Description

Technical Field

[0001] The invention relates to the field of filling, and in particular to a linear filling device. Background Art

[0002] In the linear filling technology, the container moves forward in a step-by-step manner on a linear conveying path, and there are multiple work stations distributed on the linear conveying path, such as bottle feeding station, dust removal station, sterilization station, drying station, filling station, sealing station, bottle discharging station, etc. When the container passes through each station one by one, it finally presents an independently packaged unit in the state of containing materials and sealing.

[0003] The existing linear filling equipment is equipped with a bottle supply component, a linear conveying component, and a cap supply component. The bottle supply component adopts a bottle supply structure that sorts bottles in a rotating manner and outputs them one by one. This rotary bottle sorting technology can only correspond to a single type of bottle. The linear conveying component is provided with templates for conveying bottles. Every two templates form a group. A group of templates serves a group of bottles arranged at intervals. Since the template spacing is not adjustable, the linear conveying component can only correspond to a single type of bottle. The cap supply component also adopts a cap supply structure that sorts caps in a rotating manner and outputs them one by one. This rotary cap sorting technology can only correspond to a single type of cap. Therefore, when the linear filling equipment corresponds to a type of bottle and cap, the linear filling equipment is only suitable for this type of bottle and cap. If other types of bottles are to be filled or other types of caps are to be processed, multiple structures on the entire linear filling equipment need to be replaced or adjusted. At this time, the time required for the linear filling equipment to be shut down for rectification is very long, generally requiring dozens of working days. After the rectification, a long debugging phase is required to ensure that the entire machine can operate normally. Therefore, in the prior art, linear filling equipment needs to spend a long time on modification operations when filling bottles of different models, making this type of linear filling equipment unable to quickly be compatible with linear filling operations of multiple bottle types. Summary of the invention

[0014] In the above-mentioned linear filling device, the two groups of bottle-taking robots are both located at the ends of the flexible transport component and are symmetrically distributed along the axis of the conveying direction of the flexible transport component.

[0015] In the above-mentioned linear filling device, the second guide rail mechanism includes a second magnetic guide rail and a plurality of second movers independently slidably disposed on the second magnetic guide rail, and a second clamping arm is fixed to each of the second movers.

[0016] In the above-mentioned linear filling device, adjacent cover clamp assemblies are arranged independently of each other.

[0017] In the above-mentioned linear filling device, all the cover clamp assemblies are arranged in a straight line on the second guide rail mechanism, and adjacent cover clamp assemblies share a second clamp arm.

[0018] In the above-mentioned linear filling device, an airbag clamping assembly is also provided downstream of the flexible cap supply assembly, and the airbag clamping assembly includes a first airbag and a second airbag arranged corresponding to each bottle, and the first airbag and the second airbag are respectively arranged on both sides of the bottle, and a cap screwing assembly is provided above the airbag clamping assembly.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] By setting up a flexible transport component, a flexible bottle supply component and a flexible cap supply component, the problem that the current linear filling device needs a long debugging time after changing the bottle model is solved. Since the flexible bottle supply component adopts a bottle manipulator, it can easily identify and grab the bottle, and the first clamping arm of the bottle clamping mechanism can slide on the first guide mechanism to facilitate the adjustment of the spacing between adjacent first clamping arms, so it can freely adapt to bottles of different models. The flexible transport component can also adjust the initial position difference through the first conveyor belt and the second conveyor belt, and then adjust the spacing between all front clamping plates and rear clamping plates at the same time to adapt to bottles of different models. The flexible cap supply component includes a plurality of independently set second clamping arms, and the second clamping arms can slide on the second guide mechanism, so as to facilitate the adjustment of the spacing between adjacent second clamping arms and adapt to bottle caps of different sizes. The linear filling device with the above structure can conveniently adjust the clamping size of the bottle clamping component, the cap clamping component and the clamping plate to adapt to bottles and bottle caps of different specifications, and shorten the adjustment time after changing the bottle and bottle cap model.

[0021] Furthermore, the first guide rail mechanism includes a first magnetic guide rail and a plurality of first movers independently slidably disposed on the first magnetic guide rail, and a first clamping arm is fixed on each of the first movers. Through the cooperation between the first magnetic guide rail and the first mover, the position of the first mover on the first magnetic guide rail is quickly adjusted by utilizing the change of the magnetic pole, thereby realizing the rapid adjustment of the positions of adjacent first clamping arms, and combining into bottle clamp assemblies of different sizes.

[0022] Furthermore, the adjacent bottle clamp assemblies are independently arranged, which makes the control simpler, and the movement of a designated bottle clamp assembly will not affect the adjacent bottle clamps, and the bottle clamp assembly clamping the bottle can be moved to a designated position to prepare for the next process.

[0023] Furthermore, all the bottle clamp assemblies are arranged in a straight line on the first guide rail mechanism, and adjacent bottle clamp assemblies share a first clamp arm, thereby reducing the number of first clamp arms, lowering production costs, and making the structure of the entire flexible bottle supply assembly more compact.

[0024] Furthermore, there are two groups of bottle picking manipulators, and a bottle placing area is provided between the two groups of bottle picking manipulators, and the first guide rail mechanism extends to the area covered by the two groups of bottle picking manipulators. When one group of bottle picking manipulators clamps bottles, the bottle clamping assembly of the other group that has clamped bottles can dock with the flexible transport assembly to transfer bottles, thereby improving the efficiency of conveying bottles to the flexible transport assembly, and the bottle clamping assemblies corresponding to the two groups of bottle picking manipulators can share a magnetic guide rail, which is conducive to reducing the overall cost and making the entire device structure more compact.

[0025] Furthermore, the two groups of bottle picking manipulators are both located at the ends of the flexible transport assembly and are symmetrically distributed along the axis of the flexible transport assembly in the conveying direction. After the two symmetrically distributed groups of bottle picking manipulators clamp the bottles, the bottle clamping assemblies move to the transport position at the same distance, making it easier to control the time for the two bottle picking manipulators to clamp the bottles.

[0026] Furthermore, the second guide rail mechanism includes a second magnetic guide rail and a plurality of second movers independently slidably disposed on the second magnetic guide rail, and a second clamping arm is fixed on each of the second movers. Each second clamping arm corresponds to a second mover, so that the positions of adjacent second clamping arms are easier to control, and the clamping cover assembly can be easily adjusted to fit the bottle cap by adjusting the position of the second mover on the second magnetic guide rail.

[0027] Furthermore, the adjacent cap clamping assemblies are independently arranged to simplify the control logic of the cap clamping assemblies, and when a group of cap clamping assemblies receives the bottle caps delivered by the cap clamping robot, they can move to a designated position to wait for the next process without being affected by other cap clamping assemblies.

[0028] Furthermore, all cover clamp assemblies are arranged in a straight line on the second guide rail mechanism, and adjacent cover clamp assemblies share a second clamp arm, thereby reducing the number of second clamp arms, lowering production costs, and making the structure of the entire flexible cover supply assembly more compact.

[0029] Furthermore, an airbag clamping assembly is provided downstream of the flexible cap supply assembly, and the airbag clamping assembly includes a first airbag and a second airbag corresponding to each bottle, and the first airbag and the second airbag are respectively provided on both sides of the bottle, and a cap screwing assembly is provided above the airbag clamping assembly. The airbag clamping bottle can automatically adapt to bottles of different models, and after the airbag clamping assembly is used to clamp the bottle, the bottle will not rotate when the cap screwing assembly tightens the bottle cap, so that the bottle cap can be screwed in place.

[0041] A linear filling device comprises a flexible transport component 100, a flexible bottle supply component 200 located upstream of the flexible transport component, and a flexible cap supply component 300 located at the side of the flexible transport component 100;

[0042] The flexible bottle supply assembly 200 includes a bottle picking robot 210 and a bottle clamping mechanism 220, wherein the bottle clamping mechanism 220 includes a first guide rail mechanism and a plurality of first clamping arms 221 independently slidably disposed on the first guide rail mechanism, and every two first clamping arms 221 form a bottle clamping assembly for clamping the bottle 500 delivered by the bottle picking robot 210;

[0043] The flexible transport assembly 100 includes a plurality of groups of clamps, each group of the clamps includes a front clamp 110 and a rear clamp 120, all the front clamps 110 are arranged on the first conveyor belt, and all the rear clamps 120 are arranged on the second conveyor belt, and the distance between the front clamp 110 and the rear clamp 120 is adjusted by adjusting the initial position difference between the first conveyor belt and the second conveyor belt;

[0044] The flexible cap supply assembly 300 includes a cap manipulator 310 and a cap clamping mechanism, wherein the cap clamping mechanism includes a second guide rail mechanism and a plurality of second clamping arms 321 slidably arranged on the second guide rail mechanism, wherein the second guide rail mechanism extends from the coverage area of ​​the cap manipulator 310 to above the flexible transport assembly 100, and every two of the second clamping arms 321 form a cap clamping assembly 320 for clamping the bottle cap 600 transferred by the cap manipulator 310.

[0045] By setting up the flexible transport assembly 100, the flexible bottle supply assembly 200 and the flexible cap supply assembly 300, the problem that the current linear filling device needs a long debugging time after changing the model of the bottle 500 is solved. Since the flexible bottle supply assembly 200 adopts the bottle manipulator 210, it can easily identify and grab the bottle 500, and the bottle clamping mechanism 220 includes a first guide rail mechanism and a plurality of first clamping arms 221 independently slidably arranged on the first guide rail mechanism, and every two first clamping arms 221 form a bottle clamping assembly for clamping the bottle 500 transferred by the bottle taking manipulator 210, so that the first clamping arms 221 can slide on the first guide rail mechanism to facilitate the adjustment of the spacing between adjacent first clamping arms 221, so that different models of bottles 500 can be freely adapted. The flexible transport assembly 100 can also adjust the initial position difference through the first conveyor belt and the second conveyor belt, and then adjust the spacing between each group of front clamping plates 110 and rear clamping plates 120, so as to adapt to different models of bottles 500.

[0050] See also Figures 1 to 4 This is an embodiment of a linear filling device of the present invention. The linear filling device includes a flexible bottle supply assembly 200, a flexible transport assembly 100, and a flexible cap supply assembly 300 in sequence according to the running direction of the bottle 500. The flexible bottle supply assembly 200 is mainly used to arrange the bottles 500 provided by the upstream in a set manner, so as to facilitate batch placement on the flexible transport assembly 100. The flexible transport assembly 100 is mainly responsible for transportation, transporting the bottles 500 arranged by the flexible bottle supply assembly 200 to the downstream, or performing dust removal, sterilization, drying, filling and other operations on the flexible transport assembly 100. The flexible cap supply assembly 300 provides the filled bottle 500 with a bottle cap 600 that seals the bottle mouth, so that the subsequent cap screwing device can screw the bottle cap 600 on the bottle 500. The sizes of bottles 500 and bottle caps 600 may vary for different products. In order to handle and transport bottles 500 and bottle caps 600 during the filling process, it is necessary to be able to quickly adapt to bottles 500 and bottle caps 600 of different specifications. Therefore, the present invention will adopt a flexible design in supply and transportation, which can quickly adapt to products of different models.

[0051] The flexible bottle supply assembly 200 includes a bottle picking robot 210 and a bottle clamping mechanism 220. The bottle picking robot 210 is used to clamp the bottle 500 provided by the upstream and place it in the correct position. In this embodiment, the solution described in application No. 201510413229.2 can be adopted, using an image recognition device to identify the position of the bottle 500, and then accurately grasping the bottle 500 through a grasping device, and adjusting the bottle 500 to a preset position so that it can be clamped by the bottle clamping mechanism 220.

[0052] The bottle clamping mechanism 220 includes a first guide rail mechanism and a plurality of first clamping arms 221 independently slidably arranged on the first guide rail mechanism. Every two first clamping arms 221 form a bottle clamping assembly for clamping the bottle 500 adjusted to a preset position. The first guide rail mechanism mainly provides support and limits the movement trajectory of the first clamping arms 221. Each first clamping arm 221 is slidably arranged on the first guide rail mechanism. The spacing between adjacent first clamping arms 221 can be freely adjusted to adapt to bottles 500 of different sizes. The bottle 500 can be clamped by controlling the two adjacent first clamping arms 221 to be close. Multiple bottle clamping assemblies cooperate to complete the arrangement of a group of bottles 500, so that the robot can grab the arranged bottles 500 and place them on the flexible transport assembly 100.

[0053] Furthermore, in order to more accurately control the position of each first clamping arm 221, the first guide rail mechanism includes a first magnetic guide rail 222 and a plurality of first movers 223 independently slidably disposed on the first magnetic guide rail 222, and a first clamping arm 221 is fixed on each first mover 223. By using the first magnetic guide rail 222 and the matching first mover 223, the magnetic poles at different positions on the first magnetic guide rail 222 can be controlled by changing the direction of the current, so that the first mover 223 can accurately move to the specified position on the first magnetic guide rail 222, thereby achieving the purpose of accurately clamping the bottle 500. Of course, the magnetic suspension guide rail structure of the existing public structure can also be used to achieve the above purpose.

[0054] In the above embodiment, adjacent bottle clamp assemblies are independently arranged, and each group of bottle clamp assemblies can move to a designated position to cooperate with the bottle picking robot 210. After clamping the bottle delivered by the bottle picking robot 210, the bottle clamp assembly can move to a designated position to prepare for the next procedure without being affected by other bottle clamp assemblies, which makes the control procedure simpler. In addition, in order to make the entire bottle clamp assembly more compact, adjacent bottle clamp assemblies share a first clamp arm 221. For example, if four bottles 500 are to be clamped, there are five first clamp arms 221 in total, which can simplify the structure of the bottle clamp assembly and reduce the overall cost. In addition to the above structure, the bottle clamping mechanism can also use an existing magnetic suspension clamping box device.

[0055] Furthermore, in this embodiment, there are two groups of bottle picking manipulators 210, and a bottle placing area 230 is provided between the two groups of bottle picking manipulators 210. Bottles 500 transported from upstream all enter the bottle placing area 230, which is convenient for the two groups of bottle picking manipulators 210 to pick up bottles, thereby improving the efficiency of bottle picking. The magnetic guide rail extends into the area covered by the two groups of bottle picking manipulators 210, so that the two groups of bottle picking manipulators 210 can simultaneously cooperate with different bottle clamping assemblies on the first guide rail mechanism to clamp bottles 500. Both groups of bottle picking manipulators 210 are located at the end of the flexible transport assembly 100, so that the flexible transport assembly 100 can be fully utilized, and the two groups of bottle picking manipulators 210 are symmetrically distributed along the axis of the conveying direction of the flexible transport assembly 100, so that the distance moved by the bottle clamping assembly corresponding to each group of bottle picking manipulators 210 to the end of the flexible transport assembly 100 is basically equal, which is convenient for controlling the rhythm of conveying bottles 500 to the flexible transport assembly 100.

[0056] In this embodiment, the flexible transport assembly 100 includes a plurality of groups of clamps. According to the running direction of the flexible transport assembly 100, each group of clamps includes a front clamp 110 and a rear clamp 120. Multiple bottles 500 can be clamped between each group of front clamps 110 and rear clamps 120. All the front clamps 110 are arranged on the first conveyor belt, and all the rear clamps 120 are arranged on the second conveyor belt. In the normal transportation process, the first conveyor belt and the second conveyor belt move synchronously to keep the distance between the front clamp 110 and the rear clamp 120 equal, so that the bottles 500 are always clamped; if the size of the bottle 500 needs to be adjusted, the initial position difference between the first conveyor belt and the second conveyor belt is adjusted, that is, one of the conveyor belts is stationary and the other conveyor belt moves alone, so that the distance between all the front clamps 110 and the rear clamps 120 changes, and the bottles 500 of the new size are adapted, so that the adaptation of the entire transport assembly is convenient and fast. The first conveyor belt and the second conveyor belt can be a chain or a belt structure that can be bent, and the first conveyor belt and the second conveyor belt are respectively controlled by corresponding servo motors to move. You can also refer to the existing circulating conveyor device that can achieve the above purpose.

[0057] In this embodiment, the flexible cap supply assembly 300 is used to put a cap on the bottle 500 that has been filled, so that the subsequent cap screwing assembly can screw the cap on the bottle 500. The structure of the flexible cap supply assembly 300 is similar to that of the flexible bottle supply assembly 200. The flexible cap supply assembly 300 includes a cap manipulator 310 and a cap clamping mechanism. The cap manipulator 310 is used to identify and clamp the cap from the cap placement area, adjust the cap to a set angle and transfer it to the cap clamping mechanism. The cap clamping mechanism then transports the cap transferred by the cap manipulator 310 to the bottle 500 at a specified position on the flexible transport assembly 100.

[0058] The cover clamping mechanism includes a second guide rail mechanism and multiple groups of cover clamping assemblies 320. The number of cover clamping assemblies 320 can be equal to the number of bottles 500 between a group of front overtime and rear clamping plates 120. Each group of cover clamping assemblies 320 includes two second clamping arms 321. The two second clamping arms 321 are independently slidably set on the second guide rail mechanism. The second guide rail mechanism extends from the coverage area of ​​the cover manipulator 310 to above the flexible transport assembly 100. By controlling the spacing between the two second clamping arms 321, it is possible to adapt to covers of different sizes, and clamp the cover to transport it from the coverage area of ​​the manipulator to above the flexible transport assembly 100 and place it on the bottle 500 below.

[0059] Furthermore, the second rail mechanism includes a second magnetic rail 322 and a plurality of second movers 323 independently slidably disposed on the second magnetic rail 322, and a second clamping arm 321 is fixed on each second mover 323. Similarly, by utilizing the characteristics of the magnetic rail that the movers are accurately adjusted and react quickly, the spacing between each set of second clamping arms 321 can be accurately controlled to accurately clamp the bottle cap 600 delivered by the cap body manipulator 310, and the movement of the second movers 323 or the spacing between adjacent second movers 323 can be controlled by only changing the program to control the change of the magnetic poles at different positions on the second magnetic rail 322.

[0060] Adjacent cover clamping assemblies are independently arranged. When one group of cover clamping assemblies clamps the bottle caps transferred by the cover body robot 310, it can run to the next process position without considering other cover clamping assemblies, which is simpler in program logic. In addition, the cover body assemblies can be arranged in a line on the second guide rail mechanism, and adjacent cover body assemblies share a second clamping arm 321. To clamp four bottle caps 600, a total of five second clamping arms 321 are needed. The overall number of second clamping arms 321 required will be reduced, and the structure of the cover body assembly will be more compact.

[0061] On the basis of the above embodiment, the flexible cap supply assembly 300 only places the bottle cap 600 on the already filled bottle 500, and a cap screwing assembly is also provided downstream of the flexible cap supply assembly 300, which can screw the bottle cap 600 onto the bottle 500, and the cap screwing assembly can adopt the structure of the existing filling device. However, when the cap screwing assembly tightens the bottle cap 600, the bottle 500 may rotate with the bottle cap 600. Therefore, it is necessary to set an airbag clamping assembly 400 downstream of the flexible cap supply assembly 300. The airbag clamping assembly 400 is located below the cap screwing assembly. The airbag clamping assembly 400 includes a first airbag 410 and a second airbag 420 arranged corresponding to each bottle 500. The first airbag 410 and the second airbag 420 are respectively located on both sides of the bottle 500. The first airbag 410 and the second airbag 420 are inflated to adapt to bottles 500 of various specifications. The bottle 500 is clamped by the airbag, and has a larger contact area with the bottle 500, which can reduce the deformation of the bottle 500 during the clamping process, thereby avoiding liquid extrusion during the deformation of the bottle 500.

[0062] The bottles 500 provided by the upstream can be piled up in the bottle placing area 230 in disorder. The bottle picking robot 210 identifies the position of the bottle 500 according to its own image recognition device, accurately grasps the bottle 500 and adjusts it to a suitable position. After moving to the suitable position, the first mover 223 moves to the suitable position on the first magnetic guide rail 222, and clamps the bottle 500 by two first clamping arms 221. When the bottle picking robot 210 on one side puts four bottles 500 into the corresponding four bottle clamping assemblies, the grabbing robot located at the end of the flexible transport assembly 100 grabs four bottles 500 at one time and moves them above the flexible transport assembly 100. After the bottles 500 fall on the jacking assembly, they are arranged in a straight line and clamped by the front clamping plate 110 and the rear clamping plate 120. Then the front clamping plate 110 and the rear clamping plate 120 descend together with the bottle 500. The front clamping plate 110 is fixedly connected to the first conveyor belt by plugging or clamping, and the rear clamping plate 120 is fixedly connected to the first conveyor belt by plugging or clamping. 120 and the second conveyor belt are also fixedly connected by plugging or snapping, and the bottle 500 moves downstream synchronously with the first conveyor belt and the second conveyor belt. During the movement, the bottle 500 will undergo dust removal, sterilization, drying, filling and other process stations, and then the bottle 500 will reach the cover position. Before the bottle 500 arrives, the cover body robot 310 also relies on the image recognition device to identify the position of the cover, clamp the cover and transfer it to the cover assembly at a set angle. The cover is clamped by the two second clamping arms 321. When all four covers are clamped, the clamping cover assembly moves to the top of the bottle 500 and places the bottle cap 600 on the bottle mouth. The bottle 500 moves downstream to the capping station, and the bottle 500 is lifted up by the lifting mechanism and the bottle 500 is inflated and clamped by the airbag clamping assembly. The capping assembly located above the bottle 500 tightens the cover and the bottle 500, and then the bottle 500 falls and moves to the end of the flexible transport assembly 100 and is removed by the handling robot. In the linear filling device of this embodiment, the bottle picking robot 210 can automatically identify the position of the bottle 500 without the need to specially place the bottle 500. After the bottle picking robot 210 grabs the bottle 500, since the bottle clamp assembly mainly has two independently operated first clamp arms 221 to clamp the bottle 500, the bottle clamp assembly can adapt to a large range of bottle 500 specifications. It is only necessary to adjust the position of the first mover 223 on the first magnetic guide rail 222 to control the bottle clamp assembly to adapt to bottles 500 of different specifications. The adjustment is rapid and the adaptation range is wide. On the flexible transport assembly 100, it is not necessary to adjust the spacing of each group of clamps to adapt to different bottles 500 as in the past. As long as the initial position difference between the first conveyor belt and the second conveyor belt is controlled, the spacing of all front clamps 110 and rear clamps 120 can be conveniently adjusted to adapt to the specifications of the bottle 500. The adjustment method is also simple and rapid. For bottle caps 600 of different specifications, a flexible cap supply assembly 300 is used, and its principle is consistent with that of the flexible bottle supply assembly 200, and the bottle 500 is clamped by two second clamping arms 321 that slide independently.The linear optical mounting device with the above structure can conveniently and quickly adjust the adaptation of multiple key positions for bottles 500 of different models, greatly reducing waiting time and improving production efficiency.
