DETAILED DESCRIPTION

[0031] It should be noted that the following detailed description is merely exemplary in nature and is intended to provide further description of the application. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0032] It is to be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments consistent with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0033] As Figures 1-14As shown, the induction recognition-based bamboo shoot automatic head cutting operation equipment comprises a PLC industrial computer and a bamboo shoot conveying device 100 for guiding the head end of the bamboo shoot to be conveyed forward, the bamboo shoot conveying device 100 is provided with a head cutting station and an induction device 240, a moving frame 200 driven by an electric reciprocating mechanism is arranged above the head cutting station, one side of the moving frame 200 is provided with a cutter mechanism and a cutter lifting mechanism, and the other side is provided with a head positioning mechanism 210, the head positioning mechanism 210 comprises a row of double-head cylinders 211 arranged in a vertical direction and controlled and driven by the same air source through the PLC industrial computer and an electromagnetic valve, all the double-head cylinders 211 can be controlled by the same electromagnetic valve or each double-head cylinder can be controlled by an independent electromagnetic valve, the double-head cylinders are arranged in parallel to the conveying direction of the bamboo shoot, the lower end of each double-head cylinder is fixedly connected with a probe 212 for inserting into the bamboo shoot, and the upper end of each double-head cylinder is a probe positioning end 213 which can be inducted by the induction device to determine the insertion depth of the probe; the working steps are as follows: (1) the probes of each double-head cylinder complete the downward puncture stroke of the edible part and the inedible part of the bamboo shoot through the control of the PLC industrial computer and the electromagnetic valve; (2) the height difference of the probe positioning ends corresponding to the edible part and the inedible part of the bamboo shoot is inducted by the induction device (the height difference is caused by the different hardness of the edible part and the inedible part of the bamboo shoot, which makes the downward puncture stroke of the probe different) to determine the junction of the edible part and the inedible part as the head cutting position; (3) each double-head cylinder is returned through the control of the PLC industrial computer and the electromagnetic valve; (4) the cutter mechanism is moved to the head cutting position by driving the moving frame through the step motor of the electric reciprocating mechanism controlled by the PLC industrial computer, and the cutting-off work of the shoot head is completed through the control of the cutter lifting mechanism and the cutter mechanism by the PLC industrial computer. When the bamboo shoot head cutting operation is performed, all the double-head cylinders of the head positioning mechanism 210 puncture into the bamboo shoot with the same pressure, and the edible part of the bamboo shoot is softer and easier to be punctured than the inedible part; the pressure of the double-head cylinder is set according to the hardness of the junction of the edible part and the inedible part, the probe corresponding to the edible part can be moved downward all the time, and the probe positioning end of the corresponding double-head cylinder is in the lowest position and cannot be inducted by the induction device 240; the probe corresponding to the inedible part cannot be moved downward all the time due to the block of the harder shoot, the probe positioning end of the corresponding double-head cylinder does not reach the lowest position and can be inducted by the induction device 240, and the intermediate position between the two adjacent probes which are moved downward all the time and not moved downward all the time is determined as the head cutting position. Taking five probes as an example: as shown in Figure 5 if the front three probes are not moved downward all the time and the rear two probes are moved downward all the time, the head cutting position is the intermediate position of the third probe and the fourth probe; as shown in Figure 6 if the front two probes are not moved downward all the time and the rear three probes are moved downward all the time, the head cutting position is the intermediate position of the second probe and the third probe. The more the number of probes is, the higher the detection accuracy is.

[0034] The lowest position of the probe is set to be close to the conveying surface of the bamboo shoot conveying device 100, so as to avoid the damage of the probe and the conveying surface of the bamboo shoot conveying device 100 caused by the contact between them.

[0035] In the embodiment, the sensing device 240 is also several and is arranged one-to-one with the double-end cylinders. Each sensing device forms a vertical sensing area with at least one pair of light emitting end 241 and light receiving end 242. In the detection, the probe penetration time is the time when the probe can penetrate the bamboo shoot to the lowest position under the thrust of the double-end cylinder. During the penetration process, if the probe penetrates the bamboo shoot, the corresponding cutter positioning end of the probe will be lowered to a position out of the vertical sensing area, as shown in FIG. 6. If the probe cannot penetrate the bamboo shoot due to the obstruction of the inedible part of the bamboo shoot, the corresponding cutter positioning end of the probe can shield at least one light receiving end, as shown in FIG. 7. Figure 8 Figure 7

[0036] In the embodiment, all the double-end cylinders are supplied with compressed gas from a compressed gas source. A buffer gas chamber is arranged on the connecting pipeline between the compressed gas source and the double-end cylinders. A pressure regulating valve is arranged on the input end of the buffer gas chamber. The output end of the buffer gas chamber is communicated with each double-end cylinder. The compressed gas source supplies all the double-end cylinders with gas through the buffer gas chamber, so as to ensure that the pressures of all the double-end cylinders are consistent. The pressure regulating valve is used to regulate the pressure.

[0037] In the embodiment, a liftable baffle 140 controlled by a PLC industrial computer is arranged on the front side of the cutting head station. A liftable bamboo shoot tail supporting plate 110 controlled by the PLC industrial computer is arranged on the rear side of the cutting head station. The baffle 140 is provided with a sensing switch 141 controlled by the PLC industrial computer on the corresponding side surface of the bamboo shoot head. The sensing switch 141 is used to control the shutdown of the bamboo shoot conveying device and the lifting of the bamboo shoot tail supporting plate. After the cutting knife mechanism completes the cutting of the bamboo shoot head, the PLC industrial computer controls the lifting of the baffle and the lowering of the bamboo shoot tail supporting plate. When the bamboo shoot reaches the cutting head station, the baffle is used to block the bamboo shoot. The sensing switch is used to determine whether the bamboo shoot is in place. After the sensing switch senses that the bamboo shoot is in place, the PLC industrial computer controls the lifting of the bamboo shoot tail supporting plate 110 to a certain height, so as to lift the tail end of the bamboo shoot upward, so that the bamboo shoot is in a horizontal state as much as possible. After the cutting of the bamboo shoot is completed, the bamboo shoot tail supporting plate is lowered, so as to avoid blocking the next bamboo shoot.

[0038] In the embodiment, a V-shaped positioning groove 111 is arranged on the upper side of the bamboo shoot tail supporting plate, so as to have a positioning effect and avoid the deflection of the tail of the bamboo shoot.

[0039] ​​In the embodiment, the bamboo shoot conveying device is an intermittent conveying device, the bamboo shoot conveying device 100 is composed of two front and rear conveying machines, the bamboo shoot tail support plate is located at the joint of the two conveying machines, a first air cylinder 130 for driving the lifting of the bamboo shoot tail support plate is arranged below the bamboo shoot tail support plate, and a PLC industrial computer controls the action of the first air cylinder through an electromagnetic valve; a transition plate 120 is arranged at the joint of the two conveying machines, and a gap hole for the bamboo shoot tail support plate to pass through is arranged on the transition plate. The bamboo shoot conveying device 100 adopts an intermittent motion mode, the start and stop of the motor of the conveying machine are controlled by the PLC industrial computer to realize the intermittent motion of the bamboo shoot conveying device, and each time the bamboo shoot conveying device moves, the bamboo shoot with a cutting head is sent into the cutting head station, and the bamboo shoot with a completed cutting head is sent out of the cutting head station. The conveying machine adopts a chain plate conveyor or a belt conveyor.

[0040] In the embodiment, the baffle is fixedly connected to one end of a swing arm 310; the other end of the swing arm is hingedly connected to a fixed frame 300 located beside the conveying machine, a second air cylinder 320 for driving the swing arm to swing up and down is arranged on the fixed frame 300, the extension rod of the second air cylinder is hingedly connected to the swing arm, and the cylinder body of the second air cylinder is hingedly connected to the fixed frame; a limiting block 330 for keeping the swing arm in a horizontal position when the swing arm swings down is fixedly connected to the fixed frame; after the cutting head operation of the bamboo shoot is completed, the PLC industrial computer controls the action of the second air cylinder through an electromagnetic valve, the baffle is lifted by the swing arm to allow the bamboo shoot with a completed cutting head to pass, and then the baffle is lowered to block the next bamboo shoot.

[0041] In the embodiment, the electric reciprocating mechanism adopts a screw linear slide 400, and the cutter lifting mechanism adopts a third air cylinder 250, which is installed on one side of the moving frame 200. The cutter mechanism includes a cutter holder 260 located on the lower side of the moving frame 200 and driven to lift by the third air cylinder 250, and the cutter 220 is installed on the lower side of the cutter holder. The moving distance of the moving frame can be accurately controlled by the PLC industrial computer through the stepping motor of the screw linear slide 400, so that the position of the cutter can be accurately positioned. The distance between each probe position and the cutter is fixed, and the distance parameters between each probe position and the cutter are set in the PLC industrial computer. After the position of the cutting head is determined, the PLC industrial computer can quickly and accurately move the cutting head to the position above the cutting head through the stepping motor of the screw linear slide 400, and then the PLC industrial computer controls the action of the third air cylinder through an electromagnetic valve to drive the cutting head to move downward to complete the cutting head operation. Then, the PLC industrial computer controls the third air cylinder and the stepping motor of the screw linear slide 400 respectively to reset the cutting head and the moving frame. The lowest position of the downward movement of the cutting head is the position at which the cutting edge of the cutting head is close to the conveying surface of the bamboo shoot conveying device 100.

[0042] In the embodiment, the bamboo shoot conveying device is provided with side baffles 150 on both sides, and the cutting head station is provided with positioning blocks 161 driven by fourth cylinders 160 on both sides. The fourth cylinders 160 are controlled by a PLC industrial computer through electromagnetic valves, and the positioning blocks are wedge-shaped. Through the action of the positioning blocks 161 on both sides, the bamboo shoot is centered and is prevented from being inclined at the cutting head station. Meanwhile, the bamboo shoot can be effectively fixed to prevent the bamboo shoot from being lifted when the probe moves upward. The positioning blocks are arranged close to the tail end of the bamboo shoot, so that the positioning position is the edible part of the bamboo shoot. After the cutting head operation is completed, the two positioning blocks are loosened, and the pressure of the fourth cylinder driving the positioning block does not need to be too large.

[0043] After the cutting head operation of the bamboo shoot is completed, the head part (i.e. the inedible part) cut from the bamboo shoot is removed. How to remove the head part does not belong to the scope of the present application, and will not be described in detail here. The bamboo shoot conveying device can continue to convey the edible part and the inedible part cut after cutting to the front, and the inedible part is removed by manual operation. Alternatively, a pushing plate can be arranged on one side of the cutting head station close to the baffle position, and the pushing plate is driven by a cylinder to push the cut head part to the other side to make it exit the bamboo shoot conveying device.

[0044] In the embodiment, the bamboo shoot conveying device is provided with a bamboo shoot chute 500 at the rear, and the bamboo shoot chute is provided with a lifting conveying belt 600 for lifting the bamboo shoot on one side. The width of the lifting conveying belt 600 is slightly larger than the length of the bamboo shoot, and a plurality of groups of material pushing assemblies 610 are arranged on the lifting conveying belt in a spaced manner. Each group of material pushing assemblies is arranged on one side of the lifting conveying belt and is located on one side of the lifting conveying belt so that the head end of the bamboo shoot can be lifted when the head end of the bamboo shoot is located on the material pushing assembly, and the tail end of the bamboo shoot can fall off by itself when the tail end of the bamboo shoot is located on the material pushing assembly. Since the bamboo shoot is conical, the head end is light, and the tail end is light. By utilizing this characteristic of the bamboo shoot, the orientation of the bamboo shoot is controlled before the bamboo shoot is fed into the bamboo shoot conveying device, so that the head end of the bamboo shoot is forward and the tail end of the bamboo shoot is backward after the bamboo shoot enters the bamboo shoot conveying device. When the lifting conveying belt 600 lifts the bamboo shoot upward through the material pushing assemblies 610, if the head end of the bamboo shoot is located above the material pushing assemblies 610, the bamboo shoot will be lifted upward; if the tail end of the bamboo shoot is located above the material pushing assemblies 610, the bamboo shoot will automatically fall back into the bamboo shoot chute 500 and participate in lifting again. In this way, the bamboo shoot is conveyed one by one, and the head end of the bamboo shoot lifted is ensured to be in one direction, i.e. toward the right side of the lifting conveying belt, as shown in FIG. 8. Figure 11

[0045] ​In the embodiment, in order to adapt to the tapered structure of bamboo shoots, the lengths of the prying claws of each group of prying assemblies gradually increase from the middle to the sides, and the ends of the prying claws are upwardly curved to avoid the bamboo shoots from rolling down from the end positions of the prying claws; a discharging chute 700 is arranged between the upper end of the lifting conveyor belt and the bamboo shoot conveying device, and an upper accommodation groove 710 corresponding to the positions of the prying claws is arranged at the upper end of the discharging chute. The lifted bamboo shoots slide down along the discharging chute 700 to the bamboo shoot conveying device. Since the heads of the bamboo shoots lifted to the upper end of the lifting conveyor belt are all in one direction, and the heads are downwardly curved during the sliding process, it is ensured that the bamboo shoots sent to the bamboo shoot conveying device are basically with the heads in front. If the positions of the heads and tails are exchanged during the sliding process, the bamboo shoots can be manually removed. In the specific implementation process, the bamboo shoot chute can also not be arranged, and the heads of the bamboo shoots can be directly placed on the bamboo shoot conveying device by manual operation. However, this way is extremely low in efficiency.

[0046] In the embodiment, the inner bottom of the bamboo shoot chute is provided with an inclined bottom plate 510 downwardly inclined toward the side of the lifting conveyor belt, and a lower accommodation groove 511 corresponding to the positions of the prying claws is arranged at the lower position of the inclined bottom plate. The bamboo shoot chute is symmetrically provided with a central guide plate 520 extending to the two sides of the conveyor belt along the inclined direction on both sides of the lifting conveyor belt. The inclined bottom plate 510 and the central guide plate 520 can automatically collect the bamboo shoots in the bamboo shoot chute to the middle.

[0047] The specific working process of the bamboo shoot automatic head cutting operation equipment based on inductive recognition is as follows:

[0048] (1) The PLC industrial computer controls the motor of the lifting conveyor belt to work, and uses the lifting conveyor belt to sequentially convey the bamboo shoots in the bamboo shoot chute outward. The head ends of the conveyed bamboo shoots are all in one direction, and the heads of the bamboo shoots sent to the bamboo shoot conveying device are in front. The PLC industrial computer controls the motor of the bamboo shoot conveying device to work, and uses the bamboo shoot conveying device to intermittently convey the bamboo shoots forward;

[0049] (2) The baffle is in the initial state of the downward position, and when the bamboo shoots reach the head cutting station, the head ends of the bamboo shoots are blocked by the baffle, and the inductive switch senses the arrival of the bamboo shoots;

[0050] (3) The inductive switch sends a signal to the PLC industrial computer, and the PLC industrial computer controls the first cylinder and the fourth cylinder to act through the electromagnetic valve. The first cylinder drives the bamboo shoot tail support plate to be lifted, and the fourth cylinder drives the two side positioning pressing blocks to press the bamboo shoots;

[0051] (4) PLC industrial computer controls double-headed cylinder to act through electromagnetic valve, all double-headed cylinders drive corresponding probe to move downward with same pressure, and the intersection of edible part and inedible part of bamboo shoots is determined as cutting head position through the penetration stroke difference of probe to bamboo shoots edible part and inedible part, and the intermediate position between two adjacent probes moving downward and not moving downward is determined as cutting head position;

[0052] (5) PLC industrial computer controls double-headed cylinder to act through electromagnetic valve, all double-headed cylinders drive corresponding probe to move upward to reset;

[0053] (6) PLC industrial computer controls stepping motor of screw linear slide to work, screw linear slide drives moving frame to move to make cutter move above cutting head position, then PLC industrial computer controls third cylinder to act through electromagnetic valve, third cylinder drives cutting head to move downward to complete cutting head operation, then PLC industrial computer controls electromagnetic valve of third cylinder and stepping motor of screw linear slide 400 respectively to make third cylinder and screw linear slide drive cutter and moving frame to reset respectively;
