Paper take-up mechanism and printing device using the same

The present disclosure relates to a paper take-up mechanism and a printing device using the same, and more particularly to a paper take-up mechanism having a pick-up arm and a printing device using the same.

In order to output and back up data, printing devices commonly used in daily life include printers, photocopiers, and fax machines. Among them, these printing apparatuses have a paper taking mechanism to facilitate paper separation of a plurality of sheets.

Currently, the printing device on the market limits the paper specifications that can be printed. For example, if the paper weight is 70~120gsm (gram per square meter), the paper can be smoothly taken one by one. However, at this time, if the user needs to use different paper characteristics such as paper having a paper weight of 200 gsm for printing, the printing apparatus is liable to cause the paper to be unloaded, and the printing is interrupted. Therefore, it has been necessary to develop a printing apparatus which can adjust based on the characteristics of paper to smoothly separate the sheets to prevent the occurrence of multiple sheets of paper feeding or paper stripping.

In view of this, the present disclosure relates to a paper take-up mechanism and a printing device using the same. Since the paper taking mechanism of the present invention can adjust the distance between the paper driving mechanism and the paperboard according to the characteristics of the paper, and avoid the occurrence of paper jam or paper tape, the convenience of the user is greatly increased.

According to a first aspect of the present disclosure, a paper take-up mechanism is proposed for paging a plurality of sheets of paper. The paper take-up mechanism includes a paperboard, a pick arm and a paperboard. The cardboard is used to carry the paper. The pickup arm has a paper driving mechanism. The paper driving mechanism abuts against the paper to drive the paper to move. The paperboard is placed on the moving path of the papers, and the papers are separated by the paperboard. Wherein, the distance between the paper driving mechanism and the paperboard is adjusted according to the characteristics of the paper.

According to a second aspect of the present disclosure, a printing apparatus is provided, comprising a paper taking mechanism and a printing mechanism. The paper taking mechanism includes a paperboard, a paper take-up arm and a paperboard. The cardboard is used to carry the paper. The pickup arm has a paper driving mechanism. The paper driving mechanism abuts against the paper to drive the paper to move. The paperboard is placed on the moving path of the papers, and the papers are separated by the paperboard. Wherein, the distance between the paper driving mechanism and the paperboard is adjusted according to the characteristics of the paper. The printing mechanism is connected to the paper taking mechanism for printing the papers that are removed by the divided cardboard.

In order to better understand the above and other aspects of the present disclosure, the preferred embodiments are described below in detail with reference to the accompanying drawings.

The present disclosure proposes a paper take-up mechanism and a printing device using the same. The paper picking mechanism is used to page a plurality of sheets of paper. The paper take-up mechanism includes a cardboard, a pick arm, and a paperboard. The cardboard is used to carry the paper. The paper take-up arm has a paper driving mechanism, and the paper driving mechanism abuts against the paper to drive the paper to move. The paperboard is placed on the moving path of the papers, and the papers are separated by the paper. Wherein, the distance between the paper driving mechanism and the paperboard can be adjusted according to the characteristics of the paper.

Please refer to FIG. 1 , which is a schematic view showing a first embodiment of a paper take-up mechanism according to the present disclosure. As shown in FIG. 1, the paper take-up mechanism 10 includes a paperboard 12, a paper take-up arm 14, and a paperboard 16. The carrier 12 is used to carry a plurality of sheets of paper 11. The pickup arm 14 has a paper driving mechanism 17. The paper driving mechanism abuts against the paper 11 to drive the paper 11 to move. The paperboard 16 is disposed on the moving path of the paper sheets 11, and the paper sheets 11 are separated by the paperboard 16 against the paperboard.

The paper driving mechanism 17 is spaced apart from the paperboard 16 by a distance d, which can be adjusted according to the characteristics of the paper 11, such as weight, thickness or material, so that the paper picking mechanism 10 can smoothly page the papers 11 .

The paper take-up mechanism 10 further includes an elastic member S. As shown in Fig. 1, the paper driving mechanism 17 is located at the first end 14a of the pickup arm 14, and the elastic member S is coupled to the second end 14b of the pickup arm 14. Since the elastic member S is connected to the second end 14b of the pickup arm 14, the reaction force generated by the paper driving mechanism 17 to drive the characteristics of the different paper sheets 11 can be appropriately adjusted, and the distance d between the paper driving mechanism 17 and the paperboard 16 can be appropriately adjusted. That is, since the elastic member S is coupled to the second end 14b of the pickup arm 14, the pickup arm 14 can elastically adjust the distance d between the paper driving mechanism 14 and the paperboard 16 in accordance with the characteristics of the paper 11.

For example, when the paper driving mechanism 17 exerts a force of about 50 grams on a tissue paper having a paper weight of 70 to 120 gsm (gram per square meter), the paper 11 can be smoothly moved, so that the paper 11 is made to interfere with the paperboard. 16 sorting paper. However, if the paper driving mechanism 17 is intended to drive a thick paper having a paper weight of 200 gsm, a force of about 200 gram is required to smoothly drive the paper 11 to move. Therefore, when the paper driving mechanism 17 is intended to drive a thick paper having a paper weight of 200 gsm, the initial force is insufficient to drive the thick paper having a paper weight of 200 gsm, but since the elastic member S is connected to the second end 14b of the paper take-up arm 14, it is moderate. The pick-up arm 14 is moved to increase the distance d between the driving mechanism 17 and the paperboard 16. When the distance d between the paper driving mechanism 17 and the paperboard 16 is increased to an appropriate distance, for example, when the reaction force generated by the elastic member S and the paper driving mechanism 17 is 200 grams, the paper 11 can be smoothly moved to the paperboard 16, The paper 11 is caused to be separated by the crepe paperboard 16. That is, the second end 14 of the pick-up arm 14 is connected by the elastic member S of the pick-up mechanism 10, so that the pick-up arm 14 can elastically adjust the distance between the paper-carrying mechanism 17 and the paperboard 16 according to the characteristics of the papers 11. d.

The elastic member S can be, for example, a compression spring, but is not limited thereto. The elastic member S that can elastically adjust the distance d between the paper driving mechanism 17 and the paperboard 16 according to the characteristics of the paper 11 is the disclosure. Within the scope of the disclosure.

Moreover, the paper taking mechanism 10 further includes a stopping portion P for blocking the paper taking arm 14 so that the distance d between the paper driving mechanism 17 and the paper dividing board 16 is not less than a predetermined distance, for example, not less than the paper driving mechanism 17 The distance that can drive paper with a paper weight of 70~120gsm. That is, the stopper portion P is used to return the pickup arm 14 to a position where the distance d is not less than a predetermined distance after the paper driving mechanism 17 finishes the thick paper having a paper weight of 200 gsm.

Further, the paperboard 12 is placed horizontally, and the paperboard 16 is placed at an angle θ with the carrier 12, for example, 118 degrees, to increase the probability that the paper 11 is paged.

Please refer to FIG. 2, which is a schematic view showing a second embodiment of the paper take-up mechanism according to the present disclosure. The second embodiment of Fig. 2 differs from the first embodiment of Fig. 1 in that the paper take-up mechanism 20 of Fig. 2 includes a first fixing portion 18a and a second fixing portion 18b. The first fixing portion 18a is for fixing the distance d between the paper driving mechanism 17 and the paperboard 16 to a first distance, for example, 1 to 2 cm. The first fixing portion 18b is for fixing the distance d between the paper driving mechanism 17 and the paperboard 16 to a second distance, for example, 4 to 6 cm.

Since the first fixing portion 18a fixes the distance d between the paper driving mechanism 17 and the paperboard 16 to a first distance, the paper driving mechanism 17 is closer to the paperboard 16. If the user wants to print a thin paper with a paper weight of, for example, 70 to 120 gsm, the paper 11 can be smoothly divided into 16 sheets of paper, thereby reducing the probability of multiple sheets.

Since the second fixing portion 18b fixes the distance between the paper driving mechanism 17 and the paperboard 16 by a second distance, the paper driving mechanism 17 is farther away from the paperboard 16, if the user wants to print a paper weight of, for example, 200 gsm thick paper. At this time, the paper 11 can be smoothly moved by the paper driving mechanism 17 one by one, greatly reducing the probability that the paper 11 cannot be fed. Therefore, since the paper taking mechanism 20 of the second embodiment includes a first fixing portion 18a and a second fixing portion 18b, the first fixing portion 18a or the second fixing portion 18b can be used to fix the paper according to the characteristics of the paper 11. The distance between the mechanism 17 and the paperboard 16 is d, which reduces the situation in which multiple sheets of paper are fed or the paper is not taken up.

The first fixing portion 18a and the second fixing portion 18b can be realized by an engaging member, but are not limited thereto. Embodiments that can be used to fix the distance between the paper-carrying mechanism 17 and the paperboard 16 to a specific distance are within the scope of the disclosure.

In addition, the paper take-up mechanism 20 of the second embodiment of the present disclosure includes a first fixing portion 18a and a second fixing portion 18b, but is not limited thereto. The paper picking mechanism 20 further includes a third fixing portion or a fourth fixing portion to meet the needs of the user.

Referring to FIG. 3, there is shown a schematic view of a printing apparatus to which the paper take-up mechanism 10 of the first embodiment or the paper take-up mechanism 20 of the second embodiment is applied. As shown in Fig. 3, the printing apparatus 1 further includes a printing mechanism 30 which is connected to the paper taking structure to print the paper 11 which is removed by the paperboard 16.

In summary, since the paper take-up mechanism of the present disclosure and the distance between the paper driving mechanism and the paperboard of the printing device using the same can be adjusted according to the characteristics of the paper, the paper weight can be printed according to the user's demand. 70~120gsm thin paper or 200gsm thick paper reduces the chance of multiple sheets or papers, which greatly increases the convenience of users.

In conclusion, the present invention has been disclosed in the above preferred embodiments, and is not intended to limit the present invention. A person skilled in the art can make various changes and modifications without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
