[0002] In the field of cargo transportation, pallets are the medium that transforms static cargo into dynamic cargo. They are a cargo platform, and a movable platform, or a movable ground. Even cargo that loses flexibility when placed on the ground will immediately become active and become flexible mobile cargo once it is loaded on a pallet, because the cargo loaded on the pallet is always ready to be put into motion.

[0003] For example, the authorization announcement number "CN210048233U" is named as a guide device with adjustable spacing, which can be slidably fixed by a support rod and a support frame. Notches are set at both ends of the support rod. By turning the support rod with a handle, the distance between the notch and the limit block can be adjusted to achieve the adjustment of the spacing between the first main roller and the second main roller. It has a simple structure and is easy to operate. However, existing traditional logistics conveying lines are all equipped with guide devices, but these guide devices are usually not adjustable and cannot adapt to pallets of different models; in addition, common adjustable guides basically use linear slide rail assemblies to achieve the guiding function. When a stack of palletized goods accidentally falls and hits the linear slide rail assembly, it is easy to cause it to deform, resulting in the loss of the guiding adjustment function.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] Example 1:

[0020] See also Figure 1-5 : In this embodiment, a pallet guiding device with adjustable spacing includes a fixed frame 1, a conveying frame 2 and a pallet 3. The conveying frame 2 is fixedly installed on the top of multiple fixed frames 1. The conveying frame 2 includes a roller bracket 21 and a roller 22. The roller bracket 21 is fixedly connected to the top of the fixed frame 1. The inner side of the roller bracket 21 is rotatably connected to multiple rollers 22. The rollers 22 can rotate inside the roller bracket 21 to drive the pallet 3 to be placed and positioned. The pallet 3 is movably placed above the outer wall of the roller 22.

[0021] A guide adjustment assembly 4 is provided on both sides of the fixed frame body 1. The guide adjustment assembly 4 includes a connecting ear seat 41 and an oblique support 47. Multiple oblique supports 47 are fixedly connected to the inner side of the outer wall of the fixed frame body 1. Multiple connecting ear seats 41 are fixedly connected to the inner side of the top end of the fixed frame body 1. The front ends of the two connecting ear seats 41 are rotatably connected to two driving electric cylinders 42. The model of the driving electric cylinder 42 can be selected to meet the use requirements.

[0022] The front end of the driving electric cylinder 42 can pull the electric cylinder working rod 43 to extend or shorten. The front ends of the two driving electric cylinders 42 are slidingly connected to the two electric cylinder working rods 43. The front ends of the two electric cylinder working rods 43 are rotatably connected to the two connecting ear seats 44. When the size of the pallet 3 passing through the conveyor rack 2 changes and the pallet guide 45 needs to make corresponding adjustments, the driving electric cylinder 42 is started and the pallet 3 is guided to be pushed outward or retracted inward through the electric cylinder working rod 43.

[0023] Since the driving electric cylinder 42 is rotatably connected to the fixed frame 1 through the connecting ear seat 1 41, and the electric cylinder working rod 43 is rotatably connected to the tray guide 45 through the connecting ear seat 2 44, the tray guide 45 will not interfere with the roller bracket 21 due to the installation level of the driving electric cylinder 42. The tray guide 45 is fixedly connected to the other side of the outer wall of the two connecting ear seats 44, and the two ends of the tray guide 45 are fixedly connected to the inclined guide 451. The front end of the outer wall of the tray guide 45 is arranged opposite to the two sides of the outer wall of the tray 3.

[0024] Sliding limit assemblies 46 are provided on both sides of the top of the fixed frame 1. The sliding limit assemblies 46 include a sliding box 461 and a lower limit plate 465. Multiple lower limit plates 465 are fixedly connected to both sides of the top of the fixed frame 1. The lower end of the lower limit plate 465 is fixedly connected to the top of the inclined support 47. The lower end of the lower limit plate 465 is fixedly connected to the inclined support 47 to support the end away from the fixed frame 1. The upper end surface of the lower limit plate 465 is fixedly provided with a limiting slide groove 4651.

[0025] When the tray guide 45 moves, the rectangular tube 466 fixedly connected to its outer ends moves synchronously. The upper end surface of the lower limit plate 465 is provided with a limit slide groove 4651. The rectangular tube 466 slides in the limit slide groove 4651 through the limit slide rail 4661. The lower end surface of the upper limit plate is flush with the upper end surface of the rectangular tube 466. The upper limit plate 464 and the lower limit plate 465 jointly limit the rectangular tube 466 to slide only in the horizontal direction. The limit slide rail 4661 is slidably connected to the inside of the limit slide groove 4651, and the rectangular tube 466 is fixedly connected to the limit slide rail 4661.

[0026] A sliding box 461 is fixedly connected to the inner side of the rectangular tube 466, and a limiting roller 1 462 and a limiting roller 2 463 are provided on the inner side of the sliding box 461. The lower ends of the limiting roller 1 462 and the limiting roller 2 463 are rotatably connected to the lower limiting plate 465 respectively. The limiting roller 1 462 and the limiting roller 2 463 are staggered in the sliding box 461. The limiting roller 1 462 rolls against the inner end surface of the sliding box 461 close to the driving electric cylinder 42, and the limiting roller 2 463 rolls against the inner end surface of the sliding box 461 away from the driving electric cylinder 42. The upper ends of the limiting roller 1 462 and the limiting roller 2 463 are rotatably connected to the upper limit plate 464 respectively, and the lower end surface of the upper limit plate 464 is flush with the upper end surface of the rectangular tube 466.

[0027] When the sliding box 461 moves with the rectangular tube 466, the limiting roller 1 462 and the limiting roller 2 463 rotate. When the tray 3 squeezes the inclined guides 451 at both ends of the tray guide 46, causing the tray guide 45 to deflect around the connecting ear seat 2 44 in the horizontal plane, the staggered limiting rollers 1 462 and 2 463 will generate a reaction force on the end face of the sliding box 461, limiting the deflection of the sliding box 461, the rectangular tube 466 and the tray guide 45, thereby ensuring that the guiding direction of the tray guide 45 will not deflect.

[0028] Working principle:

[0029] The pallet guide device with adjustable spacing is mainly used for guiding and adjusting pallets of different sizes when carrying goods through the conveyor rack. By providing a guide adjustment component 46, the guide function of pallets 3 of different sizes passing through the conveyor rack 2 is achieved, expanding the application scenarios of pallet guidance. By staggering the limiting rollers 1 462 and 2 463, and cooperating with the sliding box 461, the horizontal deflection of the pallet guide 45 is limited.

[0030] First, when the size of the pallet 3 passing on the conveyor frame 2 changes and the pallet guide 45 needs to be adjusted accordingly, the driving electric cylinder 42 is activated, and the pallet guide 45 is pushed outward or retracted inward via the electric cylinder working rod 43. Since the driving electric cylinder 42 is rotatably connected to the fixed frame 1 via the connecting ear seat 1 41, and the electric cylinder working rod 43 is rotatably connected to the pallet guide 45 via the connecting ear seat 2 44, the pallet guide 45 will not interfere with the roller bracket 21 due to the horizontal installation of the driving electric cylinder 42.

[0031] Then, when the tray guide 45 moves, the rectangular tube 466 fixedly connected to its outer ends moves synchronously, and the lower end of the lower limit plate 465 is fixedly connected to the oblique support 47 to support the end away from the fixed frame 1. The upper end surface of the lower limit plate 165 is provided with a limiting slide groove 4651, and the rectangular tube 466 slides in the limiting slide groove 4651 through the limiting slide rail 4661. The upper ends of the limiting roller 1 462 and the limiting roller 2 463 are respectively rotatably connected to the upper limit plate 464, and the lower end surface of the upper limit plate is flush with the upper end surface of the rectangular tube 466. The upper limit plate 464 and the lower limit plate 465 jointly limit the rectangular tube 466 to slide only in the horizontal direction;

[0032] The limiting roller 1 462 and the limiting roller 2 463 are staggered in the sliding box 461. The limiting roller 1 462 rolls and abuts against the inner end surface of the sliding box 461 on the side close to the driving electric cylinder 42, and the limiting roller 2 463 rolls and abuts against the inner end surface of the sliding box 461 on the side away from the driving electric cylinder 42. When the sliding box 461 moves with the rectangular tube 466, the limiting roller 1 462 and the limiting roller 2 463 rotate. When the tray 3 squeezes the inclined guide 451 at both ends of the tray guide 46, causing the tray guide 45 to deflect around the connecting ear seat 2 44 in the horizontal plane, the staggered limiting roller 1 462 and the limiting roller 2 463 will generate a reaction force on the end surface of the sliding box 461, limiting the deflection of the sliding box 461, the rectangular tube 466 and the tray guide 45, thereby ensuring that the guiding direction of the tray guide 45 will not deflect.
