It should be specially noted that the ring chain plate conveyor 1 in this application is a prior art, which will not be described in detail here.

[0034] See attached Figure 2 — Figure 4 As shown, in the utility model, the storage seat 2 includes a mounting seat 21 mounted on the ring chain conveyor 1, a connecting plate 22 mounted on the mounting seat 21, and the gear sensing structure 3 is mounted on the connecting plate 22.

It should be particularly noted that the mounting seat 21 is a prior art, that is, it matches the existing ring chain conveyor 1 and is installed on the conveying chain plate of the ring chain conveyor 1.

[0036] See attached Figure 4 — Figure 7 As shown, in the utility model, the gear sensing structure 3 includes a wireless weighing sensor 31 installed at the middle position of the installation groove 23, a movable base 32 movably installed in the installation groove 23 and in contact with the wireless weighing sensor 31, a connecting structure 33 installed on the movable base 32, and a limit block 34 detachably installed on the connecting structure 33 and located at the top of the movable base 32. The wireless weighing sensor 31 is connected to the PLC controller 7.

[0037] The utility model can monitor whether a semi-finished product is placed on the movable base 32 and ensure whether there are semi-finished products stored on the storage seat 2 by setting a wireless weighing sensor 31; the movable base 32 can be raised and lowered along the mounting groove 23 by setting the movable base 32, thereby ensuring that the pressure of the movable base 32 is applied to the wireless weighing sensor 31, ensuring that the wireless weighing sensor 31 can monitor whether there are semi-finished products placed; and the connection structure 33 is provided to provide an installation position for the limit block 34. Xu Yaoao specifically pointed out that the wireless weighing sensor 31 used in this application is connected to the PLC controller 7 by wireless transmission, so that there is no need for line connection between the wireless weighing sensor 31 and the PLC controller 7, thereby effectively preventing the storage seat 2 from getting tangled in the line during the cyclic movement, and ensuring the normal operation of the device.

[0038] See attached Figure 4 — Figure 7 As shown, in the utility model, a semicircular groove 321 is provided on the side wall of the movable base 32, a ball 322 is installed in the semicircular groove 321, an arc-shaped limiting plate 323 is installed on the connecting structure 33, and a limiting through groove 324 corresponding to the ball 322 is provided on the arc-shaped limiting plate 323; a covering plate 231 is installed at the notch of the mounting groove 23.

[0039] The utility model provides an installation position for the ball 322 by setting a semicircular groove 321; the friction between the movable base 32 and the groove wall of the installation groove 23 is reduced by setting the ball 322; the position of the ball 322 can be limited by setting the arc-shaped limiting plate 323 to prevent the ball 322 from separating from the semicircular groove 321; the ball 322 is avoided by setting the limiting through groove 324 to ensure that the ball 322 can contact the groove wall of the installation groove 23; the movable base 32 can be limited by setting the covering plate 231 to prevent the movable base 32 from separating from the installation groove 23.

[0040] See attached Figure 4 — Figure 7 As shown, in the utility model, the movable base 32 is provided with a through groove 325 corresponding to the connecting structure 33, and the bottom of the movable base 32 is provided with an avoidance groove 326 connected with the through groove 325; the connecting structure 33 includes a horizontal plate 331 located in the avoidance groove 326, a vertical plate 332 installed on one end of the horizontal plate 331 and located in the through groove 325, and the other end of the horizontal plate 331 is connected to the arc-shaped limit plate 323; the vertical plate 332 is detachably connected to the limit block 34.

[0041] The utility model avoids the vertical plate 332 by setting the through groove 325, so that the vertical plate 332 can penetrate the movable base 32, so that the limit block 34 located at the top of the movable base 32 provides installation conditions; by setting the avoidance groove 326, the cross plate 331 is avoided and the installation position of the cross plate 331 is limited, and it should be particularly noted that the groove depth of the avoidance groove 326 is not less than the thickness of the cross plate 331, thereby ensuring that the bottom of the movable base 32 is in contact with the wireless weighing sensor 31; it should be particularly noted that the vertical plate 332 and the cross plate 331 are integrally processed and formed, and the arc-shaped limit plate 323 can be integrally processed and formed with the cross plate 331, and can also be fixed on the cross plate 331 by welding.

[0042] See attached Figure 4 — Figure 7 As shown, in the utility model, a magnet 333 is installed on the vertical plate 332, and the limit block 34 is made of magnetic conductive material. The bottom of the limit block 34 is provided with a matching groove 341 corresponding to the magnet 333 and the vertical plate 332, and the bottom of the limit block 34 is also provided with a handle groove 342; the groove width of the through groove 325 is greater than the thickness of the vertical plate 332.

[0043] The utility model provides a magnet 333 and a limitation that the limit block 34 is made of a magnetic conductive material, so that the limit block 34 can be detachably installed. It should be particularly noted that the friction between the semi-finished product and the limit block 34 is less than the maximum magnetic force between the limit block 34 and the magnet 333; the provision of the matching groove 341 allows the vertical plate 332 and the magnet 333 to drive the limit block 34 to move; the provision of the handle groove 342 facilitates the staff to replace the size of the limit block 34, so that it can be suitable for different gear semi-finished products, thereby expanding the scope of application of the present application; the width of the through groove 325 is greater than the thickness of the vertical plate 332, so that the vertical plate 332 can be moved in the through groove 325, so that the arc-shaped limit plate 323 can limit the ball 322.

[0044] See attached Figure 3 , Figure 8 — Fig.10 As shown, in the utility model, the signal receiver 4 is a laser receiver and is connected to the PLC controller 7; the material discharge signal structure 5 and the material pick-up signal structure 6 both include an L-shaped mounting plate 51, a lifting plate 52 installed on the L-shaped mounting plate 51, and a lifting structure 53 arranged on the L-shaped mounting plate 51 and the lifting plate 52.

[0045] The utility model arranges an L-shaped mounting plate 51 so that the mounting positions of the material picking laser emitter 61 and the material discharging laser emitter 54 are away from the moving track of the storage seat 2 to prevent interference with the storage seat 2; the lifting plate 52 is arranged to provide mounting positions for the material picking laser emitter 61 and the material discharging laser emitter 54; the lifting structure 53 is arranged to adjust the mounting heights of the material picking laser emitter 61 and the material discharging laser emitter 54 to ensure that they correspond to the signal receiver 4, that is, the L-shaped mounting plate 51 may be deformed or the mounting heights may be inconsistent when the L-shaped mounting plate 51 is installed, and therefore, adjustment is required through the lifting structure 53.

[0046] See attached Figure 8 — Fig.10 As shown, in the present invention, the material discharge signal structure 5 further includes a material discharge laser transmitter 54 installed on the lifting plate 52 in the material discharge signal structure 5; the material collection signal structure 6 further includes a material collection laser transmitter 61 installed on the lifting plate 52 in the material collection signal structure 6, and the material collection laser transmitter 61 and the material discharge laser transmitter 54 both correspond to the signal receiver 4. It should be particularly noted that the signal receiver 4 is a wireless laser signal receiver.

[0047] See attached Figure 8 — Fig.10 As shown, in the utility model, a lifting groove 511 corresponding to the lifting plate 52 is provided on the L-shaped mounting plate 51, a avoidance hole 512 connected to the lifting groove 511 is opened at the bottom of the L-shaped mounting plate 51, a lifting screw 521 corresponding to the avoidance hole 512 is provided at the bottom of the lifting plate 52, a spring 522 is sleeved on the lifting screw 521, and the spring 522 is located in the lifting groove 511. An adjusting nut 523 is also installed on the lifting screw 521, and the adjusting nut 523 is in contact with the bottom surface of the L-shaped mounting plate 51.

[0048] The utility model guides and limits the lifting and lowering movement of the lifting plate 52 by setting the lifting groove 511; avoids the lifting screw 521 by setting the avoidance hole 512, so that the lifting screw 521 passes through the bottom surface of the L-shaped mounting plate 51 and can cooperate with the adjusting nut 523; supports the lifting plate 52 by setting the spring 522, and by setting the adjusting nut 523, the lifting plate 52 can be pulled to move by the lifting screw 521 by screwing the adjusting nut.

[0049] The adjustment process of the lifting structure 53 in this application is as follows:

[0050] When the installation position of the material taking laser emitter 61 or the material discharging laser emitter 54 needs to be adjusted upward, the staff can screw the adjusting nut 523 to move the adjusting nut 523 away from the lifting plate 52. When the staff screws the adjusting nut 523, the spring 522 is in a compressed state, and the spring 522 is reset to push the lifting plate 52 upward, so that the installation position can be adjusted upward.

[0051] When the installation positions of the material picking laser emitter 61 and the material discharging laser emitter 54 need to be adjusted downward, the staff can screw the adjusting nut 523 to move the adjusting nut 523 toward the lifting plate 52. When the staff screws the adjusting nut 523, the adjusting nut 523 is limited by the L-shaped mounting plate 51 and cannot move upward, thereby causing the lifting screw 521 to move downward, and the lifting plate 52 moves downward to compress the spring 522.

[0052] See attached Figure 1 — Fig.10 As shown, the use process of the utility model is as follows:

[0053] When the front-end process is completed and the semi-finished product needs to be placed, the front-end process sends a placement signal, and the PLC controller 7 receives the front-end signal. The PLC controller 7 controls the circuit of the discharge laser transmitter 54 in the discharge signal structure 5 to be closed. When a signal receiver 4 receives the signal of the discharge laser transmitter 54, it transmits the signal to the PLC controller 7. The PLC controller 7 controls the ring chain conveyor 1 to stop working, and reads the data of the wireless weighing sensor 31 corresponding to the signal receiver 4. If the data of the wireless weighing sensor 31 is within the set data, that is, there is no semi-finished product placed on the storage seat 2, the PLC controller 7 controls the front end to start discharging. If the data of the wireless weighing sensor 31 exceeds the set data, that is, there is a semi-finished product placed on the storage seat 2, the PLC controller 7 restarts the ring chain conveyor 1 until the next signal receiver 4 receives the signal, and repeats this process until a storage seat 2 without a semi-finished product is sensed.

[0054] When the back-end process needs to pick up materials, the back-end process sends out a picking up material signal, and the PLC controller 7 receives the back-end signal. The PLC controller 7 controls the circuit closure of the picking up material laser transmitter 61 in the picking up material signal structure 6. When a signal receiver 4 receives the signal of the picking up material laser transmitter 61, it transmits the signal to the PLC controller 7. The PLC controller 7 controls the ring chain conveyor 1 to stop working, and reads the data of the wireless weighing sensor 31 corresponding to the signal receiver 4 at the same time. If the data of the wireless weighing sensor 31 exceeds the set data, that is, there is a semi-finished product placed on the storage seat 2, the PLC controller 7 controls the back end to start picking up materials. If the data of the wireless weighing sensor 31 does not exceed the set data, that is, there is no semi-finished product placed on the storage seat 2, the PLC controller 7 restarts the ring chain conveyor 1 until the next signal receiver 4 receives the signal, and repeats this process until the storage seat 2 with the semi-finished product is sensed.

[0055] The above embodiments are descriptions of the present application, not limitations of the present application. Any solution that is a simple transformation of the present application belongs to the protection scope of the present application.
