The present invention relates to a molding machine for forming a head in a tube, and more particularly, a series of insert-molding a head from an insertion of a tube material, cutting a head nipple to form an outlet in the molded head, and discharging the formed tube. It relates to a tube head molding machine that can automatically perform the process of improving the work productivity.

Generally, the container 1, such as the ileal container or the toothpaste container, is mounted on the tube 2 and the one end of which the contents are filled, as shown in FIG. It consists of a head (3) having a discharge port so as to, the lower outer surface of the tube (2) is formed on the outer surface of the tube marking portion (M) as a reference during the printing operation.

The tube (2) is composed of a hollow park cylinder or a hollow park cylinder, depending on the type of container, the length may be different from each other, the label or the phrase may be printed on the outer surface.

Accordingly, the conventional tube head molding machine is a device for integrally forming the head 3 at one end of the tube 2, and the operation of forming the head in the conventional tube 2 is performed by an operator individually by forming a flower rod on a rotating plate. After inserting one by one, the head molding machine installed on the upper side is lowered by the operator's operation, and when the molding is completed after a certain time, the head molding machine is raised again according to the operator's operation.

Continuously, the operator removes the molding in which the head 3 is formed at one end of the tube from the mounting rod of the rotary plate, and then transports it to a separate cutting device to form an outlet by cutting the tip of the head formed by injection molding, which is a post-processing operation. To cut the tip of the head was performed separately.

As described above, since the work of forming the head at one end of the conventional tube is performed by the manual labor of the operator, it takes a lot of time and has a problem of decreasing work productivity.

In addition, if the material length of the tube (2) is different from each other, the risk of defects in forming the head (3) by matching the injection mold to one end of the tube during head molding is very high, the cause of increasing the product defect rate It became.

And, if the tube (2) is provided in a hollow cylinder or hollow oval shape, and the printing is completed on the outer surface, the tube (2) inserted into the rack rod is molded with the head 3 has a predetermined direction set in advance Since it should always be inserted to have a constant orientation as possible, the operator checks the marking portion (M) with the naked eye to insert the tube (2) into the rod to ensure that the marking portion (M) is always constantly There was a problem that was cumbersome and time consuming.

In addition, there is another problem that the printing injection portion (not shown) formed at the other end of the tube (2) in a separate process in order to print on the outer surface of the tube (2).

Accordingly, the present invention has been proposed to solve the above conventional problems, the object of which is to insert-molding the head from the insertion of the tube, to cut the head of the head to form the outlet in the molded head, It is to provide a tube head molding machine that can automatically improve the productivity of the production process by automatically discharging the tube.

In addition, another object of the present invention is to arrange the tube before injection molding to have a constant orientation with respect to the marking portion, and to remove the unnecessary injection molding formed on one end of the tube and at the same time maintaining the length of the tube to maintain a constant head It is an object of the present invention to provide a tube head molding machine which can further improve the workability of forming a tube.

Meanwhile, as shown in FIGS. 1, 5, 9, and 10, the material discharging unit 170 divides the tube material T whose stem is cut from the second processing unit 160 by the split rotation unit 140b. It is disposed in the vicinity of the divided rotating portion 140b with a space of 90 degrees with the second processing unit 160 so that it can be separated and discharged.

The material discharging unit 170 is pivotally operated to clamp the head 3 formed on the tube material T, and includes a plurality of clampers 171 having a return elastic body 171b, and the other end of the clamper 171. Clamping cylinder 173 for forward and backward operation of the operating member 172 in contact with the connecting member, a connecting table 174 connected to the hollow body 174a to which the operating member 172 is slidably assembled, and the clamper ( And a discharge cylinder 175 for horizontally moving the connecting table 174 to separate and discharge the tube material T clamped at 171 from the split rotation part 140b.

Accordingly, the actuating member 172, which is advanced along with the rod during the forward actuation of the clamping cylinder 173, interferes with the rear end of the clamper 171, and the clamper 171 is centered around the pin member 171a. By turning the tip portion of the downward downward, the head 3 of the tube material (T) located inside the clamper 171 is to be clamped by the clamper 171.

In this state, when the discharge cylinder 175 is forward-actuated, the tube material (T) clamped to the clamper 171 to the split rotation unit 140b together with the connecting rod 174, the hollow body 174a. Since it is moved in the direction away from the rotor, it is separated from the second insertion rod 146 of the divided rotation part 140b.

In addition, in the inner space of the clamper 171, the fitting hole 176 inserted into and fixed to the head 3 of the tube material T, and the elasticity of the elastic body 171b when the back of the operating member 172 is returned. A striking member 177 striking the head 3 fixed to the fitting hole 177 by the restoring force and a bushing member 178 for guiding forward and backward movement of the striking member 177 are configured.

Accordingly, after the tube material T is completely separated from the second insertion rod 146 and the operation of the discharge cylinder 175 is reversed, the elasticity of the elastic body 171b of which the restraining force is released is completed. As the rear end of the clamper 171 is turned downward by the restoring force, the striking member 177 is hit and the tip is advanced through the bushing member 178.

In this case, by strongly hitting the head (3) fixed to the fitting hole 177 of the striking member 177 to completely separate the tube material (T) fixed to the fitting hole 176 tube material (T) All work to shape and manufacture the head 3 is completed.

Meanwhile, the third feeder 120c of the material feeder 120, the first rotating part 130a and the first cutout 130b of the first processing part 130, and the material input part 140a of the material supply part 140. ) Is provided on the first base (B1), the divided rotation part 140b, the molding unit 150, the second processing unit 160 and the separate discharge unit 170 of the material supply unit 140 is the second base It is provided on (B2).

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to clarify that knowledge is easy to know.

According to the present invention as described above, before the injection molding a plurality of tubes are moved to the insertion rod and inserted into the insert rod, the head is inserted into the injection molding, the head head is cut to form an outlet in the head formed in the tube after injection molding In addition, by automatically performing a series of processes for discharging the molded tube can be significantly improved work productivity compared to the conventional.

In addition, by detecting the marking portion formed on the tube before injection molding, the tube is inserted and arranged to have a constant orientation, and the unnecessary injection molding portion formed at one end of the tube is removed and the forming length of the tube is made uniform. Regardless of the shape and length, the effect of stably performing the work of forming the head into the tube is obtained.
