Description

A device for manufacturing aluminum container

The present invention relates to an aluminum container manufacturing apparatus, and more particularly, to an aluminum container manufacturing apparatus in which an aluminum plate wound on a roll is continuously supplied to a press, and a container formed by the press is automatically unloaded and loaded.

A container is a generic term for a container in which an article or packaged article can be placed, and the container also includes a plate-shaped tray without a lid made of a relatively rigid material such as paper, pulp, plastic, or thin aluminum plate.

Among them, an aluminum container made of a thin aluminum plate is light, easy to process, has excellent corrosion resistance, and is widely used in that it can be recycled.

In general, an aluminum container manufacturing apparatus is configured to include a feeder roller that pulls the wound aluminum plate and supplies it to a press, a press that press-forms the aluminum plate supplied from the feeder roller, and a conveyor that transports the aluminum container molded by the press. .

However, in the conventional aluminum container manufacturing apparatus, since the width of the feeder roller for supplying the plate material at the front end of the press is wider than the width of the plate material, the pressure of the feeder roller was applied over the entire width direction of the plate material.

If the left and right thicknesses of the plate material are different, or the axes of the upper and lower rollers constituting the feeder roller are not parallel, the pressure of the feeder rollers acted differently on the left and right sides of the plate material. There was a problem in that the meandering phenomenon that gradually moves occurs frequently. When a meandering phenomenon occurred, the process was inevitably disrupted, such as stopping the work and resetting the position of the plate between the lower roller and the upper roller before starting operation.

In addition, in the conventional apparatus, since the conveyor for collecting the finished product by the press and moving it to the stacker is composed of a simple belt, there is an inconvenience of separately separating foreign substances falling on the conveyor together with the container at a later time.

If it is determined that the description of the known technology in relation to the present invention may obscure the gist of the present invention, a detailed description of the known technology will be omitted.

It is a perspective view showing the state of the plate material wound through the uncoiler and the feeder included in the aluminum container manufacturing apparatus of 1, and FIG. 6 is an enlarged view showing the plate material coming out of the upper supply roller and the lower supply roller in FIG. 7 is a view showing the degree of occurrence of a meandering phenomenon of the plate in comparison with the conventional one, and FIG. 8 is a plan view of a conveyor part included in the apparatus for manufacturing an aluminum container of FIG. 1 .

1, the aluminum container manufacturing apparatus according to the first embodiment of the present invention is an apparatus in which an aluminum plate wound on a roll is continuously supplied to a press, and a container formed by the press is automatically unloaded and loaded, and an uncoiler 100 , a feeder 200 , a press 300 , a conveyor 400 and a stacker 450 .

The uncoiler 100 is configured to unwind the aluminum plate material (s) wound in the form of a coil at a constant speed.

The uncoiler 100 is a first plate material supply roller ( 120), the plate material washing tank 130 and the plate material (s) in which the washing liquid is placed between the plate mounting supply roller 110 and the first plate material supply roller 120 is immersed in the plate material washing bath 130 in the plate material (s) A washing tank roller 140 that applies tension is provided.

As shown in FIG. 2, the plate material-mounted supply roller 110 is rotated by the first rotational power unit 114, and its central axis 112 is rotated in the transverse direction (on the drawing) with respect to the supply direction of the plate material (s). It is configured to enable position adjustment in the left and right direction). This can be achieved by the guide member 152, the guide rail 153, and the handle 156 constituting the LM guide-ball screw structure.

As shown in FIG. 3 , the first plate material supply roller 120 is a first upper plate material supply roller 122 , a first lower plate material supply roller 124 configured to rotate in close contact up and down, and a rotational power to any one of them. and a second rotational power unit 126 for providing

As shown in FIG. 1 , the feeder 200 is configured to draw the plate material s released from the uncoiler 100 in a twin roll manner and introduce it to the press 300 side.

As shown in FIG. 4, the feeder 200 is an upper supply roller 210 and a lower supply that are installed side by side to pull the plate material s in the direction of entry of the press 300 into which the plate material s enters. A second rotational power unit 230 for providing rotational power to one of the roller 220 and the two rollers is provided.

Of these, the upper supply roller 210 has a length shorter than the width of the plate material (s) and is composed of a first diameter and is in contact with the central portion of the plate material (s). It is divided into a pair of non-contact sections 212 extending from both sides to a second diameter smaller than the first diameter.

As shown in FIG. 1 , the press 300 is configured to receive the plate material s from the feeder 200 and press-molded it into a container shape.

The conveyor 400 is configured to receive and convey the container (c), which has been molded by the press 300, by wind power. Since the container c made of an aluminum material is light and has a large area, it may be transferred to the conveyor 400 by a wind turbine (not shown) provided on one side of the press 300 .

The stacker 450 is configured in the form of a storage shelf on which the containers (c) transported from the conveyor 400 are dropped and loaded.

In this embodiment configured as described above, as shown in FIG. 5 , the plate material s unwound at a constant speed in the uncoiler 100 is pulled by the feeder 200 and introduced into the press 300 side. The press operation is carried out continuously.

In this process, in this embodiment, as shown in FIG. 6 , in proportion to the length of the contact section 211 of the upper feed roller 210 , the contact area between the upper feed roller 210 and the plate material s is reduced. , the meandering phenomenon of the plate material (s) (the phenomenon in which the plate material gradually moves toward the higher pressure because the pressure of the roller acts differently on the left and right sides of the plate material) is primarily reduced.

Conventionally, as shown in Figure 7 (a), the width of the roller width of the feeder for supplying the plate material (s) at the front end of the press is configured to be wider than the width of the plate material, over the entire width direction of the plate material (s) The pressure of the roller was applied. For this reason, when the left and right thicknesses of the plate material (s) are different, or when the axes of the upper and lower rollers constituting the feeder are not parallel, the pressure of the feeder rollers acted differently on the left and right sides of the plate material. There was a problem that occurred frequently. When a meandering phenomenon occurred, the process was inevitably disrupted, such as stopping the work and resetting the position of the plate between the lower roller and the upper roller before starting operation.

In contrast, in the present invention, as shown in (b) of FIG. 7 , only the contact section 211 in the middle of the upper supply roller 210 is in contact with the plate material (s), and is configured not to be in contact with the others, so that the contact It is possible to obtain the effect of lowering the degree of the meandering phenomenon of the plate that is generated in proportion to the area.

In particular, in the present invention, the conveying direction (depth direction in the drawing) of the plate material (s) is maintained by the non-deformed both sides area (A2) in non-contact with a pair of non-contact sections 212 among the entire area of the plate material (s). By being guided, it is possible to obtain the effect that the meandering phenomenon of the plate material (s) is reduced secondary.

On the other hand, in the conventional aluminum container manufacturing apparatus, since the conveyor that collects the finished product by the press and moves it to the stacker is composed of a simple belt, the foreign substances falling on the conveyor together with the container and introduced into the stacker must be separated later. There was discomfort.

As a countermeasure against this, in the present embodiment, the conveyor 400 is configured as a mesh conveyor as shown in FIG. 8 . That is, the conveyor belt 410 that transports the container c toward the stacker 450 while rotating in the form of an endless track is not a general rubber belt, but a wire mesh structure in which a plurality of wires 412 form a grid at regular intervals. do.

Therefore, according to the present invention, foreign substances that have flown in with the container after the press operation are dropped and separated through the space between the wires, and only the container is loaded on the stacker, thereby omitting the operation of separating foreign substances from the stacker later. have.

Hereinafter, an apparatus for manufacturing an aluminum container according to a second embodiment of the present invention will be described. Configurations overlapping with the previous embodiment are given the same reference numerals, and descriptions thereof are omitted.

9 is a longitudinal sectional view showing a plurality of bearing members included in the apparatus for manufacturing an aluminum container according to a second embodiment of the present invention, and FIG. 10 is for explaining the principle that the rotational speed of the plurality of bearing members of FIG. 9 is reduced It is a drawing, and FIG. 11 is a front view showing the operation state of the plurality of bearing members of FIG.

9, in this embodiment, the contact section 211 of the upper supply roller 210 is defined by a plurality of bearing members 270 coupled in a line along the rotation shaft 210a of the upper supply roller 210. do.

The bearing member 270 includes an inner ring 271 coupled to the rotation shaft 210a of the upper supply roller 210 and an outer ring 272 disposed on the outer periphery of the inner ring 271, as shown in FIG. ), a plurality of balls 273 interposed to freely rotate between the inner ring 271 and the outer ring 272 to mediate rolling contact, and a contact pad 274 made of urethane material coupled to surround the outer periphery of the outer ring 272 ), a friction wheel 275 protruding from one side of the inner ring 271 and bending and extending in a 'L' shape toward the outer ring 272, and a friction wheel 275 protruding from one side of the outer ring 272 toward the friction wheel 275 The support protrusion 276, the elastic member 277 coupled to the support protrusion 276 to face the extended end of the friction wheel 275 as an elastic body, and the elastic member 277 to be close to the extended end of the friction wheel 275 ) and a centrifugal member 278 for reducing the rotational speed of the outer ring 272 while selectively contacting the extended end of the friction wheel 275 according to centrifugal force.

When the rotation speed of the outer ring 272 is relatively slow, as shown in (a) of FIG. 10 , a small centrifugal force acts on the centrifugal member 278 . Accordingly, the centrifugal member 278 does not contact the friction wheel 275 or the degree of friction is decreased, and the rotation of the outer ring 272 is not prevented.

Conversely, if the rotational speed of the outer ring 272 is relatively fast, as shown in FIG. ), it interferes with the rotation of the outer ring 272 . As the rotational speed of the outer ring 272 increases, the centrifugal force also increases and the degree to which the rotation of the outer ring 272 is obstructed increases.

For example, as shown in FIG. 11, when the thickness of the plate material s passing between the upper supply roller 210 and the lower supply roller 220 is in the width direction, the left side is thick and the right side is thin, the bearing member ( The bearing member 270a on the left side of the 270) quickly pulls the plate material s in a state in which it is firmly in close contact with the plate material s, and the bearing member 270b on the right side is in a state of loosely contacting the plate material s. The plate material (s) is pulled slowly. This means that the left bearing member 270a rotates slightly faster than the right bearing member 270b.

As the rotation speed of the bearing member 270a on the left side is relatively high, as the centrifugal force acting on the centrifugal member 278 is large, the rotation speed is reduced while being prevented from rotating. As the rotation speed of the bearing member 270b on the right side is relatively low, the centrifugal force acting on the centrifugal member 278 is small, so that the rotation speed is not decelerated without being hindered in rotation.

Accordingly, the speed at which the left bearing member 270a pulls the plate material s becomes slow, and the speed at which the right bearing member 270b pulls the plate material s is maintained as it is. The rotational speed of the fast-drawn side is artificially slowed down.

As such, in the present invention, the rotational speed of a plurality of bearing members is uniformly controlled as a whole regardless of the difference in the thickness of the left and right of the plate, so that the meandering phenomenon caused by the difference in the thickness of the left and right of the plate is more stably suppressed.

Hereinafter, an apparatus for manufacturing an aluminum container according to a third embodiment of the present invention will be described. Configurations overlapping with the previous embodiment are given the same reference numerals, and descriptions thereof are omitted.

Referring to FIG. 12 , a conveyor driving unit 500 providing rotational power to the conveyor 400 is further included.

As shown in FIG. 13 , the conveyor driving unit 500 includes a driving motor 510 , a driving wheel 520 , a support bearing (not shown), a cap member 540 , a one-way clutch 550 , a driven wheel 560 and Consists of an interlocking rod (570).

Referring to FIG. 14 , the driving motor 510 is a motor having a rotational driving shaft 511 .

The driving wheel 520 is inserted and fixed to the rotational driving shaft 511 and the driving eccentric shaft 521 is provided with a first radius on the outside. The driving wheel 520 is coupled to the rotational driving shaft 511 through a key (not shown), and a fixing block is inserted into the outer groove of the driving wheel 520 so that the driving wheel 520 does not come off the rotational driving shaft 511 and fixed with a bolt. do.

The support bearing 530 is a bearing that rotatably supports the drive shaft 420 of the conveyor 400 .

The cap member 540 has a drive shaft 420 extending further from the support bearing 530 is inserted and fixed, and a head 541 extending outward is formed.

The roller 553 is accommodated, and the spring 555 is fixed to the spring seating part 554 formed by digging one side of the recess 552 to press the variable roller 553, but the recess 552 is the spring seating part ( 554), and the bottom becomes inclined.

Therefore, when the one-way clutch 550 is rotated in one direction, the variable roller 553 in rolling contact with the cap member 540 is pushed in the reverse direction, and is pressed up and down between the groove 552 and the cap member 540 to be the variable roller. 553 stops to transmit the rotational force to the cap member 540 .

Conversely, when the one-way clutch 550 is rotated in the other direction, since the variable roller 553 moves in the forward direction and rotates itself, the rotational force is not transmitted to the cap member 540, and the one-way clutch 550 rotates idle.

As shown in FIG. 14 , the driven wheel 560 is fixedly coupled to the outer periphery of the one-way clutch 550 and a driven eccentric shaft 561 is provided on the outside with a second radius wider than the first radius.

The one-way clutch 550 and the driven wheel 560 are coupled through a key, and a pair of snap rings 565 are fitted into the ring-shaped grooves on both sides of the inner circumferential surface of the driven wheel 560, so that the one-way clutch 550 is fixed. it is preferable

Both ends of the interlocking rod 570 are hinged to the driving eccentric shaft 521 and the driven eccentric shaft 561 via a ball bearing and a hinge bolt, respectively.

13, when the driving wheel 520 is continuously rotated by the rotation of the driving motor 510, the driven wheel 560 reciprocates at a predetermined angle, and the driven wheel When the one-way clutch 550 interlocked with 560 is rotated in one direction, it transmits a rotational force to the cap member 540 and the drive shaft 420, and when rotated in the other direction, the one-way clutch 550 is idle, In this process, the conveyor 400 repeatedly goes and stands at a certain period.

As such, in the present invention, the conveyor is configured to be driven intermittently, thereby obtaining the effect of further promoting the separation of foreign substances that have flown in with the container.

In the aluminum container manufacturing apparatus of the present invention configured as described above, only the contact section in the middle of the upper supply roller is in contact with the plate, and other sections are not in contact, so that the meandering phenomenon of the plate is generated in proportion to the contact area. It is possible to obtain the effect of lowering the degree.

In addition, the present invention can obtain the effect that the meandering phenomenon of the plate material is reduced secondary by guiding the conveying direction of the plate material by the non-deformed both side regions in non-contact with a pair of non-contact sections among the entire area of the plate material.

In addition, the present invention has the effect of omitting the work of separating foreign substances from the stacker later by dropping and separating the foreign substances that have flown in with the container after the press operation, and only the container is loaded on the stacker through the space between the wires. have.
