Flexible bag falling device based on buffering bag falling impact

Abstract

The utility model discloses a flexible bag discharging device based on buffering bag falling impact. The flexible bag unloading device comprises a lattice slide way and a buffer assembly installed on the lattice slide way. The buffering assembly comprises a mounting frame and a plurality of blocking units which are sequentially arranged in the width direction of the grid sliding way. And the blocking unit comprises an overturning piece. The top, located above the lattice opening sliding way, of the overturning piece is rotationally connected with the installation frame. According to the turnover piece structure combining the turnover plate and the soft curtain, the situation that goods are prone to being collided and damaged by a rigid blocking structure can be avoided, and the problems that due to the fact that the long-strip soft curtain is prone to deformation, blocking force is too small, and the long-strip soft curtain cannot be adjusted through a spring can be solved. According to the utility model, the spring exerts elastic force on the turnover piece, so that the blocking force provided by the turnover piece can be increased, and the turnover piece is helped to reset; meanwhile, by changing the connecting position of the spring, the blocking force applied to the goods by the buffering assembly is adjusted.

Description

Technical Field

[0001] This utility model belongs to the field of logistics sorting technology, specifically relating to a flexible unloading device based on mitigating the impact of falling packages. Background Technology

[0002] Narrow-belt sorting machines typically use a chute structure to guide packages from the sorting equipment into the corresponding slots. However, due to differences in sorting speed, package shape, size, and weight, large and heavy packages pose a risk of damage to the package and the slot during drop-off, while also increasing sorting noise. Using a soft curtain as a buffer can reduce the speed of goods to some extent; however, the curtain itself is easily deformable, resulting in insufficient blocking force that cannot be flexibly adjusted (e.g., by spring adjustment), making it difficult to meet the buffering needs of packages of different weights and at different descent speeds. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible packing device based on mitigating the impact of a dropped pack.

[0004] This invention provides a flexible pack unloading device for mitigating the impact of a dropped pack, comprising a grid slide and a buffer assembly mounted on the grid slide. The buffer assembly includes a mounting frame and a plurality of blocking units arranged sequentially along the width direction of the grid slide. Each blocking unit includes a flipping component. The flipping component is rotatably connected to the mounting frame at its top, above the grid slide.

[0005] Preferably, the buffer assembly further includes a support shaft. The support shaft is mounted on a mounting bracket and located directly above the grid slide. The axis of the support shaft is parallel to the width direction of the grid slide. The top of each flipper is rotatably connected to the support shaft.

[0006] Preferably, the blocking unit further includes a fixed bracket. The fixed bracket includes a connecting piece in the middle and support pieces on both sides. The connecting piece in the middle of the fixed bracket is fixed to a corresponding set of mounting holes on the crossbeam. The outer ends of both support pieces of the fixed bracket are provided with shaft limiting grooves. The support shafts are supported at different positions on the shaft limiting grooves of each blocking unit.

[0007] Preferably, the flipping component includes a flipping plate and a soft curtain. The top of the soft curtain is fixed to the bottom of the flipping plate.

[0008] Preferably, both sides of the flip plate are provided with flange structures. The flange structures on the flip plate face the direction in which the goods slide out of the grid slide. The top of the flange structures on both sides of the flip plate is provided with shaft connection holes. The two shaft connection holes are rotatably connected to the support shaft via bushings.

[0009] Preferably, the blocking unit further includes a buffer spring. The two ends of the buffer spring are connected to the mounting bracket and the flipping component, respectively.

[0010] Preferably, the crossbeam of the mounting frame is provided with a first spring connecting structure. The side of the flip plate is provided with a second spring connecting structure. Both the first and second spring connecting structures have spring connecting holes. The connecting hooks at both ends of the buffer spring are connected to the spring connecting holes on the crossbeam of the mounting frame and the flip plate, respectively. At least one of the first and second spring connecting structures has multiple spring connecting holes. By changing the spring connecting holes of the buffer spring, the magnitude of the blocking force can be changed.

[0011] Preferably, the mounting bracket includes a crossbeam and two legs. The bottom of the legs is fixed to both sides of the grid slide. The two ends of the crossbeam are fixed to the tops of the two legs respectively.

[0012] Preferably, the support leg has a U-shaped structure with the opening facing downwards, and its bottom is fixed to the grid slide rail by bolts. The height direction of the support leg is perpendicular to the inclined sliding surface of the inclined section.

[0013] Preferably, the grid slide includes a gradually steepening section, an inclined section, a gradually gentler section, and a horizontal guide section connected sequentially from top to bottom. Along the direction of the wrapping slide, the inclination angle of the gradually steepening section gradually increases, and the inclination angle of the gradually gentler section gradually decreases.

[0014] Preferably, both sides of the grid slide are provided with side baffles to prevent goods from sliding out.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model adds a flip-over component to the grid slide to block and slow down the packages passing through the grid slide, thereby avoiding the problem of the goods sliding out too fast.

[0017] 2. The flipping structure combining the flipping plate and the soft curtain in this utility model can avoid the situation where rigid blocking structures are prone to bumping and damaging goods, and can also avoid the problem that long soft curtains have too little blocking force due to their own easy deformation and cannot be adjusted by springs.

[0018] 3. This utility model applies elastic force to the flipping component through a spring, which can increase the blocking force provided by the flipping component and help the flipping component to return to its original position; at the same time, this utility model adjusts the blocking force applied to the goods by the buffer component by changing the connection position of the spring, thereby adapting to goods of different sizes and weights.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1 As shown, a flexible unloading device for mitigating the impact of falling packages includes a grid slide 1 and a buffer assembly installed in the middle of the grid slide 1. The grid slide 1 includes a gradually steepening section 1-1, an inclined section 1-2, a gradually gentler section 1-3, and a horizontal guide section 1-4 connected sequentially from top to bottom. Along the direction of package sliding, the inclination angle of the gradually steepening section 1-1 gradually increases, while the inclination angle of the gradually gentler section 1-3 gradually decreases, allowing the package to smoothly transition between a horizontal and inclined state. Side baffles are provided on both sides of the grid slide 1 to prevent goods from sliding out.

[0026] like Figure 2 As shown, the buffer assembly includes a mounting frame 2, a support shaft 3, and four blocking units 4 arranged sequentially along the width direction of the grid slide 1. The mounting frame 2 has a gantry structure, including a crossbeam 2-1 and two support legs 2-2. The bottom of the support legs 2-2 is fixed to the side baffle of the grid slide 1. The two ends of the crossbeam 2-1 are respectively fixed to the two support legs 2-2.

[0027] In this embodiment, the support leg 2-2 has a U-shaped structure with the opening facing downwards, and its bottom is fixed to the side baffle by bolts. The support leg 2-2 is perpendicular to the inclined sliding surface of the inclined section 1-2.

[0028] like Figure 2 and 3As shown, the blocking unit 4 includes a fixed bracket 4-1, a flipping component 4-2, and a buffer spring 4-3. The fixed bracket 4-1 is a U-shaped sheet metal part, including a connecting piece in the middle and support pieces on both sides. The connecting piece in the middle of the fixed bracket 4-1 is fixed to the corresponding mounting hole group on the crossbeam 2-1 by bolts and nuts. The outer ends of the two support pieces of the fixed bracket 4-1 are provided with shaft limiting grooves. The support shaft 3 is supported at different positions on the shaft limiting grooves of the four blocking units 4. The four fixed brackets 4-1 provide eight support points for the support shaft 3, so that the support shaft 3 is stably supported.

[0029] The flipping component 4-2 includes a flipping plate 4-2-1 and a soft curtain 4-2-2. Both sides of the flipping plate 4-2-1 have flanged structures. The flanged structures on the flipping plate 4-2-1 face the direction in which the goods slide out of the slot chute 1. The top of the flanged structures on both sides of the flipping plate 4-2-1 has shaft connection holes. The two shaft connection holes are rotatably connected to the support shaft 3 via bushings. The top of the soft curtain 4-2-2 is connected to the bottom of the flipping plate 4-2-1 by bolts or riveting.

[0030] A first spring connecting structure 5 is provided on the crossbeam 2-1 of the mounting frame. A second spring connecting structure 6 is provided on the side of the flipping plate 4-2-1. The first spring connecting structure 5 has multiple spring connecting holes arranged sequentially along the width of the crossbeam 2-1; the second spring connecting structure 6 has spring connecting holes. The connecting hooks at both ends of the buffer spring 4-3 are connected to the spring connecting holes on the crossbeam 2-1 and the flipping plate 4-2-1 of the mounting frame, respectively. By connecting the buffer spring 4-3 to different spring connecting holes on the first spring connecting structure 5, the initial position of the flipping component 4-2 and the preload of the buffer spring 4-3 can be changed, thereby changing the buffering force of the blocking unit 4 on the goods and realizing the adjustment of the bag-dropping buffer.

[0031] In some other embodiments, the second spring connecting structure 6 is provided with a plurality of spring connecting holes arranged sequentially at intervals along the length of the flipping plate 4-2-1. By connecting the buffer spring 4-3 to different spring connecting holes on the second spring connecting structure 6 of the flipping plate 4-2-1, the initial position of the flipping member 4-2 and the preload of the buffer spring 4-3 can be changed, thereby changing the buffering force of the blocking unit 4 on the goods and realizing the adjustment of the bag drop buffer.

[0032] In some embodiments, the crossbeam 2-1 is provided with a greater number of mounting holes and a first spring connection structure 5 than the blocking unit 4; thereby enabling the fixed bracket 4-1 and the buffer spring 4-3 in the blocking unit 4 to be connected at different positions to adjust the position of the blocking unit 4 and realize the adjustment of the density of the flipping parts 4-2. By adjusting the density of the flipping parts 4-2, the buffer assembly can adapt to packages of different sizes, and the number of flipping parts 4-2 in contact with packages of the same size can be adjusted, thereby adjusting the buffering force.

[0033] The distance between the crossbeam 2-1 and the support shaft 3 and the sliding surface of the inclined section 1-2 of the grid slide 1 is greater than the maximum wrapping height. Initially, the distance between the bottom of the flipping component 4-2 and the sliding surface of the inclined section 1-2 of the grid slide 1 is less than the minimum wrapping height. The combined structure of the flipping plate 4-2-1 and the soft curtain 4-2-2 avoids the situation where rigid blocking structures easily bump and damage goods, and also avoids the problem that the long soft curtain 4-2-2 is easily deformed, resulting in insufficient blocking force and inability to be adjusted by springs.

[0034] The working principle of this utility model is as follows:

[0035] The sorting trolley on the sorting machine delivers the goods to the top of the grid slide 1, and the goods slide down the grid slide 1. When the goods reach the buffer component, the flipping plate 4-2-1 and the soft curtain 4-2-2 of the flipping component 4-2 block the sliding goods, and the flipping component 4-2 flips outward under the push of the goods; the blocking of the flipping component 4-2 reduces the falling speed of the goods to a certain extent, and avoids the goods from being damaged by collision due to excessive speed after sliding out; after the goods pass through the flipping component 4-2, the flipping component 4-2 returns to its original position under the elastic force of the spring.
