Description

Technical Field

[0001] The present application relates to the field of paper box packaging technology, and in particular to a paper box taking and opening mechanism. Background Art

[0002] Paper box packaging has been widely used in many fields such as daily necessities, food, medicine, etc. General paper boxes are usually folded before packaging. When using, each folded paper box needs to be turned from the folded state to a three-dimensional state, that is, "opening the box".

[0003] The existing carton opening machine usually uses a movable adsorption component to absorb the carton and then drive the carton to move, so that the carton gradually opens during the movement. The existing carton used for packaging is usually a rectangular parallelepiped structure, and after the carton is opened, the four side walls of the carton need to be kept in a state of being perpendicular to each other for subsequent packaging. Therefore, a material taking and carton opening mechanism is needed, which can keep the four side walls of the carton perpendicular to each other after opening. Utility Model Content

[0004] In order to maintain the four side walls of the paper box in a state where they are perpendicular to each other after the box is opened, the present application provides a paper box material taking and box opening mechanism.

[0005] The paper box material taking and opening mechanism provided in the present application adopts the following technical solution:

[0006] A carton picking and opening mechanism comprises a frame, a placement table, an adsorption assembly and a conveyor line; the placement table is connected to the frame, and the placement table is used to place cartons to be opened; the adsorption assembly is slidably connected to the frame, and the sliding direction of the adsorption assembly relative to the frame is along the length direction of the placement table; the conveyor line is connected to the frame, and the conveyor line is located between the placement table and the adsorption assembly, and the transmission direction of the conveyor line is perpendicular to the length direction of the placement table; the conveyor line comprises a plurality of opening plates, and the opening plates are used to place opened cartons; rigid limit members are provided on both sides of the opening plates, and the limit members are used for the side walls of the carton to fit.

[0007] By adopting the above technical solution, stacks of folded cartons are placed on the placement table, and the adsorption component adsorbs the cartons to the box opening plate. During the movement of the folded carton toward the box opening plate, the limiter forces the carton to open, and finally two side walls of the carton that are away from each other are respectively attached to the limiters on both sides of the box opening plate. The box opening plate with the carton placed on it and the carton in the opened state move to the next process along the conveyor line. During the movement, under the action of the limiter, the carton always maintains a state in which the four side walls are perpendicular to each other.

[0008] Optionally, the end of the limiting member close to the placement table has a first guide surface, and the distance between the first guide surface and the center line of the box opening plate gradually decreases from one end close to the placement table to the other end.

[0009] By adopting the above technical solution, the first guide surface is used to guide the paper box entering the box opening plate. On the one hand, the paper box can enter the box opening plate smoothly. On the other hand, the side wall of the paper box can be smoothed to a certain extent when the paper box enters the box opening plate, thereby reducing the risk of deformation during the movement of the paper box.

[0010] Optionally, the end of the box opening plate close to the placement table has a second guide surface, and the distance between the second guide surface and the horizontal ground gradually increases from one end close to the placement table to the other end.

[0011] In order to ensure the smooth movement of the first conveyor line and reduce wear, there is usually a certain gap between the box opening plate and the placement table. By adopting the above technical solution, the second guide surface is used to guide the bottom of the paper box, so that the paper box can be smoothly moved from the placement table to the box opening plate; on the other hand, the gap between the box opening plate and the placement table forms a short collision when the folded paper box moves to the second guide surface, which assists in opening the bottom of the paper box and reduces the risk of deformation of the paper box during the box opening process.

[0012] Optionally, the conveyor line further includes a conveyor belt; the box opening plate includes two sub-plates, and the limiting members on both sides of the box opening plate are respectively arranged on the two sub-plates; and both sub-plates can be detachably connected to the conveyor belt.

[0013] By adopting the above technical solution, on the one hand, the box opening plate is divided and arranged to facilitate the turning over of the conveyor belt; on the other hand, when opening paper boxes of different sizes, the sub-plates with limit members of different thicknesses are replaced to improve the flexibility of the box opening mechanism.

[0014] Optionally, the placement platform is a transmission belt.

[0015] By adopting the above technical solution, when the number of cartons on the placement table decreases, the placement table drives the cartons to move a certain distance toward the conveyor line to facilitate loading.

[0016] Optionally, baffles are provided on both sides of the end of the placement table close to the conveying line, and the baffles are used for the paper box to abut against.

[0017] By adopting the above technical solution, the baffle is used to block the cartons on the placement table to a certain extent, thereby reducing the risk of stacked cartons collapsing, and at the same time allowing the cartons to be placed vertically, making it easier to take out the materials.

[0018] Optionally, the baffle is arranged in an arc shape.

[0019] By adopting the above technical solution, the risk of deformation of the paper box during the process of moving toward the box opening plate is reduced.

[0020] Optionally, the placement table has a placement surface and a loading surface, and the distance between the placement surface and the horizontal ground gradually increases from the end close to the conveyor line to the other end; the loading surface is located at one end of the placement surface close to the conveyor line, and the distance between the loading surface and the horizontal ground gradually decreases from one side close to the first conveyor line to the other side.

[0021] By adopting the above technical solution, the placement surface is tilted so that after the paper box closest to the conveyor line is taken away, the subsequent paper boxes slide towards the conveyor line under the action of their own gravity to facilitate loading; then the loading surface blocks the stacked paper boxes to reduce the risk of collapse of the stacked paper boxes.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting limiters on both sides of the box opening plate, the two side walls of the carton that are away from each other are limited by the limiters, so that after the carton is opened, it is always in a state where four pairs of two are perpendicular to each other during the subsequent transportation process, which is convenient for the subsequent process;

[0024] 2. By setting a first guide surface on the limiting member, setting a second guide surface on the box opening plate, and making the baffle plate arc-shaped, the paper box can smoothly enter the box opening plate from the placement table;

[0025] 3. By providing the placement table with an inclined placement surface and a reversely inclined loading surface, the stack of paper boxes can slide toward the conveyor line under the action of their own gravity without collapsing, thereby facilitating loading.

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The embodiment of the present application discloses a paper box taking and opening mechanism.

[0032] Example 1

[0033] Reference Figure 1 , the carton picking and opening mechanism includes a frame 1, a placement table 2, an adsorption component 3 and a conveyor line 4. The placement table 2 is connected to the frame 1, and the placement table 2 is used to place the carton to be opened. The adsorption component 3 is slidably connected to the frame 1, and the sliding direction of the adsorption component 3 relative to the frame 1 is along the length direction of the placement table 2. The conveyor line 4 is connected to the frame 1, and the conveyor line 4 is located between the placement table 2 and the adsorption component 3, and the transmission direction of the conveyor line 4 is perpendicular to the length direction of the placement table 2. The conveyor line 4 includes a plurality of box opening plates 41, and the box opening plates 41 are arranged at intervals along the conveying direction of the conveyor line 4. Rigid limit members 411 are provided on both sides of the box opening plates 41, and the limit members 411 are used to fit the side walls of the paper supply box. When the box opening mechanism is working, the adsorption component 3 adsorbs the folded paper box on the placement table 2 to the box opening plate 41. In the process of the paper box entering the box opening plate 41, the two side walls of the paper box that are away from each other respectively abut against the limiting members 411 on both sides of the box opening plate 41. Under the forcing action of the limiting members 411, the paper box is finally in an open state. After that, when the conveyor line 4 moves, the open box opening plate 41 and the paper box are sent to the next process together.

[0034] Specifically, the frame 1 is connected to a driving member 11 for driving the adsorption assembly 3 to move. The driving member 11 can be an existing driving structure such as a cylinder, a hydraulic cylinder or a linear drive motor, which will not be described in detail here.

[0035] The adsorption assembly 3 includes a connection block and a vacuum suction cup, and the connection block is connected to the output shaft of the driving member 11. A plurality of vacuum suction cups are provided, and the plurality of vacuum suction cups are evenly distributed on the connection block.

[0036] In this embodiment, the limiting member 411 is a plate-shaped structure, and two limiting members 411 are provided. In other embodiments, a plurality of limiting members 411 may also be provided, and the plurality of limiting members 411 are separately provided on both sides of the box opening plate 41.

[0037] The conveyor line 4 further includes a conveyor belt 42 , and a plurality of box opening plates 41 are arranged on the conveyor belt 42 at intervals along the length direction of the conveyor belt 42 . The plurality of box opening plates 41 can be detachably connected to the conveyor belt 42 .

[0038] Specifically, refer to Figure 1 and Figure 2, the box opening plate 41 includes two sub-plates 412, two stoppers 411 are respectively connected to the two sub-plates 412, and the two sub-plates 412 are detachably connected to the conveyor belt 42 by bolts. With this design, on the one hand, it is convenient to adjust the distance between the two stoppers 411 by adjusting the distance between the two sub-plates 412, so that the box opening plate 41 is suitable for paper boxes of different sizes; on the other hand, it is convenient for the conveyor belt 42 to turn smoothly at the turning point. It can be understood that in other embodiments, the stoppers 411 can also be detachably connected to the box opening plate 41, and when it is necessary to adapt to paper boxes of different sizes, the stoppers 411 of different thicknesses can be replaced.

[0039] Reference Figure 2 The end of the stopper 411 close to the placement table 2 has a first guide surface 413, and the distance between the first guide surface 413 and the center line of the box opening plate 41 gradually decreases from one end close to the placement table 2 to the other end. The end of the box opening plate 41 close to the placement table 2 has a second guide surface 414, and the distance between the second guide surface 414 and the horizontal ground gradually increases from one end close to the placement table 2 to the other end. That is, the first guide surface 413 and the second guide surface 414 are arranged obliquely, so that the first guide surface 413 is used to guide the side wall of the paper box, and the second guide surface 414 is used to guide the bottom of the paper box, so that the paper box can smoothly enter the box opening plate 41, while reducing the risk of deformation of the paper box in the process of entering the box opening plate 41.

[0040] Furthermore, the placement table 2 is a transmission belt, so that the stacked paper boxes can be moved toward the conveyor line 4 under the transportation of the placement table 2, thereby improving the automation of the conveying mechanism.

[0041] Reference Figure 2 Two baffles 21 are provided at the end of the placement table 2 close to the conveyor line 4. The two baffles 21 are respectively connected to the two sides of the placement table 2, and the two baffles 21 are both arranged in an arc shape, so that the baffles 21 form a certain barrier for the stacked paper boxes, reducing the risk of the stacked paper boxes tipping over under the action of their own gravity. At the same time, since the baffles 21 are arranged in an arc shape, when the adsorption component 3 adsorbs the paper box, the paper box can still leave the placement table 2 smoothly under the guidance of the baffle 21.

[0042] The implementation principle of Example 1 is as follows: when the box opening mechanism is working, the adsorption component 3 adsorbs the folded paper box on the placement table 2 to the box opening plate 41, and the paper box enters the box opening plate 41 through the baffle 21, the second guide surface 414 and the first guide surface 413; in the process of the paper box entering the box opening plate 41, the two side walls of the paper box that are away from each other are respectively abutted against the limiting members 411 on both sides of the box opening plate 41, and under the forcing action of the limiting members 411, the paper box is finally in an open state, and then the conveyor line 4 moves to send the opened box opening plate 41 and the paper box to the next process together.

[0043] Example 2

[0044] Reference Figure 3 The difference between this embodiment and the embodiment 1 is that the placement table 2 is fixedly connected to the frame 1, and the placement table 2 has a placement surface 22 and a loading surface 23. The distance between the placement surface 22 and the horizontal ground gradually increases from one end close to the conveyor line 4 (refer to the conveyor line 4 in the embodiment 1) to the other end. That is, the placement surface 22 is set at an angle. When a paper box is moved to the box opening plate 41 by the adsorption component 3, the subsequent paper boxes slide down along the placement table 2 under the action of their own gravity to facilitate loading. At the same time, the adjacent paper boxes on the placement table 2 are staggered to reduce the risk that the adjacent paper boxes are moved to the box opening plate 41 at the same time due to excessive mutual adsorption force.

[0045] The loading surface 23 is connected to one end of the placement surface 22 close to the conveyor line 4, and the distance between the loading surface 23 and the horizontal ground gradually decreases from one side close to the conveyor line 4 to the other side. Therefore, when the placement surface 22 is tilted, the loading surface 23 is used to block the stacked paper boxes, reducing the risk of the stacked paper boxes collapsing, and the loading surface 23 is used to guide the paper boxes, so that the paper boxes can smoothly enter the box opening plate 41 (refer to the box opening plate 41 in Example 1) from the placement table 2.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
