Material transfer system

Abstract

The utility model discloses a material transfer system which comprises a positioning assembly, a valve opening mechanism and a movable stock bin. The valve opening mechanism is arranged on the mounting seat in a sliding manner and comprises a rotating shaft and a limiting block arranged on the rotating shaft; a bottom valve is arranged at the bottom of the movable stock bin and comprises a valve body and an opening and closing piece for controlling opening and closing of the valve body, and the opening and closing piece can be in butt joint with the limiting block. When the movable stock bin is transferred to the positioning assembly, the opening and closing piece of the bottom valve is in butt joint with the limiting block of the valve opening mechanism, due to the fact that the valve opening mechanism is arranged on the installation base in a sliding mode, when positioning deviation exists between the opening and closing piece and the valve opening mechanism, the valve opening mechanism can slide after being extruded by the opening and closing piece, and therefore automatic correction is achieved. Abrasion can be reduced, and the problem that the bottom valve is not tightly closed due to excessive abrasion is avoided; after butt joint is completed, the rotating shaft drives the limiting block to rotate, the opening and closing piece synchronously rotates along with the limiting block, and automatic valve opening is achieved.

[0002] In industries such as food, pharmaceuticals, health products, milk powder, and new energy, mobile silos are widely used for temporary storage and transfer transportation of materials. With the advent of the Industrial 4.0 era, automation and unmanned operation have been widely promoted, and AGV transfer - automatic docking - automatic valve opening - automatic blanking, etc. have become the development trend of material transfer technology. Since mobile silos usually do not have a valve opening mechanism, after the mobile silo is docked, the bottom valve of the silo needs to be docked with the driving device, and the bottom valve is opened through the driving device. For example, in the technical solution disclosed in CN217836877U, after the discharge port and the receiving port of the mobile silo are docked, it is necessary to drive the driving device along the guide rail to dock with the butterfly valve through the cylinder, and then open the butterfly valve. However, in the process of opening the valve, because the docking of the driving device and the butterfly valve requires a long waiting time, the blanking operation time is long and the operation efficiency is low.

[0003] At the same time, affected by the processing precision of the positioning mechanism and the mobile silo, etc., the valve opening driving device will cause the misalignment of the valve opening mechanism and the bottom valve, resulting in serious wear of the valve opening mechanism and the bottom valve of the mobile silo not closing tightly.

[0032] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0033] Figures 1 to 6 An embodiment of the material transfer system of the present utility model is shown. The material transfer system of this embodiment includes a positioning component 1, a valve opening mechanism 3, and a moving bin 5; the valve opening mechanism 3 is slidably arranged on the mounting base 2, and the valve opening mechanism 3 includes a rotating shaft 34 and a limiting block 31 arranged on the rotating shaft 34; a bottom valve 4 is provided at the bottom of the moving bin 5, and the bottom valve 4 includes a valve body and an opening and closing member 41 for controlling the opening and closing of the valve body, and the opening and closing member 41 can be docked with the limiting block 31. Specifically, refer to Figure 6 In this embodiment, the bottom valve 4 is a butterfly valve. A valve plate is provided inside the valve body, and the valve plate is controlled to open and close by a valve rod. The opening and closing member 41 is preferably a block-shaped member and is installed at one end of the valve rod. The opening and closing of the bottom valve 4 is realized by driving the valve rod to rotate forward and backward by the opening and closing member 41. Of course, in other embodiments, the bottom valve 4 can also adopt other types of valves.

[0034] When the material transfer system of this embodiment is in use, when the moving bin 5 is transferred to the positioning component 1, the opening and closing member 41 of the bottom valve 4 is docked with the limiting block 31 of the valve opening mechanism 3. Since the valve opening mechanism 3 is slidably arranged on the mounting base 2, when there is a positioning deviation between the opening and closing member 41 and the valve opening mechanism 3, the valve opening mechanism 3 can slide after being squeezed by the opening and closing member 41, thereby realizing automatic correction, which is beneficial to reducing wear and avoiding the problem that the bottom valve 4 cannot be tightly closed due to excessive wear; after the docking is completed, the rotating shaft 34 drives the limiting block 31 to rotate, and the opening and closing member 41 rotates synchronously with the limiting block 31 to realize automatic valve opening, with a simple structure and a high degree of automation.

[0035] Further, in this embodiment, a limiting groove 311 for docking with the opening and closing member 41 is provided on the limiting block 31. The width of the upper part of the limiting groove 311 is greater than that of the lower part. The structure with a wider upper part and a narrower lower part facilitates the smooth insertion of the opening and closing member 41 into the limiting groove 311 from top to bottom, and can reduce the design gap between the opening and closing member 41 and the side wall of the limiting groove 311;

[0036] Meanwhile, the width of the upper part of the area of the opening and closing member 41 for docking with the limiting groove 311 is greater than that of the lower part. Specifically, refer to Figure 6 , the opening and closing member 41 is a wedge block, which facilitates the smooth insertion into the limiting groove 311, and can reduce the design gap between the opening and closing member 41 and the side wall 311a of the limiting groove 311.

[0037] Further, in this embodiment, the limiting groove 311 includes a bottom wall 311b close to the rotating shaft 34 side, and there is a gap between the end of the opening and closing member 41 and the bottom wall 311b; the limiting groove 311 further includes a side wall 311a for circumferentially limiting the opening and closing member 41, and at least one surface of the side wall 311a does not contact the opening and closing member 41. For example, the two side walls 311a of the limiting groove 311 are parallel to each other, and the width is greater than the width of the corresponding part of the opening and closing member 41. After docking, at least one side wall 311a does not contact the opening and closing member 41. Refer to Figure 3 , there are gaps between the two side walls 311a and the bottom wall 311b of the limiting groove 311 and the opening and closing member 41, which can improve the docking accuracy of the opening and closing member 41 and the limiting groove 311 in the vertical direction and along the driving shaft direction, further reduce the difficulty of the opening and closing member 41 being inserted into the limiting groove 311 and the friction caused by hard contact between the two, and avoid the adverse effects on each component due to docking.

[0038] Specifically, refer to Figures 3 to 5 , in this embodiment, the valve opening mechanism 3 further includes a mounting plate 33 and a rotary driving member 32 (such as a motor, etc.) provided on the mounting plate 33. The rotary driving member 32 is connected to one end of the rotating shaft 34, the other end of the rotating shaft 34 is connected to the limiting block 31, and the bottom of the mounting plate 33 is slidably connected to the mounting seat 2. When the limiting block 31 is subjected to the extrusion of the opening and closing member 41, it can drive the rotating shaft 34, the rotary driving member 32 and the mounting plate 33 as a whole to slide horizontally relative to the mounting seat ( Figure 5 the sliding direction in

[0039] Specifically, refer to Figure 3 , in this embodiment, a bushing 35 is provided on the mounting plate 33, and the rotating shaft 34 passes through the bushing 35. The bushing 35 can provide sealing and protection for the rotating shaft 35. Further, a bush 36 is provided between the bushing 35 and the rotating shaft 34. Of course, in other embodiments, a rolling bearing can also be used instead of the bush 36. The bush 36 can prevent the bushing 35 from interfering with the rotational movement of the rotating shaft 34, and at the same time, the top block 37 can be installed on the bushing 35.

[0040] Further, in this embodiment, a guiding block 21 is provided on the mounting base 2. A horizontally arranged sliding groove 211 is provided on the guiding block 21, and the bottom of the mounting plate 33 is arranged in the sliding groove 211. The sliding groove 211 provides a guiding function for the horizontal sliding of the mounting plate 33, avoiding deviation during the sliding process of the mounting plate 33, and at the same time reducing the sliding resistance to make the sliding process smoother.

[0041] Further, in this embodiment, sealing plates 22 are provided at both ends of the guiding block 21, and an elastic resetting member 23 is provided between the sealing plates 22 and the mounting plate 33. On the one hand, the elastic resetting member 23 can provide a certain damping for the mounting plate 33. On the other hand, after the opening and closing member 41 rises and separates from the limiting block 31, it can drive the mounting plate 33 and the limiting block 31 and the like to reset integrally to prepare for the next valve opening.

[0042] Further, in this embodiment, a positioning convex portion 221 is provided on the sealing plate 22, a positioning groove 331 is provided on the mounting plate 33, the elastic resetting member 23 is a spiral spring, one end of the elastic resetting member 23 is sleeved on the positioning convex portion 221, and the other end of the elastic resetting member 23 is arranged in the positioning groove 331, thereby realizing the reliable installation of the spiral spring.

[0043] Specifically refer to Figure 6 , in this embodiment, a groove is provided on the opening and closing member 41, and a locking block 42 is hinged on the valve body, so that the locking block 42 can swing up and down. The lower part of the locking block 42 is positioned in the groove. At this time, the opening and closing member 41 is locked and cannot rotate, which can prevent the bottom valve 4 from being accidentally opened; a top block 37 capable of ejecting the locking block 42 from the groove is provided above the limiting block 31. Specifically refer to Figure 3 , when the moving bin 5 falls onto the positioning assembly 1, the locking block 42 contacts the top block 37 and thus rotates upward. After the lower part of the locking block 42 separates from the groove, the limiting block 31 can drive the opening and closing member 41 to rotate synchronously to open the valve. After the opening and closing member 41 rises and separates from the limiting block 31, the locking block 42 can rotate downward and reset under the action of its own gravity and / or torsion spring and other components, and lock the bottom valve 4 again, further improving the reliability of the system.

Positioning plates 12 are provided on the end faces and the outer sides of both ends of the load-bearing beam 11. An inclined guiding portion 121 is provided on the upper portion of the positioning plate 12. The mounting seat 2 and the valve opening mechanism 3 are both located between the two load-bearing beams 11. The inclined guiding portion 121 can guide the legs of the moving bin 5 to smoothly drop onto the two load-bearing beams 11. The positioning plates 12 on the end faces and the outer sides of both ends of the load-bearing beam 11 can achieve accurate positioning of the moving bin 5 in the front, rear, left, and right directions, and also help to a certain extent the docking of the opening and closing member 41 and the limiting block 31.
