Detailed Description

As shown in fig. 1, 2, 3, 4, and 5, the utility model provides an automatic carrier loading mechanism, the lifting machine includes a frame 1 and a chain 2. Install sprocket 3 on the frame 1, sprocket 3 is connected with the motor, and 2 vertical settings of chain are around establishing on sprocket 3, are cyclic motion by the sprocket drive. The chain 2 is provided with a goods delivering rack 4, and the goods delivering rack 4 is vertical to the surface of the chain wheel 3, so that the carrier hung on the goods delivering rack can not overturn in the lifting section or the descending section. The chain guide rail is characterized by further comprising a chain guide rail 6, wherein a wear-resistant strip 7 is arranged in the chain guide rail 6, and the chain 2 of the vertical section is arranged in the wear-resistant strip 7.

The automatic racking mechanism is positioned at the joint of the lifting section and the chain wheels, the chain is generally wound on the two chain wheels, if direction change is needed, the number of the chain wheels is more, one chain wheel 3 is shown in figure 1, and the guide rail 5 is positioned lower than the chain wheel 3. Guide rail 5 is towards chain 2, and the output of guide rail 5 is provided with the vertical groove of dodging that runs through, should dodge groove department one side or both sides and be equipped with fender point 8, blocks the carrier. The catch points 8 are located on both sides of the lifting channel of the goods presentation shelf 4. The goods delivering rack 4 moves upwards, and the suspended end passes through the avoiding groove from bottom to top, so that the carrier at the stop point 8 is taken away and hung on the goods delivering rack 4.

Referring to fig. 3 and 7, the vertical distance H from the stop point 8 to the highest point of the sprocket 3 should be less than or equal to the height H of the vertical portion of the carrier 9. If both equal, when the chain rotated to the sprocket peak, the carrier body of hanging on the delivery rack can touch the guide rail bottom, and the chain rotates the decline section afterwards, and the carrier follows and descends, does not influence whole operation. If H is less than height H, when the chain rotates to the highest point of the chain wheel, the carrier body can not touch the bottom of the guide rail. In both cases, the interference between the carrier body and the guide rail to influence the operation can be avoided when the carrier is lifted to the highest point of the chain wheel. The carrier shown in fig. 7 is a clothes rack, and comprises a clothes rack rod 9.1 and a clothes rack body 9.2, the clothes rack rod 9.1 is a vertical part, and the carrier can also be a carrier with other structures such as a hanging basket and the like, which are not described one by one. As shown in fig. 3, in the descending section, the chain is obliquely arranged towards the outer side of the sprocket from the highest point of the sprocket, so that the chain is obliquely downwards inclined from the highest point to the outer side, after the carrier is taken away from the guide rail 5 by the delivery rack 4, the carrier obliquely downwards moves via backward inclining from the highest point of the sprocket, so that the carrier is far away from the guide rail 5, and the interference with the guide rail due to the continuous upward movement is avoided, in fig. 3, the position below the middle part is a guide wheel, the chain 2 can be wound on the guide wheel (not shown in the figure), and the guide wheel is used for pulling the chain to be obliquely arranged towards the outer side of the sprocket 3, so that the chain 2 can obliquely downwards move.

Specifically, as shown in fig. 6, the output end of the guide rail 5 is connected with an extension portion 5.1, and the extension portion and the guide rail 5 may be integrated or separated. The avoidance groove and the stop point are arranged on the extension part 5.1. It should be noted that the extension portion shown in fig. 6 forms 2 plate-like structures on both sides of the avoiding groove, the utility model discloses in some application scenarios, the extension portion can only have one side plate-like structure, and when only setting up one side plate-like structure, the extension portion staggers with the goods delivery frame moving channel and just can not obstruct the goods delivery frame, has just naturally formed the utility model discloses in supply the avoiding groove that the goods delivery frame passes through.

As shown in fig. 6, the guide rail 5 is arranged obliquely, and the vehicle can slide down to the stop point 8 by gravity. A release mechanism 13 is installed upstream of the stop point 8, and a second carrier detection device 14 is installed at the release mechanism 13 and is used for detecting whether a carrier exists at the release mechanism 13. When the second carrier detection device 14 detects that a carrier is in the releasing mechanism 13, the releasing mechanism is controlled to release the carrier to the stopping point 8 at a certain interval, the releasing interval time needs to meet the condition that the carrier at the stopping point 8 is taken away by the goods delivering rack 4 when the carrier is released, and the releasing interval time is more than or equal to the interval between two goods delivering racks divided by the running speed of the chain.

The upper rack, namely the corresponding position of the output end of the guide rail 5, two sides of the goods delivery rack channel are provided with limiting blocks 15, the limiting blocks 15 are installed on two sides of the chain guide rail 6 through connecting plates 16, the guide rail 5 is installed on an L-shaped supporting piece 17, and the L-shaped supporting piece 17 is connected with one of the connecting plates, so that the assembling precision and the overall rigidity are improved.

As shown in fig. 5, annular grooves are formed at intervals along the length direction of the outer periphery of the delivery rack 4, and hooks of the carriers are hung in the annular grooves to prevent the carriers from falling off.
