Description

Iron detector test device

The present invention relates to a conveyor system, and more particularly, to an iron detector test apparatus capable of testing an iron detector for detecting iron pieces present on a conveying belt.

In general, a conveyor system is mainly used for transferring products or raw materials to a specific position by moving a belt by a driving roller. When the product is transported, the iron pieces may be conveyed together for some reason on the belt, and when the iron pieces are conveyed together to the working position, the work process is disturbed. In order to prevent the transfer of the iron piece, the conveyor system is installed in the iron sheet detector, which will be described with reference to Figures 1 and 2 as follows.

FIG. 1 is a schematic view showing a conveyor system in which a piece of iron detector is installed, showing a driving roller 11, a plurality of rollers 12, and a belt 13 wound around each roller 11 and 12. On one side of the conveyor system, a piece of iron detector 14 for detecting the pieces of iron present on the belt 13 is installed, and the piece of iron detector 14 emits a warning sound when the pieces of steel pass through the lower part of the conveyor 13. It is necessary to stop the operation of the conveyor system by recognizing that the iron piece is present on the belt 13 (the operation principle of such a iron detector is general and thus the description thereof is omitted).

The iron detector 14 used for this purpose does not detect the iron piece even though the iron piece passes if the detection sensitivity is not appropriate, and does not generate a warning sound. It can also cause a stop.

In order to solve this problem, the performance of the iron detector should be tested from time to time, but the test procedure is as follows. FIG. 2 is a partial perspective view of the portion A of FIG. 1 showing the test method of the iron piece detector 14, in which the test piece 15 is transported by a belt 13 which is transported by an operator throwing the test piece 15 (iron piece) onto the belt 13; In the course of passing through the lower portion of the iron detector 14, the iron detector 14 is tested whether the specimen 15 is normally detected. However, such a test process of the iron detector 14 has the following problems.

(A) Since the operator must go up to the belt 13 directly to recover the specimen 15 after the test of the iron detector 14, there is a risk of a safety accident in which the worker slips on the belt 13. In addition, when the iron piece detector 14 does not operate normally, the above-described test is repeatedly performed several times until the sensitivity of the iron piece detector 14 is appropriate, thereby reducing the equipment operation time.

(B) If the iron detector 14 does not operate due to inadequate sensitivity, the specimen 15 should be on top of the belt 13 and the conveyor system itself should be stopped. In this case, if the conveyor system does not stop in a timely manner, the test piece 15 may fall off to another conveyor belt or have a problem of being damaged or damaged.

Therefore, the present invention aims to solve the above-mentioned problems by providing a new device for testing the iron detector.

The present invention for realizing the above object is a guide post fixed on a frame for supporting a conveyor system equipped with a iron piece detector for detecting the iron pieces present on the rotating belt, a height adjusting member fitted to the guide post, the guide The rotating member is inserted into the post in a rotatable state and is positioned on an upper part of the height adjusting member, and one end is fixed to the rotating member, and the other end is formed of an arm to which the specimen is fixed. It was possible to test the iron detector by transferring it to.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail.

3 is a partial perspective view showing the relationship between the iron detector test device and the conveyor system according to the present invention, the iron detector test device 100 configured by the present invention is installed on the frame 10 supporting the entire conveyor system In addition, it is also shown that the iron strip detector test apparatus 100 is installed adjacent to the iron strip detector 14 described above.

Each member constituting the iron piece detector test apparatus 200 will be described in detail with reference to FIG. 4. FIG. 4 is an exploded perspective view of the iron piece detector test apparatus, and the test apparatus 100 includes a base 20 and a guide post. 30), the height adjusting member 40 and the rotating member 40 and the arm 100 is divided.

The bracket 15 is fixed by welding or the like on the frame 10 supporting the conveyor system, and the base 20 is fixed on the bracket 15. The outer circumferential surface of the base 20 is configured with a plurality of through holes 21 to which bolts are fastened, and thus the base 20 is fixed to the bracket 15 through bolts passing through the respective through holes 21. Meanwhile, the guide post fixing member 22 to which the guide post 30 is mounted is fixed to the center portion of the base 20.

Guide post 30 is a cylindrical member having a predetermined length, the lower end is fixed to the insertion hole 23 formed in the center portion of the guide post fixing member 22 described above by interference fit. The guide post 30 is fitted with a ring-shaped height adjusting member 40 and a rotating member 60 having a predetermined thickness. At this time, it is preferable to position the bearing 50 for smooth rotation of the rotating member 40 between the height adjusting member 40 and the rotating member 60 sandwiched on the guide post 30.

One side of the ring-shaped height adjusting member 40 is formed with a through hole 41 to which the fixing bolt 42 is fastened, and the fixing bolt 42 fastened to the through hole 41 is attached to the guide post 30. By contacting the natural adjustment of the height adjustment member 40 is prevented.

One side of the ring-shaped rotating member 60 is formed with a first groove 61 into which the end of the handle 70 is fitted, and an end of the arm 90 to be described later is formed on the side opposite to the first groove 61. The second groove 62 to be fitted is formed.

The arm 100 fitted into the second groove 62 of the rotating member 60 is divided into a first arm 80 and a second arm 90 rotatably coupled to the first arm 80. The first end 80A of the first arm 80 is rectangular in cross section so that no flow occurs after being fitted into the second groove 62 of the rotating member 60, and the second end 80B ) Is an empty state for the rotation of the second arm (90). That is, the second end 80B has an upper opening 81 partially cut in the longitudinal direction at the upper end in the open state, and a lower opening 82 partially cut in the longitudinal direction is also formed at the lower end. . In addition, through holes 83 through which the coupling pin 84 penetrates are formed at both sides, respectively.

The first end 90A of the second arm 90 fastened to the first arm 80 is composed of an upper member 91 and a lower member 92 having a length longer than that of the upper member 91. The through hole 93 through which the coupling pin 84 penetrates is formed. At the second end 90B of the second arm 90, a specimen fixing arm (to be described later) to which the specimen is coupled is integrally formed.

After receiving the first end 90A of the second arm 90 inside the second end 80B of the first arm 80 and inserting the coupling pin 84 into each of the through holes 83 and 93. The second arm 90 may be rotated within a predetermined range about the coupling pin 84 with respect to the first arm 80. That is, when the second arm 90 is rotated upward with respect to the coupling arm 84 with respect to the first arm 80, the upper member 91 of the first end 90A of the second arm 90 becomes the first arm. It is received in the upper opening 81 formed above the second end 80B of the 80, and the lower member 92 is separated from the lower opening 82 formed below the first arm 80 and exposed to the outside. . As such, when the second arm 90 is rotated by a predetermined angle, for example, 90 degrees (the horizontal state between the guide post 30 and the second arm 90), the upper member 91 of the second arm 90 is rotated. No further rotation of the second arm 90 is achieved by the contact of the upper surface and the marginal edge of the upper opening 81 formed on the upper portion of the first arm 80.

In this state, when the second arm 90 is rotated downward about the coupling pin 84 with respect to the first arm 80, the second arm 90 received in the upper opening 81 of the first arm 80 is formed. While the upper member 91 of the first end 90A is exposed to the outside, the lower member 92 passes through the lower opening 82 formed in the lower portion of the first arm 80 and the inside of the first arm 80. Is accepted. Continuous rotation, for example, when the first end 90A of the first arm 80 and the second arm 90 are horizontal to each other (state of FIG. 4), the lower member 92 of the second arm 90 The upper surface is in contact with the inner surface of the first arm 80 such that no further rotation of the second arm 90 is achieved.

Referring to the operation and function of the present invention configured as described above with reference to Figures 3, 4 and 5 as follows.

FIG. 5 is a perspective view illustrating an initial state of the iron detector test apparatus illustrated in FIG. 4, and the initial state of the iron detector detector 200 after assembling each member as described above, that is, the second arm 90. The specimen (S: iron piece) is fixed to the specimen fixing arm 95 formed at the second end 90B of the second arm 90 while being rotated upward and substantially in parallel with the guide post 30. Let's do it. Thereafter, when the second arm 90 is rotated about the coupling arm 84 with respect to the first arm 80, the specimen S fixed to the specimen fixing arm 95 moves on the belt 13. As the operator rotates the handle 70 in the B direction, the rotating member 60 to which the arm 100 is fixed rotates about the guide post 30, so that the specimen S moves downward to the iron detector 14. Will move. The iron piece detector 14 detects the moving specimen (S), and through this process, the iron piece detector 14 tests whether the specimen (S) is normally detected.

If the iron detector 14 does not detect the presence of the specimen S, the operator rotates the handle 70 in the opposite direction, that is, in the C direction, to return the test apparatus 200 to the initial state, that is, the state of FIG. After replacing the specimen (S) or adjust the sensitivity of the iron detector 14, and then repeat the above test until the iron detector 14 operates normally.

For convenience of use of such a test device 200 in the present invention it is possible to modify the configuration of the arm. First, as shown in FIGS. 4 and 5, the second arm 90 is bent into an L-shape to configure the specimen fixing arm 95 to which the specimen is fixed at its end 90B. Positioning it lower than the arm 90 can prevent the second arm 90 from being caught by the belt 13 to be conveyed, as well as minimizing the distance between the specimen S and the belt 13 to detect the iron piece 14. Can maintain a situation in which it can operate correctly. Here, the specimen fixing arm 95 to which the specimen S is fixed is made of a nonmagnetic material, and thus, of course, the malfunction of the iron detector can be prevented by the specimen fixing arm 95.

In addition, the arm 100 should be kept in an initial state as shown in FIG. 4 during normal operation of the conveyor system after the replacement or test of the specimen S. For this purpose, the arm fixing piece 94 is placed on the upper portion of the second arm 90. Is preferably fixed. That is, the arm fixing piece 94 is in the form of a string, the shape is made the same as the outer peripheral surface of the guide post 30 is coupled to the guide post 30 as shown in FIG. Natural downward movement can be prevented.

In addition, by adjusting the upper and lower positions of the arm 100 using the height adjusting member 40 it is possible to optimally adjust the distance between the iron piece detector 14 and the specimen (S). That is, the high information bolt 42 fastened to the through hole 41 of the height adjusting member 40 can be released to move the height adjusting member 40 up and down to adjust its position. When fastened, the end of the high information bolt 42 presses the outer circumferential surface of the guide post 30, thereby preventing natural movement of the height adjusting member 40 whose height is adjusted, as well as a rotation located above the height adjusting member 40. The height of the member 60, that is, the height of the arm 100, is adjusted to an optimal state.

The effects obtained by using the present invention as described above are as follows.

In the test, the specimen can be recovered by rotating the arm through the handle, so that the operator does not have to climb directly on the belt to remove the specimen, thereby preventing safety accidents. In addition, the time required for repeated tests to adjust the sensitivity of the iron detector can be reduced to improve the operation efficiency of the equipment, and the specimen is fixed to the end of the arm, so there is no risk of losing the specimen on the belt. It is effective in preventing the belt from being damaged by the specimen.
