Description

Technical Field

[0001] The utility model relates to the field of food and drug packaging machinery, in particular to a strip package weighing, conveying and sorting machine. Background Art

[0002] At present, pharmaceutical enterprises have higher and higher requirements for the production efficiency of strip packages. In order to prevent overshoot during the high-speed conveying of strip packages, a scheme of obliquely upward conveying of strip packages has been proposed on the market. Although this scheme is beneficial to prevent overshoot, it will also bring new problems: for solid strip package materials such as powders and granules, they will accumulate on one side, resulting in an increase in the thickness of the strip package and uneven thickness, affecting subsequent conveying and box packaging. For this reason, a scheme of first clamping the strip package and then vibrating it through a vibrator to make the material evenly distributed in the strip package has been proposed on the market. Although this scheme can make the solid material evenly distributed in the strip package, the clamping part and the frame need to be flexibly connected through a buffer mechanism to avoid vibration being transmitted to the frame, resulting in a relatively complex overall structure, reduced reliability, and slow material leveling speed, reducing the production efficiency of the whole line. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a strip package weighing, conveying and sorting machine with a simple structure, good reliability, high efficiency and reasonable layout.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A strip package weighing, conveying and sorting machine includes a weighing and conveying mechanism and a gathering and conveying mechanism. The weighing and conveying mechanism is successively provided with a material receiving station, a turning station, a weighing station and a weighing and rejection station along the conveying direction. A strip package material leveling device is arranged between the weighing and rejection station and the gathering and conveying mechanism. The heights of the weighing and conveying mechanism, the strip package material leveling device and the gathering and conveying mechanism gradually increase; the strip package material leveling device includes a bracket, a strip package clamping mechanism and a material leveling mechanism. The material leveling mechanism is arranged on the bracket, and the material leveling mechanism is connected with the strip package clamping mechanism to drive the strip package clamping mechanism to move reciprocally.

[0006] As a further improvement of the above technical solution: the material leveling mechanism includes a rotary driving part, an eccentric shaft connected with the rotary driving part, and a connecting part connected with the strip package clamping mechanism. A connecting hole is arranged on the connecting part, the eccentric shaft passes through the connecting hole, and there are gaps between the upper and lower sides of the eccentric shaft and the inner wall of the connecting hole.

[0007] As a further improvement of the above technical solution: a rolling bearing is further arranged at one end of the eccentric shaft located in the connecting hole.

[0008] As a further improvement of the above technical solution: the rotation driving member is a servo motor.

[0009] As a further improvement of the above technical solution: a material leveling and guiding assembly is provided between the bracket and the strip package clamping mechanism.

[0010] As a further improvement of the above technical solution: the material leveling and guiding assembly includes a first slide rail and a first slider cooperating with the first slide rail. The first slide rail is provided at both ends of the bracket, and the first slider is provided at both ends of the strip package clamping mechanism.

[0011] As a further improvement of the above technical solution: the strip package clamping mechanism includes a sliding seat, mounting beams provided on both sides of the sliding seat, and a clamping driving member for driving the sliding seat to reciprocate. A plurality of fixed clamping members are provided between the two mounting beams, and a plurality of movable clamping members are provided on the sliding seat. The plurality of movable clamping members and the plurality of fixed clamping members are arranged in one-to-one correspondence. The clamping driving member is provided on the mounting beam, and the material leveling mechanism is connected to the mounting beam.

[0012] As a further improvement of the above technical solution: a clamping guiding assembly is provided between the sliding seat and the mounting beam.

[0013] As a further improvement of the above technical solution: the clamping guiding assembly includes a second slide rail and a second slider cooperating with the second slide rail. The second slide rail is provided at both ends of the sliding seat, and the second slide rail is provided at both ends of the mounting beam.

[0014] As a further improvement of the above technical solution: the clamping driving member is a cylinder.

[0015] Compared with the prior art, the utility model has the advantages that: the strip bag weighing, conveying and sorting machine disclosed in the utility model, when working, the strip bag falls from the strip bag main machine through the material receiving station, and the strip bag is transferred to the flipping station, so that the strip bag is turned from a lying position to a standing position, which is convenient for further conveying and weighing of the strip bag. The strip bag is weighed and recorded when it passes the weighing station, and the strip bag with unqualified filling quantity is rejected by the weighing and rejecting station to avoid subsequent unnecessary actions, and the strip bag with qualified weighing enters the strip bag leveling device. The height of the weighing conveying mechanism, the strip bag leveling device and the gathering and conveying mechanism gradually increases, which is conducive to preventing overshoot when the strip bag is conveyed quickly, but it is also easy to cause the material in the strip bag to accumulate on one side. For this reason, the strip bag clamping mechanism clamps and fixes the strip bag with qualified weighing, and then the leveling mechanism drives the strip bag clamping mechanism to shake quickly and orderly, so that the material is evenly distributed along the length direction of the strip bag, ensuring that the thickness of the strip bag is basically consistent at all places. Finally, the gathering and conveying mechanism is used to input the gathering spacing of the strip packs that have passed the weighing and material mixing into the whole-line cartoning machine for packaging, which is conducive to ensuring the stability and smoothness of the cartoning process. The position and layout of the material mixing device are reasonable. Compared with the existing vibration material mixing, there is no need to set up a buffer structure for flexible connection. It has a simple structure, good reliability, and fast material mixing speed.

[0028] The present utility model will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0029] Figures 1 to 6An embodiment of the strip weighing, conveying and arranging machine of the utility model is shown. The strip weighing, conveying and arranging machine of the utility model comprises a weighing and conveying mechanism 5 and a gathering and conveying mechanism 6. The weighing and conveying mechanism 5 is provided with a material receiving station 51, a turning station 52, a weighing station 53 and a weighing and rejecting station 54 in sequence along the conveying direction. A strip material mixing device is provided between the weighing and rejecting station 54 and the gathering and conveying mechanism 6. The heights of the weighing and conveying mechanism 5, the strip material mixing device and the gathering and conveying mechanism 6 gradually increase. The strip material mixing device comprises a bracket 1, a strip clamping mechanism 2 and a mixing mechanism 3. The mixing mechanism 3 is provided on the bracket 1. The mixing mechanism 3 is connected to the strip clamping mechanism 2 to drive the strip clamping mechanism 2 to move back and forth.

[0030] For details, please refer to Figure 1 and Figure 2 , in the strip bag weighing, conveying and sorting machine of this embodiment, when working, the strip bag falls from the strip bag main machine through the material receiving station 51, and the strip bag is transferred to the flipping station 52, so that the strip bag is turned from a lying position to a standing position, which is convenient for further conveying and weighing of the strip bag. When the strip bag passes the weighing station 53, the weighing record is recorded, and the strip bags with unqualified filling quantity are rejected by the weighing and rejecting station 54 to avoid subsequent unnecessary actions. The strip bags that are weighed pass the strip bag leveling device. The height of the weighing conveying mechanism 5, the strip bag leveling device and the gathering and conveying mechanism 6 gradually increases, which is conducive to preventing overshoot when the strip bag is conveyed quickly, but it is also easy to cause the material in the strip bag to accumulate on one side. For this reason, the strip bag clamping mechanism 2 clamps and fixes the strip bag that is weighed, and then the leveling mechanism 3 drives the strip bag clamping mechanism 2 to shake quickly and orderly, so that the material is evenly distributed along the length direction of the strip bag, ensuring that the thickness of the strip bag is basically consistent at all places. Finally, the gathering and conveying mechanism 6 is used to input the gathering spacing of the strip packs that have passed the weighing and material mixing into the whole-line cartoning machine for packaging, which is conducive to ensuring the stability and smoothness of the cartoning process. The position and layout of the strip pack material mixing device are reasonable. Compared with the existing vibration material mixing, there is no need to set up a buffer structure for flexible connection, the structure is simple, the reliability is good, and the material mixing speed is fast.

[0031] Furthermore, in this embodiment, the material leveling mechanism 3 includes a rotary drive member 31, an eccentric shaft 32 connected to the rotary drive member 31, and a connecting member 33 connected to the strip bag clamping mechanism 2. The connecting member 33 is provided with a connecting hole 331, and the eccentric shaft 32 is inserted into the connecting hole 331. There is a gap between the upper and lower sides of the eccentric shaft 32 and the inner wall of the connecting hole 331. For details, see Figure 3 、 Figure 4 and Figure 6 , the strip bag clamping mechanism 2 clamps and fixes the strip bag that has passed the weighing, and then the rotating driving member 31 drives the eccentric shaft 32 to rotate. Since there is a gap between the upper and lower sides of the eccentric shaft 32 and the inner wall of the connecting hole 331, the eccentric shaft 32 can drive the connecting member 33, the strip bag clamping mechanism 2 and the like to move forward and backward as a whole during the rotation process, while avoiding unnecessary up and down movement. The structure is reasonable and effective.

[0032] Further, in this embodiment, a rolling bearing 34 is also provided at one end of the eccentric shaft 32 located in the connecting hole 331. By providing the rolling bearing 34, the frictional resistance between the eccentric shaft 32 and the connecting member 33 can be reduced, making the material leveling process smoother and reducing the wear between components.

[0033] As a preferred embodiment, the rotary drive member 31 is a servo motor. The servo motor has characteristics such as fast response speed and high motion accuracy, and is suitable for quickly and intermittently driving the eccentric shaft 32 to rotate. Of course, in other embodiments, a general motor, a pneumatic motor, etc. can also be used as the rotary drive member 31.

[0034] Further, in this embodiment, a material leveling guide assembly 4 is provided between the bracket 1 and the strip package clamping mechanism 2. The material leveling guide assembly 4 can provide a guiding effect for the reciprocating movement of the strip package clamping mechanism 2, making the movement of the strip package clamping mechanism 2 more stable and smooth, and avoiding deviation.

[0035] Specifically, refer to Figures 3 to Figure 5 , as a preferred embodiment, the material leveling guide assembly 4 includes a first slide rail 41 and a first slider 42 that cooperates with the first slide rail 41. The first slide rail 41 is provided at both ends of the bracket 1, and the first slider 42 is provided at both ends of the strip package clamping mechanism 2, with good symmetry and balance, which is beneficial to ensuring the synchronous movement of both ends of the strip package clamping mechanism 2. Of course, in other embodiments, the material leveling guide assembly 4 can also be structures such as a guide rail and a guide sleeve, a guide rail and a pulley, etc., which will not be elaborated here.

[0036] Further, in this embodiment, the strip package clamping mechanism 2 includes a sliding seat 21, mounting beams 22 provided on both sides of the sliding seat 21, and a clamping drive member 23 for driving the sliding seat 21 to reciprocate. A plurality of fixed clamping members 24 are provided between the two mounting beams 22, and a plurality of movable clamping members 25 are provided on the sliding seat 21. The plurality of movable clamping members 25 are arranged in one-to-one correspondence with the plurality of fixed clamping members 24. The clamping drive member 23 is provided on the mounting beam 22, and the material leveling mechanism 3 is connected to the mounting beam 22 (specifically, the connecting member 33 is connected to the mounting beam 22). After the strip package with qualified weight is conveyed to the fixed clamping member 24, the clamping drive member 23 drives the sliding seat 21 and the movable clamping members 25 thereon to move, and the movable clamping members 25 approach the corresponding fixed clamping members 24, thereby clamping the strip package. The structure is simple and the clamping efficiency is high. After the strip package is clamped and fixed, the connecting member 33 drives the mounting beam 22, the clamping drive member 23, the sliding seat 21, etc. to vibrate quickly and orderly along the length direction of the strip package for material leveling. After the material leveling is completed, the clamping drive member 23 drives the sliding seat 21 and the movable clamping members 25 thereon to move, and the movable clamping members 25 move away from the corresponding fixed clamping members 24, thereby loosening the strip package. The strip package is transferred to the gathering and conveying mechanism 6, and so on in a cycle.

[0037] Furthermore, in this embodiment, a clamping and guiding assembly is provided between the sliding seat 21 and the mounting beam 22. The clamping and guiding assembly can provide a guiding function for the reciprocating movement of the sliding seat 21 and the movable clamping member 25, making the movement of the sliding seat 21 and the movable clamping member 25 smoother and more stable, and avoiding deviation.

[0038] As a preferred embodiment, the clamping and guiding assembly includes a second slide rail 26 and a second slider 27 that cooperates with the second slide rail 26. The second slide rail 26 is provided at both ends of the sliding seat 21, and the second slide rail 26 is provided at both ends of the mounting beam 22, with good symmetry and balance, which is beneficial to ensuring the stability of the movement of the sliding seat 21. Of course, in other embodiments, the clamping and guiding assembly can also be structures such as a guide rail and a guide sleeve, a guide rail and a pulley, etc., which will not be elaborated here.
