Description

Technical Field

[0001] The present invention relates to the technical field of washable labels, in particular to an automatic welding machine for washable labels. Background Art

[0002] Care labels are primarily used in the apparel, home textile, and luggage industries. They primarily record parameters such as the fabric, composition, and care instructions for a garment. Some labels are constructed by sewing multiple labels with various parameters onto each other. However, the process of stacking these labels is primarily manual. This stacking method is costly, inefficient, and unsuitable for production.

[0003] Chinese patent publication number CN110980255B discloses a fully automatic care label machine that addresses the low efficiency of existing care label production and delivery. It includes a machine base, a material removal device, a compound machine, a moving assembly, a cutting mechanism, a clamping mechanism, a discard box, a weighing mechanism, a weighing plate, a turning and clamping mechanism, a discard mechanism, and a conveyor assembly. The material receiving mechanism rotates relative to the material storage mechanism, while a gripping mechanism grabs all care labels from the primary or secondary material boxes and places them into the rotated, aligned material receiving box. After the material receiving mechanism rotates one full revolution relative to the material storage mechanism, the gripping mechanism draws care labels of varying specifications from the storage mechanism into the same receiving box.

[0004] However, the aforementioned care label machines and existing care label machines still have the following problems: 1. They cannot automatically weld the care labels stacked by the loading device; 2. When automatically stacking care labels, the labels cannot be stacked neatly, which affects the subsequent ultrasonic welding effect; 3. When automatically stacking care labels, the loading device cannot stack multiple care labels at a time, resulting in a need for improved production efficiency. Therefore, there is a need for an automatic care label welding machine to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to overcome the problems of the prior art and provide an automatic welding machine for washable labels.

[0006] In order to achieve the above object, the present invention adopts the following scheme:

[0007] A washable label automatic welding machine includes a frame and a control device, and the frame is also provided with:

[0008] The loading plate is provided with a welding station, multiple loading stations, a pushing station and multiple alignment stations. A loading device is provided above the loading station, a pushing device is provided above the pushing station, and an alignment device is provided below the alignment station. The loading plate is provided with alignment holes at the alignment station and the welding station for the alignment device to extend out.

[0009] The label storage device is arranged in front of the loading plate and includes a label storage box corresponding to the loading station one by one.

[0010] The loading device includes a loading rack, a loading drive device for driving the loading rack to move forward and backward, and several suction plates that can move up and down in the loading rack. The suction plates can move back and forth above the loading station and above the sign storage box through the loading drive device.

[0011] The pushing device includes a pushing piece for pushing the care label on the loading plate, a pushing motor for driving the pushing piece to move horizontally, and a pushing cylinder for driving the pushing piece to move up and down. The pushing piece can push the care label in the loading station into the alignment station and push the care label in the alignment station into the welding station.

[0012] The alignment device includes several stoppers that extend from alignment holes on the carrier plate and an alignment cylinder for driving the stoppers up and down. When the pusher pushes the care label into the alignment or welding station, the stoppers extend from the alignment holes, aligning the sides of the label with the stoppers. When the loading device places a new care label on the carrier plate, the pusher pushes the label on the carrier plate, and the alignment device extends from below the alignment hole, aligning the sides of all care labels on the carrier plate with the stoppers of the alignment device. This allows for quick and neat stacking of care labels before welding, improving production efficiency and product quality.

[0013] Ultrasonic welding device, the ultrasonic welding device is arranged above the welding station.

[0014] The operating principle of this automatic care label welding machine is as follows: A rack is equipped with a storage box for different care labels. For ease of understanding, the multiple storage boxes are labeled as storage box A, storage box B, storage box C, storage box D, storage box E, and storage box F. The suction trays include suction trays A, B, C, D, E, and F, which correspond to the storage boxes one by one. The loading stations include loading stations A, B, C, D, E, and F. During product operation, loading station A is empty, loading station B is loaded with label A, loading station C is loaded with labels A and B, loading station D is loaded with labels A, B, and C, loading station E is loaded with labels A, B, C, and D, and loading station F is loaded with labels A, B, C, D, and E. The loading device picks up six labels at a time, placing them into loading stations 1-F. The pushing device then simultaneously pushes the care label from loading station A into loading station B, the care label from loading station B into loading station C, and finally the care label from loading station F into the welding station, repeating this cycle, allowing multiple care labels to be loaded at once. As the pushing device pushes the care label into the next loading station, the alignment device's stopper extends from under the alignment hole. The pushing device continues pushing the care label forward until it hits the stopper, at which point the side of the care label engages with the alignment device's stopper, aligning them.

[0015] Furthermore, a welding groove corresponding to the ultrasonic welding device is provided at the upper end of the carrier plate, and a receiving cavity for installing a cover plate cylinder is provided at the lower end. A movable cover plate is provided above the welding groove, which is in contact with the upper surface of the carrier plate. A sliding groove is provided on the movable cover plate for the blocking sheet to pass through. The movable cover plate can be moved back and forth above the welding groove by the cover plate cylinder. When the pushing device pushes the washing label on the carrier plate toward the welding groove, the movable cover plate moves forward into the welding groove position under the action of the cover plate cylinder, and the alignment device rises at the same time, so that the washing label is smoothly pushed to the top of the welding groove and becomes neat under the action of the alignment device. Then, the movable cover plate exits the welding groove under the action of the cover plate cylinder. At this time, the alignment device can prevent the washing label from following the movement of the movable cover plate, so that it falls neatly into the welding groove. The movable cover plate solves the technical problem that the washing label cannot smoothly enter the welding groove when the pushing device moves it, thereby improving the welding effect and production efficiency of the washing label machine.

[0016] Furthermore, a right-angled trapezoidal mounting plate is installed below the loading plate, which is tilted onto the machine frame via the mounting plate. The loading plate also features several pusher slots that extend through the pusher station, and a pusher plate with pusher blocks corresponding to the pusher slots. This tilted loading plate automatically aligns the front and back ends of dropped care labels. The structural design of the pusher slots and pusher blocks prevents care labels from getting stuck on the loading plate, improving production efficiency.

[0017] Furthermore, the label storage box includes a first label storage box for placing large labels and a second label storage box for placing small labels, the suction tray includes a first suction tray corresponding to the first label storage box and a second suction tray corresponding to the second label storage box, and the second label storage box includes:

[0018] The bottom plate has a storage station for placing care labels.

[0019] The material blocking strips are arranged around the material storage station and are fixedly connected to the bottom plate.

[0020] The material blocking tooth plate includes a first material blocking tooth plate and a second material blocking tooth plate respectively arranged on both sides of the material storage station. The first material blocking tooth plate and the second material blocking tooth plate are both provided with tooth patterns for scratching the side of the water washing label on the side corresponding to the material storage station.

[0021] The tooth plate cylinder is arranged on the bottom plate and connected with the material blocking tooth plate. The tooth plate cylinder can drive the material blocking tooth plate to move on the bottom plate to tighten the washing label on the material storage station.

[0022] After the loading mechanism picks up the top layer of care labels from the second storage box, it moves back and forth several times in the second storage box, causing the teeth on the retaining plate to repeatedly scrape the sides of the care labels, thereby removing any labels stuck below the label. This effectively prevents the second suction tray from picking up multiple care labels at once, improving product quality.

[0023] Furthermore, the material-blocking tooth plate is a double-layer structure, and an L-shaped connecting block is provided on one side of the material-blocking tooth plate. One end of the connecting block is fixedly connected to the material-blocking tooth plate and the other end is fixedly connected to the slider. One end of the slider extends into the slide groove under the tooth plate cylinder and is connected to the tooth plate cylinder.

[0024] Furthermore, the pushing device also includes a pushing rack for fixing the pushing piece, a slider is provided at the lower end of the pushing rack, and a slide groove is provided at the lower end of the slider for connecting to the slide rail. One side of the pushing rack is fixedly connected to the gear belt provided on the pushing motor, and the pushing motor can drive the pushing rack to move back and forth on the slide rail through the gear belt.

[0025] Furthermore, the slide rail, the pushing motor and the gear belt are all fixed on the first lifting plate, the pushing cylinder is arranged below the first lifting plate and connected thereto, and the pushing cylinder can move the pushing piece up and down through the first lifting plate.

[0026] Furthermore, the blocking pieces are all arranged on the second lifting plate, and the alignment cylinder is arranged below the second lifting plate and connected thereto. The alignment cylinder can move the blocking pieces in the loading plate through the second lifting plate, and the alignment cylinders are respectively arranged at both ends below the second lifting plate.

[0027] Furthermore, the ultrasonic welding device includes an ultrasonic welding gun, a first welding cylinder for controlling the up and down movement of the ultrasonic welding gun, a second welding cylinder for controlling the left and right movement of the ultrasonic welding gun, and a blanking suction cup provided on one side of the ultrasonic welding gun and moving synchronously therewith.

[0028] Furthermore, a limiting fence for stacking the label boxes is installed on one side of the unloading suction cup. The limiting fence is fixedly connected to the frame, and a box-pushing cylinder is installed below the limiting fence. The box-pushing cylinder pushes the label boxes to the side of the loading plate. The unloading suction cup can use the second welding cylinder to deliver the wash labels in the welding station into the label box. The box-pushing cylinder can realize the automatic replacement of the label boxes, improving the automation level of the product.

[0029] Compared with existing technologies, the present invention offers the following advantages: This automatic care label welding machine automatically stacks, welds, and unloads labels, achieving highly automated production. The combination of a pusher and alignment device solves the problems of slow and uneven care label stacking, enabling quick and neat stacking of care labels. Furthermore, the loading device can load multiple care labels simultaneously, significantly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0039] like Figure 1-7 As shown, a washable label automatic welding machine includes a frame 2 and a control device 3. The frame 2 is also provided with:

[0040] Carrier plate 1, such as Figure 1-4 As shown, a welding station 101, multiple loading stations 102, a pushing station 103 and multiple alignment stations 104 are provided on the carrier plate 1. A loading device 4 is provided above the loading station 102, a pushing device 5 is provided above the pushing station 103, and an alignment device 6 is provided below the alignment station 104. The carrier plate 1 is provided with alignment holes 105 at the alignment station 104 and the welding station 101 for the alignment device 6 to extend out.

[0041] The tag storage device 7 is arranged in front of the loading plate 1, and the tag storage device 7 includes a tag storage box 701 corresponding to the loading station 102 one by one.

[0042] Feeding device 4, such as Figure 1 and 2 As shown, the loading device 4 includes a loading rack 401, a loading drive device 402 for driving the loading rack 401 to move forward and backward, and a plurality of suction plates 403 that can move up and down in the loading rack 401. The suction plates 403 can move back and forth above the loading station 102 and above the tag storage box 701 through the loading drive device 402.

[0043] Pushing device 5, such as Figure 1 and 3 As shown, the pushing device 5 includes a pushing piece 501 for pushing the care label on the loading plate 1, a pushing motor 502 for driving the pushing piece 501 to move horizontally, and a pushing cylinder 503 for driving the pushing piece 501 to move up and down. The pushing piece 501 can push the care label in the loading station 102 into the alignment station 104 and push the care label in the alignment station 104 into the welding station 101.

[0044] Alignment device 6, such as Figure 4As shown, the alignment device 6 includes several stoppers 601 that extend from the carrier plate 1 through the alignment holes 105, and an alignment cylinder 602 for driving the stoppers 601 up and down. When the pusher 5 pushes the care label into the alignment station 104 or welding station 101, the stoppers 601 extend from the alignment holes 105, aligning the sides of the care label with the stoppers 601. After the loading device 4 places a new care label on the carrier plate 1, the pusher 5 pushes the care label on the carrier plate 1, and the alignment device 6 extends from below the alignment holes 105, aligning the sides of all care labels on the carrier plate 1 with the stoppers 601 of the alignment device 6. This allows the care labels to be quickly and neatly stacked and loaded before welding, improving production efficiency and product quality.

[0045] The ultrasonic welding device 8 is arranged above the welding station 101 .

[0046] The operating principle of the automatic care label welding machine is as follows: a label storage box 701 for placing different care labels is provided on the frame 2. For ease of understanding, the multiple label storage boxes 701 are recorded as label storage box A 701, label storage box B 701, label storage box C 701, label storage box D 701, label storage box E 701, and label storage box F 701. The suction tray 403 includes an A suction tray 403, a B suction tray 403, a C suction tray 403, a D suction tray 403, a E suction tray 403, and a F suction tray 403 corresponding to the label storage boxes 701. The loading station 102 includes an A loading station 102, a B loading station 102, a C loading station 102, a D loading station 102, a E loading station 102, and a F loading station 102. During the product operation, there is no label at loading station A 102, label A at loading station B 102, labels A and B at loading station C 102, labels A, B and C at loading station D 102, labels A, B, C and D at loading station E 102, and labels A, B, C, D and E at loading station F 102; the loading device 4 absorbs 6 labels from 1 to F at a time and places them into loading stations 1 to F respectively, and then the pushing device 5 simultaneously pushes the washing label in loading station A 102 into loading station B 102, pushes the washing label in loading station B 102 into loading station C 102... and pushes the washing label in loading station F 102 into welding station 101, and repeats this cycle to achieve multiple washing labels at one time. When the pushing device 5 pushes the washing label into the next loading station 102, the blocking piece 601 of the alignment device 6 extends from under the alignment hole 105, and the pushing device 5 continues to push the washing label forward until the washing label hits the blocking piece 601. At this time, the side of the washing label is in contact with the blocking piece 601 of the alignment device 6 to align them.

[0047] Preferably, the upper end of the carrier plate 1 is provided with a welding groove 106 corresponding to the ultrasonic welding device 8, and the lower end is provided with a receiving cavity for installing a cover cylinder. The welding groove 106 is located at the welding station 101. Above the welding groove 106, a movable cover plate 107 is provided that is in contact with the upper surface of the carrier plate 1. The movable cover plate 107 is provided with a sliding groove 1071 for the blocking sheet 601 to pass through. The movable cover plate 107 can be moved back and forth above the welding groove 106 by the cover cylinder. When the pushing device 5 pushes the washing label on the carrier plate 1 to the welding groove 106, the movable cover plate 107 moves forward under the action of the cover cylinder and enters the welding groove 106 position. At the same time, the alignment device 6 rises, so that the washing label is smoothly pushed to the top of the welding groove 106 and becomes aligned under the action of the alignment device 6. Then, the movable cover plate 107 exits the welding groove 106 under the action of the cover cylinder. At this time, the alignment device 6 can prevent the washing label from following the movement of the movable cover plate 107, so that it falls neatly into the welding groove 106. The movable cover 107 solves the technical problem that the washing label cannot smoothly enter the welding groove 106 when the pushing device 5 moves the washing label, thereby improving the welding effect and production efficiency of the washing label machine.

[0048] Preferably, a right-angled trapezoidal fixing plate 108 is positioned below the carrier plate 1. The carrier plate 1 is tilted against the frame 2 of the care label machine via the fixing plate 108. The carrier plate 1 is also provided with several pusher slots extending through the pusher station 103, and the pusher piece 501 is equipped with several pusher blocks 508 corresponding to the pusher slots. The tilted carrier plate 1 automatically aligns the front and rear ends of dropped care labels. The structural design of the pusher slots and pusher blocks 508 prevents care labels from getting stuck on the carrier plate 1, improving production efficiency.

[0053] The tooth plate cylinder 7016 is arranged on the bottom plate 7013 and connected to the material blocking tooth plate 7015. The tooth plate cylinder 7016 can drive the material blocking tooth plate 7015 to move on the bottom plate 7013 to tighten the water washing label on the material storage station.

[0054] After the loading device 4 has sucked up the top layer of care labels from the second label storage box 7012, it then moves back and forth several times within the second label storage box 7012, causing the teeth on the retaining tooth plate 7015 to repeatedly scrape the sides of the care labels, thereby dropping any remaining care labels stuck below the sucked label. This effectively prevents the second suction tray 403 from sucking up multiple care labels at once, thereby improving the product quality rate.

[0059] Preferably, the ultrasonic welding device 8 includes an ultrasonic welding gun 801, a first welding cylinder 802 for controlling the up and down movement of the ultrasonic welding gun 801, a second welding cylinder 803 for controlling the left and right movement of the ultrasonic welding gun 801, and a blanking suction cup 9 provided on one side of the ultrasonic welding gun 801 and moving synchronously therewith.

[0060] Preferably, a limiting fence 10 for stacking the label boxes 11 is further provided on one side of the unloading suction cup 9. The limiting fence 10 is fixedly connected to the frame 2.
