Description

Technical Field

[0001] The invention provides a cuff folding mechanism and a feed guide plate. Background Art

[0002] The cuffs of a garment such as a shirt usually consist of an inner lining and an outer lining, which are sewn together at the end of the cuff. Before the cuffs are sewn together, the inner and outer fabrics of the cuffs are first cut out from the original fabric of the garment. Figure 1A The cuff structure is shown before the fabric is folded and sewn into a finished cuff. The raw materials include cuff fabric 1 and lining 2. The method for making the finished cuff is as follows: Figure 1B As shown, first overlap the lining 2 on the cuff fabric 1, as shown above Figure 1A , you can use a steam iron, etc., then fold the cuff 1 to cover the lining 2, and sew the cuff fabric 1 and the lining 2 together at the fold, such as Figure 1B As shown by the dotted line in .

[0003] The process of folding the cuff fabric 1 and rolling the lining 2 (called cuff folding) is usually achieved using a cuff folding mechanism. Figure 1C is a spatial image diagram of a known cuff folding mechanism 10, Figure 1D is Figure 1C A side view of the dotted portion of the cuff folding mechanism 10 along the longitudinal direction d1.

[0004] like Figure 1C and Figure 1D As shown, the known cuff folding mechanism 10 is composed of a first stop plate 15 , a folding plate 14 , a second stop plate 13 , and a folding guide plate 12 , which are sequentially overlapped and fixed on a positioning plate (SET plate) 16 .

[0005] Figure 1E and Figure 1F 1 is a schematic diagram of the cuff folding process using the cuff folding mechanism 10. Specifically, after the lining 2 and the cuff fabric 1 are ironed, as shown in FIG. Figure 1A , pushed from the front along the direction d2 into the cuff folding mechanism 10, the end of the cuff fabric 1 is sent to the lower groove of the folding plate 14 until it touches the second stop plate 15, as shown Figure 1E As shown. Continue to feed the cuff fabric 1, the end portion of the lining 2 will automatically rise and hang on the folding plate 14, and from the folding plate 14, the cuff fabric 1 will slowly fold the lining, as shown. Figure 1F As shown.

[0006] However, when the cuff fabric 1 is wrinkled and wavy, as shown in FIG. Figure 1GAs shown, the end of the cuff fabric 1 may not be able to pass through the lower groove of the folding plate 14. Specifically, when the height of the wave pattern at the end of the cuff fabric 1 is greater than the height of the lower groove of the folding plate 14, the end of the cuff fabric 1 will contact the front end of the folding plate and cannot pass through the lower groove of the folding plate 14, thus failing to complete the pre-set cuff folding operation. When this problem occurs, troubleshooting takes time, reducing production efficiency.

[0007] Therefore, it is necessary to improve the cuff folding mechanism to solve the above shortcomings. Summary of the Invention

[0008] Problems to be solved by the invention

[0009] The purpose of this invention is to technically address the aforementioned shortcomings of cuff folding mechanisms. This invention allows the cuff folding mechanism to operate smoothly even when the fabric ends are wavy. It also shortens cuff folding time and improves production efficiency.

[0010] To achieve the above objectives, from a first aspect, the cuff folding mechanism of the present invention has a longitudinal direction and includes: a first stop plate located on the positioning surface of a positioning plate, the first stop plate including a first stop surface extending longitudinally on its front edge; a second stop plate located on the first stop plate, the second stop plate including a second stop surface extending longitudinally on its front edge; a folding plate located between the first and second stop plates, the folding plate including a folding end portion extending longitudinally and protruding forwardly beyond the first and second stop surfaces to form a receiving guide groove between the folding plate and the positioning plate; and a feed guide plate located on the second stop plate, the feed guide plate including a base and a guide end portion. The guide end portion protrudes forwardly beyond the folding end portion of the folding plate to form a folding guide groove between the feed guide plate and the folding plate, and a state turning groove is formed between the folding end portion of the folding plate and the guide end portion. The guide end portion includes a front edge, a feed guide end portion, and a feed receiving surface extending from the front edge to the feed guide end portion. The feed receiving surface is inclined relative to the positioning surface from the front edge to the feed guide end portion, so that the height of the front edge relative to the positioning surface of the positioning plate is greater than the height of the feed guide end portion relative to the positioning surface of the positioning plate.

[0011] According to a solution, a height of the front edge relative to the positioning surface of the positioning plate is greater than a height of the folded end portion relative to the positioning surface of the positioning plate.

[0012] According to a solution, a height of the feed guide end portion relative to the positioning surface of the positioning plate is smaller than a height of the folding end portion relative to the positioning surface of the positioning plate.

[0013] According to the proposed solution, the cuff folding mechanism further includes a folding guide plate positioned between the feed guide plate and the second stop plate. The folding guide plate is detachably mounted to the feed guide plate at a base. The base includes an adjustment slot extending perpendicular to the longitudinal direction. The cuff folding mechanism further includes a fixing member for securing the feed guide plate to the folding guide plate at the base via the adjustment slot.

[0014] According to the solution, the cuff folding mechanism further comprises a height adjustment plate located between the base and the folding guide plate so as to adjust the height of the feed guide end portion of the guide end portion relative to the positioning surface of the positioning plate.

[0015] According to an aspect, the height adjustment plate is made of a material selected from the group consisting of metals, alloys, plastics, composite materials and combinations thereof.

[0016] According to the solution, the fixing member is a screw.

[0017] According to the solution, the first stop plate, the second stop plate and the folding plate are all flat plate structures.

[0018] According to the solution, the folding guide plate is a flat plate structure.

[0019] According to a solution, the guide end portion has a V-shaped structure when viewed in the longitudinal direction.

[0020] According to an aspect, the first stopper plate, the second stopper plate, the folding plate and the feed guide plate are all made of a material selected from the group consisting of metal, alloy, plastic, composite material and combinations thereof.

[0021] In a second aspect, the present invention provides a feed guide plate for use in a cuff folding mechanism for guiding the folding of a cuff fabric having a longitudinal direction. The feed guide plate comprises a base and a guide end portion. The base extends longitudinally and includes a substantially flat folding guide surface facing the cuff fabric, the folding guide surface defining a reference plane including the folding guide surface facing the cuff fabric. The guide end portion extends longitudinally and includes, on a side facing the reference plane of the cuff fabric, a leading edge, a feed guide end portion, and a feed receiving surface extending from the leading edge to the feed guide end portion, wherein the feed receiving surface faces the cuff fabric. The feed receiving surface is inclined relative to the reference plane from the leading edge toward the feed guide end portion, such that the distance from the leading edge to the reference plane is shorter than the distance from the feed guide end portion to the reference plane.

[0022] According to a solution, the base includes an elongated adjustment slot extending in a direction perpendicular to the longitudinal direction.

[0023] According to a solution, the guide end portion is V-shaped when viewed from the longitudinal direction.

[0024] According to an aspect, the feed guide plate is made of a material selected from the group consisting of metals, alloys, plastics, composite materials and combinations thereof. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] Figure 2 3. This is a spatial image diagram of the cuff folding mechanism 100 of the present invention. Figure 3 The cuff folding mechanism 100 of the present invention is Figure 2 Enlarged spatial image of the upper dotted line part. Figure 4 is along the longitudinal direction d1 Figure 2 A side view of the dotted portion of the upper cuff folding mechanism 100. The direction d1 is the longitudinal direction of the cuff folding mechanism 100.

[0080] like Figures 2 to 4 As shown, the cuff folding mechanism 100 includes a first stopper plate 150 located on a positioning plate 160 (also referred to as a SET 160 plate), a second stopper plate 130 located on the first stopper plate 150, a folding plate 140 located between the first stopper plate 150 and the second stopper plate 130 and protruding further forward than the first stopper plate 150 and the second stopper plate 130, and a guide plate 110 located on the second stopper plate 130. The guide plate 110 includes a folding guide plate 120 and a feed guide plate G located above the folding guide plate 120.

[0081] According to the described solution, the positioning plate 160 includes a nearly planar positioning surface 161, with the longitudinal direction d1 being parallel to the positioning surface 161. The first stop plate 150, the second stop plate 130, and the rectangular flat plate-shaped folding plate 140 overlap and extend in the longitudinal direction d1. The first stop plate 150 includes a first stop surface 151 located at an extension front angle parallel to the longitudinal direction d1. The second stop plate 130 includes a second stop surface 131 located at an extension front angle parallel to the longitudinal direction d1. The folding plate 140 includes a folded end portion 141 located at an extension front angle parallel to the longitudinal direction d1. The rectangular flat plate-shaped folding guide plate 120 protrudes forward through the second stop surface 131, and the front edge 121 extends in the longitudinal direction d1. According to the described solution, the front edge 121 is slender.

[0082] The cuff folding mechanism 100 is arranged to form a feed guide trough 142 between the positioning plate 160 and the folding plate 140, and a folding guide trough 122 between the folding plate 140 and the folding guide plate 120. The folding guide trough 122 includes a planar inward-facing folding guide surface 123 and a narrow, curved outward-facing folding guide surface corresponding to the elongated leading edge 121. The distance from the lower edge of the folding end 141 to the positioning plate 160 is referred to as the height h2 of the folding end 141. According to the described scheme and the figures, the height h2 is equal to the thickness of the first stop plate 150.

[0083] According to the described solution, the feed guide plate G includes a flat base G1, which facilitates position adjustment and is secured by a folding guide plate 120. A guide end G2 extends parallel to the longitudinal direction d1. The guide end G2 of the feed guide plate G projects forward through a folded end 141, lower than the base G1 on the positioning surface 160 side. The guide end G2 includes a feed guide end 111, which is positioned lower than the positioning plate 160. A portion of the feed receiving device 112 includes a feed receiving surface 112a that slopes downward from a leading edge 112b to the feed guide end 111, thereby sloping in relation to the positioning surface 161. As a result, the distance between the feed receiving surface 112a of the feed receiving device 112 and the positioning plate 160 gradually decreases horizontally from the leading edge 112b toward the guide end G2. It is important to note that, according to the described solution, the leading edge 112b and the feed guide end 111 extend in the longitudinal direction d1 and are parallel to the positioning surface 161.

[0084] The distance between the feed receiving surface 112a and the positioning surface 160 reaches its maximum at the leading edge 112b, referred to as the height h3 of the leading edge 112b, and reaches its minimum at the feed guide end 111, referred to as the height b of the feed guide end 111. The open groove between the feed guide end 111 and the positioning plate 160 forms the feed guide groove 111a of the cuff folding mechanism 100. A state deflection groove 114 is located between the guide end G2 and the folding end 141, and is defined as being horizontally located between the folding end 141 and the guide end G2. According to the embodiment shown in the drawing, the guide end G2 is V-shaped when viewed from the direction d1.

[0085] According to the described solution, the height b of the feed guide end 111 is less than the height h2 of the folded end 141. The height h3 of the leading edge 112b is greater than the height h2 of the folded end 141.

[0086] The base G1 of the feed guide plate G includes an adjustment slot 113 for adjusting the position of the feed guide plate G in the horizontal direction (ie, parallel to the positioning surface 160 in the direction d2). Figure 3 As indicated by the arrows on both ends, the feed guide plate G and the folding guide plate 120 are fixed. Specifically, the elongated adjustment slot 113 extends from the cuff folding mechanism 100 from front to back (i.e., extends along the direction d2) and can be used to horizontally adjust the distance between the guide end G2 and the first stop surface 151.

[0087] The first stopper plate 150, the folding plate 140, and the second stopper plate 130 can be fixedly mounted on the surface of the positioning plate 160 by bolt and nut fixing members. The folding guide plate 120 and the feed guide plate G can be fixed to the second stopper plate 130 by bolt or screw fixing members 115 through the adjustment slot 113.

[0088] Figures 5A to 5G The figure depicts the process of cuff folding using the cuff folding mechanism 100 according to the present invention. The cuff material includes the lining 2 and the cuff fabric 1 flatly attached, and is placed on the positioning plate 160 ( Figure 2 ), so that the end of the lining 2 is parallel or nearly parallel to the feed receiving surface 112a, that is, along the longitudinal direction d1. The cuff material is pushed along the direction d2 to enter the feed receiving surface 112a, as shown in FIG. Figure 5A When the wavy edge of the cuff fabric 1 contacts the feed receiving surface 112a of the guide end G2, the end of the fabric is transferred to the feed receiving surface 112a, thereby becoming concave and gradually descending toward the feed guide end 111, as shown in FIG. Figure 5B As shown. The end of the cloth continues to descend to the guide end 111 and passes through the feed guide groove 111a. After passing through the feed guide groove 111a, the end of the cloth continues to enter the receiving guide groove 142, as shown. Figure 5CAfter entering the receiving guide groove 142, the end of the cloth moves until it touches the first stop surface 151 of the first stop plate 150, as shown. Figure 5D As shown, stop the preparation state and turn.

[0089] Continue to feed the cuff fabric 1, the lining end 2a will automatically rise to the state turning groove 114 when it is attached to the cuff fabric 1, and then cross the state turning groove 114 and rise above the folding end 141 of the folding plate 140, and go to the folding guide groove 122, as shown in FIG. Figure 5E When the lining end portion 2a enters the folding guide groove 122, the folded cloth wraps around the lining end portion 2a due to the action of the folding end portion 141 of the folding plate 140, as shown in FIG. Figure 5F Continue to push the cuff fabric 1 in so that the fabric folds over the lining end 2a until the lining end 2a has passed through all the folding guide grooves 122 and touches the second stop surface 131 of the second stop plate 130, as shown. Figure 5G At this point, the cuff fabric 1 can no longer be pushed and the folding process is completed.

[0090] As described above, the elongated adjustment slot 113 can horizontally adjust the distance of the guide end G2, thereby adjusting the distance between the feed guide end 111 of the feed guide plate G and the first stop surface 151. The horizontal adjustment distance of the guide end G2 can be adjusted by loosening the fixing member 115 ( Figure 3 ) and the method of moving the feed guide plate G back and forth is easily accomplished, that is, along the direction d2, along the adjustment groove 113, and then re-fixing the member 115 to fix the feed guide plate G and the folding guide plate 120. As a result, the distance a from the feed guide end 111 to the first stop surface 151 is obtained.

[0091] Figure 6 This is a partial spatial image of another embodiment of a cuff folding mechanism 1000 according to the present invention. The structure of this embodiment of the cuff folding mechanism 1000 is similar to the previously described cuff folding mechanism 100, but the cuff folding mechanism 1000 further includes a height adjustment pad 180 positioned between the base G1 of the feed guide plate G and the folding guide plate 120 to adjust the height of the feed guide plate G. This method allows the height of the guide end G2 relative to the positioning plate 160 to be adjusted. Specifically, due to the addition of the height adjustment pad 180, the height of the guide end G2 relative to the positioning plate 160 is increased due to the thickness of the height adjustment pad 180. Consequently, the height h3' of the leading edge 112b relative to the positioning plate 160 and the height b' of the feed guide end 111 relative to the positioning plate 160 are also increased due to the thickness of the height adjustment pad 180.

[0092] The height of the guide end G2 can be easily adjusted by first removing or loosening the fixing member 115, inserting a height adjustment pad 180 of the appropriate height, and then re-using the fixing member 115 to secure the feed guide plate G to the folding guide plate 120. The distance between the guide end G2 of the feed guide plate G and the first stop surface 151 can also be horizontally adjusted using the same method described above for the cuff folding mechanism 100 to obtain the desired distance a' between the feed guide end 111 and the first stop surface 151.

[0093] According to the above-described solution, the guide plate 110 of the cuff folding mechanism 100 is composed of a feed guide plate G and a folding guide plate 120 assembled together. Alternatively, the guide plate 110 can be constructed as a conjoined structure, with the feed guide plate G and the folding guide plate 120 interconnected. In this solution, the guide plate 110 can be considered to comprise a folding guide plate, which is integrally connected to the base G1 and the guide end G2.

[0094] According to the above-described embodiment, the guide plate 110 of the cuff folding mechanism 100 is composed of a feed guide plate G and a folding guide plate 120 mounted together. According to another embodiment, the cuff folding mechanism 100 lacks the folding guide plate 120 and instead comprises only the first stop plate 150, the folding plate 140, the second stop plate 130, and the guide plate G. The guide plate G comprises a base G1 and a guide end G2. In this embodiment, the base G1 of the guide plate G functions as the folding guide plate 120. Specifically, the underside of the base G1 forms a folding guide surface, functioning as the folding guide surface 123 of the folding guide plate 120.

[0095] According to the above solution, the height b of the feed guide end 111 is less than the height h2 of the folding end 141, so that the cloth end can easily move into the receiving guide groove 142. However, in some cases, this condition is not necessarily required to complete the folding process. In other words, the height b can be greater than the height h2, and the folding process can still be completed by adjusting the distance a accordingly.

[0096] According to the above-described scheme, the cuff folding mechanism does not include the folding guide plate 120 or the guide end G2. Instead, it descends toward the positioning plate 160 and includes a leading edge 112b, a feed guide end 111, and a feed receiving surface 112a that slopes from the leading edge 112b to the feed guide end 111. This allows the height distance from the leading edge 112b to the positioning plate 160 to be greater than the height distance from the feed guide end 111 to the positioning plate 160. Alternatively, the feed receiving surface 112a can be considered to slope from the leading edge 112b to the feed guide end 111, resulting in a height distance from the leading edge 112b to a reference plane (defined as a plane containing the guide surface of the base G1) that is less than the height distance from the feed guide end 111 to the reference plane. According to this scheme, the leading edge 112b, the feed guide end 111, and the feed receiving surface 112a located on the reference plane face the direction of the cuff folding fabric 1. According to other solutions, the leading edge 112b and the feed guide end 111 may be located on both sides of the reference plane, that is, the height h3 of the leading edge 112b is greater than the total thickness of the three plates 150, 140, and 130.

[0097] According to various embodiments, the positioning plate 160, the first stop plate 150, the folding plate 140, the second stop plate 130, the folding guide plate 120, the feed guide plate G and the height adjustment plate 180 are made of a material selected from the group consisting of metals, alloys, plastics, composite materials and their combination materials.

[0098] The present invention is not limited to the above-described parts. In fact, based on personal understanding of the technical field of the present invention, corresponding variations and modifications can be made.
