Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 and 2, the shuttle car safeguard system of the present embodiment can be used to safeguard the shuttle car 1 and the personnel. The shuttle car 1 is disposed on a first guide rail 2 and a second guide rail 3 which are parallel to each other, and linearly reciprocates along the first guide rail 2 and the second guide rail 3. The system includes a plurality of baffles 4, a first laser sensor 5, a second laser sensor 6, a third laser sensor 7, and a PLC (Programmable Logic Controller).
Wherein a plurality of baffles 4 are respectively installed at both ends of the first guide rail 2 and/or the second guide rail 3. Preferably, two ends of the first guide rail 2 and the second guide rail 3 are respectively provided with a baffle 4, the baffle 4 on the first guide rail 2 extends towards the second guide rail 3, and the baffle 4 on the second guide rail 3 extends towards the first guide rail 2. That is, the baffles 4 each extend toward the inside of the guide rail. The baffle 4 can play the guard action to the tray of shuttle 1 conveying, avoids the tray to break away from the guide rail and drops.
The first laser sensor 5 is provided on the shuttle car 1, and is configured to output the first laser beam 51 to the barrier 4, in other words, the first laser beam 51 is output from the first laser sensor 5 and then irradiated on the barrier 4. The first laser beam 51 is parallel to the first guide rail 2 and the second guide rail 3.
The second laser sensor 6 is disposed on the shuttle car 1 on a side of the shuttle car 1 close to the first guide rail 2, and is configured to output the second laser beam 61 to an inner side of the second guide rail 3, or the second laser beam 61 output from the second laser sensor 6 is irradiated on the inner side of the second guide rail 3. An included angle is formed between the second laser beam 61 and the second guide rail 3, and the included angle is between 15 degrees and 20 degrees.
The third laser sensor 7 is disposed on the shuttle car 1 on a side of the shuttle car 1 close to the second guide rail 3, and is configured to output the third laser beam 71 to an inner side of the first guide rail 2, that is, the third laser beam 71 output from the third laser sensor 7 is irradiated on the inner side of the first guide rail 2. An included angle is formed between the third laser beam 71 and the second guide rail 3, and the included angle is between 15 degrees and 20 degrees.
PLC respectively with shuttle 1, first laser sensor 5, second laser sensor 6 and third laser sensor 7 electric connection. The PLC is configured to receive signals fed back from the first laser sensor 5, the second laser sensor 6, and the third laser sensor 7, and perform calculations to control the shuttle car 1 to decelerate and/or stop according to the received signals. Specifically, when the first laser sensor 5 detects that the length of the first laser beam 51 output by the first laser sensor is smaller than or equal to a first preset value, the first laser sensor 5 triggers and transmits the signal to the PLC so that the PLC controls the shuttle car 1 to decelerate; when the first laser sensor 5 detects that the length of the first laser beam 51 is smaller than or equal to a second preset value, the first laser sensor 5 triggers and transmits the signal to the PLC so that the PLC controls the shuttle car 1 to stop, and the second preset value is smaller than the first preset value; when the second laser sensor 6 detects that the length of the second laser beam 61 is smaller than a third preset value, the second laser sensor triggers and transmits the signal to the PLC so that the PLC controls the shuttle car 1 to stop; when the third laser sensor 7 detects that the length of the third laser beam 71 is less than the fourth preset value, it triggers and transmits the signal to the PLC so that the PLC controls the shuttle car 1 to stop.
With the above structure, in the system of the embodiment, the first laser sensor 5 detects the length of the first laser beam 51 to determine whether the shuttle car 1 is close to the baffle 4, and transmits the signal to the PLC, and the PLC first controls the shuttle car 1 to decelerate according to the received signal, and then stops under the control of the PLC after the shuttle car 1 decelerates for a certain distance; the second laser sensor 6 detects the length of the second laser beam 61 to determine whether there is an obstacle (human body or object) inside the second guide rail 3, and normally, as the shuttle car 1 moves on the guide rail (when the length of the first laser beam 51 is greater than the second setting), the distance between the second laser sensor 6 and the second guide rail 3 is not changed, so the length of the second laser beam 61 is kept unchanged, when an obstacle appears between the second laser sensor 6 and the second guide rail 3 along the light direction of the second laser beam 61, the second laser beam 61 cannot be irradiated on the second guide rail 3, that is, the second laser sensor 6 detects that the second laser beam 61 is shortened (less than a third preset value), and at this time, the second laser sensor 6 transmits the signal to the PLC so that the PLC controls the shuttle car 1 to stop. The working principle of the third laser sensor 7 is substantially the same as that of the second laser sensor 6, and will not be described in detail here.
By adopting the scheme, the system of the embodiment can ensure that the shuttle car 1 has longer safety protection distance, so that the shuttle car 1 can be stopped before colliding with obstacles such as human bodies, and the safety and the stability of the operation of the shuttle car 1 are improved.
The second laser sensor 6 and/or the third laser sensor 7 may also be used to detect whether the end of the first guide rail 2 and/or the second guide rail 3 has the baffle 4, so as to prevent the first laser sensor 5 from being unable to detect the distance between the shuttle 1 and the baffle 4 by outputting the first laser beam 51 to the baffle 4 when the baffle 4 on the first guide rail 2 and the second guide rail 3 drops or is neglected to be installed. Specifically, the PLC controls the shuttle car 1 to decelerate and/or stop when the length of the second laser beam 61 is greater than the third preset value and the length of the first laser beam 51 is greater than the first preset value; the PLC controls the shuttle car 1 to decelerate and/or stop when the length of the third laser beam 71 is greater than the fourth preset value and the length of the first laser beam 51 is greater than the first preset value.
More specifically, when the first guide rail 2 and the second conductor are not provided with the baffle 4 at the same end, the first laser sensor 5 cannot detect that the length of the first laser beam 51 is smaller than the first preset value, so the PLC cannot control the shuttle car 1 to decelerate, when the shuttle car 1 runs to exceed the ends of the first guide rail 2 and the second guide rail 3, the second laser beam 61 is separated from the second guide rail 3 and/or the third laser beam 71 is separated from the first guide rail 2 (the second laser beam 61 emitted by the second laser sensor 6 cannot generate a light spot on the second guide rail 3, the third laser beam 71 emitted by the third laser sensor 7 cannot generate a light spot on the first guide rail 2), at the moment, the length of the second laser beam 61 is larger than the third preset value and/or the length of the third laser beam 71 is larger than the fourth preset value, the second laser sensor 6 and/or the third laser sensor 7 transmit the signal to the PLC, the PLC controls the shuttle 1 to decelerate and then stop.
By adopting the scheme, the safety protection system can prevent the shuttle car 1 from falling off from the guide rails when the end baffles 4 of the first guide rail 2 and the second guide rail 3 fall off or are neglected to be loaded.
Specifically, the safety protection system of this embodiment may further include an alarm electrically connected to the PLC, and when the PLC receives a signal that the second laser beam 61 is not equal to the third preset value and/or the third laser beam 71 is not equal to the fourth preset value (i.e., when the shuttle 1 encounters an obstacle or is about to disengage from the guide rail during the operation), the PLC may control the alarm to issue an alarm.
Specifically, the spot diameter of the second laser beam 61 and/or the third laser beam 71 is less than or equal to 5mm, in other words, when the diameter of the obstacle reaches 5mm, the obstacle detection signal of the safety protection system of the embodiment may be triggered.
Referring to fig. 1 and 2, the safety shield system of the present embodiment may further include a fourth laser sensor 8 provided on the shuttle car 1. The fourth laser sensor 8 is used for outputting a fourth laser beam 81 in an oblique direction, and the angle of the fourth laser beam 81 inclining upwards relative to the horizontal plane is between 10 and 15 degrees. The fourth laser sensor 8 is used for sensing whether a tray (not shown) which is already placed on the guide rail is in front of the shuttle car 1, when the tray is on the guide rail, the fourth laser beam 81 irradiates on the tray, the fourth laser sensor 8 can detect that the length of the fourth laser beam 81 is shortened, and when the length of the fourth laser beam 81 is shortened to a certain value, namely the length of the fourth laser beam 81 is smaller than a fifth preset value, the signal can trigger the PLC so that the PLC controls the shuttle car 1 to stop, the shuttle car 1 is stopped at a safe position, and the shuttle car 1 is prevented from colliding with the tray in front.
The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
