Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides an automatic binding device that tightens and bundles objects to be bound before wrapping a binding tape around the objects and binding the objects. Regarding.

(Prior Art) Some known automatic binding devices are equipped with a bundling device that wraps binding tape around objects to be bound and tightens and bundles the objects before binding the objects. ing.

Such devices generally include a stage for placing objects to be bound;
! : It has a rotary disk equipped with a binding station and a falling stage, and the binding station is configured to wind and bundle the objects to be bound.

Here, to explain in detail how this winding and binding is performed, the binding tape unwound from the tape reel is stretched on a binding arm, and then pulled out from the tip of the binding arm and fixed to the machine frame. The objects to be bound are held by the tape holding device, and in this state, when the rotary disk is rotated through an angle, the objects to be bound adhere to the binding tape extending between the tip of the binding arm and the tape holding device, and this adhesive While the state is held, it rotates through an angle consisting of ＼ and then stops. Therefore, between the time when the objects to be bound are adhered to the binding tape and the time when the rotary disk is stopped, the objects to be bound are adhered to the binding tape, so that there is no connection between the adhesive part and the tape holding device. While the length of the tape between the two is kept approximately constant, the distance between the two varies in the direction of separation, so a tension is exerted on the tape between the two. Since the end of the tape held by the holding device is pulled out, not only does the adhesive part at the end of the tape winding become shorter after winding and binding, but in extreme cases, the tape holds the tape too short. There was a problem with it coming off the device.

(Object of the Invention) As mentioned above, in the above conventional example, from the time the objects to be bound adhere to the binding tape until the rotary disk stops, the tape between the liquid i portion and the tape holding device is The above-mentioned inconveniences occur due to the application of tension. In view of this, the present invention attempts to eliminate the above-mentioned disadvantages by relaxing the tension acting on the tape.

(Structure of the Invention) The present invention is provided in a rotary disk having a mounting station for objects to be bound, a binding station for binding the objects to be bound, and a dropping station for dropping the objects to be bound, in the middle of one rotation direction, and a bundled object placement section that rotates around the rotation center of the rotary disk.

The object to be bound is faced to the rotation area of the object to be bound which is set in the trap device, and the object to be bound is placed on the object to be bound between the loading station and the binding stage. A bundling device that straightens the bundle while tightening the tape and releases the bound objects wrapped with the binding tape from the beginning of the binding stage to the end of the falling stage; It has a binding arm for winding the tape around an object to be bound, and a tape holding device that cooperates with the binding arm to press the end of the binding tape and can move toward and away from the binding station, By starting the tape holding device to move toward the object at the same time when the object to be bound comes into contact with the tape extending between the tip of the binding arm and the holding device, the object to be bound placed on the placing section is When the rotary disk rotates through this angle, it comes into contact with the binding tape extending between the tip of the binding arm and the tape holding device, and at the same time as this contact, the tape holding device starts moving toward the binding station. Due to this approach movement, the tape between the adhesive part and the tape holding device is moved to the object-to-be-bound area, and when the tape holding device stops moving, the rotary disk also stops rotating at the same time. The tying arm then starts operating and winding and tying is performed, and when the winding and tying is completed and the tying arm returns to its original standby position, the one-turn disc starts rotating again. The wrapped and bound objects are dropped from the drop station, and the rotary disk rotates from there, rotates through the specified angle, and then stops, where new objects are placed. On the other hand, the tape holding device moves away and is located at the standby position before the object to be bound comes into contact with the tape.

#58 is rotated in the direction of arrow B in FIG.
A cam 45 is fixed to the bearing 40, and a cam 46 is rotated at the cam surface thereof.

Shafts 47 are installed on the side surface of the rotary disk 38 at 120 degrees symmetrical positions. A drive plate 48, which constitutes a part of the bundling means 4, is rotatably provided on this shaft 47. The drive plate 48 has a roller 49 and teeth 50, is urged in the direction shown by a spring 51, and is stopped from rotating by a stopper pin 51.

The roller A9 is configured to slide into contact with the cam surface 46 while the rotary disk 38 rotates. A gear 52 is provided on the side surface of the rotary disk 38, and the gear 52 is configured to rotate around a Vi shaft 53 as a fulcrum, and a bundling member 54 is provided to rotate integrally with the gear 52. The bundling member 54 is roughly composed of an arc-shaped bundling plate 55 and an elastic bundling rope 56, and the bundling member 54 faces the rotation range of 440 rotations of the objects placed on the object mounting section 41. During the process of the objects 44 being bound from the loading station to the binding station, the roller 49 of the drive plate 48 slides against the cam surface 46 and rotates, causing the drive plate 48 to rotate. The motion is transmitted to the gear 52 to rotate the bundling member 54, and the objects to be bound 44 are bundled while being tightened from the loading station to the bundling station. 7 is driven, and as shown in FIG. 2, the binding arm 8 is raised and the guide hole 12
．． 13 along the timing position side starting end 12A.

The binding tape 26 is attached to the object 44 as it is moved forward from the binding position end 13A toward the binding position end 12B, 12B.
The guide holes 12 and 15 are
ζ In this case, the longitudinal lengths □ are the same, and the timing position side starting end 13A is the timing position side starting end 1 so that the binding arm 8 is in a tilted state at the timing position.
3A is located closer to the bundling means 4,
The binding position side terminal end 12B is attached to the binding tape 2 on the object to be bound 44.
6 is wound, the end 12B on the binding position side is set so that the binding arm 8 is in a tilted state in order to press and cut the winding end.
It is arranged to be located on the side farther from the bundling means 4 than the bundling means 4. After the objects 44 are bound by the bundling means 3, the pressure is released from the bundling station to the falling stage. It is supposed to be received and transported.

Here, a pasting brush 57 is provided on the support plate 28' so as to face the winding end of the binding tape 26 wound around the object 44, and this pasting brush 57 covers the winding end. The spring 51 and the stopper bin 51 are designed to improve the appearance of the bundled items by pasting them on the bundled items 44. It has the function of preventing swinging.

Next, the operation of the device having the above configuration will be described. As shown in FIG. 2, after the objects to be bound are placed on the loading station, when the rotary disk 38 rotates through the angle, the objects to be bound come into contact with the binding tape 26, and a detection means (not shown) detects the objects. When this is detected, the air cylinder 27H is activated and the piston rod 27I is extended, so that the tape holding device 27 begins to move toward the binding stage. While this tape holding device 27 continues to move, the one-turn disc 38 is also rotating, so the tape between the object to be bound and the tape holding device 27 is stuck to the object to be bound. Then, as shown in FIG. 3, when one object to be bound reaches the binding station,
stops, and at this point the tape holding device 27 also stops.
7 and stops moving.

Then, when the rotary disk 38 stops rotating, the binding arm 8 is activated and the object to be bound is wound and bound, and when the winding and binding is completed, the rotary disk 38 starts rotating again and falls. The objects to be bound will fall when they reach the station.

On the other hand, since the piston rod 27I contracts when the winding and binding is completed, the tape holding device 27 is separated from the binding station.

(Effect of the invention) As is clear from the above, in the present invention.

The tape holding device starts moving toward the object at the same time as the object comes into contact with the binding tape extending between the tip of the binding arm and the holding device. Excessive tension is no longer exerted on the binding tape that stretches between the ends of the binding tape, and thus the end of the binding tape is prevented from being pulled out or detached from the tape holding device.

In addition, since the binding tape that extends between the objects to be bound and the tape holding device is attached to the objects to be bound before the objects reach the binding station, the tape portion and the tape portion are attached to the objects before the objects reach the binding station. There is no gap between the tape and the object to be bound, and therefore, there is no need to provide a means for pressing the tape portion against the object to eliminate such a gap, as in the conventional example, which simplifies the structure. In addition, by using such a means, the inconvenience of unnecessary tension being applied to the binding tape after one turn of binding can be eliminated.
