Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to a bundling device that is installed in, for example, an automatic mail processing device and that bundles stacked mail.

(Prior Art) In general, this type of bundling device is equipped with a tape feeding mechanism at the top and bottom of a conveyance path for conveying mail items in a stacked state, and from these feeding mechanisms, a tape is transferred according to the size of the mail items. After the tape is sent out, it is first bundled horizontally and its ends are glued by spraying hot melt, and then the tape is turned horizontally by 90 degrees using a direction changing section and bundled vertically to form a criss-cross shape.

(Problem that the invention aims to solve) However, in the past, the amount of tape fed from the upper and lower feeding mechanisms was not regulated, and the amount of tape fed changed depending on the amount of stacked mail items, causing heat generation. The position of the seal part varies.

For this reason, as shown in FIG. 1a, the sealed portion 2 of the tape 1 may be under the mail A, and when hot melt is sprayed onto this sealed portion 2, the hot melt adheres to the floor of the direction changing section. Also,
If the seal part 2 hits the guide of the direction changing part and the mail A skews, hot melt will adhere to the floor in the same way. In this way, when the hot melt adheres to the floor, the next bundle of mail A that enters the direction changing section is caused by this hot melt, so that the hot melt adheres to the floor.
The tape 1 is rotated as shown in FIG. 1, and the bottom mail item A is later pulled out as shown in FIG. If the tape 1 is turned around, it will overlap the paper bill, which will have a negative effect on the next barcode reading, and if the mail item A is pulled out, the heat seal part of the vertical bundle will be damaged. There was a drawback that the mail A was caught in the seal part 2, resulting in failure to separate the seal part 2.

This invention was made with attention to the above circumstances,
The object thereof is to provide a bundling device in which the position of the seal portion of the tape does not vary and change even if the amount of stacked objects to be bundled changes.

[Structure of the idea]

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention aims to move the objects to be bundled from a pair of feeding mechanisms disposed above and below via a movement path for relatively moving the objects to be bundled. In a device that sends a tape according to the size of the object to be bundled and binds the tape by gluing its ends, the upper and lower feeding mechanisms include a plurality of feeding rollers that span the tape, and a plurality of feeding rollers that bridge the tape, and An adjustment roller that bridges the tape located between the rollers,
a guide body for movably guiding the adjustment roller along the tape feeding direction; a driving means for moving the adjustment roller by selectively driving the plurality of feed rollers; The present invention is characterized in that the feeding mechanism includes a stopper which is provided on the feeding mechanism and abuts the adjustment roller to regulate the amount of movement thereof, thereby regulating the feeding amount of the tape to a constant amount.

(Function) By regulating the amount of tape fed out from the lower feeding mechanism to a constant amount, the position of the seal portion of the tape can be made constant regardless of the stacked amount of objects to be bundled.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 2 to 6. FIG. 2 shows a bundling device, in which reference numeral 11 is an upper feeding mechanism provided on the upper side of the conveyance path 12 for postal items A to be bundled; This is a lower side feeding mechanism provided on the lower side. The upper feeding mechanism 13 is conventionally known and has a supply roll 14 from which the tape 15 is fed. This tape 15 is connected to a guide roller 16 and a feed roller 17.
It spans the adjustment roller 22 and the step roller 18 which are movable via the feed roller 19.
and is introduced into the sealer section 21 over a guide roller 20.

Further, a micro switch 26 is provided at one end of the guide plate 24, and the micro switch 26 is turned on and off by the adjusting roller 22.

Before the start of operation, the micro switch 26 is pressed by the adjustment roller 22, and when a command to start operation is received, the drive device 28 causes only the feed roller 19 to rotate for a predetermined time while the feed roller 17 is stopped. It is becoming more and more common. After the feed roller 19 stops rotating,
This time, the drive device 28 rotates the feed roller 17, which feeds the tape 15, moves the adjustment roller 22 downward, and moves the micro switch 2.
Turn on 6. When the micro switch 26 is turned on, the rotation of the feed roller 17 is stopped.

On the other hand, the lower feeding mechanism 13 is constructed in the same manner as the upper feeding mechanism 11 described above, but the lower feeding mechanism 13 has a mechanism for regulating the feeding amount of the tape 15 as shown in FIG. A stopper 23 is provided. This stopper 23 is provided approximately in the center between a pair of guide plates 24, 24 which are spaced apart from each other, and is brought into contact with an adjustment roller 27 to regulate the amount of movement thereof to, for example, 120 mm, thereby controlling the feed amount of the tape 15 to 120 mm.
It is now being quantified in mm. The movement of the adjustment roller 22 is guided by a guide hole 25 formed in the guide plate 24 along its longitudinal direction.

Further, a micro switch 26 is provided at one end of the guide plate 24, and this micro switch 26 is turned on and off by the adjustment roller 27.

The micro switch 26 is pressed by the adjustment roller 27 before the start of operation, and upon receiving a command to start operation, the drive device 28 causes only the feed roller 19 to rotate for a predetermined time while the feed roller 17 is stopped. It is becoming more and more common. After the feed roller 19 stops rotating,
This time, the drive device 28 rotates the feed roller 17, thereby feeding out the tape 15, moving the adjustment roller 27 downward, and turning on the micro switch 26. When the micro switch 26 is turned on, the rotation of the feed roller 17 is stopped.

Next, a method for bundling the mail A will be explained.

First, the tape 15 of the upper feeding mechanism 11 and the tape 15 of the lower feeding mechanism 13 are heat-sealed when the previous mail item is bundled, as shown in FIG. It exists in the front like a curtain.

Therefore, as shown in Figure 6b, mail A is
When trying to pass between the sealer parts 21, 21,
The upper and lower tapes 15, 15 are fed out by the rotation of the upper and lower feed rollers 19, 19, respectively. Then, when the mail A passes between the sealer parts 21 and 21 as shown in FIG.
is only sent out in a certain amount. That is, when the lower tape 15 is fed out by the rotation of the feed roller 19 on the lower side, since the tape 15 is fixed by the feed roller 17 which is in a stopped state, the adjustment roller 27 is lifted and moved 120 mm in the direction of the arrow. Since the lower tape 15b comes into contact with the stopper 23 and stops, the lower tape 15b is fed out by a fixed amount of 120 mm.

After the upper and lower tapes 15 are wrapped around the mail A in this way, the upper sealer part 21 is lowered to heat-weld the upper and lower tapes 15, 15, as shown in FIG. 6d. At the same time, the sealer part 21
The tapes 15, 15 are cut by a cutter (not shown) built in, and the state shown in FIG. 6a is returned again.

As mentioned above, the adjustment roller 27 is moved to the stopper 2.
In order to quantify the feeding amount of the tape 15 to 120 mm by contacting the tape 15 with the tape 15, if the width of the mail piece A is, for example, 120 mm, the position of the heat seal part 15a is as shown in Figure 3 a.
It becomes constant at the position shown in .

Incidentally, when the width of the mail item A is, for example, 90 mm, the position of the heat seal portion 15a is fixed at the position shown in FIG. 3b.

(Effects of the invention) As explained above, according to the invention, the amount of tape sent out from the feeding mechanism on the lower side of the moving path is regulated to a constant amount, so unlike the conventional method, the amount of tape to be bundled is The tape feed rate does not change, and the position of the heat seal part can be kept constant. Therefore, it is possible to prevent the heat-sealed portion from wrapping around the top and bottom of the objects to be bundled, and it is possible to maintain a good barcode reading rate, as well as to avoid failure in separating the heat-sealed portion in vertical bundles. This has the effect that there is no such thing.
