Description

Technical Field

[0001] This application relates to the field of sheet material feeding equipment, and in particular to a transfer-type sheet material feeder. Background Technology

[0002] Currently, in the field of automated industrial feeding, it is necessary to separate the sheet material from its backing paper. Sheet materials include, but are not limited to, labels and other materials. To facilitate transportation and prevent dust from adhering to the adhesive side of the sheet material, a backing paper is usually attached to the adhesive side, and then the backing paper is removed during the feeding process.

[0003] Traditional feeders typically use material grippers and their corresponding mechanisms to tear off the backing paper. The process usually involves the grippers holding the blank area between the backing paper and the sheet material, and then the mechanism drives the grippers to move and tear off the backing paper. This method not only requires a large blank area on the backing paper for the grippers to hold, resulting in waste, but also prevents continuous feeding during the backing paper tearing process. The feeders must wait for the grippers to tear off the backing paper and reset before feeding the next sheet, leading to a feeding interval of several seconds between two sheets, resulting in low efficiency.

[0004] Therefore, there is a need for a sheet feeder that reduces waste by minimizing blank space on the backing paper and improves efficiency by reducing feeding intervals. Utility Model Content

[0015] Furthermore, the traction mechanism includes a tape roll and a waste roll; one end of the tape is wound around the tape roll, and the other end is wound around the waste roll after passing the location of the receiving platform.

[0016] Beneficial effects: The transfer sheet feeder provided by this utility model drives the suction cup assembly to swing between the hopper mechanism and the tape, switching the suction cup assembly between the tape and the hopper opening, thereby transferring the sheet onto the tape.

[0026] Example Reference Figure 1 As shown, this embodiment provides a transfer-type sheet feeder, including a hopper mechanism 1, a receiving platform 2, a peeling blade 6, a traction mechanism 3, and a feeding mechanism 4, and the aforementioned hopper mechanism 1, receiving platform 2, peeling blade 6, traction mechanism 3, and feeding mechanism 4 are all mounted on the housing 5.

[0027] Specifically, continue to refer to Figure 1 As shown, the hopper mechanism 1 has a hopper with an opening 11 at one end. The hopper is used to stack sheets of material with a base paper, and the sheets are fed sequentially from the opening 11. (Refer to...) Figure 2 As shown, a tape 31 is wound around the traction mechanism 3, which drives the tape 31 to move from the hopper mechanism 1 towards the receiving platform 2. (Refer to...) Figure 8 As shown, the peeling blade 6 is positioned close to the receiving platform 2, creating a gap between the peeling blade 6 and the receiving platform 2. The peeling blade 6 is used to separate the sheet material from the backing paper. The adhesive tape 31 passes through the gap between the peeling blade 6 and the receiving platform 2. As the sheet material moves with the adhesive tape, it passes through the gap between the peeling blade 6 and the receiving platform 2, thereby peeling the sheet material transported on the adhesive tape 31 from the backing paper by the peeling blade 6 and transferring it to the receiving platform 2, thus achieving sheet material feeding.

[0028] Specifically, refer to Figure 3 As shown, the feeding mechanism 4 includes a mounting base 41, a swing arm 42, a drive assembly 43, a suction cup assembly 44, and a tilting assembly. The swing arm 42 is rotatably mounted on the mounting base 41, which is mounted on the housing 5. The drive assembly 43 is connected to the swing arm 42, and the suction cup assembly 44 is connected to the swing arm 42. The drive assembly 43 drives the swing arm 42 to rotate, while the drive suction cup assembly 44 swings between the hopper and the conveyor belt 31. The drive assembly 43 can be a rotary cylinder or a motor.

[0029] The flipping component is connected to the suction cup component 44, changing the orientation of the suction cup component 44 as it swings between the hopper and the tape 31. During the swinging process between the hopper and the tape 31, the driving component 43 drives the suction cup component 44, and the flipping component changes the orientation of the suction cup component 44. This allows the suction cup component 44 to flip towards the opening 11 of the hopper when it swings close to the hopper, thus adsorbing the sheet material at the opening 11. Similarly, when the suction cup component 44 moves close to the tape 31, it flips towards the opening 11 of the hopper, thus adhering the sheet material to the tape 31.

[0030] The sheet feeder provided in this embodiment drives the suction cup assembly 44 to swing between the hopper mechanism 1 and the tape 31, causing the suction cup assembly 44 to switch between facing the tape 31 and the hopper opening 11, thereby transferring the sheet onto the tape 31. The sheet moves with the tape 31 to between the peeling blade 6 and the receiving platform 2, where it is peeled off from the backing paper by the peeling blade 6 and moved to the receiving platform 2 for feeding. There is no need to leave a blank space on the backing paper, and the feeding and peeling are divided into two independent stages, without waiting for the previous sheet to be peeled off, enabling continuous feeding and improving the feeding efficiency.

[0031] Specifically, refer to continue referring to Figure 3 As shown, the flipping assembly includes an auxiliary arm 45, a rotating block 46, and a guide shaft 47. The auxiliary arm 45 is mounted on a mounting base 41. The rotating block 46 is rotatably mounted on the auxiliary arm 45 and has a through hole. The guide shaft 47 movably passes through the through hole, and one end is connected to the suction cup assembly 44. During the movement of the swing arm 42, the suction cup assembly 44 can flip under the combined action of the auxiliary arm 45, the rotating block 46, and the guide shaft 47. In this embodiment, a limiting block 48 is also provided at the end of the guide shaft 47 away from the suction cup assembly 44. The limiting block 48 is used to prevent the guide shaft 47 from disengaging from the rotating block 46.

[0032] It should be noted that the suction cup assembly 44 can adsorb or release the sheet material, and the specific structure and control method of the suction cup assembly 44 can be selected from the existing technology, which will not be described in detail in this embodiment.

[0033] Specifically, refer to Figure 1 and Figure 4 As shown, the mounting base 41 is mounted on the housing 5 via an adjustment assembly. The adjustment assembly allows for adjustment of the X and Z directions of the mounting base 41, thereby adjusting the position of the suction cup assembly 44. This enables the suction cup assembly 44 to accurately pick up the sheet material in the hopper and accurately transfer it onto the conveyor belt 31. It should be noted that in this application, the X direction refers to the direction in which the conveyor belt 31 moves from the hopper mechanism 1 towards the receiving platform 2.

[0034] Specifically, the adjustment assembly includes a first adjustment plate 411 and a second adjustment plate 412. The first adjustment plate 411 has a first waist-shaped groove 413 extending along a first direction, and the first adjustment plate 411 is connected to the second adjustment plate 412 through the first waist-shaped groove 413 by a first connecting bolt. The second adjustment plate 412 has a second waist-shaped groove 414 extending along a second direction, and the second adjustment plate 412 is connected to the housing 5 through the second waist-shaped groove 414 by a second connecting bolt. The first direction is perpendicular to the second direction. The first direction is the Z-direction, and the second direction is the X-direction.

[0035] Specifically, the rotation axis of the swing arm 42, the rotation axis of the suction cup assembly 44, and the rotation axis of the guide block are parallel to each other.

[0036] Specifically, when the suction cup assembly 44 faces the hopper opening 11 or the tape 31, the distance from the rotation axis of the guide block to the rotation axis of the suction cup assembly 44 is equal to the distance from the rotation axis of the swing arm 42 to the rotation axis of the suction cup assembly 44. (Refer to...) Figure 5 As shown, when the suction cup assembly 44 swings toward the tape 31, the suction cup assembly 44 and the guide shaft 47 are arranged vertically. Figure 5 Point A is the projection point of the rotation axis of the guide block, point C1 is the projection point of the rotation axis of the suction cup assembly 44, and point B is the projection point of the rotation axis of the swing arm 42. In this state, AC1 = BC1. (Refer to...) Figure 6 As shown, when the suction cup assembly 44 swings toward the hopper, the suction cup assembly 44 and the guide shaft 47 are arranged horizontally, and point C2 is the projection point of the rotation axis of the suction cup assembly 44. In this state, AC2=BC2.

[0037] Specifically, refer to Figure 7 As shown, the hopper mechanism 1 includes multiple hopper units 12, a hopper base plate 13, and a hopper drive component 14. The hopper units 12 are movably mounted on the hopper base plate 13 along a third direction, and the multiple hopper units 12 are arranged in a third direction. The hopper drive component 14 is connected to the hopper units 12 and is used to drive the hopper units 12 to move along a third direction. In this embodiment, two hopper units 12 are provided. By driving the hopper units 12 to move through the hopper drive component 14, different hopper units 12 can be switched to align with the suction cup assembly 44. Thus, when the sheet material in one hopper unit 12 is loaded, the process can be switched to the other hopper unit 12 for loading. It should be noted that in this embodiment, the hopper units 12 are detachably connected to the hopper base plate 13.

[0038] Specifically, a sensor 15 is also provided on the bottom plate 13 of the hopper. The sensor 15 is used to monitor whether there are still pieces of material in the hopper unit 12. When there are no more pieces of material, the next hopper unit 12 can be switched.

[0039] Specifically, the edge of the opening 11 of the hopper unit 12 is provided with a baffle 16, which is used to prevent the sheet material from falling naturally. After the suction cup assembly 44 adsorbs the sheet material in the hopper unit 12, it moves under the action of the drive assembly 43 and the flipping assembly and pulls the sheet material out of the hopper unit 12.

[0040] Specifically, a counterweight is provided at the end of the hopper furthest from the opening 11; the hopper is arranged at an angle, and the end with the counterweight is higher than the end with the opening 11; multiple sheets are stacked inside the hopper, with the counterweight pressing down on the last sheet furthest from the opening 11. When a sheet is picked up by the suction cup assembly 44, the angled hopper, in conjunction with the counterweight, can automatically push the sheet to the opening 11 for easy picking up again.

[0041] In this embodiment, the plane of the hopper opening 11 is perpendicular to the plane of the tape 31 where the sheet adheres to the tape 31, so that when the suction cup assembly 44 rotates to face the hopper, the suction cup assembly 44 can be directly facing the sheet.

[0042] Specifically, refer to Figure 2 As shown, the traction mechanism 3 includes a tape reel 32 and a waste reel 33. One end of the tape 31 is wound around the tape reel 32, and the other end is wound around the waste reel 33 after passing the location of the receiving platform 2. A traction motor 34 is connected to the waste reel 33 for transmission. The traction motor 34 drives the waste reel 33 to rotate, which in turn drives the tape 31 to move, so that the tape 31 is continuously fed to the receiving platform 2.

[0043] Work process: The traction mechanism 3 drives the tape 31 to move, so that the tape 31 continuously feeds the material to the receiving platform 2. When the sheet moves to the position of the peeling knife 6 at the receiving platform 2, the sheet is separated from the backing paper under the action of the peeling knife 6, and the sheet continues to move to the receiving platform 2 to realize the feeding.

[0044] During the continuous feeding of the tape 31, the drive assembly 43 drives the swing arm 42 to swing, and at the same time, the position and orientation of the suction cup assembly 44 are changed under the action of the flipping assembly, so that the suction cup assembly 44 moves to face the opening 11 of the hopper or to face the tape 31; when the suction cup assembly 44 faces the opening 11 of the hopper, it adsorbs the sheet material in the hopper; when the suction cup assembly 44 faces the tape 31, it releases the sheet material and adheres it to the tape 31; thus, the feeding and peeling of the backing paper are independent of each other, and continuous feeding of sheet material can be realized.

[0045] When sensor 15 detects that there are no pieces in hopper unit 12, it can drive hopper unit 12 to move through hopper drive component 14, thereby switching to another hopper unit 12.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
