Description

Technical Field

[0001] The invention relates to flue-cured tobacco baking auxiliary equipment, and in particular to a tobacco loading and unloading device for a flue-cured tobacco room with good continuity and high efficiency in loading and unloading tobacco. Background Art

[0002] Loading and unloading tobacco in the flue-curing room is a crucial step in tobacco curing. Loading involves hanging tobacco rods or tobacco clips (collectively, these tools) from the tobacco racks in the flue-curing room. Unloading involves removing the tobacco clips from the racks after the leaves have dried and regained moisture. Tobacco racks in flue-curing rooms come in three-tier or four-tier styles. The second and third beams of three-tier racks are taller, while the third and fourth beams of four-tier racks are taller. Loading and unloading tobacco requires tools. There are two existing tobacco loading and unloading tools. One is directly fixed in the tobacco flue-curing room, with good tobacco loading continuity, but the environment in the tobacco flue-curing room is humid and hot, and the service life is short. In addition, it is large in size and cannot be flexibly used in other tobacco flue-curing rooms. The cost of supporting tobacco flue-curing room renovation and machine investment is high; the other is movable and can be flexibly used in various tobacco flue-curing rooms with low cost, but the tobacco loading and unloading continuity is poor and the loading and unloading efficiency is low. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a tobacco loading and unloading device for a tobacco flue-curing room with good continuity and high efficiency. The device has good continuity and high efficiency, can be flexibly used in various tobacco flue-curing rooms, has low cost and low modification cost.

[0004] The purpose of the present invention is achieved through the following technical solutions: The present invention relates to a tobacco loading and unloading device for a tobacco flue-curing room with good continuity and high efficiency in loading and unloading tobacco, comprising a lifting frame, wherein the lifting frame comprises two stepped lifting rods arranged in a mirror image, and the lifting horizontal rods opposite to each other of the two lifting rods respectively lift the two ends of a tobacco leaf clamping tool with tobacco leaves clamped therein, and a transport frame is movably provided in the lifting frame, wherein the transport frame comprises two stepped transport rods arranged in a mirror image, and the transport horizontal rods and vertical rods of the two transport rods are opposite to the lifting horizontal rods and vertical rods of the two lifting rods one by one, and the relative positions of the two transport rods are the same. The pair of transporting horizontal rods can respectively lift the two ends of the tobacco leaf clamping tool with tobacco leaves clamped therein, and it also includes a driving mechanism, which drives the transport frame to move along a rectangular motion trajectory. Every time the transport frame moves along the rectangular motion trajectory, each transporting horizontal rod transports the tobacco leaf clamping tool with tobacco leaves clamped therein on each lifting horizontal rod to the adjacent next lifting horizontal rod and / or tobacco beam, or transports the tobacco leaf clamping tool with tobacco leaves clamped therein on each lifting horizontal rod and / or tobacco beam to the adjacent next lifting horizontal rod.

[0005] Furthermore, the driving mechanism includes a linear motion mechanism and a lifting motion mechanism. The linear motion mechanism is parallel to the horizontal lifting rod. One end of the linear motion mechanism is connected to the lifting frame and the other end is connected to the lifting motion mechanism. The lifting motion mechanism is parallel to the vertical rod of the lifting rod. The end of the lifting motion mechanism is connected to the transport frame.

[0006] Furthermore, the linear motion mechanism and the lifting motion mechanism are connected to a controller.

[0007] Furthermore, a sliding structure is connected between the linear motion mechanism and the lifting motion mechanism, and the sliding structure is slidably arranged on the lifting frame.

[0008] Furthermore, it also includes a base, and a lifting device is connected between the base and the bottom of the lifting frame.

[0010] Furthermore, the lower ends of the two lifting rods are detachably connected to extended lifting rods, which are stepped. The lower ends of the two carrying rods are detachably connected to extended carrying rods, which are stepped. The carrying horizontal rods and vertical rods of the extended carrying rods are opposite to the carrying horizontal rods and vertical rods of the extended lifting rods.

[0011] Furthermore, a first detector is provided at the high end of the transport rack for detecting tobacco leaves on the tobacco beam near the position, and the first detector is connected to a controller.

[0012] Furthermore, a second detector is provided at the lower end of the transport rack for detecting the tobacco leaf clamping tool on the lowest lifting horizontal rod, and the second detector is connected to the controller.

[0013] Furthermore, a track is provided on the tobacco beam, and rollers capable of rolling on the track are provided at both ends of the tobacco leaf clamping tool.

[0014] The beneficial effects of the present invention are: The tobacco loading and unloading device for a flue-curing room proposed by the present invention has good continuity and high efficiency in tobacco loading and unloading. A driving mechanism drives the transport frame to move along a rectangular motion trajectory. Each time the transport frame moves along the rectangular motion trajectory, each transport horizontal rod transports the tobacco leaf clamping tools with tobacco leaves on each lifting horizontal rod to the next adjacent lifting horizontal rod and / or tobacco beam, or transports the tobacco leaf clamping tools with tobacco leaves on each lifting horizontal rod and / or tobacco beam to the next adjacent lifting horizontal rod, thereby realizing the loading and unloading of tobacco to the high-rise tobacco beams in the flue-curing room, and having good continuity and high efficiency in tobacco loading and unloading, and can be flexibly used in various tobacco flue-curing rooms.

At this time, the lifting device rises to a certain height and is suitable for a person standing on the ground to place the tobacco leaf clamping tool containing tobacco leaves onto the lifting horizontal rod at the lower end of the extended lifting rod.

[0019] When loading tobacco, the controller of the cigarette loading and unloading device stops the driving mechanism when the first detector detects tobacco leaves for more than a certain time. When unloading tobacco, the controller stops the driving mechanism when the second detector detects tobacco leaf clamping tools for more than a certain time, thereby preventing the tobacco leaf clamping tools from clumping together.

[0033] Example 2 like Figure 4As shown, the difference from Example 1 is that the lower ends of the two lifting rods 2 are detachably connected to an extended lifting rod 13. Various methods of detachable connection are possible, such as a vertical first connecting rod connected to the lower side of the end of the upper horizontal lifting rod of the extended lifting rod 13. The first connecting rod and the vertical rod of the lifting rod 2 are provided with corresponding through holes, and the first connecting rod and the vertical rod of the lifting rod 2 are connected by bolts passing through the corresponding through holes. The extended lifting rod 13 is stepped, that is, the extended lifting rod 13 is composed of multiple horizontal lifting rods and vertical rods connected in an interlaced manner, and the two extended lifting rods 13 are mirror images. The lower ends of the two carrying rods 4 are detachably connected to an extended carrying rod 14. Various methods of detachable connection are possible, such as a vertical second connecting rod connected to the lower side of the end of the upper horizontal carrying rod of the extended carrying rod 14. The second connecting rod and the vertical rod of the carrying rod 4 are provided with corresponding through holes, and the second connecting rod and the vertical rod of the carrying rod 4 are connected by bolts passing through the corresponding through holes. The extended transport rod 14 is stepped, that is, the extended transport rod 14 is formed by a plurality of transport horizontal rods and vertical rods connected in an interlaced manner, and the transport horizontal rods and vertical rods of the extended transport rod 14 are opposite to the lifting horizontal rods and vertical rods of the extended lifting rod 13 one by one.

[0034] When this embodiment is used in a four-layer hanging tobacco rack flue-curing room, when loading tobacco into the third layer tobacco beam 16 or unloading tobacco from the third layer tobacco beam 16, refer to Example 1. When loading tobacco into the fourth layer tobacco beam 16 or unloading tobacco from the fourth layer tobacco beam 16, it is necessary to connect the extended lifting rod 13 to the two lifting rods 2, and connect the extended carrying rod 14 to the two carrying rods 4. The height of the lifting frame 1 is adjusted by the lifting device 11 so that its high end is close to the fourth layer tobacco beam 16 from the lower side of the fourth layer tobacco beam 16. At this time, it is suitable for a person standing on the ground to place the tobacco leaf clamping tool 19 with tobacco leaves on the lower end lifting horizontal rod or to take the tobacco leaf clamping tool 19 with tobacco leaves from the lower end lifting horizontal rod.

[0035] Example 3 The difference from Example 1 is that: A first detector 15 is provided on the front side of the high end of the transport rack 3, which can detect tobacco leaves on the tobacco beam 16 near the position. A second detector is provided on the top of the low end transport horizontal rod of the transport rack 3, which can detect the tobacco leaf clamping tool 19 on the lowest lifting horizontal rod. The first detector 15 and the second detector are distance detectors.

[0036] When loading tobacco, the controller stops the driving mechanism when the first detector 15 detects tobacco leaves for more than a certain time. When unloading tobacco, the controller stops the driving mechanism when the second detector detects tobacco leaf clamping tools 19 for more than a certain time, to prevent the tobacco leaf clamping tools 19 from clumping.

When the tobacco leaf clamping tool 19 is lifted by a lifting rod, the tobacco leaf clamping tool 19 can move along the track 17. Baffles 20 are installed 5 cm at both ends of the tobacco leaf clamping tool 19 to prevent damage to the tobacco leaves due to friction when the tobacco leaf clamping tool 19 moves along the track 17. Each horizontal carrying rod and each horizontal lifting rod has a groove, and the end of the tobacco leaf clamping tool 19 is located in the groove to prevent it from falling.
