Device for binding metal wire coils.

The invention relates to a device for binding products made in metallurgical factories Metal wire spools.

Ss such devices are known in which pliers parallel to the axis of the coil outside and, can be moved within the same so that they form a loop around the coil with a binding wire, whereupon the two ends of this loop are twisted together.

Apparatuses are also known which make this binding by having two connecting links which are parallel to one another apply, one outside and the other inside the coil, whereupon they attach these links to the two Twist the ends of the coil

Other known devices have guide slides, in which the wire is pushed forward towards a twisting head.

309849/0377

These machines have a certain number

of disadvantages. The time to apply the link is generally quite long, i.e. not very compatible with the. Production speed of the coils to be tied.

The advance of the binding wire into the foot

Slipping causes the same to solidify, which can cause the wire to break while it is tied. This Disadvantage can be caused by using an annealed wire can be avoided, but binding is then more expensive.

Furthermore, the guide rods experience a.

heavy wear and tear, and the systems for opening the chutes Releasing the link and tightening it on the spool are involved and expensive.

Finally, there is mechanical strength

the bonds obtained and the appearance of the twists are not very satisfactory. The ones that protrude too far and are not unbent Namely, ends of the twist can cause accidents and make handling of the bound bobbins difficult.

In the known devices, the

Coil placed horizontally on a receiving cradle by a hook conveyor, and a carriage movable in the longitudinal direction prints it against the binding system, with an inclined plane provided for the removal of the spool after binding.

These devices operate rather slowly and therefore not entirely satisfactorily.

The invention aims to overcome these drawbacks

to remedy this by providing a device which allows the coils to be tied in a quick and secure manner.

The device according to the invention for binding metal wire coils with means for applying a connecting link on a spool and means for twisting this link is characterized in that the means for twisting the connecting link has at least one mandrel, which can be given a translational movement and a rotational movement, and which has a head receiving the two ends of the link and at least one backing plate which is positioned opposite the head of the mandrel to hold the link during rotation of the mandrel.

The device according to the invention still has

Means for handling the bobbin 7, which below under Reference to Pig. 17 are described *

These means comprise two rods 20 which hold the bobbin 7 approximately horizontally and are attached to two pairs (of only one of which is visible) of angle levers 65, 66 which are non-rotatably connected to two horizontal shafts 67 attached to the frame of the device.

These two shafts 67 are non-rotatably connected to two gear wheels 68 that are in engagement with one another.

The lever 66 has an end portion 66a.

provided, which is connected to the piston rod of a hydraulic working cylinder 69 supported on the frame 1

By actuating the working cylinder 69, the rods 20 can thus be moved into the upper (shown fully extended) Position to support the coil 7 or in that with 20a. designated lower position are brought.

The working cycle of this device is as follows:

At the beginning of the work cycle there is the

the moving plate 3 supporting compression carriage 11 at the end of the Frame 1 of the machine, as in Pig. 1 shown, and the support rods 20 are in the lower position 20a (Pig. 17).

The tie arms 13 are in Pig. 2 closed position, with its pincers 33 (Pig x 8) open are.

The 3? Ragschlitten 15 of these arms 13 and the

Drive bushing 16 of the carriage 15 are in their (in Pig. 15 dash-dotted line shown) starting position on the

309849/0377

left end of shaft 17, and the piston rod of the working cylinder 18 is completely withdrawn.

The connecting rod 48 between the socket

43 (Fig. 6) and the mandrel 27 rests against the stop 40, so that the thorn 27 opposite that in Pig. 6 is behind. Furthermore, the twisting tongs 52 are spread apart (position 52b), and the movable plate 54 is located calibrate at 54a.

Finally, the piston rod of the working cylinder 45 is retracted to rotate the flywheel 39 (Pig. 9).

A metal wire coil 7 hanging on a hook 8 is then placed across between the box 10 and the compression plate 3 (Pig. 1).

The successive steps of upsetting and binding are as follows:

a) The lifting cylinder 69 of the! Pragstangen 20

(Pig. 17) is operated in such a way that these are brought into the upper position in which they support the coil 7.

As a result, the bobbin 7 is raised slightly above the feeder hook 8 (Pig- 14)

b) One operates the upsetting cylinder 5 (Pig. 1 and 17), whereby the rods 20, the coil 7 and the Carriage 11 can be moved in the direction of the box 10.

The cutout formed in the viagen 11 and the plate 3 enables them to close along the hook 8 slide, which remains immobile.

The coil is thus compressed by the plate 3 on the fixed plate 2 serving as a stop.

During this upsetting, the diameter of the coil 7 increases somewhat, making its axis relative to the Poor 13 comes higher, which could interfere with the proper course of the binding process.

To avoid this danger, the

Pressure in the hydraulic ram 69 (Pig. 17) increased somewhat to lower the support rods 20 about the axis of the spool attributed to their original height.

15), which removes the slide 23 from the support slide 15 of the binding arms 13.

The links 22 then twist the arms 13

around the axes 14 so that the arms open and those in Pig. 3 assume the position shown, the two corresponding Links are crossed,

e) The working cylinder 51 (Pig 6) is actuated in such a way that it runs through about half of its total stroke, whereby the flywheel 39 and the mandrel 27 are removed from the stop 40, with the born between the binding arms 13 (Pig. 7) occurs.

During the translational movement of the mandrel

presses the peder 55 on the plate 54 and transmits the translational movement on them. The plate 54 in turn presses on the arms 52a, whereby the twisting tongs 52 closed and the both sections 28a of the counter plate 28 are combined.

f) The working cylinder 18 is actuated (Pig

15) »which the support carriage 15 of the binding arms 13 a translational movement issued and the eight arms 13 transferred to the other side of the coil 7, on them in the visible in Pig * 4 To take position.

Four arms walk during this movement

13 through the inside of the coil 7 »while the other four pass by outside, each taking a link with them.

g) The binding arms 13 are by means of the working cylinder 25 (Pig * 15) closed, making them into the Pig. 5 visible position come and the ends of the connecting links to be crossed *

The eight links 34 now include

completely the coil 7 and are in the grooves 58 (Pig. 13) of the Counter plates 28 introduced.

h) The working cylinder 51 is actuated again, so that it ends its stroke, whereby the head of the Mandrel 27 of the counter plate 28 is approached. During this movement

309849/0377

The connecting links 34 enter the grooves 57 of the head of the mandrel 27 (Pig. 10-13).

The eight twisting heads are then ready for use.

i) The binding tongs 33 of the connecting link 34 (Fig. 8) are cöhet in order to release it.

j) The working cylinder 45 is actuated (Fig.

9) »which rotates the toothed flywheel 39 and the mandrels 27. The gear ratio of the movement between the flywheel 39 and the drive sleeves 42 of the mandrels 27 is chosen so that the latter rotate by a little more than one revolution.

At the beginning of the rotation of the mandrel 27 will be

the links 34 on one side of the spool are cut off by the knives 63j 64. The knot is formed during the rotation within the central recess 61 of the mandrel 27 and fills this gradually off.

At the end of the rotation you get the one shown in Fig. 18 shown twist with bent ends.

k) The binding arms 13 are opened by means of the working cylinder 25 (Pig · 15).

1) The arms 13 are returned to the other side of the spool 7 by means of the working cylinder 18 (Pig. 15).

m) The eight twisting heads are made using

the working cylinder 51 is returned to its starting position by a translational movement.

n) The Bindearrae 13 are by means of the work cylinder 25 closed (Pig 15)

ο) The mandrels 27 v / ground by actuating the

Working cylinder 45 (Pig. 9) by rotating it into its starting position returned.

p) The two support rods 20 are raised by means of the working cylinder 69 (Pig. 17).

q) By means of the upsetting cylinder 5 (Pig 1)

the upsetting carriage 11 and the coil 7 lying on the rods 20 are brought back to the vicinity of their starting position.

The coil 7 now takes the one in Pig again. 1 visible position, and its elasticity prints

the links 34 strongly against them

r) The two rods 20 are on about the

half stroke of the working cylinder 69 (Fig. 7) lowered to the bobbin 7 to put on hook 8.

s) The decrease in the upsetting cylinder 5 is

finished, and the spool 7 is by means of the hook 8 of the feeder discharged

The upsetting and binding device is then ready for a new work cycle.

The successive work steps to the

Upsetting and binding can of course by means known per se can be done automatically, with the command. to trigger of the work cycles of the door direction by the conveyor to the supply is given to the coil

In the above manner, a metal wire coil was made compressed and tightly tied by attaching to each of their The ends of animal twists of the type shown in FIG. 18 were formed, which are offset from one another by 90 °.

The twists according to the invention can

withstand significant residual forces generated by the compressed coil can be exercised and can reach 45 suns. You allow therefore, to handle the coils in complete safety.

They also have short bent ends, which makes handling the spool by bridge cranes common Cranes etc. are made easier and the risk of accidents is avoided due to long protruding ends

The device according to the invention has even more advantages:

The counterplate «J28 first of all enable that

To attach link 34 and adjust its position precisely, before it comes into the grooves 57 of the head of the mandrel 27. Then they hold the link 34 during the rotation of the Dorns. The counter plates 28 thus ensure a very secure twist, in particular by the risk of a wrong switch off the previous position of the link.

Your _v retraction after the formation of the twist allows Bindegliederr ^ 54, to stretch under the action of Bestkräfte the coil 7, whereby the twist
