Description

Technical Field

[0001] This utility model relates to the field of wooden pallet production technology, and in particular to a flipping mechanism for wooden pallet production. Background Technology

[0002] The flipping mechanism in wooden pallet production is a key piece of equipment in automated wooden pallet production lines. It is mainly used to adjust the posture of pallet blanks or semi-finished products during processing, facilitating double-sided processing, nailing, sanding, and other procedures. Traditional production methods rely on manual flipping, which is inefficient and labor-intensive. Modern automated production lines achieve rapid and stable posture changes through mechanical, pneumatic, or hydraulic flipping mechanisms. Common flipping mechanisms include rotary gripper types, chain-driven types, or flipping table structures.

[0003] A search revealed that patent CN218802885U discloses a wooden pallet flipping mechanism. The mechanism clamps the wooden pallet inside the flipping plate using a clamping component, drives a motor to rotate the flipping box, and flips the wooden pallet to a predetermined position, thus flipping the wooden pallet to the other side. The other side of the wooden pallet is then processed during the next flipping interval.

[0004] However, the above-mentioned flipping mechanism has the following drawbacks: after the wooden pallet enters the flipping component, it needs to be clamped and fixed by the pressure plate driven by the cylinder. Since the entire flipping component needs to rotate continuously, there are problems with the wiring of the cylinder. If the flipping component rotates back and forth, it cannot continuously flip the wooden pallet, thus affecting the flipping efficiency. Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a flipping mechanism for wooden pallet production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flipping mechanism for wooden pallet production, comprising a base plate, an intermediate frame fixedly installed in the middle of the upper surface of the base plate, a first side frame and a second side frame fixedly installed on the upper surface of the base plate and on both sides of the intermediate frame, a conveyor belt rotatably connected to the top of the first side frame, a plurality of rollers rotatably connected to the top of the second side frame, a second motor fixedly installed at the top of the intermediate frame, a flipping component fixedly connected to the output shaft of the second motor, a pushing component provided at the top of the second side frame and near the flipping component, and a controller installed on the upper surface of the base plate.

[0007] Furthermore, a first motor for driving the conveyor belt to rotate is installed on the outer wall of the first side frame.

[0008] Furthermore, the surface of the conveyor belt is fixed with several protruding ridges at equal intervals.

[0009] Furthermore, a support plate is fixed on the top of the first side frame and inside the conveyor belt, and the upper surface of the support plate is in contact with the conveyor belt.

[0010] Furthermore, the flipping assembly includes a flat plate fixedly connected to the output shaft of the second motor. Slots are provided on both sides of the flat plate, and multiple springs are fixed to the inner sidewalls of the slots. A pressure plate is fixedly connected to the other end of each spring.

[0011] Furthermore, the pressure plate is designed to be bent upwards at the end near the conveyor belt.

[0012] Furthermore, the pushing assembly includes a bracket fixed to the top of the second side frame, an electric telescopic rod fixed to the top of the bracket, a U-shaped plate fixed to the bottom telescopic end of the electric telescopic rod, a drive shaft rotatably connected inside the U-shaped plate, a third motor fixed to the outer wall of the U-shaped plate, and the output shaft of the third motor fixedly connected to the drive shaft.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model provides a flipping mechanism for wooden pallet production, which includes a base plate, an intermediate frame, a first side frame, a second side frame, a conveyor belt, a flipping component, and a second motor. After the pallet is placed on the surface of the conveyor belt at the top of the first side frame, the pallet is fed into the flat slot of the flipping component by the conveyor belt.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4 As shown, a flipping mechanism for wooden pallet production is disclosed, comprising a base plate 1, an intermediate frame 2 fixedly installed in the middle of the upper surface of the base plate 1, a first side frame 3 and a second side frame 4 fixedly installed on the upper surface of the base plate 1 and on both sides of the intermediate frame 2, a conveyor belt 5 rotatably connected to the top of the first side frame 3, a plurality of rollers 8 rotatably connected to the top of the second side frame 4, a second motor 10 fixedly installed at the top of the intermediate frame 2, a flipping component 9 fixedly connected to the output shaft of the second motor 10, a pushing component 11 provided at the top of the second side frame 4 and near the flipping component 9, and a controller installed on the upper surface of the base plate 1.

[0025] In this embodiment, the controller is a Siemens SIMATIC KP1200 series (HMI+PLC integrated machine), specifically model KP1212 Basic PN (6AV2123-2GB03-0AX0). This controller controls the operation of various electronic components of the mechanism.

[0026] A first motor 7 is installed on the outer wall of the first side frame 3 to drive the conveyor belt 5 to rotate.

[0027] In this embodiment, the conveyor belt 5 is installed using existing technology. The two ends of the conveyor belt 5 are fitted onto two shafts, one of which is fixedly connected to the output end of the first motor 7. The first motor 7 can drive the conveyor belt 5 to rotate.

[0028] Several protruding ridges 51 are fixed at equal intervals on the surface of the conveyor belt 5.

[0029] When a wooden pallet is placed on the surface of the conveyor belt 5, the rotation of the conveyor belt 5 can drive the pallet to move, and the protruding ribs 51 on the upper surface of the conveyor belt 5 can push the pallet to move, preventing the pallet from slipping.

[0030] A support plate 6 is fixed on the top of the first side frame 3 and inside the conveyor belt 5, with the upper surface of the support plate 6 in contact with the conveyor belt 5.

[0031] The support plate 6 can support the soft conveyor belt 5.

[0032] The flipping assembly 9 includes a flat plate 91 fixedly connected to the output shaft of the second motor 10. Slots are provided on both sides of the flat plate 91. Multiple springs 92 are fixed to the inner sidewall of the slots. A pressure plate 93 is fixedly connected to the other end of the multiple springs 92.

[0033] After the tray is inserted into the slots on both sides of the flat plate 91, the spring 92 presses the pressure plate 93, which then presses and fixes the tray, thus securing it to the flipping assembly 9. This allows the second motor 10 to drive the flipping assembly 9 to rotate, thereby flipping the tray.

[0034] The pressure plate 93 is designed to be bent upwards at the end near the conveyor belt 5.

[0035] When the conveyor belt 5 moves the pallet, the protruding rib 51 pushes the pallet into the pressure plate 93. The pressure plate 93 is designed to bend upwards, making it easier for the pallet to be inserted into the pressure plate 93.

[0036] The feeding assembly 11 includes a bracket 111 fixed to the top of the second side frame 4. An electric telescopic rod 112 is fixed to the top of the bracket 111. A U-shaped plate 113 is fixed to the bottom telescopic end of the electric telescopic rod 112. An active shaft 114 is rotatably connected inside the U-shaped plate 113. A third motor 115 is fixed to the outer wall of the U-shaped plate 113. The output shaft of the third motor 115 is fixedly connected to the active shaft 114.

[0037] After the flipping assembly 9 flips the tray onto the surface of the roller 8, the electric telescopic rod 112 lowers the U-shaped plate 113 and the drive shaft 114, causing the drive shaft 114 to press against the tray surface. Then, the third motor 115 is activated to rotate the drive shaft 114, thereby using friction to push the tray out of the slot in the plate 91. The drive shaft 114 is equipped with a rubber sleeve to increase friction, which is greater than the friction between the tray and the pressure plate 93. Furthermore, when the drive shaft 114 is in its initial position at the top of the bracket 111, its height will not hinder the flipping of the tray.

[0038] Working principle: The pallet is placed on the surface of the conveyor belt 5. The first motor 7 drives the conveyor belt 5 to rotate, thereby pushing the pallet into the slot on the left side of the plate 91. The pressure plate 93 is used to press and fix the pallet. Then, the second motor 10 drives the plate 91 to rotate 180°, and the pallet falls on the surface of the roller 8. Subsequently, the electric telescopic rod 112 drives the drive shaft 114 to descend and press the pallet. Finally, the third motor 115 drives the drive shaft 114 to rotate, thereby pushing the pallet out of the slot of the plate 91.

[0039] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
