Description

The invention relates to metal rolling production, in particular to the packaging of section (round and shaped) rolled products and pipes, and can also be used for the packaging of long products in mechanical engineering.

A device for wrapping packages is known, which contains wiring for the binding wire (two in each section), through which two parallel wires are cut, spanning from both sides of the bound section, and two pairs of grippers for the ends of the wire pieces. In order to bind, the grippers are brought together in pairs, and the wire segments thus bend around the bound section on both sides with tension.

At the end of the process of convergence, the ends of the wires are twisted together with rotation of the grippers provided with an appropriate drive for their rotation. Formed by casing has two twisting knots.

Each of the conductors is provided with a collet chuck and at the same time plays the role of a binding wire feeder during the forward movement of the collet clips to the long grip of the device for twisting the ends of the wires. After securing the end of the wire in the long grip, the collet clamp of the wiring returns to its original position, the wire is secured by the grip of the near stranding device, and its measuring length is cut off with a knife.

ABOUT

The device is intended for wrapping the entire cross section of the package and the binding performed by it cannot prevent the package from losing its shape if the package structure formed by packaged rolling is unstable by itself, as is the case for round steel and pipes.

The design of wire harness and devices for twisting the wire ends is difficult and cannot be used to carry out another system for wrapping a package other than the entire section,

The quality of the binding and its reliability cannot be high, since the ends of the wires are twisted towards the package being bound, which Ke eliminates the presence of residual clearance under the knot or the wire break at the end of the twist.

The purpose of the invention is to expand the technical capabilities of the device with respect to the assortment of rolled products packaged in tetrahedral packages, simplify the design of the device and improve the quality of the binding of the package. .

This goal is achieved by the fact that in a known device comprising a casing, mechanisms for supplying rolled products, forming a package, feeding and wrapping the binding wire, cutting wires for the binding wire, and a device for twisting the ends of the binding wire provided with a drive for rotating them, each the wire for the strapping wire is made in the form of an open groove in the rail and the bottom of the groove is reinforced with permanent magnets, and the device for twisting the ends of the strapping wire is a sleeve with a movable spring-loaded cup, in the bottom part of which there are holes for the passage of the binding wire, while the sleeve is installed in the drive housing of its rotation and this housing is rotatably mounted on the device housing, and the rail with the wire groove for the wire in the space between each pair of fixtures twisting the ends of the wires is fixed on the mechanism for feeding the formed bundle of rolled metal to the position of its binding.

Figure 1 is a schematic diagram of the device (side view); Fig. 2 is a view A of the wire harness; Fig. 3 shows a device for twisting the ends of the wires; Fig. 4 shows a variation of the drive for rotating the device for twisting the ends of the wires (plan view).

The rental package 1 shown in FIG. 1 consists of a series of consecutively tied sections (packs of rolled products), which are collected in a pocket limited to one

side of the bundled part of the package 1, and on the other side of the side wall of the rolling table 2. A constructive solution involving the use for rolling packs from goal 2 and

0 pusher 3 is conditional. In this solution, pusher 3 serves both to push the rolled stock from the table 2 into the pocket, and to move the bundle formed in the pocket to the binding position.

5The interconnecting part of the device contains the rotations installed on the brackets A of the ROD gantry 5 and from the base 6 of the casing of the devices 7 for twisting the:

0 drives rotational actuators (bushings). The rotation mechanisms of the housings 7 include a shaft 8, an actuated wheel 9 and a gear sector fastened to the housing. The feeding mechanism of the binding wire 11 includes a guide rail cc / yunk i2 for a movable collet gripper S3 driven by, for example, a screw drive 14.

Circuit wire enters the wire feed mechanism after proak. and dimensional segments. The correct feeding mechanism and knives for simplification on e-ir. not shown.

For centering the front end

5 wires along the axis of the holes of the coping element of the fixture for carrying out the rounding of the ends of the binding wire on the column 12 of the load. funnel 15. and on the pusher 3 (on his inlet

0 plate) - wiring 16 in the form of a rail with a groove on the side of the rolled steel, the bottom of which is reinforced with constant m and cn and mA 17 (see Fig. 2).

Same wiring is set to L; and before

5 collet gripper 13 (not shown in figure 1).

The wrapped bag enters the grid 18.

Device for implementation

0 twisting of the ends of the stranded wires (see Fig. 3) includes a sleeve 20 installed in the housing 7 on bearings 19, which is an output element of the rotational drive, in which a cup 21 is mounted on the pin joint, pressed to the extreme position by a spring 22 and a nut 23. The bottom of the glass 21 is formed by a SUM and a rigidly fixed disk 24 of wear-resistant material with openings for the passage of the wrapping wire.

The drive to the sleeve 20 is carried out through a gear 25 of a mechanical transmission of the drive of the rotation of the sleeve which is fixedly mounted on it. The input element of the mechanical transmission of the rotational drive is, for example, a hydraulic cylinder rod 26, with which in the housing 7 a gear rack is coupled (not shown). The gear ratio of the mechanical transmission of the drive is chosen so that the sleeve 20 is rotated to the required angle in one stroke of the rod 26.. A variant of the drive for rotating the device (view in plan) is shown in FIG. 4, where 27 is the actuator hydraulic cylinder.

The device works as follows.

The set of rental packs is made by lowering the row of rods with table 2 to the required level and pushing them by the pusher 3 from the table onto the grid 18 or the previously formed row of rolled products. In this case, the pocket for the bundle (its side walls) is formed on one side of the side surface of table 2, and on the other, the wrapped portion of package 1, as shown in Fig. 1. By the same pusher 3, the formed rolling stack is pushed further onto the binding position, on which the front plane of the slab of the pusher 3 is set directly beyond the plane of the binding wire. In this case, the bodies of the twisting devices 7 are in a position rotated relative to the axis of the working channel of the device by an angle equal to (10.,. bottom gran m

After moving the formed bundle to the position of tying the casing of the device 7 for twisting the wires, the turning mechanism (pos. 8.9 and 10 of FIG. 1) is placed in a horizontal position, pressing the branch of the piece of wire to the upper and lower edges of the bundle. Turning on the drive screw mechanism 14, the collet gripper 13 moves the piece of wire 11 into the device for twisting the wires. At the same time, the front end of the wire 11 successively passes through the guide funnel 15, a wire-free hole in the disk 24, a wire groove 16 between the lower and upper wire twisting devices and a free hole, - the disk 24 of the upper wire twisting device. The piece of wire 11 is installed symmetrically with respect to the bundled bundle package 1.

Getting the front end of the wire into the free hole in the lower discs 24

and the upper devices for twisting the wires is achieved by the fact that the angle of rotation of these discs with glasses 21 when performing twisting is chosen equal to 5P rad. when the number of holes in the disk 24, equal to 2, and

20 P

glad. - with the number of these holes, ravO

Mr. 3, and also the fact that the groove of the wiring 16 is reinforced with permanent magnets, which

0 provides pushing the wire segment strictly along the axis of the free holes of the lower and upper devices for twisting the wires.

The rotational drives of the device for twisting the wires are turned on (hydraulic cylinder 27, Fig. 4). Moving the rod 26 of the hydraulic cylinder and the toothed rack installed in the housing 7 through mechanical transmission drives the sleeve 20 and the stage 21 with the disk 24 to rotate. the ends of the wires passing through the holes in each of the discs 24.

5 The pusher 3 is retracted to the initial position to form the next pack of rolled (left, extreme) position, and the housings 7 of the devices for twisting the ends of the wires are rotated relative to the package

0 (up and down from it) at (10 ... 20) °, the collet grip 13 is lowered to the lowest position. The next piece of wire is fed to the collet grip 13, which only passes it in one direction.

5 (up relative to the grip). The device is ready for the next cycle of operation, which begins after the next pack of steel has been formed and is fed by the pusher 3 to the binding position.

0 In the initial position of the device for twisting the ends of the wires (turned relative to the package) the cup 21 (see FIG. 3) under the action of the spring 22 and the forces of the cracks, neither by drawing the wire through the hole in the disks 24, is at the extreme position, as shown in fig.Z. When turning the twisting devices to the horizontal (working) position, the bending angle of the wire ends increases,

0 reaches 90 °, and the branches of the last piece of wire are pressed against the top and bottom edges of the bundle. Collet capture 13. The next piece of wire is fed, which is installed symmetrically with respect to the package, and turns on a drive for rotating the device for twisting the ends of the wires. When the sleeve 20 is rotated with the cup 21, the newly fed wire is twisted with the ends of the previous one.

In this case, the formation of a twisting wire node comes from the package.

As the knot is formed, it puts pressure on the disk 24, determines the compression of the spring 22 and the movement of the cup 21 relative to the sleeve 20. The force of preloading the spring 22 with the nut 23 determines the twisting step of the node. The torque to the cup 21 from the gear wheel 25 and the sleeve 20 is transmitted through the spline joint of the latter with the cup 21.

An example of the device.

A 4 m overlap is required for the packaging of 6 m long rolled products. Accordingly, the device contains 4 pairs of devices for twisting the ends of the wires installed under the common portal and on the metal structures of the base. In the intervals between the devices for twisting the ends of the wires and at the ends of the device, 8 vertically movable tables and 3 pushers are installed.

Each pair of devices for twisting the ends of the wires is provided with a path for the binding wire, including a mechanism for straightening the wire, a roller feed mechanism, knives and a feeding screw mechanism with a collet grip,

The housings of the device for twisting the ends of the wires are mounted on the brackets so that they can rotate at an angle of (10 ... 20) ° with respect to the working channel of the device and are equipped with common mechanisms for their rotation separately for the upper and lower rows.

The travel of the table is up to 300 mm, the travel speed is up to 0.1 m / s.

The movement of the pusher in the formation of packs - 300 m, taking into account the additional movement to feed the pack to the binding position - up to 600 m; travel speed — 0.1 m / s.

The feed speed of the binding wire with a roller feeder is up to 0.5 m / s.

The wire feed speed in twisting devices is (0.3 ... 0.5) m / s.

The time of twisting the knot is up to 5 s.

The technical efficiency of using the proposed device is determined by the ability to pack into tetrahedral packages of almost the entire assortment of long products, including round bars, with the guarantee of retaining the shape of the bag, which allows to solve the problem of mechanization of loading operations based on the use of cranes with electromagnetic grippers, stack the packaged rolled products , save the binding wire currently consumed on rigging clamps. The width of the package is limited only by the length of the applied cargo electromagnet, which makes it possible to increase the efficiency of use of the latter; simplifying the design and reducing the metal consumption of the complex of the packaging equipment, since the auxiliary operations of forming the package are performed with a smaller amount of rolled metal; Improving the quality and reliability of binding of a larger amount than in the well-known equipment, the chag of the braided wire and the wire are produced from the package.
