[0013] Figure 1 This is a schematic diagram of the automatic roll changing device in an embodiment of the present invention. Detailed Implementation
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.
[0015] like Figure 1 As shown in the figure, the present invention proposes an automatic roll changing device for continuous production of roll materials, including a sensing and metering device 1, a feeding and cutting device 3, an adhesive tape applying device 4, a roll changing device 5, a first take-up roller 6, and a second take-up roller 7. The sensing and metering device 1 is located upstream of the inlet of the feeding and cutting device 3; the sensing and metering device 1 is used to measure the length of the conveying belt 2. The feeding and cutting device 3 is used to output the material strip 2 and to cut the material strip 2; The roll changing device 5 is located downstream of the outlet of the feeding and cutting device 3; the first take-up roller 6 and the second take-up roller 7 are installed at two opposite positions on the roll changing device 5; the first take-up roller 6 and the second take-up roller 7 are respectively used to mount a core 8; the roll changing device 5 is used to exchange the positions of the first take-up roller 6 and the second take-up roller 7, so that one of the take-up rollers 7 is close to the outlet of the feeding and cutting device 3, and the other take-up roller 7 is away from the outlet of the feeding and cutting device 3. Below the feeding and cutting device 3, there is a tape applicator 4, which is used to attach the end of the tape to the core 8 on the take-up roller near the outlet of the feeding and cutting device 3.
[0016] After the material strip 2 is conveyed by the feeding and cutting device 3, it is sent out from the outlet of the feeding and cutting device 3. The end of the material strip 2 is attached to the core 8 on the take-up roller shaft near the outlet of the feeding and cutting device 3 by the tape application device 4. Assuming that the core 8 on the first take-up roller shaft 6 is close to the outlet of the feeding and cutting device 3, the first take-up roller shaft 6 rotates, and the core 8 on the first take-up roller shaft 6 also rotates to wind up the material strip 2. An empty core 8 is placed on the second take-up roller shaft 7. At the same time, the sensing and measuring device 1 measures the length of the conveyed material strip 2. When the preset length is reached, the controller (not shown in the figure) causes the feeding and cutting device 3 to cut the material strip 2, and the core 8 on the first take-up roller shaft 6 is then fully wound. At this time, the roll changing device 5 is activated, and the positions of the first take-up roller 6 and the second take-up roller 7 are swapped. The core 8 on the second take-up roller 7 is close to the outlet of the material cutting device 3. The material feeding and cutting device 3 continues to feed the material strip 2. The end of the material strip 2 is attached to the core 8 on the second take-up roller 7 near the outlet of the material feeding and cutting device 3 by the tape application device 4. The second take-up roller 7 rotates, and the core 8 on the second take-up roller 7 winds up the material strip 2. At the same time, the fully rolled material can be removed from the first take-up roller 6.
[0017] Specifically, the sensing and measuring device 1 is a color mark sensing device; the product units on the material strip 2 are usually colored and have a fixed length, such as 10cm to 20cm, and there are blank intervals between the product units on the material strip 2. Therefore, the material strip 2 can be counted by the color mark sensing device, and the length of the material strip 2 can be obtained.
[0018] Specifically, the feeding and cutting device 3 is equipped with a servo roller mechanism and a cutting mechanism; the cutting mechanism is located downstream of the servo roller mechanism; the servo roller mechanism is a pair of synchronous rollers, and the feeding belt 2 passes between the pair (two) synchronous rollers and conveys the material belt 2; the cutting mechanism can use a cutter that moves up and down to cut the material belt 2.
[0019] Specifically, the tape application device 4 includes an application bracket 401, on which an application cylinder 402 is mounted. The cylinder rod of the application cylinder 402 faces the take-up roller shaft near the outlet of the feeding and cutting device 3. A vacuum suction head 403 is provided at the end of the cylinder rod of the application cylinder 402. The vacuum suction head 403 generates suction force by evacuating air, allowing the operator to adsorb a piece of single-sided tape onto the vacuum suction head 403 with the sticky side of the single-sided tape facing outwards. After the material tape 2 is cut, subsequent material tapes... 2. When the material strip 2 is output through the outlet of the feeding and cutting device 3, the end of the material strip 2 hangs down and is attracted by the vacuum suction head 403 at the end of the cylinder rod. The end of the material strip 2 is pasted to a part of the adhesive surface of the single-sided tape. The pasting cylinder 402 is activated, and the cylinder rod extends towards the empty core 8 on the take-up roller shaft near the outlet of the feeding and cutting device 3. The other part of the adhesive surface of the single-sided tape is then pasted onto the empty core 8, thus pasting the end of the material strip 2 onto the core 8 on the take-up roller shaft near the outlet of the feeding and cutting device 3.
[0020] Specifically, the roll changing device 5 includes a turntable 501, with a drive motor connected to the center of the back side of the turntable 501; a first take-up roller shaft 6 and a second take-up roller shaft 7 are installed at two opposite positions on the front side of the turntable 501; when the turntable 501 rotates, rotating 180° will exchange the positions of the first take-up roller shaft 6 and the second take-up roller shaft 7. Figure 1 The side of the turntable 501 facing the reader is the front, and the side away from the reader is the back. It should be noted that... Figure 1 The runway shape on the front of turntable 501 represents a protective shield.
[0021] Specifically, both the first take-up roller 6 and the second take-up roller 7 are equipped with air expansion shafts, and the first take-up roller 6 and the second take-up roller 7 are driven by a servo motor respectively; each servo motor is installed on the back of the turntable 501; when the empty core 8 is fitted onto the first take-up roller 6 or the second take-up roller 7, the core can be fixed by the air expansion shaft.
[0022] Specifically, the core 8 has round baffles 801 on both sides, which can make the material strip 2 roll neat.
[0023] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
