Description

Technical Field

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

[0002] Due to their light weight, non-fragility, good chemical stability, strong sealing performance, etc., plastic bottles are widely used in the pharmaceutical field. Due to different uses and requirements, the specifications of plastic bottles show a diverse range, generally including plastic bottles of different sizes such as 100 ml and 250 ml.

[0003] Currently, there are two ways to palletize plastic bottles. One is a palletizing machine with a publication number of CN213893176U, which pushes rows of plastic bottles onto the sterilization tray one by one until the sterilization tray is full to complete palletizing. Although more plastic bottles can be placed in the sterilization tray in this way, since there are no partitions in the sterilization tray, the plastic bottles are in contact and extrusion with each other, which easily causes the plastic bottles to deform and affects the product quality.

[0004] Such as Figure 1 , the other is that there are several partitions in the sterilization tray. The multi-row clamps A1 on the picking mechanism pick up multiple rows of plastic bottles A3 at one time, and then place the picked multiple rows of plastic bottles A3 between the corresponding partitions. Since the positions between the clamps A1 are fixed and there is a certain distance L1 between adjacent clamps A1, the distance L2 between the partitions in the tray A2 (sterilization tray) is relatively large. Therefore, the number of plastic bottles A3 palletized in the limited tray A2 is limited and difficult to further increase. Summary of the Invention

[0005] In view of the above defects, this application provides a multi-row plastic bottle picking and palletizing device, which can place more plastic bottles in a limited tray on the premise of ensuring that the whole rows of plastic bottles do not contact and extrude with each other, improving the palletizing efficiency. The following technical solutions are adopted: The multi-row plastic bottle picking and palletizing device includes a driving mechanism and a picking mechanism arranged on the driving mechanism. The driving mechanism is used to drive the picking mechanism to move; The picking mechanism includes at least two clamping components, which are arranged in parallel between the clamping components, and each clamping component can pick up a single row of plastic bottles; The picking distance between the clamping components can be adjusted. After picking, the distance between the picked whole rows of plastic bottles can be shortened.

[0006] Preferably, it further includes a distance adjusting mechanism, which is used to adjust the picking distance between the clamping components.

[0007] Preferably, each of the clamping components includes a carrier plate connected to the driving mechanism, and at least one jaw component provided on the carrier plate, and the jaw component is used for picking up plastic bottles.

[0008] More preferably, the jaw component includes a pair of openable and closable clamping plates, and the clamping plates are used for grasping the bottle mouth of the plastic bottle.

[0009] More preferably, it further includes a driving component, the driving component includes a mounting plate and a driving cylinder, a clamping block is provided at the power end of the driving cylinder, and clamping grooves for placing the clamping block are respectively provided on the inner sides of the clamping plates.

[0010] Preferably, it further includes an arrangement component, the arrangement component is used for restricting the positions of the whole row of plastic bottles picked up by the clamping components, and the arrangement component is attached to the clamping components; More preferably, the arrangement component includes a limiting frame capable of moving along the z-axis direction, the limiting frame has a frame structure, and the limiting frame is connected to the bottom of the clamping components.

[0011] More preferably, when there are at least three clamping components, any one of the clamping components is a first clamping component connected to the driving mechanism, and the remaining clamping components are second clamping components slidably connected to the driving mechanism, and the second clamping components are driven by the distance adjustment mechanism to move towards the first clamping component side.

[0012] The beneficial effects of the present application compared with the prior art are as follows: Based on a tray provided with partitions, the present application can control the clamping components to approach or move away from each other through a distance adjustment mechanism on the premise of ensuring that the whole row of plastic bottles will not be crowded or deformed, and can pick up the whole row of plastic bottles with different spacings. When placing the plastic bottles, the spacing between several whole rows of picked-up plastic bottles can be adjusted. In this way, the distance between the partitions in the tray can be smaller. Therefore, more plastic bottles can be placed, and at the same time, it can be applicable to pick up the whole row of plastic bottles with different spacings and place them in a tray with partitions of different spacings.

[0013] By adjusting the spacing between the clamping components, it is ensured that there is a row of gaps between several rows of picked-up plastic bottles, which can avoid the long-distance movement of the picking mechanism, thereby improving the loading efficiency.

Detailed implementation manners

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

[0017] Refer to Figures 2 to 9 for a further detailed description of the present application: In combination with Figure 2 a full-automatic plastic bottle tray loading device includes a frame 00 and a tray feeding device 4 for supplying trays 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 trays A2 synchronously or alternately to improve the tray loading efficiency.

[0018] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 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. Among them, both the first clamping component 22A and the second clamping component 22B are one. After the first clamping component 22A and the second clamping component 22B both 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 and reduce the distance between them. The distance adjusting mechanism 24 can be a cylinder. The cylinder is provided 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.

[0023] In an embodiment not shown, the clamping components can also be movably arranged on the driving mechanism 21, and the distance adjusting mechanism 24 is used to drive the clamping components to approach or move away from each other.

[0024] In some embodiments, there may be three clamping components. The first clamping component 22A may be located in the middle, and the second clamping components 22B may be 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, it is also possible that any one of the two sides is the first clamping component 22A, and the other 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 provided to adjust the distance between them.

[0025] 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 row of plastic bottles, and further 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. For example Figure 9 , at the same time, it can avoid too large a distance between the picked-up row of plastic bottles placed in the tray A2, reduce the moving distance L4 of the picking mechanism, and improve the loading efficiency.

[0026] 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 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. In this embodiment, the cylinder is arranged on the mounting frame 2211, 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.

[0027] 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. 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.

[0028] Both the first linear drive assembly 211 and the second linear drive assembly 212 include a drive component and a reciprocating movement component. The drive component is used to drive the reciprocating component to drive the picking mechanism 22 to move. In this embodiment, the drive component is a motor, and the reciprocating movement component can be a rack and pinion mechanism or a lead screw mechanism, etc. Of course, in an embodiment not shown, the drive mechanism 21 can be a robotic arm.

[0029] Combined with Figure 4 , in an embodiment, in order to prevent the body of the picked plastic bottle A3 from tilting, there is also a sorting assembly 23 for restricting the position of the picked plastic bottle A3. The sorting assembly 23 is attached to the clamping assembly. Among them, the sorting assembly 23 can be provided at the bottom of the clamping assembly. When picking the plastic bottle A3, the plastic bottle A3 passes through the sorting assembly 23 and is clamped by the jaw assembly 221.

[0030] The sorting assembly 23 includes a limit frame that can move along the z-axis direction ( Figure 4 which is the up and down direction in this case). Among them, the limit frame can be connected to the jaw assembly 221 through a cylinder, and the cylinder is used to drive the limit frame to move along the z-axis direction to sort the state of the plastic bottle A3. The limit frame has a frame structure and is connected to the bottom of the jaw assembly 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.

[0031] Combined with Figure 6 , the feeding device 3 includes at least two parallel conveyor chain plates 31. The conveyor chain plates 31 are used to convey the plastic bottle A3 and 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 synchronously driven. Of course, the conveyor chain plates 31 can also be set to more than two according to requirements, and the conveyor chain plates 31 can be driven separately to convey the plastic bottles.

[0032] 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 bottle A3 to be deformed or adhered together, and the body of the bottle to rotate, resulting in the bottle mouth and the bottle body not being on the same straight line.

[0033] In order to prevent the plastic bottle A3 from being crowded during the conveying process, resulting in the rotation of the body of the plastic bottle A3, the bottle mouth of the plastic bottle A3 not being on the same straight line, the adhesion between the plastic bottles A3, or the phenomenon of the plastic bottle A3 having a crooked neck; combined with Figure 6 , there is also a component provided at the feeding end of the feeding device 3 ( Figure 6A shaping mechanism 32 (with the left end in the middle) that can extrude and adjust the state of the plastic bottle to ensure that the state of the plastic bottle remains consistent, that is, adjust the plastic bottle A3 whose body rotates during transportation so that the mouths of the whole row of plastic bottles A3 on the conveying 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 grabs. Combined with Figure 8 Meanwhile, the shaping mechanism 32 can separate the plastic bottles by a certain distance X, and the separation of the plastic bottles is achieved through the speed difference between the shaping mechanism 32 and the conveying chain plate.

[0034] 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 conveying 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 crowding together; the bottle blocking mechanism 34 includes a baffle for cooperating with the separating 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 transportation.

[0035] Combined with Figure 7 Among them, 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.

[0036] Combined with Figure 6 The shaping mechanism 32 includes a first conveying component 321 and a second conveying component 322 that are respectively arranged on both sides of the conveying chain plate 31 in a relatively arranged manner. The first conveying component 321 and the second conveying component 322 convey and extrude the body of the plastic bottle A3 entering between them, straighten the mouth of the plastic bottle A3 with a crooked neck by extruding the body, and at the same time straighten the rotating plastic bottle A3 to ensure that the body and the mouth are on the same straight line, and convey the plastic bottle A3 to the side of the separating mechanism 33.

[0037] 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.

[0038] Combined with Figure 7 Among them, both the first conveying component 321 and the second conveying component 322 include a rotatable shaping conveyor belt, and a guide plate is arranged inside the shaping conveyor belt, and the guide plate is used to support the inner side of the shaping conveyor belt.

[0039] Combined with Figure 7, 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 restrict 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, so as to prevent 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 prevent the plastic bottles A3 from sticking together.

[0040] The transition component includes a transition belt 323 that can rotate following the first conveying component 321; the transition belt 323 rotates synchronously with the shaping conveyor belt; the transition component is arranged at the bottom and / or the top of the first conveying component 321 and / or the second conveying component 322; of course, it can also be rotated following the synchronous belt 331 or driven by an independent motor.

[0041] During operation, the plastic bottle A3 passes through the feeding end of the conveying chain plate 31 ( Figure 6 the left end in the figure) and is successively shaped and separated by the shaping mechanism 32. The transition component conveys the adjusted plastic bottles A3 to the separating mechanism 33 one by one. After the separating mechanism 33 receives the sorted plastic bottles A3, it 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.

[0042] Combined with Figure 8 , the tray 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.

[0043] 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 no limitation is made here.

[0044] 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, and no limitation is made here.

[0045] 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 out to clamp the tray A2. Of course, it can also be clamped by rotation, such as a rotary cylinder, which is not limited here.
