[0032]

[0033]infigure 2 A vibration conveyor 1 according to the first embodiment of the present embodiment is shown. In addition,figure 2 In the left and right directions (length direction) of the figure, the direction of the penetration is set to the left and right directions, and will be described below. The vibration conveyor 1 includes a groove 3, which is supported by the support portion 2 on the ground G, and can reciprocate in the front-rear direction; and the driving portion 4 for reciprocating the recess 3.

[0034]infigure 2 In the middle, the support portion 2 supports the front and rear ends of the groove 3, but there is also a support portion 2 in the left and right ends, and the groove 3 is supported in four parts. Each of the support portions 2 includes a fixed block 21, which is fixed to the ground G; and the wheel 23, which is rotatably attached to the support member 22 extending above the fixed block 21 to abut the support groove 3. surface.

[0035]The groove 3 is longer in the front-rear direction, and is the left and right wall portions 32, 32 extending upward from the bottom wall 31 and from the left and right ends of the bottom wall 31 (infigure 2 In the middle, only the upper opening type of the wall portion is shown) is configured to have a substantially Japanese character shape when viewed from the front-rear direction.

[0036]The drive unit 4 is mounted to the fixing portion 5 fixed at the ground G. The fixing portion 5 includes a longer rectangular and plate-shaped plate member 51 in the front and rear directions, which support the driving portion 4; and 4 blocks of legs 52, 52, 52, 52 (infigure 2 In the middle, only the left and right direction is shown), the four angles of the support plate member 51.

[0037]Specifically, the driving portion 4 includes a motor 41 as a drive source, which is driven by a power source 6; a rotating member 42 which is a rotating member 42 as a returning member, which belongs to the rotation of the drive shaft 41a from the electric motor 41. The force is supported around the drive shaft 41a in a constant speed cyclone, and the conversion mechanism 43 is provided between the rotating member 42 and the groove 3, move the rotation of the rotating member 42 (moving on the circle) The rotation movement is converted into a straight line reciprocating movement of the groove 3. As the electric motor 41, for example, an inexpensive general-purpose motor such as an induction motor or a motor such as a gear mechanism such as a gear mechanism is combined with these inexpensive universal motors. In the case where the combined reducer, the appropriate speed of the specification of the vibration conveyor can be obtained, and the torque required for the driving of the vibration conveyor can be easily obtained.

[0038]The electric motor 41 includes a motor main body 41b and a drive shaft 41a protruding from the motor body 41b. Further, the motor main body 41b is fixed to the state of which is fixed to the lower surface of the plate member 51, and the drive shaft 41a penetrates from the upper end of the plate member 51 to the upper end of the plate member 51. The rotary member 42 can be mounted integrally in the protruding upper end portion of the drive shaft 41a.

[0039]The conversion mechanism 43 is disposed between the upper surface of the plate member 51 and the lower surface of the bottom wall 31 of the recess 3. Specifically, the conversion mechanism 43 includes: the swing member 431, which is configured to connect the rotating member 42 by means of a pin P1 shaft support, and can be circumtesting the intermediate portion 431c between one end portion 431a and the other end portion 431b. A shaft 8 (refer to the shaft 8 (refer to) by the drive shaft 41a of the axis of the axis of the rotating member 42 (refer tofigure 1 Swing; and the connection member 432, one end portion 432a supports the other end portion 431b coupled to the swing member 431 by means of pin P2 shaft, and the other end portion 432b is supported by means of pin P3 shaft supporting the bottom wall 31 fixed at the groove 3. The rectangular shape and the plate-shaped fixed plate 7. Further, a link mechanism coupled to the electric motor (driving source) 41 and the recess 3 is configured by the rotating member 42 and the conversion mechanism 43. The recess 3 reciprocates the recess 3 by using the conversion mechanism 43 to convert the rotational force of the rotating member 42 that rotates with a constant speed into a straight reciprocating motion. Thereby, not only the high-priced servo motor is not required as the drive source, but also the drive, the controller, the controller, in addition to this, can not be required to drive the circuit, the control circuit. In addition, since it is a mechanical structure, the cause of the fault is easily carried out, and the repair response to the field is easy to perform.

[0040]The shaft 8 is configured by the shaft body 82 and the roller 83, the shaft body 82 protrudes upward from the upper end of the upper surface of the plate member 51, which is protruded from the upper end of the upper surface of the plate member 51, and the roller 83 rotates freely to the axis main body. 82.

[0041]The swing member 431 is formed of a plate-shaped member formed as a rounded plate shape from the respective corners of the two end portions, and is kept in the longitudinal direction, and, in the direction of the retaining roller 83. Slide sliding portion 431g. The sliding portion 431g is a long hole formed by the swing member 431, allowing the swing member 431 to move relative to the shaft 8, so that the length direction of the wiped member 431 and the distance between the end portion 431a and the shaft 8 in the longitudinal direction of the swing member 431 The ratio of the distance between the end portion 431b and the shaft 8 changes with the rotation of the rotating member 42. Thus, by sliding the swing member 431 by using the sliding portion 431G, the ratio of the distance between the longitudinal direction between the length direction of the swing member 431 and the shaft 8 and the distance between the other end portion 431b between the swing member 431 and the shaft 8 changes smoothly. Performance. Further, only by forming a long hole in the swing member 431, it is possible to constitute the sliding portion 431g, so the production of the wobble member 431 is easy.

[0042]Further, the swing member 431 is configured to move in the following manner that the linear reciprocating motion of the groove 3 is inversion from one direction to the other direction (in the direction of the conveying direction), by means of the connection member 432 Compared with the driving force transmitted by the groove 3, the driving force transmitted to the groove 3 to the groove 3 in one direction (conveying direction) is larger than the driving force in one direction (conveying direction). Therefore, the acceleration ratio acting on the recess is inverted from the other direction to the recess to the recess when inversion from one direction to the other direction. Moreover, the movement can be implemented in a mechanical structure.

[0043]The connecting member 432 is composed of a plate-shaped member formed of a substantially rectangular shape and the respective corners of the two ends, which is configured to be slightly smaller than the width of the swing member 431 and the length is slightly longer than the length of the swing member 431, but Not limited thereto.

[0044]The left and right rotating rollers 9, 9 are disposed before and after the left and right ends of the fixing plate 7, and the fixing plate 7 moves in a straight line in the front-rear direction. Each rotary roller 9 is rotatably embedded in an axis 10 fixed at the ground G.

[0045]Then, based onimage 3 (A),image 3 (B) andFigure 4 (A),Figure 4 The schematic diagram shown in (b) illustrates the movement of the conversion mechanism 43 when the workpiece is transported by the vibration conveyor 1.

[0046]First, explanationimage 3 (A),image 3 (B) andFigure 4 (A),Figure 4 (B), the first section (reference festival) 11 is part of the set (mounting) electric motor 41, equivalent tofigure 2 Plate member 51. The second section 12 is a member that constitutes a rotation pair of drive shafts 41a with the electric motor 41, which is equivalent tofigure 1 The rotating member 42 coupled to the drive shaft 41a. The third section 13 is a member that constitutes a rotation pair with the second section 12, which is equivalent tofigure 1 The wobble member 431 is coupled to the rotating member 42 by the pin P1. The fourth section 14 is a member that constitutes a sliding (slide) pair of sliding (Slide) of the third section 13 and is a member (e.g., a cylindrical member) that allows the swing member 431 to be swimped to be attached to the first section 11. Therefore, the fourth section 14 hasfigure 1 The same function is the same as the long hole (sliding portion 431g) formed by the swing member 431. The fifth section 15 is a member that constitutes a rotation pair with a third section 13, which is equivalent tofigure 1 Connecting member 432. The sixth section 16 is a component that constitutes a rotating pair with the fifth section 15, which is equivalent tofigure 1 Fixed plate 7. Further, the third section 13 and the fifth section 15 are coupled by the pin P2, and the sixth section 16 and the fifth section 15 are connected by the pin P3. Further, the drive shaft 41a of the electric motor 41 is disposed on the first section 11, and the swing fulcrum 17 will be described later and the pin P3 as a joint portion of the sixth section 16 and the fifth section 15 are disposed.

[0047]If the electric motor 41 is driven,image 3 (A), the second section 12 is rotated in the counterclockwise direction indicated by the arrow during top view. Due to the rotation of the second section 12, the third section 13 is moved to the second section 12 side (left) while swinging. Since the movement of the third section 13, the fifth section 15 is pulled, pulling the Section 6 16 and moves in a straight line along the first section 11. Thereby, the groove 3 moves to the left side (seeimage 3 (A) ~image 3 (B)). If the second section 12 is further rotated,Figure 4 (A), the second section 12 is swinging the third section 13 to move the third section 13 while swinging the third section 13 in a direction opposite to the direction. Thereby, the groove 3 moves from the left side to the right (seeFigure 4 (A) ~Figure 4 (B)).

[0048]In the vibration conveyor 1 of the above structure, in the case where the recess 3 is retrofled from the forward advancement, the amount of operation between the input and output is relatively retrofitted in the case where the recess 3 is reversed from the backward advancement. The ratio of the amount of action input is changed. Description This point isimage 3 In the case where the inversion of the rearward advancement is reversed, the input of the third section 13 is smaller than the input of the second section 12 relative to the driving electric motor 41, and the operation of the third section 13 is small. The reason is that the swing fulcrum from the third section 13 (equivalent tofigure 1 The shaft body 82) 17 to the distance L2 of the pin p2 as the connecting portion of the third section 13 and the fifth section 15 from the pin P1 to the third section 13 as the second section 12 and the third section 13 13 The distance L1 of the swing fulcrum 17 is short (from the principle of the lever).

[0049]Relative to this,Figure 4 In the case where the forward backward retrofit is reversed, the input of the third section 13 is larger than the input of the second section 12 relative to the driving electric motor 41, and the operation of the groove side end (output) of the third section 13 is large. It is because the swing fulcrum 17 from the third section 13 to the distance L2 of the pin P2 of the third section 13 and the fifth section 15 is from the second section 12 and the third section 13. The distance L1 of the swing P1 to the third section 13 13 (from the principle of the lever). Thus, the change in the conversion rate of the amount of operation between the input and the output is caused by a lever ratio that is caused by the position change of the swing fulcrum 17 with respect to the position of the third section 13.

[0050]Therefore, in the case where the groove 3 is retrofled from the forward advancement, the output relative to the input is large, and thus the reversal of the forward direction rearward is rapidly performed. That is to say, the acceleration (deceleration) when inversion is large. On the other hand, when the groove 3 is inversely reversed from the backward direction, the output relative to the input is smaller, and therefore, the reversal of the backward advancement is slowly performed. That is, the acceleration (deceleration) when inversion is inverted. Further, the maximum value of the acceleration (deceneration) of the recess 3 when the forward-backward reverse rotation is larger than the value of the gravity acceleration between the workpiece and the groove 3, thereby between the workpiece and the groove 3 Slide. Since it is sliding generated when the forward rearward reversal, the workpiece is relative to the groove 3 relative to the groove 3. As described above, the sliding workpiece generates a sliding workpiece in the case of the movement of the moving body, while the deceleration is relative to the groove 3 relative to the groove 3 relative to the groove 3. On the other hand, the groove 3 is ushered in the inversion of the forward direction after the backward movement is performed, and the acceleration motion of the forward direction is welded. As a result, the speed at which the groove 3 is consistent with the speed of the workpiece, and the static friction is functioning. In the case where the groove 3 is reversed from the backward advancement, the acceleration is small compared to the case where the forward rearward is reversed, and therefore, there is no slide between the groove 3 and the workpiece, and the static friction is to be subjected to static friction. Side of action is integrated. The grooves are repeated to move such a movement to deliver the workpiece toward the front.

[0051]It can also be configured to adjust the swing fulcrum of the drive shaft 41a and the third section 13 of the electric motor 41 (equivalent tofigure 1 The distance between the shaft main body 82) 17. Thereby, the motion mode (size of the acceleration) of the recess 3 can be changed, and the motion of the groove is preferably adjusted to optimal depending on the characteristics of the workpiece.

[0052]

[0053]In the first embodiment, the plate member 51 of the support driving portion 4 is fixed to the structure of the leg 52 provided on the ground G, thereby driving the reaction to drive the vibration conveyor 1, but can be set to more Simple structure. On the other hand, in the second embodiment, the reaction force when driving the vibration conveyor 1 is difficult to transmit to the ground. Specifically, it is, for example,Figure 5 As shown, a plurality of abutting support plate members 51 from below (specifically, four of the four angles disposed on the panel member 51) support 18. Each of the bearing 181 includes a fixed block 181, which is fixed to the ground G; and the wheel 183 rotatably mounted about the horizontal axis X1, which is attached to the support member 182 extending above the fixed block 181, against the support groove 3 surface. Further, a balance weight 19 is mounted in the lower surface of the plate member 51.

[0054]By such a support plate member 51, the plate member 51 can be moved in a direction opposite to the operation of the recess 3 relative to the ground, with respect to the surface of the recess, and the reaction force transmitted from the plate member 51 to the ground is reduced. The amount of operation of the plate member 51 depends on the ratio of the sheet member 51 and the recess 3, and thus the balance weight 19 may be provided in order to obtain a balance between the weight of the recess 3. Further, the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

[0055]

[0056]It can also be, such asFigure 6 As shown, the vibration conveyor 1 shown in the second embodiment is provided as an elastomeric spring (here a coil spring, but may be a coil spring, a leaf spring, etc.) 20. Specifically, the front end of the rear end and the plate member 51 fixed to the front side of the surface G is coupled to the front end and the front end of the front side of the surface G in the front and rear direction (horizontal direction), and the front and rear directions are utilized. (Horizontal Direction) Spring (Coil Spring) 20 will be coupled to the rear end of the front end and the plate member 51 of the rear side of the ground G. By configuring the spring 20, the plate member 51 has a recoverable force to a predetermined central position, and when the vibration conveyor 1 is driven, the plate member 51 and the groove 3 are reciprocated centered at a predetermined position. Further, the same reference numerals as those in the second embodiment are labeled, and the description thereof will be omitted.
