Description

A fully automatic stacking machine for irregular shapes and its control system Technical Field

[0001] This invention pertains to stacking machine equipment, specifically relating to a fully automatic stacking machine for irregular shapes and its control system. Background Technology

[0002] Stacking machines are a common piece of equipment in the field of sheet metal transportation. They can stack multiple sheets together to facilitate subsequent processing or transportation. Stacking machines can reduce production costs, improve production efficiency, and reduce manual operation.

[0003] Existing invention patent number 202111238682.6 provides a stacking device for a sheet metal production line. It utilizes a threaded rod connected to a fixed frame to move side plates A and B, effectively adjusting their positions according to the sheet metal dimensions. This allows for more efficient fixing and limiting of the sheets, preventing tipping and displacement. However, this technical solution can only accurately stack standard-shaped sheets such as rectangles and circles using two side plates. It cannot accurately limit the placement of irregularly shaped sheets, resulting in stacked sheets with inconsistent orientations, which is inconvenient for subsequent packaging and transportation.

[0004] In addition, those skilled in the art can design positioning devices based on the specific shape and size of the irregularly shaped plates to complete the positioning and stacking of the irregularly shaped plates. However, such stacking devices have poor adaptability and can only complete the stacking of corresponding irregularly shaped plates. Therefore, there is an urgent need in the art for a device that can complete the stacking of various irregularly shaped plates. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned technical problems, the present invention provides an irregularly shaped fully automatic stacking machine, which adopts a bidirectional conveying component and stacks boards at four stations simultaneously, resulting in high stacking efficiency. The positioning device can automatically adjust according to boards of different sizes and shapes to complete the positioning and stacking of boards.

[0011] The sheet material pushing component is located on the left and right sides of the sheet material conveying component below the sheet material handling component;

[0012] A flexible positioning component is located on the outside of the sheet material pushing component;

[0013] A sheet metal stacking box is located between the sheet metal pushing component and the flexible positioning component;

[0014] The flexible positioning component includes:

[0015] Positioning pin;

[0016] The positioning slider is in the shape of a long strip, with multiple positioning pins fixedly installed on the front of the positioning slider. The top of the positioning slider is provided with a movable slider, and the positioning slider has multiple such sliders.

[0017] The top slide plate has a first slide rail at the bottom, which matches the movable slider. The positioning slider is slidably installed at the bottom of the top slide plate.

[0018] A rotating push rod extends along the inside of the top slide plate to the front of the positioning slider. A limiting head is provided at the front end of the rotating push rod. The top of the positioning slider is sleeved on the rotating push rod. The rotation of the rotating push rod drives the positioning slider to move back and forth. The number of rotating push rods and positioning sliders is the same.

[0019] The limiting groove is fixedly installed at the rear end of the rotating push rod and has a hexagonal groove inside.

[0020] The limiting pin has a front half whose shape and size match the hexagonal groove of the limiting slot, and a rear half that is cylindrical.

[0021] The locking head is fixed in a gear shape to the rear half of the limiting pin;

[0022] The positioning box is installed below the top slide plate, and the rear half of the limiting pin extends outward from the inside of the positioning box.

[0023] The positioning plate is slidably mounted on the positioning box above the positioning head, and the bottom of the positioning plate has a groove that matches the gear of the positioning head;

[0024] The plate handling component transports the plate to the plate pushing component, which pushes the plate onto the plate stacking box and aligns it using the flexible positioning component.

[0025] In some embodiments of the present invention, the sheet metal handling assembly includes: a handling slide plate, which is vertically mounted on the upper side of the sheet metal conveying assembly via a support frame, and a first slide rail is provided on the lower surface of the handling slide plate;

[0026] The first ball screw assembly is located inside the transport slide plate;

[0028] A fixed plate is fixedly installed between four sliding fixed rods, and a rotary telescopic motor is provided at the bottom of the fixed plate;

[0029] A sliding plate is located below the rotary telescopic motor and is slidably installed between four sliding fixed rods. The rotary telescopic motor's rotary telescopic rods extend downward through the sliding plate.

[0030] A suction cup plate is fixedly installed at the lower end of the rotating telescopic rod. The bottom of the suction cup plate is provided with multiple suction cups, which are connected to an air pump installed above the sliding plate.

[0031] In some embodiments of the present invention, the plate pushing assembly includes:

[0032] A push base plate is located between the sheet material conveying assembly and the sheet material stacking box, and a second slide rail is provided on the upper surface of the push base plate;

[0033] The second ball screw assembly is located inside the push base plate;

[0034] A telescopic motor is slidably mounted on the push base plate via a second slide rail and connected to a second ball screw pair;

[0037] The stacked housing is located between the plate pushing component and the flexible positioning component;

[0038] The lifting device is located at the bottom of the stacking box;

[0040] In some embodiments of the present invention, both the first conveying unit and the second conveying unit consist of a frame, a conveying roller mounted on the frame, and a plate baffle.

The image comparison unit compares the preset posture of the boards with the posture before stacking and transmits the difference value to the microprocessor. The microprocessor controls the board handling component to adjust the boards to the preset posture. The microprocessor controls the board handling component through the control panel to stack the boards with the adjusted posture onto the board pushing component. The board pushing component pushes the stacked boards above the board stacking box. At this time, the stacked boards are adjusted a second time by a flexible positioning component. Then, the board stacking box takes in the stacked boards.

[0044] (III) Beneficial Effects

[0045] As can be seen from the above technical solution, the present invention has at least one of the following beneficial effects:

[0046] The sheet metal conveying assembly of the present invention is provided with a first conveying section and a second conveying section for opposite conveying. Sheets are conveyed from two opposite directions. The sheet metal handling assembly is provided in two sets, both arranged vertically. Each set of sheet metal handling assemblies is provided with two sets of sheet metal handling systems. When one set of sheet metal handling systems in the sheet metal handling assembly moves the sheet metal conveyed by the sheet metal conveying assembly to the sheet metal pushing assembly on the left, the other set of sheet metal handling systems is directly above the sheet metal conveying assembly. Therefore, the sheet metal handling assembly can complete the handling of two sheets in one stroke, and the sheet metal handling efficiency is effectively improved. Correspondingly, sheet metal pushing assemblies, flexible positioning assemblies and sheet metal stacking boxes are provided at both ends of the sheet metal handling assembly. Each component works independently. Therefore, the present invention can provide four workstations for stacking work at the same time, and the stacking efficiency of the sheet metal is high.

[0047] This invention employs multiple positioning pins in its flexible positioning component to position irregularly shaped sheets. Before the stacking machine begins stacking the sheets, a sample sheet is used to adjust the flexible positioning component. The sample sheet is pushed backward against the positioning pins, causing the positioning pins to be under force and move the positioning slider backward at the bottom of the fixed plate. The rotating push rod rotates. After the positioning pins are adjusted, the operator uses a locking head to push the limiting pin into the limiting groove at the rear end of the rotating push rod. The limiting pin can be rotated to fit the limiting groove. Then, the positioning locking plate slides downward, and the groove at the bottom of the positioning locking plate fixes a row of locking heads. By restricting the rotation of the rotating push rod, the forward and backward displacement of the positioning slider is limited. At this point, the flexible positioning component is adjusted, and the multiple positioning pins form an arc-shaped recess that matches the irregularly shaped sheet. The height of this arc-shaped recess is greater than the height of the stacked irregularly shaped sheets. The flexible positioning component provided by this invention can adjust itself according to the specific size and shape of the irregularly shaped sheet, making the stacking device cost-effective and highly adaptable.

[0048] The present invention also provides a control system, which includes an image recognition module. During the process of the board being transported by the board handling device, the image recognition module reads the posture of the board and compares the image of the board with a preset image. Then, the difference value is transmitted to the microcontroller. The microcontroller controls the rotation of the rotary telescopic motor through the control panel to adjust the board to the preset posture, completing the first posture adjustment of the board. When the board is stacked to a specified height on the board pushing device, the board pushing device pushes the stack of boards forward to the flexible positioning component to complete the second positioning. The stacked boards are aligned in the same direction with extremely high accuracy. Attached Figure Description
