Description

Technical Field

[0001] This application relates to the technical field of heating cigarette feeding, and particularly to an automatic feeding device. Background Art

[0002] A high-speed wheel-type combined tipping and filtering machine is used to produce heated tobacco products, which are composed of base rods of multiple different materials. The heating cigarette base rod feeding device supplies base rods of different materials to the high-speed wheel-type combined tipping and filtering machine.

[0003] There is a stair landing behind the high-speed wheel-type combined tipping and filtering machine. Operators need to climb up this stair landing, place full trays of different types on the full tray table of the heating cigarette base rod feeding device, and take out the emptied empty trays on the heating cigarette base rod feeding device.

[0004] The work intensity of operators going up and down the stairs to carry materials is very high, and due to the relatively high stair landing, there is a risk of falling and getting injured. During the normal operation of the high-speed wheel-type combined tipping and filtering machine, the stair landing is placed fixed behind the machine set, and the stair landing is very heavy. Operators or maintenance personnel need to often open the cabinet door behind the high-speed wheel-type combined tipping and filtering machine to check or repair the equipment. This requires often moving the stair landing away, and after checking or repairing, the stair landing needs to be reset, increasing the daily work intensity. Summary of the Invention

[0041] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0042] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly disposed on the other element; when an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0043] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to this application.

[0044] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, the meanings of "a plurality" and "several" are two or more, unless otherwise specifically defined.

[0045] It should be noted that the structures, proportions, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the implementation conditions of this application. Therefore, they do not have any substantial technical significance. Any modification of the structure, change in the proportional relationship, or adjustment of the size, without affecting the effects that this application can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in this application.

[0046] Referring to Figure 1 , an automatic feeding device is provided in an embodiment of this application, which includes a material tray 100, a full-material table 200, an empty-material table 300, a loading and unloading robot 400, and a feeding mechanism 500. The feeding mechanism 500 is installed above the cigarette making and tipping unit to feed the cigarette making and tipping unit; multiple material trays 100 filled with base rods are placed on the full-material table 200, and multiple emptied material trays 100 are placed on the empty-material table 300; the loading and unloading robot 400 transfers the material tray 100 from the full-material table 200 to the feeding mechanism 500, and transfers the emptied material tray 100 from the feeding mechanism 500 back to the empty-material table 300; the loading and unloading robot 400 includes a transportation storage rack 410, a buffer table 420, and a loading and unloading mechanism 430. The loading and unloading mechanism 430 and the buffer table 420 are respectively arranged on both sides of the transportation storage rack 410; the loading and unloading mechanism 430 clamps the material tray 100 and rotates it, and then places the material tray 100 on the buffer table 420.

[0047] In the embodiment of this application, the stair platform on the cigarette making and tipping unit is cancelled. The loading and unloading robot 400 is used to transport the material tray 100 filled with base rods on the full-material table 200 to the feeding mechanism 500, and take out the emptied material tray 100 on the feeding mechanism 500 and put it back on the empty-material table 300. The operator does not need to go up and down the stairs. The operator only needs to fill the empty material tray 100 with base rods on the empty-material table 300 and place it on the corresponding full-material table 200, which greatly reduces the working intensity of the operator and reduces the risk of falling. The cancellation of the stairs also enables the operation and maintenance personnel to easily open the cabinet door behind the cigarette making and tipping unit to operate or maintain the unit without having to move the stairs away each time.

[0048] Referring to Figures 2 to 4, in the embodiments of the present application, the base rods are contained in the trays 100 on the full material platform 200, and the trays 100 on the empty material platform 300 are empty. Since heated cigarettes require base rods of various different sizes and materials, multiple full material platforms 200 are provided, and the base rod specifications contained in the trays 100 placed on each full material platform 200 are different. That is to say, base rods of different specifications can be stored on different full material platforms 200. To facilitate the operator to load the trays 100 and transfer the trays 100 from the empty material platform 300 to the full material platform 200 after being filled, the corresponding empty material platform 300 is placed on one side of the full material platform 200. Further, the numbers of the full material platforms 200 and the empty material platforms 300 are both multiple. The multiple full material platforms 200 are arranged at intervals, and the multiple empty material platforms 300 are arranged at intervals. At least one side of each full material platform 200 is provided with an empty material platform 300.

[0049] Refer to Figures 5 to 7 , in the embodiments of the present application, the loading and unloading robot 400 is movable, capable of moving on a set route and having an obstacle avoidance function. The loading and unloading mechanism 430 and the buffer platform 420 are respectively arranged on both sides of the transportation and storage rack 410 to avoid interference with each other during operation and facilitate the movement of the loading and unloading mechanism 430 on the transportation and storage rack 410 and the placement of the tray 100 on the buffer platform 420. Therefore, the loading and unloading mechanism 430 needs to be able to rotate to facilitate placing the tray 100 on the buffer platform 420. Among them, one tray 100 is placed on each buffer platform 420, and the number of buffer platforms 420 is multiple, enabling the loading and unloading robot 400 to transport multiple trays 100 at a time.

[0050] In some embodiments, the number of buffer platforms 420 is multiple, and the multiple buffer platforms 420 are arranged at intervals along the vertical direction of the transportation and storage rack 410; the loading and unloading mechanism 430 includes a mounting component, a rotating component, and a clamping component. The mounting component is movably arranged on the transportation and storage rack 410 to move along the vertical direction of the transportation and storage rack 410, the rotating component is rotatably arranged on the mounting component to transfer the tray 100 to the buffer platform 420, and the clamping component is arranged on the rotating component to pick up and place the tray 100.

[0051] Refer to Figures 9 to 12, in the embodiments of the present application, the installation component can move along the vertical direction of the transportation storage rack 410, which is convenient for adjusting the positions of the rotating component and the clamping component, so as to meet the needs of grasping and placing the tray 100. In addition, a plurality of buffer platforms 420 are arranged along the vertical direction of the transportation storage rack 410. The installation component moving along the vertical direction facilitates the rotating component and the clamping component to place the tray 100 on different buffer platforms 420. After the loading and unloading robot 400 moves to the vicinity of the feeding mechanism 500, it first places all the trays 100 filled with base rods on the feeding mechanism 500, and then retrieves the emptied trays 100 on the feeding mechanism 500 one by one to the buffer platform 420; alternatively, for each tray 100 clamped to the feeding mechanism 500, when retrieving, one emptied tray 100 is clamped and retrieved to the buffer platform 420. There is no limitation on the above movement trajectory of the loading and unloading robot 400 here.

[0052] In some embodiments, the clamping component includes two clamping parts arranged opposite to each other and at intervals. The clamping part includes a first driving unit, a second driving unit, a guiding unit and a clamping plate 4331. The first driving unit and the guiding unit are respectively fixed on the rotating component; the output end of the first driving unit is connected to the clamping plate 4331 to drive the clamping plate 4331 to approach or move away from the transportation storage rack 410, and the guiding unit is connected to the clamping plate 4331 to guide the clamping plate 4331. The second driving unit is installed on the guiding unit and its output end is fixed on the clamping plate 4331 to push the clamping plate 4331 to approach or move away from the guiding unit.

[0053] In the embodiments of the present application, the two clamping parts are arranged at intervals and opposite to each other to grasp the tray 100. The first driving unit can drive the clamping plate 4331 to approach or move away from the transportation storage rack 410, that is, to extend or retract the clamping plate 4331 outward, so as to facilitate grasping and retrieving the tray 100. Existing driving forms can all be applied to the first driving unit. In the embodiments of the present application, the first driving unit can drive the two clamping parts to act simultaneously. The first driving unit includes a first servo motor 4332, an output shaft 4333, a driving wheel, a driven wheel, a chain and a slider 4334. The output end of the first servo motor 4332 is connected to the output shaft 4333. The two ends of the output shaft 4333 are respectively connected to a driving wheel to drive the driving wheel to rotate. A chain is installed on each of the driving wheel and the driven wheel, and the chain moves as the driving wheel rotates. A slider 4334 is fixed on each chain, and the clamping plates 4331 are respectively fixed on the sliders 4334, so that the clamping plates 4331 move along the extension direction of the chain. The first driving unit further includes a rotating shaft, which is rotatably arranged on the rotating component, and its two ends are respectively connected to a driven wheel and rotate together with the driven wheel.

[0054] In the embodiments of the present application, the guiding unit guides the clamping plate 4331 to prevent the clamping plate 4331 from shifting during movement. The guiding unit includes a guiding plate 4335, two guide rods 4336 and two sliding shafts 4337. The guiding plate 4335 is connected to the clamping plate 4331 through the two sliding shafts 4337, enabling the clamping plate 4331 to move along the sliding shafts 4337 to approach or move away from the guiding plate 4335. The guiding plate 4335 is respectively slidably disposed on the two guide rods 4336, and the guide rods 4336 are fixed to the rotating assembly. When the clamping plate 4331 approaches or moves away from the transportation and storage rack 410, the guiding plate 4335 moves along the guide rods 4336 simultaneously, thereby guiding the clamping plate 4331.

[0055] In the embodiments of the present application, the second driving unit drives the clamping plate 4331 to move along the sliding shafts 4337 to increase or decrease the distance between the two clamping plates 4331, thereby grasping or releasing the tray 100. The second driving unit can be a servo push rod 4338. The servo push rod 4338 is fixed to the guiding plate 4335, and the output end of the servo push rod 4338 is connected to the clamping plate 4331, capable of pushing the clamping plate 4331 to move along the sliding shafts 4337.

[0056] In some embodiments, the mounting assembly includes a mounting plate 4311, a driving motor 4312, a sprocket and a chain. The output end of the driving motor 4312 is connected to the sprocket to drive the sprocket to rotate. The chain meshes with the sprocket and moves along the extending direction of the transportation and storage rack 410 under the drive of the sprocket. The mounting plate 4311 is fixed to the chain and slides on the transportation and storage rack 410.

[0057] In the embodiments of the present application, the driving motor 4312 is fixed to the transportation and storage rack 410. The sprocket includes a driving sprocket and a driven sprocket. The output end of the driving motor 4312 is connected to the driving sprocket, and the driven sprocket is installed on the transportation and storage rack 410. The chain moves under the drive of the driving sprocket and the driven sprocket. The mounting plate 4311 is fixed to the chain and moves together with the chain. A guide rail groove is formed on the transportation and storage rack 410, and the mounting plate 4311 slides up and down in the guide rail groove.

[0058] In some embodiments, the rotating assembly includes a turntable 4321, a flange shaft 4322 and a second servo motor 4323. The output end of the flange shaft 4322 is fixed to the turntable 4321. The flange shaft 4322 is rotatably disposed on the mounting assembly, specifically, the flange shaft 4322 is rotatably disposed on the mounting plate 4311. The second servo motor 4323 is fixed to the mounting plate 4311, and the output end of the second servo motor 4323 is connected to the flange shaft 4322. It can be understood that the second servo motor 4323 drives the flange shaft 4322 to rotate, so that the turntable 4321 rotates on the mounting plate 4311, and after grasping the tray 100, it rotates towards the buffer table 420, thereby placing the tray 100 on the buffer table 420.

[0059] In some embodiments, the full material table 200 includes a first conveying assembly 210 and a first separating mechanism. The tray 100 is placed on the first conveying assembly 210 and moves therewith. The first separating mechanism is disposed on both sides of the first conveying assembly 210 to convey a preset number of trays 100 to the front end of the first conveying assembly 210.

[0060] In the embodiments of the present application, the first conveying assembly 210 drives the tray 100 thereon to move and sends the tray 100 to the front end of the first conveying assembly 210. After the first separating mechanism detects that a preset number of trays 100 are conveyed to the front end of the first conveying assembly 210, it can block the trays 100 outside the preset number from continuing to move to the front end, so that the number of trays 100 at the front end matches the number that the clamping assembly of the loading and unloading robot 400 can grasp.

[0061] Specifically, the automatic feeding device includes a control unit. The first separating mechanism includes a first bracket 221, a first photoelectric switch 222 and a first cylinder 223. The first brackets 221 are disposed on both sides of the first conveying assembly 210. The first photoelectric switch 222 and the first cylinder 223 are disposed on each first bracket 221. The first photoelectric switch 222 detects the number of trays 100 passing by and transmits the number information of the trays 100 to the control unit. The control unit controls the output end of the first cylinder 223 to extend and block the trays 100 outside the preset amount so that a preset number of trays 100 are conveyed to the front end of the first conveying assembly 210.

[0062] In the embodiments of the present application, the first conveying assembly 210 may include a conveyor belt. The tray 100 is placed on the conveyor belt and is conveyed to its front end by the conveyor belt. A baffle is formed at the front end of the first conveying assembly 210 to prevent the tray 100 from falling off the conveyor belt. The first brackets 221 are disposed on both sides of the first conveying assembly 210, and the first photoelectric switch 222 and the first cylinder 223 are installed on each first bracket 221. The first photoelectric switch 222 can detect the number of trays 100 passing by it and transmit the number information to the control unit. According to the preset number information of the trays 100, when the number of trays 100 at the front end of the conveyor belt meets the preset requirements, the control unit controls the first cylinder 223 to act to block the subsequent trays 100 from continuing to move forward.

[0063] There are various ways for the output end of the first cylinder 223 to extend out and block the rear tray 100. In the embodiments of the present application, through holes are respectively provided on both sides of the tray 100, and the output end of the first cylinder 223 extends into the corresponding through holes. It can be understood that when trays 100 exceeding the preset quantity are conveyed to the position of the first cylinder 223, the control unit controls the output end of the first cylinder 223 to extend into the through holes of the tray 100, thereby preventing the tray 100 from continuing to move.

[0064] In some embodiments, the feeding mechanism 500 includes a base 510, an input component 520, an output component 530, and a lifting mechanism. The base 510 is fixed to the top of the tipping and linking unit. The input component 520 and the output component 530 are spaced apart and installed on the base 510. The input component 520 is arranged close to the top of the tipping and linking unit, and the output component 530 is arranged above the input component 520. The loading and unloading robot 400 transfers the full tray 100 to the input component 520 to open the bottom of the tray 100 and feed the tipping and linking unit, and the lifting mechanism transfers the emptied tray 100 to the output component 530, and the loading and unloading robot 400 transfers the emptied tray 100 from the output component 530 to the empty tray table 300.

[0065] Referring to Figure 8 , in the embodiments of the present application, the base 510 is installed on the top of the tipping and linking unit, and the input component 520 on the base 510 receives the tray 100 filled with filter rods transported by the loading and unloading robot 400. The tray 100 is placed at the front end of the input component 520 by the clamping component. The input component 520 conveys the tray 100 along a straight line to the top feed port of the tipping and linking unit through a linear motion mechanism, and the filter rods in the tray 100 fall into the tipping and linking unit by opening the bottom cover of the tray 100. The emptied tray 100 is transferred to the output component 530 by the lifting mechanism, and the clamping component of the loading and unloading robot 400 grabs the emptied tray 100 from the output component 530 and transfers it to the empty tray table 300.

[0066] Further, the output component 530 includes a second conveying component and a second separating mechanism. The emptied tray 100 is placed on the second conveying component and moves therewith. Second separating mechanisms are respectively arranged on both sides of the second conveying component to convey a preset quantity of trays 100 to the front end of the second conveying component.

[0067] In the embodiments of the present application, the second conveying component drives the tray 100 thereon to move and sends the tray 100 to the front end of the second conveying component. After the second separating mechanism detects that a preset quantity of trays 100 are conveyed to the front end of the second conveying component, it can block the trays 100 exceeding the preset quantity from continuing to move to the front end, so that the quantity of trays 100 at the front end matches the quantity that the clamping component of the loading and unloading robot 400 can grab.

[0068] Specifically, the automatic feeding device includes a control unit. The second separation mechanism includes a second support, a second photoelectric switch, and a second cylinder. Second supports are respectively arranged on both sides of the second conveying assembly. A second photoelectric switch and a second cylinder are arranged on each second support. The second photoelectric switch detects the number of trays 100 passing by, and transmits the number information of the trays 100 to the control unit. The control unit controls the output end of the cylinder to extend and block the trays 100 outside the preset number, so that the trays 100 of the preset number are conveyed to the front end of the second conveying assembly.

[0069] In the embodiment of the present application, the second conveying assembly may include a conveyor belt. The tray 100 is placed on the conveyor belt and conveyed to its front end by the conveyor belt. A baffle is formed at the front end of the second conveying assembly to prevent the tray 100 from falling off the conveyor belt. Second supports are respectively arranged on both sides of the second conveying assembly, and a second photoelectric switch and a second cylinder are installed on each second support. The second photoelectric switch can detect the number of trays 100 passing by it and transmit the number information to the control unit. According to the preset number information of the trays 100, when the number of trays 100 at the front end of the conveyor belt meets the preset requirements, the control unit controls the second cylinder to act to block the subsequent trays 100 from continuing to move forward.

[0070] There are various ways for the output end of the second cylinder to extend and block the subsequent tray 100. In the embodiment of the present application, through holes are respectively arranged on both sides of the tray 100, and the output end of the second cylinder extends into the corresponding through holes. It can be understood that when the trays 100 outside the preset number are conveyed to the position of the second cylinder, the control unit controls the output end of the second cylinder to extend into the through holes of the tray 100, thereby preventing the tray 100 from continuing to move.
