Description

Technical Field

[0001] This utility model relates to the field of sewing technology, and in particular to a positioning mechanism for a double-leaf flap, which is mainly but not limited to the positioning of the two flaps when the support material is opened. Background Technology

[0002] Reference Figure 6 and Figure 7 As shown, taking a baseball cap as an example, its crown is formed by sewing together several adjacent cap pieces A1 to create a hemispherical crown. In actual sewing, two adjacent cap pieces A1 are overlapped and sewn on one side. Then, the two cap pieces A1 are turned outwards from the center seam A2 as a reference. The presser foot needs to be placed on top of the two cap pieces A1 after they are turned out, and double needle sewing is performed on both sides of the center seam A2. During sewing, a side strip A3 is placed on the inside of the cap piece A1. The side strip covers the center seam A2 of the two cap pieces A1. The two sides of the side strip A3 form a sewing track A4 with the corresponding positions of the two cap pieces A1's center seam A2.

[0003] CN113235233A discloses a page-turning component in an automated cap-making production line, including a mounting base, a page-turning assembly, two sets of drive assemblies, a translation assembly, and an angle adjustment assembly. The page-turning assembly is correspondingly mounted on the top of the mounting base. The two sets of drive assemblies are matched and mounted on the side walls of the mounting base, and the output end of the drive assemblies is pulsatorically connected to the page-turning assembly. The angle adjustment assembly is mounted on the lower surface of the mounting base, and the translation assembly is matched and mounted on the lower surface of the angle adjustment assembly. In use, after the fabric is conveyed, it falls onto the left and right side plates. The left and right side plates are used to collect the fabric, and the operator uses an electrically controlled cylinder, driven by a connecting component, to clamp and open the left and right side plates.

[0004] However, this structure has some limitations and shortcomings: the left and right side plates do not clamp the fabric tightly enough when in the clamping state, which makes it difficult for the left and right suction cups to stably hold the fabric, thus affecting the unfolding effect of the fabric.

[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a positioning mechanism for a double-leaf flip plate. It utilizes a horizontal positioning mechanism to ensure that the plate is in a horizontal and stable state, preventing it from tilting and collapsing downwards during material feeding. It also utilizes a vertical positioning mechanism to make the left and right side plates adhere more tightly to the material sheet, thereby improving the positioning firmness of the left and right side plates on the attached material sheet and enabling the material sheet to be flipped open accurately following the left and right side plates.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A positioning mechanism for a double-page flip panel includes a left side panel and a right side panel, which can automatically flip up and down around an axis; a horizontal positioning mechanism and a vertical positioning mechanism are provided below the left side panel and the right side panel.

[0009] The horizontal positioning mechanism includes a lifting drive unit and a support member, wherein the lifting drive unit drives the support member to move up and down.

[0010] The vertical positioning mechanism includes a flipping drive unit and two sets of clamps, and the flipping drive unit drives the two sets of clamps to flip up and down.

[0011] In the first state, the left side plate and the right side plate are flipped upward and brought together to a vertical position. The flipping drive unit drives the two sets of clamps to flip upward and bring together to further clamp the left side plate and the right side plate.

[0012] In the second state, the left side plate and the right side plate are flipped downwards and moved away to a horizontal state, and the lifting drive unit drives the support member to rise to support the bottom of the left side plate and the right side plate respectively.

[0013] As a preferred embodiment, the lifting drive unit is a lifting cylinder, the telescopic end of the lifting cylinder is connected to a lifting plate, and at least two support members are provided, with their lower ends respectively on the lifting plate. At least one support member is used to support the left side plate, and at least the other support member is used to support the right side plate.

[0014] As a preferred embodiment, the flipping drive unit is a flipping clamping cylinder, with two sets of clamps respectively connected to the two rotating ends of the flipping clamping cylinder; the clamps are horizontally extended, with a clamping protrusion extending upward from the top of their outer ends, and the inner ends of the clamps are respectively connected to the left and right sides of the flipping clamping cylinder. When the flipping clamping cylinder drives the two rotating ends to flip upward and close together, the clamps are in a vertical state, and the clamping protrusions are horizontally pressed inward against the left side plate and the right side plate.

[0015] As a preferred embodiment, the flipping drive unit is located directly below the shaft, with its two rotating ends symmetrically positioned on the left and right sides of the downward projection area of ​​the shaft.

[0016] As a preferred embodiment, both the left side plate and the right side plate are provided with vacuum adsorption units for holding the sheet; or, both the left side plate and the right side plate are provided with puncture positioning units for piercing the sheet.

[0017] After the flipping drive unit drives the two sets of clamps to clamp the left side plate and the right side plate, the vacuum adsorption unit or the puncture positioning unit starts to work.

[0018] As a preferred embodiment, a workpiece sensing unit is provided below the right side plate, and correspondingly, a sensing hole is provided on the right side plate. When the workpiece sensing unit senses that the workpiece has been placed on the right side plate, the right side plate automatically flips upward.

[0019] As a preferred embodiment, the left and right side plates are automatically flipped up and down around an axis by a motor.

[0020] As a preferred embodiment, the left side plate is driven to rotate up and down by a first motor; the first motor is connected to a first drive wheel, a first transmission wheel, and a first synchronous belt; the first drive wheel is connected to the first motor, the first transmission wheel is rotatably sleeved on the shaft and connected to the left side plate, and the first synchronous belt is connected between the first drive wheel and the first transmission wheel;

[0021] The right side plate is driven to rotate up and down by a second motor; the second motor is connected to a second drive wheel, a second transmission wheel and a second synchronous belt; the second drive wheel is connected to the second motor, the second transmission wheel is rotatably sleeved on the shaft and connected to the right side plate, and the second synchronous belt is connected between the second drive wheel and the second transmission wheel.

[0022] As a preferred embodiment, the left and right side plates are automatically flipped up and down around an axis by a cylinder.

[0023] As a preferred embodiment, the clamp is configured to correspond to either the vacuum adsorption unit or the puncture positioning unit.

[0024] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves setting a horizontal positioning mechanism and a vertical positioning mechanism below the left and right side plates. The horizontal positioning mechanism ensures that the plates are in a horizontal and stable state, preventing them from tilting and collapsing downwards when the material is released, while providing a precise horizontal position to facilitate controllability when flipping to other positions. The vertical positioning mechanism makes the left and right side plates adhere more tightly to the material sheet. Thus, after further clamping, the vacuum adsorption unit is controlled to hold the sheet (or the piercing positioning unit is controlled to pierce the sheet), improving the positioning firmness of the left and right side plates on the attached material sheet, so that the material sheet can be accurately flipped open according to the left and right side plates.

[0033] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation 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.

[0035] A positioning mechanism for a double-leaf flip plate includes a left side plate 401 and a right side plate 402. The left side plate 401 and the right side plate 402 can automatically flip up and down around an axis 403. The left side plate 401 and the right side plate 402 can be driven by a cylinder or a motor to automatically flip up and down. Each of the left side plate 401 and the right side plate 402 is provided with a vacuum adsorption unit 411 for adsorbing the sheet material; or, each of the left side plate 401 and the right side plate 402 is provided with a piercing positioning unit for piercing the sheet material. A horizontal positioning mechanism and a vertical positioning mechanism are provided below the left side plate 401 and the right side plate 402.

[0036] The horizontal positioning mechanism includes a lifting drive unit 45 and a support member 46. The lifting drive unit 45 drives the support member 46 to move up and down. In this embodiment, the lifting drive unit 45 is a lifting cylinder. The telescopic end of the lifting cylinder is connected to a lifting plate 451. At least two support members 46 are provided, with their lower ends on the lifting plate 451. At least one support member 46 is used to support the left side plate 401, and at least another support member 46 is used to support the right side plate 402.

[0037] The vertical positioning mechanism includes a flipping drive unit 47 and two sets of clamps 48. The flipping drive unit 47 drives the two sets of clamps 48 to flip up and down. In this embodiment, the flipping drive unit 47 is a flipping clamping cylinder, which is also commonly referred to as a rotary clamping cylinder. The two sets of clamps 48 are respectively connected to the two rotating ends of the flipping clamping cylinder. The clamps 48 extend horizontally, with a clamping protrusion 481 extending upward from the top of their outer ends. The inner ends of the clamps 48 are respectively connected to the flipping cylinder. When the rotating clamping cylinder drives the two rotating ends to rotate 90 degrees upwards and closer together, the chuck 48 is in a vertical position, and the clamping protrusion 481 is horizontally inwards against the left side plate 401 and the right side plate 402 (referring to the left side surface of the left side plate 401 and the right side surface of the right side plate 402). When the rotating clamping cylinder drives the two rotating ends to rotate 90 degrees downwards and away from each other, the chuck 48 is in a horizontal position, and the clamping protrusion 481 is vertically upwards. The rotating drive unit 47 is located directly below the shaft 403, with the two rotating ends symmetrically located on the left and right sides of the downward projection area of ​​the shaft 403.

[0038] In the first state, the left side plate 401 and the right side plate 402 are flipped upward and brought together in a vertical state. The flipping drive unit 47 drives the two sets of clamps 48 to flip upward and bring together to further clamp the left side plate 401 and the right side plate 402, so that the left side plate 401 and the right side plate 402 are more closely attached to the material sheet.

[0039] In the second state, the left side plate 401 and the right side plate 402 are flipped downwards and moved away to a horizontal position. The lifting drive unit 45 drives the support member 46 to rise and support the bottom of the left side plate 401 and the right side plate 402 respectively, ensuring that they are in a horizontal and stable state and preventing them from tilting and collapsing downwards during material placement. Preferably, a workpiece sensing unit is provided below the right side plate 402, and correspondingly, a sensing hole is provided on the right side plate 402. When the workpiece sensing unit senses that the workpiece has been placed on the right side plate 402, the right side plate automatically flips upwards.

[0040] Preferably, after the flipping drive unit 47 drives the two sets of clamps 48 to clamp the left side plate 401 and the right side plate 402, the vacuum adsorption unit 411 or the puncture positioning unit starts working. The clamps 48 are set to correspond to the vacuum adsorption unit 411 or the puncture positioning unit for better clamping effect.

[0041] In this embodiment, the left side plate 401 and the right side plate 402 are automatically rotated up and down around an axis 403 by a motor. The left side plate is driven to rotate up and down by a first motor; the first motor is connected to a first drive wheel, a first transmission wheel, and a first synchronous belt; the first drive wheel is connected to the first motor, the first transmission wheel is rotatably sleeved on the axis and connected to the left side plate, and the first synchronous belt is connected between the first drive wheel and the first transmission wheel; the right side plate is driven to rotate up and down by a second motor; the second motor is connected to a second drive wheel, a second transmission wheel, and a second synchronous belt; the second drive wheel is connected to the second motor, the second transmission wheel is rotatably sleeved on the axis and connected to the right side plate, and the second synchronous belt is connected between the second drive wheel and the second transmission wheel. Of course, in other embodiments, a cylinder can also be used to drive the left side plate 401 and the right side plate 402 to automatically rotate up and down around an axis 403.

[0042] The key design feature of this invention lies in the presence of a horizontal positioning mechanism and a vertical positioning mechanism located below the left and right side plates. The horizontal positioning mechanism ensures the material is in a stable horizontal position, preventing it from tilting or collapsing during material feeding and providing a precise horizontal position for controllable flipping to other positions. The vertical positioning mechanism allows the left and right side plates 401 and 402 to adhere more tightly to the material sheet. This further clamping, followed by the control of the vacuum adsorption unit to hold the sheet in place (or the control of the piercing positioning unit to pierce the sheet), enhances the positioning firmness of the left and right side plates on the attached material sheet, enabling the material sheet to be accurately flipped open following the left and right side plates.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
