Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is directed to a futon made by filling the inside with cotton material as shown in Fig. 1 in the manufacturing process of futons such as sitting cushions. The present invention relates to a device for automatically transporting and supporting a cotton material, and spreading the cotton material over the squares (cutting corners).

(Prior art) In the conventional futon cornering work, the worker holds the futon after it has been woven, inserts it diagonally from above into the insertion slot of the futon cornering machine, and manually inserts/removes the futon and corners. The corners were cut using the rotating hammer of the corner cutter while turning the paper and turning it inside out.

However, this work not only requires a great deal of skill, but also involves holding the futon for a long time during the work, inserting and removing it, turning the front and back sides six times, and reversing the front and back. bad. In addition, work-related problems such as vibrations in hands and arms during work, health problems due to inhalation of dust, and injuries caused by hands getting caught in the slot of the cornering machine are caused.

(Problems to be solved by the invention) In view of the conventional circumstances, this invention solves the following problems:
To provide a device that can fully automatically round out the corners of a futon after it has been knitted.

[Structure of the Invention] (Example) To explain the following with reference to the embodiments shown in the drawings, as shown in FIGS. It consists of a futon conveying support device B and a futon squaring machine C installed on the side opposite to the futon extrusion device A.

First, the futon extrusion device A is equipped with a one-piece futon extrusion frame 2 that intermittently moves back and forth along a guide rail 5 provided on a workbench 1 via a pulley 4, and a part of the workbench 1 at the extrusion portion of the extrusion frame 2. A notch 3 for passage of a futon holding arm, which will be described later, is provided. Note that S is an operating switch for the extrusion frame 2.

Next, the futon conveying and supporting device B is provided with a movable column 7 that intermittently reciprocates back and forth on the base 6 via a rack mechanism 13 (a rack 13a and a rack pinion 13b driven by a motor M1).

Upper and lower futon holding arms 9a and 9b, which are provided with intermittent masseter muscle action on the movable column 7 via a hydraulic cylinder 14, are moved vertically upward at a predetermined angle by a motor M2 via an elevating frame 7a that is moved up and down intermittently by a motor M3. Pivotally mounted to allow intermittent reversal movement within a range.

Further, as shown in detail in FIG. 4, a transmission system (driving pinion 21 of motor M4, transmission chain 23, driven pinion 22, rotating shaft 11 ) is attached to the futon handle 10a which is driven intermittently in horizontal rotation, and a futon handle 10b which can freely rotate horizontally is attached to the upper corresponding portion of the lower futon holding arm 9b.

Finally, the futon squarer C has a rotating shaft 18 that is driven by a motor M5 and a transmission system 17 in an intermittent forward/reverse manner mounted inside the casing 15, and both ends of the rotating shaft 18 are fixed vertically. A rotary beating rod 16 is installed between the rotary rods 19.

A side portion of the casing 15 facing the futon conveying and supporting device B is provided with an insertion opening 20 through which the futon K held by the futon holding arms 9 (9a, 9b) faces from an upwardly inclined position.

Then, the movements of the movable parts of the respective devices, namely, the reciprocating movement of the futon extruding frame 2 of the futon extruding device A, the reciprocating movement of the movable column 7 of the futon conveying support device B, the masseter muscle movement of the futon holding arm 9, and the vertical upper reversal. The movement, the horizontal rotational drive of the futon handle 10a, and the forward and reverse rotation of the rotary beating rod 16 of the futon squarer C are set to be driven intermittently intermittently by an electrical control system.

In addition, 24 in the drawing is the upper futon holding arm 9a.
It is a futon support frame protruding from the tip of the futon K, and has a length slightly closer to the center than the corner k of the futon K, and the upper futon holding arm 9a is inverted and positioned on the lower side.
When the corner of the futon is struck from above by the rotating beating rod 16, it functions as a support from below.

[Operation] In order to square a cushion using the proposed device having the structure of the above embodiment, in FIGS. Place it in the extrusion frame 2 and turn on the operating switch S. Then, the extrusion frame 2 is extruded in one pitch, and when it is located at the extrusion part, the movable column 7
moves backward and stops, and while the lifting frame 7a is lowered, the futon holding arms 9a, 9b operate the masseter muscles to pick up the futon 10a, 1 from above and below the center of the seat cushion K.
Clamp by 0b.

Then, at the next moment, the movable column 7 moves forward to a predetermined position and stops while the lifting frame 7a rises, and during this time the clamping arms 9a, 9b are reversed within a predetermined angle range vertically upward (thereby, the clamping arms 9a, 9b, the vertical position is reversed).

Then, at the next moment, the movable column 7 further moves forward slightly and stops, and one corner k of the seat cushion K in the pinched state is inserted into the insertion opening 20 of the cornering machine C from diagonally above.

Then, the rotary beating rod 16 of the cornering machine C first rotates in the counterclockwise direction and repeatedly strikes one corner k of the cushion K from above. After beating the futon K a predetermined number of times, the futon handle 10b located at the lower side rotates to turn the futon K by a predetermined angle so that the next corner k faces the insertion opening 20.

When the squares on the front side are finished, the rotary beating rod 16 is then turned in the opposite direction and hits one corner at a time from the bottom side in the same manner as before.

That is, due to this beating action from the front and back, the internal cotton material moves to the corner K of the seat cushion K, and the vibrations caused by the beating action combine to spread uniformly to the corners, so that so-called cornering can be performed. It is.

In order to induce this vibration effect more effectively, it is desirable to provide the clamping arm 9 with a slight amount of rotational play. Also, when hitting the corner k of the seat cushion K from below, the weight of the seat cushion acts, but when hitting from the top, there is nothing to support it below, so as mentioned above, the tip of the holding arm 9a is attached to the corner k of the seat cushion K. If the support frame 24 that supports the part slightly closer to the center than the corner k is provided in a protruding manner, the hitting effect can be further increased.

Furthermore, the movable support 7 is
By retracting (that is, moving back) little by little, the cotton material can be transferred more smoothly.

Now, when the cornering is completed, the movable support 7 moves back and the futon holding arm 9 turns over to the workbench 1 side.
At the limit of its backward movement, the clamping arms 9 open and become a product (hereinafter referred to as "cornered futon").
is lowered onto the workbench 1 (at this time, the futon push-out frame 2 has returned to the starting position, and the newly knitted seat cushion K is placed in the frame and is waiting).

Then, at the next moment, the futon extrusion frame 2 is pushed out, and along with this, the cornered futon that was lowered first is pushed laterally, and the seat cushion K in the frame is moved to the cornering process by the same movement of each part as before. Departing.

Thereafter, the cornering work is progressed by this repeated operation.

[Effects of the Invention] As described above, the device of the present invention has succeeded in switching the labor and effort of futon cornering work, which previously had to be done manually by a worker standing in front of the cornering machine, to a completely automated system. This can significantly improve work efficiency.

In addition, the accuracy, reliability, and stability of the movement of the futon holding arm, which is the main part, brings about uniformity of the product and significantly increases the commercial value.

Since it does not rely on human labor, problems related to work-related accidents have also been resolved.
Another major advantage is that the entire device is simple and does not take up much space, and the manufacturing cost is relatively low.

From the foregoing, the present invention is truly advantageous as it achieves the intended purpose listed at the beginning.
