Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging production technology, and in particular to a transmission line for cigarette storage. Background Technology

[0002] In automated cigarette finished product logistics systems, finished cigarettes are stored in automated warehouses in palletized stacks. After packaging, the cigarette cartons are packed into cigarette boxes, which are then conveyed into the warehouse. Palletizing robots stack these boxes. In actual use, cigarette boxes may shift during transport, resulting in inconsistent relative positions when they reach the front of the palletizing robot. This often leads to box crushing, causing product damage, downtime, and disruption of production continuity. It also results in low palletizing efficiency. Furthermore, sometimes the boxes are squeezed together, causing the palletizing robot to misalign subsequent boxes during pickup, leading to malfunctions in the next pickup. Utility Model Content

[0003] The technical problem to be solved by this utility model is to address the above-mentioned shortcomings of the existing technology by providing a conveyor line for cigarette storage that automatically and neatly arranges cigarette boxes, making it easier for palletizing robots to grasp them, reducing the occurrence of malfunctions, and has the characteristics of wide applicability and strong practicality.

[0004] The technical solution adopted by this utility model is: a conveyor line for cigarette loading, including a conveyor support frame. One end of the conveyor support frame is provided with a plurality of first conveyor rollers. The conveyor support frame at the front end of the first conveyor rollers is provided with a plurality of forward-inclined first inclined rollers. The conveyor support frame at the front end of the first inclined rollers is provided with a plurality of backward-inclined second inclined rollers. The conveyor support frame at the front end of the second inclined rollers is provided with a second conveyor roller. The conveyor support frames on both sides of the second conveyor rollers are provided with blocking devices for separating the cigarette boxes. A guide assembly is provided on one side above the first inclined rollers.

[0005] As a further improvement, transition rollers are provided on both sides of the first inclined roller and the second inclined roller.

[0006] Furthermore, each of the conveyor support frames on one side of the transition roller is equipped with a photoelectric sensor, which is electrically connected to an external PLC controller.

[0007] Furthermore, the blocking device includes a mounting base, an electric push rod, and two rotating rods. The mounting base is mounted on the conveying support frame via a support plate. One end of each of the two rotating rods is rotatably mounted on the mounting base via a rotating shaft. Electric push rods are provided on both sides of the mounting base, and the output end of the electric push rod is rotatably connected to the middle position of the rotating rod.

[0008] Furthermore, the rotating rod is provided with a plurality of linearly arranged rotating wheels.

[0009] Furthermore, the guiding assembly includes a crash barrier and multiple guide wheels. The crash barrier is mounted on a conveying support frame on one side of the first inclined roller, and the multiple guide wheels are arranged linearly on the crash barrier.

[0010] Beneficial effects

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] This utility model discloses a conveyor line for cigarette storage. Cigarette cartons filled with cigarette sticks are conveyed by a first conveyor roller into a first inclined roller. Under the action of the first inclined roller, the cartons are conveyed at an angle to one side. With the protection of the anti-collision frame and guide wheels of the guide assembly, the cartons are neatly conveyed to one side. After passing the first inclined roller, the cartons enter a second inclined roller. Because the inclination direction of the second inclined roller is opposite to that of the first, the cartons are conveyed towards the center position. Although it cannot guarantee the exact center position, it ensures that each carton is in a straight line, maintaining consistency so that the subsequent palletizing robot can accurately grasp the cartons and reduce the occurrence of malfunctions. When the cigarette box flows to the second conveyor roller, the two rotating rods of the two blocking devices near the second inclined roller are pulled outward by the electric push rod, opening the two rotating rods to allow one cigarette box to pass through before closing them, so that the cigarette box stays inside the blocking device, waiting for the palletizing robot to grab the front cigarette box. Then, the two rotating rods of the rear end are pulled outward by the electric push rod, opening the rotating rods and allowing the cigarette box to flow to the bottom of the palletizing robot, waiting to be grabbed. This control structure ensures that only one cigarette box reaches the bottom of the palletizing robot at a time, thus avoiding the cigarette boxes from being squeezed together, facilitating grabbing, reducing the occurrence of failures, and featuring ease of use and wide applicability.

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0018] See Figure 1-3 As shown, this utility model discloses a conveyor line for cigarette storage, including a conveyor support frame 1. One end of the conveyor support frame 1 is provided with multiple first conveyor rollers 4. Multiple forward-inclined first inclined rollers 5 are provided on the conveyor support frame 1 at the front end of the first conveyor rollers 4. Multiple backward-inclined second inclined rollers 7 are provided on the conveyor support frame 1 at the front end of the first inclined rollers 5. A second conveyor roller 8 is provided on the conveyor support frame 1 at the front end of the second inclined rollers 7. Both sides of the second conveyor rollers 8 are provided with blocking devices 3 for separating cigarette boxes. A guide assembly 2 is provided on one side above the first inclined rollers 5. Cigarette boxes filled with cigarettes enter the first inclined rollers 5 under the conveying of the first conveyor rollers 4. Under the action of the first inclined rollers 5, the cigarette boxes are conveyed at an angle to one side. With the obstruction of the anti-collision frame 21 and guide wheel 22 of the guide assembly 2, they are neatly conveyed to one side. After passing the first inclined rollers 5, the cigarette boxes enter the second inclined rollers 7. Because the inclination direction of the second inclined rollers 7 is different from that of the first inclined rollers 8... Conversely, roller 5 guides the cigarette boxes towards the center position under the conveying of the second inclined roller 7. While it cannot guarantee the exact center position, it ensures that each cigarette box is in a straight line, maintaining consistency so that the subsequent palletizing robot can accurately grasp the cigarette boxes and reduce the occurrence of failures. When the cigarette box flows to the second conveying roller 8, the two rotating rods 31 of the two side blocking devices 3 near the second inclined roller 7 are pulled outward by the electric push rod 34, causing the two rotating rods 31 to open, allowing one cigarette box to pass through before closing, so that the cigarette box stays inside the blocking device 3, waiting for the palletizing robot to grasp the front cigarette box. Then, the two rotating rods 31 of the rear end are pulled outward by the electric push rod 34, opening the rotating rods 31, and the cigarette box flows to the bottom of the palletizing robot, waiting to be grasped. This control structure ensures that only one cigarette box reaches the bottom of the palletizing robot at a time, thus avoiding the cigarette boxes being squeezed together, facilitating grasping, and reducing the occurrence of failures.

[0019] Specifically, transition rollers 6 are provided on both sides of the first inclined roller 5 and the second inclined roller 7 to play an auxiliary role, so that the transition of the cigarette box is smoother and the flow is smoother when it passes through the first inclined roller 5 and the second inclined roller 7.

[0020] Preferably, each of the conveyor support frames 1 on one side of the transition roller 6 is equipped with a photoelectric sensor 10. The photoelectric sensor 10 is electrically connected to an external PLC controller. When the cigarette box gets stuck at the transition roller 6, the photoelectric sensor 10 transmits a signal to the PLC controller. The PLC controller determines whether there is a blockage based on the dwell time. If a blockage occurs, the PLC controller controls the motor driving the roller to stop working.

[0021] Furthermore, the barrier device 3 includes a mounting base 32, an electric push rod 34, and two rotating rods 31. The mounting base 32 is mounted on the conveyor support frame 1 via a support plate 11. One end of each of the two rotating rods 31 is rotatably mounted on the mounting base 32 via a rotating shaft 33. Electric push rods 34 are provided on both sides of the mounting base 32. The output end of the electric push rod 34 is rotatably connected to the middle position of the rotating rod 31. When the cigarette box flows to the second conveyor roller 8, the two rotating rods 31 of the barrier device 3 on both sides near the second inclined roller 7 are pulled outward under the action of the electric push rod 34, so that the two rotating rods 31 open, allowing a cigarette box to pass through and then closing, so that the cigarette box stays in the barrier device 3, waiting for the palletizing robot to grab the cigarette box at the front end. Then, the two rotating rods 31 at the rear end are pulled outward under the action of the electric push rod 34, opening the rotating rods 31, and the cigarette box flows to the bottom of the palletizing robot, waiting to be grabbed, thus avoiding congestion of the cigarette box.

[0022] Furthermore, the rotating rod 31 is provided with multiple linearly arranged rotating wheels 9. When the tobacco box touches the rotating wheels 9, it makes sliding contact to prevent the rotating rod 31 from damaging the tobacco box.

[0023] Furthermore, the guide assembly 2 includes a crash barrier 21 and multiple guide wheels 22. The crash barrier 21 is installed on the conveying support frame 1 on one side of the first inclined roller 5. The multiple guide wheels 22 are arranged linearly on the crash barrier 21. Under the obstruction of the crash barrier 21 and the guide wheels 22 of the guide assembly 2, the conveying is neatly arranged on one side. The guide wheels 22 play a guiding role, making the sliding smoother.

[0024] In this embodiment, a cigarette loading conveyor line operates as follows: Cigarette cartons filled with cigarette sticks are conveyed by the first conveying roller 4 into the first inclined roller 5. Under the action of the first inclined roller 5, the cartons are tilted to one side and conveyed neatly to one side by the anti-collision frame 21 and guide wheels 22 of the guide assembly 2. After passing the first inclined roller 5, the cartons enter the second inclined roller 7. Because the inclination direction of the second inclined roller 7 is opposite to that of the first inclined roller 5, the cartons are conveyed towards the center position under the transport of the second inclined roller 7. Although it cannot guarantee the exact center position, it ensures that each carton is in a straight line, maintaining consistency so that the subsequent palletizing robot can accurately grasp the cigarette cartons. To reduce the occurrence of malfunctions, when the cigarette box flows to the second conveyor roller 8, the two rotating rods 31 of the two blocking devices 3 near the second inclined roller 7 are pulled outwards by the electric push rod 34, causing the two rotating rods 31 to open, allowing one cigarette box to pass through before closing, so that the cigarette box stays inside the blocking device 3, waiting for the palletizing robot to grab the front cigarette box. Then, the two rotating rods 31 of the rear end are pulled outwards by the electric push rod 34, opening the rotating rods 31, and the cigarette box flows to the bottom of the palletizing robot, waiting to be grabbed. With this control structure, only one cigarette box reaches the bottom of the palletizing robot at a time, thus avoiding the cigarette boxes from being squeezed together, facilitating grabbing, and reducing the occurrence of malfunctions. This utility model provides a cigarette storage conveyor line that automatically and neatly arranges cigarette boxes, making it easier for the palletizing robot to grab and reducing the occurrence of malfunctions.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model, and these will not affect the implementation effect of the present utility model or the practicality of the patent.
