[0038] Please see Figure 1 This utility model provides a fine auxiliary material loading and unloading device for cigarette production, including: a full material tray storage rack 1, an empty tray storage rack 2, an auxiliary material tray moving device 5, an auxiliary material gripping mechanism 6, and a material unloading and conveying device 4. The structure will be described in detail below.

[0039] A full material tray storage rack 1 is used to store auxiliary material trays 8. The full material tray storage rack 1 is set on the base plate 3, and the auxiliary material trays 8 containing auxiliary materials are stacked vertically in the full material tray storage rack 1.

[0040] Specifically, please refer to Figure 2 The full material tray storage rack 1 includes a first table 1a, a first enclosure 1d, a blocking mechanism, and a first table leg 1b. The first table 1a is mounted on the base plate 3 via the first table leg 1b. The first table 1a has a first through hole 1c for the auxiliary material tray 8 to pass through. The first enclosure 1d is provided around the first through hole 1c. The first enclosure 1d is composed of four L-shaped steel frames, and the length and width of the space enclosed by the first enclosure 1d match the length and width of the auxiliary material tray 8, thereby preventing the auxiliary material tray 8 from sliding in the first enclosure 1d and causing inaccurate positioning. A blocking mechanism is provided outside the first through hole 1c to prevent the auxiliary material tray 8 from falling. Preferably, there are two blocking mechanisms.

[0041] In some embodiments, the blocking mechanism includes a first cylinder 1e and a stop block 1f, the first cylinder 1e is provided with a stop block 1f at its push-out end, and the auxiliary material tray 8 is provided with a groove 8a for the stop block 1f to extend into.

[0042] Since the auxiliary material tray 8 is stacked vertically in the full material tray storage rack 1, the cylinder 1e is in the extended state when the bottom auxiliary material tray 8 is not removed, so that the stop block 1f extends into the groove 8a on both sides of the auxiliary material tray 8, thereby preventing the auxiliary material tray 8 from falling.

[0043] Empty tray storage rack 2, which is used to store empty auxiliary material trays 8, is set on the base plate 3;

[0044] Specifically, please refer to Figure 3 The empty tray storage rack 2 includes a second tabletop 2a, a second enclosure 2d, and a second table leg 2c. The second tabletop 2a is mounted on the base plate 3 via the second table leg 2c. The second tabletop 2a has a second through hole 2b through which the auxiliary material tray 8 passes. Wedge-shaped blocks 2f are provided on both sides of the second through hole 2b. A grating 2e is also provided on the upper part of the second enclosure 2d. When the stored auxiliary material tray 8 reaches the grating 2e, it indicates that the empty tray storage rack 2 is full and an alarm is triggered.

[0045] More specifically, such as Figure 4As shown, the bottom of the wedge-shaped stop 2f is provided with a protrusion, which makes the wedge-shaped stop 2f only able to be pushed upward and not downward. When the empty auxiliary material tray 8 needs to be stored, the auxiliary material tray 8 passes upward through the second through hole 2b and pushes the wedge-shaped stop 2f upward. When the two sides of the auxiliary material tray 8 are separated from the wedge-shaped stop 2f, the wedge-shaped stop 2f returns to its original horizontal position. Preferably, in order to make the wedge-shaped stop 2f more reliably return to its original position, a torsion spring can be provided on the rotation shaft of the wedge-shaped stop 2f.

[0046] The auxiliary material tray moving device 5 is located below the full material tray storage rack 1. The auxiliary material tray moving device 5 is driven by the driving mechanism 7 so that the auxiliary material tray moving device 5 can reciprocate at the bottom of both the full material tray storage rack 1 and the empty tray storage rack 2.

[0047] Please see Figure 6 In some embodiments, the drive mechanism 7 includes two pulleys 7c, a servo motor 7a, and a belt 7b. The belt 7b is wound between the two pulleys 7c, and one of the pulleys 7c is connected to the output end of the servo motor 7a. The belt 7b is connected to the auxiliary material tray moving device 5. Of course, this application is not limited to this driving method. The bottom plate 3 is provided with side end plates 3a at both ends. Each side end plate 3a is provided with a proximity switch 3c. The proximity switch 3c is used to drive the servo motor 7a to rotate in the opposite direction when the auxiliary material tray moving device 5 approaches. A guide rod 3b is also connected between the two side end plates 3a, so that the movement of the auxiliary material tray moving device 5 is more stable.

[0048] Please see Figure 7 The auxiliary material tray moving device 5 includes an upper base plate 5a and a lower base plate 5c. The upper base plate 5a and the lower base plate 5c are connected by a connecting column 5h. A push plate 5e is provided on the upper surface of the upper base plate 5a. A second cylinder 5g is provided on the lower base plate 5c. The push-out end of the second cylinder 5g is connected to the push plate 5e, thereby realizing the pushing of the push plate 5e.

[0049] The upper surface of the upper base plate 5a is provided with a limiting protrusion 5f, which is located on the outer periphery of the push plate 5e, thereby restricting the movement of the auxiliary material tray 8. Guide sleeves 5b are provided on both sides of the bottom surface of the upper base plate 5a, and the guide sleeves 5b are inserted through the guide rod 3b. A belt connecting seat 5d is also provided on one side of the bottom surface of the upper base plate 5a, and the belt connecting seat 5d is connected to the belt 7b.

[0050] The auxiliary material gripping mechanism 6 is used to grip the auxiliary material in the auxiliary material tray 8 located on the auxiliary material tray moving device 5. The auxiliary material gripping mechanism 6 is set on the base plate 3 and located between the full material tray storage rack 1 and the empty tray storage rack 2.

[0051] For details, please refer to Figure 5The auxiliary material gripping mechanism 6 includes a cross-shaped linear module 6a, a pneumatic finger cylinder 6c, and a clamping plate 6d. The cross-shaped linear module 6a and the pneumatic finger cylinder 6c are existing technologies, and will not be described in detail in this utility model. The cross-shaped linear module 6a is mounted on the base plate 3 via a support column 6e. The pneumatic finger cylinder 6c is mounted on the slide table 6b of the cross-shaped linear module 6a. The clamping plates 6d are mounted on the two clamping ends of the pneumatic finger cylinder 6c. The clamping area between the clamping plates 6d is located in the same vertical plane as the conveying surface of the unloading conveying device 4.

[0052] The feeding conveying device 4 is used to convey the auxiliary materials gripped by the auxiliary material gripping mechanism 6. The feeding conveying device 4 is located on one side of the base plate 3 and close to the auxiliary material gripping mechanism 6.

[0053] The working process of this utility model is as follows:

[0054] S1. Retrieving and loading the tray: The drive mechanism 7 drives the auxiliary tray moving device 5 to move forward to directly below the full tray storage rack 1. At this time, the second cylinder 5g of the auxiliary tray moving device 5 pushes upward and the first cylinder 1e retracts, so that the auxiliary tray 8 located at the bottom of the full tray storage rack 1 falls on the push plate 5e of the auxiliary tray moving device 5 to complete the tray retrieval action. Then the first cylinder 1e pushes out so that the stop block 1f blocks the auxiliary tray 8 in the full tray storage rack 1.

[0055] S2, Unloading: The auxiliary material tray moving device 5 moves backward. When the auxiliary material in front of the auxiliary material tray 8 is just below the clamping plate 6d, the movement mode of the auxiliary material tray moving device 5 is intermittent. Through the cooperation of the cross linear module 6a and the pneumatic finger cylinder 6c, the auxiliary material in the auxiliary material tray 8 is grabbed onto the unloading conveyor device 4.

[0056] S3. Empty tray storage: When the auxiliary materials in the auxiliary material tray 8 are completely grabbed, the auxiliary material tray moving device 5 continues to move backward to directly below the empty tray storage rack 2. The second cylinder 5g of the auxiliary material tray moving device 5 pushes upward again, so that the push plate 5e pushes the empty auxiliary material tray 8 into the empty tray storage rack 2. When the second cylinder 5g falls back, the auxiliary material tray 8 is blocked by the wedge-shaped stop 2f. When the auxiliary material tray 8 is stacked at the grating, an alarm is sounded.

[0057] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims. Besides modifications and improvements to the components or layout, other uses will be apparent to those skilled in the art.
