Description
Technical field
The conveyer and the method that transmits thin sheet like plate of the thin sheet like plate that the present invention relates to be used for particularly to be adjacent to each other and be welded to one another.
Background technology
For example; Be used to form at the steel plate that will have different materials and thickness under the situation of adjacent part or part of vehicle body for example; Must be in a longitudinal direction through using continuous welding equipment; Continuously two or more thin sheet like plate (steel plate) that before cut into accurate rectangular shape are welded, thereby form special blank material.
As thin sheet like plate being welded to form the method for special blank material; Following method is provided; Wherein, A plurality of thin sheet like plate are fixed on its end surface are adjacent to each other between the Cheng Zaiqi under the state very close to each other, through use along bound fraction movably welding robot a plurality of thin sheet like plate are welded.Following method also is provided, wherein, a plurality of thin sheet like plate has been moved, then through using fixed welding robot that a plurality of thin sheet like plate are welded to one another.
The transfer member of each that is used for making the continuous welding equipment of the method that thin sheet like plate moves to comprise above the utilization being respectively applied for two thin plates, and in the transfer member each all has with inclined at acute angles and has the transmission surface of step in vertical direction.For example, as disclosed in the japanese patent publication thing No.HEI 613153, at the part place before welding robot just, these transmit the surface and are merged into common horizontal surface.
Yet; According to announcing the thin sheet like plate transfer member that is used for continuous welding equipment disclosed in the thing in this patent; Transmit the surface with inclined at acute angles and have step in vertical direction, and just before welding assembly is the welding position, transmit the surperficial common horizontal surface that is merged into.Therefore, if accurately the guide member that is equipped with for each transfer member is not made adjusting, so just possibly cause as the end that thin plate will be soldered overlapping or between it disadvantageous possibility generation gap.Therefore, expectability does not have good welding condition, from but inconvenient.
And because transfer member itself is equipped with respectively to two thin plates, so the adjusting between it, for example position adjustments just needs great amount of time and work, comprises extra work.
In addition, the guiding surface of guide member is contacted slidably with the end that thin plate will be soldered, therefore can predict because the variation of the guide position that wearing and tearing cause.Yet; In the structure of relative side through different two thin plates of transmission surface guiding; Through wearing and tearing the relative position of guiding surface (surface that will be directed) is changed, and when carrying out such wearing and tearing, possibly make the end that will be soldered take place vertically superposed.Thereby, need regulate to do to the relative position between two thin plates and make regular check on, from but inconvenient.
Then, proposed guide rolls,, be used for confirming the transmission center of thin sheet like plate as guide member.Make the end surface of the end surface of thin thin plate (being thin plate hereinafter) through guide rolls, thereby the surface of adjacency is positioned on the constant position in abutting connection with thicker thin plate (being slab hereinafter).Also proposed following technology, wherein, made thin plate be deformed into the corrugated shape, sliding with the end surface of slab.
At that time, if flatly guide guide rolls (guiding its pivot center in vertical direction), so because slab has adopted desirable rolling contact, so the degree that possibly reduce to wear and tear.Yet,, so will increase its deflection inevitably, make the glacing flatness on the surface of adjacency become poorer, and make the worsening condition that adheres to respect to slab because thin plate must be walked around guide rolls.
In addition, in order to make thin plate be deformed into the shape of corrugated additional parts is provided separately, this is necessary, thereby makes the overall structure of equipment become complicated.
With regard to this; If vertically guide guide rolls (guiding its pivot center in the horizontal direction); The thin plate that under guide rolls, passes through so will adopt desirable corrugated shape, but according to the amount of movement towards the thin sheet like plate core, have to widen the width of guide rolls.Thus, when making thin plate be deformed into the corrugated shape, just produced resistance, and this has influenced transfer operation unfriendly, it possibly cause as the transfer rate misgivings unstable that become.
In addition, disadvantageous possibility below also existing: guiding surface and the contact area between the slab in guide rolls are increased, transmit the resistance increase, and wearing and tearing are increased because the sliding-contact between it makes.In addition; The guiding surface of guide rolls is cut sth. askew; This is necessary, to avoid at the guiding surface of guide rolls and the interlocking between the slab amount that this interlocking possibly make the deflection increase of thin plate cut sth. askew; Make the glacing flatness on the surface of adjacency become poorer, and make the deterioration of adhering to of slab.

On transfer path 17A and 17B; Two thin sheet like plate 7A and 7B are transmitted towards welding robot 6, simultaneously, move closer to each other; Thereby, make the end 21A and the 21B that will be soldered be adjacent to each other (checking Fig. 2 and 3) at the upstream side of the welding robot 6 of the outlet side that is arranged on transfer path 17A and 17B.Grip roller 14 is arranged in the scope except the input position of thin sheet like plate 7A and 7B.
In this embodiment, a plurality of guide rolls 23 were set in place just before the welding robot 6 of the outlet side of the transfer path 17B of the thin plate 7B of transfer path 17A and 17B.As in lateral plan, observing; Guide rolls 23 is arranged on the thin plate 7B; And as in plan view, observing; Guide rolls 23 is arranged on and is written into roller 10 and is promptly transmitting between the transmission roller that is arranged in parallel with each other on the roller direction of advance, is written into roller 10 and alternately arranges with guide rolls 23 thereby promptly make.In addition, these guide rolls 23 are supported on the device framework, the turning cylinder 16 of the grip roller 14 of grip unit 9 also supports on this device framework.Supporting guide roller 23 is so that it is through the rotation freely of passing through of the thin plate on the transmission roller that for example rotates through motor 12.
In addition; Example embodiment of the present invention can be used the guide rolls 23 with various structure; As the guide rolls 23a described and with reference to figure 5 to 7 in the back as the guide rolls 23b described with reference to figure 8 to 10 in the back; And be noted that reason for convenience, the guide rolls 23 that the Fig. 2 to 4 that mentions in front showed has represented guide rolls 23b.
Shown in Fig. 5 and 7; In an example embodiment; Guide rolls 23 (being guide rolls 23a in this embodiment) is set in their position; Thereby, make it to be lower than the slab 7A that transmits through another transfer path 17A, thereby form crooked recess or sunk part 24 between the roller 10 being written into of a transfer path 17B roughly partly to promote to pass through the thin plate 7B of a transfer path 17B transmission downwards corresponding to the amount of thin plate 7B thickness.
More specifically; As before mentioned; In the guide rolls 23 (23a, 23b) each all is arranged between the adjacent transmission roller 10 (11), and be gapped between it, and the thin plate on a transfer path can pass through this gap; Through guide rolls 23 thin plate is pressed down predetermined amount, its end that will be soldered is maintained in the horizontal plane identical with the horizontal plane of another transfer path.
In addition, in this embodiment, on the center side axial direction in the vertical plane that is positioned at the welding position through welding robot 6, form and have guide rolls 23a as the end surface of guiding surface.In addition, has smooth transmission surface through another transfer path 17A that is written into roller 10 formation.
Guide rolls 23a is used for the welding position that is directed to welding robot 6 than the thin plate 7A of slab thickness with having as guide member.End surface on the side axial direction of the center of guide rolls 23a is as guiding surface 25 (being guiding surface 25a) in this embodiment; Be used for central axis 18 along conveyer 3; Through the end 21A that promotes will be soldered by the thin plate 7A that is written into roller 10 transmission, the end 21A that thin plate 7A will be soldered is directed to the position before welding robot 6 just.On the other hand; As thin plate 7B the time near welding robot 6; Promotion have than lamella thickness pass through be written on another thin plate 7A that end 21B that thin plate 7B that roller 10 transmits will be soldered leans against the guiding surface 25a guiding through guide rolls 23a, the end 21B that at last thin plate 7B will be soldered is directed to the vertical surface through the central axis 18 of conveyer 3.
According to this embodiment shown in Fig. 5 to 7; The end 21A that the thin plate 7A that promotion guides with predetermined form through guide rolls 23a will be soldered; And at welding robot 6 is the welding position or the pad place of the central axis 18 of conveyer 3, and the end 21A that thin plate 7A will be soldered abuts against on the end 21B that another thin plate 7B will be soldered.Therefore, only, just can regulate, so just simplify the adjusting operation through regulating one the guiding surface 25a (end surface on the side axial direction of center) among the thin plate 7A.
In addition; In this embodiment; With the state that on different transfer path 17A with common horizontal surface and 17B, two end 21A and 21B is adjacent to each other along whole longitudinal direction; Can two thin plate 7A and 7B be sent in the welding position of welding robot 6, during transmitting thin plate 7A and 7B, just prevent that end 21A and 21B are overlapping in vertical direction like this.
In addition, have one guiding surface 25a (end surface on the side axial direction of center) that only is used for thin plate 7A and the guide rolls 23a that does not have the guiding surface that is used for another thin plate 7B owing to having formed.Therefore; Even make the guiding surface 25a wearing and tearing of guide rolls 23a through sliding-contact with the end 21A of thin plate 7A; The relative position that also can not cause guiding surface 25a changes, therefore, even under the situation of not carrying out regular relative position adjusting; Also can keep high quality welding, be favourable like this.
In addition; Described as in the above; With following state; Can two thin plate 7A and 7B be sent to welding robot 6: two end 21A and 21B are adjacent to each other, and when when making guide rolls 23a with the position that is written into roller 10 vertical fluctuation taken place repeatedly, the end 21B of thin plate 7B is the end 21A of contact sheet 7A slidably.Therefore, the burr that during thin plate 7A and 7B are sheared, produces or similar thing can be automatically removed, the surface smoothing property or the performance of the abutment surface of the end 21A that will be soldered and 21B can be improved thus through such sliding-contact.
On the other hand; Mentioned as hereinbefore; Fig. 8 to 10 has represented another example embodiment of the present invention; Guide rolls 23 (being guide rolls 23b in this embodiment) is set in their position therein; Thereby, make it to be lower than the slab 7A that transmits through another transfer path 17A, thereby form crooked recess or sunk part 24 between the roller 10 being written into of a transfer path 17B roughly partly to promote to pass through the thin plate 7B of a transfer path 17B transmission downwards corresponding to the amount of thin plate 7B thickness.
In other words, as before mentioned with regard to the embodiment of front, each among the guide rolls 23b all is arranged between the adjacent transmission roller 10 (11) with certain interval, and thin plate passes through this gap with pressed status.
Guide rolls 23b can be configured for slab 7A is directed to another guide instrument of the welding position of welding robot 6.On the side axial direction of center, the i.e. end surface in the vertical surface of the welding position through welding robot 6 of vertical surface that the central axis 18 that is positioned at conveyer 3 passes through is provided, as guiding surface 25 (being guiding surface 25b in this embodiment).When promoting when being written into end 21A that thin plate 7A that roller 10 transmits will be soldered and leaning against on this guiding surface 25b, be right after the end 21A that before welding robot 6, guides slab 7A to be soldered along the central axis 18 of conveyer 3.
Guide rolls 23b is tapered; Thereby the peripheral surface 26 that forms abutment surface with respect to thin plate 7B is increased towards the axial end surface that forms guiding surface 25b on diameter gradually, thereby and guide rolls 23b is set its pivot center 27 is tilted with respect to transmitting the surface in vertical direction.
More preferably, the peripheral surface 26 of guide rolls 23b is set, thereby the exterior lateral sides that makes it is inclined upwardly with respect to the transmission surface of smooth transfer path 17B, and the vertical surface side of pivot center 27 is inclined upwardly.
The width of guide rolls 23b forms less than the width that is written into roller 10 that constitutes transfer path 17B; Side in the vertical surface through the welding position only is provided with guide rolls 23b, and guiding surface 25b has the height of the thickness that is higher than the thin plate 7A that abuts against on the guiding surface 25b at least.
As in plan view, observing, for the guiding surface 25b of the end surface of the guide rolls 23b on axial direction, the entrance side at least of transfer path 17A and 17B is outwards open.
As thin plate 7B the time near the welding position of welding robot 6; The end 21B of promotion through the thin plate 7B that is written into roller 10 and transmits leans against on the end 21A through another thin plate 7A of guiding surface 25b guiding; This guiding surface 25b is the central side end surfaces of guide rolls 23b on axial direction, at last the vertical surface guiding end 21B that passes through of the central axis 18 through conveyer 3.
This example embodiment will work by following mode and turn round.
Form the central side end surfaces of guide rolls 23b, as guiding surface 25b, the thin plate 7A that this central side end surfaces will be thicker is directed to the welding position of the welding robot 6 in the vertical surface that on axial direction, is positioned at the welding position through welding robot 6.Guide rolls 23b is tapered; Thereby thereby make peripheral surface 26 increase formation guiding surface 25b gradually towards the end surface on axial direction on the diameter with respect to veryyer thin plate 7B formation abutment surface; And the peripheral surface 26 of guide rolls 23b is set, thereby the exterior lateral sides that makes it is inclined upwardly with respect to the transmission surface of smooth transfer path 17B.
In addition; The width of guide rolls 23b forms less than the width that is written into roller 10 that constitutes transfer path 17B; Side in the vertical surface through the welding position only is provided with guide rolls 23b, and guiding surface 25b has the height of setting the thickness that is higher than the slab 7A that abuts against on the guiding surface 25b at least.Therefore, can be smoothly be transmitted end 21A and the 21B that the thin sheet like plate 7A that separates with side direction each other and 7B will be soldered and be directed to vertical surface through the welding position with two.
In addition, the pivot center 27 of guide rolls 23b is set to respect to transmit the surface and tilts in vertical direction, and the side of the vertical surface through the welding position is inclined upwardly.On axial direction, form the guiding surface 25b of the end surface of guide rolls 23b, thereby the entrance side at least of transfer path 17A and 17B is opened toward the outer side as in plan view, observing.
Therefore; Make through promptly thicker thin plate (slab) 7A of thin sheet like plate to avoid being directed roller 23b interlock, and the end 21A that can reliably slab 7A will be soldered is directed to the welding position in the guiding surface 25b guiding that on the end surface of guide rolls 23b, forms on the axial direction.
In addition,,, can set the outer dia of guide rolls 23b for minimum of a value, so just can reduce the deflection of thin plate 7B so the work of cutting sth. askew that in conventional art, needs becomes not necessarily because slab 7A is avoided by interlock.
In addition, the contact portion between the end 21A of guiding surface 25b and slab 7A has constituted the some contact that is different from the surface contact, has so just reduced the distortion of slab 7A.The width that can make guide rolls 23b is constant, no matter the amount of movement of thin sheet like plate 7A and 7B.Therefore, owing to according to conical by its shape thin plate 7B is out of shape gradually, institute and can reduce the zone that is out of shape or is out of shape, and also can reduce the influence to transfer rate so that resistance is able to reduce.In addition, can reduce, therefore also reduce wearing and tearing in thicker thin plate 7A and the slip between the guide rolls 23b.
In addition, the thickness of the thin sheet like plate 7B that on the side that is provided with guide rolls 23b of adjacent transfer path 17A and 17B, transmits forms the thickness that is thinner than thin sheet like plate 7A.Therefore, can reduce to have the deflection that passes through the crooked thin plate 7B of guide rolls 23b (thin plate) than lamella thickness.Therefore, the glacing flatness of abutment surface can be improved, and also adhering to can be improved with respect to slab 7A with respect to slab 7A.
Mentioned as hereinbefore; According to a preferred embodiment of the invention, provide like this and be used for can when thin sheet like plate is transmitted operation, under the overlapping in vertical direction situation in the end that a plurality of thin sheet like plate will be soldered, making of thin sheet like plate and regulate the simple conveyer that becomes.
It is also noted that the present invention is not limited to described embodiment, and under the situation of the scope that does not depart from additional claims, many other variations and change can take place.
