Abstract
A riveting press wherein the reciprocable ram of the upper tool can be rotated by a stepping motor to transmit torque to an article holding device which is reciprocable independently of the ram to pick up randomly oriented articles from a transferring device. The latter accepts successive randomly oriented articles from a chute and carries a sensor which interrupts rotation of the article and of the holding device when its follower detects a marker on the article. An adjustable selector switch or a computer is provided to induce the motor to turn the holding device and the article therein to a final angular position prior to application of the article to a garment.
Claims28
Apparatus for orienting discrete articles of the type including buttons, portions of rivets and other notions wherein the articles are provided with orientation indicating markers, comprising a rotary article holding device having means for non-rotatably engaging one article at a time;
- stepping motor means operative to rotate said holding device;
- a source of randomly oriented articles;
- a device for transferring discrete articles from said source to said holding device;
- sensor means provided on at least one of said devices to monitor the position of an article by scanning the article for the respective marker and including means for transmitting first signals enabling said motor means to rotate said holding device, while the article having the scanned marker is held by said engaging means, until the holding device and such article assume a first predetermined angular position;
- and selector means including means for transmitting to said motor means second signals to rotate said holding device and the article held by said engaging means from said first angular position to a predetermined second angular position.
