The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Referring to fig. 1-2 in detail, the present application provides a rotary display signage system comprising:

a fixing mechanism 1;

at least one display sign 2 arranged on the fixing means;

a rotating mechanism 3 configured to drive the display sign 2 to rotate; each display label 2 is connected with the fixing mechanism 1 through at least one rotating mechanism 3;

and the homing mechanism 4 is configured to output a control signal to the rotating mechanism 3 when the display label 2 rotates to a specified position, wherein the control signal is used for controlling the rotating mechanism to stop driving the display label to rotate.

Wherein the rotating mechanism 3 comprises a motor 5, a stator 20 and a rotor 10; the motor 5 is fixed on the stator 20, and the motor 5 drives the rotor 10 to rotate so as to realize the rotary connection between the stator 20 and the rotor 10. The homing mechanism 4 comprises a receiver 21 and at least one dispenser 11, wherein the receiver 21 is arranged on the stator 20, each dispenser 11 limits a designated position, the at least one dispenser 11 is arranged at a circumferential position of the rotor 10, and the receiver generates the control signal when the dispenser 11 passes through a detection area of the receiver 21 during the rotation of the rotor 10.

Fig. 3 and 4 show a structure of one of the rotating mechanisms, wherein 10 is a rotor portion rotatable around the shaft shown in the figure, and 20 is a stator portion fixed. The fitting 11 is fixed on the rotor and can rotate along with the rotor around the shaft, and the switch 21 is fixed on the stator. The fixing means includes, but is not limited to, screws, adapters, etc. for the purpose of fixing the connection.

The working process is as follows: when the rotating platform rotates around the shaft, as shown in fig. 8, it is a random position in the working process, and when the device executes the return-to-zero instruction, the rotor 10 rotates to drive the induction fitting 11 to rotate until the position is above the switch 21, the switch triggers the switch, the switch sends a control signal to the control circuit of the motor, and the control circuit controls the corresponding motor 5 to stop rotating.

The motor of the rotating mechanism is provided with an output shaft (not shown in the figure), in some embodiments, the output shaft of the rotor is directly and fixedly connected, in some embodiments, the output shaft of the motor is provided with a primary gear, and the rotor is provided with a secondary gear matched with the primary gear. The embodiment of the application does not limit the specific transmission mode between the motor and the rotor, and the transmission mode can be applied to the technical scheme of the application.

At least one of the designated positions limited by the at least one dispenser, wherein the at least one designated position includes a zero position, and the zero position is used for indicating a starting point or an ending point of the rotation of the display sign. The return-to-zero position can prevent a plurality of display signs from generating motion interference when rotating, and meanwhile, the return-to-zero position can be used as a starting point or a terminal point of the motor for driving the display signs to rotate, so that the accurate control of the rotation direction and the rotation position of the display signs can be realized.

In the embodiment of the present application, it should be noted that the zeroing position of the homing mechanism at the same position on different display signs is the same or different. In specific setting, the designated positions may further include other reference positions, which is convenient for controlling the advance and the accurate steering of the display sign or setting the rotation limit, and the like.

It should be noted that the zero position corresponds to a zero point in the coordinate system, and all movements of the display sign are relative to the zero position. As the reference of all movements of the display signs, the determination of the zero position not only greatly influences the positioning precision of the movement of the display signs, but also can prevent unknown risks such as screen collision and the like caused by the accumulated deviation of each display sign.

When the display device is arranged, the zero returning positions of the display signs can be set to be the same or different, for example, when the number of the display signs is multiple, the zero returning positions can be planned for saving the arrangement space, the zero returning positions of the display signs are based on the positions where the display signs do not interfere in the movement process, and the arrangement positions and the arrangement of the display signs are set specifically.

Preferably, the receiver is an optoelectronic switch and the dispenser is a shutter.

The photoelectric switch utilizes the shielding or reflection of the detected object to the light beam, and the synchronous circuit is connected with the circuit, thereby detecting the existence of the object. The object is not limited to metal, and all objects that reflect light (or block light) can be detected. The photoelectric switch converts the input current into an optical signal on the transmitter to be emitted, and the receiver detects the target object according to the intensity or the existence of the received light.

Preferably, the receiver is a proximity switch and the dispenser is a metal sheet.

The proximity switch is a position switch which can be operated without mechanical direct contact with a moving part, and when the sensing surface of the object proximity switch reaches an action distance, the switch can be actuated without mechanical contact and any pressure, so that a direct current electric appliance is driven or a control instruction is provided for a computer (PLC) device. When the metal sheet approaches the induction area of the switch, the switch can quickly send out an electric command without contact, and the position and the stroke of the motion mechanism are accurately reflected.

Proximity switch and separation blade are installed respectively on stator and rotor, and when the separation blade when the rotor is rotatory when setting zero position, the separation blade shelters from proximity switch's light, and proximity switch produces the signal of telecommunication and gives control circuit with signal of telecommunication sending, and control circuit makes the motor that corresponds stop rotatory.

In the embodiment of the present application, two rotating mechanisms are disposed on each of the display signs, the rotating mechanisms include a first rotating mechanism 31 and a second rotating mechanism 32, the first rotating mechanism 31 is configured to drive the display sign 2 to rotate around a first direction, and the second rotating mechanism 32 is configured to drive the display sign 2 to rotate around a second direction.

In the coordinate system in the embodiment of the present application, the axis of the pillar is taken as the Z axis, the plane perpendicular to the axis of the pillar is taken as the XY plane, one direction in the plane is taken as the X axis, and the other direction perpendicular to the X axis is taken as the Y axis. In the present application, the first direction is selected as the direction of the Z axis, and the second direction is selected as the direction of the X axis.

In the embodiment of the present application, the rotation of the two display signs when the first direction and the second direction are perpendicular is shown.

The first rotating mechanism comprises a first stator 201 and a first rotor 101, the second rotating mechanism comprises a second stator 202 and a second rotor 102, the first stator 201 is fixedly connected with the fixing mechanism, the second stator 202 is fixedly arranged on the first rotor 101, and the second rotor 102 is fixedly connected with the display label.

As shown in fig. 1 and 2, the zero position state of the two-direction rotation display signage system is shown, and the operation of the two-direction rotation display signage system is that the two screens can rotate 360 degrees around the Z axis in the XY plane, and when the two screens horizontally rotate to the back-to-back state, the two screens can be started to respectively rotate 90 degrees back and forth around the X axis. The rotation angles of the motors are only exemplary, and can be adjusted according to requirements when being implemented.

Fig. 5 and 6 are schematic diagrams of any time node when the system performs a horizontal rotation motion around the Z-axis, where two display signs have a certain angle, the first switch 211 is disposed on the first stator 201, and the first adaptor 111 moves along with the first rotor 101 of the horizontal rotation platform, so that in a non-zero operating state, the first adaptor 111 and the first switch 211 also form a certain angle.

Fig. 7 and 8 are schematic diagrams of any time node when the system performs a rotation motion around the X-axis vertical direction. The two display signs perform vertical rotation around the X-axis direction in the state of rotation around the Z-axis in the horizontal direction of (+90 °) and (-90 °), respectively, taking the above display signs as an example, at this time, the first cooperator 111 and the first switch 211 on the horizontal direction rotation platform also form an angle of 90 °, and the second cooperator 112 and the second switch 212 on the vertical direction rotation platform also form an angle.

After the rotation of the whole system is completed, the two display signs return to the initial positions, but because a mechanical system has a certain error in the execution process, the staying position of the system after the action is finished and the initial position before the action is executed have a certain deviation, and if zero setting is not carried out, the accumulated deviation accumulated day and month can cause unknown risks such as collision of the two display signs and the like.

Therefore, before or after the action is executed, an automatic zero setting instruction is added in the system, the two-axis proximity switches respectively execute identification alignment, when the relative positions of the second matching device 112 and the second switch 212 are consistent with the set state, the second switch 212 generates an electric signal and sends the electric signal to a control circuit of the motor, the control circuit controls the motor on the horizontal rotating platform to stop rotating, the zero setting is finished, and the identification of the first matching device 111 and the first switch 211 is executed in the same way.

The action of executing the return zero position of the rotating motor in the vertical direction is firstly identified, and then the return zero position of the rotating motor in the horizontal direction is executed, so that the following risks are prevented: i.e. the risk of collision when performing a horizontal rotation when there is a certain deviation of the two display signs in the vertical direction resulting in a non-parallel state. It should be noted that, although the embodiment of the present application is expressed as performing homing on the motor on the rotating platform in the vertical direction first, and then performing homing on the motor of the rotating platform horizontally placed, this is merely used to indicate the order of homing, in other embodiments, in order to prevent interference, adjustment may be performed according to the specific position of the display sign, and the present application does not limit the order of homing of each display sign.

Fig. 9 shows a two-directional rotation mechanism assembly of a single display sign, wherein V is a homing mechanism in a vertical rotation direction and VI is a homing mechanism in a horizontal rotation direction. The two rotary platforms respectively control the vertical rotation and the horizontal rotation of a display sign, and the two have no difference in structural principle.
