DETAILED DESCRIPTION

[0018] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] As shown in the figure:

[0020] A steel processing automatic counting device comprises a mounting frame 1, a vertically slidable slide rod 2 vertically suspended in the middle of the mounting frame 1, a synchronization head 3 connected to the bottom of the slide rod 2, a light-shielding ruler 4 is installed on the top of the slide rod 2, and a plurality of groups of laser emitters 61 and photoelectric sensors 6 are installed on both sides of the light-shielding ruler 4; light-transmitting holes 41 are provided on the light-shielding ruler 4 at different distances just below the optical path of each group of laser emitters 61 and photoelectric sensors 6 (the distance is set according to the diameter of the steel bar, and the commonly used diameter is 6 / 8 / 10 / 12 mm, and other specifications are set similarly. The diameter of the light-transmitting hole 41 is about 1 m, which can avoid accidental touching of adjacent sizes, and the position of the light-transmitting hole 41 is opened according to actual production needs), each photoelectric sensor 6 is respectively connected to a counter 7, and the counter 7 increases a count each time a long pulse is generated.

[0021] Working principle: The utility model is installed above the chain plate transmission equipment after the outlet of the annealing device. When the steel bar passes through, the synchronous head 3 will be pushed upward. The pushing height is related to the diameter of the steel bar. However, in order to push more smoothly, the synchronous head 3 includes an axle frame 31 and a hollow rotating cylinder 33 horizontally installed between the axle frames 31 through a rotating shaft 32. The hollow rotating cylinder 33 can reduce resistance. When there is no steel bar, the hollow rotating cylinder 33 will rotate in contact with the chain plate, which will not generate large friction and avoid severe wear.

[0022] At this time, the upward distance of the synchronization head 3 is equal to the diameter of the steel bar, the corresponding light-shielding ruler 4 goes up the same distance, and the light-transmitting hole 41 of the corresponding diameter or specification goes up just enough to enable the corresponding photoelectric sensor 6 to receive the signal of the laser transmitter 61. Since the steel bars just leaving the factory are cut into a length of at least 10 meters, the photoelectric sensor 6 will receive a long pulse signal, and the counter 7 will increase a count at this time.

[0023] There are two situations when the photoelectric sensor 6 is used to measure other specifications. One is that the light hole 41 does not rise far enough and no signal is received. The other is that the upward distance of the light hole 41 exceeds the corresponding optical path position. Although the photoelectric sensor 6 will receive a short pulse signal when passing through the light hole 41, this pulse signal only lasts for tens of milliseconds and the corresponding calculator does not count.

[0024] In this way, each time a steel bar passes through, only the corresponding laser emitter 61 performs a count, and the specifications and quantity of the steel bars can be counted respectively. Considering the convenience of viewing, the counter can be installed on the top of the mounting frame 1, located on both sides of the slide 11.

[0025] In order to ensure the smooth operation of the slide rod 2, a slide seat 11 may be provided in the middle of the mounting frame 1, and the slide rod 2 is vertically installed in the slide seat 11 and slides along it. At the same time, fixed plates 5 are symmetrically provided on both sides of the slide seat 11. The top of the fixed plate 5 is connected by a horizontal plate 51 with a groove 511, and the top of the shading ruler 4 passes through the groove 511. The laser emitter 61 and the photoelectric sensor 6 are respectively installed on the inner side of the fixed plates 5 on both sides.

[0026] In order to reduce the height of the light-shielding ruler 4, two groups of laser emitters 61 and photoelectric sensors 6 are installed at the same height of the fixed plate 5 and installed in parallel horizontally.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
