CORRUGATED-BOARD-MAKING MACHINE.

Application filed June 4,

enable others-skilled in the art to which it v appertains to make and use the same.

The present invention relates to machines for making corrugated or cellular board from several sheets or plies of paper or other material, and aims .to provide a machine of that character utilizing novel and improved means for pressing and drying the board after the sheets are pasted together.

The invention has for its object the provision of such a machine in which the board, after the sheets are brought together and pasted, is cut into lengths and the severed pieces. or lengths shifted laterally or otherwise away from the path of movement of the board, for the pressing and drying op eration, in order that the pressing and drying of the severed pieces of board can be accomplished independent of the forward feeding of the board from the corrugating and pasting or assembling means.

The usual practice is to subject the board, while moving, to pressure and heat, for pressing the sheets together and drying the paste, whereas with the present arrangement, the board is severed, and the severed piece or length is shifted to one side or, laterally for the pressing and drying operation independent of the forward movement of the sheets in making the board, and also enabling the, severed sheets or lengths of board to be subjected to pressure and heat while stationary.

A further object is to provide a machine of the character indicated having novel means for cutting the board, shifting same when out, and subjecting the severed piece when shifted to pressure and heat, with op- Specification of Letters Patent.

The machine comprises a suitable frame 1, and means for corrugating or similarly forming one of the sheets and then bring ing the sheets together and pasting them one on the other to produce the corrugated or cellular board. As shown, a corrugatingroller 2 is mounted in the frame, and a similar roller' 3 is also mounted in the frame below the roller 2 with the corrugated peripheries of the rollers meshing.v

peripheral surface to press down on the roller 2, and the axle of the roller 6 is carried by bearings 7 slidable vertically in the slots of the frame and adjusted by screws 8 to press the roller 6 down on the roller 2 with the desired tension. Another pressure roller 9 is located above the roller 6 and is the sheet passes tangentially to the bottom carried by bearings 10 slidable in the sides of the frame and adjusted by screws 11.

As illustrated, the cellular or corrugated board is made up of three sheets of cardboard, paper, or the like, and the three rolls of papers are supported in the frame. One roll 12 supplies the intermediate sheet 13 which is corrugated, and said roll is preferably supported underneath the roller 3. The sheet 13 passes upwardly from the roll 12 between the corrugating rollers 2 and 3, and then passes upwardly along the roller 3 and thence between the rollers 2 and 6. The corrugated sheet 13 then passes from the roller 2 upwardly along and over the roller 6 under the roller 9 to pass forwardly past the cutting device. A second roll 14'of paper is supported by the frame near the roll 12, and the sheet 15 passes upwardly from the roll 14 over a guide roller 16, from which portion of the roller 6, and thence upwardly around said roller and forwardly from the top thereof. The sheet 15 is thus fed around the roller 6 under or in back of the corrugated sheet 13, thus associating said sheets by passing the sheet 15 partially around the plaln roller around which the corrugated sheet passes from the corrugating roller 2. A third roll 17 of paper is supported by the frame near the roll 12 and the sheet 18 passes upwardly from said roll over a guide roller 19 and thence under the roller-9 onto the corrugated sheet 13 where it passes over the roller 6. The roller 9 thus presses the sheet 18 against that side of the corrugated sheet opposite to the sheet 15. Feed rollers 20 are preferably employed between the roller 19 and rollers 6 and 9 to feed the sheet 18.

The axles or rods 21 which support the

rolls

12, 14 and 17 are seated in brackets 22 which are slidable vertically along upright portions of the frame, and said brackets are adjusted by screws 23 or the like, in order that the rolls can be adjusted up and down at their opposite ends, so that the sheets will pass smoothly from the rolls to the respective rollers without tearing or wrinkling. This is especially useful when the rolls of paper are irregular or tapered.

There are two paste applying means for the opposite sides of the corrugated sheets, and each of such means includes atransverse paste applying roller 24 to bear against one side of the corrugated sheet and apply the paste to the bends of the sheet, said rollers 24 bearing on paste rollers 25 which rotate within paste pots 26, so that rollers 25 elevate the paste and apply a film thereof to the rollers 24. The paste applying roller 24 of one device is located at one side of the corrugating roller 2 to bear against the corrugated sheet, where said sheet passes around said roller. while the other roller 24 is 10- cated at the opposite side to apply paste to the opposite side of the corrugated sheet where it passes around the roller 6. The paste is thus applied to the opposite sides of the sheet 13 before it comes into contact with the

sheets

15 and 18. Then, when the three sheets pass under the roller 9 they will be pressed together.

The rollers 24 are mounted on shafts or axles 28 which are carried by bearings 29 slidable in slots 30 in the frame to adjust said rollers to and from the corrugated sheet, by means of screws 31.

A pair of feed rollers 33 is arranged immediately forwardly of the rollers 6 and 9 for feeding the board forwardly, assisted by a pair of rollers 34 and upper and lower sets of feed belts 35 mounted on transverse shafts 36. The board in passing from the rollers 6 and 9 between the rollers and 34, and between the belts 35 will be fed forwardly on the table 32 of the frame.

A cutting device is employed for cutting the board when a predetermined length thereof has been moved past the cutter on the table 32. This device includes a transverse cutter 37 carried by a bar 38 having its ends slidably mounted in the frame, and said bar is moved upwardly and downwardly by means of links 39 connected thereto and having straps or bands 40 mounted on eccentrics 41 secured on a transverse rock shaft 42 journaled in the frame above the table. \Vhen the shaft 42 is rocked, the action of the eccentrics 41 will raise and lower the cutter or knife 37, thereby cutting the board and retracting the cutter.

The severed piece or length of board is shifted laterally for the pressing and drying operation, and, for this purpose, a table 43 is disposed at one side of the table 32, being a lateral extension of the table 32, and a flat presser plate or head 46 is mounted for vertical movement above the pressing table 43. The table 43 and plate 46, as well as the table 32, are hollow, as shown in Fig. 8, for receiving steam or. other heating fluid for heating -such members and drying the board when fed on the table 32 and then shifted laterally on the table 43 under the plate 46. The steam is supplied to the table 43 and plate 46 by means of piping 44, and the rollers 34 are also preferably hollow and supplied with steam to heat and partially dry the board where it passes between said rollers, and the steam or water of condens:

tion is discharged throu h the piping 45.

The presser plate 46 1S slidable vertically in the frame above the table 43, and is moved vertically by means of links 47 connected to said plate and having straps or bands 48 embracing eccentrics 49 secured on transverse shafts 50 above the tables 32 and 43. Said shafts are mounted in vertically ing adjustable bearings 51, adjusted by means of screws 52, for regulating the pressure of the late 46 on the board, and accommodatards of various thicknesses.

. A set of longitudinal rollers 53 is disposed between the tables 32 and 43, and are carried by vertically adjustable bearings 54, adjusted by means of screws 55, or the like, and the severed piece of board passes from the table 32 between the rollers 53, which feed the board laterally onto the table 43.

The rollers 53 are also preferably hollow and supplied with steam from the piping 44 to heat and dry the board as it passes between said rollers. The rollers ,53 are operatively connected, as at 56, to a longitudinal drive shaft 57 ,-so as to rotate continuously during the rotation of said drive shaft.

Associatedwith the table 43 is a device for creasing or scoring and cutting the board as it is delivered from said table. Such device comprises a pair of parallel vertically spaced shafts 57 mounted in the frame at that edge of the table 43 opposite to the table '32, and said shafts are operatively connected, as at'59, with the rollers 53 to be rotated continuously therewith. Mounted on the shafts '57, are ordinary creasing or scoring rollers or wheels 60, and cuttin disks or cutters 61, which can be arrange in various positions, for cutting the board into smaller pieces, as desired, and scoring or creasing the pieces at the desired points thereof, as the board leaves the table 43.

, The shifter for shifting the severed lengths or piece of board from the table 32 laterally between the rollers 53, comprises a longitudinal shifter bar 62 slidable on the table 32 at that side thereof opposite to the table 43,'and said bar 62 is connected by links 63 with an operating lever .64.

Coming to the operating mechanism. of the machine, the gearing 65 of the

rollers

34, 33, 9, 20, 6, and so on, and belts 35, is connected by a clutch 66 with gearing 67 operated by .the drive shaft 57, whereby said clutch in being opened will stop that portion of the machine which brings the sheets to gether and feeds them forwardly past the cutter 37 on the table 32. The clutch 66, shifter bar 62, cutter 37 and presser plate 46 are operated in timed relation by means of a cam 68 mounted on a transverse shaft 69 having a bevel gear wheel 70 meshing with a onto the table 32, and this device includes a rod slidable in guides 76 of the frame and between the

friction wheels

77 and 78,

the wheel 77 being operated by'the gearing rod being graduated so that the tripping,

finger can be adjusted to operate the mechanism when the desired length of board has been fed past the cutter 37. This finger 81 contacts with a tripper arm 82 secured on the shaft 74 when the rod has been advanced the predetermined-distance, thereby swinging the

arms

82 and 73. The arm 82 has a stop 83 to limit the movement when the clutch 72 is opened, and a spring 84, (see Fig. 5) between the arm 82 and the frame will result in the sharp movement of the arm 82 and clutch 72 to either position when moved past dead center or intermediate position. Thus, the spring 84 will hold the clutch in either open or closed position, and when the

arms

82 and 73 are swung to reverse the clutch, the spring 84 is brought under tension as it moves to intermediate or dead center position, and will then cause the clutch to open or close with a sharp movement. finger 81 contacts with and swings the Therefore, when the tripping tripper arm 82, the spring 84 will come into the return movement of said rod, and said cord passes over a pulley 87 and has a weight 88 connected thereto. Thus, when the lever 79 is swung to remove the wheel 78 from the wheel 77, the rod 75 is returned by the weight 88, although a spring can be used as an equivalent.

The rotation of the cam 68 operates

levers

89, 90 and 91 in succession, said levers having rollers or other means engaging within a cam roove 92 of the cam. A link.93 connects t e lever89 with a lever 94 that operates the clutch 66, and said lever 89 also operates the presser plate 46. Thus, a link 95 connects the lever 89 with the lever 96 that is connected by a link 97 with an arm 98 secured to one of the rock shafts 50. Said shafts 50 have arms 99 connected by a link 100, whereby both of them oscillate in unison, so that the plate 46 will move upwardly and downwardly in a horizontal position. The link 97 has a turn buckle 97' for adjustment. The lever 89 is normally held in one position by the cam when in idle position or at rest, thereby holding the clutch 66 closed and the presser plate 46 down. The corrugated board is made and fed forwardly on the table 32, and during such making and feeding of the board, the piece or length previously severed is being pressed on the table 43 under the plate 46. The lever 90 is connected by a link 101 with an arm 102 of the lever 79, to move the wheel 78 to releasing position, when the cam 68 has turned a certain distance and said lever 90 is also connected by a link 103 with an arm 104 on the cutter shaft 42, to operate the cutter after the lever 89 has been swung to open clutch 66. The lever 91 operates the shifter, being connected by a link 105 with a lever 106, which is in turn connected by a link 107 with the shifter lever 64,'the link107 being preferably adjustably connected with the lever 64, whereby to enable the shifter bar 62 to be positioned at the desired lateral position on the table 32, according to the width of board being made.

In order to open the clutch 72 and stop the cam 68, when said cam has completed one revolution, a finger 108 is pivoted to the'gear wheel to extend at an angle therefrom so as to contact with the arm 73 and swing said arm to open the clutch 72. Said finger 108 is pivoted to swing away from the arm 73, and is yieldingly retained in position by the spring 109, which enables said finger to yield and pass the arm 73.

The operation of the machine is as follows: The tripping finger 81 is adjusted on the rod 75 to the graduation according to the length of board to be-cut oil on the table 32, and when the machine is in operation for making the board and feeding same, the clutch 66 being closed, the rotation of the wheel 77 will advance the rod 75 proportionally with the board. Then, when the desired length of board has passed the cutter, the tripping finger 81 in contacting with the tripper arm 82, will swing said arm assisted by the spring '84, thereby closing the clutch 72, and connecting the cam 68 with the drive shaft 57. The first movement of the cam 68 will swing the lever 89, to open the clutch 66, thereby stopping the making and feeding of the board. The movement of the lever 89 will alsorock the shafts 50, whereby to raise the presser plate 46, and the clutch 66 is held open and the plate 46 held in raised position during the completion of one revolution of the cam 68. After the lever 89 is moved, as above stated, to open the clutch 66 and raise the presser plate 46, the

levers

90 and 91 are oscillated in succession. The oscillation of the lever 90 will reciprocate the cutter 37 to cut the board, thereby providing a length or piece of desired length on the table 32, and said lever 90 will also oscillate the lever 79, thereby releasing the rod 75 for a moment, in order that the weight 88 will return said rod to initial position. The oscillation of the lever 91 will reciprocate the shifter bar 62, thereby shoving the severed piece of board laterally on the table 32 between the rollers 53, which will feed the piece or length of board onto the table 43 under the plate 46. The board in passing the rollers 34, moving on the table 32 and passing between the rollers 53 will be heated so as to dry the paste, and the board is subjected to final pressure and heat on the table 43. When the cam 68 has completed one revolution, the lever 89 is returned, thereby again closing the clutch 66, and moving the presser plate 46 downwardly, and the finger 108 in contacting with the arm 73 will open the clutch 72 thereby stopping the cam 68 in this position, as seen in Fig. 4. The making and feeding of the board is therefore again taken up, and the severed piece or length of board whichhas been moved on the table 43, is subjected to pressure and heat, the plate 46 in being moved downwardly pressing said piece or length 'of board between the table 43 and plate 46, thereby pressing the sheets firmly together and drying them. The piece or length of board which was previously on the table 43 is ejected therefrom by the lateral movement of the last severed piece between the rollers 53 and the piece of board which is ejected from under the plate 46, passes through the device for scoring or creasing and cutting the board, including the rollers of whieels 60 ,and cutters 61. Thus, as the pieces of board are delivered from the pressing and drying means, they are scored or creased and cut, and can be caught on a suitable table or other receiver located at the side of the table .43 beyond the scoring or creasing and cutting device.

A modified construction is shown in Figs. 9 and 10. The machine is generally like that, above described, with modified means for shifting the severedlengths or piece of board laterally to the rollers 53, similar means for shifting the sheet from the table 43 and a different arrangement of the scoring or-creasing and cutting device. An adjustable slide 120 is disposed within an openslidable in grooves 122 in said table, in order that said slide can be adjusted transversely, such as by means of an adjusting screw 123 Paiallel longitudinal shafts 124 are carried by the slide 120 and sprocket wheels 125 are ing 121 in the table 32-and has its ends adjustably secured on said shafts and have endless sprocket chains 126 trained around same. A longitudinal shaft 127 is journaled in the table 32 and the ends of the slide 120 have slots 128for the passage .of the'shaft 127, and permitting said slide to be adjusted. Sprocket wheels 129 are secured onthe shaft 127 by means of set screws 130, or the like, and the sprocket wheels 125 are similarly secured, whereby the sprocket wheels can be shifted longitudinally to different 0- sitions, according to the length of board that is severed. The sprocket wheels 129 engage thechain 126 for actuating them, and shafts 124 are located at opposite sides of the shaft 127 and can be shifted transversely wtih the slide 120. The chains 126 have In s 131 adapted to move laterally at the sur ace of the table 32' for shifting the severed piece or board laterally to the rollers 53.

The actuating means for the shaft 127 may be of any suitable kind, and as shown in Fig. 10, includes a pinion 132 connected, as at 133, to the shaft 127, and meshing with a gear wheel'134 having a ratchet wheel 135 secured thereto. An oscillating arm 136 has a pawl 137 engaging the ratchet wheel 135, and is connected by a link or rod 138 to a lever, such as the lever 91 in Fig. 4, to operate the sprocket chain 126 similar to the feed bar 62 above described. Thus, when the rod 138 is pulled, to swing the arm 136, the gear wheel 134 is rotated through an arc to turn the fpinion 132, whereby the shifter lugs 131 o the sprocket chains 126 are moved to and along the surface ofthe table 32 to engage the edge of the severed piece of the board and shift it laterally between the rollers 53, which will carry and move it onto the table 43' and the chains 126 will then come to rest for the next operation, the arm 136 being" returned to normal position.

A similar shifting device is used for the table 43 for shifting the piece of board .lengthwise to the scoring or creasing and cutting device, which is located at one end of the table 43, including the shafts 57' carried by the frame at said end of the table 43', and on which the creasing or scoring rollers 60 and cutters 61 are located, similar to the device above described carried by the shafts 57. Thus, this device is located at one end of the table as seen in Fi 9 instead of at one side edge thereof, there y creasing or scoring and cutting the piece lengthwise instead of laterally as in the first described arrangement. A slide 120' is ad'ustable longitudinally under the table 43', y means of an adjustmgscrew 123, and carries transverse shafts 124' over which the sprocket chains 126 are trained, and a transverse shaft 127 carried by the frame drives the sprocket chains 126' similar to the shaft 127, andis operated by similar means to that shown in Fig. 10. The slide 120' can be ad- 'table, and

justed to accommodate pieces of board of different lengths. In adjusting the

slides

120 and 120 it is advisable to loosen the sprocket wheels on the

shaft

127 and 127, so that the

chains

126 and 126 will remain in proper position, without disturbing the normal position of the shifter lugs thereon, and after the slides have been adjusted to the width and length of the piece of board, the sprocket wheels can then be tightened on said

shafts

127 and 127. v

The operation of the modified construction is about the same as that hereinbefore described, with some variations. Thus, the severed piece of board is shifted by the chains 126 between the rollers 153, which advance the piece laterally on the table 43 and chains 126, under the presser plate 46 which has been raised. After receiving the pressure by the depression of the plate 46, said plate is raised, and the chains 126' are then operated to move the piece of board lengthwise to and through the creasing or scoring and cutting device at the endof said table 43 thereby ejecting the board lengthwise and'creasing or scoring and cutting it in the same direction.
