DETAILED DESCRIPTION
(31) The apparatus 11 shown in
(32) The carriers 13 are placed on a holder 15 or fixed therein, wherein a holder 15 can receive two carriers 13 disposed next to one another transversely to the transport direction T. A respective holder 15 is carried by two transport movers 17 arranged behind one another along the transport direction T. Such an arrangement of two transport movers 17 behind one another which have a common holder 15 is also called a transport mover system 19 herein.
(33) Examples of such transport mover systems 19 are shown in
(34) The apparatus 11 of
(35) The movement of the transport movers 17 in the path system 21 takes place by means of a magnetic conveying technology and/or linear motor technology which is known per se. In the system shown, it takes place by substantially vertically acting magnetic forces between the linear motor of the path system 21 and the magnetic region 41 of a transport mover 17. In accordance with the invention, this also includes drives with a horizontal action of magnetic forces as a drive system. The apparatus 11 has a control device, not shown, for controlling the movements of the transport movers 17 in the path system 21. The control device and the process of controlling the transport movers 17 along the path are known per se.
(36) The path system 21 has a guide 23 for guiding the transport movers 17 along the path, said guide being formed by two parallel guide rails 25 in the variant shown in
(37) The respective rolling element or sliding element 27, 29 is disposed on the upper side 31 of one of the guide rails 25 and rolls or slides on this upper side 31 when the transport mover 17 moves along the transport direction T. The guide rails 25 therefore mainly take up vertical forces via the rolling elements or sliding elements 27, 29 arranged on them and provide a running surface (surfaces 31) for the rolling elements or sliding elements 27, 29.
(38) As
(39) The width of the gap 37measured from the lower side of the rolling elements or sliding elements 27, 29 up to the upper side of the projection 35is preferably selected such that it is slightly larger, for example a few millimeters, than the thickness of the protrusion 33 or of the free end of the metal angle sheet forming a guide rail 25.
(40) In addition to a so-called functional region 39, the transport mover 17 has a magnetic region 41 attached to the functional region 39. As
(41) The functional region 39 is preferably formed in one piece, for example from plastic, and has a flat lower side which is contacted by the likewise flat upper side of the magnetic region 41. A peripheral O-ring seal 43 which is preferably received in a peripheral groove formed at the upper side and/or at the lower side is provided in the marginal region between the upper side and the lower side of the two regions 39, 41. The seal 43 seals the gap of the interface between the functional region 39 and the magnetic region 41 at all sides. The seal 43 is preferably inwardly offset somewhat behind the outer side of the functional region 39 or of the magnetic region 41. The seal 43 can also serve as tolerance compensation between the functional region 39 and the magnetic region 41.
(42) As
(43) A fastening element 51 configured as a mushroom head screw is plugged into each first passage 45 and is fixed to the upper side of the magnetic region 41 in that it is screwed into a thread provided at the upper side of the magnetic region 41.
(44) The fastening element 51 has a recess complementary to the axle 49 at a spacing from the upper side of the magnetic region 41 which substantially corresponds to the spacing of the second passage 47 from the upper side of the magnetic region 41. If the axle 49 is plugged into the second passage 47, the upper, free end of the fastening element 51 engages behind the axle 49 above the region in which the two passages 45, 47 intersect. A fixing or a tensioning of the magnetic region 41 with respect to the functional region 39 thereby takes place. A secured connection between the functional region 39 and the magnetic region 41 is thus implemented.
(45) Each axle 49 is preferably formed from stainless steel. Each axle 49 is arranged in the respective second passage 47 in a manner secure against rotation.
(46) A central prolongation 53 which has an external thread can be provided at each rolling element 27 such that the prolongation 53 can be screwed into an internal thread at the axle 49 in order to fasten a respective rolling element 27 to the axle (cf.
(47) A sliding element 29 can be fixed to the functional region 39 by means of screws 59, whereincomparable with a rolling element 27a respective screw 59 can be screwed into an internal thread of an axle 49 (the screws 59 are shown in
(48) The holder 15 is rotatably connected to the functional region 39 by means of a rotary axle 61. The rotary axle 61 is in this respect rotatably arranged in a further passage 63 which extends in the vertical direction within the functional region 39 (cf.
(49) A plain bearing 65 can be provided at the upper end of the passage 63 for the rotatable support of the rotary axle 61 at the functional region 39. It can have a collar which is disposed on the upper side of the functional region 39, whereby the plain bearing 65 is fixed in its position in the passage 63. The plain bearing 65 can act horizontally and/or vertically.
(50) A further plain bearing 73 can also be provided in the lower region of the passage 63; it can likewise act horizontally and/or vertically and it ensures the rotational movability of the rotary axle 61 with respect to the functional region 39. A damping effect can furthermore be achieved by the plain bearing or plain bearings 65, 73.
(51) As
(52) A rotational movability of the holder 15 with respect to the transport mover 17 is ensured by the connection between the functional region 39 and the holder 15 implemented via the rotary axle 61, which is in particular advantageous if the transport moversas
(53) As
(54) Plain bearings without a collar can also be provided as an alternative to the upper plain bearing 65 having a collar and/or to the lower plain bearing 73 which can also comprise a collar.

(61) In a modified variant, the rolling elements 27 at both longitudinal sides of the transport mover 17 can be arranged at the same connection element 87 which then substantially forms the functional region of the transport mover 17 and at which the holder 15, as is schematically shown in
(62) In the transport system of
(63) The connection element 87 comprises a first section 87a whose one end is arranged at the pivot axis S and at whose other, free end 85 one of the rolling elements 27 is arranged. The connection element 87 furthermore comprises a second section 87b whose one end is arranged at the pivot axis S and at whose other, free end 85 the other one of the rolling elements 27 is arranged. In the variant represented in
(64) A central support of the rolling elements 27 (cf.

(71) As mentioned above, provision is made that two transport movers 17 are coupled to one another via the holder 15 in a transport mover system 19. As
(72) An elastic and/or a rotationally movable coupling of the two transport movers 17 can alternatively be achieved via a hinge 99 (

(75) The openings 93 can be provided at elastic arms 107 in the sliding element 29 of
(76)
(77) The adjustability of the spacing of the two transport movers 17 is in particular of advantage during a cornering. If the transport movers 17 have a larger spacing, a carrier disposed at the holder 15 moves on a smaller, inner radius which is smaller than the path route radius. Centrifugal force influences are thereby reduced. The cornering speed can additionally be reduced. The spacing between the transport movers 17 can be reduced again or set to a normal value after travelling through a corner.
