Is being done. Such an engraving apparatus is generally configured such that a plurality of engraving punches are provided on an index table, and the index table is moved by data from the information processing apparatus to set a desired engraving punch at a predetermined position.

In such a device, since the marking devices are sequentially arranged in the direction of movement of the index table, the index table must be reciprocated in order to select a desired marking punch. In particular, when a plurality of stamps are made on a single work, there is a problem that useless movement occurs and the work efficiency is reduced. Of course, in order to solve such a problem, it is conceivable to drive the index table by a servomotor and control the rotation position based on the engraved data. However, there is a problem that the apparatus becomes complicated and cost increases. The present invention has been made in view of such circumstances, and a purpose thereof is to reduce the amount of movement of an index table for accommodating an engraving punch as much as possible without complicating the apparatus. An object of the present invention is to provide a new stamping device capable of stamping at a high speed.

[0003]

According to the present invention, to solve such a problem, data obtained by measuring data of a workpiece is classified into a plurality of classes according to a predetermined standard, and rank data is classified. Measurement data processing means for outputting position data representing the target position of, and an engraving punch corresponding to the rank data is arranged in ascending or descending order of the engraving data, and an engraving mechanism configured to be able to select an engraving position, Conversion means for classifying rank data and position data from the measurement data processing means as a pair and sorting the rank data in ascending or descending order, and selecting the marking punch of the marking mechanism in the order of the data of the conversion means, And a control unit for moving to a position corresponding to the position data.

[0004]

A plurality of rank data to be imprinted are rearranged in ascending or descending order based on the currently operable engraving punch. At this time, the engraving positions are also rearranged correspondingly. The marking punches are selected in the arrangement order of the rearranged rank data, and are moved to the selected marking positions. As a result, the necessary marking can be performed only by moving the marking punch monotonously in the arrangement direction, and the backward movement of the index table becomes unnecessary.

Next, the operation of the apparatus constructed as described above will be described with reference to FIG.
A description will be given based on the flowchart shown in FIG. In this embodiment, the measurement results are expressed as “0, A, B, C, D, E,
The case of classifying into eight ranks of “F, G” and engraving them will be described as an example. 1 at the measuring station
When the first measurement is performed for one workpiece, the data of the odd-numbered flange surface width from the measuring station, that is, the measured data of the width of each flange recognized as position 1 and position 3 is output in correspondence with the position. (Step b), the measurement data processing device 80 determines which of the eight ranks the measurement data belongs to (step b), and determines the flange surface width at position 1 as rank “C” and position 3 (step b). The flange surface width is output as rank "F" together with the measurement position (step c). When the first measurement is completed, the measuring devices 6 and 7 are moved to measure the flange surface width at the position 2 and the position 4 (step a), and the flange surface width at the position 2 is ranked “F”, Also, position 4 is determined to be rank “D” (step b) and output together with the measured position.

When a predetermined number of data are stored for one work in this way (step d), the storage circuit 83 associates the rank data with the measured position.
To be stored. As a result, as shown in FIG.
Assuming that “C” is stored in the first area of No. 3 and that it is the second area, “C” is stored in the first area of the storage circuit 83 and “F” is stored in the third area ( Step e).

The marking mechanism control device 70 receives the data transferred from the measurement data processing device 80, and stores the data in order corresponding to the measurement position (step d). Next, the type of the engraving punch currently present at the position of the hammer 66 is converted into a numerical value starting from 1 when the type is represented by the order from the reference point (for example, the engraving punch 57 of “0”). The same continuation symbol as “0, A, B,
C, D, E, F, G ".
That is, “0, A, B, C, D,
E, F, and G are prepared, and the engraving punch 60 of “C” is currently located on the hammer 66 and the engraving punch 57 of “0” is the reference. Is located at the fourth position from the reference engraving punch 57. Therefore, the ordinal number starting from "0" is converted into a numerical value "3" (step f). Further, this numerical value “3” is converted to the continuous symbol “0,
A, B, C, D, E, F, and G ”are arranged in the order of starting from 0, and are inversely converted to the original value representing the fourth rank“ C ”(step). G).

When the conversion is completed, the work W whose measurement has been completed is conveyed to the marking station by the belt conveyor 47 (step). At this stage, the marking mechanism control device 70 stores the rank data (FIG. 6) stored in the storage circuit 83 in the first arithmetic storage unit 9.
2 and the paired position data are stored in the second operation storage means 93. That is, the first calculation storage means 92
, Rank data “C, A, F, D” in order (FIG. 7)
I), and the second operation storage means 93 stores "1,
2, 3, 4 "are respectively stored (FIG. 7
II).

At the time when these data are obtained, the sorting means 95 pairs the rank data and the position data stored in the first calculation storage means 92 and the second calculation storage means 93 with each other. When the letters representing the ranks of the storage means 92 are viewed as numerical values in the order of arrangement, the types of the engraving punches facing the hammer 66 are rearranged in ascending or descending order from the one closer to the numerical value when the numerical value is described above. .
That is, the rank data “C, A, F, D” is “4,
2, 7, 5 ". On the other hand, if the marking punch 57 faces the hammer 66, the rank data stored in the first calculation storage means 92 is in ascending order based on" 0 ". In the order of "2, 4, 5, 7",
With this order movement, the position data paired with these rank data is also rearranged to “2, 1, 4, 3” (step nu) (FIG. 8).

When the rearrangement of the rank data and the position data is completed, the marking mechanism control device 70
Reads the rank data “A” to be marked first and the position data “2” by accessing the head area of the third calculation storage means 94. As a result, the index cylinder driving means 96 moves the index table 54 by two steps from the current position to move the “A” marking punch 58 to the position of the hammer 66, and the marking position finding cylinder driving means 96 The cylinder 51 is operated to move the marking position to the second digit of the marking area (step). When such preparation is completed (step e), the hammer 66 is operated to engrave an engraving "A" at the second digit position (step w). When the first engraving is completed, the engraving mechanism control device 70 accesses the second area of the third operation storage means 94 to rank data “C” to be engraved secondly and position data “1”. And the same process as described above is repeated. As a result, the index cylinder 65 is moved to the position where the stamping punch 6
0 is selected, and at the same time, the positioning cylinder 51 drives the base 52 to move the marking punch 60 to the first digit (step). When the marking punch 61 is set at a predetermined position (step o) and the hammer operates (step w) in this way, "C" is stamped on the first digit of the marking area of the work.

In the same manner, the index table 54 is moved in one direction while the readout position of the third operation storage means 94 is moved to the third and fourth areas, and stamping punches are sequentially selected. The base 52 is moved so as to be at the desired digit position, and the engraving is performed.

As a result, as shown in FIG. 9, "A" is added to the second digit in the first engraving operation (I in FIG. 9), and "A" is added to the first digit in the second engraving operation. "C" is (II), and "D" is (II) in the fourth digit in the third engraving operation.
I) Finally, "F" is stamped on the third digit (IV). Thus, when selecting the marking punches 57 to 64, it is not necessary to make the index table 52 perform a backward operation, so that a required marking punch can be selected at a high speed. Needless to say, the moving distance by the positioning cylinder 51 can be extremely small, so that the stamping punch can be positioned at a predetermined position in a very short time as compared with the stamping punch selection time even when reciprocating. become.

The currently operable marking punch is "B".
, The rank data “C, A, F,
"D" is rearranged to "C, D, F, A" in ascending order, and to "F, D, C, A" in descending order.

When the engraving operation is automatically performed as described above, the monitor control means 98 reads the raw rank data transferred from the measuring station stored in the data storage means 90 and displays the read raw rank data. Output to the unit 71. As a result, as shown in FIG. 10A, all ranks to be imprinted on the work W are displayed corresponding to the digits of the engraving position.

On the other hand, if the operation of the engraving mechanism 50 is stopped in the course of the third engraving operation due to some inconvenience, the selector switch 72 is switched over, and the data conversion means 99 causes the index cylinder driving means 96 and The engraving position locating cylinder driving means 97 sets “9” in the data “D” currently read out from the third arithmetic storage means 94 by two.
The addition is performed in a hexadecimal system, and the result of the addition is converted into hexadecimal numbers by extracting lower 4 bits of data. These data are shown in FIG.
As shown in (1), the rank data is displayed at the highest digit of the display 71, and the position data "4" is displayed at the lowest digit. That is, in the third data, since the rank data is “D” and the position data is “4” as shown in FIG. 8, if the engraved punch “D” is represented by an ordinal number starting from 0, Since it becomes "4", when "9" is added to this numerical value "4", it becomes "13" in decimal. When this is expressed in a binary number, it becomes "1101", which is a hexadecimal number (0, 1,.
2 ‥‥ 9, A, B, C, ΔF)
By directly outputting this to the display 71, the type “D” of the selected engraving punch can be displayed. When a numerical value out of the rank is output, its binary number is "10000", so if only the last four digits are taken, it becomes "0000", which matches "0" indicating nonstandard. Become. With this display, the digit position where the marking is stopped and the type of the marking punch can be easily confirmed on the display 71.

In this embodiment, the data storage means and the first to third calculation storage means are each constituted by independent storage means, but the single storage means is divided into a plurality of areas. Obviously, the same effect is obtained even if the above operation is performed. In this embodiment, the case where the surface width measurement data of the cam holder is engraved has been described. However, it is apparent that the present invention can be applied to an inspection apparatus or a measurement apparatus which needs to perform a plurality of engravings on one work.
