Definitions

• the invention relates to a method for binding bundled objects, in particular cable pieces, in which a bundle is held together by means of at least one binding material tied around this, and to an associated device and also a binding material.
• electrical cables in certain applications they are cut into pieces of a length, for example between 20 and 200 mm, by a cable reel, the ends of the insulation sleeves are loosened (stripped) on both sides and subsequently bundled and packaged by hand . Before these cable pieces are used, the bundles are again loosened by hand and the cable pieces are used for electrical connections, for example in circuits or the like.
• Binding materials are known which are made of plastic and have an eyelet at one end into which the binding material, which is in the form of a cord, is inserted with perforations provided on the circumference over its length. This perforation ensures that the binding material is fastened barb-like in the eyelet when tightened around a bundle.
• this binding material can be detached from the bundle only with great difficulty and is not suitable for mechanical bundling.
• the present invention was based on the object of providing a method and a binding material for binding bundled objects, in particular cable pieces, by means of which a bundle of elongated objects can be mechanically bound together in a simple manner, the binding material holding this bundle together is inexpensive to manufacture, ensures that the bundle is held together permanently and is nevertheless easy to release by hand.
• the binding material should lie more delicately around the bundle and have no protruding ends.
• the object is achieved in that the binding material having an opening at one end is carried out with its other end after wrapping the bundle through this opening, that consequently a tensile force which holds the bundle together creates this binding material and it at the location of the Opening is bent back to form a folded edge, and that to generate static friction with this folded edge remaining end of the binding material is pressed against the binding material placed around the bundle.
• FIG. 1 is a side view of an inventive device for tying a bundle

• FIG. 4 shows the device according to FIG. 1 when the binding material is introduced
• FIG. 7 shows a partial view of the bundle with the binding material bound around it.
• the device 10 consists essentially of a stand 15, a laterally vertically arranged guide rail 16, a height-adjustable slide 18 with a bracket 17, a feed device 20 for feeding the binding material and a processing device 30.
• the stand 15 has a receiving head 13 for a respective bundle 11, which is provided with an upwardly open semicircular opening 14 'and with a guide groove 19 surrounding the latter.
• This guide groove 19 extends to the bracket 17 and it is continued in the latter in a downwardly open semicircular recess 21.
• the slide 18 laterally has a rack 22 which engages with a pinion 23 which is rotatable by a drive, for example a stepper motor, and the height of the slide is thus arranged.
• the feed device 20 for the binding material has two rotatable rollers 24 arranged axially parallel to one another, between which the binding material is guided. Upon rotation of the rollers, at least one of which is driven by means of an indicated rotary drive 28, the binding material is introduced through a guide slot 26 and through a through hole 29 approximately tangentially into the opening 14 'and is continued there in the guide groove 19.
• the processing device 30 for binding the binding material has a pulling device which consists of two rollers 32 designed as toothed wheels, which are also operated by a rotary drive (not shown in more detail) and are designed to apply a predetermined pulling force to the binding material passing between them ⁇ exercise material. Furthermore, this processing device 30 is assigned an approximately tangential to the opening 14 longitudinally movable slide 33 with a guide head 33 'and an approximately perpendicular to the guide slot 26 up and down sliding knife 35, the latter for driving a toothed rack 38 and an engaging with it Gear 39, which is driven by a rotary motor, which is not illustrated.
• the carriage 33 is connected by a dashed line clear articulated lever 34, which is pivotally mounted at the lower end via a rotary bearing 3 1 on the stand 15 and has a guide slot 34 ', in which a cam 35' attached to the cutting knife 35 engages, through which when the knife is moved the articulated lever 34 is pivoted and the carriage 33 is accordingly moved longitudinally.
• the articulated lever 34 is designed such that the knife 35 and the slide 33 are either moved towards or away from one another.
• FIG. 2 shows a schematic representation of a feed station 50 transporting the bundle 11 to the device 10 and a cassette 60 in which the binding material is rolled up.
• Cable pieces or the like are usually stacked into a bundle 11 after the machine has been cut off and stripped on both sides in a trough 51 which is indicated as indicated.
• a robot-like gripper pliers 55 grips the bundle 11 formed in the trough 51.
• a transverse slot is provided in the trough 51, in which the two grippers 56 grasp the bundle and insert it into the opening 14 'of the device 10 and hold it advantageously during the binding.
• the gripper 55 is pivotally held on a carriage 52, which in turn is guided in a longitudinally displaceable manner via a drive 57 along a guide track 53.
• the bundle 11 can be inserted or removed from the opening 14 'by means of a combination movement of the pliers 55 in a conventional manner.
• the device 10 is illustrated from the rear with the various stepper motors indicated above.
• an endless film band is provided for the binding material 40, in which the band pieces 42, which are each used for a bundle 11 to be bound, are formed one after the other in the endless film band.
• the respective band piece 42 has a tongue-like constriction at one end 42 'and at the other end 42 "it is somewhat expanded and has on the one hand an opening 44 for receiving the end 42' and on the other hand a further hole 43.
• the foil tape is preferably made of polyester; in principle, however, it can also be made from another plastic or a metal foil. For the rest, the strip material 40 is punched out of a full strip 40 ', shown in dash-dot lines.
• the binding material 40 which has an opening 44 at one end 42 ', is passed with its other end 42 "after the bundle 11 has been looped through this opening 44, on which a tensile force which holds the bundle 11 together is generated and applied the opening 44 is bent back to form a folded edge, and the remaining end 47 is pressed in a releasable connection against the binding material placed around the bundle in order to produce static friction at this folded edge.
• this bracket 17 is arranged in relation to the stand 15 in such a way that after the carriage 18 has been moved downward into a first predetermined position — as shown — it is shifted, thus opening an all-round opening 14 ′ from the semicircular opening 14 ′, and the guide groove 19 consequently extends around this opening.
• the binding material 40 with the tongue-like front end 42 ' is guided by the feed device 20 from the cassette 60 through the through hole 29 into the guide groove 19 and all the way back to the lower end of the opening 14.
• the opening 44 of the rear end 42 "of the inserted tape piece 42 comes into overlap with the through hole 29 in the receiving head 13, the tape feed is stopped.
• This tape piece 42 of the binding material is dimensioned in its length such that its front end 42 'after the The tape has almost reached this opening 44.
• Bundles 11 of this type with different diameters can thus be used without the device 10 being specifically set for a particular diameter and tape pieces with different lengths being required In the example shown, the outer diameter of the bundle is approximately half that of the opening.
• the bracket 17 is pushed further down to the second predetermined position shown.
• This causes the front end 42 'of the band piece 42 to be pushed through the opening 44 and further between the two rollers 32 which are designed as gear wheels, which advantageously already rotate in the direction of the arrow when the band piece is brought in and grasp and pull the latter until it does so Bundle 1 1 with a predetermined tensile force, as shown, constricts.
• a slip clutch not shown in more detail, which disengages at an adjustable load torque and releases the rollers from the drive.
• the cutting knife 35 and the slide 33 connected to it via the articulated lever 34 are moved against the band piece 42.
• the guide head 33 'of the slide 33 which slides directly under the end 42' of the slide causes the front end 42 'of the slide to bend until it forms a folded edge 46 in the opening 44.
• the end of the strip 42' is subsequently removed from the slide 33 at the cutting edge 48 cut off and the remaining end 47 pressed into a further hole 43 of the other band piece end 42 "by the pin 36, which also moves into this, whereby this end 47 is held therein.
• a recess 49 is provided in the receiving head 13, into which the pin 36 can be pushed.
• the cutting edge 37 also protrudes next to the pin 36 on the cutting knife head from the end 42 "from the following piece of tape.
