Description

Technical Field

[0001] This invention relates to the field of filling technology, and more specifically to liquid filling equipment. Background Technology

[0002] Currently, there is an increasing number of prefabricated barrels on the market. These products typically involve placing an empty barrel into a perforated hole on a filling template, then moving the filling template to the filling area via a motor, and finally filling it automatically by a filling machine.

[0003] Because the perforations on the filling template are fixed and match the dimensions of the precast barrels, the factory needs to replace all the filling templates when it wants to fill precast barrels of different sizes. This wastes production time and reduces production efficiency. Furthermore, it requires custom-made filling templates of various sizes, which also increases overall production costs. Summary of the Invention

[0004] In view of this, the present invention provides a liquid filling device to solve the problem of needing to replace all filling templates when filling prefabricated barrels of different sizes.

[0005] In a first aspect, the present invention provides a liquid filling apparatus, the liquid filling apparatus comprising:

[0006] A conveying device suitable for conveying empty buckets; along the conveying direction, the conveying device has multiple conveying channels arranged side by side for conveying the empty buckets; the conveying channels are suitable for accommodating the largest size of the empty buckets;

[0007] A limiting rod chain is installed on the conveying equipment; along the conveying direction, the limiting rod chain has multiple limiting rods arranged in parallel, and a limiting space is formed between two adjacent limiting rods and two adjacent guide rods; the limiting rod chain sequentially moves each empty bucket into each limiting space; the limiting space is suitable for accommodating the largest size of the empty bucket.

[0008] Beneficial effects: By setting up conveying equipment and limiting rod chains, the embodiments of the present invention can accommodate the largest size of empty buckets because the conveying channel and limiting space can accommodate the largest size of empty buckets. Therefore, there is no need to change the template during the conveying process, which can ensure that the conveying equipment and limiting rod chains are compatible with all sizes of empty buckets, thereby improving production efficiency to a certain extent.

[0009] In one alternative embodiment, the conveying device has multiple guide rods arranged side by side, with the conveying channel formed between two adjacent guide rods.

[0010] In one alternative implementation, two adjacent guide rods have working states of being close to each other and far apart from each other.

[0011] Beneficial effects: By enabling adjacent guide rods to operate in states of approaching and moving away from each other, the spacing between the two guide rods can be adjusted according to the specifications of the empty bucket, ensuring that the guide rods can precisely limit the empty bucket and prevent the empty bucket from wobbling due to a large distance between the guide rods and the empty bucket. This ensures that the empty bucket can move stably on the conveyor chain.

[0012] In one alternative embodiment, the conveying device is further provided with a limiting component, which is adapted to adjust the distance between two adjacent empty buckets in each conveying channel.

[0013] In one optional implementation, the limiting component includes:

[0014] A pair of limiting stops are located at the end of the conveying equipment; each limiting stop is provided with multiple baffles, and the baffles correspond one-to-one with the conveying channel; the limiting stops have working states of approaching and moving away from the conveying equipment, so that only one empty bucket can be accommodated between two adjacent baffles.

[0015] Beneficial effects: By setting a limiting stop, the limit stop falls when the container approaches the conveying equipment, which can block the empty container from being conveyed forward. This can effectively control the distance between two adjacent empty containers, ensuring that each empty container can enter the limiting space and, under the guidance of the sorting system, can enter the hollow hole of the discharge system, ensuring that the empty container can be filled normally.

[0016] In one optional implementation, the limiting component further includes:

[0017] A separating blocking element is located at the head end of the conveying equipment along the conveying direction of the conveying equipment;

[0018] The sterilization blocking component is located downstream of the separating blocking component along the conveying direction of the conveying equipment;

[0019] The separating barrier and the sterilizing barrier are spaced apart, and both have working states that are close to and far from the conveying equipment;

[0020] The liquid filling equipment also includes a hydrogen peroxide sterilization device, which sterilizes empty containers located between the separating barrier and the sterilization barrier.

[0021] Beneficial effects: By setting up a separator and a sterilization barrier, when an empty bucket enters between the separator and the sterilization barrier, the separator and the sterilization barrier fall down and abut against the conveying equipment, making the empty bucket between the separator and the sterilization barrier unable to move, so that the empty bucket can be sterilized by the sterilization equipment.

[0022] In one optional implementation, the limiting component further includes:

[0023] The drying blocking component is located downstream of the sterilization blocking component and upstream of the limiting stop component, along the conveying direction of the conveying equipment.

[0024] The drying blocking component has operating states that are close to and far from the conveying equipment;

[0025] The liquid filling equipment also includes a drying device that dries empty containers located between the sterilization barrier and the drying barrier.

[0026] Beneficial effects: By setting up a drying barrier, when an empty barrel enters between the sterilization barrier and the drying barrier, the sterilization barrier and the drying barrier fall down and abut against the conveying equipment, making the empty barrel between the sterilization barrier and the drying barrier unable to move. Thus, the empty barrel can be dried by the drying equipment to prepare for subsequent filling.

[0027] In one alternative embodiment, the conveying device is a conveyor chain, which is driven forward by a power device.

[0028] In one optional embodiment, the end of the conveying device is provided with a bucket drop guide; the bucket drop guide is provided with a plurality of bucket drop guide grooves, one end of the bucket drop guide groove is connected to each conveying channel of the conveying device, and the other end of the bucket drop guide groove extends toward the discharge system.

[0029] Beneficial effects: By setting a bucket guide in this embodiment of the invention, after the empty bucket is transported to the end of the conveying equipment, it will slide directly into the hollow hole through the bucket guide, which can prevent the empty bucket from falling directly into the hollow hole, ensuring the integrity of the empty bucket and preventing fragile empty buckets from breaking or cracking when falling.

[0030] In one alternative embodiment, the conveying device is further provided with a pressing rod located above each empty bucket in the conveying channel; the pressing rod has positions close to and far from the empty bucket.

[0031] Beneficial effects: By setting a pressing rod, the distance between the pressing rod and the empty bucket can be adjusted according to the actual specifications of the empty bucket, ensuring that the pressing rod can abut against the empty bucket, thereby limiting the empty bucket and preventing the empty bucket from shaking due to a large distance between the pressing rod and the empty bucket, thus ensuring that the empty bucket can move stably on the conveying equipment.

[0032] In one optional embodiment, the limiting lever chain includes:

[0033] A pair of drive belts extend along the conveying direction; a plurality of limiting rods are arranged side by side between the two drive belts;

[0034] A power motor is connected to the transmission belt; under the driving action of the power motor, the transmission belt drives the limiting rod to move.

[0035] In one optional embodiment, the liquid filling apparatus further includes:

[0036] The discharge system is connected to the end of the conveying equipment; the discharge system is provided with perforations corresponding to the specifications of the empty barrel;

[0037] The filling system is equipped with multiple filling machines; each filling machine corresponds to the number of conveying channels.

[0038] In one alternative implementation, multiple filling machines fill at least two liquids.

[0039] Beneficial effects: By setting up multiple filling machines, the present invention can simultaneously fill different types of liquids according to actual market demand, thus eliminating the need to replace filling machines, completely eliminating the time wasted on replacing filling machines, and thereby improving production efficiency.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0049] Currently, prefabricated barrels are increasingly common in the market. These products typically involve placing an empty barrel into a perforated filling template, which is then moved to the filling area by a motor, and finally filled automatically by a filling machine. Because the perforated holes on the filling template are fixed and matched to the size of the prefabricated barrel, factories need to replace all the filling templates when they want to fill barrels of different sizes. This wastes production time and reduces efficiency. Furthermore, custom-made filling templates of various sizes are required, which also increases overall production costs.

[0050] In view of this, the present invention provides a liquid filling device to solve the problem of needing to replace all filling templates when filling prefabricated barrels of different sizes.

[0051] The following is combined with Figures 1 to 2The following describes embodiments of the present invention.

[0052] According to an embodiment of the present invention, a liquid filling device is provided, which includes: a conveying device 1, a pretreatment system, a sorting system, a discharge system 5, and a filling system.

[0053] Specifically, in this embodiment of the invention, the conveying device 1 is adapted to convey empty buckets 8. Along the conveying direction, multiple conveying channels for conveying the empty buckets 8 are arranged side-by-side on the conveying device 1. Furthermore, the conveying channels are adapted to accommodate the largest size of the empty buckets 8. Therefore, when changing the size of the empty bucket 8, it is not necessary to change the conveying channels. The conveying device 1 can be a conveyor, a conveyor belt, or other conveying device.

[0054] Furthermore, a bucket dropping device 7 can be installed at the head end of the conveyor device 1. The bucket dropping device 7 contains empty buckets 8. When the bucket dropping device 7 is aligned with the conveyor device 1, the empty buckets 8 can be directly dropped onto the conveyor device 1 for conveying. Of course, the empty buckets 8 can also be placed onto the conveyor device 1 manually.

[0055] Furthermore, in this embodiment of the invention, a limiting rod chain 4 is disposed on the conveying device 1. The limiting rod chain 4 has a structure similar to a track, and when the limiting rod chain 4 rotates, its bottom moves synchronously with the conveying device 1.

[0056] Along the conveying direction, the limiting rod chain 4 has multiple limiting rods 41 arranged in parallel. A limiting space 42 is formed between two adjacent limiting rods 41 and two adjacent guide rods 9. When the limiting rod chain 4 is activated, the upper limiting rod 41 gradually moves downwards towards the empty bucket 8, then moves the empty bucket 8 along the conveying direction, sequentially moving each empty bucket 8 into each limiting space 42. After the empty bucket 8 is conveyed to the discharge system 5, the lower limiting rod 41 gradually moves upwards, moving in the opposite direction of the conveying, thus reciprocating like a conveyor belt. The limiting space 42 is suitable for accommodating the largest size of the empty bucket 8, ensuring that the limiting space 42 can accommodate the largest empty bucket 8, thus eliminating the need for replacement.

[0057] Of course, since the limit rod chain 4 and the guide assembly can be directly connected or partially overlapped, it is acceptable as long as it does not affect their mutual operation.

[0058] With this configuration, this embodiment of the invention, by setting up the conveying device 1 and the limiting chain 4, ensures that the conveying channel and the limiting space 42 can accommodate the largest size of empty bucket 8. Therefore, there is no need to change the template during the conveying process, ensuring that the conveying device 1 and the limiting chain 4 can be compatible with all sizes of empty buckets 8, which can improve production efficiency to a certain extent. At the same time, by setting up multiple filling machines 6, empty buckets 8 on all conveying channels can be filled simultaneously, which can improve production efficiency.

[0059] Furthermore, in an optional embodiment, multiple guide rods 9 are arranged side-by-side along the conveying direction on the conveying device 1, with intervals between them, so that a conveying channel for conveying the empty bucket 8 is formed between adjacent guide rods 9. Moreover, the distance between adjacent guide rods 9 can accommodate the largest size of the empty bucket 8. That is, the guiding assembly can be placed as a whole on the conveying device 1, and when the guide rods 9 on the guiding assembly are fixedly connected, the distance between adjacent guide rods 9 is not adjustable.

[0060] Furthermore, in an optional embodiment, adjacent guide rods 9 have working states of being close to each other and far apart from each other. That is, the guide rods 9 on the guide assembly are flexibly installed, and the distance between adjacent guide rods 9 can be adjusted. The adjustment method can be manual or automatic adjustment via a drive device. Therefore, when changing the size of the empty bucket 8, only the distance between the guide rods 9 needs to be adjusted.

[0061] Of course, this embodiment is merely an example of the adjustment method, but it does not limit the scope of the invention. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0062] With this configuration, the present invention allows two adjacent guide rods 9 to have working states of being close to each other and far apart from each other. The distance between the two guide rods 9 can be adjusted according to the specifications of the empty bucket 8, ensuring that the guide rods 9 can just limit the empty bucket 8 and prevent the empty bucket 8 from shaking due to a large distance between the guide rods 9 and the empty bucket 8. This ensures that the empty bucket 8 can move stably on the conveyor chain.

[0063] Furthermore, in this embodiment of the invention, the conveying device 1 is also provided with a limiting component 10, which is adapted to adjust the distance between two adjacent empty barrels 8 in each conveying channel. That is, during the conveying process, the distance between two adjacent empty barrels 8 is small, making the empty barrels 8 relatively dense. During filling or dropping, it is impossible to accurately identify and fill or accurately drop the barrels to the predetermined position. Therefore, it is necessary to adjust the distance between two adjacent empty barrels 8 through the limiting component 10 so that the spacing between the empty barrels 8 meets the overall distance requirements of the equipment.

[0064] Further, in an optional embodiment, the limiting component 10 includes a pair of limiting stops 101 located at the end of the conveying device 1. Each limiting stop 101 is provided with multiple baffles, each baffle corresponding to a conveying channel. The limiting stops 101 have working states of approaching and moving away from the conveying device 1; that is, when the limiting stop 101 causes the baffles to fall, it blocks the conveying channel, preventing the empty buckets 8 from being conveyed forward, thus allowing adjustment of the spacing between two adjacent empty buckets 8. Simultaneously, only one row of empty buckets 8 needs to be accommodated between two limiting stops 101; that is, only one empty bucket 8 is accommodated between two baffles in each conveying channel. After adjusting the spacing, the limiting stops 101 cause the baffles to rise, allowing the conveying channel to move normally. Then the limiting stops 101 fall again to adjust the spacing of the next empty bucket 8, and so on.

[0065] Finally, the conveying device 1 will transport each row of empty buckets 8 with the adjusted spacing into the limiting space 42.

[0066] With this configuration, the present invention embodiment sets up a limiting stop 101. When the empty bucket 8 approaches the conveying device 1, the limiting stop 101 falls down, which can block the empty bucket 8 from being conveyed forward. This can effectively control the distance between two adjacent empty buckets 8, ensuring that each empty bucket 8 can enter the limiting space 42. At the same time, under the guidance of the sorting system, it can also enter the hollow hole 51 of the discharge system 5, ensuring that the empty bucket 8 can be filled normally.

[0067] Furthermore, in an optional embodiment, the limiting component 10 further includes a separating blocking member 102 and a sterilizing blocking member 103. Specifically, the separating blocking member 102 is located at the head end of the conveying device 1 along the conveying direction of the conveying device 1, and the sterilizing blocking member 103 is located downstream of the separating blocking member 102 along the conveying direction of the conveying device 1.

[0068] The separating barrier 102 and the sterilizing barrier 103 operate in the same way as the limiting barrier 101. Furthermore, the separating barrier 102 and the sterilizing barrier 103 are spaced apart and each has operating states that are close to and far from the conveying device 1.

[0069] Furthermore, in this embodiment of the invention, the liquid filling equipment also includes a hydrogen peroxide sterilization device 2. When both the separating barrier 102 and the sterilization barrier 103 are close to the conveying device 1, the empty barrel 8 located between the separating barrier 102 and the sterilization barrier 103 stops moving, so that the hydrogen peroxide sterilization device 2 sterilizes the empty barrel 8 located between the separating barrier 102 and the sterilization barrier 103.

[0070] With this configuration, in this embodiment of the invention, by setting up a separating barrier 102 and a sterilization barrier 103, when an empty bucket 8 enters between the separating barrier 102 and the sterilization barrier 103, the separating barrier 102 and the sterilization barrier 103 fall down and abut against the conveying device 1, so that the empty bucket 8 between the separating barrier 102 and the sterilization barrier 103 cannot move, thereby allowing the empty bucket 8 to be sterilized by the sterilization device.

[0071] Furthermore, in an optional embodiment, the limiting component 10 further includes a drying blocking member 104, which is located downstream of the sterilization blocking member 103 and upstream of the limiting member 101 along the conveying direction of the conveying device 1. The drying blocking member 104 operates in the same way as the limiting member 101, that is, the drying blocking member 104 has working states that are close to and far from the conveying device 1.

[0072] Furthermore, in this embodiment of the invention, the liquid filling equipment also includes a drying device 3. When both the sterilization barrier 103 and the drying barrier 104 are close to the conveying device 1, the drying device 3 dries the empty barrel 8 located between the sterilization barrier 103 and the drying barrier 104.

[0073] With this configuration, in this embodiment of the invention, by setting up a drying blocking member 104, when the empty barrel 8 enters between the sterilization blocking member 103 and the drying blocking member 104, the sterilization blocking member 103 and the drying blocking member 104 fall down and abut against the conveying device 1, so that the empty barrel 8 between the sterilization blocking member 103 and the drying blocking member 104 cannot move, thereby allowing the empty barrel 8 to be dried by the drying device 3, preparing it for subsequent filling.

[0074] In actual operation, the empty bucket 8 is first dropped onto the conveyor 1 by the bucket dropping device 7, and then enters the limiting component 10 after passing through the conveying channel. When the empty bucket 8 reaches the position of the separating blocking member 102, it is intercepted by the separating blocking member 102 and stops moving. Then the separating blocking member 102 retracts upward. When the empty bucket 8 reaches the position of the sterilization blocking member 103, the sterilization blocking member 103 falls and continues to block the buckets coming from behind. The empty bucket 8 undergoes hydrogen peroxide sterilization between the separating blocking member 102 and the sterilization blocking member 103. After sterilization, the sterilization blocking member 103 retracts upward, and the empty bucket 8 between the separating blocking member 102 and the sterilization blocking member 103 is discharged. After it is completely discharged, the sterilization blocking member 103 falls, and when the empty bucket 8 is conveyed to the position of the drying blocking member 104, the drying blocking member 104 falls, and the empty bucket 8 stops moving. Then the empty bucket 8 between the sterilization blocking member 103 and the drying blocking member 104 is dried. After drying is complete, the drying blocking member 104 retracts upward, and the empty barrel 8 stops being discharged when it reaches the position of the first limiting member 101. The first limiting member 101 then retracts upward, and the empty barrel 8 stops being discharged when it reaches the position of the second limiting member 101. The first limiting member 101 then falls down, blocking the rear row of empty barrels 8, ensuring that there is only one row of empty barrels 8 between the two limiting members 101.

[0075] Furthermore, in an optional embodiment, the conveying device 1 is a conveying chain, which is composed of a mesh plate chain and is driven forward by a power device.

[0076] Furthermore, in an optional embodiment, a bucket drop guide is provided at the end of the conveying device 1. The bucket drop guide is provided with multiple bucket drop guide grooves, one end of which is connected to each conveying channel of the conveying device 1, and the other end of which extends towards the discharge system 5.

[0077] With this configuration, in this embodiment of the invention, after the empty bucket 8 is conveyed to the end of the conveying device 1, it will slide directly into the hollow hole 51 through the bucket guide, which can prevent the empty bucket 8 from falling directly into the hollow hole 51, thus ensuring the integrity of the empty bucket 8 and preventing the fragile material empty bucket 8 from breaking or cracking when falling.

[0078] Furthermore, in an optional embodiment, the conveying device 1 is also provided with a pressing rod, which is located above each empty bucket 8 in the conveying channel, and the pressing rod has positions close to and far from the empty bucket 8. That is, the pressing rod is flexibly installed, and the distance between the pressing rod and the empty bucket 8 can be adjusted. The adjustment method can be manual or automatic adjustment via a drive device.

[0079] Of course, this embodiment is merely an example of the adjustment method, but it does not limit the scope of the invention. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0080] With this configuration, the distance between the pressing rod and the empty bucket 8 can be adjusted according to the actual specifications of the empty bucket 8, ensuring that the pressing rod can abut against the empty bucket 8. This limits the empty bucket 8 and prevents it from shaking due to a large distance between the pressing rod and the empty bucket 8, thus ensuring that the empty bucket 8 can move stably on the conveying device 1.

[0081] Furthermore, in an optional embodiment, the limiting rod chain 4 includes a transmission belt and a power motor.

[0082] Specifically, in this embodiment of the invention, a pair of drive belts extend along the conveying direction, and a plurality of limiting rods 41 are arranged side by side between the two drive belts. One end of each limiting rod 41 is connected to one of the drive belts, and the other end of each limiting rod 41 is connected to the other drive belt, forming a track-like structure. A power motor is connected to the drive belts; under the driving action of the power motor, the drive belts drive the limiting rods 41 to move. When the limiting rods 41 move, they also push the empty bucket 8 forward until it reaches the discharge system 5.

[0083] Furthermore, in this embodiment of the invention, the limiting rod 41 and the transmission belt can be either fixedly connected or detachably connected. For a fixed connection, welding, bonding, or other methods can be used. For a detachable connection, screws, clips, or magnetic attraction can be used for fixation.

[0084] The following are examples of detachable connection methods. For instance, additional fixing plates can be provided around the edge of the transmission belt. Those skilled in the art can change the number of fixing plates according to actual needs, such as 1, 2, 3, 4, etc. Screw holes are then made on the fixing plates. Another screw hole is made on the limiting rod 41 at the corresponding screw hole position. Screws are then passed through the screw holes on the fixing plates and the limiting rod 41 in sequence to connect the transmission belt to the limiting rod 41. Furthermore, when using a snap-fit ​​and slot method for fixing, snap-fits can be additionally provided around the edge of the transmission belt. Those skilled in the art can change the number of snap-fits according to actual needs, such as 1, 2, 3, 4, etc. A slot is then made on the limiting rod 41 at the corresponding snap-fit ​​position to engage with the snap-fit. The snap-fit ​​on the transmission belt is then directly inserted into the slot on the limiting rod 41, thereby connecting the transmission belt to the limiting rod 41. When fixing by magnetic attraction, additional magnetic sheets can be set around the edge of the transmission belt. Those skilled in the art can change the number of magnetic sheets according to the actual situation, such as 1, 2, 3, 4, etc. Then, opposite magnetic sheets that can attract the magnetic sheets are made on the limiting rod 41 at the position corresponding to the magnetic sheets. Then, the magnetic sheets on the transmission belt are directly aligned with the opposite magnetic sheets embedded on the limiting rod 41, thereby magnetically connecting the transmission belt and the limiting rod 41.

[0085] Of course, this embodiment is merely an example of fixed connection and detachable connection, but it does not limit the scope of the invention. Those skilled in the art can make changes according to the actual situation to achieve the same technical effect.

[0086] Furthermore, in this embodiment of the invention, the liquid filling equipment also includes a discharge system 5 and a filling machine 6.

[0087] Specifically, the discharge system 5 is connected to the end of the conveying device 1, and the discharge system 5 is provided with a perforated hole 51 corresponding to the size of the empty bucket 8. Since the perforated hole 51 is fixed, when changing the size of the empty bucket 8, it is necessary to replace the perforated template of the discharge system 5. The perforated template has perforated holes 51, so that the perforated holes 51 on the replaced perforated template are adapted to the size of the empty bucket 8. Compared with the current overall replacement method, this embodiment can significantly reduce the cost of equipment replacement.

[0088] For the movement of the perforated template, it can be fixed to a chain, and the chain can be driven forward by a motor. Alternatively, the perforated template can be directly placed on a conveyor for transport.

[0089] Furthermore, in this embodiment of the invention, the filling system is provided with a plurality of filling machines 6, each filling machine 6 corresponding to the number of conveying channels, such that each filling machine 6 fills the empty barrels 8 in its respective conveying channel.

[0090] Furthermore, in an alternative embodiment, the multiple filling machines 6 fill at least two types of liquids. For example, when filling yogurt, each filling machine 6 can fill different flavors of yogurt, so that multiple empty containers 8 can be filled at the same time, thereby improving work efficiency.

[0091] With this configuration, the present invention can fill different types of liquids simultaneously according to actual market demand by setting up multiple filling machines 6, thereby eliminating the need to replace the filling machines 6, completely eliminating the time wasted on replacing the filling machines 6, and thus improving production efficiency.

[0092] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
