Definitions
- the invention relates to a method according to the preamble of Claim 1 and a device according to the preamble of the claim 3rd
- Such a method and such a device are known from the DE 12 99 548 A1 and DE 24 50 373 A1 are known. There are below a gap, the first and a second conveyor line separates from each other, a pair of pliers and a fly knife arranged, which is either a separate, through the open Forceps that can be moved through the pliers (DE 12 99 548 A1) or can simultaneously form a pair of pliers jaws (DE 24 50 373 A1). Each cycle begins with the bottom of one vertically from top to bottom fed film web in the Pliers are clamped before a cuboid to be wrapped against the film web is pressed.
- the one used in this known way for enveloping cuboids Foil is made of plastic such as PVC or PE and is therefore sufficiently smooth and tear-resistant to in the manner described across the bottom, front, and top of each box to be able to slide, the relative speed between Foil and cuboid on the underside and front just as big, on the top, however, twice as large as the speed of movement of the cuboid.
- the resulting frictional resistances are only manageable if the cuboid even as the film is smooth.
- the known ones described are suitable Procedure and device not.
- DE 11 70 859 A1 describes a device for wrapping around Cuboids known, the three arranged one behind the other of the Having cubes of conveying tunnels to be passed through one after the other.
- the first production tunnel has a transverse gap, through which a sheet of wrapping material passes from above is fed such that its lower end below one Bottom plate of the tunnel, and her cutting the track The free upper end above a cover plate of the tunnel is arranged. Then a cuboid to be encased in the first Production tunnel moves forward so that it is with its front puts on the track section and takes it, so that it forms thighs that also extend to the underside and to the Place the top of the cuboid and protrude to the rear.
- first and second production tunnels have gaps in the cover plate and the base plate through which initially a driver of an endless upper conveyor immersed in the second conveyor tunnel from above while doing so presses the top of the web against the back, and then correspondingly one with a lower endless Conveyor rotating carrier from below into the second Production tunnel intervenes and the lower overhang of the railway also pushes against the back of the cuboid.
- the Cuboid first from the driver of the upper conveyor and then pushed forward by the driver of the lower conveyor. So that the latter can reach the cuboid, the lower conveyor must temporarily driven at increased speed.
- cuboids can also be wrapped, which are not particularly smooth, and can be also not particularly tear-resistant wrapping material, for example Use wrapping paper; the device is complex and takes up a lot of space.
- the two conveyor lines are there arranged at right angles to a main conveyor which is of Insulated bales of cuboids.
- the first Conveyor line can be raised and lowered to every machine cycle to take over a cuboid from the main conveyor and into To promote direction to the second conveyor line.
- the second conveyor line is as a whole towards the first conveyor line adjustable to and from this, and the conveying direction of both Conveyor routes are reversible.
- the machine has a pair located to the side of the gap Stand in which a driver designed as a winding roll stored and guided up and down.
- the driver of the known device dips through the wide open gap down, grasp that End of the web held there, winds a web section and returns to its upper end position. Then will the web separated below the gap, so that it from the driver hanging loosely through the gap.
- the second conveyor line approaches the first one by the one it is moving towards Take over cuboid. Its front side bumps into the vertically hanging track section, which is used for locomotion of the cuboid is gradually handled by the driver. As soon as the cuboid has passed the gap, it will again wide open and the driver dives with him trapped web end down through the gap where he releases the end of the web.
- the invention has for its object a method and a device for wrapping cuboids, in particular bales of insulating material, with a web of wrapping material, in particular Paper to be designed so that given Dimensions of the cuboid shorter machining times can be achieved are and the device effort is reduced.
- cuboid 1 With the device shown are approximately cuboid Insulation bales, hereinafter referred to as cuboid 1, wrapped with a sheet 2 of wrapping paper.
- the Lane 2 is first on the front 3, then on the Top 4 and bottom 5 and finally to the back 6 of a cuboid 1, with web ends at the rear 6 form an overlap 7 and glued together there will.
- the web 2 is preferably so much wider than that Top and bottom 4 and 5 of the cuboid 1 that lateral protrusions arise, which are then folded over to the Cover long sides 8 of the cuboid.
- the cuboids 1 at relatively short distances from each other in the direction of arrow 9 in Figure 1 by the device shown conveyed through.
- the device has a frame 10 which forms a tunnel. To this leads a conveyor line 11, on each one Cuboid 1 moved by a slider 12 in the direction of arrow 9 becomes.
- the slide 12 works intermittently; he will each from its front one indicated in FIG. 1 with dashed lines Position in the rest position drawn with solid lines withdrawn.
- a second conveyor line connects to the first conveyor line 11 13, with a between these two conveyor lines with respect to their direction of conveyance (arrow 9) transverse gap 14 remains free.
- Barriers 15 are arranged, each of which is a cuboid 1 stopped is before he is taken on the second conveyor line 13 becomes.
- a third conveyor line connects to the second conveyor line 13 17 on, flaps 18 on both sides for bending of the lateral protrusions of the web 2 mentioned are.
- the flaps 18 are each on a transverse carriage 19 attached so that the distance between opposite one another Flaps 18 to adapt to cuboids 1 different Width is adjustable.
- a horizontal pressure plate 20 arranged by means of a scissor assembly 21 suspended on the frame 10 and by means of an actuator 22 parallel to itself is adjustable to be different Adjust the heights of the cuboid 1.
- the web 2 either runs over a deflection roller 26 on one of the Bearing blocks 24 or directly up to a first portal 27 via a second deflection roller 28 mounted there, by a also on this portal 27 frame-shaped dancers 29 through a third deflection roller mounted thereon 30.
- the dancer 29 is adjustable with the first portal 27 Actuator 31 connected, which makes it possible in the web 2nd maintain a preselected tension.
- the web 2 extends upwards again a second portal 32 and around a deflection arranged there 33, which can also be a pulley.
- a drive roller 34 is arranged, which together with a second drive roller 35 a nip forms, through which the web 2 is passed vertically downwards becomes. All pulleys and drive rollers have horizontal, 9 transverse to the direction of conveyance Axes.
- the nip is between the drive rollers 34 and 35 vertically above the gap 14 between the two conveyor lines 11 and 13.
- Transverse rail 36 is arranged, along which an adhesive application and separating device 37 can be moved.
- the work area of a driver is located 38.
- the driver 38 is a horizontal tube that transversely to the conveying direction 9, that is to say parallel to the deflection 33 and the drive rollers 34 and 35, a perforated Has lateral surface and can be evacuated intermittently, whereby the web 2 can be sucked onto the carrier 38 and can be carried by it is.
- the driver 38 forms the lower edge of a skid-like arch Web guide 39 by a in its upper third arranged hinge 40 with horizontal, with respect to the conveying direction 9 transverse joint axis A with a link 41 connected is. This is also by a joint 42 horizontal, with respect to the conveying direction 9 transverse Hinge axis B mounted on the pressure plate 20.
- the handlebar 41 is designed like a frame and has one in the middle Bearing 43 on which by an actuator 44 with a upper end region of the web guide 39, and by another Actuator 45 is connected to the pressure plate 20.
- Gap 14 Below that formed between the two conveyor lines 11 and 13 Gap 14 begins a channel 46 leading downwards, the arc-shaped forward, in the conveying direction 9, bent is, extends over the entire width of the gap 14 and gradually narrows towards the front.
- Channel 46 is on one Traverse 47 arranged, which limits the gap 14 towards the front.
- a flap 48 On the traverse 47 is a flap 48 by means of a Joint 49 mounted with a horizontal, transverse axis C.
- the flap 48 is connected to the frame 10 by an actuator 50 connected; thereby it is from a rest position in which it lies in the plane of the second conveyor section 13, in a pressing position pivotable, in which it vertically from the hinge 49 protrudes above.
- the web 2 can be dispensed with by the driver 38 and This can already be in its lower position together with web guide 39 8 have reached when the drive rollers 34 and 35th start conveying the web down.
- the web 2 from the drive rollers 34 and 35 as far down promoted that they pass through the gap 14 into the channel 46th occurs while the driver 38 back up into his Rest position is moved.
- the Slider 12 moves to the left so that it moves the cuboid 1 forward pushes. Its front 3 consequently presses against the vertically depending section of the web 2, this being itself first to the front 3 and then to the top 4 as well simultaneously applies to the underside 5 of the cuboid 1, while this is pushed over the gap 14 according to FIG.
- the lower section of the web 2 slides horizontally lying flap 48 which has a certain frictional resistance exercised on the web.
- the drive rollers 34 and 35 are during the forward movement of the cuboid 1 shown in FIG. 10 is ineffective; however, the dancer 29 acts as a brake on the web 2. As a result the web 2 is taut over the top 4 and pulled over the bottom 5.
