Abstract

PURPOSE: To enhance the mounting rate and speed of a main bag by extending the leading end part on the side of the opening part of the uppermost main bag of the stacked main bags of a holding arm to suck the main bag by the suction element provided to the leading end part and revolving the holding arm so as to make the sucked main bag vertical. CONSTITUTION: When an operation button is pushed, the pneumatic actuator of a holding arm 1 is extended and the uppermost main bag 11 on a main bag placing stand 3 is sucked by the suction element 4a provided to the leading end part of the actuator 5. Next, the actuator 5 is contracted to raise the main bag 11 from the main bag placing stand 3 and the holding arm 1 sucking the main bag 11 is revolved by 90 deg. to bring the main bag 11 to a vertical state. In this state, a moving arm 6 is moved along a guide rail 7 and the main bag 11 held to a vertical state is sucked by the suction element 4b provided to the leading end of the moving arm 6 on the side opposite to the holding arm 1 and the moving arm 6 is allowed to retreat to open the main bag and the opened main bag 11 is grasped by pneumatic chucks 9a, 9b.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a large sea bag attaching device for tea making, which automatically puts tea into the large sea bag and automatically attaches the large sea bag to a measuring device.

[0002]

2. Description of the Related Art As a conventional technique, Japanese Patent Application Laid-Open No. 1-1938
There is 46. This is a method in which the mounting portion of the large sea bag is a cylindrical holder, and the large sea bag is automatically opened into a substantially circular shape and inserted.

[0003]

In the conventional technology,
Since the method of inserting and mounting in a cylindrical holder is used, the bag is opened in a cylindrical shape and inserted into the holder.If the upper end of the bag is bent, it will not fit in the holder and it cannot be mounted. Fail. The large sea bag has a triple-layer structure in which a nylon bag is sandwiched between two strong paper bags, and it is stiff and extremely difficult to handle. for that reason,
When opening the bag in a circular shape, the upper end inevitably bent, and there was a failure in mounting.

Further, since the bag is opened in a circular shape, there is a problem that it takes time and the like, which affects the efficiency. In addition, when the type of the large sea bag is changed (the size is changed), the holder also has to be replaced, which causes a problem that the replacement work is troublesome and troublesome. The present invention was invented for the purpose of solving the above-mentioned problems.

[0005]

SUMMARY OF THE INVENTION An automatic mounting apparatus for a large sea bag for tea making according to the present invention has a holding arm rotatably mounted on a rod, and the holding arm is extendable and retractable, and a plurality of suction members are attached to the tip of the holding arm. A movable arm provided with a child and provided with a plurality of adsorbents at the tip opposite to the holding arm is movable left and right, and the above-mentioned holding arm is expanded and contracted, and the adsorbent at the tip makes a large sea bag. The upper arm of the bag is sucked and the holding arm is swung until the large bag is vertical, the moving arm is moved, the large bag is held by the adsorber, and the moving arm is moved horizontally to move the large bag. Characterized by opening the bag, lowering the elevating arm with two arms equipped with a chuck on the top of the bag that can be moved up and down, inserting the chuck into the end of the opened large sea bag, and holding it Automatic device for mounting large sea bags for tea making.

[0006]

According to the automatic large bag forming apparatus for tea making according to the present invention, the holding arm is extended to the tip end of the uppermost large sea bag stacked on the large sea bag placing table with the holding arm extended, and the suction is provided at the tip. The holding arm is swung 90 ° so that the sucked large sea bag is in a vertical state. On the other hand, the moving arm moves in a horizontal direction from a predetermined position, and the adsorbent provided at the tip of the moving arm adsorbs the opposite side of the holding arm and holds the large sea bag.

After gripping, the movable arm is quickly moved in the bag opening direction by a predetermined distance to open the large sea bag in a rectangular shape. After the bag opening is completed, the elevating arm having two arms descends, the chuck provided at the tip thereof is inserted into the open end of the large sea bag, the large sea bag is clamped, and the mounting is completed. After that, when the bagging is completed, the next large sea bag is automatically adsorbed, and the cycle in which the large sea bag is held by the chuck is repeated.

[0008]

An embodiment of the present invention will be described with reference to the drawings.
In the figure, reference numeral 1 denotes a holding arm, which has an L-shape, one end of which is rotatably attached to an upper end of a fixed column 2 which is erected in the vicinity of the large sea bag mounting table 3 and the other end of which is telescopic. It is free, and two adsorption elements 4a are attached to its tip. A method of turning the holding arm 2 is not particularly shown, but is driven by a pneumatic actuator. Alternatively, a deceleration motor may be used. Expansion and contraction of the holding arm 1 is performed by a pneumatic actuator.

Reference numeral 6 denotes an L-shaped moving arm, which is movable in the left-right direction along a guide rail 7 attached to the bagging machine main body side. The moving arm 6 is driven by a deceleration motor by driving a chain via a sprocket. Two adsorbents 4b are attached to the tip of the moving arm 6 and have the same structure as the adsorbent 4a. A suction hose (not shown) is connected to the adsorption elements 4a and 4b from a vacuum pump (not shown).
Can be adsorbed. Reference numeral 8 denotes an elevating arm having two arms, which is attached to the main body of the bagging machine and has pneumatic chucks 9a and 9b at its tip.

A motor is used for lifting and lowering, and the lifting and lowering is possible via a screw. Since this embodiment is configured as described above, its operation will be described in the order of operations. By pressing the first operating button, the pneumatic actuator 5 of the holding arm 1 extends the large sea bag 11 at the top of the large sea bag mounting table 3 and the adsorber 4a at the tip end is extended.
Causes the adsorber and then the pneumatic actuator 5 to shrink,
The large sea bag 11 is pulled up from the large sea bag placing table 3. In this case, the fixed column 2 is arranged at a position where the adsorbent 4a holds the tip of the large sea bag 11 on the opening side.

The holding arm 1 to which the large sea bag 11 is sucked is turned by 90 ° to bring the large sea bag 11 into a vertical state. On the other hand, the movable arm 6 moves from a predetermined position along the guide rail 7, and the opposite side of the holding arm 1 side of the large sea bag 11 in the vertical state is attached to the large sea bag 11 by the adsorber 4b at the tip of the moving arm 6. Hold. Then, the moving arm 6 quickly moves along the guide rail 7 by a predetermined distance in the direction to open the large sea bag 11,
Open bag 1. After opening the bag, the elevating arm 8 descends, and the opened large sea bag 11 is inserted between the pneumatic chucks 9a and 9b attached to the tip of the elevating arm 8. Insertion confirmation switch (not shown) provided on the pneumatic chucks 9a and 9b
When the insertion is confirmed, the pneumatic chucks 9a and 9b are closed, and when the mounting is completed, the holding arm 1 and the moving arm return to their original predetermined positions to prepare for the next mounting operation.

The distance between the centers of the pneumatic chucks 9a, 9b attached to the tips of the two arms of the lifting arm 8 is set in accordance with a predetermined bag opening distance of the large sea bag 11. After that, when the bagging of tea is completed, the next large sea bag 11 will automatically move to the pneumatic chuck 9 without pressing the operation button.
The cycles of attaching to a and 9b are repeatedly executed.

[0013]

EFFECTS OF THE INVENTION Since the automatic large bag mounting apparatus according to the present invention is constructed as described above, the large bag mounting rate, the mounting speed are improved, and the holder is replaced according to the change of the large bag type. The complexity of work etc. has been eliminated and work efficiency has been improved.
