BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a semi-conductive rubber roller used for a printer, a facsimile, a copying machine, etc., which is continuously rotated and its electric resistance is automatically measured. The present invention relates to a sorting device in an automatic measuring device for a resistance value of a conductive rubber roller separately sorted.

2. Description of the Related Art FIG. 4 shows a conventional conductive rubber roller (8).
FIG. 4 is a diagram showing a resistance measuring jig of the present invention, which is an aluminum plate for mounting and measuring a rubber roller (8), a digital resistance measuring instrument (6), and a rubber roller ( 8) A load of a predetermined weight placed on the core material, and an electrode is provided upright on one end of the aluminum plate and connected to the digital resistance measuring instrument (6). When measuring the resistance of the rubber roller (8) using this resistance measuring jig, the measurer first places the rubber roller (8) on an aluminum plate and projects from both ends. A predetermined load, for example, 300 g is applied to the core material. And rubber roller
Another electrode is connected to the core material of (8). Thereafter, the measurement was performed by applying a voltage, and the measurer recorded on a recording paper. For example, a value 10 seconds after applying a voltage of 1000 volts was measured and the value was recorded. At this time, the measuring point was set at 90 ° or 12 ° in the circumferential contact portion of the rubber roller (8).
The measurement method was such that the measurement was performed at three to four positions by rotating the lens every 0 degrees. Thereafter, the measurer determines whether or not all the measured values fall within the standard range, and sorts and sorts the non-defective and defective rubber rollers (8). In this case, the measurer judges whether all the measured values are within the standard range, and when a defective product is generated, the user moves to another place or a container or the like and distinguishes it so that it does not mix with a good product.

[0003]

However, in the case of sorting the non-defective and non-defective rubber rollers (8) by sorting, the measurer moves the defective product to another place or container while judging. Sorting must be performed so as not to mix with non-defective products, and since the work from measurement to sorting is performed by one person, it is troublesome and measurement work efficiency is poor. In addition, the rubber roller
In the measurement of (8), it is difficult to perform automatic measurement so as to obtain a stable measurement value.
The automatic measuring device and the sorting device of (8) did not exist before.

The present invention has been disclosed by the present inventors in Japanese Patent Application No. 2000-171.
According to the automatic measurement of the conductive rubber roller automatically measured by the resistance value measuring device proposed in No. 394, the non-defective product and the defective product or the defective product can be further conveyed automatically by further discriminating between the above and below the standard. It is an object of the present invention to provide a sorting device in an automatic measuring device for measuring the resistance value of a conductive rubber roller which can be sorted by means of a roller.

The measuring member (4) is a The inventor may use the one used in the embodiment in Japanese Patent Application No. 2000-171394. (6) is a digital resistance measuring instrument connected to the shaft end of the measurement roller (21) and the core material end of the rubber roller (8).

FIG. 3 is a diagram showing the operation of the present invention, and the description will be made based on this. First, the rubber roller (8) automatically measured while rotating continuously receives the receiving roller (4).
It descends while being supported by 2) [see FIG. 3 (a)]. Then, the core material of the rubber roller (8) hits the inclined surface on the upper left of the receiving claw (11) of the receiving member (1), and further receives the receiving roller (42).
Is lowered, the core material of the rubber roller (8) moves from the receiving roller (42) to the receiving claw (11) while moving to the center of the V-shape (see FIG. 3 (b)). Receiving nail (1
After the transfer to 1), the receiving member (1) descends to the lowest position. At this time, a transporter (3) for non-defective products is arranged in the upper right, and a lower right for defective products of a standard or higher, and a lower left for a defective product of lower than a standard.
Are arranged [see FIG. 3 (c)]. A detailed description will be given of the transport distribution step in the case where the rubber roller (8) is determined to be a non-defective product while the receiving claw (11) of the receiving member (1) is being lowered. First, when the receiving claw (11) of the receiving member (1) starts to descend, a command is issued from the control device (5) to the transfer device (3) for transferring a non-defective product, and the upper right cylinder (22) Is actuated, and the delivery piece (21) is pushed out in the horizontal direction, and waits on the inner side of the descending line of the receiving claw (11). When the receiving claw (11) comes down by the lifting cylinder (12), the rubber roller
The core material of (8) is transferred from the receiving claw (11) to the delivery piece (21), and moves from the upper left inclined surface of the delivery piece (21) to the center of the V-shape (see FIG. 3D).

Then, the cylinder (22) is pulled back, the delivery piece (21) returns to its original position, and is moved to the fixed piece (31) of the non-defective transfer machine (3) [FIG. 3 (e)]. reference]. Next, the vertical movement cylinder (33) is operated and the movable piece (32) is raised in a horizontal state, and the top of the movable piece (32) approaches the left side of the core material of the rubber roller (8). When the apex rises further, the core material of the rubber roller (8) changes over to the movable piece (32) and moves from the right inclined surface of the apex to the valley as shown by the arrow in the figure [FIG. )reference]. When the movable piece (32) immediately descends, the core material of the rubber roller (8) changes from the valley of the movable piece (32) to the right side of the top of the fixed piece (31), as shown by the arrow in the figure. The valley of the delivery piece (21) placed first is moved to the valley of the fixed piece (31) [see FIG. 3 (g)]. Next, the movable piece (3
2) When the core material of the rubber roller (8) moves from the fixed piece (31) to the movable piece (32) and moves to the right valley when the movable piece (32) starts to descend, , Rubber roller
The core material of (8) is moved to the valley on the right side of the fixed piece (31). By moving the movable piece (32) up and down in this manner, the rubber roller (8) is sequentially conveyed to the right side and conveyed to a predetermined position.

The control device (5) is a rubber roller (8).
Is judged to be defective or higher than the standard, the delivery piece (21) of the delivery member (2) at the lower right is pushed to the left, and the delivery piece (21)
The rubber roller (8) is transferred from the receiving claw (11) to the lower position, and the rubber roller (8) is transferred to the lower right and right sides. When the control device (5) determines that the rubber roller (8) is defective below the standard, the delivery piece (21) of the delivery member (2) at the lower left is pushed out to the right side and received by the delivery piece (21). After receiving the rubber roller (8) from the claw (11), the rubber roller (8) is moved to the lower left and to the left. In this way, the paper is conveyed and sorted into three types: non-defective products, higher quality standards and lower quality standards. or,
In the case where the determination is divided into two items, a good product and a defective product, the defective product may be conveyed to the lower right and to the right.
