[0044] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0045] like Figure 1 and Figure 2 As shown, one embodiment of the utility model provides a cable tie cutting and collecting device for cutting and collecting cable ties 3 on the periphery of cigarette packs 2 on a roller conveyor 1. The roller conveyor 1 includes a plurality of cable ties 3 along a first direction (such as Figure 1 The conveying rollers 11 are arranged at intervals (in the X direction as shown), and the conveying rollers 11 can rotate around their own axes to convey the cigarette packs 2 along the first direction. The width direction of the roller conveyor is the second direction (as shown in the X direction). Figure 2 Y direction as shown), including: a cutting device, a collecting device and a control system (not shown in the figure).

[0046] The cutting device is arranged below the roller conveyor 1 , and comprises: a cutter 5 , a first detection switch 4 , a first driving mechanism and an elastic member 7 .

[0047] The cutter 5 is disposed between two adjacent conveying rollers 11. For example, the cutter 5 is a circular blade, the edge of which is provided with a blade, and the cutter 5 can rotate around its own axis. The circular blade rotates around its own center of circle driven by the first driving mechanism so that the blade cuts the cable tie 3.

[0048] The detection area of ​​the first detection switch 4 is the first detection area, the cutter 5 is located in the first detection area and downstream of the first detection switch 4 along the first direction, and the first detection switch 4 is used to detect whether there is a cigarette pack 2 in the first detection area. Exemplarily, the first detection switch 4 is a micro detection switch.

[0049] The first driving mechanism is connected to the cutter 5, and is used to drive the cutter 5 to rotate so as to cut the cable tie 3 passing over the cutter 5. Exemplarily, the first driving mechanism is a motor, and the operator can select the type of motor according to actual needs to provide power for the rotation of the cutter 5.

[0050] The elastic member 7 is disposed below the cutter 5 and the first driving mechanism, and the elastic member 7 can provide an upward supporting force for the cutter 5. Exemplarily, the elastic member 7 can be a compression spring 71.

[0051] When the cigarette pack 2 moves to the top of the cutter 5, the cigarette pack 2 contacts the cutter 5, and the cigarette pack 2 applies downward pressure to the cutter 5, so that the elastic member 7 retracts and generates elastic deformation. At this time, the cutter 5 rotates around its own axis to cut the cable tie 3 on the outer periphery of the cigarette pack 2. When the cigarette pack 2 is separated from the cutter 5, the elastic member 7 restores the elastic deformation to drive the cutter 5 to move upward. After the elastic member 7 restores the elastic deformation, the highest point of the cutter 5 is higher than the highest point of the conveying roller 11, so that when the next cigarette pack 2 passes above the cutter 5, the highest point of the cutter 5 can contact the cable tie 3.

[0052] The collecting device is disposed on one side of the cigarette pack 2 along the second direction. The collecting device comprises: a grasping mechanism for grasping the cut cable tie 3 to separate the cable tie 3 from the cigarette pack 2 .

[0053] The control system is used to receive a signal from the first detection switch 4 , wherein when the first detection switch 4 detects the cigarette pack 2 , the first detection switch 4 sends a signal to the control system, and the control system controls the cutter 5 to rotate and the gripping mechanism to move toward the cigarette pack 2 .

[0054] In response to the problems arising from the existing cable tie cutting and collection methods, the present application designs a cutting device, a collecting device and a control system, and utilizes the first detection switch 4 in the cutting device to identify and detect the cigarette pack 2 on the roller conveyor 1. When the control system receives a signal from the first detection switch 4, it indicates that the cigarette pack 2 is located in the first detection area. At this time, the first drive mechanism drives the cutter 5 to rotate to cut the cable tie 3 tied to the outside of the cigarette pack 2. At the same time, the control system controls the grasping mechanism to grasp the cut cable tie 3 for collection, thereby solving the problem of high labor intensity of the existing cable tie cutting and collection methods, improving the work efficiency of cable tie cutting and recycling, and improving the degree of automation in tobacco production.

[0055] Furthermore, after the tie 3 at the bottom of the cigarette pack 2 is cut off, the tie 3 at the top of the cigarette pack 2 will remain in the original position, and the grasping mechanism only needs to grasp the tie 3 at the top of the cigarette pack 2 to remove the tie 3 from the cigarette pack 2. Specifically, the grasping mechanism includes a manipulator 9, a retracting rod 10, a second detection switch and a second driving mechanism 12. Among them, the manipulator 9 is used to grasp the tie 3. One end of the retracting rod 10 is connected to the manipulator 9, and the retracting rod 10 can drive the manipulator 9 to move in a direction close to the cigarette pack 2 or away from the cigarette pack 2 along the second direction. The second detection switch is arranged on the manipulator 9, and the second detection switch is used to detect whether the grasping mechanism grasps the tie 3. The second driving mechanism 12 is connected to the other end of the retracting rod 10, and the second driving mechanism 12 is used to drive the retracting rod 10 to move in a direction close to or away from the cigarette pack 2, so that the tie 3 can be grasped by the manipulator 9 and detached from the cigarette pack 2. Exemplarily, the second detection switch is a travel detection switch. The second driving mechanism 12 is a cylinder, and the operator can select the type of the cylinder according to actual needs to provide power for the contraction of the contraction rod 10.

[0056] Specifically, when the entire production line starts working, the first detection switch 4 starts to detect whether there is a cigarette pack 2 being transported in the first detection area. When the first detection switch 4 does not detect that a cigarette pack 2 appears in its corresponding detection area, the first drive mechanism and the second drive mechanism 12 are both in a stopped working state, that is, the cutter 5 will not cut the cable tie 3 and the retracting rod 10 will not drive the manipulator 9 to collect the cable tie 3. When the first detection switch 4 detects that there is a cigarette pack 2 in the first detection area, the first detection switch will transmit a detection signal to the control system, and then the control system will control the first drive mechanism and the second drive mechanism 12 to work after receiving the detection signal, and then the first drive mechanism will drive the cutter 5 connected thereto to rotate. Since the cigarette pack 2 is located above the cutter 5 at this time, and the cable tie 3 can contact the blade of the cutter 5, the cutter 5 will cut the cable tie 3 during the rotation process. At the same time, the second drive mechanism 12 will drive the retracting rod 10 connected thereto to extend toward the cigarette pack 2, and the manipulator 9 connected to the retracting rod 10 will also follow the retracting rod 10 to extend toward the cigarette pack 2. Since the cigarette pack 2 is located on one side of the manipulator 9 at this time, and the second detection switch on the manipulator 9 can detect whether the manipulator 9 has grasped the cable tie 3, after the second detection switch detects that the manipulator 9 has grasped the cable tie 3, the second detection switch will transmit the detection signal to the control system, and then after receiving the detection signal, the control system will control the second drive mechanism 12 to work, and then the second drive mechanism 12 will control the retraction rod 10 to retract away from the cigarette pack 2 to complete the collection of the cable tie 3.

[0057] Furthermore, the cutting device further comprises a first fixed seat 6 and a second fixed seat 8. The first fixed seat 6 is arranged on the frame of the roller conveyor 1. The second fixed seat 8 is arranged above the first fixed seat 6, and the cutter 5 is rotatably arranged on the second fixed seat 8. The elastic member 7 is arranged between the first fixed seat 6 and the second fixed seat 8, and the elastic member 7 can provide an upward supporting force for the first fixed seat 6 and the cutter 5.

[0058] The present application arranges an elastic member 7 between the first fixing seat 6 and the second fixing seat 8. When a cigarette pack 2 is transported above the cutter 5, the elastic member 7 utilizes its own elastic deformation property to move the cutter 5 downward by a certain distance, thereby providing a buffer for the cutter 5 and preventing the cutter 5 from being damaged by excessive collision with the cigarette pack 2.

[0059] Specifically, the collecting device further includes a collecting container for storing the collected cable ties 3. The manipulator 9 can put the captured cable ties 3 into the collecting container, which is convenient for subsequent collection and sorting by the staff.

[0060] Further, refer to Figure 3 and Figure 4 The cutting device further comprises a protective cover 51 and a third driving mechanism. The protective cover 51 is arranged on the frame of the roller conveyor 1. The third driving mechanism is connected to the protective cover 51, and the third driving mechanism is used to drive the protective cover 51 to be able to move relative to the cutter 5 in the first position (such as Figure 3 The protective cover 51 is located in the position shown) and the second position (as shown Figure 4 The protective cover 51 is shown in the position where it is located);

[0061] When the protective cover 51 rotates to the first position, the cutter 5 is located outside the protective cover 51; when the protective cover 51 rotates to the second position, the cutter 5 is covered inside the protective cover 51. Exemplarily, the third driving mechanism is a motor, and the operator can select the type of motor according to actual needs to provide power for the rotation of the protective cover 51.

[0062] The utility model of the automatic cable tie cutting device is provided with a protective cover 51 and a third driving mechanism connected thereto at the edge of the cutter 5. When the first detection switch 4 detects that a cigarette pack 2 appears in its corresponding detection area, the two detection switches will transmit the detection signal to the control system, and then the control system will control the third driving mechanism to work after receiving the detection signal, and then the third driving mechanism will drive the protective cover 51 to rotate to the first position, at which time the cutter 5 is located outside the protective cover 51. When the first detection switch 4 does not detect that a cigarette pack 2 appears in its corresponding detection area, the third driving mechanism drives the protective cover 51 to rotate to the second position, that is, the protective cover 51 covers the cutter 5 inside. This design can prevent the cutter 5 from causing harm to the staff when it is accidentally started, thereby improving the safety of the device.

[0063] Based on the same concept, the utility model also provides a cable tie cutting and collecting assembly line, characterized in that it comprises: a roller conveyor 1 and the cable tie cutting and collecting device mentioned in any of the above embodiments, the roller conveyor 1 is used to convey the cigarette packs 2 to the cable tie cutting and collecting device.
