Description

Technical Field

[0001] The invention relates to the technical field of automated packaging, and in particular to a capping production line for bottled products. Background Art

[0002] In recent years, more and more high-end daily chemical products are packaged in colorful bottles, which greatly improves the packaging grade of the products and is more popular. Most high-end daily chemical products are packaged with pump covers, which is more convenient during use.

[0003] In the process of automated packaging, the pump cap needs to be screwed onto the threaded bottle. In this process, the pump cap needs to be transferred from one production line to the screwing station, and the bottle body needs to be transferred to the screwing station via the transmission line. Then, the pump cap is screwed onto the bottle body through the screwing equipment. After the screwing is completed, the entire bottle body is transferred to other production lines. How to transfer the pump cap to the bottle body transmission line position and how to screw the pump cap onto the bottle body stably without affecting the production efficiency of the overall production line are problems that need to be solved in the field of automated packaging.

[0004] Traditionally, pump covers are mostly transferred to the screwing station manually. Even if there are automated transfer equipment, the equipment structure is relatively complex, and it is difficult to achieve cyclic and orderly transfer of pump covers.

[0023] Beneficial Effects

[0024] 1. The present invention designs a circulating conveyor belt in the clamping and transmission component and the feeding clamping hand component. The circulating conveyor belt is used to separate the pump cover from the clamping and transmission component in sequence and transfer it to the position of the feeding clamping hand component, and then the feeding work is completed by the feeding clamping hand component. After the feeding is completed, the circulating conveyor belt of the bottle cap transfer component continues to circulate and transmit, and the receiving seat without the pump cover continues to move to the position of the clamping and transmission component for loading, that is to say, the loading, transmission and feeding of the pump cover can be realized at the same time, which greatly improves the work efficiency. During the screwing process of the screwing station, the pump cover clamping screwing component and the bottle body clamping component are controlled to realize the screwing operation of the pump cover. At the same time, the screwing work of the pump cover does not affect the previous pump cover loading, transmission and feeding work, which greatly improves the efficiency of the production line. And during the screwing process of the pump cover, the bottle body can be stabilized by the bottle body clamping head to ensure the stability of the bottle body during the screwing process.

[0025] 2. The present invention uses a pair of transmission chains to realize the transmission of the pump cover, and the spacing between the two transmission lines is just enough to clamp the pump cover and move it forward with the transmission chain. Left and right limit rods can also be set on the transmission chain to limit the left and right sides of the pump cover, so that the position of the pump cover is relatively fixed, which is convenient for loading the bottle cap transfer assembly. The purpose of the height limit rod is to limit the height of the pump cover to prevent multiple pump covers from overlapping during the transmission of the pump cover, which affects the subsequent loading operation. A spacing adjustment component is set on the side of the transmission chain to adjust the spacing between a pair of transmission chains so that it can adapt to different product pump cover sizes and is more practical.

[0026] 3. The present invention designs a vertical circulating conveyor belt, which is surrounded by an ellipse. The receiving seat is set on a vertical slide rail, and the height of the entire receiving seat can be slightly adjusted by the slide rail, which is convenient for docking with the clamping transmission component and the loading clamping hand component. A fixed baffle is set on the side of the circulating conveyor belt facing the clamping transmission component to block the receiving seat after loading. After the loading is completed, the receiving seat moves forward with the circulating conveyor belt. During the movement, the fixed baffle is blocked to prevent the pump cover from falling. At the loading position, the gap between adjacent fixed baffles is used for the loading operation of the pump cover. The purpose of the adjustable baffle in the present invention is that when the pump cover is loaded from the clamping transmission component to the circulating conveyor belt, it moves to the position of the loading clamping hand component under the drive of the circulating conveyor belt, and the adjustable baffle can play a shielding role. When the loading clamping hand component needs to clamp the pump cover for feeding, the adjustable baffle can be rotated to a certain angle, away from the receiving seat, without affecting the stroke of the loading clamping hand component clamping the pump cover. The first connecting rod is pulled by extending the telescopic cylinder. After the first connecting rod is pulled, the rotating plate rotates along the base of the circulating conveyor belt, so that the first connecting rod drives the adjustable baffle rod connected to it to rotate upward by a certain angle and leave the receiving seat of the circulating conveyor belt.

[0027] 4. The present invention sets a pump head direction adjustment channel in the arc area, and the width of the pump head direction adjustment channel is smaller than the length of the pump head of the pump cover and larger than the width of the pump head. In this way, when the pump cover enters the pump head direction adjustment channel, the pump nozzle of the pump cover faces in one direction due to the obstruction of the channel, which is convenient for the rear loading clamping assembly to grab and feed the material.

[0028] 5. The present invention arranges the clamping transmission component and the loading gripper component on a longitudinal sliding mechanism, which can move forward and backward to facilitate loading and feeding.

[0029] 6. The present invention arranges the pump cover clamping and screwing assembly and the bottle body clamping assembly on the first and second drive assemblies. During the screwing process at the screwing station, the pump cover clamping and screwing assembly and the bottle body clamping assembly are controlled to be transmitted along the transmission direction of the bottle body transmission line. In this way, the pump cover screwing operation can be achieved while non-stop transmission is performed, greatly improving the production line efficiency. In addition, during the screwing process of the pump cover, the bottle body can be stabilized by the bottle body clamping head to ensure the stability of the bottle body during the screwing process. The designed first drive assembly enables the clamping rotating head to move up and down and left and right through the first transverse slide rail and the first longitudinal slide rail. In this way, when screwing, the clamping rotating head can be controlled to move left and right at the same speed according to the transmission speed of the bottle body transmission line. The first longitudinal slide rail can control the height of the entire clamping rotating head, so that the clamping rotating head can adapt to different bottle body structures. The designed second driving assembly drives the entire bottle body clamping assembly to be transmitted along the transmission direction of the bottle body transmission line through the second transverse slide rail. Through the meshing of the rack and the gear, the second driving motor drives the gear to rotate on the rack, driving the connecting frame thereon to be transmitted along the direction of the bottle body transmission line. In this way, the bottle body clamping assembly connected with the first receiving plate and the second receiving plate can be driven to be transmitted as a whole in the direction of the bottle body transmission line.

[0030] 7. The clamping rotating head of the present invention is driven to rotate by the first driving motor, and the rotation of the first rotating shaft drives the pump cover clamping claw below it to rotate. The clamping operation of the pump cover clamping claw is realized by the up and down extension of the clamping cylinder to realize the up and down movement of the first rotating shaft. During the up and down extension process, the first clamping claw connecting seat drives the connecting piece on it to move up and down. Because of the rotation relationship between the two ends of the connecting piece, it drives the connected pump cover clamping claw to perform a clamping action, thereby realizing the operation of the pump cover clamping claw to clamp the pump cover.

[0031] 8. The second connecting rod of the present invention does not rotate with the first rotating shaft, so that during the overall rotation of the first rotating shaft, the clamping plate and the limiting rod at the end of the second connecting rod do not rotate, so that when the bottle cap with the pump head is screwed, the pump head can be limited. In order to ensure that the second connecting rod does not rotate with the first rotating shaft, a limiting notch is set in the sleeve shell at the end of the clamping cylinder, and the limiting column connected to the second connecting rod is directly inserted into the limiting notch. During the rotation of the first rotating shaft, the second connecting rod does not rotate with the outer first rotating shaft under the action of the limiting column, thereby realizing the limiting effect.

[0032] 9. The present invention arranges the first receiving plate and the second receiving plate on the second adjusting slide, and realizes the receiving plate sliding on the adjusting slide through the first adjusting slide rail, so as to slide toward or away from the bottle body transmission line, so as to adapt to the bottle body structure of different product sizes. When the bottle body size is small or large, the distance between the first receiving plate and the second receiving plate can be slightly adjusted by adjusting the slide.

[0033] 10. The present invention designs the first adjusting slide on the longitudinal adjusting mechanism, so that the height of the first receiving plate and the second receiving plate can be adjusted as a whole, and the height of the bottle body clamping cylinder can be further adjusted, which can adapt to the bottle body structure of products of different heights. When the bottle body is shorter or taller, the second rotating shaft is rotated by the hand wheel, and the lateral rotation is converted into the longitudinal rotation through the first bevel gear and the second bevel gear. In this way, the first adjusting slide can be adjusted by rotating the screw to achieve the height adjustment of the overall receiving plate.

[0034] 11. The pump cover straightening clamping assembly designed in the present invention can realize the straightening operation of the pump cover. Because the pump cover is usually equipped with a long tube, if the tube of the pump cover is in a bent or tilted state, it is easy to insert the pump cover into the bottle body inaccurately. Therefore, a pump cover straightening clamping head is designed, and the clamping piece is driven by the pump cover clamping cylinder to clamp the tube of the pump cover and straighten it to a fixed position, so that the accuracy of the pump cover insertion can be ensured.

[0035] 12. The present invention also sets the third receiving plate on the second adjustment slide, which can slide close to or away from the bottle body transmission line. In this way, when the pump cover is needed to straighten the clamping head, it slides close to the bottle body transmission line, starts the pump cover clamping cylinder, and completes the clamping operation. In addition, the second adjustment slide is set on the second longitudinal slide rail, which can drive the pump cover straightening clamping head on the third receiving plate to adjust up and down, and adapt to different sizes of pump cover clamping.

The second adjusting slide 605 is also arranged on a second longitudinal slide rail 608.

[0064] Working principle: 1. First, place the bottle body 8 on the bottle body transmission line 1 for transmission. During the transmission process, the spacing of the bottle body 8 is controlled to meet the screwing requirements of the pump cover.

[0065] 2. According to the size of the bottle body 8, the first adjusting cylinder 509 is extended to adjust the distance between the first receiving plate 302, the second receiving plate 302 and the bottle body transmission line 1, and the first receiving plate 302 and the second receiving plate 302 slide on the first adjusting slide 507, so that when the pair of bottle body clamping blocks 305 are working, the distance between the two matches the size of the bottle body 8. At the same time, the second rotating shaft 510 is driven to rotate by the hand wheel 514 to realize the upper and lower heights of the entire first adjusting slide 507, and further realize the height adjustment of the first receiving plate 302 and the second receiving plate 302.

[0066] 3. According to the length of the pump cover 7, adjust the distance between the third receiving plate 601 and the bottle body transmission line 1, and realize the sliding of the third receiving plate 601 on the second adjustment slide 605 towards or away from the bottle body transmission line 1 by extending and retracting the second adjustment cylinder 607, and slightly adjust the upper and lower heights of the third receiving plate 601 by the second longitudinal slide rail 608.

[0067] 4. Place the pump cover 7 between the transmission chains 1001 in sequence. As the transmission chain 1001 is transmitted, the pump cover 7 is driven to approach the position close to the bottle cap transfer assembly 200. After approaching the bottle cap transfer assembly 200, the circular transmission line 2001 works to drive the receiving seat 2002 to move in a circular shape. When the receiving seat 2002 moves to the end position of the transmission chain 1001, the transmission chain 1001 drives the pump cover 7 to move into the receiving seat 2002. The circular transmission line 2001 drives the receiving seat 2002 and the pump cover 7 therein to the pump. The pump head moves in the direction of the pump head direction adjustment channel 2010, and the direction of the pump head is adjusted under the action of the pump head direction adjustment channel 2010. When the pump cover 7 moves to face the feeding clamping hand assembly 300, the telescopic cylinder 2007 is started, and the adjustable stop rod 2006 is flipped upward, and the clamping head 3001 is close to the receiving seat 2002. The clamping head 3001 is driven by the clamping claw cylinder 3002 to clamp the pump cover 7 to complete the feeding operation. After a round of feeding is completed, the clamping head 3001 returns to the position of the bottle cap transfer assembly 200 to continue the next round of feeding operation.

[0068] 5. After feeding, the clamping head 3001 clamps the pump cover 7 and moves to a position close to the clamping rotating head 201. The bottle body transmission line 1 is transmitted. When the bottle body 8 reaches the screwing station, the clamping cylinder 203 is controlled to extend and retract, so that the pump cover clamping claw 208 below it is in a grasping state. Several groups of clamping rotating heads 201 clamp the pump cover 7 through the first transverse slide rail 402 and the first longitudinal slide rail 403 to insert the pump cover 7 into the bottle body 8 on the bottle body transmission line 1. At the same time, the first driving motor 202 works, and the pump cover clamping claw 208 grabs the pump cover 7 and screws it. When the pump cover 7 is inserted into the bottle body 8 on the bottle body transmission line 1, the second adjustment slide 605 is controlled by the second adjustment slide rail 606 and the second longitudinal slide rail 608 to drive the third receiving plate 601 thereon to slide toward or away from the bottle body transmission line 1 and in the up and down directions. At the same time, the pump cover straightening clamping head 602 is opened to straighten the tube of the pump cover 7 so that the pump cover 7 can be accurately inserted into the bottle body 8.

[0069] 6. During the screwing process, the bottle body clamping cylinder 304 works, and a pair of bottle body clamping cylinders 304 clamp the bottle body 8 to stabilize the bottle body 8. During the operation of steps 5 and 6, the first transverse slide rail 402 and the second transverse slide rail 502 drive the clamping rotating head 201 and the bottle body clamping head 301 to be transported as a whole along the bottle body conveying line 1, which can not only realize the product without pausing, but also synchronously complete the screwing operation of the pump cover 7.

[0070] 7. After completing one round of screwing, the first transverse slide rail 402 and the second transverse slide rail 502 work to return the clamping rotating head 201 and the bottle body clamping head 301 to their initial positions, and continue the next round of screwing operation.
