30 Claims.

The invention relates to new and useful improvements in bag closing and fastening machines and has 4particular reference to mechanism for fastening the folded portion of a filled bag by means of a tin-tie strip.

The structure of the invention has application to bag closing/machines of the semi-automatic type and also to fully automatic machines for filling and closing bags such as shown in the application of George Long and Elwell B. Larsen, Serial No. 87,972, led June 29, 1936.

Machines of the above identified type employ conveyor mechanism for intermittently moving bags from station to station through a plurality of stations comprising the machine. In the semi-automatic machine the illled'bag is first gauged as to height'to bring the contents of the bag to a predetermined level. At subsequent stations the open end of thebag is collapsed, folded and then the folded portion is releasably fastened to the bag by tin-tie fastening means. The structure of the invention is adapted to accomplish this last operation in a new and improved manner. More particularly, the novel structure of the invention is characterized by means which lift the bag and hold the same at an angle so that the folded portion will assume a horizontal position and by members operating conjointly with said means for bending the projecting ends of the tin-tie strip to form the fastening elements described.

A more specific object of the present invention resides in the provision of improved mechanism for the purposes described, which will intermittently feed acontinuous length of tintie tape to locate the forward leading end of the same over the folded portion of a filled bag and which will thereafter cut the tape to form individual tin-tie fastening strips, the cutting operation providing fastening strips of a lengthgreater than that of the bag so that the projecting ends thereof may be subsequently bent around the folded portion of the bag, thus securely fastening the folded portion and preventing it from becoming unfolded.

Another object of the invention resides in the provision of bag closing and fastening mechanism having novel structure for feeding continuous tin-tie tape and which will automatically cut said tape into individual fastening strips after the same has been properly associated with the folded portion of a filled bag. In accordance with the invention the continuous tape has a width of paper secured thereto which is blanked out at intervals-forming paper tabs between the blanked out portions, a tab being centrally disposed with respect to each tin-tie fastening strip above described, and each tab being adhesively secured to the top of the bag as the last operation in the closing and fastening thereof.

Another lobjectresides in the provision of mechanism for the purposes described which will operate in sequence to apply a tin-tie strip over the folded portion of a filled bag, to bend the ends of said strip around the folded portion of said bag to fasten the same in secure folded relation, and to adhesively secure the tab associated with the tin-tie strip to the top of the bag. This last operation of adhesively securing the paper tab to the bag results in making the tin-tie strip a part of the bag so thatthe strip is retained to the bag even though the bent ends are subsequently released from their fastening relation in order to permit removal of the conto the folded portion of a filled bag and means operating conjointlytherewith for bending the projecting ends 4of said strip to form releasable fastening means holding the folded portion to the top of the bag, which will be comparatively simple in its construction and arrangement, strong and durable, and which will be thoroughly eilicient in use, automatic in operation and relatively inexpensive to manufacture. With these and various other objects in View the invention may consist of certain novel features of construction and operation, as will be. more fully described andparticularly pointed out in the specification, drawings and claims appended hereto.

Figure 17 is a plan view showing the ccntinuous tape and the manner of cutting out portions from the paper strip to form the individual tin-tie strips.

Referring to the drawings, particularly Figures l and 3, the structure of the invention is adapted to perform the last operation in the closing and fastening of a filled ba'g when said fastening is accomplished by a tin-tie strip and accordingly it will be understood that a complete machine, for example, of the semi-automatic type, will include means for gauging the height of the filled bag to bring the contents thereof to a predetermined level, means for collapsing the open end of the bag, and means for folding said collapsed end to form a folded portion which will project vertically from the top of the bag. Following the last folding operation the bag is then presented to the apparatus of the present invention, which preferably depends from an overhead member identified by numeral I0 supported from a plurality of uprights such as II. Secured to the underside of the supporting member I0 are a plurality of brackets I2, I3 and I4, which brackets form means for journalling shafts to be presently described. Actuated by said shafts are instrumentalities of novel construction which perform the necessary operations to apply a tin-tie to the folded portion of the bag and bend the ends of the same into fastening position.

The guide I5, providing upper and lower mem bers I6 and I1, respectively, having the groove I8 therebetween, is suitably supported from the overhead support I0 by the screw member I9. The continuous tape 20, Figure 17, Comprising the metal strip 2I and the paper strip 22 secured thereto is adapted to fit within the groove I8 of the guide I5. Said tape prior to entering the groove may pass through straightening rollers 23, it being understood that said tape will most likely be supplied in the form of a large roll and therefore said straightening rollers will have the effect of substantially eliminating the curvature which would otherwise exist in the tape. The metal strip 2I of the tape is located in the base of the groove, as clearly shown in Figure 4, which thus makes possible the cutting out of portions of the paper strip 22 to form tabs 24. Cutting of the paper strip is effected by the rectangular knife member 25 pivotally supported at 26 and suitably actuated by rod 21. The knife 25 is adapted to operate within a substantially square space 28, Figure 9, formed in the guide I5, it being understood that the several edges of the knife will be approximately parallel to the ad-l jacent edges of said space. Positioned centrally of said space is a backing member 30 suitably supported from the upper member I6 of the guide in a manner to permit yielding movement of the backing member. Said backing member is somewhat smaller than the knife and by reason of the bent portion 3I the said knife may travel in an upward direction some distance past said member. Oscillating movement is imparted to the knife 25 periodically by actuation of rod 21 and accordingly it will be understood that substantially square portions are cut out of the paper strip 22.

At the forward end of the guide I5 there is located means 32 for applying an adhesive such as glue to the undersuriace of each tab 24. Also located to the forward end of the guide is mechanism 33, Figure 2, for severing the continuous tape along a line 34, Figure 17, which approximately coincides with the center of the cut out portions in the paper strip. This structure will now be described.

As shown in Figures 1, 2 and 4, the member I1 supports by means of brackets 35, a member 36 to the forward end of which is suitably secured the block 31, forming part of the cutting mechanism indicated in its entirety by numeral 33. At its rear end the member 36 is provided with a cam-shaped slot 38 having pin 39 fitting therein, which is secured to the upper projecting arm of the bell crank lever 40. The lower arm of said lever is provided with pin 4I adapted to contact the extending end 42 of the lever 43 suitably pivoted at 44 to means depending from the guide I5. The forward end 45 of said lever is operatively associated with the cutting knife 46 suitably secured to block 31 by means of the face plate 41. The knife 46 is adapted to operate with respect to a stationary cutting blade 48.

In operation of the structure above described, it will be assumed that a length of tape 20 has been fed from theforward end of the guide I5. This feeding of the tape forwardly will bring the paper tab 24 into Contact with roller 50 of the gluing mechanism 32 suitably driven by the driv ing chain 5I through meshing gear 52. The rod 53 is then suitably actuated to cause rotation of 75 the bell crank lever 48 which will cause forward movement of member 36 by reason of the pin 39 riding in slot 38. The cutting mechanism is therefore located a short distance forwardly of the end of the guide I5. As the bell crank-lever 48 nears the end of its oscillating movement, the pin 4| will strike the end of lever 43 to cause downward movement of knife 46, which actuation of the knife will sever the continuous tape 28.

As previously explained, the tape will be cut along a line substantialy coinciding with the center of a cut-out portion of the `paper strip.

The mechanism for intermittently feeding the continuous tape to locate a length of the same directly over the bag is shown in Figures 6, '1 and 8. Journalled in the depending 'brackets I3 is the shaft 54 having suitably xed to one end thereof the arm 55 to the outer end of which is pivotally secured the actuating rod 56. The hub member 51 fixed to shaft 54 and locatedbetween the brackets I3 is formed with an integral depending leg 58 providing at its extreme lower end a gripping finger 68. Having reciprocating movement on leg 58 is a sleeve 6| which likewise provides a gripping nger 62 and which is actuated in a direction toward and from the lower finger 68 by means of a toggle joint formed by

arms

63 and 64, the latter being pivotally secured to leg 58 at 65.- To the upper freeend of arms 64 is pivotally secured link-, 66 which joins said arms of the toggle to spool 61provided wthgroove 68. Saidspool is slidably mounted on shaft 54, being yieldingly forced in a direction toward the left by the coil spring 18 located on the shaft and positioned between hub 51 and said spool. Actuation of the spool in a direction toward-the right, which will straighten the toggle and force finger 62 toward finger 68, is effected by the yoke 1| pivoted at 'I2 and having its bifurcated lower end operatively associated withthe spool 61 by means of groove 68. Oscillating movement is imparted to the toggle which forces the upper fingerl62 in a direction downwardly, thus gripping the said projecting end of the tape. oscillated in a direction toward the left, Figure 1, to thereby cause feeding of the tape and the locating of a length of said tape directly over the bag 15. In accordance with the invention'the leading end of the continuous tape is positioned by the gripping fingers a short distance beyond the side of the bag, which centrally locates the paper tab 24 with respect to the top of the bag.'

The next operation, which occurs substantially simultaneously with the feeding of the continuous tape, is performed` by mechanism shown in Figures `5, 10, 11 and' 12. The brackets I2, dependingfrom the member I8, suitably journal at their lower ends the shaft 18,@to the outer projecting ends of which are suitably fixed depending arms 88. The projecting end 8| of shaft 1 8 is reduced in diameter and slidably mounts the double spool 82 having grooves 83 and 84 formed therein. The depending arms 88 journal at their lower endthe member 85 having an' oiIset portion The fingers are then 86 located between the depending arms 88 and which portion provides the gripping member 81. Extending through the journalling ends of member 85 and projecting from the ends thereof, Figure 12,- is a shaft 88 adapted to have axial movement and forme'd with spaced slots 89. The offset portion 86 of member 85 is also provided with a slot within which is pivotally supported for oscillating movement the pawl 98T The respective ends of the portion 86 areV formed with upstanding journalling means 9| supporting therebetween. the pivot rod 92 which pivotally supports member 93 having an arcuate shape centrally thereof and the depending lower end of which forms a gripping member 94. Movement of gripping member 94 toward and from member 81 is effected by the pawl 98, one end of which, as described, has connection with Shaft 88 and the other end of which engages plate 95. The pins 96 xed to said plate pass throughportion 86, through slots 89, in shaft 88 andare xedly secured at their opposite end to the arcuate por# tion of member 83, as shown in Figure 12. The coilsprings 91, carried by the pins 96 and which are located between member 93 and shaft 88, serve to yieldingly bias the member in a direction outwardly, thus spacing gripping member 94 from member 81.

However, the gripping members are caused to close so as to grip the upstanding portion 16 of the bag, Figure 3, by axial movement of shaft 88 in a direction toward the left, Figure 12. This movement is caused by actuation of lever |88 pivoted at |8| and having operative connection at its lower end with s rool |82 xed to the end of shaft 88. The upper end of lever |88 is associated with spool 82, by means of slot 84 formed therein, and upon movement inwardly of said spool, which movement is caused by actuation of lever |83, the shaft 88 will be caused to travel in a direction toward the left. This will rotate the pawl- 98 in the proper direction to cam plate 95,

yforcing the plate outwardly and thereby causing movement of gripping member 94 inwardly toward member 81. Lever |83 is xed to shaft I 84 journalled in bearing I4, Figure 1, as is also lever |85 to which is secured the actuating rod |86.

After the upstanding folded portion 16 of the bag has been gripped by members 81 and 94 said members are oscillated and simultaneously bodily rotated so as to locate the folded portion in a substantially horizontal position and adjacent the tin-tie strip. As shown in Figure l0, the end of Vmember 85 opposite spool |82 has suitably secured thereto lever |88, carrying the roller |89. The coil spring ||8,con1ined between said lever and the depending arm 88, yieldingly biases the' member 85 in a direction whereby the gripping member 81 will be depending vertically downward. Yieldingly forcing the member 85'in this direction will cause the roller |89 to contact the stationary bar I||, Figure 3, which acts as a stop to control the rotary movement of member 85. However, the entire assembly hasA oscillation in a counter-clockwise direction, Figure 5, after the gripping membersl engage the up.

standing folded portion of the bag. This oscillating movement is accomplished by means of a lever II2, Figure 10, suitably actuated by the rod II3, said lever having connection to an arm 88 whereby it will be understood that the assembly toward the stationary anvil II4, Figure 11. Said 7.5

anvil provides a flat surface I5 extending for the width of the bag and a shoulder ||6 adapted to have contact with the metal strip 2| of the continuous tape to thus hold the tape properly aligned with respect to the anvil. As a result of the counter-clockwise oscillating movement of the assembly comprising the gripping members, the same is swung toward said anvil and simultaneously said gripping members are rotated. This rotation takes place against the tension of the coil spring ||0 and results by reason of the fact that roller |09 is in contact with stop Following the labove operation on the folded portion of the bag the continuous tape is cut by the

knife blades

46 and 48 along line 34, the cutting mechanism immediately receding following the cutting operation and thereby leaving a portion of the tape projecting beyond the same and which will be readily gripped by the gripping fingers 60 and 62 at the start of the next operation of the machine. It will also be understood that cutting of the tab along line 34 will leave the rear end projecting beyond the side of the bag which together with the forward projecting end of the tin-tie will form the fastening means for releasably securing the folded portion to the top of the bag. As shown in Figures 5 and 13, the gripping members 81 and 94 hold the folded portion in a position horizontal and adjacent the tin-tie strip which is held in contact with the anvil H4. More particularly it will be observed that member 81 is located between the tin-tie strip and the folded portion of the bag.

The projecting ends of the tin-tie strip are bent into a fastening position by fingers |20, each having pivotally secured thereto a link |2| having a pivotal connection at |22 to the anvil H4. Pivotally secured to the upper end of each finger |20 is a lever |23 suitably fixed to shafts |04 journalled in bearings |4. Also fixed to each shaft |04 is an arm |24 having pivotal connection with the operating rod |25 which is actuated in synchronism with the other operations of the machine to oscillate levers |23 which will cause said lingers |20 to travel downwardly from the position shown in Figure 1 to the position shown in Figure 13, whereby the projecting ends of the tin-tie strip will be bent around the ends of the folded portion 16 and under the adjacent top side of the bag. In order to allow the bent projecting ends of the tin-tie strip to contact the underside of the topof the bag it will be observed, Figure 13, that the gripping member 94 has a width less than its companion member 81. The bending operation on the projecting ends of the tin-tie strip takes place while the folded portion of the bag is held in horizontal position by the gripping fingers 81 and 94. The next operation of the mechanism withdraws said gripping fingers by oscillating the entire gripping assembly in a clockwise direction, which is effected by upward travel of the lever l2, actuated by rod ||3. Although the assembly is given oscillating movement the gripping iingers-maintain a horizontal position while being withdrawn. This is permitted since member is free to rotate in either direction, however, being biased by the coil spring ||0 so that the gripping finger 81 will depend vertically. When the gripping fingers have been withdrawn to the extent where they leave the folded portion of the bag the operating rods |25 are again actuated to cause the fingers |20 to pinch the bent ends of the strip, securely fastening the folded portion to the top of the bag.

The last operation in the closing and fastening of the bag is to cause the paper tab 24 to adhere to the top of the bag. As previously explained, an adhesive is applied to the underside of said tab during the feeding of the tape to locate a length of said tape over the bag. The structure above described has been designed so that the paper tape will be centrally positioned with respect to the bag and since an adhesive has been previously applied thereto, it is only necessary that said tape be forced into contact with the top of the bag. This is accomplished by the member |28, Figure 16, having a rounded portion |29 at the lower end thereof. rlhe upper end of said member is suitably fixed to rod |30, pivotally supported by shaft |3l, journalled in bracket |32. The coil spring |33, conned between rod |30 and one arm of said bracket yieldingly biases said member |28 in a direction inwardly, Figure 3, where said member will engage a stop, locating the same in a vertical position. Bracket |32 is provided with an upright portion |34 having formed therein an elongated slot |35. The support |36 is suitably secured to the underside of member' l0 and it will therefore be seen that the bracket and member pivotally supported therefrom are mounted for vertical reciprocating movement, which is imparted thereto by actuation vof lever |31.

While the folded portion of the bag is still held by fingers |20 the lever |31 is caused to move downwardly and accordingly similar movement will be given to the member |28. The rounded portion |29 of said member will be caused to contact and travel over the .paper tab |24, it being understood that continued downward movement of member 28 will cause the same to travel outwardly, which travel is permitted by reason of the pivotal support of said member. The effect of this travel of the end |29 of the member over the paper tape is to roll said tape into contact with the top of the bag, which adhesively secures the tin-tie strip' to the bag.

'I'he fingers |20 are then retracted through actuation of the rods |25 and the bag is released, whereby the same will slide downwardly on the upright |26, Figure 5, and will again assume an upright position.

The gripping members in bending the upstanding folded portion of the bag into a substantially horizontal position simultaneously locate the7 said folded portion adjacent to the tin-tie strip and also lift thenag and incline the same from the vertical. The upstanding portion of the bag is bent substantially and the fiat surface thereof is located in a plane substantially parallel with the flat side of the tin-tie strip. The lifting of the bag by the present apparatus, and wherein the bag is tilted with respect to the vertical, is responsible for a number of desirable features which are peculiar to the present method. In the rst place, the bag is suspended by the gripping members 01 and 94 which engage and bend the folded portion sothat the weight of the bag provides adequate clearance under the top sides of the bag for the nngers |20 which bend the ends of the tin-tie strip around said Ifolded portion and under one top side of the bag.

|20 to readily bend the ends of the tin-tie tape under said top side of theV bag, whereby vthe bent folded portion is releasably fastened to the top of the bag.

The following operations arev performed While the bag is thus held by the gripping members. For example, the ends of the tin-tie strip are bent downwardly and inwardly around the ends of the folded portion and under the top of the bag, thereby releasably securing said folded portion of the bag and'further, the paper tab is adhesively secured to the top of the bag, this latter operation only requiring travel of member 28 over the paper tab to force the same into contact with the bag since adhesive such as glue or the like was applied to the undersurface of said tab during the feeding movement of the said continuous tape.
