Description

Refilling Machine {Pill forming Machine}

The present invention is a pair of forming rollers having a plurality of semi-circular grooves formed in the longitudinal direction on the outer circumference of the present invention to form a ring in a spherical shape of the dough inserted between the two forming rollers while reciprocating and rotating at the same time. More specifically to the ventilation, more specifically, the pair of forming rollers constitute a roller actuator to enable the reciprocating motion and the rotational movement at the same time, the bidirectional cylinder, the operating shaft inside the bidirectional cylinder (rotary bush) By being supported by a bush capable of rotation and linear movement as described above, to adjust the reciprocating speed and the stroke of the operating shaft to suit the size of the ring to be molded in the machine to improve the productivity of the machine.

The roller actuator installed in the conventional recirculation machine (ring molding machine) has been registered and registered by the applicant of the present application Patent No. 10-596738 (name of the invention: spherical molding apparatus), and Patent No. 10-663383 ( Name of the Invention: Included in the invention of the forming roller driving device of the annular molding machine.

The common structure of the roller actuator included in the conventional invention is that the rotating body of the pulley type is rotated by the rotational force of the motor, and the crank link between the eccentric position of the rotating body and the distal end of the rotating shaft in which the forming roller is installed By connecting and installing, the crank link was converted into a linear reciprocating motion of the rotating body so that the pair of forming rollers were reciprocated in a straight line.

As described above, the stroke distance that the forming roller reciprocates is the distance corresponding to twice the eccentric distance that the center of the rotating body and the crank link is hinged, the stroke distance is a fixed state.

However, when the ring is molded in the dehydrator, it is formed from a small diameter such as silver to a large diameter such as wowang cheongsim ring. Naturally long

If the circumferential length is short as described above, it is preferable to shorten the reciprocating distance of the forming roller, and if the length of the circumference is long, it is preferable to lengthen the stroke distance of the forming roller reciprocating. Both the forming of the small ring and the case of forming a ring with a very large diameter, such as the wohwang cheongsim-hwan, have the same irrational problem as the stroke distance that the forming roller reciprocates.

That is, when forming a ring with a small diameter such as silver, the circumferential length of the small ring (3 mm ring) is 9.42 mm (3.14 x 3 mm), so that the stroke distance of the forming roller is sufficient to provide a large ring (20 Since the circumferential length of the ring) is 62.82 mm in advance, the stroke length of the forming roller should be 63 mm.

As seen in such a situation, although the stroke distance of the forming roller is 10 mm when the small roller is formed, the stroke distance of the forming roller is 63 mm even when the small roller is formed in the conventional roller actuator 200. As the work is fixed, there is a problem that productivity is reduced because work space is generated by 53 mm.

In addition, according to the conventional roller actuator to change the rotational movement to a linear movement in the crank method, a large shock and vibration occurs when the crank link is reciprocated in a straight line in the portion eccentrically connected to the rotating body and the direction of movement is changed. Had together.

The operation of the present invention having the above-described structure will be described with reference to FIGS. 1 to 7. FIG.

The machine 100 according to the present invention has the same basic working relationship with the inventions of Patent Registration Nos. 10-596738 and 10-663383 registered and filed by the applicant of the present invention. It will be described in detail with respect to the roller actuator portion 200 which is the main part of the present invention.

That is, the basic working relationship of the recirculator 100 according to the present invention is extruded through the nozzle 5 in the form of noodle-doodles with a screw 4, the dough contained in the hopper 3, as shown in Figure 1 The dough to be extruded in the form is molded into a spherical shape by a pair of forming rollers 6 simultaneously performing a reciprocating motion and a rotational motion by a roller actuator 200 installed in the main body 1 of the feedback.

Then, as described above, the pair of forming rollers 6 rotate and reciprocate in a straight line so that the dough residues are buried in the semicircular grooves 6a of the forming rollers 6 in the process of forming a ring between the forming rollers 6 on both sides. In this case, as shown in FIGS. 1 and 5 and 6, as the brush 7 is rotated by the power of the motor 40, the dough residue on the forming roller 6 in contact with the brush 7 is removed. It is also the same as the conventional invention (Patent Registration No. 10-596738).

The following describes the working relationship related to the roller actuator 200 which is the main part of the present invention.

As shown in FIGS. 1, 2 and 5, when the drive gear 10 is rotated by the rotational force of the motor 9 installed inside (1), the spline 11 engaged with the drive gear 10 and its driving Another spline 11 engaged with the spline 11 meshed with the gear 10 is rotated in a reverse direction to each other, and both splines 11a for driving the cleaning tool which are individually engaged with the outside of both spline 11 are also engaged with each other. The gear 10 rotates in the reverse direction.

As shown in FIGS. 2, 3 and 6, first, as the two splines 11 for ring molding rotate in opposite directions to each other, the operating shaft of the bidirectional cylinder 20 in which the splines 11 are installed on the rear rod 22c ( 22) is rotated, the working shaft 22 is a rotational movement and a linear reciprocating motion at the same time according to the linear reciprocating motion of the bi-directional cylinder (20).

At this time, in the front rod (22b) installed in front of the two-way bidirectional cylinder 20, the forming rollers 6 are installed facing each other so that the noodle-dough dough extruded between the forming rollers 6 on both sides is a forming roller on both sides. The semicircular groove 6a of (6) is first cut by the width of the semicircular groove, and the dough pieces thus cut are spherically shaped as the pair of forming rollers 6 rotates back and forth. As these forming rollers 6 rotate downward, the ring formed between the two semicircular grooves is discharged downward.

As shown in FIG. 3 and FIG. 4, the operating shafts 22 rotating as described above are linearly reciprocated. As shown in FIG. 3 and FIG. 4, the two hydraulic inlets 21b formed in the cylinder operating spaces 23 on both sides of the piston 22a are provided. If the hydraulic pressure flows into the front hydraulic outlet 21b during the operation, the piston 22a is pushed backward in the cylinder operating space 23 and the hydraulic pressure filled in the rear cylinder operating space 23 becomes the rear hydraulic entrance 21b. The working shaft 22 is linearly moved backward while being discharged to the external hydraulic line through.

The operation shaft 22, which has been linearly moved backwards, stops the hydraulic supply to the front hydraulic entrance 21b according to the signal of the controller including the electromagnetic valve (not shown), and supplies the hydraulic pressure to the rear hydraulic entrance 21b. The shaft 22 moves linearly from the rear to the front, and the working shaft 22 reciprocates back and forth, which is the same as the known bidirectional cylinder.

The bidirectional cylinder 20 is provided with a ring-shaped partition 24 on the stepped portion 21a of the cylinder barrel 21, and a bush 25 is installed on the outside thereof, and a tightening nut 26 is tightened on the outside thereof. The cylinder operating space 23 is formed between the front and rear side ring-shaped partitions 24 and the piston 22a reciprocates in the cylinder working space 23.

As described above, in the cylinder barrel 21, the actuating shaft 22 simultaneously performs a linear reciprocating motion and a rotational motion. The front and rear rods 22b and 22c of the actuating shaft 22 can simultaneously perform a linear reciprocating motion and a rotational motion. Supported by the bush 25, the working shaft 22 is to enable the linear reciprocating motion and rotational movement at the same time.

The bush 25 shown in Fig. 7A shows an example in which the front and rear rods 22b and 22c simultaneously perform linear reciprocating and rotational movements. When a plurality of balls 25c are interposed between the rods 22b and 22c and the tube 25a is fixed, the front and rear rods 22b and 22c can simultaneously perform a linear reciprocating motion and a rotational motion.

The bidirectional cylinder 20 as described above can be freely controlled as a controller, the speed and stroke of the operation shaft 22 reciprocating forward and backward as in the known bidirectional cylinder when forming a ring with a small diameter, such as silver The stroke length of the working shaft 22 can be set short, and the stroke length of the working shaft 22 can be set long when molding a ring with a large diameter such as the right sulfur blue ring.

In the process of forming the ring by the roller actuator 200 including the two bidirectional cylinders 20, as shown in FIGS. 1 and 6, the brush 7 which is in contact with the lower side of the forming roller 6 is moved to a motor ( 40), and shake off the dough residue from the forming roller (6).

Or, the two-way cylinder 20 of the roller actuator 200 is provided with a two-way cylinder (20a) for cleaning the roller for scraping off the dough residue stuck in the semi-circular groove (6a) of the forming roller (6), this roller cleaning In the case of the bidirectional cylinder 20a, the roller shaft installed in the bidirectional cylinder 20a for cleaning the roller is operated in the same manner as the two bidirectional cylinders 20 for the ring molding, so that the linear reciprocating motion and the rotational motion are performed at the same time.

Then, a plurality of semi-circular gear parts inserted into the front rod 22b drawn forward of the roller cleaning bidirectional cylinder 20a corresponding to the semicircular groove 6a of the forming roller 6 as shown in FIGS. 2 and 6. A circular scraping plate 33 formed in the form of gears is installed at the outer circumference of the disc to scrape off the dough residues buried or pinched in the semicircular groove 6a of the forming roller 6 as the semicircular gear portion 32. .

The spline 11a provided on the rear rod 22c of the bidirectional cylinder 20a provided with the circular scratching plate 33 is engaged with the spline 11 provided behind the bidirectional cylinder 20 next to it.

Therefore, in the front side, the forming roller 6 and the circular scraping plate 33 rotate in the opposite direction with each other in a state where the gear is engaged, and the front rod 22b on the bidirectional cylinder 20 side and the bidirectional cylinder 20a side. The front rods 22b reciprocate in opposite directions, respectively, so that the dough residues buried or stuck in the semicircular grooves 6a of the forming roller 6 can be scraped off as the semicircular gear portions 32.

Thus, in the process of scraping off or pinching the dough dregs in the semi-circular groove 6a of the forming roller 6 as the semi-circle gear portion 32, the dough dregs have viscosity, so that they are buried in front and rear surfaces of the circular scratching plate 33. Will be gathered together.

At this time, the circular scratching plate 33 is the front and rear surfaces of the circular scratching plate 33 while passing through the slit grooves 36 of the comb plate 37 formed in the form of hair combs from the upper side to the lower side as shown in FIGS. Dough dregs 201 on the surface are removed while being scratched by the comb portion outside the slit groove 36.

The dough dregs 201 removed as described above are placed on the upper surface of the rain plate 37, and when the dough dregs 201 are stacked on the rain plate 37, the rain plate 37 is hinged outwardly as in "a". I will shake it off and use it.

The rain plate 37 is inserted into the bush 34 installed in the front plate 2 in a state where the slide plate 35 is fitted to the circular scratching plate 33 so that the front rod 22b of the bidirectional cylinder 20a is front and rear. Followed by the reciprocating movement in the process of forming a ring with a pair of forming roller (6) is to continue to remove the dough residue on the circular scraping plate 33 and to clean.
