Abstract

PURPOSE:To facilitate handling by lowering a movable rail in the slit of the floor surface so as to bring the base paper roll receiving plate to the same level as the wall surface, then lifting the movable rail after placing the base paper roll on the receiving plate, and moving the vehicle body within the slit. CONSTITUTION:A vehicle body 6 is moved along a guide part 5 formed in the slit of the floor surface 3 by sprockets 12, 13 and a chain 14 driven by a motor M. In an unillustrated base paper roll loading position, a movable rail 17 formed by cutting (15) a rail 1 is lowered by the flexible tube 19 of an elevating drive unit 18 so as to bring a receiving plate 10 on the upper face of the vehicle body 6 to the same level as the floor surface 3. After the transfer of the base paper roll onto the receiving plate 10, the flexible tube 19 is expanded to lift the receiving plate 10 and to move the body 6 onto the sprocket 12 side. The base paper roll of heavy weight can be thereby loaded easily.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a base paper roll shooter for a mill roll stand in a corrugated board manufacturing machine.

[Conventional technology]

As a base paper roll shooter, a rail is buried in the floor along the mill roll stand, the top surface of this rail is aligned with the floor surface, and a car body is installed on a guide part in the rail so that it can run freely.
It is known that the upper end thereof protrudes onto a rail, and a receiving tray for the base paper roll is fixed to this. In this type of base paper roll shooter, since the tray protrudes from the floor surface, it is extremely difficult to place a roll of base paper weighing 30 to 1800 kg placed on the floor onto the tray.

[Problem to be solved by the invention]

The present invention solves the above problem by making the tray parallel to the floor surface when placing the base paper roll on the tray, and also by raising the tray after the base paper roll is placed. The purpose is to enable the movement of the tray and to prevent the rail from interfering with the movement of a vehicle such as a forklift, as in the past.

[Means to solve the problem]

The base paper roll shooter according to the present invention is embedded in the floor, and has a top surface aligned with the floor surface so that the tip of the rail faces one side of the mill roll stand, and a guide portion is formed in the rail,
In a base paper roll shooter in which a car body is provided on the guide part so as to be freely movable, the upper end of the vehicle body projects above the rail, and a receiving tray for the base paper roll is fixed to this, a cutting part is provided at the rear end of the rail, and the cutting part A movable rail is fitted to the movable rail so that it can be raised and lowered, and this movable rail is equipped with a lifting drive device that has a stroke such that the top surface of the movable rail matches the top surface of the rail when rising, and the top surface of the saucer matches the top surface of the rail when descending. It is characterized by being connected.

[For use]

As shown in FIG. 4, when the movable rail 17 whose upper surface is aligned with the floor surface 3 is lowered by the lifting drive device 18, the upper surface of the saucer 10 is aligned with the floor surface 3 as shown in FIG. , the base paper roll 11 placed on the floor can be easily placed on the tray 10. After mounting, when the movable rail 17 is raised, the movable rail 1
7 and the rail 1, and the tray 10 protrudes from the floor surface 3, the vehicle body 6 can be moved, and the base paper roll 11 can be moved. Further, in this case, since the upper surface of the movable rail 17 coincides with the floor surface 3, a vehicle such as a forklift can run without any trouble.

【Example】

An embodiment of the present invention will be described based on the drawings. Reference numeral 1 denotes a pair of left and right rails that are buried in the floor and have their tips facing a mill roll stand 2. This rail 1 has its top surface facing the floor 3.
A slit 4 is formed over the entire length, and is communicated with a guide portion 5 formed inside over the entire length. 6 is a vehicle body provided in the guide portion 5 so as to be freely movable;
Both front and rear axles 8 are provided on the frame 7, and wheels 9 provided at both ends thereof are supported on the bottom surface of the guide portion 5 so as to be freely movable. Further, the upper end of the frame 7 protrudes from the slit 4 onto the rail 1, and a saucer 10 is fixed thereto. This saucer 1
0 has a dish-shaped upper surface in cross section so as to be able to stably support a base paper roll 11 having a diameter of 20 to 150 m, a length of 80 to 250 a+1, and a weight of 30 to 1,800 kg. Further, the vehicle body 6 is connected to both ends of a chain 14 which passes through the rail 1 and is endlessly hooked onto subblocks 2.13 provided at the front and rear. M is its driving motor. Reference numeral 15 denotes a cut portion provided at the rear end of the rail l, and a recessed portion 16 is formed on the lower side of the cut portion 15. Further, a movable rail 17 having approximately the same length is fitted into the cutting portion 15 so as to be able to move up and down. This movable rail 17 has a cross-sectional shape of rail 1.
It has the same shape as , and has a length that allows the vehicle body 6 to be placed thereon with plenty of room. Reference numeral 18 denotes an elevating drive device installed in the recessed portion 16 and having a movable rail 17 connected to its upper end. This elevating drive device 18 has a flexible tube 19, and by pressurizing air from a compressor into this to raise the movable rail 13, the upper surface of the movable rail 13 is made to coincide with the upper surface of the rail l, and in this state, the inside of the flexible tube 19 is By lowering the air pressure and lowering the movable rail 17, the upper surface of the vehicle body 6 positioned on the movable rail 17 is brought into alignment with the floor surface 3. Note that this lifting drive device 18 is not limited to the flexible tube 19. Since one embodiment of the present invention has the above configuration, the second embodiment
After positioning the vehicle body 6 within the movable rail 17 as shown in FIG.
0 coincides with the floor surface 3, the base paper roll 11 carried on the floor can be easily placed on the tray 10. Therefore, when the movable rail 17 is raised by the lifting drive device 18, the movable rail 17 and the rail 1 are aligned as shown in FIG. 6 runs inside the guide part 5, and can easily feed the heavy base paper roll 11 on the receiving tray 10 to one side of the mill roll stand 2. In the above embodiment, the case where the vehicle body 6 is driven by power is shown, but the vehicle body 6 may be driven manually.

【effect】

According to the present invention, there are the following effects. - When lowering the movable rail, the upper surface of the tray is flush with the floor, so the base paper roll on the floor can be easily placed on the tray manually. ■ When the movable rail is raised, its upper surface is flush with the floor, so the chute does not get in the way when a vehicle such as a forklift is driven.
