The main part consists of 0 and .

However, such a stabilizer device 50,
At the moment when the workpiece A on the fork 53 is held down by the presser body 60, there is a gap between the base body 51 and the roller 55, and the movable body 54 and the arm 57 are deformed, so that the presser body 60 moves as shown in FIG. Move backward as shown by the chain line.

On the other hand, at the moment when the pressure exerted by the presser foot 60 is released, the presser foot 60 moves forward from the chain line in FIG. 6 as shown by the solid line.

For this reason, there was a problem in that the upper surface of the object A was damaged due to the back and forth movement of the presser body 60.

In particular, when the object A to be handled is a stack of many tin plates, papers, etc., the upper one may shift as shown in Figure 6, causing damage due to sliding between the pieces, and making it difficult to handle. There was also a risk that the entirety of Item A would collapse.

(Problems that the invention attempts to solve) This invention was created in view of the problems mentioned above and to solve them, and its purpose is to:
To provide a stabilizer device capable of holding down an object without damaging it.

(Means for Solving the Problems) The stabilizer device of the present invention includes a base body, a fork provided on the base body on which an object can be placed, and at least a tip of the fork above the fork that is in contact with the base body. Consists of an arm that can be raised and lowered, a support body that is swingably provided at the tip of the arm, and a plurality of presser rollers that are rotatably provided on the support body and that are rotatable about a horizontal shaft and that can press down the object from above. There are characteristics in what you do.

(Function) After the object is placed on the fork, when at least the tip of the arm is lowered relative to the base, the support and the presser body are also lowered, so that the object is held down by the presser section of the presser body.

Conversely, when at least the tip of the arm is raised, the support body and the presser body also rise, so that the presser part of the presser body separates from the object to be handled.

The support body moves back and forth at the moment when the object to be handled is pressed and at the moment when the object is released from being held down.

However, since the presser part of the presser body can move back and forth with respect to the support body, the movement of the support body in the back and forth direction is not transmitted to the workpiece.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a longitudinal sectional side view showing a stabilizer device according to an embodiment of the present invention. FIG. 2 is a vertical sectional side view showing an enlarged view of the main parts. FIG. 3 is a longitudinal sectional front view of FIG. 2.

The stabilizer device 1 includes a base body 2, a fork 3,
Its main parts are composed of an arm 4, a support body 5, and a presser body 6.

The base body 2 has an upright shape.

In this example, the channel member 7 is made up of a pair of left and right channel members 7 having substantially U-shaped cross sections and facing grooves, and a lower connecting member 8 that connects them.

Although not shown, the base body 2 is attached to an elevating body of an elevating device equipped with a cargo handling vehicle such as a forklift.

The fork 3 is provided on the base body 2 on which the object A can be placed.

In this example, a pair of left and right fingers are suspended from a finger bar 9 attached to the lower front surface of the base body 2.

The arm 4 is above the fork 3 and at least its tip can move up and down with respect to the base body 2.

In this example, a pair of left and right arm plates 1 having a substantially L shape are shown.
0 and a rear connecting plate 11 that connects them, and is attached to the front part of the movable body 12.

The movable body 12 includes a pair of left and right movable plates 13 having an inverted L shape, and an upper connecting plate 14 that connects these movable plates 13.
The front connecting plate 15 also includes a front connecting plate 15 and a roller 16 that is disposed above and below each movable plate 13 and rolls along the groove of the channel material 7 of the base body 2.
A rear connecting plate 11 of the arm 4 is attached to the rear connecting plate 11 of the arm 4.

A stabilizer cylinder 17 is interposed between the lower connecting member 8 of the base body 2 and the upper connecting plate 14 of the movable body 12, and by expanding and contracting the stabilizer cylinder 17, the movable body 12 and the movable body 12 are fixed to the base body 2. The arm 4 is raised and lowered.

The support body 5 is swingably provided at the tip of the arm 4.

In this example, a pair of left and right vertical plates 18, a horizontal plate 19 connecting the lower parts of these plates, a hanging plate 20 provided downward from both left and right ends of these plates, and a tip of the arm plate 10 of the arm 4 and the vertical plate 18 It consists of a swing shaft 21 in the left-right direction that pivots between the center of the shaft and the center of the shaft.

The presser body 6 includes a presser part 22 that is provided on the support body 5 and can press down the object A from above, and the support body 5
The presser part 22 can move back and forth relative to the holding part 22.

In this example, a plurality of hollow pressing rollers 23 are arranged between the hanging plates 20 of the support body 5 at predetermined intervals in the front-rear direction, and shafts are attached to the hanging plates 20 to move them back and forth (rotate back and forth). The outer periphery of each presser roller 23 serves as a presser portion 22.

The object A is placed on the fork 3 and transported.

In this example, a large number of tin plates are stacked one on top of the other.

Next, the operation will be explained based on such a configuration.

The object A is placed on the fork 3.

Then, when the stabilizer cylinder 17 is shortened, the movable body 12, the arm 4, the support body 5, and the presser body 6 each descend with respect to the base body 2, so that the presser body 6
The presser portion 22, that is, the outer periphery of each presser roller 23 comes into contact with the upper surface of the object A to press it.

Conversely, when the stabilizer cylinder 17 is extended, the movable body 12, arm 4, support body 5, and presser body 6 each rise relative to the base body 2, so that the presser part 22 of the presser body 6 is lifted from the top surface of the object A. Leave.

At the moment when the object A is held down, the support 5 moves backward due to the gap between the channel material 7 of the base 2 and the roller 16 of the movable body 12, and the deformation of the movable body 12 and the arm 4. At the moment when the object A is released from being held down, the support body 5 moves forward by returning from the holding state.

When the support body 5 moves backward or forward, the presser roller 23 of the presser body 6 rolls on the upper surface of the object A and rotates around the horizontal axis 24 while pressing it, so that it is not handled as the presser roller 23. The top surface of object A never slides.

Although the base body 2 is composed of the channel material 7 and the lower connecting material 8 in the previous embodiment, the base body 2 is not limited to this.
It can be structured as appropriate.

In the previous embodiment, the forks 4 were provided on the base body 2 via the finger bars 9, but the fork 4 is not limited to this, and may be provided directly on the base body 2, for example.

In the previous embodiment, the arm 4 is attached to the movable body 12 that can be raised and lowered relative to the base body 2, but the present invention is not limited to this. The stabilizer cylinder 17 is interposed between the base body 2 and the arm 4, and the end of the arm 4 is raised and lowered by rotating the arm 4 with respect to the base body 2. It's okay.

In the previous embodiment, the support body 5 is configured to be able to swing only around the swing axis 21 in the left-right direction with respect to the arm 4, but the support body 5 is not limited to this; It may also be possible to swing both around the axis in the front and rear directions.

(Effects of the invention) As described above, according to the present invention, the following excellent effects can be achieved.

(1) Since a presser body is provided in which the presser part can move back and forth with respect to the support body, even if the support body moves back and forth, it is possible to press the object without damaging it.

(2) Since only the support body and presser body need to be changed, it can be applied to existing stabilizer devices very easily.

(3) Since the support is equipped with multiple presser rollers that can freely rotate on the horizontal axis, when the support moves in the front-back direction, the movement between the object to be handled and the presser roller closest to it is It is possible to absorb the so-called movement directly.

(4) Since the support is equipped with a plurality of presser rollers that can freely rotate around the horizontal axis, when the support moves in the front-back direction, the presser rollers that hold down the object will roll freely and the movement will be prevented. It is possible to absorb the so-called movement quickly.

(5) Since the support body only needs to be provided with a plurality of press rollers, the structure is relatively simple, there are few occurrences of breakdowns, and maintenance is easy.
