DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to make the technical idea of the present invention clear. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a block diagram of a computer system according to an embodiment of the present invention; Fig. For convenience of explanation, the apparatus and method are described together when necessary.

FIG. 1 is a perspective view illustrating a configuration of a can seaming apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view of a can seaming apparatus according to an embodiment of the present invention.

The can seaming device 100 according to an embodiment of the present invention is a device for placing a can lid on the upper surface of a can body and then rolling the can body and the lid of the can to seal the can. 1, the can-seaming device 100 includes a bottom plate 20 constituting a bottom surface, supporting members 21a, 21b and 21c vertically standing on the bottom plate 20, and supporting members 21a 21b, and 21c of the roof plate 22 are joined together by a frame.

The bottom plate member 20 and the roof plate member 22 are connected to both ends of the support members 21a, 21b and 21c so that the bottom plate member 20 and the roof plate member 22 are supported by the support members 21a, 21b and 21c ) Of the length of the guide rail. In the bottom plate 20, a can elevating means 10 is mounted and fixed by raising a can body having a can lid at its upper portion.

In one embodiment, the upper portion of the can elevating means 10 may be provided with a seating portion 11 depressed on the upper surface. The seat portion 11 is recessed in a circular shape having the same diameter as the lower surface of the can to be placed thereon. With this configuration, the can body with the can lid placed thereon can be matched and seated on the seat portion 11. [

At the center of the can elevating means 10, elevating means for elevating and lowering according to the rotational motion is provided. For example, a configuration in which a female screw and a male screw are combined is provided inside a middle portion of the can elevating means 10, so that the lever 12 attached to the intermediate portion is horizontally rotated to rotate the intermediate portion, So that the upper end portion on which the can is mounted, that is, the seat portion 11, can be moved up and down together with the elevation of the intermediate portion. The configuration of the can elevating means 10 will be described in detail with reference to Fig.

For example, as shown in FIG. 1, when the lever 12 is positioned, before the seat 11 of the can elevating means 10 is elevated, the lever 12 is moved horizontally The lever 12 is moved through the guide groove 13 and moves up the seat portion 11 by the movement of the screws located at the intermediate portion of the can elevating means 10. [ The seaming chuck 40 located in the vertical direction of the seat portion 11 can be brought into contact with the upper surface of the can lid placed on the can body as the seat portion 11 is raised.

In another embodiment, the can elevating means 10 may include driving means for providing power to the elevating operation. In this case, the lever 12 can be omitted, and the can elevating means 10 can perform the elevating operation in accordance with the configuration like the switch.

As the can elevating means 10 performs the ascending operation, the can placed on the can elevates upward together. When the position of the can is maximized by the can elevating means 10 as shown in Fig. 2, The seaming chuck 40 is brought into contact with the upper surface of the can, that is, the can lid placed on the can. As a result, the can is sandwiched and fixed between the can elevating means 10 and the seaming chuck 40 located in the vertical direction of the can elevating means 10.

1 and 2, a decelerator 30 and a motor 35 are provided on a top surface of a roof plate 22 included in a can-seaming device 100 according to an embodiment of the present invention, 22 may be provided with an arm 50 to which a seaming chuck 40 and seaming rollers 60a, 60b are coupled.

The seaming chuck 40 is located at a vertical position opposite to the can elevating means 10 on the lower surface of the roofing plate 22. [ The seaming chuck (40) and the speed reducer (30) are connected to each other through the roof panel (22). The seaming chuck 40 can be rotated by the decelerator 30 provided with the rotational force from the motor 35. [

Conventional can-seaming devices transmit rotation power by a motor to a seaming chuck via a belt. In such a power transmission structure, the size of the can-seam device can not be miniaturized, and it has been necessary to use a motor having a considerably large horsepower. In view of such a problem, the can-seaming device 100 according to the present invention allows the motor 35 of a small horsepower to use the decelerator 30 to provide sufficient rotational force for can-seaming. Accordingly, the size and weight of the can-seaming device 100 can be reduced, and the can-be-seaming device 100 can be compactly used for home use.

The seaming chuck 40 can rotate the can lid on which the can lid is placed while rotating in accordance with the rotational power provided from the speed reducer 30. [ That is, the rotating seaming chuck 40 transmits the rotational force to the entire can while pressing the upper surface of the can lid ascended by the elevating operation of the can elevating means 10, and rotates the can together with the rotation thereof.

Thus, while the can body and the lid are rotating, the seaming rollers 60a and 60b approach the seaming chuck 40 and press the can lid and the can body together. The seaming rollers 60a and 60b are pressing means for pressing the rim of the can lid in the rotating operation according to the position of the arm 50 in rotation and sealing the rim of the can lid along the outer circumferential direction of the can.

The arm 50 according to an embodiment of the present invention has a Y-shape. A lever 70 is coupled to one end of Y-shaped terminals and seaming rollers 60a and 60b are attached to both ends of the Y- . The seaming rollers 60a and 60b are configured to sequentially approach the seaming chuck 40 by the horizontal rotational movement of the arm 50 in accordance with the horizontal movement of the lever 70 in one direction.

In one embodiment, the lever 70 can extend through an opening 23 through any of the posts that are supported by the support members 21a, 21b, and 21c so that the lever 70 It can be combined with the handle 75 for manual control.

The opening 23 can have a horizontally extending configuration and the horizontal operating range of the lever 70 can be determined according to the size of the opening 23 since the lever 70 moves horizontally through the opening 23 .

In one embodiment, a power switch 77 may be located at a portion adjacent to the handle 75. The power switch 77 can supply power for driving the motor 35 and the speed reducer 30. Therefore, the user can simultaneously control the rotational motion of the seaming chuck 40 while controlling the movement of the arm 50 with the handle 75. [ As shown in FIGS. 1 and 2, the power switch 77 can be variously formed at an easy position for manual control of the lever 70.

3 is a perspective view showing an arm and a seaming roller according to an embodiment of the present invention.

Referring to FIG. 3, the arm 50 has a Y-shape, and the first seaming roller 60a and the second seaming roller 60b having different configurations may be coupled to the other end of the arm 50. FIG.

The seaming rollers 60a and 60b can engage with the arm 50 through the pillars 61a and 61b. 8 and 9, the seaming rollers 60a and 60b according to the embodiment of the present invention may have pillars 61a and 61b formed at a portion thereof which is partially deviated from the center of the circular roller. That is, the seaming rollers 60a and 60b may have an eccentric structure.

In one embodiment, one of the opposite ends of the arm 50 is fixed with a first seaming roller 60a which presses the edge of the opening of the can and the curl of the can lid to fold, And a second seaming roller 60b for pressing the curled curl of the can lid to seal the rim of the curled can by the first seaming roller 60a is fixed.

In one embodiment, the arm 50 adjacent to the seaming rollers 60a, 60b may be provided with a vertical adjustment screw 90. The up-and-down adjusting screw 90 engages with the columns 61a and 61b of the seaming rollers 60a and 60b. Therefore, when the up-down adjusting screw 90 is rotated, the seaming rollers 60a and 60b can be finely adjusted up and down.

In order for the can lid and the can body to be completely sealed, the can lid must be completely in close contact with the can body, and at this time, the portions where the seaming rollers 60a and 60b are pressed against the can lid need to be finely adjusted. Therefore, in the present invention, since the arms 50 are provided with the vertical adjustment screws 90, the height of the seaming rollers 60a and 60b can be finely adjusted, so that the accurate height matching between the can lid and the seaming rollers 60a and 60b It becomes possible.

A first through hole 51 penetrating the arm 50 upward and downward is formed in the bent central portion of the arm 50. A fixing member 52 is inserted through the first through hole 51 to form a roof plate member 22 And the arm 50 are fixed. The arm 50 can rotate about the portion of the first through hole 51 coupled with the roof plate 22. [

The second through hole 71 may be formed at one end of the arm 50 to which the seaming rollers 60a and 60b are not coupled so as to be coupled with the lever 70. [ Accordingly, when the lever 70 is moved, the arm 50 coupled with the roof board 22 can be rotated.

The arm 50 according to an embodiment of the present invention rotates about a central portion coupled with the roof board 22 in accordance with the horizontal movement of the lever 70 in one direction. The seaming rollers 60a and 60b can be configured to apply pressure to the can lid rotating sequentially with the seaming chuck 40 by the arm rotating in accordance with the horizontal movement of the lever 70. [ Since the seaming rollers 60a and 60b rotating about the central portion are brought close to the seaming chuck 40 sequentially within a predefined range as the lever 70 is moved horizontally, The can lid and the can body can be completely sealed.

The radius of rotation about the first through hole 51 is determined by the length of the opposite ends of the arm 50 to which the first and second seam rollers 60a and 60b are coupled and the length of the seaming rollers 60a and 60b ) ≪ / RTI > Specifically, the first arm length da corresponding to the length of the other end of the arm 50 to which the first seaming roller 60a is coupled, the diameter of the first seaming roller 60a, and the diameter of the second seaming roller 60a The second arm length db corresponding to the length of the other end of the arm 50 to which the second seaming roller 60b is coupled and the distance between the second seaming roller 60b and the seaming chuck 40, The applied pressure can be determined.

According to the embodiment, the first arm length da and the second arm length db may be substantially the same. That is, as the arm 50 is rotated by the fixing member 52, the radii by the arm lengths da and db can be the same.

4 to 6 are bottom views of the roof board 22 of the can-seam device 100 according to an embodiment of the present invention. FIG. 7 is a view showing cross sections of the cans in order to explain different seaming operations according to the seaming rollers 60a and 60b according to an embodiment of the present invention.

4 to 6, a can seaming apparatus 100 according to an embodiment of the present invention includes a shingling chuck 40, an arm 50, a fixing member 52, (60a, 60b), and an elastic body (80).

The seaming rollers 60a and 60b engage with the arm 50 to perform a seaming operation of the can through a horizontal rotational movement. The Y-shaped arm (50) is fixed to the lower surface of the roofing plate (22) by a fixing member (52). The Y-shaped arm 50 fixed to the roof plate 22 can be horizontally rotated about the fixing member 52 as a center axis.

4 to 6, when the user moves the lever 70 coupled to one end of the Y-shaped arm 50 in one direction, the arm 50 rotates, One end of the Y-shaped arm 50 to which the first seaming roller 60a is coupled and the other end of the Y-shaped arm 50 to which the second seaming roller 60b is coupled, The ends are sequentially close to each other.

Referring to Fig. 4, the first seaming roller 60a is close to the seaming chuck 40. Fig. At this time, the center of the first seaming roller 60a is located on the line between the center of the fixing member 52 and the center of the seaming chuck 40, and the first seaming roller 60a is located at the center of the seaming chuck 40 Close. The distance rs between the center of the fixing member 52 and the center of the seaming chuck 40 is fixed so that the first arm length da of Fig. 3, the diameter rl1 of the first seaming roller 60a, The pressure applied to the lid of the can may vary depending on the diameter rc. As described above, since the first seaming roller 60a can have an eccentric structure, the pressure applied to the lid of the can can be adjusted by controlling the diameter rl1 of the first seaming roller 60a.

The first seaming roller 60a can apply pressure to the can lid by being in proximity to the seaming chuck 40 in the same shape as the cross section shown in Fig. 7 (a). As shown in Fig. 4, when the first seaming roller 60a comes into contact with the rim of the rotating can, the first seaming roller 60a presses the rim of the rotating can lid and the can, The rim is folded and rolled. For example, the first seaming roller 60a has a J-shaped portion having a narrow width and a deep depth at which the edge of the can is pressed, so that the edges of the can and the lid are wound along the J-shape.

In FIG. 7, the distance between the seaming chuck 40 and the first seaming roller 60a is indicated by 'd1'. This distance is the distance between the inner radius of the seaming chuck 40 and the outer radius of the first seaming roller 60a and may correspond to the distance between the can body and the lid of the can. 'D1' can be adjusted when moving the eccentricity of the first seaming roller 60a. Therefore, in the present invention, by adjusting the diameter of the first seaming roller 60a as well as the fixing member 52, the seaming chuck 40, and the first arm length da, the pressure applied between the can body and the lid Can be adjusted.

The user continuously moves the lever 70 in the same direction after moving the lever 70 in one direction so that the first seaming roller 60a approaches the seaming chuck 40. [ 5, the first seaming roller 60a moves away from the seaming chuck 40 and a line connecting the center of the seaming chuck 40 and the fixing member 52 passes through the first seaming roller 60a and the second seaming roller 60a, And is positioned between the rollers 60b.

The second seaming roller 60b comes close to the seaming chuck 40 and the center line of the fixing member 52 and the seaming chuck 40 The center of the second seaming roller 60b is positioned.

The distance between the center of the fixing member 52 and the center of the seaming chuck 40 is fixed in the same manner as described with reference to Figure 4 so that the second arm length db in Figure 3, Depending on the diameter rl2 and the diameter of the seaming chuck rc, the pressure applied to the can lid can be different. As described above, the second seaming roller 60b can also have an eccentric structure, so that the pressure applied to the lid of the can can be adjusted by controlling the diameter rl2 of the second seaming roller 60b.

When the second seaming roller 60b comes close to the seaming chuck 40 as much as possible, the second seaming roller 60b is pressed against the edge of the dried can by the first seaming roller 60a as shown in Fig. 7 (b) . When the rim of the rounded can is pressed by the first seaming roller 60a, the rim of the dried can is squashed and the can is sealed. For example, the second seaming roller 60b has an L-shaped portion having a wide width and a shallow depth at a portion where the rim of the can is pressed, and the rim of the can wrapped by the first seaming roller 60a and the lid It can be pressed flat.

In one embodiment, the distance 'd2' between the second seaming roller 60b and the seaming chuck 40 may be less than 'd1'. That is, since the can lid is completely sealed by the second seaming roller 60b, the can lid and the can body can be further compressed. Similarly, 'd2' can be adjusted through the eccentric structure of the second seaming roller 60b.

4 to 6, the user merely moves the lever 70 horizontally, but does not adjust the force applied to the can. The pressure applied to the can in the canning apparatus 100 according to the present invention depends on the diameter rc of the seaming chuck, the diameters rl1 and rl2 of the respective seaming rollers 60a and 60b, Lt; RTI ID = 0.0 > 52 < / RTI > Therefore, even if the can-seaming operation is performed manually, the can-seaming accuracy is not changed depending on the operator, and uniform can-seaming operation becomes possible.

As shown in FIG. 6, the case where the second seaming roller 60b is close to the seaming chuck 40 corresponds to the case where the lever 70 has moved to the maximum. The movement radius of the lever 70 can be limited by the opening 23 formed in the column plate described with reference to Fig. In another embodiment, the movement radius of the lever 70 may be determined by the elastic limit of the elastic body 80 and the restoring force.

When the seaming rollers 60a and 60b are manually operated to adjust the levers 70 to perform the pressing operation of the seaming rollers 60a and 60b, the seaming rollers 60a and 60b are excessively caught by the seaming chuck 40, The can can be collapsed and the can is not sealed when the seaming rollers 60a and 60b are located too far from the seaming chuck 40. [

For this reason, it is important to appropriately control the distance and pressure between the seaming rollers 60a and 60b and the seaming chuck 40. Accordingly, in the present invention, as the arm 50 rotates through the fixing member 52, 60a, and 60b are closest to the seaming chuck 40. [0051] As shown in FIG. The distance when the distance between the seaming chuck 40 and the seaming rollers 60a and 60b is the closest is made constant so that the same pressing force is applied to the can lid as the lever 70 moves.

According to the embodiment, the two seaming rollers 60a and 60b may be located on one side of the seaming chute 40 when the arm 50 of the canning seamer 100 does not proceed with the can seaming operation. Considering the position between the seaming chuck 40 and the seaming rollers 60a and 60b, the lever 70 may be elongated at an angle rather than in a straight line.

According to the embodiment, when the arm 50 of the can-seaming device 100 has a Y-shape, the arm 50 is rotated about the fixing member 52, and when the rotation radius comes into contact with the seaming chuck 40, It can be understood that the operation is performed. However, when the first arm length da and the second arm length db are different from each other and the first seaming roller 60a is driven by the seaming chuck 60a depending on the diameters of the first seaming roller 60a and the second seaming roller 60b 40 and the rotation radius of the second seaming roller 60b in contact with the seaming chuck 40 may be different from each other. Further, in another embodiment, the turning radius may be different depending on the angle formed by each end of the arm 50 extending from the center portion (i.e., the center where the first through-hole 51 is formed).

8 is a cross-sectional view of a portion of a can seaming device according to an embodiment of the present invention. More specifically, FIG. 8 shows a cross section from the seaming chuck 40 to the Y-shaped arm 50 when the seaming chuck 40 and the first seaming roller 60a are closest to each other.

8, the Y-shaped arm 50 is fixed to the roof plate 22 through a fixing member 52 inserted in the first through hole 51 and rotates. The first seaming roller 60a can be coupled to the arm 50 with an eccentric structure. The first seaming roller 60a is coupled with the arm 50 in an eccentric structure via the column 61a so that the diameter rl1 reaching the seaming chuck 40 as shown in Fig. ) In the direction of the fixing member 52 may be different from each other. In this case, depending on the distance from the seaming chuck 40, the pressure applied to the rim of the can, including the can lid, varies differently. Therefore, depending on the direction in which the eccentric structure of the first seaming roller 60a is positioned, Can be different.

When the diameter of the can lid rim is smaller than the diameter of the rim of the lid of the can, the first seaming roller 60a is arranged on the side of the seaming chute 40 ). ≪ / RTI > Therefore, after the first seaming roller 60a is fixed to the arm 50 at an eccentric position deviated to one side from the center, the first seaming roller 60a can be rotated to adjust the close distance to the seaming chuck 40 have.

The horizontal distance between the first seaming roller 60a and the seaming chuck 40 and precisely the edge of the can lid rotated by the seaming chuck 40 can be adjusted by providing the eccentric post 61a, The vertical distance between the pressing portion of the first seaming roller 60a and the edge of the can lid can be adjusted through the adjustment of the vertical adjustment screw 90 as described above.

Fig. 9 is a view for explaining the positional relationship between the seaming roller engaged with the arm and the vertical adjustment screw.

9, the column 61a of the first seaming roller 60a is formed with a concave portion 62a, and can engage with the convex portion 92 of the up-down adjusting screw 90. As shown in FIG.

When the vertical adjustment screw 90 moves up and down in the concave-convex coupling state, the recess of the column 61a moves along the convex portion 92, so that the first seaming roller 60a can be moved up and down finely. When the first seaming roller 60a is moved up and down, the vertical position of the recessed groove portion (the J-shaped groove portion or the L-shaped groove portion in FIG. 7) in which the first seaming roller 60a abuts the can lid is adjusted, More perfect matching becomes possible and sealing becomes easy.

8 and 9 show that the concave portion is located on the column 61a of the first seaming roller 60a and the convex portion is located on the up and down adjusting screw 90 and the first seaming roller 60a, The shape of the concavo-convex coupling can be changed, for example, the convex portion is located on the column 61a of the upper and lower adjusting screw 90 and the concave portion is located on the upper and lower adjusting screw 90. [

Although the first seaming roller 60a has been described with reference to Figs. 8 and 9, the second seaming roller 60b may have the same structure.

As described above, the can seaming apparatus according to the present invention is configured such that the Y-shaped arm 50 rotates as the lever 70 moves in one direction, so that the first and second seaming rollers 60a and 60b So as to sequentially approach the rim of the can lid. Especially, the accuracy of the can sealing can be improved by controlling the distance when the first and second seaming rollers 60a and 60b are closest to the seaming chuck 40 within the predefined range.

Accordingly, the seaming operation for the can lid is completed by manual operation in one direction, and the pressure applied to the can lid can be adjusted to be constant even in the case of manual operation. Furthermore, there are provided components for finely adjusting the vertical and horizontal distance between the can lid and the seaming rollers, so that the pressing portion can perfectly match the edge of the can lid.

10 is an exploded perspective view of the can elevating means according to an embodiment of the present invention.

10, the can elevating means 10 includes a guide portion 101 having a guide groove 13, a lever portion 102 having a lever 12, a screw structure (not shown) inside the lever portion 102, A ring-shaped fixing part 104, and a seat part 11, as shown in Fig.

When the lever 12 is rotated along the guide portion 101, the cylindrical portion 103 moves in the screw portion of the lever portion 102 and the seat portion 11 moves up or down. As the lever 12 moves along the guide groove 13, the can body and the lid of the can move up and down. In order for the whole can to make contact with the seaming chuck 40 and rotate, Needs to be finely adjusted.

Therefore, it is possible to adjust the height at which the can ascend and descend by adjusting the screw of the cylindrical portion 103 separately from the adjustment of the lever 12. That is, as the screw of the cylindrical portion 103 is finely adjusted, the coupling height between the lever portion 102 and the cylindrical portion 103 is adjusted, and as a result, the elevation height of the can can be finely adjusted.
