Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a vegetable binding machine for binding vegetables such as spinach or burdock into a bundle with tape.

"Prior Art" Conventionally, as shown in Japanese Unexamined Patent Publication No. 55-126008, there is a technology for binding vegetables with binding tape, which is equipped with a binding arm that feeds out and supports the binding tape, a tape clamping lever that clamps the tip of the binding tape, etc. It was hot.

"Problems to be Solved by the Invention" The above-mentioned conventional technology constantly connects an electric motor to the oscillating binding arm via a chain, and
Since the electric motor was connected to the tape wheel shaft supporting the binding tape via a chain and an electromagnetic clutch, it was not possible to easily downsize and simplify the electric motor binding drive system and reduce manufacturing costs. It is difficult to handle the operation timing adjustment using many switches such as forward/reverse and on/off of the electromagnetic clutch, and the tape clamping lever cannot be easily forcibly driven by an electric motor. There were some problems, such as not being able to do it easily.

Furthermore, as shown in Japanese Patent Application Laid-Open No. 54-24199, there was a technique to provide an arm lifting/lowering cam plate for swinging the binding arm, but since the arm lifting/lowering cam plate was connected to the electric motor via a clutch plate, This is because the connecting structure between the cam plate and the motor cannot be easily simplified, and the structure is such that a pair of rollers for rewinding the binding tape is provided in the middle of stretching the binding tape, and the binding tape is sandwiched between the pair of rollers. , it is not possible to use binding tape with an adhesive surface,
Since the binding is done only by fusing the binding tape, there is a problem in that it is not easy to obtain the appropriate binding force of the binding tape, and, like the above-mentioned conventional technology, the binding clamp lever cannot be easily forcibly driven by an electric motor. There were other problems.

``Means for solving the problem'' However, the present invention integrates a stop cam plate, a binding operation cam plate, an arm elevation cam plate, and a tape tension cam plate on the same axis as the gear that is constantly connected to the electric motor. On the other hand,
A stop lever that operates the electric motor in conjunction with the detachment operation is detachably engaged with a stop cam plate, and a binding operation cam plate is connected via a link to a tape clamping lever that clamps the tip of the binding tape. At the same time, a swing cam is provided on the arm elevating cam plate to be connected to the binding arm that feeds and supports the binding tape and swings the binding arm, and a swing cam is provided on the arm elevating cam plate to unwind the binding tape during the binding forward movement of the binding arm. The present invention is characterized in that the above-mentioned tape tension cam plate is provided with a tension cam that connects the binding tape to the tape wheel shaft that supports the binding tape.

"Function" Therefore, since the stop cam plate is provided, the driving of the electric motor can be properly stopped with a simple structure, and since the bundling operation cam plate is provided, the leading end side of the bundling tape can be supported by forcibly driving the tape holding lever. The functions can be easily improved, and since the arm lifting/lowering cam plate for swinging the binding arm is always connected to the electric motor through a gear, the binding arm drive structure can be simplified and the manufacturing cost can be easily reduced. Since a tape tension cam plate is provided that drives the tape wheel shaft to rewind, the structure for rewinding the binding tape can be simplified and binding tape with an adhesive surface can be used more easily than in the past. Since the other cam plates are integrally provided on the same axis as the plate, the multiple operations necessary for the binding operation using the binding tape can be performed at the appropriate timing, eliminating the need for troublesome operation timing adjustments and simplifying the binding drive structure. It is possible to improve the handling and operability such as assembly and disassembly more easily than before.
