Automatic diaper grabbing device

Abstract

This invention relates to the field of diaper manufacturing equipment technology, specifically an automatic diaper gripping device. It includes a connecting base connected to other components and a gripping module for gripping diapers. The gripping module includes a mounting frame, rollers, a servo motor, a belt, and gripping blocks. The mounting frame is fixed to the connecting base. Rollers are respectively disposed at both ends of the mounting frame, forming a rotating pair with the mounting frame. The servo motor is mounted on the mounting frame, and its shaft is connected to one of the rollers. The belt is fitted onto the rollers and can be driven by them. The gripping blocks are disposed on the outside of the belt, with different heights.

By using gripping blocks of different heights to complete the gripping action, the device accurately grips the diaper surface while preventing punctures and wrinkles.

Description

Technical Field

[0001] This invention relates to the field of diaper production and processing equipment, and in particular to an automatic diaper gripping device. Background Technology

[0002] Disposable diapers (also known as diapers) are disposable absorbent hygiene products. Their core function is to quickly absorb and lock in urine, keeping the skin dry. They are mainly used by infants and incontinent adults to keep the user's genitals dry.

[0003] Diaper gripping equipment is a core device in automated production lines, mainly used for the automated transfer of diaper products during production, packaging, and stacking. Currently, mainstream technologies can be categorized into three types: suction gripping, clamping gripping, and robotic transfer. Suction gripping requires high negative pressure control; otherwise, the diaper film and non-woven fabric are easily torn under air pressure, and the structure is relatively complex. Clamping gripping, on the other hand, uses a robotic arm to adhere tightly to the diaper surface, which can easily lead to contamination and damage. The purpose of this invention is to propose a new diaper gripping device to solve the problems existing in the prior art. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic diaper gripping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a connecting base connected to other components and a gripping module for gripping diapers. The gripping module includes a mounting frame, rollers, a servo motor, a belt, and gripping blocks. The mounting frame is fixed to the connecting base. The rollers are respectively disposed at both ends of the mounting frame, forming a rotating pair with the mounting frame. The servo motor is disposed on the mounting frame, and the servo motor shaft is connected to one of the rollers. The belt is sleeved on the rollers and can be driven by the rollers. The gripping blocks are disposed on the outside of the belt, and different gripping blocks have different heights.

[0006] To optimize the above technical solution, the following measures are further taken: the gripping module is at least two, and they are set in pairs to ensure that the diaper is evenly clamped from both sides.

[0007] As a further improvement to the above technical solution: the rollers are respectively arranged at both ends of the mounting frame and distributed along the length of the mounting frame.

[0008] As a further improvement to the technical solution: the gripping blocks are evenly distributed on the outside of the belt, and the height of the gripping blocks gradually increases in an arithmetic sequence.

[0009] As an improvement to the aforementioned technical solution, the servo motors of adjacent gripping modules rotate in opposite directions.

[0010] Furthermore: The gripping block has a frosted surface and is made of elastic plastic. Its purpose is to improve the surface engagement between the gripping block and the diaper surface, and to prevent the gripping block from separating from the diaper during the gripping process. The elastic plastic is existing technology and is known to those skilled in the art. Therefore, its specific material and parameters will not be further explained. Technicians can choose different elastic plastics to manufacture the gripping block according to production needs, cost and other factors, which will not have a substantial impact on the technical effect.

[0011] As can be seen from the above description of the structure of the present invention, compared with the prior art, the present invention has the following advantages: During the grasping process, the robotic arm does not need to be in close contact with the surface of the diaper, which can avoid contamination and damage to the diaper surface; The gripping action is completed by gripping blocks of different heights, which can accurately grasp the surface of the diaper while avoiding punctures and wrinkles. Attached Figure Description

The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings: Figure 1 This is a schematic diagram of the three-dimensional structure of the present invention; Figure 2 This is a schematic diagram of the disassembled structure of the present invention; In the diagram: Connector-100, Gripping Module-200, Mounting Bracket-201, Roller-202, Servo Motor-203, Belt-204, Gripping Block-205 Detailed Implementation

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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. Example

[0014] Please see Figure 1 and Figure 2 The present invention provides an automatic diaper gripping device, including a connecting base 100 connected to a robotic arm and two gripping modules 200 for gripping diapers. Each gripping module 200 includes a mounting frame 201, a roller 202, a servo motor 203, a belt 204, and a gripping block 205.

[0015] The mounting frame 201 is fixed to the connecting seat 100, and the rollers 202 are respectively arranged at both ends of the mounting frame 201 and distributed along the length of the mounting frame 201. The rollers 202 and the mounting frame 201 form a rotating pair. The servo motor 203 is mounted on the mounting bracket 201. The shaft of the servo motor 203 is connected to a roller 202. The servo motor 203 shafts of adjacent gripping modules 200 rotate in opposite directions. The belt 204 is fitted on the roller 202 and can be driven by the roller 202; The gripping blocks 205 are disposed on the outside of the belt 204. The gripping blocks 205 have different heights and are evenly distributed on the outside of the belt 204. The height of the gripping blocks 205 gradually increases in an arithmetic sequence. The surface of the gripping blocks 205 is frosted and the gripping blocks 205 are made of elastic plastic material.

[0016] Working principle: The servo motor 203 drives the roller 202, which in turn drives the gripping blocks 205 at different heights on the belt 204 to grip the diaper. This eliminates the need for the robotic arm to be in close contact with the diaper surface, thus avoiding the technical problems of contaminating and damaging the diaper surface due to the robotic arm being too close to the diaper surface during the gripping process.

[0017] Since the servo motors 203 of adjacent gripping modules 200 rotate in opposite directions, the gripping blocks 205 located in different gripping modules 200 can cooperate to grip the surface of the diaper. Since the gripping blocks 205 set on the belt 204 are of different heights, it can be ensured that the gripping blocks 205 accurately clamp the surface of the diaper, thus avoiding the surface of the diaper being punctured or wrinkled.

[0018] The control method of this invention is to achieve automatic control through an external controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.
