Description

Technical Field

[0001] This invention relates to the field of tobacco box conveying technology, and in particular to a tobacco box turning conveying device. Background Technology

[0002] In the processing and handling of tobacco products such as cigarette sheets, shredded tobacco, stems, expanded tobacco, and cigarette packs, tobacco boxes are often used to store the materials. Therefore, the transfer of tobacco boxes is an important process.

[0003] However, the sizes of the cigarette boxes are not the same, and the cigarette boxes inevitably have to turn during the conveying process. At present, most of the cigarette box turning is driven by a frustum-shaped roller. Small cigarette boxes can turn smoothly, but large cigarette boxes sometimes get stuck when turning, requiring manual pushing of the cigarette box forward. This not only wastes manpower, but if it is not discovered in time, it will cause the entire cigarette box conveying process to stop, affecting the efficiency of cigarette box conveying. Summary of the Invention

[0004] The purpose of this invention is to provide a cigarette box turning conveyor to solve the problem mentioned in the background art that cigarette boxes inevitably need to turn during the conveying process. Currently, most cigarette box turning is driven by a frustum-shaped roller. Small cigarette boxes can turn smoothly, but large cigarette boxes sometimes get stuck when turning, requiring manual pushing of the cigarette box forward. Moreover, if it is not detected in time, it will cause the entire cigarette box conveying process to stop, affecting the cigarette box conveying efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A cigarette box turning conveyor includes:

[0007] A frame, on which a first support beam and a second support beam are arranged opposite to each other, and a sensor is arranged on the first support beam;

[0008] A conveying mechanism includes a roller, a drive shaft, a first one-way bearing, a second one-way bearing, and a pulley. The roller has a frustum structure and a hollow interior. The drive shaft passes through the interior of the roller. The inner ring of the first one-way bearing is fitted onto the large end face of the roller. The pulley is fitted onto the outer ring of the first one-way bearing. The roller is rotatably connected to a first support beam. The inner ring of the second one-way bearing is fitted onto the drive shaft. The small end face of the roller is fitted onto the outer ring of the second one-way bearing. The drive shaft is rotatably connected to a second support beam. The locking direction of the first one-way bearing is opposite to that of the second one-way bearing.

[0009] A constant speed belt, which is driven by a constant speed motor, is engaged with the drive shaft.

[0010] A support frame is provided, on which a variable speed motor and a frequency converter are mounted. The frequency converter is electrically connected to the variable speed motor and the sensor. A variable speed belt is provided at the output end of the variable speed motor, and the variable speed belt is driven by the pulley.

[0011] Optionally, a transition conveyor belt is provided on the frame, and the transition conveyor belt is driven by the constant speed motor.

[0012] Optionally, the pulley has a limiting groove along its circumference, and the speed belt is embedded in the limiting groove.

[0013] Optionally, the pulley has a first toothed groove along its circumference, the inner side of the variable speed belt has a first tooth that mates with the first toothed groove, and the output end of the variable speed motor has a drive pulley, the drive pulley has a second toothed groove along its circumference that mates with the first tooth.

[0014] Optionally, the first support beam and the second support beam are arranged in parallel.

[0015] Optionally, the height of the first support beam is greater than or equal to the height of the second support beam.

[0016] The beneficial effects of this invention are:

[0017] The cigarette box turning conveyor device provided by this invention, by incorporating a first one-way bearing, a second one-way bearing, and a variable-speed motor, increases the speed difference between the inner and outer sides of the cigarette box, preventing the large cigarette box from jamming. When the large cigarette box turns, the sensor can detect it in time and quickly transmit the signal to the frequency converter. The frequency converter controls the speed of the variable-speed motor, which drives the variable-speed belt. At this time, the speed of the variable-speed belt is significantly higher than that of the constant-speed belt. The variable-speed belt drives the pulley to rotate counterclockwise, and the pulley drives the roller to rotate counterclockwise. At this time, both the outer and inner rings of the second one-way bearing rotate counterclockwise. The outer ring of the second one-way bearing rotates at a higher speed than the inner ring, so the inner ring of the second one-way bearing rotates clockwise relative to the outer ring. Therefore, the second one-way bearing transmits almost no torque to the drive shaft, avoiding energy waste. This cigarette box turning conveyor device, by increasing the speed difference between the inner and outer sides of the cigarette box, can prevent the large cigarette box from sometimes jamming when turning, eliminating the need for manual pushing of the cigarette box forward, reducing stagnation in the entire cigarette box conveying process, and ensuring the efficiency of cigarette box conveying.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 3 As shown, the present invention provides a cigarette box turning conveyor device, including a frame 100, a conveying mechanism 200, a constant speed belt 300, and a support frame 400.

[0035] The frame 100 has a first support beam 110 and a second support beam 120 arranged opposite each other. A sensor 130 is mounted on the first support beam 110. The conveying mechanism 200 includes a roller 210, a drive shaft 220, a first one-way bearing 230, a second one-way bearing 240, and a pulley 250. The roller 210 has a frustum structure and a hollow interior. The drive shaft 220 passes through the interior of the roller 210. The inner ring of the first one-way bearing 230 is fitted onto the large end face of the roller 210, and the pulley 250 is fitted onto the outer ring of the first one-way bearing 230. The roller 210 is rotatably connected to the first support beam 110. The second one-way bearing 240... The inner ring of the roller 210 is fitted onto the drive shaft 220, and the small end face of the roller 210 is fitted onto the outer ring of the second one-way bearing 240. The drive shaft 220 is rotatably connected to the second support beam 120. The locking direction of the first one-way bearing 230 is opposite to that of the second one-way bearing 240. The constant speed belt 300 is driven by the drive shaft 220. The constant speed belt 300 is driven by the constant speed motor. The support frame 400 is equipped with a variable speed motor 500 and a frequency converter 600. The frequency converter 600 is electrically connected to the variable speed motor 500 and the sensor 130. The output end of the variable speed motor 500 is equipped with a variable speed belt 510, which is driven by the pulley 250.

[0036] The inner ring of the second one-way bearing 240 rotates clockwise relative to the outer ring and locks counterclockwise. The inner ring of the first one-way bearing 230 rotates counterclockwise relative to the outer ring and locks clockwise. In this text, clockwise and counterclockwise rotation are based on the view from the large end face of the roller 210 to the small end face. Therefore, the drive shaft 220 can drive the roller 210 to rotate counterclockwise through the counterclockwise locking characteristic of the second one-way bearing 240. The large end face of the roller 210 is fitted with the first one-way bearing 230, whose inner ring locks clockwise and rotates counterclockwise. The first one-way bearing 230 is fitted with a pulley 250, which can drive the roller 210 to rotate counterclockwise through the clockwise locking characteristic of the first one-way bearing 230.

[0037] The cigarette box turning conveyor device provided by this invention, by setting a first one-way bearing 230, a second one-way bearing 240, and a variable speed motor 500, can increase the speed difference between the inner and outer sides of the cigarette box, preventing the large cigarette box from getting stuck. When the large cigarette box turns, the sensor 130 can detect the large cigarette box in time and quickly transmit the signal to the frequency converter 600. The frequency converter 600 controls the speed of the variable speed motor 500, which drives the variable speed belt 510 to move. At this time, the speed of the variable speed belt 510 is significantly higher than that of the constant speed belt 300. The variable speed belt 510 drives the pulley 250 to rotate counterclockwise, and the pulley 250 drives the roller 210 to rotate counterclockwise. At this time, both the outer and inner rings of the second one-way bearing 240 rotate counterclockwise. The outer ring of the second one-way bearing 240 rotates at a higher speed than the inner ring, so the inner ring of the second one-way bearing 240 rotates clockwise relative to the outer ring. Therefore, the second one-way bearing 240 hardly transmits torque to the drive shaft 220, avoiding energy waste. This cigarette box turning conveyor device, by increasing the speed difference between the inside and outside of the cigarette box, can prevent large cigarette boxes from getting stuck when turning, eliminating the need for manual pushing of the cigarette box forward, reducing stagnation in the entire cigarette box conveying process, and ensuring the efficiency of cigarette box conveying.

[0038] In some embodiments, a transition conveyor belt 140 is provided on the frame 100. The transition conveyor belt 140 is driven by a constant speed motor and conveys the tobacco box to the roller 210.

[0039] In some embodiments, the pulley 250 has a limiting groove 251 along its circumference, and the speed belt 510 is embedded in the limiting groove 251. By setting the limiting groove 251, the speed belt 510 can be prevented from disengaging from the pulley 250 during the rotation of the pulley 250, thus ensuring the reliability of the speed belt 510 driving the pulley 250.

[0040] Optionally, the pulley 250 has a first toothed groove along its circumference, the inner side of the transmission belt 510 has a first tooth that mates with the first toothed groove, and the output end of the transmission motor 500 is provided with a drive pulley, the drive pulley has a second toothed groove along its circumference that mates with the first toothed groove. With the above structure, slippage of the transmission belt 510 can be avoided, and the stability of the transmission belt 510 drive can be guaranteed.

[0041] To ensure the stability of the first support beam 110 and the second support beam 120 in supporting the conveying mechanism 200, the first support beam 110 and the second support beam 120 are arranged in parallel. Preferably, the height of the first support beam 110 is greater than or equal to the height of the second support beam 120, thereby reducing the risk of the smoke box colliding with the first support beam 110 under inertia.

[0042] When the tobacco box turns, on the one hand, it is necessary to ensure that the speed of the side of the tobacco box near the outer circumference is greater than that of the side near the inner circumference, that is, there must be a speed difference between the inner and outer sides of the tobacco box. On the other hand, in order to counteract the centrifugal force, the height of the outer side of the tobacco box must be higher than the height of the inner side of the tobacco box. Since the roller 210 has a frustum structure, the circumference of the large end face of the roller 210 is greater than that of the small end face. The variable speed motor 500 can drive the variable speed belt 510 so that the speed of the variable speed belt 510 is significantly higher than that of the constant speed belt 300. Therefore, the above two requirements are met.

[0043] It should be noted that the specific model and specifications of the above-mentioned electrical appliances can be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here. Furthermore, the power supply and principle of the electrical appliances are clear to those skilled in the art, and will not be described in detail here.

[0044] The working principle of the cigarette box turning conveyor provided by this invention is as follows:

[0045] When the small cigarette box turns, the variable speed motor 500 does not work, and the constant speed belt 300 drives the transmission shaft 220 to rotate counterclockwise. The transmission shaft 220 drives the inner ring of the second one-way bearing 240 to rotate counterclockwise. The inner ring and outer ring of the second one-way bearing 240 are locked, thereby driving the roller 210 to rotate counterclockwise, which in turn transmits the cigarette box. At this time, the roller 210 drives the inner ring of the first one-way bearing 230 to rotate counterclockwise. The inner ring of the first one-way bearing 230 rotates counterclockwise relative to the outer ring. Therefore, the first one-way bearing 230 hardly transmits torque to the pulley 250, the pulley 250 hardly rotates, and there is almost no force between the pulley 250 and the variable speed belt 510, thus avoiding energy waste.

[0046] When the large smoke box turns, to avoid jamming, the speed difference between the inside and outside of the smoke box needs to be increased. Sensor 130 detects the large smoke box and quickly transmits the signal to inverter 600. Inverter 600 controls the speed of variable speed motor 500. Variable speed motor 500 drives variable speed belt 510. At this time, the speed of variable speed belt 510 is significantly higher than that of constant speed belt 300. Variable speed belt 510 drives pulley 250 to rotate counterclockwise. Pulley 250 drives the outer ring of first one-way roller 210 to rotate counterclockwise. The outer and inner rings of first one-way bearing 230 are locked, thus driving roller 210 to rotate counterclockwise. At this time, both the outer and inner rings of second one-way bearing 240 rotate counterclockwise. The outer ring of second one-way bearing 240 rotates faster than the inner ring, so the inner ring of second one-way bearing 240 rotates clockwise relative to the outer ring. Therefore, second one-way bearing 240 hardly transmits torque to drive shaft 220, avoiding energy waste.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
