Abstract
The invention relates to a device for transferring a transport car which can be displaced on a track system from a first track section of the track system that is arranged on a first level, to a second track section of the track system that is arranged on a second level different from the first level. The device comprises at least one first and one second transfer carriage which can carry at least one respective transport car to be transferred and which can be displaced in opposite directions on two different levels. The invention further relates to a conveyor system for transporting articles.
Description
- The invention relates to a device for transferring a transport car which can be moved on a track system from a first track section of the track system, which is arranged on a first level, to a second track section of the track system which is arranged on a second level different from the first level. Devices of this type are necessary for example in electric overhead conveyors, in which there are different sections of the track system which are arranged on different levels.
- The invention moreover relates to a conveyor system for transporting articles having
-
- a) a track system comprising a first track section, which is arranged on a first level, and a second track section, which is arranged on a second level different from the first level;
- b) a plurality of driveable transport cars, by means of which at least one article can be moved on the track system in each case;
- c) a transfer device by means of which the transport cars can be transferred from the first track section to the second track section.
- The height difference between track sections of a conveyor system of this type can be bridged for example by way of inclined track sections. However, the inclination of said inclined track sections with respect to a horizontal plane must not be too great so that a transport car can negotiate an ascending or descending section without difficulty. Accordingly, the length of this type of inclined track section in the transport direction is always dependent on the height difference to be negotiated between the two track sections of the track system which are arranged on different levels and the maximum possible inclination of an inclined section arranged between them
- To save on this necessary installation space in the transport direction, devices of the type mentioned at the outset are sometimes used. Devices of this type which are known from the market comprise a transfer carriage which can be moved between a level associated with the lower track section and a level associated with the upper track section of the track system. The installation space required here in the transport direction is smallest when the transfer carriage is moved vertically.
- If a transfer procedure is to take place for example from a lower track section to an upper track section of the track system, the transfer carriage receives a transport car from the lower track section, is moved to the upper track section and releases the transport car again there.
- The now empty transfer carriage is then moved to the lower track section again where it receives a further transport car, and so on.
- The throughput of a transfer device of this type is, however, limited. Particularly in electric overhead conveyors with a plurality of transport cars, situations can arise in which very many transport cars have to be transferred in as short a time as possible from a lower track section to an upper track section, or vice versa.
- To increase the maximum throughput when transferring the transport cars, two parallel connected transfer devices of the type mentioned at the outset are normally used, with the track sections connected to the now two transfer devices by way of respective points. However, this solution is relatively expensive since two transfer devices and two points arrangements are required, with the latter additionally requiring corresponding control components.
- Therefore, the object of the invention is to improve a device of the type mentioned at the outset to the effect that its throughput is increased in more economical manner.
- In a device of the type mentioned at the outset, this object is achieved in that it comprises at least one first and one second transfer carriage which can each carry at least one transport car to be transferred and which can be moved in opposite directions between two levels.
- The throughput of the device can be doubled as a result of the fact that the transfer device now comprises two transfer carriages which can be moved in opposite directions between two levels. To this end, the transfer carriages are arranged for example so that the one transfer carriage is located on a level associated with the upper track section of the track system when the second transfer carriage is located on a level associated with the lower track section of the track system. It is thus possible, for example, for a transport car to move onto the second transfer carriage at the bottom whilst a transport car which has already been transferred with the first transfer carriage can move onto the upper track section at the top. Whilst the second transfer carriage is then moved upwards, the first transfer carriage, in the meantime, can move downwards to the lower track section of the track system so that the positions of the two transfer carriages are switched. Then a transport car can move out of the transfer device again at the top, whilst a transport car moves into the transfer device at the bottom and the transfer procedure can be carried out again without the transfer carriage located at the top having to first of all move downwards for this, as is the case in known transfer devices.
- Advantageous further developments of the invention are described in dependent claims.
- It is particularly advantageous if the transfer carriages can be moved in each case along a vertical guide track. This minimises the installation space required for the transfer device in the transport direction.
- In view of its counter-directional movement between the two levels, care must be taken to ensure that the two transfer carriages do not impede one another on their movement path, in particular that one of the transfer carriages does not collide with a transport car carried by the other transfer carriage. This is achieved in that at least one of the two transfer carriages has a carrying device for the transport car, which is mounted such it can pivot about a pivot axis. This measure enables obstructing components of the one transfer carriage to be pivoted out of the sphere of influence of the other, oncoming transfer carriage, or the transport car which is possibly carried by this, when the two transfer carriages move past one another in opposite directions.
- It is particularly favourable here if the pivot axis extends horizontally.
- In this connection, it can moreover be helpful if at least one of the two transfer carriages can be moved horizontally. This can also prevent a collision between the mutually approaching transfer carriages.
- This can be effected, for example, in that the transfer carriages are guided by a carrying structure which can be moved horizontally. In this case, for example, the two transfer carriages are not moved relative to one another but are moved horizontally together with the carrying structure guiding them.
- To this end, it is advantageous if the carrying structure runs in a horizontal guide track by means of rollers. It is thus possible to achieve a positively driven and precise movement.
- In a modification, it is favourable if the vertical guide tracks for the transfer carriages comprise an upper section, a central section and a lower section and drive means are present by means of which the upper section and the lower section can be moved horizontally. In this case, the transfer carriages can be moved horizontally with the movable upper or lower section, thus enabling a relative movement of the two transfer carriages in the horizontal direction.
- It is advantageous here if the drive means are arranged so that the transfer carriages can be moved horizontally independently of one another. It is thus possible to respond to particular situations when transferring the transport cars. It also enables easier maintenance.
- It is particularly advantageous if the guide tracks comprise a first central section and a second central section which are arranged at a mutual spacing in the horizontal direction, wherein the upper section and the lower section of the vertical guide tracks can be moved in each case between a respective first position, in which these are aligned with the first central section, and a respectine second position in which these are aligned with the second central section. This means that a lower, a central and an upper track section is not associated with each of the two transfer carriages. Instead, the transfer carriages share a single lower section and a single upper section.
- The object of the invention is moreover to provide a conveyor system of the type mentioned at the outset, which takes the above ideas into account.
- This object is achieved by a conveyor system of the type mentioned at the outset in that
-
- d) a transfer device according to one of claims 1 to 10 is provided as the transfer device.
- A transfer device according to the invention can be used particularly well and efficiently if the conveyor system is constructed in the manner of an electric overhead conveyor.
- Exemplary embodiments of the invention are explained in more detail below with reference to the drawings, which show:
-
FIG. 1 a side view of a partial section of a conveyor system for transporting articles, wherein a device for transferring a transport car between two track sections arranged on different levels is shown schematically; -
FIGS. 2 to 5 a view in each case in the transport direction of a first exemplary embodiment of the transfer device, wherein different phases of the transfer of transport cars from the lower track section to the upper track section of the track system are shown; -
FIG. 6 a view corresponding toFIGS. 2 to 5 of a second exemplary embodiment of the transfer device; -
FIG. 7 a view corresponding toFIG. 6 of a third exemplary embodiment of the transfer device; -
FIG. 8 a view in the transport direction of a fourth exemplary embodiment of the transfer device; -
FIG. 9 a side view of the transfer device ofFIG. 8 . - In Figure one, a conveyor system (of which a detail is shown) constructed in the manner of an electric overhead conveyor for transporting articles is denoted as a whole by 10. The
conveyor system 10 comprises atrack system 12 with afirst carrying track 14 and asecond carrying track 16 which extend at different heights over the level of abase 18. The first carryingtrack 14 is arranged on a first level which is located underneath a second level on which the second carryingtrack 16 is arranged. - The
carrying tracks - The
conveyor system 10 moreover comprises a plurality oftransport cars 20 of which three transport cars (20 a, 20 b, 20 c) are illustrated inFIG. 1 and which can be moved on thecarrying tracks carrying tracks arrows 22. - Contact lines (not shown specifically), which serve to supply power to the
transport cars 20 and to transmit signals to these, extend along thecarrying tracks - Each
transport car 20 comprises atravel mechanism 24 which reaches around the carryingtrack FIGS. 2 to 7 and 9) which rolls along the top of the carrying tracks 14 or 16 and receives the load transported by thetransport car 20. Eachtransport car 20 is driven by means of an electric motor (not shown specifically here) which is powered and controlled in conventional manner by way of the said contact lines. Thetravel mechanism 24 is prevented from tipping and tilting relative to a vertical and a horizontal plane by measures which are known per se. - To enable the transportation of articles by means of the
transport car 20, this latter has a suspended transport means 28 which is connected to thetravel mechanism 24 of thetransport car 20 by way of acoupling element 30. - Located between the on the
lower carrying track 14 and the upper carryingtrack 16, there is a transfer device (merely indicated schematically inFIG. 1 ) by means of which atransport car 20 arriving from thelower carrying track 14 can be lifted and transferred to the upper carryingtrack 16. By means of thetransfer device 32, thetransport car 20 can overcome the height difference between thelower carrying track 14 and the upper carryingtrack 16 without necessitating an ascending section of thetrack system 12 for this, which would need to have a larger extent in thetransport direction 22 than thetransfer device 32. -
FIG. 2 shows atransfer station 34 as a first exemplary embodiment of thetransfer device 32. This transfer station is constructed in the manner of a gantry and comprises a carryingframe 36 with a firstvertical guide track 38 and a secondvertical guide track 40. The vertical guide tracks 38 and 40 extend to the left and right (as seen in the transport direction) next to the vertical plane specified by the carryingtracks - A
first transfer carriage 42 is guided by means of the firstvertical guide track 38 in such a way that it can only be moved in the vertical directions indicated inFIG. 2 by a double-headedarrow 44. To this end, thefirst transfer carriage 42 comprises a carriage travel-mechanism 46 which supports guiderollers 48 which cooperate with the firstvertical guide track 38 and can each be rotated about a horizontal axis of rotation extending parallel to thetransport direction 22. - An
extension arm 50 is connected in articulated manner to the carriage travel-mechanism 46 and can be pivoted about ahorizontal pivot axis 54, which extends parallel to thetransport direction 22, between a carrying position and a no-load position (shown inFIG. 5 ) by way of a joint 52. Thatfree end 56 of theextension arm 50 which is opposite the joint 52 carries atrack piece 58 which has the same I-shaped profile as the carrying tracks 14 and 16. The dimensions of theextension arm 50 and the arrangement of thetrack piece 58 on this are determined such that thetrack piece 58 is arranged in the vertical plane specified by the carryingtracks extension arm 50 of thefirst transfer carriage 42 assumes its carrying position. In the no-load position of theextension arm 50, this is pivoted upwards about thepivot axis 54 so that thetrack piece 58 finds itself at a spacing from the vertical plane specified by the carryingtracks - The
transfer station 34 moreover comprises asecond transfer carriage 60 which, in terms of its construction, corresponds substantially to thefirst transfer carriage 42, so components corresponding to those of thefirst transfer carriage 42 are denoted by the same reference numerals in the second transfer carriage. - The
second transfer carriage 60 is also guided by itsguide rollers 48 over the secondvertical guide track 40 in such a way that it can only be moved in the vertical directions (cf. double-headed arrow 44). - Deviating from the
first transfer carriage 42, thetrack piece 58 is not mounted directly on thefree end 56 of theextension arm 50. Instead, thefree end 56 of theextension arm 50 of thesecond transfer carriage 60 carries a holdingstructure 62 reaching around itstrack piece 58 so that thetrack piece 58 of thesecond transfer carriage 60 is carried from the same side as thetrack piece 58 is carried by theextension arm 50 of thefirst transfer carriage 42. A spacing therefore remains between thetrack piece 58 of thesecond transfer carriage 60 and thefree end 56 of itsextension arm 50 so that thetravel mechanism 24 of atransport car 20 can move onto thetrack piece 58 of thesecond transfer carriage 60 and is thereby likewise surrounded by the holding structure 62 (cf.FIG. 5 ). - The
extension arms 50 of the first and thesecond transfer carriage strut 64 which abuts against the respective carriage travel-mechanism 46 when thecorresponding extension arm 50 assumes its carrying position. Thus, for thetransfer carriages extension arm 50 is prevented when this occupies its carrying position. - The carrying
frame 36 of thetransfer station 34 comprises anoverhead crossbeam 66 which supports twodeflection rollers transport direction 22. Adrive pinion 74, which can be driven by means of anelectric motor 72, is arranged between thedeflection rollers transfer carriages chain 78 which runs on thedeflection roller 68, thedrive pinion 74 and thedeflection roller 70. Thedeflection rollers chain 78 extends substantially vertically downwards from thedeflection roller 68 to thefirst transfer carriage 42 and substantially vertically downwards from thedeflection roller 70 to thesecond transfer carriage 60. - In a modification, instead of the
chain 78, it is also possible to use a cable, a belt or the like in conjunction with drive means which are adapted thereto and known per se. - The
drive pinion 74 can be rotated optionally in a first direction indicated by thearrow 80 or in the opposing direction indicated by anarrow 82 by means of theelectric motor 72. If thedrive pinion 74 is rotated in the direction of thearrow 80, thefirst transfer carriage 42 moves upwards whilst thesecond transfer carriage 60 is moved downwards. If, on the other hand, thedrive pinion 74 is rotated in the direction of thearrow 82, then thefirst transfer carriage 42 moves downwards and thesecond transfer carriage 60 moves upwards. The first and thesecond transfer carriages second transfer carriages chain 78. - The
transfer station 34 described above now functions as follows: - In
FIG. 2 , thefirst transfer carriage 42 is shown in its bottommost position in which it is located on a first level. In this bottommost position of thefirst transfer carriage 42, itstrack piece 58 is in alignment with thelower carrying track 14 of thetrack system 12. - The
second transfer carriage 60, on the other hand, assumes its topmost position in which it is located on a second level. In this topmost position thetrack piece 58 of thesecond transfer carriage 60 is in alignment with the upper carryingtrack 16 of thetrack system 12. - The
transport car 20 a (cf. alsoFIG. 1 ) rolling on thelower carrying track 14 now arrives in thetransfer station 34, whereupon it moves onto thetrack piece 58 of thefirst transfer carriage 42. In this position, thetransport car 20 a is fixed on thetrack piece 58 of thefirst transfer carriage 42 by means of a braking device (not shown specifically here). - The
drive pinion 74 is now moved in the direction of thearrow 80 by means of theelectric motor 72 so that thefirst transfer carriage 42 with thetransport car 20 a travels upwards and the emptysecond transfer carriage 60 travels downwards. This is shown inFIG. 3 . If thesecond transfer carriage 60 moves downwards, itsextension arm 50 is pivoted upwards by way of the joint 32, as shown inFIG. 3 , so that theextension arm 50 with the holdingstructure 62 and thetrack piece 58 of thesecond transfer carriage 60 does not collide with thetransport car 20 a held by thefirst transfer carriage 42. This pivotal movement of theextension arm 50 of thesecond transfer carriage 60 can be effected for example by means of an electric motor (not shown specifically here) or by means of a sliding guide which is known per se. - The
first transfer carriage 42 is moved upwards with thetransport car 20 a until it assumes its topmost position within thetransfer station 34 in which it is located on the same level as thefirst transfer carriage 42 before in its topmost position (cf.FIG. 4 ). - The
track piece 58 of thefirst transfer carriage 42 is now in alignment with the upper carryingtrack 16 of thetrack system 12. Thetransport car 20 a is now moved from thetrack piece 58 of thefirst transfer carriage 42 onto the upper carryingtrack 16 of thetrack system 12 and from there further to its destination. - At this point in time, the
second transfer carriage 60 assumes its bottommost position in thetransfer station 34, in which it is located on the same level as thefirst transfer carriage 42 in its bottommost position. With this, theextension arm 50 of thesecond transfer carriage 60 now assumes its carrying position again so that thetrack piece 58 is in alignment with thelower carrying track 14 of thetrack system 12 in thetransport direction 22. - Whilst, at the top, the
transport car 20 a descends from thefirst transfer carriage 42, afurther transport car 20 d, at the bottom in the transfer station, moves onto thetrack piece 58 of thesecond transfer carriage 60. Thedrive pinion 74 is then moved in the direction of thearrow 82 by means of theelectric motor 72, as a result of which thefirst transfer carriage 42 is moved in its empty state downwards and thesecond transfer carriage 60 is moved upwards with thetransport car 20 d. Theextension arm 50 of thefirst transfer carriage 42 also assumes its no-load position in which it is pivoted upwards about thepivot axis 54 when it is moved downwards. - The
drive pinion 74 is moved in the direction of thearrow 82 until thefirst carriage 42 assumes its bottommost position (shown inFIG. 2 ) and thesecond transfer carriage 60 assumes its topmost position (likewise shown inFIG. 2 ) in thetransfer station 34. Theextension arm 50 of thefirst transfer carriage 42 is brought back into its carrying position. Whilst, at the top, thetransport car 20 d now moves from thesecond transfer carriage 60 onto the upper carryingtrack 16 of thetrack system 12, at the bottom afurther transport car 20 can move onto thefirst transfer carriage 42 and the procedure explained above can be repeated. - The
transfer station 34 can also be used to transfertransport cars 20 from the upper carryingtrack 16 to thelower carrying track 14 of thetrack system 12. In this case, theextension arms 50 of thetransfer carriages extension arms 50 of thetransfer carriages transfer carriages -
FIG. 6 shows atransfer station 1034 as a second exemplary embodiment of thetransfer device 32. In this, components which correspond to those of thetransfer station 34 according toFIGS. 2 to 5 are denoted by the same reference numerals plus 1000. - The
transfer carriages transfer station 1034 differ from thetransfer carriages respective extension arm 1050 is rigidly connected to the respective carriage travel-mechanism 1046. - The
extension arms 1050 of thetransfer carriages track pieces 1058 do not extend in a common vertical plane but, as seen in thetransport direction 22, are arranged laterally offset from one another so that thetransfer carriages respective extension arms 1050 colliding with one another. - So that a
transport car 20 arriving from thelower carrying track 14 of thetrack system 12 can now be transferred to the upper carryingtrack 16, the carryingframe 1036 of thetransfer station 1034 can be moved back and forth in a horizontal direction extending perpendicularly to thetransport direction 22. - To this end, the carrying
frame 1036 of thetransfer station 1034 is mounted onrollers 1084 which roll in aguide track 1086 anchored to thebase 18 of theconveyor system 10. The carryingframe 1036 of thetransfer station 1034 is connected to thepiston rod 1088 of ahydraulic cylinder 1090, as a result of which thecarrying frame 1036 can be moved back and forth between two positions whereby, in one position, thetrack piece 1058 of thefirst transfer carriage 1042 and, in the other position, thetrack piece 1058 of thesecond transfer carriage 1060 can be in alignment with thelower carrying track 14 or the upper carryingtrack 16 of the track system 112. - During the transfer procedure, the carrying
frame 1036 of thetransfer station 1034 is, for example, firstly brought into a position in which thetrack piece 1058 of thefirst transfer carriage 1042, in its bottommost position, is in alignment with thelower carrying track 14 of thetrack system 12. Then atransport car 20 moves onto thefirst transfer carriage 1042 and, as explained above, is conveyed upwards until thetrack piece 1058 of thefirst transfer carriage 1042 is in alignment with the upper carryingtrack 16 of thetrack system 12. - The
second transfer carriage 1060, which is located at this moment in its bottommost position in thetransfer station 1034, is at this point in time laterally offset from thelower carrying track 14 of thetrack system 12. - After the
transport car 20 has been moved from thefirst transfer carriage 1042 onto the upper carryingtrack 16 of thetrack system 12, a corresponding activation of thehydraulic cylinder 1090 causes the carryingframe 1036 of thetransfer station 1034 to be moved into a position in which thetrack piece 1058 of thesecond transfer carriage 1060 located in its bottommost position is now in alignment with thelower carrying track 14 of thetrack system 12. Afurther transport car 20 can now move from thelower carrying tack 14 onto thesecond transfer carriage 1060 and be transferred accordingly to the upper carryingtrack 16 of thetrack system 12. - Then a corresponding activation of the
hydraulic cylinder 1090 causes the carryingframe 1036 to be moved back into a position in which thefirst transfer carriage 1042, which now assumes its bottommost position in thetransfer station 1034, is arranged such that itstrack piece 1058 is in alignment with thelower carrying track 14 of thetrack system 12. -
FIG. 7 shows, as a further exemplary embodiment of thetransfer device 32, atransfer station 2034 in which components which correspond to those of thetransfer station 1034 ofFIG. 6 have the same reference numerals plus 1000. - Instead of the carrying frame 1046, the
transfer station 2034 has acarrying column 2092 which, on opposite sides, is constructed in each case as avertical guide track first transfer carriage 2042 or thesecond transfer carriage 2060. - The chain 2078 is merely guided by way of the
drive pinion 2074 here, which is dimensioned such that the chain 2078 extends in each case substantially vertically downwards to therespective transfer carriage - Whilst, in the
transfer stations extension arms transfer carriages extension arms 2050 of thetransfer carriages transfer station 2034 face away from one another. - Otherwise, the
transfer station 2034 functions in the manner explained above with regard to thetransfer station 1034 according toFIG. 6 . -
FIGS. 8 and 9 show, as a further exemplary embodiment of thetransfer device 32, atransfer station 3034 in which those components which correspond to the those of thetransfer station 2034 according toFIG. 7 are denoted by the same reference numerals plus 1000. - The
transfer station 3034 comprises a carryingstructure 3094 which is anchored laterally next to the carrying tracks 14, 16 of thetrack system 12 at thebase 18 of theconveyor system 10. - A front
vertical guide track 3096, which is constructed as an I-shaped profile, is mounted on the front side of the carryingstructure 3094, which faces the carrying tracks 14, 16, and a constructionally identical rearvertical guide track 3098 is mounted on the rear side of the carryingstructure 3094, which is remote from the carrying tracks 14, 16. Theses guidetracks region 3100 above thelower carrying track 14 of thetrack system 12 and below the upper carryingtrack 16 of thetrack system 12, are the same length and are aligned flush with one another in each case at the top and bottom. - Arranged above the guide tracks 3096, 3098, there is an upper
vertical guiding track 3102, whereof the cross-section corresponds to those of the guide tracks 3096 and 3098. Theupper guiding track 3102 can be moved horizontally between a rearmost position, in which it is in alignment with therear guide track 3098, and a frontmost position, in which it is in alignment with thefront guide track 3096. To this end, the upper guiding track 3012 is rigidly coupled to apiston rod 3108 of a correspondingly alignedhydraulic cylinder 3110 which acts as a displacing device. Theupper guiding track 3102 thus follows the translatory movement of thepiston rod 3108. Moreover, the rigid coupling between theupper guiding track 3102 and thepiston rod 3108 prevents theupper guiding track 3102 from tilting with respect to a vertical plane. - Analogously, a lower
vertical guiding track 3112, whereof the cross-section corresponds to that of the guide tracks 3096, 3098 and the upper guiding track 3012, is arranged below the guide tracks 3096. Thelower guiding track 3112 can also be moved horizontally between a rearmost position, in which it is in alignment with therear guide track 3098, and a frontmost position, in which it is in alignment with thefront guide track 3096. To this end, thelower guiding track 3112 is rigidly coupled to apiston rod 3118 of a correspondingly alignedhydraulic cylinder 3120 which acts as a displacing device for thelower guiding track 3112. - The two
transfer carriages transfer carriages extension arm 3050 caries thetrack piece 3058. Thetransfer carriages tracks mechanisms 3046 are constructed such that these reach around the guide tracks 3096, 3098 or the guidingtracks extension arms 3050 each project in the direction of the carrying tracks 14, 16 of thetrack system 12. - The first and the second transfer carriages additionally support
lateral guide rollers 3104 and 3114 (cf.FIG. 8 ) which can roll in upperhorizontal tracks 3106, which are arranged on the level of theupper guiding track 3102, and lowerhorizontal tracks 3116, which are arranged on the level of thelower guiding track 3112. - The
transfer station 3034 comprises twodeflection rollers structure 3094 and are fixed to acommon drive shaft 3126 which can be driven by means of anelectric motor 3128. The axis of thedrive shaft 3126 extends parallel to thetransport direction 22 of theconveyor system 10. - Moreover, the
transfer station 3034 comprises anupper deflection roller 3130, which is mounted at the top of the carrying structure and is arranged in vertical alignment with thelower deflection roller 3122, and a furtherupper deflection roller 3132, which is mounted at the top of the carrying structure and is arranged in vertical alignment with thelower deflection roller 3124. Theupper deflection rollers - A
continuous chain 3134 runs over thedeflection roller pair continuous chain 3136 runs over thedeflection roller pair continuous chains transfer carriages - Provided adjacent to the ends of the upper
horizontal tracks 3106 and the lowerhorizontal tracks 3116, there areupper stops 3138 andlower stops 3140 which cooperate with thelateral guide rollers transfer carriages - The
transfer station 3034 functions as follows: - In the phase of the transfer procedure shown in
FIGS. 8 and 9 , theupper guiding track 3102 has been displaced into its rearmost position by way of a corresponding activation of thehydraulic cylinder 3110. Thefirst transfer carriage 3042 is located with its guide rollers 3048 in theupper guiding track 3108 and lies with itslateral guide rollers upper stops 3138, thus preventing a further upward movement of thefirst transfer carriage 3042. - The
lower guiding track 3112 has been displaced into its frontmost position by way of a corresponding activation of thehydraulic cylinder 3120 associated with it. Thesecond transfer carriage 3060 is located with its guide rollers 3048 in thelower guiding track 3108 and assumes a vertical position in which itstrack piece 3058 is in alignment with thelower carrying track 14 of thetrack system 12 of theconveyor system 10. With this, it lies with itslateral guide rollers lower stops 3140, thus preventing a downward movement of thesecond transfer carriage 3060. - A
transport car 20 of theconveyor system 10 has already moved from thelower carrying track 14 of thetrack system 12 onto thesecond transfer carriage 3060 or onto itstrack piece 3058. - The
lower deflection rollers electric motor 3128 in such a way that thefirst transfer carriage 3042 travels downwards and thesecond transfer carriage 3060 with thetransport car 20 travels upwards. To this end, the above-mentioned carriers (not shown specifically) of thecontinuous chains transfer carriages continuous chains - With this, the
first transfer carriage 3042 travels out of theupper guiding track 3102 into therear guide track 3098 and thesecond transfer carriage 3060 travels out of thelower guiding track 3112 into thefront guide track 3096. - Whilst the
transfer carriages front guide tracks upper guiding track 3102 is pushed by means of thehydraulic cylinder 3110 associated therewith into its frontmost position and thelower guiding track 3112 is pushed by means of thehydraulic cylinder 3120 associated therewith into its rearmost position. - Then, the
second transfer carriage 3060 with thetransport car 20 travels out of thefront guide track 3096 into theupper guiding track 3102 and the unladenfirst transfer carriage 3042 travels out of therear guide track 3098 into thelower guiding track 3112. Thelower deflection rollers second transfer carriage 3060 lies with itslateral guide rollers upper stops 3138 on the front side of the carryingstructure 3094. In this position, thetrack piece 3058 of thesecond transfer carriage 3060 is in alignment with the upper carryingtrack 16 of thetrack system 12 of theconveyor system 10. - After this, the
transport car 20 travels from thesecond transfer carriage 3060 onto the upper carryingtrack 16 of thetrack system 12 and from there to its destination. - Meanwhile, the
lower guiding track 3112, together with thefirst transfer carriage 3042 guided therein, is pushed by means of thehydraulic cylinder 3120 associated therewith into its frontmost position. Here, thefirst transfer carriage 3042 lies firstly with itslateral guide rollers lower stops 3140 on the rear side of the carryingstructure 3094. Then it travels with itslateral guide rollers horizontal tracks 3116. This prevents a downward movement of thetransfer carriage 3042 in thelower guiding track 3112. Finally, thefirst transfer carriage 3042 comes to lie with alateral guide rollers lower stops 3140 on the front side of the carryingstructure 3094. Here, thefirst transfer carriage 3042 is aligned vertically so that itstrack piece 3058 is in alignment with thelower carrying track 14 of thetrack system 12, towards which afurther transport car 20 is already moving. - This
further transport car 20 now moves onto thefirst transfer carriage 3042. At the same time, theupper guiding track 3102, together with thesecond transfer carriage 3060, is pushed into its rearmost position which takes place in the manner explained above with regard to the horizontal movement of thefirst transfer carriage 3042. The situation now corresponds to that shown inFIGS. 8 and 9 , save that the positions of the first and thesecond transfer carriage - The transfer procedure explained above is now repeated accordingly.
