Description

Technical Field

[0001] This utility model relates to a clamping hand for the production and transportation of woven bags, belonging to the technical field of woven bag transportation equipment. Background Technology

[0002] Currently, in the production and logistics of woven bags (especially PP / PE woven bags used for packaging heavy items such as cement, fertilizer, feed, and grain), it is frequently necessary to grasp, handle, stack, or load single or multiple woven bags. Common handling methods include manual handling and the use of suction cups or forklift attachments. However, woven bags are relatively fragile, and improper clamping force applied by ordinary grippers or forklifts can easily cause the bag to break, resulting in tears or seams coming undone, severely affecting the integrity of the packaging and subsequent use. Suction cups, on the other hand, cannot effectively adhere to the rough surface of the woven bag. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a clamping hand for the production and transportation of woven bags. It can effectively clamp woven bags and avoid damage to the woven bags due to excessive clamping force. At the same time, it can adapt to woven bags of different sizes and shapes and is easy to operate.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a clamping hand for transporting woven bags, comprising: Mounting bracket; A clamping hand assembly, comprising a first clamping hand frame and a second clamping hand frame, both the first clamping hand frame and the second clamping hand frame being slidably mounted on the mounting bracket, and the first clamping hand frame and the second clamping hand frame being arranged opposite to each other; The first clamping frame is evenly equipped with a plurality of first clamping tubes, and the second clamping frame is evenly equipped with a plurality of second clamping tubes. A first pressure sensor is provided in the first clamping tube, and a second pressure sensor is provided in the second clamping tube. The main controller is mounted on a mounting bracket and is electrically connected to the first pressure sensor and the second pressure sensor. The first clamping arm and the second clamping arm are adapted to slide towards each other to clamp stacked woven bags. The first pressure sensor and the second pressure sensor are adapted to monitor the clamping pressure in real time. When the first clamping tube and the second clamping tube contact the stacked woven bags, the main controller dynamically adjusts the sliding displacement of the first clamping arm and the second clamping arm according to the pressure.

[0005] Furthermore, the first clamping hand is adapted to be slidably mounted on the mounting bracket via at least one first guide rail slider pair; The first guide rail slider pair includes a first guide rail mounted on the mounting bracket and a first slider mounted on the first clamping hand frame.

[0006] Furthermore, the second clamping hand is adapted to be slidably mounted on the mounting bracket via at least one second guide rail slider pair; The second guide rail slider assembly includes a second guide rail mounted on the mounting bracket and a second slider mounted on the second clamping hand frame.

[0007] Furthermore, to ensure stable clamping, the distance between two adjacent first clamping tubes is equal; The distance between any two adjacent second clamping tubes is equal; When the first clamping arm abuts against the second clamping arm, the second clamping tube is positioned between the two first clamping tubes.

[0008] Furthermore, a clamping hand for woven bag production and transportation also includes a driving assembly, which includes a first driving member and a second driving member, the fixed ends of which are both hinged to the mounting bracket. The movable end of the first driving member is hinged to the first clamping frame; The movable end of the second drive member is hinged to the second clamping frame.

[0009] Furthermore, in order to prevent excessive compression of the woven bag, a clamping hand for woven bag production and transportation also includes at least one limiting block, which is movably mounted on the mounting bracket. The side of the limiting block facing the first clamping hand frame and / or the second clamping hand frame is provided with a contact sensor, which is electrically connected to the main controller.

[0010] Furthermore, the limiting block is provided with elastic grippers, which are made of flexible rubber material, and the limiting block is adapted to be movably mounted on the mounting bracket via the elastic grippers.

[0011] Furthermore, the top of the mounting bracket is provided with a slide for connecting to external equipment.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects: In this utility model, in the initial state, the first clamping frame and the second clamping frame are in the open state. When the equipment needs to be used for clamping, the external equipment moves the entire equipment above the woven bag stack through the slide rail at the top of the mounting bracket. The first driving component and the second driving component synchronously push the corresponding first clamping frame and the second clamping frame to slide towards each other along the guide rail slider pair. When the clamping tube contacts the surface of the woven bag, the pressure sensor collects the contact pressure data in real time and transmits it to the main controller. The main controller dynamically adjusts the extension and retraction of the first and second drive components based on the difference between the preset pressure threshold and the real-time pressure value. If the pressure is lower than the threshold, the first and second drive components continue to advance, reducing the clamping distance. If the pressure exceeds the threshold, the first and second driving components will immediately retract a certain distance and stop; or the first and second clamping arms will contact the limit block and trigger the contact sensor alarm, and the first and second driving components will immediately retract a certain distance and stop. When the pressure reaches the preset safety range, the first and second clamping arms stop moving, and the staggered layout of the first and second clamping tubes completely covers the surface of the woven bag, forming a multi-point uniform force distribution. Subsequently, after the external device carries the woven bag to the target position, the first and second drive components move in opposite directions, the first and second clamping frames separate and reset, and the woven bag is released smoothly.

Detailed Implementation

[0014] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0015] like Figure 1-3 As shown, a gripper for transporting woven bags includes: Mounting bracket 1; The clamping hand assembly includes a first clamping hand frame 21 and a second clamping hand frame 22. Both the first clamping hand frame 21 and the second clamping hand frame 22 are slidably mounted on the mounting bracket 1, and the first clamping hand frame 21 and the second clamping hand frame 22 are arranged opposite to each other. A plurality of first clamping tubes 211 are evenly installed on the first clamping frame 21, and a plurality of second clamping tubes 221 are evenly installed on the second clamping frame 22. A first pressure sensor is provided in the first clamping tube 211, and a second pressure sensor is provided in the second clamping tube 221. Main controller 3 is mounted on mounting bracket 1 and is electrically connected to the first pressure sensor and the second pressure sensor. The first clamping arm 21 and the second clamping arm 22 are adapted to slide towards each other to clamp the stacked woven bags. The first pressure sensor and the second pressure sensor are adapted to monitor the clamping pressure in real time. When the first clamping tube 211 and the second clamping tube 221 contact the stacked woven bags, the main controller dynamically adjusts the sliding displacement of the first clamping arm 21 and the second clamping arm 22 according to the pressure.

[0016] Specifically, such as Figure 1-3 As shown, the first clamping arm 21 is adapted to be slidably mounted on the mounting bracket 1 via at least one first guide rail slider pair; The first guide rail slider pair includes a first guide rail 41 mounted on the mounting bracket 1 and a first slider 42 mounted on the first clamping hand frame 21.

[0017] like Figure 1-3 As shown, the second clamping arm 22 is adapted to be slidably mounted on the mounting bracket 1 via at least one second guide rail slider pair; The second guide rail slider pair includes a second guide rail 43 mounted on the mounting bracket 1 and a second slider 44 mounted on the second clamping frame 22.

[0018] like Figure 1-3 As shown, the distance between two adjacent first clamping tubes 211 is equal; The distance between two adjacent second clamping tubes 221 is equal; When the first clamping arm 21 abuts against the second clamping arm 22, the second clamping tube 221 is positioned between the two first clamping tubes 211.

[0019] like Figure 1-3 As shown, a clamping hand for woven bag production and transportation also includes a driving assembly, which includes a first driving member 51 and a second driving member 52. The fixed ends of the first driving member 51 and the second driving member 52 are both hinged to the mounting bracket 1. The movable end of the first driving member 51 is hinged to the first clamping frame 21; The movable end of the second drive member 52 is hinged to the second clamping frame 22.

[0020] In this embodiment, the first driving member 51 and the second driving member 52 can be either a cylinder or a motor.

[0021] like Figure 1-3 As shown, a clamping hand for woven bag production and transportation also includes at least one limiting block 6, which is movably mounted on the mounting bracket 1. The side of the limiting block 6 facing the first clamping hand frame 21 and / or the second clamping hand frame 22 is provided with a contact sensor, which is electrically connected to the main controller 3.

[0022] like Figure 1-3As shown, the limiting block 6 is provided with an elastic gripper, which is made of flexible rubber material. The limiting block 6 is suitable for being movably mounted on the mounting bracket 1 by means of the elastic gripper.

[0023] like Figure 1-3 As shown, the top of the mounting bracket 1 is provided with a slide 7 for connecting to external equipment.

[0024] In this embodiment, in the initial state, the first clamping frame 21 and the second clamping frame 22 are in the open state. When it is necessary to use the equipment for clamping, the external equipment moves the entire equipment above the woven bag stack through the slide 7 at the top of the mounting bracket 1. The first driving member 51 and the second driving member 52 synchronously push the corresponding first clamping frame 21 and the second clamping frame 22 to slide towards each other along the guide rail slider pair. When the clamping tube contacts the surface of the woven bag, the pressure sensor collects the contact pressure data in real time and transmits it to the main controller 3. The main controller 3 dynamically adjusts the extension and retraction of the first drive component 51 and the second drive component 52 according to the difference between the preset pressure threshold and the real-time pressure value. If the pressure is lower than the threshold, the first drive component 51 and the second drive component 52 continue to advance, reducing the clamping distance. If the pressure exceeds the threshold, the first drive unit 51 and the second drive unit 52 immediately retract a certain distance and stop, or the first clamping arm 21 and the second clamping arm 22 contact the limit block 6 and trigger the contact sensor alarm, and the first drive unit 51 and the second drive unit 52 immediately retract a certain distance and stop. When the pressure reaches the preset safety range, the first clamping frame 21 and the second clamping frame 22 stop moving, and the staggered layout of the first clamping tube 211 and the second clamping tube 221 completely covers the surface of the woven bag, forming a multi-point uniform force. Subsequently, after the external device moves the woven bag to the target position, the first drive component 51 and the second drive component 52 move in opposite directions, the first clamping arm 21 and the second clamping arm 22 separate and reset, and the woven bag is released smoothly.
