    DESCRIPTION Conveyor for conveying products
    The present invention relates to a conveying device for conveying products, comprising a conveying means extending along a conveyor path having at least one curve, a motor driving the conveying means and a plurality of product carriers which are attached to the conveying means one behind the other in conveying direction and respectively for receiving a conveyor designed to be conveyed product. Furthermore, the invention relates to a coating system with such a conveyor, a method for conveying products using a conveyor and a method for converting an existing conveyor. Conveyors of the type mentioned are known in the art in a variety of configurations. They are typically used to move products from one processing station to another within a production or assembly line. For example, conveyors may be part of a rim coater in which the rims are washed, dried, powder coated and fired in a furnace at a different station. Thus, DE 10 2007 010 312 A1 discloses a conveyor for conveying rims in the form of a so-called floor conveyor. The bottom conveyor comprises a conveying means in the form of an endless chain, which extends along a defined conveying path, a motor driving the conveyor and a plurality of product carriers, which are fastened in succession to the conveyor in the conveying direction, each having a spindle-like design and at their free end are provided with a trained for receiving a rim product receptacle.
    The distance between the individual product carriers of such conveyors is normally chosen as low as possible in order to achieve a maximum conveying capacity. When selecting the distance, however, care must be taken to ensure that it is sufficiently large that the products received on the adjacent product carriers do not collide in curved areas of the conveying path in which the distance between adjacent product carriers and straight areas is reduced. Against this background, the narrowest curve of a conveying path always represents a factor limiting the conveying capacity of the conveying device.
    When with a conveyor in which the distance between adjacent product carriers relative to products having specific outer dimensions, such as 19 inch rims, is optimized for maximum conveying capacity, products with larger outer dimensions, such as 21, should additionally be conveyed Inch rims, so for the larger products usually no good conveying capacity can be achieved because the larger products would collide, at least in the curved areas of the conveyor. For example, when transporting 21-inch rims in practice, rim manufacturers release every second product carrier in order to prevent a collision of the rims in curved areas of the conveying path. An alternative approach to avoiding a collision is to increase the existing distance between adjacent product carriers to improve the conveying capacity of 21-inch rims so that a collision of the rims in the curved areas of the conveying path is reliably prevented, even if with the conveyor 21 inch rims are transported. However, this measure is inevitably accompanied by a reduction in the capacity of 19-inch wheels.
    Of course, analogous problems also arise when transporting other products, as soon as at least two product types are to be transported with a conveyor, which have different sized outer dimensions.
    Based on this prior art, it is an object of the present invention to provide a conveyor of the type mentioned, a coating system with such a conveyor, a method for conveying products and a method for converting an existing conveyor, with which the previously described Problems are at least partially eliminated at low cost.
    To achieve this object, the present invention provides a conveyor of the type mentioned, which is characterized in that a plurality of product carrier, in particular only every second or all product carrier, a fixed to the conveyor base and a relative to the base is part movable, a product intake on at least a first positioning means provided product receiving part / include that along the conveying path in the region of the curve at least a second positioning means is provided, and that the first positioning means and the at least one second positioning means are formed and cooperate such that the positions of the Product receiving parts relative to the position of the associated base parts is changed by a predetermined amount as soon as the first positioning means come into or out of engagement with the at least one second positioning means. In other words, the present invention proposes a conveyor in which at least some product carriers are designed such that the products held by them are moved relative to products held directly adjacent to product carriers in the curved areas of the conveying path in such a way that a collision occurs despite a narrow path Distance between the individual product carriers can be safely avoided, whereby an optimal conveying capacity is achieved. In principle, it is possible to move adjacent products vertically and / or horizontally relative to one another by a degree which prevents collision.
    Preferably, the conveyor is an endless chain or an endless belt. In this way, a very simple construction of the conveyor is achieved.
    Advantageously, the conveyor is guided in a first guide of a rail profile, whereby a safe operation of the conveyor is ensured.
    According to an embodiment of the present. Invention guide rollers are provided on the product carriers, which are guided a second guide of a rail profile. In this way, a trouble-free movement of the product carrier along the conveying path can be ensured.
    Advantageously, the first positioning means and the at least one second positioning means are designed such that they act purely mechanically together. Accordingly, can be dispensed with expensive and expensive electrical, pneumatic or hydraulic additional components.
    A preferred embodiment of the conveyor according to the invention is characterized in that the base parts are attached to the conveyor, that the product receiving parts are each guided vertically relative to the associated base part guided, and that the second positioning means by a along the curve extending at the free ends with an upwardly facing ramp and a downwardly facing ramp provided guide rail is formed on which the first positioning support. In this way, a lifting device is provided by simple means, with the help of which adjacently arranged products are displaced vertically in curves of the conveying path to each other.
    Preferably, the base part and the product receiving part each engage telescopically, whereby a simple construction is achieved.
    Advantageously, the base parts are each provided with a slot or a groove, wherein the product receiving parts each have a projection received in the slot or in the groove, or vice versa. This provides guidance of the product receiving part during the upward or downward movement. Preferably, the slots or the grooves extend straight in the vertical direction. Thus, a rotational movement of the product receiving parts during an upward and downward movement is prevented. Alternatively, however, the slot or groove may also have curvatures to effect selective rotational movement during raising and lowering of the product receiving members, in view of the external shape of the products to be conveyed.
    The first positioning means are preferably designed as lifting rollers pointing in the conveying direction. Thanks to such lifting rollers, the friction between the first positioning means and the at least one second positioning means is reduced.
    Advantageously, the product receiving parts are each provided with two oppositely arranged first positioning means which are each guided on a second positioning means in the form of a guide rail extending along the curve and provided at the free ends with an upwardly facing ramp and a downwardly facing ramp the guide rails extend parallel to each other and receive the product receiving parts between them. In this way, a very robust construction is achieved
    To achieve the object mentioned above, the present invention further provides a coating system for coating products, which has at least one inventive conveyor of the type described above.
    To achieve the object mentioned above, the present invention further provides a method for conveying products using a stationary conveyor, in particular using a conveyor according to the invention of the type described above or one which is part of a coating system according to the invention, in which the products Product carriers are moved along a predetermined, at least one curve having conveying path, characterized in that immediately adjacent products are moved in the region of the curve using suitably trained position means relative to each other so that a distance-related collision of these products in the region of the curve is prevented, ie a collision that would inevitably occur without such relative movement due to a distance selected between the product carriers.
    Preferably, every second product is raised or lowered in the region of the curve.
    According to one embodiment of the method according to the invention, the products are rims.
    Further, the present invention provides a method for converting the above-mentioned object, a method for retrofitting an existing conveyor for conveying products, wherein the existing conveyor means, which extends along a at least one curve having conveying path, a conveyor driving the motor and a plurality of Has product carriers, which in the conveying direction one behind the other attached to the conveyor and each designed to receive a product to be conveyed, characterized in that a plurality of product carriers, in particular every second product carrier is replaced by such a product carrier / is attached to the conveyor base part and a product receiving part which is movable relative to the base part and has a product and at least provided with a first positioning means, which has at least one second position along the conveying path in the region of the curve is provided, wherein the first. Positioning means and the at least one second positioning means are formed and cooperate such that the position of the product receiving parts relative to the position of the associated base parts is changed by a predetermined amount as soon as the first positioning means come into or out of engagement with the at least one second positioning means. It should be understood that the new product carriers that replace the existing product carriers, as well as the second positioning means, may be configured as previously described with reference to the inventive conveyor.

    The figures show a conveyor 1 according to an embodiment of the present invention, which forms part of a coating system and serves to transport products 2, here in the form of rims, from one processing station to the next. The conveyor 1 comprises a conveying means 3 in the form of an endless chain which extends along the conveying path of the conveyor 1, is guided within a first guide 4 of a rail profile 5 extending along the conveying path and is driven in a known manner by a motor (not shown). As an alternative to an endless chain, the conveying means 3 may also be formed by an endless belt, an endless rope or the like, to name just a few examples. Furthermore, the conveyor 1 comprises a plurality of first product carriers 6a and second product carriers 6b, which are alternately and successively fixed in the conveying direction on the conveyor 3 at regular intervals and are each designed to receive a product to be conveyed.
    The first product carriers Sa, as shown in particular in FIG. 6, in each case, viewed from below upwards, comprise a vertically arranged base plate 7, the lower region of which is screwed to a chain link of the conveying means 3 which is not shown here. In this lower area 7 side plates 8 are fixed on both sides of the base plate by means of dowel pins 9, which compensate for a game between the chain link and the base plate 7. Further, through-holes 10 are provided in the lower region through which extend corresponding, also not shown fastening screws. At the top of the base plate 7, two guide rollers 11 are fixed, which are rotatable about axes extending in the vertical direction 12 and aligned with each other in the conveying direction. The guide rollers 11 are guided in a second guide 13, which is defined by another extending in the conveying direction rail profile 14. On the base plate 7, a one-piece and vertically extending spindle 15 is held. Ara upper free end of the spindle is a Produktauf measure 16 is provided, which is designed to receive products to be conveyed 2. A description of the exact design of the product holder 16 is omitted here, since it is not relevant to the present invention. In short, a transportable can be easily slipped over the product receptacle 16, so that the rim axis is arranged vertically.
    The second product carrier 6b include, as shown in Figures 6 to 11, analogous to the first product carriers 6a a vertically arranged base plate 7, side plates 8, through holes 10 and guide rollers 11. On the base plate 7 is also a vertically extending spindle 15 is held, however, which is somewhat shorter and formed with a smaller diameter than the spindle 15 of the product carrier 6a. The base plate 7, which held on this components and the spindle 15 together form a base part A. About the spindle 15 loosely a tube 17 is slipped so that it is movable relative to the spindle 15 in the vertical direction. On the tube 17, starting from the lower free end, a vertical slot 18 is formed, through which a projection 19 fastened to the spindle 15 extends, so that a rotation of the spindle 15 and tube 17 is prevented in the context of the aforementioned vertical movement. In the lower region of the tube 17 first positioning means 20 are provided in the form of oppositely arranged lifting rollers, which are rotatable about a horizontal axis and point in the conveying direction. At the upper free end of the tube 17, a product receptacle 16 is provided analogously to the first product carriers 6 a, which is designed to receive the products 2 to be conveyed. The tube 17 and the product receptacle 16 together form a product receiving part B.
    Along the conveying path, second positioning means 21 are provided in those areas in which the conveying path describes a curve. The second positioning means 21 are presently formed by two guide rails 22 which are arranged at the top of the guide rollers 11 receiving rail nenprofils 14 at the same height level, extending parallel to each other and provided at their free ends with an upwardly and downwardly facing ramp 23 are. During operation of the conveyor 1, all product receptacles 15 of the first and second product carriers 6a and 6b are at the same height level in straight regions of the conveying path. The first positioning means 20 roll on the top of the rail profile 14. As soon as a second product carrier 6b at the end of a straight region of the conveying path reaches the second positioning means 21 arranged at the beginning of a curve region, the first positioning means 20 arranged on the tube 17 of the second product carrier 6b engage with the ramps 23 of the second positioning means 21 it is shown in FIG. If the second product carrier 6b is then moved further in the conveying direction, the first positioning means 20 are moved upwards along the ramps 23, whereby the tube 17 is pushed upwards relative to the spindle 15 and the product receptacle 16 held on the tube 17 is lifted together with the corresponding product 2 becomes. The extent to which lifting of the product receptacle 16 takes place is determined by the height difference h between the upper side of the rail profile 14 and the upper side of the guide rail 22 of the second positioning means 20. In this way, the product 2 held on the second product carrier 6b is staggered in height with respect to the products 2 held on the two adjacent first product carriers 6a, so that the products 2 are pushed into each other and overlap each other without overlapping to collide. Accordingly, it is possible to arrange the product carriers 6a and 6b in each case at a very small distance from each other, without any danger of collision. It is also possible with the conveyor 1, for example, both 19-inch wheels and 21-inch wheels to transport, without this having serious effects on the production capacity of the respective product types. In the height-offset arrangement, the products 2 pass through the curve area of the conveying path, whereupon they are brought back to the same height level at the end of the curve when they reach the downwardly facing ramp.
    It should be pointed out that existing conveying devices 1 for conveying products which have exclusively product carriers 6a can easily be converted to realize the basic idea according to the invention by replacing a multiplicity of product carriers 6a, in particular every second product carrier 6a by a product carrier 6b and along the conveying path in the region of the curves second positioning means 21 are provided. In this way, the delivery capacity of an existing conveyor can be easily, inexpensively and easily optimize.
    It should be understood that the scope of the present invention is not limited to the embodiment described above. Rather, changes and modifications are possible without departing from the scope defined by the appended claims. Thus, the conveyor need not necessarily be a floor conveyor, just to give an example. Also, in curved areas of the conveying path instead of or in addition to a lifting movement and a horizontal
    Sideways movement and / or rotational movement of the products (2) are initiated, if this makes sense taking into account the external dimensions of the subsidized products.
