Description

Technical Field

[0001] This utility model relates to the field of automated conveying technology, and specifically to a rotary lifting device for a conveyor line. Background Technology

[0002] Currently, double-speed conveyor lines are frequently used in automated production lines to transport materials, and sometimes it is necessary to rotate the materials on the conveyor line at a certain angle.

[0003] Traditional lifting and rotating devices are generally installed inside the conveyor line. For example, Chinese patent application No. 202323513062.6 proposes a conveyor line rotating and lifting device. In use, the lifting machine lifts the items on the cross-shaped rotating bracket, and then the rotating motor rotates the items on the platform to change the angle of the items. However, when using this cross-shaped rotating bracket, the rotation angle can only be an integer multiple of 90°. Moreover, during the lifting and lowering process, due to the influence of the upper roller of the upper plate, it is necessary to ensure that the rotation angle is not deviated, otherwise it will affect the lifting and lowering of the rotating bracket. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a rotary lifting device for conveyor lines, thereby resolving the problems mentioned in the background section regarding the limited rotation angle of items on conveyor lines and the impact on lifting caused by deviations in rotation angle.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a rotary lifting device for a conveyor line, comprising a support frame, a power conveying roller, an outer lifting sleeve, and an inner lifting rotary cylinder. The inner lifting rotary cylinder is provided with a mounting plate, the power conveying roller is mounted on the mounting plate, and a support column is provided at the bottom of the mounting plate. The support column passes through the inner lifting rotary cylinder and is mounted inside the support frame. The inner lifting rotary cylinder is rotatably mounted inside the outer lifting sleeve. The support frame is provided with a drive mechanism for driving the outer lifting sleeve to rise and fall. When the drive mechanism is not activated, the bottom of the outer lifting sleeve is in contact with the support frame.

[0006] Furthermore, the inner lifting rotating cylinder includes a first inner sleeve and a second inner sleeve, which are integrally designed. The inner diameter of the first inner sleeve is larger than that of the second inner sleeve. A toothed ring is provided on the outer circumference of the second inner sleeve, and a drive gear is meshed on one side of the toothed ring. A drive motor is installed at the bottom of the outer lifting sleeve, and the output shaft of the drive motor is connected to the drive gear.

[0007] Furthermore, the drive mechanism includes support plates arranged around the outer lifting sleeve, and cylinders are installed on both sides of the support frame, with the output ends of the cylinders connected to the corresponding support plates.

[0008] Furthermore, a guide rod is fixed on the support frame and located between the two cylinders, with one end of the guide rod slidably mounted on the corresponding support plate.

[0009] Furthermore, non-powered conveying rollers are provided on both sides of the mounting plate located on the powered conveying roller.

[0010] Furthermore, a support ring extends outward from the top of the inner lifting rotating cylinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model controls the outer lifting sleeve and the inner lifting rotating cylinder to lift the item, and then through the cooperation of the drive motor, gear ring, and gear, the item located at the top of the inner lifting rotating cylinder is rotated at a certain angle to achieve the purpose of changing the direction of the item on the conveyor line; by setting the outer lifting sleeve and the inner lifting rotating cylinder outside the power conveying roller, it is ensured that the lifting process is not limited by the roller after rotating at any angle, thus improving the diversity of the rotation angle of the item.

Detailed Implementation

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-3As shown, this utility model provides a rotary lifting device for a conveyor line, including a support frame 1, a power conveying roller 2, an outer lifting sleeve 3, and an inner lifting rotary cylinder 4. The inner lifting rotary cylinder 4 is provided with a mounting plate 5, the power conveying roller 2 is mounted on the mounting plate 5, and a support column 6 is provided at the bottom of the mounting plate 5. The support column 6 passes through the inner lifting rotary cylinder 4 and is located inside the support frame 1. The inner lifting rotary cylinder 4 is rotatably mounted inside the outer lifting sleeve 3, and the top of the inner lifting rotary cylinder 4 protrudes from the outer lifting sleeve 3 to facilitate contact between the inner lifting rotary cylinder 4 and the object. The support frame 1 is provided with a drive mechanism 7 for driving the outer lifting sleeve 3 to lift and lower. When the drive mechanism 7 is not activated, the bottom of the outer lifting sleeve 3 is in contact with the support frame 1 to support the outer lifting sleeve 3 and the inner lifting rotary cylinder 4.

[0018] like Figure 1 As shown, in use, the rotary lifting device is placed between two conveyor lines. The height of the power conveyor roller 2 is the same as the height between the two conveyor lines on both sides. When it is not necessary to turn the item and only the item needs to be transported, the heights of the outer lifting sleeve 3 and the inner lifting rotating cylinder 4 are both lower than the height of the power conveyor roller 2. When it is necessary to turn the item, after the item is transported from one conveyor line to the power conveyor roller 2, the operation of the power conveyor roller 2 is stopped. At the same time, the drive mechanism 7 drives the outer lifting sleeve 3 to drive the inner lifting rotating cylinder 4 to rise. The inner lifting rotating cylinder 4 lifts the item on the power conveyor roller 2 and then rotates it to a certain angle. Finally, the drive mechanism 7 drives the outer lifting sleeve 3 to drive the item on the inner lifting rotating cylinder 4 to fall down, so that the item falls onto the power conveyor roller 2. The power conveyor roller 2 starts and transports the rotated item to another conveyor line. This operation is repeated. By setting the power conveyor roller 2 inside the inner lifting rotating cylinder 4, it is possible to turn the item at any angle. At the same time, it is ensured that after rotating at any angle, the lifting process is not limited by the roller, which improves the diversity of the item's rotation angle.

[0019] The inner lifting rotating cylinder 4 includes a first inner sleeve 41 and a second inner sleeve 42. The first inner sleeve 41 and the second inner sleeve 42 are designed as a single piece, and the inner diameter of the first inner sleeve 41 is larger than the inner diameter of the second inner sleeve 42. A toothed ring 8 is fixed on the outer periphery of the second inner sleeve 42. A drive gear 9 is meshed on one side of the toothed ring 8. A drive motor 10 is installed at the bottom of the outer lifting sleeve 3, and the output shaft of the drive motor 10 is connected to the drive gear 9.

[0020] like Figure 2 and 3As shown, the first inner sleeve 41 is located above the second inner sleeve 42. The first inner sleeve 41 is rotatably installed inside the outer lifting sleeve 3. The mounting plate 5 and the power conveying roller 2 are both inside the first inner sleeve 41, and the mounting plate 5 has a certain gap with the bottom of the first inner sleeve 41. In this embodiment, the drive motor drives the active gear 9 to rotate, thereby driving the first inner sleeve 41, which is integrated with the second inner sleeve 42, to rotate, thereby driving the item on the top of the first inner sleeve 41 to rotate, achieving the purpose of automatic rotation of the item.

[0021] The drive mechanism 7 includes a support plate 71 arranged around the outer lifting sleeve 3, and cylinders 72 are installed on both sides of the support frame 1. The output end of the cylinder 72 is connected to the corresponding support plate 71.

[0022] like Figure 2 As shown, the cylinder 72, under the action of the support plate 71, drives the outer lifting sleeve 3 and the inner lifting rotating cylinder 4 to rise and fall, thereby achieving the purpose of lifting and lowering the items.

[0023] A guide rod 73 is fixed on the support frame 1 and located between the two cylinders 71. One end of the guide rod 73 is slidably mounted on the corresponding support plate 71.

[0024] like Figure 1 As shown, the guide rod 73 serves to guide the outer lifting sleeve 3 to move up and down, ensuring that it maintains the correct direction during the lifting process.

[0025] Non-powered conveying rollers 11 are provided on the mounting plate 5 and on both sides of the powered conveying roller 2.

[0026] like Figure 2 As shown, since both the outer lifting sleeve 3 and the inner lifting rotating cylinder 4 are circular structures, their shapes cause the length of the power conveying roller 2 to not be consistent. Therefore, a non-power conveying roller 11 is installed on both sides of the power conveying roller 2 to prevent the distance between the conveying rollers from being too wide and affecting the conveying of items.

[0027] The top of the inner lifting rotating cylinder 4 has a support ring 43 extending outward.

[0028] like Figure 1 and 3 As shown, the support ring 43 can be used to increase the contact area between the item and the top of the inner lifting rotating cylinder 4, thereby improving the stability during rotation and lifting.

[0029] Operating principle: When it is necessary to turn the item, when the item moves onto the power conveyor roller 2, the operation of the power conveyor roller 2 is stopped, and then the cylinder 72 is started to drive the outer lifting sleeve 3 and the inner lifting rotating cylinder 4 to rise, lifting the item on the power conveyor roller 2 so that the item is detached from the power conveyor roller 2. Then, the drive motor 10 is started to control the drive gear 9 to drive the inner lifting rotating cylinder 4 connected to the gear ring 8 to rotate, causing the item on the inner lifting rotating cylinder 4 to rotate to the required angle. After the required angle is reached, the cylinder 72 retracts, causing the item on the inner lifting rotating cylinder 4 to fall onto the power conveyor roller 2. Finally, the power conveyor roller 2 is started again to continue transporting the rotated item.

[0030] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
