Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable automatic stamping device used to stamp symbols and numbers indicating predetermined standards, certification, dimensions, materials, etc. on steel plates before shipping them.

Conventionally, this type of work has been carried out using a method as shown in FIG.

That is, one method is to use iron type A as shown in FIG. 1A.
3 in series and set it on the set metal fitting A2, place it on the required steel plate 80, and use a hammer A1 weighing about 2 kg.
The head of the set fitting A2 was struck at the same time, and one set of markings was made with one blow.

Another conventional method is to obtain the required iron type B as shown in Figure 1B.
3 are arranged in series and set on the set metal fitting B2, placed at a predetermined location on the steel plate 80, and stamped by hitting the head of each iron type B3 one after another with a light weight hammer B1. Met.

Therefore, the conventional method is completely manual and has the disadvantage of being extremely inefficient.

Furthermore, the symbols, numbers, etc. to be stamped often range from 7 to 40 digits, and the human stamping ability using a hammer is limited to about 7 characters per set.
Six pieces have to be prepared and stamped in a predetermined manner, and this also has the drawback that the work requires a considerable amount of time.

In addition, when stamping with a hammer, it is difficult to obtain a clear stamp unless you hit directly above the iron type, and it is difficult to accurately determine the striking point and apply uniform stamping force to each set of characters. The disadvantages of this method were that it required considerable skill, and the work was hard and dangerous.

Therefore, the present inventors intended to improve the conventional stamping work which has many such drawbacks, and developed the portable automatic stamping device of the present invention.

As is well known, a steel sheet production line already has stamping equipment using a large device, but this marking equipment is immovable and is incorporated into a part of the line as a factory facility, and is an extremely expensive large-scale equipment.

In the current production of steel plates, many steel plates are piled and stocked without going through this marking equipment, and each of the stacked steel plates is stamped with a predetermined marking code before shipping.

The steel plate to be worked on is 2 x 9 m - 0.9 x 1
．． It is a thick board with an area of about 5 m.

Therefore, one object of the present invention is to provide a stamping device that can be easily carried by anyone, can be easily set at a predetermined position on a steel plate, and is easy to operate.

Furthermore, one of the other objects of the present invention is to replace the hammer with a pressure-controlled cylinder and to provide a continuous stamping mechanism that enables the cylinder to efficiently perform a series of consecutive markings by simply operating a switch. The present invention aims to provide an automatic stamping device having the following features.

Furthermore, one of the other objects of the present invention is to make it possible to freely replace a type cassette body arranged in a large number of digits, and to clearly display a series of display codes by automatically moving the pitch of one embossing pin. An object of the present invention is to provide an automatic engraving device equipped with a continuous engraving position setting mechanism that enables engraving on the surface of the object.

Furthermore, another object of the present invention is to provide a pitch feeding operation mechanism in which the above-mentioned continuous marking position setting mechanism operates in accordance with the movement of the hammer body that continuously strikes the marking pin. The present invention aims to provide an automatic stamping device having the following features.

Furthermore, it is an object of the present invention to provide an engraving device having a brake mechanism that prevents the device from changing its set position once set during the engraving operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a portable automatic stamping device of the present invention will be specifically described below with reference to the drawings.

FIG. 2 is a perspective view showing the entire apparatus according to an embodiment of the present invention, in which 1 is a hammer body that performs a striking action by an engraving cylinder 2, and 6 and 7 are vertically movable hammer bodies whose lower ends are connected to the hammer body 1. The sliding rods 6 and 7 are used to operate the continuous stamping mechanism A and the pitch feeding operation mechanism B.

Furthermore, in the figure, air transmission circuits to each air braking device such as a cylinder are omitted.

30 is a clamping plate for clamping a required steel plate in the thickness direction, and this plate 30 is connected to a clamping cylinder 32.
It is raised and lowered by

A pair of sliding irons 36 and 37 for clamping plates are provided in parallel to the operating shaft 328 of the clamping cylinder 32.

42 is a brake cylinder provided behind the cylinder 32.

Each of the cylinders 2, 32, and 42 described above is attached to an appropriate position on the top of the box base 1.

Reference numeral 5 denotes a handle that is convenient for carrying the device and setting it on a steel plate.

A continuous marking position setting mechanism D is provided below the hammer body 1.

First, as shown in FIGS. 2 and 3 above, the continuous embossing mechanism A
will be explained in detail.

FIG. 3 is a left side view of the entire device, and the continuous stamping mechanism A operates the switch 10 by the operation of the sliding rod 6 for vertically moving the hammer body, which moves up and down following the stamping cylinder 2.
The user intends to operate the lever 10L.

The on/off operation of this switch 10 is controlled by the stamping cylinder 2.
The compressed air person is the one who controls the exhaust.

With the switch lever 10L placed in the middle, a pair of upper and lower lever operating fittings 12 and 14 are attached to the distal end portion 8 of the sliding rod 6 at appropriate intervals.

The contact fittings 13 and 15 that come into contact with the lever 10L are provided with buffer springs 13a and 15a.

The lever operating fittings 12 and 14 are screwed to the rod 8 so that the distance between them, that is, the on/off time interval of the switch 10 can be adjusted.

11 is a switch box housing a cylinder control circuit, 11A is a push button switch for energizing the clamping cylinder 32 and the pitch feed cylinder 52, and 11B is a push button switch for energizing the brake cylinder 42 and the stamping cylinder 2. This is a push button switch.

Now, when switch 11B is turned on, switch 10 is turned on at the same time.
Since the lever 10L is turned on when facing upward, the stamping cylinder 2 has become popular, moves downward, directs the hammer body 1 toward the stamping operation, and when stamping is completed, the lever contact fitting 13 turns the lever 10L downward. to defeat.

When the lever 10L is facing downward, the switch 10 is turned off, the cylinder 2 is exhausted, and the cylinder 2 is reversed to the upward movement, the rod 6 is raised accordingly, and the lever contact fitting 15 is connected to the lever 10.
By tilting L upward again, the cylinder descends again, making it possible to perform a continuous stamping operation.

Of course, this continuous stamping operation is stopped by turning off the switch 11B.

It can also be stopped by turning off a switch 64 in a continuous marking position setting mechanism D, which will be described later.

Next, the continuous engraving position setting mechanism D will be described with reference to FIG. 2 and FIG. 4, which shows an enlarged front view of a partially cut out main part.

This mechanism D follows the punching motion of the hammer body 1 and moves the punching pin 3 continuously one pitch at a time to strike the iron type 70, and follows the vertical motion of the hammer body 1. A pitch feed operation mechanism B operated by the operation of the other sliding rod 7 performs a pitch feed operation.

The pitch feed operation mechanism B is provided with a protruding pin 22 on the tip shaft 9 of the sliding rod 7, and engages with this pin 22 to turn the slide rod 7 face down (21
“) or raised (21') pin 21. This pin 2
1, a support arm 24 that supports the pin 21 so that it can rise and fall freely, and a spring 29 that always returns the pin 21 to a horizontal neutral position.

The continuous marking position setting mechanism D includes a pin feeding frame 50 that is always suspended horizontally by suspension bodies 56 and 57 with suspension springs 58 and 59 interposed therebetween, and a pin feeding frame 50 that is slidable on this frame 50 (
The embossing pin 3 is held by the embossing pin (to the extent that it slides down due to its own weight),
A pitch feed cylinder 52 for horizontally reciprocating the frame 50, upper teeth 53 and lower teeth 54 formed at an appropriate pitch to set the feed amount of the frame 50 in one pitch degree.
(formed at the right end of the frame 50), an upper claw 51a and a lower claw 51 that alternately engage with the upper and lower teeth 53,54.
b1 A feed pitch number setting mechanism E for setting an arbitrary feed pitch number of the frame 50 is used.

Now, in FIG. 4, when the hammer body 1 descends to stamp the first code and strikes the stamping pin 3, the operating rod 20 is in the raised state.

Therefore, since the feeding frame 50 is in a horizontal state and the upper teeth 53 and the upper claws 51a are engaged, even if the pitch feeding cylinder 52 presses the frame 50 in the direction of arrow a-1, this The frame is stationary, and the embossing pin 3 receives the impact from the hammer body 1 at the position shown in the figure.

After marking the first code, the operating rod 20 begins to descend as the hammer body 1 ascends.

When the hammer body 1 reaches the highest position, the operating rod 2
The lower end 26 of the frame 50 pushes down the hanging body 56 of the frame 50, and the frame 50 moves downward, causing the upper teeth 53 and the claws 51 to move downward.
a is disengaged, and by the pressure of the cylinder 52, the lower tooth 54 and the lower claw 51a are then brought into engagement, and at the same time, the hammer body 1
Due to the action of the continuous marking mechanism A described above, the operation rod 20 moves downward in order to print the next code, the operating rod 20 changes to a rising movement, and the frame 50 then returns to its original horizontal state. There is.

This is accomplished by the action of spring 56a as lower end 26 of rod 20 moves away from suspension body 56.

The frame 50 returning to the horizontal state engages with the tooth 53b of the upper teeth 53 following the first engaged tooth 53a.

Then, the second stamp is applied to the stamp pin 3 which has been moved onto the next iron type.

In this way, when the embossing pin 3 moves intermittently at a unit pitch and embodies a predetermined number of digits, the switch operating rod 61, which is attached to the frame 50 and horizontally interlocked with the frame 50, switches the switch. When the movable contact lever 64a of 64 is pushed, the stamping cylinder 2 stops operating.

Of course, the continuous embossing mechanism A is also stopped.

62 is a pitch scale plate displaying the required number of digits, and is attached to the side surface of the box base 4.

61a is an indicator fixed to the switch operating rod 61.

By aligning the pointer 61a with a desired scale position on the scale plate 62, the marking pin can be advanced intermittently by the desired number of digits, that is, the number of pitches, to perform marking.

The tip of the operating shaft 52S of the pitch feed cylinder 52 is connected to the frame 50 via a roller 52r.

55 is a vertical guide body for the roller 52r provided on the frame 50.

Therefore, the cylinder 52 can transmit the suppressing action to the frame 50 even while the frame 50 is moving up and down.

In addition, since the hanging bodies 56 and 57 hold the frame 50 via a pair of upper and lower rollers 56r and 57r, respectively, the frame 50 can be moved to the left or right, regardless of its upward or downward movement.
Can move to the right.

After completing the predetermined stamping, the frame 50 moves in the direction of arrow a-7 as the cylinder 52 returns, making it possible to perform stamping work on a new steel plate.

This return movement of the frame 50 in the direction of arrow a-7 is performed with the frame 50 in a horizontal state, and the upper claw 51a is in a shape that does not interfere with the upper teeth 53.

That is, since the upper claw 51a is rotatably attached to the claw holder 51 and has a spring 51c interposed at the end of the claw, the upper claw 51a is rotated using the pin 51p as a fulcrum along the tooth surface of the upper tooth 53 that is returning. It rotates.

The pitch of the upper teeth 53 matches the spacing between the iron type characters 70.

The lower tooth 54 and the lower claw 5lb are formed to have a tooth width that is 1/2 pitch of the upper tooth.

In principle, it is effective if the tooth width of the lower teeth 5lb is narrower than the upper tooth pitch.

A type cassette body 75 in which a large number of iron type characters 70 are set.
can be detachably attached to the bottom plate of the box base 4.

Reference numeral 71 indicates a protruding type part, and the figure shows the height of the type part protruding from the bottom surface of the box base 4, which means that when the steel plate 80 is completely sandwiched, the type part 70 will be It retracts upward by the above-mentioned amount of protrusion and becomes flush with the bottom surface of the cassette body 75 or the bottom surface of the box base body 4.

That is, each type body 70 is inserted into the cassette fitting from above, and is prevented from falling downward as shown in the figure.

This configuration can be implemented, for example, by forming the iron type body 70 into a stepped shape and arranging a stopper liner in the cassette body 75 that comes into contact with the stepped shape.

FIG. 3, FIG. 5 showing an enlarged cross-sectional view taken along the line XX in FIG. 3, and FIG. The brake mechanism C will be explained with reference to FIG.

This brake mechanism C is installed in the rear part 4B of the box base 4, and presses brake plates 41a, 4lb, 41c, and 41d against sliding rods 36 and 37 for clamping plates by operating a brake cylinder 42. It is an attempt to carry out an action.

428 is the operating shaft of the brake cylinder 42, 44 is the brake operating arm, and each brake plate 4 1 a, 4 l b
, 41c, 41d are connected to the brake operating arm via connecting pins 45p, 41p and link arm 45,
When the operating arm 44 tilts down each of the brake plates 41a to 41d using the pin 41p as a fulcrum in accordance with the downward movement of the operating shaft 42S, the clamping plate 30 becomes immovable with respect to the box base 4.

In accordance with the lifting operation of the brake cylinder 42, each of the brake plates 41a to 4lb releases the pressing action against the rods 36 and 37.

5 indicates a pair of left and right handles. Figure 7 is the third
These are position setting tools with clamps provided at the bottom left and right sides of the box base 4 in Figures 5 to 5.

This position setting tool is a guide rail body 4 with grooves 4S protruding from the guide rail body 4.
L is fixed horizontally to the bottom of the left and right side plates of the box base 4, and by tightening the screw body 4b, a pair of left and right sliding positioning pieces 4a that can be fixed at any position on the rail body 4L are used. It is configured.

Therefore, the desired steel plate 8 is attached to the pair of sliding positioning pieces 4a.
By pressing the device so that the end faces of the two are in contact with each other, the desired clamping position can be set.

It is also effective to mark required scale lines etc. on the rail body 4L.

Here, one step of the stamping operation of the stamping device of the present invention having the above-mentioned configuration will be explained.

The device is connected to a required compressed air source, and the feed pitch number setting mechanism E is set to match the predetermined number of display code digits.

→ Insert the clamping plate 30 onto the lower surface of the stocked steel plate 80, and approximately align the device at the predetermined marking position.

In other words, the box base 4 is placed on the upper surface of the steel plate 80 to set the position of the apparatus.

→Turn on switch 11A (Fig. 3).

→The clamping cylinder 32 is energized, and the clamping plate 30 rises to clamp the steel plate 80.

Before completing this clamping operation, the device must be accurately set in the predetermined position once again.

At the same time, the pitch feed cylinder 52 is also energized by turning on the switch 11A.

→Turn on switch 11B (Fig. 3).

→The brake cylinder 42 is energized, and the brake mechanism C
acts, and the clamping state of the clamping plate 30 is firmly maintained.

At the same time, the switch 11B is turned on to energize the stamping cylinder 2, which descends and strikes the stamping pin 3 to stamp the first code.

Following the lowering, stamping, and raising operations of the cylinder 2, the continuous stamping mechanism A, the pitch feed operation mechanism B1, and the continuous stamping position setting mechanism D that feeds the stamping pin 3 intermittently in pitch degrees operate in conjunction with each other. Complete the stamping.

Upon completion of this, the switch 64 is turned off by the feed pitch number setting mechanism E, and the stamping cylinder stops the stamping operation.

→Turn off switch IIB.

→The brake cylinder 42 reverses upward and the brake mechanism C is released.

→Turn off switch 11A.

→The clamping cylinder 32 operates to release the clamping state, and at the same time the pitch feed cylinder 52 also returns to its original position and stops. →Remove the stamping device from the steel plate 80.

The device of the present invention that can perform the stamping action as described above has the following features:
According to the results of implementation by the present inventors, for example, a 7-digit display code can be executed in about 3 seconds.

Therefore, the time required for conventional stamping work of this type is 1/10th.
The work can be reduced to ~1/20, and moreover, the work can be transformed from a dangerous and hard labor to a safe and extremely easy light work, and the work efficiency in this type of work can be improved. The benefits of labor-saving improvements are extremely significant.

Furthermore, the device of the present invention is easy to handle and transport;
