Definitions

the present invention relates to a device for producing a pocket spring core according to the preamble of claim 1.
helical springs for pocket spring cores are produced, spring wire being brought into a wind station via a feed device, in each of which a helical spring is wound, which is cylindrical but in particular barrel-shaped.
the heated spring passes through a cooling section until it istienttascht in another processing station in a broad sense tissue wrapping, so that a spring row is formed, which corresponds to either the length or the width of the spring core.
a plurality of spring rows are connected to said spring core with each other. This can be done by stapling or gluing.
the different zones are defined in their one extent by the length of the spring rows, i.e., either by the total length of the spring core, or its overall width.
Partial zones ie those which are provided, so to speak island-like in the spring core, can not be produced with the known devices.
the present invention is therefore based on the object, a device of the generic type in such a way that a simpler and more cost-effective production of a spring core with different strength zones is possible and the design possibility of the zones is improved in their arrangement and configuration within the spring core.
the gripper which, as mentioned, the ready-wound coil spring grasps a turn, can be positioned accordingly. This ensures that the coil spring is correctly gripped for further transport in each case.
the adjustment of the gripper arm or the Windestation can be done by means of a servomotor, which can be operated under computer control, so that quite successively coil springs can be manufactured, which have different numbers of turns, the length of the individual coil springs, which results in the height of the spring core, regardless of their number of turns, is about the same.
Such manufacturing allows the production of a spring core, in which, for example, zones of different strength in the input mentioned island-like configuration can be produced as needed.
the wind station is associated with a second feed device, which is supplied with respect to the first feeder in its thickness different wire, whereby a coil spring can be produced, which also differs in their strength over another.
a coil spring can be produced, which also differs in their strength over another.
spring cores the are different in their entirety from others in terms of their strength, are without appreciable conversion of the device, let alone to manufacture without an additional device.
a further embodiment of the invention also contributes to this, according to which the coil springs are produced with different winding directions. For this purpose, in addition to a changed feed direction of the wire, an altered direction of rotation of the wind station is required.
the coil springs are wound right or left, also a higher strength of the spring core is achieved in total, but at least a "swimming" by transverse displacement of the two broad sides of the spring core largely avoided.
pocket spring core with different strength zones which consists of a plurality of interconnected spring rows, each used in juxtaposed pockets of a textile or textile-like sheath consisting of spring wire coil springs, the number of turns and / or the diameter of the Wire and / or the winding direction of the coil springs partially different.
the single FIGURE shows a partial section of a device according to the invention in a schematic plan view.
an apparatus for producing a pocket spring core which has a Windestation 6, with which a coil spring 1 can be produced.
a plurality of coil springs 1 are used in each adjacent pockets of a textile or textile-like enclosure, not shown, wherein a predetermined number of inserted into the pockets coil springs result in a row of spring, several of which are connected to a pocket spring core.
the wind station 6 is associated with a feed device 7, through which the wind station 6, a spring wire 8 is fed, from which the coil spring 1 is wound.
a gripping arm 2 For transporting the coiled coil spring 1 in a downstream heat treatment device 9, a gripping arm 2 is provided, which is mounted on a pivot axis 4 which is movable via a rotary drive 5.
the gripper arm 2 has at its free end on a gripper 3, with which the coil spring 1 is detected and held on a turn, so that they can be transported after completion of the Windestation 6 from the area in the heat treatment device 9.
the gripper arm 2 is mounted so adjustable on the pivot axis 4, that the distance between the gripping arm 2 and with it the gripper 3 to the wind station 6 is variable.
the number of turns of the dash-dotted coil spring 1 is greater than that shown in full line.
the gripper arm 2 which then takes the coil spring 1 with a larger number of turns, also identified by dash-dotted lines.
the indicated by arrows adjustability of the gripper arm 2 can be done by a servo motor, not shown, the computer controlled changes the position of the gripper arm 2, so that the number of turns of the coil spring 1 is arbitrary selectable.
a coupling of the servomotor for changing the position of the gripping arm 2 with the wind station 6 is useful. This makes it possible, during the current production, ie without the device to shut down in their Windungsanquip different coil springs 1 easily produce and process into a pocket spring core.
