Abstract

A packaging machine utilizes a rotary drum having a circumferential row of pockets formed in the peripheral surface thereof for picking up articles from a pick-up zone, and discharging the articles in a discharge zone. The drum contains a plurality of pistons reciprocably confined therein; a single piston is associated with each pocket and includes a plunger which reciprocates into and out of its associated pocket during rotation of the drum about a horizontal axis. A vacuum is applied to each pocket and to the interior surfaces of its associated piston as the pocket traverses the pick-up zone to pick up an article in the pocket and at the same time, hold the plunger inwardly out of the pocket; this vacuum is terminated as the pocket traverses the discharge zone, thus allowing the article therein to be discharged, and the plunger to descend by gravity into the pocket to assist in the discharge if necessary.

ARTICLE PACKAGING MACHINE BACKGROUND OF THE INVENTION This invention relates in general to an ariicle packaging machine for picking up a plurality of articles from a source, and depositing each of the articles at a precise location.

One example of where such a machine can be utilized is in filling a receptacle such as a web the latter commonly being a sheet of plastic material having a plurality of pockets formed therein, each pocket being sized to receive one or more of such articles. The receptacles which are to receive the articles need not necessarily be in the form of such a web however; they might also be bottles or other type containers capable of receiving one or more of such articles. After each receptacle is filled, it it generally closed at a subsequent station to complete the packaging operation.

The problems encountered at present with such machinery revolve around the speed of operation, reliability, and/or the complexity thereof. As the speed of operation is increased, the reliability of the machinery decreases; because of the increased speed of operation of the machinery, there is increased likelihood of the machinery not discharging the articles at the proper time or place, or of not discharging the articles at all. To provide for more accurate and positive discharge of the articles, more complexmachinery has been devised utilizing cams, etc., with the result that the speed of operation may decrease; also, the more complex machinery required a larger number of moving parts, and is necessarily larger, the'increased complexity tending to increase maintenance problems. Typical machinery utilized at the present time for handling articles which are to be picked up, and then deposited or discharged at some particular location are illustrated in U.S. Pat. Nos. 1,457,775; 2,198,976; 3,206,062; 3,387,746; and 3,533,535.

Thus, what is required is a compact machine of relatively simple construction which is capable of rapidly and accurately picking up a plurality of articles from a source, and depositing these artilces into one or more receptacles or containers. Also, since a typical environment in which such a machine might be utilized is that of packaging tablets, pills, or capsules, it is also desirable that such a machine be readily usable in conjunction with standard commercial tablet counting machinery. While the present invention is not so limited, this is the environment which will be used as an example in discussing the operation of each of the embodiments of the present invention.

SUMMARY OF THE INVENTION The present invention relates to an article packaging machine which utilizes a rotary drum which rotates about a horizontal axis. The drum has a pluraluty of pockets formed in the outer peripheral surface thereof, the pockets being arranged in one or more circumferential rows.

The drum has a transverse bore formed about the axis of rotation, and a plurality of cylinder bores formed therein, each cylinder bore extending between a single associated drum pocket and the transverse bore. The drum also includes two passageways extending between each drum pocket and the transverse bore, one of the passageways communicating with the leading bottom portion of its associated drum pocket, and the other passageway communicating with the trailing bottom portion of the drum pocket.

Reciprocably confined within each cylinder bore is a piston having a plunger, the latter reciprocating into and out of its associated drum pocket as the drum rotates about its axis of rotation.

A circular plug of substantially the same diameter as the transverse bore is stationarily mounted therein, the former having a vacuum passageway formed therein which includes an arcuate portion or part which extends radially inwardly from the outer peripheral surface of the plug. The arcuate portion overlies the cylinder bores andd passageways leading to a circumferential row of drum pockets, so that as the drum rotates around the plug, each pocket and the interior surfaces of its associated piston has a vacuum periodically applied thereto; the plug acts as a valve.

While each drum pocket traverses the outlet of a supply manifold containing a plurality of articles, the vacuum is applied to the pocket and its associated piston as stated above, and a predetermined number of articles are drawn into the drum pocket, the pocket being sized to accept only this number of articles. Because vacuum is also applied to the interior surfaces of the piston associated with each drum pocket, the plunger of the piston is held radially inwardly out of the drum pocket. As the drum pocket with its contents rotates to a lower position whereit is desired to discharge the article(s), the vacuum to the pocket and its associated piston is terminated, thus, allowing the article(s) to be discharged, and the plunger to descend by gravity into the drum pocket to assist in the discharge if necessary. The drum then continues to rotate, and as each pocket approaches the pick-up zone once again, its associated piston reciprocates radially inwardly due to gravity before vacuum is once again applied to the piston to hold it in this position.

FIG. 3 is a sectional view taken through line 3-3 of FIG. 2 showing the interior construction of the drum.

FIG. 4 illustrates a second embodiment of the invention in which the entire drum assembly along with the manifold is mounted upon a carriage for horizontal movement.

FIG. 5 is a sectional view taken through line 5-5 of I DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, a side elevational view of the article packaging machine of the present invention is shown being utilized in conjunction with a standard commercially available tablet counting apparatus such as that manufactured by the Merrill Division of Pennwalt Corporation in Chicago, Ill.

The article packaging machine includes a manifold 12 containing a supply of articles, and a drum 14 for picking up articles from the manifold and discharging them at a lower discharge zone. Manifold 12 receives the articles (tablets or capsules in the instant illustration) from tablet counting apparatus 16, the latter periodically starting and stopping depending upon the level or quantity of articles contained within manifold 12.

Articles are released from an auxiliary hopper (not shown) into primary hopper 18 of apparatus 16. A plurality of slats move beneath hopper 18 to pick up articles therefrom, and move them upward beneath an anti-shingling brush 20 which serves to assure that the articles in each of the slats are not stacked on top of each other. The slats move the articles from hopper 18 beneath brush 20, and deliver them into manifold 12, the latter comprising a plurality of tubes 22 (see FIG. 2 also) which deliver the tablets to a rotary drum 14. Machine 10 utilizes vacuum to pick up articles from manifold 12, and hold them on the outer periphery of the drum discharging the articles into a web 24 moving beneath the drum.

Drum 14 rotates about horizontal axis 15 while picking up and depositing the articles during the operation of the machine. In this embodiment of the invention, axis 15 of the drum remains stationary during the operation of the machine while web 24 is pulled in a horizontal direction as indicated by the arrow 25; that is, axis 15 does not move forward and rearward in a horizontal plane during operation of the machine as it does in a second embodiment to be discussed below. As web 24 is pulled forward in the direction of arrow 25, the rotation of drum 14 is synchronized therewith so that the drum rotates in a counterclockwise direction as indicated by arrow 26 to pick up articles from manifold 12 and deposit them into each of the pockets 28 formed in the web.

The web moving mechanism 32 moves forward from a first stationary position to a second stationary position in the direction of arrow 25, the clamps holding the web during this forward stroke or movement are released, and mechanism 32 is returned in the rearward direction of arrow 30 to the first stationary position. The clamps of mechanism 32 then once again clamp or grasp web 24 for the next forward stroke. It is noted that drum 14 does not rotate when web moving mechanism 32 is returning in the direction of arrow 30 to its first stationary position. Consequently, no articles are picked up or discharged by the drum on the rearward stroke of mechanism 32. Drum 14 picks up articles from manifold 12 only when rotating in the counterclockwise direction indicated by arrow 26, i.e., when web 24 is moving in the forward direction indicated by arrow 25.

The means for moving web 24 forward, includes mechanism 32 which includes lower clamps 34, and upper clamps 36, the latter being operated by solenoid 38. Web 24 is between clamps 34 and 36, and moved forward a distance determined by the stroke length of mechanism 32, after which the upper clamps 36 are released so that mechanism 32 can be returned to its ini' tial position where the cycle is repeated; once again, clamps 34 and 36 grasp or clamp web 24, and move the latter in a forward direction. As web moving mechanism 32 moves forward in the direction of arrow 25, rod 40 fixedly connected to mechanism 32 is moved forward; consequently, rack 42, which is secured to rod 40 by means of bolts 41, is also moved forward. As rack 42 moves in a forward direction, it rotates gear 44 in a counterclockwise direction as indicated by arrow 26 in FIG. 1. As gear 44 moves in a counterclockwise direction pawl 46, which is pivotedly connected to the gear, engages the teeth of ratchet 49, the latter being rigidly connected to drum 14 by being threadly connected at 50 to plate 52, the latter being secured to the drum by bolts 54. Thus, drum 14 is moved in a counterclockwise direction. A spring 56 maintains contact between the pawl 46 and ratchet 48 during rotation of the drum. Rotation of drum 14 is terminated upon mechanism 32 reaching the end of its forward stroke. When reaching this latter position, solenoid 38 releases upper clamps 36, and mechanism 32 is returned to the rearward or initial position.

During rearward movement of mechanism 32, rack 42 rotates gear 44 in a clockwise direction. Since the gear 44 is now moving in a clockwise direction, pawl 46 is doing likewise and thus riding over the teeth of ratchet 48 in a non-engaging manner, thus preventing rotation of drum 14 during this rearward movement of mechanism 32. Thus, in this embodiment, when web 24 not moving, drum 14 is not rotating. Referring to FIG. 2, it is noted that a support member 56 having a plurality of grooves 58 formed therein, is located beneath web 24 and supports the latter during its forward movement. Pockets 28 of the web slide in grooves 58 of the support member as the web is moved forward. Although not shown, there is a second group of clamps similar to clamps 34 and 36, which grasp web 24 during the rearward movement of mechanism 32 to prevent web 24 from accidentially being moved rearwardly also. This second group of clamps is released when mechanism 32 reaches its most rearward or first stationary position at the end of its rearward stroke.

Drum 14 has a transverse bore 60 formed about axis 15, and extending inwardly from one end of the drum. Extending into transverse bore 60 is a stationarily mounted circular plug 62 having a vacuum passageway 64 formed therein, the latter passageway terminating with an arcuate portion 66.

Referring to FIG. 3, it can be seen that a circumferential row of pockets 68 is formed in the outer peripheral surface of drum l4, and that a cylinder bore 70 extends radially inwardly from each of the drum pockets, each cylinder bore communicating with transverse bore 60. As drum 14 rotates in a counterclockwise direction, the leading edge 70a of each cylinder bore rotates past edge 66a of arcuate portion 66 of the vacuum passageway formed within plug 62, thus opening communication between the vacuum passageway and the associated drum pocket via passageways 72 and 74.

Reciprocably confined within each cylinder bore 70 is a piston 76 having a plunger 78 which reciprocates into and out of its associated drum pocket during rotation of drum 14. Each piston includes an annular stop 84 which abuts against an annular shoulder 86 to limit the inward movement of the piston, and against an annular piston retainer 87, which is removably mounted within the cylinder bore, to limit the outward movement of the piston.

As the leading edge. 68a of each drum pocket begins to rotate past opening 82., an article 80 will begin to descend into the drum pocket due to gravity and the vac uum which is being applied to the drum pocket via passageway 72. The leading portion 90 of each article is pulled into the leading bottom portion of the drum pocket as a result of the vacuum being applied to the latter through the latter mentioned passageway. As the drum continues to rotate, drum pocket 68 continues to traverse the pickup zone defined by the manifold and drum until the trailing edge 68b of the drum pocket reaches position 88. At this position the entire article 80 is resting within the drum pocket the trailing portion 92 of the article being pulled into the trailing bottom portion of the drum pocket by the vacuum being applied through passageway 74. By arranging passageways 72 and 74 as shown, each article 80 is properly directed into each drum pocket 68.

It should also be noted that vacuum is also applied to the interior surfaces of piston 76. This acts to hold piston 76 inwardly as each pocket rotates from the pickup zone to the discharge zone. When a drum pocket 68 with article 80 therein reaches the discharge zone where it is desired that the article be discharged, the vacuum to the drum pocket is terminated. This is accomplished when trailing edge 70b of the associated cylinder bore is substantially in line with edge 66b of arcuate portion 66 so that article 80 may be discharged via the force of gravity into pocket 28 of web 24. At this point, piston 76 also descends via the force of gravity to provide assistance in discharging the article if it is necessary.

, As drurn 14 continues to rotate, piston 76 will reciprocate inwardly once more prior to reaching the piston where the vacuum is applied once again.

. Referring to FIGS. 4 and 5, a second embodiment of the invention is illustrated wherein the web moving mechanism moves the web forward to a predetermined forward position while the drum and manifold are also moved to a forward position; the sequence is timed so that the drum and manifold arrive at the forward position either substantially at the same time, or slightly behind the time the web reaches its forward position.

Referring to FIG. 4, it can be seen that a motor 98 is utilized for driving a sprocket 100, motor 98 being fixedly mounted to frame 11 of the machine. As sprocket 100 rotates in counterclockwise direction, chain 101 is driven in the same direction, thus rotating a larger sprocket 102 in a counterclockwise direction. The rotation of the latter causes crank 104 which is fixedly connected to a shaft 105 on which sprocket 102 is mounted, to rotate in a counterclockwise direction; this causes follower 106 to ride in slot 108 of crank 110, causing the latter to rotate in a counterclockwise direction about axis 111 which causes crank 112 to move in a forward direction by means of being connected at 113 to crank 110. Carriage 114., thus moves forward in a horizontal direction because crank 112 is pivotly connected to the carriage 114 at point 1 15. The carriage is guided by supporting guide rods 117 to its extreme forward position as determined by the stroke of the crank arrangement 104-110-112.

Since the manifold 12' and 14' are mounted on carriage 114, each is moved in a forward direction, gear 44' rotating in a clockwise direction as it moves over rack 42', the latter being stationarily mounted to frame 11' of the machine. As gear 44 rotates in a clockwise direction, pawl 46 rides over the teeth of ratchet 48 thus allowing drum 14 to move forward without rotating. After drum 14 reaches it extreme forward position as determined by the crank mechanism, the drum will be returned to its rearward position, thus rotating gear 44' over rack 42 and causing the former to rotate in a counterclockwise direction. This causes pawl 46 which is pivotly connected to gear 44' to also rotate in a counterclockwise direction and drivingly engage the teeth of ratchet 48, thus rotating drum as carriage 114 returns to its rearward position and discharging articles into pockets 28' of web 24. The construction of drum 14 and the means for rotating the same are identical to that shown in FIGS. 13. Thus, it can be seen that forward movement of carriage 114 moves the drum and manifold forward without rotating the drum; the discharge portion of the cycle is on the return or rearward stroke of carriage 114 which acts to rotate drum 14 in a counterclockwise direction to pickup and deposit articles into web 24'. At the completion of the rearward stroke of carriage 114, the web moving mechanism is once again moved forward simultaneously with the forward stroke of carriage 114, the latter reaching the end of its forward stroke substantially at the same time, or slightly behind the time that web moving mechanism 32' reaches its extreme forward position. The web moving mechanism 32 is similar to that shown in FIGS. 1 3, and its operation is synchronized wth the operation of drum 14'.

The operation of the machine is shown more clearly in FIGS. 6, 7 and 8. FIG. 6 illustrates carriage 114 at position A prior to beginning its forward stroke; during the forward stroke, gear 44" is rotated over rack 42, thus causing the former to rotate about horizontal axis in a clockwise direction and causing pawl 46' to ride over the teeth of ratchet 48, thus preventing rotation of drum 15 during the forward stroke or movement of carriage 114. As previously noted, web moving mechanism 32 will reach the end B of its forward stroke substantially at the same time as or prior to the time carriage 114 reaches the end B of its forward stroke.

Once carriage 114 has reached the end B of its forward stroke rearward or return movement of the carriage causes gear 44 to rotate in a counterclockwise direction, thus picking up articles from manifold 12, and depositing them into pockets 2% of web 24' as illustrated by the arrows 120. This operation or sequence operates in the same respect as that illustrated in FIG. 3; that is the pockets of drum 14 rotate past the pick up zone to receive articles $0 from the outlet of the manifold; drum 14' then continues to rotate in a counterclockwise direction until reaching the discharge zone where the vacuum to each of the drum pockets is terminated to release the article into a web pocket while receiving additional assistance if necessary from piston 76 to positively discharge the article into its associated web pocket. The entire operation must be timed so that web 24' is stationary while the carriage 114 is moving in a rearward direction to discharge the articles. However, at the completion of rearward stroke of carriage 1 14 the web advancing mechanism is again returned to its extreme rearward position A to grasp the web and move it forward to its extreme forward position B.

In both embodiments described herein, the operation of the drum is synchronized with that of the web moving mechanism, and the spacing between ajacent drum pockets in a circumferential row must be coordinated with the spacing between adjacent web pockets in a row.
