ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is related to an improvement in the structure of a button transmission device for a button-sewing machine.
2. Description of the Prior Art
It has been found that the button-sewing machine generally utilizes a button transmission device to sieve out defective buttons. As shown in
FIG. 16
, the conventional button transmission device is simply a square tubular member
30
arranged between the oscillator
10
and the button-sewing machine
20
for preventing the passage of larger buttons (the smaller button is sieved out by the oscillator
10
). However, the square tubular member
30
is designed for the passage of a certain kind of button, and so the square tubular member
30
must be replaced with another one for a different kind of button thereby causing much inconvenience in use. Hence, it has been proposed to use an adjusting device
40
(see
FIG. 17
) to sieve out defective buttons, but it is still necessary to replace the square tubular member
30
with another one for a different kind of button when a different kind of button is to be sewed, thus still making it unfit for practical use.
Therefore, it is an object of the present invention to provide an improvement in the structure of a button transmission for a button-sewing machine which can obviate and mitigate the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
This invention is related to an improvement in the structure of a button transmission device for a button-sewing machine.
According to a preferred embodiment of the present invention, a button transmission device for a button-sewing machine generally includes a conveying device including two elongated sliding plates, a seat arranged between the two sliding plates, and a conveyor belt mounted on the seat, a positioner disposed above the seat, a puller arranged on one of the sliding plates and located against the positioner, a thickness adjuster arranged above the conveying device, and a positioning device provided with a stopper drivingly connected with a pneumatic cylinder, and a strip member mounted on an intermediate portion of the conveyor belt and having two sides higher than the conveyor belt to reduce friction between button and the conveyor belt.
It is the primary object of the present invention to provide an improved button transmission device for a button-sewing machine which can effectively sieve out defective buttons.
It is another object of the present invention to provide an improved button transmission device for a button-sewing machine which can be used for transmitting buttons with different specifications.
It is a further object of the present invention to provide an improved button transmission device for a button-sewing machine which is fit for practical use.
The foregoing objects and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
