Abstract
Description
Technical Field
[0001] This application relates to the field of spiral wound tube cutting technology, and more specifically, to a spiral wound tube cutting control method and apparatus. Background Technology
[0002] Spiral wound tubes are typically formed by spirally winding material strips, with adjacent strips interlocking to allow for axial expansion and contraction. To meet production needs, the spiral wound tubes usually need to be cut to a predetermined length.
[0003] During the cutting process, if the wound tube is not fully tightened, there is still room for movement between adjacent strips, and the axial length of the wound tube is easily affected by the stress state. Especially for longer wound tubes, when subjected to axial pushing or compression, unstable areas may arch, which in turn affects the stability of the cutting position and results in poor consistency of the length of the wound tube after cutting. Summary of the Invention
[0004] To address the issue of inconsistent lengths in the finished spiral wound tubes, this application provides a method and apparatus for controlling the cutting of spiral wound tubes.
[0005] In a first aspect, this application provides a method for controlling the cutting of a wound tube, the method comprising:
[0006] Based on the fact that the winding tube unit is placed on the upper side of the support unit, and there is a gap between the winding tube unit and the limiting unit, the control pushing unit pushes the winding tube unit to move toward the limiting unit; wherein, the winding tube unit includes at least one winding tube body; the winding tube body is formed by spirally winding a material strip with an S-shaped cross section, and two adjacent turns of the material strip are interlocked with each other; when the winding tube unit is placed on the upper side of the support unit, the axis of the winding tube unit is set horizontally;
[0007] During the process of the pushing unit moving toward the limiting unit, when the winding tube unit abuts against the limiting unit, the pressing unit is controlled to abut against the upper side of the winding tube unit and move a preset distance toward the limiting unit; wherein, the winding tube unit is gradually compressed during the extrusion process between the pushing unit and the limiting unit, and the tightening area of the winding tube unit gradually expands along the feeding direction until it is in a pressed state.
[0008] Based on the fact that the winding tube unit is in the compressed state, the pushing unit and the pressing unit are controlled to stop moving, and the cutting unit is controlled to cut the winding tube unit.
[0009] Optionally, the winding tube cutting control method further includes:
[0010] Once the cutting is complete, the winding tube unit between the cutting unit and the limiting unit is unloaded;
[0011] Once the material is fed, return to the above-ground position of the winding tube unit on the upper side of the carrying unit, with a gap between the winding tube unit and the limiting unit, and control the pushing unit to push the winding tube unit toward the limiting unit.
[0012] Optionally, the winding tube unit is placed on top of the carrying unit, and there is a gap between the winding tube unit and the limiting unit. Controlling the pushing unit to push the winding tube unit toward the limiting unit includes:
[0013] Based on the fact that the winding tube unit is placed on the upper side of the carrying unit and there is a gap between the winding tube unit and the limiting unit, the pushing unit is controlled to push the winding tube unit toward the limiting unit at a first speed until the winding tube touches the limiting unit.
[0014] During the process of the pushing unit moving toward the limiting unit, when the winding tube unit abuts the limiting unit, the pushing unit is controlled to push the winding tube unit toward the limiting unit at a second speed until the winding tube unit is in the pressed state.
[0015] Wherein, the first speed is greater than the second speed.
[0016] Optionally, the preset distance is the spacing between the cutting unit and the limiting unit.
[0017] Optionally, the preset distance is greater than the distance between the cutting unit and the limiting unit.
[0018] Optionally, the winding tube cutting control method further includes:
[0019] Once the cutting is complete, the clamping unit is controlled to move a preset distance away from the limiting unit to reset the clamping unit.
[0020] Optionally, the preset distance is positively correlated with the total length of the remaining winding tube units on the bearing unit.
[0021] Secondly, this application provides a winding tube cutting control device, which is applied to the winding tube cutting control method described in any one of the first aspects;
[0022] The winding tube cutting control device includes:
[0023] A support unit extends horizontally and is used to support the wound tube unit;
[0024] A pushing unit is slidably arranged horizontally; the sliding direction of the pushing unit is parallel to the extension direction of the bearing unit; the pushing unit is used to push the winding tube unit on the upper side of the bearing unit.
[0025] The clamping unit is horizontally slidable; the sliding direction of the clamping unit is parallel to the sliding direction of the pushing unit; when the winding tube unit is placed on the upper side of the bearing unit, the clamping unit abuts against the upper side of the winding tube unit.
[0026] A cutting unit, located above the support unit, is used to cut the winding tube unit on the support unit;
[0027] A limiting unit is located on the upper side of the bearing unit to position the winding tube unit;
[0028] The feeding unit, the pressing unit, the cutting unit, and the limiting unit are arranged sequentially along the extension direction of the bearing unit.
[0029] Optionally, the clamping unit includes a pressure roller and a clamping drive unit; the pressure roller is rotatably disposed around its own axis and the clamping drive unit; the clamping drive unit drives the pressure roller to move in the horizontal direction;
[0030] As the pressure roller presses the upper side of the winding tube unit and moves toward the limiting unit, the winding tube unit bears the frictional force applied by the pressure roller in the direction of the pushing unit.
[0031] Optionally, the bearing unit includes two bearing rollers; the two bearing rollers are arranged in parallel.
[0032] With the winding tube unit placed on top of the carrying unit, the winding tube unit overlaps the upper area between the two carrying rollers.
[0033] To address the issue of inconsistent lengths in the finished spiral wound tubes, this application offers the following advantages:
[0034] This application uses a support unit to support the winding tube unit, ensuring the stability of the winding tube unit's posture throughout the entire process of pushing, clamping, and cutting. It relies on a pushing unit to push the tube and a limiting unit to position the end, using the relative position of the limiting unit and the cutting unit to precisely limit the length of the winding tube to be cut, achieving fixed-length cutting. Crucially, after the winding tube unit abuts against the limiting unit, the pushing unit does not stop but continues to apply force, while the clamping unit presses down synchronously with the pushing unit's movement and moves towards the limiting unit. At this point, the tightening does not begin from the limiting unit end, but rather forms from the rear end where the pushing unit is located, and gradually expands forward along the feeding direction; the clamping unit moves forward, always pressing down on the loose area at the tightening front that has not yet engaged, preventing it from arching, and follows synchronously as the tightening area expands. Through this coordinated action of the pushing unit and the clamping unit, the winding tube tightens segment by segment from back to front along the axial direction, effectively eliminating axial expansion and contraction allowance and improving the length consistency of each segment of the cut tube.

[0043] The winding tube unit 10 includes one or more winding tube bodies. The winding tube body is formed by spirally winding a strip with an S-shaped cross-section. Adjacent turns of the strip interlock, allowing the winding tube body to expand and contract along its axial direction. When the winding tube body is in an uncompressed state, there is a relative allowance between the turns of the strip, and the axial length of the winding tube body may change with the stress state; if it is cut directly in this state, it is easy to cause differences in the actual length of different cut pieces.
[0044] Example 1:
[0045] In this embodiment, a method for controlling the cutting of wound tubes is provided, such as... Figure 1 As shown, the winding tube cutting control method includes steps S10 to S30.
[0046] In step S10, the winding tube unit 10 is placed on top of the support unit 20, with the axis of the winding tube unit 10 extending horizontally and a gap maintained between the winding tube unit 10 and the limiting unit 60. The support unit 20 provides support for the winding tube unit 10, ensuring a stable bearing posture during pushing, pressing, and cutting. The pushing unit 30 is controlled to move along the extension direction of the support unit 20 to push the winding tube unit 10 toward the limiting unit 60. The limiting unit 60 is used to position the end of the winding tube unit 10 to be cut. When the winding tube unit 10 abuts against the limiting unit 60, the length to be cut of the winding tube unit 10 is determined by the relative position between the limiting unit 60 and the cutting unit 50.
[0047] In step S20, as the pushing unit 30 moves toward the limiting unit 60, when the winding tube unit 10 contacts the limiting unit 60, the pressing unit 40 is controlled to contact the upper side of the winding tube unit 10 and move a preset distance toward the limiting unit 60. At this time, the pushing unit 30 does not stop, but continues to apply a pushing force toward the limiting unit 60; the movement of the pressing unit 40 is synchronized with the continuous advancement of the pushing unit 30, that is, the pressing unit 40 follows the movement of the pushing unit 30 and gradually moves toward the limiting unit 60. It should be understood that at the initial moment when the winding tube unit 10 just contacts the limiting unit 60, each coil of material is still in a loose state and has not yet been tightly fastened. As the pushing unit 30 continues to push, due to the obstruction of the limiting unit 60 at the front end, the tightening (i.e., the interlocking of adjacent material coils) first forms from the rear end of the side where the pushing unit 30 is located, and this tightening area gradually expands forward along the feeding direction (i.e., toward the limiting unit 60). During this process, the material strip in front of the tightening area remains loose and is prone to arching under pressure. The gradual movement of the clamping unit 40 toward the limiting unit 60 ensures that its clamping action is always applied to this loose area that has not yet tightened. That is, as the tightening area expands forward, the clamping unit 40 moves forward synchronously, limiting the loose area segment by segment on the bearing unit 20 to prevent it from arching under pressure. Through the continuous pushing of the pushing unit 30 and the synchronous movement of the clamping unit 40, the tightening area of the winding tube unit 10 gradually expands along the feeding direction until the winding tube unit 10 is in a clamped state.
[0048] In step S30, after the winding tube unit 10 is in a compressed state, the pushing unit 30 and the pressing unit 40 are controlled to stop moving, and the cutting unit 50 is controlled to cut the winding tube unit 10. Since the adjacent strips of the winding tube body have been interlocked before cutting, the axial expansion and contraction allowance of the winding tube unit 10 is eliminated or reduced, thereby improving the consistency of the length of each cut piece.
[0049] In this embodiment, the bearing unit 20 supports the winding tube unit 10, ensuring the stability of the winding tube unit 10 throughout the entire process of pushing, pressing, and cutting. The pushing unit 30 pushes the winding tube, and the limiting unit 60 positions the end. The relative position of the limiting unit 60 and the cutting unit 50 precisely limits the length of the winding tube unit 10 to be cut, achieving fixed-length cutting. Crucially, after the winding tube abuts against the limiting unit 60, the pushing unit 30 does not stop but continues to apply force, while the pressing unit 40 presses down synchronously with the pushing unit 30 and moves towards the limiting unit 60. At this time, the tightening does not start from the limiting unit end, but forms from the rear end where the pushing unit is located, and gradually expands forward along the feeding direction. The forward movement of the pressing unit 40 is precisely to always press down the loose area that has not yet been engaged at the tightening front edge, preventing it from arching, and it moves synchronously as the tightening area expands. Through the coordinated action of the pushing unit 30 and the pressing unit 40, the winding tube is tightened segment by segment from back to front along the axial direction, and the axial expansion and contraction allowance is fully eliminated, effectively improving the length consistency of each segment of the cut tube.
[0050] Furthermore, step S10 includes steps S11 and S12. The pushing unit 30 has two pushing stages: a first speed and a second speed.
[0051] Step S11: When there is still a gap between the winding tube unit 10 and the limiting unit 60, control the pushing unit 30 to push the winding tube unit 10 to move at a first speed.
[0052] Step S12: When the winding tube unit 10 contacts the limiting unit 60, the pushing unit 30 is controlled to switch to a second speed less than the first speed to continue pushing the winding tube unit 10.
[0053] This embodiment improves feeding efficiency by using a faster first speed in the approach phase to the limiting unit 60; and by using a slower second speed in the clamping phase, the winding tube unit 10 can be gradually tightened, reducing the risk of the winding tube unit 10 arching when subjected to axial pressure.
[0054] Furthermore, the preset distance can be set as the gap between the cutting unit 50 and the limiting unit 60. In this case, the pressing unit 40 moves a preset distance toward the limiting unit 60 to fully press the winding tube unit 10 corresponding to the length to be cut before cutting.
[0055] Furthermore, the preset distance can be greater than the distance between the cutting unit 50 and the limiting unit 60, so that the pressing unit 40 continues to apply a stabilizing effect to the winding tube unit 10 outside the cutting area, further ensuring the pressing state of the winding tube unit 10 to be cut during the cutting process.
[0056] When the preset distance is greater than the distance between the cutting unit 50 and the limiting unit 60, after the cutting is completed, the pressing unit 40 needs to be controlled to move a preset distance away from the limiting unit 60 so that the pressing unit 40 can be reset and reserve movement space for the next pressing operation.
[0057] Furthermore, the preset distance can be positively correlated with the total length of the remaining winding tube units 10 on the bearing unit 20. For winding tube units 10 with a larger remaining length, using a larger preset distance can allow the pressing area to gradually expand in the feeding direction, thereby improving the stable support effect on the longer winding tube units 10; for winding tube units 10 with a smaller remaining length, the preset distance can be reduced accordingly to shorten the reciprocating stroke of the pressing unit 40.
[0058] Furthermore, the winding tube cutting control method also includes steps S40 and S50.
[0059] Step S40: After the cutting is completed, the winding tube unit 10 located between the cutting unit 50 and the limiting unit 60 is unloaded.
[0060] In step S50, after the material is unloaded, the control pusher unit 30 pushes the remaining winding tube unit 10 on the bearing unit 20 to move toward the limiting unit 60 again, and repeats the feeding, pressing, cutting and unloading process until the cutting operation of the winding tube unit 10 is completed.
[0061] Furthermore, the winding tube cutting control method also includes step S60.
[0062] In step S60, when the cutting is completed, the clamping unit 40 is controlled to move a preset distance away from the limiting unit 60 to reset the clamping unit 40.
[0063] Example 2:
[0064] In this embodiment, as Figure 2 , Figure 3 , Figure 4 As shown, the winding tube cutting control device includes a carrying unit 20, a pushing unit 30, a pressing unit 40, a cutting unit 50, and a limiting unit 60. The carrying unit 20 extends horizontally; the pushing unit 30 is slidably arranged horizontally, and the sliding direction of the pushing unit 30 is parallel to the extending direction of the carrying unit 20; the pressing unit 40 is slidably arranged horizontally, and the sliding direction of the pressing unit 40 is parallel to the sliding direction of the pushing unit 30. The cutting unit 50 and the limiting unit 60 are located above the carrying unit 20, and the pushing unit 30, pressing unit 40, cutting unit 50, and limiting unit 60 are arranged sequentially along the extending direction of the carrying unit 20.
[0065] The pushing unit 30 applies a pushing action along the feeding direction from one side of the winding tube unit 10, causing the winding tube unit 10 to move towards the limiting unit 60. The limiting unit 60 is used to block and position the end of the winding tube unit 10. The clamping unit 40 is disposed between the pushing unit 30 and the cutting unit 50, abutting against the upper side of the winding tube unit 10 during the clamping stroke, and moving towards the limiting unit 60 as the clamping area expands. The cutting unit 50 is located between the clamping unit 40 and the limiting unit 60, and is used to complete the cutting when the winding tube unit 10 is in the clamped state.
[0066] Furthermore, such as Figure 5 As shown, the clamping unit 40 includes a pressure roller 41 and a clamping drive unit 42. The pressure roller 41 is rotatably connected to the clamping drive unit 42 around its own axis, and the clamping drive unit 42 is used to drive the pressure roller 41 to move in the horizontal direction. When the pressure roller 41 clamps the upper side of the winding tube unit 10 and moves toward the limiting unit 60, the winding tube unit 10 bears the frictional force applied by the pressure roller 41 in the direction of the pushing unit 30. Since the pressure roller 41 can rotate relative to the clamping drive unit 42, the interaction between the pressure roller 41 and the winding tube unit 10 is mainly rolling contact; during the process of the pressure roller 41 moving along the limiting unit 60, the pressure roller 41 further compacts the already tightened area, making the area more compact and stable, realizing the steady expansion of the tightened area from the pushing unit to the limiting unit, thereby providing support for the steady tightening of the subsequent un-tightened area.
[0067] It is worth noting that, such as Figure 4 and Figure 5 As shown, the axis of the pressure roller 41 is set perpendicular to the axis of the winding tube unit 10.
[0068] Furthermore, the support unit 20 includes two support rollers arranged in parallel. When the winding tube unit 10 is placed on top of the support unit 20, the winding tube unit 10 overlaps the upper area between the two support rollers. The two support rollers together support the winding tube unit 10, keeping its axis horizontal during pushing and pressing. Optionally, the support rollers can rotate around their own axes; during the cutting process, the rotation of the support rollers can drive the winding tube unit 10 to rotate, cooperating with the cutting unit 50 to complete the circumferential cutting of the winding tube unit 10.
[0069] In other embodiments, the winding tube cutting control device may further include a control unit connected to the feeding unit 30, the clamping unit 40, and the cutting unit 50. Based on the contact state between the winding tube unit 10 and the limiting unit 60, the control unit controls the feeding unit 30 to switch speeds during the feeding and clamping stages, and controls the clamping unit 40 to perform clamping or resetting actions. After determining that the winding tube unit 10 has reached the clamping state, the control unit controls the cutting unit 50 to perform the cutting action. Thus, it is possible to adapt to winding tube units 10 with different remaining lengths without frequently adjusting the initial position of the clamping unit 40, and to achieve continuous cutting operations.
[0070] The carrying unit 20 also includes a driving unit, which is electrically connected to the carrying roller. The driving unit is used to drive the carrying roller to rotate so as to move the winding tube unit 10 toward the limiting unit 60.
[0071] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
