Description

Technical Field

[0001] The utility model relates to the field of filling, in particular to a filling machine with a filling bag and a cover detection function. Background Art

[0002] Spout bags are very popular as a packaging bag that can be sealed at any time. The filling and sealing of spout bags have always been a concern of people. Large-scale production enterprises use customized integrated filling and capping intelligent equipment production lines due to their large output, which have high work efficiency. However, for small enterprises or individual processors, the filling equipment cost of large production lines is relatively high, so most of them use manually controlled machine filling. Workers open the packaging bag and place it on the filling machine, and align the bag opening with the bottom of the filling machine's funnel for filling. After filling, the worker screws the lid onto the spout of the spout bag to seal it. This method of manually controlled filling and manually screwing the lid to seal is inefficient, and manual screwing of the lid cannot guarantee the tightness of the lid, which may cause leakage of the product in the bag.

[0003] A Chinese patent (authorization announcement number: CN221024337U) discloses an automatic capping filling machine for a spout bag, comprising: a machine platform, having a table for carrying filling bags and other components; a rotating unit, rotatably mounted on the machine platform, comprising a turntable and a first driving motor driving the turntable to rotate, wherein a bag clamping spring clamp for clamping the filling bag is arranged on the turntable along the circumference of the outer edge of the turntable; an opening unit, which can be mounted above the table surface so as to reciprocate up and down relative to the table surface, and has a function of inserting the filling bag through the spout; An internal blowing device is used to deliver gas to the filling bag to expand the deflated filling bag, and the air supply end of the blowing device is connected to the air supply device; a filling funnel is arranged above the table top, and has a funnel for filling, and the position of the funnel tube of the funnel corresponds to the position of the spout of the filling bag below the funnel; a cap screwing robot is arranged above the table top, and has a mechanical claw and a mechanical arm, wherein the mechanical claw is used to grab and screw the lid, and the mechanical arm is used to drive the mechanical claw to move vertically or horizontally relative to the table top.

[0004] The above patent solves the problem of low filling efficiency of spout bags used by small enterprises or individual processors. However, in actual use, if the staff forgets to put the filling bag and the lid, the normal operation of the machine will cause the filling funnel to fill the position without the filling bag, and the capping robot will screw in vain. Both of these situations will cause the filled product to spill on the machine, which not only causes waste, but also requires shutdown for cleaning, affecting work efficiency. Therefore, it is necessary to provide a filling machine that can detect whether the filling bag and the lid are in place. Utility Model Content

[0044] A schematic diagram of a filling machine with a filling bag and lid detection function in an embodiment of the present application, the filling machine with a filling bag and lid detection function provided by the present application comprises a machine platform 100 and a turntable 200 mounted on the machine platform 100, an air blowing device 300, a filling funnel 400, a capping robot 500, a detection device and a PLC controller 700, wherein the turntable 200 is mounted in the middle position above the machine platform 100, the air blowing device 300, the filling funnel 400 and the capping robot 500 are arranged on the machine platform 100 in a circumferential direction around the turntable 200, and the turntable 200 is used to carry the bag 10 and the lid 20 and convey the filling bag 10 and the lid 20. The bag 10 and the cover 20 arrive at each workstation, the blowing device 300 is used to blow up the filling bag 10 to facilitate subsequent filling, the filling funnel 400 is used to fill the product into the filling bag 10, and the capping robot 500 is used to screw the cover 20 onto the filling bag 10 for sealing. The PLC controller 700 is respectively controlled and connected with the turntable 200, the blowing device 300, the filling funnel 400, and the capping robot 500. A control strategy is set in the PLC controller 700. The PLC controller 700 controls the opening and closing of the filling funnel 400 and the filling amount, and controls the start and stop of the capping robot 500 according to the above control strategy. The detection device is communicatively connected to the PLC controller 700. The detection device is used to detect whether a filling bag 10 and a lid 20 are placed on the workstation corresponding to the detection device on the turntable 200 and send the detection result to the PLC controller 700. The PLC controller 700 controls the filling funnel 400 to fill the above-mentioned workstation according to the obtained detection result.

[0045] Specifically, see Figure 1 The machine 100 is horizontally arranged and has a table 110. A through hole is arranged in the middle of the table 110 and passes through the table 110 in a vertical direction. Figure 4 As shown, a first driving device 220 is installed below the turntable 200 to drive the turntable to rotate. Figure 3 As shown, the first driving device 220 is fixedly installed below the table 110, and the free end of the rotating shaft of the first driving device 220 passes through the through hole on the table 110 and is fixedly connected to the turntable 200. The PLC controller 700 is connected to the first driving device 220 for control, and the PLC controller 700 controls the rotation, stop and rotation speed of the turntable 200 by controlling the first driving device 220.

[0046] See also Figure 2 A lid positioning piece 211 and a bag clamping spring clamp 212 are circumferentially arranged on the turntable 200. The lid positioning piece 211 is used to support the lid 20 to prevent the lid 20 from sliding horizontally. The bag clamping spring clamp 212 is used to clamp the filling bag 10. The spout of the filling bag 10 is clamped in the bag clamping spring clamp 212.

[0047] See also Figure 3-Figure 4The blowing device 300 includes a blowing pipe 310 that can move back and forth up and down relative to the table 110, a second driving device 320 for driving the blowing pipe 310 to move back and forth up and down relative to the table 110, and a gas supply device 330 for supplying gas to the blowing pipe 310. The blowing device 300 is used to deliver gas to the filling bag 10 to open the compressed filling bag 10. The PLC controller 700 is connected to the switch control of the second driving device 320 and the gas supply device 330. The PLC controller 700 controls the gas outlet of the blowing pipe 310 to extend into the filling bag 10 or move out of the filling bag 10 by controlling the second driving device 320. The PLC controller 700 controls the start interval time and the blowing time of the gas supply device 330 by controlling the switch of the gas supply device 330.

[0048] See also Figure 4-Figure 6 The detection device includes a first optical fiber amplifier 610 and a second optical fiber amplifier 620. Figure 6 As shown, the first optical fiber amplifier 610 is installed above the lid positioning member 211. The first optical fiber amplifier 610 detects whether the bag clamp spring clamp 212 is loaded with a filling bag 10 by diffuse reflection. Figure 4 As shown, the second optical fiber amplifier 620 is installed next to the bag spring clamp 212. The second optical fiber amplifier 620 detects whether the cover 20 is installed on the cover positioning member 211 through diffuse reflection. The first optical fiber amplifier 610 and the second optical fiber amplifier 620 are both connected to the PLC controller 700 for communication and send the detection results to the PLC controller 700.

[0049] Furthermore, in addition to the optical fiber amplifier, the detection device can also use a capacitive switch. If the lid positioning member 211 and the bag clamping spring clamp 212 are both made of metal materials, the detection device can also be a metal induction switch. In summary, as long as the device can detect whether the filling bag 10 and the lid 20 are in place, it can be the detection device in the utility model, and it is meaningless to list them here.

[0050] In addition, the detection device can be installed on the support frame of the blowing device 300, or can be installed on the machine 100 through a bracket alone, or installed on other components before the filling process, and the position can be designed according to the actual size and space of the equipment.

[0051] When the detection result received by the PLC controller 700 is any of the following three situations: there is no filling bag 10, no lid 20, or there is neither lid 20 nor filling bag 10 at the workstation corresponding to the detection device, the PLC controller 700 controls the filling funnel 400 to cancel the filling work at the workstation.

[0052] See also Figure 7-Figure 8The filling funnel 400 can be installed above the table 110 so as to be movable up and down relative to the table 110. Figure 8 As shown, the filling funnel 400 is provided with a third driving device 410 for driving the filling funnel 400 to move up and down relative to the table 110. When the filling bag 10 moves below the filling funnel 400, the filling funnel 400 moves downward, so that the discharge pipe of the filling funnel 400 extends into the filling bag 10. When the filling is completed, the discharge pipe of the filling funnel 400 moves upward and resets.

[0053] See also Figure 8-Figure 9 A metering funnel 800 for weighing materials is provided above the filling funnel 400, see Figure 8-10 A weighing sensor is fixedly mounted on the frame 100, and the metering funnel 800 is mounted on the weighing sensor. The weighing sensor is in communication with the PLC controller 700. The weighing sensor is used to weigh the material in the metering funnel 800 and transmit the weight data of the metering funnel 800 to the PLC controller 700. An openable and closable baffle 810 is arranged on the lower opening of the metering funnel 800. A fourth driving device 820 for controlling the opening and closing of the baffle 810 is connected to the baffle 810. The PLC controller 700 is in control connection with the fourth driving device 820. The PLC controller 700 controls the opening and closing of the baffle 810 by controlling the fourth driving device 820.

[0054] See also Fig.10 A storage funnel 900 is provided above the metering funnel 800 for feeding materials into the metering funnel 800. Figure 8 and Fig.11 The storage funnel 900 is fixedly mounted on the frame 100, and a flow limiting plate 910 capable of adjusting the material flow rate is provided at the bottom of the storage funnel 900. Fig.12A discharge port is arranged at the bottom of the storage funnel 900, and the discharge port is arranged above the feed port of the metering funnel 800. The limiting plate 910 can be slidably installed on the storage funnel 900 along the edge of the discharge port. The limiting plate 910 is used to control the material lowering speed. The limiting plate 910 is connected to a fifth driving device 920 for driving the limiting plate 910 to slide. The PLC controller is connected to the fifth drive device 920. The PLC controller controls the opening and closing and the opening and closing degree of the limiting plate 910 by controlling the fifth drive device 920. The material flow rate is controlled by controlling the opening and closing degree of the limiting plate 910. When there is little material in the metering funnel 800, the limiting plate 910 can be opened to allow the material to flow quickly into the metering funnel 800. When the material in the metering funnel 800 is close to the set filling value, the limiting plate 910 slides to make the discharge port smaller. When the material in the metering funnel 800 reaches the set filling value, the limiting plate 910 closes the discharge port. The setting of the limiting plate 910 can reduce the material flow rate when the material in the metering funnel 800 is close to the set filling value. When the material in the metering funnel 800 reaches the set filling value, the limiting plate 910 can quickly close the discharge port to prevent too much material from flowing into the metering funnel 800 so that the material in the metering funnel 800 exceeds the set value.

The end of the claw 541 is provided with a striped convex ridge, which can increase the friction between the end of the claw 541 and the cover 20, so that the mechanical claw 510 can better grasp the cover 20 and effectively prevent the mechanical claw 510 from slipping when tightening the cover 20.

[0060] During use, the staff inserts the spout of the filling bag 10 to be filled into the bag clamp spring clamp 212, and places the lid 20 on the lid positioning piece 211; the PLC controller 700 sends a control instruction to the first drive device 220 according to the control strategy, and the first drive device 220 drives the turntable 200 to rotate after starting, and the filling bag 10 follows the turntable 200 to rotate under the blowing pipe 310, and the blowing device 300 blows air to the filling bag 10; the detection device detects whether the filling bag 10 is installed on the bag clamp spring clamp 212, detects whether the lid 20 is installed on the lid positioning piece 211, and sends the detection result to the PLC controller; the PLC controller 700 receives the detection result of the detection device and forms a control instruction according to the control strategy. When the detection result is that there is a lid and a filling bag 10, the PLC controller 700 forms a filling instruction and sends it to the fourth drive device 820, and controls the fourth drive device 820 to operate at the above-mentioned detection station When it reaches the bottom of the filling funnel 400, the baffle 810 is driven to open the lower end opening of the metering funnel 800 to fill the filling bag 10; when the detection result received by the PLC controller 700 is any of the three situations of no filling bag 10, no lid 20, and no lid 20 and filling bag 10, the PLC controller 700 generates a no filling instruction and sends it to the fourth drive device 820, and controls the fourth drive device 820 not to work when the above-mentioned detection station reaches the bottom of the filling funnel 400, and the baffle 810 continues to block the lower end opening of the metering funnel 800. At the same time, the PLC controller 700 controls the fifth drive device 920 not to open the flow limiting plate 910 when the above-mentioned detection station reaches the bottom of the filling funnel 400; if filling is to be carried out, the PLC control device controls the capping robot 500 to perform the capping work, and if filling is not to be carried out, the PLC control device controls the capping robot 500 not to perform the capping work.
