(3) FIG. 2: shows the device from FIG. 1 in a top view,
(4) FIG. 3: shows a second embodiment of the device according to the present invention for processing concrete blocks in a side view,

(6) FIG. 5: shows a method for processing concrete blocks in a schematic representation.
DETAILED DESCRIPTION OF THE INVENTION
(7) FIG. 1 shows a first embodiment of a device 1 according to the present invention for processing concrete blocks 2. The device 1 comprises a device 3 for the transport of the concrete blocks 2. The transport device 3 runs in the horizontal direction and conveys the concrete blocks 2 along a direction of transport T. Moreover, the device 1 comprises means 4 for the mechanical processing of the edges of the concrete blocks 2. In the case of the device 1 depicted in FIG. 1 and preferred in this respect, the means 4 are designed as cylindrical rollers 4. The rollers 4 are arranged above the transport device and are pivot-mounted in each case on two arms 5A, 5B (arm 5B is hidden in FIG. 1). While the rollers 4 are mounted on the one end of the arms 5A, 5B, the other ends of the arms 5A, 5B are pivotably connected with a frame 7 via a bearing 6. Moreover, spiral springs 8A, 8B are provided between each arm 5A, 5B and the frame 7.
(8) In FIG. 2 the device 1 from FIG. 1 is shown in a top view. The areas of the device 1 already described in connection with FIG. 1 are provided in FIG. 2 with corresponding reference signs. In the top view, it can be clearly seen that four rows of concrete blocks 2 are arranged next to each other on the transport device 3 and are moved in the direction of transport T. A roller 4 is assigned to each row of concrete blocks 2. The rollers 4 are connected with the frame 7 in each case via two arms 5A, 5B running parallel. Moreover, each arm 5A, 5B is connected with the frame 7 via a spiral spring 8A, 8B. In the case of the first embodiment of the device 1 depicted in FIG. 1 and FIG. 2, all four rollers 4 are arranged on the same axis of rotation 9.
(9) FIG. 3 shows a second embodiment of a device 1′ according to the present invention for processing concrete blocks 2. The areas of the device 1′ already described in connection with FIG. 1 or FIG. 2 are provided in FIG. 3 with corresponding reference signs. The essential difference between the first embodiment of the device 1 and the second embodiment of the device 1′ lies in the fact that the second embodiment of the device 1′ has seven rollers 4, 4′ and thus can simultaneously process seven rows of concrete blocks 2. Due to lack of space, the rollers 4, 4′ are arranged offset in the case of the second embodiment of the device 1′: four rollers 4 are arranged on a first axis of rotation 9, while three other rollers 4′ are arranged on a second axis of rotation 9′, which is offset relative to the first axis of rotation 9 in the direction of transport T. In the case of the embodiment of the device 1′ shown in FIG. 3, the rollers 4, 4′ are also mounted pivotably in each case on two arms 5A, 5B, 5A′, 5B′ (arms 5B, 5B′ are hidden in FIG. 3). The pivotable connection of the arms 5A, 5B, 5A′, 5B′ to the frame 7 occurs—as was already previously described—via bearings 6 and spiral springs 8A, 8B, 8A′, 8B′.
(10) In FIG. 4 the device 1′ from FIG. 3 is shown in a top view. The areas of the devices 1, 1′ already described in connection with FIG. 1 to FIG. 3 are provided in FIG. 4 with corresponding reference signs. In the top view, it can be clearly seen that seven rows of concrete blocks 2 are arranged next to each other on a transport device 3 and are moved in the direction of transport T. A roller 4, 4′ is assigned to each row of concrete blocks 2. The front rollers 4 are connected with the frame 7 via the arms 5A, 5B running parallel and the back rollers 4′ are connected with the frame 7 via the arms 5A′, 5B′ running parallel. The arms 5A, 5B of the front rollers 4 and the arms 5A′, 5B′ of the back rollers 4′ are arranged alternately due to the overlapping position of the rollers 4, 4′. Each arm 5A, 5B, 5A′, 5B′ is connected with the frame 7 via a spiral spring 8A, 8B, 8A′, 8B′. In the case of the second embodiment of the device 1′ depicted in FIG. 3 and FIG. 4, the rollers 4, 4′ are arranged on different axes of rotation 9, 9′: the front four rollers 4 are arranged on the front axis of rotation 9 and the back three rollers 4 are arranged on the back axis of rotation 9′.
(11) The devices 1, 1′ shown in FIG. 1 to FIG. 4 are not specified for four or seven rollers 4, 4′, but rather can be adapted to any number of rollers 4, 4′. The rollers 4, 4′ can be arranged on the same axis of rotation 9 or on two or more different axes of rotation 9, 9′.
(12) FIG. 5 shows a method for processing concrete blocks 2 in a schematic representation. The method comprises the following steps: a) moulding the concrete blocks, b) mechanical processing of the edges of the concrete blocks, b2)/b3) cleaning/vacuum cleaning of the concrete blocks, b4) coating of the concrete blocks, c) curing the concrete blocks. The steps a), b), and c) are mandatorily required, while the steps b2), b3) and b4) are merely optional—although very advantageous.
