Description

Technical Field

[0001] The invention belongs to the technical field of filling, and in particular relates to a device and method for automatically removing and placing a cover on a paint bucket. Background Art

[0002] With the improvement of production technology, paint filling has basically changed from manual filling to production line filling. Originally, workers first poured paint into the paint bucket, and after filling, closed the bucket of the paint bucket at the opening position, and then used a hammer to manually knock around the bucket cover to make the bucket cover and the opening position of the paint bucket interference fit to achieve closure. However, this method is obviously not compatible with the speed of the filling production line. There are also some equipment for automatic capping, but its capping efficiency is low, the structure of the equipment is relatively complex, and there are certain inconveniences in use, especially for the high accuracy requirements for determining the position of the bucket cover and the barrel body, otherwise it is easy to cause inaccurate cap placement, resulting in unsmooth subsequent capping process, the bucket cover and the barrel body fail to achieve the predetermined sealing installation, and manual re-inspection or manual capping is required. There is also a problem that the barrel body needs to stop for position alignment before placing the cap, resulting in low capping efficiency. Summary of the invention

[0003] In order to overcome the above-mentioned shortcomings, the inventor of the present invention has continuously reformed and innovated through long-term exploration and attempts, multiple experiments and efforts, and proposed a device and method for automatically removing and placing lids for paint buckets. The bucket cover is arranged at an angle, and the bucket cover is placed at an angle at a predetermined position by using the cooperation of a suction cup and a rotating device. At this time, the filled paint bucket is continuously conveyed forward by a conveyor belt, and directly drives the bucket cover forward after contacting the bucket cover, so that the paint bucket does not need to pause when it falls on the bucket cover on the conveyor belt, and can achieve uninterrupted and continuous lid dropping. With the automatic lid-replenishing function of the lid storage mechanism, long-term continuous lid dropping can be achieved. The bucket cover is placed at an angle at a predetermined position, and the inner edge of the bucket cover coincides with the outer edge of the paint bucket to achieve positioning. The positioning is accurate and no other sensors are required to achieve alignment between the bucket cover and the barrel body. The structure is simple and practical.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is to provide a device for automatically taking and placing covers on a paint bucket.

[0009] According to the automatic cover removal and placement device and method for paint buckets described in the present invention, a further preferred technical solution is: a cover-replenishing cylinder is arranged on the side of the bracket, and the cover-replenishing cylinder is located at the rear end of the stacked bucket covers arranged in a single row, and is used to push the stacked bucket covers to the front end of the anti-falling bracket. The cover-replenishing cylinder cooperates with the cover-replenishing detection sensor to realize automatic cover-replenishing after the front bucket cover is exhausted.

[0010] According to the device and method for automatically removing and placing a cover on a paint bucket described in the present invention, a further preferred technical solution is that the suction cup device adopts a rubber disc, and a pressure relief valve is arranged on the rubber disc.

[0011] A method for automatically removing and placing a cover on a paint bucket comprises the following steps: S1, a filled paint bucket is conveyed at a uniform speed from an inlet to an outlet by a conveyor belt at uniform intervals; S2, when two barrels pass through, the cover suction and release mechanism rotates, the empty lower end suction cup rotates to the upper end to take the barrel cover again, and the upper end suction cup with the barrel cover sucked rotates to the lower end, and the suction cup adjusts the pressure to prepare for the cover release; S3, the bucket cover is deflected toward the side of the paint bucket that is not covered, so that the high side of the bucket cover is higher than the edge of the bucket, and the low side of the bucket cover is lower than the edge of the bucket cover; S4, the unclosed paint bucket moves towards the bucket cover that is ready to be closed under the drive of the conveyor belt, the bucket edge contacts the bucket cover, and when the front bucket edge moves to the lowest side of the bucket cover, the inner edge of the bucket cover coincides with the outer edge of the paint bucket, and at this time, the bucket cover and the bucket body are at the position where they need to coincide when the cover is closed; S5, the bucket cover is driven by the bucket and separated from the suction cup, and the bucket cover falls and covers the bucket body, at which time the bucket cover overlaps with the bucket body and the groove of the bucket cover overlaps with the bucket edge of the paint bucket when the cover is closed; at which time the bucket cover overlaps with the bucket body and the groove of the bucket cover overlaps with the bucket edge of the paint bucket when the cover is closed; S6, the barrel cover after the cover is dropped is pressed onto the barrel body by the subsequent cover pressing mechanism.

[0012] According to the device and method for automatically removing and placing covers on paint buckets described in the present invention, a further preferred technical solution is: in step S3, the tilt angle is 3-10°.

[0022] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. Therefore, the detailed description of the embodiments of the present invention provided below is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention.

[0023] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0024] Embodiment 1: like Figure 1As shown, a device for automatically taking and placing covers for a paint bucket. It includes a bucket feeding mechanism 1, a cover sucking and placing mechanism 2, and a cover storage mechanism 3. The cover sucking and placing mechanism is arranged above the conveying line of the bucket feeding mechanism 1, and the cover storage mechanism 3 is arranged above the cover sucking and placing mechanism. The cover sucking and placing mechanism 2 includes a suction cup device 201, a lifting device 202, and a rotating device 203. Two suction cup devices 201 are respectively installed on the lifting device 202 and then relatively installed on the rotating device 203 (relatively here means relatively installed at 180°, and it can also be other structures such as three suction cups). The cover placement position of the suction cup device 201 is offset to the side of the conveying line entering the bucket so that it has an angle in the vertical direction, and the offset angle is 3°-10°. At this time, one side of the bucket cover 4 is high and the other side is low, and the high side is located in the direction of the bucket feeding. It should be noted that the offset of the suction cup device 201 is the offset in the direction of the bucket feeding, and it shall not be offset in other directions. At the same time, a cover removal detection sensing device 204 is set to confirm the correctness of the cover removal.

[0025] The barrel feeding mechanism 1 comprises a bracket 101 and a conveyor belt 102. The conveyor belt 102 is mounted on the bracket 101. A barrel feeding sensor 103 is mounted on the front end of the bracket 101. A barrel discharging sensor 104 is mounted on the rear end of the bracket 101. The cap sucking and placing mechanism 2 is located on the bracket 101 between the barrel feeding sensor 103 and the barrel discharging sensor 104. A barrel positioning sensor 105 is arranged at a position corresponding to the position of the cap sucking and placing mechanism 2. The barrel positioning sensor 105 is mainly used to determine the barrel position and form a signal feedback, so that the cap sucking and placing mechanism 2 can rotate and take the cap during the gap after the barrel passes. Of course, the way of taking the cap does not necessarily rely on rotation. Other reasonable ways can also be used, such as a robot, etc. The bottom of the bracket 101 is provided with a horizontally adjustable support foot 1011, which is used to install and level the entire device, ensure the level of the conveyor belt 102, and prevent the paint bucket from tilting. It is also used to suspend and level the entire device. The main purpose of leveling is to ensure that the filled paint bucket can be transported smoothly without tilting, ensure good cooperation with the bucket cover 4, and achieve stable cover placement.

[0026] The cover storage mechanism 3 includes an anti-falling bracket 301, a cover blocking device 302, and a top cover device 305. The top cover device 305 is arranged below the anti-falling bracket 301, and the cover blocking device 302 is arranged at the bottom of the top cover device 305. The barrel covers 4 are stacked and placed in the anti-falling bracket 301. The anti-falling bracket 301 is mainly used to limit the column formed by the barrel covers to ensure that they do not fall after stacking. Under the action of the top cover device 305, the barrel covers 4 can be restricted from falling, and the barrel covers are restricted from falling by cooperating with the cover blocking device 302, so that the suction cup 2011 absorbs one barrel cover 4 at a time. The principle is relatively simple, that is, the falling of the barrel covers is controlled to release only one barrel cover at a time, first clamped and then blocked from falling by the cover blocking device 302. After the suction cup absorbs, the cover blocking device 302 withdraws to release the barrel cover, which will not be repeated here.

[0027] A covering cylinder 303 is provided on the side of the bracket 101. The covering cylinder 303 is located at the rear end of the stacked barrel covers arranged in a single row, and is used to push the stacked barrel covers to the front end of the anti-falling bracket 301. The covering cylinder 303 cooperates with the covering detection sensor 304 to realize automatic covering after the barrel covers at the front end are exhausted. That is, after detecting that the barrel covers at the front are used up, the covering cylinder 303 at the rear end is used to push the barrel covers stacked at the rear end to the front end to realize the replenishment of the barrel covers. This principle is relatively simple and can be easily realized. Other similar structures can also be adopted.

[0028] The suction cup device 201 adopts a rubber disc, and a pressure relief valve 2012 is arranged on the rubber disc. The pressure relief valve 2012 is mainly used for adjusting the pressure, so that the suction force of the suction cup 2011 can be changed as needed and will not fall off when rotating. Then the pressure is released so that the barrel body 5 can drive the barrel cover to detach.

[0029] Embodiment 2: A method for automatically removing and placing a cover on a paint bucket, the steps of which include: S1, the filled paint bucket is conveyed at a uniform speed from an inlet to an outlet by a conveyor belt 102 at uniform intervals; S2, when two barrels pass through, the cover sucking and placing mechanism 2 rotates, the empty lower end suction cup 2011 rotates to the upper end to re-take the barrel cover, and the upper end suction cup with the barrel cover sucked rotates to the lower end, so as to realize the recycling of the barrel cover. Of course, this is only a relatively simple rotary cover taking mechanism, and other reasonable mechanisms can also be used as long as the principle is reasonable; S3, the bucket cover is deflected to the side of the paint bucket that is not covered (the deflection action can be together with step S2, or it can be a separate deflection action, which can be set as needed and no longer described, here refers to the position state of the bucket cover), so that the high side of the bucket cover is higher than the edge of the bucket, and the low side of the bucket cover is lower than the edge of the bucket cover, and the suction cup is pressure-adjusted to prepare for the lid to be placed, that is, the pressure is reduced, so that the bucket cover can be separated under the dragging of the bucket body. Whether to use partial pressure relief or to completely relieve pressure directly after being dragged can be designed by yourself, which is not the focus of the present invention; S4, the unclosed paint bucket moves towards the bucket cover 4 that is ready for closing under the drive of the conveyor belt 102, the bucket edge contacts the bucket cover 4, and when the front bucket edge moves to the lowest side of the bucket cover, the inner edge of the bucket cover coincides with the outer edge of the paint bucket. At this time, the bucket cover and the barrel body 5 are at the position that needs to be overlapped when closing the cover. Of course, this means that the contact position is already at the required overlapping position. Since the bucket cover has an annular groove for accommodating the bucket edge for closing the cover, the position that needs to be overlapped at this time refers to an approximate position, which may not be completely accurate. S5, the bucket cover is separated from the suction cup under the drive of the bucket, and the bucket cover falls and covers the bucket body. At this time, the bucket cover overlaps with the bucket body and the groove of the bucket cover overlaps with the bucket edge of the paint bucket when the cover is closed. The bucket cover moves forward under the drive of the bucket. The forward movement here refers to a very small distance, that is, the suction cup has a little elastic space. After exceeding the limit, the bucket cover will be separated and fall a small distance under gravity. At this time, the bucket cover 4 overlaps with the bucket body 5 and the groove of the bucket cover overlaps with the bucket edge of the paint bucket when the cover is closed, and is ready to be pressed.

[0030] S6, the barrel cover after the cover is dropped is pressed onto the barrel body by the subsequent pressing mechanism, and the structure of the pressing mechanism can be set as required.

[0031] In step S3, the inclination angle is 3°-10°, which can be set according to the specific structure of the barrel body and the barrel cover. It should be noted that the barrel cover of the present invention is a barrel cover with a cover edge, which is commonly found in plastic lubricating oil barrels and paint barrels.

[0032] The high side of the barrel cover is 2cm-5cm away from the barrel body, and the low side is 2-3cm lower than the bottom edge of the barrel. This distance can be adjusted according to the on-site details. Without affecting normal operation, this distance should be as small as possible.
