Soft bag automatic filling equipment for transfusion and method for filling transfusion soft bag

Abstract

The invention relates to soft bag automatic filling equipment for transfusion and a method for filling a transfusion soft bag. The soft bag automatic filling equipment comprises a rack and a PLC (Programmable Logic Controller). A bag feeding station and a bag transmission mechanism are arranged on the rack; at least one splicing opening is arranged at the bag feeding station; at least one clamping mechanical arm is arranged on the bag transmission mechanism; and the splicing opening is movably connected with the rack; the splicing opening is connected with a bag turnover mechanism; the bag turnover mechanism is connected with the PLC and drives the slicing opening to rotate along a vertical plane. The splicing opening is movably connected with the rack and can rotate along the vertical plane under the driving of the bag turnover mechanism, so that inclined angles of the splicing opening in an axial direction and a horizontal direction are adjustable, and a bag feeding process is faster and more comfortable. Particularly, when operators with different heights operate the soft bag automatic filling equipment to feed the soft bag, the inclined angels of the splicing opening can be adjusted to be comfortable according to the height of the operator and the height of the splicing opening, so that the operation comfort and the bag feeding efficient can be improved.

Description

technical field [0001] The invention relates to the field of soft infusion bag filling, in particular to a semi-automatic soft infusion bag filling device in a bag making section and a filling and sealing section, and a filling method thereof. Background technique [0002] Existing soft bag filling equipment for infusion is usually divided into two categories, one of which is an integrated bag making and filling production line, which integrates the production of soft bags for infusion and the filling process of soft bags for infusion, including the bag making section and filling process. In the sealing section, the infusion soft bag between the bag making section and the filling and sealing section is conveyed by a robot, which is suitable for manufacturers without a separate bag making machine. [0003] For example: the Chinese invention patent "A Soft Bag Infusion Production Line" with the application number of 200810183159.6 discloses a soft bag infusion production line,...

AI Technical Summary

Problems solved by technology

[0010] Although adopting such a structure, the infusion soft bag is more firmly connected to the insertion mouth, but it further increases the difficulty of manual bag loading; and the insertion mouth and the infusion soft bag with the same inner diameter of the bag must correspond one-to-one. Unable to adapt to various specifications of infusion soft bags with different inner diameters of the bag mouth

[0011] 3. Since the spout is usually in the shape of a tube, it is difficult for the operator to insert the opening of the soft infusion bag into the spout during manual bagging operation, resulting in difficulty and low bagging efficiency

[0012] Especially during production, in order to securely connect the mouth of the soft infusion bag with the spout, the inner wall of the soft infusion bag is usually fitted closely to the outer wall of the spout so that it has a certain tension, and such The structure further increases the difficulty of bagging

[0013] 4. During the bag loading process, it is difficult to confirm whether the infusion soft bag is installed in place. Therefore, it is easy to cause the infusion soft bag to fall off from the socket due to improper installation of the infusion soft bag and unstable clamping.

[0014] 5. Usually when the spout starts to move, the infusion soft bag that has not been bagged in place will start to fall off; due to the existing semi-automatic filling equipment, usually once the spout starts to move, it will enter the established filling and filling process. In the large cycle process of capping and bag discharge, if the soft bag is found to be loose or falling off at this time, it is difficult to reset the device and turn it back to the bag loading station to rearrange the infusion soft bag. The device lacks controllability and flexibility

[0015] 6. During the process of moving the infusion soft bag between the stations through the spout, the spout protrudes in the horizontal direction, which is prone to scratching, damage to the spout, and safety accidents

[0016] 7. Since the filling tube of the infusion soft bag is a flexible tube, it is easy to bend when the cap is subjected to vertical force, which affects the capping accuracy and yield

[0017] 8. The filling tube of the infusion soft bag is easy to be clamped on the clamping hand after being capped, and it is not easy to take it out. Usually, it is necessary to set up a manipulator with a complicated transmission mechanism to pick up the infusion soft bag and move it to the conveyor belt. The transmission of the manipulator Complex structure and high failure rate
