Abstract: 1,241,307. Conveyers. RAPISTAN Inc. 4 Nov., 1968 [3 Nov., 1967], No. 52218/68. Heading B8A. Conveyer apparatus 10 has a device 16 for turning selected cartons while on a conveyer 12, prior to their transfer to a conveyer 14, the selected cartons then being at right angles to the remaining cartons. When transferred to a pallet the cartons are thus arranged for forming into interlocking layers. The device 16 comprises an endless chain 44 having link flanges 48a which straddle a guide rail 50 such that, when the device 16 is to be inactive, the upper pass of the chain 44 travels just beneath the plane of conveyer surface 12a, Fig. 6. For turning a carton, the chain 44 is raised above the surface 12a by operation of a fluid cylinder 62 which raises the guide rail 50. Cartons which are engaged by the device 16 are also engaged by a driven chain 90 which prevents over-rotation of the cartons. In passing on to the conveyer 14, cartons which have not been turned by the device 16 are engaged by an edge 120<SP>1</SP> of a guard rail 120 and move into longitudinal alignment with the conveyer 14. The apparatus is controlled by a memory system which activates the device 16 by carton detecting means 20 and deactivates the device 16 by detecting means 22. Figs. 9a-9d (not shown) schematically indicate the operation of the apparatus. The rollers of the conveyer 12 may be belt-driven or the conveyer may be of the gravity type. In a modification, Fig. 8 (not shown), the turning device (16) is located immediately adjacent the conveyer (14) and a driven chain (222) replaces a guard rail 122 of the first embodiment.

IPC: B65B35/56
Filed: 1967-11-17
Abstract: 1,206,551. Packaging articles. A. K. LITTWIN. 17 Nov., 1967 [12 Jan., 1967], No. 52478/67. Heading B8C. [Also in Division G1] Apparatus for packaging magnetizable articles in a box comprises an A.C. circuit for energizing two magnetic elements which align the articles as they are fed into the box. A conveyer 42, whose height can be adjusted by screws 55 for different box heights, has cleats 43 for engaging and moving boxes 44 placed on the conveyer between sidewalls 47 which may be adjusted for different box sizes so as to frictionally retard the movement of a box. The box is moved in the direction 46 and interrupts the beam of a photo-cell system 57, thereby causing the conveyer to stop when the box reaches the filling position 48 between flanges 52 and the poles 49, 50 of an electromagnet 51. A timing relay, energized as a result of the photo-cell signal, now causes article feed by a bowl feeder 58 of known kind from which the articles e.g. tubes used in hypodermic needles, emerge at an opening 60 and enter a transfer trough 61. Finally, the articles move along a spout 62 and drop into the box 44. All three components 58, 61, 62 of the feed system are vibrated to assist the flow of articles. The spout 62 also traverses back and forth above the box so that articles are distributed along its length. Since they are between the poles of magnet 51, the articles will be aligned lengthwise across the box. As the box is filled, the presence of the articles increases the reactance of the magnetizing coils, and when a preset value is reached a relay is de-energized causing article feeding to stop and the magnet to be de-energized. It also causes the start of the conveyer motor and discharge of the box between flanges 54. Simultaneously, a new box is brought to the filling position. Since the magnet 51 produces an alternating field, when the magnet is de-energized, the decreasing field demagnetizes the articles before the filled box is discharged.

Abstract: 1408283 Measuring the movement of a worktable FERRANTI Ltd 20 Nov 1973 [21 Nov 1972] 53779/72 Heading G1A In an apparatus for measuring the movement of a work-table 2 employing a first measuring system 5, comprising a roller 6 which is moved when the table moves causing a grating 9 to move, and thereby creating a "moivre fringe effect" with an index grating in a measuring head 11 containing a light source and photo-cells, the output signal of the first measuring system is corrected by a second measuring system. The second measuring system comprises, for example, a number of permanent magnets and cam surfaces 17 spaced at predetermined positions along the periphery of the work-table so as to co-operate with a transducer 14 and a series of switches 18, 19, 20 and 21 and produce a different signal each time the table reaches a different predetermined position, the secondary signal being provided by for example, a high frequency A.C. bridge 15 wound on an "E" shaped core. The secondary signal is used to reset the value on a bi-directional counter (22), Fig. 3 (not shown) that is fed from the measuring head 11, to a correct value provided by a logic system (24) supplied by the switches 18, 19, 20 and 21. Thus in the preferred embodiment movement of the table causes the bi-directional counter 22 to count up or down in dependence upon the direction of movement of the work-table, but every time one of the predetermined positions is passed the value on the bi-directional counter is reset, if necessary, to the correct value thereby mitigating any errors due to slipping of the roller 6 on the work-table 2. The description also refers briefly to possible applications of the invention to a reciprocating elongated work-table and to analogue or hybrid correction systems.
