Description

I

The invention relates to the field of wire wrapping of bags (bunches) of lengthy objects, for example logs, and can be used for mechanization of logging operations.

A device for wrapping a package of products with a wire, comprising a storage device for products, a wire feeding mechanism, a carrier with a wire clamping mechanism installed thereon, a cutting mechanism having a knife, a mechanism for twisting the ends of the wire, including movable clamps, a package support and movable twisting head 1. The disadvantage of this device is that the type of knot being formed ensures the reliability of the tie due to the double edge of the wire, which increases the tie cycle and the consumption of the tie. of material. In addition, the device is not sufficiently reliable in operation, since the twisting head must be precisely adjusted to the cross-positioning of the ends of the wire.

The aim of the invention is to increase the reliability of the device and reduce the cycle of the tie.

To do this, in the lower part of the accumulator, along its longitudinal axis, a convex plate is installed, directed by convexity inside the accumulator, and the twisting head is located in the space bounded by this plate, while the knife is fixed on the carrier.

FIG. 1 shows the device, a general view; in fig. 2 is a view A of FIG. one; in fig. 3 - - the disturbing mechanism with a clip, a detachable knife and the drive.

10 The device consists of a bypass mechanism in the form of an L-shaped drive carrier 1 with a spring-loaded clip 2 fixed on it, a knife 3 and a drive 4. The twisting head 5 (see Fig. 1) has a drive 6, and the clamping mechanism 7 has a drive 8 The twisting head 5 and the clamping mechanism are mounted on a support 9, which is capable of reciprocating through the drive 10. The device is completed with a wire cassette 11 and pressure rolls 12. The support with mechanisms installed on it is placed in space SG convex plate 13 which bulge inwardly directed accumulator for the articles and is disposed along the longitudinal axis of the accumulator for stacking the wire ends in grooves gear line twisting head and a mechanism for clamping the wire ends. The interaction of all mechanisms is carried out by limit switches 14, 15, 16. The device operates as follows. The wire from the cassette 11 is passed through the pinch rolls 12, loaded into clamp 2 (position I of carrier 1 in Fig. 2), fixed in the clamp by means of a power drive 4, and the device is prepared for automatic operation. The carrier 1 from position I performs a circular motion (in this case counterclockwise, see Fig. 2) and at the same time provides the wire around the bundle and its necessary tightening due to the braking action of the pressure rolls 12, and also lays the ends of the wire at the level the slots of the twisting head 5 and the clamping mechanism 7, thanks to the plate 13. In position II, the limit switch 14 turns off the drive and drives the actuator 10 of the slide 9. When the slide moves from position III to position IV, the wire ends are caught in the slots of the head 5 and I 7. At the end of the caliper movement, the limit switch 15 turns on the actuators 4, 6, 8 of the carrier. At the same time, the ends of the wire are clamped by the clamp 2, the wire is released from the clamp 2, the ends of the wire are twisted and the carrier moves on its trajectory to position I, where it opens the clamp 2 and captures the wire with the limit switch 16, which simultaneously turns on the actuators 4, 8. When this occurs, the clamping and cutting of the wire and the release of the node from the clamps 2. With some delay, actuators 10 and 6 are turned on, by means of which the caliper is retracted to position III and the torsion head is unwound to its original position. The present invention improves the reliability of the dressing device, automates the binding process, shortens the bundling cycle during coastal forest rafting by 1.5-2 times, frees up the worker and gives an economic effect of about 800 rubles per set. Claims A device for wire wrapping, containing a storage device for items, a carrier with a clip for wire, a movable twisting head for fastening the ends of the wire and a knife, characterized in that, in order to improve reliability, at the bottom of the accumulator .-, , - - a convex plate is installed along its longitudinal axis, the convex side of which is directed inside the storage ring, and the twisting head is located in the space bounded by this plate, while the knife is fixed on the carrier.
