Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a sheet packaging device for heat seaming/I/ing various products.

[Background technology]

BACKGROUND OF THE INVENTION Conventionally, a sheet packing apparatus has been used to pack building materials and various other works by placing two sheets over the top and bottom of the work and heat-sealing both side edges and the rear edge thereof.

However, it is difficult to pack the workpieces one by one while conveying them on a conveyor. Derou.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a sheet packing device that can pack workpieces with different width dimensions, and in the case of small width workpieces, can pack two workpieces at the same time, thereby increasing efficiency.

[Disclosure of the invention]

The sheet packaging device of the present invention is a vertical sealing device J! that heats and welds the upper and lower sheet metals of the work along the longitudinal direction. t
t-, standby moving device that is placed at three locations in the width direction of the conveyor, at both ends and in the middle, and lifts and lowers the middle longitudinal device to the standby position. It was established.

According to this configuration, in the case of a work with a large width dimension, the middle longitudinal sealing device is kept on standby, and only the longitudinal sealing devices on both sides are used. In the case of small-width workpieces, two workpieces are conveyed side by side in the width direction, and the upper and lower sheets are sealed between the two workpieces by an intermediate vertical sealing device.

Examples Examples of Iksho koji according to the present invention are shown in Figures 1 to 8g8. In the figure, 1 is a carry-in conveyor, carry-out conveyors 2 are arranged in a column with an interval between them, and a width direction sealing device 3 and a vertical direction sealing device 4 to 6 are installed in order between them. Finally, a sheet feeding device 7 is installed on the upper side of the width direction sealing device 3. Input conveyor 1 is two divided conveyors IA.

It is divided into IBs in the width direction. The carry-out conveyor 2 is arranged in a row of small conveyors 28i-2, and a cross conveyor 8 that changes the conveyance direction to a right angle direction is installed in the small conveyor 23flJ11 so that it can float and sink.

! '-) The feeding device fit 7 is the upper and lower sheet rolls 9'.

From 10', a sheet 9.10 is fed above and below the workpiece M. The sheets 9 and 10 are made of vinyl film or the like. Seat row A/9', 10'id XN
It is held on the rotation scale at low/l/12. The width direction sealing device 3 is attached to the upper and lower heating blades 13't and the lowering cylinder 14 extending in the width direction of the carry-in conveyor 1, and is moved up and down in opposition to each other. The heating blade 13 is capable of welding and fusing, and is equipped with an electric heater and the like. The vertical seal lv devices 4 to 6 are arranged at three locations at both ends in the width direction of the carry-in conveyor 1 and at the center. These longitudinal sealing devices 4 to 6 are sandwiched between a pair of heating belts 16 suspended between rollers 15. The heated TV 16 is heated by hot air from an attached hot air blowing nozzle Iv17. Center longitudinal sea) V mounting W
Reference numeral 15 indicates that the upper and lower heating plates 16 are raised and lowered by an outer cylinder 18 to a standby position where they do not interfere with the workpiece M.

As the moving workpiece M, the wider workpiece M shown in Fig. 7 is used.
Consider the case where a narrow workpiece M2 as shown in FIG. 8 is packed. Work M in FIG. 7 is a framework, and work M2 in FIG. 8 is a decorative eaves cover.

The case of a wide work M machining will be explained. in this case,
Center vertical sea/V device 51r: Standby vertically. When the workpiece M is carried into the carry-in conveyor 1 according to the arrangement shown in Fig. 3, the upper and lower sheets (9.10) were welded to each other at the tips of the arrangement shown in Fig. 2 during the previous packing and are in the following state. . The workpiece λ(,) is conveyed by the carry-in conveyor 1 and enters the sheath) 9.10, and the upper and lower sheaths) 9.10 cover the top and bottom of the workpiece M as they are conveyed. Then, along with the conveyance, the upper and lower seams) 9.10 are
They are welded together by L/device 4.6 (FIG. 4). When the rear end of the workpiece Δ(, passes through the widthwise sealing device 3, the upper and lower sheets 9°10
is welded along the trailing edge of the workpiece M, and is fused back and forth at the welded part. In this way, the sheets 1-9 and 10 are placed in a molten state on the four sides of the workpiece M, and the packaging is completed. The packed workpiece M is conveyed by an unloading conveyor 2 and then transported laterally by a cross conveyor 8.

In the case of narrow workpieces M2, two pieces are carried side by side onto the carry-in conveyor 1 as shown in FIG. In this case, the central longitudinal sealing device 5 is placed in the operating position. Kon
Therefore, as shown in Fig. 6, the upper and lower sheets 9°10 that overlap the two workpieces M2 have vertical seams/V at both ends.
At the same time that the side edges are welded in device 4.6, a central longitudinal seam device 5 is also welded between the two workpieces M2. The rest is the same as in the case of the wide work M1. Note that the central vertical sea/l/device 5 may be one that can be melted down simultaneously with one capacity person.

In this way, even with the wide workpiece M machining, the narrow workpiece M2
In the case of narrow workpieces M2, two pieces can be packed at the same time, resulting in high efficiency.

In the example 1rII, a 71D thermal belt 16 is used for each longitudinal sear I unit 4 to 6', and the length is as follows:
For example, a pair of heating rollers may be used. Further, the central vertical sealing device 5 may have two melting layer means arranged in the width direction so that the upper and lower seams (9 and 10) are melt-rinsed with two bath shield lines.

FIG. 9 shows a working fin using this sheet packing device. In the same figure, numeral 20 is the packing fluid stop, and 20 is the location where the seal/L/device is placed. From the cross conveyor 8 for packing and loading, each conveyor 21 is connected to the carry-in conveyor 1.
A loading place 25 for packed workpieces is provided at the end of the conveyor 2, which is installed parallel to the arrangement of the carry-out conveyors 2. 2
6 is the location where the unpacked workpiece Δ() is placed. By using this stiff fin, the packing can be carried out by one worker.

〔Effect of the invention〕

The sheet packing apparatus of the present invention has five advantages: it can pack workpieces with different width dimensions, and in the case of small width workpieces, it can pack two pieces at the same time, improving efficiency.
