Specification of Letters Patent.
Patented July 11, 1922.
Application filed October 15, 1920. Serial No. 417,119.
To all whom it may concern: u
Be it known that I, CHARLES C. GAMM a citizen of the United States, residin at gt. Paul, in the county of Ramsey and tate of Minnesota, have invented new and useful Improvements in Scoring and Trimming Machines, of which the following is a specification.
My invention relates to improvements in scoring and trimming machines.
My object is to provide an efficient machine for trimming and scoring pasteboard or fibre blanks in the manufacture of cartons.
More specifically it is my object to provide an improved machine which will efiiciently trim large flats of pasteboard or similar material, successively on their longitudinal and transverse sides and at the same time crease or score said flats longitudinally and trans versely.
Heretofore, it has been usual to prepare carton blanks in at least two operations by first trimming longitudinally and creasing transversely, or vice versa, in one machine and then trimming transversely and creasing longitudinally in another machine. This necessitates handling the cartons between machines, and usually requires more space for the machines, thus, increasing the cost of production.
In my improved machine the flat carton blanks are placed, one at a time, on a feed table from which they are carried longitudinally by an endless chain to gripping rolls which hold them while the primary trimming knives trim the blanks along their longer edges to a predetermined uniform size after which they pass to a second table. Here the blanks are brought against a suitable stop and carried, at right angles to their first movement in the machine, to another se ries of gripping rolls which feed them between the first scoring bars. As the blanks emerge from these scoring bars, a second series of knives trim them along their shorter edges and they are fed to a third table by a series of rolls. On the third table, like the second, the blanks are brought against a stop after which they are carried at right angles (in the opposite direction from that followed on entering the machine) to the final creasing bars. The cartons are grlpped while passing between the final creasing bars by a series of rolls and are projected onto a suitable table or conveyor.
Referring to the accompanying drawings, F igure 11s a plan View of my improved machme; 1g. 2 is a side elevation of the same; F g. 3 1s an end elevationof the same; Fig. 4 1s a side elevation of the final scoring mechamsm SlIOVYIIIg the side opposite the one shown in F 1g. 2; Fig. 5 is a section taken on the line 55 of Fig. 4; Fig. 6 is a section taken on the line 6-6 of Figure 1 and-showmg a series of the gripping rolls together w1th the second set of pusher arms; Fig. 7 is a section taken on the line 7-7 of Figure 1; F 1g. 8 1s a transverse section of the longitudinal scoring bars and the shafts and wheels on which they are mounted; and Fig. 9 is a detail elevation showing a pair of the trimmlng knives and adjacent gripping rolls.
The working parts of my machine are supported in a frame consisting of three pairs of standards 10, 11 and 12, legs 13, and horizontal beams 14. Bracing panels 15, 16 and 17 extend between the respective pairs of standards 10, 11 and 12 and are ri idly secured at their ends in said standar s.
A feed table 18 is rigidly mounted on transverse joists 19 on the horizontal beams 14, and shafts 20,and 21 are journalled at their ends in pairs of bracket bearings 22, said bearings being secured on the upper surfaces of the beams 14. An endless sprocket chain 23 is carried by sprocket gears 24 fast on the shafts 20 and 21. A sprocket gear 25 for driving the chain 23 is fixed on one end of the shaft 20. The upper run of the chain 23 moves in a suitable slot in the feed table 1.8, the top surface of said chain being flush with the surface of said table, and lugs 26 at intervals on said chain project above the feed table to engage the edges of carton blanks. An angle iron 27 bolted to the upper surface of the table 18 forms a stop against which the carton blanks are placed and a pair of channel bars 28, supporting a brush 29, are secured at their ends to the horizontal beams 14 on opposite sides of the table 18. The stifi' bristles of the brush 29 resiliently hold the carton blanks flat upon the table 18 while they are being pushed by the lugs 26 to the first gripping rolls 30. The first gripping rolls 30 and primary trimming knives 31 are carried on twoshafts 32 and 33 (shown in detail in Fig. 9) the rolls being arranged in two series one above the other. The knives 31 are circular and, being driven in opposite directions, are adapted to trim relation with the shafts 32 and 33, are
the cartons between their over-lapping edges.
The shafts 32 and 33 are journalled in the standards. 10 and the sprocket ears 34 and 35 are fast on the ends of sai shafts near the gear 25. A second series of grlppmg rolls 36 mountedjon shafts 37 and 38, which are journalled in the standards 10 in parallel PI'O- vided to grip and carry the blanks to the second table 39.
This table. 39 is similar to the feed table 18, being supported by longitudmal joists 4O vided with lugs 42, similar to the chain 23 and lugs 26, are carried by gears 43 WlllCl'l are fast on shafts 44 and 45, said shafts being journalled near their ends in bracket I bearings 46 (Fig. 3). A stop 47 is fastened to the table 39 near one end and a plurality of brushes 48 are supported by blocks 49 at- 1 one end and a bar 50 at the otherv end. The
bar 50 is suitably fastened at its ends to the standards 11 and the brushes 48 hold the cartons flat on the table 39 and prevent them from buckling as the the gripping rolls 51 ly the lugs 42.
The rolls 51 are rigid y mounted on paral-' lel shafts 52 and 53, arranged in'two series one above the other. These rolls receive the carton blanks from the table 39 and feed them to the primary creasing mechanism.
The primary and. secondary creasing mechanism are similar, details being shown in Figs. 5 and 8. The primary creasing (Fig. 8) is performed by pairs of co-acting bars 54 and 55 said bars being rigidly mounted on two series of wheels 56 and 57. The wheels56 are faston a shaft 58 and the wheels 57 on a shaft 59, said shafts being journalled in the standards 11, and the bars 54 and 55 are secured to the periphery of the wheels 56 and 57 respectively. Dies 54* and 55 extend the length of the bars 54 and 55 respectively, said bars being so positioned on the wheels 56 and 57 that in rotating they will be brought together in pairs at the adjacent sides of the wheels 56 and 57. Projections on the dies 54 fit loosely into depressions in the dies 55 and as the carton blanks C are fed between said dies the blanks will be creased as shown in Fig. 8. The transverse or secondary creasing mechanism is carried on a series of wheels 63 said 'wheels being arranged in pairs and rigidly secured to the parallel shafts 64 and 65. The transverse creasing bars 66' and 67 are similar to, but shorter than the creasing bars 54 and 55 respectively described above and dies 66 and 67, mounted in said bars, are similar to the dies 54 and 55 respectively. Any desired number of creases may be made in the blanks by placinga corresponding number of pairs of bars on the periphery of the wheels 56, 57 and 63. These bars and the bars 66 and are pushed toward erium of the wheels 56, 57 and 63 by means 1 of blocks 60, which are secured b to the bars 54, 55, 66 and 67 an by bolts bolts 61 62 to the inner peripher of flanges 56, 57 I and 63 of the'wheels 5 57 and 63 respectlvely. The bolts 62 are in thenature of set screws and are adapted to impinge 4 against the inner periphery of the flanges 56, 57 and 63"- to ,secure the bars 54, 55,
66 and 67 at the desired points on the wheels on the horizontal beams 14. Chams 41 pro 56, 57 and 63.
the transverse trimming knives 68. These I knives are'similar to the primary trimming knives 31 and are mounted on two parallel shafts 69 and 70. While being trimmed the cartons are gripped b a series of rolls 71 mounted on the sha ts 69 and 70. The cartons are then gripped by another series of rolls 72 mounted on two shafts 72 and 72 and fed onto a third table 73.
The table 73 is similar to the table 39 being supported by a plurality of joists 74 on the horizontal beams 14. An angle iron 75 bolted to the upper surface of the table 73 forms a stop for the cartons opposite v the rolls 72 and a pair of endless chains 76 mounted on sprocket gears 77 and carrying a series of push bars 78 are adapted to carrythe cartons longitudinally in-the opposite direction from which they were carried by the chain. 23 on the table 18. A pair of brushes 79 are mounted above the table '73 on angle irons 80 extendin across the ends of said table, which ange irons are supported by blocks 81 near their ends. The sprocket gears 77 'are rigidly mounted on shafts 82 and 83, said shafts being journalled in bracket bearings, similar to the bearings 22, on the u .per surface of the horizontal beams 14. he push bars 78 are adapted to carry the cartons toward and feed them between a series of gripping rolls 84. The rolls 84 are rigidly mounted on shafts 85 and 86 (Fig. 4) and are provided to grip the cartons while feeding them to the transverse creasing bars66 and 67 described above. After being creased transversely the cartons are fed between a final series of gripping rolls 87 mounted on parallel shafts 88 and 89. These rolls deposit the trimmed and creased cartons on a suitable table or a conveyor placed at the a gear 94 on a shaft 95 parallel to the shaft 91. A bevel gear 96 rigidly mounted on the shaft 95 meshes with another bevel gear 97 fast on one end of the shaft 53, and a pinion gear 98 (Fig. 3) on the other end of said shaft meshes with a gear 99 on the shaft 52, and an idler (gear 100 interposed between the gear 98 an a gear 101 on the end of the shaft 59. The gear 101 meshes with a gear 102 on the shaft 58 and another idler gear'103 and the latter in turn meshes with a gear 104 for driving the shaft 70. The gear 104 meshes with a gear 105 on a shaft 69. v
A sprocket chain 106 is provided to transmit power from the shaft 53 to the shaft 45 for driving the chains 41 on the table 39. For this purpose sprocket gears 107 and 108, rigidly mounted on the ends of the shaft 53 and 45 respectively, are provlded to carry the chain 106.
The rolls 72 on the shafts 72 and 72 are driven by chains 109 and 110, the chain 109 being adapted to engage gears 111 and 112 on the shafts 72 and 69 respectively, and the chain 110 being adapted to engage gears 113 and 114 on the shafts 72 and respectively.
Power for driving the transverse creasing mechanism is transmitted from the shaft 95 to the shaft 86 through gears 115 and 116 (Figures 1 and 4). A gear 117 on the opposite end of the shaft 86 meshes w1th a gear 118 for driving the shaft 85 and an idler gear 119. The idler gear 119 meshes with a large gear 120 fast on'the shaft 65 which in turn meshes with and drives a gear 121 on the shaft 64 and a second idler gear 122. The latter gear drives a gear 123 on the shaft 89 which in turn drives a gear 124 on the shaft 88.
Power for driving the primary trimming knives and gripping rolls is transmitted from the shaft 95 to the shaft 32 by means of gears 125 and 126. A gear 127, on the opposite end of the shaft 32 engages a gear 128 on the shaft 32 to drive these shafts in opposite directions and a sprocket chain 129 engages sprocket gears 130 and 131 on the shafts 32 and 37 to drive said shafts in the same direction. The chain 132 similar to the chain 129 causes a gear 133 on the shaft 38 to revolve in the same direction as the gear 35 on the shaft 33 and a sprocket gear 134, mounted on the shaft 33 between the gear 35 and the gear 128, engages the chain 135 for driving the gear 25 on the end of the shaft 20.
To insure the accurate spacing of the carton blanks on the tables 39 and 73, I provide mechanism for pushing said blanks, as they are released by the rolls 36 and 72, against the stops 47 and respectively. For this purpose a pair of pusher arms 136 (Fig. 2) are tiltably mounted between the imparts reciprocating thereto.
the lower end of sald spring being fastened to the panel 15. A cord 140 also connected to the bar 138 passes beneath the table 39, around pulleys 141 and 142 and is fastened at its other end to the end of an arm 143 (Flg. 3). The opposite end of the arm 143 is pivotally mounted on the face of one of the standards 11 by means of a pin 144, and a cam 145, rigidly mounted on the inner hub of the gear 102, is arranged to rotate beneath the. arm 143 and to tilt said arm about the pin 144. Tilting the arm 143 motionto the cord 140 and tilts the pusher arms 136 against the action of the spring 139. A second spring 146, fastened at its lower end to the arm 143 and at its upper end to one of the rods 155, hereinafter described, tends to hold the arm 143 up and to oppose the action of the spring 139.
The second series of pusher arms 147, shown in detail in Figs. 6 and 7 are rigidly mounted on a shaft 148, said shaft being journalled in'the standards 11. One end of the shaft 148 projects through one standard 11 and has a rocker arm 149 rigidly secured nected at one end to said rocker arm and at its other end to the hub of the gear 101. The connection between the rod 150 and arm 149 is adjustable vertically, the rod 150 being pivotally connected to a block 151 which is slidable in a recess 152 in the arm 149 and adapted to be fastened at any point within said slot by means of a bolt 153 which passes through a slot 154 in said rocker arm. A brace 147 extending between the three arms 147 and rigidly attached thereto, is provided to strengt en said arms. As the gear 101 rotates, the connection between the rod 150 and said gear being off-set from the center of the shaft 59, the arm 149 together with the pusher arms 147 are given tilting motion which causes the carton blanks to be pushed against the stop 75, as soon as they are released from the rolls 72.
The pressure between the various pairs of gripping rolls 30, 36, 51, 71, 72, 84 and 87 and the longitudinal and transverse scoring bars is adjustable by means of a series of rods 155. These rods are squared to receive a wrench at one end, are revoluble in ears 156 and have worms 157 rigidly mounted thereon. The worms 157 are adapted to rotate Worm wheels 158 which are fast on substantially vertical shafts 159 (Figs. 4
V This rocker arm is given a tiltingmotion by a rod 150 which is pivotally conof the standards 10, 11 and 12. The lower portions of the shafts 159 are threaded and adapted to engage a correspond ng taped hole 162 in bearing blocks 163, which blocks contain bearings for the several upper shafts of the pairs of gripping rolls and scoring mechanism and are slidable substantially vertically in the standards 10, 11 and 12. Thus by turning the rods 155, carrying the worms 157, the wheels 158, together with the shaft 159, will be rotated and the blocks- 163 carrying the upper shafts may be raised or lowered as desired.
