DETAILED DESCRIPTION

[0032] like Figures 1 to 15 As shown, the present invention mainly includes a first conveyor 1, an acquisition unit, a transition mechanism, a second conveyor 7, a positioning mechanism and a canning mechanism. The present invention is described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1 As shown, the first conveyor includes a pair of first rollers 11 and a first belt 12 disposed between the two first rollers. A obtaining unit is disposed at the front end of the first conveyor, through which the packaging barrels are picked up one by one and placed on the first conveyor.

[0034] like Figures 2 to 9 As shown, the acquisition unit includes a storage mechanism, a blocking mechanism and a flipping mechanism. The storage mechanism is used to store and place the packaging barrels, the blocking mechanism is used to block and limit the packaging barrels, and the flipping mechanism is used to flip the picked packaging barrels 90 degrees and place them on the first conveyor. Figure 3 As shown, the storage mechanism includes an L-shaped storage rack 2, a spring assembly 21 arranged on the vertical part of the storage rack, a top plate 22 arranged on the spring assembly, and a support block 23 arranged on the horizontal part of the storage rack. The spring assembly includes a bellows and a push spring arranged in the bellows. The first end of the push spring is fixedly connected to the vertical part of the storage rack, and the second end of the push spring is fixedly connected to the top plate. The support block is a long strip structure, and a groove is arranged in the upper surface of the support block. The packaging barrel 3 nested inside and outside is placed on the support block and contacts the inner wall of the groove. Figure 4 As shown, the packaging barrel is a conical structure, and the packaging barrels are stacked together when placed. The bottom of the packaging barrel contacts the top plate, and when the spring assembly is compressed, the setting of the spring assembly has the effect of pushing the packaging barrel to the side away from the spring assembly. The setting of the blocking mechanism can limit the packaging barrel to prevent the packaging barrel from falling off the storage rack under the action of the spring assembly. When placed, the packaging barrel is placed flat on the support block.

[0035] like Figure 5 , Figure 6 As shown, the blocking mechanism includes a fixed plate 51, two pairs of track plates 52 arranged on the fixed plate, a first slide 53 slidably arranged between one pair of track plates, a second slide 54 slidably arranged between the other pair of track plates, a swing motor 59 fixed on the top of the fixed plate, a tilting rod 57 fixed on the output end of the swing motor, a first connecting rod 56 arranged between the first end of the tilting rod and the ear plate 55 on the top of the first slide, a second connecting rod 57 arranged between the second end of the tilting rod and the ear plate 55 on the top of the second slide, a guide rod 62 slidably arranged in the first slide and the second slide, a wheel frame 6 fixed at the bottom of the guide rod, a blocking wheel 61 rotatably mounted on the wheel frame, a blocking spring 63 arranged between the wheel frame and the first slide and between the wheel frame and the second slide, a damping member is arranged between the blocking wheel and the wheel frame, and under the action of the damping member, the blocking wheel cannot rotate relative to the wheel frame. The blocking wheel is a rubber member, and the swing motor drives the tilting rod to swing, so that the first and second slides are at different heights. The first and second connecting rods are hingedly connected to the tilting rod, and the first and second connecting rods are also hingedly connected to the ear plate. The two blocking wheels are alternately at the lowest point, and the blocking wheel at the lowest point blocks the packaging barrel, and cooperates with the push spring to clamp the packaging barrel. After the blocking wheel on the second slide contacts the end of the packaging barrel, the packaging barrel is in a waiting state. When the electromagnet extends into the packaging barrel and adsorbs the packaging barrel, the swing motor moves the first slide down and the second slide up. At this time, the blocking wheel on the first slide contacts the supply packaging barrel on the left side of the packaging barrel to be taken, and then the packaging barrel is re-clamped through the cooperation of the blocking wheel on the first slide and the push spring. At this time, the packaging barrel to be taken is already in an unrestricted state, such as Figure 8 As shown, the packaging bucket can be removed and placed on the first conveyor by the turnover mechanism. A gap for avoiding the packaging bucket is provided on the horizontal part of the turnover frame so that the packaging bucket rotates 90 degrees with the turnover rod.

[0036] When the first or second slide is at the lowest point, the blocking wheel keeps in contact with the packaging barrel under the action of the blocking spring, thereby achieving the positioning of the packaging barrel. However, when the first or second slide moves upward, the compressed blocking spring begins to extend, and the blocking wheel still contacts the packaging barrel, and still has a blocking effect on the packaging barrel for a certain period of time. Therefore, it can avoid the situation where the packaging barrel is pushed out by the spring due to the immediate separation of the blocking wheel and the packaging barrel.

[0037] like Figure 2As shown, the flipping mechanism includes a T-shaped flipping frame 4 arranged above the first conveyor, a rack 43 slidably arranged on the horizontal part of the flipping frame, a translation gear 42 meshing with the rack, a translation motor 41 driving the translation gear to rotate, a flipping motor 44 fixed on the rack, a flipping rod 45 fixed at the output end of the flipping motor, and an electromagnet 46 fixed at the end of the flipping rod. Under the action of the translation motor, the rack, the flipping motor and the flipping rod are driven to move left and right in the horizontal plane, and under the action of the flipping motor, the flipping rod is driven to swing in the vertical plane. Figure 8 As shown in FIG. 1 , the electromagnet and the flip rod are driven by the translation motor to extend into the packaging barrel and absorb the packaging barrel. With the reverse action of the translation motor, the packaging barrel moves to the side away from the storage rack with the flip rod. When the flip motor moves to the top of the first conveyor, as shown in FIG. Fig. 9 As shown, the flip motor is activated to rotate the flip rod 90 degrees counterclockwise, after which the electromagnet is powered off, and the packaging barrel adsorbed on the electromagnet is separated from the electromagnet until it falls on the first belt of the first conveyor. After the packaging barrel falls on the first belt, the electromagnet is removed from the packaging barrel. After that, the flip rod is reset, and the packaging barrel is conveyed backward with the movement of the first belt. The packaging barrel is made of stainless steel so that the electromagnet can be adsorbed and it can also prevent rust.

[0038] In this way, the packaging barrels are added and placed on the first conveyor one by one through the acquisition unit, and the packaging barrels are transported and moved to the subsequent process along the first conveyor. A second conveyor 7 is provided at the rear side of the first conveyor, and the second conveyor includes a pair of second rollers 71 and a second belt 72 arranged between the second rollers. A transition mechanism is provided between the first conveyor and the second conveyor.

[0039] like Fig.10 , Fig.11 As shown, the transition mechanism includes a plurality of transition shafts 8 arranged in parallel and coplanar, a first gear 81 arranged coaxially with the transition shaft, and a second gear 82 arranged between each two adjacent first gears. The first and second gears are externally meshed, so that the plurality of transition shafts can act synchronously. In the process of transferring the packaging barrel from the first conveyor to the second conveyor, the transition mechanism plays a role of smooth transition, so that the packaging barrel is smoothly transferred from the first conveyor to the second conveyor.

[0040] A filling mechanism is provided above the front end of the second conveyor, such as Fig.14 , Fig.15As shown, the canning mechanism includes a canning tube 9, a lifting tube 93, a clamp 91 fixed on the outer wall of the canning tube, and a lifting cylinder 92 arranged between the clamp and the lifting tube. The upper end of the lifting tube is sleeved on the lower end of the canning tube. When the packaging barrel moves below the canning tube, the lifting cylinder drives the lifting tube to move downward, so that the lower end of the lifting tube extends into the packaging barrel. At this time, the processed coal sample can pass through the canning tube and the lifting tube into the packaging barrel. A valve is arranged on the canning tube to facilitate the opening of the canning tube.

[0041] The second conveyor is always in operation. To ensure that the packaging barrels stay below the canning tube, a pair of left and right positioning mechanisms are provided above the second conveyor. Fig.12 , Fig.13 As shown, the positioning mechanism includes a positioning cylinder 75, a connecting rod 73 fixed on the piston rod of the positioning cylinder, and a pair of positioning rods 74 fixed on the connecting rod. When the piston rod of the positioning cylinder is extended, the positioning rods can be driven to extend forward. Figure 1 As shown, when the packaging barrel contacts the positioning rod of the right positioning mechanism, the packaging barrel is located directly below the canning tube. At this time, the lifting cylinder drives the lower end of the lifting tube to extend into the packaging barrel, and then the coal sample can be canned. After the canning is completed, the lifting tube is reset under the action of the lifting cylinder. Then the positioning rod of the right positioning mechanism moves backward, and the packaging barrel is conveyed backward with the second conveyor without obstruction. After the packaging barrel passes the right positioning mechanism, the right positioning mechanism is reset. The left positioning mechanism is actuated, so that the positioning rod of the left positioning mechanism moves backward. At this time, the blocking effect of the left positioning mechanism on the packaging barrel on the first conveyor disappears. The packaging barrel on the first conveyor passes the left positioning mechanism and moves to the second conveyor until it contacts the positioning rod of the right positioning mechanism. Then the left positioning mechanism is reset, and it plays a blocking role on the packaging barrel on the first conveyor again.

[0042] The present invention can sequentially realize the acquisition of packaging barrels, the placement of packaging barrels, and the canning of coal samples. The whole process is connected sequentially, and no human intervention is required, which frees up manpower and improves efficiency. The lifting pipe extends into the packaging barrel to implement canning, which reduces the flying degree of coal powder in the coal sample during filling. The stacked packaging barrels can be placed on the storage rack by people, and the packaging barrels are placed on the storage rack in a flat manner, and can realize self-movement and replenishment, which is convenient for the flip mechanism to take.
