. 31 charge into the end behind the heat seal, and then heat sealing and cutting off the tube behind the charge. I find that the new heat seal;
for the next bag can conveniently be made at the same time.
The tubular polyethylenesheet is conveniently supplied in a roll as shown in Figure 6.. A suit i adjoining the roll 23 and the feed pipe is placed.
in a vertical position with sufficient inclination to provide gravity feed of material as shown in Figures l and 2. f
For connection tothe feed hopper, the top of the pipe is desirably provided with a funnel 24.
At the lower end of the pipe it is suitably engaged by a spring grip 25 which holds back the mass of crinkled plastic tube and allows the lower end of the tube to feed downward as the weight of each successive charge pulls down on the tube. Thus the lower portion 23 of the tube below the grip 25 is comparatively straight and free from crinkling.
Below the end of the pipe and at one side of the tube are located spaced clamp pads 2'! and 28 on either side of an intermediate slot 30'extending transversely of the tube. The pads 21 and 28 are mounted in a frame 3| which is resiliently'supported on guide bolts 32, the bolts being mounted on asuitably upstanding portion 33 of a machine bed 34. Between the portion 33 of the bed 34 and the frame 3|, the bolts 32 are surrounded by springs 35 which urge the frame toward the plastic tube.
Cooperating with the pads 21 and 28 of the clamp and bridging'the slot 30 is a cushion 33 on the other side of the tube, pivoted at 31 to the upstanding portion 33 of the bed 34 on one side of the frame and, inclosed position as seen in Figure 1, latching at'38 to the'opposite side of the portion 33 of the bed plate. When the cushion is slightly compressed so that the pads firmly grip the tube against thecushion on either side of resisting fabric or elastomer which does not weld with polyethylene. For example, a cotton fabric coated with a commercial silicone oil has been found to be quite satisfactory. Any other well known heat sealing cushion material may be a to be packaged, a length of thermoplastic plastic used.
The lower portion of the frame 3| is recessed at 42 to aid in access to the finished bag by the I ceive guide bolts 43 from guides 50 on the bed, to
. 4 a knife 5| extending across the length of the slot 30. The knife is an elongated metal strip having a cutting face 52 and having end terminals 53. In the preferred embodiment it is made of a suit able electrically conducting metal of relative high electrical resistance, such as steel, Nichrome, or
' bronze.
from their source of air pressure.
The fluid under pressure is received through a main pipe 60 and a pressure regulator 6| to a main control valve 62 in position to be operated in any suitable way. In the illustration shown it has not been considered necessary to mechanize the operation of the valve 62 by the machine and accordingly it is placed for operation by the hand of the operator. Beyond the valve 52 the fluid pipe branches at 63, one branch 58 passing to the air cylinders for the knife as already explained.
Another branch passes to an air cylinder 34 which operates a piston 35 pivotally connected to a lever $5 which is mounted on a fixed pivot 31. Intermediate between the ends, the lever connects to a suitable flexible connection 68 which passes over guide pulleys and connects to a rocker arm ii on a rock shaft '32. The rock shaft carries another rocker arm 13, spring urged by a spring 14 to the position of actuation when nected at 15 to a valve 15 in the bottom of a hopper llccntaining material to be packaged,
pressed into latching position the springs 35 are hand for removal. Spaced at a suitable distance below the slot 33 is the bottom abutment 43 guide the forward and retraction motion of the Mounted on the head 46 at its opposite end sis such as paradichlorbenzene crystals. Below the valve a pipe l3 leads into the funnel 24 at the top of the feed pipe 22. The rock shaft 12 has another rocker 3% which is connected by a link 8| to a rocker 82 on a rock shaft which extends across the top of the hopper and carries agitators 84 in the hopper.
Figure '7 illustrates bag 85 which has been filled with its contents {3 and has just been cut on line 83 and heat sealed on both sides of that 'line.
Immediately above the bag 85 the next bag is partially formed, having been heat sealed at the bottom and having received its charge of material 88 to be packaged.
In operation, with the hopper full of material "considerable amount of plastic tubing can be threaded on the pipe.
The pipe, threaded through the plastic tube, is now placed in position in the machine as shown in Figure -1, and the bottom of the tube is positioned slightly below the slot 30 while the clamp is locked by swinging the cushion into the closed position and engaging it with the latch 38, thus gripping the tube. The valve 32 is then opened, actuating pneumatic or other fluid plung- ,ers 51 to move the knife forward against the tube. The knife is hot due to the resistance heat- ..ing from the electric current, and in a few seconds it cuts the plastic while at the same time the knife sides on either side of the actual cutting edge fuse together the plastic on both sides of the cut. This same behavior will occur whether the plastic is polyethylene or some other thermoplastic plastic such as polyvinyl chloride, polyvinyl acetate, polyvinyl chloricle-acetate, cellulose acetate, cellulose acetate-butyrate, or the like.
At the same time that the opening of valve 62 causes the knife to move forward, the pressure fluid is admitted into the cylinder 64, causing the piston 35 to move up and likewise swinging the lever 56 up at its free end, and allowing the flexible connection 33 to move up under the action of spring 76. This causes the rock shaft to open the valve 16 and to move the agitators 82 in the hopper, so as to discharge a charge of material through the pipe 78 into the funnel 26 and down the feed pipe 22 into the bottom of the plastic tube. The valve in the hopper may be of the measuring type as well known, which will discharge the same charge regardless of how long it is kept open.
As soon as the valve has been open for a sufficient length of time to allow the knife to cut and heat seal the tube, the operator will close the valve, thus causing the knife to retract under the action of the springs in the cylinders 57, and thus causing the hopper valve 76 to close by the action of the spring in the cylinder 64 which moves the piston 65 downward and pulls down on the flexible connection 68 to close the valve 13 and at the same time again agitate the hopper.
As soon as the heat seals have cooled slightly, the operator opens the clamp by releasing the latch 33 and swinging the cushion to the position shown in Figure 2. The bulk of the crinkled portion of the tube above the spring grip 25 does not feed down due to the engagement of the spring grip but the lower portion 25 feeds down under the action of gravity of the charge until it touches the abutment s3, and the lower portion 23 is comparatively smooth and free from wrinkles, but flattened as shown in Figure 2.
The operator now again closes the clamp to make the cutoff and seal at the top of the first bag and the seal at the bottom of the next bag, and opens the valve 62, causing the knife to move into contact with the tube, cutting it and heat sealing at both sides of the cut. At the same time the air cylinder 64 causes the hopper valve to open and deposit a charge of material to be packaged in the bottom of the next bag. As soon as the valve 62 is closed the knife retracts and the hopper valve closes. The bottom of the tube is then in the condition shown in Figure 7, the bottom bag 85 being fully heat sealed and just cut off and the next bag having received its heat seal immediately above the cut line 86, while the next charge has entered the bag above. There are thus two charges, 81 in the lower bag and 88 in the upper bag.
It will be evident that while the charge 88 above the out comes down while the cut and heat seals are being made, due to the clamping the weight of this charge is not borne by the upper heat seal until after the clamp is removed. Therefore the heat seal by this time is somewhat cooled and therefore stronger.
As soon as the clamp is opened, the lower bag is removed from its position on the abutment 43 and dropped through opening 44 into the dis-' charge chute 45. Due to action of gravity under the Weight of the charge 88, the forward or lower end of the tube now moves downward un' til it contacts the abutment Thus the feed ing of the plastic tube is accomplished by the combination of the gravity action on the charge and the retarding action of the spring grip 25. The next operation can then begin, by again closing the clamp, opening and then closing the valve 52, opening the clamp, removing the lower bag, and allowing the next bag to feed under gravity action.
It will be evident that by the present invention it is possible to package a large number of bags with any suitable material, preferably a dry granular or powdered material, and the invention is therefore applicable to a wide variety of plastic packaging tubes and materials to be packaged, although it is primarily intended for use in obtaining a vapor permeable package of paradichlorbenzene by flexible polyethylene sheet.
Itwill be evident that while a flexible polyethylene bag is fully permeable to the vapor of paradichlorbenzene it is otherwise'hermetically sealed, and therefore will not accumulate moisture or allow escape of solid material.
The bag is at the same time so soft'and convenient that it can be readily used as the manner of a sachet bag to intersperse among clothing and provide protection against insects, particularly moths.
In view of my invention and disclosure variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the process, machine and product shown, and I, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claims.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. An insecticidal article which comprises: (1) a sealed bag of polyethylene sheet which freely passes the vapor of paradichlorbenzene and (2) solid paradichlorbenzene in the bag, the vapor of the paradichlorbenzene passing freely through the bag and entering the air around the bag, the polyethylene sheet being exposed freely to the atmosphere on the outside and to the paradichlorbenzene on the inside.
2. An insecticidal article consisting of (1) a tube consisting of polyethylene sheet having fused seals at both ends and (2) paradichlorbenzene inside thereof, the polyethylene sheet being exposed free to the atmosphere on the outside.
3. The use of a sealed polyethylene envelope, freely exposed to the atmosphere on the outside, and having paradichlorobenzene on the inside, to inhibit insects in places outside of said envelope.
