| 权利要求 | 1. Loading and conveying apparatus comprising a horizontal conveyor, means to position objects on the conveyor comprising a rotary shaft mounted above and to one side of the conveyor and having a spiral land bounding a spiral groove, the latter being large enough and deep enough to partially embrace objects, means to load objects onto the conveyor and into the groove in sequence as successive portions of the groove reach the loading means, the latter comprising vertically arranged guide means above the conveyor and means for supporting objects in said guide means for releasing the same one by one to drop from the guide means onto the conveyor and into the section of the groove below the guide means, means to detect the presence of the groove section below the guide means, and means responsive to said detection means to effect actuation of said supporting means to release an object to drop from the guide means and to thereafter engage the succeeding object for supporting the same. 2. Apparatus according to claim 1 including means to reveal the absence of an object in release position in the guide means and means responsive thereto to prevent activation of the supporting and release means. 3. Apparatus according to claim 2 in which the means to reveal comprises a light beam traversing the path of the objects in the guide and photoelectric cell means aligned therewith. 4. Apparatus according to claim 1 in which the means to detect comprises switch means having rider means in position to engage the spiral land during a portion of each revolution of said shaft, and means activated by the switch means to operate the object supporting and release means. 5. Apparatus according to claim 1 in which the supporting and release means comprises a rotary helix of less than one turn aligned with the guide means above the conveyor at about the height of the objects being delivered to the conveyor, the gap in the rotary helix being coordinated with arrival of a groove section below the guide means. 6. Apparatus according to claim 5 in which a motor controlled by the detection means drives the rotary helix through one full turn at each activation of the switch means by the rider means. 7. Apparatus according to claim 5 in which the angular dimensions of the helix and its speed of rotation are a function of the height of the objects being deposited on the conveyor and the speed of rotation of the rotary shaft. 8. Apparatus according to claim 1 in which the apparatus is a bottle-loading machine and the guide means and associated controls are coordinated to the shape of the bottles. |
