"Machine for winding wire rolls and other articles and winding device with appropriate

Use"

The present invention relates to the winding of wire rolls or other articles.

According to a common method, rolls of wire are made with winding bars wrapped as a tie from a spare roll. This wire is straightened beforehand by placing it under tension over guide rollers run IHOt and then use it as a tie on the article to be wrapped forms and finally cuts off and twisted at its ends. Before the wire is cut, it is usually done again turning in reverse to remove the excess unrolled To grasp the wire and place a corresponding tie on the winding rod as a tie To be able to apply tension.

This method has several disadvantages. Because the twist runs from the ends of the tie to the surface of the article, In addition to tension, the rod is also strong twisting forces exposed, which reach their highest values at the end portions near the roll or other article. This results in Frequently during the wicking and especially during the transfer Fractions that are a major disadvantage. About that In addition, this method is relatively expensive to use.

The present invention is intended to eliminate these disadvantages will. It relates to a machine for winding wire rolls or other articles, which is characterized by having at least possesses a guide surface in order to oppose a roller or another Article to put a staff, which consists of a directed and on a suitable length cut metal rod as well as

directed means for bending this rod around a cross-section of the Role exists. This will roughly have a hairpin shape with the end sections formed this winding rod in order to be able to apply the tension desired for the winding rod. as well as a device to with this the united end portions of this winding rod from the surface to twist the hell towards the free ends of the rod.

The outward twist of the article to be wrapped ensures that the risk of breakage of the winding bar is reduced to a minimum, because the end portions of this bar are exposed to tensions that grow towards their free ends.

According to a further feature deflectors are provided around the end sections to be able to center and guide the winding rod before it is taken over by the twisting device.

The invention also has a device for Use of the machine defined above for winding wire coils or other items that are individually transported by a transport device, e.g. with Ilaken. The system is characterized in that it eliminates a carriage on which the machine is mounted, which moves parallel to the displacement of the transport device synchronously with this back and forth to a winding cycle with the machine perpendicular to the direction of displacement " the transport device can be moved to opposite the Bolle or any other article to be wrapped, a suitable active position to be able to take.

According to another characteristic, the winder has plates arranged parallel to one another, which are of such a nature as to daefl you can compress the roll before winding.

According to one embodiment, the winding machine is designed so that they simultaneously have two or more winding processes on diametrically opposite ones Sections of one and the same role.

It can be FIuQ- or Hartetahl «However, under no circumstances should it be hard lie above that of the braht to be wrapped so that it does not deform will be prevented or notches.

The feeder O

has a magazine m for receiving individually

superimposed rods b, a support surface on the magazine floor for the lowest rod, a vibrator adapted to the magazine, which ensures that no equilibrium w "is established between the rods b, which makes it easier for the rods to slide down. The magazine has des another pusher t, which is actuated by a cylinder in order to take over the respective lower S ^ ab as well as drive rollers g, which are provided for transporting this rod outside of the magazine.

The outside of the magazine m of the distribution device B transported Rod b is driven by pusher rollers 1 when it arrives at machine A taken over, which are mounted on the substructure of the machine.

The winding machine has two guide plates 2 and 3 »between dexn the winding roll C is arranged. A connected to the plate 2 nose 4 allows the correct attachment of the S ^ abs b compared to the cross section of the roll to be wound. The rod b can through the plate are transported through, and the rollers 1 take a position which determines the starting position for the wrapping process.

With the help of a claw 5 and its counterpart 6 -of which the Claw 5 over the cross-section of the role and the counterpart 6 by one Can move the joint axis 7 around - the rod b can be bent, so that it can adapt to the outline of the cross-section. The claw 5 is operated by a cylinder piston rod 8, while the counterpart 6 is actuated by a lever arm 9, for its movement as well a cylinder provides (the cylinders are not shown).

The machine also has a twisting device or a winding head 10, which by a mechanism with. one Hydraulic cylinder 11 is driven with a pinion and rack via a bevel gear. There are deflectors on both sides of the winding head 13 for centering and guiding the end sections of the winding rod *) provided prior to their introduction into the end winding 10.

The effective counterpart 6 and the winding head 10 are eit the plate tied together. The distance between the winding head and this plate is such that the twist near the end of the cone C comes into play, causing the winding of lesser pods of strength is made possible. The axis of the winding head 10 and the joint axes of the counterpart 6 are located in one plane. Claw 5 is from the plate 2 worn.

In this embodiment, the approach of a second winding head 10 'shown as an extension of the head 10. A second unit of rollers and claws or counterparts is combined with this second winding head, and this unit is made by the same mechanism 11 driven to simultaneously perform a second winding diametrically opposite to the first winding. A second Distribution device analogous to device B, is for the supply of bars provided for the second winding device. This device is arranged at a corresponding height for the second device.

If the machine is in the position shown in Fig. 1, first the counterpart 6 and then the claw 5 actuated, whereby the Formation of the angle bar is made around the relevant cross-section of the roller C around. During their closure press the claw and the counterpart 6 the winding rod against the deflector 13, whereby the end sections of this winding rod are bent as shown in Fig. 2 can be seen. The pressure of the claw and the counterpart on the bent parts of the rod produces the desired result for this rod Tension. The curvature of the end sections changes up to theirs

Claw 5 and the counterpart 6 and the winding head 10 play a particularly important role for the quality of the winding.

The end of the claw 5 has a V-shape and represents the complementary one Receiving part 15 of the end l6 of the counterpart. The also one V-shaped deflectors 13 center and guide the end sections of the winding rod before they are inserted into the rollers 17 of the winding head introduce. When this winding head is turned, the is then shifted to twisting tension applied to the united end portions of the winding rod from the surface of the roller to the free end of the rod. There is a risk of the Wickelstaba breaking in the area of the roll thereby reduced to a minimum, because the torsional stresses are strongest at the end of the united end portions of the winding rod. In addition, the inner winding in the role switches the dangers a notch between the rollers.

Figures 4 and 5 are schematic diagrams of a facility for the Winding of wire coils that are individually suspended from hooks of a transport device.

1 The rolls C brought by this transport device must Be squeezed together before wrapping so that their faces are parallel will.

For this purpose, the winding machine just described has 2 movable ones vertical plates arranged parallel to each other * The machine is mounted on a frame 20, which itself is mounted on a chassis 21 is arranged. The chassis 21 can move in the direction of displacement move the transport device back and forth synchronously with this to carry out a winding process.

The frame 20 can be moved at right angles to the direction of displacement of the transport device, so that the machine A is in a direction to the winding roll suitable active position can be brought.

009808/028 5

In this implementation example, two are carried out at the same time Winding operations are provided, and two distribution devices B are mounted on the chassis 21, so that the two winding operations run in two diametrically opposite positions of the roller (see Fig. 5) · On Figs. 4 and 5 the devices with the Claws and counterparts and the winding heads are not shown.

Figs. 6 and 8 show the process of compressing the roll C before the wrapping process again. With the help of a cylinder 22, the frame 20 is pushed under the roller and the roller with the plates the winding machine framed.

By means of a cylinder 23, a following movement can be exerted on the two plates 2 ', 3' in order to bring the roller C into the center of the hook K, so that a margin is left on both sides of the roller to prevent a lack of synchronization between the To be able to absorb the speed of the transport device and that of the chassis 21. As a result of such a lack of synchronization, the roller could be shifted to one side or the other during compression and wrapping and could no longer be in the center of the hook without the roller reaching the ends of the hook. The clearance provided on the hook enables a constant displacement speed to be selected during the process, as a result of which a reference measurement linked to the speed of the transport device is avoided.

The plates 2 'and 3' are displaced in the sequence determined by the cylinder 23 and a second cylinder 24. The plate 2 'is locked by the cylinder 24. The pressure exerted by the cylinder 23 displaces the plate 3 'up to a fixed stop 25 and brings the roller into a position with a clearance on the free side of the hook end K. The contact of the stop 25 with the plate 3 ¹ causes the plate 2 'to be unlocked, thereby creating a clearance on the hanging side of the hook. The roll is then compressed and the winding process can begin. This

The process runs according to the preceding instructions via the Working principle of the winding machine A from while the chassis moves forward synchronously with the transport device. After completion of the winding process, the plates 2 * and 3 'of the Role released, the frame 20 removes the machine from the roll and the chassis 21 runs back to take on the next role.

All the processes mentioned are controlled automatically, e.g. with the help of a program.

P Figs. 9 and 10 show a modification of a winding machine, in which two claws or pairs of counterparts are provided, with each other the one - 30 - under the roller C and at right angles to the rod b and the others - 31 - are above the cross-section of this roll and can translate in a direction perpendicular to that of the pawls 30.

The winding head 10 is the winding head of the example in FIG. 1. The claws 30 press the rod b against the roller and form it

a hairpin shape while the claws 31 close this shape, by pressing the section ends of the rod against the deflectors 13.

In the modification of Figs. 11 and 12, two bars become two "Claw pairs 32 and 33 used to perform two twists, by joining the ends of the bars.

Of course, the invention is not limited to those described and shown winding processes limited. These were only given as an example.

So the winding machine can be arranged in such a way that at the same time four wrapping processes at an angle of 90 ° to each other or any number of wrapping processes as required can be made. The machine can with the shown Rod feeding device, but also through any other directional
