Description

Technical Field

[0001] The utility model relates to a shelf device, in particular to a device used for loading materials to realize shelf storage. Background Art

[0002] The preparation process of tobacco is relatively complicated. After the tobacco leaves are harvested, they need to be processed in different ways according to their characteristics and processing traditions. The purpose is to remove the green and excess moisture of the tobacco leaves for preservation; during the preparation process, the internal part is initially saccharified and matured to prepare for the complicated processing procedures later. There are several ways to process tobacco leaves: air-drying treatment method, the tobacco processed by this method is the most mellow. The tobacco leaves are first naturally air-dried in an open farm shed, and then placed in large sacks for fermentation; fermentation treatment changes the chemical composition of tobacco, making the flavor softer and reducing its nicotine content; sun-drying treatment method, tobacco leaves are fixed on rings and hung on the walls of the farm shed, using sunlight and natural wind to dry and mature. Almost all oriental tobacco is processed by this method; hot air pipe treatment method, after the tobacco leaves are harvested, they are immediately placed in a closed farm shed, and the hot air convection generated by the hot air pipe heating is used to dry the tobacco leaves. Due to the rapid drying process, the tobacco leaves turn yellow, and this method is often used to process blended tobacco; the open flame baking method, the tobacco processed by this method is the most intense. The tobacco leaves are hung over the open flame, and the rising thick smoke cooks the tobacco leaves and gives the tobacco a unique "smoky" flavor.

[0003] The existing tobacco leaves need to be cured in a tobacco curing room. In order to improve the space utilization, the tobacco curing room generally adopts a multi-layer storage mode for tobacco leaves. In order to adapt to this mode and reduce the labor intensity, a loader needs to be applied to realize automatic loading of tobacco leaves. During the working process of the loader, the transition between different working positions of tobacco leaves requires smoothness, otherwise it will affect the working efficiency of the loader. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a material loading and placing device, which can effectively realize that a clamping rod clamped with materials can smoothly enter the next working position at the placing position.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a material loading and shelving device, including a swing frame, the upper end of the swing frame is hinged on the connecting frame, and a clamping structure is provided at the lower end, the clamping structure is used to clamp a clamping rod, and a power mechanism is movably provided on the connecting frame, the power mechanism is transmission-connected to the swing frame, and under the drive of the power mechanism, the lower end of the swing frame swings between a clamping position and a shelving position. The utility model is characterized in that it also includes a pushing mechanism, the pushing mechanism includes a power structure and a pushing member connected together, and under the action of the power structure, the pushing member is used to push the clamping rod at the shelving position toward the outside.

[0006] The racking device is mainly used on tobacco leaf loaders. At the clamping position, it is used to arrange the tobacco leaves and clamp them onto the clamping rod. After the tobacco leaves are clamped, the swing rack will swing upward to the racking position and release the clamping rod at the racking position so that the clamping rod moves toward the downstream station. Under the action of the power structure, the pusher in the racking device allows the newly released clamping rod to be stably received and transported by the actuator on the downstream side.

[0007] Furthermore, the pushing member is a plate-shaped body, and the pushing member pushes the clamping rod in a manner parallel to the clamping rod. The pushing member is a plate-shaped body, which can well adapt to the structural form of the clamping rod, so that the pushing member can stably push the clamping rod.

[0008] Furthermore, the cross section of the pushing member is L-shaped, which can effectively increase the contact surface between the pushing member and the clamping rod, and can well adapt to the pushing of the clamping rod by the pushing member.

[0009] Furthermore, a support plate extending downward is provided on the pushing member. By providing the support plate, the clamped and hung objects on the clamping rod can be pushed, so that the clamping rod and the clamped and hung objects as a whole can stably move toward the downstream side station.

[0010] Furthermore, the support plate is a strip-shaped body, and there are multiple support plates, which are evenly spaced in the length direction of the pusher. This can effectively reduce the weight on the basis of ensuring the overall pushing effect of the clamping rod and the clamped object, and facilitate the power structure to push the pusher.

[0011] Furthermore, the power structure is fixedly connected to the connecting frame, which well adapts to the movement position of the swing frame, so that the power structure can easily push the clamping rod at the upper rack position.

[0012] Furthermore, the connecting frame is fixedly connected with a vertical plate, the power structure is a power cylinder, the power cylinder is horizontally arranged, the power cylinder is fixedly connected to the vertical plate, the piston rod on the power cylinder passes through the vertical plate, and the pushing member is fixedly connected to the outer end of the piston rod. By providing the vertical plate, the fixing of the power cylinder can be facilitated.

[0013] Furthermore, the vertical plate is provided with a guide sleeve, and the guide rod fixedly connected to the pusher is inserted into the guide sleeve with a gap, and the guide rod is arranged parallel to the piston rod. This makes the movement stability of the pusher good, and is convenient for providing a stable pushing force for the clamping rod.

[0014] Compared with the prior art, the utility model has the beneficial effect that by setting the pushing member, under the drive of the power mechanism, the pushing member is used to push the clamping rod released from the lower end of the swing frame toward the outside, so that the clamping rod can be pushed into place, so that the actuator at the next process can stabilize the clamping rod, thereby effectively ensuring the working stability of the entire loader.

DETAILED DESCRIPTION

[0020] Combined with the drawings in the specification, taking tobacco leaf processing as an example, Figure 1 The tobacco leaf 1 in the figure is drawn in a simple way, but it is actually composed of multiple strips in parallel. The material loading and racking device is used to load tobacco leaves 1 into the tobacco curing room, and the structure includes a material sorting and clamping mechanism, a material transfer mechanism and a material lifting mechanism. A workbench is provided at the material sorting and clamping mechanism, and the tobacco leaves 1 are placed on the workbench and sorted so that the tobacco leaves 1 are arranged in parallel. On the workbench, the tobacco leaves 1 are clamped by a split clamping rod. The material transfer mechanism includes a swing frame 2, the upper end of which is hinged on the connecting frame 3, and a movable clamping structure is provided at the lower end of the swing frame 2, which is clamped at the end position of the clamping rod. A swing cylinder 4 is movably provided on the connecting frame 3, and the piston rod 12 in the swing cylinder 4 is transmission-connected to the swing frame 2. Driven by the swing cylinder 4, the swing frame 2 swings on the connecting frame 3, so that the lower end of the swing frame 2 swings between the clamping position 6 and the racking position 7.

[0021] The material lifting mechanism is arranged on the downstream side of the upper shelf position 7. A chain-type elevator is provided on the material lifting mechanism. The elevator is connected to the horizontal frame 5. The horizontal frame 5 is arranged in the horizontal direction. The horizontal frame 5 is used to place the end of the clamping rod. A driving chain is sleeved on the horizontal frame 5 along its length direction. The driving chain is connected to the motor transmission, and the chain is driven to move under the drive of the motor. The driving chain transports the clamping rod on the horizontal frame 5 to the outside, thereby driving the tobacco leaves 1 of the clamping rod to move to the outside, so that the tobacco leaves 1 can enter the tobacco flue-curing room. The lifting mechanism lifts and lowers the horizontal frame 5 in the vertical direction to meet the loading requirements of the clamping rods on the shelves of different heights in the tobacco flue-curing room.

[0022] In order to facilitate the clamping rod to smoothly enter the cross frame 5 after it escapes from the lower end of the swing frame 2, a pushing mechanism is also provided on the outer side of the upper shelf position 7. The pushing mechanism includes a power structure and a pushing member 13 connected together. The pushing member 13 extends toward the upper shelf position 7. Under the action of the power structure, the pushing member 13 is used to push the clamping rod at the upper shelf position 7 toward the outside, that is, the pushing member 13 pushes the clamping rod toward the cross frame 5. The pushing member 13 is a plate-like body. The pushing member 13 is perpendicular to the forward direction of the clamping rod. The pushing member 13 pushes the clamping rod in a manner parallel to the clamping rod. In order to facilitate the push member 13 to fit with the clamping rod, the cross section of the pushing member 13 is L-shaped. When the pushing member 13 pushes the clamping rod, the pushing member 13 fits with the bottom and side surfaces of the clamping rod.

[0023] After the tobacco leaf 1 is hung on the clamp rod, the drooping part of the tobacco leaf 1 is relatively long. In order to improve the overall stability when pushing, a support plate 14 extending downward is provided on the pushing member 13. When the pushing member 13 pushes the clamp rod, the support plate 14 will contact the drooping part of the tobacco leaf 1. As shown in the figure, the support plate 14 is a strip-shaped body, and there are multiple support plates 14, which are evenly spaced in the length direction of the pushing member 13.

[0024] The connecting frame 3 is fixedly connected with a vertical plate 9, which is arranged vertically. The power structure is a power cylinder 8, which is arranged horizontally. The power cylinder 8 is fixedly connected to the vertical plate 9. The piston rod 12 on the power cylinder 8 passes through the vertical plate 9 with a gap. The pushing member is fixedly connected to the outer end of the piston rod 12. The vertical plate 9 is provided with a guide sleeve 11. The guide rod 10 fixedly connected to the pushing member is inserted into the guide sleeve 11 with a gap. The guide rod 10 is arranged parallel to the piston rod 12. There are two guide rods 10, and the two guide rods 10 are arranged on opposite sides of the piston rod 12.
