Description

  The present invention relates to an advance / retreat apparatus, and more particularly, an advance / retreat apparatus that advances and retracts a molded product gripping tool mounted on a molded product take-out machine mounted on a resin molding machine in parallel and linearly to a mold surface. It is about.

  Conventionally, an advance / retreat apparatus suitable for advancing and retracting a molded product gripping tool mounted on a molded product take-out machine mounted on a resin molding machine in parallel and linearly with a mold surface has been proposed. (For example, FIG. 9 of patent document 1).

  As shown in FIGS. 7 and 8, the advance / retreat apparatus described in Patent Document 1 includes an air cylinder device 100, and includes a cylinder 100a, a piston 100b, and a piston rod 100c. For example, a sandwich-type molded article gripping tool 101 is attached. Further, the cylinder 100 a is mounted at a predetermined position of the molded product take-out machine 103 via the mounting position setting mechanism 102.

  According to the advancing / retreating device, the air cylinder device 100 is driven by air pressure, and the piston 100b and the piston rod 100c are moved up and down, so that the molded product gripping tool 101 is parallel to the mold surface (not shown) and straight. Can be moved up and down. Therefore, if the molded product take-out machine 103 is of a swivel type as shown in FIG. 9 of Patent Document 1, the swiveling motion of the air cylinder device 100 by the molded product take-out machine 103 and the molded product take-out machine 103 By controlling the respective movements while maintaining the relative relationship of the three movements, that is, the contact / separation movement that causes the air cylinder device 100 to approach or separate from the mold surface and the lifting / lowering movement of the piston rod 100c by the air cylinder device 100 The molded product held on the mold surface can be gripped by the molded product gripping tool 101, taken out of the machine, and received. In addition, if the molded product take-out machine 103 is of a traverse type, a reciprocating motion for linearly moving the air cylinder device 100 by the molded product take-out machine 103 into and out of the resin molding machine, and an air cylinder device 100 by the molded product take-out machine 103 are used. By controlling the respective movements while maintaining the relative relationship of the three movements, that is, the approaching / separating movement that causes the air cylinder device 100 to move closer to or away from the mold surface and the lifting / lowering movement of the piston rod 100c by the air cylinder device 100, The held molded product can be gripped by the molded product gripping tool 101, taken out of the machine, and stored.

JP 2000-190260 A.

  For example, the operation of gripping the molded product held on the mold surface with the molded product gripper 101 is performed by holding the air cylinder device 100 in a vertical posture. For this reason, the height from the floor surface to the top of the air cylinder device 100 is considerably increased. A large resin molding machine is generally equipped with a large molded product take-out machine 103. Since the large molded product take-out machine 103 is equipped with a long air cylinder device 100, an air cylinder device is provided from the floor surface. The height to the top of 100 is further increased. Therefore, depending on the scale of the molding factory, the height dimension from the floor surface to the top of the air cylinder device 100 is limited. In such a case, the limitation of the height dimension is cleared by making an adjustment for lowering and positioning the air cylinder device 100 using the mounting position setting mechanism 102.

  On the other hand, although the height dimension from the floor surface to the top of the air cylinder device 100 is not limited, the molded product gripping tool 101 is held on the mold surface even when the piston 100b and the piston rod 100c are extended to the lower end of the stroke. Even when a molding condition occurs in which the molded product does not reach the position of the molded product and the molded product is held on the mold surface further below the position of the molded product gripping tool 101, the mounting position setting mechanism 102 is the same as described above. By using this, the air cylinder device 100 is lowered and positioned to make it possible to grip the molded product. In some cases, the air cylinder device 100 may be raised and positioned.

  By the way, the attachment position setting mechanism 102 includes one clamping portion 102A, the other clamping portion 102B, and a plurality of bolts 102C. The one clamping portion 102A is directly or partially shown on the outer peripheral surface of the cylinder 100a. An arc-shaped concave portion 102a that abuts indirectly via an elastic liner (not shown) is formed, and an elastic liner (not shown) or the like is provided directly on a part of the outer peripheral surface of the cylinder 100a or the like in the other holding portion 102B. An arcuate recess 102b that abuts indirectly is formed, and one clamping portion 102A is fixed to the molded product take-out machine 103 side. Accordingly, the arc-shaped recess 102a and the arc-shaped recess 102b are brought into contact with a part of the outer peripheral surface of the cylinder 100a in a state of facing each other, for example, passing through the other clamping portion 102B and passing through the other clamping portion 102A. By screwing and tightening a plurality of bolts 102C, the cylinder 100a can be clamped by one clamping part 102A and the other clamping part 102B, and the air cylinder device 100 can be positioned at a predetermined mounting position.

  In the advancing / retreating device having the mounting position setting mechanism 102 having such a structure, the screwing of the plurality of bolts 102C is loosened, and the clamping of the cylinder 100a by the one clamping part 102A and the other clamping part 102B is released. After that, the cylinder 100a is raised or lowered, and a plurality of bolts 102C are screwed and tightened at this position, whereby the air cylinder device 100 can be positioned at a predetermined mounting position.

  The clamping force of the cylinder 100a generated by screwing the plurality of bolts 102C is applied to the cylinder 100a from the one clamping part 102A and the other clamping part 102B. However, since the cylinder 100a of this type of air cylinder device 100 does not require a high pressure resistance, its thickness is set to be relatively thin. For this reason, the cylinder 100a may be elastically deformed or plastically deformed in the radial direction by screwing the plurality of bolts 102C, and the roundness may be impaired. If the roundness of the cylinder 100a is impaired, the operation of the air cylinder device 100 is hindered and the molded product cannot be taken out. Therefore, there is a drawback that adjustment of the screwing torque of the plurality of bolts 102C necessary for positioning the cylinder 100a at a predetermined position in a state where the roundness of the cylinder 100a is maintained is complicated.

  The present invention solves such a problem, and an object of the present invention is to advance and retract which can be positioned at a predetermined mounting position in a state where no malfunction occurs without requiring complicated adjustment. To provide an apparatus.

The present invention is an advance / retreat apparatus in which a cylinder of a cylinder device is attached to a molded product take-out machine via an attachment position setting mechanism.
The attachment position setting mechanism comprises a displacement guide portion provided integrally with the cylinder to guide the displacement of the cylinder, it is incorporated in the displacement guide portion Rutotomoni, given the advancing and retracting device is mounted on the molded article take-out machine A holding mechanism for positioning at the mounting position ,
The displacement guide portion comprises a plurality of grooves provided in parallel to each other in a uniform cross section over the entire length of the cylinder.
The holding mechanism is fixedly attached to each of the plurality of short strips fitted into the displacement guide, the mounting plate attached to the molded product take-out machine, and the plurality of short strips. A plurality of bolts protruding toward the back of the part and penetrating the mounting plate,
By tightening the nuts screwed to these bolts, the back surface of the displacement guide part is pressed against the front surface of the mounting plate to keep the displacement guide part from moving forward and backward. The guide portion is configured to be capable of advancing and retreating .

According to this, the holding force of the holding mechanism, because only loaded into the cylinder displacement guide portion provided integrally with the cylinder is not loaded, even if a large holding force is applied to the displacement guide portion, the larger The cylinder does not elastically or plastically deform due to the holding force. Therefore, it is possible to avoid malfunctions reciprocating the movable portion of the cylinder device by deformation of the cylinder is prevented, the holding force of the holding mechanism, the displacement guide portion may be a magnitude above the level that can be held in a fixed position It will be. That is, the advancement / retraction apparatus can be positioned at a predetermined mounting position without causing a malfunction even if the holding force is roughly adjusted without complicated adjustment.

  According to the present invention, since the holding force of the holding mechanism necessary for setting the mounting position of the movable portion to a predetermined position is not less than a level at which the displacement guide portion can be held at the predetermined position, complicated adjustment is required. Even if the holding force is roughly adjusted without using the above, the advancing / retreating device can be positioned at a predetermined mounting position without causing a malfunction.

Hereinafter, an embodiment of an advance / retreat apparatus according to the present invention will be described with reference to the drawings.
1 is an overall front view showing an embodiment of an advance / retreat apparatus according to the present invention, FIG. 2 is a left side view of FIG. 1, FIG. 3 is an enlarged cross-sectional view taken along the line AA in FIG. It is a BB arrow line view. In these drawings, the advance / retreat apparatus 1 comprises an air cylinder apparatus 2, and is incorporated into an elongated cylinder 3 having a vertical axis having a function as a fixed portion, and the cylinder 3 is kept airtight and can be advanced and retracted. A piston 4 that functions as a movable part and a piston rod 5 having a base end attached to the piston 4, and a lower end portion (tip portion) of the piston rod 5 that always protrudes outside the cylinder 3 A sandwich-type molded product gripping tool 6 is attached in a vertical posture, and this molded product gripping tool 6 is configured to be openable and closable and posture-changeable by first and second drive mechanisms (not shown).

  In the air cylinder device 2, a cylinder 3, which is a fixed portion, is attached to a predetermined position of a molded product take-out machine 8 included in a production machine via an attachment position setting mechanism 7.

  The mounting position setting mechanism 7 has a uniform cross-section over the entire length of the cylinder 3 at the back of the cylinder 3 and is provided at a predetermined position on the molded product take-out machine 8 with a displacement guide portion 70 formed of a pair of grooves provided integrally. A holding mechanism 9 that is mounted and incorporated in the displacement guide part 70 and can selectively hold the displacement guide part 70 in a displacement-permitted state or a non-displaceable state is provided.

  That is, the holding mechanism 9 is fitted into a pair of grooves constituting the displacement guide portion 70 and allows the displacement guide portion 70 to move up and down in the vertical axis direction, that is, to allow the cylinder 3 as a fixed portion to move up and down. A short strip 90, a plurality of (for example, four) bolts 91 that are fixed in the vicinity of both ends in the vertical direction of each short strip 90 and project horizontally toward the back of the displacement guide portion 70, and molding A mounting plate 92 that is mounted at a predetermined position of the article take-out machine 8 and the rear surface of the displacement guide portion 70 contacts and separates, and a plurality of (for example, four) bolt insertion holes 93 provided horizontally on the mounting plate 92 are passed through. And a tightening nut 94 that is screwed onto the front end portion of the bolt 91 with the front end portion of the bolt 91 protruding from the back surface of the mounting plate 92.

  According to the advancing / retreating device 1 having the above-described configuration, the air cylinder device 2 is driven by air pressure, and the piston 4 and the piston rod 5 are moved up and down, so that the molded product gripping tool 6 is parallel to a mold surface (not shown) Can be raised and lowered linearly. Therefore, if the molded product take-out machine 8 is a known swivel type, the swiveling motion of the air cylinder device 2 by the molded product take-out machine 8 and the air cylinder device 2 by the molded product take-out machine 8 approach the mold surface or By controlling each movement while maintaining the three-way relative relationship between the contacting / separating movement for separating and the piston rod 5 lifting movement by the air cylinder device 2, the molded article held on the mold surface is molded. It can be gripped by the gripping tool 6, taken out of the machine, and received. Further, if the molded product take-out machine 8 is a known traverse type, the reciprocating motion for linearly moving the air cylinder device 2 by the molded product take-out machine 8 in and out of the resin molding machine, and the air cylinder by the molded product take-out machine 8 By controlling each movement while maintaining a three-way relative relationship between a contact / separation movement for moving the apparatus 2 close to or away from the mold surface and a lifting / lowering movement of the piston rod 5 by the air cylinder device 2, the mold surface is controlled. The molded product held in the container can be gripped by the molded product gripping tool 6, taken out of the machine, and stored.

  By firmly tightening the plurality of tightening nuts 94, the back surface of the displacement guide portion 70 is pressed against the front surface of the mounting plate 92 of the holding mechanism 9, and the displacement guide portion 70 is held in a state where it cannot be moved up and down. The displacement of the device 2 in the vertical axis direction is restrained, and the air cylinder device 2 can be positioned at a predetermined mounting position. In addition, by loosening the tightening of the plurality of tightening nuts 94, the pressure contact of the rear surface of the displacement guide portion 70 with respect to the front surface of the mounting plate 92 is released, and the displacement guide portion 70 is held in the up-and-down displacement allowable state. After the device 2 is moved up or down toward the selected mounting position, the air cylinder device 2 can be positioned at the selected mounting position by strongly tightening a plurality of tightening nuts 94 at this position.

  On the other hand, the holding force of the holding mechanism 9, that is, the holding force substantially proportional to the tightening torque of the plurality of tightening nuts 94 is a displacement provided integrally with the cylinder 3 via the plurality of bolts 91 and the pair of short strips 90. Since it is loaded only on the guide part 70 and not on the cylinder 3, even if a large holding force is loaded on the displacement guide part 70, the cylinder 3 will not be elastically deformed or plastically deformed by this large holding force. . For this reason, since the disadvantage that the piston 4 and the piston rod 5 are prevented from moving back and forth due to the deformation of the cylinder 3 can be avoided, the tightening torque of the plurality of tightening nuts 94 is larger than a level at which the displacement guide portion 70 can be held at a predetermined position. That's fine. Therefore, even if the holding force is roughly adjusted without the need for complicated adjustment, the air cylinder device 2 can be positioned at a predetermined mounting position without causing a malfunction.

  In the above embodiment, the displacement guide portion 70 of the attachment position setting mechanism 7 is provided in a uniform cross section over the entire length of the cylinder 3 at the back of the cylinder 3, so that the displacement guide length of the displacement guide portion 70 is 3 can be enlarged corresponding to substantially the entire length. Therefore, the positioning adjustment range of the air cylinder device 2 can be expanded.

  Further, since the advance / retreat apparatus 1 is constituted by the air cylinder device 2, the structure of the advance / retreat apparatus 1 can be simplified, and the advance / retreat speed can be increased to contribute to the improvement of work efficiency.

  In the above-described embodiment, the air cylinder device 2 composed of a single rod cylinder is used which projects the piston rod 5 from the cylinder 3 downward in one direction and moves up and down (advances and retreats). However, the advancing / retreating device 1 according to the present invention is not limited to the above-described embodiment. The advancing / retreating is performed by projecting the piston rod 5 from the cylinder 3 in two vertical directions. The air cylinder device 2 including both rod cylinders to be used may be used, and the molded product gripping tool 6 may be attached to the tip portion of the piston rod 5 protruding downward. Further, an air cylinder device 2 composed of a rodless cylinder is used, and a lifting member (advancing / retracting member) is attached to a slider that moves up / down (advancing / retreating) outside the cylinder following the piston moving up / down (advancing / retreating) within the cylinder. The structure which attached the molded article holding tool 6 to the lower end part (tip part) of the raising / lowering member may be sufficient. When using such a rodless cylinder, it goes without saying that the mounting position setting mechanism 7 is provided in a cylinder that functions as a fixed portion. Further, a linear motor that moves forward and backward is used, and the mounting position setting mechanism 7 is provided on the fixed side member to constitute the forward / backward device 1, and the movable side member of the linear motor is followed by the outside of the fixed side member. The structure which attached the molded article holding | gripping tool 6 to the lower end part (front-end | tip part) of the raising / lowering member (advancing / retreating member) to raise / lower (advance / retreat) may be sufficient.
