, 29 Claims.
This invention relates to a method and apparatus for inserting packing in containers and,
more specifically, for inserting packing material in the upper ends of necked containers for tablets or the like to prevent relative motion of the tablets during transportation or movement of the containers with resulting pulverization, or other damage.
It is well known that it is easier to pack pills or tablets in bottles or other containers if the latter are not completely filled by the pills and, furthermore, this facilitates the removal of the contents of the bottles as, if the latter are filled completely up to the necks, it is sometimes rather difficult to shake or otherwise dislodge the first pills from the bottle, the neck tending to trap the pills and hold them against movement.
It is also well known that pills or tablets must be packed and shipped in their containers under little, if any, pressure and that motion of the tablets in the containers must be prevented or otherwise they will become broken, pulverized or their coatings cracked. For this reason, as well as for the reason that it is not desirable to have the containers completely filled by the tablets, it is the custom to introduce into the necks and upper ends of containers a piece of resilient cotton packing which, while pressing lightly on the container contents, holds the latter against undue motion.
The usual method of introducing cotton packing in the upper ends of containers is to out off suitable lengths of cotton strands which are pushed into the bottle by hand, eflicient assembly of the cotton strip leaving a portion thereof near the upper end of the neck where it may be reached for withdrawal when it is desired to use the contents of the container. For large production requiring speed it is relatively impossible to insert cotton packing in this manner so that it will rest uniformly on the material within the conventional type of container and usually the pack ng wads itself on the materials immediately under the neck, leaving the materials under the shoulders at either side of the neck capable of moving so that they are apt to become pulverized, or their coatings cracked. It will be appreciated that in many cases the operator is unable to contrcl the cotton strip beyond inserting it into the container neck and the position and condition of that portion thereof which is below the neck is wholly a matter of chance, in many cases more packing material being pressed into the container than is necessary in an attempt to force the packing away from its position below the neck or otherwise to fill the container below the shoulders.
One of the principal objects of the present invention is to bring about a method of introducing packing within the upper ends of the containers not only in a uniform manner but in such a way that the packing may engage and prevent motion of all of the contents of the container.
A further object of the invention is to bring about a method of insertion and of shaping or forming the packing after insertion wherein a minimum amount of packing material may be used to contact and cover the entire upper surface of the contents of the container and prevent undue movement thereof.
In a more specific aspect it is an object of the invention to bring about a method of introduction of packing in containers wherein the packing may not only engage the contents of the containers immediately under the neck portions of the latter, but likewise under the shoulders at either side of such neck portions.
A feature of the invention resides in the form of apparatus for introducing packing within containers wherein the insertion of the packing by hand methods is eliminated and the packing uniformly and efficiently inserted at all times.
To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.
In the drawings Fig. 1 is a front elevation of a machine for introducing packing in containers according to the invention;
- 1 during the introduction of the packing.
Generally speaking, in carrying out the invention, I prefer to use strips of relatively loose but matted cotton fibers, which strips may be varied in diameter and/or length according to the size of the container or space within which they are to be inserted, the strips being folded or doubled on themselves at points nearer one end than the other, the doubled or folded portions of the strips being inserted into the bottle or container until they contact the container contents, thereafter the branches of the strips above the doubled or folded portions being engaged and carried laterally under the shoulders at the sides of the container necks, the long ends of the strips extending upwardly to points where they may be reached for withdrawal purposes. The method of insertion of the strips may be more fully understood by reference to the preferred form of machine shown herein for illustrative purposes, which will now be described. 7
The reference numeral l8 indicates, in general, a machine capable of carrying out the method described above, the machine I having a frame secured to the upper surface I2 of the table or bench I3, the latter conveniently forming a support for the container I4 herein shown as a bottle, in which the strip |5 of cotton is to be inserted. As described above, the diameter and/or length of the strip I5 will be varied in accordance with the size of the bottle or the space to be filled thereby and desirably is produced by cutting an elongated strip into strips of predetermined length. In any case the strip of suitable length is supported initially on the neck I 6 of the bottle and the pins or studs I1 and I8 extending forwardly from the frame II at either side of the neck I6 and slightly above the same. As shown in the drawings, the strip is placed on the pins and neck with its center at one side of the neck. Mounted for vertical reciprocating motion on the frame II is a crosshead I9 having at its lower end a forwardly extending lug 20 to which is secured a downwardly extending ram 2|, in this case made of relatively thin but stiff strip material, such as steel. The crosshead I9 may be supported for vertical reciprocating motion in guideways 22 and gibs 23. and is actuated by a rod 24 extending downwardly from the crosshead through the bench 3 and pivotally secured at its lower end to a. treadle 25 which in turn is pivotally supported at 26 on the floor 21. A compression spring 28 is telescoped over rod 24 between the crosshead l9 and the bench |3 downward movement of the treadle 25 compressing the spring so that'the release of the treadle 25 will permit the spring to move the crosshead and treadle upwardly into their original positions. Upon the downward movement of the crosshead I9, by means of treadle 25, the plunger or ram 2| engages the strip l5 and carries it downwardly into contact with the bottle neck, the strip being folded by contact with the neck into two branches of unequal length, as shown in Fig. 6, and further downward movement of the ram carrying the strip downwardly into the bottl until its lower end rests lightly on the contents within the bottle.-
Pivotally mounted on the rearward face 28 of crosshead I9 is a pawl 29 having a hook 30 at its lower end which, upon downward movement of the crosshead I9, engages the arm 3| of vertically movable rack 32, the rack 32 meshing with a pinion 33 which in turn meshes with a pinion in a preferably double pointed end as at 39 and 40 and being secured on shafts 36 and 36 in any suitable manner. Upon release of the treadle and upward movement of the crosshead, the hook 30 carries the rack upwardly and thus effects rotation of the pinions, and thus the rams 31 and 38, bringing the pointed ends 39 and 40 into engagement with the folded strip, the pointed ends of the rams engaging the strip adjacent the upper end of the bottle neck and, upon continued rotary movement of the shafts 35 and 36, carrying the strips downwardly into the bottle and laterally under the shoulders thereof, as shown in Fig. '1.
In the specific embodiment shown herein the pawl 29 is pivoted on the crosshead at 4| and provided at either side of its pivotal connection with arms 42 and 43, there being a release pin 44 mounted on the rearward portion of the frame II in the path of movement of the arm 43, the release pin being so positioned as to contact the arm 43 when the rams have carried the packing under the shoulders of the bottle, as shown in Fig. 7, contact of arm 43 with release pin 44 causing the pawl to swing on its pivot 4| to disengage the hook from the arm 3|. The pin 44 swings the pawl against the tension of compression spring 45 mounted between and engaging pawl arm 42 and the crosshead l9, which spring normally holds the pawl in position to engage arm 3|. The rack spring 46, connected at one end to the rack and at its other end to the frame, moves the rack downwardly, upon the release of the arm 3|, to rotate the pinions and withdraw the rams 31 and 38 from the bottle. If desired, the treadle may'be again pressed to bring the ram 2| downwardly in position where it may engage such portions of the strip, especially the longer branch thereof, as may remain above the upper end of the bottle neck to force the same downwardly into position where the bottle may be capped during the subsequent steps of the packing process. It will be understood however that the crosshead is not moved downwardly to the point where the hook engages the arm 3| so that upon release of the treadle the rack and pinions remain idle.
It will readily be understood by one skilled in the art that the amount of movement of the arcuate rams 31 and 38 may be varied by adjusting the position of the pin 44. Thus if the pin is placed in a lower position the rack will be released sooner and with less lateral separating movement of the points 39 and 40 of the rams 31 and 38, whereas if the pin 44 is placed in a higher position there will be more motion of the rack and consequently the lateral separating movement of the ram points 39 and 49 will be greater. In this way I am able to accommodate the machine shown to bottles or other containers of different dimensions. Although I have found that if the pinion centers are spaced two inches apart and the radii of the curved per- 34, the respective pinion shafts 35 and 36 in this instance being mounted at either side of the neck of the container and extending through the frame from front to rear. in the particular machine shown herein the rack and pinions are mounted rearwardly of the frame, the shafts 35 and 36 being elongatedto extend forwardly at least to the position of the bottle. Mounted on shafts 35 and 36 and rotating therewith are rams 31 and 38, the rams 31 and 38 being conveniently formed out of wire or rods bent into arcuate shape, each ram terminating It will be noted that tions of the rams 31 and 33 are substantially V inch the rams, as shown, are capable of handling the packing of practically all the small Sizes of containers now in use, it being but a matter of design to so space the centers of the pinions and the radii of the rams 31 and 38 to accommodate the latter to relatively large containers.
.From the above description of the invention it will be seen that I have devised a method wherein packing material may be uniformly introduced into containers of the class contemplated and spread evenly over the upper surfaces of the entire contents thereof. Owing to the uniformity of introduction I am able not only to insure that the contents of the containers will be held against undue movement after the same are packed, but I am able to accomplish these results w th a minimum amount of packing material.
While I have shown and described a prefe red form of my invention, it is to be understood that the same is not limited to the details shown and described but is capable of modification and variation within the spirit of the invention and the scope of the appended claims.
