Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to a bundling device for packaged products, and more specifically, the present invention relates to a device for bundling packaged products, and more specifically, the present invention relates to a device for bundling packaged products. The present invention relates to a bundling device for packaged items that can automatically bundle the packaged items in an optimal bundled state according to their height, etc., without breaking the packaged items.

<<Prior Art>> Conventionally, packaged items such as postal letters are sorted by postal code using a postal letter automatic sorting device, etc., and are automatically stacked into arbitrary numbers of addresses. Because the bundling work was done manually using strings, etc., the work efficiency was poor and was a hindrance to automation.

In other words, unlike the packaging of food, pharmaceuticals, and other items, the work of bundling postal letters must be sorted by postal code and then bundled. However, since the number of items to be grouped and accumulated, that is, the size of the items to be packaged, varies from time to time, it is not possible to determine the conditions for packaging them in bags with fixed dimensions. In addition, regarding the accumulation status of packaged items, in cases where only postcards are accumulated, it is relatively stable, but in the case of sealed letters, the amount of letters stored, the storage condition (folding method), etc. Therefore, each form is different, and in reality, postcards and envelopes are accumulated as a mixture, and the amount and form of accumulation varies from region to region. It has the characteristic of being easily broken down. In addition, since the packaged item is light in weight, it has the disadvantage that it is lifted backward by the tension of the tape during the taping stage.

On the other hand, Utility Model Publication No. 55-39777 was published as an automatic binding machine that automatically adjusts the pullback length of the tightening band according to the height of items to be bundled (packaged items) of different heights flowing randomly. The gazette is publicly known.

However, in this known technique, the clamping force is adjusted in stages according to the height of the packaged items, so there is a problem that the clamping force cannot be adjusted sufficiently. Problems similar to those of the above-mentioned conventional techniques have not been solved, such as the possibility that the tape may collapse and the packaged item may be lifted backwards by the tension of the tape during the taping stage.

≪Problems to be solved by the invention≫ The present invention has been made in view of the above-mentioned problems, and its purpose is to automatically It adjusts the clamping force steplessly to clamp the packaged items with the optimal clamping force, and automatically secures the packaged items using tape, etc. without disrupting the stacking condition of the packaged items.

Since D' is the same as that explained in the first binding device, the explanation will be omitted.

≪Function≫ Next, to explain the function, the packaged product W is a state in which postal letters such as sealed letters and postcards are accumulated to any number of addresses.
When it is supplied to the transfer device A as
As a result, the packaged item W is supported at two predetermined positions on the rear side and moves forward to a predetermined pitch. At this time, since the transfer device A is formed to be tilted upward in the transport direction of the packaged product W, the packaged product W comes into contact with the rear side in the traveling direction, that is, with the transport claws 3, and is aligned. Further, the paper bill X is appropriately placed at a predetermined position on the uppermost surface of the packaged product W while the conveying claws 3, 3 are stopped, and thereafter moves forward together with the packaged product W.
Then, when the tape seal part is reached, the air cylinder 27 in the packaged product restraining device B, which operates in synchronization with the movement of the transport claws 3, 3, is activated, and the packaged product restraining member 33 is lowered to lower the packaged product. The upper surface of W is held down as shown in FIG. 12, and in this state, the forward/reverse motor 19 is operated, and the pinion gear 20 and the rack 24 engage to move in synchronization with the movement of the packaged product W. Then, when it has moved a predetermined amount, it is stopped by an appropriate instruction from a detection means (for example, a micro switch or the like). Since the binding tapes 34 and 35 are integrally sealed and hang down in the path of the packaged product W, they are engaged with and pulled by the packaged product W as the packaged product W moves forward. It will look like Figure 13. The tension rollers 38, 39 of the tapes 34, 35 move upwardly to the right in the figure within the guide members 40, 40, 41, 41 by the amount that the tapes 34, 35 are pulled out. At this time, the packaged product W is transported by the transport claws 3,
3, the binding tapes 34 and 35 can be moved forward while being reliably pulled out. Since the upper part of the packaged product W is suppressed by the packaged product restraining member 33, there is no fear that the front side of the packaged product W will be lifted up by the repulsive force of the binding tapes 34, 35, and the packaged product W can be securely and neatly grasped. can be bundled.

In this state, the air cylinder in the tape seal device C operates, and the upper and lower sealers 48 and 49 collide as shown in FIG. 14, and the seal heads 52 and 53
As a result, the binding tapes 34 and 35 are sealed together, and at the same time, the air cylinder 50 is actuated to lower the cutter 51 and cut the sealed portion. Next, the feed rollers 36 and 37 rotate, and the tension rollers 38 and 39 descend to the lower left in the figure as the tape is fed out by the operation of the feed rollers 36 and 37, and then stop when reaching the initial state. Although not shown, the feed rollers 36 and 37 are started and stopped using well-known electrical commands.

If only the primary bundle is enough to bundle the packaged items W, at this time, the paper bill sealing device D applies pressure from above the bundle tape 34 with a well-known heat seal bar, The tape 34 and the paper bill X are heat-sealed together as shown in FIG. 15, and the pressing member is actuated in response to a command to press and transfer the package in the lateral direction, allowing it to fall from the chute and be discharged to a predetermined position.

Further, in the case of packaged items that require cross-bundling, the following actions are further performed.

The primary bundled products W' to be packaged further advance, and just before the secondary bundle, hot melt 56 is dotted at a predetermined position on the primarily bundled tape 35 as shown in FIG. Then, it reaches the secondary bundle section. In the second bundling device 57, tape is hung in a direction perpendicular to the tapes that have been primarily bundled, and the article to be packaged W' is held down by a member that holds the upper part down as in the case of the primary bundle. 62, and the rear side is pushed by the pusher 61 to move forward.

The upper and lower binding tapes are pulled out while being engaged with the front side of the packaged item W', and are sealed and cut at the rear side of the packaged item W' as in the case of the primary binding tape, and then the paper is attached from the top side. Pressure is applied by the seal bar of the bill sealing device, and the cross-bound upper tape and paper bill are thermally bonded together as shown in FIG. 17.

<<Effects>> As described above, the present invention includes a transport means for transporting a packaged product pushing member for sequentially transporting the packaged products, and a transport means for transporting the packaged products by intersecting with the transport path for the packaged products in this transfer means. A tape wrapping means is provided that stretches the binding tape in a direction that blocks the transfer of the items and engages and pulls out the tape as the item passes through, so that the tape is secured to the item being packaged. It is pulled out along the shape of the item. In other words, the tape is pulled out by the optimal amount according to the shape of the packaged item, especially its height, etc., and the optimal holding force is automatically achieved for the packaged item whose height etc. change randomly. But it can be held together. Moreover, since the packaged article restraining means is provided so as to move in synchronization with the progress of the packaged articles while restraining the packaged articles at least when the tape is pulled out from the tape wrapping means, the tape is not easily wrapped when the tape is wound. The packaged items do not float due to the tension of the tape, and tape sealing can be performed reliably and tape can be applied with a strong binding force.

Furthermore, since the transfer means is constructed so that the packaged items are transferred while tilting upward in the transfer direction, the packaged items move forward while always receiving the effect of descending toward the transfer claw located at the rear side. This has the effect of not only positioning being performed but also preventing the load from collapsing due to shocks during starting and stopping during intermittent transfer.

Furthermore, if a paper bill with classification information such as a postal code printed on it is heat-sealed together with the bundling tape, the packaged items after bundling are automatically scanned by a barcode reader etc. during the subsequent transportation process. Various effects can be achieved, such as making it easier to read and classify destinations, and making it possible to group the packaged items into categories for delivery areas using a consistent line.

On the other hand, in the second invention of the present application, the packaged items are taped in a cross pattern, and the tapes are bonded together by hot melting or the like, so that the effect of the first invention is achieved. In addition to the effect,
Furthermore, it is possible to automatically bundle the packaged items such as postal letters without the tape coming off due to the load during handling of the packaged items after bundling.

Note that when the paper sheets are relatively uniform in size, they may be placed horizontally, and the operating mechanism of each part shown in the above embodiments may be modified in various ways without departing from the gist of the present invention. It is something.
