Description

Technical Field

[0001] This utility model relates to the field of garment processing equipment technology, and in particular to a label positioning device. Background Technology

[0002] Labels are used to identify clothing information. When sewing labels onto clothing, precise label positioning is required. There are usually two ways to receive labels: the first is by rolling up label tape, which needs to be cut into individual labels before loading; the second is by stacking multiple labels together, where the labels need to be positioned before being moved to the sewing position on the clothing. Current label loading devices typically involve manually aligning multiple labels and placing them in a loading box, then a transport module moves the labels from the loading box to the sewing position one by one. However, manually aligning labels results in very low positioning accuracy, leading to low precision in both label loading and sewing positions on the clothing. This is especially true when multiple different labels need to be stacked and sewn onto clothing, resulting in uneven positions of the labels at the sewing position and low alignment accuracy, leading to poor garment processing quality and aesthetics. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a label positioning device for accurately positioning labels, thereby achieving accurate and rapid label loading.

[0004] A label positioning device according to an embodiment of the present invention includes a base plate, a positioning plate, a conveying mechanism, and a vibrator. The base plate has multiple hoppers distributed along a left-right direction, each hopper holding multiple stacked labels. The rear end of the positioning plate is hinged to the base plate, and the positioning plate is tiltable forward. The upper surface of the positioning plate has multiple positioning grooves distributed along a left-right direction, and the inner front wall of each positioning groove is a positioning wall. The conveying mechanism is used to convey the topmost label from the hoppers into the positioning grooves. The vibrator is mounted on the positioning plate and forces the positioning plate to vibrate, thereby aligning the labels in the positioning grooves with the positioning walls.

[0005] It has at least the following beneficial effects: Multiple stacked labels are placed in the hopper, and then the topmost label in the hopper is transported to the positioning slot by the conveying mechanism. Then, the vibrator is activated, which forces the positioning plate to vibrate. Since the positioning plate is tilted forward, the label in the positioning slot is aligned with the positioning wall, completing the precise positioning of the label. This allows the conveying module to quickly and accurately grab the label and feed it to the sewing equipment. When multiple stacked labels are placed in the hopper, there is no need to manually align them. The label positioning device achieves precise label positioning and supplies the material to the conveying module, increasing the label feeding speed, reducing the workload of workers, and improving the accuracy of label feeding to the sewing position.

[0009] According to some embodiments of the present invention, the conveying mechanism includes a front and rear drive mechanism, a first lifting drive mechanism, and a suction nozzle. The front and rear drive mechanism and the first lifting drive mechanism are respectively used to drive the suction nozzle to move in the front-rear direction and the up-down direction, so that the suction nozzle can transport the topmost label on the hopper to the positioning groove.

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] Reference Figures 1 to 3 This utility model discloses a label positioning device, including a base plate 1, a hopper 2, a positioning plate 3, a conveying mechanism 5, and a vibrator 6. The base plate 1 is provided with multiple hoppers 2 distributed in the left-right direction, and the hoppers 2 are used to hold multiple stacked labels. The rear end of the positioning plate 3 is hinged to the base plate 1, and the positioning plate 3 can tilt forward. The upper surface of the positioning plate 3 is provided with multiple positioning grooves 4, which are distributed in the left-right direction. The front inner wall of the multiple positioning grooves 4 is a positioning wall. The conveying mechanism 5 is used to convey the topmost label on the hopper 2 into the positioning groove 4. The vibrator 6 is provided on the positioning plate 3, and the vibrator 6 is used to force the positioning plate 3 to vibrate so that the label in the positioning groove 4 is aligned with the positioning wall.

[0021] Initially, multiple stacked labels are placed in the hopper 2. Then, the conveying mechanism 5 moves the top label from the hopper 2 into the positioning slot 4. Next, the vibrator 6 is activated, which forces the positioning plate 3 to vibrate. Since the positioning plate 3 is tilted forward, the label in the positioning slot 4 is aligned with the positioning wall, thus completing the precise positioning of the label. This allows the conveying module to quickly and accurately grab the label and feed it to the sewing equipment, ensuring the accuracy of the label's sewing position on the garment.

[0022] Multiple hoppers 2 are used to hold various labels, enabling the label positioning device to position and feed various labels. It can not only feed one type of label to the sewing position one by one to complete the sewing of a single label onto the garment, but also feed multiple labels sequentially to the same sewing position one by one to complete the neat sewing of multiple labels onto the garment, ensuring the positional accuracy of the fed labels.

[0023] When placing multiple stacked labels on the hopper 2, there is no need to manually align the multiple stacked labels. The label positioning device achieves precise positioning of the labels and supplies materials to the handling module, thereby increasing the label feeding speed, reducing the workload of workers, and improving the accuracy of label feeding to the sewing position.

[0024] Reference Figure 3 or Figure 4 The length of the positioning plate 3 is parallel to the left and right directions. The positioning plate 3 is located in front of multiple hoppers 2. Multiple positioning slots 4 are located in front of multiple hoppers 2 respectively. The multiple positioning slots 4 and multiple hoppers 2 correspond one-to-one. The conveying mechanism 5 drives the label to rise first, then the label moves forward to the top of the positioning slot 4, and then the label moves down into the positioning slot 4.

[0025] Reference Figure 3 In some embodiments, a linear drive mechanism 7 is hinged to the base plate 1. The output end of the linear drive mechanism 7 is hinged to the front end of the positioning plate 3. The output end of the linear drive mechanism 7 can drive the positioning plate 3 to swing around the left and right directions as the rotation center, that is, adjust the tilt angle of the positioning plate 3. The positioning plate 3 is kept in a forward tilted state, that is, the front end of the positioning plate 3 is lower than the rear end of the positioning plate 3, the front end of the positioning groove 4 is lower than the rear end of the positioning groove 4, and the front inner wall of the positioning groove 4 is also in a forward tilted state. When the side walls of the positioning plate 3 and the positioning groove 4 vibrate, the front end of the label can be aligned with the front inner wall of the positioning groove 4.

[0026] When the label is placed in the positioning groove 4, the vibrator 6 is started. At this time, the front end of the positioning plate 3 can be swung downward by the linear drive mechanism 7, which is more conducive to quickly pressing the front end of the label against the inner wall of the positioning groove 4, improving the positioning efficiency of the label in the positioning groove 4, and further ensuring the positioning accuracy of the label in the positioning groove 4. After a certain time interval, the front end of the positioning plate 3 can be swung upward by the linear drive mechanism 7, so that the positioning plate 3 and the positioning groove 4 are reset, so that the label in the positioning groove 4 can be removed or another label can be put into the positioning groove 4.

[0027] Rotating shafts are connected to the rear sides of the left and right ends of the lower surface of the positioning plate 3. The length direction of the two rotating shafts is parallel to the left and right direction, and the two rotating shafts are coaxially arranged. Each rotating shaft is equipped with a bearing, and the two bearings are connected to the base plate 1 through two bearing seats. Two linear drive mechanisms 7 are hinged to the base plate 1. The output ends of the two linear drive mechanisms 7 are respectively hinged to the front sides of the left and right ends of the positioning plate 3. The two linear drive mechanisms 7 can make the left and right ends of the positioning plate 3 balanced.

[0028] Reference Figure 5 In some embodiments, a support column 11 is provided on the base plate 1, and a limit column is threadedly connected to the support column 11. The height of the limit column can be adjusted by rotating the limit column. The lower end of the limit column is used to abut against the upper surface of the positioning plate 3. The limit column limits the tilt angle of the positioning plate 3 to prevent the positioning plate 3 from tilting backward and to ensure that the label is aligned with the front inner wall of the positioning groove 4.

[0029] It should be noted that the position of the limiting post is in front of the rotating shaft, so that when the front end of the positioning plate 3 swings, the limiting post can abut against the front end of the positioning plate 3, that is, the limiting post can abut against the free end of the positioning plate 3.

[0030] Reference Figure 4 In some embodiments, the positioning plate 3 is provided with a front positioning block 31, a left positioning block 32 and a right positioning block 33, which form a positioning groove 4. The front positioning block 31, the left positioning block 32 and the right positioning block 33 respectively limit the left position, the right position and the front position of the label on the positioning plate 3, thereby positioning the left and right positions of the label so that the label is aligned with the front positioning block 31.

[0031] The rear ends of the left positioning block 32 and the right positioning block 33 are each provided with a first chamfer on their opposite sides, forming a first V-shaped opening. The first V-shaped opening gradually narrows from back to front. When the positioning plate 3 tilts forward, it can guide the label to move from back to front into the positioning groove 4 and abut against the front inner wall of the positioning groove 4. The rear ends of the left positioning block 32 and the right positioning block 33 are each provided with a second chamfer on their opposite sides, forming a second V-shaped opening. The second V-shaped opening gradually narrows from top to bottom. When the label moves down, the second V-shaped opening can guide the label to move from top to bottom into the positioning groove 4 and abut against the bottom wall of the positioning groove 4.

[0032] Reference Figure 4 The multiple positioning slots 4 include a front positioning block 31, multiple left positioning blocks 32 and multiple right positioning blocks 33, and a region of a left positioning block 32, a right positioning block 33 and a front positioning block 31 forms a positioning slot 4.

[0033] The positions of the left positioning block 32 and the right positioning block 33 on the positioning plate 3 are adjustable, thereby adjusting the position of the positioning groove 4 in the left-right direction and also adjusting the width of the positioning groove 4 in the left-right direction, so that the positioning groove 4 can be used for labels of different widths. It should be noted that both the left positioning block 32 and the right positioning block 33 are provided with a third elongated hole, the length direction of which is parallel to the left-right direction. A third fastener is threaded onto the positioning plate 3, and the third fastener passes through the third elongated hole. Tightening the third fastener can fix the left positioning block 32 / right positioning block 33 on the positioning plate 3, while loosening the third fastener can adjust the left-right position of the left positioning block 32 / right positioning block 33 on the positioning plate 3.

[0034] Reference Figure 1 or Figure 2 or Figure 5 In some embodiments, the conveying mechanism 5 includes a front and rear drive mechanism 51, a first lifting drive mechanism 52, and a suction nozzle 53. The front and rear drive mechanism 51 and the first lifting drive mechanism 52 are respectively used to drive the suction nozzle 53 to move in the front-back direction and the up-down direction, so that the suction nozzle 53 can transport the top label on the hopper 2 to the positioning groove 4.

[0035] Reference Figure 2 In some embodiments, the output end of the first lifting drive mechanism 52 is provided with a guide frame 521. The first lifting drive mechanism 52 is used to drive the guide frame 521 to rise and fall. The guide frame 521 is provided with a guide rod 54. The guide frame 521 is used to guide the guide rod 54 to rise and fall. The upper end of the guide rod 54 is provided with a limiting block 541 for abutting against the guide frame 521. The limiting block 541 limits the maximum stroke of the guide rod 54 relative to the guide frame 521. The suction nozzle 53 is provided at the lower end of the guide rod 54. An elastic element 55 is provided between the guide frame 521 and the suction nozzle 53. The elastic element 55 forces the suction nozzle 53 to move downward, so that in the natural state, the guide rod 54 and the suction nozzle 53 are in a suspended state, the suction nozzle 53 is in a position away from the guide frame 521, and the limiting block 541 abuts against the guide frame 521.

[0036] Initially, the first lifting drive mechanism 52 drives the guide frame 521 to rise to a high position, placing the guide rod 54 and the suction nozzle 53 at a higher position, with the suction nozzle 53 above the hopper 2. When the conveying mechanism 5 operates, the first lifting drive mechanism 52 drives the guide frame 521 to descend. The guide frame 521 carries the guide rod 54 and the suction nozzle 53 down. When the suction nozzle 53 touches the label on the hopper 2, the guide rod 54 and the suction nozzle 53 stop descending, and the elastic element 55 is compressed until the guide frame 521 moves down to a low position, and the suction nozzle 53 picks up the label on the hopper 2. Then, the first lifting drive mechanism 52 drives the guide frame 521 to rise to a high position again, and the elastic element 55 is compressed until the guide frame 521 moves down to a low position, and the suction nozzle 53 picks up the label on the hopper 2. The elastic element 55 is reset to its extended state, the guide rod 54 and the suction nozzle 53 are in a higher position, and the suction nozzle 53 and the label adsorbed on the suction nozzle 53 are above the hopper 2; then the front and rear drive mechanism 51 drives the suction nozzle 53 to move above the positioning groove 4, so that the label adsorbed on the suction nozzle 53 is facing the positioning groove 4; then the first lifting drive mechanism 52 drives the guide frame 521 to descend again. The guide frame 521 carries the guide rod 54 and the suction nozzle 53 down. When the label on the suction nozzle 53 touches the bottom of the positioning groove 4, the elastic element 55 is compressed again until the guide frame 521 moves down to the lower position again, the suction nozzle 53 releases the label, and the label is placed in the positioning groove 4.

[0037] Since both the guide rod 54 and the suction nozzle 53 can be raised or lowered relative to the output end of the first lifting drive mechanism 52 or the guide frame 521, and the elastic element 55 can force the suction nozzle 53 to move downward relative to the guide frame 521, the stroke of the first lifting drive mechanism 52 driving the guide frame 521 to rise or fall remains unchanged each time, and the suction nozzle 53 can transport labels of all heights in the hopper 2 to the positioning slot 4.

[0038] Reference Figure 2 In some embodiments, the suction nozzle 53 is connected to the guide rod 54, and an air passage 542 is provided at the central axis of the guide rod 54. The suction nozzle 53 is connected to the air passage 542, and the air passage 542 is connected to an external negative pressure device, so that negative pressure can be generated at the suction nozzle 53, thereby enabling the suction nozzle 53 to adsorb the label.

[0039] The elastic element 55 is a spring, which is sleeved on the lower end of the guide rod 54, and the two ends of the spring abut against the guide frame 521 and the suction nozzle 53 respectively.

[0040] It should be noted that a support plate is provided on the base plate 1, and a sliding frame 12 that moves in the front-to-back direction is provided on the support plate. The first lifting drive mechanism 52 is provided on the sliding frame 12, and the output end of the front-to-back drive mechanism 51 is connected to the sliding frame 12 or the first lifting drive mechanism 52. For details, refer to... Figure 1The transport mechanism 5 includes a front and rear drive mechanism 51, multiple first lifting drive mechanisms 52 and multiple suction nozzles 53. The multiple first lifting drive mechanisms 52 and multiple suction nozzles 53 cooperate with each other. The multiple first lifting drive mechanisms 52 are arranged sequentially on the sliding frame 12 in the left and right directions, so that the transport mechanism 5 can transport multiple labels at the same time.

[0041] Reference Figure 5 In some embodiments, the label positioning device further includes a second lifting drive mechanism 8 and multiple pressure rods 9. The second lifting drive mechanism 8 is used to drive the multiple pressure rods 9 to rise and fall, so that the multiple pressure rods 9 press multiple labels from the opening of the positioning groove 4 into the positioning groove 4, ensuring that the labels can abut against the bottom of the positioning groove 4, thus completing the label positioning.

[0042] There are two second lifting drive mechanisms 8, which are distributed left and right. The output ends of the two second lifting drive mechanisms 8 are connected to the same first horizontal plate. The first horizontal plate and the base plate 1 are parallel to each other. The first horizontal plate is parallel to the left and right direction. The two second lifting drive mechanisms 8 are connected to multiple pressure rods 9 through the first horizontal plate. The multiple pressure rods 9 move in the left and right direction.

[0043] Reference Figure 2 The sliding frame 12 has longitudinal plates connected to both its left and right ends. The two longitudinal plates are connected to the same second horizontal plate, which is parallel to the base plate 1 and parallel to the left and right directions. Two second lifting drive mechanisms 8 are located at both ends of the second horizontal plate. The distance between the suction nozzle 53 and the pressure rod 9 is equal to the distance between the hopper 2 and the positioning groove 4. The suction nozzle 53 and the pressure rod 9 move synchronously in the front-back direction without interfering with each other.

[0044] Reference Figure 4 In some embodiments, the hopper 2 includes a front baffle 21, a left side plate 22, a right side plate 23 and a rear baffle 24, all disposed on the base plate 1. The front baffle 21, the left side plate 22, the right side plate 23 and the rear baffle 24 form a limiting cavity for accommodating labels, thereby limiting the multiple stacked labels so that the conveying mechanism 5 can sequentially convey the multiple labels in the limiting cavity to the positioning groove 4 from top to bottom.

[0045] In some embodiments, the bottom of the left side plate 22 and the right side plate 23 are provided with a first elongated hole, the length direction of the first elongated hole is parallel to the left and right direction, and the bottom plate 1 is threaded with two first fasteners, which are respectively inserted through the two first elongated holes. The bottom of the rear baffle 24 is provided with a second elongated hole, the length direction of the second elongated hole is parallel to the left and right direction, and the bottom plate 1 is threaded with a second fastener, which is inserted through the second elongated hole.

[0046] Loosening the two first fasteners allows adjustment of the left side plate 22 and right side plate 23 in the left-right direction, while loosening the second fastener allows adjustment of the rear baffle 24 in the front-back direction, thereby adjusting the position of the hopper 2 and making the hopper 2 suitable for limiting labels of different lengths and widths.

[0047] The linear drive mechanism 7, the front and rear drive mechanism 51, the first lifting drive mechanism 52, and the second lifting drive mechanism 8 can all be cylinders or lead screw moving pairs. The first fastener, the second fastener, and the third fastener can be the first bolt, the second bolt, and the third bolt, respectively. The limiting post can be the fourth bolt.

[0048] 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.

[0049] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
