    15 20 25 30 35 PG20003SE00 unit forms a pivot center for the subsequent plastic link. Rotational movements are transmitted only via the ball. The task of the stick is only to fix and rotate the ball.
    The disadvantage of a pin centrally fixed in the ball is that the force transfer from the ball to the subsequent link will be strongly centered to the nose portion of the link and the ball, i.e. the part of the ball which is at the front in the transport direction. A further disadvantage is that great demands are made on the pin to be so firmly anchored that relative movement to the ball, both radially and axially, cannot occur. This means that the pin requires both great assembly force and also, when servicing the customer, great disassembly force. Most often, special tools are not available at the customer. A further disadvantage is that assembly and disassembly of the ball is difficult as this takes place from the side of the link and results in an opening which is larger than the ball diameter, which weakens the tensile strength.
    The summary of the Swedish patent no. SE 511 811 describes a plastic chain constructed according to the ball link principle and which comprises a ball and a pin made as an element in steel. The disadvantages of a ball integrated into the ball are that it is expensive to manufacture, the wear between the steel ball and the subsequent plastic link is relatively high and the concentration of force from the ball to the subsequent link will be strongly concentrated to the nose and ball nose portions when the plastic chain is in use. The plastic material around the pin can thus be deformed during use, which can create unwanted play between the components of the transport chain, which in turn can reduce the life of the plastic chain and create noise.
    SUMMARY OF THE INVENTION An object of the present invention is to provide an improved transport chain for transporting objects, i.e. products and / or materials, along a transport path in a transport direction.
    This object is achieved by a transport chain, which comprises a plurality, i.e. two, three, four or more chain links, which are connected by means of a hinge segment between each individual chain link, which hinge segment comprises a bearing element. Each chain link comprises a recess which is arranged to receive said bearing elements.
    The bearing member is substantially spherical and includes a plurality of through openings.
    The hinge segment also comprises a plurality of pins arranged in said through-openings, both in the hinge segment and the subsequent link. PG20003SEOO Such a so-called ball link principle transport chain thus has a hinge segment which does not comprise a centrally mounted pin, i.e. the hinge segment has no pin extending through the center of the hinge elements of the hinge segment. Thus, when the conveyor chain is in use, the power transmission from the substantially spherical bearing element to the subsequent chain link will not be strongly centered to the muzzle portion of the chain link and the substantially spherical bearing element, i.e. the part of the chain link and the part of the substantially spherical bearing element without the force will be distributed over a larger contact area. Torque absorption becomes significantly more favorable if a plurality of pins are used compared to if only one centrally mounted pin is used. The wear between the substantially spherical bearing element and the subsequent chain link will consequently be less compared with known ball joint principle transport chains with hinge segments which comprise a centrally fixed pin.
    A conveyor chain as above also provides chain links which are pivotable relative to each other about two perpendicular pivot axes each extending from the conveying direction of the conveyor chain and the hinge segment is self-adjusting to the main bearing, i.e. to the sliding surfaces between the lower part of the conveyor chain and a beam. The conveyor chain can thus be driven in a screw-like movement around its conveying direction. The pins are used to anchor the bearing element to the chain link and for force transmission and torque absorption during both horizontal and vertical rotational movement from a chain link to the bearing element and further to the subsequent link.
    The term "substantially spherical bearing element" is considered to mean a bearing element which has the shape of a sphere or of a part of a sphere, for example a sphere which lacks one or more cap surfaces, or a bearing element which has a sphere-like shape even if all points on its outer surface are not located at the same distance from the center of the bearing element.
    According to an embodiment of the invention, said plurality of pins are arranged to provide rotational safety, i.e. to provide rotational and rotational safety, to said substantially spherical bearing elements and said chain link.
    According to another embodiment of the invention, said plurality of pins are symmetrically mounted around the center of said substantially spherical bearing elements. Alternatively, said plurality of pins are asymmetrically mounted around the center of said substantially spherical bearing elements. According to a further embodiment of the invention, said plurality of pins, and consequently the openings of the substantially spherical bearing element and the chain links, are perpendicular to the conveying direction. transverse direction in relation to the extent of the transport chain.
    It should be noted that not all pins of said plurality of pins necessarily need to have the same shape, the same cross section, the same dimensions, the same extent through the substantially spherical bearing element or be made of the same material.
    According to an embodiment of the invention, said chain link comprises a separate load-bearing unit, i.e. a load-bearing surface covering at least a part of the upper side of the chain link when the transport chain is in use, which load-bearing unit is arranged to be attached to said chain link, i.e. the chain link and the load-bearing unit do not form an integrated element.
    According to another embodiment of the invention, said plurality of pins are axially locked to said chain link via said goods carrying unit, i.e. the pins cannot move along their longitudinal axis.
    According to a further embodiment of the invention, said chain link comprises a locking mechanism for locking said goods carrying unit to the chain link. The load-bearing unit may be arranged to be able to move with respect to the chain link after it has been attached to the chain link. A movable goods carrying unit can then be locked manually or automatically with such a locking mechanism when the conveyor chain is in use or when the conveyor chain is driven along a certain part of a conveyor track.
    Due to the fact that the construction of the conveyor chain according to the invention is not complicated and it is narrow compared to conveyor chains according to the gimbal principle, the size of the sliding surface of the goods carrying unit is not limited to a sliding strip.
    According to another embodiment of the invention, said plurality of pins are cylindrical.
    The cost of the transport chain can be reduced because ordinary cylindrical pins can be used. However, the pins can have any uniform or non-uniform cross-section. 10 15 20 25 30 PG20003ENO0 The pins may be wholly or partly of a metal or alloy, such as steel, plastic, composite material or any suitable material.
    According to a further embodiment of the invention, said substantially spherical bearing element comprises a muzzle at the front in said conveying direction and the surface of the muzzle is uneven / rough / rough, i.e. the surface of muzzle of the substantially spherical bearing element does not follow the spherical curvature of the substantially spherical bearing element. wavy, for example, so that there is a larger contact area or more than one contact point between the bearing element and the chain link which accommodates the bearing element when the transport chain is in use. For example, the substantially spherical bearing member may be formed by removing a cap in the muzzle and the surface of the muzzle may be made rough or wavy. Alternatively, or in addition, the surface of said substantially spherical elements has one or more depressions and / or projections.
    According to an embodiment of the invention, said chain link comprises a plurality of legs and said substantially spherical bearing elements are arranged to be inserted in said recess past the legs in a direction substantially parallel to the transport direction of said transport chain when assembling said transport chain. The transport chain is thus simple and not expensive or time-consuming to manufacture and assemble or disassemble, and no special tool is necessary during assembly or disassembly.
    According to another embodiment of the invention, said chain link comprises at least one opening arranged to receive said plurality of pins. This at least one opening can for instance be arranged in the legs of a chain link.
    According to a further embodiment of the invention, said substantially spherical bearing elements are multi-part, for example two-part.
    According to an embodiment of the invention, said substantially spherical bearing elements consist of a plurality of parts which can be pivoted relative to each other.
    The present invention also relates to a conveyor chain system comprising a conveyor track and a conveyor chain some embodiment of the invention. PGZOOOSSEOO According to an embodiment of the invention, said transport path is arranged for transporting objects along a transport path which extends in three dimensions, such as a spiral transport path.

    It should be noted that the drawing is not necessarily to scale and that the dimensions of certain details may have been exaggerated for the sake of clarity.
    DETAILED DESCRIPTION OF EMBODIMENTS Figure 1 shows a chain link 10 which is intended to be connected to a subsequent similar or identical chain link by means of a lead segment placed between the chain link 10 and a subsequent chain link. The guide segment comprises a bearing element 12 and the chain link 10 comprises a recess 14 with a substantially spherical surface arranged to receive said bearing element 12. The bearing element 12 is substantially spherical and comprises a plurality of through openings 16. The recess 14 may have a corresponding substantially spherical bearing surface for receiving PG20003SEO0 12. The hinge segment also comprises a plurality of pins 18 arranged in said 16 both in the conveyor chain are in use. The pins 18 create a rotational safety with respect to the through-opening joint segment and subsequent link when the substantially spherical bearing element 12 and the chain link 10 when the conveyor chain is in use.
    The pins 18 may be symmetrically or asymmetrically mounted around the center of the substantially spherical bearing member 12. In the illustrated embodiment, two pins are shown which extend perpendicular to the conveying direction 20 when the conveyor chain is in use.
    The chain link 10 may, for example, be wholly or partly of plastic. The pins 18 may be cylindrical steel pins. The pins 18 can, for example, be 20-100 mm long and / or have a diameter of 3-10 mm depending on the application.
    The chain link 10 comprises a separate goods carrying unit 22 which is arranged to be attached to said chain link 10. The chain link 10 may also comprise a locking mechanism (not shown), such as a hook and holding hook or velcro to at least temporarily lock said goods carrying unit 22 to the chain link 10 when transporting is in use, or when the conveyor chain is driven up or down along a spiral conveyor chain.
    The chain link 10 comprises two legs 24 in its rear part, which legs 24 are arranged at a distance from each other. The substantially spherical bearing element 12 is arranged to be inserted into the recess 14 of the chain link past the legs 24 in a direction substantially the transport chain. When the substantially spherical bearing element 12 of a subsequent parallel to the conveying direction of the conveyor chain when assembling chain link 10 has been inserted into the recess 14, the pins 18 are inserted through openings in the chain link 10 and corresponding openings 16 in the substantially spherical bearing element 12. For example, the goods carrier 22 is attached to the chain 10 and locks the pins 18 axially to the Chain Link 10.
    Figure 2 shows several different views of two adjacent links 10 of a conveyor chain 26 which have been interconnected by means of a hinge segment comprising a substantially spherical bearing element 12 and a plurality of pins 18, two pins in the illustrated embodiment.
    All, most, some or at least two chain links 10 of a conveyor chain 26 can be interconnected in this way. PG20003ENOO The chain links 10 may be U- or V-shaped or have any suitable design. In the illustrated embodiment, the chain links are V-shaped and may have an angle between the legs 24 of 30-60 °. The diameter of the substantially spherical bearing element 12 may, for example, be about 2-10 times as large as the transverse dimension of the pins 18 or more. The diameter of the substantially spherical bearing element 12 may be 10-20 mm, for example 16 mm, and the diameter of the pins 18 may be 3-6 mm, for example 4 mm.
    Figure 3 shows the substantially spherical bearing element 12 which comprises a plurality of through-openings 16, through which a plurality of pins 18 are inserted when the conveyor chain is assembled. The substantially spherical bearing element 12 may, for example, be wholly or partly of a metal or alloy, such as steel, plastic, a composite material or any other suitable material.
    The substantially spherical bearing element comprises a nose portion 28 at the front in said transport direction. A skullcap surface has been removed in the muzzle 28 and the surface at the muzzle is uneven / rough / rough, i.e. the surface of the muzzle is for example grooved or wavy. According to an embodiment of the invention, the substantially spherical bearing element 12 can be multi-part, for example two-part and consist of two separate parts 12a and 12b. According to another embodiment of the invention, the substantially spherical bearing element 12 may be constituted by a plurality of pivotable parts relative to each other, for example two parts 12a and 12b may be arranged to be pivotable around a pivot center 30. A plurality of bearing element parts 12a and 12b are thus connected to such that in the case of power transmission via the pins 18, the bearing element parts 12a and 12b will occupy a more optimal abutment surface against the contact surface of the chain link.
    Figure 4 shows a goods carrying unit 22 according to an embodiment of the invention. The goods carrier unit 22 comprises a flat surface for transporting objects along a transport path, such as a spiral transport path. On the underside of the goods carrying unit 22 there are a plurality of projecting flanges 32 which are arranged to cooperate with the sliding surfaces of a conveyor beam when the conveyor belt is in use.
    Figure 5 shows a conveyor chain system 34 comprising a conveyor chain 26 according to an embodiment of the present invention, which conveyor chain 26 is arranged to convey objects 36 from position A to B along a conveyor path in a conveying direction PGZOOOBSEOO 20. The conveyor chain system 34 comprises a support surface for the conveyor chain 26 and a drive system, such as a plurality of motor gears 38 used to drive the conveyor chain 26 in one or more conveyor directions 20. It should be noted that the conveyor direction 20 can be changed while the conveyor chain 26 is in use. Conveyor chain 26 according to the present invention can be operated at high speed, for example 100m / minute or higher.
    Several modifications of the invention would be possible within the scope of the appended claims. For example, claim 1 describes a transport chain comprising a plurality of chain links, which are interconnected by means of a hinge segment between each chain link. Claim 1 is thus considered to refer to a transport chain in which all, most, some, or only two of its chain links are interconnected in the manner described in claim 1, i.e. certain chain links could be interconnected in another manner.
