TABBIN G-MIACHIN E.
Specification of Letters Patent. Patented July 30, 1918 Application filed August 17, 1917. Serial 110.1883.
To all whom it may concern:
Be it known that I,M1-1Lv11v H. SIonBo'rH M, a citizen of the United States, resident of Nashua, in the county of Hillsboro and State of New Hampshire, have invented certain new alid useful Improvements in Tabbing-Mac-hines, of which the following is a specification. V
This invention relates to the manufacture of paper box members having reinforced corners, and the object of said invention is to rovide a machine which will rapidly and automatically aflix reinforcements, Such as sections of strong mmed paper, to those portions. of the blan which form the corners of the boxes or box coversafter the blanks are folded.
To this end, the invention consists in' the construction and combination of parts substantially as hereinafter described and claimed. a
Of the accom anying drawing Figures 1 an tional elevation and a plan view of so much of the machine as is necessary to illustrate the invention, Fig. 1 being drawn on'line l1 of Fig. 2. Fig. 3 is an elevationof'one of the rotating disks carrying the strip aflixing mechanismon a larger scale than in Fig. 1. Fig. 4 represents a section on line 4-4 of Fig. 3 on a larger scale.
Fig. 5 represents a section on line --55 of Fi 3 on a larger scale.
Fig. 6 is a broken out plan view of a box blank which has had reinforcements applied thereto by the machine.
Similar reference characters designate similar parts .in all of the views.
Portions of the frame of the machine,
- connected by suitable braces or tie rods, are
shown at 12. By suitable feeding mechanism, not necessary to illustrate, the flat blanks are fed, one at a time and properly spaced, between upper and lower carrying belts 13, 14. Said blanks may be of any of the types to which reinforcing strips or tabs are to be aflixed. One form is shown at a in Fig. 6, the reinforcements or tabs being indicated at b. When this kind of blank is afterward folded to makethe receptacle or cover member of'the box, the sections a, y, are folded onto sections d, e, and adhesive y connected, thus forming double-thick walls. Then the portions e, f, at each end, with the 2', are respectively a sec-.
a box member a l the walls of which are of doublethickness, with concealed tabs or reinforcements at the four corners where the greatest rupturing strain is liable to occur. The presentmachine does none of this folding, but cuts off sections of tabbin material 6 from sources of supply, and a ixes four of them tothe'proper portions of each blank,
said machine having no reciprocating mem-' I bers, all parts operating by continuous motions and therefore enabling a high speed of production to be obtained.
At the delivery end, the upper belt 13 is mounted on a pulley 15 (Fig. 2) carried by shaft 16, and the lower belt 14 ismounted on a pulley 17 carried by shaft 18.
To insure accuracy of spacin of the blanks, or the timing of their trave past the devices presently described, an endless chain 19 having properly spaced pins 20, is mounted on sprockets 21, 22, carried by shafts 16 and 23 respectively. In ractice the belts 13, 14, do not grip the blank they are driven a little faster t an the chain,
. so that each blank is carried forward by the belts until its front edge abuts a in 20 after which the belts slip a little overt e sur-' face of the blank but keep it in contact with said pin, so that accurate locations or portions of the blank will be moistened and receive the tabs or reinforcements as presently described.
The operative stretch of chain 19 runs s very tightly, and a along side of and parallel with a sufficient To moisten those areas of the blanks which are to be reinforced, a shaft 24 is provided with two airs of arms 25, 26, each having an absor ent pad 27, said pads being adapted, as they rotate, to dip into a water tank 28, and then moisten the portions of each blank where the tabs b are to be applied. The hubs of the arms 25, 26
rotative adjustment provides for different are independently adjustable on shaft 24, by any well known means. Lateral adj ustment provides for different widths of blanks, and
' lengths of blanks. When properly adjustupward pressure of the pads, as they rovided with a roll 55. A spring tate, or, in other words, hold the blanks so that the pads will press with sufiicient force to insure proper moistening, suitable idle rolls 29 (Fig. 1) are employed.
The four devices for cutting off proper lengths of gummed reinforcing material 5 and affixing them to the four moistened areas of each blank in transit will now be described. As said devices are alike, a description of one will suffice. Each comprises a disk 30 carrying strip feeding and cutting mechanism as presently described. The four disks are carried by two shafts 31, having their bearings in brackets or frame uprights 32, said shafts having gears 33, both of which mesh with an intermediate gear 34 driven by a pinion 35 carried by a drive shaft 36, whereby both shafts 31 and the four disks are rotated in thesame direction as indicated in Figs. 1 and 3 by the arrows. Each bracket 32 supports a fixed stud pin 37 on which are adjustably mounted two arms 38, 39, the extreme ends of which are inclined or beveled to act as cams as hereinafter described. As shown in Fig. 2, each,cam arm 38 is set a little farther away from its associated disk 30 than its companion cam arm 39 for a reason to be described.
As best shown in Fig. 3, a coil of the reinforcin' material I) is mounted upon the hub of disk 30, said material being paper or a strip of cloth or other suitable material, having a coating of adhesive on its outer surface. The strip passes over a roll 40 mounted on a stud pin projecting from the side of the disk, then through a guide 41, between a feed roll 42 and a pressure roll 43, through a guide 44, and then between knife members 45, 46, all carried by the disk. The guides are laterally curved or arched (see Fig. 5) to cause the strip, as it issues under the fixed cutter 45, to project stifliy in a radial direction and not be deflected or bent backward by the resistance of the atmosphere, or turn sidewise, when the .disk is revolving rapidly in the direction of the arrow. 1
The feed roll 42 is actuated intermittently and alternately with the cutter 46. Said feedroll is mounted on a pin 47 (Fig. 4) carried by disk 30 and has a ratchet 48 engaged by a pawl 49 carried b a disk 50 also mounted on the pin 47 ompounded with the disk 50 is a pinion 51, engaged by a toothed segment 52 carried by a pivotally mounted sleeve 53 having an arm 54 pro- 56 tends to hold the toothed segment agamst a stop pin 57. The pressure roll 43 is carried'by a lever 58 pivoted at 59, and is held toward the feed roll by a spring 60. A suitable detent, not necessary to illustrate, is provided to prevent the feed roll from acting backwardly.
The knife or cutter 46 is guided between blocks 61 (Fig. 3) and is rigidly but removably connected to a clip 62 pivoted at 63 to an arm 64 which is pivoted at 65 to the disk 30. Said arm 64 has a side block or projection 66. A spring 67 acts to normally hold the arm and cutter in retracted position against a stop 68.
The. parts just described are all located just below, or inside of, a peripheral flange 70 of the disk 30, said flange being slotted to permit the strip material I) to pass-out, and pressure rolls 69 are mounted to bear on said flange or on the blanks passing through. Final pressure rolls may be carried by the shafts 16, 18 as indicated at 71 in Fig. 2.
It is to be understood that to provide for operation on blanks of different widths, not only are the moisteners laterally adjustable on shaft 24, but the disks 30 and the rolls 6.9 and 71 are also laterally adjustable on their shafts.
The disks, 30 are so mounted on the shafts 31 that they can be independently adjusted rotatively thereon to accommodate blanks of different lengths. For instance, if the blanks to be corner-reinforced are longer than provided for by the relative setting of the four disks as illustrated in the drawings, then the front pair of disks will be set somewhat advanced, or the rear pair will be set somewhat back, to increase the distance between the operative actions of the strip-feeding and cutting devices. The same adjustment effect can be produced by changing the rotative position of one of the gears 33 on the shaft 31 which carries it.-
In operation, each blank passing through the machine has four portions thereof moistened by pads 27, as already explained. Then each blank as it passes between disks 30 and rolls 69, has short sections of reinforcing material b, applied to the moistened areas. The feeding of the strips and the cutting off the sections is effected as follows:-The roll 55 passes freely by cam 39 but is actuated as it passes over cam 38.'
