[0024] The following is combined with Figure 1-2 This application is described in further detail.

[0025] The present application discloses a device for preventing wrong insertion of a raw material distribution station, referring to Figure 1 The mis-insertion prevention device for the raw material distribution station includes a feed pipe 2 installed at intervals on the machine body 1, a discharge pipe 3 arranged at intervals and connected to the feed pipe 2, and a discharge pipe 4 detachably connected to the discharge pipe 3. There are multiple discharge pipes 4, which are used to transport materials from the discharge pipe 3 to a designated processing position. When transporting materials, the corresponding discharge pipe 4 and the discharge pipe 3 are first connected, and then the negative pressure is used to discharge the materials into the discharge pipe 3 through the feed pipe 2, and after being discharged into the discharge pipe 4 through the discharge pipe 3, the discharge pipe 4 transports the materials to the designated processing position.

[0026] Reference Figure 1 The machine body 1 is generally a rectangular parallelepiped structure, and there are four feed pipes 2 arranged at equal intervals along the width direction of the machine body 1. The feed pipes 2 are arranged obliquely in the machine body 1, so that the bottom end of the feed pipe 2 is located at a wide side of the machine body 1. There are five discharge pipes 3 located on one feed pipe 2, and the top end of the feed pipe 2 is coaxially connected to a transition pipe 5 connected to one of the discharge pipes 3.

[0027] Reference Figure 1 , the axial direction of the discharge pipe 3 is arranged along the vertical direction. A plug 6 is detachably connected to the top of each discharge pipe 3. When the discharge pipe 3 is not in use, the plug 6 is used to close the pipe opening of the discharge pipe 3. A connecting chain 61 is fixed to the outer wall of the plug 6. A connecting ring 62 is installed at one end of the connecting chain 61 away from the plug 6. The inner diameter of the connecting ring 62 is larger than the outer diameter of the discharge pipe 3. The connecting ring 62 is used to sleeve the discharge pipe 3, so that the plug 6 can be detachably connected to the discharge pipe 3. In addition, when the plug 6 is not in use, the plug 6 is hung on the discharge pipe 3 by using the connecting ring 62 and the connecting chain 61 to place the plug 6.

[0028] Reference Figure 1 , a locking piece 7 is provided at the connection between the discharge pipe 4 and the discharge pipe 3. During installation, the discharge pipe 4 and the discharge pipe 3 are coaxially connected through the locking piece 7. The locking piece 7 includes a coaxial sleeve 71 provided on the sleeve 71 of the discharge pipe 3, two semi-annular connecting plates 72, two sets of fixing bolts 73 and fixing nuts 74. Among them, the sleeve 71 is made of plastic and has a certain elasticity and deformability. And when installing the plug 6, the plug 6 can be sleeved on the sleeve 71 so that the sleeve 71 is located in the inner cavity of the plug 6. The connecting plate 72 has a groove 721 for fitting the outer wall of the discharge pipe 4 and the outer wall of the discharge pipe 3 for installation. Fixed blocks 722 are respectively extended at both ends of the connecting plate 72, and the fixing bolts 73 are penetrated through the fixing blocks 722. During installation, the fixing nut 74 is threadedly connected to the fixing bolt 73 until the side wall of the fixing nut 74 abuts against the side wall of the fixing block 722.

[0029] Reference Figure 1Each discharge pipe 4 is provided with a different identification label 8, and the identification label 8 is located on the connecting plate 72. A mounting block 723 is fixed to the outer wall of one of the connecting plates 72, and a mounting groove 7231 is provided at the bottom of the mounting block 723, and the mounting groove 7231 is for the identification label 8 to be pasted. When pasted, the identification label 8 is located on the top wall of the mounting groove 7231. In addition, one side of the mounting groove 7231 penetrates to the outer wall of the mounting block 723.

[0030] Reference Figure 1 The discharge pipe 3 is provided with an identification member for identifying the identification label 8 located on the discharge pipe 4. The identification member is a code reading sensor 9 for reading the content on the identification label 8. The body 1 is equipped with a plurality of eight-port distributors 10, and one interface on the distributor 10 corresponds to a connection line (including a signal line) connected to a code reading sensor 9. The bus of the distributor 10 is connected to the PLC control system, which performs identification and judgment, and then outputs the results to the computer for manual viewing.

[0031] Reference Figure 1 Furthermore, the discharge pipe 3 is coaxially connected with two semicircular clamps 11 for installing the code reading sensor 9. The semicircular clamp 11 is located between the shaft sleeve 71 and the connecting ring 62, and the two ends of the semicircular clamp 11 are respectively fixed with connecting blocks 111; the connecting block 111 is generally an arch bridge structure, so that the middle position of the connecting block 111 has a clamping groove 112 for plugging the code reading sensor 9. When installing the two semicircular clamps 11, after the screws are passed through the two adjacent connecting blocks 111, the nuts are threadedly connected to the screws to achieve locking. At this time, the two adjacent connecting blocks 111 abut against each other, and the outer wall of the code reading sensor 9 abuts against the inner wall of the clamping groove 112.

[0032] Reference Figure 1 In addition, during installation, the side wall of the connecting block 111 abuts against the inner wall of the installation groove 7231 to limit the circumferential position of the two connecting plates 72. The top of the code reading sensor 9 is completely accommodated in the installation groove 7231, and a certain distance is left between the code reading sensor 9 and the identification label 8 to facilitate reading the content on the identification label 8.

[0033] The implementation principle of the anti-misinsertion device for a raw material distribution station in an embodiment of the present application is as follows: before installation, the mounting block 723 on the discharge pipe 4 is first mounted on the code reading sensor 9, and the code reading sensor 9 is used to read the content of the identification label 8 located on the top wall of the mounting groove 7231, and then the read data is transmitted to the PLC control system through the distributor 10 for judgment, and the PLC control system outputs the judgment result to the computer for manual review. After confirmation, the discharge pipe 3 and the discharge pipe 4 can be connected, thereby improving the problem that the discharge pipe 4 is inserted into the discharge pipe 3 incorrectly, resulting in non-specified materials being delivered to the processing position or the materials being delivered to a non-specified processing position, affecting the processing.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
