Abstract

A lifting and conveying device includes a lifting body, a revolving conveyor element, and a linear drive. The revolving conveyor element is deflected on the lifting body to a conveyor path on which an item can be conveyed. The lifting body is engageable or engaged by the linear drive of the device for a lifting of the conveyor path.

First claim

What is claimed is:

1. A lifting and conveying device, comprising:
a lifting body;
a revolving conveyor element deflected on the lifting body to a conveyor path configured such that an item is conveyed along the conveyor path;
a linear drive including a rotary motor and a motor gear, the linear drive configured to engage the lifting body in order to lift the conveyor path, the motor gear including a cam disk rotationally driven by the rotary motor and configured to convert an angle of rotation into the lifting of the conveyor path, the cam disk being indirectly or directly engaged or engagable with the lifting body;
a base body that is stationary with respect to a section conveyor, the rotary motor and the cam disk supported by the base body; and
a tensioning member that tensions the lifting body against the cam disk.

2. The lifting and conveying device according to claim 1 , wherein the rotary motor includes an electric motor.

3. The lifting and conveying device according to claim 2 , wherein the electric motor is a stepping motor.

4. The lifting and conveying device according to claim 1 , further comprising:
a conveyor motor configured to drive the revolving conveyor element; and/or
a conveyor gear configured to couple to a drive of the section conveyor.

5. The lifting and conveying device according to claim 1 , wherein:
the cam disk includes an eccentric control surface having a radial spacing defined from an axis of rotation of the cam disk to the eccentric control surface; and
the radial spacing depends on a circumferential angle of the cam disk.

6. The lifting and conveying device according to claim 5 , wherein the eccentric control surface is configured to slide along a lifting body portion or to roll along a rolling body rotatably connected to the lifting body.

7. The lifting and conveying device according to claim 5 , wherein:
the radial spacing increases with an increase in the circumferential angle from a minimum value to a maximum value; and/or
the radial spacing increases with an increase in the circumferential angle from a minimum value to a maximum value and then decreases again.

8. The lifting and conveying device according to claim 5 , wherein the eccentric control surface is divided in a circumferential direction into lifting portions which cause different lifting speeds at a constant rotational speed of the cam disk.

9. The lifting and conveying device according to claim 5 , wherein the eccentric control surface is divided in a circumferential direction into at least one latching portion which brings the lifting body to a stop.

10. The lifting and conveying device according to claim 9 , wherein the at least one latching portion is arranged (i) in a circumferential angle region of the minimum value or the maximum value, or (ii) in a circumferential angle region between the minimum value and the maximum value.

11. The lifting and conveying device according to claim 9 , wherein:
the at least one latching portion includes a concave recess or depression;
the eccentric control surface is configured to slide along a lifting body portion or to roll along a rolling body rotatably connected to the lifting body; and
the lifting body portion or rolling body is configured to dip, at least in sections, into the concave recess or depression.

12. The lifting and conveying device according to claim 11 , wherein the at least one latching portion is configured to be arranged in positive fit with the lifting body portion or a portion of the rolling body.

13. The lifting and conveying device according to claim 9 , wherein edges of at least one latching portion are arranged in the circumferential direction and are rounded.

14. The lifting and conveying device according to claim 1 , wherein the tensioning member is a spring.

15. The lifting and conveying device according to claim 14 , further comprising:
at least one belt pulley configured to drive a conveyor belt of the lifting and conveying device, the at least one belt pulley being movable with the lifting body.

16. The lifting and conveying device according to claim 15 , wherein the at least one belt pulley and the lifting body are supported by a support structure, and the spring biases the support structure relative to the base body so as to tension the lifting body against the cam disk.

17. A device, comprising:
a first conveyor element which revolves along a first conveyor path; and
a lifting and conveying device configured to lift and move an item from the first conveyor path, the lifting and conveying device arranged in a stationary manner on the first conveyor path, the lifting and conveying device comprising:
a lifting body;
a revolving conveyor element deflected on the lifting body to the first conveyor path so as to move the item along the conveyor path;
a linear drive including a rotary motor and a motor gear, the linear drive configured to engage the lifting body in order to lift the first conveyor path, the motor gear including a cam disk rotationally driven by the rotary motor and configured to convert an angle of rotation into the lifting of the first conveyor path, the cam disk being indirectly or directly engaged or engagable with the lifting body;
a base body that is stationary with respect to the first conveyor element, the rotary motor and the cam disk arranged on the base body; and
a tensioning member that tensions the lifting body against the cam disk.
