Description

Technical Field

[0001] The invention relates to the technical field of case packing machines, in particular to a bottle conveying mechanism in a case packing machine. Background Art

[0002] The case packing machine mainly includes: a robot and a bottle conveying mechanism and a box conveying mechanism arranged in parallel. The bottle conveying mechanism is used to convey the bottles to be boxed, and the box conveying mechanism is used to convey the boxes. The robot is used to grab the bottles in the bottle conveying mechanism and place them in the boxes in the box conveying mechanism. The bottle conveying mechanism includes: a conveyor belt, on which a number of bottle separation plates are arranged, and a conveying channel is formed between adjacent bottle separation plates. The two ends of the conveying channel are respectively a bottle feeding end and a bottle blocking end. The bottle blocking end of each conveying channel is fixedly provided with a bottle blocking device. Bottles enter each conveying channel from the bottle feeding end, and the bottles are closely arranged in sequence under the blocking of the bottle blocking device in each conveying channel.

[0003] The above-mentioned packing machine has the following defects: 1. After the robot completes the action of grabbing and placing bottles, it needs to wait for the next group of bottles to be delivered to the place, and the bottle conveying mechanism stops before it can grab the next bottle, which greatly affects the packing efficiency. 2. The bottles in each conveying channel are arranged in sequence under the blockage of the bottle blocking device, which causes the bottles to be squeezed and deformed greatly, making it difficult for the robot to grab accurately, thereby reducing the packing efficiency.

[0004] With the continuous improvement of the production capacity of liquid packaging production lines, packaging production efficiency needs to be further improved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a dynamic bottle blocking device in a bottle conveying mechanism of a case packing machine, which can greatly reduce the squeezing force between bottles and greatly improve the case packing efficiency.

[0006] To solve the above problems, the technical solution adopted by the present invention is: a dynamic bottle blocking device in a bottle conveying mechanism in a cartoning machine, comprising: a bottle blocking bracket arranged on a frame, a plurality of bottle blocking assemblies arranged on the bottle blocking bracket, each bottle blocking assembly corresponding to a conveying channel, the bottle blocking bracket is slidably connected to the frame, a driving mechanism is arranged on the frame, and the bottle blocking bracket can slide back and forth on the frame under the drive of the driving mechanism, thereby driving each bottle blocking assembly to move back and forth in the corresponding conveying channel, a first position sensor, a second position sensor, and a third position sensor are arranged at intervals on the bottle blocking bracket, and the bottle closest to the bottle blocking assembly in the conveying channel can be detected by the first position sensor, the second position sensor, and the third position sensor in sequence during the process of moving toward the bottle blocking assembly until it is blocked in place.

[0007] Furthermore, in the aforementioned dynamic bottle blocking device in the bottle conveying mechanism of the case packing machine, the first position sensor, the second position sensor and the third position sensor are all photoelectric sensors.

Until the sensing baffle rotates to the blocking position, the sensing baffle at the blocking position can block the light beam emitted by the transmitter in the third position sensor, and the connecting end of the driving plate drives the baffle to rotate upward around the mounting axis until the lower end of the baffle breaks away from the stopper and is lifted upward; the bottle that runs to the baffle can overcome the gravity of the counterweight block and press the baffle downward, so that the connecting end of the baffle and the driving plate rotates downward around the mounting axis, thereby causing the counterweight end of the driving plate to rotate upward around the mounting axis; when the lower end of the baffle is in contact with the stopper, that is, the bottle is in place, the sensing baffle rotates away from the blocking position, and the light beam emitted by the transmitter in the third position sensor can be received by the receiver, which enables the third position sensor to detect that a bottle closest to the bottle assembly in each conveying channel is in place.

[0009] Furthermore, in the aforementioned dynamic bottle blocking device in the bottle conveying mechanism of the cartoning machine, the sliding connection structure between the bottle blocking bracket and the frame includes: slide rails are respectively provided on both sides of the frame, and a slider is provided on the slide rails on each side, and the two ends of the bottle blocking bracket are respectively fixed to the slider.

[0010] Furthermore, the dynamic bottle blocking device in the bottle conveying mechanism of the aforementioned cartoning machine, wherein the structure of the driving mechanism includes: synchronous belts are respectively arranged on both sides of the bottle conveying mechanism, the synchronous belts on each side are arranged on a synchronous pulley, the synchronous pulleys on both sides are respectively installed on the driving shaft and the driven shaft on the frame, the driving shaft is driven by a servo motor, and the servo motor is installed on the frame.

[0011] The advantages of the present invention are as follows: 1. The bottle blocking bracket for installing the bottle blocking assembly can slide on the slide rail under the drive of the servo motor, and the servo motor can drive the bottle blocking bracket to run at the same speed as the bottle, thereby realizing dynamic bottle blocking. The advantage of dynamic bottle blocking is that it greatly reduces the squeezing effect between bottles, thereby greatly reducing the squeezing deformation between bottles, and thus greatly improving the accuracy of the robot grabbing bottles. 2. Since the first position sensor, the second position sensor, and the third position sensor are arranged on the bottle blocking bracket, each sensor feeds back the detected signal to the PLC controller, and the servo motor also feeds back the speed signal to the PLC controller, the PLC controller can control the running speed of the robot according to the information obtained, so that the robot and the bottle can be dynamically grabbed after the running speed is consistent, so that the bottle conveying mechanism always maintains the bottle feeding state without stopping, and the efficiency of grabbing bottles and packing is greatly improved.
