DESCRIPTION:
BRIEF SUMMARY
The invention concerns a process for discontinuous pre-conveying of flat workpieces, in particular fabric pieces in superposed relationship which are to be glued together, to a subsequent conveyor, in a working cycle comprising three working steps, wherein in the course of a working cycle during the first working step when the pre-conveyor is in the stationary condition at least one workpiece is laid on the conveyor path thereof in the receiving region thereof, wherein in the second working step the pre-conveyor is set in operation and the workpiece laid thereon is moved to the subsequent conveyor, and wherein to complete said working cycle in the third working step the moved workpiece is transferred to the subsequent conveyor and the pre-conveyor is stopped again.
The invention also concerns arrangements for carrying out that process, in particular for feeding fabric pieces which are deposited one upon the other to a glueing apparatus.
Processes and arrangements for carrying such processes into effect, of the kind indicated, are known for example from DE 39 15 091 A1 and DE G 92 01 200.0. It is precisely in the situation involving feeding fabric pieces which are to be glued together, for example a cut piece of outer material and a cut piece of insertion material or interfacing material which is to be glued to the piece of outer material, that the fabric pieces which initially are only laid one above the other, hereinafter referred to as the workpiece, are transferred for glueing thereof to a continuously operating fixing press, on the entry side thereof. However, the workpieces, particularly when they are pieces of large area, can be satisfactorily laid on a conveyor belt only when the conveyor belt is stationary during the operation of laying the workpieces thereon. In other words, the workpieces which are to be glued together cannot be laid directly on the continuously advancing conveyor belt which passes the workpieces through the glueing apparatus. Therefore, for feeding the workpieces to the glueing apparatus, use is made of a pre-conveyor and an intermediate conveyor, which are arranged in succession in the direction of conveying movement, upstream of the glueing apparatus. Now, with this arrangement, when the pre-conveyor is in the stationary condition, the workpiece can be laid on the conveyor belt thereof and can then be transferred to the conveyor belt of the glueing apparatus, by way of the pre-conveyor and the intermediate conveyor. In order better to make use of the glueing apparatus, it is also possible for two intermediate conveyors to be disposed on the entry side thereof, in mutually parallel relationship. It is also possible to provide a pre-conveyor for more than one workpiece-feed working station.
This known structure for feeding workpieces to a glueing apparatus imposes arrangements which are of relatively great length in the direction of conveying movement of the workpieces and which thus afford little opportunity for adaptation to predetermined spatial factors. In addition this structure is also technically expensive because it must always make use of intermediate conveyors.
For a process of the kind described in the opening part of this specification and for arrangements for carrying such a process into effect, the object of the present invention is to provide a further configuration in which the mutual spatial arrangement of the pre-conveyor and the subsequent conveyor can be freely selected and in which moreover it is also possible to omit intermediate conveyors in the situation involving feeding workpieces to a glueing apparatus.
The invention is based on the essential realisation that extending the conveyor path of the pre-conveyor in the manner according to the invention not only permits any spatial association of the pre-conveyor and the subsequent conveyor, but it further affords the possibility that, while the workpiece which is moved on the conveyor belt of the pre-conveyor is being deposited on the conveyor belt of the subsequent conveyor, the pre-conveyor can already be
