Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying a corrugated machine with a roll base paper obtained by winding a long base paper such as a corrugated board into a roll.

[0002]

2. Description of the Related Art A corrugating machine is used for pulling out a long base paper at any time from a roll base paper obtained by winding a long base paper in a roll shape, and has been conventionally used in a production line for corrugated cardboard boxes and the like. .

Specifically, the corrugating machine is provided with a mill roll stand device for holding the roll base paper rotatably around its axis at the center thereof, and this mill roll stand device has a width of the roll base paper. The rolling centers provided at the tips of a pair of open / close arms that can be opened / closed in each direction are inserted into the paper tube forming the central axis of the roll base paper from both ends, and the roll base paper is rotated between the open / close arms. I try to hold it freely. Then, the corrugating machine is adapted to pull out a long base paper from the roll base paper at any time while rotating the roll base paper rotatably held by the mill roll stand device.

On the other hand, as an apparatus for supplying the roll raw paper to the corrugating machine, for example, the roll raw paper is placed on a conveying jig which is moved toward the corrugating machine by a chain drive on a rail laid toward the corrugating machine. It is known that the roll base paper is supported in this support state in the width direction together with the transfer jig toward the corrugating machine and supplied to the corrugating machine.

In this case, the opening / closing arm of the corrugating machine can normally hold the corrugating machine correctly at a position where the machine center of the corrugating machine and the center of the roll raw paper in the width direction coincide with each other. Therefore, in the conventional feeder, when the roll base paper is supported on the transport jig, the roll base paper is placed on the transport jig so that the center of the roll base paper and the center of the transport jig are substantially aligned with each other. On the other hand, when the carrier jig supporting the roll base paper is moved toward the corrugating machine, the moving position of the carrier jig is detected and the center of the carrying jig is aligned with the machine center of the corrugating machine. The carrying jig is moved together with the roll base paper to a position where the center of the roll base paper on the carrying jig and the machine center of the corrugating machine are substantially aligned. It had to be.

However, in such a feeding device, the transport jig merely supports the roll base paper and the roll base paper is relatively large. It is difficult to support the transfer jig on the transfer jig at a position where the center of the transfer jig and the center of the transfer jig are coincident with each other. Therefore, the center of the roll base paper and the center of the transfer jig may be relatively displaced. There were many. If the roll base paper and the transport jig are displaced in this way, the positional displacement between the center of the roll base paper and the machine center of the corrugated machine also becomes relatively large. There is a possibility that the holding of the roll base paper by the open / close arm may become uncertain.

In order to solve such inconvenience, for example, it is conceivable to provide the carrying jig with a positioning means for positioning the roll base paper at a predetermined position. Such a positioning means is provided on the carrying jig. Then, the structure of the carrying jig becomes large, and it is disadvantageous in terms of cost. In particular, when the roll base paper having various widths is supplied to the corrugating machine, there is a disadvantage that the configuration of the positioning means becomes complicated.

[0008]

DISCLOSURE OF THE INVENTION The present invention eliminates such inconveniences and, when feeding a roll base paper to a corrugating machine, surely aligns the center of the roll base paper in the width direction with the machine center of the corrugating machine. It is an object of the present invention to provide a roll base paper supply device capable of achieving the above-mentioned structure and having a simple structure.

[0009]

In order to achieve such an object, the present invention provides a roll base paper obtained by winding a long base paper in a roll shape up to a position where the center in the width direction and the machine center of a corrugating machine coincide with each other. An apparatus for supplying to the corrugating machine, which is provided with a conveying path extending toward the corrugating machine and movably toward the corrugating machine in the conveying path, and conveys the roll base paper with the axis center thereof. A conveying jig that supports in the extending direction of the path, a moving means that moves the conveying jig that supports the roll base paper toward the corrugating machine, and a machine center of the corrugating machine at an intermediate position of the conveying path. The roll base paper, which is provided at a predetermined position with a predetermined space between and is supported by the transport jig, is transported toward the corrugating machine by the moving means. The roll base paper, at least one of the front end of the roll base paper reaching the predetermined position and the rear end of the roll base paper reaching the predetermined position is detected. From the time when the leading edge of the roll base paper is detected to reach the predetermined position by the detection means at the time of conveyance, only a moving distance obtained by adding a half of the width of the roll base paper to the predetermined interval, or After the detection means detects that the rear end of the roll base paper has reached the predetermined position, the conveyance jig is moved by a moving distance obtained by subtracting a half of the width of the roll base paper from the predetermined interval. And a control means for controlling the moving means to move toward the corrugating machine.

Further, the detection means both the fact that the leading end of the roll raw paper supported by the conveying jig has reached the predetermined position and that the rear end of the roll raw paper has reached the predetermined position. Detecting means for detecting the fact that the leading end of the roll base paper supported by the transport jig has reached the predetermined position from the time when the detection means detects the end of the roll base paper. Measuring means for measuring the width of the roll base paper by measuring the amount of movement of the conveying jig until the detection means detects that the end portion has reached the predetermined position, and the measuring means And a calculating means for calculating the moving distance based on the width of the rolled roll paper.

[0011]

According to the present invention, when the roll base paper is supplied to the corrugating machine, the roll base paper is supported on the transport jig, and in this state, the transport jig moves the roll jig. The roll base paper is moved toward the corrugating machine together with the roll base paper, and the roll base paper is conveyed and supplied to the corrugating machine. At this time, during the conveyance, the detection means detects that the leading end of the roll raw paper has reached the predetermined position or that the rear end of the roll raw paper has reached the predetermined position.

When the detection means detects that the leading end of the roll raw paper has reached the predetermined position, the movement means is controlled by the control means. , When the leading end of the roll base paper reaches the predetermined position, move the transport jig together with the roll base paper toward the corrugating machine by a moving distance obtained by adding a half value of the width of the roll base paper to the predetermined interval. By this, the roll base paper is fed to a position where the center thereof coincides with the machine center of the corrugating machine. this is,
At a position where the center of the roll base paper and the machine center of the corrugated machine coincide with each other, the distance between the leading end of the roll base paper and the predetermined position is equal to a value obtained by adding half the width of the roll base paper to the predetermined distance. Because.

On the other hand, when the detecting means detects that the rear end of the roll base paper has reached the predetermined position, the moving means controls the rear end of the roll base paper by the control of the control means. When the predetermined position is reached, the transport jig is moved together with the roll base paper toward the corrugating machine by a moving distance obtained by subtracting a half value of the width of the roll base paper from the predetermined interval, whereby the roll base paper is moved. The center of the corrugated machine is fed to the machine center. This means that at the position where the center of the roll base paper and the machine center of the corrugating machine coincide with each other, the distance between the rear end of the roll base paper and the predetermined position is a value obtained by subtracting half the width of the roll base paper from the predetermined interval. Because it is equal to the value

Furthermore, both the detection means means that the leading end of the roll raw paper supported by the conveying jig has reached the predetermined position and that the rear end of the roll raw paper has reached the predetermined position. When the control means is provided with the measuring means and the computing means, the measuring means causes the leading end portion of the roll base paper in response to the detection by the detecting means when the roll base paper is conveyed. The width of the roll base paper is measured by the moving amount of the transport jig from when the sheet reaches the predetermined position to when the rear end of the roll base paper reaches the predetermined position. This is because the movement amount is equal to the width of the roll base paper.

Then, the calculating means obtains the moving distance based on the measured value of the width of the roll base paper, and the controlling means controls the moving means as described above based on the calculated value of the moving distance. To do.

At this time, the transport jig 4 is pulled to the downstream side of the transport path 1 via the wire 14b and moves toward the corrugating machine 7.

Contrary to the above, when the winch 13 is rotated counterclockwise as shown in FIG.
While the wire a is wound around the winch 13, the wire 14b is pulled out from the winch 13, and at this time, the transport jig 4 is pulled to the upstream side of the transport path 1 via the wire 14a and the upstream end portion of the transport path 1 is pulled. Move towards.

Then, the moving means 5 causes the drive motor 15 to rotate the winch 13 in the clockwise or counterclockwise direction as described above, thereby causing the wire 14 to move.
The transport jig 4 is moved in the transport path 1 via a and 14b.

In FIG. 1, when the roll base paper W supported by the transport jig 4 is transported from the upstream side to the downstream side of the transport path 1 as described above, the detection means 8 rolls the roll base paper W. It detects that the front end of the roll has reached the detection position P and that the rear end of the roll base paper W has reached the detection position P, and stands on the base 2 at the detection position P. The above detection is performed photoelectrically through a sensor 23 (see FIG. 4) such as a photoelectric switch fixed to the support 22 provided.

The control means 6 includes a control main body portion 24 having a control circuit portion 23 including a CPU (not shown) and the like inside,
Rotary encoder 25 connected to the winch 13
The control circuit section 23 is electrically connected to the sensor 23 of the detecting means 8, the drive motor 15 of the moving means 5 and the rotary encoder 25, while the width of the roll base paper W is detected via the detecting means 8. measuring means 26 for measuring t,
The width t of the roll base paper W measured by the measuring means 26
And a calculation means 27 for performing a calculation to be described later.

In this case, the rotary encoder 25 is fixedly installed on the base 2 at the lateral position of the winch 13, and the driven gear 28 attached to the input shaft 25a thereof is inserted into the end portion of the winch 13. The drive gear 29 attached to the chain 3
When the input shaft 15a is rotated with the rotation of the winch 13 by this connection, the winch 1
3 every predetermined rotation angle, in other words, the winch 13
A pulse is output to the control circuit unit 23 for each predetermined movement amount of the transfer jig 4 that is moved via the wires 14a and 14b in accordance with the rotation of the.

Then, the control circuit section 23 counts the pulses received from the rotary encoder 25 to obtain the movement amount of the carrying jig 4, and further, the position of the machine center C of the corrugating machine 7, which is inputted in advance, The moving position of the conveying jig 4 is obtained based on the detection position P, the position of the loading station X, the position of the payout station Y, and the like, and the movement is performed based on the calculation result of the calculating means 27 described below and the like. The means 5 is controlled.

The measuring means 26 of the control circuit section 23 is
When the roll base paper W supported by the transport jig 4 is transported from the upstream side of the transport path 1 toward the corrugated machine 7,
The detection means 8 detects that the trailing end of the roll base paper W has reached the detection position P since the detection means 8 detected that the leading end of the roll base paper W has reached the detection position P.
The amount of movement of the transport jig 4 up to the time detected by is measured according to the output signal of the sensor 23 of the detection means 8, and the width t of the roll base paper W is measured by this.

That is, in this case, clearly from FIG.
The above-described movement amount of the transport jig 4 in this measurement is equal to the width t of the roll base paper W, and therefore the width t of the roll base paper W is measured by the movement amount.

At the time of carrying the roll base paper W as described above, the calculating means 27 moves the carrying jig 4 toward the corrugating machine 7 from the time when the rear end of the roll base paper W reaches the detection position P to the roll base paper. A movement amount to be moved together with W (hereinafter, referred to as a calculated movement amount) is calculated, and the calculation is performed by a predetermined distance D between the machine center C of the corrugated machine 7 and the detection position P (this distance D is set in advance). (Input to the control circuit unit 23) and the width t of the roll base paper W measured by the measuring means 26, according to the following equation (1).

That is, assuming that the calculated movement amount is x, x = D-t / 2 (1) Then, the control circuit section 23 controls the moving means 5 to detect the rear end of the roll base paper W. From the time when the position P is reached, the transfer jig 4 is moved by the calculated movement amount x obtained by the equation (1).
Is moved toward the corrugated machine 7.

With this arrangement, it is apparent from FIG. 1 that after the movement, the trailing end of the roll base paper W is moved from the machine center C of the corrugating machine 7 to the upstream side of the conveying path 1 by the distance t /.
Since the roll base paper W is located at a position separated by two, the center of the roll base paper W in the width direction and the machine center C coincide.

Next, the overall operation of such a feeding device is shown in FIG.
Follow the instructions below. Roll base paper W to corrugate machine 7
When feeding the roll base paper W to the feeding jig 4 with the feeding jig 4 stopped at the feeding station X, the roll base paper W is fed onto the feeding jig 4 by the feeding device (not shown). The roll base paper W is supported on the transport jig 4.
At this time, the roll base paper W is supported at the approximate center of the transport jig 4, but the center of the roll base paper W in the width direction and the center of the transport jig 4 do not always coincide.

Then, under the control of the control means 6, the drive motor 15 of the moving means 5 rotates the winch 13 in the clockwise direction, whereby the transport jig 4 transports the roll base paper W together with the roll base paper W as described above. The roll base paper W is moved toward the downstream side of the path 1 and conveyed toward the corrugating machine 7.

When the leading end of the roll base paper W reaches the detection position P during this conveyance, this is detected by the detection means 8, and at the same time as this detection, the measurement means 26 of the control means 6 causes the conveyance jig W to move. The measurement of the movement amount of is started.

When the roll base paper W is further conveyed and its rear end reaches the detection position P, the detection means 8
Is detected, and at the same time as this detection, the above-mentioned measurement by the measuring means 26 is terminated. At this time, the movement amount of the transport jig 4 measured by the measuring means 26 from the start to the end of the measurement is the width t of the roll base paper W as described above,
Thereby, the width t of the roll base paper W is measured.

Then, when the width t of the roll base paper W is measured in this way, the calculating means 27 immediately executes the above (1).
The calculated movement amount x is calculated according to the formula, and the control means 6
Controls the moving means 5 to move the transport jig 4 together with the roll base paper W toward the corrugating machine 7 by the calculated movement amount x from when the rear end of the roll base paper W reaches the detection position P. After the movement, the transfer jig 4 is stopped.

At this time, as described above, the conveying jig 4 is stopped at the position where the center of the roll base paper W and the machine center C of the corrugating machine 7 coincide with each other.

Then, in this state, the corrugating machine 7 rotatably grips the paper tube a (see FIG. 4) of the roll base paper W by the opening / closing arms 7a, 7a, and conveys the roll base paper W by a jig. 4, and the long base paper b (see FIG. 4) is pulled out at any time.

After all of the long base paper b has been pulled out from the roll base paper W, the corrugating machine 7 operates the paper core a.
Only the bearing is again supported on the transfer jig 4.

Then, under the control of the control means 6, the drive motor 15 of the moving means 5 rotates the winch 13 counterclockwise, contrary to the above-mentioned conveyance, whereby the conveyance jig is moved as described above. 4 is moved together with the paper tube a toward the upstream side of the transport path 1 to the payout station Y. Then, after the movement, at the payout station Y,
The paper tube a is dispensed from the transport jig 4 by a dispenser (not shown) or the like, and after that, the moving means 5 moves the transport jig 4 to the original position (feeding station X) under the control of the control means 6. return.

As described above, in this feeding device, the width t of the roll base paper W is measured by the measuring means 26 during the feeding to the corrugating machine 7, and various widths are obtained regardless of the size of the width t. The roll base paper W having t can be reliably supplied to a position where the center in the width direction and the machine center C of the corrugating machine 7 coincide with each other.

In this embodiment, the width t of the roll base paper W is measured by the measuring means 26 through the detecting means 8 in order to cope with the roll base paper W having various widths t. When the width t of W is determined to be one type, for example, if the width t is previously input to the control circuit unit 23 of the control means 7, even if the measurement of the width t is omitted, The calculation of the formula (1) can be performed by the calculating means 27, and therefore, the roll base paper W can be supplied to the corrugating machine 7 as in the present embodiment.

Then, in this case, it is apparent from FIG. 1 that when the leading end of the roll base paper W reaches the detection position P, the roll base paper W is moved together with the conveying jig 4 at a distance D + t / 2 (D).
It is also possible to make the machine center C and the center of the roll base paper W in the width direction coincide with each other by moving the machine center C toward the corrugating machine 7 by the distance between the machine center C and the detection position P. Of course.

[0052]

As is apparent from the above description, according to the present invention, when the roll base paper supported by the conveying jig in the conveying path is conveyed toward the corrugating machine by the moving means, it is detected during the conveyance. At least the leading end of the roll base paper has reached a predetermined position with a predetermined distance from the machine center of the corrugating machine, or the rear end of the roll base paper has reached the predetermined position. Is detected, and the moving means is controlled by the control means in response to the detection, and only the movement amount obtained by adding a half value of the width of the roll base paper to the predetermined interval from the time when the arrival of the leading end of the roll base paper is detected. Alternatively, the conveyance jig may be moved together with the roll base paper by an amount of movement obtained by subtracting a half of the width of the roll base paper from the predetermined interval after the arrival of the trailing end of the roll base paper. In by the it can be supplied to a position surely the roll fiberboard and the machine center and the center of the corrugating machine in the width direction match.

Further, in such a feeding device, the conveying jig may simply support the roll base paper, and the detecting means and control means which are the main constituent elements thereof can be simplified. The configuration of the entire supply device can be simplified.

The detection means performs both of the above-mentioned detections, and the width of the roll base paper is measured by measuring the movement amount of the conveying jig in the time interval between the both detections. Based on the measured width of the roll base paper, the amount of movement of the transport jig to the corrugating machine is obtained from the time of detection, so that the roll base paper having various widths can be reliably used. Can be supplied to a position where the center in the width direction and the machine center of the corrugated machine coincide with each other.
