Description

(54) DEVICE FOR BINDING WIRE PACKAGES OF FIGURED PRODUCTS

one

The invention relates to the mechanization of the packaging of shaped articles, such as shovels.

According to the main author. St. No. 512121 discloses a device for wrapping packages of shaped articles, e.g., shovels, comprising a housing, the top plate of which has slots, a disk made with spiral grooves and mounted on a shaft rotatably, and stops located under the disk 1.

However, this device does not provide the necessary tightening of the package, since due to the combination of the weft and the process of forming the twisting assembly, the wire in the twisting assembly often breaks. The device also displaces the twisting knot relative to the disk center, since the ends of the wires have different tension, which entails the different part of the ends of the wires in the process of forming the twisting knot. The disadvantage is the destruction of the wire, due to a sharp increase in the force of friction of the wires against the edge of the groove of the disk.

The purpose of the invention is to increase the reliability of the device, to provide the necessary wire tightening and to prevent the twisting assembly from moving relative to the center of the disk.

This goal is achieved by the fact that the stops are formed by a horizontal plate 5 with slots and clamps for wire containing a rusk and a rotatable spring-loaded lever, with a ball for a twisting knot in the center of the disk.

FIG. 1 shows the device, a general view; in fig. 2.- view along arrow A in FIG. one;

10 in FIG. 3 is a view along arrow B in FIG. one; in fig. 4 - position of the wire at the time of package wrapping; in fig. 5 and 6, the location of the clips on the plate.

The device includes a housing 1, the upper plate 2 of which has slots 3 and a disk 4

 with spiral grooves 5. The disk 4 is mounted on the shaft 6 rotatably from the drive 7. Under the disk 4 there are lugs made in the form of a plate 8 with slots 9. On the plate 8 there are clips 20 we each consisting of crackers 10 and a lever 11, installed with the possibility of rotation about the axis 12 by means of a spring 13. Plate 8 is installed

under the disk 4 on the support 14. The clips serve to grip the ends of the tie wires 15.

The disk 4 is also provided with a shaping ball 16 mounted at the center of the disk 4 in the frame 17. The ball 16 is designed to protect the displacement relative to the center of the disk 4 of the twisting assembly and prevent the destruction of the wire 15 in the twisting assembly.

In addition, the brackets 18 are reinforced on the housing 1, between which two semi-axle levers 20 are fastened on the shaft 19. At one end of the semi-axle 20 levers, the rocking arm 21 is strengthened, hingedly interconnected with the shaft 22 of the power cylinder 23, which is hinged on the arm 24 mounted on the housing 1.

Each arm of the half-cassette .20 has at the end a rigidly reinforced cheek 25, at a given distance from which the second cheek 26 is hinged, hinged 27.

The structure works as follows.

The shovels with their cups are placed between the cheeks 25 and 26. Then the ends of the U-shaped wires 15 are turned around the products into the holes formed by the slots 3 of the upper plate 2 of the housing 1, the slots 5 of the disc 4, the slots 9 of the plate 8.

After this, the drive 7 is turned on, the disk 4 that rotates the rotation. When the disk 4 rotates clockwise, due to the spiral grooves 5 and the slot m 3, the ends of the U-shaped wires 15 move to the center of the disk 4, bending under the spades pack. The ends of the wires 15, resting in the edge of the plate 8, pass between the breadcrumbs 10 and the lever 11 located on the plate 8. Thanks to the adjusting force of the springs 13, the need to tighten the shovels is achieved.

Due to the simultaneous approach of the ends of the wires 15 to the center of the disk 4, the process of twisting begins, to the beginning of which the ends of the wires 15 come out of the clamps, resulting in the beginning of the formation of the twisting assembly without destroying the wires 15. A further formation of the twisting assembly occurs on the surface of the forming ball 16. Due to this, there is no displacement of the twisting knot.

From the center of the disk 4, as well as the tension forces of the wire (the forces leading to the destruction of the wires in a twist) do not change drastically due to the constant angle formed by the ends of the wires 15 and the surface of the disk. In the absence of a ball-forming base, the base of the twist knot is formed at the surface of the lower spade, and during the formation of the twist knot approaches the surface of the disk 4. The movement of the base of the twisting knot results in a change in the angle between the ends of the wires and the surface of the disk 4, as a result of which the edge of the groove 5 of the disk 4, which in turn leads to the destruction of the wires 15 in the twisting node. After the formation of the twisting knot, i.e. skidding the shovels, the actuator 7 stops and simultaneously the power cylinder 23 — a dropping mechanism — the shunt 22 of which acts on the lever 21, withdraws the half-armature levers 20 from the working area and when they further move along the counterclockwise arc, the hinged hinged cheek 26 deviates, as a result, the bundled packet of shovels slides over it into the container. Further, the power cylinder 23, with its reverse stroke, returns the half-cassette levers 20 to the initial position, while the stops 27, touching the surface of the plate 2, return the folding cheek 26 to the initial position. With this device, the wrapping strength of a package of shaped articles is enhanced.
