Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic workpiece transport device that automatically moves a workpiece from one processing machine to another.

Conventionally, this type of automatic feeding device has been designed to be movable, for example, on the floor of a large-scale company or factory where VC*a is connected between relatively distant processing machines. For example, the automatic transport device itself is mounted on a truck, and this truck moves on rails laid on the factory floor. When replacing various components of a processing machine, for example, metal parts when the processing machine is a press machine, the automatic feeding device itself is moved to a predetermined evacuation position between the processing machines, either in front or at the rear. The machine is moved horizontally to create a working space between the processing machines for replacing the parts. This is because it is difficult to secure sufficient space around the processing machine for rounding and replacing parts in the limited space within the factory.

However, in this way, KTh within the nine factories,
It was difficult to secure a special evacuation place for the automatic feeding device in front or behind the processing machines, for example, it narrowed the passage in the factory and became a hindrance to regression], or
There were various problems that made O-Iku Kabura especially necessary for the pillars of the factory.

At Sheep, the automatic overloading device for round workpieces is installed between the processing machine and the O-a*W station so that it can be disclosed at We proposed a method that moves up and down,
The conventional OζO@tV drawback has been solved, but since the automatic feed device does not move up and down, if there are beams or obstacles such as various machines attached to these O beams in the trajectory space, the automatic feed device 1 cannot be used. There are many inconveniences, such as not being able to raise the machine to a predetermined raised position, and not being able to secure enough space between the rolling machines to exchange parts such as molds.

The present invention has been made in view of the above circumstances, and includes the main body of an automatic feeder O being equipped so as to be movable up and down in the direct line between the processing machines and rotatable in the horizontal direction. To extremely simply form a work space below which the main body of an automatic feeding device is moved to a raised position or rotated to retreat when replacing various component parts, etc. in a processing machine. In addition, if a cradle for the workpiece is installed between the processing machines,
Even between nine processing machines that are relatively far apart, the above-mentioned pedestal Gel

According to this embodiment, these processing machines 1.2 are both so-called gate-type press machines having four pillars 3 as frameworks, and one on the left side in the figure is located above the processing line. It is located at

In the figure, numerals 4 and 5 indicate the upper mold and the lower mold in both presses 1 and 2, respectively.

On the floor of the factory, a cylindrical support 6 for this automatic feed device is erected at a position intermediate between both press machines 1 and 20. A cylindrical body 45 is rotatably mounted on the outside of this support 6, and a cross-sectional path is provided on both sides of the cylindrical body 4s. Letter-shaped guide rails 7 are provided along the vertical direction. Each of these guide rails 7 is guided by seven rails having a cross section shaped like a cross section so as to be movable up and down via guide rollers 8 which hold both of the two hinge parts. Further, the top of the cylinder 45 is equipped with a winch 10 for lifting and lowering the seven lifting frames 9. This is a drum 18K which is appropriately rotated forward 4 or reversed by the driving force of the motor ls transmitted via the form reducer 1.1.

The lower end side is connected to the upper end of the lifting frame 9, and the linear connecting body 140, such as a chain or wire, is wrapped around the drum, and the drum is 180 m long! Wc11k is configured to raise and lower the elevating frame 9 according to the amount of the linear connecting body 14C) $$j caused by the rotation. Further, the upper end of the support column 6 is equipped with a rotation drive mechanism 35 for freely rotating the cylindrical body 45. This rotary drive mechanism 35#i, a motor 36, a small gear 38 directly connected to the motor 36 via a reducer 37, and a pinion 450 are fixedly installed on the upper part of the cylinder body 450, and are combined with the small gear 38. gear 39), the rotational force due to the forward or reverse rotation of the motor 36 is transferred to the small gear 38.
and the large gear 39, so that the cylindrical body 45 can be freely rotated to a predetermined rotation angle.

Note that an operation panel (not shown) for the motor 12.36 is provided behind the cylinder body 45.

A pair of guide bodies 15 whose upper portions are close to each other and which are bent inward are provided along the vertical direction on both sides of the surface of the lifting frame 90, respectively. The 7-rank portion 1 of the holding body 16 is provided between the pair of guide bodies 15.
When 7 and K match, the holding body 16 itself is guided so as to be able to move up and down. Moreover, various fluid pressure cylinders 18 are installed between the upper part of the elevating frame 9 and the upper end portion of the holder 16 (D) for vertically operating the holder 16 with respect to the elevating frame 9. ing.

The holder 16 has a horizontally symmetrical shape and is located between the two presses along the line MK connecting them. This holding body 1 (under 10 years old) has guide parts 19-IIX scattered along the horizontal direction, and
A horizontally elongated slide body 20 is supported on the O guide portion 19 so as to be movable horizontally in the horizontal direction. It is connected to a connecting body 22. The connecting body 22, the wheels 23 located on both sides of the holding body 16, and the Kuho-Me 240 wheel 2 installed in the center of the holding body 16.
5 and the auxiliary wheel 26, which is located on both sides of the wheel 250, is connected to the K1 line, and the connection fitting 210 is connected to the motor 24 as it rotates. The return movement causes the slide body 20 to slide repeatedly in the left and right directions. In addition, three sets of four vacuum suction cups 30 are installed at a total of three locations on the lower side of the slide body 20, i.e., the intermediate portion and the left and right side portions, respectively, through supports 2'l, 2B, and 29. It is supported downwards. The vacuum suction cups 30 in each set are supported symmetrically, two at the top and two at the bottom in FIG. 2, and each is connected to a vacuum generator (not shown) through a tube. Further, the respective supports 27, 28, and 29 of each set K are rotatably adjustable relative to each other in a horizontal plane, so that the suction cups 3 in each set are mutually adjustable.
0C) Deployed type - can be adjusted as appropriate depending on the shape of the workpiece W.

Left and right cradle 32 are fixed to the lower part of the elevating frame 90 via a horizontal support 31.

This pedestal 32 is provided at a position 51 so as to equally divide into three the moving distance of the workpiece between the two press machines 1.2, that is, the distance between the two lower molds 5. The rightmost pedestal 32 in the figure is equipped with a reversing device for reversing the press-formed workpiece W and performing another press process.

In the figure, reference numeral 33 denotes a round control panel for the slider 24 that drives the slide body 20, and is installed on the front side of the support base 31.

Next, I will explain the operation of the above-mentioned components.

When the device is in operation, the lifting frame 9 is in the front lowered position as shown in 111, and the holding weight 6 and the support base 31 are located below together with the lifting frame 9. The height of the pedestal 32 at this time is the lower metal l1 in both press machines 1.2.
7() so that it is the same height as 5! ! In this situation, the piston rod of the cylinder 18 retracts and the holder 1 is moved as shown in FIG.
6 is once moved to the upward movement position relative to the lifting 7 frame 9. Then, the motor 24 is operated and the slide body 20 slides to the left from the neutral position shown in No. 111, and the set O suction cup 30 on the left side is moved to the bottom metal Wi6 of the press machine L on the left side.
Located above the workpiece on the top. Thereafter, the piston rod of the cylinder 18 is extended, and the holder 16 moves downward until the suction cup 30 touches the workpiece WK*. When the suction cup comes into contact with the workpiece 1, the suction cup 30 vacuum suctions the upper part of the workpiece 1. Then, the piston rod of the cylinder 18 is retracted,
The holder 16 is again moved to the upward position relative to the lifting frame 9, as shown in FIG. At this time, suction cup 30
The workpiece is held by suction in a suspended state. Thereafter, the motor 24 is operated and the slide body 20 passes through the neutral position shown in the first V, and slides to the right.

Then, the piston rod of the cylinder 18 is operated to extend again, and the workpiece held by the suction cup 30 moves downward until it is placed on the pedestal 32 on the left side, and then the suction cup 30 is vacuum-adsorbed. will be released. Therefore, the work piece pressed by the press machine 1 on the left side is automatically moved onto the pedestal 32 on the left side by the suction cup 301C of the left side set.

By the way, since the left pedestal 32 is provided at a position that divides the distance between the lower molds 5 into three equal parts, the device repeats the above-described operation. , the workpiece on the left side O pedestal 32 is moved by the suction cup 30 of the center set onto the right side pedestal 32, and the workpiece is moved onto the right side O pedestal s3. After the workpiece is reversed, the right side 0 action O suction cup 30 is loaded, and the right side press I is sequentially moved.
12 is moved to the lower part w5.

In this way, the workpiece processed by the press l on the left side is automatically moved to the press machine 2 on the right side via the two pedestals 32 in a so-called step-less method.

Next, when replacing or maintaining/inspecting various components such as the molds 4 and 5 that are placed in the presses 1 and 2, first stop the operation of this device as described above, and then turn off the motor 12. It is activated to raise the elevating 7 frame 9 to a predetermined raised position. In this raised position, the lower surface of the support base 32 is set in advance to be at a height of approximately 2 m from the floor surface.

Therefore, the height between the presses 142 is approximately 2
Only the pillar 3 exists in the space of m, and this space is 1% of the press machine! (It can be used extremely effectively as an exchange work space for D gold 1 [4, 5, etc.).

Furthermore, -1, when there are obstacles such as beams or various types of tower machinery in the upward movement locus space of the holder 16, and it is not possible to raise the elevating 7 frame 9 to a predetermined lifting position in that state. The motor 36 is operated to rotate the small gear 38 in either forward or reverse direction, and the large gear 39 that is engaged with the small gear 38 is rotated by a predetermined angle to move the holder 16 to a predetermined position. The lifting frame 9 is raised to a predetermined raised position while avoiding obstacles.

As explained above, according to the automatic feed device for a workpiece according to the present invention, when replacing various components in a processing machine, the main body of the automatic feed device can be left as it is or while being rotated on a horizontal plane. Since it is configured to retreat to the raised position, there is an obstacle in the ascending trajectory space of the main body of the automatic overloading device, and the rise of the main body is blocked;
Even if sufficient work space cannot be secured below the main body, the main body can be raised to a predetermined raised position while avoiding the obstacles while rotating the main body in the forward or reverse direction on a horizontal plane. Therefore, sufficient work space for replacing various components can be secured below the main body of the automatic feed system, and it does not take up any of the limited floor space in the factory. , equipment inside the factory is extremely simple. In addition, since the workpiece is moved in a so-called step-feeding method, the workpiece can be moved reliably.
