11]., a corporation of Delaware Application October 23, 1956, Serial No. 617,829 7 Claims. (Cl. 53-476) This invention relates to machines for conveying and packaging articles of manufacture and particularly to such machines wherein the articles are to be enclosed by a peripheral band of fibrous material which is placed within a conveyer bucket, thereby facilitating the subsequent insertion of the articles into a carton.
A conveyer may comprise a plurality of especially adapted holders dimensioned to contain articles in a particular configuration. In industry, these holders are known as buckets and for the purposes of this specification, the term bucket will be used accordingly. Ordinarily, a bucket will have a flat supporting structure and two opposed spaced walls at the leading and trailing sides thereof. For packaging articles, such as paper envelopes containing quantities of powdered or granular material, it may be desirable to include within each bucket a peripheral band of cardboard or other fibrous material to contain the envelopes and to permit the transfer of the envelopes from the bucket into a cardboard carton as a group or unit. The peripheral band which is inserted into the cardboard carton with the articles will then constitute a reinforcing structure to strengthen the carton.
This invention consists generally of a new and improved mechanical arrangement for inserting a peripheral band of fibrous material into each of the successive buckets moving along a conveyer.
An object of this invention is to provide an improved arrangement whereby the bands are stacked flat one against the other in a magazine, and whereby the bands may be removed singly from one end of the stack in the magazine, expanded from the flattened state into a substantially rectilinear configuration and inserted into a bucket moving on the conveyer.
A further object of this invention is to provide means for expanding each band partially as the band is carried by a transfer member or arm from a first rest station to a second rest station and subsequently for completely expanding the band after it has been inserted into the conveyer bucket; more specifically, it is an object to provide apparatus wherein the partially expanded band, having a reduced dimension longitudinally of the conveyer, opposite ends thereof extending beyond the confines of the bucket in a direction transverse to the conveyer, and a means such as rails positioned adjacent to the conveyer to thence impinge upon the opposite corners of the band compressing the corners together and forcing the band to assume a rectilinear configuration completely enclosing the space within the bucket.
Another object of this invention is to provide a simple mechanical arrangement for stripping the bands singly from the magazine and subsequently for pushing the partially expanded band into a conveyer bucket; and more particularly, a stripper member and a pusher member, both of which require similar reciprocatory motion for their respective operations, may be mounted on a single reciprocating carriage; thus affording a simplicity of design and an economy of manufacture.
A more complete understanding of the present invention, its mode of operation, and its advantages, may be gathered from further reading of this specification, together with an inspection of the accompanying drawings in which:
Fig. 1 is a perspective view of a portion of the packaging machine employing the teachings of this invention and particularly showing a part of the magazine for holding flattened bands, the transfer and expansion mechanism, and a part of the conveyer for receiving the ex panded bands;
Fig. 2 is a perspective view of a single peripheral band of cardboard as it is expanded into a rectilinear configuration within a bucket of the conveyer;
Fig. 3 is a vertical section showing the magazine and transfer elements shown generally in Fig. 1;
Figs. 4 and 5 are similar enlarged vertical sections of a portion of the structure also shown in Fig. 3; Figs. 3, 4 and 5 show the transfer mechanism in different positions to illustrate the operating sequence as the elements move and carry the bands from one station to another;
Fig. 6 is a vertical section along the line 6-6 of Fig. 3;
Fig. 7 is an enlarged section along the line 7--7 of Fig. 6; and
Fig. 8 is a vertical section along the line 8-8 of Fig. 6, which line being the same as the line 6-6 but looking in the opposite direction therefrom.
In the operation of the machine of this invention, the peripheral bands 1 are folded flat and stacked one above the other in a magazine 2 which may include a pair of spaced apart end rails or guides 3 having inwardly turned flanges 4 such that the ends of the bands 1 are confined therein. The bands will move downwardly in the magazine under the influence of gravity and will rest at the bottom thereof upon a pair of spaced apart stripper members 5', Figs. 4 and 5. The stripper member reciprocates with horizontal motion transverse of the magazine -2 and contains a stepped-down forward end 6 having a recessed or depressed horizontal surface with an abutting edge 7 extending vertically a distance less than the thickness of each band. Thus, as the stripper member 5 moves to an extreme rearward position, as shown in Fig. 3, the bottom or lowermost band will drop upon the stepped forward end 6. As the stripper member 5 moves forwardly across the bottom of the magazine 2, the vertical edge 7 thereof engages and moves the lowermost band 1 horizontally and forwardly from the magazine 2 through the position shown byFig. 4 and ultimately to a rest station A, shown in Fig. 5.
A transfer member 8 is mounted rigidly to a shoe 9 positioned to slide vertically in a track 10 and contains a suction cup 11 at the upper extremity thereof, Fig. 3. The vertical transfer member 8 moves upwardly to an extreme position wherein the suction cup 11 engages a side of the flattened band 1, Figs. 3 and 6, whereupon a reduced air pressure or vacuum is applied tothe suction cup 11 to cause the band 1 to adhere thereto. The transfer member 8 thence moves downwardly pulling the band 1 therewith to a second rest station B, Fig. 4. A guide member 12 extending downwardly from the rest station A, Fig. 6, contains a diagonal surface 13 with a track 14 extending therealong. As the band 1 is drawn clown wardly by the suction cup 11, the diagonal surface 13 impinges thereupon such that the parts of the rectangular band are separated or partially expanded as the band moves from station A to station B.
From station B, a pusher member 15, having a broad flat face 16 thereon, engages the partially expanded band 1 and pushes the band from the station B into a bucket 17 on a moving conveyer chain 18, Fig. 5. The partially expanded band 1, Fig. 8, is thence moved upwardly around the end of a sprocket 19 supporting the conveyer chain 18 utimately to assume a horizontal position thereon, whereupon the bucket 17 and the band 1 therein move linearly away from the sprocket 19 for a subsequent packaging operation (not shown). As the bucket 17 moves upwardly around the endof, the. sprocket, a. stationary rail. 20 impinges against an extending corner of the band 1, Fig. 8, and converges with the band into close spaced relation with the-bucket at 21. The band lissthus forced-into a rectangular; configuration; as.shown;in Fig.v.2,jfullyoccupying'thespaceofuthe buckeb Thus, ,theperipheralzband 1, in combination; with the bucket, forms a" closed pocket into which the manufactured articles may be :inserted: and heldas the-bucket Ltravelsfor further packaging :operations tigsubsequently may be insertedinto. a; cardboard carton:

The. station A;, Fig. 5, is specifically definedby a springurged guide member. 31whichcooperates with. a rounded end portion 32 fixed to the'bottom or lowermost part of the magazine 2.}. As the stripper-.memberSmoves forwardlyafrom; the magazineZ, theguide member .31 urged downwardlyby springs 33, secures the bandl against the recessed part 6 of the stripper member'S. When. the stripper member moves to an extreme forward position, Fig. 5,.a recessed part 34 of the guidemember 31 receives and retains the band 1 therein. The guide member: 31 is mountedxon a pair ofstuds 35 which'may'move upwardly against the urging of thesprings 33 and are-held by 21 stationary bracket 36.
As shown in Fig. 6, one end of the band 1 positioned in station,;A may be supported .uponia spring-urged ledge 37 pivotally mountedat-38 on a bracket 39 and held by a spring .40; When thetransfer member 8 moves downwardly to pull the band 1 from thestation A, the ledge part 37 may be depressed. somewhat, as shown by thedashed lines in Fig..6, and the. corner of the band 1 is retainedby a recessed step 41 therein. As the-band is drawndownwardly by the". transfer member or suction means 8, one end impinged. against the inclined surface 13 will gradually expand therealong. The surface 13 terminates with an ofiset or recessed part at 42. The partially expanded band will bepulled downwardly until the corner thereof passes the shoulder or recess 42.and is thereby prevented from resiliently recoiling toward its initial position. After the corner is retained by the ledge or recess 42,ythe vacuum may be cut ofi from the suction cup 11 and the transfer member 8 will continue down somewhat after becoming disengaged from the band 1, ultimately to'a positionshown in Figs. 4 and 5. Thus, the. transfer member 8 remains clear and will not transfer with the'pforward movement of the pusher member 15.
wholly expanded, the pusher member'lS may thus readily insert-it intoa bucket '17 at a time just subsequent to.the
position shown inFig. 4. Becausethe band 1 is not fully expanded its dimension longitudinally ofthe conveyeris less than the dimension of the bucket 17, thus permitting positioned-in closespacedrelation to the conveyer 18 and the buckets 17 there'o'n.- should anyband'l be improper lyplaced within the respective bucket l7; it will engage Such movement may'cause operation-of a microswitcn w which the arm 45' causing pivotal movement thereof.
