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 there are vacancies on the cigarette packaging production line due to the operation of removing unqualified cigarette packs, technicians need to add the cigarette packs at the low position to the cigarette pack conveying device at the high 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 efficiency of replenishment; 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 repairer (application number: 201921002319.2) for the cigarette packaging industry. The cigarette pack repairer includes a bracket and a conveyor belt horizontally arranged on the bracket. A material guide track is provided at the end of the conveyor belt. The material 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 replenishing device cannot transport the 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 material guide track. Since the cigarette packs are rectangular, this arc-shaped material 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 material guide track is appropriately increased to avoid the negative effect of squeezing the cigarette packs, the cigarette packs are prone to tilt due to the gap between them and the material guide track, thereby blocking the material guide track and affecting the transportation of the cigarette packs.

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 flipping the cigarette pack by 90 degrees, so that the cigarette pack is in a sideways posture when it reaches the starting position of the 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.

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 flipping the cigarette pack by 90 degrees, so that the cigarette pack is in a sideways posture when it reaches the starting position of the 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.

[0022] Furthermore, in all steps, the third sensor detects in real time whether the number of remaining cigarette packs in the storage bin is zero; If the number of remaining cigarette packs in the storage bin is zero, the first control unit controls the second pack pushing assembly to stop, the second control unit controls the lifting device to stop, the third pushing unit controls the first pack pushing assembly to stop, and the cigarette pack conveying is suspended, waiting for workers to replenish cigarette packs in the storage bin; 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 a control command.

[0023] 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.

[0024] 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 out a first type of early warning signal, the first control unit controls the second package pushing assembly 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.

The first control unit controls the second pack pushing assembly to shut down after receiving the fourth type of early warning signal, and the second control unit controls the lifting device to shut down after receiving the fourth type of early warning signal. The third control unit controls the first pack pushing assembly to shut down after receiving the fourth type of early warning signal, waiting for workers to debug and repair the lifting device.

[0028] Furthermore, the conveying mechanism includes two relatively 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 connected to the same driving motor, and the two vertical conveyor belts are driven by the same driving motor to operate synchronously.

[0029] Furthermore, the object-carrying assembly comprises two bearing bars, which are respectively fixedly arranged on two vertical conveyor belts, and when the two vertical conveyor belts are synchronously operated, the two bearing bars are always aligned with each other to jointly support the cigarette packs.

[0030] 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 reciprocately push the cigarette pack located at the discharge port of the lifting device.

[0031] 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 presses against the toggle teeth and rotates around the toggle roller with the toggle teeth to flip itself from a lying position to an upright position.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Beneficial effects of the present invention: A cigarette pack lifting and conveying device of the present invention realizes the purpose of vertically lifting and transporting cigarette packs by setting up 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.

[0036] 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 narrow and irregular installation space.

[0037] Since the cigarette package is in the shape of a relatively small cuboid, 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; in this regard, the present application further provides a storage bin, a second package pushing assembly, and a flipping assembly. In the process of the second package pushing assembly pushing the cigarette package at the lower end opening of the storage bin to the feed port of the lifting device, the pushed cigarette package also passes through the flipping assembly laterally, and the second package pushing assembly also cooperates with the flipping assembly so that when the cigarette package is pushed to move laterally through the flipping assembly, the flipping assembly rotates synchronously to The cigarette pack is flipped 90°, thereby changing from a flat lying posture with the large surface facing upward to an upright posture with the large surface facing the side, and the cigarette pack is further lifted by a lifting device and transported to its discharge port in the upright posture; thereafter, the first pack pushing component corresponds to when pushing 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 over-squeezed and deformed by the first pack pushing component to a certain extent.

[0038] In addition, since the cigarette pack contacts the carrier assembly with its small surface, the contact area between the cigarette pack and the carrier assembly is also reduced, which further reduces the resistance to pushing the cigarette pack. Therefore, the cigarette pack can enter the transfer rail faster when being pushed by the first pack pushing assembly, and the cigarette pack conveying speed can be further improved.

[0039] 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 staff's workload and further reducing production costs, improving quality and efficiency.

DETAILED DESCRIPTION

[0042] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0043] See also Figure 1A cigarette pack lifting and conveying device according to a specific embodiment of the present invention comprises a lifting device 1 and a first pack pushing assembly 2. The lifting device 1 comprises a conveying mechanism 11 and a carrier assembly 12. The conveying mechanism 11 is vertically arranged. A plurality of carrier assemblies 12 are arranged on the conveying mechanism 11. The carrier assemblies 12 are used to carry cigarette packs. The first pack pushing assembly 2 is arranged at the discharge port of the lifting device 1. The first pack pushing assembly 2 is used to push the cigarette packs on the carrier assembly 12 from the discharge port of the lifting device 1 into the cigarette pack packaging production line.

[0044] Specifically, the conveying mechanism 11 includes two vertical conveyor belts arranged opposite to each other, and two groups of pulley assemblies respectively used to drive each of the vertical conveyor belts to operate; the two groups of pulley assemblies are vertically arranged on a vertical bracket, and the two vertical conveyor belts are also vertically arranged on the vertical bracket accordingly.

[0045] Correspondingly, multiple bearing bars are evenly spaced on the two vertical conveyor belts, and the multiple bearing bars on the two vertical conveyor belts are opposite to each other to form multiple carrying components 12. When the bearing bars between the two vertical conveyor belts are driven to move from bottom to top, a cigarette pack can be supported by two opposite and mutually parallel bearing bars on the two vertical conveyor belts at the same time, and lifted and transported to the upper end of the vertical conveyor belts by the two bearing bars; when the cigarette pack is transported to the upper end of the lifting device 1 and transferred to the transfer device 6, the two bearing bars of a carrying component 12 can be separated from each other and moved to the back-to-back outer positions of the two vertical conveyor belts and moved downwards, until the two return to the lower ends of the opposite inner positions of the two vertical conveyor belts again, so as to support and transport the cigarette pack upwards again.

[0046] In addition, in this embodiment, the pulleys at the lower ends of the two pulley groups are rotatably mounted on a vertically movable adjustment block, and the two adjustment blocks are correspondingly and 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.

[0047] Please note: Please refer to Figure 1 In order to further limit the cigarette packs and prevent them from falling off 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 off the carrier assembly 12.

[0048] See also Figure 2 It should be noted that: in order to facilitate the understanding of the present invention by technicians in the field and examiners, the driving motors of the lifting device 1 and the transfer device 6 are not shown in the drawings of the present 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 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.

[0049] 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 pusher 23; the first transmission mechanism 22 includes an input connecting rod, a rotating connecting rod, an output connecting rod, and a limiting 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 rotating connecting rod, the right end of the rotating connecting rod is hinged to the left end of the output connecting rod, the output connecting rod is movably plugged and arranged on the limiting base, and the first pusher 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 pusher 23, and then by setting the first pusher 23 as a plate body, the first motor 21 can drive the first pusher 23 to repeatedly push the cigarette packs moved to the discharge port at the upper end of the lifting device 1 to the transfer device 6, and then the transfer device 6 transports and replenishes them to the cigarette pack packaging production line.

[0050] See also Figure 1 and Figure 2 The transfer device 6 and the first pack pushing assembly 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 assembly 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.

[0051] 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 is extended to the lower side of the discharge port of the lifting device 1. The transfer conveyor belt 61 is extended to the upper side of 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 fixedly arranged on the transfer conveyor belt 61. In this regard, when the transfer conveyor belt 61 is driven by an external driving device to run, the plurality of cigarette pushing assemblies 63 are driven to sequentially pass through the discharge port of the lifting device 1, so as to sequentially push the cigarette packs pushed out by the first pack pushing assembly 2 to the right end of the transfer guide rail 62, and allow the cigarette packs to enter the cigarette pack packaging production line one by one.

[0052] 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 arranged on the output rotating shaft of the driving motor, and the driving motor is also arranged horizontally on the right side of the transfer device 6.

[0053] For further information, see Figure 1 and Figure 4 In this embodiment, a base is provided on the left side of the vertical support, and a storage bin 4 is also provided on the base. A plurality 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 push 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 assembly 5 is also provided on the left side of the lower end of the storage bin 4, and a flip assembly 3 is also provided between the storage bin 4 and the lifting device 1.

[0054] Correspondingly, in the present 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 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 posture with the large surface facing upward to an upright posture with the large surface facing the side, and the cigarette pack is lifted and transported by the lifting device 1 in an upright posture, 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.

[0055] For details, please refer to Figure 4 The second package pushing assembly 5 includes a second motor 51, a second transmission mechanism 52, and a second pusher 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 rotating connecting rod, an output connecting rod, and a limiting base. One end of the input connecting rod is fixedly arranged 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 rotating connecting rod, the right end of the rotating connecting rod is hinged to the left end of the output connecting rod, the output connecting rod is movably inserted on the limiting base, and the second pusher 53 is fixedly installed on 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 pusher 53, and then by setting the second pusher 53 as a plate body, the second motor 51 can drive the second pusher 53 to repeatedly push the cigarette package from the lower end opening of the storage bin 4 to the feeding port at the lower end of the lifting device 1.

[0056] See also Figure 5 The flip 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, a portion of the body of each toggle tooth 32 extends to the bottom of the storage bin 4.

[0057] In this regard, the whole working principle of the cigarette pack being pushed into the flip assembly 3 from the lower end opening of the storage bin 4 and then flipped 90° by the flip assembly 3 and then entering the lifting device 1 specifically includes: Take the conveying and turning of a cigarette pack as an example; please refer to Figure 6 , the left end edge of the shifting tooth 32 on the upper left side of the flipping assembly 3 extends into the lower part of the storage bin 4, and the lower end edge of the second pushing member 53 is also provided with a flange for supporting the cigarette pack; 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 shifting tooth 32 on the upper left side, and then the second pushing member 53 pushes the cigarette pack to move to the right under the drive of the second motor 51. During this process, the flipping assembly 3 does not rotate until the right end of the cigarette pack abuts against the shifting tooth 32 on the upper right side of the flipping assembly 3; thereafter, the second pushing member 53 retreats to the left under the drive of the second motor 51, and the shifting roller 31 rotates 90° clockwise under the drive of the external driving device, and the cigarette pack that has abutted against the shifting tooth 32 on the upper right side is also turned 90° accordingly, and the cigarette pack becomes an upright posture, and the cigarette pack in the upright posture is just located at the feeding port at the lower end of the lifting device 1; finally, the conveying mechanism 11 lifts the cigarette pack in the upright posture upward for transportation.

[0058] 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 circular rotation of the stir roller 31 can achieve the work of mechanically adjusting the posture of the cigarette packs.

[0059] 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.

[0060] Anything not mentioned above is applicable to the prior art.
