The limit fit mode of the blocking groove 231 and the grid 25 can be a contact blocking or contact clamping mode, namely after the grid 25 moves to the blocking groove 231, the blocking groove 231 blocks the grid 25 through the contact blocking or contact clamping mode, so that the grid 25 drives the pushing disc 23 to rotate, and meanwhile the pushing disc 23 pushes the grid 25 to move left and right.

When the automatic side pushing device is used, the packing box 80 is driven by the power of the previous procedure or the power of the conveyor 10 to move forwards on the conveyor 10, after the packing box 80 contacts one packing box fixing unit, the packing box fixing unit is driven to move forwards continuously and is fixed by the baffle plate 25 and the two side limiting assemblies in a limiting manner, meanwhile, the packing box fixing unit rotates around the axis of the rotating shaft 22, at the moment, the packing box 80 is just fixed in the packing box fixing unit, then the packing box fixing unit continues to move forwards, the baffle plate 25 moves forwards to the position of the front pushing plate 23 under the driving of the packing box 80, one side edge of the baffle plate 25 enters the blocking groove 231 of the front pushing plate 23 and drives the pushing plate 23 to rotate, and the baffle plate 25 can move left and right under the limiting of the side moving connecting rod 24, so that the pushing plate 23 is pushed to move axially along the rotating shaft 22 while rotating; the barrier 25 then continues to move forward to the rear pushing tray 23, and likewise, the other side edge of the barrier 25 enters the blocking groove 231 of the rear pushing tray 23, and drives the pushing tray 23 to rotate and simultaneously push the barrier 25 to move along the axial direction of the rotating shaft 22, so that the barrier 25 is reset to be in contact with the next package 80, and meanwhile, the package 80 is driven by the two pushing trays 23 to shake left and right, and then the package 80 continues to move forward to be separated from the package fixing unit and is detected through the gate-type frame 30, and the rear package fixing unit just moves to the starting position of the package fixing unit again, so that the process can be completed in cooperation with the next package 80. The right and left sides herein refer to the right and left sides with reference to the running direction of the packing box 80.

The packing box 80 to be detected is transported to the conveyor 10 through the previous process, is rocked through the rocking mechanism, is detected by the filler detecting assembly 50 through the gate frame 30, is directly passed through if being correctly filled, and can perform preset operations including alarming or stopping if not being correctly filled.

Compared with the prior art, when the packing box filler detection device provided by the embodiment is used, the packing box 80 to be detected is transported to the conveyor 10 through the previous procedure, is rocked left and right through a rocking mechanism formed by the support frame 21, the rotating shaft 22, a plurality of packing box fixing units, the two pushing discs 23 and other parts, is detected to be correctly filled through the filler detection assembly 50 by the door-shaped frame 30, and if the packing box is correctly filled, the packing box 80 directly passes through the packing box, and if the packing box is not correctly filled, preset operations such as alarming, stopping and the like can be performed; since the bottle placement positions of the device for filling the bottles into the packing box 80 are fixed, the packing box 80 and the bottles therein can be rocked by the rocking mechanism, if the bottles in the packing box 80 are not fixed by the filling material, the bottles can displace or topple in the packing box 80, and can be detected more easily when passing through the filling material detection assembly 50; therefore, the method not only can detect whether the filling material in the packaging box is correctly filled after the packaging box is sealed, but also can replace manual detection, improve the detection precision and reduce the labor cost, and can repeatedly detect and confirm the packaging box 80 after the packaging box is sealed before storage and transportation, thereby ensuring the accurate degree of detection and avoiding missing detection; simultaneously through the cooperation of two top pushing plates 23, side shift connecting rod 24 and spacer 25 for when rocking, only need rock the packing box fixed unit with packing box 80 contact, can reduce rocking mechanism's self load, and pivot 22 itself only need rotate with support frame 21 be connected can, connected form is simple, and is not fragile, is favorable to guaranteeing structural safety.

The packing box filler detection device further comprises a controller 51 and an alarm assembly 52, wherein the controller 51 is respectively and electrically connected with the filler detection assembly 50 and the alarm assembly 52 so as to control the alarm assembly 52 to send out an alarm signal according to a signal transmitted by the filler detection assembly 50. In this way, after the filler detecting component 50 detects that the filler material in the packaging box 80 is not properly filled, a signal is transmitted to the controller 51, and the controller 51 controls the alarm component 52 to send out an alarm signal so as to remind a user of the alarm.

Further, the controller 51 is electrically connected to the electronic control part of the conveyor 10, so as to control the conveyor 10 to stop running after the filler detecting assembly 50 detects that the filler in the packaging box 80 is not properly filled, thereby avoiding that the user does not receive the alarm signal in time or does not process the alarm signal in time, so that the packaging box 80 with problems is difficult to find.

Specifically, the conveyor 10 includes a carrier roller conveyor or a belt conveyor or other conveying device capable of driving the packing box 80 through the shake mechanism and the filler detection assembly 50; the filler detection assembly 50 comprises one or more of ultrasonic probes, X-ray probes or electromagnetic detection probes and the like capable of detecting the filler in the packaging box 80, wherein the ultrasonic probes can judge whether the filler is filled correctly through density and shape differences, the ultrasonic probes are suitable for beverages with thinner packaging boxes, the X-ray probes can judge whether the filler is filled correctly through shape differences, the ultrasonic probes are suitable for beverages without metal packaging, the electromagnetic detection probes can judge whether the filler is filled correctly through metal material differences, and the ultrasonic detection probes are particularly suitable for aluminum cans or iron tube beverages; the alarm assembly 52 includes one or more of an indicator light, a speaker, a vibrator, a display, or a wireless communication module, etc. that is capable of providing an alarm signal to a user; the controller 51 includes one or more of components such as a PLC controller or an industrial personal computer capable of receiving, processing and judging the detection signal from the filler detection component 50 and controlling the alarm component 52 according to the detection signal.

For more accurate detection, an identification strip can be attached to a filling material such as foam, the filling material detection component 50 can be detection equipment such as an ultrasonic probe, an X-ray probe, an electromagnetic detection probe or a bluetooth module, and the like, which can be matched with the identification strip for identification, and the identification strip can be an adhesive with ultrasonic characteristics, X-ray characteristics, electromagnetic characteristics or bluetooth characteristics, and is attached to one side of the filling material facing the electromagnetic detection probe.
