Description

[Detailed description of the invention] [Field of industrial application] The present invention provides an alignment device that aligns itself at the time of receiving the goods so as to avoid accumulating transfer errors when transferring objects having shafts at both ends. This relates to the equipped loading truck.

[Conventional technology]

FIG. 7 shows a roll paper 1 being conveyed within a paper mill, and a spool 2, which serves as a protruding shaft portion, is attached to both ends for convenience of attachment to a paper winding machine, conveyance, and storage.

As shown in Figure 8, this roll paper 1 is transported between paper mills A ₁ and A ₂ and processing factory B, and a roll stocker is placed between the two factories to adjust the balance of production between the two processes. S is placed for temporary intermediate storage.

Conventionally, the roll paper 1 was transported on the road using a trailer, but as shown in Figures 4 and 5, a receiving cart C is run unmanned on the rail R connecting each factory As a result, an improvement has been made to save labor and increase the efficiency of transportation by arranging a loading/unloading device 3 at each cargo delivery location.

The loading/unloading device 3 is a ceiling crane type automatic transfer device that transfers the roll paper 1 to and from the cart C, and as shown in FIG. A ceiling crane 5 runs and stops on a rail 4 laid on the ceiling crane 5, and the spool 2 of the roll paper 1 is suspended from a hook hanging from the ceiling crane 5, and the roll paper 1 with the spool 2 is moved between the ceiling crane 5 and the trolley C.
Give and receive.

In the loading/unloading device, in order to take out the empty spool from the cart C and load the roll paper 1 onto the cart C at the same time, in addition to the transfer table 6 for the roll paper 1, there is also an empty spool installed next to the cart C. Temporary storage stand 7 for temporarily storing
will be provided.

Further, in the roll stocker S, as shown in FIG. 3, a rail is provided on the ceiling of a crane aisle formed between shelves arranged in parallel, and the crane 8 runs on this rail.

In addition, the traverser 9 runs on a rail provided almost at right angles to the crane aisle, and the crane 8
The operator transfers to the traverser 9 to move between multiple rows of shelves and transfers the roll paper 1 with spools 2 stored on the shelves to the cart C.

Carriage C moves between the roll paper delivery facilities as described above.
The roll paper 1 with the spool 2 is transferred after the carriage C moves and is positioned and stopped, but there is an error in the position of the trolley C that is automatically positioned and stopped, and
The operation of transferring the roll paper 1 also involves errors in the transfer position.

Therefore, when the same roll paper is transferred repeatedly, errors in the stop position of the trolley and errors in the position during transfer cause the position of the roll paper to cumulatively deviate from the reference position, which hinders the automatic transfer operation. There is a problem to come.

In order to solve this problem, an alignment device is required that always corrects the placement position of the roll paper 1 on the cart C that is the object of cargo delivery.

However, self-aligning devices that automatically correct the position of the placed article are generally complex and have the disadvantage of requiring a large trolley structure. No alignment device has been found that is suitable for the shape of the transported object.

The present invention solves these problems and provides a truck equipped with an alignment device that has a simple structure and has an excellent alignment function.

[Means for solving problems]

In the present invention, a transported object having a shaft protruding from both end faces and having an annular recess in the protruding part is transferred from a crane or the like that suspends the shaft to the upper surface of a cargo carrier,
In the cargo carrier that supports the annular recess of the transported object and transports it to a predetermined transfer position, a movable platform is fixed to two locations in the longitudinal direction of the cargo carrier via an elastically deformable rubber material, and both movable A concave member having a concave upper surface and loosely fitting into the annular recess is provided on the upper surface of the table, and a guide plate is provided upright on both sides of the concave member, and the interval between the guide plates is such that the distance between the guide plates is set so that the annular recess is inserted into the concave member. It is characterized by being formed in a size that provides guidance.

[Effect]

As the conveyed object descends onto the two alignment devices configured as described above, the annular recess on the surface of the guide plate is roughly moved in position by the guide plate in the direction perpendicular to the axis of the shaft. When the side wall of the annular recess hits the side surface of the guide plate, the position is corrected in the axial direction of the shaft.

When the conveyed object further descends, the shaft is placed on the concave member, and the lower surface of the shaft is held by the concave member from front to back and left and right, so the position of the shaft is precisely corrected in the axial direction and in the direction perpendicular to the axis. Ru.

In this way, each time the transported object is placed on the trolley, it is aligned in the axial direction and in the direction perpendicular to the axis, so even if the transported object is repeatedly transferred, its position is corrected based on the trolley reference, so there is no position error. It is not cumulative.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings. Fig. 1 is a front view of the alignment device provided on the cargo receiving cart C, Fig. 2 is a plan view of the alignment device, Fig. 9 is a perspective view of the alignment device, and Fig. 10 is a view of the shaft of the transported object. It is a side view explaining the relationship with an alignment device.

Rubber materials 10 are fixed to the upper surface of the cargo receiving cart C at two locations in the longitudinal direction (front and rear direction) of the receiving cart C,
A movable base 13 is fixed on each of the rubber members 10.

The rubber material 10 is elastically deformable and has sufficient load bearing capacity for the weight of the roll paper 1.

A concave member 11 having a concave upper surface is fixed approximately at the center of the movable base 13.

The width E' of the concave member 11 is smaller than the width E of the annular recess 2a provided in the spool 2, which is the shaft of the roll paper 1, and an inclined surface 11a is provided at the end of the concave member 11. Therefore, when the roll paper 1 suspended from the ceiling crane 5 descends, the annular recess 2a loosely fits into the concave member 11 while being guided by the inclined surface 11a (see FIG. 10).

At this time, if the annular recess 2a is out of position, the annular recess 2a hits the inclined surface 11a,
Since the inclined surface 11a is pushed laterally, the rubber material 10
is elastically deformed and the annular recess 2a is loosely fitted into the concave member 11, and then the rubber material 10 is elastically returned, so that the transfer position of the roll paper 1 in the axial direction is determined.

Guide plates 12 are provided on both sides of the concave member 11 .

The concave member 11 is a concave member on which the shaft portion 2 is placed, and its radius of curvature r is equal to or slightly larger than the radius of the annular recess 2a.

Therefore, the annular recess 2a can easily fit into the concave member 11.
The shaft portion 2 comes into contact with the top and restricts movement of the shaft portion 2 in the direction perpendicular to the axis.

Further, the width dimension E' of the concave surface member 11 comes into contact with the groove width direction of the annular recess 2a and restricts the movement of the shaft portion 2 in the axial direction.

The guide plates 12 are erected on the movable table 13 facing both sides of the concave member 11, and the distance D between the two guide plates 12 is slightly larger than the diameter of the annular recess 2a. Perform rough positioning of the shaft portion 2.

Further, the width E of the guide plate 12 is made smaller than the axial dimension of the annular recess 2a, and the upper half 12a of the guide plate 12 has a tapered shape that becomes smaller toward the top, so that the descending shaft portion 2 annular recess 2a of
The axial position error of the shaft portion 2 is corrected by loosely fitting it into the shaft portion 2.

The cargo receiving cart C equipped with the alignment device configured as described above receives the roll paper 1 with the spool 2 suspended and lowered from the crane 5 or 8 while aligning as follows.

When the roll paper 1 descends, the annular recess 2a is inserted between the upper halves 12a, 12a.

When the roll paper 1 further descends, the upper half 12a guides the annular recess 2a, but if the roll paper 1 is misaligned with respect to the cart C, the annular recess 2a guides the tapered part of the upper half 12a. The movable base 13 tilts due to the elastic deformation of the rubber material 10, and the annular recess 2a descends along the guide plate 12.

Thus, the shaft portion 2 placed on the concave member 11
The annular recess 2a has the same width as the curved surface r of the concave member 11.
The movable platform 13 is held by E' for precise positioning, and the movable platform 13 is returned to its original shape by the elastic force of the rubber material 10, so that it is correctly positioned on the cargo carrier C.

The receiving cart carrying the roll paper moves to the next receiving position, but since the rubber material 10 of the alignment device absorbs the shock during transportation, this alignment device also serves as a shock absorbing function for the receiving cart C. Therefore, the structure of the entire loading truck can be simplified.

〔effect〕

The present invention has the following effects.

(1) The structure of the alignment device is extremely simple and compact.

Therefore, it is highly durable and the volume of the entire loading truck can be reduced.

(2) As long as the shape of the object to be conveyed has shaft portions at both ends, the cart with an alignment device of the present invention can be used without being limited to roll paper.

Furthermore, since it does not have a complicated floating mechanism, it can smoothly perform the alignment function even if the object to be transported is heavy.

(3) Since the rubber material used as the alignment device functions as a cushioning material while the bogie is running, there is no need to provide a special suspension structure to the bogie, and the overall structure of the bogie can be simplified.
