Description

Automatic wire binding machine for tying wire ties and the like, in particular for multiple wrapping around a tying point relates to a wire binding machine for on son crooked wire or strip materialb any Queraohnittea, straight or curved bundles of rods, from parallel juxtaposed or iah stumps grazing at any angle.

The bindings are made by dams the sa connections Parts of a piece of wire are wrapped around one or more times, the noose is then drawn and each individual loop and the two wire ends are grooved together. Through this the result is a tightly enclosing the item to be tied due to the multiple wrapping absolutely secure connection.

Wire connections that loop around the veine ligation point several times, mostly 2 times, have so far been made exclusively by hand. Because of the great resistance to breakage of these double compounds they are mainly used. The simple connection too is = is produced in band work. A lot of machines have become known, that can produce simple bindings. In one system, the twist is in the direction of the constriction. Dieu requires that the Well at least for the length of the twist has an abene area. Also there there are automatic machines that dispense the ends of the loops in a hairpin shape turn. With all machines, however, it is necessary that the Parts have to be pressed together beforehand by clamping rods, because the connection is self-contained cannot exert a pulling effect.

All machines that have become known since then that are used to tie together Turning wire is a complex process Mechanisums sua laying around of the wire around the item to be tied together. Either complicated lever and Gripper systems applied or sometimes with all kinds of difficulties a looping system that moves the items to be bonded vertically Wrapping in connection with Lebel-odeur gripper systems works. Before everything In the case of large cross-binding requests and diode systems, the work is long the Steurerorane are necessary, which negatively affects the work speed.

The object of the invention is to provide a wire binding machine see who can produce ties with single and multiple wraps, Without moving parts for the looping, grippers, levers or even sine are used Vereohiebebewege do * Tying goods are necessary. The one necessary for the binding Wire is automatically fed from a wire ring. Well that Looping has the twisting and As-with at the same time then pressing the material to be tucked together to follow. Due to the special kind of common scorching of the wraps and the wire ends inevitably remove the twisting, do * jade risk of injury during = transport excluded. The oblique arrangement of the Drillsange sus auflagetisdh results in a twist pointing inwards into the collar. If that Drillende in its inevitably caused location and size unrevealed or su long trained oein soulte, relates the possibility to Umbigen and to Machswchnieiden.

The gate part of the subject of the invention consists in dams the finir dan tying off necessary wire from a wire ring controlled by sine and thus on the j required wire length adjustable conveyor arrangement can be fed. That prior preparation of the necessary for the binding Wire piece is omitted daduroh. The operating aaon only needs to be tied Place Out on the Manahinentinch and hit it against an aneolag so that ee in the correct position for the setting process. Then just need the machine to be started by a foot switch, and all others Work steps are then carried out automatically by the machine. Immediately After the binding process has been completed, the item to be tied will lie free on the Machine table and can either be picked up or dropped on to the next binding operation All ties are finished and removed from the machine.

A f a common slide 1, which can be moved in a fixed guide 2 is stored, the tools are arranged so that you can guide the parts to be tied around.

Be wind diww the rotatable, with winwr Sohrägw vwrwwhenw guide pin 3, the two guide pins 4 and the cover 5 for the guide 2 firmly connected Interim lead 6.

In addition, the slide still carries the parting man 7 for parting of the run-in wire and a cutting knife 8 for trimming the drill ends, store short ends are desired. The actuation takes place via a pull rod 9 of the slide 1. The fixed guide 2 also carries the cutting sleeve 10.

The wire feed device consists of two mutually adjustable bearing arms 11 and 12 on which the displacement rollers 13 and 14 are grounded. One Compensation spring 15 worgt for elasticity in anprwwwdruok, and sine Insertion sleeve 16 results in straight wire entry into the pre-stroke rollers.

The drill pliers head consists of two pliers halves 17 and 18, the have conical lugs at the foremost ends so that they can be securely detached the drilling process is guaranteed by lut. The pliers are through during the drilling process the spring pressure of the spring 19 is closed.

Opening takes place inevitably by pressing on pins 20 and 21 ai. Ears 22 and 23. The drill jaws 24 and 25 support all drill pliers the formation of the line of sight and the subsequent drilling process. You and also designed and controlled so that the drill beacon 25 after the drilling process behind the opening jaw 24 and the drill end more towards the waist bends as it corresponds to the inclined position of the Drillaoh.

Right from the zontral wall 26 is the main drill body 27. In this main drill body 27, the drill shaft 28 is mounted. The drive takes place from veines engine tuber an oilrios on the drive pulley 29.

The dalton of the drill wave flew over a Kupling 30 and the shutdown Via an overload clutch with adjustable torque 31. A lever 32, the is scattered by the main controller 33, blocked during the start-up of the twisting wave the overload clutch so that the increased starting torque can be transmitted. suber sinon Lebel 34 and a grooved ring 35 flew the longitudinal displacement of the twist shaft 28 and dosait also the pliers head 17-18, and via another lever 36 and A grooved ring 37 is used to open and close the pliers head. During the Drilling progress is the lever 34 of a control curve on the main control shaft 33 released. The spring 38 Sbt during this time the pulling force on the twist shaft 28 and thereby allows to a certain extent ln adjustment of the loop to undercut tie-off cross-sections. A stop 39 on Hauptdrillkdrper 27 and a gene stop 40 us groove ring 35 are used to front the pliers head 17-18 Beginning of a new work cycle again in the zero position zenkreoht sua wire inlet bring su.

A push button inevitably interrupts the machine from running, if the zero position should be missed.

The 8toueras of the individual work cycles of the illustration example takes place see also part mechanically, e.g. T. electrical son the control shaft 33 aura. Dor drive takes place from the Metor via a drive disk 41, an intermediate shaft 42 and a clutch 43. From each intermediate shaft 42, a bevel gear and the coupling 44 are also the advance shaft 45 and datait the displacement rollers 13 and 14 are driven.

The feed speed of the wire when re-8ehlingen dois binding material is expediently chosen to be constant. If the binding cross-section is small, the Wrapping process ended faster than with a large cross-section. Correspondingly it behaves well if one or more umachlingang is inserted.

In order to avoid unnecessary idle times, the machine is designed in such a way that then the control shaft with the switching on of the wire feed via the coupling 44 is stopped by the coupling 43. The feed shaft 45 now defies sinon Chain drive 46 controls an adjustable measuring device, which is used to switch off the wire feeder the control shaft via the clutch 43 is maintained. Diezer intermittelerdned Drive the Control shaft is achieved by the following arrangement: Featured with t of the control shaft 33 is a flange 47 with a driving pin 48. Above is a Flanoh 49, which with a sliding bushing loses on the control shaft 33 sits. The flange 49 is moved in the direction of the arrow via a bevel drive and a freewheel 50 powered. On a further holder 51 which is located on the control shaft 33 Lot in 81ter 52 attached, which is via a worm gear 53 and a handwheel 54 concentric with the control shaft 33 is adjustable. A Bahalter 55 and a Schmalter 56 are firmly attached.

After switching on the duty cycle, the control shaft 33 settles moving. The Kitnehmeratift 48 can because of the built-in freewheel 50 the Mocken won Flanaeh 49 bia su Schater 55 drag along. This switch opens the Coupling 43 and thereby stops the control shaft. At the same time, however, it closes also the coupling 44 and sets the feed catfish in motion. About the chain drive 46 and the freewheel 50 with the attached Kagel drive now receives the flange 49 self-propelled and rotates k further in the direction of the arrow.

As soon as the switch 52 is touched, the wire connection is via the Coupling 44 interrupted again, and the 8tenue 33 at the same time, however, the coupling 43 switched on again. As soon as the driver seat 48 don lfooken van Flanroh 49 has caught up with Sehalter 52 again, a new towing process begins up to the zero position at the counter 56, where it will finally be stopped. Depending on whether you don distance between If switches 52 and 50 are reduced or enlarged, a smaller one occurs automatically or larger wire feed and finally in a shorter or longer period of inactivity the control shaft.

The working part of the described mzzchine is as follows: The in The wire ring chosen as an example in this case is placed on the machine table and pushed against the adjustable double stop 57, with mine centering to cement the twist axis.

Depending on whether larger or smaller end-of-line cross-sections are tied around should be, the stop must be adjusted to the Drillzohoo so that the center of the binding transverse housing committee comes to lie in the side of the drill tohee. Switching on the machine is operated with a foot switch, whereupon the control shaft 33 in Movement is set and the slide 1 with the loop 3, 4 and 5 in working position A brings.

During this time, the drill forceps are also aligned 17-18 on the gauze position. The twist shaft 28 is already through the lever 34 brought into the wnterete position ver termination of the preceding Arbietzysklauses will.

By briefly switching on the drive coupling 30 and blocking drer the downstream overload clutch 31, the twisted shaft is only berssoltlg in rotating movement until the squats 39 and 40 lie against each other. At the request the mock could trigger the overload clutch that has been released in the meantime 31, and a switch connected to this clutch switches the drive clutch 30 off.

In between, the driver pin 48 has the size from the flange 49 to dragged along to switch 53, from where au now shut off the control shaft 33 and the feed shaft 45 is switched on. The feed bells now cut don Wire through the cutting book 10, the intermediate guide 6 and the guide pins 4 gogen don start-up pen 3. where the wire pulls according to the approach angle the incline of this pin to form a spathe-like ring sit one or more next to each other lying Deformed turns. The wire feed is intermittently adjusted so that the beginning of the wire always runs out by approx. 40 mm over a large number of turns, so that this end can be corrected during the drilling process.

If the wire feed length set on the handwheel 54 has been reached, hold the switch 52 turns off the wire feed and the control shaft 33 turns on. On the Lebel 58 moves the slide 1 with the wrap-around factory eyes into position B. withdrawn. As a result, the still circling wire loop touts freely, has everything about the same amount of material to be bonded and is only cut off by that which has not yet been cut off The end of the wire is held in the cut-off hole. The twist shaft 28 is now flat lifted, and the clamp halves 17-18 close in the uppermost position in the white where the conical lugs touch within the wire loop.

In the meantime, the drill brooks have also moved into the areas shown in Fig. 3 position shown advanced. The naohate operation is the withdrawal of the Slide 1 into position 0. Dadurah will cut the wire from the cutting knife 7 Cut-off sleeve 10 separated. The now free blank is taken from the drill shaft 28 durah the spring force of the spring 38 nachg under pulled, with the same side Drill jaws 24 and 25 to run closer together. Fig. 4 digests this working phase, The spring 38 pulls the loop down so far that it is tight around the item to be tied has laid. The Twist shaft 28 under spring load, then during the twisting a shortening occurs of Drill in, and the head of the pliers must be accordingly can hike up with you.

The drilling process is initiated by switching on the drive coupling 30. So that the increased start-up joy from the downstream overload clutch 31 Can be transferred, this clutch is through the lever 32 ton of the store 33 temporarily blocked.

But nooh before the end of the twisting becomes the overload coupling 31 vider released and takes immediate action when the desired tension the twist is reached. A holder is connected to the overload clutch 31, which also holds the drive clutch 30 when responding.

The next work cycle opens the drill head 17-18 and leads the twisting wave down. The left drill jaw 24 is now withdrawn during the right drill jaw 25 is advanced an 8tUok, us then drill end in lie inside the ring (Fig. 6). Sopllet that by this setting process inevitably conditional drill end for a special case can be so long In Sohieber 1 a cut-off meter 8 can be accommodated, which against the ale counter knife Oiling drill jaws 24-25 cut away any part of the drill end.

In this case, the control cams for the drill jaws 24 - 25 must be changed accordingly.

Then shown in the drawing example of an automatic wire binding machine for single or multiple wrapping shows a combined electrical-mechanical Steering. Of course, all necessary tax movements can also be made run purely mechanically, electrically, hydraulically or puneumatically, as well as any combination of these types of control is possible.

The advancement of the wire during the wrapping process is not on give a pair of transport rollers. Ebensougt is a straight, controlled movement possible by means of a transport sledge.

The automatic wire binding machine can be used as a stationary table machine, as a mobile table machine, but also look for all mobile ones in the manner of eiDer Lzutkztso be designed as a suspended system. the latter version has the advantage that, especially with long bundles of bars, one should drive along the bundle and into the required spacing the bindings can attach.
