Definitions

  • the invention relates to a spring transport device with servo drive according to the preamble of claim 1, (see e.g. GB-A-1152 072).
  • Such machines are used to make a finished Spring suitable for processing and in the exact position of a facility to supply in which facility the springs to one Innerspring, a cushion or a seat cushion become.
  • Characteristic of such a spring insertion station is that of a spring manufacturing machine, which is within the scope of the present Invention is no longer described, a spring in each a gripping hand of a multi-armed transport star is and this spring now via a spring insertion station and various other downstream stations of the Assembly machine is fed.
  • the spring produced in this station is in the respective gripping hand of the transport star inserted and there clamped and sent for further processing.
  • the subsequent spring insertion station works so that swivel jaws in the outlet area of the respective Gripping hand of the transport star were present, which Swivel jaws between them take up the spring, the Spring from the gripping hand of the transport star into this Swivel jaws were inserted.
  • Swiveling movement of the jaws in the area of Spring insertion station had the disadvantage that there spring inserted into the spring insertion station is never precise enough could be positioned. This was with the downside connected that the spring over a larger number of subsequent straightening stations had to be precisely aligned, which was associated with increased machine expenditure.
  • the invention is therefore based on the object Spring transport device of the type mentioned above continue to form that the entire transport facility can be designed more cost-effectively, in particular with the goal that also the individual adjustment of the distance between the individual springs with simple means is adjustable.
  • An essential feature of the invention is that of one central drive based on two synchronously driven Ribbon loops are present, with each ribbon loop one forms upper and a lower run and that the to transporting spring in the facing each other Trums of the two synchronously arranged ribbon loops clamping is inserted and transported under compression.
  • the drive is a servo drive is designed or optionally as a stepper motor, which makes it is now possible for the first time in the area of the insertion station Insert the spring so that you have a constant loading cycle and has transported the belt at different speeds so different and individually adjustable To maintain distances between the individual springs.
  • This transfer device therefore no longer has to Align springs individually afterwards, but instead receives the already individually aligned springs with their respective spring spacing allocated correctly so that only a simple slide system ensures that a series of springs that are already in the correct position Transfer device are fed a downstream Assembly machine to be handed over.
  • Figure 1 it is shown that a transport star from a multi-arm gripper mechanism consisting of a number of Gripping hands 18 at the respective free end, wherein in each gripping hand 18 inserted a corresponding spring 26 and is held there clamped.
  • the gripping hand guides the spring 26 into a spring insertion station 2 a.
  • a first straightening station 4 is at the outlet of the turning station arranged that only checks as a control station whether the knot of the spring 26 correctly in the spring insertion station 2 was positioned.
  • Another straightening station 5 ensures that each of a series of one after the other in the area of the belt loops 8, 9 arranged springs each the last spring of the previous row is pulled out, this turns and pushes it back in as the first spring in the next row the band gap of the band loops 8, 9.
  • a transfer device 6 is located behind the straightening station 5 arranged, in which the springs lie in the correct position one behind the other following with a cross slide system in a cross to the Belt loops 8, 9 handed assembly machine become.
  • the belt loop 8 is above the respective deflection roller 14, 15 and 9 led.
  • Each ribbon loop consists of an upper and lower strand, and between the facing dreams of these Belt loops 8, 9, the spring 26 to be inserted is inserted.
  • the belt drive 7 is freely programmable, the Drive motor can also be designed as a stepper motor and it is possible with the same insertion speed the transport star 1 in the band by appropriate Varying the tape drive speed the distance between adjust the springs precisely and at will.
  • the two belt loops 8, 9 run over front ones Deflection rollers 16, 17 and are deflected there.
  • Figure 3 shows schematically a turning station with it is possible horizontally in the spring insertion station to insert inserted springs 26 into a vertical position. This is shown in FIG. 3 using the springs 26, 26a, 26b, 26c shown.
  • the turning station consists of the two synchronously driven belt loops 8, 9, of which the belt loop 8 has an inner run 8a and an outer run 8b, too the belt loop 9 has an inner run 9a and an outer run Trums 9b.
  • the tape guide of the turning station 3 for is schematized the ribbon loop 9 is shown, the ribbon loop 8.9 is exactly the same, and therefore are for the same Parts with dashed position numbers have been used.
  • the outer run 9b runs over a first deflection roller 21, each with a vertical Axis of rotation is formed and via a second deflecting roller 22 with an inclined axis of rotation.
