On the other hand, the present invention relates to a tube rotation device of an injection molding machine in the above-described tube manufacturing apparatus, particularly with respect to the rotation aligning portion 300. However, since the tube loading process is required before rotational alignment, this portion will be described first.

As shown in FIG. 2, the tube loading unit 100 of the tube manufacturing apparatus of the present invention includes a tube receiving tube 110 for receiving a tubular body TB extruded in a cylindrical shape, A plurality of tubular bodies (TB), preferably four tubular bodies (TB), which are supplied through the tube feeder 120 A tube conveying unit 140 for receiving a plurality of tube bodies TB aligned through the tube aligning unit 130 and transferring the tubes to a specific position; And a turntable mount 150 for transferring the tube body TB transferred through the tube spout forming part 140 to the turntable T (see FIG. 1) for transferring and aligning the tube body T B to the tube spout forming part 200.

4, the tube feeder 120 is a plate-shaped member for guiding the tube body TB received in the tube receiving tube 110 to the tube aligning unit 130 to smoothly supply the tube body .

A tube guide plate 122 is installed on both sides of the surface of the tube feeder 120 so as to be spaced apart from each other. 122, i.e., an adjusting rod 126 for adjusting the distance.

Therefore, by adjusting the gap adjusting member 124 according to the length of the tube body TB, the tube body TB is guided to roll down smoothly without being twisted or tilted when the tube body TB rolls down.

Therefore, the tube feeder 120 must be arranged at an angle.

In addition, when the tube body TB is rolled down and caught on one side of the tube feeder 120, it is instantaneously detected and stopped to stop the tubing body TB from being caught or stopped A detection sensor 128 may be further provided.

In this case, the detection sensor 128 may be a proximity sensor or a photosensor.

3 to 5, the tube aligning unit 130 includes a plurality of tubular bodies TB, which are held in the tube bodies TB one by one and are rotated counterclockwise so as to set a plurality, preferably four, Which is shown in FIG. 4, is inverted 180 degrees so that the driving relationship can be clearly expressed, unlike FIGS.

The tube seating part 132a is provided in a block shape having a substantially V-shaped groove so that the rolled tube body TB can be stably installed.

At this time, a release preventing piece 132b is installed on one side of the tube seating base 132a so as to extend upward.

The release preventing piece 132b is a kind of stopper for preventing the tube body TB that is seated on the tube seating base 132a from rolling down due to the inertia generated when the tube seating base 132a rotates.

In addition, the tube seating base 132b may be further provided with a support piece SP and a fastening binding piece CP at a lower portion thereof in order to increase the rotational fluidity, for example, as shown in FIG.

The tube seat 132a is fixed on the chain 132c and the chain 132c is wound around the driving sprocket 132d and the driven sprocket 132e to rotate in an endless track shape. Is designed so as to protrude from the lower end of the tube feeder 120 and rotate in the opposite direction.

As the tube seat 132 is lifted up, the tube body TB is received by the tube body 132. At this time, the release body 132B can smoothly and stably prevent the tube body TB from rolling down, Is guided to the tube seat 132a so as to be seated.

The drive sprocket 132d and the driven sprocket 132e are spaced apart from each other by a distance and the sprockets are fixed to the drive shaft 132f and the driven shaft 132g. The coaxial shaft 132g is rotatably fixed to the pair of support plates 134a.

A drive box 134b is installed on one side of the support plate 134a. A drive timing pulley 134c rotatably driven by a drive motor M (see FIG. 5) is installed in the drive box 134b. And the driven timing pulley 134d and the driven timing pulley 134d are connected by a timing belt 134e wound in an endless track form and the driven timing pulley 134d and the driven timing pulley 134d One end of the drive shaft 132f passes through the support plate 134a and then is fixed to the center of the drive shaft 132f so that the drive shaft 132f automatically rotates when the driven timing pulley 134d rotates, The drive sprocket 132d rotates.

The driving motor M is fixedly installed between a pair of the support plates 134a.

In addition, a sensor installation bar 136a is fixed to the inner surface of one of the pair of the support plates 134a, and a plurality of proximity sensors 136b are provided at a predetermined interval in the sensor installation bar 136a, Four proximity sensors 136b are provided.

6, a connecting piece 138a is connected and fixed to the lower end of the supporting plate 134a, a fixing piece 138b is fixed to the lower portion of the connecting piece 138a with a gap therebetween, and the fixing piece 138b A screw cylinder 138c is fixed to the center of the screw 138d and a ball screw 138d which is threaded through the screw cylinder 138c is assembled. The tip of the ball screw 138d is connected to the lower end surface A pair of guide rods 138e fixed to the lower end surface of the connecting piece 138a at one end and passing through the fixing piece 138b at opposite ends of the ball screw 138d, Respectively.

A handle 138f is fixed to the lower end of the ball screw 138d.

Therefore, when the handle 138f is rotated, the ball screw 138d is rotated, and the height of the support plate 134a can be adjusted while the connection piece 138a is moved away from or close to the fixing piece 138b .

The reason why the height of the support plate 134a needs to be adjusted is that the tube body TB has a large diameter or a small diameter because the height of the tube transport unit 140 is fixed, In order to align the height of the tube aligning unit 130 with the height of the tube conveying unit 140 according to the diameter of the tube aligning unit 130. In this case,

That is, the center of the circle of the tube body TB is aligned with the center of the circle of the insertion rod 144 (see FIG. 2), which will be described later, constituting the tube alignment unit 130.

In other words, since the tube aligning unit 130 has a structure in which the tubular body TB moves left and right for transporting the tube body TB, the height adjustment is relatively difficult, while the support plate 134a is not moved left and right, Since it is much easier to construct the structure so as to move it up and down, the height of the support plate 134a is controlled in the present invention.

2, a plunger PU is provided on the outer side of the support plate 134a opposite to the tube transfer unit 140, and one end of the plunger PU is connected to the plunger block PB are fixed to the mast block PS and both ends of the mast block PS are fixed to the mast block PM and the lower end of the mast block PB is fixed to the mast (Not shown).

When the tube body TB is aligned on the tube aligning unit 130, the pusher cylinder PU is driven to push the pusher PU toward the tube conveyer unit 140. At this time, The tube body TB is moved from the tube aligning unit 130 to the tube conveying unit 140 while being pushed together with the tube body TB.

A cutter CUT is provided between the tube aligning unit 130 and the tube conveying unit 140 so that the tube body TB moved to the tube conveying unit 140 is moved downward by a predetermined length .

At this time, the length cutting can be accurately performed by controlling the cutting position to be determined according to the moving distance of the pushing unit (PU).

The tube conveying unit 140 is slidably fitted in a pair of guide bars GR and one end of the guide bar GR is connected and fixed by a connecting bracket BR in the form of a piece, The bracket BR is installed upright in the form of a vertical plate and has a conveying rod CR passing through the connecting bracket BR and having one end fixed to the tube conveying unit 140 and the other end connected to the conveying cylinder CY do.

A vertical plate 142 is fixed to a side surface of the tube conveying unit 140 where the cutter CUT is provided and a plurality of vertical plates 142 projecting toward the tube aligning unit 130 And an insertion rod 144 is provided.

Here, the insertion rod 144 is disposed at a position that can coincide with the center of the circle of the tube body TB.

The turntable 140 is disposed at an end of the guide bar GR at a distance from the tube aligning unit 130 in a direction orthogonal to the guide bar GR.

The turntable mount 150 is provided with a tube accommodating table 152 in a direction in which the tube transporting unit 140 is viewed and an unillustrated mounting cylinder is provided below the turntable mount 150, And is configured to cause the mounting unit 150 to move back and forth.

The turntable T is provided with a plurality of, preferably four, pairs of tube fixing members TP at intervals of 90 DEG as shown in FIG. 1, and rotates by 90 degrees under the control of a controller (not shown) .

The present invention having such a configuration has the following operational relationship.

The tube bodies TB housed in the tube receiving tube 110 are rolled down along the tube feeder 120 and are sequentially placed on the tube seating base 132a.

For example, when four tube bodies (TB) are seated one by one on the tube seating base 132a, they are arranged in the form as shown in FIG.

At this time, the proximity sensor 136b accurately detects the position of the tube bodies TB, and when the detection is defective, a warning is issued to inform the operator that the proximity sensor 136b can confirm the position of the tube body TB.

When the four tube bodies TB are moved toward the tube conveying unit 140, the driving motor M is driven in accordance with the control sequence to rotate the tube seating base 132a in the form of an endless track, The tube body is aligned in the same manner and put in the waiting state for return.

When the tube body TB is thus aligned, the transporting cylinder CY is operated in accordance with the control sequence, and the tube transporting unit 140 is disposed at a position facing the tube aligning unit 130.

Then, the center of the insertion rod 144 and the center of the tube body TB are automatically aligned with each other.

Here, the centering must be set in advance by operating the handle 138f in accordance with the diameter of the tube body TB.

In this state, the pushrod cylinder (not shown) operates to push the pushrod PU toward the tube transport unit 140.

The push rod PU pushes the tube body TB toward the insertion rod 144 of the tube conveying unit 140. As a result,

The tube body TB is inserted into the insertion rod 144 and then the cutter CUT is lowered to cut the tube body TB to a predetermined length and cut the cutter CUT to the home position Is returned.

This process controls the depth of insertion of the tube body TB into the insertion rod 144 by adjusting the movement distance of the push rod cylinder (not shown) while the controller recognizes the processing length of the tube body TB Or the length of the remaining extra portion may be cut off while the tube body (TB) is fully inserted.

When the tube body TB is completely moved to the tube conveying unit 140 through this process, the pushing cylinder (not shown) also returns to the home position.

Then, the transfer cylinder CY is operated to push the tube transfer unit 140.

The tube transport unit 140 moves along the guide bar GR while fixing the tube body TB to the insertion rod 144 and stops at a point orthogonal to the turntable mount 150. [

This is configured to be automatically set by adjusting the stroke of the transfer cylinder CY.

Thus, when the tube body TB is positioned in front of the turntable mount 150, the turntable mount 150 advances to accommodate the tube body TB in the tube accommodating chamber 152. When the tube body TB is retracted The tube body TB is detached from the insertion rod 144.

When the tube body TB is separated from the insertion rod 144 through this process, the tube conveying unit 140 is again moved to the tube aligning unit 130 side along the control sequence, and the tube aligning unit 130 is moved The turntable mount 150 advances through the empty space.

The tube body TB accommodated in the tube accommodating table 152 is then transferred from the tube accommodating table 152 to the turntable T while being inserted into the tube fixing member TP of the turntable T, The turntable mount 150 is retracted to return to the home position.

Then, the turntable T is rotated by 90 degrees to dispose the open end of the tube body TB toward the tube spout forming part 200.

The tube spout forming unit 200 is formed by molding a tube spout TS having the shape shown in Fig. 3 at the open end of the tube body TB by using synthetic resin. Then, the turntable T is rotated 90 ° to cut the pointed tip of the tube spout TS and rotate the turntable T again through 90 ° to seal the open hole of the cut tube spout TS with a tin foil and then with the foil It is heat treated and firmly presses the silver foil to fix it completely.

When the above process is performed, the tube body TB has a structure in which one end thereof is opened and the other end thereof is formed of a tube spout (TS) and closed with a tin foil, and continuous processing is possible in one apparatus.

In order to assemble the tube cap TC into the tube spout TS formed in this way, the tube cap coupling part 500 must be transferred to the tube cap coupling part 500 provided separately, TC) are separately molded and separately supplied, so that it is difficult to configure them as a single device, and thus, it is provided separately from the tube loading and tube spout molding machine.

Therefore, a means for transporting the tube body TB from the point away from the turntable T to the tube cap coupling part 500 is required, which is a tube rotating device according to the present invention.

8 and 9, the tube rotation device according to the present invention refers to the rotation alignment part 300 and is spaced apart from the tube cap coupling part 500 with the transport platform 310 interposed therebetween.
