Description

Technical Field

[0002] At present, financial self-service equipment uses various forms of gates to protect the device channel dispensing ports such as banknotes or bills. When a medium is to be sent to the temporary storage area of ​​the self-service equipment, the gate opens, and the customer reaches into the temporary storage area inside the equipment to take out the medium such as banknotes or bills. The gate closes after the temporary storage area exit position sensor does not sense the customer's fingers or other objects within about 30 seconds. If the customer reaches in and triggers the sensor during the gate closing process, the gate will open, and then try to close the gate after there is no object blocking it. The closing force depends on the motor.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] like Figure 1-Figure 6 As shown, an anti-pinch gate mechanism provided in an embodiment of the present application is now described. The anti-pinch gate mechanism is arranged on a financial self-service device. Specifically, the anti-pinch gate mechanism includes: a frame, a gate 15, a motor 18, a self-locking component 21 and a torque limiter 214. The frame is provided with a gate for users to take things; the gate 15 is slidably arranged on the frame, and the gate can be opened and closed; the motor 18 is arranged on the frame, the motor 18 is connected to the torque limiter 214, the torque limiter 214 is connected to the self-locking component 21, and the gear 221 of the self-locking component 21 is meshed with the rack 16 on the gate 15. When the motor 18 works, it drives the self-locking component 21 to rotate through the torque limiter 214, and when the self-locking component 21 rotates, it drives the gear 221 to rotate, and the gear 221 drives the rack 16 to do linear reciprocating motion, thereby driving the gate 15 to open or close. The torque limiter 214 is a mechanical transmission overload protection device. Once the applied force is greater than the set torque, the device immediately and automatically cuts off the transmission, and can start overload protection for the output torque of the motor 18, which can not only prevent the user's hand from being pinched, but also protect the motor 18 from being damaged. In this embodiment, the torque limiter 214 has the function of limiting the torque in both positive and negative directions. Its structure is divided into an outer ring 2141 and an inner ring 2142. The inner and outer rings can rotate relative to each other. The inner ring 2142 is engaged with the second pin 213 on the worm 211 below to maintain relative fixation with the worm 211. The outer ring 2141 is connected to the pulley 215.

[0030] Specifically, the frame includes: a left bracket 11, a right bracket 12, a fixing rod 13 and a fixing plate 14. The left bracket 11 and the right bracket 12 are arranged in parallel and spaced apart, the two ends of the fixing rod 13 are respectively connected to one end of the left bracket 11 and the right bracket 12, and the fixing plate 14 is installed at the other end of the left bracket 11 and the right bracket 12, so that the entire frame is firm; and the interval between the fixing plate 14 and the fixing rod 13 is a gate; the two sides of the gate 15 are slidably arranged on the left bracket 11 and the right bracket 12. The gate 15 is provided with a sheet metal baffle for shielding the sensor during the opening and closing process of the gate 15. Specifically, the left bracket 11 and the right bracket 12 are provided with a guide rail 17 for slidingly installing the gate 15. The guide rail 17 adopts a slotted structure, and rollers are arranged in the slot, which facilitates the sliding of the gate 15.

[0031] In this embodiment, the self-locking component 21 adopts a worm gear assembly with self-locking properties. Specifically, the self-locking component 21 includes: a base 210, a worm 211 rotatably set on the base 210, and a worm wheel 219 rotatably set on the base 210 and meshingly connected with the worm 211. The worm 211 is transmission-connected to the torque limiter 214, and the gear 221 is transmission-connected to the worm wheel 219; the lead angle of the worm 211 is smaller than the equivalent friction angle between the meshing gear teeth, thereby achieving the self-locking property of the worm wheel 219 and worm 211 assembly, that is, only the worm 211 drives the worm wheel 219 to rotate, and the worm wheel 219 cannot drive the worm 211 to rotate, so that the external push on the gate 15 cannot drive the worm wheel 219 to rotate, thereby achieving the self-locking of the gate 15.

[0032] In this embodiment, the base 210 is a rectangular frame structure, and a corresponding installation window is provided on the fixing plate 14. A first bearing seat 212 is convexly provided on the upper surface of the base 210, and both ends of the worm 211 are rotatably provided on the first bearing seat 212. A second bearing seat 217 is convexly provided on the lower surface of the base 210, and a mounting shaft 216 of a worm wheel 219 is rotatably provided on the second bearing seat 217; the worm wheel 219 and the worm 211 are meshed in the middle of the frame of the base 210. Specifically, the worm wheel 219 is fixed on the mounting shaft 216 by a fastening screw 218; the gear 221 is installed on one end of the mounting shaft 216 by a first pin 220, and rotates synchronously with the mounting shaft 216. The inner ring of the torque limiter 214 is fixed on the worm 211 by a second pin 213, and the outer ring of the torque limiter 214 is connected to the pulley 215, and the pulley 215 is connected to the motor 18 by a synchronous belt 222.

[0033] In this embodiment, a first anti-pinch sensor 23 and a second anti-pinch sensor 24 for detecting foreign objects are provided at intervals on the left bracket 11 and / or the right bracket 12, and the first anti-pinch sensor 23 and the second anti-pinch sensor 24 are provided at intervals along the movement direction of the gate 15. When the first anti-pinch sensor 23 and / or the second anti-pinch sensor 24 sense the user's hand or foreign objects, the motor 18 rotates in the opposite direction, so that the gate 15 is converted from a closed operating state to an open operating state. In this embodiment, an opening sensor for detecting the opening of the gate 15 and a closing sensor for detecting the closing of the gate 15 are provided at intervals on the fixed plate 14. When the gate 15 is in an open state, the sheet metal baffle blocks the opening sensor, and when the gate 15 is in a closed state, the sheet metal baffle blocks the closing sensor.

[0034] In this embodiment, after many experiments, when the force of the gate 15 pinching the hand is 10N, the customer can clearly feel the pressure on the finger, but at the same time there will be no pain and no injury. Therefore, in this embodiment, when the resistance of the gate 15 is 10N, the torque limiter 214 is triggered to prevent the user's hand from being pinched.

[0035] In this embodiment, the opening process of the gate 15 is as follows: in the initial position, the gate 15 is in a closed state, at which time the sheet metal baffle is located at the closing sensor. After receiving the opening information instruction from the financial self-service device, the control panel 20 controls the motor 18 to rotate forward, and drives the pulley 215 to rotate through the synchronous belt 222. The pulley 215 drives the worm 211 to rotate through the torque limiter 214. The worm 211 drives the worm wheel 219 to rotate, and the worm wheel 219 drives the gear 221 to rotate. The gear 221 drives the rack 16 to move, thereby realizing the gradual opening of the gate 15. When the sheet metal baffle of the gate 15 moves to the opening sensor 19, the gate 15 is opened in place and the motor 18 stops working.

[0036] In this embodiment, the closing process of the gate 15: in the initial position, the gate 15 is in the open state. At this time, the sheet metal baffle of the gate 15 is located at the opening sensor. After receiving the gate 15 closing instruction from the financial self-service device, the control board 20 controls the motor 18 to reverse, and drives the pulley 215 to rotate through the synchronous belt 222. The pulley 215 drives the worm 211 to rotate through the torque limiter. The worm 211 drives the worm wheel 219 to rotate, and the worm wheel 219 drives the gear 221 fixed on the mounting shaft 216 to rotate. The gear 221 engages with the rack 16 fixed on the gate 15, thereby driving the gate 15 to gradually close. When the sheet metal baffle reaches the closing sensor 22, the gate 15 is closed in place and the motor 18 stops working.

[0037] During the closing process of the gate 15, if a customer extends his hand to cover or uses a foreign object to cover any one of the first anti-pinch sensor 23 and the second anti-pinch sensor 24, the sensing signal is transmitted to the control system of the financial self-service device, which controls the motor 18 from reverse rotation to forward rotation and fully opens the gate 15. When the blocking signals of the first anti-pinch sensor 23 and the second anti-pinch sensor 24 disappear, there is a delay of a certain time, and the motor 18 starts to reverse, and the gate 15 continues to close.

[0038] During the closing process of the gate 15, if the first anti-pinch sensor 23 and the second anti-pinch sensor 24 are damaged or abnormally misreported, or the position where the customer puts his hand in happens to be in the blind spot of the sensor, the gate 15 will continue to close until the gate 15 feels a significant resistance of about 10N, and the torque limiter 214 starts overload protection. At this time, the motor 18 continues to rotate, but the pulley 215 cannot drive the torque limiter 214 to drive the worm wheel 219 and the worm 211 to move. The gate 15 will temporarily stop at the blocked position. After a certain delay, when the control system determines that the gate 15 has not reached the predetermined closing position, it controls the motor 18 to change from reverse rotation to forward rotation, and fully opens the gate 15, and then continues to determine whether the anti-pinch sensor is blocked. If it is not blocked, the motor 18 starts to reverse, and the gate 15 continues to close. If there is no additional resistance during the closing process, until the sheet metal baffle of the gate 15 reaches the closing sensor 22, the gate 15 is closed in place and the motor 18 stops.

[0039] In this embodiment, since the maximum torque outputted finally depends on the torque limiter 214, the selection range of the motor 18 is wider, which facilitates the universalization of the motor 18. At the same time, when the torque limiter 214 is overloaded, the inner ring and the outer ring can rotate relative to each other, thereby protecting the motor 18 from being suffocated and preventing the synchronous belt 222 from skipping teeth.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
