This invention relates to a packaging machine, and more particularly to a packaging machine in which an endless chain on which are mounted upstanding fingers is provided for the reception of a continuous supply of open bags, preferably of cellophane or Pliofilm, which endless chain presents the bags to a filling hopper at which point the bags are filled and removed from the chain, being conveyed therefrom to a checking station.

While the invention is adaptable to a more general use, it has been found particularly useful in the packaging of dried fruits.

It is accordingly one object of this invention to provide a packaging machine of the type described in which bags are continuously and automatically presented to a filling hopper and filled with the article to be packaged. It is another object of this invention to provide a packaging machine of the type described in which the filled bag is automatically removed from the initial bag holder and carried by suitable mechanism from the filling hopper.

These and other objects and advantages of the invention will be apparent from, the annexed specification, in which:

Figure 1 is a side elevation of the packaging machine;

Figure 2 is an enlarged fragmentary side elevation of the machine shown in Figure 1;

Figure 3 is an enlarged section taken on the line 3-3 of Figure 2;

Figure 9 is a section taken along the line 9-9 of Figure 8;

Figure 10 is an enlarged section taken on the line Ill-IE3 of Figure 2;

taken along the line taken along the line taken along the line Figure 11 is an enlarged perspective eleva tion of the roller chain and bag-carrying fingers in one position of its travel;

Figure 12 is a perspective elevation similar to Figure 11 showing the mechanism in a further position of its travel;

Figure 13 is a perspective elevation of the mechanism shown in Figure 12 showing the filled bag-carrying mechanism in a further position of travel; and

Figure 14 is a perspective elevation similar to Figure 13 in a still further position of travel.

Referring now more particularly to the drawings, the mechanism comprises a frame comprising identical front and rear frame members, only one of which is shown in Figure 1 and described. Each side of the frame includes a horizontal member 28, shown in Figure 2, as composed of a pair of angle bars 29a forming a channel and also upright angle bars 2|, 22, 23, 24, 25, 26, 21, 28 and 29. The frame also includes a further angle bracket 30 and another angle bracket 3! formed as indicated. As in the previous case, other angle brackets similar to the angle 1 brackets 30 and 3! are disposed on the otherside of the machine.

Mounted on a top piece 32 is a suitable source of power, such as the electro-motor 33, which electro-motor is provided with a sprocket 3'5 driving a chain 35, which chain leads to a sprocket 36. Sprocket 36 carries a gear 31 driving a gear or sprocket 38. A roller chain 39 engages the sprocket 33, which chain 39 is conveyed as hereinafter described adjacent the angle brackets 38 and 3| and engages the sprocket 42. A further roller chain ll is driven by a suitable gear or sprocket mounted on sprocket 36 and is led by means of

idlers

42, 43, 44, i5, 46, and 4'! to a sprocket 48. The chain 6| is maintained under tension by means of the adjustable sprocket or gear G9. A further roller chain 53 is provided engaging the sprockets 5! mounted upon the shaft 5| of the sprocket 48. The chain then passes over the idlers 52 and the sprockets 53. It will be ap parent that the motor 33 thus drives the chain 39, the chain 4!, and the chain 58. The chain 58 is a double chain, as shown in Figures 11-14 and hereinafter described.

Angle brackets

54, 55 are provided in the framework, it being understood that the

brackets

55 and 55 are again duplicated on the other side of the machine. Similarly,

angle brackets

56 and 51 are provided which, with the complementary members, complete the framework of the machine.

Referring now particularly to Figures 11, 12, 13 and 14, the roller chain 50 is indicated as in fact comprising a pair of chains 59a and 59b, and at suitable intervals the chains are connected, as by means of angle brackets 58, to plates 59. The plates 59 are U-shaped, having their ends bent upwardly as at 655 and 81 forming fingers, indicated generally by the numeral 62. The frame member 54 carries a pair of upstanding angle members 63 and Ed on which are mounted an- 3

gle brackets

65 and 66 to which are attached the rails 61 and 63 upon which the rollers of

chains

50a and 5% travel. A cross angle bar 64a is provided for rigidity.

At the point of travel of chain 58 opposite the member 64, the chain 53 is thus depressed, forming a slight curve causing the fingers 62 of two successive plates 59 to be tilted inwardly towards each other as clearly indicated in Figure 5. At this point an operator is stationed who places a cellophane or Pliofilm bag over the fingers 62. As the chain progresses, it straightens out and as the chain 50 passes over sprocket 53, the fingers 62 tend to separate, thus firmly gripping the bag as it is inverted. After passing over the sprockets 53 the chains 53a and 53b engage rails similar to the rails 6'! and 68 mounted in the angle bars I60 in a manner similar to the mounting of rails 6! and 68 in the

angle bars

65 and 66 and from there rails pass to the sprockets 5|.

The chain 39 is a single chain and supports a bag holder as most clearly shown in Figures 6, 7, 13 and 14. The chain 39 at suitable intervals is provided with pairs of side plates 12 to which are riveted a bag holder :3. The bag holder 13 comprises a bottom portion 74, an end portion 75, and a cross piece 16 which has ends 11 bent at right angles thereto and curved outwardly as at 18. The angle members 3i are spaced apart. Thus the angle members 3! form a support upon which ride the plates M, and, similarly, the angle member 36 provides a supporting surface for the plates. 14 in inverted position, and thus the angle members 30 and. 3| define the path of the chain 39.

Referring now to Figures 8, 9 and 10, it is to be noted that a hopper 80 is provided having an elongated opening 80a, which opening is disposed above and in the line of the path of the bags secured to the fingers 62 with the bags in the inverted position and supported in the bag holder 13. The hopper 80 has a pair of end members 8! and a pair of oppositely inclined bottom members 82 and 63, the member 83 being shorter in width than the member 62. A tube 84 is welded in brackets 85, which brackets are riveted to the end walls 8|, and a similar tube 36 is welded to the bottom 82, as indicated, and a length of pipe 81 is provided joining the tube 86 and secured to the frame member 21' as at 88. The tube 84 serves to stiffen the hopper 30, and the tube 86 and pipe 81 serve to support the outer end thereof from the frame 27. One of the end walls 8i toward the motor end of the machine has a substantially semi-circular opening 96 therein.

The operation of the machine is as follows: Assuming the hopper 86 to be filled with substance to be packed in the bags 79, such as dried fruit or the like, and the motor 33 to be turned on, the chain 35 will drive the sprocket 36, in turn driving the sprocket 38 and the chain 39, as well as the chain 41-. The chain 4| in turn drives the sprocket 48. and also the sprockets 51 and accordingly the chain 50. The gear ratios are suitably proportioned so that the chain 50 and the chain 39 operate at the same velocity. An operator is stationed opposite the angle bar 64 and places open-ended cellophane or Pliofilm bags with the open end down over the fingers 62. Bags are then carried, as indicated in Figure 2, over the sprockets 53 and inverted. As the bags are inverted they are engaged by the bag holder 13 mounted upon the chain 39 and as they come into alignment with the elongated opening a in the hopper 86 the bags are filled With the dried fruit. It will be appreciated that the fingers 62 still remain inserted in the bags 76 as the bags are being filled, and the plates 59 serve to close all parts of the elongated opening 86a of the hopper except the portion directly over the bags being filled. The fingers 62 in the region opposite the angle bar 64 are converging, which facilitates the placing of the bags 10 thereon. While in the region of the sprockets 53 the fingers 62 assume radial positions and hence are diverging and serve to support and retain the bags 70 during the inverting thereof, however after leaving the sprockets 53, the chains 50a and 56b engage the rails mounted in the angle bars which are substantially straight and hence the fingers 62 assume a parallel position. As the bags progress from their position underlying the hopper the paths of the

chains

39 and 50 diverge, as clearly illustrated in Figure 2, and as the paths of the two chains diverge and the fingers 62 are then in parallel position the fingers 62 are withdrawn from the filled bags which remain in the bag holders '53 as illustrated in Figure 14.

The bags having been filled, they then travel in the bag holders T3 on the chain 39 where they may pass a checking station where operators may weigh each individual bag on the scales H3 in order to assure that each bag is filled with a suitable weight of dried fruit. After being checked the bags may be replaced on the bag holder 13 where they are passed in alignment with a bag sealer l 15 for sealing the open end of the filled bags. It will thus be appreciated that by means of this invention the bags are presented to a filling station, filled, checked and sealed in one continuous operation.

While there has been described what has been considered the preferred embodiment of the invention, it will be appreciated by those skilled in the art that various changes and modifications may be made without departing from the essence of the invention, and it is intended to cover herein all such changes and modifications as come within the true spirit and scope of the appended claims.
