A handle lifting and conveying device

Abstract

This utility model discloses a handle lifting and conveying device, including a servo motor and a linear motor. A rotating plate is fixed to the top output shaft of the servo motor. Several limiting devices are equidistantly arranged on the top of the rotating plate. Each limiting device includes at least two limiting rods vertically fixed to the top of the rotating plate. A rotating cylinder is fixed to the drive end of the linear motor, and a lifting plate pointing towards the limiting devices is fixed to the rotating end of the rotating cylinder. Compared to existing technologies, the limiting devices of this utility model allow handles to be positioned around the device, ensuring neat stacking. The linear motor drives the handles upward via the lifting plate, and the distance the linear motor moves the lifting plate upward each time is equal to the height of the handle. Therefore, handles located around the limiting devices can be sequentially lifted to the desired gripping height, achieving automatic handle lifting.

Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, and in particular to a handle lifting and conveying device. Background Technology

[0002] Woven bags, as high-strength and wear-resistant packaging containers, are widely used in the transportation of bulk goods in fields such as grain, chemicals, and building materials. They are typically made of polypropylene or polyethylene flat yarns, and handles are attached to the sides or top of the bag to improve handling convenience. In large-scale production, woven bag handles are mostly plastic injection molded parts or flat yarn sewn parts, which need to be accurately conveyed to designated workstations by automated equipment to complete welding or sewing processes with the bag body. Therefore, the conveying efficiency and positioning accuracy of the handles directly determine the production quality and capacity of the woven bags.

[0003] In traditional production, handle conveying relies on manual labor to disassemble bundles of handles and place them one by one onto the conveyor track. This not only requires frequent adjustments to the handle posture to adapt to subsequent processes, but also results in short feeding intervals and high labor intensity due to the limited stacking height (usually no more than 30cm) of manual labor. Traditional mechanical conveying devices (such as chain conveyors) are prone to uneven stacking of handles during the conveying process, causing the gripping equipment to be unable to grasp the handles, thus affecting production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide a handle lifting and conveying device. The limiting device allows the handle to be placed on its periphery to ensure that the handles are stacked neatly. The linear motor can drive the handle to move upward through the lifting plate. The distance that the linear motor drives the lifting plate to move upward each time is equal to the height of the handle. Therefore, the handles located on the periphery of the limiting device can be lifted to the height to be grasped in sequence to realize the automatic lifting operation of the handle.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A handle lifting and conveying device includes a servo motor and a linear motor. A rotating plate is fixed to the top output shaft of the servo motor. Several limiting devices are set at equal angles on the top of the rotating plate. Each limiting device includes at least two limiting rods that are vertically fixed to the top of the rotating plate. A rotating cylinder is fixed to the drive end of the linear motor. A lifting plate pointing towards the limiting devices is fixed to the rotating end of the rotating cylinder.

[0007] Furthermore, it also includes a pad block, the top surface of which has several through holes, and the pad block is fitted onto the limiting rod through the through holes.

[0008] Furthermore, it also includes a base plate, on which both the servo motor and the linear motor are fixed.

[0009] Furthermore, a number of support rods are fixed to the top of the base plate, and the top of the support rods is provided with a support device for supporting the rotating plate.

[0010] Furthermore, the support device includes an annular track fixed to the top of the support rod, and a plurality of sliders are slidably connected on the annular track, with the plurality of sliders being fixedly connected to the rotating plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The limiting device of this utility model allows the gloves to be placed on its periphery to ensure that the handles are stacked neatly. The linear motor can drive the handles to move upward through the lifting plate, and the distance that the linear motor drives the lifting plate to move upward each time is equal to the height of the handle. Therefore, the handles located on the periphery of the limiting device can be lifted to the desired gripping height in sequence to realize the automatic lifting operation of the handles.

[0013] The handle of this utility model, which is sleeved around the limit rod, is located on the top of the pad, so that there is space between the handle and the rotating plate. Therefore, when the rotating cylinder drives the lifting plate to rotate below the handle, it will not contact the handle, ensuring that the lifting plate rotates into place and can be located below the handle.

[0014] The servo motor of this invention can drive the rotating plate to rotate at a certain angle, thereby rotating the corresponding position limiting device to one side of the lifting plate, so that the lifting plate can drive the handle on the limiting device to lift. Since there are multiple limiting devices, it is possible to feed material while loading.

[0015] The rotating cylinder of this invention can drive the lifting plate to rotate, so that the lifting plate is no longer located above the rotating plate, thereby avoiding the jamming phenomenon caused by the lifting plate coming into contact with the limiting device and its sleeved handle.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-3 As shown, a handle lifting and conveying device includes a servo motor 3 and a linear motor 1. A rotating plate 5 is fixed to the top output shaft of the servo motor 3. Several limiting devices are set at equal angles on the top of the rotating plate 5. The limiting devices include at least two limiting rods 6 that are vertically fixed to the top of the rotating plate 5. A rotating cylinder 2 is fixed to the drive end 101 of the linear motor 1. A lifting plate 10 pointing to the limiting devices is fixed to the rotating end of the rotating cylinder 2.

[0022] In this embodiment, such as Figure 1 As shown, the distance between the two limiting rods 6 of the same limiting device is equal to the length of the through groove inside the handle. When the handle is placed outside the two limiting rods 6, the two limiting rods 6 can limit the handle. Therefore, several handles stacked vertically can be fitted onto the limiting device. Then, rotating the cylinder 2 can drive the lifting plate 10 to rotate, so that the lifting plate 10 rotates to below the bottom handle (the thickness of the lifting plate 10 is 1 to 2 mm, and it can be inserted between the handle and the rotating plate 5 when rotating). At this time, when the linear motor 1 drives the lifting plate 10 to move upward, the lifting plate 10 will drive the handle to move upward, thereby raising the handle. Then, after the handle gripping device grips the top handle, the handle below can immediately rise to the handle gripping height to realize the automatic lifting operation of the handle.

[0023] The servo motor 3 can drive the rotating plate 5 to rotate at a certain angle, thereby rotating the corresponding position limiting device to one side of the lifting plate 10. This allows the lifting plate 10 to lift the handle on the limiting device. Furthermore, during the rotation of the rotating plate 5, the rotary cylinder 2 can drive the lifting plate 10 to rotate, so that the lifting plate 10 is no longer above the rotating plate 5, thus avoiding interference between the lifting plate 10 and the limiting device and its attached handle.

[0024] The system also includes a pad 7, which has several through holes 701 on its top surface. The pad 7 is fitted onto the limiting rod 6 through the through holes 701. After being fitted onto the limiting rod 6, the pad 7 will fall onto the top of the rotating plate 5. At this time, the handle fitted around the limiting rod 6 will be located on the top of the pad 7, thus creating a space between the handle and the rotating plate 5. When the rotating cylinder 2 drives the lifting plate 10 to rotate below the handle, it will not contact the handle, ensuring that the lifting plate 10 rotates into place. This allows the lifting plate 10 to lift the handle under the drive of the linear motor 1.

[0025] Among them, such as Figure 1 and Figure 2As shown, it also includes a base plate 9, with a servo motor 3 and a linear motor 1 fixed to the top of the base plate 9. Several support rods 8 are also fixed to the top of the base plate 9. Support devices 4 for supporting the rotating plate 5 are provided on the top of the support rods 8. The support rods 8 provide good support for the support devices 4. The support devices 4 include an annular track 401 fixed to the top of the support rods 8. The annular track 401 is an annular plate with an annular groove on its top surface. Several sliders 402 are slidably connected to the annular track 401 through the annular groove. The sliders 402 are fixedly connected to the rotating plate 5. Therefore, the sliders 402 can provide good support for the rotating plate 5 without hindering its rotation, thus improving the stability of the rotating plate 5.

[0026] The working principle is as follows: the operator places the gloves around the two limiting rods 6. At this time, the two limiting rods 6 limit the handle, thereby fixing the position of the handle. Next, the operator controls the rotary cylinder 2 to drive the lifting plate 10 to rotate, so that the lifting plate 10 rotates to below the bottom handle. Then, the operator controls the linear motor 1 to drive the lifting plate 10 to move upward, thereby causing the lifting plate 10 to move the handle upward, thus raising the handle. Moreover, the distance that the linear motor 1 drives the lifting plate 10 to move upward each time is equal to the height of the handle. Therefore, after the gripping device grips the top handle, the lower handles can rise to the gripping height to achieve automatic handle lifting operation.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
