Description

Technical Field

[0001] The utility model relates to the technical field of processing of canned products, in particular to a lower cover mounting device. Background Art

[0002] Before filling canned products, a lower cover needs to be installed at the bottom of the can body. In the existing lower cover mounting device, after the material taking mechanism picks up the lower cover, the lower cover is placed at the top end of the inverted can body. After the placement, the transportation device drives the can body to be transported to the next working station to realize the welding of the lower cover. However, when the existing lower cover mounting device is in use, on the one hand, since the position of the lower cover on the can body is not restricted, the lower cover needs to be transported with the can body for a certain distance to reach the next working station. During the above transportation process, the lower cover may move relative to the can body, resulting in inaccurate final position of the lower cover fixed on the can body, and further causing the lower cover to be unable to tightly seal the can body, resulting in losses of the lower cover and the can body; on the other hand, when the material taking mechanism picks up the lower cover, the phenomenon of picking up two lower covers at one time may occur. Content of the Utility Model

[0003] The purpose of the utility model is to provide a lower cover mounting device, which can not only ensure the position accuracy of the lower cover fixed on the can body, but also take out one lower cover at the bottommost layer at one time, improving the product qualification rate.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0014] Further, the material distribution assembly includes a material distribution block rotatably connected to the material storage rack. One end of the material distribution block has a pin extending in the vertical direction, and the other end has a first blocking piece and a second blocking piece.

[0036] This embodiment provides a lower cover installation device, such as Figure 1 As shown, it includes a material storage mechanism 1, a material taking mechanism 2, a positioning mechanism 3 and a dotting mechanism 4, wherein:

[0037] The storage mechanism 1 is used to store multiple stacked lower covers 5;

[0038] The material taking mechanism 2 is located below the material storage mechanism 1, and is used to take out the lower cover 5 at the bottom of the material storage mechanism 1 and place the lower cover 5 on the tank body 6;

[0039] The positioning mechanism 3 and the dotting mechanism 4 are both located below the material taking mechanism 2 . The positioning mechanism 3 is used to limit the tank body 6 to below the material taking mechanism 2 , and the dotting mechanism 4 is used to press the edge of the lower cover 5 so that the lower cover 5 is deformed and stuck on the tank body 6 .

[0040] refer to Figure 1When using the above-mentioned lower cover installation device, multiple stacked lower covers 5 are stored in the storage mechanism 1, and the picking mechanism 2 takes out the lower cover 5 at the bottom of the storage mechanism 1; then the positioning mechanism 3 limits the tank body 6 to the bottom of the picking mechanism 2, so that the tank body 6 is arranged opposite to the lower cover 5 on the picking mechanism 2; then the picking mechanism 2 places the lower cover 5 on the tank body 6; finally, the dotting mechanism 4 presses the edge of the lower cover 5, so that the edge of the lower cover 5 is deformed and stuck on the tank body 6.

[0041] The lower cover installation device provided in the above embodiment can press the edge of the lower cover 5 after the lower cover 5 is placed on the tank body 6, so that the edge of the lower cover 5 is deformed and stuck on the tank body 6, and the position of the lower cover 5 relative to the tank body 6 is limited, thereby ensuring that the lower cover 5 will not be displaced relative to the tank body 6 during the subsequent transportation process, and ensuring the position accuracy of the lower cover 5 fixed on the tank body 6. In addition, the material taking mechanism 2 can take out the bottommost lower cover 5 in the material storage mechanism 1 at a time, avoiding waste of the lower cover 5 and improving the product qualification rate.

[0042] The structure of the dotting mechanism 4 is described in detail below:

[0043] In an optional embodiment, if Figure 1 As shown, the dot-marking mechanism 4 includes a first dot-marking component 41 and a second dot-marking component 42 , and the first dot-marking component 41 and the second dot-marking component 42 are arranged opposite to each other along the radial direction of the can body 6 limited by the positioning mechanism 3 .

[0044] By pressing the first dot-punching assembly 41 and the second dot-punching assembly 42 together, the lower cover 5 can be deformed at both ends along its own radial direction, so that it is stuck on the can body 6 to avoid displacement relative to the can body 6 during subsequent transportation.

[0045] The first dotting assembly 41 and the second dotting assembly 42 may adopt the same structure, and the structures of the two will be specifically described by taking the first dotting assembly 41 as an example.

[0046] In an optional embodiment, if Figure 1 The first dotting assembly 41 shown includes a first driver 411 and a clamping block 412. The first driver 411 is connected to the clamping block 412. The first driver 411 is used to drive the clamping block 412 to move radially along the tank body 6 limited by the positioning mechanism 3, thereby pressing the edge of the lower cover 5 so that the edge of the lower cover 5 is curled and stuck on the tank body 6.

[0047] It should be noted that any structure that can drive the clamping block 412 to move radially along the can body 6 limited by the positioning mechanism 3 can be the first driver 411 mentioned in the above embodiments. For example, the first driver 411 can be a mechanism that performs linear motion, such as a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc., or a combination of a mechanism that performs rotational motion and a transmission mechanism, such as including a rotating motor and a connecting rod slider mechanism connected to the rotating motor, and the connecting rod slider mechanism can convert the rotational motion of the rotating motor into linear motion.

[0048] In a preferred embodiment, the first driver 411 is a pneumatic cylinder.

[0049] In an alternative embodiment, one end of the clamping block 412 is connected to the power output end of the first driver 411. As Figure 2 shown, the end of the clamping block 412 away from the first driver 411 includes a first limiting portion 4121 and a second limiting portion 4122 connected below the first limiting portion 4121, and a notch 4123 for pressing the edge of the lower cover 5 is formed between the first limiting portion 4121 and the second limiting portion 4122.

[0050] During use, the first driver 411 drives the clamping block 412 to approach the can body 6 radially along the can body 6, and the edge of the lower cover 5 enters the notch 4123 formed between the first limiting portion 4121 and the second limiting portion 4122. As the clamping block 412 continues to approach, the notch 4123 squeezes the edge of the lower cover 5, causing the edge of the lower cover 5 to bend downward and be clamped on the can body 6.

[0051] In an alternative embodiment, as Figure 2 shown, the notch 4123 has a certain downward bending arc, so that when the notch 4123 squeezes the edge of the lower cover 5, it can better force the lower cover 5 to bend downward.

[0052] In a preferred embodiment, the first limiting portion 4121 and the second limiting portion 4122 are integrally formed.

[0053] The following is a specific description of the storage mechanism 1:

[0054] In an alternative embodiment, as Figure 1 and Figure 2 shown, the storage mechanism 1 includes a storage rack 11, a material distribution component 12, and a driving component 13. The storage rack 11 has a material bin 111 for storing a plurality of lower covers 5 stacked, the material distribution component 12 is arranged at the bottom end of the storage rack 11, and the driving component 13 is connected to the material distribution component 12 to drive the material distribution component 12 to selectively switch to the first blocking station or the second blocking station.

[0055] The storage rack 11 may specifically include a plurality of spaced limiting rods, and a material bin 111 is formed between the respective limiting rods.

[0056] When the material taking mechanism 2 takes out the bottom cover 5 in the storage mechanism 1, the driving component 13 drives the material distributing component 12 to switch to the second blocking position. The material distributing component 12 only blocks the cover 5 adjacent to the upper side of the bottom cover 5. The material taking mechanism 2 can smoothly take away the bottom cover 5, and the cover 5 adjacent to the upper side of the bottom cover 5 will not fall off. After the material taking mechanism 2 takes the material, the driving component 13 drives the material distributing component 12 to switch to the first blocking position to block the bottom cover 5 in the bin 111 at this time after the material taking is completed, preventing the bottom cover 5 from falling.

[0057] When the material taking mechanism 2 in the above embodiment takes out the bottom cover 5, the material distributing component 12 can block the cover 5 adjacent to the upper side of the bottom cover 5, which can effectively avoid the phenomenon of taking out multiple covers 5 at a time, avoid waste of the cover 5, make the equipment operation more stable, and improve the product qualification rate.

[0058] In an alternative embodiment, as Figure 4 and Figure 5 shown, the material distributing component 12 includes a material distributing block 121 rotatably connected to the storage rack 11. The rotation axis of the material distributing block 121 extends in the vertical direction. One end of the material distributing block 121 has a pin 1211 extending in the vertical direction, and the other end has a first blocking piece 1212 and a second blocking piece 1213. The first blocking piece 1212 and the second blocking piece 1213 are arranged staggered in the vertical direction.

[0059] In the above embodiment, since the first blocking piece 1212 and the second blocking piece 1213 are arranged staggered in the vertical direction, when the driving component 13 drives the material distributing block 121 to rotate relative to the storage rack 11, the first blocking piece 1212 and the second blocking piece 1213 can alternately block the covers 5 in the bin 111.

[0060] Specifically, in use, as Figure 5As shown, the dowel pin 1211 on the material distribution block 121 extends vertically upward from the top surface of the material distribution block 121, and the first baffle 1212 is located above the second baffle 1213. The driving assembly 13 drives the material distribution assembly 12 to switch to the second blocking station. The first baffle 1212 blocks the lower cover 5 adjacent to the top of the lowermost lower cover 5, and the second baffle 1213 cancels the blocking of the lowermost lower cover 5. The material taking mechanism 2 can smoothly take away the lowermost lower cover 5, and the lower cover 5 adjacent to the top of the lowermost lower cover 5 will not fall off. After the material taking mechanism 2 takes the material, the driving assembly 13 drives the material distribution assembly 12 to switch to the first blocking station. The first baffle 1212 cancels the blocking of the lower cover 5, and the second baffle 1213 rotates to be vertically aligned with the lower cover 5 in the material bin 111. The lower covers 5 in the material bin 111 fall as a whole until the lowermost lower cover 5 contacts the second baffle 1213. When taking material is required, the driving assembly 13 drives the material distribution assembly 12 to switch to the second blocking station again, and so on.

[0061] In an alternative embodiment, as Figure 3 shown, to prevent the storage rack 11 from hindering the movement of the dowel pin 1211, the storage rack 11 has a waist-shaped slot 112 for the dowel pin 1211 to pass through. The waist-shaped slot 112 extends in an arc around the rotation axis of the material distribution block 121 to adapt to the rotation path of the dowel pin 1211.

[0062] In an alternative embodiment, to enable the material distribution block 121 to more stably block the lower cover 5, as Figure 3 shown, a plurality of material distribution blocks 121 are arranged. The plurality of material distribution blocks 121 are evenly spaced around the center of the material bin 111.

[0063] When there are lower covers 5 in the material bin 111, it can also be understood that the plurality of material distribution blocks 121 are evenly spaced around the center of the lower cover 5.

[0064] Specifically, the material distribution block 121 can be configured as two, three, four or five.

[0065] In a preferred embodiment, as Figure 3 shown, the material distribution block 121 is configured as three.

[0066] In an alternative embodiment, as Figure 1 , Figure 3 and Figure 6As shown in the figure, the driving component 13 includes a second driver 131 and a linkage disk 132. The linkage disk 132 is rotationally engaged with a fixed seat 113 at the bottom of the storage rack 11 around the center of the bin 111. A plurality of limiting grooves 1321 are provided on the linkage disk 132, and the plurality of limiting grooves 1321 respectively accommodate the pin shafts 1211 on the plurality of material distribution blocks 121. The power output end of the second driver 131 is rotationally connected to the linkage disk 132, and the second driver 131 is used to drive the linkage disk 132 to rotate relative to the storage rack 11.

[0067] During use, when the second driver 131 drives the linkage disk 132 to rotate a first angle relative to the storage rack 11, the linkage disk 132 drives the pin shafts 1211 on the respective material distribution blocks 121 to act through the limiting grooves 1321 provided thereon, realizing the rotation of the respective material distribution blocks 121 relative to the storage rack 11, and switching the material distribution blocks 121 to the first blocking position. Similarly, when the second driver 131 drives the linkage disk 132 to rotate a second angle relative to the storage rack 11, the linkage disk 132 drives the respective material distribution blocks 121 to switch to the second blocking position.

[0068] It should be noted that the width of the limiting groove 1321 in the circumferential direction can be exactly equal to the outer diameter of the pin shaft 1211, ensuring that when the linkage disk 132 moves, it can drive the pin shaft 1211 to perform corresponding actions in a timely manner.

[0069] The above embodiment is provided with a linkage disk 132, which can realize the synchronous movement of multiple material distribution blocks 121 only through one second driver 131, without setting multiple second drivers 131, reducing the cost of the device.

[0070] It should be noted that any structure that can drive the linkage disk 132 to rotate relative to the storage rack 11 can be the second driver 131 mentioned in the above embodiment. For example: the second driver 131 can be a mechanism that performs linear motion, such as a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0071] In a preferred embodiment, the second driver 131 is a pneumatic cylinder, and the power output end of the second driver 131 can be hinged to the linkage disk 132 through a connecting column 1322 on the linkage disk 132.

[0072] The structure of the material taking mechanism 2 will be specifically described below:

[0073] In an alternative embodiment, as Figure 1 shown, the material taking mechanism 2 includes a third driver 21, a fourth driver 22, and a suction cup 23. The third driver 21 is connected to the suction cup 23, and the third driver 21 is used to drive the suction cup 23 to move in the vertical direction. The fourth driver 22 is connected to the third driver 21, and the fourth driver 22 is used to drive the third driver 21 to turn up and down.

[0074] During use, the third driver 21 drives the suction cup 23 to move upward in the vertical direction, and the suction cup 23 sucks the lower cover 5 at the bottommost end; then the third driver 21 drives the suction cup 23 to move downward in the vertical direction; then the fourth driver 22 drives the third driver 21 to turn downward by 180°; then the third driver 21 drives the suction cup 23 to move downward in the vertical direction, and the suction cup 23 releases the lower cover 5 to the top of the tank body 6; then the fourth driver 22 drives the third driver 21 to turn upward by 180° and continue to pick up materials.

[0075] The above-mentioned material picking mechanism 2 can realize the picking of the lower cover 5 and place the lower cover 5 on the top of the tank body 6, and its structure is simple.

[0076] It should be noted that any structure that can drive the suction cup 23 to move in the vertical direction can be the third driver 21 mentioned in the above embodiments, and any structure that can drive the third driver 21 to turn up and down can be the fourth driver 22 mentioned in the above embodiments. For example: the third driver 21 can be a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc., and the fourth driver 22 can be a rotating motor.

[0077] The structure of the positioning mechanism 3 is specifically described below:

[0078] In an alternative embodiment, as Figure 1 shown, the positioning mechanism 3 includes a limiting member 31 and a fifth driver 32, and the fifth driver 32 is used to press the side wall of the tank body 6 that moves below the material picking mechanism 2 against the limiting member 31.

[0079] When the transportation mechanism transports the tank body 6 below the material picking mechanism 2, the fifth driver 32 acts to press the side wall of the tank body 6 against the limiting member 31 to fix the tank body 6.

[0080] It should be noted that any structure that can press the side wall of the tank body 6 that moves below the material picking mechanism 2 against the limiting member 31 can be the fifth driver 32 mentioned in the above embodiments. For example: the fifth driver 32 can be a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc.

[0081] In a preferred embodiment, the fifth driver 32 is a pneumatic cylinder.

[0082] To increase the contact area between the fifth driver 32 and the tank body 6, the power output end of the fifth driver 32 can have a push block for pressing the tank body 6.

[0083] In an alternative embodiment, as Figure 7 shown, the surface of the push block 321 for contacting the tank body 6 is an arc surface adapted to the outer peripheral surface of the tank body 6, so that the fifth driver 32 can more stably press the tank body 6 against the limiting member 31.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
