Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable automatic marking device that performs marking without approaching the material to be marked.

Conventionally, when shipping metal plates, shapes, pipe materials, etc., symbols, figures, letters, numbers, etc. were combined to display the brand, standard, material, dimensions, inspection number, date of manufacture, name of the 10 manufacturers, etc. It is customary to make a stamp.

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 15 markings and are stamped before shipping. The present invention is a marking device intended for such cases.

In this case, the conventional method mainly used is the method shown in Fig. 1 A and B.
2, place it on the surface of the material to be engraved 1, and hammer the head of the set fitting A2 with about 2 sledgehammers Al to stamp one set with one blow.

25 The method shown in Fig. 1B involves arranging a plurality of required iron stamps B3 in series and setting them on the set metal fitting B2, placing them on the surface of the material to be stamped 1, and using a lightweight marker Bl to remove each stamp B.
This is a method of stamping by sequentially hammering the heads of 3.

Since 10 yuan, the number of stamps to be engraved is often several tens of digits (
However, in method A, the manual stamping ability using a hammer is limited to about 7 pieces per set, so a plurality of set fittings A2 are prepared to perform the prescribed stamping.

ゞ5 Furthermore, when stamping with a hammer, a clear stamp cannot be obtained unless the hammer is struck directly above the iron stamp. Since it is necessary to use stamping force, the work requires great skill, is inefficient, and is hard and dangerous work.

The present invention provides a device that solves this problem.

The present invention provides a stamping array in which letters, numbers, symbols, figures, etc. are arranged in combination, and a press roll that rolls while sequentially pressing the stamping array onto a material to be stamped from the start end to the end of the stamping array. and a pressing mechanism of the press roll to the eight marking array including a fluid pressure cylinder arranged in a direction perpendicular to the surface of the material to be marked, and a fluid pressure cylinder arranged in a direction parallel to the surface of the material to be marked. a machine body equipped with a rolling mechanism for the press roll from a starting end to a terminal end of the stamping array, a bottom plate and a top plate that sandwich the stamped material, and on which a main part of the stamping device is mounted; A mechanism for vertically positioning the machine body with respect to the material to be marked, including a strut for suspension and a hydraulic cylinder; The present invention is a portable automatic marking device characterized by comprising a mechanism for positioning the machine body in the horizontal direction.

Hereinafter, each mechanism will be explained in detail according to the order of operation at each temperature. Mechanism for vertical positioning of the fuselage body FIG. 3 is a side view of the mechanism for positioning the fuselage body 18 at a required height.

These mechanisms include a hydraulic cylinder 3 that is connected to a pedestal via a metal fitting with a pivot pin 50, and has a freewheel 10 pivoted to the tip of a piston rod 16, a stop pin 13 that secures one end of a wire 11, and a stop pin 13 that secures one end of a wire 11. A strut 17 that supports the free wheels 1 and 2 through which the fuselage support frame 14 is suspended; a strut 17 that uses the strut 17 as a rail and slides vertically via a trochanter 51; and a stop pin at the upper end of the strut. 13 and the stop pin 15 of the fuselage receiving frame 14 and the free 10
, 12 and a wire 11 wound and solidified. That is, the fuselage receiving frame 14 has one end connected to the support 1.
The free wires 10 and 12 are wound around the wire 11 fixed to the stop pin 13 at the upper end of the cylinder 7 and suspended by a pulley structure.The piston rod 16 of the cylinder 3 expands and contracts by operating the hydraulic switching valve. When the tip moves up and down, it will move up and down twice as much as its operating stroke.

Therefore, positioning of the body 18 in the vertical direction, that is, in height, can be performed freely and quickly simply by operating the hydraulic valve.
Mechanism for horizontal positioning of the body 18 FIG. 4 is a front view of a mechanism for laterally moving and positioning the body 18.

This mechanism is supported by the fuselage support frame 14, and includes a pneumatic cylinder 4 whose tip end of a piston rod 21 is pivotally fixed to the front of the slide bar 19, and a trochanter pivotally mounted at two locations above and below the fuselage support frame 14. It is composed of a slide bar 19 that is guided and moves laterally, and links 52 that suspend the fuselage 18 at two places in the front of the slide bar 19. When an air valve (not shown) is opened, the piston rod 21 is extended. When moving forward, the slide bar 19 moves laterally guided by the trochanters 20 at two locations above and below, and the machine body 18 suspended by the links 52 at two locations in the front of the slide bar 19 is attached to the steel plate 1 to be stamped. It is positioned by moving horizontally to the top of the upper engraved area.

Originally, the device of the present invention was designed to be lightweight and simple, so it is desirable that it be easy to transport to the stamping location and to position the device to accurately match the desired location on the material to be stamped.・Therefore, in this example, the total height of the material to be stamped is also 1,500r.
v1 and manufactured to dimensions that match this. Marking mechanism FIGS. 5A, B, C, D, E, and F are operation procedure diagrams of the marking mechanism.

This mechanism consists of a stamp array 8, a lower two-digit numerical stamp 9 which is an extension of the stamp array 8, and has an automatic character selection mechanism (not shown), and a pin fixedly planted on a support arm 54 to carry these. A clamping upper plate 29 is suspended from the handle 26 via a hand-shaped frame 27 and moves up and down guided by guide rods 25 and 25 to clamp the stamped material 1 from above.
The body 18 is assembled into a rectangular shape with the clamping bottom plate 28 that clamps the stamped material 1 from below as the bottom plate and the slide guide 56 of the cylinder fixing frame 31 as the top beam, and the body 18 is fixed upright on the cylinder fixing frame 31. A supporting arm 54 that is attached to the tip of the piston rod 24 of the hydraulic cylinder 5 and moves up and down guided by the guide rods 23, 23, and a pin 26 that is fixed to the base of the supporting arm. and a press roll 7 which is pivoted at the tip end with a pivot 57 and presses the markings 8 and 9 onto the material 1 to be marked, a hydraulic cylinder 6 which is horizontally attached to the end of the slide guide 56, and a pivot 53.
The piston rod 22 of the hydraulic cylinder 6 is pivotally attached to the cylinder fixing frame 31 and extends forward to move the cylinder fixing frame 31 laterally on the slide guide 56 via two upper and lower rollers 55, and The arm 58 prevents the robot from falling.

FIG. 5A shows a state in which the aircraft 18 is adjusted in altitude and is on standby at a temperature similar to FIG. 4.

FIG. 5B shows a state in which the machine body 18 is moved laterally by operating the pneumatic cylinder 4 as shown by the chain line in FIG.

FIG. 5C shows the steel plate 1 to be stamped being clamped from below by the clamping bottom plate 28 by operating the hydraulic cylinder 5 arranged perpendicularly to the steel plate 1 to extend the piston rod 24. A state is shown in which the upper clamping plate is lowered from above and clamped, and the starting end of the marking array 8 is pressed with a predetermined pressure using the pressure roll 7.

At this time, the body 18 is guided by the guide rods 30, 30/ and floats slightly in the direction of arrows 59, 5g. Also, aircraft 1
8, the fuselage 18 is configured to be rotatable in the directions of arrows 60 and 101 using D and E as fulcrums.
FIG. 5D shows a state in which the press roll 7 is pressed with a predetermined pressure by the operation of the hydraulic cylinder 5 arranged perpendicularly to the surface of the steel plate 1 to be stamped, and the pressure roll 7 is arranged parallel to the surface of the steel plate 1. Due to the operation of the hydraulic cylinder 6, the cylinder fixing frame 31 of the hydraulic cylinder 5 is guided by the slide guide 56 and moves laterally, so the press roll 7 stamps numbers from the starting end of the marking array 8 through the ending end with a predetermined pressure. This shows a state in which all of the parts 9 are pressed to achieve uniform marking at a predetermined depth.

Fig. 5E shows that the stamping work has been completed, the vertical hydraulic cylinder 5 is activated, the piston rod 24 is contracted, the clamping upper plate 29 is raised with the stamping arrays 8 and 9 placed thereon, and the machine body 18 is moved onto the material to be stamped. The state is shown separated from the steel plate 1.

That is, as the guide rod 30 slightly descends in the direction of the arrow 61, the machine body 18 also naturally descends slightly, and the clamping bottom plate 28 separates from the back surface of the stamped material 1, and the machine body 18 and the stamped material 1 are out of contact, leading to the next step. The machine body 18, which has been separated and opened without contact with the steel plate 1, is moved laterally by the operation of the pneumatic cylinder 4, and is maintained in such a state that there is no hindrance.
The pressure roll 7 is also pulled up by the operation of the hydraulic cylinder 5, the clamping upper plate 29 is suspended from the pin 26, and the cylinder fixing frame 31 is moved sideways by the operation of the hydraulic cylinder 6 to return to the normal position. let That is, by using the apparatus of the present invention, it is possible to uniformly mark each part at a desired depth simply by operating the hydraulic and pneumatic valves and without any physical labor.
