Then a prearranged amount of clear paint is injected from a paint jet nozzle 7 provided on the painting position 9b applying the metal plate 9.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to, for example, when several to several tens of long products such as steel pipes and steel bars are bundled together as one unit. Related to a device that prints accompanying information (manufacturer name, ordered pitch name, length, weight, etc.) on a metal plate and loads the printed metal plate into a binding machine in order to automatically attach it to the product together with the binding band. .

[Prior art]

Long steel products such as steel pipes and bars go through an inspection process after the manufacturing process, and are classified by orderer, length, and outer diameter, grouped into units of several to dozens, and placed at several locations along the length. The products are bound by a binding machine and then shipped or stored.

At the time of binding, a metal plate on which information associated with the product, such as the manufacturer's name, ordered pitch name, length, and quantity, is printed is attached to the product together with the binding band in the binding machine.

This metal plate has different orders! i! There are various types depending on the type of product, and conventionally, printing is mounted as shown below. In other words, an outside specialist performs anti-corrosion treatment on one side of a metal plate treated with chromic acid, presses it into a predetermined size and shape, and prints off-cent prints on the anti-rust side. ,
Using a printing method such as screen printing, fixed information such as a manufacturer's name, an ordered note name, two patterns, etc. whose contents are common to each product is printed and fixed, and the products are printed and delivered to a binding place.

After that, the worker reads the variation information, which varies from product to product, such as product length, weight, etc., from the inspection process and sends it to the computer that stores it, and outputs it from the computer's CRT or printer. Visually check and transcribe by hand or stamp in the appropriate column on the metal plate. The metal plate printed in this way is loaded into the metal plate loading position of the binding machine by hand by an operator. After that, the binding machine attaches the metal plate together with the binding band to the product by inserting the banding band into the two holes formed at both ends of the loaded metal plate and winding the banding band around the product. let

[Problem that the invention seeks to solve]

With conventional printing and loading equipment for metal plates, the printing of fixed information is outsourced to an external specialist company, so it takes four days to a week from ordering to delivery, which means that it cannot be done in time for emergencies. There were cases where the product had to be packaged without the metal plate attached, and there was the inconvenience of having to reattach the metal plate after it was delivered.

Furthermore, since the fluctuation information is printed by handwriting or stamping, and because the printed metal plate is loaded into the binding machine by hand, there is a problem of low work efficiency. In addition, when handwritten letters are printed, the printed letters may disappear due to friction caused by the worker's hands or clothes during loading into the binding machine or during subsequent work. .

[Means for solving problems]

The present invention has been made in view of the above circumstances, and uses a high-energy beam printing device to print fixed information, which was conventionally outsourced to an outside specialist, and to transcribe variable information, which had to be done manually by an operator.

The suction plate main body 56h is fixed to the tip of the slide arm 54 at the position of the sliding rod 56a via four coil springs 56b.

A suction hole 56c is passed through the center of the suction surface of the suction plate main body 56h from the suction surface side toward the back surface thereof, and one end of the air hose 56d is connected to the connecting member 56 through the suction hole 56c.
The other end of the air hose 56d is connected to a vacuum pump (not shown).

A recess 56f is formed on the suction surface side of the suction plate main body 56h, with the suction hole 56c as the center. Further, a sponge cushioning body 56g is attached to the suction surface of the suction plate main body 56i.

Both ends in the longitudinal direction of the slide arm 54 on the suction surface of the suction plate main body 56h have an arcuate cross-sectional shape as shown in FIG. This is to serve as a guide for warping the metal plate 9 into an arc shape according to the shape of the metal plate holder 10 when the metal plate 9 is mounted on the metal plate holder 10. It is not necessary to have such a shape.

Regarding other parts, the suction plates 54 and 43 have the same structure as the suction plate 56.

Now, the operation of the printing plate printing device according to the present invention configured as described above will be explained. FIG. 5, FIG. 6, FIG. 7, and FIG. 8 are explanatory diagrams of the operation of the manipulator 5. First, the metal plate conveyance arm 4 is in the position shown in FIG. 1, with the suction plate 43 positioned above the center of a large number of metal plates 9 stacked on the metal plate mounting table 3.

Furthermore, the slide arms 53 and 54 of the manipulator 5 are positioned as shown in FIG.
are located at the lowest part of the manipulator body 51, and the suction plate 55 is located above the center of the coating position 9b.

First, the suction plate support rod 42 slides down with respect to the support rod holder 41, and the suction plate Fi 43 is brought into contact with the top surface of one of the internally placed upper parts of the metal plates 9 stacked on the metal plate holder 3. Stop. Thereafter, the metal plate 9 is sucked by the suction action of the suction plate 43, and the suction plate support rod 42 slides upward relative to the support rod holder 41, and the metal plate 9 is attached to the tip of the frame member 32 and the top surface of the table 2. lift to a higher position.

At the same time, the metal plate transfer arm 4 moves clockwise 9 when viewed from above.
The metal plate 9 is rotated by 0° and the metal plate 9 adsorbed on the adsorption plate 43 is conveyed directly above the printing position 9a. Thereafter, the support rod 42 is lowered to lower the metal plate 9 until it comes into contact with the upper surface of the table 2, and the suction of the suction plate 43 is released to properly place the metal plate 9 on the printing position 9a. At this time, the metal plate transfer arm 4 rotates 90 degrees and transfers the metal plate 9, so that the metal plate 9 is rotated around its central axis from the state where it was stacked on the metal plate placement table 3. The metal plate 9 is rotated by 90 degrees, that is, its longitudinal direction is perpendicular to the longitudinal direction of the table 2.
The table 2 is placed on the printing position 9a with the longitudinal direction of the long hole 91 formed along the short side of the table 2 aligned with the longitudinal direction of the table 2.

Thereafter, the support rod 42 rises with the metal plate 9 placed on the table 2, and the metal plate transfer arm 4 rotates 90 degrees counterclockwise when viewed from above, moving the suction plate 43 to the metal plate holder. 3
It is positioned above the center of the metal plate 9 which is placed above and stopped, that is, it returns to its initial state.

The metal plate conveyance arm 4 repeats the above operation to sequentially convey the metal plates 9 on the metal plate placement table 3 to the printing position 9a, but at this time, the number of metal plates remaining on the metal plate placement table 3 decreases. As the stacking height of the metal plates 9 decreases, the stacking height of the metal plates 9 is lowered, so that it does not fall outside the range of the vertical stroke of the support rod 42.
Every time a predetermined number of metal plates are transferred by the metal plate transfer arm 4, the metal plate pusher 31 is raised by a predetermined amount, so that the top surface of the stacked metal plates 9 is always positioned near the upper end of the frame member 32. It is made to be.

After the metal plate 9 is placed on the printing position 9a and the metal plate conveying arm 4 rotates and retreats from above the printing position 9a, the laser oscillator 61 of the laser printing device 6 installed above the printing position 9a A high energy laser beam 62 is oscillated.

The laser beam 62 is directed to the metal plate placed on the printing position 9a by rotating the pulse motors 64a, 65a and changing the angles of the reflecting mirrors 64, 65 in response to a control signal output from the computer 66. The entire top surface of the metal plate 9 is scanned, the top surface of the metal plate 9 is melted and vaporized, and a pattern is imprinted on the metal plate 9 by the traces.

The amount of rotation of the pulse motors 64a+65a is controlled by control signals output from the computer 66 in accordance with required print information input from the host computers 67, 68.

In a position where printing is not required, the electromagnetic actuator 63a is operated by a control signal output from the computer 66, the shutter 63 is closed, and the laser beam 62 is directed to the reflecting mirror 63.
Shut off before reaching 4.

In this way, the opening and closing of the shutter 63 and the reflecting mirrors 64 and 65
By continuously performing the rotation □, the required print information is transferred onto the metal plate 9 placed on the print position 9a.

After the printing work on the metal plate 9 above the printing position 9a is completed,
The manipulator 5 moves in the longitudinal direction of the table 2 to approach the metal plate stand 3 by rotating the feed screw 81, and the support rod 5 moves toward the limit switch 83 provided in the groove 8.
It stops when 2 comes into contact with it. During this movement, the slide arm 53 moves above the table 2 at an appropriate distance, and the suction plate 55 stops at a position above the center of the printing position 9a.

Furthermore, the slide arm 54 is connected to the metal plate stand 3 of the table 2.
From the end opposite to , it passes through the lower part of the table 2 and stops immediately below the notch 21 . The state at that time is shown in FIG. Thereafter, the slide arm 53 descends along the side surface of the two tables of the manipulator body 51, and stops when the suction plate 55 comes into contact with the metal plate 9 placed on the printing position 9a from the printing surface side. .

This metal plate 9 is painted at the painting position 9b as explained below, but the previously painted metal plate 9 is painted at the painting position 9b.
The following explanation will be given assuming that it is placed above.

Simultaneously with the lowering of the slide arm 53, the slide arm 54 rises along the side surface of the manipulator main body 51 on the table 2 side, and adsorbs the metal plate 9 placed on the coating position 9b from the side opposite to the coating surface. It comes into contact with the plate 56 and stops. At that time, the width of the slide arm 54 is determined by the width of the notch 21 formed in the table 2 at the painting position 9b.
Since the width of the slide arm 54 is narrower than the width of the table 2, the slide arm 54 can pass through this notch and come into contact with the metal plate 9 from the underside of the table 2. After that, the metal plates 9 and 9 are attached to the suction plates 55 and 56 respectively.
, the slide arm 53 rises to the top of the manipulator body 51, and the slide arm 54 rises to a position where the bottom surface of the slide arm 54 is slightly above the top surface of the table 2, and then stops. .

Next, the manipulator 5 moves in the longitudinal direction of the table 2 away from the metal plate mounting base 3 by rotation of the feed screw 81, with the metal plates 9, 9 being attracted to the suction plates 55, 56, and the groove 8 It stops when the support rod 52 comes into contact with a limit switch 84 provided inside. The state of the manipulator at that time is shown in FIG.

Now, when the manipulator 5 stops in the state shown in FIG. 6, the metal plate 9 sucked by the suction plate 55 is located directly above the coating position 9b.

The slide arm 53 descends immediately after the manipulator 5 stops, brings the metal plate 9 attracted to the suction plate 55 into contact with the coating position 9b on the top surface of the table 2, and stops, and releases the suction of the suction plate 55. Then, the metal plate 9 is placed at the coating position 9b.

After that, the slide arm 53 is moved to the manipulator body 5.
At the same time, the manipulator main body 51 rotates 90'' clockwise relative to the support rod 52 when viewed from the metal plate mounting base 3 side.

The state of the manipulator 5 at that time is shown in FIG. When the manipulator 5 is in the state shown in FIG. 7, the metal plate 9 attracted by the suction plate 56 will face the metal plate holder 10 of the binding machine located at the metal plate loading position 9c.

The metal plate holder 10 is made by bending the metal plate 9 in an arc shape in the longitudinal direction so that the metal plate 9 can be gripped with long holes 91, 91 formed along both short sides of the metal plate 9 being vertically opposed to each other. It has a shape as shown in FIG. As a result, after the metal plate 9 is taken into the binding machine together with the metal plate holder 10, the binding machine moves through the elongated holes 91, 91 of the metal plate 9.
The metal plate 9 can be easily attached to the product by winding the banding band around the product while passing the banding band through it from the bottom to the top as if sewing the metal plate 9 around the product.

Now, from the state shown in FIG. 7, the slide arm 54 moves along the manipulator main body 51 in the direction of the metal plate holder 10, brings the metal plate 9 sucked by the suction plate 56 into contact with the metal plate holder 10, Release the suction of the suction plate 56,
It further moves toward the metal plate holder 10, and loads the metal plate 9 into the metal plate holder 10 while warping the metal plate 9 into an arc shape according to the shape of the metal plate holder 10, as shown in FIG.

Thereafter, the slide arm 54 moves in a direction away from the metal plate holder 10 to the end of the manipulator body 51 and stops. In this state, the manipulator 5 waits until the laser printing device 6 completes the printing operation and the paint injection nozzle 7 completes the coating operation, which will be described later.

As shown in FIG. 7, as the manipulator main body 51 rotates, the slide arm 53 retreats from above the coating position 9b, and then a predetermined amount of transparent paint is sprayed from the paint spray nozzle 7 installed above the coating position 9b. The printed surface of the metal plate 9 placed on the coating position 9b is coated with the transparent paint.

When the printing work and the painting work are completed, the manipulator main body 51 rotates 90° counterclockwise with respect to the support rod 52 when viewed from the metal plate mounting stand 3 side.

As a result of the above, the manipulator 5 has returned to the initial state described in its operation, that is, the state shown in FIG. 8, and again,
By repeating the above operations, the printing plate loading device shown in this embodiment prints on a metal plate with a laser printing device, coats the printed surface with transparent paint, and loads it into the metal plate holder of the binding machine. Continuously perform the above steps.

〔effect〕

As described in detail above, according to the printing board printing loading device according to the present invention, printing of fixed information, which conventionally was outsourced to an outside specialist and took four days to one week, can be performed by registering the printing in advance. Fixed information provided by Commerce and Industry.

Since the beam irradiation position of the energy beam printing device is controlled, time can be significantly reduced.

In addition, the variable information that was previously printed by hand or by stamping by the operator's hand can be printed by controlling the beam irradiation position of the high-energy beam printing device using the variable information read directly from the inspection process, increasing work efficiency. This improves the printing quality and prevents the printed content from disappearing.

Furthermore, since the printed surface is coated with a transparent paint, the printed surface can be kept clear for a long period of time, and the present invention has excellent effects.
