Description

Technical Field

[0001] The utility model relates to the technical field of tobacco leaf feeding, in particular to raw tobacco homogenizing feeding equipment with adaptability to tobacco frames of multiple specifications. Background Art

[0002] Currently, blended tobacco leaves are primarily threshed on the front-end leaf laying line, where different grades of tobacco leaves are manually fed in according to the formulated blend. Once the tobacco leaves are fed according to the formulated blend, they are fed into the subsequent production lines. The uniformity of the blend depends largely on the operator's spread and speed. This method requires high levels of production management and staff expertise. Human interference can hinder the accuracy of the blend, preventing homogeneous feeding and hindering chemically uniform blending. Leaf laying is the first and most critical step in industrial blending. Failure to adhere to the defined blend directly impacts the quality of the finished tobacco leaves, and the blending process plans made previously are rendered meaningless. Furthermore, current tobacco loading racks come in varying sizes, complicating the feeding process. Therefore, developing a multi-rack, homogenized raw tobacco loading device is crucial to enhance the automation of raw tobacco automatic leaf laying, adapt to multiple rack conditions, and improve the homogenization of tobacco blend production.

Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0022] The features and performance of the present invention are further described in detail below with reference to the embodiments.

[0023] See also Figure 1A raw tobacco homogenizing feeding device with adaptability to tobacco frames of multiple specifications includes a truss 1, on which a pair of transverse guide rails 2 are provided, on which longitudinal guide rails 3 are slidably provided, on which vertical guide rails 4 that slide up and down are provided, and below which a grabbing manipulator 5 is provided. The grabbing manipulator 5 is adjusted in position by the action of the transverse guide rails 2, the longitudinal guide rails 3, and the vertical guide rails 4; below which a weighing belt 6 is provided; and below which an adjustment slide 7 is provided. The adjustment slide 7 is used to carry the tobacco frame and adjust its position, and is provided with a sensor. The adjustment slide 7 identifies the specification type of the tobacco frame through the sensor and moves the tobacco frame to the side of the weighing belt 6. The grabbing manipulator 5 grabs and spreads the tobacco leaves, and cooperates with the weighing belt 6 to freely adjust the grabbing amount of tobacco leaves according to the weight of the material input, thereby achieving the purpose of homogenizing the feeding.

[0024] Adjustment slides 7 are installed on both sides of the weighing belt 6, simultaneously supporting the tobacco frames for feeding. The gripping robot 5 loads tobacco from both sides, saving space and ensuring a continuous and uninterrupted supply of raw tobacco, thus enhancing loading efficiency. This improves space utilization and operational efficiency. The height of the adjustment slides 7 is higher than the legs of the tobacco frames. After the tobacco frames are placed on the adjustment slides 7, they adjust the working position.

[0025] A conveyor belt 8 is also provided under the weighing belt 6. The grabbing robot 5 moves through the transverse guide rails 2, longitudinal guide rails 3 and vertical guide rails 4 to grab the work materials in the cigarette frame, and places the work materials on the weighing belt 6 for weighing, and is then transported by the conveyor belt 8. The weighing belt 6 is provided above the conveyor belt 8, and its length is shorter than that of the conveyor belt 8.

[0026] The cooperation between the weighing belt 6 and the grabbing manipulator 5 enables the precise control of the tobacco material and achieves homogeneous production.

[0027] The gripping robot 5, transverse guide rails 2, longitudinal guide rails 3, and vertical guide rails 4 are controlled by a PLC controller. The weighing belt 6 and the speed of the conveyor belt 8 are also controlled by the PLC controller. The PLC controller is a Siemens controller, and its start and stop are linked to the cutting line through I / O signal connections. The PLC controller exchanges data via S7 communication or Modbus TCP.

[0028] The cigarette frame includes an A-type frame 9 and a B-type frame 10. The specifications of the A-type frame 9 are 1855mm long × 1604mm wide × 1485mm high, and the specifications of the B-type frame 10 are 1880mm long × 1160mm wide × 1400mm high. The cigarette frame is moved to the adjustment slide 7 by an AGV or a forklift.

[0029] The electronic control system for the raw tobacco homogenization feeding equipment includes the X-axis, Y-axis, Z-axis, and C-axis, along with a belt servo system and a Z-axis end gripper. The X-axis servo system controls the left and right movement of the transverse guide rail 2; the Y-axis servo system controls the forward and backward movement of the longitudinal guide rail 3; the Z-axis servo system controls the vertical movement of the vertical guide rail 4; and the C-axis servo system controls the rotation mechanism of the gripping manipulator 5. The weighing belt is responsible for final feeding and flow control. The X, Y, and Z axes control the gripping position of the gripping manipulator 5; the C-axis controls the gripping pattern, and the weighing belt performs weighing and flow control. The equipment utilizes a dual-station system with one gripper and one standby for automated and scientific feeding.

[0030] At the tobacco frame docking station, the AGV drops the frame and departs, then adjusts the slide 7 to move the frame toward the conveyor belt 8 to the designated position. Once the frame arrives at the loading station, the electronic control system determines the frame's specifications and controls the corresponding gripper 5 to grab the tobacco leaves. The gripper's gripping mechanism is equipped with a rotating mechanism, and the electronic control system determines whether to select a gripper based on the frame's specifications.

[0031] The grasping manipulator 5 comprises a grasping mechanism and a rotating mechanism, and the grasping mechanism is provided with claws that can be opened or closed.

[0032] Operation mode of the grabbing mechanism: The waiting position of the grabbing mechanism before executing the action is above the tobacco frame. At this time, the grabbing teeth are open and retracted into the grabbing mechanism box; before the grabbing action is executed, the electronic control system first determines whether the grabbing mechanism needs to rotate; after the grabbing mechanism descends to the appropriate height above the tobacco frame, the grabbing teeth extend and close to hook the tobacco leaves; the grabbing mechanism rises to the appropriate height, and the grabbing action is completed.

[0033] Working principle:

[0034] The tobacco frame filled with tobacco leaves is transported by an AGV or a forklift to the adjustment slide 7. The sensor on the adjustment slide 7 senses its position and adjusts the tobacco frame to the set position. The grabbing robot 5 starts working, grabs the tobacco leaves in the tobacco frame, and places the grabbed tobacco leaves on the weighing belt 6 under the displacement adjustment of the horizontal guide rail, longitudinal guide rail, and vertical guide rail. The weighing belt 6 compares the data according to the weight of the tobacco leaves with the system requirements, adjusts its belt conveying speed, and thus controls the weight of the tobacco leaves flowing to the conveyor belt 8, and ultimately achieves refined and homogenized production.

[0035] The above-described embodiments merely represent specific implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of the present application. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the technical concept of the present application, and all such variations and improvements fall within the scope of protection of the present application.
