Abstract

PROBLEM TO BE SOLVED: To halve a moving distance of a stretching rod to enable downsizing of a casing apparatus, by attaching a container holder to a tip of a string fixed to a base and hooking the string on a wheel at a tip of the stretching rod fixed to the base. SOLUTION: A base 21 reciprocates on a belt 10 and on a roller conveyer 9 along a rail 20 by a driving means. An air cylinder 25 is fixed upward to the base 21, while a wheel 27 is attached to a tip of its piston rod 26. A base end of a chain 16 wound around the wheel 27 is fixed to the base 21, while holders 3, 3 of a container 2 are fixed to a tip. When the piston rod 27 is vertically stretched, the holders 3, 3 rise/lower in conjunction with rotation of the wheel 27. The rod 26 need be stretched in a half length of a rising/lowering distance of the desired holders 3, 3 since a length of the chain 17 wound around the wheel 21 is changed on both sides.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to mounting a device for lifting and lowering a container gripper on a base that reciprocates in a space between a container transport path and a case transport path, and transports a predetermined number of transported containers on the case transport path. To a caser that is moved to and stored in a case.

[0002]

2. Description of the Related Art In this type of caser, a container filled with drinking water, liquor, beer, etc. is lifted up by a gripper, transferred to a case transport path as it is, and lowered into an empty case to store the container. It is supposed to. FIG.
FIG. 3 is a schematic view for explaining a vertically moving state of a gripper of a conventional caser, in which an air cylinder 5 is fixed to a base 1 which reciprocates in a space on a conveyance path of a container and a conveyance path of a case (not shown); 2 is moved up and down by the expansion and contraction operation of the piston rod 6 of the air cylinder 5. The swing of the gripper 3 is suppressed because it is guided by the guides 4 and 4. However, no matter how the transport path surface of the container 2 and the transport path of the case 7 are designed, they are indicated by (a) and (b). As described above, it is necessary to raise and lower the gripper 3 at a distance larger than the height of the container 2 to the case 7, and to expand and contract the piston rod correspondingly. The piston rod is required to have strength according to the weight and length to be moved, and a large air cylinder must be installed to make the caser itself compatible with various types of containers, which makes the caser itself large-scale There are inconveniences.

[0003]

[Technical problem] The present invention is to mount a device for lifting and lowering a container gripper on a base which reciprocates in a space between a container transport path and a case transport path, and transports the transported containers by a predetermined number of cases. An object of the present invention is to provide a caser that is moved on a road and stored in a case so that the moving distance of the gripper can be ensured even if the moving distance of the telescopic rod for operating the gripper is reduced by half.

[0004]

Technical means for solving this technical problem include (a) attaching a wheel to the distal end, fixing a vertically expandable rod to the base, and (b) mounting the base end on the base. (C) hanging the strip with the container holding tool attached to the front end thereof on a wheel, and operating the rod to raise and lower the tool.

[0005] Since the container gripper is attached to the distal end of a strip having a base end fixed to the base, and the strip is hung on a wheel attached to the tip of a telescopic rod fixed to the base, When the telescopic rod expands and contracts in the vertical direction, the gripper moves up and down as the wheel expands and contracts. The expansion and contraction of the rod changes the length of the strip hung on the wheel on both sides, so that the gripper moves twice as long as the movement distance of the wheel. Therefore, the expansion and contraction of the rod may be performed at a half of the desired lifting / lowering distance of the gripper.

The transport path of the container and the transport path of the case may be run in parallel. However, when the transport path of the case passes through the lower part of the container transport path outside the front end of the container transport path, the gripped container is not lifted up once but is held as it is. The case can be moved laterally to face the case conveyance path. In the latter case, the container transport path and the case transport path may be arranged in two stages up and down so that the case transport path may appear at the end of the container transport path, or may traverse the front end of the container transport path. Alternatively, a case transport path may be arranged. The telescopic rod may have a function that can expand and contract in the vertical direction, and can be used for air-scilling and hydraulic cylinder piston rods, racks that can be operated with pinion gears, and other known rods with telescopic mechanisms. Can be attached. In addition, other than a chain, a wire, a rope made of natural fiber or synthetic fiber can be used as the strip. What is necessary is just to change the form of a wheel suitably according to the kind of a strip.

[0007]

As described above, the moving distance of the gripping tool can be secured even if the moving distance of the telescopic rod for operating the gripping tool is reduced by half.
There is an advantage that the telescopic rod can be stabilized in its extended state, and the lifting and lowering operation of the gripper can be stabilized. Further, since it is not necessary to make the extendable rod long, there is an advantage that the caser can be reduced in size and the case can be packed in a narrow place.

1 and 2 are plan views of a transfer path of a container 2. FIG. The containers 2, 2 are conveyed by double conveyor belts 10, 10 running in the direction of the arrow on both sides of the partition wall 12. By rotating the feed blades 11 intermittently in front of the tip of the belt 10, the containers 2 The vehicle moves forward at a constant interval (see FIG. 1). The rotation of the feed blade can be controlled by an electric signal while detecting the state of transport of the container 2 and the movement of the case. When the containers 2 and 2 reach the tip of the belt 10, the support plate 14 moves forward on the belt 10 from the left and right. An uneven piece 15 made of rubber protrudes from the entire surface of the support plate 14 to maintain the distance between the containers 2 and 2 without damaging them and to restrict the movement thereof.
In this state, it is desirable to temporarily stop the belt 10, but since the movement of the container 2 is surely restricted, the belt may be kept running.
In addition, the uneven piece uses a mountain-shaped thing, so that it can respond even if the thickness of the container changes, but if it is not necessary to respond to the change in thickness, Square-shaped or semi-cylindrical uneven pieces may be used.

In this embodiment, a case conveyance path and a case conveyance path are arranged in two stages, and a case conveyance path appears at a place where the container conveyance path ends. , The container 2, which has reached a certain distance
2 is housed in the case 7 through the steps of FIGS.
A guide rail 20 is supported by a frame 22 so as to extend between a front end portion of the belt 10 and a roller conveyor 9 for conveying a case that appears in front of the belt 10. The base 21 reciprocates on the belt 10 and the roller conveyor 9 along the rails 20 by driving means (not shown). An air cylinder 25 is fixed upward on the base 21, and a wheel 27 is attached to a distal end portion of a piston rod 26.

The base end of the chain 16 wrapped around the wheel 27 is fixed to a base 21, and the grippers 3 of the container 2 are fixed to the end. This gripping tool 3 is a support plate 17
Are fixed in parallel to the lower surface of the support plate 17, and the guide rods 18 attached to the four corners of the support plate 17 pass through the guides 24 arranged on the base 21, so that the support plate 17 moves up and down while maintaining a horizontal state. Can be. Note that the gripper 3 may have any known configuration as long as it has a function of lifting a heavy container filled with liquid or the like.

At the stage where the movement of the containers 2 and 2 is restricted at the leading end of the belt 10 while maintaining the interval, the piston rod 26
Is slightly lowered to lower the gripper, and after engaging the upper end of the container, the base 21 is advanced along the rail 20 (see FIG. 4 → FIG. 5). The case 7 is advanced to be positioned directly below the containers 2 and 2, and at that stage, the piston rod 26 is lowered to store the containers 2 and 2 in the case 7 (see FIG. 5 → FIG. 6). Next, the piston rod 26 is extended,
To return to the original position.
