In addition, as shown in Fig. 2 (a), each registration roller 10 has the rotating shaft 11 extended in the horizontal direction, can rotate centered by this rotating shaft 11.In addition, although use 6 registration rollers 10 to be illustrated in present embodiment, this quantity is not limited to.In addition, in present embodiment, being illustrated by registration roller 10, but being not limited thereto as location division, also can be the component slided relative to lid component 62.And, as the component slided relative to lid component 62, as shown in Fig. 2 (b), be preferably used in and become gradually thin conical by its shape portion 12 (12a, 12b) etc. on the direction of lid component 62.This is because, gradually thin conical by its shape portion 12 etc. is become according to such, when lid component 62 is placed in the assigned position of horizontal direction, even if some offsets lid component 62 a little in the horizontal direction, also this lid component 62 can be guided in the horizontal direction assigned position (assigned position can be pulled into).
In addition, in present embodiment, use being described the form of welding between the peripheral ends of mould component 61 and the peripheral ends of lid component 62 by laser L hereinafter, but being not limited thereto, such as, also can be make electricity consumption, combustion gas, ultrasonic wave etc. apply energy to engage.But, when using laser L, (pin point) heats welding position with can aiming at small objects, therefore can prevent from applying unnecessary heat to internals 63 grade, and then the change of properties of internals 63 can be prevented, so be preferred.
As shown in Figure 1, equipment for closing cans possesses: below rotating part 45b, supports maintaining part 20 from below and can rotate; And top rotating part 45a, (during from top view) can rotate with the direction identical with the direction that below rotating part 45b rotates.In addition, the below of below rotating part 45b is provided with the lifting unit 50 making the movement in the vertical direction of rotating part 45b below this, by this lifting unit 50, below rotating part 45b is moved upward, thus mould component 61 and lid component 62 is lifted upward.
In addition, as shown in Figure 1, the dynamic up and down portion 91 of laser irradiating part 30, each registration roller 10, below rotating part 45b, top rotating part 45a and backoff portion described later 90 is linked with the control part 80 controlling them.And, this control part 80 controls, make before the laser L by laser irradiating part 30 welds mould component 61 and lid component 62, whole registration roller 10 is placed in retreating position (present embodiment is top position) (with reference to Fig. 5 (a)-(c)).
In addition, as shown in Fig. 2 (a), (b), upper and lower location division 40 is provided with make registration roller 10 in the vertical direction movement carry out the backoff portion 90 of keeping out of the way.This backoff portion 90 has: dynamic portion 91 up and down, has to be arranged at upper and lower location division 40 and relative to this upper and lower location division 40 retractile axle 91a in the vertical direction; And linking part 94, be linked to this and move the axle 91a in portion 91 up and down and be linked to supporting member 43.And this linking part 94 has the horizontal direction extension 92 extended in the horizontal direction, and be arranged at the end of horizontal direction extension 92 and the above-below direction extension 93 extended in the vertical direction.In addition, the axle 91a in dynamic portion 91 is linked to the approximate centre in dynamic portion 91 up and down up and down.In addition, above-below direction extension 93 extends in the bullport 49 being arranged at upper and lower location division 40 in the mode extended in the vertical direction, and the movement of horizontal direction is restricted.And, the axle 91a in dynamic portion 91 extends in the vertical direction relative to upper and lower location division 40 up and down, thus registration roller 10 is placed in retreating position (present embodiment is top position), the axle 91a in dynamic portion 91 shrinks in the vertical direction relative to upper and lower location division 40 up and down, thus registration roller 10 is placed in lower position.
In addition, the below of top rotating part 45a is provided with rotating part 45a rotation above this and the location division up and down 40 be fixed in the vertical direction.In addition, this upper and lower location division 40 is provided with temporary fixed pin (abutting part) 41, before carrying out the location of the horizontal direction of lid component 62 by registration roller 10, is connected to lid component 62 from top.This temporary fixed pin 41 is freedom of movement (with reference to Fig. 4) in the vertical direction.
In addition, registration roller 10 arranges 2 on the long limit of lid component 62 and mould component 61, and minor face arranges 1.Wherein, the registration roller 10b on the one side on long limit (left side of Fig. 2 (a) and Fig. 3) is arranged on supporting member 43 via the force application component 42 of spring etc., and the registration roller 10a of the another side (right side of Fig. 2 (a) and Fig. 3) on long limit is fixed on supporting member 43.On the other hand, the registration roller 10b of (downside of Fig. 3) of minor face is arranged on supporting member 43 via the force application component 42 of spring etc., and the registration roller 10a of the another side (upside of Fig. 3) of minor face is fixed on supporting member 43.Therefore, with the one side on long limit and minor face while 3 the registration roller 10b abutted can move in the horizontal direction while accepting the active force from force application component 42,3 the registration roller 10a abutted with the another side on long limit and the another side of minor face fix in the horizontal direction.In addition, be arranged on registration roller 10b on supporting member 43 in the end face of lid component 62 side via force application component 42, and the interval of the registration roller 10a be fixed on supporting member 43 between the end face of lid component 62 side is preferably the interval also slightly less than the size (width) of the horizontal direction of the lid component 62 envisioned.About this point, also can be that the end face of registration roller 10b in lid component 62 side and the interval of registration roller 10a between the end face of lid component 62 side can be adjusted by not shown interval guiding mechanism.
In addition, as shown in Fig. 2 (b), when conical by its shape portion 12 is used as location division, the conical by its shape portion 12b on the one side (left side of Fig. 2 (b)) on long limit is arranged on supporting member 43 via the force application component 42 of spring etc., and the conical by its shape portion 12a of the another side (right side of Fig. 2 (b)) on long limit is fixed on supporting member 43.In addition, minor face conical by its shape portion 12b be arranged on supporting member 43 via the force application component 42 of spring etc., the conical by its shape portion 12a of minor face another side is fixed on supporting member 43.
Then, illustrate by the effect of the present embodiment of this Structure composing.
First, the holder 20a of maintaining part 20 rotates, thus is clamped by this maintaining part 20 and keep mould component 61 (with reference to Fig. 1).At this, in mould component 61, be filled with internals 63, from the top insert cover component 62 of mould component 61.
Then, by lifting unit 50, below rotating part 45b is moved upward, thus mould component 61 and lid component 62 is lifted upward (with reference to Fig. 4 (a)).
When mould component 61 and lid component 62 being lifted upward like this, first the lower surface of lid component 62 and temporary fixed pin 41 abuts (with reference to Fig. 4 (b)).In addition, during mould component 61 and lid component 62 are lifted upward, the lower surface of temporary fixed pin 41 is moved upward along with the motion of lid component 62.In addition, temporary fixed pin 41 is linked to the force application component (not shown) of spring etc., by this force application component imparting active force downwards.In addition, this active force becomes the power of lifting that is less than and mould component 61 and lid component 62 lifted upward by lifting unit 50 and clamps mould component 61 by upper and lower location division 40 and lifting unit 50 and be placed in the chucking power of the lid component 62 on this mould component 61.Like this, lid component 62 is exerted a force by temporary fixed pin 41, so lid component 62 takeoffs and departs from mould component 61 when can prevent lid component 62 from contacting with registration roller 10, or the position of lid component 62 offsets the degree that cannot position.
Then, registration roller 10 contacts the side of lid component 62, carries out the location (with reference to Fig. 4 (c)) of the horizontal direction of this registration roller 10.At this moment, the registration roller 10a by being fixed on supporting member 43 decides the horizontal level of lid component 62.Therefore, it is possible to such as described later carried out the welding of lid component 62 and mould component 61 by laser L before correctly determine the horizontal level of lid component 62.
Afterwards, lid component 62 abuts with location division up and down 40 fixing in the vertical direction, and the gap of the above-below direction between the peripheral ends of lid component 62 and the peripheral ends of mould component 61 is eliminated (with reference to Fig. 4 (c)).Its result, by upper and lower location division 40 and maintaining part 20, makes the lid component 62 of locating in the horizontal direction and mould component 61 be clamped in the vertical direction.At this, because upper and lower location division 40 is fixed in the vertical direction, so the border of lid component 62 and mould component 61 can be made correctly to be positioned at certain height and position.Therefore, it is possible to do not carry out the position adjustment of the short transverse of the laser L irradiated and carry out easily as described later by the welding of laser L to lid component 62 and mould component 61.
Then, after receiving the signal from control part 80, the axle 91a in dynamic portion 91 extends in the vertical direction relative to upper and lower location division 40 up and down, thus whole registration roller 10 is placed in retreating position (present embodiment is top position) (with reference to Fig. 4 (d) and Fig. 5 (a)).In addition, illustrated in Fig. 4 (d) that the registration roller 10 being positioned at retreating position completely departs from from lid component 62 and moves to the form of the position do not contacted, Fig. 5 (a) shows registration roller 10 incomplete the disengaging from lid component 62 being positioned at retreating position and the form contacted with lid component 62.
Afterwards, after receiving the signal from control part 80, the laser irradiating part 30 irradiating laser L starts to move linearly by laser moving part 31.At this moment, after receiving the signal from control part 80, laser L is irradiated, by this laser L to welding between the peripheral ends of mould component 61 and the peripheral ends of lid component 62 (with reference to Fig. 5 (a)-(c)) from laser irradiating part 30.In addition, when handling object is changed to long limit from minor face or changes to minor face from long limit, below rotating part 45b and top rotating part 45a rotates, and mould component 61 and lid component 62 also rotate thereupon.
According to the present embodiment, after having carried out the location of the horizontal direction of lid component 62 above by registration roller 10, clamp up and down and fixed, having been applied energy to weld to mould component 61 and lid component 62 by laser L.Therefore, it is possible to lid component 62 is set to correct position relative to the horizontal level of mould component 61, the welding eliminated between failure welding or each component is uneven.
Namely, sometimes can there is offsetting relative to mould component 61 in the position of the horizontal direction of lid component 62, in this case, if the location of not carrying out the horizontal level of lid component 62 is just welded by laser L, then the position that lid component 62 exposes partially (position in the left side of Figure 14) laser just irradiate less than.Therefore, not soldered between mould component 61 and lid component 62 (welding insufficient), become the problem that welding between failure welding between mould component 61 and lid component 62 or each component is uneven, but according to the present embodiment, such problem can be prevented.
In addition, in the present embodiment, before carrying out the location of the horizontal direction of lid component 62 by registration roller 10, lid component 62 is made to abut with the lower surface of temporary fixed pin 41 (with reference to Fig. 4 (b)) in advance.Therefore, when (under the horizontal level of lid component 62 offsets the situation such as larger) lid component 62 contacts with registration roller 10, can prevent lid component 62 from departing from from mould component 61, or the position of lid component 62 offset the degree that cannot position.
In addition, above-mentionedly utilize rectangular cross section to describe the cross section of mould component 61 and lid component 62, but be not limited thereto, the cross section of mould component 61 and lid component 62 as also can be as roughly rectangle (having led the rectangle of fillet) or roughly square roughly quadrangle, can also be the shape be made up of elliptical shape or oblong shape.
In addition, foregoing describe and rotate by mould component 61 and lid component 62 while laser irradiating part 30 is with rectilinear movement the form that the circumference of mould component 61 and the circumference of lid component 62 are welded, but be not limited thereto.Such as also can utilize by laser irradiating part 30 form that the circumference of movement to the circumference of mould component 61 and lid component 62 is welded around mould component 61 and lid component 62, the form being made by the position in one side fixed laser irradiation portion 30 mould component 61 and the lid component 62 movement in the horizontal direction circumference to the circumference of mould component 61 and lid component 62 weld on the one hand can also be utilized.
