Description

The invention relates to packaging and can be used to wrap products with wire.

The aim of the invention is to provide a supply of a predetermined length of wire necessary for tying products when resizing them.

Making two detachable I-shaped wiring elements and setting parallel branches of elements one against the other facilitates the insertion of the tied product into the wiring and regulation of the length of the wire, covering the wired section of the products.

The sequential arrangement of parts of the channel on the wiring elements and the presence of ramps facilitates the exit of the wire from the channel during tension, and the execution of the input and output sections in one of the wiring elements simplifies the process of twisting the ends of the wire.

Fig. 1 schematically shows a guide device for pulling the strap wire together with a binding head; FIG. 2 is the same, rotated in FIG. 3 is a guide device with a binding head, the first part; figure 4 - the same, the second part; Fig. 5 is a side view of the device in the open state with associated products, side view; Fig. 6 shows the same in the closed state immediately before the start of binding.

A coil of wire 1 (indicated by a dash-dotted line) of a cylindrical ring shape that needs to be tied up in several planes is placed in a binding machine, shown on the drawing only by a coupling head 2, through which the direction The connecting wire, which should cover the cross section of the bundle 1. For this purpose, wire 3 surround this cross section of the skein in order to guide the wire in the direction of channel 4 and then return it to the coupling head 2, as indicated by the arrow Fj. Wiring 3 is similar to a plate: it consists of the first 5 and second 6 detachable elements, located on both sides of the plane of their connection, parallel to the main opposite outer surface of the plate.

These connections, when elements 5 and 6 are connected, are in contact with each other with their internal surfaces 7 and 8, in which channel 4 is made. Figure 2 shows that when the connecting wire encompasses the product to be bound, the device is opened by relative extension elements 5 and 6 allows the wire to be released so that the bonding head 2 is bound to it.

Figures 1 and 2 show a coupling head 2, independent and located outside the wiring 3. It is preferable to embed the communication head 2 into wiring 3, as shown in Fig. 3, so that the internal channels of the head 2 become part of the guide channel 4, thereby reducing the length of the binding wire in the device before twisting it.

The tie head 2 embedded in wiring 3 is independent because it must rotate around its axis in order to twist the two free ends of the binding wire together. Before performing the twisting operation, the binding wire forms a loop, the two ends of which intersect, preferably spaced apart from each other by a distance equal to the diameter of the wire.

FIG. 5 and 6, the binding head is not shown.

In order for the skein 1 or any other connected products to be placed inside the wiring, each of the elements 5,6 is U-shaped with two branches 9 and 10 spaced apart from each other for the first element 5 and 11 , 12 for the second element 6. These branches are turned to each other from their junction zones 13 and 14.

When elements 5,6 are spaced apart from each other in the direction of their respective branches (Fig. 3), a linked skein 1 can be placed between them. When the elements 5,6 are shifted and their inner surfaces 7,8 are in contact, branches 9-11 and 10-12, together with the zones of their connection 13, 14, limit the central opening 15 (Fig. -6).

The central hole 15 has two concave opposite sides 16,17, with side 16 located on element 5, and side 17 - on

.

element 6 in the joint zones 13 and 14, the central hole 15 also has two opposite straight sides 18, 19, each of which is formed by one branch of the first element and one branch of the second element (branches 9 and 11 for side 18 and branches 10 and 12 for side 19)

As a result of the longitudinal internal surfaces 7.8 relative to each other, the proposed device allows to obtain a central opening 15 of variable size. From the first extreme relative position of the two elements 5,6, in which the concave sides 16, 17 of the opening are closed, limiting a practically round hole, this hole of the minimum size can be absolutely round if each of the sides 16 ,, 17 is made in the shape of a semicircle. In the second extreme relative position, when the inner surfaces 7, 8 are in contact only with their ends, a very elongated central opening 15 is obtained, the two concave sides of which 16.17 are interconnected by two straight sides 18, 19 of maximum length. Intermediate hole sizes are also possible.

In the proposed device, the guide channel 4 is alternately made in the first and then in the second inner surface 7, 8 of the two elements 5,6,

In each of the joint zones 13, 14, the guide channel is made in that of two elements 5, 6, which form the VT 16, 17 side of the central opening 15. In the first element 5, the first part is made — a quarter of the channel 20 in a quarter of a circle (FIG. and 5), open inside the central hole 15 with the concave side 16. Reaching the branch 9, the first part 20 moves away from the rectilinear side 18. This part preferably takes the form of a quarter of a circle tangential to the concave side 16, which has a larger radius of curvature. It is interrupted as it enters branch 9 in the direction of the arrow of movement of the bonding wire pushed along channel 4. It ends in branch 9 with ramp 21, which rises to the level of the inner surface 7. Ramp 21 provides connection to the second

4 h - Q you are in Q a - a straight line part 22, made in the inner surface 8 of branch 11, which can slide along the surface 7 of branch 9. When the second part 22 reaches the junction zone 14, it continues with the third part 23 in the shape of a semicircle, tangent to the concave side 17 of the central hole 15, Part 23 is open inside the central hole 15, Reaching branch 12, the third part 23 of the channel leaves from the rectilinear side 19 and ends with ramp 24, which rises to the level of the inner surface 8, Ramp 24 provides connection with even When it reaches the junction zone 13, the fourth part 25 of the channel 4 continues with the fifth part 26, which has the form of a quarter of circumference tangent to the side 16 of the central hole 15, P that part 26 is open inside the central hole 15, I

The first portion 20 of the channel communicates with the rectilinear inlet portion 27 of the channel 4 in the direction F of the bonding wire; The fifth portion 26 terminates in a rectilinear output portion 28 of the channel 4 in the direction F of the exit of the bonding wire. The straight sections 27, 28 communicate with the channels of the bonding head 2 or, more preferably, are part of the head. one

Whatever the length of the central hole 15, which is adjusted by moving the inner surfaces 7, 8 of the two elements 5, 6 relative to each other, the connecting wire is directed in the direction from F, and Fj in all successive parts 20-25 of the guide channel 4, the concave sides 16,17 of the central opening 15 may come into contact with the associated products, as shown in FIG. 6. In other words, the bonding wire comes into contact with the bonded products only in connection zones 13, 14, regardless of the size of the central hole 15. As a result, the bonding wire has practically no excessive length relative to the perimeter of the bonded products. The bent portions 20, 23, 26 of the channel have a larger raz513

bending radius than arc-shaped wiring crown 3,

In Fig. 4, in the connection zone 14 between the branches 9, 10 of the first element 5, the second element 6 has a thickening 29, which limits the part 23 of the channel 4, and the straight parts 22, 25 is bounded by the corresponding opposite the inner surface of the branches of the opposite element.

Along the concave side 16 on the first element 5, the two parts 20 and 26 in the shape of a quarter of a circle are not in the same plane; they are perpendicular to the plane of FIG. 5 so that the areas of the inlet 27 and the outlet 28 are separated from each other by a distance equal to the diameter of the bonding wire.

Thus, with the help of this device, the wire is provided with the necessary configuration around the products to be bound and of a given length in order to eliminate the need to sample the excess length of the wire,
