Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and particularly to a winding and packaging device capable of performing two-end bandaging. Background Art

[0002] For the batch packaging of long lead screws with a specified length of about two meters and a diameter of about 1 - 2 centimeters, before packaging, a preset number of long lead screw ends need to be aligned, and then manually packaged or packaged by a packaging machine.

[0003] When manually packaging, workers need to manually wind the winding tape around the long lead screw in circles first, and then wind the braided tape around the long lead screw in circles, so that the winding tape wraps the long lead screw, the braided tape wraps the winding tape, and finally fix the two ends of the braided tape with tape to achieve the packaging of the long lead screw. However, manual packaging requires a large amount of time and labor costs, and it is difficult to ensure the consistency of manual packaging quality. Different workers have different degrees of proficiency and techniques, resulting in uneven tightness and uniformity of bandaging, and extremely low efficiency.

[0004] When using a packaging machine for packaging, generally, the winding tape and the braided tape rotate around the long lead screw simultaneously while the long lead screw moves axially, so that the winding tape and the braided tape automatically wind and wrap the long lead screw. However, the existing packaging machine cannot automatically bandage the two ends of the long lead screw. After the winding tape and the braided tape are wound and packaged, it is still necessary to manually cut the winding tape and the braided tape at both ends of the long lead screw, and then manually bandage the two ends with tape. Manual bandaging at both ends will result in problems such as inconsistent bandaging quality, high labor intensity, slow bandaging speed, and low production efficiency, and it is difficult to meet the requirements of large-scale industrial production for efficient and rapid packaging.

Detailed implementation manners

[0018] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0019] Please refer to Figures 1 to 9 Figures 1 to 9 , an embodiment of the present application provides a winding and packing device capable of wrapping both ends, including a frame 1, a cutting and gathering mechanism 2, and two end wrapping mechanisms 3 located on both sides of the cutting and gathering mechanism 2; there is a first spacing 41 between two adjacent materials 4.

[0020] Please refer to Figure 3 and Figures 6 to 9 Figure 3 , the cutting and gathering mechanism 2 includes a driving mechanism, a cutting device 23, and a gathering plate 25. The driving mechanism includes a first linear driving device 21, a transverse moving seat 22, and a second linear driving device 24. The first linear driving device 21 is fixedly installed on the frame 1, the transverse moving seat 22 is fixedly installed at the output end of the first linear driving device 21, and the cutting device 23 and the second linear driving device 24 are fixedly installed on the transverse moving seat 22; the cutting device 23 can move along the radial direction of the material under the drive of the first linear driving device 21 to cut the packing tape in the middle of the first spacing 41. The part of the packing tape extending out of the end of the material 4 after cutting forms a wrapping part 42, and the part of the packing tape wrapping the material 4 after cutting forms a wrapping portion; the gathering plate 25 can move along the radial direction of the material under the drive of the first linear driving device 21 to push the wrapping part 42 to move and cover the end of the material 4, and then can move along the axial direction of the material under the drive of the second linear driving device 24, so that the wrapping part 42 and the wrapping portion have an overlapping part within the wrapping range of the end wrapping mechanism 3. The overlapping part is specifically that the wrapping part 42 overlaps with the projection of the wrapping portion in a certain radial direction of the material. In this way, when the end wrapping mechanism 3 winds the overlapping part with an annular adhesive tape, the wrapping part 42 can be pressed and fixed on the wrapping portion.

[0021] The material is a lead screw bundle that is approximately cylindrical after winding and packing, and the axial and longitudinal directions are both the axial and longitudinal directions of the lead screw bundle. The wrapping part 42 is the part of the packing tape extending outside the end of the material after cutting, and the wrapping portion is the part of the packing tape surrounding the material body after cutting.

[0022] The first linear driving device 21 is selected from an electric slide table, a pneumatic slide table, a linear motor and other components capable of realizing linear motion, which can drive the transverse moving seat 22 to move to an accurate position. The first linear driving device 21 drives the transverse moving seat 22 to move in a direction perpendicular to the conveying direction of the material 4, which is convenient for driving the cutting device 23 to cut the packing tape.

[0023] The cutting device 23 is selected from a metal cutting knife 305 with a blade, or a cutting saw that can automatically move up and down for cutting, or a cutting saw that can automatically rotate for cutting, or a hot melt cutting knife 305 that can heat and cut the packing tape by hot melting.

[0024] The second linear drive device 24 corresponds to the gathering plate 25 one by one. The second linear drive device 24 uses an electric slide or a pneumatic slide, a linear motor or other components capable of achieving linear motion, and can drive the gathering plate 25 to move to a precise position.

[0025] When the first linear drive device 21 drives the cutting device 23 to cut the packaging tape, the gathering plate 25 pushes the wrapping portion 42 to move at a position close to the end of the material 4, so that the wrapping portion 42 can maximize the coverage of the end of the material 4. The length of the wrapping portion 42 is greater than the maximum width of the end of the material 4, so part of the wrapping portion 42 will extend out of the end of the material 4, and this part is recorded as the extension portion 421; after the wrapping portion 42 covers the end of the material 4, the second linear drive device 24 drives the gathering plate 25 to move, so that the gathering plate 25 pushes the extension portion 421 to move toward the side close to the material 4, so that the extension portion 421 will overlap with the wrapping portion in the axial direction of the material 4, and the overlapping portion is in the wrapping range of the end wrapping mechanism 3, and the end wrapping mechanism 3 wraps the tape 312 around the overlapping portion, thereby wrapping and fixing the end of the material 4.

[0026] See also Figure 1 and Figure 2 The end wrapping mechanism 3 is symmetrically arranged on both sides of the cutting and gathering mechanism 2, see Figure 3 as well as Figures 5 to 7 The end wrapping mechanism 3 includes a second base plate 301, a second rotating ring body 302, a second winding rotation driving device 303, a cutting frame 304, a cutting knife 305, an intercepting plate 306, a clamping plate 307, a first driving device 308, a second driving device 309, a third driving device 310, a second guide wheel 317, a second driving wheel 318, a second driving gear 319, and a second driven gear 320.

[0027] The second substrate 301 is provided with a second circular hole 311 , the second rotating ring body 302 is rotatably mounted on the second substrate 301 , and the second winding rotation driving device 303 drives the second rotating ring body 302 to rotate around the second circular hole 311 .

[0028] The second rotating ring body 302 is fixed with a tape fixing rod 313 for installing the tape 312 and a guide rod for guiding the tape 312. The tape 312 can be detachably installed on the tape fixing rod 313, which can be specifically an interference installation. The cutting frame 304, the intercepting plate 306, and the clamping plate 307 are all hinged to the frame 1. The frame 1 is fixed with an articulated seat corresponding to the cutting frame 304, the intercepting plate 306, and the clamping plate 307. One end of the cutting frame 304, the intercepting plate 306, and the clamping plate 307 are all hingedly connected to the articulated seat through a pin shaft; the cutter 305 is fixedly installed on the cutting frame 304; the cutting frame 304, the intercepting plate 306, and the clamping plate 307 are arranged in sequence.

[0029] The intercepting plate 306 is driven to rotate by the second driving device 309 so that the tape 312 bypasses the intercepting plate 306; the clamping plate 307 is driven to rotate by the third driving device 310 so that the clamping plate 307 cooperates with the intercepting plate 306 to clamp the tape 312; the cutter holder 304 is driven to rotate by the first driving device 308 so that the cutter 305 cuts off the tape 312; one end head bandaging mechanism 3 also winds the tape 312 around the packaging tape passing through it and at the first spacing 41; a plurality of second guide wheels 317 are provided, and both the second guide wheels 317 and the second driving wheels 318 are rotatably mounted on the second substrate 301. A second annular groove 321 is provided on the outer edge of the second rotating ring body 302. The second guide wheels 317 and the second driving wheels 318 are in rolling connection with the second annular groove 321. The second driving gear 319 is fixedly mounted on the output end of the second winding and rotating driving device 303, and the second driven gear 320 is fixedly mounted on the second driving wheel 318. The second driving gear 319 meshes with the second driven gear 320.

[0030] The second winding and rotating driving device 303 selects a stepping motor or a servo motor. The second winding and rotating driving device 303 drives the second driven gear 320 and the second driving wheel 318 to rotate through the second driving gear 319. By providing the second guide wheels 317 and the second annular groove 321, the second rotating ring body 302 can be stably supported, so that the second rotating ring body 302 can be rotatably mounted on the second substrate 301. The second driving wheel 318 drives the second rotating ring body 302 to rotate, and the second guide wheels 317 rotate together with the second rotating ring body 302, so that the second rotating ring body 302 can rotate stably. The second rotating ring body 302 drives the tape fixing rod 313 to rotate, and the tape 312 on the tape fixing rod 313 can rotate around the material 4 passing through the second circular hole 311, so as to wind the tape 312 around the material 4.

[0031] In order to make the packaging tape still maintain a quasi-cylindrical shape and not loosen after being cut by the cutting device 23, it is necessary to shape the packaging tape wound with the tape 312. Therefore, when the material 4 passes through one end head bandaging mechanism 3, specifically, it can be the end head bandaging mechanism 3 close to the feeding direction of the material 4. This end head bandaging mechanism 3 winds the tape 312 around the packaging tape passing through it and at the first spacing 41. In this way, after the cutting device 23 cuts the packaging tape at the first spacing 41, the packaging tape can still maintain the original quasi-cylindrical shape, that is, a quasi-cylindrical bandaging part 42 is formed, which is convenient for bandaging and fixing the end of the material 4. The above-mentioned packaging tape is a winding tape 610 and a braided tape 611 wrapped around the lead screw.

[0032] After the tape 312 is completely wound and the second winding rotation drive device 303 is about to stop rotating, when the second drive device 309 drives the interception plate 306 to rotate upward, so that the tape 312 bypasses the interception plate 306, and the tape 312 is attached to the bottom of the interception plate 306. After the tape 312 bypasses the interception plate 306, the second winding rotation drive device 303 stops rotating; subsequently, the third drive device 310 drives the clamping plate 307 to rotate upward, the upper end of the clamping plate 307 contacts the tape 312, and the clamping plate 307 and the interception plate 306 cooperate to clamp the tape 312; subsequently, the first drive device 308 drives the cutter holder 304 to rotate upward, driving the cutter 305 to cut the tape 312; the next time the tape 312 is wound, because the clamping plate 307 and the interception plate 306 cooperate to clamp the tape 312, the second winding rotation drive device 303 can directly drive the second rotating ring body 302 to rotate, so that the tape 312 is wound on the material 4. When the tape 312 rotates to be close to the interception plate 306, the tape 312 has adhered to the material 4. At this time, the third drive device 310 drives the clamping plate 307 to rotate downward to reset, the clamping plate 307 and the interception plate 306 no longer clamp the tape 312, and the second drive device 309 drives the interception plate 306 to rotate downward to reset, so that the interception plate 306 avoids the tape 312 that is about to pass.

[0033] When the cutter holder 304, the interception plate 306, and the clamping plate 307 are in the maximum contraction state with an inclined downward direction when not working, they will not interfere with the rotating tape 312.

[0034] Please refer to Figure 3 、 Figure 5 、 Figure 6 and Figure 7 In an embodiment, to facilitate the first drive device 308 to drive the cutter holder 304 to rotate, the second drive device 309 to drive the interception plate 306 to rotate, and the third drive device 310 to drive the clamping plate 307 to rotate, the end wrapping mechanism 3 further includes a first push rod 314, a second push rod 315, and a third push rod 316.

[0048] Please refer to Figure 2 , Figure 3 , Figure 5 , in an embodiment, to facilitate controlling the first spacing 41 between two adjacent materials 4, ensure that the first spacing 41 remains constant, and facilitate the length of the wrapping portion 42 to stably wrap the end of the material 4 after cutting the packing tape at the first spacing 41, a first proximity switch 11 and a second proximity switch 12 for detecting the position of the end of the material 4 are installed on the frame 1.

[0049] The first proximity switch 11 can be an infrared proximity switch, an inductive proximity switch, a magnetic induction proximity switch, a photoelectric proximity switch, etc.; since the packing tape is wound around the material 4, and the material 4 in this embodiment is a long lead screw made of iron or steel metal material, the second proximity switch 12 and the third proximity switch 13 are set as inductive proximity switches or magnetic induction proximity switches, which can be not interfered by the plastic packing tape.

[0050] When the first proximity switch 11 detects the signal of the head end of the material 4, the first conveying mechanism 5 stops conveying the material 4. At this time, the distance between the material 4 on the first conveying mechanism 5 and the material 4 on the second conveying mechanism 7 is the first spacing 41; when the second proximity switch 12 detects the signal of the head end of the material 4, one of the end wrapping mechanisms 3 starts to work, and winds the adhesive tape 312 around the packing tape at the first spacing 41; when the third proximity switch 13 detects the signal of the head end of the material 4, the second conveying mechanism 7 stops conveying the material 4, and the cutting and gathering mechanism 2 starts to work, and then the two end wrapping mechanisms 3 work; after the two end wrapping mechanisms 3 complete the end wrapping work, the first conveying mechanism 5, the second conveying mechanism 7, the third conveying mechanism 8, and the winding and packing mechanism 6 work simultaneously and synchronously.
