Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise stated, the terms of orientation such as "upper", "lower", "top" and "bottom" are generally defined according to the normal use state of the storage rack, and refer to the drawing directions shown in fig. 2 and 3; "inner" and "outer" refer to the inner and outer contours of the respective components. Furthermore, the terms "first," "second," and the like, as used in this disclosure, are intended to distinguish one element from another, and not necessarily for order or importance. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated.

Referring to fig. 1 to 3, the present disclosure provides a goods taking rack including a first rack main body 110 and a first supporting portion 120 for receiving and taking goods from a cargo way, the first supporting portion 120 having a first end portion capable of being butted against the cargo way and a second end portion opposite to the first end portion to receive the goods from the cargo way through the first end portion. Wherein the first support part 120 is rotatably coupled to the first frame body 110 up and down so that the goods can be moved obliquely downward on the first support part 120. The first supporting portion 120 can rotate up and down relative to the first frame body 110 in various ways, for example, the first supporting portion 120 can be connected to a driving shaft to directly drive the first supporting portion 120 to rotate up and down synchronously through the rotation of the driving shaft, wherein the driving shaft can be connected to any position of the first supporting portion 120, and it is only necessary to ensure that the first supporting portion 120 can tilt down and the goods can be stably supported on the first supporting portion 120. For example, a support rod may be disposed at a position below the first support 120, and the first support 120 may rotate up and down around a certain point by linear movement of the support rod, so as to tilt down the first support 120.

Further, as an embodiment, after the goods reach above the first supporting portion 120, the goods may be carried out of the take-out rack through the second end portion. For example, when the first support portion 120 is rotatably coupled to the first rack body 110, the rotation of the first support portion 120 with respect to the first rack body 110 may be performed such that the second end portion is lower than the first end portion in the horizontal level, so that the goods may slide from the lane onto the first support portion 120 by its own weight or be transferred from the first support portion 120 to the rack by the second end portion. In another embodiment, after the goods reach above the first supporting portion 120, the goods may be carried out from the rack through the first end portion. For example, when the first support part 120 is rotatably coupled to the first rack main body 110, the first support part 120 may be rotated with respect to the first rack main body 110 at the time of receiving goods such that the second end is lower than the first end in level, so that goods may slide from the cargo way onto the first support part 120 by its own weight; the rotation of the first support 120 with respect to the first rack body 110 during unloading is performed such that the second end portion is higher in level than the first end portion, so that the goods can be transferred from the first support 120 through the first end portion by its own weight to take out the rack.

The present disclosure does not limit the structural form of the first supporting part 120, the first supporting part 120 may have a continuous plane for carrying goods, the first end part and the second end part may be two ends of the plane, respectively, and the first end part and the second end part not at the same horizontal height may be understood as the plane having a certain inclination angle with respect to the horizontal plane. For example, in the embodiment where the first support 120 is configured as a simple support plate, the upper surface of the support plate can be used for carrying and transporting goods, and the two opposite ends of the support plate with different horizontal heights are the first end and the second end. In addition, the first supporting portion 120 in the embodiment of the disclosure can also realize forward and reverse rotation (clockwise and counterclockwise) to satisfy different working modes or switch between different working modes. Next, a description will be given of an example in which the load enters the pickup rack from the first end and the pickup rack is carried out from the second end.

When the first supporting portion 120 is in a normal state (i.e., a non-working state), a continuous bearing portion between the first end portion and the second end portion may form a first inclination angle with a horizontal plane; when the first supporting part 120 is in the first working state (i.e., the cargo receiving state), a second inclination angle may be formed between the continuous bearing part between the first end part and the second end part and the horizontal plane, wherein the second inclination angle may be smaller than the first inclination angle, so that the cargo can be slowly moved from the cargo way to the first supporting part 120; when the first supporting portion 120 is in the second working state (i.e. the unloading state), a third inclination angle may be formed between the continuous bearing portion between the first end portion and the second end portion and the horizontal plane, wherein the third inclination angle may be larger than the first inclination angle, so that the goods can be quickly transferred out of the first supporting portion 120 to get out of the rack, and the third inclination angle is set to ensure that the goods do not collide with each other when being transferred out of the rack. In this way, when the goods taking rack receives goods, the first supporting portion 120 can rotate towards a first direction, and when the goods taking rack unloads goods, the first supporting portion 120 can rotate towards a second direction opposite to the first direction, so that the forward and reverse rotation of the first supporting portion 120 is realized. Meanwhile, the first supporting portion 120 can rotate in the forward and reverse directions, and the requirement for adjusting the inclination angle in real time can be met, so that various problems in the working process of the goods taking frame can be solved. The above example is only one application of the structure of the embodiment of the present disclosure, and in practical use, the first supporting portion 120 may be controlled by different control logics according to the picking and placing requirements of the goods, which are not described herein.

It should be noted that, the first frame main body 110 is used as a mounting and carrying carrier of the first supporting portion 120, and a certain distance may be formed between the first frame main body and the top and bottom of the first supporting portion 120, so as to satisfy the requirement of the first supporting portion 120 for forward or reverse rotation.

Meanwhile, when the goods taking rack is unloaded, the inclination angle of the first supporting part 120 relative to the first rack main body 110 can be adjusted again, so that the goods are transported out of the goods taking rack in a sliding manner by means of the self gravity, and the unloading efficiency is improved.

According to some embodiments, referring to fig. 2 and 3, the goods-taking rack may further include a first barrier 130 disposed adjacent to the second end for temporarily confining goods above the first support 120 to prevent the goods from being transported out of the first support 120 from the second end. Wherein, in case the second end portion is formed as a discharge end for carrying out the goods, the first flap 130 may be configured to be movable with respect to the first support part 120 so that the first flap 130 has an open position and a closed position. When the first flap 130 is in the open position, the goods on the first support 120 can be transferred out of the rack; when the first flap 130 is in the closed position, the goods on the first support 120 can be stopped in the goods shelf. Thus, when goods need to be temporarily stored in the goods taking shelf, the first baffle 130 can be enabled to be in the closed position; when the goods need to be removed from the take-off shelf, the first flap 130 may be caused to be in the open position to allow the goods to be transported out of the take-off shelf.

Here, the first flap 130 may be configured to be movable up and down, left and right, or rotated with respect to the first support part 120, so that the first flap 130 provides an escape space in a transferring direction of the goods when located at the open position, thereby allowing the goods to be carried out of the goods shelf. For example, when the goods taking rack provided by the embodiment of the present disclosure is used in the unmanned goods sorting system, the first support portion 120 may be opposite to a conveyor belt beside the goods taking rack or a transfer trolley for transferring goods, so that the goods on the first support portion 120 can be transferred from the inside of the goods taking rack to the conveyor belt beside the goods taking rack or the transfer trolley for transferring goods when the first flap 130 is in the open position.
