Definitions

  • the invention relates to an apparatus able to provide tape sections of paper or other material for wrapping or other uses, of predetermined size, which apparatus is particularly suitable for public and commercial business for the retail sale of foodstuff especially non pre-packaged, and for crêpe papers for sanitary or industrial uses; it is particularly suitable for the unwinding of paper or other thin material, as imposed by recent rules to avoid the wrapping tare in the weight of the product on sale.
  • the feeding apparatus comprises in combination: a support for a reservoir-reel from which the tape may be unwound by pulling action; a pair of motor driven rollers for the controlled unwinding; control means for the pair.of rollers for a predetermined and limited advancement of the tape; a cutting means for the tape, operated after the rollers advancement and stopping, to perform the cut; and a pressure means, downstream of the cutting means, which is operated to act upon the tape in order to help the cut.
  • a means may be provided to achieve a slight restraint of the separated sheet, in order to allow its drawing but not its spontaneous moving away. The restraint effect must cease at the moment the rollers advancement is operated.
  • the driving means may be controlled by a mark reader.
  • the feeder may include a reader which detects the moving away of a piece of cut paper, and which thus causes the control of the rollers advancement.
  • a single reader, photocell or the like may be arranged to cause the advancement starting in the absence of a piece taken away, and the stop in the presence of a mark.
  • a reel of thin papery material (or other equivalent) from which the tape - of paper or other - must be unwound to delivery sections of predetermined length for the use.
  • the unwinding is operated through a motorized drive by a pair of unwinding rollers 3 and by a further pair of unwinding and pressure rollers 5; the latter rollers 5 are driven through a unidirectional, that is, free-wheel joint, which allows a faster rollers rotation than the one caused by the motorized drive, which faster rotation serves to have the material located between said rollers 5 taken away when withdrawn from the outside by a pull of even limited value.
  • a cutter 7 is located, schematically represented, with a contrast part 7A for a blade 7B (but that can be made in any other suitable and known manner) for separating single sections of papery material or other indicated by C and for drawing the unit length so defined.
  • a contrast part 7A for a blade 7B (but that can be made in any other suitable and known manner) for separating single sections of papery material or other indicated by C and for drawing the unit length so defined.
  • the cut achieved by the shearing device 7 will cause the separation of the section to be delivered, which remains retained between the standstill pressure and unwinding rollers 5, until a pull is exerted according to arrow f T ; by this pulling action the cut sheet, that is the section of desired unit length, is taken away, by a rollers 5 rotation allowed by the free-wheel joint.
  • a reader and control device for stopping the motor driven rotation of the pairs of rollers 3 and 5; this device may be of photocell type aranged to cooperate with a printed mark, but it may be also of other type, for example, of electrical switch type cooperating with slots, or of magnetic type cooperating with magnetic inks or other.
  • the device 9 determines the stopping of the tape unwinding to achieve the cutting and drawing of sections of predetermined length. In Fig. 1 this device is located upstream of the cutter as well as of the rollers 3.
  • a feeler means 10 Downstream of the cutter 7 and, in particular, but not necessarily, downstream also of rollers 5, a feeler means 10 is provided - of mechanic type, photocell or other - which is able to detect the presence or the lack of paper in correspondence of the sight that it represents.
  • This feeler means 10 is set to provoke the rotation start of the pairs of rollers 3 and 5 when it detects the absence of papery material on the sight and so when a section C1 of unit length, delimited by the cut operated by the cutter 7, 7A, 7B, has been drawn.
  • the cutter is operated to perform the cut the moment the rollers 3 and 5 stop, mostly through the control of the reading device 9.
  • a single reader and feeler device 19 (instead of members 9 and 10) located between the cutter 7 and the free-wheel rollers 5, this device being able to perform both the function of the mark reader 9 and that of the feeler means 10.
  • a mark may be read even in a position in which the device 19 is located, and the latter may also detect the lack of papery material when the section C1 is withdrawn.
  • the described delivery apparatus - when used for wrapping material - may be arranged on a sale bench or behind a sale bench, with a horizontal or vertical orientation and with the section prepared for the withdrawing which may be partly or fully sheathed for sanitary or protection purposes particularly in case of installation in restricted space.
  • the apparatus may be also used for other purposes - as already mentioned - that is, for towels, toilet paper and other.
  • Fig. 3 there are still provided members 1, 3, 7, 7B, 7A and 19 whose funtions are analogous to the ones described above.
  • the rollers 5 are replaced by a presser 55, mostly resilient, which upon the cut by the blade, produces a strong action on the tape C for a good cut execution.
  • a presser 55 mostly resilient, which upon the cut by the blade, produces a strong action on the tape C for a good cut execution.
  • a specific presser 255 having a slight restraint action.
  • the presser 255 or anything else providing analogous function must be lifted to allow the free advancement of the material when rollers 3 are running.
  • the rollers 5 may be non-motorized but simply developed for a unidirectional rotation. In this case they may perform a restraint action to ensure the regular cutting operation retaining the paper - when the blade is in action - together with the rollers 3 which, in this occasion, may be temporarily forced one against the other. Since they can rotate in the moving away direction of section C1, they permit such removal but have also a restraint effect against a spontaneous moving away. When the rollers 3 cause the material C to advance, the rollers 5 must be separated to allow this advancement.
  • the drawing shows an exemplification given only as a practical demonstrat ion of the invention, since the invention may vary in the forms and dispositions without, nevertheless, departing from the ambit of the idea on which the invention is based. It is not excluded, for example, that the apparatus might be completed with a selector capable of quickly presetting different lengths of material to be delivered, by arranging the selector in two or more positions and by presetting groups of different marks or of differently aligned marks with different readers located in position or with a reader differently positioned from the commutation means.
  • This apparatus does not require any pre-cut ting operation and thus the lengths are definable only by the reading mark and by the print which may be centered or replaced by a watermark, but which may also be continuous.
  • provision may be made so that a single reader should control the unwinding start, and that the rollers rotation be limited in order to achieve the stop after a determined length of unwound tape.
  • the possibilities provided by the feeder are such that the material can be reeled - upstream - without pre-cutting operation and then with much higher productivity.
