R. W. HOAG Feb. 23, 1954 METHOD AND MACHINE FOR FILLING AND WRAPPING PACKAGES Filed Aug. 22, 1952 Patented Feb. 23, 1954 UNITED STATES OFFICE TENT METHOD AND MACHINE FOR FILLING AND WRAPPING PACKAGES Application August 22, 1952, Serial N o. 305,834 anims. `(c1. 55s- 10) This invention relates to methods and machinery for lling and wrapping articles in general, and more specifically to the manufacture of shaker dispenser packets filled with granular or powdered materials. Such a dispenser packet is described and claimed in United States Patent No. 2,499,313, issued to me February 28, 195i). This present application embodies improvements over Patent No. 2,544,020, issued to me March 6, 1951.
One object of my invention is to provide a method of nlling and wrapping webs oi packets, at high speed, by a succession of operations.
Another object of my invention is to provide a machine for lling and wrapping webs oi packets by a sequence of operations.
With said objects in view, my invention con sists in the method and machine for iilling and wrapping webs of packets substantially as hereinafter described and claimed.
Of the accompanying drawings:
Figure 1 is a plan View of the machine.
Figure 2 is a iront View of Figure 1.
Figure 3 is a plan view of a section of the wrapping material with two webs of the packets to be wrapped positioned thereon and secured thereto.
Figure 4 is a section at 13@ of Figure 3.
Figure 5 is a section at 9 5 ci Figure 3.
Figure 6 is a section at ti-- of Figure 3.
Figure 7 is a partial section at 'i-l of Figure 3.
Similar reference characters indicate similar parts or features in all 0i the views.
It will aid toward an understanding oi 'the machine, and of the method of filling and wrapping webs of packets, to describe the web of wrapping material, and the webs of packets, and thereafter explain the action oi the machine as it operates to produce filled, wrapped packets.
Referring first to Figure 3, there is illustrated a web of paper wrapper material A, which usually carries printed matter on the surface that will form the outside surface of the packet wrapper. The iirst step in my method of iilling and wrapping packets consists in longitudinally slita ting the wrapper web A at the center i3 it is advanced, thus providing two wrapper webs C and D. A web oi partly formed corrugated container elements E is positioned on the wrapper web C, and a web oi partly formed corrugated container elements F is positioned on the wrapper web D. The margin Gl of wrapper web C is adhesively treated, and the margin H of web D is adhesively treated. The said margin G of wrap per web C is folded, pressed and secured against the adjacent margin of the corrugated container elements E, and the margin H of web D is folded, pressed and secured against the adjacent margin of the container elements F. This serves to close one of the two openings oi each of the container elements. The packet webs E and F are each longitudinally cut slightly at J and K respectively to provide means :for opening the packets for pouring out the contents of the completed packets. The two web assemblies are next turned 9G degrees from a horizontal position to a vertical position to receive the commodity to be packaged in the pockets or corrugatiom: of the webs of packets. The free, upwardly extending margins ci wrapper webs C and D are next adhesively treated and then folded, pressed and secured to the adjacent margins of packet webs E and F respectively. The duplex web assemblies are then transversally severed to provide individual packet units.
Referring to Figures 1 and 2 there is schematically illustrated a machine for producing nlled packets. The several mechanisms comprising the machine are mounted on a frame l.
The wrapper web A with two corrugated webs of packets E and F are advanced horizontally to slitting knife 2 secured to shaft 3 journalled in frame i. Also secured to sha-ft 3 are two knives 1l and 5 which serve to provide dispensing cuts L and M (Fig. 3) in the crown of each pocket of the webs E and F respectively. A roller 45 journalled in frame i serves to support the web A as it is advanced. The webs are next acted upon by an adhesive applying device which serves to apply a strip of adhesive to the top, adjacent margins G and l-I of webs C and D (Fig 3) respectively. The adhesive applying device comprises` an adhesive containing receptacle l secured to frame i. .A bracket il is supported by the receptacle l'. Rollers iii and li are coated with adhesive by contact with roller 9 which rotates in liquid adhesive contained in receptacle l. The said rollers i l act in the conventional manner to deposit a film of adhesive on the margins G and l-l oi webs C and D.
As the web assemblies advance a pair of folding bars 2 and i3 secured to frame i serve to fold the adhesively treated margins G and H of webs C and D over the corresponding margins of the corrugated webs E and F. Rollers lli secured to shaft i5 journalled in frame l act to roll and press the folded, adhesively treated margins of webs C and D against the corresponding margins of the corrugated container Webs E and F;
positioned with the open ends` of thefltesioffthe corrugated pockets of web E facing upwardlyat" an angle of 90 degrees fromahorizontal. to-.ver-v tical position and is advanced.horizontally-witl the free fiat surface of web C against guide r0l1`er- 2B secured to shaft 2i and journalled in frame I.
Both web assemblies are thenadvanced-"to 'passU under a commodity filling hopper '22 securedito.I
bracket 23 mounted on -irame l. Openings 24 are provided in the bottom of the hopper through which: the product to' `be vpackaged' passes tdwn.- war-diy. and. into the corrugatedpockets:of'the container webs as they pass under the'saidopenings. Areecivin'g. .bin25is positioned underlthe openings it in the hopper'22to catch the over'-4 fiow from Athe corrugated pockets of thewebs while thellingoperation is being. performed;
Th'etwo composite webs are next advanced fromV thcillingoperation andthe top .margins N and O of I'webs'C Aand D are then folded 'at right anglesk over the flutesof container webs E and F bythe action of'folding bars `255 and 2i respectively .secured'to frame i.'
