- 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.
- FIG. 1 shows a device for handling sanitary napkins in a schematic three-dimensional representation
- Fig. 2 shows a partial side view of the device according to arrow II in Fig.
- FIG. 3 shows a vertical section through the device along section line III-III in FIG. 1
- Fig. 5 shows a vertical section through the device along section line V - V in Fig. 2,

- hygiene products 10 are products such as (sanitary) towels or the like. In particular, it is about the handling of flat, flexible hygiene products 10.
- the hygiene products 10 are preferably processed unfolded.
- the hygiene products 10 are transported continuously along a first transport path 11 in a first transport direction 12 .
- the hygiene products 10 are transported lying flat and at a distance from one another.
- the hygiene products 10 are transported along a second transport path 13 in a second transport direction 14 .
- the second transport section 13 and the second transport direction 14 run transversely to the first transport section 11 and to the first transport direction 12.
- a compartment conveyor 15 is provided along the second transport section 13 and has compartments 16 for receiving one or more hygiene products 10 .
- the compartments 16 are delimited by partitions 17 transversely to the second transport direction 14 .
- the hygiene products 10 are arranged upright in the compartments 16 of the compartment conveyor 15 . Consequently, it is necessary for the hygiene products 10 that are supplied lying flat to be erected accordingly.
- a turning device 18 which is located in the first transport section 11 , is provided for erecting the hygiene products 10 .
- the hygiene products 10 are rotated from the flat to the upright position by the rotating device 18 during transport.
- the rotating device 18 has a correspondingly shaped channel 19 through which the hygiene products 10 are transported and rotated as desired by contacting the walls 20 of the channel 19 .
- the walls 20 thus serve as guides for the hygiene products 10.
- the hygiene products 10 are also turned on themselves, in particular in such a way that an entry-side end of a hygiene product 10 is arranged lying flat, whereas the exit-side end of the hygiene product 10 is arranged upright.
- the hygiene products 10 can be rotated through 90° with the aid of the rotating device 18 .
- larger or smaller angles of rotation are also possible by appropriate design of the rotary device 18 .
- a rotation from a lying flat to an upright position does not necessarily have to take place.
- Other relative positions, also in combination with other angles of rotation, are also conceivable.
- the construction can be set up in such a way that the hygiene product 10 is in engagement with at least one of the two conveying means 21, 22 during transport through the rotating device 18.
- the distance 23 between the conveying means 21, 22 can be set up accordingly. Accordingly, the distance between the conveyors 21, 22 before and after the rotating device 18 is less than or equal to the product length.
- the rotating device 18 or the walls 20 can be designed in the manner of a housing 24 .
- the housing 24 is preferably designed in two parts, with an upper half-shell 25 and a lower half-shell 26. This enables the housing 24 to be opened in order to clean the duct 19 or eliminate transport problems.
- the housing 24 is designed in one piece and has a slot 27 running in the longitudinal direction, through which access to the channel 19 is possible, for example for the purposes mentioned above.
- the third variant of the rotating device 18 shown in FIG. 8 has a pivotably mounted upper half-shell 25 which can be secured on the lower half-shell 26 by means of a quick-release fastener 28 .
- slot 27 and/or the quick-release fastener can also be provided in combination with the first exemplary embodiment.
- the housing is preferably produced using a 3D printing process.
- the housing 24 may be closed, as shown, apart from an inlet opening and an outlet opening.
- the housing 24 or its walls 20 is or are only formed by web-like guides on which the hygiene products 10 then rest.
- the first conveyor 21 is formed by a pair of driven rollers
- the second conveyor 22 is formed by a pair of endless conveyor belts. The hygiene products 10 rest between the two rollers or between the two conveyor belts. It goes without saying that other suitable transport means can also be used as the first and second conveyor means 21 , 22 .
