Field of the Invention The present invention relates to an automatic aligning and supplying apparatus for duct base plates, and more particularly, to an automatic aligning and supplying apparatus for duct base plates that are automatically aligned and supplied to roll forming machines, base plate cutting machines, and the like. Is.

Conventionally, roll forming machines have been made by placing the base plate on the work table on the entrance side by hand, so that normal molding may be hindered by a slight shift or slanting. A registered utility model No. 3087813 proposed to solve this problem is to provide an oblique rotating roll that rotates vertically on the work table on the entrance side of the duct-haze roll forming machine, and pushes the base plate placed on the work table. It is described that the inner end is brought into contact with a straight line ruler at the entrance and fed into the forming roll side.
Registered Utility Model No. 3087813

  However, the above-mentioned utility model is merely pushed by the oblique roll that rotates vertically on the upper surface of the base plate on the workbench, so that the entire length of the inner end of the base plate is reduced by idling between the diagonal roll and the base plate. There was a problem that it was difficult to run against the straight line ruler, and there was a lack of certainty about push-feeding.

  Further, since the oblique roll is fixedly attached to the work table on the entrance side of the roll forming machine, there is a problem that only this roll forming machine can be applied.

  Furthermore, since it is necessary to place the base plate on the work table manually, there is a problem that labor saving is prevented.

  The present invention forms a supply base with individual casters that can be connected to each other on the inlet side of a roll forming machine such as a duct gob or a base plate cutting machine, and presses the base above the base plate of the supply base. A roll, an oblique roll on the lower side, or a ball caster on the upper side of the base plate, and an oblique rotation roll on the upper side, push the base plate to be transferred from the cart from above and below, and push it against the linear ruler It was automatically aligned by alignment and supplied to the molding machine and cutting machine.

  As described above, the present invention newly forms a large and small supply base with casters that can face the entrance side of a roll molding machine, a base plate cutting machine, etc. Transfer and load one sheet at a time, and pinch and feed between one or more presser rolls and diagonally rotating rolls, or ball casters and diagonally rotating rolls, and press against a linear ruler for automatic alignment. Therefore, it can be supplied to a roll molding machine, a cutting machine, etc., so that accurate molding and cutting can be performed. Moreover, since the work during this time is automatic, it is labor-saving, and many effects are produced such as significantly improving work efficiency.

  The supply base and the transfer means with casters are formed according to the length, size, and size of the base plate, and one or a plurality of base plate press rolls and slant rotation rolls, and the tilt angle is 10 to 50 degrees. Since it can be adjusted by the above, it is possible to automatically align all the base plates from a large roll molding to a small cutting and supply them to a molding machine and a cutting machine.

  By providing a small roll on the inner surface of the linear ruler to reduce friction caused by pressing the base plate, it is possible to smooth the supply by automatic alignment and to reduce the burden and wear of the oblique rotating roll. Produces an effect.

  Due to the height adjusting means of the supply table and the movement adjusting means of the linear ruler, there is an effect that the base plate can be automatically aligned and supplied in accordance with the entrance ruler of various roll forming machines, cutting machines and the like.

  Since the supply base starts to supply the base plate after receiving a supply start signal from a roll forming machine, a base plate cutting machine, etc., the work management is facilitated and the power consumption is reduced.

  The present invention provides a supply base with casters that can be connected to the inlet side of a roll molding machine or a base plate cutting machine, and a linear ruler on the inner end side of the base plate of the supply base. A presser roll for the base plate that moves up and down, an oblique rotation roll that moves the base plate against the linear ruler on the lower side, a carriage that loads and transports the baseboard, and between the carriage and the supply base A transfer means for reciprocating the substrate and transferring the substrates to the supply table one by one, and pressing the substrate loaded on the supply table by the downward movement of the presser roll and pushing the oblique roll The sheet is pressed against a linear ruler by feeding and aligned, and is automatically supplied to the roll forming machine and the base plate cutting machine.

  A feed stand 3 with casters is connected to the inlet side of a roll forming machine 1 for forming a duct gob or the like or a cutting machine 2 for cutting a duct base plate into a predetermined shape.

  The supply base 3 is provided with a long straight ruler 4 for alignment at the inner end of the base plate 3a, and is provided so as to move the presser roll 5a up and down on the base plate 3a. Is provided. The peripheral surface of the inclined rotating roll 5b is flat, parallel to the ridges, and provided with a large number of protrusions to increase the coefficient of friction with the base plate S and provide flexibility so that the thickness of the base plate S can be flexibly accommodated. And slightly protrudes from the hole 3b provided in the base plate 3a. Each of the presser roll 5a and the diagonally rotating roll 5b is provided one by one or plural with an inclination angle of 10 to 50 degrees with respect to the linear ruler. The supply table 3 is made to coincide with the height of the work table of the roll forming machine 1 and the base plate cutting machine 2 by means of height adjustment means such as a screw rotation type. Further, the straight line ruler 4 is made to coincide with the entrance rulers 1a and 2a of the molding machine 1 and the cutting machine 2 by the movement adjusting means so as to form the same straight line.

  The base plate S comes next to the supply base 3 by the traveling of the loading cart 6 and is set at a fixed position. The base plate S is lifted one by one by the transfer means 7 that moves up and down there, and the base plate S is moved laterally to move the base plate S. The plate S is lowered and mounted on the base plate 3a of the supply base 3 so that the tip enters between the press roll 5a and the oblique roll 5b. The transfer means 7 is connected between endless rotation chains 8a and 8b provided on both sides of the supply table 3 and travels back and forth between the carriage 6 and the supply table 3, and passes downward through the travel table 7a. A plurality of vacuum suction cups 7d are provided at the four corners of a square plate 7c attached to the lower end of the lifting / lowering air cylinder 7b. The vacuum sucker can also be an electromagnet. Since the number of sheets loaded on the carriage 6 and the height position of the base plate S to be lifted change depending on the progress of work, a downward position detection sensor 9 is attached to the square plate 7c, and the final stage of the lowering of the vacuum sucker 7d is constant. At the height position, the supply of air to the air cylinder 7b for raising and lowering is stopped by the detection of the position detection sensor 9, and thereafter, the base plate S is moved down gently by its own weight by natural suction of very little air. Is placed on the base plate 3a as quietly as possible. The air cylinder 7b can be positioned at the center in accordance with the width of the base plate S by moving and adjusting the carriage 7a in the width direction, and the vacuum sucker 7d is rotated around the four corners of the square plate 7c. It is attached below the tip of the movable / fixable attachment arm 7e so that the adsorbing position can be adjusted according to the size of the base plate S as shown by a chain line in FIG.

  When a supply start signal is transmitted from the roll molding machine 1 or the cutting machine 2 to the base plate S placed on the base plate 3a, the presser roll 5a moves downward to press the upper surface of the base plate S and to tilt the lower side. The roll 5b is driven and rotated by the motor 5c and pushes and feeds the base plate S as shown in FIGS. 4 to 5 so that the inner end of the base plate S is brought into contact with the linear ruler 4, and the entire inner end length is changed to the linear ruler 4. By pressing, the base plate S is automatically aligned, that is, aligned based on the linear ruler 4, and further sent out toward the roll molding machine 1 or the like. Even if a deviation or inclination occurs when the base plate S is lowered and mounted on the supply base 3, the base plate S can be aligned to be aligned by pressing the entire length of the inner end against the linear ruler 4. It becomes. The presser roll 5a and the obliquely rotating roll 5b are adjusted to 10 to 50 degrees according to the size of the base plate S or the like, that is, adjusted to an appropriate angle for pushing in the direction intersecting the straight ruler 4. At this time, if the upper presser roll 5a is formed by a free-turning roll or a non-directional free-roll (ball caster) as shown in FIGS. After the contact, the base plate S can be smoothly moved in the direction of the roll molding machine 1 or the like. Further, when the oblique rotating roll 5b is formed so as to be pivotable with a spring bias toward the adjusted angle, the oblique orientation is maintained after the base plate S comes into contact with the linear ruler 4 as shown in FIG. 6 (b). However, it is possible to make the feed of the base plate S smoothly by turning in the advancing direction together with the presser roll 5a, and to return to the original angle by spring bias when the base plate S disappears.

  When the tip of the base plate S is sandwiched between the first rolls 1b, 2b of the roll molding machine 1, the cutting machine 2, etc., the rotational rotation of the oblique rotary roll 5b is changed to idle rotation. It will run by pulling and will be nipped and fed below the second roll to perform a predetermined roll molding. When the rear end of the base plate S passes the front end of the supply table 3, the presser roll 5 a is moved up by a signal, and the next base plate S is transferred onto the supply base 3 by re-operation of the transfer means 7. It will be. Since the presser roll 5a is moved downward until the base plate S is completely passed, even if the oblique rotary roll 5b is idling, the alignment function is maintained and only the posture does not occur in the base plate S that travels. . The presser roll 5a may be driven in synchronism with the obliquely rotating roll 5b. As shown in FIG. 8, the obliquely rotating roll 5b is provided so as to be movable upward and downward, and the presser roll 5a is provided on the lower side. You can also. Further, the oblique rotation roll 5b may be moved up and down from below the base plate 3a.

  FIG. 9 shows an example in which many small rolls 10 are fitted on the inner surface of the straight ruler 4. The running friction when the inner end of the base plate S is pressed against the inner surface of the linear ruler 4 is reduced and smoothed. In addition, ball casters 11 may be provided on the base plate 3a to make it easier to slide the base plate S.

  In FIG. 10, the base plate 3a is formed in a full form without holes 3b, and ball casters 11 are provided at intervals on the entire surface of the base plate 3a, and an oblique rotating roll 5b is provided so as to move up and down. An example is shown. The base plate S is supported by the omnidirectional ball caster 11 and slides on the entire surface, so that the diagonal movement of the automatic alignment by the oblique rotation roll 5b and the subsequent linear feed become smooth, and the base plate 3a. Scratching is prevented by not sliding on the top.

  The present invention can automatically supply and align and align the base plate. Therefore, the present invention is widely used in roll forming machines, base plate cutting machines, and any other apparatus that receives and processes the base plate. There is great potential that can be done.
