Description

Technical Field

[0001] The utility model relates to the technical field of upper cover equipment, in particular to an upper cover device. Background Art

[0002] With the changes and development of society, in the quantitative filling production of fluids, pastes, granules and powdered materials in the chemical, food, pharmaceutical and other industries, more and more full-process semi-automatic or fully automated production has been achieved, such as in the production of coatings, inks, putties, paints, latex paints, pigments, resins, sealants, additives and other products.

[0003] After these products are produced, they need to go through processes such as filling, packaging and warehousing. In the filling process, barrel-shaped containers with open tops are often used. After the above products are quantitatively filled in the barrel-shaped container, the barrel cover needs to be put on the barrel-shaped container and then sealed. In a fully automatic production line, the action of "putting the barrel cover on the barrel-shaped container" can be achieved using the capping machine in the production line.

[0004] The existing capping machine mainly uses the following structure to achieve capping. The capping machine stores the caps at the upper position of the frame, and a capping machine is set in the middle position. The barrel-shaped container moves horizontally from the bottom of the capping machine. The capping machine includes a rotary cylinder, and a mounting frame is fixedly installed on the cylinder rod of the rotary cylinder. A pair of linear telescopic cylinders are fixedly installed on the mounting frame. The cylinder rods of the two linear telescopic cylinders are installed back to back, and a set of vacuum suction cups are set on the cylinder rod of each linear telescopic cylinder. In the initial position, the linear telescopic cylinder is set vertically, and the cylinder rod of the linear telescopic cylinder located at the top is extended. The vacuum suction cup on it sucks the cap above the frame, and then the cylinder rod of the linear telescopic cylinder is retracted. In the next step, the rotary cylinder works, and its cylinder rod rotates 180°. As the cap rotates 180°, the cap becomes facing the top of the barrel-shaped container. The vacuum suction cup releases the cap, and the cap automatically falls onto the top surface of the barrel-shaped container. The barrel-shaped container with the cap is pushed to the next station, and another barrel-shaped container that needs to be capped enters the capping station. At the workstation below the machine; at the same time, the cylinder rod of the linear telescopic cylinder that rotates from the bottom to the top extends out, and the vacuum suction cup on it sucks the second cover above the frame. In the next step, the cylinder rod of the linear telescopic cylinder is retracted, and the rotary cylinder works at the same time. The cylinder rod of the rotary cylinder rotates 180° again, and the second cover rotates 180°, and the second cover becomes facing the top of the barrel container. Finally, the vacuum suction cup releases the cover, and the cover automatically falls onto the top surface of the barrel container. This cycle is repeated all the time, thereby completing the automatic continuous covering action.

[0005] The above-mentioned capping and covering operations are relatively efficient, however, the barrel container still needs to stop at the lower station of the capping machine for capping. After the capping operation is completed, it is converted from a static state to a moving state through a conveying mechanism, which takes a long time and even causes the liquid in the barrel container to splash due to the conversion of the moving state.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] In order to solve the problem in the prior art that the barrel-shaped container still needs to stop at the lower station of the capping machine to put on the cap, and after completing the capping operation, it is converted from a static state to a moving state through a conveying mechanism, which takes a long time and even causes splashing of the liquid in the barrel-shaped container due to the conversion of the moving state, the utility model provides a capping device.

[0040] like Figures 1 to 7As shown, the upper cover device includes a cover hanging and unloading mechanism 10, which has an inclined track 11 and a limit assembly 12, wherein the high end of the inclined track 11 is located below the cover placing mechanism 20, and the limit assembly 12 is arranged at the low end of the inclined track 11, and the limit assembly 12 includes two baffle structures 121, which are arranged opposite to each other and are respectively pivotally connected to the two track sides 111 of the inclined track 11, and the two baffle structures 121 have an embracing state of swinging toward each other and a back-swinging state. Expanded state; the two ends of the two baffle structures 121 are respectively a high end and a low end, and the extension direction from the high end to the low end of each baffle structure 121 is consistent with the inclination direction of the inclined track 11, and at least the low end of each baffle structure 121 is bent toward the geometric center line of the inclined track 11; wherein the two baffle structures 121 swing toward each other to form an embracing space for preventing the barrel cover 100 on the inclined track 11 from continuing to slide down, and the two baffle structures 121 swing back to back to form an expanded space for releasing the barrel cover 100.

[0041] By arranging the two baffle structures 121 of the limiting assembly 12 relatively to each other and pivotally connecting them to the two track sides 111 of the inclined track 11, respectively, the two baffle structures 121 have an embracing state of swinging toward each other and an expanding state of swinging away from each other; the two ends of the two baffle structures 121 are respectively a high end and a low end, and at the same time, the extension direction from the high end to the low end of each baffle structure 121 is consistent with the inclination direction of the inclined track 11, and at least the low end of each baffle structure 121 is bent toward the geometric center line of the inclined track 11; wherein the two baffle structures 121 swing toward each other to form an embracing space for preventing the barrel cover 100 on the inclined track 11 from continuing to slide down, and the two baffle structures 121 swing away from each other to form an expanding space for releasing the barrel cover 100.

[0042] Specifically, there is no need for the barrel-shaped container 200 to change its motion state from moving to stationary to carry out the covering, which greatly improves the covering efficiency of the covering device. In addition, the barrel cover 100 slides downward along the inclined track 11 under the action of its own gravity and is limited by the surrounding space surrounded by the two baffle structures 121. Since the two baffle structures 121 are pivotally connected to the two track sides 111 respectively, when the barrel-shaped container 200 is transported to the barrel cover 100 by the conveying mechanism 300, the lowermost part of the barrel cover 100 will be hung on the front edge of the barrel-shaped container 200, so that the barrel cover 100 is dragged along with the barrel-shaped container 200 under the traction of the barrel-shaped container 200. The container 200 moves forward together, and at the same time, the side edge of the barrel cover 100 applies an external force to the two baffle structures 121. When the traction force of the barrel-shaped container 200 on the barrel cover 100 is greater than the force of the two baffle structures 121 swinging toward each other, the two baffle structures 121 swing back and forth until the distance between the lower ends of the two baffle structures 121 is the largest. The two baffle structures 121 are in a flared state, and the two baffle structures 121 release the constraints on the barrel cover 100, so that the barrel-shaped container 200 can be covered while moving, thereby preventing the movement state of the barrel-shaped container 200 from changing and causing the liquid in the barrel-shaped container 200 to splash.

[0043] Preferably, the pivotal connections between the two baffle structures 121 and the two track sides 111 are both arranged close to the high ends of the baffle structures 121 .

[0044] like Figure 3As shown, the limit assembly 12 also includes a supporting beam 122, a guide column 123 and two pull rod structures 125, wherein the supporting beam 122 is mounted at the lower end of the inclined track 11, and the two ends of the supporting beam 122 are respectively connected to the two track side edges 111, and an avoidance hole is opened on the supporting beam 122, and the avoidance hole is extended along the inclined direction of the inclined track 11; the guide column 123 is slidably arranged in the avoidance hole, and a counterweight block 124 is provided at the first end of the guide column 123 at the high end of the inclined track 11; the first ends of the two pull rod structures 125 are pivotally connected to the second ends of the guide column 123 at the lower end of the baffle structure 121, and the second ends of the two pull rod structures 125 are respectively connected to the two baffle structures 121. The limiting assembly 12 also includes a first bearing structure 126, which protrudes on a side surface of the supporting beam 122 at the high end toward the inclined track 11, and is located at a position where the supporting beam 122 has an avoidance hole, so that the first bearing hole of the first bearing structure 126 is connected to the avoidance hole, and the guide column 123 is arranged to pass through the first bearing hole and the avoidance hole. In this way, under the action of the counterweight 124, the guide column 123 slides along the lower end direction of the inclined track 11 until the counterweight 124 contacts the first bearing structure 126, thereby preventing the guide column 123 from continuing to slide downward. In addition, under the coordinated action of the two pull rod structures 125, the two baffle structures 121 swing relatively close to each other around the pivot connections with the two track sides 111, forming a pair of clamps. At this time, the distance between the lower ends of the two baffle structures 121 is the smallest and is smaller than the diameter of the barrel cover 100. Of course, when the two baffle structures 121 are in the expanded state, the distance between the lower ends of the two baffle structures 121 is the largest and is larger than the diameter of the barrel cover 100, ensuring that the barrel cover 100 can move with the barrel-shaped container 200.

[0045] It should be noted that, in the present application, the extension direction of the guide post 123 is consistent with the inclination direction of the inclined track 11. In this way, the extension direction of the guide post 123 and the inclination direction of the inclined track 11 can be parallel to each other, ensuring that the guide post 123 can move along the inclination direction of the inclined track 11, while ensuring the smooth movement of the guide post 123.

[0046] like Figure 3 As shown, the two baffle structures 121 are perpendicular to the plane where the inclined track 11 is located. In this way, it is ensured that the two baffle structures 121 can form a clamping effect as much as possible to limit the barrel cover 100.

[0047] Further, the second ends of the two tie rod structures 125 are respectively connected to the edge of one side of the two baffle structures 121 away from the bucket cover 100. In this way, it is helpful to prevent the two tie rod structures 125 from forming obstacles to the movement of the bucket cover 100.

[0048] Of course, from Figure 3 It can also be seen that the connection position between the second end of the pull rod structure 125 and the baffle structure 121 is located between the lower end of the baffle structure 121 and the pivot connection between the baffle structure 121 and the track side 111.

[0049] Optionally, the first bearing structure 126 is a linear bearing.

[0050] like Figure 1 and Figure 3 As shown, the upper cover device further includes a track support frame 30 and a slide plate structure 40, the track support frame 30 has a support hole 31, and the inclined track 11 is penetrated at the support hole 31; the first end of the slide plate structure 40 is connected to the track support frame 30, and the second end of the slide plate structure 40 is connected to the support beam 122 or the track side 111; wherein, the slide plate structure 40 is extended along the extension direction of the inclined track 11, and is arranged at a distance from the track bottom surface of the inclined track 11 for supporting the barrel cover 100, so that a limiting channel for the barrel cover 100 to slide down is formed between a part of the track bottom surface of the inclined track 11 and the surface of the slide plate structure 40 facing the track bottom surface. In this way, the track support frame 30 plays a supporting role for the inclined track 11, and at the same time, the setting of the slide plate structure 40 plays a limiting and guiding role for the barrel cover 100, ensuring that the barrel cover 100 can move smoothly and steadily along the extension direction of the inclined track 11.

[0051] like Figure 1 and Figure 3 As shown, there are two slideway pressure plate structures 40, which are arranged at intervals and are respectively close to the track side 111 on the same side. In this way, the two slideway pressure plate structures 40 are guaranteed to guide and limit the barrel cover 100 with reliability.

[0052] like Figure 1 and Figure 3As shown, the upper cover device also includes a cover pressing assembly 50, which is located downstream of the cover hanging and unloading mechanism 10. The cover pressing assembly 50 includes a support structure 51, a second bearing structure 52, a force guide rod 53 and a spring structure 55, wherein the support structure 51 has an inclined portion 511 and a horizontal portion 512 connected to each other, wherein the inclined portion 511 is connected to the supporting crossbeam 122, and the horizontal portion 512 has a mounting plate section 5121, and an assembly hole is opened on the mounting plate section 5121; the second bearing structure 52 is arranged on the mounting plate section 5121 facing upward On one side surface of the barrel 100, and located at the position where the mounting plate section 5121 has an assembly hole, so that the second bearing hole of the second bearing structure 52 is connected to the assembly hole; the force guide rod 53 can slide through the assembly hole and the second bearing hole and is connected to the pressure plate structure 54; the spring structure 55 is sleeved on the outer peripheral side of the force guide rod 53 located between the mounting plate section 5121 and the pressure plate structure 54, so that the two ends of the spring structure 55 are respectively in contact with the mounting plate section 5121 and the pressure plate structure 54, so as to provide the pressure plate structure 54 with elastic force to press the barrel cover 100 downward. In this way, by setting the pressure cover assembly 50, the purpose of initially pressing the barrel cover 100 on the barrel-shaped container 200 is achieved. At the same time, the barrel cover sets the pressure cover assembly 50 into a structural form including the support structure 51, the second bearing structure 52, the force guide rod 53 and the spring structure 55, and the spring structure 55 provides the pressure plate structure 54 with elastic force to press the barrel cover 100 downward, thereby ensuring the reliability of the pressure plate structure 54 pressing the barrel cover 100.

[0053] Optionally, the second bearing structure 52 is a linear bearing.

[0054] like Figure 3 As shown, there are two force guide rods 53, which are arranged at intervals along the moving direction of the barrel-shaped container 200, there are two assembly holes, which correspond to the two force guide rods 53 one by one, and there are two second bearing structures 52, which correspond to the two force guide rods 53 one by one. In this way, it is ensured that the two spring structures 55 respectively arranged on the two force guide rods 53 can simultaneously provide the elastic force for the pressure plate structure 54 to press the barrel cover 100 downward, thereby ensuring that the pressure plate structure 54 can apply a stable pressing force to the barrel cover 100, ensuring the force balance of the barrel cover 100, and preventing the barrel cover 100 from tilting.

[0055] It should be noted that in an embodiment not shown in the figure of the present application, the gland assembly 50 further includes a limit pin, and a limit hole is provided at the end of the force guide rod 53 outside the second bearing hole, and the limit hole extends along the radial direction of the force guide rod 53, and the limit pin is inserted into the limit hole. In this way, the setting of the limit pin plays a role in limiting the force guide rod 53, preventing the force guide rod 53 from coming out of the assembly hole and the second bearing hole.

[0056] It should be noted that the above-mentioned cover placing mechanism 20 is a prior art and will not be described in detail here.

[0057] It should be noted that the upper cover device in the present application also includes a cover storage portion, which has a cover storage space and a cover outlet connected to the cover storage space; the cover placement mechanism 20 is located between the cover storage portion and the high end of the inclined track, and the cover outlet is arranged toward the suction cup fixture of the cover placement mechanism 20.

[0058] Through the above arrangement, the suction cup fixture of the lid placing mechanism 20 can be used to absorb the lid of the lid opening, and the lid can be rotated 180° and moved to the high end of the inclined track. The lid slides from the inclined track to the barrel mouth, and is hung on one side of the lid by the edge of the barrel and taken away, and placed flat on the barrel mouth.

[0059] Specifically, the cover storage part includes a support base and a plurality of columns. The support base is arranged on the frame, and a through hole is provided on the support base, and the through hole forms a cover outlet; a plurality of columns are arranged on the support base, and the plurality of columns are arranged at intervals around the axis of the through hole to enclose a cover storage space. Through the above arrangement, the cover storage space enclosed by the plurality of columns can store a plurality of spare covers, so that a plurality of barrel covers can be placed above the high end of the inclined track at one time, so that multiple handling can be avoided to realize automation, thereby improving the assembly efficiency of the barrel cover and the barrel. The height of the space enclosed by the columns is the height of the space for storing the barrel cover.

[0060] Furthermore, the storage cover portion also includes at least two clamping members evenly spaced along the circumference of the storage cover space, the clamping member having a fixed end and a telescopic end movably arranged relative to the fixed end, and the telescopic end is arranged toward the storage cover space.

[0061] It should be noted that the telescopic ends of at least two clamps can clamp the lid above the lid outlet, thereby preventing the barrel lid from falling out of the lid storage space unnecessarily during the assembly process of the lid and the barrel. At least two clamps are arranged relative to each other on a horizontal plane. The clamp includes a cylinder and a splint on the cylinder rod of the cylinder, the cylinder is used to form a fixed end, the splint is used to form a telescopic end, and the cylinder rods of all cylinders point to the center of the lid storage space. When the suction cup jig does not take the lid from here, the cylinder rod of the cylinder extends, and the splint clamps and stabilizes the lid; when the suction cup jig takes the lid from here, the cylinder rod of the cylinder is retracted, the splint releases the lid, and when the lid moves downward as a whole by the thickness of a lid, the cylinder rod of the cylinder extends again, the splint clamps and stabilizes the lid, and the suction cup jig can take the bottom lid away for use.

In this way, it is ensured that the sliding plate 64 is slidably connected with the lifting plate 63 through the cooperation of the slider 641 and the guide rail 631, and at the same time, the reliability of the lifting and lowering driving of the sealing jaw structure 62 by the first driving unit 65 is ensured.

[0064] like Figure 1 and Figure 7 As shown, the accompanying capping mechanism 60 further includes a second driving unit 66, which is disposed on the lifting plate 63, and a second driving shaft of the second driving unit 66 extends in the horizontal direction and is drivingly connected to the sliding plate 64. In this way, the driving reliability of the sliding plate 64 by the second driving unit 66 is ensured, thereby ensuring the movement reliability of the sliding plate 64.

[0065] Optionally, the outer peripheral side of the second drive shaft has a first external thread structure, and the sliding plate 64 is provided with an assembly block, which has a first internal thread structure for cooperating with the first external thread structure, so as to adjust the moving direction of the sliding plate 64 by changing the rotation direction of the second drive shaft. In this way, the moving direction of the sliding plate 64 is conveniently adjusted.

[0066] like Figure 1, Figure 2 , Figures 4 to 7 As shown, the accompanying capping mechanism 60 further includes a third driving part 67, which is arranged on the supporting frame 61 and has a third driving shaft, which is drivingly connected to the input shaft of the reducer 68, and the output shaft of the reducer 68 extends in the vertical direction and is drivingly connected to the lifting plate 63; wherein, the outer peripheral side of the output shaft has a second external thread structure, and the lifting plate 63 has a second internal thread structure for cooperating with the second external thread structure, so as to adjust the lifting plate 63 to rise or fall by changing the rotation direction of the output shaft. In this way, the convenience of adjusting the rise and fall of the lifting plate 63 is ensured.

[0067] like Figure 1 , Figure 2 , Figures 4 to 7 As shown, the accompanying capping mechanism 60 also includes a transition support frame 69 and a follow-up capping blocking frame 610, and the transition support frame 69 is arranged on the surface of the sliding plate 64 away from the lifting plate 63; the follow-up capping blocking frame 610 is connected to the surface of the transition support frame 69 away from the sliding plate 64, and the end of the follow-up capping blocking frame 610 away from the transition support frame 69 is in an open state, and the opening is used to avoid the barrel-shaped container 200, and the sealing clamp structure 62 is located in the limited space surrounded by the follow-up capping blocking frame 610; wherein, the follow-up capping blocking frame 610 is provided with a fourth driving part 620 on the two side frames in the direction perpendicular to the moving direction of the barrel-shaped container 200, and the two fourth driving parts 620 are arranged opposite to each other, and the driving end of each fourth driving part 620 is connected to the follow-up capping clamp 630, and the two follow-up capping clamps 630 can move toward each other and move away from each other synchronously. In this way, it is ensured that the two follow-up capping clamping blocks 630 can clamp the side wall surface of the barrel-shaped container 200 , so that the barrel-shaped container 200 can be located directly below the sealing jaw structure 62 .

[0068] The accompanying capping mechanism 60 is installed above the conveying mechanism 300. The accompanying capping mechanism 60 includes a supporting frame 61. A plurality of vertical supporting guide columns 611 are arranged in the frame of the supporting frame 61. A horizontal lifting plate 63 is arranged between the supporting guide columns 611. The lifting plate 63 can move up and down along the axial direction of the supporting guide columns 611. A third driving part 67 and a reducer 68 are fixedly arranged on the top of the supporting frame 61. The third driving part 67 drives the reducer 68 to work. The output shaft of the reducer 68 is vertically downward. A screw is arranged on the output shaft of the reducer 68. The screw is connected to the lifting plate 63 through a threaded pair, and the lifting plate 63 is driven to rise or fall through forward and reverse rotation.

[0069] A set of guide rails 631 are arranged on the plate surface of the lifting plate 63, and the axial direction of the guide rails 631 is the same as the direction of the conveying mechanism 300. A slider 641 is arranged on the guide rail 631, and a sliding plate 64 is fixedly arranged on the lower surface of the slider 641. A second driving part 66 is also arranged on the lifting plate 63, and a horizontal screw rod is arranged on the motor shaft of the second driving part 66. The horizontal screw rod is connected to the sliding plate 64 through a threaded pair, and the sliding plate 64 is driven to move left and right along the guide rails 631 by forward and reverse rotation.

[0070] A vertically arranged first driving part 65 is arranged on the sliding plate 64 , and a sealing clamp structure 62 is installed at the end of the cylinder rod of the first driving part 65 . The sealing clamp structure 62 is a prior art and will not be described in detail here.

[0071] Further optimization, the sliding plate 64 is also fixedly connected with a follow-up capping blocking frame 610, the cross section of which is a C-shaped opening facing downward, the left and right sides of the follow-up capping blocking frame 610 are open sides, the front and rear sides of the follow-up capping blocking frame 610 are frames, and a pair of opposite fourth driving parts 620 are arranged on the front and rear frame shears, and the ends of the fourth driving parts 620 are arranged as follow-up capping clamps 630. When the barrel-shaped container 200 follows the conveying mechanism 300 to reach the inlet end of the support frame 61, the cylinder rods of the fourth driving part 620 extend relatively, and the two follow-up capping clamps 630 clamp the side walls of the barrel-shaped container 200, and this action mainly makes the barrel-shaped container 200 located directly below the sealing clamp structure 62. At the same time, the lifting plate 63 moves downward under the drive of the third driving part 67, so that the sealing jaw structure 62 contacts the barrel cover 100 on the top of the barrel container 200, and then the first driving part 65 drives the sealing jaw structure 62 to work, and seals the barrel cover 100 on the barrel mouth of the barrel container 200. This sealing step requires a process, during which the barrel container 200 moves along with the conveying mechanism 300, so the sliding plate 64 on the lifting plate 63 moves at the same speed as the barrel container 200 under the drive of the second driving part 66, thereby ensuring that the sealing jaw structure 62 on the sliding plate 64 and the barrel container 200 are relatively stationary.

[0072] When using this device:

[0073] When the barrel cover 100 slides to the bottom of the inclined track 11, the lower side edges of the barrel cover 100 respectively collide with the lowermost ends of the two baffle structures 121, and the front edge of the barrel-shaped container 200 hangs the lowermost part of the barrel cover 100. Under the traction of the barrel-shaped container 200, the barrel cover 100 is dragged forward with the barrel-shaped container 200, and the side edges of the barrel cover 100 respectively squeeze the lowermost ends of the baffle structures 121. When the pulling force of the barrel-shaped container 200 on the barrel cover 100 is greater than the force of the counterweight block 124 on the baffle structure 121, the two baffle structures 121 are relatively separated and swung around the corresponding rotation axes until the distance between the two baffle structures 121 is the largest. The contact between the barrel cover 100 and the two baffle structures 121 is released, and the distance between the two baffle structures 121 becomes the smallest again under the drive of the counterweight block 124, so as to carry out the next cover dropping process. When the barrel cover 100 on the barrel passes under the capping assembly 50, the lower plate surface of the auxiliary pressing plate 3-4 presses the barrel cover 100 so that the barrel cover 100 is correctly positioned on the barrel.

[0074] When the barrel follows the conveying mechanism 300 to reach the inlet end of the support frame 61, the cylinder rod of the fourth driving part 620 extends relatively, and the two follow-up capping clamps 630 clamp the side wall of the barrel. This action mainly makes the barrel be located directly below the sealing clamp structure 62. At the same time, the lifting plate 63 moves downward under the drive of the third driving part 67, so that the sealing clamp structure 62 contacts the barrel cover on the top of the barrel, and then the first driving part 65 drives the sealing clamp structure 62 to work and seal the barrel cover on the barrel mouth. This sealing step requires a process. During this process, the barrel moves along with the conveying mechanism 300, so the sliding plate 64 on the lifting plate 63 moves at the same speed as the barrel under the drive of the second driving part 66, thereby ensuring that the sealing clamp structure 62 on the sliding plate 64 and the barrel are relatively still.
