Description

Technical Field

[0001] This utility model belongs to the technical field of material transfer equipment, specifically relating to a multi-station telescopic head positioning system. Background Technology

[0002] Telescopic heads are mainly used in multi-station transfer scenarios. For example, they are key equipment for switching processes from port tippers to yard conveyor belts to ship loading conveyor belts.

[0003] Regarding the telescopic head positioning detection method, the most widely used technology at present is the Gray Code Positioning System. The Gray Code Positioning System is laid and tightened along one side of the conveyor belt track. The telescopic head is equipped with an electromagnetic sensor antenna box. After the position coding signal is acquired in real time through electromagnetic coupling, it is encoded and decoded by a scale generator and scale analyzer, and finally transmitted to the central controller. The controller analyzes the position data (accuracy ±2mm) and drives the motor (105) to adjust the telescopic head to the target position, supporting bidirectional operation (forward / backward).

[0004] This method relies excessively on electronic components and complex control systems, making it unsuitable for industrial environments with high dust and humidity.

[0005] Currently, some positioning systems also use proximity switches in conjunction with stop sensors, but these are mostly single point-to-point positioning systems with poor accuracy. Utility Model Content

[0006] The purpose of this invention is to provide a multi-station telescopic head positioning system to solve the above-mentioned problems existing in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-station telescopic head positioning system includes a slide rail, a telescopic head, a conveyor belt, and multiple stations. The slide rail is positioned above each station, and the telescopic head is slidably connected to the slide rail. The conveyor belt is mounted on the telescopic head, which has a discharge port. The discharge end of the conveyor belt is positioned above the discharge port. Multiple directional proximity switches are installed on one side of the slide rail, each corresponding to a station position. A sensing iron frame is installed on the side of the telescopic head near the directional proximity switches. The length of the sensing iron frame is equal to the distance between two adjacent stations, and the front end of the sensing iron frame corresponds to the discharge port position. Multiple position proximity switches are installed on the other side of the slide rail, each corresponding to a station position. A sensing stop is installed on the side of the telescopic head near the position proximity switches, and the sensing stop corresponds to the discharge port position.

[0009] As an alternative or supplement to the aforementioned multi-station telescopic head positioning system, a proximity switch mounting bracket is also included, wherein both the directional proximity switch and the position proximity switch are mounted on the proximity switch mounting bracket.

[0010] As an alternative or supplement to the aforementioned multi-station telescopic head positioning system, the proximity switch mounting bracket is provided with a cross adjustment hole, and both the directional proximity switch and the position proximity switch are fixedly connected to the cross adjustment hole by bolts.

[0011] As an alternative or supplement to the above-mentioned multi-station telescopic head positioning system, the telescopic head is provided with a sensor iron frame mounting bracket, and the sensor iron frame mounting bracket is provided with a cross adjustment hole two. The two ends of the sensor iron frame are fixedly connected to the cross adjustment hole two by bolts.

[0012] As an alternative or supplement to the above-mentioned multi-station telescopic head positioning system, the telescopic head is provided with a sensor stop mounting bracket, and the sensor stop mounting bracket is provided with a cross adjustment hole three, and the sensor stop is fixedly connected to the cross adjustment hole three by bolts.

[0013] As an alternative or supplement to the aforementioned multi-station telescopic head positioning system, each of the aforementioned stations is equipped with 2-3 directional proximity switches or position proximity switches, and the triggering logic is changed to "majority voting".

[0014] Beneficial effects: The multi-station telescopic head positioning system of this utility model determines the moving direction of the telescopic head by sensing between the directional proximity switch and the induction iron frame, and accurately positions the outlet of the telescopic head above the target station by sensing between the position proximity switch and the induction stop.

[0021] Example

[0022] This embodiment provides a multi-station telescopic head positioning system for achieving precise positioning of the discharge port 5 and station 4, thus completing material conveying; please refer to Figure 1 The system includes components such as a slide rail 1, a telescopic head 2, a conveyor belt 3, and multiple workstations 4. The slide rail 1 is positioned above the workstations 4. The telescopic head 2 is slidably connected to the slide rail 1. The conveyor belt 3 is mounted on the telescopic head 2, which has a discharge port 5. The discharge end of the conveyor belt 3 is positioned above the discharge port 5. The workstations 4 are evenly spaced below the slide rail 1. By controlling the movement of the telescopic head 2, the discharge end of the conveyor belt 3 is moved to the target workstation 4, and the material is unloaded through the discharge port 5 on the telescopic head 2.

[0023] In this embodiment, four workstations 4 are used for illustration.

[0024] Four directional proximity switches 6 are installed on one side of the slide rail 1, and each directional proximity switch 6 corresponds to a position of work station 4. An induction iron frame 7 is provided on the side of the telescopic head 2 near the directional proximity switches 6. The length of the induction iron frame 7 is equal to the distance between two adjacent work stations 4, and the front end of the induction iron frame 7 corresponds to the position of the discharge port 5. Four position proximity switches 8 are installed on the other side of the slide rail 1, and each position proximity switch 8 corresponds to a position of work station 4. An induction stop 9 is provided on the side of the telescopic head 2 near the position proximity switches 8, and the induction stop 9 corresponds to the position of the discharge port 5.

[0025] Specifically, four directional proximity switches 6 are installed on one side of slide rail 1, and four position proximity switches 8 are installed on the other side of slide rail 1. For easier explanation, please refer to [reference needed]. Figure 1 The four directional proximity switches 6 on the left side of slide rail 1 are named sequentially from front to back: Directional Proximity Switch 6 (First Direction Proximity Switch 6), Directional Proximity Switch 6 (Second Direction Proximity Switch 6), Directional Proximity Switch 6 (Third Direction Proximity Switch 6), and Directional Proximity Switch 6 (Fourth Direction Proximity Switch 6); the four position proximity switches 8 on the right side of slide rail 1 are named sequentially from front to back: Position Proximity Switch 8 (First Position Proximity Switch 8), Position Proximity Switch 8 (Third Position Proximity Switch 8), and Position Proximity Switch 8 (Fourth Position Proximity Switch 8); the workstations 4 are named sequentially from front to back: Workstation 4 (First Workstation 4), Workstation 4 (Second Workstation 4), and Position Proximity Switch 8 (Fourth Position Proximity Switch 8); Directional Proximity Switch 6 (First Direction Proximity Switch 6) and Position Proximity Switch 8 (First Position Proximity Switch 8) correspond to the positions of Workstation 4 (First Position Proximity Switch 8); Directional Proximity Switch 6 (Second Direction Proximity Switch 8)... Position proximity switch 6 and position proximity switch 8 correspond to the position of station 4; directional proximity switch 6 and position proximity switch 8 correspond to the position of station 4; directional proximity switch 6 and position proximity switch 8 correspond to the position of station 4; the length of the sensing iron frame 7 is equal to the distance between the two adjacent stations 4, and the front end of the sensing iron frame 7 corresponds to the position of the discharge port 5; the sensing iron frame 7 senses the directional proximity switch 6 to confirm the moving direction of the telescopic head 2; the sensing stop 9 corresponds to the position of the discharge port 5, and the sensing stop 9 senses the position proximity switch 8 to complete the precise positioning of the discharge port 5 and the target station 4.

[0026] In use, the multi-station telescopic head positioning system of this utility model first outputs a command through the controller, for example, the command is station 4. When the telescopic head 2 is in another station 4, the triggered proximity switch sends a position signal to the controller to confirm that the telescopic head 2 is not in station 4. The controller then issues a command to drive the telescopic head 2 to move towards station 4. When the sensing iron frame 7 simultaneously triggers the first directional proximity switch 6 and the second directional proximity switch 6, the first directional proximity switch 6 and the second directional proximity switch 6 send a position confirmation signal to the controller, initially confirming that the telescopic head 2 has reached station 4. After the telescopic head 2 reaches station 4, the sensing stop 9 will trigger the first position proximity switch 8, which sends a position confirmation signal to the controller, so that the discharge port 5 is precisely aligned with station 4. By setting the directional proximity switch 6 and the position proximity switch 8, dual position confirmation is achieved, making the positioning more accurate.

[0027] To further improve positioning accuracy, each workstation 4 is equipped with 2-3 directional proximity switches 6 or position proximity switches 8, and the triggering logic is changed to "majority voting". For example, when a workstation 4 is equipped with 3 position proximity switches 8, only when two of the position proximity switches 8 are triggered at the same time does it indicate that the discharge port 5 is completely aligned with the workstation 4.

[0028] In some embodiments, a proximity switch mounting bracket 10 is also included, on which both the directional proximity switch 6 and the position proximity switch 8 are mounted.

[0029] Please see Figure 2 In order to accommodate the deformation of the proximity switch mounting bracket 10, preferably, the proximity switch mounting bracket 10 is provided with a cross adjustment hole 11, and the directional proximity switch 6 and the position proximity switch 8 are both fixedly connected to the cross adjustment hole 11 by bolts; by adjusting the fixed position of the bolts on the cross adjustment hole 11, the proximity switch can be finely adjusted in the horizontal and vertical directions.

[0030] In some embodiments, the telescopic head 2 is provided with a sensor iron frame mounting bracket, the sensor iron frame mounting bracket is provided with a cross adjustment hole 2, and the two ends of the sensor iron frame 7 are fixedly connected to the cross adjustment hole 2 by bolts.

[0031] In some embodiments, the telescopic head 2 is provided with a sensor stop mounting bracket, the sensor stop mounting bracket is provided with a cross adjustment hole three, and the sensor stop 9 is fixedly connected to the cross adjustment hole three by bolts.

[0032] Among them, cross adjustment hole 2 and cross adjustment hole 3 have the same structure as cross adjustment hole 11, and the connection method of induction iron frame 7 and induction stop 9 is the same as the connection method of proximity switch, which will not be described in detail here.

[0033] This utility model discloses a multi-station telescopic head positioning system. The direction of movement of the telescopic head 2 is determined by sensing between the directional proximity switch 6 and the induction iron frame 7. The position of the telescopic head 2's discharge port 5 is accurately positioned above the target station 4 by sensing between the position proximity switch 8 and the induction stop 9. The non-contact sensing design of the proximity switch is more suitable for industrial environments with high dust and high humidity. At the same time, the dual position confirmation makes the positioning more accurate.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
