A table 57 is placed on the base of the strapping mechanism 55 and is placed on the same surface C as the top surface of the bottom member 35 described above.
Can be installed in two ways. The round rods 50 are inserted into the lower end position (- when ζ: is the table 57 (two longitudinal grooves are inserted) so that they are at a lower position than the top surface of the table 57. Rubber tape or a piece of cloth 58 (FIG. 6(d)) with one end fixed to the spring is attached. Also, the trapezoidal plate 47 and the horizontal plates 48, 49 (two of these drive cylinders are integrally connected to the 11th air cylinder). C2 is attached so that it can be moved in the vertical direction by a cylinder 59.

The operation of this automatic packing machine (I will explain it in two parts. For example, the second
As shown in the figure (-), the objects 3 to be packed are rotated 90 degrees from the position shown in FIG.

The subsequent operations are performed in sequence. A switch (not shown) is turned on, and then the pair of movable members 31 are moved in a direction perpendicular to the plane of the paper so as to approach each other, thereby serving as a back plate for the object to be packed 3. When the third cylinder 28 is actuated, the movable member 31, the third plate 27, and the movable body 26 integrally slide on the first plate 23 and move to the right (two times), leading to the tip of the object to be packed 3. hits the stopper plate 32 and stops.Then, the first cylinder 20 and the second cylinder 2
1 is activated, the third plate 27, the movable body 26, and the first plate 23 rise, and the upper surface of the object to be packed 3 hits the second plate 24 while lifting the sheet 34 upward. If the air pressure of the first air cylinder 20 is made relatively (2) larger than the air pressure of the second air cylinder 21, the first plate 23 compresses the object 3 while compressing the second plate 24.
is pushed up, and the upper surface of the third plate 27 becomes the movable bottom member 35.
It stops when it becomes flush with the top surface of. At this time C

Yu naru. Incidentally, the fourth cylinder 36 has a mil> of the object to be packed 3.
Since they are arranged sideways from each other, they do not come into contact with each other.

Fourth cylinder 36 is then actuated. The bottom member 35 is driven to the left in the figure (while pushing the plate 27 and the movable body 26). Bottom member 3
While the roller 37 at the top of the sheet 34 closes the left U-shaped side of the sheet 34, the remaining rollers 37 close the object 3 to be packed.
While rotating along the lower surface C1, the bottom member 35 stops at a position where the lower die 38 and the heat sealing upper die 39 correspond. Then, the upper die 39 is lowered by the lower die 38 (two sides) and heat-sealed two strips, and the cutter 40 (two sides) cuts the middle between them. As a result, the ring-shaped purple wrapping is completed. , both ends of the rolled wamp are joined by heat sealing, while sheet 34 is also heat sealed (-

The rolls 33° and 33' consume more resonance than the unwinding opening, but the consumption of the lower roll 33' is somewhat greater.

When the winding is completed, the mechanism described above is returned to its initial position (-) and is ready to supply the next object 3 to be packed.

The roller 37 of the bottom member 35 is rotated in the left direction (-
When moving forward (2 is free and rotates, it is easily moved (-) along the bottom (2) of the object to be packed 3 in the left direction, and when it returns to the right, the roller 37 rotates clockwise (2 rotations). There are 3 unwrapped objects to be packed on top of this.
is above the bottom member 35 in the position shown in FIG.

At this time, the state of the packaged items in the unrolled container is shown in Figure 3 (a).
(-Equivalent to the one shown. However, since it is compressed and unwound, it is not angular but somewhat rounded.The 8146 cylinder 45 is then actuated to lower the transfer member 46 and continue. By the operation C of the fifth cylinder 42, the object to be packaged 3TL is transferred to the bending position 15.

Subsequently, both ends of the wamp of the article to be packaged 3 are bent and a string is attached. The trapezoidal plate 47, the horizontal plates 48 and 49, and their driving cylinders are lowered to a predetermined position @c from the operation exposure of the eleventh cylinder 59 without being separated. Then, the eighth and ninth cylinders 52.53 are activated and the horizontal play is performed as shown in FIG.
When the wamp is driven outward and inward, the surplus portions 5 at both ends of the wamp are first bent inward along the perpendicular sides. Next, when the pair of seventh cylinders 51 are activated and the pair of plates 47 having a substantially trapezoidal outer shape are driven in one direction (FIG. 6(b)), the wamp end 5 is driven forward C2. Upper C of horizontal plate 48, 49 - horizontal upper edge is bent and bent. Subsequently, when the tenth cylinder 54 is actuated, the round bar 50 is driven upward (Fig. 6 (cl.
), fold the remaining portion of the wamp end 5 upwards.

? The bending is completed as shown in Fig. The extra part 5 of the wamp, which is wider than the object to be packed 3, can be placed below the top surface of the table 57 to allow it to slide smoothly into a predetermined position without damaging it. The width C''' - especially in the vertical direction (1) is narrowed, and the Nicom tape 58 is closed. This makes the length h ('4S
Even if the shape of the round bar 50 (Fig. 6 (C)) changes, if the round bar 50 (2-twist bending is used, especially if h is short, the rubber tape 58 should be used to hold the edge) It is.

Then the trapezoidal plate 47 and the horizontal plate 48.4
9 is returned to its original position C2, and while the round bar 50 and rubber tape 58 are held in place at the ends, stringing (FIG. 6(d)) is carried out. Subsequently, when the 10th cylinder 54 and the 11th cylinder 59 are released, they are all returned to their original positions.The item 3 to be packed, which has been completely hooked, is pushed out by the next item to be packed, and a stopper is placed at the tip of the slope. Formed stopper plate 60 (Fig. 4B)
Wait above.

4B and 7 (-5) The palletizer device 70 according to the present invention (second aspect) includes a hydraulic lift 72, which is a mechanism for placing the pallet 70 in a predetermined position, and a means for transporting objects to be packaged. ).The pallet 71 is connected to the conveyor 7.

As shown by two arrows E, the distal end C is comprised of a claw 79 which is rotatably mounted. The claws 79 hold the string 6 as shown in Figure 8A.
9a.

79b has no pair, and claws 79a and 79b are mutually (1 and 79b)
In Figure A, there are two pairs of such claws separated by a certain distance, and in Figure 10, there are three pairs of claws. There is.

Air cylinder 78 has one defined actuating stroke, and in its most extended position, as shown in FIGS. 8B and 9 (=one pawl 79a).

79b presses down on the top surface of the object to be packed 3, so that the string 6 is floating near the claws. 2WjA
When he stirs, the string 6 grabs him as shown in Figure 8C.

As shown in FIG. 4B, a phototube 80 is provided to detect the height of the first object to be packaged 3 loaded on the barrequiser device C; Once the planned number of items to be packed (three items) are loaded on the top shelf, the hydraulic lift will descend.
The height of the upper surface of the object to be packaged 3 on the uppermost stage is almost the same as the height of the upper surface of the stopper plate 60 (2 is o. Therefore,
When the object to be packaged 3C is used, the air cylinder 7F3 only needs to be moved up and down in a timely manner, and height control is not necessary. Therefore, as a control device for the palletizer device, a simple X-Y mechanism in which the horizontal movement of the transverse support beam 77 and the air cylinder 78 is programmed is used. can be used. - Example of a program (FIG. 7 shows a stage consisting of objects 3 to be packed that are loaded from two sides, and it is well known that the next stage is stacked backwards to prevent the cargo from collapsing.) Also, it is clear that the gripped object to be packed 3 (the index number) can be removed by lowering the air cylinder 78 and opening the claws 79a, 79bY. During package transfer (1).
