Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crushing device for crushing syringes, infusion containers, etc.

BACKGROUND ART Conventionally, as the above-mentioned crushing apparatus, for example, the one shown in FIG. 5 is known as an apparatus for crushing small objects such as syringes. This crushing device has a pair of rotating shafts 11, 11 spaced apart from each other. These rotating shafts 1
1 and 11 are provided with cutters 12 and 12 which are disc-shaped and have protrusions on their outer peripheries, and are arranged with their outer peripheries overlapped with each other. Then, the cutters 12, 12 are rotated, and the syringe T, etc. is sandwiched between the two cutters 12, 12 and crushed. Further, as a crushing device for crushing large objects, for example, the one shown in FIG. 6 is known. This crushing device also has a pair of rotating shafts 21, 2.
1, a disc-shaped cutter 22 with a protrusion on the outer periphery;
22 is provided, and these two cutters 2
2 and 22 sandwich the infusion container B and crush it.

Further, as an apparatus that can be used for both small and large objects, there is known, for example, the one shown in FIG. 7. This crushing device has a disk 32 provided on a shaft 31, and this disk 32
Arm portions 33 projecting radially outward on the outer periphery of...
is provided. This pulverizer rotates the disk 32 and the arm 33 at high speed to crush the input object with the impact force of the arm 33, and it can crush small objects such as syringes and other objects. It is now possible to crush even large objects such as infusion containers.

[Problem that the invention attempts to solve]

By the way, although the crushing device shown in FIG. 5 above can crush small objects such as syringes,
For large items such as infusion containers, cutter 1
It cannot be rolled up between 2 and 12 and cannot be crushed. Further, the crushing device shown in FIG. 6 can crush large objects such as infusion containers, but cannot crush small objects such as syringes because they fall through the gap in the cutter 22. For this reason, when crushing small to large objects, both devices are required, which poses a problem in that extra costs and installation space are required.

On the other hand, a crusher as shown in FIG. 7 can crush both small and large objects. However, since it is pulverized by the impact of high-speed rotation, there is a problem in that it is too noisy and cannot be used indoors such as operating rooms and research laboratories. In particular, such crushing devices are often used in hospital operating rooms, laboratories, etc. to crush used syringes, infusion containers, etc. on the spot to prevent reuse and infection. Therefore,
Although quietness is required, this device cannot be used in these locations due to its high noise.

The purpose of the present invention is to solve these problems and provide a crushing device that can crush small to large items, takes up a small amount of space, and has low noise.

[Means for solving problems]

The present invention was devised to solve the above problems, and includes a pair of fixed blades each having groove surfaces having an arcuate cross section and arranged parallel to and spaced apart from each other, and a space between the two fixed blades. a rod-shaped stopper disposed parallel to the fixed blades and equidistantly spaced from the fixed blades; A pair of rotary blades that rotate around the stopper and have an arcuate cross section and are provided with a diameter slightly smaller than each of the groove surfaces, and are provided below both of the fixed blades and are arranged parallel to and spaced apart from each other. A pair of rotating shafts and a plurality of disc-shaped cutters arranged at a distance from each other in the axial direction are provided on each of the two rotating shafts, and these cutters have a plurality of protrusions protruding outward on the outer peripheral surface of the cutters. The cutter having a blade and provided on the one rotating shaft and the cutter provided on the other rotating shaft are arranged so that their outer peripheries overlap each other.

[Effect]

According to the present invention, a large object to be crushed can be first crushed into small pieces by a pair of fixed blades and a rotating rotary blade, and then crushed into fine pieces by being sandwiched between multiple cutters, so a single device can crush the object. , it is possible to grind from small to large objects. Therefore, the installation space for the device can be reduced, and the cost of the device can be reduced. Further, since it is possible to crush objects ranging from small to large sizes without rotating the rotary blade and cutter at high speed, the noise of the device can be reduced. Therefore, it can also be used in operating rooms, laboratories, etc. where quietness is required.
