Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simple automatic marking method using fluid pressure via a roll.

Traditionally, when shipping metal plates, shapes, pipes, etc., a combination of symbols, figures, numbers, etc. were engraved to indicate the brand, standard, material, dimensions, reference number, date of manufacture, manufacturer's name, etc. It is customary to apply

In this case, for example, a mass production line such as a steel plate production line may be equipped with marking equipment using large equipment, but general metal materials are stocked without marking, and stamped before shipping. The present invention is a marking method intended for such cases, and the methods shown in FIG. 1A and B are conventionally mainly used.

The method shown in FIG. 1A is to set a plurality of stamps As made of A iron 10, for example, in series, and set them on the set fitting A2, place them on the surface of the material to be stamped 1, and use about 2 mm of aluminum stamping. In this method, the head of the set fitting A2 is struck with a hammer, and one set of stamps is stamped with one blow. 15 Next, the method shown in Figure 1B is to make the required iron stamp B.

In this method, several pieces are lined up in series and set on the set bracket B2, placed on the surface of the material to be stamped 1, and the head of each stamp B3 is sequentially hammered with a lightweight hammer B. Aro. 20 In other words, the conventional method has the disadvantage that the υ and the deviations are manual labor and are extremely inefficient.

In addition, the number of stamps to be stamped is often several tens of digits long, and in the method A mentioned above, the human stamping capacity of the printer is limited to about seven stamps per set. A
2 had to be prepared in order to perform the predetermined engraving, which also had the disadvantage of requiring a long time to complete the work. Furthermore, when stamping with a hammer, a clear stamp cannot be obtained unless the hammer is struck directly above the iron stamp. The work of applying stamping force requires great skill, is hard work, and is highly dangerous.The present invention provides a method of solving this problem with an extremely simple structure. .

'5 The present invention operates fluid pressure in a direction perpendicular to the surface of the material to be marked through a roll, and in a state in which the starting end of the marking array is pressed onto the surface of the material to be marked, a cylinder parallel to the surface of the material to be marked is applied. This is a simple automatic marking method characterized by operating fluid pressure in the direction to roll the roll according to the marking arrangement and sequentially marking the surface of the material to be marked until the end of the marking arrangement.

The present invention will be further explained based on Examples.

Figure 2A is a side view illustrating an example of implementing the present invention, Figure 2B is a partially enlarged view of Figure 2A, and Figure 2C is Figure 2Af)A.
-N sectional view.

In the figure, A is the printing, 1 is the material to be marked, and 2 is the marking arrangement, which is placed on the upper sandwich plate 4 of the material 1 to be stamped, and the upper sandwich plate 4 is the support. It is suspended from a pin 14 fixed to the arm 12 via a hand-shaped frame 15, and is raised and lowered while being guided by guide rods 19 at both ends in synchronization with the raising and lowering of the support arm 12.

The roll 3 is pivotally mounted on the lower part of the support arm 12 by a pivot 13, and the support arm 12 is fixed to the tip of the piston rod 11 of the hydraulic cylinder 8, and as the piston rod 11 expands and contracts, the roll 3 is attached to the guide rod 20, 2σ. You will be guided up and down. The fluid pressure cylinder 8 has a frame body 9 that rolls horizontally by two upper and lower trochanters 10 using the upper beam 17 of the body 16 as a rail, the bottom plate being the clamping bottom plate 5 that clamps the stamped material 1 from below.
It is mounted vertically on a fixed rack and re-routed. The frame body 9 includes another hydraulic cylinder 6 installed horizontally at the end of the upper beam 17.
The tip of the piston rod 7 is pivotally mounted by a pivot bolt 18. Next, the operation of this example will be explained.

First, the stamps are selected and arranged on the upper sandwiching plate 4 to form the stamp array 2.

Next, the simple automatic marking device of this example is carried to the position of the material to be marked, and the attitude of the marking device is adjusted so that the material to be marked is in the state shown in FIG. 2A.

Next, the fluid pressure cylinder 8 is operated to move the piston rod 1.
1 is extended, and the roll 3 is lowered to press the starting end of the marking array onto the surface of the material 1 to be marked.

Next, while maintaining the operating state of the hydraulic cylinder 8, the hydraulic cylinder 6 is operated, the piston rod 7 is extended, and the frame 9 is rolled along the upper beam 17 toward the left in the figure. For example, the roll 3 rolls from the starting end on the marking array 2 while pressing the marking array 2 onto the material 1 to be marked, moves to the end, and rolls onto the surface of the material 1 to be marked noiselessly and automatically. Uniform markings can be applied to each part without requiring any human power.
