Abstract

A description of a continuous conveyor is provided. The continuous conveyor includes a front segment, a central segment and a rear segment. At least the central segment has a conveying device for conveying objects and at least one height-adjustment device for adjusting the height of at least the conveying device from at least one lower, use position for conveying objects into an upper position. In a conveying position, the front segment, the conveying device of the central segment and the rear segment are arranged one behind the other in at least one conveying direction. Provision is made for a free space beneath the conveying device of the central segment in the upper position. The free space has a height of at least 160 cm, a width of at least 70 cm, and a depth corresponding to the width of the conveying device of the central segment.

First claim

The invention claimed is:

1. A continuous conveyor, in particular belt conveyor or roller conveyor, for conveying objects, comprising:
a front conveying segment,
a central conveying segment, and
a rear conveying segment,
wherein at least the central conveying segment has a conveying device for conveying objects and at least one height-adjustment device for adjusting the height of at least the conveying device from at least one lower, use position for conveying objects into an upper position in relation to the front conveying segment and the rear conveying segment,
wherein, in a conveying position, the front conveying segment, the conveying device of the central conveying segment and the rear conveying segment are arranged one behind the other in at least one conveying direction,
wherein a free space, in particular a through-passage, is provided beneath the conveying device of the central conveying segment in the upper position, said free space having a height of at least 160 cm, preferably at least 175 cm, in particular at least 190 cm, a width of at least 70 cm, preferably at least 90 cm, in particular at least 110 cm, and a depth corresponding to the width of the conveying device of the central conveying segment, and
wherein the height-adjustment device has at least one counterweight for at least partially compensating for the weight of the conveying device of the central conveying segment when the conveying device is being adjusted from the lower, use position into the upper position, and back,
wherein the height adjustment device for adjusting the height of the conveyor device of the central conveyor segment is designed in the form of a purely mechanical height adjustment device for purely mechanical, manual height adjustment of the conveyor device of the central conveyor segment, and wherein the conveying device of the central conveying segment has at least one handle for the manual height adjustment of the conveying device of the central conveying segment, and wherein the conveying device of the central conveying segment has in each case at least one handle for the manual height adjustment of the conveying device of the central conveying segment on opposite sides as seen in respect of the conveyor track for conveying objects.

2. The continuous conveyor according to claim 1 , wherein at least one conveying surface of the front conveying segment, at least one conveying surface of the conveying device of the central conveying segment in the lower, use position and at least one conveying surface of the rear conveying segment form an at least essentially continuous conveyor track for conveying objects from the front conveying segment, via the central conveying segment, to the rear conveying segment.

3. The continuous conveyor according to claim 1 , wherein the upper position of the conveying device of the central conveying segment is a not-in-use position, in which objects are not conveyed, and wherein, preferably, the at least one conveying surface of the conveying device of the central conveying segment in the upper position together with the conveying surfaces of the front conveying segment and of the rear conveying segment do not form an at least essentially continuous conveyor track for conveying objects from the front conveying segment, via the central conveying segment, to the rear conveying segment.

4. The continuous conveyor according to claim 1 , wherein at least one foot with a standing surface, said foot being assigned in particular to the central conveying segment, is provided for positioning the continuous conveyor on an underlying surface, and/or wherein at least part of an underside of the conveying device of the central conveying segment in the upper position is arranged at least 160 cm, preferably at least 175 cm, in particular at least 190 cm above the standing surface, and/or wherein at least part of the underside of the conveying device of the central conveying segment in the upper position is arranged at most 240 cm, preferably at most 220 cm, in particular at most 200 cm above the standing surface.

5. The continuous conveyor according to claim 1 , wherein the central conveying segment has in each case at least one leg at the front and rear, as seen in the conveying direction of the objects, and wherein, preferably, the length of the legs beneath a portion of the conveying device which extends between the legs is at least 160 cm, preferably at least 175 cm, in particular at least 190 cm long.

6. The continuous conveyor according to claim 1 , wherein the central conveying segment has at least one automatic arresting device for automatically arresting the conveying device of the central conveying segment in the lower, use position and/or in the upper position.

7. The continuous conveyor according to claim 1 , wherein the height-adjustment device is designed such that the operation of raising the conveying device from the lower, use position into the upper position and/or the operation of lowering the same from the upper position into the lower, use position require/requires a force of less than 300 N, preferably less than 260 N, in particular less than 220 N.

8. The continuous conveyor according to claim 1 , wherein the conveying device of the central conveying segment is designed to be rectilinear or curved along the conveyor track and/or the conveying direction of the conveying device of the central conveying segment.

9. The continuous conveyor according to claim 1 , wherein the conveying device of the central conveying segment has a motor drive for driving the conveying device for conveying the objects.

10. The continuous conveyor according to claim 1 , wherein the conveying device of the central conveying segment has a roller conveyor and/or a belt conveyor.

11. The continuous conveyor according to claim 1 , wherein the front conveying segment, if required a conveying device of the front conveying segment, and/or the rear conveying segment, if required a conveying device of the rear conveying segment, have/has a roller conveyor and/or a belt conveyor, and/or wherein the front conveying segment has a height-adjustment device for adjusting the height of the conveying device of the front conveying segment and/or the rear conveying segment has a height-adjustment device for adjusting the height of the conveying device of the rear conveying segment.

12. An object-conveying facility comprising:
at least one continuous conveyor according to claim 1 ,
wherein a through-passage is provided, in particular in a direction transverse to the conveyor track and/or conveying direction, beneath the conveying device of the central conveying segment in the upper position, said through-passage having a height of at least 160 cm, preferably at least 175 cm, in particular at least 190 cm, and a width of at least 70 cm, preferably at least 90 cm, in particular at least 110 cm, and a depth corresponding to the width of the conveying device of the central conveying segment.

13. The object-conveying facility according to claim 12 , wherein at least part of the underside of the conveying device of the central conveying segment in the upper position is arranged at least 160 cm, preferably at least 175 cm, in particular at least 190 cm above the floor of the object-conveying facility beneath the conveying device, and/or wherein at least part of the underside of the conveying device of the central conveying segment in the upper position is arranged at most 240 cm, preferably at most 220 cm, in particular at most 200 cm above the floor of the object-conveying facility beneath the conveying device.

14. A continuous conveyor, in particular belt conveyor
