[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0032] Reference Figures 1 to 12 The present invention proposes an automatic filling machine for flower preservation tubes 2, comprising a frame 1, on which are provided a material bin 7, a feeding and pipe laying mechanism 3, a multi-channel feeding mechanism 4, a feeding and taking mechanism 5, a tube clamping mechanism 6, and a filling mechanism.

[0033] The multi-channel feeding mechanism 4 includes a feeding frame 41 and a feeding power device 42. The feeding frame 41 is provided with a plurality of feeding troughs 411 arranged in a front-to-back direction. The top opening width of the feeding trough 411 is larger than the diameter of the lower end of the tube neck 24, but smaller than the diameter of the upper end of the tube neck 24. Therefore, it can be used to support the tube neck 24 of the fresh-keeping tube 2 so that the tube head 22 of the fresh-keeping tube 2 faces upward. The feeding power device 42 adopts a linear vibrator, which can apply vibration to the feeding frame 41 to transport the fresh-keeping tube 2 in the feeding trough 411 forward. A limiting structure is provided at the front end of the feeding trough 411. The limiting structure is preferably fixed to a plate at the front end of the feeding trough 411 to block the fresh-keeping tube 2 that has moved to the front end of the feeding trough 411.

[0034] The feeding and pipe laying mechanism 3 includes a pipe laying plate 31 and a feeding device capable of conveying the fresh-keeping tubes 2 in the silo 7 to the pipe laying plate 31. The pipe laying plate 31 is provided with a plurality of pipe laying grooves 311 arranged in a front-to-back direction in parallel, and the front end of each pipe laying groove 311 is located above the corresponding feeding groove 411. Preferably, the cross section of the pipe laying plate 31 is wavy, and the troughs on the pipe laying plate 31 constitute the pipe laying grooves 311. The crests and troughs of the pipe laying plate 31 can be sharp angles, in which case the cross-sectional shape of the pipe laying plate 31 is sharp and wavy; the crests and troughs can also be arcs with a gentle transition similar to a sine curve.

[0035] The feeding mechanism 5 is used to grab the preservation tubes 2 at the front end of all the feeding troughs 411 and transport the preservation tubes 2 to the tube clamping mechanism 6. The perfusion mechanism includes a perfusion tube assembly 81 located above the tube clamping mechanism 6 and a perfusion driver 82 that can drive the perfusion tube assembly 81 to move up and down.

[0036] The perfusion pipe assembly 81 is connected to the perfusion pump through a pipe fitting. After the perfusion pipe assembly 81 is inserted downward into the preservation tube 2, the perfusion pump can be turned on. The perfusion pump extracts the nutrient solution or water in the container, and the nutrient solution water can be injected into the preservation tube 2. After the perfusion is completed, the perfusion pump is turned off, and the perfusion pipe assembly 81 is pulled out upward. When the perfused liquid is tap water, the following design can also be adopted. The perfusion pipe assembly 81 is connected to the faucet through a pipe fitting, and an electric valve or a solenoid valve is provided on the pipe fitting. After the perfusion pipe assembly 81 is inserted downward into the preservation tube 2, the solenoid valve or the electric valve can be turned on to inject tap water into the preservation tube 2.

[0037] The number of the pipe laying slots 311 and the material feeding slots 411 are equal, and their positions correspond one to one. The number of the two can be 3, 4, 5, 6, and so on.

[0038] The feeding device includes a conveyor line, one end of which is located in the silo 7, and the other end of which is located above the tube plate 31. Preferably, the silo 7 is located behind the material plate, and the conveyor line is an inclined belt conveyor line 32, and a material blocking strip 322 is provided on the conveyor belt 321 of the belt conveyor line 32. The conveyor belt 321 is used to take the fresh-keeping tube 2 out of the silo 7, and then lift the upper end of the conveyor belt 321 upwardly. At this time, the workpiece is located above the tube plate 31, and falls on the tube plate 31 after falling from the conveyor belt 321.

[0039] The tube plate 31 is preferably arranged in the following manner: the tube plate 31 is arranged horizontally in the front-to-back direction, and the frame 1 is also provided with a linear vibrator capable of applying vibration to the tube plate 31 to transport the fresh-keeping tubes 2 thereon forward.

[0040] In the above solution, the output process of the fresh-keeping tube 2 is as follows: First, under the power of the belt conveyor 32, the fresh-keeping tube 2 in the silo 7 is gradually lifted to the highest point at the front end of the conveyor belt 321; then it falls onto the pipe-laying plate 31 and randomly falls into each pipe-laying groove 311 of the pipe-laying plate 31; next, under the vibration of the linear vibrator, the fresh-keeping tube 2 on the pipe-laying plate 31 is moved forward and falls downward into the corresponding feeding groove 411, and finally is conveyed to the front end of the feeding groove 411 under the drive of the feeding power device 42. The advantage of this solution is that after the fresh-keeping tube 2 in a silo 7 is output, the insurance tubes can be automatically distributed in multiple parallel cloth grooves, and then these fresh-keeping tubes 2 slowly fall into the corresponding feeding grooves 411. Only one power source is required to achieve multi-channel feeding, and the working efficiency is high; in addition, no matter which direction the head of the fresh-keeping tube 2 originally faces, it is in the state with the head facing up after falling into the corresponding feeding groove 411, which is beneficial to subsequent automatic filling.

[0041] In some solutions of the present invention, the above feeding and pipe-laying mechanism 3 can also adopt other structural forms. For example, the pipe-laying plate 31 is changed to the following arrangement: the pipe-laying plate 31 is arranged obliquely in the front-rear direction, with the rear end of the pipe-laying plate 31 being the highest point. After the fresh-keeping tube 2 falls into the pipe-laying groove 311 of the pipe-laying plate 31, it slides forward under the action of gravity, and the linear vibrator that applies vibration to the pipe-laying plate 31 can be cancelled in this solution. For another example, a chain plate conveyor is used to replace the above belt conveyor 32, and a supporting block capable of supporting the fresh-keeping tube 2 is arranged on a part of the chain plate to replace the baffle strip 322 on the above conveyor belt 321.

[0042] Furthermore, the frame 1 is provided with a rotating material stop mechanism 9, which includes a material stop shaft 91 rotatably mounted behind the pipe layout plate 31, a plurality of material stop units 92 spaced apart on the material stop shaft 91, and a material stop driver 93 capable of driving the material stop shaft 91 and all the material stop units 92 to rotate together, and the material stop driver 93 is preferably a motor. The material stop unit 92 includes at least two material stop members 921, and the number of the material stop members 921 in the same material stop unit 92 is generally 2-5, such as 3 or 4, and all the material stop members 921 are radially arranged with the material stop shaft 91 as the center, and a material transfer space is formed between any two material stop units 92, and the rear port of each pipe layout groove 311 faces a material transfer space. The material stop member 921 can be a rigid material or an elastic material, and a rubber strip with a certain elasticity is the best. Sometimes, the fresh-keeping tubes 2 are stacked on the tube plate 31. At this time, since the fresh-keeping tubes 2 on the lower layer have already occupied the tube grooves 311 on the tube plate 31, the fresh-keeping tubes 2 on the upper layer are likely to be located in the area between the two tube grooves 311. At this time, if they are allowed to fall directly onto the feed rack 41, they are likely to fall between the two feed grooves 411 and then be stuck between the corresponding two rows of fresh-keeping tubes 2. In the above scheme, the fresh-keeping tubes 2 located in the area between the two tube grooves 311 can be pushed back by driving the blocking shaft 91 to rotate each blocking member 921, so that the fresh-keeping tubes 2 on the tube plate 31 can only fall forward along the tube grooves 311 into the corresponding feed grooves 411. Compared with the fixed guide structure used in the tube plate 31 and the feed rack 41, it can avoid a large number of fresh-keeping tubes 2 from accumulating at the front end of the tube plate 31 and causing blockage.

[0043] Furthermore, the rack 1 is provided with a sensor 43 capable of counting the number of fresh-keeping tubes 2 in each feeding slot 411, and the rack 1 is also provided with a plurality of limit mechanisms corresponding to the pipe-laying slots 311. The bottom of each pipe-laying slot 311 is provided with a perforation 313, and the limit mechanism includes a limit rod 33 capable of extending upward into the pipe-laying slot 311 through the perforation 313, and a limit driver 34 capable of driving the limit rod 33 to move up and down. The limit driver 34 can be a cylinder, an oil cylinder or other device, among which a cylinder is the best. The above-mentioned sensor 43 can be a photoelectric sensor, or a contact sensor 43, etc. When the sensor 43 detects that the fresh-keeping tubes 2 in a feeding trough 411 are full or have reached the set number, the signal can be fed back to the central control system, and then the central control system can give an execution instruction to make the limit driver 34 work, drive the corresponding limit rod 33 to extend upward into the corresponding pipe distribution groove 311, and temporarily block the subsequent fresh-keeping tubes 2 in the pipe distribution groove 311. After the front-end fresh-keeping tube 2 in the feeding trough 411 is taken away, the corresponding limit rod 33 falls to a position below the bottom surface of the feeding trough 411 to continue to replenish the corresponding feeding trough 411.

[0044] Reference Figure 3 , Figures 8 to 11 The feeding mechanism 5 includes a plurality of pipe clamps 51 arranged at intervals along the left-right direction, a transport power mechanism capable of driving all the pipe clamps 51 to move in the front-to-back direction and the up-down direction, and each pipe clamp 51 corresponds to a feed trough 411. A transport bracket 11 is provided on the frame 1, and the transport power mechanism includes a horizontal transport bracket 52 that can move forward and backward relative to the transport bracket 11, a horizontal driver 53 that can drive the horizontal transport bracket 52 to move forward and backward relative to the transport bracket 11, a lifting transport bracket 54 that can move up and down relative to the horizontal transport bracket 52, and a lifting driver 55 that can drive the lifting transport bracket 54 to move up and down relative to the horizontal transport bracket 52. All the pipe clamps 51 are fixed on the lifting transport bracket 54. The lifting driver 55 and the horizontal driver 53 can be motors, cylinders, oil cylinders and other devices, among which cylinders are the best. The above-mentioned pipe clamps 51 are preferably pneumatic grippers.

[0045] The horizontal transport rack 52 is provided with a top support plate 101 located above the feeding rack 41. The bottom surface of the top support plate 101 can abut against the tops of all the fresh-keeping tubes 2 on the lifting transport rack 54 so that all the fresh-keeping tubes 2 are aligned in the vertical direction. The transport bracket 11 is provided with a side support plate 102 located above the feeding rack 41 and a secondary shaping driver 109 capable of driving the side support plate 102 to move forward and backward. The secondary shaping driver 109 is preferably a cylinder. When the side support plate 102 moves forward, it presses all the fresh-keeping tubes 2 on the lifting transport rack 54 so that all the fresh-keeping tubes 2 are aligned in the front-to-back direction.

[0046] The frame 1 is provided with a tube bottom support plate 104 located in front of the feeding frame 41 and a feeding chute 105 located in front of the tube bottom support plate 104. The perfusion tube assembly 81 is located above the feeding chute 105 and higher than the tube bottom support plate 104. The tube clamping mechanism 6 includes a transfer frame 61, a transfer driver 62 capable of driving the transfer frame 61 to move, and an openable and closable workpiece clamp 63 disposed on the transfer frame 61 and located between the perfusion tube assembly 81 and the feeding chute 105. When the transfer frame 61 moves backward, the workpiece clamp 63 moves to the top of the tube bottom support plate 104. The transfer driver 62 can be a cylinder, a motor, an oil cylinder or the like, among which a cylinder is the best. When the workpiece clamp 63 is opened above the feeding chute 105, the fresh-keeping tube 2 on it falls into the feeding chute 105.

[0047] In the above scheme, the method of sending the fresh-keeping tube 2 on the feeding rack 41 to the working position of the perfusion tube assembly 81 for perfusion is as follows:

[0048] Step 1: Grab the fresh-keeping tubes 2. First, the lifting and transporting frame 54 lowers all the tube clamps 51 to a suitable position, then the horizontal driver 53 drives all the tube clamps 51 to move backwards together and clamp the fresh-keeping tubes 2 in the front row on the feeding frame 41; finally, the lifting and transporting frame 54 is driven upward by the lifting and transporting frame 55, and the fresh-keeping tubes 2 in the front row can be taken out from the feeding slot 411 respectively, and the grabbing is completed. At this time, the state of the feeding mechanism 5 is as follows: Figure 8 shown.

[0049] Step 2: Shaping and positioning. Under the vibration of the linear vibrator, many of the fresh-keeping tubes 2 in the front row on the feeding rack 41 are skewed to a certain extent, such as 5 degrees to the left, 7 degrees to the right and rear, etc. The shaping process is as follows: first, the feeding mechanism 5 lifts the grabbed fresh-keeping tubes 2 upward until the tube covers 23 of all the fresh-keeping tubes 2 are against the top support plate 101; then, the secondary shaping driver 109 pushes the side support plate 102 forward to align all the fresh-keeping tubes 2 in the front-to-back direction, and the shaping and positioning is completed. The state at this time is as follows: Fig. 9 In order to improve the shaping and positioning effect, an escape space is provided between the upper edge of the side support plate 102 and the lower surface of the top support plate 101 for the edge of the pipe cover 23 to be embedded therein.

[0050] Step 3: Send the fresh-keeping tube 2 to the working position of the workpiece clamp 63. During the process of the first and second steps above, the workpiece clamp 63 is moved to the top of the tube bottom support plate 104 and switched to the open state under the power of the transfer driver 62. After the fresh-keeping tube 2 is shaped and positioned, the fresh-keeping tube 2 is placed on the tube bottom support plate 104 by the feeding mechanism 5. The state at this time is as follows: Fig.10 As shown, the workpiece clamp 63 finally clamps the fresh-keeping tube 2.

[0051] Step 4: Filling. Then, the transfer driver 62 drives the transfer rack 61 to move forward, so that all the fresh-keeping tubes 2 move between the filling tube assembly 81 and the feeding chute 105. The state at this time is as follows: Fig.11 As shown, the filling pipe assembly 81 then moves downward, passes through the cross hole on the pipe cover 23 and extends into the fresh-keeping tube 2, and then injects nutrient solution or water into the fresh-keeping tube 2. After filling, the filling pipe assembly 81 withdraws upward, and then the workpiece clamp 63 opens, so that the filled fresh-keeping tube 2 can fall into the feeding trough 105 below.

[0052] Referring to 10, in a preferred embodiment of the present invention, the workpiece clamp 63 includes a front clamping plate 631, a rear clamping plate 632 located behind the front clamping plate 631, a first tube clamping driver 633 capable of driving the front clamping plate 631 to move forward and backward on the intermediate transfer frame 61, and a second tube clamping driver 634 capable of driving the rear clamping plate 632 to move forward and backward on the intermediate transfer frame 61, and the rear side edge of the front clamping plate 631 and the front side edge of the rear clamping plate 632 are both provided with clamping grooves 635.

[0053] Furthermore, the perfusion tube assembly 81 includes a liquid injection tube 811 for outputting liquid and a ventilation tube 812 fixed on the liquid injection tube 811. The ventilation tube 812 is parallel to the liquid injection tube 811 and the two are in close contact. The lower end of the ventilation tube 812 is flush with the lower end of the liquid injection tube 811. The tube cover 23 of the common preservation tube 2 on the market is made of soft rubber or plastic material. The flower insertion hole 231 in the tube cover 23 is a cross hole. By adding a ventilation tube 812 to the liquid injection tube 811, it is convenient to discharge the air in the preservation tube 2 during the perfusion process.

[0054] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
