Definitions

  • This invention relates to apparatus for automatically wrapping articles, and more particularly to apparatus for neatly wrapping boxes of arbitrary size.
  • the typical wrapping machine found in the supermarket for applying heat-seal film to packages of butchered meat presents a clear face on the top for display of the meat and hides all the gathered ends and spare film on the bottom of the package.
  • the machine works well in the supermarket for wrapping butchered meat, but would not do an adequate nob of wrapping gifts.
  • Another class of machine is available for high speed application of preprinted, precut wrappers to product, such as candy bar wrappers to candy bars. While the finished package is attractive and neatly wrapped, the product is usually of a single size, and the wrappers are precut to accommodate that single size.
  • the requirements on such a machine are that the finished wrapped package be neatly and attractively completed. Considering that the packages can be of any arbitrary size within limits, the ability to meet that requirement is not straight forward. If it is attempted to meet the requirement by using precut sheets which are large enough to accommodate the largest box, difficulty will be encountered m presenting a neat appearance m the wrapped package for boxes which are smaller than the maximum size.
  • a typical application for such machines is in gift wrapping.
  • department stores which offer a gift wrapping services the wrapping is usually done by hand. It is labor intensive, sometimes incapable of keeping up with peak demands, and oftentimes subject to variable quality of finished product.
  • hand wrapping whether the individual uses cut sheets or roll paper, the entire operation of trimming the sheet to size, placing the box on the sheet, folding the paper over the box and making the taped or glued attachments is done by hand using sight and with the judgment of the individual exercised at most steps of the process. Skill and judgment are required to reliably produce attractively wrapped packages on a regular basis.
  • a further object of the present invention is to provide such a machine which produces carefully formed angular folds giving the appearance of a hand-wrapped gift.
  • an object is to provide a package wrapping machine which is electronically controlled, which eliminates the need for pneumatic or hydraulic attachments, and which is operated under the control of a microprocessor.
  • a further objective is to provide programming capability for the microprocessor to allow the ready alteration of the basic functions of the machine under the control of an altered processor program.
  • the invention provides a package wrapping machine for boxes of arbitrary size.
  • An infeed section includes at least one and preferably a plurality of rolls of wrapping paper mounted to selectively unwind the paper therefrom.
  • An input section of the machine accepts a box of arbitrary size, and determines the dimensions of the box.
  • Programmed cutters cut a sheet of paper from the roll, the sheet having dimensions measured to wrap the box.
  • An adhesive applicator automatically applies adhesive to the box in a position to accept a leading edge of the cut sheet. Wrapping means then attaches the leading edge of the sheet to the adhesive covered portion on the box, wraps the box with the sheet, and attaches the trailing edge of the sheet to the partly wrapped box so that four sides of the box are wrapped, leaving two open ends. Fingers, adhesive applicators and wipers then fold and seal flaps at the two open ends thereby to produce a fully and automatically wrapped box.
  • the present invention also provides a subcombination which is generally as characterized above but which allows for non-automated hand-application of adhesive for securing the paper which is otherwise automatically cut, applied and folded to the package for wrapping it.

  • the invention is embodied in a package wrapping machine 30 suitable for gift wrapping, and sometimes referred to herein as gift wrapping machine.
  • the machine 30 is capable of accepting a box of arbitrary size, determining the dimensions of the box, withdrawing from a paper supply 31 a sheet of paper cut to an appropriate computed dimension to wrap the box, then advancing the sheet of paper and box into a wrapping station to wrap the box in the paper and tuck and secure the flaps to produce a completely gift wrapped box.
  • FIG. 1 shows the elements of a first embodiment of package wrapping machine 30 as comprising an infeed section 31 having a plurality of rolls of paper, preferably of different designs, widths or textures, and selectable for wrapping a particular box.
  • the illustrated embodiment shows four rolls 32-35 of paper, each having a free end held between an associated pair of nip rollers 36-39.
  • a paper infeed generally indicated at 40 supports the paper as it is withdrawn from the roll, and has a feed end 41 near an operative plane of the wrapping machine.
  • a box to be wrapped is advanced into a first station 40a by means of a computer controlled pusher assembly 43 which cooperates with a centering and measuring apparatus 44 intended to determine the three dimensions of the box, i.e., its length, its width and its height. It is these measurements which are used to determine the size of the sheet which is cut from the paper supply.

It is these measurements which are used to determine the size of the sheet which is cut from the paper supply.
  • adhesive is applied along one edge thereof, and the leading edge of the paper is advanced from the feed end 41 of the paper feed 40 to be secured to the box with the adhesive.
  • a wiper assembly generally indicated at 150 then wraps the paper around four sides of the box, ultimately securing the trailing edge over the leading edge.
  • a further pusher mechanism 45 moves the box into a second wrapping station generally indicated at 46.
  • the wrapping station 46 includes a turntable generally indicated at 47 which presents the unwrapped ends of the box to a flap-folding and fixing assembly generally indicated at 47a.
  • the flap-folding and fixing assembly tucks the flaps on the end, applies adhesive by means of an adhesive applicator 48, and utilizes a wiper mechanism 49 to secure the flaps.
  • the flap-folding and fixing assembly folds the paper along the four edges of the end face of the box to create flaps which are then sealed to prevent a neatly folded end face.
  • each edge of the box is done independently, and the turntable 47 rotates the box 180° after the first set of flaps are folded and fixed, whereupon the operation is repeated to fold and fix the second set of flaps.
  • the turntable 47 thereupon rotates 90° and delivers the box from the wrapping machine fully wrapped.
  • FIG. 1 shows the four paper supply rolls 32-35 as being fixed in a carriage 60 which can be translated in a vertical direction on sliding blocks 61, 62.
  • the vertical height of the carriage 60 is controlled by means of an electronic drive 63 operating through a chain drive 64, 65 secured to the carriage. Rotation of the motor 63 in one direction or the other serves to raise or lower the carriage 60.
  • the carriage 60 can be raised for loading new rolls of paper onto the hubs.
  • the carriage is automatically positioned to bring one of the rolls into an operative position.
  • FIG. 1 shows the four paper supply rolls 32-35 as being fixed in a carriage 60 which can be translated in a vertical direction on sliding blocks 61, 62.
  • the vertical height of the carriage 60 is controlled by means of an electronic drive 63 operating through a chain drive 64, 65 secured to the carriage. Rotation of the motor 63 in one direction or the other serves to raise or lower the carriage 60.
  • the carriage 60 can be raised for loading new rolls of paper onto the hubs.
  • the carriage is automatically positioned
  • the roll 32 is shown in the operative position in which the nip rollers 36 associated with the roll 32 are juxtaposed to the entrance end 67 of the paper feed 40.
  • the carriage 60 can be lowered to bring any of the other three sets of nip rollers 37, 38 or 39 into the operative position adjacent the infeed 67 of the paper feed 40.
  • the electronic controller selects one of the paper types for wrapping the particular box, and operates the elevator drive 63 to bring the nip rollers 36-39 of the selected roll 32-35 into the operative position. A sheet of paper is then cut from the supply roll, with the dimensions of the sheet matching the dimensions of the package to be wrapped.
  • the box to be wrapped can be of arbitrary size.
  • Measuring means are provided in the first station 40a for determining the dimensions of the box, and those mechanisms will be described below. Suffice it to say for the moment that the dimensions have been determined and are available to the processor for use in measuring and cutting a sheet of appropriate size from the supply roll.
  • both the length and width of the sheet are tailored to the dimensions of the box of arbitrary size to be wrapped.
  • the length of the sheet will be referred to as that 10 dimension capable of overwrapping the four sides of the box commonly called its top, its bottom, and two long sides.
  • the corresponding dimensions of the box will be called its length (see the dimension L in FIG. 14) and its height (see the dimension H in FIG. 14) .
  • the third dimension of the box, its width (see dimension W in FIG. 14) is the dimension transverse to the axis of box travel and the dimension of the box between the ends on which the flaps will be folded.
  • the length of the paper sheet will wrap two lengths of the box and two heights of the box, whereas the width of the paper will cover a single width of the box plus additional paper adequate to form flaps and folds at the two ends.
  • the longer dimension of the box will be that which is considered its width herein, and the definitions are selected simply as an aid in description and not in a limiting sense. It will be clear, after a complete description of the invention, that a rectangular box can be inserted into the gift wrapping machine in any of a plurality of orientations, whereupon it will be measured and wrapped, with a smooth sheet covering four sides defined herein as the length and height, and end flaps formed on the ends of the box separated by the dimension defined as the width.
  • the measuring apparatus in the station 42 determines the length, width and height of the box. Suffice it to say for the moment, that those dimensions have been determined and passed to the processor such that the processor can compute the length and width of the sheet to be cut from a selected roll.
  • the length of the sheet is computed by taking twice the length the box plus twice the height of the box, plus adding a small margin, such as 1/2 inch.
  • the width of the sheet is computed as the width of the box plus the height of the box plus a small margin, such as 1/2 inch.
  • drive means are provided for measuring out an appropriate length of paper from the roll and severing the tail when the predetermined amount has been withdrawn.
  • the slitters are represented at 70 in FIG. 1, and include a driven anvil roller 77 cooperating with a pair of slitter knife discs 70c, 70d.
  • a driven anvil roller 77 cooperating with a pair of slitter knife discs 70c, 70d.
  • the slitters 70 are positioned at either side of the machine, and are adjusted by a motor drive 70a and lead screw 70b.
  • the slitters are symmetrical with respect to the centerline of the machine, and operation of the motor 70a moves the slitters in unison either toward or away from the centerline.
  • the dimension between the slitters is adjusted to accommodate the computed width of the sheet needed for wrapping the package.
  • the drive for withdrawing the appropriate length of the sheet from the selected supply is associated with the paper feed 40, rather than the infeed stand 60. That allows a single drive to be utilized with all reels of paper in the infeed, and does away with the need for replicating a drive for each of the paper reels.
  • each paper roll can be provided with its own computer controlled drive.
  • a drive motor 73 preferably a stepping motor, operates through a drive belt arrangement 74 (see FIGS. 2 and 3) to drive input rollers 75, 76 which define the input end 67 of the paper feed 40. It will also be seen that the belt drives the anvil roller 77 of the slitter arrangement 70 and also drives an idler gear 78.
  • the idler gear 78 in turn meshes with a gear 79 m the selected nip pair 36, so that the motive force produced by the motor 73 drives the infeed roller 75, 76 at a given speed, and through the movable gear 78 also drives the nip rollers 36 at the same speed, to cause the paper to be withdrawn through the nip 36, past the slitters 70 and into the infeed pair 75, 76 of the paper feed 40.
  • the drive motor 73 is preferably a stepping motor drive supplied with drive pulses by a computerized control.
  • the computerized control having determined the length of the paper needed, outputs a number to a multiplexed drive, which drives the motor 73 with a calculated number of pulses, the number of pulses having been calculated to produce sufficient rotation of the motor to correspond to the desired length of paper.
  • substantially all of the drives are of the electronic stepping motor type to provide the precision of control which has been found to be desirable.
  • a turntable is described later in this specification, and the turntable can be operated with only three operative positions, the 0 degree position, the 90° position, and the 270° position. While it is preferred to use a stepper drive for the turntable, it may be possible to reduce expense by substituting an ordinary synchronous or induction motor with appropriate limit switches to control the three operative positions.
  • the gear 78 which is m a vertical plane oriented to mesh with gear 79 of the nip pair, but out of the plane of slitter roller 77, has two positions, controlled by an actuator 80.
  • a cam flat 81 is against an operating arm 82 of a linkage 83 for the gear 79 and the gears are unmeshed.
  • the actuator 80 is energized to transfer it to its alternate position shown in FIG. 3A.
  • the high point of cam 85 deflects the operating arm 82 to the left, causing the gear 78 to mesh with the gear 79 of the selected infeed rollers 36.
  • the belt drive in addition to driving the infeed rollers 75, 76 and the slitter roller 77, also drives the gear 79 which in turn drives the nip roll pair 36.
  • each nip pair may be desirable to dispense with the clutch mechanism for transferred motive power between the paper infeed and the reel stand, and to supply each nip pair with an individual electronically controlled drive.
  • one of the rollers of each nip pair such as the lower roller, is driven by a stepping motor, and the clutch mechanism is eliminated altogether. Synchronization between the paper supply and the paper infeed is electronically controlled.
  • a dashed box 79a is shown associated with the lower roller to substitute for gear 79.
  • the box 79a represents a drive motor, replacing the gear 79.
  • Such a drive motor will be associated with the lower roll of each nip pair 36-39 of FIG. 1, in this alternative.
  • paper is transferred from the nip rolls 36 over the slitter roll 77 into the nip between rollers 75, 76 to be carried upwardly by oppositely rotating belts 90 forming the sheet infeed 40.
  • the slitter discs Prior to initiating driving of the motor 73, the slitter discs were positioned laterally (by operating the drive of FIG. 4) to slit the respective edges of the paper to a predetermined width.
  • the paper is driven through the slitters which defines its width and carried into the paper infeed 40.
  • a knife apparatus generally indicated at 90 is triggered to sever the tail of the paper.
  • the lead edge of the paper is thereupon maintained between the nip rollers 36, while the drive 73 continues to rotate to bring the paper into a "ready" position in the belts 40.
  • FIG. 3A schematically illustrates elongated paper guides 67 (which span the width of the machine) , and are wide at the entrance and narrow at the exit.
  • the guides are adapted to guide the lead edge of the paper from its supporting point between the nip rolls 36, until the lead edge is again supported in the nip 75, 76.
  • the paper is adequate stiff to travel from nip to guide and guide to guide, to be reliably transferred into the belt drive 40. That is particularly true when the paper is being driven both by the nip rollers 36 at the output of the paper storage section, and then drawn into the sheet holder by means of input nips 75, 76 and a plurality of driven belts across the width of the machine.
  • the knife 90 has an elongated cutter bar 91 fixed in a guide 92 which allows the knife to move vertically in the guide.
  • a motor 93 drives a sprocket
  • a transverse traveling slitter arrangement can be provided.
  • the slitter has a knife which is displaced to contact with paper, whereupon the slitter is quickly traversed across the width of the web to sever the sheet.
  • the box can be positioned by hand on the table in any location between the input pusher 43 and the measuring station 42. It is not important that the box be manually centered, simply that it is placed in approximately the correct orientation, with the ends of the box which are intended to receive the flap oriented at about 90° to the centerline of the machine.
  • the measuring apparatus 42 has photoelectric measuring means 100 (see FIG. 6) positioned on an extended arm 101 of a carriage 102.
  • the carriage 102 in turn can be driven in a vertical direction by a drive generally indicated at 103.
  • the photoelectric measuring means 100 includes a light source mounted on one arm 101, and a receiver, such a phototransistor, mounted on the opposite arm 101 (see FIG. 7) .
  • the phototransistor thus produces a signal one level when the beam falls on the phototransistor, and at another level when the box interrupts the beam.
  • the photoelectric sensor associated with the arm 101, there are a pair of centering arms 107 fixed to ball nuts 106 driven by a lead screw 105 operated by motor drive 104. Operation of the motor drive 104 in a first direction moves the centering arms 107 toward the centerline of the machine, and in the other direction away from the centerline of the machine.
  • the pusher 43 is driven forwardly into the machine.
  • the mechanism for driving the pusher is a motor drive 110 (FIGS. 1 and 2) which drives a timing belt 112 (see FIG. 7) which in turn rotates lead screws 113 on either side of the machine.
  • the lead screws drive ball nuts 114 which carry the pusher 43.
  • energizing the motor 110 (FIG. 1) in a given direction drives the pusher 43 into the machine carrying the box with it.
  • the leading edge of the box will break the light beam between the measuring arms 101, signaling the controller that the lead edge has been detected.
  • the control circuit can compute the length of the box.
