Description

The invention relates to a binding device and a method for binding slit strip rings.

Slitband rings are coils of flat rolled metal coils. It is known to tie slit band rings with a binding band to ensure for transport and handling that the rings are firmly held together and neither roll nor fall apart in the axial direction.

However, slit strip rings are difficult to handle, on the one hand by the high weight and on the other hand, that a mechanical detection of the rings is made difficult by the tendency to unroll or axial falling apart. In the warehouse or after production, slit band rings are usually vertical and must be transported by means of a crane and brought to a binding station, where they are preferably bound in several places with tape, before they are stored for transport, for example. On a pallet in a horizontal orientation. So far, the corresponding workflow, in which each ring must be attached to the crane, at a binding station, eg. A binding table, filed, bound, then attached again and finally must be stored relatively expensive.

It is an object of the invention to propose an apparatus and a method to facilitate the bonding of the split band rings.

This object is achieved by a binding device according to claim 1 and a method according to claim 15. Dependent claims relate to advantageous embodiment of the invention.

The binding device according to the invention, which also in the inventive method is used, comprises a handling device for transporting and holding a slit band ring and a binding station. Usually, the binding station has at least one binding head, preferably a plurality of binding heads, of which in each case a band is fed for binding the split band ring.

In this case, the handling device on a load-receiving unit for attachment to the slit strip ring. The load-bearing unit is rotatably mounted on a support frame about a rotation axis. It has for fastening and fixing the Spaltbandrings on the one hand on a spreader unit and on the other hand, a (further) holding device.

By means of the spreading a Spaltbandring, which usually has an outer and an inner diameter, held from the inside with pressure to the outside to prevent unrolling of the Spaltbandringes. For spreading, preferably spreading means, for example at least two spreading arms are arranged on the spreading unit, which are adjustable via a mechanism in order to apply compressive forces to the inner surfaces in opposite directions. For driving the spreader unit, depending on the spreading means, for example, motors, pneumatically or hydraulically operated piston-cylinder systems or even screws / spindle drives can be used.

The (further) holding device serves to hold a slit band ring on the load-receiving unit in such a way that it can be handled there and, for example, also rotated with the load-carrying unit. It can also be carried out, for example, mechanically and, for example, comprise gripping arms or a clamping device which produces a positive-locking and / or frictional connection, for example, with the split-band ring. Also, pneumatic holding devices are possible, which generate a negative pressure and suck the slit strip ring. Therefore, all types of holding devices can be used which produce a secure but releasable hold between the load-receiving unit and the split-band ring. Advantageously, a holding device with magnets, preferably switchable permanent magnet.

By means of the handling device, which is preferably attached to a crane, so the slit strip ring can be moved, positioned and transported. In particular, the split-band ring can be transported to the binding station in order to bind with a band become.

In this case, the load-receiving unit comprises a recess, preferably a channel for passing the band, so that the band can then be placed around the split band ring as long as it is held on the load-bearing unit. In this case, a recess is understood to mean an opening that points in the cross-section, through which a band can be guided.

Advantages of such a binding device formed from handling device and binding station is that for the binding no separate picking and dropping the Spaltbandringes is required, but the Spaltbandring be taken once during handling and fixed attached to the handling device before he further handling, eg. Tray on a pallet, is fed. So on the one hand good handling is given and on the other hand ensures efficient processing.

In order to achieve a favorable guidance of the band, deflecting units are provided according to preferred embodiments, d. H. Elements whose shape causes a deflection of an advanced belt around a deflection angle. On the one hand, at least one station-side, d. H. provided at the binding station deflection unit, with which a belt fed from the binding head is guided in the direction of the recess on the load-receiving unit, or coming back from the load-receiving unit band again in the direction of the binding station. The deflection can be done by a deflection angle of, for example. 30 - 150 degrees, preferably by about 90 degrees. It is particularly preferred if the station-side deflection unit is arranged to be movable, in particular movably between a basic position and a binding position. In the binding position, the deflection takes place in the direction of the recess. In the basic position, the deflection unit is preferably arranged sunk, so that it does not interfere with a movement of the handling device or the Spaltbandringes. The adjustment between the positions is preferably carried out by an actuator, such as, for example, a motor or piston drive.

Also preferred is a device-side, ie provided on the handling device deflecting unit on the load-receiving unit. In this case, a station-side deflection unit and cooperate with a device-side deflection unit, wherein they are preferably positioned next to one another in a binding position. Such pairs of deflection units are preferably provided at both ends of the recess.

According to a preferred embodiment of the invention, a cover for the recess is provided on the load-receiving unit. The recess itself may be formed as a depression, but also be shaped only by the cover to a channel. The recess is preferably covered by at least one end member so that the tape can be inserted through the recess in the longitudinal direction and does not come out of the recess. The closure element, which can be provided, for example, as a closure plate, is preferably movable, so that the strip can be pulled out of the recess in the transverse direction when tightened. Particularly preferably, a closure element can be arranged resiliently pivotable, so that it automatically releases this when tightening the band. The recess is preferably provided as a longitudinal channel in at least one arm of the load-receiving unit. More preferably, a plurality of arms of the load-receiving unit, each forming an angle to each other, provided with longitudinal channels as a recess for the binding. More preferably, there are four channels, which are arranged in approximately 90 degrees to each other. While it would be possible in principle to provide a binding station with a smaller number of binding heads, preferably the number of binding heads also corresponds to the number of recesses, that is to say particularly preferably four, so that the corresponding number of bindings can take place simultaneously.

Further advantageous embodiments relating to the binding station. This preferably has at least one binding head, more preferably with one or more of the following elements: a belt feed for feeding the belt, a belt tightening unit for tightening the closed belt loop, a connection unit, preferably a friction welding unit for welding the belt and fastening the belt loop and a separation unit for Separating the tape. Particularly preferably, the binding head is arranged displaceably. Thus, it can be moved with different positioning of the slit strip ring and in particular for the binding of slit strip rings of different diameters. It is particularly preferred that the binding head is arranged horizontally freely displaceable, so it is not motorized by a separate drive but - force-free or possibly against the force of a centering return unit, eg. Suspension - can be moved by external forces within these limits. With such an arrangement, it is possible that the belt loop is first placed loosely around the area in which the split band ring is arranged. During the subsequent tightening of the belt, the belt loop then centers on the split belt ring, whereby the binding head shifts automatically.

According to a preferred embodiment, a centering device is provided to facilitate the positioning of the handling device relative to the binding station. Preferably, the centering device comprises interlocking elements, more preferably at least two pairs arranged at opposite ends thereof. It is further preferred that the station-side arranged elements are arranged to be retractable, particularly preferably by means of a drive displaceable.

Further preferred developments relating to the handling device.

It can be arranged on the handling device, a distance sensor which is designed to determine at least one point the distance of the load-bearing unit to the split band ring. As a result, a close contact between the split band ring and the load-bearing unit can be achieved. The attachment of the load-bearing unit on the split-band ring is an important step in the transport of split-strip rings. Through the attachment must be ensured that the slit strip ring is securely and firmly attached to both the transport and the rotational movement of the load-bearing unit. Too fast starting of the handling device on the slit strip ring or uneven application of the load-receiving unit on the split strip ring, it comes to irregularities in the fastening process. To make matters worse, that the operator is often behind the handling device and thus can not fully grasp the slit strip ring and in particular the distance between the load receiving unit and slit strip ring.

The inventive arrangement of a distance sensor, it is possible for the operator, even without visual contact, the distance of the load-receiving unit for Spaltbandring capture. This makes it possible that the attachment of the load-bearing unit takes place evenly and exactly aligned on the split band ring. Due to the correct fastening of the slit strip ring to the load-receiving unit, unintentional loosening of the slit strip ring during transport or even during the rotational movement is also prevented.

Another advantage is that the distance sensor makes it possible to equip the handling device with additional security and monitoring functions. Thus, for example, the spreading of the spreader unit can be prevented as long as the distance sensor measures too large a distance. In the same form, it is also possible, for example, to configure the functions of the holding device as a function of the distance sensor.

As a distance sensor, all known from the prior art types of sensors for measuring distances can be used, for example. An optical or mechanical sensor. Since the material of the slit band rings is ferromagnetic, a magnetic sensor or inductive sensor is particularly suitable.

For fixing and attaching the slit band ring to the load-bearing unit, the distance between the load-bearing unit and slit band ring is crucial. In order to ensure a safe transport of the slit strip ring, the distance should be particularly low and, in particular, largely uniform over the entire slit strip ring surface.

According to a particularly advantageous embodiment of the invention, two spaced-apart distance sensors for measuring the distance between the load-receiving unit and the split-band ring are arranged at different measuring points.

Due to the two spaced apart distance sensors, it is possible in a particularly simple manner to determine a skewed gap band ring or a not exactly vertically oriented load-bearing unit by different distances.

More preferably, an actuator is provided to rotate the load-bearing unit relative to the support frame. An actuator is understood to mean a force unit which is driven by a force medium and, in turn, can be used as a drive, for example. Force units can be, for example, electric motors, spindle / worm drives or piston-cylinder systems. Force medium can be, for example, the electric current for an electric motor or compressed air / oil for a piston-cylinder system. In particular, an actuator is preferred which generates a linear movement. The force that the operator has to spend on the rotational movement is reduced or completely taken over by the actuator.

The actuator can, for example, transmit its force directly to the axis of rotation or also act, for example, by means of a gear on the rotational movement of the load-receiving unit. Also, for example, spindle and / or screws are suitable for power transmission. According to a particularly preferred development of the actuator is designed as a linear drive unit, particularly preferably as a piston-cylinder unit, which changes by at least one lever arm, the position of the load-bearing unit relative to the support frame.

According to a development of the invention, the axis of rotation of the load-bearing unit is arranged outside a center of gravity axis of the load-bearing unit. In an arrangement of the axis of rotation in the center axis of the load-receiving unit acts in the unloaded state no tilting moment on the load-bearing unit, so that this is largely balanced. By receiving the slit strip ring but there is a shift in the center of gravity of the overall system (load-bearing unit and slit strip ring). This results in a tilting moment, so that the load-bearing unit tilts automatically in the direction of the larger weight in this case, the slit strip ring.

The preferred arrangement of the axis of rotation outside the center of gravity axis of the load-bearing unit, it is possible to reduce the occurrence of a tilting moment on the load-bearing unit in the loaded state by the axis of rotation is arranged closer to the axis of gravity of the overall system. Therefore, it is preferable that the load receiving unit has a receiving side and a rear side, and the rotational axis of the load receiving unit is shifted from the gravity axis toward the receiving side. The orientation of the axis of rotation can be at any suitable position in the range between the axis of gravity and the receiving side. For example, the axis of rotation can be arranged centrally between the receiving side and the center of gravity axis. Also, for example, positions between a quarter of the distance between the receiving side and axis of gravity and three quarters of the route are possible.

In a further preferred embodiment, the handling device on a suspension, for example. Hook or eye on the support frame, which is to be attached to a crane.

In this case, a pull sensor may preferably be provided for measuring the load on the suspension. The tension sensor is advantageously fastened between the suspension and the crane and can, for example, be designed as a tensile load cell. This is loaded by the load of the handling device. When receiving the Spaltbandringes by the handling device an additional load of the train sensor takes place. The train sensor may, for example, be equipped with a display so that the operator can determine the load hanging on the crane at any time. However, the traction sensor is particularly preferably designed such that it transmits the data determined by it to a control unit. This can lock, for example, in case of overload functions such as lifting the handling device.

According to a particularly advantageous embodiment of the invention, a control unit is arranged on the handling device, which is designed to receive data from at least one distance sensor and / or a train sensor and / or an operating unit and process data. Further, the control unit is adapted to control the spreader unit for fixing the slit strip ring and / or to control an actuator for rotating the load receiving unit and / or to control a crane to which the handling device is attached to move and / or to control the holding device for fastening the slit strip ring ,

The control unit thus serves to receive and process data and to drive a plurality of functional units. The control unit may, for example, pneumatically, hydraulically or mechanically act. Thus, a pneumatically / hydraulically acting control unit, for example, via the actuation of valves different functional units, such as driving a piston-cylinder unit.

Although the processing of data within the arithmetic unit of the control unit can in principle likewise be constructed as a mechanical system, an electronic arithmetic unit is preferred for this purpose. The arithmetic unit can be designed both analog and digital, preferred is a program control by means of a microcontroller or microcomputer and more preferably the arithmetic unit is a PLC (memory programmable controller).

Particularly preferred is an embodiment of the control unit, which is designed to control the crane based on the received data of the train sensor so that the crane aligns the load receiving unit to the slit band ring in the vertical direction in the middle when receiving the slit band ring.

If the load-bearing unit is oriented too low, the spreader unit in the split ring sets prior to fixing, as a result of which the load-bearing unit is supported on the split-band ring and the strain sensor is relieved. The control unit detects the reduction of the load and controls the crane so that the receiving unit is pulled in the vertical direction upwards.

If the load-bearing unit is set too high on the split-band ring, the upper part of the spreader unit first engages in the split-band ring and tries to lift the split-band ring before complete fixing. As a result, the train sensor is additionally loaded. The control unit is designed to determine this additional load and to lower the load-bearing unit in the vertical direction by controlling the crane. It is also possible, for example, to use a control unit which is programmable and / or is to be set such that a position adaptation of the load-bearing unit takes place only when a certain load is exceeded / undershot. A value suitable for such a switching threshold may be, for example, 100N.

In the case of central alignment of the load-bearing unit to the split-band ring, the fixation by the spreader unit takes place as far as possible without additional loading / unloading of the tension sensor.

According to a particularly advantageous embodiment of the invention, the control unit adapted to determine the position of the load-bearing unit to the split ring from the received data of the distance sensors and to adjust the position so that a difference in the distances is reduced.

The control unit receives the data from different, spaced distance sensors. If the control unit receives different distances from the distance sensors, the control unit is designed to adapt the position of the load-bearing unit by, for example, triggering the actuator in such a way that the difference in the distances is reduced. The control unit is preferably designed to determine the angle of inclination of the load-bearing unit on the basis of the data of the distance sensors. Particularly preferably, the control unit is designed to control the actuator so that it can advantageously adjust the inclination angle of the load-receiving unit to the position of the split ring.

in a schematic cross-sectional view of the binding device Fig. 6 while binding a slit band ring.

This in FIG. 1 illustrated handling device 1 shows a support frame 2, in which a load-bearing unit 3 is mounted rotatably mounted about a rotation axis 22. The support frame 2 and the load-bearing unit 3 are further connected to each other via two actuators 4a, 4b.

The load-bearing unit 3 is with its rear side 28 (see Fig. 2 and 3 ). At the rear side 28 opposite receiving side 23 (see Fig. 2 and 3 ), a split band ring 27 is attached. At the load-bearing unit 3, a spreader unit 5 with four Spreizarmen 6 and a transmission 7, consisting of a cross-shaped drive 8 and power transmission rods 9, respectively.

The transmission 7 is driven by two drive cylinders 30, wherein the cross-shaped drive 8 moves to spread the spreader unit 5 to the right. The power transmission rods 9 are connected to Spreizbolzen-holders 10. On the expansion pin holders 10 are each two expansion bolts 34 (see Fig. 4 ), which are connected via a thread (not shown here) with the Spreizbolzen-holders 10. In the Spreizarmen 6 a linear guide 11 is provided for the Spreizbolzen holder 10.

Next, four retaining arms 12 are arranged on the load-bearing unit 3, which - like the spreading arms 6 - are arranged at an angle of 90 degrees to each other. At each support arm 12, two holding elements 13 are arranged as a further holding device. The holding elements 13 may be formed, for example, as a vacuum holding elements to keep a slit band ring sucked by vacuum, or as a switchable permanent magnet elements, via a pneumatic system (not shown here) within a piston between the back 28 and the receiving side 23 of the load-bearing unit 3 moved back and forth and can be switched.

Each support arm 12 is equipped with an adjustment rail 14, in which the holding elements 13 are arranged and can be moved in the support arm 12.

Further, 12 inductive sensors 29 are arranged in the support arms, which the distance measure the load-bearing unit 3 when approaching the slit band ring 27 and transmit it to the control unit 15.

The actuator 4a, 4b consists of two piston-cylinder units 16a, 16b, each piston-cylinder unit 16a, 16b each having a first hinge 17a, 17b with the load-bearing unit 3 and a second hinge 18a, 18b with the support frame 2 is connected. Both piston-cylinder units 16a, 16b are provided with compressed air supply lines (not shown here), which can be controlled via the control unit 15.

Further, the handling device 1 is equipped with a handle unit 19a, 19b for guiding the manipulator 1. The handle unit 19a, 19b is constructed in two parts, wherein each part is connected to the support frame 2. At each part of the handle unit 19a, 19b, an operating unit 20a, 20b is arranged, via which a user can control the control unit 15.

The control unit 15 is fixedly connected to the support frame 2 and can control the drive cylinders 30 of the expansion unit 5, the actuator 4a, 4b, and the holding elements 13 for holding a split band ring via pressure lines (not shown here). The control unit 15 in turn can be controlled via the operating unit 20a, 20b. To attach the handling device 1, a holding eye 21 is welded to the support frame 2, which is connected via a pull load cell 31 with a crane hook 32.

FIG. 2 shows that in FIG. 1 illustrated handling device 1 schematically in a first side view. In the side view, the load-bearing unit 3 is shown, which is rotatably connected to the support frame 2. The rotation axis 22 of the load-receiving unit 3 is shifted from the center of the load-receiving unit 3 to the receiving side 23.

The FIG. 3 shows that in FIG. 1 illustrated handling device 1 with horizontally oriented load-bearing unit 3. The piston 24 of the actuator 4b is retracted into the cylinder 25. The load-bearing unit 3 has rotated about the axis of rotation 22 so that it is tilted with its upper end 26 in the direction of the receiving side 23 and assumes a horizontal position.

The operator can grasp the handling device 1 on the handle units 19a, 19b to receive a slit band ring 27 and control the actuator 4a, 4b with the aid of the control units 20a, 20b via the control unit 15 so that the load suspension unit 3 moves via the rotation axis 22 into a vertical position is turned. The operator leads by means of the handle unit 19a, 19b the handling device 1 to a slit band ring 27 zoom. As soon as the operator has guided the handling device 1 in the immediate vicinity of the slit strip ring 27, he activates the distance sensors 29, which determine the distances to the slit strip ring 27 and transmit them to the control unit 15. The control unit 15 receives the sensor data, processes it and tilts the load-bearing unit 3 automatically so that the load-bearing unit 3 is aligned parallel to the split-band ring 27. The distances measured by the sensors 29 are then equal to a preset tolerance threshold.

For fixing the load-bearing unit 3 on the split band ring 27, the operator can control the spreading unit 5 via the operating unit 20a, 20b. Due to a safety device, however, the control unit 15 releases the spreader unit 5 only for spreading, as soon as the distance sensors 29 have measured a sufficiently small and substantially equal distance of, for example, less than 3 mm in each case. After the triggering of the spreader unit 5 by the operator, the drive cylinders 30 pull apart the spreader unit 5.

The load cell 31 continuously transmits the load on the crane hook 32 to the control unit 15. Should the load measured by the tension measuring cell 31 increase by more than 100 N during the spreading, the control unit 15 automatically stops the spreading process and controls the crane (not shown here) in such a way that the handling device 1 is slightly lowered. As a result, a relief of the load cell 31 takes place. As soon as the additional load on the load cell 31 drops, for example, below 50 N, the control unit 15 transmits a control pulse to the spreader unit 5, and the spreader unit 5 continues the spreading. Should the load measured by the tension measuring cell 31 decrease by more than 100 N during spreading, the control unit 15 also automatically stops the spreading process and controls the crane in such a way that the handling device 1 is lifted slightly, so that the load of the handling device 1 returns the tensile load cell 31 acts. Once the burden For example, at the load cell 31 corresponds again to a certain specifications, the control unit 15 transmits a control pulse to the spreader unit 5 and the spreader unit 5 continues the spreading.

This alignment process can be repeated as often as required until the fixation of the split band ring 27 is completed via the spreader unit 5. Once the spreading process is completed, the operator receives a signal by which he knows that on the one hand the fixation of the split band ring 27 is completed and on the other hand, the control unit has released the holding elements 13 for driving. The operator activates the holding elements 13 via the operating unit 20a, 20b, so that the split-strip ring 27 is firmly connected to the load-receiving unit 3, depending on the design of the holding elements 13 by means of magnetic forces or by suction.

The control unit 15 can also be designed to automatically activate the retaining elements 13 as soon as the spreader unit 5 has completed the fixation of the split-band ring 27 and completes the fastening of the split-band ring 27.

After fastening, the control unit 15 releases the crane guidance to the operator. The operator can control the crane via the operating unit 20a, 20b and move the handling device 1 with the split ring 27 received. If necessary, the operator controls the actuator 4a, 4b via the operating unit 20a, 20b and the control unit 15, so that the load receiving unit 3 with the split band ring 27 is rotated about the axis of rotation 22 by retracting the pistons 24 into the cylinders 25. Following the rotational movement of the Kann can be controlled so that the handling device 1 is discontinued to a destination such as a pallet or a binding station.

In Fig. 5, 5a . 6, 7 a second embodiment of a handling device is shown as well as a binding device, which comprises a binding station 40 with a plurality of binding heads 44 in addition to the handling device 1. In this case, reference is made to the above description with respect to the description of the handling device 1. In the following, only the differences between the first and second embodiment of the handling device 1 will be described in more detail.

At the in Fig. 5a illustrated handling device 1, the expansion bolts 34 as well as the holding elements 13 are arranged on the Spreizarmen 6. The holding elements 13 are arranged on rail guides 79 along the spreading arms 6. The spreading arms 6 form a holding cross 77 which is pivotally mounted on the support frame 2 and is provided for receiving a split band ring 27.

Spiked turned to the holding cross a binding cross 78 with four binding arms 12 is arranged. The binding arms 12 each have a longitudinal channel 35, as in particular in cross section in Fig. 5b is clearly visible. The channel 35 serves to carry out a band during binding of a slit strip 27 accommodated on the load-receiving unit 3. It is formed and at the same time covered by cover plates 50, of which three pairs are arranged one behind the other in the longitudinal direction of the channel. The cover plates 50 overlap on the one hand in the transverse direction, as from Fig. 5b visible and on the other hand in the longitudinal direction. They close the channel to his in Fig. 5b upper, open side, so that an inserted band is guided within the channel 35. The cover plates 50 are each mounted by a spring holder 52 so that they swing away and thus can release the channel 35 as soon as the guided therein band is tensioned.

At the ends of the channels 33 each deflection pieces 54 are provided which deflect the tape in its course by 90 degrees in the direction of the channel 35.

In Fig. 6 the operation of the binding device is illustrated. Essentially vertically mounted slit strips 27 are gripped with the handling device 1 in the manner described, so that a slit strip 27 is securely fastened to the load-bearing unit 3 by the spreading device and the holding elements 13. By means of a crane, the handling device 1 with the recorded slit strip 27 is brought to the binding station 40 by guidance on the handle unit 19a, 19b. In this case, the load-bearing unit 3 is pivoted with the recorded slit strip 27 in the horizontal.

At the binding station 40 now the binding of the split band ring 27, while this remains fixed to the load-bearing unit 3. This is made possible by the channels 35 in the binding arms 12 of the load-bearing unit 3.

In schematic longitudinal section in Fig. 7 two binding heads 44 are shown, which are mounted floating on a machine bed in the radial direction and are therefore arranged freely displaceable in the longitudinal direction. A split band ring 27, held on the load receiving unit 3 of the handling device 1, is positioned above the binding heads 44. Centering receptacles 75 at the binding station, which cooperate with centering pieces 74 on the load-receiving unit and receive them in a centering position, serve for position-accurate, centric positioning.

Station-side deflection pieces 55 are provided on the binding station 40, which are vertically adjustable by means of a piston drive 56 and are extended from a first recessed rest position for binding the split band ring 27 in a binding position in which they together with the device-side deflection pieces 54 as in Figure 7 form a 180-degree deflection unit, so that the binding heads 44 can insert an endlessly supplied band 46 via the deflecting pieces 54, 55 in the channel 35.

The operator leads by means of the handle 19a, 19b, the handling device 1 to about the binding station 40 and controls the crane so that this guided by centering 75 and centering 74 is discontinued. A sensor, preferably an inductive proximity sensor (not shown), can monitor and display the correct positioning or release further handling steps only after correct positioning.

The centering recesses 75 are preferably retractable and are extended by a piston / cylinder drive for centering and accurate positioning. Under the guide thus formed, the operator places the gap band ring 27 further held on the load receiving unit 3 on the binding table. Then it activates the binding process, wherein first the station-side deflection pieces 55 are extended by the associated piston / cylinder drive 56 from the rest position until they abut against the device-side deflection pieces 54. In this case, it can preferably come to a vertical displacement of the binding cross 78, which is mounted vertically displaceable in this case relative to the holding cross 77 (not shown), so that with appropriate control of the drives 56 for different thicknesses of the split band ring 27 in each case at a certain distance between the binding arms 12 of the binding cross 78 and the split band ring 27 results. In the binding position reached in this way, all four binding heads 44 push simultaneously, as in Fig. 7 symbolically only shown on the left binding head by arrows, in each case before the binding band 46 in the direction of the deflecting pieces 54, 55, which is initially led around loosely around the split band ring 27 due to the arrangement of the deflecting pieces and the guide. The covers 50 are arranged longitudinally overlapping so that the tape does not abut against edges, but can be pushed out guided.

As soon as the advanced end arrives at the binding head 44 again, it is grasped. The arrival of the tape end is detected by a sensor. In order to release the binding heads 44 for the subsequent tightening of the belt, the drive 56 of the station-side deflection pieces 55 is driven so that they are sunk back into the rest position.

Thereafter, the tape guide rollers provided on the binding heads 44 are reversely operated, so that the belt 46 is pulled back and thus the formed belt loop 46 around the split belt ring 27 around as in Fig. 7 shown binding head 44 is shown tightened.

In this case, the resilient covers 50 of the channel 35 open and the slit strip slides transversely to the channel 35 out of this and lies tightly around the slit band ring 27. After tensioning the band this is separated on the binding head 44 from the rest of the supplied band 46 and the band loop formed welded by friction welding.

As in Fig. 6 shown schematically, four binding heads 42 are preferably arranged at 90 degrees to each other, so that the split band ring 27 is bound simultaneously at four points and thus well fixed.

In this case, the binding heads 44 center themselves due to the floating storage when tightening the belt 46 itself. This results in a uniform tightening of the belt.

The thus bound slit band ring 27 is further attached to the load receiving unit 3.

After binding, the operator can control the crane so that the handling device 1 is transferred with the bonded slit band ring 27, for example. On a shelf or on a pallet. For this purpose, the operator controls the crane accordingly and solves after discontinuing the Spaltbandringes 27 via the control panel 20a, 20b, the spreader 5 and then the holding elements 13. The handling device 1 is now ready to receive a new slit band ring.
