Description

Technical Field

[0001] The utility model relates to the technical field of transport chain equipment, and particularly relates to a transport chain blocking mechanism. Background Art

[0002] A transport chain is generally used to transport products on one working station to the next working station. Since the transport chain is in a state of continuously transporting products, when the products on the next working station cannot be processed in time, it will cause an excessive accumulation of products on the transport chain, increasing the working load of the transport chain, damaging the motor, and even more seriously, deforming the transport chain by extrusion.

[0003] It can be seen that the prior art still needs to be improved. Content of the Utility Model

[0004] In view of the deficiencies of the above prior art, the purpose of the utility model is to provide a transport chain blocking mechanism, aiming to solve the technical problem of excessive products accumulating on the transport chain.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A transport chain blocking mechanism includes a frame, a mounting seat, a baffle and a plug pin. The mounting seat is arranged on the frame. The middle part of the baffle is rotatably connected to the mounting seat. The center of gravity of the baffle is located at its lower part, so that the baffle automatically returns to the vertical state after swinging; a positioning hole matching the plug pin is arranged on the mounting seat, and the plug pin is inserted into the positioning hole to lock the baffle in the vertical state.

[0007] Further, the mounting seat is a horizontally placed U-shaped structure. The baffle is located inside the mounting seat, and a notch for avoiding the swing of the baffle is arranged on one side of the mounting seat.

[0008] Further, a stop block is arranged at one end of the plug pin.

[0009] Further, there are two baffles, and the two baffles are symmetrically arranged.

[0010] Further, the thickness of the upper part of the baffle is smaller than that of the lower part of the baffle.

[0011] Further, the frame includes a portal frame, an inclined support frame and a rib plate fixed between the portal frame and the support frame. The upper end of the support frame is fixedly connected to the portal frame, and the lower end of the support frame is on the same horizontal plane as the bottom of the portal frame.

[0012] Further, the cross sections of the portal frame and the support frame are C-shaped structures.

[0013] Further, it further includes a sensor and a counter. The sensor is disposed on the top of the frame and is used to detect the position of the product, and the counter is used to count the products detected by the sensor.

[0014] Further, the sensor is a travel switch.

[0015] Beneficial effects: The transportation chain blocking mechanism provided by the present utility model is provided with a swinging baffle. When the product passes by, it pushes the baffle, and the baffle swings. At this time, the product passes smoothly, and then the baffle automatically returns to the vertical state due to its own weight; when the plug pin is correspondingly inserted into the positioning hole to lock the baffle in the vertical state, the baffle cannot swing, so as to play a role in blocking the product from passing through, avoiding excessive products from continuing to be conveyed forward and piling up on the transportation chain.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4The utility model provides a transport chain blocking mechanism, which is placed between two adjacent transport chains to prevent excessive products from entering the next transport chain from the previous transport chain and being piled up. The transport chain blocking structure includes a frame 1, a mounting seat 2, a baffle 3 and a latch 4. The mounting seat 2 is arranged on the frame 1, the middle part of the baffle 3 is rotatably connected to the mounting seat 2, and the center of gravity of the baffle 3 is located at the lower part thereof, so that the baffle 3 automatically returns to a vertical state after swinging; the mounting seat 2 has a positioning hole 21 that matches the latch 4, and the latch 4 is inserted into the positioning hole 21 to lock the baffle 3 in a vertical state.

[0024] In actual use, Figure 4 As shown in the figure, the product driven forward by the transport chain passes through the baffle 3, and the baffle 3 swings due to the thrust. At this time, the product passes through the baffle 3 smoothly. Since the center of gravity of the baffle 3 is located at its lower part, the baffle 3 returns to the vertical state due to its own weight. Figure 1 As shown, the staff inserts the pin 4 into the positioning hole 21 accordingly, so that the side wall of the baffle 3 abuts against the peripheral wall of the pin 4, so that the baffle 3 cannot swing, so as to limit the baffle 3 in a vertical state. At this time, the baffle 3 blocks the product from continuing to be conveyed forward, so as to avoid excessive products from continuing to be conveyed forward and accumulating on the transport chain.

[0025] It should be noted that the transport chain is not drawn in the accompanying drawings.

[0026] In a preferred embodiment, see Figure 2 The mounting seat 2 is a horizontally placed U-shaped structure, the baffle 3 is located in the mounting seat 2, a notch 22 is provided on one side of the mounting seat 2 for avoiding the swing of the baffle 3, the middle part of the baffle 3 is rotatably connected with the two sides of the mounting seat 2 through a rotating shaft, and the mounting seat 2 with a U-shaped structure is provided to improve the stability of the installation of the baffle 3. When the product is transported forward, the baffle 3 is pushed, and the upper part of the baffle 3 swings toward the notch 22, and the product passes through the baffle 3 smoothly. When the baffle 3 is self-repositioned, the side wall of the mounting seat 2 below the notch 22 is limited to prevent the baffle 3 from swinging in the opposite direction due to inertia, so that the baffle 3 can quickly return to the vertical state.

[0027] In this embodiment, coaxially arranged positioning holes 21 are respectively provided on the corresponding two sides of the mounting base 2, and the latch 4 is inserted into the two positioning holes 21 to ensure the stability of the installation of the latch 4, thereby more stably defining the position of the baffle 3.

[0028] Preferably, see Figure 2 A stopper 41 is provided at one end of the latch pin 4, and the stopper 41 cannot pass through the positioning hole 21, so as to prevent the latch pin 4 from moving too far and falling out of the positioning hole 21 during the insertion of the latch pin 4.

[0029] In a preferred embodiment, see Figure 2, there are two baffles 3, and the two baffles 3 are symmetrically arranged. Similarly, there are two mounting seats 2, and one mounting seat 2 is correspondingly arranged with one baffle 3. Through the above settings, a better blocking effect on the product is achieved.

[0030] In a preferred embodiment, refer to Figure 3 , the thickness of the upper part of the baffle 3 is smaller than the thickness of the lower part of the baffle 3, so that the center of gravity of the baffle 3 is located in its lower part. After the baffle 3 swings under the thrust of the product, it can automatically return to the vertically placed state due to its own weight.

[0031] Optionally, the length of the lower part of the baffle 3 is longer than the length of its upper part, which can also make the center of gravity of the baffle 3 located in its lower part.

[0032] Optionally, a counterweight is provided at the lower part of the baffle 3, which can also make the center of the baffle 3 located in its lower part.

[0033] In a preferred embodiment, refer to Figure 1 、 2 , the frame 1 includes a portal frame 11, an inclined support frame 12 and a rib plate 13 fixed between the portal frame 11 and the support frame 12. The upper end of the support frame 12 is fixedly connected to the portal frame 11, and the lower end of the support frame 12 is on the same horizontal plane as the bottom of the portal frame 11. Specifically, bottom plates 14 are respectively connected to the lower end of the support frame 12 and the bottom of the portal frame 11, and several bottom plates 14 are fixed to the ground by screws. Through the above settings, the structural strength and installation stability of the frame 1 can be ensured.

[0034] Furthermore, the cross-sections of the portal frame 11 and the support frame 12 are C-shaped structures, that is, the portal frame 11 and the support frame 12 are made of C-shaped steel channels to further ensure the structural strength of the frame 1.

[0035] Optionally, the portal frame 11 and the support frame 12 are made of rectangular steel channels.

[0036] Even further, the support frame 12 is an H-shaped structure to ensure the structural strength of the support frame 1, and thus improve the structural strength of the frame 1.

[0037] In a preferred embodiment, refer to Figure 1 、 5 , it further includes a sensor 5 and a counter 6. The sensor 5 is arranged on the top of the frame 1 and is used to detect the position of the product, and the counter 6 is used to count the products detected by the sensor 5. Specifically, the sensor 5 is a travel switch. When the baffle 3 passes by the travel switch, the travel switch generates a signal. After the product passes by the baffle 3, the counter 6 counts to count the number of products passing through.

[0038] Among the above, it further includes a controller 7, which is electrically connected to the sensor 5 and the counter 6. The controller 7 can be the controller 7 of the transport chain. When the product passes by the baffle 3, it triggers the sensor 5 to generate a signal. The sensor 5 sends the signal to the controller 7, and the controller 7 controls the value of the counter 6 to increase by one, so that the counter 6 counts the number of products passing through. When the accumulated value of the counter 6 reaches the number of products that the transport chain can bear, the staff can insert the bolt 4 into the positioning hole 21 correspondingly to block the products behind from entering the transport chain. In the next working cycle, the staff pulls out the bolt 4, and the products behind are conveyed forward. After the counter 6 is reset, it starts counting again.

[0039] Preferably, a warning light 8 is provided beside the frame 1. The warning light 8 is electrically connected to the controller 7. When the value of the counter 6 reaches the preset value, the warning light 8 lights up to remind the staff.

[0040] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution and the inventive concept of the present utility model, and all such changes or substitutions should fall within the protection scope of the present utility model.
