Abstract

PROBLEM TO BE SOLVED: To automatically count the number of glass plates when they are loaded by hand, by outputting a signal corresponding to the difference from the weight right before loading to a controller for a certain time when the glass plates are loaded, counting the number of glass plates loaded by comparing it with a previously inputted set value, and then resetting the weight of a weighing machine to zero. SOLUTION: Before the glass plates 1 are loaded, a palette 7 and a palette support frame 5 are weighed by the weighing machine 11. When a tare subtraction command is supplied to the controller 13, the weighing machine 11 resets a counted value corresponding to the weight of the palette 7 and palette support frame 5 to zero. A glass plate 11 is loaded on the palette 7 thereafter and the weight signal of the loaded glass plates 1 is outputted in a stable state to the controller 13 continuously for a certain time, e.g. 5 seconds, so that the weight is compared with the set value. Then when the weight is within a certain range, a counter addition signal is outputted to a counter 14 to reset the glass weight of the weighing machine 11 to zero, so that the weighing machine stands by for the loading of a next glass plate 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for automatically counting and counting the number of loaded sheets when loading glass sheets into containers such as pallets by hand.

[0002]

2. Description of the Related Art Conventionally, various methods and apparatuses for loading a plate-like body such as a glass plate into a container such as a pallet have been known. Loading is performed on a pallet or other container or table one by one by suction. In this case, a method and an apparatus for counting the number of loaded sheets by various operation signals are generally well known. Automation is technical,
When it is difficult due to cost or other circumstances, the loading operation is manually performed, and the number of loaded sheets is generally counted by an operator.

In addition, when loading is performed manually, there is a method of subtracting the weight of the container from the total weight of the loading and converting the number of sheets. Further, JP-A-4-177588 discloses that
A method of measuring the number of stacked plate materials is known in which light is applied to the side surfaces of the stacked plate materials, and the intensity waveform of the reflected light is subjected to Fourier transform processing and filtering, and the stack height is divided by the distance between the maximum spectral intensities. Have been.

[0004]

When a glass plate is manually loaded into a container such as a pallet without using an automatic machine such as a loading robot, when a worker counts and counts the number of loaded glass plates, a counting error easily occurs. The reliability of the counting accuracy is not good.

Further, when the weight of the container is subtracted from the total weight of the glass plates in which the glass plates are stacked and stacked on the pallet on the weighing machine and the number is converted into the number of glass plates, the number of the glass plates varies depending on the thickness of the glass plates. Due to the percentage error,
There was a problem that it was not possible to accurately grasp the number of sheets. For example, in the case of a glass plate having a thickness of 3.1 mm, there is a tolerance of ± 0.1 mm, which results in an error of ± 3.2%, and when 150 sheets are loaded, an error of ± 4 to 5 sheets occurs. become.

Further, Japanese Unexamined Patent Publication No. Hei 4-177588 discloses a method in which light is applied to the side surface of a loaded plate material and the intensity waveform of the reflected light is used. In order to prevent scratches from occurring between the sheets, the inserted slip sheet protrudes from the edge of the glass sheet, so even if light is irradiated on the side of the laminated glass sheet, the reflected light is scattered by the slip sheet. There was a problem that the waveform was disturbed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a method and apparatus for automatically counting and counting the number of loaded glass sheets when loading glass sheets into containers such as pallets by hand. A pallet support frame is attached, and containers such as pallets are placed on pallet supports provided at four corners of the pallet support frame.

When a tare instruction is issued while the pallet is placed on the weighing machine, the weighing machine resets the count value corresponding to the pallet weight to zero. After that, the glass plate is placed on the pallet and the weight signal of the loaded glass plate is set in advance by the controller. Judge that the plate is loaded, output the counter addition signal to the counter, reset the weight of the weighing machine to zero, and wait for loading of the next glass plate.

As described above, the weight of the glass sheet is compared with the set value each time the sheet is loaded, so that even if the slip sheet is inserted between the glass sheets, the weight of the slip sheet becomes almost negligible. Since the weight is not converted, it is possible to accurately calculate the number of loaded articles.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method and an apparatus for counting the number of loaded glass sheets according to the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a schematic side view of a method and an apparatus for counting the number of glass sheets loaded according to an embodiment of the present invention, and FIGS. 2, 3 and 4 are glass diagrams each illustrating an embodiment of the present invention. 1 shows a side view, a front view, and a plan view of a method and an apparatus for counting the number of loaded boards, in which a part of the method and the apparatus are notched.

As shown in FIGS. 1 to 4, there is a turntable 2 framed in a rectangular shape, which can be rotated 180 degrees on the floor. Two sets of weighing machines 11 having a load cell 12 for loading measurement and pallet replacement are provided on the turntable 2, and pallet receiving tables 6, 6,... The provided pallet support frames 5 and 5 are attached, and the legs of the pallet 7 are placed on the pallet support 6.

The load cells 12, 12 are the controller 1
3, the weight signal measured by the load cell 12 is transmitted to the controller 13, and the type, weight, upper / lower limit weight, etc. of the glass plate 1 previously set and input to the controller 13 and the glass loaded on the pallet 7. The weight of the plate 1 is compared, and if it is within the specified range, an addition signal is output to the counter, and a zero reset signal is output to the weigher.

Before the loading of the glass plate 1, the weights of the pallet 7 and the pallet supporting frame 5 are measured by the weighing machine 11. When a tare cancellation command is given to the controller 13, the weighing machine 11 causes the pallet 7 and the pallet supporting frame 5 to weigh. Reset the count value for the weight of to zero. Thereafter, when the glass plate 1 is loaded on the pallet 7 and the weight signal of the loaded glass plate 1 is continuously output to the controller 13 for a certain period of time, for example, 5 seconds, the weight is compared with the set value. If so, add the counter addition signal to Counter 1
4, the weight of the glass of the weighing machine 11 is reset to zero, and the weighing machine 11 waits for loading of the next glass plate 1.

Each time one glass sheet 1 is stacked, one sheet of interleaf paper 22 laminated at the upper position is taken out and inserted between the glass sheets 1 and 1 to prevent scratches due to contact between the glass sheets 1 and 1. Like that.

The slip sheet 22 is stacked on a slip sheet table 27 provided on a stand 21 erected from the floor surface.
The ends of a pair of interleafable paper delivery rolls 24 are pivotally mounted at the ends of a pair of rotatable arms 25 which are axially attached to both ends of the
, And the interleaf delivery roller 24 is rotated by the rotation of the interleaf delivery motor 23 connected by a belt (not shown), and is sent out from the uppermost surface of the interleaf 22 one by one to the loading operator side. This makes it easier for the operator to take out the slip sheet 22.

As described above, the weight of the glass sheet 1 is converted into the number of sheets by the controller 13 every time the glass sheet 1 is loaded. Is almost negligible and is not converted by the total weight of the loaded glass plates 1, 1,..., So that the number of loaded sheets can be calculated accurately.

When the loading of the glass plates 1 reaches the set number, a display indicating that loading is completed is made, and the alarm lamp 15 is turned on. The operator releases the fixed lock 3 that has locked the turntable 2, rotates the turntable 2 by 180 degrees with the handle 20, and stops the rotation of the turntable 2 with the turntable stopper 4 at the position where the turn of the turntable 2 is stopped. The turntable 2 is fixed by any one of 3 ′.

The rotating operation of the turntable 2 by the handle 20 is performed manually, but may be performed automatically by a motor. By rotating the turntable 2 by 180 degrees, the loading pallet 7 for loading the glass plate 1 and the empty pallet 7 'without loading the glass plate 1 are switched, and the loading operation can be continued immediately.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various applications can be considered. When loading small glass such as a side glass (rear quarter) of an automobile, there is a unit stack in which a plurality of, for example, about 10 glass plates are loaded together in order to improve workability. In order to cope with such a case, the present invention prepares a unit input in addition to the above-described one-sheet input, and in the case of a unit input, for example, if the weight of ten sheets is set and input, the above-described setting input is performed. Similarly, accurate counting of the number of loaded sheets can be performed. In this case, the loading unit is not limited to ten, and may be one or around ten.

As described above, the weight of the glass sheet 1 is compared with the set value each time the sheet is loaded, so that the slip sheet 22 is
Even if it is inserted in the middle, the weight of the interleaf 22 becomes almost negligible and is not converted by the total weight of the loaded glass plates 1, 1,..., So that the number of loaded sheets can be calculated accurately.

Here, the glass plate 1 is unreinforced, semi-reinforced,
A tempered glass plate, or a laminated glass plate composed of a combination thereof and bonded with an interlayer film, a multi-layered glass plate, or a glass plate stuck with a shatterproof film or the like, or a flat glass plate to a bent glass plate may be used. The shape thereof can be applied to a variety of shapes ranging from those for general buildings to windshields for vehicles, rear glasses, side glasses, sunroof glasses and the like.

In addition to glass plates, ceramic plates,
The present invention can also be applied to loading of a metal plate, a synthetic resin plate, pottery, and the like, and further, loading of a block-shaped body.

[0025]

According to the present invention, when a glass plate is manually loaded on a container such as a pallet, the number of loaded sheets can be automatically counted and counted, and the number of loaded sheets can be accurately grasped and managed, and highly accurate measurement can be performed. Not only can the result be obtained, but also the work efficiency is good, and the effect is remarkable, such as quick measurement.
