[0002] The alternating variable pitch bottle transport mechanism is a variable pitch conversion mechanism that transports blow-molded bottles from the bottle blowing machine to the filling machine during the bottle production process. Currently, the bottle blowing machine connected to the filling mechanism on the market is generally connected by an air delivery channel, which consists of a 30-50 meter long air delivery pipeline, and there are two air delivery tracks in the pipeline. The bottle is provided with an annular groove structure, and the bottle is erected between the two air delivery tracks through the annular groove. There are multiple fans fixed on it to blow air, and the fan guides the bottle to be transported forward on the air delivery track to realize the process of transporting the bottle to the filling machine.

[0003] However, when the fan guides the air to blow and the bottles are transported to the filling machine, they are easily exposed to dust and bacteria in the air, which reduces the hygiene level of the bottled water! The air delivery pipeline is about 30 meters long, which not only takes up space, but also reduces the reliability of the online production due to the long air delivery track, and cannot meet the high-speed and stable production requirements of bottled water. Utility Model Content

[0008] The lateral movement power mechanism is used to be fixed on the main frame, and the output end of the lateral movement power mechanism is connected to the multi-guide groove cam barrel, one end of the spring clamp mechanism is located in the variable pitch guide groove, and its clamping port is set outward, and the lateral movement power mechanism drives the multi-guide groove cam barrel to move laterally on the driving cam shaft, and the rotating bearing in the multi-guide groove cam barrel is restricted by the spiral groove and follows the rotation, and the variable pitch guide groove drives the spring clamp mechanism to move and change the pitch as the multi-guide groove cam barrel rotates.

Since the spacing between adjacent variable pitch guide grooves changes evenly along the spiral direction of the variable pitch guide groove, the pitch change of the spring clamp mechanism is also even. Therefore, the utility model realizes the functions of lateral movement and pitch adjustment at the same time through the lateral movement force mechanism, which not only reduces the occupied space, but also can meet the needs of high-speed, stable and continuous production of bottled water.

[0044] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0045] Embodiment 1

[0046] Please refer to Figures 1 to 8 , an alternating variable pitch bottle transport mechanism, comprising a fixed frame 1, a lateral force mechanism 2, a multi-guide slot variable pitch mechanism 3 and a plurality of spring clamp mechanisms 4. Among them, the multi-guide slot variable pitch mechanism 3 and the plurality of spring clamp mechanisms 4 have only one set, namely Figure 1 and Figure 2 As shown, Figures 3 to 8 The extra group among the two groups of multi-guide groove variable pitch mechanisms 3 and multiple spring clamp mechanisms 4 is only for demonstrating the mechanical matching relationship under different states, and does not indicate that an alternating variable pitch bottle transport mechanism of this embodiment has two groups of multi-guide groove variable pitch mechanisms 3 and multiple spring clamp mechanisms 4 at the same time.

[0047] Reference Figure 5 It can be seen that the multi-guide groove variable pitch mechanism 3 includes a driving cam shaft 31 fixed on the fixed frame 1 and a multi-guide groove cam barrel 32 sleeved on the driving cam shaft 31, the surface of the driving cam shaft 31 is provided with a spiral groove, and the multi-guide groove cam barrel 32 is provided with a rotating bearing 321, and the rotating bearing 321 is located in the spiral groove. The surface of the multi-guide groove variable pitch mechanism 3 is provided with a plurality of spiral variable pitch guide grooves 322, and the spacing between adjacent variable pitch guide grooves 322 changes uniformly along the spiral direction of the variable pitch guide grooves 322. Therefore, the pitch change of the spring clamp mechanism 4 is also uniform. Among them, the transverse movement power mechanism 2 is used to be fixed on the main frame, the output end of the transverse movement power mechanism 2 is connected to the multi-guide groove cam barrel 32, one end of the spring clamp mechanism 4 is located in the variable pitch guide groove 322, and its clamping mouth is set outward, the transverse movement power mechanism 2 drives the multi-guide groove cam barrel 32 to move laterally on the driving cam shaft 31, and the rotating bearing 321 in the multi-guide groove cam barrel 32 is restricted by the spiral groove and follows the rotation, and the variable pitch guide groove 322 drives the spring clamp mechanism 4 to move and change the pitch as the multi-guide groove cam barrel 32 rotates.

[0048] Specific reference Figure 1 and Figure 2It can be seen that the clamp group composed of multiple spring clamp mechanisms 4 is in a closed state at the initial position. At this time, the multiple spring clamp mechanisms 4 are closely arranged, and the spacing between adjacent ones is small. At the end position, the clamp group is in an open state. At this time, the multiple spring clamp mechanisms 4 are dispersedly arranged, and the spacing between adjacent ones is large. Therefore, during the lateral movement of the multi-guide groove variable pitch mechanism 3, the pitch of the multiple spring clamp mechanisms 4 is adjusted at the same time.

[0049] Among them, the length of the driving cam shaft 31 is greater than the length of the multiple spring clamp mechanisms 4 in the open state plus the length of the multiple spring clamp mechanisms 4 in the closed state. In this way, when the multiple spring clamp mechanisms 4 are in the initial position and the end position, they will not interfere with each other due to the mechanical devices corresponding to these two positions. For example, in this embodiment, the initial position is to be connected to the bottle blowing machine directly in front, and the end position is to be connected to a clamping mechanism to transition to the next stage.

[0050] Reference Figures 3 to 5 It can be seen that the present embodiment further includes an alternating telescopic power mechanism 5 and a sliding device, the sliding device includes a fixed part and a sliding part, the fixed part is fixed on the fixed frame 1, the sliding part is used to be fixed on the main frame and slide forward and backward along the fixed part, and the output end of the alternating telescopic power mechanism 5 can be connected with the fixed frame 1 in a manner that it can abut against each other, so as to drive the fixed frame 1, the multi-guide groove variable pitch mechanism 3 and the multiple spring clamp mechanisms 4 to move forward and backward. Thus, the sliding part plays the role of guiding and suspending the alternating telescopic action of the overall alternating variable pitch bottle transport mechanism. In the present embodiment, the fixed part is the first linear rail 11, the sliding part is the first slider 12, the fixed part and the sliding part are provided with four sets, and the fixed parts are evenly distributed along the length direction of the fixed frame 1. In other embodiments, the fixed part and the sliding part can be provided with five sets, six sets, and so on.

[0051] like Figure 5 It can be seen that the alternating telescopic power mechanism 5 includes an alternating telescopic motor 51, a coupling 52, a bearing seat 53, a screw 54, a nut 55 and a connecting seat 56. The alternating telescopic motor 51 is connected to one end of the screw 54 through the coupling 52. The screw 54 is located in the bearing seat 53, and the other end is threadedly connected to the nut 55. The nut 55 is located in the connecting seat 56. The connecting seat 56 is fixedly connected to the fixed frame 1. The alternating telescopic motor 51 drives the fixed frame 1 to move forward and backward through the screw 54, the nut 55 and the connecting seat 56 in sequence. Among them, the cooperation of the screw 54 and the nut 55 converts the rotational motion of the alternating telescopic motor 51 into the forward and backward linear motion of the fixed frame 1.

[0052] Reference Figure 7 and Figure 8It can be seen that the lateral force mechanism 2 includes a second linear rail 21 and a second slider 22, the second linear rail 21 is connected to the multi-guide groove cam barrel 32, the output end of the lateral force mechanism 2 is connected to the second slider 22, and the sliding direction of the second slider 22 on the second linear rail 21 is the same as the sliding direction of the sliding part on the fixed part. In this way, when the entire multi-guide groove variable pitch mechanism 3 moves forward and backward, the lateral force mechanism 2 does not slide, but the second slider 22 slides. At this time, through the cooperation of the second slider 22 and the second linear rail 21, the lateral force mechanism 2 and the multi-guide groove variable pitch mechanism 3 are still in a connection relationship, so it does not affect the lateral force mechanism 2 driving the multi-guide groove variable pitch mechanism 3 to move horizontally.

[0053] Reference Figure 5 and Figure 8 It can be seen that the lateral movement power mechanism 2 includes a lateral movement servo motor 23, a speed reducer 24, a power synchronous wheel 25, a power seat 26, a driven synchronous wheel 27, a secondary shaft 28, a driven seat 29, a belt 210, a pressure block 211 and a lateral movement connecting block 212. The lateral movement servo motor 23 is connected to the power synchronous wheel 25 through the speed reducer 24, the power synchronous wheel 25 is fixed on the power seat 26 through a rotating shaft, and the driven synchronous wheel 27 is fixed on the driven seat 29 through the secondary shaft 28. The power seat 26 and the driven seat 29 are arranged laterally and spaced apart on the side of the fixed frame 1 away from the spring clamp mechanism 4 and are both used to be fixed on the main frame. The belt 210 is sleeved on the power synchronous wheel 25 and the driven synchronous wheel 27 to form a belt 210 transmission structure. The pressure block 211 is fixed on the belt 210 and is connected to the second slider 22 as the output end of the lateral movement power mechanism 2. The second linear rail 21 and the multi-guide groove cam cylinder 32 are connected through the lateral movement connecting block 212. Thus, the transverse movement servo motor 23, the reducer 24, the power synchronous wheel 25, the power seat 26, the driven synchronous wheel 27, the secondary shaft 28, the driven seat 29, and the belt 210 form a belt transmission mechanism, and the pressure block 211 moves laterally following the belt 210, and drives the multi-guide groove cam cylinder 32 to move laterally through the transverse movement connecting block 212.

[0054] Reference Figure 3 and Figure 4It can be seen that the multi-guide groove variable pitch mechanism 3 also includes an alternating variable pitch seat 33, a fixed block 34, a third slider 35, a roller seat 36 and a multi-guide groove cam seat 37. Among them, one roller seat 36 is fixedly arranged on both sides of the fixed frame 1, the driving cam shaft 31 fixed frame 1 is arranged between the two roller seats 36, the multi-guide groove cam seat 37 is fixed on both sides of the alternating variable pitch seat 33, the multi-guide groove cam barrel 32 fixed frame 1 is arranged between the two multi-guide groove cam seats 37, and the output end of the lateral movement force mechanism 2 is connected to the alternating variable pitch seat 33; the fixed block 34 is arranged above the alternating variable pitch seat 33, the third slider 35 is arranged above the fixed block 34, and is slidably connected with the third linear rail 13 arranged on the fixed frame 1, the sliding direction of the third slider 35 and the third linear rail 13 is consistent with the lateral movement direction of the multi-guide groove cam barrel 32, and the fixed block 34 and the third slider 35 are evenly distributed in multiple groups along the alternating variable pitch seat 33. That is, the driving cam shaft 31 serves as a fixed shaft, the multi-guide groove cam barrel 32 is a sliding part, and the third slider 35 and the third linear rail 13 serve to guide the lateral sliding. During the lateral sliding of the multi-guide groove cam barrel 32, its rotating bearing 321 is guided by the spiral groove on the driving cam shaft 31 and rotates itself. In this way, the variable pitch guide groove 322 drives the spring clamp mechanism 4 to move and change the pitch as the multi-guide groove cam barrel 32 rotates.

[0055] Reference Figures 3 to 6 It can be seen that a fourth slider 41 is provided on the spring clamp mechanism 4 , a fourth linear rail 38 is provided below the alternating pitch seat 33 , the fourth slider 41 is slidably connected to the fourth linear rail 38 , and the sliding direction is consistent with the lateral movement direction of the multi-guide groove cam cylinder 32 .

[0056] Reference Figure 6 It can be seen that the spring clamp mechanism 4 includes a clamp fixing seat 42 and two left and right clamping jaws 43, a spring 44, a guard plate 45, a fixing pin 46 and a pitch-changing bearing 47 arranged on the clamp fixing seat 42. Among them, the clamp fixing seat 42 is fixedly connected to the fourth slider 41, the front ends of the left and right clamping jaws 43 form a clamping opening, and the rear ends are sleeved on a connecting rod, the spring 44 is sleeved on the connecting rod and clamped in the middle by the rear ends of the left and right clamping jaws 43, the guard plate 45 is arranged on the bottom surface of the clamp fixing seat 42, two fixing pins 46 are arranged, and they pass through the middle area of ​​the left and right clamping jaws 43 and are fixedly connected to the guard plate 45, and the pitch-changing bearing 47 is fixed on one end of the clamp fixing seat 42 close to the multi-guide groove cam cylinder 32, and the pitch-changing bearing 47 is located in the pitch-changing guide groove 322. Among them, the pitch-changing bearing 47 is located in the pitch-changing guide groove 322, so the pitch-changing bearing 47 drives the entire spring clamp mechanism 4 to slide along the fourth linear rail 38.

[0057] At this time, there is a fixed pin 46 in the middle of the left and right clamping claws 43 for positioning and rotation, and the clamping force is maintained by relying on the compression spring 44. On the one hand, it ensures that it can open and clamp the bottle 100 or open and release the bottle 100 when subjected to other external forces. On the other hand, it ensures that the bottle 100 can be stably held during the reciprocating motion of the multi-guide groove variable pitch mechanism 3 and will not fall off.

[0058] Therefore, the working principle of this embodiment is as follows:

[0059] 1. When the bottles 100 are neatly arranged and removed from the bottle blowing machine, the multiple spring clamp mechanisms 4 in the initial position move forward to grab the bottle mouths of the bottles 100 while the alternating telescopic power mechanism 5 works, and at the same time controls the clamps on the bottle blowing machine to move backward to perform synchronous alternation;

[0060] 2. After the bottle 100 is alternately moved, the multi-guide groove pitch-changing mechanism 3 moves laterally with the spring clamp mechanism 4 and the bottle 100 under the drive of the transverse movement power mechanism 2. Since the multi-guide groove pitch-changing mechanism 3 is a double cam structure, the multi-guide groove cam cylinder 32 rotates to perform the pitch-changing action. When the pitch-changing action is completed when the transverse movement reaches the end position, the empty bottle enters the next process. The next process is a track parallel to both sides. After the empty bottle enters the track, other mechanical devices will fix the bottle 100 together with the track, and the alternating telescopic power mechanism 5 moves the spring clamp mechanism 4 backward to release the bottle mouth;

[0061] 3. The multi-guide groove variable pitch mechanism 3 moves laterally back to the initial position, the multi-guide groove cam cylinder 32 rotates to perform a variable pitch action and returns to the initial position, and the multiple spring clamp mechanisms 4 return to the closed state, waiting for the next alternating grasping.

[0062] The above operations are a cycle, which is an endless cycle process in continuous production.

[0063] Therefore, compared with the air duct, the space occupied by the alternating variable pitch bottle transport mechanism of this embodiment is small and will not be blown by the wind. Therefore, this embodiment not only reduces the occupied space, but also can ensure the reliability of the bottle transport alternation, and also ensure that the bottle 100 is as free from contamination as possible before filling, flexibly meeting the food-grade production requirements, and can also meet the high-speed stable continuous production requirements of bottled water.
