Abstract: 1,028,679. Storing articles. TRIAX CO. Aug. 4, 1964 [July 31, 1963], No. 30838/64. Heading B8E. Automatically operated warehousing apparatus comprises a storage frame 10, Fig. 1, having load support means 12, 12<SP>1</SP>, and a load carrier 15 for transporting a load from loading stations 13, 13<SP>1</SP> to the support means and having a platform 80, Fig. 5, adapted for movement laterally of the carrier 15 for transferring a load between the carrier and the support means 12, 12<SP>1</SP>, the carrier being provided with photo-electric cells 92, 93, 94 and light sources 95, 96, 97 for automatically stopping the platform 80 if a load exceeding a predetermined size breaks a selected one of the light beams. The carrier 15 is movable vertically and horizontally in an aisle 11 disposed between the load support means 12, 12<SP>1</SP> which are formed as channels 27, Fig. 2, for supporting pallets P on which the loads are transported; different heights of load may be allocated to designated parts of the frame 10, e.g. low loads to parts L . . . L, medium loads to parts M . . . M and high loads to parts H. The carrier 15 moves horizontally along top and bottom rails 32, 34, having racks 33, 35, wheels 41 engaging the rail 34 and pinions 45 and 47 which are driven by an electric motor 49 through a belt drive 50 and a shaft 48 engaging the racks 33 and 35. Back-up rollers 51, 52 and idler pinions 53, 54 with associated back-up idler rollers 56, 57 are provided. The carrier has a frame 40 mounted on which is a vertically movable frame 60 engaging masts 42, 43 of the frame 40 by rollers 59, Fig. 4, the mast 43 having a rack 61 engaged by a pinion 63 driven by an electric motor 62. The platform 80 is mounted for limited vertical movement on a plurality of fluid-operated jacks 81 carried by a laterally moving extractor unit 65 mounted on rollers 70, 71 within the frame 60. The extractor unit is moved by pinions 73 driven by an electric motor 74 through a belt drive 75 and engaging a rack 72, back-up rollers 76 being provided. Photo-electric cells and light sources are provided on both sides of the frame 60 which has a control console 100 carrying a plurality of manual selector switches controlling the automatic operation of the apparatus through an electric circuit, Fig. 6 (not shown). When not in use the carrier is normally positioned at a start-position adjacent the loading stations 13, 13<SP>1</SP>. If a load to be stored has been positioned, e.g. by a lift truck, on one of the stations 13, 13<SP>1</SP> and the control console switches suitably set, the load will automatically be carried to the preselected load support means 12 or 12<SP>1</SP> of the frame 10. Loads above a maximum height will break the light beam associated with the highest photo-electric cell 94 when the load is being transferred from the loading station to the carrier by the platform 80 which will stop then reverse and return the load to the loading station. Low and medium size loads are similarly sensed for height as they are being transferred from the carrier to the load support means and if rejected the carrier returns to the start position with the load still on the platform 80.
