[0001] This application belongs to the field of packaging box sorting technology, and in particular relates to a sample packaging box delivery system. Background Technology

[0002] To prevent samples to be packaged (such as detectors and calibration devices) from contaminating the testing site during the testing process, such as when some calibration devices for testing liquids leak during testing, classification, transportation, or storage, thus contaminating the testing station, it is necessary to box the samples to be packaged. However, during the boxing process, different sizes of packaging boxes are required due to the different sizes of the samples to be packaged. In the tense boxing operation, due to staff fatigue or uneven distribution of packaging boxes, not only is it easy to waste packaging boxes, but the efficiency of the packaging operation is also low. Summary of the Invention

Detailed Implementation

[0024] To more clearly illustrate the technical solutions of the embodiments of this application, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Please refer to Figures 1 to 8 This application provides a sample packaging box dispensing system, including: a conveying mechanism 10, a size detection mechanism 20, and a packaging box dispensing mechanism 30. The conveying mechanism 10 is used to transport samples to be packaged. The size detection mechanism 20 includes an inclined chute 201, a steering component, a measuring component 203, and a guiding component 204. The feeding end of the inclined chute 201 cooperates with the discharging end of the conveying mechanism 10. The steering component is disposed at the feeding end of the inclined chute 201 and is used to change the sample to be packaged from a vertical state to a horizontal state. The measuring component 203 includes a large telescopic component 2031, a medium telescopic component 2032, and a small telescopic component 2033, which are arranged in a specific order. The large telescopic component 2031, medium telescopic component 2032, and small telescopic component 2033 are all capable of extending and retracting towards the side wall of the inclined chute 201, and are all used to measure the size of the sample to be packaged. The guide component 204 is spaced between the large telescopic component 2031, medium telescopic component 2032, and small telescopic component 2033, and can be flipped to be installed at the bottom of the inclined chute 201. The packaging box dispensing mechanism is equipped with a controller 303, which is connected to the guide component 204. The discharge port of the packaging box dispensing mechanism 30 is connected to the guide component 204 to dispense packaging boxes of different sizes and allow the sample to be packaged to slide into the packaging box.

[0026] To reduce costs and increase efficiency, and to address the low efficiency and high cost (high labor costs) caused by relying on human eyes to identify the size of rectangular or square samples before selecting packaging boxes, the sample packaging box delivery system described above is designed.

[0027] This application sorts and packages rectangular and square samples. When the sample delivery device is set up, the conveying mechanism 10 is mounted on the ground via a support. In actual use, the conveying mechanism 10 can be a conveyor belt. The inclined chute 201 can be a smooth chute, and its width is much greater than the width of the largest sample to be packaged. The steering component uses a disc, wheel, etc., to change the sample from a vertical state (where the smaller cross-sectional area end contacts the conveying mechanism 10) to a horizontal state (where the larger cross-sectional area end contacts the conveying mechanism 10). The measuring component 203 uses a compression spring, spring rod 2034, etc., and the sample pushes the measuring component 203 to move to both sides, thereby activating the corresponding guide component 204 to achieve the classification of samples into large, medium, and small sizes. The minimum spacing of the large telescopic component 2031 is the same as the maximum spacing of the medium telescopic component 2032; the minimum spacing of the medium telescopic component 2032 is the same as the maximum spacing of the small telescopic component 2033. The guide assembly 204 adopts, but is not limited to, solenoid valves, flaps, etc. There are three guide assemblies 204, which are respectively spaced between the large telescopic component 2031, the medium telescopic component 2032 and the small telescopic component 2033.

[0028] Furthermore, the sample to be packaged is driven by the conveying mechanism 10 and uniformly adjusted to a horizontal state by the steering component. Then, it slides along the inclined direction of the inclined chute 201 to the large telescopic component 2031. When the large telescopic component 2031 is extended or retracted by the sample, the guide component 204 correspondingly set between the large telescopic component 2031 and the medium telescopic component 2032 opens and flips downward. The sample to be packaged falls from the guide component 204 into the packaging box dispensed by the packaging box dispensing mechanism 30. When the size of the sample to be packaged is smaller than the minimum spacing of the large telescopic component 2031, the sample to be packaged slides past the large telescopic component 2031 and the corresponding guide component 204, slides to the medium telescopic component 2032, and pushes the medium telescopic component. When component 2032 extends and retracts to both sides, it simultaneously causes the guide component 204 located between the medium-sized telescopic component 2032 and the small telescopic component 2033 to flip downwards, causing the sample to be packaged to fall from the guide component 204 into the packaging box dispensed by the packaging box dispensing mechanism 30. When the size of the sample to be packaged is smaller than the minimum spacing of the medium-sized telescopic component 2032, the sample to be packaged slides past the medium-sized telescopic component 2032 and the corresponding guide component 204, slides to the small telescopic component 2033 and pushes the small telescopic component 2033 to extend and retract to both sides, simultaneously causing the guide component 204 located behind the small telescopic component 2033 to flip downwards, causing the sample to be packaged to fall from the guide component 204 into the packaging box dispensed by the packaging box dispensing mechanism 30.

[0029] The technical solution of the sample packaging box delivery system adopted in this application can achieve the following beneficial effects: The size of the sample to be packaged is obtained by the size detection mechanism 20, which drives the corresponding guide component 204 to open, allowing the sample to slide down. Simultaneously, the packaging box dispensing mechanism 30 dispenses a packaging box of the corresponding size. The sample slides into the packaging box, making the operation simple and convenient. This eliminates the need for manual observation of sample size to select a suitable packaging box, improving work efficiency and avoiding situations where the sample is too small for the packaging box or vice versa, thus preventing packaging box waste and solving the problem of matching packaging boxes to the sample. Furthermore, selecting packaging boxes based on sample size also improves the utilization rate of sample storage space, preventing small samples from occupying large storage areas.

[0030] Based on the above embodiments, the steering component includes a rotating shaft 2021 rotatably connected to the inclined slide 201. The two ends of the rotating shaft 2021 are respectively connected to the opposite sides of the inclined slide 201 and can rotate in a preset direction to push the sample to be packaged from a vertical state to a horizontal state.

[0031] The height of the rotating shaft 2021 is not greater than the minimum spacing of the large telescopic component 2031. When the sample to be packaged is in a vertical state, the sample to be packaged is driven forward by the conveying mechanism 10. The upper half of the sample to be packaged contacts the rotating shaft 2021. Under the drive of the conveying mechanism 10, the lower part of the sample to be packaged continues to move, and the upper half flips backward, thereby changing it from a vertical state to a horizontal state. Furthermore, in order to prevent the sample to be packaged from accumulating at the rotating shaft 2021, several push plates are set on the conveying mechanism 10. The push plates drive the lower part of the sample to be packaged to continue to move, thereby solving the accumulation problem.

[0032] In another embodiment of this application, to prevent the sample to be packaged from being unable to slide and remaining in the inclined chute 201, a transport component 2011 is provided at the bottom of the inclined chute 201, and the transport component 2011 is located between adjacent guide components 204 to drive the sample to be packaged to move. The transport component 2011 is, but is not limited to, a conveyor belt, with protrusions on the conveyor belt to increase friction, etc. Three transport components 2011 are provided, respectively located between two adjacent guide components 204 (the first transport component 2011 is located between the rotating shaft 2021 and the first guide component 204). When the sample to be packaged passes through the rotating shaft 2021, it is driven by the transport component 2011 to move through the large telescopic component 2031, and then through the guide component 204. The second transport component 2011 drives it to continue moving until one of the guide components 204 is opened. The operation is simple and convenient, and solves the problem of the sample to be packaged remaining in the inclined chute 201 and unable to move.

[0033] Based on the above scheme, the large telescopic component 2031 includes a spring rod 2034 and a push block 2035. The spring rod 2034 is symmetrically arranged on both sides of the inclined slide 201 and can extend and retract in a direction perpendicular to the side wall of the inclined slide 201. One end of the push block 2035 is connected to the spring rod 2034, and the other end is provided with a plurality of rolling balls 2036.

[0034] Large telescopic component 2031, medium telescopic component 2032, and small telescopic component 2033 all use a spring rod 2034 (at least one spring rod 2034 is provided according to the length of the push block 2035) and a push block 2035. The length of the spring rod 2034 in the large telescopic component 2031, medium telescopic component 2032, and small telescopic component 2033 decreases sequentially. The push block 2035 is a right-angled trapezoidal shape block, and several rolling balls 2036 are provided on the upper bottom and inclined surface of the push block 2035. The lower bottom of the push block 2035 is connected to the spring rod 2034. The spring rod 2034 adopts a structure of sliding rod and spring cooperation. The sliding rod of the spring rod 2034 is slidably set on the side wall of the inclined groove 201. One end of the spring is fixed to the inner wall of the inclined slide 201, and the other end is opened at one end of the sliding rod through a limiting post (or it can be directly fixed to the bottom of the push block 2035); wherein, the inclined surface of the push block 2035 faces the end of the rotating shaft 2021; when the sample to be packaged contacts the ball 2036 on the inclined surface of the push block 2035, the sample to be packaged, driven by the transport component 2011, drives the push block 2035 to move to both sides of the inclined slide 201, and at the same time, the sliding rod of the spring rod 2034 slides and compresses the spring of the spring rod 2034. When the sample to be packaged contacts the top bottom of the push block 2035, the transport component 2011 drives it to continue moving, and at the same time, the ball 2036 rotates, making one end of the sample to be packaged smoother.

[0035] Based on the above scheme, the guide assembly 204 includes an electromagnetic flap 2041, an electromagnetic switch 2042, and a blocking plate 2043. One end of the blocking plate 2043 is connected to the end of the spring rod 2034 away from the push block 2035 and is located between the electromagnetic switches 2042, for controlling the closing and opening of the electromagnetic switches 2042. The electromagnetic switch 2042 is connected to one side of the inclined slide 201 and is electrically connected to the electromagnetic flap 2041. The electromagnetic switch 2042 is electrically connected to the controller 303.

[0036] A blocking plate 2043 is provided at the end of the sliding rod of the spring rod 2034 away from the push block 2035. The blocking plate 2043 is made of insulating material. The electromagnetic flip plate 2041 is hinged to the bottom of the inclined slide chute 201 and is connected to a guide channel. The outlet of the guide channel is connected to the outlet of the packaging box delivery mechanism 30. In the initial state, the electromagnetic flip plate 2041 is closed and the electromagnetic switch 2042 is in the closed state. When the sample to be packaged moves the sliding rod of the corresponding size of the spring rod 2034 to both sides, the blocking plate 2043 moves and extends between the electromagnetic switches 2042, causing the electromagnetic switches 2042 to open. The electromagnetic flip plate 2041 loses its electromagnetic field and flips downward to open. The sample to be packaged falls from the open part of the electromagnetic flip plate 2041 into the guide channel. The sliding rod drives the blocking plate 2043 to move, which solves the problem of inconvenience of manual control and makes the operation simpler. Furthermore, after the sample to be packaged leaves the range of the transport component 2011, it enters the range of the electromagnetic flap 2041. The electromagnetic flap 2041 has a smooth surface and the inclined slide 201 is inclined, so that the sample to be packaged can slide over the electromagnetic flap 2041 by its own weight.

[0037] To prevent the electromagnetic flap 2041 from closing before the sample to be packaged falls into the opening position, the ends of all sliding rods are connected together by a connecting plate, and a blocking plate 2043 is set at the end of the connecting plate near the electromagnetic flap 2041; at the same time, the right-angled side of the pushing block 2035 is flush with one end of the electromagnetic flap 2041.

[0038] To enable the guide assembly 204 to be linked with the packaging box dispensing mechanism 30, the controller 303 on the packaging box dispensing mechanism 30 is equipped with three trigger switches: large, medium, and small. When the electromagnetic flap 2041 near the rotating shaft 2021 is flipped, the controller 303 is triggered by the large switch; when the electromagnetic flap 2041 away from the rotating shaft 2021 is flipped, the controller 303 is triggered by the small switch. When the controller 303 is triggered by the large switch, the packaging box dispensing mechanism 30 dispenses a large-sized packaging box; when the controller 303 is triggered by the small switch, the packaging box dispensing mechanism 30 dispenses a small-sized packaging box. This makes the operation simpler and more convenient, and ensures that small samples to be packaged fall into small-sized packaging boxes along the guide channel, and the same applies to other samples.

[0039] Furthermore, to prevent the electromagnetic flap 2041 from being difficult to reset after opening, a time-delay motor is provided at one end of the hinge shaft of the electromagnetic flap 2041. The trigger switch of the time-delay motor is similar to that of the electromagnetic switch 2042. The fixed end of the trigger switch is located on one side of the inclined slide 201 and on the opposite side of the electromagnetic switch 2042. The moving end of the trigger switch is connected to the end of the sliding rod away from the push block 2035. When the spring rod 2034 slides to both sides, the spring rod 2034 on one side drives the blocking plate 2043 to control the flipping of the electromagnetic flap 2041. The spring rod 2034 on the other side drives the moving end of the trigger switch to contact the fixed end, thereby turning on the time-delay motor. The time-delay motor turns on after a preset time, driving the hinge shaft of the electromagnetic flap 2041 to rotate, driving the electromagnetic flap 2041 to reset, thereby closing it again. The time-delay motor and the electromagnetic flap 2041 are both electrically connected to the trigger switch and the electromagnetic switch 2042 respectively.

[0040] Furthermore, the electromagnetic switch 2042 includes a main block and a secondary block. The main block is connected to the live wire, and the secondary block has a groove. A spring block (the spring block is a right trapezoid with its inclined surface facing the side wall of the inclined groove 201) is placed in the groove. The spring block can move up and down vertically and is connected to the neutral wire. The blocking plate 2043 moves horizontally under the action of the spring rod 2034, pushing the inclined surface of the spring block downward along the side wall of the groove, causing the upper surface of the spring block to separate from the main block, thereby disconnecting the circuit. When the blocking plate 2043 is reset under the action of the spring rod 2034, the spring block loses pressure, resets along the side wall of the groove, and the upper surface of the spring block contacts the main block, thereby connecting the circuit.

[0041] In another embodiment of this application, the packaging box dispensing mechanism 30 includes a fixed base 301 and several packaging box stacking slots 302 of different sizes arranged adjacent to the fixed base 301. Several packaging boxes are stacked in the packaging box stacking slots 302, and a packaging box dispensing component 304 is provided at the lower end of the packaging box stacking slots 302. The controller 303 is electrically connected to the packaging box dispensing component 304 and the guide component 204. The controller 303 is used to control the operation of the packaging box dispensing component 304 based on the open position of the guide component 204.

[0042] The fixed seat 301 on the packaging box dispensing mechanism 30 is used to install the controller 303 and the packaging box stacking slots 302 of different sizes (for storing packaging boxes of different sizes), and the packaging box stacking slots 302 are set vertically on the fixed seat 301.

[0043] In the above scheme, the packaging box stacking slot 302 includes a large sample packaging box stacking slot 3021, a medium sample packaging box stacking slot 3022, and a small sample packaging box stacking slot 3023. The large sample packaging box stacking slot 3021, the medium sample packaging box stacking slot 3022, and the small sample packaging box stacking slot 3023 have the same structure and are stacked with packaging boxes of different sizes respectively.

[0044] In use, the packaging box stacking slot 302 is divided into large, medium and small packaging box stacking slots 302, which are used to place packaging boxes of different sizes. It should be noted that the large sample packaging box stacking slot 3021, the medium sample packaging box stacking slot 3022 and the small sample packaging box stacking slot 3023 have the same structure, only different sizes.

[0045] Specifically, the cross-sectional shape of the packaging boxes is an inverted trapezoid. In use, if the packaging box sizes are: Specification 1: 60cm*40cm*20cm; Specification 2: 40cm*30cm*15cm; Specification 3: 30cm*20cm*10cm; and the sample to be packaged is 25cm*30cm*10cm, then a Specification 2 packaging box should be used, as the sample size falls within the usable size range of the Specification 2 packaging box.

[0046] To facilitate the placement of packaging boxes, the cross-section of the packaging boxes is inverted trapezoidal, and several packaging boxes of the same size and volume are stacked one on top of the other in the corresponding sample packaging box stacking slot 302. At this time, the packaging boxes in the packaging box stacking slot 302 present a front view where the length of the upper base is greater than the length of the lower base.

[0047] Furthermore, the packaging box dispensing assembly 304 includes a pre-tensioning rod 3041 and a pre-tensioning spring 3042 symmetrically distributed on both sides of the lower end of the packaging box stacking slot 302. One end of the pre-tensioning rod 3041 is hinged to the outer wall of the packaging box stacking slot 302, and the other end is driven to be equipped with a roller 3043. The two ends of the pre-tensioning spring 3042 are respectively connected to the packaging box stacking slot 302 and the pre-tensioning rod 3041, so that the roller 3043 abuts against the two sides of the packaging box. The shaft of the roller 3043 is driven to be connected to a hub motor 3044, and the hub motor 3044 is electrically connected to the controller 303.

[0048] The pre-tensioning rod 3041 is hinged to the side of the packaging box stacking slot 302. When the packaging box dispensing component 304 needs to dispense a packaging box, the controller 303 controls the hub motor 3044 of the packaging box dispensing component 304 corresponding to the sample size to start, causing the roller 3043 to rotate. At this time, the roller 3043 abuts against the bottom packaging box, and the rotation directions of the pair of rollers 3043 are opposite, that is, the left roller 3043 rotates clockwise and the right roller 3043 rotates counterclockwise. Under this rotation direction, the rollers 3043 generate downward friction on the packaging box. The force causes the bottommost packaging box to fall out of the packaging box stacking slot 302. During the falling process, the distance between the two pre-tensioning rods 3041 increases, and the pre-tensioning spring 3042 is stretched. After a packaging box is dropped, the controller 303 controls the hub motor 3044 to stop rotating, and the distance between the two pre-tensioning rods 3041 returns to the original spacing. During this process, the pre-tensioning spring 3042 resets, providing an inward tightening force for the pre-tensioning rods 3041 to reset, so that the roller 3043 abuts against the new packaging box located at the bottom of the packaging box stacking slot 302.

[0049] The hub motor 3044 is driven to rotate on the shaft 2021 of the roller 3043. The coordination between the hub motor 3044 and the roller 3043 is a conventional technique and will not be described in detail here.

[0050] Furthermore, a shock-absorbing rod 3045 is provided horizontally at the end of the pretension rod 3041 away from the packaging box stacking slot 302, and a roller 3043 is provided rotatably at the end of the shock-absorbing rod 3045 away from the pretension rod 3041.

[0051] To avoid the impact of roller 3043 on the packaging box during the reset process, a shock-absorbing rod 3045 is provided between roller 3043 and pretension rod 3041 to reduce the impact of roller 3043 on the packaging box and prevent the packaging box from deforming. At the same time, the shock-absorbing rod 3045 can increase the efficiency of the tightening action of roller 3043, so that roller 3043 can almost always be in contact with the side of the packaging box and play a role in fixing the bottom of the packaging box, preventing the packaging box from accidentally falling off.

[0052] Based on the above scheme, the fixed base 301 is provided with several pairs of slide rails along the direction of gravity, and the packaging box stacking slot 302 is slidably connected to the slide rails.

[0053] The heights of the large, medium, and small packaging boxes are inconsistent, resulting in varying distances from the box receiving surface below the box stacking slot 302. Larger boxes are closer to the receiving surface, while smaller boxes are farther away. To prevent boxes from blocking the outlet of the stacking slot 302 due to an improper distance between it and the receiving surface, a slide rail is installed on the fixed base 301. The box stacking slot 302 can be connected to the slide rail (with threaded holes) via bolts to adjust the distance between it and the receiving surface.
