Abstract
A switching device (130) for transferring and ejecting a plate element (20) in a sorting unit (100), comprises: transport means (132), capable of transporting (A) the plate element (20) from upstream to downstream; a pivot (134), positioned in an upstream portion of the transport means (132), and allowing the transport means (132) to tilt relative to a horizontal transverse axis (R2); and raising means (135), secured in a downstream portion of the transport means (132), for tilting the downstream portion of the transport means (132) between a high first position and a low second position, and vice versa, so as to switch the plate element (20), respectively upward and downward.
Claims10
A switching device for transferring and ejecting a plate element in a sorting unit, the switching device comprising:
- a transport conveyor to operate at a first travel speed upon both receipt of the plate element at an upstream entry of the transport conveyor and conveyance of the plate element from the transport conveyor at a downstream exit of the transport conveyor;
- a pivot, positioned in an upstream portion of the transport conveyor, and allowing the transport conveyor to tilt relative to a horizontal transverse axis of the transport conveyor;
- and
- a raising means comprising an eccentric mechanism, secured in a downstream portion of the transport conveyor, to tilt the downstream portion of the transport conveyor between a high first position and a low second position, and vice versa, so as to switch the plate element, respectively upward and downward independently from a conveying movement of the transport conveyor,
- wherein the eccentric mechanism further comprises a rotary eccentric shaft having an eccentric section having a first rotary shaft and a non-eccentric section having a second rotary shaft offset from the first rotary shaft in a radial direction relative to an axis of rotation of the rotary eccentric shaft.
A sorting unit comprising:
- a switching device for transferring and ejecting a plate element in the sorting unit, the switching device comprising:
- a transport conveyor to operate at a first travel speed upon both receipt of the plate element at an upstream entry of the transport conveyor and conveyance of the plate element from the transport conveyor at a downstream exit of the transport conveyor;
- a pivot, positioned in an upstream portion of the transport conveyor, and allowing the transport conveyor to tilt relative to a horizontal transverse axis of the transport conveyor;
- and
- a raising means, secured in a downstream portion of the transport conveyor, to tilt the downstream portion of the transport conveyor between a high first position and a low second position, and vice versa, so as to switch the plate element, respectively upward and downward independently from a conveying movement of the transport conveyor,
- a first downstream module, an input of the first downstream module being situated downstream of the downstream exit of the transport conveyor, when the transport conveyor is in the high first position, and
- a second downstream module, an input of the second downstream module being situated downstream of the downstream exit of the transport conveyor, when the transport conveyor is in the low second position,
- wherein a conveyor of the first downstream module is offset in a direction, parallel to the horizontal transverse axis of the transport conveyor, from a conveyor of the second downstream module, and the second downstream module is nested inside the first downstream module.
