Description

Technical Field

[0001] The present invention relates to an automatic bundling device, in particular to a device for gathering, bundling and cutting the stalk part. Background Art

[0002] Among the existing cable tie machines on the market, there are a cable tie conveying mechanism, a cable tie conveying circular track, a cable tie clamping mechanism, a cable tie retracting mechanism and a cable tie heat sealing mechanism. The cable tie passes through the conveying track, clamps the cable tie head, retracts the cable tie, clamps the articles inside the loop with the cable tie, and then seals the opening.

[0003] Both such cable tie machines and sealing machines have the situation that the tightening degree cannot meet the requirements, and they are not applicable to the vast majority of working conditions. Therefore, this work is currently completed manually. The specific reasons are as follows: The cable tie material used in the cable tie machine is a relatively hard material, and the sealing is carried out by heat sealing, and there will be a little distance loosened during sealing, so it cannot be tightened; there is also a method of tying with a rubber rope to tighten, but the rubber rope cannot be pulled too tightly to tie a knot, so it also cannot be tightened.

[0004] Due to the loose bundling of the stalk part, the stalk part will move during subsequent cutting, and there are problems such as burrs, damage and uneven cutting on the cut stalk part.

[0005] In summary, there is a problem in the market that there is a lack of a device for gathering, bundling and cutting the stalk part that can meet the requirements of tightening degree, has a wide range of applicable working conditions and can cut the stalk part neatly. Summary of the Invention

[0037] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0038] like Figures 1 to 7 A stem gathering, bundling and cutting device is shown. First, the device can be used in conjunction with a robot, which grabs scattered plants to the location of the stem gathering, bundling device; the device can also be installed on a three-axis mobile device, which moves the device to the location of the scattered plants.

[0039] S1: The scattered plants are located in the middle area of ​​the gathering mechanism; the two gathering cylinders 50 simultaneously drive the left gathering clamp 51 and the right gathering clamp 52, and the left gathering clamp 51 and the right gathering clamp 52 cross-close to gather the scattered plants in the middle area into bundles.

[0040] S2: The arc-shaped rubber strip guide cylinder 22 extends to push the guide plate 23 to drive the arc-shaped rubber strip guide block 20 to move toward the bundled plants. Finally, the arc-shaped rubber strip guide block 20 is finally buckled on the rubber strip guide frame 10 in the rubber strip guide mechanism. One side opening of the arc-shaped rubber strip guide block 20 after buckling is a rubber strip inlet, which is connected to the outlet of the rubber strip channel 13. The other side opening of the arc-shaped rubber strip guide block 20 is a rubber strip outlet, which is connected to the rubber strip clamping block 12.

[0041] S3: The rubber strip is guided and transmitted through the rubber strip guide mechanism, and the motor 14 drives the driving wheel 15 to rotate through a transmission method such as a belt and a gear box. The driving wheel 15 and the fall wheel 16 are installed in a gap, and the rubber strip enters from the entrance of the rubber strip channel 13. When it contacts the driving wheel 15, the driving wheel 15 guides and pulls the rubber strip into the gap between the driving wheel 15 and the fall wheel 16, and the rubber strip fills the gap. A fall wheel stop block 18 is installed on the outer side of the fall wheel 16. The fall wheel stop block 18 presses the fall wheel 16 to prevent the fall wheel 16 from rotating when the driving wheel 15 stops rotating; the rubber strip is transported by the driving wheel 15 and extends out from the exit of the rubber strip channel 13, and at the same time enters the notch 21 from the rubber strip inlet on the arc-shaped rubber strip guide block 20. The rubber strip continues to move forward and finally extends from the rubber strip outlet on the arc-shaped rubber strip guide block 20 to the location of the rubber strip clamp 12.

[0042] S4: The rubber strip clamping block 12 is driven by the clamping cylinder 17 to move closer to the inner wall of the rubber strip guiding frame 10 to compress the rubber strip. The driving wheel 15 reverses a distance to tighten the rubber strip. The arc-shaped rubber strip guiding cylinder 22 retracts to pull the guide plate 23 to drive the arc-shaped rubber strip guiding block 20 to leave the rubber strip guiding frame 10, and the tightened rubber strip escapes from the slot 21.

[0043] S5: The left rubber strip shrinking push block 30 and the right rubber strip shrinking push block 31 in the nail pressing mechanism are closed toward the middle under the push of the cylinder, squeezing the rubber strip surrounding the stem, so that the two sections of the rubber strip are fitted together, and the fitting position is in the nail pressing groove 32 or above the nail pressing groove 32. The nail in the nail placing frame 33 slides into the nail groove 37 along the nail placing frame 33. The nail pressing cylinder 34 extends out to push the connecting rod 35 to perform a lever movement to squeeze the aluminum nail pressing plate 36 downward. The aluminum nail pressing plate 36 moves downward along the nail groove, pushing the nail to squeeze the rubber strip fitting section, and finally the nail contacts the nail pressing groove 32. The nail is a C-shaped nail, and the two sides of the C-shaped nail are bent and buckled and pressed tightly on the rubber strip fitting section.

[0044] S6: The rubber strip cutter 11 is driven by the cylinder to extend and cut the rubber strip, while the clamping cylinder 17 retracts to drive the rubber strip clamping block 12 to release the rubber strip, and the stalk bundling is now completed.

[0045] The rubber strip is elastic and will rebound after S6 is executed to ensure that the binding force is just right.

[0046] A stem cutting mechanism is installed to meet the need of cutting the stem part. The stem cutting mechanism includes an upper knife 40 as a fixed knife and a lower knife 41 as a movable knife. The upper knife 40 is a V-shaped cutter with the V-shaped opening facing outward. The V-shaped bottom of the V-shaped opening is located below the middle position of the pressure nail groove 32. The upper knife 40 is installed horizontally, and the lower knife 41 is driven by a cylinder to rotate and cooperate with the V-shaped incision of the upper knife 40 to complete the cutting of the plant stem.

[0047] After cutting, the plants are grabbed by a robot and the gathering mechanism releases the bundled plants.

[0048] The cylinder mentioned above is actually used in the actual product, and its function is to drive the connected components to move. It belongs to the power component, and a driving component such as a motor can also be used to complete what the cylinder does; the stalk part includes the stalks of large-leaf crops, flower stalks and some other plant stalks; the rubber strip is a commercially available product with certain elasticity.

[0049] Combined with Figure 1 and Figure 3 , below the folding mechanism in this application is the rubber strip guiding frame 10. The front end of the rubber strip guiding frame 10 is the nail pressing mechanism. The rubber strip contraction push block 30 on the left side and the rubber strip contraction push block 31 on the right side of the nail pressing mechanism are installed on the left and right sides at the front end of the rubber strip guiding frame 10. The nail pressing groove 32 is installed at the middle position between the rubber strip contraction push block 30 on the left side and the rubber strip contraction push block 31 on the right side below the front end of the rubber strip guiding frame 10. The nail pressing cylinder 34, the connecting rod 35 and the aluminum nail pressing plate 36 are all installed above the rubber strip guiding frame 10, and the aluminum nail pressing plate 36 is located directly above the nail pressing groove 32.
