Description

Technical Field

[0001] The utility model relates to the field of assembly machines, in particular to an automatic assembly machine for plastic covers. Background Art

[0002] With the development of food culture, various tea beverages are widely popularized. Various tea beverage stores on the market usually use plastic cups to hold tea beverages. Each cup of tea beverage is equipped with a cup lid and a straw. In order to facilitate tea beverage masters and customers to distinguish different tea beverages, a label for easily identifying different types of tea beverages is usually pasted on the cup lid. And in order to facilitate tea beverage masters to fill and pack tea beverages, currently on the market, a straw is usually assembled on the cup lid, and a label for identifying the type of tea beverage is attached to the surface of the cup lid to fix the straw. After the plastic cup is filled with tea beverage, the tea beverage master covers the cup with the cup lid equipped with the straw and the corresponding label, and the filling work of the tea beverage is completed simply and quickly. At present, most cup lid production enterprises on the market use manual labor to assemble straws on cup lids and manually paste labels for identifying the types of tea beverages. The operation method of manually pasting labels on cup lids not only has the deficiencies of large positioning error of label pasting, poor label pasting effect and low label pasting efficiency, but also results in high labor intensity of workers and high labor cost of enterprises. It cannot meet the requirements of large-scale batch production and automated production of enterprises, and is not conducive to the development of industrialization. Summary of the Invention

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art and provide an automatic assembly machine for plastic covers.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions: The automatic assembly machine for plastic covers includes a workbench, a turntable mechanism, an upper cover conveying line, an upper cover misalignment lifting and feeding mechanism, a straw assembly mechanism, a label pasting mechanism, a finished product discharging mechanism and a finished product discharging conveying line. The upper cover misalignment lifting and feeding mechanism, the straw assembly mechanism, the label pasting mechanism and the finished product discharging mechanism are sequentially arranged around the turntable mechanism. The upper cover misalignment lifting and feeding mechanism is connected to the upper cover conveying line, and the finished product discharging mechanism is connected to the finished product discharging conveying line. The upper cover conveying line conveys and prepares the upper cover group (i.e., formed by stacking two or more upper covers). The upper cover misalignment lifting and feeding mechanism misfeeds the upper cover group and sequentially places the upper covers on the turntable mechanism. The straw assembly mechanism assembles straws on the upper covers on the turntable mechanism. The label pasting mechanism pastes labels on the upper covers equipped with straws. The finished product discharging mechanism classifies and discharges the upper covers with labels pasted on them. The finished product discharging conveying line conveys the upper covers in parallel for discharging.

[0005] Preferably, the upper cover misalignment and lifting feeding mechanism includes an upper cover misalignment component. One side of the upper cover misalignment component is provided with an upper cover lifting component, and one side of the upper cover lifting component is provided with an upper cover feeding conveyor component. Above the upper cover lifting component, there are a first CCD camera and a first light source. The upper cover misalignment component misplaces and pushes a set of upper covers (referred to as the upper cover group) that are conveyed at the front on the upper cover conveyor line onto the upper cover lifting component. The first CCD camera takes pictures of the uppermost upper cover in the upper cover group on the upper cover lifting component to detect the orientation and position of the upper cover. The upper cover feeding conveyor component sucks the uppermost upper cover in the upper cover group and places it into the turntable mechanism.

[0006] The upper cover misalignment component includes an upper cover pushing fixture, which is connected to a first driving unit. On both sides of the upper cover pushing fixture, a first side baffle and a second side baffle are respectively installed. One side of the upper cover pushing fixture is provided with a first linear sliding module, and the first linear sliding module is arranged on the same side as the first side baffle. An upper cover fixture moving seat is arranged on the first linear sliding module, and the upper cover fixture moving seat is connected and installed with the upper cover pushing fixture. A detection optical fiber is arranged above the upper cover pushing fixture, and a buffer baffle is arranged on the upper cover fixture moving seat. First buffers and second buffers are respectively arranged at both ends of the first linear sliding module. The first driving unit is fixed on the workbench through a first mounting plate, and the detection optical fiber is fixed on the upper cover pushing fixture through an optical fiber mounting plate.

[0007] By adopting the above technical solution, the detection optical fiber detects whether the upper cover group is missing on the upper cover conveyor line. The first buffer and the second buffer limit the moving stroke of the buffer baffle to define the starting position and the ending position of misplacing and pushing the upper cover group. Since the upper cover misalignment component is arranged on one side of the output end of the upper cover conveyor line for conveying upper covers, when the first driving unit pushes the upper cover pushing fixture in the direction of the upper cover lifting component, it can push a set of upper covers that are conveyed at the front on the upper cover conveyor line onto the upper cover lifting component, and the first side baffle blocks and positions a set of upper covers (i.e., the first set of upper covers) that are conveyed at the front on the upper cover conveyor line. After the upper cover misalignment component misplaces and pushes the first set of upper covers, since the second side baffle moves along with the movement of the upper cover pushing fixture, at this time, the second side baffle is facing the second set of upper covers on the upper cover conveyor line, so that the second side baffle can block the conveyance of the second set of upper covers on the upper cover conveyor line to prevent the second set of upper covers from falling off the upper cover conveyor line. When the first driving unit drives the upper cover pushing fixture to retreat and reset, the second side baffle resets along with the retreat of the upper cover pushing fixture to withdraw or release the block on the second set of upper covers, so that the upper cover conveyor line continues to convey the second set of upper covers, and the first side baffle blocks the second set of upper covers to position its conveyance, making the second set of upper covers become a set of upper covers that are conveyed at the front on the upper cover conveyor line. It realizes misplacing and pushing the upper cover group while ensuring the orderly conveyance and feeding of the upper cover group.

[0008] The upper cover loading and conveying assembly includes a first lead screw linear module, which is connected to a second driving unit.

When the first clamping block and the second clamping block close relative to each other, they can clamp the upper cover to prevent the two adjacent upper covers from sticking together. The second driving unit and the third driving unit cooperate to drive the first upper cover suction head to place the sucked upper cover on the turntable mechanism; wherein, the pulling force of the first elastic member cancels out the gravity of the upper cover lifting moving plate and the components thereon, so that the upper cover lifting moving plate is not affected by its own gravity when moving up and down under the drive of the third driving unit, and the second elastic member buffers the stroke of the first upper cover suction head when sucking and placing the upper cover.

The eighth drive unit, the ninth drive unit and the tenth drive unit cooperate to drive the straw suction head to pick up the straws from the first tray, and the third CCD camera takes pictures of the straws on the straw suction head to identify the orientation of the straws. When the third CCD camera identifies that the orientation of the straws is incorrect, the eleventh drive unit drives the straw suction head to rotate to turn the straws to the direction required for assembly.

After the upper cover misalignment assembly 41 completes the misaligned pushing of the first group of upper covers, the second side baffle 413 blocks the conveyance of the second group of upper covers on the upper cover conveying line 3 to prevent the second group of upper covers from falling off the upper cover conveying line 3. When the first driving unit 411 drives the upper cover pushing jig 410 to retreat and reset on the first linear sliding module 414, the second side baffle 413 withdraws or releases the block on the second group of upper covers, and the upper cover conveying line 3 continues to convey the second group of upper covers. The first side baffle 412 blocks the second group of upper covers to position its conveyance, making the second group of upper covers become a group of upper covers conveyed at the front on the upper cover conveying line 3, which can realize misaligned pushing of the upper cover group while ensuring the orderly conveyance and feeding of the upper cover group through the upper cover misalignment assembly 41.

[0091] After the upper cover group is pushed into the lifting support plate 422 in the upper cover lifting assembly 42 by the upper cover misalignment assembly 41, whenever the uppermost upper cover 9 in the upper cover group on the lifting support plate 422 is taken away by the upper cover feeding and conveying assembly 43, the seventh driving unit 423 drives the lifting support plate 422 to raise the upper cover group by the height of one upper cover, so that the uppermost upper cover 9 in the upper cover group always remains at a predetermined height, and the lifting guide rod 424 can support the upper covers stacked in the upper cover group to prevent the upper cover group from tilting.

[0092] The second driving unit 431 and the third driving unit 433 in the upper cover loading and conveying assembly 43 cooperate to drive the first upper cover suction head 4396 to suck the upper cover 9 from the lifting pallet 422 of the upper cover lifting assembly 42, convey the upper cover 9 and place the upper cover on the turntable mechanism 2. The first CCD camera 44 in the upper cover loading and conveying assembly 43 takes pictures of the upper cover 9 on the upper cover lifting assembly 42 to identify the orientation and position of the upper cover 9. When the first photoelectric induction switch 436 senses that the first light shielding sheet 438 has risen in place, the third driving unit 433 stops driving the first upper cover suction head 4396 to rise; the fifth driving unit 4397 and the sixth driving unit 4398 respectively and simultaneously drive the first clamping block 4399 and the second clamping block 43991 to close or open with each other. When the first clamping block 4399 and the second clamping block 43991 close with each other, they can clamp the upper cover 9 to prevent the two adjacent upper covers 9 in the upper cover group from sticking together; when the second driving unit 431 and the third driving unit 433 cooperate to drive the first upper cover suction head 4396 to place the upper cover 9 on the turntable mechanism 2, the pulling force of the first elastic member 439 cancels out the gravity of the upper cover lifting and moving plate 437 and the components on the upper cover lifting and moving plate 437, so that when the third driving unit 433 drives the upper cover lifting and moving plate 437 to move up and down, it is not affected by its gravity. The second elastic member 4393 buffers the stroke of the first upper cover suction head 4396 when sucking and placing the upper cover 9.

[0093] The twenty-fourth driving unit 24 in the turntable mechanism 2 drives the turntable 21 to rotate, so that the upper cover 9 placed on the upper cover jig 22 can rotate with the rotation of the turntable 21 and pass through the straw assembly mechanism 5, the label pasting mechanism 6 and the finished product unloading mechanism 7. The straws in the straw assembly mechanism 5 are first stacked on the hopper 51. The linear vibrator 52 vibrates the hopper 51 to convey the straws to the first tray 50. The second CCD camera 53 takes pictures of the straws on the first tray 50 to identify the positions of the straws on the first tray 50. The eighth driving unit 57, the ninth driving unit 59 and the tenth driving unit 591 in the straw assembly mechanism 5 cooperate to drive the straw suction head 5905 to suck the straws from the first tray 50. The third CCD camera 5906 takes pictures of the straws on the straw suction head 5905 to identify the orientation of the straws; when the straws on the straw suction head 5905 have the wrong orientation, the eleventh driving unit 5904 drives the straw suction head 5905 to rotate to rotate the straws so that the straws can be rotated to the direction required for assembly; the eighth driving unit 57, the ninth driving unit 59 and the tenth driving unit 591 cooperate to drive the straw suction head 5905 to assemble the straws onto the upper cover 9 that rotates into the straw assembly mechanism 5 with the rotation of the turntable 21 in the turntable mechanism 2. It can automatically complete a series of operations such as straw feeding and conveying, automatic detection of straw orientation, automatic correction of straw orientation and assembling straws onto the upper cover through the straw assembly mechanism 5, and has the advantages of high positioning accuracy, high assembly efficiency and good assembly effect for assembling straws onto the upper cover.

[0094] The turntable mechanism 2 rotates the upper cover 9 with the straws installed into the label pasting mechanism 6. The fifth CCD camera 10 takes a picture of the upper cover 9 on the turntable mechanism 2 that has completed the straw assembly process to identify the position of the upper cover 9 in the upper cover jig 22 of the turntable mechanism 2 to avoid the upper cover 9 from being displaced in the upper cover jig 22 and affecting the subsequent labeling accuracy, which provides a guarantee for the subsequent accurate pasting of the label onto the surface of the upper cover 9. The fifth elastic member 616 and the sixth elastic member 618 in the label unwinding assembly 61 of the label pasting mechanism 6 push the first pressing block 613 and the second pressing block 614 respectively, so that the first pressing block 613 and the second pressing block 614 move relatively close to each other and press the material tray shaft 610 to damp the rotation of the pressing material tray shaft 610, provide damping for the unwinding of the second material tray 611, so that the label material strip 12 of the second material tray 611 is always kept in a tensioned state during the unwinding process, which ensures a good unwinding effect of the label material strip 12 and provides accuracy guarantee for subsequent labeling operations. The starting end of the label material strip 12 unwound from the second material tray 611 is pulled to the label stripping assembly 65 through the label material strip fixing assembly 64.

[0095] When the twelfth driving unit 645 in the label material tape fixing assembly 64 of the label pasting mechanism 6 drives the third pressing block 646 to move downward, the label material tape 12 transmitted through it can be pressed tightly on the material tape support plate 641 and cooperate with the label peeling assembly 65 to complete the work of peeling the protective paper. Through the first positioning groove 642, the distance between the first limit block 643 and the second limit block 644 can be adjusted to suit the use of label material tapes 12 of different widths, thereby achieving the purpose of its strong versatility.

[0096] When the label tape 12 is conveyed past the label peeling assembly 65 in the label pasting mechanism 6, the thirteenth driving unit 659 in the label peeling assembly 65 drives the label peeling vertical plate 650 to reciprocate linearly on the seventh linear sliding module 651 and the eighth linear sliding module 652 through the lead screw kit 655. When the thirteenth driving unit 659 drives the label peeling vertical plate 650 to move forward on the seventh linear sliding module 651 and the eighth linear sliding module 652 (i.e., move in the direction away from the label tape fixing assembly 64), the label peeling vertical plate 650 drives the label peeling knife 653 to move forward to pull out a certain length of the label tape 12. When the third photoelectric induction switch 6592 senses the third light-shielding sheet 6593, the thirteenth driving unit 659 stops pushing the label peeling knife 653 to pull out the label tape 12. Then, the fifteenth driving unit 673 in the label conveying assembly 67 drives the first suction cup 674 to descend to suck the label from the label tape 12. The thirteenth driving unit 659 in the label peeling assembly 65 drives the label peeling knife 653 to retreat to peel the protective paper tape. After the protective paper tape of the label tape 12 is peeled from the label, the fourteenth driving unit 671 and the fifteenth driving unit 673 cooperate to convey the label to the label transfer table 66, which realizes label peeling and label conveying.

[0097] When the sixteenth driving unit 6900, the seventeenth driving unit 6903, and the eighteenth driving unit 6905 in the label pasting assembly 690 cooperate, they can drive the second suction cup 6918 to suck the label from the label transfer table 66. The fourth CCD camera 691 takes pictures of the label on the second suction cup 6918 to identify the orientation and position of the label. When the orientation and position of the label are incorrect, the nineteenth driving unit 6917 rotates the second suction cup 6918 to correct the angle of the label. Then, the sixteenth driving unit 6900, the seventeenth driving unit 6903, and the eighteenth driving unit 6905 cooperate to drive the second suction cup 6918 to attach the label to the upper cover 9 that enters the label pasting assembly 690 as the turntable mechanism 2 rotates and drive the label roller 6920 to roll back and forth on the label to firmly paste the label on the upper cover 9. This not only ensures the accurate positioning of the label pasted on the upper cover 9, but also ensures good pasting effect and high pasting efficiency for pasting the label on the upper cover 9.

[0098] The peeled protective paper tape is recycled through the protective paper recycling module 69. The twentieth driving unit 691 in the protective paper recycling module 69 can drive the protective paper conveying component 693 to rotate through the fourth pulley kit 694 to convey the protective paper tape.

[0099] The ninth elastic member 6976 in the protective paper conveying component 693 presses against the fourth pressing block 6975. The fourth pressing block 6975 can tightly press the eccentric shaft 6992. Pull the wrench 6994 to rotate the eccentric shaft 6992. When the eccentric groove 6993 is misaligned with the eccentric supporting plate 6974 as the eccentric shaft 6992 rotates, the driven roller 6991 rises and separates from the driving roller 699. At this time, it is convenient to draw the starting end of the protective paper tape through between the driving roller 699 and the driven roller 6991, and stick the starting end of the protective paper tape to the recycling roller 692. When the eccentric groove 6993 on the eccentric shaft 6992 faces the eccentric supporting plate 6974, the driven roller 6991 descends and engages with the driving roller 699. At this time, the driving roller 699 drives the driven roller 6991 to rotate to convey the protective paper tape. The twentieth driving unit 691 can drive the recycling roller 692 to rotate through the fourth pulley kit 694 and the fifth pulley kit 695 in sequence to wind the protective paper tape and tighten the protective paper, thereby realizing the automatic recycling of the protective paper tape.

[0100] When the turntable mechanism 2 rotates the upper cover 9 that has completed the processes of assembling the straw and pasting the label into the finished product blanking mechanism 7, the sixth CCD camera 77 in the finished product blanking mechanism 7 takes a picture of the upper cover 9 on the turntable mechanism 2 that has completed the processes of assembling the straw and pasting the label to identify whether the label attached to the upper cover 9 is qualified. The twenty-first driving unit 71, the twenty-second driving unit 73 and the twenty-third driving unit 75 cooperate to drive the second upper cover suction head 76 to suck the upper cover 9 with the attached label from the turntable mechanism 2, and according to the result of the picture taken by the sixth CCD camera 77 for the upper cover 9, discard the defective products onto the funnel 79 for defective product recycling or place the qualified products on the finished product blanking conveyor line 8 for stacking the upper covers 9. When the stacking of the upper covers 9 reaches a predetermined number to form a group of upper covers, the twenty-third driving unit 75 cooperates with the second upper cover suction head 76 to place the upper covers in a staggered manner to continue the stacking of the next group of upper covers 9. The group of upper covers is arranged in two columns on the finished product blanking conveyor line 8 for blanking and conveying, which has the advantage of high blanking and conveying efficiency. At the same time, it avoids the need to configure multiple finished product blanking conveyor lines 8 for blanking, thereby reducing the volume of the equipment and the production cost of the equipment.

[0101] Its overall structural design enables a series of operations to be completed on one device, including upper cover conveying, upper cover misaligned feeding, upper cover orientation detection, upper cover orientation correction, straw feeding and conveying, automatic straw orientation detection, automatic straw orientation correction, assembling straws onto the upper cover, label tape conveying, label sucking, protective paper tape peeling, labeling the upper cover, and recycling the protective paper tape. Moreover, the process of assembling straws onto the upper cover and labeling the upper cover with assembled straws is fully automated, eliminating the need for manual intervention in straw assembly and labeling of the upper cover. This results in advantages such as high assembly efficiency, high assembly accuracy, good assembly effect, high labeling efficiency, high labeling accuracy, and good labeling effect. It also significantly reduces the labor intensity of workers, lowers the labor cost of enterprises, decreases the volume of equipment, and reduces the production cost of equipment. It effectively solves the problems existing in most cup lid production enterprises in the market currently, where manual labor is used for straw assembly on cup lids and manual labeling of labels for identifying tea beverage types, leading to low straw assembly efficiency, poor label positioning accuracy, poor labeling effect, low labeling efficiency, high labor intensity of workers, and high labor cost of enterprises. In addition, in addition to being applicable to automatically assembling straws and labeling the upper cover, the present utility model is also applicable to assembling spoons and labeling the upper cover, achieving the purpose of strong versatility, strong practicality, and wider applications.

[0102] The above embodiments are merely examples of the present utility model and are not intended to limit the implementation and scope of rights of the present utility model. Any technical solutions identical or equivalent to the content described in the claims of the present utility model shall be included within the protection scope of the present utility model.
