Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a paper taking device, packaging equipment and a paper taking method. Background Art

[0002] Packaging is a necessary condition for products to enter the circulation field. With the continuous development and progress of technology and the emergence of various foods, new requirements have been put forward for packaging technology and packaging equipment. Packaging equipment is playing an increasingly important role in the circulation field.

[0003] In recent years, due to the advantages of cartons such as environmental protection, low cost, and strong carrying capacity, in order to protect products and facilitate transportation, storage and sales, more and more manufacturers use cartons to package products. Taking the packaging equipment as a wrapping machine as an example, the general operation is: a one-piece carton is placed on the carton bin of the packaging equipment, and then the robot drives the suction cup to suck the carton and place it on the carton placement station, which is convenient for subsequent stacking of products and sealing operations. The inventor found that most of the existing wrapping machines set the robot and suction cup below the carton placement station, and the carton bin is set obliquely above the carton placement station. When it is necessary to take the carton, the robot drives the suction cup to rise until the suction cup contacts the carton and sucks the carton, and then the robot lowers the suction cup until the carton is placed in the carton placement station, and then after the carton is sent away by the conveyor belt, the robot drives the suction cup to rise again and repeats the above action. With the above-mentioned paper picking method, since the robot arm must be raised, lowered, and the carton must be sent away before the next carton can be picked up, the entire process of picking up and placing the carton takes a long time, which is inefficient and cannot meet the needs of automated high-speed production. In addition, since the robot arm is located below the carton placement station, when the carton is placed on the carton placement station, the carton is easily rebounded due to the blocking force of the carton placement station, resulting in inaccurate positioning of the carton, which is not conducive to subsequent operations.

[0004] Therefore, there is an urgent need to design a paper picking device, packaging equipment and paper picking method. When it is necessary to pick up cartons to package products, the operations of picking up and placing cartons can be performed simultaneously, which effectively reduces the time for picking up and placing cartons, greatly improves efficiency, and meets the needs of automated high-speed production. Through the paper picking device of the present application, the carton can be positioned forcefully and accurately at a preset position, further improving the accuracy, which is conducive to subsequent standardized and unified operations, thereby improving the packaging quality.

[0030] The preferred embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein.

Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] At present, when it is necessary to take a carton to package the product, the robot arm usually drives the suction cup to suck the carton, and then places it on the carton placement station. After the carton is sent away by the conveyor belt, the above action is repeated. This way of taking paper requires the robot arm to rise, the robot arm to fall, and the carton to be sent away before the next carton can be sucked. As a result, the entire process of taking and placing paper takes a long time, is inefficient, and cannot meet the needs of automated high-speed production. And because the robot arm is located below the carton placement station, when the carton is placed on the carton positioning slot, the carton is easily moved upwards due to the blocking force of the carton placement station, resulting in inaccurate positioning of the carton, which is not conducive to subsequent operations.

[0034] In response to the above-mentioned problems, an embodiment of the present application provides a paper picking device that can simultaneously perform the operations of picking up and placing cartons, effectively reducing the time for picking up and placing cartons, greatly improving efficiency, and meeting the needs of automated high-speed production. Moreover, through the paper picking device of the present application, the carton can be forcefully and accurately positioned at a preset position, further improving the accuracy, which is facilitating subsequent standardized and unified operations, thereby improving the packaging quality.

[0035] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0036] Embodiment 1:

[0037] See also Figure 1-Figure 7 The first embodiment provides a paper picking device, comprising a turntable 1, a turntable drive assembly 2, N carton suction assemblies 3 and a suction drive assembly. The turntable drive assembly 2 and the suction drive assembly are relatively arranged on both sides of the turntable 1, and the N carton suction assemblies 3 are all arranged on the same surface of the turntable 1, wherein N is a natural number greater than 1. In order to avoid the problem of congestion and heavy weight caused by too many carton suction assemblies 3 on the turntable 1 while placing the carton while sucking the carton, preferably, N is 3, that is, three carton suction assemblies 3 are arranged.

[0038] In order to reduce the weight of the turntable 1 and thus reduce the energy required to drive the turntable 1, as Figure 1-Figure 2 As shown, the overall shape of the turntable 1 is a triangle, and the three carton suction components 3 are respectively arranged at the triangular parts of the turntable 1. Further, in order to facilitate the carton suction components 3 to move toward the center of the turntable 1, the triangular parts of the turntable 1 are chamfered. In order to facilitate lightness and durability, the turntable 1 is made of aluminum alloy.

[0039] The output end of the turntable drive assembly 2 is connected to the turntable 1 for driving the turntable 1 to rotate. Specifically, the turntable drive assembly 2 includes a turntable drive motor 21, which is connected to the turntable 1 for driving the turntable 1 to rotate. In order to make the turntable 1 move more stably, the turntable drive assembly 2 also includes a rotating shaft 22 and a mounting plate 7, wherein the mounting plate 7 is provided with a mounting through hole, and the rotating shaft 22 and the turntable drive motor 21 are arranged on both sides of the mounting through hole. More specifically, the turntable drive motor 21 is connected to the mounting plate 7 through a motor mounting seat, and the output end of the turntable drive motor 21 is connected to the rotating shaft 22 for driving the rotating shaft 22 to rotate, and one end of the rotating shaft 22 is connected to the mounting plate 7, and the other end is connected to the turntable 1 through a screw. The rotating shaft 22 is driven by the turntable driving motor 21 to rotate, thereby driving the turntable 1 to rotate 360 ​​degrees, and further driving the carton suction assembly 3 located on the turntable 1 to rotate synchronously.

[0040] In order to prevent the turntable 1 from being unstable due to uneven force during rotation, the N carton suction components 3 are evenly arranged along the circumferential direction of the turntable 1, and the driving direction of the N carton suction components 3 is toward the center of the turntable 1. Figure 1As shown, the carton suction assembly 3 includes a suction cup mounting seat 31, a vacuum pumping device, and a plurality of suction cups 32. The suction cup mounting seat 31 is slidably connected to the turntable 1. The plurality of suction cups 32 are arranged in a row at one end of the suction cup mounting seat 31 and are connected to the vacuum pumping device. Specifically, the suction cup mounting seat 31 includes a mounting groove, and three vacuum suction cups 32 are arranged in parallel in the mounting groove, and the opening of the vacuum suction cup 32 is higher than the suction cup mounting seat 31, so as to facilitate the suction of the carton 8. The suction cup mounting seat 31 slides relative to the turntable 1, thereby driving the suction cup 32 to move. When the vacuum pumping device is turned on, the vacuum suction cup 32 can suck the carton and reach the next station under the rotation of the turntable 1.

[0041] Specifically, Figure 2-Figure 7 As shown, the carton suction component 3 includes a first suction component 3A, a second suction component 3B and a third suction component 3C. When it is necessary to take a carton, the first suction component 3A, the second suction component 3B and the third suction component 3C are extended at the same time, wherein the first suction component 3A sucks the carton located obliquely above, and then the carton suction component 3 retracts. At the same time, the turntable 1 rotates counterclockwise by 120 degrees under the drive of the turntable drive motor 21, and the carton suction component 3 extends. At this time, the first suction component 3A places the carton on the carton placement station, and the second suction component 3B is ready The third suction component 3C sucks the carton; then the carton suction component 3 retracts, the turntable 1 rotates 120 degrees, and the above operation is repeated, thereby completing the operation of synchronously taking and placing the carton, which greatly improves the efficiency. By arranging the carton suction component 3 above the carton placement station, when placing the carton, the carton suction component 3 can give the carton a downward pressure, so that the carton can be placed on the carton placement station more accurately and stably, effectively avoiding the problem of insufficient carton placement force caused by the use of a robot in the prior art, resulting in the carton shifting due to upward rebound.

[0042] The suction drive assembly is connected to the N carton suction assemblies 3, and is used to drive the N carton suction assemblies 3 to move synchronously. Specifically, the suction drive assembly includes a suction drive motor 41, a gear 42, a bearing 43 and N racks 44, wherein the N is 3. The bearing 43 is arranged at the central through hole of the turntable 1, and the central through hole is arranged at the center of the turntable 1. More specifically, the bearing 43 is connected to the rotating shaft 22, and extends to the suction drive motor 41 through the mounting through hole on the turntable 1. The output shaft of the suction drive motor 41 is connected to the gear 42, and is used to provide power to the gear 42. The gear 42 is arranged on the turntable 1 through the bearing 43, and the plane where the gear 42 is located is parallel to the plane where the turntable 1 is located.

[0043] N racks 44 are slidably disposed on the turntable 1. Specifically, the N racks 44 are respectively connected to the N carton suction assemblies 3 and mesh with the gears 42. In order to make the movement of the carton suction assembly 3 more stable, the suction drive assembly further includes N linear guides 45 and sliders 46. The N linear guides 45 are evenly disposed along the circumferential direction of the turntable 1, and the length direction of the N linear guides 45 is consistent with the length direction of the N racks 44; the sliders 46 are slidably disposed on the linear guides 45 and connected to the carton suction assembly 3.

[0044] like Figure 1-Figure 3 As shown, the rack 44 includes a first rack 441, a second rack 442 and a third rack 443, and the first rack 441, the second rack 442 and the third rack 443 are centered on the gear 42 and are arranged on the turntable 1 in a triangle shape as a whole. Correspondingly, three linear guide rails are also provided, and are respectively arranged on the inner sides of the first rack 441, the second rack 442 and the third rack 443. One end of the rack 44 is connected to the outer surface of the suction cup mounting seat 31, and the inner surface of the suction cup mounting seat 31 is slidably connected to the linear guide rail 45 through the slider 46. That is, the rack 44, the suction cup mounting seat 31, the slider 46, the linear guide rail 45 and the turntable 1 are arranged in sequence from the outside to the inside. It should be noted that the direction from the outside to the inside in this embodiment is the direction from the suction drive motor 41 to the turntable drive motor 21.

[0045] In order to make the movement of the rack 44 more stable and more accurate, the paper picking device further includes N positioning guide wheels 5; the N positioning guide wheels 5 are arranged on the rotating disk 1 and abut against the tooth backs of the rack 44. Specifically, there are three N positioning guide wheels 5, which are arranged on one side of the rack 44 and abut against the tooth backs of the first rack 441, the second rack 442 and the third rack 443 respectively.

[0046] Furthermore, since the rotation direction of the turntable 1 is generally counterclockwise or clockwise, in order to prevent the wires or vacuum tubes from getting stuck due to the rotation of the turntable 1, the paper picking device further includes an air slip ring 6; the air slip ring 6 is arranged between the suction drive motor 41 and the gear 42, and is sleeved on the output shaft of the suction drive motor 41. By passing the wires or vacuum tubes through the pulley and the gear 42, the problem of the wires and vacuum tubes getting stuck due to the rotation of the turntable 1 is effectively avoided.

[0047] In the first embodiment of the present invention, through the mutual cooperation of the turntable, the turntable drive assembly, N carton suction assemblies and the suction drive assembly, when it is necessary to move the carton located obliquely above to the carton placement station below, the suction drive assembly moves forward to drive the carton suction assembly to extend until the carton suction assembly abuts against the surface of the carton to be sucked; vacuum is drawn so that the carton suction assembly sucks the carton; then the suction drive assembly is started to move in the reverse direction and the turntable drive assembly is rotated 120 degrees at the same time to move the carton to the top of the carton placement station, the suction drive assembly moves forward to drive the carton suction assembly to extend, and the sucked carton is placed on the carton placement station, and at the same time, the carton suction assembly that has not sucked the carton abuts against the surface of the carton to be sucked, thereby continuously realizing the synchronous operation of taking and placing the carton. Compared with the inefficient method of using a robot to drive a suction cup to suck up cartons in the prior art, the paper picking device provided in the present application can simultaneously perform the operations of picking up and placing cartons, effectively reducing the time for picking up and placing cartons, greatly improving efficiency, and meeting the needs of automated high-speed production. Moreover, through the paper picking device of the present application, the carton can be forcefully and accurately positioned at a preset position, further improving accuracy, which is conducive to subsequent standardized and unified operations, thereby improving packaging quality.

[0048] Embodiment 2:

[0049] Corresponding to the above-mentioned paper picking device, the second embodiment of the present application also provides a packaging device, see Figure 1-Figure 7 , specifically:

[0050] Based on the structure of the above embodiment 1, the packaging equipment provided in the second embodiment includes a wrapping machine, a packaging machine or other machines that need to use cartons to package products. Specifically, the packaging equipment includes a frame, a carton bin, a material unloading conveyor line and the above-mentioned paper picking device, and the carton bin, the material unloading conveyor line and the paper picking device are all arranged on the frame.

[0051] More specifically, the paper picking device is connected to the frame via a mounting plate 7; the carton bin is disposed obliquely above the paper picking device for placing a single-piece carton (i.e., the carton to be sucked); a carton placing station is provided on the unloading conveyor line; the carton placing station is disposed directly below the paper picking device for placing the carton 8 sucked by the paper picking device.

[0052] The specific structure and operation steps of the paper picking device are detailed in the above-mentioned embodiment 1 and will not be repeated here.

[0053] In the embodiment of the present application, when it is necessary to package the product in cartons, the paper picking device sucks the carton located on the carton bin and drives the carton to move above the carton placement station, and then extends the carton picking component, and then accurately and stably positions the carton on the carton placement station under the gravity of the carton picking component, and then the carton picking component, the turntable and the unloading conveyor line act synchronously (that is, the carton picking component retracts, the turntable rotates 120 degrees and the unloading conveyor line moves forward to transport the carton to the next packaging station at the same time), and then the above actions are repeated continuously to complete the automatic carton picking and carton placing operations. Compared with the prior art in which the mechanical arm is set below the carton placement station, which results in the need to complete the mechanical arm raising, the mechanical arm descending and the carton being sent away before the next carton picking cycle can be performed, resulting in low efficiency, the packaging equipment provided in the embodiment of the present application can simultaneously perform the operations of picking up, placing and delivering cartons, greatly improving efficiency, reducing the time for picking up paper, and helping enterprises achieve the goal of improving quality and increasing efficiency.

[0054] Embodiment three:

[0055] Corresponding to the above-mentioned paper picking device, the third embodiment of the present application also provides a paper picking method, see Figure 1-Figure 8 , specifically:

[0056] Based on the structure of the above embodiment, the embodiment of the present application further provides a paper picking method, which is implemented based on the above paper picking device and specifically includes the following steps:

[0057] S1, the suction drive assembly moves forward, driving the carton suction assembly to extend until the carton suction assembly abuts against the surface of the carton to be sucked;

[0058] S2, vacuuming so that the carton suction component sucks the carton;

[0059] S3, the suction drive assembly moves in the reverse direction, driving the carton suction assembly to retract, and at the same time, the turntable drive assembly drives the turntable to rotate 120 degrees;

[0060] S4, the suction drive assembly moves forward, driving the carton suction assembly to extend, and simultaneously placing the carton at a preset position and taking the carton;

[0061] S5. The turntable driving assembly drives the turntable to rotate 120 degrees, and the above steps are repeated continuously.

[0062] In S1, Figure 4 As shown, Figure 4 1 is a schematic diagram of the first state of the paper picking device, which is a schematic diagram of the state of the paper picking device when picking up a carton. Before sucking up a carton, the turntable 1 and the carton sucking assembly 3 are returned to the origin, and the sucking drive motor 41 is turned on to rotate forward, so that the suction cup 32 is extended until the suction cup 32 (i.e., the first sucking assembly 3A) located near the carton to be sucked abuts against the surface of the carton to be sucked.

[0063] In S2 , vacuum is drawn so that the suction cup 32 of the first suction component 3A forms a negative pressure to firmly suck the carton onto the suction cup 32 .

[0064] In S3, such as Figure 5-Figure 6 As shown, the suction drive motor 41 is reversed, so that the suction cup 32 in the first suction assembly 3A retracts with the carton, and at the same time, the circle drive motor rotates, driving the turntable 1 to rotate 120 degrees counterclockwise, that is, the carton suction assembly 3 (i.e., the first suction assembly 3A) located obliquely above and sucking the carton is rotated to the bottom of the spur gear 42. It should be noted that the carton placed on the carton placement station is also sent to the next process station by the unloading conveyor line at this time (i.e., within the time when the turntable 1 rotates 120 degrees).

[0065] In S4, Figure 7 As shown, the suction drive motor 41 rotates forward, so that the suction cup 32 in the first suction assembly 3A extends with the carton, and the carton is placed on the carton placement station. It should be noted that at this time, one of the other two carton suction assemblies 3 (i.e., the third suction assembly 3C) is in contact with the surface of the carton to be sucked, and the other carton suction assembly (i.e., the second suction assembly 3B) is on standby, waiting for the turntable 1 to rotate 120 degrees to suck the carton 8.

[0066] In S5, the vacuum is disconnected so that the carton on the first suction component 3A can be separated from the suction cup 32 and positioned on the carton placement station. Then, the turntable driving component 2 drives the turntable 1 to rotate 120 degrees counterclockwise, and the above actions are repeated continuously.

[0067] It should be noted that when vacuuming, in order to reduce the number of vacuuming equipment and reduce costs, a solenoid valve can be installed on the vacuuming equipment. By controlling the solenoid valve, the three carton suction components can be independently vacuumed to facilitate the suction of cartons and complete the operation of moving the stacked cartons to the carton placement station.

[0068] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0069] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0070] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
