Description

Technical Field

[0001] This utility model relates to the field of medical consumables production equipment, specifically a feeding device for an infusion extension tube production line. Background Technology

[0002] During the assembly and processing of infusion tubing, the remaining components of the infusion tubing need to be glued to both ends of the infusion tubing. In the existing infusion tubing assembly and processing process, workers need to neatly place the infusion tubing into the storage box, and then place the storage box into the equipment's material handling position for normal equipment use.

[0003] However, during the production and processing process, there are often situations where the product is consumed but not replenished in time. This is mainly because if the storage bin is too deep, the material handling device cannot remove all the material, and the storage bin needs to be replaced; if the depth of the storage bin is just enough to meet the maximum material handling range of the material handling device, there is a problem of frequently needing to replace the storage bin; moreover, since the position of the material handling device is fixed, during the processing, after the infusion tube directly below the material handling nozzle is removed, a groove is formed, and when there is still a large amount of material left in the storage bin, the material handling device can no longer handle the material normally.

[0004] Furthermore, in the current assembly process of infusion tubing, the products are mainly arranged neatly in storage bins manually before being loaded. However, due to the large number of products, the arrangement is time-consuming, and the existing loading method requires frequent replacement of storage bins. This often leads to production line shutdowns due to the inability to replace storage bins in a timely manner. This situation seriously affects product quality and yield, thereby impacting production efficiency. Utility Model Content

[0012] Advantages of the utility model: This utility model has a simple structure and is easy to use. It adopts an automatic material storage box replacement method, which frees up time for workers to neatly place products into the storage box, solves the problem of line stoppage caused by untimely material storage box replacement, and improves production efficiency. It adopts an automatic left and right horizontal movement method for the storage box, which allows workers to replenish materials from both sides, solving the problem of too many products remaining in the storage box but unable to be retrieved normally.

[0021] A storage tank moving assembly 5, corresponding to the infusion extension tube suction assembly 4, is provided on the storage frame 1. The storage tank moving assembly 5 includes a pair of slide rails 5 on the platform of the storage frame 1, and the axis of the slide rails 5 is perpendicular to the axis of the frame 3.

[0022] Each slide rail 5a is equipped with a pair of sliders 5b, and a pair of horizontal plates 5c are connected across the two slide rails 5a. The lower end face of the horizontal plate 5c is connected and fixed to the corresponding slider 5b. An infusion extension tube storage tank 6 is installed on each horizontal plate 5c.

[0023] The infusion extension tube storage tank 6 includes a tank body 6a, a movable plate 6b inside the tank body 6a, and a material support trough 6c installed on the movable plate 6b. A set of longitudinally distributed material support trough guide rails 6d are connected to the inner walls of the tank body on both sides of the tank body 6a, and a set of guide grooves 6e corresponding to and cooperating with the material support trough guide rails 6d are provided on the groove wall of the material support trough 6c.

[0024] A linear moving device 5d is provided on the storage frame 1, which corresponds to and cooperates with the horizontal plate 5c. The linear moving device 5d is a motor-driven screw and nut device in the prior art. The horizontal plate 5c is moved along the slide rail by the linear moving device 5d. Below each storage rack 1 corresponding to each horizontal plate 5c, a bottom frame 5g is provided. The upper end of the bottom frame 5g is connected and fixed to the bottom surface of the horizontal plate 5c so that it can move together with the horizontal plate 5c. A lifting device 5e is provided on the bottom frame 5g. The output shaft of the lifting device 5e is connected and fixed to the bottom surface of the movable plate 6b. The lifting device 5e drives the material tray 6c to move up and down within the housing 6a. The lifting device 5e is a servo motor and lead screw lifting structure in the prior art, which will not be described in detail here.

[0025] A set of clearance elongated holes 5f are provided on the storage frame 1 to correspond to and cooperate with the bottom frame 5g, so that the bottom frame 5g can be moved together when the horizontal plate moves.

[0026] The feeding control module works in conjunction with the axial cylinder 4V, on / off sensor 4D, proximity switch 4H, negative pressure generator 4J, linear movement device 5D, and lifting device 5E to form an electrical signal control system.

[0027] Work process: First, infusion extension tubes are placed on the material trays inside the two boxes. One of the boxes is moved to below the infusion extension tube suction assembly by a linear motion device. The infusion extension tube suction assembly is then activated via the feeding control module to retrieve the material. During retrieval, an axial cylinder drives the suction tube to move longitudinally downwards into the box to retrieve the infusion extension tube.

[0028] When there are enough infusion extension tubes in the box, after a set of suction tubes have descended and picked up all the infusion extension tubes, the suction tubes, driven by the axial cylinder, lift one end of the infusion extension tube. At this time, the infusion extension tube clamping device in the next process above the frame will clamp the infusion extension tube and then drag it into the lowering process. When the infusion extension tube is clamped, the feeding control module will send a signal to stop the negative pressure generator from sucking air. This is the normal material picking process.

[0029] During this material handling process, the movable frame will also move up and down, and the proximity switch will send a signal to the feeding control module. However, since the suction tube can pick up the infusion extension tube, all the on / off sensors can send signals, so the feeding control module will not send a signal to the lifting device.

[0030] If the suction tube cannot pick up the infusion extension tube during the material picking process, the on / off sensor of the suction tube will not send a signal. At this time, the feeding control module will send a signal to the lifting device, which will start to lift the box upwards and move the movable frame upwards. When the proximity switch cannot detect the induction trigger rod, the feeding control module controls the lifting device to stop, and then the suction tube continues the material picking process.

[0031] However, even after the lifting device raises the box, if the suction tube's on / off sensor still doesn't send a signal (meaning that the suction tube cannot pick up the infusion extension tube), it will be considered that the box is in a material shortage state. The feeding control module will trigger the material replacement program, that is, the feeding control module controls the lifting device of the box below the infusion extension tube suction component to reset, and at the same time starts the linear movement device to move the box with material to the bottom of the infusion extension tube suction component to continue picking up material, while the box with material shortage will be moved to the outside of the storage frame so that the staff can replenish the material.
