DESCRIPTION OF PRFERRED EMBODIMENTS:
Referring now to the drawings, there is shown generally at 10, in Figure 1, the packag1ng~machine of the present invent1on f:or packaging two or more cloth articles, such as nylon stockings or panty hose 11 into a plast1c bag conta1nment means 12. The machine comprises two or more, herein three loading conduits 13, having a loading end 14 and a discharge end 15 as is better seen in Figures 3 and ~. The loading conduiks 13 have a trans~
verse cylindrical portion 16 which is a straight pipe portion aligned with a respective one of three discharge containers 16 mountéd on a support turret 17. There are four discharge containers 16 interconnected together in ~IJ~
specific relationship and rotatably displaceable over a s-tationary flat bottom wall surface 18. The containers are open-ended cylinders closed at a bottom end by the wall surface 18. The bottom support surface has a discharge opening 19 therein at a discharge position as indicated by the position of discharge container 16' in Figure l After the discharge containers 16 are loaded with a predetermined quantity of cloth articles 11, they are displaced serially to the discharge position where they are each unloaded, in sequence, by the unloading piston 20. The piston 20 pushes -the articles into an elongated cylinder 21 and at the bottom of which is located the plastic bag 12. This portion of the apparatus will be described later.
As shown in Figure 1, the loading conduits 13 have an exit conduit section 22 which is connected to a vacuum line 24. A valve 25 selectively connects one of the three conduits 13 to the vacuum line, and this is done sequentially by a control circuit 26.
As shown in Figures 6 and 7, when a cloth article 11 is introduced at the loading end 14 of the conduit 13, it is directed by the airflow, indicated by arrows 27, into an open-ended perforated cylinder housing 28 supported in the transfer cylinder portion 16 adjacent the exit conduit section 27. The perforations permit the alrLlow to pass through the housing 28 and the articles to be arrested therein. The housing 28 is an open-ended housing with the bottom open end thereof being supported over a discharge gate 29, which is shown in Figures 6 and :
~ . .
r~,3~
, . .
7 as being in an open condition. All of the gates 29 of each of the transfer cylinder portions 16 are operated automatically and simultaneously by a pis-ton 30 also controlled by the control circuit 26.
After each of the cylinder housings 28 has been loaded with a cloth article 11, the piston 30 is operated to release the cloth article from each transfer cylinder portion, and their ~ssociated transfer pistons 31 are operated whereby their piston heads 32 extend within the transfer cylinder portion 9 and push the cloth article 11 into the discharge container 16 positioned thereunder.
After the piston 30 is reactivated to close the discharge gates 29 the turret 17 is automatically operated by the control circuit to make a 90-degree turn, as indicated by arrows 32 in E'igure 4. The four discharge containers 16 are thus displaced and line up with adjacent transfer cylinder portions 9 of the loading conduits and over the discharge position, as indicated by reference numeral 33 in Figure 4. As can be-seen from Figure 4, once the container 16" has moved in the direction of arrows 32 through two more sequences, it has then been loaded with three cloth articles. It then moves to the discharge position 33 where the three cloth artlcles are dlscharged~
The container 16" at its initial position has a single cloth article therein. After a 90-degree turn a further article is inserted, and then a third article after the next 90-degree turn.~ Accordingly, the containers are loaded ln sequence and discharged one by one, in series, 3 ~ ~ ~
at position 33. If ~our cloth articles were required to be inserted in a bag, then there would be five discharge containers and four loading conduits, and the turret would be displaced in different increments of spacing.
Referring now to Figures 1, 2 and 8, there is shown a bag forming device 40 disposed below and aligned with the discharge position 33 where the container 16' being discharged is located. The bag forming device 40 is of a type known in the art and modified to adapt to the present invention. It comprises an elongated cylinder 21 about which a bag ls formed from a roll of film material 41. As shown in Figure 5, a feed tube 42 is aligned with the discharge opening 19 and extends inside the elongated cylinder 21 concentrically spaced from an inner wall 43 ~.
thereof to form a vent passage 44 therebetween so that air is expulsed -therethrough when the unloading piston 20 is actuated towards its full extended position, as shown in Figure 8. The movemen-t of the product within the cylinder and the bag 12 will cause air to move upwardly through this passage 44.
Once the loading container 16' reaches the discharge positon 33, the control circuit 26 actuates the unloading piston 20 so that its piston head 45 is extended through the feed tube 42 to push the cloth articles 11 through the tube and into the bag 12 formed at the bottom of the elongated cylinder 21. The piston head 45 is then retracted by the control circuit and immediately there-after a clamping device 47 is actuated to clamp the bag with the cloth articles 12 therein to prevent the articles from being drawn out by the retrac-tion of the piston head 45. A sealing bar 46 is then actuated to form a seal at ~, . .
the top end of the bag and at the same time to seal the bottom end of the next bag to be formed. The sealing head 46 is also equipped with a severing means to simulta-neously cut the bag.
As herein shown, the film material 41 is drawn about the elongated cylinder 21 and a side seal is formed by the vertical sealing channel 48. Drive belts 49 positioned on each side of the tube of film material drives the film material downwardly. The drive speed of these drive belts 49 is synchronized with the operation of the packaging head of the machine, and this is also controlled by the control circuit 26.
During the unloading c~cle of the container 16' the loading conduits 13 have all been loaded with a further cloth article. Once the third loading conduit is filled the inde~ing motor 50 (see Figure 4) is operated to move the turret another quarter turn so that the transfer cylinder portlons of the load1ng conduit can be unloaded into the three discharge containers 16 positioned there-.
under, and meanwhile the fourth discharge container 16' isbeing unloaded again.
The method of operation of the packaging machine will now be summarized. Firstly, the control circuit operates the first~ valve 25 of the first loading conduit 13 and a cloth article is introduced at the loading end 14 of that conduit. A photocell, not shown, detects the presence o the article in the perforated housing 28 and .
causes the control circuit to close the valve 25 of the first loading conduit and open the valve 25 of the second conduit where a second cloth article is introduced, and this sequence is repeated between the first to the third .
~ 7 -;~,,f,~
conduits. After all three perforated housinqs 28 are loaded with a single cloth article, -the discharge gates 29 are all opened by the actuation of piston 30. Simulta-neously the transfer pistons 31 eject the articles 11 into a respective one of three discharge containers 16 positioned thereunder. Thereafter, the discharge gates 29 are closed and the loading sequence is repeated with respect to the loading conduits 13. ~uring this loading sequence the turret 17 is operated one-quarter turn to discharge the discharge container 16 at position 16' which has been loaded with three cloth articles 11. The discharge is effected by an unloading piston 20 which pushes thé articles through a feed tube and into a containment means, such as the~plastic bag 12 formed by the bag forming device 40 positioned under the discharge .
position 33 of the turret. Of course, other types of packages may be retained under the discharge position 33 to receive the articles therein, and the stroke of the unloading piston 20 may be adjustable. Also, if the articles 11 have a greater specific gravity, then they would fall into the containment means by their own weight and it may not be necessary to have an unloading piston. -The specific construction of the control circuit and its interconnection with various sensors is quite obvlous to a person skilled ln the art after studying the present description. As herein shown, the control circuit 26 is provided in a housing 50 havlny various switches 51 to~switch the machine on and off. Counters may also be provided on this housing to indicate the number of packages made in a specific time period.
