Description

Technical Field

[0001] The utility model relates to the field of disposable sanitary product equipment, in particular to a transfer and steering device. Background Art

[0002] At present, in the production process of disposable sanitary products, an important step is to grab the products from the production line, turn them, and then input them into the production line again. For example, the device for changing the spacing between the conveyed products and rotating these products disclosed in Chinese Patent Publication No. CN101583549B discloses a technical solution for realizing variable speed conveying of products during the conveying process using multiple motors.

[0003] In addition, the applicant disclosed a diaper waist multi-motor controlled high-speed flipping and pulling device in Chinese patent announcement number CN221369684U, including a frame, a rotating shaft rotatably arranged on the frame, a track wheel arranged on the rotating shaft, a plurality of swing arms rotatably arranged on the frame, a plurality of swing arms rotatably arranged on the swing arms, a suction cup and a plurality of variable speed servo motors, each variable speed servo motor is connected to each swing arm by transmission, a rotating track is arranged on the track wheel, a rotating arm is arranged at the lower end of the suction cup, a roller assembly is arranged on the rotating arm, the roller assembly is placed in the rotating track, a constant speed servo motor is arranged on the frame, the constant speed servo motor is connected to the rotating shaft by transmission, a planetary reducer is arranged on the output end of each variable speed servo motor, and the rotating shaft is connected to each planetary reducer by transmission. The product is adsorbed by the suction cup, and the rotation of the suction cup is controlled by the track wheel structure, that is, when the suction cup is located at different circumferential positions of the rotating shaft, the rotation angle of the suction cup is fixed. The existing disposable sanitary products field usually adopts this method to realize the self-rotation of the product itself.

[0004] Although the self-rotation method using a cam structure or similar structure is simple in structure and has a good control effect, it still has its limitations, that is, the self-rotation of the bearing mechanism used to receive the object cannot be effectively controlled. Especially after the suction cup can achieve speed change around the rotation axis, in order to cooperate with this speed change, the speed change of the suction cup's self-rotation also becomes the key. Utility Model Content

[0005] Therefore, in view of the above-mentioned problems, the present invention proposes a transfer and steering device, which solves the technical problem that the existing carrying mechanism for receiving articles cannot achieve effective control.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A indexing and steering device, comprising a main shaft, two or more conveying mechanisms rotatable around the main shaft, and two or more first driving mechanisms for driving the conveying mechanisms to rotate around the main shaft. The conveying mechanism includes a supporting mechanism rotatable around the main shaft, a loading mechanism for carrying articles, and a second driving mechanism provided on the supporting mechanism. The loading mechanism is rotatably provided on the second driving mechanism or the supporting mechanism, and the loading mechanism is controlled by the second driving mechanism to rotate independently and is not controlled by the rotation of the first driving mechanism and / or the main shaft.

[0007] Further, the second driving mechanism is a rotating platform, and the loading mechanism realizes controlled rotation on the rotating platform.

[0008] Further, the second driving mechanism is a servo motor provided on the supporting mechanism, and the loading mechanism is rotatably provided on the supporting mechanism to realize controlled rotation.

[0009] Further, it further includes a constant-speed motor, which is in transmission connection with the main shaft. The first driving mechanism includes a servo motor and a planetary reducer provided on the output shaft of the servo motor. The planetary reducer has an output shaft and a planet carrier. The conveying mechanism is in transmission connection with the output shaft to rotate around the main shaft. A plurality of transmission wheels are provided on the main shaft, and each transmission wheel is in transmission connection with each planet carrier respectively. When the constant-speed motor rotates, the conveying mechanism is controlled by the constant-speed motor, or when the first driving mechanism rotates, the conveying mechanism is controlled by the first driving mechanism, or when the constant-speed motor and the first driving mechanism rotate, the conveying mechanism is controlled by the first driving mechanism and the constant-speed motor.

[0010] Further, the supporting mechanism includes a first bracket rotatably provided on the main shaft, a second bracket rotatably provided on the main shaft, and a supporting cross frame. The supporting cross frame is horizontally arranged across the upper ends of the first bracket and the second bracket. The second bracket is in transmission connection with the first driving mechanism.

[0011] Further, a pneumatic connection structure for providing negative pressure to the loading mechanism is provided on the supporting cross frame or the second driving mechanism.

[0012] Further, a rotary slip ring is provided on the main shaft, and each second driving mechanism realizes electrical connection by connecting to the rotary slip ring.

[0013] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are:

[0014] 1. This solution changes the original way of using a cam mechanism to rotate the loading mechanism. Instead, an independent second driving mechanism is used to achieve the rotation of the loading mechanism, and the loading structure can be independent of the rotation of the first driving mechanism and / or the main shaft, thus enabling variable speed and orientation at any angle. This method will increase the weight and inertia of the conveying mechanism, resulting in interference in the rotation of the conveying mechanism around the main shaft. However, due to the enhanced control performance of the loading mechanism, it can break and separate two adjacent products alone or in cooperation with the first driving mechanism; it can achieve orientation at any angle at any position, thereby enabling the application of functions such as detection, processing, and marking at this station. Additionally, since the contact with the cam mechanism is reduced, that is, the friction is decreased, a better noise reduction function can be achieved.

[0015] 2. With the setting of the rotating platform, its integration performance is good, which can effectively control the weight and achieve the smoothness of conveying. When using a servo motor, relevant transmission components such as a gear set need to be equipped. Both methods can achieve the independent rotation of the loading mechanism.

[0016] 3. The setting of the constant-speed motor can be used to cooperate with the first driving mechanism to control the conveying mechanism, avoiding problems such as increased weight and inertia caused by the increased weight of the loading mechanism. At this time, each conveying mechanism is no longer in a completely independent operating state, but belongs to a controllable variable-speed state. The constant-speed motor can be used for control to achieve states such as the first driving mechanism driving alone, the constant-speed motor driving alone, and the first driving mechanism and the constant-speed motor driving in cooperation. Among them, the planetary reducer plays a crucial role, enabling various cooperation states between the first driving mechanism and the constant-speed motor, thus achieving the unity of individual controllability and overall controllability of the conveying mechanism.

[0017] 4. The setting of the support mechanism is not much different from the existing support mechanism. The main difference is that there is no support from the cam mechanism, and due to the increased weight, the strength of the support mechanism needs to be increased, which can be improved by adding rib plates, adding stiffeners, changing the material properties, etc.

[0018] 5. The pneumatic connection structure can be set at the rotating platform or on the support cross-frame of the loading mechanism to enable the access of external pipelines. Moreover, when the conveying mechanism rotates around the main shaft, these pipelines can also rotate accordingly, such as the commonly used air distribution disk structure in the existing technology.

[0019] 6. With the setting of the rotary slip ring, and grooves or holes for accommodating cables can be set on the main shaft, so that the cables of the second driving mechanism are connected to the rotary slip ring through the grooves or holes, thereby achieving electrical connection with the external power supply and ensuring the stability of the electrical supply of the second driving mechanism.

[0024] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 In this embodiment, a indexing and steering device is provided, which includes a main shaft 1, two or more conveying mechanisms 2 that rotate around the main shaft 1, and two or more first driving mechanisms 3 that drive the conveying mechanisms 2 to rotate around the main shaft 1. The conveying mechanism 2 includes a support mechanism 21 that rotates around the main shaft 1, a loading mechanism 22 for carrying articles, and a second driving mechanism 23 provided on the support mechanism 21. The loading mechanism 22 is rotatably provided on the second driving mechanism 23 or the support mechanism 21, and the loading mechanism 22 is controlled by the second driving mechanism 23 to rotate independently and is not controlled by the rotation of the first driving mechanism 3 and / or the main shaft 1.

[0026] The second driving mechanism 23 is a rotary platform, and the loading mechanism 22 realizes controlled rotation on the rotary platform. The rotary platform is a common combined component in the art, which can be purchased on the market. It is a special rotary device with a hollow structure, high load capacity, high rotation accuracy and wide adaptability, and is used to provide the power for the rotation of the loading mechanism 22. Of course, although the rotary platform is a preferred choice, it can also be replaced by other mechanisms. For example, the second driving mechanism 23 can also be a servo motor 31 provided on the support mechanism 21, and the loading mechanism 22 is rotatably provided on the support mechanism 21 to realize controlled rotation.

[0027] It also includes a constant speed motor 4, which is connected to the main shaft 1 by transmission. The first driving mechanism 3 includes a servo motor 31 and a planetary reducer 32 arranged on the output shaft 321 of the servo motor 31. The planetary reducer 32 has an output shaft 321 and a planetary carrier 322. The conveying mechanism 2 is connected to the output shaft 321 by transmission to realize rotation around the main shaft 1. A plurality of transmission wheels 11 are arranged on the main shaft 1, and each transmission wheel 11 is connected to each planetary carrier 322 by transmission. When the constant speed motor 4 rotates, the conveying mechanism 2 is controlled by the constant speed motor 4, or when the first driving mechanism 3 rotates, the conveying mechanism 2 is controlled by the first driving mechanism 3, or when the constant speed motor 4 and the first driving mechanism 3 rotate, the conveying mechanism 2 is controlled by the first driving mechanism 3 and the constant speed motor 4.

[0028] The constant speed motor 4 and the first driving mechanism 3 can both be ordinary motors, preferably a servo motor 31. The planetary reducer 32 is a conventional planetary reducer 32, and the planetary carrier 322 has an outer gear ring, so as to achieve a transmission with the transmission wheel 11.

[0029] The support mechanism 21 includes a first bracket 211 rotatably arranged on the main shaft 1, a second bracket 212 rotatably arranged on the main shaft 1, and a support cross frame 213, wherein the support cross frame 213 is arranged across the upper ends of the first bracket 211 and the second bracket 212, and the second bracket 212 is transmission-connected to the first driving mechanism 3. The support cross frame 213 or the second driving mechanism 23 is provided with a pneumatic connection structure 24 for providing negative pressure to the bearing mechanism 22.

[0030] The pneumatic connection structure 24 is an annular cavity, which is used to form a connection with the hollow chamber of the bearing mechanism 22 and form a seal. This structure is a conventional structure in the art. When realizing transmission, the first bracket or the second bracket can be rotated around the main axis, or around other rotating parts concentric with the main axis to achieve rotation stability. This structure has been disclosed in the prior art, such as a speed change device disclosed in Chinese patent application number: CN202120565679.4 or a new type of high-speed electronic speed change device disclosed in CN202310157315.6.

[0031] The main shaft 1 is provided with a rotating slip ring 12 , and each second driving mechanism 23 is electrically connected by connecting to the rotating slip ring 12 .

[0032] The rotating slip ring 12 is a conventional component in the art, which mainly provides electrical connection for rotating components.

[0033] The main change of the above structure is that the original cam structure is removed and the second driving mechanism is used to drive the movement of the bearing mechanism, and the settings of the rotating slip ring and the constant speed motor are changed accordingly.

[0034] The beneficial effects of the present utility model are as follows:

[0035] 1. In this solution, the original method of using a cam mechanism to rotate the loading mechanism is changed. Instead, an independent second driving mechanism is used to rotate the loading mechanism, and the loading structure can be independent of the rotation of the first driving mechanism and / or the main shaft, thereby achieving variable speed and orientation at any angle. This method will increase the weight and inertia of the conveying mechanism, which will cause interference to the rotation of the conveying mechanism around the main shaft. However, due to the enhanced control performance of the loading mechanism, it can break and separate adjacent two products alone or in cooperation with the first driving mechanism; it can achieve orientation at any angle at any position, thereby realizing the application of functions such as detection, processing, and marking at this station. In addition, since the contact using the cam mechanism is reduced, that is, the friction is reduced, a better noise reduction function can be achieved.

[0036] 2. With the setting of the rotating platform, its integration performance is better, which can effectively control the weight and achieve the smoothness of conveying. When using a servo motor, relevant transmission components such as a gear set need to be equipped. Both methods can achieve the independent rotation of the loading mechanism.

[0037] 3. The setting of the constant-speed motor can be used to cooperate with the first driving mechanism to control the conveying mechanism, avoiding the problems of increased weight and inertia caused by the increased weight of the loading mechanism. At this time, each conveying mechanism is no longer in a completely independent operating state, but belongs to a controllable variable-speed state. The constant-speed motor can be used for cooperation and control to achieve states such as the first driving mechanism driving alone, the constant-speed motor driving alone, and the first driving mechanism cooperating with the constant-speed motor to drive. Among them, the planetary reducer plays a key role, which realizes the possibility of various cooperation states between the first driving mechanism and the constant-speed motor, thus achieving the unity of the individual controllability and overall controllability of the conveying mechanism.

[0038] 4. The setting of the support mechanism is not much different from the existing support mechanism. The main difference is that without the support of the cam mechanism and due to the increased weight, the strength of the support mechanism needs to be increased, which can be improved by adding rib plates, adding stiffeners, changing the material properties, etc.

[0039] 5. The pneumatic connection structure can be set at the rotating platform or on the support cross frame of the loading mechanism to realize the access of external pipelines. Moreover, when the conveying mechanism rotates around the main shaft, these pipelines can also rotate accordingly, such as the commonly used air distribution disc structure in the prior art.

[0040] 6. The rotation slip ring is provided, and grooves or holes for accommodating cables can be provided on the main shaft, so that the cables of the second driving mechanism are connected to the rotation slip ring through the grooves or holes, thereby realizing the electrical connection with the external power supply and ensuring the stability of the power supply of the second driving mechanism.

[0041] Although the present utility model is specifically shown and introduced in combination with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present utility model in terms of form and details without departing from the spirit and scope of the present utility model defined by the appended claims, and all are within the protection scope of the present utility model.
