Description

Automatic opening and closing board placing device for composite carton

Technical Field

The invention relates to a carton opening and closing board placing device, in particular to a composite type automatic carton opening and closing board placing device.

Background

At present, when a manufacturer packages a machined and formed product, an automatic case unpacking machine and an automatic case sealing machine are mostly adopted for processing, when the automatic case unpacking machine is used, a folded carton is opened and bottom-sealed, then the folded carton is conveyed to a packaging station, and an operator loads the product into the carton; after the products are packed, the carton is sent into the automatic carton sealing machine by the operating personnel for sealing, thereby realizing the packing and the encapsulation of the products. Meanwhile, when products of different types and specifications need to be packed by adopting different types of cartons, a manufacturer can correspondingly set a plurality of stations, and each station is respectively provided with a case unpacking machine and a conveying belt, so that each case unpacking machine can respectively convey different types of cartons to corresponding packing stations, and misloading among different stations is avoided.

However, in the actual production process, the packing speed of the operators is far slower than the unpacking speed of the equipment, so that the automatic unpacking machine can be in a stagnation waiting state for a long time, thereby greatly reducing the utilization rate of the unpacking machine and causing the waste of resources. If a single automatic case unpacking machine is used for simultaneously packing various different types of cartons, a separate packing person needs to be independently arranged to put various types of cartons into the automatic case unpacking machine, and the unpacked cartons are distributed, so that the labor cost is increased. On the other hand, because automatic case unpacking machine and automatic case sealer can only encapsulate the carton of appointed specification after the debugging, lead to when the carton size of different specifications exists the difference, still need be by the partial shipment personnel according to the carton size package part in to equipment relocate and debug to the change degree of difficulty to different specification cartons has further been increased.

In addition, the carton baffle still can be used at the vanning in-process to the product, and the appearance of present carton baffle generally is cross or groined type, and forms through seam each other amalgamation by the polylith baffle monomer. The existing method for placing the carton partition plates is divided into two types, wherein when the carton partition plates are made of paper, manufacturers directly place the carton partition plates into the carton after splicing during carton production, so that the carton partition plates are folded into sheets along with the carton and then sent together. When the carton partition plates are made of rigid materials such as plastics and nylon, the carton partition plates cannot be folded together with the carton, so that the carton partition plates need to be transported in batches in the form of the individual partition plates when being sent, and the individual partition plates are spliced by operators each time and then are put into the carton together with products when being boxed. However, the manual on-site board placing mode inevitably prolongs the whole boxing time, so that the boxing efficiency of the production line is reduced, and the economic pursuit of manufacturers cannot be met. On the other hand, with the increasing demand of the automation degree of the current production line, the mode of boxing by replacing the manual work with a machine is more and more common, and the current manufacturers use a mechanical arm to replace the personnel to complete the placement of the product. However, for the carton partition board made of hard material, the operation can not be completed by only a manipulator because the carton partition board needs to be spliced before boxing; the factory needs to correspondingly add a station for manually splicing the carton partition plates, namely, the splicing action of the carton partition plates is completed manually, and then the subsequent plate placing action is completed by the manipulator, so that the full automation of the whole boxing process cannot be realized.

after the top block 14 is separated from the tooth-shaped groove 12, the elastic plate 16 exerts resilience force on the telescopic piece 13, so that the top block 14 can be buckled with the tooth-shaped groove 12 again at the next buckling position; under the cooperation, the extension length of the telescopic piece 13 can be larger than the thickness of the single partition plate, so that after each single partition plate is pulled out, the subsequent single partition plates can be pressed in place under the pushing action, and the single partition plate and the taking-out opening 8 are prevented from being mutually dislocated due to the fact that the single partition plate cannot be translated; meanwhile, through the frictional resistance applied to the driving rod 11 and the matching action of the ejecting block 14, the ejecting block 14 cannot apply pretightening force to the driving rod 11 when the telescopic piece 13 is in a contraction state, so that the clamping stagnation problem caused by overlarge extrusion force when the single partition plate is ejected or extracted is avoided, and the action stability of the single partition plate is improved; in addition, because the telescopic length of the telescopic piece 13 exceeds the moving length of the driving rod 11 and the length of one toothed groove 12 each time, the length of the toothed groove 12 and the moving length of the driving rod 11 each time are not related to each other under the action, and then a manufacturer can increase the length of the toothed groove 12 during design, namely the driving stability and the pressing effect of the driving rod 11 are improved;

C3. the manipulator 3 returns to the high position after grabbing, and then rotates 90 degrees to be above another appointed plate placing groove 7;

C4. the single partition plates are ejected out by an ejection column 9 of the other plate placing groove 7, and meanwhile, the mechanical arm 3 drives the single partition plates to descend to a low position, so that the insertion joints in the middle of the two single partition plates are mutually buckled under extrusion to form the paper box partition plate;

C5. the manipulator 3 returns to the high position and rotates 90 degrees to the top of the carton after the carton partition is buckled, then falls to place the carton partition into the carton, and the carton partition is completely buckled under the extrusion of the bottom of the carton and the manipulator 3 when the manipulator 3 falls in place.

The working principle of the invention is as follows: according to the carton unpacking machine, the carton unpacking machine 1 can drive the carton unpacking machine 1 to unpack cartons with corresponding specifications according to the number of the cartons on different waiting roller ways 28 through optimizing the carton unpacking and conveying structures, and the cartons with different specifications are conveyed in place after unpacking by utilizing the matching of the conveying roller ways 27 and the transverse moving seats 30, so that the cartons with corresponding specifications can be packed at different packing stations, the packing efficiency of operators is improved, and the misloading problem is avoided. Through the optimization to putting the board structure, make it can also adorn the baffle monomer that is in the state of piling up and get and amalgamate to put into the carton with the carton baffle after the amalgamation. Under the cooperation, the carton opening and closing device can be used for opening, placing and sealing a plurality of cartons with different specifications at the same time, and compared with the existing multi-station carton opening and closing device, the carton opening and closing device can effectively reduce the number of the carton opening machines 1 and the carton sealing machines 2, and realizes the effect of full-process automatic operation.

When the sizes of the cartons with different specifications are different, the height of the fixed guide rail 23 and the height of the sliding guide rail 24 can be synchronously adjusted through the matching of the placing rack 20, and the height of the upper limiting plate 26 is adjusted in a matching manner, so that the bottom heights of the cartons after bottom closing can be kept uniform; through the matching arrangement of the fixed guide rail 23 and the upright post 36, the transverse position of the fixed guide rail 23 on the placing rack 20 can be kept unchanged, and one end of different mounted cartons can be limited; under the cooperation, the carton unpacking machine 1 can realize the unpacking of cartons with different sizes only by adjusting the interval between the carton pressing rod and the second conveying belt and the opening interval of the second conveying belt. Similarly, the position of the packaging frame and the third conveying belt in the carton sealing machine 2 is controlled, so that the carton sealing machine 2 can seal cartons with different sizes through adjustment, and the opening and closing stability of the carton sealing machine is ensured.
