Description

Technical Field

[0001] This utility model belongs to the field of cargo transportation technology and relates to a shaping device for a bagged cargo production line. Background Technology

[0002] For large quantities of granular or powdery goods, such as cement, fly ash, mineral powder, fertilizer, grain, feed, and chemical raw materials, bag packaging is currently the most common packaging method, which is convenient, fast, and low-cost.

[0003] However, the traditional handling, transfer, and loading / unloading of bagged goods typically relies on manual stacking of each bag, supplemented by certain mechanical equipment for lifting, transfer, and loading / unloading. This not only consumes a lot of manpower and resources, resulting in high labor intensity and low efficiency, but also easily leads to damage to the packaging and loss of goods. With the development of the social economy, the total volume of bagged goods in logistics has also greatly increased, and traditional methods of bagged goods transfer can no longer meet the needs of social development.

[0004] To this end, Chinese patent application (application number: 201611013412.4) discloses a production line for stacking bagged goods, including a transport channel, one end of which is an inlet and the other end is an outlet. The outlet of the transport channel is provided with a double-door device that allows bagged goods to fall sequentially. The key feature is that a transfer track one and a transfer track two are provided parallel to each other below the double-door device. A transfer trolley one capable of reciprocating along the length direction of transfer track one is provided on transfer track one, and a transfer trolley two capable of reciprocating along the length direction of transfer track two is provided on transfer track two. Below the double-door device, there is also a moving track perpendicular to the length direction of transfer track one and / or transfer track two. Transfer track one and transfer track two are arranged on the moving track and are capable of reciprocating along the length direction of the moving track.

[0005] However, the above method has the following drawbacks: 1. During the process of bagged goods falling into the transfer trolley, factors such as gravity and impact force can easily cause changes in the distribution of granular and powdery goods in the bag, thereby causing the bag to deform. 2. When the transfer trolley carrying bagged goods moves on the track, there may be shaking and bumping, which may cause the stacked bagged goods to move relative to each other, thereby causing them to slip or collapse. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a shaping device for a bagged goods production line. The technical problem to be solved by this utility model is: how to stably achieve neat stacking and bundling of bagged goods.

[0007] The objective of this utility model can be achieved through the following technical solution: a shaping device for a bagged goods production line, the production line including a transfer track, two transfer trolleys slidingly arranged on the transfer track, the transfer trolleys including carriages with an upper opening, characterized in that the shaping device includes a shaping frame placed in the carriage and a hoisting mechanism that enables the shaping frame to be placed in or removed from the carriage, and the shaping frame includes a square cylindrical outer plate, the outer wall of the outer plate forming a gap with the inner wall of the carriage.

[0008] During operation, the shaping frame is placed into the carriage by a hoisting mechanism. The frame, under its own weight, presses down on the bottom of the packing bag. At this point, the packing bag passes through the gap between the outer wall of the shaping frame and the inner wall of the carriage, with the bag opening open and folded outward. The bagged goods falling into the carriage are stacked in a neat shape under the constraint of the shaping frame, forming a cube that fits the inner wall of the shaping frame. Then, the shaping frame is removed from the carriage by the hoisting mechanism, and the packing bag is tied up. The outer plate is set in a square tube shape, which better matches the shape of the bagged goods. Under the constraint of the outer plate, no other shaping operation is required, and the bagged goods can be neatly stacked into a cube with a stable structure. Moreover, during the movement of the transfer trolley, the outer plate still constrains the shape of the goods, preventing the stacked bagged goods from slipping or collapsing due to shaking or bumping, further ensuring the stability of the shaping. The outer panel also holds the packing bag down to prevent it from slipping, improving its positioning stability. After the bagged goods are stacked, the outer panel is removed, leaving the goods inside the packing bag. The bag opening remains open and folded outwards. The bag is then tied up to obtain neatly stacked cubic packages. The two transfer trolleys can slide along the transfer track separately, performing different tasks at different positions simultaneously. While one transfer trolley is receiving goods, it can tie up and pack the stacked goods on the other transfer trolley. This alternating operation ensures high efficiency.

[0009] The aforementioned shaping device for a bagged goods production line includes a shaping frame comprising several rectangular, parallel horizontal plates and several rectangular, parallel vertical plates. Each vertical plate is perpendicular to each horizontal plate, and the two outermost vertical plates and the two outermost horizontal plates together form an outer perimeter plate. When the shaping frame is placed inside the carriage, the two outermost vertical plates and the two outermost horizontal plates together form the outer perimeter plate, which, together with the bottom of the carriage, forms a large rectangular cavity. The remaining horizontal and vertical plates further divide this large rectangular cavity into several independent small rectangular cavities. The bagged goods first enter each of the small rectangular cavities. Under the constraint of the horizontal and vertical plates, the goods in each small rectangular cavity will not squeeze against each other. After the shaping frame is removed from the carriage, no further shaping operations are required, and a cubic shape is naturally obtained, which facilitates the neat stacking and bundling of bagged goods.

[0010] The aforementioned shaping device for a bagged goods production line includes a lifting mechanism comprising hooks. The spacing between the longitudinal plates is the same, and the spacing between the transverse plates is also the same. The number of transverse plates is odd, and the middle transverse plate has a mounting hole for the hook to pass through. The mounting hole is located at the middle position of the upper end of this transverse plate. The transverse and longitudinal plates are equidistantly distributed, forming a symmetrical structure. The number of transverse plates is odd, and the lifting point of the hook is located at the middle position of the upper end of the central transverse plate, i.e., at the geometric center of the shaping frame. When the hook is in operation, the lifting point coincides with the center of gravity, preventing the shaping frame from swaying or rotating during ascent or descent. This allows for easy and accurate placement of the shaping frame into the carriage without additional posture adjustments. Furthermore, the shaping frame can leave the carriage filled with goods vertically without colliding with or scratching the goods, preventing deformation or slippage. This facilitates the neat stacking and bundling of bagged goods.

[0011] The aforementioned shaping device for a bagged goods production line includes a lifting mechanism that further comprises a support frame. The hook is mounted on the support frame, and the height of the support frame is more than twice the height of the transfer trolley. The transfer trolley can slide along the transfer track to below the hook. When the transfer trolley moves along the transfer track to below the hook, the hook can lower the shaping frame by hooking it, placing the shaping frame into the carriage. The hook can also raise the shaping frame by hooking it, removing the shaping frame from the carriage.

[0012] The aforementioned shaping device for a bagged goods production line includes a support frame comprising several support legs distributed along the length of the transfer track and slide rails mounted on the support legs. The slide rails extend along the height direction of the support legs. The shaping frame further includes several sliders slidably connected to the slide rails, and the shaping frame can slide back and forth along the height direction of the support legs. The multiple support legs form a stable support structure. During the sliding of the shaping frame along the height direction of the support legs, the slide rails guide the movement of the sliders, facilitating more stable placement or removal of the shaping frame from the carriage.

[0013] The aforementioned shaping device for a bagged goods production line has several upward-facing grooves on the upper side wall of the carriage. The sliders are symmetrically positioned on the outer sides of opposite side walls of the outer perimeter plate and can slide into or out of the grooves along guide rails. During the process of the shaping frame entering or leaving the carriage, the guide rails guide the movement of the sliders. When the shaping frame is placed inside the carriage, the sliders are also located within the grooves, limiting the deflection of the shaping frame and ensuring high stability.

[0014] The shaping device described above for a bagged goods production line has a one-piece molded frame. This one-piece molded structure eliminates the need for complex assembly, calibration, and disassembly. Its internal stress distribution is balanced and stable, and it is not easily affected by temperature changes, vibration, or usage time. Furthermore, the relative positions of the horizontal and vertical plates are fixed during manufacturing, ensuring that the shape and size of the enclosed large and small rectangular chambers remain constant. This facilitates the stable and neat stacking and bundling of bagged goods.

[0015] The aforementioned shaping device for a bagged goods production line has a rectangular cross-section in the horizontal direction of the carriage. The horizontal cross-section of the carriage is rectangular, and the outer panels also have a rectangular cross-section; both shapes are identical. When the shaping frame is suspended above the transfer trolley, aligning the outline of the shaping frame with the outline of the carriage completes the initial positioning. Moving the shaping frame downwards then allows it to be easily placed into the carriage, making operation convenient. When the shaping frame is placed inside the carriage, the four corners of the outer panels are constrained by the carriage, ensuring it maintains its initial correct orientation without deflection, resulting in high stability.

[0016] The aforementioned shaping device for a bagged goods production line includes a lifting mechanism that further comprises a drive unit and a pulley assembly. The drive unit is mounted on a support frame and is capable of driving the pulley assembly to raise and lower the hook in the height direction. Controlling the pulley assembly via the drive unit to adjust the hook's height movement facilitates stable and effortless height adjustment.

[0017] Compared with existing technologies, this shaping device for bagged goods production lines has the following advantages:

[0018] 1. In this shaping device for bagged goods production line, the outer plate is set as a square tube, which is more in line with the shape of the bagged goods. Under the constraint of the outer plate, the bagged goods can be neatly stacked into a cube without other shaping operations. The structure is stable. Moreover, during the movement of the transfer trolley, the outer plate still constrains the shape of the goods, preventing shaking and bumping that could cause the stacked bagged goods to slip or collapse, further ensuring the stability of the shaping.

[0019] 2. In the shaping device used in the bagged goods production line, the outer plate can also press down the packing bag to prevent it from slipping, which improves the positioning stability of the packing bag. After the bagged goods are stacked, the outer plate is removed, and the goods are left in the packing bag. The opening of the packing bag is still open and folded outward. The packing bag is then tied to obtain a neatly stacked cubic package.

[0020] 3. In the shaping device used in the bagged goods production line, two transfer trolleys can slide along the transfer track respectively and perform different tasks at different positions at the same time. When one transfer trolley receives goods, it can bundle and pack the goods stacked on the other transfer trolley. This alternating operation is highly efficient. Attached Figure Description

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0029] like Figure 1 , Figure 2 and Figure 3 It is understood that the shaping device used in the bagged goods production line includes a transport frame and a lifting mechanism 4. The lifting mechanism 4 includes a hook 4a and a support frame 4b. The hook 4a is mounted on the support frame 4b, and the height of the support frame 4b is more than twice the height of the transfer trolley 5. The transfer trolley 5 can slide along the transfer track 3 to below the hook 4a.

[0030] When the transfer trolley 5 moves along the transfer track 3 to below the hook 4a, the hook 4a can hook the shaping frame 5b and lower it to put the shaping frame 5b into the carriage 5a. The hook 4a can also hook the shaping frame 5b and raise it to remove the shaping frame 5b from the carriage.

[0031] The support frame 4b includes two support legs 4b1 distributed along the length of the transfer track 3 and a slide rail 4b2 mounted on the support legs 4b1. The slide rail 4b2 extends along the height of the support legs 4b1. The shaping frame 5b also includes several sliders 5b4 slidably connected to the slide rail 4b2, and the shaping frame 5b can slide back and forth along the height of the support legs 4b1. The multiple support legs 4b1 form a stable support structure. During the sliding of the shaping frame 5b along the height of the support legs 4b1, the slide rail 4b2 guides the movement of the sliders 5b4, which facilitates more stable placement or removal of the shaping frame 5b into or from the carriage 5a.

[0032] The upper side wall of the carriage 5a has several upward-facing grooves 5a. The sliders 5b4 are symmetrically arranged on the outer sides of the opposite side walls of the outer plate 5b1 and can slide into or out of the grooves 5a along the slide rail 4b2. During the process of the shaping frame 5b entering or leaving the carriage 5a, the slide rail 4b2 guides the movement of the sliders 5b4. When the shaping frame 5b is placed inside the carriage 5a, the sliders 5b4 are also located within the grooves 5a, limiting the deflection of the shaping frame 5b and ensuring high stability.

[0033] Specifically, each support leg 4b1 includes two support columns and one crossbeam, with the two support columns located on either side of the transfer track 3. The two support columns and the corresponding crossbeam in each group form a stable portal-shaped load-bearing frame, capable of bearing a high load.

[0034] The hoisting mechanism 4 also includes a drive unit 4c and a pulley assembly 4d. The drive unit 4c is mounted on the support frame 4b and can drive the pulley assembly 4d to raise and lower the hook 4a in the height direction. The pulley assembly 4d includes a pulley and a hanging rope. Controlling the pulley assembly 4d by the drive unit 4c to adjust the raising and lowering of the hook 4a in the height direction is beneficial for achieving stable and labor-saving height adjustment.

[0035] The exit end of the transport rack is equipped with a double-door device that allows bagged goods to fall sequentially. Below the double-door device is a transfer track 3, on which two transfer trolleys 5 slide. Each transfer trolley 5 includes a carriage 5a with an upper opening and a frame 5b placed inside the carriage 5a. The horizontal cross-section of the carriage 5a is rectangular. The frame 5b includes several rectangular parallel horizontal plates 5b2 and several rectangular parallel vertical plates 5b3. Each vertical plate 5b3 is perpendicular to each horizontal plate 5b2, and the two outermost vertical plates 5b3 and the two outermost horizontal plates 5b2 together form an outer perimeter plate 5b1. The outer perimeter plate 5b1 is cylindrical, and a gap is left between the outer wall of the outer perimeter plate 5b1 and the inner wall of the carriage 5a. Since the horizontal cross-section of the carriage 5a is rectangular, the horizontal cross-section of the outer perimeter plate 5b1 is also rectangular, and both have the same shape. When the shaping frame 5b is suspended above the transfer trolley 5, aligning the outline of the shaping frame 5b with the outline of the carriage 5a completes the initial positioning. Then, moving the shaping frame 5b downwards allows it to be smoothly placed into the carriage 5a, making the operation convenient. When the shaping frame 5b is placed inside the carriage 5a, the four corners of the outer panel 5b1 are constrained by the carriage 5a, ensuring it maintains its initial correct orientation without deflection, thus demonstrating high stability. When the shaping frame 5b is placed inside the carriage 5a, the outermost two longitudinal plates 5b3 and the outermost two transverse plates 5b2 together form an outer plate 5b1 that, together with the bottom of the carriage 5a, encloses a large rectangular cavity. The remaining transverse plates 5b2 and longitudinal plates 5b3 further divide the large rectangular cavity into several independent small rectangular cavities. Each small rectangular cavity is just large enough to accommodate a bag of goods laid flat inside. Under the constraint of the transverse plates 5b2 and longitudinal plates 5b3, the goods in each small rectangular cavity will not squeeze each other. After the shaping frame 5b is removed from the carriage 5a, a cubic shape can be naturally obtained without any other operations, which is conducive to the convenient and efficient stacking and bundling of bagged goods.

[0036] The distance between each of the longitudinal plates 5b3 is the same, and the spacing between each of the transverse plates 5b2 is the same. The number of transverse plates 5b2 is odd, and the middle transverse plate 5b2 has a mounting hole 7 for the hook 4a to pass through. The mounting hole 7 is located at the middle position of the upper end of the transverse plate 5b2. The hook 4a is detachably connected to the shaping frame 5b by passing the hook 4a through the mounting hole 7 or by removing the hook 4a from the mounting hole 7. The transverse and longitudinal plates 5b3 are equidistantly distributed to form a symmetrical structure. The number of transverse plates 5b2 is odd, and the lifting point of the hook 4a is located at the middle position of the upper end of the central transverse plate 5b2, that is, the lifting point is located at the geometric center of the shaping frame 5b. When the hook 4a is in operation, the lifting point coincides with the center of gravity, preventing the shaping frame 5b from swaying and rotating during the rising or falling process. This not only eliminates the need for additional posture adjustment, but also allows the shaping frame 5b to be easily and accurately placed into the carriage 5a. Furthermore, the shaping frame 5b can leave the carriage 5a filled with goods vertically without colliding with or scratching the goods, causing them to deform or slip. This facilitates the neat stacking and bundling of bagged goods.

[0037] The shaping frame 5b is a one-piece molded structure. The one-piece molded structure does not require complicated assembly, calibration and disassembly. The internal stress distribution is balanced and stable, and it is not easily changed by temperature changes, vibration and usage time. Moreover, the relative positions between the horizontal and vertical plates 5b3 are fixed during manufacturing, so that the shape and size of the enclosed large and small rectangular cavities remain constant, which is conducive to the stable and neat stacking and bundling of bagged goods.

[0038] During operation, the opening-up packaging bag is first placed in the compartment 5a of one of the transfer trolleys 5. The hook 4a is then passed through the mounting hole 7 to lift the shaping frame 5b, which is then transported into the compartment 5a. The shaping frame 5b, under its own weight, presses down on the bottom of the packaging bag. At this point, the packaging bag passes through the gap between the outer wall of the shaping frame 5b and the inner wall of the compartment 5a, with the bag opening open and folded outwards. After the packaging bag is secured, the hook 4a is removed from the mounting hole 7, allowing the transfer trolley 5 to slide under the double-door device. The bagged goods fall sequentially from the double-door device into the compartment 5a and are stacked in a neat shape under the constraint of the shaping frame 5b. After stacking, the transfer trolley 5 moves to the side, and the shaping frame 5b is removed from the compartment 5a using the hook 4a. Then, the packaging bag is tied. Simultaneously, another transfer trolley 5 with a secured packaging bag moves to the bottom of the double-door device, and this process is repeated alternately.

[0039] The shaping frame 5b is placed into the carriage 5a by hook 4a. The shaping frame 5b can not only fix the packing bag in the carriage 5a by its own weight, preventing it from slipping and improving the positioning stability of the packing bag, but also shape the bagged goods by its own shape, so that they are stacked in sequence according to the outline of the shaping frame 5b to form a regular cube. This makes it convenient and efficient to stack the bagged goods neatly. After stacking, the shaping frame 5b is removed from the carriage 5a by hook 4a. At this time, the opening of the packing bag is still open and folded outward, and the bagged goods are neatly stacked inside the packing bag. The packing bag is then tied up, which makes it convenient and efficient to tie up and pack the bagged goods neatly. Bagged goods are stacked one by one under the limiting effect of the shaping frame 5b, and the outer plate 5b1 can also press down the packing bags to prevent them from slipping, improving the positioning stability of the packing bags. After the bagged goods are stacked, the outer plate 5b1 is removed, leaving the goods in the packing bags. The opening of the packing bags remains open and is folded outwards. The packing bags are then tied up to obtain neatly stacked cubic-shaped packages. In addition, during the movement of the transfer trolley 5, the outer plate 5b1 continues to constrain the shape of the goods, preventing shaking or bumping that could cause the stacked bagged goods to slip or collapse, further ensuring the stability of the shaping. The two transfer trolleys 5 can slide along the transfer track 3 respectively, performing different tasks at different positions simultaneously. When one transfer trolley 5 moves to receive goods under the double-door device, it bundles and packs the goods on the other transfer trolley 5. This alternating work is highly efficient.

[0040] Although this document frequently uses terms such as transfer track 3, hoisting mechanism 4, hook 4a, support frame 4b, support foot 4b1, slide rail 4b2, driving component 4c, pulley assembly 4d, transfer trolley 5, carriage 5a, groove 5a1, shaping frame 5b, outer plate 5b1, horizontal plate 5b2, vertical plate 5b3, slider 5b4, and mounting hole 7, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
