Description

Unloading system of machine tools The present invention relates to an unloading system capable of increasing the operational stability of a machine tool. Generally, machine tools are equipped with a so-called unloading system for removing and retrieving workpieces that have been processed. A conventional unloading system consists of a bucket unit that captures and transports a workpiece discharged by an ejector, and a conveyor that transports the workpiece carried by the bucket unit to the outside. According to the prior art, a small workpiece can be positioned off-center at one end inside the bucket unit. Consequently, as the workpiece is lowered directly onto the descending end of the conveyor (the part where the conveyor belt descends by the roller), a phenomenon of sudden ejection may occur. In addition, workpieces transported by a conveyor slide down a descending chute configured at an angle and are loaded onto a loading tray. According to the prior art, not only is the angle of the descending chute fixed, but there is also a height difference between the descending chute and the loading tray, so as the workpiece descending the chute falls, it may collide strongly with workpieces already loaded, causing scratches. FIG. 1: A drawing showing the configuration of an unloading system of a machine tool according to the present invention. FIG. 2: A drawing showing a bucket unit of an unloading system of a machine tool according to the present invention. FIG. 3: A drawing showing a stopper applied to a bucket unit of an unloading system of a machine tool according to the present invention. FIG. 4: A drawing showing a loading tray of an unloading system of a machine tool according to the present invention. FIG. 5: A drawing showing the sequential operation of a bucket unit of an unloading system of a machine tool according to the present invention. FIG. 6: A drawing sequentially showing the operation of a stopper applied to a bucket unit of an unloading system of a machine tool according to the present invention. FIG. 7: A drawing showing the sequential operation of a loading tray of an unloading system of a machine tool according to the present invention. Hereinafter, specific details for implementing the present invention will be described in detail with reference to FIGS. 1 through 7. The unloading system of a machine tool according to the present invention comprises, as shown in FIG. 1, a bucket unit (20) that grasps and transports a workpiece (5) discharged by an ejector (10), a conveyor (30) that transports the workpiece (5) transported by the bucket unit (20), a descending chute (40) that allows the workpiece (5) transported by the conveyor (30) to slide down and move, and a loading tray (50) that receives and loads the workpiece (5) moved by the descending chute (40). The bucket unit (20) is configured to approach the workpiece (5) by adjusting its position and angle by the unloader (12). The bucket unit (20) comprises a left bucket (21L) and a right bucket (21R) that rotate in corresponding directions as shown in FIGS. 2 and 3, and a stopper (27) is provided in the space formed by the combination of the left bucket (21L) and the right bucket (21R) to prevent the workpiece (5) from shifting toward the front end within the space of the bucket unit (20). The stopper (27) is attached to the hinge bracket (25) to which the left bucket (21L) and the right bucket (21R) are connected, and is configured so as not to interfere with the operation of the left bucket (21L) and the right bucket (21R). Additionally, the stopper (27) may be configured so that its position is adjusted according to the size of the workpiece (5). As shown in FIG. 4, the lowering chute (40) is configured to be angle-adjustable, and the angle adjustment structure of the lowering chute (40) can be configured such that one end is rotatably connected to a wall that surrounds the front end of the conveyor (30). The above loading tray (50) is provided with an angle-adjustable support panel (51) to match the angle of the lowering chute (40). The above loading tray (50) is formed to include a barrier wall (53) surrounding the periphery of the above support panel (51), and a guide slot (53a) is formed in the barrier wall (53) of the above loading tray (50), and the above support panel (51) is configured so that its angle is adjusted by inserting a guide pin (52) provided at its tip into the guide slot (53a) and fixing it at a specific angle. It is preferable that the above-mentioned descending chute (40) and support panel (51) be made of stainless steel so that friction is minimized. The operation of the unloading system of a machine tool according to the present invention configured as described above is as follows. First, as shown in FIG. 5, the bucket unit (20) approaches the main shaft (3) to grasp and transport the workpiece (5). This proceeds in a manner where the workpiece (5) enters the area when the left bucket (21L) and the right bucket
