Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is further described in detail below with reference to fig. 1-5 and the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The first embodiment is as follows:
the embodiment of the application discloses a locking control system for movable columns of a compact shelf. Referring to fig. 1 and 2, the locking control system of the movable column of the compact shelf comprises a driving device 1, a locking mechanism 2 and a control module 3. The control module 3 is used for receiving a locking signal and an unlocking signal so as to control the driving device 1 to drive the locking mechanism 2 to be close to or far away from the chain wheel 4 on the compact shelf. When the locking mechanism 2 is abutted against at least one surface of a tooth gap formed by two adjacent gear teeth on the chain wheel 4, the chain wheel 4 is locked, so that a transmission system of the compact shelf connected with the chain wheel 4 cannot run, and the stability of the compact shelf during edge column locking is improved.
Specifically, a mounting frame is fixedly arranged on the compact shelf at a position close to the chain wheel 4. The mounting frame is made by bending a rectangular plate. Specifically, two ends of the rectangular plate are bent 90 degrees to the same surface of the rectangular plate to form two connecting plates 6. The mounting frame is fixed on the compact shelf by a fixed connection mode such as bolt connection, and the opening of the mounting frame faces away from the compact shelf, wherein the connecting plate 6 close to the chain wheel 4 faces the chain wheel 4.
Referring to fig. 1, the driving device 1 includes a fixed end 11 and a telescopic end 12, wherein the fixed end 11 is fixedly disposed on the connecting plate 6 far from the sprocket 4 by bolting. Meanwhile, the mounting frame is also fixedly provided with a limiting frame 7 so as to limit the position of the telescopic end 12. All offer the circular through-hole that supplies flexible end 12 to pass on the face towards uncovered one side on the perpendicular to mounting bracket on spacing 7 for flexible end 12 can remove, in order to be close to or keep away from sprocket 4.
It will be appreciated that the length of the drive unit 1 is less than the length of the mounting frame, i.e. there is a gap between the end of the telescopic end 12 adjacent the sprocket wheel 4 and the web 6 adjacent the sprocket wheel 4 when the drive unit 1 is secured to the mounting frame. In the present application, the drive means 1 is preferably an electric push rod.
The locking mechanism 2 is fixedly arranged at the end part of the telescopic end 12 close to the chain wheel 4, passes through a limiting through hole arranged at a corresponding position on the connecting plate 6 close to the chain wheel 4, and is used for moving towards the chain wheel 4 under the driving of the driving device 1. Specifically, the locking mechanism 2 is a column, and one bottom surface thereof is fixedly arranged at the end part of the telescopic end 12 close to the chain wheel 4, and the circle center of the bottom surface coincides with the axis of the telescopic end 12. One end of the locking mechanism 2 close to the chain wheel 4 is provided with a tangent plane which is completely matched with the shape of the tooth gap between two adjacent teeth on the chain wheel 4, so that the locking mechanism is abutted against the tooth gap when being inserted between two teeth, and then the chain wheel 4 is locked. Of course, the tangential surface of the locking mechanism 2 at the end closer to the sprocket 4 may have any other shape that can be inserted into the slot, and may abut against at least one surface of the slot.
Referring to fig. 1 and 2, the control module 3 is configured to receive a locking signal and an unlocking signal, and to output a first control signal when receiving the locking signal and a second control signal when receiving the unlocking signal, the first control signal being configured to control the driving device 1 to generate a driving force towards the sprocket 4, and the second control signal being configured to control the driving device 1 to generate a driving force away from the sprocket 4.
Referring to fig. 2 and 3, in particular, the control module 3 includes coils KM1, KM2 of a relay, an isolation unit 31, a driving unit 32, and an output unit 33.
The isolation unit 31 is used for receiving and transmitting the locking signal and the unlocking signal output by the singlechip 8. It should be noted that the locking signal and the unlocking signal mentioned in the embodiment of the present application are composed of the levels output by the two output pins of the single chip microcomputer 8. The lock signal is composed of a low level output from the output pin PB15 and a high level output from the output pin PB3, and is referred to as (0, 1) for convenience of description. And the unlock signal is composed of a high level output from the output pin PB15 and a low level output from the output pin PB3, and is referred to as (1, 0).
The isolation unit 31 includes two optoelectronic isolation devices U1, U2. Since the two optoelectronic isolation devices U1 and U2 are connected in the same connection manner, one of the optoelectronic isolation devices U1 is described as an example.
The input terminal of the optoelectronic isolation device U1 is connected in series to the first power supply 9, and the output terminal thereof is connected in series to the second power supply 10. Specifically, the input anode of the photoelectric isolation device U1 is connected to the first power supply 9, the input cathode is used for receiving a high level signal or a low level signal sent by the single chip microcomputer 8, the output anode is connected to the second power supply 10, and the output cathode is grounded. When the input cathode of the optoelectronic isolation device U1 receives a low level signal, the input terminal of the optoelectronic isolation device U1 is turned on, and the light emitting diode of the optoelectronic isolation device U1 outputs an optical signal. At this time, the phototransistor of the photo isolator device U1 receives the optical signal and turns on, and the output cathode of the photo isolator device U1 outputs a high level signal. On the contrary, when the input cathode of the optoelectronic isolation device U1 receives a high level signal, the input terminal of the optoelectronic isolation device U1 is not conducted, and the light emitting diode of the optoelectronic isolation device U1 does not output an optical signal. At this time, the output terminal of the optoelectronic isolation device U1 is not conductive, i.e. its output cathode outputs a low level signal.
It can be understood that the locking signal sent by the single chip microcomputer 8 is (0, 1), that is, the optoelectronic isolation device U1 connected to the output pin PB15 of the single chip microcomputer 8 outputs a high level signal, and similarly, the optoelectronic isolation device U2 connected to the output pin PB3 of the single chip microcomputer 8 outputs a low level signal. Thus, the lock-up signal output after being isolated by the isolation unit 31 is (1, 0). Similarly, after the unlocking signal sent by the single chip microcomputer 8 is isolated by the isolation unit 31, the output unlocking signal is (0, 1).
The voltage of the first power supply 9 is 5V, and the voltage of the second power supply 10 is 12V.
The driving unit 32 is connected to the output end of the isolation unit 31, and is used for receiving the locking signal and the unlocking signal, and driving the coil KM1 of the relay or the coil KM2 of the relay to be conducted.
Specifically, the driving unit 32 includes two NPN transistors T1, T2. Since the two transistors T1, T2 are connected in the same connection manner, one of the transistors T1 is taken as an example.
The base of the transistor T1 is connected to the output cathode of a photo-isolation device U1, the collector is connected to the second power supply 10, and the emitter is grounded. When the base is low, the transistor T1 is not conductive, i.e., the collector outputs a high signal. Conversely, when the base is at a high level, the transistor T1 is turned on, i.e., the collector outputs a low signal.
Further, the relays in the embodiments of the present application are also provided with two relays, that is, there are two relays of coils KM1 and KM 2. Since the coils KM1 and KM2 of the two relays are connected in the same connection manner, the coil KM1 of one of the relays is described as an example.
One end of a coil KM1 of the relay is connected with the second power supply 10, and the other end is connected with the collector of a triode T1. When the collector is at a low level, the coil KM1 of the relay is in a powered state, whereas when the collector is at a high level, the coil KM1 of the relay is in a powered-off state.
Therefore, it can be known that when the driving unit 32 receives the locking signal (1, 0) output by the isolation unit 31, the collector of the transistor T1 indirectly connected to the output pin PB15 of the single chip microcomputer 8 outputs a low level signal, so that the coil KM1 of the relay connected to the collector is powered. Meanwhile, the collector of the triode T2 indirectly connected with the output pin PB3 of the single chip microcomputer 8 outputs a high level signal, so that the coil KM2 of the relay connected with the collector loses power. Similarly, when the driving unit 32 receives the unlocking signal (0, 1) output by the isolation unit 31, the collector of the transistor T1 indirectly connected to the output pin PB15 of the single chip microcomputer 8 outputs a high-level signal, so that the coil KM1 of the relay connected to the collector is de-energized. Meanwhile, the collector of the triode T2 indirectly connected with the output pin PB3 of the single chip microcomputer 8 outputs a low level signal, so that the coil KM2 of the relay connected with the collector is powered.
In order to facilitate the working state of the locking control system of the present application to be known to the staff, an indicator LED is further provided on a line connecting the collector of each transistor T1, T2 and the second power supply 10. Preferably, the indicator light LED is a light emitting diode. Specifically, the light emitting diode and the fixed resistor are connected in series between the second power source 10 and the collector. Wherein the anode of the light emitting diode is connected to a second power supply 10.
In addition, a clamping diode D1 is connected in parallel to both ends of the fixed resistor and the light emitting diode. The clamping diode D1 has an anode connected to the collector of the transistor T1 and a cathode connected to the second power supply 10.
The output unit 33 includes two identical output sub-units 331, and the two output sub-units 331 are connected in parallel, and one of the output sub-units 331 is taken as an example for description.
The output subunit 331 includes a relay contact KM1-1, and the relay contact KM1-1 includes two fixed terminals and one movable terminal. One of the fixed terminals is connected to the second power source 10, the other fixed terminal is grounded, and the movable terminal is connected to one of the fixed terminals under the control of the coil KM1 of the relay to output a low-level signal or a high-level signal. Specifically, when the coil KM1 of the relay is in a power-on state, the movable terminal is connected to the fixed terminal connected to the second power source 10 to output a high-level signal, whereas when the coil KM1 of the relay is in a power-off state, the movable rod terminal is connected to the fixed terminal grounded to output a low-level signal.
Further, the fixed terminals of the two output sub-units 331 connected to the second power supply 10 are connected to form a common node, and the common node is also connected to the first power supply 9.
From the above description, it can be understood that, when the driving unit 32 receives the locking signal (1, 0) output by the isolation unit 31, the coil KM1 of the relay indirectly connected to the output pin PB15 of the single chip microcomputer 8 is energized, so that the movable terminal of the contact KM1-1 thereof is connected to the fixed terminal connected to the second power supply 10, and a high level signal is output. And a coil KM2 of the relay indirectly connected with an output pin PB3 of the singlechip 8 is powered off, so that the movable end point of a contact KM2-1 is connected with a grounded fixed end point, and a low-level signal is output. At this time, the output terminal of the output unit 33 outputs the first control signal (1, 0). Similarly, when the driving unit 32 receives the unlocking signal (0, 1) output by the isolation unit 31, the coil KM1 of the relay indirectly connected with the output pin PB15 of the single chip microcomputer 8 loses power, so that the movable end point of the contact KM1-1 is connected with the fixed end point of the ground, and a low-level signal is output. A coil KM2 of the relay indirectly connected with an output pin PB3 of the singlechip 8 is electrified, so that a movable end point of a contact KM2-1 is connected with a fixed end point connected with the second power supply 10, and a high-level signal is output. At this time, the output terminal of the output unit 33 outputs the second control signal (0, 1).
Similarly, clamp diodes D3 and D4 are provided on lines connecting the first power supply 9 and the second power supply 10 to the common node. Anodes of the clamping diodes D3, D4 are connected to the first power supply 9 or the second power supply 10.
Drive arrangement 1 connects control module 3 for receive first control signal and second control signal, and be used for producing the drive power towards sprocket 4 when receiving first control signal for flexible end 12 stretches out, and then makes locking mechanical system 2 insert the slot and the butt, takes place to rotate in order to avoid sprocket 4. The drive means 1 are also arranged to generate a driving force directed away from the sprocket wheel 4 upon receiving a second control signal. The telescopic end 12 is retracted, the locking mechanism 2 is not abutted to tooth gaps any more, the chain wheel 4 can rotate at the moment, and the stability of the dense frame edge row during locking is improved.
In addition, the lock control system of the present application includes a communication unit 34, and the communication unit 34 is configured to transmit the lock signal and the unlock signal output by the chip microcomputer 8 to the isolation unit 31. Preferably, the communication unit 34 is a CMOS high-speed transceiver.
The implementation principle of the locking control system of the movable column of the compact shelving in the embodiment of the application is as follows: by providing the driving device 1 and the lock mechanism 2, the lock mechanism 2 can be inserted into the tooth gap of the sprocket 4 under the driving of the driving device 1 and abut against the tooth gap, thereby restricting the movement of the sprocket 4. When the driving device 1 drives the locking mechanism 2 to be far away from the chain wheel 4, the chain wheel 4 can rotate again, and therefore stability in the process of locking the dense frame edge rows is improved.
Example two:
referring to fig. 4 and 5, the present embodiment is different from the first embodiment only in that arc-shaped grooves are symmetrically formed in the side wall of the locking mechanism 2 along the axis thereof, and the two arc-shaped grooves are located on a plane formed in the circumferential direction of the sprocket 4.
Further, the fixed pivot 22 that is provided with on the axis of arc wall, the last rotation of pivot 22 be provided with the stopper 23 of arc wall shape adaptation to the cover is equipped with the torsional spring on the pivot 22, makes stopper 23 pop out in by the arc wall under the restoring force effect of torsional spring. Since the arrangement of the torsion spring is a mature technology in the related art, it will not be described in detail here.
When the driving device 1 drives the locking mechanism 2 to move towards the chain wheel 4, the rotating shaft 22 moves along with the locking mechanism. When the locking mechanism 2 is just inserted into the slot and abuts, the shaft 22 moves to the outside of the link plate 6 near the sprocket 4, and has a certain distance from the link plate 6 near the sprocket 4. At this time, the torsion spring is restored from the compressed state to the original state, i.e., the stopper 23 originally housed in the locking mechanism 2 is ejected from the locking mechanism 2 and abuts against the connecting plate 6 close to the sprocket 4. It is worth to be noted that, a butting groove 61 is further formed in a corresponding position on the connecting plate 6 close to the chain wheel 4, the butting groove 61 is in a sector cylindrical shape, so that when the limiting block 23 is ejected, a part of the limiting block 23 can be just inserted into the butting groove 61 and butted against the same, and when the chain wheel 4 applies acting force to the locking mechanism 2, a supporting force in the opposite direction is provided for the locking mechanism 2, so that the acting force applied to the locking mechanism 2 by the chain wheel 4 is buffered.
It is considered that the torsion spring is gradually compressed as the driving device 1 drives the locking mechanism 2 away from the sprocket 4, so that the stopper 23 is gradually retracted into the locking mechanism 2 as the locking mechanism 2 moves. During the movement of the locking mechanism 2, once the rotating shaft 22 exceeds the plane of the connecting plate 6 close to the chain wheel 4, the stop block 23 still pops out of the locking mechanism 2. For this reason, a sleeve 62 is further fixedly arranged on the surface, away from the sprocket 4, of the connecting plate 6 close to the sprocket 4, the inner diameter of the sleeve 62 is the same as the diameter of the limiting through hole, and the distance between one end, away from the connecting plate 6 close to the sprocket 4, of the sleeve 62 and the limiting frame 7 needs to be larger than the moving distance of the locking mechanism 2.
The foregoing is a preferred embodiment of the present application and is not intended to limit the scope of the application in any way, and any features disclosed in this specification (including the abstract and drawings) may be replaced by alternative features serving equivalent or similar purposes, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.
