[0002] The blow molding machine is mainly a mechanical equipment for blow molding, processing, and production of plastic bottles. When processing plastic bottles, conventional preforms can be untidied on the preform untidier with the help of support rings, and then enter the preform chute of the blow molding machine. When producing large-volume bottles, since large preforms without support rings cannot be untidied by conventional preform untidiers, it is usually necessary to manually take the large preforms out of the frame and then hang them on the preform chute of the blow molding machine; and since the preform chute is usually relatively high, it usually requires at least two people to cooperate with each other, which has high labor costs, high labor intensity, and low preform loading efficiency; and the preform loading method that partially relies on the preform loading robot can save labor costs, but it is impossible to accurately grasp the timing of grabbing and loading the preforms, so the preform loading effect is poor.

Both the first sensor and the second sensor are communicatively connected to the gripping mechanism.

[0009] As a further technical solution, the transmission assembly includes an X transmission member, a Z transmission member and a rotation transmission member, and the sensing assembly also includes a third sensor;

[0010] The X transmission member is arranged on the support frame, the Z transmission member is movably arranged on the X transmission member along the X direction, the rotating transmission member is movably arranged on the Z transmission member along the Z direction, the grabbing assembly is transmission-connected to the rotating transmission member, and the rotating transmission member can drive the grabbing assembly to rotate around the axial direction of the grabbing assembly, and the third sensor is arranged on one side of the placement tray, for sensing the orientation of the bottle mouth of the bottle preform placed on the placement tray, and is communicatively connected with the rotating transmission member.

[0011] As a further technical solution, the support frame is provided with a connecting shaft extending along the Y direction, and the X transmission member is movably connected to the connecting shaft along the Y direction.

[0012] As a further technical solution, the sensing component also includes a visual sensing component, which is arranged corresponding to the placement tray and is communicatively connected to the gripping mechanism, and the visual sensing area of ​​the visual sensing component at least covers the placement tray and the entrance of the lower embryo slide.

[0013] As a further technical solution, the gripping assembly includes a clamping cylinder and two clamping plates, the two clamping plates are both transmission-connected to the clamping cylinder, and are relatively spaced apart along the X direction to form a clamping space, and the end surfaces of the two clamping plates close to each other are both set as clamping curved surfaces.

[0014] As a further technical solution, the grabbing assembly further includes two flexible members, and the two flexible members are arranged on the two clamping curved surfaces in a one-to-one correspondence.

[0015] As a further technical solution, the upper end surface of the placement tray is provided with a first rib and two second ribs, the first rib is arranged opposite to the conveyor belt, and the two second ribs are arranged relatively and spaced apart along the Y direction, the first rib and the two second ribs cooperate with the placement tray to form a accommodating space for accommodating the bottle embryo, and the second sensor is arranged on one of the second ribs.

[0017] As a further technical solution, the loading mechanism further includes a plurality of placement plates, which are evenly spaced on the conveyor belt along the conveying direction of the conveyor belt, and a receiving cavity for receiving the preform is formed between two adjacent placement plates.

[0018] As a further technical solution, the feeding mechanism further includes two baffles, both of which extend along the X direction and are arranged at opposite sides of the conveyor belt in parallel and at intervals along the Y direction.

[0019] Compared with the prior art, the automatic embryo loading device provided by the present invention has the following technical advantages:

[0020] 1. Since the corresponding embryo slide is provided with a loading mechanism and a grabbing mechanism, when loading embryos on the embryo slide, the operator only needs to place the preforms on the conveyor belt, and then the conveyor belt conveys the preforms to the placement tray, and then the grabbing assembly grabs the preforms placed in the placement tray, and then the transmission assembly drives the grabbing assembly to move, so that the grabbing assembly puts the grabbed preforms into the entrance of the embryo slide, and the loading is completed once. During the whole process, only one operator is needed to complete the embryo loading process, and when loading embryos, the operator only needs to place the preforms on the conveyor belt, so that labor can be saved, thereby reducing labor costs and improving embryo loading efficiency.

[0021] 2. Since the first sensor is used to sense whether there is a preform at the entrance of the embryo slide, and the second sensor is used to sense whether there is a preform on the placement tray, the first sensor and the second sensor are both connected to the gripping mechanism. Therefore, during the embryo loading process, after the conveyor belt conveys the preform to the placement tray, the second sensor sends a gripping signal to the gripping mechanism so that the gripping mechanism can grab the preform in a timely and accurate manner; then the gripping mechanism drives the preform to the entrance of the embryo slide. If the first sensor senses that there is no preform at the entrance of the embryo slide at this time, the release signal is transmitted to the gripping mechanism so that the gripping component can put the gripped preform into the entrance of the embryo slide to avoid the current preform colliding with the original preform at the entrance of the embryo slide. In the whole process, the first sensor, the second sensor and the gripping mechanism cooperate with each other, so that the gripping mechanism can grab the preform placed in the placement tray in a timely and accurate manner, and put the gripped preform into the entrance of the embryo slide, and can avoid the current preform from interfering with other preforms. In this way, automatic embryo loading is achieved while ensuring the embryo loading effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Combination Figures 1 to 4As shown, the automatic embryo loading device provided in this embodiment is arranged on one side of the inlet end of the lower embryo chute 10 in the bottle blowing machine, and is used to realize automatic embryo loading on the lower embryo chute 10, and ensure the embryo loading effect and efficiency, and reduce labor intensity and labor costs. Specifically, the automatic embryo loading device includes a loading mechanism 100, a gripping mechanism 200 and a sensing component: the loading mechanism 100 includes a conveyor belt 110 and a placement tray 120. Along the conveying direction of the conveyor belt 110, the placement tray 120 is arranged at one end of the conveyor belt 110 and is arranged corresponding to the inlet end of the lower embryo chute 10. The conveyor belt 110 can transport the bottle preforms 20 placed on the conveyor belt 110 to the placement tray 120; the gripping mechanism 200 includes a support frame 210, a transmission component 220 and a gripping component 230. The support frame 210 is arranged on one side of the inlet end of the lower embryo chute 10. The transmission assembly 220 is movably arranged on the support frame 210 and is located above the placement tray 120. The grabbing assembly 230 is transmission-connected to the transmission assembly 220 and is used to grab the bottle embryo 20 placed in the placement tray 120. The transmission assembly 220 can drive the grabbing assembly 230 to place the grabbed bottle embryo 20 into the entrance of the lower embryo slide 10; the sensing assembly includes a first sensor for sensing whether there is a bottle embryo 20 at the entrance of the lower embryo slide 10 and a second sensor 310 for sensing whether there is a bottle embryo 20 on the placement tray 120. The first sensor and the second sensor 310 are both communicatively connected to the grabbing mechanism 200.

[0040] In this embodiment, the preform chute 10 extends along the Y direction, and the conveyor belt 110 conveys the preforms 20 along the X direction. In other embodiments, the extension direction of the preform chute 10 and the conveying direction of the conveyor belt 110 can be set according to actual needs, and are not limited thereto.

[0041] Since the corresponding embryo slide 10 is provided with a loading mechanism 100 and a grabbing mechanism 200, when loading the embryos on the embryo slide 10, the operator only needs to place the bottle preforms 20 on the conveyor belt 110, and then the conveyor belt 110 conveys the bottle preforms 20 to the placement tray 120, and then the grabbing assembly 230 grabs the bottle preforms 20 placed in the placement tray 120, and then the transmission assembly 220 drives the grabbing assembly 230 to move, so that the grabbing assembly 230 puts the grabbed bottle preforms 20 into the entrance of the embryo slide 10, and one loading is completed. In the whole process, only one operator is needed to complete the embryo loading process, and when loading the embryos, the operator only needs to place the bottle preforms 20 on the conveyor belt 110, so that labor can be saved, thereby reducing labor costs and improving embryo loading efficiency.

[0042] Since the first sensor is used to sense whether there is a preform 20 at the entrance of the embryo chute 10, and the second sensor 310 is used to sense whether there is a preform 20 on the placement tray 120, the first sensor and the second sensor 310 are both connected to the gripping mechanism 200. Therefore, during the embryo loading process, after the conveyor belt 110 conveys the preform 20 to the placement tray 120, the second sensor 310 sends a gripping signal to the gripping mechanism 200, so that the gripping mechanism 200 can grasp the preform 20 in a timely and accurate manner; then the gripping mechanism 200 drives the preform 20 to the entrance of the embryo chute 10, and if the first sensor senses that there is no preform 20 at the entrance of the embryo chute 10, a release signal is transmitted to the gripping mechanism 200, so that the gripping component 230 puts the gripped preform 20 into the entrance of the embryo chute 10, so as to avoid the current preform 20 from colliding with the original preform 20 at the entrance of the embryo chute 10. During the whole process, the first sensor and the second sensor 310 cooperate with the grasping mechanism 200, so that the grasping mechanism 200 can grasp the preforms 20 placed in the placing tray 120 in a timely and accurate manner, and put the grasped preforms 20 into the entrance of the preform lowering slide 10, and can avoid the interference between the current preforms 20 and other preforms 20, so that automatic preform loading is achieved while ensuring the preform loading effect.

[0043] Preferably, the transmission assembly 220 includes an X transmission member 221, a Z transmission member 222 and a rotating transmission member 223, and the sensing assembly further includes 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 rotating transmission member 223 is movably arranged on the Z transmission member 222 along the Z direction, the grabbing assembly 230 is transmission-connected to the rotating transmission member 223, and the rotating transmission member 223 can drive the grabbing assembly 230 to rotate around the axial direction of the grabbing assembly 230, and the third sensor is arranged on one side of the placement tray 120, for sensing the orientation of the bottle mouth of the bottle preform 20 placed in the placement tray 120, and is communicatively connected with the rotating transmission member 223.

[0044] Combination Figure 4 As described above, the X transmission member 221 is provided with an X slide rail extending in the X direction, and the Z transmission member 222 is slidably connected to the X slide rail to drive the grabbing assembly 230 to move in the X direction; the Z transmission member 222 is provided with a Z slide rail extending in the Z direction, and the rotating transmission member 223 is slidably connected to the Z slide rail to drive the grabbing assembly 230 to move in the Z direction. Thus, the preform 20 grabbed by the grabbing assembly 230 is placed into the entrance of the lower preform slide 10.

[0045] Furthermore, in order to facilitate the preform 20 to slide along the embryo slide 10, when the preform 20 is placed in the embryo slide 10, the mouth of the preform 20 needs to be slidably matched with the embryo slide 10; therefore, in this embodiment, a second sensor 310 is provided on one side of the placement tray 120. Before the grabbing assembly 230 grabs the preform 20, if the second sensor 310 senses that the mouth of the current preform 20 is facing the entrance of the embryo slide 10 after being grabbed, the rotating transmission member 223 does not move, and directly drives the grabbing assembly 230 to put the preform 20 into the embryo slide 10; if the second sensor 310 senses that the bottom of the current preform 20 is facing the entrance of the embryo slide 10 after being grabbed, the rotating transmission member 223 drives the grabbing assembly 230 to rotate 180° until the mouth of the current preform 20 is facing the entrance of the embryo slide 10. In this way, the efficiency of embryo loading is further improved and the embryo loading effect is guaranteed.

[0046] Preferably, the support frame 210 is provided with a connecting shaft 211 extending in the Y direction, and the X transmission member 221 is movably connected to the connecting shaft 211 in the Y direction. In the process of the preform 20 being conveyed from the conveyor belt 110 to the storage tray 120, the preform 20 may be displaced in the Y direction, so that when the grabbing assembly 230 grabs the preform 20, it does not clamp the middle part of the preform 20, resulting in the preform 20 being dropped from the grabbing assembly 230 after being grabbed. In order to avoid the above situation and further improve the grabbing accuracy and grabbing stability of the preform 20, in this embodiment, a Y slide extending in the Y direction is provided on the connecting shaft 211, and the X transmission member 221 is slidably connected to the Y slide. The position adjustment of the grabbing assembly 230 in the Y direction is achieved by the cooperation between the connecting shaft 211 and the X transmission member 221.

[0047] Furthermore, the sensing component further includes a visual sensing component, which is arranged corresponding to the placement tray 120 and is in communication connection with the gripping mechanism 200, and the visual sensing area of ​​the visual sensing component at least covers the placement tray 120 and the entrance of the embryo loading chute 10. The visual sensing component directly obtains the existence status and position of the bottle preform 20 in the placement tray 120, and obtains whether there is a bottle preform 20 at the entrance of the embryo loading chute 10, and transmits the visual signal to the gripping mechanism 200, and cooperates with the first sensor and the second sensor 310 to further improve the accuracy and stability of the gripping mechanism 200 when gripping the bottle preform 20, and ensure the efficiency of embryo loading. In other embodiments, according to actual needs, only the first sensor and the second sensor 310 can be set; or only the visual sensing component can be set.

[0048] Preferably, the gripping assembly 230 includes a clamping cylinder 231 and two clamping plates 232. The two clamping plates 232 are both connected to the clamping cylinder 231 and are arranged at a relative interval along the X direction to form a clamping space, and the end surfaces of the two clamping plates 232 close to each other are both set as clamping curved surfaces. The clamping cylinder 231 drives the two clamping plates 232 to move closer to or away from each other to achieve gripping of the preform 20; by setting the end surfaces of the two clamping plates 232 close to each other as clamping curved surfaces, the probability of causing gripping damage to the clamped preform 20 during the gripping process of the preform 20 is reduced.

[0049] When the grabbing assembly 230 grabs the preform 20, in order to prevent the clamping plate 232 from clamping the preform 20 and further improve the preform loading effect, in this embodiment, the grabbing assembly 230 also includes two flexible parts, which are arranged on the two clamping curved surfaces in a one-to-one correspondence. The flexible parts can be set as rubber parts, silicone parts or plastic parts according to actual needs, and are not specifically limited here.

[0050] Preferably, the upper end surface of the placing tray 120 is provided with a first rib 121 and two second ribs 122, the first rib 121 is arranged opposite to the conveyor belt 110, and the two second ribs 122 are arranged relatively and spaced along the Y direction, and the first rib 121 and the two second ribs 122 cooperate with the placing tray 120 to form a receiving space for receiving the bottle preform 20, so as to prevent the bottle preform 20 from falling from the placing tray 120 after being conveyed from the conveyor belt 110 to the placing tray 120, so as to improve the effect and safety of placing the preform. The second sensor 310 is arranged on one of the second ribs 122 to improve the accuracy of the second sensor 310 in sensing the orientation of the bottle mouth of the bottle preform 20.

[0051] When the grabbing assembly 230 grabs the preform 20 in the placing tray 120 , in order to avoid interference between the grabbing assembly 230 and the first rib 121 and thus affecting the grabbing effect, in this embodiment, a grabbing avoidance groove 1211 is provided in the middle of the first rib 121 .

[0052] Preferably, the loading mechanism 100 further includes a plurality of placement plates 130 , which are evenly spaced on the conveyor belt 110 along the conveying direction of the conveyor belt 110 , and a receiving cavity for receiving the preform 20 is formed between two adjacent placement plates 130 .

[0053] Specific combination Figure 1 and Figure 3As shown, with such arrangement, when the preforms 20 are conveyed to the placing tray 120 by the conveyor belt 110, the preforms 20 are placed in the corresponding accommodating cavities. On the one hand, the relative positions of two adjacent preforms 20 are limited along the conveying direction of the conveyor belt 110 to avoid collision, friction, etc.; on the other hand, the size of the accommodating cavity is adjusted by adjusting the distance between two adjacent baffles 140, so that the conveying rhythm of the preforms 20 can be adjusted. At the same time, it is suitable for conveying preforms 20 of different volumes, thereby improving its applicability.

[0054] Preferably, the loading mechanism 100 further includes two baffles 140, both of which extend in the X direction and are arranged at intervals and in parallel on both sides of the conveyor belt 110 in the Y direction. In this arrangement, the two baffles 140 cooperate with the conveyor belt 110 to prevent the preforms 20 from falling off the conveyor belt 110 in the X direction during the conveyor belt 110 conveying the preforms 20, thereby further improving the loading effect.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
