Abstract

The invention concerns an apparatus for forward transferring sheet-like objects from a stack, said apparatus including separate lifting elements gripping by suction to the upper surface of the sheet-like object situated top-most on the stack. The gripping elements are positioned in a row extending over the stack of the sheet-like objects in transversal direction with respect to the forward direction of the sheet-like object. The suction effect of the lifting elements is individually controlled by means of a control device including a light source creating a substantially line-shaped illumination pattern over the top of the stack. The illumination of the light source is focused substantially parallel to the lifting element row, at an inclined angle to the surface plane of the sheet stack. Camera means for observing the illumination pattern forwards information about the uniformity of the uppermost layer of the stack for controlling the gripping elements.

Description

  • The present invention concerns an apparatus for transferring sheet-like objects from a stack formed thereof. Especially the invention concerns an apparatus for transferring veneer sheets and the like.
  • Equipment based on suction gripping devices is used for this purpose, for gripping the upper surface of the uppermost veneer sheet in the stack and lifting the sheet into contact with transferring devices. The transferring devices are usually horizontal rolls cooperating with the suction gripping devices, having rotating motion parallel to the intended transfer direction. The sheets to be transferred are lifted one by one with the suction gripping devices into contact with the mantle surface of the rolls, and kept in contact with the mantle surface of the rolls for providing the transferring event.
  • The suction gripping devices are in principle single suction nozzles arranged in a row extending substantially over the stack in transversal direction with respect to the intended transfer direction. The device operates without problems with full-sized veneer sheets, but problems are caused by random veneer layers consisting of narrower sheets than the sheets with full width.
  • It has been tried to compile these random sheet layers so, that the random width sheets are side by side in the layer and cover substantially the same area in the stack as the sheet with full width. At this kind of a stack layer, the transferring device known in the art in general still operates without problems, in other words, the suction gripping devices get a grip on all sheets of the uppermost layer, and they are moved together from the stack forward, usually to the drying apparatus of veneer.
  • In spite of careful compiling of the layers in the stack, whether made manually or by machine, there are mistakes occurring when compiling the layers, as a result of which there can be sheets in a layer more or less overlapping each other Overlapping sheets are also forwarded, when uppermost on the stack, supported by the suction gripping devices, at least partly overlapping. A part of the sheets taken along with the suction gripping devices may loosen too early, and fall back onto the stack, as a result of which the top layer of the stack will be mixed. Due to the overlapping, the veneer sheets that hold on cause problems for the apparatus handling the veneers in the next step, like in the drier, as blockages that are difficult to unblock, incomplete drying etc.
  • A single random veneer left or fallen in the stack follows on top of the next full veneer in the next lifting step causing the overlapping problem.
  • With the apparatus of the present invention, these problems have been significantly solved.
  • The basic structure of the apparatus according to the invention is formed by an apparatus comprising, as known in the art, separate lifting elements gripping by suction to the upper surface of the sheet-like object to be transferred, said lifting elements being located in a row extending over the stack of the sheet-like objects, in transversal direction with respect to the transfer direction of the object, and transfer means for transferring the lifted sheet-like object. According to a characteristic of the invention, the suction effect of the lifting elements can be individually controlled by means of a control device including a light source creating a substantially line-formed illumination pattern, the illumination being focused substantially parallel with the lifting element row, at an inclined angle in respect to the plane of the surface of the sheet stack, and a camera means for observing the illumination pattern.
  • The invention will be described in more detail in the following with reference to the enclosed drawing, wherein
  • FIG. 1 shows the apparatus according to the invention for transferring veneer sheets from a stack,
  • FIG. 2 shows the apparatus of the invention at the operating stage, and
  • FIG. 3 illustrates the effect of the control of suction lifting devices on the operation of the device.
    •
  • FIG. 1 shows schematically a veneer stack 10, where veneer sheets are being removed from, layer by layer, to be forwarded to further processing, like drier. The veneer layer is lifted from the stack by means of suction lifting devices 8 operative in the vicinity of the upper surface of the veneers. When the suction effect 4 is active, the suction lifting devices grip the veneer or veneers of the uppermost veneer layer and bring them into contact with the rolls 14, keeping the lifted veneer or veneers in contact with the rolls. The rolls have rotational motion in the transfer direction, and they take the veneer or veneers in the intended transfer direction, for example to be transferred by the rolls 5. FIG. 1 shows a typical problem situation that can occur in the stack 10 in cases, where there is a layer composed of random width veneer sheets. The veneer sheets are partly overlapping. Thus, an apparatus having the construction of prior art would probably face an operating disturbance.
  • To avoid the operating disturbance, the basic apparatus is complemented with an additional device according to the present invention, by means of which the operation of the suction lifting devices can be controlled in an appropriate way.
  • Each of the suction lifting devices 8 is equipped with respective closing means that in the described embodiment is formed by a slide 7 and an actuator 6, like a pneumatic cylinder-piston device. With the closing means, each suction lifting device can be connected to or disconnected from the suction effect 4. Individual operation of the actuators is controlled by an activating device being able to make logical decisions based on the received information. The activating device is not shown in the figure. This kind of a device is well known to a person skilled in the art, and there is no need to describe its operation in detail in this connection. The activating device receives the required information from the camera means 1 included in the apparatus. The camera means is a matrix camera known in the art, having a suitable resolution for the task. The visibility range of the camera reaches over the veneer stack, and is in the perpendicular direction wide enough to observe the illumination pattern focused onto the surface of the veneer stack.
  • The illumination pattern is focused onto the surface of the veneer stack line-shaped, with a strong light source 2, suitable for this purpose being a laser light source. The illumination is focused onto the surface of the stack at an inclined angle of 20° to 45°, for example. If there happens to be veneer sheets positioned overlapping on the surface of the stack, the beam of light first meets the sheets locating highest on the stack, like sheets 11 and 12 in FIG. 1. The sheets locating lower get to the beam of light at a longer distance from the light source 2, whereby the illumination pattern formed onto the surface of the stack is correspondingly stepped. This stepness will be discovered by the camera 2. It gives information on the location of the steps of the illumination pattern in the transfer direction of the veneer sheets, and the extension of each step in the direction of the illumination pattern. Based on this information, the activation device of the suction lifting devices makes logical decisions, which of the veneer sheets (11 and 12) is/are uppermost in the stack, and what is their location in the stack, in the transversal direction with respect to the transfer direction. Based on these decisions, the activating device controls the closing means 8 to open only at the veneer sheets lying uppermost in the stack, whereby only those are taken to be transferred with the rolls 14 and are removed from the stack, FIG. 2.
  • The capacity of the apparatus further processing the veneers will be underutilized per each such lifting turn, but there will be no overlapping veneer sheets in the apparatus, and no veneer sheets drop back on top of the veneer stack. Correspondingly, the problems being caused by the sources in question will be avoided in the operation of the apparatus.
