Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention mainly relates to a reversing device used in a production process of products such as kitchen units.

[Prior Art] Conventionally, the reversing work of a product such as a kitchen unit for hitting a nailer or a tacker has relied solely on human labor.

[Problems to be solved by the device]

There has been a problem in that the burden on the worker is large when the manual work is performed as in the past.

An object of the present invention is to provide a reversing device that can efficiently invert a product.

[Means for Solving the Problems]

The reversing device of the present invention is provided with a horizontal frame supported by a vertical frame so as to be able to move up and down, and a suction pad capable of holding a product at the tip of a rotatable cylinder rod that is horizontally opposed to the horizontal frame. A pair of extruding cylinders, a holding width adjusting mechanism capable of moving one of the extruding cylinders in the axial direction, and a cylinder rod attached to the proximal end side of the cylinder rod of the other extruding cylinder are required. And a stopper mechanism that can hold the rotation angle of.

[Action]

According to the configuration of this invention, the product can be inverted without using human hands, the work efficiency is improved, and the product can be temporarily floated in the air and inverted on the spot. It takes less time. Further, the cylinder rods of the pair of extrusion cylinders can be moved back and forth, and one of the extrusion cylinders itself can be moved back and forth by the holding width adjusting mechanism. Therefore, by adjusting the position of one extrusion cylinder in advance so that the product enters between the suction pads facing each other according to the size of the product, the stroke of the cylinder rod when holding the product can be reduced. Can be shortened. Further, since the holding width adjusting mechanism is provided in this way, the shape of the product can be adapted to exceed the stroke of the cylinder rod, and the extrusion cylinder may have a short stroke.

Further, since the stopper mechanism capable of holding the rotation angle of the product is provided only on the other extruding cylinder, the structure is simplified. Since the holding width adjusting mechanism is provided on one of the extruding cylinders as described above, the function is shared by both the pair of extruding cylinders and the ratio is designed without waste.

〔Example〕

1 to 3 show an embodiment of the present invention. This reversing device holds a product 1 such as a kitchen unit by a holding mechanism 2 composed of a pair of extrusion cylinders 18, lifts the holding mechanism 2 holding the product 1 vertically by a lifting mechanism 3, and The inversion mechanism 4 rotates the holding mechanism 2 to invert the product 1.

Reference numeral 15 is a base of the reversing device, and the vertical frame 5 is erected on the base 15. The holding mechanism 2 is attached to the vertical frame 5, and a horizontal frame 6 attached to the vertical frame 5, and a pair of left and right hydraulic / pneumatic extrusion cylinders 18 attached to the horizontal frame 6 via brackets 7. It consists of and. The cylinder rod axes of the left and right extrusion cylinders 18 are located on the same horizontal line. One extruding cylinder 18 is brought close to or away from the other extruding cylinder 18 by the holding width adjusting mechanism 8 so that the distance between the extruding cylinders 18 can be adjusted so as to correspond to the width of the product 1. The holding width adjusting mechanism 8 is configured such that one bracket 7 can be moved to the left and right along the guide 11 of the horizontal frame 6 by driving the positioning ball screw 9 in the normal and reverse directions.
A suction pad 12 is attached to the tip of the cylinder rod 10 of the extrusion cylinder 18. The suction pad 12 is connected to a vacuum pump (not shown) so that the suction surface of the suction pad 12 holds the product 1 in a vacuum state.

The lifting mechanism 3 moves the horizontal frame 6 up and down along the guide 14 of the vertical frame 5 by means of the hydraulic / pneumatic cylinder 13.

Reference numeral 16 denotes an advancing / retreating mechanism that advances and retracts the reversing device toward the product 1 along the guide rail 25 by the hydraulic / pneumatic cylinder 17.

The reversal mechanism 4 is a mechanism for reversing the product 1 by manually rotating the cylinder rods 10 of the left and right extruding cylinders 18 about the axis, and the product 1 can also be rotated 360 degrees by the stopper mechanism 19. Can be held at the required rotation angle. The stopper mechanism 19 is provided on one extruding cylinder 18
The base end of the cylinder rod 10 is composed of a gear 20 attached to a crocodile and a stopper cylinder 21, and the tip 23 of the cylinder rod 22 of the stopper cylinder 21 is locked in the valley of the gear 20 to rotate the gear 20. Is stopped, and the required rotation angle of the product 1 is maintained. The reversing mechanism 4 may be automated.

FIG. 2 illustrates the operation of the reversing device. First, the reversing device is advanced so that the extrusion cylinder 18 is positioned above the transport roller 24 with respect to the product 1 which has been transported by the transport roller 24 and stopped as shown in FIG. Next, as shown in Fig. 2B, the cylinder rods of the left and right extrusion cylinders 18
10 is pushed out and both sides of product 1 are sandwiched and suction pad 12
Adsorb and hold the product 1. Next, as shown in FIG. 3C, the product 1 is moved by the hydraulic / pneumatic cylinder 13 of the lifting mechanism 3.
After lifting, the product 1 is inverted by the inversion mechanism 4. FIG. 4 shows a base cabinet stove as a product 1. The base cabinet stove 1a is inverted and the nailer and the tacker are struck on the front plate 1b, the back plate 1b, the top plate 1c and the bottom plate 1d. After the work is completed, the operation opposite to the above operation is performed and the holding posture of the next product 1 is taken.

[Effect of device]

According to the reversing device of the present invention, a holding mechanism for holding a product such as a kitchen unit, a lifting mechanism for lifting the holding mechanism for holding the product, and a product lifted by rotating the holding mechanism. Since it has a reversing mechanism for reversing, the product can be reversed without using human hands, the work efficiency is improved, and the product can be temporarily floated in the air and then reversed on the spot. Also, the reversing time is short, and the working efficiency can be further improved. Further, the cylinder rods of the pair of extrusion cylinders can be moved back and forth, and one of the extrusion cylinders itself can be moved back and forth by the holding width adjusting mechanism. Therefore, by adjusting the position of one extrusion cylinder in advance so that the product enters between the suction pads facing each other according to the size of the product, the stroke of the cylinder rod when holding the product can be reduced. Can be shortened. Therefore, even if the size of the product is changed, the operating time for the cylinder rod to move back and forth does not become long, which is effective in mass production and the productivity can be improved. Further, since the holding width adjusting mechanism is provided in this way, there is an advantage that the shape of the product can be adapted to exceed the stroke of the cylinder rod, and the extrusion cylinder may have a short stroke.

Further, since the stopper mechanism capable of holding the rotation angle of the product is provided only on the other extruding cylinder, the structure is simplified. Since the holding width adjusting mechanism is provided on one of the extruding cylinders as described above, it can be said that the function is shared by both of the pair of extruding cylinders, and the design is rational without waste.
