Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a line supply device for automatically supplying a line supply such as a service tail to a predetermined line such as a pickling line.

As a conventional line supply device of this type, there is known a device that automatically supplies a rectangular plate-shaped service tail to a picking line. That is, as shown in FIG. 8 and FIG. 9, this line supply device has a placement work position (the position shown in FIG. 8A) and a delivery position (the position shown in FIG. (C) position) and the carriage 1 which can be self-propelled, and the straight line 22 orthogonal to the traveling direction of the line 3, the standby position on the carriage 1 (position in FIG. 8C) and the supply on the line 3. The automatic transfer machine 2 provided with the sheet loader 21 whose travel is controlled over the position (FIG. 9 (G) position), and is a service tail mounted on the carriage 1 as follows. The line supply 4 is automatically supplied to the line 3 by the transfer machine 2.

First, the stacked line supply groups 4 ... Are placed and supplied on the carriage 1 placed at the placement work position by an artificial operation by the overhead crane 5 (FIG. 8 (A)). (B)), and bring the cart 1 to the delivery position ((C) in the same figure). Next, the sheet lifter 21a of the sheet loader 21 located at the standby position descends to adsorb the uppermost line supply 4 and lift it (FIGS. 8D and 9E). After that, the sheet loader 21 travels from the standby position to the supply position and brings the line supply material 4 onto the line 3 (FIG. 9 (F)). Then, in response to a command from the line 3, the sheet lifter 21a descends to supply the line supply 4 onto the line 3 (FIG. 9 (G)), the sheet loader 21 returns to the standby position, and the next time Prepare for supply ((H) in the figure).

By the way, the line supply 4 is translated in a direction orthogonal to the traveling direction of the line 3 and in the vertical direction between the carriage 1 and the transfer machine 2 to reach the line 3. Therefore, in order to accurately and automatically supply the line feed 4 to the proper position on the line 3, the traveling stop accuracy of the carriage 1 to the delivery position and the traveling of the transfer machine 2, that is, the seat loader 21 to the standby position and the supply position are required. Stopping accuracy and the placement position of the line supply 4 on the trolley 1 are important points, but the travel stop accuracy of the trolley 1 and the transfer machine 2 is at a level that is almost established by the development of the control system. However, there is no need to upgrade to a higher level than the current level because the range is sufficiently satisfactory. Therefore, in order to improve the accuracy of supplying the line supply 4 onto the line 3, it is necessary to accurately place the line supply 4 on the carriage 1 at a fixed position. That is, as shown in FIG. 7, on the mounting surface 13 of the trolley 1, in relation to the transfer machine 2, a vertical center line yy that is parallel to the traveling direction of the line 3 and a horizontal center line that is orthogonal to the traveling direction. In the case where the center line y′-y ′ is set, in order for the line supply 4 to be properly supplied to the line 3, the line supply 4 is set to the vertical center line xx and the horizontal center line xx. The center line x′-x ′ is placed at a position (the position shown in FIG. 7A, hereinafter referred to as “complete centering position”) where the center lines x−y and y′−y ′ coincide with each other. Although it is ideal to set the position, in general, there is no problem if the supply position is slightly deviated in the traveling direction of the line 3, so at least the position where the vertical center lines x-x and y-y coincide (see the same figure ( This is the position illustrated in B), and is below It is necessary that is placed on) that Ntarin grayed position ".

[0005]

[Problems to be solved by the device]

 However, since the placement supply of the line supply 4 on the trolley 1 is an artificial operation as described above, the line supply 4 is placed not only in the perfect centering position but also in the allowable centering position. It is difficult to do so, for example, when the vertical center lines xx and yy are different (as illustrated in FIG. 7C), the vertical center lines xx and yy, and the horizontal center line x ′. A case where -x 'and y'-y' both have a discrepancy (cases illustrated in (D) and (E) of the same figure) is likely to occur.

In this way, when the vertical center lines xx and yy are placed in a disagreeable state (hereinafter referred to as “improper placement state”), the line feed 4 is properly placed on the line 3. It will not be supplied and will adversely affect subsequent processes.

In the past, as a solution to such a problem, various sensors detect the mounting position on the trolley 1, and the line supply 4 is transferred from the trolley 1 on the basis of the detected data. Attempts have been made to adjust the handling form to the machine 2 and to provide a correction means for correcting the posture of the line supply 4 in the transfer path by the transfer machine 2, but this is not satisfactory. There wasn't. That is, in the case of the former, sophisticated sensor means and arithmetic means are required, and the equipment structure and control system are complicated and sophisticated, and the cycle time is lost, resulting in efficient line supply. There is a problem that it cannot be done. Moreover, when the line supply 4 is placed in an obliquely placed state as illustrated in FIG. 7 (E), the accuracy correction at the time of transfer from the carriage 1 also lacks accuracy. Also, in the latter case, there is a problem that the equipment structure and control system become complicated and large in size, and the line supply cannot be performed efficiently as in the former case.

[0008] In view of the above, the present invention provides a line supply device capable of accurately placing a line supply product at a fixed position on a trolley and appropriately supplying the line supply product. The purpose is.

[0009]

[Means for Solving the Problems]

 In the line supply device of the present invention, in order to achieve the above-mentioned object, in particular, the first and second centering action members which face the carriage with the line supply interposed therebetween in a direction orthogonal to the traveling direction of the line. Is provided so as to be movable relative to each other between a minimum distance position where the facing distance between the two centering effectors matches the width of the line supply and a maximum distance position where the width is larger than this width, and the centering effect members are kept at the minimum distance. It is proposed that the line feed be positioned at a fixed position on the carriage at least in the direction orthogonal to the direction of travel of the line by moving it relative to the position.

[0010]

[Operation] The line supply is artificially placed and supplied on the carriage with the centering body positioned at the maximum distance position. Then, the line feed placed on the trolley is clamped by the centering action body at least in the direction orthogonal to the traveling direction of the line by relatively moving the centering action body to the minimum distance position. It will be moved to a fixed position. Therefore, the minimum spacing position is the proper position desired by the position of the line supply when it is clamped by the centering action body (specifically, as shown in FIGS. 7A and 7B, the vertical center line x− (x, y−y are in the same position) so that the centering effector moves relative to the minimum distance position even when the line feed is placed in an improperly placed state. By doing so, the placement position of the line supply on the carriage can be appropriately corrected. Therefore, as long as the traveling stop accuracy of the carriage and the transfer machine is ensured, the line supply can be properly supplied to the line.

The arrangement position of the first centering action body 15 is such that when the left end faces of the line supply groups 4 are made to abut against both centering action bodies 15 and 15, the vertical center line xx of the line supply group 4 is It is set so as to coincide with the vertical center line y-y of the carriage 1 or the mounting table 13 (see FIGS. 7A and 7B). That is, in the state where the line supply groups 4 ... Are made to abut against both centering action members 15, 15, the line supply groups 4 ... Are moved to the complete centering position shown in FIG. It will be located at the illustrated allowable centering position.

As shown in FIGS. 3 to 6, each of the second centering action bodies 16 is arranged on the right side of the mounting table 13 and is supported by the machine body 12 so as to be movable left and right. That is, a plurality of rolling rollers 16a ... Are provided at the lower end of the centering work body 16, and these rolling rollers 16a. It is engaged and held immovably. Then, as shown in FIGS. 3 to 5, each centering action body 16 can be moved in the left and right direction by expanding and contracting a fluid pressure cylinder 18 such as a pneumatic cylinder interposed between the centering action body 16 and the machine body 12. It has become . Both cylinders 18 and 18 are controlled so as to be expanded and contracted in synchronization, and both second centering action members 16 and 16 are aligned with the first centering action members 15 and 15 with their positions in the left-right direction aligned. The minimum spacing position (the solid line position in FIG. 3 and the position in FIG. 3) where the facing spacing matches the lateral width W of the line supply group 4 ... and the maximum spacing position in which the width W is a predetermined amount larger (the chain line position in FIG. (5 positions).

Further, as shown in FIGS. 3 and 6, guide bodies 19 ... Are erected at the front and rear ends of the trolley 1, and the line supply groups 4 ... Guide ′ so that it does not largely deviate from the lateral center line y′-y ′ of the mounting table 13. That is, when the line supply group 4 is placed on the carriage 1 by the overhead crane 5 and supplied by the guide body 19, the line supply is controlled in order to suppress the deviation in the front-rear direction from the complete centering position within the allowable range. The object group 4 is guided.

A liner 13 a made of a resin plate (for example, a neulite plate) having a small friction coefficient is attached to the upper surface of the mounting table 13 to damage the line supply 4 or the line supply group 4. It has been devised so that it can be placed without it and can be easily moved. As shown in FIGS. 3 and 6, the mounting table 13 and the liner 13a include a wire rope 5a (see FIG. 1 (A)) that suspends and supports the line supply group 4 and a band that binds the line supply group 4 tightly. In order to secure the concave grooves 13 '..., 13'a ... For guiding under the mounting surface 13a, the structure is divided in the front-rear direction.

As shown in FIGS. 1 and 2, the transfer machine 2 includes a sheet loader 21 equipped with a vertically movable sheet lifter 21 a on a straight line path 22 orthogonal to the traveling direction of the line 3 at a delivery position. It is provided so as to be self-propelled between a standby position (Fig. 1 (D) position) which is directly above the trolley 1 located and a supply position (Fig. 2 (G) position) which is immediately above the line 3. . The sheet lifter 21a is for adsorbing the line supply 4 by a vacuum pad. By the way, the traveling of the sheet loader 21 and the ascending / descending and adsorbing operations of the sheet lifter 21a are automatically controlled by a command from the line 3, and the line supply 4 is moved to the complete centering position or the allowable centering position on the carriage 1 at the delivery position. It is controlled so that it can be supplied to an appropriate position on the line 3 when it is located in the lagging position.

According to the line supply device configured as described above, the line supply groups 4 ... Are placed at least in the left-right direction which is orthogonal to the traveling direction of the line 3 as follows. It can be placed at a fixed position, and as a result, the line supply 4 on the carriage 1 can be accurately supplied to the fixed position on the line 3 by the transfer machine 2.

First, the trolley 1 is positioned at the placement work position, the fluid pressure cylinders 18 and 18 are extended to position the second centering action members 16 and 16 at the maximum distance position, and the band is laminated. The line supply groups 4 ... Tightly bound to each other are mounted and supplied on the mounting table 13 of the carriage 1 by an artificial work by the overhead crane 5 (FIGS. 1 (A) and 4).

Then, the fluid pressure cylinders 18, 18 are contracted to move the second centering action members 16, 16 to the minimum distance position, and the position of the line supply group 4 ... The force is corrected to the perfect centering position shown in Fig. 1 or the allowable centering position shown in Fig. 1B (Figs. 1 (C), 3 and 4). That is, the line supply groups 4 ... Mounted on the carriage 1 by the ceiling crane 5 on the improper mounting state in which the vertical center line xx of the line supply group 4 does not match the vertical center line yy of the mounting table 13 ( 5, the line supply groups 4 ... Can be pushed and moved by the second centering bodies 16 and 16 even when the line supply groups 4 ... Are mounted in the states shown in FIGS. 5 and 7C to 7E. In the state where the second centering action members 16 and 16 are located at the minimum distance position and the line supply group 4 is abutted against the first centering action members 15 and 15, the vertical center line xx, y -Y is corrected to an appropriate position (see FIGS. 3 and 4). At this time, the horizontal center lines x'-x 'of the line supply group 4 ... The positional relationship with the horizontal center line y'-y 'is Although not corrected by the pressing movement by the centering action members 16, 16, these deviations between the horizontal center lines x'-x ', y'-y' are within the allowable range by the guide members 19 as described above. It can be suppressed.

After that, the carriage 1 is moved to the delivery position, and stopped and held at that position (see FIG. 1C). At this time, since the line supply groups 4 ... Are sandwiched between the first centering action members 15 and 15 and the second centering action members 16 and 16, the line feed group 4 is moved by the inertia force or the like when the carriage 1 is moved or stopped. There is no fear that the position of the supply group 4 changes.

Next, the band that binds the line supply groups 4 ... Is cut and the fluid pressure cylinders 18 and 18 are extended to move the second centering members 16 and 16 to the maximum spacing position (Fig. 1 (D)). As a result, the pinched state of the line supply group 4 ... Is released, and the handling by the transfer machine 2 described later is smoothly performed. Since the carriage 1 travels from the placement work position to the delivery position while the line supply groups 4 ... Are sandwiched by the centering acting bodies 15 and 16, the carriage 1 is located at the placement work position. You may make it cut | disconnect a band at the stage currently performed.

Then, the sheet lifter 21a descends to adsorb the uppermost line feed 4 (FIG. 1D), and the sheet lifter 21a further rises and returns to lift the line feed 4 (FIG. 2E). )), The sheet loader 21 travels from the standby position to the supply position, and brings the line supply material 4 directly above the line 3 (FIG. 2 (F)).

Further, in response to a command from the line 3, the sheet lifter 21a descends and the suction operation is released, and the line supply 4 is supplied onto the line 3 (FIG. 2 (G)). After that, the sheet lifter 21a returns to the ascending position, and the sheet loader 21 moves to the standby position to prepare for the next supply (FIG. 2 (H)).

At this time, the line supply 4 is translated in the left-right direction and the up-down direction from the carriage 1 through the transfer machine 2 to the line 3. Therefore, if the placement position of the line supply 4 on the trolley 1 is proper as described above, as long as the traveling stop accuracy of the trolley 1 and the seat loader 21 is proper, the advanced sensor means and the above-mentioned sensor means can be used. The line supply 4 is surely supplied to the proper position on the line 3 without providing a correction means or the like. Moreover, since it is not necessary to correct the posture of the line supply 4 on the transfer machine 2 side, there is no loss time required for such correction, and the supply to the line 3 is performed very efficiently.

The present invention is not limited to the above-mentioned embodiments, and can be appropriately improved and changed within the range not deviating from the basic principle of the present invention.

For example, the fixed position of the first centering effector 15 may be adjusted in the left-right direction. In this way, the centering position on the carriage 1 can be changed and adjusted according to the shape of the line supply 4 (width in the lateral direction, etc.). Further, the first centering effector 15 may be forcibly moved by a fluid pressure cylinder similarly to the second centering effector 16. Further, the number and shape of the centering work bodies 15 and 16 to be installed are arbitrary, and can be appropriately designed according to the shape of the line supply material 4. Further, instead of the guide bodies 19 ..., Centering acting bodies similar to the first and second centering acting bodies 15 and 16 may be provided in the front and rear portions of the carriage 1 so as to be movable front and rear. In this way, the line feed 4 can always be kept in the completely centering position. In addition, as described above, the correction of the placement position of the line supply 4 by the centering acting bodies 15 and 16 is performed at the stage where the carriage 1 is at the placement work position, and the carriage 1 is moved to the delivery position. It may be performed during traveling or when the dolly 1 reaches the delivery position. Of course, the means for moving the centering action members 15, 16 relative to each other is not limited to the fluid pressure cylinder 18 described above, but is arbitrary.

Various types of transfer machines 2 are known and generally selected appropriately according to the shape of the line supply 4 and the like, but the same applies to the line supply device according to the present invention. However, the transfer machine 2 used is not limited to that of the above embodiment. Further, in the above-described embodiment, the traveling route 14 of the carriage 1 and the transfer route 22 of the transfer device 2 are set in the direction orthogonal to the traveling direction of the line 3, but the routes 14 and 22 are line functions, etc. Therefore, it is possible to set the line 3 in the traveling direction.

Further, the line supply device according to the present invention is not limited to the case where the service tail 4 is supplied to the pickling line 3, but the line supply 4 is artificially placed on the trolley 1 when the coil is line supplied. It can be applied regardless of the shape of the line supply 4, the line function, etc. when the line supply 4 on the trolley 1 is automatically supplied to a fixed position on the line by the transfer machine 2 by the work. It is a thing.
