[0037] In conjunction with Figures 1 to 4As shown, the embryo feeding device provided in the embodiment is used to put the bottle embryo 20 into the entrance of the embryo slide 10, so as to reduce the labor intensity and labor cost in the production of large-volume bottle body and improve the embryo feeding efficiency. Specifically, the embryo feeding device comprises a feeding mechanism 100 and an embryo feeding mechanism 200. The feeding mechanism 100 comprises a conveying belt 110 and a placing assembly 120. The conveying belt 110 is arranged at one side of the entrance end of the embryo slide 10. The placing assembly 120 is movably arranged on the conveying belt 110, and the placing assembly 120 comprises a plurality of positioning columns 121, each of which allows the bottle embryo 20 to be inserted. The embryo feeding mechanism 200 comprises a base 210, an embryo feeding assembly 220 and a grabbing assembly 230. The base 210 is arranged between the entrance end of the embryo slide 10 and the conveying belt 110. The embryo feeding assembly 220 is movably arranged on the base 210. The grabbing assembly 230 is drivingly arranged on the embryo feeding assembly 220. After the grabbing assembly 230 grabs the bottle embryo 20 inserted on the positioning columns 121, the embryo feeding assembly 220 can drive the grabbing assembly 230 to put the grabbed bottle embryo 20 into the entrance of the embryo slide 10.

[0038] Since the feeding mechanism 100 is arranged at one side of the entrance end of the embryo slide 10, and the embryo feeding mechanism 200 is arranged between the embryo slide 10 and the feeding mechanism 100. Therefore, in the process of feeding the large-volume bottle embryo 20 into the embryo slide 10, the operator first inserts the bottle embryo 20 into the corresponding positioning column 121 one by one, and then the conveying belt 110 conveys the placing assembly 120 to the embryo feeding mechanism 200. The grabbing assembly 230 grabs the bottle embryo 20 on the placing assembly 120. The embryo feeding assembly 220 drives the grabbing assembly 230 to move and put the grabbed bottle embryo 20 into the entrance of the embryo slide 10, thereby completing a feeding process. In the whole process, only the operator needs to manually insert the bottle embryo 20 into the corresponding positioning column 121. One operator can complete the feeding process, thereby saving labor and reducing labor cost. Since the bottle embryo 20 is put into the entrance of the embryo slide 10 by means of the embryo feeding mechanism 200, the feeding efficiency can be improved compared with manual feeding.

[0039] Preferably, the embryo feeding assembly 220 comprises a first mechanical arm 221, a second mechanical arm 222, a third mechanical arm 223 and a connecting piece 224. The connecting piece 224 is rotationally arranged on the base 210 along the A direction. The first end of the first mechanical arm 221 is rotationally arranged on the connecting piece 224 along the B direction. The first end of the second mechanical arm 222 is rotationally arranged on the second end of the first mechanical arm 221 along the B direction. The first end of the third mechanical arm 223 is rotationally arranged on the second end of the second mechanical arm 222 along the B direction. The grabbing assembly 230 is connected to the second end of the third mechanical arm 223 and can rotate around the axis of the third mechanical arm 223.

[0040] Specifically combined Figure 2As shown, when the bottle embryo 20 is placed on the embryo slide 10, the conveying belt 110 conveys the bottle embryo 20 to the embryo placing mechanism 200, the connecting member 224 rotates relative to the base 210 to the direction close to the conveying belt 110, and through the cooperation of the mechanical arms, the grabbing assembly 230 is located above the bottle embryo 20, and then the grabbing assembly 230 grabs the bottle embryo 20 from the bottle bottom; the connecting member 224 rotates relative to the base 210 to the direction close to the embryo slide 10, and through the cooperation of the mechanical arms, the grabbed bottle embryo 20 is brought to the entrance of the embryo slide 10, and then the third mechanical arm 223 rotates 180° upward, so that the bottle mouth of the grabbed bottle embryo 20 corresponds to the entrance of the embryo slide 10, so that after the bottle embryo 20 is placed in the embryo slide 10, the bottle mouth of the bottle embryo 20 is in sliding cooperation with the embryo slide 10, which facilitates the sliding of the bottle embryo 20 in the embryo slide 10, thereby improving the embryo placing effect.

[0041] Preferably, the grabbing assembly 230 comprises a grabbing power member 231 and two clamping plates 232, the grabbing power member 231 is movably arranged on the embryo placing assembly 220, and the two clamping plates 232 are both drivingly connected to the grabbing power member 231, and the two clamping plates 232 are arranged in parallel and spaced apart relative to each other, and the opposite sides of the two clamping plates 232 are both provided with clamping curved surfaces, and the two clamping curved surfaces cooperate to form a clamping space capable of grabbing the bottle embryo 20.

[0042] Specifically combined Figures 1 to 3 As shown, the two clamping plates 232 are driven by the grabbing power member 231 to move closer to or away from each other to realize grabbing and placing of the bottle embryo 20. By arranging clamping curved surfaces on the sides of the two clamping plates 232 that move closer to each other, the two clamping plates 232 are ensured to be more closely attached to the outer wall of the bottle embryo 20 during the grabbing process, thereby ensuring the clamping effect and reducing the probability of causing damage to the grabbed bottle embryo 20 during the grabbing process. In order to improve the convenience and strength of the connection between the two clamping plates 232, the two clamping plates 232 are respectively drivingly connected to the grabbing power member 231 through corresponding connecting plates 233. The grabbing power member 231 is arranged according to the prior art, which is not limited here. In some other embodiments, in order to further reduce the probability of damage to the grabbed bottle, a flexible member such as a silica gel member, a rubber member, or a cotton cloth is arranged on the corresponding clamping curved surface.

[0043] Preferably, the two clamping plates 232 are both arranged as long strip plates, and a plurality of clamping curved surfaces are arranged on the two clamping plates 232 in the extension direction of the clamping plates 232, and each two opposite clamping curved surfaces cooperate to form a clamping space. In this way, the grabbing assembly 230 can grab a plurality of bottle embryos 20 in one grabbing process, and the embryo placing efficiency is further improved by completing the embryo placing process of multiple bottle embryos 20. In this embodiment, the clamping space in the grabbing assembly 230 is provided with four clamping spaces, and in other embodiments, the number of clamping spaces can be increased or decreased as needed, which is not limited here.

[0044] Preferably, the storage assembly 120 further comprises a storage tray 122, the plurality of positioning columns 121 are fixedly arranged in an array on the storage tray 122, and the end of each positioning column 121 away from the storage tray 122 is arranged as a tapered guide portion 1211.

[0045] In combination Figure 1 and Figure 4 As shown in FIG. 2, in order to further improve the convenience and efficiency of the bottle embryo 20, the plurality of positioning columns 121 are fixedly arranged in a rectangular array on the storage tray 122, and the size of the rectangular array corresponds to the number of the arrangement of the clamping spaces in the gripping assembly 230. By arranging the end of the positioning column 121 away from the storage tray 122 as a tapered guide portion 1211, when the bottle mouth of the bottle embryo 20 is inserted into the corresponding positioning column 121, the tapered guide portion 1211 plays a guiding role in insertion, so as to further improve the convenience of placing the bottle embryo 20 on the storage assembly 120. In some other embodiments, the plurality of positioning columns 121 can also be fixedly arranged in a circumferential array on the storage tray 122.

[0046] Further, the storage assembly 120 further comprises a plurality of buffer rings 123, and each of the plurality of buffer rings 123 is sleeved on a corresponding positioning column 121. In this way, when the bottle mouth of the bottle embryo 20 is inserted into the corresponding positioning column 121, the buffer ring 123 can reduce the collision between the bottle mouth of the bottle embryo 20 and the upper end surface of the storage tray 122, so as to avoid the damage of the bottle mouth of the bottle embryo 20, thereby reducing the loss rate of the bottle embryo 20 during the embryo loading process, and further reducing the cost. The buffer ring 123 can be arranged as a rubber ring, a silica gel ring, a plastic foam ring, etc. according to actual needs. In some other embodiments, a flexible buffer pad can also be directly laid on the upper end surface of the storage tray 122.

[0047] Preferably, the material conveying mechanism 100 further comprises a conveying rack 130, two conveying channels are arranged side by side on the conveying rack 130, the two conveying channels are each provided with a conveying belt 110, and the conveying directions of the two conveying belts 110 are opposite; the conveying channel close to the embryo loading mechanism 200 is provided with a positioning and gripping area corresponding to the embryo loading mechanism 200, and a barrier 132 for limiting the storage assembly 120 in the positioning and gripping area is arranged corresponding to the positioning and gripping area.

[0048] In combination Figure 1As shown, by setting two conveying belts 110 in opposite conveying directions, when the blanking is performed, the conveying belt 110 away from the blanking mechanism 200 is used to place the empty storage assembly 120, so that the operator inserts the bottle blank 20 into the empty storage assembly 120, and prepares for the subsequent blanking mechanism 200 to grab the bottle blank 20; then the storage assembly 120 with the inserted bottle blank 20 is conveyed to the positioning and grabbing area through the conveying belt 110 close to the blanking mechanism 200; and with the aid of the blocking device 132, the storage assembly 120 with the inserted bottle blank 20 is positioned in the positioning and grabbing area, so that the grabbing assembly 230 grabs the bottle blank 20 on the storage assembly 120 to complete the blanking process. The form and installation position of the blocking device 132 are set according to the prior art, which will not be limited here.

[0049] Preferably, at least one lifting and transplanting assembly (not shown in the figure) is arranged on each of the two conveying belts 110, which can lift and transplant the storage assembly 120 from the current conveying belt 110 to the other conveying belt 110. In this way, after the operator inserts the bottle blank 20 into the empty storage assembly 120, the lifting and transplanting assembly corresponding to the conveying belt 110 away from the blanking mechanism 200 lifts and transplants the storage assembly 120 with the inserted bottle blank 20 to the conveying belt 110 close to the blanking mechanism 200, and then with the operation of the conveying belt 110, the storage assembly 120 with the inserted bottle blank 20 is positioned in the positioning and grabbing area to complete the blanking work, while the operator inserts the bottle blank 20 into the empty storage assembly 120 on the conveying belt 110 away from the blanking mechanism 200; when the bottle blank 20 on the storage assembly 120 in the positioning and grabbing area is grabbed, with the operation of the conveying belt 110, the lifting and transplanting assembly corresponding to the conveying belt 110 close to the blanking mechanism 200 lifts and transplants the empty storage assembly 120 to the conveying belt 110 away from the blanking mechanism 200 to prepare for the next insertion of the bottle blank 20. In this way, the blanking is realized in a circular path, which further improves the blanking efficiency. The lifting and transplanting assembly is set according to the prior art, which will not be repeated here.

[0050] Preferably, the blanking device further comprises a first sensor (not shown in the figure) and a second sensor (not shown in the figure) both in communication connection with the blanking mechanism 200, the first sensor is arranged at the entrance of the blanking slide 10 to sense whether there is a bottle blank 20 at the entrance of the blanking slide 10, and the second sensor is arranged at the positioning and grabbing area to sense whether there is a storage assembly 120 in the positioning and grabbing area.

[0051] In the embryo process, after the conveying belt 110 conveys the bottle embryo 20 inserted into the placing assembly 120 to the positioning and grabbing area, the second sensor sends a grabbing signal to the embryo mechanism 200, so that the embryo mechanism 200 can timely and accurately grab the bottle embryo 20; then the embryo mechanism 200 drives the bottle embryo 20 to the entrance of the lower embryo chute 10, and if the first sensor senses that there is no bottle embryo 20 at the entrance of the lower embryo chute 10 at this time, a release signal is sent to the embryo mechanism 200, so that the grabbing assembly 230 puts the grabbed bottle embryo 20 into the entrance of the lower embryo chute 10, avoiding the collision between the current bottle embryo 20 and the original bottle embryo 20 at the entrance of the lower embryo chute 10. In the whole process, through the cooperation of the first sensor, the second sensor and the embryo mechanism 200, the embryo mechanism 200 can timely and accurately grab the bottle embryo 20 placed in the positioning and grabbing area, and put the grabbed bottle embryo 20 into the entrance of the lower embryo chute 10, and can avoid the interference between the current bottle embryo 20 and other bottle embryos 20, so that the automatic embryo is realized while the embryo effect is ensured.

[0052] Further, the positioning and grabbing area is provided with a limiting column which can be lifted and lowered, the placing tray 122 is provided with a limiting hole through which the limiting column passes, and the limiting column is in communication connection with the second sensor. The second sensor can be a weight sensor. In order to further limit the relative position of the placing assembly 120 in the positioning and grabbing area, when the placing assembly 120 with the bottle embryo 20 inserted therein is located in the positioning and grabbing area, the weight sensor senses the increase of the weight and sends a lifting signal to the limiting column, the limiting column is lifted and inserted into the limiting hole to further limit the placing tray 122; after the feeding is completed, the weight of the placing assembly 120 is reduced, and the weight sensor sends a retracting signal to the limiting column, the limiting column is lowered and retracted and separated from the limiting hole, so that the empty placing tray 122 is conveyed out of the positioning and grabbing area, and the next placing assembly 120 with the bottle embryo 20 inserted therein is conveyed into the positioning and grabbing area. The number of the limiting columns can be adaptively set according to actual needs, which can meet the technical effect of further positioning the placing assembly 120 with the bottle embryo 20 inserted therein in the positioning and grabbing area while avoiding interference with multiple limiting columns 121. The number and position of the limiting holes on the placing tray 122 correspond to the limiting columns. The power member for driving the limiting column to lift and lower can be a motor, an air cylinder or the like according to actual needs, which is not limited here.
