Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of embryo feeding on bottle blowing machine, and particularly to an automatic embryo feeding device. BACKGROUND

[0002] The bottle blowing machine is mainly a mechanical equipment for blowing, processing and producing plastic bottles. When processing plastic bottles, the conventional bottle embryo can be completed by the embryo sorting machine with the help of a supporting ring, and then enters the embryo feeding slide of the bottle blowing machine. However, when producing large-volume bottles, the large bottle embryo without a supporting ring cannot be sorted by a conventional embryo sorting machine, and usually needs to be manually taken out of the frame and hung on the embryo feeding slide of the bottle blowing machine. Since the embryo feeding slide is usually high, at least two workers are usually needed to complete the task, which is high in labor cost and labor intensity, and low in embryo feeding efficiency. Although the embryo feeding mode with the help of the embryo feeding manipulator can save labor cost, it cannot accurately grasp the timing of grabbing and embryo feeding, and thus the embryo feeding effect is poor.

[0015] As a further technical scheme, the upper end face of the placing disc is provided with a first stop edge and two second stop edges, the first stop edge is oppositely arranged to the conveying belt, both of the second stop edges are oppositely and spaced apart along the Y direction, the first stop edge and both of the second stop edges cooperate with the placing disc to form a containing space for containing the bottle embryo, and the second sensor is arranged on one of the second stop edges.

[0016] As a further technical scheme, the middle part of the first stop edge is provided with a grabbing avoiding groove.

Since the first sensor is used to sense whether there is a bottle embryo at the entrance of the embryo feeding chute, the second sensor is used to sense whether there is a bottle embryo in the placing tray, and the first sensor and the second sensor are in communication connection with the grabbing mechanism. Therefore, during the embryo feeding process, after the conveying belt feeds the bottle embryo into the placing tray, the second sensor sends a grabbing signal to the grabbing mechanism, so that the grabbing mechanism can timely and accurately grab the bottle embryo; then the grabbing mechanism drives the bottle embryo to the entrance of the embryo feeding chute, and if the first sensor senses that there is no bottle embryo at the entrance of the embryo feeding chute at this time, a release signal is transmitted to the grabbing mechanism, so that the grabbing assembly puts the grabbed bottle embryo into the entrance of the embryo feeding chute, avoiding the collision between the current bottle embryo and the original bottle embryo at the entrance of the embryo feeding chute. In the whole process, through the cooperation of the first sensor, the second sensor and the grabbing mechanism, the grabbing mechanism can timely and accurately grab the bottle embryo placed in the placing tray and put the grabbed bottle embryo into the entrance of the embryo feeding chute, and the interference between the current bottle embryo and other bottle embryos can be avoided, so that the automatic embryo feeding is realized while the embryo feeding effect is guaranteed.

[0039] In combination Figures 1 to 4As shown, the automatic embryo feeding device provided by the embodiment is arranged at one side of the inlet end of the embryo slide 10 of the bottle blowing machine, and is used to realize automatic embryo feeding to the embryo slide 10, ensure embryo feeding effect and embryo feeding efficiency, and reduce labor intensity and labor cost. Specifically, the automatic embryo feeding device comprises a feeding mechanism 100, a grabbing mechanism 200 and a sensing assembly: the feeding mechanism 100 comprises a conveying belt 110 and a placing disc 120, along the conveying direction of the conveying belt 110, the placing disc 120 is arranged at one end of the conveying belt 110 and is arranged correspondingly with the inlet end of the embryo slide 10, and the conveying belt 110 can convey the bottle embryo 20 placed on the conveying belt 110 into the placing disc 120; the grabbing mechanism 200 comprises a support frame 210, a transmission assembly 220 and a grabbing assembly 230, the support frame 210 is arranged at one side of the inlet end of the embryo slide 10, the transmission assembly 220 is movably arranged on the support frame 210 and located above the placing disc 120, and the grabbing assembly 230 is transmissionally connected to the transmission assembly 220 and is used to grab the bottle embryo 20 placed in the placing disc 120, and the transmission assembly 220 can drive the grabbing assembly 230 to place the grabbed bottle embryo 20 into the inlet of the embryo slide 10; the sensing assembly comprises a first sensor for sensing whether there is a bottle embryo 20 at the inlet of the embryo slide 10 and a second sensor 310 for sensing whether there is a bottle embryo 20 in the placing disc 120, and the first sensor and the second sensor 310 are both communicatively connected with the grabbing mechanism 200.

[0040] In the embodiment, the embryo slide 10 extends along the Y direction, and the conveying belt 110 conveys the bottle embryo 20 along the X direction, which is taken as an example for description. In some other embodiments, the extension direction of the embryo slide 10 and the conveying direction of the conveying belt 110 can be set according to actual needs, which is not limited thereto.

[0041] Since the feeding mechanism 100 and the grabbing mechanism 200 are arranged correspondingly with the embryo slide 10, when feeding the embryo to the embryo slide 10, the operator only needs to place the bottle embryo 20 on the conveying belt 110, and then the conveying belt 110 conveys the bottle embryo 20 into the placing disc 120, and then the grabbing assembly 230 grabs the bottle embryo 20 placed in the placing disc 120, and then the transmission assembly 220 drives the grabbing assembly 230 to move, so that the grabbing assembly 230 places the grabbed bottle embryo 20 into the inlet of the embryo slide 10, thereby completing one feeding. In the whole process, only one operator is needed to complete the embryo feeding process, and when feeding the embryo, the operator only needs to place the bottle embryo 20 on the conveying belt 110, so that the labor can be saved, thereby reducing the labor cost and improving the embryo feeding efficiency.

[0042] The first sensor is used to sense whether there is a bottle embryo 20 at the entrance of the lower embryo slide 10, and the second sensor 310 is used to sense whether there is a bottle embryo 20 in the placing disc 120. The first sensor and the second sensor 310 are both in communication connection with the grabbing mechanism 200. Therefore, during the embryo loading process, after the conveying belt 110 conveys the bottle embryo 20 into the placing disc 120, the second sensor 310 sends a grabbing signal to the grabbing mechanism 200, so that the grabbing mechanism 200 can timely and accurately grab the bottle embryo 20. Then the grabbing mechanism 200 drives the bottle embryo 20 to the entrance of the lower embryo slide 10. If the first sensor senses that there is no bottle embryo 20 at the entrance of the lower embryo slide 10 at this time, a release signal will be transmitted to the grabbing mechanism 200, so that the grabbing assembly 230 can put the grabbed bottle embryo 20 into the entrance of the lower embryo slide 10, avoiding the collision between the current bottle embryo 20 and the original bottle embryo 20 at the entrance of the lower embryo slide 10. In the whole process, through the cooperation of the first sensor and the second sensor 310 with the grabbing mechanism 200, the grabbing mechanism 200 can timely and accurately grab the bottle embryo 20 placed in the placing disc 120, and put the grabbed bottle embryo 20 into the entrance of the lower embryo slide 10, and can avoid the interference between the current bottle embryo 20 and other bottle embryos 20. In this way, the automatic embryo loading is realized, and the embryo loading effect is guaranteed.

[0043] Preferably, the transmission assembly 220 comprises an X transmission member 221, a Z transmission member 222 and a rotary transmission member 223, and the sensing assembly further comprises a third sensor. The X transmission member 221 is arranged on the support frame 210, the Z transmission member 222 is movably arranged on the X transmission member 221 along the X direction, the rotary transmission member 223 is movably arranged on the Z transmission member 222 along the Z direction, the grabbing assembly 230 is in transmission connection with the rotary transmission member 223, and the rotary transmission member 223 can drive the grabbing assembly 230 to rotate around the axial direction of the grabbing assembly 230. The third sensor is arranged on one side of the placing disc 120 and is used to sense the orientation of the bottle mouth of the bottle embryo 20 placed in the placing disc 120. The third sensor is in communication connection with the rotary transmission member 223.

[0044] In combination Figure 4 As described above, the X transmission member 221 is provided with an X sliding rail extending along the X direction, and the Z transmission member 222 is in sliding connection with the X sliding rail, so as to drive the grabbing assembly 230 to move in the X direction. The Z transmission member 222 is provided with a Z sliding rail extending along the Z direction, and the rotary transmission member 223 is in sliding connection with the Z sliding rail, so as to drive the grabbing assembly 230 to move in the Z direction. In this way, the grabbed bottle embryo 20 can be put into the entrance of the lower embryo slide 10.

[0045] Further, in order to facilitate the bottle embryo 20 to slide along the lower embryo slide 10, the bottle mouth of the bottle embryo 20 needs to be matched with the lower embryo slide 10 when the bottle embryo 20 is placed into the lower embryo slide 10. Therefore, in the embodiment, the second sensor 310 is arranged on one side of the placing disc 120. Before the bottle embryo 20 is grabbed by the grabbing assembly 230, if the second sensor 310 senses that the bottle mouth of the current bottle embryo 20 is directed to the entrance of the lower embryo slide 10 after the bottle embryo 20 is grabbed, the rotating transmission member 223 does not move, and directly drives the grabbing assembly 230 to place the bottle embryo 20 into the lower embryo slide 10. If the second sensor 310 senses that the bottle bottom of the current bottle embryo 20 is directed to the entrance of the lower embryo slide 10 after the bottle embryo 20 is grabbed, the rotating transmission member 223 drives the grabbing assembly 230 to rotate by 180° until the bottle mouth of the current bottle embryo 20 is directed to the entrance of the lower embryo slide 10. In this way, the embryo loading efficiency is further improved, and the embryo loading effect is ensured.

[0046] Preferably, the support frame 210 is provided with a connecting shaft 211 extending along the Y direction, and the X transmission member 221 is movably connected to the connecting shaft 211 along the Y direction. During the process that the bottle embryo 20 is conveyed from the conveying belt 110 to the placing disc 120, the bottle embryo 20 may be displaced in the Y direction, so that the grabbing assembly 230 clamps the middle part of the bottle embryo 20 when grabbing the bottle embryo 20, which may cause the bottle embryo 20 to fall from the grabbing assembly 230 after being grabbed. In order to avoid the above situation and further improve the grabbing precision and stability of the bottle embryo 20, the connecting shaft 211 is provided with a Y sliding groove extending along the Y direction, and the X transmission member 221 is slidably connected to the Y sliding groove. The position adjustment of the grabbing assembly 230 in the Y direction is realized through the cooperation of the connecting shaft 211 and the X transmission member 221.

[0047] Further, the sensing assembly further comprises a visual sensing member, which is arranged corresponding to the placing disc 120 and is in communication connection with the grabbing mechanism 200, and the visual sensing area of the visual sensing member covers at least the placing disc 120 and the entrance of the lower embryo slide 10. The visual sensing member directly obtains the existence state and position of the bottle embryo 20 in the placing disc 120, and obtains whether there is a bottle embryo 20 at the entrance of the lower embryo slide 10, and transmits the visual signal to the grabbing mechanism 200, which cooperates with the first sensor and the second sensor 310 to further improve the precision and stability of the grabbing mechanism 200 when grabbing the bottle embryo 20, and ensure the embryo loading efficiency. In some other embodiments, according to actual needs, only the first sensor and the second sensor 310 can be arranged; or only the visual sensing member can be arranged.

[0048] Preferably, the grabbing assembly 230 comprises a clamping cylinder 231 and two clamping plates 232, both of which are drivingly connected to the clamping cylinder 231 and oppositely spaced apart along the X direction to form a clamping space, and the end faces of both of the clamping plates 232 that are close to each other are provided with clamping curved surfaces. The clamping cylinder 231 drives the two clamping plates 232 to move close to or away from each other to achieve grabbing of the bottle blank 20; and the end faces of both of the clamping plates 232 that are close to each other are provided with clamping curved surfaces to reduce the probability of causing damage to the bottle blank 20 during grabbing.

[0049] When the grabbing assembly 230 grabs the bottle blank 20, in order to avoid the clamping plate 232 from damaging the bottle blank 20 and further improve the blank loading effect, in the embodiment, the grabbing assembly 230 further comprises two flexible members, which are correspondingly arranged on the two clamping curved surfaces. The flexible member can be made of rubber, silicone or plastic according to actual needs, which is not limited here.

[0050] Preferably, the upper end face of the placing disc 120 is provided with a first retaining edge 121 and two second retaining edges 122, the first retaining edge 121 is arranged opposite to the conveying belt 110, and the two second retaining edges 122 are oppositely spaced apart along the Y direction. The first retaining edge 121 and the two second retaining edges 122 cooperate with the placing disc 120 to form a containing space for containing the bottle blank 20, so as to avoid the bottle blank 20 from falling off the placing disc 120 after being conveyed from the conveying belt 110 to the placing disc 120, thereby improving the blank loading effect and safety. The second sensor 310 is arranged on one of the second retaining edges 122 to improve the accuracy of the second sensor 310 in sensing the orientation of the bottle mouth of the bottle blank 20.

[0051] When the grabbing assembly 230 grabs the bottle blank 20 in the placing disc 120, in order to avoid the grabbing assembly 230 from interfering with the first retaining edge 121 and affecting the grabbing effect, in the embodiment, the middle part of the first retaining edge 121 is provided with a grabbing avoiding groove 1211.

[0052] Preferably, the feeding mechanism 100 further comprises a plurality of placing plates 130, which are uniformly and spaced apart along the conveying direction of the conveying belt 110 and arranged on the conveying belt 110, and a containing cavity for containing the bottle blank 20 is formed between adjacent two placing plates 130.

[0053] Specifically combined Figure 1 and Figure 3As shown, in this way, when the bottle embryo 20 is conveyed to the placing disc 120 through the conveying belt 110, the bottle embryo 20 is placed in the corresponding accommodation cavity, on the one hand, the relative positions of two adjacent bottle embryos 20 are limited along the conveying direction of the conveying belt 110, so that the collision and friction and the like are avoided; on the other hand, by adjusting the distance between two adjacent baffles 140, the size of the accommodation cavity is adjusted, so that the adjustment of the conveying rhythm of the bottle embryo 20 can be realized, and meanwhile, the baffles 140 are suitable for conveying bottle embryos 20 with different volumes, and the applicability is improved.

[0054] Preferably, the feeding mechanism 100 further comprises two baffles 140, both of which extend along the X direction and are arranged on both sides of the conveying belt 110 in parallel along the Y direction. In this way, by the cooperation of the two baffles 140 and the conveying belt 110, the situation that the bottle embryo 20 falls off from the conveying belt 110 in the X direction is avoided during the conveying of the bottle embryo 20 by the conveying belt 110, so that the feeding effect is further improved.

[0055] Obviously, the above embodiments of the present application are only examples for clarity, and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
