The product G is loaded from the suction pad 95 onto the product pallet P _G by extending the piston rod 91 by the operation of the vertically moving cylinder 87 at the discharge position and guiding the suction frame 93 downward by the guide 89. become.

On the front side of the upper table 13 in the press brake 3, a tilting table 105 for loading as a work receiving table member is provided so as to be rotatable by a rotating shaft 103. As a means for turning the loading tilt table 105, for example, a turning motor 103 (not shown) may be used to rotate the turning shaft 103, and the loading tilt table 10 may be rotated.
Alternatively, one end of 5 may be tilted by vertically moving it by a cylinder or the like.

In the upper part between the support frames 83, the swing shaft 10 rotatably supported by a frame (not shown).

In this state, the loading tilt table 1
05, by tilting the tilting table 109 as shown in FIG. 1, the product G on the loading tilting table 105 slides by its own weight and is transferred onto the tilting table 109. The tilt table 109 is kept horizontal and the work transfer means 84 causes the products G to be loaded on the product pallet P _G.

Therefore, since the work is transferred from the loading device 7 to the press brake 3 by the work transfer means 57,
Tact time can be shortened as compared with the conventional one, and the transfer can be performed. Similarly, since the loading tilting table 105 and the tilting table 109 are provided so as to be switchable between the horizontal state and the tilted state, the processed product can be easily transferred to the unloading device 9 side, and the takt time is longer than that of the conventional one. It can be shortened.

Since the work transfer means 57 is constituted by a simple device rather than a large-scale device such as the conventional supply robot, a large cost reduction can be achieved.

In the above embodiment, the loading tilting table 105 and the tilting table 109 are independently provided so as to be separable and tiltable, so that the work W and the product G can be easily loaded and unloaded. However, the loading tilting table 105 and the tilting table 109 can be integrated.

As shown in FIG. 5, when performing step bending on the work W by the punch P of the press brake 3 and the die D, the tilt table 105 for loading is placed at a position corresponding to each punch P. For example, the work W transferred from the loading device 7 is provided to the stopper 11 by providing a stopper 115 that can be retracted or swung freely.
Since it is positioned by abutting against 5, the work W can be easily bent.

Another embodiment for vertically transferring the work W from the loading device 7 to the press brake 3 is shown in FIGS. 6, 7 and 8. That is, in FIG. 6, FIG. 7, and FIG. 8, the same parts as those in the above-described embodiment are designated by the same reference numerals, and the duplicated description will be omitted. 6 and 7, as the loading device 7, a transfer device 117 is provided above the material pallet P _W to change the work W from the horizontal state to the vertical state.

An upper end of a vacuum pad 143 is provided on each shaft 141.

With the above structure, when the rotation cylinder 133 is operated, the piston rod 135 is expanded and contracted in FIG. Since the arm member 139 swings via the rod 137 due to the expansion and contraction of the piston rod 135,
The vacuum pad 143 is positioned via the shaft 141 in a vertical state indicated by a solid line and a horizontal state indicated by a two-dot chain line.

Therefore, the vacuum pad 143 is lowered to attract the uppermost work W among the works W loaded on the material pallet P _W and then raise it. Then, the work W is held in the vertical state by positioning the vacuum pad 143 in the horizontal state.

In FIG. 8, since it is moved in the direction orthogonal to the paper surface, the clamper 149 is also moved in the same direction.

Therefore, the uppermost work W among the works W loaded on the material pallet P _G is lifted in the horizontal state by the vacuum pad 143, and then the vacuum pad 143 is rotated 90 degrees. Held vertically by In this state, the work W is transferred from the vacuum pad 143 to the clamper 149. Then, by moving the clamper 149 to the press brake 3 side, as shown in FIG.
It is positioned on the front side of the upper table 13 above the processing position.

Thus, the work W can be vertically transferred from the loading device 7 to the press brake 3 side while shortening the tact time.

As shown in FIG. 8, since a work sink 157 as a work receiving table member is provided on the front side of the upper table 13, the upper table 13 is provided.
The workpiece W transferred and positioned by the clamper 149 to the front side of the workpiece W is dropped to the workpiece sink 157 by unclamping the clamper 149, and the workpiece sink 157.
Will be placed on top.

The work W placed on the work sink 157 is the robot hand 41 of the handling robot 5.

According to the invention of claim 4, the work receiving table member is provided on the upper table or the lower table in the plate material processing machine, and the work receiving table member is extended to the unloading device provided adjacent to the plate material processing machine. Therefore, the work processed by the plate material processing machine can be transferred from the work receiving table member to the unloading device.

According to the invention of claim 5, since the work receiving table member is rotatably provided and the handling robot is provided in front of the plate processing machine, the work on the work receiving table member is handled. By setting the work receiving table member in a horizontal state when supplying the work to the robot, the work can be easily supplied from the work receiving table member to the handling robot. Further, when the processed work on the work receiving table member is conveyed to the unloading device, the work can be easily and smoothly transferred by tilting the work receiving table member.

According to the sixth aspect of the invention, the work receiving table member is provided in the plate material processing machine region and the unloading device region so as to be separable from each other, and the separated work parts are independently rotated in a horizontal state or an inclined state. Since it is movably provided, the work can be easily carried out when the work is received by the work receiving table member from the loading device.
Further, when the processed work is transferred from the work receiving table member to the unloading device, the work can be transferred smoothly.

According to the seventh aspect of the present invention, since the work receiving table member is provided with the positionable work stopper for positioning the work at each processing station in the plate material processing machine area, it has been transferred by the work transfer means. After the work slides on the work receiving table member and is stopped and positioned by each work stopper, the plate material can be processed.

According to the invention of claim 8, a loading device and an unloading device are respectively provided adjacent to both sides of the plate material processing machine, and the upper table or the lower table of the plate material processing machine is provided with one of the front side and the rear side. The first to transfer the work from the loading device to the plate processing machine side
A work transfer means is provided, and a second work transfer means is provided on the other of the upper table and the lower table and is movable from a plate material processing machine or a handling robot provided in front of the plate material processing machine to a unloading device side. Therefore, the work can be transferred from the loading device to the upper table or the lower table in the plate material processing machine by the first transfer means. Further, the work processed by the second work transfer means can be transferred to the unrotating device.

According to the invention of claim 9, the first work transfer means is a conveyor, and the second work transfer means is a rotatable and telescopic transfer device having a work suction portion at the lower end. The transfer can be performed more reliably.
