Definitions

the present invention relates to a device for producing a pocket spring core according to the preamble of claim 1.
Such a device makes coil springs for pocket spring cores produced, spring wire brought into a wind station via a feed device in which a coil spring is wound, which is cylindrical, but in particular is barrel-shaped.
the respective coil spring After the respective coil spring has been wound, it is connected to a turn of gripped the gripper of the gripper arm and, for example, a heat treatment station fed, in which the structure changed by the winding is normalized, so that the original spring properties of the spring wire are restored become.
the heated spring then runs through a cooling section until it is in another Processing station pocketed in a fabric covering in the broadest sense is, so that a row of springs is formed, either the length or the width of the spring core corresponds.
the different zones are in one extent defined by the length of the rows of springs, i.e., either by the total length of the innerspring, or its total width.
Partial zones that is, those provided, so to speak, island-like in the spring core are, can not be produced with the known devices.
the present invention is therefore based on the object of a device of the generic type so that a simpler and cheaper Manufacture of a spring core with different strength zones possible and the design options of the zones with regard to their arrangement and Configuration within the innerspring is improved.
the gripper arm or the wind station is adjusted by means of a servomotor. which can be operated under computer control, so that one after the other Coil springs can be made that have different numbers of turns have, the length of the individual coil springs, from which the height of the spring core, regardless of their number of turns, is approximately the same.
Such manufacture allows the manufacture of a spring core, in which, depending on Need, for example zones of different strength in the input mentioned island-like configuration can be made.
the wind station has a second feed device is assigned to one in relation to the first feed device Thickness of different wire is fed, whereby a coil spring can be produced which also differs in strength from another. In combination with different numbers of turns, there are therefore many Differences in strength of the zones can be made. But also spring cores that differ in their entirety from others in terms of their strength, are without significant retrofitting of the device, let alone without one to manufacture additional device.
a further development of the invention also contributes to this, according to which the Coil springs with different winding directions are manufactured.
the Coil springs with different winding directions are manufactured.
the single figure shows a partial section of a device according to the invention in a schematic top view.
the figure shows a device for producing a pocket spring core, which has a wind station 6 with which a helical spring 1 can be produced is.
a large number of coil springs 1 are placed in adjacent pockets a textile or textile-like covering, not shown, used a predetermined number of the coil springs inserted into the pockets Series of springs result, of which several form a pocket spring core with each other get connected.
a feed device 7 is assigned to the wind station 6, through which the wind station 6, a spring wire 8 is supplied, from which the coil spring 1 is wound becomes.
a gripper arm 2 For transporting the coiled coil spring 1 into a downstream heat treatment device 9, a gripper arm 2 is provided, which is on a pivot axis 4, which is movable via a rotary drive 5, is mounted.
the gripper arm 2 has at its free end a gripper 3 with which the Coil spring 1 is gripped and held on a turn so that it is complete the wind station 6 from its area into the heat treatment device 9 can be transported.
the gripper arm 2 is so adjustable on the pivot axis 4 stored that the distance between the gripper arm 2 and with it the gripper 3 to the wind station 6 is changeable.
the number of turns is dash-dotted coil spring 1 shown larger than that shown in full line.
the gripper arm 2 which is then the coil spring 1 with a larger number of turns seizes, also recognizable by dash-dotted lines.
the adjustability of the gripper arm 2 indicated by arrows can be determined by a Actuator, not shown, take place, the computer-controlled position of the gripper arm 2 changed so that the number of turns of the coil spring 1 as desired is selectable.
a coupling of the servomotor for changing the position of the gripper arm 2 with the Wind station 6 makes sense. This gives you the option of running while Production, i.e. without stopping the device in its number of turns to produce different coil springs 1 easily and to a pocket spring core to process.
