Description

[0001] The present application is a divisional application of the patent application No. 202211583305.0, with the application date of December 9, 2022, and the name of "Bamboo sawing method", which is the parent application. TECHNICAL FIELD

[0002] The present application relates to the technical field of bamboo processing, in particular to a method for sawing raw bamboo. BACKGROUND

[0003] The patent No. CN217256867U discloses a conveying mechanism for sawing raw bamboo, which utilizes the first clamping assembly to roll and clamp the outer circumferential surface of the raw bamboo, and utilizes the linear motion mechanism of the second clamping assembly to drive the clamping piece to clamp one end of the raw bamboo and pull it out in the conveying direction. After being pulled out to the fixed length point, the raw bamboo is sawed by the sawing device. After sawing, the clamping piece of the second clamping assembly is loosened, so that the fixed-length sawed raw bamboo naturally falls and is collected.

[0004] In the above-mentioned patent solution, the second clamping assembly needs to be movably connected to the linear motion mechanism (such as a lead screw guide rail mechanism). Since the second clamping assembly moves along the linear motion mechanism to pull the raw bamboo out of the fixed length point and to saw it at a fixed length, the second clamping assembly needs to be returned to its original position, and then the next section of raw bamboo needs to be pulled out to the fixed length point and sawed at a fixed length. This process is repeated.

[0005] Therefore, in the above-mentioned patent solution, the return of the second clamping assembly wastes a small amount of time. That is, after each sawing of the raw bamboo, the raw bamboo needs to be stopped for a short period of time before it can be conveyed forward. If this small amount of time can be saved, the work efficiency can be improved when a large amount of raw bamboo is sawed.

[0006] Therefore, how to ensure accurate fixed-length cutting of raw bamboo and improve the work efficiency of fixed-length cutting has become a technical problem to be solved. SUMMARY

[0007] The technical problem to be solved by the present application is how to ensure accurate fixed-length cutting of raw bamboo and improve the work efficiency of fixed-length cutting.

[0008] In order to solve the above technical problem, the technical solution adopted by the present application is as follows:

[0009] A method for sawing bamboo, comprising the following steps:

[0010] Conveying the raw bamboo to be sawed forward along its axial direction at a preset speed;

[0011] The front end of the raw bamboo abuts against the buffer material blocking piece, and the buffer material blocking piece is pushed to move forward at a deceleration and stops at a first position;

[0012] The control buffer stopper moves forward to the second position and separates from the front end of the raw bamboo;

[0013] The raw bamboo is sawed to form bamboo segments.

[0014] The present application has the beneficial effect that in the raw bamboo conveying mode, the continuous conveying mode is used to replace the original reciprocating conveying mode of the linear motion mechanism, the required time for the linear motion mechanism to return is saved, the interval stay time of the raw bamboo length cutting is reduced, the work efficiency is improved, the raw bamboo front end is buffered by the buffer stopper, then the conveying is controlled to stop, the raw bamboo is conveyed to the cutting point, the conveying is slowed down and buffered first, then accurately stopped, and the accuracy of the raw bamboo cutting point is ensured.

[0028] In order to describe the technical content, the achieved purposes and effects of the present application in detail, the following will be described in combination with the embodiments and the drawings.

[0029] Reference will now be made to Figures 1 to 3 The embodiment of the present application relates to a bamboo sawing method, comprising the following steps:

[0030] The original bamboo to be sawed is conveyed forward along its axial direction at a preset speed;

[0031] The front end of the original bamboo abuts against the buffer stopper 31 and pushes the buffer stopper 31 to move forward at a reduced speed and stop at a first position;

[0032] The buffer stopper 31 is controlled to move forward to a second position and separate from the front end of the original bamboo;

[0033] The original bamboo is sawed to form a bamboo segment.

[0034] As an optional embodiment, the bamboo sawing method is based on a bamboo sawing device, which comprises a clamping and conveying member 1, a sawing mechanism 2 and a positioning mechanism 3 arranged in sequence along the conveying direction of the original bamboo:

[0035] The clamping and conveying member 1 is used to clamp the outer circumferential surface of the original bamboo and drive the original bamboo to convey along the conveying direction;

[0036] The sawing mechanism 2 is used to cut the original bamboo;

[0037] The positioning mechanism 3 comprises a buffer stopper 31, a sliding seat 32, a driving member, an elastic member and a fixing frame 35, the buffer stopper 31 is movably connected to the sliding seat 32 through the elastic member, the sliding seat 32 is movably connected to the fixing frame 35, and the driving member is used to drive the sliding seat 32 to slide relative to the fixing frame 35;

[0038] The buffer stopper 31 has a first position for buffering and positioning the original bamboo and a second position for separating from the original bamboo;

[0039] In the first position, the buffer stopper 31 has a first state of contacting the original bamboo and compressing the elastic member 34;

[0040] In the second position, the buffer stopper 31 has a second state of separating from the original bamboo and resetting the elastic member 34;

[0041] The bamboo sawing method comprises the following steps:

[0042] S11: The clamping and conveying member 1 clamps the outer circumferential surface of the original bamboo and conveys the original bamboo forward along its axial direction at a preset speed;

[0043] S12: The front end of the original bamboo abuts against the buffer stopper 31 and pushes the buffer stopper 31 to move forward at a reduced speed and stop at a first position;

[0044] S13: The driving member drives the sliding seat 32 to move, drives the buffer material blocking member 31 to move forward to the second position and separates from the front end of the raw bamboo;

[0045] S14: The sawing mechanism 2 cuts the raw bamboo to form bamboo segments.

[0046] In the above embodiment, the positions of the first position and the second position can be adjusted adaptively according to the length of the bamboo segment obtained by cutting the raw bamboo at the actual length, so as to meet the length cutting requirement of the bamboo segment of different lengths. In practical application, there can be various schemes to realize the above functions, for example, by adjusting the initial position of the sliding seat 32 connected on the second guide rail 351, or directly adjusting the position of the fixed frame 35, or any other mechanism that can realize the above functions. Herein, no specific limitation is made.

[0047] In the above embodiment, the clamping and conveying member 1 can be a conveying belt, a conveying roller or any other mechanism that can clamp the outer circumferential surface of the raw bamboo and move the raw bamboo in the conveying direction by the friction force on the surface of the clamping and conveying member 1. The buffer material blocking member 31 can include a material blocking plate and a sliding block. The material blocking plate is fixedly connected to the sliding block. The sliding seat 32 is provided with a first guide rail parallel to the conveying direction. The sliding block is in sliding connection with the first guide rail. The elastic member is a spring. The elastic direction of the spring is parallel to the conveying direction. One end of the spring is connected to the sliding block, and the other end is connected to the sliding seat 32. In order to limit the elastic direction of the spring, a guide column can also be arranged at the center of the spring. The upper portion of the fixed frame 35 is provided with a second guide rail 351 parallel to the conveying direction. The sliding seat 32 is in sliding connection with the second guide rail 351. The driving member 33 can be a pneumatic cylinder, a hydraulic cylinder or an electric push rod. One end of the driving member 33 is connected to the fixed frame 35, and the other end is connected to the sliding seat 32. The driving member is used to drive the sliding seat 32 to move along the second guide rail 351.

[0048] The working principle of the above embodiment is as follows. The clamping and conveying member 1 clamps the outer circumferential surface of the raw bamboo, and drives the raw bamboo to move in the conveying direction by the friction force between the clamping and conveying member 1 and the raw bamboo. Until the end of the raw bamboo contacts the buffer material blocking member 31 and pushes the material blocking member to move in the conveying direction along the first guide rail, the elastic member is compressed, and the material blocking member moves a predetermined stroke. Then, the clamping and conveying member 1 stops conveying the raw bamboo. The driving member drives the sliding seat 32 to move in the conveying direction along the second guide rail 351, so that the buffer material blocking member 31 is separated from the end of the raw bamboo. At this time, the buffer material blocking member 31 is returned to the original position in the reverse direction of the conveying direction under the action of the elastic member. The sawing mechanism 2 cuts the raw bamboo. The cut bamboo segment falls and is collected between the sawing mechanism 2 and the positioning mechanism 3, or is conveyed to the side by the conveying mechanism and is collected. At this time, the driving member drives the sliding seat 32 to move in the reverse direction of the conveying direction along the second guide rail 351 to return to the initial position. The above process is repeated.

[0049] In the above embodiment, the outer circumferential surface of the raw bamboo is clamped by the clamping conveying member 1, and the raw bamboo is conveyed axially along the conveying direction by the movable belt of the clamping conveying member 1. The specific positional relationship of the buffer material blocking member 31, the movable seat and the fixed frame 35 is matched, so that the raw bamboo is first buffered and decelerated by the elastic member when being conveyed to the fixed length, and is stopped at the fixed length position. At this time, the sawing point of the raw bamboo is accurately positioned at the position of the sawing mechanism 2. The buffer material blocking member 31 is driven by the driving member to be separated from the end of the raw bamboo, and the raw bamboo is cut by the sawing mechanism 2. The above-mentioned structure is repeatedly circulated to achieve the fixed-length cutting of the whole raw bamboo. The action of driving the buffer material blocking member 31 to be separated from the end of the raw bamboo by the driving member avoids the backward movement of the raw bamboo caused by the rebounding force of the elastic member, thereby ensuring the flatness of the bamboo section. In the above structure, the clamping conveying member 1 is used to replace the original linear motion mechanism, which saves the required time for the backward movement of the linear motion mechanism, reduces the interval residence time of the fixed-length cutting of the raw bamboo, and improves the work efficiency. By using the specific structure of the positioning mechanism 3, the raw bamboo can be first decelerated and buffered, and then accurately stopped when being conveyed to the cutting point position, thereby ensuring the accuracy of the cutting point position of the raw bamboo.

[0050] As an optional embodiment, the bamboo sawing device further comprises a controller and a sensor 4 connected to the sliding seat 32 for sensing the position of the buffer material blocking member 31.

[0051] The controller is electrically connected with the sensor 4, the sawing mechanism 2, the clamping conveying member 1 and the driving member respectively.

[0052] The bamboo sawing method specifically comprises the following steps:

[0053] S21: The controller controls the clamping conveying member 1 to clamp the outer circumferential surface of the raw bamboo and convey the raw bamboo axially along the raw bamboo at a preset speed;

[0054] S22: The front end of the raw bamboo abuts against the buffer material blocking member 31, pushes the buffer material blocking member 31 to move forward and decelerate and stops at the first position. The sensor 4 receives the sensing information and sends it to the controller. The controller controls the clamping conveying member 1 to stop conveying the raw bamboo.

[0055] S23: The controller controls the driving member to drive the sliding seat 32 to move, drives the buffer material blocking member 31 to move to the second position and separate from the front end of the raw bamboo, and resets the elastic member 34.

[0056] S24: The controller controls the sawing mechanism 2 to cut the raw bamboo to form a bamboo section.

[0057] In the above embodiments, the sensor 4 can have various forms, and any sensor 4 type that can generate an induction signal after the buffer stopper 31 moves to a specific stroke can be used in the present application. As a preferred embodiment, the sensor 4 is a proximity switch, i.e., the transmitting end 41 of the proximity switch is arranged on the movable seat, and the receiving end 42 of the proximity switch is arranged on the buffer stopper 31. When the buffer stopper 31 moves to a specific stroke, the light signal emitted by the transmitting end 41 of the proximity switch is received by the receiving end 42, generating an induction signal. The controller receives the induction signal and controls the clamping conveyor 1 to stop conveying the raw bamboo according to a preset program, controls the movable seat to move by the driving member, and controls the sawing mechanism 2 to cut the raw bamboo to a fixed length, and then controls the clamping conveyor 1 to continue conveying the raw bamboo in the conveying direction. The controller can be a PLC or a single-chip microcomputer, and the PLC is preferred.

[0058] As an optional embodiment, the bamboo sawing device further comprises a discharging mechanism 8 arranged between the sawing mechanism 2 and the positioning mechanism 3.

[0060] S15: The bamboo segment falls to the discharging mechanism 8, and the discharging mechanism 8 conveys the bamboo segment in a direction perpendicular to the conveying direction.

[0061] In the above embodiments, the discharging direction of the discharging mechanism 8 can be any side perpendicular to the conveying direction, i.e., the bamboo segment cut to a fixed length by the sawing mechanism 2 can be accumulated and collected on the left side or the right side of the mechanism by the conveying of the discharging mechanism 8. Compared with the direct discharging mode, the number of bamboo segments stored around the bamboo sawing device can be increased, thereby further improving the production efficiency.

[0062] As an optional embodiment, the discharging mechanism 8 comprises a platform 81 and a conveying chain 82 symmetrically arranged in the front-rear direction of the platform 81, the rotating direction of the chain is perpendicular to the conveying direction, and the chain is provided with a plurality of push rods 83 distributed at intervals. The discharging mechanism 8 further comprises a driving member for driving the chain to rotate forward or reversely.

[0063] In the above embodiments, the bamboo segment cut by the sawing mechanism 2 falls to the platform 81, the chain is driven to rotate by the driving member, the push rod 83 on the chain pushes the raw bamboo to one side of the conveying direction, and falls to one side of the discharging mechanism 8 for collection. Since the chain can rotate forward or reversely, the bamboo segment can be pushed to any side according to the space on both sides of the discharging mechanism 8.

[0064] As an optional embodiment, the bamboo sawing device further comprises a node detection device arranged behind the sawing mechanism 2 relative to the conveying direction, and the node detection device is electrically connected with the controller.

[0065] The sawing bamboo method, the S1 is specifically: the bamboo joint detection device detects whether the bamboo section cutting point position is a bamboo joint;

[0066] If it is detected that the bamboo section cutting point position is a bamboo joint, the controller controls the clamping conveying part 1 to clamp the outer circumferential surface of the original bamboo, drives the axial direction of the original bamboo to convey to the position 2-20 cm of the sawing mechanism 2 along the conveying direction by the friction between the clamping conveying part 1 and the original bamboo, controls the sawing mechanism 2 to cut off the part of the original bamboo extending out, controls the clamping conveying part 1 to clamp the outer circumferential surface of the original bamboo, and drives the forward conveying of the original bamboo to saw by the friction between the clamping conveying part 1 and the original bamboo.

[0067] If it is detected that the bamboo section cutting point position is not a bamboo joint, the controller controls the clamping conveying part 1 to clamp the outer circumferential surface of the original bamboo, and drives the forward conveying of the original bamboo to saw by the friction between the clamping conveying part 1 and the original bamboo.

[0068] As an optional implementation, the bamboo joint detection device is a visual detection device, and in the S1, the bamboo joint detection device detecting whether the bamboo section cutting point position is a bamboo joint specifically includes: the visual detection device acquires image information of the bamboo section cutting point position, judges whether the bamboo section cutting point position is a bamboo joint by analyzing corresponding pixel points of the image information.

[0070] As an optional implementation, the distance of the deceleration movement is 1-20 cm.

[0071] As an optional implementation, the bamboo sawing device further includes a bamboo joint detection device, the bamboo joint detection device is arranged at the rear of the sawing mechanism 2 relative to the conveying direction, and the bamboo joint detection device is electrically connected with the controller;

[0072] The sawing bamboo method, the S1 is specifically: the bamboo joint detection device detects whether the bamboo section cutting point position is a bamboo joint;

[0073] If it is detected that the bamboo section cutting point position is a bamboo joint, the controller controls the clamping conveying part 1 to clamp the outer circumferential surface of the original bamboo, drives the axial direction of the original bamboo to convey to the position 2-20 cm of the sawing mechanism 2 along the conveying direction by the friction between the clamping conveying part 1 and the original bamboo, controls the sawing mechanism 2 to cut off the part of the original bamboo extending out, controls the clamping conveying part 1 to clamp the outer circumferential surface of the original bamboo, and drives the forward conveying of the original bamboo to saw by the friction between the clamping conveying part 1 and the original bamboo.

[0074] If it is detected that the bamboo section cutting point position is not a bamboo joint, the controller controls the clamping conveying part 1 to clamp the outer circumferential surface of the original bamboo, and drives the forward conveying of the original bamboo to saw by the friction between the clamping conveying part 1 and the original bamboo.

[0075] As an optional embodiment, the bamboo sawing device further comprises a surplus sawing device 6, which is arranged behind the clamping and conveying member 1 relative to the conveying direction.

[0076] The bamboo sawing method further comprises the following steps: when the length of the raw bamboo is between 1 and 2 times the length of the bamboo section, when the clamping and conveying member 1 conveys the front end of the raw bamboo to a third position, the conveying is stopped, and the surplus sawing device 6 cuts the raw bamboo to a fixed length to form a bamboo section, and the distance between the third position and the sawing mechanism 2 is the length of the bamboo section minus the distance between the sawing mechanism 2 and the surplus sawing device 6.

[0077] In the above embodiment, the surplus sawing device 6 is used for fixed-length sawing of the last section of the raw bamboo. Assuming that the last section of the raw bamboo is cut off by the sawing mechanism 2, the conveying stability of the clamping and conveying member 1 will be greatly reduced, that is, the rear section of the raw bamboo cannot be fully supported, which will cause the raw bamboo to deviate during conveying, thereby making it difficult to ensure the flatness and accuracy of the cutting point. Since the last section of the raw bamboo is sawed by the surplus sawing device 6, the specific principle is that the distance between the surplus sawing device 6 and the sawing mechanism 2 is less than or equal to the length of the fixed-length bamboo section, that is, when the last section of the raw bamboo is cut to a fixed length, only a small section of the front end of the raw bamboo needs to extend beyond the clamping and conveying member 1, that is, the distance between the front end of the raw bamboo and the conveying direction of the sawing mechanism 2 plus the distance between the conveying direction of the sawing mechanism 2 and the surplus sawing device 6 is equal to the length of the fixed-length cut of the raw bamboo, which can ensure that the end of the raw bamboo is fully utilized.

[0086] As an optional embodiment, a supporting table 5 is further included, the supporting table 5 is used for supporting the bamboo.

[0087] In the above embodiment, the supporting table 5 is parallel to the horizontal plane, and is used for supporting the bamboo, so that the bamboo is conveyed in the horizontal direction, and the stability and precision of the bamboo conveying and length-cutting are further improved. As a preferred scheme, the axial direction of the rollers 11 is vertical.
