Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, and more specifically, to a palletizing system for assisting in palletizing woven bags. Background Art

[0002] In the civil explosive industry, explosive articles have special properties. When the finished products are transported at the last link of the production line, there is a sympathetic detonation distance for each woven bag on the production line, which strictly limits the production speed and cannot be too fast. To ensure production safety, enterprises often adopt manual palletizing in the palletizing link.

[0003] However, when dealing with woven bags with a large weight, manual palletizing will greatly increase the labor intensity, and it is difficult for workers to bear such high-intensity labor for a long time. To solve this problem, enterprises usually increase the number of workers, but this undoubtedly increases the cost. At present, although fully automatic palletizing robots have advantages in palletizing efficiency, for the civil explosive industry, on the one hand, their cost is relatively high and enterprises are difficult to bear; on the other hand, due to the special properties of explosive articles, their safety cannot be guaranteed. Therefore, in the civil explosive industry, there is an urgent need for an auxiliary device with a relatively low cost, which can not only assist workers in completing the palletizing work, but also effectively reduce the labor intensity, improve the palletizing efficiency, and ensure the safety and reliability of the production process. Therefore, a palletizing system for assisting in palletizing woven bags is proposed. Summary of the Utility Model

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As shown in the attached Figures 1-4 A palletizing system for assisting in palletizing woven bags shown in the figure includes a palletizing drive structure 1, a fixed pulley moving structure 2, an auxiliary palletizing hopper structure 3, and a step ladder structure 4. The palletizing drive structure 1 includes a three-phase motor 101. A winch 102 is fixedly installed at the output end of the three-phase motor 101. A steel wire rope 103 is fixedly connected to the output end of the winch 102. A second fixed pulley 104 and a movable pulley 105 are arranged outside the steel wire rope 103. The fixed pulley moving structure 2 includes a servo electric cylinder 201. A linear guide rail 202 is fixedly installed at the output end of the servo electric cylinder 201. An I-shaped connecting piece 203 is slidably connected to the top of the linear guide rail 202. The bottom of the fixed pulley moving structure 2 is fixedly installed on the first fixed pulley 204.

[0023] As shown in the attached Figure 1 、 4 figure, the auxiliary palletizing hopper structure 3 includes a hopper 301. A handle 302 is fixedly connected to the top of the hopper 301. A baffle 303 is fixedly connected between the hopper 301 and the handle 302. A rope 305 is fixedly connected to the outside of the handle 302. A balance plate 304 is fixedly installed on the outside of the rope 305. The top of the rope 305 is fixedly connected to a rotating connecting piece 306. The rotating connecting piece 306 is fixedly connected to the movable pulley 105, which is convenient for assisting manual operations to achieve the functions of grasping, moving, and changing the direction of palletizing woven bags.

[0024] As shown in the attached Figure 1 figure, the step ladder structure 4 includes a palletizing base 401. A through groove 402 is opened on the bottom surface of the palletizing base 401, which is convenient for staff to step on through the step ladder structure 4 for assisting palletizing and is convenient for dealing with the situation of relatively high palletizing height.

[0025] As shown in the appendix Figure 4 As shown, the cross-sectional shape of the hopper 301 is trapezoidal. The side with a larger area of the hopper 301 is used for feeding, and the side with a smaller area is for discharging, which facilitates the sliding in and out of the woven bags.

[0026] As shown in the appendix Figures 1-3 As shown, the steel wire rope 103 successively bypasses the second fixed pulley 104, the first fixed pulley 204 and the movable pulley 105, which facilitates changing the magnitude and direction of the force by using the pulley block. The use of the movable pulley 105 reduces the pulling force provided by the three-phase motor 101 and facilitates the use of electricity with a smaller power.

[0027] As shown in the appendix Figure 1 As shown, the connection between the three-phase motor 101 and the winch 102 is fixed by carbon steel bolts to ensure the installation stability of the three-phase motor 101 and the winch 102, thereby ensuring the stability during the driving of the device.

[0028] Working principle of the present utility model: During the use of a palletizing system for assisting in palletizing woven bags provided by the present utility model, first, the servo cylinder 201 in the fixed pulley moving structure 2 is controlled to work, pushing the I-shaped connector 203 on the linear guide 202 to move, thereby driving the first fixed pulley 204 fixedly installed at the bottom to move towards the end of the production line, so that the hopper 301 in the auxiliary palletizing hopper structure 3 reaches the position of the production line discharge port. When the hopper 301 is at the production line discharge port, the woven bags fall into the hopper 301. After loading is completed, the operator controls the direction of the hopper 301 through the handle 302, and by the cooperation of the fixed pulley moving structure 2 and the palletizing driving structure 1, the hopper 301 is moved to the designated position of the pallet. After reaching the designated position of the pallet, the unloading operation is performed. After the unloading is completed, one palletizing is completed. After the palletizing is completed, the three-phase motor 101 in the palletizing driving structure 1 drives the winch 102, and through the action of the steel wire rope 103 and the pulley block, the hopper 301 is lifted to prepare for the next palletizing;

[0029] The three-phase motor 101 of the palletizing drive structure 1 provides a power source. Driven by the three-phase motor 101, the hoist 102 performs the operation of winding and unwinding the steel wire rope 103 fixedly connected to its output end. By passing the steel wire rope 103 around the second fixed pulley 104, the first fixed pulley 204 and the movable pulley 105, the force generated by the hoist 102 is transmitted to the auxiliary palletizing hopper structure 3 to realize the lifting of the hopper 301, and the direction and magnitude of the force are changed by the second fixed pulley 104 and the movable pulley 105. The servo cylinder 201 of the fixed pulley moving structure 2 provides a driving force. Under the action of the servo cylinder 201, the linear guide 202 enables the I-shaped connecting member 203 slidably connected to the top to move along the linear guide 202. The I-shaped connecting member 203 is connected to other components and slides on the linear guide 202. The first fixed pulley 204 serves as a support and guiding component for the steel wire rope 103. In the auxiliary palletizing hopper structure 3, the cross-sectional shape of the hopper 301 is trapezoidal and is used to load woven bags. The handle 302 facilitates the manual operation of the hopper 301. The baffle 303 located between the hopper 301 and the handle 302 plays a protective role. The balance plate 304 is connected to the handle 302 by a rope 305 to keep the hopper 301 balanced during the lifting process. The rope 305 is used to connect the handle 302 and the balance plate 304 and the rotating connecting member 306 at the top. The rotating connecting member 306 is fixedly connected to the movable pulley 105, enabling the hopper 301 to rotate within a certain range.

[0030] Finally: The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
