[0054] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0055] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0056] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0057] The following is combined with Figures 1 to 11 The embodiments of this utility model will be described below. It should be understood that the following description is merely an illustrative embodiment of this utility model and does not constitute any limitation on this utility model.

[0058] To more clearly illustrate the orientation of each component in the nozzle detection device provided in this embodiment of the invention, combined with... Figures 1 to 11 Establish a three-dimensional coordinate system XYZ, with the X-axis as the first direction, the Y-axis as the second direction, and the Z-axis as the third direction; where the positive direction of the X-axis is the first positive direction, and the negative direction of the X-axis is the first negative direction; the positive direction of the Y-axis is the second positive direction, and the negative direction of the Y-axis is the second negative direction; the positive direction of the Z-axis is the third positive direction, and the negative direction of the Z-axis is the third negative direction.

[0059] The soft bag 1 typically includes a soft bag body 11 and a cover 12. The soft bag body 11 is provided with a bag opening 13, and the cover 12 is detachably provided on the bag opening 13. For example, the cover 12 can be screwed onto the bag opening 13 by means of a threaded connection.

[0060] An embodiment of this utility model provides a soft bag filling device, which includes a capping device 100, a clamping device 200, a filling device 300, and a control device 400.

[0061] The capping device 100 can tighten the cap 12 to the bag opening 13. The capping device 100 includes a three-jaw cap gripper 110 and a rotary motor 120. The capping device 100 can be a magnetic clutch capping head. The three-jaw cap gripper 110 forms a gripping area that can clamp or release the cap. When the control device 400 issues a capping command, the three-jaw cap gripper 110 aligns with the cap 12 so that the cap 12 is located in the gripping area. Then, it clamps the cap 12 and moves it to the bag opening 13. Then, the rotary motor 120 is started to tighten the cap 12 to the bag opening 13.

[0062] The clamping device 200 has a first clamping arm 210 and a second clamping arm 220, which clamp the soft bag body 11 by clamping the bag opening 13. In this embodiment, the bag opening 13 has a clamping slot 14, and the first clamping arm 210 and the second clamping arm 220 can clamp into the clamping slot 14 to clamp the bag opening 13, thereby achieving clamping of the soft bag body 11. The structure is simple and the clamping is more stable.

[0063] The filling device 300 includes a filling nozzle 310 and a filling pump 320. The filling nozzle 310 is matched and corresponds to the bag opening 13. When filling is required, the liquid outlet of the filling nozzle 310 is inserted into the bag opening 13. The filling pump 320 connects the filling nozzle 310 with the liquid to be filled from the outside. Under the suction of the filling pump 320, the liquid to be filled from the outside (e.g., soy sauce or vinegar) will be poured from the filling nozzle 310 into the soft bag body 11.

[0064] The control device 400 is electrically connected to the capping device 100, the clamping device 200 and the filling device 300. It can control the capping device 100 to tighten the cap 12, control the clamping device 200 to clamp the bag opening 13 and control the filling device 300 to fill the soft bag 1.

[0065] When the bag opening 13 is placed between the first clamping arm 210 and the second clamping arm 220, the control device 400 controls the first clamping arm 210 and the second clamping arm 220 to move closer to each other to clamp the bag opening 13, thereby clamping the soft bag body 11.

[0066] Then, the control device 400 controls the filling pump 320 to start, filling the external liquid to be filled into the soft bag body 11 through the filling nozzle 310. In this embodiment, the control device 400...

[0067] It is understood that the soft bag filling equipment provided by this utility model, by setting a capping device 100 to tighten the cap 12 to the bag opening 13, setting a clamping device 200 to clamp the soft bag body 11, setting a filling device 300 to fill the liquid to be filled into the soft bag body 11, and also setting a control device 400 electrically connected to the capping device 100, the clamping device 200 and the filling device 300 to control the operation of the related devices, reduces the reliance on manual labor, has higher filling and sealing efficiency, is more convenient to operate, can be mass-produced, and can avoid the error problem of manual filling.

[0068] Specifically, in combination Figures 1 to 7 In order to make the structure of the clamping device 200 simpler and the operation more convenient, in some embodiments of the present invention, the clamping device 200 further includes a clamping base plate 230 and a clamping pusher 240.

[0069] The first clamping arm 210 and the second clamping arm 220 are arranged opposite to each other and are both hinged to the clamping base plate 230, forming a clamping area 250 and a clamping and pushing area 260.

[0070] The clamping pusher 240 is matched with the clamping push area 260. In this embodiment, the clamping pusher 240 includes a clamping cylinder 241 and a clamping pusher 242. The clamping pusher 242 is mounted on the telescopic rod 520 of the clamping cylinder 241. The clamping pusher 242 is matched with the clamping push area 260. The clamping cylinder 241 can drive the clamping pusher 242 to reciprocate in a first direction.

[0071] When the clamping pusher 240 slides in the first positive direction to the clamping push area 260 and abuts against the first clamping arm 210 and the second clamping arm 220, the first clamping arm 210 and the second clamping arm 220 located in the clamping push area 260 are spread apart by the clamping pusher 242 and move away from each other, while the first clamping arm 210 and the second clamping arm 220 located in the clamping area 250 are close to each other and are in a clamping state, thereby clamping the bag opening 13.

[0072] When the clamping pusher 240 slides in the first negative direction, the first clamping arm 210 and the second clamping arm 220 located in the clamping push area 260 can move closer to each other, so that the first clamping arm 210 and the second clamping arm 220 located in the clamping area 250 can move further apart from each other, thereby allowing the first clamping arm 210 and the second clamping arm 220 to release the bag opening 13, and the soft bag 1 can be taken out.

[0073] Furthermore, combined Figures 1 to 7 In some embodiments of this utility model, the clamping device 200 further includes an elastic element 270, which is disposed on one side of the clamping area 250.

[0074] The first end of the elastic element 270 is fixed to the first clamping arm 210, and the second end of the elastic element 270 is fixed to the second clamping arm 220.

[0075] After filling is complete, when the clamping pusher 242 retracts from the clamping area 250 in the first negative direction, the elastic element 270 can keep the first clamping arm 210 and the second clamping arm 220 in a clamping state, preventing gaps from appearing between the bag opening 13 and the first clamping arm 210 and the second clamping arm 220, thus preventing the soft bag 1 from falling off and improving the installability of the equipment. Of course, in this embodiment, the elastic element 270 can be an ordinary spring.

[0076] In addition, to improve the intelligence level of the device, in some embodiments of this utility model, the clamping device 200 also includes a clamping position sensor 280.

[0077] The clamping position sensor 280 is located on one side of the base plate and can detect the displacement of the first clamping arm 210 or the second clamping arm 220. The clamping position sensor 280 is electrically connected to the control device 400.

[0078] For example, in this embodiment, the clamping position sensor 280 can be installed on the clamping base plate 230 located on one side of the first clamping arm 210. By detecting the displacement of the first clamping arm 210 and feeding back relevant data to the control device 400, the control device 400 controls the action of the clamping cylinder 241 according to the displacement data of the first clamping arm 210.

[0079] Combination Figures 4 to 6 To further improve filling accuracy, in some embodiments of this invention, the device also includes a metering element 330, which is disposed between the filling nozzle 310 and the filling pump 320 and can measure the amount of liquid poured into the soft bag body 11. The metering element 330 can be a flow meter.

[0080] The metering element 330 is electrically connected to the control device 400. When the metering element 330 detects that the amount of liquid poured into the soft bag body 11 has reached a preset value, the control device 400 will stop the operation of the filling pump 320.

[0081] In addition, to further improve the accuracy of detecting the amount of liquid poured into the soft bag body 11, in some embodiments of this utility model, a weighing device can be set to weigh the soft bag body 11. The weighing device is electrically connected to the control device 400. When the weighing device detects that the amount of liquid poured into the soft bag body 11 has reached a preset weight value, the control device 400 will stop the operation of the filling pump 320. The weighing device can be an electronic scale.

[0082] Combination Figures 1 to 9 In some embodiments of this utility model, the filling nozzle 310 includes a filling valve body 311, a filling valve core 312, and a filling valve nozzle 313.

[0083] The filling valve 313 is located at the end of the filling valve body 311 and corresponds to the bag opening 13. After the external liquid is drawn by the filling pump 320, it is filled into the soft bag body 11 through the filling valve 313.

[0084] The filling valve core 312 is slidably connected to the filling valve body 311 to form a vacuum valve. Before filling the soft bag 1 with liquid, the air inside the soft bag 1 can be drawn out first, so that a vacuum can be formed inside the soft bag 1, making filling more convenient, filling effect better, and preventing the liquid inside the soft bag 1 from overflowing during filling.

[0085] The filling valve body 311 is also provided with a filling inlet 3111, which is connected to the filling pump 320.

[0086] Combination Figure 8 In order to further prevent liquid from overflowing from the soft bag 1 during filling, in some embodiments of this utility model, a filling sealing ring 3131 is also provided outside the filling valve nozzle 313.

[0087] When the filling valve 313 comes into contact with the bag opening 13, the filling sealing ring 3131 seals against the inner wall of the bag opening 13.

[0088] Combination Figure 6 In some embodiments of this utility model, the soft bag filling equipment also includes a feeding device 500 and a support frame 600. The support frame 600 is fixed to the ground, and the feeding device 500, the capping device 100, the clamping device 200, the filling device 300 and the control device 400 can all be set on the support frame 600.

[0089] The feeding device 500 includes a support platform 510 and a telescopic rod 520. The first end of the support platform 510 is hinged to the support frame 600, the first end of the telescopic rod 520 is hinged to the support frame 600, and the second end of the telescopic rod 520 is hinged to the second end of the support platform 510.

[0090] The telescopic rod 520 is electrically connected to the control device 400. After the filling device 300 finishes filling the soft bag 1, the control device 400 will control the telescopic rod 520 to retract. The second end of the telescopic rod 520 will move in the third negative direction, so that the soft bag 1 will descend in the third negative direction and flow into the conveyor line, thereby improving the efficiency of material feeding.

[0091] Of course, in some embodiments of this utility model, the support platform 510 is also provided with multiple rollers 511, so that the friction between the soft bag 1 and the support platform 510 is smaller, and the soft bag 1 is easier to descend onto the conveyor line under the action of gravity.

[0092] Combination Figure 10 In some embodiments of this utility model, the soft bag filling equipment further includes a guiding device 700, which includes a first guiding shaft 710, a second guiding shaft 720, a first guiding plate 730, a second guiding plate 740, and a third guiding plate 750.

[0093] The first guide shaft 710 is horizontally (i.e., in the second direction where the Y-axis is located) and parallel to the support frame 600, and the first guide plate 730 is slidably connected to the first guide shaft 710.

[0094] The second guide shaft 720 is longitudinally (i.e., the third direction where the Z-axis is located) disposed on the first guide plate 730, and the second guide plate 740 and the third guide plate 750 are slidably connected to the second guide shaft 720.

[0095] The filling nozzle 310 is located on the second guide plate 740, and the capping device 100 is located on the third guide plate 750.

[0096] After the filling device 300 has finished filling the soft bag 1 with liquid, the capping device 100 can slide laterally (i.e., the second direction where the Y-axis is located) to the upper end of the bag opening 13, and the three-claw capping device 110 can be inserted into the bag opening 13 longitudinally (i.e., the third direction where the Z-axis is located). The cap body 12 is tightened by rotating the motor 120, which improves the efficiency of capping and makes the operation of the equipment more convenient.

[0097] In this specification, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
