In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] One aspect of the utility model provides a label paper conveying device, specifically as follows Figure 1 to Figure 2 As shown, the trademark paper conveying device includes a horizontal conveying unit 10, which includes a conveying frame 11, on which a conveying belt 12 is provided, and along the conveying direction of the conveying belt 12, a discharge paper warehouse 110 is provided at the end (left end) of the conveying belt 12; a driving motor (not shown in the figure), which is used to drive the conveying belt 12 to rotate; a feeding unit 20, which is arranged at the end of the conveying belt 12, specifically, the feeding unit 20 includes a first servo motor 21, a second servo motor 22 and a shovel plate 23, wherein the second servo motor 22 is connected to the first servo motor 21, and the shovel plate 23 is connected to the second servo motor 22, the first servo motor 21 can drive the shovel plate 23 to perform horizontal reciprocating motion, and the second servo motor 22 can drive the shovel plate 23 to perform vertical reciprocating motion; a control unit, the first servo motor 21 and the second servo motor 22 are both electrically connected to the control unit.

[0033] When the trademark paper conveying device of the utility model is used, the shovel plate 23 is first connected to the conveying end of the conveyor belt 12 of the horizontal conveying unit 10 by driving the first servo motor 21 and the second servo motor 22, so that the conveyor belt 12 is driven by the driving motor to rotate, and the trademark paper stack conveyed on the conveyor belt 12 can be conveyed to the shovel plate 23, and then the second servo motor 22 drives the shovel plate 23 to vertically descend, so as to convey the trademark paper stack to the discharge paper library 110. Since the servo motor is controlled by the control unit to drive the shovel plate 23 to feed the material in the present application, when the shovel plate 23 collides and squeezes when conveying the trademark paper stack, the servo motor will automatically stop to protect the safety of the device and the operator, and the control unit can make the servo motor return to the initial position according to the reverse process of the original process, and if the trademark paper conveying device is suddenly powered off or the device stops during operation, the first servo motor and the second servo motor will maintain the original phase, and after powering on again or resetting the fault information, it will continue to complete the original stroke to complete the feeding of the trademark paper stack. Therefore, compared with the prior art, the trademark paper conveying device of the utility model can automatically reset when collision, extrusion, shutdown and other faults occur, which can avoid human intervention, reduce labor intensity and labor costs, improve operating efficiency, and have higher safety.

[0034] Specifically, Figure 1 As shown, a material taking unit 30 is provided at the bottom of the outgoing paper storage 110 , and the material taking unit 30 is used to take out the trademark papers in the outgoing paper storage 110 one by one in sequence for subsequent operations.

[0035] Specifically, in this embodiment, a mounting bracket is provided on the conveying frame 11 , and in this embodiment, the first servo motor 21 is mounted on the mounting bracket.

[0036] Furthermore, in order to further improve the automation level of the label paper conveying device, Figure 2As shown, in this embodiment, a first sensor 201 is provided on one side of the discharge paper warehouse 110 and at a position higher than the conveying plane of the conveyor belt 12. The first sensor 201 is used to detect whether the horizontal conveying unit 10 transports the trademark paper stack on the conveyor belt 12 to the shovel plate 23, that is, when the shovel plate 23 is in a docking state with the end of the conveyor belt 12, the first sensor 201 detects whether there is a trademark paper stack on the shovel plate 23; a second sensor 202 and a third sensor (not shown in the figure) are provided on one side of the bottom of the discharge paper warehouse 100, and the second sensor 202 is higher than the third sensor, wherein the second sensor 202 is used to detect whether the material level in the discharge paper warehouse 110 reaches the feeding condition, and the third sensor is used to detect whether the material level in the discharge paper warehouse 110 is lower than the limit material level; the first sensor 201, the second sensor 202, the third sensor and the drive motor are all connected to the control unit. Through this design, during operation, when the first sensor 201 detects a trademark paper stack signal, it means that the horizontal conveying unit 10 has transported a trademark paper stack on the conveyor belt 12 to the shovel plate 23. At this time, the control unit controls the drive motor to stop driving the conveyor belt 12 to rotate based on the feedback signal of the first sensor 201; when the first sensor 201 and the third sensor both detect the trademark paper stack signal, and the second sensor 202 does not detect the trademark paper stack signal, it means that the trademark paper in the discharge paper library 110 is about to run out, that is, the feeding condition is met at this time, and the control unit controls the first servo motor and the second servo motor to drive the shovel plate 23 to move based on the feedback signals of the first sensor 201 and the second sensor 202, and has transported the trademark paper stack on the shovel plate 23 to the discharge paper library for feeding.

[0037] Specifically, Figure 2 As shown, in the present embodiment, when the shovel plate 23 is connected to the end of the conveyor belt 12, the shovel plate 23 is just above the discharge paper bin 110. When the trademark paper is transported into the discharge paper bin 110, the shovel plate 23 is driven vertically downward by the second servo motor 22 to transport the trademark paper stack on the shovel plate 23 to the discharge paper bin 110. After the shovel plate 23 transports the trademark paper stack to the right position, the shovel plate 23 is driven horizontally by the first servo motor 21 to pull the shovel plate 23 out of the discharge paper bin 110, and then the shovel plate 23 is driven to dock with the end of the conveyor belt 12 by the cooperation of the first servo motor 21 and the second servo motor 22.

[0038] Specifically, during the operation, if the third sensor does not detect the trademark paper, that is, the trademark paper level in the discharge paper bin 110 is lower than the limit level, it means that the feeding unit 20 has not fed the material into the discharge paper bin 110 in time. At this time, the control unit will immediately control the conveying device to stop and send a fault signal.

[0039] Furthermore, in this embodiment, a fourth sensor is provided on the conveying frame 11, and the fourth sensor is used to detect whether there is a pile of trademark paper on the conveyor belt 12. During operation, when the fourth sensor does not detect trademark paper information, it means that there is no pile of trademark paper on the conveyor belt 12, and at this time, the staff will be reminded to add materials to the conveyor belt 12 in time.

[0040] Furthermore, during the operation, when neither the second sensor 202 nor the fourth sensor detects the trademark paper information, it means that the trademark paper material level has been used up, and the control unit will control the conveying device to stop.

[0041] Furthermore, in this embodiment, a fifth sensor is provided at the end of the conveyor belt, and the fifth sensor is also connected to the control unit. The fifth sensor is used to detect whether the stack of trademark paper transported from the conveyor belt 12 to the shovel board 23 falls over. During operation, when the fifth sensor detects that the trademark paper falls over, the control unit will immediately control the conveying device to stop.

[0042] Specifically, in this embodiment, the control unit includes a servo controller and a servo driver connected to the servo controller, and the servo driver is connected to the first servo motor 21 and the second servo motor 22 .

[0043] Another aspect of the present invention provides a tobacco packaging machine, which includes the above-mentioned label paper conveying device. Specifically, the beneficial effects of the tobacco packaging machine are the same as those of the above-mentioned label paper conveying device, so they will not be described in detail here.

[0044] In summary, the trademark paper conveying device and tobacco packaging machine of the utility model can automatically reset when a collision, extrusion, shutdown or other faults occur, which can avoid human intervention, reduce labor intensity and labor costs, improve operating efficiency, and have higher accuracy, precision and safety. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
