11 Claims.
My invention relates to apparatus for supporting and distending bags to'facilitate filling with an article to be packaged thereby.
The principal object of my invention is to provide an apparatus supporting a stack of bags in a suitable manner whereby an article may be moved into the apparatus and emerge therefrom suitably contained within a bag.
I accomplish these and other objects and obtain my new results as will be apparent from the device described in the following specification, particularly pointed out in the claims, and, illustrated in the accompanying drawing, in which- Fig. 1 illustrates a mans shirt, shownin dotdash, being inserted into the bag distending apparatus, shown in perspective view, and emerging therefrom inserted in a bag having a transparent top.
Fig. 2 is a top plan view of my apparatus, some of the elements thereof being shown in dotted lines.
Fig. 3 is a longitudinal sectioned elevational view taken in the plane 3-3 of Fig. 2.
Fig. 4 is a transverse sectioned elevational view taken in the plane 4-4 of Fig. 3.

Fig. 7 is a partial sectioned plan view taken in the plane 1-1 of Fig. 3.
Fig. 8 is an enlarged partial sectioned view of the bag supporting end of the apparatus illustrated in Fig. 3, with the top bag distended.
Fig. 9 is a longitudinal sectioned view, similar to Fig. 3', of a modification of my apparatus.
Fig. 10 is a partial view of the driving mechanism for the modification of Fig. 9.
Referring to Fig. '1, reference numeral Ill designates a frame made of wood or other suitable material for supporting the various elements of my apparatus, and consists of end walls II and I2, joined by longitudinally extending side walls l3 and I4. An intermediate wall It; transversed extends across the housing for supporting a tongue [6, and corner guides I! hereinafter described in detail.
A bag holder 3 is pivotally hinged at I9 to the end wall I l and supports the bags 20 thereon as is shown in Fig. 8. A resilient pressure plate 2| is positioned beneath the bag holder l8 and is provided with'a cam. 22 atone end and a hinge 23 at the. other for pivot support on end wall Beneath the pressure plate, apressure shaft 24 2 extends, upon which is mounted a pressure cam 25. The shaft is supported on bushings 26 mounted on the inside of walls l3 and M and extends through an aperture 21 in wall M to terminate in a handle 28.
Lifting the handle 28 causes the cam 25 to ride under pressure plate 2| forcing cam 22 to lift the pressure board I8 and. apply a resilient pressure to the bags, the lips 29 of which are caught under tongue It as shown in Fig. 8.
Extending upwardly from the outside of wall H is a back stop 39 which is centrally positioned and curves slightly above the ends of the supported bags to hold the bags in position and prevent their endwise movement until they are in fiated. This again is bestshown in Fig. 8.
Upon the upper surfaceof the bag holder l8 are positioned two convexly shaped lateral supports 3| which extend longitudinally in spaced apart parallel position, as is shown in Fig. 2 and Fig. 4. When the bags are supported on the bag holder, the two sides of the bags are upwardly arched by supports 3| and cause the bags to assume a concave position. I have found that supporting the bags in this position gives them greater rigidity and permits one bag to slide on another when removed without buckling.
When a stack of bags are placed upon the bag holder and caught in position under tongue It by turning handle 28, the two corners of the bags at the open end are also caught under the corner guides l'l. This construction facilitates the release of one bag at a time under the inflating pressure caused by the blower 32 when driven by the motor 33, see Fig. 2. The nozzle 34 of the blower is directed above and along the chutelike tongue I6, as shown in Fig. 3, and causes a jet of air to be directed towards the upper bag, the upper lip of which is freed from the tongue to allow the bag to distend. v
The inflated bag 35 takes the position shown in Fig. 8, around the ends of two juxta-positioned distending funnels or chutes 36, hingedly mounted to pivot shafts 31 by rivets 38. The shafts, bearing on angle plate 39, are biased toward each other by spring 40. The free ends 4| of the funnels consequently arepulled towards each other until the rear edges 42 engage the upper connecting angle plate 39 forming a stop for the inward movement of the funnels.
Thus a shirt 43, as an example of an article to be covered by the bag, as is shown in Fig. .1, and preferably folded about a 'shirtlboard, not shown, to hold its position, may be propelledby hand through the enlarged ends of co-acting funnels 36 and against the pressure of spring 40, forcing the narrowed ends M of the funnels to engage and distend the ends of the inflated bag 35 and hold it securely while the shirt is moved into the bag. When the shirt is fully inserted, the movement of the shirt is suflicient to overcome the friction of the bag and free it from the ends of the tongue and funnels. The upward movement carries the encased shirt over the ends of the apparatus where it may be dropped, as shown in Fig. 1, or otherwise disposed of.
Tongue I6 is convex shaped, as shown in Fig. 2, to allow the mouth of the bag to open to a predetermined shape around the ends of the funnels under the inflating air pressure. The smaller ends of the funnels are shaped to permit the article, such as the collared end of the shirt, to slide into the supported and shaped end 01- the distended bag. The bag holder is sloped downwardly at the tongue region, and thereby supports the uppermost bag in position for filling and removal. A cover 44' may be positioned above the blower and motor to prevent accidents. The switch 45 mounted in end wall [2 may be used to start and stop the blower'motor.
The bags may have their uppermost lip notched in the shape of the tongue l6 to free it, when inflating the bag while the pressure of plate 2! frictionally holds the remaining bag lip against the tongue l6 to prevent dislocation under the inflating pressure. In order to reduce the cost of notching the upper lip of the bag, the operator who inserts the shirt with the right hand may frictionally slide the upper lip free of the tongue, with the thumb of the left hand to permit inflation of the bag.
The manually freeing of the upper lip of the bag may instead be automatically accomplished with the square cam motion illustrated somewhat diagrammatically in Fig. 9. An air cylinder 50 drives the disc 5| through the pin 52 in slotted lever 53 pivoted at 54. To the rotating disc is secured a triangular cam roller 55 which fits within the square cam frame 56. A rubber tipped finger 51 extends integrally from the frame, and the motion of the cam and frame causes the finger to pass through a slot 58 in tongue 59 to free the top lip 60 of the upper bag 6! to enable the air from the blower 62 to inflate the bag to the position shown in dot-dash lines in Fig. 9.
The square cam frame is maintained in proper position during its motion by the slides 63 moving on the guide 64, which pivotally supports arms 65 to the square cam frame'56 by pins 66.
At the top rear surface 61, a pressure plate 68 controls an air valve 69, or a suitable microswitch, to operate the feed line 10 to air cylinder 50, or some other suitable equivalent mechanism such as a solenoid. Thus the weight of the article or of the hand supporting the article in position for insertion into the bag will cause the release of the upper lip of the bag to permit its inflation just prior to insertion.
In Fig. 7, reference numeral 69a designates an alternative form of micro-switch operated by arms 3'! to start the automatic cam motion, when a shirt is inserted into the funnels 36.
In Fig. 9, there is also shown a modified form of bag-holder II for supporting the bags 12 in proper position. The bag-holder is hinged at 13 to the end wall 14 and is urged upwardly by the cam 15 of pressure plate 16. The stop 11 holds the ends of the uninfiated bags position. A cam 18 secured to'shaft 19 and operated by a balance weight 80 providesthe necessary pressure 4 to the plate 16 pivoted at pin 8| to the side walls 82. The remaining parts are identical to the parts described with respect to the previous embodiments. In this embodiment, the bags are automatically inflated to facilitate rapid insertion of an article in the distended bags.
In Fig. 9, reference numeral Ha designates a spring hinged flap in bag-holder H for accommodating the extra thickness of the bags at the bottom section.
In attaining the objects of my invention, I have provided means for supporting a stack of bags in transversed arched position which I have found gives suitable rigidity to the readily collapsible bag and prevents buckling. I have discovered that the corners of the bag adjacent to its opening must be held down to prevent inflation of the succeeding bags while the top bag is being inflated. Furthermore, the tongue plate for the lips of the bag is preferably rounded at its free end to allow the mouth of the bag to assume a proper position for encircling the funnels to permit distention therein.
Additionally, I have provided spring biased funnels whereby the movement of the article through the funnels will cause the funnels to shape and frictionally support the bag in distended form and to resist dislocation until the article is properly positioned therein.
Finally, I have provided means whereby only the inflated bag will be released from the stack of bags at the completion of the fitting operation to permit ready removal from the apparatus.
I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other ways without departing from the spirit of my invention. and, therefore, I can claim broadly the right to employ all equivalent instrumentalities coming within the Scope of the appended claims, and by means of which, objects of my invention are attained and new results accomplished, as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to attain these objects and accomplish these results.
