摘要： 720,536. Conveyers; hoppers. MOLINS, D. W., RUAU, F. F., and MOLINS MACHINE CO., Ltd. April 15, 1952 [April 5, 1951], No. 7931/51. Classes 78 (1) and 78 (3). Apparatus for discharging the contents of cigarette - trays T, Fig. 1, into the hopper 7 of cigarette-packing machine comprises a support, such as the trolley 9 or a conveyer 170, Fig. 11, on which the trays are arranged, means for sucsively moving the trays towards a position where they can be removed by a charger 3, inverted over the hopper 7 and returned to the support, and driving means set into operation by a push button and adapted to move the apparatus through a cycle in which one tray is inverted and returned and a fresh tray brought into position whereupon the apparatus stops. The charger comprises an upper limb 1, Figs. 2A and 2B, and two depending limbs 2, 3 spaced some six inches more than a tray-length apart, each of the depending limbs having tray-engaging devices 4, 5 and the whole being pivoted at 16 on a shaft 6. The movable tray cover 8 is secured to angle-iron member 18 in turn fixed to a bar 32 pivoted at each end to links 20 whose upper ends are pivoted to bearings 33 on the charger limb 1. The movement of the cover 8 away from the tray is controlled by the movement in a cam groove 23, Fig. 5, of a pin 24 of a bracket 25 secured to the bar 32. The tray engagers comprise a lever 4 shaped to engage the lower corner of the tray and pivoted at 28 to a bracket 29 on the side limb of the charger. Movement of the lever 4 to and from engagement with the corner of a tray is effected by vertical reciprocation of a rod 37 by means of a bracket 60 fixed to the rod and carrying a pin 36 engaging a slot 35 in a tail portion 34 of the lever 4. The movements of similar levers 5 into and out of steadying engagement with lugs 27 on the trays are also effected by the rods 37 in each case through a bracket 61 and a pin 38 engaging a slot in a lever 40 carrying the steadying levers 5. The cover 8 is held in traycovering position against the action of a spring 45 by means of a hook-shaped latch 46, Fig. 4, which engages a roller 49 secured to the bar 32 at about midway along its length. The latch 46 is secured to a rod 47 pivoted in several brackets 48 and bearing at one end a twoarmed lever, one end of which bears a screw 52, Fig. 3, striking an abutment 54 when the charger is over the hopper in the discharge position and the other end of which carries a spring 55 normally holding the latch in engagement with the roller 49 in all other positions. The rods 37 are moved upwards by springs 62 and are pressed downwards by rollers 57 on levers 58 pivoted at 59 to brackets on the charger upper limb. Levers 58 are pressed by rollers 64 mounted in levers 20 in turn pressed by rollers 65 on levers 75 actuated by the truckracking mechanism. The rods 37 are locked in downward (tray-engaging) position by means of double-armed levers 67, 69, Fig. 8, pivoted at 66, one arm 67 being spring pulled and the other arm 69 embracing the rod 37 and engaging the upper face of a collar 71 on the rod so as to prevent its upward movement. In operation, as the charger holding an empty tray approaches the truck (with the tray cover 8 open) an abutment 72 on the frame 14 strikes locking device 67-69 freeing the vertical rods 37 thereby releasing the empty tray from shoes 4, 5. Operation of the lever 74 moves the truck 9 forward one pitch and reverse movement of this lever effects operation of the tray-covering mechanism by causing the downward movement of a vertical rod 79 against its spring 82 to pivot levers 80 mounted on a rock shaft 77 and hence to rotate the levers 75 pivoted at 83 on the levers 80. Rotation of the levers 75 operates the tray covering, engaging and steadying mechanisms by pressure of the rollers 65 on cam face 76 of the lever 20 and hence of roller 64 on lever 58. The tray cover is locked in position by the latching device 46, 49. On operation of the button 31, the charger rotates away from the truck, the detent 72 releases the vertical rod 37 locking devices 67-69 and the rod 37 is locked thereby against upward movement so as to lock the tray-engaging means 4, 5 in engaging position. As the charger comes into position over the hopper the cover latch 46 is released by mechanism 52, 54 and the cover is guided to its open position by the slotted cams 22 under the action of springs 45 on the supporting links 20. The hopper 7, Fig. 9, is provided with a back guide 86, a front guide 87 with a transparent cover 88 and pivoted at 89 to the hopper frame, a right-hand side guide 95 and a left-hand side guide in two parts 96A, 96B pivoted and sprung at 98 so as to stand erect on pivot 97. As a tray swings over to the discharge position the two parts 96A, 96B at first move to the position shown in chain lines and later escape from contact to assume again an erect position. On the return movement of the tray the erected guide enters a slot in the side of the tray and ejects remaining cigarettes. The front guide 87 is oscillated on its pivots 89 by a crown cam 90 and a spring to assist in aligning and feeding cigarettes by lightly beating their end. In the full discharge position a plate 92 on the charger enters slot 93 and holds cam follower 91 off the cam to keep guide 87 in its open position. The truck 9 Fig. 6, is normally held against movement in either direction by detents 114 and 119. Operation of the truck-moving lever 74 pivots a plate 106 and a lever 108 pivoted thereon releases the lower detent 114. Further movement of the plate 106 pivots a pawl 103 engaging rack teeth 104 in the bar 17 so as to move the truck. A roller 127 on a pawl 121 pivoted to the plate 106 rides over a plate 126 on the tray cover controlling vertical link 79 on the truck moving upward stroke of the lever 74 but engages the plate on the downward stroke so that a fresh tray is engaged and covered after the truck has moved to bring the new tray into position. The means for rotating the charger and preventing its overrun and for balancing the charger are of the kind described in Specification 637,850. The push button 31 is rendered ineffective to connect the charger drive should there be no tray engaged in the charger. This mechanism, operated whenever the shoes 4 are in disengaged position, comprises a roller 159, Fig. 2B, on a lever 158 coupled by links 161-163 to a sector 165 which locks the operating arm 146. The one revolution clutch which, under control of the push-button 31, drives the charger-rotating mechanism, is coupled to a second one-revolution clutch also under control of the push button, to operate the truck-racking lever 74. A further embodiment is described, Figs. 11-29, in which the support to and from which empty and filled trays are respectively moved comprises a conveyer assembly. Trays T guided by rear and side guides 171, 172, Fig. 11, move forward on an endless conveyer 170, lugs 175 being provided which co-operate with notches on the tray to ensure that they are loaded facing in the required direction on the conveyer. At the end of the conveyer trays are arrested by a stop 178 on 233 in a position adjacent to rails 215 ready for lifting by an elevator. When a tray is stationary and ready for elevation, stop 178 is operative, but once elevation commences the next tray is permitted to move past stop 178 and is held by stop 233. The elevator comprises a pair of bars 179 which can be reciprocated in a vertical direction in fixed guides 181 by means of a quadrant 188, gear 187, and chain-driving gearing 183-185. The quadrant is oscillated by a rod 190 from a crank 191 mounted on a shaft 197. Each bar carries a cradle member 192 which moves upwards under the tray and securely engages it for lifting. The shaft 197 also carries a sprocket 196 driving a sprocket 297 on a cam shaft 199. Three disc cams 200, 201, 202 and a drum cam 203 mounted on this shaft control respectively a tray-locking mechanism, a tray-moving mechanism, a tray-cover closing mechanism and a tray-gripping mechanism. The traylocking mechanism comprises a vertically moving rod 226 having a shaped end adapted to engage an abutment on a charger body 245 and to hold it steady during hopper loading and is moved in and out of looking position by the movement of a cam follower 223 on the cam 200 via levers 222 and 224. The. trays are moved forward to engagement with the charger by means of a pair of channel-shaped structures 204 each supported on two parallel arms 205, 206 pivoted to a cross shaft 207 and to the machine frame respectively. One of the pairs of arms 205 carries a roller 209 engaging the cam 201 and this cam oscillates the arms 205, 206 at desired times to swing the channel structures to and fro and shift the enclosed trays accordingly. The movement of a roller on the cam 202 causes a lever 219, under control of a spring 221, to approach and recede from the charger and this lever presses against the tray cover 270 at the appropriate times so that it may be closed by means of a latch 290, Fig. 19. The tray cover 270 is fixed to two brackets 271 mounted on the charger 245 by spring and toggle linkages 274, 275, 276. A lever 213 is connected at a pivot 211 to a lever 210 having a roller 212 engaging the groove of the drum cam 203 and at the other end embraces a pin 258 on the operating levers 257, 253 and 251 of a tray gripper 265, the operating mechanism of the other tray gripper 266 being connected by a long link 261. The cigarettes are guided into the hopper by guiding means comprising an extension of the rear hopper wall, one fixed side guide a jointed guide 294 collapsed when required by a cam mechanism described in detail in Specification 720,535 and a transparent front guide which is movable up and down and oscillatable towards and away from the cigarettes under the controls of cams rotating with the charger. The operation of the apparatus is controlled by t

摘要： 716,788. Feeding webs. RUAUN, F. F., and MOLINS MACHINE CO., Ltd. March 12, 1952 [March 16, 1951], No. 6400/51. Class 100 (1). [Also in Groups VI and VIII] During feeding of a layered web 1 one or more of the layers are displaced sideways relative to the other layer or layers. Superimposed crepe paper layers 3, 4, 5, Fig. 1, of the web 1 pass separately over a web guide plate 7, the layers 3, 4 being supported by parallel rods 22. Each layer then passes between a respective pair of lateral guide rods 6, 10, Fig. 1A, where it is located laterally at each side by a collar 8 on the rod 6, the collars 8 co-acting with the layers 3, 5 being displaced along their rods, one pair in one direction and the other oppositely, relative to those co-acting with the layer 4 so that the desired relative displacements are obtained. The layers then pass together, with their relative displacements preserved by a stepped guide 23 on each side, to mechanism 100 which cuts off successive strips from the leading end of the web. Single absorbent cellulosic web layers (not shown) interleaved between the layers 3, 4, 5 may respectively be displaced with the layers 3, 5 or both remain undisplaced with the layer 4. In one modification, only the top paper layer is displaced, and in another four paper layers are used each of which is displaced relative to the others. The web is fed by intermittently-acting means 28, undue web tension being avoided by supplementary rubber-covered feeding rollers 11 partially counterbalanced by a weight 12 and bearing on the feed reel 2 of web material. The rollers 11 may be continuously rotated but, as shown, a rod 18 linked to an oscillating lever 19 associated with the means 28 intermittently rotates through a ratchet 17 a sprocket 16 driving the rollers. Specifications 462,540, 623,939, [both in Group VI], and 656,764 are referred to.

摘要： 649,467. Endless-track conveyers. MOLINS, D. W., RUAU, F. F., NICHOLS, S. A., JACKSON, N. W., WILLIAMS, H., and MOLINS MACHINE CO., Ltd. July 27, 1948, Nos. 20035 and 26892. [Class 104 (ii)] A collecting and conveying mechanism adapted to be associated with a cigarettemaking machine to receive cigarettes issuing therefrom comprises a pair of parallel tracks each defined by two L-sectioned members 25, 26 along which carriages 36 containing collecting trays are propelled in opposite directions by an endless chain conveyer 1 provided with abutments 39 which engage releasable inverted cup-shaped members 38 on the undersides of the carriages, a switching device being provided at each end of the tracks for switching the carriages from one track to the other by a reversing movement, so that the leading end of a carriage on one run becomes the trailing end on the other run. The carriages are halted temporarily by disengaging them from the chain drive at a part of the track below the discharge point of the cigarette-making machine, and at this position two carriages are arranged to be disposed endto-end with the gap between them closed by a flat surface on a member pivoted on the front end of the rear carriage, whereby cigarettes are prevented from falling between the ends of the carriages. Sprocket wheels 2, 3, Fig. 1, on vertical shafts are provided at each end of the track to guide the chain 1, and the shaft of the sprocket 3 is driven by a coaxial ratchet wheel 10, Fig. 3, and double pawl 11 at the end of a rocking-arm linked to a one end of a longitudinally reciprocating horizontal rod 16. The other end of rod 16 is pivoted to a link 17 carrying a roller 18 which is held in engagement with a cam 19 on a continuously rotating shaft 21. Each carriage 36 has eight small cylindrical studs or feet 37 with convex bases on which the carriage rides on the tracks, and an inverted cup-shaped member 38 is mounted on the end of a lever 44 pivoted centrally on the underside of the carriage. A spring 46 urges the lever 44 downwardly so that the member 38 can be put into and held in engagement with the upper end of one of a series of upstanding pegs 39 secured at intervals along the endless chain 1. The pegs are extended downwardly to provide rounded feet 51 which bear on a guide rail and support the weight of the chain. The outer rails 25, Fig. 2, of the tracks are of greater length than the inner rails 26, and join on to platforms 30, 31 which are in the same plane and have vertical outside edges 32, 33 forming continuations of the vertical limbs of the rails 25. The switching members 34, 35 each consist of a metal plate fixed to its respective platform 31 or 32 and formed with a recess in one edge to receive and engage the forward offside stud or foot 37 of an advancing carriage whereby the continuing feed of the carriage causes it to slew round on to the other track for movement in the opposite direction. When about one-third of the length of a carriage has passed the filling position a cam 47, Fig. 1, at the side of the track trips the lever 44 to disengage the inverted cup 38 from the driving peg 39 whereupon the carriage is halted during further filling, until the following carriage comes into contact with it and pushes it forward until itself halted by the cam 47. Fig. 1 shows two carriages passing from left to right below a feeding device 41 of the form described in Specification 549,877. Twin levers 52 pivoted at 53 at the leading edge of each carriage are provided at their lower ends with rollers 55 which, over a certain distance of travel engage within cam tracks 54 at the side of the apparatus, so that the upper ends of the levers bridge the gaps between the ends of the trays. In the event of a cessation in the flow of cigarettes to the collecting trays the ratchet drive of the conveyer chain 1 is tripped by means actuated by a link rod 60 which is connected to a rod 59 coupled to a two-armed lever 58 controlled by a pivoted feeler 57. The conveyer driving mechanism may incorporate the variable speed gear described in Specification 549,878, [Group XXIV]. Specifications 637,850 and 643,956, [Group XVII], also are referred to in the Provisional Specification.

摘要： 645,393. Magnetic separators. MOLINS, D. W., RUAU, F. F., HARVEY, V. P., NICHOLS, S. A., and MOLINS MACHINE CO., Ltd. July 27, 1948, No. 20036. [Class 72] In a magnetic separator having permanent magnets with a shield of non-magnetic material, the shield is pivotally attached to and covers the magnets during operation and the magnets are pivoted so that they may be removed to a non-operative position and the shield swung on its pivot for the removal of adhering magnetic material. As shown, a row of magnets 1, having a shield 6, is pivotally supported at 3 above a roller conveyer 2 carrying, for example, tobacco. When the shield has to be cleaned of magnetic material the magnet and shield are pivoted into the position shown in chain lines and, at the same time, a hopper 9 is pivoted at 10 into a position below the magnets. The shield is then swung about pivots 8 out of the magnetic field and the magnetic material allowed to fall into the hopper. In a modification, Fig. 3 (not shown), the magnets are moved substantially radially from the roller by a link system and the hopper moved into place below them, a stop on one link arresting movement of the magnets when in the desired position. The trough may be coupled to the magnets for simultaneous movement therewith or the shield and trough may be so couped that movement of the trough removes the shield from the magnets.
