型にしなければならない。(Prior art) When moving a large number of flasks in a row on a roller conveyor in a molding line, pouring line, etc., the last flask is pushed by a pusher consisting of a pneumatic or hydraulic cylinder. is a known technique. (For example, Japanese Patent Publication No. 46-37270) By the way, when moving a large number of heavy flasks (hereinafter referred to as a flask group), a large pressing force is required before the flask group in a stationary state starts to move. However, once it starts moving, a relatively small pressing force is sufficient. However, conventional flask pushers use general cylinders, and the pressing force is the same from beginning to end.
Once the flasks begin to move, more pressing force than necessary is exerted, and energy is wasted accordingly. Also, since a large pressing force is applied to the moving flask group, the conveyance speed of the flask group increases, and the leading edge of the flask collides with the stopper with great force, so the cushion cylinder of the stopper absorbs this impact. It must be large enough to withstand it.

ことができるように設計されている。 The length of the piston rod 9 of the main cylinder 2 is larger than that of the piston rod 6 of the auxiliary cylinder 3, and a pusher head 11 is attached to the leading end thereof. The main cylinder 2 and the auxiliary cylinder 3 have ventilation holes 12, 13,
14 and 15 and are connected to a compressed air source (not shown) through conduits (not shown), respectively;
The main cylinder 2 alone does not have enough pressing force to move the group of flasks 17 that are stationary on a roller conveyor 16, which will be described later, and only when the pressing force of the auxiliary cylinder 3 is added, can the group of flasks 17 move. It is designed to be able to move. However, once the group of flasks 17 starts moving, it is designed so that the group of flasks 17 can be continued to be pushed only by the pressing force of the main cylinder 2.

述べたのと同じ工程がくり返されるものである。(Function) In the flask transport conveyor constructed as described above and in the state shown in FIG. When it is supplied to the auxiliary cylinder 3 through the main cylinder 2 and the piston rod 6 of the auxiliary cylinder 3, respectively, the piston rod 9 of the main cylinder 2 and the piston rod 6 of the auxiliary cylinder 3 are extended, and the pusher head 11 moves forward and comes into contact with the flask 17 on the carry-in conveyor 18. . The flask 17 is pushed by the pusher head 11, moves slightly to the right, and comes into contact with the flask 17 located at the left end of the group of flasks 17 on the roller conveyor 16. At this point, the pusher head 11 is about to move forward further, but the main cylinder 2
does not have enough pressing force to move the flasks 17 which are in a stationary state, the pusher head 11 stops moving forward, and accordingly the piston 8 of the main cylinder 2 also stops moving. However, the auxiliary cylinder 3
As the piston rod 6 continues to move forward, the tip of the rod 6 eventually comes into contact with the back surface of the piston 8 of the main cylinder 2. At this time, the pushing force of the pusher head 11 is the sum of the pushing force of the main cylinder 2 and the pushing force of the auxiliary cylinder 3, which exceeds the frictional resistance of the flasks 17, so that the pusher head 11 The frame 17 group can be pushed and moved. By the way, since the piston rod 6 of the auxiliary cylinder 3 is shorter than the piston rod 9 of the main cylinder 2, when the pusher head 11 moves forward a predetermined distance, the auxiliary cylinder 3
The rod 6 reaches its extension limit and stops, and as a result,
The pressing force of the pusher head 11 becomes only the pressing force of the main cylinder 2 again. However, at this time, the group of flasks 17 has started to move and the frictional resistance thereof has become small, so that the group of flasks 17 can be continued to be pushed only by the pressing force of the main cylinder 2.
When the rod 9 of the main cylinder 2 reaches its extension limit, the conveyance of one flask of the group of flasks 17 is completed. At this point, the piston rods 9 and 6 of both cylinders 2 and 3 are retracted, and a new flask 17 is carried to the outside of the left end of the roller conveyor 16 by the flask carry-in conveyor 18. Thereafter, the same process described above is repeated.

る。(Effects of the Invention) As is clear from the above description, the present invention has a flask pusher cylinder that pushes out a large number of flasks placed in a row on a roller conveyor, which consists of a main cylinder and an auxiliary cylinder. The cylinder is configured as a two-stage cylinder, and while the pusher head is moving forward a predetermined distance, the pressing force of the head is the sum of the pressing forces of both cylinders, and after the pusher head has moved forward the predetermined distance, the pressing force of the head is the sum of the pressing forces of the two cylinders. The pressing force is made to be only that of the main cylinder.

る。 Therefore, according to the present invention, the flask pusher exerts a large pressing force when moving a stationary flask group, but once the flask group starts moving, the flask pusher exerts a large pressing force to maintain that movement. Moreover, since only a sufficient and relatively small pressing force is exerted, no energy is wasted. In addition, since the pressing force applied to the moving flask group becomes smaller, the conveyance speed of the flask group becomes slower, and the impact when the most advanced flask collides with the stopper is also reduced, so that the shoe of the stopper becomes smaller. The cylinder can be made smaller.
なお実施例では空圧式シリンダを用いている
が、本考案は油圧式シリンダを用いる場合にも適
用可能なことは勿論である。 Although a pneumatic cylinder is used in the embodiment, it goes without saying that the present invention can also be applied to a case where a hydraulic cylinder is used.
