Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a stamping machine, and is capable of almost automatically carrying in, taking out, and stamping a stamping board, regardless of its shape, dimensions, etc. It can be done.

(Prior Art) As a conventionally commonly used stamping machine, there is one as shown in FIG. 16, for example.

In the figure, 141 is a base, and two support columns 142 and 142 are erected in parallel on the top and end sides of the base, and a cylinder mounting body 143 is fixed through the support columns 142 and 142. Two support rods 144, 144 are extended horizontally and parallel to each other from both ends of the cylinder mounting body 143, and a horizontal movement bridge is installed between the supports 145, 145 that are penetrated by the rods 144, 144. On the plate 146,
By fixing the tip of the air cylinder 147 attached to the cylinder attachment body 143, the movable plate 1
46 is movable in the horizontal direction. Horizontal moving plate 1
A vertically movable plate 149 is provided below 46 via two vertical rods 148 and 148, and the tip of an air cylinder 150 provided at the center above the horizontally movable plate 146 is fixed to the vertically movable plate 149. Accordingly, the vertically movable plate 149 is movable in the vertical direction relative to the horizontally movable plate 146. A marking head 15 is provided on the lower surface side of this vertically movable plate 149.
1 is screwed onto the plate 153 to be stamped, which is placed on the rail 152, 152. The movement of the flat bell 154, 154 causes the vertically movable plate 149 to substantially hang down, and then the movable plate 149 When the marking head 151 comes into contact with the stamping target plate 153, stamping becomes possible. Note that 155 is an ink fountain.

The stamping head 151 is a commercially available one as shown in FIG. It is constructed according to the following.

A large number of printed characters are embossed on the surface of the rubber belt 159, and by rotating this rubber belt 159 together with the large roll 157, it is possible to imprint various character arrangements.

(Problems to be Solved by the Invention) In the above-mentioned conventional technology, a normal commercially available stamping head 1
51 is simply attached to the vertically movable plate 149 as described above, when changing the number, spacing, and direction of characters to be stamped, the stamping head 151 itself must be replaced or its orientation manually changed. I had to change it at work.

Further, for example, as shown in FIG.
If a concave-convex shape is formed on the top by electrical wiring, etc., the size of the marking head 151 itself makes it impossible to stamp in a narrow place where wiring, etc. are densely packed, and the marking position is naturally limited. It was supposed to happen.

Furthermore, if it is desired to stamp the back side of the stamp board 153, the stamp board 153, which has been taken out of the machine after the front side has been stamped, is turned over and placed on the rail 152 again. The procedure had to be done primarily by acquisition.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to reliably stamp even in a narrow place on a stamping board, regardless of the shape, size, etc. of the stamping board. To provide a stamping machine that can easily change the arrangement, number, spacing, and direction of characters to be stamped, and can also stamp both sides of a board to be stamped during a series of loading and unloading operations. It's about doing.

Moreover, they are about the rotation axis as the rotor shaft 37 rotates. It will rotate around.

Reference numeral 61 denotes a stamp rod, which is shaped like a long bar with a square cross section. A rubber stamp 62 in which a specific character is embossed is attached to the lower end surface of the stamp rod 61, and a mounting pin 63 is provided on the upper end side. The mounting pin 63 is machined into a T-shape at one end and has a head 64, and the head 64 is fitted into an elongated hole 65 provided on both sides of the upper end of the stamp rod 61, thereby allowing the stamp to be removed. A cushion spring 66 is attached to the rod 61, and a cushion spring 66 is interposed between the attachment pins 63 and the stamp rod 61. Reference numeral 67 denotes a slide lever, which is available in two types, long and short, and has a slide hole 68 at one end, a mounting hole 69 at the center, and a mounting recess 70 at the other end. The slide lever 67 is fixed to the stamp rod 61 by fitting the mounting pin 63 into the mounting hole 69 and tightening the bolt. Further, 71 is a bushing lever, which is composed of a contact portion 72 and a mounting plate portion 73 that stands perpendicularly from the upper surface of the contact portion 72. On one end side of the contact portion 72,
A rod recess 74 having a cross-sectional width substantially equal to the cross-sectional width of the stamp rod 61 is formed, and a notch 75 into which the mounting recess 70 of the slide lever 67 fits is formed at the upper end of the mounting plate 73. That is, the bush lever 71 is fixed to the slide lever 67 by the engagement between the notch 75 and the mounting recess 70, but the rod recess 74 merely accommodates the stamp rod 61. It can move relative to the stamp rod 61 by the amount of expansion and contraction of the cushion spring 66 mentioned above. In this way, the stamp rod 61 to which both levers 67 and 71 are attached is moved in the vertical direction relative to the slide shaft 58 (that is, in the rotor shaft 37
(a direction parallel to the rotation axis L0).

At this time, since the slide shafts 58 are arranged alternately on the large-diameter opening 50 and the small-diameter opening 51 in plan view as described above, the longer one is arranged as shown in FIG. The slide lever 67L is attached to the slide shaft 58 on the small diameter 51, and the shorter slide lever 67L is attached to the slide shaft 58 on the small diameter

Thereafter, after the carrying-in device 4 is brought down, the reversing machine 6 is rotated in the horizontal direction, and the printing plate 3 is reversed to the carrying-out device 5 side.
Next, the unloading device 5 is raised, and the printing plate 3 is supported by both the reversing machine 6 and the unloading device 5.

At this position (that is, the diagonally shaded position W in FIG. 1), stamping is performed on the stamping plate 3.

That is, first, while the above-described stamp plate 3 is being carried in, a predetermined rubber stamp 62 selected by the rotation of the rotor shaft 37 is applied through the vertical movement of the ink fountain 90.
(eg, letters A, B, C) are inked. Then, the X-axis arm 7 and Y-axis arm 8 are operated to move the stamping head 17 to a predetermined stamping location, and the pusher rod 95 advances downward from a specific pusher cylinder 94 among the four. At this time, rotor shaft 3

The carrying out bag W5 is lowered, and the support arm 133 of the reversing machine 6 is inverted 180 degrees around the center boss 130, so that the printing plate 3 is turned over, and the carrying out device 5 is raised again, and this time the back side is stamped. be exposed. When the stamping on the back surface is completed, the stamping board 3 is carried out in the X-axis direction along the rails 101 of the carrying-out device 5, and proceeds to the next step. The above-mentioned operation is just an example, and it is of course possible to set the program to print only on the back side or only on the front side.

According to this embodiment described in detail above, regardless of the size of the stamp head 17 itself, the stamp rods 61 can be pushed down one by one to stamp one character at a time. It is possible to reliably imprint even in a small space regardless of the uneven shape caused by wiring, etc., and the character spacing, number of digits, and arrangement can be freely selected. Further, the direction of the characters can be set arbitrarily depending on how the pusher cylinders 94 are arranged, and in this embodiment, four cylinders 94 are provided at 90 degree intervals, so for example, the character arrangement a shown in FIG.

The direction of the stamped characters can be selected from four directions b, c, and d, that is, directions corresponding to the four sides of the stamping board 3.

Furthermore, even if the stamping plate 3 changes in various ways, it can be handled only by program control, such as the arrangement of the characters and the operation of the loading and unloading devices 4 and 5, without directly modifying the device itself. This makes it possible to fully automate the stamping process and greatly expand versatility. Further, since the reversing machine 6 is provided between the carrying-in and carrying-out devices 4 and 5, it is possible to stamp the front and back sides of the printing plate 3, as described above.

Note that the embodiments according to the present invention are not limited to those described above.

For example, the fixed position holding means 83 may be configured to reliably return the stamp rod 61 to its original position.
The method is not limited to the above-mentioned spring, but a rubber string or the like can also be used instead. Furthermore, in the arrangement of the slide shafts 58, if the size of the marking head 17 itself is not significantly affected by reducing the number thereof, it is not necessary to arrange them alternately as described above.

Further, the reversing machine 6 may be configured such that the vertical axis motor 117 is installed in the horizontal direction, that is, in the Y-axis direction, and the support arm 133 is rotated in the vertical direction. In this case, when the stamping machine 3 is transferred from the carrying-in device 4 to the carrying-out device 5 by the reversing machine 6, it is turned upside down.

Furthermore, in the present invention, the term "sealing" is used in a broad concept that includes, for example, stamping when there is no need to apply ink. The tip of the rubber stamp 62 may be replaced by a hard print. Furthermore, it goes without saying that the driving method for each of the arms 7.8 is not limited to the above-mentioned pole screw method.

(Effects of the Invention) According to claim (1) of the present invention, the marking head 17 can be quickly set to a desired location by operating the X-axis and Y-axis arms 7.8, respectively.

According to claim (2) of the present invention, the stamp rods 61 can be protruded one by one from the marking head 17 and stamping can be performed, so even if there is a narrow place on the stamping board 3 where wiring etc. are crowded, You can make sure to place your stamp in that spot. In addition, since the marking head 17 is movable in both directions via the X-axis arm 7 and Y-axis arm 8, the arrangement, number, and spacing of characters to be stamped can be freely changed, and the stamping process can be improved. Automation will be achieved.

According to claim (3) of the present invention, by providing the reversing machine 6 equipped with the reversing mechanism 124, the back surface of the stamping board 3 is This means that the stamping process can be substantially fully automated, and the versatility of the stamping process is significantly increased, such as by stamping only on the back side.

Furthermore, according to claim (4) of the present invention, the pusher 96 is configured to move along the X-axis and the Y-axis with the rotation axis L0 as the origin in plan view.
Since two pushers are provided on each axis, one of the directions along the four sides of the stamping plate 3 can be selected, and one of the pushers 96 properly arranged in advance can be selected. As a result, the direction of the characters to be stamped can be easily optimized.
