Definitions

  • ABSTRACT Apparatus for opening and uncurling sheet or web material, and for guiding the material along a given path includes first and second pairs of rotatable seivage uncurlers arranged in serial order.
  • the uncurlers of each pair engage opposite edges of the material.
  • the lateral pull exerted by each uncurler is controlled by position sensors at either edge of the material. These are connected to react to an outward lateral shift of a first edge of the sheet by reducing the lateral pull applied to it by one of the first pair of uncurlers, and also by increasing the lateral pull on the other edge of the sheet by one of the second pair of uncurlers.
  • the apparatus guides the material with a quickly responsive continuous hunting action, while opening and uncurling the material into a flat form.
  • This uncurler comprises a pair of opposed disks having circular rows of teeth; the disks are mounted on relatively inclined rotational axes so that their teeth interengage one another through the edges of a travelling sheet or web. Uncurling is brought about by components of tooth motion which are lateral to the sheet and stroke the selvages out flat.
  • the apparatus guides the two edges of the sheet independently in predetermined tracks, and thereby not only uncurls and guides the sheet, but also tends to maintain a fixed sheet width.
  • l utilize first and second pairs of rotatable uncurlers, each of which is of such character that the lateral pull which it exerts on the material may be adjusted at will between two values, i.e. the degree of pull need not be a continuously variable function.
  • Control means respond to the sensors to adjust the relative degree of pull exerted by the uncurlers in such a manner that when one edge of the sheet wanders laterally outwardly, the lateral pull exerted by that one of the first pair of uncurlers which grips the outwardly shifted edge is temporarily reduced.
  • the lateral pull of that one of the second pair of uncurlers which grips the second edge is in creased.
  • the concurrent laterally inward shift of the second edge causes the pull of the remaining member of the first pair on that edge to attain its strongest value; it also causes the pull of the remaining member of the second pair on the first, outwardly shifted edge to decrease.
  • Rapid correction of the sheet deviation is attained because both uncurlers acting on the inwardly shifted second edge are exerting maximum pull, while both uncurlers acting on the first outwardly shifted edge are pulling at their feeblest. This results in a rapid movement of the entire sheet in opposite direction to the edge deviation that induced the control operation.
  • the mode of operation of the apparatus involves a continuous alternation of the net pulling efi'ort on the sheet, first in one lateral direction and then in the other.
  • the first pair of uncurlers are of the rotary disk type described by the aforementioned US. Pat. No. 3,419,944. These are driven by adjustable-speed motive means, and have the characteristic that the amount of lateral pull which they apply to the sheet is a function of their speed of rotation.
  • the second pair of uncurlers is preferably of a type known per se, each comprising a pair of rolls with helical surfaces, usually of a conical form. These rolls are not driven by motors, but are rotated by the longitudinal motion of the material, which is wrapped partially about their surfaces. These rolls are of such a character that they may be engaged or disengaged with the sheet to adjust the degree of lateral pull that they exert.
  • I provide a fluid control system which utilizes two air jet sensors for detecting the positions of the opposite edges of the sheet.
  • a first rotary disk uncurler acting on that edge is driven at a moderate rate of speed by an air motor supplied with air at a relatively low pressure, and so exerts its minimum traction.
  • That one of the helical roll uncurlers which acts on the opposite edge of the sheet is engaged with the sheet, and exerts its maximum lateral pull.
  • the remaining disk uncurler applies its maximum effort on the opposite edge while the remaining helical roll uncurler releases the first edge.
  • the net difference in lateral traction pulls the sheet quickly away from the direction of its original displacement.
  • the first-mentioned air jet which actuates a booster to increase the pressure of air supplied to the motor driving the first-mentioned disk uncurler.
  • the resulting increase in speed of this disk uncurler then generates its maximum lateral pull.
  • the booster supplies air pressure to disengage the first-mentioned helical roll uncurler from the opposite edge of the sheet. The remaining uncurlers are oppositely adjusted during these events.
  • the processing rate of sheet goods may be detrimentally affected by the occurrence of poor seams between successive lengths, or by width changes, which sometimes cause the goods to slip out of engagement with the uncurlers.
  • conventional installations of helical uncurler rolls it is necessary for the operator to first open or de-nip the rolls before he can reassert the material between them.
  • reinsertion after a slipout occurs is facilitated by the incorporation of a second set of sheet edge sensors. These are located laterally inwardly, with respect to the centerline of the sheet, from the sensors previously described. These sensors may also comprise air jets which are normally interrupted by the cloth.

  • FIG. 7 is a sectional end view taken along line 77 in FIG. 6, looking in the direction of the arrows.
  • a preferred embodiment of my invention incorporates a pair of rotary disk-type selvage uncurlers which are in themselves substantially as described in the aforementioned US. Pat. No. 3,324,525, but with the addition of variable speed motive means for driving them.
  • Each uncurler comprises a pair of disks l4 and 10, carrying circular rows of teeth 16 and I2, respectively.
  • the teeth are preferably formed of a flexible material such as rubber.
  • the disks are mounted with their rows of teeth in opposed relationship, each pair in a U-shaped bracket 36 having spherical clamps 32 and 28 at the ends of its opposed legs.
  • These clamps receive spherical bearing blocks 22 and 26, which are adjustable in the clamps to permit the axles l8 and 20 of the disks to be inclined as shown, so as to interengage the rows of teeth I2 and 16 over an arcuate sector.
  • the axles l8 and 20 are rotatably mounted in suitable bearings (not shown), which are in turn supported by the spherical clamps and bearing blocks for joint rotation of the disks.
  • each of these uncurlers is mounted in a desired relationship to a corresponding selvage of a sheet or web 5, by means of an enlarged plate portion 38 cast in the bracket and bolted to an arm 40.
  • Each of these arms is bolted at a pivot point 45 (FIG. I ⁇ to a clamp 42 mounted on a transverse bar 43 which forms a part of a stationary frame.
  • the disk uncurlers I0, 14 may be swung in or out laterally of the material by loosening the bolts at points 45, and are adjusted to suit the width of any particular material to be treated. Ordinarily, the centers of the disks should fall near the edges of the sheet 5.
  • the axles I8 and 20 of the disk uncurlers are tilted in the downstream direction of sheet travel, and laterally inwardly toward the center of the sheet, so that the teeth 12 and 16 interengage over a limited arcuate sector, usually extending from a point inside the location where the selvage first encounters the disks, around to a point near the place where the selvage departs from the disks. In the downstream portion of this are near the point of departure, the tooth motion has a large lateral component, and strokes the material laterally toward its edges.
  • the disks 14 are driven separately by a pair of air motors 42, and the rotation is imparted to the disks by the engagement ofthe teeth 12 and 16.
  • the sheet 5 After leaving the disk uncurlers, the sheet 5 passes through a pair of sensing heads 49, which are supported by arms 44 bolted to the brackets 36 at pivot points 51, so that the spacing between the sensing heads can be adjusted readily to suit the width of the material.
  • Each sensing head bears a pair of parallel bars 47 and 48, best shown in FIGS. 6 and 1.
  • the sheet 5 is threaded between these bars, slidably resting against them, so that it shields one from the other, as shown in FIG. 7.
  • the bars terminate in tapered tips 176 to avoid catching the material.
  • the head has a central bore for receiving a mounting bolt (not shown) to fix it in a suitable angular position with respect to the path of the sheet.
  • Air is supplied at a moderate pressure to each bar 48 by a conduit 76, a tee 142, and an elbow 148. Bores I44 and threadedly receive plugs I46 and I52, respectively, which are provided with jet-forming orifices 78 and 80. Separate air jets are directed by these orifices respectively toward receivers 82 and 84 formed in the bar 47. The entrances to the receivers are enlarged by forming arcuate slots 154 and 155 in the surface of bar 47. Plugs 158 and 159 are let into the receivers 82 and 84 to connect them respectively with signal pressure conduits 88 and 86, which are led out through the head 49 for use in controlling the operations of the apparatus.
  • Compressed air is also supplied to the receivers by a conduit 166 for the purpose of purging them of lint and dust, but its pressure is substantially reduced by a restrictor 164, so that it does not interfere with the development of usable signal pres sures.
  • This purge air is delivered to the receiver 82 by a tee and an orifice plug 162, and to the receiver 84 by a tube 168, elbow 170, and orifice plug 172.
  • a second pair of uncurlers each comprising helical rolls 54, 56 engages the selvages of the sheet after it leaves the sensing heads 49.
  • These rolls have helically grooved conical surfaces partially wrapped by the sheet, which is threaded between them.
  • the feeding of the sheet causes them to rotate and to stroke the edges of the material outwardly.
  • the degree of lateral pull which they exert depends upon the pitch of the helical grooves, and also upon the extent of their engagement with the material.
  • each helical roll uncurler is rotatably supported in an arm 55, carrying a shaft which supports the roll 56 on bearings 182, and a shaft 184 which supports the roll 54 on similar bearings (not shown).
  • the shafts I80 and I84 are preferably inclined to one another as shown, causing the rolls 54 and S6 to converge toward their tips.
  • the arm 55 is pivotally mounted on a base 52 by means of a shaft 186, fixed to the arm and received in bearings 188, so that the roll 54 is movable between a position engaging the material, shown in solid lines in FIG. 2, and a disengaged position shown in dotted lines at 54'.
  • the uncurler is in the latter position, the roll 56 still engages the sheet, but the contact is too light to exert substantial lateral pull on the selvage.
  • the arm 55 is biased in a direction to engage the rolls with the sheet by means of a coil spring 190, of which one end is engaged in a slot 196 of the shaft 186, and the remaining end is fixed by a rivet 194 to a housing 192 pinned to the base 52.
  • the assembly is enclosed by a cap 198.
  • the roll 54 is disengageable from the sheet by supplying air pressure to an actuating cylinder 58, whose piston 65 is pivotally connected at 201 to the arm 55.
  • a return spring 64 aids the spring I90 in restoring the piston and arm to the position of FIG. 4 when the air pressure is released.
  • the cylinder 58 is pinned at 202 to a bracket 204, which is secured by a bolt 206 to a transverse boss 53 formed in the base 52.
  • the bosses 53 of the two helical uncurler units also serve to mount them on arms 50 which are bolted to the brackets 42 at pivot points 41 so that the spacing between the uncurlers may be adjusted readily to suit any particular sheet width.
  • the disk uncurlers 14, the sensing heads 49, and the helical uncurlers $4, 56 are shown connected into a pneumatic control system. Compressed air is supplied from any suitable source (not shown) to a filter 66. Pressure for operating the uncurlers is taken through a pressure-regulating valve 104 and an oiler 106 to a supply conduit 102 having a gage 108, and is delivered by branches to left and right adjustable needle valves 110 and 112, as well as to left and right booster relay valves 98 and 100.
  • booster valves are of a type which is normally closed, and either may be opened by applying a signal pressure through a corresponding control conduit 94 or 96. Opening the left booster 98 admits air at full pressure to a conduit 134 for actuating the right-hand air cylinder 58, to disengage the corresponding helical rolls 54, 56 from the sheet; at the same time, full pressure is supplied to the motor 42 of the lefi-hand disk uncurler through a branch conduit 122 having a check valve 1 l4, and a conduit 128 equipped with a gage 132.
  • Opening of the right booster 100 similarly supplies full pressure through a conduit 136 to disengage the left-hand helical uncurlers 54, 56, and through a branch conduit 124, check valve 116, and a conduit 126 equipped with a gage 130, to the motor 42 of the right-hand disk uncurler 14.
  • booster relay valve 98 or 100 When either booster relay valve 98 or 100 is permitted to close, air under a pressure reduced by the needle valves 1 or 112 is furnished by conduits 1 l8 and 128, or 120 and I26, to the corresponding air motor 14, driving the connected disk uncurler at a reduced speed, so that the lateral pull which is exerts on the sheet is correspondingly decreased.
  • the supply of pressure to the actuator 58 at the opposite edge of the sheet is then cut off by the presence of the corresponding check valve 114 or 116, so that the opposite helical roll uncurler 54, 56 engages the material and exerts its normal pull.
  • air pressure is supplied to the jets 78 and 80 of the sensing heads 49 by a regulating valve 68, a supply conduit 72 having a gage 70, and the branch conduits 76 previously described.
  • the spacing between the heads 49 is adjusted so that the sheet just spans the distance between the outer receivers 82 of the two heads, one selvage lying over each receiver.
  • the sheet is then fed forwardly as previously explained. As the sheet wanders to left or right, it uncovers one of the receivers 82, and the associated jet 78 delivers a pressure signal to the corresponding one of the two signal conduits 88.
  • a pressure signal at the left receiver 82 brought about by a shift of the material to the right, is delivered by a conduit 94 to open the booster 98.
  • This increases the speed of the left disk uncurler l4, enhancing its leftward pull on the material, while disengaging the right helical roll uncurler $4, 56 to discontinue its rightward pull.
  • the left helical roll uncurler maintains engagement and full pulling effort, while the right disk uncurler rotates at the lesser of its two speeds and exerts relatively little effort on the goods.
  • both of the left-hand uncurlers pull their best, while both right-hand uncurlers relax their efforts joindy. The result is a rapid shift of the material to the left, and this very quickly corrects the rightward lateral deviation.
  • the correction covers the lefthand receiver 82 and closes the booster 98, which lowers the speed of the left disk uncurler 14 while re-engaging the right helical roll uncurler 54, 56.
  • the corrective movement is, however, quickly followed by an exposure of the right-hand receiver 82 as the cooperating selvage is shifted away.
  • the resulting pressure signal opens the booster valve 100, and produces increased pulling effort by the right disk uncurler, while disengaging the left helical roll uncurler.
  • the control action is cyclically repeated, and causes the sheet to be guided within limits of lateral deviation that are determined by the effective widths of the air jets 78. Lateral shifts of the goods are corrected with great rapidity, so that the permitted limits of lateral deviation are asserted with little latitude.
  • the laterally inner jets 80 and receivers 84 cooperate to supply pressure signals through their signal conduits 86, each of which is cross-connected to the booster 98 or 100 which is normally controlled by an outer receiver 82 located at the opposite edge of the goods. This causes the helical roll uncurler 54, 56 at the edge that has slipped out of the uncurlers to disengage from the sheet.
  • both helical roll uncurlers are automatically opened when a slip-out occurs, and the operator can easily reinsert the material and re-start the sheet-feeding apparatus with a minimum of effort and delay.
