率に限度があつた。 In general, in hot working methods such as warm working methods and vacuum pressure working methods, continuous processing methods are generally used. However, in such a processing method, waiting and movement are intermittent, and a processing method that maintains true continuity is not currently available. In other words, in the present invention, a molding object such as a straw is kept on standby for a certain period of time, and a certain degree of continuity is maintained by molding with a mold that moves one-dimensionally. However, due to the necessity of keeping the molded object on standby for a certain period of time, the processing machine cannot maintain complete continuity, and the waiting time causes time loss, which limits efficiency.

動することは困難である。 Furthermore, when the object to be formed is in the form of a sheet, it is relatively easy to hold, feed, and move the object to be formed, but as in the present invention, the object to be formed is, for example, a rod-shaped object, especially a synthetic resin. When molding the end portion of a manufactured straw, it is difficult to hold, feed, and move the straw, which is the workpiece.

とを目的とするものである。 The present invention has been made in view of the above-mentioned circumstances, and is a processing method for molding the tips of synthetic resin straws, which are placed at regular intervals on the belt of a belt conveyor. , for a straw to be processed that is fixed and transferred in a fixed direction with respect to the direction of travel, from a cavity whose inside has the shape to be formed into which the straw is inserted in order to simultaneously process multiple straws to be processed. It is possible to move a plurality of workpieces each having a large number of molds arranged side by side in a direction parallel to the conveyor and in a direction perpendicular to the conveyor at the same speed as the conveyor transfer speed. By moving the member, each straw to be processed is inserted into the cavity of the mold, and the workpiece is moved together with the straw, during which time the tip of the straw is formed, and then the workpiece is moved in the direction perpendicular to the conveyor, and the workpiece is inserted into the cavity of the mold. It is an object of the present invention to provide a method for processing a continuous portion of a synthetic resin straw tip in which the tips of a large number of straws to be processed can be processed simultaneously by moving the straws further apart.

るので成形加工に支障が生じることはない。 The detailed contents of the continuous processing method of the present invention will be explained below based on the illustrated embodiments. FIG. 1 shows a synthetic resin straw that is an object to be processed. As shown in the figure, this straw has a socket-shaped portion 1a formed at one end of a small-diameter straw 1, and a case in which this socket-shaped portion 1a is formed by the processing method of the present invention will be described. FIG. 2 shows a mold 2 used in carrying out the processing method of the present invention, which is made by combining a plurality of molds 3 for forming the socket portion 1a of the straw 1 shown in FIG. That is, each mold 3 has a cavity into which the straw 1 is inserted, and also forms a socket-shaped portion 1a. Although FIG. 3 only shows one workpiece (mold 2), even if a plurality of molds 2, which are workpieces having a plurality of molds 3, are provided, individual molds A plurality of 3 may be provided. Even if a plurality of straws are provided in this manner, the straws on the conveyor are arranged and transferred at intervals, so that no problem occurs in the molding process.

工する側に並びに配置されている。 FIG. 3 is a diagram showing the configuration of the processing method of the present invention. In this figure, reference numeral 5 denotes a synthetic resin straw, which is an object to be processed, and is fixedly arranged on, for example, a conveyor 4 at a constant interval, and is moved in the direction of arrow A at a constant speed. Reference numeral 2 denotes the molds having the structure as shown in FIG. 2, which have already been described, and are arranged side by side on the side of the conveyor 4 where the straws 5 are to be processed.

をコンベアーに固定しておくことが望ましい。 The mold 2 is moved in the direction of arrow B, which is the same direction as the moving direction A of the conveyor, at the same speed as the moving speed of the conveyor, and simultaneously moved in the direction of arrow C. In other words, the mold 2 moves in a direction that is a combination of movement in the direction of arrow B at the same speed as the conveyor and movement in the direction of arrow C at an arbitrary speed.
Due to such movement of the mold, the mold 2 remains aligned with the plurality of straws 5 within the range indicated by reference numeral 6 in FIG. While moving in the direction of arrow C, that is, in the direction approaching the straw 5. As a result, each straw 5 within the range 6 is brought into close contact with each mold 3 without stopping its movement. In this case, it is desirable to provide a stopper member on the conveyor to prevent the straws 5 from shifting. In this way, each straw 5 and each mold 3
are in close contact with each other for a certain period of time (a certain distance)
During this movement, one end of each straw 5 is formed into a socket shape as shown in FIG. 1. When molding is completed, the mold 2 moves at the same speed in the direction of arrow B and simultaneously moves in the opposite direction to arrow C, that is, performs a movement that is a combination of movement in the direction of arrow B and movement in the opposite direction to arrow C, Move away from straw 5. At this time, in order to prevent the straw from adhering to the mold and moving in a direction away from the conveyor, it is desirable to provide a suitable holding member to fix the straw to the conveyor.

場合矢印Ｃと反内方向へは移動させないで矢印Ｂ

成した移動にしてもよい。 In this way, the mold 2 is moved along the conveyor in the direction opposite to the arrow B in order to be circulated on a track at a certain distance from the straw. In this case, arrow B should not be moved in the direction opposite to arrow C.
It may also be moved linearly in the opposite direction to arrow B.
The movement in the opposite direction and the movement in the opposite direction to arrow C may be combined.

ロー５と密着するととになる。 In this way, one cycle of movement of the mold 2 is completed, and the movement is then repeated again. Here, the mold 2 is moved in the direction of arrow B at the same speed as the conveyor 4, but in this case, the mold 2 is moved at the same speed along with the plurality of straws 5 in the part indicated by 7, and each mold is moved at the same speed as the conveyor 4. When the mold 3 comes into close contact with each straw 5 within the range 7, it becomes .
以上のような動作を繰り返し行なえば複数本ず

なしに成形されて行く。 By repeating the above-described operations, a plurality of straws 5 (in the example shown in FIG. 3, ranges indicated by reference numerals 6 and 7) are successively formed without stopping their movement.

率を向上し得る。 As described above, according to the continuous processing method of the present invention, by moving the workpiece two-dimensionally, for example, even if the workpiece has an individual shape, it can be processed into a plurality of workpieces while being moved. It is possible to process anything while maintaining complete continuity without stopping each step, and it can be processed extremely efficiently. Furthermore, efficiency can be further improved by arranging a plurality of workpieces each having a large number of molds.
