Description

[0036] The invention is explained in more detail in an exemplary embodiment with reference to the drawings. The drawings show:

[0037] FIGS. 1 to 6 a side view of a turning device arranged above a conveyor belt for turning panels lying on the conveyor belt,

[0038] FIG. 7 a turning arm in a side view,

[0039] FIG. 8 shows the turning arm according to FIG. 7 in an isometric view and

[0040] FIG. 9 shows a turning device in an isometric view.

[0041] Panels 2, 3 are transported in the direction of an arrow A on a driven conveyor belt 1 (FIGS. 1 to 6) equipped with a plurality of partial belts arranged next to one another in the conveying direction. For manufacturing reasons, the panels 2, 3 are in pairs one behind the other on the conveyor belt 1.

[0042] The conveyor belt 1 consists of a plurality of spaced-apart parallel individual belts. A partial turning device of a turning device 4 is arranged in each case in the free spaces between the bands. There are at least two part-turning devices available to take the panels 2. According to the width of the panel of the panels 2, the partial turning devices can be arranged at different positions between the individual bands of the conveyor belt 1. Preferably, the distance between the partial turning devices can also be changed. In particular, the partial turning devices can be attached between different belts of the conveyor belt 1.

[0043] It is provided that only the panels 2 are to be turned by the turning device 4 while the panels 3 remain in their positions on the conveyor belt 1.

[0044] The turning device 4 comprises a turning arm 5, which in turn has two legs 6, 7 (FIG. 7, 8).

[0045] The leg 6 lying underneath in the receiving position (FIG. 1) is moved slightly upwards with its front edge by the rotary movement of the turning device 4 about a rotary joint 8 arranged in a position to be variable, so that the panel 2 can slide with its front edge onto the leg 6, being pushed onto the leg 6 by the conveyor belt 1. The leg 6 is provided with a coating on its surface, so that the panel 2 is slowed down sufficiently and does not impact in a region 9 where the two legs 6, 7 are connected to one another.

[0046] Then the panel 2 is raised by the further rotation of the turning device 4 in the direction of a rotary arrow B about the pivot 8 from its front edge (FIG. 2), so that it slides between the two legs 6, 7 upwards, while the rear Edge of the panel 2 preferably rests against the front edge of the panel 3.

[0047] The rotary movement of the turning device 4 is brought about by a drive 10 which drives a connecting rod 11 which, via an eccentric 12, causes the rotary joint 8 to rotate so that it reaches the position 8 (FIG. 2). At the same time, the turning device 4 performs a transverse movement. Here, the transverse movement is limited by a frame 13. The frame 13 is adapted to the dimensions of the panels 2; In addition, a chain drive or another drive is preferably present to implement the transverse portion of the turning device 4. The movement of the turning device is preferably limited by a contour attached to the frame 13, for example a curved contour, or by a cam disk.

[0048] The panel 2 is pushed upwards by the rotary movement of the pivot 8 and moves towards the area 9 (FIGS. 3, 4) while continuing to rest on the conveyor belt 1 with its rear edge.

[0049] The retraction movement of the connecting rod 11 shifts the pivot point of the turning device 4 to a position 8, while the panel 2 is set up between the legs 6, 7 (FIG. 4).

[0050] By turning the turning device 4 further, the panel 2 is placed on the panel 3 (FIGS. 5, 6). Then by the movement of the connecting rod 11 a reverse movement of the turning device 4 completed, so that it returns to its original position and is ready to receive another panel 2.

[0051] The turning arm 5 has at least one continuous bore 14 (FIGS. 7, 8) or an additional second bore 15, so that all turning arms 5 of the turning device 4 are connected to one another by a connecting rod 15 (FIG. 9). The turning arms 5 are mounted in a frame 20 and can, if required, be arranged at different distances from one another in the frame 20, for example shifted relative to one another. Because the distances between the turning arms 5 are variable, the turning device 4 can be easily installed on different conveyor devices and can be adapted to different distances between belts 17 of the conveyor belt 1.

[0052] The panels 2 are transported via the conveyor belt 1 to the turning arms 5 of the turning device 4, so that the panels 2 can be picked up between the legs 6 and 7 of the turning arms 5 as soon as the turning arms 5 are brought into the pick-up position by the drive 10 via the connecting rod 11. In this way, panels 2, 3 arranged one after the other in the direction of the arrow A are superimposed by the front panel 2 being placed on the subsequent panel 3 by the turning device 4 by the turning operation.

[0053] Sliding the panels 2 onto the leg 6 is preferably facilitated by the fact that the leg carries rollers 18, 19 on its upper side. Alternatively, for example, runners made of a material with low sliding friction are provided on the leg 6.

[0054] The invention thus creates a machine for continuously turning panels of building material.
