Description

Technical Field

[0001] The present invention relates to the field of cigarette performance detection, and more particularly to an automated batch cigarette material filling value measuring device. Background Art

[0002] The filling value of tobacco materials reflects the pressure-bearing performance of tobacco cuts, stems, or flakes. For example, testing the filling value of cut tobacco involves placing a certain mass of cut tobacco in a measuring cylinder and measuring the volume it maintains under a certain pressure for a certain period of time. This yields the filling value.

[0003] Existing methods for measuring cigarette material filling values ​​require manually weighing a certain mass of cigarette material and then filling it into a measuring cylinder for measurement. Each measurement requires a series of steps: weighing, filling the measuring cylinder, starting the instrument, waiting for measurement, and removing the test material from the measuring cylinder. In practice, multiple groups of test samples (up to 30 per group) often need to be measured, resulting in high labor intensity and low efficiency.

[0004] Therefore, how to provide a device that can effectively improve the measurement efficiency of cigarette material filling value and reduce work intensity has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

DETAILED DESCRIPTION

[0035] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention.

[0036] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0037] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0038] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0039] like Figure 1 As shown, the automated batch cigarette material filling value measuring device disclosed herein includes a hopper conveying device 1 , a hopper transferring device, a material pressing detection device and a material unloading device 105 .

[0040] The hopper conveyor device 1 is provided with multiple hoppers 01 filled with tobacco materials. The hopper conveyor device 1 can be, for example, a conveyor belt. The tobacco materials typically include shredded tobacco, cut stems, and flakes. The weight of the tobacco materials in the hoppers 01 can be determined during the filling process.

[0041] The hopper transfer device includes a hopper clamping unit 2 and a hopper clamping unit rotating mechanism 3. The hopper clamping unit 2 is used to clamp a single hopper 01 on the hopper conveyor device 1, which is the hopper to be tested. The hopper clamping unit 2 can be, for example, a robotic arm. The hopper clamping unit rotating mechanism 3 is used to rotate the hopper clamping unit 2. The hopper clamping unit rotating mechanism 3 can move the hopper clamping unit 2 between the hopper conveyor device 1 and the material pressure detection device, thereby transferring the hopper clamped by the hopper clamping unit 2 on the material conveyor device 1 to the material pressure detection device.

[0042] The material pressure detection device includes a hopper support platform 4, a pressure mechanism, and a height detection mechanism 7. The hopper support platform 4 can be used to support the hopper to be tested, which is released by the hopper clamping unit 2. The pressure mechanism includes a pressure plate 5 and a pressure plate lifting assembly 6. The pressure plate lifting assembly 6 can be used to release the pressure plate 5 so that it applies pressure to the cigarette material in the hopper to be tested, and can also be used to pull the pressure plate 5 so that it moves away from the cigarette material in the hopper to be tested. The pressure plate lifting assembly 6 is a structure that can drive the pressure plate 5 to move in a direction closer to or away from the hopper support platform 4, such as a cylinder. The height detection mechanism 7 can be used to detect the height change of the cigarette material in the hopper to be tested after being pressed. The height detection mechanism 7 can detect the height change of the cigarette material in the hopper to be tested, or it can detect the height change of the pressure plate 5 before and after applying pressure to the cigarette material in the hopper to be tested. The height detection mechanism 7 can be, for example, a position sensor, a height sensor, or a displacement sensor.

[0043] The unloading device 105 can be used to unload the hopper on the hopper support platform 4. The unloading device 105 can push the hopper on the hopper support platform 4 away from the hopper support platform 4. The unloading device 105 can be, for example, a motor.

[0044] When the automated batch cigarette material filling value measuring device disclosed herein is in use, the hopper conveying device 1 conveys the hopper 01 to the working area of ​​the hopper clamping unit 2. The hopper clamping unit 2 clamps the hopper to be measured, and transfers the hopper clamping unit 2 and the clamped hopper to be measured to the hopper support platform 4 through the hopper clamping unit rotating mechanism 3. The pressure plate lifting assembly 6 drives the pressure plate 5 to apply pressure to the cigarette material in the hopper to be measured, and drives the pressure plate 5 to leave the cigarette material in the hopper to be measured after maintaining the pressure for a period of time. The height detection mechanism 7 detects the height difference of the cigarette material before and after the pressure is applied, and obtains the height change of the cigarette material after being pressed. The filling value of the cigarette material can be obtained from the weight parameters of the cigarette material in the hopper to be measured and the height change of the cigarette material after being pressed. After completing the current cigarette material filling value detection, the unloading device 105 unloads the hopper on the hopper support platform 4. As the hopper clamping unit rotating mechanism 3 drives the hopper clamping unit 2 to rotate to the position where it clamps the hopper 01 on the hopper conveying device 1, the next cigarette material filling value detection begins. Those skilled in the art can determine the number of measurement cycles of the cigarette material filling value device based on the required number of filling values ​​to be detected.

[0045] The automated batch cigarette material filling value measuring device disclosed herein realizes automated detection of cigarette material filling values ​​through a hopper conveying device 1, a hopper transfer device, and a material pressing detection device, and unloads the measured cigarette material through a unloading device 105, which can effectively improve the measurement efficiency of cigarette material filling values ​​and reduce work intensity.

[0046] In one embodiment of the automated batch cigarette material filling value measuring device disclosed herein, the hopper clamping unit 2 includes an electromagnetic component. In specific implementations, the hopper clamping unit 2 may also include a connecting arm and other structures. The hopper clamping unit 2 conveniently clamps the hopper 01 on the hopper conveying device 1 through electromagnetic attraction.

[0047] In one embodiment of the automated batch cigarette material filling value measuring device disclosed herein, the hopper support platform 4 includes a support platform fixed portion 41 and a support platform movable portion 42. The hopper to be measured on the hopper support platform 4 is supported on the support platform fixed portion 41 and the support platform movable portion 42.

[0048] The unloading device 105 is connected to the support platform moving portion 42 to drive the support platform moving portion 42 to move relative to the support platform fixed portion 41, so that the hopper to be tested on the hopper support platform 4 can leave the hopper support platform 4 through the gap between the support platform moving portion 42 and the support platform fixed portion 41. When the support platform moving portion 42 moves relative to the support platform fixed portion 41, a gap is formed between the two, and the hopper on the hopper support platform 4 can fall into the gap between the support platform fixed portion 41 and the support platform moving portion 42, thereby leaving the hopper support platform 4.

[0049] Furthermore, the automatic batch cigarette material filling value measuring device further comprises a base 8. The base 8 is provided with a discharge hole 80.

[0050] The fixed portion 41 of the support platform is fixedly connected to the base 8, and the fixed connection between the two can be achieved by welding or bolting. The movable portion 42 of the support platform slides with the base 8, and the sliding connection between the two can be achieved by slide rails. After the movable portion 42 moves relative to the fixed portion 41 of the support platform, the gap formed between the movable portion 42 and the fixed portion 41 of the support platform corresponds to the discharge hole 80, so that the hopper to be measured on the hopper support platform 4 can be separated from the automated batch cigarette material filling value measuring equipment through the gap between the movable portion 42 and the fixed portion 41 of the support platform and the discharge hole 80.

[0051] In one embodiment of the automated batch cigarette material filling value measuring device disclosed herein, in order to more conveniently control the pressure plate 5 to apply pressure to the cigarette material in the hopper to be measured, the pressure plate lifting assembly 6 includes a pull wire 61, a pull wire wheel 62 and a pull wire wheel control unit 63.

[0052] One end of the pull wire 61 is fixedly connected to the pressure plate 5, and the other end of the pull wire 61 is fixedly connected to the pull wheel 62. The pull wheel control unit 63 can be used to control the retraction and extension of the pull wheel 62. The pull wheel control unit 63 can be, for example, an electromagnetic brake.

[0053] In one embodiment of the automatic batch cigarette material filling value measuring device disclosed herein, the pressing material detection device further includes a pressure timing unit 9. The pressure timing unit 9 can be used to time the pressing time of the pressing plate 5.

[0054] In a specific implementation, the timing start and stop of the pressure timing unit 9 can be linked to the pressure plate lifting assembly 6. For example, when the pulley control unit 63 controls the pulley 62 to pay out the line (the payout time is usually as short as less than 0.5s and can be ignored), the pressure timing unit 9 can start timing; when the pulley control unit 63 controls the pulley 62 to reel in the line, the pressure timing unit 9 stops timing.

[0055] In one embodiment of the automated batch cigarette material filling value measuring device disclosed herein, the height detection mechanism 7 includes a height detection rod 71 and a height detection sensor 72. The height detection rod 71 is fixedly connected to the pressure plate 5. The height detection sensor 72 is configured to detect the change in height of the height detection rod 71 after the pressure plate 5 contacts the cigarette material in the hopper to be measured. The height detection sensor 72 can be, for example, a laser sensor. This structure of the height detection mechanism 7 provides high detection sensitivity and accurate detection data.

[0056] In one embodiment of the automated batch cigarette material filling value measurement device disclosed herein, the pressure mechanism further includes a counterweight 101. Counterweight 101 is mounted on the pressure plate 5 to vary the force applied by the pressure plate 5 to the cigarette material in the hopper to be measured. Counterweight 101 is removable and replaceable, enabling measurement of the filling values ​​of different types of cigarette material.

[0057] In one embodiment of the automated batch cigarette material filling value measuring device disclosed herein, the automated batch cigarette material filling value measuring device further includes a weighing device. The weighing device includes a weighing unit 102. The weighing unit 102 is located between the hopper conveying device 1 and the hopper transfer device and is used to weigh the weight of the hopper to be measured, which is conveyed by the hopper conveying device 1. The weighing unit 102 can weigh the total weight of the hopper and the cigarette material therein. Since the weight of the hopper is known in advance, the weight of the cigarette material within the hopper can be conveniently determined.

[0058] Furthermore, the weighing device also includes a support frame 103 and a support frame lifting mechanism 104 .

[0059] The support frame 103 is located between the hopper conveying device 1 and the hopper transfer device, and the support frame 103 is arranged around the weighing unit 102 .

[0060] The support frame lifting mechanism 104 can be used to drive the support frame 103 to move. The support frame lifting mechanism 104 can be, for example, a motor.

[0061] The support frame 103 has a supporting position and a weighing position.

[0062] When the support frame 103 is in the supporting position, the weighing unit 102 is located in the support frame 103. The hopper to be measured conveyed by the hopper conveying device 1 is supported on the support frame 103. When the support frame 103 is in the supporting position, the hopper to be measured is supported on the support frame 103 and does not contact the weighing unit 102.

[0063] When support frame 103 is in the weighing position, weighing unit 102 is positioned above support frame 103. The hopper to be measured, delivered by hopper conveyor 1, is supported on weighing unit 102. Hopper clamping unit 2 clamps the hopper to be measured on weighing unit 102 when support frame 103 is in the weighing position. When support frame 103 is in the weighing position, the hopper to be measured is supported on weighing unit 102 and does not contact support frame 103.

[0064] During implementation, the support frame 103 is first positioned in the supporting position, and the hopper to be tested, delivered by the hopper conveyor 1, is supported on the support frame 103. The support frame lifting mechanism 104 then drives the support frame 103 toward the weighing unit 102 until the hopper to be tested is fully supported on the weighing unit 102. After the weight of the hopper to be tested is measured, the hopper clamping unit 2 clamps the hopper to be tested on the weighing unit 102. Once the hopper to be tested leaves the weighing unit 102, the support frame lifting mechanism 104 drives the support frame 103 away from the weighing unit 102, allowing the support frame 103 to support the hopper to be tested for the next cigarette material filling value.

[0065] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention.
