Abstract

The invention relates to a splicer device comprising a first unwinding device to unwind a non-endless first material web and a second unwinding device to unwind a non-endless second material web as well as a joining device for joining together the non-endless material webs to form an endless material web. The splicer device further has a storage carriage, which comprises at least one deflection roller to deflect the endless material web and is displaceable between two end positions to form or loosen material web loops of the endless material web. The at least one deflection roller has a respective central longitudinal axis and is tiltable between two tilt end positions to influence a running direction of the endless material web. The splicer device further has an information processing unit to cause tilting of the at least one deflection roller depending on positional information regarding the endless material web and/or another endless material web to be joined thereto.

Claims

1. A splicer device for splicing material webs, comprising

a) a first unwinding device to unwind a non-endless first material web from a first material roll,

b) a second unwinding device to unwind a non-endless second material web from a second material roll,

c) a joining device for joining together the non-endless first material web and the non-endless second material web to form an endless material web,

d) a storage carriage which

i) comprises at least one deflection roller to deflect the endless material web, and

ii) is displaceable along a displacement path between a first end position and a second end position allowing one of the formation and loosening of material web loops of the endless material web,

iii) wherein the at least one deflection roller

has a respective central longitudinal axis, and

is tiltable between a first tilt end position and a second tilt end position by tilting the respective central longitudinal axis to influence a running direction of the endless material web, and

e) an information processing unit to cause tilting of the at least one deflection roller depending on positional information regarding at least one of the endless material web and another endless material web to be joined to the endless material web.

2. A splicer device according to claim 1, wherein during tilting, at least an end region of the at least one deflection roller moves substantially along a section of the displacement path of the storage carriage.

3. A splicer device according to claim 1, wherein in at least one of its first tilt end position and second tilt end position, the at least one deflection roller forms a maximum tilt angle of between 0.5°

and 5°

relative to a neutral position of the at least one deflection roller.

4. A splicer device according to claim 1, wherein the storage carriage is substantially entirely tiltable in order to tilt the at least one deflection roller.

5. A splicer device according to claim 1, wherein the storage carriage is displaceable between the first end position and the second end position by actuating a displacement assembly.

6. A splicer device according to claim 5, wherein the storage carriage has two opposite side regions, wherein the displacement assembly is in an actuating connection with the two side regions of the storage carriage to tilt said storage carriage along the displacement path.

7. A splicer device according to claim 6, wherein the displacement assembly comprises

a) a first displacement drive which is in one of a direct and an indirect actuating connection with the first side region of the storage carriage to displace said storage carriage along the displacement path, and

b) a second displacement drive which is in one of a direct and an indirect actuating connection with the second side region of the storage carriage to displace said storage carriage along the displacement path,

c) wherein the two displacement drives are actuable independently of each other to tilt the at least one deflection roller.

8. A splicer device according to claim 7, wherein the first displacement drive is in actuating connection with the first side region of the storage carriage via a first transmission element, and the second displacement drive is in actuating connection with the second side region of the storage carriage via a second transmission element.

9. A splicer device according to claim 6, wherein the displacement assembly comprises precisely one displacement drive which is in one of a direct and an indirect actuating connection with a rotatably drivable coupling part to displace the storage carriage.

10. A splicer device according to claim 9, wherein the coupling part is tiltable, wherein spaced-apart coupling part portions thereof are in actuating connection with the side regions of the storage carriage to tilt the at least one deflection roller.

11. A splicer device according to claim 9, wherein the displacement assembly comprises a tilt drive to tilt the coupling part.

12. A splicer device according to claim 9, wherein the coupling part is tiltably mounted in at least one pendulum bearing.

13. A corrugated cardboard installation for producing corrugated cardboard webs, comprising

a) at least one splicer device according to the invention,

b) a first sensor assembly that is in signal connection with the information processing unit to detect the position of the endless material web, and

c) a second sensor assembly that is in signal connection with the information processing unit to detect the position of another endless material web.

14. A corrugated cardboard installation for producing corrugated cardboard webs according to claim 13, wherein the first and second sensor assembly are in each case arranged upstream of a corrugated cardboard production assembly to produce a corrugated cardboard web.
