Description

Technical Field

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

[0002] In logistics, chemical, and food industries, woven bags are commonly used packaging containers, and their post-production palletizing is a crucial step in ensuring efficient warehousing and transportation. Currently, woven bag palletizing largely relies on manual labor or semi-automatic palletizing devices. Semi-automatic palletizing devices, due to their higher efficiency, have gradually replaced some manual operations. Existing semi-automatic woven bag palletizing devices typically include a base, a conveyor structure, and a placement platform. The conveyor structure transports the woven bags to the placement platform for stacking. To prevent the stacked bags from shifting, the placement platform is usually equipped with limiting components such as uprights.

[0003] However, existing palletizing devices have significant shortcomings in adapting to woven bags of different widths. The limiting rods are mostly fixed installation structures, or the width adaptation range can only be adjusted by manually disassembling and replacing limiting components with different spacings. When it is necessary to palletize woven bags of different specifications, the operator needs to stop the machine to perform tedious disassembly and replacement of parts, which is not only time-consuming and labor-intensive, interrupting the continuous palletizing operation process and reducing the overall palletizing efficiency, but also increasing the labor operation cost. Utility Model Content

[0004] The main purpose of this utility model is to provide a woven bag palletizing device, which drives a first shaft, sprocket and chain transmission through a first servo motor to move the upright along the through groove of the placement platform. The distance between the upright and the base can be adjusted according to the width of the woven bag, which can adapt to the palletizing needs of woven bags of different specifications. No special parts need to be replaced, and it has a wide range of applications.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A woven bag palletizing device includes a base and a hollow placement platform located on one side of the base. Several sets of conveying components are arranged on the top of the base. The height of the placement platform is lower than that of the base. At least two first shafts are rotatably connected inside the placement platform. Two sprockets are installed on the first shafts. Matching sprockets on the two first shafts are connected by a chain. A vertical rod is fixed to the upper end of the chain. Several through slots are opened on the top of the placement platform. The vertical rod passes through the through slots. A first servo motor is fixed to one side of the placement platform. The drive end of the first servo motor is fixedly connected to one of the first shafts.

[0006] Furthermore, the conveying assembly includes several grooves formed on the top of the base, each groove containing a first roller. The several first rollers are connected to each other via a second shaft. A second servo motor is fixed to one side of the base, and the output shaft of the second servo motor is fixedly connected to the second shaft.

[0007] Furthermore, the conveying assembly also includes two upright plates fixed to the top of the base, with a third shaft rotatably connected between the upright plates, and a second roller that contacts the first roller fixedly connected to the third shaft.

[0008] Furthermore, a guide rocker is fixed to one end of the base near the placement platform.

[0009] Furthermore, the cross-section of the guide rocker is triangular.

[0010] Furthermore, the top height of the first roller is 1-5 mm higher than the top surface height of the base.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model uses a first servo motor to drive a first shaft, sprocket, and chain transmission to move the upright along the slot of the placement platform. It can adjust the distance between the upright and the base according to the width of the woven bag, and can adapt to the stacking requirements of woven bags of different specifications. It does not require the replacement of special parts and has a wide range of applications.

[0012] The guide rocker of this invention can give the woven bag an upward angle, so that it has an upward tendency when it is detached from the base, and finally falls horizontally onto the placement platform.

[0013] The second servo motor of this invention drives the second shaft to rotate the first roller, and the first roller cooperates with the oppositely arranged second roller to stably clamp and transport thinner woven bags, avoiding the woven bags from shifting or slipping during the transport process.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] like Figure 1-5As shown, a woven bag palletizing device includes a base 1 and a hollow placement platform 2 located on one side of the base 1. Several sets of conveying components are provided on the top of the base 1. The height of the placement platform 2 is lower than that of the base 1. At least two first shafts 14 are rotatably connected inside the placement platform 2. Two sprockets 13 are installed on the first shafts 14. The matching sprockets 13 on the two first shafts 14 are connected by a chain 5. A vertical rod 3 is fixed to the upper end of the chain 5. Several through slots 12 are opened on the top of the placement platform 2. The vertical rod 3 passes through the through slots 12. A first servo motor 4 is fixed on one side of the placement platform 2. The drive end of the first servo motor 4 is fixedly connected to one of the first shafts 14.

[0025] In this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the woven bags are conveyed from the base 1 by the conveying assembly, so that the woven bags fall onto the placement platform 2. Since the top of the placement platform 2 has two uprights 3, the uprights 3 can limit the woven bags falling onto the placement platform 2, so that the woven bags are stacked neatly and the woven bags are stacked.

[0026] Furthermore, the first servo motor 4 can drive a certain first shaft 14 to rotate, thereby driving the two sprockets 13 on this shaft to rotate, and then driving the two sprockets 13 on another first shaft 14 to rotate through the chain 5, thereby realizing the transmission operation of the chain 5. As the chain 5 is conveyed, the distance between the upright 3 and the base 1 can be changed, so that the personnel can adjust the distance between the upright 3 and the base 1 according to the width of the woven bag, so that this distance is just slightly larger than the width of the woven bag, to ensure that the woven bags are stacked neatly.

[0027] A limiting plate can be bolted to the top of the placement platform 2 along the length of the first shaft 14 to limit the two ends of the woven bag (not shown in the figure).

[0028] When the first servo motor 4 drives the chain 5, the transmission of the chain 5 should be observed to ensure that the upright pole 3 is always in a vertical state.

[0029] Fixing other structures (such as uprights 3) to chain 5 is existing technology in this field and will not be elaborated on here.

[0030] like Figure 1 and Figure 4 As shown, the conveying assembly includes several grooves 8 opened on the top of the base 1, and first rollers 7 are arranged in the grooves 8. The several first rollers 7 are connected to each other by a second shaft 16. A second servo motor 6 is fixed on one side of the base 1. The output shaft of the second servo motor 6 is fixedly connected to the second shaft 16. The other end of the second shaft 16 is rotatably connected to the base 1 through a bearing. The top height of the first rollers 7 is 1-5 mm higher than the top surface height of the base 1.

[0031] When the second servo motor 6 is working, it can drive the second shaft 16 to rotate, thereby driving the first roller 7 to rotate. When the woven bag is located on top of the first roller 7, the first roller 7 can transport the woven bag.

[0032] The conveying assembly also includes two upright plates 11 fixed to the top of the base 1. A third shaft 10 is rotatably connected between the upright plates 11. A second roller 9 that contacts the first roller 7 is fixedly connected to the third shaft 10. Both the first roller 7 and the second roller 9 are rubber rollers with a certain deformation capability. Since the woven bag is thin, it can be inserted between the first roller 7 and the second roller 9. Therefore, when the first roller 7 rotates, the second roller 9 can cooperate with the first roller 7 to convey the woven bag.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, a guide rocker plate 15 is fixed at one end of the base 1 near the placement platform 2. The cross-section of the guide rocker plate 15 is triangular. When the woven bag passes the guide rocker plate 15, the guide rocker plate 15 will give the woven bag an upward angle, so that the woven bag has an upward tendency when it leaves the base 1, and thus the woven bag can fall horizontally on the placement platform 2, avoiding the situation where the woven bag folds when it falls on the placement platform 2 due to insufficient horizontality.

[0034] Working principle: The second servo motor 6 is activated, driving the second shaft 16 to rotate, which in turn drives the first roller 7 to rotate. Simultaneously, the second roller 9 works in conjunction with the first roller 7 to stably convey the woven bag forward. When the woven bag is conveyed close to the placement platform 2, the guide rocker 15 gives the woven bag an upward angle, causing it to tend to move upwards when it leaves the base 1, preventing it from folding due to unevenness when falling onto the placement platform 2. The woven bag, guided by the guide rocker 15, falls horizontally onto the placement platform 2. At this point, the upright 3, fixed to the chain 5, guides the woven bag onto the placement platform 2. The distance between the upright 3 and the base 1 needs to be adjusted according to the width of the woven bag. The first servo motor 4 is started, which drives the first shaft 14 connected to it to rotate. The sprocket 13 on the first shaft 14 drives the matching sprocket 13 on another first shaft 14 to rotate synchronously through the chain 5. The chain 5 drives the upright 3 to move along the through groove 12, so that the distance between the upright 3 and the base 1 is slightly greater than the width of the woven bag. Under the limiting action of the adjusted upright 3, the woven bags that fall horizontally to the placement platform 2 continue to be stacked, and finally the woven bags are neatly stacked to complete the stacking operation.

[0035] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
