Definitions

  • This invention relates to apparatus for applying adhesive substances to. bands of paper or the like and for feeding the said bands to boxes or other articles to be covered.
  • the band to be glued is drawn forward as required over a light roller immersed in the glue contained in a tank arranged below the roller.
  • the paper is placed on the box or the like by hand, one side at a time, so that it is not usually drawn ofi' continuously: while one face of the box is being 7 covered the band is stationary, the box is then turned to bring another face into position when another length is drawn forward; the paper feed is therefore usually intermittent, and difficulty has been found in overcoming the inertia of the gluing roller, with the result that the band slipped forward over the surface of the gluing roller and a portion of the band failed to receive a sufliclent quantity of glue. Efforts have been made to overcome this objection by dispensing with the usual stripping roller, but
  • the chief object of the present invention is to provide a banding machine in which thevarious objections mentioned above are overcome; other objects are to provide a banding machine in which the paper will not stick to the roller and the glue is not liable to dry upon the gluing roller when the machine is temporarily stopped, and in which waste of the paper or other band is avoided.
  • Figure l is a side elevation of one end of the improved banding machine.
  • Fig. 2 is a similar view of the opposite end of the machine.
  • Fig. 2 is a detail side elevation of the starting frame and its adjacent parts.
  • Fig. 3 being a section of the same taken on the line 3-3 of Fig. 2, and Fig. 4, a plan of same; and
  • Fig. 5 is a plan; and
  • Fig. 6 is a side elevation of a portion of yet another construction of banding machine according to my invention.
  • Figs. 1 to 4 of the drawings there is shown a construction of banding machine having means for drivin the gluing roller positively.
  • the band A is shown passing from the roll A over a guide roller D mounted upon a. bracket a, under the roller C of the starting device, over the gluing roller B, under a guide roller D and through the shearing apparatus S.
  • the machine is driven from the main shaft G, which is mounted in suitable brackets 9 carried by the main frame f and is driven continuously by a pulley g; the main shaft G also carries a beveled friction disk G and a pulley G the gluing roller 13, and consequently the paper feed, is driven from the pulley G and the box-spindle is driven from the beveled disk G.
  • the gluing roller is driven through a belt G, a pulley H, a friction disk H running with its periphery in contact with the faces of the pulley H and a disk H having a milled flange I- a disk J, a pinion J (Fig. 3), and a pinion E the pulley H is mounted upon a shaft it carried in bearings h upon the main frame f of the machine and is pressed inward toward the disk H by a spring 7L (Fig.
  • the intermediate disk i is mounted upon a stud it carried by an arm lz/ pivoted upon a rod m that is adapted to slide in bearings m mounted upon the main frame;
  • the pulley is mounted upon the shaft /2 and is acted upon by the helical spring h threaded upon the shaft 71 between a collar h and the face of the bracket carrying the bearing in;
  • the disk J and the pinion J are fiXed'on the opposite ends of a short shaft J 2 carried in a boss at the lower end of the arm J of a two-armed lever J 3 J 4 fixed upon a shaft j carried in a.
  • bracket j and coaxial with the shaft 5 carrying the gluing roller, the disk J being-- at the proper momentadapted to come into contact with the milled flange H while the pinion J is constantly in gear with the pinion B which is secured upon the shaft 12 carrying the gluing roller B.
  • the starting device consists of the roller C and a frame C this frame-of which only one arm is shown in Fig. 2 is secured upon a shaft C pivoting in fixed bearings C? and carrying at one end a bar C which, since the other end of the frame is the heavier, rests normally against the underside of the bar M of the main frame.
  • a set-screw G is'adjusted against the arm J of the lever J 3 J 4 so that the friction disk J is out of contact with the milled flange H, this adjustment being effected against 7 the action of a spring J 5 secured at one end to the main frame and at the other to a rod J 6 fitted with one end in a hole in the shaft j upon which the lever J 3 J 4 is fixed; the rod J 6 is notched to facilitate the adjustment of the spring thereon, and'by adjusting the spring upon the rod to give it the necessary tension, the system may be'nicely balanced so that the weight of the roller C and the right-hand portion of the frame (3 acting through the set screw G and the arm J 4 is just sufficient to keep the friction disk J out of contact with the revolving milled flange H
  • the frame (1 being rocked upward about its pivot C this relieves the pressure, through the set-screw C of the starting device G C upon the arm J of the two-armed
  • the box-spindle N is driven, in the usual way, from the main shaft G through the beveled friction disk G, a similar disk L on the side shaft L, a worm L on the said shaft L, and a worm wheel N mounted upon the box spindle:
  • the beveled disk G is at liberty to slide longitudinally upon a key fixed in the shaft G, and is normally out of contact with the beveled friction disk L which is secured upon the shaft L, but upon the pedal Gr being pressed by the operator the disk G is moved against the disk L thus causing the spindle N to be rotated and with it the box or other articles around which the band is wrapped, the operator having previously drawn the free end of the band forward and stuck it to the end of the box, all in the usual manner.
  • the position of the intermediate disk H is adjusted relatively to the pulley H, by the longitudinal movement of the rod on, and the disk H until the length delivered the gluing roller B for each rotation of the box spindle N corresponds to the sum of the length of the sides of each box bemg covered.
  • the speed of the box-spindle is practically regular, but when oblong boxes are being covered the said speed must vary from a maximum to a minimum twice during a revolution of the box, the maximum taking place when the long side of the box is passing vertically over the spindle N.
  • box-spindle N is provided with a pinion N gearing with a pinion N half the size of the pinion l 2 sothat the pinion N revolves twice to the pinion N once; across the face of the pinion N is a crankmember N provided with a slot N in which a stud N can be fixed at any desired distancefrom the center of the wheel N or on the centeritself; and a connecting rod is hinged on the stud N at one end and on a stud N attached to the sliding rod m, at the other end.
  • the roll of paper A is carried on a shaft A and alight brake A pivoted at A is pressed by an adjustable weight A
  • the roll of paper is thus prevented from overrunning, and also offers a slight resistance to the pull of the band, which is made suflicient to drive the gluing roller or lift the roller C as described.
  • a transverse rod C is arranged below the roller C of the starting appliance, the band passing between the roller C and rod G a handle C is provided for the appliance and is loosely pivoted on the rod C; by means of the handle C the startingappliance frame C may be rocked into the position indicated by broken lines in Fig. 2* when a notch C engages with a pin M on the main frame.
  • the brake j is also useful in that it brings the gl'uingrollcr B quickly to rest when a boxhasbeen covered; this is particularly necessary when large boXes are being covered, because-in such case large lengths of band are drawn rapidly through the machine and the gluing and stripping rollers acquire so much momentum that they are liable to continue running even after the disk J has moved out of contact with the flange H
  • the brake block 7' the friction disk is stopped quickly immediately the tension on the band ceases and the starting appliance falls on to the arm J.
  • a glue tank F of ordinary construction is mounted upon the main frame F, and in it the gluing roller B is free to rotate upon its shaft 6 mounted in fixed bearings b (Fig 3) the spur wheel B in addition to gearing with the pinion J alsogears with a spur wheel E upon the shaft 6 of the stripping roller E and the shaft 6 ismountedin bearings e which are adjustable by means "of screws 6 so that the distance between the rollers B and E can be adjusted withthe utmost nicety in order that when they revolve only a thin film of adhesive material is carried over .by the gluing roller B and deposited upon the band A.
  • Figs. 5 and 6 illustrate an apparatus for simultaneously gluing a'main band, which may be plain and comparativelywide, and twocomparatively narrow border bands.
  • the glulllg tank T is extended, the usual (or pri- -mary) gluing roller B is employed for the main band, and there is provided a secondary gluing roller B over which the border bands (one of which is indicated by A in Fig. 6) are drawn from rolls that turn about anaXis or axes parallel to the axis of the roll from which the main band is drawn.
  • the border-bands are so arranged longitudinally upon the second gluing roller that when" all of'the bands are drawn together under the guide'roller D (after leaving the gluing r Here) they have the required amount ofoverlap without adjustment by guides or the like.
  • the gluing rollers 13, B are geared to gether by spur wheels B E, 7s, 7s, and B soas to be capable of both being driven positively as described above in connection with the apparatus shown in Figs. 2 to l, and the gluing roller B is provided with a band-engaging device'C similar to the device C, C C C shown in Figs. 2 and a and connected to the latter device by a link It whereby, when the machine is temporarily stopped, all of the said bands may be simultaneously moved away from the gluing rollers B B while the latter are rotated as and for the purposes set out above.
  • the intermediary gear wheels 7: 7c are equal in size and are-mounted upon shafts carried in bearings upon a pair of brackets (K) mounted upon the frame of the ma chine as shown in the drawings.
  • the rod or link R is connected to therappliance C by means of a slot R with which a pin 5* engages so as to allow of a certain amount of relative movement between the two appliances, since the appliance C, G etc, acts as a starting appliance.
  • One of the arms of the supplementary appliance C" is provided with an extension 0 adapted to rest upon the edge of the glue tank or upon a bracket connected thereto and to act as a stop to determine the position of the said appliance.

Specification of Letters Patent.
Patented Dec. 1?}, 1916.
Application filed February 8, 1912. Serial No. 676,365.
To all whom it mag/ concern:
Be it known that 1, JOHN WILLIAM NAS- MITH, of Heaton Mersey, Lancashire, England, have invented certain new and useful Improvements in Banding-Machines, of which the following is a specification.
This invention relates to apparatus for applying adhesive substances to. bands of paper or the like and for feeding the said bands to boxes or other articles to be covered.
In apparatus of this kind, which will be hereinafter termed banding machines, the band to be glued is drawn forward as required over a light roller immersed in the glue contained in a tank arranged below the roller. The paper is placed on the box or the like by hand, one side at a time, so that it is not usually drawn ofi' continuously: while one face of the box is being 7 covered the band is stationary, the box is then turned to bring another face into position when another length is drawn forward; the paper feed is therefore usually intermittent, and difficulty has been found in overcoming the inertia of the gluing roller, with the result that the band slipped forward over the surface of the gluing roller and a portion of the band failed to receive a sufliclent quantity of glue. Efforts have been made to overcome this objection by dispensing with the usual stripping roller, but
receives an unnecessary amount of adhesive most of which has to be removed by drawing the paper over scrapers, and the machine must therefore be made sufficiently long to allow of this and to allow the glued side of the band to be exposed long enough to dry partially before reaching the box.
The chief object of the present invention is to provide a banding machine in which thevarious objections mentioned above are overcome; other objects are to provide a banding machine in which the paper will not stick to the roller and the glue is not liable to dry upon the gluing roller when the machine is temporarily stopped, and in which waste of the paper or other band is avoided.
These and other featuresof the invention will now be described with reference to the accompanying drawings in which' Figure l is a side elevation of one end of the improved banding machine. Fig. 2 is a similar view of the opposite end of the machine. Fig. 2 is a detail side elevation of the starting frame and its adjacent parts. Fig. 3 being a section of the same taken on the line 3-3 of Fig. 2, and Fig. 4, a plan of same; and Fig. 5 is a plan; and Fig. 6 is a side elevation of a portion of yet another construction of banding machine according to my invention.
In Figs. 1 to 4 of the drawings there is shown a construction of banding machine having means for drivin the gluing roller positively. In the said gures the band A is shown passing from the roll A over a guide roller D mounted upon a. bracket a, under the roller C of the starting device, over the gluing roller B, under a guide roller D and through the shearing apparatus S.
The machine is driven from the main shaft G, which is mounted in suitable brackets 9 carried by the main frame f and is driven continuously by a pulley g; the main shaft G also carries a beveled friction disk G and a pulley G the gluing roller 13, and consequently the paper feed, is driven from the pulley G and the box-spindle is driven from the beveled disk G.
The gluing roller is driven through a belt G, a pulley H, a friction disk H running with its periphery in contact with the faces of the pulley H and a disk H having a milled flange I- a disk J, a pinion J (Fig. 3), and a pinion E the pulley H is mounted upon a shaft it carried in bearings h upon the main frame f of the machine and is pressed inward toward the disk H by a spring 7L (Fig. 3); the intermediate disk i is mounted upon a stud it carried by an arm lz/ pivoted upon a rod m that is adapted to slide in bearings m mounted upon the main frame; the pulley is mounted upon the shaft /2 and is acted upon by the helical spring h threaded upon the shaft 71 between a collar h and the face of the bracket carrying the bearing in; and the disk J and the pinion J are fiXed'on the opposite ends of a short shaft J 2 carried in a boss at the lower end of the arm J of a two-armed lever J 3 J 4 fixed upon a shaft j carried in a. bracket j and coaxial with the shaft 5 carrying the gluing roller, the disk J being-- at the proper momentadapted to come into contact with the milled flange H while the pinion J is constantly in gear with the pinion B which is secured upon the shaft 12 carrying the gluing roller B.
The starting device consists of the roller C and a frame C this frame-of which only one arm is shown in Fig. 2 is secured upon a shaft C pivoting in fixed bearings C? and carrying at one end a bar C which, since the other end of the frame is the heavier, rests normally against the underside of the bar M of the main frame. A set-screw G is'adjusted against the arm J of the lever J 3 J 4 so that the friction disk J is out of contact with the milled flange H, this adjustment being effected against 7 the action of a spring J 5 secured at one end to the main frame and at the other to a rod J 6 fitted with one end in a hole in the shaft j upon which the lever J 3 J 4 is fixed; the rod J 6 is notched to facilitate the adjustment of the spring thereon, and'by adjusting the spring upon the rod to give it the necessary tension, the system may be'nicely balanced so that the weight of the roller C and the right-hand portion of the frame (3 acting through the set screw G and the arm J 4 is just sufficient to keep the friction disk J out of contact with the revolving milled flange H When the end of the band A is pulled the roller C is raised, the frame (1 being rocked upward about its pivot C this relieves the pressure, through the set-screw C of the starting device G C upon the arm J of the two-armed lever J J and allows the spring J to rock the said twoarmed lever until the friction roller J comes into contact with the flange I" of the continuously driven disk H with the result that motion is transmitted from the shaft G to the roller 13 through the various parts mentioned above.
The box-spindle N is driven, in the usual way, from the main shaft G through the beveled friction disk G, a similar disk L on the side shaft L, a worm L on the said shaft L, and a worm wheel N mounted upon the box spindle: the beveled disk G is at liberty to slide longitudinally upon a key fixed in the shaft G, and is normally out of contact with the beveled friction disk L which is secured upon the shaft L, but upon the pedal Gr being pressed by the operator the disk G is moved against the disk L thus causing the spindle N to be rotated and with it the box or other articles around which the band is wrapped, the operator having previously drawn the free end of the band forward and stuck it to the end of the box, all in the usual manner.
To prevent more paper from being fed forward than is required for a single box, the position of the intermediate disk H is adjusted relatively to the pulley H, by the longitudinal movement of the rod on, and the disk H until the length delivered the gluing roller B for each rotation of the box spindle N corresponds to the sum of the length of the sides of each box bemg covered.
If the boxes are square or thereabout the speed of the box-spindle is practically regular, but when oblong boxes are being covered the said speed must vary from a maximum to a minimum twice during a revolution of the box, the maximum taking place when the long side of the box is passing vertically over the spindle N. To provide for this the box-spindle N is provided with a pinion N gearing with a pinion N half the size of the pinion l 2 sothat the pinion N revolves twice to the pinion N once; across the face of the pinion N is a crankmember N provided with a slot N in which a stud N can be fixed at any desired distancefrom the center of the wheel N or on the centeritself; and a connecting rod is hinged on the stud N at one end and on a stud N attached to the sliding rod m, at the other end. By this mechanism the rod on will be moved to and fro twice while the box spindle N revolves once, consequently the friction disk H will be moved to and fro between the pulley H and the disk H and will accelerate and retard the speed of the latter to an extent that depends upon the eccentricity of the stud N which can be adjusted to suit the boxes being covered.
The roll of paper A is carried on a shaft A and alight brake A pivoted at A is pressed by an adjustable weight A The roll of paper is thus prevented from overrunning, and also offers a slight resistance to the pull of the band, which is made suflicient to drive the gluing roller or lift the roller C as described.
Below the roller C of the starting appliance a transverse rod C is arranged, the band passing between the roller C and rod G a handle C is provided for the appliance and is loosely pivoted on the rod C; by means of the handle C the startingappliance frame C may be rocked into the position indicated by broken lines in Fig. 2* when a notch C engages with a pin M on the main frame. Then this is done the band A is moved entirely clear of the gluing roller B; the arm J 4 of the lever J 3 J t is relieved of the weight of the starting appliance, and the spring J 5 rocks the lever J J until the disk J comes into contact with the flange H of the constantly rotating disk H with the result that the gluing roller is rotated, and this rotation continues until the starting device C C is moved back to its normal position as indicated in full lines (Fig. 2 The moving of the band away from the gluing roller and the continuous rotation of the latter during a temporary stoppage of the machine prevents the band from becoming stuck to the gluing roller and the glue on the latter from becoming hard and cracking.
When the band A is being moved clear of the gluing roller B the friction disk J swings into contact with the flange H OI the constantly rotating disk H and the consequent rotation of the gluing roller B is liable, ibefore the band can be moved out of eXtension J when the arms C are rocked upward any considerable distance and to rock the arms J in a counterclockwise direction until the disk J comes into contact with a brake shoe 9 mounted uponthe frame P 'nearto-the glue tank. Therefore so long as the starting appliance G G is merely rocked by'means of the band a sufficient dis tance to allow the arms 3 to be rockedby the spring J until the disk J bears upon thefiange H the cam (3 does Ilotlcome into operation; but when the starting appliance'is rocked a considerable distance by means of the handle C the cam comes into operation and "acts upon the extension J to cause the disk J to be swung into'contact with the brake-block j and after the cam C in turning with the arms (3 has ceased to act upon the arm J the spring J pulls the arms J 3 back in order to cause the disk J to come into contact with the flan e H so that the 'luin' or adhesive-.
applying roller B will be driven continuously while the band is in the raised position indicated by broken lines in Fig. 2* as described above. The brake j is also useful in that it brings the gl'uingrollcr B quickly to rest when a boxhasbeen covered; this is particularly necessary when large boXes are being covered, because-in such case large lengths of band are drawn rapidly through the machine and the gluing and stripping rollers acquire so much momentum that they are liable to continue running even after the disk J has moved out of contact with the flange H By providing the brake block 7' the friction disk is stopped quickly immediately the tension on the band ceases and the starting appliance falls on to the arm J. A glue tank F of ordinary construction is mounted upon the main frame F, and in it the gluing roller B is free to rotate upon its shaft 6 mounted in fixed bearings b (Fig 3) the spur wheel B in addition to gearing with the pinion J alsogears with a spur wheel E upon the shaft 6 of the stripping roller E and the shaft 6 ismountedin bearings e which are adjustable by means "of screws 6 so that the distance between the rollers B and E can be adjusted withthe utmost nicety in order that when they revolve only a thin film of adhesive material is carried over .by the gluing roller B and deposited upon the band A.
Referring now to the construction shown in Figs. 5 and 6; these figures illustrate an apparatus for simultaneously gluing a'main band, which may be plain and comparativelywide, and twocomparatively narrow border bands. In this construction the glulllg tank T is extended, the usual (or pri- -mary) gluing roller B is employed for the main band, and there is provided a secondary gluing roller B over which the border bands (one of which is indicated by A in Fig. 6) are drawn from rolls that turn about anaXis or axes parallel to the axis of the roll from which the main band is drawn. The border-bands are so arranged longitudinally upon the second gluing roller that when" all of'the bands are drawn together under the guide'roller D (after leaving the gluing r Here) they have the required amount ofoverlap without adjustment by guides or the like.
The gluing rollers 13, B are geared to gether by spur wheels B E, 7s, 7s, and B soas to be capable of both being driven positively as described above in connection with the apparatus shown in Figs. 2 to l, and the gluing roller B is provided with a band-engaging device'C similar to the device C, C C C shown in Figs. 2 and a and connected to the latter device by a link It whereby, when the machine is temporarily stopped, all of the said bands may be simultaneously moved away from the gluing rollers B B while the latter are rotated as and for the purposes set out above.
The intermediary gear wheels 7: 7c are equal in size and are-mounted upon shafts carried in bearings upon a pair of brackets (K) mounted upon the frame of the ma chine as shown in the drawings.
The rod or link R is connected to therappliance C by means of a slot R with which a pin 5* engages so as to allow of a certain amount of relative movement between the two appliances, since the appliance C, G etc, acts as a starting appliance.
One of the arms of the supplementary appliance C" is provided with an extension 0 adapted to rest upon the edge of the glue tank or upon a bracket connected thereto and to act as a stop to determine the position of the said appliance. The arms of the said supplementary appliance are pivoted at C11 upon the bracket K.
