Description

[Detailed Description of the Invention] The present invention relates to a banding device for hanging a packing band on an object to be packed in a cross, square or square shape (hereinafter referred to as orthogonal hanging).

(Prior art) As shown in Fig. 1, for the object to be packed a,
When band b is hung orthogonally, two packing machines are generally installed on the line as shown in FIG.

This equipment requires multiple packaging machines, which increases equipment costs and generates a lot of noise.Furthermore, it is necessary to incorporate a turntable, etc., into the conveyor line between the packaging machines to change the banding direction by 90 degrees. Therefore, the device becomes large.

To improve this drawback, Japanese Patent Publication No. 55-46928 has been proposed, but this device uses a primary hanging band to lift the device onto the packaging machine, rotate it 90 degrees, place it on the packaging machine again, and then double the device. This method requires a second hanging, which not only makes the lifting device and rotation device extremely complicated, but also has essential drawbacks such as not being applicable to heavy objects, making it impractical.

(Problem to be solved) The purpose of this project is to save space by reducing the number of packing machines required to one, reduce noise by eliminating the turntable in the roller conveyor line, and also reduce the noise when packing heavy items. To provide an automatic packing device capable of performing orthogonal banding without requiring any changes.

(Solution) In this case, a rail for guiding a self-propelled cart and a U-shaped band guide arch are fixedly installed on one side of the rail between two receiving/unloading platforms, and the self-propelled cart is height-adjustable. A sealer comprising a turntable and its turning device, having a U-shaped band guide arch connected oppositely to the end face of the U-shaped fixed band guide arch, and in contact with one side of the object to be packaged on the turntable. A packing machine equipped with a packing unit is placed on a moving rail disposed on the other side of the self-propelled cart guide rail at right angles to the guide rail, and one packing machine can carry out orthogonal loading. In addition, it can be applied to large-weight items.

Of course, in the turntable according to the present invention, insertion grooves into which the lower band guide arch on the packaging machine side is inserted are provided orthogonally when packaging other than pallet packaging.

(Example) 1 and 2 are receiving/unloading tables, 3 is a guide rail arranged between them, and 4 is a self-propelled cart.

The self-propelled trolley is connected to a support plate 17 on a pedestal 5 that can be raised and lowered by a lifting rod 10 of a hydraulic cylinder 9, and a rotating shaft 14 that passes through the support plate and is fitted to the outer periphery of the lifting rod. Turntable 6 and rotation axis 90°
It is equipped with a rotating turning device 11 and is self-propelled by wheels 8 driven by a motor 7.

That is, the support plate 17 is the cylindrical body 1 vertically disposed on the pedestal 5.
6 and a guide pin 18 provided on the lower surface of the support plate to fit therewith.
5 and is provided with a turning device consisting of a rack 12 driven by a cylinder (not shown) on the lower surface of the support plate, and a sector gear 13 that meshes with the rack and is pivoted on a rotation shaft 14.

The turntable 6 is a circular or square plate body, and the upper surface thereof is provided with band guide insertion grooves 19 and 20 that intersect at the center, and the center of the lower surface of the plate body is supported by an elevating rod 10. It is connected to the rotating shaft 14 that is fitted therein.

21 is a U-shaped band guide arch 23c, 23
d, and is movably installed or fixed on one side of the guide rail 3.

23c is the vertical part of the arch, and 23d is the upper side, which is located above the center of the turntable in the packed state.

Reference numeral 22 denotes a mobile packing machine, which includes U-shaped band guide arches 23a and 23b, and a sealer unit 2.
6 built-in, and moves on a moving rail 27 laid on the other side of the guide rail 3 at right angles to the guide rail.

This movement connects the ends 24, 25 of the arches 23a, 23b to the ends of the arches 23c, 23d, respectively.

28 is a motor for moving the packing machine, and 29 is a wheel.

In addition, as shown in FIG. 3, in order to reduce the moving distance of the packing machine, a U-shaped band guide arch 23a,
23b may be divided, and only 23b may be connected to a rod 30 that moves forward and backward along the moving rail 27, and this may be moved forward and backward by the motor 33 and drive roller 34. (Special Publication No. 52-2358) 31 and 32 are guide rollers.

(Operation Description) The operation of the present device will be described below in a case where pallet packaging is not used, that is, in a case where a band guide arch insertion groove is provided on the turntable and a criss-cross arrangement is performed.

Before the start of operation, the packing machine 22 and the U-shaped band guide arches 23a, 23b are retracted, so that the self-propelled cart 4 can freely run on the guide rail 3.

In this state, when the object A to be packed is placed on either the receiving/unloading table 1 or 2, the self-propelled cart 4 moves directly below it and then activates the cylinder 9 to place the object A on the turntable 6. The object is supported and moved to the position of the fixed band arches 23c and 23d.

The packing machine 22 moves forward and causes the lower arch 23b to enter the insertion groove 19 of the turntable 6, that is, directly below the object A to be packed.

After the band B is arranged along the guide arch by a feed roller (not shown), it is tightened and wrapped around the periphery of the object to be packaged, and then the band is welded and cut.

When the packing machine 22 and the lower arch 23b retract, the turning device 11 of the self-propelled cart is activated to turn the turntable 6 by 90 degrees.

In this case, if the item A to be packed is large,
It performs a turning operation at the position indicated by the two-dot chain line in FIG. 4 and returns to the predetermined position again.

Once again, after the packing machine moves forward and the lower arch enters, band placement, tightening, welding, and cutting are performed, and the packing machine 22 is retracted to return to the starting state.

The self-propelled cart 4 travels to a desired receiving/unloading platform, lowers the turntable 6, and places the package on the platform to complete the work.

In actual equipment, all of the above operations are performed by sequence control.

In addition, in the case of a square hook, the insertion groove of the turntable is provided corresponding to the desired band rotation position.

(Effects) In this case, the self-propelled cart that delivers and supports the packed items during work is equipped with a lifting cylinder 9, so the vertical positional relationship between the receiving/unloading platform and the lower arch of the packing machine has been changed. You can also respond freely.

Furthermore, since the self-propelled cart is equipped with a turning device, it can turn anywhere on the guide rail, resulting in low noise and space savings.

It also has the advantage of being able to handle even heavy items to be packed.
