Technical Field
The invention relates to a drum set for manufacturing a bead apex for a tire and a device having said tool.
Background
WO2013/095106a1 discloses a tool for removing or installing drum segments of a manufacturing apparatus. The tool is provided with a support body and a plurality of connecting portions which interact with the connecting members on the drum segments to connect the drum segments to the support body. When attached, the drum segments can be removed from the manufacturing equipment with the tool. Known tools, when connected, hold the drum segments in place, thereby maintaining them in their respective positions. The tool, and the drum segments connected thereto, thereby enabling easy return to the manufacturing facility.
A disadvantage of the known tool is that each drum segment must be in the correct position to allow the connecting member to be connected to the tool. The drum segments must be carefully and accurately transferred from the manufacturing facility to the tool and vice versa to prevent misplacement or malfunction of the drum segments during operation of the manufacturing facility. Finally, the tool must be disconnected from the drum segments before the manufacturing equipment can be operated. During this time, the tool may be misplaced or used in a different set of drum segments so that, upon removal, there is no longer enough tool to remove the previously installed drum segment.
Disclosure of Invention
It is an object of the present invention to provide a drum set for manufacturing a bead apex for a tire and a device having said tools, wherein the handling of the drum set during mounting and/or removal can be improved.
According to a first aspect, the invention provides a device for manufacturing bead apexes for tyres, comprising a plurality of drum sets and a plurality of seats for simultaneously supporting the same number of said sets, wherein each drum set comprises a plurality of drum segments distributed around a central axis of the drum set to form a drum, wherein the drum defines a peripheral edge for receiving a bead, wherein the drum segments of the drum set are radially movable with respect to the central axis to expand and contract the peripheral edge, wherein the drum set is arranged to be movable between an operating position in which the drum set is supported on a seat for receiving a bead and a storage position in which the drum set is not supported by the seat, wherein the drum set further comprises support members for supporting the drum segments of the drum set with respect to each other, wherein the support members are provided with guides, for guiding the radial movement of the drum segments when the drum sets are in the operative position, and a guide is provided for holding the drum segments of the drum sets to the support members when the drum sets are in the storage position, wherein each base is provided with one or more mounting members for mounting a respective one of the plurality of drum sets in the operative position of the base, wherein the device further comprises a storage member for receiving the plurality of drum sets and a manipulator for mounting and removing one drum set relative to its base, wherein the manipulator comprises a robot arm having a degree of freedom enabling it to handle the drum sets at both the base and the storage member.
Thus, a selected drum set or set of drum sets from a plurality of drum sets may be used simultaneously on the same number of bases, for example, in the same number of device production stations. The drum segments of the drum set are removable from the base while being held in a set by the support member. This prevents mixing of the drum segments of different drum sets. Moreover, the tolerances and accuracy of the drum set during installation and operation can be significantly improved. Since the support member forms part of the drum set in the storage position and the operating position, the support member does not have to be removed during operation of the drum set. The storage means may be for storing a plurality of drum sets for later use. A robotic arm may be used to handle the drum sets at the base and storage members. In particular, the robot arm is arranged for transferring the drum set between an operating position on the base and a storage position on the storage member. Robotic arms may be used to assist or take over the manual placement and removal of the drum sets.
In one embodiment, the apparatus comprises a turntable rotatable about a turntable axis, wherein a plurality of bases are mounted to the turntable and distributed about the turntable axis for rotation by the turntable through different production stations. The drum sets are continuously movable through different production stations while various production operations are performed at each production station.
In one embodiment, the plurality of drum sets includes a number of identical drum sets equal to the number of pedestals. Thus, a set of identical drum sets may be selected for mounting on the same number of bases.
In one embodiment, the same set of drums forms a set of drums arranged to be used during production of a batch of the same bead apex. The groups may be used continuously as long as the batch properties remain unchanged. If a change in batch properties occurs, another group must be swapped between batches.
In one embodiment, the storage member is arranged to receive all drum sets of the same set. Thus, all drum sets of the same set may be held together to prevent mixing of drum sets of different sets.
In one embodiment, all drum sets of the same set are arranged to be stacked on the storage member. Stacking may reduce the space consumed by drum set storage.
In one embodiment, wherein each drum set in the set comprises indexing means for indexing the position of said drum set relative to the other drum sets within the set. This may improve the positioning of the drum sets during storage, for example, when the same drum set is to be mounted as a set to a plurality of pedestals.
In one embodiment, the storage member is movable and arranged to autonomously travel a path between a production position near the base and a more remote storage position. This may automate the storage process and prevent human error.
In one embodiment each drum segment is provided with a handling member, wherein the manipulator is provided with the same number of gripping members for gripping said handling members. The handling member allows for a firm clamping of the drum set at the drum segments by the manipulator.
In one embodiment, the handling member and the gripping member are formed as hooks that mate, engage and/or snap into each other. The hooks can be engaged in a relatively simple manner without the need for further fixing means by radially moving the gripping members into engagement with the processing members at the drum segments.
In one embodiment, a clamping member is additionally provided for placing and/or removing the bead or bead apex relative to the drum set. Thus, the same manipulator may be used for mounting and removal of the drum set and for placement and removal of the beads and/or bead apexes.
In one embodiment, the drum segments are circumferentially spaced apart from each other to form a radially extending access channel between the drum segments, wherein the clamping members are arranged to be inserted into the access channel and to be moved radially outwardly into engagement with the beads or bead apexes at the peripheral edge of the drum. The access passage allows the clamping member to be moved into the drum disposed to the bead or bead apex position.
In one embodiment, the treatment member is offset in circumferential direction with respect to the access passage, wherein the manipulator comprises a gripping head rotatable around a central axis of the drum, wherein the gripping member is arranged on the gripping head, the gripping head radially aligning the gripping member with the access passage or the treatment member around the central axis of the drum. Thus, it is possible to switch between the clamping drum set and the clamping bead or bead apex by simply rotating the clamping head about the centre axis.
The various aspects and features described and shown in the description may be applied separately whenever possible. These individual solutions, in particular the solutions and features described in the appended dependent claims, may be the subject of divisional patent applications.
