An automatic banding packing machine is provided with a packing machine body having an upper-face table on which the object to be packed passes, a pair of vertical band guide arches arranged separately from each other above the upper-face table in a direction parallel with a passage direction of the object to be packed, and a horizontal band guide arch arranged above the upper-face table in the direction parallel with the passage direction of the object to be packed, and the pair of vertical band guide arches is configured to be movable between a standby position separated from the horizontal band guide arch and a communication position communicating with the horizontal band guide arch in a direction orthogonal to the passage direction of the object to be packed.

Automatic banding packing machine and automatic banding packing system

A banding packing machine capable of inexpensively detecting the end of a band reel, thereby contributing to a reduction in cost. In a banding packing machine having a back pool box in a packing machine body and serving to feed an unused band (B) stored in the back pool box and a band from a band reel, the rotating speed of a touch roller is detected when a required amount of band is being pulled out of the band reel wherein the band is not left in the band reel if the rotating speed is not changed but the rotation is carried out at an almost constant speed, and the tip portion of the band does not arrive at the predetermined position of a band guide arch. Then, the driving operation of a normal rotating roller is stopped based on the decision signal.

Banding packing machine

It is an object to provide an automatic banding packing machine capable of easily removing the ring of a band with a simple structure when idle banding is carried out. When the rear end side of a band is to be pulled back by band pull-back means (), an amount of the pull-back is detected by detecting means. It is decided that idle banding of the band is carried out when a result of the detection is greater than a preset length and the band is wound around a slide table. Thereafter, the rotation of a cam shaft () is temporarily stopped based on a signal, whereby the timing of the pressing to be carried out by a middle presser member, which is operated after melting the superposing portion of the band by means of a heater (), is delayed in a predetermined time.

Automatic banding packing machine

A band refeeding method in a banding packing machine is disclosed which can prevent the tip portion of a band from being excessively pulled back even if the band is not supplied correctly but is automatically pulled back, and can stay the band in a predetermined position and can successively supply the band to the band guide arch side. A length of a band to be pulled back to an original position by band pull back means is previously detected based on the number of rotations of a touch roller constituting band supply means. In addition, the number of rotations of the touch roller before reaching a predetected set value is detected when the tip portion of the band is pulled back. Then, a rotating speed of a roller of the band pull back means is reduced when the number of rotations is detected. Therefore, the roller of the band pull back means is subsequently rotated at the low speed, thereby pulling back the tip of the band to a predetermined position.

Strapping packing machine

A touch roller can be moved between three positions. In the first position, the touch roller is pressed onto a forward driving roller. In the second position, the touch roller is pressed onto a reverse driving roller with two different forces. In the third position, the touch roller is spaced from both the forward driving roller and the reverse driving roller. When the touch roller is pushed onto the reverse driving roller with a small force, the reverse driving roller pulls back a band and wraps the band around an article to be packed. When the touch roller is pushed onto the reverse driving roller with a large force, the reverse driving roller tightens the band wrapped around an article.

Band-applying apparatus and method for use in packing system

A band charging apparatus for a packing machine capable of carrying out charging of a band while effectively preventing jamming of the band. In the packing machine, a band unwound from a reel is fed to a pool box by means of the band charging apparatus, to thereby be temporarily stored in the pool box. Then, the band is fed to a circumference of a package by means of a band feeding and tightening apparatus. Thereafter, the band is drawn back by means of the band feeding and tightening apparatus while a distal end of the band is kept gripped, resulting in being tightly wound on the package. The band charging apparatus includes a pool feed roller for carrying out feeding of the band to the pool box and a pool touch roller arranged so as to access to the pool feed roller through the band. Also, the band charging apparatus includes guide plates for defining a band guide path in the pool box when the band is set for charging of the band in the band feeding and tightening apparatus. The guide plates are pivotally moved in a direction of guiding the band, to thereby close the guide plates. When the band is excessively fed to the band guide path, nerve of the band in the band guide path causes the guide plates to be open, to thereby release the band guide path, resulting in the band being stored in the pool box.
