Definitions

• the invention relates to a method for handling flexible hygiene products, in particular sanitary napkins, in which the hygiene products are transported continuously along a transport route and are thereby rotated, in particular erected, according to the preamble of claim 1.
• the invention relates to a corresponding device according to the preamble of claim 6.
• a disadvantage of such a solution is the space requirement. Due to the technology used, the length of these conveyor belts can be up to two meters depending on the product to be handled. As a result, the machine layout is large, although only simple conveying tasks have to be performed.
• Hygiene products are also very light and therefore have relatively low kinetic energy. Since the transport route usually runs horizontally for reasons of space, there is also no potential energy. Consequently, there is during transport of hygiene products, there is also a risk of machine malfunctions due to jams due to blockages in the conveyor line.
• the invention is based on the object of further developing methods and devices of the type mentioned at the outset, in particular with regard to eliminating the disadvantages known from the prior art.
• a method according to the invention for solving this problem has the features of claim 1. Accordingly, it is provided that the hygiene products are rotated by means of a rotating device arranged in the transport path, with a conveyor for the hygiene products preferably being arranged directly in front of and behind the rotating device and the rotating device having a shorter dimension in the transport direction of the hygiene products in the transport path than the products , So that the hygiene products are each transported by at least one of the two conveyors while they are rotated by means of the rotating device.
• the rotating device has guides against which the hygiene products rest during transport through the rotating device and with which the rotation of the hygiene products is effected during transport of the hygiene products through the rotating device.
• the hygiene products are fed lying flat between organs of the first conveying means of the rotating device and are erected in the rotating device and then transported away from the rotating device in an upright position between organs of the second conveying means, with the hygiene products doing so due to a shorter Dimension of the rotating device in the transport direction in relation to the corresponding dimension of the hygiene products are at least in engagement with the organs of the first conveyor or the organs of the second conveyor. Provision can furthermore be made for the hygiene products coming from a converter to be fed to the rotating device by means of the first conveying means, rotated there and transported in the direction of a stacker or excavator by means of the second conveying means.
• a device for solving the problem mentioned at the outset has the features of claim 6 . Accordingly, it is provided that the device has a rotating device arranged in the transport path for rotating the hygiene products, with a conveying means for the hygiene products being arranged, preferably directly in front of and behind the rotating device, and the rotating device having a shorter dimension in the transport direction of the hygiene products in the transport path than the hygiene products, so that the device is set up to transport the hygiene products with at least one of the two conveyors while the hygiene products are rotated by means of the rotating device.
• the rotating device is set up to rotate the flexible hygiene products, in particular by about 90°, namely around a longitudinal axis of the hygiene products, which runs essentially parallel to the transport direction or to the transport route, in particular in such a way that upstream and downstream ends of the hygiene products are arranged rotated by about 90° to one another in the rotating device.
• the device is set up to feed the hygiene products lying flat between organs of the first conveying means of the rotating device and to erect them in the rotating device and then upright them transported away from the rotary device standing between organs of the second conveyor, the hygiene products being in engagement with at least the conveyor belts of the first conveyor or the conveyors of the second conveyor due to the shorter dimensions of the rotary device in the transport direction in relation to the corresponding dimensions of the hygiene products.
• the rotating device has a housing which has walls along which the hygiene products slide at least during transport through the rotating device for rotating the hygiene products, with the course of the walls in the transport direction specifying the rotation of the hygiene products.
• the walls of the housing form a rigid channel, preferably closed laterally in the direction of transport, through which the hygiene products are transported.
• a special feature can be that the housing is formed from an upper half-shell and a lower half-shell, the half-shells being detachably connectable to one another, and it is preferably provided that the half-shells can be connected to one another by a quick-release fastener in the position forming the housing.
• the rotating device has a housing which has a slot running in the direction of transport, which is set up to enable transport faults in the rotating device to be eliminated from the outside.
