Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a feeding device for shredded objects in a shredder that shreds documents to be disposed of.

[0002]

[Prior Art]

 A shredder is a device in which a pair of rotary blades catch and shred objects to be shredded between the blades and shred them, but especially in the case of rolled paper, the size is larger than the radius of the rotary blades. If it gets loose, it may loosen on the pair of rotary blades and may not be caught between the blades.

In order to improve such a state, an inverted V-shaped distribution plate interlocking with the rotary blade is provided (No. 57-10761), or a pushing plate interlocking with the rotary blade is provided (No. 58). -33790).

However, in these devices, since the rotary motion of the rotary blade is changed to swing motion through the crank, it is intermittent to bite the shredded object into the rotary blade. For this reason, the rotary blade intermittently pushes in a large amount of shredded objects. Therefore, the load applied to the rotary blade becomes intermittent, which hinders smooth shredding work and causes a failure for the shredder that tries to rotate at a constant speed.

[0005]

[Problems to be solved by the device]

 In order to eliminate the above-mentioned drawbacks, in the present invention, a rotary shaft is provided on the upper stage of the rotary blade shaft and a plurality of blade-shaped pushing plates are attached, and the rotary blade shaft is rotated simultaneously in the same direction via an intermediate gear. By doing so, the object to be shredded can be continuously supplied to the rotary blade.

[0006]

[Means for Solving the Problems] Support plates (3) and (3) are provided on both inner surfaces of the upper stage of the shredder main body (1) provided with an input port (2) for shredded objects, and the support plate is used for the lower stage of the input port. The shafts (6) and (7) of the pair of rotary blades (4) and (5) are supported on the rotary blade shaft, and the rotary shaft (8) is erected on the upper stage of the rotary blade shaft. Install 9). Gears (10) and (11) that mesh with the rotary blade shafts (6) and (7) are attached, gears (12) attached to the shaft end of the rotary shaft (8) and gears (10) attached to the rotary blade shaft. An intermediate gear (13) meshing with and is provided to rotate the rotary blade shaft and the rotary shaft having the pushing plate in the same direction at the same time. The transmission gear (14) is attached to the shaft end of the rotary blade shaft (6), and the rotation of the driving gear (16) is transmitted via the chain (15).

It should be noted that if a protective cylinder (17) with upper and lower openings is attached to the upper edge of the main body (1) so as to be openable and closable, scattering and danger of shredded objects can be prevented, and a transparent plate can be placed in front of the cylinder. It is convenient to provide (18) because the inside can be seen through.

[0008]

[Action]

 When the electric motor (M) is rotated by a switch operation (not shown), the driving gear (16) rotates and the transmission gear (14) rotates via the chain (15). Since the transmission gear is attached to the rotary blade shaft (6), the pair of rotary blades (4) and (5) rotate via the gears (10) and (11). At this time, the rotary shaft (8) to which the pushing plate (9) is attached also simultaneously rotates in the same direction as the rotary blade shaft (6) via the intermediate gear (13). When the object to be shredded (19) is inserted from the upper end of the protective cylinder (17), it is pushed into the rotary blades (4) and (5) by the pushing plate (9) and continuously shredded to form a waste box in the main body. It is dropped (not shown) and stored.

[0009]

【Example】

 With reference to the drawings, an embodiment will be described with reference to FIG. 1 and FIG. 2. Support plates (3) and (3) are provided on the inner surfaces of both sides of the shredder main body (1) provided with an inlet (2) in the upper stage, and the support plate The shafts (6) and (7) of the pair of rotary blades (4) and (5) provided in the lower stage of the insertion port are supported, the rotary shaft (8) is installed above the rotary blade shaft, and a plurality of blade-shaped indentations are made on the shafts. Install board (9). The gears (10) (11) that mesh with the rotary blade shaft are attached respectively, the gear (12) is attached to the shaft of the pushing plate, and the intermediate gear (13) that meshes with the gear (10) and the gear (12) is attached. The transmission gear (14) is attached to the shaft end of the rotary blade shaft (6) on one side so that the rotation of the driving gear (16) is transmitted through the chain (15). A protective cylinder (17) having upper and lower openings is attached to the upper edge of the main body so as to be openable and closable, and a see-through plate (18) is provided on the front side.

[0010]

[Effect of the device]

 As shown in the above configuration, the rotary blade shaft and the rotary shaft to which the pushing plate is attached rotate at the same speed. Therefore, the object to be shredded is surely fed at a constant speed, and the rotary blade surely shreds this at a constant speed, which is very efficient. In addition, since a protective cylinder is installed in the upper part of the main body, shredded materials do not scatter and the pushing plate is not touched by the hand, which has the advantage of preventing danger.
