Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a corrugated cardboard stacking number counting device, and more particularly to a corrugated cardboard stacking number counting device capable of easily and accurately measuring.

2. Description of the Related Art Corrugated board is manufactured by attaching a liner to one or both sides of a corrugated corrugated core, cutting it to a predetermined size according to demand, and stacking a predetermined number of sheets with a palletizer or the like before shipping.

As a method of counting the number of stacked corrugated cardboard, it is performed based on the number of operations of the palletizer at the time of palletizing, or is measured by an operator.

However, in the former palletizer-based measurement method, when the two corrugated cardboards are attached together or when the corrugated cardboards are empty, the count number is incorrect.

Further, in the latter manual counting method, since a huge number is counted, there are many miscounts due to fatigue and the reliability is low.

Therefore, a counting device that mechanically counts the number of corrugated cardboards has been proposed, but if the corrugated cardboard sheet is warped or distorted, it may not be possible to count accurately without correcting the distortion or the like. , It was photographed and image processed, and it was expensive and impractical.

Means for Solving the Problems The present invention has been made in view of the above points, and in a corrugated cardboard stacking number counting device for measuring the number of palletized corrugated cards in a corrugated corrugated core, A corrugated cardboard liner and a plurality of objective sensors for detecting the presence or absence of the object of the central core are installed in the counting device within one wavelength of the corrugated shape of the central core. A processing unit is provided for turning on when the presence of the object is detected, and for turning off when at least one or more of the object sensors detect the existence of the object and do not detect that all of the objects exist at the same time. A predetermined number such as one sheet is subtracted from the count number that is turned OFF between ON and ON processed by the arithmetic processing unit, or the count number that is counted by ON, OFF, and ON Another object of the present invention is to provide a corrugated cardboard stacking number counting device characterized in that a counting unit is connected to an arithmetic processing unit so as to count the number of stacked layers according to the number of times.

According to the present invention, even if the corrugated cardboard is warped or distorted, a large amount of warp or warp is caused by the plurality of objective sensors installed within one wavelength of the corrugated corrugated core. As long as it is not distorted, the objective sensor can detect the corrugated liner and core accurately. Then, when the object is detected by scanning along the end face of the corrugated corrugated corrugated corrugated corrugated cardboard where the counting device is seen,
In the liner section on the front and back of the corrugated board, all the objective sensors are in the state of detecting at the same time, and since the center core is bent in a wave shape between the liner on the front and the back, all the objective sensors detect at the same time. It will not be possible. Therefore, for example, between ON and ON in which all the objective sensors detect the ON state at the same time, all the objective sensors are not turned ON, and at least one or more of them are in the detection state and the count number is OFF. The arithmetic processing unit performs arithmetic processing, and the counting unit connected to the arithmetic processing unit sequentially counts the number of stacked corrugated cardboard boxes.

Embodiment Hereinafter, the present invention will be described based on an embodiment.

FIG. 1 and the following are embodiments of the present invention. The counting device 1 for counting the number of stacked corrugated cardboards is formed as a portable handy scanner type, and as shown in FIGS. 1 and 2, a grip portion 3 is provided to project on a device main body 2 for detecting an object, and Rollers 4 for traveling are pivotally attached to both sides. As shown in FIGS. 2 and 3, a plurality of units (in FIG.
Object sensors 5 are arranged at predetermined intervals within one wavelength λ of the corrugated core 9 between the liners 7 and 8 on the front and back sides of the corrugated board 6 which are bent in a wave shape.

The objective sensor 5 is of a light sensor type such as a bar code reader, and each of them has a light projection unit 1 as shown in FIG.
A light beam such as a laser beam projected from 0 is focused by a focusing unit 11 and appropriately deflected by a deflecting unit 12 to irradiate the end face of the corrugated cardboard 6, and the reflected light is received by a light receiving unit 13 and amplified by an amplifying unit 14. The digital converting section 15 is configured to perform digital conversion and arithmetic processing.

In the arithmetic processing unit 16, the case where a plurality of all the objective sensors 5 detect the object is processed as ON, and the case where one or more objective sensors 5 detect the object and all the objects are not detected. It is processed as OFF. And
By connecting the counting unit 17 to the arithmetic processing unit 16, the arithmetic processing unit 1
If the OFF process is not performed between the ON and ON of 6, the gap is regarded as a gap and the counting process is performed without counting.
It is displayed on the display unit 18 so that it can be automatically counted. It is to be noted that the case where the arithmetic processing unit 16 is ON is counted, and the case where one objective sensor 5 is not detected between ON and ON is regarded as a gap, and 1 is subtracted from these count numbers. It is also possible to perform a counting process.

In this way, when the end surface of the corrugated cardboard 6 on which the counting devices 1 are stacked as shown in FIG. 1 is scanned, all the objective sensors 5 cover the liners 7 and 8 in the liners 7 and 8 as shown in FIG. At the same time, all of the objective sensors 5 cannot detect the core 9 at the same time in the corrugated core 9, but at least one objective sensor 5 detects it, and the number of corrugated cardboards 6 stacked is determined as described above. It is to count.

If the liner 7 is distorted as shown in FIG.
The object is detected as a gap of the corrugated cardboard 6 and can be processed without counting to accurately count the number of sheets.

As can be seen from the above, for the accuracy of the objective sensor of the counting device, it is preferable to install a plurality within the one wavelength of the core, and it is most preferable to install every quarter wavelength for the detection of the core. The sensitivity is good, but the error is large for the warp and distortion of the liner. Therefore, it is practically preferable to install the objective sensor at an interval of ⅛ wavelength to ¼ wavelength in the middle of these.

In the above hand scanner type counting device,
There may be problems with its scanning speed and reverse run, but with a tachometer connected via rollers pivotally mounted on both sides of the counter,
In the case of overspeed or in the case of reverse running, an alarm such as a buzzer sound can be issued to easily deal with it.

Further, although a problem may occur with respect to the tilt of the counting device during scanning, it is possible to appropriately deal with such a problem by installing a tilt sensor in the device and issuing an alarm when the counting device is tilted more than an allowable amount. If necessary, a vertical auxiliary tool for scanning such as a ruler may be arranged and the counting device may be scanned along the vertical auxiliary tool.

In the above embodiments, the portable counting device that can be manufactured at low cost and is easy to use has been described, but the counting device based on the above counting principle is fixedly installed on the side of the palletizer or the like and stacked. It is also possible to count the number of stacked corrugated boards by automatically facing the above-mentioned counting device against the end surface of the corrugated board and scanning it vertically.

In the example, the double-faced corrugated board with liners attached to both sides of the core was described, but the same applies to the single-sided corrugated board, the double-sided corrugated board, and the triwall corrugated board by appropriately modifying the counting method of the arithmetic processing unit. It is clear that it can be counted.

Further, in the above-mentioned embodiments, a plurality of objective sensors are installed in the counting device as a pair, but these pair of objects are arranged at predetermined intervals, preferably (N + 1/4) times (N is an integer value) of the center core. If you install multiple pairs, such as by providing for each wavelength interval,
In addition to the optical sensor, the objective sensor can be a sound wave sensor such as an instant camera or the like, which can further improve the counting accuracy of the number of stacked corrugated cardboard.

Effect of the Invention As described above, in the present invention, the presence or absence of the object is detected by installing a plurality of objective sensors within one wavelength of the bent wavelength of the core. When scanning the end surface of the corrugated cardboard where the counting devices are stacked, as long as the corrugated cardboard is not warped or distorted for an excessive amount, in the corrugated cardboard liner section, all of the objective sensors simultaneously detect the presence or absence of the liner. All of the objective sensors cannot detect the core at the same time in the corrugated core, but at least one objective sensor can detect the core. Then, the number of counts in which all of the objective sensors processed by the arithmetic processing unit are OFF between ON and ON for detecting the presence or absence of the object, or ON, OF
It is possible to easily and accurately count the number of stacked corrugated cardboards by subtracting a predetermined number such as 1 from the number of times counted with F and ON. It is not necessary to binarize this end face image, and the number of corrugated cardboards that are stacked can be accurately counted directly and easily.
