Brief Patent Description - Full Patent Description - Patent Application Claims
FIELD OF THE INVENTION [0001] The invention relates to a method and a device for transferring springs into holding means of an assembler, according to the preamble of patent claims 1 and 7. PRIOR ART [0002] In the manufacture of spring cores for mattresses, paddings or seat cushions, springs are wound in a spring winding machine, transferred via a spring winding station to a spring conveyor and fed by the latter via a transfer device to an assembly device. which is also called an assembler. In this assembly device, coil wires are guided through the individual spring rows and the individual springs are thus connected to one another to form spring cores. [0003] DE-A-24 13 033 discloses an assembler of this type. U.S. Pat. No. 3,774, 652 describes a transfer device which has rotary tables, in order to rotate the springs into desired positions before they are transferred into the assembler. [0004] DE-A-1 552 150 discloses a transfer device which has individual gripping arms for transferring individual springs, the gripping arms being guided in a slotted guide track. [0005] If springs are missing, a spring is oriented incorrectly or other faults occur, this fault has to be corrected by hand in the region of the assembler. However, the transfer device impedes free access to the assembler and therefore has to be removed first of all in a relatively laborious manner. This leads to a relatively long interruption of production whenever a fault occurs. [0006] Furthermore, DE-A-195 42 844 discloses a transfer device having a sliding bar which is connected to a rotational pin via a lever. Here, a rotation of the rotational pin is converted into a horizontal displacement of the bar. Individual slides which bear against inner sides of a respective run of a belt conveyor under spring loading are arranged on the bar. The springs which are delivered clamped between these belt conveyors can be pushed out of the region of the belt conveyors into assembly tongs by means of these slides. When a fault occurs in this system, the assembler is removed by being pushed away from the transfer device which is connected to the conveyor. As a result, the operating personnel can move into a gap between the belt conveyor and the assembler and fix the fault. This is relatively time-consuming and complicated. [0007] Furthermore, the transfer device or parts thereof usually also have to be exchanged if the type and shape of the springs are changed. This exchange is often time-consuming and complicated in the known transfer devices. SUMMARY OF THE INVENTION [0008] It is therefore an object of the invention to provide a method and a device for transferring springs into holding means of an assembler, which method and device make access to the transfer station possible in a simple manner. [0009] This object is achieved by a method and a device having the features of patent claims 1 and 7, respectively. [0010] In the method according to the invention for transferring springs, the latter are delivered in a conveying direction by means of a spring conveyor arranged one behind another in a row and are transferred in groups and perpendicularly with respect to the conveying direction into the holding means of the assembler. Here, they are delivered directly from the spring conveyor into the assembler with avoidance of a dedicated transfer device. For this purpose, the spring conveyor protrudes into the assembler. A sliding bar which is used for transferring the springs from the spring conveyor to the assembler can be removed from the transfer region in a simple manner; in particular, it can be lowered. Faults during transfer can thus be fixed in a simple manner. [0011] Furthermore, it is advantageous that the size of the system is minimized. [0012] Furthermore, it is an object of the invention to provide a method and a device, the sliding bar of which can be moved relatively simply and can be exchanged in a simple manner. [0013] This object is achieved by a method and a device having the features of patent claims 3 and 9, respectively. [0014] In this method and this device, the springs are displaced by means of the sliding bar, by the sliding bar being displaced along a horizontal path which is predefined by at least one slotted guide track, for transferring the springs. This variant or embodiment can also be used in a dedicated transfer device, for example in a system which has a spring conveyor, an assembler and the transfer device, the spring conveyor running between the assembler and the transfer device. [0015] Further advantageous variants of the method and advantageous embodiments emerge from the dependent patent claims.
