Description

TECHNICAL FIELD

[0001] The utility model relates to cap processing field technology especially is a kind of cap piece automatic embroider eye machine. BACKGROUND

[0002] As shown in Figures 15 to 18 For example, baseball cap is made by a plurality of cap pieces, which are generally cut by automatic cutting, and the adjacent cloth is folded into multiple layers, and then cut by a cutter, so that the stack of cap pieces is alternately stacked with a front face and a back face. At least two cap pieces on the baseball cap are provided with hat eyes, so the stack of cap pieces needs to be embroidered with eyes.

[0003] In the prior art, the cap pieces are generally loaded one by one under the embroider eye machine, and the embroider eye machine automatically embroiders the cap pieces, and then the cap pieces are unloaded one by one. The cap pieces after embroidering are stacked together, and different numbers of cap pieces with hat eyes and cap pieces without hat eyes are selected according to the type of baseball cap (generally 6 pieces), and then the cap pieces are sewn to form a baseball cap body. The prior art has many shortcomings:

[0004] 1. When the cap pieces are loaded under the embroider eye machine for embroidering, the front and back faces of the cap pieces are not distinguished, which can easily cause the embroidering effect of the front and back faces of the cap pieces to be inconsistent. However, in practice, the front face of the cap piece faces outward when the baseball cap is used. For high-quality hat orders, it is difficult to ensure the yield.

[0005] 2. If a large piece of cloth (or multiple large pieces of cloth) is cut to obtain a plurality of cap pieces, and the cap pieces are sewn to form a baseball cap body, color difference can easily occur between the two cap pieces with hat eyes. For high-quality hat orders, this further leads to poor quality of the finished hat.

[0006] 3. Although automatic embroider eye machines and automatic sewing machines are used in the industry for cap piece processing, there is still a lot of manual involvement in the process, which limits the automation level of hat processing and is not conducive to ensuring the consistency of processing efficiency and processing quality.

The translation seat is connected to the material moving left-right translation driving unit 85 and is driven by the material moving left-right translation driving unit 85 to translate left and right.

[0094] The laminating station 16 comprises a first correction station 161 and a second correction station 162 arranged side by side. The second automatic turnover mechanism 60 turns the cap piece after eyeletting from the transfer station 15 to the first correction station 161, i.e. turns the cap piece with the front face upward to the back face upward. The first correction station 161 and the second correction station 162 are both provided with a lower guide groove D1 extending left and right. A correction piece J1 is arranged in the lower guide groove D1. The correction piece J1 is connected to a correction driving unit. The correction driving unit drives the correction piece J1 to move left and right in the lower guide groove D1 to correct the left and right sides of the cap piece.

[0095] A pressing mechanism is arranged corresponding to the lamination station 16, which comprises a first pressing mechanism Y1 and a second pressing mechanism Y2 arranged side by side. The first pressing mechanism Y1 comprises a first pressing plate Y11 and a first pressing lifting driving unit Y12 connected to the first pressing plate Y11 to drive the first pressing plate Y11 to act up and down. The second pressing mechanism Y2 comprises a second pressing plate Y21 and a second pressing lifting driving unit Y22 connected to the second pressing plate Y21 to drive the second pressing plate Y21 to act up and down. The first pressing plate Y11 and the second pressing plate Y21 are both provided with an upper guide groove D2 extending left and right, which is arranged vertically corresponding to the lower guide groove D1, so that the correction sheet J1 passes through the lower guide groove D1 and the corresponding upper guide groove D2. The bottom of the second pressing plate Y21 is a vacuum adsorption surface. The second pressing mechanism Y2 is connected with a lamination translation driving unit, which drives the second pressing mechanism Y2 to suck and stack the cap sheet from the first correction station 161 to the cap sheet of the second correction station 162. In actual design, the lamination translation driving unit can be driven and connected to the first pressing mechanism Y1 and the second pressing mechanism Y2, that is, when the second pressing mechanism Y2 translates and laminates, the first pressing mechanism Y1 also translates.

[0096] In addition, a rotating receiving table X1 is arranged below the discharging station 18, and a group of cap sheets fall from the discharging station 18 to the rotating receiving table X1 and are arranged in a circumferential direction. Here, an automatic discharging mechanism is arranged in the discharging station 18, which comprises a blocking bottom plate X2, a top pressing assembly X3 and a discharging translation driving unit X4. The top pressing assembly X3 is located above the blocking bottom plate X2. When a group of cap sheets are sent to the discharging station 18, the cap sheets are located on the blocking bottom plate X2, and the top pressing assembly X3 can act downward to press on the top of the cap sheets. When the discharging translation driving unit X4 works, it drives the blocking bottom plate X2 and the top pressing assembly X3 to translate leftward. Since the top surface of the blocking bottom plate X2 is relatively smooth, and the top pressing assembly X3 (which adopts a cylinder to drive a top pressing plate. Before the cap sheets reach the discharging station 18, the top pressing plate rises to avoid the cap sheets. After the cap sheets are in place, the top pressing plate descends to press on the top of the cap sheets) can provide a certain friction force to the top of the cap sheets, the front end of the group of cap sheets is deflected to the right and falls onto the rotating receiving table X1.

[0097] Next, the working process of the cap sheet automatic eye embroidering and sewing integrated machine of the second embodiment is introduced:

[0098] The stacked cap pieces are placed in the hopper 21, and the first piece is set in reverse. The first piece is picked up by the feeding manipulator 22 (pin suction cup) and then moved to the first feeding station 11. The cap piece is positioned by suction and a positioning pin can be further set to penetrate the cap piece to enhance the positioning. Then, the first cap piece is flipped by the first automatic flipping mechanism 30 to the second feeding station 12. At this time, the first cap piece is changed from reverse to front. The second cap piece is moved to the first feeding station 11. Then, the second cap piece and the first cap piece are moved to the two embroidery devices (the first embroidery station 13 and the second embroidery station 14) by the first feeding manipulator 81 and the second feeding manipulator 82. After the embroidery is completed, the embroidered cap pieces on the first embroidery station 13 and the second embroidery station 14 are moved to the transfer station 15 and the second correction station 162 of the stacking station 16 by the third feeding manipulator 83 and the fourth feeding manipulator 84. The embroidered cap piece on the transfer station 15 is flipped by the second automatic flipping mechanism 60 to the first correction station 161 of the stacking station 16. The first pressing mechanism Y1 and the second pressing mechanism Y2 are respectively pressed on the second cap piece and the first cap piece. The left and right correction pieces J1 are moved to the middle to correct the horizontal position of the cap piece. After the two cap pieces are respectively corrected in the first correction station 161 and the second correction station 162, the second cap piece on the first correction station 161 is stacked on the first cap piece (front up) on the second correction station 162 by the second pressing mechanism Y2. The front of the two cap pieces is stacked in opposite directions. Then, the stacked cap pieces (i.e., a group of two cap pieces) on the second correction station 162 of the stacking station 16 are moved to the sewing station 17 by the moving and pressing frame assembly. The two cap pieces are sewn together (i.e., one side of the two cap pieces is sewn) by the sewing device 90 on the sewing station 17. Then, the group of cap pieces after sewing is moved to the left to the discharging station 18 by the moving and pressing frame assembly, and then discharged to the rotating receiving table X1 by the automatic discharging mechanism.

The second automatic feeding mechanism 20' and the first automatic feeding mechanism 20 are arranged side by side (e.g., symmetrically arranged). The two have the same or basically the same structure and are each equipped with a material bin to feed the cap pieces from their respective bins to the first feeding station 11 and the second feeding station 12, respectively. In cases where flipping is not required, such as when the cap pieces in both bins are facing upwards, the first automatic feeding mechanism 20 and the second automatic feeding mechanism 20' simultaneously feed the cap pieces from their respective bins to the first feeding station 11 and the second feeding station 12, without needing to flip the cap pieces from the first feeding station 11 to the second feeding station 12, thus further improving feeding efficiency. Of course, this automatic embroidery machine for cap pieces can also use only the first automatic feeding mechanism 20 and the hopper. For example, if only the first automatic feeding mechanism 20 and the hopper on the right are used, it is equivalent to the second automatic feeding mechanism 20' and the hopper on the left being disabled. Its usage and operation process can be the same as in Example 1.

The main difference is that Embodiment 4 is equipped with two sets of automatic feeding mechanisms, namely: a first automatic feeding mechanism 20 and a second automatic feeding mechanism 20'. The second automatic feeding mechanism 20' and the first automatic feeding mechanism 20 are arranged side by side (e.g., symmetrically arranged). The two have the same or basically the same structure and are each equipped with a material bin to feed the cap pieces from their respective material bins to the first feeding station 11 and the second feeding station 12, respectively. In cases where flipping is not required, such as when the cap pieces in both material bins are facing upwards, the first automatic feeding mechanism 20 and the second automatic feeding mechanism 20' simultaneously feed the cap pieces from their respective material bins to the first feeding station 11 and the second feeding station 12, without needing to flip the cap pieces from the first feeding station 11 to the second feeding station 12, thus further improving the feeding efficiency. Of course, this automatic embroidery machine for cap pieces can also use only the first automatic feeding mechanism 20 and the hopper. For example, if only the first automatic feeding mechanism 20 and the hopper on the right are used, it is equivalent to the second automatic feeding mechanism 20' and the hopper on the left being disabled. Its usage and operation process can be the same as in Embodiment 2.
