Description

Technical Field

[0001] The present invention relates to the technical fields of intelligent lockers and self-service book borrowing and returning devices, and particularly relates to an automatic door opening device for multiple door cabinets and an entire device thereof. Background Art

[0002] In the fields of intelligent lockers or self-service book borrowing and returning devices, many application scenarios require multiple independent door cabinets, and each door cabinet is locked separately to meet the requirements of precisely controlling personnel to take and place items or books.

[0003] The current general solution is shown in Figure 1 and Figure 2 It has multiple door cabinet units, and the structure of each door cabinet unit is the same. An automatic door opening device is installed at the position C shown in Figure 1 The structure of each automatic door opening device is shown in Figure 2 It has a small door 80, and the small door 80 is controlled by a separate electric control lock 81. The electric control lock 81 has positive and negative control leads 82. When receiving an electrical signal, the tongue 83 in the electric control lock 81 rotates clockwise or counterclockwise around the rotation shaft 84 (as shown by the arrow in Figure 2 ) to unlock and eject the small door 80. In an intelligent device, it is usually necessary to detect the opening and closing states of the door. Therefore, a sensor is also provided in the electric control lock 81, generally a touch switch (not shown in the attached drawings). Through a mechanical structure, the closed and open states of the door 80 respectively correspond to the conduction or off states of the two output leads 85 of the touch switch.

[0004] In the prior art, the electric control lock 81 and each small door 80 have a one-to-one matching relationship, the device is complex, and the cost is high. Taking a certain model of 120-book self-service book borrowing and returning machine as an example, the description is as follows:

[0005] 1. It has 120 door cabinets;

[0006] 2. Each door cabinet has 1 electric control lock, each electric control lock has positive and negative control leads, and each electric control lock also has two signal output leads. A total of 480 wires need to be connected to the control system one by one. The wiring is arranged densely, and there are many repeated installation processes, which are complex. The material and labor costs remain high;

[0007] 3. With so many wire connections, the use reliability is poor. Coupled with a certain failure ratio of the electric control lock itself, the actual use reliability of the product is low, and functional abnormalities are likely to occur during natural use.

[0008] It should be noted that the information disclosed in this background art is only intended to enhance the overall understanding of the present invention, for understanding the background in which the inventor generated the inventive concept or discovered the technical problem, and should not be regarded as an admission or an indication in any form that this information constitutes the prior art known to those skilled in the art. Summary of the Invention

[0009] In view of this, to solve the above technical problems, the object of the present invention is to provide an automatic door opening device for multiple cabinets and the entire equipment, which solves the problems of complex structure installation, wire connection, high cost, and high failure rate at present, and has the technical effects of reducing the installation complexity, reducing wiring, saving costs, and improving the product reliability.

[0010] The technical solution adopted is as follows:

[0011] An automatic door opening device for multiple cabinets of the present invention includes:

[0012] An X-axis moving device, which is used to provide movement in the X-axis direction;

[0013] An unlocking assembly, which contains a key and an electric device capable of rotating the key, and is fixed on the X-axis moving device and moves with the X-axis moving device;

[0014] Multiple cabinets, there are multiple of them, and the multiple cabinets are arranged in the X-axis direction. Each cabinet is provided with a lock device and a door that can be opened by the key. The unlocking assembly can move to the position corresponding to the lock device of each cabinet, and by rotating the key, an unlocking state is formed. The door has an elastic structure, and the door automatically pops open to form an open state in the unlocking state;

[0015] A control system controls the X-axis moving device and the unlocking assembly. The specific steps are as follows:

[0016] S1. Control the X-axis moving device to move so that the unlocking assembly moves to the position corresponding to the cabinet that needs to be opened;

[0017] S2. Control the electric device of the unlocking assembly to rotate the key of the unlocking assembly to perform the door opening operation.

[0018] Furthermore, the automatic door opening device for multiple cabinets further includes a door state detection device. The door state detection device contains a position sensor. The position sensor is fixed on the X-axis moving device and moves with the X-axis moving device. The position sensor is used to detect the open or closed state of the door of the cabinet. The control system can process the state. The processing method is to continue to execute the following steps after performing steps S1 - S2 of claim 1:

[0019] S3. After the delay, check the status of the door of the cabinet. If it is open, it is determined that the door opening operation is successful. Otherwise, it is determined that the door opening operation fails. If the door opening operation is successful, proceed to step S4.

[0020] S4. The state of the door of the door cabinet is cyclically checked over a period of time. If the state is closed, it is determined that the door of the door cabinet has been closed again; otherwise, it is determined that the door is still open.

[0021] Furthermore, the X-axis moving device includes a first motor, a driving wheel, a driven wheel and a belt, the driving wheel is fixed on the output shaft of the first motor, the driven wheel is spaced apart from the driving wheel, and the belt is sleeved on the driving wheel and the driven wheel.

[0022] Furthermore, the electric device of the unlocking assembly that can rotate the key is a second motor, the key is a cam, the cam is fixed on the output shaft of the second motor, and the second motor is fixed on the belt.

[0023] Furthermore, the locking device includes a latch, a rotating shaft, a lock tongue and a frame, the lock tongue is fixed one by one on the door of each door cabinet, the frame is provided with a through hole, the lock tongue is inserted into the through hole, and forms a slot with the wall of the frame; one end of the latch is mounted on the frame through a rotating shaft and can rotate around the rotating shaft; the other end of the latch can be naturally inserted into the slot under the action of gravity to form a locked state; the cam of the unlocking assembly can rotate with the second motor and push open the latch, so that the latch is disengaged from the slot to form an unlocked state.

[0024] Furthermore, the position sensor is a proximity sensor for detecting metal targets, and the door of the door cabinet has a metal part. The different states of opening or closing the door correspond to the different states of the metal part being away from or close to the sensing area of the proximity sensor, thereby judging the open or closed state of the door of the door cabinet.

[0025] Furthermore, the position sensor is a reflective photoelectric sensor, and the door of the door cabinet has a reflective component. The different states of the door being open or closed correspond to the different states of the reflective component being away from or close to the sensing area of the reflective photoelectric sensor, thereby judging the open or closed state of the door of the door cabinet.

[0026] Furthermore, the position sensor is a through-beam photoelectric sensor, and the door of the door cabinet has a shading component. The different states of the door being opened or closed correspond to the different states of the shading component not blocking or blocking the light of the through-beam photoelectric sensor, thereby judging the open or closed state of the door of the door cabinet.

[0027] Furthermore, the position sensor is a tactile switch, and the door of the cabinet has a protruding structure. Different states of the door being opened or closed respectively correspond to different states of the protruding structure not pressing or pressing the button of the tactile switch, thereby determining the opened or closed state of the door of the cabinet.

[0028] An overall device of the present invention is provided with upper and lower multi-layer cabinets, and the automatic door opening devices of the plurality of cabinets are installed on each layer. The overall device is an overall device using the automatic door opening devices of the above-mentioned plurality of cabinets, and its control system can be appropriately integrated and optimized without affecting the effect of the present invention.

[0029] The beneficial effects of the present invention are as follows:

[0030] In the present invention, the unlocking component and the door state detection device are fixed on the X-axis moving device. As the X-axis moving device moves to a suitable position, it can cooperate with the devices on each cabinet to complete the automatic door opening of multiple cabinets, and can detect the opened or closed state of multiple doors. The structure of each cabinet is relatively simple, and the cabinet does not contain electronic and electrical components, and there are no wires to be connected. The present invention is particularly suitable for occasions where multiple cabinets need to be controlled, which can greatly reduce the installation complexity, save labor and material costs, and improve the product reliability.

[0045] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only the preferred embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0046] Embodiment 1

[0047] Please refer to the attached Figure 3 , an automatic door opening device for multiple cabinets, including an X-axis moving device 1, an unlocking component 2, a cabinet 3, and a control system 4. Preferably, this embodiment further includes a door state detection device 5.

[0048] The X-axis moving device 1 is used to provide movement in the X-axis direction, and there are various ways to achieve it. For example, the way of using a lead screw and a sleeve is adopted. The sleeve is threadedly connected to the lead screw, the lead screw is fixed to the motor, and the motor drives the lead screw to rotate, thereby driving the screw rod to move in the X-axis direction. Please refer to the attached Figure 4 , the X-axis moving device 1 in this embodiment includes a first motor 10, a driving wheel 11, a driven wheel 12, and a belt 13. The driving wheel 11 is fixed on the output shaft of the first motor 10, the driven wheel 12 is arranged at an interval from the driving wheel 11, and the belt 13 is sleeved on the driving wheel 11 and the driven wheel 12. Using belt transmission, it is easy to adjust the required length, and the movement in the X-axis direction is relatively stable.

[0049] The X-axis herein describes a direction. Those skilled in the art can also use the Y-axis or other terms to describe a direction, such as the left-right direction or the left-right horizontal direction, which should not affect the protection scope of the present invention.

[0050] When the X-axis moving device works, for example, when receiving a corresponding electrical signal, the first motor starts, drives the driving wheel to rotate, and thus drives the belt to move along the X-axis.

[0051] In this embodiment, the first motor 10 is a stepper motor and is controlled in an open-loop manner through a control system. The specific method is as follows: the control system controls the rotation direction and the number of electrical pulses of the first motor, thereby controlling the rotation direction and angle of the first motor each time, and thus controlling the moving distance of the X-axis moving device on the X-axis each time, and further controlling the position of the X-axis moving device on the X-axis. Without creative labor, those of ordinary skill in the art can also select other motors, such as using a servo motor including an encoder or using an ordinary DC or AC motor combined with other position sensors to perform closed-loop control on the X-axis moving device.

[0052] The unlocking assembly 2, which includes a key and an electric device for rotating the key, is fixed on the X-axis moving device and moves with the X-axis moving device. There are various structures that the unlocking assembly 2 can achieve. Please refer to the appendix Figure 5 In this embodiment, the unlocking assembly includes a second motor 20 and a cam 21. The cam 21 is fixed on the output shaft 200 of the second motor 20. The second motor 20 is fixed on the belt 13 of the X-axis moving device 1 through a bracket 6. The cam is equivalent to the key in the unlocking assembly 2, and the second motor is equivalent to the electric device that can rotate the key in the unlocking assembly 2. As an alternative embodiment, for example, the cam can be replaced with a flat square block to achieve the same effect. The cam is a relatively mature formed part, and the cam is preferably used in this embodiment. The shape of the bracket 6 is not limited, so that various different embodiments can be formed as long as it can carry and fix the corresponding components. There are also various ways to fix the bracket on the belt, such as direct bonding, screw fixation, or indirect fixation through a clamping device. In this embodiment, the screw fixation method is used (not shown in the figure).

[0053] In this embodiment, the second motor 20 is an 180-degree servo motor, which is convenient for controlling the position of the cam 21. Without creative labor, those of ordinary skill in the art can also use other motors to achieve the same effect, such as using other servo motors including encoders or using ordinary DC or AC motors combined with other position sensors to perform closed-loop control on the cam. Please refer to the appendix Figure 6, the present invention has a plurality of door cabinets 3 arranged in the X-axis direction, and the number thereof is generally 10 to 50. The more the number of door cabinets, the more remarkable the cost-saving effect of the present invention. However, if the number is too large, due to the large volume, the stroke of the X-axis moving device is too large, the moving time-consuming increases, and the user experience is affected. In this embodiment, the number of door cabinets is 20.

[0054] Refer to the appendix Figure 7 , the door cabinet 3 of this embodiment includes a locking device 30 and a door 31. The door 31 is installed on the housing of the device through a door shaft 310 and can rotate around the door shaft 310 to realize the opening and closing operations of the door. There are various structures that the locking device 30 can achieve. The locking device 30 of this embodiment includes a bolt 303, a locking tongue 302, a rotating shaft 304 and a frame 301. The locking tongues 302 are fixedly arranged on the doors 31 of each door cabinet 3 in a one-to-one correspondence.

[0055] Appendix Figure 8 Illustrates the state where the unlocking assembly 2 is away from the current door cabinet 3, the door 31 of the door cabinet 3 is closed, and the locking device 30 is locked. The frame 301 of the door cabinet 3 is composed of sheet metals in various directions required to enclose the storage space of the door cabinet. It is provided with an extension 314 extending from the top plate, and a through hole 316 is provided on the extension 314. When the door is in the closed state, the locking tongue 302 can be inserted into the through hole 316 and form a slot 317 with the plate wall of the frame 301. There is a hem 318 at the top of the bolt 303 (the hem is illustrated in the appendix Figure 10 ), one end of the bolt 303 is installed on the frame 301 through a rotating shaft 304 and can rotate around the rotating shaft 304. The other end of the bolt 303 can be inserted into the slot 317 under the action of natural gravity to block the locking tongue 302 from leaving the through hole 316, thereby forming a locked state.

[0056] The shape of the locking tongue 302 is not limited. It can be in the shape of an arrow "→" formed by a combination of a cylinder and a cone, or in the shape of a combination of a cylinder and a frustum of a cone, or in the shape of a combination of two cylinders with different outer diameters. As long as a slot can be formed with the wall of the frame after insertion. In this embodiment, the shape of the locking tongue 302 is a combination of a cylinder and a frustum of a cone.

[0057] Before unlocking, the unlocking assembly 2 moves with the X-axis moving device and stops at a specific position. Please refer to the appendix Figure 9 , since the output shaft 200 of the second motor 20 and the cam 21 serving as the key are in the initial positions and do not exert external forces on the locking device 30 and the door 31, similar to the situation in the appendix Figure 8 , the locking device 30 is still in the locked state and the door 31 will not open.

[0058] When unlocking, please refer to the appendix Figure 10, the output shaft 200 of the second motor 20 of the unlocking assembly 2 drives the cam 21 acting as a key to rotate by an angle. The cam abuts against the flange 318 of the bolt 303. As the cam continues to rotate, the bolt 303 is lifted and leaves the slot 317. The lock tongue 302 can leave the through hole, and the lock device 30 forms an unlocked state. At the same time, since the door 31 is provided with an elastic structure, when the lock device 30 is in the unlocked state, the door 31 automatically springs open to form an open door state, thus achieving the effect of automatically opening the door of the device in this embodiment.

[0059] Please refer to the appendix Figure 11 , the door 31 of this embodiment is provided with a spring 311. Due to the elastic force of the spring, as long as the lock device 30 is in the unlocked state and the lock tongue 302 is no longer restricted by the bolt 303, the door 31 rotates around the door shaft 310 to form an open door state.

[0060] After the door is opened, the second motor 20 continues to drive the cam 21 acting as a key back to the initial position shown in the appendix Figure 9 , so as not to affect the manual closing and locking operation of the personnel after the automatic door opening, and at the same time to prepare for the unlocking assembly 2 to move with the X-axis moving device and the next unlocking.

[0061] This embodiment also has a door state detection device 5, which includes a position sensor 50 and is fixed on the X-axis moving device and moves with the X-axis moving device for detecting the open or closed state of the door of the cabinet.

[0062] The position sensor can be a proximity sensor for detecting a metal target, and at the same time, the door of the cabinet is provided with a metal component; according to the specific structure, it can be set that when the door is opened, the metal component moves away from the sensing area of the proximity sensor, and when the door is closed, the metal component moves closer to the sensing area of the proximity sensor; it can also be set through a different structure that when the door is opened, the metal component moves closer to the sensing area of the proximity sensor, and when the door is closed, the metal component moves away from the sensing area of the proximity sensor.

[0063] The position sensor can also be a reflective photoelectric sensor, and at the same time, the door of the cabinet is provided with a reflective component; according to the specific structure, it can be set that when the door is opened, the reflective component moves away from the sensing area of the reflective photoelectric sensor, and when the door is closed, the reflective component moves closer to the sensing area of the reflective photoelectric sensor; it can also be set through a different structure that when the door is opened, the reflective component moves closer to the sensing area of the reflective photoelectric sensor, and when the door is closed, the reflective component moves away from the sensing area of the reflective photoelectric sensor.

[0064] The position sensor may also be an opposed photoelectric sensor, and a light-shielding component is provided on the door of the cabinet. According to the specific structure, it can be set that when the door is opened, the light-shielding component does not block the light of the opposed photoelectric sensor, and when the door is closed, the light-shielding component blocks the light of the opposed photoelectric sensor; alternatively, through a different structure, it can be set that when the door is opened, the light-shielding component blocks the light of the opposed photoelectric sensor, and when the door is closed, the light-shielding component does not block the light of the opposed photoelectric sensor.

[0065] The position sensor may also be a tactile switch, and a protruding structure is provided on the door of the cabinet. According to the specific structure, it can be set that when the door is opened, the protruding structure does not press the button of the tactile switch, and when the door is closed, the protruding structure presses the button of the tactile switch; alternatively, through a different structure, it can be set that when the door is opened, the protruding structure presses the button of the tactile switch, and when the door is closed, the protruding structure does not press the button of the tactile switch.

[0066] By the above method, the open or closed state of the door can be converted into the electrical signal output of the door state detection device, which is convenient for the control system to make judgments and process. Those of ordinary skill in the art can implement the specific structure corresponding to the above method without creative efforts.

[0067] Refer to the appendix Figure 12 , in this embodiment, the position sensor 50 of the door state detection device is a proximity sensor for detecting a metal target, and its effective monitoring range is 0 to 4 mm. It is fixed on the belt 13 of the X-axis moving device through the bracket 6. At the same time, a metal component 51 is provided on the door of the cabinet, and the metal component 51 is a steel screw used to fix the lock tongue 302 on the door 31. When the door 31 is closed, the position sensor 50 detects the approach of the metal component 51 and outputs a high level. When the door is opened, the metal component 51 moves away from the sensing area of the position sensor 50, and the position sensor 50 outputs a low level.

[0068] Refer to the appendix Figure 13 , in this embodiment, the position sensor 50 and the second motor 20 are fixed on the same bracket 6, and their relative positions are determined by the specific structural parameters of the cabinet 3. Of course, they can also be fixed separately, and the relative positions of the two also need to meet the requirements, which will not be elaborated here.

[0069] The control system 4 in this embodiment includes a microcontroller and an industrial touch all-in-one computer. The microcontroller and the industrial touch all-in-one computer are connected through an RS232 interface and can communicate with each other. The industrial touch all-in-one computer mainly realizes functions of networking and human-computer interaction. The microcontroller directly controls the X-axis moving device 1 and the unlocking component 2, and reads and processes the signals of the door state detection device 5. The software method is as follows:

[0070] S1. Control the X-axis moving device to move so that the unlocking component moves to a position corresponding to the cabinet door to be opened. Specifically, the industrial touch all-in-one computer receives an opening instruction for a certain cabinet door and sends it to the microcontroller. The opening instruction comes from a legal operation of a person on the local machine or a legal control command of a remote device on the network. After receiving the opening instruction, the microcontroller calculates according to the current position and the target position of the X-axis moving device, combined with the specific parameters of the transmission structure member of the X-axis moving device and the first motor 10, determines the rotation direction and angle of the first motor, converts it into a corresponding control signal to control the first motor 10, so that the X-axis moving device moves to the target position, thereby making the unlocking component 2 and the door state detection device 5 move to the corresponding positions.

[0071] S2. Control the electric device of the unlocking component to rotate the key of the unlocking component to perform an opening operation. Specifically, the microcontroller controls the second motor 20 of the unlocking component 2 to rotate a certain angle, and after maintaining for a certain time, returns to the initial position. During the rotation process, the cam 21 of the unlocking component 2 acts as a key and rotates accordingly, thereby completing the unlocking operation. In this embodiment, the time required to complete this step is less than 1 second.

[0072] S3. After a delay, check the state of the door of the cabinet. If it is open, determine that the current opening operation is successful; otherwise, determine that the current opening operation fails. Specifically, after the microcontroller unlocks, it delays for 0.5 seconds and then reads the output level of the position sensor 50 to check the state of the door of the cabinet. If it is determined that the door is open, it is determined that the current opening operation is successful, and step S4 is continued; otherwise, it is determined that the current opening operation fails, and the failure information is sent to the industrial touch all-in-one computer, and the industrial touch all-in-one computer prompts the opening failure by means of sound, text, image, etc.

[0073] S4. Continuously check the state of the door of the cabinet within a certain period of time. If it is closed, determine that the door of the cabinet has been closed again; otherwise, determine that the door is still in the open state. Specifically, within two minutes, the microcontroller continuously reads the output level of the position sensor 50 to check the state of the door of the cabinet and sends this state to the industrial touch all-in-one computer. If the door is in the closed state, the industrial touch all-in-one computer prompts the end of a complete operation by means of sound, text, image, etc.; otherwise, the industrial touch all-in-one computer reminds the user to close the door manually by means of sound, text, image, etc.

[0074] There are various specific implementation manners of the control system, which will not be elaborated herein.

[0075] In the present invention, the unlocking component 2 and the door state detection device 5 are installed on the X-axis moving device 1. Referring to the appendix Figure 13 , only 1 second motor 20 is used to perform automatic door opening operations on multiple door cabinets, and only 1 position sensor 50 is used to detect the open or closed states of multiple doors. And each door cabinet 3 itself only requires some simple pure mechanical structures. In the solution of the background art, the number of electric control locks needs to be the same as the number of door cabinets, and each electric control lock needs to be connected to 4 wires. When the number of door cabinets is relatively large, for example, more than 10, the present invention undoubtedly greatly reduces the installation complexity, saves labor and material costs, and at the same time, the product reliability is also improved.

[0076] Embodiment 2

[0077] The whole device of this embodiment is a book self-service borrowing and returning machine, which needs to control 120 door cabinets. The book self-service borrowing and returning machine of this embodiment is provided with upper and lower multi-layer door cabinets, and each layer is equipped with the automatic door opening device of multiple door cabinets in Embodiment 1.

[0078] Specifically, in this embodiment, the door cabinets are divided into 6 layers, with 20 door cabinets in each layer. Similar to Embodiment 1, each layer is provided with 1 set of X-axis moving device, 1 set of unlocking component, 1 set of door state detection device, and each layer also has 1 microcontroller. A total of 6 microcontrollers and 1 industrial touch all-in-one machine form the control system of this embodiment.

[0079] In the control system of this embodiment, the industrial touch all-in-one machine and the 6 microcontrollers are connected through the RS485 bus. The industrial touch all-in-one machine serves as the main node and communicates with the microcontrollers of each layer respectively. There is no need for communication between microcontrollers.

[0080] The software method of the control system in this embodiment is similar to that in Embodiment 1. The difference is that the industrial touch all-in-one machine needs to select the corresponding microcontroller for communication according to the layer where the door cabinet to be opened is located. For the specific steps, refer to Embodiment 1 and will not be elaborated herein.

[0081] Embodiment 3

[0082] The whole device of this embodiment is an express delivery locker. The express delivery locker of this embodiment is provided with upper and lower multi-layer door cabinets, and each layer is equipped with the automatic door opening device of multiple door cabinets in Embodiment 1.

[0083] The difference from Embodiment 1 is that there is no door state detection device in Embodiment 1 in this embodiment. Under normal circumstances, it does not affect the use, but in case of equipment failure, manual repair is required. For the specific details, refer to the adaptive changes in Embodiment 1 and will not be elaborated herein.

[0084] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the present invention, and they are not intended to limit the protection scope of the present invention. Any equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included within the protection scope of the present invention.
