Description

Technical Field

[0001] This utility model belongs to the field of factory-scale silkworm rearing, and specifically relates to a sensing mechanism of a silkworm rearing equipment feeding machine. Background Technology

[0002] Traditional silkworm rearing is a small-scale, family-run operation. This method is entirely manual, requiring manual intervention from egg to adult to cocoon harvesting. It is time-consuming, labor-intensive, and inefficient, and is limited by seasonal conditions, allowing silkworms to be raised only at specific times. The annual cocoon production is extremely low and cannot meet the demands of modern society, leading to its gradual obsolescence. To address the shortcomings of traditional small-scale silkworm rearing, large-scale, factory-style silkworm rearing techniques have emerged. To meet the requirements of large-scale silkworm rearing, silkworm rearing equipment such as silkworm frames and shelves were designed. This equipment enables the processes of silkworm rearing, transferring silkworms between different instars, and feeding. Specifically, this part of the silkworm rearing equipment is transported via a logistics line. During the transportation process, the feeding and the transfer and placement of shelves of different instars between different instar frames are completed. For example, after the third instar rearing is completed, the third instar silkworm frames and the third instar shelves inside, along with the first instar shelves, are placed on the fourth instar logistics line for transportation. During the transportation process, the third instar shelves are taken out and placed on the fourth instar silkworm frames on another fourth instar logistics line. At the same time, the fourth instar shelves are placed on the fourth instar silkworm frames and cover the third instar shelves inside. After feeding, the fourth instar silkworm frames are stacked and sent into the fourth instar silkworm rearing room.

[0003] In the aforementioned process, a robotic arm is typically used to grab and transfer three-year-old and four-year-old shelves. However, it is difficult to accurately supply the four-year-old shelves to the robotic arm. If the four-year-old shelves are stacked in the designed position, their height gradually decreases as the grabbing progresses, falling below the height the robotic arm can reach, making it unable to grab the shelves below. Obviously, this method is not suitable. Another method relies on workers to place each shelf in the designed position one by one. Although this allows for precise shelf grabbing, it increases the workload of workers and cannot provide a stable and continuous supply of shelves, making it subject to human intervention. Therefore, there is an urgent need to develop a device that can stably and continuously supply shelves.

[0004] To address this, a feeding machine with a conveying mechanism and a lifting mechanism was developed. The conveying mechanism transports stacked shelves into the feeding machine, while the lifting mechanism gradually raises the conveying mechanism. During the raising process, the shelves are sequentially grasped by a robotic arm, typically with one raising after each shelf is grasped. This feeding machine continuously supplies tools to the robotic arm, allowing them to be sequentially grasped and placed into the silkworm basket, achieving automated feeding. Clearly, this feeding machine needs to perform corresponding operations at different heights; therefore, position sensing is required for these specific heights. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding machine for silkworm rearing equipment. In view of the defects in the prior art, a sensing mechanism for the feeding machine is designed, including a proximity switch and a detection plate. The two can accurately detect whether the conveying mechanism has risen to the correct position and whether it has fallen to the correct position, thereby performing the corresponding operation and realizing the purpose of automated feeding.

[0006] To solve the above technical problems, the following technical solution is adopted:

[0007] A sensing mechanism for a silkworm rearing feeder is characterized by comprising a proximity switch and a detection plate, wherein the detection plate moves up and down with the conveying mechanism, and the proximity switch is used to sense the detection plate to identify the lifting position of the conveying mechanism.

[0008] Furthermore, the sensing mechanism also includes a mounting rod for mounting the proximity switch and the detection plate.

[0009] Furthermore, the proximity switch is mounted on the mounting rod via a proximity switch bracket.

[0010] Furthermore, the proximity switch is provided in two sets, one set is located at the high position of the mounting rod, and the other set is located at the low position of the mounting rod.

[0011] Furthermore, the sensing mechanism also includes a limit switch, which is used to sense the detection piece and plays a protective role. The limit switch is installed on the mounting rod.

[0012] Furthermore, the limit switch is mounted on the mounting rod via a limit switch bracket.

[0013] Furthermore, the limit switch is provided in two sets, one set is located at the high position of the mounting rod, and the other set is located at the low position of the mounting rod.

[0014] Furthermore, the detection sheet is a metal sheet.

[0015] The above technical solution has the following beneficial effects:

[0016] This invention designs a sensing mechanism for a feeding machine, including a proximity switch and a detection plate. Both can accurately detect whether the conveying mechanism has risen to the correct position or fallen to the correct position, thereby executing the corresponding operation to achieve the purpose of automated feeding.

[0017] This utility model also includes a limit switch for protection. When the proximity switch fails, the conveyor mechanism rises or falls further, and the limit switch is sensed and performs the corresponding operation, thus playing a role in protecting against proximity switch failure and preventing malfunctions.

Detailed Implementation

[0028] This utility model aims to provide a sensing mechanism for a feeding machine, including a proximity switch and a detection plate, which can accurately detect whether the conveying mechanism has risen to the correct position and fallen to the correct position, thereby performing corresponding operations to achieve the purpose of automated feeding.

[0029] The technical solution of this utility model will be described in detail below with reference to specific embodiments:

[0030] This sensing mechanism is used in a silkworm rearing equipment feeder, which supplies feed shelves to a robotic arm, such as... Figure 1As shown, it includes a frame 1 and a conveying mechanism 2, a lifting mechanism 4 and a support mechanism 5 installed on the frame 1. The conveying mechanism 2 is used to feed the shelves. The lifting mechanism 4 is connected to and controls the lifting of the conveying mechanism 2 to lift the shelves. The support mechanism 5 is used to support the remaining 5 shelves, thereby freeing the conveying mechanism 2 and resetting it to the bottom through the lifting mechanism 4 so that the next set of shelves can be fed into the feeder.

[0031] like Figure 2 As shown, the conveying mechanism 2 is a roller conveyor, which consists of multiple parallel rollers 21, with sleeves 22 connected to each roller 21. This roller conveyor connects to an external conveyor line to receive groups of shelves, eliminating the need for manual handling, saving time and effort, and enabling continuous material feeding.

[0032] To ensure stable lifting and lowering of the conveyor mechanism 2, the conveyor mechanism 2 is mounted on the bracket 3, such as... Figure 3 As shown, the bracket 3 consists of four steel rods and guide components 35. Steel rod 1 31 and steel rod 2 32 are arranged in parallel, and their front ends are connected by steel rod 3 33. Their rear ends are each connected to a set of guide components 35, and the two sets of guide components 35 are connected and fixed together by steel rod 4 34. Steel rod 1 31 and steel rod 2 32 are fixedly connected to the roller conveyor through flanges. Steel rod 4 34 is used to connect to the lifting mechanism 4, so that it can be driven to rise and fall by the lifting mechanism 4, thereby driving the roller conveyor and its shelves to rise and fall.

[0033] The guide assembly 35 is used for the lifting and lowering of the guide bracket 3, thereby improving its stability. For example... Figure 4 As shown, each guide assembly 35 includes a guide plate and guide wheels. There are two guide plates, namely a left guide plate 351 and a right guide plate 352. The left guide plate 351 and the right guide plate 352 are fixedly connected to steel rod 1 31 or steel rod 2 32. There are four types of guide wheels, namely front guide wheel 353, rear guide wheel 354, left guide wheel 355 and right guide wheel 356. There are two front guide wheels 353 located at the front end of the guide plate, two rear guide wheels 354 located at the rear end of the guide plate, two left guide wheels 355 located on the left guide plate 351, and two right guide wheels 356 located on the right guide plate 352. Two sets of guide components 35 are respectively installed on two vertical rods of the frame 1. The vertical rods pass between the left guide plate 351 and the right guide plate 352, so that the front guide wheel 353, the rear guide wheel 354, the left guide wheel 355 and the right guide wheel 356 are in the front, rear, left and right positions respectively. During lifting, the four types of guide wheels roll on each surface of the vertical rod to achieve the guiding function and improve the stability of lifting.

[0034] like Figure 5As shown, the lifting mechanism 4 includes a lifting motor 41, a main sprocket 43, a driven sprocket 45, and a chain 44. Two sets of main sprockets 43, driven sprockets 45, and chains 44 are provided. The lifting motor 41 synchronously drives the two main sprockets 43 via a main shaft 42, and the main sprockets 43 then drive the corresponding driven sprockets 45 and chains 44. The connector 441 of the two chains 44 is connected to the chain connector 36 of the bracket 3 connection. During transmission, the chains 44 drive the bracket 3, the conveying mechanism 2, and the equipment to rise and fall. Providing two sets of main sprockets 43, driven sprockets 45, and chains 44 improves the stability of the lifting process.

[0035] In addition, lifting mechanisms 4 can be installed on both the left and right sides of the bracket 3 to further improve the stability of lifting. A damping buffer (not shown in the figure) is provided on the frame 1. The damping buffer is located below the bracket 3 and is used to buffer the descent of the bracket 3 to improve stability.

[0036] like Figure 6 As shown, the upper end of the frame 1 is provided with a top cover 6, and the top cover 6 has a downwardly extending spout 61. The spout 61 has an opening 62, the shape of which matches the shape of the shelf, but the size is larger than the size of the shelf. The lifting mechanism 4 lifts the appliance through the opening 62 and to a position above it so that the robotic arm can grasp the appliance. Support mechanisms 5 are provided on both sides of the spout 61, with two sets on each side, such as... Figure 7 As shown, each support mechanism 5 includes a cylinder 51 and a claw 52. The cylinder 51 is mounted on the top cover 6 via a cylinder bracket 53 and is used to connect to and control the claw 52. The claw 52 is located at the through hole of the cover spout 61 and can extend and retract under the control of the cylinder 51. In the extended state, it can support the shelf, thereby freeing the conveying mechanism 2 so that it can descend, reset, and feed the next set of shelves. Each claw 52 is also equipped with two clamping plates 521, which can clamp the shelf and improve the stability of the support.

[0037] like Figure 8As shown, the feeder also includes a sensing mechanism 7, which includes a mounting rod 71, a proximity switch 73, a detection plate 72, and a limit switch 75. The mounting rod 71 is connected to the frame 1 and is vertically arranged. The proximity switch 73 is mounted on the mounting rod 71 via a proximity switch bracket 74, and the limit switch 75 is mounted on the mounting rod 71 via a limit switch bracket 76. There are two sets of proximity switches 73 and limit switches 75. One set is installed at a high position to identify whether the conveying mechanism 2 and the bracket 3 have reached the highest position. After identifying that position, the support mechanism 5 is activated to support the remaining shelves, and then the lifting mechanism 4 is lowered to lower the conveying mechanism 2 and the bracket 3. The other set is installed at a low position to identify whether the conveying mechanism 2 and the bracket 3 have lowered and reset. After identifying that position, the lifting mechanism 4 stops, and the next set of shelves is fed onto the conveying mechanism 2. The detection plate 72, made of metal, is mounted on the guide assembly 35 and moves up and down with the bracket 3. When it rises to the designed high position, the high-position proximity switch 73 is activated, recognizing that the conveyor mechanism 2 and the bracket 3 have reached their highest position. When the detection plate 72 descends to the designed low position, the low-position proximity switch 73 is activated, recognizing that the conveyor mechanism 2 and the bracket 3 have reached their reset position. Based on the proximity switch 73 and the detection plate 72, the conveyor mechanism 2 can accurately detect whether it has risen and fallen to the correct positions, thereby executing corresponding operations to achieve automated material feeding.

[0038] Limit switch 75 serves a protective function. When proximity switch 73 fails, the conveyor mechanism 2 will rise or fall further. At this time, limit switch 75 will be sensed and perform the corresponding operation, thus playing the role of protection against the failure of proximity switch 73 and preventing malfunction.

[0039] The feeder of this utility model can also be equipped with several sensors, including a sensor for detecting whether the shelf group is conveyed to the conveying mechanism, a sensor for detecting whether the shelf group has risen to a level that can be grasped by the robotic arm, a sensor for detecting whether the current shelf group has been completely grasped, etc., which can be adaptively set and adjusted according to the actual working conditions.

[0040] The material feeding process of this utility model is as follows:

[0041] 1. The conveyor mechanism 2 starts and feeds the group of shelves into place. The conveyor mechanism 2 stops after the shelves are in place.

[0042] 2. The lifting mechanism 4 is activated to raise the shelf. During the raising process, the robotic arm gradually grabs the shelf.

[0043] 3. When the height is raised to the high position, the proximity switch 73 at the high position senses the detection plate 72, activates the support mechanism 5, supports the remaining shelf, and then lowers the lifting mechanism 4 and the conveying mechanism 2.

[0044] 4. After the descent and reset, the low-position proximity switch 73 senses the detection plate 72, closes the lifting mechanism 4 and starts the conveying mechanism 2 to send the next set of shelves in.

[0045] 5. After the remaining shelves in step 3 have been picked up, the support mechanism 5 resets and the above steps are repeated to feed the next set of shelves.

[0046] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
