Description

[Detailed explanation of the idea] <Industrial application field> This invention relates to a rod filling guide.

<Prior art> Conventionally, as a guide for filling a rod housed in a cylinder into a container using a piston, the
As described in Japanese Patent No. 59-29481, there was one that was formed of a gently tapering cylindrical body with a long longitudinal section.

<Problem that the invention aims to solve> However, in the conventional guide for filling rods, when the rod passes inside, the tip of the guide is pushed out and the problem occurs.
The drawback was that the rod could get caught between the widening cracks, preventing the piston from filling.

There was also the problem that the rod protruding from between the widening cracks could pierce the soft container.

<Means for Solving the Problems> The present invention to solve the above-mentioned problems uses a tapered taper provided coaxially on the extrusion side of the cylinder 15 into which a large number of rods 4 are inserted and converged. The piston 35 moves the rod 4 in the cylinder 15 to the guide 10 through the cylindrical guide 10.
In this device, the guide 10 is attached to a cylindrical peripheral wall from the proximal end toward the distal end so that the distal end side is elastically pushed open by the insertion of the rod 4. It used to be composed of an outer guide 7 having each formed split 7c, and a thin cylindrical inner guide 9 similarly having a split 9c, and the split 9c of the inner guide 9 was replaced by the split 7c of the outer guide 7.
It is characterized in that the inner guide 9 is inserted and held within the outer guide 7 so as to be out of phase with respect to the inner guide 9.

<Operation> The tip of the guide 10 is inserted into the container 37, and the rod 4, which is converged by the cylinder 15, is pushed out by the piston 35. At this time, the guide 10 guides the rod 4 inside the container 37, but the splits 7c and 9c of the outer guide 7 and the inner guide 9 are expanded, and the diameter of the tip of the guide 10 is expanded. Since the outer guide 9 and the inner guide 7 are out of phase with each other, the inner guide 9 covers the split 7c of the outer guide 7, and the rod 4 is prevented from being caught.

<Example> An example of the present invention shown in the drawings will be described below.

As shown in FIG. 2, a base 2 is placed on a pair of parallel rails 1 so as to be movable on the rails 1 via sleeves 2a provided at the four corners of the lower surface.

A guide holding plate 3 is vertically installed on the front end of the base 2, and as shown in FIG.
A circular insertion opening 5 through which the holder is inserted is bored in the front-rear direction. A guide 10 is fastened to the peripheral edge of the front opening of the insertion port 5 with bolts or the like.

As shown in FIG. 3, the guide 10 has a tapered frustum shape and is composed of an outer guide 7 and an inner guide 9.

The outer guide 7 is formed into a truncated cone shape as a whole by attaching a single unit in which a base end plate 7b is formed laterally on the base end portion of a guide piece 7a whose cross section is formed in the shape of a 1/4 circular arc, combined in a circular manner. A split 7c is formed between the single bodies.

The outer guide 7 is made of plastic or the like having a certain degree of elasticity. Also, the proximal plate 7
A concave portion 7d for accommodating the base end portion 9b of the inner guide is formed in a concentric arc shape on the inside of b.

The inner guide 9 has a number of guide pieces 9a each having an arcuate cross section corresponding to the number of guide pieces 7a of the outer guide 7, and a split 9c is provided between each guide piece 9a, and the base of the guide piece 9a is The end portion 9b is bent outward so as to engage with the recess 7d, and is provided with a plurality of notches to enable the guide piece 9a to curve.

The inner guide 9 is formed by connecting and cutting out a number of trapezoidal pieces corresponding to the number of individual outer guides 7 from a thin metal plate such as stainless steel having a certain elasticity, and joining the ends together.

The inner guide 9 formed in this way is inserted into the outer guide 7 with each split 7c, 9c out of phase, as shown in FIG.
The base portion 9b in d is fastened and fixed by the outer guide 7 and a packing 11 formed in a circular ring shape according to the shape of the outer guide base plate 7b.

By being configured as described above, even if the tip of the guide 10 is spread outward when the rod passes inside, the guide piece 9a of the inner guide 9 will not fit into the split 7c of the outer guide 7. Since they overlap, the rod 4 will not be caught in the split 7c.

A cylinder stand 13 is erected behind the guide holding plate 3 on the base 2, and a cylinder 15 is attached to the upper end of the cylinder stand via a fulcrum 14. As shown in FIG. 4, the cylinder 15 is constructed by abutting cylinder pieces 15a and 15b each having a semicircular arc cross section, and each cylinder piece rotates about the fulcrum 14 so as to be openable and closable. The rotation of the cylinder pieces is carried out by raising and lowering the opening/closing cylinder 18 via a cylinder arm 16 provided on one cylinder piece 15a, and the rotation of the other cylinder piece 15b is carried out via a gear or the like (not shown). , is performed in response to the movement of the cylinder piece 15a. The cylinder 15 is opened and closed by the rotation of each of these cylinder pieces.

Above the cylinder 15 is a V-shaped opening/closing bucket 17 with both sides curved inward.
It is provided so as to accommodate the rod 4 in the axial direction of the rod 5 . The bucket bag 17 consists of bucket bag pieces 17a and 17b that open and close left and right, and the upper end of each bag bag piece is rotatably supported by pins 19a and 19b. One bucket piece 17a swings open and close around a pin 19a by a cylinder 23 via an arm 21, and at the same time, the other bucket piece 17b also swings in a symmetrical direction via a transmission means such as a gear (not shown). As a result, the lower end of the opening/closing bucket 17 is opened and closed.

Inside the bucket, a control plate 25 is connected to a rotation shaft 27.
The swinging action of the rod body 4 has the effect of aligning the received postures of the rods 4 transferred by the conveyor 29 in the axial direction of the cylinder 15.

As shown in FIG. 1, a transparent acrylic plate 31 is attached to the front side of the opening/closing bucket 17.
The back and forth movement of the rod 4 is restricted and visual confirmation is possible.

As shown in FIG. 2, a piston stand 33 is erected behind the cylinder stand 13 on the base 2.
A piston 35 is slidably supported on the upper part thereof. Since the piston 35 has the function of pushing out the rod 4 inside the cylinder 15, the diameter of the piston is the same as the inner diameter of the cylinder 15 in the closed state, and the piston 35 slides to the vicinity of the tip of the guide 10. Therefore, the guide 10, insertion hole 5, cylinder 15, and piston 35 described above are arranged so as to be located on the same axis.

A pair of parallel rails 59 are provided in front of the base 2 so as to be perpendicular to the rails 1, and a support plate 39 is mounted via a sleeve 57 that slides on the rails 59. The support plate 39 is equipped with a support piece 41 for supporting the container 37 from below, and a fixing piece 53 for fixedly supporting the container 37 from above.

The support piece 41 is a semi-cylindrical body consisting of a pair of cylindrical pieces having a 1/4 arc-shaped cross section in order to correct the external shape of the soft container 37 to a regular arc, and both ends are rotatably supported by pins. . One of the support pieces 41a is swung by the engagement of gears 45 and 43 due to the oscillation of an arm 49 that is raised and lowered by a cylinder 51. The other supporting piece 41b is supported by swinging in a symmetrical direction with the swinging of the supporting piece 41a through a transmission means such as a gear, similar to the opening/closing mechanism of the cylinder 15 and opening/closing bucket 17 described above. The piece 41 is released downward.

Furthermore, the fixing piece 53 slides toward the center of the cross section of the container 37 by a fixing cylinder 55 attached to the support plate 39, and presses and fixes the container 37 placed on the support piece 41 from above. be.

If such a container holding mechanism is provided separately, there is no need to lengthen the guide 10 in order to hold the container 37, and a short guide with a very short split can be used, which prevents the rod 4 from being caught in the split. The probability of this occurring also decreases.

To explain the operation of the apparatus according to the embodiment of the present invention constructed as described above, the container 37 is held on the support plate 39 by the support piece 41 and the fixing piece 53, and moved on the rail 59. 37 is positioned on the axis of the guide 10, cylinder 15, etc.

Next, the bucket 17 is opened and closed by the conveyor 29.
The rod 4 is conveyed inside. Conveyance of the conveyor 29 is stopped when the number of rods conveyed reaches a predetermined number.
A control plate 25 swings within the opening/closing bucket 17 to align the rod 4 in the axial direction of the cylinder 15. When a predetermined amount of rods 4 are accumulated in the opening/closing bucket 17, the cylinder 15 is released by the cylinder 18, and when the opening/closing bucket 17 is then released, the rods 4 aligned by the control plate 25 are released. is dropped and accommodated in the cylinder 15.

After the cylinder 15 is closed and the rod 4 is completely accommodated, the base 2 is slid forward and the tip of the guide 10 is inserted into the container 37. When the piston 35 is pushed forward here, the rod 4 in the cylinder 15 is stored in the container 37 while being converged by the guide 10. The rod 4 is completely enclosed in the container 37.
When the base 2 is moved back and the support piece 41 is released, the container 37 filled with the rod 4 is released.
falls and is sent to the next process.

In addition, during the operation of sending the rod 4 to the next process by the piston 35, the conveyor 2 is placed on the opening/closing bucket 17.
It is possible to adopt a configuration in which the rod 4 falling from the rod 9 is accommodated, and in this case, it is useful for shortening the takt time.

<Effects of the invention> In the guide of the present invention constructed as described above, the inner guide expands while covering the split of the outer guide, so it is possible to prevent the rod from getting caught in the split and prevent the spread of the split. The drawback of the stick protruding from the container breaking through the container is also completely eliminated.
