Description

Technical Field

[0001] This utility model relates to the field of sawn timber testing technology, specifically to a sawn timber transport device for chainsaw testing equipment. Background Technology

[0002] In the fields of chainsaw research and development, performance testing, and quality control, it is crucial to conduct objective and repeatable evaluations of key performance indicators such as sawing efficiency and fuel consumption. Such tests typically require repeated cutting of standardized test lumber (such as round pine or round fir wood of specific sizes and materials) on a dedicated test bench. To achieve repeated sawing, relative movement between the lumber and the chainsaw is necessary. Since no wiring is required on the lumber, it is generally fed towards the chainsaw, allowing the chainsaw to cut the lumber.

[0003] In existing technologies, feeding mainly relies on manual feeding or simple mechanical feeding. Both methods suffer from low automation, high safety risks, and low testing efficiency. Specifically: Manual feeding: Operators hold or use a pusher to push the sawn timber toward the chainsaw. The distance between the operator's hand and the chainsaw is close, posing a safety hazard and easily causing accidents. The feeding rhythm depends entirely on the worker's experience and physical strength, making it impossible to achieve uniform and continuous feeding. During the testing process, the worker's physical strength will decline, resulting in a decrease in feeding speed and affecting testing efficiency. Simple mechanical auxiliary feeding: The push plate is driven by a cylinder or motor, which can only achieve a single pushing action and has a low degree of automation. During the reset process after completing a sawing, the chainsaw may interfere with the sawn material, affecting the equipment life and testing safety.

[0004] Therefore, there is a need for a sawn timber transport device that is highly automated, safe, and efficient in testing. Utility Model Content

[0037] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] The sawn timber conveying device for chainsaw testing equipment disclosed in this application can be applied to occasions such as when chainsaw performance testing equipment needs to convey sawn timber, and of course it can also be used in other similar application scenarios. The following is a detailed description of the sawn timber conveying device for chainsaw testing equipment.

[0039] Example 1 See appendix Figure 1 — Figure 7 The diagram shows a preferred embodiment of a sawn timber conveying device for a chainsaw testing equipment according to this application. The sawn timber conveying device for the chainsaw testing equipment includes a frame 100 with multiple workstations. Each workstation is equipped with a conveying assembly 200, a first clamping assembly 300 mounted on the frame 100, and a monitoring structure 400 for monitoring the remaining sawn timber.

[0040] This application provides installation space for the conveying assembly 200, the first clamping assembly 300, and the monitoring structure 400 through the frame 100. The conveying assembly 200 enables automatic conveying of sawn timber. During the entire conveying process, operators do not need to contact the sawn timber, achieving automated feeding and conveying, reducing labor intensity, ensuring operator safety, and allowing the sawn timber to retract, preventing interference between the chainsaw and the timber during resetting and ensuring normal performance testing. The first clamping assembly 300 applies pressure to the sawn timber, clamping it in conjunction with the support provided by the conveying assembly 200, preventing the sawn timber from moving arbitrarily or shifting on the conveying assembly 200. The monitoring structure 400 monitors the remaining amount of sawn timber, ensuring that the first clamping assembly 300 can clamp the sawn timber after movement, preventing it from warping. It should be noted that the frame 100 is also equipped with a controller for the conveying assembly 200, the first clamping assembly 300 and the monitoring structure 400. This controller can be a PLC controller with a touch screen.

[0041] See appendix Figure 1 — Figure 4 As shown in this application, the frame 100 is provided with a plurality of mounting plates 110, the number of which is equal to the number of conveying components 200; the mounting plates 110 provide installation conditions for the conveying components 200, and the number of which is equal to the number of workstations in the frame 100.

[0042] See appendix Figure 5 As shown in this application, the conveying assembly 200 includes a conveying power source 210, several sets of mounting seats 220 mounted on the mounting plate 110, a conveying component 230 movably mounted on the mounting seat 220, and a first transmission structure 240 disposed on the conveying power source 210 and one of the conveying components 230.

[0043] This application uses a power source 210 to drive the conveyor component 230 to rotate. The power source 210 can be a stepper motor or a servo motor. The mounting base 220 is used to support both ends of the conveyor component 230 and is movably connected to both ends of the conveyor component 230. The first transmission structure 240 is used to transmit the power from the power source 210 to the conveyor component 230, so that the conveyor component 230 can rotate.

[0044] See appendix Figure 5 As shown, in this application, the first transmission structure 240 includes a driving member 241 mounted on the conveying power source 210, a driven member 242 mounted on the end of the conveying member 230, and a first connecting member 243 fitted onto the driving member 241 and the driven member 242. It should be noted that the driving member 241 and the driven member 242 can both be sprockets, in which case the first connecting member 243 is a chain; or the driving member 241 and the driven member 242 can be pulleys, in which case the first connecting member 243 is a transmission belt. In this application, the conveying power source 210 drives the driving member 241 to rotate, the driving member 241 drives the first connecting member 243 to rotate, the first connecting member 243 drives the driven member 242 to rotate, and the driven member 242 drives the conveying member 230 to start rotating, thereby driving the sawn timber to feed and move through friction.

[0045] See appendix Figure 5 As shown in this application, when the number of mounting bases 220 is not less than two, the conveying member 230 is provided with a second transmission structure 250; wherein, the second transmission structure 250 includes a power receiving member 251, a power output member 252, and a second connecting member 253 for connecting the power receiving member 251 and the power output member 252 on different conveying members 230; it should be noted that the end of the conveying member 230 is equipped with a power receiving member 251 and / or a power output member 252.

[0046] This application, through the setting of the second transmission structure 250, can transmit power between the conveying components 230, so that all the conveying components 230 can rotate to convey the sawn timber; through the setting of the power receiving component 251 and the power output component 252, in conjunction with the second connecting component 253, power can be transmitted; it should be noted that when the conveying component 230 only needs to receive the power transmitted from other conveying components 230, only the power receiving component 251 needs to be set; when it needs to receive the power transmitted from other conveying components 230 and also needs to transmit power to other conveying components 230, only the power receiving component 251 and the power output component 252 need to be set; when it only needs to output power to other conveying components 230, only the power output component 252 needs to be set, and the power input is through the first transmission structure 240. It should be noted that both the power receiving component 251 and the power output component 252 can be sprockets, in which case the second connecting component 253 can be a chain; or both the power receiving component 251 and the power output component 252 can be pulleys, in which case the second connecting component 253 can be a transmission belt.

[0047] See appendix Figure 6 and Figure 7 As shown in this application, the conveying component 230 includes a rotating shaft 231 movably mounted on the mounting base 220, and a limiting roller 232 or a spiked roller 233 disposed on the rotating shaft 231. It should be noted that the rotating shaft 231 is provided with a limiting hole, in which a limiting component is installed. The limiting component can be a detachable pin, stud, bolt, etc., used to prevent the conveying component 230 from moving in the axial direction and to prevent the conveying component 230 from separating from the mounting base 220. The limiting roller 232 is provided with a limiting groove, which limits the sawn wood and keeps it at the lowest position of the limiting groove. At least one of the rotating shafts 231 of the conveying component 230 is provided with a spiked roller 233. The rotation of the spiked roller 233 can pierce the sawn wood to prevent the sawn wood from slipping.

[0048] See appendix Figure 2 and Figure 3As shown, in this application, the first clamping assembly 300 includes a clamping power source 310 mounted on the frame 100 and a clamping block 320 mounted on the clamping power source 310. The clamping power source 310 drives the clamping block 320 to move vertically, allowing for the compression of sawn timber of different diameters. Combined with the conveying assembly 200, this clamps the sawn timber, preventing it from warping during sawing. The clamping block 320 holds the sawn timber in place; when the clamping power source 310 lowers the clamping block 320, it clamps the sawn timber. It should be noted that the clamping block 320 may have an arc-shaped groove to accommodate the diameter of the sawn timber. It should also be noted that the clamping power source 310 is a telescopic cylinder or a telescopic electric cylinder, and the clamping block 320 is made of a soft material or has a surface covered with a soft material, such as rubber.

[0049] See appendix Figure 3 As shown, in this application, the monitoring structure 400 includes a mounting block 410 mounted on the frame 100 or the lifting power source, and a sensor 420 mounted on the mounting block 410. The monitoring point of the sensor 420 on the sawn timber is located on the same side of the frame 100 as the clamping block 320. The sensor 420 illuminates the surface of the sawn timber to form a monitoring point. The cross-section of the sawn timber passing through the monitoring point is a first plane. The center point of contact between the clamping block 320 and the sawn timber is a clamping point. The cross-section of the sawn timber passing through the clamping point is a second plane. The first plane is located upstream of the second plane, and the distance between the first plane and the second plane is less than the distance that the conveying assembly 200 conveys the sawn timber in a single operation.

[0050] This application provides installation conditions for the sensor 420 by setting the mounting block 410. The mounting block 410 can be provided with an inclined surface to adjust the installation angle of the sensor 420. By setting the sensor 420, the remaining amount of sawn timber is monitored to ensure that the clamping block 320 can clamp the sawn timber. By setting the relative positions of the monitoring point and the clamping point, it is ensured that the sawn timber passes through the monitoring point first and then the clamping point during emergency transport. When the monitoring point does not sense the sawn timber, it indicates that there is a risk at the clamping point and that the clamping block 320 may not be able to clamp the sawn timber.

[0051] See appendix Figure 1 — Figure 7 As shown, the usage process of this application is as follows: First, the worker starts the conveyor assembly 200 via the controller. Then, the worker moves the sawn timber onto the conveyor assembly 200, which feeds the timber to the designated position. Specifically, the worker starts the conveyor power source 210 via the controller. The power source 210 drives the driving component 241 to rotate via a spline. The driving component 241 drives the driven component 242 to rotate via the first connecting component 243. The driven component 242 drives the connected conveyor component 230 to rotate via a spline. The conveyor component 230 drives the connected power output component 252 to rotate via a spline. Part 252 drives the power receiving part 251 to start rotating through the second connecting part 253, thereby driving the next conveying part 230 to rotate. This process is repeated until all the conveying parts 230 start rotating. Then, the worker moves the sawn timber onto the conveying assembly 200, placing one end of the sawn timber on the conveying part 230 of the conveying assembly 200. With the worker's assistance, the sawn timber is fed onto the conveying assembly 200 until the sensor 420 senses the sawn timber and sends a signal to the controller. The controller controls the sawn timber to rotate a number of times or at a certain angle according to the received signal, so that the sawn timber moves forward a specified distance, completing the feeding of the sawn timber. In the second step, the operator controls the conveying assembly 200 to start conveying the sawn timber via the controller. The controller also starts the conveying power source 210 and rotates it a specified number of times. Through the cooperation of the first transmission structure 240 and the second transmission structure 250, all the conveying components 230 begin to rotate, allowing the sawn timber to advance a specified distance. Subsequently, the controller starts the clamping power source 310 in the first clamping assembly 300. The clamping power source 310 drives the clamping block 320 to descend, applying pressure to the sawn timber to clamp it and ensure that the sawn timber does not warp during the chainsaw cutting process. After sawing is completed, the operator controls the first clamping assembly 300 to reset via the controller and controls the conveying power source 210 to rotate in the opposite direction, causing the sawn timber to retract a specified distance to avoid the chainsaw's reset and prepare for the next chainsaw cut. This step is repeated until the controller receives a signal from the sensor 420, and the controller screen displays an alarm message, reminding the operator to load the sawn timber.

[0052] Example 2 See appendix Figure 8 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the clamping block 320 is provided with a mounting groove 321, and a clamping wheel 322 is movably mounted in the mounting groove 321 by a pin; wherein, there are two clamping wheels 322, and any point on the center line of the sawn wood in contact with the clamping wheel 322 is equidistant from the two clamping wheels 322.

[0053] In this embodiment, the mounting groove 321 provides installation space for the clamping wheel 322. The clamping wheel 322, along with its movable connection, allows it to rotate within the mounting groove 321. Therefore, when clamping the sawn timber to prevent it from warping, the clamping wheel 322 does not affect the timber's transport. Each time the sawn timber is transported, the clamping power source 310 does not need to lift the clamping wheel 322, further improving transport efficiency. Furthermore, by controlling the number of clamping wheels 322 and ensuring that the distance from any point on the sawn timber's centerline to any two clamping wheels 322 is equal, the symmetrical arrangement of the clamping wheels 322 effectively prevents the sawn timber from shifting.

[0054] Example 3 See appendix Figure 9 and Figure 10 As shown, the difference between this embodiment and the above embodiment is that, in this embodiment, the number of second clamping assemblies 500 installed on the frame 100 is not less than the number of workstations set on the frame 100; wherein, the second clamping assembly 500 includes a limiting clamping plate 510 installed on the frame 100, a connecting post 520 passing through the limiting clamping plate 510, a limiting wheel 530 movably installed on the connecting post 520 and in contact with the sawn wood, and a limiting wheel 530 installed on the connecting post 520. Part 540; It should be noted that the limiting wheel 530 is horizontally set and contacts the outer wall of the sawn timber. The limiting wheel 530 rotates when the sawn timber is fed or retracted; the moving direction of the connecting column 520 on the limiting clamping plate 510 is perpendicular to the moving direction of the sawn timber on the conveying assembly 200; the connecting column 520 is a screw, the limiting part 540 is a nut, and the limiting clamping plate 510 is provided with a waist-shaped hole corresponding to the connecting column 520; the size of the limiting part 540 is larger than the size of the waist-shaped hole.

[0055] In this embodiment, the limiting clamping plate 510 provides an installation position for the connecting column 520; the connecting column 520 provides an installation position for the limiting wheel 530; and the upper limit member 540, in conjunction with the upper limit member 540, allows for adjustment of the connecting column 520, which can be adjusted according to the diameter of the sawn timber; the limiting member 540 restricts the position of the limiting wheel 530; and the limiting wheel 530 fixes the sawn timber radially, preventing radial movement of the sawn timber during movement.

[0056] Example 4 See appendix Figure 11 and Figure 12As shown, the difference between this embodiment and the above embodiment is that in this embodiment, a sliding support assembly 600 is also installed on the frame 100. The sliding support assembly 600 includes a slide rail 610 installed on the mounting plate 110, a slider 620 slidably installed on the slide rail 610, and a sliding support plate 630 installed on the slider 620. The sliding support plate 630 is provided with an arc-shaped groove 640.

[0057] In this embodiment, the sliding support plate 630 is used to guide the movement of the slide rail 610 and the slider 620. The sliding support plate 630 is used to support the sawn timber, and the arc-shaped groove 640 is used to radially guide and limit the sawn timber. This embodiment uses a sliding support to reduce the number of conveyor components 230 and mounting base 220, thereby reducing costs.

[0058] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
