[0014] Example 1: see Figure 1 and Figure 2The application discloses a ruler body sorting machine for level ruler production, which comprises two pairs of conveying belts 100, a feeding chute 200, two pairs of pushing devices 300 and a turning mechanism 400. The feeding chute is arranged on the upper side of the front end of the two pairs of conveying belts. The feeding chute is composed of a front inclined plate 210, a rear limiting plate 220 and two side plates 230, and defines a feeding opening 240 and an outlet 250. The ruler body 10 can be put into the feeding opening of the feeding chute and slide from the outlet to the two conveying belts. Two sorting rollers, namely a first sorting roller 501 and a second sorting roller 502, are arranged on the rear side of the feeding chute and above the conveying belts. The gap between the first sorting roller and the conveying belt is smaller than the gap between the rear limiting plate and the conveying belt. The height of the second sorting roller is lower than that of the first sorting roller. The sorting roller is composed of a shaft body 510 and a plurality of elastic sheets 520 arranged on the shaft body in a circumferential array. The sorting roller is driven by a motor to rotate at a constant speed. The tangential moving direction of the bottom of the sorting roller is opposite to the conveying direction of the conveying belt. The turning mechanism is arranged at the rear end of the conveying belt and comprises a stepping motor 430, a rotating shaft 410 and two rotating discs 420 coaxially arranged on the rotating shaft. Six open grooves 421 are arranged on the rotating disc in a circumferential array. The ruler body on the conveying belt can slide into the open groove. The sorting machine is further provided with a proximity sensor 20 capable of detecting whether the ruler body completely slides into the open groove and a laser sensor 30 capable of detecting whether there is a gap on the ruler body. The two pairs of pushing devices are arranged on the front and rear sides of the rotating disc. The pushing device on the other side of the conveying belt is further provided with a guide groove 40. The sliding end of the guide groove is provided with an expanded opening. The pushing device can push the ruler body in the open groove into the guide groove.

[0015] The operation principle of the embodiment is as follows: after the ruler bodies are machined, they are stored in a unified length direction; workers only need to put the ruler bodies into the feeding groove at regular time, and need to pay attention to the direction of the two ends of the ruler body when feeding, that is, the two ends of the ruler body are opposite to the two side plates, and the distance between the two side plates is slightly greater than the length of the ruler body; then the ruler bodies are stacked in the feeding groove, and the ruler bodies at the bottom are transmitted backward along with the conveying belt; in the transmission process, the material arranging roller drives the elastic sheet to rotate continuously; at this time, the distance between the material arranging roller and the conveying belt is only slightly greater than the thickness of the ruler body in the flat state, so when the stacked ruler body or the ruler body in the vertical state passes, the material arranging roller can re-arrange the posture of the ruler body, so that the ruler body can only pass in the flat state; then the flat ruler body is conveyed into the open groove in front of the turning mechanism; the proximity sensor can detect that the ruler body has completely entered the open groove; at this time, the laser sensor is triggered to detect; the laser path emitted by the laser sensor passes through the mounting groove in the middle of the ruler body, so when the laser sensor detects the signal, it indicates that the direction of the ruler body is correct; the pushing device in front of the turning mechanism can push the ruler body into the corresponding guide groove; the ruler body in the guide groove is conveyed to the automatic installation equipment of the level ruler; if the laser sensor cannot detect the light signal, it indicates that the light signal is blocked by the ruler body, that is, the posture of the ruler body is not correct; at this time, the turning mechanism starts to act, and turns a certain angle, so that the empty open groove is turned to the rear end of the conveying belt to receive the new ruler body, and the ruler body that needs to be turned will be shifted backward until the turning is completed; the ruler body that has completed the turning will also be shifted to the corresponding guide groove under the pushing of the corresponding pushing device. Therefore, the embodiment can automatically sort and correct the posture of the ruler body, recognize the front and back directions of the flat state, and automatically turn the ruler body to fix the direction for output, which is convenient for adapting to the existing automatic installation equipment of the level ruler.

[0016] See Figure 2 The embodiment also includes two limiting cylinders 600, which are arranged on the two sides of the two conveying belts and located in front of the turning mechanism; the pushing rod of the limiting cylinder is provided with a pressing block 610. The action of the limiting cylinder is also triggered by the proximity sensor; after the pressing blocks of the two limiting cylinders are pushed out, the positions of the ruler bodies on the conveying belt can be corrected, so that the ruler bodies are located in the middle; in this way, when the ruler body enters the open groove, the ruler body will not interfere with the pushing device in reality.

[0017] See Figure 2 The pushing device is composed of a pushing cylinder 310 and a pushing block 320 fixed on the pushing rod of the pushing cylinder.

[0018] See Figure 1 One side of the open groove is provided with a concave notch 422, and the rotating disc can be rotated to make the notch opposite to the positions of the pushing blocks on the two pushing devices. The end face of the ruler body is a hollow structure; in order to increase the contact area between the pushing block and the end face of the ruler body, the embodiment realizes reliable contact between the pushing block and the end face of the ruler body by arranging the notch on the open groove.

[0019] It will be apparent to those skilled in the art that modifications can be made to the embodiments described above without departing from the scope of the application. Such modifications are to be considered within the scope of the application.
