Description

Technical Field

[0001] The present invention relates to the technical field of filling equipment, in particular to a fully automatic standing bag granular food filling device. Background Art

[0002] Granular foods include ready-to-eat solid-liquid mixed products such as eight-treasure porridge, millet porridge, and mung bean porridge. For example, eight-treasure porridge is typically stored in cans or plastic cups, but both storage methods have their drawbacks. While canned eight-treasure porridge maintains its shelf life, it also comes with high packaging costs and the heavy cans, making it difficult to carry.

[0003] While packaging costs for Eight Treasure Porridge stored in plastic cups are significantly lower, the cups must be filled completely to eliminate air bubbles for easy sterilization. Consumers often insert a straw into the cups, but as the cups are full, the liquid overflows from the straw, creating a negative consumer experience and unsanitary conditions.

[0004] However, the stand-up pouch with a spout, a common beverage packaging, has never been used for filling eight-treasure porridge. This is because the eight-treasure porridge contains not only solid eight-treasure porridge materials but also liquid eight-treasure porridge materials, making it difficult to fill the eight-treasure porridge into the stand-up pouch with a spout through the spout of the stand-up pouch.

[0005] Currently, there are devices on the market that can fill eight-treasure porridge materials into self-supporting bags, such as the utility model patent for a filling device that uses a spouted self-supporting bag to store eight-treasure porridge with publication number CN210175304. This device uses a turntable to rotate the self-supporting bag with a spout to transfer it to the workstation of the eight-treasure porridge solid material filling device, which fills the solid material required for the eight-treasure porridge into the self-supporting bag. The turntable then transfers the spouted self-supporting bag to the workstation of the eight-treasure porridge liquid material filling device, which fills the liquid material required for the eight-treasure porridge into the self-supporting bag. However, the spout of the traditional self-supporting bag is very small, so when filling the eight-treasure porridge solid material, the filling speed is very slow, and the spout is prone to clogging. At the same time, the turntable often needs to wait until the first spouted self-supporting bag is filled before transferring the next spouted self-supporting bag to the designated workstation for continued filling, which greatly reduces production efficiency. Summary of the Invention

[0006] The technical problem to be solved by the embodiments of the present invention is to provide a fully automatic stand-up bag granular food filling device, which can realize the synchronous filling of the stand-up bag during the conveying process, increase the filling time, and effectively improve the production efficiency.

[0007] To achieve the above-mentioned object, the present invention discloses a fully automatic granular food filling device for a stand-up bag, comprising a filling and unloading mechanism, a filling turntable, a hopper mechanism, and an auxiliary filling mechanism.

[0014] Furthermore, the first circular guide rail has a first guide protrusion, and the second circular guide rail has a plurality of second guide protrusions spaced apart along the circumferential direction.

[0015] Furthermore, the first guide mechanism includes a first roller, the first roller is rotatably disposed below the rocker, and the outer contour of the first roller is slidably engaged with the first guide protrusion of the first circular guide rail;

[0016] The second guide mechanism includes a second roller, which is rotatably disposed below the flip rod, and an outer contour of the second roller is slidably engaged with a second guide protrusion of the second circular guide rail.

[0017] Furthermore, a plurality of liftable pushing plates are provided along the circumferential direction below the filling turntable, and the pushing plates are driven to rise by a lifting drive device to lift the flip rod.

[0018] Furthermore, the filling and unloading mechanism includes a storage hopper, a push plate, and several guide hoppers. A feeding channel is provided at the bottom of the storage hopper. The push plate is slidably inserted in the feeding channel. The push plate has several quantitative ports connected to the discharge port of the storage hopper.

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0034] Reference Figure 1 、 Figure 2 As shown, a fully automatic granular food filling device for a stand-up bag includes a filling and unloading mechanism 1, a filling turntable 2, a hopper mechanism 3, an auxiliary filling mechanism 4, a bag feeding mechanism 6, a bag blowing mechanism 7, and a bag receiving turntable 8. The bag feeding mechanism 6, the bag blowing mechanism 7, the filling and unloading mechanism 1, and the bag receiving turntable 8 are respectively arranged on the circumferential side of the filling turntable 2. A plurality of card slots 21 are arranged at intervals along the circumference of the outer circumference of the filling turntable 2, which are used to clamp the bag mouths of the stand-up bags output by the bag feeding mechanism 6. The filling turntable 2 is driven to rotate by a rotary drive device, so that the stand-up bags pass through the bag feeding mechanism 6, the bag blowing mechanism 7, the filling and unloading mechanism 1, and the bag receiving turntable 8 in sequence. The hopper mechanism 3 and the auxiliary filling mechanism 4 are distributed along the circumference of the filling turntable 2 and are respectively rotatably arranged on the filling turntable 2. The hopper mechanism 3 and the auxiliary filling mechanism 4 move circumferentially accordingly under the drive of the filling turntable 2.

[0035] Reference Figure 3 、 Figure 4 As shown, the hopper mechanism 3 includes a plurality of material cups 31 and a rocker 32. One end of the rocker 32 is rotatably set on the filling turntable 2. In this embodiment, the plurality of material cups 31 are divided into two groups, each group uses three material cups 31 and a rocker 32. A material cup seat 33 is provided at the end of the rocker 32. The three material cups 31 are respectively arranged on the material cup seat 33, so that the material cups 31 are linked to swing up and down through the rocker 32 to keep the material cups away from the bag mouth of the self-supporting bag or buckle the bag mouth of the self-supporting bag.

[0036] The bottom of the material cup 31 is provided with a filling hole 311, and the filling hole 311 of the material cup 31 is on the same vertical line as the slot 21 of the filling turntable 2, so that the filling hole 311 of the material cup 31 can be aligned with the bag mouth of the self-supporting bag, and the inner bottom surface of the material cup 31 is in the shape of an inverted cone, so that the material in the material cup 31 can be concentratedly poured into the self-supporting bag through the bag mouth, preventing the material from remaining in the material cup 31, and the bottom surface of the material cup 31 has a conical recess, so that the conical recess of the material cup 31 can buckle the bag mouth of the self-supporting bag, ensuring that the filling hole 311 of the material cup can be aligned with the bag mouth of the self-supporting bag, avoiding the filling hole 311 and the bag mouth being uneven, causing the bag mouth area to become smaller and affect the filling speed, or a gap between the filling hole 311 and the bag mouth, causing the material to fall out of the self-supporting bag through the gap.

[0037] Reference Figure 3 、 Figure 5 As shown, the auxiliary filling mechanism 4 includes a plurality of insertion rods 41 and a flip rod 42 corresponding to the material cup 31. The flip rod 42 is rotatably set on the filling turntable 2. The end of the flip rod 42 is provided with a cross bar 43. The top of the insertion rod 41 is set on the cross bar 43, so that the flip rod 42 links the plurality of insertion rods 41 to swing up and down, so that the insertion rod 41 extends from the upper opening of the material cup 31 to the filling hole 311, or extends from the filling hole 311 of the material cup 31 to the upper opening.

[0038] Reference Figure 6 、 Figure 7 As shown, further, a guiding mechanism 5 is provided below the filling turntable 2, a first guiding mechanism is provided below the flip rod 42, and a second guiding mechanism is provided below the rocker arm 32, so that the first guiding mechanism and the second guiding mechanism respectively drive the flip rod 42 and the rocker arm 32 to swing up and down under the guiding action of the guiding mechanism 5.

[0039] Specifically, the guiding mechanism 5 includes an annular disk 51 , a first circular guide rail 52 , and a second circular guide rail 53 . The first circular guide rail 52 and the second circular guide rail 53 are arranged in parallel on the annular disk 51 . The inner diameter of the second circular guide rail 53 is larger than the outer diameter of the first circular guide rail 52 .

[0040] Combine Figure 1As shown, the top surface of the first circular guide rail 52 is provided with a plurality of first guide protrusions 521 spaced along the circumferential direction between the filling and unloading mechanism and the bag discharging mechanism. The first guide mechanism includes a first roller, which is rotatably provided below the flip rod 42, and the outer contour of the first roller is slidably matched with the first guide protrusion 521 of the first circular guide rail 52. When the first roller slides along the first circular guide rail 52 to the first guide protrusion 521, the flip rod 42 is lifted by the first guide protrusion 521. The insertion rod 41 is driven to swing upward, so that the insertion rod 41 extends out of the material cup 31. When the first roller on the first guide protrusion 521 slides onto the first circular guide rail 52, the flip rod 42 drives the insertion rod 41 to swing downward, so that the insertion rod 41 extends into the material cup 31. The first guide protrusions 521 arranged at intervals are used to make the insertion rod 41 swing up and down continuously, thereby clearing the filling hole 311 of the material cup 31, avoiding blockage of the filling hole 311 of the material cup 31 and affecting the filling work of the self-supporting bag.

[0041] The top surface of the second circular guide rail 53 has a second guide protrusion 531 between the bag feeding mechanism 6 and the bag receiving turntable 8. The second guide mechanism includes a second roller, which is rotatably arranged below the rocker arm 32, and the outer contour of the second roller is slidably matched with the second guide protrusion of the second circular guide rail 53. When the second roller slides onto the second guide protrusion 531 along the second circular guide rail 53, the rocker arm 32 drives the material cup 31 to swing upward under the lifting action of the second guide protrusion 531, thereby making the filling hole 311 of the material cup 31 away from the bag mouth of the self-supporting bag on the filling turntable, so as to facilitate the bag feeding or bag discharging work.

[0042] When the second roller on the second guide protrusion 531 slides onto the second circular guide rail 53, the swing rod 32 drives the material cup 31 to swing downward, so that the filling hole 311 of the material cup 31 abuts against the bag mouth of the self-supporting bag, thereby facilitating the filling work of the self-supporting bag.

[0043] Several push plates corresponding to the auxiliary filling mechanisms are arranged in a liftable manner below the filling turntable 2. A lifting drive device is fixedly arranged below the push plates. In this embodiment, the lifting drive device preferably adopts a cylinder, and its telescopic end is fixedly connected to the push plate. When the equipment is shut down, the push plate is driven to rise and lift the flip rod through the lifting drive device to make the insertion rod extend out of the material cup.

[0044] Reference Figure 1 、 Figure 8 、 Figure 9As shown, the filling and unloading mechanism 1 includes a storage hopper 11, a push plate 12, and several guide hoppers 13. A feeding channel 14 is provided at the bottom of the storage hopper 11. The push plate 12 is slidably inserted in the feeding channel 14. The push plate 12 has several quantitative ports 121 connected to the discharge port of the storage hopper 11. Several guide ports 141 connected to the quantitative ports 121 are provided on the bottom of the feeding channel. Several guide hoppers are respectively arranged below the guide ports 141. A lifting platform is provided below the storage hopper 11. Several guide hoppers are respectively arranged on the lifting platform so that the lifting platform drives the several guide hoppers to extend into or out of the material cup 31.

[0045] The material in the storage hopper 11 falls into the metering port 121 of the push plate 12, and the push drive device 15 drives the push plate 12 to push the material into the guide hopper respectively, so that the material falls into the material cup 31 through the guide hopper, preventing the material from splashing out of the material cup 31 during the unloading process, causing food waste.

[0046] The bag blowing mechanism 7 includes several blowing heads, which are respectively arranged above the material cup and connected to an air source. By turning on the air source, the blowing heads blow air into the inside of the self-supporting bag, causing the inside of the self-supporting bag to bulge, making it easier for the material to be better filled inside.

[0047] Reference Figures 1-9 As shown, the specific working process is as follows:

[0048] First, the self-supporting bags are transported one by one toward the filling turntable 2 through the bag feeding mechanism 6. When the card slot 21 of the filling turntable 2 passes the bag feeding mechanism 6, the card slot 21 of the filling turntable 2 clamps the bag mouth of the first self-supporting bag at the front end of the bag feeding mechanism 6, and the self-supporting bag is conveyed to the bottom of the bag blowing mechanism 7, so that the bag blowing mechanism 7 blows air into the self-supporting bag to make the inside of the self-supporting bag bulge, and then the filling turntable 2 conveys the self-supporting bag to the bottom of the filling unloading mechanism 1.

[0049] Next, the lifting platform drives several guide hoppers to descend so that the discharge port of the guide hopper extends into the material cup 31, and the metering ports 121 on the push plate 12 respectively receive the materials falling from the storage hopper 11. The push drive device 15 drives the push plate 12 to move toward the guide hopper until the metering port 121 on the push plate 12 is chain-connected with the guide port 141, so that the material in the metering port 121 falls into the guide hopper, and the material is respectively introduced into the material cup 31 through the guide hopper. Then the lifting platform drives the storage hopper 11 to rise to keep the guide hopper away from the material cup 31.

[0050] After the material cup 31 completes receiving the material, the filling turntable 2 drives the material cup 31 to be transported toward the bag receiving turntable 8. At the same time, during the transportation process of the filling turntable 2, the material in the material cup 31 is poured into the self-supporting bag through the filling hole 311 under the action of its own weight, and the insertion rod 41 continuously swings up and down under the action of the several first guide protrusions 521 of the first circular guide rail 52 during the above-mentioned transportation process, so that the insertion rod 41 can reciprocate in the material cup 31, thereby clearing the filling hole 311 of the material cup 31 and preventing the material from being blocked in the material cup 31 and affecting the filling work. When the self-supporting bag is conveyed to the bag receiving turntable 8, the material cup 31 swings upward under the action of the second guide protrusion 531 of the second circular guide rail 53, so that the filling hole 311 of the material cup 31 is separated from the bag mouth of the self-supporting bag, so that the bag receiving turntable 8 can take out the bag mouth that has completed filling on the filling turntable 2, thereby realizing synchronous filling during the transportation process of the self-supporting bag.

[0051] Of course, the above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They cannot be used to limit the scope of protection of the present invention.
