Description

Roller protector for business machines

The invention relates to a protection device for a roller of a transaction machine; in particular to a paper feed roller for a transaction machine (for example, a printer, etc.), which protects the roller from being contaminated by suspended particles when not in use, minus To the least means.

It is a well-known technique to apply an automatic paper feeding device that allows paper documents to be printed or scanned in a transactional machine. Conventional paper feeders are typically equipped with rollers for feeding paper or documents into a transaction machine or for distribution within a transaction machine. For example, when the printer's roller or paper feed roller performs the printing of the paper, it uses the friction between the roller and the paper to bring the paper into the printer; however, as those familiar with the art know, The roller will be attached by foreign matter such as dust or aerosol, which causes the frictional force mentioned above to gradually decrease, causing the paper feeding or paper feeding of the roller to be inaccurate or even disappeared, and this situation is not what we expect. of.

In order to improve the above problems, the prior art has also disclosed a concept of applying a brush to scrape off contaminants adhering to the roller; for example, Taiwan No. 93120988 "Roller device with clean functional structure" is provided A typical embodiment. The brush is arranged on the frame of the roller, and is in contact with the roller; the roller is used to achieve the cleaning roller when the roller is in motion.

Typically, these references show relevant design techniques for paper feeders in terms of transactional machines; they also reflect some of the problems with these paper feeders in certain applications. If the redesign considers the paper feeding device to make it different from the conventional one, it will change its usage and operation. As a situation, it is different from the old law. Compared with the concept of applying the brush cleaning roller in the prior art, the present invention attempts to provide a design protection mechanism in the roller device, which can automatically close the roller when the roller is not in use, or when the roller is in use. The mechanism of automatically opening the roller to minimize the attachment of the roller to dust or suspended particles is minimized; and such subject matter is not shown or specifically disclosed in the above reference.

Therefore, the main object of the present invention is to provide a roller protection device for a transaction machine, comprising a base frame, a reciprocating actuator arm disposed on the base frame, and a roller cover; Responding to the reciprocating motion of the actuating arm, moving between a first position and a second position to open or close the roller; and an elastic element is disposed between the actuating arm and the cover, and constantly The cover is in the first position of the open roller. However, when the roller is not in use, a protection mechanism is established to allow the cover to automatically close the roller, so that the suspended particles contaminate the roller is minimized.

According to the roller protection device of the transaction machine of the present invention, the elastic member has a first end and a second end, respectively embedded in one shoulder of the actuating arm and the cover, so that the cover is constantly positioned Open the first position of the scroll wheel.

According to the roller protection device of the transaction machine of the present invention, the cover has a convex portion or a pin which interferes with the base frame when the actuator is double-acting, forcing the cover to close the roller to the second position.

The novelty, features, and other objects and effects of the present invention will be hereinafter described in conjunction with the detailed description of the drawings, as illustrated.

Please refer to Figures 1 and 2 for the roller protector of the transaction machine of the present invention. A pedestal is generally indicated by reference numeral 10; the pedestal 10 has a pivoting portion 11 for pivoting an actuator arm 20. In the embodiment taken, the actuator arm 20 has a pivoting portion 21 for pivoting with the pivoting portion 11 of the base frame 10 and forming the actuator arm 20 in a reciprocable or oscillating configuration.

The actuator arm 20 also has a fitting portion 22 for fitting a roller (or paper feed roller) 30. In the embodiment of the present invention, the fitting portion 22 has a convex portion or shaft 23 for pivotally connecting a cover 40 so that the cover 40 can respond to the reciprocating motion of the actuating arm 20 at a first The position is moved between a second position to open or close the roller 30. The first and second figures also show that the cover 40 has a projection or pin 41. When the actuator 20 is moved back or doubled toward the base 10, the projection or pin 41 and a base 41 are disposed on the base 10. The wall 12 creates an interference that forces the cover 40 to close the roller 30 to the second position (this portion will be described later).

An elastic member 50 is disposed between the operating arm 20 and the cover 40; specifically, the elastic member 50 is sleeved on the convex portion or the shaft 23 of the actuator fitting portion 22, and has a first end 51. The shoulder portion 24 is formed in a fitting portion 22; and a second end 52 is fixed to the shell cover 40, and the shell cover 40 is constantly positioned in the first position of the open roller 30.

Please refer to Figures 3 and 4 for the case where the actuator arm 20 reciprocates. Figure 3 shows the position of the actuator 20 in the forward movement (moving to the right in the figure) when the roller 30 is performing the paper feeding or paper feeding operation; at this time, the cover 40 is due to the elastic member 50 The limit is in the first position of the open scroll wheel 30. When the roller 30 is finished performing the paper feeding or the paper feeding operation, the actuator 20 is returned or double-shifted to the left in the figure, and the convex portion or the pin 41 of the cover 40 will be like the one shown in FIG. The wall 12 of the frame 10 creates interference.

Please refer to Figure 5, as the boom 20 continues to swing to the left in the figure, the wall The interference with the cover projection or pin 41 forces the cover 40 to rotate toward the second position, compressing the resilient member 50 to accumulate energy; until the cover 40 closes the roller 30, such as the one shown in FIG. It can be understood that if the actuator arm 20 moves or swings to the right in the figure, the interference state of the cover protrusion or the pin 41 and the wall 12 is released, and the elastic member 50 releases the previously accumulated energy, forcing the cover 40. Moving toward the first position of the open roller 30, such as the position shown in FIG.

Therefore, when the roller 30 performs the paper feeding or paper feeding operation, the cover 40 automatically opens the roller 30; when the roller 30 is in the non-use state, a protection mechanism is established, so that the cover 40 can automatically close the cover 30. The roller 30, which allows the aerosol to contaminate the roller 30, is minimized.

Typically, the roller protector of this transaction machine has the following considerations compared to the prior art:

1. The spatial pattern is significantly different from the conventional structure compared to the design of the art and structural type of the conventional roller device.

2. Compared to the concept of applying the brush cleaning roller in the old method, the roller device design provides a protection mechanism for automatically closing the roller 30 when the roller 30 is not in use, or when the roller 30 is in use. The wheel 30 is automatically opened.

However, the above is only a possible embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent variations and modifications made by the scope of the present invention are covered by the scope of the present invention. .
