Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly relates to a filling and boxing production line for cream products. Background Art

[0002] The packaging of some cream cosmetics requires multiple steps. The first step is to pour the product into the cosmetic bottle from top to bottom. The second step is to put the cosmetic bottle into the inner lining. The third step is to put the inner lining into the packaging box. The difficulty lies in controlling the posture of the cosmetic bottle. As Figure 1 shown, the packaging bottle 1 includes a bottle body 11, a pump head 12 installed in the bottle mouth of the bottle body 11, an inner ring 13 of the pump head arranged above the bottle body 11, a discharge nozzle 14 arranged at the top of the pump head 12, and an outer cover 15 sleeved outside the inner ring 13 of the pump head. The overall shape of this packaging bottle 1 is approximately ellipsoidal, and the lower bottle body 11 is an arc surface structure, which cannot be stably placed on a plane while keeping the opening upward by itself. There are two directions for the stable placement of the packaging bottle 1. The direction towards which the discharge nozzle 14 faces is the front, and the opposite side is the back. The production date needs to be marked on the back of the packaging bottle 1. Therefore, a front mark 111 is provided on the front of the bottle body 11. When the filling and assembly of the packaging bottle 1 are completed, the fronts need to be in the same direction so that the production date information can be marked on the back of the packaging bottle 1.

[0003] The Chinese patent CN216154213U applied by our company discloses an automatic packaging line for cream products. This equipment can automatically complete the processes of putting the bottle on, putting the inner plug, filling, inkjet coding, screwing the cap, and boxing for cream products. Here, the lower part of the packaging bottle of the cream product is cylindrical, and the relative angle during transportation with the cup holder is positioned by other means, which is not applicable to the occasion with the characteristics of the upper bottle body 1.

[0004] Therefore, it is necessary to design a new packaging device to solve the above problems. Summary of the Invention

[0036] The following further elaborates on the present utility model in conjunction with specific embodiments.

[0037] Embodiment:

[0038] As Figure 2 shown, a filling and cartoning production line 2 for cream products of the present utility model includes a filling unit 21, a transfer unit 22, a lining placing unit 23, and a cartoning unit 24 arranged in sequence. The filling unit 21 injects the cream product into the bottle body 11 and completes the assembly of the packaging bottle 1. The transfer unit 22 turns the packaging bottle 1 into a horizontal state and sends it into the lining placing unit 23. The lining placing unit 23 installs the packaging bottle 1 into the lining, and the cartoning unit 24 installs the lining into the packaging box.

[0039] As Figure 3 shown, the filling unit 21 includes a rotary disk 211. A plurality of limiting notches 2111 are evenly distributed around the edge of the rotary disk 211. An inlet feeding station 21a, an empty bottle cleaning station 21b, a positive and negative detection station 21c, a filling station 21d, an upper pump head station 21e, a screwing station 21f, an installation and discharging station 21g, an installation and recycling station 21h, a discharging nozzle installation station 21i, a bottle installation detection station 21j, a rejected product exclusion station 21k, and a discharging station 21l are successively arranged around the rotary disk 211. The bottle body 11 is placed on the cup holder 3 with the bottle mouth facing upward. The limiting notches 2111 accommodate the cup holder 3 so that it passes through the above stations in sequence.

[0040] With the positioning of the bottle body 11 by means of the cup holder 3, the rotary disk 211 can conveniently feed, process, and discharge the bottle body 11 in sequence and complete their respective tasks at each station.

[0041] As Figures 2 to 4As shown in the figure, the inner lining placing unit 23 includes a horizontal conveyor line 231 and a marking mechanism 232 located above the horizontal conveyor line 231. The marking mechanism 232 marks the reverse side of the packaging bottle 1. The transfer unit 22 includes a feeding line 221 extending from the feeding port of the inner lining placing unit 23 to the feeding station 21a, a discharging line 222 extending from the discharging station 21k to one side of the horizontal conveyor line 231, and a packaging bottle removing mechanism 223 located between the discharging line 222 and the horizontal conveyor line 231. The end of the discharging line 222 is connected to the head end of the feeding line 221. Inside the feeding station 21a, there is a first cup holder yielding mechanism 219a, and inside the material returning station 21h, there is a first cup holder pushing mechanism 219b.

[0042] The feeding line 221 is used to send the empty cup holders 3 back to the feeding station 21a. During the conveying process, the operator is responsible for placing the empty bottle bodies 11 onto the cup holders 3. The discharging line 222 is used to send the packaged bottles 1 together with the cup holders 3 that have been filled to the inner lining placing unit 23. During the conveying process, the outer caps 15 are manually installed. When the cup holder 3 reaches the feeding port of the inner lining placing unit 23, the packaging bottle 1 is moved by the packaging bottle removing mechanism 223 onto the horizontal conveyor line 231, and its vertical state is changed to a horizontal state. Then, the marking mechanism 232 marks the production date on the reverse side of the packaging bottle 1. Subsequently, after the inner lining placing unit 23 places the inner lining into the packaging bottle 1, it reaches the boxing unit 24 to complete boxing. Only when the empty limit notch 2111 aligns with the outlet of the discharging line 222, the first cup holder yielding mechanism 219a will allow the cup holder 3 to enter the feeding station 21a. Only when the limit notch 2111 aligns with the inlet of the discharging line 222, the second cup holder pushing mechanism 219b will push the cup holder 3 away from the discharging station 21l. Both the first cup holder yielding mechanism 219a and the second cup holder pushing mechanism 219b complete the transfer of the cup holder 3 by telescopic movement. Only when the limit notch 2111 pauses at each station, the first cup holder yielding mechanism 219a and the second cup holder pushing mechanism 219b will have telescopic movement.

[0043] As Figure 5 shown in the figure, above the empty bottle cleaning station 21b, there is an empty bottle cleaning mechanism 212. The empty bottle cleaning mechanism 212 has a nozzle 2121 that blows air into the bottle mouth and an inverted sensor 2122 that detects whether the nozzle 2121 is lifted by the bottle body 11. When the inverted sensor 2122 senses that the nozzle 2121 rises, it will cause the turntable 211 to stop and alarm.

[0044] The nozzle 2121 has a nested structure of inner and outer tubes. When it extends into the bottle body 11, the middle tube blows air and the outer tube sucks air, so as to blow the impurities in the bottle and immediately suck them away. Therefore, the nozzle 2121 has a lifting function. Ideally, when the bottle body 11 is placed upright on the cup holder 3 with the bottle mouth upward, the nozzle 2121 will not touch the bottle body 11 and the nozzle 2121 can work properly. However, in an accident, the bottle body 11 may be placed upside down on the cup holder 3, and its tail will hinder the descent of the nozzle 2121. At this time, the nozzle 2121 cannot achieve the cleaning effect. To avoid this problem, the inversion sensor 2122 will predict that the state of the bottle body 11 is incorrect. At this time, the production line will pause and remind the worker to place the bottle body 11 upright.

[0045] As Figure 5 shown, a first vision detection mechanism 2131a and a first lighting mechanism 2132a are provided outside the front and back detection station 21c. The first vision detection mechanism 2131a detects the front mark 111 on the bottle body 11 from the horizontal direction, and the first lighting mechanism 2132a lights up the preset position of the front mark 111 from the lower oblique direction.

[0046] If the front and back positions of the bottle body 11 are correct, the first vision detection mechanism 2131a can normally detect the front mark 111. Otherwise, it means that the bottle body 11 is reversed front and back and needs to be flipped front and back. The first lighting mechanism 2132a can provide surface light to illuminate the position where the front mark 111 is located, preventing the ambient light from affecting the accuracy of the judgment of the first vision detection mechanism 2131a.

[0047] As Figure 5 shown, a filling mechanism 2141 is provided above the filling station 21d. The cup holder 3 includes a base 31 and a support 32. The support 32 supports the lower part of the bottle body 11. The base 31 is an annular structure that is penetrated up and down. The lower part of the support 32 passes through the middle of the support 32 and a bottom surface gear 321 is provided at the bottom. The support 32 can be located on the base 31 at two positions of 180°. An adjustment mechanism 2142 for jacking up and rotating the support 32 by 180° is provided below the filling station 21d. The adjustment mechanism 2142 has a surface gear that cooperates with the bottom surface gear 321.

[0048] If the first visual inspection mechanism 2131 detects the front mark 111, it indicates that the posture of the bottle body 11 is correct. At this time, the filling mechanism 2141 can directly perform filling; otherwise, the adjustment mechanism 2142 will rotate the support 32 by 180°. At this time, the position of the bottle body 11 will be correct, and then filling will start. The adjustment mechanism 2142 is arranged at the filling station 21d because the bottle body 11 will stay in place during filling, and the adjustment mechanism 216 rotating the bottle body 11 does not affect the filling process, so the station can be saved and the equipment structure can be made more compact. After completing the front and back adjustment, it can be ensured that the packaging bottle 1 passes under the marking mechanism 232 in the same posture, that is, the back of the packaging bottle 1 faces the marking mechanism 232, so that correct marking can be carried out.

[0049] As Figure 4 shown, a pump head feeding assembly 215 is provided outside the upper pump head station 21e. The pump head feeding assembly 215 includes a pump head vibrating pan 2151, a pump head conveying line 2152 extending from the outlet of the pump head vibrating pan 2151 to the upper pump head station 21e, and a pump head transfer mechanism 2153 that transfers the pump head 12 from the end of the pump head conveying line 2152 to the bottle mouth of the bottle body 11 located at the upper pump head station 21e. The pump head transfer mechanism 2153 has a pre-rotation function; a tightening mechanism 216 is provided above the tightening station 21f.

[0050] The pump heads 12 can be automatically vertically arranged under the action of the pump head vibrating pan 2151, and then lined up by the pump head conveying line 2152 and sent to the upper pump head station 21e one by one. The pump head transfer mechanism 2153 will place the pump head 12 above the bottle body 11 that has completed filling and rotate it preliminarily to prevent the pump head 12 from falling or being knocked crooked. Subsequently, the tightening of the pump head 12 is completed by the tightening mechanism 216.

[0051] As Figure 3 shown, an artificial assembly line 217 is provided on the side of the rotary table 211. The inlet of the artificial assembly line 217 is butt-connected to the installation discharge station 21g, and the outlet is butt-connected to the installation return station 21h. A second cup holder pushing mechanism 219c is provided inside the installation discharge station 21g, and a second cup holder yielding mechanism 219d is provided inside the installation return station 21h.

[0052] The manual assembly line 217 enables the cup holder 3 to temporarily leave the limit notch 2111, and the assembly of the inner ring of the pump head is completed manually. Only when the limit notch 2111 aligns with the entrance of the manual assembly line 217, the second cup holder pushing mechanism 219c will push the cup holder 3 away from the installation feeding station 21h. Only when the empty limit notch 2111 aligns with the exit of the manual assembly line 217, the second cup holder yielding mechanism 219d will allow the cup holder 3 to enter the installation discharging station 21g. Both the second cup holder pushing mechanism 219c and the second cup holder yielding mechanism 219d complete the transfer of the cup holder 3 by telescopic movement. Only when the limit notch 2111 pauses at each station, the second cup holder pushing mechanism 219c and the second cup holder yielding mechanism 219d will have telescopic movement.

[0053] Outside the bottle filling and discharging nozzle station 21i, there is a feeding and discharging nozzle assembly 218. The feeding and discharging nozzle assembly 218 includes a discharging nozzle vibrating pan 2181, a discharging nozzle conveyor line 2182 extending from the outlet of the discharging nozzle vibrating pan 2181 to the bottle filling and discharging nozzle station 21i, and a discharging nozzle mounting mechanism 2183 that transfers the discharging nozzle 15 from the end of the discharging nozzle conveyor line 2182 and presses it onto the bottle body 11 located at the bottle filling and discharging nozzle station 21i.

[0054] The discharging nozzle vibrating pan 2181 realizes the automatic arrangement of the discharging nozzles 14, the discharging nozzle conveyor line 2182 realizes the conveying of the discharging nozzles 14, and the discharging nozzle mounting mechanism 2183 completes the pressing of the discharging nozzles 14, achieving automated assembly.

[0055] Outside the bottle filling inspection station 21j, there is a second vision inspection mechanism 2131b and a second lighting mechanism 2132b. The second vision inspection mechanism 2131b detects the state of the packaging bottle 1 in the horizontal direction, and the second lighting mechanism 2132b shines light on the packaging bottle 1 from the lower oblique direction; inside the defective product removal station 21k, there is a third cup holder pushing mechanism 219e that pushes the cup holder 3 away from the limit notch 2111, and there is a defective product output channel 25 in the pushing direction of the third cup holder pushing mechanism 219e.

[0056] To avoid shipping defective products, before the packaging bottle 1 undergoes the next packaging step, it is necessary to use the second vision inspection mechanism 2131b for appearance inspection. Only qualified products can reach the discharging station 21k, and unqualified products are pushed out together with the cup holder 3 by the third cup holder pushing mechanism 219e to the defective product output channel 25 at the defective product removal station 21k. The second lighting mechanism 2132b can provide surface light to illuminate the packaging bottle 1 and prevent ambient light from affecting the accuracy of the judgment of the second vision inspection mechanism 2131b.

[0057] The working process of this production line is as follows: The empty cup holder 3 is conveyed through the feeding line 221, and the bottle body 11 is placed into the cup holder 3 manually without distinguishing the front and back; when the rotary disk 211 is changing positions, the first cup holder yielding mechanism 219a will first block the outside of the feeding station 21a to prevent the cup holder 3 from moving further. When the empty limit notch 2111 stays at the feeding station 21a, the first cup holder yielding mechanism 219a will retract inward, so that a cup holder 3 carrying the bottle body 11 enters the limit notch 2111 at the feeding station 21a; subsequently, the rotary disk 211 rotates with the cup holder 3 to the empty bottle cleaning station 21b. Generally, the bottle body 11 is always with the bottle mouth upward, so the nozzle 2121 can descend without being blocked, the sensor 2122 does not emit a signal, and the nozzle 2121 normally blows air into the bottle to complete the cleaning; if the bottle body 11 is placed upside down on the cup holder 3, the nozzle 2121 cannot descend, and the inverted sensor 2122 cannot sense that the nozzle 2121 is in the normal position. At this time, the machine will stop and remind the worker to troubleshoot the problem, and then the cleaning work will be carried out; the cleaned bottle body 11 moves to the front and back detection station 21c. With the assistance of the first lighting mechanism 2132a, the first vision detection mechanism 2131a will detect whether the front mark 111 of the bottle body 11 faces outward at this time. If the front mark 111 is detected, when the bottle body 11 moves to the filling station 21d, the adjustment mechanism 2142 will not take any action. Otherwise, the adjustment mechanism 2142 will rotate the supporting seat 32 by 180° by lifting it, so that the bottle body 11 will be turned over front and back accordingly. When ensuring the correct posture of the bottle body 11, the filling mechanism 2141 completes the filling of the cream product; subsequently, the filled bottle body 11 moves to the pump head installation station 21e, and the pump head transfer mechanism 2153 inserts the pump head 12 into the bottle mouth from top to bottom and pre-rotates it. Then, the bottle body 11 and the pump head 12 are conveyed to the screwing station 21f together, and then the screwing mechanism 216 screws the pump head 12 tightly; then when the cup holder 3 reaches the installation and discharging station 21g, it is pushed into the manual assembly line 217 by the second cup holder pushing mechanism 219c. The worker presses the inner ring 13 of the pump head above the pump head 12 to form an assembled body. Then, the cup holder 3 carrying the assembled body reaches before the installation and return station 21h; when the rotary disk 211 is changing positions, the second cup holder yielding mechanism 219d will first block the outside of the installation and return station 21h to prevent the cup holder 3 from moving further. When the empty limit notch 2111 stays at the installation and return station 21h, the second cup holder yielding mechanism 219d will retract inward, so that a cup holder 3 carrying the assembled body enters the limit notch 2111 at the installation and return station 21h; the assembled body is then taken to the discharging nozzle installation station 21i, and the discharging nozzle mechanism 2183 presses the discharging nozzle 14 above the assembled body to obtain the lidless packaged bottle;Then, the lidless packaging bottle 1 is taken to the bottling inspection station 21j. With the assistance of the second lighting mechanism 2132b, the second vision inspection mechanism 2131b inspects the appearance of the lidless packaging bottle to distinguish defective products from qualified products. When the cup holder 3 of the defective product reaches the defective product exclusion station 21k, it will be pushed by the third cup holder ejection mechanism 219e into the defective product output channel 25. The cup holder 3 of the qualified product continues to move to the discharging station 21l and is then pushed by the first cup holder ejection mechanism 219b onto the discharging line 222. The cup holders 3 of the qualified products are arranged on the discharging line 222, and then the outer lid 15 is manually installed to obtain the complete packaging bottle 1. The cup holder 2 moves forward with the packaging bottle 1 to the end of the discharging line 222. Then, the packaging bottle removal mechanism 223 picks up multiple packaging bottles 1 together. The packaging bottles 1 are rotated from the vertical posture to the horizontal posture and placed on the horizontal conveyor line 231. When it passes through the marking mechanism 232, the marking mechanism 232 marks the production date on the back of the packaging bottle 1. Then, the lining unit 23 pushes the packaging bottles 1 into the linings one by one. Finally, at the boxing unit 24, the linings containing the packaging bottles 1 are pushed into the packaging boxes, thus completing the packaging.;

[0058] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
