Description

Technical Field

[0001] The utility model relates to the technical field of button vehicle button production, in particular to a button blank feeding device and a button vehicle machine. Background Art

[0002] With the development of button vehicle manufacturing technology, automatic feeding technology has emerged, which has the characteristics of improving production efficiency and reducing manual operation, and can greatly improve the working efficiency of the button vehicle machine. However, the current automatic feeding methods are mainly applicable to the feeding of cylindrical button blanks, and these devices can only identify the front and back sides of the button blanks and cannot fix the direction of the button blanks during feeding.

[0003] In traditional technology, cylindrical button blanks are fed through a vibrating bowl. The vibrating bowl uses the inclination of the track and the baffle to ensure the single arrangement of the button blanks, and through a simple front and back identification system, the button blanks are conveyed to the processing part of the button vehicle machine. However, currently, the button blanks of multi-layer buttons are square, have two or more color layers, and the button holes are parallel to the color layers, and the feeding device of the button vehicle machine cannot fix the direction of the button blanks for feeding. Therefore, during the production of multi-layer buttons by the button vehicle machine, manual feeding is used to feed the buttons into the button clamping head of the button vehicle machine. The manual feeding speed is about 10 pieces per minute, and the feeding efficiency is low. Summary of the Utility Model

[0004] Based on this, in view of the problem that the feeding direction of the button blanks of multi-layer buttons cannot be fixed, it is necessary to provide a button blank feeding device and a button vehicle machine.

[0005] In a first aspect, the present application discloses a button blank feeding device, which includes:

[0006] A feeding assembly, including a vibrating bowl and a feeding track; the feeding track spirally ascends along the inner side wall of the vibrating bowl and inclines towards the edge of the vibrating bowl for removing overlapping button blanks;

[0007] An identification assembly, arranged at the end of the feeding track for identifying the direction of the button blanks.

[0008] In one embodiment, the feeding assembly further includes an identification track, which is horizontally arranged and connected to the end of the feeding track.

[0009] In one embodiment, the vibrating bowl includes:

[0010] A first vibrating part, which is cylindrical, and the feeding track is connected to the inner side wall of the first vibrating part;

[0011] A second vibrating part, which is cuboid, there is an intersection area between the second vibrating part and the first vibrating part, and there is no side wall in the intersection area; the side wall of the second vibrating part protrudes from the side wall of the first vibrating part.

[0012] In one embodiment, the loading track includes a first loading part and a second loading part; the second loading part is a straight track located in the second vibrating part, and there is a gap between the second loading part and the inner side wall of the second vibrating part.

[0013] In one embodiment, a first baffle is provided on one side of the second loading part close to the second vibrating part, and the height of the first baffle is 1 mm.

[0014] In one embodiment, the identification assembly includes:

[0015] A color mark sensor, located on the identification track, for identifying the direction of the button blanks;

[0016] A button blowing air pipe, arranged adjacent to the color mark sensor, for blowing the button blanks with incorrect directions back into the vibrating disk.

[0017] In one embodiment, the identification track includes:

[0018] A second baffle, arranged on the side of the identification track away from the vibrating disk; the second baffle is provided with a through hole for passing through the button blowing air pipe;

[0019] A third baffle, arranged opposite to the second baffle, and the third baffle is not provided on the part of the identification track relative to the button blowing air pipe.

[0020] In one embodiment, the color mark sensor is connected to the identification track through a connecting bracket, and the connecting bracket is used to adjust the position of the color mark sensor.

[0022] In a second aspect, a button attaching machine of the present application includes a button blank loading device as in any one of the embodiments of the first aspect.

[0023] The above-mentioned button blank loading device and button attaching machine combine a vibrating disk with a spirally rising loading track to realize the automatic arrangement and transportation of button blanks. The loading track spirally rises along the inner side wall of the vibrating disk and inclines towards the edge, and uses gravity to naturally remove the button blanks stacked together, ensuring that only single button blanks can rise along the track, effectively avoiding multiple button blanks entering the processing link at the same time and avoiding processing errors caused by overlapping; the identification assembly provided at the end of the loading track identifies the direction of the button blanks and removes the button blanks with incorrect directions, avoiding button blanks with incorrect directions from entering the subsequent processing link, and can perform precise direction identification and single arrangement for the special shape and structure of square button blanks, so as to improve the production efficiency of the button attaching machine and reduce the defective rate.

[0038] The applicant noticed that as Figure 1 shown, the square button blank of the multi-layer button has two or more color layers, and the button hole is parallel to the color layer. If the direction cannot be fixed during the feeding process, it will lead to processing errors and a large number of defective products. However, the traditional automatic feeding device cannot ensure the correct direction of the button blank when processing the square button blank of the multi-layer button.

[0039] Referring to Figure 2 , Figure 2 FIG. shows a schematic structural diagram of a button blank feeding device in an embodiment of the present invention. An embodiment of the present invention provides a button blank feeding device, which includes a feeding assembly and an identification assembly; the feeding assembly includes a vibrating disk 10 and a feeding track. The feeding track spirally rises along the inner side wall of the vibrating disk 10 and inclines towards the edge of the vibrating disk 10 for removing overlapping button blanks; the identification assembly is arranged at the end of the feeding track for identifying the direction of the button blank.

[0040] Specifically, the feeding assembly includes a vibrating disk 10 and a feeding track. The vibrating disk 10 is of a cylindrical structure. The starting end of the feeding track is connected to the bottom of the vibrating disk 10, and the side surface of the feeding track is tightly connected to the inner side wall of the vibrating disk 10 and spirally rises along the inner side wall of the vibrating disk 10. The vibrating disk 10 vibrates to make the square button blanks on the bottom surface of the vibrating disk 10 move along the feeding track inside the disk. And one side of the feeding track close to the center of the vibrating disk 10 is higher than the side far from the center. Due to the vibration and gravity, when the square button blanks move on the track, the overlapping button blanks will slide off the track under the action of gravity, and only a single button blank can continue to rise along the track. The width of the feeding track is slightly larger than the outer dimension of the square button blank. The end of the feeding track is connected to the identification assembly. The identification assembly is used to identify the direction of the square button blank. As Figure 1 shown, the button hole of the square button blank is parallel to the color layer. By identifying the color layer direction of the square button blank, the direction of the direction button blank is further identified, and the button blanks with incorrect directions are removed to avoid the button blanks with incorrect directions from entering the next process.

[0041] In this embodiment, by combining the vibrating disk 10 with the spirally ascending feeding track, the automatic arrangement and conveying of button blanks are realized. The feeding track spirally ascends along the inner side wall of the vibrating disk 10 and inclines towards the edge, and the button blanks stacked together are naturally removed by gravity, ensuring that only a single button blank can ascend along the track, effectively avoiding multiple button blanks entering the processing link simultaneously and avoiding processing errors caused by overlapping; by the recognition component arranged at the end of the feeding track, the direction of the button blank is recognized, and the button blanks with incorrect directions are removed, preventing button blanks with incorrect directions from entering the subsequent processing link, and being able to perform precise direction recognition and single arrangement for the special shape and structure of square button blanks, so as to improve the production efficiency of the button lathe 30 and reduce the defective rate.

[0042] Please continue to refer to Figure 2 and in combination with Figure 3 , Figure 3 FIG. shows a schematic structural diagram of a button blank feeding device in an embodiment of the present invention. In some embodiments, the vibrating disk 10 includes a first vibrating part 102 and a second vibrating part 104, and the feeding track includes a first feeding part 204 and a second feeding part 206.

[0043] Specifically, the vibrating disk 10 includes a first vibrating part 102 and a second vibrating part 104. The first vibrating part 102 is cylindrical, and the feeding track is connected to the inner side wall of the first vibrating part 102. The second vibrating part 104 is rectangular, and there is an intersecting area between the first vibrating part 102 and the second vibrating part 104, and there is no side wall in the intersecting area, that is, the inside of the vibrating disk 10 is an integral cavity; outside the vibrating disk 10, the side wall of the second vibrating part 104 protrudes from the side wall of the first vibrating part 102. The feeding track includes a first feeding part 204 and a second feeding part 206. The first feeding part 204 is tightly connected to the inner side wall of the first vibrating part 102 and spirally ascends along the inner side wall of the first vibrating part 102, and the side of the first feeding part 204 close to the center of the first vibrating part 102 is higher than the side far from the center. The second feeding part 206 is located in the second vibrating part 104 and is a straight track. The second feeding part 206 is suspended from the second vibrating part 104, that is, there is a gap between the second feeding part 206 and the inner side wall of the second vibrating part 104. The side of the second feeding part 206 close to the center of the first vibrating part 102 is higher than the side far from the center. A first baffle 208 is provided on the side of the second feeding part 206 far from the center of the first vibrating part, and the height of the first baffle 208 is close to the thickness of the square button blank.

[0044] Exemplarily, the height of the first baffle 208 is 1 mm. The vibrating disk 10 vibrates to move the square button blanks on the bottom surface of the vibrating disk 10 along the first feeding part 204 inside the disk. Due to the effects of vibration and gravity, when the square button blanks move on the first feeding part 204, the stacked button blanks will slide down from the first feeding part 204 under the action of gravity, and only single button blanks can continue to rise along the track. When the square button blanks enter the second feeding part 206 through the first feeding part 204, the square button blanks attached to the second feeding part 206 are blocked by the first baffle 208, thus entering the identification component area. By identifying the color layer direction of the square button blanks, the direction identification of the button blanks is completed, and the button blanks with incorrect directions are removed to prevent button blanks with incorrect directions from entering the next process. The overlapping square button blanks will slide down from the second feeding part 206 into the gap between the second feeding part 206 and the second vibrating part 104 and re-enter the vibrating disk 10 for the next feeding.

[0045] In this embodiment, the vibrating disk 10 is divided into a first vibrating part 102 and a second vibrating part 104, and the feeding track is divided into a first feeding part 204 and a second feeding part 206, so that the square button blanks are screened through multiple areas during the feeding process, and the overlapping button blanks slide down from the feeding track, which can be applicable to various complex working conditions and avoid the situation of stacked buttons. On the other hand, the gap between the second feeding part 206 and the second vibrating part 104 enables the stacked buttons to return to the vibrating disk 10, realizing efficient and stable feeding.

[0046] Please refer to Figure 4 and combine with Figure 3 , Figure 4 which shows a schematic structural diagram of a button machine in an embodiment of the present invention. In some embodiments, the identification component includes a color mark sensor 210 and a button blowing air pipe 212. The color mark sensor 210 is located on the identification track 202 and is used to identify the direction of the button blanks. The button blowing air pipe 212 is arranged adjacent to the color mark sensor 210 and is used to blow the button blanks with incorrect directions back into the vibrating disk 10.

[0047] Specifically, the feeding assembly further includes an identification track 202. The identification track 202 is a straight track with a gap between it and the inner wall of the vibrating disk 10. The identification track 202 is horizontally arranged and connected to the end of the feeding track. Second baffles 216 and third baffles 218 are respectively provided on both sides of the identification track 202. The second baffle 216 is located on the side of the identification track 202 away from the center of the first vibrating part 102, and the third baffle 218 is correspondingly arranged with the second baffle 216 and is located on the side close to the center of the first vibrating part 102. The color mark sensor 210 is located on the identification track 202 and is connected to the identification track 202 through a connecting bracket 214. The blowing button air pipe 212 is arranged adjacent to the color mark sensor 210 and is used to blow the direction buttons with incorrect directions back into the vibrating disk 10. The part of the side of the identification track 202 close to the center of the first vibrating part 102 relative to the blowing button air pipe 212 and the color mark sensor 210 is not provided with the third baffle 218 to ensure that the blowing button air pipe can smoothly blow the buttons with incorrect directions back into the vibrating disk 10.

[0048] Exemplarily, when the direction buttons passing through the second vibration area enter the identification track 202, the color mark sensor 210 identifies the direction of the direction buttons. When the moving direction of the multi-layer button blanks is parallel to the color layer, the color mark sensor 210 only identifies one of the outermost two color layers, and the color mark sensor 210 will not generate an electrical signal. When the moving direction of the multi-layer button blanks is perpendicular to the color layer, the color mark sensor 210 will simultaneously detect the middle color layer, and the color mark sensor 210 will generate an electrical signal. When there are only two color layers in the multi-layer button, when the color mark sensor 210 detects color layer one, the color mark sensor 210 will not generate an electrical signal. When the color mark sensor 210 detects color layer two, the color mark sensor 210 will generate an electrical signal. The electrical signal is transmitted to the relay, and the control solenoid valve will be activated. High-pressure gas is ejected from the blowing button air pipe 212 to blow the buttons with incorrect directions into the vibrating disk 10.

[0049] In this embodiment, by arranging the color mark sensor 210 and the blowing button air pipe 212 on the identification track 202, buttons with incorrect directions can be effectively identified and corrected. The color mark sensor 210 can accurately detect the direction of the button blanks. When the direction of the button blanks is incorrect, the blowing button air pipe 212 is triggered by an electrical signal to blow it back into the vibrating disk 10, thereby preventing the square button blanks with incorrect directions from entering the discharging track 106. This design significantly reduces the generation of defective products during the production process and improves the feeding accuracy and product consistency.

[0050] In some embodiments, the button blank feeding device further includes a discharging track 106. The discharging track 106 is connected to the feeding assembly. The discharging track 106 is a semi-closed track and is used to transmit the button blanks to the button clamping faucet.

[0051] Exemplarily, before using the button blank feeding device, let the color mark sensor 210 record one of the color layers of the multi-layer button square blanks with two color layers or record one of the color layers in the middle of the multi-layer buttons with more than two color layers. Then place the square button blank horizontally and in contact with the second baffle 216 with the color mark sensor 210, and adjust the color mark sensor 210 to align with the outermost color layer. Start the button blank feeding device, and the square button blanks in the vibrating disk 10 move along the feeding track of the vibrating disk 10. When the square button blank passes through the second feeding part 206, the button blanks stacked on the square button blank and the erected button blanks will fall back into the vibrating disk 10. After the square button blank passes through the second feeding part 206, the color mark sensor 210 will identify the color on the button stacking and exclusion track. When the square button blank is perpendicular to the moving direction, the color mark sensor 210 detects the corresponding color and generates an electrical signal, and the button blowing air pipe 212 blows out high-pressure air to blow the square button blank with the wrong direction back into the vibrating disk 10. When the square button blank is parallel to the moving direction, the color mark sensor 210 cannot detect the corresponding color and cannot generate an electrical signal. The multi-layer button square button blank moves to the discharging track 106, and the square button blank is sent to the feeding device of the button sewing machine 30, and the feeding device of the button sewing machine 30 sends the multi-layer button square button blank to the button clamping faucet 20 of the button sewing machine 30, completing the feeding of the square button blank of the button sewing machine 30.

[0052] In this embodiment, the discharging track 106 is configured as a semi-closed track, which can effectively convey the button blanks in the correct direction from the feeding assembly to the button clamping faucet 20 of the button sewing machine 30. Combining the designs of the vibrating disk 10, the color mark sensor 210, the button blowing air pipe 212 and the discharging track 106, the efficient and automatic conveying of the button blanks is realized; by accurately identifying and removing the button blanks with the wrong direction and the optimized structure of the discharging track 106, the production defects caused by the wrong direction are reduced, and the defective products and material waste caused by the assembly errors are reduced.

[0053] In some embodiments, the button sewing machine provided by the present invention includes the button blank feeding device in any other embodiment.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should be considered as the scope recorded in this specification.

[0055] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent.
