Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention is designed to continuously feed long plate materials, for example, when they are fed while exchanging the feed from each of the plurality of uncoiler bodies that are held in a roll in advance, the uncoiler bodies are fed out. The present invention relates to a long material feeding guide device capable of smoothly setting feeding of a plate material to a processing machine side and automatically applying tension when rewinding to prevent winding deviation, loosening, and the like.

[0002]

[Prior art]

 When cutting, punching, and forming various products from a long plate material with a predetermined width, such as the plate-cutting pieces of duct components, it is sequentially drawn from the raw material rolled into a roll and conveyed. It is transported to various predetermined processing machines on the line. In this transporting and sending out, multiple uncoiler bodies are juxtaposed so as to cope with, for example, differences in plate thickness, composition material, etc. corresponding to the product to be processed, and replacement of consumed raw material. It is something to keep.

That is, as shown in FIG. 3, a plurality of uncoiler bodies R formed by rolling a transported member W, which is a raw material having a predetermined width, in a roll shape are transported along a transport direction of the transport base 1 An uncoiler section is formed by sequentially arranging the uncoilers on top of each other, and each uncoiler body R is sent out separately through a guide device having an inclined structure while being exchanged, and various types of plasma cutting machines 41 and the like are arranged on the transfer line. Various processing is performed by the processing machine.

At this time, in order to replace the transported members W sent out from the respective uncoiler bodies R, it is necessary to rewind the transported members W sent up to the various processing machines (41), while it is necessary. From the uncoiler body R, the sending-out edge part is pulled out, and this is sent out in order. When the uncoiler body R is consumed, the uncoiler body R is replaced with a new one, and the sending edge portion of the uncoiler body R is reset.

[0005]

[Problems to be solved by the device]

 However, when exchanging the delivery from the uncoiler body R, when a new material W to be transported is delivered, if it is guided as it is along the upper surface of the inclined guide device, the treatment device (41) continuous to the guide device It is not inserted between a pair of upper and lower pinch rollers arranged at the start end, but jumps above the pinch rollers. Therefore, conventionally, since the delivery end edge of the delivered member W has been manually pushed down and forcedly inserted between the pinch rollers, the manual work is extremely troublesome. However, it was a hindrance to automation of work.

On the other hand, prior to the delivery of a new transported member W, it is necessary to rewind another transported member W that has been delivered. However, in this rewinding, the rewinding speed is different from the sending speed, and the moving speeds of the left and right side edges of the transported member W are slightly different due to various obstacles and irregularities on the transport line. , It is practically impossible to be rewound in situ. Therefore, as a result of unwinding, loosening, etc. occurring in the transported member W of the unwinder body R that has been rewound, when sending this again, the sending position must be corrected on the carrying line, which is extremely troublesome. It was

That is, if the left and right sides of the transported member W do not move evenly due to obstacles, irregularities, and the like on the transport line, and if the rewinding speed is gradual, the uncoiler body R may be unrolled or loosened. It is considered that the winding deviation, the loosening, etc. are caused by the rewinding speed of the transported member W at the time of rewinding, and the nonuniformity of the suppression of the transported transported member W being unwound. In order to solve this, if the braking means for automatically controlling the transported member W is realized, detection of winding deviation, loosening, etc. and the amount of restraint by the braking means corresponding to this detection must be balanced. The control is extremely troublesome and complicated mechanically.

Therefore, the present invention has been devised in view of the existing circumstances as described above. For example, a long coiled member to be conveyed in a plurality of juxtaposed uncoilers is selectively replaced. When sending out and transporting the workpiece, the sending edge can be automatically loaded into the starting end of the processing machine, and when rewinding unnecessary transported members, tension is automatically applied to rewind. It is an object of the present invention to provide a feeding guide device for a long material capable of preventing winding deviation, loosening and the like that sometimes occur.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a long member W to be conveyed is selected from each of an appropriate number of uncoiler bodies R which are wound in a roll shape, and the predetermined member on the conveyance line is selected. A feed-in roller section 11 for feeding and guiding the conveyed member W fed out from the uncoiler body R to the processing processor (41), and a pivoting means 21 for the carry-in roller section 11 to the carry-in roller section 11. And the rear part of the uncoiler body R and the guided member 25, whose front part is swingably connected to the predetermined processing machine 41 side, and the conveyed member W fed from below the uncoiler body R, are substantially linear processing machines. The guide base 25 is inclined so as to be inserted into the (41) side, and the elevating means 31 having a cushioning action for elevating the rear part of the guide base 25 so as to position the guide base 25 substantially horizontally. It is characterized by

The elevating means 31 is an air cylinder, and the carry-in roller portion 11 is arranged in a row on each guide bar 13 in which a plurality of guide rollers 12 protruding on the upper surface are arranged at appropriate intervals in parallel in the feed direction. Can be configured.

The guide base 25 is provided with a proper number of pressing guide rollers 27 substantially orthogonal to the feed direction on a guide base plate 26 that is pivotally connected to the processing machine (41) side and has guides on both sides. The piece 28 can be provided upright.

[0012]

[Action]

 In the long material feeding device according to the present invention, the uncoiler body R feeds the transported member W by being rotated in the feeding direction, or is rotated in the rewinding direction which is the opposite direction. The conveyed member W is rewound.

Expansion and contraction of the elevating means 31 raises and lowers the rear part of the guide table 25, and when the guide table 25 is contracted and lowered, the guide table 25 itself is tilted, so that the transported member W sent out from under the uncoiler body R is conveyed. Is sent linearly to the pinch roller 35 on the side of the processing machine (41) and is pinched.

Further, when the guide table 25 itself is extended and positioned horizontally, a step is formed between the rear end of the guide table 25 and the front end of the uncoiler portion, and the step of the lifting means 31 itself interferes with the step. Further, if there is a deviation in the feeding direction, the rear part of the guide base 25 is bent so as to eliminate this deviation, and a tension action of moving up and down is exerted. Therefore, the shift is corrected and the transported member W is sent to the correct position.

Further, when the transported member W is rewound from the processing processor 41 side, the lifting means 31 buffers unevenness on the left and right, abruptness, and the like that occur at the time of rewinding. However, when pulling back lightly and rewinding, tension such as stretching is automatically applied to prevent misalignment and loosening that occur during rewinding.

【Example】

 BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 shown in the drawings is an installation base having a conveying surface 2 on which a large number of freely rotating conveying rollers, rollers and the like are appropriately arranged. On this installation base 1, an appropriate number of, for example, 5 uncoiler bases 3 are provided with a step along the feeding and conveying direction of the member W to be conveyed, which is a long coil-shaped plate material. (See FIG. 3). On the uncoiler base 3, driving rollers 4 before and after the uncoiler body R, in which the transported member W is wound in a roll shape, are mounted between the uncoiler bases 3 are rotatably arranged. At least one of them is driven and rotated by the drive motor 5 so as to rotate the uncoiler body R itself by abutting on the peripheral edge.

In the uncoiler body R mounted and supported by the front and rear drive rollers 4, the outer peripheral edge position in the maximum diameter of the transported member W to be sent by this is set higher than the upper surface of the uncoiler base 3. It is as a thing.

The uncoiler base 3 shown in the figure is framed by a rectangular tubular steel material in a cross section arranged on the left, right, front and back so as to have a substantially rectangular shape in a plane. It has a reinforced structure that can sufficiently support the load of the transported member W being wound. The uncoiler base 3 itself is supported and placed on the installation base 1 so as to be freely movable back and forth and left and right with a plurality of free bearing bodies 6 fixed to the upper surface of the installation base 1. By doing so, it is possible to automatically correct winding deviation and the like when the transported member W is unwound.

Further, as shown in the figure, the installation base 1 itself has a step structure in which the front is high in the sending direction and the rear is low, and each of the step parts supports one uncoiler base 3 respectively. , The transport surfaces 2 of the transported members W that are respectively sent out are arranged and formed in the installation base 1 in the up-down direction, and join with the carry-in roller section 11 which is the main line of transport to various processing machines (41). There is something to do. For this reason, for example, when the transported member W is rewound when the transported member W is replaced, the rewinding position may be up to the confluence with the transport main line, and unnecessary rewinding work can be saved. It is possible to improve efficiency.

Between the uncoiler section provided with the appropriate number of uncoiler bodies R and the side of various processing machines (41) for performing a predetermined process on the transported member W sent from the uncoiler section. The device guide device 10 including the carry-in roller portion 11, the guide table 25, and the elevating means 31 is disposed in the interior of the device.

The carry-in roller portion 11 is for placing and guiding the transported member W fed from the uncoiler body R, and a plurality of guide rollers 12 projecting on the upper surface are arranged in parallel in the feeding direction at appropriate intervals. The guide bars 13 are arranged in a row, and the rear ends of the guide bars 13 are swingably connected to slide bars 18 which are laterally arranged between the left and right slide means 14 formed on the inner surfaces of both side walls of the installation base 1, The front end of the guide bar 13 is connected to a pivoting means 21 which is swingably connected to the rear end of the guide base 25.

The slide means 14 has a slide rod 16 installed between fixed blocks 15 fixed to the front and rear of the inner surface of the side wall of the installation base 1, and a slide block 17 is slidably fitted to the slide rod 16. In addition, the slide bar 18 is laterally provided between the left and right slide blocks 17. The slide means 14 automatically adjusts the rear end position of the carry-in roller portion 11 caused by tilting movement and horizontal movement of the guide base 25, which will be described later, and ensures a smooth undulating operation of the guide base 25.

The pivotal support means 21 is composed of a left and right bearing portions 22 projecting from the rear end of the guide base 25, and swingably supports a connecting bar 23 having a substantially U shape in a plane, and the connecting bar 23 guides the connecting bar 23. The front end of each of 13 is connected.

As described above, the guide bar 13 of the carry-in roller unit 11 has the delivery end edges of the transported members W delivered from the respective uncoiler bodies R and arrives at the guide table 25 on the guide roller. The respective conveyed members W are merged so as to be moved to the side.

In addition, the guide table 25 has a substantially rectangular shape in a plane in which the transported member W to be delivered is conveyed, and is mounted on a guide base plate 26 whose front end is pivotally connected to the processing machine (41) side. A suitable number of pressing guide rollers 27 that are substantially orthogonal to each other are arranged, and guide pieces 28 are erected on both sides. Further, a guide roller 29 is rotatably mounted between the left and right bearing portions projecting from the rear end of the guide board 26 so that the conveyed target member W can be conveyed smoothly.

In the guide table 25, the front end portion of the guide base plate 26 corresponds to the position of the pinch roller 35 on the processing machine (41) side, and the rear portion of the guide base plate 26 is inclined downwardly to convey the member to be conveyed. When W is fed, care is taken so that the feeding edge of the transported member W reaches the position of the pinch roller 35 as it is.

The elevating means 31 has an air cylinder structure arranged on the installation base 1 below the guide table 25 itself. The rear part of the cylinder case is on the installation base 1 and the tip of the cylinder rod is the guide base. The rear lower surfaces of the 26 are connected to each other so as to be swingable. When the feeding end edge of the transported member W starts to be fed out from below the uncoiler body R, the size of the transported member W is reduced, and the guided base 26 is inclined to make the transported member W substantially straight. ), And when the positioning of the sending-out edge on the processing machine (41) side is completed, it is extended during processing and when the transported member W is rewound, and the guide base 26 is almost extended. It is positioned horizontally, and a step is formed between the rear end of the guide table 25 and the front end of the uncoiler portion.

In the present embodiment, there are three air cylinders arranged at each of the left and right sides and the central position in the feeding direction of the transported member W, but it is not limited to this. Further, instead of the air cylinder, a hydraulic cylinder having an elastic body such as a spring may be used.

Reference numeral 32 in the drawing is a stopper for setting the lowest level position when the rear portion of the guide base 26 is lowered, and is formed in the shape of an upright bar having an upper surface with which the rear bottom surface of the guide base 26 abuts.

Next, as an example of the use thereof, as shown in FIG. 3, an uncoiler body R in which various materials to be conveyed W, which are long plate materials, are rolled and held in a roll shape, is shown. , Set and set it on the uncoiler base 3 on the installation base 1 so that a step is set and juxtaposed along the transport direction. Then, it is sent out so as to perform die cutting with a predetermined processing machine in front of the transfer line, for example, a plasma cutting machine 41 or the like. The pinch roller 35, the length measuring device 43, the inkjet printer 44, the shear 45, the conveyor 46, etc. After that, it is sent to the plasma cutting machine 41.

At the time of this sending out, by exchanging the material or sending out from another new uncoiler body R after consumption, when the transported member W in each uncoiler body R is selected, When the conveying member W is sent out, the elevating means 31 is contracted and the rear part of the guide base 25 is lowered to guide it on the guide base 26. Insert it in the pinch roller 35 of. After that, the elevating means 31 is extended, the guide table 25 itself is made horizontal, and the transported member W is sent out in the same manner as in the conventional case. At this time, if there is a deviation of the normal position with respect to the feeding direction, the bending accompanying the deviation is generated in the step portion, that is, in the step portion generated between the rear end of the guide table 25 and the front end of the uncoiler portion. Therefore, the flexure itself independently occurs in the upper and lower parts of the stepped portion in the left and right parts of the transported member W, and the flexure amount corresponds to the correction amount. It can be done automatically or manually from the left, right, top and bottom directions.

Further, when the transported member W that has been sent out until then is rewound from the processing machine (41) side, when the uncoiler body R that is rotated in the unwinding direction winds up the transported member W, If the left and right sides of the transported member W do not move evenly due to obstacles, irregularities, etc. on the transport line, and if there is gradual movement during rewinding, the lifting means 31 of the air cylinder structure exerts an automatic cushioning effect. When pulling strongly and rewinding, it is reduced, and when pulling weakly and rewinding, tension is automatically applied to prevent it from slipping or loosening that occurs during rewinding.

[0033]

[Effect of device]

 The present invention is configured as described above, and therefore, when selectively exchanging the transported member W which is a long plate material in a plurality of juxtaposed uncoiler bodies R, the sending edge portion is processed. The starting end on the machine (41) side can be automatically loaded without requiring human labor, and the tension that is automatically given when the unnecessary conveyed member W is rewound causes the winding to occur at the time of rewinding. It prevents slipping and loosening, and can be properly rewound to the original position.

That is, this is the carrying-in roller portion 11 for placing and guiding the member W to be conveyed from the uncoiler body R, and the rear portion of the carrying-in roller portion 11 on the side of a predetermined processing machine (41) in the present invention. A guide base 25 whose front parts are connected to each other in a swingable manner, and an elevating means 31 having a cushioning action for elevating the rear part of the guide base 25 so as to position the guide base 25 in a tilted or substantially horizontal manner. This is because it is provided with the automatic loading setting of the conveyed member W to the processing machine (41) side at the start of feeding, and the conveyed member W by the automatic tensioning. Therefore, it is possible to correct the conveyance direction, and prevent winding deviation and loosening at the time of rewinding.

The elevating means 31 elevates and lowers the rear part of the guide base 25 to select the inclination or horizontal state of the guide base 25 itself. Compared with the control required, the mechanism is not only extremely simple, but also operates reliably and is easy to maintain.
