Title: An improved labelling machine
IPC: B65C9/42
Filed: 1948-03-11
Abstract: 636,445. Labelling-machines. ARMSTRONG, N. F., and TWEDDELL, J. A. March 11, 1948. Nos. 7443 and 28240. [Class 73] A machine for labelling bottles &c. is provided with a suction feed gripper actuated so that when its vacuum is decreased or destroyed owing to no label being gripped, it moves up to the label pile, and when its vacuum is restored due to a label being gripped it moves towards the labelling position. The machine is provided with a label container 3 under which a pivoted suction feed gripper 6 is mounted. A solenoid 9 operated by means of a diaphragm switch connected to the suction head of the feed gripper moves the gripper from its horizontal position to its vertical position when a label is gripped, and vice versa when the label is removed. Below the gripper 6 is a label transfer member 18 provided with four suction arms 19, adapted to be rotated by a motor by means of a friction clutch or alternatively, it may be operated by a suction-operated actuating device. An indexing disc 25 having four teeth 25a co-acts with a detent 26 to allow rotation of the member 18 through steps of 90 degrees. The detent 26 is mounted on a pivoted arm 27 adapted to be moved by a solenoid 28 operated by a micro-switch MS. At the lowest level of the transfer member two hollow arms 30 carrying suction blocks 30a are mounted on a sliding carriage 31 adapted to be reciprocated by means of a rod 33 and disc 34. A detent 36 is operated by a solenoid 38 to permit the disc 34 to rotate, the solenoid being actuated by means of a micro-switch 39. The switch 39 is closed by means of the bottle &c. to be labelled abutting against an arm 40 as it moves by on a conveyor 2. The microswitch MS is operated by means of a detent roller 41 mounted on the disc 34 which engages a lever 42 of the micro-switch as the disc rotates. In operation, a label is taken from the holder 3 by the gripper 6 and presented in the path of the transfer member 18. A bottle on the conveyer closes the micro-switch 39 which causes reciprocation of the carriage 31, and so operates micro-switch MS to actuate solenoid 28 and turn the transfer member 18 bearing the label through 90 degrees to bring the label into contact with gumming rollers 29. Meanwhile, as the carriage 31 moves forward, the suction arms 30 remove a lpreviously gummed label from the arm 19 at the owest position, and carry it forward to apply it to the bottle. A block 72 moves to engage the bottle as it is labelled, to support it. The arm 40 is held rigid during the labelling operation to prevent further bottles from interfering. The arms 30 are spread apart on the return movement of the carriage 31 by a cam plate to prevent fouling a new label being presented by the transfer member. In a modification of the device, the feed gripper is mounted for vertical reciprocation under the action of a piston, the gripper being provided with a pinion which engages a fixed rack to rotate the gripper through 180 degrees during the reciprocation, presenting it in turn to gumming rollers, and then, to a bottle held in a horizontal position.

Filed: 1960-03-07
Abstract: 880,195. Cigarette-making machines. SCHMERMUND, A. March 7, 1960 [March 16, 1959], No. 7959/60. Class 130. [Also in Group XXX] A uniform tobacco stream in a continuous rod machine is formed by depositing cut tobacco on a carrier by electrostatic precipitation. The cut tobacco is fed into a vibrating trough 2 from which it is fed into a narrower vibrating channel 18 between which and a conveyer band 40 an electrostatic field is set up to cause the tobacco particles to transfer to the band 40. The tobacco is subsequently discharged on to a second band 30 carrying the cigarette paper 33. The field may be set up by maintaining the channel 18 at a high voltage, e.g. 2000-8000 V., and an electrode 15 above the band 40 at earth potential, a second electrode 32 being maintained at such a potential to neutralize the charge on the tobacco particles to cause them to drop off the band 40 on to the band 30. As shown, however, the channel 18 and electrode 15 are at earth potential and the electrostatic field is set up by a grid 37 at high potential. The trough 2 and channel 18 are carried by springs 6, 19, mounted on insulators 41, 20, and are vibrated by electromagnets 3, 21. The distance between the channel 18 and band 40 may be adjustable and a photo-electric device 26 detects the level of tobacco in the channel and adjusts the tobacco feed accordingly.

March 11, 1959 [March 13, 1958], No. 8350/59. Classes 8(2) and 99(2). A process of insulating containers and conduits adapted to enclose fluids at low temperature comprises using an emulsion or foam formed at normal temperature by a liquid and gaseous constituent which is liquid at normal temperatures but at the temperature of usage becomes plastic or solid in which state it has thermically insulating qualities. A container 1, Fig. 1, is fed with liquefied gas through a conduit 8 and the container is surrounded by an outer enclosure 4 through which extend branch pipes 6. The insulating material is fed through the pipes 6 in the liquid form prior to filling the container. When the container is filled with the liquefied gas the fall in temperature of the material causes it to change its state to a plastic or solid. A pipe or conduit for liquified gases may be insulated in the same manner. In a modified embodiment shown in Fig. 3, the conduit 12 is insulated by the material, the outer enclosure being formed by a trench 16 covered by a facing 17. The conduit 12 is suspended by means of chains 18 from crossbeams 19. The liquid constituent of the material becomes solid or plastic at the temperature of usage while the gaseous constituent may be gaseous, liquid or solid at this temperature. Suitable liquids are water, to which is added a tension-active product, alcohols, higher hydrocarbons or suitable mixtures while nitrogen is a suitable gaseous constituent.

Abstract: 787,195. Roller mills. SOC. DE, TECHNIQUE INDUSTRIELLE. March 23, 1955 [June 14, 1954], No. 8496/55. Class 59 [Also in Group XII] In preparing coal or coal mixtures containing powdered coke or coals of different qualities prior to its introduction into a coke oven particulate coal or coal mixture is compressed by passing it between a pair of rolls having peripheral grooves arranged parallel with the roll axes. The grooves of the rolls are shown in profile in Figs. 1-3; the arrangements of the rolls being such that while there is no intermeshing in Figs. 1 and 2, the rolls in Fig. 3 intermesh in the manner of. gear teeth. One or both of the rolls may be driven and the degree of compression achieved may be varied by varying the rate of feed of uncompressed material to the rolls or by varying the separation between the rolls. The above rolls are preferably associated with a device for breaking down the compressed coal or coal mixture into a mixture containing appropriate proportions of coarse, medium and fine particle sizes - to obtain maximum density in the resultant mixture. Such a device may comprise a pair of rolls having peripheral grooves of a variety of widths in planes perpendicular to the roll axes so that the compressed coal is cut into strips of a variety of widths. As shown in Fig. 6 the rolls are mounted at the base of the hopper 7 of the coal charging car of a coke oven battery, the rolls 8 compressing the coal from the hopper 7 and the rolls 9 breaking down the coal into particles of a desired size. The rolls 8 and 9 are rotated at high peripheral speed so that coal from the hopper 7 is eventually discharged downwardly at considerable speed into the coke oven 10.
