Grinding Machine

Abstract

The present invention comprises a grinding machine for grinding a metallic surface of a workpiece, wherein the grinding machine has at least one grinding apparatus, at least one transport belt (2) for transporting the workpiece through the grinding machine, and at least one suction device by means of which a workpiece lying on the transport belt (2) can be acted on with a negative pressure,
wherein the suction device has an extraction chamber (14) which is arranged below the transport belt (2) and which has a base (16) which is inclined with respect to the horizontal.

Claims

1. A grinding machine for grinding a metallic surface of a workpiece, comprising: at least one grinding apparatus; at least one transport belt for transporting the workpiece through the grinding machine; and an extraction chamber which has a base which is inclined with respect to horizontal, wherein the extraction chamber is oriented below the at least one transport belt.

2. The grinding machine according to claim 1, further comprising at least one suction device by means of which a workpiece lying on the at least one transport belt can be acted on with a negative pressure, wherein the extraction chamber is part of the at least one suction device.

3. The grinding machine according to claim 1, wherein the base of the extraction chamber encloses an angle of 5 to 30, with the horizontal.

4. The grinding machine according to claim 1, wherein the base of the extraction chamber is inclined in a direction perpendicular to a transport direction along which the workpiece is transported by the at least one transport belt.

5. The grinding machine according to claim 1 wherein the extraction chamber is connectable, at a lower end of the base to a suction device.

6. The grinding machine according to claim 1 wherein the at least one transport belt is coated with an anti-adhesion coating.

7. The grinding machine according to claim 1 wherein at least one of an inner side of the extraction chamber and the base of the extraction chamber is coated with an anti-adhesion coating.

8. The grinding machine according to claim 6 wherein the anti-adhesion coating is comprised of one or more polymers.

9. The grinding machine according to claim 1 wherein the at least one transport belt includes multiple transport belts, and further comprising multiple suction devices, wherein each of the multiple suction devices has an extraction chamber with an inclined base.

10. The grinding machine according to claim 1 wherein the at least one transport belt is exchangeable without requiring the at least one grinding apparatus to be removed.

11. The grinding machine according to claim 7 wherein the anti-adhesion coating is comprised of one or more polymers.

Description

[0039] An exemplary embodiment of the present invention will be discussed in more detail below on the basis of the appended drawings. In the drawings:

[0040] FIG. 1shows a schematic illustration of a transport table for a grinding machine,

[0041] FIG. 2shows a schematic view of an extraction chamber, and

[0042] FIG. 3shows a further schematic view of an extraction chamber.

[0043] FIG. 1 shows a transport table 1 for a grinding machine according to a first exemplary embodiment of the present invention. The figure shows a transport belt 2 which is guided over diverting rollers 4 and a tensioning device 6. The transport belt is driven by a motor (not illustrated in FIG. 1) and can move a workpiece (not illustrated) which is situated on the transport belt 2 along a transport direction T.

[0044] The transport table 1 shown in FIG. 1 stands on supports 8 which also support a grinding apparatus (not shown). For this purpose, feet 10 are provided which stand on suspension means 12 and on which a grinding apparatus frame with a grinding apparatus is arranged.

[0045] Situated below the transport belt 2 is an extraction chamber 14 which has an inclined base 16, the inclination of which runs perpendicular to the transport direction T. In the exemplary embodiment shown, the base 16 is formed so as to be inclined along a direction perpendicular to the plane of the drawing. In the context of the present invention, the extraction chamber 14 is situated below the transport belt 2, even if a return section 18 of the transport belt 2 is situated below the extraction chamber 14.

[0046] FIG. 2 shows a schematic view of the extraction chamber 14. It is possible to see the inclined base 16, whose inclination, in FIG. 2, runs from left to right, and thus perpendicular to the transport direction T. A top side 20 of the extraction chamber 14 is advantageously of open form in order that a negative pressure to be built up within the extraction chamber 14 can be transmitted to the transport belt 2 running thereabove, and thus to a workpiece situated on said transport belt.

[0047] FIG. 3 shows another view of an extraction chamber 14 with the inclined base 16. It can be seen that a height of the extraction chamber 14 is greatest in the central region, and decreases in edge regions 22. Altogether, however, the base 16 is inclined rearward in FIG. 3.

[0048] Situated within the extraction chamber 14 are strut arrangements 24, which are advantageous in particular in the case of large extraction chambers 14 for the purposes of preventing the transport belt 2 from being sucked into the extraction chamber 14. In a rear wall 26 of the extraction chamber 14 there is situated an extraction opening 28 to which an extraction device, for example a pump, can be connected, in order to act on the extraction chamber 14, and thus on the transport belt 2 running thereabove, with a negative pressure.

[0049] FIG. 1 illustrates load-bearing elements 30 which hold the extraction chamber 14 in position. If the transport belt 2 is to be exchanged, said load-bearing elements 30 must be removed. After the tensioning device 6 has been detached, the transport belt 2 can then be easily removed, without further rearrangement or dismounting of other components of the grinding machine.
