に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a length measuring device, and more particularly, the present invention relates to a length measuring device, and more particularly, it is capable of automatically measuring the length of various non-rigid objects such as cigarette filters, cigarettes, and cigars. The present invention relates to a length measuring device useful for measuring length.
[従来の技術と発明が解決しようとする課題]従来、比
較的則性が大きな長尺状則性体の長さは、ノギス等の測
定器を用いて測定されている。[Prior Art and Problems to be Solved by the Invention] Conventionally, the length of a long regular body with relatively large regularity has been measured using a measuring instrument such as a caliper.
しかしながら、ノギスを用いて上記たばこ用フィルタ等

時の押圧力の変動により大きく変形し、測定結果が大き
くばらつく。従って、上記の測定器によると、迅速かつ
正確にたばこ用フィルタ等の長さを測定するのが困誼で
ある。However, when a non-rigid body such as the above-mentioned cigarette filter is held between the calipers and the length of the non-rigid body is measured, the length of the non-rigid body is greatly deformed due to fluctuations in the pressing force during measurement, and the measurement results vary widely. Therefore, it is difficult to quickly and accurately measure the length of a cigarette filter, etc. using the above measuring device.
一方、たばこ用フィルタや紙巻きたばこ等の生産量は膨
大である。またこれらの製造時や、製品の出荷及び受入
に際しては、たばこ用フィルタ等の長さに関して厳しい
品質管理が要求されている。On the other hand, the production volume of tobacco filters, cigarettes, etc. is enormous. In addition, strict quality control is required regarding the length of cigarette filters and the like during their manufacture and when shipping and receiving the products.
すなわち、たばこ用フィルタ等の巻上げ、装填は連続的

Publication No. 1). FIG. 4 is a schematic side view showing a conventional length measuring device. This device includes a sample stage (24) in which a groove (23) is formed to fix one end of a long non-rigid body (21) with a stopper (22), and the other end of the non-rigid body (21). A fulcrum (25) provided above; an arm (26) swingably suspended from the fulcrum (25);
The first weight (27) is attached to the tip of the non-rigid body (21) and is capable of contacting the other end of the non-rigid body (21). In order to move the rigid body (21) to the other end, a second weight (28) is attached to the arm (26), and a first weight (28) is attached to the arm (26).
A sensor (29) that detects the position of the sample stage (27)
24).

することができる。According to the above length measuring device, a non-rigid body (2
1) When measuring the length, the first weight (27)
is in contact with the other end of the non-rigid body (21), and the sensor (29) detects the displacement j of the first depression (27), thereby determining the length L of the non-rigid body (21). Ten J can be measured.

の長さを正確に測定することが困龍である。However, the above measuring device is fixed and the sample stage (24
), so if the reference length of the non-rigid body (21) is different, it is difficult to quickly and accurately measure the length according to the reference length of the non-rigid body (21). More specifically, for example, in the case of a cigarette filter, a standard length of 102 mm or 120 mm is adopted depending on the type. Therefore, in order to measure the length of cigarette filters with different reference lengths, it is necessary to prepare multiple measuring devices depending on the type of cigarette filter, and one device can measure the length of cigarette filters with different reference lengths. It is difficult to measure the length accurately.

Regardless of the standard length of the filter plug (1), the length can be measured at an appropriate position. In addition, when measuring the length according to the type of cigarette, the degree of advance according to the standard length of the filter plug (1) is stored in the ROM of the control unit, and the stored data and the rotation speed of the motor (8) are used. Based on this, the controller may control the forward and backward movement of the moving table (7).

A non-contact minute displacement sensor (18) for detecting the distance between the support column (11a) and the target member (16) is attached at a location facing the support column (16). Further, on the upper surface of the wall portion (6b) on the side where the motor (8) is disposed, there is provided the movable table (7).
An origin switch (19) is provided in order to stop the movement of the moving base (7) at the origin position when the movable table (7) is retracted.

フィルタプラグ(1)の長さを測定することができる。Therefore, as shown in FIG. 2, when the moving platform (7) is advanced beyond the standard length of the filter plug (1), the abutment attached to the swingably suspended rod (13) Since the member (14) retreats rearward, the filter plug (1
) length J=S+LO can be measured. At this time, the contact member (14) etc. move forward and backward together with the movable base (7), and the movable base (7) can be returned to the origin position by the origin switch (19), so that the filter plug (1) Even if the reference lengths are different, the length of the filter plug (1) can be measured quickly and accurately.

) As shown in (B), if I is the moving distance of the movable platform (7) that can quickly respond to filter plugs (1) with different standard lengths, then C=L+I (C is a fixed value). set to the position. More specifically, when adapting to a filter plug (1) with a length of 60 to 150 mm, the standard length L=
For 120IIlm filter plug, C>150mm
It is set so that the

It becomes L-A. Therefore, even if the reference length of the filter plug (1) is different, LO indicates a constant distance from the reference length.

Further, an appropriate number of regulating members may be provided. Furthermore, the sensor
It suffices if it is attached to an opposing location of either the target member or the above-mentioned support in an area where the distance between the target member and the support can be detected. Further, a side plate facing the target member may be provided in series with the support column, and a sensor may be attached to the side plate within a range that does not impede the swinging of the abutting member.

に長さを測定できる。[Effects of the Invention] As described above, according to the length measuring device of the present invention, the abutting member is provided on the rod swingably suspended between the upper parts of the supports, and the target facing the abutting member is provided with the abutting member. It has a sensor that detects the distance between the member and the support column, and the measuring device can move forward and backward in the axial direction of the non-rigid body, so even if the reference length of the non-rigid body is different, one device can be used. You can measure length quickly and accurately.
