Embodiment Construction

[0022] see figure 1 , which shows a spring transfer device, generally designated 10 , adjacent to a spring winding machine 12 (shown only schematically). The transfer device comprises a transfer substrate in the form of a conveyor belt 14 arranged in an endless loop and driven in direction A by a motor 16 . The conveyor belt includes a plurality of magnetic spring holders 18 arranged to receive wire springs 20 from the winding machine 12 . Each magnetic spring holder has a pair of ferromagnets 18a for holding a steel spring. The magnets are arranged adjacent to each other with the same pole.

[0023] The device is arranged to cause the magnet to begin attracting the formed spring before the spring is cut from a length of wire by a spring winding machine.

[0024] At the bagging station, an electric hammer 22 having a plurality of fingers 22a - 22e pushes the spring from the spring retainer via the spring compression member 24 into position between the layers of bagging mate...

Abstract

Apparatus for transferring springs from a coiling machine to a pocketing station comprising a conveyor belt 14 with a plurality of magnets 18 positioned on it wherein the magnets 18 are arranged to attract and hold a spring. A mandrel may be provided for supporting the springs and the device may be arranged so that springs are held by a magnet 18 before being cut from a length of spring material. The springs may be deposited in discrete pockets 26 when leaving the conveyor 14. The magnets 18 may be arranged so that identical poles are adjacent to each other.

Description

technical field [0001] The present invention relates to devices and methods for transferring springs, and in particular to devices and methods for transferring springs from a winding device to an embedding station. Background technique [0002] Helical coil springs are used in many upholstered units, such as mattresses, to provide comfort. The springs may be wrapped in individual cloth bags to form a pocket spring unit. In general, the greater the number of individual springs, the more comfortable the user will be. In higher quality mattresses this leads to the use of smaller springs arranged densely in an array. International patent application number WO2007 / 031774 describes an example of a pocket spring unit and its method of manufacture. [0003] The spring is made in the coiling machine and can be stored until use, or it can be taken from the coiling machine and used directly in the assembly of the pocket spring unit. However, transfer and placement of small wire spr...
