Description

Technical Field

[0001] The present invention relates to the technical field of cartoning equipment, and more particularly, to a bottle separating device for preventing bottle tipping and an automatic cartoning machine. Background Art

[0002] In a liquid preparation workshop, an automatic cartoning machine can be used for the canning, conveying, and packaging of medicine bottles. However, since the products are filled in large medicine bottles, this results in a large frictional force between the bottom of the medicine bottle and the conveyor belt during transportation. With the increase in frictional force, the thrust generated also increases, which causes the medicine bottles to be squeezed at the bottle separating screw. At the same time, since the speed of the automatic cartoning machine inside the bottle separating screw is different from that before entering the bottle separating screw, and there is a certain probability that the medicine bottle will hit the thread at the end of the bottle separating screw when it reaches the inlet of the bottle separating screw, resulting in the medicine bottle tipping away from the bottle separating screw, that is, the bottle is prone to tipping at the inlet of the bottle separating screw. Bottle tipping easily causes the bottle to break, and in severe cases, it may lead to the chain breaking, component damage and deformation, and the entire equipment being paralyzed and unable to operate normally.

[0030] Embodiment

[0031] Combined with Figures 1 to 3As shown in the figure, this embodiment provides an automatic cartoning machine, which includes a frame 10 and a bottle separating device for preventing bottles from falling down. The bottle separating device for preventing bottles from falling down is arranged on the frame 10. The bottle separating device for preventing bottles from falling down includes a track 11 for the movement of medicine bottles, and also includes: a separating screw 20, a bottle blocking device 30, a first sensor 40, a second sensor 50, a sensor 60 and a controller. Among them, the controller is electrically connected to the bottle blocking device 30, the first sensor 40, the second sensor 50 and the sensor 60. The separating screw 20 is arranged in parallel with the track 11 and has a thread groove suitable for accommodating medicine bottles. The first sensor 40 is arranged at the medicine bottle inlet 70 of the separating screw 20. The second sensor 50 is arranged on the track 11 and is located on the side of the first sensor 40 away from the separating screw 20. The sensor 60 is arranged on the separating screw 20. The bottle blocking device 30 is arranged at the medicine bottle inlet 70 of the separating screw 20.

[0032] The controller is configured to:

[0033] Receive the first signal sent by the first sensor 40 and judge whether there is a medicine bottle at the first position where the first sensor 40 is located according to the first signal.

[0034] When it is judged that there is a medicine bottle at the first position, send an opening instruction to the second sensor 50 to enable the second sensor 50 to start detection.

[0035] Receive the second signal sent by the second sensor 50 and judge whether there is a medicine bottle at the second position where the second sensor 50 is located according to the second signal.

[0036] Receive the third signal sent by the sensor 60 and judge the current thread position of the separating screw 20 according to the third signal.

[0037] When it is judged according to the second signal that there is a medicine bottle at the second position and the current thread position of the separating screw 20 is suitable for the first medicine bottle to enter the thread groove, control the bottle blocking device 30 to cancel the blocking of the medicine bottle at the first position, so that the medicine bottle at the first position enters the separating screw 20. In this embodiment, the track 11 is arranged on the frame 10, and a conveyor belt is arranged on the track 11 for driving the medicine bottles to move continuously. A railing 12 is arranged on the side of the track 11 for limiting the medicine bottles to prevent the medicine bottles from leaving the track 11. Here, before the medicine bottle enters the separating screw 20, it is conveyed by the conveyor belt. After the medicine bottle enters the area of the separating screw 20, it moves under the drive of the separating screw 20.

[0038] Continue to combine Figures 1 to 3As shown, the bottle-dividing screw 20 rotates self-driven by a chain drive. It is arranged on the side of the track 11 and is parallel to the track 11. The bottle-dividing screw 20 includes a cylindrical end 21 and a threaded end 22. The cylindrical end 21 is the medicine bottle inlet 70. The threaded end 22 continuously rotates to separate the medicine bottles entering its thread grooves by the threads. Only one medicine bottle is accommodated in each thread groove, and the medicine bottles move along the track driven by the bottle-dividing screw 20.

[0039] In this embodiment, the first sensor 40 and the second sensor 50 are optoelectronic switches. The first sensor 40 is arranged at the medicine bottle inlet 70, and the second sensor 50 is arranged on one side of the first sensor 40 away from the threaded end 22 of the bottle-dividing screw 20. Here, both the first sensor 40 and the second sensor 50 are electrically connected to the inductor 60 and the bottle-blocking device 30. The controller can be a control system, such as a circuit board or an external control program, etc.

[0040] The inductor 60 includes a magnetic proximity switch. The magnetic proximity switch is arranged at the front end of the screw of the bottle-dividing screw 20, that is, on the cylindrical end 21 and close to the outer surface of the cylinder. It is adapted to match with the magnet block correspondingly arranged at the medicine bottle inlet 70 of the track 11. Of course, here it can also be directly made to match with the electromagnet 32 on the bottle-blocking device 30. Here, the magnetic proximity switch can rotate with the cylindrical end 21. When it rotates one circle, it just senses the magnet block and generates an electrical signal to be transmitted to the bottle-blocking device 30. Of course, the magnetic proximity switch can also be arranged on the track 11 at the medicine bottle inlet 70, and the magnetic block is arranged on the cylindrical end. When the cylindrical end 21 rotates to make the magnetic block close to the magnetic proximity switch, the magnetic proximity switch generates an electrical signal. In other embodiments, the inductor 60 can also use induction devices such as Hall elements, which can also achieve this effect. Here, for the setting of the magnetic proximity switch, it corresponds to the starting point of the thread of the threaded end 22, so that when the magnetic proximity switch senses the magnet block, the starting point of the thread of the threaded end 22 just approaches the medicine bottle at the medicine bottle inlet 70, enabling the medicine bottle to smoothly enter the thread groove of the bottle-dividing screw 20. That is, when the bottle-dividing screw rotates to a position where its thread is just suitable for the medicine bottle to enter its thread groove, it just enables the magnetic proximity switch to sense the magnetic block, and then generates an electrical signal.

[0041] The bottle blocking device 30 is arranged at the same position on the track 11 as the connection between the cylindrical end 21 and the threaded end 22, and includes a condensation device and a baffle 31. The baffle 31 is made of metal, and the blocking end is arranged at the intersection of the cylindrical end 21 and the threaded end 22 of the bottle separation screw 20. The condensation device is electrically connected to the sensor 60 and the second sensor 50, and is configured to drive the baffle 31 to move downward after receiving the electrical signals from the sensor 60 and the second sensor 50 at the same time, thereby canceling the blocking of the track 11. Here, the condensation device includes an electromagnet 32, a spring and a movable rod, the upper end of the movable rod is connected to the baffle 31, and the spring is arranged on the movable rod and is located between the baffle 31 and the electromagnet 32. When the electromagnet 32 ​​receives the electrical signals from the first sensor 40, the second sensor 50 and the sensor 60 at the same time, it generates suction force on the baffle 31, so that the baffle 31 moves downward with the movable rod, removes the obstruction to the medicine bottle, and allows the medicine bottle to enter the bottle-separating screw 20. At this time, the thread starting point of the bottle-separating screw 20 is exactly located at the bottle inlet 70, so that the medicine can smoothly enter the bottle-separating screw 20. When the medicine bottle is released, the electromagnet 32 ​​cancels the suction effect on the baffle 31, and blocks the bottle inlet 70 again under the rebound effect of the spring. Of course, the bottle blocking device 30 here can also use other structures, such as setting a telescopic cylinder to control the baffle 31 through the cylinder, or setting a linear motor to control the up and down movement of the baffle 31, all of which are within the protection scope of the present invention.

[0042] In this embodiment, the working principle is as follows: when the first sensor 40 detects a medicine bottle, an electrical signal is given to the second sensor 50 to start; when the second sensor 50 detects the second medicine bottle, and the magnetic proximity switch installed at the front end of the bottle separation screw 20 detects the magnet installed at the bottle inlet 70 of the bottle separation screw 20, the electromagnet 32 ​​of the bottle blocking device is controlled to work by suction, and a medicine bottle is allowed to pass. That is, the first sensor 40, the second sensor 50 and the magnetic proximity switch are triggered at the same time to trigger the bottle blocking device 30 to work so as to achieve the function of bottle separation and bottle sorting. In this design, since the first medicine bottle can only be released when the second sensor 50 detects the second medicine bottle, in this way, when the first medicine bottle enters the working position of the bottle separation screw 20, if it is hit by the thread of the bottle separation screw, it can be blocked by the second medicine bottle behind, thereby preventing the first medicine bottle from tipping over, thereby achieving the effect of preventing the bottle from tipping over.

[0043] In another preferred embodiment, the controller is further configured to control the bottle blocking device 30 to cancel the blocking of the medicine bottle at the first position when no medicine bottle is detected at the second position for more than a preset time and the current thread position of the bottle-collecting screw 20 is suitable for the first medicine bottle to enter the thread groove, so that the medicine bottle at the first position enters the first thread groove of the bottle-collecting screw 20.

[0044] By setting the NAND gate logic principle of the photoelectric sensor, two sensors and an inductor 60 are set to control the bottle blocking device 30, so that when the medicine bottle moves to the inlet of the bottle separating screw 20, it can smoothly enter the thread groove, preventing the medicine bottles from stacking at the inlet 70 of the bottle and causing the medicine bottles to fall. Through the present invention, the labor cost can be effectively saved, the stability of the cartoning machine is improved, the occurrence of equipment shutdown caused by the falling of the bottles is reduced, and the production quality and production efficiency are improved. At the same time, the service life of the cartoning machine is increased, the fault problems such as chain misalignment caused by the bottle separating screw 20 squeezing the medicine bottles due to the falling of the bottles are reduced, thereby increasing the service life of the bottle separating screw 20 and reducing the maintenance cost.

[0045] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
