Detailed Implementation

[0015] The directional terms mentioned in the following embodiments, such as "up", "down", "left", and "right", are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the invention of this utility model.

[0016] like Figure 1-5As shown, a wood veneer stacking and slicing line device includes a frame 1, on which a first lifting and conveying assembly 2 for initial feeding, a second lifting and conveying assembly 3 for secondary feeding, and a feeding assembly 4 for lateral feeding are installed. The feeding assembly 4 includes a feeding mounting frame 41, on which a friction roller 42 for rubbing the wood veneer and a feeding drive device 43 for driving the friction roller 42 to rotate are installed. Through the coordinated operation of the first lifting and conveying assembly 2, the second lifting and conveying assembly 3, and the feeding assembly 4, a continuous process can be achieved for the veneer stack from initial loading to secondary loading and then to lateral material transport, reducing manual operation and improving the overall automation level of the operation. The first lifting and conveying assembly 2 includes a first bracket 21 and a first lifting drive device 22, the output end of which is connected to the second bracket 31. The second lifting and conveying assembly 3 includes a second bracket 31 and a second lifting drive device 32, the output end of which is connected to the second bracket 31. A robotic arm assembly is installed on the second bracket 31, and the robotic arm assembly includes an opening and closing drive group. Component 323 includes a first cross fork 324 and a second cross fork 325 for actively picking up a portion of the material for feeding. The opening and closing drive assembly 323 drives the first cross fork 324 and the second cross fork 325 to move away from or towards each other. The relative movement design of the first cross fork 324 and the second cross fork 325 can accurately pick up the veneer stack, avoid damage to the veneer during the picking process, and ensure the quality of the veneer. The first cross fork 324 and the second cross fork 325 are set between the first bracket 21 and the friction roller 42. They pick up the veneer stack and send it to the friction roller 42. The friction roller 42 performs segmented lateral movement, which can realize uninterrupted conveying, reduce intermediate feeding waiting time, and greatly improve production efficiency.

[0017] Specifically, the first bracket 21 and the second bracket 31 are both slidably connected to the frame 1, so that the first bracket 21 and the second bracket 31 can move stably on the frame 1, ensuring that there will be no shaking or deviation during the lifting process, and ensuring the stability of the wood veneer stack during the transportation process.

[0018] Specifically, a slider 2122 is fixedly connected to the side of the first bracket 21, and a slide rail 2121 is fixedly connected to the frame 1. The slide rail 2121 extends vertically, and the slider 2122 slides vertically and is connected to the slide rail 2121, providing precise guidance for the vertical sliding of the first bracket 21, so that the first bracket 21 can move according to the predetermined trajectory, further improving the accuracy of the veneer stack conveying.

[0019] Specifically, a guide rod 311 is fixedly connected to the second bracket 31, and a slide groove is provided on the top of the frame 1. The guide rod 311 is slidably connected to the slide groove, providing stable support and guidance for the up and down movement of the second bracket 31, preventing the second bracket 31 from tilting during the lifting process, and ensuring the normal operation of the robot arm components.

[0020] Specifically, the opening and closing drive assembly 323 includes a first opening and closing cylinder 3231 and a second opening and closing cylinder 3232 mounted on the second bracket 31. The output ends of the first opening and closing cylinder 3231 and the second opening and closing cylinder 3232 are arranged facing each other. The output end of the first opening and closing cylinder 3231 is connected to a first cross fork 324 that is laterally slidably connected to the second bracket 31, and the output end of the second opening and closing cylinder 3232 is connected to a second cross fork 325 that is laterally slidably connected to the second bracket 31. This assembly can precisely control the movement of the first support rod and the second support rod, thereby achieving precise opening and closing of the first cross fork 324 and the second cross fork 325 and improving the efficiency of picking up the veneer stack.

[0021] Specifically, multiple feeding conveyor rollers 211 are rotatably connected to the first bracket 21, which allows the veneer stack to move smoothly on the first bracket 21, reduces the friction between the veneer and the bracket, and prevents the veneer from being damaged during the conveying process.

[0022] Specifically, a wood veneer stack conveyor line 5 is spaced apart on one side of the feeding conveyor roller 211, and the wood veneer stack conveyor line 5 is gap-connected with the first bracket 21. The gap connection between the wood veneer stack conveyor line 5 and the first bracket 21 enables seamless transfer of the wood veneer stack from the conveyor line to the first bracket 21, reducing the downtime of the wood veneer stack during the transfer process, improving conveying efficiency, and also allowing single or multiple pieces to be transported and then stacked on the first bracket 21.

[0023] Specifically, the first bracket 21 is equipped with a first limiting plate for limiting the lateral position of the veneer stack and a second limiting plate for limiting the longitudinal position of the veneer stack. This accurately limits the position of the veneer stack on the first bracket 21, preventing the veneer stack from shifting during transport and ensuring the accuracy of subsequent forklift picking and transport.

[0024] Specifically, the feeding assembly 4 also includes a feeding active idler roller 44 and a feeding driven pressure roller 45. The friction roller 42 is positioned higher than the feeding active idler roller 44. The feeding active idler roller 44 is rotatably connected to the feeding mounting frame 41. A feeding transition roller 46 is also rotatably connected to the feeding mounting frame 41. The feeding transition roller 46 is located between the friction roller 42 and the feeding active idler roller 44 and is not lower than the feeding active idler roller 44, serving as an intermediate transition. The feeding drive device 43 is mounted on the feeding mounting frame 41. 3. A servo motor is used to drive the friction roller 42 and the feed transition roller 46 via a belt. The feed transition roller 46 has a drive gear 47 fixedly connected to its end. The same end of the feed drive roller 44 has a driven gear 48 fixedly connected to it. The drive gear 47 meshes with the driven gear 48, thereby transmitting power to the feed drive roller 44. This ensures the stability and accuracy of power transmission and coordinates the rotation speed of the feed drive roller 44 and the friction roller 42, keeping the veneer stable during the conveying process.

[0025] Specifically, the feeding mounting frame 41 is equipped with a feeding gap adjustment frame 49 and a feeding gap adjustment drive device 410. The feeding gap adjustment frame 49 is hinged to the feeding mounting frame 41, the feeding driven pressure roller 45 is rotatably connected to the feeding mounting frame 41, and the feeding gap adjustment drive device 410 is hinged to and driven by the feeding mounting frame 41. By driving the feeding gap adjustment frame 49 through the feeding gap adjustment drive device 410, the gap between the feeding active roller 44 and the feeding driven pressure roller 45 can be flexibly adjusted to accommodate veneers of different thicknesses and specifications, ensuring that the veneers can be stably clamped and smoothly conveyed.

[0026] Specifically, both the first lifting drive device 22 and the second lifting drive device 32 employ belt lifting assemblies. Specifically, the first lifting drive device 22 includes a first lifting motor 221 and two first lifting belts 222. The first lifting motor 221 drives the two first lifting belts 222 to rotate via a reducer. The two sides of the first bracket 21 are fixedly connected to the two first belts, thereby achieving the lifting and lowering of the first bracket 21. Similarly, the second lifting drive device 32 includes a second lifting motor 321 and two second lifting belts 322. The second lifting motor 321 drives the two second lifting belts 322 to rotate via a reducer. The two sides of the second bracket 31 are fixedly connected to the two second belts, thereby achieving the lifting and lowering of the second bracket 31. This evenly distributes the weight, making the lifting process more stable, reducing swaying caused by uneven force, and extending the service life of the equipment. In another embodiment, the second bracket 31 is moved up and down using a chain lifting mechanism from the prior art. Figure 4 The position of the guide rod 311 shown is directly replaced by the position of the chain, and the second bracket 31 is lifted directly by the chain.

[0027] Work process: The veneer stack is conveyed onto the feeding conveyor roller 211 via the veneer stack conveyor line 5. The first lifting drive device 22 drives the first bracket 21 to rise, and the opening and closing drive assembly 323 drives the first cross fork 324 and the second cross fork 325 to move away from each other. The first bracket 21 rises until the veneer stack is a certain height above the first cross fork 324 and the second cross fork 325. Then, the opening and closing drive assembly 323 drives the first cross fork 324 and the second cross fork 325 to move closer to each other and insert into the veneer stack. The second lifting drive device 32 drives the second bracket 31 to rise, and the veneer stack moves towards the friction. As roller 42 moves, the friction roller 42 rubs the veneer, moving the rubbed veneer towards the feeding transition roller 46. The feeding transition roller 46 receives and drives the veneer towards the feeding active roller 44. The feeding active roller 44 and the feeding driven pressure roller 45 clamp the veneer and drive it to continue moving. While the second support 31 continuously lifts the feed, the lower feeding conveyor roller 211 can continue to prepare stacks of veneer and lift them up in time to replenish the second support 31, thereby achieving near-zero-interruption veneer piece conveying, greatly improving transportation efficiency and overall production efficiency, and reducing production costs.
