Description

  The present invention relates to an erecting transmission device for a continuously variable transmission belt element that erects and transmits a continuously variable transmission belt element introduced from a feeder.

  Conventionally, a main passage that passes a face-up pierce nut and a branch passage that passes a face-down pierce nut to a feeding chute that feeds a pierce nut with a low protrusion as a pilot part on the front side to an automatic assembly machine And a guide groove through which the pilot portion engages and passes is provided in the branch passage, and the face-down pierce nut and the face-down pierce nut are selected by feeding the face-down pierce nut into the branch passage. (For example, see Patent Document 1).

However, the pierce nut is different from the front and back in the axial direction, but the outer peripheral surface orthogonal to the axis is rectangular, and therefore does not need to be aligned in the vertical direction. For this reason, it cannot be applied to elements that require vertical alignment, such as a plate-like continuously variable transmission belt element in which a head portion having a protrusion formed on the front side is connected to the body portion. There has been a demand for the development of an apparatus for aligning the two.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an erecting delivery device for a continuously variable transmission belt element that can be sent out in an upright posture with the continuously variable transmission belt element inserted from an alignment feeder.

  The present invention provides an inclined feed groove that slides and feeds a plate-like continuously variable transmission belt element having a head part with a protrusion formed on the front side connected to the body part in an upright state. A continuously variable transmission that has an element introduction guide portion inclined toward the groove on the side, the start end portion of the element introduction guide portion faces the discharge port of the alignment feeder, and the end portion cannot be inserted into the inclined delivery groove passage According to a first aspect of the present invention, there is provided an erecting device for continuously variable transmission belt element as a discharge portion for discharging the belt element. An upright delivery device for an infinitely variable continuously variable belt element that is inclined is defined as the invention of claim 2, and in the invention of claim 1 or 2, an element thickness gate or A ment front / back sorting mechanism or an erecting device for continuously variable transmission belt elements provided with an element thickness gate and an element front / back sorting mechanism is defined as the invention of claim 3, and in the invention of claim 3, the element front / back sorting mechanism is A common path having a rear guide groove that guides the protrusion of the head portion of the continuously variable transmission belt element and a front guide groove that guides the protrusion of the head portion of the continuously variable transmission belt element facing the front, and is branched from the common path An upright feed device for a continuously variable transmission belt element comprising a rear-facing element branch path having only a rear guide groove and a front-facing element branch path having only a front guide groove. .

  The present invention provides an inclined feed groove that slides and feeds a plate-like continuously variable transmission belt element having a head part with a protrusion formed on the front side connected to the body part in an upright state. A continuously variable transmission that has an element introduction guide portion inclined toward the groove on the side, the start end portion of the element introduction guide portion faces the discharge port of the alignment feeder, and the end portion cannot be inserted into the inclined delivery groove passage By adopting the discharge part that discharges the belt element, even if the continuously variable belt element that is discharged and dropped from the discharge port of the alignment feeder gets stuck and does not fit smoothly into the inclined feed groove, the element introduction guide The continuously variable transmission belt element is guided and inserted into the inclined delivery groove by the inclination toward the inclined delivery groove while sliding on the part. In addition, the continuously variable transmission belt element that is turned upside down due to the impact when fed from the alignment feeder slides through the element introduction guide without being inserted into the inclined delivery groove by the projection of the head, and the end is discharged. Therefore, only the upright continuously variable transmission belt element is sent to the next process. Further, when the lateral continuously variable transmission belt element rotates while sliding on the element introduction guide portion and assumes an upright posture, it is inserted into the inclined delivery groove and sent out.

  Further, as described in claim 2, by making the inclination of the element introduction guide portion steeply inclined from the starting end portion facing the feeder discharge port, the posture of the continuously variable transmission belt element that slides on the element introduction guide portion is further raised. It becomes a state. For this reason, since the insertion into the inclined delivery groove is performed more smoothly and rapidly, the distance of the continuously variable transmission belt element can be shortened, and the delivery time can be shortened. In addition, since the laterally variable continuously variable belt element can be promptly rotated and can be quickly shifted to a stable posture, the insertion and non-insertion processing into the inclined feed groove can be performed in a short time, The distance of the element introduction guide portion can be shortened.

  According to the third aspect of the present invention, the element thickness gate or the element front / back sorting mechanism or the element thickness gate and the element front / back sorting mechanism are provided after the inclined feed groove, so that the dimensional accuracy is below the standard due to distortion or the like. Since the continuously variable transmission belt element is stopped from being delivered, it is possible to accurately prevent the occurrence of defective products. Further, since the reverse continuously variable transmission belt element is sorted and removed by the element front / back sorting mechanism, it is possible to accurately prevent the occurrence of defective products. Further, by providing the element thickness gate and the element front / back sorting mechanism, it is possible to eliminate the dimensional accuracy below the standard and the reverse continuously variable transmission belt element.

  5. The front guide for guiding the projection of the head portion of the continuously variable belt element and the rear guide groove for guiding the projection of the head portion of the continuously variable transmission belt element facing forward, and the projection of the head portion of the continuously variable transmission belt element facing upward as described in claim 4. It is composed of a common path with a groove, a reverse element branch path with only a rear guide groove branched from the common path, and a front element branch path with only a front guide groove. It is possible to sort the front and back continuously variable transmission belt elements without using. In addition, since the power is not consumed, the running cost can be reduced and the product can be used for a long time without failure.

Next, a preferred embodiment of the present invention will be described in detail with reference to the drawings.
In FIGS. 1 and 2, reference numeral 1 denotes a chute that feeds the continuously variable belt belt W in a normal posture discharged from the discharge port 2a of the alignment feeder 2 in an upright posture, and the chute 1 has an inclination of about 45 °. I'm giving it back. The chute 1 is provided with an inclined delivery groove 3 and an element introduction guide 4 that is inclined toward the groove on one side of the inclined delivery groove 3, and the element introduction guide 4 is a starting end. The discharge portion 5 discharges the continuously variable transmission belt element W in a non-upright posture, the end of which is faced to the discharge port 2a of the alignment feeder 2 and the terminal end of the alignment feeder 2 cannot be inserted into the inclined feed groove 3. As shown in FIGS. 11 and 12, the continuously variable transmission belt element W has a shape in which a head portion H having a protrusion V formed on the front side is connected to the body portion B.

  The alignment feeder 2 aligns the top and bottom and the front and back of the plate-like continuously variable transmission belt element W fed from the molding process. The alignment feeder 2 has different plate thicknesses (1) as shown in FIG. .7 mm, 1.8 mm) continuously variable transmission belt elements W are arranged in parallel with a first alignment feeder for 1.8 mm and a second alignment feeder for 1.7 mm. .

  As shown in FIG. 10, the discharge port 2 a of the alignment feeder 2 is formed above the bottom of the inclined cylindrical container 20 of the alignment feeder 2, and the element fitting of the cutting turntable 21 provided on the upper surface of the bottom of the inclined cylindrical container 20. The vertical opening width is smaller than the vertical opening width of the joint hole 21a. For this reason, the lower end edge of the discharge port 2a is exposed by several millimeters from the element fitting hole 21a, and when the continuously variable transmission belt element W is dropped and discharged from the discharge port 2a, the lower surface of the front end of the head portion H Is hung on the lower edge of the opening of the discharge port 2a. Due to this hooking state, the continuously variable transmission belt element W is rotated in the clockwise direction so that the head portion H faces upward and is sent out to the inclined feed groove 3.

  As shown in FIG. 13, the chute 1 is a first chute for delivering a continuously variable belt element W for 1.8 mm discharged from the first alignment feeder, and 1.7 mm discharged from the second alignment feeder. And a second chute for delivering the continuously variable transmission belt element W.

  In addition, the inclination of the element introduction guide 4 is steep (angle α) except for the starting end facing the discharge port 20a of the alignment feeder 2, and the continuously variable transmission belt element W is inserted into the delivery groove 3 Even if the length of the element introduction guide portion 4 is short, the function can be sufficiently performed and the delivery speed can be improved.

  Reference numeral 30 denotes an element thickness gate provided in the inclined feed groove 3, and the element thickness gate 30 is formed with a gap equal to the thickness of the body portion B of the continuously variable transmission belt element W to be passed. The feeding of the continuously variable transmission belt element W exceeding the thickness of the body part B is stopped and eliminated.

  Reference numeral 31 denotes an element front / back sorting mechanism. The element front / back sorting mechanism 31 includes a rear guide groove 32a for guiding the protrusion V of the head portion H of the continuously variable transmission belt element W facing backward and the head of the continuously variable transmission belt element W facing forward. A common path 32 having a front guide groove 32b for guiding the protrusion V of the portion H, a reverse element branch path 33 having only a rear guide groove 32a branched from the common path 32, and only the front guide groove 32b. When the continuously variable transmission belt element W that is turned upside down is mixed, the continuously variable transmission belt element W that is turned upside down is selected and eliminated.

  In the structure configured as described above, the processed continuously variable transmission belt element W is first put into each alignment feeder 2 according to the thickness. The continuously variable transmission belt element W is deposited on the bottom of the inclined cylindrical container 10 of the alignment feeder 2, but the continuously variable transmission belt element W is a rotating cutout rotating disk provided at the bottom of the inclined cylindrical container 10. Only one element is fitted into each element fitting hole 11 a formed in 11 and lifted above the inclined cylindrical container 10.

  At this time, the continuously variable transmission belt element W that is not sufficiently fitted into the element fitting hole 11a, the upside down continuously variable transmission belt element W, or the inverted continuously variable transmission belt element W is fitted into the element fitting hole 11a. The cutting turntable 11 is slid down and returned to the bottom of the alignment feeder 2 without being latched.

  Then, the continuously variable transmission belt element W fitted and latched in the element fitting hole 11a is sent to the upper side of the inclined cylindrical container 10 and discharged from the discharge port 10a as shown in FIG. 3 is introduced into the element introduction portion guide portion 4. Since the continuously variable transmission belt element W is engaged with the lower end edge of the discharge port 10a which is smaller than the element fitting hole 11a when being introduced into the element introduction guide portion 4, the continuously variable transmission belt element W is engaged with the continuously variable transmission belt element W. The element W falls while rotating in the clockwise direction, and the head portion H is located on the upper side and falls on the element introduction guide portion 4 with the body portion B facing downward.

  Then, the continuously variable transmission belt element W that has fallen on the element introduction guide portion 4 is fed into the inclined feed groove 3 while sliding on the upper surface of the element introduction guide portion 4. However, the continuously variable transmission belt element W whose top and bottom and front and back sides are reversed by the impact when dropping onto the element introduction guide portion 4 is inserted into the inclined sending groove 3 due to the protrusion V of the head portion H interfering with it. It will slide on the element introduction guide part 4 without being done. During this sliding, a part of the continuously variable transmission belt element W taking a lateral posture rotates on the element introduction guide portion 4 and takes a normal posture. It will be inserted into. Then, the continuously variable transmission belt element W that has not been in the upright posture is slid through the element introduction guide portion 4 without being inserted into the inclined delivery groove 3, and is discharged from the discharge portion 5 formed at the end thereof.

  In the continuously variable belt element W in an upright posture that slides in the inclined feed groove 3, the dimensional accuracy is below the standard due to processing distortion or the like, or the element thickness gate set to 1.7 mm If a 1.8 mm continuously variable transmission belt element W is mixed in 30, these cannot be passed through the element thickness gauge 30, so that only the continuously variable transmission belt element W having a reference dimension is sent out.

  Then, the continuously variable transmission belt element W that has passed the thickness inspection is fed into the element front / back sorting mechanism 31. The common path 32 having the front guide groove 32b and the rear guide groove 32a of the element front / back sorting mechanism 31 allows the continuously variable transmission belt element W having both front and back sides to pass through, but is branched after the common path 32. Since only the front guide groove 32b is formed in the front element branch path 33, and only the rear guide groove 32a is formed in the back element branch path 34, the continuously variable transmission belt element W facing forward moves straight. It is introduced into the face-up element branch path 33. Then, the reverse continuously variable transmission belt element W advances obliquely upward, is introduced into the reverse element branch path 34, and is discharged from the end.
