Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an apparatus for cutting and processing waste having a hollow structure such as a tire and a pipe.
[0002]
[Prior art]
Various pipes such as polyethylene pipes used as gas pipes, polyvinyl chloride pipes for water supply, and flexible pipes for cables are discarded during construction. It is the construction site that emits these materials as waste materials, and it can be seen that there are almost no processing facilities nearby. Therefore, waste materials must be transported to the disposal site, and especially in the case of long objects, there are many inconveniences such as the need for a large truck.
[0003]
For the treatment of such waste materials, a device called a crusher, a crusher or a bag breaker is used. However, since these devices cannot handle waste material exceeding the diameter of the rotary cutter, a device for mounting a larger cutter is required, and as a result, the device becomes larger and more expensive.
[0004]
A similar problem applies to automotive tires. Tire dealers always hold a large amount of old tires, and even if they are incinerated as fuel or reused as recyclable waste, they need to be finely ground. However, conventional processing devices, such as tire cutters, are not small enough to be placed in a corner of a store.
[0005]
[Problems to be solved by the invention]
The present invention has been made by paying attention to the above points, and an object thereof is to reduce the size of a waste cutting apparatus that can be used as a crusher, a tire cutter, or the like, and to enable on-site processing. is there. Another object of the present invention is to reduce the storage space for wastes and to make the transportation efficiency to an intermediate treatment facility or the like a factory.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, the present invention includes a pressurizing unit for crushing waste, and a cutting unit disposed adjacent to the pressurizing unit for cutting the crushed waste. Is provided so as to be able to move away from the setting location to set the waste and to crush the waste in the direction of the set location, and has a roller for feeding the waste while crushing the waste, and The means of cutting by the cutter of the cutting section is adopted.
[0007]
A waste cutting apparatus according to the present invention is for cutting waste having a hollow structure such as a tire or a pipe. It is recognized that waste having a hollow structure can be significantly reduced in volume by crushing and can be easily cut. The waste to be treated includes a polyethylene pipe used as the gas pipe, a vinyl chloride pipe used as a water pipe, a flexible pipe used for laying cables, and the like.
[0008]
Therefore, the cutting apparatus of the present invention includes a pressurizing unit for crushing waste and a cutting unit for cutting the crushed waste. The cutting part is arranged adjacent to the pressing part to immediately cut the waste crushed by the pressing part. This is because a tire or the like tends to return to its original shape immediately after being crushed, but by arranging a cut portion in the immediate vicinity of the pressurizing portion, waste can be cut before returning to the original shape.
[0009]
The pressurizing unit moves away from the setting position to set the waste, thereby increasing the distance d between the pressurizing units so that the waste can be set at the setting position and moving again in the direction of the set position to crush the waste. It is provided so as to narrow the interval. See FIG. 4 and FIG. The pressurizing unit has a plurality of rollers that move and squeeze the waste while sending it out, and sends out the waste that is sent out by the roller to the outlet of the pressurizing unit. The pressing unit can be configured by arranging a pair of rollers so as to be able to contact and separate from each other, but is not necessarily limited to this configuration.
[0010]
The roller may have a function of making a cut in a direction (vertical direction) in which the waste is crushed and sent out. For example, the edges on both sides of the roller serve as blades to push off the waste.For this purpose, it is necessary that the outermost part of the roller be configured so that the waste can be pushed in the pressing direction. is there. However, there is no particular need to provide a blade to push the waste in the feed direction.
[0011]
For example, it is preferable that the pressing unit includes an upper and lower roller group, and that the upper roller group is provided to be vertically movable with respect to the lower roller group. In this case, the upper roller group and the lower roller group each have a roller attached with an interval in the axial direction, and when approaching, the rollers of the upper roller group and the rollers of the lower roller group are axially engaged with each other. Alternately configured. That is, the waste is pressurized by being sandwiched between the upper roller group and the lower roller group, so that a cut is made. However, even though a break occurs, the break does not always have to occur, and the object of the present invention is still achieved. This is because, if a certain amount of vertical cuts can be made in the waste beforehand, the material finally cut by the cutting section will be cut more finely.
[0012]
A cutting cutter is provided at the outlet of the pressurizing unit to cut the waste crushed and sent out from the pressurizing unit. The cutter is arranged close to the outlet of the pressurizing section, so that the cutting process can be reliably performed even on waste such as a tire that is elastic and easily returns to its original shape. See FIG. 3, FIG. 4 and FIG. The cutter may be, but is not limited to, a wide shear, a so-called guillotine cutter-type push-off machine with a relatively long tooth extension.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the illustrated examples. The illustrated waste cutting apparatus 10 is configured in a vertical shape, and a pair of left and right base blocks 12 and 13 are provided on a base 11 and bearings 14 are provided respectively (FIG. 2). The shaft 15 has several rollers 16 constituting a lower roller group and is driven by a motor 17.

On the guide rods 18 and 19, slide blocks 20 and 21 are vertically moved along the guide rods. It is provided as possible. Each of the slide blocks 20 and 21 is provided with a bearing 22 which bears both ends of a shaft 23. The shaft 23 has several rollers 24 constituting an upper roller group, and is driven by a motor 25. Driven.
[0015]
The rollers 16 of the lower roller group and the rollers 24 of the upper roller group each have a gear shape, and are formed so as to be easy to bite into waste and to send out while crushing. Further, the roller 16 of the lower roller group and the roller 24 of the upper roller group are attached with an interval in the axial direction of each shaft 15, 23, and one roller 16 and the other roller 24 are staggered when approaching. (FIGS. 5 and 7). The interval between the pressurizing portions at the time of closest approach is -d. The axial length of the roller 16 in the lower roller group is set smaller than the length of the roller spacer 26, and this dimensional relationship also applies to the length of the roller 24 and the roller spacer 27 in the upper roller group. When the difference between the axial length of the rollers 16 and 24 and the length of the roller spacers 26 and 27 is reduced, a greater shearing effect is obtained. Each of the rollers 16 and 24 can be removed from the shafts 15 and 23, and the spacing and arrangement can be changed or replaced with another roller. Note that the rollers 16 and 24 can control the rotation direction and the like.
[0016]
Cylinder devices 30 and 31 are provided above guide rods 18 and 19 that guide slide blocks 20 and 21 to drive an upper roller group that is provided to be movable up and down with respect to the lower roller group.

Reference numeral 41 denotes a beam plate connecting left and right cylinder heads, and reference numeral 42 denotes a guard plate, which protects the guide rods 18 and 19. Therefore, the upper roller group, the cylinder devices 30 and 31 for moving the upper roller group up and down, and the lower roller group constitute a pressure unit 29 for crushing waste. In the illustrated example, the interval above the set point, which is indicated as the interval between the upper roller group and the lower roller group, can be changed from the interval + d for setting waste to the interval -d for crushing.
[0017]
The cutting part 45 is provided on the pressure part outlet side located on the back side of the main body (FIGS. 3 to 5). The illustrated cutting section 45 has a guillotine-type cutter 46. The cutter 46 descends from a lower frame 47 provided behind the lower roller group and presses the waste when the upper roller group is pressed.
