If the defective packaging boxes continue to be conveyed forward, it may cause slight or severe extrusion of the defective packaging boxes between the fifth wheel and the sixth wheel. If the defective packaging boxes are slightly extruded by the fifth wheel and the sixth wheel, it will bring quality risks. When the operator discovers the defective packaging boxes, it takes a relatively long time to intercept the defective packaging boxes, which will increase the working intensity of the operator. If the fifth wheel and the sixth wheel severely extrude the defective packaging boxes, it will cause damage to the fifth wheel and the sixth wheel, increase the maintenance cost of the fifth wheel and the sixth wheel, and at the same time reduce the production efficiency. Summary of the Invention

[0007] A second detection mechanism, which is arranged on the interception plate and is used to cooperate with the first detection mechanism for detection;

[0008] When the defective packaging box is pushed out from the fifth wheel, the interception plate can rotate under the push of the defective packaging box, so as to drive the second detection mechanism to move relative to the first detection mechanism and trigger the first detection mechanism. After rotation, an outlet for discharging the defective packaging box is formed between the interception plate and the sixth wheel.

[0009] For the above-mentioned defective packaging box interception device, when a defective packaging box is pushed out from the fifth wheel, due to the change in the shape and size of the defective packaging box, the defective packaging box will squeeze the interception plate, causing the interception plate to rotate. Since the second detection mechanism is provided on the interception plate, the interception plate will drive the second detection mechanism to move relative to the first detection mechanism to trigger the first detection mechanism. The packaging machine can stop according to the detection information of the first detection mechanism. At the same time, after the interception plate rotates, it can intercept the defective packaging box. In this way, with the cooperation of the first detection mechanism, the second detection mechanism and the interception plate, defective packaging boxes can be detected and intercepted, preventing the defective packaging boxes on the fifth wheel from flowing into the next process, reducing the interception time of defective packaging boxes, and improving the production quality of packaging boxes.

[0021] In the above packaging machine, when a defective packaging box is pushed out from the fifth wheel, due to the change in the shape and size of the defective packaging box, the defective packaging box will squeeze the interception plate, causing the interception plate to rotate. Since the second detection mechanism is arranged on the interception plate, the interception plate will drive the second detection mechanism to move relative to the first detection mechanism to trigger the first detection mechanism. The packaging machine can stop according to the detection information of the first detection mechanism. At the same time, after the interception plate rotates, it can intercept the defective packaging box. In this way, with the cooperation of the first detection mechanism, the second detection mechanism and the interception plate, the defective packaging box can be detected and intercepted, preventing the defective packaging box on the fifth wheel from flowing into the next process, reducing the interception time of the defective packaging box, and improving the production quality of the packaging box.

[0045] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0046] See also Figure 1 The packaging machine provided in one embodiment of the present application has a model of ZB45. The packaging machine includes a fifth wheel 20 and a sixth wheel 30.

[0047] See also Figure 1, the fifth wheel 20 includes a first wheel body 21, a first die box 22, a folding plate 23, and a pushing mechanism 24. The first wheel body 21 is rotatably arranged. A plurality of first die boxes 22 are provided. The plurality of first die boxes 22 are arranged on the outer peripheral surface of the first wheel body 21 and are spaced along the circumferential direction of the first wheel body 21. The folding plate 23 is arranged on the sixth wheel 30 and extends to the outer peripheral surface of the first wheel body 21. The folding plate 23 is used for folding the packaging box. The pushing mechanism 24 is arranged on the first wheel body 21. The pushing mechanism 24 is used for pushing the packaging box in the first die box 22 onto the sixth wheel 30.

[0048] Refer to Figure 1 , the sixth wheel 30 includes a second wheel body 31 and a second die box 32. The second wheel body 31 is rotatably arranged. A plurality of second die boxes 32 are provided. The plurality of die boxes are arranged on the outer peripheral surface of the second wheel body 31 and are spaced along the circumferential direction of the second wheel body 31.

[0049] During operation, the packaging box on the fifth wheel 20 is located in the first die box 22. The packaging box rotates and folds under the action of the folding plate 23 and reaches the socket of the fifth wheel 20. Then, the pushing mechanism 24 pushes the packaging box in the first die box 22 into the second die box 32. The rotation of the sixth wheel 30 drives the packaging box to continue to be conveyed to the next process.

[0050] During the operation process, there will be defective packaging boxes on the fifth wheel 20. If the defective packaging boxes continue to be conveyed forward, the fifth wheel 20 and the sixth wheel 30 will slightly squeeze or severely squeeze the defective packaging boxes. If the defective packaging boxes are slightly squeezed by the fifth wheel 20 and the sixth wheel 30, it will bring quality risks. When the operator discovers the defective packaging boxes, it takes a lot of time to intercept the defective packaging boxes, which will increase the working intensity of the operator. If the fifth wheel 20 and the sixth wheel 30 severely squeeze the defective packaging boxes, it will cause damage to the fifth wheel 20 and the sixth wheel 30, increase the maintenance cost of the fifth wheel 20 and the sixth wheel 30, and at the same time reduce the production efficiency.

[0051] To solve the above problems, refer to Figure 1 , the packaging machine according to an embodiment of the present application further includes a defective packaging box interception device 10. The defective packaging box interception device 10 is arranged between the fifth wheel 20 and the sixth wheel 30. The defective packaging box interception device 10 is used for detecting and intercepting the packaging box pushed from the fifth wheel 20 to the sixth wheel 30. By setting the defective packaging box interception device 10, the defective packaging box interception device 10 can timely detect and intercept the defective packaging boxes, prevent the defective packaging boxes from flowing to the next process, reduce the interception time of the defective packaging boxes, and improve the production quality of the packaging boxes.

[0052] It should be noted that the defective packaging box refers to a deformed packaging box, for example, the shape and size of the packaging box have changed.

[0053] In one embodiment, refer toFigure 1 and Figure 3 For the defective packaging box interception device 10, it includes a first detection mechanism 11, a second detection mechanism 12 and an interception plate 13. The first detection mechanism 11 is arranged on the fifth wheel 20 or the sixth wheel 30. Optionally, the first detection mechanism 11 is arranged on the folding plate 23 of the fifth wheel 20 through an adapter bracket 14. The second detection mechanism 12 is arranged on the interception plate 13. The interception plate 13 is rotatably arranged between the fifth wheel 20 and the sixth wheel 30. When a defective packaging box is pushed from the fifth wheel 20 to the sixth wheel 30, the interception plate 13 can rotate under the push of the defective packaging box so that the second detection mechanism 12 moves relative to the first detection mechanism 11 and triggers the first detection mechanism 11. An outlet for discharging the defective packaging box is formed between the rotated interception plate 13 and the sixth wheel 30.

[0054] When the defective packaging box is pushed out from the fifth wheel 20, due to the change in the shape and size of the defective packaging box, the defective packaging box will squeeze the interception plate 13, causing the interception plate 13 to rotate. Since the second detection mechanism 12 is arranged on the interception plate 13, the interception plate 13 will drive the second detection mechanism 12 to move relative to the first detection mechanism 11 to trigger the first detection mechanism 11. The packaging machine can stop according to the detection information of the first detection mechanism 11. At the same time, after the interception plate 13 rotates, it can intercept the defective packaging box. In this way, with the cooperation of the first detection mechanism 11, the second detection mechanism 12 and the interception plate 13, the defective packaging box can be detected and intercepted, preventing the defective packaging box on the fifth wheel 20 from flowing into the next process, reducing the interception time of the defective packaging box, and improving the production quality of the packaging box.

[0055] In one embodiment, the first detection mechanism 11 is a proximity switch, and the second detection mechanism 12 is a detection rod. Optionally, the proximity switch and the detection rod are on the same center of the circle, and the relative distance between the proximity switch and the detection rod is 1 mm to 3 mm.

[0056] Under normal circumstances, the proximity switch and the detection rod are arranged opposite to each other. When the defective packaging box is pushed out from the fifth wheel 20, the defective packaging box squeezes the interception plate 13, causing the interception plate 13 to rotate. During the rotation of the interception plate 13, the detection rod is driven to move synchronously. Since the detection rod has a displacement relative to the proximity switch, this will trigger the detection signal of the proximity switch.

[0057] Specifically, the adapter bracket 14 is provided with a threaded hole, and the proximity switch is arranged in the threaded hole. A nut is used to lock the proximity switch on the adapter bracket 14.

[0058] Specifically, the interception plate 13 is provided with a threaded hole, and the detection rod is arranged in the threaded hole. A nut is used to lock the detection rod on the interception plate 13.

[0059] Of course, in other embodiments, one of the first detection mechanism 11 and the second detection mechanism 12 is a transmitter, and the other of the first detection mechanism 11 and the second detection mechanism 12 is a receiver. Under normal circumstances, the transmitter and the receiver are arranged opposite to each other, and the receiver can receive the signal emitted by the transmitter. When a defective packaging box is pushed out from the fifth wheel 20, the defective packaging box will squeeze the intercepting plate 13, causing the intercepting plate 13 to rotate, and further driving the transmitter or the receiver to move, resulting in the receiver being unable to receive the signal emitted by the transmitter. The packaging machine can stop according to the signal of the receiver.

[0060] In one embodiment, referring to Figure 4 、 Figure 5 and Figure 6 , the defective packaging box intercepting device 10 further includes a first limiting structure 1311 and a second limiting structure 1511.

[0061] The first limiting structure 1311 can be in limiting cooperation with the second limiting structure 1511 to limit the rotation of the intercepting plate 13. With this arrangement, it is possible to prevent the intercepting plate 13 from rotating accidentally under external force and triggering the first detection mechanism 11, thereby improving the reliability of detection.

[0062] When the defective packaging box pushes the intercepting plate 13, the first limiting structure 1311 is separated from the second limiting structure 1511. When the defective packaging box is pushed out from the fifth wheel 20, the defective packaging box squeezes the intercepting plate 13, and the intercepting plate 13 rotates against the acting force between the first limiting structure 1311 and the second limiting structure 1511 to intercept the defective packaging box.

[0063] In one embodiment, referring to Figure 1 and Figure 4 , the defective packaging box intercepting device 10 further includes a first positioning plate 15. The first positioning plate 15 is arranged between the fifth wheel 20 and the sixth wheel 30, and the first positioning plate 15 and the intercepting plate 13 are arranged on the same side of the fifth wheel 20 and are rotatably connected.

[0064] It should be noted that under normal circumstances, the first positioning plate 15 and the intercepting plate 13 are arranged side by side.

[0065] Furthermore, the first limiting structure 1311 is arranged on the intercepting plate 13, and the second limiting structure 1511 is arranged on the first positioning plate 15. The first limiting structure 1311 and the second limiting structure 1511 are in limiting cooperation to limit the rotation of the intercepting plate 13 relative to the first positioning plate 15. When the defective packaging box is pushed out from the fifth wheel 20, the defective packaging box will squeeze the intercepting plate 13, and the intercepting plate 13 rotates against the acting force between the first limiting structure 1311 and the second limiting structure 1511.

[0066] In one embodiment, referring to Figure 4, the defective packaging box intercepting device 10 further includes a rotating seat 131 and a first fixing seat 151. The rotating seat 131 is provided on the intercepting plate 13. Optionally, the rotating seat 131 is fixed to the intercepting plate 13 by screws. The first fixing seat 151 is provided on the first positioning plate 15. Optionally, the first fixing seat 151 is fixed to the first positioning plate 15 by screws. The rotating seat 131 is rotatably connected to the first fixing seat 151 so that the intercepting plate 13 can rotate relative to the first positioning plate 15. With the cooperation of the rotating seat 131 and the first fixing seat 151, the first positioning plate 15 and the intercepting plate 13 can be rotatably connected.

[0067] Further, referring to Figure 5 and Figure 6 , a first limiting structure 1311 is provided on the rotating seat 131, and a second limiting structure 1511 is provided on the first fixing seat 151. In this way, the rotating seat 131 provides a setting position for the first limiting structure 1311, and the first fixing seat 151 provides a setting position for the second limiting structure 1511, which can eliminate the complex design of setting the limiting structure at other positions and make the overall structure more concise and compact.

[0068] In one embodiment, referring to Figure 5 and Figure 6 , one of the first limiting structure 1311 and the second limiting structure 1511 includes a spring catch, and the other of the first limiting structure 1311 and the second limiting structure 1511 is provided with a limiting groove. Under normal circumstances, the catch in the spring catch is located in the limiting groove to limit the rotation of the intercepting plate 13. When the defective packaging box is pushed out from the fifth wheel 20, the defective packaging box presses the intercepting plate 13, the spring of the spring catch is compressed by the force, and the spring catch is separated from the limiting groove, so that the intercepting plate 13 can rotate under the extrusion of the defective packaging box.

[0069] Of course, in other embodiments, one of the first limiting structure 1311 and the second limiting structure 1511 includes a first magnetic attracting member, the other of the first limiting structure 1311 and the second limiting structure 1511 includes a second magnetic attracting member, and the first magnetic attracting member and the second magnetic attracting member are magnetically coupled to limit the rotation of the intercepting plate 13.

[0070] In one embodiment, referring to Figure 5 and Figure 6 , the defective packaging box intercepting device 10 further includes a rotating shaft 17. The rotating shaft 17 is provided on the first fixing seat 151, and the rotating seat 131 is provided on the rotating shaft 17. In this way, the rotating shaft 17 can be used to realize the rotational connection between the rotating seat 131 and the first fixing seat 151.

[0071] In one embodiment, referring to Figure 5 and Figure 6, the defective packaging box interception device 10 further includes a second fixing seat 152, and the second fixing seat 152 is arranged on the side of the rotating seat 131 away from the first fixing seat 151. The rotating shaft 17 is arranged between the first fixing seat 151 and the second fixing seat 152. One end of the rotating shaft 17 is rotatably connected to the first fixing seat 151, and the other end of the rotating shaft 17 is rotatably connected to the second fixing seat 152. Among them, the first fixing seat 151 and the rotating shaft 17 are in clearance fit, and the second fixing seat 152 and the rotating shaft 17 are connected through a bearing. In this way, the reliability of the rotation connection between the interception plate 13 and the first positioning plate 15 can be improved.

[0072] In one embodiment, one of the rotating seat 131 and the rotating shaft 17 is provided with a locking member 1312, and the locking member 1312 is in abutting cooperation with the other of the rotating seat 131 and the rotating shaft 1713. In this way, under the action of the locking member 1312, the rotating seat 131 can be fixedly connected to the rotating shaft 17.

[0073] Further, refer to Figure 5 and Figure 6 , the other of the rotating seat 131 and the rotating shaft 17 is arranged in the locking groove 171. Optionally, the locking groove 171 is arranged circumferentially around the rotating shaft 17. The locking member 1312 is arranged in the locking groove 171 and is in abutting cooperation with the groove wall of the locking groove 171. In this way, under the cooperation of the locking member 1312 and the locking groove 171, the axial movement of the rotating shaft 17 can be prevented, and the reliability of the connection between the rotating seat 131 and the rotating shaft 17 can be improved.

[0074] In one embodiment, refer to Figure 2 , the defective packaging box interception device 10 further includes a second positioning plate 16. The second positioning plate 16 is arranged between the fifth wheel 20 and the sixth wheel 30 and is arranged opposite to the first positioning plate 15. The first positioning plate 15 and the second positioning plate 16 can approach each other to clamp the packaging box pushed out by the fifth wheel 20. When the packaging box is pushed out by the fifth wheel 20, the first positioning plate 15 and the second positioning plate 16 approach each other to fold and clamp the packaging box again, improving the folding quality of the packaging box.

[0075] Among them, the folding plate 23 is located at the top of the first positioning plate 15 and the second positioning plate 16. The first positioning plate 15, the second positioning plate 16 and the folding plate 23 enclose a channel, and the channel is used to communicate with the first die box 22 and the second die box 32. During operation, when the packaging box is pushed out by the fifth wheel 20, the packaging box passes through the channel, and under the action of the first positioning plate 15, the second positioning plate 16 and the folding plate 23, the packaging box in the channel is folded and clamped again.

[0076] It should be noted that after the defective packaging box is ejected from the fifth wheel 20, the defective packaging box pushes the side of the blocking plate 13 away from the first positioning plate 15 to rotate in the direction away from the second positioning plate 16. The outlet formed between the blocking plate 13 and the sixth wheel 30 communicates with the channel, so that the defective packaging box in the channel can be discharged through the outlet, realizing the interception of the defective packaging box.

[0077] In one embodiment, referring to Figure 2 , the defective packaging box interception device 10 further includes a driving mechanism, a first connecting shaft 18 and a second connecting shaft 19. The first positioning plate 15 is arranged on the first connecting shaft 18 through a first support 181, and the second positioning plate 16 is arranged on the second connecting shaft 19 through a second support 191. The driving mechanism is connected to the first connecting shaft 18 and the second connecting shaft 19, and the driving mechanism is used to drive the first connecting shaft 18 to move along its axial direction and drive the second connecting shaft 19 to move along its axial direction, so that the first positioning plate 15 and the second positioning plate 16 approach or move away from each other. In this way, under the drive of the driving mechanism, the first positioning plate 15 and the second positioning plate 16 can automatically approach each other to automatically clamp the packaging box ejected from the fifth wheel 20.

[0078] In one embodiment, the packaging machine further includes a controller and an alarm. The controller is communicatively connected to the first detection mechanism 11 and the alarm. When the first detection mechanism 11 is triggered, the first detection mechanism 11 sends a signal to the controller, and the controller controls the alarm to start to remind the operator to process the defective packaging box in time.

[0079] In the defective packaging box interception device 10 of this embodiment, during operation, when the defective packaging box is ejected from the fifth wheel 20 into the channel. Due to the change in the size of the defective packaging box, the defective packaging box will squeeze the blocking plate 13, causing the spring ball to separate from the limit groove, and the blocking plate 13 rotates with the rotating seat 131, causing the detection rod to trigger the proximity switch. The proximity switch receives the signal and transmits it to the PLC, and the packaging machine stops and alarms. At the same time, during the rotation of the blocking plate 13, an outlet is formed between the blocking plate 13 and the sixth wheel 30, so that the defective packaging box in the channel can be discharged through the outlet. In this way, the interception of the defective packaging box on the fifth wheel 20 can be realized, and at the same time, the fifth wheel 20 and the sixth wheel 30 can be protected from damage.

[0080] This application also provides a method for intercepting defective packaging boxes, including the following steps:

[0081] S100. The defective packaging box is ejected from the fifth wheel 20.

[0082] S200. The defective packaging box squeezes the blocking plate 13, causing the blocking plate 13 to rotate to trigger detection. At the same time, an outlet is formed between the rotated blocking plate 13 and the sixth wheel 30, and the defective packaging box is discharged through the outlet.

[0083] In the above-mentioned defective packaging box interception method, when the defective packaging box is pushed out from the fifth wheel 20, due to the change in the shape and size of the defective packaging box, the defective packaging box will squeeze the interception plate 13, causing the interception plate 13 to rotate to trigger detection. At the same time, an outlet is formed between the rotated interception plate 13 and the sixth wheel 30, and the defective packaging box can be discharged through the outlet. If the packaging box is detected as a defective packaging box, the packaging machine stops, and the operator cleans the defective packaging boxes on the fifth wheel 20 and the sixth wheel 30. In this way, the defective packaging boxes on the fifth wheel 20 can be prevented from flowing into the next process, the interception time of the defective packaging boxes can be reduced, and the production quality of the packaging boxes can be improved.

[0084] In one embodiment, in step S200, referring to Figure 7 and Figure 8 , specifically includes the steps:

[0085] S210. After detecting the defective packaging box, the sensor outputs DC24V.

[0086] S220. The relay KA is energized, the normally closed contact is disconnected, and the self-diagnostic signal of the blockage sensors of the fifth wheel 20 and the sixth wheel 30 cannot be received by the input point of N12J20.

[0087] It should be noted that the same signal line is shared with the blockage detection of the fifth wheel 20 and the sixth wheel 30 of the original machine, and the self-diagnostic signal of the original machine detection is used to realize the detection and interception of the defective packaging boxes on the fifth wheel 20, reducing the electrical transformation cost.

[0088] S230. MICRO-II (the electric control system of the ZB45 unit) reports a fault of the self-diagnosis of the input point of N12J20.

[0089] In this way, by using mechanical triggering and electrical detection, double protection can be achieved to protect the fifth wheel 20 and the sixth wheel 30, reduce the number of damages to the fifth wheel 20 and the sixth wheel 30, shorten the maintenance time, and improve the operating efficiency of the packaging machine.

[0090] In one embodiment, after step S200, it further includes the steps:

[0091] S300. The packaging machine stops.

[0092] Specifically, after the packaging machine stops, the fault information "Sensor diagnosis fault: N12202S515" is displayed on the OPC display screen.

[0093] S400. Clean the defective packaging boxes on the fifth wheel 20 and / or the sixth wheel 30.

[0094] Specifically, when the operator finds this fault on the OPC display screen, the operator immediately processes the defective packaging boxes on the fifth wheel 20 and / or the sixth wheel 30.

[0095] S500 and the manual reset intercepting plate 13.

[0096] Specifically, after the intercepting plate 13 is reset, the first limiting structure 1311 and the second limiting structure 1511 are in limiting cooperation to restrict the rotation of the intercepting plate 13.

[0097] S600. After resetting the fault information, restart the machine, and the packaging machine operates normally.

[0098] Among them, for the self-diagnosis of the MICRO-II system: the input points of the input board receive the pulse signals sent by the sensors. Once an input point does not receive this pulse signal, the system reports a self-diagnosis fault at this point.

[0099] N12J20: The 12th control board of MICRO-II (the electrical control system of the packaging machine), with 20 pins, referring to the signal access position.

[0100] OPC display screen: The operation control screen built in the packaging machine, which can view fault information and parameter editing.
