Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention involves plating small parts (materials) inside the plating bath while rotating or inverting them at a predetermined angle. The present invention relates to a mounting structure for the lid of a plating barrel.

"Prior Art" A conventional lid mounting structure for a plating barrel will be explained with reference to FIGS. 8 and 9.

For example, a polygonal cylindrical body 1 made of a water-permeable material such as a perforated synthetic resin plate is provided, and end plates 2 made of synthetic resin are fixed to both ends of this body 1 to form a barrel. . 11 is a reinforcing bone, 21 is a rotating shaft, and one end plate 2 is formed into a gear for transmitting rotational force from a drive source (not shown).

The upper surface of the body 1 is opened to provide a rectangular opening 3 for taking materials in and out, a lid receiving flange 31 is formed on the inner peripheral edge of this opening 3, and a lid receiving flange 31 is formed on one opposite side of the opening 3. Edge members 4, 4 are provided that stand up from the outer edge of the opening 3, and a lid 5 is placed on the lid receiving flange 31 to close the opening 3.

The lid 5 is composed of a lid frame 51 made of synthetic resin and a mesh or perforated plate 52 stretched over the window portion of the lid frame, and the lid 5 is held down by a plurality of lid holders 6.

Each lid holder 6 is plate-shaped, and its center is screwed to a screw 61 rotatably mounted on the lid frame 51, and both ends 60, 60 are connected to locking holes 41 formed in the edge members 4, 4. , 41 and turn the screw 61 in a certain direction, the screw 61 presses the lid frame 51 (lid 5) against the lower lid receiving flange 31.

When removing the lid 5 from the opening 3 in order to take in and take out materials (not shown), loosen the screw 61, turn the lid holder 6 to one side, and connect both ends 60, 60 to the locking hole 41,
41 and lift the lid 5 upward.

``Problem to be solved by the invention'' The conventional lid mounting structure described above has a structure in which the lid holder 6 is pushed against the edge members 4, 4 by screws 61, and the lid 5 is pressed against the lower lid receiving flange 31. Because of this, the lid 5 is deformed so that the periphery is warped and the center is lowered, and this deformation not only causes the lid 5 to wobble during operation, but also creates a gap between the lid 5 and other members, which can cause damage to the lid 5. There is a problem that small plating materials tend to become clogged.

Further, according to the above structure, the lid presser 6 is attached to the edge materials 4, 4.
Since a plurality of screws 61 must be provided in a state where they are passed over, the area of the lid frame 51 for attaching the screws 61 is required to be large, and the area of the perforated plate 52 becomes relatively narrow, so that the plating efficiency decreases accordingly. Also,
When the rotation of the barrel is stopped and the barrel is lifted out of the plating bath, the barrel does not necessarily stop with the lid 5 on top, so if the area of the liquid-permeable material of the lid 5 is small, water will not drain from the barrel. becomes worse and reduces work efficiency.

An object of the present invention is to provide a mounting structure for a plating barrel lid that solves the above-mentioned problems.

"Means for Solving the Problem" In order to achieve the above-mentioned object, the present invention provides a barrel for plating as described above, in which a lid presser is arranged to slide onto both sides of the lid along the respective edge materials. A plate is provided, and each lid holding plate is provided with an appropriate number of protrusions that protrude in the direction of the rim material, and the rim material is provided with a suitable number of projections that protrude in the direction of the rim material. The projection of the plate is guided in a state where it is prevented from floating upward, and the projection is allowed to float from the edge material when the lid holding plate is slid to the other side along the edge material. The present invention adopts a means for providing an insertion portion and fixing each lid holding plate to the lid or edge material in a state in which the protrusion is guided to the insertion portion.

Each lid holding plate can be fastened to the lid or edge material with screws or the like.

"Operation" According to the lid mounting structure according to the present invention, when the lid holding plate is slid to one side along the edge material and the protrusion provided on the lid holding plate is guided to the insertion part provided on the edge material, When the lid holding plate is fixed to the lid or the edge material, the lid cannot be removed from the edge material, and the opening of the barrel is maintained in a closed state.

In this manner, when the lid is closed, no downward pressure is applied to the lid, especially to the central portion of the lid, so the lid is hardly deformed, and various problems caused by deformation are prevented.

In addition, since the lid holding plate is not installed across both edge materials, the area of water-permeable parts such as the mesh or perforated plate of the lid can be made relatively large, making plating more efficient. As well as improving drainage, drainage performance also becomes better.

"Embodiment" A preferred embodiment of the mounting structure according to the present invention will be described with reference to FIGS. 1 to 7.

FIGS. 1 to 3 are examples.

Reference numeral 1 denotes a polygonal cylindrical body, which is formed into a hexagonal cylindrical shape by combining water-permeable materials such as perforated synthetic resin plates with numerous small holes through reinforcing ribs 11 at each corner. A basket is constructed by bonding circular end plates 2 to both ends. One of the end plates 2 at both ends also serves as a gear for receiving rotational force from a drive source (not shown), and a perforated plate may also be used for both end plates 2. In addition to the case where a perforated plate as described above is used for the body part 1, there is also a case where one side of the perforated plate is covered with a net.

The body 1 is provided with an opening 3 whose entire upper surface is open as shown in FIG. 2 in order to take in and out plating material (not shown), and a lid receiving flange 31 is provided on the inner peripheral edge of this opening 3. The lid 5 is placed on the lid receiving flange 31 like a dropped lid and attached as described below.

The lid 5 includes a lid frame 51 made of a blind board made of synthetic resin, and a perforated plate (or mesh) stretched over the window hole of the lid frame 51.
52, the lid frame 51 and the lid receiving flange 31 in contact with the lid frame 51 are formed with concave-convex fitting portions 32 so as to fit into each other as shown in FIG. It is configured so that there are no gaps between them.

On the opposite side in the longitudinal direction of the opening 3, an end plate 2 is provided at both ends in a state rising from the outer edge of the lid receiving flange 31.
Edge members 4, 4 fixed to the rim are provided.

Lid holding plates 7, 7 made of synthetic resin are provided on both sides of the lid 5 in the longitudinal direction so as to slide along the corresponding edge members 4, 4, respectively. In this embodiment, a long hole 71 parallel to the edge material 4 is formed at a suitable location in each lid holding plate 7, and a screw-shaped guide pin 72 standing upright on the lid frame 51 is guided into this long hole 71. By attaching nuts 73 to pins 72, each lid holding plate 7 slides along the corresponding edge material 4 without separating from the lid 5.

Each lid holding plate 7 has an appropriate number of protrusions 8 formed in the direction of the corresponding edge material 4, and the corresponding edge material 4 has an appropriate number of protrusions 8, which are enlarged in FIGS. 2 and 3. As illustrated in FIG. 2, when the lid holding plate 7 is slid to one side, the protrusion 8 is guided to a non-floating state, and when the lid holding plate 7 is slid the same distance to the other side, the protrusion 8 is inserted so that it can float. A section 9 is provided. When sliding the lid holding plate 7 to one side, it is preferable that the projection 8 be guided while lightly contacting the inner upper surface of the insertion portion 9.

In this embodiment, a shaft 7a having a head shaped like a bolt 7b is erected in the center of a lid frame 51 extending across the center, and a drive gear 7d integrated with a handle lever 7c is rotated to this shaft 7a. Install freely,
By turning the handle lever 7c, the rotation of the drive gear 7d passes through the intermediate pinion gear 7e attached to the lid frame 51, and then to the rack portion 74 formed so as to face the center portion of the lid holding plate 7.
, and each lid holding plate 7 slides along the edge material 4.

A handle lever 7c integrated with the drive gear 7d
In this case, a retaining nut 7f is screwed onto the bolt 7b of the shaft 7a to prevent its free rotation, so that the protrusion 8 of the lid retaining plate 7 is inserted into each insertion portion as shown in the figure. When the retainer nut 7f is tightened while the lid retainer plate 7 is guided into the insertion portion 9, each lid retainer plate 7 is secured to the lid 5 so that the protrusion 8 formed thereon does not escape from the insertion portion 9, and the lid 5 is opened. It is in a state where it cannot be removed from part 3.

In addition, in the state shown in Figure 7, if the presser nut 7f is loosened and the handle lever 7c is slightly turned counterclockwise, the upper lid presser plate 7 in the figure will move to the right, and the lower lid presser plate 7 will move to the right. The lids slide to the left in the same figure, and the protrusions 8 of each lid holding plate 7 come out of their respective insertion portions 9, and the lid 5 becomes in a state where it can be lifted upward in FIG. 2 and removed.

The mounting structure of the above embodiment is such that the lid holding plates 7 on both sides are slid to guide each protrusion 8 into the corresponding insertion portion 9, and in this state, the lid holding plates 7 are fixed to the lid 5 so as not to move. Therefore, no force is applied to the lid 5 that would cause it to easily deform, and the deformation of the lid 5 is almost eliminated.

Therefore, the life of the lid 5 can be maintained for a long time, and the area of the perforated plate 52 of the lid 5 can be made wider than in the conventional structure, improving the plating efficiency and improving the drainage of the barrel.

In the embodiment described above, the insertion part 9 is formed in a groove shape when viewed from the front in FIG. 3, but it is not formed in a groove shape but in a state where it is cut out from the front side to the back side of the edge material 4 in FIG. 3. It can also be implemented even if the illustrated insertion portions 9 are continuous in the longitudinal direction of the edge material 4.

Further, the inner upper surface of the insertion portion 9 is formed into a tapered shape as shown in FIG. It can be configured to enter into the insertion portion 9 in a wedge shape.

Furthermore, the hook-shaped guide 9 is formed by adhering a suitable L-shaped piece or the like to the upper surface of the edge material 4, as shown in FIG. This can also be carried out by forming it in a floating state.

In the embodiment described above, the lid holding plates 7, 7 are slid in symmetrical directions by a gear mechanism consisting of a drive gear 7d with a handle lever 7c, a pinion gear 7e, a rack part 74, etc., but the drive gear 7d
may be directly connected to the rack portion 74, or the lid holding plates 7, 7 may be slid separately by hand without using such a gear mechanism, and the lid holding plates 7, 7 may be connected to one of the elongated holes 71 guided by the lid holding plates 7. It is also possible to implement a structure in which the lid holding plate 7 is fixed to the lid 5 by tightening the nut 73 of the guide pin 72.

6 and 7 show another example of a mechanism for sliding the lid holding plate 7, in which a shaft 7a is formed in a screw shape at the center of the lid frame 51 in the center of the lid 5 as shown in FIG. is erected, a handle lever 7c is rotatably attached to this shaft 7a, and both lid holding plates 7, 7 are attached.
Guide pins 75 are set up on the top surface as shown in FIG. 7, and both ends of the handle lever 7c are overlapped with the lid holding plate 7, and each guide pin 75 is guided into the elongated hole 7g at both ends of the handle lever 7c. , shaft 7a
A presser nut 7f is screwed from the upper end of the holder.

The other configurations of this embodiment are the same as those shown in FIGS. 3 to 3, and in FIG. Each lid holding plate 7 is tightened by tightening the nut 7f.
It is in a state where it is fixed on the lid 5.

In the state shown in Figure 6, when the retainer nut 7f is loosened and the handle lever 7c is rotated clockwise, the upper lid retainer plate 7 in the figure moves to the right, and the lower lid retainer plate 7 in the figure moves to the left. Each slides, and each protrusion 8 comes out of its respective insertion part 9 and becomes floating from the edge member 4, and when the lid 5 is lifted, it comes off from the barrel.

The effects of this embodiment are also similar to those of the previous embodiment.

In each of the above embodiments, instead of the configuration in which the lid pressing plate 7 is fixed to the lid 5 with the protrusion 8 of the lid pressing plate 7 guided to the insertion part 9 of the edge material 4, when the lid pressing plate 7 is fixed to the edge material 4, the third Upper part 4 of insertion part 9 illustrated in FIGS.
From a, for example, the lid retaining plate 7 may be configured to be fixed to the edge material 4 by screwing in a push screw (not shown) and pressing the protrusion 8 into the insertion portion 9, or, for example, by using a suitable elastic force (not shown). This can also be carried out by pressing the protrusion 8 guided into the insertion section 9 against the inner upper surface of the insertion section 9 using the body or the like.

Further, the body portion on the polygonal cylinder is not a regular polygonal cylinder as shown in the figure, but may be a modified polygonal cylinder.

"Effects of the invention" According to the lid mounting structure according to the invention, when the lid is attached to the opening, almost no pressing force is applied to the lid, so the deformation of the lid is almost eliminated and durability is improved. In addition, it is possible to prevent a decrease in plating efficiency due to deformation of the lid and other adverse effects, and the area of the water-permeable portion of the lid can be made wider, which improves plating efficiency and drainage of the barrel.
