Description

A double-claw conveying device for veneer cutting and gluing

This project is about veneer processing technology, specifically a double-claw conveying device used for cutting and gluing veneer.

In conventional veneer cutting and processing conveying devices, an operator places uncut veneer on the conveyor platform of the conveyor and operates the conveyor's clamping jaws to grip the uncut veneer. The clamping jaws and conveyor platform then move the uncut veneer from a first position (where the operator places the uncut veneer on the conveyor belt) to a second position (where the processing unit will cut and glue the uncut veneer). The clamping jaws and conveyor platform remain in the second position until the veneer is cut and glued, at which point they return to the first position. During this period, the operator is unable to place a new batch of uncut veneer on the conveyor platform and operate the clamping jaws, which limits the production efficiency of conventional veneer cutting and processing conveying devices.

Therefore, the existing technology is in urgent need of improvement to provide an overall solution for the conveying device that can improve the efficiency of veneer cutting and gluing.

In view of the fact that the above-mentioned existing double-gripper conveying devices used for cutting and gluing veneer still have many shortcomings, the purpose of this invention is to provide a double-gripper conveying device for cutting and gluing veneer, which can clamp one side of the veneer for conveying. After the first batch of uncut veneer is fed into the processing device, it can return to its original position to be replenished with a new batch of uncut veneer without waiting for the processing device to complete cutting and gluing, thereby making processing faster and helping to improve overall work efficiency.

In order to achieve the above-mentioned creative purpose, this invention provides a double-claw conveying device for cutting and gluing veneer, which is used in conjunction with a processing unit. The processing unit includes a base, a cutting group for cutting the veneer, and a gluing group for gluing the veneer; the double-claw conveying device is used to convey a veneer, which includes a front conveying unit located on one side of the processing unit for conveying the veneer onto the base; the front conveying unit includes a front stage group that moves back and forth relative to the processing unit and is used to place the veneer, a front clamping group that moves back and forth relative to the front stage group, and a front driving group that drives the front clamping group to move; the front stage group has a front plate formed with multiple front seams and used to place the veneer, and the front clamping group has multiple front seams that can be used to The front clamping claw moves in the front seam of the front stage assembly, and the front clamping claw has a front lower clamping block and a front upper clamping block that clamps one side of the veneer with the front lower clamping block; a rear conveying unit is located on the other side of the processing unit and is used to move the veneer out of the support platform; the rear conveying unit includes a rear stage assembly that moves back and forth relative to the processing unit and is used to place the veneer, and a Regarding the rear clamping group that moves back and forth on the rear stage group, and a rear driving group that drives the rear clamping group to move; the rear stage group has a rear table with multiple rear seams formed on it and used to place the veneer, the rear clamping group has multiple rear clamping claws that can move in the rear seams of the rear stage group, and the rear clamping claws have a rear lower clamping block and a rear upper clamping block that clamps the other side of the veneer with the rear lower clamping block.

Through the above-mentioned structure, this innovative dual-gripper conveying device for veneer cutting and gluing achieves the simultaneous or sequential delivery of cut veneer and the rapid delivery of uncut veneer to the processing unit through the collaborative design of the rear and front clamping groups, thereby achieving efficient and continuous operation. Specifically, the rear and front clamping groups are located in different areas and operate in parallel. The rear clamping group is responsible for delivering the cut veneer, while the front clamping group is responsible for delivering the uncut veneer to the cutting area. This design avoids functional interference between the front and rear clamping groups and ensures a seamless veneer conveying process. In each cycle, after the rear clamping group finishes delivering the cut veneer, the front clamping group immediately clamps and feeds in the uncut veneer. The front and rear clamping jaws coordinate to adjust the clamping to ensure the stability and precise alignment of the veneer during transportation, avoiding deviation or slippage. In addition, the operation of the front and rear clamping jaws is achieved through precise control, ensuring an uninterrupted cutting process. To further improve efficiency, this creation can also introduce an automatic adjustment device to adjust the clamping according to the thickness of the veneer to ensure smooth transportation of the veneer. Overall, this creation achieves continuous veneer transportation through the coordinated design of the front and rear clamping groups, minimizes the operator's idle time, and improves overall production efficiency.

The rear conveyor unit 4 comprises a rear base assembly 60, a rear platform assembly 70, two rear clamping assemblies 80, and a rear drive assembly 90. These components work together to ensure that the veneer W is stably conveyed and accurately aligned during processing.

The rear stage assembly 70 includes a rear stage frame 71, a rear slide 72, a plurality of rear plates 73, and a plurality of rear rollers 74. The rear stage frame 71 is driven to move forward and backward on the rear base assembly 60 (the driving components are not shown). The rear slide 72 is mounted on the rear stage frame 71. The rear plates 73 are mounted on the rear stage frame 71. The rear rollers 74 are rotatably mounted on the rear stage frame 71 to transport the veneer W. Each rear platen 73 is spaced apart to form a rear seam G2 corresponding to the support seam 111. In this embodiment, there are six rear seams G2. Adjacent rear seams G2 form a rear seam distance P2. The rear seam distance P2 near the center is greater than the rear seam distance P2 near the left and right sides to ensure precise alignment and smooth conveyance of the veneer W.

The rear drive assembly 90 comprises a rear motor 91, a rear shaft 92, multiple rear gears 93, and two rear belts 94. The rear motor 91 provides power. The rear shaft 92 is pivoted on the rear frame 71 and receives power directly or indirectly from the motor 91. The rear gears 93 are connected to the rear shaft 92 and pivoted on the rear frame 71, respectively. The rear belts 94 are sleeved around the rear gears 93. The rear belts 94 connect to the rear clamping frame 82, which in turn drives the rear clamping assembly 80 forward and backward, ensuring accurate and stable delivery of the veneer W to subsequent processes.

The operating sequence of this embodiment is described as follows:

As shown in Figure 13, when the front conveyor unit 3 is activated, the veneer W enters the conveying area and is taken over by the front conveyor unit 3. The front assembly 30 firmly supports the veneer W, ensuring that it does not shift during the conveying process. Subsequently, the front clamping assembly 40 begins to clamp the veneer W, holding it firmly according to the set clamping force. The front clamping assembly 40 clamps the veneer W using the front lower clamping block 433 and the front upper clamping block 438, and slides on the front slide 32 via the front slide 41. The front drive assembly 50 then drives the front clamping assembly 40 to move, pushing the veneer W onto the support platform 11.

When the front clamping claw 43 moves toward the support platform 11 and abuts against it, the rear clamping claw 83 moves toward the support platform 11 and maintains a certain distance. In this way, the clamping sequence is correct and the conveying efficiency is accelerated.

At this point, the pressure beam 12 applies pressure, ensuring the stability of the veneer W during the cutting and gluing process. When the cutting process begins, the cutting assembly 13 begins operation. While the veneer W is clamped by the front clamping assembly 40, the cutting assembly 13 cuts one edge of the veneer W. The cutting assembly 13 is precisely designed to ensure a smooth edge. Subsequently, the gluing assembly 14 applies glue to one edge of the veneer W, ensuring that the veneer W can be glued together in multiple layers.

As shown in Figure 14, the rear conveyor unit 4 begins preparing to receive the cut veneer W, while the front conveyor unit 3 returns to its original position to receive the uncut veneer W. After the veneer W is clamped by the rear clamping assembly 80, the cutting assembly 13 cuts the other edge of the veneer W. Subsequently, the gluing assembly 14 applies glue to the other edge of the veneer W.

As shown in Figure 15, the rear clamping group 80 now starts working and receives the finished veneer W sent from the cutting area. When the rear clamping group 80 detects the cut veneer W, it will send it out to ensure that the veneer W does not get stuck and remains stable. At the same time, the front clamping group 40 sends new uncut veneer W into the cutting area and clamps it. The front clamping group 40 and the rear clamping group 80 work together to ensure the continuous conveyance of veneer W. The operation of the two is synchronized. When the rear clamping group 80 sends out the cut veneer W, the front clamping group 40 will simultaneously or with minimal delay send new veneer W into the cutting area to ensure the continuity of the cutting process and reduce any blank time. The coordinated operation of the front and rear double clamps ensures the smooth progress of the veneer W-cutting process, realizes continuous conveying, and thus improves production efficiency.

Based on the thickness of the veneer W, the front and rear clamping jaws 43 and 83 automatically adjust to ensure precise cuts. After completing a round of cutting and conveying, the front and rear clamping assemblies 40 and 80 work together again to convey the uncut veneer W to the cutting area and remove the cut veneer W. This entire system operates in a continuous cycle, ensuring efficient and stable automated operation.

When the front clamping assembly 40 and the rear clamping assembly 80 clamp the veneer W, they will slightly lift the veneer W to prevent it from directly contacting the surface of the table, thereby reducing friction and ensuring that the veneer W will not get stuck or become uneven due to friction.

The front assembly 30 allows the veneer W to enter the processing area smoothly. The front clamping assembly 40 securely holds the veneer W before processing. The rear assembly 70 ensures the processed veneer W is smoothly transported. The rear clamping assembly 80 maintains the stability of the processed veneer W during transport. Through this device, this invention achieves rapid cutting and smooth transport of the veneer W, thereby improving production efficiency, ensuring the cutting precision of each piece of veneer W, and ensuring the efficient and stable operation of the entire production process.

In this invention's dual-gripper conveying device 1 for veneer cutting and gluing, the front clamping assembly 40 cuts one side of the veneer, while the rear clamping assembly 80 cuts the other side. The two work together to achieve a continuous and efficient cutting process. The front clamping assembly 40 and the rear clamping assembly 80 are responsible for the stable conveyance of the veneer, ensuring the precision of each cut and the precise alignment of the veneer. This enables efficient and accurate veneer cutting, meeting the needs of large-scale production.
