Description

[Detailed Description of the Invention] Conventionally, in this type of automatic machine for producing dip-molded products such as patterned gloves, only the patterning process for the first layer thin film attached to the mold was performed by hand-shaping the patterned seal. was.

The present invention aims to save labor, reduce costs, standardize products, and eliminate defective products by automating the patterning process. A mechanical part that immerses resin latex, plastisol or organosol and pulls it out to attach the first layer thin film to the mold surface, and a mechanical part that gels the first layer thin film by heating, and the same mold as above or a mechanical part that immerses it in a different synthetic resin latex, plastisol or organosol again and pulls it up to attach a second thin film to the surface of the first thin film; a mechanical part that gels the second thin film by heating; Patterned gloves, etc. formed by a molded product removal section that inverts and peels the first and second layer thin films from the mold, and a chain drive that circulates the mold by passing through each of these parts in the order listed above. In an automatic dip molded product manufacturing machine, the machine part that gels the first layer thin film to the second
A first reciprocating table which advances a predetermined distance and retreats at high speed in synchronization with the advancement of the mold is installed below the path of the mold that advances toward the machine part for depositing the thin film. Immediately after the reciprocating table starts moving forward, the U-shaped actuating member approaches the mold from the side and attaches a transfer tape, which will be described later, to the mold, leaving residual heat. A tape tensioning device presses the outer surface of the layer thin film at a predetermined position in a stretched state and also retreats just before stopping forward movement to eliminate the pressure bonding, and at the same time as the tape tensioning device, an arcuate actuating member approaches from the opposite side. A holding device that comes into contact with the mold and also retreats to release the contact and assist the above-mentioned crimping from behind, and a holding device that supports the above-mentioned crimping from behind, and a holding device that is attached to the transfer pattern between the tip of the U-shaped actuating member and the mold. 1. A transfer tape feeding device that continuously feeds the heating and pressurized transfer tape in an intermittent feeding state that stops immediately before the forward movement of the reciprocating table starts, and a U-shaped actuating member that transfers the transfer tape to the first layer thin film. The gist is that each roller is equipped with a rotating roller that rotates while the tape is being pressed and presses the area on which the transferred pattern is attached on the transfer tape.

Since the present invention has the above-mentioned configuration, the process of patterning the first layer thin film attached to the mold can be carried out fully automatically and unattended, which has the effect of completely achieving the intended purpose. This method not only has favorable effects, but also has favorable effects such as not having to temporarily stop the mold during the process.

Hereinafter, an embodiment of the present invention will be described. A mechanical part that immerses a mold in transparent synthetic resin latex, plastisol, or organosol and pulls it out to adhere the first layer thin film 3 to the mold surface; 3, a mechanical part that is gelled by heating;
a mechanical part that immerses the same mold again in the same or different synthetic resin latex, plastisol or organosol as above and pulls it out to adhere a second thin film 3' on the surface of the first thin film; and a second thin film. 3' to gel by heating, a molded product take-out part to invert and peel these first and second layer thin films 3, 3' from the mold, and molding by passing through these parts in the order listed above. An automatic manufacturing machine for dip-formed gloves formed by a chain drive that circulates the mold, etc. (The overall structure is not shown, but a flowchart of the product obtained by this is shown in Figure 2.)
At this time, the mold is placed below the passage of the mold A, which advances from the machine part that gels the first layer thin film to the machine part that attaches the second layer thin film (in the direction indicated by the arrow in the figure). A first reciprocating table 1 moves forward by a predetermined distance (shorter than the distance between the molds) and retreats at high speed in synchronization with the advance of the molds A, and above the first reciprocating table 1 Immediately after starting the forward movement, the U-shaped actuating member 2 approaches the mold A from the side and attaches a transfer tape 10, which will be described later, to the mold A, thereby depositing a predetermined portion of the first layer thin film 3 in which residual heat remains. A tape tensioning device 5 driven by a cylinder 4, which is crimped to the outer surface of the position in an extended state and retracted just before the forward movement stop to eliminate the crimping; A holding device 8 driven by a cylinder 7, in which the actuating member 6 approaches from the opposite side and comes into contact with the mold A, and also moves away to release the contact and assist the above-mentioned crimping from behind, and a place 9 where the transferred pattern 12 is attached.
Transfer tape feed that continuously supplies the heated and pressurized transfer tape 10 between the tip of the U-shaped actuating member 2 and the mold A in an intermittent feed state that stops immediately before the first reciprocating table 1 starts moving forward. While the transfer tape 10 is being pressed against the first layer thin film 3, the U-shaped actuating member 2 has a screw bolt drive device 22 (partially shown) and a chain drive device 11. It is equipped with rotating rollers 13 that are rotated and moved by a device 23 (partly shown) and a spring extrusion device 24 (partly shown) to press the transfer pattern 12 adhering location 9 of the transfer tape 11. .
