(Cl. 209-'F2) 15 Claims. 1
This invention relates to mechanism for feeding tubular caps closed at one end and particularly to the means for delivering such caps for collapsible tubes in predetermined positions to a capping station.
The present invention contemplates the provision of agitating and selecting means whereby a sufiicient quantity of tubular caps dropped heterogeneously into a hopper are turned into a required position as with the closed end thereof at the rear, and successively fed at regular intervals without interruption toward other mechanism for performing other operations such as mounting the respective caps on collapsible tubes at relatively high speed.
The invention further contemplates the provision of dependable and rapidly acting means for engaging the successive caps and delivering a cap to a straight chute if the cap is in its required position or delivering it to a reversing or twisted chute if the cap is in a reversed position.
The invention further contemplates the pro.- vision of simple cap agitating means entering the cap hopper and operated by the revoluble cap selecting and forwarding mechanism.
Thevarious objects of the invention will be clear from the description which follows and from the drawings, in which Fig. 1 is a rear elevational view with some parts broken away, of the hopper and the cap selecting and advancing means.
Fig. 2 is a vertical sectional view thereof taken on the line 2-2 of Fig. 1.
Fig. 3 is a top plan view and horizontal sectional view taken on the line 3-3 of Fig. 2, the hopper being omitted, of the chute support.
Fig. 4 is a front elevational view of Fig. 3 partly broken away to show the chutes.
Fig. 5 is a vertical sectional view of the support for the chutes taken on the line 55 of Fig. 4.
Fig. 6 is a bottom plan view partly in section of the cams controlling the point of discharge of the caps.
Fig. 7 is a rear elevational view of the recessed cap-selecting wheel showing two of the selecting arms, the remainder being omitted for clarity.
Fig. 8 is a horizontal sectional view of the selecting wheel, the selecting arm being shown in dash-dot lines in the position assumed thereby when the cap is in the required position in the recess.
Fig. 9 is a perspective view of the cam controlling the discharge of the cap into the reversing chute.
Fig. 10 is a similar view of the cam controlling the discharge of the cap into the straight chute.
In that embodiment of the invention illustrated, the shaft 12 for operating the mechanism is supported (Fig. 2) in suitable bearings arranged in the cross members l3, l4 carried by the upright spaced angle members 15 and I6. Said shaft is intermittently rotated as by means of the chain ii passing around the sprocket Wheel 18 on the shaft, the chain being intermittently driven in any suitable manner. Near its front end, the shaft it carries the selecting wheel l9 provided with a plurality of inwardly extending cap-receiving recesses 20 in its periphery. The front plate 2! suitably secured to the shaft closes oif the front sides of the recesses to retain the caps therein against falling out sideways after the caps have been dropped into the recesses from the hopper 22. v
For pivotally supporting a selecting arm 23 in a radial position across each recess, each of a series of radial plates as 24 (Figs. 7 and 8) is secured at its front edge to the rear face of the Wheel [9 and is fitted into a slot 25 in the inner end portion of the oscillatory arm 23. The inner edges of the plates are fixedly secured together by the ring 26 on the shaft l2, while a suitable pivot pin 21 passes through the inner end of the arm and through the corresponding plate 24, whereby the arm may oscillate on the relatively fixed plate as a guide between the full line and dash-dot line positions-thereof shown in Fig. 8. A spring holding pin 28 through the arm crosses the slot 25 and holds the rear end of the spring 29 inserted into the slot around the pin, said spring passing through a. suitable hole 30 in the wheel and normally pulling the arm toward the wheel, the front ends of the springs for the various arms being secured together in circumferential spaced relation by the wire retaining ring 3!. As best seen in Fig. 8, each of the selecting arms carries near its outer end part, a cap-engaging pin 32 in position to enter the recess 20 at about the center thereof, or if a cap is in the recess to enter the recess or threaded interior of the cap 33 provided the cap is in a reversed position, that it, with its open end in front of the pin. Should the cap be in the required position with the closed end at the rear, the pin engages the closed end as will be explained in more detail hereinafter in connection with the explanation of the control cams 34 and 35 and the by-passing of the straight delivery chute 36 by the reversed caps into the reversing delivery chute 31.
The means for insuring the supply of a cap to a suflicient number of consecutive recesses to insure an adequate supply of caps at the delivery point such as a capping station as the wheel l9 rotates, will now be described. Said means included the hopper 22 for caps, the lower end of the hopper communicating with the relatively short upper chutes 38, 39 and. 40 which conduct the caps to the selecting wheel. The hopper is yieldingly and removably secured to the fixed chute support 4! as by setting the lowermost edge parts thereof into the respective parts of the grooves 42 in the top surface of the support and maintaining the edges in the grooves by suitable spring latches. The chute support receives the upper part 48 of a leg of each of the angle members l6 and is secured thereto as shown in Figs. 1 and 2. As best seen in Fig. 1, the latch handle 43 at the upper part of the hopper is provided with an upper edge or shoulder M urged by the spring 45 into engagement with the fixed cross bar 35 secured to the angle members 41. Similarly, as seen in Fig. 2, the lower part of the hopper is held by similar latches engaging the under side of the cross member of the chute support 41.
Extending from the hopper through and to a point below said support are the cap shutes 33, 35 and All, each of which communicates with a different recess 20 of the selecting wheel when the wheel is at rest whereby caps dropping out of the hopper fall into one of the chutes and thence into 'arecess.
Means are provided for agitating the caps in the chute entrances to prevent jamming of the caps therein. As best seen in Figs. 1 and 4, said extending downwardly from its front edge and having a cam notch 58 therein, being also provided with a rear plate upstanding from its rear edge. The rear plate 55 reciprocates in the space between the front faces of the chutes and the U-shaped guide member 51 secured to the chute support as shown in Figs. 3 and 5. Secured to the front plate 55 and shaped to fit and to reinforce the cam notch 55 is the-cam plate 58 which is engaged successively by the circumferentially spaced cam rollers 59 carried by the selectorwheel and alternately raising the rod holder 5-2 and rods 58 and permitting them to drop under their own weight a number of times oneach revolution of the wheel I9, thereby to keep the caps at the bottom of the hopper in motion and to insure feeding of a cap into each chute.
Since the lateral dimensions or thicknesses of the chutes 38, 39' and 40' are about the same'and the same as that of the cap 33, the hollow open end of the tubular cap may become arranged at the front of the recess 20 or at the rear thereof, it
being required that it be at the front for the purpose of screwing'the cap automatically on to a collapsible tube by suitable means such as the mechanism for capping collapsible tubes disclosed in my copending application, Serial Number 228,829 filed May 29, 1-951, and to which reference is hereby made for a fuller disclosure of the I reversing chute 37 and ofthe means for advancing the cap from the chutes 36 and 3?.
The
selecting arms 23 are therefore designed in connection with the control cams 34 and 35 to cause a cap which is in the required position with its closed end at the rear, to drop into the so-called straight chute 35 and one which is in the reversed position shown in Fig. 8 to by-pass the straight chute and to drop into the reversing chute 3'! which is twisted and consequently reverses the position of the cap as it drops therethrough. As shown in Figs. 1 and 6 both cams 34 and 35 are fixed to the rear face of the rear sheet 60 which is secured to the angle member l6 and which as shown covers the rear sides of all of the recesses 20 except two and also partly covers the adjacent recesses in advance of and succeeding the uncovered recesses, said sheet having a suitable central opening therein for that purpose. The cam 34 has an inner edge groove Bl therein and a rearwardly and downwardly inclined cam surface 52 as is viewed in Fig. 1, the groove for the purpose of by-passing the chute 36 with a cap in reversed position and the latter for controlling release of the cap if it is in its required position.
In operation, the selecting wheel rotates in a counter-clockwise direction as viewed in Fig. 1, so that the pins 32 of the selecting arms ride on the rear face of the cover sheet 60 for the greater part of the revolution of the Wheel. However, as an arm 23 passes the chute 38, the pin 32 thereof drops'off the inwardly projecting edge 53 of the overhanging part of the cover sheet which projects into the greater part of the edge portion of the sheet opening. The spring 29 urges the pin 32 into the recess adjacent thereto. If the closed end of the cap is at the rear, as is required, the front end of the pin then drops onto the closed end surface of the cap in the recess and the arm 23 remains in an inclined position relatively to the rear surface of the wheel as shown by the dash-dot lines of Fig. 8, while the pin presses the cap against the front plate 2! and holds it in its recess.- As the wheel continues itsrotation, the outer end of the arm 23 rides along the inclined surface 62 of the cam 34, thereby removing the pin from and freeing the cap, which then drops by gravity out of its recess and into the straight chute 36 while the wheel is at rest with a recess at the entrance to said chute. As the wheel makes its next movement, the end of the arm 23 rides along the rear face of the rearwardly yieldable by-pass clip 64, (Fig. 6) the free end 65 of which normally rests on the inclined cam surface 56 of the second control cam 35. From the clip 6d, the end of the arm rides on to the rearmost face 5'! of the cam 35 into a-p'osition wherein the front endof its pin 32' is just behind the cover sheet 60, whereby on the next movement of the wheel I9, as the arm end moves off the cam 35, its pin moves on to the rear face of the inwardly extending part 58 of the cover sheet til past the shoulder 69 and remains on said part 58 until it passes the shoulder 63- of said sheet on the next revolution of the wheel.
Should the cap be in areversed positioninits recess 28 as ifl Fig. 8 withits open end arranged at the rear, the pin 32 of the arm passing the shoulder 53 moves under the action of its spring 29 into the threaded interior of the cap to assume th full line position thereof'shown in Fig. 8 in which the arm is substantially parallel to the cover sheet 60. As the end of the arm 23 moves with the-wheel toward the chute- 33, it enters the groove 61 of the-cam 31, the pin preventingthe cap from falling out of its recess and thereby sypassing the chute 36. On the next movement of thewheel, the end of the cap-holding arm 23 rides on to the cam surface 66 of the cam 35 and moves rearwardly enough to withdraw the pin completely from the cap. When the cap reaches the-entrance to the reversing chute, the end of its arm 23 is on the rearmost surface 51 of said cam 35 having snapped past and reaching a position above the yielding free end 65 of the clip 64. The thus freed cap drops out of its recess into the. reversing chute 3'! and is turned around by said chute into the same relative position as the caps falling through the chute 36. On the next movement of the wheel, the pin 32 moves on to the rear face of the cover sheet 60, remaining on the part 68 thereof for a time as already explained.
It will be seen that I have provided simple and dependablemeans for agitating and delivering caps to the cap-feeding chutes, that said means is effective to feed caps in one position into one chute and those in a reversed position to a reversing chute at a difierent point, that by reason of the provision of a wheel with a plurality of recesses therein and a plurality of chutes, the feed chutes are easily maintained full enough to permit continuous further operation without danger of an insufiicient supply of caps and that the mechanism is well adapted to perform its intended functions.
