Description

[Detailed explanation of the idea] This idea relates to a chain conveyor that transports shafts and the like.

Such a chain conveyor is known from Japanese Patent Laid-Open No. 59983/1983.

This is a system in which two casings, each of which is circulated by a check 7 with a support member for the shaft attached to a link, are erected at a distance slightly shorter than the length of the shaft to be transported.

Therefore, shafts shorter than this interval cannot be transported, and two casings are required in which the checker 7 circulates, making manufacturing time-consuming.

Therefore, the present invention has a vertically erected housing and two endless chains stretched between the rooks installed above and below both side walls of the housing, and a chain between the links of both chains. Fix the connecting plates at predetermined intervals in the length direction of the
Both arms 1 are placed on the surface of each connecting plate with the shaft, etc. placed horizontally.
At the same time, attach a U-shaped mounting piece with 5 to the above-mentioned housing, and install a carrying board on the side where both chains will face upwards, on which the shafts etc. are placed horizontally on both arms of the mounting piece, and both chains are lowered. In a chain conveyor that transports shafts, etc., in which the shafts, etc. are scooped up and transferred from both arms of the placing piece on the side, and the transport plates are attached at an angle with respect to the horizontal, the above-mentioned housing is attached to the central piece and from both edges of the central piece. Two opposing U-layer plates each having a U-shaped cross section with leg pieces protruding in the same direction are fixed with a distance between them, and the center of each U-layer plate is fixed. Each of the above-mentioned connections is made up of bolts with one piece serving as a side wall, and a guide plate extending in the vertical direction is fixed at each interval between the opposing leg pieces of both the U-layer plates by the bolt, and a mounting piece is fixed to the surface. It is characterized in that a sliding shoe is attached to the back surface of the plate for slidingly contacting the guide plate.

Therefore, according to the present invention, only one housing is required, and
Although it cannot carry objects that are shorter than the distance between the arms of the placement piece, it can carry objects that are much shorter than the known conveyor described above.

Furthermore, when both chains move up and down, the connecting plate, which is attached between the links of both chains and has the above-mentioned mounting piece fixed to its surface, slides into contact with the surface of the guide plate fixed to the housing with the sliding shoe attached to the back side. Both chains do not swing, and therefore objects to be transported such as shafts placed on the mounting piece are prevented from falling from the mounting piece.

Embodiments of the present invention will be described below with reference to the drawings.

In Figs. 1 to 3, reference numeral 1 denotes a vertically erected housing, which consists of a central piece and two opposing U-shaped housings each having a U-shaped cross section with leg pieces protruding in the same direction from the periphery of the central piece. It consists of bolts 3 that fixed both U-layer plates 2, 2 with a space between the shape plates 2, 2 and their leg pieces, and each central piece of the above-mentioned U-layer plates is attached to both sides of the mounting 1. form a wall.

Then, as is well known, rooks are installed above and below both side walls of the housing 1, and two endless chains 74 and 4 are stretched between the rooks, and both chains are tensioned by a tensioning device 9. In this embodiment, the lower rook is rotationally driven by a motor and a belt transmission device, and both chains 4, 4 are circulated.

Connecting plates 6 are fixed between the links of both chains 4, 4 at equal intervals in the longitudinal direction of the chain.On the surface of each connecting plate 6 is a mounting piece 5 having U-shaped arms on which a shaft or the like is placed horizontally. Install.

A vertical guide plate 8.8 is fixed to the bolt 3 of the housing 1, and is located between the legs of the U-shaped plates 2, 2, and is fixed between the links of both chains 4, 4. A sliding shoe 7 is attached to the back surface of each connecting plate 6, which slides on the surfaces of the guide plates 8, 8 when the chino circulates up and down, and prevents the chino from swinging as it circulates. To prevent.

Each piece 15 of the above-mentioned mounting plate 5 has a wide bay-shaped mouth formed by a long jaw 19.20 on one side and a short jaw 19.20 on the other side, facing each other at a distance in the vertical direction as shown in FIGS. It is a provision.

That is, this bay-shaped mouth has inclined surfaces 21.22 on opposite sides of the jaws 19.20 that are inclined in opposite directions, and each of the above-mentioned inclined surfaces 21.
．． 22, arcuate surfaces 23.23 having the same curvature above and below, and a straight surface 24 vertically connecting the arcuate surfaces 23.23.
Therefore, the length of the shorter jaw 20 measured from the straight plane 24 is equal to the diameter of the curvature of the arcuate surface 23, while the length of the longer jaw 19 is equal to S. It is 8 times more.

The mounting piece 5 has the longer jaw 19 of both arms at the bottom on the ascending side of the chain, and reverses and the shorter jaw 20 is at the bottom on the descending side. It is attached to each connecting plate 6 so that it becomes like this.

The housing 1 includes a carry-in station 14 consisting of a carry-in plate 13 that slopes diagonally downward toward the chain on the side where both chains 4, 4 go up, and a carry-out station 14 that consists of a carry-out plate 18 that slopes diagonally downward from the chain on the side where both chains 4, 4 descend. Station 17 is the installation.

The carry-in plate 13 is placed between both arms 15, 15 of the mounting piece 5 with the shaft 12 placed horizontally on the longer jaw 19, and the carry-out plate 18 is placed between the arms 15 and 15 of the shorter one. The shaft 12 lying above the jaws 20.20 is scooped out and rolled out according to the inclination.

Of course, the loading plate 13 is placed on the protruding part of the longer jaw 19 that protrudes beyond the short jaw 20, with the shaft 12 horizontally, so that the protruding part passes in the vertical direction. A slit may also be formed.

This allows the long jaws 19 of both arms of the loading plate 5 to be moved from the carrying plate 13 to the loading plate 5.
The shaft 12, which is supplied between the protruding parts of the housing, falls into the back of the bay-shaped mouth and rises together with the chains 74 and 4, and when both chains turn around the rook at the upper end of the housing, it is short. It rides lying down on one of the jaws 20, descends together with the chess 74 and 4, is scooped up by the carry-out plate 18, and descends.

When both chains ascend or descend, the sliding shoes 7 on the back of the connecting plate 6 with the mounting plate attached to the surface slide against the vertical guide plate 8 integrated with the housing 1, so that the chain 7 The shaft 12, which does not swing and is placed horizontally on the mounting plate, will not fall.

In order to axially support the shaft 12 carried by the chains 74, 4, each U-layer plate 2.2 constituting the housing is provided with a handrail-shaped guiding rod 16 facing each end face of the shaft with a slight play. (FIGS. 1 and 3), or a U-shaped plate 25 may be attached outside the multi-arm 15 of the mounting piece 5 (FIG. 5).

Further, it is preferable to cover the area below the carry-in station 14 in the ascending area of the check 74.4 and the area below the carry-out station 17 in the descending area with a cover 11 for safety.

FIG. 6 shows another example of the chain conveyor of this invention for conveying a stepped shaft 26, taken in section at the height of the loading station.

This chain conveyor is similar to the apparatus shown in FIGS. 1-3, except for the loading and unloading stations, so like parts are given the same reference numerals.

The loading or unloading station is shown here as an inclined rail consisting of two plate members 27, with suitable members 2
8 to fix it to the housing.

The spacing between the plate members 27 can be quickly adjusted by loosening the nut 29 to match the length of the shaft 26 to be transported.

For this purpose, a slot 30 is provided on each side of the spacer fixed to the plate member 27.

Similarly, the guide rod 16 can be adjusted to the length of the shaft 26 to be transported by means of suitable means, such as a slot 31 made in the fixed plate and a nut 32, by loosening the nut, so that the shaft 26 cannot be moved in the axial direction. be adjustable.
