Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention provides first and second rotating shafts for supporting bag hanging, each having a threaded portion formed at one end thereof, by adjusting the lead angle of the threaded portion. A storage part is formed adjacent to the threaded part of the first and second rotating shafts to support the bag, and the storage part has an opening near the bag opening. With the grain storage bag inserted and supported through a pair of left and right eyelets formed at both ends in the width direction, and with the eyelets screwed into the threaded part, The first band plate for opening the bag is configured to be moved to a predetermined position below the grain discharge port set on the opposite side of the storage section by rotational driving at the grain storage bag, The base end portions of the second strip-shaped reinforcing members are integrated with the right eyelet, and the base ends of the second strip-shaped reinforcing members are extended from the base end of the first strip-shaped reinforcing member toward the bag opening side. Attach the ejected distal end to the peripheral edge forming the bag opening on the front side in the feeding direction, and at the same time, the distal end extends from the proximal end of the second strip reinforcing member toward the bag opening. is attached to the peripheral edge on the rear side in the feeding direction of the peripheral edge forming the bag opening; together with the eyelet, the first strip-shaped reinforcing member is attached to the first rotating shaft, and the second strip-shaped reinforcing member is attached to the peripheral edge of the peripheral edge forming the bag opening. each strip-shaped reinforcing member is set in a posture along the lead angle of the threaded portion at a predetermined position below the grain discharge port while being fitted onto the second rotating shaft;
The bag opening is switched to an open state by protruding the tip of the first strip-shaped reinforcing member toward the front in the feeding direction and the tip of the second strip-shaped reinforcing member toward the rear in the feeding direction. The present invention relates to an automatic bagging device for grains configured as follows.

[Conventional technology]

Conventionally, in this type of automatic grain bagging apparatus, the first and second rotating shafts were simultaneously operated to feed the bag to a predetermined position below the grain discharge port.

[Problem to be Solved by the Invention] However, when both rotating shafts begin to rotate and the eyelet engages with the threaded portion, and the grain storage bag is fed out and transferred, the threaded portion of the eyelet may be caught. Bags may not be transferred due to poor congestion. In particular, as shown by the two-dot chain line in FIG. 1, such a biting error occurred on one rotating shaft, more specifically, on the second rotating shaft 4B on which the second strip-shaped reinforcing member 6B described above was fitted. If this occurs, only the eyelet 2A fitted onto the first rotating shaft 4A will be transferred.

In this case, the bag opening 1 will be expanded beyond the intended opening area by the first strip-shaped reinforcing member 6A, and the grain storage bag 3 may be damaged or the preceding eyelet 2B may be damaged due to the threaded groove 14. I had a problem when it came off.

An object of the present invention is to provide a bag that can be smoothly fed out simply by changing the drive timing of the first and second rotating shafts.

[Means to solve the problem]

The characteristic configuration according to the present invention is to provide a control mechanism for driving and stopping the rotation shaft, and to provide a sensor for detecting that the left and right eyelets have reached a stop position at a predetermined position below the grain discharge port, respectively, and to control the rotation shaft. In configuring the mechanism, the second rotating shaft on which the second strip-shaped reinforcing member is fitted is first started to rotate, and the sensor detects that the second strip-shaped reinforcing member has reached a stop position. Based on the sensing operation of the sensor, the second rotating shaft is stopped, and the first rotating shaft on which the first band-shaped reinforcing member is fitted is started to rotate, and based on the sensing operation of the sensor, the second rotating shaft is stopped. The first rotating shaft is configured to stop, and its effects are as follows.

[Effect]

That is, the first rotating shaft is operated only after the second rotating shaft is first rotated and the eyelet attached to the rotating shaft reaches a predetermined position of the grain discharge port and stops. Therefore, since the first rotating shaft does not rotate in advance, it is possible to avoid forcibly expanding the bag opening beyond the limit with the first strip-shaped reinforcing member.

Moreover, due to the rotation of the second rotating shaft, only the second strip-shaped reinforcing member moves independently and becomes distant from the first strip-shaped reinforcing member, but this second strip-shaped reinforcing member acts in the direction of closing the bag opening, so the bag will not be expanded more than necessary until the grain reaches a predetermined position.

〔Effect of the invention〕

As a result, the starting timings of the first rotating shaft and the second rotating shaft are made different, and the second strip-shaped reinforcing member adjusts the starting timing of the first rotating shaft, which rotates with a delay, to a predetermined position below the grain discharge port. Since this is done after the opening, it is possible to effectively utilize the simple automatic opening mechanism between the first and second strip-shaped reinforcing members and the lead angle of the threaded portion, while suppressing troubles during bag transfer.

〔Example〕

Below the grain discharge port 5 of the hopper 8 in which grains are stored, first and second rotating shafts 4A and 4B for hanging and supporting a pair of left and right bags are installed. A grain storage bag 3 having hanging support eyelets 2A and 2B attached to both ends in the opening width direction near 1 is stored and supported,

The rotating shafts 4A and 4B are configured to have different protruding lengths (that is, the tip of the second rotating shaft 4B is located at the rear in the feeding direction compared to the tip of the first rotating shaft 4A), and the grain discharge port 5 The stop positions of the eyelets 2A and 2B of the bag 3 fed out to a predetermined position below are set so as to be forward and backward in the feeding direction. Therefore, the peripheral edge of the opening 1 of the bag 3 is inclined with respect to the feeding direction, and both the strip-shaped reinforcing members 6A and 6B can be brought close to a posture perpendicular to the peripheral edge. Band-shaped reinforcing members 6A, 6
The opening effect of B can be made more effective and the opening area can be increased.

In this way, after the grain filling operation is performed on the bag fed out to a predetermined position below the grain discharge port 5, the rotary shafts 4A and 4B are rotated again to take out this bag 3, and the next 3 The timing for feeding out the screws to a predetermined position is determined by operating the motors 17, 17 based on the sensing operation of the sensor 16 which detects that the slider 9 of the fastener 10 provided in the opening 1 is closed after grain filling. It is set as.

Limit switches 19, 19 are provided at the tips of the rotating shafts 4A, 4B as sensors to detect whether or not the bag 3 is fed out to a predetermined position, and the limit switch 19 senses contact with the eyelets 2A, 2B of the bag 3.
