Description

Technical Field

[0001] The utility model relates to the technical field of logistics sorting, in particular to a logistics line conveyor frame. Background Art

[0002] The initial form of logistics sorting was mainly manual and required only a small investment in equipment. However, with the development of e-commerce, the order sorting volume has increased rapidly, the delivery routes have increased, and the demands for labor costs, delivery processing speed, management efficiency and user experience have changed. Pure manual sorting cannot meet the requirements of large-scale distribution, so a logistics line conveyor rack has evolved.

[0003] According to the search, the Chinese Patent Network with patent number CN220049016U published "a logistics sorting device", which shields oversized logistics pieces by setting a shielding plate. The logistics pieces will squeeze the control button, causing the electric telescopic rod to extend and drive the push plate to move forward. The push plate will push the logistics pieces on the sorting conveyor belt to move and push the oversized logistics pieces out, so that the oversized logistics pieces can be easily sorted out without manual sorting of the oversized pieces. However, because the conveyor belt keeps conveying when the electric telescopic rod pushes out the oversized logistics pieces, when the oversized logistics pieces are intercepted, the subsequent logistics pieces are also intercepted here. In the process of the oversized logistics pieces being pushed away, the interception resistance in front of the subsequent logistics pieces begins to disappear from the side close to the electric telescopic rod. The side where the interception resistance disappears will be affected by the conveyor belt and undergo a certain displacement, causing the logistics pieces to deviate and no longer move neatly along the center of the conveyor belt. It is possible that the express delivery bill leaves the scanning range of the sorting camera. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a logistics line conveyor rack to solve the technical problem that the existing logistics line conveyor rack has no auxiliary blocking device when sorting oversized logistics items, which leads to the process of pushing away the oversized logistics items, affecting the placement position of subsequent logistics items.

[0006] By adopting the above technical scheme, the transmission interception mechanism is set up, after the oversized logistics pieces are successfully intercepted by the interception plate, before the subsequent logistics pieces move to this place, the baffle plate can be extended between the two adjacent transmission rollers on the rear side of the moving direction of the oversized logistics pieces, and before the oversized logistics pieces are pushed off the conveyor frame body by the second electric push rod and the push plate, the subsequent logistics pieces can be prevented from being displaced by the transmission rollers, and the occurrence of uneven interception resistance can be eliminated, ensuring that the subsequent normal logistics pieces will not be offset due to the sorting process of the oversized logistics pieces.

[0007] Furthermore, the first screw is fixedly connected to the first motor, the intercepting plate is threadedly connected to the first screw, and the intercepting plate is slidably connected to the U-shaped frame.

[0008] By adopting the above technical solution, when the first motor is started, it drives the first screw rod fixedly connected thereto to rotate, and the intercepting plate moves up and down under the action of the threaded connection between the intercepting plate and the first screw rod, and the sliding connection between the intercepting plate and the U-shaped frame.

[0009] Furthermore, the second motor is fixedly connected to the second screw rod, the second screw rod is threadedly connected to the first movable plate, and the first movable plate is slidably connected to the limiting rod.

[0010] By adopting the above technical solution, when the second motor is started, it drives the second screw rod fixedly connected to it to rotate, and under the combined action of the threaded connection between the second screw rod and the first movable plate, and the sliding connection between the first movable plate and the limiting rod, the position of the first movable plate changes.

[0011] Furthermore, the first electric push rod is fixedly connected to the baffle, and the width of the baffle is smaller than the distance between two adjacent conveying rollers.

[0012] By adopting the above technical solution, when the first electric push rod is started, the position of the baffle fixed at its output end can be changed in the vertical direction, so that it can be extended or retracted between two adjacent conveying rollers.

[0013] Furthermore, the optical sensors are provided in two groups, the two groups of optical sensors are symmetrically arranged, and each group of optical sensors is provided with a plurality of optical sensors.

[0014] By adopting the above technical solution, two groups of symmetrically arranged light sensors can monitor the light changes on both sides at the same time to ensure the accuracy of the monitoring results.

[0015] Furthermore, the first movable plate is fixedly connected to the second movable plate, the second movable plate is slidably connected to the conveying frame body, and the second electric push rod is fixedly connected to the second movable plate.

[0016] By adopting the above technical solution, when the first movable plate moves, it drives the second movable plate fixedly connected thereto to slide along the side of the conveyor frame body, and adjusts the position accordingly, thereby effectively adjusting the position of the second electric push rod.

[0017] Furthermore, a push plate is provided at the output end of the second electric push rod, and a buffer plate is provided at one side of the conveying frame body.

[0018] By adopting the above technical solution and setting the push plate, it is convenient to push the intercepted oversized logistics pieces off the conveyor frame body, thereby completing the sorting of the oversized logistics pieces.

[0019] Furthermore, the second electric push rod is fixedly connected to the push plate, and a rubber pad is provided on a side of the push plate away from the second electric push rod.

[0020] By adopting the above technical solution, when the second electric push rod is started, the push plate fixed at its output end will move to push the logistics parts on one side of the push plate down.

[0021] Furthermore, the buffer plate is in the form of a downwardly inclined arc-shaped plate, and guard plates are provided on both sides of the buffer plate.

[0022] By adopting the above technical solution, the structural setting of the buffer plate can not only play a good buffering role, but also ensure the smooth sliding of the logistics parts.

[0023] Furthermore, the sorting camera, the conveying roller, the first motor, the control button, the second motor, the first electric push rod, the light sensor and the second electric push rod are all connected to an external controller.

[0024] By adopting the above technical solution, the operation process of all electrical components is controlled by an external controller, so that the start and stop of the operation of each electrical component is more accurate.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model sets a first movable plate, a baffle and a light sensor. The external controller uses the light change signal received by the light sensor to control the position of the first movable plate through the second motor, thereby ensuring that the baffle intercepts the oversized logistics pieces on the other side away from the interception plate, blocking the advancement of subsequent logistics pieces until the pushing mechanism pushes the oversized logistics pieces off the buffer plate and the baffle is retracted by the first electric push rod. The intercepted logistics pieces continue to move forward with the transmission of the conveying roller, and the baffle is released from the interception of the subsequent logistics pieces. There is no imbalance in the interception resistance, so it can be ensured that when sorting oversized logistics pieces, the positions of the subsequent logistics pieces will not be offset.

[0027] 2. The utility model provides a buffer plate and a guard plate. The buffer plate can be used to cushion the impact caused by the high vertical height of the oversized logistics items when they fall, which can not only ensure that the oversized logistics items fall smoothly, but also prevent the oversized logistics items from being damaged during the falling process. The setting of the guard plate can effectively protect the oversized logistics items during the falling process and prevent them from falling from both sides of the buffer plate.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0034] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0035] A logistics line conveyor rack, such as Figure 1-Figure 4 As shown, it includes a conveyor frame body 1, a sorting mechanism 2, a sorting camera 3, a conveying roller 4, an intercepting mechanism 5 and a pushing mechanism 7, the intercepting mechanism 5 includes a U-shaped frame 51, a first motor 52 is arranged on the top of the U-shaped frame 51, a first screw 53 is arranged at the output end of the first motor 52, an intercepting plate 54 is arranged on the first screw 53, and a control button 55 is arranged on the front side of the intercepting plate 54, the pushing mechanism 7 includes a second movable plate 71 and a second electric push rod 72, and a conveying intercepting mechanism 6 is arranged at the bottom of the conveyor frame body 1; the conveying intercepting mechanism 6 includes a fixed seat 61 and a first movable plate 65, a second motor 62 is arranged on one side of the fixed seat 61, a second screw 63 is arranged at the output end of the second motor 62, and limiting rods 64 are arranged on both sides of the second screw 63, a first electric push rod 66 is arranged on the top of the first movable plate 65, and a baffle 66 is arranged at the output end of the first electric push rod 66. 7. Optical sensors 68 are arranged on both sides of the baffle 67. The transmission interception mechanism 6 is arranged so that after the oversized logistics pieces are successfully intercepted by the interception plate 54 and before the subsequent logistics pieces move to this place, the baffle 67 can be extended between the two adjacent conveying rollers 4 on the rear side of the moving direction of the oversized logistics pieces, so that before the oversized logistics pieces are pushed down the conveyor frame body 1 by the second electric push rod 72 and the push plate 73, the subsequent logistics pieces can be prevented from being displaced by the conveying rollers 4, and the occurrence of uneven interception resistance can be eliminated, so as to ensure that the subsequent normal logistics pieces will not be offset due to the sorting process of the oversized logistics pieces. The optical sensor 68 is used to monitor the position where the light changes significantly, so as to control the power on and off of the second motor 62 through an external controller, adjust the position of the first movable plate 65, and further ensure that the baffle 67 is smoothly extended from between the two adjacent conveying rollers 4 on the rear side of the moving direction of the oversized logistics pieces.

[0036] See also Figure 1 , Figure 2 , Figure 3The first screw 53 is fixedly connected to the first motor 52, the interception plate 54 is threadedly connected to the first screw 53, and the interception plate 54 is slidably connected to the U-shaped frame 51. When the first motor 52 is started, it drives the first screw 53 fixedly connected thereto to rotate. Under the threaded connection between the interception plate 54 and the first screw 53, and the sliding connection between the interception plate 54 and the U-shaped frame 51, the interception plate 54 moves up and down and adjusts its position so that the interception plate 54 can smoothly intercept the set oversized logistics parts according to the height at which the sorting camera 3 takes effect.

[0037] See also Figure 1 , Figure 2 , Figure 3 The second motor 62 is fixedly connected to the second screw 63, the second screw 63 is threadedly connected to the first movable plate 65, and the first movable plate 65 is slidably connected to the limiting rod 64. When the second motor 62 is started, it drives the second screw 63 fixedly connected thereto to rotate, and under the joint action of the threaded connection between the second screw 63 and the first movable plate 65 and the sliding connection between the first movable plate 65 and the limiting rod 64, the position of the first movable plate 65 changes, thereby changing the positions of the baffle 67 and the light sensor 68, so that the light sensor 68 can monitor the light changes in real time during the displacement process, and determine the position of the baffle 67 through the controller.

[0038] See also Figure 1 , Figure 3 , Figure 4 The first electric push rod 66 is fixedly connected to the baffle 67, and the width of the baffle 67 is smaller than the spacing between two adjacent conveying rollers 4. When the first electric push rod 66 is started, the position of the baffle 67 fixed at its output end can be changed in the vertical direction, so that it can be extended or retracted between two adjacent conveying rollers 4, and then when sorting oversized logistics pieces, the subsequent moving normal logistics pieces can be intercepted to avoid the process of sorting oversized logistics pieces affecting the moving normal logistics pieces.

[0039] See also Figure 1 There are two groups of light sensors 68, which are symmetrically arranged. Each group of light sensors 68 is provided with multiple light sensors. The two symmetrically arranged groups of light sensors 68 can monitor the light changes on both sides at the same time to ensure the accuracy of the monitoring results. Because the width of oversized logistics items may vary, multiple light sensors 68 can be set to function normally for oversized logistics items of different widths.

[0040] See also Figure 1 , Figure 2 , Figure 3The first movable plate 65 is fixedly connected to the second movable plate 71, the second movable plate 71 is slidably connected to the conveyor frame body 1, and the second electric push rod 72 is fixedly connected to the second movable plate 71. When the first movable plate 65 moves, it drives the second movable plate 71 fixedly connected thereto to slide along the side of the conveyor frame body 1 and adjust the position accordingly, thereby effectively adjusting the position of the second electric push rod 72, and indirectly realizing the adjustment of the position of the push plate 73, ensuring that the push plate 73 is in a position that is more suitable for applying force to push oversized logistics parts. Embodiment 2:

[0041] See also Figure 1 , Figure 2 , Figure 3 A push plate 73 is provided at the output end of the second electric push rod 72, and a buffer plate 8 is provided on one side of the conveyor frame body 1. The setting of the push plate 73 facilitates the pushing of the intercepted oversized logistics pieces from the conveyor frame body 1 to complete the sorting of the oversized logistics pieces. The buffer plate 8 can play a buffering role in the process of the oversized logistics pieces falling from the conveyor frame body 1, thereby reducing the impact of the falling process on the oversized logistics pieces.

[0042] See also Figure 1 , Figure 2 , Figure 3 The second electric push rod 72 is fixedly connected to the push plate 73. A rubber pad is provided on the side of the push plate 73 away from the second electric push rod 72. When the second electric push rod 72 is started, the push plate 73 fixed at its output end will move to push down the logistics parts on one side of the push plate 73. The setting of the rubber pad ensures that when the push plate 73 pushes the logistics parts, it will not cause damage to the outer surface of the logistics parts.

[0043] See also Figure 2 The buffer plate 8 is a downwardly inclined arc-shaped plate structure, and guard plates 9 are arranged on both sides of the buffer plate 8. The structural setting of the buffer plate 8 can not only play a good buffering role, but also ensure the smooth sliding of the logistics pieces. The setting of the guard plates 9 can effectively protect the oversized logistics pieces during the falling process and prevent them from falling from the two sides of the buffer plate 8.

[0044] See also Figure 1 , Figure 2 , Figure 3 The sorting camera 3, the conveying roller 4, the first motor 52, the control button 55, the second motor 62, the first electric push rod 66, the light sensor 68 and the second electric push rod 72 are all connected to the external controller. The external controller is used to control the operation process of all electrical components, so that the start and stop of the operation of each electrical component is more accurate. At the same time, when the external controller controls the signal transmission and the communication of instructions, the response time of each electrical component is shorter.

[0045] The implementation principle of the utility model is as follows: first, the first motor 52 is controlled by an external controller to start, and under the joint action of the first screw 53 and the U-shaped frame 51, the interception plate 54 is adjusted to a suitable height to limit the height of the logistics piece. When the size of the logistics piece exceeds the set height, the logistics piece will be successfully intercepted by the interception plate 54, and the control button 55 in the middle of the interception plate 54 is activated through the contact between the logistics piece and the interception plate 54; secondly, the external controller controls the second motor 62 to start at the same time, and with the assistance of the second screw 63 and the limiting rods on both sides thereof, the first moving plate 65 moves. During the movement, the optical sensor 68 monitors the light change in real time. When there is no logistics piece blocking the conveying roller 4, the optical sensor 68 will monitor the light change at fixed intervals. When it is located at the bottom of the conveying roller 4, the light becomes dark, and when it is located between the conveying rollers 4, the light becomes bright. When there is a logistics piece blocking the conveying roller 4, the space between the conveying rollers 4 is also dark. When the light detects the change again, the baffle 67 and the optical sensors 68 on both sides thereof move to the tail of the intercepted logistics piece. At the end, when the position where the light changes significantly is detected, the signal is transmitted to the external controller in time, the second motor 62 is controlled to stop starting, and the first movable plate 65 is fixed at the position where the light starts to change; thereafter, the first electric push rod 66 is started under the action of the controller, and the baffle 67 is pushed out between the conveying rollers 4 to intercept the next logistics piece before it moves there; while the first movable plate 65 moves, it will drive the second movable plate 71 fixedly connected thereto to adjust its position, ensuring that the push plate 73 plays a role between the baffle 67 and the interception plate 54, at this time, the second electric push rod 72 is started, and the intercepted logistics piece is pushed down from the conveying rack body 1 through the buffer plate 8 by the push plate 73, and then the second electric push rod 72 retracts the push plate 73; finally, the control button 55 is released, and the controller controls the first electric push rod 66 to pull the baffle 67 downward to reset, and the baffle 67 no longer blocks the movement of subsequent logistics pieces, and the logistics pieces that meet the specification requirements are smoothly conveyed to the bottom of the sorting camera 3 through the conveying roller 4 for face sheet reading, and then continue to move to the sorting mechanism 2 to achieve final sorting.

[0046] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.
