Description

Technical Field

[0001] This invention relates to the field of square timber processing technology, and more specifically, to a material preparation and conveying device for automatic square timber stacking. Background Technology

[0002] The plywood industry uses a large amount of square timber, which needs to be stacked before being placed in a drying kiln for drying. The drying kiln has strict requirements on the specifications and stacking direction of the stacked square timber; otherwise, the drying quality or the kiln loading density will be affected.

[0003] Currently, fully automatic timber stacking machines are available, but they are generally used independently and not integrated into a continuous production line with the preceding log sawing process. This necessitates manual transfer of the timber produced in the preceding process to the front-end device of the fully automatic timber stacking machine—the automatic log sawing unit—to distribute and arrange the sawn timber to the required specifications before feeding it into the fully automatic stacking machine. Because there is no transition equipment between the fully automatic timber stacking machine and the automatic log sawing unit, manual operation is required. This manual operation not only increases manpower and labor intensity but also negatively impacts the production efficiency and cost of the subsequent fully automatic timber stacking machine.

[0004] In addition, after the fully automatic timber stacking machine completes a standard timber stack, it needs to remove the timber stack and prepare for the next round of timber stacking. This process takes 2-5 minutes, so the previous process has to stop processing and wait for the timber stack to be removed, which greatly affects the production rhythm and efficiency of the entire timber stacking machine. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a material preparation and conveying device for automatic stacking of square timber. This material preparation and conveying device can realize log sawing, automatic buffering of sawn square timber, and automatic arrangement and conveying by docking with a fully automatic square timber stacking machine. It can not only connect the square timber sawing process and the stacking process into a complete fully automatic production line, reducing personnel configuration, but also significantly improve the production efficiency of the fully automatic square timber stacking machine.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a material preparation and conveying device for automatic stacking of square timber, characterized in that it comprises:

[0007] Automatic log sawing device used for sawing logs into square timber and for quick-change saw blades;

[0008] A timber stacking device for forming longitudinally arranged timber stacks from sawn timber;

[0009] An automatic timber conveying and distributing device for flipping longitudinally arranged timber groups to allow the timbers to be conveyed in a transverse arrangement.

[0010] And a buffer silo for buffering longitudinally arranged square timber groups;

[0011] The automatic log sawing device, the square timber sorting device, and the automatic square timber conveying and distributing device are connected in sequence. The automatic square timber conveying and distributing device is connected to the fully automatic square timber stacking machine. The automatic square timber conveying and distributing device includes a conveying mechanism, a turning mechanism, and a square timber transverse arrangement mechanism. One end of the square timber sorting device is connected to the automatic log sawing device, and the other end is connected to the conveying mechanism. The other end of the conveying mechanism is connected to the buffer silo.

[0012] The conveying mechanism is equipped with several flipping stations. The flipping mechanism is located on the side of the flipping station and extends into the flipping station. One end of the timber transverse arrangement mechanism is connected to the flipping mechanism, and the other end is connected to the fully automatic timber stacking machine. During operation, the flipping mechanism flips the longitudinally arranged timber group that has been conveyed to the flipping station of the conveying mechanism. The timber transverse arrangement mechanism arranges the longitudinally arranged timber group piece by piece and conveys it so that the timber is transversely arranged and enters the fully automatic timber stacking machine.

[0013] In the above scheme, the timber sorting device of the present invention sorts the timber sawn by the automatic log sawing device into longitudinally arranged timber groups, and then transports them laterally to the fully automatic timber stacking machine via a docking automatic timber conveying and distribution arrangement device. During operation, a flipping mechanism flips the longitudinally arranged timber groups conveyed by the timber sorting device to the conveying mechanism, and a timber lateral arrangement mechanism arranges each piece of the longitudinally arranged timber group on the flipping mechanism laterally, and then transports them to the fully automatic timber stacking machine. This not only connects the front and rear processes of timber processing into a complete fully automatic production line, reducing personnel requirements, but also significantly improves the production efficiency of the fully automatic timber stacking machine. Furthermore, when the fully automatic timber stacking machine removes the timber stacks, the present invention can use a conveying mechanism to transport the longitudinally arranged timber groups formed by the timber sorting device into a buffer silo for buffering, thereby maintaining continuous production.

[0014] The flipping mechanism includes a rotating shaft, several sets of flipping frames, and a rotating power component; the several sets of flipping frames are evenly arranged on the rotating shaft; the rotating power component is connected to the rotating shaft to drive the rotating shaft to rotate and drive the several sets of flipping frames to flip.

[0015] The conveying mechanism is a roller conveying mechanism; the turning station is the space between adjacent rollers; the turning frame extends into the turning station; adjacent groups of turning frames are perpendicular to each other; each group of turning frames includes at least two frames.

[0016] Each frame is a frame structure; the frame structure is provided with a square timber outlet; the frame is composed of two long side support rods and two short side support rods connected together; one long side support rod is connected to the rotating shaft, and the other long side support rod and the short side support rod near the rotating shaft are provided with a square timber outlet.

[0017] The transverse arrangement mechanism for square timber includes a frame, a conveyor chain, a transverse arrangement drive and transmission assembly, and several actuating components. The conveyor chain is mounted on the frame, and the transverse arrangement drive and transmission assembly is connected to the conveyor chain to drive its movement. Several actuating components are mounted on the conveyor chain, and when the conveyor chain moves, the actuating components move the square timbers on the flipping mechanism piece by piece onto the conveyor chain.

[0018] The space in the middle of the frame serves as the space for the flipping mechanism to flip; several actuating components are arranged on the conveyor chain, and the space between adjacent actuating components serves as the space for placing square timber.

[0019] The transverse arrangement mechanism of the square timber also includes an adjusting cylinder for adjusting the height of the end of the frame; the drive part of the adjusting cylinder is connected to the frame.

[0020] The timber sorting device includes a sorting frame, an adjustable tilting angle conveying platform, a sorting mold, and a positioning module for positioning the sorting mold; the conveying platform is set on the sorting frame and connected to the automatic log sawing device; the sorting mold is set on the conveying platform, and the positioning module is installed on the side of the conveying platform and can be extended and retracted to press and position the sorting mold on the conveying platform; the sorting mold is provided with a sorting inlet.

[0021] The buffer silo includes a silo frame, several layers of cantilever frames for placing longitudinally arranged square timber assemblies, a first transmission chain and a second transmission chain for driving the cantilever frames, and a chain drive component for driving the first transmission chain and the second transmission chain. The first transmission chain and the second transmission chain are arranged in parallel, and each layer of cantilever frame is connected to the first transmission chain and the second transmission chain respectively. The chain drive component is set on the silo frame and drives the first transmission chain and the second transmission chain to rotate synchronously on opposite sides of the silo frame, thereby realizing the movement of the cantilever frames.

[0022] Each cantilever frame includes a crossbeam and several cantilever arms; the crossbeam is connected to drive chain one and drive chain two respectively, and the several cantilever arms are perpendicularly connected to the crossbeam; each cantilever arm is provided with a limiting strip for limiting the longitudinal arrangement of square timber groups.

[0023] The automatic log sawing device includes a multi-axis multi-blade saw main unit, a sliding table base, and a rotatable base. The multi-axis multi-blade saw main unit is opposite to the timber handling device, and the sliding table base is located on the side of the multi-axis multi-blade saw main unit. The rotatable base is slidably connected to the sliding table base. The rotatable base is provided with a mounting plate, and both sides of the mounting plate are provided with shafts for mounting saw blades. After the rotatable base rotates, the shafts on the mounting plate facing the multi-axis multi-blade saw main unit are concentrically aligned with the saw shaft of the multi-axis multi-blade saw main unit.

[0024] The shafts on each side of the mounting plate are axially symmetrical about the rotation axis of the rotatable base; the shafts on the same side are axially symmetrical about the rotation axis of the rotatable base and diagonally distributed; the shafts on two sides are staggered and located at the four apex corners of the mounting plate.

[0025] This invention allows a rotatable base to be driven by a sliding base to approach the multi-axis multi-blade panel saw host. Since the shafts on both sides of the rotating mounting plate of the rotatable base are concentric with the saw shaft of the multi-axis multi-blade panel saw host, the old and new saw blades can be loaded and unloaded at one time and replaced synchronously by controlling the rotation of the rotatable base. This can significantly shorten the saw blade replacement time of the multi-axis multi-blade panel saw, not only reducing labor intensity but also improving the work efficiency of log sawing and cutting.

[0026] The working process of the automatic timber palletizing and conveying equipment of this invention is as follows:

[0027] (1) The multi-axis, multi-blade saw of the automatic log sawing device saws the logs.

[0028] (2) Adjust the tilt angle of the conveying platform. The positioning module of the timber sorting device positions the sorting mold at the low end of the conveying platform, so that the timber after being sawn by the automatic log sawing device enters the sorting mold through the conveying platform for longitudinal arrangement, forming a longitudinally arranged timber group.

[0029] (3) Remove the material handling mold, and the longitudinally arranged square timber group is conveyed to the conveying mechanism of the automatic square timber conveying and distribution device via the conveying platform. Control the conveying mechanism to convey the longitudinally arranged square timber group to the turning frame at the turning station, and control the rotating power component to drive the turning frame to turn 90°. At this time, the square timber is longitudinally stacked on the turning frame. The actuating parts on the transverse square timber arrangement mechanism, which move with the conveying chain, move the square timber on the turning frame piece by piece from the square timber outlet to the conveying chain, so that the square timber is transversely arranged on the conveying chain between adjacent actuating parts, realizing the arrangement and conveying of square timber from the automatic log sawing device to the fully automatic square timber stacking machine.

[0030] As the fully automatic timber stacking machine removes timber stacks, the conveying mechanism transports the longitudinally arranged timber groups formed by the timber sorting device into the buffer hopper via a cantilever frame connected to the conveying mechanism. The chain drive unit drives transmission chains one and two, causing the cantilever frame to rise or fall to replace the longitudinally arranged timber groups transported by the conveying mechanism, thus achieving buffering. Once the fully automatic timber stacking machine has completed the removal and is re-stacking, the program reverses the above actions, releasing the timbers one by one to maintain continuous production on the entire line.

[0031] When the saw blades of the multi-axis multi-blade saw of the automatic log sawing device need to be replaced, the rotatable base can be driven by the sliding table base to approach the multi-axis multi-blade saw, and the rotation of the rotatable base can be controlled to realize the simultaneous loading and unloading of the old saw blades and the new saw blades.

[0032] Compared with the prior art, the present invention has the following advantages and beneficial effects: The material preparation and conveying equipment for automatic timber stacking of the present invention can realize log sawing, automatic buffering of sawn timber, and automatic arrangement and conveying by docking with fully automatic timber stacking machine. It can not only connect the timber sawing process and the stacking process into a complete fully automatic production line, reducing personnel configuration, but also significantly improve the production efficiency of fully automatic timber stacking machine.

Furthermore, the shafts 9.2 on two sides are staggered, located at the four apex corners of the mounting plate 9.10.

[0060] The working process of the automatic timber palletizing and conveying equipment of this invention is as follows:

[0061] (1) Adjust the tilt angle of the conveying platform 7.2, and the positioning module 7.4 of the timber sorting device 7 positions the sorting mold 7.3 on the lower end of the conveying platform 7.2, so that the timber 4 after being sawn by the automatic log sawing device 9 enters the sorting mold 7.3 through the conveying platform 7.2 for longitudinal arrangement, forming a longitudinally arranged timber group 6.

[0062] (2) The material handling mold 7.3 is removed, and the longitudinally arranged square timber group 6 is conveyed to the conveying mechanism 1 of the automatic square timber conveying and distributing device via the conveying platform 7.2. The conveying mechanism 1 is controlled to convey the longitudinally arranged square timber group 6 to the flipping frame 2.2 of the flipping station 5, and the rotating power component 2.3 is controlled to drive the flipping frame 2.2 to flip to 90°. At this time, the square timber 4 is longitudinally stacked on the flipping frame 2.2. The actuating component 3.3 on the square timber transverse arrangement mechanism 3 moves with the conveying chain 3.2 to move the square timber 4 on the flipping frame 2.2 piece by piece from the square timber discharge port 2.4 to the conveying chain 3.2, so that the square timber 4 is transversely arranged on the conveying chain 3.2 between adjacent actuating components 3.3, realizing the arrangement and conveying of the square timber 4 from the automatic log sawing device 9 to the fully automatic square timber stacking machine 10.

[0063] (3) During the removal of the timber stack by the fully automatic timber stacking machine 10, the conveying mechanism 1 transports the longitudinally arranged timber group 6 formed by the timber sorting device 7 into the buffer bin 8. The cantilever 8.2, which is connected to the conveying mechanism 1, is then connected to the buffer bin 8. The chain drive component 8.5 drives the transmission chain 1 8.3 and the transmission chain 2 8.4 to move, causing the cantilever 8.2 to rise or fall to replace the longitudinally arranged timber group 6 transported by the conveying mechanism 1, thus achieving buffering. After the fully automatic timber stacking machine 10 completes the removal and re-stacking, the program drives the above actions in reverse, releasing the timber 4 grid by grid to maintain continuous production of the entire production line.

[0064] The multi-axis, multi-blade panel saw of the automatic log sawing device 9 and the fully automatic timber stacking machine 10 in this embodiment are both commonly used equipment in wood processing and are existing technologies.

[0065] When the multi-shaft, multi-blade saw of the automatic log sawing device needs to replace the saw blades, the quick-change process for the multi-blade saw is as follows:

[0066] (1) See Figure 7 The new saw blade 9.3 is installed on the shaft 9.2 on the first side of the mounting plate 9.10 through the shaft hole sleeve. The control slide drive mechanism drives the rotatable base 9.1 on the slide 9.7 to move towards the multi-axis multi-blade panel saw host 9.4, so that the shaft 9.2 on the second side of the mounting plate 9.10 is connected to the saw shaft 9.4.1 of the multi-axis multi-blade panel saw host 9.4.

[0067] (2) See Figure 8The old saw blade 9.6 on the saw shaft 9.4.1 of the multi-axis multi-blade panel saw host 9.4 is slid back onto the shaft 9.2 on the second side of the mounting plate 9.10.

[0068] (3) See Figure 9 The control slide drive mechanism drives the rotatable base 9.1 on the slide 9.7 to move backward, and the control rotation drive mechanism drives the rotatable base 9.1 to rotate 180°, so that the shaft 9.2 on the first side of the mounting plate 9.10 is aligned with the multi-axis multi-blade panel saw host 9.4.

[0069] (4) See Figure 10 The control slide drive mechanism drives the rotatable base 9.1 on the slide 9.7 to move towards the multi-axis multi-blade panel saw host 9.4, so that the shaft 9.2 on the first side of the mounting plate 9.10 is connected to the saw shaft 9.4.1 of the multi-axis multi-blade panel saw host 9.4.

[0070] (5) See Figure 11 The new saw blade 9.3, which is mounted on the shaft 9.2 on the first side of the mounting plate 9.10, is pushed and slid onto the saw shaft 9.4.1 of the multi-axis multi-blade panel saw host 9.4.

[0071] (6) See Figure 12 The control slide drive mechanism drives the rotatable base 9.1 on the slide 9.7 to move backward, the multi-axis multi-blade panel saw host 9.4 restarts to work, and the old saw blade 9.6 on the shaft 9.2 on the second side of the mounting plate 9.10 is recycled.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
