DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a transfer device for transferring materials and products with respect to a processing machine such as a laser processing machine, and in particular to a transfer device for transferring to and from a pallet stacker pallets on which the materials and products are carried.
BACKGROUND ART
Conventionally, an automated structure or warehouse which serves as a stacker for storing pallets carrying materials or products, is known. The automated warehouse is disposed apart a certain distance from a processing machine which may be, for example, a laser processing machine. Accordingly, when the material is taken out of the automated warehouse to be processed into products by the processing machine, the material is transferred from the automated warehouse to the processing machine through a loading device. In addition, the products processed by the processing machine are transferred therefrom to the automated warehouse through a unloading device, at present.
By the way, as is mentioned above, the loading and unloading devices are demanded and arranged to be used in the prior art, for transferring the materials and products between the stacker and the processing machine, and therefore it causes a problem that relative the is required both for moving the materials from the stacker to the processing machine and for discharging the products from the processing machine to the stacker.
The object of the present invention is to provide an improved transfer device for transferring materials and products with respect to a processing machine adjacent to which a stacker is disposed, wherein pallets for carrying the materials or products are automatically passed to and discharged from the stacker as well as processing machine for relatively short time and as a result working efficiency or productivity of the processing machine is increased.
DISCLOSURE OF INVENTION
In order to attain the above-mentioned object, a transfer device of the present invention for transferring materials and products includes a pallet stacker disposed adjacent to a processing machine and having a plurality of pallet shelves; and a pallet carrying elevator for supporting and vertically moving with respect to the pallet stacker a pallet which carries the material or product, wherein the pallet carrying elevator includes a pallet supporting device (95) which for the purposes of passing and discharging the pallet with respect to the processing machine can be switched or shifted to either non-supporting condition in which the pallet is released on the processing machine, or supporting condition in which the pallet is supported on the processing machine.
This invention is configured in another example as a transfer device for transferring materials and products with respect to a processing machine, including a stacker having a plurality of shelves to and from which material or product pallets are passed and discharged; a pallet carrying elevator provided in a vertically movable manner for supporting the pallet discharged from the shelves; a holding device provided under the pallet carrying elevator, for holding and releasing a processing pallet supported on a table of the processing machine; and a work holding portion provided above the pallet carrying elevator, for holding the material and product on any pallet supported by the pallet carrying elevator.
This invention is configured in a further example as a transfer device for transferring materials and products with respect to a processing machine, including first and second stackers disposed adjacent to each other, each stacker having a plurality of pallet shelves to and from which a plurality of material or product pallets are passed and discharged; a vertically movable pallet carrying elevator extending between the first and second stackers, the pallet carrying elevator being provided with first and second pallet supporters, the first pallet supporter being able to support the material or product pallet discharged to a position corresponding to the first st
