BREAKAGE PREVENTION MECHANISM OF TRANSFER APPARATUS AND TRANSFER APPARATUS USING THEREOF

摘要

A breakage prevention mechanism is configured to prevent deformation or breakage of a crossbar and transfer the work even in the condition where a pair of left and right arm supporting the both end of the cross bar is displaced beyond assumption. The breakage prevention mechanism is equipped with a pair of arms which is synchronized and moves approximately parallel, and a crossbar bridged between the top end of the arms. Both end of the crossbar and the arm are connected pivotably around two axis. Both end of the crossbar are configured to be slidable against the arm in X axis direction. The plunger is placed between both end of the crossbar and arm, in which protects the crossbar by restraining the pivoting and the sliding of both in the normal condition and releasing the restraint when the unintended force is given.

主权项

1. A crossbar system transfer apparatus configured to carry a work in or out of a press machine, comprising:
a crossbar provided with a work holder that holds the work; a pair of transferring members that supports the crossbar; a connection member connected between the crossbar and one of the pair of transferring members; and a shaft member being held by both of the crossbar and the connection member, wherein the crossbar pivots around the shaft member relative to the connection member, and one of the crossbar and the connection member slides on and along a surface of the shaft member.
