DETAILED DESCRIPTION

[0021] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present utility model are given for the convenience of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0022] As Figures 1-4 shown, the technical solution of the present utility model provides a goods picking mechanism, including a support frame 3, a goods picking shelf 4 slidably connected to the support frame 3, and a driving air cylinder 5 for driving the goods picking shelf 4 to move up and down. The support frame 3 and the driving air cylinder 5 are both located on one side of the conveyor line 1, and the goods picking shelf 4 is located below the conveyor line 1. The driving air cylinder 5 is inverted, the driving air cylinder 5 is installed on the support frame 3, and the output end of the air cylinder is connected to the goods picking shelf 4. The goods picking shelf 4 is driven by the driving air cylinder 5 to move up and down through the gap between adjacent conveyor rollers 2.

[0023] This solution externalizes the driving air cylinder 5 and the support frame 3, and sets the goods picking shelf 4 below the conveyor line 1, solving the problem of compact space for the linkage of the AGV and the stacker to pick up goods; the inverted driving air cylinder 3 compresses the height space, is suitable for use scenarios with limited height, and saves material costs.

[0024] When picking up goods, the AGV places the goods on the conveyor line 1, and then conveys the goods to the picking location. The gap between adjacent conveyor rollers 2 at the picking location is relatively large. The driving air cylinder 5 drives the goods picking shelf 4 to move upward through the gap between adjacent conveyor rollers 2, and then lifts the goods. Then the stacker forks away the goods.

[0025] The support frame 3 includes a support base 31 and two longitudinally arranged support rod bodies 32 provided on the support base 31. Slide rails 33 are provided on the support rod bodies 32, and sliders 43 corresponding to the slide rails 33 are provided on the goods picking shelf 4. The double support rod bodies 32 and double slide rails 33 are arranged, and the operation is more stable. The support rod bodies 32 are located outside the conveyor line 1 and close to the conveyor line 1, saving space.

[0026] A first limit block 34 is provided on the support base 31, and a second limit block 35 is provided at the top of the slide rail 33. The first limit block 34 and the second limit block 35 respectively correspond to the lowest and highest positions of the movement of the goods picking shelf 4. The first limit block 34 and the second limit block 35 are used to limit the movement height of the goods picking shelf 4 to ensure the positioning accuracy of the lifting positions.

[0027] The goods picking shelf 4 includes a rectangular bottom frame 41 and two groups of goods picking supports 42 located on the bottom frame 41. The goods picking supports 42 are detachably connected to the bottom frame 41. The goods picking supports 42 pass through the gaps between adjacent conveying rollers 2 under the drive of the drive cylinder 5. The rectangular bottom frame 41 realizes stable support for the goods picking supports 42, and the goods picking supports are arranged at intervals without affecting the stacker in picking up goods.

[0028] A blocking mechanism 6 is further arranged on the mounting frame. The blocking mechanism 6 is higher than the conveying line 1 and is located on one side of the goods picking support 42. The blocking mechanism 6 includes a blocking plate 61 and a mounting rod 62 connected to the blocking plate 61. An adjusting hole 63 is arranged on the mounting rod 62, and the horizontal distance between the mounting rod 62 and the end of the conveying line 1 is adjustable.

[0029] The adjusting hole 63 can adjust the installation position of the blocking mechanism 6, increasing the flexibility of use. The blocking plate 61 is used to block the goods conveyed so that the goods stay at the picking position, ensuring that the goods picking shelf 4 can lift the goods stably, and thus facilitating the subsequent picking by the stacker.

[0030] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
