Description

Technical Field

[0001] The present invention relates to a power - free parking device used at a goods transfer position, belonging to the technical field of automated logistics. Background Art

[0002] In the rapidly developing automated logistics industry, the storage area (including single - machine access mechanisms with internal tracks) and conveyor lines are essential components. To stop the goods on the conveyor line at a designated position, a parking mechanism or a stopping mechanism must be used. The Chinese invention patent with the patent number CN201811282547.X discloses a safe logistics system applied to fireworks production, which can automatically transfer fireworks products between different workstations, ensure the consistency and safety of loading and unloading, and improve production efficiency; the Chinese utility model patent with the patent number CN202321124167.X discloses a simple side detection device for a logistics line, which can stop the pallet during conveying operation under the action of a stopper.

[0003] However, the inventors of this invention have found the following problems in the prior art: The parking devices on the market often adopt the following methods: PLC controls the lifting of the cylinder; PLC controls the lifting of the motor; using servo to control the speed and start - stop of the roller. These all require their own power sources and control systems, with complex structures. Later, the power sources need to be maintained, consuming high labor and material costs. Therefore, further improvement can be made. Summary of the Invention

[0004] To solve the above - mentioned technical problems, the present invention provides a power - free parking device used at a goods transfer position, which can solve the technical problems of the existing stopping devices that require power sources and control systems, have complex structures, high costs, and consume a lot of labor and materials for maintenance.

[0007] The rotating component further includes a pedestal bearing, a screw, a length - adjustable screw, and a mounting frame; both side surfaces of the mounting frame are fixedly connected to the pedestal bearing, and the pedestal bearing is sleeved on the support shaft; the front surface of the mounting frame is symmetrically fixed with counterweight blocks through the screw, and the mass on the side of the counterweight block on the mounting frame is always greater than that on the non - counterweight side.

[0008] The surface area of the mounting bracket away from the counterweight is provided with an array of weight-reducing holes.

[0009] The surface of the mounting bracket is threadedly connected with an array of length-adjustable screws.

[0010] The mass of the counterweight is 2 - 4 kilograms greater than the mass of the lifting baffle.

Detailed implementation mode

[0023] The technical solution of the present invention will be further described below, but the scope of protection claimed is not limited thereto.

[0024] The first embodiment of the present invention relates to a Figures 1-5 kind of power-free parking device used at the goods transfer position as shown, including a lifting baffle 7, a fixing component 11 and a rotating component 12; the rotating component 12 is rotatably connected to the middle of the fixing component 11 through a bearing; the end of the rotating component 12 is fixedly connected to the lifting baffle 7; the rotating component 12 is counterweighted by the counterweight block 2 to make the lifting baffle 7 in a lifted state; the fixing component 11 includes a connecting block 1 to fix the entire parking device; the lifting baffle 7 is used to block and stop the goods 15 to achieve precise positioning; the fixing component 11 plays a role of fixing and supporting; the rotating component 12 is used to realize the switching of the blocking and stopping function; the connecting block 1 fixes the device in the process; the pedestal bearing 4 makes the rotating component 12 rotate smoothly; the counterweight block 2 is mainly used for increasing weight; the connecting block 1 is used to fix the entire device.

[0025] The second embodiment of the present invention is basically the same as the first embodiment, mainly in the scheme optimization of the rotating component. The rotating component 12 further includes a pedestal bearing 4, a screw 5, a length-adjustable screw 6 and a mounting bracket 10; both side surfaces of the mounting bracket 10 are fixedly connected to the pedestal bearing 4, and the pedestal bearing 4 is sleeved on the support shaft 8; the front surface of the mounting bracket 10 is symmetrically and fixedly connected with the counterweight block 2 through the screw 5, and the mass on the side of the counterweight block 2 on the mounting bracket 10 is always greater than that on the non-counterweight side; the pedestal bearing 4 makes the rotating component 12 rotate smoothly; the screw 5 is used to fix the counterweight block 2 on the surface of the mounting bracket 10.

[0026] The area of the mounting bracket 10 far from the surface of the counterweight block 2 is provided with an array of weight reduction holes 16, which can reduce the mass on this side and assist the center of gravity of the mounting bracket 10 to tend to shift to the other side, realizing the deflection of the mounting bracket 10.

[0027] The surface of the mounting bracket 10 is threadedly connected with an array of length-adjustable screws 6, and the length can be adjusted according to the actual application scenario, and then the lifting height of the lifting baffle 7 can be adjusted.

[0028] The mass of the counterweight block 2 is 2 - 4 kilograms larger than the mass of the lifting baffle 7. The counterweight block 2 can increase the mass on one side of the mounting bracket 10, and then lift the lifting baffle 7 to realize the blocking and stopping function.

[0029] The fixed part 11 further includes a fixed shaft 3 and a support shaft 8. Symmetrically threaded connection blocks 1 are provided at both ends of the support shaft 8. The end faces of the connection blocks 1 are fixed on the surface of the transmission line 13, and the connection blocks 1 are shaped like a "Ji" character, which can facilitate the tightening of the support shaft 8 and avoid inconvenient installation.

[0030] The fixed shaft 3 is arranged parallel to the support shaft 8, and both ends of the fixed shaft 3 are fixedly connected to the surface of the connection block 1; the fixed shaft 3 is used to limit the rotation angle of the rotating part 12; the support shaft 8 supports the rotating part 12.

[0031] Shaft collars 9 are symmetrically sleeved on the shaft rods at both ends of the support shaft 8, and the shaft collars 9 can position the axial position of the rotating part 12.

[0032] The projection shape of the lifting baffle 7 in the axial direction of the length-adjustable screw 6 is trapezoidal, and the lifting baffle 7 is provided with an array of through holes. The through holes are mainly to reduce the mass and cooperate with the counterweight 2 to enable itself to be lifted; both side ends of the lifting baffle 7 have inwardly curved surfaces, so that the longitudinal goods 15 can be smoothly transferred from the access mechanism 14 to the conveyor line.

[0033] The height range of the lifting baffle 7 lifted relative to the fixed shaft 3 is 30 - 40 cm. According to the lever principle, the longer the length of the length-adjustable screw 6 extends, the higher the height of the lifting baffle 7 is lifted; the lifting baffle 7 is always in the lifted state relative to the counterweight 2 except when pressed by the goods, that is, in the blocking state, and can block and position the goods 15.

[0034] Based on this, a typical working process of the present invention is as follows:

[0035] When the present invention is implemented, as Figures 1-5 shown, the connection block 1 is fixed on the inner surface of the conveyor line, the counterweight 2 is fixed, and the length of the length-adjustable screw 6 is adjusted according to the working conditions. At this time, the lifting baffle 7 is in the lifted state; when the goods 15 on the conveyor line enter the storage area through the access mechanism 14, the lifted lifting baffle 7 blocks the goods 15, and the access mechanism 14 extends the forklift to lift the goods 15 to the storage area; when the goods 15 in the storage area are shipped out, the access mechanism 14 extends the forklift to place the goods 15 on the conveyor line, and the goods 15 press on the lifting baffle 7, so that the upper end surface of the lifting baffle 7 is flush with the conveyor line roller. In this state, the goods 15 can be conveyed on the conveyor line.
