Definitions

  • the invention relates to a method for the pneumatic handling of wafer sheets, wherein a vacuum is generated between a wafer sheet and an end face of the holding plate facing the wafer sheet.
  • wafer sheets have to be handled in a variety of ways after the baking process and up to the production of coated or filled waffles.
  • the wafer sheets have to be lifted and put down, turned, swiveled, stacked and unstacked.
  • vacuum suction devices have been used in the past instead of mechanical gripping devices, in which the waffle sheets are sucked and held by a suction process on the end face of a holding plate, whereupon the holding plate in each required way is moved, for example raised and / or pivoted.
  • suction channels open in the end face of the holding plate and are connected to a vacuum source.
  • Loose waffle particles and cream residue can be sucked in during the suction process. This can lead to pollution or even Block the suction channels or other connected vacuum lines.
  • the object of the invention is therefore to provide a method of the type mentioned, in which there is no risk of clogging or contamination of the connected lines.
  • This object is achieved in that a surface-parallel air flow is generated between the end face and the wafer sheet.
  • This surface-parallel air flow creates a negative pressure between the wafer sheet and the end face facing it, through which the wafer sheet is sucked in the direction of the end face. Nevertheless, no air is sucked into channels, so that no contaminants can be sucked in.
  • the air flowing between the wafer sheet and the face exits into the environment at the edge of the wafer sheet. Impurities entrained by the air flow precipitate as a result of the slowing down of the emerging air flow or can be caused by conventional ones Extraction hoods are collected. There is no risk of contamination or clogging of lines, suction boxes or filters.
  • the air flow parallel to the surface is preferably generated by supplying compressed air in a central region of the end face and outlet in the edge region of the end face.
  • the invention also relates to an apparatus for performing the method.
  • a device with a movable holding plate which forms the end face into which at least one air duct opens
  • the air duct is connected to a compressed air source, for example also a blower, and that a baffle plate parallel and in front of the mouth of the air duct is arranged at a distance from the end face, an air outlet gap being formed between the deflection plate and the end face.
  • the deflection plate can be arranged at a fixed distance or at an adjustable distance from the end face. Instead, it is also possible to guide the deflecting plate so that it can move in parallel with respect to the end face, so that it automatically adjusts to a favorable distance under the effect of the emerging air flow.
  • FIG. 1 shows a section through a holding plate of a device for the pneumatic handling of wafer sheets
  • FIGS. 1 and 3 a further modified embodiment of a holding plate for handling waffle sheets
  • FIG. 6 is an enlarged detail at VI in Fig. 5, Fig. 7 in a section corresponding to FIGS. 1, 3 and 5, a holding plate for handling profiled wafer sheets and
  • FIG. 1 shows a holding plate 1, which forms a movable part of a device (not shown) for handling waffle sheets 2.
  • the holding plate 1 has a connecting piece 3, through which an air duct 4 extends, which is connected to a compressed air source 5, which is only schematically indicated in FIG. 1.
  • the air channel 4 opens into the central region of the holding plate 1, which has an end face 6 facing the wafer sheet 2.
  • a deflection plate 8 is arranged parallel and at a distance from the end face 6.
  • An air outlet gap 9 is formed between the deflection plate 8 and the end face 6, through which an air flow emerges parallel to the end face 6 on all sides.
  • the deflection plate 8 is connected on its rear side to a guide pin 10 which is received in the air duct 4 with lateral play.
  • a threaded section 11 at the opposite end of the guide pin 10 is screwed into an internal thread of the connecting piece 3 and carries a lock nut 12. This limits the axial position of the guide pin 10 and thus the width of the air outlet gap 9.
  • the surface-parallel air flow between the end face 6 of the holding plate 1 and the waffle sheet 2 creates a negative pressure in the gap between the end face 6 and the waffle sheet 2, through which the waffle sheet 2 is sucked in the direction of the end face 6 or is pressed by the ambient pressure, as in FIG 1 is indicated by arrows 13.
  • the parallel air flow emerges at the edge of the holding plate 1, as indicated by arrows 14.
  • the wafer sheet 2 thus held in its position in front of the end face 6 can be handled in the required manner by lifting, pivoting or other movement of the holding plate 1, for example being lifted and stacked. In order to detach the wafer sheet 2 from the holding plate 1, it is sufficient to interrupt the compressed air supply from the compressed air source 5.
  • the modified embodiment shown in FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 essentially in that the deflection plate 8 is fastened on its rear side via individual spacers 15 at a fixed distance in front of the end face 6. At the edge of the end face 6 of the guide plate 1, lateral guide stops 16 are attached, which hold the edge of the wafer sheet 2 against lateral displacement.
  • the embodiment according to FIGS. 5 and 6 differs from the previously described embodiments essentially in that the deflection plate 8 arranged in front of the mouth 7 of the air duct 4 is opposite the End face 6 is movable in parallel.
  • the deflection plate 8 is therefore arranged to be floating to a limited extent.
  • the guide pin 10 attached to the rear side of the deflection plate 8 here carries at its free end a stop ring 17 which strikes a shoulder 18 of the air duct 4 and thus limits the movement of the deflection plate 8 perpendicular to the end face 6.
  • the deflection plate 8 ' is provided on its outside facing the wafer sheet 2' with a centering projection 19 which engages in a recess 20 in the wafer sheet 2 'and thereby the wafer sheet 2' in its Centered in front of the end face 6.
  • the air outlet gap 9 1 here consists of air slots which are adapted in shape and position to the wafer sheet 2 'to be held.
  • the waffle sheet 2 has bulges 21 which face the end face 6 and bear against it.
  • the air flow parallel to the surface flows between these bulges 21 and, in the manner already described, also generates a negative pressure here, which holds the wafer sheet 2 ′ on the holding plate 1.

Abstract

L'invention concerne la manipulation pneumatique de feuilles gaufrées (2). Pour ce faire, une plaque de maintien (1) placée en amont de l'orifice (7) d'un canal d'air (4) qui est relié à une source d'air comprimé (5), présente une plaque de renversement (8). Entre une face frontale (6) de la plaque de maintien (1) et la feuille gaufrée (2), on produit un courant d'air qui est parallèle aux surfaces et provoque une pression négative qui maintient la feuille gaufrée (2) plaquée contre la plaque de maintien (1).
