The invention relates to a method for producing multiply bound wire ring packages and an apparatus that operates according to this method.

According to a known method, a device for packaging wire rings is operated in such a way that that a plurality of wire rings guided in their middle on one that can be raised and lowered Support plate is pressed against one another without permanent deformation of the wire windings. Here will be the wire rings from a movable press jaw attached to a stand against one a Ringaufnahmcvorrichtung attached fixed jaw pressed. After that, the compressed wire rings with a clamping device or tied with wire on each side. When the wire rings are pressed together, the. individual turns not only pressed into each other, but at the same time the outer turns radially outwards and the inner turns radially outwards pressed inside, so that those on the support surfaces adjacent windings are damaged as a result of the frictional wear that occurs. Through this, that the wire rings are in frictional engagement with the support surface, becomes an additional one eccentrically engaging Kraftkoniponente effective, which is eccentric on the pressing device affects and tilts the Iilemente involved.

The aim of Krfmdimg is one procedure and one afterwards working device with which a rubbing of the windings on the support surface is largely avoided when compressing. This is achieved according to the invention in that the Wire rings are initially only pressed together so that they stick together without support, afterwards the support is removed and the wire rings then continue for the binding are pressed together. In this way, the last compression is on the binding dimension, at the diameter of the wire rings increases, the risk of removing the support removed from damage to the wire.

Raising the support of the wire ring package after creating at least two bindings, it can happen faster than the slackening off the pressing force. The pressing process can also take place immediately after the wire ring package has been supported be terminated.

To carry out the method, a device in which a plurality of wire rings above a table that can be raised and lowered by means of a movable press cross is a fixed method and device for production
of multi-bound wire ring packages

The wire ring press works as follows: When the switch 25 (FIG. 7) is switched on, the motor 26 drives the pressure medium pump 24. This pump sucks the pressure medium, z. B. oil, and presses it into the line 28. A safety valve 29 is connected to this line 28, which limits the oil pressure to a maximum of 140 atmospheres. The pressure medium flows from the line 28 through a changeover switch 30, which returns the pressure oil directly to the oil sump 27 if it is not consumed by the other consumers. After passing the switch 30, the pressure oil is fed through the line 31 to the consumers. To this end, the changeover switches 32 and 33 are connected to the line 31. When the machine is switched on, the changeover switch 33 is in the position shown in FIG. 7, while the switch 32 has been switched to flow by a pressure monitor 35 and the magnet M 8. The memory 34, which has a capacity of approximately 30 liters, is now filled via the line 38. After a certain pressure has been reached, for example 70 atmospheres, the flow of current to the magnet M 8 is interrupted by the pressure monitor 35 (D 3). A spring pushes the slide switch of the switch 32 back into the position shown. The safety valve 36 limits the pressure to 80 atmospheres, for example, if the pressure monitor 35 should not shut off the flow of the pressure medium through the changeover switch 32 as a result of an error. A manometer 37 connected to the line 38 shows the pressure of the pressure medium which also prevails in the memory 34. The pressure in the line 31 is indicated by the pressure gauge 82. - In the starting position for inserting the wire rings to be pressed together, the table 40 is in its uppermost position (FIG. 3). A mandrel lift truck, not shown, places several loose wire rings 70 on the table 40.

By pressing the push button DrI (Fig. 8), the relay R 1 is energized (z. B. 24 volts) and actuates the associated switch rl, which closes a circuit via the relay Rl, rl in which the magnet M 2 , this pull magnet M2 actuates the changeover switch 41 (FIG. 7), so that the piston 46 is displaced in the hydraulic cylinder 47 via the line 42, the throttle 43 and the lines 44 and 45 and the table 40 is thus lowered. In the changeover switch 41, the slide switch is shifted downward for this purpose, so that the slide part 48, the lines 44 and 45 and the lines

50 and 51 connects to each other. Through the line

51, the pressure medium flowing back from the cylinder 47 is fed to the general sump 27.

The table 40 (Fig. 1) is connected to the hydraulic cylinder 47, piston 46, the Winlcelhebeln 52 and 53 and the connecting rod 54 raised and lowered. For this purpose, the angle levers 52 and 53 are rotatably mounted in the frame 20 with the bearings 55 and 56. Through the double joint 58, the piston rod 57 and the connecting rod 54 are with the lower arm of the bell crank 52 connected. The joint 59 connects the connecting rod 54 with the lower arm of the angle lever 53. Through the joints 60 and 61, the upper arms are the angle lever 52 and 53 connected to the table 40.

After pressing the push button Dr 1 and the electrical and hydraulic shaving operations described above, the table 40 moves downwards until a switching cam 62 (Fig. 1) on the switching rod 64 actuates a switch 63 and thus the switch St (F i g. 8) opens. This releases the relay Rl, rl so that the magnet Ml is de-energized. In the changeover switch 41 (FIG. 7) the control slide is pushed back into the middle position by a spring. The switching cam 62 is arranged in such a way that the table stops when the wire rings 70 arranged in dash-dotted lines are in the center of the press crosses 67, 68.

ίο By switch 63 and switching cam 62

'The switching contact 52 (FIG. 8) is closed at the same time. This actuates the relay /? 3, r3 as well as RIl, rl 1/1, rl 1/2, and the MagnetMl picks up. The pull magnet Ml moves the control slide in the changeover switch 33 in such a way that the slide part 71 connects the lines 31 and 72 as well as 74 and 73 with one another and the pressure medium flows into the cylinders 75 and 76 and moves the pistons 77 and 78, whereby the left press cross 68 ( Fig. 1) is driven with the carriage 22 against the right press cross 67. Here, the wire rings inserted between the compression curves are pressed together. The pressure medium pump 24, which can increase the pressure to, for example, 140 atmospheres until the safety valve 29 responds, provides the required pressure. A line 83 is connected to the line 72 and a memory 84 and the pressure monitors D 1 and D1 are connected to it. The pressure switch D 1 closes when z. B. 70 atü the switching contact d 1 (F i g. 8), so that the magnet Ml attracts again. The table 40 is now, since the pressure of e.g. B. 70 atü is large enough to hold the wire rings 70 between the press crosses 67, 68, further lowered until it reaches the lowest position. When the table arrives in the lowest position, a switch cam 69 on the switch rod 64 can release the contact r4 / l. But it is also possible to hold the table in the lowest position under pressure and later to close the contact dr 3/4 by pressing the push button Dr 3, so that the relay /? 4 responds and contact r4 / 2 is closed and contact r4 / l is opened.

In the further course of the work steps, contact r4 / l is closed again by opening contact SIl. The pressure in the cylinders 75, 76 is meanwhile increased further until the pressure switch D 2 z. B. responds at 100 atm and releases the switching contact dl , so that the magnet Ml is de-energized and the control slide of the switch 33 returns to the starting position by spring force. The pressing force on the press crosses 67, 68 is retained, since the leakage losses are compensated for by the memory 84. While the cross presses compress the wire rings, a suitable steel band is used to create a bond on each side of the wire ring press. Then the push button Dr 1 is pressed.

By pressing the push button Dr 2 a relay /? 5, r5 actuated and one of the magnets M 3 or M 4 attracted. The magnet M3 is attracted when the switching contact 53 is closed, while the magnet M4 is attracted when the switching contact S4 is closed. The switching contacts 53 and 54 are connected to a slide switch which is switched over shortly before reaching an end position of the press cross. Such a slide switch is preferably on the right warehouse

The ejector is actuated when it reaches the top. As a result, the table 40 position is another limit switch, which moves the Konaus up to its lowest position in order to briefly close the clock 59 and thus support the custom-made wire rings. At the same time gnet MS is put on. In this case, the relay is left Preßkreuz 68 by tightening of the magnet 30 Ri2 rl2 and holds the magnetic MS under chipboard M 6, switching of the control spool of the switchover voltage. The magnet MS moves the spool lers 33 and by the difference in the forces that the switch 41, as already described above, act on the two sides of the piston 77 and 78, and causes the table 40 in the uppermost Stelin to the starting position left (Fig. 1) moves back in which a limit switch has moved contact 510. Here, the pressure medium is released from the 35, so that the magnet M5 is de-energized and the left parts of the cylinders 75 and 76 go back via the control slide of the switch 41 in the zero line 72, the slide part 90 of the hydraulic treatment.
