Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing, and in particular to a container and a device and method for emptying materials from the container. Background Art

[0002] In the tobacco processing process, the produced rod-shaped materials such as cigarettes and multi-segment filters need to be transferred or stored between the continuous production equipment of the production line. The prior art uses a hexahedral tray with two open sides to store, transfer, and then empty the materials in the tray. The process of emptying the materials is generally to flip the tray 180°, drop the materials into the silo and transport them to the downstream unit. Since the tray is open on both sides, the materials will be messy and roll off during the flipping process, especially for materials with shorter lengths. These phenomena affect the operation of the downstream unit and urgently require manual intervention, resulting in low production efficiency and waste of materials. Some improved technologies also have unreasonable aspects. For example, a container emptying method included in CN 106562472 A uses an arc plate to lift the materials from the container along the container conveying direction. In this process, the materials at the front and rear ends of the container are severely squeezed, which can easily cause the materials to deform or even break, especially for medium and thin rod-shaped materials with smaller diameters. These existing technologies or published technologies will have an adverse effect on the quality of the materials. Summary of the invention

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0091] For the convenience of explanation, Figure 2 and Fig.13 The left direction in the plane shown is defined as the left direction. Fig.13The right direction in the plane shown is defined as the right direction. Fig.13 The upper direction in the plane shown is defined as up, and the upper direction in FIG. Fig.13 The lower side direction in the plane shown is defined as down, and the vertical direction is perpendicular to FIG. Fig.13 The outward direction of the plane shown is defined as the forward direction, which is perpendicular to Figure 2 and Fig.13 The direction inward from the plane shown is defined as the rear direction. Fig.13 The direction from right to left in the plane shown is defined as the container conveying direction.

Fig.13 The up-down direction within the illustrated plane is defined as the height direction of the container 5 . Example 1

[0092] This embodiment is used to provide a new type of container for containing materials.

[0093] Please refer to Figure 1 The container 5 of the present invention is surrounded by four side panels and a bottom panel 55, and is in the shape of a rectangular box with a cavity inside and an open top.

[0094] The side uprights include a front upright 51, a rear upright 52, a left upright 53, and a right upright 54. The front upright 51 and the rear upright 52 are respectively fixed to the top front end and the rear end of the bottom plate 55.

[0095] Referring to FIG. 2 , the left vertical plate 53 and the right vertical plate 54 are respectively fixed obliquely on the top left and right sides of the bottom plate 55, so that the internal cavity of the container 5 forms a bucket-shaped cavity with a larger top and a smaller bottom. A first sunken groove 56 is provided on the right side of the left vertical plate 53, a second sunken groove 57 is provided on the top surface of the bottom plate 55, and a third sunken groove 58 is provided on the left side of the right vertical plate 54. In the embodiment of the present invention, the first groove 56, the second groove 57, and the third groove 58 are provided, so that the material in the container 5 can be taken out by first inserting the material taking mechanism (such as a plug plate) into the first groove 56, and then passing through the second groove 57 and the third groove 58 in sequence, and then the relative movement of the tool and the container 5. At the same time, since the grooves on the left vertical plate 53, the right vertical plate 54 and the bottom plate 55 are not grooves that pass through the side and bottom of the container 5, the sealing of the container 5 after the lid is closed can be ensured, avoiding the volatilization of the aroma of the cigarettes and other materials stored in the container 5 due to exposure to the air, thereby further improving the quality of the materials stored in the container 5.

[0096] Preferably, the first groove 56, the second groove 57, and the third groove 58 are interconnected. In this embodiment, the grooves on the left vertical plate 53, the right vertical plate 54, and the bottom plate 55 are aligned and connected to each other, which can further improve the material emptying efficiency in the container 5.

[0097] In some optional embodiments, the left vertical plate 53 and the right vertical plate 54 are both straight plates, and the inclination angle of the left vertical plate 53 and the right vertical plate 54 relative to the bottom plate 55 is in the range of greater than or equal to 15° and less than or equal to 80°, so as to obtain better efficiency in emptying materials from the container 5.

[0098] In some other optional embodiments, the bottom of the left vertical plate 53 and the right vertical plate 54 can be a concave arc-shaped plate. In these embodiments, the left and right vertical plates are designed as arc-shaped plates, especially the arc of the left vertical plate 53 is tangent to the bottom plate 55, and the arc of the right vertical plate 54 is tangent to the bottom plate 55, which can make the transition between the second groove 57 and the first and third grooves 58 on both sides smoother, so that the material taking mechanism moves more smoothly in the first groove 56, the second groove 57, and the third groove 58 that penetrate each other, so as to obtain a better material taking effect and improve the container emptying efficiency.

Preferably, as Fig. 9 and Fig.10 As shown in the figure, the lower side of the material support plate 321 is a shovel-shaped lower surface that is inclined relative to the upper surface to form a thinner end portion, and the middle portion of the upper side of the material support plate 321 is hollowed out, and the material supporting roller 323 and the third conveyor belt 322 are assembled in the hollowed-out position so that the uppermost surface of the third conveyor belt 322 is aligned with the shovel-shaped upper surface of the lower side of the material support plate 321.

[0132] In some optional embodiments, the container emptying mechanism 3 further includes: a left conveyor 33 and a right conveyor 31; wherein the left conveyor 33 and the right conveyor 31 are relatively arranged downstream of the material taking mechanism 32, and a first material conveying channel is formed between the left conveyor 33 and the right conveyor 31; the left conveyor 33 and the right conveyor 31 are used to convey the material output by the material taking mechanism 32 to the entrance of the material conveying mechanism 4. Preferably, as Figure 8 As shown in the figure, the container emptying mechanism 3 is arranged above the container conveying mechanism 2, the material picking mechanism 32 is located between the full container conveyor 22 and the empty container conveyor 23 in Example 4, the left conveyor 33 is arranged above the container conveying mechanism 2, and the right conveyor 31 is arranged on the right side of the left conveyor 33, and a first material conveying channel is formed between the left conveyor 33 and the right conveyor 31.

[0133] Preferably, the left conveyor 33 includes a plurality of first guide rollers 331, a first driving roller 333, and a second driving motor, and a first conveyor belt 332 is installed outside the first guide roller 331 and the first driving roller 333; the first guide roller 331 and the first driving roller 333 are both rotatably installed at the front end of the fixed main board 10, and a second driving motor for driving the first driving roller 333 to rotate is installed at the rear end of the fixed main board 10;

[0134] The right conveyor 31 includes a plurality of second guide rollers 311, a second driving roller 313 and a third driving motor, and a second conveyor belt 312 is installed on the outer side of the second guide roller 311 and the second driving roller 313; the second guide roller 311 and the second driving roller 313 are both rotatably installed on the front end of the fixed main board 10; and the third driving motor for driving the second driving roller 313 to rotate is installed on the rear end of the fixed main board 10.

[0135] The second and third driving motors drive the first driving roller 333 and the second driving roller 313 to rotate via a gear or pulley structure, and the specific structure thereof is a well-known technology in the technical field and will not be described in detail in this embodiment.

[0136] Preferably, the width of the first material conveying channel ( Figure 8 The shortest distance between the first conveyor belt 332 of the middle left conveyor 33 and the second conveyor belt 312 of the right conveyor 31 is less than the height of the internal cavity of the container 5.

[0137] In some preferred embodiments, see Fig. 9 and Fig.10 , the material support plate driving mechanism includes:

[0138] The second electric cylinder slide 327 is fixedly mounted on the rear end of the fixed main board 10 and extends along the first direction; wherein the first direction forms a predetermined angle with the horizontal direction; preferably, the first direction is parallel to the extension direction of the first groove 56 on the left vertical plate 53 (the inclination direction of the first groove 56 relative to the horizontal direction);

[0139] A second electric cylinder 326, which is mounted on one end of a second electric cylinder slide 327;

[0140] The motor mounting plate is slidably connected to the rear end of the second electric cylinder slide 327, and the motor mounting plate is connected to the output end of the second electric cylinder 326, so as to make the motor mounting plate slide along the second electric cylinder slide 327 under the drive of the second electric cylinder 326; the material support plate 321 is fixedly connected to the front side of the motor mounting plate through a connecting plate;

[0141] The first driving motor 325 is installed on the rear side of the motor mounting plate, and the output end of the first driving motor 325 is connected to one of the at least two supporting rollers 323 of the material supporting plate 321 through the gear transmission mechanism 324 to drive it to rotate.

[0142] Furthermore, a second avoidance groove is also provided on the front side of the fixed main board 10 to provide avoidance space for the material support plate 321 when it slides.

[0143] By means of the arrangement of this mechanism, when the container 5 filled with materials is pushed to the working station of the material taking mechanism 32 by the container pushing mechanism 1, the second electric cylinder 326 drives the material support plate 321 to move obliquely downward, first extending into the first groove 56 on the left side of the container 5, so that the material support plate 321 is Figure 8 As shown in the figure, the material extends into the container 5 below, and the first drive motor 325 is started at this time, and the third conveyor belt 322 is driven by the rotation of the support roller 323. Under the rotation of the third conveyor belt 322, the material is driven upward to between the left conveyor 33 and the right conveyor 31, and is transported upward through the material conveying channel formed between the first conveyor belt 332 and the second conveyor belt 312. At the same time, the lower conveyor 21 is controlled to convey the container 5 to the left. In the process of conveying the container 5 to the left, the material support plate 321 will successively enter the second groove 57 and the third groove 58 of the container 5. According to the same principle, in the process of the movement of the container 5, the container emptying mechanism 3 completes the material picking action. Among them, the first drive motor 325 can be adjusted to the required speed according to the container emptying speed, so that the surface line speed of the third conveyor belt 322 is the same as the surface line speed of the first conveyor belt 332 of the left conveyor 33.

[0144] The container emptying mechanism 3 provided in the embodiment of the present disclosure, the material support plate 321 reciprocatingly slides into the groove in the container 5, which can increase the power of lifting and conveying the material in the container 5. When emptying the material at the right end of the container, Fig.11 As shown in the figure, the material support plate 321 slides in the third groove 58 of the right vertical plate 54 of the container 5. As the container is transported to the left, the material will be subjected to the upward component force from the right vertical plate 54, reducing the wrinkling of the material due to extrusion, which is particularly suitable for the transportation of soft rod-shaped objects such as filter rods and cigarettes. Example 7

[0145] This embodiment is used to disclose a specific structure of the material conveying mechanism 4 in the above-mentioned embodiment 2.

[0146] See also Fig.12 The material conveying mechanism 4 is located downstream of the left conveyor 33 in the sixth embodiment.

[0147] The material conveying mechanism 4 includes an upper conveyor 41 and a lower conveyor 42 installed at the front end of the fixed main board 10. The upper conveyor 41 and the lower conveyor 42 both include a driving wheel and a passive wheel. The outer sides of the driving wheel and the passive wheel are connected by a transmission belt. A second material conveying channel is formed between the transmission belts of the upper conveyor 41 and the lower conveyor 42.

[0148] As above, the driving wheels of the upper conveyor 41 and the lower conveyor 42 are driven to rotate by a seventh driving motor installed at the rear end of the fixed main board 10. The seventh driving motor drives the driving driving wheel 24 to rotate through a gear or pulley structure, and its specific structure is a well-known technology in the technical field, and will not be described in detail in this embodiment.

[0149] In addition, the material conveying mechanism 4 may further include a transition plate or a flexible transition belt, which is arranged between the upper conveyor 41, the lower conveyor 42 and the output port of the container emptying machine 3 for receiving the material output by the container emptying mechanism 3. Example 8

[0150] This embodiment discloses a specific method for emptying materials from a container 5 , and this method is used for the device for emptying materials from a container provided in any of the aforementioned embodiments. Fig.13 A schematic diagram of an apparatus for emptying materials from a container provided by the present disclosure and emptying materials from a container.

[0151] The method provided in this embodiment includes the following steps:

[0152] S1. Full container delivery:

[0153] The container conveying mechanism 2 conveys the container 5 filled with materials to the material taking station of the container emptying mechanism 3;

[0154] S2. Container emptying:

[0155] When the container 5 filled with materials is transported to the material taking mechanism 32 station of the container emptying mechanism 3, the material taking mechanism 32 of the container emptying mechanism 3 extends into the first groove 56 of the container 5 filled with materials;

[0156] The container 5 is conveyed to the left by the container conveying mechanism 2. During the conveying process of the container 5 to the left, the material is taken out by the material taking mechanism 32 on the material taking mechanism 32, and the material is lifted obliquely upward and conveyed to the material conveying mechanism 4 by the left conveyor 33 and the right conveyor 31;

[0157] S3. Empty container transportation:

[0158] The emptied container 5 is further transported to the next station for filling the container by the container conveying mechanism 2 ; and the removed material is further transported to the next material demanding station by the material conveying mechanism 4 .

[0159] Preferably, in the above method, before the container conveying mechanism 2 conveys the container 5 filled with materials to the material picking station of the container emptying mechanism 3 , S1 further includes the step of the container pushing mechanism 1 pushing the container 5 filled with materials into the container conveying mechanism 2 .

[0160] It can be seen from the above embodiments that the present invention has the following advantages and effects:

[0161] The structure of the container 5 designed by the present invention is that the left vertical plate 53 and the right vertical plate 54 are inclined. When gradually taking materials, the right vertical plate 54 is squeezed by the materials and can give the materials an oblique upward component force to prevent the materials from being squeezed and damaged, thereby improving the quality of the materials. The present invention can automatically realize the removal of materials and improve the material removal efficiency through the arrangement of the container pushing mechanism 1, the container conveying mechanism 2, the container emptying mechanism 3, and the material conveying mechanism 4. In addition, the container 5 is not turned over during the material taking process, which can effectively prevent the material from being confused and rolling.

[0162] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
