Description

Technical Field

[0001] This utility model belongs to the field of cigarette production technology, specifically relating to a boxed filter rod sorting device. Background Technology

[0002] As part of cigarette products, the quality of filter rods is also an important component of cigarette product quality. Utility model patents CN208972665U ("A Detection and Rejection Device and Receiver for Bean Capsule Filter Rods") and CN214160565U ("An Online Sorting Device for Bean Capsule Filter Rods with a Defective Sample Rejection Mechanism") describe devices that detect filter rods during transport and then sort them out using gas jets. However, for already packaged filter rods, the above solutions, when applied to sorting already packaged filter rods, can carry away a large number of non-picking objects during gas jetting, thus affecting the filter rod sorting effect. Utility Model Content

[0003] The purpose of this invention is to provide a boxed filter rod sorting device, which uses an air blowing mechanism to drive a picking needle to penetrate the filter rod and grab the filter rod inside the box, thereby ensuring that no non-picking objects are carried when the already grabbed filter rod is removed from the box, thus improving the filter rod picking effect.

[0004] The technical solution adopted by this utility model to solve its technical problem is to propose a boxed filter rod sorting device, including a needle sleeve with a picking cavity, a picking needle disposed in the picking cavity, and an air blowing assembly disposed around the needle sleeve; the needle sleeve is provided with an air guide hole, and the air blowing assembly introduces air into the picking cavity through the air guide hole to push the picking needle to move within the needle sleeve, and the picking needle penetrates into the filter rod to grasp the filter rod.

[0005] In this embodiment, the picking chamber includes a guide chamber and a compression chamber, and the picking needle includes an integrally connected needle seat and needle bar. The guide chamber communicates with the compression chamber, and the inner diameter of the guide chamber is equal to the outer diameter of the needle bar.

[0006] In this embodiment of the application, the compression chamber includes a first chamber and a second chamber, the distance between the first chamber and the air guide hole is smaller than the distance between the second chamber and the air guide hole, and the inner diameter of the first chamber is larger than the inner diameter of the second chamber.

[0007] In this embodiment of the application, a sealing ring is provided at one end of the compression chamber near the air guide hole.

[0008] In this embodiment of the application, a spring is also provided inside the compression chamber, one end of which is connected to the needle seat and the other end is fixed inside the compression chamber.

[0009] In this embodiment, the end of the needle sleeve away from the air guide hole is provided with a rounded corner.

[0010] In this embodiment of the application, the outer diameter of the needle holder is greater than the inner diameter of the second cavity, and the outer diameter of the needle holder is less than or equal to the inner diameter of the first cavity.

[0011] In this embodiment of the application, the air blowing assembly includes an air tube and an air source, with one end of the air tube connected to the air guide hole and the other end connected to the air source.

[0012] In this embodiment of the application, the boxed filter rod sorting device further includes a controller and a moving component. The controller is electrically connected to the air blowing assembly and the moving component, and the moving component is connected to the air blowing assembly. The moving component is used to drive the air blowing assembly, the needle sleeve and the picking needle to move.

[0013] In this embodiment, the boxed filter rod sorting device further includes an alarm light column, which is electrically connected to the controller.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The present invention proposes a boxed filter rod sorting device, which uses an air blowing device to drive a picking needle to penetrate into the filter rod to grab the filter rod in the box, thereby ensuring that no non-picking objects are carried when the already grabbed filter rod is removed from the box, thus improving the filter rod picking effect.

[0016] 2. The present invention proposes a boxed filter rod sorting device, which sets the inner diameter of the guide cavity to be equal to the outer diameter of the needle rod. When the picking needle moves, the needle rod of the picking needle moves in a straight line under the guidance of the guide cavity, so that the picking needle does not shake when it moves, thus ensuring the stability when picking up the filter rod.

[0017] 3. The present invention proposes a boxed filter rod sorting device, wherein the inner diameter of the first chamber is larger than the inner diameter of the second chamber, thereby making the gas flow velocity in the first chamber lower than the gas flow velocity in the second chamber, and the pressure in the second chamber lower than the pressure in the first chamber. This causes the picking needle to form a pressure difference along the direction from the first chamber to the second chamber, and the pressure difference generates a force toward the second chamber, thereby enhancing the thrust on the picking needle.

[0018] 4. The boxed filter rod sorting device proposed in this utility model, after the filter rod is removed from the cigarette box, the blowing component no longer delivers air to the picking chamber. The spring pushes the needle seat to move under the action of the restoring force, the picking needle is reset, the picking needle is separated from the filter rod, and then the next filter rod is picked up, thus ensuring the continuous use of the boxed filter rod sorting device.

[0019] 5. The present invention proposes a boxed filter rod sorting device in which the outer diameter of the needle holder is greater than the inner diameter of the second cavity, and the outer diameter of the needle holder is less than or equal to the inner diameter of the first cavity. In this way, the needle holder only moves within the first cavity, thereby avoiding the spring from breaking due to stress concentration under excessive compression. Attached Figure Description

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model and the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0028] This utility model embodiment provides a boxed filter rod sorting device. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 It mainly includes needle sheath 2, picking needle 3 and air blowing assembly 4.

[0029] In this embodiment, the boxed filter rod sorting device includes a needle sleeve 2, a picking needle 3, and an air blowing assembly 4. The needle sleeve 2 is cylindrical and has a picking cavity 1. The picking needle 3 is arranged in the picking cavity 1, and the air blowing assembly 4 is arranged around the needle sleeve 2. The needle sleeve 2 is also provided with an air guide hole 5. The air blowing assembly 4 delivers air to the picking cavity 1 through the air guide hole 5. The air in the picking cavity 1 pushes the picking needle 3 to move, so that the picking needle 3 extends out of the needle sleeve 2 and then inserts the picking needle 3 into the filter rod. Due to the existence of friction and the reaction force formed by the picking needle 3 inserting and squeezing the filter rod filaments, the picking needle 3 and the filter rod are tightly attached together. Then, the boxed filter rod sorting device can be moved by a moving cylinder, a robotic arm, or a guide rail to remove the filter rod. In this application, the air blowing unit drives the picking needle 3 to penetrate into the filter rod to grab the filter rod in the box, thereby ensuring that no non-picking objects are carried when the filter rod that has been grabbed is removed from the box, thus improving the filter rod picking effect.

[0030] In one possible implementation, the picking chamber 1 includes a guide chamber 11 and a compression chamber 12, which are connected. The distance between the guide chamber 11 and the guide hole is greater than the distance between the compression chamber 12 and the guide hole. The picking needle 3 includes an integrally connected needle base 31 and needle rod 32. The outer diameter of the needle rod 32 is equal to the inner diameter of the guide chamber 11. By setting the inner diameter of the guide chamber 11 to be equal to the outer diameter of the needle rod 32, when the picking needle 3 moves, the needle rod 32 of the picking needle 3 moves linearly under the guidance of the guide chamber 11, so that the picking needle 3 does not shake when it moves, thus ensuring the stability when picking up the filter rod.

[0031] Furthermore, the compression chamber 12 includes a first chamber 121 and a second chamber 122. The distance between the first chamber 121 and the air guide hole 5 is smaller than the distance between the second chamber 122 and the air guide hole 5. The inner diameter of the first chamber 121 is larger than the inner diameter of the second chamber 122, which makes the gas flow velocity in the first chamber 121 smaller than the gas flow velocity in the second chamber 122. The pressure in the second chamber 122 is smaller than the pressure in the first chamber 121. This causes the picking needle 3 to form a pressure difference along the direction from the first chamber 121 to the second chamber 122. The pressure difference generates a force toward the second chamber 122, thereby enhancing the thrust on the picking needle 3.

[0032] Furthermore, a sealing ring 13 is provided at one end of the compression chamber 12 near the air guide hole 5 to improve the airtightness of the picking chamber 1 and thus prevent air leakage.

[0033] Furthermore, a spring 14 is also provided in the compression chamber 12. One end of the spring 14 is connected to the needle seat 31, and the other end is fixed in the compression chamber 12. In this way, when the picking needle 3 grabs the filter rod, the spring 14 will be subjected to compression force. Then, after the filter rod is removed from the cigarette box, the blowing assembly 4 no longer delivers air to the picking chamber 1. Under the action of the restoring force, the spring 14 pushes the needle seat 31 to move, the picking needle 3 resets, the picking needle 3 separates from the filter rod, and then the next picking of the filter rod is carried out, ensuring the continuous use of the boxed filter rod sorting device.

[0034] Preferably, the outer diameter of the needle seat 31 is larger than the inner diameter of the second cavity 122, and the outer diameter of the needle seat 31 is less than or equal to the inner diameter of the first cavity 121. In this way, the needle seat 31 only moves within the first cavity 121, thereby avoiding the spring 14 from breaking due to stress concentration under excessive compression.

[0035] In one possible implementation, the end of the needle sleeve 2 away from the air guide hole 5 is provided with a rounded corner 21 to prevent the needle sleeve 2 from scratching the filter rod.

[0036] In one possible implementation, the air blowing assembly 4 includes an air pipe 41 and an air source 42, with one end of the air pipe 41 connected to an air guide hole 5 and the other end connected to the air source 42.

[0037] In one possible implementation, the boxed filter rod sorting device further includes a controller and a moving part 6. The controller may be one or a combination of several of the following: a central processing unit (CPU), a graphics processing unit (GPU), and a modem. The moving part 6 may be one or a combination of several of the following: a moving cylinder, a robotic arm, or a guide rail. The controller is electrically connected to the air blowing assembly 4 and the moving part 6. The moving part 6 is connected to the air blowing assembly 4. The moving part 6 is used to drive the air blowing assembly 4, the needle sleeve 2, and the picking needle 3 to move. In actual production, the controller acquires and processes the filter rod images captured by the industrial camera and selects filter rods that do not meet the production standards. The moving part 6 drives the air blowing assembly 4, needle sleeve 2, and picking needle 3 to move directly above the filter rod. Then, the air blowing assembly 4 drives the picking needle 3 to pierce into the filter rod. After that, the moving part 6 drives the air blowing assembly 4, needle sleeve 2, picking needle 3, and the grasped filter rod to move. Then, the air blowing assembly 4 no longer delivers air to the picking chamber 1, thereby removing the unqualified filter rods for the next selection of unqualified filter rods.

[0038] Furthermore, the boxed filter rod sorting device also includes an alarm light column with red and green lights. The alarm light column is electrically connected to the controller. When a defective filter rod is detected, the alarm light column is red, and when no defective filter rod is detected, the alarm light column is green.
