Description

1. "Feeding system for a machine to machine with parts

  transported by conveyors "

  The invention relates to a feeding system

  for a machine to be machined with pieces of work transported discontinuously by conveyors, for the batch transport of the workpieces, it is used in many manufacturing operations, transport trolleys driven by

  conductors or piloted by

  They can also be towed by cat-

  air carriers who deposit the pieces of

  roller conveyors or conveyor belts

  the disadvantage of using a certain base area, and in the case of a non-planned transversal transport, of constituting an obstacle on the path As a consequence, the continuous conveyors are preferably capable of being implemented in the case of a production chain, oh each machining machine always performs the same manufacturing operations and

  transmits the workpiece to the next machine.

  On the other hand, discontinuous transport systems allow

  attempt to transport the parts of a

  to be adjusted A disadvantage of the transport system

  continuous, however, is the lack of storage capacity of the workpieces in the vicinity of the machining machines, so that they can not be implemented

  that as long as the transport system is capable of

  able to operate, so in practice, only during

a workstation.

  The object of the invention is therefore to create a feeding system for machining machines, such that storage possibilities are provided near the machining machines for the workpieces.

  achieved, in accordance with the invention, in that, on the

  conveyor, are arranged storage locations

  between them and a parts handling system

  associated with the machining machine, a system of

  waiting for pieces of work The means of transport,

  for example a transport trolley, bring the pieces of

  the storage locations and removes them from these locations, while the work pieces are transferred to the machine and are taken over by the

  system for holding workpieces.

  What is new in the invention is a consequent application of the storage and

  transport, an economic hold on the parts of

  handling and a combination satisfying the differences

  your requirements for standardized storage, transfer and standby elements

  necessary storage facilities, systems can be

  my storage of more or less important pieces of work with commands programmable by memories, using

standard elements.

  The workpiece holding system may comprise a standby slot, a distribution carriage and a transfer location,

  may be partly or wholly provided with a

  support for the workpieces, the support device being able to be a dele device.

  a rotating device or an evaluation device

  The support device may also be a transport path. All devices may also be common and the support device may be movable, which is to be recommended in the case of standby locations. in one or more rows, while the rotary device is to be recommended for the handling device, in the case of a star arrangement of the machining machine with respect to the storage locations.

  put on hold is then placed in the center, between the

  machining and the location of supply or removal of the work pieces, and transmits the pieces of work of a

place to another.

  The pieces are either preposition-

  on the auxiliary means of loading or

  directly to the hold locations, or

  be brought as needed to the handling system.

  in the meantime, stored on shelves

  The hold locations and locations of

  In the case where several machines are served, the storage units can be arranged one above the other while saving space. When loading gantries are used, the standby position is equipped with a digitally controlled axis, so that the workpieces, corresponding to their position on the auxiliary loading means, are brought exactly into the position provided for in the system

Handling.

  According to another embodiment of the invention, the pieces of work can be arranged on an auxiliary loading means 9 in the form of a pallet The pieces can be prepositioned in positioning locations defined on supports, in containers, baskets, etc., provided with specific fittings of the workpiece Several units can be deposited on a standard auxiliary loading device The handling system is then able to take the parts from the different positioning locations of the workpiece. the pallet and to deposit them again after machining The pallets can

  also be moved with their posi-

  according to coordinates, so that the handling system can seize the parts always in the same location The handling system can be what is called an industrial robot that can itself be

  moved on a loading gantry.

  Several examples of realization of the invention
