[0016] In the present invention, unless otherwise specified and limited, the terms "assembly", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can also be a mechanical connection; it can be directly connected, or it can be connected through an intermediate medium, or the two elements can be internally connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0018] like Figure 1 to Figure 2 As shown, the utility model proposes a conveyor line stopper state detection device, including a stopper module, a sensor mounting bracket 2, a sensor assembly, a sensor detection frame 3, a sensor detection point block and a detection system control end, wherein:

[0019] The stopper module performs a stopping or releasing operation under the control of the detection system control end; the stopper module includes a stopper mounting frame 11, a stopper body 12, a stopper telescopic tongue 13, a stopper up and down moving component and an air circuit driving structure, one end of the stopper body 12 is rotatably fixed on the stopper mounting frame 11, and the other end is provided with a stopper telescopic tongue 13; the detection system control end is controlled and connected to the air circuit driving structure, and the stopper module can realize the lifting and retracting functions through the air circuit driving structure, that is, the stopper up and down moving component drives the stopper body 12 to rotate up and down under the control of the air circuit driving structure, drives the stopper telescopic tongue 13 to move up and down, realizes the switching of the stopper body 12 between rising and falling, and is used for the limit pallet system.

[0020] The sensor assembly includes at least three sensors. Sensors are respectively provided at different positions of the sensor mounting bracket 2. A sensor detection point block is provided on the sensor detection frame 3. Since the sensor detection frame 3 is connected to the stopper body 12, the sensor detection frame 3 moves up and down with the movement of the stopper body 12, driving the sensor detection point blocks to be respectively connected to the sensor touch controls at different positions, and the detection system control end is connected to the signals of each sensor.

[0021] Furthermore, the air circuit driving structure includes a cylinder, an air channel and an interface.

[0022] Furthermore, if Figure 1 to Figure 2 As shown, the sensor assembly includes a front lower detection sensor 21, a side lower detection sensor 22 and a side upper detection sensor 23, and the sensor detection point block includes a lower detection fixing pin 31 and an upper detection fixing pin 32. The lower detection fixing pin 31 cooperates to trigger the start of the side lower detection sensor 22, and the upper detection fixing pin 32 cooperates to trigger the start of the side upper detection sensor 23; the front lower detection sensor 21 is used to detect the state of the pallet system, the side lower detection sensor 22 is used to determine whether the stopper module is in the stop state, and the side upper detection sensor 23 is used to determine whether the stopper module is in the release state. With the up and down movement of the sensor detection frame 3, the movement of the linkage sensor detection point block triggers the start and shut down of each installed sensor, and each sensor is fed back to the entire detection system control end to confirm whether to proceed to the next step to ensure the existing accuracy.

[0023] like Figure 3 to Figure 4 As shown, when the stopper module is in the stopping state, the stopper retractable tongue 13 cooperates with the stopper body 12 to be in the rising position, and the pallet system is stopped. The sensor detection frame 3 is in the lower position along with the operation of the stopper body 12, so that the lower detection fixing pin 31 triggers the side lower detection sensor 22 to start, and the sensor detection frame 3 triggers the front lower detection sensor 21 to start through the front detection fixing pin, and the side upper detection sensor 23 is in the closed state.

[0024] like Figures 5 and 6 As shown, when the stopper module is in the release state, the stopper retractable tongue 13 cooperates with the stopper body 12 to be in the lowered position, and the pallet system is released. The sensor detection frame 3 is in the upper position with the operation of the stopper body 12, so that the upper detection fixing pin 32 triggers the side upper detection sensor 23 to start, and the front lower detection sensor 21 and the side upper detection sensor 23 are in the off state.

[0025] The specific operation is as follows: the practical personnel can control the main conveying line section to convey the pallet system to the conveying line stopper state detection device of the utility model, block the pallet system through the stopper module, and move it to the detection position of the sensor assembly. At this time, the front lower detection sensor 21 passes the detection and transmits the arrival signal to the detection system control end so as to issue the next operation command; at this time, the detection system control end sends a signal to the stopper module to issue a command to release the pallet system, that is, the stopper body 12 is controlled to move up and down through the air path drive structure, driving the stopper telescopic tongue 13 to descend, so as to release the pallet system, and the sensor detection frame 3 and the sensor detection point block above are driven to move up and down through the lifting movement of the stopper body 12, so that the sensor detection point block moves to the position of triggering the upper sensor, that is, the upper detection fixing pin 32 triggers the side upper detection sensor 23, and transmits the signal to the detection system control end, so as to clearly inform the detection system control end that the release action is completed smoothly and accurately.

[0026] After the pallet system passes, a signal is sent again through the detection system control end to send a command to the stopper module to restore to the original position, that is, the air circuit drive structure controls the stopper body 12 to move up and down, driving the stopper telescopic tongue 13 to rise, so as to stop the pallet system, and the lifting movement of the stopper body 12 drives the sensor detection frame 3 and the sensor detection point block thereon to move up and down, so that the sensor detection point block moves to the position that triggers the lower sensor, that is, the lower detection fixing pin 31 triggers the side lower detection sensor 22, and transmits the signal to the detection system control end, so as to clearly inform the detection system control end that the reset stop action is completed smoothly and accurately.

[0027] In summary, the release operation was completed perfectly. This cycle is repeated again and again.

[0028] In this embodiment, the sensor detection after the movement of the stopper module is fed back to the detection system control end. Its main purpose is to accurately determine whether the stopper module has returned to the working position and provide an accurate feedback signal for its status. It provides more accurate signal monitoring for high-precision control of whether to release the next pallet, effectively ensuring the accuracy of the conveyor track transmission and achieving high-precision effects.

[0029] At the same time, the multiple sensors used in the sensor assembly are mature and stable sensors, which are installed at various positions of the sensor mounting bracket 2, and can accurately provide whether the stopper has accurately reached the upper or lower stroke during work. After considering the installation space and other concerns, spare sensor installation points are opened in different directions, such as Figure 3 As shown, a vacant installation slot is provided on the right side of the sensor installation bracket 2 to avoid the situation where the sensor cannot be installed when space is limited.

[0030] In addition, the sensor detection point blocks are assembled and designed using conventional standard parts on the market. Subsequent replacement or direct replacement of each sensor detection point block is sufficient, which can greatly save the time for subsequent upgrades.

[0031] In summary, in this embodiment, the proposed conveyor line stop state detection device can make the operation of the stopper more precise and accurate. Through the feedback of sensors at different positions, the operating state of the stopper can be accurately determined. It is suitable for occasions that require high precision during the operation of the stopper. It also simplifies the difficulty of on-site installation. Since standard mounting parts on the market are used, interchangeability is better. At the same time, the main body volume of the conveyor line stop state detection device is smaller than the pallet position, and does not affect the adjacent workstation space, meeting the application requirements of occasions with space restrictions.

[0032] The above are only preferred embodiments of the present invention and do not limit the present invention in any way. Any technician in the relevant technical field, without departing from the scope of the technical solution of the present invention, may make any equivalent replacement or modification to the technical solution and technical content disclosed in the present invention, which shall be deemed as the content of the technical solution of the present invention and still fall within the protection scope of the present invention.
