Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to an unpacking device and unpacking machine. Background Technology

[0002] Carton openers automatically unfold folded cardboard. During operation, the cardboard is first opened from its folded position. Then, the short sides of the carton are folded inwards sequentially, followed by the long sides. However, in practice, when folding the short sides inwards, the long sides are not fully opened, causing interference between the short and long sides. This prevents the short sides from being folded inwards completely, or prevents them from being folded inwards along with the long sides, affecting the sealing of the bottom of the carton. Therefore, a device that improves the unfolding and forming effect of folded cardboard is urgently needed. Utility Model Content

[0003] The purpose of this utility model is to provide a box-opening device and box-opening machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] An unpacking device includes: a frame with a feed inlet on one side; an unpacking mechanism having a transfer plate that can move closer to or further away from the feed inlet, a first suction cup on the transfer plate, and a rotatable folding plate on one side of the transfer plate that can move closer to or further away from the feed inlet; and a packing mechanism having a first packing member and a second packing member that can move up and down, the first packing member and the second packing member being able to move closer to or further away from each other, wherein after the transfer plate moves in a direction away from the feed inlet, the first packing member and the second packing member move to a position between the transfer plate and the feed inlet.

[0006] This technical solution has at least the following beneficial effects: The folded cardboard to be opened is located at the feed inlet of the frame. The transfer plate in the box opening mechanism moves closer to the feed inlet. At this time, the folding plate rotates to a state away from the feed inlet. The first suction cup on the transfer plate adsorbs the folded cardboard and pulls it away from the feed inlet. The folding position on the folded cardboard is exactly between the transfer plate and the folding plate. When the folded cardboard on the transfer plate rotates towards the feed inlet, it opens along the folding position, forming the box structure. Then, the first and second box support components move between the transfer plate and the feed inlet, and then move away from each other, opening the long sides of the bottom of the box outward. This can further assist the forming of the carton and ensure that the subsequent process of folding the short sides of the bottom of the box inward is carried out smoothly. This effectively improves the quality of the carton forming and the smoothness of the inward folding and closing of the bottom of the carton, reducing the defect rate of opening the box.

[0007] As a further improvement to the above technical solution, the box-supporting mechanism includes a lifting drive component, a movable gripper finger, and a connecting plate. The lifting drive component is connected to the frame, and the movable gripper finger is connected to the lifting drive component. The lifting drive component can drive the movable gripper finger to move up and down. The movable gripper finger is driven to connect two connecting plates. The movable gripper finger can drive the two connecting plates to move closer to each other or further away. The first box-supporting component and the second box-supporting component are respectively provided on the two connecting plates.

[0008] As a further improvement to the above technical solution, connecting arms are respectively connected to the two connecting plates, and the two connecting arms extend in a direction perpendicular to the movement of the transfer plate. The first support box and the second support box are arranged in multiple ways along the length direction of the two connecting arms.

[0009] As a further improvement to the above technical solution, the two connecting arms can move and be positioned on the two connecting plates in directions that are closer to or further away from each other.

[0010] As a further improvement to the above technical solution, the sides of the first support box and the second support box that are far apart from each other extend downwards at an angle in the direction of mutual distance.

[0011] As a further improvement to the above technical solution, a feeding rack is provided on the bottom side of the frame at the feed inlet, the feeding rack extends upward at an angle away from the feed inlet, and a material stop is provided on the top side of the feeding rack at the feed inlet.

[0012] As a further improvement to the above technical solution, a pressure plate is slidably connected to the feeding rack, and the pressure plate can slide closer to or further away from the feeding port.

[0013] As a further improvement to the above technical solution, a second suction cup is provided on the folding plate.

[0014] As a further improvement to the above technical solution, a motor is provided on the top side of the transfer plate, and the motor drives the folding plate.

[0015] A box-opening machine, comprising the box-opening device described above.

[0016] This technical solution has at least the following beneficial effects: In this carton opener, since the carton opening device can open the long sides of the bottom of the carton outward when opening and forming the folded cardboard, it can not only further assist the forming of the carton, but also ensure that the carton opener can smoothly carry out the inward folding process of the short sides of the bottom of the carton. This effectively improves the quality of carton forming, improves the smoothness of the inward folding and closing of the bottom edge of the carton, and reduces the defect rate of opening the carton.

[0028] Reference Figures 1 to 3 A box-opening device includes a frame 100, a box-opening mechanism 200, and a box-supporting mechanism 300. The frame 100 has a feed inlet on one side. The box-opening mechanism 200 has a transfer plate 210 that can move closer to or further away from the feed inlet. A first suction cup is mounted on the transfer plate 210. The first suction cup is connected to a negative pressure pump via a pipe, which generates negative pressure suction. A folding plate 220 that can rotate to move closer to or further away from the feed inlet is mounted on one side of the transfer plate 210. The box-supporting mechanism 300 has a first box-supporting member 310 and a second box-supporting member 320 that can move up and down. The first box-supporting member 310 and the second box-supporting member 320 can move closer to or further away from each other. After the transfer plate 210 moves away from the feed inlet, the first box-supporting member 310 and the second box-supporting member 320 move to a position between the transfer plate 210 and the feed inlet.

[0029] As described above, the folded cardboard to be opened is located at the feed inlet of the frame 100. The transfer plate 210 in the opening mechanism 200 moves closer to the feed inlet. At this time, the folding plate 220 rotates to a position away from the feed inlet. The first suction cup on the transfer plate 210 picks up the folded cardboard and pulls it away from the feed inlet. The folded position on the cardboard is exactly between the transfer plate 210 and the folding plate 220. When the folded cardboard on the transfer plate 210 rotates towards the feed inlet... The first support piece 310 and the second support piece 320 are moved to the space between the transfer plate 210 and the feed inlet, and then move away from each other to open the long sides of the bottom of the box outward. This not only further assists in the forming of the carton, but also ensures that the subsequent inward folding of the short sides of the bottom of the box can be carried out smoothly. This effectively improves the quality of the carton forming and the smoothness of the inward folding and closing of the bottom of the carton, and reduces the defect rate of opening the box.

[0030] The support mechanism 300 includes a drive source that can move the first support member 310 and the second support member 320 up and down, as well as a drive source that moves them closer or further apart. Specifically, the support mechanism 300 includes a lifting drive member 330, a movable gripper finger 340, and a connecting plate 350. The lifting drive member 330 is connected to the frame 100, and the movable gripper finger 340 is connected to the lifting drive member 330. The lifting drive member 330 can move the movable gripper finger 340 up and down. The lifting drive member 330 can be driven by an electric screw, a cylinder, or a hydraulic cylinder. The movable gripper finger 340 drives two connecting plates 350, and the movable gripper finger 340 can move the two connecting plates 350 closer or further apart. The first support member 310 and the second support member 320 are respectively provided on the two connecting plates 350. The movable gripper finger 340 can be an electric gripper finger or a pneumatic gripper finger.

[0031] In this box-supporting mechanism 300, when the folded cardboard is moved in and opened, the lifting drive 330 drives the first box-supporting component 310 and the second box-supporting component 320 to move down to the bottom of the stroke, so that the first box-supporting component 310 and the second box-supporting component 320 will not interfere with the movement of the folded cardboard. When the carton is opened, the lifting drive drives the first box-supporting component 310 and the second box-supporting component 320 to move up to the top of the stroke, so that the first box-supporting component 310 and the second box-supporting component 320 enter the inside of the carton. Then, the first box-supporting component 310 and the second box-supporting component 320 move in a direction away from each other, opening the two long sides of the bottom of the carton outward, thereby ensuring that the two short sides of the bottom of the carton can be folded inward smoothly, improving the quality of the carton opening and forming.

[0032] In the above embodiments, there may be only one first box support 310 and one second box support 320. In order to increase the area of ​​the first box support 310 and the second box support 320 acting on the bottom side of the carton, in this embodiment, each of the two connecting plates 350 is connected to a connecting arm 360. The two connecting arms 360 extend in a direction perpendicular to the movement of the transfer plate 210. Multiple first box support 310 and second box support 320 are arranged along the length direction of the two connecting arms 360. In use, the two connecting arms 360 are parallel to the two long sides of the bottom of the carton. Multiple first support components 310 and multiple second support components 320 are located on the two connecting arms 360 respectively. When moving upward, they can enter the carton at the same time. Then, the multiple first support components 310 and multiple second support components 320 are inserted into the carton. At this time, the multiple first support components 310 and multiple second support components 320 abut against the two long sides of the carton respectively, which can increase the range of force applied to the long sides, thereby stably pushing the two sides of the carton open to both sides.

[0033] When the size of the carton to be opened changes, the relative positions of the two connecting arms 360 entering the carton also need to be adjusted. Therefore, in this embodiment, the two connecting arms 360 can move and be positioned on the two connecting plates 350 in directions that are closer or further apart. When the size of the carton decreases, the two connecting arms 360 can move closer to each other to adapt to the size of the carton; conversely, when the size of the carton increases, the two connecting arms 360 can move further apart, thus improving the overall versatility. In practical applications, there are various ways to adjust and position the connecting arms 360 on the connecting plate 350. For example, a slot is provided on the connecting plate 350, extending in a direction perpendicular to the feed inlet. A screw is passed through the connecting plate 350, and a nut is connected after the screw passes through the slot. When the position of the connecting arm 360 needs to be adjusted, the nut can be loosened, and the connecting arm 360 can be adjusted along the length of the slot. After adjustment, the screw is tightened by the nut, thereby pressing and fixing the connecting arm 360 onto the connecting plate 350.

[0034] To more accurately insert the first support member 310 and the second support member 320 into the carton, in this embodiment, the sides of the first support member 310 and the second support member 320 that are far apart from each other extend downwards at an angle in the direction of mutual distance. The angled arrangement of the sides of the first support member 310 and the second support member 320 facilitates their insertion between the two long sides of the bottom of the carton. Once the two long sides of the bottom of the carton abut against the angled sides of the first support member 310 and the second support member 320, they can be directly opened to both sides along the guide of the angled sides.

[0035] The cardboard to be opened can be fed into the feed port by an external device. In this embodiment, a feeding structure can be directly set next to the feed port. Specifically, the frame 100 is provided with a feeding rack 110 at the bottom side of the feed port. The feeding rack 110 extends upward at an angle away from the feed port. The feeding rack 110 is provided with a baffle 120 at the top side of the feed port. Folded cardboard pieces to be unpacked are arranged on the feeding rack 110, and the baffle 120 located on the top side of the feeding rack 110 blocks the folded cardboard pieces from falling directly out of the feeding port. Then, the first suction cup on the transfer plate 210 pulls the folded cardboard pieces from the feeding port, so that the side of the folded cardboard pieces passes over the baffle 120 located on the top side of the feeding rack 110. Subsequent folded cardboard pieces can then move along the inclined feeding rack 110 to the feeding port to replenish the remaining pieces under the action of gravity. This achieves automatic feeding at the feeding port.

[0036] To ensure continuous feeding of the folded cardboard into the feed inlet, in this embodiment, a pressure plate 111 is slidably connected to the feed rack 110. The pressure plate 111 can slide closer to or further away from the feed inlet. The pressure plate 111 itself has gravity, and under the action of gravity, it slides down the feed rack 110 towards the feed inlet, pushing the folded cardboard towards the feed inlet, thereby achieving automatic feeding of the feed inlet.

[0037] To improve the stability of transferring and folding the folded cardboard, a second suction cup is provided on the folding plate 220 in this embodiment. When the folding plate 220 approaches the folded cardboard, the second suction cup also approaches the folded cardboard to pick it up and fix it in place, thereby increasing the force coverage area when transferring the folded cardboard and ensuring the stability of removing the folded cardboard.

[0038] Naturally, the unpacking mechanism 200 includes a drive source, such as a rotary cylinder, capable of rotating the folding plate 220. In this embodiment, a motor 230 is mounted on the top side of the transfer plate 210, and the motor 230 drives the folding plate 220. The motor 230 provides a rotational driving force to the folding plate 220, causing it to rotate relative to the transfer plate 210, thereby unfolding the folded cardboard.

[0039] In addition, the unpacking mechanism 200 has a drive source that can move the transfer plate 210 closer to or away from the feed port. Specifically, for example, the unpacking mechanism 200 includes an electric screw, cylinder or hydraulic cylinder mounted on the frame 100, which moves the transfer plate 210 closer to or away from the feed port in a linear direction. Alternatively, the unpacking mechanism 200 includes a six-degree-of-freedom robotic arm mounted on the frame 100, which moves the transfer plate 210 closer to the feed port to remove the folded cardboard. After the folded cardboard is formed into a carton, it is directly sent out.

This effectively improves the quality of carton forming, improves the smoothness of the inward folding and closing of the bottom edge of the carton, and reduces the defect rate of opening the carton.
