Description

Technical field

[0001] The present invention relates to the technical field of filling, and in particular to a transporting and conveying device. [Background Technology]

[0002] The existing conveyor system used to transport cans to the filling station consists of a conveyor belt and guide rods positioned on either side of the belt, gradually approaching each other along the conveying direction. During operation, multiple rows of cans are placed on the conveyor belt. The guide rods guide the cans into a single row, which is then conveyed to the filling station in a single file. As the guide rods guide the cans into a single file, adjacent cans can be squeezed. This conveying method can result in cosmetic defects on high-value cans with surfaces featuring special brushed textures, oxidized coloring, or fine relief patterns. [Summary of the invention]

[0007] In the above-mentioned handling and conveying device, the group docking assembly includes a first lifting mechanism, a carrier plate, a first suction unit and a rotating mechanism. The first lifting mechanism drives the carrier plate to rise and fall. The first suction unit is rotatably installed on the carrier plate. The first suction unit includes a plurality of first suction cups corresponding one to one to the positioning bosses in the positioning unit. The rotating mechanism is installed on the carrier plate and drives the first suction unit to rotate so that the first suction cup is flipped up and down.

[0008] In the above-mentioned handling and conveying device, the first suction unit further includes a limiting plate that rotates synchronously with the first suction cup, and the limiting plate is provided with limiting holes that correspond one-to-one with the first suction cup, and the sucked packaging cans pass through the limiting holes.

[0009] In the above-mentioned handling and conveying device, the tank feeding conveying mechanism includes a first supporting guide rail, a first synchronous belt, a first mounting plate connected to the first synchronous belt, and a first driving mechanism for driving the first synchronous belt to move. The first driving mechanism drives the first synchronous belt to move so that the first mounting plate slides back and forth along the first supporting guide rail, and the positioning unit is arranged on the first mounting plate.

[0010] In the above-mentioned handling and conveying device, the conveying direction of the tank inlet conveying mechanism is parallel to the conveying direction of the tank outlet conveying mechanism, multiple groups of positioning units are arranged along the conveying direction perpendicular to the tank inlet conveying mechanism, the group connection assembly performs lifting and translational movement above the output end station of the tank inlet conveying mechanism, and the group handling assembly performs lifting and translational movement between the group connection assembly and the tank outlet conveying mechanism.

[0011] In the above-mentioned handling and conveying device, the group handling component includes a second suction unit and a second driving mechanism for driving the second suction unit to rise, fall and translate. The second suction unit includes a plurality of second suction cups corresponding one-to-one to the positioning bosses in a single positioning unit. The second suction cups absorb a row of packaging cans on the group docking component each time.

[0012] In the above-mentioned handling and conveying device, the second driving mechanism includes a second supporting guide rail, a second synchronous belt, a second mounting plate connected to the second synchronous belt, a second translation unit, and a second lifting unit installed on the second mounting plate.

[0014] In the above-mentioned handling and conveying device, the positioning boss is a frustum that gradually shrinks upwards.

[0015] Beneficial effects of the present invention:

[0016] The can feeding and conveying mechanism of the present invention includes a plurality of groups of positioning units arranged in parallel, each group of positioning units includes at least two rows of positioning bosses, and the positioning bosses of two adjacent rows are staggered, and the packaging cans are inverted on the positioning bosses. With this design, the packaging cans can be positioned by the positioning bosses, so that the packaging cans are placed on the can feeding and conveying mechanism at intervals, so as to prevent adjacent packaging cans from contacting and squeezing each other, thereby avoiding appearance defects of the packaging cans during the conveying process, so as to ensure the appearance of the packaging cans; in addition, the staggered distribution of the positioning bosses of two adjacent rows can enable the can feeding and conveying mechanism to convey more packaging cans, so as to improve the conveying efficiency of the conveying and conveying device; in addition, the conveying mechanism includes The group connecting component and the group transporting component, the group connecting component absorbs a group of packaging cans on the positioning unit each time and flips the packaging cans to an upright state. This design allows the inner bottom wall of the packaging can to become the adsorption site of the group transporting component, thereby facilitating the adsorption of the group transporting component and improving the adsorption reliability of the group transporting component. At the same time, the packaging cans are in an upright state, which is also convenient for subsequent filling; finally, the group transporting component absorbs a row of upright packaging cans each time and transports the packaging cans to place them on the can discharge conveying mechanism. This design allows the packaging cans to be transported in a single row on the can discharge conveying mechanism, thereby matching the existing filling mechanism and improving the filling efficiency.

[0017] The conveying direction of the can inlet conveying mechanism is perpendicular to the conveying direction of the can outlet conveying mechanism. Multiple groups of positioning units are arranged along the conveying direction of the can inlet conveying mechanism. The group connection assembly is located above the output end station of the can inlet conveying mechanism and performs lifting and lowering movements. The group handling assembly performs lifting and translational movements between the group connection assembly and the can outlet conveying mechanism. With this design, each time the group connection assembly sucks away the packaging cans on a group of positioning units, the can inlet conveying mechanism is fed forward a certain distance so that the packaging cans of a group of positioning units are just located below the group connection assembly, so that the next time the group connection assembly descends and sucks the packaging cans on a group of positioning units, it can be seen that by controlling the feeding distance of the can inlet conveying mechanism, the group connection assembly can suck the packaging cans only by lifting and lowering, without the need for the group connection assembly to translate. This eliminates the translation structure that drives the translation of the group connection assembly, thereby simplifying the depalletizing equipment and reducing manufacturing costs.

[0018] The group docking assembly includes a first lifting mechanism, a carrier, a first suction unit, and a rotation mechanism. The first lifting mechanism drives the carrier up and down, and the first suction unit is rotatably mounted on the carrier. The first suction unit includes multiple first suction cups that correspond one-to-one with the positioning bosses in the positioning unit. The rotation mechanism is mounted on the carrier and drives the first suction unit to rotate, causing the first suction cups to flip up and down. With this design, the first lifting mechanism drives the carrier down, allowing the first suction unit to pick up the can and then drive the carrier up and back to its original position. The rotation mechanism then drives the first suction unit to rotate, flipping the can to an upright position. This results in a relatively simple structure and control program.

[0019] The first suction unit also includes a stopper plate that rotates synchronously with the first suction cup. The stopper plate is equipped with stopper holes that correspond one-to-one with the first suction cup, and the cans being sucked pass through the stopper holes. This design prevents the cans from tilting during the flipping process and ensures that the cans remain upright after flipping, facilitating smooth pickup of the upright cans by the subsequent grouping and handling assembly.

[0020] The can-feeding conveyor mechanism includes a first support rail, a first timing belt, a first mounting plate connected to the first timing belt, and a first drive mechanism for driving the first timing belt. The first drive mechanism drives the first timing belt to cause the first mounting plate to slide back and forth along the first support rail. The positioning unit is located on the first mounting plate. This design offers a simple structure, low manufacturing cost, and is suitable for long-distance conveying.

[0021] The grouped handling assembly includes a second suction unit and a second drive mechanism for driving the second suction unit in both vertical and horizontal movements. The second suction unit includes multiple second suction cups that correspond one-to-one with the positioning bosses in the individual positioning units. Each second suction cup grasps a row of cans from the grouped docking assembly. Because the distribution and number of cans in each row vary, the second suction unit is designed to include multiple second suction cups that correspond one-to-one with the positioning bosses in the individual positioning units. This allows the second suction unit to grasp a row of cans from the grouped docking assembly simply by controlling the second suction unit to move above the grouped docking assembly and control the row of second suction cups corresponding to that row of cans to grasp the cans, resulting in a relatively simple control process.

[0022] The second drive mechanism includes a second support rail, a second synchronous belt, a second mounting plate connected to the second synchronous belt, a second translation unit, and a second lifting unit mounted on the second mounting plate. The second translation unit drives the second synchronous belt to move, causing the second mounting plate to slide back and forth along the second support rail. The second suction unit is mounted below the second mounting plate, and the second lifting unit drives the second suction unit up and down. This design allows for independent control of the second lifting unit and the second translation unit, simplifying the control process and reducing the occurrence of control failures.

[0023] The can delivery conveyor mechanism includes a can delivery conveyor belt, a support member, a plurality of mold boxes slidably mounted on the can delivery conveyor belt and used to accommodate packaging cans, and a front can blocking assembly and a rear can blocking assembly mounted on the support member. The support member supports the can delivery conveyor belt. The front and rear can blocking assemblies are used to block the feeding of the mold boxes so that the number of mold boxes between the front and rear can blocking assemblies is the same as the number of packaging cans picked up by the grouping and handling assembly. This design, by placing the packaging cans in the mold boxes, not only separates the packaging cans in a row to prevent adjacent packaging cans from contacting and squeezing each other, but also prevents the packaging cans from tilting during transportation, thereby facilitating subsequent filling. Finally, the design of the front and rear can blocking assemblies ensures that all packaging cans picked up by the grouping and handling assembly are placed in the mold boxes, and prevents some mold boxes from being empty, which would affect subsequent filling.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0041] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0042] Example 1

[0043] Reference Figures 1 to 8 As shown, the handling and conveying device in this embodiment is installed on the frame 100, and the handling and conveying device includes a tank inlet conveying mechanism 200, a handling mechanism 300 and a tank outlet conveying mechanism 400, wherein the handling mechanism 300 is arranged between the output end station of the tank inlet conveying mechanism 200 and the input end station of the tank outlet conveying mechanism 400, and the tank inlet conveying mechanism 200 includes a plurality of groups of parallel positioning units 210, each group of positioning units 210 includes at least two rows of positioning bosses 211, and the two adjacent rows of positioning bosses 211 are staggered, and the packaging can 001 is upside down on the positioning bosses 211. With such a design, the packaging can 001 can be positioned by the positioning bosses 211, so that the packaging can 001 is placed on the tank inlet conveying mechanism 200 at intervals to prevent adjacent packaging cans 001 from contacting and squeezing, thereby avoiding appearance defects of the packaging can 001 during transportation to ensure the packaging The appearance of the cans 001 is beautiful; the conveying mechanism 300 includes a group connecting component 310 and a group conveying component 320. The group connecting component 310 absorbs a group of packaging cans 001 on the positioning unit 210 each time and flips the packaging cans 001 to an upright state. With this design, the inner bottom wall of the packaging can 001 can become the adsorption part of the group conveying component 320, thereby facilitating the adsorption of the group conveying component 320 and improving the adsorption reliability of the group conveying component 320. At the same time, the packaging cans 001 are in an upright state, which is also convenient for subsequent filling; finally, the group conveying component 320 absorbs a row of upright packaging cans 001 each time and conveys the packaging cans 001 to be placed on the can delivery mechanism 400. With this design, the packaging cans 001 can be transported in a single row on the can delivery mechanism 400, thereby matching the existing filling mechanism and improving the filling efficiency.

[0044] Specifically, the frame 100 in this embodiment includes a lower frame 110, a middle frame 120 and an upper frame 130, wherein the can feeding conveying mechanism 200 includes a first support guide rail 270, a first synchronous belt 220, a first mounting plate 230 and a first driving mechanism. There are two first support guide rails 270, and the two first support guide rails 270 are arranged in parallel and spaced apart and installed on the middle frame 120. The first support guide rail 270 extends along the length direction of the middle frame 120. The first mounting plate 230 has a first guide groove that slides with the first support guide rail 270. A plurality of positioning bosses 211 are installed on the first mounting plate 230. The positioning boss 211 is a cone that gradually shrinks upward to facilitate the packaging can 001 to be inverted on the positioning boss 211. The first mounting plate 230 is provided with a mounting groove, and the bottom of the positioning boss 211 is embedded in the mounting groove. The first driving mechanism includes a first motor 240, a first main pulley 250 and a first secondary pulley 260. The first synchronous belt 220 is wound around the first main pulley 250 and the first secondary pulley 260 and is connected to the first mounting plate 230. The first main pulley 250 is connected to the first motor 240. The first motor 240 is mounted on the middle frame 120. The first secondary pulley 260 is rotatably mounted on the middle frame 120. The first motor 240 drives the first synchronous belt 220 to move to drive the first mounting plate 230 to slide back and forth along the first support rail 270. Preferably, in this embodiment, the conveying direction of the can inlet conveying mechanism 200 is perpendicular to the conveying direction of the can outlet conveying mechanism 400, that is, the sliding direction of the first mounting plate 230 is perpendicular to the conveying direction of the can outlet conveying mechanism. At this time, Figure 4 As shown, the plurality of positioning units 210 are arranged along the sliding direction of the first mounting plate 230 .

[0045] Secondly, if Figures 5 to 7As shown, the group docking assembly 310 in this embodiment is located above the output end station of the tank feeding conveying mechanism 200 and performs lifting and lowering movements. The group docking assembly 310 includes a first lifting mechanism 311, a carrier plate 312, a first suction unit 313 and a rotating mechanism 314. The upper frame 130 is connected to two downwardly extending vertical plates 131, and the two vertical plates 131 are connected by a horizontal plate 132. The horizontal plate 132 is provided with a first guide sleeve 1321. The first lifting mechanism 311 is a linear cylinder installed on the horizontal plate 132. The carrier plate 312 is provided with a first guide rod 3121 that vertically slides with the first guide sleeve 1321. The piston rod of the linear cylinder is connected to the carrier plate 312 to realize the first lifting mechanism 311 driving the carrier plate 312 to rise and fall. The first suction unit 313 is rotatably mounted on the carrier plate 312. The first suction unit 313 includes a rotating bracket 3131, a first suction cup 3132, and a limiting plate 3133 that rotates synchronously with the rotating bracket 3131. The first suction cup 3132 is mounted on the rotating bracket 3131. The multiple first suction cups 3132 correspond one-to-one to the multiple positioning bosses 211 in a single positioning unit 210. The positioning unit 210 in this embodiment includes two rows of positioning bosses 211. The corresponding first suction unit 313 includes two rows of first suction cups 3132. The limiting plate 3133 is provided with two rows of limiting holes 31331 that correspond one-to-one to the first suction cups 3132. After the first suction cup 3132 absorbs the packaging can 001, the packaging can 001 passes through the limiting holes 31331, and the rotating mechanism 314 The rotating motor is installed on the carrier plate 312, and the rotating bracket 3131 is rotatably installed on the carrier plate 312. The rotating motor drives the rotating bracket 3131 to rotate, so that the first suction cup 3132 can be flipped up and down, and then the adsorbed packaging can 001 can be flipped to an upright state. Such a design can make the inner bottom wall of the packaging can 001 the adsorption part of the grouping conveying component 320, thereby facilitating the adsorption of the grouping conveying component 320 and improving the adsorption reliability of the grouping conveying component 320. At the same time, the packaging can 001 is in an upright state, which is also convenient for later filling. The design of the limit plate 3133 ensures that the packaging can 001 remains in an upright state after being flipped, avoiding the packaging can 001 from tilting during the flipping process. It can be seen that the structure and control program of the group connection component 310 are relatively simple.

[0046] It should be noted that, whenever the grouping docking assembly 310 sucks away the packaging cans 001 on a group of positioning units 210, the first mounting plate 230 slides forward a certain distance so that the packaging cans 001 of a group of positioning units 210 are just located below the grouping docking assembly 310, so that the next time the grouping docking assembly 310 descends to suck up the packaging cans 001 on a group of positioning units 210, it can be seen that by controlling the feeding distance of the first mounting plate 230, the grouping docking assembly 310 can absorb the packaging cans 001 only by lifting and lowering, without the need for the grouping docking assembly 310 to move horizontally, thereby eliminating the translation structure that drives the grouping docking assembly 310 to move horizontally, thereby simplifying the destacking equipment and reducing manufacturing costs.

[0047] In addition, if Figure 7As shown, the group transport component 320 in this embodiment performs lifting and translational movements between the group docking component 310 and the can delivery conveying mechanism 400. The group transport component 320 includes a second suction unit and a second driving mechanism. The second suction unit includes a third mounting plate 321 and two rows of second suction cups 322 mounted on the bottom surface of the third mounting plate 321. The two rows of second suction cups 322 correspond one-to-one to the positioning bosses 211 in the single positioning unit 210. The second suction unit absorbs a row of packaging cans on the group docking component 310 each time. The second driving mechanism includes a second supporting guide rail 323, a second synchronous belt 324, a second mounting plate 325, a second translation unit, and a second lifting unit 326 mounted on the second mounting plate 325. The second supporting guide rail 323 is parallel to the first supporting guide rail 270 and is located above the first supporting guide rail 270. The two second supporting guide rails 323 are mounted on the upper frame 130. The second mounting plate 325 is slidably mounted on the second supporting guide rail 323. The second translation unit includes a driving motor 327, a second main pulley 328, a second auxiliary pulley Pull 329, the driving motor 327 is installed on the upper frame 130 and is connected to the second main pulley 328, the second secondary pulley 329 is rotatably installed on the upper frame 130, the second synchronous belt 324 is wrapped around the second main pulley 328 and the second secondary pulley 329, and the second synchronous belt 324 is connected to the second mounting plate 325. The second synchronous belt 324 can be driven by the driving motor 327 to move to drive the second mounting plate 325 to slide and translate on the second support guide rail 323 between the group docking assembly 310 and the can delivery conveying mechanism 400. The second lifting unit 326 is a cylinder mounted on the second mounting plate 325, and the piston rod of the cylinder is connected to the third mounting plate 321. The third mounting plate 321 is provided with a second guide rod 3211 extending vertically upward. The second guide rod 3211 is vertically slidably matched with the second guide sleeve on the second mounting plate 325, and the piston rod of the cylinder can drive the third mounting plate 321 to rise and fall relative to the second mounting plate 325, so as to drive the second suction unit to rise and fall; in addition, since the distribution and quantity of each column of packaging cans 001 are different, the second suction unit is designed to only suck up one column of packaging cans on the group docking assembly 310 at a time. It is only necessary to control the second suction unit to move to the top of the group docking assembly 310 and control the adsorption of a column of second suction cups 322 corresponding to the packaging cans 001 to be sucked, and the control program is relatively simple; in addition, it can also enable the packaging cans 001 to be transported in a single column on the can discharge conveying mechanism 400, thereby matching the existing filling mechanism and improving the filling efficiency.

[0048] Finally, the can delivery conveying mechanism 400 in this embodiment includes a can delivery conveyor belt (not shown in the figure), a support member 410, a plurality of mold boxes 420 for accommodating packaging cans, a front can blocking assembly and a rear can blocking assembly, wherein the plurality of mold boxes 420 are arranged in a single row and slidably mounted on the can delivery conveyor belt, the support member 410 supports the can delivery conveyor belt, the front can blocking assembly and the rear can blocking assembly are both mounted on the support member 410, with the conveying direction of the can delivery conveyor belt as the front side, the front can blocking assembly is located in front of the rear can blocking assembly, the front can blocking assembly includes a left stopper 430 and a right stopper 440 provided on both sides of the support member 410, a left cylinder (not shown in the figure) for driving the left stopper 430 to move close to or away from the support member 410, and a right cylinder (not shown in the figure) for driving the right stopper 440 to move close to or away from the support member 410, wherein when the left cylinder drives the left stopper 430 close to the support After the can-discharging mechanism 410 is in contact with the left side 430, the left stopper 430 will stop the mold box 420 from moving forward. When the right cylinder drives the right stopper 440 to approach the support member 410, the right stopper 440 will stop the mold box 420 from moving forward. The distance between the left stopper 430 and the right stopper 440 in the conveying direction of the can-discharging conveyor belt is the offset distance between the two adjacent rows of positioning bosses 211. In this embodiment, the right stopper 440 is located in front of the left stopper 430, and the rear can-blocking assembly includes a rear splint 450 and a rear cylinder (not shown in the figure) for driving the rear splint 450 to move close to or away from the support member 410. The rear splint 450 is arranged on one side of the support member 410. After the rear cylinder drives the rear splint 450 to approach the support member 410, the rear splint 450 is against the mold box 420 to stop the mold box 420 from moving forward, so that the number of mold boxes 420 between the front can-blocking assembly and the rear can-blocking assembly is the same as the number of packaging cans sucked by the grouping and handling assembly 320.That is, the number of the first row of positioning bosses 211 in the positioning unit 210 in this embodiment is 8, and the number of the second row of positioning bosses 211 is 9. Therefore, when the left cylinder drives the left stopper 430 to approach the support 410 and the rear cylinder drives the rear splint 450 to approach the support 410, the number of mold boxes 420 between the left stopper 430 and the rear splint 450 is 8. At this time, the number between the front can blocking assembly and the rear can blocking assembly is the same as the number of the first row of positioning bosses 211. When all 8 packaging cans in the first row are placed in the 8 mold boxes 420, the left cylinder drives the left stopper 430 to move away from the support 410. At this time, the mold boxes 420 containing packaging cans 001 are The mold box 420 continues to be conveyed forward, and when the eight mold boxes 420 are located in front of the right stop block 440, the rear cylinder drives the rear splint 450 away from the support 410, so that the mold box 420 continues to be fed in, and the right cylinder drives the right stop block 440 close to the support 410 to block the frontmost mold box 420 from being fed in. Subsequently, the rear cylinder drives the rear splint 450 close to the support 410. At this time, the number of mold boxes 420 between the right stop block 440 and the rear splint 450 is 9. At this time, the number between the front can blocking assembly and the rear can blocking assembly is the same as the number of the second column positioning bosses 211, so that the 9 packaging cans 001 in the second column can be placed in the 9 mold boxes 420 respectively.

[0049] In order to facilitate those skilled in the art to understand the working process of the transport and conveying device in this embodiment, the working process of the transport and conveying device will be described in detail below:

[0050] The first mounting plate 230 carrying the packaging can 001 slides to the output end station of the can feeding conveying mechanism under the driving action of the first driving mechanism, and then the first lifting mechanism 311 of the grouping connecting assembly 310 drives the loading plate 312 to move downward, so that the first suction unit 313 can descend and suck the packaging can 001 on a group of positioning units 210, and then the first lifting mechanism 311 drives the loading plate 312 to rise and reset to make the packaging can 001 disengage from the positioning boss 211. After resetting, the rotating mechanism 314 drives the first suction unit 313 to rotate to flip the packaging can 001 to an upright state, and then drives the second suction unit 313 to rotate and turn the packaging can 001 to an upright state through the second driving mechanism. The taking unit descends to allow a row of second suction cups 322 to adsorb the inner bottom wall of the packaging can 001, and then the second driving mechanism drives the second suction unit to rise and reset to make the packaging can 001 escape from the limiting hole 31331. At this time, the rotating mechanism 314 drives the first suction unit 313 to rotate and reset to facilitate the next adsorption of the packaging can 001. Then the second driving mechanism drives the second suction unit to move horizontally to above the input end station of the can discharge conveyor belt, and then the second driving mechanism drives the second suction unit to descend and place the packaging can 001 on the corresponding mold box 420. Finally, the can discharge conveyor belt drives the mold box 420 containing the packaging can 001 forward for filling.

[0051] It should be noted that each time the grouping transport component 320 absorbs a row of upright packaging cans 001 and transports the packaging cans 001 to place them on the can outlet conveying mechanism 400, the grouping transport component 320 returns to continue to transport the remaining packaging cans 001 on the grouping docking component 310 and place them on the can outlet conveying mechanism 400 until all the packaging cans 001 on the grouping docking component 310 are transported. Next, the grouping docking component 310 descends to absorb the next group of positioning units 210 on the can inlet conveying mechanism 200 and transports and places them on the can outlet conveying mechanism 400 through the grouping transport component 320 until all the packaging cans 001 on the first mounting plate 230 are transported.

[0052] In summary, in the entire transporting and conveying process of the handling and conveying device of this embodiment, the packaging cans 001 are kept spaced apart, thereby preventing adjacent packaging cans 001 from contacting and squeezing each other, and further avoiding appearance defects of the packaging cans 001.

[0053] It is understandable that in other embodiments of the present invention, the positioning boss may also be a cylindrical boss, and the outer diameter of the cylindrical boss is smaller than the inner diameter of the packaging can.

[0054] Example 2

[0055] Compared with Example 1, the difference of this embodiment is that the conveying direction of the can inlet conveying mechanism is parallel to the conveying direction of the can outlet conveying mechanism, that is, the extension direction of the length of the first support guide rail is parallel to the conveying direction of the can outlet conveyor belt, and multiple groups of positioning units are arranged along the conveying direction perpendicular to the can inlet conveying mechanism, that is, they are arranged in the manner of Example 1. At this time, after the first mounting plate slides to the output end station of the can inlet conveying mechanism, it remains in a fixed position for a period of time until the group docking assembly transports the packaging cans on the first mounting plate. The group docking assembly performs a lifting and translational movement above the output end station of the can inlet conveying mechanism. The structure for driving the lifting and translational movement of the group docking assembly refers to the setting of the group transporting assembly and will not be described in detail here. The first suction unit can be located above the positioning unit at different positions through the translation of the group docking assembly to facilitate the first suction unit to descend and absorb the packaging cans, and the structure of the group transporting assembly is the same as that of Example 1. The group transporting assembly performs a lifting and translational movement between the group docking assembly and the can outlet conveying mechanism to transport the packaging cans on the group docking assembly to the can outlet conveying mechanism.

[0056] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
