Title: Apparatus for feeding and inserting individual articles into holders of a continuously travelling conveyor means of a carton packing machine
Inventor: SCHUSTER WILHELM
IPC: B65B57/14
Filed: 1969-07-21
Abstract: 1278700 Transferring articles between endless conveyers INDUSTRIE-WERKE KARLSRUHE AG 21 July 1969 [20 July 1968] 36489/69 Heading B8A In apparatus for supplying and inserting individual articles 1 into holders 19 of a continuously travelling conveyer 20 of a carton packing machine, with a feed device 2 conveying the articles 1 continuously from a filling and closing machine (not shown) to a receiving point of the conveyer 20 a transfer device 16 moves in synchronism with the conveyer means 20 and supplies the articles 1 to the latter, and a pusher member 10 conveys the articles 1 from the end of the feed device 2 into the transfer device 16. Actuation of the member 10 is controlled by a switching device 5 dependently upon the presence of the individual articles at the end of the feed device, and a detent element 7 which permits the actuation only when a member 4 is displaced by the passage of an article 1. The member 4 closes the switch 5 which controls the rotation of a cam 7. The latter has a section 9 for operating a switch 6 actuating the member 10. The latter is driven by amotor 11. A cam disc 14 on the motor shaft operates a switch 13 after return of the member 10 to its inoperative position, thereby stopping the member 10. In Fig. 4, a plurality of belts 2 deliver articles 1 to a transfer position in which they may be deflected simultaneously by pushers 31 to a belt 38. Absence of any one or more of the articles on a respective belt 2 prior to the point of transfer is detected by a photoelectric device (21) (Fig. 3, not shown). This causes the articles which are present, to be deflected to a container (not shown) instead of being transferred to the belt 38. When a full complement of articles 1 arrives at the transfer position, a photo-electric device (23) is energized, and this causes actuation of a clutch 24 in the drive of the pushers 31. Spacing of the articles on the belt 38 is controlled by a flighted conveyer belt 33. The articles 1 are thereby fed into pockets of a conveyer 20.

Title: Improvements in or relating to tying apparatus
IPC: B65B51/08
Filed: 1965-08-25
Abstract: 1,115,531. Bag neck tying apparatus. ROYAL INDUSTRIES Inc. 25 Aug., 1965 [25 Jan., 1965], No. 36572/65. Headings B8C and B8F. [Also in Division B3] An apparatus for fixing a tag 200 to a bag by means of a ribbon-shaped tie 16 comprises means for positioning the tag so that the ribbon can be bent into a U-shape about the bag and the tag, a knife blade 56 for severing the ribbon from its supply and a rotary twisting head 54 for winding its free ends about each other to close the bag. The bag is manually inserted into a V-shaped throat 13 and the ribbon 16 is fed from a supply reel 14 by a feeding disc 40 and an idler 114 through a tube 63 to the twisting head at 54. The ribbon 16 is preferably soft wire coated with paper or plastics. When the bag is inserted in the throat it engages a trigger arm 84 and pivots it clockwise against the bias of a coil spring. This action moves a latch 90 to the right against the bias of a tension spring 96, pivoting an arm 32 causing a latch 32B to disengage from a stop 28 on the driven member of a clutch 26. The disengagement causes a programme plate 35, comprising a segmented bevel gear 36, the feed disc 40 and a cam 52, to rotate through one revolution. The feeding disc 40, which has a segmented portion 40a supplies ribbon to the twisting head 54. The cam 52 also rotates and when an arm 104A disengages from the cam, a tension spring 111 causing an arm 104 to pivot counterclockwise about its fulcrum 106. A link 108, which is pivotally connected to the arm 104 and a ribbon folding finger 98 therefor, moves to the right causing the finger 98 to force the ribbon 16 around the bag into a U-shape. The segmented gear 36 now engages a pinion 74 on the end of a shaft 60. The ribbon 16 is severed by the knife blade 56, as the head 54 rotates. The free-ends of the U-shaped ribbon enter slots 55A, 55B in the head 54 and are forced against the back of the head 54 by a guide 81 and twisted together. The tag has an aperture and is positioned on a support (202), Fig. 5 (not shown), so that when the ribbon is fed from the spool 14, the ribbon passes through the aperture. The support (202), which is of generally L-shape, is arranged adjacent the inner end of the throat 13 and has a spring clip (203) along one side to hold the tag 200 in position with its free edge held relatively loosely. The positioning and feeding of tags 200 to the support 202 may be manual or automatic.

Title: Improvements in and relating to electric control systems
Inventor: COXON THOMAS
IPC: B21B37/46
Filed: 1954-12-24
Abstract: 820,561. Automatic tension control systems. ENGLISH ELECTRIC CO. Ltd. Dec. 16, 1955 [Dec. 24, 1954], No. 37390/54. Class 38 (4). In a control system one or other of two electric control quantities may be selected by a switch to control a regulator and the difference between the two electric control quantities automatically adjusts the quantity not selected to maintain it equal to the selected control quantity in readiness for a smooth changeover. The tension in a loop of material between successive rolls of a strip rolling mill is detected by an auxiliary roller associated with an electrical pick-off which serves to energize a control winding 36b, Fig. 3, of a magnetic amplifier 36. To obtain automatic tension control, switches 41, 35, 48 are closed and the desired tension is set by a manually operated potentiometer 27 which determines the energization of a reference control winding 36a of magnetic amplifier 36. Deviations in tension from the desired value then result in an output from magnetic amplifier 36 to energize control windings 24b, 25b of magnetic amplifiers (not shown) respectively associated with the field energization of booster generators in the supply to separate electric motors driving the rolls so that the supply voltage to one is increased and that to the other decreased to correct the deviation. Under these conditions the current in a resistor 32, and therefore in a resistor 33, is maintained equal to the current in a resistor 39, and therefore in windings 24b, 25b, by opposing control windings 43a, 43b of a magnetic amplifier 43 so that any difference is corrected by an output from magnetic amplifier 43 which runs a motor 31 to adjust a potentiometer 28. This ensures smooth changeover from automatic to manual control if switches 42, 34, 47 are closed and switches 41, 35, 48 are opened at any time, since the energization of further control windings 24a, 25a of the magnetic amplifiers associated with the booster generators is initially the same as that of control windings 24b, 25b when automatic control ceased. Tension may then be adjusted manually by operation of potentiometer 27 controlling the energization of control windings 24a, 25a and under these conditions magnetic amplifier 43 is associated with a motor 30 adjusting a potentiometer 26 so that equality of currents in a resistor 40 and windings 24a, 25a is maintained in readiness for return to automatic control.
