Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical production machinery and equipment, and in particular to a filling device and method for irregularly shaped bottles. Background Technology

[0002] The production process for soft spray bottles (which are irregularly shaped) generally involves weighing before filling, weighing after filling, and capping. To improve production efficiency, soft spray bottles are typically produced using an assembly line process. However, current production methods require pauses at each workstation to allow the corresponding workstation to complete its operation before intermittently conveying the bottle to the next station. Because the actions at each workstation are difficult to coordinate with the conveying mechanism, it's impossible for the conveying mechanism to pause simultaneously at each workstation and for all workstations to operate simultaneously. This results in long downtime, low efficiency, and high production costs. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a special-shaped bottle filling production device and method with short total downtime, high working efficiency and low production cost.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A bottle filling production system for irregularly shaped bottles includes a base, a conveying mechanism mounted on the base, and a front weighing station, a filling station, a rear weighing station, and a capping station arranged sequentially along the conveying direction of the conveying mechanism. The conveying mechanism is provided with multiple bottle holders arranged at intervals along the conveying mechanism, each bottle holder being used to hold a group of irregularly shaped bottles. The base is also provided with a weighing device, and a transfer device is provided between the weighing station and the weighing device. The conveying mechanism conveys intermittently for a predetermined time, conveying forward the distance of one bottle holder each time.

[0006] As a further improvement to the above technical solution:

[0007] The bottle holder is provided with a row of receiving holes for holding a group of irregularly shaped bottles, and each of the weighing machines located below the bottle holder is provided with a bottle-lifting device for pushing the irregularly shaped bottles out of the receiving holes.

[0008] The bottle-top device includes a bottle-top seat and a bottle-top drive for driving the bottle-top seat to rise and fall. The top of the bottle-top seat is provided with a row of bottle-top columns that correspond one-to-one with a row of receiving holes on the upper bottle-supporting seat.

[0009] The weighing device includes a weighing bottle holder, a weighing device located at the bottom of the weighing bottle holder, a bottle support block that is lifted and lowered inside the weighing bottle holder, and a first lifting drive for driving the bottle support block to lift and lower.

[0010] The weighing device also includes a bottle placement platform located on one side of the weighing bottle holder.

[0011] The filling station is equipped with a lifting frame and a second lifting drive for driving the lifting frame to move up and down. The lifting frame is equipped with a row of filling needles.

[0012] The lifting frame has a row of inflation needles in front of and / or behind the filling needles.

[0013] The conveying mechanism has a capping inspection and rejection station and a bottle exit station arranged sequentially along the conveying direction of the conveying mechanism downstream of the capping station.

[0014] The conveying mechanism has a positive and negative bottle detection station upstream of the previous weighing station.

[0015] A method for filling irregularly shaped bottles, using the aforementioned irregularly shaped bottle filling system, includes the following steps:

[0016] S1. Bottle placement: Bottles are placed intermittently at each bottle holder;

[0017] S2, Front Weighing: The 2n-1th bottle holder transports the 2n-1th group of irregularly shaped bottles to the front weighing station. The transfer device transfers the 2n-1th group of irregularly shaped bottles on the front weighing station to the weighing device for empty bottle weighing. After weighing, the transfer device transfers the 2n-1th group of irregularly shaped bottles on the weighing device to the 2nth bottle holder.

[0018] S3. Filling: The 2nth bottle holder transports the 2n-1th group of irregularly shaped bottles to the filling station for filling;

[0019] S4. Post-weighing: The 2nth bottle holder transports the 2n-1th group of irregularly shaped bottles to the post-weighing station. The transfer device transfers the 2n-1th group of irregularly shaped bottles from the post-weighing station to the weighing device for full-bottle weighing. After weighing, the transfer device transfers the 2n-1th group of irregularly shaped bottles from the weighing device to the 2n+1th bottle holder.

[0020] S5. Capping: The (2n+1)th bottle holder transports the (2n-1)th group of irregularly shaped bottles to the capping station for capping; where n is a positive integer.

[0021] Compared with the prior art, the advantages of the present invention are as follows:

[0022] The irregular-shaped bottle filling production system of the present invention features multiple bottle holders arranged at intervals along the conveying mechanism. Each bottle holder holds a group of irregular-shaped bottles. During production, the conveying mechanism can maintain intermittent, predetermined-duration conveying, advancing the distance of one bottle holder at a time. Conveying and bottle placement are matched; that is, bottles are placed intermittently at each bottle holder, meaning a bottle is placed at one holder before a bottle is placed at the next. This allows the actions of each workstation to be synchronized with the conveying mechanism, enabling simultaneous pauses at each workstation and simultaneous actions at each workstation. This reduces the total downtime of the conveying mechanism, increases work efficiency, and lowers production costs. The irregular-shaped bottle filling production system of this invention features short total downtime, high work efficiency, and low production costs.

[0023] In the irregular bottle filling production system of the present invention, when the bottle support of the conveying mechanism reaches the weighing station, the bottle-topping device pushes out the irregular bottles in each support hole on the bottle support, so that the transfer device can grab them.

[0024] The irregular-shaped bottle filling production system of the present invention uses a transfer device to first transfer the irregular-shaped bottles to a bottle placement platform, and then place them one by one onto a weighing device for weighing. In this way, only one weighing device is needed to weigh all the irregular-shaped bottles, reducing the cost of setting up multiple weighing devices. Weighing devices are expensive, and the more devices used, the higher the cost.

[0025] The irregular-shaped bottle filling production method of the present invention involves a conveying mechanism that maintains intermittent, predetermined conveying time, advancing the distance of one bottle holder at a time. The conveying and bottle placement are matched; that is, bottles are placed intermittently on each bottle holder, meaning a bottle is placed on one holder before a bottle is placed on the next. This allows the actions of each workstation to be matched with the conveying mechanism, enabling the conveying mechanism to pause simultaneously at each workstation and all workstations to operate simultaneously. This reduces the total downtime of the conveying mechanism, increases work efficiency, and lowers production costs. This irregular-shaped bottle filling production method features short total downtime, high work efficiency, and low production costs. Attached Figure Description

[0040] Example 1:

[0041] Figures 1 to 9An embodiment of the irregular-shaped bottle filling production system of the present invention is shown. The irregular-shaped bottle filling production system includes a base 9, a conveying mechanism 1 disposed on the base 9, and a front weighing station 2, a filling station 3, a rear weighing station 4, and a capping station 5 arranged sequentially along the conveying direction of the conveying mechanism 1. The conveying mechanism 1 is provided with a plurality of bottle holders 6 arranged at intervals along the conveying mechanism 1. Each bottle holder 6 is used to place a group of irregular-shaped bottles. The base 9 is also provided with a weighing device 7. A transfer device 8 is provided between the weighing station and the weighing device 7. The conveying mechanism 1 conveys intermittently for a predetermined time, and each time it conveys forward the distance of one bottle holder 6.

[0042] First, bottles are intermittently placed in each bottle holder 6. Second, the first bottle holder 6 transports the first group of irregularly shaped bottles to the front weighing station 2. The transfer device 8 transfers the first group of irregularly shaped bottles from the front weighing station 2 to the weighing device 7 for empty bottle weighing. After weighing, the transfer device 8 transfers the first group of irregularly shaped bottles from the weighing device 7 to the second bottle holder 6. Next, the second bottle holder 6 transports the first group of irregularly shaped bottles to the filling station 3 for filling. Then, the second bottle holder 6 transports the first group of irregularly shaped bottles to the rear weighing station 4. The transfer device 8 transfers the first group of irregularly shaped bottles from the rear weighing station 4 to the weighing device 7 for full bottle weighing. After weighing, the transfer device 8 transfers the first group of irregularly shaped bottles from the weighing device 7 to the third bottle holder 6. Finally, the third bottle holder 6 transports the first group of irregularly shaped bottles to the capping station 5 for capping. Following this pattern, the production process of this irregular-shaped bottle filling system is as follows: First, bottles are intermittently placed on each bottle holder 6; second, the (2n-1)th bottle holder 6 transports the (2n-1)th group of irregular-shaped bottles to the front weighing station 2, and the transfer device 8 transfers the (2n-1)th group of irregular-shaped bottles on the front weighing station 2 to the weighing device 7 for empty bottle weighing. After weighing, the transfer device 8 transfers the (2n-1)th group of irregular-shaped bottles on the weighing device 7 to the 2nth bottle holder 6; then, the 2nth bottle holder 6 places the (2n-1)th group of irregular-shaped bottles... The bottles are transported to filling station 3 for filling; then, the 2nth bottle holder 6 transports the 2n-1th group of irregularly shaped bottles to the weighing station 4. The transfer device 8 transfers the 2n-1th group of irregularly shaped bottles from the weighing station 4 to the weighing device 7 for full-bottle weighing. After weighing, the transfer device 8 transfers the 2n-1th group of irregularly shaped bottles from the weighing device 7 to the 2n+1th bottle holder 6; finally, the 2n+1th bottle holder 6 transports the 2n-1th group of irregularly shaped bottles to the capping station 5 for capping; n is a positive integer.

[0043] This irregular-shaped bottle filling production system features multiple bottle holders 6 spaced along the conveyor mechanism 1. Each bottle holder 6 holds a group of irregular-shaped bottles. During production, the conveyor mechanism 1 can maintain intermittent, predetermined conveying time, advancing the distance of one bottle holder 6 at a time. The conveying and bottle placement are matched; that is, bottles are placed intermittently on each bottle holder 6, meaning that a bottle is placed on one bottle holder 6 before a bottle is placed on the next. This allows the actions of each station to be synchronized with the conveyor mechanism 1, enabling simultaneous pauses at each station and simultaneous actions at each station. This reduces the total downtime of the conveyor mechanism 1, increases work efficiency, and lowers production costs. This irregular-shaped bottle filling production system boasts short total downtime, high work efficiency, and low production costs.

[0044] In this embodiment, as Figure 3 , Figure 4 and Figure 6 As shown, the bottle holder 6 has a row of receiving holes 61 for holding a group of irregularly shaped bottles. Each weighing station is located below the bottle holder 6 and is equipped with a bottle-lifting device 21 for pushing the irregularly shaped bottles out of the receiving holes 61. When the bottle holder 6 of the conveying mechanism 1 reaches the weighing station, the bottle-lifting device 21 pushes the irregularly shaped bottles out of the receiving holes 61 on the bottle holder 6, making it easier for the transfer device 8 to grab them.

[0045] In this embodiment, as Figures 3 to 5 As shown, the bottle-topping device 21 includes a bottle-topping seat 211 and a bottle-topping drive 212 for driving the bottle-topping seat 211 to rise and fall. The top of the bottle-topping seat 211 is provided with a row of bottle-topping posts 213 that correspond one-to-one with a row of receiving holes 61 on the upper bottle-receiving seat 6. In this way, the bottle-topping drive 212 drives the bottle-topping seat 211 to rise, and each bottle-topping post 213 can push out all the irregularly shaped bottles on the bottle-receiving seat 6 at once, resulting in high bottle-topping efficiency.

[0046] In this embodiment, as Figures 7 to 9 As shown, the weighing device 7 includes a weighing bottle holder 71, a weighing device 72 located at the bottom of the weighing bottle holder 71, a bottle-supporting block 73 that is lifted and lowered within the weighing bottle holder 71, and a first lifting drive 74 for driving the bottle-supporting block 73 to rise and fall. Weighing process: The transfer device 8 transfers the irregularly shaped bottle pushed out by the bottle-lifting device 21 to the bottle-supporting block 73 within the weighing bottle holder 71 (during bottle entry, the first lifting drive 74 keeps the bottle-supporting block 73 at a high position). The first lifting drive 74 drives the bottle-supporting block 73 to descend, causing it to fall onto the weighing device 72, where the weight of the irregularly shaped bottle is measured. After weighing, the first lifting drive 74 drives the bottle-supporting block 73 to rise to a high position, ready for the transfer device 8 to transfer the lifted irregularly shaped bottle.

[0047] The transfer device 8 includes a bottle suction device. During the process of the transfer device 8 picking up irregularly shaped bottles from the bottle holder 6 and transferring them to the weighing station, the conveying mechanism 1 can continue to operate to ensure that the sampling process does not affect the overall capacity of the system.

[0048] In this embodiment, as Figure 7 and Figure 9 As shown, the weighing device 7 also includes a bottle placement platform 75 located on one side of the weighing bottle holder 71. The transfer device 8 first transfers the irregularly shaped bottles to the bottle placement platform 75, and then places them one by one onto the weighing device 7 for weighing. In this way, only one weighing device 7 is needed to weigh all the irregularly shaped bottles, reducing the cost of setting up multiple weighing devices 7. The weighing device 7 is expensive, and the more devices there are, the higher the cost.

[0049] In this embodiment, as Figure 6 As shown, the filling station 3 is equipped with a lifting frame 31 and a second lifting drive for driving the lifting frame 31 to rise and fall. The lifting frame 31 is equipped with a row of filling needles 32. After the bottle holder 6 transports the irregularly shaped bottle to the filling station 3, the second lifting drive drives the lifting frame 31 to fall, so that the filling needles 32 are inserted into the irregularly shaped bottle below for filling. After filling is completed, the second lifting drive drives the lifting frame 31 to rise again, pulling the filling needles 32 out of the irregularly shaped bottle.

[0050] The distance between the front weighing station 2 and the rear weighing station 4 is at least three bottle holders 6, or the length of the filling station 3 is at least three bottle holders 6.

[0051] In this embodiment, the lifting frame 31 is provided with a row of inflation needles 33 in front of and / or behind the filling needle 32. Specifically, the inflation needles 33 are nitrogen filling needles. The lifting frame 31 moves up and down together with the inflation needles 33 and the filling needle 32. When the inflation needles 33 and the filling needle 32 reach below the bottle mouth, nitrogen is filled into the irregularly shaped bottle and the bottle is filled, respectively. Nitrogen can be filled before and after filling to control the residual oxygen content in the irregularly shaped bottle.

[0052] In this embodiment, downstream of the capping station 5, the conveying mechanism 1 has a capping inspection and rejection station 11 and a bottle exit station 12 arranged sequentially along the conveying direction of the conveying mechanism 1. After capping is completed, the conveying mechanism 1 transports the defective bottles to the capping inspection and rejection station 11 for inspection. If the capping is qualified, the bottles are output through the bottle exit station 12; if the capping is unqualified, they are rejected.

[0053] In this embodiment, the conveying mechanism 1 is provided with a positive / negative bottle detection station 13 upstream of the previous weighing station 2. The positive / negative bottle detection station 13 is used to detect the placement status of irregularly shaped bottles. If it is positive, the conveying mechanism 1 continues to convey it downwards; if it is negative, it is rejected.

[0054] In this embodiment, the front weighing station 2 and the rear weighing station 4 correspond to one weighing device 7. That is, the pre-filling weighing and the post-filling weighing are both completed on one weighing device 7, saving the number of weighing devices 7 and further reducing costs. In addition, the transfer device 8 rotates the irregularly shaped bottles at the two stations of front weighing station 2 and rear weighing station 4, increasing the utilization efficiency of the device and making the entire system structure more compact.

[0055] Example 2:

[0056] Figure 10 This invention illustrates an embodiment of the irregular-shaped bottle filling production method. The irregular-shaped bottle filling production method uses the irregular-shaped bottle filling production system of Embodiment 1 and includes the following steps:

[0057] S1. Bottle placement: Each bottle holder has 6 intermittent bottle placements;

[0058] S2, Front Weighing: The (2n-1)th bottle holder 6 transports the (2n-1)th group of irregularly shaped bottles to the front weighing station 2. The transfer device 8 transfers the (2n-1)th group of irregularly shaped bottles on the front weighing station 2 to the weighing device 7 for empty bottle weighing. After weighing, the transfer device 8 transfers the (2n-1)th group of irregularly shaped bottles on the weighing device 7 to the (2n)th bottle holder 6.

[0059] S3, Filling: The 2nth bottle holder 6 transports the 2n-1th group of irregularly shaped bottles to the filling station 3 for filling;

[0060] S4. Post-weighing: The 2nth bottle holder 6 transports the 2n-1th group of irregularly shaped bottles to the post-weighing station 4. The transfer device 8 transfers the 2n-1th group of irregularly shaped bottles on the post-weighing station 4 to the weighing device 7 for full-bottle weighing. After weighing, the transfer device 8 transfers the 2n-1th group of irregularly shaped bottles on the weighing device 7 to the 2n+1th bottle holder 6.

[0061] S5. Capping: The (2n+1)th bottle holder 6 transports the (2n-1)th group of irregularly shaped bottles to the capping station 5 for capping; n is a positive integer.

[0062] For example, firstly, bottles are intermittently placed in each bottle holder 6 (the bottle holders 6 are numbered S1, S2, S3, S4, S5, S6, S7, S8, S9, S10, S11, S12... from front to back; irregularly shaped bottles are numbered Z1, Z2, Z3, Z4, Z5, Z6... in group order; at the bottle placement station upstream of the weighing station 2, Z1 is placed on S1, Z2 on S3, Z3 on S5, Z4 on S7, Z5 on S9, Z6 on S11...); secondly, the first bottle holder 6 ( Figure 10 The first set of irregularly shaped bottles (with the designation S1) Figure 10 The material with the designation Z1 is conveyed to the front weighing station 2 (e.g., Figure 10As shown in the first row P1), the transfer device 8 will transfer the first group of irregularly shaped bottles from the front weighing station 2 (as shown in the first row P1). Figure 10 The first set of irregularly shaped bottles (numbered Z1) are transferred to the weighing device 7 for empty bottle weighing. After weighing, the transfer device 8 transfers the first set of irregularly shaped bottles from the weighing device 7 to the second bottle holder 6 (the second bottle holder 6 is located in...). Figure 10 If the standard number is S2, then, as Figure 10 As shown in the second row, P2, the second bottle holder 6 is located at the front weighing station 2; then, the second bottle holder 6 transports the first group of irregularly shaped bottles to the filling station 3 for filling (as shown in the image). Figure 10 (As shown in the third row P3, fourth row P4, and fifth row P5); then, the second bottle holder 6 transports the first group of irregularly shaped bottles to the rear weighing station 4 (as shown in the image). Figure 10 (As shown in page 6 of the middle section), the transfer device 8 transfers the first group of irregularly shaped bottles from the rear weighing station 4 to the weighing device 7 for full-bottle weighing. After weighing, the transfer device 8 transfers the first group of irregularly shaped bottles from the weighing device 7 to the third bottle holder 6 (the third bottle holder 6 is located in...). Figure 10 If the standard number is S3, then, as Figure 10 As shown on page 7 of the middle section, the third bottle holder 6 is located at the rear weighing station 4; then, the third bottle holder 6 transports the first group of irregularly shaped bottles to the capping station 5 for capping (as shown in the image). Figure 10 (As shown in row 8, page 8) After the capping is completed, the third bottle holder 6 will continue to transport the first group of irregularly shaped bottles backward (as shown in row 8, page ... Figure 10 (See page 9 of the middle row).

[0063] In this method for filling irregularly shaped bottles, the conveying mechanism 1 maintains intermittent, predetermined conveying time, advancing the distance of one bottle holder 6 each time. The conveying and bottle placement are matched; that is, bottles are placed intermittently on each bottle holder 6, meaning a bottle is placed on one holder 6 before a bottle is placed on the next. This allows the actions of each station to be matched with the conveying mechanism 1, enabling the conveying mechanism 1 to pause simultaneously at each station and all stations to operate simultaneously. This reduces the total downtime of the conveying mechanism 1, increases work efficiency, and lowers production costs. This method for filling irregularly shaped bottles features short total downtime, high work efficiency, and low production costs.

Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
