Description

Technical Field

[0001] The invention relates to the field of palletizing equipment, in particular to a starch packaged finished product conveying and palletizing equipment. Background Art

[0002] Starch is a high-molecular carbohydrate, a polysaccharide composed of glucose molecules. Starch is generally placed in woven bags during production, and then the starch bags are neatly and automatically stacked on pallets by palletizing robots.

[0003] When stacking starch woven bags, existing palletizing robots generally use multiple rows of grabbing teeth to grab the starch woven bags, which makes it easy for the starch inside the woven bags to flow to the gaps between the grabbing teeth under the action of gravity, so that the woven bags are wrapped around the outside of the grabbing teeth under the drive of the starch, resulting in an increase in the contact area between the grabbing teeth and the starch woven bags, thereby increasing the friction between the grabbing teeth and the starch woven bags. When the grabbing teeth are opened to stack the starch woven bags, the grabbing teeth and the starch woven bags rub quickly, which can easily cause the starch woven bags to rupture and cause starch leakage. In addition, the existing palletizing robots can only release the starch woven bags at a certain height from the stacking position, causing the starch woven bags to fall to the stacking position under the action of gravity, which can easily cause the starch inside the starch woven bags to leak out and fly.

[0015] 1. The present invention adopts an arc-shaped grab plate to grab the starch woven bag. The arc-shaped grab plate supports the grabbed starch woven bag through the roller on its inner side, so that the starch woven bag and the roller are in rolling contact, thereby reducing the friction between the starch woven bag and the arc-shaped grab plate, thereby avoiding the arc-shaped grab plate from scratching the starch woven bag, and the arc-shaped grab plate can be in rolling contact with the stacked starch woven bags through the roller on its outer side, thereby avoiding the arc-shaped grab plate from scratching the stacked starch woven bags and avoiding the phenomenon of starch leakage.

[0017] 3. The present invention adopts a mechanical arm to drive the outer roller of the arc-shaped grab plate to press against the upper part of the uppermost starch woven bag or pallet, and then drives the arc-shaped grab plate to rotate through the rotating component, so that the arc-shaped grab plate gradually places the starch woven bag on the upper part of the uppermost starch woven bag or pallet from the middle of the starch woven bag to both sides, thereby completing the stacking of the starch woven bag, thereby avoiding the starch woven bag from falling, reducing the degree of starch leakage and flying inside the starch woven bag, and ensuring production safety.

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product specifications are used.

[0032] See also Figure 1 and Figure 2 A starch packaged finished product conveying and palletizing device comprises a mechanical arm 1, an L-shaped plate 2 is fixedly installed on the upper left side of the mechanical arm 1, a mounting frame 4 is fixedly connected to the lower part of the L-shaped plate 2, the mounting frame 4 has a cross-shaped upper half structure, a grabbing mechanism 5 for grabbing starch woven bags is arranged on the mounting frame 4, and a dust suppression mechanism 6 for preventing starch from flying is arranged on the mounting frame 4.

[0033] When the starch woven bags need to be stacked, the robot arm 1 first drives the mounting frame 4 to move to the upper part of the production line through the L-shaped plate 2, and then the starch woven bags on the production line are supported by the grabbing mechanism 5, and then the starch woven bags are driven by the robot arm 1 to move to the stacking area. During the movement, the starch woven bags are covered by the dust suppression mechanism 6, and then the starch woven bags are stacked in the stacking area by the grabbing mechanism 5, and then the starch woven bags are trimmed again by the dust suppression mechanism 6, so that the placement of the starch woven bags is more stable.

[0034] See also Figure 2 and Figure 3 The grabbing mechanism 5 includes a plurality of groups of arc-shaped grab plates 51 which are evenly spaced along the front-to-back direction on the mounting frame 4. Each group of arc-shaped grab plates 51 is composed of two arc-shaped grab plates 51 which are symmetrically arranged on the left and right. The two arc-shaped grab plates 51 in the same group are staggered in the front and back. The arc-shaped grab plates 51 are rotatably connected to the mounting frame 4. Rollers 52 are rotatably arranged on the outer side of the arc-shaped grab plates 51 along their tracks at equal intervals. A rotating component 53 for driving the arc-shaped grab plates 51 to rotate is arranged on the mounting frame 4.

[0035] See also Figure 2 , Figure 3 and Figure 4 The rotating assembly 53 includes an arc-shaped toothed plate 531 fixedly mounted on one side of two arc-shaped grab plates 51 in the same group close to each other, and the arc-shaped toothed plate 531 is located at the upper position of the arc-shaped grab plates 51. A plurality of groups of driving gears 532 corresponding to each group of arc-shaped grab plates 51 are arranged at equal intervals in the front-to-back direction on the mounting frame 4. Each group of driving gears 532 is composed of driving gears 532 arranged at equal intervals along the circumference of the arc-shaped grab plates 51 on the mounting frame 4. The driving gears 532 are meshed with the arc-shaped toothed plate 531 rotated to its position, and a synchronizing portion 533 for driving all driving gears 532 to rotate synchronously is arranged on the mounting frame 4.

[0036] See also Figure 3 and Figure 4 The synchronization part 533 includes a transmission rod 5331 fixedly installed inside the driving gear 532, and a driven bevel gear 5332 is fixedly installed at one end of the transmission rod 5331 close to the center of the mounting frame 4. Driving bevel gears 5333 are rotatably arranged at equal intervals along the front-to-back direction inside the mounting frame 4. The driving bevel gears 5333 are meshed with the driven bevel gears 5332 at the corresponding positions, and a rotating shaft 5334 is fixedly installed on the axial position of the driving bevel gear 5333. An execution motor 5335 is fixedly installed on the rear side of the mounting frame 4, and the output shaft of the execution motor 5335 is fixedly connected to the rotating shaft 5334.

[0037] When the robot arm 1 moves the mounting frame 4 to the upper part of the starch woven bag on the production line, the execution motor 5335 is started to drive the rotating shaft 5334 to rotate, and the rotating shaft 5334 drives all the active bevel gears 5333 to rotate, and the active bevel gear 5333 drives the driven bevel gear 5332 meshing with it to rotate, and the driven bevel gear 5332 drives the active gear 532 at the corresponding position to rotate through the transmission rod 5331, and the active gear 532 drives the two arc-shaped grab plates 51 in the same group to rotate in opposite directions through the arc-shaped tooth plate 531, so that the lower ends of the two arc-shaped grab plates 51 in the same group are close to each other and staggered, so that the lower part of the arc-shaped grab plates 51 moves to the lower part of the starch woven bag on the production line.

[0038] See also Figure 2 and Figure 5 The grabbing mechanism 5 also includes a supporting assembly 54 arranged on the arc-shaped grab plate 51, and the supporting assembly 54 includes a group of connecting plates 541 hinged on the side of two adjacent arc-shaped grab plates 51 close to each other, and each group of connecting plates 541 is composed of four connecting plates 541 arranged in a rectangular shape at the lower part of the arc-shaped grab plate 51, and one end of each group of connecting plates 541 away from the arc-shaped grab plate 51 at the corresponding position is hinged to a moving frame 542, and supporting wheels 543 are rotatably arranged on the moving frame 542 along its length direction at equal intervals, and a No. 1 hydraulic rod 544 is hinged between the moving frame 542 and the arc-shaped grab plate 51.

[0039] When the lower part of the arc-shaped gripping plate 51 moves to the lower part of the starch woven bag on the production line, the mounting frame 4 is lifted by the mechanical arm 1, so that the mounting frame 4 lifts the starch woven bag on the production line to the upper part of the production line through the arc-shaped gripping plate 51. When the lower part of the arc-shaped gripping plate 51 is completely moved to the upper side of the production line, the telescopic section of the No. 1 hydraulic rod 544 is extended to push the moving frame 542. Since the arc-shaped gripping plate 51, the connecting plate 541 and the moving frame 542 form a parallelogram structure, the moving frame 542 drives the supporting wheel 543 thereon to move upward while maintaining a state parallel to the arc-shaped gripping plate 51, so that the supporting wheel 543 moves to the gap between two adjacent arc-shaped gripping plates 51, and at the same time, the supporting wheel 543 supports the part of the starch woven bag located in the gap between the two arc-shaped gripping plates 51, thereby preventing the starch inside the woven bag from flowing into the gap between the arc-shaped gripping plates 51.

[0040] See also Figure 1 and Figure 2 The dust suppression mechanism 6 includes a closed cover 61 which is slidably arranged on the outside of the mounting frame 4, an electric push rod 62 is fixedly installed on the upper part of the closed cover 61, and the telescopic section of the electric push rod 62 is fixedly connected to the mounting frame 4. A bellows 63 is fixedly installed on the left side of the upper part of the closed cover 61, and the bellows 63 is connected to the collection device. An exhaust fan 64 is fixedly installed at a position corresponding to the bellows 63 inside the closed cover 61.

[0041] When the lower part of the arc-shaped grab plate 51 is completely moved to the upper side of the production line, the telescopic section of the electric push rod 62 is extended to drive the closed cover 61 to move downward relative to the mounting frame 4, so that the lower side of the closed cover 61 moves to the lower part of the arc-shaped grab plate 51, so that the closed cover 61 covers the starch woven bag therein, and at the same time, the exhaust fan 64 is turned on, so that the exhaust fan 64 continuously attracts the flying starch in the air inside the closed cover 61 into the bellows 63, and at the same time, the flying starch flows through the bellows 63 to the inside of the collecting device, thereby collecting the flying starch.

[0042] It should be noted that the collection device in this embodiment adopts the dust collector in the prior art.

[0043] See also Figure 2 , Figure 6 and Figure 7 The dust suppression mechanism 6 also includes a shaping component 65 arranged at the lower part of the mounting frame 4. The shaping component 65 includes a movable plate 651 arranged at the lower part of the mounting frame 4 and sliding up and down through a guide column. A second hydraulic rod 652 is fixedly installed between the movable plate 651 and the mounting frame 4. A trapezoidal block 653 is fixedly installed at the lower center position of the movable plate 651.

[0044] When the lower part of the arc-shaped gripping plate 51 is completely moved to the upper side of the production line, the telescopic section of the No. 2 hydraulic rod 652 is extended to drive the movable plate 651 to move downward relative to the mounting frame 4, so that the movable plate 651 drives the trapezoidal block 653 to be squeezed on the upper middle side of the starch woven bag. On the one hand, the starch woven bag can be limited by the squeezing of the trapezoidal block 653 to prevent the starch woven bag and the arc-shaped gripping plate 51 from moving relative to each other when the mounting frame 4 moves, thereby causing the stacking position of the starch woven bag to deviate. On the other hand, since the inner side surface of the arc-shaped gripping plate 51 is an arc-shaped structure, when the arc-shaped gripping plate 51 supports the starch woven bag, the two sides of the starch woven bag are higher than the middle part, which makes it easy for the starch inside the woven bag to flow to the middle part of the woven bag, resulting in uneven distribution of the starch inside the starch woven bag, which can easily cause the starch woven bag to fall over when it is stacked. The squeezing of the trapezoidal block 653 can prevent the starch inside the woven bag from flowing to the middle part of the woven bag.

[0045] Afterwards, the robot arm 1 drives the starch woven bags to the stacking position through the arc-shaped gripping plate 51, so that the roller 52 on the outer side of the arc-shaped gripping plate 51 rests against the upper part of the topmost starch woven bags or the pallet, and then the reverse execution motor 5335 drives the lower parts of the two arc-shaped gripping plates 51 in the same group to move away from each other, so that the arc-shaped gripping plate 51 gradually stacks the starch woven bags from the middle to the sides on the upper part of the topmost starch woven bags or the pallet, so that the starch woven bags gradually roll and slide off the arc-shaped gripping plate 51, thereby avoiding the starch woven bags from falling, reducing the degree of starch leakage and flying inside the starch woven bags, and ensuring production safety.

[0046] At the same time, the rolling contact between the roller 52 and the starch woven bag reduces the friction between the starch woven bag and the arc-shaped gripping plate 51, thereby preventing the arc-shaped gripping plate 51 from scratching the starch woven bag. The arc-shaped gripping plate 51 can make rolling contact with the stacked starch woven bags through the roller 52 on its outer side, thereby preventing the arc-shaped gripping plate 51 from scratching the stacked starch woven bags and preventing starch leakage.

[0047] See also Figure 2 , Figure 6 , Figure 7 and Figure 8The shaping component 65 also includes notch plates 654 symmetrically arranged on the front and rear sides of the trapezoidal block 653. The notch plates 654 are fixedly connected to the trapezoidal block 653. The side of the notch plate 654 away from the trapezoidal block 653 is in a horizontal structure, and the side of the notch plate 654 close to the trapezoidal block 653 is in a structure inclined toward the upper part close to the center of the movable plate 651. Rolling rollers 655 are arranged inside the front and rear notch plates 654 along their tracks. The rolling rollers 655 cooperate with the notches of the notch plates 654. The inside of the rolling rollers 655 is a hollow structure. Through holes are opened at equal intervals on the outside of the rolling rollers 655. The rear side of the rolling rollers 655 is connected to the bellows 63 through a hose. The mounting frame 4 is provided with a power unit 656 for driving the rolling rollers 655 to move.

[0048] See also Figure 2 and Figure 6 The power unit 656 includes a bidirectional screw 6561 rotatably arranged on the front side of the mounting frame 4, a power motor 6562 is fixedly installed on the right front side of the mounting frame 4, the output shaft of the power motor 6562 is fixedly connected to the bidirectional screw 6561, a sliding plate 6563 symmetrically arranged on the front side of the mounting frame 4 and connected to it for left-right sliding movement, a follower plate 6564 symmetrically arranged on the front side of the moving plate 651 and connected to it for left-right sliding movement, the sliding plate 6563 is slidably connected to the follower plate 6564 at the corresponding position up and down, and the follower plate 6564 cooperates with the notch of the rolling roller 655 through the vertical notch at the lower part thereof.

[0049] When the arc-shaped grab plate 51 rotates to the initial position, the starch woven bag completely slides from the arc-shaped grab plate 51 to the upper part of the uppermost starch woven bag or the tray. At this time, the trapezoidal block 653 is still pressed on the upper middle side of the starch woven bag. Then, the power motor 6562 is started to drive the bidirectional screw 6561 to rotate, so that the bidirectional screw 6561 drives the follower plate 6564 to move away from the trapezoidal block 653 through the sliding plate 6563, and the follower plate 6564 drives the rolling roller 655 to move downward along the inclined structure of the notch plate 654 until it rests on the starch woven bag. Then, the follower plate 6564 drives the rolling roller 655 to move along the horizontal structure of the notch plate 654 away from the trapezoidal block 653, so that the rolling roller 655 rolls the starch woven bag.

[0050] By rolling the starch inside the starch woven bag toward the push rod through the rolling roller 655, the starch inside the starch woven bag can be evenly distributed, thereby increasing the stability of the starch woven bag stacking. Secondly, the starch inside the starch woven bag can be rolled and compacted to prevent the starch from flowing inside the woven bag, thereby further increasing the stability of the starch woven bag stacking.

[0051] When rolling the starch woven bag, the rolling roller 655 can also absorb the overflowed starch on the surface of the starch woven bag through the through holes thereon, so that the overflowed starch flows along the rolling roller 655 and the hose to the inside of the corrugated tube 63, and finally the overflowed starch flows from the corrugated tube 63 to the inside of the collecting device, thereby reducing the amount of starch on the surface of the starch woven bag, thereby increasing the friction between the upper and lower layers of starch woven bags, and making the stacking of the starch woven bags more stable.

[0052] See also Figure 6 and Fig. 9 The shaping component 65 also includes a hammering part 657 arranged inside the trapezoidal block 653, and the hammering part 657 includes a hammering plate 6571 arranged inside the trapezoidal block 653 for sliding up and down. A pushing spring is arranged between the hammering plate 6571 and the trapezoidal block 653. A fixed column 6572 is fixedly installed on one side of the upper part of the hammering plate 6571 through a support plate. A rotating disk 6573 is rotatably arranged inside the trapezoidal block 653, and a protruding block is fixedly installed on the upper side of the rotating disk 6573. A rotating motor 6574 is fixedly installed on the upper part of the moving plate 651, and the output shaft of the rotating motor 6574 is fixedly connected to the rotating disk 6573.

[0053] When the rolling roller 655 rolls the starch woven bag, the rotating motor 6574 is started to drive the rotating disk 6573 to rotate, so that the rotating disk 6573 intermittently pushes the fixed column 6572 upward through the raised block thereon, and the fixed column 6572 drives the hammer plate 6571 to move upward intermittently through the support plate. When the raised block rotates to no longer contact the fixed column 6572, the rebound force of the push spring pushes the hammer plate 6571 to hit the middle position of the starch woven bag, so that the hammer plate 6571 hammers the starch in the middle of the starch woven bag to make it compact, thereby further increasing the stability of the stacking of the starch woven bags.

[0054] When stacking starch woven bags, the present invention also includes the following steps: In the first step, the robot arm 1 drives the mounting frame 4 to move to the upper part of the production line through the L-shaped plate 2, and starts the execution motor 5335 to drive the two arc-shaped grab plates 51 in the same group to rotate in opposite directions, so that the lower part of the arc-shaped grab plates 51 moves to the lower part of the starch woven bags on the production line, and the lifting robot arm 1 lifts the starch woven bags on the production line to the upper part of the production line.

[0055] In the second step, the telescopic section of the No. 1 hydraulic rod 544 is extended to push the movable frame 542 to move to the gap between two adjacent arc-shaped grab plates 51, and at the same time, the supporting wheel 543 supports the starch woven bag in the gap between the two arc-shaped grab plates 51 to prevent the starch inside the woven bag from flowing into the gap between the arc-shaped grab plates 51.

[0056] The third step is to extend the telescopic section of the electric push rod 62 to drive the closed cover 61 to place the starch woven bag cover inside it, and at the same time turn on the exhaust fan 64, so that the exhaust fan 64 can continuously attract the flying starch in the air inside the closed cover 61 into the bellows 63, and at the same time make the flying starch flow through the bellows 63 to the inside of the collection device, so as to collect the flying starch.

[0057] The fourth step is to extend the telescopic section of the second hydraulic rod 652 to drive the trapezoidal block 653 to squeeze the upper middle side of the starch woven bag. On the one hand, the starch woven bag can be limited by the squeezing of the trapezoidal block 653, and on the other hand, the starch inside the woven bag is prevented from flowing to the middle of the woven bag, resulting in uneven distribution of starch inside the starch woven bag.

[0058] In the fifth step, the robot arm 1 drives the starch woven bags to the stacking position through the arc-shaped gripping plate 51, and the reverse execution motor 5335 gradually stacks the starch woven bags from the middle to both sides on the top layer of starch woven bags or the upper part of the pallet to avoid falling of the starch woven bags and preventing the arc-shaped gripping plate 51 from scratching the starch woven bags.

[0059] The sixth step is to start the power motor 6562 to drive the rolling roller 655 to roll the starch woven bag, so that the starch inside the starch woven bag is evenly distributed, thereby increasing the stability of the starch woven bag stacking. The starch inside the starch woven bag can also be rolled and compacted to prevent the starch from flowing inside the woven bag, thereby further increasing the stability of the starch woven bag stacking.

[0060] The seventh step is to start the rotating motor 6574 to drive the rotating disk 6573 to rotate. The rotating disk 6573 cooperates with the push spring through the protrusion block thereon, so that the hammer plate 6571 continuously hits the middle position of the starch woven bag, so that the hammer plate 6571 hammers the starch in the middle of the starch woven bag to make it compact, thereby further increasing the stability of the starch woven bag stacking.
