Flip fabric for large-capacity bag {DEVICE FOR TURN INSIDE OUT OF CLOTHES FOR USING A LARGE SIZE BAG}

The present invention relates to a device for inverting the inner and outer surfaces of the bag in the process of manufacturing a large bag, more specifically, a large-capacity bag that can easily perform the fabric reversal operation using only two workers using a mechanical device Dragon fabric is about flipping.

A bag is a bag or bag that is made of paper, paper, cloth, etc., which is long and large so that things can be put in it.

Since the bag has a variable shape, the bag can be placed regardless of the shape of the object. Therefore, it is used as a convenient tool for storing or transporting various objects in a bundle. On the other hand, the size of the bag is determined according to the type of object to be used or the purpose of use to maintain a suitable storage capacity.

In particular, a bag or the like primarily for packing an object in a container box is manufactured with a large capacity of about 4 to 5 meters in length on one side that is much larger than the size of a bag generally considered. Such a large-capacity bag is generally made of a synthetic resin material that can withstand the weight of the object. In addition, various special coating films are coated on the inner surface of the bag to prevent the inflow of external air, foreign substances or moisture, etc. to improve the storage property of the bag.

In order to produce a large-capacity coated bag as described above, first, a coating film is coated on one side of the fabric (原 緞) to be made into a bag, and then dried to a suitable size and cut (裁斷).

The cut fabric is fabricated into a bag with a top and bottom ruptured by sewing both sides of the longitudinal direction while the coating film is exposed to the outer surface.

In this way, the fabric in the half sewn (半 半) is turned over so that the coating film and the sewing line can enter the inner surface of the bag.

When the bottom of the fabric is sewn in this way, only the top of the fabric is opened.

However, in the prior art, in order to flip the semi-sewn fabric, there was a disadvantage in that much manpower and time are consumed. In other words, the turret's size was so large that four workers had to hold each corner of the turret and turn it over. This flipping operation is not only productive but also one of the workers avoiding the worker's fatigue is very high.

Accordingly, an object of the present invention is to provide a large-capacity fabric fabric flip that can easily flip the fabric with less work force when producing a large-capacity large-capacity bag.

The present invention for realizing the above object in the fabric reversing for inverting the large-capacity bag fabrics, the support frame constituting the skeleton of the device, and the hanger for mounting the fabric for the bag to be installed on the tip of the support frame to turn over Means, a first actuator provided at the rear end of the support frame to pull the fabric for the bag, a movable member mounted to the movable portion of the first actuator and movable, and a guide provided at both sides of the support frame to guide the movable member. Means, a fixing means for fixing one end of the bag fabric to be turned over and installed on both ends of the movable member to the movable member, and a control means for performing the operation of inverting the bag fabric by controlling the fixing means and the first actuator. It provides a large-capacity bag fabric flip including a.

According to the present invention, two workers are placed on the front of the device to turn both ends of the fabric for the upside down to be fixed to the movable member by a fixing means and then operate the first actuator to move the movable member and the fabric together with the movable member This is flipped over and pulled up. The hanger means allows the fabric to be inverted while maintaining the unfolded state in the bent portion where the fabric is inverted. The control means controls the fixing means and the first actuator in accordance with the movable position of the movable member to release the fixing means at an appropriate time point and return the movable member to its original position.

In the exemplary drawing, a pneumatic or hydraulic cylinder 31 suitable for linear reciprocating motion is employed, but the present invention is not limited thereto and may be replaced by an electric motor or various other conventional driving means.

The rod 32 of the cylinder 31 is designed with a stroke which can move approximately from the front end to the rear end of the support frame 10 and is operated by the first switching valve 33. In the illustrated embodiment, the solenoid valve 33 using the electromagnet is used as the switching valve, but is not limited thereto. Ports 34 for supplying pneumatic or hydraulic pressure are respectively provided near both ends of the cylinder 31, and the ports 34 are connected to the first solenoid valve 33 through the pneumatic or hydraulic line 35. The first solenoid valve 33 is connected to a pneumatic or hydraulic tank, not shown in the drawing, via a line 35. The first solenoid valve 33 is switched by the control means described later to selectively supply air or oil supplied from the hydraulic or pneumatic tank to any one of the two ports 34.

Movable member 40 is a part that pulls to invert the fabric, is installed on both ends of the support frame 10 in a direction orthogonal to the direction in which the cylinder 31 operates, the middle portion of the movable member 40 It is fixedly coupled to the end of the rod 32 of the cylinder 31. Thus, the movable members 40 move together along the linear reciprocating motion of the rod 32.

On the other hand, the movable member 40 is installed on the support frame 10 by the guide means 50. Guide means 50 is composed of a guide rod 51 provided on both sides of the support frame 10 and a sleeve 52 provided on both sides of the movable member 40 so as to slide along the guide rod 51.

Fixing means (60) is installed at both ends of the movable member (40), respectively, to fix one end of the fabric for the bag to be turned over to the movable member (40), as shown in FIG. The fabric of the bag is fabricated by the operation of the second actuator 61, the second switching valve 62 and the second actuator 61 for selectively operating the second actuator 61, the second actuator 61 provided at both ends of the movable member 40. It consists of a holder-shaped holder 63 for holding or releasing one end. In the illustrated embodiment, the second actuator 61 and the second switching valve 62 are cylinders operated by pneumatic or hydraulic pressure to collectively control together with the first actuator 30 and the first switching valve 33. And a solenoid valve, which are not limited thereto, as mentioned above, and may be replaced by an electric motor or other conventional driving means.

On the surface where the fixed end 64 and the movable end 65 face each other, a plurality of teeth 66 are formed to intersect with each other, so that the fabric caught between them can be firmly held in a zigzag.

On the other hand, the first sensor 71 and the first stopper 72 for stopping the operation of the first actuator 30 and returning to the original position are installed at one end of the support frame 10 and one end of the movable member 40, respectively. do. Further, the second sensor 73 and the second stopper 74 for reversing the operation of the second actuator 61 for operating the holder 63 of the fixing means 60 are respectively one end of the support frame 10. One end of the movable member 40 is installed.

The first sensor 71 and the second sensor 73 may be implemented by a limit switch or the like, and may be variously implemented through other conventional sensing means.

The first sensor 71 is fixedly installed at the point where the movable member 40 is to be moved by the driving of the first actuator 30, and the first stopper 72 moves the linear movement direction of the movable member 40. As a reference, it is installed at one end of the movable member 40 located in line with the first sensor 71. Therefore, when the movable member 40 moves by the drive of the first actuator 30 to reach a predetermined position, the first stopper 72 contacts and operates the first sensor 71. The first sensor 71 switches the first solenoid valve 33 to reverse the driving of the first actuator 30. The reversed first actuator 30 returns the movable member 30 to its original position.

The second sensor 73 is installed at a point to release the holder 63 of the fixing means 60. Since the release of the holder 63 should be made before the linear movement of the movable member 40 is switched, it is preferable that the holder 63 is located slightly ahead of the installation position of the first sensor 71.

The second stopper 74 is installed at one end of the movable member 40 in line with the second sensor 73 based on the linear movement direction of the movable member 40. In the exemplary drawing, the second sensor 73 is installed at one edge of the support frame 10, that is, around the guide rod 51, and the second stopper 74 is at one edge of the movable member 40, that is, the fixing means ( 60) is installed around.

Therefore, when the movable member 40 starts from the initial position, the holder 63 is closed by the driving of the second actuator 61, and then the second stopper 74 contacts the second sensor 73. The instant holder 63 is opened.

On the other hand, as shown in Figure 6, the shock absorbing means 80 is provided as an auxiliary means behind the point where the linear movement of the movable member 40 is switched.

The movable member 40 tries to continue to move by its own inertia even when the driving force of the first actuator 30 is cut off by the first sensor 71 and the first stopper 72 at the maximum stroke. The shock absorbing means 80 absorbs the inertia force such that the movable member 40 can be quickly returned to its original position.

In the exemplary drawing, the shock absorbing means 80 includes two shock absorbing rods 82 and 83 to which the elastic force of the spring 81 acts. One of the shock absorbing rods is one of which the elastic force of the spring 81 is hard. The other is soft.

The driving stop signal is provided to the controller 75 to stop the driving. It is preferable that the operation switch 76 uses a foot switch or the like for the convenience of the operator.

The second solenoid valve 62 operates to hold the semi-sewn packaging fabric by driving the second actuator 61 under the control of the control unit 75 and the first solenoid valve 33. Under the control of the control unit 75 drives the first actuator 30 performs a function of sliding the movable member 40 in order to pull the original fabric caught by the fixing means (60).

The second sensor 73, which can be implemented as a limit switch, is disposed at the second position of the support frame 10, that is, the position at which the original fabric held by the second solenoid valve 62 is released, and is disposed by the first solenoid valve. When the position of the movable member 40 to be pulled reaches the second position, the detected signal is provided to the controller 75.

The first sensor 71 which can be implemented by another limit switch or the like is disposed at the first position of the support frame 10, that is, the position at which the original fabric pulled by the first actuator 30 is returned to the reverse direction. It detects when the solenoid valve 33 reaches the first position and provides the detected signal to the control unit 75.

The control unit 75 may be implemented as a microcomputer, and performs catching and dragging operations of the second and first solenoid valves 62 and 33 in response to a driving start signal generated by the operation of the operation switch 76. Control signals are provided to the second and first solenoid valves 62 and 33, respectively.

In addition, the controller 75 switches the second solenoid valve 62 according to a detection signal from the second sensor 73 that detects that the movable member 40 has reached the second position. A control signal for releasing the holding operation is generated, and the first solenoid valve 33 is switched according to a detection signal from the first sensor 71 that detects that the movable member 40 has reached the first position. A control signal is generated to perform the operation of repositioning 40 in the opposite direction.

The control operation of the fabric flip according to the present invention having the above-described configuration will be described in detail as follows with reference to the flowchart of FIG. 9.

First, in step (1), if the control unit 75 determines that the operation switch 76 of the far-end flip according to the present invention has been driven, the flow proceeds to step (2) to supply an appropriate current to the second solenoid valve 62. By providing an electromagnet, the movable end 65 of the fixing means 60 is brought into close contact with the fixed end 64 by the driving of the second solenoid valve 62, thereby carrying out a holding operation of the bag fabric encased therebetween.

In the next step 3, the control unit 75 drives the first actuator 30 to attract the movable member 40 by driving the first solenoid valve 33 as in step 2. Then, the cylindrical fabric caught by the fixing means 60 together with the movable member 40 is pulled together.

Thereafter, the controller 75 receives the detection signal from the second sensor 73 that detects when the movable member 40 reaches the second position set on the support frame 10 (step 4). 2 The solenoid valve 62 is switched to release the grip of the far end (step 5).

In the next step 6, when the control unit 75 receives the detection signal of the first sensor 71 which detects that the movable member 40 has reached the first position, as in (step 4), The first solenoid valve 33 is switched from the first position detected in step 7) to drive the movable member 40 in the original position.

Hereinafter, the operation of the large-capacity fabric fabric flip in accordance with the present invention will be described with the actual fabric flip operation.

The operator places dozens of pieces of fabric in a cylindrical state to be flipped on the fabric support frame 90 before entering the fabric flipping operation.

The worker is placed in front of the hanger means 20 in a pair of people, and pulls a piece of the fabric placed on the fabric support frame 90. The front end portion of the fabric is inserted between the fixed end 64 and the movable end 65 of the fixing means 60 by turning outward while surrounding the hanger means 20 by two workers. One of the workers then presses the actuation switch 76 by foot.

As described above, when the operation switch 76 is driven, the original fabric inserted into the fixing means 60 is firmly bited by the holder 63. Subsequently, the movable member 40 is operated by driving the first actuator 30 with a slight time difference from the holding operation of the fixing means 60.

Movable member 40 is led to the front end of the fabric caught in the fixing means 60 is linearly moved so that the fabric is pulled upside down relative to the hanger means (20). At this time, a plurality of bearings 22 installed in the semicircle to minimize the friction force in the bent portion of the fabric overturns.

When the movable member 40 reaches the second position, the original fabric remains in an inverted state, and the second sensor 73 is operated to release the fixing means 60 holding the original fabric and thus no longer move the movable member ( 40) is not attracted.

After a while, when the movable member 40 reaches the first position, the first sensor 71 is operated to move the movable member 40 to its original position. At this time, since the fixing means 60 is already released, only the movable member 40 remains intact while maintaining the inverted state. The two workers who confirmed this pull the fabric and pull it out of the fabric flip to complete the fabric flip operation.

In the above description, it should be understood that those skilled in the art can make modifications and changes to the present invention without changing the gist of the present invention as merely illustrative of a preferred embodiment of the present invention.

As described above, according to the present invention, it is possible to perform the fabric flip operation with only two people compared to the conventional method that required four people can obtain the effect of reducing the workforce. In addition, while the conventional work intensity was high, according to the present invention, since most of the work is performed through the fabric flip device can be obtained the effect of lowering the fatigue of the worker.
