[0001] Conveying apparatus and method for conveying a tire component
[0002] BACKGROUND
[0003] The invention relates to a conveying apparatus and a method for conveying a tire component, in particular a tire component comprising ferromagnetic material . More particularly, the invention relates to a conveying apparatus for trans ferring the tire component from a first conveyor below a conveyance plane to a second conveyor above said conveyance plane . The conveying apparatus may for example be a servicer for applying the tire component to the circumferential surface of a tire building drum . The invention further relates to a method for conveying a tire component .
[0004] JP S59 187836 A discloses a device and method in which the tip of a steel cord strip is placed on the rear end of the feeding face of a conveyor, a piston rod is advanced to move an overhead transfer conveyor forwards , and a friction roller is contacted with a friction roller . The transfer conveyor and a tire molding drum are driven, and the strip is attracted by a magnet and fed in a feeding direction towards the drum. The strip is put in the magnetic field of the magnet through a free roller, pulled to one side end of the feeding face of the conveyor, and then contacted with a guide roller . The strip is advanced on the free roller under guidance of the guide roller, during which period the strip is matched with a given sideward position while being supplied to the drum by the guide roller and floated in the magnetic field of the magnet of the conveyor .
[0005] SUMMARY OF THE INVENTION
[0006] A disadvantage of the device of JP S59 187836 A is that the overhead transfer conveyor and the feed conveyor obstruct access to the tire component at the transfer region in which the tire component is transferred from the feed conveyor to the trans fer conveyor . More particularly, the overhead conveyor prevents the inspection of the tire component at the trans fer region between the feed conveyor and the trans fer conveyor . Accordingly, a position of the tire component on either one of the conveyors cannot be accurately determined .
[0007] However, in the case that the feed conveyor and the transfer conveyor are spaced apart in the feeding direction to allow monitoring of the tire component during the trans fer from the feed conveyor to the trans fer conveyor, a leading end of the tire component that is being conveyed on the feed conveyor may curl up, i . e . the leading end may deflect upward with respect to the transport plane, prior to reaching the trans fer conveyor . Said curling up may cause the leading end to be folded over the remainder of the tire component . Moreover, the curling up and / or the folding over of the leading end may cause said leading end to be conveyed outside the reach of the retaining means of the transfer conveyor, causing the tire component to be dropped between the feed conveyor and the transfer conveyor .
[0008] It is an obj ect of the present invention to provide a conveying apparatus and a method for conveying a tire component, in which the tire component can be transferred from a first conveyor below the conveyance plane to a second conveyor above the conveyance plane more reliably .
[0009] According to a first aspect , the present invention relates to a conveying apparatus for conveying a tire component in a transport direction in a conveyance plane, in particular a tire component comprising ferromagnetic material , wherein the conveying apparatus comprises a first conveyor that is arranged below the conveyance plane for supporting the tire component in the conveyance plane from below and a second conveyor that is arranged above the conveyance plane for retaining the tire component in the conveyance plane from above, wherein the second conveyor is arranged downstream of the first conveyor in the transport direction and wherein the second conveyor is spaced apart with respect to the first conveyor in the transport direction, wherein the second conveyor comprises a retaining device for retaining the tire component to said second conveyor in the conveyance plane, wherein the conveying apparatus further comprises a correction member in a transition region in which the tire component is transferred from the first conveyor to the second conveyor, wherein the correction member is arranged below the conveyance plane and upstream of the second conveyor in the transport direction, wherein the correction member comprises a retaining element for retaining the tire component in the conveyance plane in a retaining direction when leaving the first conveyor, wherein the retaining direction has at least a vector component in a direction perpendicular to the conveyance plane .
[0010] The first conveyor and the second conveyor are spaced apart in the transport direction . Hence, the tire component can be accessed and / or inspected in the transition region between said first and second conveyors . The correction member can pull and / or retain the leading end of the tire component towards or at the conveyance plane . More particularly, the correction member can pull and / or retain the leading end of the tire component without obscuring and / or obstructing the transition region between the first and second conveyors . Accordingly, a curling up of said leading end can be prevented . Hence , the leading end of the tire component can be directed in the conveyance plane in the transition region from the first conveyor to the second conveyor . As a consequence , the leading end can be trans ferred from the first conveyor to the second conveyor more reliably .
[0011] Moreover, a region below the second conveyor can be more accessible . For example , said region below the second conveyor can be dedicated for transferring the tire component from the second conveyor to a tire building drum. In other words , by arranging the correction member upstream of the second conveyor, interference between the correction member and the tire building drum or a tire component supported on said tire building drum can be prevented .
[0012] In an embodiment thereof , the retaining direction extends perpendicular to the conveyance plane . Hence, the correction member can retain the tire component without or substantially without pulling the tire component in the transport direction . Hence, deformation of the tire component in the transport direction can be prevented .
[0013] In a further embodiment, the retaining element comprises one or more magnets . Alternatively, the retaining element may for example comprise a vacuum system for pulling the tire component towards the conveying plane using a suction force . The magnets can be suitable for pulling ferromagnetic elements , in particular steel cords , within the tire component towards the conveyance plane .
[0014] In a preferred embodiment thereof , a magnetic field of said magnets is directed in a direction perpendicular to the conveyance plane at the conveyance plane .
[0015] In a further embodiment , the conveying apparatus further comprises one or more sensors for detecting the tire component at a position between the first conveyor and the second conveyor in the transport direction . The sensor may for example be arranged for detecting a position of a leading end and / or a lateral position of the tire component .
[0016] In a further embodiment, the correction member is a correction roller, wherein the correction member comprises a rotation body that is rotatable with respect to said retaining element about a rotation axis that extends parallel to the conveyance plane and transverse or perpendicular to the transport direction . The correction roller, in particular the rotation body, can facilitate the conveying of the tire component in the transport direction . More particularly, the rotation body can reduce friction between the tire component and the correction member . The retaining element can retain the tire component in the retaining direction independent of the rotation of the retaining body relative to said retaining element . In other words , the correction roller can rotate without changing the retaining direction of the retaining element . Accordingly, the retaining element can pull the tire component in the retaining direction at a fixed circumferential position of the rotation body . Hence, the retaining element can pull the tire component in the retaining direction without or substantially without pulling the tire component in a circumferential direction of the rotation body . Accordingly, a downward deflection of the tire component , away from the conveyance plane , due to the pulling of the retaining element can be prevented . Thus , the tire component can be transferred to the second conveyor more reliably .
[0017] In a further embodiment, the correction member is located between the first conveyor and the second conveyor in the transport direction . In other words , the correction member is arranged downstream of the first conveyor and upstream of the second conveyor in the transport direction . Hence, the leading end of the tire component can first be transferred from the first conveyor to the correction member before transferring said leading end to the second conveyor . The correction member can be separate or distinct from the first conveyor . In a further embodiment , the first conveyor is movable relative to the second conveyor in a lateral direction parallel to the transport plane and transverse to the transport direction . Preferably, the correction member is movable in the lateral direction together with the first conveyor . An upstream portion of the tire component can be retained by the correction member and a downstream portion of the tire component can be retained by the retaining device of the second conveyor . Hence, while moving the first conveyor in the lateral direction relative to the second conveyor, a lateral position of a downstream portion of the tire component can be corrected relative to the upstream portion .
[0018] In an embodiment thereof , wherein the conveying apparatus further comprises a lateral detector for detecting a lateral position of the tire component between the correction member and the second conveyor, and a control unit that is functionally coupled to the lateral detector and the first conveyor, wherein the control unit is arranged to move the first conveyor in the lateral direction in response to the lateral detector detecting the lateral position of the tire component . Hence, the tire component can be corrected based on the lateral detector signals .
[0019] In an alternative embodiment thereof , the correction member is an end roll of the first conveyor . In other words , the correction member can be a part of the first conveyor .
[0020] In an embodiment thereof , the first conveyor is a belt conveyor, and wherein the correction member is head pulley or a tail pulley of the first conveyor . Alternatively, the conveyor may for example be a roller conveyor .
[0021] In a further embodiment , the conveying apparatus further comprises a catcher for urging at least a leading end of the tire component towards the conveyance plane at or near the location of the correction member . The catcher can urge and / or press the tire component towards or onto the correction member . In particular, the catcher can urge and / or press the leading end of the tire component towards or onto the correction member . Accordingly, the leading end of the tire component can be brought closer to the correction member . Hence , the retaining element can retain the tire component in the conveyance plane more reliable . The retaining element can retain the tire component to the correction member without the need of the correction member pushing the tire component onto the correction member . Hence, deformation of the tire component can be reduced .
[0022] In an embodiment thereof , the catcher comprises a belt conveyor with a conveyor belt, wherein the conveyor belt extends above the conveyance plane in a catching plane at an oblique catching angle with respect to the conveyance plane . Preferably, the conveyor belt of the conveyor is rotated or advanced along said catching plane towards the conveyance plane for urging the leading end of the tire component towards the conveyance plane . Thus , the leading end can be gradually urged towards the catching plane while the tire component is conveyed in the transport direction .
[0023] In an embodiment thereof , the catcher comprises a pulley at a downstream end of the catcher in the transport direction, wherein the pulley is movable towards and away from the conveyance plane . Hence , the leading end of the tire component can actively be pushed towards the conveyance plane by the pulley .
[0024] In an embodiment thereof , the conveying apparatus further comprises a leading end detector for detecting the leading end of the tire component between the correction member and the second conveyor, and a control unit that is functionally coupled to the leading end detector and the catcher, wherein the control unit is arranged to move at least the pulley of the catcher towards the conveyance plane in response to the leading end detector detecting the leading end of the tire component . In other words , the downstream pulley of the catcher can be moved in response to the leading end detector detecting the presence and / or passing of the leading end of the tire component past the correction member in the transport direction . Hence, the catcher can automatically urge said leading end in the retaining direction towards the conveyance plane upon detection of said leading end .
[0025] According to a second aspect, the present invention provides a method for conveying a tire component in a transport direction in a conveyance plane using the conveying apparatus according to the first aspect of the invention, wherein the method comprises the steps of : a) conveying the tire component on the first conveyor in the transport direction towards the second conveyor ; b) pulling a leading end of the tire component towards the correction member in the retaining direction; and c) transferring the leading end to the second conveyor .
[0026] The method comprises the use of the conveying apparatus of the first aspect of the invention and, hence, has the same advantages as mentioned above . Step b) may comprise pulling the leading end of the tire component closer to the correction member over a pulling distance . Additionally or alternatively, step b ) may comprise retaining the tire component to the correction member by a pulling force . Steps b) and c) may be performed subsequently or simultaneously .
[0027] In an embodiment thereof , the method further comprises , prior to step b ) or during step b) , the step of pushing the leading end towards the conveyance surface at or near the correction member . By pushing the leading end of the tire component towards the correction member, said correction member can more reliably retain said leading end .
[0028] In a further embodiment, the method further comprises , during step b) , moving the first conveyor and the correction member relative to the second conveyor in a lateral direction transverse or perpendicular to the transport direction . The tire component can be retained to the correction member in the retaining direction while retaining a downstream end of the tire component by the retaining device of the second conveyor . Hence, a movement of the tire component at the correction member in the lateral direction can be minimi zed . Accordingly, a lateral position of a section of the tire component upstream of the correction member in the transport direction can effectively be corrected by moving the first conveyor and the correction member relative to the second conveyor in the lateral direction . By retaining the tire component at the correction member, a shifting or deformation of the tire component at the second conveyor can be prevented .
[0029] The various aspects and features described and shown in the specification can be applied, individually, wherever possible . These individual aspects , in particular the aspects and features described in the attached dependent claims , can be made subj ect of divisional patent applications .

[0061] A method for conveying the tire component 9 using the conveying apparatus 1 according to the present invention will now be described using figures 1-3 and 5- 8 .
[0062] As is shown in figures 1 and 5, the tire component 9 has been provided on the first conveyor 2 in the conveyance plane P . The tire component 9 is supported on the support surface 20 of said first conveyor 20 . The tire component 9 has been conveyed in the transport direction T into a first position in which the leading end LE of the tire component 9 is located upstream of the correction member 5 in the transport direction T .

In said passive position a distance between the conveyance plane P and the fifth pulley 42 is larger than a distance between the conveyance plane P and the abutment surface 30 of the second conveyor 3 .
[0063] As is shown in figure 2 , the tire component 9 has been conveyed in the transport direction T by the first conveyor 2 into a second position . The leading end LE of the tire component 9 has been urged towards the conveyance plane P . Preferably, the leading end LE has been pulled towards the correction member 5 in the retaining direction Y .

[0064] As is best shown in figure 2 , the leading end LE of the tire component 9 has been conveyed in the transport direction T up to and / or past the leading end detector 61 . Accordingly, said leading end LE has been detected by the leading end detector 61 . In response, the control unit 7 has controlled the catcher 4 to move from the passive position towards the conveyance plane P into an active position . In particular, the catcher 4 has been moved towards the conveyance plane P into contact with an upper surface of the tire component 9.
[0065] In the embodiment as shown, the fifth pulley 42 of the catcher 4 has been moved from the passive position towards the conveyance plane P for urging the tire component 9 towards the correction member 5 . Preferably, the fifth pulley 42 has been moved towards the conveyance plane P for pressing the tire component 9, in particular the leading end LE of the tire component 9 , onto the correction member 5.

[0067] As is shown in figure 7 , the control unit 7 has controlled the first conveyor 2 and the correction member 5 to move in the lateral direction L relative to the second conveyor 3 in response to the detected lateral positions of the tire component 9.
[0068] While moving the first conveyor 2 and the correction member 5 in the lateral direction L, the tire component 9 is retained in the lateral direction L by the correction member 5. Preferably, the tire component 9 is further retained in the lateral direction L by clamping said leading end LE between the catcher 4 and the correction member 5 . Simultaneously, the leading end LE of the tire component 9 is retained in the lateral direction L by the retaining device 34 of the second conveyor 3 .
