Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an automatic packing device for packing and binding a bundle of newspapers, magazines or the like.

(Prior Art) For example, when shipping newspapers, stacking a predetermined number of copies into one bundle, stacking a plurality of these bundles to form one packaging target, and protecting each packaging target Addressing work of laying out paper and attaching a delivery slip with the address printed according to the shipping destination, packing work that covers the packaging object with protective paper and a delivery slip, and packing letters on the outer surface of the packaging film It is then packaged after the banding work is performed.

The above-mentioned series of operations are each performed by an automatic machine, and an apparatus for automatically packaging a packing target is, for example, Japanese Patent Publication No.
Japanese Patent Laid-Open No. 572 discloses a compression wrapping apparatus, and a binding machine for banding is disclosed in, for example, JP-A-63-11.
It is well known from the publication.

The binding machine has a gate-shaped arch on the table, the packing object is placed on the table in a state orthogonal to the arch, the free end of the binding band is circulated along the arch, and then the tightening is performed. The band ends are attached and cut to automatically bind the objects to be packed. When performing cross-shaped binding, for example, two binding machines are arranged adjacent to each other, primary binding is performed on one side, then the binding target is rotated 90 degrees on the turntable, and then the other binding machine is moved. Send them in for secondary binding. Alternatively, a conveyor device may be used instead of the turntable, and the transport directions of the objects to be packed may intersect at a right angle during the primary binding and the secondary binding.

(Problems to be solved by the invention) However, in the above-mentioned conventional device, a turntable and a conveyor device for changing the conveying direction are indispensable for performing the cross-shaped bundling, and the whole device becomes large accordingly. The required installation area was large.

When the cross-shaped binding is performed, banding parallel to the long side portion of the packing target is performed by the primary binding, and then banding parallel to the short side portion of the packing target is performed by the secondary binding. This is to prevent the former band from being largely bent and disengaged at the time of handling a load by tightly binding the band that is primary bound with the band that is secondary bound.

As described above, in the conventional binding machine, the transfer direction of the object to be packed is specified to pass through the gate-shaped arch. Therefore, at the time of primary bundling in which banding is performed in parallel with the long side portion of the packing target, it is necessary to feed the packing target with the short side portion thereof parallel to the transfer direction. That is, FIG.
As shown in (a), in the case of a packaging object M in which a plurality of newspaper bundles m are stacked one above the other, the newspaper bundles m are transported in a horizontally long position with the folded curved surfaces in front and back.

In such a transfer mode, the newspaper bundle m shifts back and forth due to inertial force, or the upper newspaper bundle m shifts down due to inertial force when transferring from one processing device to the next processing device or when waiting and stopping etc. Therefore, it is necessary to suppress the feeding speed of the object M to be packed to a certain speed or less. Further, in each processing step before the completion of the primary binding, it is necessary to individually correct the posture of the transferred packaging object, and there is a limit in improving the processing efficiency of the packaging work as a whole.

This invention solves the above-mentioned problems, and by improving the binding machine, it is possible to bind cross-shaped objects to be packed without using a turntable or a conveyor device for changing the conveying direction. The purpose is to simplify the structure of the device, reduce the installation area, and reduce the equipment cost.

Another object of the present invention is to make it possible to consistently transfer and package the object to be packed in a vertically long posture that does not easily collapse the load, improve the feeding speed, and omit the correction of the posture in each processing step. , To improve the efficiency of packing work as a whole.

(Means for Solving the Problem) The present invention is directed to a stacking device that stacks a predetermined number of newspapers, magazines, etc., to form a single packing target, and a packing target that compresses the packing target in the stacking direction and the outer surface of the packing film. In an automatic packing device comprising a compression packing device for film-wrapping, and a primary binding device and a secondary binding device for banding a packing object wrapped in a packaging film in a cross shape, one of the binding devices. Is provided parallel to the transfer direction of the object to be packed, the specified binding machine is provided with an elevating mechanism for elevating and lowering the arch above the table, and the elevating mechanism is configured to It is configured such that the legs can be moved up and down between a bundling position where the legs come into contact with the upper surface of the table and a standby position where the legs are retracted above the transfer trajectory of the object to be packaged that is fed onto the table. As a requirement.

Preferably, the arch of the primary binding machine is configured so that it can be moved up and down by a lifting mechanism, and the arch is arranged parallel to the transfer direction of the object to be packed.

(Operation) In a binding machine having an ascending / descending arch, the arch is retracted to an upper standby position by an ascending / descending mechanism and waits for the next object to be packed. Then, when the object to be packed is sent to a predetermined position on the table, the arch is lowered to bring its legs into contact with the table so that the object to be packed straddles the object to be packed. When the binding machine is operated in this state, a band can be put on the object to be packed for binding. The bundled objects to be packed are sent out after raising the arch.

As described above, when the arch is moved up and down so that the packing object can be fed or unpacked, it is not necessary to change the posture of the packing object at least between the primary binding machine and the secondary binding machine, and the conventional apparatus can be used. In, it is possible to omit a turntable, which is required to be provided before and after the primary binding machine, and a diverting device such as a conveyor device.

In the mode in which the arch of the primary binding machine is operated to move up and down by the elevating mechanism, the object to be packaged can be transferred in a vertically long posture that does not easily collapse the load, and all packaging processing such as packaging and cross-shaped binding can be performed in the vertically long posture.

In addition, when there is no problem even when the packing target M is sent in a horizontal position, the primary binding machine 5 has the same configuration as the conventional binding machine, and the arch of the secondary binding machine 6 is moved up and down by the elevating mechanism to bind the cross-shaped binding. You can also do it.

(Effects of the Invention) As described above, in this invention, the arch of either the primary binding machine or the secondary binding machine for performing cross-shaped binding is moved up and down by the elevating mechanism to retract the arch upward. The objects to be packed are transferred in this state, and the objects to be packed are bound with the arch lowered on the table. Therefore, when applying cross-shaped bundling to the object to be packed, it is not necessary to change the posture of the object to be packed between the adjacent bundling machines, and the secondary bundling can be continued with the posture of the primary bundling being maintained. As a result, a turning device such as a turntable or a conveyor device, which is indispensable in the conventional device, can be omitted, and accordingly, the structure can be simplified, the installation area of the entire device can be reduced, and the facility cost can be reduced.

In addition, in the form in which the ascending / descending arch is provided on the side of the primary binding machine, the object to be packed can be transferred in a vertically long posture that does not easily collapse the load, and a series of packaging processing can be performed in the vertically long posture, so the feeding speed is improved. Moreover, the correction of the posture in each processing step can be omitted, improving the efficiency of the packing work as a whole,
Productivity can be improved.
