Description

Technical Field

[0001] The invention relates to the technical field of filling, and in particular to a double-bin vacuum liquid filling process production line and a filling process. Background Art

[0002] like Figure 1 and Figure 2 As shown, the double-chamber vacuum liquid packaging bottle 1 includes an inner bottle assembly 11, an outer bottle 14, a pump head assembly 12, a sealing pad 13 and an outer cover 15. The inner bottle assembly 11 is filled with a first liquid, and the pump head assembly 12 is filled with a second liquid. The pump head assembly 12 is clamped to the upper opening of the inner bottle assembly 11, and the outer bottle 14 is rotatably sleeved on the outer side of the inner bottle assembly 11. The outer cover 15 is clamped to the upper part of the pump head assembly 12. The inner bottle assembly 11 is made of transparent material, and the outer bottle 14 is made of non-transparent material to prevent the first liquid from being exposed to direct sunlight. The outer bottle 14 has a waist-shaped hole 141 extending along the generatrix, and the waist-shaped hole 141 is used to see the liquid level in the inner bottle assembly 11. When the pump head assembly 12 is pressed, a part of the second liquid is mixed with a part of the first liquid and squeezed out from the upper outlet of the pump head assembly 12. In the past, the filling of the first liquid in the inner bottle assembly 11 and the filling of the second liquid in the pump head assembly 12 in this packaging bottle were completed in two production lines. The filled pump head assembly 12 was assembled with the sealing pressure pad 13 and then transported to the filling line outlet in the inner bottle assembly 11, and then assembled with the outer bottle 14 and the outer cover 15 to form a double-compartment vacuum liquid packaging bottle 1.

[0003] The filling production lines on the market are mainly single-bin filling. For example, Chinese patent CN104276536B discloses a double-track liquid filling and capping machine. The double tracks here refer to the track for the packaging bottle and the track for the bottle cap. The entire device is essentially still a single-bin packaging bottle. Therefore, in the past, there would be an independent production line to fill the second liquid into the inner bottle component 11 and cover it with a sealing pressure pad 13 to form a first assembly 1a, and then another independent production line would fill the inner bottle component 11 with the first liquid, and then assemble the first assembly 1a and the inner bottle component 11 into a second assembly 1b, and the second assembly 1b would continue to be assembled with the outer bottle 14 into a third assembly 1c, and finally assembled with the outer cover 15 to obtain a double-bin vacuum liquid packaging bottle 1.

[0004] However, during the filling operation, the time the liquid is exposed to the air should be minimized, otherwise there is a greater risk of impurity contamination or moisture, which invisibly reduces the shelf life of the cosmetics. There is also a greater risk of falling during transportation.

[0005] Therefore, it is necessary to improve the production line structure to solve the above problems. Summary of the invention

[0042] The present invention is further described in detail below with reference to specific embodiments.

[0043] Example:

[0044] like Figures 1 to 3 As shown, a double-bin vacuum liquid filling process production line 2 of the present invention is used to fill a double-bin vacuum liquid packaging bottle 1. The double-bin vacuum liquid packaging bottle 1 includes an inner bottle assembly 11, a pump head assembly 12, a sealing pad 13, an outer bottle 14 and an outer cover 15. The inner bottle assembly 11 is filled with a first liquid, the lower part of the pump head assembly 12 is filled with a second liquid and is sealed with the sealing pad 13. The lower part of the pump head assembly 12 is clamped to the upper opening of the inner bottle assembly 11, the outer bottle 14 is rotatably sleeved on the outer side of the inner bottle assembly 11, and the outer cover 15 is clamped to the upper part of the pump head assembly 12.

[0045] like Figure 1 and Figure 2As shown, the double-bin vacuum liquid filling process production line 2 includes a first cup tray flow line 21a, an upper inner bottle mechanism 22, an inner bottle cleaning machine 23, an inner bottle filling machine 24, a pump head bottling machine 25, a pump head filling unit 26, a second cup tray flow line 21b, a visual recognition machine 27, an outer bottle loading station 28 and an upper outer cover mechanism 29. The upper inner bottle mechanism 22, the inner bottle cleaning machine 23, the inner bottle filling machine 24, the pump head bottling machine 25, the visual recognition machine 27 and the upper outer cover mechanism 29 are sequentially arranged on the first cup tray flow line 21a, the inlet and the outlet of the pump head filling unit 26 are butted with the first and last ends of the second cup tray flow line 21b, a section of the second cup tray flow line 21b is parallel to a section of the first cup tray flow line 21a and both pass through the lower part of the pump head bottling machine 25, and the end of the first cup tray flow line 21a is connected back to the feeding side of the upper inner bottle mechanism 22.

[0046] The first cup holder streamline 21a is used to circulate and transport the bottle cup holder 3a. The bottle cup holder 3a has a nearly rotating body structure with a large inner diameter at the upper part and a small inner diameter at the lower part, which can accommodate the positioning of the inner bottle assembly 11 and the outer bottle 14. The inner bottle assembly 11 is composed of an inner bottle and a bottle plug. The bottom of the inner bottle is provided with a vent hole, and the lower part of the bottle cup holder 3a has a positioning ejector matching the vent hole. The upper inner bottle mechanism 22 is used to place the inner bottle assembly 11 with the opening facing upward on the bottle cup holder 3a, and appropriately rotate the inner bottle assembly 11 so that its angle is limited by the positioning ejector (the relevant technology has applied for patent CN221606483U, a bottle plug limit buffer and bottle body positioning cup holder). The bottle cup holder 3a can also position the outer bottle 14 by an indefinite angle at the upper part. The inner bottle cleaning machine 23 is located on the feeding side of the inner bottle filling machine 24, and is used to blow and clean the inside of the inner bottle assembly 11. The inner bottle filling machine 24 fills the first liquid material quantitatively into the inner bottle assembly 11. The second cup holder flow line 21b and the pump head filling unit 26 circulate and convey the pump head cup holder 3b. The pump head cup holder 3b can position the pump head assembly 12 facing upward. The pump head filling unit 26 fills the pump head assembly 12 with the second material and installs the sealing pad 13. During this process, the pump head assembly 12 faces upward. The pump head bottling machine 25 is used to clamp the first assembly 1a onto the filled inner bottle assembly 11 to form the second assembly 1b. The visual recognition machine 27 is used to perform visual inspection on the inner bottle assembly 11 (Chinese patent 2023231548267 has been applied for a multi-angle identification device for foreign matter in a bottle), so that the defective inner bottle assembly 11 and foreign matter in the first liquid are screened out, and the second assembly 1b without foreign matter continues to be transported backward. At the outer bottle installation station 28, the outer bottle 14 can be installed manually or automatically under the second assembly 1b, and then rotated appropriately to tighten the second assembly 1b and the outer bottle 14 to form a third assembly 1c. The upper outer cover mechanism 29 is used to assemble the outer cover 15 to the third assembly 1c to obtain a double-compartment vacuum liquid packaging bottle 1 (Chinese patent CN208603679U has been applied for an automatic outer cover device for cream products).

[0047] like Figure 4 and Figure 5 As shown, the pump head bottling machine 25 comprises a pump head conveying device 251 spanning over the first cup tray streamline 21a and the second cup tray streamline 21b, a pump head flipping and pressing device 252 located above the second cup tray streamline 21b, a pump head in-position sensor 253a located on the side of the second cup tray streamline 21b, an inner bottle in-position sensor 253b located on the side of the first cup tray streamline 21a, and a bottle body clamping mechanism 254 located on both sides of the first cup tray streamline 21a. In the pump head bottling machine 25, the first cup tray streamline 21a and the second cup tray streamline 21b are transported along a first horizontal direction. The pump head transfer device 251 includes a translation module 2511, a lifting module 2512 driven by the translation module 2511 to move along the second horizontal direction, a plurality of pump taking telescopic cylinders 2513 driven to lift and lower by the lifting module 2512, and a pump taking suction and release head 2514 driven and extended vertically by each pump taking telescopic cylinder 2513. The pump head flipping and pressing device 252 includes a rotary module 2521, a plurality of bottling telescopic cylinders 2522 driven to rotate around the first horizontal direction by the rotary module 2521, and a plurality of bottling suction and release heads 2523 driven and extended radially by each bottling telescopic cylinder 2522. The number of the pump taking suction and release heads 2514 is equal to the number of the bottling suction and release heads 2523. All the pump taking suction and release heads 2514 are arranged side by side along the first horizontal direction, and all the bottling suction and release heads 2523 are arranged side by side along the first horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction. The translation module 2511 is higher than the pump head flipping and pressing device 252. When the pump head position sensor 253a detects the pump head cup holder 3b and the inner bottle position sensor 253b detects the bottle body cup holder 3a, it outputs a signal to allow the bottle body clamping mechanism 254 to clamp and position the inner bottle assembly 11 from both sides.

[0048] The first assembly 1a formed by the pump head assembly 12 and the sealing pressure pad 13 is transported to the pump head bottling machine 25 along the second cup tray streamline 21b under the support of the pump head cup tray 3b, and the pump head in-position sensor 253a confirms that a row of first assemblies 1a are in position; the inner bottle assembly 11 after filling is transported to the pump head bottling machine 25 along the first cup tray streamline 21a under the support of the bottle body cup tray 3a, and the inner bottle in-position sensor 253b confirms that a row of inner bottle assemblies 11 are in position, and the bottle body clamping mechanism 254 clamps and positions the row of inner bottle assemblies 11; the pump head transfer device 251 uses the extended pump taking and suction head 2514 to suck up the row of first assemblies 1a in position, and the pump taking telescopic cylinder 2513 makes the pump taking and suction cylinder 2513 suck up the first assemblies 1a in position. The head 2514 retracts slightly, and the lifting module 2512 raises the movable first assembly 1a to a height higher than the pump head flipping and pressing device 252, and then moves horizontally to the top of the pump head flipping and pressing device 252; the pump head flipping and pressing device 252 uses the extended bottling suction and release head 2523 to suck up this row of first assemblies 1a, and the pump suction and release head 2514 breaks the vacuum. The bottling telescopic cylinder 2522 causes the bottling suction and release head 2523 to retract slightly, and the rotating module 2521 causes the first assembly 1a to flip 180° up and down, and then the bottling telescopic cylinder 2522 causes the bottling suction and release head 2523 to extend again, so that the positive first assembly 1a is pressed onto the inner bottle component 11 that has been positioned, and the bottling is completed.

[0049] like Figure 6 As shown, the pump head filling unit 26 includes a circulation indexing plate 261, a first vibrating feeder 262, an upper pump head mechanism 263, a pump head filling mechanism 264, a second vibrating feeder 265, an upper pressure pad mechanism 266, a press-fitting mechanism 267 and an ejection mechanism 268. Notches for accommodating the pump head cup holder 3b are evenly distributed around the circulation indexing plate 261. The outlet of the second cup holder flow line 21b, the upper pump head mechanism 263, the pump head filling mechanism 264, the upper pressure pad mechanism 266, the press-fitting mechanism 267 and the inlet of the second cup holder flow line 21b are sequentially distributed on the outer periphery of the circulation indexing plate 261. The outlet of the first vibrating feeder 262 is connected to the upper pump head mechanism 263, the outlet of the second vibrating feeder 265 is connected to the upper pressure pad mechanism 266, and the ejection mechanism 268 is located at a relative position of the entry direction of the second cup holder flow line 21b.

[0050] The rotating indexing plate 261 is used to position the pump head cup holder 3b at the notch and move it stepwise. The first vibrating feeder 262 is used to supply the pump head assembly 12 to the upper pump head mechanism 263, and the upper pump head mechanism 263 places the pump head assembly 12 on the pump head cup holder 3b with the reverse side facing upward. The pump head filling mechanism 264 fills the pump head assembly 12 with the second liquid. The second vibrating feeder 265 is used to supply the sealing pad 13 to the upper pad mechanism 266, and the pressing mechanism 267 is used to press the sealing pad 13 on the reverse side of the pump head assembly 12, thereby forming the first assembly 1a. The ejection mechanism 268 ejects the pump head cup holder 3b carrying the first assembly 1a to the entrance of the second cup holder flow line 21b.

[0051] The working process of this double-bin vacuum liquid filling process production line 2 is as follows:

[0052] S1. Place inner bottle: the inner bottle placing mechanism 22 places the inner bottle assemblies 11 one by one on the bottle cup holder 3a located on the first cup holder streamline 21a. There is a certain relative angle between the inner bottle assembly 11 and the bottle cup holder 3a, and there is also a certain positional relationship between the bottle cup holder 3a and the first cup holder streamline 21a.

[0053] S2, first liquid filling: the inner bottle assembly 11 first passes through the inner bottle cleaning machine 23 for dust removal by air blowing, and then passes through the inner bottle filling machine 24 for filling with the first liquid. The filled inner bottle assembly 11 continues to enter the pump head bottling machine 25 along the first cup holder flow line 21a.

[0054] S3, filling of the second liquid: the first vibrating feeder 262 transports the reverse pump head assembly 12 to the upper pump head mechanism 263 one by one, the upper pump head mechanism 263 places the pump head assembly 12 on the pump head cup holder 3b brought by the circulating indexing plate 261, the circulating indexing plate 261 makes the pump head cup holder 3b move step by step, so that the pump head assembly 12 completes the filling of the second liquid under the pump head filling mechanism 264, and then reaches the upper pressure pad mechanism 266, at which time the upper pressure pad mechanism 266 places the sealing pressure pad 13 sent by the second vibrating feeder 265 on the reverse side of the pump head assembly 12, the pressing mechanism 267 presses the sealing pressure pad 13 and the pump head assembly 12 into one, forming a first assembly 1a, the first assembly 1a reaches the outlet of the circulating indexing plate 261 and is pushed out by the pushing mechanism 268 onto the second cup holder flow line 21b.

[0055] S4, assembly: the bottle cup holder 3a carrying the inner bottle assembly 11 is pressed against the inner bottle in place sensor 253b when entering the pump head bottling machine 25, and the bottle clamping mechanism 254 fixes the inner bottle assembly 11, and at the same time, the pump head cup holder 3b carrying the first assembly 1a is arranged in a row and transported along the second cup holder streamline 21b, and is pressed against the inner bottle assembly 11 when entering the pump head bottling machine 25, and is then sensed by the pump head in place sensor 253a, at which time the pump head conveying device 251 and the pump head flipping and pressing device 252 cooperate to remove a row of first assemblies 1a from the pump head cup holder 3b, flip them 180° forward and backward, and then install them in the upper opening of the inner bottle assembly 11 to form a second assembly 1b, and the second cup holder streamline 21b moves the second assemblies 1b out of the pump head bottling machine 25 in batches.

[0056] S5, visual recognition: the visual recognition machine 27 performs visual inspection on the second assembly 1b. Specifically, the position of the bottle cup holder 3a is fixed first, the second assembly 1b is clamped from the bottle cup holder 3a, and the lower part of the second assembly 1b with transparent outer side is photographed. If the image of the second assembly 1b has defects and foreign matter, the second assembly 1b is removed. If there is no abnormality, the second assembly 1b is put back into the bottle cup holder 3a.

[0057] S6. Installing outer bottle: When the second assembly 1b passes through the outer bottle installing station 28, the outer bottle 14 is installed at the lower part of the second assembly 1b, and the outer bottle 14 is rotated appropriately so that the second assembly 1b and the outer bottle 14 are stuck to form a third assembly 1c.

[0058] S7, installing outer cover: When the third assembly 1c passes through the upper outer cover mechanism 29, the upper outer cover mechanism 29 installs the outer cover 15 on the upper part of the third assembly 1c to form a double-compartment vacuum type liquid packaging bottle 1, and the vacated bottle cup holder 3a is sent back to the upper inner bottle mechanism 22 to load a new bottle.

[0059] The above production line can automatically and continuously complete the filling of the inner bottle assembly 11, the filling of the pump head assembly 12, the assembly of the double-compartment vacuum type liquid packaging bottle 1 and the boxing of the double-compartment vacuum type liquid packaging bottle 1. The equipment has a compact structure and makes rational use of the on-site space. The entire process involves fewer personnel, which reduces personnel costs and the probability of handling accidents. It reduces the time that the liquid is exposed to air pollution and moisture, and ensures the shelf life of the cosmetics. There are inspections after important steps to avoid unqualified products leaving the factory.

[0060] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
