Description

Technical Field

[0001] The present invention relates to the technical field of paging, and in particular to an adsorption paging method and device. Background Art

[0002] The paging machine can be used in conjunction with the inkjet printer or independently, which can improve the worker's working speed, save working time, labor and reduce production costs. It is mainly used to automatically separate the stacks of plastic bags, packaging bags, cards or papers of various specifications and transfer them to the conveyor belt as single pieces, so that the inkjet printer or laser machine can print and engrave the production date, batch number, anti-counterfeiting mark, pattern, etc., thereby reducing the tediousness of manual paging, giving full play to the advantages of high-speed printing of inkjet printers and laser machines, and improving the efficiency of printing.

[0003] At present, for relatively soft materials, only negative pressure adsorption can be used for paging feeding. Among them, when using negative pressure adsorption, a photoelectric switch or a travel switch is used to detect whether the surface of the material has contacted the negative pressure adsorption suction cup, and a signal is given to generate the adsorption action of the suction cup to realize the feeding action. This method is still feasible for materials with a flat surface, a relatively regular appearance and a certain thickness; but for materials with a surface and appearance that are not ideal, for example; for very thin and soft materials, if a photoelectric sensor or a travel switch is used to send a material arrival signal, the signal given will have a large deviation due to the irregular and uneven surface of the material, resulting in poor adsorption effect and affecting the subsequent paging effect.

[0046] like Figure 1 As shown, an adsorption paging method according to an embodiment of the present invention includes:

[0047] S100, obtaining the air pressure value in the air distribution valve in real time.

[0048] Exemplarily, the air distribution valve is connected to the corresponding suction cups in the suction cup group through multiple air pipes to provide adsorption force to the suction cups under the action of the air distribution valve. After the material comes into contact with the suction cup, the air pressure in the air distribution valve will change. The pressure sensor can be used to monitor the air pressure value of the air distribution valve in real time, thereby obtaining the real-time air pressure value of the air distribution valve for subsequent comparison with the first preset air pressure threshold value and the second preset air pressure threshold value.

[0049] In practical applications, the pressure signal detected by the pressure sensor is fed back to the A / D conversion card of the PLC controller and converted into a digital value by the A / D conversion card. Different vacuum degrees correspond to different values. For example: the pressure measurement range of the pressure sensor is: -100~+100kPa, and the corresponding output voltage is 1-5V; when working, the value is transmitted to the PLC controller A / D conversion card through the converted voltage signal and converted into a digital signal that can be processed by the PLC controller.

[0050] S200, comparing the air pressure value with a first preset air pressure threshold value, and controlling the lifting of the storage platform according to the first comparison result.

[0051] Exemplarily, the first preset air pressure threshold is pre-set so that after the detected air pressure value reaches the first preset air pressure threshold, the controller controls the storage platform to stop rising. At this time, the material on the top layer of the storage platform contacts the suction cup, which can effectively prevent the storage platform from continuing to rise and causing damage to the suction cup; if the detected air pressure value does not reach the first preset air pressure threshold, the controller controls the storage platform to continue to rise until the air pressure value in the air distribution valve is detected to reach the first preset air pressure threshold, and then the controller controls the storage platform to stop rising. In other words, by comparing the detected air pressure value in the air distribution valve with the first preset air pressure threshold, the automatic lifting and lowering of the storage platform can be controlled according to the first comparison result, so that the materials stacked on the storage platform can be accurately transferred to the position where the suction cup group can be sucked, without manual operation.

[0052] S300, comparing the air pressure value with a second preset air pressure threshold value, and controlling the suction cup group to adsorb the material on the uppermost layer of the storage table according to the second comparison result, and transferring the adsorbed material to a designated position; wherein the second preset air pressure threshold value is greater than the first preset air pressure threshold value.

[0053] Exemplarily, the second preset air pressure threshold is preset so that after the detected air pressure value reaches the second preset air pressure threshold, the controller directly controls the suction cup group to transfer the uppermost material to the designated position; if the detected air pressure value does not reach the second preset air pressure threshold, the controller first controls the suction cup group to move toward the storage table, and then adjusts the position of the suction cup group so that the suction cup group has a more stable adsorption effect on the uppermost material. In other words, by comparing the detected air pressure value with the second preset air pressure threshold, the movement of the suction cup group can be controlled according to the second comparison result, so that the adsorption position of the suction cup group can be adjusted to ensure a better adsorption effect on the material and avoid the material from falling during the transfer process, which affects the paging effect.

[0054] In this embodiment, the real-time air pressure value in the gas distribution valve is obtained, and the first preset air pressure threshold value and the second preset air pressure threshold value are pre-set, and then the air pressure value is compared with the first preset air pressure threshold value and the second preset air pressure threshold value, and then the lifting and lowering of the storage table is controlled according to the first comparison result of the air pressure value and the first preset air pressure threshold value, and then the storage table is adjusted to the position where the suction cup group can adsorb the uppermost material, and then the movement of the suction cup group of the suction cup group is controlled according to the second comparison of the air pressure value and the second preset air pressure threshold value, so that the adsorption position of the suction cup group can be adjusted to ensure a better adsorption effect on the material, and avoid the material from falling during the transfer process, which affects the paging effect. In other words, the adsorption paging method of this embodiment cleverly uses the real-time air pressure value in the gas distribution valve to compare with the first preset air pressure threshold value and the second preset air pressure threshold value respectively, and then controls the movement of the storage table and the suction cup group, completely abandoning the traditional position detection method of the photoelectric sensor (travel switch), greatly improving the accuracy of the detection; and also makes the operation more intuitive and simple in actual application, without the need to frequently adjust the sensor position and sensitivity.

[0055] In a possible embodiment, the steps of comparing the air pressure value with a first preset air pressure threshold and controlling the lifting and lowering of the storage platform according to the first comparison result include: setting the first preset air pressure threshold according to the material of the material; wherein the setting standard of the first preset air pressure threshold is that at this pressure value, one of the suction cups in the suction cup group contacts the topmost material on the storage platform; comparing the air pressure value with the first preset air pressure threshold; if the air pressure value reaches the first preset air pressure threshold, controlling the storage platform to stop rising so as to lift the materials stacked on the storage platform to a position where the suction cup group can adsorb; if the air pressure value does not reach the first preset air pressure threshold, controlling the storage platform to continue rising until the air pressure value reaches the first preset air pressure threshold, and then controlling the storage platform to stop rising.

[0056] In a possible embodiment, the air pressure value is compared with a second preset air pressure threshold, and according to the second comparison result, the suction cup group is controlled to adsorb the material on the top layer of the storage table, and the steps of transferring the adsorbed material to the designated position include: setting the second preset air pressure threshold according to the number of suction cups in the suction cup group that are in contact with the top layer of the material; wherein, the setting standard of the second preset air pressure threshold is that under this pressure value, the suction cup can effectively adsorb the material and will not adsorb the next material through the cover material; comparing the air pressure value with the second preset air pressure threshold; if the air pressure value does not reach the second preset air pressure threshold, controlling the suction cup group to descend toward the storage table so that multiple suction cups in the suction cup group are in adsorbent contact with the top layer of the material until the air pressure value reaches the second preset air pressure threshold, and controlling the suction cup group to transfer the adsorbed material to the designated position; if the air pressure value reaches the second preset air pressure threshold, controlling the suction cup group to transfer the adsorbed material to the designated position.

[0057] Please refer to Figures 2 to 7 The embodiment of the present application also provides an adsorption paging device, which is applied to the adsorption paging method of the above-mentioned embodiment. The adsorption paging device includes a frame 10, a storage table, a suction mechanism 30, a driving mechanism 70 and a sensing component. The frame 10 defines a material discharge area. The storage table is arranged in the material discharge area. The suction mechanism 30 includes a connecting beam 31 and at least two suction components 32. The connecting beam 31 spans the material discharge area and is located on the moving path of the storage table. All suction components 32 are connected to the connecting beam 31 at intervals along the length direction of the connecting beam 31, and the suction components 32 are used to adsorb materials on the storage table. The driving mechanism 70 is connected to the connecting beam 31 and the storage table to drive the connecting beam 31 to move back and forth along the first direction and drive the storage table to move back and forth along the second direction; wherein the first direction is perpendicular to the second direction. The sensing component includes an air distribution valve, an air pipe and a pressure sensor. One end of the air pipe is connected to the suction component 32, and the other end is connected to the air distribution valve. The pressure sensor is used to detect the pressure in the air distribution valve. The pressure sensor is electrically connected to the controller, and the controller is electrically connected to the drive mechanism 70.

[0058] The adsorption paging device based on the above technical features places the stacked materials on the storage table, and drives the connecting beam 31 to move along the first direction through the driving mechanism 70, so as to drive the suction component 32 to move to the top of the storage table and suspend, and then drives the storage table to move along the second direction, so that the storage table is constantly close to the suction component 32, so that the suction component 32 absorbs the uppermost material, and then continues to drive the connecting beam 31 to move, so as to move the absorbed material away from the storage table, and alternately absorbs the materials stacked on the storage table, so as to achieve the paging of the materials. In other words, the upper suction paging structure is simple, the degree of automation is high, it can effectively avoid the phenomenon of double-sheeting, and has a good paging effect.

[0059] Exemplarily, the suction component 32 is used to absorb the materials stacked on the storage table, and as the storage table continues to rise, the stacked materials are paging. In addition, the suction component 32 can specifically adopt the following structure, or can adopt the components that can achieve absorption in the prior art, which is not limited.

[0060] Exemplarily, the air distribution valve is used to connect the suction component 32 through the air pipe to provide the suction force required for the suction nozzle 323 to suck, and the air pressure value of the air distribution valve is different in different states. For example: two air pressure thresholds are pre-set on the controller, namely the first preset air pressure threshold and the second preset air pressure threshold. After the pressure in the air distribution valve reaches the first preset air pressure threshold pre-set on the controller and is detected by the pressure sensor, the controller controls the drive mechanism 70 to stop the storage table from rising. At this time, the suction component 32 partially absorbs the material on the top layer, but does not completely absorb it. After the suction component 32 is adjusted downward to completely absorb the material, the pressure in the air distribution valve reaches the second preset air pressure threshold and is detected by the pressure sensor. The controller controls the drive mechanism 70 to drive the connecting beam 31 to move back and forth in the first direction, thereby conveying the absorbed material forward, thereby ensuring that the material is more firmly adsorbed and avoiding falling during the transfer process, which affects normal paging.

[0061] In a possible embodiment, the suction assembly 32 includes a first linear motion member 321, a fixed frame 322 and a plurality of suction nozzles 323. The first linear motion member 321 is fixedly connected to the crossbeam and electrically connected to the first linear motion member 321. The fixed frame 322 is connected to the first linear motion member 321 to drive the fixed frame 322 to approach or move away from the storage table along a first direction. All suction nozzles 323 are distributed on the fixed frame 322 along the center of the fixed frame 322.

[0062] Exemplarily, after the storage platform rises to the position contacted by the suction nozzle 323, the suction nozzle 323 is blocked by the material, and the pressure in the gas distribution valve increases. At this time, the pressure sensor detects the pressure in the gas distribution valve. When the detected pressure value reaches the first preset air pressure threshold on the controller, the controller controls the storage platform to stop rising. At this time, the pressure value in the gas distribution valve has not reached the second preset air pressure threshold. The controller controls the first linear motion member 321 to drive the fixed frame 322 to approach the storage platform, so as to drive the suction nozzle 323 connected to the fixed frame 322 to move, thereby ensuring that all the suction nozzles 323 are in contact with the material and sucked tightly. After the pressure in the gas distribution valve reaches the second preset air pressure threshold, the controller controls the driving mechanism 70 to drive the connecting beam 31 to move back and forth in the first direction, so as to drive the material adsorbed by the suction nozzle 323 to be transported, thereby completing the automatic adsorption of the material. The structure is simple, can effectively avoid the phenomenon of double-sheeting, and has a good paging effect.

[0063] In a possible embodiment, the driving mechanism 70 includes a first driving component 71 and a second driving component 72. The first driving component 71 is used to drive the connecting beam 31 to move back and forth along a first direction to drive the suction component 32 to transport the adsorbed material. The second driving component 72 is used to drive the storage table to move back and forth along a second direction to make the material placed on the storage table close to the suction component 32.

[0064] In a possible implementation, the first drive assembly 71 includes a second linear motion member and a slide plate. The second linear motion mounting member is on the outer wall of the frame 10. The slide plate is slidably connected to the second linear motion member. The end of the connecting beam 31 is connected to the slide plate.

[0065] The second linear motion member drives the slide plate to move, so as to drive the connecting beam 31 to move in the first direction, until the suction assembly 32 is driven to move directly above the storage table, and then the second linear motion member stops driving the connecting beam 31 to move. At this time, as the storage table continues to rise, the suction assembly 32 contacts and absorbs the material on the top layer, and then the second linear unit starts to drive the connecting beam 31 to move away from the storage table, and then the absorbed material is transported forward, and the above actions are repeated repeatedly until the stacked materials are completely paginated. In other words, the above second linear motion member is used to drive the slide plate to move, so as to drive the connecting beam 31 to move. In this regard, the second linear motion member can be a driving member in the prior art, and this is not limited.

[0066] In a possible embodiment, the second drive assembly 72 includes a servo motor 726 and a transmission rod 721, the servo motor 726 is fixed on the frame 10, and the output shaft of the servo motor 726 is provided with a driving wheel 727, the transmission rod 721 is rotatably connected to the frame 10, and the two ends of the transmission rod 721 are respectively provided with a first transmission wheel 728 and a second transmission wheel 722, a synchronous belt is connected between the first transmission wheel 728 and the driving wheel 727, and the upper part of the outer wall of the frame 10 is provided with a third transmission wheel 723 located on the same side as the second transmission wheel 722, a transmission chain is connected between the third transmission wheel 723 and the second transmission wheel 722, and the storage table is connected to the transmission chain at one end close to the transmission chain.

[0067] Exemplarily, after the stacked materials are placed on the storage table, it is necessary to gradually drive the storage table to move continuously toward the suction component 32 so that the suction component 32 can suck the stacked materials on the storage table in turn. During this process, the servo motor 726 drives the driving wheel 727 to rotate, so as to drive the first conduction wheel to rotate, and then drive the transmission rod 721 to rotate. Since the other end of the transmission rod 721 is provided with a second transmission wheel 722, the outer wall of the frame 10 is provided with a third transmission wheel 723, and a transmission chain is connected between the third transmission wheel 723 and the second transmission wheel 722, and the transmission chain is connected to one end of the storage table, so that the storage table is driven to move upward, thereby ensuring that the suction component 32 can suck the materials on the storage table. The structure is simple and the operation is convenient, and there is no need to manually control the lifting and lowering of the storage table.

[0068] In a possible embodiment, it further includes guide rods 724 disposed on the two outer walls of the frame 10, and a slider 725 is slidably connected to the guide rods 724, and the slider 725 is connected to the end of the storage platform that passes through the frame 10. That is, when the servo motor 726 drives the driving wheel 727 to rotate to drive the synchronous belt to pull the storage platform 20 to move up and down, the slider 725 slides along the extension direction of the guide rod 724, thereby ensuring that the storage platform 20 only moves in a predetermined direction without left and right deviations, which is conducive to improving the accuracy of feeding.

[0069] In a possible embodiment, the suction assembly 32 further includes a clamp 324, which is clamped and connected to the fixed frame 322, and a mounting portion 324a is extended outwardly from one side of the clamp 324 away from the fixed frame 322, and the suction nozzle 323 is mounted on the mounting portion 324a, and the suction end of the suction nozzle 323 passes through the mounting portion 324a. In this way, by mounting the suction nozzle 323 on the mounting portion 324a, and then clamping the clamp 324 on the fixed frame 322, the suction nozzle 323 can be installed. When the position of the suction nozzle 323 needs to be adjusted, it is only necessary to adjust the clamping position of the clamp 324 on the fixed frame 322, which can be used to clamp materials of different sizes and has a wider applicability.

[0070] In a possible embodiment, the surface of the material placing table 20 for placing materials is provided with a material stopper 60. Thus, by providing a material stopper on the upper surface of the material placing table 20, the stacked materials are blocked by the material stopper 60, and can be stacked on the material placing table in an orderly manner, which is convenient for subsequent paging operations.

[0071] In a possible implementation, the upper suction paging device further includes a conveying mechanism 40, which is disposed at one end of the frame 10 away from the material placement table 20 and is used to convey the paginated material. It should be noted that the conveying assembly is mainly used to convey the paginated material forward, and its specific structure can be referred to the prior art, and no further elaboration will be given.

[0072] In a possible embodiment, the upper suction device further includes a material receiving mechanism 50, which is disposed at the discharge end of the conveying mechanism 40 and is used to receive the paginated materials.
