A material unloading device for logistics transportation

Abstract

This utility model relates to the technical field of unloading equipment, specifically an unloading device for logistics transportation, comprising: a first conveyor and a second conveyor. A conveyor roller is installed obliquely between the first and second conveyors. A connecting frame is installed between the two ends of the first conveyor. A detection component is provided on the top of the connecting frame, and a wear-reducing unloading mechanism is provided at one end of the connecting frame. This utility model uses a multi-stage electric cylinder to extend a long frame, and the positive and negative threaded rods rotate, bringing two semi-hollow boxes closer together to clamp the sides of the package. Then, a vacuum pump is activated to generate negative pressure in the negative pressure holes, increasing the clamping effect. Next, the lifting plate driven by the lifting electric cylinder rises, causing the package to leave the first conveyor. Finally, the multi-stage electric cylinder continues to extend the long frame, moving the package above the conveyor roller. The clamping of the package is then released, and the package rolls on the conveyor roller onto the second conveyor to complete the transport. This process reduces wear on the bottom of the package.

Description

Technical Field

[0001] This utility model relates to the technical field of unloading equipment, specifically an unloading device for logistics transportation. Background Technology

[0002] When express parcels are transported on conveyor belts, they usually need to be separated into different heights. During the temporary storage or storage stage, parcels are stored separately according to their height. This can make better use of storage space and avoid situations where large spaces are wasted by small parcels or small parcels are difficult to find in large spaces.

[0003] In existing technologies, packages that are higher on the conveyor belt are generally unloaded by using a cylinder and a pusher plate. The cylinder is installed at one end of the conveyor belt, and the cylinder drives the pusher plate to extend. The pusher plate pushes the package to move on the conveyor belt. Since the conveyor belt has a certain width, the package needs to move a certain distance on the conveyor belt before it can leave the conveyor belt and be unloaded. The friction between the package and the conveyor belt is relatively large, which can easily cause wear on the bottom of the package and increase the customer return rate.

[0004] Therefore, this utility model designs an unloading device for logistics transportation to solve the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this utility model is to provide an unloading device for logistics transportation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material unloading device for logistics transportation, comprising: a first conveyor and a second conveyor, wherein a conveying roller is obliquely installed between the first conveyor and the second conveyor, a connecting frame is installed between the two ends of the first conveyor, a detection component is provided on the top of the connecting frame, and a material unloading mechanism that can reduce wear is provided at one end of the connecting frame.

[0007] Preferably, the detection component includes an adjusting electric cylinder, which is mounted on the top of the connecting frame. The output end of the adjusting electric cylinder is connected to a connecting plate. Both ends of the bottom of the connecting plate are equipped with mounting columns. An infrared generator and an infrared receiver are respectively provided at one end of the two mounting columns close to each other. When the express parcel is transported on a conveyor, when a taller parcel passes between the infrared generator and the infrared receiver, the signal emitted by the infrared generator is blocked, and the infrared receiver can no longer receive the signal, thus detecting the taller parcel.

[0008] Preferably, the unloading mechanism includes a long plate installed below one end of the connecting frame. A lifting electric cylinder is installed at the bottom of the long plate, and a lifting plate is connected to the output end of the lifting electric cylinder. A multi-stage electric cylinder is installed at one end of the lifting plate, and a clamping assembly is provided at the output end of the multi-stage electric cylinder. The multi-stage electric cylinder drives the long frame to extend, and the positive and negative threaded rods rotate to bring the two semi-hollow boxes closer together to clamp the sides of the package. Then, the vacuum pump is started to generate negative pressure in the negative pressure hole to increase the clamping effect. Then, the lifting plate driven by the lifting electric cylinder rises, causing the package to leave the first conveyor. Finally, the multi-stage electric cylinder continues to drive the long frame to extend, moving the package above the conveyor roller. Then, the clamping of the package is released, and the package can roll on the conveyor roller to the second conveyor to complete the conveying. During the conveying process, the wear on the bottom of the package is reduced, and the customer return rate is reduced.

[0009] Preferably, the clamping assembly includes a long frame, which is fixedly installed to the output end of a multi-stage electric cylinder. Positive and negative threaded rods are rotatably installed between the two sides of the long frame. Semi-hollow boxes are slidably installed on the outer side walls of both sides of the positive and negative threaded rods through threads. When the positive and negative threaded rods are rotated, the two semi-hollow boxes can be brought closer to each other, thereby clamping the two sides of the package.

[0010] Preferably, each of the two semi-hollow boxes has several negative pressure holes on one side close to each other. An air pump is connected to each semi-hollow box. Half of the semi-hollow box is hollow, and the negative pressure holes are opened in the hollow part. By starting the air pump, the negative pressure holes are generated, which can adsorb and wrap, and improve the clamping effect.

[0011] Preferably, a guide rod is fixedly installed between the two sides of the long frame, and the semi-hollow box and the guide rod are slidably connected, with the guide rod limiting the semi-hollow box.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a multi-stage electric cylinder to extend a long frame, and the positive and negative threaded rods rotate to bring the two semi-hollow boxes closer together, clamping the sides of the package. Then, the vacuum pump is activated to create negative pressure in the negative pressure holes, increasing the clamping effect. Next, the lifting plate driven by the lifting electric cylinder rises, causing the package to leave the first conveyor. Finally, the multi-stage electric cylinder continues to extend the long frame, moving the package above the conveyor roller. Then, the clamping of the package is released, and the package can roll on the conveyor roller onto the second conveyor to complete the transport. During the transport process, wear on the bottom of the package is reduced, thus reducing the customer return rate. Attached Figure Description

[0020] Please see Figure 1-3 In this embodiment: the detection component 5 includes an adjusting electric cylinder 501, which is installed on the top of the connecting frame 4. The output end of the adjusting electric cylinder 501 is connected to a connecting plate 502. Both ends of the bottom of the connecting plate 502 are equipped with mounting posts 503. An infrared generator 504 and an infrared receiver 505 are respectively provided at one end of the two mounting posts 503 that are close to each other.

[0021] Please see Figure 1-3 In this embodiment: the unloading mechanism 6 includes a long plate 601, which is installed below one end of the connecting frame 4. A lifting electric cylinder 602 is installed at the bottom of the long plate 601. The output end of the lifting electric cylinder 602 is connected to a lifting plate 603. A multi-stage electric cylinder 604 is installed at one end of the lifting plate 603. A clamping assembly 605 is provided at the output end of the multi-stage electric cylinder 604.

[0022] Please see Figure 1-3In this embodiment: the clamping assembly 605 includes a long frame 6051, which is fixedly installed with the output end of the multi-stage electric cylinder 604. A positive and negative threaded rod 6052 is rotatably installed between the two sides of the long frame 6051. A semi-hollow box 6053 is slidably installed on both outer walls of the positive and negative threaded rod 6052 through threads. One side of the positive and negative threaded rod 6052 is connected to the output end of the servo motor.

[0023] Please see Figure 1-3 In this embodiment: two semi-hollow boxes 6053 are provided with several negative pressure holes 6054 on one side close to each other. A vacuum pump 6055 is connected to the semi-hollow box 6053. The interior of the semi-hollow box 6053 is generally a hollow structure. The vacuum pump 6055 is connected to the hollow part, and the negative pressure holes 6054 are also provided in the hollow structure.

[0025] Working principle: Express parcels are transported on conveyor 1. When a tall parcel passes between infrared generator 504 and infrared receiver 505, the signal emitted by infrared generator 504 is blocked. Since infrared receiver 505 cannot receive the signal, the controller transmits the signal to multi-stage electric cylinder 604. Multi-stage electric cylinder 604 drives the long frame 6051 to extend. Then, the positive and negative threaded rods 6052 rotate, causing the two semi-hollow boxes 6053 to move closer together, clamping the parcel on both sides. Finally, lifting electric cylinder 602 drives the lifting plate 603 to rise a certain distance. The package is then removed from conveyor 1. Finally, the multi-stage electric cylinder 604 continues to drive the long frame 6051 to extend, moving the package above the conveyor roller 3. The positive and negative threaded rods 6052 rotate in the opposite direction, causing the semi-hollow box 6053 to release its grip on the package. The package can then roll off the conveyor roller 3 onto conveyor 2 for continued transport, achieving unloading of taller packages. Since the package does not need to rub against conveyor 1 during unloading, wear on the bottom of the package is reduced. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
