Definitions

  • the invention relates to a method for transferring a band around at least one object in which the at least one object is surrounded by a band, wherein the band is arranged in the form of an object band loop around the at least one object such that at least two band portions overlap and, wherein in a region in which the at least two band portions are overlapped, a reaction plate is interposed between the at least one object and the band and the at least two overlapping band portions are pressed against the reaction plate for connection.
  • the invention relates to a device for introducing a counter-pressure plate between a belt and an object, which is located on a conveying plane and a machine that uses this device and can perform the inventive method.
  • banding typically consists of paper or plastic in banding and is guided in special banding machines around the objects to be banded and joined together, e.g. by welding. If, during banding, the band is laid in the conveying direction of the objects or objects to be banded, this is called longitudinal banding.
  • Both banding and strapping are techniques for transferring ribbons around objects.
  • the term “relocating tapes around objects” is to be understood as meaning that one or more tapes are placed around and connected to one or more objects.
  • the word “Umlegen” makes no indication of the band tension, but designates only the location of the band or bands with respect to the object or objects.
  • bands When strapping the bands are often referred to as tires or straps.
  • the word "ribbon” is to be understood, unless otherwise indicated, as including bands that can be used for banding as well as straps that can be used for strapping.
  • Another holding device which is a clamp here, consisting of the rear holding device and a second clamping part, holds the upper part of the loop firmly.
  • the loop is cut open and pulled straight through the loop puller.
  • the beginning of the tape and the end of the tape are now one above the other and are welded together.
  • the counter-pressure plate generates the necessary back pressure.
  • the loop is not cut open but welded as a loop.
  • the EP 0 401 554 A1 (Büttner ) describes a longitudinal banding method. While the tape is placed around the object in a very similar process as in the aforementioned documents, the tape control differs in the mounting area. In the EP 0 401 554 A1 a gripper takes on a central role. This moves much more often and must cover longer distances than the holding devices in the aforementioned documents. The gripper has to turn around itself again and again to prevent the belt from wrapping around the gripper.
  • a counter-pressure plate is used. This plate must be movable and brought between the band and the object and removed from there. The removal is rather unproblematic, since the band is already welded at the time and together with the tension has a certain stability. A collision of tape and counter-pressure plate during insertion, however, is to be avoided. A loosely strained band may twist or fall out of the guide upon contact with the platen in this process step. A tighter band risks being damaged or destroyed.
  • the counter-pressure plate is inserted at a moment in which there is a distance between the object and the belt and that when the gripper and the rear holding device are far behind and deep below the object.
  • the band which is pulled along by the tape to be transferred, preferably to be banded and / or the object to be strapped, thus runs from the front lower edge of the object or from the front edge of an opening in the conveyor table obliquely down to the gripper or the rear holding device. This creates a space with a triangular cross-section between the band and the object. This can be used to insert the plate.
  • the counterpressure plate should come to lie completely below the band to be wrapped with the band, preferably the object to be banded and / or the object to be strapped.
  • the initial position of gripper or back fixture is given by the machine and typically, to keep the paths short, horizontal near the rear end of the platen. If the front edge of an object in the position in which the object just barely covers the counterpressure plate is only slightly above the future position of the front edge of the counterpressure plate, the clearance is very limited and, depending on the thickness of the counterpressure plate, too small. There is thus the danger that the counter-pressure plate shifts the tape during insertion or even damaged.
  • the object of the invention is therefore to provide a method of the technical field mentioned above and a device that allow a quick transfer of one or more bands to different objects with different bands and tape tensions.
  • the at least one object in a method for moving a band around at least one object, the at least one object is surrounded by a band.
  • the band is arranged in the form of an object strap loop around the at least one object in such a way that at least two strap sections are brought to overlap and connected.
  • a counter-pressure plate is inserted between the at least one object and the band.
  • the at least two overlapping band sections are pressed against the counterpressure plate for connection.
  • the method is characterized in that prior to the introduction of the counter-pressure plate, the tape is guided and / or positioned by a tape guide device, so that a defined space for introducing the counter-pressure plate is created.
  • the tape guide device By the tape guide device, the tape can be guided specifically in the area of the counter-pressure plate. This can create a defined space for introducing the counter-pressure plate. Such a space may, for example, have a rectangular cross-section. Clearances with substantially triangular cross-sections, as present in the prior art, can be avoided accordingly.
  • a defined free space holding devices and / or joining devices and / or other components of the machine can be placed closer to the position of the introduced counter pressure plate.
  • the paths of moving parts can be optimized, thereby increasing precision and / or speed.
  • a tape guiding device is used, even if the position and the geometrical shape of the object to be banded, preferably to be banded and / or strapped, are not known exactly, the band can still be accurately and safely wrapped around the tape Object to be laid. According to the invention, it suffices e.g. determine whether the tape has contact with the tape guide device and in which position the tape guide device is to decide on the timing for inserting the counter-pressure plate. Without a tape guide device, however, the exact position of the object and the shape of its front would be decisive for the course of the tape below the conveying plane and thus also for the time to insert the counter-pressure plate.
  • Tape guiding device and counter-pressure plate are part of the same machine and regardless of the objects to be wrapped from the belt, preferably the objects to be strapped and / or strapped.
  • the band is at least partially guided in the conveying direction of the object around this.
  • an object band loop around the object is formed at least partially by a movement of the object in a conveying direction.
  • the conveying direction corresponds to the direction in which the object to be transferred from the belt, preferably the object to be strapped and / or the object to be strapped, moves.
  • the object is typically moved against the belt loosely stretched in the region between the conveying plane and a belt guide above the conveying plane.
  • the tape protrudes, for example, through an opening in the conveyor plane.
  • the tape is everted during the movement of the object and lies partially around this.
  • an object strap loop is formed.
  • the surfaces of the object in the wrapping area remain open, whose (local) normal vectors point against the direction of movement.
  • the wrapping area is to describe the volume of space in which the band can move during the wrapping of the object.
  • the depth of this volume is equal to the width of the band.
  • the wrapping area lies in the space such that the object strap loop or the undisturbed stretched strap section lies completely in it.
  • the undisturbed tensioned band section forms a boundary of the wrapping area. From there it spreads in the conveying direction.
  • the top and bottom of the wrapping area are therefore at the height of the upper or lower limit of the undisturbed tensioned band section. Towards the front the wrapping area should not be limited.
  • a strip guiding device according to the invention in a loop banding method, another strapping method and / or another banding method.
  • the tape guiding device is preferably movable, in particular so that it can move in the conveying direction and / or transversely to the conveying direction.
  • the tape guide device is movable both in the conveying direction and transversely to the conveying direction.
  • the tape guide device can detect the tape targeted and move in a predefined position and / or can align. During the process steps in which the tape guiding device is not needed, it can be moved to a waiting position. As a result, space for other components is created, which allows a more compact design of the machine, preferably the banding machine and / or the strapping machine. This in turn allows shorter paths and faster work cycles.
  • the tape guide device starts at a position that is above or behind a lower grip point.
  • the lower grip point is the place where the tape is held below the object. There is no band in this place for most of the process. A risk of collision is therefore excluded.
  • the tape is moved through the object in the conveying direction.
  • the belt guiding device should also move in the conveying direction. Such a movement also achieves a clearance in which the boundaries "underside of the object" and "band" are substantially parallel to each other over a longer distance.
  • a possible starting point is inside the loop, which is the band loop into which an object is placed.
  • the movement of the tape guiding device could then, for example, run downwards or diagonally from top to bottom and from the stopping point of the loop to the edge of the counter-pressure plate farther away from this point in the horizontal direction.
  • the tape guide device can continue to move even when in contact with the tape. This allows the belt to be moved to a new position.
  • the tape guide device may travel to a location that is at the same height as the lower grip point. In the horizontal, this location is on the other side of the platen and / or the position of the platen when it is between tape and object. Thus, a trouble-free introduction of the counter-pressure plate can be made possible.
  • tape and tape guiding device Another way to bring tape and tape guiding device in contact, for example, is that the tape is selectively brought into contact with the tape guide device while the tape guide device does not move or stand still. This could e.g. are made by a hook, by an air pressure pulse, by changing the belt tension, by changing the position of the point where a part of the belt is held, etc. It is also possible that both the belt and the belt guiding device are moved to establish contact.
  • the tape guiding device is a tape guiding hook.
  • Such a hook preferably has a shape that resembles a L.
  • the tape guide device is advantageously an L-shaped tape guide hook.
  • the short leg is preferably at least as long as the band is wide. Over the long leg, typically at the end, the hook is guided. This guidance is done by a suitable mechanism, for example by means of suitable cams, guide elements and a motor or by, for example, a hydraulic or pneumatic control, by means of electromagnets or cables or other methods for carrying out a controlled movement.
  • the length of the legs is reversed or the legs are the same length.
  • the choice of length depends on the width of the belt, the drive and the construction of the machine.
  • the legs do not have to be at right angles to each other. This can also serve to make the structure of the machine more flexible and also a lateral slipping of the band can be difficult.
  • the end of the thigh contacting the band may be rounded or specially smoothed.
  • the latter can either be done directly by the material processing or by a coating.
  • Such a coating may be comparatively thick or very thin. Such treatment can reduce the risk that the band will be damaged by contact with the hook.
  • the hook may be wholly or partially coated to either allow the tape to slide better and / or to prevent it from slipping sideways.
  • the hook may be grounded to prevent electrostatic charging of the belt and hook.
  • one leg serves to attach the hook at the desired location.
  • the hook can be used both in the Leksssbanderolierbacter or Lekssumreifungsbacter and in another banding and / or Umreifungsbacter such as a loop method as a tape guide device.
  • the tape guiding device can also be another component of the machine, which is arranged at the desired position and around which the tape can be laid.
  • a cohesive and / or positive connection is established when connecting the overlapping band sections, in particular with the aid of a joining device.
  • Typical cohesive bonding methods are, for example, welding, gluing and / or fusing.
  • a positive connection between two strips can be achieved, inter alia, by suitable stamping, punching and / or folding or, for example, knotting.
  • suitable stamping, punching and / or folding or, for example, knotting In the welding process, in particular ultrasonic welding is preferred.
  • the joining device performs the desired connection method, wherein the counter-pressure plate can hold the necessary back pressure.
  • a joining device may, for example, be a welding head, in particular an ultrasonic welding head. However, it may also be Schulamellen, which are pushed between the bands and a stamp that presses the heated bands against the counter-pressure plate. For example, adhesive can be applied by the joining device. The bands can then be pressed against the counter-pressure plate, for example, with a punch for joining.
  • the joining device may also include an embossing tool, for example a punching tool.
  • the joining device can, for example, fold or knot.
  • the joining device is chosen so that it can perform the desired method, in particular by using the counter-pressure plate.
  • the counter-pressure plate is planar in an advantageous embodiment. This is not mandatory.
  • the configuration of the counter-pressure plate is adapted to the respective connection method.
  • connection method can basically be chosen independently of the selected banding or strapping method. It can also be chosen independently of the specific embodiment of the tape guide device. Therefore, in principle, all combinations are possible.
  • a cohesive connection is produced, in particular by a welding process, preferably by an ultrasonic welding process
  • the bands used in banderoller machines and / or strapping machines are made of plastic or coated paper. Welding processes result in stable bonds and do not require movement of the bands. Therefore, they can be well integrated into the machine, such as a banding and / or strapping machine. Welding based on heat often requires special tapes or coatings. Ultrasonic welding allows a wider choice of materials. It also has the advantage that hardly any heat, exhaust gases or dust arise.
  • Bonded joints often take longer to fully load. On the other hand, the appearance of the bands is hardly affected.
  • Positive connections have the advantage that they can often be produced almost purely mechanically and quickly (for example embossing and punching).
  • connection method is advantageously matched to the material of the band.
  • a belt tension is controlled by a belt tensioner during the entire process.
  • the strap tensioner is in particular a device through which the strap passes.
  • it is located between a tape source, such as a supply reel and the conveying plane.
  • the tape tensioner is disposed between the tape source and an area at which the tape, coming from the tape source, for the first time has the opportunity to come in contact with the object.
  • the belt tensioner can perform the task of controlling the belt tension in various ways:
  • the belt tensioner comprises at least two elements between which the belt passes and wherein at least one of the elements is displaceable relative to the other element.
  • a first element may be, for example, a jaw, a roller or a pin.
  • the first element is characterized in particular by the fact that the tape can be pressed non-destructively and that it can be moved relative to the second element, which can be shaped quite differently than the first element, such that a moving between the two elements band is slowed down in his movement.
  • at least one of the elements is a roller which rotates at a certain speed or in which the rotational speed can not exceed or fall short of certain minimum and / or maximum values.
  • a special motor can be used to generate the desired speed and / or its control.
  • Another possibility is that the movement of another engine of the machine shared and appropriately deflected and implemented.
  • a rotating roller may be a jaw or a pin or other element, which can move in the band extension direction. The pressure between the two elements can be so high in this embodiment that the static friction of the band on the at least one roller is greater than the sliding friction.
  • the tape is therefore transported in a controlled manner via the rotation of the roll or a tape movement is controlled by the roll.
  • the pressure between the elements may be generated, for example, by a spring, by magnetic forces, by a pneumatic or hydraulic device, by the weight of one of the elements, or by other types of power transmission. It is also possible in principle that a distance between the two elements is fixed.
  • the adhesive and / or sliding friction properties between the elements or the contact surfaces of the elements and the tape can be suitably influenced by coatings or surface structuring.
  • the belt tension is changed during the process.
  • the tape tension is set lower during a first contact of the tape with the object than during the period in which the at least two tape portions are made to overlap.
  • a banding method and / or a strapping method in particular if the object is sensitive, it may be advantageous that the band is only slightly tensioned at the time of initial contact with the object. This results in only small forces on the contact points of the object. In many cases, however, a higher belt tension is desired for the actual transfer process (preferably banding or strapping), e.g. to securely and firmly enclose the object.
  • a belt tension which can be changed during the process, both requirements can be met: The belt tension can be low at the time of initial contact and can be increased before connecting the belt.
  • the contact surface between the object and the belt may already be considerably larger than at the time of initial contact, so that the object is not damaged by the higher belt tension at a later time.
  • a similar change in tape tension can also prevent an object moving from a stack of things projecting differently in the direction of conveyance from shifting or shifting smaller than would be the case without changing the tape tension.
  • the band tension is initially large and then reduced. For example, an edge or side of the object may be intentionally violated, for example to prevent a comparatively loose band from slipping off the object.
  • the belt tension can be changed by various mechanisms: In a belt tensioner which uses sliding friction, ie in which the belt passes between two elements essentially resting with respect to the belt, the belt tension is changed by a change in pressure between the belt tensioners controlled by both elements. But it could also be the surface properties of Band and / or one and / or both elements. This is done, for example, by applying a lubricant or inserting intermediate layers.
  • the belt tension may preferably be made by changing the moving speed of the moving parts. If a motor is used to drive and / or control, for example, its speed can be adjusted.
  • a belt tensioner which uses the static friction, the pressure between the elements and / or their surface texture and / or the surface of the belt changes so that there is also a sliding of the belt between the elements.
  • the belt tension is controlled by a control unit, in particular by electrical signals.
  • the control of the belt tension via a control unit has the advantage of user-friendliness and safety.
  • the user should not for safety reasons directly on a component of a machine that is not explicitly intended to handle it.
  • the belt tensioner is mounted and / or executed so that it is also directly and without control at any time adjustable so that the belt tension is changed.
  • Electrical signals have the advantage that they can be generated and transmitted well and one has a relatively large freedom in the choice of the transmission path. This is less straightforward, for example, with cables which would also enable signal transmission. Wireless signal transmission using electromagnetic waves requires special receivers on the belt tensioner. By contrast, with the aid of a suitable electrical signal, it is possible to use a motor or a brake which influences or controls the movement of an element or the pressure between the elements. direct control. Even a pump, valves and other controls of a pneumatic or hydraulic mechanism can be electrically influenced. The pressure change between the elements can be adjusted directly by means of suitable cables in many pressure generating methods. An advantage of electrical signals, however, is that they can be relatively easily and in the usual form today form of programmable control units or change.
  • Suitable sensors may be incorporated directly into the belt tensioner and for example measure how much one or more of the elements are pulled from the belt in the belt direction or what the torque of the belt is on e.g. is a role. Together with the known sliding and / or static friction properties between the measured element and the belt, a force and thus the belt tension can be determined therefrom.
  • One or more comparable sensors could also be attached (additionally or alternatively) to the lower attachment point.
  • the torque caused by the belt tension may show itself in current and / or voltage signals.
  • the belt tension can be measured.

  • the rear holding device here represents the lower holding point.
  • the rear holding device defines, inter alia, the position of the lower end of the free-tensioned belt before it comes to be transferred from the band, preferably to be banded and / or the object to be strapped into contact.
  • the tape guide At the tape guide, at the position in a plane above the object, is the position of the upper end of the free-tensioned tape.
  • the rear retainer holds the strap locally so that the retained part can not slip through or over the retainer.
  • the tape guide is preferably designed to control the course of the tape but not to fix the tape locally.
  • the tape can and should therefore move in or around the tape guide in this embodiment, for example, when the tape is tensioned with some force by the movement of the object or by the movement of the tape guide or by a movement of the machine.
  • Tape guide and tape tensioner can be a component with which the course of the tape and the tape tension can be controlled in the same place.
  • it may simply be a pin, a roller, a surface which may be curved.
  • the tape is placed and either it can slide over it or it is movably supported by the rotation of the roller or the movement of pin or surface.
  • a pin, surface or roller may be surrounded by devices which prevent the belt from slipping off, such as side bars in the form of short bars or surfaces. It is advantageous if the friction between tape and tape guide is kept small if the tape tensioner is not part of the tape guide. In this case, otherwise the tape tension produced by the tape guide would have to be taken into account in the tension regulation of the tape, which makes setting the tape tension somewhat more difficult. In addition, the smallest possible belt tension is increased by the friction between belt and belt guide.
  • the rear holder is typically a clamp. So it consists of two jaws that can be pressed together.
  • the band to be held can be clamped in between.
  • the jaws are so selected and the pressure determined so that the tape can not be pulled between the jaws even with the highest, occurring in the process tape tension.
  • the band is not damaged by the pinching. Since it is the beginning of the tape and this is in the finished product near the junction, damage to the tape would be less noticeable at the site than elsewhere. It is therefore conceivable that the tape is held by the rear holder also with a method which damages the tape. For example, it could be one or more needles that are stung by the tape.
  • the term "move through the tape guide” is also intended to include the sliding of a tape over a dedicated surface of a tape guide.
  • the object can not be completely enclosed by the band because there are always places in physical objects whose local normal vector at least partially against the direction of movement of the object and these locations also occur in each Umwicklungs with these points. At these points can be brought by the movement of the object and the evasion of the tape alone no band. This is achieved with the help of the tape guide, which presses the tape behind the object below the conveying plane. The necessary mobility she gets preferred by a movable arm on which it is stored.
  • the tape guide may also include suitable rails and a mating carriage on the tape guide, or the tape guide could be attached to a type of pole that can be raised or lowered.
  • the tape To close the last piece of object tape loop, the tape must be brought from the lowered tape guide under the object where the rear holder is with the beginning of the tape. This is done with the help of the loop puller.
  • the loop puller is an L-shaped hook or pin.
  • the pin or hook is placed at this point of engagement between the tape guide and the tape.
  • the tape guide is designed so that the tape is held above and below the point of engagement in the vicinity of the tape guide. This can for example be done via two suitable pins or a housing in which is only an opening to the point of engagement.
  • the tape can also be held, for example, with negative pressure in or on the tape guide.
  • the loop puller is now at least partially brought into the point of engagement and thus between tape and tape guide.
  • the loop puller comprises a device which sucks the band under negative pressure.
  • the loop puller If the loop puller is now moved in the conveying direction, it moves the strip with it and thus creates a loop that starts and ends in the tape guide.
  • the tape tension is controlled to take a first value while no object touches the tape, a second value while the tape is being moved by the object, and a third value as the tape guide pushes or moves the tape down.
  • the second value of the belt tension is not greater than the third one.
  • first, second and third values are not constant in time but continuously merge into one another.
  • the first value is the stress that the front edge of the object can withstand or with which the front edge is to be processed.
  • the second value should be chosen among other things with reference to the transport mechanism of the objects. Too high a belt tension would slow down the object, stop it or even push it back in the opposite direction to the transport direction. When lowering the tape guide, however, the object is already majority surrounded by the band. The forces are distributed more evenly over the surfaces touched by the belt, and since a certain length of belt is needed, a belt tension can be built up without the need of a mechanism which retracts the belt. Due to the fact that the band already surrounds the object by a majority, there is less risk that the object or parts thereof will be moved unintentionally at this time.

However, the speed should be known essentially at any time during the measurement for a meaningful evaluation.
