HOPPER CONTROL MECHANISMS z'chard rewzzzrg HoPPER CONTROL MECHANISMS Richard Creuzburg, Hamburg-Bergedorf, Germany, assignor to Kurt Korber & Co. K. G., Hamburg-Bergedorf, Germany Application October 7, 1955, Serial No. 539,244
Claims priority, application Germany October 12, 1954 7 Claims. (Cl. 214-17) The present invention relates to improvements in hopper control mechanisms, and more particularly to a hopper feed mechanism for cigarettes and similar elongated elements. y
One object of the invention is to provide a hopper feed mechanism in which the articles such as cigarettes and the like are evenly distributed throughout the hopper magazine in such a manner that they will be deposited in the hopper uniformly with their longitudinal axis extending in the same direction.
Another object is to provide a hopper feed control mechanism which will automatically cut off the rhopper feed when the articles or material in the hopper reaches a predetermined height. l
Another object is to provide a hopper feed mechanism having a distributing wheel provided with a series of radially arranged circumferentially spaced pegs which are projected during 180 rotational movement of the wheel and retracted for `substantially the remainder of the rotational movement such that the articles or material such as cigarettes fed to the hopper will be picked up by the projected pin and moved toward the center of the hopper in a direction upwardly so that they may slide off the pins by gravity and be evenly distributed across the entire area of the hopper.
Another object is to provide a hopper feed mechanism for cigarettes and the like having means for maintaining the hopperlevel constant which includes an endless conveyor extending across the top of the hopper having a series of teeth which engage the uppermost cigarettes or the like and remove them from the hopper at the top thereof a small instant before the cut-off member has moved upwardly sutiiciently to interrupt operation of the feed mechanism.
Hitherto, in the manufacture of cigarettes it has been customary to remove the cigarettes from the ycigarette machine and deposit the same in a container or hopper magazine so that they may be supplied to other operating mechanisms for cigarettes such as for instance, packing machines or machines for applying lter tips to the ends of the cigarettes. In order to obtain maximum production and to increase the output, it is advisable to conlnect the cigarette machine with the packaging or filter tip applying mechanisms by means of suitable automatic conveyors. Also, in prior art devices cigarettes have been delivered from the cigarette machine and dropped into suitable magazines from the top o-f the magazine.
The above prior art devices are disadvantageous due to the fact that considerable time is lost and required to handle cigarettes manually, and in theA prior devices where the cigarettes are conveyed to the top of a hopper or magazine they fall a considerable distance which causes tobacco to be dislodged from the ends and frequently, the cigarettes falling at random havea tendency to more readily clog the delivery opening and thus prevent the normal uniform feeding and delivery of the cigarettes atent fbice to other machines, such as wrapping and filter applying apparatus.
The present invention eliminates the above-mentloned disadvantages and feeds the cigarettes uniformly without dropping the same from a conveyor, and permits 'the cigarettes to be fed to the hopper in such a manner that the height is maintained substantially constant lthus insuring continuous ow or discharge from the hopper at a uniform rate of speed. In addition the cigarettes when delivered to the hopper are fed upwardly toward ,the surface of the stack and in addition urges ythe-cigarettes in a horizontal direction across the hopper such that the hopper will be filled with the level of thecigarettes substantially horizontal along thetop portions thereof in the hopper. n
Other objects and advantages of the invention will become apparent during the course of the f ollowing'description of the accompanying drawing wherein:
Figure 1 is a vertical cross-sectional view through a hopper magazine showing the feed mechanism and illustrating the various mechanisms and controls for the feed mechanism, and
Figure 2 is a fragmentary vertical cross-sectional v iew showing a modified form of the invention in which three distributing wheels are employed. v
In the drawings, and more in detail, attention is rs directed to Figure l wherein the reference character 5 will generally be employed to designate a hopper or magazine for cigarettes or similar items and saidhopper includes a pair of side walls 6, a downwardly sloping wall 7 connecting the side walls 6 and a downwardlysloping side wall 8 likewise connecting the walls 6, and said sloping walls 7 and 8 converge toward a discharge opening 9 which may be fitted with a suitable discharge chute for conveying cigarettes or the like to a cigarette wrapping machine or to a machine for applying filter tips.
The downwardly sloping wall 8 connects with an arcuately curved portion 10 which extends betweenthe side walls 6 and extending downwardly between the side walls 6 is a wall 11 which has its lower end arranged in spaced relation from the end of the wall- 10, thus' providing a space for filling the hopper with material as cigarettes or the like,
An endless conveyor generally designated 12 includes a pair of sheaves 13 arranged in spaced relation, and one of which is shown presented to the space between Vthe arcuately curved portion 10 and the end wall 11. An endless belt 14 is trained over the pulleys 13 and is'provided with a series of spaced llights 15 which are adapted to receive cigarettes or the like 16 and convey the same upwardly through the opening between the walls 10 and 11 and into the hopper 5.
Rotatably mounted within the hopper 5 and `arrangedadjacent the opening between the walls 10 and 114 is a rotary drum generally designated 17 which forms la lsocalled cell wheel for conveying cigarettes through the opening between the 4walls 10 and 11fand horizontally acrossrthe conveyor. The cell wheel 17 includes'a drum 18 which is rotatably mounted on a shaft 20 which is secured tc the side walls 6 of the hopper in anyapproved manner. Secured to the shaft 20 is an eccentric disc 21 having a circular track 22. A series of circumferentially spaced retractable pins 23 are vslidably lmounted'in the drum 17 in suitable openings therein, and'said pins y23! are provided with transversely extending guide pins 24 which are arranged to be received in the'circular trackway 22 such that when the drum 17 is rotated in the direction of the arrow, the pins 23 will engage the cigarettes fed between the wall portions 10 and 11 by the conveyor 12 `and carry said cigarettes in a horizontal direction tothree sets of pins 23 which would be guided by three such - 17 and wall 10. One end of the drum 17 is provided with a pulley 25 which is adapted to be driven in a manner which hereinafter be fully described so that the drum 17 will rotate in the direction of the arrow and the pins 23 will be projected during their travel through their lower portion of the drum 17, and will be retracted during their travel through the upper portion of the drum.
Mounted between the side walls 6 adjacent the upper end thereof is a shaft 26 to which is pivotally secured a pair ofbars 27 which have their outer ends connected by means of a shaft 28. Conveyor rollers 3f) and 31 are mounted on the shafts 2,6 and 28, and an endless belt 32 is trained thereover for rotation in the direction of the arrow. A series of teeth 33 are arranged in spaced relation on the endless belt 32, and said teeth are adapted to engage surplus cigarettes and convey them from the hopper when the hopper fills above a predetermined height and thus maintain the height of the cigarettes in the hopper constant. A pulley is secured to one end of the conveyor roller 30 in any approved manner.
Secured to the wall 11 adjacent the upper end is a pair of inwardly projecting lugs 36 to which is pivoted as at 37 a control bar 38 which is provided with an elongated central slot (not shown) for accommodating the passage of the teeth 33. The bar 38 is urged upwardly by the cigarettes in the hopper 6 to control the feed of cigarettes to the hopper.
In order to drive the conveyor 12, cell wheel 17 and endless conveyor 32 there is provided an electric motor 39 which is connected in circuit with a source of electrical energy supplied through lines 40. Also in the circuit 41 of the motor 39 is a normally closed switch 42 which is adapted to be actuated by means of a relay solenoid 43. The solenoid 43 is in circuit with a source of electrical energy supplied to lines 44, and said lines are connected to a circuit including lines 45 and 46. The line 45 is connected to a contact point 47 on the end of the control bar 38, and said contact is adapted to engage a contact member 43 connected to the line 46 when the cigarettes in the hopper 6 rise to a predetermined height and cause the control bar 38 to move upwardly. The contact 48 is mounted on the end of an arm 50 which is an extension of the bars 27 and thus, said contact and arm will be raised and lowered depending upon the position of the control bar 38. The sloping wall 7 is provided with a slot to permit the control bar 38 to move downwardly away from the conveyor 32, but the upper end of the hopper 7 engages the arm 50 and prevents the conveyor 32 from swinging downwardly on top of the cigarettes below a predetermined level.
The electric motor 39 has its armature shaft 51 connected to a series of reduction gear units 52, 53 and 54 which are provided with suitable control handles and outlet shafts fitted with pulleys 55, 56 and 57. The pulley 55 is drivingly connected to a pulley on the convey-or roller 13 by means of a drive belt 60 and the pulley 56 is connected to the pulley 25 on the drum 17 by means of a drive belt 61. Similarly, the pulley 57 is drivingly connected to a pulley on the roller 30 by means of a drive belt 62. Thus, when the motor 39 is energized the conveyor 12 will be operated, the cell wheel will rotate to feed cigarettes into the hopper and the endless conveyor 32 will be operated such that when the control bar 38 is partially raised so that the pins 33 pass through the slots therein to remove excess cigarettes just prior to engagement with the contacts 47 and 48. The cigarette level in the hopper will in this manner be maintained constant. When the cigarettes move beyond the upper level limit in the hopper the control bar 38 likewise movesupwardly to engage the contacts 47 and 48. When .4 this occurs, the relay 43 is energized and the normally closed switch 42 is opened, thereby breaking the circuit through the power lines 40 to the motor 39. When the motor 39 is de-energized, rotation of the shaft 51 is arrested which stops the conveyor 12, cell wheel 17 and conveyor 32. When the level of the cigarettes in the hopper drops from normal discharge through the outlet 9 the contacts 47 and 48 are separated, which causes the relay 43 to be de-energized so that the spring pressed plunger or armature thereof may again close the switch 42.
la the modified form of the invention shown in Figure 2 the hopper 5 is substantially the same as before, and includes a pair of side walls 6' having sloping bottom walls 7. The end wall 11 is substantially the same as before and is spaced from the end of the arcuately curved wall An endless conveyor generally designated 12' includes a pair of rollers 13 in spaced relation having a conveyor belt 14 for feeding cigarettes 16' through the space between the ends of the arcuately curved wall 10 and the wall 11.
Mounted in the hopper 6 is a series of shafts 18 which are arranged in superposed relation, and said shafts are adapted to rotatably support cell wheels generally designated 17. The cell wheels include drums 20 having a series of retractable and projectable pins 21' which are operated in substantially the same manner as described in connection with the form of the invention shown in Figure l, except that the lowermost cell wheel 20 is provided on one end with gear wheels 70', 71 and 72 which are adapted to be inter-driven by means of gear wheels 73 and 74' mounted on suitable pivot pins 76 and 77 supported on the hopper on one of the side walls 6 thereof. The cell wheels are adapted to be driven by an electric motor 39 which has a power shaft 51 connected to reduction gear units 53' and 54'. The reduction gear unit 53' is provided with a driving belt 61 adapted to drivingly engage a pulley on one end of the lowermost cell wheel 17' so as to drive the superposed drive wheels at the same speed. Thus, cigarettes 16 fed to the hopper are moved upwardly and across the hopper 5 by the cell wheels 17', and when the control bar 38' is moved upwardly about its pivot 37 contacts on the end thereof will engage a contact carried by the extension of the side bars 27 and energize the control circuit including lines 45 and 46' which are in circuit with a source of electrical energy supplied through power lines 40 for supplying current to the electric motor 39.
The endless conveyor 32' is the same as before and is mounted on a pulley 26' or roller rotatably mounted on the arm 27. The shaft 30 is secured to the walls 6 of the hopper as before, and the endless conveyor 32 is provided with cigarette engaging pins 33'. The endless conveyor 33 is driven from the reduction gear box 54 by means of an endless belt 62 which is trained over a pulley 63' on the reduction gear box and the roller 30 of the conveyor 32.
Thus, cigarettes conveyed to the hopper 6' by the conveyor 14 from a cigarette making machine are moved upwardly and across the hopper 6' to uniformly till the hopper and as the cigarettes reach various levels in the hopper opposite the cell wheels 17 the pins 21 are projected during their travel through the lower revolution of the drum 20' and are retracted during their travel through the upper revolution of the drum. Thus, the fingers 21 continually move the cigarettes upwardl;l across the hopper so that the hopper level will remain constant and of uniform distribution to permit cigarettesV to be discharged through the discharge opening 9' with out bridging or the like so that they may bc fed to a cigarette wrapping machine or lter mouthpiece applying machine.
