Abstract

PURPOSE:To realize the automation of the measurement and selection of roller characteristics, by integrally controlling a roller supply part, a characteristic measuring part (outer diameter and hardness), a discharge part selected by characteristics to be received and a feed robot. CONSTITUTION:A roller 11 is taken out from a roller supply part 14 to be fed to an outer diameter measuring part 15 in a process (a) to automatically measure the outer diameter dimension of the roller 11. When the measured result is transmitted to a control part 18, the storing and discrimination of the measured value in the control part is performed [process (b)]. A feed robot 17 transfers the roller 11 from the outer diameter measuring part 15 to a hardness measuring part 16 by the measurement completion signal of the outer diameter measuring part 15 [process (c)]. Similarly, the transfer of the roller 11 is detected and hardness is automatically measured while the measured value is transmitted to the control part 18 where the storing and discrimination thereof are performed [process (d)]. In the control part 18, the outer diameter measured value and the hardness measured value are classified by a rank and a discharge order is issued to the feed robot 17 on the basis of the results [process (e)]. The feed robot 17 discharges the roller to a discharge part 19 divided at every predetermined rank on the basis of said order [process (f)].

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to an automatic sorting device for paper feed rollers.

[Background of the invention]

Conventionally, as a measure to prevent skis related to the paper feed mechanism, there has been a mechanism that detects the paper feeding state using an optical sensor or the like and corrects the skis by controlling the drive of a stepping motor for conveyance based on this detection signal. Kaisho 59-9
No. 1076, Japanese Patent Application Laid-Open No. 59-140085, and Japanese Patent Application Laid-Open No. 59-145664 are known, but they were aware of the prevention of the occurrence of the sagging itself).

On the other hand, as a preventive measure against the occurrence of skew itself, there is a mechanism in JP-A-59-164170, in which a paper presser roller is arranged in a square shape with respect to a paper feed roller. In addition, it was necessary to make the inclination angle accuracy of the left and right paper press rollers highly accurate. For this purpose, the outer periphery of each of the paper feed roller and paper press roller is made of an elastic material, and the roller and shaft are constructed so that they can be assembled as separate parts.The outer diameter of the roller and the hardness of the elastic material are measured in advance. devised a mechanism to prevent skiing by incorporating rollers with the same characteristics into a single shaft, but measuring the outer diameter of the rollers, measuring the hardness of the elastic body, and sorting them were done manually. It was done by work.

[Purpose of the invention]

The purpose of the present invention is to eliminate the above-mentioned conventional problems, and to provide a paper sheet which should be used to automate the measurement and sorting of roller characteristics (outer diameter dimension and hardness) as a ski prevention measure. The purpose of the present invention is to provide an automatic sorting device for feed and rim rollers.

[Summary of the invention]

The feature of this invention is that it automates the process of measuring and sorting the characteristics of paper feed rollers, which was conventionally done manually (roller supply section and characteristic measurement section (outer diameter and hardness),
We have a discharge section that sorts and stores items based on their characteristics, and the rollers are automatically transported by a transport robot and a control device that controls the entire system, and the characteristics are automatically measured and sorted based on the results.
・It discharges water.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings.

Fig. 1 is a sketch showing an example of a paper feeding mechanism, Fig. 2 is a plan view illustrating changes in feed amount due to differences in roller outer diameter, and Fig. 3 is a plan view illustrating changes in feed amount due to differences in roller hardness. FIG. In general, a paper feed mechanism consists of a paper feed roller assembly 1 and a paper presser roller assembly 2. is given a rotational force from a drive source 5 by a power transmission unit 4.On the other hand, paper sizes may be different, such as paper A6 and paper B7.
In the roller assembly, as shown in FIG. 2, if the outer diameters of the paper feed roller 8 and the paper presser roller 9 are different within one roller assembly, the outer circumference of the rollers will be different.
Even when the same shaft rotates once, the paper feed amount A differs by the amount of the roller outer circumference, which results in skiing. Further, as shown in FIG. 3, if the paper feed roller 8 and the paper press roller 9 have different hardnesses, the contact surfaces with the paper will be different, which will also cause skinny. In order to prevent these skis from occurring, as shown in the exploded perspective view of the roller assembly in FIG.
As shown in FIG. 5, the outer diameter of the roller 11 is set as follows:
The hardness is measured using a non-contact measuring device such as a laser micrometer, and as shown in FIG. 6, the hardness measuring device 13 is applied to the outer periphery of the roller 11 to apply a deformation H to the elastic body under a constant pressure to measure the deformation. The hardness of the elastic body can be measured by the amount of
The hardness of the elastic body 1 is measured by the amount of pressure on the elastic body when a constant deformation amount H is applied), and the ranks in Fig. 7 are divided into ranks according to external dimensions and hardness, as shown in the table, and parts of the same rank are compared. By using a single roller assembly, parallel paper feeding becomes possible.

The outer diameter dimension is automatically measured; the result is electronically transmitted to the control unit 18, and the measured value is stored and discriminated in the control unit 18 (port C). Outer diameter 1 - In response to the measurement completion signal from the measuring section 15, the transport robot 17 transfers the roller 11 from the outer diameter measuring section 15 to the hardness measuring section 16. Similarly, the transfer of the roller 11 is detected, the hardness is automatically measured, and the measured value is electronically transmitted to the control unit 18 for storage and discrimination. 0 sea urchin). Next, the control unit 18 ranks the outer diameter measurement value and the hardness measurement value, and issues a discharge command to the transfer robot 17 based on the results (e). Transfer robot 1
