Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production, in particular to a carton recycling device. Background Art

[0002] In cigarette processing, the tobacco leaves produced by the leaf threshing and redrying production line are measured, pre-pressed, re-weighed, packed into boxes with certain weights and specifications, and marked. The boxed shaped tobacco leaves will be transported to the silk production line for further processing. The first process of the silk production line is tobacco leaf unpacking. Its principle is to separate the shaped tobacco leaves from the packaging carton, so that they can enter the next process intact, and then process the carton and repeat the process. From unpacking to tobacco leaf separation, and then to the collection pile of cartons, it is an integrated process, which plays a very important role in ensuring the continuous and stable production of the production line.

[0003] CN107963468A discloses a packaging carton folding and stacking device, the transmission mechanism in the application includes: a frame, a conveyor belt installed on the frame, a push plate is arranged at the input end of the conveyor belt, the conveyor belt is a chain driven by a motor, the push plate is fixedly connected to the chain and moves with the chain, two parallel guide rails are arranged along the conveyor belt on the top surface of the frame, the push plate has a slide groove that slides with the guide rail, a pressure rod is arranged along one side of the conveying path of the conveyor belt, the pressure rod is arranged perpendicular to the transmission path, the pressure rod is driven by the pressure rod driving cylinder, and a second photoelectric detection sensor is arranged upstream of the pressure rod and close to the pressure rod. When the push plate in the above transmission mechanism is used to push the carton to move along the conveyor belt to the pallet of the next process, the folded carton will have an unstable center of gravity problem, so that the folded carton cannot reach the pallet smoothly, resulting in low carton recovery efficiency and high work intensity of operators, and is not suitable for the rhythm of modern production lines. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the existing shaped tobacco packaging carton recycling device is prone to unstable center of gravity, resulting in low recycling efficiency and high workload of operators. The utility model provides a carton recycling device, which can complete the recycling of cartons by using a receiving mechanism, a conveying mechanism and a distribution mechanism, and the push plate of the conveying mechanism is set as a vertical plane and a horizontal flange, and an auxiliary guide is added to assist in folding the carton, thereby increasing the stability of the folded carton moving along the conveying mechanism to the distribution mechanism, thereby improving the carton recycling efficiency and reducing the workload of operators.

[0005] In order to solve the above technical problems, the inventors explored and found that the main reason why the current carton recycling device causes the center of gravity of the carton to be unstable and easy to slip is: in the existing carton recycling, in order to ensure that the carton stacking plate under the apportionment mechanism can stack as many cartons as possible, the conveying mechanism will be tilted relative to the ground, and then the carton will be pushed along the conveying mechanism by the push plate installed on the conveying mechanism; when the carton is pushed to the top of the conveying mechanism (or reaches the support plate of the apportionment mechanism), the push plate will not be able to support the carton, which makes the carton prone to unstable center of gravity, and then the carton cannot reach the apportionment mechanism smoothly, resulting in low carton recycling efficiency and high work intensity for operators.

At the same time, the present application also provides a relatively symmetrical distribution plate, and the distribution plate can be relatively close to or away from each other along the width direction of the conveyor belt, so that the carton that falls on the distribution plate can fall smoothly into the next process, thereby improving the reliability of the carton recovery device.

[0035] 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.

[0036] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a carton recycling device, including a receiving mechanism 1, a conveying mechanism 2 and an allocating mechanism 3.

[0037] The receiving mechanism 1 is used to receive and open the carton and flip the carton onto the conveying mechanism 2.

[0038] The conveying mechanism 2 is used to convey the cartons to the distribution mechanism 3 arranged downstream in the transmission direction of the conveying mechanism 2. The conveying mechanism 2 includes a conveyor belt 21, a push plate 22, a pressure rod 23 and an auxiliary guide member 24. The push plate 22 is connected to the conveyor belt 21 and moves along the transmission direction of the conveying mechanism 2 with the conveyor belt 21. The pressure rod 23 and the auxiliary guide member 24 are respectively arranged on both sides of the conveying mechanism 2. The pressure rod 23 and the auxiliary guide member 24 are both used to fold the carton so that one end of the carton falls into the push plate 22.

[0039] The apportionment mechanism 3 is installed on a column 31, and the column 31 is used to support the height of the apportionment mechanism 3 to the output end of the conveying mechanism 2. The apportionment mechanism 3 includes two pallet assemblies 32, and the two pallet assemblies 32 are respectively installed on the two columns 31 and symmetrically arranged along the center lines of the two columns 31.

[0040] Specifically, each pallet assembly 32 includes a distribution plate 321, a limit rod 322, and a first driving unit 323. The distribution plate 321 is used to receive the cartons conveyed by the conveying mechanism 2. The first driving unit 323 is connected to the distribution plate 321. Each first driving unit 323 can drive each distribution plate 321 to be relatively close to or away from each other along the width direction of the conveyor belt 21. The limit rod 322 is arranged on the distribution plate 321 to prevent the folded cartons from shifting.

[0041] The applicant has fully considered the problems that arise when the carton recycling device recycles cartons. By using the receiving mechanism 1 to receive and flip the carton to the conveying mechanism 2, and then folding the carton through the pressure rod 23 and the auxiliary guide member 24 provided on the conveying mechanism 2, the carton can be completely folded into a "one" shape, so that one end of the carton falls completely into the push plate 22, increasing the stability of the push plate 22 supporting the carton, so that the carton can always keep the center of gravity stable when the conveying mechanism 2 is transported and smoothly transferred to the apportionment mechanism 3, thereby improving the efficiency of carton recycling and reducing the work intensity of the operator. At the same time, the present application also provides a relatively symmetrical apportionment plate 321, and the apportionment plate 321 can be relatively close to or away from the width direction of the conveyor belt 21, so that the carton falling on the apportionment plate 321 can fall smoothly into the next process, thereby improving the reliability of the carton recycling device. In addition, the limit rod 322 provided on the apportionment plate 321 can limit the carton from moving with the movement of the apportionment plate 321, thereby improving the stability and work efficiency of the carton recycling device.

[0042] Furthermore, if Figure 3As shown, the receiving mechanism 1 comprises:

[0043] Bottom plate 11;

[0044] A support frame 12 is provided on the bottom plate 11, and the carton is sleeved on the support frame 12 to limit the displacement of the carton;

[0045] The spreading device 13 is arranged on the support frame 12. The spreading device 13 includes a pair of symmetrically arranged spreading arms 131 and a second driving part 132. The pair of spreading arms 131 are hinged to the support frame 12. The second driving part 132 drives the spreading arms 131 to rotate in a vertical plane.

[0046] The turning assembly 14 is used to drive the bottom plate 11, the support frame 12 and the propping device 13 to turn over.

[0047] Specifically, a first photoelectric detection sensor 15 is provided on the bottom plate 11 for detecting whether the carton is in place in the receiving mechanism 1 .

[0048] In specific implementation, the push plate 22 is provided with a vertical plane and a horizontal flange, and the horizontal flange and the vertical plane are respectively used to push the carton to move before and after folding.

[0049] Specifically, firstly, the robot grasps the carton to be folded, and buckles the carton to be folded on the support frame 12. The carton falls under the action of gravity, and the two hinges in contact with the support frame 12 open. When the carton falls into place, the first photoelectric detection sensor 15 detects the carton signal and transmits it to the second drive unit 132 and the motor of the flip assembly 14. The second drive unit 132 drives the opening arm 131 to open and open the other pair of hinges. At the same time, the motor starts to drive the bottom plate 11, the support frame 12 and the opening device 13 to flip to the input end of the conveying mechanism 2. Subsequently, the conveyor belt 21 on the conveying mechanism 2 drives the push plate 22 to move so that the carton is separated from the receiving mechanism 1. When the carton is completely separated, the horizontal flange of the push plate 22 continues to drive the carton to be transported along the conveyor belt 21. When the carton is transferred to the bottom of the pressure rod 23, the conveyor belt 21 is suspended, and the pressure rod 23 is pressed down to flatten the carton. At this time, the carton near the auxiliary guide 24 is not completely flattened, so the auxiliary guide 24 is used to fold the carton for a second time, so that the carton is completely folded into a "one" shape and falls into a groove composed of a vertical plane and a horizontal flange. Then the conveyor belt 21 restarts and drives the push plate 22 and the carton to the output end of the conveying mechanism 2. Subsequently, the folded carton is transferred to the junction of the output end of the conveying mechanism 2 and the apportionment plate 321. Before the folded carton partially leaves the conveying mechanism 2, the carton will tilt toward the apportionment plate 321. At this time, the end of the carton that contacts the push plate 22 is pressed by the horizontal flange of the push plate 22, and the vertical plane of the push plate 22 continues to transfer the carton. The other end of the carton is received by the apportionment plate 321 in the folded state. Finally, the first driving unit 323 is used to drive the distribution plate 321 to open, and the carton falls to the next process. The distribution plate 321 is then driven by the first driving unit 323 to a folded state to wait for the next carton.

[0050] Furthermore, the conveying mechanism 2 further includes a slide rail 25 arranged along the conveying belt 21 , and the push plate 22 is provided with a slide groove 26 slidably connected to the slide rail 25 .

[0051] The carton recovery device of the present invention is provided with a slide rail 25 along the conveyor belt 21 and a slide groove 26 matched with the slide rail 25, so that the slide groove 26 can drive the push plate 22 to move along the transmission direction of the conveyor belt 21, so as to smoothly transmit the carton.

[0052] In some embodiments, the conveyor belt 21 may be a chain, and the push plate 22 is fixed on the chain and moves with the chain.

[0053] Furthermore, one end of the pressure rod 23 is connected to one side of the conveying mechanism 2, and a second photoelectric detection sensor 27 is provided at one end of the pressure rod 23. When the second photoelectric detection sensor 27 does not detect that a carton is in place, the pressure rod 23 is arranged perpendicular to the transmission direction of the conveying mechanism 2.

[0054] Further, refer to Figure 5One end of the auxiliary guide member 24 is connected to the other side of the conveying mechanism 2, and a third driving unit 28 is provided at one end of the auxiliary guide member 24. The third driving unit 28 drives the auxiliary guide member 24 to fold the carton.

[0055] The carton recovery device of the present invention can detect the carton transmitted by the conveying mechanism 2 through the second photoelectric detection sensor 27 arranged at one end of the pressure rod 23, and transmit the detection signal to the controller to drive the pressure rod 23 to flatten the carton, and then the controller controls the third driving part 28 to drive the auxiliary guide member 24, so that the pressure rod 23 and the auxiliary guide member 24 cooperate to flatten the carton, so that the flattened carton can fall into the groove formed by the vertical plane and the horizontal flange of the push plate 22, thereby ensuring the reliability of the conveying mechanism 2 in transporting the carton.

[0056] Specifically, Figure 4 As shown, the apportionment mechanism 3 also includes a slider 324 and a guide shaft 325. The slider 324 is arranged on the side of the apportionment plate 321 facing the ground. The guide shaft 325 passes through the slider 324 and both ends of the guide shaft 325 are fixedly connected to the column 31, so that the apportionment plate 321 can move along the width direction of the conveyor belt 21. When the apportionment plate 321 moves along the width direction of the conveyor belt 21, the apportionment plate 321 can move axially along the guide shaft 325 through the slider 324, so that the apportionment mechanism 3 completes the work of receiving the carton and dropping the carton vertically into the next process.

[0057] Furthermore, the carton recovery device also includes a stacking mechanism 4, which includes a carton stacking plate 41 arranged between the two columns 31 and a fourth driving unit (not shown in the figure), and the fourth driving unit can drive the carton stacking plate 41 to move up and down along the inner side of the two columns 31.

[0058] Specifically, the stacking mechanism 4 further includes a third photoelectric detector (not shown in the figure) for detecting the height of the cartons on the carton stacking plate 41 .

[0059] The carton recovery device of the present invention is provided with a stacking mechanism 4 below the distributing mechanism 3 to receive and stack the cartons dropped from the distributing plate 321, and a fourth driving unit is provided to drive the carton stacking plate 41 to move up and down along the column 31, so that the height of the carton stacking plate 41 can be adjusted according to the height of the cartons. In addition, a third photoelectric detector is provided to detect the height of the carton stacking, thereby improving the flexibility of the carton recovery device.
