Description

Technical Field

[0001] The present invention relates to the technical field of cigarette pack production equipment, and in particular to a cigarette pack lifting and conveying device. Background Art

[0002] During the cigarette packing process, when unqualified cigarette packs need to be discarded, gaps will be created; in addition, in order to reduce the floor space occupied by the cigarette pack production and packaging equipment, technicians will also set the cigarette pack conveying device between the cigarette pack production and packaging equipment above the cigarette pack production and packaging equipment to reduce the distance between each cigarette pack production and packaging equipment.

[0003] Affected by the above factors, when vacancies occur on the cigarette packaging production line due to the operation of rejecting unqualified cigarette packs, technicians need to add cigarette packs at a lower position to the cigarette pack conveying device at a higher position to fill the vacancies; however, in order to complete the replenishment work, technicians have to frequently walk between high and low positions, or bend over, which makes the technicians easily tired and affects the replenishment efficiency; moreover, at least one operator is required on each transportation line to complete the replenishment work, and the labor cost is also relatively high.

[0004] In this regard, a Chinese patent document discloses a cigarette pack refilling device (application number: 201921002319.2), which provides a cigarette pack refilling device for the cigarette packaging industry. The cigarette pack refilling device includes a bracket and a conveyor belt horizontally arranged on the bracket. The end of the conveyor belt is provided with a guide track. The guide track includes a feed end and a discharge end. The feed end is tilted downward, and the outlet of the discharge end is downward. It has the advantages of being able to flip the cigarette pack at a certain angle and having a simple structure.

[0005] However, the cigarette pack refilling device cannot transport cigarette packs at a low position to a high position.

[0006] In addition, the cigarette packs of the cigarette pack replenisher enter the next conveying device through an arc-shaped guide track. Since the cigarette packs are rectangular, this arc-shaped guide track not only allows the cigarette packs to flip 90 degrees, but also squeezes the cigarette packs, causing them to deform and affecting the appearance quality of the cigarette packs. In addition, if the channel size of the guide track is appropriately increased to avoid the negative effect of squeezing the cigarette packs, the cigarette packs are likely to tilt due to the gap between them and the guide track, thereby blocking the guide track and affecting the transportation of the cigarette packs.

If the first image acquisition unit detects that there is no cigarette pack at the position to be flipped, the fourth control unit controls the flip assembly to stop.

[0033] A position to be flipped is provided on the moving path along which the cigarette pack is pushed toward the starting position for lifting and conveying. The first image acquisition unit is used to detect whether there is a cigarette pack at the position to be flipped. If the first image acquisition unit detects that there is a cigarette pack at the position to be flipped, the fourth control unit controls the flip assembly to start and flip the cigarette pack 90 degrees, so that the cigarette pack is in a sideways position when it reaches the starting position for lifting and conveying. If the first image acquisition unit detects that there is no cigarette pack at the position to be flipped, the fourth control unit controls the flip assembly to stop.

[0037] If the number of remaining cigarette packs in the storage bin is not zero, the first control unit, the second control unit and the third control unit do not issue any control command.

[0038] Furthermore, the cigarette packet conveying device also includes an early warning device, which is connected to the first sensor, the second sensor, the third sensor, the first image acquisition unit, the second image acquisition unit, the first control unit, the second control unit, the third control unit, and the fourth control unit.

[0039] Furthermore, the number of times the cigarette packs appear at the starting position of the lifting and conveying is counted, and a threshold value of the number of times the cigarette packs appear at the starting position of the lifting and conveying is set; when the counted number of times the cigarette packs appear at the starting position of the lifting and conveying increases to the set threshold value of the number of times the cigarette packs appear at the starting position of the lifting and conveying, the early warning device sends a first type of early warning signal, the first control unit controls the second pack pushing component to shut down according to the received first type of early warning signal, the second control unit does not recognize the first type of early warning signal, and the third control unit also does not recognize the first type of early warning signal.

[0041] Furthermore, if the first sensor detects that there is a cigarette pack at the lifting and conveying starting position, the first image acquisition unit works to detect whether the cigarette pack at the lifting and conveying starting position is in a sideways posture and whether there is any deformation;

[0042] If the cigarette pack is not in a sideways posture and / or is deformed, the first image acquisition unit sends a detection failure signal to the early warning device, and the early warning device sends a third-type early warning signal. After receiving the third-type early warning signal, the first control unit controls the second pack pushing component to stop. After receiving the third-type early warning signal, the second control unit controls the lifting device to stop.

[0043] Furthermore, if the second sensor detects that there is a cigarette pack at the end position of the lifting and conveying, and the first pack pushing assembly is in the starting operation state, the second image acquisition unit works to detect whether the cigarette pack at the starting position of the lifting and conveying is deformed; if the cigarette pack is deformed, the second image acquisition unit sends a detection failure signal to the early warning device, and the early warning device sends a fourth type of early warning signal. After receiving the fourth type of early warning signal, the first control unit controls the second pack pushing assembly to stop, the second control unit controls the lifting device to stop after receiving the fourth type of early warning signal, and the third control unit controls the first pack pushing assembly to stop after receiving the fourth type of early warning signal, waiting for workers to debug and repair the lifting device.

[0045] Furthermore, the carrying assembly includes two supporting bars, which are fixedly arranged on two vertical conveyor belts respectively, and when the two vertical conveyor belts run synchronously, the two supporting bars are always aligned with each other to jointly support the cigarette packs.

[0046] Furthermore, the first pack pushing assembly includes a first motor, a first transmission mechanism, and a first pushing member. The first transmission mechanism is used to connect the first motor and the first pushing member. The first motor drives the first pushing member to perform linear reciprocating motion through the first transmission mechanism, thereby causing the first pushing member to reciprocate and push away the cigarette pack located at the discharge port of the lifting device.

[0047] Furthermore, the flipping assembly includes a toggle roller rotatably arranged at the feed port of the lifting device, and a plurality of toggle teeth arranged around the toggle roller. The cigarette pack is pressed against the toggle teeth and rotates around the toggle roller along with the toggle teeth to flip itself from a lying position to an upright position.

[0048] Furthermore, an opening is provided at the upper end of the storage bin, and multiple cigarette packs are stacked and stored in the storage bin from the opening above the storage bin; an opening is also provided at the lower end of the storage bin, and the second pack pushing assembly is used to push the cigarette packs from the lower end opening of the storage bin to the feed port of the lifting device.

[0049] Furthermore, the second pack pushing assembly includes a second motor, a second transmission mechanism, and a second pushing member. The second transmission mechanism is used to connect the second motor and the second pushing member. The second motor drives the second pushing member to perform linear reciprocating motion through the second transmission mechanism, so that the second pushing member mechanically pushes the cigarette pack located at the lower end opening of the storage bin to the feed port of the lifting device.

[0050] Furthermore, the transfer device includes a transfer conveyor belt, a transfer guide rail, and a cigarette pushing assembly. One end of the transfer guide rail extends to below the discharge port of the lifting device, and the transfer conveyor belt extends to above the discharge port of the lifting device. The transfer conveyor belt is provided with multiple cigarette pushing assemblies, and the cigarette pushing assemblies are used to push the cigarette packs to move on the transfer guide rail so that the cigarette packs enter the cigarette pack packaging production line from the other end of the transfer guide rail.

[0051] Beneficial effects of the present invention:

[0052] A cigarette pack lifting and conveying device of the present invention achieves the purpose of vertically lifting and transporting cigarette packs by providing an upright conveying mechanism and arranging multiple loading components on the conveying mechanism; at the same time, a first pack pushing component and a transfer device are installed on the upper part of the lifting device to meet the mechanized operation requirements of automatically conveying cigarette packs from a low place to a high place, actively pushing the cigarette packs from the upper end of the lifting device to the transfer device in an orderly manner, and transporting the cigarette packs to the cigarette pack packaging production line by the transfer device.

[0053] The orientation of the bag pushing assembly of the present invention is perpendicular to that of the transfer device, and the width of the lifting device is smaller, so it can adapt to a small and irregular installation space.

[0054] Since the cigarette pack is in the shape of a rectangular block with a relatively small thickness, it has two relatively large faces and four other small faces, and the area of ​​one large face is much larger than the area of ​​the other four small faces; for this purpose, the present application further provides a storage bin, a second pack pushing assembly, and a flipping assembly. In the process of the second pack pushing assembly pushing the cigarette pack at the lower end opening of the storage bin to the feed port of the lifting device, the pushed cigarette pack also passes through the flipping assembly laterally, and the second pack pushing assembly also cooperates with the flipping assembly so that when the cigarette pack is pushed to move laterally through the flipping assembly, the flipping assembly rotates synchronously to The cigarette pack is flipped 90°, thereby changing the cigarette pack from a flat lying position with the large surface facing upward to an upright position with the large surface facing sideways, and the cigarette pack is further lifted by the lifting device in the upright position and transported to its discharge port; thereafter, the first pack pushing component pushes the cigarette pack at the discharge port of the lifting device onto the transfer device, and the first pack pushing component contacts the large surface of the cigarette pack. The area of ​​the large surface is larger than that of the small surface, and the pressure exerted by the first pack pushing component on the large surface is smaller. Therefore, it can reduce the risk of the cigarette pack being excessively squeezed and deformed by the first pack pushing component to a certain extent.

[0055] In addition, since the cigarette pack contacts the carrier component with its small surface, the contact area between the cigarette pack and the carrier component is also reduced, which further reduces the resistance to pushing the cigarette pack. Therefore, the cigarette pack can enter the transfer guide rail faster when being pushed by the first pack pushing component, and the cigarette pack conveying speed can be further improved.

[0056] In addition, since the second pack pushing component can automatically and orderly transfer the cigarette packs in the storage bin to the lifting device, the staff only needs to regularly replenish a specific number of cigarette packs to the storage bin instead of standing by the lifting device and putting the cigarette packs in one by one, thereby reducing the workload of the staff, further reducing production costs, and improving quality and efficiency.

[0071] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0072] See also Figure 1 A cigarette pack lifting and conveying device according to a specific embodiment of the present invention includes a lifting device 1 and a first pack pushing component 2. The lifting device 1 includes a conveying mechanism 11 and a carrier component 12. The conveying mechanism 11 is vertically arranged, and a plurality of carrier components 12 are arranged on the conveying mechanism 11. The carrier components 12 are used to carry cigarette packs; the first pack pushing component 2 is arranged at the discharge port of the lifting device 1, and the first pack pushing component 2 is used to push the cigarette packs on the carrier component 12 from the discharge port of the lifting device 1 into the cigarette pack packaging production line.

[0073] Specifically, the conveying mechanism 11 includes two oppositely arranged vertical conveyor belts, and two sets of pulley groups respectively used to drive each of the vertical conveyor belts to operate; the two sets of pulley groups are vertically arranged on a vertical bracket, and the two vertical conveyor belts are also vertically arranged on the vertical bracket.

[0074] Correspondingly, multiple supporting bars are evenly spaced on both vertical conveyor belts, and the multiple supporting bars on the two vertical conveyor belts are arranged in pairs to form multiple corresponding carrier assemblies 12. When the supporting bars between the two vertical conveyor belts are driven to move upward from bottom to top, a cigarette pack can be simultaneously supported by two opposing and mutually intersecting supporting bars on the two vertical conveyor belts, and lifted and transported upward by these two supporting bars to the upper end position of the vertical conveyor belts; after the cigarette pack is transported to the upper end position of the lifting device 1 and transferred to the transfer device 6, the two supporting bars of a carrier assembly 12 can separate from each other and move to the outer positions of the two vertical conveyor belts facing each other and move downward until they return to the lower ends of the opposing inner positions of the two vertical conveyor belts to once again support and transport the cigarette pack upward.

[0075] In addition, in this embodiment, the pulleys at the lower ends of the two pulley groups are each rotatably mounted on a vertically movable adjustment block, and the two adjustment blocks are correspondingly movably mounted on the vertical bracket. The technician can adjust the tension of the vertical conveyor belt by adjusting the vertical position of the adjustment block, so that the two vertical conveyor belts are always kept in a tensioned state, ensuring that the lifting device 1 can operate normally.

[0076] Please note: Please refer to Figure 1 In order to further limit the cigarette packs and prevent them from falling from the carrier assembly 12, limiting baffles can be set on both sides of the two vertical conveyor belts along the axial direction of the pulley. The limiting baffles on both sides cooperate with each other to further limit the cigarette packs in the horizontal direction to prevent them from falling from the carrier assembly 12.

[0077] See also Figure 2 It should be noted that: in order to facilitate the understanding of this solution by those skilled in the art and examiners, the driving motors of the lifting device 1 and the transfer device 6 are not drawn in the drawings of this application. Here is a separate explanation: Figure 1 Taking the shown orientation as an example, the driving motor of the lifting device 1 is arranged on the right side of the upper end of the lifting device 1, and the motor output shaft of the driving motor of the lifting device 1 passes through the gap of the transfer device 6 to extend to the right side of the two upper end side by side pulleys, and is connected to the two upper end side by side pulleys at the same time through the gear transmission mechanism. The specific structural form of the gear transmission mechanism can refer to the existing technology to drive the two pulleys to rotate synchronously and in opposite directions to drive the entire lifting device 1.

[0078] See also Figures 1 to 3 , the first package pushing assembly 2 is arranged on the left side of the upper end of the lifting device 1; the first package pushing assembly 2 includes a first motor 21, a first transmission mechanism 22, and a first pushing member 23; the first transmission mechanism 22 includes an input connecting rod, a rotary connecting rod, an output connecting rod, and a limit base, one end of the input connecting rod is fixedly arranged on the output rotating shaft of the first motor 21, the other end of the input connecting rod is hinged to the left end of the rotary connecting rod, the right end of the rotary connecting rod is hinged to the left end of the output connecting rod, the output connecting rod is movably plugged into the limit base, and the first pushing member 23 is fixedly installed on the right end of the output connecting rod; in this regard, when the first motor 21 is working, the first transmission mechanism 22 converts the rotational motion of the output rotating shaft of the first motor 21 into a reciprocating linear movement of the first pushing member 23, and then by setting the first pushing member 23 as a plate body, the first motor 21 can drive the first pushing member 23 to repeatedly push the cigarette packs moved to the discharge port at the upper end of the lifting device 1 onto the transfer device 6, and then the transfer device 6 transports and replenishes them to the cigarette pack packaging production line.

[0079] See also Figure 1 and Figure 2 The transfer device 6 and the first pack pushing component 2 are relatively arranged on both sides of the upper end of the lifting device 1, and the discharge port of the lifting device 1 faces the transfer device 6. The first pack pushing component 2 is used to push the cigarette packs from the discharge port of the lifting device 1 into the transfer device 6. The transfer device 6 is used to transfer the lifted cigarette packs to the cigarette pack packaging production line.

[0080] The transfer device 6 includes a transfer conveyor belt 61, a transfer guide rail 62, and a cigarette pushing assembly 63. One end of the transfer guide rail 62 extends below the discharge port of the lifting device 1, and the transfer conveyor belt 61 extends above the discharge port of the lifting device 1. The transfer conveyor belt 61 is provided with a plurality of cigarette pushing assemblies 63, which are push blocks fixed to the transfer conveyor belt 61. When the transfer conveyor belt 61 is driven by an external drive device, the plurality of cigarette pushing assemblies 63 are driven to sequentially pass through the discharge port of the lifting device 1, thereby pushing the cigarette packs pushed out by the first pack pushing assembly 2 one by one to the right end of the transfer guide rail 62, and allowing the cigarette packs to enter the cigarette pack packaging production line one by one.

[0081] It should be noted that the external driving device mentioned here can be understood as another driving motor, and the pulley of the transfer conveyor belt 61 is directly set on the output rotating shaft of the driving motor, and the driving motor is also horizontally arranged on the right side of the transfer device 6.

[0082] Further, see Figure 1 and Figure 4 In this embodiment, a base is provided on the left side of the vertical bracket, and a storage bin 4 is also provided on the base. A number of cigarette packs are vertically stacked and stored in the storage bin 4. An opening is provided at the upper end of the storage bin 4 for technicians to top up and replenish cigarette packs into the storage bin 4; an opening is also provided at the lower end of the storage bin 4, and a second pack pushing component 5 is provided on the left side of the lower end of the storage bin 4, and a flip component 3 is provided between the storage bin 4 and the lifting device 1.

[0083] Correspondingly, in this embodiment, the second pack pushing assembly 5 is used to push the cigarette pack laterally out of the opening at the lower end of the storage bin 4, and allow the cigarette pack to pass through the flipping assembly 3 and then reach the feed port at the lower end of the lifting device 1. The flipping assembly 3 flips the cigarette pack 90° when the cigarette pack passes through, so that the cigarette pack changes from a lying position with the large surface facing upward to an upright position with the large surface facing the side, and the cigarette pack is lifted and transported by the lifting device 1 in an upright position, so that the first pack pushing assembly 2 can push the cigarette pack into the transfer device 6, and further reduce the risk of the cigarette pack being squeezed and deformed during transportation.

[0084] For details, please refer to Figure 4The second package pushing assembly 5 includes a second motor 51, a second transmission mechanism 52, and a second pushing member 53. The second transmission mechanism 52 has the same structure as the first transmission mechanism 22. The second transmission mechanism 52 also includes an input connecting rod, a rotary connecting rod, an output connecting rod, and a limit base. One end of the input connecting rod is fixedly set on the output rotating shaft of the second motor 51, the other end of the input connecting rod is hinged to the left end of the rotary connecting rod, the right end of the rotary connecting rod is hinged to the left end of the output connecting rod, the output connecting rod is movably plugged into the limit base, and the second pushing member 53 is fixedly installed at the right end of the output connecting rod; in this regard, when the second motor 51 is working, the second transmission mechanism 52 converts the rotational motion of the output rotating shaft of the second motor 51 into a reciprocating linear movement of the second pushing member 53, and then by setting the second pushing member 53 as a plate body, the second motor 51 can drive the second pushing member 53 to repeatedly push the cigarette package from the lower end opening of the storage bin 4 to the feed port at the lower end of the lifting device 1.

[0085] See also Figure 5 The flipping assembly 3 includes a toggle roller 31 rotatably arranged at the feed port of the lifting device 1, and a plurality of toggle teeth 32 arranged around the toggle roller 31. The plurality of toggle teeth 32 are evenly arranged on the rotating roller, and when the toggle roller 31 rotates, part of the body of each toggle tooth 32 extends to the bottom of the storage bin 4.

[0086] In this regard, the entire working principle of the cigarette pack being pushed into the flip assembly 3 from the lower end opening of the storage bin 4, flipped 90° by the flip assembly 3, and then entering the lifting device 1 specifically includes:

[0087] Take the conveying and turning of a cigarette pack as an example; please refer to Figure 6 When the second pushing member 53 is in the initial position on the left side of the storage bin 4, the cigarette pack naturally falls to a position supported by both the second pushing member 53 and the upper left tooth 32. Then, the second pushing member 53 pushes the cigarette pack to the right under the drive of the second motor 51. During this process, the turning assembly 3 does not rotate until the right end of the cigarette pack abuts the upper right tooth 32 of the turning assembly 3. Afterwards, the second pushing member 53 retreats to the left under the drive of the second motor 51, and the driving roller 31 rotates 90° clockwise under the drive of the external driving device. The cigarette pack that has abutted the upper right tooth 32 is also turned 90° accordingly, and the cigarette pack becomes an upright position, and the cigarette pack in the upright position is just located at the feed port at the lower end of the lifting device 1. Finally, the conveying mechanism 11 lifts the cigarette pack in the upright position upward for transportation.

[0088] In this embodiment, the number of teeth 32 on the stir roller 31 can be four or six, that is, every time the stir roller 31 rotates one circle, four or six cigarette packs will be flipped to an upright position and lifted and transported in turn by the lifting device 1; and the cyclic rotation of the stir roller 31 can realize the mechanical adjustment of the cigarette pack posture.

[0089] It should be noted that the external driving device mentioned here is a motor, which is not the same motor as the first motor 21 , the second motor 51 , and the two driving motors mentioned above.

[0090] Any matters not mentioned above are applicable to the prior art.
