The present invention relates to a conveying device for a workpiece in a conveyor line mainly used in an automated factory.

In general, the conventional conveyor transfer line for transferring the workpiece of the panel type is made by using a trolley conveyor for mass continuous transfer, and adopts the method of hanging the workpiece on the hanger. Therefore, when transferring the workpieces with relatively small widths and widths, if the transfer line is properly installed in the area occupied by the entire equipment, the space can be efficiently utilized, but the wide workpieces, for example, cabinet panels, elevators, etc. Panel-type workpieces such as panels, such as panels, which are relatively large in width and length, are inevitably elongated when the width or length of the workpiece is conveyed in the width or length direction, thereby preventing utilization of the facility space efficiently.

For example, as shown in FIG. 1, in the conventional case of installing a painting line using a panel-type workpiece, the pretreatment device 1, the water channel 2, the cooling device 3) The transfer line 9 of the trolley conveyor and the workpiece of the panel type from the painting device 4, 5, the baking oven 6 and the cooling device 7 to the discharge path B. (8) is to be conveyed in the longitudinal direction, the length of the entire conveying line (9) is not only long, but also the pretreatment device (1), water channel (2), cooling devices (3, 7) and heat treatment furnace (6) and Even in the same individual device, the proper transport speed of the entire transport line 9 must be maintained together with the required time required for the workpiece 8 to be processed in each device, so that each device size must be enlarged. Closing is occurring and accordingly the size of the plant including the entire transfer line 9 is required. Increases over because there are non-economic aspects eventually not efficiently utilize the effective footprint of the facility.

In addition, Japanese Patent Application Laid-open No. 58-17010 "Automatic Transfer Device" has been disclosed as being developed to solve the above disadvantage to some extent, but in this case, the loading and dripping in one direction during the transfer of the workpiece due to the configuration of the hook and the rotating arm. Because it is only possible to do so, the design and layout of the entire transfer line will be greatly limited, and thus, it will be difficult to effectively utilize the effective installation area of the plant's internal facilities.

The present invention has been researched and developed to solve such a conventional closed end, and improves the conveying line of the conveyor and can be utilized appropriately regardless of the conveying direction or the transfer position of the workpiece, so that the width of the panel is relatively large and wide Conveyors and hangers make it possible to carry out load transfer and drip processing efficiently even in a smaller space than in the prior art, and accordingly, a large number of individual internal processing devices that make up the entire facility as well as the entire facility can be reduced in size. The purpose is to make more efficient use of the effective area and effective space occupied by the entire facility.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a schematic diagram showing a conveyor line for illustrating an example of applying the transfer device according to the present invention, which is shown as a case of changing the conventional transfer conveyor line shown in FIG.

Here, as in the conveyor line shown in FIG. 1, the process line includes the pretreatment device 10, the cutting drying device 20, the cooling device 30, the coating devices 40, 50, and the heat treatment furnace from the access road A. It can be seen that the processing sequence is made in the same way up to the discharge path B which goes out through the 50 and the cooling device 70.

However, in the pretreatment apparatus 1, the water channel 2, the cooling apparatuses 3 and 7, and the heat treatment furnace 6 shown in FIG. 1, the conveying direction of the workpiece 8 is mutually different from the width or length direction. Contrary to the point in which the conveying line is formed to coincide, the pre-treatment apparatus 10, the cut-drying apparatus 20, the cooling apparatus 30, the heat treatment furnace 60 and the cooling system in the conveyor line shown in FIG. The apparatus 70 forms the structure of a conveying conveyor line so that the conveyance direction of a conveyor and the width direction of the to-be-processed object 8 may mutually orthogonally cross.

That is, in the present invention, the orthogonal conveyance which transfers the workpiece so that the width direction of the workpiece and the transfer direction of the workpiece coincide with each other, and the orthogonal transfer that orthogonally crosses the width direction of the workpiece and the transfer direction of the workpiece. The direction change feed so that the direction change is made between the direction coincidence feed and the orthogonal feed from the direction coincidence feed to the orthogonal feed or from the orthogonal feed to the direction coincidence feed properly regardless of the conveying direction. A device for transporting workpieces that can be combined is adopted.

That is, the workpiece transfer device of the present invention, as shown in Figures 3 to 5, the direction matching is carried out by the direction matching conveyor line 100 so that the width direction and the transfer direction of the workpiece (8) coincide with each other Orthogonal transfer is made by the orthogonal transfer conveyor line 200 so that the width direction and the transfer direction of the workpiece 8 are orthogonal, and between the direction-matched transfer conveyor line 100 and the orthogonal transfer conveyor line 100. The direction change movement is performed by the direction change transfer mechanism 300, the workpiece hanger 400 is fixed to the lower portion of the horizontal member 401, the chain seating member 405, 405 and the chain seating member 405. Hook portion 406 is fixedly installed between the 405 and the workpiece (8) to the hook portion 406 in the state of the direction transfer conveyor line 100, orthogonal transfer conveyor line 200 and The blood is turned by the redirection transfer mechanism 300. In the conventional conveying apparatus which enables the conveyance of the tribute 8, the direction-matched conveying conveyor line 100 is provided with a pair of conveying hangers 102 and 102 at predetermined intervals, and each conveying hanger 102 is provided. 102 is a vertical member 103, 103 is fixedly installed so that the V-shaped cross section engaging members 103a, 103a face each other, the upper portion of the vertical member 103, 103 is a vertical support member Fixed to the horizontal members 104 and 104 having the 104a and 104a, and the vertical support members 104a and 104a are mutually coupled with the transfer chain 101 by the fixed sales 105 and 105. And, the redirection transfer mechanism 300 is fixed to the rod-shaped slide projecting member 303 on the upper side of the two side sale 302, the lower portion is made by fixing to the transfer chain 304, the workpiece hanger 400 The vertical support members 402 and 402 fixed with rod-shaped protruding pieces 403 and 403 are fixed to the upper portion of the horizontal member 401, and are provided at both ends of the horizontal member 401. The brackets 404 and 404 provided with the engaging pieces 404a and 404a of the inverted V-shaped cross section are fixed to each other.

Of course, at this time, on both lower sides of the horizontal member 401, the chain seating members 405 and 405 are fixed to each other so that the orthogonal transport conveyor line 200 formed of a general chain conveyor is fixed, and the chain seating member. Between the 405 and 405, the hook portion 406, in which the irregularities are repeatedly bent, is fixedly installed to hang the work 8 thereon.

5 shows a modification of the redirection transfer mechanism 300. The redirection transfer mechanism 300 'fixes the slide protruding member 303 to the upper portion of the support rod 305, The lower portion of the 305 is installed on the shaft 307 to which the chain sprocket 306 is fixed. When the chain sprocket 306 is rotated by the chain 308, the support rod 305 together with the shaft 307 rotates and slides accordingly. The protruding member 303 shows a shape configured to have a circular motion with a radius of the length of the support rod 305 reaching the slide protruding member 303 about the shaft 307.

Next, the operation and effects of the present invention made as described above will be described.

That is, when the width direction of the workpiece 8 and the conveying direction of the conveying conveyor coincide with each other, the workpiece 8 is attached to the hook portion 406 as shown in FIGS. 3 and 6. With the protruding pieces 403 and 403 of the workpiece hanger 400 hanging on both sides of the engaging members 103a and 103a of the transfer hangers 102 and 102 while being suspended, the trolley conveyor is transported by the direction matching conveyor line 100. As the chain 101 moves, the workpiece 8 together with the transfer hanger 102 and the workpiece hanger 400 fixedly installed on the transfer chain 101 is successively transferred.

When orthogonal transfer is performed such that the width direction of the workpiece 8 and the transfer direction of the transfer conveyor are orthogonal to each other in connection with such a transfer operation, the workpieces (as shown in FIGS. 3 and 7 to 9) 8) The longitudinal direction transfer mechanisms 300 and 300 'installed in the orthogonal transfer direction are rotated by the transfer chain 304 or the shaft 307 while being suspended in the hook portion 406 of the workpiece hanger 400. While being transported by the two side slide protruding member 303 by walking under the locking pieces (404a, 404a) of the workpiece hanger 400, and fixed to the horizontal member 401 of the workpiece hanger 400 The protruding pieces 403 and 403 on the upper side of the vertical support members 402 and 402 are separated from the upper portions of the engaging members 103a and 103a of the transfer hangers 102 and 102 to terminate the transfer of the workpiece 8 in the longitudinal direction. Hanger 400 is the redirection transfer mechanism 300 And the chain seating members on both sides of the workpiece hanger 400 on the chain of the orthogonal conveying conveyor line 200 installed in the orthogonal conveying direction while the conveying direction is converted to the orthogonal direction while being seated at 300 '. 405, 405, the inner side is seated and at the same time the redirection transfer mechanism (300,300 ') (continue rotating while leaving the lower side of the engaging piece (404a, 404a) of the workpiece hanger 400, the engaging piece of the workpiece hanger 400 The workpiece hanger 400 and the workpiece 8 suspended therefrom are separated from the lower side of the 404a and 404a, and the operation of transferring the workpiece to the orthogonal transfer direction in the longitudinal direction is performed successively.

When the widthwise conveyance of the workpiece 8 is converted to the longitudinal conveyance again, the operation is performed in the reverse order by the reverse rotation conveyance operation of the redirection transfer mechanisms 300 and 300 'and is continuously performed. The widthwise transfer of the workpiece 8 is performed by the transfer operation of the repetitive workpiece 8, which is performed according to the above-described operating sequence. In more detail, the redirection transfer mechanism 300, 300 'will transfer the workpiece. While rotating by the chain 304 or the shaft 307 and at the same time the slide protruding member 303 on both sides also rotated, the workpiece hanger 400 on which the workpiece 8 is suspended is orthogonal transfer conveyor line ( The slide protruding member 303 of the reversing transfer mechanism 300, 300 ′ is lowered on the engaging pieces 404a, 404a of the workpiece hanger 400 while being placed on the chain of 200. Transfer chain 101 of the direction-consistent conveying conveyor line 100 in which the workpiece hanger 400 is separated from the orthogonal conveying conveyor line 200 and rotated and then conveyed in a longitudinal direction while being rotated from each other. The projecting pieces 403 and 403 of the workpiece hanger 400 are seated and caught from the upper side by the engaging members 103a and 103a of the transfer hangers 102 and 102 fixed to the workpiece hanger 400. Transfer in the longitudinal direction by the (100) proceeds continuously and again the conversion of the widthwise transfer is caught in the transfer hangers (102, 102) fixed to the transfer chain 101 of the direction matched conveyor line 100 as described above The projection hangers 403 and 403 of the workpiece hanger 400, which are hanging on the workpiece 400, are lifted by the slide protruding member 303 of the redirection transfer mechanism 300, 300 'to rotate the transfer hanger 1 02) to separate the chain seating members 405, 405 of the workpiece hanger (8) on the orthogonal conveyance conveyor line 200 is carried out to change the direction from the consistent transfer of the workpiece (8) to orthogonal transfer On the contrary, regardless of the case where the direction change is made from the orthogonal feed to the coincidence feed, these operations are repeated successively.

Of course, at this time, even if the direction change transfer mechanism (300,300 ') is continuously moved by the transfer chain 304 or the shaft 307 even after the operation as described above, in the direction change transfer mechanism (300,300'), the slide projection member 303 ), And the direction change transfer by the correlation between the installation position of the transfer chain 101 and the installation position of the orthogonal transfer conveyor line 200 in the direction matching conveyor line 100 having a trolley conveyor type The operation of the instrument 300, 300 'can be continuously moved without interference.

At this time, in particular, the transfer hangers 102 and 102 have both side locking members 103a and 103a having a V-shaped cross section, and the protruding pieces 403 and 403 of the workpiece hanger 400 have a rod shape, and slide the reversing transfer mechanisms 300 and 300 '. The conveying member 303 has a rod shape, and the engaging pieces 404a and 404a of the workpiece hanger 400 have an inverted V-shaped cross section, and the workpiece 8 is hung on the direction matching conveyor line 100. In the state where the hanger 400 is hung, that is, the protrusion pieces 403 and 403 are mounted on the engaging members 103a and 103a, the workpiece hanger 400 is stably hung in the vertical direction together with the workpiece 8. Directional conveyance can be made, and the slide conveying member 303 is a conveying chain when the direction change is performed by the direction change mechanism (300,300 ') from the direction feed to the orthogonal feed or the direction is changed from the orthogonal feed to the direction coincidence. By the 304 or the axis 307 to trace the arc In this process, even when the position movement is made, the workpiece hanger 400 is stably hung in the vertical direction together with the workpiece 8 in this process or in a state where the locking pieces 404a and 404a are placed on the slide transfer member 303. Therefore, the protrusion pieces 403 and 403 of the workpiece hanger 400 may be made smoothly in the process of being separated from the catching members 103a and 103a or seated on the catching members 103a and 103a. In addition, due to the structural characteristics of the engaging members 103a and 103a and the protruding pieces 403 and 403, and the slide conveying member 303 and the engaging pieces 404a and 404a, separation or mounting processes or states can be stably maintained. Regardless of the direction of rotation of the member 303 has the advantage that can be operated accordingly has the advantage that the structure of the turning mechanism (300,300 ') can be simplified.

Therefore, the present invention provides a direction consistent feed such that the width direction and the feed direction of the workpiece 8 coincide with each other, an orthogonal feed such that the width direction and the feed direction of the workpiece 8 are perpendicular to each other, and the direction matched feed. A device for conveying a workpiece in which a reversal transfer is performed so that the reversal of the orthogonal transfer is performed. As the width direction of the workpiece 8 and the conveying direction of the conveying conveyor coincide with each other, a direction matching conveying conveyor line 100 and various The internal processing apparatus is subjected to the direction change transfer mechanism for the direction change between the orthogonal conveying conveyor line 200 and the conveying conveyor line (100,200) so that the conveying direction of the conveying conveyor of the workpiece 8 is orthogonal to each other. (300,300 '), and the workpiece is provided by a combination of the workpiece hanger 400 to hang the workpiece (8) to carry out the transfer and redirection In addition, even in the workpiece 8 having a wide panel shape having a relatively large width × length, the locking members 103a may be connected to the direction-conveying conveyor lines 100 and 200, the direction transfer mechanisms 300 and 300 ′, and the workpiece hanger 400. 103a), the slide conveying member 303, the protruding pieces 403 and 403, and the engaging pieces 404a and 404a are adopted so that they can be appropriately changed regardless of the conveying direction and position of the workpiece 8 By shortening the pitch between the workpieces 8, the entire conveying line can be reduced while efficiently transporting and processing in a smaller space than before, and accordingly, the internal processing apparatus or the whole facility arranged separately can be reduced.
