[0026] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0027] See also Figure 1 and Figure 2 The present invention discloses an automatic bagging machine 100, which is suitable for packing a mobile phone case 200 into an ultra-thin film bag 300, so as to protect the mobile phone case 200 during transportation and handling. Specifically, in the present application, the film bag 300 is roughly rectangular, with three sides closed and one side open. The film bag 300 is a flat sheet when it is not opened. A plurality of flat film bags 300 can be stacked in the automatic bagging machine 100, so as to facilitate subsequent automatic loading. When the mobile phone case 200 is loaded, the bag mouth of the flat film bag 300 needs to be opened so that the mobile phone case 200 can be loaded into the film bag 300 through the opened bag mouth.

[0028] First combine Figures 1 to 3 , the overall structure of the automatic bagging machine 100 disclosed in the preferred embodiment of the present invention is described:

[0029] The automatic bagging machine 100 includes a frame 101, a platform 102 disposed on the frame 101, and a housing 103 installed on the frame 101 for protection. The automatic bagging machine 100 also includes a bag-feeding device 10 and a bag-opening device 20 arranged along the longitudinal straight line of the platform 102, a bag-supplying device 30, a bag-taking device 40, a detection device 50, and a bag-feeding device 60 arranged along the transverse straight line of the platform 102, and the bag-feeding device 60 is located beside the bag-opening device 20. The whole machine is in an L-shaped layout, and the structure is simple and compact.

[0030] Among them, the bag taking device 40 is used to take and place the stacked film bags 300 in the bag supply device 30 one by one to the detection device 50, and in the process of taking and placing, the film bag 300 on the top layer is first sucked and then the film bag 300 is rotated by a certain angle to separate it from the film bag 300 on the lower layer for transfer. The angle range of the film bag 300 rotated by the bag taking device 40 is approximately 5° to 10°, that is, a small twist, similar to the action of rubbing with fingers. The bag taking device 40 normally only takes and delivers one film bag 300, and occasionally takes and delivers two films at a time. In order to avoid this situation, when the bag feeding device 60 sucks the film bag 300 from the upper side and transfers the film bag 300 from the detection device 50 to the bag opening device 20, the detection device 50 can provide adsorption force from the lower side to suck the extra film bag 300, thereby further ensuring that the bag feeding device 60 can only suck and deliver one film bag 300 to the bag opening device 20 at a time, that is, the detection device 50 can be used to detect whether only one film bag 300 is placed thereon.

[0031] In addition, the bag feeding device 60 also cooperates with the bag opening device 20 to fix the film bag 300 at the bag opening device 20 from the upper and lower sides respectively. The bag feeding device 60 can also move up and down relative to the bag opening device 20 to pull the film bag 300 so that the bag opening of the film bag 300 is opened, and the bag entering device 10 can move linearly relative to the bag opening device 20 to push the mobile phone case 200 from the opened bag opening into the film bag 300.

[0032] In order to facilitate the unloading of the bagged mobile phone cases 200, the automatic bagging machine 100 of the present invention also includes a unloading device 70 arranged in a straight line on the rear side of the bag opening device 20. The bagging device 10 pushes the mobile phone cases 100 loaded in the film bag 300 from the bag opening device 20 to the unloading device 70, and then the unloading device 70 conveys the bagged mobile phone cases 200 backwards in sequence for unloading.

[0033] It should be noted that the automatic bagging machine 100 of the present invention also includes a control system (not shown in the figure), which is electrically connected to the bag entering device 10, the bag opening device 20, the bag supplying device 30, the bag taking device 40, the detection device 50, the bag delivering device 60 and the unloading device 70, and the coordinated actions between the devices are controlled by the control system. Among them, the control system is an existing design, and its structure and control principle are well known in the art, so it will not be described in detail here.

[0034] Please see below Figures 2 to 9 , the structure of each device of the automatic bagging machine 100 of the present invention is described:

[0035] See also Figure 3The bag supply device 30 includes a bottom support 31, a limit frame 32 arranged around the bottom support 31, an ion air knife 33 arranged at the frame opening of the limit frame 32, and a lifting driver 34 connected to the bottom support 31. The bottom support 31 and the limit frame 32 enclose a placement space 30a for stacking film bags 300. The lifting driver 34 can drive the bottom support 31 to move up and down linearly relative to the limit frame 32, so that the stacked film bags 300 are pushed to the position close to the ion air knife 33 in sequence. The ion air knife 33 is used to eliminate the static electricity between the top film bag 300 and the lower film bag 300, so as to separate the two. Among them, the limit frame 32 can be fixed on the machine 102 by its folded edge, or it can be fixed by a carrier plate 35 installed on the machine 102. The bottom support 31 is movably connected to the carrier plate 35, and an opening is opened on the carrier plate 35 for the output end of the lifting driver 34 to enter and exit. In order to optimize the structure and reduce the volume, the lifting driver 34 can be installed on the carrier 12 or the carrier plate 35 and located below the carrier 12, and its output end is connected to the bottom bracket 31 from the bottom. The lifting driver 34 is specifically a linear motor.

[0036] Preferably, in order to better achieve the separation between the ultra-thin film bags 300, the bag supply device 30 also includes a stopper 36 embedded in the inner wall of the stopper frame 32, and the side of the stopper 36 with a rough surface is located in the placement space 30a. The stopper 36 increases the friction between the top film bag 300 and the lower film bag 300 through its rough surface, so as to separate the two. Specifically, the stopper 36 can form a rough surface by providing a protrusion or thread on its surface. The number of the stopper 36 is multiple, and the multiple stoppers 36 can be arranged along the circumference of the limit frame 32. When the film bag 300 is sucked upward and passed through the stopper 36, the edge of the film bag 300 is similar to being scratched by the protrusion or thread on the stopper 36, so that the film bag 300 of the lower layer that may be brought up is left in the placement space 30a. Under the cooperation of the ion air knife 33, the bag taking device 40 and the stopper 36, the stacked film bags 300 can be further effectively separated, so that the bag taking device 40 only takes and puts one film bag 300 to the detection device 50 at a time in a normal state. Although only in some cases, two film bags 300 are taken and sent to the detection device 50 at one time, in order to ensure that the bag delivery device 60 can only suck and send one film bag 300 to the bag opening device 20 at a time, the suction nozzle on the detection device 50 provides an adsorption force from bottom to top, and the adsorption force is smaller than the adsorption force from top to bottom provided by the bag delivery device 60, so that the adsorption action of the detection device 50 does not affect the normal transfer of one film bag 300, and can also leave the film bags 300 that are taken and put more on the detection device 50, effectively ensuring the smooth implementation of the next process.

[0037] See also Figure 2 , Figure 4 and Figure 5In order to simplify the structure and improve efficiency, the distance between the bag supply device 30 and the detection device 50, the distance between the detection device 50 and the bag opening device 20, and the distance between the bag taking device 40 and the bag delivering device 60 are correspondingly arranged, so that the bag taking device 40 and the bag delivering device 60 can synchronously move back and forth between the bag supply device 30 and the detection device 50 and between the detection device 50 and the bag opening device 20, that is, when the bag taking device 40 takes and places the film bag 300 from the bag supply device 30 to the detection device 50, the bag delivering device 60 sucks the previous film bag 300 at the bag supply device 30 to the bag opening device 20, thereby reducing the standby time, effectively balancing the production line and improving efficiency.

[0038] Specifically, the bag picking device 40 and the bag delivering device 60 are installed on a gantry 104 and are respectively connected to the output end of the transverse movement module 105 installed on the gantry 104. The transverse movement module 105 can drive the bag picking device 40 and the bag delivering device 60 to reciprocate along the lateral straight line of the machine 102. In the initial position, the bag picking device 40 and the bag delivering device 60 are respectively located directly above the bag supply device 30 and the detection device 50. The bag taking device 40 includes a pick-and-place driver 41, a mounting frame 42, a rotation driver 43, a rotating frame 44 and a vacuum suction nozzle 45 installed at the output end of the transverse movement module 105 of the gantry 104. The mounting frame 42 is connected to the output end of the pick-and-place driver 41, the rotation driver 43 is installed on the mounting frame 42, the rotating frame 44 is rotatably installed on the mounting frame 42 and connected to the output end of the rotation driver 43, and a plurality of vacuum suction nozzles 45 are arranged on the rotating frame 44, and the plurality of vacuum suction nozzles 45 are specifically arranged in a straight line. The pick-and-place driver 41 can drive the mounting frame 42 to drive the vacuum suction nozzle 45 to move up and down in a straight line to take and put bags, and the rotation driver 43 can drive the rotating frame 44 to rotate relative to the mounting frame 42 to drive the vacuum suction nozzle 45 to rotate. The pick-and-place driver 41 is specifically a linear cylinder, and the rotation driver 43 is specifically a rotary cylinder.

[0039] See also Figure 6The mounting frame 42 and the rotating frame 44 are two U-shaped frames, one large and one small. The two side plates 441 of the rotating frame 44 are rotatably connected to the two side plates 421 of the mounting frame 42. There is a certain gap between the bottom plate 442 of the rotating frame 44 and the bottom plate 422 of the mounting frame 42. When the rotating frame 44 rotates relative to the mounting frame 42, the bottom plate 422 of the mounting frame 42 can block its rotation because the gap between the two is relatively small, so that the rotating frame 44 rotates relative to the mounting frame 42 within a limited angle range. Specifically, the output shaft of the rotary driver 43 is connected to a driving wheel 46, and a driven wheel 47 is installed on a side plate 421 of the mounting frame 42. The driving wheel 46 and the driven wheel 47 are connected by a synchronous belt 48, and the opposite side plate 441 of the rotating frame 44 is connected to the driven wheel 47. When the rotary driver 43 drives the driving wheel 46 to rotate, the driven wheel 47 can drive the rotating frame 44 to rotate relative to the mounting frame 42, thereby driving the vacuum suction nozzle 45 to rotate.

[0040] See also Figure 5 and Figure 7 The bag feeding device 60 is connected to a transfer driver 61 at the output end of the transverse module 105 installed on the gantry 104, a mounting plate 62 connected to the output end of the transfer driver 61, and a transfer suction cup 63 installed on the mounting plate 62. The transfer driver 61 can drive the transfer suction cup 63 to move up and down linearly to absorb and transfer the film bag 300. Among them, the mounting plate 62 and the transfer suction cup 63 can be connected to the guide rod 65 through a linear bearing 64, and a spring 66 is also connected between the transfer suction cup 63 and the mounting plate 62 to prevent the transfer driver 61 from moving too fast or too quickly and damaging the transfer suction cup 63. The transfer suction cup 63 is a vacuum suction cup, and a suction nozzle 631 can be provided at each of its four top corners to fix the film bag 300 as a whole, and a plurality of suction nozzles 632 are provided at the position of the front end corresponding to the bag opening of the film bag 300, so as to cooperate with the bag opening device 20 to open the bag opening. The transfer driver 61 is specifically a linear cylinder.

[0041] See also Figure 8 and Fig. 9The bag opening device 20 includes a positioning plate 21 and an opening member 22 which are arranged opposite to each other. A bag opening suction cup 23 for fixing the bag opening of the film bag 300 from the bottom is provided at the front end of the positioning plate 21. A positioning suction cup 24 for fixing the entire film bag 300 from the bottom is provided at the relative center of the positioning plate 21. Both the bag opening suction cup 23 and the positioning suction cup 24 are vacuum suction cups and are arranged lower than or flush with the upper end surface of the positioning plate 21. After the bag opening suction cup 23 cooperates with the transfer suction cup 63 to suck the film bag 300 from the upper and lower sides to open its bag opening, the opening member 22 can move linearly relative to the positioning plate 21, so that the opening member 22 can be inserted into the film bag 300 from the bag opening of the film bag 300, and the opening member 22 can also move linearly in the film bag 300 toward the left wall or / and right wall of the film bag 300 to tighten the bag opening of the film bag 300, so that the mobile phone case 200 can be put into the bag more smoothly.

[0042] Specifically, the positioning plate 21 is mounted on the machine table 102 and can be arranged flush with the detection device 40, thereby effectively shortening the moving stroke of the bag feeding device 60. The positioning plate 21 can also be provided with a graphic mark corresponding to the shape of the film bag 300, so as to achieve positioning and placement simply and quickly. In addition, the positioning plate 21 is also provided with a position sensor 25 to sense whether the film bag 300 is in place and send a sensing signal to the control system.

[0043] Specifically, the opening member 22 is also mounted on the machine 102, and the bag opening device 20 further includes a mounting seat 26 mounted on the machine 102, an insertion driver 27 mounted on the mounting seat 26, and a tensioning driver 28 connected to the output end of the insertion driver 27. The front side end of the positioning plate 21 is provided with an opening member 22 at the positions of the left and right side walls of the film bag 300, and the two opening members 22 are connected to the output end of the tensioning driver 28. The insertion driver 27 can drive the two opening members 22 to move linearly forward and backward toward or away from the bag opening of the film bag 300 to insert or withdraw the film bag 300, and the tensioning driver 28 can drive the two opening members 22 inserted into the bag opening to move toward or away from each other, so as to tighten the bag opening. The opening member 22 is in the form of a sheet, and the insertion driver 27 and the tensioning driver 28 are both linear cylinders.

[0044] Preferably, in order to simplify the structure and reduce the manufacturing cost, the mounting seat 26 can be directly mounted and fixed on the bottom of the positioning plate 21, so that the opening member 22 does not need to move up and down for alignment, but only needs to move forward and backward and left and right. In addition, in order to improve the adaptability of the whole machine, corresponding to the size of the film bag 300, the bag opening device 20 can be provided with two groups of opening members, and the distance between the two opening members 22 in each group corresponds to a film bag 300 of one size, which can also further improve the efficiency.

[0045] Combination Figure 2 and Figure 8The bag-entering device 10 includes a bracket 11, a pushing member 12 and a pushing driver 13 connected to the pushing member 12. The bracket 11 is arranged at the front side of the bag-opening device 20 and has a placement area corresponding to the shape of the mobile phone case 200. The pushing member 12 is suspended at the front end of the bracket 11 and is arranged to abut against the mobile phone case 200 supported on the bracket 11. The pushing driver 13 drives the pushing member 12 to move linearly along the longitudinal direction of the machine 102 to push the mobile phone case 200 to the bag opening of the bag-opening device 20 and into the film bag 300 supported and fixed thereto.

[0046] Specifically, one end of the push member 12 is connected to the output end of the push driver 13, and the other end of the push member 12 abuts against the mobile phone shell 200 on the bracket 11 to form an abutting portion 121. The push driver 13 drives the push member 12 to move linearly toward the bag opening device 40, so that the abutting portion 121 pushes the mobile phone shell 200 from the bag opening 301 of the film bag 300 into the film bag 300. The bottom surface of the abutting portion 121 of the push member 12 is flush with the upper surface of the bracket 11 and the upper surface of the positioning plate 21, so that the mobile phone shell 200 can be pushed into the film bag 300 smoothly. Of course, a weight sensor 14 and a position sensor 15 are provided at the bracket 11 to sense whether the mobile phone shell 200 is placed on the bracket 11 and whether the mobile phone shell 200 is placed accurately. The push driver 13 is specifically a linear motor.

[0047] See also Figure 2 The unloading device 70 located at the rear side of the bag opening device 20 includes two matching conveyor belts 71 and a conveyor driver 72 connected to the two conveyor belts 71 to drive the two conveyor belts 71 to rotate. The bagged mobile phone shell 200 is pushed from the positioning plate 21 to the two conveyor belts 211 by the pushing member 12 for transmission. Among them, a position sensor is provided at the front end of the conveyor belt 71 to sense whether the mobile phone shell 200 is pushed in place. A downwardly inclined guide plate 73 is provided at the rear end of the conveyor belt 71 to facilitate the collection of the bagged mobile phone shell 200. The conveyor driver 72 is specifically a linear motor.

[0048] The following is combined with Figure 1 To Attachment Fig. 9 The specific working principle of the automatic bagging machine 100 of the present application is described as follows:

[0049] First, at the initial position, the bag taking device 40 and the bag delivering device 60 are respectively located above the bag supply device 30 and the detection device 50, and the equipment is started. Under the instruction of the control system, the bag taking device 40 and the bag delivering device 60 move simultaneously, and the bag taking device 40 takes and places a film bag 300 from the bag supply device 30 to the detection device 50. The bag delivering device 60 needs to run empty for the first time, and then when the bag taking device 40 takes and places the second film bag 200, the bag delivering device 60 transfers the first film strip 300 from the detection device 50 to the positioning plate 21 of the bag opening device 20;

[0050] Next, the bag feeding device 60 cooperates with the bag opening device 20 to pull the film bag 300 from the upper and lower sides, so that the bag opening of the film bag 300 is opened, and the opening member 22 is inserted into the film bag 300 with the bag opening opened to open the bag opening. At the same time, the mobile phone case 200 is placed on the bracket 11 by a robot or manually, and the in-position sensor 15 located here senses the mobile phone case 200 and sends a signal to the control system. Under the instruction of the control system, the driving driver 13 drives the pushing member 12 to push the mobile phone case 200 toward the positioning plate 21 for bagging;

[0051] Then, when the bag taking device 40 and the bag feeding device 60 are reset to take and feed the third film bag 300, the driving driver 13 drives the pushing member 12 to push the bagged mobile phone shell 200 to the unloading device 70, and then the pushing member 12 is reset to the bracket 11;

[0052] Finally, the film bag 300 containing the mobile phone shell 200 is conveyed and unloaded by the unloading device 70 .

[0053] By repeating the above operation continuously, the automated assembly line operation of packing the mobile phone shell 200 into the film bag 300 can be realized.

[0054] Compared with the prior art, the automatic bagging machine 100 disclosed in the present invention takes and places the stacked film bags 300 in the bag supply device 30 one by one to the detection device 50 through the bag taking device 40, and in the process of taking and placing, first sucks the film bag 300 on the top layer and then rotates the film bag 300 to a certain angle to separate it from the film bag 300 on the lower layer for transfer, so as to take and place only one film bag 300 at a time as much as possible; in order to prevent taking and placing too many film bags 300, when the bag feeding device 60 sucks the film bag 300 at the detection device 50 from the upper side and transfers it to the bag opening device 20, the detection device 50 is sucked from the lower side. The side provides adsorption force, thereby keeping the multiple film bags 300 taken and placed at the detection device 50, and the detection device 50 further ensures that the bag feeding device 60 can only suck and feed one film bag 300 at a time; and the bag feeding device 60 also cooperates with the bag opening device 20 to fix the film bag 300 from the upper and lower sides of the film bag 300 respectively, and the bag feeding device 60 can also move up and down relative to the bag opening device 20 to pull the film bag 300, thereby opening the bag mouth of the film bag 300, so that the bag entering device 10 that moves linearly relative to the bag opening device 20 can push the mobile phone case 200 from the opened bag mouth into the film bag 300. In addition, since the bag entering device 10 and the bag opening device 20 are arranged along the longitudinal straight line of the machine table 102, the bag supply device 30, the bag taking device 40, the detection device 50 and the bag feeding device 60 are arranged along the transverse straight line of the machine table 102, and the bag feeding device 60 is located next to the bag opening device 20, the automatic bagging machine 100 of the present invention has a simple structure, a reasonable and compact layout, and effectively reduces the volume. Each device only needs to move in a straight line for a short distance to complete the corresponding action, and the movement stroke is short, which effectively improves the efficiency, overcomes the problems existing in the manual bagging of mobile phone cases, realizes the automated assembly line operation of mobile phone case bagging, and effectively reduces the manufacturing cost.

[0055] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
