The controller and the computer are arranged in the control box, the controller is used for controlling the actions of all parts in the equipment, and the controller adopts a Mitsubishi FX3u-48M programmable controller.

As shown in fig. 2 and 3, the conveying mechanism includes a conveying frame, a conveying roller and a conveying power mechanism, and the conveying power mechanism includes a rubber wheel, a speed reduction motor and a second cylinder. The conveying frame is a square structure body, is used for providing support for the whole conveying mechanism and is divided into a top layer, a middle layer and a lower layer. The conveying frame is built by adopting square steel, is fixed by screw nuts through angle piece connecting pieces of 45 degrees, 90 degrees and 135 degrees, can be integrally disassembled, and is convenient to transport and improve in later period. The middle layer of the conveying frame is provided with 10 groups of conveying rollers, and the 10 groups of conveying rollers are transversely arranged to form a conveying roller bed for supporting the raw bamboos and simultaneously reducing the friction force when the raw bamboos are conveyed. The bottom of the conveying roller bed is provided with a third photoelectric sensor which can be used for detecting whether raw bamboo exists on the conveying roller bed. And a fourth photoelectric sensor is arranged at the discharge port of the conveying frame and used for detecting a first bamboo stump signal of the original bamboo.

The rubber wheels, the speed reducing motor and the second air cylinder are respectively three, a cross shaft is arranged in the middle of each rubber wheel and connected with the speed reducing motor through a plum blossom coupling, and two ends of each cross shaft are connected with the H-shaped structures. The top of the H-shaped structure is hung on the top layer of the conveying frame through the main shaft, the middle part of the H-shaped structure is connected with one end of a second air cylinder through a Y joint, and the other end of the second air cylinder is connected with the top layer of the conveying frame. The sizes of the three rubber wheels are 8 inches, 6 inches and 8 inches respectively, the cylinder diameters of the second air cylinders are 40mm, the stroke of one air cylinder is 200mm, and the strokes of the other two air cylinders are 150 mm. The speed reducing motor is a 25W motor. The expansion and contraction of the second air cylinder are controlled by the controller through the opening and closing of the magnet sensor, and the power source of all the air cylinders is provided by the air compressor. When the second cylinder contracts, the rubber wheel and the speed reducing motor start to ascend; when the second cylinder extends, the rubber wheel and the speed reducing motor start to descend to a certain degree and can press the original bamboo. The action principles of the three groups of rubber wheels and the second air cylinder are consistent and the actual command actions are synchronous, only one group of action conditions are described below, and three groups of actions are referred to in the actual operation.

When the whole equipment starts to operate, one end of the H-shaped structure starts to rise through the second air cylinder, enough space for placing is reserved for a conveying roller bed consisting of conveying rollers, and uncut raw bamboos are placed on the conveying roller bed. By default, the worker starts sawing from the bamboo stump in actual production, and the bamboo tip is the tail end of sawing. Therefore, when the original bamboo is placed, the bamboo stump is taken as the starting end of the sawing bamboo as the default, and the bamboo tip is taken as the tail end of the sawing bamboo, so that the second cutting of the fixed-length section into the small end can be guaranteed. After the raw bamboo is placed, the controller starts to read the signal change of the third photoelectric sensor below the conveying roller bed, if the signal change indicates that the roller bed has the raw bamboo, the controller controls the second cylinder to extend, and the rubber wheel starts to descend and press the raw bamboo. The third photoelectric sensor is used for generating a signal a in the case of no bamboo and a signal b in the case of bamboo, and the controller starts to control the rubber wheel to descend when detecting the signal b. After the rubber wheel descends to press the original bamboo, the speed reduction motor starts to run at a constant speed to drive the rubber wheel, the original bamboo is driven to move towards the sawing machine through friction, when the original bamboo moves to the fourth photoelectric sensor, the controller detects the signal change of the fourth sensor, timing is started, the speed reduction motor is allowed to run for a specific time, the specific rotating time is used for stopping the original bamboo after the original bamboo is conveyed for a certain distance, and then the controller controls the sawing machine to cut off the root of the bamboo stump to obtain a smooth fixed-length section tangent plane.

As shown in fig. 4, the saw includes a saw, an electro-hydraulic ram, and a saw frame. The saw and the electric hydraulic push rod are arranged on the saw frame. The saw frame mainly provides the support for saw, electronic hydraulic push rod to 40mm square steel is main raw and other materials, and the cooperation 90 angle spare connecting piece is fixed, and is whole all can to be dismantled, so that the later stage transportation improves with installing additional. Two proximity sensors are arranged on the saw frame up and down and used for detecting the upper limit position and the lower limit position of the saw, so that the electro-hydraulic push rod is not prone to being too high in ascending or too low in descending, and saw cutting action of the saw blade in an effective stroke interval is guaranteed. The saw machine comprises a cast iron type three-phase asynchronous motor, a woodworking alloy saw blade, a saw machine base and two V belts, wherein the three-phase asynchronous motor and the saw blade are in power transmission through the two V belts, and the saw machine base is connected with an electric hydraulic push rod through a Y-shaped joint. The sawing machine is mainly used for sawing raw bamboos, the electric hydraulic push rod mainly conducts lifting operation on the sawing machine by taking the main shaft as the circle center and taking the saw blade as arc motion through stroke extension, and the electric hydraulic push rod is matched with the rotating saw blade to cut the raw bamboos under the lifting action. The cutting principle of the bamboo sawing mechanism is as follows: the saw machine obtains the instruction of the controller, the electric hydraulic push rod contracts, and meanwhile, the three-phase asynchronous motor starts to drive the alloy woodworking saw blade to rotate through the V-shaped belt. At the moment, the whole sawing machine descends to saw and cut the original bamboo, so that the bamboo stump of the original bamboo can be completely cut off. When the base of the saw machine reaches the lower proximity sensor, the controller detects the signal change of the sensor, the contraction of the electric hydraulic push rod is stopped, the three-phase asynchronous motor is stopped, then the controller changes the power supply of the electric hydraulic push rod, the electric hydraulic push rod is reversely connected to extend the electric hydraulic push rod and push the whole saw machine to ascend, when the base of the saw machine ascends to a certain height, the signal change of the upper proximity sensor is detected by the controller, the action of the whole saw machine mechanism is stopped, and then the one-time complete saw cutting action of the saw machine mechanism is completed.

As shown in fig. 5, the blanking mechanism includes a blanking frame and a blanking plate. The unloading frame adopts the square steel to build, wholly can dismantle, convenient transportation and later stage improve. The blanking plate is obliquely arranged on the top layer of the blanking frame, and the inclination angle is about 30 degrees. The unloading board sets up to the slope, can effectively catch the length section bamboo surely that saw bamboo mechanism downcut, is convenient for decide the automatic bottom that rolls of length section bamboo to the unloading frame. The bottom layer of the blanking frame is an inclined plane, the fixed-length sections can be safely rolled to the ground, and finally the fixed-length sections are orderly and intensively arranged in one place, so that workers in the later period can carry the fixed-length sections conveniently.

As shown in fig. 5 and 6, in order to customize the cutting length of the raw bamboo, a first slide rail with scale lines is installed on the blanking frame, and a first photoelectric sensor is installed on the first slide rail through a slide block; and a second slide rail with scale marks is arranged on the conveying frame, and the second photoelectric sensor is arranged on the second slide rail through a slide block. The first photoelectric sensor can slide left and right on the first sliding block and is used for detecting whether the bamboo to be cut reaches the position, and when the bamboo to be cut reaches the position, the controller controls the rubber roller to stop conveying the raw bamboo and controls the saw mechanism to cut the bamboo. The vertical distance from the first photoelectric sensor to the saw blade is the set fixed length section cutting length. The second photoelectric sensor can slide left and right on the second sliding block and is used for judging whether the residual raw bamboo meets the cutting requirement of the fixed-length section, if the photoelectric sensor does not detect the raw bamboo signal, a signal is given to the controller, and the controller controls the rubber roller to stop conveying. The first slide rail and the second slide rail are respectively provided with a scale mark, the zero scale positions of the scale marks are fixed at the end close to the saw blade, the vertical distances from the two zero scale positions to the saw blade are the same and are recorded as c, the moving distances of the first photoelectric sensor and the second photoelectric sensor relative to the zero scale marks are d, and the length of the fixed-length section is c + d.

In the embodiment, the length adjustment of the fixed-length section is realized by adopting the structures of the sliding rail and the sliding block, and in the practical application process, the length adjustment can be also realized by using the combination of the ball screw linear guide rail and the sliding block. The position of the sliding block on the ball screw linear guide rail is controlled by the servo motor with high precision, and the automatic fixed-length section of the original bamboo is realized.

In order to discharge the bamboo which does not meet the requirement of fixed length section cutting, a push-out mechanism is arranged on the conveying mechanism. As shown in fig. 7, the push-out mechanism includes a first cylinder and a push plate. The first cylinder is installed in the middle-layer bottom of conveying frame, and the chevron type push pedal is installed on the push rod of first cylinder, when the push rod of first cylinder stretches out the action, can release former bamboo clout from the side of conveying roller, and after the completion of releasing, the cylinder push rod withdraws, accomplishes once and releases the action. The pushing mechanism completes the principle of pushing out the residual raw bamboo: when first photoelectric sensor detected the bamboo, the rubber wheel stopped to carry, and the saw carries out the cutting once, and whether the former bamboo clout on second sensor detection saw bit right was enough to satisfy the fixed length cutting next time this moment, if second photoelectric sensor signal changes, promptly detect former bamboo clout and be not enough to satisfy the fixed length cutting next time, and then through the shrink of controller control second cylinder, the pulling rubber gyro wheel rises, later ejecting mechanism once carries out the release action, accomplishes the clout and releases. The excess material is pushed out by the pushing-out mechanism, so that the excess material can be prevented from being pushed to the blanking mechanism by the conveying mechanism and is mixed up with the cut bamboo with the fixed length section. If make gear motor reversal this moment, return the feed inlet with the clout, because there is a section not little space between every group conveying roller, because the clout is too short when returning, press the perk by single rubber wheel easily, can not normally discharge. And if the motor reverses, the loss of the motor is easily caused, and the tilted original bamboo is blocked, so that the motor is easily burnt. The pushing mechanism of the invention can be used for pushing the excess materials from the side edge of the conveying roller, thereby avoiding the problems.

And the small-end bamboo joint needs to be removed while the length is fixed, as shown in fig. 8, an industrial camera and lighting equipment are arranged at the second slide rail and the second photoelectric sensor. The industrial camera is a color industrial camera and is used for image acquisition, and the lighting equipment is used for supplementing light for the camera and providing a stable illumination environment and is fixed with the industrial camera. The industrial camera and the lighting equipment are fixed on the sliding block and can slide left and right. The lighting equipment is electrically connected with a computer in the control box, and the computer performs judgment and analog signal output for the image identification by combining corresponding image identification software and algorithm, judges whether to avoid bamboo joints after transmitting the image identification and the analog signal output to the controller, and performs logic cutting. The principle of judging and cutting the small-end bamboo joint is as follows: industry camera, lighting apparatus, after second photoelectric sensor moved to the settlement position, when first photoelectric sensor detected the bamboo signal, the rubber wheel stopped conveying, the industry camera that is in the same position with second photoelectric sensor this moment begins discernment, if there is the bamboo joint if detect this position, then one section distance of controller control rubber wheel more conveying, in order to guarantee next time the little end cutting of former bamboo does not have the bamboo joint, after rubber wheel conveys one section distance, obtain a segment waste material by the sawing machine cutting, and then obtain the fixed length section bamboo that does not have the bamboo joint from the little end certain distance that accords with the mill and cuts open the bamboo requirement. In order to discharge this small piece of waste material, a space is provided between the saw mechanism and the conveyor mechanism from which the cut small piece of waste material can be slid by the waste slide to the ground for collection.

The left end of unloading mechanism is equipped with the baffle, and the baffle below is equipped with a proximity sensor, and when former bamboo propelling movement to here, the baffle blocks former bamboo, and proximity sensor detected signal changes this moment, and the controller stops all systems according to emergency, can effectively prevent the continuous conveying of former bamboo under the sensor failure condition to and whole system collapse failure's phenomenon from taking place.

The working principle of the invention is as follows: the bamboo sawing mechanism firstly saw original bamboos to remove bamboo stumps, then the saw blade position of the sawing machine is used as the starting position of the fixed-length section, and the vertical distance (the distance between the first photoelectric sensor and the second photoelectric sensor must be the same) from the first photoelectric sensor to the saw blade is used as the end of the fixed-length section. When the first sensor detects an original bamboo signal, the rubber wheel stops conveying, bamboo joint detection is carried out immediately after the industrial camera, and if no bamboo joint exists, the bamboo sawing mechanism starts sawing to form and obtain a fixed-length section; if there is the bamboo joint, saw bamboo mechanism cuts one section length section bamboo earlier, then the controller control rubber wheel removes a segment distance with former bamboo, and the industry camera detects once more, if there is not the bamboo joint, then the sawing machine descends and cuts, and the small segment waste material that the sawing machine cut this moment reachs the spaced area of unloading mechanism under the pushing action of rubber wheel, from the slip of waste material slide and concentrate the collection. Then the initial position of the fixed length section is determined again, and the bamboo sawing mechanism continues to saw the fixed length section at the new initial position of the fixed length section, so that the fixed length section without bamboo joints at a certain distance from the small end is produced.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
