Description

Technical Field

[0001] The invention relates to the technical field of bottle conveying and filling, in particular to a three-row filling machine and a single-row filling machine based on the three-row filling machine. Background Art

[0002] As a common filling equipment, filling machines are widely used in the filling production of bottles and other containers, and they can ensure the filling quality and filling speed, and meet the various needs of manufacturers and customers.

[0003] Existing filling machines are divided into two types in terms of transmission mode: linear single-row filling machines and rotary filling machines. In terms of filling mode, they are divided into two types: using a plunger pump or other pump body with a set volume for pumping and filling, and using a flow meter or other sensor that combines constant pressure and pipe diameter to monitor the output flow for direct filling. When a flow meter or other sensor that combines constant pressure and pipe diameter to monitor the output flow is used to fill a bottle with a bottle holder, the shape and size of the bottle holder are not easy to form, such as the previous application number of the applicant CN202411563888X, named The setting and effect in a Chinese patent of a lane filling machine, so a single-row filling method is often adopted. When the first group of bottles are filled in the filling area, the second group of bottles are waiting at the entrance of the filling area; when the first group of bottles is filled, the operation of the conveyor line causes the first group of filled bottles to be moved out and the second group of unfilled bottles to enter the filling area for filling. Since each group of filled bottles takes a long time to move out, the filling waiting time of the filling head is long, thereby forming a filling waiting time, reducing the filling efficiency and increasing the production cost of the enterprise.

[0004] To this end, a three-row filling machine and a single-row filling machine based on the three-row filling machine are proposed. On the one hand, under the premise of ensuring the filling quality and improving the filling efficiency, the filling waiting time is shortened, the production cost of the enterprise is reduced and the product footprint is reduced; on the other hand, the filled bottle body can be more conducive to the processing of subsequent processes, avoiding the problem that large batches of materials are needed in the intermediate links to meet the overall production efficiency due to the long filling time and the short time of the processes such as capping and capping; importantly, with the help of the original carrier, the bottle body without the bottle holder can also be filled, which meets the multi-purpose of one machine and saves the cost of the enterprise to purchase additional equipment. Summary of the invention

[0005] The object of the present invention is to provide a three-row filling machine and a single-row filling machine based on the three-row filling machine; by arranging a first channel, a filling table, a second channel, a bottle pushing assembly, a plurality of blocks, a bottle blocking assembly or the cooperation between the block and the bottle blocking assembly, the bottle pushing assembly pushes the bottle holder and the bottle body between two adjacent blocks, between two bottle blocking assemblies or between the block and the bottle blocking assembly in the filling area of ​​the first channel to the filling table for filling, or pushes the bottle holder and the bottle body between two adjacent blocks, between two bottle blocking assemblies or between the block and the bottle blocking assembly in the filling area of ​​the first channel to the filling table for filling, and at the same time pushes the bottle holder and the bottle body filled on the filling table to the second channel for discharging, thereby reducing the original lateral movement distance of the bottle holder for discharging to the longitudinal movement distance, Bottles are fed in while filling is being performed, shortening the original bottle feeding time to reduce the waiting time for filling and improving the overall filling efficiency; and on this basis, a detachable guardrail and a drive assembly for driving the canning head to move forward and backward are added, combined with the bottle blocking assembly installed at the inlet and outlet of the second channel, so that the second channel can complete the filling process of bottles without bottle trays, so that one device can process bottles with bottle trays and bottles without bottle trays separately, and there is no need to purchase equipment separately to complete the filling of bottles without bottle trays. In addition, according to the type and characteristics of the filling material, the first channel and the second channel can be made to adopt different coordination to complete the transportation, which reduces the cost of the enterprise and improves the processing type, processing efficiency and product applicability of the equipment.

[0006] To achieve the above object, the present invention provides the following technical solutions: A three-row filling machine comprises a workbench, a mounting seat and a mounting frame, wherein the workbench is mounted with the mounting seat, the mounting seat is connected with the mounting frame, and further comprises: A first channel and a second channel are arranged in parallel, both of which are arranged on a workbench; A filling station is arranged between the first channel and the second channel, and its two sides are respectively connected with the first channel and the second channel, and the width of the filling station is equal to that of the first channel; A plurality of filling heads arranged in a single row on the mounting frame, which are used to simultaneously fill a plurality of corresponding bottles on the filling table; The stoppers are evenly mounted on the first channel, and two adjacent stoppers at the set positions of the first channel are respectively aligned with the two sides of the filling station to form a match; A bottle pushing assembly is arranged at a side of the outlet of the first channel away from the second channel, and its output end acts on the side of the bottle holder to push the first group of bottles that are limited between two adjacent blocks at a set position on the first channel and are equipped with a bottle holder to the filling station for filling, or, while pushing the next group of bottles that are limited between two adjacent blocks at a set position on the first channel and are equipped with a bottle holder to the filling station for filling, the first group of bottles that have completed filling on the filling station are forced to be pushed to the second channel for discharge.

[0007] In the above scheme, multiple bottles are placed on the bottle holder, and each bottle holder is placed between two adjacent blocks on the first channel. The two adjacent blocks limit the bottle holder and its bottle. The bottle holder and its bottle move toward the set position of the first channel as the first channel moves intermittently and equidistantly. When the bottle holder and its bottle move in front of the bottle pushing assembly, the bottle pushing assembly moves to push the bottle holder and its bottle along the blocks on both sides to the filling station. Since the first channel is as wide as the filling station, the moving distance of the bottle holder pushed by the bottle pushing assembly is equal to the width of the first channel or the filling station. In order to improve the accuracy and stability of the filling of the bottles in the filling station by the filling head, the width of the bottle holder is preferably equal to the width of the first channel or the filling station. During the filling process of the bottle holder and its bottle on the filling station, after the bottle pushing assembly is reset, the first channel moves intermittently and equidistantly to transport the next unfilled bottle and its bottle holder to the first channel. The filling table is aligned with the set position; after the bottle on the filling table is filled, the bottle pushing assembly moves to push the bottle and its bottle holder at the set position to the filling table, and the bottle holder and the bottle body filled on the filling table are forced to be pushed to the second channel and discharged with the intermittent operation of the second channel; after the bottle pushing assembly is reset, the next bottle holder moves to the set position, and the above process is repeated to complete the continuous processing. The intermittent movement of the second channel is to better cooperate with the bottle holder and the bottle body filled on the filling table to be forced to be pushed to the second channel, so as to avoid the second channel being misplaced and dumped due to the continuous conveying, and the bottle holder and the bottle body pushed to the second channel are subjected to thrusts in different directions. The intermittent movement time of the second channel needs to change with the filling time. At this time, since the second channel is intermittent motion, the filling amount in the bottle body cannot be full, otherwise it is easy to overflow due to the inertia force of the intermittent motion; Secondly, since the widths of the preferred bottle holder, the first channel and the filling station are equal, the bottle pushing assembly can move an equal distance to completely push the bottle holder on the first channel to the filling station, avoiding affecting the normal entry of the bottle holder at the set position in the first channel. Of course, the width of the bottle holder may not be equal to the width of the first channel or the filling station. In this case, the width of the bottle holder needs to be smaller than the width of the first channel or the filling station. However, at this time, the position of the bottle holder placed between two adjacent blocks needs to meet the following two requirements: first, all the bottle holders on the first channel are aligned with the sides parallel to the conveying direction of the first channel; second, all the bottle holders on the first channel need to be centered on the first channel; satisfying either or both of these requirements can enable the bottle pushing assembly to move a distance equal to the width of the first channel or the filling station each time, and completely push the bottle holder on the first channel to the filling station; such a setting increases the accuracy of equipment or manual placement of bottle holders, and increases the cost of product manufacturing and use.

[0008] Finally, in order to enable the filling head to fill bottles of different heights, the original mounting base fixed on the workbench is improved so that the original mounting base is replaced by a lifting frame. The filling machine also includes a lifting frame and a lifting assembly, and the lifting assembly is used to drive the lifting frame and multiple filling heads connected to the lifting frame to achieve lifting.

[0009] Preferably, a lifting frame is installed on the workbench, a lifting assembly is installed at one end of the lifting frame, and the other end is connected to a plurality of filling heads arranged in a single row on the mounting frame, the lifting assembly includes a hydraulic cylinder or an air cylinder, and a hydraulic cylinder or an air cylinder is installed at the bottom of the workbench, and the output end of the hydraulic cylinder or the air cylinder is connected to the lifting frame; when the height of the bottle body changes, the pressure of the medium inside the hydraulic cylinder or the air cylinder can be adjusted so that the hydraulic cylinder or the cylinder pushes the lifting frame to complete the movement of the set height. At the same time, for the medium whose filling head needs to be inserted into the bottle body for filling, the lifting assembly also meets the objective practicality of different products.

[0010] It can be seen from the above overall scheme that it relies on the intermittent equidistant movement of the first channel and the limiting constraint and positioning of a bottle holder by two adjacent blocks, so that the conveyor line can set the moving distance each time and complete the intermittent equidistant movement, so that the bottle pushing assembly pushes a bottle holder to the filling station for positioning and filling. When the bottle pushing assembly pushes two bottle holders between three adjacent blocks to the filling station, the gap between the blocks is retained between the two bottle holders pushed to the filling station, and the filling station lacks a mechanism for positioning the two bottle holders, which easily causes the two bottle holders to deviate and shift in the process of being forced to move out of the filling station. It is not easy for it to enter the second channel, so only one bottle holder is pushed at this time; due to the constraint of the bottle holder on the bottle body, the bottle body placed on the bottle holder is not easy to shake and fall off the bottle holder due to intermittent motion; however, for this equipment, the intermittent motion of the first channel can easily reduce the service life of the motor driving the first channel movement, and the start and stop of the intermittent motion will increase the overall conveying accuracy and conveying time. Therefore, the setting and function of the block of this scheme can be replaced by the bottle blocking assembly, so that the first channel can continue to move, and can normally complete the conveying, bottle pushing and processing, thereby improving the overall production efficiency.

[0011] Preferably, the block evenly installed on the first channel can be replaced by two bottle stopper assemblies, which are respectively installed on one side of the entrance area and the exit area at the set position of the first channel, and a guardrail cooperating with the bottle stopper assembly is installed on the other side of the bottle stopper assembly in the entrance area of ​​the first channel. The bottle stopper assembly located in the air outlet area of ​​the set position of the first channel is used to limit the lateral movement of the bottle holder and the bottle body in the set position. The bottle stopper assembly located in the entrance area of ​​the set position of the first channel is used to limit a set number of bottle holders and the bottle bodies thereof from entering the set position in the first channel, and blocking the remaining bottle holders and the bottle bodies on the first channel does not affect the bottle holders and the bottle bodies at the set position.

[0012] In the above scheme, the first channel is in continuous operation. At this time, there is no block on the conveying surface of the first channel, so the bottle holder and the bottle body can be placed on the first channel in sequence for conveying, so that the bottle holder runs with the operation of the first channel. When it runs to the set position of the first channel, it will be blocked by the bottle blocking component in the set position exit area. When the set time or the set number is reached, the bottle blocking component in the set position entrance area moves to block the bottle holder and the bottle body that have not entered the set position or are outside the set position. At this time, the bottle holder and the bottle body that have not entered the set position are constrained by the bottle blocking component and the corresponding guardrail to stop moving to the set position. After that, the bottle pushing component The bottle holders and bottle bodies of the set number in the set position are pushed to the filling station for filling. After the bottle pushing assembly is reset, the bottle blocking assembly in the entrance area of ​​the set position is reset, and the bottle holders and bottle bodies blocked by the bottle blocking assembly and the guardrail move toward the set position. After the next set number of bottle holders enter the set position, the bottle blocking assembly and the guardrail cooperate with each other to block the remaining bottle holders that have not entered the set position. The movement of the bottle pushing assembly pushes the bottle holders and bottle bodies in the set position to the filling station, and the filled bottles and bottle holders on the filling station are forced to move to the second channel, and then are discharged through the intermittent movement of the second channel. Repeat this step to complete the continuous processing; In particular, in the above overall solution, the set position refers to the area on the first channel that is aligned with the filling station, that is, the bottle pushing assembly can push the bottle holder and its bottle holder at the set position in the area to the filling station. At the same time, since there is no block between the two bottle blocking assemblies, the bottle pushing assembly can simultaneously push one or more bottle holders to the filling station for filling, and since the second channel is an intermittent motion, the multiple bottle holders on the filling station are in a state of conflict with each other, so they are not easily misaligned when they are forced to be pushed to the second channel.

[0013] It can be known that, for the bottle blocking assembly defined in the above scheme, the following optimization is made for the bottle blocking assembly so that it can meet the requirements of the above scheme.

[0014] Preferably, the bottle blocking assembly comprises a first cylinder and a first blocking piece, the first cylinder is mounted on a workbench, and the output end of the first cylinder is mounted with a first blocking piece for limiting bottle holders that have not entered a set position in the first channel.

[0015] At the same time, in order to better enable the first baffle to block the bottle holders at different positions and to keep the bottle holders pushed to the filling station in a parallel posture, the first baffle is optimized as follows.

[0016] The first baffle is L-shaped, and includes a supporting section and a limiting section. The first baffle located in the entrance area of ​​the first channel setting position has a supporting section that is against the side of the bottle holder and is parallel to the conveying direction of the first channel, and the first baffle located in the exit area of ​​the first channel setting position has a limiting section that is against the side of the bottle holder along the conveying direction of the first channel and is perpendicular to the conveying direction of the first channel.

[0017] In the above scheme, since the bottle blocking assembly needs to limit and release the limit of the bottle holders inside and outside the set position, its driving parts are preferably driving parts with adjustable stroke or set stroke such as the first cylinder, and the first cylinder drives the first blocking piece to move by the telescopic column, that is, the movable end, of the first cylinder through the inlet and outlet of gas; when a set number of bottle holders enter the first channel, the limiting section of the first blocking piece located in the outlet area of ​​the set position of the first channel remains in an extended state, preventing the bottle holders entering the set position from continuing to move forward; when the bottle holders in the set position reach the set number, the abutting section of the first blocking piece located in the entrance area of ​​the set position of the first channel extends, and then the bottle holders that have not entered the set position of the first channel are stopped by cooperating with the corresponding guardrail. When the bottle pusher pushes the bottle holder at the set position to the filling station, after the bottle pusher is reset, the abutting section of the first baffle at the entrance area of ​​the set position of the first channel is reset, and the blocked bottle holder enters the set position with the continuous movement of the first channel. When the bottle bodies of the filling station are filled and the next group of bottle holders of the set number enter the set position, the abutting section of the first baffle at the entrance area of ​​the set position of the first channel extends out to block the subsequent movement of the bottle holder. At this time, the bottle pusher moves to push the bottle holder and its bottle body at the set position to the filling station, and the filled bottle body and its bottle holder on the filling station are forced to be pushed to the second channel and discharged with the intermittent movement of the second channel. By cyclically operating in this way, the processing requirements can be met and the filling efficiency can be improved. Since the bottle holder supports the bottle body, the bottle body that suddenly stops will not fall over due to inertia. At the same time, during the pushing process of the bottle pushing assembly, the bottle holder located at the set position of the first channel is subjected to the movement of the first channel when being pushed, so that multiple bottle holders are pressed against each other and clamped by the two first blocking sheets to form a guiding effect, so that one or more bottle holders between the two bottle blocking assemblies are smoothly pushed to the filling table, avoiding dislocation or deflection during the pushing process, so that it can better meet the production requirements and filling requirements.

[0018] It can be seen that when the first channel is intermittent and equidistant motion, in order to meet the need for continuous discharge of liquid media after filling and improve the filling accuracy of the bottle on the filling station, the above scheme is combined to make the following optimizations for the installation position of the block, the guiding, positioning, blocking and other functions of the block.

[0019] Preferably, the filling station is also evenly provided with at least two blocks, and the blocks on the filling station correspond one-to-one with the blocks at set positions on the first channel and cooperate with each other.

[0020] In the above scheme, when the first channel adopts intermittent equidistant motion to transport bottle trays and empty bottles, the degree and number of the bottle trays can be set according to the size of the bottle bodies, so that the distance between two adjacent bottle bodies on one bottle tray is equal or the distance between two adjacent bottle bodies on multiple bottle trays is equal, so that the filling head can better align the bottle bodies for filling; since a bottle tray is placed between two adjacent blocks, the limiting or pushing of the bottle tray is not easy to cause the bottle tray to be misaligned, so when the bottle pushing assembly only pushes one bottle tray each time, its filling table needs to be provided with two blocks to correspond to the two blocks at the set positions; when the bottle pushing assembly completes the pushing of two or more bottle trays each time, the filling table needs to be evenly provided with a plurality of blocks with the same number as the blocks at the set positions, for example, if the bottle pushing assembly pushes two bottle trays at a time, there are three adjacent blocks at the set position of the first channel, and three blocks are evenly provided on the filling table The three adjacent blocks at the set position cooperate with each other, so that the two bottle holders between the three adjacent blocks at the first channel setting position are pushed to the filling station along the blocks by the bottle pushing assembly for filling at the same time; and after filling, during the next pushing process of the bottle pushing assembly, the filled bottle body and the bottle holder on the filling station are forced to move out of the filling station along the blocks of the filling station and enter the continuously running second channel for discharging. Since the second channel is continuously running, the setting of the filling station block is necessary, firstly, to position the bottle holder and the bottle body pushed to the filling station so as not to be misplaced, so as to avoid affecting the filling; secondly, in the process of being forced to be pushed out of the filling station, the bottle holder will be discharged with the movement of the second channel only after completely losing the constraints of the blocks on both sides of the filling station, so as to avoid the problem that there are no blocks on both sides of the filling station, the bottle holder is pushed out of the filling station and moves directly after contacting the second channel, causing the bottle holder to be misplaced and fall without limit; The continuous movement of the second channel in the setting of this product is to better discharge the filled bottles and their bottle holders and increase the filling efficiency, so its movement mode is continuous movement; if the movement mode of the second channel is the intermittent movement of the bottle holder in the above scheme in conjunction with the bottle pusher assembly, firstly, when the second channel is used to fill the bottle with liquid, the inertia caused by the intermittent movement may cause the liquid medium inside the bottle to overflow; secondly, it is not conducive to the second channel to transport the transported bottles and their bottle holders to the next process for processing, so when the second channel is in continuous motion, the setting of the filling station block is necessary; It can be seen that when the first channel is in continuous motion, in order to meet the need for continuous discharge of liquid media after filling and to improve the filling accuracy of the bottle on the filling station, the above scheme is combined to make the following optimizations for the installation position of the block, the guiding, positioning, blocking and other functions of the block.

[0021] Preferably, the filling table is also evenly provided with two blocks, the length between the two blocks is equal to the total length of a set number of bottle holders between the abutment section and the limit section at the set position of the first channel, and the block located on the filling table near the outlet area of ​​the first channel is extended to the first channel and can replace the bottle blocking assembly in the outlet area at the set position of the first channel.

[0022] In the above scheme, when the first channel adopts continuous motion to transport the bottle holder and its empty bottle, since the number of the bottle holders between the two bottle blocking assemblies can be one or more, when the number of the bottle holders is multiple, the bottle holders are in a mutually abutting posture. At this time, the movement of the bottle pushing assembly can push the multiple bottle holders to the filling table under the clamping and guidance of the two first blocking pieces, and be limited by the two blocks on the filling table. After the filling is completed, when the bottle holders are forced to be pushed out of the filling table, the filled bottles and their bottle holders on the filling table will be discharged with the movement of the second channel only after completely losing the constraints of the blocks on both sides of the filling table, so as to avoid the problem that there are no blocks on both sides of the filling table, and the bottle holders are pushed out of the filling table and move directly after contacting the second channel, resulting in the problem that the bottle holders are not limited, misaligned, tipped over and fell.

[0023] It can be seen that for the mutual cooperation between the first channel and the filling station, when the first channel is intermittently and equidistantly moved, the block on the first channel and the block on the filling station need to be aligned one by one to form a guiding effect. However, due to the existing technical defects, the first channel, that is, the generalized conveyor line, will accumulate travel errors during movement, resulting in the block at the set position on the first channel and the block on the filling station cannot be completely aligned, which will affect the bottle pusher assembly to push the bottle holder at the set position into the filling station. Therefore, in order to reduce the influence of the travel error on the bottle pusher, one is to use a sensor for alignment so that the block at the set position is aligned with the block of the filling station under the reset of the first channel. However, such a setting increases the difficulty of controlling the first channel and increases the equipment manufacturing cost. Therefore, this scheme adopts the following optimization of the block; Preferably, the widths at both ends of the stopper are smaller than the width in the middle portion, and the widths at both ends increase successively toward the middle portion.

[0024] In combination with the aforementioned scheme, two adjacent blocks on the first channel are used to limit a bottle holder. Since the width of the middle part of the block is greater than the width of the two ends of the block, a guiding inclined surface is formed for the bottle holder to contact when being pushed. It can be seen that when the bottle holder contacts the guiding inclined surface of the block, the corresponding bottle holder can be smoothly guided from the first channel to the filling table, and then stably enter the filling table, avoiding affecting the filling and the filling accuracy of its filling head; when the first channel adopts two bottle blocking assemblies to limit the movement of the bottle holder, the two blocks on the filling table can also better cooperate with the two first blocking pieces, thereby guiding the bottle holder pushed to the filling table.

[0025] It can be seen that there are many mechanisms for pushing the bottle tray in the set position to the filling table. Combining the above scheme and the design concept of this product, the effect formed by the bottle pushing assembly must meet both the high pushing speed and the accurate pushing distance, so that the bottle tray on the first channel can be stably pushed to the fixed position on the filling table for filling, and the filled bottle tray on the filling table and its bottle tray can be pushed to the second channel for smooth discharge.

[0026] Preferably, the bottle pushing assembly includes a second cylinder and a first push plate, the second cylinder is installed on a side away from the first channel of the filling station, the first push plate is installed at the output end of the second cylinder, and the length of the first push plate is less than or equal to the length of the bottle holder between two adjacent blocks.

[0027] In combination with the above-mentioned scheme, no matter whether the first channel adopts the block positioning and intermittent equidistant movement, or the first channel adopts the bottle blocking assembly and continuous movement, its bottle pushing assembly is preferably driven by the second cylinder to drive the first push plate, so that the first push plate obtains a fixed set stroke, and the cylinder drive is compared with the motor driving the first push plate to do the forward and backward pushing action. The cylinder has the advantages of short working time and high efficiency, which is easier to meet actual needs and complete the set distance movement of the bottle holder, so as to improve the matching accuracy between the filling head and the corresponding bottle body, shorten the pushing time, and speed up the overall filling efficiency; when the first push plate is pushing the bottle holder between three or more adjacent blocks, the first push plate must be higher than the height of the block on the first channel to avoid the first push plate from contacting with the block to form interference, but the first push plate still needs to be against the bottle holder, so that it can push the bottle holder and its bottle body to the filling station through contact with the bottle holder.

[0028] Combined with the above overall or partial settings, the second channel of this product can be improved, and the filling machine can also fill bottles without bottle holders. Preferably, a single-row filling machine based on a three-row filling machine comprises a slide rail mounted on a mounting seat, characterized in that it also comprises: Guardrails, which are detachably arranged on both sides of the second passage; A driving assembly connected to the plurality of filling heads, used for simultaneously translating the plurality of filling heads to above the filling table or above the second channel; and the bottle blocking assemblies respectively arranged on both sides of the filling area of ​​the second channel, the bottle blocking assemblies being used for restraining bottles without bottle holders in the filling area of ​​the second channel.

[0029] In this scheme, the improvement is made by utilizing the corresponding settings of the three-row filling machine in the aforementioned scheme, in which removable guardrails are added on both sides of the second channel. The function of the guardrails is to prevent the bottles without bottle holders from being limited and to prevent the bottles from falling out of the second channel; the two newly added bottle blocking assemblies are respectively located at the entrance and exit on the sides of the set filling position of the second channel, and the two bottle blocking assemblies cooperate with each other to complete the rated number of bottles entering the set position of the second channel for filling; the driving mechanism can move the filling head from above the filling area to above the second channel, and the lifting assembly in the aforementioned scheme is combined to make the filling head descend to fill the bottles in the second channel and between the two bottle blocking assemblies.

[0030] It can be seen that, in order to limit the conveying direction of the bottle body and position the filling, the first baffle acting on the second channel is set as follows.

[0031] Preferably, the first baffle located at the entrance of the filling area of ​​the second channel is a stop section parallel to the movement direction of the second channel, and the stop section is used to limit the entry of empty bottles into the filling area of ​​the second channel; the first baffle located at the exit of the filling area of ​​the second channel is a limit section perpendicular to the movement direction of the second channel, and the limit section is used to block the movement of the bottle body in the filling area.

[0032] In the above scheme, the first baffle in the bottle blocking assembly at the entrance of the second channel filling area, i.e., in the bottle feeding direction, is a supporting section, which cooperates with the corresponding guardrail to achieve abutment against the bottle body, forcing the corresponding bottle body to stop moving into the filling area. The principle is consistent with the function of the first baffle and the corresponding guardrail of the bottle blocking assembly at the entrance of the first channel filling area. The first baffle at the outlet of the filling area of ​​the second channel, i.e., in the direction of output of the filled bottles, is a limiting section, which can be inserted and extended into the second channel to limit the bottles in the filling area from continuing to move in the second channel, so that the stopped bottles complete the filling.

[0033] It can be seen that there are many settings for a set number of bottle holders entering the set position of the first channel for pushing bottles or the set position of the third channel for filling, such as combining the movement of the bottle blocking component with the bottle holder or bottle feeding time feedback, or taking manual intervention. However, the use of time feedback or manual intervention will lead to a delay in the feedback time of the bottle blocking component at the set position. Therefore, in order to increase the speed at which the bottle blocking component blocks the remaining bottle holders or bottles after the bottle is fed in, the following settings are adopted.

[0034] Preferably, a counting sensor is also installed on one side of the bottle blocking assembly located at the entrance of the second channel filling area or at the entrance area of ​​the first channel.

[0035] In the above scheme, the counting sensor installed on one side of the bottle blocking assembly at the entrance area of ​​the first channel can be used to monitor the number of bottles entering the set position, which refers to the number of bottle holders entering the set position, and then feedback to the corresponding bottle blocking assembly to push the corresponding first baffle to move and perform blocking; the technical sensor installed on one side of the bottle blocking assembly at the entrance of the second channel can be used to monitor the number of bottles entering the set position, and cooperate with both bottle blocking assemblies to allow a rated number of bottles to enter the second channel and block the remaining empty bottles from staying in front of the entrance to avoid interference with the bottles being filled.

[0036] It can be known that there are many mechanisms for driving multiple filling heads arranged in a single row on the mounting frame to reciprocate above the filling area at the setting position of the filling station or the second channel. Combined with the above-mentioned preferred first channel, filling station and second channel having equal widths, the connecting line connecting the axis of the bottle mouths of all bottles placed on the filling station or the second channel is preferably located at the center of the corresponding filling station or the second channel, so that the filling head can move the same distance, that is, it can be aligned with the bottle mouths of the bottles placed on the filling station or the second channel, so as to improve the filling accuracy and avoid deviation between the filling head and the bottle mouth, which causes filling leakage.

[0037] Preferably, the driving assembly includes a third cylinder, the third cylinder is mounted on a mounting seat, and an output end of the third cylinder is connected to the plurality of filling heads via a mounting frame, and the mounting frame is slidably mounted on a slide rail.

[0038] According to the aforementioned main scheme, a mounting seat is installed on the workbench, and a mounting frame is connected to the mounting seat. When the filling head installed on the mounting frame needs to move back and forth, the driving end of the third cylinder installed on the mounting seat drives the mounting frame to move, and makes the mounting frame slide on the slide rail, so that the multiple filling heads installed on the mounting frame can be supported to perform horizontal movement parallel to the filling table, so as to complete the reciprocation of the multiple filling heads above the filling table or the second channel, and the filling heads are lowered by the lifting assembly to realize high-speed filling of the bottle body without bottle support in the second channel. For small-capacity bottles or media that are not easy to bubble, the distance between the filling head and the bottle mouth is set. At this time, the filling head does not need to be lowered to perform the filling operation.

[0039] Compared with the prior art, the present invention has the following beneficial effects: 1. In the process of filling bottles with bottle holders, the existing linear single-row filling machine is not easy to form the setting and effect as described in the Chinese patent application number CN202411563888X of the applicant, and the flow meter and other sensors do not need the pumping time required by the plunger pump and other pumps, and only need to wait for the output of the filled bottles so that the empty bottles can be filled again. However, the entry of the next group of empty bottles will cause the filling head to wait for filling, thereby wasting time, reducing the filling efficiency, and increasing the production cost of the enterprise. Therefore, the first channel and the second channel are designed. The channel, bottle pushing mechanism and filling table work together to improve filling efficiency and expand production capacity. On the one hand, under the premise of ensuring filling quality and improving filling efficiency, the distance of the original group of bottles with bottle holders along the conveying direction of the conveyor line is shortened to the moving distance in the width direction of the conveyor line, which shortens the discharging and feeding time of a group of bottle holders, reduces the production cost of the enterprise and improves production capacity. On the other hand, the filled bottles can be more conducive to the processing of subsequent processes, avoiding the problem that large quantities of materials need to be piled in the middle links to meet the overall production efficiency due to long filling time and short time for processes such as capping and capping.

[0040] 2. The present invention sets a block or bottle blocking assembly on the first channel, a block on the filling table, a second channel and a bottle pushing assembly. The purpose is to achieve the mutual cooperation between the structures to shorten the moving distance of the original group of bottles with bottle holders along the conveying direction of the conveying line to the moving distance in the width direction of the conveying line, shorten the feeding time to improve the filling efficiency, and realize diversified transportation and processing by adapting to the difference in the operation mode of the first channel and the second channel; wherein, when the block of the first channel cooperates with the block on the filling table, so that the first channel can move intermittently and the second channel can move continuously, at this time, the second channel can be equipped with an intermittent The moving follow-up capping and screwing machine can cap and screw the filled bottles; when the bottle blocking assembly of the first channel cooperates with the filling table, the feeding time can be accelerated to avoid the waiting time of intermittent movement. In addition, the intermittent movement of the second channel at this time can be matched with a capping and screwing machine with a fixed position at the set position of the second channel, and combined with the corresponding bottle blocking assembly, the bottles filled in the second channel can be capped and screwed. In these two examples, the working efficiency of the capping and screwing can match the efficiency of filling, so that the corresponding process of the bottle can be completed without a large amount of stacking in the intermediate link, reducing the floor space of the equipment.

[0041] 3. The second channel with three rows of filling is used to add detachable guardrails on both sides of the second channel, and the filling head is translated through the driving mechanism to complete the filling of bottles without bottle holders, which increases the versatility of the device. By disassembling and assembling the guardrails of the second channel, one device can perform filling effects on bottles with bottle holders and bottles without bottle holders.

Example 1

[0044] Combine the following Figure 1 , a three-row filling machine is described in detail.

[0045] In order to improve the filling efficiency of the product into the bottle, this solution discloses a three-row filling machine, Figure 1The figure shows a first channel 10 and a second channel 20 arranged in parallel, both of which are arranged on a workbench 001, a filling table 30, which is arranged between the first channel 10 and the second channel 20, and its two sides are connected to the first channel 10 and the second channel 20 respectively, that is, there is no guardrail between the first channel 10, the second channel 20 and the filling table 30; the bottle pushing assembly 5 is arranged on one side outside the first channel 10, and a plurality of filling heads 004 are now located above the filling table 30, and the filling heads 004 descend along the Z axis to fill the corresponding bottles 002 of the filling table 30; a row of a plurality of bottles 002 with bottle holders 003 (such as Fig.11 As shown in the figure, a row of multiple bottles 002 with bottle holders 003 are also placed on the second channel 20; when the device is performing filling work, it is necessary to ensure that the bottle holder 003 on the second channel 20 is in a stationary state, and at the same time, it is necessary to ensure that the bottle holder 003 on the first channel 20 is stationary and located on one side of the bottle holder 003 on the second channel 20; Fig. 9 The specific structure of the bottle pushing mechanism 5 is shown, including a second cylinder 51 and a first pushing plate 52 movably connected to the second cylinder 51; the specific working steps are as follows: Figure 2 As shown, the bottle pushing mechanism 5, whose output end acts on the side of the bottle holder 003, pushes the first group of bottles 002 which are limited and stationary in the first channel 10 and installed with the bottle holder 003 horizontally (along the Y-axis direction) to the filling station 30 for filling, or pushes the second group of bottles 002 which are in the first channel 10 and installed with the bottle holder 003 horizontally (along the Y-axis direction) to the filling station 30 for filling, and forces the first group of bottles 002 which have completed filling on the filling station 30 to be horizontally moved to the second channel 20 for discharge.

[0046] As described above, how to introduce the bottle body 002 with the bottle holder 003 in the first channel 10 and in a stationary state into the filling station 30 for filling, and how to introduce the bottle body 002 with the bottle holder 003 in the filling station 30 and in a stationary state into the second channel 20 for discharging, the present solution provides the following embodiments 2, 3, 4, and 5.

Blocks 4 are arranged at equal intervals on the conveyor belt of the first channel 10. The interval between the two blocks 4 is consistent with the length of the filling station 30. A bottle holder 003 can be placed between the two blocks 4. A plurality of bottles 002 arranged in a straight line are placed on the bottle holder 003. When the conveyor belt rotates until the two blocks 4 are flush with both sides of the filling station 30, it stops, and the bottle pushing mechanism works to push the plurality of bottles 002 horizontally to the filling station 30 for filling. Since there are no block pieces 4 on both sides of the filling station 30, when the bottles 002 on the filling station 30 are pushed to the second channel 20 for discharging, it is necessary to ensure that the conveyor belt on the second channel 20 is in a stationary state. After the bottles 002 are pushed horizontally to the second channel 20, the conveyor belt on the second channel 20 can continue to rotate.

[0048] In summary, in this embodiment, the conveyor belts in the first channel and the second channel move intermittently. Example 3

[0050] like Figure 5 As shown, the figure shows the bottle blocking assembly 6 in the entrance area 11, including a first cylinder 61, the output end of the first cylinder 61 is connected to a first blocking piece 62, the first blocking piece 62 adopts a supporting section 622, the first cylinder 61 is started, and the supporting section 622 moves to the right, the supporting section 622 acts on the side of the bottle body 002, and is pressed at the guardrail 8 to limit the movement of the bottle body 002.

[0051] like Figure 6 As shown, the figure shows the bottle blocking assembly 6 in the entrance area 11, including a first cylinder 61, the output end of the first cylinder 61 is connected to a first blocking piece 62, the first blocking piece 62 adopts a limiting section 621, the first cylinder 61 is started, and the limiting section 621 moves to the right, the front of the bottle body 002 is restricted, and the bottle body 002 is prevented from moving out of the first channel 10.

[0052] In summary, in this embodiment, the conveyor belt in the first channel moves continuously, and the conveyor belt in the second channel moves intermittently. Example 4

[0053] As a preferred embodiment of the present invention, Figure 7 1 shows a top view of the first channel, the second channel and the filling station; the difference between this embodiment and embodiment 3 is that both ends of the filling station 30 are provided with blocks 4, while in embodiment 3, both ends of the filling station 30 are not provided with blocks 4; when the conveyor belt of the first channel 10 rotates until the two blocks 4 are flush with the two blocks 4 of the filling station 30, it stops, and the bottle pushing mechanism works to push multiple bottles 002 horizontally to the filling station 30 for filling. Since blocks 4 are provided on both sides of the filling station 30, when the bottles 002 on the filling station 30 are pushed to the second channel 20 for discharge, there is no need to ensure that the conveyor belt on the second channel 20 is in a stationary state.

[0054] In summary, in this embodiment, the conveyor belt in the first channel moves intermittently, and the conveyor belt in the second channel moves continuously. Example 5

[0055] As a preferred embodiment of the present invention, Figure 8 1 shows a top view of the first channel, the second channel, and the filling station; the difference between this embodiment and embodiment 4 is that a bottle blocking assembly 6 is provided at the entrance area 11 of the first channel 10, a bottle blocking assembly 6 is provided on the left side of the first channel 10, and a guardrail 8 is provided on the opposite side of the bottle blocking assembly 6 of the entrance area 11 of the first channel 10; blocks 4 are provided at both ends of the filling station 30, and the block 4 at the bottom of the filling station 30 extends to the left to the top of the first channel 10; while in embodiment 4, no bottle blocking assembly 6 and guardrail are provided, and the length of the block 4 at the bottom of the filling station 30 in embodiment 4 is less than the length of the block 4 in embodiment 5; the arrangement of the bottle blocking assembly 6 in this embodiment can refer to Figure 5 ; The bottle blocking assembly 6 at the entrance area 11 of the first channel 10 limits a certain number of bottles 002 from entering the first channel 10. The bottles 002 follow the conveyor belt of the first channel 10. When the bottles 002 at the end meet the lower block 4, the row of bottles 002 stops, but the first channel 10 continues to move. The bottle pushing mechanism works to push multiple bottles 002 horizontally to the filling table 30 for filling. Since the blocks 4 are provided on both sides of the filling table 30, when the bottles 002 on the filling table 30 are pushed to the second channel 20 for discharging, there is no need to ensure that the conveyor belt on the second channel 20 is in a stationary state.
