Strapping machine and method of using the same

Abstract

The present invention discloses a strapping machine and a strapping method thereof, in particular, a strapping machine for bundling strip-shaped objects together or into small bundles. The strapping machine comprises a base frame, a main arm, a rope releasing part, a rope holding part, a rope tying part, a supporting part, a hoop part, and a transmission part. The strapping machine uses a strapping rope to wrap around the bundled object, and at the same time uses a hoop material to hoop the joint of the strapping rope wrapped around the bundled object to form a closed rope loop to achieve its bundling. It replaces the traditional manual bundling, and makes the bundling process of strip-shaped objects in daily production and life semi-automatic, and it only takes about 1 second to complete the bundling; the bundling is standardized, highly standardized, fast, beautiful, safe, and practical, and effectively reduces the production cost. It is particularly suitable for agricultural production to fix the branches and vines of crop plants such as tomatoes, cucumbers, and grapes; in addition, it can also be applied to the bundling and bundling needs required in various links such as the production, transportation, warehousing, and sales of strip-shaped vegetables and other foods and strip-shaped non-food products.

Description

Technical Field

[0001] The present invention relates to a baling machine and a baling method which can be applied to agricultural production, storage, sales and other links as well as daily life production fields, in particular to a baling machine and a baling method which can bundle strip-shaped objects together or bundle them into small bundles. Background Art

[0002] When planting crops such as tomatoes, cucumbers, beans, peppers, grapes, and kiwis, we usually need to fix the vines or branches of the plants to guide their growth or help them bear fruit, so as to improve crop yield and quality. The traditional solution is to fix them manually by tying them one by one with ropes or cloth strips. A more advanced method is to use tools such as a branch tying machine to tie the plants.

[0003] For example, an invention patent with application publication number CN103025148A discloses a horticultural branch binding machine, which relates to a horticultural branch binding machine technology for binding branches to pillars and guide ropes in order to make horticultural crops or agricultural crops grow well, and relates to a horticultural branch binding machine composed of a machine base, a guide belt groove, a cone, a rocker arm, a machine head, and a connecting rod, wherein the cone includes: a cone frame equipped with a cover and a bracket groove on one side; an adhesive heating wire unit having an adhesive heating wire that obtains a certain current from a power supply device; and a bracket that can detach the adhesive heating wire unit and is inserted into the bracket groove; the adhesive heating wire is opposite to the clamp, and the two ends of the binding tape introduced between the adhesive heating wire and the clamp are heated and bonded.

[0004] However, although the efficiency of the common strapping machine has been improved, it still has the inherent defect of using straps to strap, which actually forms a loose ring on the strapped object, making it impossible to tie tightly, and the strapping has poor load-bearing capacity and is easy to break.

[0005] Also, in the process of vegetable harvesting and marketing, strip vegetables need to be bundled into small bundles for storage, transportation and sales. Or in daily life and production, when non-food strip items are bundled, the current practice is to bundle them by manual tying or tape bundling. On the one hand, the workload is large, the efficiency is low, the cost is high, and the bundling is not standardized, the feel is rough, and the degree of standardization is low. On the other hand, if tape is used for bundling, it is easy to cause harmful residues such as adhesives. Traditional bundling machines cannot solve the above problems because of their inherent defect of not being able to bundle tightly. Summary of the invention

[0006] In view of the above problems, the object of the present invention is to provide a strapping machine and a strapping method with more reliable strapping and wider application scenarios. The strapping machine and a strapping method have the characteristics of high efficiency, low cost, standardized strapping, appropriate and adjustable tightness of strapping, not easy to cause damage to the strapped objects, good load-bearing capacity, high degree of standardization, and wide application scenarios.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] Strapping machine and strapping method:

[0009] The strapping machine has:

[0010] A base frame; a main arm disposed on the base frame and rotatable around a first fulcrum; a rope releasing portion disposed on the base frame and releasing the tying rope in a constrained manner; a rope holding portion disposed on the main arm and holding the end of the tying rope released from the rope releasing portion; a tied object guided between the base frame and the main arm is tied by the tying rope stretched between the base frame and the main arm, characterized in that:

[0011] The strapping machine has a tying mechanism for tying the butted parts of the tying rope by the cooperation of a rope tying part provided on the main arm, a supporting part provided on the base frame, a tying part provided on the base frame, and a conveying part provided on the base frame for conveying tying materials.

[0012] The strapping method is applied to the strapping machine provided by the present invention:

[0013] The rope end of the tying rope released from the rope releasing portion is held and pulled out by the rope holding portion, thereby forming a straightened tying rope section between the rope holding portion and the rope releasing portion;

[0014] The tied object is guided to the tying rope segment so that the tying rope segment passes around the tied object, and then the two ends of the tying rope segment, i.e., the butt joints, are constrained together by the rope binding portion and pressed to the supporting portion, while the hoop portion hoop together the two ends of the tying rope segment constrained together, i.e., the butt joints, to form a closed rope loop wrapped around the tied object, thereby completing the tying.

[0015] In this way, it can be ensured that the closed binding rope loop formed for binding fits on the bound object, the binding is more solid and reliable, the load-bearing capacity is better, and the application scenarios are also more extensive. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] like Figure 2 As shown: the strapping machine base frame 01 and the main arm 02 extend rightward and downward from the first pin shaft 11 (first fulcrum) to form a pair of handles 011 and 021 respectively. By holding the pair of handles 011 and 021, the main arm 02 can be driven to rotate counterclockwise around the first pin shaft 11 (first fulcrum), and the strapping machine changes from an open state to a closed state; in addition, a spring (omitted in the view) applies force between the base frame 01 and the main arm 02. When the pair of handles 011 and 021 are released, the main arm 02 rotates clockwise relative to the base frame 01 to return to the initial state (open state).

[0033] A receiving portion 9 is provided at the rear of the handle 011 and is composed of a first receiving component 91 located below the handle 011 for receiving the binding rope and a second receiving component 92 located above the handle 011 for receiving the hoop material.

[0034] The rope releasing part 3 located at the front of the base frame 01 includes a curved rod 31 (first rope guiding part) arranged on one side of the front of the base frame 01, and a rope guiding hole 32 (second rope guiding part) located at the front end of the base frame 01 and oriented perpendicular to the plane of the rotation trajectory of the main arm 02 around the first pin shaft 11 (first fulcrum); wherein the curved rod 31 (first rope guiding part) forms a certain angle with the side of the base frame 01, and the rear end of the curved rod 31 (first rope guiding part) is fixed to the side of the base frame 01, so that the front part of the curved rod 31 (first rope guiding part) forms a certain gap with the front side of the base frame 01 (omitted in the view), and the adjustable screw arranged on the front side of the base frame 01 and pressing the front end of the curved rod 31 (first rope guiding part) is rotated. The wire 33 can adjust the size of the gap (view omitted) between the front of the curved rod 31 (first guide rope component) and the front side of the base frame 01; the binding rope led out from the first receiving component 91 passes through the holes (view omitted) preset in the handle 011 and the lower part of the base frame 01 and the front side of the base frame 01, reaches the front of the curved rod 31 (first guide rope component), and then passes through the gap (view omitted) between the front end of the curved rod 31 (first guide rope component) and the front side of the base frame 01, and then enters the guide rope hole 32 (second guide rope component). In this way, the binding rope end led out from the guide rope hole 32 (second guide rope component) is perpendicular to the plane of the trajectory of the main arm 02 rotating around the first pin shaft 11 (first fulcrum).

[0035] The rope holding part 4 located at the front of the main arm 02 comprises: a base 40; a first rope clamping part 41 and a second rope clamping part 42 arranged on the base 40 and capable of rotating around the second fulcrum 12 and engaging with each other by a spring (omitted in the figure); Figure 1 , 2 In the initial state (open state) shown in FIG. 1 , the first rope clamping member 41 can only rotate around the second fulcrum 12 in the counterclockwise direction, that is, in the direction away from the second rope clamping member 42; Figure 5 As shown, a substantially trapezoidal collision block 421 corresponding to the rope guide hole 32 (second rope guide component) is also provided at the front end of the second rope clamping component 42, and when the strapping machine is in the initial state (open state), the upper and lower planes of the collision block 421 are parallel to the base frame 01, and a berth 422 matching the rope guide hole 32 (second rope guide component) is also provided at the rear of the collision block 421.

[0036] A cutter 43 (rope cutting member) with an inclined cutting edge is provided below the base 40 .

[0037] Combination Figure 1 and Figure 6As shown, the auxiliary arm 5 (rope-binding part) has a similar arc to the main arm 02, and its lower end is hinged on the first pin shaft 11 (first fulcrum); an approximately "L"-shaped path 20 is provided on the main arm 02, and a first transmission component 21 is provided between the auxiliary arm 5 and the limiting component 012, which is composed of a pair of transmission rods 211, 212 hinged on a second pin shaft 13 that can move along the path 20, wherein the axial directions of the second pin shaft 13 and the first pin shaft 11 (first fulcrum) are parallel to each other;

[0038] A first rope-binding component 51 with a “Y”-shaped opening is provided at the front end of the auxiliary arm 5 , and a second rope-binding component 52 with a “V”-shaped opening is provided behind the first rope-binding component 51 .

[0039] The support part 6 includes a first support component 61 with a long hole (omitted in the view) in the middle of the front part of the base frame 01 and a second support component 62 with a cylindrical shape and a through hole on the right side of the first support component 61, wherein the long hole (omitted in the view) on the first support component 61 is located on the movement trajectory of the cutter 43 (rope cutting component), and the axis of the second support component 62 is located on the movement trajectory of the second rope binding component 52; Figure 3 As shown, an opening is provided at the upper part of the second support member 62, and corresponding feed ports 621 and discharge ports 622 are provided on the left and right sides; the hoop kit 7 (with a cutting component) is sleeved on the second support member 62, and can rotate with the second support member 62 as an axis, as shown in FIG. Figure 4 As shown, the hoop sleeve 4 has an approximately "V"-shaped chopping mouth 71 corresponding to the discharge port 622, and a second transmission component 22 is provided between the hoop sleeve 7 and the main arm 02. Both ends of the second transmission component 22 are hinged to the hoop sleeve 7 and the main arm 02, so that when the main arm 02 rotates around the first pin shaft 11 (first fulcrum), the hoop sleeve 7 can be driven by the second transmission component 22 to rotate around the second support component 62 as the axis.

[0040] The transmission part 8 is located behind the second supporting member 62, and includes: a one-way stop member 81 located under the handle 011, which can rotate around the third pin shaft 14, and a torsion spring (omitted in the view) is used to apply force between the one-way stop member 81 and the handle 011, so that the front part of the one-way stop member 81 is engaged with the lower wall of the handle 011 and has a tendency to rotate in the clockwise direction; a transmission guide rail 82 located between the one-way stop member 81 and the second supporting member 62 is a straight rectangular steel bar, and its width is greater than the width of the hoop material; the rear end of the transmission guide rail 82 corresponds to the front end of the one-way stop member 81 and is fixed to the handle 011, and its front part is supported by a cross partition (omitted in the view) on the base frame 01 (not fixed) In a manner), its front end extends from the feed port 621 into the second support member 62 and reaches the left side of the axis of the second support member 62, and a gap is left between the front end of the conveying guide rail 82 and the feed port 621 and is sufficient to allow the hoop material to pass through; and a first force-applying member 83 and a second force-applying member 84, wherein the first force-applying member 83 is arranged on the left side of the lower end of the main arm 02 and above the conveying guide rail 82, and the second force-applying member 84 is located on the handle 021 below the conveying guide rail 82, and when the strapping machine is in the initial state (open state), the top of the second force-applying member 84 just contacts with the bottom of the conveying guide rail 82, and the conveying guide rail 82 is in a naturally straight state.

[0041] When the strapping machine is used, the end of the strapping rope placed in the first receiving part 91 is led out, through the holes (omitted in the view) preset in the handle 011 and the lower part of the base frame 01 and the side of the front part of the base frame 01, to the front part of the bent rod 31 (the first rope guide part), and then through the gap (omitted in the view) between the front part of the bent rod 31 (the first rope guide part) and the side of the front part of the base frame 01, and then enters the rope guide hole 32 (the second rope guide part) whose direction is perpendicular to the plane of the motion trajectory of the main arm 02 rotating around the first fulcrum 11. In this way, the rope guide The direction of the tying rope end led out of the hole 32 (the second guide rope component) is perpendicular to the plane of the rotation trajectory of the main arm 02 around the first pin shaft 11 (the first fulcrum); the aluminum strip (hooping material) placed on the second receiving component 92 is led out, and the rear end of the one-way stop component 81 is pressed to make its front end detach from the lower wall of the handle 011 to allow the aluminum strip to pass through, and then the aluminum strip is introduced into the feed port 621 along the upper surface of the conveying guide rail 82 and extends out from the discharge port 622 and the shearing port 71 corresponding to the discharge port 622 to a length of about 1.5 mm.

[0042] In this way, the strapping machine enters the ready state before use.

[0043] The pair of handles 011 and 021 are squeezed to rotate the main arm 02 counterclockwise around the first pin shaft 11 (first fulcrum), so that the collision block 421 and the guide rope hole 32 are brought closer to each other until the lower plane of the collision block 421 contacts the guide rope hole 32 .

[0044] For the convenience of description and understanding below, the operation process of squeezing the pair of handles 011 and 021 from the initial state (open state) until the lower plane of the collision block 421 and the rope guide hole 32 start to contact is defined as the first stage of operation. After completing the first stage of operation, continue to squeeze the pair of handles 011 and 021. Due to the interaction between the collision block 421 and the rope guide hole 32, the second rope clamping component 42 rotates clockwise around the second fulcrum 12, and the first rope clamping component 41 and the second rope clamping component 42 that were originally engaged with each other are opened; in this way, the end of the tying rope led out of the rope guide hole 32 enters between the first rope clamping component 41 and the second rope clamping component 42; continue to squeeze the pair of handles 011 and 021, and the collision block 421 and the rope guide hole 32 continue to move relative to each other until a The handles 011 and 021 are brought close to each other and no longer rotated, and the strapping machine enters a fully closed state. The rope guide hole 32 falls into the berth 422 located at the rear of the impact block 421, and the interaction between the rope guide hole 32 and the impact block 421 disappears. Due to the action of the torsion spring (omitted in the view) between the first rope clamping component 41 and the second rope clamping component 42, the first rope clamping component 41 and the second rope clamping component 42 return to a mutually engaged state, and the end of the tying rope that has entered between the first rope clamping component 41 and the second rope clamping component 42 is clamped (held).

[0045] For the convenience of description and understanding below, the operation process of squeezing a pair of handles 011 and 021 from the completion of the first stage operation to the entering of the strapping machine into a fully closed state is defined as the second stage operation.

[0046] After completing the second stage of operation, the pair of handles 011 and 021 are loosened. Due to the force of the spring (omitted in the view) between the base frame 01 and the main arm 02, the main arm 02 rotates clockwise around the first pin shaft 11 (first fulcrum) relative to the base frame 01 until the strapping machine returns to the initial state (open state).

[0047] For the convenience of description and understanding below, the operation process of loosening the pair of handles 011 and 021 from the completion of the second stage operation until the strapping machine returns to the initial state (open state) is defined as the third stage operation.

[0048] During the third stage of operation, the rope guide hole 32 moves from the position at the berth 422 to the impact block 421. It is worth noting that during this process, the rope guide hole 32 contacts the upper plane of the impact block 421 and applies force to it. Under the action of the rope guide hole 32, the first rope clamping component 41 and the second rope clamping component 42 rotate around the second fulcrum 12 in the counterclockwise direction by a certain angle, so that the rope guide hole 32 passes through the upper plane of the impact block 421 and separates from the impact block 421. At the same time, the first rope clamping component 41 and the second rope clamping component 42 pull out a section of the tying rope clamped (held) during the second stage of operation from the rope guide hole 32. Therefore, after completing the third stage of operation, a straightened tying rope segment is formed between the rope clamping part 4 and the rope guide hole 32, and the tying machine returns to the initial state (open state).

[0049] After the third stage operation is completed, the bundled objects can be guided from the outside of the opening between the main arm 02 and the base frame 01 to the straightened tying rope segment formed after the third stage operation is completed, so that the bundled objects can press against the tying rope segment and enter the arc of the main arm 02.

[0050] After completing the first stage operation, the second stage operation and the third stage operation in sequence, the first stage operation is started for the second time. In the process of squeezing the pair of handles 011 and 021, the main arm 02 starts to rotate counterclockwise around the first pin shaft 11 (first fulcrum), and the auxiliary arm 5 (rope tying part) located on the left side rotates around the first pin shaft 11 (first fulcrum) at an angle greater than the rotation angle of the main arm 02 under the action of the first transmission component 21. In this way, the first rope tying component 51 with a "Y"-shaped opening at the head end of the auxiliary arm 5 (rope tying part) will first contact the tying rope segment located above the tied object and press it down, and then contact the tying rope segment located below the tied object to constrain the two ends (joint parts) of the tying rope segment together, and continue to press down until the first rope tying component 51 enters the first support The first supporting member 61 and the second supporting member 62 are positioned between the two ends (butt joints) of the tying rope segment, so that the two ends (butt joints) of the tying rope segment are respectively pressed onto the first supporting member 61 and the second supporting member 62 in a taut state. At the same time, the second tying rope member 52 located at the rear of the first tying rope member 51 moves to above the axis of the second supporting member 62 and presses the two ends (butt joints) of the tying rope segment close to the side of the bundled object onto the aluminum strip at the front end of the conveying guide rail 82, and also indirectly presses the aluminum strip at the front end of the conveying guide rail 82 onto the second supporting member 62, and the auxiliary arm 5 (tying rope portion) stops rotating. It should be noted that, in fact, after completing any operation of the first stage, the second tying rope member 52 can press the aluminum strip at the front end of the conveying guide rail 82 onto the second supporting member 62.

[0051] Continue to squeeze the pair of handles 011 and 021 until the lower plane of the collision block 421 contacts the guide rope hole 32 again, and the first stage of the operation is completed.

[0052] The second stage of operation is performed for the second time, that is, after completing the first stage of operation for the second time, continue to squeeze the pair of handles 011 and 021, and the hoop kit 7 (hoop part) rotates clockwise around the second support member 62 under the drive of the second transmission member 22, and the "V"-shaped chopping mouth 71 (with a cutting part) provided on the hoop kit 7 interacts with the discharge port 621 to gradually cut the aluminum strip extending out of the discharge port 622 from both sides to the middle along a direction perpendicular to the aluminum strip, and the cut portion of the aluminum strip is bent and squeezed upward under the action of the chopping mouth 71 (with a cutting part) until the aluminum strip is completely cut off, thereby the two ends (joint parts) of the binding rope segment pressed onto the second support member 62 are hooped together; continue to squeeze the pair of handles 011 and 021, and set The cutter 43 (rope cutting component) under the base 40 moves downward toward the hole position (omitted in the view) on the first supporting component 61 along with the main arm 02, so that the two end portions (joint portions) of the tying rope segment pressed onto the first supporting component 61 by the first rope binding component 51 are cut off by the cutter 43; at the same time, due to the interaction between the collision block 421 and the rope guide hole 32, the second rope clamping component 42 rotates a certain angle in the clockwise direction around the second fulcrum 12, that is, the second rope clamping component 42 and the first rope clamping component 41 change from a bite state to an open state, and the previously clamped and tightened tying rope end retracts due to its own elastic force, thereby disengaging from between the first rope clamping component 41 and the second rope clamping component 42, and the pair of handles 011 and 021 continue to be gripped and pressed until the second stage of the operation is completed.

[0053] Then, the third stage operation is performed for the second time, that is, the pair of handles 011 and 021 are released to return the strapping machine to the initial state (open state).

[0054] In fact, after the second stage operation is completed for the second time, the bundled objects have been tied, and after the third stage operation is completed for the second time, the strapping machine completely enters the initial state (open state) before the first stage operation is performed for the first time.

[0055] It should be supplemented that the first force-applying component 83 provided on the main arm 02 and the second force-applying component 84 provided on the handle 021 will respectively rotate with the main arm 02 and the handle 021 around the first pin 11 (first fulcrum); after completing any first-stage operation, the second rope-binding component 52 presses the aluminum strip located at the front end of the conveying guide rail 82 onto the second support component 62, and at the same time, the first force-applying component 83 rotates with the main arm 02 to the upper surface of the conveying guide rail 82; as the second-stage operation proceeds, the first force-applying component 83 continues to rotate counterclockwise around the first pin 11 (first fulcrum) with the main arm 02, so that the first force-applying component 83 begins to The conveying guide rail 82 applies force from top to bottom, so that the conveying guide rail 82 and the aluminum strip thereon change from a straight shape to a curved shape; since the front end (left end) of the aluminum strip is pressed on the second support component 62 by the second rope component 52 and cannot move, the other end of the aluminum strip is engaged by the one-way stop component 81, that is, the aluminum strip cannot move to the right through the one-way stop component 81. Therefore, the increased length of this section of aluminum strip between the second support component 62 and the one-way stop component 81 in the process of changing from a straight shape to a curved shape comes from the right side of the one-way stop component 81, that is, after completing any second-stage operation, the aluminum strip on the right side of the one-way stop component 81 moves a short distance to the left along the conveying guide rail 82.

[0056] After any second stage operation is completed, the third stage operation is entered, and the first force-applying component 83 and the second force-applying component 84 move in the clockwise direction around the first pin shaft 11 (first fulcrum), and the second rope-binding component 52 also moves away from the second supporting component 62 as the auxiliary arm 5 (rope-binding part) rotates, that is, the restraining force of the second rope-binding component 52 on the front end (left end) of the aluminum strip disappears, and the top-down force of the first force-applying component 83 on the conveying guide rail 82 also disappears. On the contrary, the second force-applying component 83 begins to apply force from bottom to top to the conveying guide rail 82 that has become an arc shape and the aluminum strip thereon to restore it from the arc shape to a straight state. Since the front end (left side) of the aluminum strip is no longer constrained, the right side of the aluminum strip is controlled by the one-way stop component 81. Therefore, when the aluminum strip returns to a straight state from the arc shape, its front end (left side) extends a small section toward the discharge port 622, that is, the aluminum strip consumed after each bundling is completed will be automatically replenished.

[0057] The purpose of the above description is to disclose the technical solution and principle of the present invention in as much detail as possible. In fact, after the tying rope and the aluminum strap are installed, the tying can be completed by only performing a "grip-release-grip-release" operation of a pair of handles 011 and 021. The aluminum strap consumed due to tying is automatically replenished after each tying is completed, so that the tying machine enters a ready state before the next tying. The operation is simple and the degree of automation is high.

[0058] The above-described embodiment only expresses one implementation of the present invention, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
