Description

  The present invention relates to a belt take-out device for taking out an endless belt from a feeder portion, and a belt conveying system including the belt take-out device.

  When manufacturing a belt such as a transmission belt including a V-belt, a plurality of belts having a rectangular cross section are formed by cutting a belt sleeve obtained by molding and vulcanization at a predetermined width (perpendicular cut). There is a case. For example, the plurality of belts are hooked on a horizontally extending shaft-like feeder portion and aligned along the longitudinal direction of the feeder portion. Then, the most distal belt among the plurality of belts is taken out from the feeder portion by the belt take-out device. Then, a V-belt having a substantially trapezoidal cross section is formed by applying a bias cut that cuts both side surfaces of each belt into a bias shape (see, for example, Patent Documents 1 to 3).

  The bias cut is, for example, a process of cutting both side surfaces of the belt by rotating the pair of cutting blades in a state where the belt is wound around the pair of rollers (belt traveling unit) and rotated. Thereby, both side surfaces of the belt are formed in a tapered shape. That is, the triangular cross section of both side surfaces of the belt is cut, and the cut portion is removed as endless cut waste. The operation of inserting the belt into the bias cut device and the operation of taking out the V belt and cut waste after the bias cut from the bias cut device are performed manually.

  On the other hand, a configuration is known in which article transportation at a factory is automatically performed by a robot (see, for example, Patent Documents 4 and 5).

Examples of such V belts include V belts used in power transmission applications such as general industrial machines and automobiles. More specifically, examples of the V belt include a wrapped V belt, a low edge V belt, and a V-ribbed belt.

  The manufacturing apparatus 1 turns the belt 101 into a V-belt 102 by cutting both side surfaces of the belt 101 in the width direction W of the belt 101 having an endless annular shape and a rectangular cross section in an inclined manner. The belt 101 and the belt 102 may be collectively referred to as “belt 100”.

  The gantry 2a is provided to support the feeder arm 2b and a belt pressing portion 202 described later. The gantry 2a is formed using, for example, a metal plate or the like. In the present embodiment, the gantry 2a is formed in an L shape in a side view. And the feeder arm 2b is extended from the intermediate part of the part extended in the up-down direction of the mount frame 2a.

  The feeder arm 2b is provided to hold a plurality of (one drum) belts 101 in a suspended state. The feeder arm 2b is formed in a shaft (beam) shape extending linearly in the horizontal direction. The feeder arm 2b is cantilevered by the mount 2a. Specifically, the base end (base) of the feeder arm 2b is fixed to the gantry 2a by welding or the like.

  The feeder arm 2b has an arm base 2c and a pair of convex strips 2d, 2d.

  The arm base 2c is a member that extends in the longitudinal direction of the feeder arm 2b, and is formed in, for example, a quadrangular prism shape. A pair of ridges 2d, 2d are fixed to the upper part of the arm base 2c. Each protrusion 2d, 2d is a member extending in the longitudinal direction of the feeder arm 2b, and is formed in, for example, a quadrangular prism shape. A gap SP is formed between the pair of ridges 2d, 2d. This gap SP is provided as a portion into which a take-out portion 203 of the belt chuck 201 described later is inserted.

  When the belt 101 is suspended from the feeder arm 2b, the inner peripheral surface of the upper end portion of each belt 101 is received by each of the convex strip portions 2d and 2d. The belt 101 held on the feeder arm 2 b is sent to the biaxial stretching device 3 by the belt conveyance system 6.

  FIG. 3A is a side view of the biaxial stretching device 3. FIG. 3B is a front view of the biaxial stretching device 3. Referring to FIGS. 1, 3A and 3B, the biaxial stretching device 3 is provided to elongate the belt 101 along a predetermined longitudinal direction (vertical direction in the present embodiment). It has been.

  The biaxial stretching device 3 includes a support column 3a, a main shaft 3b, and a sub shaft 3c.

  The support column 3a extends upward from the ground and supports the main shaft 3b and the sub shaft 3c. The main shaft 3b and the sub shaft 3c are provided as portions where the inner peripheral portion of the belt 101 is hung. The main shaft 3b and the sub shaft 3c extend from one side surface of the column 3a and are arranged in parallel to each other. The auxiliary shaft 3c is supported by the support column 3a via a drive mechanism (not shown), and is relative to the support column 3a in a direction in which the auxiliary shaft 3c and the main shaft 3b face each other (vertical direction in the present embodiment). Displaceable. Thereby, the sub-shaft 3c can be displaced in a direction approaching the main shaft 3b (upward direction) and a direction away from the main shaft 3b (downward direction).

  The belt 101 stored in the feeder unit 2 is supplied to the main shaft 3b and the sub shaft 3c using a belt chuck 201. At this time, the distance between the main shaft 3b and the sub shaft 3c is shortened by arranging the sub shaft 3c closer to the main shaft 3b. In this state, the belt chuck 201 places the belt 101 on the main shaft 3b. Next, the sub shaft 3c is displaced downward. Thus, the belt 101 is stretched and bent by the main shaft 3b and the sub shaft 3c, and has a shape elongated in the longitudinal direction (vertical direction).

  The belt 101 is conveyed to the bias cutting device 4 by using the insertion hand 21 of the belt conveyance system 6. When the belt 101 is transferred from the biaxial stretching device 3 to the insertion hand 21, the auxiliary shaft 3 c is displaced toward the main shaft 3 b and releases the tension applied to the belt 101. As a result, the belt 101 is deformed so as to swell in the horizontal direction from a vertically elongated shape, and is sandwiched between the insertion hands 21.

  FIG. 4 is a side view of the bias cut device 4. Referring to FIGS. 1 and 4, the bias cutting device 4 cuts both end portions in the width direction of the belt 101 in an inclined shape, thereby forming a cross-sectional shape of the belt 101 (a shape in a cross-section perpendicular to the circumferential direction of the belt 101). ) To be V-shaped. The bias cutting device 4 is an example of a “cutting device that cuts the side surface of the belt to make the belt a V-belt”. The bias cut device 4 is adjacent to the biaxial stretching device 3 and is arranged around the main displacement mechanism 20 of the belt conveying system 6 together with the feeder unit 2 and the biaxial stretching device 3.

  The bias cut device 4 includes a base 4a, a main shaft 4b, a sub shaft 4c, a cutter 4d, and a cut waste pushing portion 4e.

  The base 4a extends upward from the ground, and supports the main shaft 4b, the sub shaft 4c, the cutter 4d, and the cut waste pushing portion 4e. The main shaft 4b and the sub shaft 4c are provided as portions on which the inner peripheral portion of the belt 101 (V belt 102) is hung. The main shaft 4b and the sub shaft 4c extend from one side surface of the base 4a and are arranged in parallel to each other. The sub shaft 4c is supported by the base 4a via a drive mechanism (not shown), and is relative to the base 4a in the direction in which the sub shaft 4c and the main shaft 4b face each other (vertical direction in the present embodiment). Displaceable. Thereby, the sub-shaft 4c can be displaced in a direction approaching the main shaft 4b (upward direction) and in a direction away from the main shaft 4b (downward direction).

  The main shaft 4b and the sub shaft 4c are formed in a cylindrical shape. An annular groove is formed in each of the intermediate portion of the main shaft 4b and the intermediate portion of the auxiliary shaft 4c, and the belt 101 is hung on these grooves. As a result, the belt 101 is held in a stable posture by the main shaft 4b and the sub shaft 4c.

  As described above, the belt 101 from the biaxial stretching device 3 is supplied to the main shaft 4 b and the sub shaft 4 c using the insertion hand 21 of the belt conveyance system 6. At this time, the distance between the main shaft 4b and the sub shaft 4c is shortened by arranging the sub shaft 4c closer to the main shaft 4b. In this state, the insertion hand 21 places the belt 101 on the main shaft 4b. Next, the sub shaft 4c is displaced downward.

  Thus, the belt 101 is stretched and bent by the main shaft 4b and the sub shaft 4c, and has a shape elongated in the longitudinal direction (vertical direction). The main shaft 4b is rotated by an electric motor (not shown). The belt 101 stretched between the main shaft 4b and the sub shaft 4c is cut by the cutter 4d.

  The cutter 4d is provided in order to cut both side surfaces of the belt 101 in a state of being tensioned by being hung on the main shaft 4b and the sub shaft 4c. The cutter 4d is attached to an actuator (not shown), for example, and can be displaced to a position where both side surfaces of the belt 101 are cut and a position separated from the belt 101. The cutter 4d cuts both side surfaces of the belt 101 by coming into contact with both side surfaces of the belt 101 that is rotationally driven by the main shaft 4b and the sub shaft 4c.

  As a result, the belt 101 becomes the V belt 102. Further, endless cut waste 103 is generated on both sides of the V belt 102 in the width direction W of the belt 101. The cross-sectional shape of the cut waste 103 (the shape of the cut waste 103 in a cross section orthogonal to the longitudinal direction of the cut waste 103) is a triangular shape. The V belt 102 and the cut waste 103 are transported to the discharge unit 5 using the take-out hand 22 of the belt transport system 6.

  When the V belt 102 and the cut waste 103 are transferred from the bias cutting device 4 to the take-out hand 22, the auxiliary shaft 4c is displaced toward the main shaft 4b and releases the tension applied to the V belt 102. As a result, the V-belt 102 is deformed so as to swell in the horizontal direction from the vertically elongated shape and is sandwiched between the take-out hands 22. Moreover, the cut waste 103 is transferred from the bias cutting device 4 to the take-out hand 22 by the cut waste push-out portion 4e pushing out the cut waste 103 to the take-out hand 22 side. For example, the cut waste pushing portion 4e is disposed adjacent to the main shaft 4b and supported by the base 4a.

  The cut waste pushing portion 4e is formed using, for example, an air cylinder device, and has a movable portion 4h. The movable portion 4h extends substantially parallel to the main shaft 4b and can be moved forward and backward with respect to the base 4a.

  When the movable portion 4h is displaced so as to protrude from the base 4a, the cut waste 103 is pushed out from the main shaft 4b. In this way, the V-belt 102 and the cut waste 103 are transferred from the bias cutting device 4 to the take-out hand 22 and then conveyed to the discharge unit 5.

  FIG. 5 is a side view of the discharge unit 5.

As a result, the belt 101 is pressed against the pressure pieces 35 a to 35 d and is held by the insertion hand 21.

  Further, the second receiving portion 38 of the belt gripping mechanism 36 moves forward to the biaxial stretching device 3 side by the operation of the belt gripping mechanism actuator 41. As a result, the belt 101 is gripped by the first receiving portions 37 of the belt gripping mechanism 36 and the corresponding second receiving portions 38. That is, the belt 101 is held by both the pressure unit 35 and the belt gripping mechanism 36, and is prevented from dropping from the insertion hand 21. Next, as shown in FIG. 19C, the insertion hand 21 is displaced so as to retract from the biaxial stretching device 3 by the operation of the main displacement mechanism 20. Referring to FIG. 19C and FIG. 20, at this time, as described above, the belt 101 is elongated in the vertical direction as a result of being held by the pressurizing unit 35 and the belt gripping mechanism 36, and is also in the vertical direction. The intermediate portion of the belt 101 is bent inward in the radial direction of the belt 101. In the present embodiment, the belt 101 is held in a figure 8 shape in the insertion hand 21. Thereby, the belt 101 is held by the insertion hand 21 with a high holding force.

  The insertion hand 21 is conveyed to the bias cut device 4 by the operation of the main displacement mechanism 20 as shown in FIG. Referring to FIG. 21A, the main displacement mechanism 20 inserts the insertion hand 21 into the bias cut device 4 in a state where the main shaft 4b and the sub shaft 4c are close to each other. Accordingly, the belt 101 is disposed so as to surround the main shaft 4b and the sub shaft 4c of the bias cut device 4.

As a result, as shown in FIG. 21B, the belt 101 is given a tension by the main shaft 4b and the sub shaft 4c, and has an elongated shape. Thereby, the belt 101 is released from contact with the pressure pieces 35a to 35d of the pressure unit 35, and the holding of the belt 101 by the pressure unit 35 is released.

  Thereafter, as shown in FIG. 21C, the main displacement mechanism 20 retracts the insertion hand 21 so as to be separated from the bias cut device 4. In this state, the bias cut device 4 performs a bias cut process on the belt 101.

  Next, the main displacement mechanism 20 rotates the bracket support portion 31 so that the take-out hand 22 faces the bias cut device 4 from the state where the insertion hand 21 faces the bias cut device 4. Then, as shown in FIG. 22A, the main displacement mechanism 20 inserts the take-out hand 22 into the bias cut device 4.
