Technical Field

[0001] The utility model belongs to the field of box tray processing equipment, and particularly relates to a novel box tray opening device. Background Art

[0002] In the field of pharmaceutical production and processing, products such as medicine bottles are generally transported or transferred in plastic box trays. After being folded, the plastic box trays are generally fixed by hanging with rubber bands. After taking out the products in the plastic box trays, it is necessary to remove and unfold the rubber bands on the box trays, so as to facilitate the subsequent centralized recycling and treatment of the plastic box trays. The existing box opening operations are all manually operated by workers, which is time-consuming, laborious and inefficient. Content of the Utility Model

[0003] In order to solve the deficiencies of the prior art, the utility model aims to provide a novel box tray opening device, which can quickly remove the rubber bands on the plastic box trays, and flatten and centrally collect the box trays, thereby significantly improving the box opening efficiency of the box trays.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A novel box tray opening device includes a frame. A conveyor for conveying box trays is horizontally installed on the frame. A box supporting mechanism and a hooking mechanism are installed on the frame at the tail of the conveyor. The box supporting mechanism is used for pushing the box trays on the side where the rubber bands are fixed outwards; the hooking mechanism is used for untying the rubber bands on the box trays; a box taking mechanism and a storage mechanism are also provided on the frame. The storage mechanism is used for stacking and storing the opened box trays; the box taking mechanism is installed between the storage mechanism and the conveyor, and is used for conveying the unfolded box trays on the conveyor to the storage mechanism.

[0006] Preferably, the box trays are placed with the openings facing downwards on the conveyor for conveying, and the sides where the rubber bands on the box trays are fixed are located outside both sides of the conveyor.

[0007] Preferably, the box supporting mechanism includes two sets of box supporting components symmetrically arranged on both sides of the conveyor; each box supporting component includes a first horizontal driving component and a first vertical driving component. The first horizontal driving component is horizontally installed on the frame perpendicular to the length direction of the conveyor. The first vertical driving component is vertically installed at the moving end of the first horizontal driving component. A top block is installed at the moving end above the first vertical driving component. The top block extends from below the box tray into the box tray and pushes the side where the rubber bands of the box tray are fixed outwards.

[0008] Preferably, the hooking mechanism includes two sets of hooking components symmetrically arranged on both sides of the conveyor. Each hooking component includes a second horizontal driving component, a rotating component, and an L-shaped hook. The second horizontal driving component is installed on the frame parallel to the conveyor. The rotating component is installed at the operating end of the second horizontal driving component. The hook is fixed at the operating end of the rotating component and is used to hook the rubber band on the box support.

[0009] Preferably, the box supporting mechanism further includes two sets of high-pressure nozzles symmetrically installed under the conveyor. The two high-pressure nozzles are respectively arranged towards two inner walls adjacent to the side where the rubber band is fixed on the box support, and the high-pressure nozzles are connected to an external air source.

[0010] Preferably, the box taking mechanism includes a negative pressure suction cup, a second vertical driving component, and a third horizontal driving component. The third horizontal driving component is horizontally installed on the frame above the material storage mechanism and the conveyor. The second vertical driving component is vertically installed at the operating end of the third horizontal driving component. The negative pressure suction cup is horizontally installed at the operating end below the second vertical driving component.

[0011] Preferably, the material storage mechanism includes a storage rack arranged on the frame, and the storage rack is provided with a material slot for placing the opened box support.

[0012] Preferably, the storage rack is horizontally movably arranged on the frame; the material storage mechanism further includes a fourth horizontal driving component horizontally installed on the frame, and the operating end of the fourth horizontal driving component is connected to the storage rack and is used to push the storage rack towards the material discharge opening on the side of the frame.

[0013] Preferably, conveying limit plates are arranged along the length direction on both sides of the conveyor.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. When the first horizontal cylinder of the present utility model extends, it drives the first vertical cylinder and the top block to approach the conveyor and move below the opening of the box support. Then, the first vertical cylinder extends upward, so that the top block extends from below the box support into the interior of the box support. After that, the first horizontal cylinder contracts a certain distance, so that the top block pushes against the inner wall of the side where the rubber band is fixed and moves outward, thereby pushing the side where the rubber band is fixed outward to facilitate the hook of the hooking mechanism to hook the rubber band. After the rubber band is removed, the first horizontal cylinder continues to contract, so that the entire side where the rubber band is fixed can be pushed open.

[0016] 2. The box support assembly opens the rubber band fixing side of the box tray outward, which is not only convenient for the hook-pull mechanism to grab the rubber band, but also can fix the box tray on the conveyor. When taking out the rubber band on the box tray, the second horizontal cylinder drives the right-angle rotating cylinder and the hook to move toward the box tray, and then the right-angle rotating cylinder drives the hook to rotate downward 90 degrees, so that the hook is hooked on the rubber band side of the box tray, and then the second horizontal cylinder contracts, and the hook hangs on the rubber band to stretch it out so that it is out of the slot on the box tray, and then the right-angle rotating cylinder drives the hook to rotate in the opposite direction to reset, and then the rubber band can be detached from the hook, so that the rubber band on the box tray can be removed.

[0017] 3. When the hook-pull mechanism removes the rubber band on the box tray, the high-pressure gas ejected from the high-pressure gas nozzle can blow the corresponding box tray side wall outward, thereby flattening the corresponding box tray side wall, which is convenient for subsequent box tray stacking and storage.

[0018] 4. Through the cooperation of the second vertical drive assembly and the third horizontal drive assembly, the negative pressure suction cup grabs the unfolded box tray on the conveyor belt and moves it to the top of the storage rack of the storage mechanism. The second vertical drive assembly drives the negative pressure suction cup downward to place the unfolded box tray on the storage rack. If the box trays on the storage rack are stacked loosely, the second vertical drive assembly can be used to move downward a certain distance to compact the stacked box trays.

[0019] 5. After the fourth horizontal cylinder delivers the stacked boxes and trays on the storage rack to the unloading port, the strapping mechanism can be used to bundle the unfolded boxes and trays, making it easier for the subsequent recycling of the boxes and trays.

[0025] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0026] like Figures 1-5As shown in the figure, the present utility model provides a new type of box tray opening device, which includes a frame 1. A conveyor 2 for conveying the box tray 5 is horizontally installed on the frame 1. Conveyor limit plates 21 are provided on both sides of the conveyor 2 along its length direction. Under the limiting action of the conveyor limit plates 21, the box tray 5 is placed on the conveyor 2 with its opening facing downwards. And the body width of the conveyor 2 is smaller than the width of the box tray 5, so that the two rubber band fixing sides on the box tray 5 are located outside both sides of the conveyor 2.

[0027] A box supporting mechanism and a hook pulling mechanism are installed on the frame 1 at the tail of the conveyor 2. The box supporting mechanism is used to push the box tray 5 with the rubber band fixing side outwards. Specifically, the box supporting mechanism includes two groups of box supporting components 3 symmetrically arranged on both sides of the conveyor 2. Each group of box supporting components 3 includes a first horizontal driving component and a first vertical driving component. The first horizontal driving component and the first vertical driving component are respectively a first horizontal cylinder 31 and a first vertical cylinder 32. The first horizontal cylinder 31 is horizontally installed on the frame 1 perpendicular to the length direction of the conveyor 2. The first vertical cylinder 32 is vertically installed on the piston rod of the first horizontal cylinder 31. A top block 33 is fixedly installed at the upper end of the piston cylinder of the first vertical cylinder 32.

[0028] After the first horizontal cylinder 31 extends to drive the first vertical cylinder 32 and the top block 33 to approach the conveyor 2 and move below the opening of the box tray 5, the first vertical cylinder 32 extends upwards, so that the top block 33 extends from below the box tray 5 into the box tray 5. Then the first horizontal cylinder 31 contracts a certain distance, so that the top block 33 pushes against the inner wall of the rubber band fixing side and moves outwards, thereby pushing the rubber band fixing side outwards to facilitate the hook 43 of the hook pulling mechanism to hook the rubber band 51. After the rubber band 51 is removed, the first horizontal cylinder 31 continues to contract, so that the entire rubber band fixing side can be pushed open.

[0029] The hook pulling mechanism is used to untie the rubber band 51 on the box tray 5. Specifically, the hook pulling mechanism includes two groups of hook pulling components 4 symmetrically arranged on both sides of the conveyor 2. Each hook pulling component 4 includes a second horizontal driving component, a rotating component and an L-shaped hook 43. The second horizontal driving component and the rotating component are respectively a second horizontal cylinder 41 and a right-angle rotating cylinder 42. The second horizontal cylinder 41 is installed on the frame 1 parallel to the conveyor 2 and facing the first horizontal cylinder 31 side. The right-angle rotating cylinder 42 is installed on the piston rod of the second horizontal cylinder 41. The hook 43 is fixed at the action end of the right-angle rotating cylinder 42, and the hook 43 is used to hook the rubber band 51 on the box tray 5.

[0030] The box-supporting component 3 spreads the rubber-band fixed side of the box tray 5 outward, which not only facilitates the hooking mechanism to grab the rubber band 51, but also can fix the box tray 5 on the conveyor 2. When grabbing the rubber band 51 on the box tray 5, the second horizontal cylinder 41 drives the right-angle rotating cylinder 42 and the hook 43 to horizontally move toward the box tray 5 side. Then, the right-angle rotating cylinder 42 drives the hook 43 to rotate downward by 90 degrees, so that the hook 43 hooks the rubber band 51 downward from the gap between the box tray 5 and the rubber band 51. After that, the second horizontal cylinder 41 drives the hook to contract and reset, and the hook 43 hooks the rubber band 51 and stretches it outward. At this time, the rubber band 51 can be separated from the card slot 50 on the box tray 5, and the right-angle rotating cylinder 42 drives the hook 43 to rotate in the reverse direction and reset, so that the rubber band 51 on the box tray 5 can be easily removed.

[0031] The box-supporting mechanism further includes two groups of high-pressure nozzles 34 symmetrically installed under the conveyor 2. The two high-pressure nozzles 34 are respectively arranged toward two inner walls adjacent to the rubber-band fixed side of the box tray 5, and the high-pressure nozzles 34 are connected to an external air source. In specific implementation, the conveyor 2 is a belt conveyor 2 with two parallel conveyor belts. The high-pressure nozzles 34 are installed between the two conveyor belts.

[0032] After the hooking mechanism removes the rubber band 51 on the box tray 5, the high-pressure gas ejected from the high-pressure nozzles 34 can blow the side wall of the corresponding box tray 5 outward, so as to flatten the side wall of the corresponding box tray 5, which is convenient for subsequent stacking and storing of the box tray 5.

[0033] The frame 1 is also provided with a box-taking mechanism and a material-storing mechanism. The material-storing mechanism is used to store the disassembled box trays 5. The box-taking mechanism is installed between the material-storing mechanism and the conveyor 2, and is used to convey the unfolded box trays 5 on the conveyor 2 to the material-storing mechanism. The box-taking mechanism includes a negative-pressure suction cup 63, a second vertical driving component 62 and a third horizontal driving component 61. Both the second vertical driving component 62 and the third horizontal driving component 61 adopt the synchronous belt driving modules commonly used in the prior art. The third horizontal driving component 61 is horizontally installed on the frame 1 above the material-storing mechanism and the conveyor 2. The second vertical driving component 62 is vertically installed on the moving end of the third horizontal driving component 61. The negative-pressure suction cup 63 is horizontally installed on the moving end below the second vertical driving component 62. The negative-pressure suction cup 63 is connected to an external negative-pressure source.

[0034] Through the coordinated cooperation of the second vertical driving component 62 and the third horizontal driving component 61, the negative-pressure suction cup 63 grabs the unfolded box tray 5 on the conveyor belt and moves it above the storage rack 7 of the material-storing mechanism. The second vertical driving component 62 is used to drive the negative-pressure suction cup 63 to move downward to place the unfolded box tray 5 on the storage rack 7. If the stacked box trays 5 on the storage rack 7 are relatively fluffy, the second vertical driving component 62 can be used to move downward a certain distance to press down the stacked box trays 5.

[0035] The stock storage mechanism includes a storage rack 7 horizontally movably arranged on the rack 1, and a material slot for placing the opened box tray 5 is provided on the storage rack 7. The stock storage mechanism further includes a fourth horizontal driving component horizontally installed on the rack 1, and the fourth horizontal driving component is a fourth horizontal cylinder 71. The piston rod of the fourth horizontal cylinder 71 is connected to the storage rack 7 and is used to push the storage rack 7 towards the blanking port 11 on the side of the rack 1. A bundling mechanism 8 is installed at the blanking port 11 of the rack 1, and the bundling mechanism 8 is used to bundle and pack the box trays 5 on the storage rack 7. The bundling mechanism 8 adopts a tie bundling device commonly used in the prior art.

[0036] After the fourth horizontal cylinder 71 sends the palletized box trays 5 on the storage rack 7 to the blanking port 11, through the action of the bundling mechanism 8, the unfolded box trays 5 can be bundled, which is more convenient for the subsequent recycling of the box trays 5.

[0037] When using the present utility model, after the box tray 5 with the opening facing down is sent to the tail end of the conveyor 2, the box supporting mechanism acts, so that the top block 33 extends from below the box tray 5 into the interior of the box tray 5 and pushes the fixed side of the rubber band outwards; the hook pulling mechanism acts to hook one side of the rubber band 51 from the gap between the box tray 5 and the rubber band 51 and pulls it outwards, so that the rubber band 51 is separated from the card slot 50 on the box tray 5, and then the rubber band 51 on the box tray 5 can be removed; the first horizontal cylinder 31 drives the top block 33 to continue to contract, and cooperates with the high-pressure gas ejected by the high-pressure gas nozzle 34, so that the side walls around the box tray 5 can be unfolded outwards; then through the coordinated cooperation of the second vertical driving component 62 and the third horizontal driving component 61, the negative pressure suction cup 63 grabs the unfolded box tray 5 on the conveyor belt and places it on the storage rack 7; after the box trays 5 on the storage rack 7 are stacked to a certain height, the fourth horizontal cylinder 71 sends the storage rack 7 to the blanking port 11, and through the action of the bundling mechanism 8, the unfolded box trays 5 can be bundled, which is more convenient for the subsequent recycling of the box trays 5.
