United States Patent 3,455,767 DOUBLE DECK SINGLE FACER MACHINE Hans Meister, Cherry Hill, N.J., assignor to Samuel M. Langston Company, Camden, N.J., a corporation of New Jersey Filed Aug. 17, 1965, Ser. No. 480,453 Int. Cl. B32b 31/12, 3/28 US. Cl. 156-470 9 Claims ABSTRACT OF THE DISCLOSURE that they are interchangeable.

This invention relates to a double deck single facer machine, and more particularly to such a machine structurally interrelated in a novel manner.

In accordance with the present invention, two single facer machines having identical frames are disposed at different elevations in a staggered fashion whereby only the front end of the upper machine is supported by the lower machine. A discrete support means is provided to cooperate with the lower machine for supporting the upper machine. Since the frames on each of the machines are identical, only one production line is required for the frames and either machine could be an upper or a lower. The components of each machine are identical and therefore there is no need for manufacturing or storing components which are usable only on one of the machines. Also, the upper and lower machines are structurally interrelated in a manner so that the corrugating rolls and other components of the lower machine may be removed without interfering with the upper machine.

The staggered arrangement of the machines has other advantages. Thus, maintenance and observation of components such as doctor rolls, adhesive flow patterns, clean-out fingers, adjustment of crescent fingers, etc. are capable of being accomplished on either machine as if the other machine were not present. The individual machines are structurally interrelated in a manner whereby a paperboard manufacturer may install only the lower machine and at some later date, add the upper machine thereto. This event could occur when a manufacturer does not have a sufficiently large business so as to justify a double deck arrangement. By adding an upper deck at some later date, the manufacturer has the advantage that additional floor space is not required.

Quite often, manufacturers move from one location to another, such as during an expansion program. In the event that such changes do not facilitate the use of double deck machines and adequate space is available, the upper deck may be removed and mounted on a bed plate whereever desired. Thus, it will be noted that maximum versatility is one of the main advantages of the present invention in conjunction with the other advantages discussed above.

A single motor may be used to drive rotating components of the upper and lower deck. The drive system preferably includes provisions for declutching the corrugating and pressure rolls of either machine independently ice of the other. At the same time, this system may include components for declutching the drive with respect to the glue mechanism independently of each other and independent of the driving connection to the corrugating and pressure rolls. The driving system of the present invention permits the accomplishment of these features While being simple, rugged, and inexpensive.

It is an object of the present invention to provide a novel double deck single facer machine.

It is another object of the present invention to provide a double deck single facer machine having identical upper and lower modules structurally interrelated in a staggered fashion.

It is another object of the present invention to provide a double deck single facer machine structurally interrelated in a manner to facilitate ease of maintenance and observation of components.

It is another object of the present invention to provide a double deck single facer machine having upper and lower modules each provided with identical frames so that either one could be an upper or a lower deck.

It is another object of the present invention to provide a double deck single facer machine comprised of upper and lower decks structurally interrelated in a manner whereby the upper deck may be added after the lower deck has been installed and operated.

Other objects will appear hereinafter.

For the purpose of illustrating the invention, there is shown in the drawings a form which is presently preferred; it being understood, however, that this invention is not limited to the precise arrangements and instrumentalities shown.

FIGURE 1 is a side elevational view of the machine at the present invention.

FIGURE 2 is a sectional view taken along the line 22 in FIGURE 1.

FIGURE 3 is a sectional view taken along the line 33 in FIGURE 2.

FIGURE 4 is a slightly enlarged detailed view of the structure within the circle designated as A in FIGURE 2.

FIGURE 5 is a transverse sectional view of the lower single facer machine.

Referring to the drawings in detail, wherein like numerals indicate like elements, there is shown in FIGURE 1 a double deck single facer machine in accordance with the present invention designated generally as 9. The machine 9 includes a lower single facer machine 10 and an upper single facer machine 11. The machines 10 and 11 are identical modules having identical frames.

The single facer machines 10 and 11 are each preferably of the type disclosed in copending application Ser. No. 480,415 entitled Single Facer Machine and filed on Aug. 17, 1965, and now US. Patent No. 3,390,040. The disclosure in said application is incorporated herein by reference. Since the structure of the machines 10 and 11 is identical, only the details of machine 10 will be described in detail hereinafter.

The machine 10 includes a pair of parallel spaced side frames which may be designated as a right side frame 12 in FIGURE 3 and a left side frame 14. The

side frames

12 and 14 support the rotating components and are mounted on a bed plate 16. The

frames

12 and 14 are connected to the bed plate 16 by front and rear pairs of bolts disposed on the inner surfaces of the frames. The distance between the bolts of each pair is identical. The side frames are preferably solid cast iron and the bed plate 16 is preferably sound-deadened to eliminate vibration problems.

A first or lower corrugating roll 18 is rotatably supported by the

side frames

12 and 14. A second or upper corrugating roll 20 is rotatably supported by a pair of lever arms 22 (only one of which is shown). The arms 22 are mounted on the

side frames

12 and 14 for pivotable movement about the longitudinal axis of stud 24. The arms 22 are each connected to a rod extending from separate pneumatic motors 28 (only one shown). The motors 28 are adapted to operate in unison to move the ends of the upper corrugating roll 20 toward the lower corrugating roll 18 by pivoting the same about the longitudinal axis of stud 24.

A pressure roll 30 is supported for rotation about its longitudinal axis by the side frames 12 and 14. A conventional means not shown may be provided for heating the

rolls

18, 20 and 30. The pressure roll 30 is supported at its ends by arms 32 (only one of which is shown). The arms 32 are mounted for pivotable movement about the longitudinal axis of stud 34. The arms 32 are each likewise connected to a separate rod extending from a pneumatic motor 38 (only one of which is shown). The motors 38 are adapted for simultaneous actuation to move the ends of the pressure roll 30 toward the lower corrugating roll 18 by pivoting the arms 32 about the longitudinal axis of stud 34.

The axes of the

rolls

18, 20 and 30 lie substantially in a plane which is inclined with the horizontal. The axes of

studs

24 and 34 lie in a plane which is substantially parallel to the last-mentioned plane. The

motors

28 and 38 all lie in a plane inclined with the horizontal and parallel to the last-mentioned planes.

The

pneumatic motors

28 and 38 on one side of the machine are mounted on a support member 36. The

motors

28 and 38 on the other side of the machine are likewise supported by corresponding support members. The support members 36 are bolted to the side frames 12 and 14 in a manner whereby their removal exposes the bearings for the roll 18. In this manner, access for maintenance or removal of these rolls is readily facilitated. It has been found that this construction will enable removal or replacement of the lower corrugating roll with a period of several hours instead of several days.

The medium 46 to be corrugated passes over a spreader bar 39 adjustably supported by the side frames 12 and 14. The spreader bar 39 assures smooth entry of the medium 46 as will be readily understood by those skilled in the art. From the spreader bar 39, the medium 46 may pass oves one or more idler rollers and beneath a shower designated generally as 40. The desirability of providing a shower for preheating and conditioning the medium 46 will be readily understood by those skilled in the art. If desired, a slitter knife may be provided between the shower and the spreader bar 39 to trim side edges of the medium 46.

After preconditioning, the web of medium 46 passes over the upper corrugating roll 20 and into the nip between the corrugating rolls 18 and 20 whereby flutes are formed under heat and pressure. The newly formed flutes are gently stripped from the nip by one-piece crescent fingers 54 at spaced points therealong and guided around the corrugating roll 18. A liner 48 extends around the preheater roll 42, around idler roller 44, passes between the nip of

rolls

18 and 30, and is adhesively bonded to the corrugated medium 46 by the heated pressure roll 30 to thereby form single faced board 50 which exits in the direction of arrow 52.

Crescent fingers 54 are disposed at spaced points along the corrugating rolls. The upper corrugating roll 20 is provided with grooves at spaced points therealong to facilitate receiving the upper end of the crescent fingers 54, The crescent fingers 54 are adjustably supported by a rigid finger bar 56 extending between and connected to the side frames 12 ad 14. The fingers 54 confine the corrugated medium 46 to the teeth of the roll 18, but permit it to fluff out very slightly while adhesive is applied to the flute tips by an adhesive applicator roll 62. To facilitate such slight flufiing out, the fingers 54 are provided with a depression or notch in the area between

rolls

18 and 62.

The adhesive or glue applicator roll 62 is provided with a peripheral adhesive applicating surface interrupted at spaced points therealong by grooves 64. A metering roll 66 is provided to meter the thickness of adhesive on the surface of roll 62. As the medium 46 fluffs out into the relief section on the crescent fingers 54, an even film of adhesive is applied on the flute tips by the outer peripheral surface of roll 62.

Power cylinders 72 (see FIGURE 5) are supported by the frames below the horizontal plane of the glue pan for retracting the glue mechanism which includes the glue pan 68, applicator roll 62 and metering roll 66. The cylinders 72 may be identical in size with the

power cylinders

28 and 38 for simplification of maintenance and storage of spare parts. The cylinders 72 are pneumatic and have a rod 74 extending upwardly for connection to the glue pan 68.

A bracket 76 is provided at each end of the glue pan 68. The glue pan 68 and the

rolls

62, 66 are supported by the brackets for pivotable movement about a horizontal axis corresponding to the longitudinal axis of shaft 78. Shaft 78 is longer than the distance between the side frames 12 and 14. The side frames 12 and 14 are rigidly interconnected by a cylindrical brace 80.

Free floating clean-out fingers 82 are provided. Each clean-out finger 82 extends into one of the grooves 64 on roll 62. The clean-out fingers maintain the proper amount of adhesive in the grooves 64. The entirety of the clean-out fingers lies between vertical planes containing the axes of the

rolls

62 and 66. Back-up structure in the form of a shaft 84 may be provided to limit the upward extent of the clean-out fingers 82. Since the clean-out fingers 82 are free-floating, they are self-adjusting with speed changes and mounted for removal from a position above the glue pan 68 and do not interfere with the adjustment of dams or partitions within the glue pan.

In order to facilitate adjustment in the gap between the applicator roll 62 and the corrugating roll 18, arms 96 are fixedly secured to the ends of shaft 78 on the outer surface of the side frames 12 and 14. A limit stop 98 is provided on each side frame for cooperation with an adjustable screw member 100 which is threadedly coupled to the terminal end of each arm 96.

The

frames

12 and 14 terminate at their upper ends in a horizontal surface 102. Surface 102 is provided with a pair of tapped holes spaced apart by a distance corresponding to the distance between the bolts of each pair connecting the frames to the bed plate 16. In this manner, bolts 104 may be utilized to connect the front end 106 of machine 11 to the surface 102 on the rear end of the machine 10 as shown more clearly in FIGURE 3. A discrete support means such as

posts

108 and 110 are provided to cooperate with the machine 10 in supporting the upper single facer machine 11. The upper end of

posts

108 and 110 are provided with apertures spaced apart by a distance corresponding to the distance between the bolts of the pair of bolts securing the rear end of machine 10 to the bed plate 16. Hence, the same bolts and apertures which could be used to bolt the rear end of machine 11 to a bed plate are utilized to bolt the rear end of machine 11 to the support posts 108 and 110.

The bed plate 16 is provided with apertures adjacent each end thereof for receiving bolts 112. Bolts 112 secure an extension 114 thereto at ground level. Each of the extensions 114 support the lower end of one of the

posts

108 and 110. The tapped holes in surface 102' at the upper end of machine 11 (see upper lefthand corner of FIGURE 1) are not used and may befilled with a dummy bolt if desired. Such dummy bolts would prevent these tapped holes from becoming filled with dirt or other impurities and thereby interfere with the ability of machine 11 being used at some subsequent time as the lower deck of a double deck machine.

To facilitate access to the front of the machine 11, the lower machine may be provided with a catwalk platform 116. Platform 116 may be removably bolted to the support 36 which are spaced apart further than the greatest width of paperboard which can :be processed so as not to interfere with the exit of single faced board. The use of discrete support means for the rear end of machine 11 of the upper deck facilitates ease of maintenance and operation of both machines without interfering with either machine. Access to the rear side of machine 11 may be had by way of any elevated platform. The machines 10 and 11 are capable of being operated independently of one another and are adapted to function as if the other did not exist.

The double deck machine 9 is provided with a single driving system which provides for selective or simultaneous operation of the machines 10 and 11. The driving sys tem includes a motor 118 mounted on a base 120. Base 120 may be separate from or connected to extension 122 of the bed plate 16.

The motor 118 is provided with a V-belt pulley 126. Belts 128 extend around the

pulleys

124 and 130 and in engagement with idler pulley 132.

A vertical plate 134 is bolted at its lower end to the extension 122 spaced from and parallel to the side frames of the machines 10 and 11. Plate 134 is provided with a horizontal surface 136 at its upper end and a horizontal surface 138 between its upper and lower ends. A shaft 140 is supported on surface 136 by hearing 142. The hub 144 of pulley 130 is rotatably supported on shaft 140 and connected to one side of a pneumatic selectively operable clutch 146. The rotary motion of hub 144 may be selectively transmitted to the shaft 140 by way of clutch 146. Clutch 146 may be conventional.

The end of shaft 140 remote from clutch 146 is rotatably supported by side frame 150 on the machine 11. Side frame 150 on machine 11 corresponds to side frame 14 on machine 10 and are disposed one above the other, but staggered with respect to each other as shown more clearly in FIGURE 3. The side frame of machine 11 opposite from side frame 150 is designated as 152. Side frame 152 corresponds to side frame 12 on machine 10.

Shaft 140 is provided with a gear 154 adapted to be coupled to drive the lower corrugating roll on machine 11. The upper corrugating roll on machine 11 is designated as 156. Due to the position where FIGURE 2 was taken, the lower corrugating roll 157 on machine 11 does not appear in FIGURE 2. The gear for rotating roll 157 is designated as 159 and is a meshing engagement with gear 154.

A gear 162 surrounds shaft 140 and is fixedly secured to the hub 144. The drive from gear 162 to gear 170 is by means of an intermediate gear 164 which can be engaged or disengaged from gear 162. Gear 162 in the arrangement illustrated is in meshing engagement with a gear 164 rotatably supported by a plate 166. Plate 166 is rotatably supported by shaft 168 which in turn is journaled in a bearing on the upright plate 134. A gear 170 is keyed to shaft 168 and in meshing engagement With gear 164.

The shaft 168 is connected by a universal joint shaft 172 to glue applicator roll 158. Gear 176 is connected by an endless chain to a gear 178 for driving the metering roll 160 at a slower speed. Roll 158 on machine 11 corresponds to applicator roll 62 on machine 10. The metering roll 160 corresponds with the metering roll 66 on machine 10.

In order to provide for rotation of plate 166 and gear 164 which is supported thereby, a handle 186 is connected at one end to the plate 166.

The coupling between the drive system and the lower machine 10 is identical with that described above the connection with machine 11. Thus, it is not deemed necessary to explain the corresponding structure of machine 10 in detail, except to point out that a shaft corresponding to shaft 140 is supported by a bearing on surface 138. The idler pulley 132 is adjustably supported on the plate 134 to facilitates adjustment of the tension of belt 128 by means of bolt 196 and parallel slots 198 in plate 134.

With the motor 118 running, and the air clutches en gaged on machines 10 and 11, the corrugating roll and glue applicator roll of each machine are rotating. If it is desired to stop rotation of the corrugating roll 157 of machine 11, clutch 146 is disengaged. With clutch 146 disengaged, the applicator roll of machine 11 is still rotating. If it is desired to stop the rotation of the glue applicator roll of machine 11, regardless of whether the corrugating roll 157 is rotating, it is only necessary to rotate the handle 186. This will result in

gears

162 and 164 being out of mesh.

Regardless of the operative or inoperative disposition of the components of machine 11, the rotation of the glue applicator roll 62 and corrugating roll 18 of machine 10 may be independently controlled by operation of the corresponding clutch 146 and/or handle 186.

The platform 116 is removable and need not be present when there is no upper deck. The platform 116 facilitates access to the machine 11 when it is an upper deck machine.

As pointed out above, the distance between the sets of bolts connecting the lower single facer machine frame to the bed plate 16 corresponds to the distance between adjacent bolts 104 connecting the front end 106 of machine 11 to the rear end of machine 10 at surface 102. Said distance also corresponds to the distance between the bolts connecting the rear end of machine 11 to the upper end of

support posts

108 and 110. These relationships facilitate using either machine 10 or 11 as an upper or a lower or by themselves without requiring any additional adaptors or machines thereby lending versatility to the single facer machine 11.

If machine 11 is not present, machine 10 will be operating with a smaller version of plate 134 and a belt shorter than belt 128 and of sufficient length to couple pulley 124 to pulley 126. When machine 11 is superimposed on a machine 10, the only change of components involved in the conversion to the double deck machine of the present invention is to removed the old belt together with the smaller version of plate 134 and substitute belt 128 and plate 124 therefor.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof and, accordingly, reference should be made to the appended claims, rather than to the foregoing specification as indicating the scope of the invention.
