Description

Technical Field

[0001] This utility model relates to the field of logistics, specifically to a goods conveying mechanism in logistics equipment. Background Technology

[0002] Logistics conveying mechanisms use conveyor belts, on which items are placed and moved forward. Because conveyor belts travel long distances, and the drive rollers inevitably have shape and position errors, items moving along the conveyor belt may deviate from its conveying direction, causing them to detach from the belt. Even with side guards, items may still get stuck at the edge of the conveyor belt, or even accumulate in large numbers at the edge. Utility Model Content

[0003] The technical problem solved by this utility model is that items displaced along the logistics conveyor belt deviate from the conveyor belt's conveying direction, causing the items to leave the conveyor belt, or to remain or accumulate at the edge of the conveyor belt.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a logistics conveying mechanism, including a pair of frames, conveyor rollers mounted on the pair of frames, and a conveyor belt wound on the conveyor rollers. A correction device is installed on the frame. The correction device includes a base fixedly mounted on the frame and a rod mounted on the base. The rod is inclined in the direction of the conveyor belt's conveying direction and extends above the conveyor belt. The rod includes a front rod and a rear rod. The tail of the front rod is hinged to the front end of the rear rod. The tail of the rear rod is mounted on the base. An elastic device is provided in the rear rod. The elastic device is connected to a cable, and the cable is connected to the tail end of the front rod.

[0005] According to the above technical solution, if an item moving on the conveyor belt deviates from the conveying direction and moves to the edge of the conveyor belt, the entanglement device distributed along the conveying direction of the conveyor belt can guide the item to the middle position of the conveyor belt. Specifically, when the item comes into contact with the inclined rod, it will move forward and towards the middle position of the conveyor belt under the conveyor belt's transport.

[0006] The presence of a correction device may obstruct multiple items, causing them to become stuck at the rod. If this occurs, the more items stuck, the greater the force on the front rod. The items overcome the tension of the elastic device on the front rod, causing it to rotate relative to the rear rod, releasing the stuck items. This effectively avoids item sticking caused by the presence of an entanglement device. After the items leave the front rod, the elastic device returns the front rod to its original position.

[0007] The front section of the rod has a flat connecting part at its tail end and a snap-fit ​​part at its front end. The flat connecting part snaps into the snap-fit ​​part's groove and is connected to the snap-fit ​​part via a first hinge shaft, thus achieving the hinge connection between the front and rear sections of the rod.

[0008] The tail end of the flat connector is provided with a cable connecting lug. The hollow cavity of the rear rod is connected to the slot of the snap-fit ​​part through a perforation. The front end of the cable is connected to the cable connecting lug, and the rear end of the cable passes through the perforation and is connected to the elastic device in the hollow cavity of the rear rod.

[0009] The elastic device includes a cable rod connected to a cable, a piston fixed to the cable rod, and a spring abutting against the piston. The piston and spring are housed within the elastic device housing. The cable rod protrudes outward from the housing, and one end of the cable rod has a cable hole for connecting the cable. When the object exerts a sufficiently large force on the front section of the rod, it causes the front section to rotate relative to the rear section. The cable pulls the cable rod, displacing the piston within the elastic device housing and compressing the spring. After the object detaches from the front section, the front section returns to its original position under the action of the spring.

[0010] A lever is fixed to the housing of the elastic device. A slot is formed on the side wall of the rear section of the lever, and the lever fits into the slot. A fastening nut is screwed onto the lever. The worker can loosen the fastening nut to adjust the position of the elastic device within the rear section of the lever, thereby adjusting the load-bearing capacity of the front section of the lever. After the position is adjusted, the worker tightens the fastening nut to fix the position of the elastic device.

[0011] The base has a second hinge shaft that mates with the rear section of the rod. The base also has several indexing holes centered on the second hinge shaft. The rear section of the rod has a pin hole at its tail. When the rear section of the rod rotates around the second hinge shaft, the pin can be inserted into the vertically aligned pin hole and the indexing hole. The worker pulls out the pin, rotates the rod around the second hinge shaft to adjust its tilt above the conveyor belt, and then inserts the pin into the corresponding pin hole and indexing hole to position the rod.

[0012] The rod of this invention can correct the deviation of items on the conveyor belt and can automatically bend like a joint to let the stuck items pass, so that the conveyor belt can transport items smoothly. Attached Figure Description

[0026] Combination Figure 1 , Figure 2 , Figure 4 A logistics conveying mechanism includes a pair of frames 10, conveyor rollers mounted on the frames, and a conveyor belt 20 wound around the conveyor rollers. A correction device 30 is mounted on the frames. The correction device includes a base 40 fixedly mounted on the frames and a rod 50 mounted on the base. The rod is inclined in the direction of the conveyor belt's movement and extends above the conveyor belt. The rod includes a front rod 51 and a rear rod 52. The tail of the front rod is hinged to the front end of the rear rod. The tail of the rear rod is mounted on the base. An elastic device 60 is provided in the rear rod, connected to a cable 53, which is connected to the tail end of the front rod.

[0027] The front section member 51 has a flat connecting part 511 at its tail end and a snap-fit ​​part 521 at its front end. The flat connecting part snaps into the snap-fit ​​part's slot and is connected to the snap-fit ​​part via a first hinge shaft 54.

[0028] The tail end of the flat connecting part 511 is provided with a cable connecting ear 512. The hollow cavity of the rear rod 52 is connected to the slot of the snap-fit ​​part 521 through the through hole 522. The front end of the cable 53 is connected to the cable connecting ear, and the rear end of the cable passes through the through hole and is connected to the elastic device 60 in the hollow cavity of the rear rod.

[0029] like Figure 4 The elastic device 60 includes a cable rod 61 connected to the cable 53, a piston 62 fixed on the cable rod, and a spring 63 abutting against the piston. The piston and spring are fitted in the elastic device housing 64. The cable rod protrudes outward from the elastic device housing. One end of the cable rod is provided with a cable hole 610 for connecting the cable.

[0030] like Figure 5 A lever 65 is fixed on the housing 64 of the elastic device. A strip groove 523 is opened on the side wall of the rear rod 52. The lever fits in the strip groove and a fastening nut 66 is screwed onto the lever.

[0031] like Figure 4 The base 40 is provided with a second hinge shaft 41 that cooperates with the rear rod 52. The base is provided with a number of indexing holes 42, which are distributed around the second hinge shaft. The tail of the rear rod is provided with a pin hole 43. When the rear rod rotates around the second hinge shaft, the pin can be inserted into the vertically aligned pin hole and the indexing hole.

[0032] If an item moving on the conveyor belt 20 deviates from the conveying direction and moves to the edge of the conveyor belt, the entanglement device 30, distributed along the conveying direction, can guide the item to the middle position of the conveyor belt 20. Specifically, when an item comes into contact with the inclined rod 50, it will move forward and towards the middle position of the conveyor belt under the conveyor belt 20. The presence of the correction device 30 may block multiple items, causing items to become stuck at the rod 50. If this happens, the more items stuck, the greater the force on the front rod 51. The items overcome the tension of the elastic device on the front rod, causing the front rod to rotate relative to the rear rod 52, releasing the stuck items. In this way, the item stuck due to the presence of the entanglement device can be effectively avoided. After the item leaves the front rod 51, the front rod returns to its original position under the tension of the elastic device 60.

For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
