Description

Technical Field

[0001] The utility model belongs to the field of automation equipment, and particularly relates to a bin sorting mechanism. Background Art

[0002] During the process of product boxing, folding the sealing cardboard at the top of the carton outwards is a key step to ensure the smooth boxing of products. Traditional carton sorting mechanisms usually use blades arranged at the four corners of the carton in cooperation with a driving mechanism to fold the cardboard. These blades are generally designed in an obtuse angle shape, expecting to achieve a larger contact area with the cardboard, and can guide the cardboard to fold outwards under the action of the driving mechanism. However, this design has exposed some problems in practical applications.

[0003] Firstly, due to the complexity of the carton material and the folding angle of the cardboard, it is often difficult for the obtuse blades to ensure a stable folding effect when folding the cardboard. Especially when the cardboard is relatively hard or the friction between the cardboard and the blades is insufficient, the cardboard is likely to break away from the folding action of the blades during the folding process, thus affecting the boxing of products. Secondly, each blade needs to cooperate with the driving mechanisms arranged in two directions to realize folding the cardboard downwards and outwards from the carton, which will result in the use of more driving parts and increase the equipment cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bin sorting mechanism that can improve the folding effect of the cardboard and reduce the equipment cost.

[0021] As Figure 1 As shown, the bin sorting mechanism includes two groups of folding assemblies 100 arranged at the diagonals of the bin 10. At least two groups of folding assemblies 100 are provided and arranged at the diagonals of the bin 10, which can act on the four sealing cardboards 11 at the top of the bin 10 simultaneously at the diagonals of the bin 10. In other embodiments, the folding assemblies 100 can also be provided in three groups or four groups and arranged at different corners of the bin 10 respectively. Each group of folding assemblies 100 includes a bracket 110, a rotary cylinder 120 arranged on the bracket 110, a connecting arm 130 connected to the rotary cylinder 120, and a pressing rod 140 connected to the connecting arm 130. The pressing rod 140 is perpendicular to the connecting arm 130, and both ends of the pressing rod 140 abut against the sealing cardboard 11 of the bin 10. The connecting arm 130 rotates around the rotation axis of the rotary cylinder 120, driving the pressing rod 140 to approach or move away from the sealing cardboard 11, and the pressing rod 140 is always parallel to the horizontal plane. Two groups of folding assemblies 100 are arranged at the diagonals of the bin 10. Each group of folding assemblies 100 folds the adjacent sealing cardboard 11 through a rotary cylinder 120 and a pressing rod 140. The structure is simple, the cost is low, and the folding effect is good.

[0022] As Figure 2As shown, the folding assembly 100 further includes a top plate 150 installed on the top of the bracket 110 and a side plate 160 connecting the top plate 150 and the rotary cylinder 120. The top plate 150 is provided with an arc-shaped groove 151 and a mounting hole 152 penetrating through the top plate 150. The side plate 160 is connected to the mounting hole 152 and the arc-shaped groove 151 by screws, and the rotary cylinder 120 is installed on the side plate 160. The side plate 160 can rotate along the arc-shaped groove 151 with the mounting hole 152 as the center, changing the position of the side plate 160, and further changing the position of the pressing rod 140 to adapt to bins 10 of different sizes.

[0023] As Figure 3 shown, a first waist-shaped hole 161 is provided through the side plate 160. The first waist-shaped hole 161 is arranged along the longitudinal direction A, and the installation position of the rotary cylinder 120 along the longitudinal direction A is changed to adapt to bins 10 of different heights.

[0024] Referring again to Figure 1 shown, rolling members 170 are respectively rotatably connected to both ends of the pressing rod 140. The rolling members 170 are in rolling contact with the sealing cardboard 11, avoiding damage to the sealing cardboard 11 at the joints between the two ends of the pressing rod 140 and the sealing cardboard 11. The rolling members 170 can be set as deep groove ball bearings, rollers, etc. An anti-slip ring is arranged on the outer surface of the rolling members 170, and the anti-slip ring is made of rubber to increase the friction between the rolling members 170 and the sealing cardboard 11, avoiding the sealing cardboard 11 getting out of control of the rolling members 170.

[0025] The two folding assemblies 100 and the bin 10 have relative movement to fold the sealing cardboard 11 of different bins 10. It can be the movement of the two folding assemblies 100 or the movement of the bin 10. In this embodiment, the bin 10 is conveyed between the two folding assemblies 100 through the conveying assembly 200. The conveying assembly 200 has a feeding end and a discharging end along the bin conveying direction B, and the bin 10 is conveyed from the feeding end to the discharging end. The conveying assembly 200 is arranged between the two folding assemblies 100 and includes a mounting bottom plate 210, two vertical plates 220 perpendicular to the mounting bottom plate 210, and a plurality of conveying rollers 230 rotatably arranged on the two vertical plates 220. The plurality of conveying rollers 230 are connected to each other and can rotate passively. The bin 10 is driven to the conveying assembly 200 at the previous station, and the plurality of conveying rollers 230 rotate driven by the bin 10 to receive the bin 10. In other embodiments, the plurality of conveying rollers 230 are connected to each other and can also be driven to rotate actively, and stop rotating after continuously conveying the bin 10 in place.

[0026] As Figure 3As shown in the figure, the conveying assembly 200 further includes a baffle plate 240 that is perpendicular to both the mounting base plate 210 and the two vertical plates 220. At least one first connecting plate 250 is provided on the baffle plate 240, and a buffer pad 260 is provided on the first connecting plate 250. The two vertical plates 220 are arranged along the material box conveying direction B, and the baffle plate 240 is arranged at the discharging end of the conveying assembly 200 to prevent the continuous conveying of the material box 10. The buffer pad 260 is made of resin material, has high wear resistance and elasticity, and plays a role of blocking and buffering for the material box 10.

[0027] Two second connecting plates 270 are provided on the baffle plate 240, and a first driving member 280 is provided on each of the second connecting plates 270. The driving end of the first driving member 280 is connected with a first L-shaped limiting plate 290, and the first L-shaped limiting plate 290 abuts against the side edge of the material box 10 facing the baffle plate 240. The first driving member 280 is preferably a cylinder, and its driving direction extends along the longitudinal direction A to drive the first L-shaped limiting plate 290 to adapt to material boxes 10 of different heights. The arrangement of the two first L-shaped limiting plates 290 can prevent the material box 10 from tipping over when the folding assembly 100 folds the sealing cardboard 11.

[0028] The material box 10 has a front surface 12, a rear surface 13, a left surface 14 and a right surface 15. After the material box 10 is conveyed in place, the front surface 12 faces the feeding end of the material box 10, the rear surface 13 abuts against the buffer pad 260, and the two first L-shaped limiting plates 290 are arranged oppositely and respectively abut against the side edges formed by the rear surface 13 and the left surface 14, and the rear surface 13 and the right surface 15.

[0029] A first folding surface 291 is provided at the top of the first L-shaped limiting plate 290, and a second folding surface 292 is provided at the end of the first L-shaped limiting plate 290 facing the feeding end. The first folding surface 291 plays a guiding role when the first L-shaped limiting plate 290 rises and falls to avoid damaging the material box 10. The second folding surface 292 guides the side wall of the material box 10 between the two first L-shaped limiting plates 290 when the conveying assembly 200 conveys the material box 10.

[0030] A fourth connecting plate 293 is provided at the bottom of the first L-shaped limiting plate 290, and a second waist-shaped hole 2931 is provided through the fourth connecting plate 293. The second waist-shaped hole 2931 is arranged along the axial direction C of the conveying roller. The first L-shaped limiting plate 290 is installed at the driving end of the first driving member 280 through the second waist-shaped hole 2931 and changes the installation position to adapt to material boxes 10 of different sizes.

[0031] A third waist-shaped hole 271 is provided through the second connecting plate 270. The third waist-shaped hole 271 is arranged along the longitudinal direction A. The first driving member 280 is installed on the second connecting plate 270 through the third waist-shaped hole 271 and changes the installation position to adapt to material boxes 10 of different sizes.

[0032] Reference again Figure 1 As shown, the upper surface of the vertical plate 220 is provided with a second driving member 221, and the driving end of the second driving member 221 is connected to the second L-shaped limiting plate 222. The second driving member 221 drives the second L-shaped limiting plate 222 to flip away from or abut against the side edge of the material box 10 away from the blocking plate 240. The second driving member 221 is preferably a side cylinder, and its driving direction extends along the material box conveying direction B. When the second driving member 221 is in the extended position, the material box 10 is not restricted. When the second driving member 221 is in the retracted position, the two second L-shaped limiting plates 222 and the two first L-shaped limiting plates 290 are limited to prevent the material box 10 from tilting or moving when the folding assembly 100 folds the sealing paperboard 11.

[0033] The second driving member 221 can change its position along the axial direction C of the conveying roller through the connecting plate, the waist-shaped hole set on the connecting plate, etc. to adapt to the material box 10 of different sizes. The specific installation method will not be repeated here.

[0034] A guide rod 223 is provided through the vertical plate 220, and the guide rod 223 extends along the axial direction C of the conveying roller. A guide plate 224 is provided at the end of the guide rod 223 facing the material box 10, and an inclined guide surface 2241 is provided at one end of the guide plate 224 away from the blocking plate 240, that is, the guide surface 2241 is provided at the feed end of the guide plate 224 close to the conveying assembly 200. In order to ensure the stable sliding of the guide plate 224, at least two guide rods 223 are provided through the vertical plate 220. The two guide plates 224 are in contact with the left surface 14 and the right surface 15 of the material box 10 respectively.

[0035] The distance between the two guide rods 223 can be manually adjusted to adapt to different sizes of material boxes 10, and the material box 10 is introduced into a suitable position. The sliding of the guide rod 223 is adjusted, and after being adjusted to a suitable position, the guide rod 223 is locked.

[0036] The distance between the two guide plates 224 can also be adjusted by a driving member. One of the guide plates 224 can be fixed, and the other guide plate 224 can be driven to move by a driving member; or the two guide plates 224 can be driven to move by two driving members. Therefore, at least one vertical plate 220 is provided with a third driving member 225. In this embodiment, the third driving member 225 is provided on the vertical plate 220 close to the right surface 15, and the end of the guide rod 223 away from the material box 10 is provided with a third connecting plate 226, and the driving end of the third driving member 225 is connected to the third connecting plate 226. The third driving member 225 is preferably a cylinder, and its driving direction extends along the axial direction C of the conveying roller.

[0037] The mounting base plate 210 is slidably mounted on a substrate 310 through a slide rail 300. A fourth driving member 320 is also provided on the substrate 310.

The two layers of conveyor belts 500 are arranged on the side of the conveying assembly 200, and the conveying directions of the two layers of conveyor belts 500 are opposite. For example, the upper conveyor belt 500 conveys the bin 10 to the conveying assembly 200. After the folding assembly 100 folds the sealing cardboard 11, the product is loaded into the bin 10. Subsequently, the fourth driving member 320 drives the conveying assembly 200 to move down to the lower conveyor belt 500, and the lower conveyor belt 500 conveys the bin 10 located on the conveying assembly 200 out. In other embodiments, the conveying directions of the two layers of conveyor belts 500 can also be set to be opposite. After the product is loaded into the bin 10, the fourth driving member 320 drives the conveying assembly 200 to move up to the upper conveyor belt 500, and the upper conveyor belt 500 conveys the bin 10 located on the conveying assembly 200 out. The function of the fourth driving member 320 to drive the bin 10 to move longitudinally is to facilitate the continuous conveyance of the bin 10 past two sets of folding assemblies 100.

[0039] Sensors 400 are provided on the upper surfaces of the blocking plate 240 and the two vertical plates 220 to detect whether the sealing cardboard 11 is folded in place. The sensors 400 adopt diffuse reflection type sensors, and their transmitting ends and receiving ends both face the sealing cardboard 11. After setting the positions of the sensors 400, when the cardboard is folded in place, the cardboard reflects part of the light, and after the receiving end receives the light, it converts the optical signal into an electrical signal to confirm that the cardboard is folded in place. The sensors 400 are installed through a connecting plate. The connecting plate is provided with waist-shaped holes, and the installation positions of the sensors 400 are adjusted through the connecting plate so that the sensors 400 can detect whether the sealing cardboard 11 is folded in place according to the different sizes of the bin 10.
