Definitions

  • the invention relates to a method for applying flat strapping bands made of a plastic or metal material to packages by means of a strapping device according to the features of patent claims 1 and 7 and strapping devices for carrying out the method according to patent claims 14 and 20.
  • Strapping devices for strapping objects count in different versions of the prior art.
  • the basic principle of strapping is based on positioning a strapping head on a package to be strapped, feeding a strapping band around the package, tensioning the strapping band, and joining its ends within the closure head.
  • the overlapping ends of the prestressed strapping band become cohesively or positively with each other connected.
  • the removed from a supply roll strapping is separated and the closure head lifted from the package.
  • Strapping is subject to extreme loads, in particular dynamic loads which occur during the transport of the packages can become so great that the strapping tapes break.
  • rod or tube-like metal products are bundled by strapping. When such bundles are transported by means of a crane, deflection forces occur forcibly outside the points of application of the stop means, which in turn leads to displacement of the bars or tubes with one another.
  • the strapping bands must absorb the resulting loads. Theoretically, it is possible to provide a larger number of strapping bands to prevent such displacements.
  • tube bundles and other rod-like products are so-called rigid packages that have a very limited flexibility.
  • the invention is based on the object, a method and an apparatus for bypassing or flipping flat strapping of a plastic or metal material, in particular steel, to show packages that very much because of their high weight, their volume or their critical shape put high demands on the transport protection created by strapping.
  • the device according to the invention is based on the basic idea of double or multiple strapping, wherein the beginning of the band of the strapping belt used is guided not only once but several times around the package before being connected to the band end.
  • Another aspect is that it is hardly possible in practice to strap packages in such a way that both strapping belts are pretensioned with exactly the same tensile force. The reason is that when creating a first Einzelumreifung the package is compressed and biased. This first strap loop absorbs the entire bias. Although a second belt loop in the form of a single strapping lying directly next to the first belt loop can likewise be pretensioned with a preset tensile force, this results in a, albeit slight, relief of the first belt loop. This is not a uniform burden The strapping more given, with the result that in a Zerr devisprobe one of the strapping earlier failed than the other.
  • a decisive influence on the load bearing capacity has the higher elasticity of the multiple strapping due to the greater strip length and the resulting ability to absorb shock loads better.
  • the elasticity of a multiple strapping increases linearly with the number of strapping.
  • a significant advantage of the invention is that, for the application of multiple strapping, standard strapping bands of metal, i. usually made of steel, or plastic can be used. Although twice the length of strapping must be used for a double strapping, only one closure is necessary, so that with a single closure head a double or multiple strapping can be applied faster than several individual strapping.
  • a strapping device in the context of the invention may be a stationarily installed, stationary strapping device, to which the packages are fed, or may be designed as a movably designed device, which moves over a Stabbund. In both cases, the strapping or sealing head is displaceable within predetermined limits relative to the package.
  • the methods described below are carried out with the aid of stationary or quasi-stationary strapping devices.
  • the automation of the strapping process in a stationary or quasi-stationary strapping device is technically relatively complicated, since the strapping crosses once in a double strapping.
  • the method according to claim 1 is as follows:
  • the package to be strapped is brought into a strapping position of the strapping device and a closure head is brought into a starting position.
  • the closure head feeds the strap, which it removes from a supply roll, to a gripping unit. Between the supply roll and the closure head suitable supply means are provided.
  • the gripping unit clamps the beginning of the tape and guides it several times, in particular twice around the package to be strapped. At the same time strapping is tracked by the closure head. After at least two tape loops were applied, the beginning of the tape is fed back to the closure head and held there. In the closure head, the strapping is tensioned by pulling back into the closure head to a preset tensile force. In known In this way, the beginning of the strip inside the closure head is connected to the end of the withdrawn strapping band. The end of the strapping band connected to the supply roll is severed. Subsequently, the closure head is removed from the package again, so that the package can either be removed from the strapping device or positioned so that a further strapping of the package can take place.
  • the inventive method it is possible with the inventive method to perform strapping with more than two belt loops. Preferably, however, they are double strapping, i. Strapping with two strap loops.
  • the gripping unit is arranged on a guide ring surrounding the package, wherein the guide ring is rotated with the gripping unit to the gripping unit with the clamped beginning of the tape to move around the package.
  • the guide ring is fixedly mounted and the gripping unit is moved to the fixed guide ring. In this case, however, the gripping unit would have to be provided with a corresponding drive and a power supply. It is considered easier to turn the guide ring completely, since in this case a power supply to the gripping unit can be omitted.
  • a piston-cylinder unit in particular a pneumatic or hydraulic cylinder can be provided for this purpose, which actuates the mechanically acting clamping unit.
  • the clamping force is preferably from a Spring force applied, which presses a jaw against the strapping.
  • the gripping unit does not collide with the closure head when driving around the package. Therefore, it is necessary to shift the closure head out of the movement path of the gripping unit. This can be done either by the fact that the closure head is moved or the guide ring is displaced when the gripping unit passes through the closure head. If, however, the gripping unit has to transfer the beginning of the strip to the closure head again, the closure head is to be displaced into the movement path of the gripping unit so that the beginning of the strip can be introduced into the band inlet side of the closure head.
  • a transport device is arranged between the band inlet side of the closure head and the gripping unit, which transports the strapping band into the closure head after releasing the clamping of the gripping unit.
  • This transport device is in a preferred embodiment, a transport roller which presses on a flat side of the belt of the strapping and as well as the closure head in the movement path of the gripping unit is displaced or out of the movement path is displaced when the gripping unit in the application of the first strapping the position the transport device happens.
  • suitable guideways may be provided to bring the beginning of the tape in the closure head accurately.
  • the strip beginning of the strapping band is to be held in the gripping unit by clamping. This can be done by pressure on its flat sides as well as by clamping the long sides.
  • the clamping over the longitudinal edges has the advantage that the strapping can be easily pulled out of the gripper unit when loosening the clamp, which is not readily possible with a clamping on the flat sides.
  • the clamping over the longitudinal edges requires that the strapping band not twisted or slip off of the jaws provided in the gripping unit.
  • the strapping should be performed arcuate within the gripping unit, so that this arcuate portion is clamped.
  • the strapping band can not buckle.
  • Of the side of the band end arranged jaws needs only a jaw to be arranged to be movable.
  • the movable jaw opposite jaw serves only as an abutment.
  • the abutment can be referred to as a jaw.
  • the technical problem to be solved in this context is the design of the tape guide channels, which inevitably have to have a crossing point on a side opposite the closure head side.
  • a first band guide channel is provided which surrounds the package and a second band guide channel, which connects to the first channel and also surrounds the package.
  • additional tape guide channels can be provided to make not only double but triple or quad strapping.
  • the technical complexity of triple or quad strapping is very high, since there must be opportunities at the intersection of each band guide channels to open the respective inner band guide channels when the closure head spans the strapping.
  • the core of the method according to claim 7, therefore, is that the closure head opposite intersection of the band guide channels is released.
  • the inner, closer to the package strip guide channel is executed divided, wherein at least one of its sections is moved out of the crossing point.
  • the crossing point is released, the strapping band can be pulled into the closure head and thus tensioned.
  • spring-loaded holding means are provided for the strapping, which open automatically overcoming the spring force and release the strapping, so that it can get to the package to the plant.
  • both tape guide channels so that they are opened at the intersection, for example, if rod-shaped packages are to be introduced in a sense not in the axial direction of the openings formed by the tape guide channels, but in the radial direction, so to speak, transversely to the tape guide channels in the strapping.
  • rod-shaped packages are to be introduced in a sense not in the axial direction of the openings formed by the tape guide channels, but in the radial direction, so to speak, transversely to the tape guide channels in the strapping.
  • an inner and at least one further, outer band guide channel is provided
  • the alternative according to claim 9 is to rigidly form the band guide channels and to connect them at the point of intersection.
  • an intersection is provided.
  • the essence, however, is that not all the band channel has to be moved out of the intersection, but only one slider separating the inner band channel from the outer band channel has to be opened to receive both the inner band and the outer band from the respective band channels and pull out the tape guide channels.
  • Such a slider has the advantage that it is a much smaller moving component, as in a whole band guide channel. Therefore even smaller drive units are required.
  • the construction is more compact.
  • the slider has two functions during the running in of the band: on the one hand, it is the wall of the outer band channel but at the same time also the boundary of the inner band channel.
  • the slider is even configured in a U-shape such that it forms three walls of the inner band channel within the crossing region like a fork.
  • the strapping enters after entering the first band guide channel in the second band guide channel, via a bypass channel which extends along the closure head.
  • the bypass channel is connected to the end of the first tape guide channel and the beginning of the second tape guide channel.
  • This bypass channel is preferably positioned as close as possible to the tape inlet and outlet channel of the closure head, so that the distance of the belt loops is minimized. In this way it is ensured that the strapping does not loosen by lateral displacement of one or both of the strap loops, with the result that the bias of the strapping decreases.
  • bypass channel is opened after the application of the belt loops and the belt loop is displaced from the bypass channel in the direction of the tape inlet and outlet channel of the closure head. This measure can be done with a reduced band loop before tightening the strapping. Regardless of this, it is considered expedient if the displaced belt loop is prevented from displacing out of this position into the bypass channel after being displaced into the region of the belt inlet and outlet channel by at least one blocking element.
  • the blocking element is preferably a pawl which is mechanically coupled to a pusher element which is used to displace the second band loop into the band inlet and outlet channel.
  • the strapping device according to claim 14 is intended to carry out the method according to claim 1. It is an automated device in which the complete strapping process is controlled by a control unit.
  • the strapping device is for this purpose provided with corresponding actuators and sensors which are connected to the control unit.
  • the strapping device comprises in this embodiment, a gripping unit, which has means to grab a pushed out of the closure head strip beginning and perform several times around the package and finally feed the tape back to the closure head.
  • the gripping unit is arranged on a displaceable in a rotational movement about the package guide ring.
  • the closure head can be displaced out of the movement path of the gripping unit in order not to come into contact with the gripping unit after the application of the first belt loop. A displacement of the gripping unit is also possible.
  • the gripping unit is located in front of the band inlet side of the closure head.
  • a transport device can be introduced between the closure head and the gripping unit in order to transport the beginning of the strip into the band inlet side of the closure head.
  • the tape end is not guided by a gripping unit, but by tape guide channels, which surround the package to be strapped twice.
  • tape guide channels which surround the package to be strapped twice.
  • the inner band guide channel adjacent to the package is divided in a first embodiment so that at least one of its sections can be moved out of the crossing region, in particular swung out.
  • moving out or swinging out of the sections of the packaging tape is freed from surrounding parts and can be pulled out of the band guide channel until it rests on the package.

  • the strapping device 1 comprises a frame 2 with a movable in height boom 3, on which a closure head 4 is arranged.
  • the closure head 4 serves a in FIG. 8 illustrated strapping 17 output, which is a package. 5 to be led around.
  • the package 5 is configured hexagonal in cross-section. For example, it is a bundle of rods or tubes. The smaller of the two hexagons shown should make it clear that the package 5 can have different sizes.
  • the closure head 4 is located above the package 5. It is positioned so that the closure attached by the closure head 4 is always located centrally on the top of the package 5. For this purpose, the closure head 4 can be displaced in not horizontally positioned packages 5 in a manner not shown in the horizontal direction.
  • the strapping device 1 further comprises a guide ring 6 which surrounds the package 5 and is rotatably mounted about its longitudinal axis L. With the guide ring 6, a gripping unit 7 is fixedly connected. When the guide ring 6 is set in a rotational movement, the gripping unit 7 also rotates about the longitudinal axis L and thus around the package 5.
  • the gripping unit 7 is intended to grab a issued by the closure head 4 strapping 17 at its beginning of the tape 31 and to fix it by clamping.
  • the gripping unit 7 is provided with a jaw 8.
  • the jaw 8 would act on the wider flat sides of the strap 17.

In the present case, a double strapping is to be created. Therefore, two tape guide channels 13, 14 are provided. In a double strapping, as in FIG. 8 is shown, there is inevitably a crossing point K, in which the belt loops 15, 16 of the strapping 17 intersect. When using tape guide channels 13, 14, it is unavoidable during the application of the belt loops 15, 16 that one of the belt guide channels 13, 14 is closer to the package 5, than the other.
