Description

Description: TECHNICAL FIELD The present invention relates to a tape sticking apparatus for packing a box body with a lid, which is covered with an adhesive tape at the joint of the lid and the lid.

(Prior Art) For example, in the fish market, a box made of styrofoam (toro box) is used to pack fish with ice. This box is also used for transporting pickles, vegetables, fruits and the like. In this shipping operation, the worker manually applied an adhesive tape to the joint between the box body of the toro box and the lid (generally a flat plate).

As a device for performing this work mechanically, Japanese Utility Model Laid-Open No. 1-6224
No. 9 discloses a tape sticking device.
This tape sticking device removes the peeling agent at the overlapped portion of the adhesive tape with a polishing roller, then sticks the tape at the joint between the body of the toro box and the lid, and then rotates the arm with a cutter blade. Is manually cut to cut the middle of the adhesive tape, and the tapes at the winding start and end are overlapped with each other.

Japanese Patent Application Laid-Open No. Hei 2-13569 discloses a tape affixing apparatus which improves the above-described manual tape cutting operation and mechanically performs this operation. The features of the configuration of this device are as follows. (See FIGS. 7 and 8) That is, the tape bonding drive arm (a), the cutter blade drive arm (b), the cutter blade rotating arm (c), and the link member (d).
A cutter blade arm (e) having a cutter blade (f) at a node between the tape bonding drive arm (a) and the cutter blade rotating arm (c) of the parallelogram link. The tape holding arm (g) is fixed to a node between the cutter blade driving arm (b) and the link member (d) of the parallelogram link, and the tape holding member (h) is attached thereto. It is.

With such a configuration, when the drive arm (i) is attached to a node between the tape bonding drive arm (a) and the link member (d) of the quadrilateral link and a rotational force is applied to the node, this node is connected. The quadrilateral link pivots while pivoting at another node about the center.

When the tape holding member (h) turns to the position where the tape can be pressed, the node serving as the center of rotation of the quadrilateral link and the node to which the tape holding arm (g) is fixed are fixed. That is, the link member is fixed. In this state, the tape bonding drive arm of the quadrilateral link (a)
When the cutter blade driving arm (b) is turned, the cutter blade rotating arm (c) rotates and the cutter blade (f) protrudes to cut the tape.

(Problems to be Solved by the Invention) By the way, the tape attached to the joint between the box body and the lid is cut after making a round around the periphery.
It is desired that the length exceeding one round, that is, the length of the tape to be overlapped, be lengthened or shortened depending on the contents accommodated in the box.

In the above-mentioned conventional tape sticking apparatus, since the link mechanism is employed as the tape cutting means, the cutting position of the tape is constant, and it is difficult to change the tape cutting position.

In FIG. 5, reference numeral 60 denotes a carry-in roller device, and a stopper 61 for a toro box is provided on the tape affixing device 1 side so as to be retractable by an air cylinder or the like (not shown). Reference numeral 62 denotes an unloading roller device, which is a tape sticking device 1
On the side, an approach switch 63 for detecting the end of the toro box W is provided. The roller devices 61 and 62 are continuously rotated by an electric motor.

Next, the operation of the present embodiment configured as described above will be described.

In the tape attaching device 1, the toro box W after the work is completed
Is transferred onto the carry-out roller device 62 by the slide roller 7 on the rotary table 2, and when the end portion of the toro box W is detected by the proximity switch 63, the stopper is stopped on the carry-in roller device 60 by the stopper 61. The rotation of the carry-in roller device 60 causes the next toro box W to be rotated by the tape attaching device 1.
Is transported and placed on the turntable 2 of the.

At this time, the toro box W is transported by the slide roller 7, moves down while falling down on the reverse stopper 12, and further stops against the stopper 11. When the toro box W has passed over the stopper 12, the reverse return stopper 12 stands up and supports the rear end of the toro box W.

Toro box W on rotary table 2 is fixed by holding means 13. Next, the cylinder 19 is operated to remove the release agent from the adhesive tape T by rotating the polishing roller 23. Next, the rotation of the polishing roller 23 is stopped, and the electric motor 5 is driven to rotate the turntable 2. Thus, the adhesive tape T is pressed and adhered to the side surface of the toro box W by the polishing roller 23 and is pulled out. The pressing force at this time is adjusted by the cylinder 19.

Next, when the toro box W has reached a position where the adhesive tape T is to be pasted about one turn, the turntable 2 stops,
The following operation is performed.

The drive cylinder 22 operates, and the drive arm 2
6. Rotate the tape bonding drive arm 27. During this turning process, the tape pressing member 30 contacts the roller 24 and presses the adhesive tape T.

On the other hand, due to the above rotation, the adhesive tape T is
At the same time as being pushed out by the cylinder 20, the operation of the cylinder 19 causes the polishing roller 23 to move away from the
Is rocked, and the adhesive tape T stretched by the polishing roller 23 is sequentially removed from the surface of the polishing roller 23 by the pressure roller 20.

Next, as shown in FIG. 6, when the adhesive tape T is extruded to the release agent removing portion t, the adhesive tape T is tightly stretched between the pressure roller 20 and the tape pressing member 30. It is in. At this time, the cutter blade driving cylinder 28 is operated, the cutter blade 21 is protruded to cut the adhesive tape T, and the cutter blade 21 is returned to the original position. Then, the adhesive tape T is pressed against the separation processing part t in the process of being extruded by the pressure roller 20, and the cut end of the adhesive tape T is bonded.

The cutting length of the adhesive tape can be adjusted by changing the operation length or operation timing of both rods of the driving cylinder and the cutter blade driving cylinder 28.

Next, the drive cylinder 22 is operated to return the drive arm 26 and the tape bonding drive arm 27 to the original position, and at the same time, the bonding arm 16 is swung by the cylinder 19a to move the polishing roller 23 to the original position. He is ready for the next task.

After the operation is completed, the cylinder 35 is operated, the rod 40 is extended, the link 38 is erected and abuts the bar 33 to rotate it. Thereby, the stopper 11 comes off from the front end of the toro box W, and the toro box W on the turntable 2 can be moved. Further, the bar 33 is released by the switch 63 on the discharge conveyor, and the stopper 11 is raised by a spring or the like (not shown). Then, the next toro box W is loaded onto the turntable 2 and the same operation is repeated.

(Effect of the Invention) Since the present invention is configured as described above, the cutting length of the tape can be freely changed, so that the length of the tape to be superimposed on the pasting start end can be changed. Therefore, even when the overlapping depth is required depending on the type of the stored items, the processing can be easily performed, so that time is not required for adjusting the apparatus. In addition, since the tape bonding drive arm and the cutter blade are driven by the cylinder, the tape bonding can be automated. Further, the structure was simplified, and the reliability of the device could be improved.
