Abstract
Description
Technical Field
[0001] This utility model relates to the field of stacking and handling machine technology, specifically a stacking and handling machine. Background Technology
[0002] Stacking conveyors are automated mechanical equipment used to separate, transport, and re-stack stacked items. They are widely used in brick factories, aerated concrete block factories, and board processing plants, and can effectively improve material handling and stacking efficiency while reducing manual labor intensity.
[0003] One of the mainstream gripping methods is vacuum suction cup adsorption gripping. Vacuum suction cup adsorption gripping mainly relies on the negative pressure formed between the suction cup and the material surface to achieve fixation. Although it performs well when gripping materials with flat surfaces and dense materials, it is very easy to have air leakage when dealing with materials with rough surfaces, holes or gaps, which leads to unstable negative pressure and the risk of material falling off. Therefore, a stacking and handling machine is needed. Summary of the Invention
[0004] The purpose of this invention is to provide a stacking and handling machine that solves the problems mentioned in the background art.
[0005] This application provides a stacking conveyor, including a mounting frame. Grooves are formed on both outer walls of the mounting frame. An adjusting plate is rotatably connected to the interior of each groove via a rotating shaft. A motor is fixedly connected to the front wall of the mounting frame. The output shaft of the motor passes through the mounting frame and is fixedly connected to the adjusting plate. A second electric push rod is installed inside the adjusting plate. The piston rod of the second electric push rod passes through the exterior of the adjusting plate and is fixedly connected to a support plate. A vacuum pump is fixedly connected to the top of the mounting frame. Three vacuum suction cups are fixedly connected to the bottom of the mounting frame. A main air pipe is fixedly connected to the vacuum pump's vacuuming end. The main air pipe passes through the interior of the mounting frame and is fixedly connected to three branch pipes, each of which is fixedly connected to one of the three vacuum suction cups.
[0006] In operation, first start the motor. The motor's output shaft drives the lead screw to rotate, converting the slider's rotational motion into linear motion. This allows the mounting frame to reciprocate, adjusting its position. After moving the mounting frame above the goods being transported, the piston rod of the first electric push rod pushes the mounting frame downwards until the vacuum suction cup at the bottom of the mounting frame contacts the goods. At this point, the adjusting plate is extended to both sides of the mounting frame to avoid affecting the contact between the vacuum suction cup and the goods. Start the vacuum pump, which distributes air through the main pipe to three branch pipes. Use the vacuum suction cup to create a vacuum on the top surface of the goods, pre-fixing them from the top. After the goods are lifted, the motor... The output shaft of the device can drive the adjustment plates to flip, so that the two adjustment plates are located at the bottom of both sides of the mounting frame. The adjustment plates can limit the goods adsorbed by the vacuum suction cup. Then, the second electric push rod inside the adjustment plate pushes the pallet to rise, so that the pallet supports the goods from the bottom. The combination of vacuum suction cup pre-fixation and mechanical pallet bottom support solves the safety hazards of vacuum suction cup leakage on the surface of goods or power failure, and prevents goods from falling off. After the goods reach the designated position, the motor first flips the adjustment plates to the sides to reset the adjustment plates. Then, the first electric push rod lowers the material and places it on the designated pallet or stacking area. The vacuum suction cup is then deflated, completing one stacking and handling operation.
[0007] Optionally, a horizontal plate is fixedly connected to one side of the outer wall of the column, and a motor is fixedly connected to the side of the horizontal plate away from the column. The output shaft of the motor passes through the interior of the horizontal plate and is fixedly connected to a lead screw through a coupling. A slider is threaded on the lead screw, and a first electric push rod is fixedly connected to the bottom end of the slider. The end face of the piston rod of the first electric push rod is fixedly connected to the top end of the mounting bracket.
[0008] By adopting the above technical solution, the output shaft of the motor can drive the lead screw to rotate, and the lead screw can convert the rotational motion of the slider into linear motion, thereby driving the mounting frame to reciprocate.
[0009] Optionally, a base is fixedly connected to the bottom end of the column.
[0010] By adopting the above technical solution, the column can be more stably fixed to the ground.
[0011] Optionally, the bottom end of the horizontal plate is provided with a groove along the length direction that is adapted to the slider.
[0012] By adopting the above technical solution, it is beneficial for the slider to slide smoothly.
[0013] Optionally, both the tray and the adjusting plate are made of stainless steel.
[0014] By adopting the above technical solutions, the corrosion resistance of the pallet and the adjusting plate can be improved, and their service life can be extended.
[0015] Optionally, a solenoid valve may be installed on the branch pipe.
[0016] By adopting the above technical solution, if a branch pipe or its connected vacuum suction cup malfunctions, the faulty area can be isolated from the main vacuum system by closing the solenoid valve of that branch pipe, ensuring that the other two sets of vacuum suction cups can still work normally and maintain part of the equipment's operational capacity.
[0017] Optionally, the width between the two adjusting plates is adapted to the width of the goods being transported.
[0018] By adopting the above technical solution, the adjusting plate can be clamped on both outer walls of the transported goods, which can limit the movement of the goods and improve the stability during transport.
[0019] Optionally, there are two first electric push rods, which are symmetrically arranged on the left and right, and the piston rods of the two first electric push rods extend and retract synchronously.
[0020] By adopting the above technical solution, the stability of the mounting frame during lifting and lowering can be improved.
[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows: The technical solution of this application uses the output shaft of the motor to drive the adjustment plate to rotate, so that the two adjustment plates are located at the bottom of both sides of the mounting frame. The adjustment plates can limit the goods adsorbed by the vacuum suction cup. Then, the second electric push rod inside the adjustment plate pushes the pallet to rise, so that the pallet supports the goods from the bottom. The combination of vacuum suction cup pre-fixation and mechanical pallet bottom support solves the safety hazards of vacuum suction cup leakage or power failure on the surface of goods, and prevents the goods from falling off.

[0025] In the technical solution of this utility model, the bottom end of the column 5 is fixedly connected to the base 6, which helps the column 5 to be more stably fixed on the ground.
[0026] In the technical solution of this utility model, the bottom end of the horizontal plate 4 is provided with a groove 14 that matches the slider 3 along the length direction; this facilitates the smooth sliding of the slider 3.
[0027] In the technical solution of this utility model, both the tray 10 and the adjusting plate 11 are made of stainless steel; this is beneficial to improving the corrosion resistance of the tray 10 and the adjusting plate 11 and extending their service life.
[0028] In the technical solution of this utility model, a solenoid valve is installed on the branch pipe 17; if a branch pipe 17 or its connected vacuum suction cup 8 malfunctions, the faulty area can be isolated from the main vacuum system by closing the solenoid valve of the branch pipe 17, ensuring that the other two sets of vacuum suction cups 8 can still work normally and maintain part of the equipment's operating capacity.

After the goods reach the designated position, the motor 7 first flips the adjustment plates 11 to the sides to reset the adjustment plates 11. Then, the first electric push rod 2 lowers the material and places it on the designated pallet or stacking area.
