Definitions

  • the invention relates to a system for processing bar material such as reinforcing steel comprising at least one bending device with one of these upstream material storage and a downstream storage for the processed material.
  • the object of the present invention is to design a system of the type mentioned at the outset such that, with structurally simple means, continuous input and output of the rod material to be machined or machined to and from the bending device is possible without the need for the and issuing separate facilities are required.
  • the object is achieved in that the material can be transported both to the bending device and after its processing away from it by means of arms pivotably arranged on both sides of the bending device, that the pivot axis of the arms in the transport direction of the material behind the bending device and vertically to the direction of transport, that in front of the bending device an inclined ramp-shaped element is arranged, on which material gripped by the arms can be placed, and that each arm has a step which runs in the region of the ramp-shaped element and in which the material placed in front of the bending device when lifting the Poor is durable.
  • an insertion and ejection device for rod material is made available, which can be referred to as a fork device, which in turn has arms that can be pivoted laterally next to the bending device and are rigidly connected to a shaft.
  • the shaft runs behind the tool, so that when the arms are pivoted, material that is to be machined and machined can be lifted and fed to the bending device or the tray.
  • the arm is consequently divided into two areas, namely a rear area which is remote from the pivot axis, in which the material to be processed is placed and from which it can only slide up to the step, and a front area which grips the processed material and from which it slides onto the shelf.
  • the arms are pivoted to such an extent that the step runs above the infeed runner before the arms are lowered again into the basic position so that the rod-shaped material is deposited on the infeed runner or skids and slide from there to the bending device can.
  • the shaft with the arms extending rigidly therefrom can be moved as a unit parallel to the bar material, in order to make it possible to raise it in the points that bending does not occur; because the corresponding material can easily have lengths of 20 m.
  • the arms extend over the pivot axis thereof in the direction of the tray.
  • a system for processing bar material such as reinforcing steel is shown, which among other things. has a material store (12) with a template platform (14), a processing machine (16) with a bending device (18) and a storage rack (22) comprising a tray (20).
  • Swiveling arms (24) and (26) are arranged laterally to the processing machine (16) and thus to the bending device (18), which are rigidly connected to a shaft (28) which is itself held by the processing machine (16) and parallel to the Longitudinal axes of the rod material (10) runs.
  • the shaft (28) is in relation to the transport direction of the Bar material (10) from the template platform (14) via the bending device (18) to the tray (20) in the rear area, that is, arranged behind the bending device (18).
  • each arm (24), (26) has a step (38) which serves as a stop for the rod materials (40) applied to the free end of the arms (24), (26) when the arms (24) , (26) according to FIG. 3 (position B) are pivoted in a raised position.
  • the rod material (10) is loaded and unloaded to and from the bending device (18) without manual intervention or additional auxiliary elements are required.
  • the procedure for loading and unloading the bar stock is as follows.
  • bar material is placed on the end (42) of the arms (26) and (24) which is remote from the shaft (28).
  • the material is provided with the reference number (40) there.
  • the arms (24), (26) are then raised from the basic position A to the position B, as a result of which the material (40) slides against the shoulder formed by the step (38).
  • the step (38) is above the inlet runners (34), (36), which are arranged in front of the bending device (18). If the arm (24) is now moved back to the basic position A (FIG. 4), the material (40) is placed on the upper edges (44) of the inlet runners (34) and (36) in order to then automatically move to the bending device (18 ) slip into an existing working channel. This is shown in FIG.
  • the teaching according to the invention consequently enables simple loading and unloading of rod material to be machined to and from a processing machine with structurally simple means without the loading and unloading being accomplished by independent devices. Since, furthermore, the arms (24) and (26), which allow the loading and unloading to extend rigidly from the shaft (28), are connected to the processing machine (16), this can be moved without any problem, with the shaft (28) and so that the arms (24) and (26) take place. However, these can also be moved relative to the processing machine (16) in order to grasp the bar material (10) in such a way that bending does not occur. This is particularly important if the rod material is to be processed simultaneously by several processing machines that are aligned with one another.
  • the displaceability of the shaft (28) with the arms (24) and (26) rigidly connected to it results from FIG. 1 by the solid or dashed representation, which itself is not provided with reference numerals.
