Abstract

The invention relates to a holding fixture for the drive unit of a transport device that transports products to be weighed, wherein, for transferring the weight force to be detected, the holding fixture is arranged between the transport device and the weighing cell detecting the weight.

Claims

1. Holding fixture for the drive unit of a transport device,

a) wherein the transport device is constructed for transporting products (G), the weight force of which is to be detected in the weighing cell of a scale, and

b) wherein the weighing cell experiences the weight force to be detected via a force introduction area, and

c) wherein the weighing cell experiences the weight force (G) to be detected in the direction of an imaginary force introduction axis passing through the force introduction area, characterized in that

d) in order to transmit the weighing force from the transport device into the weighing cell, the holding fixture can be provided therebetween.

2. Holding fixture according to claim 1, characterized in that the drive unit is arranged in the holding fixture such that the center of gravity resulting from the holding fixture and the drive unit lies substantially close to or within the force introduction axis.

3. Holding fixture according to claim 1, characterized in that the drive unit is arranged in the holding fixture such that the resulting center of gravity of the holding fixture, the drive unit and the transport device lies substantially close to or within the force introduction axis.

4. Holding fixture according to one of the preceding claims, characterized in that the holding fixture accommodating the drive unit has a metallic, substantially tightly encapsulated housing for improving the electromagnetic compatibility.

5. Holding fixture according to one of the preceding claims, characterized in that the holding fixture accommodating the drive unit has a housing for removing or shielding drive heat from the drive unit.

6. Holding fixture according to one of the preceding claims, characterized in that the holding fixture has a housing for ingress protection of the components arranged therein.

7. Holding fixture according to one of the preceding claims, characterized in that the holding fixture has a housing for explosion protection of the components arranged therein.

8. Holding fixture according to one of the preceding claims, characterized in that the holding fixture has on its side facing the weighing cell a mechanical and/or electrical plug connector cooperating complementarily with the weighing cell, with which the holding fixture and/or the drive unit arranged therein is detachably connectable mechanically and/or electrically to the weighing cell.

9. Holding fixture according to one of the preceding claims, characterized in that the electrical connection is explosion-protected and/or ingress-protected and/or encapsulated for improved electromagnetic compatibility.

10. Holding fixture according to one of claims 8 or 9, characterized in that the electrical connection can be automatically made or broken by placing the holding fixture on, or removing the holding fixture from, the weighing cell.

11. Holding fixture according to one of claims 8-10, characterized in that the electrical connection has a protection mechanism that automatically protects the electrical contacts on the weighing cell and/or the holding fixture against unintentional contact during the breaking of the connection.

12. Holding fixture according to one of the preceding claims, characterized in that the holding fixture can be detachably connected to or locked to the weighing cell and/or the transport device via a locking mechanism that preferably can be operated without tools.

13. Holding fixture according to one of the preceding claims, characterized in that the width of the holding fixture is selected to be not greater than the width of the transport device and/or the weighing cell.

14. Holding fixture according to one of the preceding claims, characterized in that the holding fixture comprises drive means that can be connected to the transport device for its conveying operation at a coupling point lying between at least two conveying elements that move the products in the conveyance direction.

15. Holding fixture according to one of the preceding claims, characterized in that an overload safety device cooperating with the weighing cell and/or another contact component is provided on the holding fixture.

16. Scale with at least one associated holding fixture according to one of the preceding claims.
