Description

[Detailed Description of the Invention] The present invention relates to an improvement of a packaging machine, particularly a semi-automatic so-called horizontal packaging machine.

Figure 1 shows a typical conventional semi-automatic horizontal packaging machine of this type. 1 is the packaging machine body, which houses the unit 2 that performs various mechanisms such as band supply, tightening, and gluing necessary for packaging. A band reel 3 is rotatably supported and mounted on the main body 1, a work table 4 is arranged on a base 5 near the unit part, and a side plate 6 of the main body 1 can be opened and closed with a hinge or the like. In addition to mounting, casters are provided at appropriate positions on the bottom of the base 5.

In these conventional semi-automatic horizontal packaging machines, since the band reel 3 is located at the head of the main body, it requires physical strength to replace the band, and the box-shaped main body 1 installed on a rectangular base can be moved directly to the work place. In order to place and use it, the operator must stand on the side of the main body 1 and insert the tip of the band B into the band insertion guide path 8 provided near the unit 3 part 2 in the center of the front panel 7 of the main body. , I was forced to work in an unnatural posture where I was constantly stretched out.

In addition, inspection of the band set and internal mechanism to start packing cannot be done smoothly because the side plate 6 is opened and the unit part 2 is inspected from the side, making these operations complicated and requiring cleaning of the work area. However, it had various drawbacks, such as the need to be careful not to leak the main body.

The present invention aims to eliminate the drawbacks of these conventional products and provide a semi-automatic horizontal packaging machine that is compact and has high working efficiency.The details thereof will be explained below based on drawings showing embodiments.

In FIG. 2, reference numeral 10 denotes a packing machine main body.The bottom of the main body is fixedly supported on a box-shaped support 12 fixed to an X-shaped leg 11, which has a shape that does not get in the way of work, and the unit 1 is mounted on a side plate of the main body 10. The front plate 13 facing the ~ section has a notch 14 in the central longitudinal direction that exposes a band guide flap, which will be described later, and further has a work table 15, which will be described later, with an appropriate length in the longitudinal direction on both left and right sides of the front plate 14. Groove 16 for inserting
．． 16 and the groove 1 on the back side of the front plate 13.
6. As shown in FIGS. 5A and 5B, the rack-shaped engaging member 24 is fixed along the line 6.16.

On the other hand, a locking member 25 made of a bolt or the like is attached to the insertion piece 15' that slightly protrudes upward from the end portions of both side plates of the work table 15, and the locking member 25 is engaged with the engagement member 24. Adjust and fix the position (height) of the
As shown in FIG.
After raising and lowering the locking member 25, the engaging member 2
4 by engaging the work table 1 at any position.
The height of the table 5 can be adjusted and fixed, and the front plate can be opened and closed while the work table is fixed.

Therefore, the above-mentioned unit part may be provided so that it faces the notch 14 between the upper part of the work table 15 and the head of the main body at the lowest end position with respect to the front plate 13 of the work table 15. When it is impossible to install in close proximity, and when small objects are to be packed,
The unit part is installed below the point that bisects the distance between the main body head and the lowermost end of the worktable and above the lowermost end of the worktable.

Further, a substantially triangular band reel guard 18 is provided on the back plate of the main body 10, and a circular band reel 19 is removably mounted with a nut bundle inside the band reel guard.

Reference numeral 20 denotes a 1-rule guide roller which is twisted when the band is unwound from the reel 19 to prevent vertical cracking of the band, and this may be provided at an appropriate position within the main body.

In FIG. 2, reference numeral 17 denotes a band guide groove, which is located at the center of the work table 15 and on the same plane as the longitudinal direction of the notch 14 of the front plate 13.

Further, 21 is a caster provided on the leg, and 23 is a roller on the work table.

FIGS. 3 and 4 show a band guide flap 30, which includes a flap 31.3.
1 facing the notch 14 in the longitudinal direction, and a band guide flap on the drive roller 38 side (described later) in the band insertion opening 22 provided in the notch 14 located at the edge of the head of the main body, and a flap 31 in the unit part. They are arranged so that the edges of 31 are facing each other.

This band guide flap 30 also has a bracket 34.34 fixed to the side of the flap 31.31 which is biased closed via a spring or the like, and the bracket 34.
．． Idle roller 36 which is removed from the bearing etc. by 34
, 36, and a cutout 35.35 is provided in the upper part of the flap 31.31 to support the idler roller 36.3.
6 faces inside the flap, and a notch 37 provided in the bandway 32 allows a drive roller 38 provided on a shaft having a bueno 40 interlocked with a drive mechanism with a belt or the like to come into sliding contact with the idle roller 36.36. do.

When using the packing machine of the present invention, a certain amount of band is drawn out using a timer or the like, and the band is manually wound around the object to be packed. When the tip of the band is inserted into the band insertion slot 22, the rotating drive roller 38 and the idle roller Band B is held between 36 and 36, so that the band instantly reaches the unit installed in the main body, a known limit switch is activated, a band tightening mechanism is activated, and the band is tightened at the same time. 31. 31 is pushed open, completely wrapped and tightened around the object to be packed, and then band cutting and welding steps are performed to complete one packing.

Since the present invention is constructed as described above, it is possible to provide a packaging machine that has a small main body, is compact as a whole, and is lightweight.

In addition, during packing work, the worker's feet enter the bottom of the main unit and work in close contact with the main unit, and the height of the support can be changed as appropriate, or if it is made telescopic, the height of the unit itself can be changed. It can be used on any packaging line, and the height of the work table can be changed, making it possible to work without worrying about the size of the items to be packed. Since the main body is supported by a holder, it will not affect the main body even if the work place is humid or unclean, and the work place can be easily cleaned.Furthermore, the front plate of the main body can be opened and closed, so it can be used for band sets, etc. ,
Inspection and repair of the internal mechanism is easy, and the band reel guard is bundled, making it suitable for transporting the main body.
Furthermore, since the band reel is provided at a low position, it has various excellent practical effects such as extremely easy band replacement.
