[0002] Compared with traditional pharmaceutical packaging materials such as glass, plastic bottles have the advantages of good chemical stability, high barrier properties, light weight, and being not easily broken, and are widely used. When loading plastic bottles onto a tray, in order to prevent the plastic bottles from tipping over or squeezing against each other in the tray, multiple rows of partitions are usually provided in the tray for blocking.

[0003] Such as Figure 1 , in the existing plastic bottle tray loading device, the positions between the clamps A1 are fixed, and there is a certain distance L1 between the clamps A1. When placing plastic bottles into the tray A2, there are usually multiple rows of gaps between the plastic bottles in the tray A2. After the gaps are filled with plastic bottles by the clamps A1, it is necessary to move a long distance L4 to place more materials, which affects the placement efficiency of the plastic bottles. Even if the distance L1 between the clamps A1 is reduced, it is still necessary to provide a moving space L3 when the clamps A1 are opened, resulting in a relatively large distance L2 between the partitions in the tray, and it is difficult to place more plastic bottles in the limited tray A2.

Detailed Description of the Invention

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0019] Refer to Figures 2 to 10 , and the present application will be further described in detail: Combined with Figure 2 , a fully automatic plastic bottle tray loading device includes a frame 00, a tray feeding device 4 for supplying tray A2, and at least one transfer unit 1 provided on the frame 00; in this embodiment, there are two transfer units 1, which can load the tray A2 synchronously or alternately to improve the tray loading efficiency.

[0020] Each transfer unit 1 includes a tray loading device 2 and a feeding device 3 provided at the bottom of the tray loading device 2. The feeding device 3 is used to shape the plastic bottles A3 and place them in at least two rows to provide materials for the tray loading device 2; among them, the tray feeding device 4, the feeding device 3, and the tray loading device 2 are arranged in a layered structure from bottom to top, which can greatly reduce the floor area.

[0021] The tray loading device 2 includes a driving mechanism 21 and a picking mechanism 22. The driving mechanism 21 can drive the picking mechanism 22 to reciprocate between the feeding device 3 and the tray feeding device 4 to transfer the plastic bottles A3.

[0022] When picking up, the picking mechanism 22 can adjust the picking width to be consistent with the spacing of at least two rows of plastic bottles A3 on the feeding device 3 and pick up the plastic bottles A3; when placing, the picking mechanism 22 can shorten the width between the at least two rows of plastic bottles A3 picked up, that is, reduce the distance L1 between the two rows of plastic bottles A3.

[0023] The picking mechanism 22 includes at least two clamping components (22A and 22B) arranged in parallel, and a distance adjusting mechanism 24 for driving the clamping components (22A and 22B) to approach or move away from each other. Each clamping component (22A or 22B) can pick up a single row of plastic bottles A3.

[0024] In this embodiment, the picking mechanism 22 includes at least one first clamping component 22A fixedly connected to the driving mechanism 21 and at least one second clamping component 22B slidably connected to the driving mechanism 21; wherein, both the first clamping component 22A and the second clamping component 22B are one; when both the first clamping component 22A and the second clamping component 22B pick up a whole row of plastic bottles A3, the distance adjusting mechanism 24 can drive the second clamping component 22B to approach the first clamping component 22A, reducing the distance therebetween. The distance adjusting mechanism 24 can be a cylinder, and the cylinder is arranged on the second clamping component 22B, and its driving end is connected to the first clamping component 22B. Of course, it can also be other linear driving mechanisms, such as a lead screw mechanism, etc.

[0025] In an embodiment not shown, the clamping components can also be movably arranged on the driving mechanism 21, and the distance adjusting mechanism 24 drives the clamping components to approach or move away from each other.

[0026] In some embodiments, there can be three clamping components. The first clamping component 22A can be in the middle, and the second clamping components 22B are respectively arranged on both sides of the first clamping component 22A; during operation, the distance adjusting mechanism 24 drives the second clamping components 22B on both sides to move closer to the middle; of course, either one of the two sides can be the first clamping component 22A, and the remaining two are the second clamping components 22B arranged on the same side of the first clamping component 22A, and are respectively driven by independent distance adjusting mechanisms 24; during operation, the two second clamping components 22B move towards the side where the first clamping component 22A is arranged to adjust the distance between them.

[0027] Compared with the prior art, on the premise of the same-sized tray A2 and the same-specification plastic bottles A3, the present application can adjust the distance between the first clamping component 22A and the second clamping component 22B to reduce the distance L1 between the picked-up whole rows of plastic bottles, and further can reduce the distance L2 between the partitions in the tray A2. Therefore, more plastic bottles A3 can be placed in the limited tray A2, improving the loading efficiency; such as Figure 10 At the same time, it can avoid too large a distance between the whole rows of plastic bottles placed in the tray A2, reduce the moving distance L4 of the picking mechanism, and improve the loading efficiency.

[0028] Combined with Figure 5, wherein, the first clamping component 22A and the second clamping component 22B have the same structure and both include a carrier plate 220 connected to the driving mechanism 21, and at least one jaw component 221 provided on the carrier plate 220 for picking up the plastic bottle A3. The jaw component 221 includes a pair of openable and closable clamping plates 2210, and the clamping plates 2210 can be driven by a cylinder to open and close. In this embodiment, a clamping block is provided at the end of the cylinder, and opposite slots are provided on the clamping plates 2210, and the clamping block is clamped in the slots.

[0029] The driving mechanism 21 can drive the picking mechanism 22 to reciprocate between the feeding device 3 and the tray device 4 to transfer the plastic bottle A3. Among them, the driving mechanism 21 includes a first linear driving component 211 and a second linear driving component 212. The first linear driving component 211 is used to drive the picking mechanism 22 away from or close to the tray A2 or the feeding device 3, and the second linear driving component 212 drives the picking mechanism 22 to move between the tray A2 and the feeding device 3.

[0030] Both the first linear driving component 211 and the second linear driving component 212 include a driving part and a reciprocating moving part. The driving part is used to drive the reciprocating part to drive the picking mechanism 22 to move. In this embodiment, the driving part is a motor, and the reciprocating moving part can be a gear-rack mechanism or a lead screw mechanism, etc. Of course, in an embodiment not shown, the driving mechanism 21 can be a robotic arm.

[0031] Combined with Figure 4 , in one embodiment, in order to prevent the picked plastic bottle A3 from tilting, a sorting component 23 for restricting the position of the picked plastic bottle A3 is further included. The sorting component 23 is attached to the clamping component. Among them, the sorting component 23 can be provided at the bottom of the clamping component. When picking up the plastic bottle A3, the plastic bottle A3 passes through the sorting component 23 and is clamped by the jaw component 221.

[0032] The sorting component 23 includes a limiting frame that can move in the z-axis direction ( Figure 4 which is the up and down direction in the figure). Among them, the limiting frame can be connected to the jaw component 221 through a cylinder, and the limiting frame is driven by the cylinder to move in the z-axis direction to sort the state of the plastic bottle A3. The limiting frame is in a frame structure, and the limiting frame is connected to the bottom of the jaw component 221 to ensure that the state of the picked row of plastic bottles A3 is consistent, prevent the plastic bottle A3 from tilting, so as to facilitate subsequent smooth placement between two adjacent partitions in the tray A2.

[0033] Combined with Figure 6, the feeding device 3 includes at least two parallel conveyor chain plates 31 for conveying plastic bottles A3 to supply materials to the tray loading device 2. In this embodiment, there are two conveyor chain plates 31, which are matched with the picking mechanism 22, and the conveyor chain plates 31 are driven synchronously. Of course, more than two conveyor chain plates 31 can also be provided according to requirements, and the conveyor chain plates 31 can be driven separately to convey plastic bottles.

[0034] Since the temperature of the body of plastic bottle A3 is high after filling, the plastic bottles A3 are crowded with each other during transportation, which may cause the plastic bottles A3 to deform or stick together, and the body of the bottle rotates, resulting in the bottle mouth not being on the same straight line.

[0035] To prevent the plastic bottles A3 from being crowded during transportation, resulting in the rotation of the body of plastic bottle A3, the bottle mouths of plastic bottles A3 not being on the same straight line, the adhesion between plastic bottles A3, or the phenomenon of the plastic bottle having a crooked neck; combined with Figure 6 , it further includes a shaping mechanism 32 provided at the feeding end of the feeding device 3 ( Figure 6 the left end in Figure 8 ) which can squeeze and adjust the state of the plastic bottles to ensure that the states of the plastic bottles are consistent, that is, adjust the plastic bottles A3 whose bodies rotate during transportation, so that the bottle mouths of the whole row of plastic bottles A3 on the conveyor chain plate 31 are on the same straight line, so that the subsequent picking mechanism 22 can pick up the whole row of plastic bottles A3 without missing any. Combined with

[0036] Combined with Figure 6 , it further includes a separating mechanism 33 and a bottle blocking mechanism. The separating mechanism 33 and the bottle blocking mechanism are respectively arranged on both sides of the conveyor chain plate 31 in a relatively arranged manner, and the separating mechanism 33 and the bottle blocking mechanism 34 are connected to the rear end of the shaping mechanism 32. The separating mechanism 33 is used to separate the plastic bottles A3 to prevent the plastic bottles A3 from being crowded together. The bottle blocking mechanism 34 includes a baffle for cooperating with the separating mechanism 33 to block the plastic bottles A3 to prevent the plastic bottles A3 from shaking and falling out of the conveyor chain plate 31 during transportation.

[0037] Combined with Figure 7 , wherein, the separating mechanism 33 includes a rotatable synchronous belt 331, and a number of baffles 330 are evenly distributed on the synchronous belt 331. Among them, the synchronous belt 331 is supported by belt pulleys 332, and the belt pulleys 332 are driven by a motor to drive the synchronous belt 331 to rotate.

[0038] Combined with Figure 6, the shaping mechanism 32 includes a first conveying component 321 and a second conveying component 322 which are oppositely arranged on both sides of the conveying chain plate 31. The first conveying component 321 and the second conveying component 322 convey and squeeze the body of the plastic bottle A3 entering between them. By squeezing the bottle body, the mouth of the crooked-neck plastic bottle A3 is straightened, and at the same time, the rotating plastic bottle A3 is straightened, ensuring that the bottle body and the bottle mouth are on the same straight line, and conveying the plastic bottle A3 to the side of the separating mechanism 33.

[0039] When the number of plastic bottles on the separating mechanism 33 reaches the upper limit, the shaping mechanism 32 stops working, can block the plastic bottles on the conveying chain plate 31, and stops conveying plastic bottles to the separating mechanism 33.

[0040] Combined with Figure 6 , the feeding ends ( Figure 6 the left end in ) of the first conveying component 321 and the second conveying component 322 both expand outwards. That is, the feeding ends of the first conveying component 321 and the second conveying component 322 are in a "V" shape towards the feeding end side of the conveying chain plate 31, which can guide the plastic bottle A3 to smoothly enter the shaping mechanism 32, prevent the rotated plastic bottle A3 from getting stuck at the feeding end of the shaping mechanism 32, and adjust the body of the plastic bottle A3 during the conveying process.

[0041] Combined with Figure 7 and Figure 8 , the first conveying component 321 and the second conveying component 322 both include a power component and a number of support rollers 3212. A shaping conveyor belt 3211 is sleeved outside the support rollers 3212. The power component is used to drive any one of the support rollers 3212 to drive the shaping conveyor belt 3211 to rotate. A guide plate 324 is arranged between adjacent support rollers 3212, and the guide plate 324 is used to support the inner side of the shaping conveyor belt 3211; the power component is a motor.

[0042] Combined with Figure 8 , in this embodiment, a transition component is connected between the first conveying component 321 and the separating mechanism 33. The transition component is used to limit the state of the plastic bottle A3 after being shaped and separated by a certain distance X between the first conveying component 321 and the second conveying component 322, and stably convey it to the separating mechanism 33, preventing the plastic bottle from rotating after leaving the shaping mechanism 32 and the state of the plastic bottle from changing, so that the baffle 330 can be inserted into the gap X to pick up the plastic bottle, and at the same time, preventing the plastic bottles A3 from sticking together.

[0043] The transition component includes a transition belt 323 that can rotate following the first conveying component 321. In this embodiment, the transition belt 323 is sleeved outside the support roller 3212 and the belt pulley 332, and the transition belt 323 rotates synchronously with the shaping conveyor belt 3211. The transition component is arranged at the bottom of the first conveying component 321. Of course, the transition component can also be arranged at the top of the first conveying component 321, or it can rotate following the synchronous belt 331 or be driven by an independent motor.

[0044] During operation, the plastic bottle A3 passes through the feeding end ( Figure 6 the left end in this case) of the conveying chain plate 31 and is successively shaped and separated by the shaping mechanism 32. Then, the transition component conveys the adjusted plastic bottle A3 to the separating mechanism 33 one by one. After receiving the sorted plastic bottle A3, the separating mechanism 33 arranges the plastic bottle A3 at intervals one by one to prevent the plastic bottle A3 from being crowded together and causing the bottle body to deform.

[0045] Combined with Figure 9 , the tray feeding device 4 includes a tray conveying mechanism 41, a fixing component 43 arranged on the tray conveying mechanism 41 for clamping and fixing the tray A2, and a limiting component 42 for restricting the position of the tray A2. The tray conveying mechanism 41 is used to convey the tray A2. When the limiting component 42 restricts the position of the tray A2, the fixing component 43 clamps and fixes the tray A2.

[0046] Among them, the tray conveying mechanism 41 can be a roller conveying mechanism, a belt conveying mechanism, or a chain conveying mechanism. In this embodiment, the tray conveying mechanism 41 is a chain conveying mechanism, and there is no limitation here.

[0047] The limiting component 42 can be a telescopic cylinder or a sensor, etc. In this embodiment, the limiting component 42 is a telescopic cylinder. During operation, the telescopic cylinder extends the driving end to block the tray A2 on the tray conveying mechanism 41 to determine the position of the tray A2. When the limiting component 42 is a sensor, the position of the tray A2 is detected and determined. When the sensor detects that the tray A2 has moved in place, the tray conveying mechanism 41 stops conveying the tray A2. There is no limitation here.

[0048] The fixing component 43 is used to clamp the tray A2. In this embodiment, the fixing component 43 is a cylinder, and a clamping block is arranged at the driving end of the cylinder. When fixing, the cylinder drives the clamping block to extend and clamp the tray A2. Of course, it can also be clamped by rotation, such as a rotary cylinder. There is no limitation here.
