Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention raises a bag filled with contents such as powder and granules along a main body frame by a driving member and allows the contents to pass through a hopper / shooter at a predetermined height position. The present invention relates to a bag overturning device for overturning to drop and discharge it to another device.

[0002]

2. Description of the Related Art As a bag rollover device of this type,
Various types have been proposed, but due to the structure, the roll angle can only be about 150 °, and it was difficult to roll the bag over 180 ° because it was difficult.

[0003]

Therefore, fine packing such as powder or granules, small lumps such as gravel, etc., which are sticky, or filling which is wet when mixed with water (hereinafter , These are referred to as the contents.) It is difficult to discharge all of them after they roll over and remain in the bag. In addition, if it is used continuously, the remaining contents may be dried and solidified and deposited, and the removal processing thereof becomes extremely difficult work.

Therefore, the present invention solves the above-mentioned conventional problems, and provides a bag overturning device capable of efficiently discharging almost the entire amount of contents without remaining in the overturning bag. The purpose is to do.

[0005]

In order to achieve the above-mentioned object, the invention of claim 1 is, in the bag overturning device as described above, a vibration motor provided in a bag, and the overturning of the bag by this vibration motor is almost completed. And a control member for controlling the driving so that the driving is started at a time point and the driving is stopped after a lapse of a predetermined time after the end of the rollover. According to a second aspect of the present invention, in the first aspect, the bag includes a bag main body provided with a vibration motor, and a tilting middle plate having one end pivotally supported and accommodated in the bag main body. At the end of the rollover, the roll is tilted more largely than the bag body. According to a third aspect of the present invention, in the first aspect, the main body frame is provided with a cushioning device for isolating the entire device during vibration of the bag by the vibration motor.

[0006]

As described above, since it is possible to apply vibration to the bag whose rolling is almost completed by the vibration motor, almost all of the content in the bag is efficiently discharged without remaining.

It is an expansion side view of the lower part of the device. Reference numeral 1 denotes an upright body frame, which has a pair of front and rear rectangular frames 2 and 3 each having a predetermined height. A box-shaped bag 5 having an upper opening is arranged in a space between the two frames 2 and 3 so as to be able to move up and down. The bag 5 is placed and fixed in a box-shaped support frame 6 having an open upper end and one side end, and the other end of the support frame 6 is attached to a mounting shaft 8 by a mounting portion 7. Wheels 9 are provided at both ends of the mounting shaft 8 and are vertically movable by engaging guide rails 10 and 11 which are erected on opposite surfaces of the frames 2 and 3.

An upward rollover arm 13 is attached to one end of the support frame 6, and both ends of an attachment shaft 14 are attached to the tip of the arm. Wheels 15 are provided at both ends of the mounting shaft 14 similarly to the mounting shaft 8, and engage with lateral guide rails 16 and 17 which are erected on the surfaces of the frames 2 and 3 facing each other so as to be movable up and down. Has become. Rollover guide rail 16,
Reference numeral 17 denotes a shape in which an upper portion from a lower end indicated by (a) to an upper end indicated by (b) is curved in an arc shape. Is guided by the overturn guide rails 16 and 17 to be turned over.

A chain attachment 21 is attached to both ends of the mounting shaft 8, and a lifting chain 22 is attached to the attachment. The chain 22 is a drive shaft rotatably mounted between the lower frame bodies 2 and 3 of the main body frame 1.
23 (see FIG. 4) Sprocket 24 and body frame 1
Driven shaft 25 rotatably mounted between frames 2 and 3 above
It is mounted between the upper sprocket 26 (see FIG. 3). Another sprocket 28 at the end of the drive shaft 23 (see FIG. 1)
A chain 31 is mounted between the sprocket and the sprocket 30 mounted on the shaft of the drive motor 29, and the drive shaft 23 is rotated by the drive of the motor 29 to move the chain 22 to the sprocket 24, The bag 5 connected to the chain 22 via the mounting shaft 8 or the like can be moved up and down by rotating the bag 26. The motor 29 is capable of forward and reverse rotation.

As shown in FIG. 5, the bag 5 comprises a bag body 5a mounted and fixed on a support frame 6 and a tilting middle plate 5b which is housed in the bag body with its upper end pivotally supported by a hinge 32. ing. Reference numeral 33 is a stopper that regulates the reference position of the tilting plate 5b before tilting, and 34 is a tip receiving member. The chain line position of the tilting plate 5b in FIG. 5 represents the maximum tilt position. In FIG. 1, reference numeral 35 is a shock absorber as a shock absorber that absorbs the impact of the bag 5 when it reaches the upper rollover end position. In FIG. 2, 36 is a vibration motor provided at the bottom of the bag 5, and 37 is a shock absorber as a shock absorber that absorbs the shock when the bag 5 descends and reaches the lower standby position.

The operation of the above embodiment will be described. The bag 5 at the lowermost standby position in FIG. 1 is filled with contents, and its weight is measured by a load cell (not shown),
When the weight reaches a predetermined value, a normal drive signal is output to the drive motor 29 from a control member (not shown). This allows the motor 29
Drives to rotate the drive shaft 23, and moves the bag 5 through the sprocket 24, the sprocket 26 of the driven shaft 25, the chain 22 and the wheels 9 of the mounting shaft 8 along the guide rails 10 and 11. To raise. Then, when the raised bag 5 passes the intermediate position in the height direction and the wheels 15 of the mounting shaft 14 come to the curved upper portions of the overturn guide rails 16 and 17, the bag 5
Starts to roll over, and the inclination gradually increases, and when it tilts to an angle almost close to reversal (150 ° in this example), it abuts on the shock absorber 35, and the driving of the motor 29 is stopped by this and the roll over is completed. . At this time, the tilting plate 5b of the bag 5 is tilted more largely than the bag body 5a and is inverted (18
Since it rolls over to near 0 °, the stored contents can be dropped and discharged smoothly.

At the same time when the bag 5 reaches the rollover completion position, a drive signal is output from the control member to the vibration motor 36, and the motor 36 is driven to vibrate the bag 5. This vibration continues until a predetermined time elapses after the bag 5 is overturned, and as the time elapses, a stop signal is output from the control member to the motor 36, and the vibration on the bag 5 ends. Due to the vibration during this period, almost all of the content in the bag 5 is dropped and discharged. Simultaneously with the stop of the motor 36, a reverse drive signal is output from the control member to the motor 29, which causes the bag 5
Is lowered and abuts on the shock absorber 37, whereby the driving of the motor 29 is stopped and the motor 29 is returned to the original standby position.

Although the specific construction of the control member is omitted in the drawing, it is made up of known electric parts. Further, in the above description, the vibration motor 36 is driven to vibrate the bag 5 at the same time when the rolling of the bag 5 is finished. However, it may be vibrated when the rolling of the bag 5 is half finished. May be almost the time when is completed.

[0014]

According to the first aspect of the present invention, since it has the above-mentioned structure, it is possible to efficiently discharge almost all of the contents without leaving the contents in the overturned bag.
Therefore, unlike the conventional case, the remaining contents are not dried and solidified and accumulated. The invention of claim 2 is
Further, the effect that the stored contents are dropped and discharged smoothly can be expected. The invention of claim 3 further has an excellent effect that it can be expected that vibration of the main body frame during vibration of the bag can be absorbed and softened.
