Description

[Detailed description of the invention] "Field of industrial application" This invention relates to a crushing and cutting device for used syringes.

``Prior Art'' In the past, it has been difficult for used syringes to be crushed and cut by a rotary blade that cuts the used syringes sufficiently after the syringes are placed in the hopper. This is due to the fact that the syringe cannot be fed at right angles to the rotary blade, and the shearing action between the rotary blade and the fixed blade allows the needle to fall from between the rotary blades without damage. However, there were some defects that made it difficult to simplify the equipment.

``Problems to be solved by the invention'' This invention is an extremely simple method for crushing syringes, in which syringes, especially free syringe needles, are fed at right angles to the rotary blades, and the syringe needles are not cut or dropped from between the blades. The purpose is to obtain a cutting device.

``Means for solving the problem'' This proposal includes a pawl gear provided on the machine frame, a tooth trace blade formed at the tip of the pawl, and a cross-slope groove type feeder provided on the downward rotation side of the gear. , is constituted by a syringe crushing and cutting device in which a cutting portion is formed by providing a blade receiving portion having a receiving surface in contact with the tooth line blade at the lower end of the supply tool.

``Operation'' Therefore, when used syringes are introduced from above the cross-slope groove type supply device 4, the syringes slide down the cross slopes 4', 4' from the upper end of the supply tool 4 toward the lower end. Following the cross slope 4'4', the longitudinal direction of the syringe is aligned at right angles to the tooth line blade 3 of the lower pawl gear 2, and the tooth line blade 3, which rotates downward and descends, is placed on the receiving surface 5. The syringe is crushed in close proximity, and the blade 3 touches the receiving surface 5 and passes over the receiving surface 5, thereby receiving the crushed pieces and the thin syringe needle between the blade 3 and the receiving surface 5. It is cut on the surface 5 by the tooth trace blade 3. The crushed pieces and cut pieces are discharged downward by the pawl 11 of the gear 2.

``Example'' Two upright plates 8, 8 are arranged in parallel inside the machine frame 1, and the pawl gear 2 is pivotally supported between the upright plates 8, 8, and connected to the rotating shaft 10 by a key 9. Fixed in the direction of rotation.
The pawl 11 of the pawl gear 2 is formed by a radial surface 11' and an inclined surface 11'', and a tooth trace blade 3 is formed at the intersecting protruding portion of both surfaces 11' and 11''. Then, the gear 2 rotates in the direction shown by arrow a in FIG. Support. At the lower end of the supply tool 4 thus constructed, a cutting portion 7 is formed by extending a blade receiving portion 6 having a receiving surface 5 in contact with the tooth trace blade 3. This blade receiving part 6 can be freely adjusted up and down around the horizontal bolt 12, and the receiving surface 5
is brought into contact with the tooth segment blade 3. The intersecting slopes 4', 4' of the supply tool 4 and their intersections are plated with hardened chrome 4'', and the plated surfaces are polished to a mirror finish, so that a sharp injection needle tip can penetrate easily.
It is best to form it to prevent it from getting caught and to allow it to slide.
Further, the receiving surface 5 is hardened by induction hardening. Further, the pitch of the tooth line blades 3, 3 is formed to be shorter than the injection needle. In addition, 13 in the figure is a cam for adjusting and supporting the lower surface of the blade receiver 6, 14 is a support shaft for adjusting its rotation, 15 is an arcuate long hole bored in the upright plates 8, 8, and 16 is the same length. A pin slidably fitted into the hole 15, 17 in FIG. 2 is a support hole for the pin, 18 is a disinfectant spray nozzle, 19 is a disinfectant tank, 20 is a disinfectant pump, 21 is a disinfectant hose, 22 23 is a waste paper bag removably provided at the opening of the hopper 22; 24 is a foldable opening plate of the paper bag 23; 25 is double-sided tape; 26
is an adhesive, 27 is a deceleration rotating gear of pawl gear 2, 28
29 is the drive gear that meshes with the gear 27, 29 is the prime mover, 30 is the pedestal for the paper bag 23, and 31 is the supporting spring for the pedestal 30, which lowers when the waste in the paper bag reaches 1 kg and connects to the b contact. The switch 32 is opened to stop the prime mover 29. The disinfectant pump 20 operates when the prime mover 29 starts and ends, and sprays disinfectant from the nozzle 18 for 3 seconds. Further, 33 is an operation control panel, 34 is a chute for charging used syringes, 3
5 and 36 are opening/closing lids. The pawl 11 of the pawl gear 2 is 8
Approximately 20 pieces can be set up. Also, Figures 7 and 3 in Figure 8
7 is a synthetic resin waste storage box, 38 is its lid,
39 is a check claw.

``Effects'' Since the present invention is configured as described above, it is possible to feed used syringes with their longitudinal direction almost perpendicular to the tooth line blade 3 of the pawl gear 2, and it is possible to easily receive a thin and short object such as a syringe needle. 5, and a blood-stained syringe made of synthetic resin can be crushed by crushing by the action of the tooth line blade 3 and the receiving surface 5, and cut by the same blade 3 and the receiving surface 5. This provides a crushing and cutting machine that not only can reliably crush and cut used syringes and the like that may have blood on them without getting them caught in the upward rotation side of the pawl gear 2, but also has a simple structure.
