Claims. (Cl. 53-135) This invention relates to merchandise packing machines and more particularly to a bagging machine.

One object of the invention lies in the provision of a bagging machine which has a plurality of tubular receptacles each supported for movement about an endless pre-determined path and adapted to receive and support a merchandise bag having its mouth in encircling relation about the lower open end of the receptacle and which after being iilled with merchandise is automatically released and its open mouth secured.

Another object of the invention lies in the provision of multiple vertical tubular receptacles movable about an endless pre-determined path and having closures normally closing the lower end of each receptacle and automatically movable to open positions whereby the contents of the receptacles are discharged into bags having their mouths encircling the open lower ends thereof.

Another object of the invention lies in the provision of a bagging machine having scale supported receptacles wherein the weight of merchandise supported therein is shown upon the scales thus enabling an operator to control the quantity of merchandise to be bagged by sight reading the scale and adding or removing merchandise as required prior to its discharge into the bags.

Another object of the invention lies in the provision of a bagging machine having receptacles, each being provided with an automatically releasable fastener carried at the lower end of the receptacle for initially supporting a bag with its mouth encircling said lower end of the receptacle and adapted to automatically release the bag at a predetermined point along the path of movement of the receptacle.

These and other objects of the invention will become apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designa-te like parts;

Figure l is a view in perspective showing a bank of Ireceptacles and associated elements of a bagging machine constituting the subject matter of the present invention;

Figure 2 is a top plan view of a preferred embodiment of the bagging machine;

Figure 3 is a horizontal cross section through one receptacle as at line 3-3 of Figure 4;

Figure 4 is an elevation showing one end of the machine and disclosing the track in vertical cross section;

Figure 5 is a horizontal cross section taken through one of the receptacles immediately above its movable closure;

Figure 6 is a side elevation of a modified receptacle; and

Figure 7 is a side elevation of the modied receptacle taken on a plane rotated 90 degrees from that of Figure 6.

Referring now more particularly to the drawings, I have shown a bank of vertical tubular receptacles 10, each having open upper and lower ends constituting receiving and discharge mouths. Each said tubular re- Patented Sept. 18, 1956 ICC ceptacle 10 is supported for vertical movement with relation to its mobile supporting frame 11 movably carried upon rollers 12 disposed to roll upon an endless Substantially elliptical track 13.

The track 13 is supported on a frame 14 which rests upon a supporting surface or floor. The frame also carries vertically disposed longitudinally spaced shafts 15, which are rotatably carried in bearings 16 supported on cross braces 17 of the frame 14.

Each shaft 15 is supplied adjacent its upper and lower ends with horizontally disposed pulleys 18V and 19. Endless belts 20 and 21 are trained about the pulleys 18 and 19 and the companion pulleys 18 and 19 of the opposed shaft 15, thus adapting the belts 20 and 21 for movement about an endless horizontal substantially elliptical path. One shaft 15 is provided with a drive pulley 15 about which a belt 22 is trained. The belt 22 is driven from a powered pulley 23 energized by the geared motor indicated by the numeral 24.

The mobile frames 11 are each secured to the upper and lower belts 20 and 21 by means or rivets and are supported in vertical position for movement with the belts about the endless path. Each mobile frame 11 is provided with a horizontally extending ear 25 substantially mid-way its length. Adjacent to the lower end of each frame 11, I provide a horizontally extending U- shaped yoke 26. The ears 25 and yokes 26 extend outwardly of the frame 14, and the yokes 26 have upwardly disposed pins 27 carried by their outer ends.

Mid-way the vertical length of each receptacle 10, l have provided diametrically opposed outwardly extending apertured ears 32, which are adapted to receive the upwardly disposed pins 27 and permit vertical reciprocation of the tubular receptacles thereon.

A second stabilizer rail 28 having a plan shape commensurate with that of the rail 13 is carried by the frame 14 and cooperates with hooks 29 carried by each frame 11 to aid in maintaining the frames 11 in vertical positions. Adjacent to its upper end each mobile frame 11 is provided with a support arm 30. Each support arm suspends a weight scale 31 which supports a companion tubular receptacle 10.

Vertically extending bars 33 are secured to the upper end of the tubular receptacles 10 and have upwardly extending pins 34 which reciprocably pass through the ears 25 of mobile frames 11. Hanging brackets 35 are carried by the bars 33 and are secured to the lower end of the weight scales 31. It will thus be seen that the tubular receptacles 10 and the contents which for the time being may be therein will be supported by the weight scales 31, whereby the weight of the material in the receptacles may be ascertained by sight reading the scales.

To selectively maintain the material or merchandise within each receptacle 10, I have provided a movable closure 35 which comprises a horizontally disposed plate pivoted externally of the receptacle 10 and urged by resilient means 36 into closing relation with the lower end of the receptacle 10. Each closure 35 is controlled by means of a lever 37 which extends outwardly from the receptacle 10 on a horizontal plane and is adapted to strike an abutment wheel 38 thus effectively moving the closure 35 from its normal closing relation with the receptacle to an open position wherein the merchandise within the receptacle is discharged from the open lower end.

Each receptacle is preferably circular in cross section as shown in Figure 3; however, it may be of other shape if desired. To facilitate placing the mouth of a merchandise bag 41 in encircling relation to the lower end of the receptacle, l hinge one side portion 40 of the lower end of the receptacle to the remaining portion by means of a vertically extending hinge 39, thus permitting the hinged portion 40 to move toward and away from the vshown in full line of Figure 6 to the closed rigid portion between the full and the dotted line positions shown inFigure 5, and thereby `makingtlIe-mouth "smaller when in the broken line position. To prevent the hinged Aportion .49 from interfering with the discharge of ,merchandise from the lower end, 'IA provide a depending boss '42 on eachclosure' which strikes the portion '40 shift- 'ing it to 'the outer full time position asthe closure35 is moved to itsopenposition.

Inspection of `Figure 4 will show the .means by which .bags 41 are secured in merchandise 4receiving relation tothe receptacles '10, wherein each'bag 41 is supported 'by a 'fastening means 143, carried .by thelower end of a tubular receptacle. The fastening meanslt comprises a'lever .44pivotally united at 45 to horizontally extending ...ears 46, supported on Vthe receptacle and adapting the 'lever 44 for vertical tilting movement away from the receptacle. A sharp claw .or point 47 is carried by eachllevenand is .movable arcuately about the pivot `l5 intoY position .against the outer'face of receptacle'lt) where it is adapted to support the bag.

The'bag 41 is ofthe type havinga draw string '4S and Vthis draw string is secured to a hook 259 which is pivotally carried by the lower end offrame 11. lt will thus beseen that as the lever '44 is .vertically tilted away from the receptacle 10 to move .the claw or point 47 out of grasping or hooking relation to the upper edge of the .bag 41, the bag by means of the weight of merchandise disposed therein may drop vand hang by the draw string on hook 49 wherein the draw string draws the mouth of the .bag into a closed position.

To effect movement of the'lever t4 to a releasing position, I provide a cam 156, carried by'the'frame'-14 and adapted to strike 'the lever and tilt it vertically to release the bag. As the deviceprogresses about its path, the bags 41 are each carried over a belt .type conveyor C andare 4subsequently released to drop upon the conveyor where they are transported 4to another lplace V for further processing.

Frame 1.4 carries a Ypair of cams 51 and 52 which cooperate to draw the hook 49 in one direction as the draw string 48 is moved Ain the opposite direction, thus releasing the Vdraw string from Vthe hook 49 and permittingthe bag 41 to drop upon the conveyor.

The tubular lreceptacles lil of the present invention are filled -by means of a conveyor, shown in Figure 2 and indicated by the numeral 53, which is timed to supply approximately l0 lbs. of potatoes Vor other merchandise to the receptacle during the time which elapses as each individual receptacle passes the mouth or discharge chute '54 of the conveyor 53. However, an operator will be positioned to add or remove additional merchandise as is shown necessary by Veach weight scale 31. Obviously, as many loading and discharge stations as Vare desired about the endless path, may be supplied, and it is not my intention to limit the-scope of this invention to any particular size, quantity or type of merchandise which is to be bagged by the present machine.

Referring now to Figures 6 and 7 of the drawing, I have shown a modiiied type of closure for the lower open end `of the receptacles 10. The closure in this particular instance is shown to be of the clam shell type, indicated in general by the numeral 55, having 'its two half segments pivotally united to the receptacle 10, diametrically thereof, and movable from the open position position shown in dotted line of Figure -6. Y

'To move the clam shell `closure 55 to the open position, l have provided a pair of links 56 `pivotally united to each clam shell at a point remote .from ,its pivot to the receptacle. The links carry at their upper end a roller 57 adapted to cooperate Vwith a cam 58 supported on the frame 14 of the machine. As the `roller strikes the cam 48 and is lifted, the segments of .the vclam shell 55 are moved to theopen position.

it is necessary .to limit the rupward vmovement .of the r4 receptacle 10 during this function to prevent the lifting motion from vraising Vthe lreceptacle ralso, `and I therefore provide a roller 59 fixed relative to the receptacle 10 and adapted to cooperate with an inverted cam 60, which secures the receptacle 10 against upward movement during the `opening of clam shells 55,

To stabilize roller 57, I provide a vertically shiftable reciprocating rod 61 havingsa-.pair of horizontally spaced vertical rollers V62 on its upper Aend and which bear against the forward 'face of the receptacle 10. The roller 57 has its journal zlxedconthe ,shaft andas v'the roller 57 is lifted by cam 58, the rod Almoves vertically in upper and lower guides 63, carried by'the'receptacle 10.

It will be obvious lto Yone skilledxin the art that the speed of operation of the machine may be such that great or small quantities of materials may be bagged by use of the machine.

.I do not wish to limit myself to the conveyor means of loading 4the receptacles nor `to the conveyor means of removing the loaded bags after release from the receptacles, but lwish to claim -the .invention vbroadly as defined in the instantin View iofclaims and the prior'art.

Obviously, `my device maybe adapted to handle paper and plastic vbags without the drawstrings if desired and to accomplish this, I `provide Utwo spring steel clips at the center and top edges Aof each cam ,section to'hold theemptybags until the weight of the material .therein becomes such as to cause -them rto Vdrop .onto the conveyor belt therebelow.

Having thus describedtmy invention, I claim:
