Description

Technical Field

[0001] This utility model relates to the field of wood feeding, specifically an automatic feeding device for wood carving. Background Technology

[0002] In the field of modern wood carving, the degree of automation in the wood loading process directly affects production efficiency and processing quality. Traditional wood loading relies primarily on manual operation, requiring workers to frequently move wood to the carving machine's worktable. This is not only extremely labor-intensive, but the instability of manual operation also easily leads to wood positioning deviations, affecting carving accuracy and reducing the finished product's pass rate. Furthermore, prolonged, high-intensity manual handling exposes workers to significant safety risks, such as personal injury caused by wood slipping or colliding.

[0003] With the continuous advancement of industrial automation technology, some enterprises have begun to try using automated feeding equipment to replace manual operations. Some existing automated feeding equipment stacks timber inside boxes to increase storage capacity. However, this overlapping stacking method brings new problems. The upper layer of timber is obstructed by the lower layer, leaving no clamping space for the clamping structure to operate, making it difficult for the clamping mechanism to accurately grasp the timber. Forcing clamping can easily cause the timber to tip over, become misaligned, or even damage the clamping equipment, reducing feeding efficiency and increasing equipment maintenance costs.

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automatic feeding device for wood carving to solve the shortcomings of the prior art.

[0005] The purpose of this utility model is achieved through the following technical solution: an automatic feeding device for wood carving, including a wood stacking box and a gantry conveyor mechanism. The top of the wood stacking box is provided with a stacking groove, and the wood is stacked in the stacking groove along the height direction of the wood stacking box. A discharge port is provided on one side wall of the wood stacking box, and a push port is provided on the other side wall of the wood stacking box. The push port and the discharge port are arranged opposite to each other. Both the discharge port and the push port are connected to the stacking groove. A push plate is provided on the outside of the wood stacking box. The push plate has the freedom to move in the horizontal direction. The push plate enters from the push port and pushes the wood out from the discharge port.

[0006] The gantry conveyor mechanism includes a conveyor frame, a lifting plate, a sliding plate, and finger cylinders. The conveyor frame moves in a direction parallel to the pushing plate. The lifting plate is mounted on the conveyor frame and has the freedom to move along the height of the timber stacking box. The sliding plate is slidably mounted on the lifting plate and moves in a direction perpendicular to the conveyor frame. Two finger cylinders are symmetrically mounted on the bottom of the sliding plate. The pushing plate pushes out a portion of the timber, exposing both sides of the timber in the clamping position of the finger cylinders.

[0007] Furthermore, a fixing frame is provided on the outside of the timber stacking box, and a push cylinder is horizontally installed on the fixing frame. The telescopic shaft of the push cylinder is connected to a push plate.

[0008] Furthermore, the bottom of the timber stacking box is provided with a lifting opening that connects to the stacking slot, and a lifting plate is provided below the timber stacking box. The lifting plate enters the stacking slot through the lifting opening and lifts the timber.

[0009] Furthermore, a lifting cylinder is vertically installed below the timber stacking box, and the telescopic shaft of the lifting cylinder is connected to the lifting plate.

[0010] Furthermore, a first linear drive module is arranged on both sides of the timber stacking box, and the two ends of the bottom of the conveyor frame are respectively mounted on the slides of the two first linear drive modules.

Detailed Implementation

[0019] Example 1

[0020] like Figure 1 and Figure 2As shown, an automatic feeding device for wood carving includes a wood stacking box 1 and a gantry conveyor mechanism. The top of the wood stacking box 1 has a stacking groove 2, and wood is stacked in the stacking groove 2 along the height direction of the wood stacking box 1. One side wall of the wood stacking box 1 has a discharge port 3, and the other side wall has a pusher port 4. The pusher port 4 is opposite to the discharge port 3, and both the discharge port 3 and the pusher port 4 are connected to the stacking groove 2. A pusher plate 5 is provided on the outer side of the wood stacking box 1, and the pusher plate 5 has the ability to move horizontally. The pusher plate 5 enters from the pusher port 4 and pushes the wood out from the discharge port 3. The gantry conveyor mechanism includes a conveyor frame 6, a lifting plate 7, a sliding plate 8, and finger cylinders 9. The moving direction of the conveyor frame 6 is parallel to the moving direction of the pusher plate 5. The lifting plate 7 is mounted on the conveyor frame 6 and has the freedom to move along the height direction of the wood stacking box 1. The sliding plate 8 is slidably mounted on the lifting plate 7, and the moving direction of the sliding plate 8 is perpendicular to the moving direction of the conveyor frame 6. Two finger cylinders 9 are symmetrically installed at the bottom of the sliding plate 8. The pusher plate 5... The wood is partially pushed out, exposing both sides of the wood to the clamping positions of the finger cylinders 9. The pusher plate 5 enters the stacking trough 2 through the pusher port 4, pushing the wood to move. This causes the wood cylinder outlet 3 to move, and the wood is not completely pushed out; only a portion of the wood is pushed out, exposing both sides of the wood. This allows the sides of the wood to enter the clamping positions of the finger cylinders 9, enabling the two finger cylinders 9 to clamp the sides of the wood respectively, achieving automatic feeding and clamping of the wood. Through the sliding of the conveyor frame 6 and the slide plate 8, the finger cylinders 9 clamp the wood. The board has two degrees of freedom of movement on the horizontal plane, namely the X and Y axes. By moving the lifting plate 7, the finger cylinder 9 can clamp the board and move it in the vertical direction, thus clamping the board in three directions of X, Y, and Z. The clamped board can be transported to the tooling platform of the engraving machine. When unloading, one end of the board is placed on the tooling platform so that the finger cylinder 9 can smoothly release the wood and place it on the tooling platform. Subsequently, the board is pushed into the tooling position of the tooling platform manually or by cylinder.

[0021] Furthermore, it also includes a support platform 18, on which a positioning groove 19 is provided. An annular boss 20 is fixed on the inner wall of the positioning groove 19. The timber stacking box 1 is adapted to the positioning groove 19 and supported by the annular boss 20, which can position the timber stacking box 1 so that the pusher plate 5 can smoothly enter the stacking groove 2 through the pusher port 4 to push the wooden board. After the timber in the timber stacking box 1 is loaded, the fully loaded timber stacking box 1 can be directly replaced.

[0022] Example 2

[0023] Based on Embodiment 1, a fixing frame 10 is provided on the outside of the timber stacking box 1. A push cylinder 11 is horizontally installed on the fixing frame 10. The telescopic shaft of the push cylinder 11 is connected to the push plate 5. By pushing the extension and retraction of the push cylinder 11, the push plate 5 is moved to push the timber part out of the timber stacking box 1.

[0024] Example 3

[0025] Based on Embodiment 2, the bottom of the timber stacking box 1 is provided with a lifting opening 12 that connects to the stacking groove 2. A lifting plate 13 is provided below the timber stacking box 1. The lifting plate 13 enters the stacking groove 2 through the lifting opening 12 to lift the timber. A lifting cylinder 14 is vertically installed below the timber stacking box 1. The telescopic shaft of the lifting cylinder 14 is connected to the lifting plate 13. The telescopic movement of the lifting cylinder 14 drives the lifting plate 13 to move up and down. The lifting plate 13 supports the stacked wooden boards and drives the timber to move upward. After the top timber is loaded, the lifting plate 13 moves upward by the thickness of one wooden board, so that the next timber is on the moving path of the pusher plate 5, thereby realizing the one-by-one loading of stacked timber.

[0026] Example 4

[0027] Based on Example 3, such as Figure 1 and Figure 2 As shown, a first linear drive module 15 is arranged on both sides of the timber stacking box 1. The bottom ends of the conveyor frame 6 are respectively mounted on the slides of the two first linear drive modules 15. A feeding cylinder 16 is vertically mounted on the conveyor frame 6. The telescopic shaft of the feeding cylinder 16 is connected to the lifting plate 7. A second linear drive module 17 is mounted on the bottom of the lifting plate 7. A slide plate 8 is mounted on the slide of the second linear drive module 17. The first linear drive module 15 drives the conveyor frame 6 to move, the second linear drive module 17 drives the slide plate 8 to move, and the telescopic movement of the feeding cylinder 16 drives the lifting plate 7 to move up and down, thus enabling the clamping of the wooden board in the X, Y, and Z axes. A lead screw groove is provided at the bottom of the slide plate 8. A bidirectional threaded screw 21 is rotatably mounted in the groove. Screw sliders 22 are threaded onto the two opposite threaded sections of the bidirectional threaded screw 21. Two finger cylinders 9 are respectively mounted on the two screw sliders 22. The bidirectional threaded screw 21 is driven by a motor, causing it to rotate and the two screw sliders 22 to move in opposite directions, thereby adjusting the distance between the two finger cylinders 9. Before clamping the wooden board, the distance between the two finger cylinders 9 is greater than the width of the wooden board. When the finger cylinders 9 move to the side of the wooden board, the two finger cylinders 9 move closer to the wooden board, causing the side of the wooden board to move into the gripper of the finger cylinders 9. By clamping the wooden board with the finger cylinders 9, the clamped wooden board can be transported to the tooling platform of the engraving machine.
