CAPPER WITH ORIENTING ATTACHMENT BACKGROUND OF INVENTION Apparatus for applying closures to containers of the kind with which this invention is concerned are disclosed in U.S. Pat. Nos. 2,744,363, 2,082,048 and 3,054,240. In each of these patents a rotor moves containers standing upright along a circular path and there are transfer arms mounted on the rotor which are moveable thereby to take closures from a stationary support adjacent to rotor and move them to. positions above the rotor for application to containers on the rotor. The apparatus shown in U.S. Pat. No. 3,054,240 is designed to orient the closures after they are transferred to the rotor to apply them to the containers in a determined position of orientation. The apparatus of this invention is designed to effect orientation of the closures prior to positioning above a container on the rotor thereby to speed up the operation and to simplify the construction and operation of the closure applying means.

SUMMARY OF INVENTION Apparatus for applying closures to containers wherein the containers are supported standing upright in a predetermined position of orientation for movement along a predetermined path and closures are delivered one at a time to a position close to the path in a predetermined position of orientation relative to the containers, comprising a transfer arm supported for angular movement about a vertical axis from said path to said position and back to said path to take a closure from the support and position it above the path of movement of the containers for application to a container and means for rotating the closure about a vertical axis as the transfer arm moves it from said support to said path to compensate for angular displacement of the closure relative to said path produced by said angular movement of said transfer arm. The containers are moved along a circular path by a rotor which rotates about a vertical axis to which they are delivered standing upright, and the transfer arms are mounted on the rotor for rotation about vertical axes. The closures are delivered to a position close to the rotor by an inclined chute and there is means for rotating the rotor relative to the chute to move the transfer arms successively by the chute and means for rotating the transfer arms as they travel by the chute about vertical axes to pick a closure from the chute and move it to a position on the rotor. Each transfer arm has at its distal end an adaptor rotatable about a vertical axis designed to pick a closure from the chute and there are interengageable means on the adaptor and stationary parts of the machine for effecting rotation of the adaptor as the transfer arm swings outwardly and back to position the adaptor for taking the closure from the chute and for re-orienting the closure as it is moved to said position above the rotor by the amount of the angular displacement caused by angular movement ofthe transfer arm.

Capping apparatus of the kind with which this invention is concerned is shown and described in the U.S. patents to Everett Nos. 2,082,048, 2,744,368 and 3,054,240 and so for the purpose of describing the novel features of this invention only such of the construction of the aforesaid apparatus will be described I herein as is essential to a clear understanding of the nature of this invention. Referring to FIG. 1 the containers 10 which are to be capped are delivered to the apparatus by suitable conveyor mechanism including a conveyor 12 along one side of which there is a guide rail 13 and along the other side of which is a spirally grooved rotatable cylinder 14 adapted to engage and arrange the containers in spaced relation on the conveyor and to advance the containers in timed relation to successive openings in a transfer disc 16. The transfer disc 16 is arranged to feed the containers onto a rotary table 18, FIG. 2, where they are engaged by clamping means 19, 21 such as employed in U.S. Pat. No. 2,082,048 which support them in upright positions in alignment with closure applying means indicated generally at 22.

There are a plurality of closure applying means 22 mounted to revolve about a circular stationary shaft 44, each closure applying means including a housing 60 provided at its lower end with a gripping element 46 mounted for vertical reciprocation in a cylindrical casing 37. The lower end of each casing 37 is secured to a supporting ring 62 which is in turn secured to an elongated inner sleeve 64 supported for rotation about the central shaft 44. The inner sleeve 64 is keyed to an outer sleeve 66 secured at its lower end to a gear 68 which meshes with a drive gear 70 fastened to a vertical shaft 88. The shaft 88 is rotated through a worm gear drive, 74, the worm being fast on a shaft '71 driven by a motor M through a gear reduction unit GR and a drive belt B. The upper end of each casing 37 is attached to an upper supporting bracket 78 also mounted to rotate about the central supporting shaft 44. Provision is made for reciprocating the gripper housing 60 vertically to cause the gripper element 46 to first pick up a closure from a transfer arm 30 and then to apply the closure to the container during the revolving movement of the housing and to this end, each housing is provided with a cam roll 80 arranged to cooperate with a cam track 82 formed in a stationary cam 84 fast on the stationary shaft 44. As previously related, a transfer disc 16 delivers the containers supplied by the. conveyor 12 to the table and is mounted on a vertical shaft 86 arranged to be rotated from a shaft 88 by way of a chain and sprocket drive 90. A discharge disc 92 is mounted on the upper end of a vertical shaft 94 arranged to be similarly rotated through a chain. and sprocket drive 96. The drive for the spiral groove cylinder 14 is provided for by a chain and sprocket drive 98 from the shaft 88, bevel gears 100 and a horizontal shaft 102 connected by spur gears 104 to a shaft 106. The shaft 102 is connected by a chain and sprocket drive 108 to the shaft 101 upon which the grooved cylinder I4 is mounted.

The closures are supplied by an inclined chute 24 from a hopper as shown in U.S. Pat. No. 2,082,048, wherein provision is made for feeding the closures 26 right side up to the inclined chute .24. The lower or discharge end of the chute is located close to the table at a level above the tops of the containers as shown in I FIG. 2.

The closures are transferred from the lower end of the chute 24 to a position for application to the containers by transfer means 28 which move the closures to a position to be engaged by the closure applying means 22 while the latter are revolving. As herein shown each closure applying means 22 is provided with a transfer means 28 comprising an oscillatory transfer arm 30, mounted to the lower end of a vertical rocker shaft 32 supported in lower and

upper brackets

34 and 36 respectively, secured to the supporting casing 37 of the closure applying. means 22. The upper end of each rocker shaft 32 is provided with an arm 38 having a roller 40 arranged to cooperate with a stationary cam 42 fast on the central shaft 44 for rocking of the transfer arm from a position in alignment with the lower end of closure supply chute 24 to withdraw a closure there from as indicated at A in FIG. l to a position in vertical alignment with the closure gripping element 46 of the associated closure applying means 22 as indicated at B in FIG. 1 during the continuous rotation of the apparatus. Springs 48 secured at one end to a collar 50 rotatably mounted on the central stationary shaft 44 are connected to the respective arms 38 to hold the. rollers 40 against the cam 42. As herein shown each transfer arm 30 is provided at its outer end with a picker 52 which is caused to pass under and engage the end most closure extending from the lower end of the inclined supply chute 24 to withdraw the closure from the chute. The form of the picker 52 will depend upon the kind of closure to be applied.

In the normal operation of the machine the containers are delivered by the table 13 into operative relation to successive closure applying means 22, at station B where the closures are applied and are discharged from the machine at station F by the disc 92. Each closure transfer arm 30 is actuated by the cam 42 to take a closure from the supply chute at station 'A as shown in FIG. 1 and to present the closure to the gripping element 46 at station B whereupon the housing 60 is elevated to cause the gripping element to pick up the closure whereupon the transfer arm 30 is moved out wardly by the cam 42 to position it for picking a succeeding closure from the chute at station A. As also in- C and the gripping element 46 is moved downwardly at i this station to apply the closure to its container. 'It is to a be observed that in operation the closure is appliedto I the container. during the movement of the container along that portion of the path of rotationof the con-,

tainer generally indicated betweenthe stationslB andfi D. The capped container moves from the station B all} g V I the way around to the station F where it is discharged by the disc 92 on to the conveyorl2.

/or indicia on the container. Sometimes a closure may have ports or spouts which desirably should be oriented V with respect to the exterior or interior configuration of 1 the container. As previously pointed out the closures in whatever form are delivered by the chute 24 in a predetermined position of orientation relative to the path of: movement of the closure applying meanson the table by the chute 24 at the station A. The delivery end of the chute is located at a radial distance from the center of rotation about which the containers and closure applying means travel which is greater than the radial distance of the containers'and closure means frorn'theirl center of rotation and so as each transfer armap-. proaches the lower e'nd of the chute at Station A, it is I moved outwardly about its pivot 32 to interceptand I pick a closure from the lower end of the chute.; Follow- I ing picking the transfer arm continues to move while in this outwardly displaced position all the Way ar'oundto station B where it isswung inwardly to dispose the closure beneath a gripper element 46 for application to the top of a containenThe pivotal movement of the I transfer arm as it is moved from the lower end "ofthe chute backto the locus of the line of center of the tops of the containers and closure applying means displaces I the angular orientation of the closure from that which Q it had at the lower end of the chute and hence in rela': tion to the path of movement of the containers and clofj.

sure applying means so it is necessary to rotate the closures on the transfer arms as the latter are movedtoward the closure applying means to restore them to the.

same position of orientation that they had at the lower end of the chute. Optionally the closures may be totated to a different position of orientation if this. is I I I found to be desirable. It is therefore the purpose of this invention to reorient the closures as they travel from the lower end of the chute to the closure.applying means so that at the place of application theywill have the same orientation as when taken from the chute Orif not the same position of orientation to a predeter-. A 1 mined position of orientation such as wouldbeconsis- 1v tent withtheir application to the containers. I

As herein illustrated thisis achieved as is shown in FIGS. 5,6 and 7 by mounting the picker 52 on the transfer arm 30 for rotation about a perpendicular axis L. V and by providing means for rotating the picker about I its axis on the transfer arm to compensate for theangur, lar displacement produced by the angular movement of I I the transfer arm. Various means may be emplo yed to I effect this rotation and as herein illustrated is provided for by two pins, 112, 114 fixed to the picker so as to project radially therefrom and a pair of

abutments

116, 118 mounted by means of

brackets

120, 122 at the lower part of the chute so that as the transfer arm approaches the lower end of the chute the pin 112 is intercepted by the abutment 116 to rotate the picker in a counterclockwise direction to a position for picking off a closure from the lower end of the chute and as it continues beyond the lower end of the chute after having picked off a closure the pin 114 is intercepted by the abutment 118 so as to rotate it in a reverse that is clockwise direction by the same amount that it was rotated in a counterclockwise direction thereby disposing the closure when the arm moves inwardly to position the closure below the gripping element 46 in the same relative position it had thereto at the lower end of the chute.

FIG. 9 shows a closure 26 of rectangular configuration with a raised arrow 124 on its upper side which is desirably applied to the container with the arrow parallel to the long side of the container whether it is of rectangular or oval configuration. The raised arrow conveniently provides means for guiding the closure down the chute 24 in a predetermined position by engagement with a slot 126 at the top of the chute. Since the underside of the closure is hollow and of rectangular configuration a rectangular button 128 is provided on the picker 52 for engagement with the open lower side of the closure to pick it from the chute. A circular closure is shown in FIG. 11 which also has a raised arrow on the top side which guides it down the chute in a predetermined position of orientation. The circular closure is a plug type element and so is provided with diametrically spaced openings or holes 130*130 at its underside and the picker 52 with correspondingly spaced buttoms or pins 132- 132 for entering the holes to pick the closure from the chute. 1n the absence of some means such as an arrow at the top a rectangular closure may be guided solely by engagement of its sides with the sides of the chute and in the event that the closure is in the form of a circular cap a pair of downwardly extending diametrically disposed lugs fixed to the inside for engagement with a guide at the bottom of the chute may be employed. A closure with a spout may be guided by the spout or a closure with interior projection by a guide projecting upwardly from the bottom of the track. The form of the picker will depend upon the configuration of the closure and the orientation of the picker will depend upon the angular travel of the transfer arm and/or the desired orientation of the closure relative to the container.

As herein illustrated the adapter is rotated to reorient the closure substantially as soon as it leaves the lower end of the chute, however, it is within the scope of the invention to effect the rotation at any place along the path of movement of the picker between stations A and B and it is also within the scope of the invention to rotate the closure through an angle to compensate for the displacement produced by the angular movement of the transfer arm and/or a lesser or greater angle.
