Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can container transporting device which can grasp and hold an ear portion of a can container and can be easily transported through a carriage.

[0002]

2. Description of the Related Art A round can-shaped container typified by a drum can is lightweight and durable, but it is extremely difficult to handle because it has no clue when it is manually carried.

[0003] Therefore, conventionally, there has been proposed a can-shaped container carrying device which can hold a can-shaped container in an upright posture and can be easily carried through a trolley. This one has a pair of upper and lower jaw members and a lifter that drives the jaw members mounted on a trolley with casters, and the jaw members operate by operating the lifters so that the body of the can-shaped container and the lid plate are separated from each other. The can-shaped container can be lifted by grasping the protruding portion formed in a ring shape at the joint, that is, the so-called ear portion from above and below. In addition,
The jaw members are connected at their rear end portions and intermediate portions via auxiliary link members to form a four-bar link as a whole. Further, the tip portion of the upper jaw member is gently bent downward. The lifter is connected to the auxiliary link member at the rear end, and the front ends of the jaw members can be closed by simultaneously driving the rear parts of the upper and lower jaw members.

[0004]

According to the prior art, since the jaw member forms a four-bar link together with the auxiliary link member, the overall structure is complicated, and the upper and lower jaw members are vertically arranged. Due to the rocking motion, the gripping operation of the can-shaped container with respect to the ear portion is uncertain, and there is a risk that the can-shaped container may slip during transportation.

In view of the problems of the prior art, the object of the present invention is to form a complicated structure by connecting the upper jaw member directly to the lifter and connecting the lower jaw member to the lifter via the upper jaw member. An object of the present invention is to provide a transporting device for a can-shaped container, which has a simple structure and which can always realize a stable gripping operation by eliminating the 4-bar linkage.

[0006]

The structure of the present invention for achieving the above object is a trolley, and a pair of upper jaw members mounted on the trolley so as to be vertically movable, and engaging with the ears of a can-like container.
A lower jaw member, an upper jaw member, and a lifter for driving the lower jaw member.The upper jaw member has a rear end portion connected to the lifter, an intermediate portion connected to the lower jaw member, and is directed toward the lower jaw member. The gist is to form a hook that bends at an acute angle at the tip.

The hook may be provided with a pressing tip corresponding to the width of the lower jaw member at the tip.

Further, the upper jaw member may be provided with a spring for urging the upper jaw member toward the opening side.

[0009]

According to the structure of the present invention, the upper jaw member is positioned by engaging the hook of the front end with the ear of the can-like container from above and operating the lifter to raise the rear end. Can be raised, and at this time, the lower jaw member coupled to the intermediate portion of the upper jaw member can be raised by the amount of rise of the upper jaw member at the coupling position. The upper jaw member is held stationary with the tip of the hook abutting the ear of the can-like container, while the lower jaw member rises to gradually approach the upper jaw member and Since it can be closed by closing, the ears of the can-shaped container can be sandwiched between them. Therefore, by continuing to lift the lifter,
The upper jaw member and the lower jaw member can be integrally lifted to grasp the ear portion of the can-shaped container and lift it. In addition, the hoisted can-shaped container can be transported to any place by a trolley.

When the hook is provided with a pressing tip corresponding to the width of the lower jaw member, the upper jaw member can hold the ear portion between the lower jaw member and the lower jaw member for a long time.
There is no risk of damaging the ears.

Further, by providing a spring for urging the upper jaw member toward the opening side, the spring can raise the upper jaw member and the lower jaw member while keeping them open. Therefore, when the lower jaw member comes into contact with the ear portion of the can-shaped container and the load of the can-shaped container is applied to the lower jaw member, the lower jaw member pulls down the upper jaw member relatively and sandwiches the ear portion therebetween. After that, the can-shaped container can be lifted in the same manner.

Subsequently, when the lifter 21 is lifted, the upper jaw member 22 is pressed by the pressing tip 22 engaged with the ear D3.
Rotate so that the rear end part is lifted up around a (Fig. 3
Direction of arrow K2), and accordingly, the lower jaw member 23 starts to rise along the guide member 13,
Can engage the ear D3 from below.
That is, the lifter 21 can firmly grip the ear portion D3 of the can-like container D by the upper jaw member 22 and the lower jaw member 23 by driving only the rear end portion of the upper jaw member 22 upward. Yes (solid line in Figure 3).

By gripping the ear portion D3, the relative positional relationship between the upper jaw member 22 and the lower jaw member 23 becomes invariable, so that the can-shaped container D can be raised by raising the lifter 21 thereafter. It can be lifted up (two-dot chain line in the figure). At this time, the can-shaped container D is
Although the lower portion tends to incline rearward, such a behavior is blocked by the guide rollers 11r and 11r. Therefore, the can-shaped container D maintains the upright posture while the body portion D1 is in contact with the guide rollers 11r and 11r. To rise. That is, the can-like container D includes the upper jaw member 22, the lower jaw member 23,
It is supported at three points by the guide rollers 11r and 11r, and therefore can be safely transported via the carriage 10. After carrying the can-shaped container D, the lifter 21 can be lowered by operating a release valve (not shown), and can be safely placed on the ground.

The upper jaw member 22 has the hook 2
By bending 2h toward the lower jaw member 23 at an acute angle, it is possible to enter the inside of the ear D3 while straddling the ear D3 largely. Therefore, in the upper jaw member 22, a fastening metal fitting D4 for resealing is attached to the ear portion D3, and the lid plate D2 is attached.
Even the can-shaped container D resealed by the above can be transported as it is (FIG. 4). Further, the present invention can be similarly applied to a resin can having a large ear portion D3.

Other Embodiments The upper jaw member 22 has the upper jaw member 2
A spring 27 for urging 2 toward the opening can be attached (FIG. 5). The spring 27 is a tension spring, and one end thereof is hooked in a hooking hole P3 provided in the upper jaw member 22 at an intermediate position between the pins P1 and P2. The other end of the spring 27 is hooked in a hooking hole P4 provided at the tip of an extension member 27b that hangs along the guide member 13 from the rear end of the lower jaw member 23.

The spring 27 pulls down the rear portion of the upper jaw member 22 with respect to the pin P2, so that the upper jaw member 2
2 can be maintained in an opening posture that is inclined forward and upward.
Therefore, when the upper jaw member 22 is lifted by the lifter 21, the lower jaw member 23 is pulled up via the spring 27, so that the upper jaw member 22 and the lower jaw member 23 bring the upper jaw member 22 into the open posture. It can be easily positioned at the height of the ear D3 of the can-like container D while keeping it.

By moving the carriage 10 forward, the lower jaw member 23
When the lower jaw member 23 rises and comes into contact with the ear portion D3 by pressing the upper jaw member 2 against the body portion D1 and operating the lifter 21, the spring 27 is then stretched and the upper jaw member 2
The second hook 22h can be engaged with the ear D3 from above. The upper jaw member 22 is the lower jaw member 2
This is because, when 3 abuts on the ear D3 and its rise is blocked, thereafter, as the lifter 21 rises, the hook 22h swings downward about the pin P2. Therefore, if the lifter 21 is further raised, thereafter, the upper jaw member 22 and the lower jaw member 23 are exactly the same as in the previous embodiment.
Can hold the ear D3 and lift the can-shaped container D upward.

In the above description, the lifter 21 is exemplified by a manual hydraulic jack, but this can use any manual or electric drive mechanism such as a feed screw type or a gear type. That is, these drive mechanisms may be operated, for example, by loading a battery on the truck 10 and operating the motor. The caster R of the trolley 10
1, R1, R2 and the guide rollers 11r, 11r can be arbitrarily added. Further, the pressing tip 22a is
This may be omitted.

[0030]

As described above, according to the present invention, the lifter, the upper jaw member connecting the rear end portion to the lifter, and the lower jaw member connecting to the intermediate portion of the upper jaw member are provided. As a result, the upper jaw member can drive the lower jaw member upward by pulling up the rear end portion via the lifter, and at this time, the lower jaw member and the upper jaw member are sequentially placed in a can-shaped container. Since it is possible to firmly grip the ears while engaging with the ears of
There is an excellent effect that a stable gripping operation can be realized without requiring a node link and having an extremely simple structure.
