    Technical area
    The present invention relates to a transport system with a magnetic conveyor belt, in particular set up for vibration-free and contactless transport of sensitive goods, such as chemicals, bottled gases, explosives and the like.
    State of the art
    In conventional conveyor belts, the conveyed material is placed on a conveyor belt, e.g. cell chain, plastic belt, magnetic belt, etc., and transported by the movement of the conveyor belt and the resulting static friction between the conveyed material and the conveyor belt. These moving conveyor belts and cell chains are open, get dirty very easily and are therefore difficult to clean.
    For conveying magnetic workpieces or magnetic carriers, in particular magnetic conveyor belts are known. The use of so-called contactless magnetic conveyor belts, which in particular avoid laborious cleaning of the conveyor belt, is also known for transporting dangerous substances, which are, for example, carcinogenic, toxic, flammable, etc.
    From US Pat. No. 6,571,934 A, a conveying device for sample containers which can be received in a carrier is known, the carrier being transported along a static conveying surface. For this purpose, a magnetic element is received on a lower surface of the carrier, which can be brought into interaction with a permanent magnet. This permanent magnet is arranged on a conveyor belt below the conveying surface and can be moved parallel to the conveying surface by means of the conveyor belt. However, the carrier and the magnetic element must be adapted to the sample containers to be transported in a vibration-free manner.
    Summary of the invention
    The object of the present invention is to provide a transport system for transporting goods to be conveyed or transported by means of a conveyor belt, whereby a complex and sometimes dangerous cleaning of the conveyor belt is largely avoided and at the same time a vibration-free movement of the transported goods is made possible. The transport system should also be set up to transport a wide variety of objects and to provide a variety of movement options. In addition, the transport system should be expandable or combinable.
    These objects are achieved in particular by a transport system according to claim 1.
    A transport system according to the invention which is suitable for conveying or transporting a large number of different objects universally and without contact includes in particular a static transport or conveying surface along which the objects are moved in a conveying direction. This conveying surface, which is in direct contact with the conveyed goods to be transported, is designed to be easy to clean and / or disinfect and has good sliding properties with respect to the objects to be transported.
    The invention is based on the principle of contactless conveyance by means of a conveyor belt equipped with transport magnets. The transport system according to the invention accordingly comprises a magnetic conveyor belt on which at least one transport magnet can be arranged. The magnetic conveyor belt is moved in one direction by means of a drive unit. In particular, the magnetic conveyor belt can be designed as a belt which circulates endlessly around a pair of belt pulleys, one of the belt pulleys being set in rotation, for example, by a bidirectional motor. At least one transport magnet can be arranged on the magnetic conveyor belt, preferably several transport magnets arranged one behind the other, which are, for example, firmly connected to the conveyor belt by means of suitable connection technology. Alternatively or additionally, several transport magnets can also be provided next to one another. The number and the arrangement as well as the distance between the transport magnets, especially in the conveying direction, can vary individually depending on the transported goods and requirements.
    Furthermore, the inventive transport system comprises a conveying surface, for example designed as a rigid plate, which is at least partially arranged above the magnetic conveyor belt without contact with it and on which the goods to be transported or the objects to be transported can be arranged. The transport system according to the invention is set up to move the transported goods by means of a magnetic interaction between the moving transport magnet and a conveying element along a transport direction, the conveying element being positionable on the conveying surface. The transport magnet and conveyor element are not in direct contact. Rather, with the approach of the transport magnet to the conveyor element, which exhibits magnetic properties, caused by the movement of the magnetic conveyor belt, it is moved along with the transport magnet moved in the direction of transport by means of magnetic force. In this case, the moving conveyor element can take along a conveyed item located on the conveying surface in the conveying direction. When the transport magnet approaches the conveyor magnet, the conveying surface formed as a plate between them is clamped. So that the conveying element can be moved along the conveying surface, the transport magnet and the conveying magnet can be provided with a coating that has good sliding properties, e.g. a Teflon layer.
    The transport system according to the invention is provided in particular for transporting or conveying different goods to be transported. Accordingly, the contactless conveyance is not only limited to magnetic objects, but is suitable for conveying different forms of transport goods, in particular also those which do not show any magnetic properties. This is advantageous when conveying dangerous transport goods, whereby the transport goods can be placed on the conveying surface and safely transported along it, which is rigid, clean, smooth and easy to clean and in particular has no grooves, grooves, holes and / or slots and is also airtight.
    In one embodiment, at least one conveying magnet can be received on the conveying element, which magnet can be positioned on the conveying surface and can be moved along the conveying direction by means of the magnetic interaction with the transport magnets.
    The conveying element can be designed in the form of a carrier in which the goods to be transported can be received. For example, such a carrier can be designed as a magnetic frame in which one or more containers are held. The frame can include the conveyor magnet in the form of a ferromagnetic plate received in a closed cavity.
    In one embodiment of the transport system, the conveying element is designed in the form of a driver, on which at least one conveying magnet can be received, in particular on the underside. The conveying element can be positioned on the conveying surface behind the goods to be conveyed, as seen in the direction of conveyance, and moves them along the conveying surface. The conveying element designed as a driver can have an elongated shape in the form of a bar, which preferably extends over at least part of the width of the conveying surface and has a certain height. The conveying element is preferably placed on the conveying surface transversely to the direction of conveyance and, viewed in this direction, behind the goods to be conveyed. The conveying element is accordingly designed in the form of a conveying slide. The shape of the conveying element can be adapted to the shape of the goods to be transported, so that they can be safely moved or displaced without vibrations by means of the conveying element along the conveying surface.
    In one embodiment of the transport system according to the invention it is provided that the magnetic interaction between the transport magnet and the conveyor magnet is sufficiently high to overcome resistance forces between the goods to be transported and / or the conveyor element and the conveying surface. When the movable transport magnet approaches the conveying element and the magnetic forces emanating from it overcome the frictional resistance between the conveying element and the conveying surface, the conveying element is moved along the conveying surface in the transport direction. If the resistance forces between the goods to be transported and the conveying surface have also been overcome, the conveyor element moves or pushes the goods to be transported when they come into contact with them along the direction of transport on the conveying surface. Abrupt movements of the goods to be transported, which can for example be an open container filled with a substance, are avoided since the at least one transport magnet secures the conveying element and moves it continuously and uniformly along the conveying surface, while the transport magnet is moved at a constant speed.
    In a further embodiment of the transport system according to the invention, the number and / or strength of the conveying magnet or magnets that can be received on the conveying element can be matched to the weight of the conveyed goods and of the conveying element in order to counteract resistance forces between the conveyed goods and the conveying element on the one hand and the conveying surface on the other overcome.
    In one embodiment of the transport system according to the invention, a plurality of mutually spaced transport magnets are arranged on the magnetic conveyor belt, seen in the transport direction, which divide the magnetic conveyor belt into sections or segments. The dimensions of the sections or segments between adjacent transport magnets can be matched to the goods to be transported. Furthermore, several transport magnets can be arranged over a width of the magnetic conveyor belt.
    In another embodiment of the transport system according to the invention, the conveying surface has a reduced-friction surface. In particular, the conveying surface is a static surface with a smooth, clean and easy-to-clean surface, which can in particular be provided with a low-friction coating. With regard to the frictional resistance and the cleaning properties, a Teflon layer has proven to be advantageous, which can be applied according to known methods.
    In yet another embodiment of the transport system according to the invention, the drive unit of the magnetic conveyor belt is bidirectional. In particular, the magnetic conveyor belt can be moved forward and backward by means of a belt drive mechanism.
    According to a further embodiment of the transport system according to the invention, the goods to be transported can be open containers which are filled with a substance. This substance can be a liquid or powder or the like, which, if this is necessary due to a hazard to the environment, can be filled into the open container in a preferably largely closed chamber. In particular, such a filling station can be combined with the transport system according to the invention. In particular, the transport system is suitable for conveying dangerous goods to be transported, for example if they are poisonous, carcinogenic, flammable and / or explosive substances that are to be conveyed largely without vibrations. The transport system can therefore also be combined, at least in sections, with a cover that represents a kind of protective chamber.
    Brief description of the drawings
    [0020] Embodiments of the invention are explained in more detail below by way of example with reference to the accompanying drawing. It shows: FIG. 1 a perspective view of a transport system with a cover; FIG. 2 shows a perspective view of the transport system with the conveyor elements placed thereon; FIG. 3, in a broken representation, a magnetic conveyor belt equipped with transport magnets and a conveying surface arranged above it in a perspective view; FIG. 4 shows a longitudinal section through the transport system according to one embodiment; and FIG. 5 shows a cross section through the transport system according to one embodiment.
    Detailed description of the embodiments
    FIG. 1 shows a perspective view of a transport system 1 according to the invention in a first embodiment. The transport system 1 in the embodiment shown has a conveying surface 10, along which a transport item (not shown) to be positioned thereon can be transported in a transport direction, indicated by arrow 12. Also indicated is a cover 2 which provides a kind of protective space for the goods to be transported. A drive unit 20 is indicated on one side, which moves a conveyor belt 16 (not shown) by means of a drive mechanism along the transport direction 12 and / or in the opposite direction.
    In Figure 2, the transport system 1 is shown without the cover 2. Several conveying elements 14 are shown on the smooth conveying surface 10, which in particular provides good sliding properties. These conveying elements 14 can simply be placed on the conveying surface 10, in particular behind a conveyed item as seen in the direction of conveyance 12. The conveying element 14 can accommodate at least one conveying magnet (not shown) or it can itself be made of a magnetic material. In the illustration of FIG. 2 it can be seen that the conveying surface 10 has a certain width 11 and along at least part of the conveying surface 10 an upwardly protruding edge is provided, which represents a kind of boundary.
    In Figure 3, the conveyor surface 10 is partially broken open to give a view of the conveyor belt 16 below. The conveyor belt 16 can also be referred to as a magnetic conveyor belt. It comprises a multiplicity of transport magnets 18 at regular or irregular intervals along the transport direction 12. In particular, transport magnets 18 are arranged over almost the entire width of the conveyor belt 16. A plurality of transport magnets 18 can preferably be arranged on the conveyor belt 16, which magnets can be arranged one behind the other, in particular at a definable distance from one another, as seen in the transport direction 12, and next to one another, viewed transversely to the transport direction 12. Furthermore, a drive mechanism of the conveyor belt 16 is shown in FIG. 3, comprising the drive unit 20 and conveyor rollers 22 and 24.
    FIG. 4 shows a longitudinal section through part of the transport system 1. Several conveyor elements 14 lie on the conveyor surface 10 and are in magnetic interaction with the transport magnets 18, which in turn are arranged on the conveyor belt 16 below the conveyor surface 10. The conveyor belt 16 can, for example, be an endless belt, ie a closed belt, in particular a toothed belt, which is guided over the at least two conveyor rollers 22, 24, e.g. a so-called passive roller or deflection roller 22 and a drive roller 24, which is connected to the drive unit 20 for active driving of the conveyor belt 16 is connected. Roller 22 and drive roller 24 are each rotatably mounted, for example, in lateral pivot bearings which can be received in a lateral frame of the transport system 1. In order to be able to tension the conveyor belt 16, the corresponding pivot bearings for at least one of the rollers 22, 24 can be designed in such a way that they can be adjusted along the side frame by means of an adjustment device in order to be able to adjust the distance between the rollers 22, 24.
    When one of the transport magnets 18 approaches the conveyor element 14, due to the magnetic interaction between the transport magnet 18 and the conveyor element 14, or a conveyor magnet 15 accommodated therein, it is carried along after overcoming frictional forces along the transport direction 12, as is a transport item ( not shown), which is displaced along the conveying surface 10 by means of the moving conveying element 14.
    In Figure 5, a cross section through the transport system 1 is shown. The conveying surface 10 is received in a trough-like frame 30, which, for example, also extends at least partially over the upwardly extending edge. The cover 2 is also indicated. The conveying element 14 is placed on the conveying surface 10 and extends largely over the width 11 of the conveying surface 10. In the embodiment shown, a plurality of conveyor magnets 15 are accommodated on the conveyor element 14, the number and / or the strength of the conveyor magnets 15 being adaptable to the circumstances.
    The conveyor belt 16, on which a multiplicity of transport magnets 18 are arranged, runs below the conveying surface 10. The drive mechanism with the drive unit 20 and the conveyor rollers 22, 24 is indicated. The contactless magnetic conveyor belt 16 makes it possible for goods to be transported to slide on the conveyor surface 10 with great care and largely free of vibrations.
