SORTING PLANT FOR LONG-TERM OBJECTS SUCH AS PLATES AND BOARDS

This invention relates to sorting facilities for elongate objects, such as planks and planks, which sort these objects into different trays depending on length, width, thickness or other characteristics. Endless belts arranged around the pulleys and side by side feed said objects towards the arms to be folded down above the trays.

The invention according to the features of the following claims will become apparent from the following description with reference to the accompanying drawings, in which:

Figure 1 is a schematic side view of a part of a sorting plant according to the invention; Figure 2 is a plan view thereof;

Fig. 3 is a side view on a larger scale of the portion delimited by A-A in Fig. 1, and

Figure 4 is a sectional view of the plant taken along line B-B of Figure 3.

The plant shown has a plurality of belts, preferably V-belts arranged around the pulleys 20 1 and 2, which wheels are arranged parallel to each other on horizontal shafts 3 and 4 and on shaft pins 5 and 6. Shafts 3 and 4 are rotatably mounted on frame-mounted bearings and shaft pins 5 are also attached to the frame. The upper runs of the endless belts 7 arranged around the pulleys 1 and 2 arranged on the shafts 3 and 4 are horizontal and extend in the longitudinal direction of the plant and the same is true of the endless belts 17 arranged around the pulleys on the shaft pins 5 and the shafts 4. The shaft pins 30 6 with their pulleys 8 are arranged at the end of a rotatable arm 9 arranged around each shaft 4. The belts 11 are arranged around the respective pulleys of the pulleys 8 and the shafts 4. The shaft pins 6 are located so that in the upturned position of the arms 9 these shaft pins 35 are at the same height and in line with the frame pins 5 of the frame fixed 2 70531 with the pulleys 8 laterally displaced with respect to the pulleys of the shaft pins 5, as shown in Figures 2 and 3. reversible, driven by a motor 5 not shown with successively arranged drive chains 10 relative to each other.

The arms 9 are located above the trays 12, which are intended for receiving objects of a certain length, width or the like. The arms 9 are controlled 10 by pneumatic or hydraulic cylinders 13. These cylinders are manually controllable, but may also be connected to object measuring devices adapted to give a pulse to turn the arms 9 downwards above a certain compartment, with objects approaching this compartment approaching. .

Above each compartment is an intermediate compartment 14, the bottom of which has an opening 16 normally closed by controllable hatches or rods 15. These hatches can be controlled by a person at the lo-20 compartment. The function of the intermediate compartment is first to receive and collect planks or other objects of a certain quality or size, after which the newly mentioned user opening the door or bars can drop them down into tray 12.

Claims (5)

A sorting plant for lowering elongate objects such as planks and planks into different trays (12) for feeding objects with used endless belts (7 and 11) arranged side by side and passed around the belt pulleys (1,2 and 8), characterized in that each tray (12) ) are fitted with frame-mounted bearings with rotatably mounted successively mounted shafts (3 and 4) 10 and bearing pulleys (1, 2 and 8) and then downwardly pivotable arms (9) after the latter shaft (4), supporting axle pins ( 6) with pulleys (8) around and around said shaft (4) endless belts (11), the arms being connected to pneumatic or hydraulic cylinders (13) or the like for turning the arms down to an object in a lowering position and for turning back upwards to a position , where the upper strap of the latter belts is horizontal. Sorting plant according to Claim 1, characterized in that the movements of the cylinders (13) or the like are adapted to be controlled by electrical measuring devices which measure the length or other dimension of the objects. Sorting plant according to Claim 1 or 2, characterized by "down-opening intermediate compartments (14) arranged under the foldable arms (9) for the temporary collection of objects. 3 70531 Sorting plant according to Claim 3, characterized by removable hatches or rods (15) arranged parallel to one another in the bottom of the intermediate compartments (14) for lowering objects. Sorting plant according to one of Claims 1 to 4, characterized in that the frame-mounted shafts (4) around which the arms (9) can be pivoted are driven by a motor by endless belts (10) or other transmission devices between said shafts.
