Abstract

PURPOSE:To safely make an inspection for the adjacent apparatus and carry in a tube by disposing a pair of closing plates capable of freely opening and closing, which are connected by a hinge for the opening portion of a groove portion and the upper opening portion of a cover plate in the above device for a process of manufacturing a heat exchanger panel. CONSTITUTION:During operation of the device, a closing plate 21 is located at a position 21' not to be an obstacle to moving, storing and discharging a tube, and as occasion demands, a groove 7 is closed. A closing plate 22 is opened at need for inspection of a cover plate 8 and the like. In this arrangement, the inspection of apparatus and carrying-in of a tube can be conducted safely.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a device for storing and supplying tube bodies, and more particularly to a device capable of closing the top surface of the device when the device is stopped.

Large industrial boilers, including boilers for power plants, have water tubes on the walls of the boiler, and heat transfer tubes are also placed in the flue to serve as energy savers, superheaters, reheaters, etc. For example, a energy saver is placed in the flue of a boiler, but in order to increase heat recovery efficiency, the tube is bent into multiple stages, and multiple bent tubes form a single heat transfer panel. , and by arranging a large number of these heat transfer panels via headers etc., an integrated energy saver is formed as a whole. The number of bent tubes (coils) varies depending on the type of boiler, but it can be as few as several hundred pieces or as many as 1,000 or so. For this reason, there is a demand for an apparatus that can efficiently manufacture a large number of panels, and the inventors have separately proposed such a manufacturing apparatus.

In order to efficiently manufacture such panels, it is necessary to store the various tubes that make up the panel by type, and to place the specified tubes in a tube processing device such as a bevel forming machine or pipe bender. A supply device is required.

<Technical background that led to the construction of the present invention> FIG. 3 shows a tube supply device separately proposed by the inventors in view of the above requirements.

The tube bodies 3 on the mounting table on which the tube bodies are placed are sequentially supplied to a beveling machine and adjusted to a predetermined length. On the other hand, on the side of the main body 6 of the tube storage device, in order to store the tube in the storage groove 7 corresponding to a predetermined type, the cover plate 8 of the storage groove in which the tube is to be stored is closed, and in conjunction with this, the storage groove 7 is closed. erected. At this time, all other cover plates are closed, and all stoppers corresponding to the closed cover plates are also pushed down. In this state, the tube body cut to a predetermined length moves while rolling on the slope of the device body 6, the cover plate is opened, and the tube body is dropped and stored in the storage groove in which the stopper 10 is erected. . Note that the lifter L supports the load of this fallen tube.

Next, when supplying the stored tube to the vendor side, open the cover plate 8 of the groove in which the specified tube is stored, but leave the stopper 10 tilted down). discharge. The discharged tube rolls down the slope of the device body and is supplied to the vibe bender.

For equipment located north of this region, should the adjacent pipe stocker, vibration bender, and other equipment be inspected when the equipment is stopped? In this case, the storage groove is open, so it is very dangerous to work with the tube supply device. The purpose of the guide bar plate 8 is to allow the tube to roll over the opening of the groove 7, so it is divided into a plurality of pieces in the longitudinal direction of the groove 7. It does not close the entire groove 7. Therefore, the cover plate storage section also has an open space at the top. Incidentally, if the cover plate is made completely closed, the plate weight q will increase, the power cost for operating the plate will increase, and it may cause malfunction, so a fully closed cover plate is not appropriate.

OBJECTS OF THE INVENTION The present invention was constructed in view of the above-mentioned problems, and is a tube supply device configured such that the top surface of the device becomes a flat surface when the device is stopped.

Summary of the Means> In short, the present invention is a tube supply device in which a closing plate that can be opened and closed with respect to the opening of the groove is attached so as not to impede the storage and discharge of the tube.

<Example> Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numerals 21 and 22 are a pair of closing plates formed by a hinge 23, and the hinge is located between the tube storage tIj 7 and the cover plate storage space 24 adjacent to this fjlj 7. It is arranged so that it is located in the partition part of.

Normally, the hinge 23 is constructed by cutting out the closing plates 21 and 22 and storing them in this part, and fixing them by welding so that the closing plates 21 and 22 and the hinge are located on the same plane. When stacked on another closing plate 22 like 21, the structure is such that the two come into close contact with each other and do not impede the transfer of the tube body. Reference numeral 25 is a reinforcing member placed at the bottom of the closing plate to increase the strength of the closing plate.It is welded only on the closing plate 22 side to ensure opening and closing of both closing plates, and when the closing plate 21 is opened, the pipe body h' to prevent the reinforcing member from protruding onto the transfer surface. Like this 17. The pair of closing plates formed by lj is t! I') 7 and a space 24 adjacent to this groove, and are configured to close the entire top surface of the device.

Of the closing plates configured as described above, the closing plate 21 is placed at the position 21 during the operation of the apparatus so as not to hinder the transfer, storage and discharge of the pipe body, and closes the groove 7 as necessary during the operation of the apparatus. do. Note that it is of course possible to open the closing plate 22 as needed, such as when inspecting the cover plate 8.

<Effects> By implementing the present invention, the first surface of the apparatus can be configured as a flat surface when the apparatus is stopped, so that equipment adjacent to the apparatus can be inspected, corrugated pipe bodies can be carried in, etc. safely.
