Description

[Detailed Description of the Invention] The present invention relates to a work stacking device that automatically stacks several types of small rectangular parallelepiped works in a predetermined order at high speed and with high precision.

Conventionally, this type of work has been difficult to handle because the workpieces have been piled up manually due to their small size, and the work has been slow and inefficient due to the use of tweezers and the like. In addition, the dust removal function was incomplete due to manual handling, and the stacking accuracy varied depending on the operator.

In view of this, the main purpose of the present invention is to propose a high-speed, high-precision stacking device that improves efficiency by automating the handling of workpieces.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic perspective view showing an example of the present invention. First, reference numeral 1 indicates several conveyors for conveying workpieces, and an L-shaped positioning guide 2 for conveying workpieces provided on the upper surface of the conveyor 1 moves the workpieces 3 being conveyed while restricting the width direction to a positioning stopper 4. It is configured to be transported. The movable cart 7 is controlled to stop at a position above each workpiece 3 stopped by the guide 2, and is configured to move on the rail 9. The truck 7 is provided with a cylinder 6 for raising and lowering, and the cylinder 6 is also provided with a vacuum suction section 10 for suctioning the workpiece 3.

As shown in FIG. 2, the suction unit 10 can suction the workpiece 3 using the suction air nozzle 5 and can be raised using the upper and lower cylinders 6. The upper and lower surfaces of the attracted workpiece 3 are cleaned by air blowing nozzles 15 and 16 for removing dust. Reference numeral 21 indicates an adsorption exhaust conduit, which is provided to connect the main body and the nozzle 5. Also, on the left and right sides of the conduit 21, there are suction parts 1 when the workpiece 3 is suctioned.
Absorber 2 that absorbs the dimensional difference when the entire 0 falls
2 is provided. The absorber 22 has a spindle 23 fixed on one side and a spring 24 wound around the spindle 23.
It is made up of.

Referring again to FIG. 1, reference numeral 13 indicates a setting table on which the cart 7 moves to the other end of the rail 9 (on the left side in the figure) and sequentially stacks the workpieces. When stacking the work 3 on top of this, in order to ensure that the stacked position of the work 3 is always on the top surface of the previous work 3, the top surface level of the work 3 is detected by the sensor 12 as shown in FIG. , and is controlled by a lifting device 20 (see FIG. 1). The lifting device 20 can be composed of a rack, a pinion, or the like. Incidentally, the end faces of the stopper 4 and the setting table 13 of the lifting device 20 are set so as to coincide with each other, as shown in FIG.

In this case, the movement procedure of the cart 7 when going to pick up the workpieces 3 follows the stacking pattern of the workpieces 3. Since the movement of the trolley 7 is numerically controlled by a linear pulse motor, as shown in FIG.
For example, works 3 with different compositions are placed on each conveyor 1.
By arranging the workpieces 3 and setting the distances to the take-out positions of the workpieces 3 as A, B, and C in advance, it is possible to arbitrarily set the stacking pattern of the workpieces 3 at high speed and with high precision.

As described above, according to the present invention, a plurality of conveyors each convey several types of cubic workpieces, and dust removal air is blown to remove dust from the upper and lower surfaces of the workpieces, which are positioned at the stopper at the end of the conveyor. It consists of a device, a suction unit that moves up and down for attaching and detaching the workpieces, and a moving cart that moves back and forth between a position where a jig for stacking the workpieces is arranged and several conveyor positions and has the suction unit. By controlling the moving cart, the stacking pattern of the workpieces can be arbitrarily set, making it possible to actively remove dust during the transport process, and to clean various workpieces that require cleaning at high speed and with high precision. can be transported to Also, according to the present invention,
Even if workpieces with different compositions are automatically supplied,
By setting a stacking pattern of a certain composition in advance, it has the effect of automatically stacking them in a free stacking state.
