Abstract
In a tire vulcanizing machine--comprising an element for moving the tire and a mold with several segments carrying mold sections that can move radially--the top section of the mold is held by said element, which can move axially and angularly to occupy one position in which it can collect the untreated tire, one position in which it places the tire into the mold and one position in which it unloads the vulcanized tire onto devices which collect and remove it; element comprises devices which engage the upper rim of said tire on the top section of the mold in the collection position; devices for centering said rim with respect to the top section of the mold are also provided.
Claims16
A device for vulcanizing tires comprising:
- moving element means for moving a tire to be vulcanized from a collection location to a mold location and for moving a vulcanized tire from the mold location to a removal location;
- a top mold section connected to said moving element means;
- collection centering means for collecting the tires to be vulcanized and centering a rim of the tire to be vulcanized;
- grasping means connected to said moving element means for retaining the rim against the top mold section after the interior rim edge has been centered and for releasing the rim from the top mold section prior to vulcanizing the tire, said grasping means including oscillatable elements connected to said moving element means and connected to grasping elements for moving the grasping elements between a grasped position and a disengaged position;
- radially movable mold segments positioned at said mold location, said segments movable radially toward the tire to be vulcanized to be positioned about the tire to be vulcanized upon the tire to vulcanized being moved from the collection location to the mold location;
- flexible chamber means positionable within the tire to be vulcanized after said radially movable mold parts are positioned about the tire to be vulcanized to maintain the tire to be vulcanized in a centered position with respect to the top mold section and the radially movable mold parts;
- and, piston means for moving said grasping means after said grasping element have been disengaged from the tire to be vulcanized from within the mold sections to a location above said top mold section after the flexible chamber means centers the tire to be vulcanized.

A device for vulcanizing tires comprising:
- moving element means for moving a tire to be vulcanized from a collection location to a mold location and for moving a vulcanized tire from the mold locationto a removal location;
- a top mold section connected to said moving element means, said top mold section having a centering lip for engaging an interior edge of a tire;
- collection centering means for collecting the tire to be vulcanized and centering a rim of the tire to be vulcanized and for moving an interior rim edge of the tire to be vulcanized into engagement with the centering lip of the top mold section;
- grasping means connected to said moving element means for retaining the rim against the top mold section after the interior rim edge has been centered and has engaged with said centering lip and for releasing the rim from the top mold section prior to vulcanizing the tire, said grasping means including oscillatable elements connected to said moving element means and connected to grasping elements for moving the grasping elements between a grasped position and a disengaged position;
- radially movable mold segments positioned at said mold location, said segments movable radially about the tire to be vulcanized upon the tire being moved from the collection location to the mold location;
- flexible chamber means positionable within the tire to be vulcanized after said radially movable mold parts are positioned about the tire to be vulcanized to maintain the tire to be vulcanized in a centered position with respect to the top mold section and the radially movable mold parts;
- piston means connected to said grasping means for removing said grasping means from adjacent the tire to be vulcanized after said grasping elements have been disengaged after the flexible chamber means centers the tire to be vulcanized.
