Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape end processing device for a bag sealer that closes the opening of a plastic bag or the like with an adhesive tape.

When removing the contents from a bag whose mouth has been closed using this type of bag sealer that has been proposed in the past, the adhesive side of the end of the tape adheres to each other, making it extremely difficult to remove.

The present invention provides a tape end processing device for TUG SEALA that bends each end of the adhesive tape that has closed the mouth of a bag across the longitudinal direction of the tape so that the adhesive surfaces do not adhere to each other. The purpose is to provide the following.

Hereinafter, the present invention will be described with reference to the drawings showing one embodiment. The bag sealer tape end processing device of the present invention has two frame side plates 1, 1 (one side plate 5 is not shown). The guideway 2 is opened at the position where the guideway 2 is opened, and the both side plates 1
, a rotor 3 is rotatably mounted between 1 and 1, and a pocket 5 having a tape holding claw 4 on the edge of the opening and a notch 6 for accommodating the opening B of the bag A are alternately provided on the circumferential surface of the rotor 3. Arrangement: An actuating block 7 is slidably arranged between the two plates 1 and 1 on both sides, and a head 10 for bending the tape end, which is equipped with a cutter 9 at the tip and can move forward and backward into the pocket 5, is actuated. block 7
A tape presser claw 12 is connected to the shoulder 8 of the operating block 7 and presses the tape 11 against the tape holding claw 4 during cutting of the adhesive tape 11 and bending the end of the tape.
The actuating block 7 is actuated via an actuating lever 13 which is elastically supported on the guide path 2 and rotated by the opening B of the bag A moving down the guide path 2. The gist of the invention is that a tape pressure spring 14 is provided at the terminal end of the tape.

In the drawings, reference numeral 15 denotes a mounting shaft for rotatably mounting the rotor 3 to the side plate 1. Reference numeral 16 denotes a guide member that slidably supports both upper and lower surfaces of the actuating block T, and is provided protruding from the inner side j5 of the side plate 1.

Reference numeral 17 denotes a tension spring stretched between the rear end of the actuation block T and the side plate 1.

Reference numeral 18 denotes a spring that elastically supports the tape presser pawl 12 on the shoulder portion 8 of the actuating block 7.

Reference numeral 19 designates a pivot shaft that pivotally connects the operating lever 13 to the outside of the side plate 1, 20 designates a link that pivots to the rear end of the operating lever 13, 21 designates a center portion that is pivotally connected to the link 20, and a lower end portion that is pivotally connected to the link 20. is a link that is pivotally connected to the outside of the side plate 1 via a pivot shaft 22, and 23 is a guide elongated hole provided in the link 21.

24 is a pin protruding from the side of the operating block 7;
It engages with the guide slot 23 through a window hole (not shown) opened in the side plate 1.

25 is a extraction hole connected to the terminal end of the guideway 2;
is a mounting tool, and the lower end of the tape compression spring 14 is mounted between the side plates 1 below the extraction hole 25.

27 is a reel of the adhesive tape 11, and 28 and 29 are an upper guide roller and a lower guide roller for guiding the adhesive tape 11, respectively.

30 and 31 are terminals of the adhesive tape.

Reference numeral 32 denotes a guide hole opened in the side plate 1 (see FIG. 11), which guides the side portion 33 of the tape holding claw 12.

34 These are rubber legs attached to the lower surface of the side plate 1.

Next, the operation of the tape end processing device will be explained. When the adhesive tape 11 is pulled out from the adhesive tape reel 27 and blank-shot once, the state shown in FIG. 1 is obtained. Therefore, the mouth part B of the plastic bag A containing the appropriate items was gathered together by hand.
As shown in Fig. 3, it is pushed from the entrance of the taxiway 2 into the notch 6 that intersects with the taxiway, and then rapidly pushed down. Then, the bag opening B rotates the row 3t3 from the position shown in FIG. 3 to the position shown in FIG. 4. In this process, the adhesive tape 11 is pulled out from the reel 27 and closes the opening between the pocket 5@ and the notch 6 between the pocket 4 and ◎ containing the bag opening B. At the same time, the bag opening B is moved to the operating lever 1.
3, the operating lever 13 rotates counterclockwise around the pivot shaft 19 from the position indicated by the two-dot chain line to the position indicated by the one-dot chain line, as shown in FIG. The activated links 20, 21 advance the actuating block 7 horizontally along the guide member 16 against the force of the spring 17. In the process of horizontal movement of the operating block 7, when the cutter 9, which is horizontally protruded from the tip of the head 10, enters the pocket, it is pressed against the tape presser claw 12 via the spring 18. The tape 11 is then pressed against the tape holding claw 4 formed at the edge of the opening of the pocket (see FIG. 4). When the head 10 enters the pocket@, the adhesive tape 11 is cut by the cutter 9 as shown in FIG.

As is clear from FIG. 4, before the adhesive tape is cut, the opening of the pocket@ is closed and the adhesive tape is accurately attached to the circumferential surface of the rotor 3, so that the cut length of the tape is constant. When the head 10 has entered the pocket@, the cut end of the adhesive tape is held between the edge of the head 10 and the tape holding claw 4, as shown in FIG. Next, spring 1
In the process of returning the actuating block 7 to the position shown in FIG. The head 10 is pulled out of the pocket@ as shown in FIG. When the tape presser pawl 12 and the tape press against the spring 18 and the operating block 7 returns, the spring 18 rebounds and bends the ends 30 and 31 of the tape into a loop as shown in FIG. Press it against the tape holding claw 4 of the pocket@. In FIG. 9, the bent end 30 formed at the upper edge of the opening of the pocket ◎ remains as one end of the tape for closing the bag opening next time. As is clear from FIG. 9, when the adhesive tape 11 closing the opening of the pocket ◎ is cut and the end thereof is bent, the bag opening B is located between the pocket 4 and the ◎. A cutout 6 is freely located in a space that intersects with the guideway 2, and the opening of the cutout 6 is cut into a certain length and attached to an adhesive tape C with both ends bent. It is obstructed.

Next, when the bag mouth part B is further pushed down, the adhesive tape C is peeled off from the rotor 3 and wraps around the bag mouth part B in its center, and as it pushes open the adhesive tape compression spring 14 and passes through it, it is peeled off from both sides. The bent ends 30, 3 are elastically pressed.
The adhesive surfaces of the parts other than 1 are firmly adhered, and the bag opening B is completely closed, and the bag is pulled out laterally through the extraction hole 25. FIG. 10 shows the state in which the terminal is opened in a butterfly shape after the bag opening has been closed. As can be understood from the above explanation, when the bag sealer tape end processing device of the present invention is used, the adhesive tape can be cut to a certain length, and the opening of the bag can be closed as shown in FIG. Both ends of the adhesive tape can be quickly bent across the longitudinal direction of each end tape so that the adhesive surfaces do not adhere to each other.
