Description

Technical Field

[0001] The invention relates to the technical field of clothing production equipment, and in particular to a cutting piece positioning, clamping and fixing device. Background Art

[0002] As the degree of automation in garment factories increases, the garment-making process is gradually replaced by automatic sewing equipment instead of manual work. In the production process of knitted garments, there is a ribbing foot process. Ribbing foot refers to laying the ribbed pieces and the body pieces on the ribbing sewing machine as required, and then sewing the two pieces together using the ribbing sewing machine. Usually, two tensioning wheels are set on the automatic sewing equipment to tension the pieces and drive the pieces to rotate, so that the sewing device can sew.

[0003] In order to ensure the quality of sewing, precise positioning is required when laying out the pieces. When laying out the ribbed pieces and the body pieces, theoretically, they only need to be laid out twice, but it is often easy for the laid pieces to shift when the second piece is laid out. For example, if the ribbed pieces are laid out on the ribbed sewing machine first, when laying out the body pieces, the body pieces and the ribbed pieces come into contact, causing the ribbed pieces to shift. This results in the need to lay out and position the pieces multiple times when laying out the ribbed pieces and the body pieces, greatly reducing production efficiency and affecting positioning accuracy. Summary of the invention

[0004] Based on this, it is necessary to provide a cutting piece positioning, clamping and fixing device, aiming to solve the problem of inconvenient positioning when laying cutting pieces in the prior art.

[0008] In the above scheme, by setting a mobile platform that can move between a first position and a second position, the positioning mechanism can fix the cut pieces, so that when laying the cut pieces, the first cut piece can be fixed by the positioning mechanism after it is laid, so as to avoid the first cut piece from shifting when the second cut piece is laid, thereby improving production efficiency. At the same time, the above scheme also sets a deviation correction mechanism on the mobile platform, and the deviation correction mechanism drives the cut piece to move by using its own movement and the friction between the correcting mechanism and the cut piece, so that after the cut piece is laid, the position of the cut piece can be adjusted, and it is not necessary to lay it again, thereby improving production efficiency.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0028] When laying the cut pieces on the automatic sewing equipment, in order to realize the automatic sewing of the automatic sewing equipment, it is necessary to wrap the two cut pieces around the two tensioning wheels and form a closed loop, with one cut piece between the other cut piece and the tensioning wheel, and the two tensioning wheels can drive the two cut pieces to rotate around the two tensioning wheels together, so that the two cut pieces are connected as a whole after sewing. The cut piece tensioning direction refers to the direction in which the cut piece is tensioned between the two tensioning wheels and moves, that is, the cut piece tensioning direction is consistent with the direction of the connecting line of the wheel centers of the two tensioning wheels.

[0029] like Figure 1 and Figure 2As shown, the present application proposes a cutting piece positioning, clamping and fixing device 100, comprising: a positioning mechanism 110 and a deviation correction mechanism 120. The positioning mechanism 110 comprises a moving platform 111 that can move between a first position and a second position. When the moving platform 111 is located at the second position, the positioning mechanism 110 can fix the cutting piece in a direction perpendicular to the plane of the cutting piece. The deviation correction mechanism 120 can contact the cutting piece and is used to drive the cutting piece to move in a direction perpendicular to the tensioning direction of the cutting piece.

[0030] It can be understood that the movable table 111 moves between the first position and the second position, and the movable table 111 moves from the first position to the second position to complete the fixing of the cut piece. Since the movable table 111 can fix the cut piece when it is in the second position, the movable table 111 at least in the second position can apply pressure to the cut piece in a direction perpendicular to the plane of the cut piece.

[0031] It should be noted that the relative positions of the first position and the second position are not unique: for example, the first position and the second position are arranged in a direction perpendicular to the plane of the cutting piece, wherein the first position can be directly below or directly above the second position, and in this case, the positioning mechanism 110 moves from the first position to the second position in a direction perpendicular to the plane of the cutting piece; or, the first position can also be located in any direction of the second position, and in this case, the movement route of the positioning mechanism 110 from the first position to the second position can be a zigzag line or an arc line.

[0032] It can be understood that when the first position and the second position are arranged in a direction perpendicular to the plane of the cut piece, the route between the first position and the second position is shorter, and the movable table 111 is set to the second position in which a pressure perpendicular to the plane of the cut piece can be applied to the cut piece along a straight line. At this time, the movable table 111 moves from the first position to the second position faster, the operation process is more convenient, and the equipment structure is simpler. In this embodiment, the first position and the second position are arranged in a direction perpendicular to the plane of the cut piece.

[0033] Under the above premise, if Figure 1 As shown, for the sake of ease of description, the plane of the cutting piece is set as the XY plane in this application, where the X-axis direction is parallel to the direction of the connecting line of the two tensioning wheels, and the correction mechanism 120 drives the cutting piece to move in the direction perpendicular to the X-axis direction, then the Y-axis direction is parallel to the movement direction of the correction mechanism 120, then the movement direction of the positioning mechanism 110 is perpendicular to the cutting piece plane, and the Z-axis direction is parallel to the movement direction of the positioning mechanism 110. It can be understood that the XYZ three axes form a spatial rectangular coordinate system, in which the X-axis, Y-axis, and Z-axis are perpendicular to each other. That is, the first direction described in this application is Figure 1 The middle direction is the Z axis, the second direction is the Y axis, and the cutting piece tensioning direction is the X axis.

[0034] It should be noted that the X-axis, Y-axis and Z-axis set above can be understood as representing only the horizontal axis, the vertical axis and the vertical axis respectively, indicating that the three are perpendicular to each other, but are not limited in direction. In other words, the cut piece is tensioned along the horizontal axis, the correction mechanism 120 drives the cut piece to move along the vertical axis, and the positioning mechanism 110 moves along the vertical axis to move from the first position to the second position.

[0035] Furthermore, the deflection correction mechanism 120 is connected to the moving platform 111, and the deflection correction mechanism 120 can adjust whether it is in contact with the cut piece as the moving platform 111 moves on the Z axis. Under the premise of not damaging the cut piece, the deflection correction mechanism 120 contacts the cut piece and generates friction, so that the deflection correction mechanism 120 drives the cut piece to move synchronously through its own movement.

[0036] It is understandable that when the friction between the correcting mechanism 120 and the cut piece is too small, the movement of the correcting mechanism 120 cannot drive the cut piece. At this time, the position of the correcting mechanism 120 can be adjusted by the movable platform 111 to generate pressure between the correcting mechanism 120 and the cut piece, thereby increasing the friction between the correcting mechanism 120 and the cut piece, and then realizing the movement of the correcting mechanism 120 to drive the cut piece.

[0037] It should be noted that the deviation correction mechanism 120 is not only used to correct the position of the cut piece during the laying process, but can also be used to correct the position of the cut piece during the sewing process. During the sewing process, the cut piece rotates around the two tensioning wheels under the action of the tensioning wheels. At this time, the deviation correction mechanism 120 can be used to correct the position of the cut piece during the sewing state to prevent the cut piece from tilting during the sewing process, resulting in poor sewing quality, thereby ensuring the sewing quality.

[0038] Generally, the positioning mechanism 110 is used to fix the first piece of cut pieces during the laying process of the cut pieces or to jointly position two pieces of cut pieces before sewing.

[0039] Therefore, although the deflection-correcting mechanism 120 is connected to the positioning mechanism 110 and relies on the positioning mechanism 110 to move in the Z-axis direction, it is not limited to being able to contact the cut piece only when the positioning mechanism 110 is in the second position. Specifically, when the deflection-correcting mechanism 120 is applied to the process of laying the cut piece, the moving platform 111 is in the second position, and the cut piece is in a state of being fixed by the positioning mechanism 110. At this time, the deflection-correcting mechanism 120 can contact the cut piece, and the movement of the deflection-correcting mechanism 120 can be used to drive the cut piece to move in the Y-axis. When the deflection-correcting mechanism 120 is applied to the process of sewing the cut piece, the positioning mechanism 110 only needs to drive the deflection-correcting mechanism 120 to move to the position in contact with the cut piece, and is not limited to being in the first position or the second position, but the position in contact with the cut piece by the deflection-correcting mechanism 120 should be between the first position and the second position.

[0040] In one of the embodiments, since the cutting piece is fixed by the positioning mechanism 110, the power of the correction mechanism 120 to drive the cutting piece to move needs to overcome the fixation of the cutting piece by the positioning mechanism 110, and the required power is relatively large. Therefore, the distance between the correction mechanism 120 and the cutting piece can be smaller than the distance between the positioning mechanism 110 and the cutting piece. At this time, the correction mechanism 120 can move the cutting piece for correction when it is turned on, and when the correction mechanism 120 is turned off, the correction mechanism 120 in contact with the cutting piece is driven by the positioning mechanism 110 to fix the cutting piece.

[0041] In the above scheme, by setting a movable platform 111 that can move between a first position and a second position, the positioning mechanism 110 can fix the cut pieces, so that when laying the cut pieces, the first cut piece can be fixed by the positioning mechanism 110 after it is laid, so as to avoid the first cut piece from shifting when the second cut piece is laid, thereby improving production efficiency. At the same time, the above scheme also sets a deviation correction mechanism 120 on the movable platform 111, and the deviation correction mechanism 120 drives the cut piece to move by its own movement and the friction between the cut piece and the cut piece, so that the position of the cut piece can be adjusted after the cut piece is laid, and it is not necessary to lay it again, thereby improving production efficiency.

[0042] Please participate Figure 1 and Figure 2 Furthermore, the positioning mechanism 110 further includes a telescopic mechanism 112, and the telescopic mechanism 112 drives the mobile platform 111 to move between the first position and the second position. It can be understood that the telescopic mechanism 112 can drive the mobile platform 111 to move from the first position to the second position, and can also move the mobile platform 111 from the second position to the first position.

[0043] It is understandable that the telescopic mechanism 112 includes at least a telescopic rod and a driving source, and the driving source can drive the telescopic mechanism 112 to extend or shorten along the Z-axis direction to drive the moving platform 111 to move between the first position and the second position. The driving source can be a cylinder or a hydraulic cylinder.

[0044] It is obvious that the moving platform 111 is connected to the telescopic mechanism 112, which can be fixedly connected, detachably connected or integrally formed. Specifically, the moving platform 111 and the telescopic mechanism 112 can be connected by threaded connection, welding or the like.

[0045] See also Figure 2 It should be noted that when the moving platform 111 is in the second position, the moving platform 111 is in contact with the cut piece, and there is an interaction force between the moving platform 111 and the cut piece that is perpendicular to the plane of the cut piece. In this embodiment, there is an interaction force in the Z-axis direction between the moving platform 111 and the cut piece; when the moving platform 111 is in the first position, the moving platform 111 is not in contact with the cut piece, and the cut piece can move freely.

[0046] See also Figure 1 and Figure 2 Furthermore, the positioning mechanism 110 also includes a support platform 113, which is fixed in position and is used to cooperate with the moving platform 111 to fix the cut piece. When the moving platform 111 is located at the second position, the moving platform 111 clamps the cut piece between the moving platform 111 and the support platform 113.

[0047] It can be understood that the fixed position of the support platform 113 refers to the fixed position of the support platform 113 relative to the automatic sewing equipment. The support platform 113 can be fixed to the automatic sewing equipment, and its fixing method can be one of threaded connection, welding, etc.

[0048] It is obvious that the main function of the support platform 113 is to cooperate with the moving platform 111 to fix the position of the cut piece, so the material and shape of the support platform 113 are not limited. In this embodiment, the support platform 113 is an iron sheet, which is threadedly connected to the automatic sewing equipment.

[0049] It is understandable that the position of the support platform 113 should be fixed in the moving direction of the mobile platform 111 so that the cut piece is located between the support platform 113 and the mobile platform 111. When the mobile platform 111 is located at the second position, the cut piece is clamped between the support platform 113 and the mobile platform 111, and interaction forces are generated between the cut piece and the support platform 113 and the mobile platform 111, so that the friction between the cut piece and the support platform 113 and the mobile platform 111 increases. When laying the cut pieces, it is ensured that the first cut piece cannot move when affected by the second cut piece, thereby achieving the fixed position of the cut piece.

[0050] See also Figure 1 Furthermore, the correcting mechanism 120 includes: a correcting member, which is connected to the moving platform 111, and can move relative to the cut piece in a direction perpendicular to the tensioning direction of the cut piece, and contact the cut piece to drive the cut piece to move; a correcting drive 122, which is used to drive the correcting member to move.

[0051] It can be understood that the correcting member is connected to the movable table 111 so that the correcting member can move with the movement of the movable table 111 in the Z-axis direction, but the correcting member and the movable table 111 are movably connected so that the correcting member can move relative to the movable table 111 in the Y-axis direction.

[0052] It is understood that the deflection-correcting member can move relative to the cut piece in a direction perpendicular to the cut piece tensioning direction, which means that the deflection-correcting member can move in the Y-axis direction. The deflection-correcting member contacts the cut piece and generates friction between the two, and the friction is used to drive the cut piece to move along the moving direction of the deflection-correcting member.

[0053] The correcting drive 122 serves as the power source of the correcting element. In order to reduce power loss in the power process, the correcting drive 122 can also be connected to the moving platform 111 to reduce the distance between the correcting drive 122 and the correcting element, so that the power of the correcting drive 122 can be used as much as possible to move the correcting element.

[0054] See also Figure 1 The deviation correction drive 122 includes a driving machine 1211 , a driving wheel 1222 and a driven wheel 1223 , wherein the driving wheel 1222 is connected to the output shaft of the driving machine 1211 .

[0055] It can be understood that the driving machine 1221 can be a power source such as a motor, a heat engine, etc. In this embodiment, the driving machine 1221 is a motor.

[0056] It is understandable that the driving wheel 1222 can be directly connected to the output shaft of the driving machine 1211, or can be indirectly connected to the output shaft of the driving machine 1211 through a gear structure, etc. In this embodiment, the driving wheel 1222 is directly connected to the output shaft of the deviation correction motor.

[0057] It should be noted that the output shaft of the deflection correction motor can be adjusted to rotate in a direction by adjusting the setting of the deflection correction motor. For example, when the output shaft of the deflection correction motor rotates clockwise, the driving wheel 1222 also rotates clockwise, the conveyor belt 121 and the driving wheel 1222 rotate in the same direction, and drive the cut piece to move along the direction of rotation of the conveyor belt 121. If the cut piece moves too far in this direction, the rotation direction of the output shaft of the deflection correction motor can be changed to counterclockwise rotation, and the driving wheel 1222 also rotates clockwise, and the transmission belt and the driving wheel 1222 rotate in the same direction. At this time, the moving direction of the carrier is opposite to the original moving direction to adjust the deviation.

[0058] It is understandable that when the deviation correction motor and the driving wheel 1222 are indirectly connected, the driving wheel 1222 and the output shaft of the deviation correction motor may also rotate in opposite directions, which will not be exemplified here.

[0059] See also Figure 1 Furthermore, the deviation-correcting member is a conveyor belt 121 , which is connected between the driven wheel 1223 and the driving wheel 1222 and is in a closed loop. The driving wheel 1222 drives the conveyor belt 121 to rotate around the driven wheel 1223 and the driving wheel 1222 .

[0060] It is understandable that the conveyor belt 121 rotates around the driven wheel 1223 and the driving wheel 1222, and the driving wheel 1222 and the driven wheel 1223 should be located inside the rotation path of the conveyor belt 121. Since the deviation correcting member should contact the cut piece to drive the cut piece to move, the conveyor belt 121 should contact the cut piece.

[0061] It can be understood that the conveyor belt 121 can be a belt, a chain, etc. In order to protect the surface of the cut piece, in this embodiment, the conveyor belt 121 is a belt.

[0062] See also Figure 1 In one embodiment, the number of the driven wheels 1223 is two, and the line connecting the centers of the two driven wheels 1223 and the driving wheel 1222 is a triangular structure.

[0063] It is understandable that when the contact area between the conveyor belt 121 and the cut piece is large, the friction between the conveyor belt 121 and the cut piece is greater, and the pressure per unit area of ​​the cut piece when the conveyor belt 121 drives the cut piece to move is smaller, thereby protecting the surface of the cut piece.

[0064] In this embodiment, in order to increase the contact area between the conveyor belt 121 and the cut piece, any two of the two driven wheels 1223 and one driving wheel 1222 are horizontally arranged along the Y axis so that a section of the conveyor belt 121 can contact the cut piece.

[0065] It is understandable that, since the driving wheel 1222 is connected to the deflection correction motor, in order to prevent the deflection correction motor from being set close to the cut piece and affecting the conveyor belt 121 driving the cut piece, in this embodiment, the two driven wheels 1223 are set on the side close to the cut piece, and the driving wheel 1222 is set on the side far from the cut piece. In other words, the two driven wheels 1223 are set horizontally along the Y axis.

[0066] In other embodiments, the conveyor belt 121 may also be in a non-closed loop. For example, the deflection correction drive 122 includes an unwinding mechanism and a rewinding mechanism, and the two ends of the conveyor belt 121 are respectively connected to the rewinding mechanism and the unwinding mechanism.

[0067] See also Figure 1 In one embodiment, the deflection correction drive 122 further includes a pressure wheel 1224 , which presses the conveyor belt 121 from the outer side of the conveyor belt 121 .

[0068] It can be understood that the function of the pressure wheel 1224 is to subject the conveyor belt 121 to reverse pressure, thereby tensioning it, thereby preventing the conveyor belt 121 from aging, loosening, and wearing after long-term use, and preventing slippage between the conveyor belt 121 and the driving wheel 1222.
