[0055] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0056] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0057] Reference Figures 1 to 4 The first embodiment of this application proposes a blocking device for stopping the transport of materials. The blocking device for stopping the transport of materials includes: a lifting drive assembly 10, a lifting slide 20, and a probe assembly 30.

[0058] The lifting drive assembly 10 is used for fixed connection to the external frame;

[0059] The lifting carriage 20 is fixed to the drive end of the lifting drive assembly 10;

[0060] The probe assembly 30 includes a probe component 31 and a proximity switch 32; the probe component 31 is elastically telescopically mounted in the middle and fixed through the lifting slide 20, and one end of the probe component 31 is used to contact and sense the material; the proximity switch 32 is fixed to the lifting slide 20 and is inductively connected to the other end of the probe component 31.

[0061] In this embodiment, when the blocking device for stopping the transported material is in operation, the driving end of the lifting drive assembly 10 extends and drives the lifting slide 20 to rise to a specified height. Under the drive of the lifting slide 20, the probe assembly 30 also rises to a specified height, which is the same height as the material. When the material is transported to the vicinity of the probe component 31, the material contacts one end of the probe component 31, and the probe component 31 is pushed and retracts into the lifting slide 20. Then, the proximity switch 32 senses the other end of the probe component 31, and finally controls the material to stop moving according to the sensing information of the proximity switch 32. At this time, the material is in place and is stopped.

[0062] When the blocking device for stopping the transported material is in a non-working state, the lifting drive assembly 10 is in a retracted state, the drive end of the lifting drive assembly 10 is in the lowest position, the probe component 31 is in an extended state, one end of the probe component 31 extends through and out of the lifting slide 20, at this time the proximity switch 32 cannot sense the other end of the probe component 31, so that the material transport mechanism works normally and the material can pass smoothly from above the probe assembly 30.

[0063] Therefore, by combining the lifting drive assembly 10 with the lifting carriage 20, the lifting height of the probe assembly 30 is controlled to switch between a mode at the same height as the material and a mode at a different height from the material. The probe component 31 is used to determine whether the material has been transported to the stop position for subsequent stoppage, and the stoppage status of the probe component 31 is sensed by the proximity switch 32.

[0064] In summary, the blocking device for stopping transported materials enables on-demand material stopping, while reducing structural complexity and manufacturing costs.

[0065] Specifically, the material is a product or a pallet for a product. The blocking device for stopping the transport of the material also includes a processor, which receives sensing information from the proximity switch 32 and then controls the transport mechanism of the material to shut down based on the received information.

[0066] Reference Figures 1 to 4 The probe component 31 includes: a probe bracket 311, a probe bearing 312, a probe guide rod 313, a probe spring 314, a probe body 315, and a probe baffle 316;

[0067] The probe bracket 311 is fixed to the side plate of the lifting slide 20;

[0068] The probe bearing 312 is fixed through and fixed to the probe bracket 311;

[0069] The probe guide rod 313 is slidably inserted through the probe bearing 312;

[0070] One end of the probe spring 314 is fixed to the probe bearing 312;

[0071] The probe body 315 is fixed to one end of the probe guide rod 313 and fixedly connected to the other end of the probe spring 314, as well as the side plate that can slide through the lifting slide 20;

[0072] The probe baffle 316 is fixed to the other end of the probe guide rod 313.

[0073] In this embodiment, the probe bracket 311 is used to install and fix the probe component 31. The probe bearing 312 is used to limit the sliding direction of the probe guide rod 313 and prevent the sliding operation of the probe guide rod 313 from causing wear to the probe bracket 311. Moreover, the probe bearing 312 is fixed to the probe bracket 311 and serves as a telescopic fixed point relative to the probe spring 314. Using the probe spring 314, after the probe body 315 loses its thrust, the telescopic force of the probe spring 314 after being released indirectly drives the probe guide rod 313 to slide within the probe bearing 312 to reset. The probe body 315 contacts the material to be intercepted and serves as a telescopic movable point relative to the probe spring 314. The probe baffle 316 is used as the sensing reference point of the proximity switch 32. Through the pulling and pushing force of the probe guide rod 313, the proximity switch 32 can obtain whether the probe body 315 has contacted the material to be intercepted, or the degree to which the material to be intercepted has been intercepted.

[0074] When the probe body 315 first contacts the material to be stopped, the thrust exerted on the probe body 315 by the material is minimal, and the sliding distance of the probe guide rod 313 within the probe bearing 312 is shortest; indirectly, the area of ​​the probe baffle 316 sensed by the proximity switch 32 is minimal. When the probe body 315 is completely against the material to be stopped, the thrust exerted on the probe body 315 by the material is maximum, and the sliding distance of the probe guide rod 313 within the probe bearing 312 is maximum; indirectly, the area of ​​the probe baffle 316 sensed by the proximity switch 32 is maximum. When the probe body 315 is about to detach from contact with the material to be stopped, the thrust exerted on the probe body 315 by the material returns to minimum, and the sliding distance of the probe guide rod 313 within the probe bearing 312 also returns to its shortest; indirectly, the area of ​​the probe baffle 316 sensed by the proximity switch 32 is also minimal.

[0075] Reference Figures 1 to 4 The probe assembly 30 also includes a buffer pad 33, which is attached to the probe bracket 311. The probe body 315 slidably passes through the lifting slide 20 and the buffer pad 33.

[0076] In this embodiment, the buffer pad 33 is used to reduce the impact force of the material on the lifting slide 20, so as to prevent the lifting slide 20 from being damaged or displaced by the impact force of the material; and to reduce the impact force of the material on the probe body 315, so as to ensure the thrust when the probe body 315 normally senses and contacts the material, and also to avoid the probe assembly 30 being damaged due to excessive thrust at this time.

[0077] Reference Figures 1 to 4 The probe assembly 30 also includes a sensing bracket 34; the sensing bracket 34 is fixed to the base plate of the lifting slide 20; the proximity switch 32 is fixed to the sensing bracket 34;

[0078] The sensing direction of the proximity switch 32 is perpendicular to the driving direction of the lifting drive assembly 10 and the extension / retraction direction of the probe spring 314.

[0079] In this embodiment, the proximity switch 32 and the lifting slide 20 are fixedly installed by the sensing bracket 34.

[0080] Specifically, the proximity switch 32 is located around the side of the probe baffle 316. This ensures that the sensing direction of the proximity switch 32 is perpendicular to the extension and retraction direction of the probe spring 314. When the probe spring 314 is in an extended or retracted state, the probe guide rod 313 will drive the probe baffle 316 to move in the extension and retraction direction. This allows the proximity switch 32 to easily sense and obtain the displacement change of the probe baffle 316 in the extension and retraction direction, thus enabling the detection of the material's stopping state.

[0081] Reference Figure 1 , Figure 2 and Figure 4 The lifting drive assembly 10 includes: a lifting fixing frame 11, a lifting drive component 12, and a lifting guide component 13;

[0082] The lifting and fixing frame 11 is used to fix and connect the external frame;

[0083] The lifting drive component 12 is fixed to the lifting fixed frame 11, and the driving end of the lifting drive component 12 passes through the lifting fixed frame 11 to connect to the lifting slide 20.

[0084] One end of the lifting guide 13 passes through the lifting fixing frame 11 and is fixed to the lifting slide 20.

[0085] In this embodiment, the lifting fixing frame 11 is used to uniformly install the lifting drive component 12 and the lifting guide component 13. The lifting drive component 12 is used to realize the lifting and lowering movement of the lifting slide 20, which indirectly realizes the lifting and lowering movement of the probe assembly 30, making it convenient to adjust whether the probe assembly 30 is aligned with the material height. The lifting guide component 13 is used to limit the lifting and lowering driving direction of the lifting drive component 12 to improve the smoothness of the lifting and lowering movement.

[0086] In some embodiments, the lifting guide 13 is a linear slide block, the slide rail of the linear slide block is fixed to the lifting fixing frame 11, the slider of the linear slide block is fixedly connected to the lifting slide frame 20, and the driving direction of the lifting drive 12 is parallel to the setting direction of the slide rail of the linear slide block.

[0087] Reference Figure 1 , Figure 2 and Figure 4 The probe bracket 311 includes: a first bracket foot 3111, a bracket extension plate 3112, and a bracket mounting plate 3113;

[0088] The first bracket leg 3111 is fixedly connected to the side plate of the lifting slide 20;

[0089] One end of the bracket extension plate 3112 is fixed to the first bracket leg 3111, and the extension direction of the bracket extension plate 3112 is parallel to the elastic extension direction of the probe spring 314.

[0090] The bracket mounting plate 3113 is fixed to the other end of the bracket extension plate 3112, and the probe bearing 312 is fixed through the bracket mounting plate 3113.

[0091] In this embodiment, the bracket mounting plate 3113 is installed and fixed using the first bracket foot 3111 and the bracket extension plate 3112. The bracket extension plate 3112 is used to limit the distance between the bracket mounting plate 3113 and the carriage side plate 21, and combined with the probe guide rod 313, it limits the extension and retraction direction and degree of the probe spring 314.

[0092] In some embodiments, a bracket extension plate 3112 is fixedly connected to each end of the bracket mounting plate 3113; correspondingly, a first bracket leg 3111 is fixedly connected to each bracket extension plate 3112. This is to improve the structural stability of the probe bracket 311.

[0093] Reference Figure 1 , Figure 2 and Figure 4 The probe bearing 312 includes: a first bearing mounting plate 3121 and a first bearing through cylinder 3122;

[0094] The first bearing mounting plate 3121 is fixed to the bracket mounting plate 3113, and one end of the probe spring 314 is connected and fixed to one side of the first bearing mounting plate 3121.

[0095] The first bearing through-tube 3122 is fixed to the other plate surface of the first bearing mounting plate 3121, the first bearing through-tube 3122 passes through the bracket mounting plate 3113, and the probe guide rod 313 slides through the first bearing mounting plate 3121 and the first bearing through-tube 3122.

[0096] In this embodiment, the first bearing mounting plate 3121 is used to fix the first bearing through cylinder 3122 to the bracket mounting plate 3113. The first bearing mounting plate 3121 and the first bearing through cylinder 3122 are used to achieve a slidable installation of the probe guide rod 313, avoiding wear on the bracket mounting plate 3113 caused by the sliding of the probe guide rod 313.

[0097] Further in this embodiment, the probe baffle 316 and the first bearing mounting plate 3121 are located at both ends of the first bearing through-tube 3122. This limits the maximum elongation of the probe spring 314 by utilizing the lengths of the probe baffle 316 and the first bearing through-tube 3122. The first bearing mounting plate 3121 provides a fixed point for the extension and retraction of the probe spring 314. The slide side plate 21 then limits the maximum contraction of the probe spring 314.

[0098] Reference Figures 1 to 4 The lifting carriage 20 includes: carriage side plate 21, carriage bottom plate 22, and carriage reinforcing rib plate 23;

[0099] The probe bracket 311 is fixed to the slide side plate 21, and the probe body 315 is slidably inserted through the slide side plate 21;

[0101] One end of the carriage reinforcing rib plate 23 is fixed to the carriage side plate 21, and the other end of the carriage reinforcing rib plate 23 is fixed to the carriage bottom plate 22.

[0102] In this embodiment, the connection strength between the carriage side plate 21 and the carriage bottom plate 22 is enhanced by using the carriage reinforcing rib plate 23.

[0103] Further according to this embodiment, the proximity switch 32 is fixed to the carriage base plate 22 by a sensing bracket 34. The sensing bracket 34 includes a sensing support plate 341 and a sensing connection support plate 342; the sensing support plate 341 is fixed to the carriage base plate 22, the sensing connection support plate 342 is vertically fixed to the sensing support plate 341, and the proximity switch 32 vertically penetrates the surface of the sensing connection support plate 342.

[0104] Specifically, the inductive connection support plate 342 is provided with an inductive mounting keyhole 3421, which is in the shape of a straight line in the horizontal direction. This is to facilitate fine adjustment of the mounting position of the proximity switch 32 in the horizontal direction, and to facilitate adjustment according to the thrust sensed by the probe body 315, ensuring that the proximity switch 32 can fully sense the movement and changes of the probe baffle 316.

[0105] Specifically, the first bracket leg 3111 is fixedly connected to the carriage side plate 21.

[0106] Reference Figure 1 , Figure 2 and Figure 4 The lifting guide component 13 includes: a lifting guide bearing 131 and a lifting guide rod 132;

[0107] The lifting guide bearing 131 is fixed through and fixed to the lifting fixing frame 11;

[0108] The lifting guide rod 132 is slidably inserted through the lifting guide bearing 131, and one end of the lifting guide rod 132 is fixed to the base plate of the lifting slide 20.

[0109] In this embodiment, the lifting guide bearing 131 and the lifting guide rod 132 are used to limit the lifting driving direction of the lifting drive component 12. In addition, the lifting guide bearing 131 is used to prevent the sliding of the lifting guide rod 132 from causing wear to the lifting fixed frame 11.

[0110] Reference Figure 1 , Figure 2 and Figure 4 The lifting guide bearing 131 includes: a lifting bearing through cylinder 1311, a lifting bearing mounting plate 1312, and a lifting bearing guide cylinder 1313;

[0112] The lifting bearing mounting plate 1312 is fixedly connected to the lifting fixing frame 11;

[0114] The lifting guide rod 132 is slidably inserted through the lifting bearing guide cylinder 1313 and the lifting bearing through cylinder 1311.

[0115] In this embodiment, the lifting bearing guide cylinder 1313 and the lifting fixing frame 11 are installed and fixed using the lifting bearing through cylinder 1311 and the lifting bearing mounting plate 1312; the lifting bearing through cylinder 1311 and the lifting bearing guide cylinder 1313 restrict the guiding direction of the lifting guide rod 132 and also prevent the sliding of the lifting guide rod 132 from causing wear to the lifting fixing frame 11.

[0117] In this application, when the blocking device for stopping the transported material is in working condition, the driving end of the lifting drive 12 extends and drives the lifting slide 20 to rise to a specified height. Under the drive of the lifting slide 20, the probe assembly 30 also rises to a specified height, which is the same height as the material. When the material is transported to the vicinity of the probe body 315, the material contacts the probe body 315, and the probe body 315 is pushed and retracts into the slide side plate 21 of the lifting slide 20. Then the proximity switch 32 senses the probe baffle 316, and finally controls the material to stop moving according to the sensing information of the proximity switch 32. At this time, the material is in place and is stopped.
