Bag feeding device

The present invention relates to a packaging bag feeding device, and more particularly to a bag feeding device suitable for various types of packaging bags.

Since most modern industries are highly automated, high-volume production systems can be quickly produced, and raw materials have the advantage of large purchases, which are more cost-effective. However, because each process flow of the automation system has certain procedures and specifications, if there is a change, another set of corresponding process flow and specifications for the change must be designed.

For small and diverse products or specifications, most manufacturers can only replace parts of the automation system by hand to fulfill diverse needs. However, manual production not only increases personnel costs, but also prolongs the production process, and the quality of the finished product will vary depending on the proficiency of the personnel.

Taking the toilet paper product packaging as an example, the standard product packaging is assumed to be a package of 12 packs. Manufacturers can order 12-pack reel bags in an automated system to automate the rapid packaging process and complete product packaging operations. However, in response to store promotions or product positioning differences, downstream manufacturers may require 14 bags, 24 bags, or other different packaging specifications.

In order to change the production system for these small and diverse requirements, and to order the full-size bags of the corresponding specifications, in addition to adding additional costs, the remaining materials will also be idle. waste. Most manufacturers choose to order small quantities of bulk bags and use manual bagging to meet the needs of small and diverse. However, this method solves the problem of material waste on the surface, but increases the labor cost and the process time.

Please refer to FIG. 1 to FIG. 4 , which are schematic views of the arrangement, side view, top view and rear view of the packaging portion according to an embodiment of the invention. The bag feeding device 20 of the present invention comprises: a rack module 24, a conveyor belt 21, a frame 22, two suction cup modules 26 and two servo motors 28. The rack module 24 is configured to stack a plurality of packages 201. The frame 22 is disposed above the rack module 24 and the conveyor belt 21, and is provided with two slide rails 225. In this embodiment, the slide rail 225 is disposed between the front shelf 221 and the rear shelf 223, but is not limited thereto. The suction cup modules 26 are respectively disposed on the two sliding rails 225 and are movable on the sliding rails 225 for sucking and moving the packaging bags 201 from the rack module 24 onto the conveyor belt 21. The servo motor 28 is used to drive the corresponding suction cup module 26 to move on the corresponding slide rail 225.

In an embodiment of the present invention, each of the suction cup modules 26 includes a suction cup fixing rod 269, at least one suction cup swing arm 263 and a suction cup power module 27. Among them, the suction cup fixing rod 269 is for fixing at least one suction cup 261, and the at least one suction cup swing arm 263 is connected to the suction cup fixing rod 269. The suction cup power module 27 is used to drive the suction cup swing arm 263 to swing up and down. When the suction cup 261 is located above the rack module 24, the suction cup power module 27 can drive the suction cup swing arm 263 to swing downward, and the suction cup fixing rod 269 and the suction cup 261 are lowered to the position of the packaging bag 201. After sucking the package 201, the suction cup power module 27 drives the suction cup swing arm 263 to swing upward to an intermediate position. At this time, the servo motor 28 drives the suction cup module 26 to move over the conveyor belt 21, and moves the sucked bag 201 to an appropriate position on the conveyor belt 21. After the suction cup 261 places the packaging bag 201 on the conveyor belt 21, the suction cup power module 27 drives the suction cup swing arm 263 to swing upward to a higher position, and then the servo motor 28 drives the suction cup module 26 to return to the rack module 24 Above.

In an embodiment of the present invention, the two suction cup modules 26 can sequentially suck the packaging bag 201 and displace the conveying belt 21, and use the different positions of the suction cup swinging arms 263 to make the suction cup 261 staggered. The zones are staggered and the package 201 is placed on the conveyor belt 21 in turn. According to this principle, the feeding speed of the packaging bag can be improved.

In one embodiment of the present invention, each of the suction cup power modules 27 includes a ball spline 271, a splined linear bearing 273, a first bevel gear 275, a second bevel gear 277, and a spline driver 270. . The ball spline 271 is disposed on the frame 22 in parallel with the slide rail 225. The spline linear bearing 273 is disposed on the suction cup module 26 and sleeved on the ball spline 271 to slide on the ball spline 271 and rotate together with the ball spline 271. The first bevel gear 275 is fixed to the splined linear bearing 273 and disposed coaxially with the splined linear bearing 273. The second bevel gear 277 connects the first bevel gear 275 and the at least one suction cup swing arm 263, and the at least one suction cup swing arm 263 can be swung up and down according to the driving of the first bevel gear 275. The spline driver 270 is disposed on the frame 22 and is coupled to the ball spline 271 to drive the ball spline 271 to rotate.

In one embodiment of the invention, the spline driver 270 includes a spline swing arm 279 and a dual-stroke pneumatic cylinder 278. The one end of the spline swing arm 279 is connected to the ball spline 271, and the ball spline 271 is used as a rotating shaft. The other end of the spline swing arm 279 is connected to the double stroke pneumatic cylinder 278. With the three states of the two-stroke pneumatic cylinder 278, the ball spline 271 can be rotated to three angles, via the spline linear bearing 273, the first bevel gear 275, the second bevel gear 277, and the suction cup swing arm 263. The suction cup 261 is moved to three fixed heights and the servo motor 28 is driven to drive the suction cup module 26 to the appropriate position for operation, as shown in FIG.

In one embodiment of the invention, the spline driver 270 can also be implemented as a servo motor (not shown). The same effect as the foregoing embodiment can be attained by the servo motor driving the ball spline 271 to an appropriate angle.

In an embodiment of the invention, each of the suction cup modules 26 further includes a fixing base 265 and an extension rod 267. The fixing seat 265 is connected to the at least one suction cup swing arm 263 and the extension rod 267, and the suction cup fixing rod 269 is disposed at the end of the extension rod 267. By the arrangement of the fixing seat 265 and the extension rod 267, the suction cup 261 can be kept in a fixed direction to facilitate the work, and the amplitude of the swing of the suction cup swing arm 263 can be reduced, and the angle at which the ball spline 271 is rotated can be reduced.

In an embodiment of the invention, the rack module 24 includes at least one rack 241 and an elevator 244. The rack 241 is used to stack the bag 201, and the elevator 244 is used to drive the rack 241 to rise and fall, thereby moving the bag 201 to an appropriate height to match the operation of the chuck module 26. Wherein, the elevator 244 can be implemented by a hydraulic cylinder. In addition, a lifting seat 243 can be disposed between the elevator 244 and the rack table 241 to keep the rack 241 stable.

In an embodiment of the invention, the rack module 24 further includes a detector. 247, used to detect the height of the package 201. The package can be moved to an appropriate height in conjunction with the elevator 244.
