Chambers, 317 E. 13th St., Hialeah, Fla. 33010 Filed May 26, 1965, Ser. No. 458,868 6 Claims. (Cl. 221-120) This invention relates in general to semi-automatic dispensing machines and more particularly to a machine for selectively dispensing predetermined pluralities of a pre determined number of like bodies from a number of selections of different sizes and shape, such as pills, tablets, and capsules used by the medical profession.
Prior to this invention, small bodies such as pills, tablets and capsules were dispensed for use by manual count or by weight, which methods are inaccurate, time consuming and in many instances wasteful of the products.
The present invention overcomes the above objections and disadvantages by the provision of a manually operated selective machine in which a relatively large number of like bodies, such as pills, tablets or capsules of different size and shape, are loaded in separate magazines and by simple manual selective manipulation various quantities of each type may be quickly selected and dispensed by gravity into a container by pro-setting an exact counting means, which features are principal objects of the invention.
Another object of the invention is the provision of a rotary dispensing device for retaining a large plurality of selectively separated different types of bodies including a means for selectively registering and dispensing a predetermined number of each different type.
Another object of the invention is the provision of an electro-meohanical rotary dispensing device including a plurality of vertical magazines for holding quantities of different types of small bodies in separate vertical columns for selective electric controlled gravity dispensing.
Another object of the invention is the provision of a selective dispensing device for retaining predetermined pluralities of different small bodies in separate vertical magazines with electric means for selectively registering each of said magazines at dispensing position including an electroarnechanical dispensing means for the gravity release of a predetermined number of bodies [from each said magazine when registered.
These and other objects and advantages in two embodiments of the invention are shown and described in the following specification and drawings, in which:
FIG. 1 is a side elevation of a preferred form of the dispensing device in reduced scale.
FIG. 2 is a top plan view thereof.
FIG. 3 is an enlarged cross sectional plan view taken through section line 3-4, FIGQI.
FIG. 4 is an enlarged cross sectional plan view taken through section line 44, FIG. 1.
FIG. is an enlarged fragmentary cross sectional view taken through section line 55, FIG. 1.
FIG. 6 is an enlarged cross sectional plan view taken through section line 66, FIG. 1.
FIG. 7 is an enlarged cross sectional plan view taken through section line 77, FIG. '1.
FIGS. 12 and 13 illustrate fragmentary plan and side elevations, respectively, of an alternate form of dispenser in reduced scale.
Referring to FIGS. 1 and 2, the dispenser is mounted on a base 1 on which is journalled a magazine assembly 2 for rotation about a vertical axis a. A selector drum 3 is positioned coaxial with the magazine assembly and is adapted to rotate therewith. A push button assembly 4 is positoned on base 1, adjacent drum 3. A gear motor 5 is secured in base 1 for selectively rotating the magazine assembly 2 when periodically energized, better shown in FIG. 5.
The magazine assembly includes a lower disc 6 and an upper disc 7 which are adapted to rotate together by construction hereinafter described. In this particular embodiment, six tubular vertical magazines 88, 9-9, 10 and 11 have the same outside diameter but bores of different dimensions therethrough.
Each of the magazines is intended to be made from substantially transparent plastic material, such as polystyrene, with conical upper ends 12 to facilitate the loading of bodies by manual or an automatic feed means, not shown. Each magazine is quick detachable and retained on the dispenser by engagement of the lower end in a pocket in disc 6 and by its upper end in a resilient clip 13, thus each magazine may be removed and replaced by simple manual manipulation, better shown in FIG. 3.
Referring to FIGS. 1, 4 and 5, the magazine assembly shown in FIG. 1 is supported by a fixed vertical tube 14, of dielectric material, coaxially secured to a lower tube 15 by screw means 16. The lower end of tube 15 is secured in a bore in base 1 against a shoulder 17,
The upper disc 7 is centrally retained in the inner race 18 of a ball bearing and the outer race 19 of the bearing is fitted to the inside periphery of tube 14- against a stop ring 20, as shown. The lower disc 6, which contains the six equi-distant pockets for the magazines, is journalled for rotation about the outside periphery of tube 14 and each of the six pockets 29 for holding the magazines have a coaxial bore therethrough for the free gravity descent of each body therethrough.
An internal ring gear 22 is secured to the outside periphery of disc 6, as shown, for engagement by a pinion 23, which is driven by gear motor 5, which motor is mounted in a way means 24 in base 1 with a spring 25 normally holding the pinion 23 in mesh with ring gear 22. The drum 3 is integral with the ring gear 22 and extends downward around tube 15 with predetermined clearance therebetween. The ring gear also has bores 26 therein which coincide and are coaxial with bores 21 in disc '6.
Referring to FIG. 6, the upper side of ring gear 22 is provided with six shutters 27 of magnetic material with each having an upturned portion for attraction by an electro-magnet. Each shutter is pivoted for oscillatory movement about a vertical stud 28 and normally retained, as shown in full lines, by spring 29 anchored in gear 22 and normally holding each shutter 27 against a stop pin 30 with the outer end thereof normally intersecting the junction of bores 21 and 26, which position will hold all bodies in each magazine against gravity in the position shown in FIG. 5. It is now apparent that when the gear motor 5 is energized, the magazine assembly 2 will rotate about its principal axis a shown in FIG. 2 and carry the magazines and the bodies therein with the lower end of each body resting upon a corresponding shutter 27. Selectivity is accomplished by rotating the desired magazine to a position over a dispensing zone on base 1 for holding a receptacle 0 for receiving the dispensed bodies, shown in FIGS. 1 and 5.
Referring to FIGS. 5 and 6, an electro-magnet 31 is secured within tube 15 by screw and bracket means 32 With the core 33 thereof extending laterally through a clearance aperture in tube 15, as shown. It is now apparent that each upturned portion of each shutter 27, when selectively registered with core 33, will be attracted thereby when electro-magnet 31 is energized and will move to the position shown in dotted lines against the restraining action of spring 29.
Referring to FIG. 1, each magazine is provided with a plurality of transverse holes 34 therethrough in spaced relation in accordance with the length of a predetermined number of bodies retained in the magazine between the holes. However, certain magazines to be hereinafter described will include a plurality of transverse elongated apertures therethrough instead of holes 34.
Referring to FIG. 4, an electric conducting pin 35 is pointed at its outer end and provided with a knob 36 at its opposite end. This pin may be freely and selectively inserted through any one of the holes 34 in any one of the magazines, the outer end of which will engage a pair of longitudinal spring contacts 37-37, which are secured to the outer surface of the central tube 14, when a particular magazine is registered over the dispensing zone and with the contacts 37. It is apparent that the tube 14 can be made of metal with the elongated contacts 37 insulated therefrom.
Referring to FIG. 5, under the assumption that the pin 35 is inserted in the lowermost hole, shown in FIG. 1, then the six lowermost tablets will descend through bores 21 and 26 by gravity when the shutter 27 is displaced by magnet 31, thus permitting the tablets to descend into a receptacle 0, illustrated resting on the base 1, placed in the dispensing zone.
The push button assembly 4 for the selective rotation of the magazines requires an individual button corresponding with each magazine, the construction of which is illustrated in FIG. 8, wherein a dielectric member 38 is secured to base 1 adjacent the drum 3, as shown in FIG. 1, with siX superposed cylindrical plungers 39, each having a dielectric button 40 on the outer end thereof for bearing identification notation corresponding with each magazine. A conducting sleeve 41 is positioned in each bore connected to a vertical electric conductor 42, common to all six sleeves, by screw means 42s, as shown in FIG. 8. A separate detent means 43 corresponding to each plunger is provided in member 38 for holding the button in each of its two positions, as indicated in dotted lines, and each plunger has a detent means 44 in the outer end thereof for engaging a corresponding electric drum contact 45. The contacts 45 are arranged in equi-spaced helical relation on drum 3 whereby each plunger, when depressed, will engage a contact 45 corresponding with a selected magazine when registered with the dispensing zone. It is to be noted that' the detent 44 will not only electrically engage its corresponding contact but the shape of the latter will serve a detent action to assure accurate registration of a selected magazine with the dispensing zone.
Referring to FIG. 5, a brush 46 is secured to base 1 for contact with drum 3, providing for an electric circuit between the contacts 45 and each plunger 39.
Referring to FIG. 9, a stepdown transformer T provides a safe low voltage for operating the dispenser, the primary of which is connected to a source of electric power L and L through a single pole, single throw switch 47.
A terminal of the secondary of transformer T is connected to one terminal of electro-magnet 31 by conductor 48. The remaining terminal of electro-magnet 31 is connected to one of the pair of terminals 37 by conductor 55. The remaining terminal of the secondary of transformer T is connected to the remaining contact 37 by conductor 53, which circuit is completed by the selected position of the pin 35 in each magazine.
When the rotor is desired to be electrically driven, the typical circuit for the selector elements previously described is also shown in FIG. 9, in which the common conductor 42 connected to all plungers 39 is connected to conductor 48(a) and one terminal of motor and one terminal of latching relay 49, which relay includes a pair of normally closed switch blades 50-51. The blade 50 is connected to the remaining terminal of gear motor 5 by conductor 52 and blade 51 is connected to conductor 53 by a conductor 53a. The remaining termnal of relay 49 is connected to brush 46 by conductor 54 for completing a circuit through all contacts 45.
It is now apparent that when the relay 49 is in its released position, as shown, and a plunger 39 is depressed by its corresponding button and the switch 47 is closed, the drum 43 will rotate the magazine 2 until a contact 45 corresponding'with the selected magazine will engage the depressed plunger 39 which will complete a circuit through the latching relay 39 and open its switch blades 5051, thus de-energizing the gear motor 5 and stopping the rotation of the magazine assembly with the selected magazine in register with the aforesaid zone for discharge into receptacle 0.
To discharge the desired number of bodies from the selected magazine, pin 35 is inserted into a selected hole or slot corresponding to the number of bodies desired, as illustrated in FIG. 5, and the pin will energize electromagnet 31 and operate the corresponding shutter 27, and permit all bodies below the pin to be discharged through bores 21 and 26 into receptacle c. To re-cycle the machine, the switch 47 is then opened and the relay restored to its initial position by releasing the latch therein by well known means, not shown.
It is now apparent that a larger number of magazines may readily be added by merely increasing the size of certain of the elements described.
It is also apparent that in a simplified form of the dispenser the motor means for rotating the rotor may be omitted in favor of selective manual rotation, in which case any well known means of detent between rotor and base may be used in place of the helical electro-mechanical detent shown.
FIGS. 10 and 11 show an alternate form of magazine 56 with longitudinal apertures 57 along its length with a plurality of bridges 58 for reinforcement purposes. This form of magazine is anchored by a cylindrical lower portion in the same pocket in disc 6 as the previously described magazine, and the upper end is anchored to the disc 7 in the same manner as previously described in register with projections 59 integral with the body of the magazine. A slider 60, of tubular spring material with one side thereof open, is frictionally retained on the outer surface of the magazine and has an aperture therethrough forming a pointer 61 for registration with indices lines 72 marked along the length of the magazine, for indicating predetermined number of bodies therein. A hole 62 is provided adjacent the pointer for receiving pin 35, thus providing a more accurate and a wider range of selected quantities of bodies to be discharged than the multi-hole tubes previously described.
FIGS. 12 and 13 illustrate an alternate form of construction for a dispenser having a relatively large number of vertical magazines having a corresponding large number of selections of small bodies. Although the general principles employed are substantially the same as shown and described inthe rotary dispenser, endless belt 63 of the positive tooth driven type are adapted to rotate about a pair of Vertical axes b-C on appropriate sprockets 64, which are driven by a gear motor 65 and pinion 66 through an idler gear 67.
A shutter 68 is pivoted on the lower end of each magazine and normally positioned by spring means, not shown, to hold the bodies within each tube. An electro-magnet means 71 secured to the base and positioned above the dispensing zone is adapted to engage each said shutter means 68 and rotate same to a dispense position when energized. It is also apparent that the drum type of a selecting system previously described may readily be adapted for this type of belt operation by suitable transmission means.
It is also understood that certain other modifications in the construction, utilizing the features above described, are intended to come within the scope of the appended claims. 4
