Problems solved by technology

The structure of the old-fashioned punching parts only moves up and down in the direction of thrust. A lot of debris will accumulate under the perforation. , causing a malfunction
Moreover, the debris overflows to the perforation table and disperses into the paper or device, causing problems such as machine operation errors
[0008] Second, as mentioned above, the piercing structure utilizes the thrust movement in the vertical direction, and the huge shearing force will increase the load on the drive motor when piercing.
When punching plastic folders or thick cardboard, the load on the drive motor will increase. It is necessary to use a large-capacity motor or slow down the punching speed, etc., causing the need to increase the size of the drive unit and increase the cost.

Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, the punching device of Embodiment 1 consists of an upper base 30 of the corresponding size to the plate to be punched, and a lower base 35 (also called "punching table") spaced between the upper base 30 and the perforated plate. 1. The punching part 40 installed on the upper base 30 and the punching 38 arranged on the lower base 35, the driving motor M, the transmission mechanism and the cam mechanism constitute the above-mentioned punching part 40 which is cylindrical and is provided with an upper shaft 421 And lower shaft 422, and be provided with punching knife 41 at its front end namely lower end, punching part 40 is provided with 2 or 3 or 4 etc. at intervals according to the specification (file hole specification) determined by upper base 30, this There are four in the embodiment: a first punching part 401 , a second punching part 402 , a third punching part 403 and a fourth punching part 404 .

[0040] The punching parts...

Embodiment 2

[0065] see Figure 18 to Figure 22 , Embodiment 2 is described as follows.

[0066] Figure 18 , Figure 19 The illustrated cylindrical cam 66 is fixed to the upper base 30 , and a guide pin 65 coupled with a cam groove 67 of the cylindrical cam 66 is provided on the punching member 62 side. In this embodiment, components having the same structure as those in Embodiment 1 are assigned the same numbers, and descriptions thereof are omitted.

[0067] Upper abutment 30 and lower abutment 35 with figure 1 The parts in the composition are the same, and the two form a whole. The drive shaft 60 connected to the drive motor M is configured on the upper base 30. In addition, the same as the first embodiment, the upper base 30 is provided with an upper guide rail 31 and a lower guide rail 32, and its upper and lower guide holes 311, 321 It is automatically fitted up and down with the piercing member 40 . Four perforating members 40 are arranged, as shown in the figure, which is th...

Embodiment 3

[0073] Such as Figure 23 As shown, the differences between Embodiment 1 and Embodiment 2 in Embodiment 3 will be described below. The structure of the perforating member 62 is basically the same as that of the second embodiment, so the same numbers are used, and descriptions are omitted. Figure 23 The sliding cam 82 shown replaces the eccentric cam 61 in the second embodiment, the sliding cam 82 is connected with the driving motor, and a cam groove 83 with a V-shaped groove 831 is provided on it. The cam groove 83 cooperates with the needle 832 on the top of the punching part 40, and the other structures of the punching part 62 are the same as those in the second embodiment.

[0074] Such as Figure 23 In the left-right direction shown, when the sliding cam 82 is operated back and forth through a given stroke, the pin 832 cooperating with the cam groove 83 moves from the upper apex of the V-shaped groove 831 to the lower apex, and moves to the thrust direction. The punchi...

Abstract

A cylindrical punch member equipped at the leading end thereof with a hole-punching blade is movably supported on a base frame in a hole-punching direction. A drive means is equipped that applies thrusting force to the punch member; a cam follower member disposed between the base frame and punch member engages a cam means disposed at either the base frame or punch member. An oblique cam surface inclined at a predetermined angle with regard to a hole-punching direction is equipped in cam means to give rotational drive force around an axis of rotation to the punch member that is moved in the hole-punching direction by the drive means. This configuration causes each of a plurality of cylindrical punch members to rotate around their axes of rotation when moved in a hole-punching direction by drive means thereby punching a hole in a sheet with a reduced shear force; the centrifugal force of that punch member rotation causing paper cutting debris to be scattered evenly under the punch member.

Description

technical field [0001] The invention relates to a perforating method and a perforating device for perforating paper printed by image forming devices such as duplicating machines, printing machines and printers. Background technique [0002] Generally, there are two methods for punching holes on the paper that needs to be bound: the manual method of punching holes on several sheets of paper with the punching part of an office punching machine; the method of automatically punching holes after printing by printing machines, copiers, etc. The former is a device that clamps the paper, sets the cylindrical punching part in the frame to move up and down, pushes down the operating lever, and penetrates the paper. On the contrary, the latter is a device that fixes the printed paper at the predetermined processing position in order, presses down the motor that drives the punching part to punch holes, and is assembled with other devices for use. These devices perforate at 2, 3 or 4 pl...
