[0029] The storage mechanism 1 is used for storing goods. The goods are slid from the storage mechanism 1 to the buffer mechanism 2 for buffering, and then slid into the conveying mechanism 3 for conveying. In the process of blanking, automatic blanking of goods is realized. Without the need for additional tools, the goods can be taken off from the storage mechanism 1, which is convenient and fast to use, and has higher practicality. The storage mechanism 1 and the buffer mechanism 2 are both provided with a blocking structure 4 for blocking the goods. By blocking the goods through the blocking structure 4, the interval time of blanking of each goods can also be made the same.

[0030] In the embodiment, as Figures 1-4 shown, the storage mechanism 1 includes a storage rack 101. A plurality of support frames 102 are fixedly arranged on the storage rack 101 in an inclined manner. A plurality of placing rollers 103 are arranged on each support frame 102.

[0031] The support frames 102 are in a multi-row structure, and each row of support frames 102 is in a multi-layer structure, which can be used to place more goods. The front end of each support frame 102 is provided with a blocking structure 4. The goods are placed on the supporting plate 104, and the blocking structure 4 can limit the supporting plate 104 through the rectangular hole 105, so as to block the goods. The goods can be stacked on the support frame 102. When the goods need to be unloaded, the blocking structure 4 no longer blocks the goods, and the goods can be conveyed to the buffer mechanism 2 and then sent out through the conveying mechanism 3.

[0032] In the embodiment, as shown in Figures 5-8 The buffer mechanism 2 includes a fixed frame 201, and the fixed frame 201 is provided with a moving frame 202. The fixed frame 201 is provided with a moving structure 203 for driving the moving frame 202 to move forward and backward. The moving frame 202 is provided with a buffer structure 205 for receiving goods and a lifting structure 204 for driving the buffer structure 205 to move up and down.

[0033] The lifting structure 204 drives the buffer structure 205 to move up and down, so that the buffer structure 205 is connected with the multi-layer support frame 102. At the same time, the moving structure 203 can make the buffer structure 205 connected with the support frame 102 arranged in front and back.

[0034] As a specific structure of the moving structure 203, as shown in Figure 5 The moving structure 203 includes two moving shafts 2031 rotatably arranged on the moving frame 202 through bearings.

The two transmission wheels are drivingly connected with a transmission belt. The output shaft of the rotating motor and the moving shaft 2031 adopt a belt transmission mode, so that the moving shaft 2031 can rotate, thereby making the moving wheel 2032 move in the fixed frame 201, and driving the moving frame 202 to move forward and backward in the fixed frame 201.

[0036] As a specific structure of the lifting structure 204, as shown in Figures 5-6As shown, the lifting structure 204 comprises two transmission shafts 2041 rotatably arranged on the moving frame 202 through bearings, the front and rear ends of the two transmission shafts 2041 are fixed with transmission sprockets 2042, the outer surfaces of the rear two transmission sprockets 2042 and the outer surfaces of the front two transmission sprockets 2042 are drivingly connected with a transmission chain 2043, the top surface of the moving frame 202 is fixed with a driving motor 2044, the output end of the driving motor 2044 and the outer surface of the top transmission shaft 2041 are fixed with driving sprockets 2045, and the outer surfaces of the two driving sprockets 2045 are drivingly connected with a driving chain 2046.

[0037] Due to the transmission effect of the two driving sprockets 2045 and the driving chain 2046, when the output end of the driving motor 2044 rotates, the top transmission shaft 2041 can rotate, and due to the transmission effect of the two transmission sprockets 2042 and the transmission chain 2043, the side surfaces of the two transmission chains 2043 can drive the buffer structure 205 to move up and down, and drive the buffer structure 205 to butt against the support frame 102 arranged above and below the storage mechanism 1.

[0038] As a specific structure of the buffer structure 205, as shown in Figure 5 , Figures 7-8 the buffer structure 205 comprises a buffer frame 2051, the right end of the buffer frame 2051 is hingedly connected with a buffer turnover frame 2052, the top surface of the buffer turnover frame 2052 is rotatably provided with a plurality of buffer rollers 2053, the buffer frame 2051 is fixed with a buffer driving cylinder 2054, and the output end of the buffer driving cylinder 2054 is hingedly connected with a buffer connecting plate 2055 fixed on the buffer turnover frame 2052.

[0039] The output end of the buffer driving cylinder 2054 lifts the buffer turnover frame 2052 through the buffer connecting plate 2055, so as to conveniently adjust the turnover angle of the buffer turnover frame 2052.

[0040] In addition, as shown in Figures 2-3 , Figure 8 the blocking structure 4 comprises a limiting frame 401, a rotating rod 402, two limiting sleeves 403 and two blocking rods 404, the rotating rod 402 is rotatably arranged in the limiting frame 401, the rotating rod 402 can be automatically reset, the two blocking rods 404 are movably connected with the two ends of the rotating rod 402 respectively, and the two limiting sleeves 403 are sleeved on the outer surfaces of the two blocking rods 404 respectively.

[0041] As for how the rotating rod 402 is automatically reset, the inner wall of the limiting frame 401 is rotatably provided with a connecting shaft through a bearing, the rotating rod 402 is fixed on the outer surface of the connecting shaft, a torsional spring is sleeved on the outer side of the connecting shaft, one end of the torsional spring is inserted into the rotating rod 402 and fixed therewith, the other end of the torsional spring is inserted into the limiting frame 401 and fixed therewith, and in the initial state, the right end of the rotating rod 402 is higher than the left end in height under the action of the torsional spring.

The end of the rotating rod 402 is freely movable in the rectangular movable hole at the end of the blocking rod 404, and the blocking rod 404 only moves up and down in the limiting sleeve 403.

[0043] The blocking structure 4 arranged on the storage mechanism 1 is shown in FIG. 4. Figure 2 As shown in the figure, the limiting sleeve 403 and the limiting frame 401 are fixed on the support frame 102. In the initial state, the right end of the rotating rod 402 is higher than the left end under the action of the torsional spring, and the goods are blocked by the right end blocking rod 404. As to how to drive the right end blocking rod 404 to reset, the unloading blocking driving element 5 is arranged on the buffer frame 2051. The unloading blocking driving element 5 includes an unloading blocking cylinder 501, and the output end of the unloading blocking cylinder 501 is fixed with a driving wheel 502.

Then, the driving wheel 502 is removed from the left end of the rotating rod 402, the rotating rod 402 resets to the initial state due to the action force of the torsional spring, the left end blocking rod 404 no longer blocks the goods, and the goods can slide into the buffer turnover frame 2052.

As to how to drive the right end blocking rod 404 to reset, the buffer blocking cylinder 6 is fixed on the buffer frame 2051.

[0046] The output end of the buffer blocking cylinder 6 can push the left end of the rotating rod 402 to move upward, so as to drive the left end blocking rod 404 to move upward in the left end limiting sleeve 403, and the right end blocking rod 404 to move downward in the right end limiting sleeve 403. Through the upward and downward movement of the left and right blocking rods 404, the buffer and transfer of the goods can be realized.
