Filed July 8, 1963, Ser. No. 293,463 Claims. (Cl. 235-98) The present invention relates to machines for counting small articles such as screws, bolts, nails and other small articles of a similar nature.
The present invention is a continuation-in-part of an application filed by us in the United States Patent Ofiice on July 3, 1962, Ser. No. 207,305 for Article Counting Device.
Considerable time is consumed in the tedious hand operation of group counting such small articles, particularly screws and bolts, especially when prepackaging small individual 'group amounts.
The prior art reveals a number of counting machines adapted to count at predetermined number of pills or tablets and deposit them in separate containers, some of which are progressively conveyed past the counting device. Some of these counting devices are designed for use by the manufacturer of pills or tablets, rather than by the individual pharmacist, wherein each successive prescription filled has a number of pills or tablets which is different from the previously filled prescription. These machines, as shown by the prior art, so far as we have been able to determine, do not provide a device capable of being actuated for counting a selected number of articles for individual orders. It is highly important in the handling of pharmaceutical tablets, which are to be internally consumed, that the tablets be undamaged and bekept clean to present a perfect appearance to the consumer. Article counting machines, as shown by the prior art, so far as we have been able to determine, do not provide a device capable of rapid counting, a minimum of ten thousand or more per hour in groups of a predeter mined number, screws, nails or bolts and depositing the groups in separate containers. A common method of packaging a selected number of screws or the like is to count the first group, weigh this group and thereafter ap' proximate the group count by scale weights. This frequently results in the inclusion of one or two more screws than is necessary to complete the desired count. It is, therefore, important, from an economic standpoint, to provide a low cost prepackaging method of accurately counting screws, bolts and articles of similar nature.
It is, therefore, the principal object of the instant invention to provide a device which will actually count or separate a selected number of such small articles from a hopper containing a reserve supply- Another object is to provide a device which will count a selected number of articles without any damage thereto.
Another object is to providea counting machine which is controlled by a preset electrical means for counting out the predetermined number of articles.
A further object is to provide a device which is fully automatic in the counting operation and does not require manual supervision when the machine has been placed in operation.
Another object is to provide a device which will rapidly count a selected number of screws, bolts and articles of similar nature.
Another object is to provide a device or machine adaptable for handling small articles of various shapes and sizes.
Still another object is to provide a machine of this class which is relatively simple in construction, positive in operation, and which can easily withstand continuous usage with a minimum of service or repair.
3,170,627 Patented Feb. 23, 1965 A further object is to provide a device of this class which may be readily used by manufacturers, or the like, in counting out large volumes of small articles.
Yet another object is to provide a device of this class which may comprise a single article handling unit, or a multiplicity of such units, all controlled by a single electrical counter.
The present invention accomplishes these and other objects by providing a frame having an inclined upper sup port. Motor driven disk means, mounted on the inclined support, is provided with article receiving openings. Electrical counting means operates the motor driven disk means and stops the latter at a predetermined setting when the counting means has been actuated by the passage of the selected number of articles being counted.
Other objects will be apparent from the following description when taken in conjunction with the accompany ing two sheets of drawings, wherein:
FIGURE 1 is a perspective view of the device;
FIGURES 2 and 3 are vertical cross-sectional views taken substantially along the respective line 22 and 3-3 of FIG. 1; and,
FIGURE 4 is a wiring diagram of the counting control means.
Like characters of reference designate like parts in those figures of the drawings in which they occur.
In the drawings:
Referring more particularly to FIGS. 1 to 3, the reference numeral 11 indicates the device, as a whole, which is rectangular in general configuration. The device 11 includes a frame 12 having upper inclined supports 14 and 14A. A motor 24 is mounted within one end portion of theframe 12 and is supported by the support 14. The motor 24 has a drive shaft 26 which projects upward through the support 14. A disk 28 is axially connected to the upwardly disposed end of the drive shaft 26 in flat face to face contact with the surface 30 of the upwardly inclined support 14. The peripheral edge por tion of the disk 28 is provided with a plurality of equally spaced-apart radial notches, slots or recesses 32. A second motor 24A is similarly mounted within the other end portion of the frame 12 and is supported by the support 14A. This second motor 24A has a drive shaft 26A which projects upwardly through the support 14A. Another disk or plate 28A, diametrically substantially equal with respect to the disk 28, is similarly axially connected to the drive shaft 26A so that an arc or periphery portion ofthe plate 28A lies in closely spaced relation with respect to a similar are or peripheral edge portion of the disk 28. The disk 28 and plate 28A both revolve in a clockwise direction as shown by the respective arrows 34 and 34A.
A hopper or bin 36, containing a reserve supply of articles to be counted, such as screws or nails 38, is positioned in spaced relation above and outwardly of the frame 12; An inclined V-shaped trough 40, connected at one end with an outlet of the hopper 36, conveys the screws 38 for discharge on the upper surface 30 of the support 14 at a point adjacent the juncture of the meeting point of the disk 28 and plate 28A. The depending end of the trough 40 overlies a peripheral edge portion of the disk 28 and plate 28A adjacent their juncture. The trough 40 is V-shaped in cross section and the walls forming the V-shape are spaced-apart at theirlowermost edges to define an opening or space 42 therebetween through which the stem portion of the respective screw 38.depends sothat the head portion of each screw is supported by the opposing walls of the trough as the screws travel by gravity toward the lower end thereof. An arcuate slot 41 (FIG. 3) is preferably formed through the support .14 in underlying relation with respect to a peripheral portion of the disk 28 so that the depending free end portion of the screws or nails, being counted, may project downwardly thereinto or therethrough. As the disk 28 rotates, one of the recesses 32 engages the stern portion of one of the screws 38 and carries the latter toward a discharge point adjacent the depending forward edge of the inclined surface 30 where an aperture 43, formed in the inclined support 14 in communication with the slot 41, permits the screw 38 to fall by gravity into a funnel-like chute 43A. During its travel with the disk 28, the screw 38 is maintained in position within the recess 32 by a guide member 45 having an arcuate edge 45A adjacent a peripheral portion of the disk 28. The head of the respective screw, carried by the disk 28, projects upwardly of the upper surface of the disk 28 so that the head portion of the screw passes under the arm 48A of a microswitch 48, mounted on the guide 45, to actuate a counting and control means 54 as is more fully described hereinbelow.
Since the screws are fed by gravity to the pick-up point of the disk 28, they tend to pile up or become bunched at the discharge end of the trough 40. To prevent such irregularity of the sequence of their engagement by the recesses 32 the rotating disk 28A frictionally contacts the stem portion of the screws tending to impart a counterclockwise rotation of the screws which prevents such piling up or congestion at the point of pick-up for counting. As a safety feature in preventing malfunction of the counting operation, the righthand portion as viewed in FIG. 1, of the inclined support 14 upon which the disk 28A is mounted and indicated by the numeral 14A, is separately mounted on the frame 12 for sliding movement toward and away from that end of the frame opposite the disk 28. The section 14A is spring urged toward the disk 28. If, for example, two screws 38 are picked up or become positioned within one of the recesses 32, the combined thickness of the screws forces the disk 28A and panel portion 14A to be moved laterally of the frame 12 away from the disk 28. This movement of the panel 14A positions its righthand free edge portion, as viewed in FIG. 1, against the switch arm 59A of a microswitch 59, mounted on the frame 12, which interrupts the circuit to the counter means 54 and stops operation of the device 11 until the malfunction has been corrected.
A horizontal turret plate of table 46 is supported by the forward side of the frame 12 and is provided with a plurality of circumferentially spaced tubes 46A depending from cooperating openings formed in the table 46. A sack or receptacle 47 surrounds the depending end portion of each tube 46A and receives individual group counts of the screws. As seen in FIGS. 1 and 2, the tubes 46A are positioned in turn below the funnel-like tube 43A, by rotating the table 46, so that the articles 38 fall by gravity through the respective tube 46A and into the sack 47 as the device counts out a series of grouped quantities of the articles as is more fully described hereinbelow.
Referring more particularly to FIG. 4, the counting control or selector mechanism and its wiring is indicated generally by the numeral 54 which operates the counting mechanism 11. The counting control 54 may be housed within the frame or within a separate unit, as shown, and connected with the device 11 by wiring. The counter 54 includes a pair of selector switches S1 and S2 which are manually set by moving the respective indicator 96 and 182 thereof to a preselected number representing the number of articles to be counted as more fully explained hereinbelow.
An alternating current A.C., connected with a source of electrical energy, not shown, applies current to the counter 54 over conductors 56 and 58 through an offon control switch 57. The coil of a first relay R3 is interposed in a wire 58A, connected at one end with the wire 58, which is connected at its other end to the Wire 56 through a set of contacts 63 controlled by a second relay R4. The de-energizing safety switch 59, is interposed in a wire 66 connected with the wire 58A and con- 4- nected, at its other end, with a current source wire 61 through a set of contacts 62 controlled by relay R3 to interrupt the counting action when desired.
A single pole ratchet counting relay R1, having multiple contacts or points, each having a value of one, numbered O to 10, has each of these contacts interconnected with corresponding contacts of the indicator dial of the switch S1. A second single pole ratchet counting relay R2, having contacts or points, each having a value of ten and numbered 0 through 10, is similarly interconnected with the indicator dial of the switch S2. A wire 67, connected with the wire 56, is connected with one end of an inductor coil C1 of relay R1 and the other end of the coil C1 is connected by a wire 67A to the wires 58 and 61. At least one microswitch 48 is interposed in the wire 67.
The inductor coil C2 of relay R1 is connected at one end to the wire 58 and at its other end to the indicator point or contact 10 of relay R1 and with one end of the winding of the coil C3 of a fifth relay R5 by a wire 64. The other end of the coil C3 is connected to the wire 61 by a wire 64A through a set of contacts 65 associated with a sixth relay R6. The coil C4 of relay R6 is connected to the wire 61 and to the 0 contact of relay R1 by wires 66A and 66B. The contact 10 of relay R1 is connected with the point 10 of the dial of selector switch S1 by wires 68 and 70 through a set of contacts 72 associated with the relay R6. A wire 74, connected to wire 64, connects one end of the coil C2 of relay R1 with the coil C5 of relay R2 through a set of contacts 76 associated with relay R3 over a wire 78. The other end of coil C5 is connected to the wire 61. The other coil C6 of relay R2 is connected at one end to the wire 58 and at its other end to the wire 56 through a set of contacts 80, controlled by the relay R3, by wires 82 and 82A.
The motors 24 and 24A are connected to the wires 56 and 61 through another set of contacts 84, controlled by relay R3, by wires 86, 87 and 87A.
A push button switch 88 is interposed in the wire 58A before its connection with the relay R3 for energizing the relay R3, starting the motors 24 and 24A and starting the counting operation.
The indicator 96 of the switch S1 is interconnected with the indicator 98 of relay R2 by a wire 100 and the indicator 102 of switch S2 is connected to the coil C7 of relay R4 through a set of contacts 104 associated with the relay R5 by wires 106 and 108. Wire 110, connecting the contact 5 of the relay R1 with the indicator con-tact 5 of the switch S1, illustrates the manner in which the respective contacts are interconnected. Wires 111, 112 and 113 similarly illustrate the manner of interconnecting contacts of relay R2 with the respective indicator contacts of the switch S2.
Operation selector switch S2 is positioned at 1. The starting switch 88 is closed, which energizes relay R3 and operates its associated contacts. Opening contacts 76 and of relay R3 interrupts the circuit and de-energizes the coil C2 of relay R1 and the coil C6 of relay R2. While the indicator of relay R1 is at point 0 a circuit is' completed from the wire 56 through the coil C4 of relay R6 to the wire 61 over wires 66, 66B and 66A which opens relay R6 contacts 65 and 72 and de-energizes the contact 10 of of relay R1. As the articles being counted, carried by the disk 28, successively close the microswitch 48, coil.
C1 of relay R1 is energized over wires 67 and 67A which progressively moves the indicator 95 of relay R1 from to point 10. When the indicator 95 reaches point 10, a circuit is completed through the coil C2 of relay R1 to release the indicator 95 and reset the latter to 0 position. Simultaneously a circuit is completed to energize the coil C of relay R2 over wires 64, 74 and 78, through the contacts 76 of relay R3 which moves the indicator 98 of relay R2 to point 1 for the count of 10. During its return sweep to 0 position, the indicator 95 of relay R1 is prevented from causing an unwanted count or tripout by contact with the interconnected points, such as point 5, by the circuit over wires 64 and 64A through contacts 65 of relay R6 wherein the coil C3 of relay R5 is energized and opens the points 104 associated with relay R5 which prevents energizing the coil C7 of relay R4. When the indicator 95 of relay R1 returns to 0 position on the coil C4 of relay R6 is again energized to open contacts 65 and 72 which de-energizes relay R5. Subsequent articles 38 closing the switch 48 progressively moves the indicator 95 to the point 5 of relay R1 to complete the count 01515. When the indicator 95 reaches the point 5, a circuit is completed tothe indicator 96 of switch S1 over wire 110 and to the indicator 98 of relay R2 over wire 100 and to the indicator 102 of selector switch S2 which is in turn connected to coil C7 of relay R4 over wire 106 through the points 104 of relay R5 and wire 108 which energizes the coil C7 thus opening the points 63 de-energizing relay R3 and returning its associated contacts to de-energizing position to complete the cycle. In this position the coils, C2 of relay R1 and C6 of relay R2, bias the respective indicator 95 and 98 to 0 position.
