Description

Technical Field

[0001] This application relates to the technical field of palletizing machines, and particularly to a plastic bottle feeding device. Background Art

[0002] After the plastic bottles are filled, the temperature of the bottle body is relatively high. During the subsequent conveying process, due to the mutual congestion of the plastic bottles during the conveying process, the plastic bottles will be deformed or adhered together. The plastic bottles are congested on the conveying line, so the bottle body will rotate and other reasons, resulting in the bottle mouths of the whole row of plastic bottles not being on the same straight line. On the one hand, the congestion of the plastic bottles is likely to cause the bottle body to be deformed easily, affecting the product quality. On the other hand, when picking up the whole row of plastic bottles subsequently, due to the bottle mouths not being on the same straight line, it is easy to miss grasping. Therefore, after being placed in the tray, due to the gaps between the plastic bottles, the plastic bottles on both sides are likely to fall over, and usually manual intervention is required, making it difficult to achieve automatic feeding. Summary of the Invention

[0003] In view of the above problems, this application provides a plastic bottle feeding device, which can ensure that the states of the plastic bottle body and the bottle mouth are consistent, facilitate subsequent picking, ensure product quality, and meet the requirements of automatic feeding. The following technical solutions are adopted: The plastic bottle feeding device includes at least one conveying chain plate for conveying plastic bottles along the conveying direction, and a bottle separating and sorting device arranged on the conveying chain plate. The bottle separating and sorting device includes a shaping unit and a bottle separating unit arranged on the conveying chain plate in sequence along the conveying direction; the bottle separating unit is connected to the rear end of the shaping unit. The shaping unit can extrude and adjust the state of the plastic bottles, keep the states of the plastic bottles consistent in the conveying direction, and separate the plastic bottles by a certain distance.

[0004] Preferably, the shaping unit includes a first conveying component and a second conveying component which are relatively arranged on both sides of the conveying chain plate. The first conveying component and the second conveying component extrude the bottle bodies of the plastic bottles entering between them, adjust the state of the plastic bottles and convey them to the bottle separating unit.

[0005] Preferably, the feeding ends of the first conveying component and the second conveying component both expand outwards.

[0006] More preferably, the first conveying component and the second conveying component both include shaping conveyor belts, and a plurality of supporting rollers for supporting the rotation of the shaping conveyor belts. The supporting rollers are driven by power components.

[0007] More preferably, it further includes a guide plate, which is arranged between the corresponding supporting rollers and is used to support the inner side of the shaping conveyor belt.

[0008] Preferably, the bottle separating unit includes a separating mechanism and a bottle blocking mechanism, and the separating mechanism and the bottle blocking mechanism are respectively arranged on two opposite sides of the conveying chain plate.

[0009] More preferably, the separating mechanism includes a synchronous belt and pulleys for supporting the rotation of the synchronous belt, and a plurality of baffles are evenly distributed on the synchronous belt.

[0010] Preferably, it further includes a transition assembly, and the transition assembly connects the shaping unit and the bottle separating unit, and is used for restricting the state of the plastic bottles after being shaped by the shaping unit and separated by a certain distance, and stably conveying them to the bottle separating unit.

[0011] More preferably, the transition assembly is located at the bottom and / or top of the first conveying assembly and / or the second conveying assembly, and the shaping unit includes a transition belt, and the transition belt can rotate following the first conveying assembly or the second conveying assembly.

[0012] The beneficial effects of this application are as follows: In this application, the first conveying assembly and the second conveying assembly relatively arranged on two sides of the feeding end of the conveying chain plate can shape the plastic bottles conveyed by the conveying chain plate. When the plastic bottles pass between the first conveying assembly and the second conveying assembly, the two will squeeze the plastic bottles to adjust the posture of the bottle body, ensure that the states of the plastic bottles are consistent, so as to facilitate subsequent grasping without missing any, and there is no need for manual intervention, with high automation degree. At the same time, the plastic bottles can be separated by a certain distance to avoid the plastic bottles after shaping sticking together and affecting the product quality.

[0013] On this basis, a transition assembly is provided between the shaping unit and the bottle separating unit. Through the transition assembly, it can be ensured that during the process of the plastic bottles transitioning from the shaping unit to the bottle separating unit, the self-state of the plastic bottles will not change, such as the plastic bottles will not rotate and remain parallel to the conveying direction, which is convenient for smoothly entering the bottle separating unit.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the drawings of this application. Obviously, the described embodiments of this application are only partial embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0017] As Figure 1 , in the existing plastic bottle loading equipment, the positions between the fixtures A1 are fixed, and there is a certain distance L1 between the fixtures 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 fixtures A1 are filled with the gaps, they need to move a long distance L4 to place materials again, thereby affecting the placement efficiency of the plastic bottles; even if the distance L1 between the fixtures A1 is reduced, it is still necessary to provide a moving space L3 when the fixtures 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.

[0018] Refer to Figures 2 to 9 , and further elaborate on this application in detail: Combined with Figure 2 , a fully automatic plastic bottle loading equipment includes a frame 00 and a tray feeding device 4 for supplying the 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 loading efficiency.

[0019] The 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 arrange 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.

[0020] 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. The driving mechanism 22 can be driven by a linear driving mechanism or a robotic arm.

[0021] 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 at least two rows of picked plastic bottles A3, that is, reduce the distance L1 between the two rows of plastic bottles A3, and thus 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 tray loading efficiency. For example Figure 9 , at the same time, it can avoid the excessive spacing 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.

[0022] 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 separate from each other. Each clamping component (22A or 22B) can pick up a single row of plastic bottles A3. The distance adjusting mechanism 24 can be a cylinder. Of course, it can also be other linear driving mechanisms, such as a lead screw mechanism, etc.

[0023] Each clamping component includes at least one jaw component 221 for picking up the plastic bottles 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.

[0024] Combined with Figure 4 , in an embodiment, in order to avoid the inclination of the picked plastic bottles A3; a sorting component 23 for restricting the position of the picked plastic bottles 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 bottles A3, the plastic bottles A3 pass through the sorting component 23 and are clamped by the jaw component 221.

[0025] The sorting component 23 includes a component that can move along the z-axis direction ( Figure 4Move the limit frame in the up and down direction (the middle is the up and down direction) to ensure that the state of the whole row of plastic bottles A3 picked up is consistent, avoid tilting of the plastic bottles A3, so as to facilitate subsequent smooth placement between two adjacent partitions in the tray A2.

[0026] Since the temperature of the body of the plastic bottle A3 is high after filling, the plastic bottles A3 are crowded with each other during the conveying process, which will cause the plastic bottles A3 to be deformed or stuck together, and the body of the bottle will rotate, resulting in the bottle mouth and the bottle body not being on the same straight line.

[0027] In order to avoid the rotation of the body of the plastic bottle A3 caused by the crowding of the plastic bottles A3 during the conveying process, the bottle mouths of the plastic bottles A3 not being on the same straight line, the sticking phenomenon between the plastic bottles A3 or the phenomenon of the plastic bottles A3 having a crooked neck; combined with Figure 6 , the plastic bottle feeding device 3 includes at least one conveying chain plate 31 for conveying plastic bottles along the conveying direction ( Figure 6 In the middle, it is from left to right), and a bottle sorting and arranging device arranged on the conveying chain plate 31; in this embodiment, there are two conveying chain plates 31, the conveying chain plates 31 are arranged in parallel between them, and are matched with the picking mechanism 22, and the conveying chain plates 31 are synchronously driven between them; of course, the conveying chain plates 31 can also be set to more than two according to needs, and the conveying chain plates 31 can be respectively driven to convey plastic bottles.

[0028] The bottle sorting and arranging device includes a shaping unit 32 and a bottle sorting unit arranged on the conveying chain plate 31 in sequence along the conveying direction; the bottle sorting unit is connected to the rear end of the shaping unit 32; Combined with Figure 6 , the shaping unit 32 can squeeze and adjust the state of the plastic bottles to ensure that the state of the plastic bottles in the conveying direction is consistent, that is, adjust the plastic bottles A3 whose bodies rotate during the conveying process, so that the bottle mouths of the whole row of plastic bottles A3 on the conveying chain plate 31 are on the same straight line, so as to facilitate subsequent picking of the whole row of plastic bottles A3 by the picking mechanism 22 without missing grabs. Combined with Figure 8 , at the same time, the shaping unit 32 can separate the plastic bottles by a certain distance X, and separate the plastic bottles by the speed difference between the shaping unit 32 and the conveying chain plate 31, so as to avoid the shaped plastic bottles sticking together tightly and improve the product quality.

[0029] Combined with Figure 6, the bottle separation unit includes a separation mechanism 33 and a bottle blocking mechanism. The separation mechanism 33 and the bottle blocking mechanism 34 are respectively arranged on both sides of the conveying chain plate 31 opposite to each other, and the separation mechanism 33 and the bottle blocking mechanism 34 are connected to the rear end of the shaping unit 32; the separation mechanism 33 is used to separate the plastic bottles A3 to prevent the plastic bottles A3 from crowding together; the bottle blocking mechanism 34 includes a baffle, which is used to cooperate with the separation mechanism 33 to block the plastic bottles A3 and prevent the plastic bottles A3 from shaking and falling off the conveying chain plate 31 during the conveying process.

[0030] Combined with Figure 7 , wherein, the separation mechanism 33 includes a rotatable synchronous belt 331, and a plurality of baffles 330 are evenly distributed on the synchronous belt 331; wherein, the synchronous belt 331 is supported by a belt pulley 332, and the belt pulley 332 is driven by a motor to drive the synchronous belt 331 to rotate.

[0031] Combined with Figure 6 , the shaping unit 32 includes a first conveying component 321 and a second conveying component 322 which are respectively arranged on both sides of the conveying chain plate 31 opposite to each other. The first conveying component 321 and the second conveying component 322 convey and squeeze the bottle body of the plastic bottle A3 entering between them, straighten the mouth of the plastic bottle A3 with a crooked neck by squeezing the bottle body, and at the same time straighten the rotating plastic bottle A3 to ensure that the bottle body and the bottle mouth are on the same straight line, and convey the plastic bottle A3 to the side of the separation mechanism 33.

[0032] When the number of plastic bottles on the separation mechanism 33 reaches the upper limit, the shaping unit 32 stops working, can block the plastic bottles on the conveying chain plate 31, and stops conveying plastic bottles to the separation mechanism 33.

[0033] Combined with Figure 6 , the feeding ends ( Figure 6 the left end in the figure) 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 an "eight" shape towards the feeding end side of the conveying chain plate 31, which can guide the plastic bottle A3 to smoothly enter the shaping unit 32, prevent the rotated plastic bottle A3 from getting stuck at the feeding end of the shaping unit 32, and adjust the bottle body of the plastic bottle A3 during the conveying process.

[0034] Combined with Figure 7 and Figure 8, both the first conveying assembly 321 and the second conveying assembly 322 include a power component and a plurality of support rollers 3212. An 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.

[0035] In this application, the first conveying assembly 321 and the second conveying assembly 322 which are oppositely arranged on both sides of the feeding end of the conveying chain plate 31 can shape the plastic bottles conveyed by the conveying chain plate 31. When the plastic bottles pass between the first conveying assembly 321 and the second conveying assembly 322, the two will clamp the plastic bottles, adjust the posture of the bottle body, ensure that the states of the plastic bottles are consistent, so as to facilitate subsequent picking, and there is no need for manual intervention, with a high degree of automation.

[0036] Combined Figure 8 , in this embodiment, a transition assembly is connected between the first conveying assembly 321 and the separating mechanism 33. The transition assembly 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 assembly 321 and the second conveying assembly 322, and stably convey it to the separating mechanism 33, avoiding the rotation of the plastic bottle after leaving the shaping unit 32 and the change of the plastic bottle state, so that the baffle 330 can be inserted into the gap X to pick up the plastic bottle, and at the same time, it also avoids the adhesion of the plastic bottles A3 to each other.

[0037] The transition assembly includes a transition belt 323 that can rotate following the first conveying assembly 321; in this embodiment, the transition belt 323 is sleeved outside the support rollers 3212 and the belt pulley 332, and the transition belt 323 rotates synchronously with the shaping conveyor belt 3211. The transition assembly is arranged at the bottom of the first conveying assembly 321; of course, the transition assembly can also be arranged at the top of the first conveying assembly 321, or both the top and bottom of the first conveying assembly 321 are provided with the transition assembly; the transition assembly can also rotate following the synchronous belt 331 or be driven by an independent motor.

[0038] In an embodiment not shown, the transition assembly can also be arranged at the bottom and / or top of the second conveying assembly 322; or both the top and / or bottom of the first conveying assembly 321 and the second conveying assembly 322 are provided with the transition assembly.

[0039] During operation, the plastic bottle A3 passes through the feeding end of the conveying chain plate 31 ( Figure 6(with the left end in the middle) After being shaped and separated by the shaping unit 32 in sequence, the transition assembly conveys the adjusted plastic bottles A3 to the separation mechanism 33 one by one. After receiving the sorted plastic bottles A3, the separation mechanism 33 arranges the plastic bottles A3 at intervals one by one to prevent the plastic bottles A3 from being crowded together and causing the bottle body to deform.

[0040] Through the transition assembly, it can be ensured that the state of the plastic bottle itself will not change during the process of the plastic bottle transitioning to the bottle separation unit when it exits the shaping unit 32.
