Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically packing a packaging bag filled with tea leaves processed for tea production.

[0002]

BACKGROUND OF THE INVENTION To pack tea leaves that have been processed for rough tea,
Tea leaves, for example, 30k in a packaging bag S 'called "Omi"
g is filled in a prescribed amount, and the upper opening is first folded and sealed with an adhesive tape T 'or the like. Then, using a single binding machine J as shown in FIG. 9A, the packaging bag S 'is turned over by hand and bound by several binding bands B' made of polypropylene or the like, and packed. It is carried out. Specifically, in the binding operation, in a state where the packaging bag S 'is set up, first, one vertical binding is performed along the body length direction so as to pass through substantially the center of the upper and lower end surfaces S1' of the packaging bag S '. Next, the user holds the packaging bag S 'and rotates it so that the vertically wound binding position is changed, so that the binding band B' intersects at the upper and lower end surfaces S1 'in a radial manner such as a cross or a U-shape. One or several pieces are bound vertically. Then, the packaging bag S 'is held in hand and turned over, and the horizontal binding is performed in a so-called bale-tight manner in the circumferential direction of the trunk side portion S2'. In this horizontal binding, several pieces are bound in the trunk length direction while holding the packaging bag S 'in hand and shifting it sideways.

[0003] As a packing mode, as shown in FIG. 9 (a), a vertical binding that passes through substantially the center of the upper and lower end surfaces of the packaging bag S 'is formed into a two-piece cross, or a cross binding as shown in FIG. 9 (b). There are four units of U.S. unity. The horizontal binding performed in the circumferential direction of the trunk side portion S2 'is not only three, but also two binding as shown in FIG. 9C. As such a packing mode, an appropriate one is selected depending on, for example, the bulk of the filled tea leaves, that is, the size of the packaging bag S ′.

A packaging bag S 'filled with tea leaves as described above.
There were the following problems in the packing operation of the above. For example, the above-mentioned packing work requires about two workers,
We want to make this packing work unattended and automatic in order to save labor in the tea factory. Also, the work of holding the heavy packaging bag S 'in hand and turning it over is heavy labor,
The burden on the waist is also large. In addition, a certain amount of experience is required for packing well, and when packing is performed poorly, the binding band B 'may come off.

[0005]

[Technical Problems Attempted to Be Developed] The present invention has been made in view of such a background, and the operation of packing a tea bag-filled packaging bag, which has conventionally required relatively heavy labor and requires experience, has been carried out automatically. An attempt was made to develop an automatic packing method to be carried out in Japan.

[0006]

That is, in the automatic packing method according to the first aspect, a binding band is wound around a packaging bag having a substantially cylindrical shape filled with tea leaves in a body length direction. A vertical winding bundling step, and a horizontal winding bundling step of bundling a bundling band in the circumferential direction of the body with respect to the packaging bag to perform bundling, wherein the vertical winding bundling step,
All the packaging bags between the horizontal winding and bundling process are characterized by automatic unmanned transfer and automatic unmanned posture setting. ADVANTAGE OF THE INVENTION According to this invention, unmanned packing of a packaging bag can be performed, labor saving in a tea factory, or elimination of labor shortage can be performed. In addition, it is necessary for a worker to pack a bag while turning it upside down using a binding machine, which requires some experience.For example, if the packing is done poorly, the band may come off immediately. However, according to the present invention, such a problem is eliminated. The packaging bag is 30kg
Since it has a moderate weight, it takes a certain amount of power to pack it while holding it upside down and turning it upside down,
The burden on the waist and the like is large, but according to the present invention, such heavy labor is relieved.

The automatic packing method according to claim 2 is characterized in that, in addition to the above requirements, the vertical winding bundling step is performed first, followed by the horizontal winding bundling step. . According to the present invention, since the vertical banding is performed first, and then the horizontal banding is performed, the banding band of the vertical banding which is rather easy to be detached is not detached because the banding band for the horizontal banding is fastened. .

Further, in the automatic packing method according to a third aspect, in addition to the above requirements, the vertical winding is performed by a vertical winding machine,
The horizontal binding is performed by another independent horizontal binding machine. According to the invention,
Vertical binding and horizontal binding are performed in a streamlined manner, so that packing efficiency is improved, work speed is improved, and since the device does not have a complicated structure, manufacturing costs are relatively low. Is also possible.

The attitude changing conveyor 20 will be described.
The attitude changing conveyor 20 has a first half belt conveyor 21 and a second half belt conveyor 22, which can be inclined in a V-shape as viewed from the side as shown in FIG. 3 by air cylinders 21A and 22A as an example. . Of course, as a driving device for performing this inclination, the air cylinders 21A and 22A are used.
In addition to A, various devices capable of lifting one side of the first half belt conveyor 21 and the second half belt conveyor 22 other than the motor cylinder can be applied.

The vertical binding machine 10 is provided with a position detecting sensor 18 for detecting that the packaging bag S has reached the vertical binding machine 10 as an example. Position detection sensor 18
As an example, a photoelectric tube switch including a light emitter and a light receiver is used. In addition, various sensors such as an infrared sensor, an ultrasonic sensor, and a lever switch of a contact sensor can be used. When the position detection sensor 18 detects that the packaging bag S has reached the vertical winding and binding machine 10, the driving of the attitude changing conveyor 20 is stopped, and the first half belt conveyor 21 and the second half belt conveyor 22 are driven by the air cylinders 21A and 22A. Is lifted so as to form a V shape when viewed from the side, and binding by the vertical binding machine 10 is started.

Next, the horizontal binding line 3 will be described.

As a feature of the present embodiment, a front transfer conveyor 35 of the horizontal binding line 3 and a rear transfer conveyor 16 of the vertical binding line 2 are connected at substantially right angles. The arrangement in which the connection between the wire and the horizontal winding binding line 3 is substantially at a right angle is referred to as vertical and horizontal binding attitude converting means H in the present embodiment. This vertical and horizontal binding posture converting means H
Thus, the posture of the packaging bag S is changed, and switching between vertical winding and horizontal winding is performed.

The horizontal tying machine 30 has substantially the same structure as the vertical tying machine 10, and includes a main body 31, an arch guide 3 and the like.
2. It comprises a band wheel 33 and the like. The band setting press 14 provided in the vertical binding machine 10 is not provided because the horizontal binding machine 30 binds the body side portion S2 of the packaging bag S in the circumferential direction. A position detection sensor 38 is also provided around the horizontal binding machine 30 similarly to the vertical binding machine 10, and detects that the packaging bag S has reached the horizontal binding machine 30. In this embodiment, since the horizontal winding is performed at three positions, the position detection sensor 38 is also provided with first, second, and third position detection sensors 38A, 38B, and 38C. Incidentally, the first position detection sensor 38A starts the binding of the vertical binding unit 10 by the detection signal of the packaging bag S, and the second and third position detection sensors 38B and 38C respond to the vertical detection by the non-detection signal of the packaging bag S. The binding of the winding and binding machine 10 is started.

The member indicated by reference numeral C is a control device, which is connected to the devices of the vertical binding line 2 and the horizontal binding line 3 and the position detection sensors 18 and 38.

An example of the specific structure of the automatic packing apparatus 1 is as described above, and this operation mode will be described below. (1) Feeding to the vertical winding binding line First, before describing the operation mode of the automatic packing device 1, the manner in which the packaging bag S is fed to the vertical winding binding line 2 will be described. The fine adjustment of the filled tea leaves is performed while the weighing is performed by the weighing machine 4, and the packaging bag S in which the specified filling weight value is exactly the same,
The sheet is fed to the roller conveyor 5 by the first feeding device 6. In the roller conveyor 5, the upper side of the packaging bag S is bent by an operator and fastened with an adhesive tape T. The packaging bag S on which such a sealing operation has been performed is placed on the transfer table 7 by an operator in a state of lying down. The packaging bag S on the transfer table 7 is pushed out by the second feeding device 8 toward the vertical winding and binding line 2. On the transfer table 7 just before the vertical binding line,
The packing bag S is shifted upward in FIG. 2 by the shifting device 9 and sent onto the front transfer conveyor 15 of the vertical winding and binding line 2.

(2) Transfer to the vertical binding unit The packaging bag S is transferred to the front transfer conveyor 15 and then to the connected posture changing conveyor 20. The position detection sensor 18 detects the packaging bag S that is going to pass through the arch guide 12, and the driving of the attitude changing conveyor 20 is stopped. The position of the packaging bag S at this time is in the center of the posture changing conveyor 20, that is, between the first half belt conveyor 21 and the second half belt conveyor 22, and the center of the packaging bag S is surrounded by the arch guide 12 of the vertical binding machine 10. Is located on the surface to be

(3) First Vertical Wrap When the driving of the posture changing conveyor 20 is stopped, one end of each of the first half belt conveyor 21 and the second half belt conveyor 22 is lifted upward by the air cylinders 21A and 22A, and viewed from the side. V-shape. The binding may be performed while the posture changing conveyor 20 is flat. However, the V-shape allows the packaging bag S to be clamped, so that the stability at the time of binding is good.
Further, the band setting press 14 is extended and pushes the end face S1 of the packaging bag S toward the main body 11 side. Then, the binding by the vertical winding binding machine 10 is started. The binding band B is guided by the arch guide 12, is wound around the packaging bag S, is tightened by the main body, and the overlapping portion of the binding band B is thermally welded and cut to complete the binding. In addition, packaging bag S
When winding the binding band B, the band setting press 14
The binding band B is inserted from the rear side of the guide groove 14a and guided and wound forward, so that the end surface S of the packaging bag S is
The binding band B is wound at one center. Therefore, the binding band B that has been longitudinally bound is less likely to come off.

(4) Posture change by means of vertical winding binding position changing means-second vertical winding binding When one binding band B is bound, the packaging bag S is then moved to 90
Rotate to bind another binding band B. This is for performing so-called cross binding. The first and second belt conveyors 21 and 22 of the attitude changing conveyor 20 are driven. When the packaging bag S is rotated by 90 °, the driving of the first and second belt conveyors 21 and 22 is stopped. The drive may be stopped by detecting the number of rotations of the drive roller or the like with a sensor, or may be stopped by measuring the time with a timer. Then, the second binding band B is bound. It is to be noted that a so-called FIG.
In the case of performing U.S. character binding as shown in FIG.
The operation of changing the rotating posture and the operation of binding by the binding band B are repeated twice. When the vertical winding is completed, the first and second belt conveyors 21 and 22 are driven again with the belt conveyors 21 and 22 returned flat, and the packaging bag S is sent to the rear transport conveyor 16 and moved to the horizontal winding binding line 3. As described above, the vertical winding binding position changing means in the vertical winding binding line 2 is composed of the tiltable front half belt conveyor 21 and the rear half belt conveyor 22, and thus plays two roles of transport and posture change, and is simple and wasteful. And can be implemented inexpensively.

(5) Vertical and horizontal binding posture conversion The packaging bag S transported from the rear transport conveyor 16 is transferred onto the front transport conveyor 35 of the horizontal winding binding line 3. At this time, a posture direction conversion for switching from the vertical winding binding to the horizontal winding binding is performed. That is, in the vertical winding binding line 2, the body side portion S2 of the packaging bag S is opposed to the traveling direction, but since the vertical winding binding line 2 and the horizontal winding binding line 3 are connected at substantially right angles, the horizontal winding In the binding line 3, the posture is changed so that the upper surface or the surface of the packaging bag S is opposed to the traveling direction. Since the front transfer conveyor 35 is inclined toward the main body 31, the packaging bag S also moves toward the main body 31, and is transferred while the body side S <b> 2 is supported by the roller guide 37.

(6) Horizontal binding The packaging bag S transported by the forward conveyor 35 of the horizontal binding line 3 is first detected by the first position detection sensor 38A when the packaging bag S is going to pass through the horizontal binding machine 30. A signal is transmitted and the drive of the front and rear transfer conveyors 35, 36 is stopped. At this time, about a quarter from the front of the packaging bag S is located on the surface surrounded by the arch guide 32 of the horizontal binding device 30. Then, the first horizontal binding is performed. When the first horizontal binding is completed, the front and rear transfer conveyors 35 and 36 are driven again. Next, the second position detection sensor 38
When the non-detection signal of the packaging bag S of B is transmitted, the driving of the front and rear transfer conveyors 35 and 36 is stopped again. At this time, about two-quarters from the front of the packaging bag S is located on the surface surrounded by the arch guide 32 of the horizontal binding device 30. Then, the second horizontal binding is performed. When the second horizontal binding is completed, the front and rear transfer conveyors 35 and 36 are driven again. Next, when the non-detection signal of the packaging bag S of the third position detection sensor 38C is transmitted, the front and rear transport conveyors 3 are again activated.
The driving of 5, 36 is stopped, and the third horizontal binding is performed. When the three horizontal windings are bound, the rear transfer conveyor 36 is transferred as it is, and is appropriately loaded on a truck bed or stocked on the floor. As described above, since the vertical winding binding line 2 and the horizontal winding binding line 3 are provided with the position detection sensors 18 and 38 for detecting the position of the packaging bag S,
It is assisted to bind the binding band B exactly at a predetermined position.

[Second Embodiment] Next, a second embodiment using a horizontal direction conversion table 40 as the vertical / horizontal binding posture converting means H will be described with reference to FIG. That is, the horizontal direction conversion table 40 is provided between the vertical binding line 2 and the horizontal binding line 3. The vertical winding binding line 2 and the horizontal winding binding line 3 are connected in series, so that the horizontal direction conversion table 40 is set to rotate at an angle of 90 °. When the horizontal direction conversion table 40 is used as the vertical and horizontal binding posture converting means H, the connection angle between the vertical winding binding line 2 and the horizontal winding binding line 3 can be set at various angles. That is, as shown in FIG. 4B, the arrangement can be changed according to the convenience of the installation location, for example, at 45 ° when viewed from above. The basic structure of the vertical winding binding line 2 and the horizontal winding binding line 3 other than the horizontal direction conversion table 40 is the same as that of the second embodiment.

An example of a specific structure of the horizontal direction conversion table 40 will be schematically described. The horizontal direction conversion table 40 is a device that is rotatable at a fixed angle and can transfer the packaging bag S in the cross direction. That is, as shown in FIG. 5, the horizontal direction conversion table 40 is provided with a roller-type receiving conveyor 41 provided in a fixed state on a rotatable rotary table 40A.
1a is driven by a chain or the like. And, between the rollers 41a of the receiving conveyor 41, there is provided a sending conveyor 42 of a belt conveyor whose transport direction is orthogonal, and these sending conveyors 42 are provided with rollers 41a of the receiving conveyor 41.
It is possible to move up and down between a.

As described above, the vertical / horizontal binding posture converting means H is constituted, and in using the same, first, the packaging bag S is transferred from the rear transfer conveyor 16 of the vertical winding binding line 2 to the receiving conveyor 41 of the horizontal direction conversion table 40. Be transported. At the time of receiving the packaging bag S, the sending conveyor 42 is in a lowered state. Next, the turntable 40A rotates 90 °. Then, the delivery conveyor 42 is lifted upward to support the packaging bags S, and then the delivery conveyor 42 is driven so that the packaging bags S placed on the upper side are moved forward of the horizontal binding line 3 by the forward conveyor 3.
Send out to 5.

The horizontal direction conversion table 40 is provided with only a delivery conveyor 43 such as a belt conveyor as shown in FIG.
May be received by the payout device 44. The member indicated by reference numeral 45 is a stopper plate, which stops the rolling of the packaging bag S at a fixed position.

[Embodiment 3] Embodiment 3 shown in FIG. 7 shows an embodiment in which the vertical wrapping is performed with the packaging bag S standing. That is, the vertical winding binding line 2
When placing the packaging bag S on the front transfer conveyor 15 of the above, the packaging bag S is placed in an upright state. In place of the vertical binding machine 10, a horizontal direction conversion table 46 as described in the second embodiment is used in place of the attitude changing conveyor 20, and the attitude change for the cross binding and the U-shaped binding is performed. Will be Note that the posture change from the vertical winding binding to the horizontal winding binding is performed, for example, by providing a step and performing tilting guide at the time of transfer from the rear transfer conveyor 16 of the vertical winding binding line 2 to the front transfer conveyor 35 of the horizontal winding binding line 3. .

Fourth Embodiment A fourth embodiment shown in FIG. 8 shows an embodiment in which the vertical winding and the horizontal winding are performed without changing the posture. Specifically, the vertical binding line 2 performs the vertical binding in a state where the packaging bag S is upright, as in the third embodiment.

Or labor shortage can be eliminated.
Also, it is necessary for the worker to pack the bag S while turning it upside down using the binding machine, which requires some experience. For example, in the case of poor packing, the band is likely to come off immediately. In some cases, according to the present invention, such a problem is eliminated. In addition, since the packaging bag S has a weight of about 30 kg, a suitable force is required to appropriately hold the packaging bag in a hand and the burden on the waist is large. You are released from hard work.

According to the automatic packing method of the present invention, since the vertical banding is performed first and the horizontal banding is performed thereafter, the banding band B of the vertical banding which is rather easily detached is horizontally banded. And is not detached by the binding band B.

Further, according to the automatic packing method of the third aspect, the vertical binding is performed by the vertical binding machine 10 and the horizontal binding is performed by another independent horizontal binding machine 30. The vertical winding and the horizontal winding are performed at the same time, so that the packing efficiency is excellent and the working speed is improved.
