Definitions

  • the invention relates to a coil transport trolley with adjustable holding arms and a method for safely handling metal coils with a small outside diameter or sleeves on a reel mandrel.
  • Horizontally movable coil transport cars with vertically movable coil saddles are known from the prior art.
  • several support rollers can be arranged to accommodate a collar, each of which can be rotated axially about a horizontal direction.
  • Such coil transport trolleys are suitable for the safe handling (e.g. transport from a starting position to a target position, pushing onto or pulling off a coiler mandrel, etc.) of coils that have sufficient weight so that they do not tend to pop open without further shearing measures.
  • metal strips to be unwound from a reel mandrel are sometimes not completely unwound (e.g. with a reversing reel), but rather a remaining piece of the metal strip in question remains on the reel mandrel, which has to be transported away from it.
  • Such residual pieces if their outer diameter does not exceed a certain value d 0 , for example 750mm, are also referred to as so-called 'remaining bundles' and generally also have a correspondingly low weight.
  • the value d 0 is referred to below as the 'limit diameter'.
  • the coil saddle of a coil transport carriage is positioned against the underside of the remaining piece.
  • a separating cut is then made, by means of which the unwound part of the tape is separated from the part on the
  • the remaining piece of the reel mandrel is separated.
  • the remaining piece on the coiler mandrel is then wound back (ie rotated against the unwinding direction) to such an extent that the free band end comes to rest on the circumference near the collar saddle (so-called 5 o'clock or 7 o'clock position).
  • a respective coil is to be stabilized by means of two hold-down arms, the hold-down arms each exerting a hold-down force on the outer peripheral surface or in the coil eye of the coil.
  • a coil transport trolley is known with a clamping unit which can be retracted into the coil saddle and which, in the activated state, can press the metal coil against the coil saddle and thus stabilize its position by exerting a holding force in the coil eye of a metal coil placed on the coil transport trolley.
  • the EP 2 544 835 B1 discloses checking a high-strength collar to see whether it is in an unstable equilibrium position after being placed on two stationary support points and in this case to place a further, movable support point below the center plane of the metal collar against its outer peripheral surface. Since the collar is only held below its center plane and therefore not along more than half of its outer circumference, there is no positive connection to the support points, so that even a collar that has already been stabilized can open itself due to strong residual tension, for example caused by strong vibrations or thermal shrinkage of the federal government itself, cannot be ruled out with certainty.
  • a coiling device and a coiling method for a tape are known, in which the tape is coiled around a coil axis in the coiling device.
  • the coiled coil is secured in the coiling device against unintentional uncoiling by fixing the radially outermost turn with the aid of a safety device.
  • the secured bundle is removed together with the securing device from the reel device using a conveyor device.
  • the disadvantage here is that a separate safety device must be attached to each federal government, which may have to be removed again before further processing steps of the federal government.
  • the coil transport carriage for handling a coil on a coiler mandrel of a strip slitting system is known.
  • the coil transport carriage has a vertically movable coil saddle and pivotable holding arms, which are arranged in pairs opposite one another on the coil saddle. Using drives, the holding arms can be pivoted onto the collar in a direction parallel to the longitudinal axis of the collar, so that they stabilize it on the collar saddle using pressing elements. With the help of a cylinder, the coil transport carriage can be moved in a horizontal direction. The movements of the coil transport carriage and the holding arms are controlled fully automatically.
  • a coil saddle which can be moved vertically by means of a first drive unit.
  • several support rollers are arranged to accommodate a collar or a sleeve, the support rollers each being axially rotatable about a first horizontal direction X 1 .
  • the first horizontal direction X 1 coincides with the longitudinal axis of the reel mandrel.
  • the coil transport carriage also has holding arms for stabilizing the coil, in the event that its outer diameter is not larger than a limit diameter d 0 , or the sleeve.
  • the holding arms are arranged in pairs along a second horizontal direction X 2 opposite one another on the collar saddle, the second horizontal direction X 2 being oriented normal to the first horizontal direction X 1 .
  • the holding arms can be pivoted about the first horizontal direction .
  • the bundle transport carriage preferably has two or four holding arms. If the outer diameter of the collar exceeds a maximum limit diameter d 0 , the holding arms are not required.
  • the bundle transport carriage according to the invention has a second drive unit by means of which it can be moved horizontally.
  • the coil transport carriage can be moved towards the coiler mandrel and away from the coiler mandrel, for example to remove a coil from the coiler mandrel or to push a sleeve onto the coiler mandrel.
  • the horizontal direction along which the coil transport carriage can be moved by means of the second drive unit coincides with the first horizontal direction X 1 in the area of the reel mandrel or in the receiving area for a sleeve.
  • the bundle transport carriage according to the invention also has a control unit for actuating the first and second drive units and the rotary drives as well as a data technology interface for communication with a higher-level control unit.
  • the data technology interface enables the control unit of the coil transport vehicle to receive data relating to a transport process to be carried out from the higher-level control unit, which can be, for example, a system automation.
  • the data received from the higher-level control unit can only be in the form of key data for the upcoming transport process, for example the state m of the reel mandrel (collapsed or spread), dimensions a and / or weight g of the coil, a target position Z to which the coil is transported should be or a receiving position A at which a sleeve is to be taken over by the coil transport carriage.
  • the control unit is set up to automatically determine the time sequence and the control signals for the actuation of the first and second drive units and the rotary drives and carry out.
  • the parameters include, for example, the travel paths or the adjusting forces of the individual trades.
  • the control unit can also be set up to automatically determine, based on the status signal for the reel mandrel, whether a coil can be removed from the reel mandrel or whether a sleeve can be pushed onto the reel mandrel. For example, the control unit can automatically detect an impermissible operating state (e.g. if a coil is to be removed from the reel mandrel or a sleeve is to be pushed onto the reel mandrel, but the reel mandrel is still spread) and report it to the higher-level control unit via the data interface and wait for further control commands.
  • an impermissible operating state e.g. if a coil is to be removed from the reel mandrel or a sleeve is to be pushed onto the reel mandrel, but the reel mandrel is still spread
  • Further sensor signals e.g. light barriers for detecting obstacles
  • the control unit can automatically recognize an impending collision of the coil transport vehicle or part of it with an obstacle as an impermissible operating state and report the data interface to the higher-level control unit and interrupt or not start any transport process.
  • the rotary drives are designed as geared motors. Since the holding arms of the coil transport carriage have to perform a rotary movement to fix a coil or a sleeve, a combination of a motor with a rotating output shaft and a corresponding reduction gear can advantageously achieve a small design for the respective rotary drives, which reduces the risk of collisions Handling of a federal government or a sleeve is minimized.
  • the holding arms can be pivoted into a parking position P, so that the largest extension d max between the holding arms along the second horizontal direction X 2 is less than or equal to the largest dimension d btw of the bundle transport trolley along the second horizontal direction X 2 is.
  • the 'largest extension' d max between the holding arms along the second horizontal direction the parking position P.
  • pivoting the holding arms into the parking position means that the holding arms in the parking position P are not 'wider' than the bundle transport carriage itself if the width direction of the bundle transport carriage is equated with the second horizontal direction X 2 .
  • the bundle transport trolley according to the invention is therefore suitable as a replacement or retrofit solution for existing transport devices, since no structural changes to the corresponding route are required.
  • the holding arms are preferably designed in such a way that they positively stabilize collars or sleeves with an outer diameter that lies in a range between 500 mm and a limit diameter d 0 .
  • the limit diameter d 0 can for example 750mm. This is achieved by appropriately shaping the holding arms.
  • “Stabilizing in a form-fitting manner” is understood to mean that each of the holding arms of the coil transport carriage, when appropriately positioned by the rotary drives against the collar or sleeve located on the collar saddle, supports the collar or sleeve on the circumference at at least one point above a horizontal center plane Longitudinal axis M of the federal government or the sleeve is contacted.
  • the holding arms are preferably provided on their insides with a friction-reducing coating or sliding rollers.
  • a coil transport carriage in a first step S1 the coil saddle of the coil transport carriage is moved vertically by means of the first drive unit and against that located on the coiler mandrel
  • the coil which at this point is still connected to an unwound section of tape, is turned on so that the support rollers of the coil saddle contact the coil on its underside.
  • the adjustment of the collar saddle to the collar located on the coiler mandrel can, for example, be done in a force-controlled or position-controlled manner.
  • a position-controlled adjustment can take place either based on the corresponding collar diameter or based on a sensor signal (e.g. from a distance or touch sensor).
  • a force-controlled adjustment can be carried out using a force measuring device for the collar saddle based on the corresponding collar weight g or on the basis of a predetermined maximum positioning force.
  • a combination of force controlled and position controlled Employment is possible.
  • the relevant coil diameter or the relevant coil weight g can have been transmitted to the control unit of the coil transport vehicle via the data interface.
  • the coil saddle is set against the coil located on the coiler mandrel with a force that corresponds to the weight of the coil after the uncoiled band section has been separated: this relieves the coiler mandrel of the weight of the coil, so that it can easily be removed from the coil in a subsequent step
  • the reel mandrel can be removed because if the reel mandrel collapses, no elastic deflections - caused by the weight of the federal government or by an excessive contact force of the federal saddle - have to be compensated for.
  • the holding arms are pivoted onto the collar by means of the rotary drives.
  • the holding arms can be pivoted onto the collar, for example, by applying a certain torque, so that it is ensured that the holding arms actually contact the outer peripheral surface of the collar.
  • the free band end which is created in a subsequent third step S3 by separating the unwound band section from the collar, is pressed against the outer peripheral surface of the collar and mechanically secured against uncontrolled falling or jumping up.
  • the uncoiled band section is separated from the coil in the third step S3 by means of a separating device which is arranged to the side of the reel mandrel - i.e. in a direction transverse to its longitudinal axis.
  • a fourth step S4 of the method according to the invention the coil is rotated with the aid of the reel mandrel against an unwinding direction U of the coil until the free tape end of the coil is positioned on the circumference within a predetermined angular range ⁇ max relative to the vertical through a longitudinal axis M of the coil.
  • the angular range ⁇ max can be determined by the geometric arrangement of the support rollers of the collar saddle, so that the free band end is positioned, for example, a maximum of 20cm from one of the support rollers (so-called 5 o'clock or 7 o'clock position).
  • the free band end When turning the collar against an unwinding direction U, the free band end is preferably not rotated over one of the support rollers in order to avoid indentations of the band edge into the underlying layers of the collar.
  • the unwinding direction U of the coil means the direction of rotation in which the coil is rotated when unwinding from the coiler mandrel.
  • the coiler mandrel When the coiler mandrel is spread, there is mechanical contact between the coiler mandrel and the coil in its coil eye. Therefore, subsequently, ie after rotation against the unwinding direction U, the previously spread reel mandrel collapses (ie its outer diameter is reduced, so that there is no longer any mechanical contact between the reel mandrel and the collar).
  • a subsequent fifth step S5 of the method according to the invention the coil transport carriage is moved away from the coiler mandrel by means of the second drive unit until the coil is completely removed from the coiler mandrel, so that no part of the coiler mandrel protrudes into the coil eye of the coil.
  • the coiling mandrel is rotated against the unwinding direction U in order to avoid the inner winding of the coil from getting caught on the coiling mandrel.
  • the bundle is transported by the bundle transport carriage to a target position, for example a binding station, by activating the second drive unit.
  • step S5 ' which is carried out between the fifth and sixth steps S5 and S6, the collar saddle is lowered vertically by means of the first drive unit. This increases the mechanical stability of the coil transport carriage along the second horizontal direction X 2 during the transport process.
  • control unit of the bundle transport carriage receives data from a higher-level control unit via the data interface, on the basis of which the control unit actuates the first and second drive units and the rotary drives, so that the sequence of steps S1 to S6 is carried out.
  • the data received from the higher-level control unit can only be present in the form of previously described key data of the upcoming transport process.
  • the data can include the state m of the coiler mandrel, dimensions a of the coil on the coiler mandrel, a coil weight g or a target position Z to which the coil is to be transported after being pulled off the coiler mandrel.
  • control unit is set up to automatically determine and carry out the time sequence and the control signals for the actuation of the first and second drive units and the rotary drives, so that the sequence of steps S1 to S6 is carried out autonomously by the coil transport vehicle or its control unit , which is referred to as the so-called fully automatic operating mode of the coil transport car.
  • the advantage of this is that the control and monitoring effort for the respective bundle transport on the higher-level control unit is minimized.
  • control unit of the bundle transport carriage can also receive corresponding data packets from the higher-level control unit via the data technology interface for individual sub-steps of the transport process to be carried out, for example for each of the above-mentioned steps S1 to S6, the control signals for the actuation of the first and second Drive unit and the rotary drives are determined by the control unit of the coil transport car, but the timing of the individual sub-steps is specified by the higher-level control unit. This corresponds to a semi-automatic operating mode of the coil transport car and offers greater flexibility in terms of the timing of a transport process.
  • control unit of the bundle transport carriage can also receive the control signals for the actuation of the individual trades, such as the first and second drive units and the rotary drives, directly via the data interface from a higher-level control unit or an operator (e.g. by pressing appropriate buttons or switches).
