 10, which is a fixed lever of gripping pliers rotating in one direction with gear 9 On the axis 11 of the shoulder W pivotally mounted movable lever 12 ticks, the end of which is included in the circular groove 13 of the gear 9, having in one section a cam shape of a larger radius than the radius of the circular portion of the groove.

Each end of the bag has one shoulder 10 with movable I-OM 12 and drive gears for them, kinematically connected chain drives 14 with a shaft 15 located under / across the conveyor. The number of revolutions of the gears 7 (and shoulders 10 and 9 are 4: 3, i.e. at four revolutions of the shoulders 10, the gears 5 will make three turns. The cam sections of the grooves 13 of the gears 9 are designed to open the tongs, i.e. to divert the end movable lever 12 from the end of the shoulder 10 at the capture and release of wires unwound from the coils 16 and passing through the pair of guide rollers 17. After clamping the end of the wire with the lever 12, the shoulder 10 tons is not behind the wire from the coil 16. On the gear 9 there are side teeth 18, reporting periodically rotation of the asterisk 19 with the cam (inter acting with the limit switch 20} of the electromagnetic brakes 21 of the coils 16. Braking of the coils 16 causes tension on the wires before the end of wrapping of the bag. When releasing the brakes 21 of the coils 16, the electric friction couplings 4 and 22 turn on and the electric motor 23 drives the pliers 24, twisting the wire and cutting the wire, working continuously and through the sleeve 22, bevel gears 25 and 26 transmits rotation to the penster 27 coupled to the rack 28 to move the slide 29 towards the stack 2 along the inclined guides 30 we are automatic.

When the caliper 29 reaches the extreme position, the limit switch 31 will operate and the electric drive clutches 32 of the gears 33 and 34 will turn on. The gears 34 have grooves for controlling the tongs 35 with knives on the sides (nippers). When the tongs 35 clamp the wires from the coils and their ends in the tongs of the shoulders 10, the limit switch 36 will operate and the electric friction clutches 32 and 37 will turn on, as a result of which the tongs 35 will come into rotation, twisting the wire and pulling the packet.

Worm 38 drives the pincer 39 to rotate the gear 39, on the axis of which sits the cam 40, which, making one turn, pushes the limit switch 41, as a result of which the electric friction clutch 37 is turned off and the electric friction clutch 42 of the gear 26 returns to its original position position. When the caliper reaches this position, the switch 43 will operate, turning off the electric friction clutch 42.

This concludes the wire looping cycle.
