2. Description of the Related Art In a dipping method in which a glove forming die is dipped in a solution of synthetic resin, rubber or the like to form a glove, an ear portion (unnecessary portion) remaining at the glove mouth portion (hand inlet portion) is removed to remove edges. The process of partial treatment is indispensable, and in the past, after the gloves were peeled off from the mold, the worker successively cut them with a cutter or the like. Therefore, the applicant of the present invention first invented a glove forming die in order to eliminate the troublesome work of removing the ears by the cutter in the glove manufacturing process (Japanese Patent Application No. 57-113915). That is, the mold is provided with a ridge having a pointed tip protruding in a blade shape in the peripheral area of the mouth (hand entrance) of the mold body, and the solution adhered to the pointed portion by surface tension. By locally forming a thin film shape, the excessively formed ear portion can be easily peeled off by hand from the thin film portion formed at the apex portion.

However, even with the conventional manufacturing method using the above-mentioned mold, the result is that the operator is too tidy and has to manually remove the ears. However, it cannot be said that the improvement of the work labor was sufficiently made, and the work efficiency was poor, and there was a demand for automation of the whole manufacturing process, and improvement in this type of glove manufacturing method is desired. There was also a background. Further, there is room for improvement in releasability at the time of removing the ears, and since the ears are unnecessary parts, it is preferable from the viewpoint of cost that the raw material adhesion amount is as small as possible.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to automate the work of removing the ears of gloves formed on the mold surface by the dipping method. In addition to contributing to the improvement of work effort and work efficiency, it is possible to sufficiently meet the demand for automation of this type of glove manufacturing method, and further to improve the releasability when removing the ears and reduce the amount of raw material adhered. That is.

[0005]

[Means for Solving the Problems] To achieve the above object, the technical means of the present invention is to synthesize a glove forming die in which a pointed ridge portion is provided in the peripheral region of the mouth of the die body. Immerse it in a solution of resin or rubber to locally form a thin film only on the tips of the ridges to form a film on the entire mold, and then remove the ears that consist of the mold rotation transfer mechanism and the ears removal belt. To the mechanism, and the mold rotating and transporting mechanism rotates the mold in a desired direction around the axis, and on the surface of the removal belt whose speed is adjusted to a speed different from the rotation speed of the mold, The forming die is rolled while abutting the formed ear portion between the protruding portion and the base edge of the die, and the edge portion is stripped off by the friction caused by the speed difference. It is to be.

Further, a glove forming die having a pointed ridge portion around the mouth of the die body is dipped in a solution of synthetic resin or rubber, and only the tip of the ridge portion is locally applied. The entire die is formed into a thin film and then moved to the ear removal mechanism that is composed of the die rotation transfer mechanism and the ear removal belt, and the molding die is centered around the shaft center by the die rotation transfer mechanism. And a ears part formed on the surface of the removal belt, which is rotated in a desired direction as a mold and is rotationally adjusted in a direction different from the rotation direction of the mold, between the ridge and the base edge of the mold. It is also possible to roll the molding die while contacting with each other and peel off the ear portion by friction generated by the rotation in the different direction to treat the edge portion.

Further, it is also possible to use a molding die having a fluorine-based coating film on the surface of the ear portion film-forming surface between the protruding portion and the base end edge.

EXAMPLE An example of the present invention will be described below. A glove forming mold 1 used in the manufacturing method of the present invention has a peripheral region of a mouth part 3 (hand entrance part) of a mold body 2 formed in a hand shape. A glove body film-forming surface 8 for forming a film on the glove body A from the tip 6 of the projection to the fingertip 7 An endless chain plate 1 in which the mold 1 is provided in a manufacturing line is formed from the tip 6 to the base edge 4 as an ear film forming surface 9 on which the ear B is formed.
3 is attached to a support shaft 15 provided on the mold 3, and the mold 1 is adjusted to a predetermined mold temperature, and then the whole mold is immersed once or plural times in a vinyl chloride solution having a desired composition in a suspended state. When the vinyl chloride paste is adhered and pulled up on the entire surface of the above, the paste is locally adhered to the tip end 6 of the ridge portion in the form of a thin film due to surface tension, and is semi-cured to form a film, and then the ear portion removing mechanism 11 Move to.

The support shaft 15 provided on the chain plate 13 is constructed so as to be rotatable about the shaft center at an intermediate portion and can be laid sideways on the holding portion 14 fixed on the chain plate 13 (y Direction), the glove mold 1 is connected to the tip and supported to move along the manufacturing line (z direction). That is, the glove forming mold 1 which is held in a suspended state during the dipping process and formed into a film is moved while being supported by the main guide walls 24 provided on both sides of the chain plate 13 in the line direction in a standing state. In the ear portion removing step, the die 1 is supported sideways and moved by the sub-guide wall 25 arranged in parallel with the chain plate 13 with the support shaft contact surface 26 facing upward.

Then, the glove mold 1 in the state of surface film formation that has moved to the ear portion removing mechanism 11 is laid down sideways around the shaft attachment portion 16 of the support shaft 15 by the sub guide wall 25, and the ear portion is removed. The ear part B is stripped off by the ear part removal belt 21 while being rolled counterclockwise by the mold rotation transfer mechanism 12 of the mechanism 11, and the process moves to the next surface treatment step and glove reversal separation step. Further, the surface treatment step may be performed before the ear portion removing step, and can be appropriately changed. In the present embodiment, the glove mold 1 is rotated counterclockwise (in the x direction), but it may be rotated clockwise without any limitation.

As described above, the ear removing mechanism 11 is composed of the mold rotating and transferring mechanism 12 and the ear removing belt 21, and the mold rotating and transferring mechanism 12 is constructed so as to be rotatable about the shaft center in the middle thereof. The support shaft 15, the pinion 18 integrally provided around the rotation part 17 of the support shaft 15, and the rack 19 disposed below the pinion 18 in parallel with the chain plate 13. The pinion 18 meshes with the rack 19 as the chain plate 13 moves, and the pinion 18 moves upward from the rotating portion 17 a 15a.
Rotates counterclockwise to rotate the glove forming mold 1.

Further, the support shaft 15 has a ridge 20 circumferentially provided above the circumferential position of the pinion 18.
0 is brought into sliding contact with the support shaft contact surface 26 of the sub guide wall 25.

On the other hand, the ear removal belt 21 is used for the glove forming mold 1.
With a different speed, for example, in the same direction (x 'direction) as the glove forming mold 1 and an endless belt of a desired length whose speed is adjusted to be faster than the mold rotating speed. The belt surface (peeling surface) 22 is made to face the ear portion film-forming surface 9 of the mold 1, and the rack 19 is formed.
It is arranged in parallel with.

Regarding the rotational speed of the glove forming mold 1 and the rotational speed of the ear portion removing belt 21, for example, the difference in peripheral speed between them is 6 m.
/ Min.

Further, as shown in the drawing, an ear separating roll (pretreatment step) 28 is provided in front of the ear removing belt 21, and the ear B is previously rotated by rotating the roll 28 in front of the ear removing belt 21. It may be separated from the tip 6 of the ridge portion to improve the stripping efficiency of the ear part removal belt 21, and in the present embodiment, a pressing part 29 is provided to bring the glove forming mold 1 into close contact with the ear part removal belt 21. ing.

Therefore, the ear portion B portion formed between the ridge portion tip 6 and the base end edge of the glove forming die 1 is brought into contact with the surface 22 of the ear portion removing belt 21 and the die is formed. When 1 is rolled, the ears B are caught by the friction generated by the speed difference between the two, and the ears B peeled off along the tips 6 of the ridges formed in a thin film form downward. The glove forming tool 1 including the glove body A whose ears B have been removed and the edges of which have been processed is then supported from the sub-guide wall 25 to the main guide wall (not shown) in the standing state again. Move to the surface treatment step.

Further, in this embodiment, a step 27 is provided on the sub guide wall 25 before the starting end 23 of the ear removing belt 21, and the ridge 20 provided around the support shaft 15 is mounted on the step 27. By temporarily holding the glove forming mold 1 above the ear removing belt 21 and rolling the glove forming mold 1 on the belt 21, the glove forming mold 1 that has moved to the ear removing belt 21 moves to the belt start end 23. I try not to touch them.

Further, even if the belt speed is set to be slower than the mold rotation speed contrary to the above-mentioned embodiment, the ear stripping effect can be similarly obtained and can be appropriately changed.

Therefore, the edge of the glove that has been subjected to the well-known surface treatment step and reverse peeling step after the above-mentioned ear portion removing step has been cleanly treated. The surface treatment process and the reverse peeling process are well known in the art, and therefore the description thereof will be omitted.

As in the ear removing mechanism 11 of the manufacturing method according to the second aspect, the ear removing belt 21 is moved in a direction different from the rotating direction of the glove forming mold 1 (the mold is counterclockwise as shown in the drawing). When the belt is rotated clockwise, the ear portion B formed between the protruding portion 5 and the base end edge 4 of the mold 1 is rotationally adjusted.
Assuming that the mold 1 is rolled while abutting against each other, the ears B formed on the glove mold 1 are peeled off by the friction generated by the rotation of the two in different directions, and the edge treatment is performed in the same manner as above. can do. The rotation speed is not limited in any way, and both may be equal to each other or may be faster than any of them.

Further, in this embodiment, the ear mold is removed with the glove mold 1 lying down, but the ear mold may be removed while the mold 1 is standing. Although not limited, according to the present embodiment, the stripped ear portion B is dropped outside the normal line, which is preferable for cleaning the stripped ear portion (dust). Further, in the present embodiment, the stripping waste collection belt 30 is installed below the ear portion removal belt 21 in the line direction,
It is supposed that the stripped off ear B can be collected and effectively contributed to resource reuse.

Further, in the glove mold 1, as shown in claim 3, a fluorine-based coating film 10 such as fluorine or silicon is formed on the surface of the ear portion film-forming surface 9 from the tip of the protrusion 5 to the base edge 4. If provided, due to the wettability (sliding property) of the above-mentioned fluorine, the releasability at the time of automatically peeling off the ears B attached to the surface of the ears film forming surface 9 by the ears removal belt 21. The amount of vinyl chloride paste forming the ear B, which is originally an unnecessary portion, can be reduced.

A specific example of the above-mentioned fluorine-based film is shown below. Assembled material Ni-F system surface treatment (thickness 30 μm) Adhesion amount 2.5 g to 1.8 g Friction resistance (dynamic) 0.06 μm (500 g vertical load)

In the above embodiment, gloves made of vinyl chloride resin are manufactured, but the invention is not limited to the above vinyl chloride, and other synthetic resins such as urethane and silicone,
Needless to say, the gloves may be rubber or the like, and the gloves may be single gloves, flocked gloves, or the like, and the shape of the edge portion, the wall thickness, and the like may be changed as appropriate, and there is no limitation.

[0025]

According to the present invention, a glove forming die having a pointed ridge on the periphery of the mouth of the die body is dipped in a solution of synthetic resin, rubber or the like to form only the tip of the ridge. Is locally formed into a thin film to form a film on the entire mold, and then the mold is moved to an ear removing mechanism composed of a mold rotating transfer mechanism and an ear removing belt, and the mold is transferred by the mold rotating transfer mechanism. A film is formed between the ridge and the base edge of the mold on the surface of the removal belt which is rotated in a desired direction around the axis and is adjusted to a speed different from the rotation speed of the mold. Since it is a glove manufacturing method in which the mold is rolled while abutting the ears, and the ears are stripped off by the friction caused by the difference in speed, edge treatment is performed, so that the conventional workers are careful and manual. The ear removal work of gloves that was performed by Automatically at Inn, and will be reliably performed, model improves reduction and work efficiency of the work effort, it is possible to sufficiently respond to automation requirements in this type of glove manufacturing method.

Further, the removing belt in the ear removing mechanism is rotationally adjusted in a direction different from the rotating direction of the mold to remove the ear portion formed between the protruding portion and the base edge of the mold. As a glove manufacturing method in which the forming die rolls while abutting, and the ears are peeled off by friction generated by the rotation in different directions, the work effort can be reduced and the work efficiency can be improved in the same manner as above. It is possible to sufficiently meet the demand for automation in this type of glove manufacturing method.

Further, in each of the above-mentioned manufacturing methods, if a molding die having a fluorine-based coating on the surface of the ear portion film-forming surface between the ridge portion and the base end edge is used, the above-mentioned fluorine-containing film is wetted. The slippery property improves the releasability when the ears that adhere to the mold surface are automatically peeled off by the ears removal belt, and reduces the amount of raw materials that form the ears that are originally unnecessary parts. The cost will be lower.
