Description

FIELD OF THE INVENTION The invention relates to a flat material handling apparatus comprising a support frame having at least one suction frame having a support surface having underpressure suction heads for receiving flat materials by suction.

Such processing devices are generally known, especially for glass panes.

10

They are often used to place glass panes from the storage or transport rack to the reception desk or to take them off the table and transfer them to the rack. Such devices are called portal stackers or feeders, depending on the direction of transport.

One such device is known, for example, from DE 298 21 526 UI, which discloses a linear-acting fluid-pressure-driven unit having two telescopically internally movable guide tubes, the second guide tube having a fastening device for, for example, a support frame for taking glass panes by suction heads.

20 Such devices are, moreover, known from other sources for which there are no written publications available. The invention will be explained in the following with respect to the case · · · ·:. however, without limiting the invention.

• · m • · · 25 • · · · · ·

The problem with all flat materials, especially glass sheets, is that they use different, often even standardized, sizes, so-called ribbon. . *. sticks and split tape sizes that vary in size. In the case of glass sheets »··. ·· *. such processing equipment must handle coated and uncoated glass.

However, the coated glasses must, for example, be placed on the receiving table with the coated side facing up so that the receiving table does not damage the coating. On the other hand, in the case of uncoated glasses, the receiving table is placed on the receiving side without the suction means attached. It is considerably simpler to achieve such a setting movement.

2 119053

It is thus an object of the invention to provide a processing device for flat materials which can alternatively handle different sizes as well as, for example, coated or uncoated flat materials, and which is further implemented in the simplest possible construction.

This object is solved in accordance with the invention by a flat material handling device of the type disclosed in the preamble, wherein the carrier frame can pivot between a substantially vertical position and a substantially horizontal position, wherein the carrier surface can be pivotable horizontally As a result, coated and uncoated flat materials can be transferred with the same processing device. Coated materials, such as laminated safety glass panes, can be placed horizontally so that the suction heads and the flat material adhered thereto are directed upwardly and the suction heads pass through the receiving table so that the coated side, which is not gripped by the suction heads, does not . Alternatively, uncoated glass sheets can be grasped and the surface of the glass sheets on which the suction heads are not attached can be placed, for example, on a horizontal support table. In addition, it is also possible to perform a reverse treatment, i.e., from a horizontal support table to a rack in which the flat materials are placed vertically. Vertical here also refers to a slightly *: * non-vertical position which is commonly used to make a flat material ·· »· stand and reliably lean on e.g. a rack. This cul-! the vertical deviation of the map can usually be up to 10 °, which is the angle of the rack and thus: the flat materials are inclined. This area is also considered to include: 25 concepts vertical.

The support table can then be both a belt and roll conveyor table or arrangements where:. · *: Both are combined.

• · * * • m • · * · ·. ···. The invention further enables the suction frame with its supporting surfaces to be visible to it * · ·. * ··. pivoting about a perpendicular axis. This reversibility provides the advantage that, when using different disc sizes, namely tape size or split tape size, the plates can be rotated already in the processing unit so that the desired page is in a conceptual direction. Thus, for example, when handling two different sizes (ribbon size and 3 119053 halves thereof), each having the same width dimension, the sheets can be rotated if the smaller sheets are not in a vertical position (long side upright) but in a horizontal position (long side horizontal) , from which they must be taken. In the upright position, the side facing the processing direction then corresponds to the length of the side edge of the corresponding strip size screen so that both sheet qualities can be transported through the processing station so that the side edges are of equal length. This achieves various advantages, e.g. in the manufacture of laminated safety glasses, the following manufacturing and processing steps can always use a film of the same width placed on glass sheets.

10 Therefore, the glass sheets do not need to be separately rotated later. This translation has so far had to be performed at a later separate translation position.

Here, the suction frames are displaced translationally with respect to each other before the two plates 15 are pivoted in the direction of the axis of rotation so that the plates can pivot past one another. In particular, only one heel frame is moved. In this case, the rotation can occur in particular overlapping. After the translation, the translatory transfer is again performed in the opposite direction so that both plates are again at the same height in the direction of the axis of rotation.

Specifically, the device may have two adjacent suction frames that move substantially ··· ». *. synchronously with each other.

This vertical transmission operation can then be precisely electrically controlled by the toothed belts and servomotor, • · · **]. * So that the position of the bracket frame can be determined with great precision. Alternatively, the pivoting * * * ·; · * frame can be rotated by means of pins on the control device that interact with the pivoting motors that are in conjunction with the • · · gear in the bracket frame.

The invention is also directed to a processing device having a rack and a support surface for a flat material, whereby the support frame can move between the rack and e.g. a horizontal support surface, in particular by means of a guide device. The device for implementing the horizontal displacement may be, for example, a crane track, by which the translatory horizontal control device movement between the first support surface (rack) and the second support surface can be achieved.

Preferably, one of the support surfaces may be made as a vertical support surface and the other support surface as a horizontal support surface. Alternatively, both support pins or racks may be made vertical or horizontal.

The device may further be such that the support surface can be moved vertically into two opposite positions about 180 ° or 200 ° (due to offset from the vertical). Ts. especially when viewed in the direction of travel of the material, the carrier frame may be positioned with the suction means facing right or left. The bearing surface of the carrier frame can then rotate, in particular up to 270 ° and at least 240 °, and in particular at least 210 ° and especially at least 100 ° from its first vertical position to its horizontal position and thereafter possibly to its second vertical position.

Fig. 1 illustrates a double processing device according to the invention for sex placed on glass rollers 13 by a roll conveyor for manufacturing laminated safety glass panes from a glass transport or storage rack 12. The device has two racks 12 for receiving the glass plates 13, which are located on different sides of the roller conveyor table 14 in the direction of travel of the material. The stacking speed of the laminated safety glass panes can thus be doubled, whereby both glass panes 13 are subsequently joined to the laminated safety glass pane 16. In this case, the two panes 12, each with its from the rack 12 to the roller conveyor 14 associated with the rack 12 as the support frame 20 pivots relative to the guide device 28 about the horizontal pivot axis of the material and the guide device 15 moves horizontally along the crane track and engages the cradle runner.

The glass sheets 13 are then placed on a roller conveyor table 14 and fed to the subsequent production steps of the laminated glass sheet packages 16.

Fig. 1a shows an alternative or modified embodiment compared to Fig. 1, which also includes a double processing device according to the invention for placing glass sheets on a horizontal roller conveyor table 14.

Fig. 1a also shows that each bracket frame 20 has two suction frames 21 having suction ends 22 on the support surface.

At the same time, the impact of the glass pane 13 on the stop 14a determines the position of the glass pane for further processing.

Also shown in Figure 2 is a handling device according to the invention, designated 5 in its entirety by reference numeral 10, for stacking. Ts. The device of Figure 1 is a step feed device at the beginning of the production line and the device of Figure 2 at its end. The processing device 10 comprises a rack 12 in which the laminated safety glass packages 16 are placed. In addition, the processing device comprises a roller conveyor table 14 with the laminated safety glass packages 16 in a predetermined position. This processing device 10 has a support frame 20 for transferring laminated safety glass packages 16 from a stacking table 14 to a rack 12. The support frame 20 has two suction frames having suction means 22 on the support surfaces, the suction means 22 being divided into a support surface is to suck and hold the glass plate on a 16 can surface.

In the situation shown, the laminated glass has just been lifted from the roller conveyor table 14 in a horizontal position and turned upright. The laminated glass is then transferred to a rack 12. The bracket frame 20 is then rotated from a horizontal position to an upright position with the suction means 22 facing the rack 12. 20 The laminated glass pane 16 is then placed in this state, the rack 12 in the direction of the arrow 24. direction of the transport taking place in this case is used such as the crane track device 26, **. * which enables the carrier frame 20 of the horizontal movement direction of arrow 24 • • · · · "V, and in the opposite direction.

This arrangement allows the laminated safety glass pane 16 · · V to be set in a precisely defined position. The arrow 30 further indicates the direction of the glass '1' in production. The rack 12 is further made movable along track 32. The apparatus further comprises a second rack 34 for receiving laminated safety glass panes 16 and may be moved away from the crane track 26 along track 36 and then removed from it by known equipment and transported elsewhere.

In addition, the figure shows a rack 35 with glass panes, so-called cover plates 17. They are used to cover the coated sides of the laminated safety glass 16 ···: * '* · . The cover plates 17 can then also be gripped by the suction means of the bracket 20 ··· β 119053 22. To this end, the bracket 20 is rotated from its first vertical position about 180 ° to the opposite position where the bracket takes the cover 17, pivots back and puts the cover 270 °.

Alternatively, belt conveyors 15 may also be provided here, as shown in Fig. 1a.

Figure 3 illustrates a) - i) various movements of uncoated glass sheet 13 in setting-10. In representation (a), the stacker moves slowly in the positive x-direction of the given coordinate system toward the lasagne. The glass sheet is then detected by a sensor. The bracket frame 20 stops when the suction means 22 hits the glass stack. In representation (b), the suction means 22 are embossed in a glass stack. The vacuum is applied and the glass plate 13 is sucked in. In c), a vacuum is formed and the suction frame is shifted in the positive y and 15 in the negative x direction. Thus, one glass pane 13 is released from the stack of glass 13. In illustration d), the glass 13 is rotated and the carrier frame 20 lowers rapidly.

The movement of the control device 28 in the horizontal x direction is stopped when the position at which the setting on the conveyor table 14 takes place is reached. In representation e), the swivel 20 of the bracket 20 is completed and the bracket 20 is in a horizontal position. Near the roller conveyor table 14, the carrier frame 20 is lowered slowly.

Figure 4 illustrates the feed operation of a laminated safety glass manufacturing line and the insertion of a float glass of the thus distributed strip size from a rack 12 onto a roll conveyor table 14.

The glass is then ready in a rack position with the long side horizontal. In the illustration (a), both suction frames 21 are first pivoted 90 ° (Fig. 7) on a support frame 20 having two adjacent suction frames 21. The control device 28 then moves closer to the glass stack. Here, too, the sensor detects a glass stack and the control device 28 stops when the suction means 22 is pressed against the glass stack. The vacuum is turned on in representation c) and the glass 13 is aspirated. When the vacuum is formed, the carrier frame 20 and both suction frames 21 are moved upwards 10 (in the positive y direction) and in the negative x direction so that the glass 13 is released from the glass stack. The second suction frame 21 is then moved in the x direction and both suction frames 21 are rotated back 90 °. The suction frame 21, which has been moved forward, is again moved in place. Figure f) shows the pivoting movement in the z + direction and the simultaneous displacement of the control device 28 away from the glass stack. The roll conveyor table 14 is then empty at all times. The bracket frame 20 is then lowered rapidly in representation g) and the control device 28 stops when the position at which the position on the roller conveyor table 14 takes place is reached. The rotation of the support frame 20 ends when the support frame 20 reaches a horizontal position. When the carrier frame 20 comes a short distance above the roller conveyor table 14, the carrier frame 20 is lowered hi-20 again. The counting stops when the glass 13 rests on the roller conveyor table 14, such as the pre-. (h). The vacuum is removed and air is introduced into the suction device 22 and the suction frame 21 is slowly removed from the glass. The glass 13 thus sits on a roller conveyor table | * V 14. A signal is then given to start the transport of the plate and the roller conveyor • ♦ ·; * V conveyor table 14 carries the glass in the forward direction of the glass, e.g. At the same time, the carrier frame 20 is rapidly moved up and down :; is pushed in the negative z direction, and the control device 28 simultaneously moves in the direction of the rack * "12. The control device 28 advances a short distance from the glass stack, whereupon the carrier frame 20 stops when it returns to the position shown in a) and Such · • T 30-hour tape-sized boxes 13 have only half the width of the track, so that the processing unit with two suction frame systems can move two boxes at the same time, so that both boxes 13 can be placed that the width of the film to be applied in the subsequent coating of the laminated safety glass manufacturing can be optimally utilized.

Figure 5 illustrates the operations of feeding coated glass to a laminated safety glass manufacturing line. In this case, the guide device 28 is in front of the glass holder 12, and the conveyor table, which is a combination of the front belt deflector table 15 and the subsequent roller conveyor table 14 (Fig. 1a), is empty. Figure 5 then illustrates, by way of illustration a) -5 j), an operation process in which the coated glass is in the form of glass sheets 13 in a holder 12. The side facing away from the suction ends 22 of the glass sheets 13, i.e. the coated side. The control device 28 then slowly moves in the direction of the glass stack, whereupon the sensor detects the glass stack. The control device 28 stops when the suction means 22 are pressed against the glass stack and the vacuum is applied so that the glass 13 is absorbed. The suction is then performed from the uncoated side of the glass sheets 13. When the vacuum is formed, the carrier frame 20 is simultaneously moved up and away from the holder 12. This transfer is performed slowly and is illustrated in Figure c). This removes the glass from the 13 glass stacks.

If the glass has a split tape size and the device has two suction frames 21, an intermediate step is taken in which the second suction frame 21 is moved forward and both suction frames are then rotated 90 °, the first 90 ° rotation operation being performed prior to position a). After one suction frame 21 has been moved forward and both suction frames 21 have been pivoted, the second suction frame 21 moved 21 is moved back into place. This corresponds to the description of Figure 4.

The carrier frame 20 is passed through table 15 · · · * γ * and the vacuum is removed and air is supplied to the suction means 22. This will place the glass on • a * ··· * 30 tables as described in presentation f). When the lowest position is reached aaa v! 9), as shown, the lowering of the support frame 20 is stopped and the control device 28 is moved away from the holder 12. in the position shown in h). . *. starting the transport of the screen to the roller conveyor table 14 and from there to the further processing station. · * ·.

Immediately thereafter, the carrier frame is moved through the belt conveyor 15 and pivoted back, and the control device 28 moves again in the direction of the glass stack. The transport cycle ends when the initial position of the carrier frame 20 is reached and the control device 28 is in front of the glass stack close to it.

Figure 6 illustrates the process of removing a laminated safety glass package from a laminated safety glass manufacturing line, in which case the laminated safety glass package 16 is in this case transferred from a belt conveyor table 15 to a rack 12. The additional roll conveyor table (Fig. 1a) is not shown. The handling device 10 is then in the waiting position adjacent to the cutter table 15. The laminated safety glass is on the conveyor table 15 and the glass holder 12 is not yet fully packed. The handling device 10 then moves below the conveyor table 15 and stops when the inlet position is reached. Simultaneously, the vacuum is turned on and the support frame 20 is raised until the glass comes in contact and is absorbed. This is illustrated in Figures a) and b).

When position c) is reached, the other manufacturing line is released to supply the next glass to the conveyor table 15. Once the vacuum is formed, the processing device 10 is moved in the direction of the rack 12 and the support frame 20 rotates in the + z direction. The pivot operation stops as shown in (e) when the vertical end position is reached. The handling device with the control means 28 then moves in front of the glass holder 12 near it 20, after which a slow approach is performed.

In both cases, when the glass is placed in the rack 12, air is conducted to the suction ends 22 and the support frame is lowered slowly to release the vacuum. The glass 10 is then placed on the glass holder 12. The processing device 10 then moves again slowly away from the holder, thereby providing a pivoting operation while lowering the bracket 20. If the panes were split strip size plates, the two v: suction frames 21 would first be rotated 90 ° again. The bracket frame 20 stops when it has reached its lowest position and returns to its initial position.

Fig. 7 shows a support frame 20 having two suction frames 21 which can pivot about axes 23 which are perpendicular to the support plane 2. The suction frames 21 have suction heads 22 and define a support surface.

In Figure 7, both suction frames 21 take up a glass plate 13. In the plane of the drawing, the radius required to rotate the glass plate 13 of the right suction frame 21 is shown by a circle 17.

to allow translation of the two glass plates 13 one or both of the suction frame 10 is moved as indicated in Figure 8 in the direction of the arrow 19, so that the two glass sheets are superposed in the direction of the arrow 19 and the glass plates 13 can thus rotate freely accessible relative to one another about axis 23.
