Description

Technical Field

[0001] This utility model relates to the field of gravity slide technology, specifically a gravity slide with a pneumatic limiting device. Background Technology

[0002] Gravity slides are devices that use the principle of gravity to transport workpieces or pallets. With their tilted structure, they use the gravity of the parts to achieve automatic downward transport and are widely used in automated production lines, warehousing and logistics. However, existing gravity slides lack effective orderly limiting mechanisms, and parts are prone to continuous stacking and collisions during the downward movement. Especially when manually or by a robotic arm, parts may interfere with each other, which may not only damage the surface of the parts but also pose a safety hazard to the personnel handling the parts. Utility Model Content

[0003] The main technical problem to be solved by this utility model is to provide a gravity slide with a pneumatic limiting device. This slide can be adapted to gravity conveying scenarios of various plate-type parts, realize the orderly conveying of plate-type parts, avoid collision between front and rear plates when picking up parts, protect the surface quality of the plates, and improve the safety when picking up parts.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A gravity slide with a pneumatic limiting device includes a gravity slide body and a safety baffle located on one side of the gravity slide body. The gravity slide body is arranged in two rows and fixed to the ground by multiple support assemblies. Two rows of slide rails are provided on the upper end of the gravity slide body. A first limiting assembly, a second limiting assembly, and a buffer assembly are arranged between the two rows of slide rails. The buffer assembly is located on the side of the gravity slide body closer to the safety baffle. The first limiting assembly is located on the side of the gravity slide body away from the safety baffle. The second limiting assembly is located between the first limiting assembly and the buffer assembly.

[0005] The following are further optimizations of the above technical solution by this utility model: Both the first limiting component and the second limiting component include a cylinder. The piston rod of the cylinder is connected to a pressure arm. Both ends of the pressure arm are provided with buffer blocks. The pressure arm and the buffer blocks are connected by a gasket.

[0006] Further optimization: The support assembly includes a base and a square tube.

[0007] Further optimization: A first photoelectric switch, a second photoelectric switch, a third photoelectric switch, and a fourth photoelectric switch are respectively installed on both sides of the two columns of slide rails.

[0008] Further optimization: The first photoelectric switch and the third photoelectric switch are correspondingly arranged on both sides of the first limiting component, and the second photoelectric switch and the fourth photoelectric switch are correspondingly arranged on both sides of the second limiting component.

[0009] Further optimization: A fifth photoelectric switch and a sixth photoelectric switch are provided on both sides of the buffer component.

[0010] This utility model adopts the above-mentioned technical solution, with ingenious conception and reasonable structure. It uses the linkage control of limit components and photoelectric switches to achieve orderly conveying of "the next plate slides down only after the previous plate is taken away", avoiding collision between plates before and after picking up the parts, protecting the surface quality of the plates, and improving the safety of picking up the parts. At the same time, the buffer block and buffer component can further prevent damage to the plates.

[0014] like Figure 1-4 As shown: A gravity slide with a pneumatic limiting device includes a gravity slide body 1 and a safety baffle 2 located on one side of the gravity slide body 1. The gravity slide body 1 is arranged in two rows and fixed to the ground by multiple support leg assemblies 3. Two rows of slide rails 5 are provided on the upper end of the gravity slide body 1. A first limiting assembly 6, a second limiting assembly 8 and a buffer assembly 4 are arranged between the two rows of slide rails 5. The buffer assembly 4 is located on the side of the gravity slide body 1 closer to the safety baffle 2. The first limiting assembly 6 is located on the side of the gravity slide body 1 away from the safety baffle 2. The second limiting assembly 8 is located between the first limiting assembly 6 and the buffer assembly 4.

[0015] In this embodiment, the robotic arm places the plate to be transported at the end of the slide rail 5 away from the buffer assembly 4. Under the action of gravity, the plate is transported from one end of the slide rail 5 to the other end. When the plate is transported to the position of the buffer assembly 4, the buffer assembly 4 buffers the plate to stop the transport and wait for the next process.

[0016] When the buffer assembly 4 fails to buffer and stop the plate, the safety baffle 2 is used to block the plate that is rushing out of the gravity slide body 1, so as to prevent the plate from rushing out of the gravity slide body 1 without obstruction under the action of inertia, thereby endangering the surrounding workers and personnel and equipment in adjacent processes.

[0017] The first limiting component 6 and the second limiting component 8 both include a cylinder 61. The piston rod of the cylinder 61 is connected to a pressure arm 62. Both ends of the pressure arm 62 are provided with buffer blocks 63. The pressure arm 62 and the buffer blocks 63 are connected by a gasket 64.

[0018] In this embodiment, the pad 64 is used to adjust the position of the buffer block 63.

[0019] In the initial position, both the first limiting component 6 and the second limiting component 8 are in the clamping state, that is, the piston rod of the cylinder 61 is in the extended state, the pressure arm 62 rotates to the top, and the buffer block 63 is located at the top under the action of the pressure arm 62. The buffer block 63 can limit the plate. When cylinder 61 is in the retracted state, pressure arm 62 rotates downwards, and buffer block 63 retracts to below cylinder 61 under the action of pressure arm 62, releasing the plate from its limiting position, allowing the plate to continue to be transported under the action of gravity, which is convenient for use.

[0020] The support assembly 3 includes a base 31 and a square tube 32. The base 31 is fixed on the ground to prevent the gravity slide body 1 from shaking.

[0021] The two slide rails 5 are respectively equipped with a first photoelectric switch 71, a second photoelectric switch 72, a third photoelectric switch 73, and a fourth photoelectric switch 74 on both sides.

[0022] The first photoelectric switch 71 and the third photoelectric switch 73 are correspondingly disposed on both sides of the first limiting component 6, and the second photoelectric switch 72 and the fourth photoelectric switch 74 are correspondingly disposed on both sides of the second limiting component 8.

[0023] The buffer assembly 4 is provided with a fifth photoelectric switch 75 and a sixth photoelectric switch 76 on both sides.

[0024] In this embodiment, when the plate is placed on the slide rail 5 of the gravity slide body 1 by the robot arm, the first limiting component 6 is in a clamped state, that is, the buffer block 63 on the first limiting component 6 can limit the plate. At this time, the plate blocks the first photoelectric switch 71 and the third photoelectric switch 73, so that the first photoelectric switch 71 and the third photoelectric switch 73 send signals to the control module, so that the robot arm releases the plate and leaves.

[0025] When the first photoelectric switch 71 and the third photoelectric switch 73 have sensing signals and the second photoelectric switch 72 and the fourth photoelectric switch 74 have no signals, the control module controls the piston rod of the cylinder 61 of the first limit component 6 to retract, and the buffer block 63 of the first limit component 6 rotates to the lower position. At this time, the plate will not be restricted and will be transported along the slide rail 5 under the action of gravity.

[0026] When the plate is conveyed to the position of the second limiting component 8, the second limiting component 8 restricts the plate. At this time, the plate blocks the second photoelectric switch 72 and the fourth photoelectric switch 74. The control module detects that the second photoelectric switch 72 and the fourth photoelectric switch 74 have sensing signals, while the fifth photoelectric switch 75 and the sixth photoelectric switch 76 have no sensing signals. At this time, the control module controls the piston rod of the cylinder 61 of the second limiting component 8 to retract and controls the piston rod of the cylinder 61 of the first limiting component 6 to extend. The buffer block 63 of the second limiting component 8 rotates downward. At this time, the plate is no longer restricted and continues to be conveyed along the slide rail 5 under the action of gravity. At the same time, the first limiting component 6 returns to the clamping state.

[0027] When the board is conveyed to the position of the buffer assembly 4, the fifth photoelectric switch 75 and the sixth photoelectric switch 76 have sensing signals. The control assembly controls the piston rod of the cylinder 61 of the second limit assembly 8 to output, so that the second limit assembly 8 returns to the clamping state. At the same time, the control assembly controls the mechanical gripper to grab the board. After the board is grabbed and taken away, all six photoelectric switches have no sensing signals. The control assembly then places a new board for transportation, which is convenient for use.

[0028] For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of this utility model, based on the teachings of this utility model, still fall within the protection scope of this utility model.
