Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

According to an embodiment of the present invention, as shown in Figure 1, it is a schematic diagram of the overall structure of the transmission mechanism realized according to the present invention, wherein the transmission mechanism includes the following main parts: charging mechanism 1, charging mechanism limiting device 2 and a storage mechanism 3, wherein the charging mechanism 1 is used to clamp and transport the disposable infusion tube used for packaging, and the loading mechanism limit device 2 is used to carry the charging mechanism 1, so that it is convenient to use with the storage mechanism 3 For docking, the storage mechanism 3 is used to temporarily arrange and store the infusion tubes to be processed later, so that they will not be blocked during the transportation process, wherein the charging mechanism 1 and the storage mechanism 3 are docked at substantially the same height, The disposable infusion tube can be smoothly transmitted between the two.

The storage mechanism 3 includes a storage slideway 3-1 for temporarily receiving the infusion tube transferred from the charging mechanism 1, and also includes a spacer 3-2 that is subsequently connected to the storage slideway 3-1, It is used to arrange the infusion tubes one by one, and process them into a state that meets the processing standards at a certain distance.

As shown in Figure 2, the charging mechanism 1 is embodied as a charging trolley, which includes a conveying track part and a trolley support, wherein the conveying track part includes a track part and a docking part, and the track part and the docking part are integrated, wherein the conveying The track of the track part is used to carry and transport the infusion tube, and the docking part is used to dock with the storage mechanism 3 to transport the infusion tube.

The track part includes two tracks parallel to each other and similar in structure, one track is used to clamp the filter 4 of the infusion tube, and the other track holds the puncture part of the infusion tube, and the tube body part of the infusion tube hangs from the two tracks In the space between, thus to realize the transmission.

The structure of the two tracks is as follows: from top to bottom, it includes: toggle conveyor belt 1-4, limit sheet metal 1-1, load conveyor belt 1-3 and load roller 1-2, and a section of load conveyor belt 1-3 It is installed in the carrying roller 1-2 to ensure the carrying capacity of the conveyor belt 1-3. The limit sheet metal 1-1 is used to limit the infusion tube and prevent it from deviating from the track under the force of the tube body during the transportation process. .

In the work, the two ends of the infusion tube (filter and puncturer) are manually put into a limit space formed by the carrying transmission belt 1-3 and the limit sheet metal 1-1, and the infusion tube is manually placed on the right side of the trolley. Put them into the track one by one, so that the infusion tubes are continuously arranged in the limiting space formed by the carrying transmission belt 1-3 and the limiting sheet metal 1-1. Since the carrying transmission belt 1-3 is long and has insufficient bearing capacity, five carrying rollers 1-2 are added between the carrying transmission belt 1-3 to ensure the carrying capacity of the carrying transmission belt 1-3. In addition, the driving conveyor belt 1-4 is powered by the driving gear 1-5 arranged on the docking part of the charging trolley 1, wherein the driving gear 1-5 is arranged on the left side of the charging trolley 1, and passes through the belt pulley arranged on one side of the track part 1-9 drives the rotation of the carrying conveyor belt 1-3, thereby realizing the synchronous action of the stirring conveyor belt 1-4 and the carrying conveyor belt 1-3, thereby driving the infusion tube to transport forward. The two tracks of the charging trolley 1 can use the coupling 1-7 to realize power transmission, so that it is not necessary to set drive gears at the ends of the butt joints of the two tracks for transmission.

Wherein, the main function of stirring the conveyor belt 1-4 is to give power to the infusion tubes arranged continuously to move forward. Since both ends of the filter and the puncturer need to be limited, there must be friction between the surface of the limited sheet metal 1-1 and the infusion tube, resulting in resistance. Therefore, it is necessary to use a load-carrying conveyor belt 1-3, which can significantly reduce the number of infusion tubes. Resistance to forward movement to prevent jamming.

As shown in Fig. 3, the limit device 2 of the charging mechanism is a frame-shaped support structure, and the uppermost layer directly in contact with the charging trolley 1 is a rectangular support that opens toward the insertion direction of the charging trolley 1. Two protruding positioning blocks 2-1 are arranged in the middle of the bracket rails in the length direction, which clamp the bracket rails at the lower part of the charging trolley 1 by means of groove engagement, and the above two bracket rails are provided with a Several rollers 2-2, which can realize auxiliary support for the bracket track at the lower part of the charging trolley 1, and the two rows of rollers 24 on the industrial aluminum profile can reduce the resistance when the charging trolley 1 is inserted. In addition, the rollers 2-2 The width is 518mm, which is greater than the width of the charging trolley 1, which is 485mm, so that the charging trolley 1 can be easily inserted, and at the same time, a positioning clamp plate 2-3 is arranged on the inner side of a bracket track along the width direction to realize further locking and fixing of the trolley .

Four adjustable feet 2-5 are installed at the bottom of the limit device 2 of the charging mechanism to adjust the height of the charging trolley 1. Since the slideway of the charging trolley 1 needs to be docked with the slideway of the buffer mechanism 2, this The charging trolley 1 has higher positioning requirements. Further, the iron-absorbing sheet 1-12 can also be installed at the front end of the bracket track at the bottom of the trolley 1, and be connected with the magnet 2-4 installed on the inside of a bracket track in the width direction of the loading mechanism limiter 2, Prevents the trolley from coming out after being inserted into the packaging machine.

As shown in Figure 1, the charging trolley 1 is erected on the loading mechanism limit device 2, so the charging trolley 1 and the loading mechanism limit device 2 constitute a manual auxiliary feeding module, and this method uses two The way the module is set up, when the charging trolley 1 is pulled out, its casters will often rub against the ground, which will easily cause the wear of the casters, which will affect the docking accuracy between the slideway of the charging trolley 1 and the subsequent transfer equipment. The wear of the casters is avoided from affecting the precision, so the service life of the charging trolley 1 can be significantly maintained by adopting this method.

As shown in Figure 4, the overall structure of the storage mechanism 3 is shown in the figure, which includes a storage slideway 3-1 and a spacer 3-2, wherein the storage slideway 3-1 is mainly connected with the charging trolley 1. For docking, the material storage slideway 3-1 also includes two parallel tracks. Compared with the length of the charging trolley 1, the buffer mechanism 3 is relatively short, and the probability of the transfusion tube being stuck is much lower. The track of the material chute 3-1 includes, from top to bottom, the material storage dial conveyor belt 3-1-1, the bottom surface sheet metal that carries the infusion tube, and the side sheet metal that restricts the filter on the side, wherein the material storage dial The moving conveyor belt 3-1-1 is driven by a motor 3-1-4 arranged on the side of the track as a driving source, wherein the motor 3-1-4 also drives the main gear 3-1-3 to drive the intermediate gear 3-1-2, In this way, it is transmitted to the driving gear 1-5 of the charging trolley 1, thereby realizing the synchronous transmission action of the storage mechanism 3 and the charging trolley 1, wherein the two slideways of the storage slideway 3-1 also adopt a coupling transmission in the form of a device. In order to facilitate the engagement of the drive gear 1-5 of the charging trolley 1 with the intermediate gear 3-1-2, the axis of the intermediate gear 3-1-2 becomes higher. Under the action of this driving force, the infusion tube is transported from the charging trolley 1 to the slideway on the buffer mechanism 3 .

As shown in Figure 5 below, it is to illustrate how the charging trolley 1 and the storage slideway 3-1 are connected. The front end of the charging trolley 1 is provided with a section of feeding sheet metal 1-13, and its front end is equipped with an infusion tube stopper. Claw 1-14, which takes the direction perpendicular to the track as the axis, realizes rotation on the plane of the insertion direction of charging trolley 1, and the torsion spring 1-15 is installed on the rotating shaft of gear claw 1-14, when there is no external force , the pawl 1-14 can rotate clockwise. When the charging trolley 1 is pulled out from the buffer mechanism 3, the pawl 1-14 has no external force, and can rotate clockwise under the action of the torsion spring 1-15, and the rotating arm emerges from the plane of the feeding sheet metal 1-13, Thereby directly block the slideway of the infusion tube, to prevent the workers from loading the infusion tube on the right side, while the infusion tube falls from the left side. When the loading trolley 1 is inserted into the buffer mechanism 3, the infusion tube bears against the pawl 1-14, so that the pawl rotates counterclockwise from 1-14, and the rotating arm then turns to below the load pulley 1-9, which is lower than the feeding sheet metal 1 -13 plane, the infusion tube can pass through to reach the buffer mechanism 3 .

And as shown in Figure 6, be the setting mode on the material storage slideway 3-1, be to adopt the track lower end of the storage material slideway to arrange the spring top block 3-1-5, when two parts were docking, the spring The top block 3-1-5 acts on the pawl 1-14, so that the infusion tube can reach the storage slideway 3-1 from the charging trolley smoothly.

On the storage chute, the infusion tubes are arranged continuously without intervals on the chute. However, due to the requirements of production efficiency, it is usually necessary to make 6 infusion tubes into a group, and the distance between each infusion tube is 50mm. Packaging, the latter is other processing operations, so behind the material storage slideway 3-1, a spacer 3-2 is arranged next to it, which is used to arrange the infusion tubes on the material storage mechanism 3 into a set interval.

As shown in Figure 4, a spacer 3-2 is continuously installed behind the storage slideway 3-1, and its manifestation is a continuous track that is continuously arranged at the rear ends of the two parallel tracks of the storage slideway 3-1. The design mode of code wheel 3-2-4 as shown in Figure 7 has been realized, and it has rotating wheel 3-2-3, finger 3-2-2-3, code wheel 3-2-4 and coding upper evenly distributed Composed of six pins 3-2-8 and the first linear guide rail 3-2-5, wherein the rotary wheel 3-2-3, the coding wheel 3-2-4, the pin 3-2-8, etc. pass through the connecting plate 3-2-5 2-7 is connected with the second linear guide rail 3-2-6, and the second linear guide rail 3-2-6 is used to support the base plate 3-2-11 for supporting the infusion tube, and the base plate 3-2-11 has a base plate concave Groove, and the pin 3-2-9 of several claws 3-2-2-1 and limit claws are arranged on the base plate 3-2-11, and the base plate 3-2-11 links to each other with the push plate 3-2-12 , the push plate 3-2-12 is connected with the cylinder 3-2-13, through the action of the cylinder 3-2-13, the first linear guide rail 3-2-5 also moves closely, thus making the code wheel rotate 60° , because the rotating wheel 3-2-3 is coaxial with the coding wheel 3-2-4, the rotating wheel 3-2-3 also rotates 60°, so that the filter 4 of the first infusion tube enters the rotating groove and the bottom plate groove In the matching groove of 3-2-10, the cylinder 3-2-13 reciprocates once, the rotating wheel 3-2-3 then rotates 60°, the first infusion tube is pushed out by the claw, and enters the next bottom plate 3-2-11 On the forward claw on the top, at the 3-2-4 end of the code wheel, the second infusion tube enters the rotating groove, and the sequence is similar, and in this way, every time the cylinder 3-2-13 moves, the claw is moved toward A section of fixed interval distance is conveyed before, thus the infusion tubes are evenly arranged one by one on the spacer 3-2.
