Description

  The present invention relates to a method for manufacturing a glove in which an anti-slip resin is formed on at least the palm side.

  In general, gloves such as work gloves are made by sewing or knitting according to the shape of a person's hand. In order to prevent slipping, gloves with a plurality of rubber materials attached to the palm side have been proposed. Yes. Such a rubber material is formed on at least the palm side so as not to slip when a person wearing a work gloves grips an object.

  However, in the glove, there is a problem that when the rubber material is formed in a wide range on the palm side in order to enhance the anti-slip effect, the air permeability is impaired and the wearing feeling is deteriorated. In addition, after forming a rubber material covering a relatively wide area on the palm of the hand, it may be possible to make a plurality of holes to ensure air permeability, but in that case, a drilling process is separately required. There is a problem that workability deteriorates.

  However, the applicant of the present invention is to attach a hand that is sewn or knitted to a hand mold having a surface having a micro-convex shape, and project the micro-convex shape from the seam or stitch of the hand. By attaching a polymer resin in a molten state to the original hand, it has been studied to form a vent simultaneously with the adhesion of the polymer resin. Thereby, workability | operativity can be improved by forming a ventilation hole, without passing through a separate process. In addition, since this prior art does not relate to the literature known invention, there is no prior art document information to be described.

  However, in the glove as described above, since the minute convex shape is fixed in a protruding state on the surface of the hand mold, when trying to attach the hand to the hand mold, the minute convex shape is caught on the hand. Therefore, there is a problem that it is difficult to perform a good mounting operation. In addition, even after removing the original hand from the hand mold after the polymer-based resin is attached and dried, there is also a problem that a fine convex shape is caught on the original hand, making it difficult to perform a good removal operation. .

  The present invention has been made in view of such circumstances, and can form a non-slip resin over a wide range at least on the palm side while ensuring air permeability, and undergoes a separate process. It is an object of the present invention to provide a method of manufacturing a glove that can improve workability by forming a vent hole without any problem and can improve the work of attaching and detaching the hand to the hand mold.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIG. 1, the glove according to the present embodiment has an anti-slip material 2 formed on the palm side of the hand 1 that has been sewn or knitted. The anti-slip material 2 is made of a polymer resin (for example, natural rubber, synthetic rubber, plastic or polyurethane), and is formed in a film shape over substantially the entire area of the palm side of the hand 1. This prevents a person wearing gloves from slipping when grasping an object.

  Further, as shown in FIG. 1B, the anti-slip material 2 is formed with a plurality of ventilation holes 2a corresponding to the positions of the stitches 1a of the hand 1, and the inside of the glove is interposed through the ventilation holes 2a. Communicated with the outside air. Thereby, when the person who put on the glove sweats, etc., it can escape from the vent hole 2a and the inside of the glove can be prevented from being steamed, so that the fitting comfort can be improved.

Next, the manufacturing method of the said glove is demonstrated.
First, as shown in FIG. 2, a hollow hand mold 3 imitating a human hand is prepared, and the hand 1 is mounted on the hand mold 3 (mounting process). The hand mold 3 is a hollow shape obtained by molding an aluminum material into a desired shape, and the size and the degree of bending of a finger or the like are set based on the original hand 1 to be worn. The hand 1 is formed into a knit shape by sewing or knitting, and has a stitch 1a (see FIG. 1B).

  Further, on the palm side of the hand mold 3 and on the portion to which the anti-slip material 2 (polymer-based resin) is to be attached, a plurality of intrusion holes 3a that connect the inside and the outside of the hand mold 3 are formed. In addition, a movable member 5 and a cam portion 7 (operation means) in which a grip portion 6 is formed are inserted into the hand mold 3. The movable member 5, the gripping portion 6 and the cam portion 7 constitute the protrusion / distraction means of the present invention, and a protrusion 4 described later can be arbitrarily protruded / retracted via the protrusion / disengagement hole 3 a. .

  As shown in FIG. 3, the movable member 5 is composed of a plate-like member having a shape substantially following the palm portion of the hand 3, and a plurality of protrusions 4 having a sharp tip are formed on the surface thereof. Yes. The size of the protrusion 4 is smaller than the diameter of the stitch 1a of the original hand 1, and the protrusion 4 protrudes from the surface of the hand mold 3 as shown in FIG. When mounted on the mold 3, the protrusion 4 can be inserted into the stitch 1a.

  The movable member 5 is slidably supported by a rod 8 (see FIGS. 2 and 3) that protrudes from the inner surface of the hand mold 3, and the inner surface of the hand mold 3 and the movable member 5 in the rod 8. A return spring 9 is disposed between the two. On the other hand, a cam portion 7 in which a grip portion 6 is formed is disposed below the movable member 5, and the peripheral surface (profile surface) of the cam portion 7 is in contact with the substantially central lower surface of the movable member 5. It is in a state of contact.

  The gripping portion 6 protrudes to the outside from the hand mold 3 and can be gripped and rotated by an operator. However, before the grip portion 6 is rotated, as shown in FIG. 4, the movable member 5 is in a state of being separated from the inner surface of the hand mold 3, and the protrusion 4 is immersed in the surface of the hand mold 3. It is in a state. Then, when the cam portion 7 rotates (1/4 rotation) as the gripping portion 6 is rotated, the movable member 5 is urged by the urging force of the return spring 9 by the action of the cam, as shown in FIGS. The surface (the surface on which the protrusion 4 is formed) is brought close to the inner surface of the hand mold 3, and the protrusion 4 protrudes from the surface of the hand mold 3.

  Further, when the gripping portion 6 is further operated to rotate the cam portion 7 (further 1/4 turn from the state of FIG. 5), the push-up force due to the action of the cam is released, and the movable member 5 is attached to the return spring 9. It returns to the original position (position shown in FIGS. 3 and 4) by the force and its own weight. That is, by rotating the grip 6, the protrusion 4 can freely appear and disappear from the surface of the hand mold 3 through the appearance hole 3 a.

  Therefore, in the mounting process of mounting the hand 1 on the hand mold 3, the cam portion 7 is in the state shown in FIG. 4, and the protrusion 4 is immersed in the intruding hole 3a (the state in FIG. 2). ). After the hand 1 is mounted on the hand mold 3 as described above, the operator rotates the cam section 7 by 1/4 while gripping the grip section 6, whereby the projection section 4 is moved to the hand mold 3. The molten polymer resin is adhered to the palm side of the hand 1 in that state (resin adhesion step).

  For example, the resin adhesion operation may be a method in which a molten polymer resin is stored in a predetermined tank and the palm side of the hand 1 is dipped and impregnated for a predetermined time (dipping method), or the molten resin is used as the original hand. Various general-purpose techniques such as a method of dripping and soaking the palm of one hand (shower method) can be employed. The molten state of the polymer resin is sufficient as long as it can be applied to the hand 1 and may be in the form of a sol or a gel.

  At this time, as shown in FIG. 7, the top 4 a of the protrusion 4 protruding from the surface of the hand mold 3 is inserted through the stitch 1 a of the hand 1, while the resin film (the anti-slip material 2 is passed through the subsequent drying). Projecting slightly). That is, the resin film obtained in the resin adhering step is formed at a position lower than the top 4a of the minute convex portion 4, and in this state, the adhering resin is dried and solidified (drying step). The dried and solidified resin functions as the anti-slip material 2 in the present embodiment. Here, in the drying process, when the polymer resin in the molten state used is a thermosetting resin, it is solidified by heating and adding calories, and in the case of other resins, it is solidified by adding an accelerator or the like. You may let them.

  After the drying process as described above, the operator rotates the cam portion 7 while rotating the grip portion 6 while holding the grip portion 6 again, so that the projection portion 4 is immersed in the protrusion / depression hole 3a of the hand mold 3. Let In this state, the hand 1 is removed from the hand mold 3 (mold release process), and a series of manufacturing processes is completed. A plurality of vent holes 2a are formed. Therefore, even if the anti-slip material 2 is formed over a wide range on the palm side as in this embodiment, the air permeability can be ensured, and the air holes 2a are formed simultaneously with the adhesion of the polymer resin during the resin adhesion process. Therefore, the workability can be improved by forming the air holes without going through a separate process.

  Further, the protrusion 4 can be moved in and out with respect to the surface of the hand mold 3, and the protrusion 4 is immersed when the hand 1 is attached to the hand mold 3 (mounting process) and when it is removed (release process). In addition, when the polymer-based resin is adhered (resin adhesion process), it is possible to avoid inadvertent catching when the original hand 1 is attached / detached, and the attaching / detaching work of the original hand 1 to the hand mold 3 is improved. be able to. Furthermore, by changing the profile surface of the cam portion 7 and the protrusion of the protrusion 4 according to the polymer resin to be attached, the formation of the air holes 2a in the resin attachment step can be performed more reliably. In addition, by adjusting the diameter of the protrusion 4 (with replacement of the movable member 5), the formed air hole 2a can be made to have an arbitrary size.

  Furthermore, according to the present embodiment, since the protrusion 4 can be arbitrarily protruded and retracted through the protrusion hole 3a, the protrusion 4 can be reliably moved in and out with a simple configuration. The work of detaching the original hand 1 can be further improved. In addition, since the projecting and retracting means for projecting and projecting the protrusion 4 from the surface of the hand mold 3 is constituted by the movable member 5 and the cam portion 7 (operating means) on which the grip portion 6 is formed, the movable member 5 is provided. A plurality of hand molds 3 provided with can be shared by a single operation means, and the manufacturing cost can be reduced.

  Although the present embodiment has been described above, the present invention is not limited to this. For example, as shown in FIGS. 8 and 9, the notch 3b is formed on the opening side edge of the hand mold 3, You may make it comprise the fixing rod 11 which can be fitted to this notch 3b. The notch 3b and the fixing rod 11 constitute the fixing means of the present invention. By the fixing means, the movable member 5 comes close to the inner surface of the hand mold 3 and the protruding portion 4 is in the protruding and protruding hole 3a. The rotation of the operating means (cam portion 7) can be restricted in a state protruding from the head.

  Specifically, the fixing rod 11 is integrated with the gripping portion 6 by being penetrated and fixed in the radial direction of the gripping portion 6, while the fixing plate 10 is opened to the opening of the hand mold 3 through the bolt B. The coil spring 12 is interposed between the fixing plate 10 and the fixing rod 11 and fixed to the side edge. Thereby, since the fixed rod 11 is always urged to the hand mold 3 side, it is possible to avoid the cam part 7 and the grip part 6 from coming out of the hand mold 3.

  Further, when the movable member 5 is close to the inner surface of the hand mold 3 and the protruding portion 4 protrudes from the protruding and recessed hole 3a, the fixing rod 11 is fitted into the notch 3b, thereby operating means (cam portion 7). Can be controlled. Therefore, the state in which the protruding portion 4 protrudes can be reliably maintained, and workability can be improved. However, if the gripping part 6 is moved forward (left side in FIG. 9) against the biasing force of the coil spring 12, the fixing rod 11 is separated from the notch 3b. The rotation of the cam portion 7 by the fixing means is released, and the movable member 5 is separated from the inner surface of the hand mold 3 by the action of the cam, so that the protrusion 4 is in the protrusion / retraction hole. It will be in the state immersed in 3a.

  In addition, the code | symbol 6a in the same figure has shown the convex-shaped part formed in the front end side of the holding | grip part 6, and while using this convex-shaped part 6a, the grip of the holding | grip part 6 is favorable, a cam part is used as a mark. 7 (whether the movable member 5 is close to the inner surface of the hand mold 3 and the protrusion 4 protrudes, or the movable member 5 is separated from the inner surface of the hand mold 3 and the protrusion 4 is immersed) ) Can be easily grasped.

  By the way, although the projection part 4 is made into the shape shown in FIG. 7, it is good also as projection part 4 'which has a linear surrounding surface over the movable member 5, for example, as shown in FIG. . In this case, since the diameter of the base side (movable member 5 side) can be made smaller than the substantially conical projection 4, the hand 1 is attached to the hand mold 3 so that the projection 4 ′ is inserted into the intrusion hole 3 a. It is possible to prevent the protrusions from being caught on the stitches 1a of the original hand 1 and being raised when the protrusions 1 are projected.

  Further, in this embodiment, the anti-slip material 2 is formed only on the palm side of the hand 1, but in addition to the formation of the anti-slip material 2 on the palm side of the hand 1, the anti-slip material is also provided on the back side of the hand. 2 may be formed. In this case, when the movable member 5 having a plurality of protrusions 4 formed on the back side of the hand 3 is disposed, and the cam portion 7 is rotated by rotating the gripping portion 6, the palm side and the back of the hand. It is preferable that both side protrusions 4 protrude at the same time.

  Further, it is sufficient that the protrusion 4 can be protruded and retracted from the surface of the hand mold 3. In addition to the protruding and retracting operation of the protruding part 4 by the action of the cam as in this embodiment, the protruding and retracting operation by an air cylinder or an oil cylinder, or a motor It is good also as the appearance operation | movement by the isoelectric drive source. In addition, you may make it form the uneven | corrugated shape etc. which can exhibit the anti-slip | skid effect more on the surface of the anti-slip | skid material 2 formed by drying and solidifying after a drying process. In this case, the concavo-convex shape may be imparted by a mold or by melting the surface of the anti-slip material 2 with a drug or the like, or may be imparted so as to become a pattern, characters, symbols or the like that function as a design as a whole. Good. Furthermore, the projecting portion 4 of the hand mold 3 may be formed at a predetermined position so that the formed air hole 2a can be seen as a predetermined design or characters drawn with dots, thereby improving the design. .

  A plurality of protrusions projecting from the polymer resin adhered in the resin adhesion process are formed at the site to which the hand-shaped polymer resin is adhered, and the protrusions can be projected and retracted from the surface of the hand mold. If it is the manufacturing method of a glove, the method using the hand type | mold with which the external shape differs, the hand type | mold with which the other function was added, etc. may be sufficient.
