Description

Technical Field

[0001] The present invention relates to the technical field of packing and turning, and in particular to a turning device for packing components of different specifications. Background Art

[0002] Turning devices are widely used in the field of product packing in many industries. After the components are produced, they are turned onto the fitting parts through the turning device for subsequent packing. When packing products or components, components of different specifications and sizes are often encountered, resulting in a low application range of the turning device. When most of the existing turning devices are used and the assembled components are turned more than 90 degrees, they will be subjected to an instantaneous downward force, which will suddenly accelerate the turning speed of the turning device and easily cause damage to the turning device, thus reducing the service life of the turning device and making it very inconvenient to use. The specifications and heights of the conveyor devices used in each factory are very different, and the specifications of most of the existing common turning devices are mostly fixed and cannot cooperate with different conveyor devices, resulting in a low application range of the turning device. For this reason, a turning device for packing components of different specifications is proposed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies existing in the prior art, and a turning device for packing components of different specifications is proposed.

Both the front and rear sides of the upper part of the base are fixedly connected with brackets. On the outside of one bracket, a reduction motor is fixedly connected. The output end of the reduction motor penetrates through the bracket housing and is fixedly connected with a driving gear. The driving gear is rotatably connected to the lower part inside the bracket. In the middle of the bracket, a connecting gear is rotatably connected. Above the bracket, a driven gear is rotatably connected. The lower side of the connecting gear meshes with the driving gear, and the upper side of the connecting gear meshes with the driven gear. In the middle of the connecting gear, a rotating shaft is fixedly connected. The rotating shaft penetrates through the middle of the bracket and rotates in the middle of the bracket. In the middle of the driven gear, a polygonal sliding rod is fixedly connected. The polygonal sliding rod penetrates through the upper part of the bracket and rotates in the upper part of the bracket. On one side of the middle of the polygonal sliding rod, a two-way electric push rod is fixedly connected. Two sliders are slidably connected to the outer periphery of the polygonal sliding rod. The two ends of the two-way electric push rod are respectively fixed on the opposite sides of the sliders. On the left side of the slider, an insertion rod is fixedly connected. The first conveyor device is located on the left side of the base. A component body is arranged on the upper part of the first conveyor device. The storage platform is located on the right side of the base. The third conveyor device is located on the right side of the storage platform.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figures 1-5, an embodiment provided by the present invention: A turnover device for packing components of different specifications, including a first conveyor 1, a second conveyor 2, a storage table 3, a third conveyor 4 and a base 7. Both the front and rear sides of the upper part of the base 7 are fixedly connected with brackets 8. A reduction motor 9 is fixedly connected to the outside of one bracket 8. The output end of the reduction motor 9 penetrates through the housing of the bracket 8 and is fixedly connected with a driving gear 21. The driving gear 21 is rotatably connected to the lower part inside the bracket 8. A connecting gear 22 is rotatably connected to the middle part inside the bracket 8. A driven gear 23 is rotatably connected to the upper part inside the bracket 8. The lower side of the connecting gear 22 meshes with the driving gear 21, and the upper side of the connecting gear 22 meshes with the driven gear 23. Specifically, the component body 5 is an elevator car bottom component in the embodiment. When the inserting rod 11 enters the jack in the middle of the component body 5, the reduction motor 9 works to drive the driving gear 21 to rotate, and then the connecting gear 22 makes the driven gear 23 rotate, thereby driving the polygonal slide bar 17 to rotate, driving the inserting rod 11 to turn over, so that the component body 5 rotates along the circumference of the polygonal slide bar 17, and thus the component body 5 falls on the wooden bracket 6 on the storage table 3. By making the rollers on the storage table 3 rotate, the wooden bracket 6 and the component body 5 are driven to move towards the third conveyor 4, and the component body 5 is moved to the next link through the third conveyor 4. A rotating shaft 15 is fixedly connected to the middle of the connecting gear 22. The rotating shaft 15 penetrates through the middle of the bracket 8 and rotates in the middle of the bracket 8. A polygonal slide bar 17 is fixedly connected to the middle of the driven gear 23. The shape of the polygonal slide bar 17 makes the connection between the slider 10 and the polygonal slide bar 17 more stable, preventing the slider 10 from not rotating when the polygonal slide bar 17 rotates, and ensuring the normal operation of the turnover device. The polygonal slide bar 17 penetrates through the upper part of the bracket 8 and rotates in the upper part of the bracket 8. A two-way electric push rod 12 is fixedly connected to one side of the middle of the polygonal slide bar 17. The two-way electric push rod 12 refers to the two-way electric push rod 12 disclosed in a two-way synchronous telescopic electric push rod with the patent publication number CN207234607U. Through the two-way electric push rod 12, it is adjusted according to the position of the jack in the middle of the component body 5, so that the slider 10 drives the inserting rod 11 to move on the polygonal slide bar 17, aligning the slide bar with the jack. Then the first conveyor 1 drives the component body 5 to the right, so that the inserting rod 11 enters the jack. Two sliders 10 are slidably connected to the outer periphery of the polygonal slide bar 17. Both ends of the two-way electric push rod 12 are respectively fixed to the opposite sides of the sliders 10. The two-way electric push rod 12 drives the sliders 10 to move, so that the position of the inserting rod 11 can be adjusted according to the size of the component body 5 of different specifications, thereby increasing the applicable range of the turnover device. An inserting rod 11 is fixedly connected to the left side of the slider 10. The first conveyor 1 is located on the left side of the base 7. The component body 5 is arranged on the upper part of the first conveyor 1. The component body 5 is conveyed to the turnover device through the first conveyor 1. The storage table 3 is located on the right side of the base 7. The third conveyor 4 is located on the right side of the storage table 3. The second conveyor 2 is located on the front side of the storage table 3.There is a wooden bracket 6 arranged above the storage table 3. The second conveying device 2 conveys the wooden bracket 6 to the storage table 3 and keeps it stationary. After the component body 5 is flipped onto the wooden bracket 6, the rollers on the storage table 3 rotate, driving the wooden bracket 6 and the component body 5 to move towards the third conveying device 4. The component body 5 is moved to the next process through the third conveying device 4. There is a photoelectric induction sensor 24 on the storage table 3 for positioning the wooden bracket 6. The precise positioning of the wooden bracket 6 is achieved through the mutual cooperation of the photoelectric induction sensor 24 and an external controller. The photoelectric induction sensor 24 is a structure of the prior art and will not be elaborated here.,

[0031] A baffle 13 is fixedly connected to the upper part of the insertion rod 11 near the two-way electric push rod 12 to limit the position of the component body 5 and prevent damage during flipping caused by the component body 5 being too close to the flipping mechanism. Four telescopic cylinders 14 are fixedly connected to the periphery of the middle part of the base 7. Anti-slip pads are provided at the bottom of the telescopic cylinders 14. When cooperating with the first conveyor device 1 of different specifications and heights, the telescopic cylinders 14 can be driven to work to move the whole device up and down, and it can cooperate with the first conveyor device 1 of different specifications to increase the application range of the device. Universal wheels are fixedly connected to the periphery of the bottom of the base 7. When the device needs to be moved, the base 7 can be lowered by the telescopic cylinders 14, so that the universal wheels are in contact with the ground, and the whole flipping device can be moved by the universal wheels, which is more convenient to use. Cam 18 is fixedly connected to the outer periphery of both the left and right sides of the polygonal slide rod 17. A mounting seat 16 is fixedly connected to the middle part of the upper side of the base 7. A tension spring 20 is provided on one side of the mounting seat 16. One end of the tension spring 20 is fixedly connected to the upper part of the base 7, and the other end of the tension spring 20 is fixedly connected to a brake belt 19. The end of the brake belt 19 away from the tension spring 20 bypasses the outer periphery of the cam 18 and is fixedly connected to the upper side of the mounting seat 16. When the reduction motor 9 drives the insertion rod 11 to rotate, the cam 18 rotates synchronously. When the insertion rod 11 rotates more than 90 degrees, the cam 18 contacts the bottom of the brake belt 19, and the cam 18 pulls the brake belt 19. Under the action of the tension spring 20, the friction between the brake belt 19 and the cam 18 is increased, so as to decelerate the insertion rod 11 and prevent damage to the reduction motor 9 caused by the instantaneous downward force when the insertion rod 11 drives the component body 5 to rotate more than 90 degrees. At the same time, during the first 90-degree flipping, the flipping speed can be maintained, and the flipping efficiency can be further improved. The diameter of the connecting gear 22 is larger than that of the driving gear 21, and the diameter of the driven gear 23 is smaller than that of the connecting gear 22. When the reduction motor 9 drives the polygonal slide rod 17 to flip, the connecting gear 22 restricts the driven gear 23. When the insertion rod 11 and the component body 5 flip more than 90 degrees, the connecting gear 22 limits the polygonal slide rod 17 to prevent damage to the reduction motor 9 caused by the instantaneous downward force received by the component body 5 and the insertion rod 11, ensure the normal use of the device, and improve the service life of the device. The protruding part of the cam 18 contacts the inner surface of the brake belt 19 when the insertion rod 11 rotates more than 90 degrees, and the cam 18 does not contact the brake belt 19 during the first 90-degree flipping, so as to ensure the normal flipping speed. After more than 90 degrees, the cam 18 pulls the brake belt 19. Under the action of the tension spring 20, the friction between the brake belt 19 and the cam 18 is increased to prevent damage to the reduction motor 9 caused by the instantaneous downward force when the insertion rod 11 drives the component body 5 to rotate more than 90 degrees. The mounting seat 16 can be adjusted by rotating bolts, so as to adjust the tightness of the brake belt 19, add the force required for the insertion rod 11 to rotate through friction, and decelerate the polygonal slide rod 17 when flipping more than 90 degrees.Further prevent the component body 5 from rotating more than 90 degrees with the insertion rod 11, so as to avoid damage to the reduction motor 9 caused by the falling force.

[0032] An optoelectronic induction sensor 24 is provided on the storage table 3. The optoelectronic induction sensor 24 is used to position the wooden bracket 6 when it is transported to the storage table 3 by the second conveyor device 2, so as to ensure that the component body 5 can accurately land on the wooden bracket 6 when the component body 5 is flipped from the first conveyor device 1 to the storage table 3, realizing the automatic positioning of the wooden bracket 6. In addition, the motor speed is controlled by the electric control - PLC in sub-bands to replace the traditional time relay control in the original industry. The front side is positioned by the minimum center size of the component body 5 to cover all the component bodies 5. Through this solution, all the component bodies 5 are centered in the assembly line after flipping, and the transverse conveyor line wooden bracket 6 is also automatically positioned in the center of the assembly line. After the component body 5 reaches the center of the wooden bracket 6, the induction device gives instructions to the PLC program, and issues an instruction to make the transverse conveyor line automatically sink and dock with the rear assembly line, and makes the driving roller work to transport the whole wooden bracket 6 and the components to the rear assembly line assembly station, completing the whole action instruction and entering the next cycle working program, so as to solve and improve the connection problem of the assembly line automation.

[0033] Working principle: When the component body 5 is turned and stored, the first conveying device 1 conveys the component body 5 towards the turning device, and the second conveying device 2 conveys the wooden bracket 6 onto the storage table 3. First, the rollers on the storage table 3 do not move, and the first conveying device 1 continuously conveys the component body 5. The two-way electric push rod 12 adjusts according to the position of the jack in the middle of the component body 5, so that the slider 10 drives the inserting rod 11 to move on the polygonal sliding rod 17, aligning the sliding rod with the jack. Then, the first conveying device 1 conveys the component body 5 to the right, making the inserting rod 11 enter the jack. Then, the reduction motor 9 works to drive the driving gear 21 to rotate, and through the connecting gear 22, the driven gear 23 rotates, thereby driving the polygonal sliding rod 17 to rotate, driving the inserting rod 11 to turn, and making the component body 5 rotate circumferentially along the polygonal sliding rod 17, so that the component body 5 falls onto the wooden bracket 6 on the storage table 3. By making the rollers on the storage table 3 rotate, the wooden bracket 6 and the component body 5 are driven to move towards the third conveying device 4, and the third conveying device 4 conveys the component body 5 to the next link. When the reduction motor 9 drives the polygonal sliding rod 17 to turn and the inserting rod 11 rotates more than 90 degrees, the protruding part of the cam 18 contacts the inner surface of the brake belt 19. Before turning 90 degrees, the cam 18 does not contact the brake belt 19, thus ensuring the normal turning speed. After exceeding 90 degrees, the cam 18 pulls the brake belt 19, and under the action of the tension spring 20, the friction between the brake belt 19 and the cam 18 is increased, preventing damage to the reduction motor 9 caused by the instantaneous downward force when the inserting rod 11 drives the component body 5 to rotate more than 90 degrees. The mounting seat 16 can be adjusted by turning the bolts, so that the tightness of the brake belt 19 can be adjusted. When cooperating with the first conveying device 1 of different specifications and different heights, the telescopic cylinder 14 can be driven to work, making the whole device move up and down, and it can be coordinated with the first conveying device 1 of different specifications, increasing the application range of the device. At the same time, when the device needs to be moved, the telescopic cylinder 14 can be used to lower the base 7, so that the universal wheels contact the ground, and the whole turning device can be moved through the universal wheels, making it more convenient to use.
