Abstract

A roller wheel baler and in particular to one which may be used to tie up an article is operated by turning a handle 2 to actuate an engaging plate 3 so as to rotate a ratchet wheel 8 which in turn drives a transmission roller 7 to draw in the tape binding around the article; further. A serrated plate 9 prevents the tape binding around the article from loosening. If it is desired to loosen the tape, the engaging plate is separated from the ratchet wheel and the serrated plate lifted. <IMAGE>

Description

SPECIFICATION Roller wheel baler The present invention relates to a roller wheel baler and in particular to one which may be used to tie up an article by turning a handle to actuate an engaging plate so as to rotate a ratchet wheel which in turn drives a transmission roller to draw in the tape binding around the article.

The conventional method for binding an article or the like is simply achieved by human labor, but it has some serious drawbacks which are described as follows: 1/. It is difficult to tie up an article tightly.

2/. It is easy to hurt the hands of the operator.

3/. It is time-consuming to tie up an article tightly.

4/. It is impossible to tie up an article very tightly.

5/. It is impossible to prevent the tape binding around an article from loosening.

Heretofore, a known binding device has been developed, but it still has some defects.

As shown in Fig. 4, the tape used to tie up an article is first inserted through a slot of a shaft and then wound up on the shaft. Since the space formed among the shaft, the engaging plate and the base is not large enough, the tape is unable to be drawn in after it has been wound around an article made of cotton, cloth or the like a few turns; that is to say, the article cannot be tied up tightly and thus may cause accident.

It is a primary object of the present invention to provide a roller wheel baler which may tie up an article with a tape just by moving a handle up and down.

It is another object of the present invention to provide a roller wheel baler which may prevent the tape tying up an article from loosening by means of a serrated plate.

It is still another object of the present invention to provide a roller wheel baler which may be directly fixed to the article.

Other objects and a fuller understanding of this present invention will be obtained by those skilled in the art when the following detailed description of the best mode contemplated for practicing the invention is read in conjunction with the accompaying drawings wherein like numerals refer to like or similar parts and in which: Figure 1 is a perspective view of a roller wheel baler of a preferred embodiment according to the present invention; Figure 2 is a perspective view showing the operation of the roller wheel baler according to the preferred embodiment of the present invention; Figure 3 is front view showing the operation of the roller wheel baler according to the preferred embodiment of the present invention; and Figure 4 is a perspective view of a known binding device.

Certain terminology will be used in the following description for convenience in reference only and will not be limiting. The words "lower" and "higher", "rightwardly" and "leftwardly" will designate directions in the drawings to which reference is made. Said terminology will include the words above specifically mentioned derivatives thereof and words of similar import.

Referring to the drawings and particularly to Fig. 1, the present invention comprises a main body portion (1), a handle (2), an engaging plate (3), a fixed shaft (5), a movable roller (6) and a transmission roller (7). The fixed shaft (5) is fixed on the lower part of the main body portion (1). The transmission roller (7) is mounted on the upper part of the main body portion (1). Adjacent to the transmission roller (7) is the movable roller (6) which is mounted on the main body portion (1) by inserting a shaft (10) (as shown in Fig. 3) into slots (13) of the main body portion (1) so that the movable roller (6) will slide down the slots (1 3) to get into touth with the transmission roller (7). Each end of the transmission roller (7) is provided with a notch (20) into which is inserted a ratchet wheel (8) which is fixed by a pin (30).As a result, the ratchet wheel (8) will rotate with the transmission roller (7) simutaneously. The engaging plate (3) which is mounted on two arms (40) of the handle (2) is provided with two protuberances (50) each of which is inserted between two teeth of one of the ratchet wheels (8). At the lower part of the main body portion (1) is a serrated plate (9) which concaves upwards and is equipped with a spring (11). The serrated plate (9) is normally in contact with upper half part of the fixed shaft (5), so that the tape will pass through the clearance between the serrated plate (9) and the fixed shaft (5).Since the serrated plate (9) is spring loaded, the teeth of the serrated plate (9) are normally forced by the spring (11) to press on the upper half part of the fixed shaft (5); in this way, the tape therebetween can pass in one direction only (i.e., in the direction to draw in the tape).

Moreover, on the right side of the main body portion (1) is mounted a fixed rod (4) on which the tape is fastened.

Referring to Fig. 3, there is shown the operation of the improved binding device according to the present invention. To use the improved binding device according to the present invention, first fix one end of the tape (14) to the fixed rod (4). Then tie up the article with the tape, pass the other end of the tape through the clearance between the serrated plate (9) and the fixed shaft (5), wind around the movable roller (6), and then pass through the distance between the movable roller (6) and the transmission roller. Then pull out the tape from the bottom of the engaging plate (3). Lift up the handle (2), thereby moving the engaging plate (3) which in turn drives the ratchet wheels (8) to rotate in the direction (L).Since the ratchet wheels (8) are fixedly engaged with the transmission roller (7), the transmission roller (7) will rotate with the ratchet wheels (8) in the direction (L). The transmission roller (7) successively drives the movable roller (6) to rotate in reverse direction (R). In consequence, the tape (14) will be drawn in and the article will be tied up tightly.

As the article is tied up tightly, the movable roller (6) will be forced to slide down the slot (3) by three kinds of forces; the first one is the reaction force of tape binding around the article, the second one is the force pulling on the tape (14), and the third one is the weight of the movable roller (6). Move down the handle (2) to its initial position. Repeat the operation again and again until the article is tied up tightly. To untie the tape (14), first separate the engaging plate (3) from the ratchet wheels (8) and lift up the handle (2), so that the engaging plate (3) is fixedly engaged in two notches (12) positioned at the top of lugs (70) of the main body portion (1).

Then lift up the serrated plate (9), thereby releasing the tape (14).

Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present disclosure has been made by way of example only and that numerous changes in the detail of construction and the combination and arrangement of parts thereof may be resorted to without departing from the scope and spirit of the invention as hereinafter claimed.
