Description

TECHNICAL FIELD The present invention relates to a turret type feeding device for packaging base paper, and is particularly large and heavy, such as a coil steel plate, and has a diameter and a surface length. The present invention relates to a turret type feeding device suitable for use in automatic packaging of cylinders having various sizes.

(B) Conventional technology Since a large and heavy packaged cylindrical body, for example, a coil steel plate, is a hollow cylindrical body, it is necessary to package all of the inner circumference, the outer circumference, and both end surfaces in order to completely package it. For the inner and outer wrapping, the width of the wrapping base paper must be changed according to the surface length of the cylindrical body.

Therefore, if coil steel sheets of various sizes are to be automatically packaged along one transportation line, many types of packaging base paper rolls must be prepared on this transportation line.

The apparatus conventionally developed by the present applicant as an apparatus for automatically packaging a large heavy article has an inner periphery packaging position, an outer periphery packaging position, an end face packaging position, and the like arranged in a vertical line along a linear transport line. In such a device, the inner or outer wrapping position is set at a fixed position on the transport line, and the packaging base paper must be supplied to this fixed position. Therefore, a large number of packaging base paper roll groups are stored in parallel in the ceiling space above the transport line along the transport line.

However, although such a ceiling storage method has the advantage that the individual base paper rolls are located above the cylindrical body to be wrapped and the centerlines of the widths of the base paper rolls can easily coincide with each other, a base paper roll with a considerable size and weight can be used in the ceiling space In addition to the large amount of work required to lift it up, the difficulty of installation and adjustment work at high places, and the relatively limited ceiling space, there was a problem that the number of base paper rolls that could be stored was limited.

Further, the packaging base paper pulled out from each roll is finally guided to the supply port at a predetermined position on the article to be packaged through each path. Since there is only one supply port, the connection between many paths and the supply port must be constantly switched, but the mechanism and operation of this switching are complicated, and all the base paper rolls are connected to one supply port. Since the lengths of the paths are not the same, the base paper web drawn from a distant base paper roll may slacken or shift in the middle, delaying the response to the switching operation, and always maintaining the required amount of base paper to be delivered accurately. There are difficulties such as not being able to do it.

Therefore, in the patent application relating to Japanese Patent Application No. 58-252130, the applicant of the present application stated that "the bearing is rotatably supported along the circumference of an annular body supported so as to be rotatable in a vertical plane. A plurality of base paper supply sources, each of which is composed of a single base paper roll, a feed roll that draws the base paper web from the base paper roll, and a guide plate that guides the drawn base paper web to the outer circumference of the torus, are installed. A web discharge position is provided at a constant height along the outer circumference of the body, and the guide plate of any one supply source is aligned with the discharge position by the rotation of the torus so that any base paper web can be discharged. Turret type feeding device. "

However, this device is inconvenient to replace the base paper roll.

(C) Problems to be Solved by the Invention The problems to be solved by the present invention are to improve the structure of the device disclosed in the above-mentioned patent application of the present applicant to facilitate the replacement of the base paper roll and to make the base paper. It is to obtain a turret type base paper supply device that can measure the supply amount of paper.

(D) Means for Solving the Problems The turret type base paper feeding device of the present invention comprises a pair of discs that are parallel to each other and have a predetermined interval, and a pair of discs that are arranged between the discs and surround the discs. A base paper supply unit consisting of a base paper roll, a feed roll, and a guide roll mounted along the base, a support roll that vertically rotatably supports the disc and a center of the pair of discs. A first drive motor that is connected to a central shaft that is connected to the drive roll and that drives the disc to rotate, and a second drive motor that selectively connects the feed roll to the drive shaft so that the feed roll rotates. And a measurement mechanism for selectively connecting to the feed roll so as to be detachable, and measuring the rotation speed of the feed roll.
The above problem is solved by means of a stopper mechanism that holds the disc at a predetermined angular position.

(E) Example A turret type base paper supply device of the present invention will be described with reference to FIGS. 1 to 6. This apparatus is composed of a pair of discs 1, a base paper supply unit 2, a support roll 3, a first drive motor 4, a second drive motor 5, a measuring mechanism 6, and a stopper mechanism 7.

The pair of discs 1 are fixed to the central shaft 11 in parallel with each other with a predetermined gap. The disc 1 is a fourth disc to reduce the weight.
As shown in the figure, it may be shaped like a wheel.

The base paper supply unit 2 is composed of a base paper roll 21, feed rolls 22 and 22, and a guide roll 23. Each element is supported by the disc 1 so that the disc 1 can be rotated. Unit 2
Are provided along the circumference of the disc 1. In each unit 2, the base paper P is unwound from the base paper roll 21, passes through a guide roll 23, and is pinched by a pair of feed rolls 22.

The support rolls 3 are provided in pairs at intervals of the disc 1.
The support roll 3 is rotatably supported by the bearing 31. The support roll 3 vertically supports a disk to support the disk in a rotatable manner.

The support roll 3 is the weight of the entire apparatus and the disk 1 described later.
Depending on the structure of the drive mechanism of the above, either pair of rolls (for example, the right or left roll in FIG. 2)
Can be omitted.

The first drive motor 4 and the second drive motor 5 are fixed on a support 8 as best shown in FIG. Central axis
One end of 11 is rotatably supported by the bearing stand 9, and the other end of the central shaft 11 is connected to the first drive motor 4. When the first drive motor 4 operates, the central shaft 11 is rotated, and as a result, the disc 1 is rotated.

The second drive motor 5 is fixed to a slide base 51 that slides on the support base 8, as shown in FIG. The slide base 51 is moved forward and backward by the fluid pressure cylinder 52.

One of the pair of feed rolls 22 is the drive roll. As shown in FIG. 5, a coupling 221 is attached to one end of the central axis of the feed roll 22. Disk 1
Is rotated and reaches the position of the second drive motor 5, it is stopped by the stopper mechanism 7 described later. The second drive motor 5 is moved forward, and the coupling 53 attached to the tip of the output shaft frictionally engages with the coupling 221.

As shown in FIG. 5, a measuring mechanism 6 is provided so as to face the second drive motor 5 with the disc 1 interposed therebetween. Counting mechanism 6
Is composed of a counter 61, a slide table 62, and a fluid pressure cylinder 63. The slide base 62 is movably supported on the bearing base 9 and is moved forward and backward by the fluid pressure cylinder 63. The counter 61 is fixed to the slide table 62.

The other end of the central axis of the feed roll 22 (coupling 221
A coupling ring 222 is attached to the opposite side). A coupling 611 is attached to the input shaft of the counter 61. When the couplings 53 and 221 at one end are engaged,
The couplings 611 and 222 at the other end are set to engage with each other. That is, the feed roll 22 is the second drive motor 5
When driven by, the counter 61 counts the number of rotations or the feed amount. The counter 61 may be connected to the drive shaft of the second drive motor 5.

The second drive motor 5 and the counter 61 may be attached to all of the drive-side feed rolls 22. In that case, when the feed roll 22 reaches a predetermined angular position, the required second drive motor 5 and counter 61 are set to selectively operate.

A stopper mechanism 7 is provided for stopping the disc 1 at a predetermined angular position with a predetermined pitch. For example, as shown in FIG. 6, a hole 12 is provided in the disc 1 corresponding to the circumferential pitch of the feed roll 22, and the tip 72 of the piston rod of the fluid pressure cylinder 71 is selectively engaged with the hole 12. It is certain that it can be removed. Instead of the stopper mechanism 7, the position detector and the first drive motor can be electrically controlled to control the position at a predetermined pitch.

Returning to FIG. 1 again, the desired base paper P is taken out from the base paper take-out position A and cut by a cutter C for each required length.

(F) Action The turret type base paper supply device of the present invention determines the roll of the base paper to be supplied according to the request from the end use place as described above, and the specific roll, for example, 21-1 is taken out from the base paper take-out position A The disk 1 is rotated by the first drive motor 4 so as to be moved to. The disk 1 is made by the stopper mechanism 7.
Hold in that position.

Then, the coupling 53 of the second drive motor 5 engages with the coupling 221 of the feed roll 22-1 to drive the feed roll. At the same time, the coupling 611 of the counter 61 engages the coupling 222 of the feed roll 22-1. As a result, the feed roll 22-1 is rotationally driven, and the amount of rotation is measured by the counter 61.

The feed roll 22-1 is rotated by a predetermined amount, a required length of the base paper P is fed from the base paper roll 21-1, and is guided to the outside of the disc 1 through the guide roll 23-1. If the relay body as described above is waiting there, for example, the front end of the raw paper P fed out is temporarily wound around a temporary winding roll of the relay body,
The rear end of the base paper P may be cut with the cutter C to a predetermined length. At the time of disconnection, it is decided based on the display of the counter 61.

(G) Effect According to the present invention, for many base paper supply sources, the path from the base paper roll to the base paper ejection port A is relatively short, and
Since it has the same length and a feed roll is always provided for each path of such a short length, it is possible to reliably and reliably supply the required length of packaging base paper from any base paper roll. . Therefore, it is optimal as a base paper supply source for the automatic packaging process.

Further, since the supply device of the present invention is a turret type that can rotate in a vertical plane, it requires less installation space, and is far more versatile than a flat arrangement such as a ceiling storage type. The base paper roll can be stored without difficulty.

The device of the present invention is stable because the lower peripheral portion of the disc is supported by the support roller and the center axis of the disc is supported by the bearing stand, and the front side received by the support roller is open. Therefore, operations such as the roll of the base paper, the passage of the web, and the adjustment of the equipment are very easy and safe.

Furthermore, unlike the ceiling storage system, the turret is installed on the floor, so if necessary, multiple pairs of disks can be installed side by side, and the base paper supply source can be expanded without reworking the packaging line itself. By diversifying, the processing capacity of the packaging line itself can be enhanced and improved.
