Description

Technical Field

[0001] The present invention relates to the technical field of food and drug packaging machinery and equipment, and particularly relates to a barrel lid picking and placing device, a barrel lid picking and placing system, and a barrel lid picking and placing method. Background Art

[0002] In the existing aluminum barrel cleaning and filling line, the aluminum lid picking and placing device picks the aluminum lid on a basket (a placement rack for placing aluminum barrels, also called a hanging basket) by one-time positioning. However, the basket for placing aluminum lids (also called a placement rack or a hanging basket) is reused multiple times, and there will be a situation of mixed use. When different baskets are used at different workstations, there will be a situation of misalignment in positioning. In this way, it is very difficult for the aluminum lid picking and placing device to ensure that the lid is positioned at the center of the aluminum lid each time, and the picking accuracy is insufficient. During the lid covering process, the center of the aluminum lid is prone to shift from the center of the aluminum barrel, resulting in lid covering failure. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a barrel lid picking and placing device, a barrel lid picking and placing system, and a barrel lid picking and placing method that can improve the picking accuracy, prevent the barrel lid from shifting from the center of the barrel body after lid covering, and avoid lid covering failure.

The barrel body conveying mechanism is provided with a lid covering station at a position corresponding to the hanging basket placement station. The lid covering station is provided with a barrel body fixing mechanism. The barrel lid transfer mechanism is used to transfer the barrel lid on the hanging basket placement station to the barrel lid positioning platform, and to transfer the barrel lid on the barrel lid positioning platform to the barrel body at the lid covering station. The barrel lid transfer mechanism is provided with a suction cup for picking and placing the barrel lid. The barrel lid positioning platform is provided with a centering mechanism and a centering position. The centering mechanism is used to move the barrel lid on the barrel lid positioning platform to the centering position. The barrel lid transfer mechanism sucks the barrel lid at the centering position and transfers it to the barrel body at the lid covering station.

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

[0007] The barrel lid transfer mechanism further includes a lifting bracket and a rotating arm. The rotating arm is arranged on the lifting bracket, and the suction cup is arranged on the rotating arm. The center of the centering position and the center of the barrel body at the lid covering station are both on the same circle with the rotation axis of the rotating arm as the center of the circle.

[0008] The centering mechanism includes a barrel lid circumferential limiting component for circumferentially resisting the barrel lid at the centering position and a pushing part for pushing the barrel lid to the centering position.

[0009] The circumferential limit assembly of the bucket lid includes two limit posts arranged at intervals and a mounting bracket, and the limit posts are arranged on the mounting bracket.

[0010] A slider is arranged on the limit post, a slide bar is arranged on the mounting bracket, the slider is slidably arranged on the slide bar, and a locking member is arranged on the slider.

[0011] The rotating arm includes a radial section and a chordal section. One end of the radial section is arranged on the lifting bracket, and the other end is connected to the chordal section. The pushing part and the suction cup are both arranged on the chordal section.

[0012] The radial section coincides with the perpendicular bisector of the chordal section. Suction cups are arranged at both ends of the chordal section, the pushing part is arranged in the middle of the chordal section, and there are two groups of the circumferential limit assemblies of the bucket lid. The two groups of the circumferential limit assemblies of the bucket lid are symmetrically arranged with the central axis of the lifting bracket as the center.

[0013] The bucket body fixing mechanism includes two rotating clamps and two rotating seats arranged at intervals on one side of the bucket body conveying mechanism. The two rotating clamps are respectively arranged on the two rotating seats.

[0014] A bucket lid picking and placing system includes a hanging basket and the above-mentioned bucket lid picking and placing device. Multiple bucket lid placing spaces are arranged on the hanging basket, and the bucket lid positioning platform is arranged on the top of the hanging basket.

[0015] A bucket lid picking and placing method is carried out by using the above-mentioned bucket lid picking and placing system, and includes the following steps:

[0016] S1. The hanging basket is in place: Place the hanging basket on the hanging basket placing station;

[0017] S2. The first lid picking: The suction cup enters the bucket lid placing space from the side of the hanging basket, sucks the bucket lid, and then transfers and places the bucket lid on the bucket lid positioning platform; then, under the action of the centering mechanism, the center of the suction cup is aligned with the bucket lid.

[0018] S3. The second lid picking: The suction cup sucks the bucket lid again and covers the bucket lid on the bucket body at the lid covering station.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] The barrel lid picking and placing device of the present invention, the process of picking and placing the barrel lid: First, place the hanging basket on the hanging basket placement station; Second, the rotating arm makes the suction cup enter the barrel lid placement space from the side of the hanging basket. After sucking the barrel lid, transfer the barrel lid and place it on the barrel lid positioning platform; Then, the rotating arm rotates to make the pushing part push the barrel lid to move until the barrel lid abuts tightly between the two limit posts of the pushing part and the circumferential limit component of the barrel lid. At this time, the center of the suction cup is aligned with the barrel lid; Finally, the suction cup sucks the barrel lid again, and under the cooperation of the lifting bracket and the rotating arm, the suction cup and the barrel lid are placed above the center of the barrel body of the barrel body conveying mechanism, and the barrel lid is just placed on the barrel body. The pushing part and the suction cup are both arranged on the chordal section. After the suction cup places the barrel lid on the barrel lid positioning platform, the suction cup is separated from the barrel lid. The pushing part and the suction cup rotate together. During the co-rotation process, the pushing part pushes the barrel lid on the barrel lid positioning platform to directly below the suction cup (at this time, the two limit posts abut against the circumferential side of the barrel lid), realizing the centering of the suction cup and the barrel lid. The structure and the movement process are simple, and the occupied space is also small.

[0021] The barrel lid picking and placing system of the present invention, the barrel lid picking and placing system includes a hanging basket and the barrel lid picking and placing device of Embodiment 1. Multiple layers of barrel lid placement spaces are provided on the hanging basket, and the barrel lid positioning platform is arranged on the top of the hanging basket. This barrel lid picking and placing system has all the advantages of the barrel lid picking and placing device, that is, it improves the lid picking accuracy, prevents the barrel lid from deviating from the center of the barrel body after capping, and avoids capping failure.

[0022] The barrel lid picking and placing method of the present invention. Since it is difficult to center with the center of the barrel lid when the suction cup enters the barrel lid placement space from the side of the hanging basket to adsorb the barrel lid, the barrel lid is transferred to the barrel lid positioning platform. After centering the suction cup and the barrel lid on the barrel lid positioning platform through the centering mechanism, the suction cup sucks the centered barrel lid and covers the barrel lid on the barrel body at the capping station. In this way, the lid picking accuracy is improved, the barrel lid is prevented from deviating from the center of the barrel body after capping, and capping failure is avoided.

Detailed implementation mode

[0028] The following will further elaborate on the present invention in detail with reference to the specification drawings and specific embodiments.

[0029] Embodiment 1:

[0030] Figures 1 to 3 An embodiment of the barrel lid picking and placing device of the present invention is shown. The barrel lid picking and placing device includes a barrel body conveying mechanism 1, a hanging basket placement station 2, a barrel lid positioning platform 7, and a barrel lid transfer mechanism 3. The barrel body conveying mechanism 1 is provided with a lid adding station at a position corresponding to the hanging basket placement station 2. A barrel body fixing mechanism 5 is provided at the lid adding station. The barrel lid transfer mechanism 3 is used to transfer the barrel lid 8 on the hanging basket placement station 2 to the barrel lid positioning platform 7, and to transfer the barrel lid 8 on the barrel lid positioning platform 7 to the barrel body 9 at the lid adding station. The barrel lid transfer mechanism 3 is provided with a suction cup 33 for picking and placing the barrel lid 8. The barrel lid positioning platform 7 is provided with a centering mechanism and a centering position. The centering mechanism is used to move the barrel lid 8 on the barrel lid positioning platform to the centering position. The barrel lid transfer mechanism 3 sucks the barrel lid at the centering position and transfers it to the barrel body 9 at the lid adding station.

[0031] Barrel lid picking and placing process: First, place the hanging basket 6 on the hanging basket placement station 2; Second, the suction cup 33 enters the barrel lid placement space 61 from the side of the hanging basket 6, sucks the barrel lid 8, and then transfers the barrel lid 8 and places it on the barrel lid positioning platform 7; Then, under the action of the centering mechanism, align the center of the suction cup 33 with the barrel lid 8; Finally, the suction cup 33 sucks the barrel lid 8 again and covers the barrel lid 8 on the barrel body 9 at the lid adding station. Since it is difficult to align the center with the barrel lid 8 when the suction cup 33 enters the barrel lid placement space 61 from the side of the hanging basket 6 to adsorb the barrel lid 8, the barrel lid 8 is transferred to the barrel lid positioning platform 7. After the centering mechanism centers the suction cup 33 and the barrel lid 8 on the barrel lid positioning platform 7, the suction cup 33 sucks the centered barrel lid 8 and covers the barrel lid 8 on the barrel body 9 at the lid adding station. In this way, the lid picking accuracy is improved, the barrel lid 8 is prevented from deviating from the center of the barrel body 9 after lid adding, and lid adding failure is avoided.

[0032] In this embodiment, the suction cup 33 does not necessarily need to adsorb at the center of the bucket lid 8. It only needs to be set that the bucket lid 8 can be exactly placed on the bucket body 9. The bucket body fixing mechanism 5 fixes the bucket body 9 at a definite position. The installation and debugging personnel set the lid placing position of the suction cup 33 on the bucket body 9 and also set the lid taking position of the suction cup 33 at the centering position. The lid placing position and the lid taking position can be any position on the bucket lid 8, as long as it is ensured that the position of the lid placing position on the circle where the bucket opening is located is the same as the position of the bucket lid 8 where the lid taking position is located. The suction cup 33 sucking the center of the bucket lid 8 can improve the stability during the transfer of the bucket lid.

[0033] As Figure 3 shown, the hanging basket 6 is a storage rack for the bucket lid 8. Multiple bucket lids 8 are placed on the hanging basket 6. First, because the position of the hanging basket 6 placed on the hanging basket placing station 2 is not necessarily correct, and multiple bucket lids 8 are stacked on top of each other, there are also certain deviations in their positions. Therefore, during the lid taking process, the suction cup 33 does not necessarily adsorb to the same position of the bucket lid 8. The deviation in position causes deviation during the lid placing process. The bucket lid positioning platform 7 is arranged on the top of the hanging basket 6. The side wall of the hanging basket 6 discharges the lid. The side wall of the hanging basket 6 is provided with a detachable limiting rod, which can prevent the bucket lid 8 from falling during the transfer of the hanging basket 6. When the hanging basket 6 is placed on the hanging basket placing station 2, the limiting rod needs to be disassembled.

[0034] The bucket lid positioning platform 7 is arranged on the top of the hanging basket 6. Since the hanging basket 6 will carry the bucket lid through cleaning and sterilization, therefore, in order to meet the aseptic requirements (the components in contact with the bucket lid need to be cleaned and sterilized), the bucket lid positioning platform 7 and the hanging basket 6 are set as a whole, without the need to clean and sterilize the bucket lid positioning platform 7 separately, making clever use of the structure of the hanging basket 6.

[0035] In this embodiment, as Figure 2 shown, the bucket lid transfer mechanism 3 further includes a lifting bracket 31 and a rotating arm 32. The rotating arm 32 is arranged on the lifting bracket 31, and the suction cup 33 is arranged on the rotating arm 32. The center of the centering position and the center of the bucket body 9 at the lid covering station are both on the same circle with the rotation axis of the rotating arm 32 as the center. The lifting bracket 31 and the rotating arm 32 drive the suction cup 33 to move back and forth between the hanging basket placing station 2, the bucket lid positioning platform 7 and the lid covering station for lid covering. The structure is simple and the operation is convenient.

[0036] In this embodiment, the centering mechanism includes a bucket lid circumferential limiting component 4 for circumferentially resisting the bucket lid at the centering position and a pushing part 34 for pushing the bucket lid to the centering position. The pushing part 34 and the bucket lid circumferential limiting component 4 cooperate to achieve the centering of the suction cup 33 and the bucket lid 8. The structure is simple and the design is ingenious.

[0037] In this embodiment, the circumferential limiting component 4 of the barrel cover includes two limiting columns 41 arranged at intervals and a mounting bracket 42, and the limiting columns 41 are arranged on the mounting bracket 42. Specifically, the mounting bracket 42 is fixed on the hanging basket placing station 2. In this embodiment, there are not less than two limiting columns 41. The two limiting columns 41 and the pushing part 34 cooperate to determine the center position of the barrel cover. It can also be to determine the center position of the barrel cover through an arc; in fact, the arc and the cooperation of the two limiting columns 41 and the pushing part 34 can determine the center position of the barrel cover by the same principle (three points determine the center of a circle), and the arc can be regarded as having multiple points.

[0038] In this embodiment, a slider 411 is arranged on the limiting column 41, a slide bar 421 is arranged on the mounting bracket 42, the slider 411 slides on the slide bar 421, and a locking part 412 is arranged on the slider 411. In this way, the two limiting columns 41 can slide along the slide bar 421 through the slider 411 to adjust the interval between the two to be suitable for resisting and limiting barrel covers 8 of different sizes.

[0039] In this embodiment, the rotating arm 32 includes a radial section 321 and a chordal section 322. One end of the radial section 321 is arranged on the lifting bracket 31, and the other end is connected to the chordal section 322. The pushing part 34 and the suction cup 33 are both arranged on the chordal section 322.

[0040] Process of taking and placing the barrel cover: First, place the hanging basket 6 on the hanging basket placing station 2; Second, the rotating arm 32 makes the suction cup 33 enter the barrel cover placing space 61 from the side of the hanging basket 6. After sucking the barrel cover 8, transfer and place the barrel cover 8 on the barrel cover positioning platform 7; Then, the rotating arm 32 rotates to make the pushing part 34 push the barrel cover 8 to move until the barrel cover 8 abuts tightly between the pushing part 34 and the two limiting columns 41 of the circumferential limiting component 4 of the barrel cover. At this time, the center of the suction cup 33 is aligned with the barrel cover 8; Finally, the suction cup 33 sucks the barrel cover 8 again, and under the combined drive of the lifting bracket 31 and the rotating arm 32, cover the barrel cover 8 on the barrel 9 on the barrel body conveying mechanism 1. The pushing part 34 and the suction cup 33 are both arranged on the chordal section 322. After the suction cup 33 places the barrel cover 8 on the barrel cover positioning platform 7, the suction cup 33 is separated from the barrel cover 8, and the pushing part 34 and the suction cup 33 rotate together. During the joint rotation, the pushing part 34 pushes the barrel cover 8 on the barrel cover positioning platform 7 directly below the suction cup 33 (at this time, the two limiting columns 41 abut against the circumferential side of the barrel cover 8), realizing the centering of the suction cup 33 and the barrel cover 8. The structure and the movement process are simple, and the occupied space is also small.

[0041] In this embodiment, the perpendicular bisector of the radial segment 321 coincides with that of the chordal segment 322. Suction cups 33 are provided at both ends of the chordal segment 322, and the pushing part 34 is provided in the middle of the chordal segment 322. There are two sets of circumferential limiting components 4 for the barrel lid, and the two sets of circumferential limiting components 4 for the barrel lid are symmetrically arranged with the central axis of the lifting bracket 31 as the center. In this way, two hanging baskets 6 can be placed at the hanging basket placement station 2 at one time, and the two hanging baskets 6 are symmetrically arranged with the central axis of the lifting bracket 31 as the center, corresponding to the two sets of circumferential limiting components 4 for the barrel lid respectively. In this way, the two suction cups 33 at both ends of the chordal segment 322 can be used to alternately remove the lids of the two hanging baskets 6 respectively, improving the working efficiency.

[0042] In this embodiment, the barrel body fixing mechanism 5 includes two rotating clamps 51 and two rotating seats 52 spaced on one side of the barrel body conveying mechanism 1. The two rotating clamps 51 are respectively arranged on the two rotating seats 52. Before the barrel body 9 reaches the lid covering station, the two rotating seats 52 rotate in opposite directions to open the two rotating clamps 51 to the side of the barrel body conveying mechanism 1. After the barrel body 9 reaches the lid covering station, the two rotating seats 52 rotate in opposite directions to make the two rotating clamps 51 move towards each other and merge on one side of the barrel body conveying mechanism 1 to clamp the barrel body 9 at the lid covering station, thereby realizing the fixation of the barrel body 9. The structure is simple and the operation is convenient. Specifically, the rotating clamp 51 is arc-shaped.

[0043] Embodiment Two:

[0044] A barrel lid picking and placing system, the barrel lid picking and placing system includes a hanging basket 6 and the barrel lid picking and placing device of Embodiment One. Multiple barrel lid placement spaces 61 are provided on the hanging basket 6, and the barrel lid positioning platform 7 is arranged on the top of the hanging basket 6. This barrel lid picking and placing system has all the advantages of the barrel lid picking and placing device, that is, it improves the lid picking accuracy, prevents the barrel lid 8 from deviating from the center of the barrel body 9 after lid covering, and avoids lid covering failure.

[0045] Embodiment Three:

[0047] S1. The hanging basket 6 is in place: Place the hanging basket 6 on the hanging basket placement station 2;

[0048] S2. First lid picking: The suction cup 33 enters the barrel lid placement space 61 from the side of the hanging basket 6, sucks the barrel lid 8, and then transfers and places the barrel lid 8 on the barrel lid positioning platform 7; Then, under the action of the centering mechanism, the center of the suction cup 33 is aligned with the barrel lid 8;

[0049] S3. Second lid picking: The suction cup 33 sucks the barrel lid 8 again and covers the barrel lid 8 on the barrel body 9 at the lid covering station.

[0050] Since it is difficult for the suction cup 33 to be centered with the center of the lid 8 when the suction cup 33 enters the lid placement space 61 from the side of the hanging basket 6 to adsorb the lid 8, the lid 8 is transferred to the lid positioning platform 7. After the suction cup 33 and the lid 8 are centered on the lid positioning platform 7 through the centering mechanism, the suction cup 33 sucks the centered lid 8 and covers the lid 8 on the barrel 9 at the capping station. In this way, the lid picking accuracy is improved, the deviation of the lid 8 from the center of the barrel 9 after capping is prevented, and capping failure is avoided.

[0051] The specific steps of the lid picking and placing method are as follows:

[0052] S1. The hanging basket 6 is in place: The hanging basket 6 is placed on the hanging basket placement station 2;

[0053] S2. First lid picking: The rotating arm 32 makes the suction cup 33 enter the lid placement space 61 from the side of the hanging basket 6. After sucking the lid 8, the lid 8 is transferred and placed on the lid positioning platform 7; The rotating arm 32 rotates to make the pushing part 34 push the lid 8 to move until the lid 8 abuts tightly between the pushing part 34 and the lid circumferential limiting component 4. At this time, the center of the suction cup 33 is aligned with the lid 8;

[0054] S3. Second lid picking: The suction cup 33 sucks the lid 8 again, and under the combined drive of the lifting bracket 31 and the rotating arm 32, the lid 8 is covered on the barrel 9 on the barrel conveying mechanism 1.
