| 摘要 | A transfer means including a work gripping arm for moving the work to selected positions, the transfer means having stop or positioning shock absorbers. There can be shock absorbers for either direction of movement, and there can be a plurality of settable stops and adjustable positioners so that various selected positions can be achieved. | ||||||
| 权利要求 | 1. In a transfer means for moving a reaching arm to a preselected position, the combination including frame means, carriage means carrying said reaching arm, said carriage means being vertically movable relative to said frame means, arm means having said reaching arm thereon, said arm means being horizontally movably mounted on said carriage means and movable relative thereto, positioning means including shock absorbing means mounted on said arm means and movable therewith, a plurality of stop means on said carriage means, said positioning means and stop means being movable relative to each other as said arm means moves, said positioning means contacting the one of said plurality of stop means which is in the line of movement of said positioning means and shock absorbing means for stopping said arm means at a preselected position, and means for transversely moving said positioning means and shock absorbing means relative to said stop means so as to preselect the one of said stop means to be contacted by the positioning and shock absorbing means. 1. In a transfer means for moving a reaching arm to a preselected position, the combination including frame means, carriage means carrying said reaching arm, said carriage means being vertically movable relative to said frame means, arm means having said reaching arm thereon, said arm means being horizontally movably mounted on said carriage means and movable relative thereto, positioning means including shock absorbing means mounted on said arm means and movable therewith, a plurality of stop means on said carriage means, said positioning means and stop means being movable relative to each other as said arm means moves, said positioning means contacting the one of said plurality of stop means which is in the line of movement of said positioning means and shock absorbing means for stopping said arm means at a preselected position, and means for transversely moving said positioning means and shock absorbing means relative to said stop means so as to preselect the one of said stop means to be contacted by the positioning and shock absorbing means. 2. A transfer means as claimed in claim 1 wherein said positioning means and shock absorbing means are mounted on an arm arcuately movable relative to said plurality of stop means. 3. A transfer means as claimed in claim 1 wherein said positioning means and shock absorbing means comprises an integral shock absorbing means and including an arm positioning plunger which is contactable with said stop means as said arm means is moved relative to said carriage means, said plunger being fluid activated to provide shock absorbing force and stopping movement of said arm means relative to said carriage means after said plunger contacts said stop means, and fluid operated signal means operated by said plunger means when the plunger means reaches the end of its travel and stops movement of said arm means relative to said carriage Means. 4. A transfer means as claimed in claim 1 including means for rotating said carriage means in a plane substantially parallel to said arm means. 5. A transfer means as claimed in claim 1 and having a second set of a plurality of adjustable stop means on said carriage means and positioning means including shock absorbing means mounted on said arm means for stopping movement of said arm means relative to said carriage means when moved in the opposite direction. 6. A transfer means as claimed in claim 1 and also including a plurality of adjustable vertical stop means mounted on a vertical axis relative to said arm means and vertical positioning means including shock absorbing means mounted on said carriage means and movable vertically therewith for contacting one of said plurality of vertical stop means which is in the line of movement of said vertical positioning means for stopping vertical movement of said carriage means, and means for transversely moving said vertical positioning means and shock absorbing means relative to said vertical stop means so as to preselect the one of said vertical stop means to be contacted by the vertical positioning and shock absorbing means. 7. In a transfer means as claimed in claim 4 wherein said means for rotating said carriage means includes an endless drive chain means and a pair of positioning means connected thereto, one of said positioning means cooperating with a stop means for stopping movement of said chain means in one direction and the other of said positioning means cooperating with a stop means for stopping said chain means in the other direction. |
