Description

Technical Field

[0001] The present invention relates to the technical field of automatic packaging equipment, and in particular to a fully automatic filling and rolling integrated machine. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid made of resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. The existing paint filling is to send the mixed paint into the material tank, and then divide the paint in the material tank into the filling barrel that is conveyed. After the filling is completed, the filling barrel is transported to the capping area for capping. A similar structure is provided in the Chinese utility model patent with the authorization announcement number CN 218055874 U. In this structure, the barrel cover needs to be manually placed on the filling barrel after the filling is completed, and then the capping is achieved by manually pressing the tool. Obviously, this type of structure can no longer meet the production capacity requirements. With the rapid development of automated production, processes including cap delivery and cap pressing can be automated. However, the integrated machine is huge and cannot be used in workshops with limited space. For packaging sites in small workshops, only packaging machines with separate filling and cap pressing can be used. This packaging method results in a lot of time being wasted on turnover, and has limited improvement on the overall packaging efficiency. Summary of the invention

[0023] By adopting the above technical solution, the present invention has the following beneficial effects:

[0024] (1) The present invention integrates the filling part, the upper cover part and the capping part in sequence on the side of the conveying part along the conveying direction to realize multi-functions in one, and is provided with two weighing parts, one of which weighs the weight of the filled paint to realize automatic filling and weighing, and the other performs re-inspection before capping to ensure that the weight of the paint in the barrel meets the standard and avoid rework caused by unqualified weight after capping. The upper cover part is composed of an inclined cover bin part and a flippable cover feeding part, which realizes automatic cap feeding while saving the upper cover space. The overall layout is more reasonable, realizing the miniaturization of the whole machine, improving the filling production efficiency and being able to adapt to production workshops of more scales.

[0025] (2) The present invention cleverly designs the structure of the discharge part and realizes the formation of two different passages in the discharge part through a switching mechanism. Compared with the traditional pipeline structure, the passage size is significantly increased, and the suction of the piston part can achieve a very high suction and discharge speed, thereby realizing the improvement of the filling speed. The overall filling efficiency can be improved without setting up multiple filling heads.

[0026] (3) The present invention utilizes a switching cylinder to drive the two plugging blocks on the guide rod to rise and fall synchronously. By designing the relative positions of the two plugging blocks and the channel between the two chambers and the outlet of the discharge part, the outlet can be sealed, the channel is opened, the piston part sucks in the feed, the outlet is opened, the channel is sealed, and the piston part pushes out the feed. The structure is simple and the control is convenient.

[0027] (4) The present invention drives the piston rod of the piston cylinder to reciprocate by means of a servo motor screw module, thereby improving the movement accuracy of the piston rod, thereby ensuring the accuracy of material suction, facilitating the control of filling accuracy, and adjusting the size of the piston cylinder body to achieve feed and discharge speed adjustment.

[0028] (5) The size of the cover passage of the present invention is adjustable to meet the conveying requirements of barrel covers of different sizes. The stacked barrel covers are supported by the cover dragging mechanism, and the previous barrel cover is clamped by the first cover clamping mechanism. When the cover dragging mechanism is opened, the barrel covers naturally flow to the cover delivery part to realize the cover-adding one by one.

[0029] (6) The present invention adds a second lid clamping mechanism, which can share part of the weight by clamping the barrel lid, thereby avoiding a large number of stacked barrel lids resulting in a large weight. The first lid clamping mechanism is limited by the size of the barrel lid and the clamping thickness is too thin to clamp the barrel lid, thereby improving the stability of the lid delivery.

[0030] (7) The present invention drives the turning frame to turn by driving the connecting rod through the cylinder, thereby turning the cap suction mechanism installed on the turning frame, thereby transferring the barrel cap at the end of the upper cover part to the filling barrel below. The structural design is ingenious, and only one cylinder is needed to realize the cap feeding action, thereby achieving high-speed cap removal and placement, thereby improving production efficiency.

[0031] (8) The capping part of the present invention drives the pressure head to rise and fall through the capping cylinder, thereby realizing automatic capping. The structure has a quick action response. The pressure head and the capping cylinder are detachably connected. By replacing pressure heads of different sizes, barrel covers of different sizes can be satisfied, and the versatility is better.

[0032] (9) The present invention realizes the synchronous lifting and lowering of the conveying part, the filling part, the upper cover part and the rolling cover part by setting a lifting platform, adapting to the filling requirements of filling heads of different heights and improving the production change efficiency.

[0033] (10) The present invention provides a chassis to cover various functional components, thereby improving the safety of equipment use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] (Example 1)

[0044] like Figures 1 to 5 The fully automatic filling and rolling machine shown comprises a conveying part 1, a filling part 2, an upper cover part 3, a capping part 4 and a weighing part 5, wherein the filling part 2, the upper cover part 3 and the capping part 4 are sequentially arranged on the side of the conveying part 1 along the conveying direction to form a filling station, a capping station and a capping station, and the filling barrel is conveyed to each station for automatic filling production by the conveying part 1. There are two weighing parts 5, which are installed on the conveying part 1 and are respectively located directly below the filling part 2 and between the upper cover part 3 and the capping part 4. The two weighing parts are used for filling weighing and filling re-inspection respectively. The upper cover part 3 comprises an inclined cover bin part and a cover delivery part arranged at the lower end of the cover bin part. The cover bin part is used to place the stacked barrel covers and deliver the barrel covers one by one to the lower end of the cover bin part. The cover delivery part transfers the barrel covers at the lower end of the cover bin part to the top of the conveyed filling barrel through a flipping action, and then presses down the barrel cover through the capping part 4 so that the barrel cover is buckled on the filling barrel. The overall structure is compact and the layout is more reasonable, which realizes the miniaturization of the whole machine and integrates the filling and rolling functions into one. It improves the filling production efficiency and can adapt to production workshops of larger scales.

[0045] Specifically, in order to improve the safety of filling production, the present embodiment is provided with a chassis 6, and the conveying part 1, the filling part 2, the upper cover part 3 and the capping part 4 are all arranged in the chassis 6. The top of the chassis 6 is provided with notches corresponding to the filling part 2 and the upper cover part 3, and the side is provided with windows respectively facing the entrance and exit of the conveying part 1.

[0046] The conveying part 1 includes a chain conveyor 1-1 and a railing part 1-2 arranged on the conveying plane of the chain conveyor 1-1. The railing part 1-2 includes a fixed first handwheel screw assembly 1-2-1 and a first guardrail 1-2-2 arranged oppositely. The two first guardrails 1-2-2 are spaced apart by the first handwheel screw assembly 1-2-1 to meet the linear conveying requirements of filling barrels of different specifications. Positioning blocks 1-2-3 with equal spacing are detachably installed on the conveying surface of the chain conveyor 1-1 by screws, thereby separating adjacent filling barrels and improving the conveying position accuracy of the filling barrels. At the same time, the weighing surface of the weighing part 5 is provided with a slot aligned with the positioning block 1-2-3, and the slot runs through the weighing surface along the conveying direction to ensure that the positioning block will not interfere with the weighing part 5 when moving with the chain conveyor 1-1.

[0047] In order to realize the rapid change of filling of filling barrels of different height specifications, in this embodiment, a lifting platform 7 is fixedly provided on the side of the conveying part 1, and the filling part 2, the upper cover part 3 and the rolling cover part 4 are all installed on the lifting platform 7 to realize synchronous lifting and adjustment, thereby improving the switching efficiency during the production change without repeated debugging.

[0048] The conveying front end of the filling part 2 is provided with a small material part 8 installed on the side of the conveying part 1. The small material part 8 is also fixed on the lifting platform 7 and is used to add various additives before filling. The filling part 2 includes a first frame 2-1, a material box 2-2, a material discharge part 2-3 and a piston part 2-4. The first frame 2-1 is fixed on the lifting platform 7. The material box 2-2, the material discharge part 2-3 and the piston part 2-4 are all fixed on the first frame 2-1. The material discharge part 2-3 is provided with a first chamber 2-3-1, a second chamber 2-3-2 and a switching mechanism. The switching mechanism includes a switching cylinder 2-3-3, a guide rod 2-3-4, a first plugging block 2-3-5 and a second plugging block 2-3-6. The material box 2-2 is used to store paint, the first chamber 2-3-1 is connected to the material box 2-2, the second chamber 2-3-2 is connected and arranged below the first chamber 2-3-1 and its outlet faces the conveying part, the switching cylinder 2-3-3 is fixedly installed on the top of the first chamber 2-3-1, the piston rod is coaxially fixedly connected with the guide rod 2-3-4 sealably inserted in the first chamber, the lower end of the guide rod 2-3-4 extends to the second chamber 2-3-2, the first plugging block 2-3-5 and the second plugging block 2-3-6 are coaxially fixedly installed on the guide rod 2-3-4 from top to bottom.

[0049] The piston part 2-4 includes a piston cylinder 2-4-1 and a servo motor screw module 2-4-2 fixedly mounted on the first frame 2-1. The cylinder body of the piston cylinder 2-4-1 is directly connected to the side wall of the second chamber 2-3-2 and is connected to the inner cavity. The piston rod is fixedly connected to the moving block of the servo motor screw module 2-4-2. The servo motor screw module 2-4-2 is used to drive the piston rod of the piston cylinder to reciprocate, thereby improving the movement accuracy of the piston rod, thereby ensuring the accuracy of material suction, facilitating the control of filling accuracy, and improving efficiency by selecting a piston cylinder with a larger cylinder body to increase the feeding and discharging speeds.

[0050] When the switching mechanism is in the first state, the first plugging block 2-3-5 is located in the second chamber 2-3-2, and the second plugging block 2-3-6 blocks the outlet of the second chamber 2-3-2, so that the material box 2-2, the first chamber 2-3-1 and the second chamber 2-3-2 form a sealed space, and the piston of the piston cylinder 2-4-1 is sucked to achieve the paint in the material box 2-2 to quickly enter the unloading part. When the switching mechanism is in the second state, the first plugging block 2-3-5 is located at the connection between the first chamber 2-3-1 and the second chamber 2-3-2 and separates the two chambers, and the second plugging block 2-3-6 is located above the outlet of the second chamber 2-3-1, and is pushed out by the piston of the piston cylinder 2-4-1, so that the paint in the second chamber and the piston cylinder is quickly injected into the filling barrel. A single cylinder is used to complete the three-way conversion, and the passage is very large, which can achieve a very large extraction and discharge speed, significantly improving the filling speed.

[0051] Taking into account that the paint itself has a pungent odor, in this embodiment, a baffle 2-5 suitable for covering the barrel mouth of the filling barrel is fixedly connected to the bottom of the discharge part 2-3, and a suction port 2-5-1 located in the barrel mouth area is provided on the baffle 2-5. The suction port is connected to an external negative pressure filtration system through a pipeline. During filling, the odor generated during the filling of the paint can be purified to keep the workshop environment comfortable.

[0052] The cover bin part includes a material rack 3-1 which is arranged upwardly and obliquely along the conveying direction. The material rack 3-1 is provided with an upper cover channel with adjustable size to meet the feeding of barrel covers of different specifications. Specifically, the upper cover channel is composed of a second guardrail 3-2 which is arranged oppositely and a third guardrail 3-3 which is arranged parallelly between the two guardrails. The side and bottom of the material rack 3-1 are respectively installed with a second screw adjustment assembly 3-4 and a third screw adjustment assembly 3-5. The two second guardrails 3-2 are arranged parallelly on the material rack 3-1 with adjustable spacing through the second screw adjustment assembly 3-4. The third guardrail is adjustably installed on the material rack 3-1 in a direction perpendicular to the plane where the material rack is located through the third screw adjustment assembly 3-5. A cover separation mechanism is provided at the lower end of the upper cover channel. The cover separation mechanism includes a first cover clamping mechanism 3-6 and a cover dragging mechanism 3-7 which are arranged in an aligned manner from top to bottom along the oblique direction of the material rack 3-1. The first cover clamping mechanism 3-6 and the cover dragging mechanism 3-7 are respectively used to clamp and drag the barrel covers located at the second to last position and the last position. Specifically, a mounting seat 3-8 is fixedly provided at the bottom of the second guardrail 3-2, and an intermediate plate 3-9 is adjustably provided on the mounting seat 3-8 along the length direction of the second guardrail 3-2. The first cover clamping mechanism 3-6 includes a first cover clamping cylinder 3-6-1 respectively fixed on two intermediate plates 3-9, and the piston rod of the first cover clamping cylinder 3-6-1 is arranged toward the stacked barrel covers and is fixedly connected to a clamping plate 3-6-2, and an arc-shaped notch is provided on the side of the clamping plate 3-6-2 facing the barrel covers to increase the contact area with the barrel covers. The cover dragging mechanism 3-7 includes a cover dragging cylinder 3-7-1 respectively fixed on two mounting seats 3-8, and the piston rod of the cover dragging cylinder 3-7-1 is arranged toward the stacked barrel covers and is fixedly connected to a supporting plate 3-7-2. The end barrel cover is dragged by the cover dragging mechanism 3-7, and the previous barrel cover is clamped by the first cover clamping mechanism 3-6. When the cover dragging mechanism is opened, the barrel cover is separated from the cover bin part and naturally flows to the cover delivery part to realize the one-by-one cover application.

[0053] Considering that there are many barrel covers and the weight is large after stacking, and limited by the flat shape of the barrel covers, the thickness of the clamping plate 3-6-2 of the first clamping cover mechanism is thin, and the clamping force is insufficient. In this embodiment, a second clamping cover mechanism 3-10 is provided above the first clamping cover mechanism 3-6 along the tilting direction of the material rack, so as to share part of the weight by clamping the barrel cover and improve the stability of the cover delivery. Specifically, a plurality of mounting holes are provided along the length direction near the lower end of the second guardrail 3-2, and the second clamping cover mechanism 3-10 includes a second clamping cover cylinder 3-10-1 adjustably mounted on the second guardrail through bolts and mounting holes, and the piston rod of the second clamping cover cylinder 3-10-1 is arranged toward the barrel cover away from the stack and is fixedly connected with a clamping block 3-10-2, which extends to the upper cover channel and is not restricted in thickness relative to the clamping plate 3-6-2, thereby ensuring sufficient clamping force.

[0054] The cover feeding part includes a connecting plate 3-11 and a rotating shaft 3-12 which are respectively fixedly and rotatably mounted on the lower end of the material rack 3-1. The end of the connecting plate 3-11 is inclined upwardly arranged in the opposite direction of conveying and is rotatably mounted with a sliding block. The sliding block is matched with a linear guide rail 3-13. A turning frame 3-14 is fixedly mounted on the rotating shaft 3-12. The other side of the turning frame 3-14 is fixedly connected to the linear guide rail and a cover suction part 3-15 is fixedly mounted thereon. A turning cylinder 3-16 is hinged on the side of the material rack 3-1. The piston rod of the turning cylinder 3-16 is hinged with a connecting rod 3-17. The connecting rod 3-17 is arranged parallel to the connecting plate and is fixedly connected to the rotating shaft 3-12. The turning cylinder 3-16 drives the connecting rod 3-17 to rotate the rotating shaft, thereby driving the turning frame 3-14 to turn, so that the cover suction part 3-15 faces the barrel cover at the bottom of the cover bin part, thereby sucking the barrel cover, and the turning cylinder 3-16 is reset, so that the cover suction part 3-15 faces the filling barrel on the conveying part, and the barrel cover is automatically delivered. The structural design is ingenious, and only one cylinder is needed to realize the cover delivery action, so that high-speed cover removal and placement can be achieved, and production efficiency is improved.

[0055] The capping section 4 includes a second frame 4-1 fixedly mounted on the lifting platform, on which a capping cylinder 4-2 is fixedly mounted, a piston rod of the capping cylinder 4-2 is vertically downwardly arranged and detachably connected to a pressure head 4-3, which is located directly above the conveying section and presses the barrel cover placed on the filling barrel to achieve automatic capping.

[0056] The working process of this embodiment is as follows: the empty filling barrel first arrives at the bottom of the small material part 8 driven by the conveying part for small material filling, and then reaches the filling part 2 for paint filling. At the same time, the weighing part works. When the weight reaches the set value, the filling stops, and the filling barrel continues to flow to the upper cover part 3 to complete the automatic cover, and is re-inspected by another weighing part. The filling barrels with qualified weight are automatically capped in the capping part 4, and those that fail to meet the requirements are not capped to avoid destructive rework.

[0057] The present invention integrates the filling part, the upper cover part and the capping part in sequence on the side of the conveying part along the conveying direction to realize multi-functions in one, and is provided with two weighing parts, one of which weighs the weight of the filled paint to realize automatic filling and weighing, and the other performs re-inspection before capping to ensure that the weight of the paint in the barrel meets the standard and avoids the need for capping and rework due to unqualified weight after capping. The upper cover part is composed of an inclined cover bin part and a flippable cover feeding part, which realizes automatic cap feeding while saving upper cover space, and the overall layout is more reasonable, realizing the miniaturization of the whole machine, improving the filling production efficiency and being able to adapt to production workshops of more scales.
