Abstract
The invention concerns a device wherein the bars (13) are arranged in bulk in the container (5). The mobile frame (17) of the grasping mechanism (14) moves forward such that the jaw (24) can seize a bar by its middle part and remove it in position (13a) while the trolleys (37) move away from the rail (36) so that the rollers slide on the rods (43), gradually lift the whole bar and bring it to rest on the receptacle (16). The shaft (49) is then driven in rotation so that the racks (47) and the support plate segments (46), which form the receptacle (16), move upwards and the bar (13) drops in the supply channel (8) where it is hooked to the bar clamp of the bar-pusher which drives it axially into the turning center control members.
Claims18
A device for supplying a machine tool, in particular an automatic lathe, with bars to be machined, comprising a feed channel aligned on the axis of the machine tool and means for introducing bars into this channel one by one, wherein the said means comprise
- a fixed container able to contain a stock of bars stacked in bulk in the longitudinal direction, having a straight top longitudinal edge,
- a receptacle adjacent to the said top edge of the container and extending above the feed channel, said receptacle being displaceable to uncover the feed channel,
- at least one repetitive-action gripping mechanism, disposed so as to grip, in the container, at least a portion of a bar to be introduced into the channel and to pull it into a given position situated above the receptacle,
- at least one alignment mechanism having at least one member which moves in the longitudinal direction and progressively withdraws from the container all the bar gripped by the gripping mechanism, so as to place all the bar in the receptacle, and
- control means which cause the said bar to be released by the gripping mechanism, to drop into the bottom of the receptacle and then into the feed channel.
