DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a binding band processing apparatus for a package, and more particularly, to a band and a string fastened to a package of various products so as to prepare for unpacking. .

[0002]

2. Description of the Related Art Conventionally, empty cans, PET bottles, and the like delivered to a manufacturing plant for beer, juice, etc., are arranged in a plane in a standing posture and are stacked vertically with sheets of cardboard or the like sandwiched therebetween. For this packing, two or three bands made of polypropylene or the like are wrapped around the bulk cargo in the vertical direction to prevent collapse of the load.

Conventionally, the operation of cutting and removing such a band has been manually performed, but the present applicant has disclosed a binding band removing apparatus capable of automating the operation in Japanese Utility Model Laid-Open No. 7-21507.

That is, the binding band removing device includes a puller device for separating the band from the surface of the package, a clamp device for holding the separated band, a cutter device for cutting the clamped band, and a tip side of the cut band. And a shredding device for cutting the band from the collection device into fine pieces, wherein the band hitting the surface of the package is a puller. The band is cut off from the surface by the device and kept in this state by the clamp device, and the band is cut at the part where the cutter device has been separated.Then, the cut band is pulled out to the collection device side, and the band is cut from around the package. Was removed, and the band from the collection device was cut into fine pieces by a shredding device and disposed of.

[0005]

However, the binding band removing apparatus still has the following problems.

That is, for example, in the case where the package is not a bulk product described above but a container or the like placed on a standard pallet, the band serving as a binding band is wrapped around the container through a through hole formed in the pallet, and Will be bound tightly on the pallet.However, depending on the size of the container, the container end may be located inside the pallet end, and the band will be inclined from the container top to the pallet so that the skirt spreads. As a result, a gap is formed between the band and the side surface of the container.

In addition, since the distance between the end of the container and the end of the pallet is not constant, and the containers may be stacked in multiple stages, the inclination angle of the band is various, and the angle of the band is the same as the conventional binding band described above. When the automatic processing is performed by the removing device, there is a problem that the band cannot be clamped smoothly because the clamp position is set at a fixed position based on the clamp device.

In this case, even if the band can be cut, the band is not clamped, so that the band cannot be pulled out or the drawn band cannot be guided to the cutting device.

An object of the present invention is to provide a binding band processing apparatus for a package which can solve the above-mentioned problems.

[0010]

Therefore, in order to solve the above-mentioned problems, according to the present invention, there is provided a claw body for searching for a binding band wrapped around a package, and a binding band searched for by the claw body. And a cutter device for cutting the binding band clamped by the clamping device, wherein the clamping device is a movable holding piece that can be moved forward and backward by a clamping actuator, and A pair of fixed holding pieces is provided with a holding portion that clamps the binding band with a fixed holding force, and a holding portion advance / retreat actuator that enables the entire holding portion to advance / retreat with respect to the package.

Further, in the present invention, the operating force of the holding portion advancing / retreating actuator is made smaller than the tension of the binding band, and the movable holding piece advances and presses the binding band with a reaction force. The entire holding portion was retracted, and the strap was clamped at a position balanced with the tension of the strap.

According to the third aspect of the present invention, in the binding band processing device for the package, a shredding device for shearing the cut binding band into small pieces while drawing the cut binding band is provided. In order to guide the tip to the shredding device entrance, the clamping device was pivotable.

Further, according to the present invention, there is provided a guide body for guiding the claw body in the direction of the binding band in response to the positional displacement of the package in the direction perpendicular to the direction in which the binding band is wound. I decided that.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a claw body for searching for a binding band wrapped around a package, a clamping device for clamping the binding band found by the claw body, and a cutting of the binding band clamped by the clamping device. In the binding band processing device having a cutter device, the clamping device clamps the binding band with a fixed holding force by a movable holding piece that can be advanced and retracted by a clamp actuator and a fixed holding piece that forms a pair with the movable holding piece. And a holding portion advance / retreat actuator which enables the entire holding portion to advance / retreat with respect to the package.

With this configuration, the clamp position when the movable holding piece advances and clamps the binding band can be changed based on the binding band, and then the binding unit is cut by the cutter device. Can be.

For example, when the package is a container or the like placed on a standard pallet, the binding band is wrapped around the container through a through hole formed in the pallet, and the container is tightly bound on the pallet. However, when the container end is located inside the pallet end, the binding band is wrapped in an inclined state so as to spread out from the upper surface of the package to the pallet, so that the binding band and the packing It will be separated from the body surface.

In the present invention, since the holding portion is provided with an actuator for moving the holding portion forward and backward with respect to the package body, the movable holding piece advances to clamp and comes into contact with the binding band. In addition, when the user tries to press, the entire holding portion retreats, and accordingly, the fixed holding piece also retreats, so that the clamp can be reliably clamped at a position based on the binding band.

More specifically, the operating force of the holding portion advancing / retreating actuator is made smaller than the tension of the binding band, and the entire holding portion is retracted by the reaction force of the force by which the movable holding piece advances and presses the binding band. It is preferable that the strap is clamped at a position balanced with the tension of the strap.

Therefore, according to the present invention, even if the downward inclination of the binding band is different depending on the size of the package and the distance between the binding band and the surface of the package is variously varied, the clamp position is determined as the binding band reference according to the present invention. Therefore, reliable clamping is always possible.

Since the clamp position is desirably below the cutting end for the reason described later, the cutter device is disposed above the clamp device.

Further, the positional relationship between the claw body and the fixed holding piece and the movable holding piece of the holding portion is such that the binding band is located between the fixed holding piece and the movable holding piece at the position where the claw body has searched for the binding band. It is good to set to be located.

In order to facilitate post-processing of the cut ties as described above, a shredding device for shearing the cut ties while pulling the cut ties is provided. The clamping device can be configured to be pivotable to guide it to the shredding device entrance.

That is, when the binding band is cut after being clamped, the clamping device is pivoted upward so that the cut end of the binding band faces the entrance of the shredding device, and the binding band is finely sheared by the shredding device while being pulled out from around the package. And make it easier to dispose of.

Further, a guide may be provided for guiding the claw body in the direction of the binding band in response to the positional shift of the package in the direction orthogonal to the direction in which the binding band is wound.

Preferably, the guide body is provided substantially directly above the claw body. When the packing body is, for example, a container, the claw body moves laterally to search for a binding band, and the guide body is moved laterally while abutting the container surface. When moved, the claw body can reliably locate the zip ties.

In the case where containers are placed in two or more rows, when the processing of the binding band of one container is completed and the process proceeds to the next, depending on the loaded state of the containers, The distance between the edge and the edge of the pallet may be different, and there may be a step between each container.However, since the guide is provided, it is possible to trace the next container surface smoothly. it can. Therefore, also in this case, the work of cutting, pulling out, and shearing can be sequentially performed while the claw body surely finds the binding band.

As described above, according to the present invention, even when the binding band is extended from the upper surface of the package to the flared state and the gap is formed between the binding band and the surface of the package, the binding band is formed. Can be reliably clamped with reference to the position of, and the subsequent operation of cutting, pulling out, and shearing the cable ties can be automated, and labor can be saved.
