Abstract

PURPOSE:To enable quick and continuous painting of a large amt. of materials to be painted by disposing an oscillation stopper which is engaged with the material conveyed by a conveyor or a hanger suspending said material and stops the oscillation thereof. CONSTITUTION:A conveyor 4 is operated to convey and supply successively a material to be painted which is suspended to a hanger 16 and when the conveyor 4 is stopped in a painting position, the material is going to oscillate in the conveying direction together with the hanger 16 owing to inertia. However, the left end of the movable piece 21 of an oscillation stopper S is retrained in the contact position of the hanger 16 with the material held still in the prescribed painting position so as to intersect orthogonally with the conveying direction of the conveyor 4 and therefore the hanger 16 engages with the piece 21 and is thus held still in the prescribed position, by which the oscillation of the material to be painted is quickly stopped. When the painting is completed in this state, the right end of the piece 21 is depressed downward and is disengaged from the hanger 16.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides continuous coating by a coating machine attached to an automatically controlled manipulator for objects to be coated that are suspended and conveyed from a plurality of hangers arranged at predetermined intervals on a conveyor. The present invention relates to a swing stop device for an object to be painted in an automatic painting device.

2. Description of the Related Art Automatic coating apparatuses have rapidly become popular in recent years in order to streamline coating and save labor, and are particularly used when continuously coating large quantities of objects having uneven shapes.

Figure 1 is an overall diagram showing an example of the automatic painting equipment.
In the figure, 1 is a manipulator, 2 is an automatic coating machine attached to the manipulator 1, 3 is a control panel for automatically controlling the manipulator 1, and 4 is a conveyor for conveying objects to be coated to be loaded onto a workpiece 5.

The manipulator 1 uses a hydraulic cylinder (not shown) disposed in a base 6 to rotate a base 9 on which a horizontal arm 7 and a vertical arm 8 are mounted left and right, and also operates a cylinder 10 to rotate the horizontal arm 7. , operate the cylinder 11 to rotate the vertical arm 8, and further rotate the horizontal rotation hydraulic motor 12 and the vertical rotation hydraulic motor 13 to which the automatic coating m2 is attached, to obtain the desired automatic coating machine 2. It is designed so that it can be operated freely within the range of movement of the person.

The conveyor 4 consists of a conveyor rail 14 and a plurality of trolley parts 15 running on the rail 14.
5 has a hook 15a fixed to it. The flap 1 of this trolley part 15. 15a & kobanma, hook part 1 on both ends
A nozzle 16 having 6a and 16b is hooked, and a workpiece 5 carrying objects to be coated is suspended from the lower end of the nozzle.

The conveyor 4 carries each workpiece 5 loaded with objects to be coated.
It is configured such that its operation is stopped each time it is sequentially conveyed and supplied to a predetermined coating position facing the manipulator 1.

The control panel 3 instructs the flow-nobby device 18 to perform predetermined operations of the manipulator 1 and the automatic coating machine 2 in order to automatically perform a desired coating operation on the object to be coated that is transported to the coating work area by the conveyor 3. This system controls the manipulator 1 and the automatic coating machine 2 so that the paint is stored in the floppy disk provided and the paint is discharged according to the stored data, and the object to be painted is transported and supplied to the painting work area facing the manipulator 1. , each time the manipulator 1 is stopped at a predetermined position to be coated, the same operation is repeated, and the automatic coating machine 2 turns on and off the paint as instructed, thereby applying the paint to a complex-shaped object with uneven surfaces. Uniform coating is automatically applied even to surfaces.

However, in such an automatic coating device, the objects to be coated that are intermittently conveyed and supplied by the conveyor 4 are stopped one by one at a predetermined position to be coated, and the objects to be coated suspended on the hanger 16 are stopped. Painting must begin in a completely still position.

The sprayer, manipulator 1 and automatic coating machine 2 are controlled by g
Since the control is simply to repeatedly execute a series of operations recorded on the floppy disk in the floppy device 18 of the i13 as instructed, the conveyor 4 is used to suspend the object to be coated at a predetermined position to be coated. This is because the object to be coated cannot be coated uniformly unless it is stopped at a predetermined position and at the same time the object to be painted suspended by the hanger 16 is kept completely still.

However, as shown in Fig. 2, when the conveyor 4 is stopped when the workpiece 5 loaded with objects to be coated reaches the predetermined position to be coated, the workpiece 5 is suspended from the carrier 16 due to inertia. The workpiece 5 oscillates in the conveyance direction of the container 4 together with the /'1 ringer 16, and therefore a very long waiting time is required until this oscillation condition naturally subsides and the workpiece 5 comes to a complete standstill at the predetermined position to be coated. However, it had the serious drawback of not being able to perform rapid automatic painting.

Therefore, the present invention provides a device for stopping the swinging of the object to be coated in an automatic painting apparatus, which quickly stops the swinging object being transported to a predetermined position to be coated and enables rapid continuous painting of a large amount. The purpose is to

In order to achieve this object, the present invention applies to objects to be coated that are suspended from hangers of a conveyor that is operated intermittently, are sequentially conveyed and supplied to a predetermined painting work area, and are kept stationary at a predetermined position to be coated. A swing stop device for an object to be coated in an automatic coating apparatus configured to automatically perform coating by a coating machine attached to a manipulator, wherein the object to be coated is conveyed and supplied by the conveyor and shaken at the position to be coated. The present invention is characterized in that it has a swinging stop that engages with a moving object to be coated or a hanger for suspending the object to be coated, thereby stopping the object to be coated at the position to be coated.

Hereinafter, the present invention will be explained based on specific embodiments shown in the drawings.

FIG. 3 is a side view showing an example of the device for stopping the swinging of an object to be coated according to the present invention, and FIG. 4 is a perspective view showing the main parts thereof.

The swing stop device S includes a base 20, a support 22 that is fixed to the lower end of the base 20 and rotatably supports a movable piece 21 serving as a swing stopper, and a support 22 that is also attached to the lower end of the base 20. It is composed of a cylinder 23 which is fixedly installed and rotates the movable piece 21 up and down.

The support body 22 has two substantially trapezoidal side plates 24 and 25 that are arranged facing each other with a distance corresponding to the thickness of the movable piece 21, and a bottom plate 26 that connects the side plates 24 and 25 is fixed to the lower left end in the figure. At the same time, a rotating shaft 27 that rotatably supports the movable piece 21 is provided through the right corner.

The movable piece 21 is made of a steel plate or the like, and is attached to the side plate 2 of the support body 22 so that both ends thereof protrude from the support body 22 by a predetermined length.
4 and 25, and is rotatably supported by a rotating shaft 27, and a long slot 28 is formed in the longitudinal direction at the protruding right end.
is drilled.

A U-shaped connecting fitting 30 is fixed to the rod head 29 of the cylinder 23, and the connecting fitting 30 is slidably engaged in the long groove hole 28 of the movable piece 21.

The swing stop device S configured as described above is transported to a predetermined painting work area by a conveyor 4 consisting of an I-shaped steel conveyor rail 14 and a trolley part 15 running on the rail 14, as shown in FIG. It is installed near a predetermined painting position where the supplied workpieces are automatically coated, and is installed, for example, on the ceiling of the painting room above the painting position, or on a column or support stand of the conveyor 4 (not shown). A support base 20 is fixedly installed and hangs down from above.

Then, the conveyor 4 is operated to convey and supply the object to be coated suspended from the hanger 16 to a predetermined coating work area, and when the object to be coated reaches the predetermined position to be coated, the conveyor 4 is operated. make it stop.

At this time, the object to be coated suspended on the conveyor 4 does not swing together with the hanger 16 in the transport direction of the conveyor 4 due to inertia. Since the left end of the movable piece 21 of the swing stop device S is held at the position where it abuts the movable piece 21 perpendicular to the conveyance direction of the conveyor 4, the hanger 16 is engaged with the movable piece 21 and held at a predetermined position. The object to be coated is brought to a standstill, and the swinging of the object to be coated is immediately stopped.

After the object to be coated is stopped at a predetermined position to be coated and the predetermined coating is completed by the automatic coating machine 2 attached to the manipulator 1, the object to be coated is suspended above the position to be coated as shown by the chain line in FIG. The installed swing stop device S is activated to extend the piston rod 31 of the cylinder 23, and the connecting metal 30 fixed at the tip of the rod head 29 is moved to the movable piece 2.
1 by sliding in the long slot 28 of the movable piece 21 and pushing down the right end of the movable piece 21, the left end of the movable piece 21 is pushed upward and the engagement between the hanger 16 and the movable piece 21 is released,
The conveyor 4 is operated again to carry out the object to be painted and at the same time convey and supply a new object to the painting work area.

At the same time as this object to be coated is carried out, the cylinder 23 of the swing stop device S is operated in the opposite direction to the previous one to contract the piston rod 31, pull up the right end of the movable piece 21, and return the left end to its original position. and stop the swinging of the new object to be coated.

Each operation of the swing stop device S as described above can be performed by connecting the swing stop device S to the control panel 3 shown in FIG. The control may be performed in response to the operation of the .

As described above, according to this embodiment, the swing stop device S is used for the hanger 16 that is transported to a predetermined position to be coated by the conveyor 4 and is not to swing together with the object to be coated when the conveyor 4 stops transporting. Since the movable piece 21 engages and stops its swinging, the object to be coated can be quickly stopped at a predetermined position to be coated, and therefore, there is an excellent effect that a large amount of continuous coating can be quickly performed. .

In particular, the swing stop device S shown in this embodiment has its support base 20
Since it is fixed to the ceiling of the painting room and suspended from above, it does not take up much space and has the advantage of avoiding adhesion of paint particles.

Furthermore, since the movable piece 21 is slidably held by the side plates 24 and 25 of the support body 22, it can move back and forth accurately to the position where it contacts the hanger 6 when the object to be coated is stationary at a predetermined position to be coated. It also has the advantage of being strong against impact when it hits the hanger 6.

The movable piece 21 can be cushioned by inserting a spring material such as a leaf spring 40 at its left end as shown in the diagram, and by forming its tip at an acute angle, the movable piece 21 can be prevented from swinging. It can be easily engaged with a moving hanger.

Further, the swing stop device according to the present invention is not limited to the above structure, and may have a structure installed on the floor or a wall, and the swing stop device may also be one that engages with a hanger for suspending the object to be coated. However, the structure is not limited to this, and may have a structure that directly engages with the object to be coated to stop its swinging.

As described above, the present invention engages with the swinging workpiece that is sequentially conveyed to a predetermined painting work area by a conveyor that is operated intermittently, or the hanger that suspends the workpiece, thereby suppressing the swinging of the workpiece. This is a swing stop device that has a swing stop device that stops the object to be coated and quickly stops the object to be coated at a predetermined position, so if it is installed in an automatic coating device, it can perform extremely rapid continuous coating in large quantities. This has an excellent effect.
