Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a material supply device for a press device for punching individual pieces from a plate material.

<Prior Art> Conventionally, when punching a plate material with a press, the material was manually moved or moved by a feed claw device. However, for example, when punching a product from a plastic sheet such as a cash card or the like, which is printed on paper, it is necessary to perform high-precision positioning in order to prevent misalignment with the printing portion, which is not possible manually. In addition, in the case of the feed claw device, it is necessary to separately form holes for feeding the feed claws at equal pitches, the mold becomes large, and moreover, a space for installing a complicated feed claw mechanism in the press is also required, and the capacity is reduced. Needed a big press. Moreover, in the case of punching with an equal pitch feed like a feed claw device, there is a defect that an incomplete punching portion is generated.

<Purpose of the Invention> In order to solve the above-mentioned drawbacks, the present invention locates a material on a pitch feed roller of a press machine which punches a plate material by one or two kinds of pitch feed, and positions it by the device. Therefore, it relates to a device for supplying a fixed position.

The registration device referred to in the present invention means that the short plate is first sent in one direction and applied to a stopper to stop, and then sent in a direction perpendicular to the one direction and applied to another stopper to stop. The clamping device is a device that performs a step before the step of gripping the short plate. The term "registration portion" as used in the present invention refers to both the stoppers.

<Structure of the Invention> The present invention performs a series of operations of positioning a plate material with a register device, holding it with a clamp device, and feeding it to a pitch feed roller of a press at a fixed position with an intermittent drive device. It is configured to move in synchronism with the press by mechanically interlocking with the clamp axis of the press. That is, according to the present invention, in a device for supplying a fixed position to a pitch feed roller of a crank press device for punching a short plate (hereinafter abbreviated as a plate) by a pitch feed method, the number of punches in the press direction of the plate is n, and a crank for driving a press ram. The speed reduction mechanism that reduces the speed from the shaft to 1 / n or 1 / n + 1 and the register for positioning the output shaft of the speed reduction mechanism and the short plate can be saved when the short plate is sent to the press. The input shaft of the register device and the input shaft of the clamp device that opens and closes in the thickness direction the members arranged above and below to grip the short plate are fed to the pitch feed roller of the crank press device at a fixed size. A short plate punching characterized in that the crankshaft of the press and the retractable register device move in conjunction with each other by being connected to the input shaft of the intermittent drive device. There is provided a press apparatus.

<Example> The present invention will be described below with reference to an example.

Referring to FIG. 1 and FIG. 3, a connecting shaft 3 is mounted coaxially with an output crank shaft 2 of a crank type press body 1, and a pulley 5 is provided so that a reduction ratio of 1 / n or 1 / n + 1 can be obtained from a timing pulley 4. Is transmitted to the pulley 7 via
Input to the intermittent drive unit 8. As shown in FIG. 4, the relationship between the input shaft 8a and the output shaft 8b of the intermittent drive unit 8 is that the output shaft has constant angle rotating parts 49 and 50 and the stationary part 5 for one rotation of the input shaft.
Having one. At this time, the directions of rotation of 49 and 50 are opposite to each other.

A swing arm 9 is fixed to the output shaft 8b, a rotary link plate 10 is attached via a bearing, and a rotary link plate 11 is similarly attached to the tip end of the swing arm 9 via a bearing. There is. This rotating link plate 10,11
Are connected by a rod 12 so as to form a parallel link. A cam 13 is fixed to the other end of the input shaft 8a of the intermittent drive unit 8, and the displacement of the cam 13 is received by a cam follower 14, and a rotary link plate is connected via a connecting rod 15 link arm 16 and a connecting rod 17. Communicate to 10.

Similarly, from the timing pulley 4 to the reduction ratio 1 / n or 1 / n + 1
Is transmitted to the pulley 20 via the pulleys 5 and 19 and is also input to the cam shaft 21. The cam shaft 21, the cam plates 22, 23,
The barrel cams 24, 25 are fixed, and the displacement of the cam plate 22 causes the cam follower 26 to rotate the front contact portion 28 via the receiving connecting rod 27. The displacement of the cam plate 23 depends on the cam follower.
Received at 29, connecting rod 30, link arm 31, connecting rod 32
The horizontal pad portion 33 is rotated via. The displacement amount of the barrel cam 24 is received by the cam follower 34, and the roller 36 is rotated via the shaft 35. The cam follower 37 rotates the roller arm 39 via the receiving shaft 38 to change the position of the barrel cam 25. A roller 40 is attached to the tip of the roller arm 39.

The finger 41 for gripping the sheet is biased in a direction to be closed by a spring 43 around a rotation fulcrum 42. The finger 41 is attached to a block 44, and the block 44 is directly moved by a slide rail 45. block
A rotary link plate 46 is attached to the shaft 44 via a bearing, and forms a parallel link with the rotary link plate 11 via a connecting rod 47. When the swing arm 9 rotates,
The block 44 moves linearly on the slide rail 45 by the connecting rod 47. Further, the cam follower 14 is rotated by the cam follower 14 via the receiving connecting rod 15, the link arm 16, and the connecting rod 17 to rotate the rotary link plate 10. When the rotary link plate 10 rotates, the rotary link plate 46 is rotated via the rotary link plate 11 by the action of the parallel link. The cam follower 4 is attached to the rotary link plate 46, and the cam follower 48 is configured to move so as to contract the spring 43 by the rotation of the link plate 46.

The registration device, as shown in FIG.
It is sent in the direction of 49 and applied to one front contact portion 28 of the registration portion (stopper) and stopped. Next, the rollers 36, 40 (first
(See Fig. 3 and Fig. 3), the plate is sandwiched and rotated, and it is sent in the direction 50, which is perpendicular to the direction 49, and applied to the other lateral contact part 33 of the register part (stopper). Stop. With the above, positioning of the plate at the predetermined position is completed. Then, the fingers 41 are closed to grip the plate. Next, the swinging arm 9 is rotated by a constant angle (49) by the intermittent drive device, and the pitch feed roller of the press is fed at a fixed size when the roller is open. When the swing arm is stopped (51), the pitch feed roller is closed, the fingers 41 are opened, and the swing arm 9 is again rotated by a constant angle (50).
Return to the original position. Here, when the plate material and the fingers 41 move, the front abutment portion 28 and the side abutment portion 33 must move to a position where they do not interfere, and the rollers 36, 40 must also be open. These series of movements are carried out by transmitting the displacement amount of each cam by a link device, but all the cams are driven by the crankshaft of the press and move in synchronization with the movement of the press.

<Effects of the Invention> As described above, according to the present invention, it is possible to supply a plate material positioned by registering to the pitch feed roller of the crank press device at a fixed position in synchronization with the press.
