Definitions

  • FIG. 1 LABEL INSPECTION SLITTER/REWINDER Filed Feb. 8, 1972 .3 Sheets-Sheet l FIG. 1
  • the unwinding web is made to follow a path which brings it sequentially to a web inspection location and a splicing location.
  • Braking means are provided for halting the movement of the web along the path.
  • the distance along the path between the web inspection location and the splicing location is long enough to permit the braking means to halt the movement of the web before a given point on the web can move the full distance from the web inspection location to the splicing location. In this way, there is no need to provide reverse drive facility on the unwinding mandrel for the purpose of moving the web backwards should a faulty section detected at the inspection location over-shoot the splicing location.
  • This invention relates generally to web-processing apparatus, of the kind adapted to perform certain operations on a roll of web unreeling from a mandrel. More particularly this invention relates to web-processing apparatus in which the web may be continuously inspected for faults, and in which any faults can be spliced out at a splicing location.
  • the label manufacturer has only an approximate idea of the total number of labels in one of his large-diameter rolls, it is sometimes desirable to rewind the web so that a more accurate count can be made.
  • the rolls of labels are purchased on condition that the stated number of labels in each roll be exactly correct. This latter situation arises, for example, where a pharmaceutical company is bottling medicine.
  • the bottling, labelling and sealing apparatus in the pharmaceutical bottling plant is such that it must be fed with a controlled number of bottles,
  • a digital counter is provided in conventional machines.
  • this invention provides a web-processing device, comprising: an unwinding mandrel adapted to unwind a roll of web, a rewinding mandrel, means adapted to guide a web along a path from said unwinding mandrel to said rewinding mandrel, braking means for halting the movement of the web along said path, a web inspection location in said path, and a splicing location in said path between said web inspection location and said rewinding mandrel.
  • the distance between the web inspection location and the splicing location is at least as long as the maximum length of web to be unreeled from the roll during the operation of the means for halting the movement of the web, whereby the web defects detected at the inspection station can be arrested upstream of the splicing location through the action of said means.
  • FIG. 1 is a perspective view of an apparatus for processing a roll of web, embodying this invention
  • FIG. 2 is a schematic illustration of the components of an apparatus embodying the invention
  • FIGS. 3 and 4 are elevational views of a web illustrating the way in which reverse web movement can lead to erroneous digital counting.
  • FIG. 1 shows a web-processing apparatus which includes a main frame and housing 12 steadied by two leg braces 14.
  • An unwinding mandrel )16 extends horizontally outwardly from the housing 12 in the lower portion thereof.
  • the unwinding mandrel 16 is preferably of the conventional expanding type, and is adapted to receive and grip a roll 18 of web 19.
  • the web 19 then passes obliquely downwardly and is entrained around a third idler roller 25, from which it passes to a fourth idler roller 26, and thence to edge guide roller 28 which is provided with two flanges 29 between which the web 19 can be entrained.
  • the edge guide roller 28 is supported at the left end of the brace element 24. After the edge guide roller 28, the web 19 passes rightwardly to a fifth idler roller 30, from which it enters the nip between a draw roll 32 and a nip roll (not shown in FIG. 1 but visible at 33 in FIG. 2).
  • the web 19 After passing between the draw roll 32 and the nip roll 33, the web 19 passes between a pair of rotary shearcut slitters 35, thence around a sixth idler roller 36, and finally around a rewinding mandrel 38.
  • a uni-directional digital counter 40 is provided atop the housing 12, but may be incorporated into the housing if desired.
  • the sensing head which controls the counter is located within an auxiliary housing 42, but may be located at any position between the fifth idler roller 30 and the rewinding mandrel 38.
  • a conventional control panel 44 is also mounted on the housing 12, but need not be described in detail here.
  • a web inspection location at which the moving web 19 can be examined either by an operator who simply monitors the web 19 as it passes, or by automatic or semi-automatic web-inspection means, of conventional nature, using for example a stroboscopic device 48.
  • an ordinary electric lamp 50 is also provided at the web inspection location 46.
  • the splicing location 52 includes two bar clamps 54 of conventional construction. At the splicing location 52, the web 19 is adapted to pass over the surface of a horizontal table 55 supported by the brace element 24, and against which the bar clamps 54 are adapted to clamp the web 19. In order to remove a section of defective web, the web is first clamped using the right clamp 54, and then cut laterally with a knife (not shown) which is guided in a splice guide tract (not shown). The defective web is then pulled forward until the section of defective material has gone past the edge already cut. Then, the lateral edges of the two pieces of web are lined up and the upstream section of web is locked with the left clamp 54.
  • the knife is then again used to cut the upstream section of web in the same splice guide track, and the two pieces of web are then spliced together using tape (not shown).
  • the foregoing splicing procedure is conventional, as are the different devices used to carry it out, and none of these need to be described in detail in this disclosure.
  • the preferred embodiment of this invention contemplates that the distance along the web between the web inspection location 46 and the splicing location 52 be at least as long as the maximum length of web unreeling from the roll 18 during the operation of the braking means to halt the movement of the web. This gives an operator sufficient time, after he detects a fault in the web, to bring the web to a stand-still before the fault reaches the splicing location. This means that the operator is not required to reverse the machine to retrieve defective web from the rewinding mandrel or from a location downstream of the splicing station. This means that slit side-register problems caused by reversing are avoided. It also obviates the need for a bi-directional counter and totally eliminates the risk of erroneous digital counting which arises whenever re verse web movement is utilised.
  • FIG. 3 the web 19 is shown in elevation so that it appears in edge view.
  • the web 19 includes a liner 57 which has adhered to its upper surface a plurality of sequential labels A, B, C, D, etc.
  • Two components of the counting head are shown in FIG. 3, the first being a light source 56 adapted to throw a parallel pencil of light downwardly at right angles to the web 19, the second being a photo electric cell 58 placed beneath the web 19 directly in the path of the pencil of light being emitted from the light source 56.
  • the liner '57 is relatively transparent to the light being emitted from the light source 56, while the labels A, B, C, D, etc. are relatively opaque. It will be noticed that the labels A, B, C, etc.
  • the digital counter is set so that it counts one" each time the light level received by the photoelectric cell '58 passes from high to low (or light to dark). If we assume that the web 19 is moving to the right, then the last added unit in the digital counter will have taken place when the leading edge 60 of label B passed across the pencil of light from the source 56. The unit prior to that was added when the leading edge 62 of label C cut through the pencil of light, and so forth. The digital counter ignores the change from low level to high level as the trailing edge of each label passes between the light source 56 and the photoelectric cell 58.
  • the digital counter is instructed to subtract one unit from the total each time the protoelectric cell 58 passes from high level to low level.
  • the web moves left-wardly a distance equal to twice the width of a label, and comes to a halt with the label D situated between the light source 56 and the photoelectric cell 58.
  • the digital counter would have subtracted one as the leftward edge 64 of the label C passed across the pencil of light, and would have subtracted one more as the leftward edge 66 of the label D passed across the pencil of light, taking the total down to 1002.
  • forward motion to the right
  • the digital counter would correctl register label C at 1003, label B as 1004, label A as 1005, etc. In the case just described, therefore, no error in the digital counting would result.
  • Passing the unreeling web along a path which encircles the roll 18 is one way of ensuring a sufficient length of web between the web inspection location 46 and the splicing location 52 to permit the braking means 68 (shown in broken lines in FIG. 2) to halt the rotation of the roll 18 before the detected faulty section of the web 19 reaches the splicing location 52. After the initial halt, the web is then moved forward slowly (not backward) until it reaches the splicing station 52.
  • braking means 68 could be replaced by some other web-halting means not necessarily acting on the unwinding mandrel 16.
  • a web-processing device comprising:
  • the distance along the web between the web inspection location and the splicing location being at least as long as the maximum length of web unreeling from said roll during the operation of said means to halt the movement of said web, whereby a web fault detected at said inspection location can be arrested upstream of the splicing location through the action of said means.
  • the invention claimed in claim 1, which further includes a nip-roller station in said path between the splicing location and the rewinding mandrel, the web undergoing a change in tension at said nip-roller station, said path encircling the unwinding mandrel and being spaced sufiiciently far therefrom to avoid contact with a roll of web mounted thereon, the web-processing device further including uni-directional counting means adapted to count sequential discrete laminar elements of the web.
  • a method of processing a roll of web comprising:
