    description
    The invention relates to a toothed belt drive and an arrangement of toothed belt drives for transport in the context of a manufacturing and / or packaging process, as is known, for example, from the production of food products, in particular from the production of cheese mass filled into a film tube.
    Such a toothed belt drive is described in DE 33 05 504 C2, which, compared to drives known at the time, enables a significant reduction in operating noise, especially at high speeds and wide toothed belt belts. Such operating noises occur above all when the toothed surfaces of the conveyor belts and the toothed drive rollers interlock and the air between the "teeth" has to escape. For this purpose, DE 33 05 504 C2 describes escape routes for the air at the Gear wheels are provided which are designed as grooves running transversely to the direction of rotation of the gear wheels and radially around the gear wheels According to DE 33 05 504 C2, such a groove can also be provided along the inner circumference of the toothed belt / conveyor belt.
    Such toothed belt drives often reach a considerable length. The longer such a conveyor belt is to be provided between the drive roller and a deflection roller, the greater the risk that the conveyor belt will “sag”. In order to prevent such "sagging", as is known, support rollers are provided between the drive roller and the deflection roller, which support the conveyor belt.
    The invention is based on the object of providing a toothed belt drive and an arrangement of toothed belt drives that reduce the operating noise during operation with high stability.
    This object is achieved by the toothed belt drive according to claim 1. Advantageous embodiments are mentioned in the subclaims.
    According to a first aspect of the invention, a toothed belt drive is provided for transport in a manufacturing and / or packaging process, comprising: a drive roller with a toothing running along its outer circumference, a conveyor belt that has a toothing along its inside and is driven by the drive roller, the conveyor belt having one or more continuous grooves in the toothing parallel to its direction of rotation.
    The essence of the invention is that one or more support rollers are provided, which have one or more support disks with a larger radius, these support disks rest on the inside of the conveyor belt and thus virtually designed as counterparts to the grooves of the conveyor belt are. The support disks are thus arranged in such a way that they rest on the bottom of the grooves as radial elevations of the support rollers. In particular, the support disks are designed as elevations on the respective support roller. In this sense, the support roller is formed in one piece together with the support disks and both rotate together as a functional unit.
    The inventive design, the noise is significantly reduced, since the support rollers neither air is displaced nor the teeth of the conveyor belt strikes the circumference of the support rollers. The conveyor belt is thus virtually only "carried" smoothly by the support disks.
    Measurements have shown that the noise level can be reduced by 10-15 dB. Another advantage is that the lateral guidance of the conveyor belt is taken over by the grooves and flanges can therefore be dispensed with, so that the lateral wear of the conveyor belt is reduced. This also minimizes the risk that foreign bodies contaminating the product can get onto the conveyor belt. Another positive consequence is a reduction in costs, since the production of support rollers without teeth is considerably cheaper.
    The conveyor belt preferably revolves around the drive roller and a non-driven deflection roller, the support rollers being arranged between the two rollers. This makes it possible to provide a conveyor belt with a toothed belt drive with a flexible length in which the conveyor belt rotates endlessly around the drive roller.
    In another variant, the deflection roller is designed as a drive roller. Sometimes it is necessary to drive the conveyor belt using two rollers in order to distribute the load evenly. However, if the focus is on reducing the noise level, the deflection roller, like the support roller, can be designed with support disks.
    Advantageously, the height of the elevations formed by the support disks is at least as high as the depth of the grooves. This has the effect that the toothing of the conveyor belt does not hit the circumference of the support roller. The higher the elevations are compared to the depth of the grooves, the lower the risk that the teeth of the conveyor belt will hit the support roller.
    The circumference of the elevation is expediently flat. This ensures that the support disks roll on the floor / bottom of the grooves as efficiently and gently as possible.
    The support rollers preferably act on the conveyor belt by means of a spring. By selecting the spring accordingly, the pressure on the conveyor belt can be varied, changed and adapted to the product to be transported in a targeted manner. Springs are provided in particular in the case of a vertical conveyor belt guiding direction. If the conveyor belt guidance direction runs horizontally, ie "lying down", the springs can be dispensed with.
    According to a second aspect of the invention, an arrangement is specified which comprises two toothed belt drives according to the invention with the features explained above, the first toothed belt drive spaced apart from, esp
    special above or next to the second toothed belt drive is arranged. As a result, the conveyor belts of the first and second toothed belt drives form a transport channel through which the product is transported. For example, it is possible to transport the product through the transport channel and exert a defined force on the product by means of the support rollers. So it is not only a transport, but also a processing option is provided. These processing options include, for example, embossing or shaping on one or both sides.
    Alternatively, an arrangement can also be provided in which the toothed belt drive according to the invention is arranged at a distance from a conventional toothed belt drive. In this case, the noise reduction is smaller than in the case of two toothed belt drives according to the invention, but this arrangement still represents a reduction in noise pollution.
    In an advantageous embodiment, the support rollers of the first toothed belt drive and the second toothed belt drive are arranged offset from one another in the direction of rotation. In particular when transporting a pasty food mass, such as cheese, it follows from this that the food mass meanders through a wavy course, so to speak. This staggered arrangement gives the conveyor belt more friction. Alternatively, support rollers can also be provided opposite one another - especially if less friction is sufficient for the conveyor belt.
    According to a third aspect of the invention, a use of the support disks for guiding the conveyor belt is specified. For this purpose, the support disks are aligned parallel to the direction of rotation of the conveyor belt and their elevations engage in the grooves of the conveyor belt. As a result, the conveyor belt is restricted in its freedom of movement perpendicular to the direction of rotation and, as it were, guided by the support disks parallel to their alignment. This advantageously makes it possible to dispense with so-called flanged disks, which are conventionally used to guide the conveyor belt, as a result of which the load on the side surfaces of the conveyor belt is largely reduced. This also results in a reduction in the risk of foreign bodies which otherwise arises from the fact that the flanged wheel can detach material from the conveyor belt. This advantageously results in a longer service life of the toothed belt drive.
    According to a fourth aspect of the invention, toothed belt drive for transport in a manufacturing and / or packaging process is specified comprising
    at least one drive roller with teeth running along its outer circumference,
    at least one conveyor belt which has a toothing along its inside and is driven by the drive roller, the conveyor belt having one or more continuous grooves in the toothing parallel to its direction of rotation,
    at least one deflection roller, wherein the conveyor belt revolves around the deflection roller, wherein
    the at least one deflection roller has one or more radially protruding support disks as elevations along its axis, which rest in a force-exerting manner on the inside of the conveyor belt, the elevations being designed as counterparts to the grooves of the conveyor belt and that the carrier disks are arranged so that the elevations on rest on the bottom of the grooves.
    In an advantageous manner, this significantly reduces the noise, since neither air is displaced during the operation of the deflection roller nor the toothing of the conveyor belt strikes the circumference of the deflection roller. The conveyor belt is thus virtually only "carried" smoothly by the support disks of the deflection roller. Support rollers are expediently only used in a toothed belt drive if the toothed belt drive extends over a certain length and / or if a heavy load has to be transported that the toothed belt drive according to the fourth aspect of the invention can be used both with and without support rollers.
    According to a fifth aspect of the invention, toothed belt drive for transport in a manufacturing and / or packaging process is specified comprising
    at least one drive roller with teeth running along its outer circumference,
    at least one conveyor belt which has a toothing along its inside and is driven by the drive roller, the conveyor belt having one or more continuous grooves in the toothing parallel to its direction of rotation,
    at least one deflection roller, wherein the conveyor belt revolves around the deflection roller, wherein
    the at least one drive roller has one or more radially protruding support disks along its axis as elevations,
    which rest against the inside of the conveyor belt in a force-exerting manner, the elevations being designed as counterparts to the grooves of the conveyor belt and the support disks being arranged so that the elevations rest on the bottom of the grooves.
    In an advantageous manner, this significantly reduces the noise, since neither air is displaced during the operation of the drive roller, nor does the toothing of the conveyor belt strike the periphery of the drive roller. The conveyor belt is virtually only "carried" smoothly by the support disks of the drive roller. To simplify the production of a drive roller with support disks, it is possible to cast such a drive roller, preferably from a plastic material, or to produce it in a 3-D printer.
    The support disks preferably protrude beyond the teeth of the drive roller. This offers the advantage that the support disks of the drive roller can rest on the bottom of the grooves while the toothing is effective at the same time
    can be maintained in the toothing of the conveyor belt. In this case, the radius of the support disks must not be selected too large, not that the case occurs in which the two toothings can no longer mesh with one another.
    The support rollers with support disks, the deflection roller with support disks and / or the drive roller with support disks can be combined with one another in any way in order to reduce the noise reduction effect of the gear drive.
    In the following, numerous features of the present invention are explained in detail on the basis of preferred embodiments. The present disclosure is not limited to the specifically mentioned combinations of features. Rather, the features mentioned here can be combined as desired to form embodiments according to the invention, unless this is expressly excluded below.

    packaging process comprising two toothed belt drives.
    Fig. 2 shows a conveyor belt according to the invention.
    Fig. 3 shows in a detailed view an interaction between support rollers and the conveyor belt.

    Fig. 1 shows the inventive arrangement 1 for transport in a manufacturing and / or a packaging process comprising two toothed belt drives 5A, 5B. Both toothed belt drives 5A, 5B are each rotated by a conveyor belt 10A, 10B. The conveyor belts 10A, 10B each endlessly revolve around a drive roller 15A, 15B and a deflection roller 20A, 20B. The drive rollers 15A, 15B are driven by a motor and each have a toothing 16A, 16B which is in an operative connection with the corresponding toothing 11A, 11B of the conveyor belts 10A, 10B. It follows from this that the conveyor belts 10A, 10B move in the transport direction when the drive rollers 15A, 15B rotate.
    Between the respective drive rollers 15A, 15B and the deflection rollers 20A, 20B a plurality, for example eight, support rollers 25A, 25B made of stainless steel or plastic or aluminum are provided, which support or force the conveyor belts 10A, 10B. The application of force is realized in that spring elements 30A are provided on one of the toothed belt drives, in this case the toothed belt drives 5A, which exert a force perpendicular to the direction of rotation of the conveyor belts 10A, 10B on the support rollers 25A, 25B. The number and the positioning of the spring elements 30A can be designed to be variable and thereby optimally adapted to the desired conditions. In order to prevent the conveyor belts from sagging, the support rollers 25A, 25B of each toothed belt drive 5A, 5B are arranged directly adjacent in the direction of rotation in the direction of transport. The toothed belt drive 5A is provided at a distance from the toothed belt drive 5B, so that the conveyor belts 10A, 10B here form a transport shaft 40 and their surfaces face each other directly. A pasty, malleable food mass, such as cheese, can be guided through this transport shaft 40 and simultaneously shaped. In Fig. 1, the radially protruding support disks 26A, 26B of the support rollers 25A, 25B can be seen. The support disks 26A, 26B are provided as radial elevations of the support rollers 25A, 25B and, together with the support rollers 25A, 25B, form an integral unit. The way in which these carrying letters 26A, 26B lead to a noise reduction of the toothed belt drive or the arrangement is shown in detail in the following figures.
    Fig. 2 shows a free-standing conveyor belt 10 in a perspective view, so that its structure can be seen better. It can be seen that the toothing 11 is penetrated by a continuously straight groove 12. Here, the groove 12 runs along the transport direction / circumferential direction. In FIG. 2, four grooves 12 are made in the toothing 11 for this purpose, the number being freely selectable in principle. The greater the number of grooves 12, the more uniformly a force can be transmitted to the conveyor belt 10 via the support disks 26, as will be shown below. The grooves 12 have a defined depth and have a flat bottom. A wall of the grooves can diverge over this base, for example in a straight line or in a V-shape. The V-shaped tapering shape can facilitate centering when inserting the support disk, while on the other hand the straight wall can be produced more cost-effectively.
    Fig. 3 shows a detailed view of how the support disk 26 of the support rollers 25 rests on the bottom of the groove 12 and rolls on this. The fact that the height of the elevation of the support disk 26 is at least as high as the recess of the groove 12 prevents the toothing 11 from striking the circumference of the support rollers 25. Measurements have shown that this can reduce the noise level by 10-15 dB. In order to ensure this also for a plurality of support rollers 25, the support rollers must be arranged in alignment one behind the other so that their respective support disk 26 can be received in the straight groove 12.
    The toothed belt drives 5A, 5B from FIG. 1 can also be designed alternatively in order to reduce noise and to increase the lateral stability of the guidance of the conveyor belt.
