Description
Technical Field
[0001] The present application relates to the technical field of gates, and in particular to a vertical motion gate assembly. Background Art
[0002] At present, with the popularization of various self-service terminal equipment, the operability and safety of the equipment are increasingly valued. Most self-service equipment is equipped with gates to prevent foreign objects from invading the equipment channel, etc., and based on safety considerations, the gates need to be equipped with anti-pinch devices.
[0003] At present, most of the anti-pinch devices of self-service terminal equipment on the market use elastic elements and mechanical structures to prevent pinching or reduce the damage caused by pinching. When the gate plate of the existing anti-pinch device is closed from bottom to top, if the operator does not withdraw his hand from the channel between the gate plate and the self-service terminal equipment in time, the gate plate will squeeze the operator's hand and push the anti-pinch baffle to rotate clockwise. The anti-pinch baffle blocks the anti-pinch sensor, and the motor stops and then opens the gate plate to realize the anti-pinch function. Due to the limitation of spatial structure, this kind of gate anti-pinch device has a complex structure and cumbersome assembly, and it cannot completely avoid damage to the hand, but can only reduce pinching. However, the existing gate has complex movements, and the anti-pinch effect is unstable or prone to failure. Summary of the invention
[0004] In order to simplify the structure of the valve and improve the anti-pinching effect of the valve, the present application provides a vertical motion gate assembly.
[0005] The vertical motion gate assembly provided in this application adopts the following technical solution:
[0006] A vertical motion gate assembly comprises a base frame, a gate plate, a vertical limiter, a driving member and a detection system;
[0007] The base frame is used to connect with the self-service equipment, the gate plate is arranged on the side of the base frame away from the self-service equipment, the vertical limit members are arranged at the left and right ends of the base frame, the two sides of the gate plate are slidably connected with the vertical limit members, and the driving member includes a driving motor, a driving gear installed on the shaft end of the driving motor, and a driving rack fixed on the back side of the gate plate for meshing with the driving gear;
[0008] The detection system includes through-beam sensors arranged up and down in the channel and a current detection sensor for detecting the current of the driving motor, the through-beam sensor is used to emit a through-beam laser, and the control system is used to prevent the driving component from starting when the through-beam sensor detects that a foreign object blocks the through-beam laser, and the control system is used to control the driving motor to stop when the current detection sensor detects that the current of the driving motor increases abnormally.
[0009] By adopting the above technical solution, the driving motor drives the driving gear to rotate, thereby driving the gate plate to move up and down along the guide rail. By arranging a through-beam sensor in the channel, the through-beam sensor is used to emit a through-beam laser. When a human hand does not exit the channel in time, the human hand will block the through-beam laser, so that the receiving end of the through-beam sensor cannot receive the signal. When the control system still does not receive the feedback signal from the receiving end of the through-beam sensor after a certain period of time, it will not send a start signal to the driving motor, thereby not controlling the gate plate to close, thereby avoiding pinching of the human hand. In addition, by adding a current detection sensor for detecting the current of the driving motor, when the motor feedback current increases abnormally (when the gate plate is stuck or pinches the human hand), the gate plate stops moving, thereby avoiding further pinching of the human hand.
[0010] Preferably, it also includes position detection sensors for respectively detecting the upper and lower limit positions of the gate plate, and the position detection sensors are respectively arranged corresponding to the top and bottom of the gate plate.
[0011] By adopting the above technical solution, the exact position of the gate plate can be monitored in real time through sensors, so that the movement of the gate plate can be controlled more accurately to ensure that it stays accurately at the predetermined extreme position; once the gate plate approaches or reaches the limit of its movement, the sensor can provide instant feedback, thereby triggering the control system to take corresponding protective measures to prevent equipment damage or safety accidents caused by exceeding the travel range, thereby effectively improving safety.
[0012] Preferably, the position detection sensor is fixed on the base frame via a detection bracket, the detection bracket is connected to the base frame via a horizontally extending fixing block, the detection bracket extends along the length direction of the gate plate, and the two position detection sensors are respectively fixed at both ends of the detection bracket.
[0013] By adopting the above technical solution, the detection bracket is reasonably arranged, and the position detection sensors are set at the upper and lower ends of the detection bracket, so as to facilitate the measurement of the distance the gate plate moves up and down.
[0014] Preferably, the torque of the drive motor is 1 to 2 times the weight of the gate plate.
[0015] By adopting the above technical solution, the torque of the driving motor is designed to be 1 to 2 times the weight of the gate plate, which ensures the smooth movement of the gate plate and reduces the probability of pinching people's hands when the gate plate is closed incorrectly. It can serve as the third line of defense for the anti-pinch function of this application.
[0016] Preferably, the torque of the drive motor is 1.5 times the weight of the gate plate.
[0017] By adopting the above technical solution, the torque of the driving motor is 1.5 times the weight of the gate plate. This force can ensure that the gate plate runs smoothly. At the same time, if the shooting sensor fails and the gate plate is closed by mistake, this force is not enough to pinch people's hands and will not even cause pain.
[0018] Preferably, the vertical limiting member comprises a guide rail fixed on the base frame, and a guide rail seat cooperating with the guide rail is fixed on the side of the gate plate facing the base frame.
[0019] By adopting the above technical solution, through the cooperation of the guide rail and the guide rail seat, the gate plate and the base frame form a horizontal limit, but a position relationship in which they can slide up and down, thereby ensuring the smooth sliding of the gate plate.
[0020] Preferably, the guide rail is connected to the base frame via a guide rail fixing frame vertically fixed to the base frame.
[0021] By adopting the above technical solution and providing a guide rail fixing frame, the installation of the guide rail can be achieved, and it is ensured that after the gate plate is installed, the gate plate is slidably arranged on the front side of the base frame.
[0022] Preferably, a fixing bracket for mounting the driving motor is mounted on the base frame, and the fixing bracket extends in a direction perpendicular to the gate plate.
[0023] By adopting the above technical solution, it is convenient to reasonably arrange the space between the base frame and the gate plate, so as to realize the installation and fixation of the drive motor.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. This application sets up a detection system, namely, a beam sensor for detecting whether there are foreign objects in the channel and a current detection sensor installed on the drive motor. When the foreign objects in the channel block the beam laser emitted by the beam sensor, the control system will not start the drive motor, reducing the risk of the gate plate erroneously descending and pinching a person's hand. If the gate plate erroneously pinches a person's hand, it will cause the current of the drive motor to increase abnormally. After the current detection sensor detects the abnormal increase in the current of the drive motor, it controls the drive motor to stop, preventing the gate plate from continuing to apply pressure to the person's hand, thereby preventing further pinching of the person's hand.
[0026] 2. By designing a position detection sensor to detect the upper and lower limit positions of the gate plate, the movement of the gate plate can be controlled more accurately to ensure that it stays accurately at the predetermined limit position;
[0027] 3. By reasonably designing the torque of the driving motor, it can be ensured that the gate plate runs smoothly. At the same time, if the shooting sensor fails and the gate plate is closed incorrectly, the force is not enough to pinch people's hands, and it will not even cause pain, thus avoiding pinching people's hands.

[0033] The following is combined with Figure 1-4 This application is described in further detail.
[0034] The present application embodiment discloses a vertical motion gate assembly. Figure 1 The vertical motion gate assembly includes a base frame 1, a gate plate 2, a vertical limit member 3, a driving member 4 and a detection system 5.
[0035] Reference Figure 1-Figure 4 , the base frame 1 is used to connect with the self-service equipment, and the gate plate 2 is arranged on the side of the base frame 1 away from the self-service equipment. The vertical limiter 3 is arranged at the left and right ends of the base frame 1, and the two sides of the gate plate 2 are slidably connected to the vertical limiter 3, so that the gate plate 2 can slide up and down along the base frame 1. Specifically, in the present application, the vertical limiter 3 includes a guide rail 31 fixed on the base frame 1, and a guide rail seat 32 that cooperates with the guide rail 31 is fixed on the side of the gate plate 2 facing the base frame 1. Through the cooperation between the guide rail 31 and the guide rail seat 32, the gate plate 2 and the base frame 1 form a lateral limit, but a positional relationship that can slide up and down, to ensure the smooth sliding of the gate plate 2. The guide rail 31 is connected to the base frame 1 through a guide rail 31 fixing frame vertically fixed on the base frame 1 to ensure the smooth installation of the guide rail 31.
[0036] The driving member 4 is used to drive the gate plate 2 to slide up and down, and the driving member 4 includes a driving motor 41, a driving gear 42 installed at the shaft end of the driving motor 41, and a driving rack 43 fixed to the back side of the gate plate 2 for meshing with the driving gear 42. The driving motor 41 is started to drive the driving gear 42 to rotate synchronously, and the driving gear 42 drives the driving rack 43 and the gate plate 2 to slide up and down. The driving motor 41 is installed on the base frame 1 through a fixing bracket 9, and the fixing bracket 9 extends in a direction perpendicular to the gate plate 2.
[0037] The detection system 5 includes a beam sensor 51 arranged up and down in the channel and a current detection sensor for detecting the current of the drive motor 41. The beam sensor 51 is used to emit a beam laser, and the control system is used to prevent the drive motor 41 from starting when the beam sensor 51 detects that the beam laser is blocked by a foreign object. That is, when a human hand does not exit the channel in time, the human hand will block the beam laser, so that the receiving end 512 of the beam sensor 51 cannot receive the signal. When the control system still does not receive the feedback signal from the receiving end 512 of the beam sensor 51 after a certain period of time, it will not send a start signal to the drive motor 41, so as not to control the gate plate 2 to close, so as to avoid pinching the human hand. And when the gate plate 2 is stuck or pinches the human hand, the control system is used to control the drive motor 41 to stop when the current detection sensor detects that the current of the drive motor 41 increases abnormally. Thereby further reducing the probability of the gate plate 2 failing and pinching the human hand.
[0038] In order to further reduce the probability of accidental pinching of human hands, the torque of the drive motor 41 is designed to be 1 to 2 times the weight of the gate plate 2. Preferably, the torque of the drive motor 41 is 1.5 times the weight of the gate plate 2. This force can ensure that the gate plate 2 does not jam, and if the through-shooting sensor 51 fails and the gate plate 2 is mistakenly closed, this force is not enough to pinch a human hand, and even does not cause pain.
[0039] The present application also includes a position detection sensor 52 for respectively detecting the upper and lower limit positions of the gate plate 2, and the position detection sensor 52 is respectively set corresponding to the top and bottom of the gate plate 2. Specifically, the position detection sensor 52 is fixed to the base frame 1 through a detection bracket 6, and the detection bracket 6 is connected to the base frame 1 through a horizontally extending fixed block 7. The detection bracket 6 extends along the length direction of the gate plate 2, and two position detection sensors 52 are respectively fixed at both ends of the detection bracket 6. By monitoring the exact position of the gate plate 2 in real time through the position detection sensor 52, the movement of the gate plate 2 can be more accurately controlled to ensure that it stays accurately at the predetermined limit position; once the gate plate 2 approaches or reaches the limit of its movement, the sensor can provide instant feedback, thereby triggering the control system to take corresponding protective measures to prevent equipment damage or safety accidents caused by exceeding the travel range, thereby effectively improving safety.
[0040] The implementation principle of a vertical motion gate assembly in the embodiment of the present application is as follows: when the self-service device receives a signal to raise the gate plate 2, the drive motor 41 starts to drive the gate plate 2 to rise upward. After the position detection sensor 52 detects that the gate plate 2 has moved into position, it sends a signal to the control system, and the control system controls the drive motor 41 to stop, and the gate plate 2 stops at the current position. After that, a person reaches into the passage to take the items in the self-service device. In the process of taking the items, the person's hand will block the laser beam emitted by the transmitting end 511 of the beam sensor 51, so that the receiving end 512 of the beam sensor 51 cannot receive the laser beam. At this time, the control system cannot receive the electrical signal emitted by the beam sensor 51, and the control system does not send a signal to the drive motor 41, so that the gate plate 2 will not drop when there is a foreign object in the passage, avoiding pinching of the person's hand. When the gate plate 2 mistakenly pinches the person's hand or is stuck, the current detection sensor detects that the current on the drive motor 41 increases abnormally, and then controls the drive motor 41 to stop, avoiding the gate plate 2 from continuing to move and further pinching the person's hand. By setting the torque of the driving motor 41 , if the gate plate 2 pinches a person's hand, the downward force of the gate plate 2 is not enough to pinch the person's hand, thereby further reducing the probability of pinching the person's hand.
[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
