Description

Technical Field

[0001] This invention belongs to the technical field of object conveying equipment, and particularly relates to a sample bottle flipping conveying device. Background Technology

[0002] Water sample testing typically involves sampling water from different areas and depths, placing the samples into different sample bottles, and then sending the sample bottles containing the water samples to the testing station for testing. During testing, a predetermined amount of water is drawn multiple times from the sample bottles using a pipette to obtain multiple samples. Then, each sample is subjected to different tests to obtain the desired test results.

[0003] After the water is extracted from the sample vials, water remains inside. To reuse the vials, the water usually needs to be poured out, followed by cleaning. Current methods often involve manual pouring out the water from each vial, a repetitive process that is tiring and inefficient. While some devices can automatically empty the vials, the water can easily flow along the vial's outer wall onto the work surface. If the collected water sample contains contaminated water, this can also pollute the work surface, affecting the working environment. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention provides a sample bottle flipping and conveying device. By flipping the conveyed sample bottles in batches and then continuing to convey them to the next process, the efficiency of flipping and tilting sample bottles is improved, and the contamination of the carrier plate when water samples are poured out can be effectively avoided.

[0005] In order to achieve the objective of this invention, the following solution is proposed:

[0006] A sample vial tilting and conveying device is located on one side of the end of a conveying mechanism in the conveying direction. One side of the end of the conveying mechanism has an opening, and the other side has a pushing member for pushing a sample vial that is upright in the direction of the opening. The device includes:

[0007] The clamping assembly includes a support plate with a corresponding opening for receiving sample vials. A vertical plate is located on the side of the support plate away from the opening, and a horizontal plate is located on the side of the vertical plate away from the support plate. The vertical plate has an array of strip-shaped holes along its length, and a set of clamping plates is symmetrically arranged within each strip-shaped hole. The middle section of the clamping plates in the same set is rotatably connected to the strip-shaped hole. A first spring is provided between one end of each clamping plate in the same set. When the first spring is in its natural state, the other end of the clamping plates in the same set is in an open state. A spreading member is provided on the horizontal plate, with both ends of the spreading member protruding from both ends of the horizontal plate. The two ends of the horizontal plate are rotatably set... The device includes a limiting component, which includes a rotating rod rotatably connected to one end of a horizontal plate. The upper end of the rotating rod protrudes from the top surface of the horizontal plate, and a connecting rod is vertically provided at the lower end of the rotating rod. A reset rod is vertically provided on the side of the vertical plate facing the horizontal plate, and a second spring passes through the reset rod. The middle part of the connecting rod is slidably connected to the reset rod. The second spring is located between the outer end of the reset rod and the connecting rod. A limiting rod is provided at one end of the connecting rod, and one end of the limiting rod is slidably connected to the bottom of the bearing plate. A spreading component is used to spread open one end of a set of clamping plates so that the other end of the clamping plates is closed, and to push the rotating rod to rotate so that the limiting rod releases the limiting on the bearing plate.

[0008] The flipping components are located at the middle of both ends of the vertical plate. They are used to flip the clamping components after a set of clamping plates have finished clamping, so that the sample bottle can be flipped 180°. The upper end of the flipping components is connected to a linear mechanism, which is used to transport the flipped sample bottle to the next process.

[0009] Furthermore, a guide rod is provided inside the strip hole, and one end of a set of clamping plates is provided with a waist-shaped hole and a pin. The waist-shaped hole faces the side of the bearing plate, and the pin faces the side of the horizontal plate. The pin is rotatably connected to the strip hole, and the waist-shaped hole is slidably engaged with the guide rod. The first spring passes through the guide rod.

[0010] Furthermore, the opening component includes a first cylinder disposed on the horizontal plate, the output end of which is provided with a strip plate, the two ends of which protrude from the two ends of the horizontal plate for pushing one end of the limiting component, and one side of the strip plate is provided with push blocks arranged in an array for opening one end of a set of clamping plates.

[0011] Furthermore, the push block includes a triangular block and a rectangular block located on the horizontal segment of the triangular block. The triangular block has an isosceles structure, and the apex of the triangular block faces a set of clamping plates.

[0012] Furthermore, a U-shaped groove is recessed inward from the center of the apex of the triangular block, and the opening height of the U-shaped groove is greater than the outer diameter of the first spring.

[0013] Furthermore, the bottom of the vertical plate is provided with a support lug, and a rectangular hole is passed through the support lug. The reset rod is vertically set on one side of the support lug, and a notch is provided on the other side of the support lug. A set of slides is provided at both ends of the bottom of the bearing plate. The width of the slides is the same as the depth of the notch. The slides are provided with elongated holes. Rotating pins are provided on both sides of one end of the limiting rod. The rotating pins are in rolling engagement with the elongated holes.

[0014] Furthermore, the end of the slide facing the vertical plate protrudes beyond the bottom of the support plate by a predetermined length, and the protruding end of the slide has an arc structure. The center of the end of the elongated hole facing the vertical plate is coaxial with the hinge point at the bottom of the vertical plate and the support plate.

[0015] Furthermore, the flipping assembly includes a base, on which a rack is movably mounted. A second cylinder is mounted at one end of the rack, and a vertical plate is mounted on one side of the rack. A connecting shaft passes through the lower end of the vertical plate. One end of the connecting shaft is connected to the end of the vertical plate, and the other end is equipped with a gear that meshes with the rack. The upper end of the vertical plate is connected to the output end of a linear mechanism.

[0016] Furthermore, the top surface of the support plate is provided with multiple slides, one end of which is connected to the side of the support plate facing the pusher, and the two side walls of the support plate connected to the slide are respectively provided with arc surfaces.

[0017] The beneficial effects of this invention are as follows:

[0018] During the process of the supporting component pushing a set of clamping plates to hold the sample bottle, the supporting component simultaneously pushes the upper end of the rotating rod to rotate towards the vertical plate, so that the lower end of the rotating rod drives the limiting rod to move, so that the limiting rod releases the limiting on the carrier plate, thereby causing the carrier plate to rotate away from the bottom of the sample bottle. When the sample bottle rotates towards the lower end of the conveying device with the flipping component, the sample bottle can be flipped, which can prevent water from flowing along the surface of the sample bottle onto the carrier plate, effectively avoiding contamination of the carrier plate. Then, the flipped sample bottle is conveyed to the next process through the linear mechanism. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0032] like Figures 1-10As shown in the figure, this embodiment discloses a sample bottle flipping and conveying device, which is installed at the end of the conveying direction of the conveying mechanism 1. It includes a clamping component, a flipping component 400, etc. The clamping component is used to clamp and position the sample bottles 2 containing water conveyed by the conveying mechanism 1 in batches. The flipping component 400 is used to drive the clamping component holding the sample bottle 2 to flip 180° so that the sample bottle 2 pours water into a predetermined collection pool for collection. Then, the sample bottle 2 with the water poured out moves in a predetermined direction so that the sample bottle 2 with the water poured out enters the next processing step, thereby replacing manual operation and improving work efficiency.

[0033] Specifically, such as Figures 1-2 As shown, the conveying mechanism 1 has an opening 11 on one side of the end of the conveying direction and a pusher 12 on the other side. A sensor is set on the side of the pusher 12 facing the opening 11 to detect the number of sample bottles 2 entering the side of the pusher 12 facing the opening 11. When a predetermined number of sample bottles 2 enter the front of the pusher 12 in a positive vertical position, the pusher 12 pushes the sample bottles 2 towards the opening 11.

[0034] like Figure 2 As shown, the clamping assembly includes a support plate 100, a vertical plate 200, and a horizontal plate 300. The support plate 100 is located on one side of the conveying mechanism 1 at the end of the conveying direction corresponding to the opening 11. The vertical plate 200 is vertically located on the side of the support plate 100 away from the opening 11, and the bottom of the vertical plate 200 is connected to one side of the bottom of the support plate 100 by a hinge plate. The horizontal plate 300 is vertically located on the side of the vertical plate 200 away from the support plate 100, and is arranged parallel to the support plate 100.

[0035] Preferred, such as Figure 3 As shown, the top surface of the support plate 100 is provided with multiple slides 120. The slides 120 are arranged in an array along the conveying direction perpendicular to the conveying mechanism 1. One end of the slide 120 is connected to the side of the support plate 100 facing the pusher 12. The two side walls of the slide 120 connected to the side of the support plate 100 are respectively provided with arc surfaces 121, so that the side of the slide 120 facing the opening has a V-shaped structure, which makes it easier for the sample bottle 2 to enter the slide 120 better.

[0036] like Figures 4-6As shown, a series of strip-shaped holes 210 are arranged along the length of the vertical plate 200, and the strip-shaped holes 210 penetrate both sides of the vertical plate 200. A set of clamping plates 220 are symmetrically arranged in each strip-shaped hole 210. One end of the clamping plate 220 in the same set is rotatably connected to the strip-shaped hole 210, and the other end extends to the top surface of the support plate 100 for clamping the sample bottle 2. The clamping plate 220 in the same set has a waist-shaped hole 222 and a pin 223 located in the strip-shaped hole 210. The waist-shaped hole 222 and the pin 223 are located on both sides of the line of symmetry along the length of the strip-shaped hole 210. The waist-shaped hole 222 is located in the middle section of the same set of clamping plates 220, so that the waist-shaped hole 222 is located on the side facing the support plate 100, and the pin 223 is located on the side facing the horizontal plate 300.

[0037] A guide rod 211 is provided on the side of the strip hole 210 facing the support plate 100. The axis of the guide rod 211 is consistent with the length direction of the strip hole 210. A first spring 221 is provided between the two ends of the same set of clamping plates 220, and the first spring 221 passes through the guide rod 211. The waist-shaped hole 222 of the same set of clamping plates 220 is slidably engaged with the guide rod 211. This allows the same set of clamping plates 220 to extend to one end of the support plate 100 in a natural state and remain open to form a clamping area, so that the pusher 12 can directly push the sample bottle 2 into the clamping area.

[0038] like Figures 7-8 As shown, a support member 310 is provided on the horizontal plate 300. The output end of the support member 310 is set towards the vertical plate 200. When the sample bottle 2 enters the clamping area, the support member 310 is used to move in the direction of the strip hole 210. The output end of the support member 310 pushes one end of the same set of clamping plates 220 to rotate around the axis of the pin 223 connected to the strip hole 210 towards the two ends of the corresponding strip hole 210, and the other end moves relative to it, thereby clamping the sample bottle 2.

[0039] Limiting members 320 are rotatably provided at both ends of the horizontal plate 300. The upper end of the limiting member 320 protrudes from the top surface of the horizontal plate 300 and is located on the moving trajectory of the output end of the supporting member 310. The lower end of the limiting member 320 is slidably provided at the bottom of the bearing plate 100 so that the bearing plate 100 remains parallel to the horizontal part 300. When the output end of the spreading member 310 moves toward the clamping plate 220, the output end of the spreading member 310 pushes the upper end of the limiting member 320 to rotate toward the direction of the vertical plate 200, so that the lower end of the limiting member 320 gradually slides out of the bottom of the support plate 100. When each set of clamping plates 220 is clamped, the lower end of the limiting member 320 completely moves out of the bottom of the support plate 100, thereby releasing the limitation on the bottom of the support plate 100. Under the action of gravity of the support plate 100, the support plate 100 rotates downward around the hinge point between the support plate 100 and the vertical plate 200 to move away from the bottom of the sample bottle 2, so as to avoid contaminating the surface of the support plate 100 when the sample bottle 2 is poured with water.

[0040] like Figures 1-2 As shown, the flipping components 400 are respectively located at the middle of both ends of the vertical plate 200. After each set of clamping plates 220 has finished clamping the sample bottle 2 on the support plate 100, the flipping components 400 flip the clamping components. In order to avoid water remaining in the sample bottle 2, the flipping components 400 usually drive the clamping components to flip 180° so that the water in the sample bottle 2 can be completely poured out. The upper end of the flipping components 400 is connected to a linear mechanism. After the water in the sample bottle 2 has been completely poured out, the linear mechanism is used to drive the flipping components 400, the clamping components, and the sample bottle 2 to move linearly to the next process.

[0041] Specifically, linear mechanisms can be driven by linear cylinders or by motor-driven lead screws.

[0042] Specific operating procedures:

[0043] The conveying mechanism 1 transports the sample bottle 2 to the end in a positive, upright position. When the sensor on the pusher 12 detects a predetermined number of sample bottles 2, the pusher 12 is activated and the conveying mechanism 1 is paused, so that the pusher 12 pushes the predetermined number of sample bottles 2 onto the support plate 100 in the direction of the opening 11. Then, the opening member 310 is activated, so that the opening member 310 pushes one end of the same set of clamping plates 220 in each strip hole 210 to rotate towards the two ends of the corresponding strip hole 210, so that the other end of the same set of clamping plates 220 clamps the sample bottle 2.

[0044] After clamping is completed, the spreading member 310 continues to move towards the vertical plate 200 so that the lower end of the limiting member 320 moves out of the bottom of the support plate 100, thereby releasing the limiting of the bottom of the support plate 100, so that the support plate 100 rotates downward around the hinge point with the bottom of the vertical plate 200, thereby rotating away from the bottom of the sample bottle 2.

[0045] Activate the flipping assembly 400, causing it to drive the clamping assembly to flip towards the side of the conveying mechanism 1. This causes the flipping assembly 400 to drive the clamping assembly to rotate, thus synchronously rotating the clamped sample bottle 2. The sample bottle 2 is flipped 180° to a vertical inverted position to empty the water inside. Then, activate the linear mechanism, causing it to drive the flipping assembly 400, the clamping assembly, and the empty sample bottle 2 to move to the next stage. This causes the output end of the support member 310 to move away from the vertical plate 200, releasing the support member 310 from limiting the clamping plates 220. This allows the sample bottle 2 to automatically fall into the predetermined area of ​​the next stage, facilitating the operation of the next step. At this point, the linear mechanism is restarted, causing it to drive the flipping assembly 400 and the clamping assembly to reset. During the reset process of the flipping assembly 400, the output end of the spreading member 310 completely moves away from one end of each set of clamping plates 220, causing the same set of clamping plates 220 to reset to their initial state under the action of the first spring 221. As the output end of the spreading member 310 gradually moves away from the upper end of the limiting member 320, the upper end of the limiting member 320 loses its thrust, causing the lower end of the limiting member 320 to slide back to the bottom surface of the support plate 100, thus resetting the support plate 100. The flipping assembly 400 drives the clamping assembly to reset. When the sensor detects that the clamping assembly has reset, the conveying mechanism 1 is restarted to convey the sample bottle 2, and this process is repeated.

[0046] Specifically, such as Figures 7-8 As shown, to prevent the support plate 100 from rotating when water is poured from the sample bottle 2, a slide 110 is provided at the bottom of the support plate 100. The slide 110 is arranged along the side perpendicular to the vertical plate 200 facing the support plate 100, and the end of the slide 110 facing the vertical plate 200 extends out of the bottom of the support plate 100 by a predetermined length. An elongated hole 111 is provided along the length direction of the slide 110, so that the end of the elongated hole 111 facing the vertical plate 200 is coaxial with the rotation axis of the hinge plate. The bottom ends of the vertical plate 200 are respectively provided with lugs 240, and the lugs 240 are provided with rectangular holes 241. A reset rod 230 is provided on one side of the rectangular hole 241, and the reset rod 230 is located below the horizontal plate 300. A second spring 231 is provided on the reset rod 230. The side of the lugs 240 facing the support plate 100 is provided with a notch 242, and the depth of the notch 242 is the same as the length of the slide 110 extending out of the bottom of the support plate 100.

[0047] The limiting component 320 includes a rotating rod 321, which is rotatably connected to the end of the horizontal plate 300. The upper end of the rotating rod 321 protrudes from the top surface of the horizontal plate 300. A connecting rod 322 is vertically provided at the lower end of the rotating rod 321. A connecting hole is provided along the axis perpendicular to the connecting rod 322, so that the reset rod 230 cooperates with the connecting hole, thereby the connecting rod 322 and the reset rod 230 are slidably connected. One end of the second spring 231 abuts against the side of the connecting rod 322 away from the vertical plate 200. A limiting rod 323 is slidably provided in the rectangular hole 241. A rotating pin 324 is provided above the front end of the limiting rod 323. The rotating pin 324 is in rolling cooperation with the elongated hole 111.

[0048] When the flipping assembly 400 drives the clamping assembly to rotate downwards toward one side of the conveying mechanism 1, the output end of the spreading member 310 pushes the upper end of the rotating rod 321 to rotate toward the vertical plate 200, thereby causing the lower end of the rotating rod 321 to rotate toward the horizontal plate 300. This causes the rotating rod 321 to drive the connecting rod 322 to move along the axis of the reset rod 230, so that the limiting rod 323 moves out of the bearing plate 100 along the rectangular hole 241 toward the horizontal plate 300, thereby causing the rotating pin 324 to move toward one end of the vertical plate 200 along the elongated hole 111. After the limiting rod 323 has completely moved out of the bottom of the bearing plate 100, the bearing plate 100 rotates downwards to a vertical state, and the slide 110 is accommodated in the notch groove 242. When the flipping component 400 drives the clamping component to rotate downward toward one side of the conveying mechanism 1, the support plate 100 remains stationary under the action of the rotating pin 324, thereby preventing the support plate 100 from falling under the sample bottle 2 again when water is poured out of the sample bottle 2, thus preventing water from contaminating the support plate 100.

[0049] After the tilting is completed, the expansion member 310 cancels the thrust on the rotating rod 321. Under the restoring force of the second spring 231, the lower end of the rotating rod 321 rotates towards the vertical plate 200, thereby causing the limiting rod 323 to move back to the bottom of the bearing plate 100.

[0050] Preferably, in order to reduce the resistance when the limit rod 323 is reset, the flipping assembly 400 can be rotated upward in the same direction so that the bearing plate 100 can automatically rotate downward under the action of gravity so that the limit rod 323 can be easily reset.

[0051] Specifically, such as Figure 3 , Figure 5 , Figure 9As shown, the spreading member 310 includes a first cylinder 311, a strip plate 312, and push blocks 313. The first cylinder 311 is located on the side of the horizontal plate 300 away from the vertical plate 200, and the output end of the first cylinder 311 faces the vertical plate 200. The strip plate 312 is arranged along the length direction of the horizontal plate 300 and is parallel to the vertical plate 200. Both ends of the strip plate 312 extend beyond the ends of the horizontal plate 300 by a predetermined length. The push blocks 313 are arranged in an array along the side of the strip plate 312 facing the vertical plate 200, and the number of push blocks 313 is consistent with the number of strip holes 210. The push block 313 includes a triangular block 3131, which is an isosceles triangle structure. The apex of the triangular block 3131 faces one end of a set of clamping plates 220, and the width of the apex of the triangular block 3131 is less than the distance between the ends of the set of clamping plates 220. The horizontal part of the triangular block 3131 faces the strip plate 312. A rectangular block 3132 is provided on the horizontal part of the triangular block 3131. One side of the rectangular block 3132 is connected to the triangular block 3131 and the other side is connected to the strip plate 312. A U-shaped groove 3133 is recessed inward in the middle of the apex of the triangular block, and the opening height of the U-shaped groove 3133 is greater than the outer diameter of the first spring 221.

[0052] In use, the first cylinder 311 is activated, which pushes the strip plate 312 toward the vertical plate 200, so that one end of each set of clamping plates 220 rotates around the pin 223 toward the two ends of the corresponding strip hole 210 under the action of the corresponding triangular block 3131. When the connection between the triangular block 3131 and the rectangular block 3132 contacts the corresponding set of clamping plates 220, one end of the set of clamping plates 220 rotates to the maximum position, and the other end completes clamping.

[0053] At this time, the limiting rod 323 is still located below the bottom of the support plate 100. The first cylinder 311 continues to push the strip plate 312 to move, so that the rectangular block 3132 is completely inserted into one end of the corresponding set of clamping plates 220. Then, the limiting rod 323 is completely removed from the bottom of the support plate 100, and the rotating pin 324 moves to the end of the slide block 110 facing the vertical plate 200. The U-shaped groove 3133 can effectively avoid interference between the triangular block 3131 and the first spring 221 and the guide rod 211 when the triangular block 3131 moves.

[0054] Specifically, such as Figure 10 As shown, the flipping assembly 400 includes a base 410 and a vertical plate 420. The upper end of the vertical plate 420 is connected to a linear mechanism, and the lower end is connected to the base 410. A rack 411 is provided on the base 410. The rack 411 is arranged parallel to one end of the clamping assembly. A connecting shaft 421 is provided in the middle of the vertical plate 420. One end of the connecting shaft 421 is connected to one end of the vertical plate 200, and the other end is provided with a gear 422. The gear 422 meshes with the rack 411. A second cylinder 412 is provided at one end of the rack 411. The second cylinder 412 is located at one end of the base 410.

[0055] In use, the second cylinder 412 is activated, which pushes the rack 411 to move, thereby causing the rack 411 to drive the gear 422 to rotate, and thus the connecting shaft 421 drives the vertical plate 200 to rotate under the action of the gear 422.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
