(54) DEVICE FOR FORMING AND BANDING

one

The invention relates to forestry equipment, in particular, to devices for forming and wrapping timber packages.

According to the main author. St. No. 689911, a device for forming and tying log bundles is known, comprising a receiver with loading and unloading jaws and carriages with end-leveling shields equipped with a bracing mechanism in the form of a tubular semi-ring with wire for a wire, and on the carriage mounted for rotation the horizontal plane two arrows, on each of which is fixed a semiring with centering cones 1.

A disadvantage of the known device is unreliable operation due to spontaneous disconnection of tubular semirings during the wrapping.

The purpose of the invention is to increase the reliability of the device.

To achieve this goal, the device is equipped with locks, each of which contains a lever hinged on the bottom of one half-ring to interact with the strapping wire, the BELT BELTS

a gooseneck bracket, which is pivotally connected to the lever and the bracket, and a spring-loaded finger mounted on the end of the other half-ring to interact with the said lever.

FIG. 1 shows the device, a general view; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. one; in fig. 4 — node I in FIG. 3; in fig. 5 is a section BB in FIG. four.

The device consists of a base 1, at the ends of which the guides move from the drive in the longitudinal direction of the carriage 2 with their face-leveling shields 3, between which on the base 1 are mounted receivers 4 with swinging loading 5 and unloading 6 jaws. The carriages 2 are fitted with frames 7, on which drums 8 are mounted for wrapping wires with wire 9 and booms 10 mounted in pairs on axes 11 and provided with an actuator 12 for turning around them.

Claims (1)

A binding machine is mounted on one of the pairs of arrows 10, including dragging rollers 13, scissors 14, twisting gear 15 folding rollers 16, an actuator 17, and a half ring 18, which is an upper and tubular arc with a slit for exiting the binding. wire. A half ring 19 is suspended from the other of each kings of arrows 10, representing a tubular arc with a slit to exit the wrapping wire. The ends of the half-rings 18 and 19 are made with centering cones 20 and are equipped with a lock consisting of a lever 21, which overlaps the slot of the half-ring 18, brackets 22 connected by a rod 23, spring-loaded and strengthened by a hinge at the end of the half-ring 18 and the finger 24, forcibly fixed and spring-loaded half rings 19. The device operates as follows. The bundle of logs are loaded into receivers 4, while the loading jaws 5 are lowered. By moving the loading 5 and discharge 6 jaws, and aligning the ends of the bundle with the face-leveling boards 3 by moving the carriages 2 along the guide bases 16, a beam is formed. Thereafter, the carriages 2 are moved to the required distance and half-rings 18 and 19 are docked around the beam of logs. At the moment of joining the half-rings 18 and 19, the lock is activated, while the bracket 22 under the action of the CTBJ | eM centering cone of the half-ring 19 unfolds and the next moment returns to its original position, fixing the docking of the half-rings, and the spring-loaded pin 24 moves under the action of the lever 21. wire pulling rollers 13 through scissors 14, twisting the brush 15 under the folding rollers 16 on the half rings 18 and 19. The bracket 22, which is in engagement with the centering cone 20 of the half ring 19, holds the half rings 18 and 19 in The folded state is due to the effort directed towards the exploration of semirings arising during the carrying of the REVOLOKI. j: Ж -iQ 7 By turning on the raver of the pulling rollers 13, the tie wire goes out through the slit of half-rings 18 and 19 and is pulled around the bundle of logs. At the same time, at the moment of exit through the notch of the half ring 18, the bound wire raises the lever 21, unfolding the clamp 22 by means of the pull rod 23. The spring-loaded pin 24 moves and locks the lever 21, and therefore the clamp 22 in the turned position, thereby unlocking the half ring 18 and 19 After tightening, the twisting wire knot 15 is twisted and the wire is trimmed with scissors 14. By turning on the boom turning actuator 12, the binding mechanisms are moved away from the beam beyond the plane of the leveling shields. In this case, the finger 24 comes out from under the lever 21 and the system, which includes the lever 21, the bracket 22 and 23, comes to its original position. The use of the proposed device increases the reliability of operation, the quality of the formation of the package and its wrapping due to the reliable fixation of the semi-iced. The invention The device for forming and tying the bundles of logs by author. St. No. 689911, characterized in that, in order to increase the reliability of operation, it is provided with locks, each of which contains a lever fixedly hinged at the end of one half-ring for engaging with a strapping wire, a spring-loaded bracket, a rod pivotally connected to the lever and the bracket, and a spring-loaded pin mounted on the end of another half ring for engaging with said lever.
