Description

Technical Field

[0002] At present, in the domestic lubricating oil coating industry, since most of the packaging materials are iron barrels with eccentric barrel mouths, the sealing covers include inner plug covers and outer covers. During the filling and capping production, it is necessary to manually put the empty barrels on the conveyor line, adjust the barrel mouth position, and then manually put the inner plug or outer cover on the barrel mouth for manual capping or screwing. This operation method is not only labor-intensive, consuming a lot of manpower and financial resources, but also has low production efficiency and cannot meet the increasing filling speed.

[0019] (2) The utility model can simultaneously adjust the heights of the pre-positioning mechanism, the cap sorting mechanism, the precise positioning mechanism, the plug pressing mechanism and the outer cap screwing mechanism by setting a lifting platform, so as to meet the capping requirements of iron drums of different heights, realize rapid switching of packaging specifications, and have a wide range of applications.

[0020] (3) The utility model blocks the iron barrel by setting a barrel blocking part, thereby effectively preventing the iron barrel from entering the full-automatic capping machine before the barrel mouth is pre-positioned.

DETAILED DESCRIPTION

[0034] 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.

[0035] (Example 1)

[0036] like Figures 1 to 6The fully automatic positioning, pressing and rotating integrated machine shown includes a barrel feeding conveyor 1, a fully automatic capping machine, a capping machine 2 and a pre-positioning mechanism 3. The fully automatic capping machine includes a barrel feeding workbench 4, an inner plug pressing mechanism 5, an outer cap rotating mechanism 6, a precise positioning mechanism 7, a cap sorting mechanism 8 and a barrel rotating mechanism 9. The barrel feeding conveyor 1 and the barrel feeding workbench 4 are arranged in a straight line to convey eccentric iron barrels. The pre-positioning mechanism 3 is installed at the exit of the barrel feeding conveyor 1, and the inner plug pressing mechanism 5 and the outer cap rotating mechanism 6 are sequentially installed on the side of the barrel feeding workbench 4 along the conveying direction. There are two capping machines 2, two precise positioning mechanisms 7 and two cap sorting mechanisms 8. The two precise positioning mechanisms 7 are respectively arranged at the conveying front ends of the inner plug pressing mechanism 5 and the outer cap rotating mechanism 6. The two capping machines 2 are connected to the full-automatic capping machine, and the outlets are respectively located directly above the two cap sorting mechanisms 8. The two cap sorting mechanisms 8 are respectively installed on the sides of the inner plug pressing mechanism 5 and the outer cap rotating mechanism 6, and the outlets are respectively connected to the inner plug pressing mechanism 5 and the outer cap rotating mechanism 6, so as to transport the inner plug caps and the outer caps. There are three barrel rotating mechanisms 9, which are respectively located directly below the pre-positioning mechanism 3 and the precise positioning mechanism 7, and can be raised and lowered to penetrate the barrel delivery plane, so as to lift the delivered iron barrel upward and leave the barrel delivery plane, and realize barrel mouth positioning under the action of the pre-positioning mechanism 3 and the precise positioning mechanism 7. By optimizing the traditional barrel mouth positioning realized by one station into two stations, the residence time of a single iron barrel is saved, the overall packaging efficiency is improved, and a secondary positioning realized by the precise positioning mechanism 7 is added before screwing on the outer cap, so as to avoid the failure of screwing on the outer cap due to slight deviation after pressing the inner plug, and reduce the defective product rate.

[0037] Specifically, the barrel feed conveyor 1 adopts a roller conveyor, and the top two sides of the roller conveyor are symmetrically provided with iron barrel baffles 1-1 with adjustable spacing to ensure that iron barrels of different diameters can be transported in a straight line. The end of the iron barrel baffle 1-1 is provided with a barrel holding mechanism realized by a cylinder, which can prevent the subsequent iron barrel from being transported without controlling the start and stop of the barrel feed conveyor 1, and the structure is simple. The conveying end is provided with a barrel blocking part 1-2 that can be raised and lowered by a cylinder, which effectively prevents the iron barrel from entering the fully automatic capping machine before the barrel mouth is pre-positioned.

[0038] A lifting platform 10 is fixedly provided on the side of the barrel feeding workbench 4, wherein the pre-positioning mechanism 3, the cap sorting mechanism 8, the precise positioning mechanism 7, the inner plug pressing mechanism 5 and the outer cap screwing mechanism 6 are all installed on the lifting platform 10, which can adjust the working heights of these mechanisms at the same time to meet the capping requirements of iron barrels of different heights, realize rapid switching of packaging specifications, and has a wide range of applications.

[0039] The barrel rotating mechanism 9 includes a limiting hole 9-1 opened on the barrel delivery plane and a mounting plate 9-2 installed below the barrel delivery plane so as to be liftable by a cylinder. A barrel rotating motor 9-3 is fixedly provided at the bottom of the mounting plate 9-2. The motor shaft of the barrel rotating motor 9-3 vertically penetrates the mounting plate 9-2 and the limiting hole 9-1 and is fixedly connected to a barrel rotating plate 9-4 located above the barrel delivery plane. The pre-positioning mechanism 3 includes a first seat body 3-1 and a first barrel pressing part, the first barrel pressing part includes a first lifting cylinder 3-2, a first support plate 3-3, an elastic barrel pressing rod 3-4 and a first photoelectric detection part 3-5, wherein the first seat body 3-1 is fixedly mounted on the top of the lifting platform 10, the first lifting cylinder 3-2 is vertically fixedly mounted on the top of the first seat body 3-1, and the piston rod is vertically arranged downward and fixedly connected to the first support plate 3-3, the upper end of the elastic barrel pressing rod 3-4 is fixedly mounted on the first support plate 3-3, and the lower end is used to press the iron barrel lifted by the rotating barrel mechanism 9, the first photoelectric detection part 3-5 is fixedly mounted on the first support plate 3-3 and is located on the side of the elastic barrel pressing rod 3-4, and is used to detect the barrel mouth position. When the iron barrel is conveyed to the bottom of the pre-positioning mechanism 3, the rotating barrel mechanism 9 here is activated, and the mounting plate 9-2 rises, thereby driving the rotating barrel plate 9-4 to push the iron barrel upward. At this time, the elastic barrel pressing rod 3-4 descends to press the top surface of the barrel, fixing the iron barrel, and the iron barrel is rotated under the action of the rotating barrel motor 9-3. When the first photoelectric detection part 3-5 detects the position of the barrel mouth, it stops rotating, and the barrel mouth is rotated to the approximate position.

[0040] The barrel delivery workbench 4 includes a fixed frame 4-1, a module slide 4-2 is fixedly installed at the bottom of the frame 4-1, a bottom plate 4-3 is fixedly installed on the slider of the module slide 4-2, and support frames 4-4 are symmetrically arranged on both sides of the bottom plate 4-3. The bottoms of the two support frames 4-4 are installed on the bottom plate 4-3 through a double-headed cylinder 4-5, and a barrel clamping block 4-6 is arranged oppositely in the top gap. When the iron barrel is pre-positioned at the barrel mouth, it enters the barrel delivery workbench, and the support frames 4-4 on both sides are driven to move away from and close to each other by the double-headed cylinder 4-5, so as to fix the iron barrel by the barrel clamping block 4-6, and then the reciprocating motion of the module slide 4-2 is used to realize the step-by-step delivery of the iron barrel, and the first precise positioning, inner plug pressing, second precise positioning and outer cover screwing are carried out in sequence, with a simple structure and high conveying efficiency.

[0041] The precise positioning mechanism 7 includes a second seat body 7-1 fixedly mounted on the lifting platform 10, a second pressure barrel part 7-2 that can be raised and lowered is fixedly mounted on the top of the second seat body 7-1, and a precise positioning part that is fixedly connected to the second pressure barrel part 7-2 is provided on the side along the longitudinal sliding. The structure of the second pressure barrel part 7-2 is the same as that of the first pressure barrel part, which will not be described here. A first linear guide rail 7-3 is fixedly mounted on the side of the second seat body 7-1, and the precise positioning part includes a second support plate 7-4 that is fixedly mounted on a slider of the first linear guide rail 7-3 and connected to the second pressure barrel part 7-2 to achieve synchronous lifting, and guide rollers 7-5 are symmetrically arranged on both sides of the second support plate 7-4, and a connecting block 7-6 is fixedly mounted on the bottom, and a pressure block 7-7 is rotatably mounted on the connecting block 7-6, and a second photoelectric detection part 7-8 is fixedly mounted on the pressure block 7-7, and a detection through groove facing the second photoelectric detection part 7-8 is opened at the bottom. The position of the iron barrel is fixed and adjusted by the second barrel pressing part and the barrel rotating mechanism 9 located below. The two groups of guide rollers 7-5 of the precise positioning part use the barrel surface as a reference and cooperate with the second photoelectric detection part 7-8 to detect the precise position of the barrel mouth, so as to achieve precise adjustment of the barrel mouth position and improve the qualified rate of the cap. Since there is a height difference between the barrel mouth and the barrel surface, by installing the second photoelectric detection part 7-8 on the rotating pressing block 7-7, on the one hand, the photoelectric detection part can be protected to avoid damage by impacting the barrel mouth, and on the other hand, it can be ensured that the barrel surface is always used as a reference during the entire barrel rotating process, so as to guide the barrel rotating mechanism at the bottom to lift the barrel. In order to achieve rapid resetting of the pressing block 7-7 after rotation, reset springs 7-9 are symmetrically connected between the two sides of the pressing block 7-7 of this embodiment and the two sides of the second support plate 7-4, so as to ensure that the pressing block can be quickly reset after rotation and keep horizontal.

[0042] When the barrel mouth position of the iron barrel is accurately adjusted, it moves to the bottom of the inner plug pressing mechanism 5 and the outer cover screwing mechanism 6 under the action of the barrel feeding workbench 4 for capping. Specifically, the cap sorting mechanism 8 includes a centrifugal capping device 8-1, a cap feeding part 8-2, and a climbing plate 8-3 connected between the outlet of the centrifugal capping device 8-1 and the inlet of the cap feeding part 8-2. The cap feeding part 8-2 includes a cap feeding cylinder 8-2-1 and a second linear guide 8-2-2 fixedly mounted on the lifting platform 10. The slider of the second linear guide 8-2-2 is fixedly mounted with a cap feeding plate 8-2-3 fixedly connected to the piston rod of the cap feeding cylinder 8-2-1. The side of the cap feeding plate 8-2-3 away from the cap feeding cylinder 8-2-1 is provided with a cap feeding groove 8-2-4 facing the outlet of the climbing plate 8-3, and the side of the cap feeding groove 8-2-4 is provided with a cap feeding baffle 8-2-5. Under the action of two centrifugal capping devices 8-1, the two kinds of caps are neatly arranged and transported to the two cap feeding parts 8-2 through the climbing plate 8-3 respectively. Through the reciprocating motion of the cap feeding cylinder 8-2-1, the two kinds of caps are transported to the corresponding inner plug pressing mechanism 5 and outer cap rotating mechanism 6. When the cap feeding plate 8-2-3 is extended, the cap feeding baffle 8-2-5 just blocks the outlet of the climbing plate 8-3 to prevent the caps from being transported, thereby realizing the cap feeding one by one, and then completing the automatic capping under the action of the inner plug pressing mechanism 5 and the outer cap rotating mechanism 6.

[0043] In this embodiment, a capping machine 2 and a barrel feeding conveyor 1 are provided to convey the eccentric iron barrel after filling, as well as the inner plug cap and the outer cap, respectively. The inner plug cap and the outer cap are conveyed to the inner plug pressing mechanism 5 and the outer cap screwing mechanism 6 respectively through two cap sorting mechanisms 8. The inner plug pressing mechanism 5 and the outer cap screwing mechanism 6 perform automatic cap pressing and cap screwing respectively, and the traditional barrel mouth positioning realized by one station is optimized into two stations, that is, the barrel mouth is positioned by the cooperation of the pre-positioning mechanism 3 and the precise positioning mechanism 7, so as to save the residence time of a single iron barrel and improve the overall packaging efficiency, and a secondary positioning realized by the precise positioning mechanism 7 is added before screwing the outer cap, so as to avoid the failure of screwing the outer cap due to slight deviation after pressing the inner plug, thereby reducing the defective product rate.
