Definitions

  • the present invention relates to a spring transfer device for the transfer of springs from a spring coiling machine.to a spring transport unit and a spring transfer method.
  • the invention relates to such a spring transfer device that may be used in a machine for manufacturing spring core units, e.g., spring core units for mattresses.
  • Conventional machines for manufacturing spring core units comprise a spring coiling machine, a spring transport unit, and a spring core assembling machine as basic units.
  • springs are coiled, knotted or bended and tempered.
  • a transport star with a plurality of transport arms with grippers or hooks at each transport arm forwards the springs from the spring coiling machine to the transport unit.
  • the transport unit may comprise a pair of spaced and parallel conveyor belts, the springs being inserted one after the other from the transport star between the conveyor belts so that the conveyor belts transport the springs as rows of aligned springs to the spring core assembling machine.
  • the rows of aligned springs are assembled to form the finished product, i.e., the corresponding spring core unit.
  • EP 2 316 783 A1 discloses a spring transfer device for the transfer of the springs from the transport star to the spring transport unit, in which the springs are pushed one after the other by means of pushers from the transport star between pairs of spaced rotary plates, the rotary plates allowing for a rotation of the corresponding spring held between the rotary plates around its longitudinal axis.
  • This allows that the knots and/or ends of the springs are brought into a desired position on the conveyor belt, so that the knots and/or ends of the springs can be easily aligned individually for the assembly in the spring core assembling machine. For example, it is often desirable to arrange the springs in pairs with the knots or spring wire ends lying opposite to one another.
  • outer springs in a row of springs are usually rotated by 180 degrees about their longitudinal axes so that the free ends or the knots of these springs are aligned towards the respective adjacent spring in order to prevent that the ends of these outer springs penetrate through the mattress material.
  • the springs are transferred from the rotary plates to the conveyor belts by means of a further pusher, and the conveyor belts are guided along a 90° deflection such that the springs are brought from their horizontal orientation to a vertical orientation in which they are conveyed to the assembling machine.
  • a spring transfer device according to the preamble of claim 1 is known from WO 2005/077563 A1 .
  • a spring transfer device for transferring a spring from a spring coiling machine to a spring transport unit, the spring device being configured such that it takes over the spring from the spring coiling machine at a first location and moves the spring to a second location for transfer to the spring transport unit.
  • the spring device comprises a pivot mechanism for pivoting the spring, during the movement from the first location to the second location, from a first orientation, which the spring has at the first location, to a second orientation, which the spring has at the second location and which is substantially perpendicular to the first orientation.
  • the first orientation is a horizontal orientation and the second orientation is a vertical orientation of the spring.
  • the spring transfer device may be configured such that it takes over the spring from one of a plurality of transport arms of a transport star, the transport star being rotated further by one transport arm per operating cycle and each transport arm of the transport star transporting one spring from the spring coiling machine to the spring transfer device.
  • the pivot mechanism is configured such that it swings or pivots a base member from the first location, where the spring has the first orientation, to the second location, where the spring has the second orientation, and back from the second location to the first location during each operating cycle.
  • the pivot mechanism is preferably configured such that it moves the spring from the first location to the second location by a combined pivoting and translational movement, the first location being spaced from the second location along both a width direction and a height direction of the spring transfer device.
  • the spring transfer device comprises a rotating mechanism for rotating the spring about its longitudinal axis while the spring is moved by the pivot mechanism from the first location to the second location and is pivoted from the first orientation to the second orientation. This allows that, once the pivoting by 90 degrees from the first orientation to the second orientation is completed and the respective spring has been moved from the first location to the second location, the knots of each spring are already in the correct position to undergo the spiral process in the assembling machine.
  • each spring is transferred from the first location, where it is taken over from the spring coiling machine, to the second location, where is can be transferred to the spring transport unit.
  • the spring is simultaneously brought from its first orientation into its second orientation that allows the transport by the spring transport unit to the spring core assembling machine without need for any further re-orientation or alignment means.
  • the spring is rotated about its longitudinal axis so as to align the position of its ends and knots as desired. As these movements are done simultaneously, the spring transfer device requires less space than prior art devices.
  • the spring transfer device of the invention allows for ergonomic operations as the springs come out of the spring transfer device at the correct height to be processed by the spring core assembling machine. Only very few adjustments are required if the spring height varies.
  • the pivot mechanism may comprise a pair of holding members, preferably in the form of rotary disks or rotary plates, which are spaced from one another such that they can take over the spring at the first location, hold it between the pair of holding members and rotate the spring about its longitudinal axis by rotation of the holding members.
  • the holding members are preferably attached to the base member of the pivot mechanism so that they are moved and pivoted together with the base member.
  • the pivoting or swinging base member of the pivot mechanism is arranged movably along a fixed elongate shaft, the shaft having a curved groove where the base member engages the shaft so that the base member is pivoted from the first orientation to the second orientation when being moved along the shaft.
  • the curved groove is substantially S-shaped.
  • An eccentric drive mechanism may be provided for moving the base member along the shaft.
  • the present invention also provides a spring core manufacturing machine which comprises a spring coiling machine for providing coiled springs, a spring core assembling machine for manufacturing a spring core from a plurality of rows of coiled springs, a spring transport unit for transporting rows of aligned coiled springs to the spring core assembling machine, and a spring transfer device for taking over one spring from the spring coiling machine and transferring the spring to the spring transport unit during each operating cycle of the spring core manufacturing machine, the spring transfer device having the features of the above described spring transfer device.
  • a method for transferring a spring from a spring coiling machine to a spring transport unit comprises the steps of taking over the spring from the spring coiling machine at a first location, moving the spring to a second location for transfer to the spring transport unit, and pivoting the spring from a first orientation, which the spring has at the first location, to a second orientation, which the spring has at the second location and which is substantially perpendicular to the first orientation, during the movement step.

  • the machine shown in Fig. 1 comprises a wire swift 100 that supplies wire for the manufacture of coiled springs to a spring coiling machine 200.
  • the spring coiling machine 200 processes the wire and manufactures coiled springs which are knotted at both ends. Furthermore, in the spring coiling machine, the coiled springs are tempered.
  • the springs are forwarded from the spring coiling machine 200 to a spring transport unit 300 which transports rows of aligned springs to an assembling machine 400.
  • the rows of aligned springs are assembled to form a finished product 500, i.e., a corresponding spring core unit.

  • a spring transfer device 50 is provided for the transfer of the springs from the spring coiling machine 200 to the spring transport unit 300.
  • the machine comprises a transport star 10 having a plurality of transport arms to provide the springs from the spring coiling machine 200 to the spring transfer device 50.
  • the transport star is step-wise or cycle-wise rotated so that, during each cycle of the machine, one of the transport arms of the transport star 10 receives a new spring from the spring coiling machine 200 and one other transport arm forwards another spring to the spring transfer device 50.
  • the spring transfer device preferably is configured such that, during each operating cycle of the machine, it takes over the spring at a first location from the respective transport arm of the transport star 10 and moves the spring to a second location where the spring is transferred to the spring transport unit 300.
  • the spring transfer device 50 moves the spring received from the transport star 10 to the second location and simultaneously swings or pivots the spring from a horizontal first orientation to a vertical second orientation so that the spring reaches the spring transport unit 300 already in the desired vertical orientation. Furthermore, during the same cycle, the spring transfer device 50 swings back or returns to the first location so that it is ready to take over a spring from the next transport arm of the transport star 10 during the next operating cycle of the machine.
  • the spring transport unit 300 comprises a pair of parallel and spaced conveyor belts 41, 42 which extend in the longitudinal direction or width direction of the transport unit 300.

  • Fig. 3 shows the spring transfer device 50 in a state where it has already moved a spring 30 to the second location for transfer to the conveyor belts 41, 42 of the spring transport unit 300.
  • the transport star 10 with some of its transport arms 11 that are arranged spaced along the circumferential direction of the transport star.
  • Each transport arm 11 has a gripper or hook 12 at its end portion and forwards a spring 30 from the spring coiling machine 200 to the spring transfer device 50 such that, when the spring transfer device takes over this spring 30 from the respective transport arm 11 at the first location, the spring 30 has a horizontal orientation.
  • the spring transfer device 50 moves the spring 30 to the second location shown in Fig. 3 and, thereby, pivots the spring 30 so that the spring has a vertical orientation at the second location and, thus, can be easily drawn in between the two conveyor belts 41, 42.
  • the spring transfer device 50 is configured such that the movement of the spring 30 from the first location to the second location is a combined pivoting and translational movement. This means that the orientation of the spring at the second location is not only substantially perpendicular with respect to its orientation at the first location, but the second location is also spaced from the first location both in the width direction and in the height direction of the arrangement shown in Fig. 3 .
  • the spring transfer device 50 returns during the same cycle to the first location so as to receive, in the following cycle, another horizontally oriented spring from the next transport arm 11 of the transport star 10.
