Description

Technical Field

[0001] The present invention relates to the technical field of bottle arranging devices, and in particular to an automatic plastic bottle arranging device. Background Art

[0002] Bottle arranging devices are commonly used automated equipment in industries such as bottled water, beverages, and food. They can efficiently arrange plastic bottles and other items that are randomly placed in an orderly manner and convey the neatly arranged bottles to the next process, facilitating subsequent filling and other operations on the plastic bottles. Most bottle arranging devices use a turntable to arrange the bottles. Tooth sockets for accommodating the bottles are provided on the circumference of the turntable. The randomly placed bottles fall into the tooth sockets under the action of an external force. One tooth socket accommodates one bottle. Then, multiple guide rods are used to turn the bottles with their mouths facing downwards, and the bottles with their mouths facing upwards pass through the guide rods normally. Finally, the bottles with the same orientation are output from the turntable to achieve bottle arrangement.

[0003] Currently, the tooth sockets on existing bottle arranging devices are not adjustable. Therefore, the same turntable can only sort bottles within a certain size range. However, since the sizes of plastic bottles vary, it is difficult for existing bottle arranging devices to meet the sorting requirements of bottles of different sizes, and there are certain limitations. Summary of the Invention

[0004] Aiming at the defects existing in the above-mentioned prior art, the purpose of the present invention is to provide an automatic plastic bottle arranging device to solve the problem of being unable to sort more sizes of bottles.

[0005] The purpose of the present invention is achieved by adopting the following technical solutions:

[0006] An automatic plastic bottle arranging device includes a frame. An inclined bottle arranging turntable is provided inside the frame. The bottle arranging turntable includes an upper turntable, a lower turntable, a rotating shaft, a rotating cylinder, and a fastener. The rotating shaft is fixed to the bottom of the upper turntable. A rotating cylinder that can rotate relative to the rotating shaft is sleeved outside the rotating shaft. The lower turntable is fixed on the rotating cylinder and is arranged below the upper turntable. Tooth sockets are provided on the outer circumferences of both the upper turntable and the lower turntable. The upper turntable and the lower turntable can be fixed together through the fastener.

[0007] Further, the bottle arranging turntable includes a connecting cylinder and a plurality of adjusting components. The connecting cylinder is fixed to the bottom of the upper turntable, and a plurality of through holes are provided on the circumferential side surface thereof. The adjusting component includes a movable rod, a steering rod A, a steering rod B, an adjusting block A, and an adjusting block B. A pulley is provided at the inner end of the movable rod, and the pulley abuts against the rotating cylinder. The radius of the outer peripheral surface of the rotating cylinder in contact with the pulley gradually increases. The outer end of the movable rod passes through the through hole and is simultaneously hinged to the steering rod A and the steering rod B. A spring is sleeved on the movable rod, and the spring abuts between the pulley and the connecting cylinder. The outer end of the steering rod A is hinged to the adjusting block A, and the outer end of the steering rod B is hinged to the adjusting block B. The adjusting block A is hinged to the upper turntable, and the adjusting block B is hinged to the lower turntable.

[0008] Further, the number of the adjusting components is the same as the number of the tooth engaging openings on the upper turntable / the lower turntable. The inner side of the adjusting block A is hinged to one side of the tooth engaging opening on the upper turntable, and the inner side of the adjusting block B is hinged to one side of the tooth engaging opening on the lower turntable and is provided on the other side of the tooth engaging opening on the upper turntable.

[0009] Further, the bottle arranging turntable includes a first driving mechanism and a second driving mechanism. The bottom of the rotating shaft passes through the rotating cylinder and is driven by the first driving mechanism. A gear is fixedly sleeved on the lower part of the rotating cylinder, and the second driving mechanism drives the gear. Both the first driving mechanism and the second driving mechanism are arranged in the frame.

[0010] Further, a sleeve is fixed to the top of the rotating cylinder. A guiding ring groove is formed on the outer circumference of the sleeve. The pulley abuts in the guiding ring groove. The top view of the guiding ring groove is an irregular ring shape, and its radius gradually increases along the counterclockwise direction from a specific position. When the tooth engaging openings on the upper turntable and the lower turntable are vertically aligned, it is recorded as the initial state. In the initial state, the lengths of the movable rods of all the adjusting components extending out of the connecting cylinder are the same.

[0011] Further, an inclined bottom plate is fixed in the frame. The bottom plate is arranged below the lower turntable, and the rotating cylinder is rotatably arranged on the bottom plate.

[0012] Further, a first connecting shaft is fixed to the outer end of the movable rod. The steering rod A and the steering rod B are hinged to the movable rod through the first connecting shaft. The steering rod A and the adjusting block A are hinged through a second connecting shaft, and the steering rod B and the adjusting block B are hinged through a third connecting shaft.

[0013] Further, a receiving space is formed above the bottle arranging turntable on the frame. A bottle turning guide rod and a bottle discharging guide rail are arranged inside the frame. The bottle turning guide rod is used for turning the plastic bottle with the bottle mouth facing downward, and the bottle discharging guide rail is arranged above the frame and used for discharging the bottles with the same orientation out of the bottle arranging turntable.

[0014] Further, a partition board is arranged inside the frame. A feeding port is formed on the partition board. A strip-shaped buffer belt is arranged at the top of the feeding port. The partition board divides the frame into left and right chambers. The bottle arranging turntable is arranged in the left chamber. A feeding hopper is arranged at the top of the right chamber, and a conveyor belt is arranged inside. The plastic bottles on the conveyor belt fall from the feeding port to the bottom of the bottle arranging turntable.

[0015] Further, the rotating shaft and the rotating cylinder are connected by a bearing.

[0016] The beneficial effects of the present invention are as follows:

[0017] (1) By arranging the connecting cylinder and the rotating shaft, the independent rotation of the lower turntable is realized. By controlling the rotation angle of the lower turntable, the size of the actual tooth opening is adjusted to adapt to plastic bottles of different sizes.

[0018] (2) By arranging the adjusting assembly, while the lower turntable rotates, the adjusting block A and the adjusting block B are driven to rotate towards the actual tooth opening. On the one hand, the size of the opening position of the actual tooth opening is further reduced to prevent the plastic bottle from shaking greatly at the actual tooth opening and avoid the plastic bottle from tipping over at the position where the upper and lower tooth openings are misaligned. On the other hand, the adjusting block B rotates inward by a larger size than the adjusting block A. The plastic bottle in the actual tooth opening is mainly supported by the partial tooth opening A on the left side of the upper turntable, the partial tooth opening B on the right side of the lower turntable, and the adjusting block B. The larger rotation of the adjusting block B can further ensure the stability of the plastic bottle. Description of the Drawings

Detailed implementation manners

[0031] In order to make the technical problems, technical solutions and beneficial effects solved by the invention clearer and more understandable, the following further describes the invention in conjunction with the drawings and embodiments.

[0032] Embodiment 1

[0033] As Figure 1-10 shown, this embodiment provides a bottle arranging turntable 1, which includes an upper turntable 11, a lower turntable 12, a rotating shaft 13, a rotating cylinder 14 and a fastener 15. A rotating shaft 13 is fixed at the bottom of the upper turntable 11, a rotating cylinder 14 that is rotatable relative to the rotating shaft 13 is sleeved outside the rotating shaft 13, the lower turntable 12 is fixed on the rotating cylinder 14 and is arranged below the upper turntable 11, tooth engaging openings 16 are formed on the outer circumferences of both the upper turntable 11 and the lower turntable 12, and the upper turntable 11 and the lower turntable 12 can be fixed together through the fastener 15.

[0034] The fastener 15 can be fixed by bolts, nuts, etc., for reference Figure 3 and Figure 4 , upper through holes 17 for the fastener 15 to pass through are provided on the upper turntable 11 and the connecting cylinder 111, and lower through holes 18 for the fastener 15 to pass through are also provided on the lower turntable 12. When the fastener 15 fixes the upper turntable 11 and the lower turntable 12 together, the rotating shaft 13 can drive the lower turntable 12 and the upper turntable 11 to rotate simultaneously, thereby realizing bottle alignment. When the fastener 15 is removed from the bottle-aligning turntable 1, the upper turntable 11 and the lower turntable 12 can rotate independently. The upper turntable 11 can be driven by the rotating shaft 13, and the lower turntable 12 can be driven by the rotating cylinder 14. The rotating shaft 13 and the rotating cylinder 14 are connected by two bearings, one above and one below.

[0035] for reference Figure 7 , when the tooth engaging openings 16 on the upper turntable 11 and the lower turntable 12 are vertically aligned, this is recorded as the initial state. In this initial state, the actual tooth opening 110 formed by the upper and lower tooth engaging openings 16 is the largest. For reference Figure 9 , when the upper turntable 11 or / and the lower turntable 12 rotates, the actual tooth opening 110 will become smaller. That is to say, the separate rotation of the upper turntable 11 or the lower turntable 12 can both achieve the change of the actual tooth opening 110. However, in actual operation, since the main function of the rotating shaft 13 is to drive the upper turntable 11 and the lower turntable 12 to rotate simultaneously, it is easier to control the rotation angle by rotating the lower turntable 12 alone, that is, rotating the rotating cylinder 14. Therefore, when adjusting the actual tooth opening 110 in this embodiment, it is preferably achieved by rotating the rotating cylinder 14 and the lower turntable 12.

[0036] for reference Figure 5-10 , the bottle-aligning turntable 1 includes a connecting cylinder 111 and a plurality of adjusting components 19. The connecting cylinder 111 is fixed to the bottom of the upper turntable 11, and a plurality of through holes 112 are provided on the circumferential side surface thereof. The adjusting component 19 includes a movable rod 191, a steering rod A 192, a steering rod B 193, an adjusting block A 194, and an adjusting block B 195. A pulley 196 is provided at the inner end of the movable rod 191, and the pulley 196 abuts against the rotating cylinder 14. The radius of the outer peripheral surface of the rotating cylinder 14 in contact with the pulley 196 gradually increases. The outer end of the movable rod 191 passes through the through hole 112 and is simultaneously hinged to the steering rod A 192 and the steering rod B 193. A spring 197 is sleeved on the movable rod 191, and the spring 197 abuts between the pulley 196 and the connecting cylinder 111. The outer end of the steering rod A 192 is hinged to the adjusting block A 194, and the outer end of the steering rod B 193 is hinged to the adjusting block B 195. The adjusting block A 194 is hinged to the upper turntable 11 through a fourth connecting shaft 1912, and the adjusting block B 195 is hinged to the lower turntable 12 through a fifth connecting shaft 1913.

[0037] A clamping ring 198 is provided at the inner end of the movable rod 191. The clamping ring 198 is arranged outside the pulley 196. The spring 197 is squeezed between the clamping ring 198 and the connecting cylinder 111. The position of the adjusting assembly 19 is limited by the spring 197. Under the limitation of the through hole 112, the radial direction of the rotating cylinder 14 where the movable rod 191 is located will not change. Refer to Figure 9 and Figure 10 , when the rotating cylinder 14 rotates clockwise, the outer peripheral surface of the rotating cylinder 14 in contact with the pulley 196 also rotates accordingly. The radial direction where the pulley 196 is located remains unchanged, and the radius of the outer peripheral surface of the rotating cylinder 14 in contact with the pulley 196 gradually increases. The spring 197 is further compressed, and the length of the movable rod 191 extending out of the connecting cylinder 111 changes. Under the multi-articulated relationship, the rotation directions of the adjusting block A194 and the adjusting block B195 change. Specifically, when the rotating cylinder 14 rotates, it will drive the lower turntable 12 to rotate together. When the actual tooth opening 110 changes, the adjusting block A194 and the adjusting block B195 rotate synchronously towards the actual tooth opening 110, further reducing the size of the opening position of the actual tooth opening 110.

[0038] Refer to Figure 9 , from a top view perspective, the actual tooth opening 110 is composed of a partial clamping tooth opening A113 on the left side of the upper turntable 11 and a partial clamping tooth opening B114 on the right side of the lower turntable 12. In fact, the adjusting block A194 and the adjusting block B195 are supplemented at the position where the upper and lower clamping tooth openings 16 are misaligned. Under the guidance of the adjusting block A194 and the adjusting block B195, the plastic bottle will not contact the clamping tooth opening 16 outside the actual tooth opening 110, that is, it will not contact the partial clamping tooth opening 16 on the right side of the upper turntable 11 and the partial clamping tooth opening 16 on the left side of the lower turntable 12, preventing the plastic bottle from shaking greatly at the actual tooth opening 110 and avoiding the plastic bottle from tipping over at the position where the upper and lower clamping tooth openings 16 are misaligned. In addition, since the adjusting block B195 is articulated to the lower turntable 12 and will rotate together with the lower turntable 12, the adjusting block B195 will rotate inward by a larger size relative to the adjusting block A194. When the plastic bottle is at the actual tooth opening 110, it is mainly supported by the partial clamping tooth opening A113 on the left side of the upper turntable 11, the partial clamping tooth opening B114 on the right side of the lower turntable 12, and the adjusting block B195. Therefore, the larger rotation of the adjusting block B195 further ensures the stability of the plastic bottle.

[0039] The number of the adjusting components 19 is the same as that of the tooth engaging openings 16 on the upper turntable 11 / lower turntable 12 and they correspond one by one. The inner side of the adjusting block A194 is hinged to one side of the tooth engaging opening 16 on the upper turntable 11. The inner side of the adjusting block B195 is hinged to one side of the tooth engaging opening 16 on the lower turntable 12 and is arranged on the other side of the tooth engaging opening 16 on the upper turntable 11. The two adjusting blocks are arranged near the tooth engaging opening 16, which is more convenient for adjusting the size of the actual tooth opening 110 at the opening position. The two adjusting blocks extend out of the upper turntable 11 and the lower turntable 12, which can increase the surrounding area of the plastic bottle and the actual tooth opening 110, limit the plastic bottle in the actual tooth opening 110, and prevent the plastic bottle from tilting and escaping from the actual tooth opening 110 easily.

[0040] The bottle arranging turntable 1 includes a first driving mechanism and a second driving mechanism. The bottom of the rotating shaft 13 penetrates through the rotating cylinder 14 and is driven by the first driving mechanism. A gear 115 is fixedly sleeved on the lower part of the rotating cylinder 14, and the second driving mechanism drives the gear 115. Both the first driving mechanism and the second driving mechanism are arranged in the frame 2.

[0041] Due to the multi-hinged relationship of the adjusting components 19, when the movable rod 191 expands and contracts by a very small length, the adjusting block A194 and the adjusting block B195 can have a relatively obvious angular rotation. By setting the gear 115 and adjusting the rotation speed of the rotating cylinder 14, the rotation angle of the lower turntable 12 can be adjusted more precisely.

[0042] A sleeve 116 is fixed at the top of the rotating cylinder 14. A guiding ring groove 117 is formed on the outer periphery of the sleeve 116. The pulley 196 abuts against the guiding ring groove 117 and can only move within the guiding ring groove 117. The pulley 196 is limited in the guiding ring groove 117, and is more stable and accurate in position when sliding. The top view of the guiding ring groove 117 is an irregular ring, and its radius gradually increases in the counterclockwise direction from a specific position. In the initial state, the lengths of the movable rods 191 of all the adjusting components 19 extending out of the connecting cylinder (111) are the same, ensuring the consistency of the adjusting blocks.

[0043] A first connecting shaft 199 is fixed at the outer end of the movable rod 191. The steering rod A192 and the steering rod B193 are hinged to the movable rod 191 through the first connecting shaft 199. The steering rod A192 and the adjusting block A194 are hinged through a second connecting shaft 1910. The steering rod B193 and the adjusting block B195 are hinged through a third connecting shaft 1911.

[0044] Embodiment 2

[0045] As Figure 1-11As shown in the figure, this embodiment provides an automatic plastic bottle sorting device, which includes a frame 2. Inside the frame 2, there is an inclined sorting turntable 1 of Embodiment 1. Above the sorting turntable 1 in the frame 2, there is an accommodation space. Inside the frame 2, there are bottle-turning guide rods 3 and a bottle outlet guide rail 4. The position of the bottle-turning guide rods 3 is adjustable, and there is more than one bottle-turning guide rod 3, which is used to turn the plastic bottles with their mouths facing down. This belongs to the prior art. The bottle outlet guide rail 4 is arranged above the frame 2 and is used to export the bottles with the same orientation from the sorting turntable 1.

[0046] Inside the frame 2, there is a partition 5. On the partition 5, there is a feed inlet 6. At the top of the feed inlet 6, there is a strip-shaped buffer belt 7. The partition 5 divides the frame 2 into left and right chambers. The sorting turntable 1 is arranged in the left chamber. At the top of the right chamber, there is a feed hopper 8, and inside there is a conveyor belt 9.

[0047] Inside the frame 2, there is a fixed inclined bottom plate 10. The bottom plate 10 is arranged below the lower turntable 12. The rotating cylinder 14 is rotatably arranged on the bottom plate 10.

[0048] Working principle:

[0049] When the size of the plastic bottle is large, the sorting of the plastic bottle is achieved by aligning the upper turntable 11 and the lower turntable 12 with their upper and lower engaging openings 16. At this time, the size of the engaging opening 16 is the size of the actual tooth opening 110. There is no need to rotate the rotating cylinder 14, and the upper turntable 11 and the lower turntable 12 are directly fixed together with the fastener 15. When the size of the plastic bottle changes, according to the actual size of the plastic bottle, the rotation angle of the rotating cylinder 14 is adjusted. Specifically, the fastener 15 is removed, the second driving mechanism drives the gear 115, the rotating cylinder 14 rotates, driving the lower turntable 12 and the sleeve 116 at the top to rotate together. On the one hand, the lower turntable 12 rotates a specific angle, and the upper and lower engaging openings 16 are staggered to form the actual tooth opening 110. At the same time, the lower turntable 12 drives the third connecting shaft 1911 to move. On the other hand, the irregular annular sleeve 116 rotates, and the movable rod 191 extends out a specific length. Under the multi-articulated relationship, the adjusting block A194 and the adjusting block B195 rotate inward by a specific angle, reducing the size of the opening position of the actual tooth opening 110, making it difficult for the plastic bottle to escape from the actual tooth opening 110. At the same time, since the adjusting block B195 is articulated on the lower turntable 12 and will rotate with the lower turntable 12, the adjusting block B195 will rotate inward by a larger angle to prevent the plastic bottle from leaning towards the engaging opening 16 on the right side of the upper turntable 11 and avoid the plastic bottle from tipping over during rotation. Then, the upper turntable 11 and the lower turntable 12 are fixed together with the fastener 15, and the bottle-turning guide rod 3 is replaced or adjusted.

[0050] Then the first driving mechanism drives the rotating shaft 13, and the rotating shaft 13 drives the upper turntable 11 and the lower turntable 12 to rotate together, pouring the messy plastic bottles from the feed hopper 8 onto the conveyor belt 9. The plastic bottles on the conveyor belt 9 fall from the feed port 6 to the bottom of the bottle arranging turntable 1. Under the beating of the rotating wheel bars, which are not drawn, the plastic bottles at the bottom of the bottle arranging turntable 1 are continuously beaten and vibrate together, gradually falling into the actual tooth openings 110 at the bottom. The plastic bottles are gradually driven by the bottle arranging turntable 1. During the rotation process, the plastic bottles with their mouths facing down are flipped by the bottle turning guide rod 3, and finally are led out of the bottle arranging turntable 1 by the bottle outlet guide rail 4.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
