Description

Technical Field

[0001] This invention belongs to the field of reusable cigarette addition in tobacco storage drums, specifically relating to a cigarette addition device for tobacco storage drums. Background Technology

[0002] Because the unloading machine in the cigarette rolling unit has been replaced with a cigarette storage drum, there is a problem that usable cigarettes cannot be reused normally. Operators can only manually put the sorted cigarettes into the feeding conveyor belt of the cigarette storage drum. This not only results in low cigarette addition efficiency, but also requires operators to handle cigarettes multiple times, which poses a series of risks such as cigarette wrinkling, tilting, and cigarette jamming, leading to significant hidden dangers in the quality of online products.

[0003] Publication number CN209305905U discloses a cigarette feeding device for a cigarette rolling machine. A fixed cigarette holder is installed above the cigarette conveyor of the cigarette rolling machine. The operator places reused cigarettes into the fixed cigarette holder, which then feeds the cigarettes onto the cigarette conveyor belt of the cigarette rolling machine. However, it has the following shortcomings:

[0004] 1. Since the cigarette storage tray is fixed, the operator needs to send the reworked cigarettes from the packaging machine site to the cigarette rolling machine site for processing, which makes it impossible to automate the cigarette adding process.

[0005] 2. When adding cigarettes using this device, the cigarettes rely entirely on their own weight, which causes the flipping plate to squeeze the cigarettes in the hopper when it moves, posing a potential quality hazard.

[0006] Existing technologies lack effective technical measures to address the aforementioned technical deficiencies and urgently need improvement. Summary of the Invention

[0007] In view of this, and considering the shortcomings of existing technologies, the purpose of this application is to provide a cigarette adding device for a cigarette storage drum, solving the problem of adding recycled cigarettes in cigarette rolling machines using cigarette storage drums. While ensuring the quality of recycled cigarettes, this patent can replace the traditional manual cigarette adding method with a fully automatic cigarette adding method, achieving automation of cigarette adding and improving the efficiency of recycling cigarette adding.

[0008] To achieve the above and other related objectives, this application provides a cigarette adding device for a cigarette storage drum, including a cigarette storage tray, a cigarette storage tray advancing and retreating device, a cigarette unloading device, a cigarette adding device, and a control system;

[0009] The bottom of the cigarette storage tray is equipped with an opening and closing door. The cigarette storage tray includes a cigarette tray compartment, a left movable base plate, a right movable base plate, a linear guide rail, a spring, a spring limiting cylinder, a cigarette baffle, and a frame. The cigarette tray compartment is used to fill cigarettes. The bottom of the cigarette tray compartment is equipped with a device consisting of a reset device for opening and closing the door, so that the bottom door of the cigarette tray compartment is open or closed. The open state is used for feeding. The reset device includes a protrusion for pushing and a spring element for resetting.

[0010] The smoke storage tray advance and retraction device is used for feeding, positioning, lifting and retracting the smoke storage tray. The smoke storage tray advance and retraction device includes a motor, smoke tray conveyor belt, blocking cylinder, positioning cylinder, feeding clamping cylinder, feeding cylinder, lifting rodless cylinder, and retraction clamping cylinder.

[0011] The cigarette storage trays containing cigarettes are transported by a cigarette tray conveyor belt. When they reach the waiting station, the cigarette tray conveyor belt stops, causing the cigarette storage tray to stop. The blocking cylinder opens, the feed clamping cylinder clamps the cigarette storage tray, and the feed cylinder drives the cigarette storage tray to the unloading position. The positioning cylinder activates to position the cigarette storage tray, the feed clamping cylinder releases the cigarette storage tray, the feed cylinder retracts, the blocking cylinder closes, and the cigarette tray conveyor belt rotates, causing the next cigarette storage tray to be transported to the waiting station.

[0012] The unloading cylinder is positioned between the waiting station and the unloading station;

[0013] When the cigarette storage tray containing cigarettes reaches the unloading position, the cigarette storage tray is limited and fixed by the lifting rodless cylinder; after the cigarettes are unloaded from the cigarette storage tray, the lifting rodless cylinder drives the cigarette storage tray to rise, the disengaging clamping cylinder clamps the cigarette storage tray, and the disengaging cylinder drives the cigarette storage tray into the disengagement position.

[0014] The cigarette unloading device includes an unloading cylinder, which is used to actuate a protrusion to open the door at the bottom of the cigarette tray. After the unloading cylinder releases the protrusion, the door at the bottom of the cigarette tray closes under the action of the elastic element. After the cigarette storage tray reaches the unloading position, the unloading cylinder is activated, the door at the bottom of the cigarette tray opens, and unloading is carried out.

[0015] After being unloaded from the cigarette storage pan, the cigarettes fall onto the lower conveyor belt. A cigarette distributor is installed in the vertical cigarette channel above the lower conveyor belt to ensure that the output of cigarettes at both ends of the cigarette storage pan is consistent. After moving on the conveyor belt, the cigarettes enter the transverse conveyor channel. Conveyor belts are installed at both the top and bottom of the transverse conveyor channel to ensure that the cigarettes are transported smoothly. A cigarette flow controller is installed at the end of the transverse conveyor belt. When the cigarette flow controller is lowered, the speed of the cigarette conveyor belt increases, and when the cigarette flow controller is raised, the speed of the cigarette conveyor belt decreases until it stops.

[0016] The control system includes a programmable controller, a servo controller, a motor, an HMI touch screen, a main contactor, intermediate relays, and detectors. The detectors are set up at the corresponding workstations to identify whether the cigarette storage tray is in the workstation, whether the lifting rodless cylinder has moved to the upper and lower limit positions, whether the empty cigarette storage tray has been withdrawn, whether there are cigarettes in the workstation, and whether the cigarettes on the transverse conveyor belt are full.

[0017] The technical solution provided in this application also has the following technical features:

[0018] Preferably, in one embodiment of this application, the cigarette unloading device includes an unloading cylinder, a lever, a guide column, an unloading cylinder connecting block, and a lever constraint groove. Two vertical guide columns are disposed on the unloading cylinder connecting block. A sliding pair is provided between the lever and the guide column. The lever is limited by the lever constraint groove. The unloading cylinder drives the guide column to move, and the guide column drives the lever to move. During the process of the lever moving to one side along the lever constraint groove, after the lever rises, it moves the protruding end of the movable base plate so that the left and right movable base plates move away from each other.

[0019] After unloading is completed, the unloading cylinder retracts. As the push block moves to one side along the push block constraint groove, it descends after moving. The push block and the protruding end of the movable base plate separate, and the left and right movable base plates approach each other under the action of the spring.

[0020] Preferably, in one embodiment of this application, the left movable base plate and the right movable base plate are installed at the bottom of the tobacco tray via linear guide rails, and a sliding pair is formed between the left movable base plate and the linear guide rails, and between the right movable base plate and the linear guide rails, so that the left movable base plate and the right movable base plate slide along the linear guide rails; the rear of the left movable base plate and the right movable base plate are provided with movable base plate protrusions, which are protrusions that extend out of the rear plate of the tobacco tray; the left movable base plate and the right movable base plate are in a closed state when they are close to each other and abut against each other, and in an open state when they are far apart from each other and do not contact each other.

[0021] Preferably, in one embodiment of this application, in one process segment, the left movable base plate and the right movable base plate are in a closed state under the action of springs; in another process segment, the cylinder pusher on the adding device pushes the protruding end of the movable base plate, and the protruding end of the movable base plate drives the left movable base plate and the right movable base plate to overcome the spring force and move away from each other, so that the left movable base plate and the right movable base plate are in an open state.

[0022] Preferably, in one embodiment of this application, positioning strips are provided on both sides of the transport channel of the smoke storage tray, and the positioning strips are used to constrain the smoke storage tray.

[0023] Preferably, in one embodiment of this application, grooves are provided above both sides of the smoke storage tray, and brackets for lifting rodless cylinders are used to insert into the grooves.

[0024] Preferably, in one embodiment of this application, the distance between the waiting station and the unloading station is greater than 50mm.

[0025] Preferably, in one embodiment of this application, the detector includes a smoke storage tray waiting position detector, a smoke storage tray unloading position detector, a lower position detector of the lifting cylinder, an upper position detector of the lifting cylinder, an empty smoke tray in place detector, a cigarette material level detector, and a cigarette flow monitor.

[0026] The smoke storage tray waiting position detector is a self-reflective photoelectric detector. When the presence of the smoke storage tray is detected, after a 3-second delay, the motor of the smoke storage tray conveyor belt stops, and at the same time, the feed clamping cylinder is activated to clamp the smoke storage tray.

[0027] The cigarette storage tray unloading position detector is a self-reflective photoelectric detector. When the presence of the cigarette storage tray is detected, there is a 2-second delay. If the cigarette level detector does not detect any cigarettes, the unloading cylinder will be activated, and the left and right movable bottom plates of the cigarette storage tray will open, allowing the cigarettes to be unloaded.

[0028] The lower position detector of the lifting cylinder is an inductive proximity switch. When the lifting rodless cylinder is detected to be in the lowest position and the smoke storage tray unloading position detector detects that it is empty, the blocking cylinder opens and the feeding cylinder moves to send the smoke storage tray forward.

[0029] The upper position detector of the lifting cylinder is an inductive proximity switch. When it detects that the lifting rodless cylinder is in the upper limit position, it disengages the clamping cylinder action. After a delay of 1.5 seconds, it disengages the cylinder action and moves the empty smoke storage tray to the exit position.

[0030] The empty smoke tray position detector is an inductive proximity switch. When the empty smoke tray is detected to be in position and the upper position detector of the lifting cylinder detects that it is empty, the exit clamping cylinder is released. After a delay of 1.5 seconds, the exit cylinder moves forward to wait for the next empty smoke tray.

[0031] The cigarette level detector is a through-beam photoelectric detector. When no cigarette is detected and the cigarette storage pan unloading position detector detects the cigarette pan, the unloading cylinder is activated to start unloading. When a cigarette is detected, the program module uses this signal as a servo drive action signal to control the cigarette conveyor belt to transport cigarettes. When no cigarette is detected again, the conveyor belt stops, the unloading cylinder retracts, and after a 2-second delay, the lifting rodless cylinder is activated.

[0032] The cigarette flow monitor consists of two proximity electronic switches; the program module uses the two proximity electronic switches to form three logic control relationships to achieve compensation speed control for reused cigarettes: high speed when completely unobstructed; low speed when the lower part is obstructed; and stops operating when completely obstructed.

[0033] The beneficial effects of this application are as follows:

[0034] After this application is put into use, operators will sort the recycled cigarettes at the packaging machine site and place them into the cigarette storage tray. Then, the full cigarette storage tray will be placed on the automatic cigarette adding device. By controlling the button, the automatic cigarette adding device can be started to complete the fully automatic addition of recycled cigarettes. This will minimize the operator's contact with the cigarettes, ensure the quality of the recycled cigarettes, greatly improve the efficiency of adding recycled cigarettes, and significantly reduce cigarette consumption.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0085] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0086] The technical solution of this application is to realize an automatic refilling device for reusable cigarettes under the condition that the cigarette storage roller is used in the cigarette rolling and packaging unit; the operator completes the sorting of reusable cigarettes at the packaging machine site and puts them into the cigarette storage tray, and then places the full cigarette storage tray on the automatic filling device, and starts the cigarette filling device by controlling the button to complete the fully automatic filling of reusable cigarettes.

[0087] The automatic cigarette adding device consists of four parts: a bottom-openable cigarette storage tray, an automatic feeding and unloading mechanism for the cigarette storage tray, a cigarette unloading device, a cigarette adding device, and a control system.

[0088] like Figure 1-7 A cigarette adding device for a cigarette storage drum includes a cigarette storage tray 20, a cigarette storage tray advancing and retreating device, a cigarette unloading device, a cigarette adding device, and a control system.

[0089] The bottom of the cigarette storage tray 20 is provided with an opening and closing door. The cigarette storage tray 20 includes a cigarette tray 27, a left movable bottom plate 21, a right movable bottom plate 22, a linear guide rail 23, a spring 24, a spring limiting cylinder, a cigarette baffle, and a frame. The cigarette tray 27 is used to fill cigarettes. The bottom of the cigarette tray 27 is provided with a device for opening and closing the door, which is composed of a reset device, so that the bottom door of the cigarette tray 27 is open or closed. The open state is used for feeding. The reset device includes a protrusion for pushing and a spring element for resetting.

[0090] The smoke storage tray advance and retreat device is used for the feeding, positioning, lifting and retraction of the smoke storage tray 20. The smoke storage tray advance and retreat device includes a motor, smoke tray conveyor belt 3, blocking cylinder 4, positioning cylinder 5, feeding clamping cylinder 6, feeding cylinder 7, lifting rodless cylinder 8, and retraction clamping cylinder 9.

[0091] The cigarette storage tray 20 containing cigarettes is transported by the cigarette tray conveyor belt 3. When it reaches the waiting station, the cigarette tray conveyor belt 3 stops, causing the cigarette storage tray 20 to stop. The blocking cylinder 4 opens, the feed clamping cylinder 6 clamps the cigarette storage tray 20, and the feed cylinder 7 drives the cigarette storage tray 20 to the unloading position. The positioning cylinder 5 is activated to position the cigarette storage tray 20. The feed clamping cylinder 6 releases the cigarette storage tray 20, the feed cylinder 7 retracts, the blocking cylinder 4 closes, and the cigarette tray conveyor belt 3 rotates, causing the next cigarette storage tray 20 to be transported to the waiting station.

[0092] The unloading cylinder is positioned between the waiting station and the unloading station;

[0093] When the cigarette storage tray 20 containing cigarettes reaches the unloading position, the cigarette storage tray 20 is limited and fixed by the lifting rodless cylinder 8; after the cigarette storage tray 20 is empty, the lifting rodless cylinder 8 drives the cigarette storage tray 20 to be lifted upward, the exit clamping cylinder 9 clamps the cigarette storage tray 20, and the exit cylinder 10 drives the cigarette storage tray 20 into the exit position.

[0094] The cigarette unloading device includes an unloading cylinder, which is used to push the protrusion to open the door at the bottom of the cigarette tray 27. After the unloading cylinder releases the protrusion, the door at the bottom of the cigarette tray 27 closes under the action of the elastic element. After the cigarette storage tray 20 reaches the unloading position, the unloading cylinder is activated, the door at the bottom of the cigarette tray 27 opens, and unloading is carried out.

[0095] After being unloaded from the cigarette storage pan 20, the cigarettes fall onto the lower conveyor belt 45. A cigarette distributor 42 is installed in the vertical cigarette channel above the lower conveyor belt 45 to ensure that the output of cigarettes at both ends of the cigarette storage pan 20 is consistent. After moving on the conveyor belt, the cigarettes enter the transverse conveyor channel. Conveyor belts are installed at both the top and bottom of the transverse conveyor channel to ensure that the cigarettes are transported smoothly in the transverse conveyor belt. A cigarette flow controller 47 is installed at the end of the transverse conveyor belt. When the cigarette flow controller 47 is lowered, the speed of the cigarette conveyor belt increases. When the cigarette flow controller 47 is raised, the speed of the cigarette conveyor belt decreases until it stops.

[0096] The control system includes a programmable controller, a servo controller, a motor 1, an HMI touch screen, a main contactor, an intermediate relay, and detectors. The detectors are set up at the corresponding workstations to identify whether the cigarette storage tray 20 is in the workstation, whether the lifting rodless cylinder 8 has moved to the upper limit position and the lower limit position, whether the empty cigarette storage tray 20 has been withdrawn into place, whether there are cigarettes in the workstation, and whether the cigarettes on the transverse conveyor belt are full.

[0097] When implementing this application, the key points are as follows:

[0098] The working principle or process of this application is as follows:

[0099] Specifically, in one embodiment of this application, the cigarette unloading device includes an unloading cylinder, a lever 34, a guide post 35, an unloading cylinder connecting block 36, and a lever constraint groove 37. Two vertical guide posts 35 are disposed on the unloading cylinder connecting block 36. A sliding pair is provided between the lever 34 and the guide post 35. The lever 34 is limited by the lever constraint groove 37. The unloading cylinder drives the guide post 35 to move, and the guide post 35 drives the lever 34 to move. During the process of the lever 34 moving to one side along the lever constraint groove 37, after the lever 34 rises, it moves the movable bottom plate protruding end 25 to move, so that the left movable bottom plate 21 and the right movable bottom plate 22 move away from each other.

[0100] After unloading is completed, the unloading cylinder retracts. As the push block 34 moves to one side along the push block constraint groove 37, the push block 34 moves and then descends. The push block 34 and the protruding end 25 of the movable base plate separate, and the left movable base plate 21 and the right movable base plate 22 approach each other under the action of the spring 24.

[0101] Specifically, in one embodiment of this application, the left movable base plate 21 and the right movable base plate 22 are installed at the bottom of the tobacco tray 27 via a linear guide rail 23, and a sliding pair is formed between the left movable base plate 21 and the linear guide rail 23, and between the right movable base plate 22 and the linear guide rail 23, so that the left movable base plate 21 and the right movable base plate 22 slide along the linear guide rail 23; the rear of the left movable base plate 21 and the right movable base plate 22 is provided with a movable base plate protrusion 25, which is a protrusion that extends out of the rear plate of the tobacco tray 27; the left movable base plate 21 and the right movable base plate 22 are in a closed state when they are close to each other and abut against each other, and in an open state when they are far apart from each other and do not contact each other.

[0102] Specifically, in one embodiment of this application, in one process segment, the left movable base plate 21 and the right movable base plate 22 are in a closed state under the action of the spring 24; in another process segment, the cylinder pusher on the adding device pushes the movable base plate protruding end 25, and the movable base plate protruding end 25 drives the left movable base plate 21 and the right movable base plate 22 to overcome the elastic force of the spring 24 and move away from each other, so that the left movable base plate 21 and the right movable base plate 22 are in an open state.

[0103] Specifically, in one embodiment of this application, positioning strips are provided on both sides of the transport channel of the smoke storage tray 20, and the positioning strips are used to constrain the smoke storage tray 20.

[0104] Specifically, in one embodiment of this application, grooves are provided on the upper sides of the smoke storage tray 20 to cooperate with the support of the lifting rodless cylinder 8, and the support is used to insert into the groove.

[0105] Specifically, in one embodiment of this application, the distance between the waiting station and the unloading station is greater than 50mm.

[0106] Specifically, in one embodiment of this application, the detector includes a smoke storage tray waiting position detector 51, a smoke storage tray unloading position detector 52, a lower position detector of the lifting cylinder 53, an upper position detector of the lifting cylinder 54, an empty smoke tray in place detector 55, a cigarette material level detector 56, and a cigarette flow monitor 57.

[0107] The smoke storage tray waiting position detector 51 is a self-reflective photoelectric detector. When the smoke storage tray 20 is detected, after a 3-second delay, the motor 1 of the conveyor belt of the smoke storage tray 20 stops, and at the same time, the feed clamping cylinder 6 is activated to clamp the smoke storage tray 20.

[0108] The cigarette storage pan unloading position detector 52 is a self-reflective photoelectric detector. When the presence of the cigarette storage pan 20 is detected, the unloading cylinder is activated after a 2-second delay and the cigarette level detector 56 does not detect any cigarettes. The left movable bottom plate 21 and the right movable bottom plate 22 of the cigarette storage pan 20 are opened, and the cigarettes are unloaded.

[0109] The lower position detector 53 of the lifting cylinder is an inductive proximity switch. When the lifting rodless cylinder 8 is detected to be in the lowest position and the smoke storage tray unloading position detector 52 detects that it is empty, the blocking cylinder 4 opens and the feeding cylinder 7 is activated to move the smoke storage tray 20 forward.

[0110] The upper position detector 54 of the lifting cylinder is an inductive proximity switch. When it detects that the lifting rodless cylinder 8 is in the upper limit position, the clamping cylinder 9 is activated. After a delay of 1.5 seconds, the retraction cylinder 10 is activated, and the empty smoke storage tray 20 is retracted to the retraction position.

[0111] The empty smoke tray position detector 55 is an inductive proximity switch. When the empty smoke tray 20 is identified as exiting into position and the upper position detector 54 of the lifting cylinder detects that it is empty, the exit clamping cylinder 9 is released. After a delay of 1.5 seconds, the exit cylinder 10 moves forward to wait for the next empty smoke tray 20.

[0112] The cigarette level detector 56 is a through-beam photoelectric detector. When no cigarette is detected and the cigarette storage pan unloading position detector 52 detects the cigarette pan, the unloading cylinder is activated to start unloading. When a cigarette is detected, the program module uses this signal as a servo drive action signal to control the cigarette conveyor belt to transport the cigarette. When no cigarette is detected again, the conveyor belt stops, the unloading cylinder retracts, and after a 2-second delay, the lifting rodless cylinder 8 is activated.

[0113] The cigarette flow monitor 57 consists of two proximity electronic switches; the program module uses the two proximity electronic switches to form three logic control relationships to achieve compensation speed control for the reused cigarettes; when all are unobstructed, it operates at high speed; when the lower part is obstructed, it operates at low speed; when all are obstructed, it stops operating.

[0114] like Figure 1 As shown, the bottom of the cigarette storage tray 20 can be opened and closed. The cigarette storage tray 20 is an independent bottom opening and closing type, which makes it convenient for operators to sort the reusable cigarettes on the packaging machine site, and has strong operability. When the cigarette storage tray 20 is filled with cigarettes, it can be placed directly on the cigarette adding device, minimizing the operator's contact with the cigarettes and ensuring the quality of the reusable cigarettes.

[0115] The cigarette storage tray 20 consists of a cigarette tray chamber 27, a left movable base plate 21, a right movable base plate 22, a linear guide rail 23, a spring 24, a spring limiting cylinder, a cigarette holder baffle, and a frame. The left movable base plate 21 and the right movable base plate 22 are mounted on the base plate of the cigarette tray chamber 27 via the linear guide rail 23, allowing for horizontal sliding of the left and right movable base plates 21 and 22. The rear of the left and right movable base plates 21 and 22 are provided with movable base plate protrusions 25, which are protrusions extending beyond the rear plate of the cigarette tray chamber 27. These protrusions allow for the handling of reused cigarettes by the operator. At this time, the left movable base plate 21 and the right movable base plate 22 are closed under the action of the spring 24, and the operator puts the cigarette into the cigarette tray 27. When the cigarette tray 27 needs to be unloaded, the cylinder pusher on the adding device pushes the protruding end 25 of the movable base plate at the rear of the cigarette tray 27, so that the movable base plate moves to both sides. At this time, the bottom of the cigarette tray 27 of the cigarette storage tray 20 is open, realizing the unloading of the cigarette tray. When the cigarette in the cigarette tray 27 is empty, the cylinder retracts, and the left movable base plate 21 and the right movable base plate 22 close again under the action of the spring 24.

[0116] like Figure 2The automatic feeding and retraction of the smoke storage tray 20, the smoke storage tray advance and retraction device, can realize the feeding of the fully loaded smoke storage tray 11, the positioning of the fully loaded smoke storage tray 11, and the lifting and retraction of the empty smoke storage tray 12;

[0117] A is the exit direction of the smoke storage tray 20, and B is the entry direction of the smoke storage tray 20.

[0118] The cigarette storage tray's forward and backward movement is controlled by a series of motors 1 and cylinders. The operator places the cigarette storage tray 20 containing cigarettes onto the cigarette storage tray conveyor belt 3. The conveyor belt 3 is controlled by a servo motor, which drives the cigarette storage tray 20 to move to the right. A blocking cylinder 4 is installed on the cigarette storage tray 20's path. When the cigarette storage tray 20 reaches the waiting position, the belt stops rotating, the blocking cylinder 4 opens, and the feed clamping cylinder 6 clamps the cigarette storage tray 20. Driven by the feed cylinder 7, the cigarette storage tray 20 is then conveyed... Upon reaching the unloading position, positioning cylinder 5 activates, positioning the smoke storage tray 20. At this time, feeding clamping cylinder 6 releases, feeding cylinder 7 retracts, blocking cylinder 4 closes again, and the smoke tray conveyor belt 3 rotates, transporting the next smoke storage tray 20 to the waiting position. There is a 65mm distance between the waiting position and the unloading position; this distance is the working position of the unloading cylinder. During the transport of the smoke storage tray 20, it moves under the constraint of positioning strips on both sides of the channel to prevent it from tipping over. When the fully loaded smoke storage tray 11 is transported to the unloading position, the slots on both sides of the smoke storage tray 20 insert into the brackets of lifting cylinder 8. After the fully loaded smoke storage tray 11 is emptied of smoke sticks, positioning cylinder 5 retracts, and the empty smoke storage tray 11 is lifted upwards by lifting cylinder 8. After being lifted into position, clamping cylinder 9 activates, and the empty smoke storage tray 12 enters the exit position under the action of exit cylinder 10, waiting for the operator to remove it.

[0119] like Figure 3 , 4During the cigarette unloading process, the cigarette unloading device is driven by a rodless cylinder, which can realize the opening and closing of the left movable base plate 21 and the right movable base plate 22 at the bottom of the cigarette storage tray 20. The cigarette unloading device is installed below the cigarette tray conveying channel. The lever 34 and the cylinder are both lower than the cigarette tray conveying belt, so as not to obstruct the conveying of the cigarette storage tray 20. When the cigarette storage tray 20 reaches the unloading position, the unloading cylinder is activated. Two vertical guide columns 35 are installed on the unloading cylinder connecting block 36. The lever 34 is installed on the two guide columns 35 through sliding bearings, which can realize the up and down movement of the lever 34. Driven by the material cylinder, the pusher block 34 moves to both sides. During the movement, the pusher block 34 moves upward under the action of the pusher block constraint groove 37, completing the movement while moving upward. The pusher block 34 pushes the movable bottom plate protruding end 25, and the movable plate achieves the opening action under the constraint of the guide groove 26 at the rear protruding end of the smoke tray. When the unloading is completed, the unloading cylinder retracts, and the pusher block 34 moves downward while moving. The upper part of the pusher block 34 is lower than the conveyor belt plane of the smoke storage tray 20, which facilitates the next smoke storage tray 20 to enter the unloading position. At this time, the left and right movable bottom plates 22 at the bottom of the empty smoke tray are closed under the action of the spring 24.

[0120] like Figure 5 The cigarette feeding device uses a belt conveyor to deliver cigarettes, and the conveyor belt is controlled by a servo motor.

[0121] After being unloaded from the cigarette storage tray 20, the cigarettes fall onto the lower conveyor belt 45, and move to the left under the drive of the lower conveyor belt 45. To ensure that the cigarettes fall evenly in the cigarette storage tray 20, a cigarette distributor 42 is installed in the vertical cigarette channel. The bottom of the cigarette distributor 42 is adjustable to ensure that the output of cigarettes at both ends of the cigarette storage tray 20 is consistent. After moving to the left on the conveyor belt, the cigarettes enter the transverse conveyor channel. The transverse conveyor channel is equipped with an upper conveyor belt 48 and a lower conveyor belt 45, respectively, to ensure that the cigarettes in the transverse conveyor belt are transported evenly. The cigarette delivery is smooth and there is no backlog. A cigarette flow controller 47 is installed at the leftmost end of the transverse conveyor belt. When the equipment is running at low speed, the amount of cigarettes replenished at the outlet decreases, and the cigarettes continue to be conveyed by the conveyor belt. The cigarette flow controller 47 is lifted, and the speed of the cigarette conveyor belt slows down until it stops. When the equipment is running at high speed, the amount of cigarettes replenished at the outlet increases, and the cigarette flow controller 47 drops. At this time, the speed of the cigarette conveyor belt increases, and the cigarettes are quickly replenished. This realizes that the cigarette adding device controls the replenishment of cigarette flow according to the speed of the equipment, ensuring the stable delivery of added cigarettes.

[0122] The lower conveyor belt 45 is equipped with a lower belt drive roller 46, and the upper conveyor belt 48 is equipped with an upper belt drive roller 49; the back plate 43 is a frame worktable for fixing and supporting various components.

[0123] like Figure 6 , 7The control system, in order to achieve effective control of the device, mainly consists of a programmable controller, a servo controller, a servo motor, an HMI touch screen, a proximity electronic switch, a photoelectric electronic switch, a main contactor, intermediate relays, etc.

[0124] The following devices are installed at their respective workstations: smoke storage pan waiting position detector 51, smoke storage pan unloading position detector 52, lifting cylinder lower position detector 53, lifting cylinder upper position detector 54, empty smoke pan in position detector 55, cigarette material level detector 56, and cigarette flow monitor 57.

[0125] Smoke storage tray waiting position detector 51: self-reflective photoelectric detection. When the presence of smoke storage tray 20 is detected, after a 3-second delay, the conveyor belt motor of smoke storage tray 20 stops, and at the same time, the feed clamping cylinder 6 is activated to clamp the smoke storage tray 20.

[0126] The cigarette storage tray unloading position detector 52 is a self-reflective photoelectric detector. When the presence of the cigarette storage tray is detected, there is a 2-second delay. If the cigarette level detector 56 does not detect any cigarettes, the unloading cylinder will be activated, the movable plate of the cigarette storage tray 20 will open, and the cigarettes will be unloaded.

[0127] Lifting cylinder lower position detector 53: Inductive proximity switch. When the lifting cylinder 8 is detected to be in the lowest position and the smoke storage tray unloading position detector 52 detects that it is empty, the blocking cylinder 4 opens and the feeding cylinder 7 is activated to move the smoke storage tray 20 forward.

[0128] Lifting cylinder upper position detector 54: Inductive proximity switch. When it detects that the lifting cylinder 8 is in the uppermost position, it will release the clamping cylinder 9 and after a delay of 1.5 seconds, it will release the cylinder 10 to move the empty smoke storage tray 20 to the release position.

[0129] Empty cigarette tray position detector 55: an inductive proximity switch. When it detects that the empty cigarette tray has exited into position and the upper position detector 54 of the lifting cylinder is empty, the exit clamping cylinder 9 is released. After a delay of 1.5 seconds, the exit cylinder 10 moves forward to wait for the next empty cigarette tray.

[0130] Cigarette level detector 56: Through-beam photoelectric detection. When no cigarette is detected and the cigarette storage tray unloading position detector 52 detects the cigarette tray, the unloading cylinder is activated to start unloading. When a cigarette is detected, the program module uses this signal as the enable signal for the servo motor to control the cigarette conveyor belt to transport cigarettes. When no cigarette is detected again, the conveyor belt stops, the unloading cylinder retracts, and after a 2-second delay, the lifting cylinder is activated.

[0131] Cigarette flow monitor 57: It consists of two proximity electronic switches; the program module uses the two proximity electronic switches to form three logic control relationships to realize the servo motor's compensation speed control for the reused cigarettes; when the switch is completely unobstructed, the servo motor runs at high speed; when the lower part is obstructed, the servo motor runs at low speed; when the switch is completely obstructed, the servo motor stops running.

[0132] In summary, the workflow of the cigarette adding device of this application is as follows: After the operator completes the sorting of recycled cigarettes at the packaging machine site, the cigarette storage tray 20 containing the recycled cigarettes is placed on the cigarette tray conveyor belt 3. The cigarette tray conveyor belt 3 is moved forward under the control of the servo motor. The cigarette tray stops moving after reaching the position of the blocking cylinder 4. At this time, the cigarette storage tray waits for the position detector 51 to detect the cigarette tray. After 3 seconds, the belt stops rotating. If the unloading position detector does not detect the cigarette tray and the lifting cylinder is in the lowest position, the feed clamping cylinder 6 clamps the cigarette tray, and at the same time the blocking cylinder 4 opens. After a delay of 2 seconds, the feed cylinder... Driven by cylinder 7, the cigarette storage tray 20 is transported to the unloading position. When the cigarette storage tray unloading position detector 52 detects the cigarette tray, there is a 2-second delay, and the positioning cylinder 5 is activated to position the cigarette storage tray 20. At this time, when the cigarette level detector 56 does not detect the presence of a cigarette, the unloading cylinder is activated, and the left and right movable plates of the cigarette storage tray 20 are opened to realize the unloading of the cigarette. At the same time, the feeding clamping cylinder 6 is released, the feeding cylinder 7 is retracted, the blocking cylinder 4 is closed again, the conveyor belt rotates, and the next cigarette storage tray 20 is transported to the waiting position. After the cigarette is unloaded, the cigarette conveyor belt rotates, and the cigarette is added to the cigarette conveyor belt of the cigarette storage drum. When the equipment operates at low speed, the amount of cigarettes replenished at the outlet decreases, and the cigarettes continue to be conveyed by the conveyor belt. The cigarette flow controller 47 is raised, and the speed of the cigarette conveyor belt slows down until it stops. When the equipment operates at high speed, the amount of cigarettes replenished at the outlet increases, and the cigarette flow controller 47 descends. At this time, the speed of the cigarette conveyor belt increases, and cigarettes are replenished quickly. When the cigarettes in a cigarette storage pan 20 are emptied, and the cigarette level detector 56 fails to detect the presence of cigarettes again, the conveyor belt stops, the unloading cylinder retracts, and after a 2-second delay, the cylinder is raised. The cylinder operates to lift the empty smoke storage tray 20. When the lifting cylinder is at its highest position, the clamping cylinder 9 disengages, clamping the smoke storage tray 20. After a 1.5-second delay, the retraction cylinder 10 disengages, retracting the empty smoke storage tray 20 to its exit position. When the empty smoke tray position detector 55 detects a signal, the lifting cylinder moves downward to its lowest position. When the upper position detector 54 of the lifting cylinder detects that it is empty, the clamping cylinder 9 disengages, and after a 1.5-second delay, the retraction cylinder 10 moves forward, waiting for the next empty smoke storage tray 20, thus completing the work cycle.

[0133] This application is primarily applied to the field of adding recycled cigarettes to cigarette storage drums in the tobacco industry. It addresses the issue of adding recycled cigarettes within the context of cigarette storage drums used in cigarette rolling and packaging units. It replaces the traditional manual cigarette adding method with a fully automated one, achieving automation of cigarette adding while ensuring quality, thus improving the efficiency of recycled cigarette adding. The automatic cigarette adding device consists of four parts: a bottom-openable cigarette storage tray, automatic feeding and retraction of the tray, cigarette unloading and adding, and a control system. Operators at the packaging machine prepare the recycled cigarettes and place them into the storage tray. The full tray is then placed on the automatic adding device, and the device is activated by pressing the control button, completing the fully automated addition of recycled cigarettes. After being put into use, it ensures the quality of recycled cigarettes, significantly improves the efficiency of cigarette adding, and reduces cigarette consumption.
