Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a lifting device for lifting any cylindrical object, such as a cylindrical object such as a coil or a film roll.

[Prior art]

When lifting cylindrical objects such as conventional paper rolls or film rolls, if the cylindrical core is placed horizontally, you can pass a rod or lobe through the core and lift it with a crane or forklift. can be easily done. When the cylinder is placed vertically, the outer circumference is INI! Doing so will damage the paper or film roll, so it is necessary to lift it using the inside of the core.

However, because the inner diameter of the winding core is small, loading and unloading has conventionally been carried out using methods such as silently using hanging devices that could be put to practical use to satisfy this need, and rolling them manually. In particular, when a plurality of rolls are placed close to each other, it becomes impossible to fold the rolls or grasp the outer periphery of the rolls, making it impossible to load and unload the rolls.

[Purpose of the invention]

An object of the present invention is to provide a hanging tool suitable for taking out a part of cylindrical objects when they are vertically arranged close to each other, or when arranging them vertically close to each other and attaching them to a pallet. Our goal is to provide the following.

[Summary of the invention]

The key point of the present invention is that after a cylindrical rubber block is inserted into a winding core at the center of a cylindrical object, the outer periphery of the rubber is pressed into contact with the inner diameter surface of the winding core by compressing and deforming the rubber using a cylinder or the like. There is a method of lifting equipment that obtains the necessary friction during lifting.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In Fig. 1, (1) the tool 2 is installed at the tip of the balance loader 1 to raise the roll 3 when stacking the roll 3 on a pallet 4I or conversely unloading it. use

The hanging tool 2 is as shown in FIG. In other words, a piston/cylinder device connected to the balance loader 1 by a pin? 75
A rubber receiving plate 12 is fixed to the lower end of the piston rod 7 fixed to the piston 6 with a nozzle 9 that is connected to the piston rod 7. A cylindrical rubber block 8 is fitted into the piston rod 7, and this block 8 is placed on a rubber catch 12. In addition, a spacer 10 is fitted between the upper surface of the rubber flock 8 and the cylinder of the piston/silling device 5. A rubber flock 8 is provided between the receiving plates 12 with a spacer 10 interposed therebetween. Equipped with.

Connect a pressure generating device such as a compressor to hoses A and B.

As shown in FIG. 2, the roll 3, which is the load, is made of a hollow cylindrical winding core 11 with one core of paper 13, filtrate, etc. wound around the outer periphery of the core 11, as shown in FIG.

In the wooden embodiment, as shown in FIG.
When pushed or pulled horizontally or vertically by hand, the hanger 2 moves in the pushing or pulling direction. By this movement 1), 8 parts of the rubber block of the hanging tool 2 are placed into the winding core 11. Thereafter, the air pressure from the pressure sending device is sent through the port A to the bottom of the piston/cylinder device 5 and to the cylinder indoor heat chamber. In this way, the screw 6 rises while discharging the air in the upper cylinder chamber from the port B, and pulls up the piston rod 7 and the comb receiving plate 12. Since the cylindrical rubber block 8 is prevented from moving upward by the spacer 101, the rubber flock 8 is made of luxurious rubber on the inner peripheral surface of the 11% core 11 which has been shrunk and has a large outer diameter. The outer circumferential surface of the block 8 is pressed. In this state, balance loader-1
When the hanging tool 2 is raised upward, the roll 3 is connected by the rubber block 8I of the lifting tool 2, so it is easy to
You can lift it.

When lifting roll 3 and moving it to a predetermined position using balance rotor 1 to release the hold, use hose B.
The piston 6 descends due to the heat generated by sending pressurized air, and the outer shape of the cylindrical rubber 8 returns to its original shape and is released.

In the wooden embodiment, a pneumatic piston cylinder device 5
is adopted as the telescopic drive device, but a hydraulic piston syringe device or an electric cylinder may also be used as the telescopic drive device.

According to this embodiment, since the cylindrical rubber block 8 is compressed to generate the frictional force necessary for raising ω, the structure is simple, and the outer peripheral surface of the rubber flock 8 is wrapped. Since it is in contact with the core 11, stable lifting is possible, and since the rubber block 8 is only in contact with the winding core 11, the winding core 11 is not damaged.

〔Effect of the invention〕

As described above, according to the present invention, since the lifting tool is provided which can press the comb whose width has been expanded due to compression to the inner circumferential surface of the cylinder of the cylindrical object, it is possible to lift the cylindrical object in a vertical state, and to This provides the effect that it is possible to easily take out some of the cylindrical objects from a plurality of cylindrical objects that are placed so close together that they cannot be knocked over or grabbed by their outer peripheral surfaces.
