Description

Automatic binding device of packing the strings}

The present invention relates to an automatic binding device for wrapping strings, and more particularly, for packaging that is fed by maintaining a tension to wind agricultural products such as roses or green onions (hereinafter referred to as "packaging"). The present invention relates to a packaging automatic strapping device for rotating a string to bind a package to a predetermined bundle.

1 is a schematic side view of a packaging string automatic binding device according to the prior art.

As shown, the binding drive motor 1 allows the package to be bundled with the packing string 5, and the power from the driving motor 1 is transmitted to the arm 2 which binds the package at its own rotation. The tension transmission device 6 for adjusting the tension of the power transmission means 3, the packing string 5 which is drawn out from the packing string holder 4 and fed to the arm 2 side, and the arm 2 of the arm 2; Automatic bundling and cutting device (7) and a clutch of power transmission member (3), which are wound by winding the packing with the packing string (5) and then automatically cutting the packing string (5) due to rotation. And a solenoid 8 which is connected to the power transmission so as to control the transmission of the power from the drive motor 1 to the power transmission means 3 via the clutch.

Reference numeral 9 is a predetermined position where the limit switch 10 for turning on the power of the driving motor 1 by detecting the contact with the cutter not shown and cutting the package cut by the cutter at a predetermined length. It is a table mounted on.

Figure 2 is a schematic perspective view of a notch assembly that automatically wraps and wraps a package as a wrap strap in a prior art wrapping strap automatic binding device and then cuts it.

As shown, the knotter assembly 20 is equipped with gears 21a and 21b at both ends of the shaft 21 penetrating its body, and formed at right angles with respect to one gear 21a. The gear 22a meshing with the gear 21a is mounted at the lower end of the 22, and the rotor 23 is rotatably mounted at the upper end of the shaft 22 described above.

At this time, the above-described notch 23 is a movable piece (23a) formed in the shape of a bird's beak (spout) and a movable piece rotatably mounted with a pin formed on one side of the lower part of the fixed piece (23a) as a central axis ( It consists of 23b), and the roller 23c is fixedly supported on the extension part extended downward from the rear end of the movable piece 23b. The cam 24 which consists of the tapered circumferential surface 24a and the vertical surface 24b of an upper and lower light shape is formed in the lower part of the notch 23. As shown in FIG.

The upper surface of the above-described rotor assembly 20 is fixed to the rotor lever 26 of a predetermined shape by a fixing bolt 25 so as to be rotatable, with respect to one side (fixing bolt 25) of the rotor lever 26. As the end portion of the leaf spring 27 fixed to the front surface of the notch assembly 20 is supported on the right side portion slightly shifted to the right side, the notch lever 26 is elastically biased as an initial state to rotate in a counterclockwise direction.

For this reason, the above-mentioned notch lever 26 exerts an external force so that the roller 23c fixedly supported by the movable piece 23b of the notch 23 in contact with it may be in close contact with the vertical surface 24b of the cam 24. As it is formed so that the movable piece 23b is elastically in close contact with the fixed piece 23a.

When the bundle of flowers is bundled using the prior art packing string automatic binding device configured as described above, the ends of the flower stems are cut by a predetermined length using a cutter not shown, and then the table (9). The driving motor 1 is driven by contacting the limit switch 10 mounted at one side.

As a result, the power from the drive motor 1 is transmitted to the arm 2 through the clutch of the solenoid 8 and the power transmission means 3 which is mechanically actuated therewith and rotates it.

At this time, since the packing string 5 from the above-described packing string storage box 4 is fed to the arm 2 while the predetermined tension is maintained by the tension adjusting device 6, the packing string 5 is rotated. By using it, the package can be automatically wound up.

3 (a, b, c) is a view for explaining the process of forming the knot of the packing string by the drive of the notifier shown in FIG.

As shown in Fig. 3 (a), the roller 23c fixed to the movable piece 23b of the noter 23 described above moves by contacting the tapered circumferential surface 24a of the cam 24. In the state where the piece 23b is opened from the stationary piece 23a, that is, the rotor 23 is open, the wrapping string 5 is circumscribed to the outer periphery of the stationary piece 23a of the notch 23 and the movable piece 23b. Due to the rotation of the arm 2 is wound once outside the bundle of flowers, one side of the wrapping string (5) once wound (between the fixing piece 23a and the movable piece 23b) (that is, In the state where the wrapping string 5 is inserted into the inside of the notch 23 having a beak shape, the roller 23c is rotated by the cam 24 so that the rotor 23 is rotated due to the driving of the gears 21a and 22a. It is positioned on the vertical plane 24b of (see Fig. 3 (b)).

As shown in Fig. 3 (b), the elastic force acts from the lever lever 26 which is in contact with the above-described roller 23c at the position of the “a” shaped vertical portion 24b of the cam 24. Since the movable piece 23b of the notch 23 is in close contact with the stationary piece 23a, the packing string 5 located between the stationary piece 23a and the movable piece 23b is thus the notch 23. Keep the bite tight so as not to fall off.

As shown in Fig. 3 (c), the stripper 5, not shown, is operated while the packing string 5 is bitten by the notifier 23, so that the packing string 5 wound around the outside of the notifier 23 is moved forward of the front thereof. When the rotor assembly 20 is rotated backwards at the same time, the packing string 5 between the fixing piece 23a and the movable piece 23b of the rotor 23 is knotted forward. After the knot is formed, the binding of the package is completed by cutting the packing string 5 using a cutter not shown.

At this time, in the case where the packaging string automatic binding device is repeatedly used, abrasion occurs in the roller 23c fixed to the movable piece 23b of the above-described notch 23, so that the roller 23c is perpendicular to the cam 24. When placed in the part 24b, the elastic force from the notch lever 26 is not transmitted to the movable piece 23b accurately, so that the mouth of the notch 23 cannot be kept tight. As a result, the knots of the packing string 5 are poorly treated or impossible as the packing string 5 pinched between the movable piece 23b and the fixing piece 23a of the notch 23 is easily detached from them. Will have

On the other hand, the safety cover is not attached to the cutter which rotates at a predetermined speed and cuts the stem of the package at a predetermined length, and the cutter is continuously driven when the driving motor power of the cutter is not turned off during the operation. Since the risk is exposed, there is a risk that accidents that injure part of the body of the worker may occur when a safety accident occurs due to the carelessness of the worker.

Further, the power transmission means 3 which transfers power from the driving motor 1 to drive the arm 2 by contacting the package to the limit switch 10 mounted on the table 9 described above. The cost is increased due to the increase in the number of parts by the clutch and the solenoid 8 which is mechanically connected to the clutch, and it is frequently caused by their complicated structure so that they can be managed after-sales (A / S). There is a problem that the maintenance cost is increased.

Then, in the case of controlling the transmission of power to the power transmission means 3 by the solenoid 8 and the clutch described above, the package is wound as the packing string 5 when the power of the drive motor 1 is on. Irrespective of the noise, the noise generated by driving the member of the power transmission means 3 which rotates the arm 2 irrespective of the operation causes the problem of having to work in a poor working environment. .

On the other hand, the work process line for cutting the package by the cutter on the table 9 described above, and the work process line for binding the cut package as the packing string 5 due to the rotation of the arm 2 are located on the same straight line. Otherwise, the cutting work and the binding work of the package do not proceed continuously on the table 9, resulting in a problem that the workability is remarkably degraded.

Therefore, an object of the present invention is to wrap the packaging string to be fed with a controlled tension tension wrapping device automatic binding device to work in a comfortable environment by remarkably reducing the noise generated during the binding to the bundle To provide.

Another object of the present invention is to significantly reduce the cost cost by reducing the number of parts that transmit the power of the binding drive motor to the power transmission means only when the arm is driven, significantly reducing the maintenance cost of post-management due to the low failure rate It is to provide a packaging strap automatic binding device to be lowered.

Still another object of the present invention is to provide a work strap for cutting a package and a work strap for cutting a strap after binding the package on the same line so as to greatly improve workability due to continuous work. It is to provide an automatic binding device.

Still another object of the present invention is to eliminate the need to adjust the lever to compensate for the amount of wear of the rotor by replacing it when the wearer wraps the package with a packing string to form a knot. It is to provide a packaging strap automatic binding device to simplify the shape of the pin to improve its workability.

Therefore, the technical content of the present application is not limited.

As shown in FIGS. 4 and 7, the frame 11 on which the binding drive motor 1 is mounted, the cutter 12 cutting the package, and the package 12 detect the contact when the package is in contact with each other to drive the driving motor 1. The table 9 on which the standard position table 13 to which the limit switch 10 is attached is installed, and the package is driven by the power transmitted from the driving motor 1 when the package contacts the limit switch 10. Packed by a notch 23 made up of an arm 2 to hold the package with the packing string 5 to be fed and held, a movable piece 23b on which the roller 23c is mounted, and a fixing piece 23a. 5) to adjust the tension of the packing strap 5 so as to feed the arm 2 in a state in which the packing assembly 5 to bind the package to form a knot and the aforementioned packing string 5 maintains a predetermined tension. Tightening device (6) to make it possible, and bundle to bundle the package with the packing string (5) and then automatically bundle to cut It is applied to the strapping automatic binding apparatus having a cutting device 7 and the like.

At this time, the detailed description of the configuration and operation of the corresponding parts that are applied substantially the same as the conventional shown in Figures 1 and 3 will be omitted, and the overlapping reference numerals are indicated to be the same.

Therefore, according to a preferred embodiment of the present invention, the safety cover 14 is rotatably mounted to the above-described cutter 12 so as to protect the worker from the cutter 12 when cutting the package, and wrap the package The electronic clutch 15 which intercepts the power so that the power from the drive motor 1 is transmitted to the arm 2 only when it is bundled with (5) is connected to the drive motor 1 and mounted to the frame 11, The shape of the fixing pin 31 which supports the rotor lever 26 so as to be rotatably fixed so as to compensate for the amount of wear by replacing it when the notch 23 is wound around the packing string 5 to form a knot. Simplify to pin shape for machining.

The stepping switch 16 which drives the cutter 12 due to the pressurization of the user only when cutting the package is electrically connected to the drive motor 17 for the cutter, and the work of cutting the package and the package as the packing string 5 The cutter 12 is fixed to be positioned on the same line as the automatic bundle and the cutting tool 7 by the bracket 18 mounted on the frame 11 so that the operation of binding and cutting is continuously performed.

Reference numeral 19 is a control mounted to the above-described frame 11 and provided with a power switch for turning on / off the power of the drive motor 17 and the binding drive motor 1 for the package cutting machine, respectively. It's a box.

Hereinafter, a description will be given of a method of using a packaging string automatic binding device according to the present invention.

By operating the power switch of the above-described control box 19 to switch the power supply of the drive motor 17 for the cutter and the binding drive motor 1 to the on (on) state, the above-described drive motor 17 and The cutter 12 driven by the pressure of the stepping switch 16 electrically connected cuts the end of the flower stem such as a rose to a predetermined length. At this time, the safety cover 14 which is rotatably mounted to the cutter 12 may prevent damage to a part of an operator's body, especially a finger.

As the cut package comes into contact with the limit switch 10 of the standard position table 13 mounted on one side of the table 9, its detection signal is transmitted to the binding drive motor 1 mounted on the frame 11. It will drive it. Power from the driving motor 1 is transmitted to the arm 2 through the power transmission means 3 by the driving of the electromagnetic clutch 15 connected thereto to rotate it.

At this time, the above-described electronic clutch 15 is connected to transfer the power from the drive motor 1 to the power transmission means 3 only when the arm 2 for winding the package with the packaging string 5. Since the belt pulley is prevented from idling, noise generated during the work can be significantly reduced.

Accordingly, the arm 2 in a state in which the wrapping string 5 from the wrapping string holder 4 mounted on one side of the frame 11 maintains a predetermined tension by the aforementioned tension adjusting device 6. Since the feed is rotated to the outside of the package can be automatically wound around the package using the packaging strap (5).

Next, as shown in FIGS. 2 and 3, the movable piece 23b is far from the movable piece 23b due to the driving of the roller 23c with respect to the fixing piece 23a forming the notch 23 of the above-described rotor assembly 20. The wrapping string 5 is wound once outside the fixing piece 23a and the movable piece 23b in an easy state (a state in which the container 23 is open). One side of the wrapped strap 5 wound in this way is snapped between the stationary piece 23a and the movable piece 23b due to the rotation of the rotor 23, and then forms a knot. As the packing string 5 is cut by the cutter, the binding work of the package is completed.

When the roller 23c and the movable piece 23b of the notch 23 wear due to the repetitive driving of the above-described notch assembly 20, the notch 23 is incompletely driven to completely seal the package as the packing string 5. Can not be bound.

At this time, as the roller 23c and the movable piece 23b of the notifier 23 are replaced with new ones, the operation of adjusting the notch lever 26 to move horizontally toward the cam 24 becomes unnecessary. In addition, it is possible to simplify the shape of the fixing pin 31 for holding the notch lever 26 fixed, it is possible to greatly improve its workability.

On the other hand, the same straight line with respect to the automatic bundling and cutting device 7 which bundles the package | package with the packing string 5 and forms the knot by cutting the cutter 12 mounted on the table 9 so that the above-mentioned package material may be cut by predetermined length. By arranging on the frame 11 so as to be positioned as, it is possible to continuously perform the operation of binding the package after cutting the package can significantly improve the workability.

In addition, it is possible to mount the limit switch 40 for driving the drive motor 17 for the cutter when the package is in contact with the front side of the safety cover 14 described above.

As described above, the present invention is able to work in a comfortable environment by remarkably reducing the noise generated when binding a bundle by wrapping a predetermined package as a packing string to be fed with a controlled tension.

In addition, by reducing the number of parts that transfer the power of the binding drive motor to the power transmission member only when the arm is driven, the cost cost is drastically reduced, and since the failure rate is low, it is possible to significantly lower the maintenance cost after the maintenance.

The work process for cutting the package and the work process for cutting the packaging string after binding the package can be performed on the same line, thereby greatly improving workability due to the continuous work.

It is unnecessary to adjust the lever to compensate for the amount of wear of the notch as it replaces the notch that forms the knot by wrapping the package with the wrapping string, and the shape of the fixing pin for holding the notch lever is simplified. Workability can be improved.
