Description

Technical Field

[0001] This utility model relates to the field of logistics and conveying technology, and specifically to a rotary alignment conveying mechanism. Background Technology

[0002] Currently, in the field of automated logistics conveying, it is necessary to turn the conveyed items to meet the needs of sorting, scanning, and palletizing. In some existing technologies, the turning step uses clamps. The clamps lift and rotate the goods before placing them back on the conveyor. Although this method can achieve the turning of the goods, it applies clamping pressure to the goods, which can easily cause deformation of the outer packaging.

[0003] Patent application CN202320640958.1 discloses a transition steering conveyor, which includes: a lifting and rotating mechanism, a frame, a roller conveying mechanism, and photoelectric switches; the roller conveying mechanism includes a first geared motor and rollers, the first geared motor is installed inside the frame, and multiple rollers are arranged on the top of the frame along the conveying direction, the first geared motor is used to drive the rollers to rotate; the lifting and rotating mechanism includes a tray, a cylinder, and a second geared motor, the tray is arranged between the rollers, the cylinder and the second geared motor are installed inside the frame, the cylinder is used to drive the tray to lift and lower, and the second geared motor is used to drive the tray to rotate; the photoelectric switches are arranged on both sides of the frame along the conveying direction, and when the photoelectric switches detect that the rubber block passes over the tray, they can send a signal to control the first geared motor, the cylinder, and the second geared motor. In this technical solution, the goods are lifted and turned when passing the pallet, and then placed on the conveyor rollers to continue being transported downstream. The goods are not subjected to external pressure during the turning process, which solves the deformation problem caused by the clamps. However, in some cases, when converting the horizontally conveyed cuboid goods into vertically conveyed goods, the pallet area is limited and the center of gravity of the goods may not be exactly in the center. At this time, the center of gravity of the lifted goods may be unstable, resulting in tilting and other phenomena, which cause the turning step to not proceed as expected. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a rotary alignment conveying mechanism. This device causes less damage to goods during operation, prevents goods from being deformed due to clamping during rotational alignment, and provides better stability of goods during turning. It is particularly suitable for conveying cuboid goods whose center of gravity is off-center from the volume center.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary alignment conveying mechanism includes two parallel mounting rails, with a rotary alignment component, an inlet platform, and an outlet platform disposed between the two mounting rails. The inlet platform and outlet platform are respectively located upstream and downstream of the rotary alignment component. The rotary alignment component includes a mounting frame located in the middle, a lifting device connected to the mounting frame, a rotating device connected to the upper end of the lifting device, and a support plate connected to the rotating device. Movable supports are provided upstream and downstream of the rotary alignment component, and a lifting motor is connected to the lower end of each movable support. The upper surface of the movable support can move between a first limit plane and a second limit plane, and the upper surface of the support plate can move between a third limit plane and a fourth limit plane. The heights of the first and second limit planes do not exceed the upper surfaces of the inlet platform and the outlet platform, and the height of the second limit plane does not exceed the fourth limit plane.

[0010] Furthermore, a negative pressure adsorption head is provided on the upper side of the support plate, and the negative pressure adsorption head is located in the interval area between the support pads.

[0011] Furthermore, the negative pressure suction head includes a flexible suction cup, the upper surface of which is higher than the upper side surface of the support block.

[0012] Furthermore, the mounting rail is also connected to a photoelectric sensing component, which is located on the side of the rotation alignment component.

[0013] Furthermore, the import platform includes several import rollers, and the two ends of the import rollers are respectively connected to two mounting rails.

[0014] Furthermore, the export platform includes several export rollers, and the two ends of the export rollers are respectively connected to two mounting rails.

[0016] 1.

During the turning process, the goods will not be squeezed, which can avoid the deformation of the goods to a greater extent and reduce the damage to the goods.

[0017] 2. The rotating alignment component of this utility model has two movable supports at its upper and lower ends. The movable supports are used to provide auxiliary support when the goods are lowered, so as to avoid the goods from tilting due to instability of the center of gravity.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model. Example

[0025] Reference Figures 1-3This utility model provides a rotary alignment conveying mechanism, which includes two parallel mounting rails 1, a rotary alignment component 2 disposed between the two mounting rails, an inlet platform 3 and an outlet platform 4 disposed upstream and downstream of the rotary alignment component, respectively. The inlet platform includes a plurality of inlet rollers, the two ends of which are respectively connected to the two mounting rails. The outlet platform includes a plurality of outlet rollers, the two ends of which are respectively connected to the two mounting rails. The rotary alignment component includes a mounting frame 21, a lifting device 22 connected to the mounting frame, a rotary device 23 connected to the upper end of the lifting device, and a horizontal support for use connected to the rotary device. The support plate 24 is provided with a movable bracket 7 at one end near the upstream end and another end near the downstream end. The lower end of the movable bracket is connected to a lifting motor 71. The upper surface of the movable bracket can move between a first limit plane and a second limit plane. The upper side of the support plate can move between a third limit plane and a fourth limit plane. The height of the first limit plane and the second limit plane does not exceed the upper surface of the import platform and the export platform. The height of the second limit plane does not exceed the fourth limit plane. The side of the rotation alignment component is provided with a photoelectric sensing component 6 that is fixedly connected to the mounting rail. In the non-lifted state, the upper surface of the support plate is at the first limit position, allowing the cargo 8 to be transferred from the guide platform 3 to above the rotating alignment component 2. After the cargo reaches the predetermined position, the photoelectric sensing component is activated, and then the lifting motor 71 and the lifting device 22 are started, causing both the movable support 7 and the support plate 24 to begin to lift. However, the maximum lifting height of the upper surface of the movable support does not exceed the upper side of the support plate. Then, the rotating device 23 is started to turn the cargo. After the turning is completed, the lifting device 22 first resets, lowering the height of the cargo. When the upper side of the support plate is flush with the upper surface of the movable support, the lifting motor 71 begins to reset synchronously with the lifting device 22, so that the cargo is supported synchronously by the support plate and the two movable supports when it descends.

[0026] When converting horizontally conveyed cuboid goods into vertically conveyed goods, the goods may tilt and sway due to an unstable center of gravity. For some goods whose center of gravity does not coincide with the center of volume, the instability is more serious and may even cause the goods to slip off the support plate. This utility model sets a movable bracket at the upper and lower ends of the rotating alignment component. The vertically conveyed goods after rotation are supported by the support plate and the two movable brackets at the same time during the descent, which can play a role in stabilizing the support.

[0027] In a further embodiment, a transition platform 5 is provided on each side of the rotary alignment component 2. The transition platform includes several transition rollers. The mounting frame 21 has two vertical mounting plates 211. The two ends of the transition rollers are connected to the mounting rail and the vertical mounting plate, respectively. The transition platform can transfer the goods more stably above the rotary alignment component 2.

[0028] In one embodiment, the supporting surface of the supporting plate 24 can be circular. In this case, the supporting plate will not come into contact with other mechanisms during rotation, and the rotation of the supporting plate is more free. However, in this case, the arc edge of the supporting surface has a weaker limiting effect on the goods, making the goods more prone to instability. Therefore, in the preferred embodiment of this utility model, the supporting plate is set as rectangular to achieve a more stable supporting effect. However, if a transition platform 5 is provided, the supporting plate 24 and the transition platform 5 will conflict in position. In this case, another working method is adopted: after the goods are turned, the lifting device 22 first resets, so that the height of the goods is reduced until the goods are placed on the two movable supports. Then the lifting device continues to reset, and the rotating device begins to reset, storing the supporting plate in its original position. After the supporting plate is stored, the lifting motor 71 starts to reset again, placing the goods so that they can continue to be transported downstream. At this time, the supporting plate not only plays an auxiliary supporting role, but also plays an auxiliary role in resetting the rotating alignment component 2.

[0029] In a further embodiment, a plurality of support pads 241 are spaced apart on the upper side of the support plate, and a negative pressure adsorption head 242 is provided in the spaced area between the support pads. The negative pressure adsorption head has a flexible suction cup, and the upper end of the flexible suction cup is about 1 mm higher than the upper side of the support pad. The negative pressure adsorption head can make the goods more stably placed on the support plate.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
