Description

The present invention relates to an attachment / detachment structure for a component fixing clip .

  Conventionally, as shown in FIGS. 7 (a) and 7 (b), as a component fixing structure, a frame (device support) 2 provided with a convex portion 1 on the upper surface, a glove (component) 3 combined with the frame 2, An elastic substantially U-shaped stopper (clip) 4 that clamps the frame 2 and the globe 3 is formed, and a chevron portion 5 that bulges upward is formed on the upper piece of the stopper 4 and is convex. There is a glove for a lighting fixture provided with a hole 6 for inserting and locking the portion 1 (see Patent Document 1).

  And if the convex part 1 of the frame 2 is inserted and locked into the hole 6 of the stopper 4, the edge of the hole 6 bites into the convex part 1 due to elasticity, and a glove for lighting equipment without rattling is obtained. It is.

  By the way, as shown in FIG. 8 (a), in the conveying device of the food processing line, for example, the conveying device 15 of the fried (conveyed food) 10 attached to the udon or the like, the shutter ( A two-sheet flow detection sensor (parts) 12 and an arrival detection sensor (parts) 13 of the fried chicken 10 are installed at a position where they are temporarily stopped at an unillustrated position.

  Each of the sensors 12 and 13 is fixed by a plurality of sets (two sets in this example) of bolts and nuts 16 while being supported by the support surface of the support base 14 attached to the transport device.

  Further, as shown in FIG. 8B, in the transport device 22 for the noodle dough (transported food) 17, the upstream conveyor is located at a position where it falls from the upstream conveyor 18 as indicated by an arrow e and transfers to the downstream conveyor 19. A scraper (component) 20 is installed to scrape off the noodle dough 17 adhering to 18 toward the downstream conveyor 19.

  The scraper 20 is fixed by a plurality of sets (four sets in this example) of bolts and nuts 16 while being supported by a support surface of a support base 21 attached to a downstream conveyor (conveying device) 19.

  In the food processing line transport apparatus as described above, the sensors 12 and 13 are fixed to the support base 14 with the bolts and nuts 16 or the scraper 20 is fixed to the support base 21 with the bolts and nuts 16 as follows. Depending on the reason.

  That is, at the end of each day, it is necessary to remove the sensors 12 and 13 and the scraper 20 from the support bases 14 and 21 for cleaning by removing the bolts and nuts 16 and to reattach the support bases 14 and 21 with the bolts and nuts 16 again. Because there is.

Japanese Patent No. 2649126

  However, at the end of each day, there is a problem that it takes a lot of work and time to remove and re-install the bolts and nuts 16 of a large number of groups (there are tens of groups in the actual line). .

  In addition, the bolts and nuts 16 are unavoidably loosened naturally due to vibrations of the conveying device, etc., and should not be dropped into the food being conveyed.

  For this reason, it is also conceivable to use a configuration in which the glove (part) 3 is clamped and fixed to the frame (device support base) 2 shown in FIG. However, when an impact is applied to the globe 3 from the direction of the arrow a, the stopper 4 can be easily opened in the direction of the arrow b, and the globe 3 may fall off from the frame 2. If the globe 3 falls off, Since 4 may also fall off at the same time, it cannot be used as it is in a conveying device of a food processing line.

The present invention has been made to solve the above-mentioned problems, and is particularly suitable for a conveying device of a food processing line, and can be attached and detached quickly and reliably with one touch, and there is no possibility of dropping off due to impact or vibration. An object of the present invention is to provide a structure for attaching / detaching a fixing clip .

In order to solve the above-mentioned problems, the present invention provides a support base that is attached to a conveying device of a food processing line and has a plurality of positioning protrusions or positioning holes formed on a support surface, and a support surface of the support base. A supported part, a positioning hole or a positioning projection formed , a sensor for detecting the transported food or a scraper for scraping off the transported food, and a part in which the positioning hole is fitted in the positioning projection. Elasticity that is formed in a substantially U shape in side view so that it can be sandwiched with elastic force from the side at the same time, and has a through hole that fits into the positioning protrusion protruding from the part or the support base clip becomes in the of the piece section and the other piece of the resilient clip, said through when the distal end side of the piece part at least the through-hole is formed is lifted with fingers or tools The so Hazuseru disconnect from the projecting portions for positioning, there is provided a mounting and dismounting the structure of the clip parts fixed, characterized that you have bent outwardly.

According to the present invention, the positioning hole is passed through the plurality of positioning protrusions, thereby supporting the component that is the sensor or the scraper in the positioning state on the support surface of the support base. Next, if the clip and the part and the support base are simultaneously sandwiched by the elastic force from the side, one piece of the clip rides on the positioning projection and bends, while the through hole fits into the positioning projection and penetrates. Become. Accordingly, the component can be clamped and fixed to the support base of the apparatus with the clip (attachment of the clip).

On the contrary, the clip can be pulled out to the side in a state where the tip end side of one piece of the clip bent outward is slightly lifted with a finger or a tool and the through hole is removed from the positioning projection ( Clip removal).

  In this way, unlike the work of removing and attaching using bolts and nuts, the work of attaching and removing using clips can be performed quickly and reliably with one touch. In addition, the clip does not loosen naturally due to the vibration of the transport device, unlike bolts and nuts, and it does not fall out into the food being transported. .

  Further, referring to FIG. 2 (b) of the embodiment, when an impact is applied to the component from the direction of arrow a, the component drops from the support base because the positioning hole penetrates the positioning projection. Since the clip does not open in the direction of the arrow b, the clip is not likely to drop off.

In addition, by bending the tip end of at least one of the one piece and the other piece of the clip outwards, when the component and the support base are sandwiched with the elastic force from the side at the same time, the tip end is attached to the part or support stand. Since it does not come into contact, the pinching operation can be performed smoothly.

In addition, the clip can be attached and removed quickly and reliably with a single touch, and there is no risk of falling off due to impact or vibration. It is most suitable for food processing line performed in

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1, FIG. 2 and FIG. 6 (a) show a first embodiment, which is a transport device for a food processing line, for example, a transport device 15 for fried (transport food) 10 attached to udon or the like.

  As shown in FIG. 6 (a), the two-sheet flow detection sensor (parts) 12 of the fried chicken 10 and the arrival detection are located at a position where the chute 11 slides down as indicated by an arrow d and is temporarily stopped by a shutter (not shown). Sensor (parts) 13 is installed.

  A support base 26 is attached to the conveying device 15 at a position where the frying 10 is temporarily stopped. As shown in FIG. 1 (a), the support base 26 is formed by joining a base portion 26b of a stepped upper plate 26a and a base portion 26d of a planar lower plate 26c in a side view in a stacked manner. . The upper plate 26a and the lower plate 26c are substantially parallel with a predetermined interval T therebetween. The upper surface of the upper plate 26a becomes the support surface 26e, and the lower surface of the lower plate 26c becomes the support surface 26f.

  A plurality (two in this example) of positioning holes 12a and 13a are formed in the sensors 12 and 13, respectively. The positioning holes 12a and 13a are originally for passing bolts 16 (see FIG. 8A), and are already opened in the commercially available sensors 12 and 13.

  On the support surface 26e of the upper plate 26a, positioning protrusions 27 are formed so as to protrude upward corresponding to the positioning holes 12a of the two-sheet flow detection sensor 12, respectively. On the support surface 26f of the lower plate 26c, positioning projections 27 are formed so as to protrude downward corresponding to the positioning holes 13a of the arrival detection sensor 13, respectively. The positioning projection 27 is welded and fixed to the lower surface of the upper plate 26a or the upper surface of the lower plate 26c.

  Then, as shown in FIG. 2A, the positioning protrusions 27 of the support surface 26e of the upper plate 26a are passed through the positioning holes 12a of the double-flow detection sensor 12, so that the sensor 12 is The support surface 26e of the plate 26a is supported in a positioned state.

  Similarly, the positioning holes 13a of the arrival detection sensor 13 are passed through the positioning projections 27 of the support surface 26f of the lower plate 26c so that the sensor 13 is positioned on the support surface 26f of the lower plate 26c. Become supported.

  Note that the mounting angles of the sensors 12 and 13 can be adjusted by changing the mounting angle of the support base 26 and the mounting angle of the positioning projection 27.

  On the other hand, an elastic clip 30 formed in a substantially U shape in a side view is provided so that the sensor 12 and the upper plate 26a or the sensor 13 and the lower plate 26c can be sandwiched by elastic force from the side simultaneously. .

  The clip 30 is formed with a through-hole 30c that fits into the positioning projection 27 and passes through one piece 30a on the sensor 12 and 13 side.

  Further, as shown in FIG. 1B, the distal end side 30d of both the one piece 30a and the other piece 30b (or only one of them) of the clip 30 is bent outward.

If the sensor fixing clip 30 is attached / detached in the conveying device 15 of the frying 10 as described above, the sensor 12 is placed on the positioning projection 27 of the upper plate 26a of the support base 26 as shown in FIG. By passing through the positioning hole 12a, the sensor 12 is supported in the positioning state by the support surface 26e of the upper plate 26a.

  Next, as shown in FIGS. 1 (b) and 2 (b), when the sensor 30 and the upper plate 26a are simultaneously sandwiched by the clip 30 with elastic force from the side (see the arrow in FIG. 1 (b)), the clip As the one piece 30a of the 30 rides on the positioning projection 27 and bends, the through hole 30c fits into the positioning projection 27 and penetrates. Thereby, the sensor 12 can be clamped and fixed to the upper plate 26a of the support base 26 by the clip 30 (attachment of the clip 30). The procedure for holding and fixing the lower plate 26c of the support base 26 and the sensor 13 with the clip 30 is the same.

  On the contrary, the clip 30 can be pulled out to the side in a state where the tip portion of the one piece 30a of the clip 30 is slightly lifted with a finger and the through hole 30c is removed from the positioning projection 27 (removal of the clip). ). The procedure for removing the lower plate 26c of the support base 26 and the clip 30 of the sensor 13 laterally is the same.

  In this way, unlike the conventional removal and attachment operations using bolts and nuts, the attachment and removal operations using the clip 30 can be performed quickly and reliably with one touch. In addition, the clip 30 does not loosen naturally due to vibration of the conveying device 15 or the like like a bolt or nut, and it does not fall out into the fried chicken 10 during conveyance, so effective measures to prevent foreign matter from entering. It becomes.

  Further, referring to FIG. 2B, when an impact is applied to the sensors 12 and 13 from the direction of the arrow a, the sensors 12 and 13 use the positioning holes 12 a and 13 a as the positioning protrusions 27 of the support base 26. Therefore, the clip 30 does not open in the direction of the arrow b, so that the clip 30 does not drop out.

  Further, when the distal end side 30d of both the one piece portion 30a and the other piece portion 30b of the clip 30 is bent outward, the sensor 12 and 13 and the support base 26 are simultaneously sandwiched by the clip 30 with elastic force from the side. Since the tip end 30d does not hit the sensors 12, 13 and the support base 26, the sandwiching operation can be performed smoothly.

  Furthermore, the clip 30 can be attached and removed quickly and reliably with a single touch, and there is no risk of falling off due to impact or vibration. Therefore, the clip 30 can be effectively prevented from being mixed in. It is most suitable for the conveying apparatus 15 of the food processing line performed like this.

  3, 4, and 6 (b) are a second embodiment, which is a transport device for a food processing line, for example, a transport device 22 for noodle dough (transport food) 17.

  As shown in FIG. 6B, the noodle dough 17 attached to the upstream conveyor 18 is directed toward the downstream conveyor 19 at a position where it falls from the upstream conveyor 18 as indicated by an arrow e and transfers to the downstream conveyor 19. A scraper (component) 20 is installed for scraping off.

  A support base 33 is attached to the transport device 22 of the downstream conveyor 19. As shown in FIG. 3A, the support base 33 is formed in a substantially U shape in plan view, and the front surface of the front plate 33a is a support surface 33b.

  In the scraper 20, a plurality (four in this example) of positioning holes 20a are formed in pairs in the left and right positions. The positioning hole 20a is originally for passing the bolt 16 (see FIG. 8B), and is formed in the scraper 20 in advance.

  On the support surface 33b of the front plate 33a, corresponding to the positioning holes 20a of the scraper 20, the positioning projections 34 are formed to protrude forward. Each positioning projection 34 is fixed by welding to the rear surface of the front plate 33a.

  Then, as shown in FIG. 4 (a), each positioning projection 20 on the support surface 33b of the front plate 33a passes through each positioning hole 20a of the scraper 20, so that the scraper 20 supports the front surface of the front plate 33a. 33b is supported in the positioning state.

  On the other hand, two elastic clips 35 formed in a substantially U shape in side view are provided so that the scraper 20 and the front plate 33a can be sandwiched by elastic force from below at the same time.

  A through hole 35c is formed in one piece 35a of each clip 35 on the side of the scraper 20 so as to fit into the two left or right positioning projections 34 and pass therethrough.

  Moreover, the front end side 35d of both the one piece part 35a of each clip 35 and the other piece part 35b (only one is also possible) is bent outward.

If the scraper fixing clip 35 is attached / detached in the conveying device 22 for the noodle dough (conveyed food) 17 as described above, a positioning projection on the front plate 33a of the support base 33 as shown in FIG. By passing the positioning hole 20a of the scraper 20 through the portion 34, the scraper 20 is supported in a positioned state by the support surface 33b of the front plate 33a.

  Next, as shown in FIGS. 5A and 5B, when the scraper 20 and the front plate 33a are simultaneously sandwiched by the clip 35 with elastic force from below (see the arrow in FIG. 5A), one piece of the clip 35 is obtained. While 35a rides on the positioning projection 34 and bends, the through hole 35c fits into the positioning projection 34 and penetrates. Thereby, the scraper 20 can be clamped and fixed to the front plate 33a of the support base 33 by the clip 35 (attachment of the clip 35).

  On the contrary, as shown in FIGS. 5C, 5D and 5E, the one piece 35a of the clip 35 is slightly lifted by the bar-shaped tool 36, and the through hole 35c is removed from the positioning projection 34. The clip 35 can be removed downward (see the arrow in FIG. 5E) (removal of the clip 35).

  In this way, unlike the conventional removal and attachment operations using bolts and nuts, the attachment and removal operations using the clip 35 can be performed quickly and reliably with one touch. Further, the clip 35 is not loosened naturally due to the vibration of the conveying device 22 or the like like a bolt and a nut, and is not likely to fall into the noodle dough (conveyed food) 17 being conveyed. This is a measure to prevent contamination. Other functions and effects are the same as those of the first embodiment.

  In the above embodiment, the positioning holes 12a, 13a, 20a are formed in the sensor 12, 13 or the scraper 20, which are parts, and the positioning protrusions 27, 34 are formed in the support bases 26, 33. It is also possible to form positioning protrusions on the sensors 12 and 13 or the scraper 20 and to form positioning holes on the support bases 26 and 33.

  Moreover, in the said embodiment, although the conveying apparatus of the food processing line (The conveying apparatus 15 of the fried chicken 10 and the conveying apparatus 22 of the noodle dough 17 as an apparatus was taken as an example, the sensors 12 and 13 and the scraper 20 were taken as an example. It goes without saying that it is not limited to.
