Specifically, the first detection module 301 can detect the size of the items, and during the process of the sliding mount 31 moving along the item, the first detection module 301 can detect the size of the items in the direction during the first detection module 301 follows the sliding mount 31 to move; and then, it is strapped according to a predetermined strapping rule, based on the specific measured size. The rule setting for the strapping quantity of items of different sizes in a certain direction will not be limited or described herein.
At the same time, since the bottom of the items to be strapped is typically supported by a tray, the strapping tape requires passing through a forklift hole on the tray and simultaneously avoiding a pad in the bottom of the tray. Considering the influence of the tray, the sliding mount 31 is further provided with a second detection module 302 for detecting the position of the forklift holes on the tray carrying the items to be strapped, and in particular, during movement of the sliding mount 31 along the items, on the one hand, the first detection module 301 can detect the size of the items themselves, and the other hand, the second detection module 302 can also measure the tray under the items to determine the position of the forklift hole on the tray. In this way, during the strapping process, the strapping position and quantity of the strapping tape are determined according to the overall size of the item and the position of the forklift hole on the tray, so as to realize the self-adaptive strapping operation.
There are a variety of forms for the representation entities of the first detection module 301 and the second detection module 302. For example, the first detecting module 301 and the second detecting module 302 can use a photoelectric sensor, and the photoelectric sensor can detect whether there is an object blocking in front of the photoelectric sensor, so that, the size parameters of the items and the position of the forklift hole on the stray can be detected, according to the switch signal of the photoelectric sensor combined with the servo motor to drive the movement and displacement of the sliding mount 31. Alternatively, the first detection module 301 and the second detection module 302 can use an image collector (such as a camera), to obtain the physical dimensions of the object and the positions of the forklift holes and the pads on the tray using image recognition techniques, and the specific methods related to image processing may be referred to conventional image processing techniques, which are not limited or described herein.
Wherein, regarding the manner in which the above-mentioned motor output power realizes the transmission connection, the manner of adding a speed reducer to the rotating shaft of the motor may be adopted, which will not be limited or described herein.
The present invention also provides a strapping method for a rotary translation baler apparatus, specifically comprising: conveying the items to be strapped below the support frame 1, moving the translational strapping module 3 in a first direction, and performing multiple strapping operations on the item, and then rotating the translational strapping module 3 90 degrees and moving in a second direction to perform multiple strapping operations on the items.
Specifically: in the actual use process, items to be strapped are transported to the strapping station of the rotary translational strapping apparatus through a conveyor line or a forklift. By moving the translational strapping module 3, the strapping operation in the first direction is performed, and after the processing is completed, the translational strapping module 3 is rotated and the translational strapping module 3 continuously moved to perform the strapping operation in the second direction.
Wherein, the specific strapping operation includes the following steps:
Step 1, moving the translational strapping module 3 along the first direction and measuring a length dimension of the items to be strapped in the first direction, after the items to be strapped are conveyed below the support frame 1. The items are placed at the strapping station formed by the support frame 1, and then the rotary module 2 drives the translational strapping module 3 to move along the first direction of the items to measure the size of the items in the first direction by the first detection module 301.
Step 2, calculating a strapping quantity and a strapping position of a strapping tape in the first direction, according to the measured length dimension information of the items to be strapped in the first direction.

Step 3, moving the translational strapping module in a reverse direction of the first direction, and bundling the strapping tape at the calculated strapping position on the items to be strapped. Specifically, the translational strapping module 3 is driven to move in the opposite direction to strap the items in the first direction.
Step 4, rotating the translational strapping module 3 to rotate 90 degrees outside of the items to be strapped by a rotary module 2, and moving the translational strapping module 3 in a second direction and measuring a length dimension of the items to be strapped in a second direction. After the strapping operation in the first direction is completed, the translational strapping module 3 needs to be rotated, so that the translational strapping module 3 is rotated to the second direction for cross strapping processing. After the translational strapping module 3 completes the strapping operation in the first direction, it moves to one end of the slide rail to avoid the items, and then rotates 90 degrees again.
Step 5, calculating a strapping quantity and a strapping position in the second direction, according to the measured length dimension information of the second direction. When strapping in the second direction, after measuring the size of the items in the second direction at step 4, the strapping position and the number of times of strapping in the second direction are calculated again.
Step 6, moving the translational strapping module in a reverse direction of the second direction, and bundling the strapping tape at the calculated strapping position on the items to be strapped.
Further, considering the influence of the bottom tray of the items during the strapping process, the step 1 further includes: detecting a location of a forklift hole on the bottom tray of the items to be strapped in the first direction, during the movement of the translational strapping module 3 along the first direction. Specifically, the position of the forklift hole in the first direction of the tray is detected by the second detection module 302, and when calculating the strapping position, the pad of the tray is avoided so that the strapping tape passes through the forklift hole for strapping. Correspondingly, the step 2 further includes: calculating the number of bundling and the strapping position of the strapping tape in the first direction, according to the measured length and dimension information of the items to be strapped and the position information of the forklift hole in the first direction.
Similarly, in the process of strapping the items in the second direction, the step 4 further includes: detecting a position of a forklift hole in the bottom tray of the items to be strapped in the second direction, during movement of the translational strapping module 3 in the second direction; and the step 5 further includes: calculating a number of bunding and a strapping position of strapping tape in the second direction, according to the measured length dimension information of the items to be strapped and the forklift hole position information in the second direction.

Similarly, in order to achieve automatic film breaking, a film breaking mechanism 43 is provided to automatically cut the film after it has been wound. With respect to the embodied entities of the clamping mechanism 42 and the film breaking mechanism 43, reference may be made to a related configuration in a strapping machine for wrapping a plastic film net around an item disclosed in Chinese Patent No. 2004100353283, which is not limited or described herein.
