Here, the control of this embodiment will be briefly described based on the block diagram shown in FIG. Control unit 20
Reference numeral 0 denotes a drive unit (not shown) of the table unit 2, the clamp unit 3, the tape supply unit 4, the fastening unit 5, the large bundle lifting / lowering unit 6, and the large bundle turning unit 7 (all of which are referred to as a small bundle group binding mechanism). Are controlled so as to wind and tape the tape 46 around the small bundle group 8 in a cross shape. In addition, the control unit 200 of the present embodiment detects that the shutter is closed. Detection means 202 for detecting that the small bundle group 8 is loaded in the concave portion 17a of the table means 2.
The small bundle group binding mechanism automatically starts the binding operation based on the detection signal from the small bundle.

Next, the operation of this embodiment will be described with reference to FIGS.
It will be described based on. The following operation is performed by the control unit 200.
Shall be performed by (A) (see FIG. 11A) The shutter 43 is manually opened, and the small bundle group 8 is
7a, when the shutter 43 is closed, the presence / absence detection means 202 detects that the small bundle group 8 has been set in the recess 17a of the table means 2, and the shutter 4
3 is closed by the closing detection means 201, and the control unit 200 automatically starts the binding operation based on these detection signals. When the binding operation is started, the motor 29 of the clamp means 3 is driven to move the clamp plates 32 and 35 in the clamping direction. At this time, the clamp plate 35 presses the clamp plate 33 that is not driven by the motor 29 and, at the same time, clamps the vicinity of the front end of the tape 46 fed out between the clamp plate 33 and the small bundle by driving the motor 56. The group 8 is moved in the clamping direction. At this time, the clamp plate 33 is
Therefore, when the tape is pressed by the clamp plate 35, the tape 46 is moved in the clamping direction of the small bundle group 8 together with the clamp plate 35 when the tape 46 is pressed by the clamp plate 35. It is possible to do. When the clamp plates 32 and 35 are moved by a predetermined amount (at this time, the small bundle group 8 is not completely held by the clamp plates), the small bundle alignment member 65 is moved into the concave portion 17a with the movement of the clamp plates 32 and 35. The end of the group of small bundles 8 that has been moved and set irregularly is pressed and aligned, and then the group of small bundles 8 aligned is clamped by the clamping means 32, 33, 35.

(B) (Refer to FIG. 11 (b)) When the clamp plates 32, 33 and 35 are driven in the clamping direction and a predetermined time has elapsed, the motor 20 of the table means 2 is driven and the turntable 16 is rotated. Clamp plate 3
The tapes 3 and 35 are turned while holding the leading end of the tape 46, and the tape 46 is wound around the small bundle group 8. At this time, the drive roller 47 of the tape supply means 4 is rotated in the feeding direction of the tape 46. Since the torque of the torque limiter 58 is applied to the drive roller 47, the small bundle group 8 is wound once. Also in this case, a constant tension is applied to the tape 46 so that the tape 46 can be wound around the small bundle group 8 with a predetermined strength, and after the turntable 16 is rotated once (360 °). Even if it is stopped, the tape 46 on the turntable 16 does not sag.
Further, when the clamp plates 33 and 35 clamp the leading end of the tape 46, the convex portions 37 and the small holes 38 provided on the clamp plates 33 and 35 are fitted to each other. Is pulled out with a predetermined strength, the protrusions 37 and the small holes 38 restrict the pulling-out of the tape 46, and can prevent the binding failure.

(C) (See FIG. 12 (c)) When the turntable 16 is rotated once (360 °), its rotation is stopped and the heating member 6 heated at a predetermined temperature is turned on.
7 is moved from the standby position toward the clamp plate 35.
Then, the front end face in the moving direction of the heating member 67 presses the overlapping portion of the tape 46 in which the small bundle group 8 is wound once to the clamp plate 35 side, and thereafter, the clamp plate 33 extends along the overlapping surface of the tape 46. Moved in the direction. At this time, when a torque is applied to the drive roller 47 described above, the cutter 89 provided on the heating member 67 cuts the tape 46 stretched at a predetermined strength, and the heating member 67
The tape 46 is adhered to the tape 46 by heat while pressing the doubly overlapping tape 46 along the holding surface of the clamp plate 33, and the one-way binding is completed.

(D) (See FIG. 12 (d)) The heating member 67 of the fastening means 5 to which the tape 46 has been thermally bonded is moved to the standby position, and the tape 46 remaining unbound after cutting is removed from the tape 46. The motor 56 of the supply means 4 is driven, the drive roller 47 is rotated in the take-in direction, and the leading end of the tape 46 is temporarily suspended at the outer peripheral position of the turntable 16.

Next, together with the small bundle group 8, the clamp plates 32, 33, 35 bound around the small bundle group 8 by the tape 46.
The small bundle bound to the tape 46 is driven by driving the motor 112 of the large bundle lifting means 6 to raise the lifting table 117 from the standby position and to push up the small bundle group 8 from below to a predetermined height position. It is pulled out from the bundle group 8. At this time, the tip of the tape 46 bound by the convex portion 37 and the small hole 38 of the tape slip preventing means 172 provided on the clamp plates 33 and 35 is held in a state of being clamped to prevent pulling out. If the tape 46 is pulled out, the tape 46 will be damaged. Therefore, the convex portion 37 and the small hole 38 which hold the leading end of the tape 46 in a direction opposite to the direction in which the motor 29 of the clamp means 3 holds the small bundle group 8 are separated by a predetermined distance. Driven to position. Further, even if the clamp plate 35 is driven in the reverse direction, the movement of the inner clamp plate 33 is restricted by the frictional resistance of the slip clutch 42, so that the position of clamping the small bundle group 8 does not move. ,
A predetermined space can be provided between the clamp plate 33 and the clamp plate 35.

If the clamp plate 32 is also driven in a direction opposite to the direction in which the motor 112 is clamped, the tape 46 to be bound may be cut. However, the clamp plate 32 is clamped by the urging member 31. The clamp plate 32 is not moved even if the slide block 23 is moved by a predetermined amount because the clamp plate 32 is moved in the predetermined direction. The small bundle group 8 bound in one direction is clamped by clamp plates 32, 33,
35 and the lifting table 117
Is raised to a position where the clamp rods 102 and 103 of the large bundle turning means 7 can clamp a predetermined position of the tape 46 bound to the small bundle group 8.

(E) (See FIG. 13 (e)) When the small bundle group 8 is raised to the position where it is clamped and turned by the large bundle turning means 7, the clamp plate 3 of the clamp means 3 is turned on.
2, 33 and 35 are moved to the standby position, and the clamp rods 102 and 103 of the turning means 7 are shifted from the center (center of gravity) of the small bundle group 8 by driving the motor 95 in a predetermined direction. Is moved in the direction of pinching. When the clamp rods 102 and 103 clamp the small bundle group 8, the lifting table 117 of the large bundle lifting / lowering means 6 moves from the position where the small bundle group 8 is placed on the slide shutter 120 which is the bottom surface of the concave portion 17 b of the table means 2. The small bundle group 8 is rotated by its own weight as the lifting table 117 descends. Note that even if the rotation of the small bundle group 8 stops halfway, the pin 107 of the clamp
Is moved along the notch 119 of the plate cam 108, so that it is surely rotated 90 °.

When the clamp rod 103 clamps the small bundle group 8 and is further moved in the same direction, and the sliding shaft 104 of the clamp rod 103 is moved by a predetermined amount, it is detected by a sensor (not shown). The lifting table 117 of the means 6 is raised again from the position above the slide shutter 120, which is the bottom surface of the concave portion 17b of the table means 2, to place the small bundle group 8 thereon. The position at which the elevating table 117 is raised is raised to a position higher than the height position of the bottom surface of the small bundle group 8 rotated by 90 ° by a predetermined amount. When the small bundle group 8 is received, it always comes into contact with the small bundle group 8 and is stable. Received.

(F) (See FIG. 13 (f)) The clamp rods 102 and 103 of the large bundle turning means 7 are
Is moved in the direction opposite to the direction in which it is clamped, is delivered to the lifting table 117 of the large bundle lifting / lowering means 6, and is moved to the standby position. Further, while the elevating table 117 is lowered to a position above the slide shutter 120 which is the bottom surface of the concave portion 17b of the table means 2 with the small bundle group 8 placed, the elevating guide member 53 of the tape supply means 4 is When the drive roller 47 is lowered from the standby position onto the turntable 16 by the driving of the motor 60 and the driving roller 47 is rotated in the feeding direction together with the driving of the motor 56, the leading end of the tape 46 is guided by the guide member 53 in the feeding direction. Moved to
The tape 46 is inserted between the clamp plate 33 and the clamp plate 35 of the clamp means 3 at the standby position to prepare for the next binding operation, and when the tape 46 is fed to the above position, the guide member 53 is again in the standby state. Raised to the position. An elevating table 117 places the small bundle group 8 and a slide shutter 120 on the bottom surface of the concave portion 17 b of the table means 2.
When the small bundle group 8 is lowered to the upper position, the small bundle group 8 is lowered into the concave portion 17b. At this position, the small bundle group 8 is bound in only one direction.
Are bound in the direction along the short side direction of.

(G) (see FIG. 14 (g)) The small bundle group 8 at the above position is
The same operation as in (c) and (d) is performed, and the tape 46 is bound in a cross shape. When the bundled small bundle group 8 is selected to stamp on the cut surface by the selection means,
The position where the tape 46 intersects is stamped. In this case, the clamp plates 32 and 33 for holding the small bundle
After the table 35 is pulled out as the lifting table 117 rises, the lifting table 117 is temporarily lowered to the standby position while the small bundle group 8 is mounted. Then, after that, the turntable 16 of the table means 2 is rotated by 180 °, and the elevating table 117 is raised to a predetermined position as described above. Then, the sliding arms 93 and 94 are driven in the clamping direction, and the stamping member is moved. 166 stamps the above-mentioned location (the position where the tape crosses the cut surface).

Further, after being stamped, the sliding arm 93,
94 is moved to the standby position and the lifting table 1
17 is again lowered to the position above the slide shutter 120 which is the bottom surface of the concave portion 17b of the table means 2 while the small bundle group 8 is placed thereon, and the clamp plates 32, 33,
If the position of 35 is left as it is, it is 180 ° opposite to the position at the start of binding, so that the turntable 16 is further rotated by 180 °. When the turntable 16 rotates by 180 °, the lifting / lowering table 117 on which the stamped small bundle group 8 is placed is raised, and moves to a position where the small bundle group 8 bound by hand is easily taken out (standby position of the lifting table 117). Is done. When stamping the non-cut surface of the small bundle group 8 bound by the selection means, the tape 46 is bound in a cross shape, and then the elevating table 117 is raised as it is to a predetermined position. 93 and 94 are moved in the clamping direction, and the stamping member 166 is moved.
Is stamped, and the elevating table 117 on which the stamped small bundle group 8 is placed is lowered from that position to the standby position.

When the lifting / lowering table 117 on which the bundle 8 of small bundles is placed is moved to the standby position, the vertically movable guide member 53 of the tape supply means 4 is again turned from the standby position by driving the motor 60. While being lowered onto the table 16, the drive roller 47 is rotated in the feeding direction together with the driving of the motor 56, and the leading end of the tape 46 is again moved between the clamp plate 33 and the clamp plate 35 of the clamp means 3 at the standby position. To prepare for the next binding operation, the guide member 53 is again raised to the standby position, and the binding operation is completed.
