帯状材のテンションを一定に維持することができる。"Prior Art" A dancer roll device has a function of defining a part of a conveyance path for conveying a strip material, and storing and holding a portion of the strip material. Therefore, if a dancer roll device is inserted in the conveyance path, for example, even if a problem occurs in the unwinding of the strip material upstream of the dancer roll device, the unwinding of the strip material throughout the conveyance path will be possible. Not only is there an advantage that the strip material stored in the dancer roll device can be sent out toward the downstream side of the conveyance path without stopping, but also the tension of the delivered strip material can be maintained constant.

かることになる。``Problems to be Solved by the Invention'' By the way, the conventional dancer roll device uses at least two fixed-side guide rollers and a section below between these fixed-side guide rollers to compensate for the difference between the input amount and output amount of the strip material. Since it is composed of a movable guide roller that moves up and down according to the
First, the strip material is passed through a dancer roll device,
Moreover, in order to pass the strip material through the dancer roll device again after a break occurs in the strip material, it is necessary to guide the strip material by passing it around the fixed-side and movable-side guide rollers in sequence. The number of guide rollers on the fixed side and the movable side also increases as the amount of band material required for the dancer roll device increases. The number of times the process is repeated also increases, and it becomes time-consuming to perform the process.
この発明は、このような事情に基づいてなされたもので
、その目的とするところは、案内ローラ、特に、可動側
案内ローラの数に拘りなく、帯状材を簡単にして通すこ
とができるダンサロール装置を提供することにある。The present invention was made based on the above circumstances, and its purpose is to provide a dancer roll that can easily pass a strip of material regardless of the number of guide rollers, especially the movable guide rollers. The goal is to provide equipment.
「課題を解決するための手段」
この発明によれば、ダンサロール装置は、固定側案内ロ

づいて制御されることになる。Then, the dancer roll device moves in accordance with the difference between the input amount and the output amount of the strip material, that is, the packaging material A, guided through the plurality of guide rollers 3 that define a part of the conveyance path. It is equipped with four movable guide rollers 4, and these movable guide rollers 4 allow a predetermined length of packaging material A to be stored. In addition, the movable guide roller 4
Since the basic operating structure is well known, its explanation will be omitted here. However, at the bottom of the dancer roll device, there is an upper limit sensor 5 for detecting the upper limit position and lower limit position of the movable guide roller 4. and a lower limit sensor 6 are fixedly arranged, respectively, and the movable guide roller 4 is positioned between the upper and lower limit sensors 5 and 6 based on the detection signals from these upper and lower limit sensors 5 and 6. There is. In other words, the feeding speed of the feed roller (not shown) located upstream of the dancer roll device in the conveyance path is controlled based on detection signals from the upper and lower limit sensors 5.6.

の挿通路Ｂが形成されることになる。On the other hand, the elevating carrier 7 is guided by three guide rods 8 and can be raised and lowered freely, and the elevating carrier 7 is raised and lowered as necessary by a rodless cylinder 9 that constitutes a moving mechanism. It has become. In this case, the lifting range of the lifting carrier 7 by the rodless cylinder 9 is above the fixed guide roller 2, and therefore the movable guide roller 4 is moved upwardly, as is clear from FIG. It is possible to rise beyond the fixed side guide roller 2. When the movable guide roller 4 is positioned above the fixed guide roller 2 in this way, the packaging material A is placed between the fixed guide roller 2 and the movable guide roller 4.
An insertion path B is formed.
