Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel device that automatically binds the opening of a food storage bag using tape.

Conventionally, when binding the opening of a food storage bag using tape, the opening of the food storage bag was manually squeezed or twisted, and then forced into the tape wrapping means. was needed.

Therefore, not only is the work efficiency of tying the opening of the food storage bag low, but also there are disadvantages such as the formation of calluses on the fingers of the operator. Furthermore, since the efficiency of tying the mouth part is low, even if the process of packing foods and the like into storage bags is automated, the efficiency of the series of steps cannot be improved.

The present invention solves the above-mentioned drawbacks by providing a device that holds a storage bag filled with food, etc. in an upright state while holding the opening of the storage bag under pinching pressure, and wrapping a tape around the opening of the storage bag while holding the pinching pressure. This will be explained in detail below with reference to the accompanying drawings showing examples.

Fig. 1 is a front view of the mouth binding device of the present invention, Fig. 2 is a sectional view of Fig. 1, and Fig. 3 is a - of Fig. 1.
It is a sectional view showing a conveying means 2 for conveying a storage bag 1 filled with food etc. in one direction in an upright state, and a storage bag 1.
A clamping means 3 that clamps the upper end portion in a direction perpendicular to the conveying direction, a holding means 4 that clamps in the clamping direction and maintains the clamping state, and a tape that wraps the tape near the clamping pressure holding portion. It consists of a winding means 5.

The conveyance means 2 includes a rotary cylinder shaft 6 connected to a prime mover (not shown) and rotated in one direction at a predetermined speed.
A plurality of storage bag holding frames 7, 7... are provided at predetermined positions at equal intervals, and furthermore, a receiving plate 8 for supporting the storage bag 1 is provided approximately halfway around the lower part of the storage bag holding frames 7, 7... It crosses over and adheres to a predetermined fixed location.
The storage bag holding frame 7 is a U-shaped frame when viewed from above, and the side surface in the traveling direction is open. Furthermore, the traveling speed is synchronized with the speed of the packaging device and the like.

The clamping means 3 consists of a pair of rods 9, 9 fixed to a predetermined fixed portion above the receiving plate 8, and the distance between the rods becomes smaller in the direction of movement of the storage bag holding frames 7, 7... In addition, the portion with the smallest interval is positioned above the center of the receiving plate 8.

The holding means 4 is provided with a plurality of pairs of clamping pressure holding rods 11 and 12, which are biased in opposite directions by springs 13 and 14, at predetermined positions of the plate material 10 fixed to the rotary cylinder shaft 6. A fixed cam 15 is fixed above the clamping pressure holding rod 11 and the fixed cam 15 is engaged with each other via a roller 16. Then, the notched gear 19 is fixed to the rotating shaft 17 of the clamping pressure holding rod 11, and the rotating shaft 1 of the other clamping pressure holding rod 12 is fixed.
A gear 20 that meshes with the notched gear 19 is fixed to 8, and when the clamping pressure holding rod 11 is rotated against the spring 13 by the roller 16 that engages with the fixed cam 15, the clamping pressure holding rod 12 is connected to the spring 14. It is designed so that it can be rotated against resistance. Further, concave grooves 21 and 22 for holding the clamping pressure are provided at the mutually opposing ends of the clamping pressure holding rods 11 and 12.
are provided, and the clamping pressure holding rods 11 and 12 are connected to springs 13 and 14.
When the bag is rotated against this, the space formed by the grooves 21 and 22 is positioned directly above the center of the storage bag holding frame 7.

Furthermore, while the storage bag holding frame 7 moves from the narrow space between the rods 9, 9 to the tape winding means 5, the clamping pressure holding rods 11, 12 are held in a rotated state against the springs 13, 14. The shape of the fixed cam 15 is determined accordingly.

The tape winding means 5 includes an adhesive tape roll 23 that is rotatably supported, a gear 24 that guides the adhesive tape, a guide member 25 that directly faces the gear 24 for holding the adhesive tape, and a storage bag 1 that is connected to the gear. 24
This is a conventionally known configuration having a cutting blade 26 that cuts the adhesive tape when it passes between the adhesive tape and the guide member 25.

In addition, 27 is a hopper provided directly above the widely spaced part of the rods 9, 9, 28 is a plate material biased by a spring 29 so as to temporarily cover the opening of the storage bag holding frame 7, It is rotated against the spring 29 as the storage bag holding frame 7 moves. Also,
30 is a cushioning material made of synthetic resin or the like, and 31 is a cover plate that covers the upper part of the fixed cam 15.

The operation of the mouth binding device having the above structure is as follows.

Preparation for the mouth binding operation is completed by rotating the rotary cylinder shaft 6 in synchronization with the packaging speed of the packaging device (not shown).

Therefore, when the storage bag 1 filled with food such as sausage is put into the hopper 27, the storage bag holding frame 7 is located directly below the hopper 27, so that the storage bag 1
It can be supported in an upright state by the receiving plate 8 and the storage bag holding frame 7, and thereafter slides on the receiving plate together with the storage bag holding frame 7. Note that when the storage bag 1 falls from the hopper 27, the clamping pressure holding rods 11 and 12
are rotated in the direction of separating from each other by springs 13 and 14, and do not prevent the storage bag 1 from falling at all.

Next, when the storage bag holding frame 7 moves, the storage bag 1 is first firmly pushed into the inner part of the storage bag holding frame 7 by the plate 28, and when the storage bag holding frame 7 further moves, the plate 28 is pushed into the innermost part of the storage bag holding frame 7. Rotate against the spring 29.
Further, as the storage bag holding frame 7 moves, the upper end portion of the storage bag 1 moves between the pair of rods 9, 9 toward the narrow space, so the upper end portion is moved perpendicularly to the direction of movement. It can be clamped in the direction.

On the other hand, the clamping pressure holding rod 11 is rotated by a fixed cam 15 and a roller 16 against the spring 13, and a gear 20 meshing with the clamping pressure holding rod 12 and the notched gear 19
Since it rotates against the force of the spring 14, the portion near the upper end can be clamped in the direction of movement.
Here, the clamping operation by the clamping pressure holding rods 11 and 12 is completed when the upper end portion of the storage bag 1 moves to the narrowest space between the rods 9 and 9, and continues until the tape winding operation is completed. The clamping pressure state is maintained.

Thereafter, by guiding the upper end portion of the storage bag 1 that is held under pressure and passing it between the gear 24 and the guide member 25, the adhesive tape can be wound around the upper end portion, and the adhesive Tape cutting blade 26
Then, the opening of the storage bag 1 can be bound with adhesive tape.

Finally, tighten the clamping pressure holding rods 11 and 12 with the spring 1.
The storage bag 1 is moved by the storage bag holding frame 7 while being rotated in the direction of separating from each other at 3 and 14, and is dropped from the end of the receiving plate 8, and is transported to the next process by a carry-out conveyor or the like 32. .

Although the embodiment in which only one hopper 27 is provided has been described above, the hopper 27 is provided at a position directly above each storage bag holding frame 7, and
A shielding plate (not shown) may be immovably provided directly below the shielding plate, and one through hole may be bored at a predetermined position in the shielding plate. With this configuration, the storage bag 1 can be placed in the hopper. This is convenient when manually loading the storage bag 1 into the hopper 27, since it allows more time for loading the storage bag 1 into the hopper 27.

Further, the present invention is not limited to the above embodiments at all, and it goes without saying that various design changes can be made without changing the gist of the present invention.

As described above, in the present invention, by arranging various work processes concentrically, the apparatus itself can be significantly miniaturized, a large installation floor area is not required, and it can be configured compactly.

As mentioned above, various processes are arranged on concentric circles, and all operations are performed in conjunction by simply rotating the plate attached to the cylinder axis, so the power is also used to drive the plate. This reduces the cost of parts and eliminates the use of conveyor belts, which are the most likely to wear out, so there are fewer breakdowns and smooth operation.
In addition, the upper end of the food storage bag is automatically clamped to a small extent, and the bag can be bound with adhesive tape while still being clamped, which not only significantly improves the work efficiency of tying the opening, but also improves the work efficiency. It has unique effects such as completely eliminating defects such as calluses on people's fingers.
