Description

one

The invention relates to the technique of trimming micropackages from logs with elastic cushioning elements and can be used in onshore forest warehouses where micropackages are deployed.

A device for wrapping products with elastic cushioning elements is known, comprising a lever, one end of which is designed as a hook for the elements. one

However, when tensioning these 1M devices with shock-absorbing elastic elements, great effort is required.

In order to reduce labor input when a binding element is applied, the proposed sleep / bzheno device is installed with reciprocating movement along the lever with a sleeve for elements having the shape of a truncated cone, the radius of the lower base of which is equal to the hook width, with a support comb attached to its outer side.

On the fit. 1 schematically shows the proposed device for tying products with elastic shock-absorbing elements, general view; in fig. 2 - the same, at the moment of the stop of the movable conical sleeve in the end of the hook; in fig. 3 - arrangement of the binding and the device on the micropackage in the initial position (before the start of tension); in fig. 4 - intermediate position of the device on the micropackage

in the process of stretching the elastic binding; in fig. 5 shows the position of the device and both loops of the tie after tension; in fig. 6 - knot of fixing the loops of elastic binding.

The device consists of a rod-lever 1 with a movable conical sleeve 2 worn and freely sliding along it. One end of the rod 1 is made in the form of a hook 3, the outer surface of which has a support comb 4 and the other end serves as a handle.

The conical sleeve 2 has such final diameters at which the side surface is a continuation of the outer side surface of the end of the hook (Fig. 2).

The procedure for wrapping a micropackage with elastic straps using the proposed device is as follows.

In the initial position (Fig. 3), the closed elastic lining 5, folded in half, is carried around the top of the logs of the 6 logs laid in the storage form of any design. One loop of the tie, double-sided, is placed in the flat shed of the hook 3 of the device, and the other is placed on the conical sleeve 2.

By lifting the device along the rod towards the handle, the support comb 4 abut it into one of the upper logs of the bundle being tied together. The rotation of the rod-lever 1 by 180 ° around the point of emphasis of the device in the log (Fig. 4) stretches the elastic strap.
