FLANGE HOLD-IN DEVICE FOR WRAPPING MACHINES y Filed Dec. 16, 1943 9 ffw Patented ug. 22, 1944 FLNGE HOLD-IN DEVICE FOR WRAPPING MACHINES Oscar Sandberg, Defiance, Ohio, assigner to Lynch Manufacturing Corporation, Defiance, Ohio, a corporation of Ohio Application December 16, 1943, Serial No. 514,471
Y Claims.
My present invention relates to a hold-in device for the flange of an article receiving boat in a wrapping machine which wraps a Wrapper around the boat and article.
One object of the invention is to provider a hold-in device of simple construction involving a minimum of parts for its operation in timed relation to other mechanism of the Wrapping machine.
Another object is to provide a hold-in device which is movable to two different positions; one wherein it permits boats with articles therein to pass freely beneath it, and another where it swings in back of the boat for holding a flange of the boat from assuming an improper position and instead, guiding it into a folding way.
A further object is to provide a stop plate cooperating therewith so that both flanges of a channel shaped article holdingr boat are properly guided into the folding way without danger of springing outwardly before entering the way and jamming the machine, or at least spoiling the package.
With these and other objects in view, the invention comprises the combination of elements and the arrangement of parts which are so combined with each other as to cooperate in the performance of the functions and accomplishment of the results herein contemplated. The inventioncomprises in one of its adaptations the species or preferred form illustrated in the accompanying drawing, wherein- Figure 1 is a side elevation of a portion of a wrapping machine, such as shown in my Patent No. 2,283,097, with my present flange hold-in device added thereto.
Figur-e -2 is an enlarged View of the hold-in element shown in section and showing the normal position thereof while a pocket of a conveyor passes beneath it, such pocket being illustrated with a channel-shaped article holding boat therein and an article such as a candy bar in the boat.
Figure 3 is a similar view showing the pocket further advanced and the hold-in element being swung from the posiiton in Figure 2 to another position, it being intermediate the two positions.
Figure 4 is a similar View showing the hold-in element in said another position when the pocket is in position for elevation of the boat and article into a folding Way; and
Figure 5 is a sectional View on the line 5 5 of Figure 4.
On the accompanying drawing I have used the reference character F to indicate a wrapping ma-. chine frame, and T a wrapper supporting table. Above the table T a folding way F is mounted, as shown in my prior patent', and spaced above the table so that a wrapper can be positioned between thev table `and the folding way. The Wrapper is not shown in the drawing, however.
The Wrapping machine includes a pocket conveyor, Ill-l2, H10-being the chain thereof and I2 the pocketsY thereof. AThe pocket conveyor is driven by a chain i3 from a Geneva movement including a starwheel I4 and a cooperating disc l5, arm I6, and rollerll.- This type of drive, upon rotation4 0fa shaft t3 on which the elements I5, i6 and Hare mounted, results in intermittent movement of the star wheel I4 and consequently the pocket conveyor til-l2. The stopped position of eachA pocket in relation to a folding Way FW is shownin Figure 1.
The pockets l2 are adapted to receive channel shaped cardboard boats i9, such as disclosed in my co-pending application, Serial No. 461,709, filed October l2, 1942, and the boats in turn' receive articles 20, suchas candy bars or pieces of candy. The boats and candy `are then adapted to be wrapped, in a wrapper of paper, or the like, by elevation of the boats by a vertically movable ram 2| (see Figure 1) which engages them with the bottom of a wrapper on the table T (not shown) and moves them up through the folding WayFW for draping the wrapper about the boat and article, they downhanging ends then being folded in under the article, as shown in my former patent. Y
The boats i9 have a tendency' to spring open although they are held by the sides of the pockets I2. When the ram 2| elevates a boat out of the pocket there is danger of the flanges of the boat spreading to such an extent that they engage the edges of an opening 22 in the table T or the lower end of the folding Way FW and thus either jamming the machine or spoiling the package. To take care of this, the front flange of `the boat is guided by a stop plate 23 depending from the table T and having therein-a notch 24. The notch 24 permits passage of the c onveyor pocket but portions 25 of the stop plate'beyond the ends of the notch 24 engage the front flange of the boat as shown in Figure 5 to cause the ange to cooperate with the main bodyportion of the plate 23 which properly guides it up through the opening 22 and into the folding way.
A stationary plate of this character cannot be provided for the rear flange of the boat. However, I do provide a similar plate 232t having a notch 2lia and end portions 25a, which plate is movably mounted by attachment thereof to a rock shaft 26. The rock shaft 26 is journaled in suitable bearings 2l depending from the table T and is operated to two different positions, as shown in Figures 2 and 4, by an arm 28, a link 29, a bell crank 30 pivoted at 3l on the frame F, and a cam disc 33. The disc 33 has a cam groove 34 in which a roller 35 of the bell crank 30 travels for timing the movements of the hold-in element 23a with relation to the pocket conveyor lU-I 2.
Normally, the hold-in element 23*al assumes the position of Figure 2, but when a pocket l 2 reaches a position of alignment with the folding way FW and stops in that position, the flange 23a is in the position of Figure 4 and remains there until the ram 2l has raised and then starts to lower. The element 23a is then moved back to the position of Figure 2 so that the next boat and article coming to wrapping position does not strike it, but instead passes under it, as shown in Figure 2.
My hold-in device is substantially simple in construction and effectively retains the boat |9- against any spreading to an inoperative position. Its flanges are guided into the folding way FW without buckling or being otherwise damaged.
Some changes may be made in the construction and arrangement of the parts of my flange holdin device for wrapping machines without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included Within their scope without sacrificing any of the advantages thereof.
