Description

Technical Field

[0001] The utility model relates to the technical field of tray transportation, in particular to a two-way tray limiting and diverting device. Background Art

[0002] With the rapid development of logistics automation, different specifications of trays need to be transported on the same conveyor line. Common trays in the prior art include large-sized trays with a three-way bottom and small-sized trays with a four-way bottom. To meet the needs of large trays, the conveyor line often has a relatively large lateral width. However, for small trays, their positions on the conveyor line may deviate. Therefore, a device is needed to limit the position of the trays with a smaller width in the middle of the conveyor line. This device can limit the position of the smaller trays while not affecting the transportation of large trays. Content of the Utility Model

[0003] Other features and advantages of the utility model will be described in the following specification, and will become apparent in part from the specification, or be understood by implementing the utility model. The objectives and other advantages of the utility model can be achieved and obtained through the structures specifically pointed out in the specification and other specification drawings.

[0004] The objective of the utility model is to overcome the above deficiencies and provide a two-way tray limiting and diverting device. By arranging a rotatable limiting component on the side of the two-way conveyor line, it is used to limit the position of small trays so that they are located in the middle of the conveyor line without affecting the normal transportation of large trays. When the small tray drops to the middle section of the conveyor line, the conveyor line drives it to transport to the right. Due to the auxiliary position adjustment of the rotating baffle on the side, the small tray can be located in the middle position of the conveyor line, playing a role in limiting and rectifying. When the large tray drops to the middle section of the conveyor line, the conveyor line drives it to transport to the left. During the transportation process, the rotating baffle will rotate with the tray, so it can not affect its transportation when the tray passes. After the transportation of the large tray is completed, the rotating baffle returns to its original position for the next tray transportation.

[0005] The utility model provides a two-way tray limiting and diverting device, which includes a two-way conveying line provided with several chain-type conveyors and a limiting component arranged on the side of the two-way conveying line; the limiting component includes a fixed seat, a rotating baffle and a positioning plate. The limiting component is fixed to the side of the two-way conveying line through the fixed seat. The fixed seat is provided with the axially rotating rotating baffle. One side of the rotating baffle is provided with the positioning plate, and at least one limiting component is arranged on the side of the two-way conveying line. The two-way conveying line provided with several chain-type conveyors is used for transporting trays. The assembly line that can transport in two directions enables two types of trays of different sizes to be diverted, realizing efficient transportation. The arranged limiting component is used to adjust the position of the small tray after it falls. The rotating baffle remains vertical under the action of the positioning plate and its own weight, so that the small tray falling from above fits against one side of the rotating baffle, enabling it to be located at the center of the conveying line and be smoothly output. It should be understood that for the two-way output of the two types of trays of different sizes by the two-way conveying line, information can be obtained through a detection component. When the detection software detects the size of the falling tray, the conveying line is driven to run in different directions, and trays of different sizes can be output at the left and right ends. Since the specific program of the detection component has nothing to do with the specific structure of this application, it will not be elaborated here.

[0006] In some embodiments, the limiting component further includes a stud, a nut, a spacer sleeve, a gasket and a spring washer. The rotating baffle is also provided with a fixing hole. The stud passes through the fixing hole and the fixed seat to fix the fixed seat and the rotating baffle to the side of the two-way conveying line. Nuts are screwed at both ends of the stud. The spacer sleeve, the gasket and the spring washer are sequentially clamped between the rotating baffle and the nut. The cooperation of the stud and the nut is used to fix the fixed seat and the rotating baffle to the side of the two-way conveying line. The added spacer sleeve, gasket and spring washer enable the rotating baffle to have a certain amount of movement space under the fixation of the nut, so that it can rotate freely clockwise or counterclockwise.

[0007] In some embodiments, an opening pin is further arranged at the end of the stud, and the opening pin is located outside the nut. The arranged opening pin is used to limit the position of the nut to prevent the nut from loosening and falling off. The specific fixing method of the opening pin can refer to the prior art.

[0008] In some embodiments, the rotating baffle includes an upper end and a lower end. The upper end is provided with an arc-shaped bend, and the weight of the lower end of the rotating baffle is greater than that of the upper end. When the large tray with a "川" - shaped bottom falls to the middle section of the conveying line, the conveying line drives it to transport to the left. During the transportation process, when the arc-shaped bend of the rotating baffle touches the bottom surface of the "川" - shaped tray, it will rotate and level with the tray, so it will not affect its transportation when the tray passes. After the transportation of the large tray is completed, due to the different weights at both ends of the rotating baffle, under the influence of the larger mass at the lower end, the rotating baffle will rotate clockwise to achieve automatic reset and continue to transport the next tray.

[0009] In some embodiments, the positioning plate is L-shaped, the back side of the L-shaped positioning plate is fitted on the fixing seat, and the lower end of the rotating baffle is in contact with the L-shaped positioning plate. During the automatic resetting process, under the influence of gravity, the rotating baffle will swing. The L-shaped positioning plate plays a blocking role during the resetting process of the rotating baffle to prevent it from swinging excessively and limit it to maintain a vertical state, so that when the small pallet falls onto the conveyor belt, the position of the pallet can continue to be adjusted.

[0010] In some embodiments, a first guide plate assembly is disposed outwardly on both sides of the bidirectional conveyor line, and the first guide plate assembly includes a long guide plate and a short guide plate, the long guide plate and the short guide plate are respectively located on both sides of the bidirectional conveyor line, and the limit assembly is located on the inner side of the long guide plate. The first guide plate assembly is used to adjust the position of the large pallet. When the large pallet just starts to fall, one side is close to the long guide plate. During the transportation to the left side, with the assistance of the short guide plate, the large pallet can be output in the middle of the conveyor line.

[0011] In some embodiments, the spacing between the long guide plate and the short guide plate is adapted to the size of the pallet. The first guide plate assembly is used to limit the transport of the large pallet, so the spacing of the first guide plate assembly is adapted to the size of the large pallet, and accordingly, the long guide plate is located outside the rotating baffle, and the two operate independently, and the long guide plate will not affect the normal operation of the rotating baffle.

[0012] In some embodiments, a second guide plate assembly is further provided on the outside of the bidirectional conveyor line, the first guide plate assembly is provided at the left end of the bidirectional conveyor line, and the second guide plate assembly is provided at the right end of the bidirectional conveyor line. The first guide plate assembly and the second guide plate assembly respectively provided at both ends of the conveyor line are used for guiding and transporting two pallets of different sizes.

[0013] In some embodiments, the second guide plate assembly includes two small guide plates, which are respectively located on both sides of the bidirectional conveyor line, and the spacing between the two small guide plates is adapted to the size of the pallet. The small guide plates are used to guide the small pallets, and the orientation of the small guide plates is adapted to the output direction of the small pallets on the bidirectional conveyor line. Similarly, the spacing between the two small guide plates is also adapted to the size of the small pallets.

[0014] In some embodiments, the front and rear ends of the long guide plate, the short guide plate and the small guide plate are all provided with arc openings. The enlarged openings are designed at both ends of the long guide plate, the short guide plate and the small guide plate so that the tray can smoothly enter the guide plate assembly and play a rectifying and guiding role on the tray so that it can be neatly output.

[0015] By adopting the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model sets a rotatable limiting component on the side of the bidirectional conveyor line to limit the small pallet, so that it is located in the middle of the conveyor line without affecting the normal transportation of the large pallet. When the small pallet falls to the middle section of the conveyor line, the conveyor line drives it to the right side for transportation. The rotating baffle on the side assists in position adjustment so that the small pallet can be located in the middle of the conveyor line, which plays a limiting and rectifying role. When the large pallet falls to the middle section of the conveyor line, the conveyor line drives it to the left side for transportation. During the transportation, the rotating baffle rotates with the pallet, so it will not affect the transportation of the pallet when it passes by. After the transportation of the large pallet is completed, the rotating baffle returns to its original position to transport the next pallet.

[0017] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure.

[0041] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of a bidirectional conveyor line in some embodiments of the utility model when transporting a large pallet.

[0042] According to some embodiments of the present utility model, the present utility model provides a two-way tray limiting and diverting device, including a two-way conveying line 1 provided with several chain-type conveyer belts and a limiting component 2 arranged on the side of the two-way conveying line 1; the limiting component 2 includes a fixed seat 21, a rotating baffle 22 and a positioning plate 23. The limiting component 2 is fixed to the side of the two-way conveying line 1 through the fixed seat 21. The fixed seat 21 is provided with the axially rotating rotating baffle 22. The positioning plate 23 is arranged on one side of the rotating baffle 22. At least one limiting component 2 is arranged on the side of the two-way conveying line 1. The two-way conveying line 1 provided with several chain-type conveyer belts is used for transporting trays. The conveyer line that can transport in two directions enables two trays of different sizes to be diverted, achieving efficient transportation. The provided limiting component 2 is used to adjust the position of the small tray after it falls. The rotating baffle 22 maintains a vertical state under the action of the positioning plate 23 and its own weight, so that the side of the small tray falling from above fits against the rotating baffle 22, enabling it to be located at the center of the conveying line and be smoothly output. It should be understood that for the two-way output of the two trays of different sizes by the two-way conveying line 1, information can be obtained through a detection component. When the detection software detects the size of the falling tray, the conveying line is driven to run in different directions, and trays of different sizes can be output at the left and right ends. Since the specific program of the detection component has nothing to do with the specific structure of this application, it will not be elaborated here.

[0043] The rotating baffle 22 includes an upper end and a lower end. The upper end is provided with an arc-shaped bend. The weight of the lower end of the rotating baffle 22 is greater than that of the upper end. When the large tray with a U-shaped bottom falls to the middle section of the conveying line, the conveying line drives it to transport to the left. During the transportation process, the arc-shaped bend of the rotating baffle 22 will rotate and level with the tray when it touches the U-shaped bottom surface. Therefore, it can not affect the transportation of the tray when the tray passes. After the transportation of the large tray is completed, due to the different weights at both ends of the rotating baffle 22, under the influence of the larger mass at the lower end, the rotating baffle 22 will rotate clockwise to achieve automatic reset and continue to transport the next tray.

[0044] On both sides of the two-way conveying line 1, a first guide plate combination 3 is arranged outward. The first guide plate combination 3 includes a long guide plate 31 and a short guide plate 32. The long guide plate 31 and the short guide plate 32 are respectively located on both sides of the two-way conveying line 1. The limiting component 2 is located inside the long guide plate 31. The provided first guide plate combination 3 is used to adjust the position of the large tray. When the large tray starts to fall, one side closely adheres to the long guide plate 31. During the transportation to the left, with the assistance of the short guide plate 32, the large tray can be output in the middle of the conveying line.

[0045] The spacing between the long guide plate 31 and the short guide plate 32 is adapted to the size of the pallet. The first guide plate assembly 3 is used to limit the transport of the large pallet, so the spacing between the first guide plate assembly 3 is adapted to the size of the large pallet, and accordingly, the long guide plate 31 is located outside the rotating baffle 22, and the two operate independently, and the long guide plate 31 will not affect the normal operation of the rotating baffle 22.

Similarly, the distance between the two small guide plates 41 is also adapted to the size of the small pallets.

[0050] The long guide plate 31, the short guide plate 32 and the small guide plate 41 are all provided with arc-shaped openings at both ends.
