Description

Technical Field

[0001] This invention belongs to the field of empty bottle handling technology, and in particular relates to an automatic bottle turning device. Background Technology

[0002] Cleaning bottles and containers before filling is a crucial step in ensuring product quality, safety, and compliance. Its main purposes are to remove contaminants, guarantee product quality, meet regulatory standards, and extend shelf life.

[0003] Therefore, for the production of liquid products, the cleaning of empty bottles is crucial to ensuring product quality. To improve the cleaning of empty bottles, existing technologies often focus on improving the cleaning techniques for empty bottles on filling production lines. For example, Chinese Patent Application No. CN202422399051.8 discloses a cleaning and drying device for beverage filling bottles. The key technical points of this device are: a transverse movement mechanism; a lifting mechanism on the transverse movement mechanism; a flipping and gripping mechanism on the lifting mechanism; a bottle feeding mechanism on one side of the flipping and gripping mechanism; and a cleaning mechanism and a drying mechanism on the other side of the flipping and gripping mechanism. This application can thoroughly rinse the inner wall of the filling bottle and, after cleaning, dry the inside of the bottle, preventing the bottle from remaining damp for extended periods and breeding bacteria.

[0004] However, during the washing process, the bottles are positioned with their necks facing inwards in the clamps. After washing, to ensure thorough drainage, the bottles are fed upside down onto the conveyor line from the washing machine. The conveyor line is equipped with molds for holding these inverted empty bottles. The bottles then need to be flipped over so that their necks are facing upwards before being fed back onto the conveyor line, awaiting subsequent filling.

[0005] Currently, turning an inverted bottle into an upright position can only be done manually, which is not only inefficient but also physically demanding and tiring for workers.

[0006] Therefore, adjusting the posture of empty bottles after cleaning (i.e., turning over bottles) has become one of the factors that seriously affect production efficiency during the production process.

[0007] Meanwhile, in actual production, different filling products often need to share a single production line. Therefore, when the production line processes empty bottles of different sizes, the bottle shapes of these different sizes often vary considerably. Although existing technologies use some flipping structures to flip the bottles, traditional bottle-flipping structures have many drawbacks when encountering production lines with high automation requirements, such as poor versatility, low efficiency, and incompatibility with automated production lines.

[0029] The realization of the purpose, functional features and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0032] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0033] Example 1 like Figure 1-12 As shown, an automatic bottle-turning device includes a first conveyor line 1 for conveying cleaned bottles, and a second conveyor line 3 inside the first conveyor line 1. Cleaned bottles 6 (bottles 6 unloaded from the bottle washing machine) are fed onto the first conveyor line 1 in an inverted position (the first conveyor line 1 is equipped with a mold for inverting and installing empty bottles). The empty bottles are picked up by the following bottle-grabbing mechanism and flipped from the inverted position to the normal position before being fed onto the second conveyor line 3. The second conveyor line 3 then transports the empty bottles to the subsequent filling section.

[0034] Because the inverted bottle 6 is difficult to flip and adjust, this invention improves upon it by providing a bottle-gripping mechanism that is highly efficient, versatile, and compatible with various bottle models 6, in order to work with a high-efficiency automated production line. The bottle-gripping mechanism is located inside the second conveyor line 3.

[0035] The bottle-grabbing mechanism includes a bottle-grabbing robot 1 and a bottle-flipping robot 5 that work together (similar to existing methods, the bottle-grabbing robot 1 and the bottle-flipping robot 5 are mounted on a vehicle body to move the entire device); after the bottle-grabbing robot 1 picks up the inverted bottle 6 from the first conveyor line 1, it adjusts the position of the bottle 6 so that the bottle mouth faces the bottle-flipping robot 5. After the bottle-flipping robot 5 picks up the bottle 6, it adjusts the position and then lowers the bottle 6 onto the second conveyor line 3 with the bottle mouth facing upward.

[0036] By developing and improving the bottle-grabbing robot 1 and the bottle-flipping robot 5, the technical bottleneck of difficulty in flipping empty bottles after cleaning has been solved.

[0037] Example 2 like Figure 1-12 As shown, this embodiment discloses the specific structure of the bottle-grabbing robot 1 based on the structure of embodiment 1.

[0038] Specifically, the bottle-grabbing robot 1 includes a robotic arm 12 (the robotic arm 12 is a conventional industrial robotic arm 12 for industrial production operations disclosed in the prior art), and the operating end of the robotic arm 12 is equipped with a flip-up bottle-suction gripper 11.

[0039] like Figure 13 , Figure 14 As shown, specifically, the bottle suction clamp 11 includes a clamp body 111 (the clamp body 111 is a vacuum sponge clamp, the bottom of which has a guiding part 1112 to guide the bottle to be suctioned, and at the same time, the sponge clamp controls the opening and closing size of the suction port through an adaptive vacuum opening and closing valve 1111 to ensure that the bottle is suctioned with appropriate suction force). The top of the clamp body 111 is equipped with a first tilting cylinder 112, which is installed at the operating end of the robotic arm 12.

[0040] Specifically, the first tilting cylinder 112 is a 90-degree tilting cylinder disclosed in the prior art. Its tilting principle is as follows: the piston rod of the first tilting cylinder 112 is hinged to the top of the clamp body 111, which is then hinged to the bracket on which the cylinder barrel of the first tilting cylinder 112 is fixedly mounted (the piston rod is slidably connected to the bracket and passes through it before being hinged to the clamp body 111). When the first tilting cylinder 112 pushes the piston rod to extend or retract, the hinged piston rod pushes the clamp body 111 to tilt.

[0041] Therefore, during the operation, the suction end of the clamp body 111 is first vertically oriented towards the inverted bottle 6 on the first production line (cleverly utilizing the fact that the bottle 6 is inverted after cleaning, with the bottom facing up, and the bottom area is large, so a suction cup is used to grip it. For most bottles 6, the large bottom area allows the bottle gripping robot 1 to universally grip various types of bottles 6).

[0042] The gripper body 111 picks up the bottom of the inverted empty bottle, and then the robotic arm 12 adjusts its posture and flips it over with the gripper body 111 so that the bottle opening faces the bottle-flipping robot 5 to wait for the bottle-flipping operation.

[0043] Example 3 like Figure 1-12 As shown, this embodiment discloses the structure of the bottle-flipping robot 5 based on the structure of embodiment 2.

[0044] Specifically, the bottle-turning machine 5 includes a bottle-clamping fixture 51 that receives bottles 6 from the bottle suction fixture 11, and a drive mechanism 52 that drives the bottle-clamping fixture 51 to complete the bottle-grabbing and bottle-releasing actions.

[0045] Specifically, the drive mechanism 52 includes a frame 521, on which a slide structure for driving the bottle clamp 51 to lift and translate is installed (i.e., to achieve X / Z dual-axis movement).

[0046] The bottle-grabbing and bottle-placing process is achieved through the slide structure. This requires adjusting the bottle clamp 51 (the neck of the bottle 6 is clamped on the bottle clamp 51) and the height of the empty bottle. When the optimal bottle-placing height is adjusted, the bottle 6 on the clamp is lowered. At the same time, horizontal movement is achieved to facilitate receiving the empty bottle on the suction bottle clamp 11.

[0047] This structural design enables a series of actions to be completed, ensuring the stability of grasping, flipping, and placing the bottle, while avoiding damage to the bottle during operation.

[0048] Specifically, the carriage structure includes a vertical carriage 525 slidably connected to the frame 521, and the vertical carriage 525 is driven to rise and fall by a first synchronous belt structure 522.

[0049] like Figure 8 As shown, the vertical carriage 525 includes a main frame set by a vertical frame 521. The left and right ends of the main frame are respectively fixedly connected to the first slide block 5251. Correspondingly, the left and right sides of the frame 521 are fixedly installed with the first slide rail 5211 that is slidably connected to the first slide block 5251.

[0050] like Figure 4-5 As shown, the first synchronous belt structure 522 includes a dual-axis motor 5221 fixedly installed at the lower end of the frame 521 (a motor bracket is fixedly installed at the bottom of the dual-axis motor 5221, and the motor bracket is fixed on the frame 521), and lower synchronous pulleys 5222 are fixedly installed on the output shafts at both ends of the dual-axis motor 5221 respectively.

[0051] like Figure 5-6 As shown, the top (front end) of the corresponding main frame is rotatably connected to the upper synchronous pulley 5224, which is connected to the lower synchronous pulley 5222 via the first synchronous belt 5223 (specifically, the upper synchronous pulley 5224 is rotatably connected to a wheel bracket, which is fixed on the main frame).

[0052] like Figure 8 As shown, the first synchronous belt 5223 is fixedly installed on the main frame, and the fixed position is shown in position B in the figure.

[0053] The first synchronous belt 5223 and the upper and lower synchronous pulleys 5222 are meshed, that is, the upper and lower synchronous pulleys 5222 have meshing synchronous pulley tooth groove structures that mesh with the convex tooth structure on the synchronous belt. This method increases the stability of the transmission.

[0054] During the lifting process, driven by the two first synchronous belts 5223, the dual-axis motor 5221 pulls the vertical slide 525 up and down by rotating in both directions, and the bottle clamp 51 installed on the vertical slide 525 follows the lifting and lowering.

[0055] The above-mentioned lifting structure design not only has high stability and great lifting flexibility, but also has higher precision in synchronous belt lifting.

[0056] The height of the bottle clamp 51 can be adjusted by lifting and lowering to achieve the posture of receiving the bottle 6, rotating and flipping the bottle 6, and lowering the bottle 6.

[0057] Example 4 like Figure 1-12 As shown, based on the structure of embodiment 3, this embodiment requires adjusting the horizontal displacement of the bottle clamp 51 during the process of receiving the bottle 6, rotating and flipping the bottle 6, and lowering the bottle 6. Therefore, the top of the vertical slide 525 is slidably connected to the horizontal slide 5234.

[0058] like Figure 4 As shown, the horizontal carriage 5234 is driven to move horizontally via the second synchronous belt structure 523. The bottle clamp 51 is mounted on the horizontal carriage 5234.

[0059] A second slide rail is fixedly connected to the top of the main frame, and correspondingly, a second slide block is fixedly connected to the bottom of the horizontal slide 5234 and slidably connected to the second slide rail.

[0060] like Figure 6-7 As shown, the second synchronous belt structure 523 includes an outer synchronous belt pulley 5231 rotatably connected to the outer side of the top of the main frame (rear end position). Similarly, a synchronous belt motor 5233 is installed on the inner side of the main frame, and an inner synchronous belt pulley 5232 is fixedly installed on the output shaft of the synchronous belt motor 5233, which is connected to the outer synchronous belt pulley 5231 via the second synchronous belt drive (similarly, the synchronous belt motor 5233 is fixedly installed on the main frame via a motor bracket).

[0061] like Figure 8 As shown, the second synchronous belt is fixed on the horizontal carriage 5234, specifically at point A in the figure.

[0062] The second synchronous belt described above has the same structure as the first synchronous belt 5223 522 described above, and engages with the inner and outer synchronous pulleys 5231 in the same way.

[0063] During operation, when it is necessary to move the bottle clamp 51-empty bottle horizontally, the horizontal slide 5234 is driven to slide along the second slide rail under the forward and reverse drive of the synchronous belt motor 5233, so as to adjust the horizontal position and posture of the bottle clamp 51-empty bottle.

[0064] Example 5 like Figure 1-12As shown, in this embodiment, based on the structure of embodiment 4, after the bottle clamp 51 picks up the empty bottle from the clamp body 111, in order to adjust the posture of the bottle body by flipping it over and preparing to place the bottle body down on the second transmission line in a normal posture, the bottle clamp 51 also adopts a flipping structure to flip it over.

[0065] like Figure 7 As shown, specifically, cylinder supports 52341 are fixedly installed at both ends of the horizontal slide 5234, and second tilting cylinders 524 are fixedly installed at the bottom of the cylinder supports 52341. The bottle clamping fixture 51 is installed at the pushing end of the second tilting cylinder 524. Similarly, the second tilting cylinder 524 is also a 90-degree tilting cylinder disclosed in the prior art, and its tilting structure principle is the same as that of the existing first tilting cylinder 112.

[0066] Specifically, the bottle clamp 51 includes a clamp fixing bracket 512, with mounting seats 514 fixedly installed at both ends of the clamp fixing bracket 512 (a pair of mounting arms are welded to the inner side of the mounting seat 514, the mounting arms are fixed on the clamp fixing bracket 512, and the mounting arms have notches to accommodate the passage of the third track described below). The pushing end of the second tilting cylinder 524 is hinged to an assembly seat that fixes the mounting seat 514. The assembly seat and the mounting seat 514 are fixedly connected by bolts.

[0067] Because of the flip-type connection, the mounting base is hinged to the bracket 5241 on which the cylinder barrel of the second flip cylinder 524 is fixedly mounted (hinged by a pin). Similarly, the piston rod of the second flip cylinder 524 is hinged to the hinge tongue welded on the mounting base.

[0068] During the flipping process, as the second flipping cylinder 524 pushes the piston rod to extend and retract, it pushes the bottle clamp 51 to flip.

[0069] During horizontal movement and vertical lifting, the horizontal slide 5234 carries the bottle clamp 51 and the second tilting cylinder 524 in coordination.

[0070] Example 6 like Figure 1-12 As shown, based on the structure of embodiment 5, this embodiment discloses the specific structure of the bottle clamp 51 in order to achieve the one-time gripping of two rows of bottles 6 on the first conveyor line 1.

[0071] Specifically, a gripper structure is slidably mounted on the clamp fixing bracket 512. The gripper structure includes a fixed gripper part and a movable gripper part. During operation, the fixed gripper part remains stationary, while the movable gripper part, pushed by the following push cylinder, moves towards the fixed gripper part to grasp the bottle, and moves away to release the bottle 6.

[0072] Therefore, the movable claw is driven by the cylinder to cooperate with the fixed claw.

[0073] Specifically, the fixed claw portion includes several fixed claws 5121 fixedly connected to the clamp fixing bracket 512 (the fixing bracket has a claw mounting seat integrally formed for mounting the fixed claws 5121). Similarly, the movable claw portion includes several movable claws 5111 that cooperate with the fixed claws 5121 (similarly, the claw seat for mounting the movable claws 5111 is fixedly mounted on the push bracket 511 described below).

[0074] To grip the bottle neck, the fixed claw 5121 and the movable claw 5111 each have a pair of interlocking slots (arc-shaped) spaced apart vertically on their opposite sidewalls. When the fixed claw 5121 and the movable claw 5111 approach each other, the slots close together and lock onto the bottle neck; conversely, they release the bottle when they move apart.

[0075] Specifically, push brackets 511 are fixedly connected between the top and bottom of the movable claws 5111, and push cylinders 513 for pushing the push brackets 511 are fixedly installed on the clamp fixing bracket 512. Specifically, a pair of spaced U-shaped connecting brackets 5112 are fixedly installed between the push brackets 511, and a third slide block 5131 is fixedly connected to each U-shaped connecting bracket 5112. Correspondingly, a third track for slidingly connecting the third slide block 5131 is fixedly connected to the clamp fixing bracket 512.

[0076] A mutually cooperating push cylinder 513 is installed on each U-shaped connecting frame 5112. The piston rod of the push cylinder 513 is fixed on the U-shaped connecting frame 5112, and the cylinder barrel is fixed with a cylinder barrel mounting bracket. The cylinder barrel mounting bracket is L-shaped and is fastened to the clamp fixing bracket 512 by bolts.

[0077] During operation, with the cooperation of the push cylinder 513 (the two push cylinders 513 push in opposite directions), one push cylinder 513 pushes while the other push cylinder 513 retracts its piston rod to pull, thereby driving the movable claw 5111 to slide along the third track, so that the movable claw 5111 approaches the fixed claw 5121 and extends into the neck of the bottle to lock and fix the bottle 6.

[0078] The above structure firstly enables the simultaneous grabbing of two rows of empty bottles. Secondly, it enables the grabbing of bottles of different sizes (with different neck diameters) during operation. Thirdly, the fixed claw 5121 and the movable claw 5111 are fixed by bolts, making them replaceable.

[0079] The purpose of the above structure design is: 1. Based on the fact that the bottles are fed onto the conveyor line in a double-row manner after cleaning, the double rows can be grabbed at once; 2. During the filling and conveying process, bottles 6 are filled in a single row. Therefore, in conjunction with the following merging and pushing bottle assembly, during the lowering of bottles 6, one row of bottles 6 is located on the second conveyor line, and the other row of bottles 6 is pushed onto the second conveyor line by the merging and pushing bottle assembly. This ensures that the bottle grabbing volume is guaranteed and avoids untimely material grabbing and congestion defects, while also realizing the final formation of bottles 6 from two rows into a single row of bottles for conveying.

[0080] Example 7 like Figure 1-12 As shown, this embodiment, based on the structure of embodiment 6, specifically discloses the specific structure of the confluence and bottle pushing assembly 4.

[0081] Specifically, the confluence bottle pusher assembly 4 includes a fixed bracket that is fixedly installed on the frame 521 of the second conveyor line 3. A cylinder 41 is installed on the fixed bracket. A bottle pusher 42 that pushes the bottle toward the second conveyor line 3 is installed on the piston rod of the cylinder 41. The bottle pusher 42 is slidably connected to the fixed bracket (a slide rail is fixed at each end of the side wall of the bottle pusher 42) via a slide rail.

[0082] Specifically, the bottle pusher is L-shaped. Meanwhile, a stacking plate 43 for placing another row of bottles 6 is fixed on the inner side of the frame 521 of the second conveyor line 3. During the process of the bottle clamp 51 lowering the bottles 6, one row of bottles 6 is lowered to the second conveyor line 3 and taken away, while another row is placed on the stacking plate 43. After the front row of bottles 6 has completely left, the cylinder 41 pushes the bottle pusher 42 to push the other row of bottles 6 to the second conveyor line 3.

[0083] Example 8 like Figure 1-10 As shown, in this embodiment, based on the structure of embodiment 7, the cleaned bottle 6 is fed onto the first conveyor line 1. Therefore, in order to further dry the bottle 6, the first conveyor line 1 is equipped with an air knife assembly 21, which blows away the water droplets and accumulated water on the empty bottle. The air knife assembly includes an air knife bracket 211 installed on the frame 521 of the first conveyor line 1, and a plurality of air knives 212 are installed on the air knife bracket 211.

[0084] Similar to existing methods, the air knife 212 is connected to the high-pressure air circuit system, and the high-pressure airflow generated by the high-pressure air pump on the high-pressure air circuit system dries the bottle 6.

[0085] Example 9 like Figure 1-12 As shown, in this embodiment, based on the structure of embodiment 8, when the bottle 6 is fed to the second conveyor line 3 in the above manner and transported to the filling section, in order to straighten the bottle 6 and ensure that the filling equipment can accurately fill the solution into the bottle, a bottle guiding component 31 is installed at the discharge end of the second conveyor line 3.

[0086] Specifically, the bottle guiding component 31 includes a mounting bracket 314 fixedly installed on the frame 521 of the second conveyor line 3. A guiding bracket 312 is hinged to the top of the mounting bracket 314 (a support 311 is fixedly installed on the top of the mounting bracket 314, and the end of the guiding bracket 312 is hinged to the support 311 by a pin, which is fixed to the support 311). During the transmission of the wine bottle on the second conveyor line 3, the posture of the bottle is corrected by the guiding bracket.

[0087] Simultaneously, the bottle posture needs to be adjusted during the calibration process. Therefore, the aforementioned mounting bracket 314 is equipped with an adjusting rod 313 for adjusting the flipping angle of the guide bracket. The adjusting rod 313 abuts against the inner side of the guide bracket 314. That is, when the adjusting rod 313 pushes the guide bracket 314 forward, the guide bracket 314 flips and flips towards the inner side of the second conveyor line 3. A channel for empty bottles to pass through is formed between the guide bracket 314 and the frame 521 of the second conveyor line 3. Since the angle of the guide bracket 314 is adjustable, the size of the channel can be adjusted, thus ensuring that empty bottles can pass through the channel and that the empty bottles are aligned.

[0088] Simultaneously, it can be adjusted to accommodate different bottle sizes. Specifically, the adjusting rod 313 is slidably connected to the fixed vertical end of the support top and threaded with a pair of positioning nuts. Loosening the positioning nuts allows the adjusting rod to slide and adjust. After adjusting the distance between the adjusting rod and the guide bracket 312, the flip angle of the guide bracket 312 is changed, thereby adjusting the size of the channel.

[0089] Of course, the above description is not intended to limit the present invention, nor is the present invention limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
