Separating apparatus for tubular or bar-shaped workpieces
A separating apparatus for the controlled separation of tubular or bar-shaped workpieces has a pivot unit with a storage frame and a lifter. The storage frame is configured to receive a plurality of tubular or bar-shaped workpieces and the lifter is configured to lift the workpieces stored in the storage frame. A conveyor unit has a conveyor slide which forms an inclined conveyor plane for the tubular or bar-shaped workpieces. The pivot unit and the conveyor unit can be arranged in such a manner with respect to each other that a first pivot axis, about which the storage frame of the pivot unit is pivotable, extends along an upper end of the conveyor slide of the conveyor unit. There is also described a loading system with the separating apparatus and a method for using the separating apparatus.
1 . A separating apparatus for a controlled separation of tubular or bar-shaped workpieces, the separating apparatus comprising:
a pivot unit having a storage frame configured to receive a plurality of the tubular or bar-shaped workpieces and a lifter configured to lift the workpieces stored in said storage frame; and
said storage frame of said pivot unit being pivotally mounted about a first pivot axis;
a conveyor unit forming a conveyor slide with an inclined conveyor plane for the tubular or bar-shaped workpieces;
said pivot unit and said conveyor unit to be arranged with respect to each other such that said first pivot axis of said storage frame extends along an upper end of said conveyor slide of said conveyor unit; and
said conveyor unit having a bridging element being pivotably supported about a second pivot axis at the upper end of said conveyor slide and being configured to bridge a gap between the upper end of said conveyor slide and an upper end of a lateral delimitation of said storage frame of said pivot unit;
said bridging element having a predetermined width; and
said pivot unit and said conveyor unit being arranged with respect to each other such that the first pivot axis of said pivot unit and said second pivot axis of said bridging element of said conveyor unit correspond to one another.
2 . The separating apparatus according to claim 1 , wherein said upper end of said lateral delimitation of said storage frame is pivotable in a predetermined radius about the first pivot axis, and the predetermined radius substantially corresponds to the predetermined width of said bridging element.
3 . The separating apparatus according to claim 1 , wherein said conveyor unit comprises one or more carriers which are displaceably arranged along the conveyor plane in a conveying direction, enabling the tubular or bar-shaped workpieces that are lifted by the lifter from the storage frame via the upper end of said lateral delimitation and that reach the conveyor plane of said conveyor slide to be conveyed in a controlled manner along the conveyor plane.
4 . The separating apparatus according to claim 1 , wherein at least one of the following is true:
said pivot unit has a base module and a pivotable pivot module;
said storage frame is arranged on said pivot module;
said pivot module has an at least partially curved outer contour which extends in a radius about the first pivot axis; or
said pivot unit has a drive with a drive wheel which is arranged on said base module and which, in order to pivot said pivot module, is in engagement with a curved outer contour of said pivot module.
5 . The separating apparatus according to claim 1 , wherein said pivot unit is a displaceable unit.
6 . The separating apparatus according to claim 1 , further comprising:
a control unit configured to control a pivoting movement of said pivot unit, a lifting movement of said lifter, and a displacement movement of at least one carrier that is displaceable along the conveyor plane to separate a desired number of the tubular or bar-shaped workpieces from the storage frame via the conveyor unit.
7 . A loading system, comprising:
a processing machine for processing tubular or bar-shaped workpieces, said processing machine having a loading region, a processing region, and an unloading region;
a separating apparatus according to claim 1 for a controlled separation of the tubular or bar-shaped workpieces; and
a loading apparatus arranged between the conveyor unit of said separating apparatus and said loading region of said processing machine, said loading apparatus having at least one gripper configured to remove individual tubular or bar-shaped workpieces from the conveyor unit and to transfer the workpieces into said loading region of said processing machine.
8 . The loading system according to claim 7 , further comprising:
a shelf for receiving storage frames; and
wherein the pivot unit of said separating apparatus is configured to move back and forth between said shelf and the conveyor unit of said separating apparatus in order to be loaded on said shelf with a storage frame which is loaded with tubular or bar-shaped workpieces and to separate the workpieces in conjunction with said conveyor unit.
9 . A method for loading a processing machine with tubular or bar-shaped workpieces, the method comprising:
providing a separating apparatus according to claim 1 , wherein the conveyor unit of the separating apparatus has at least one carrier;
loading the storage frame with tubular or bar-shaped workpieces;
subsequently pivoting the pivot unit from a loading orientation into a separation orientation;
subsequently lifting, using the lifter, the tubular or bar-shaped workpieces in the storage frame until at least one of the tubular or bar-shaped workpieces bears on the at least one carrier; and
subsequently lowering the at least one carrier along the conveyor plane of the conveyor unit.
