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 step of performing a partial treatment is essential, and conventionally, there is no edge treatment (ear removal) device, and an operator successively cuts with a cutter or the like outside the production line. 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.

[0003]

However, even if the above-mentioned mold is used, as a result, the operator is not attached to the outside of the production line,
In addition, the work of peeling off the ears has to be done manually, and it cannot be said that the work effort has been improved sufficiently, and the work efficiency is poor and the entire manufacturing process is automated. There is also a background that there is a demand for improvement in this type of glove manufacturing apparatus.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to remove the ears of gloves formed on the surface of the mold by the dipping method. This is to automatically perform the process inside the machine, sufficiently contribute to the improvement of work labor and work efficiency, and sufficiently meet the demand for automation of the whole process in manufacturing this kind of gloves.

[0005]

Means for Solving the Problems The technical means of the present invention for achieving the above object are rotatably provided on a conveyor of an immersion molding line, and are immersed in a desired solution to form a film on the surface. The glove forming mold is moved while rotating it by forcibly rotating it in a predetermined direction around the axis, and the ear portion formed on the surface of the mold is removed by abutting it on the upper surface. And an ear removing belt, and the removing belt is rotated at a speed different from the rotational speed of the mold.

[0006] A glove mold, which is rotatably provided on a conveyor of an immersion molding line and has a surface formed by being dipped in a desired solution, is forcibly rotated in a predetermined direction around an axis. The removing belt is different from the rotating direction of the forming die, and the removing belt is different from the rotating direction of the forming die. It is to rotate in the direction.

EXAMPLE An example of the present invention will be described below. A glove forming mold 1 used in the manufacturing apparatus of the present invention has, for example, a mouth part 3 (hand entrance part) circumference of a mold body 2 formed in a hand shape. A glove main body film-forming surface 8 for forming a glove main body A from the tip 6 (pointed portion) to the fingertip portion 7 of the protruding portion 5 provided in the region with a pointed tip protruding projecting in a blade shape; Ridge tip 6 to base edge 4
Up to the ear portion film forming surface 9 on which the ear portion B is formed, and the mold 1 is rotatably attached to a support shaft 15 provided on an endless chain plate 13 provided in the manufacturing line, and After adjusting the mold 1 to a predetermined mold temperature, the whole mold is dipped once or plural times in a hanging vinyl chloride solution in a suspended state, and vinyl chloride paste is attached to the entire surface of the mold 1 and pulled up. And the protruding end 6
The paste is locally adhered in the form of a thin film due to the surface tension, and is semi-cured to form a film, and then moved to the automatic ear removal device 11.

The support shaft 15 provided on the chain plate 13 is configured to be rotatable in the w direction around the shaft center at a midway portion (rotational portion) 17 and is fixed on the chain plate 13. The glove forming mold 1 is axially attached to the holding portion 14 so as to be able to be laid sideways (y direction), supports the glove forming mold 1 by being connected to the tip thereof, and moves along the manufacturing line (z direction). That is,
The glove forming mold 1 formed by holding the film in the suspended state in the dipping step is supported by the main guide walls 24 provided on both sides of the chain plate 13 in the line direction in a standing state and moved, and the next ear In the removing step, the support shaft contact surface 26 faces upward, and the chain plate 13
With the sub-guide wall 25 arranged in parallel with
Support it in the state of lying down and move it.

Then, the glove forming mold 1 in the state of film formation on the surface which has moved to the automatic ear removing device 11 has the sub guide wall 25.
The support shaft 15 is laid sideways around the shaft attachment portion 16 of the support shaft 15, and the mold rotation transfer mechanism 1 of the automatic ear removal device 11 is arranged.
The ear part B is peeled off by the ear part removal belt 21 while being rolled counterclockwise by 2, and the process moves to the next surface treatment step and glove reverse peeling step. Further, the surface treatment process (that is, the dipping process → the surface treatment process → the ear removal process) may be performed before the ear removal process, and it can be appropriately changed. In the present embodiment, the glove forming mold 1 is described as rotating in the counterclockwise direction (x direction), but it may be rotated in the clockwise direction as long as it can be rotated only in a predetermined direction.

As described above, the ear part removing mechanism 11 is composed of the mold rotation transfer mechanism 12 and the ear part removal belt 21, and the mold rotation transfer mechanism 12 is centered on the shaft center at the middle part (rotation part) 17. The support shaft 15 configured to be rotatable,
Then, the pinion 18 integrally provided around the rotating portion 17 of the support shaft 15 and the rack 1 arranged below the pinion 18 in parallel with the chain plate 13.
9, the pinion 18 meshes with the rack 19 as the chain plate 13 moves, and the upper part 15a of the rotating part 17 is rotated counterclockwise. Therefore, the glove mold 1 is forced to rotate counterclockwise. It is transferred while being rotated (x direction in the figure).

Further, the support shaft 15 has a ridge 20 provided around the pinion 18 at a position higher than 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.

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

Further, as shown in the figure, 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 portion 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 part removal belt 21, and the ridge 20 provided around the support shaft 15 rides 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 made slower than the mold rotation speed contrary to the above 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 through 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.

Further, as in claim 2, the ear removing belt 21 is rotationally adjusted in a direction different from the rotating direction of the glove forming mold 1 (when the mold is counterclockwise as shown in the drawing, the belt is rotating clockwise). Then, the forming mold 1 is rolled while the ear portion B formed between the ridge portion 5 and the base end edge 4 of the mold 1 is brought into contact with the forming mold 1. Membrane ear B
Is peeled off due to the friction generated by the rotation of the two in different directions, and the edge can be treated in the same manner as above. 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.

In this embodiment, the ear mold is removed by placing the glove forming mold 1 on its side, 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 ear removing belt 21
The stripping scraps collection belt 30 is installed in the lower part of the line direction in order to collect the stripped-off ears B and effectively contribute to resource reuse.

Further, the glove forming mold 1 used in the present embodiment is only one embodiment and is not limited, but the surface of the ear portion film-forming surface 9 is provided with a fluorine-based coating film 10 of fluorine, silicon or the like. It may be provided. That is, the wettability (sliding property) of the above-mentioned fluorine can further improve the releasability when the ears B attached to the surface of the ears film forming surface 9 are automatically peeled off by the ears removal belt 21. At the same time, the amount of the vinyl chloride paste forming the ear B, which is an unnecessary portion, can be reduced, which is very practical and preferable.

By the way, a specific example of the above-mentioned fluorine-containing coating 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.

[0024]

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. It is a glove manufacturing device that rolls the mold while bringing the ears into contact with each other and scrapes off the ears by the friction caused by the difference in speed to process the edges. 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 meet fully the automation requirements in this type of glove making equipment.

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 in the case of the glove manufacturing apparatus that rolls the mold while abutting it, and scrapes off the ears by the friction generated by the rotation in the different directions to process the edges, the work effort can be reduced and the work efficiency can be improved. It is possible to sufficiently meet the automation request in this type of glove manufacturing apparatus.

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 and the base 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.
