Description

Technical Field

[0001] The present application relates to the technical field of wet wipes production equipment, and in particular to a roll-changing and unloading device. Background Art

[0002] Wet wipes are a common hygiene product. Their raw materials are non-woven fabrics stored in rolls, which are processed into wet wipes.

[0003] The wet wipes production equipment is usually provided with an unwinding shaft for fixing the cloth roll (i.e. the wet wipes raw material). The unwinding shaft is rotatably connected to the frame, and rotating the unwinding shaft drives the cloth roll to rotate to achieve unwinding.

[0004] Usually, after the cloth roll is used up, the staff needs to remove the core tube of the cloth roll and then replace it with a new cloth roll. This process puts a heavy workload on the staff and the work efficiency is low. Utility Model Content

[0012] By adopting the above technical solution, the ribs are set to limit the position of the cloth roll, so that the position of the cloth roll is consistent each time it is loaded. At the same time, it is also convenient for the ribs on the gripping piece to push the cloth roll close to the unwinding shaft.

[0013] Optionally, the sum of the length of the material grabbing member and the length of the unwinding shaft is smaller than the length of the cloth roll core tube.

[0014] By adopting the above technical solution, the sum of the lengths of the grabbing piece and the unwinding shaft is less than the length of the core tube, that is, when the grabbing piece places the cloth roll on the unwinding shaft, a gap is set between the grabbing piece and the unwinding shaft, so that the two guard edges can press against the cloth roll, thereby improving the accuracy of positioning the cloth roll.

[0016] By adopting the above technical solution, in the actual production process, multiple unwinding devices are arranged at intervals along the length direction of the slide rail, and the sliding slide seat can drive the robot arm to slide in the horizontal direction, so that the robot arm can correspond to multiple production lines and load multiple unwinding devices.

[0017] Optionally, a mounting plate is provided between the slide rail and the bracket, the mounting plate is fixed on the rack, and the slide rail is fitted with the mounting plate and fixedly connected to the mounting plate.

[0018] By adopting the above technical solution, a mounting plate is provided to provide support and installation space for the slide rail, thereby facilitating the installation of the slide rail and improving the stability of the slide rail after installation.

[0022] By adopting the above technical solution, the gear is set as a helical gear, which improves the stability of the gear and rack transmission, thereby improving the sliding stability of the sliding seat, and facilitating the positioning of the robot arm.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a roll-changing and unwinding device.

[0032] Reference Figure 1 and Figure 2 A roll-changing and unloading device includes an unwinding device 1 and a robotic arm 2. The unwinding device 1 is used to place a cloth roll and unwind the cloth roll to facilitate subsequent wet wipes processing. One end of the robotic arm 2 is connected to the unwinding device 1, and the end of the robotic arm 2 away from the unwinding device 1 is provided with a grabbing member 4 for grabbing the cloth roll. The robotic arm 2 can drive the grabbing member 4 to approach or move away from the unwinding device 1. The robotic arm 2 is controlled by a PLC program and can automatically place the cloth roll on the unwinding device 1, thereby reducing the labor burden of the staff and improving the wet wipes production efficiency. At the same time, the robotic arm 2 in this embodiment is set as a six-degree-of-freedom robotic arm 2 to improve the flexibility of the robotic arm 2 in driving the cloth roll to move.

[0033] Reference Figure 1 and Figure 2The unwinding device 1 includes a frame 11 and a rotating frame 12, and the rotating frame 12 is rotatably connected to the frame 11. A plurality of unwinding shafts 13 are arranged on the rotating frame 12 around its own rotation axis, and three are arranged in this embodiment. The unwinding shaft 13 is rotatably connected to the frame 11 around its own circumference, and the cloth roll can be sleeved on the unwinding shaft 13. In this embodiment, the unwinding shaft 13 is an air-expanding shaft, and the cloth roll is supported and fixed by the expansion and contraction of the air-expanding shaft. The rotation of the unwinding shaft 13 can drive the cloth roll to rotate, thereby realizing the unwinding of the cloth roll.

[0034] Reference Figure 1 and Figure 3 In this embodiment, the material grabbing piece 4 is also an inflatable shaft, and the length of the cloth roll core is defined as d0, the length of the material grabbing piece 4 is d1, and the length of the unwinding shaft 13 is d2; then d1+d2 is less than or equal to d0. An annular rib is sleeved on the inflatable shaft, and the sum of the lengths of the two inflatable shafts is set to be less than the length of the core tube, so that the core tube can abut against the rib after being sleeved on the inflatable shaft, so that the position of the cloth roll is consistent during multiple feeding processes. In this embodiment, and d1+d2 is less than d0, it is convenient for a rib on the material grabbing piece 4 to push the cloth roll to approach the unwinding shaft 13. The cloth roll is positioned by the rib on the unwinding shaft 13 to ensure that the cloth roll is in a consistent position on the equipment each time, thereby ensuring that the product position is consistent after the cloth is connected.

In the actual production process, multiple unwinding devices 1 can be arranged along the length direction of the slide rail 51, and the robot arm can replace the cloth rolls of multiple unwinding devices 1 by sliding the slide seat 52. A mounting plate 53 is provided between the slide rail 51 and the bracket. The slide rail 51 is fitted with the mounting plate 53 and fixedly connected to the mounting plate 53 by screws to facilitate the fixed installation of the slide rail 51. In order to improve the stability of the slide seat 52 during the sliding process, multiple slide rails 51 can be arranged at intervals in a direction perpendicular to its own length. In this embodiment, two are provided.

In this embodiment, the driving member 33 is a servo motor, and the housing of the servo motor is fixedly connected to the sliding seat 52 by screws. The output shaft of the servo motor is fixedly connected to the gear 31. The rotation of the output shaft of the servo motor can drive the gear 31 to rotate, thereby causing the gear 31 to roll on the rack 32 and drive the sliding seat 52 to move, thereby driving the sliding seat 52.
