BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cut material weight measuring apparatus for automatically measuring the weight of a cut material cut by a cutting machine.

[0002]

2. Description of the Related Art Conventionally, as for a cut material cut with a sawing machine, for example, before the cut material is applied to a forging machine, the weight of the cut material must be measured in order to prevent mold breakage and eliminate product defects. Is being done. In reality, this weight measurement operation relies on the hand of an operator.

[0003]

By the way, the weight measurement of the cut material cut by the conventional sawing machine described above has a problem that labor saving and improvement in productivity cannot be expected because it depends on humans. . Furthermore, in recent years the system band saw was completed,
Although it is possible to automatically carry out the product, there is a problem in that the weight measurement of the cut material becomes a bottleneck and the entire line cannot be automated.

[0004] The purpose of this invention is to improve the above problems by automatically weighing the product during cutting-out of the product to save labor and improve productivity. It is an object of the present invention to provide a cut material weight measuring apparatus that automates the entire line, for example, when the measured value is measured, is carried out to a defective product address.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cutting material weight measuring device for measuring the weight of a cutting material cut by a cutting machine, which is disposed in front of the cutting machine. A carriage that can reciprocate in the front-rear direction is provided on the unloading device, a clamp jaw that clamps the cutting material is provided on the carriage, and a movable vice body that is movable up and down is provided. A measuring device for measuring the weight of the cut material was provided in the carriage.

[0006]

By adopting the cut material weight measuring device of the present invention, a carry-out device for carrying out the cut material after cutting is provided, for example, on the front side of a sawing machine as a cut material. In this unloading device, a carriage is provided movably in the front-rear direction, a clamp jaw for clamping a cut material cut by the carriage, and a movable vise body which holds the clamp jaw and is movable vertically. . Therefore, the cut material is clamped by the clamp jaws, the material is lifted by the movable vise body, and moved by the carriage to carry out the material.

During the unloading, that is, when the cut material clamped by the clamp jaws is lifted by the movable vice body, the weight of the cut material is measured by the measuring means provided in the carriage. Thus, for example, when an unspecified product weight is measured, the line is automated by means such as carrying out a cutting material to a defective product address, thereby saving labor.

The product W is lifted by lifting the movable vise body 31 with the lift cylinder 53, and the carriage 29 is moved to a predetermined position by the drive of the drive motor 41, and the long material product delivery table 35 or the short material product delivery is performed. Table 37
Alternatively, the clamp jaw 33 is moved to a suitable one to release the clamp and carry out the product W.

Next, the cut material weight measuring device will be described in detail.

Referring to FIG. 1, a cutting material weight measuring device 6
9 is a clamp jaw 33 provided on the carriage 29.
A lift cylinder 53 is provided for moving the movable vise body 31 provided with a vertical direction, and a hydraulic circuit 71 for operating the lift cylinder 53 is provided with a measuring means 73. More specifically, the hydraulic circuit 71 is connected to the tank 7
From 5, the hydraulic oil is sent to the port P of the electromagnetic switching valve 79 by the hydraulic pump 77, and the ports A and B are selected by switching the electromagnetic switching valve 79.

When switching to the port A of the electromagnetic switching valve 79, the pressure oil is supplied from the pump 77 to the lower oil chamber 83 of the lift cylinder 53 through the pilot check valve 81. Oil chamber 83 and the pilot check valve 81
Between the measuring means 73 and the pressure detecting device 85, for example.
Is provided. At this time, the oil in the upper oil chamber 87 of the lift cylinder 53 is returned from the port B of the electromagnetic switching valve 79 to the tank 75 via the port R.

Therefore, the clamp jaw 33 holding the product W rises while being guided by the guide shaft 49 provided on the movable vise body 31. At this time, the product weight is measured by the pressure detection device 85. That is, as shown in FIG. 2, the pressure in the lower oil chamber 83 (on the head side) of the lift cylinder 53 when the product W is lifted (at the time of load) when the product W is not present (at the time of no load). The difference between the pressure of the lower oil chamber 83 and the lower oil chamber 83 of the cylinder 53 is determined.
Is multiplied to obtain the measured product weight Wg. Further, comparing the measured product weight Wg with the calculated product weight Wc, it is possible to carry out sorting and carrying out to a product carrying-out yard in the case of YES and to a defective yard in the case of NO.

[0030] At present, the work that requires the most labor in cutting steel materials is the work in product processing.

(1) Cutting off the product (2) Checking the product, that is, length, diameter, material, weight, etc. (3) Marking work (4) Preparation for shipment (palletizing) Of the above, products related to weight according to the present invention The check work is simplified, the weight is automatically measured while the product is being carried out after cutting, with a simple configuration, so significant labor savings and productivity improvements are achieved compared to the conventional operation performed by workers. Can be achieved. Further, when a product weight outside the specified range is measured, the entire line can be automated, for example, it is carried out to a defective product address.

The embodiment shown in FIGS. 3 and 4 shows the second embodiment. The difference from the first embodiment is that
Is provided on the lift cylinder 53, and the same members as those in the first embodiment are denoted by the same reference numerals and description thereof will be omitted.

That is, the measuring means 73 is provided between the piston rod 55 of the lift cylinder 53 and the connecting member 51. As shown in detail in FIG. 4, for example, a load cell 91 serving as measuring means 73 is attached to the piston rod 55 via a washer 89, and the upper surface of the load cell 91 is brought into contact with the lower surface of the connecting member 51 and The piston rod 55 is connected to the connecting member 51. Therefore, the load detected by the load cell 91 when the product W is gripped by the clamp jaw 33 and the movable vise body 31 is lifted by the lift cylinder 53 is different from the load of the load cell 91 when the product W is not gripped. By pulling, the measured product weight of the product W can be known. Thus, the effect is that coins similar to those of the first embodiment can be exhibited.

The present invention is not limited to the above-described embodiments, but can be implemented in other modes by making appropriate changes. For example, in this embodiment, the pressure detector 83 and the load cell 9
Although described using FIG. 1, a piezoelectric element or a strain gauge is attached to a part of the ascending configuration of the unloading device 23 including the clamp jaw 33, and the weight is detected based on stress, strain, and the like applied when the product W is lifted. Means are also possible.

[0035]

As will be understood from the above description of the embodiment, according to the present invention, the cutting material cut by the cutting machine is gripped by the clamp jaws, and the measuring means is moved in the process of ascending the movable vice body. Measure the weight of the cut material with. Therefore, the weight can be automatically measured while the product is being carried out after cutting with a simple configuration, and labor saving and improvement in productivity can be achieved. Further, when a product weight outside the specified range is measured, it is possible to automate the entire line, for example, to carry out the product to a defective product address.
