Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a switch for starting a binding machine for vegetables, etc.

(Prior Art) Conventional starting switches for tying machines include those disclosed in Japanese Utility Model Application No. 59-159503 and Japanese Utility Model Application No. 59-159504. In the former, starting switch push plates with various planar shapes are prepared and can be replaced with any planar shape, and in the latter, the position of the starting switch push plate can be changed depending on the machine of the binding machine. It is made to be interchangeable on the left and right sides of the stand.

However, in either case, the starting switch has a predetermined mounting structure and its mounting position is determined at a predetermined position, so it is only necessary to change the shape of the switch push plate or change the installation position from side to side. That's not enough. For example, vegetables vary in size and shape, with some being round and others long and thin depending on the type. In many cases, changing the shape of the board cannot solve the problem. In this case, it may be possible to move the switch to the left or right, but it is difficult to operate the switch on the side that is not the dominant arm.

(Technical problem of the invention) This invention solves the above-mentioned drawbacks and proposes a starting switch for a binding machine that can be installed at any position without being restricted by the location, direction, etc. of the binding machine itself. Consider it a technical issue.

(Means for Solving the Problems) In order to solve the above problems, a starting switch for a tying machine according to the present invention is a switch for starting a drive section of a tying machine. The switch button of the switch is exposed, and a magnet is attached to the lower surface of the switch box, while the switch box and the drive section of the binding machine are formed respectively on the machine base on which the switch box and the drive section are provided. It is characterized by being connected by a connecting cord through a cord passing hole.

(Operations and effects of the invention) As described above, according to the invention, a magnet is attached to the bottom surface of the switch box that houses the starting switch of the binding machine, and the base of the binding machine is made of iron. By adsorbing the magnet to the machine base, the switchbox can be moved anywhere, in any direction, within the length of the connecting cord, depending on the shape and size of the object to be bound.
It can be installed anywhere that is convenient for the worker. In this way, since the installation position of the switchbox can be freely selected and changed, the work efficiency of the bundling work is improved and the practical effect is great.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

Symbol A indicates a binding machine. This binding machine A has a binding tape holder 2 and a support stand 3 arranged in front and back on a steel machine stand 1, and a front support shaft 4 of the support stand 3 has a tip that swings up and down above the tape holder 2. The guide arm 5 of the binding tape 4 is supported swingably, while the roll part 4a of the binding tape 4 has an adhesive layer on one side at the rear.
The binding tape 4 is rotatably supported, and the binding tape 4 unwound from the roll portion 4a is arranged from the roller 7 on the support 6 to the tip guide surface 5a of the guide arm 5, and the tip 4b of the binding tape 4 is placed on the tape receiver. At the same time, the guide arm 5 is attached to the binding tape pedestal 2 by a drive device of a drive unit provided on the machine pedestal 1.
By swinging it up and down, the object to be bound 8 placed between the binding tape receiver 2 and the support base 3 is bound from the front of the machine base 1.

As shown in FIG. 2, the drive device includes an electric motor 9, a rotating plate 10 operatively connected to the output shaft of the motor 9 via a group of reduction gears, and a pin 1 of the rotating plate 10.
It is composed of a drive link 11 connected to 0a and a drive arm 12 connected to the drive link 11, and the drive link 11 is connected to the first link 11
a and a second link 11b, the first link 1
The free end of 1a is rotatably supported by a pin 10a provided at the end of the rotary plate 10, and the second link 1
The free end of 1b is connected to a support plate 13 formed upright on the side of the machine stand 1 and a support shaft 14 provided on the support stand 3.
Further, the drive arm 1 is fixed to the support shaft 14.
The base end of 2 is fixed. In addition, the support shaft 1
As described above, the tape guide arm 5 is also rotatably supported on the drive arm 4, and the tips of the tape guide arm 5 and the drive arm 12 are connected.

With the above configuration, the binding tape 4 stretched between the tape holder 2 and the tip of the guide arm 5 is pushed into the object to be bound 8 from the front of the machine stand 1, and the binding tape 4 is pushed between the top surface of the machine stand 1 and the tape guide arm 5 and the tape receiver. It is placed in the space formed between the base 2 and the base 2. When the electric motor 9 is started by operating the starting switch 20, the rotary plate 10 rotates once, and the second link 11b of the drive link 11 swings left and right about the support shaft 14. Drive arm 1 fixed to 14
2 swings up and down to similarly swing the guide arm 5. When swinging downward, the tip of the guide arm 5 hits the tape holder 2, and the binding tape 4 guided by the tip touches the binding tape 4 held on the holder 2.
The bonded ends are cut by a cutting means (not shown), and the objects 8 to be bound are thereby bound. When the guide arm 5 is swung upward, the tape holder 2 holds the cut end of the binding tape 4, so the tape holder 2
A new binding tape 4 is placed between the guide arm 5 and the tip of the guide arm 5. The object to be bound 8 is taken out from the side.

Next, as shown in FIG. 1, the starting switch 20 for the electric motor 9 of the drive section is opened at the top, and
It is housed inside a substantially rectangular parallelepiped switch box 21 having a hanging piece 21b on one side of the lower surface 21a,
The switch button 22 is the switch box 21
A magnet 2 is provided on the lower surface 21a of the switch box 21, facing upward from the opening 21c.
3 is installed, while the switch box 2
1 and a binding machine drive unit including an electric motor 9 are connected by a connecting cord 26 through cord passage holes 24 and 25 formed in the switch box 21 and the machine base 1 of the binding machine A, respectively. ing. The connection cord 26 is provided sufficiently long.

As mentioned above, the magnet 23 is attached to the lower surface of the switch box 21, so when the magnet 23 is brought into contact with the surface of the machine base 1, the switch box 21 is fixed by its magnetic attraction force. The switch box 21 is located in the through hole 24 of the machine base 1.
Since the connecting cord 26 can be freely moved within the range of the length between the connecting cord 26 and the through hole 25 of the switch box 21, it can be moved to any position within this range as shown in FIG. 2 or 3. Can be fixed magnetically. In this way, the starting switch can always be provided at the most easily operated position depending on the conditions such as the size and shape of the objects 8 to be bound, so that the workability of the binding work is improved. Note that the extra cord may be accommodated on the lower surface side of the machine base 1 through the cord insertion hole 25.

Note that if the switch box 21 is moved closer to the center of the machine base 1 than necessary, the tape guide arm 5
may hit the switchbox 21 during the downward movement, interfering with the binding operation, or the switchbox 21 may be covered by the objects 8 to be bound, making it difficult to operate. However, the lower surface 22a of the switch box 21
Since a hanging piece 21b is formed protruding from one side of the machine, the installation of the switch box 21 is limited to corner positions around the machine base. Therefore, the switch box 21 does not impair the smoothness of the bundling work or switch operation.
