[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be further described in detail below with reference to the drawings.

[0030] The embodiments of the utility model provide a filter rod disc conveying device for conveying filter rod discs 3, as shown in Figure 1 and Figure 2 , the conveying device comprises a belt conveyor 1, two lifting mechanisms 4, a first sensor 7 and a control system. Among them, the output end of the belt conveyor 1 is provided with a baffle 2, and the baffle 2 is used to block the filter rod disc 3, so that the filter rod disc 3 is buffered on the belt conveyor 1. Two lifting mechanisms 4 are respectively arranged on both sides of the belt conveyor 1 along the width direction of the belt conveyor 1 (as shown in the X direction in Figure 1 and Figure 2 ), and each lifting mechanism 4 is arranged close to the output end; the lifting mechanism 4 comprises a supporting plate 6, and the supporting plate 6 can move up and down between a first position and a second position. When the supporting plate 6 is located at the first position, the upper surface of the supporting plate 6 is higher than the upper surface of the conveying belt 5 of the belt conveyor 1. When the supporting plate 6 is located at the second position, the upper surface of the supporting plate 6 is lower than the upper surface of the conveying belt 5. Along the width direction of the belt conveyor 1, both ends of the filter rod disc 3 are located outside the conveying belt 5, and the projection of both ends of the filter rod disc 3 in the vertical direction falls on the supporting plate 6 of the two lifting mechanisms 4. The first sensor 7 is located on the upstream side of the lifting mechanism 4 along the conveying direction of the filter rod disc 3 (as shown in the Z direction in Figure 1 and Figure 2 ), and the control system is connected to the first sensor 7 and the two lifting mechanisms 4. Figure 2When the filter rod disc 3 passes the first sensor 7, the first sensor 7 can output a first signal. The control system is electrically connected with the first sensor 7 and the lifting mechanism 4, and can receive the first signal and count the number of the first signal. When the number of the first signal is equal to a first preset value, the control system can control the support plate 6 to move to the first position.

[0031] Specifically, the upstream device places the produced filter rod disc 3 on the input end of the conveyor belt 5, and the conveyor belt 5 drives the filter rod disc 3 to move to the output end. When the filter rod disc 3 passes the first sensor 7, the first sensor 7 outputs a first signal to the control system, and the control system determines the number of the filter rod disc 3 above the lifting mechanism 4 by counting the number of the first signal. When the filter rod disc 3 runs to the output end of the conveyor belt 5, the baffle 2 can block the filter rod disc 3 from falling off from the output end, so that the filter rod disc 3 remains on the conveyor belt 5. The filter rod disc 3 that reaches the output end first can block the subsequent filter rod disc 3, so that the filter rod disc 3 accumulates on the conveyor belt 5. When the control system receives the first signal reaching the first preset value, i.e., the number of the filter rod disc 3 accumulated above the driving mechanism reaches the first preset value, the control system controls the lifting mechanism 4 to move the support plate 6 to the first position, so as to lift the plurality of filter rod discs 3 above the support plate 6, preventing the filter rod discs 3 from generating pressure and friction on the conveyor belt 5. Subsequently, the filter rod discs 3 stay on the support plate 6 for a period of time to wait for the subsequent filter rod discs 3 to be buffered on the conveyor belt 5 one by one. When the buffered filter rod discs 3 on the conveyor belt 5 reach a preset number, the control system controls the lifting mechanism 4 to move the support plate 6 to the second position, so as to put the filter rod discs 3 on the support plate 6 back on the conveyor belt 5, and then the operator takes out the filter rod discs 3 buffered on the conveyor belt 5 together.

[0032] By using the above technical scheme, the lifting mechanism 4 can be used to lift the filter rod disc 3 accumulated on the output end in the early stage, so that the filter rod disc 3 is separated from the conveyor belt 5 in the process of waiting for the filter rod disc 3 accumulated in the late stage, thereby preventing the filter rod disc 3 on the conveyor belt 5 from generating too much pressure and friction on the conveyor belt 5, and prolonging the service life of the conveyor belt.

[0033] Further, the lifting mechanism 4 includes a cylinder 8 and the support plate 6. The cylinder 8 is arranged on the side of the belt conveyor 1. The support plate 6 is connected with the driving end of the cylinder 8, and the cylinder 8 is used to drive the support plate 6 to move between the first position and the second position. Specifically, the electric control unit of the cylinder 8 is electrically connected with the control system, and the control system can control the driving end of the cylinder 8 to extend when the number of the first signal is equal to the first preset value, so as to drive the support plate 6 to move to the first position. In addition, the control system can control the cylinders 8 of the lifting mechanisms 4 on both sides of the conveyor belt 5 to start and stop at the same time, so as to prevent the filter rod disc 3 from tilting in the width direction.

[0034] Furthermore, the lifting mechanism 4 includes two cylinders 8, which are positioned along the length of the belt conveyor 1. Figure 1 and Figure 2 The two cylinders 8 are spaced apart (as shown in the Y direction); and they are respectively located near the two ends of the support plate 6 along its length. Specifically, the two cylinders 8 are of the same model and have the same installation height, and the control system can control the two cylinders 8 to start and stop simultaneously. Using two cylinders 8 to support the two ends of the support plate 6 can improve the stability of the support plate 6 and prevent the support plate 6 from shaking and tilting.

[0035] Furthermore, the control system includes a first counter electrically connected to a first sensor 7. The first counter increments by 1 upon receiving a first signal and resets to zero when the number of first signals exceeds a first preset value. Specifically, the first preset value is 8, and the detection end of the first sensor 7 faces the buffer position of the 9th filter rod disk 3. After the first 8 filter rod disks 3 reach the output end, they are arranged in sequence abutting against each other. At this time, the lifting mechanism 4 lifts these 8 filter rod disks 3 to a first position, disengaging them from the conveyor belt 5. When the 9th filter rod disk 3 reaches the output end, it abuts against the 8th filter rod disk 3. At this time, the first detector detects the 9th filter rod disk 3 and outputs a first signal. The first counter automatically resets to zero upon receiving the 9th first signal, so as to continue counting after the conveyor belt 5 is emptied. Since the 9th filter rod disk 3 remains within the detection area of ​​the first sensor 7, the first sensor 7 no longer outputs a first signal before the 9th filter rod disk 3 leaves the detection area. When the filter rod discs 3 on conveyor belt 5 accumulate to the second preset value, the control system reminds the operator to remove all the filter rod discs 3 from conveyor belt 5, thus clearing the upper surface of conveyor belt 5. This cycle continues, with subsequent filter rod discs 3 accumulating at the output end, and the first counter begins the next round of counting.

[0036] Further, the conveying device further comprises a second sensor 9; the second sensor 9 is located on the upstream side of the first sensor 7 along the conveying direction of the filter rod disc 3, and the second sensor 9 can output a second signal when the filter rod disc 3 passes through the second sensor 9; the second sensor 9 is electrically connected with the control system, the control system can receive the second signal and count the number of the second signal; when the number of the second signal is equal to a second preset value, the control system can control the supporting plate 6 to move to the second position. Specifically, the second preset value is 15, when the accumulated filter rod discs 3 on the conveying belt 5 reach 15, the control system reminds the operator to take away the accumulated filter rod discs 3 on the conveying belt 5. The operator can use a manual, semi-automatic or automatic picking device to clamp 15 filter rod discs 3 at a time and move to the downstream process. When the accumulated filter rod discs 3 on the conveying belt 5 reach 15, the first to eighth filter rod discs 3 are located on the raised supporting plate 6, and the ninth to fifteenth filter rod discs 3 are located on the upper surface of the conveying belt 5. In order to facilitate the operator to clamp all the filter rod discs 3, it is necessary to place the first to eighth filter rod discs 3 on the conveying belt 5 in alignment with the ninth to fifteenth filter rod discs 3, so as to prevent the filter rod discs 3 from being unbalanced in force during clamping.

[0037] Further, the control system further comprises a second counter, the second counter is electrically connected with the second sensor 9, the second counter can count plus 1 when receiving the second signal, and clear zero when the number of the second signal is greater than the second preset value, so as to continue counting after the conveying belt 5 is emptied.

[0038] Further, the first sensor 7 and the second sensor 9 are both proximity switches, and the supporting plate 6 is made of steel plate.

Those skilled in the art can make various changes in form and details, including making a number of simple inferences or substitutions, without departing from the spirit and scope of the utility model.
