Method and apparatus of adhering and building belt member

Abstract

A belt member on a supply conveyor is transferred onto a building drum from an inclined distal end portion while holding on both side edge portions in the width direction thereof. A supply conveyor places the belt member thereon and a hand device which includes holding members, extending in the feeding direction of the supply conveyor. In a state that a distal end portion of the belt member on the supply conveyor is held on a lower surface of the press plates, of the hand device, the belt member is transferred to the building drum along with a feeding operation of the supply conveyor and, at the same time, the belt member is adhered by pressing to a peripheral surface of the building drum from a distal end portion thereof while rotating the building drum along with the transfer of the belt member.

1 . An apparatus of adhering and building a belt member which transfers the belt member which embeds reinforcing cords made of metal arranged obliquely in parallel to each other in a rubber material and has at least a longitudinal distal end thereof obliquely cut along the direction of the cords onto a building drum at a belt building position from a supply portion which faces the belt building position in an opposed manner, wherein
 the apparatus includes a supply conveyor which places the belt member thereon at the supply portion for feeding the belt member toward the building position in a developed state, and a hand device for transferring and adhering the belt member on the supply conveyor to the building drum, and   the hand device includes a moving body which is movable between a position above the supply conveyor and a position above the building position, and a holding member which is elevatably supported on the moving body, includes a plate-shaped press plate extending in the moving direction and is capable of holding the belt member on the supply conveyor on a lower surface of the press plate,   the belt member is transferred to the building drum in a state that the belt member is held on the lower surface of the press plate along with the feeding operation of the supply conveyor, and   the belt member is adhered by pressing to a peripheral surface of the building drum which is rotated in synchronism with the transfer of the belt member.   
     
     
         2 . An apparatus of adhering and building a belt member according to  claim 1 , wherein the hand device is configured such that at least two holding members having press plates which are arranged parallel to the moving direction are arranged in parallel to each other, the press plates of two holding members on both sides are arranged to be held in contact with both widthwise side edge portions of the belt member, and a distance between two holding members on both sides is adjustable in conformity with a width of the belt member. 
     
     
         3 . An apparatus of adhering and building a belt member according to  claim 2 , wherein a press plate which is arranged parallel to the press plate of the holding member on the same plane is arranged at an intermediate portion between two holding members on both sides. 
     
     
         4 . An apparatus of adhering and building a belt member according to  claim 1 , wherein the holding member is configured such that magnetic attraction means which respectively include a magnet on lower end portions thereof and are extendible and retractable downwardly have the lower end portions thereof extended from a lower surface of the press plate after penetrating the press plate. 
     
     
         5 . An apparatus of adhering and building a belt member according to  claim 2 , wherein the holding member is configured such that magnetic attraction means which respectively include a magnet on lower end portions thereof and are extendible and retractable downwardly have the lower end portions thereof extended from a lower surface of the press plate after penetrating the press plate. 
     
     
         6 . An apparatus of adhering and building a belt member according to  claim 3 , wherein the holding member is configured such that magnetic attraction means which respectively include a magnet on lower end portions thereof and are extendible and retractable downwardly have the lower end portions thereof extended from a lower surface of the press plate after penetrating the press plate. 
     
     
         7 . An apparatus of adhering and building a belt member according to  claim 1 , wherein the supply conveyor has an upper surface thereof arranged to be present on the substantially same plane as an uppermost surface of a peripheral surface of the building drum at the time of feeding the belt member, and the hand device is configured to transfer the belt member on the supply conveyor to the building drum along with a feeding operation of the supply conveyor in a state that the belt member on the supply conveyor is sandwiched and held between a lower surface of the press plate and an upper surface of the conveyor. 
     
     
         8 . An apparatus of adhering and building a belt member according to  claim 2 , wherein the supply conveyor has an upper surface thereof arranged to be present on the substantially same plane as an uppermost surface of a peripheral surface of the building drum at the time of feeding the belt member, and the hand device is configured to transfer the belt member on the supply conveyor to the building drum along with a feeding operation of the supply conveyor in a state that the belt member on the supply conveyor is sandwiched and held between a lower surface of the press plate and an upper surface of the conveyor. 
     
     
         9 . An apparatus of adhering and building a belt member according to  claim 3 , wherein the supply conveyor has an upper surface thereof arranged to be present on the substantially same plane as an uppermost surface of a peripheral surface of the building drum at the time of feeding the belt member, and the hand device is configured to transfer the belt member on the supply conveyor to the building drum along with a feeding operation of the supply conveyor in a state that the belt member on the supply conveyor is sandwiched and held between a lower surface of the press plate and an upper surface of the conveyor.
