Description

The present invention relates to a transfer device for transferring a plate material having an uneven cross-sectional shape sent from the transfer device and a method for transferring the plate material.

In a building, for example, a so-called corrugated steel plate having an uneven cross-sectional shape is used in order to form a base of a floor structure or a ceiling structure so as to be bridged between the beams (see, for example, Patent Document 1). ).
The corrugated steel plate (plate material) is manufactured by giving a strip-shaped steel plate a cross-sectional shape of unevenness extending in the longitudinal direction by a forming machine on a production line and then cutting the steel plate to a predetermined length. The corrugated steel plate cut to a predetermined length is conveyed on the conveying device.

The corrugated steel sheets are moved from the transport device to the loading platform in the lateral direction with respect to the transport direction, and after stacking a plurality of the corrugated steel plates, they are transported to another storage location by a forklift or the like. The corrugated steel sheet was manually moved from the transport device to the loading platform by a worker lifting each end of the corrugated steel sheet in the longitudinal direction.
Since the corrugated steel sheet has irregularities along the longitudinal direction, when the corrugated sheet steel is moved in parallel, the irregularities on the loading platform side of the corrugated steel sheet to be moved are moved to the loading platform first. May engage (collide) with the unevenness of. Engagement of corrugated steel plates in unevenness hinders smooth movement of corrugated steel plates and makes it difficult to stack corrugated steel plates.
By lifting the corrugated steel plates and stacking the corrugated steel plates from directly above so that the workers do not engage the corrugated steel plates with each other, it is possible to avoid the engagement between the corrugated steel plates during the movement. However, the length of the corrugated steel sheet is, for example, 6 to 7 m, and the weight is also large by that amount, and the continuous lifting and moving of the corrugated steel sheet to a predetermined height causes an increase in work load. It was supposed to be. Therefore, it has been desired to reduce the work load associated with the movement of the corrugated steel sheet.

It is preferable to have a driving unit for lifting.

Further, it is preferable to provide a pair of guide members which are installed in the storage place at predetermined intervals along the transport direction and guide the loading of the plate material into the storage place.

Further, it is preferable that the distance between the pair of guide members is narrowed toward the delivery direction of the plate material from the transport device to the storage place.

Further, it is preferable to provide a stopper that is installed in the storage place at a predetermined distance from each other along the transport direction and stops the plate material that has been sent out by the delivery mechanism.

<Transfer device>
The transfer device 100 moves the corrugated steel plate (plate material) P having the uneven cross-sectional shape sent over the transfer device 1 to the storage place of the corrugated steel plate P. The corrugated steel plate P is provided on the side of the transport device 1 with respect to the transport direction T.
The corrugated steel plate P is, for example, a steel plate in which irregularities are imparted to a strip-shaped steel plate by a molding machine (not shown), and is also called a keystone plate. The unevenness is formed along the longitudinal direction of the corrugated steel plate P. The corrugated steel sheet P is fed so that its longitudinal direction is along the transport direction T of the transport device 1.

As shown in FIG. 1, the transfer device 100 includes a delivery mechanism 3 that sends out a corrugated steel plate P from a transport device 1 on which a corrugated steel plate P is placed, a delivery mechanism 5 that relays the transfer of the corrugated steel plate P, and a corrugated steel plate P. It is provided with a loading platform 7 to be loaded with.

For convenience of explanation, first, the transport device 1 will be described.
The transport device 1 has a plurality of cylindrical members 11 arranged in a direction orthogonal to the transport direction T of the corrugated steel plate P. The cylindrical members 11 are provided at predetermined intervals along the longitudinal direction of the transport device 1. Each cylindrical member 11 is rotatably attached to the frame body of the transport device 1. The transport device 1 includes a stopper (not shown) that stops the corrugated steel plate P that has slid on the cylindrical member 11 along the transport direction T at a predetermined position.
In the transport device 1, the corrugated steel plate P is placed on a plurality of cylindrical members 11. That is, the mounting surface on which the corrugated steel plate P is placed is a virtual surface formed on a plurality of cylindrical members 11 on which the corrugated steel plate P is placed.

(Sending mechanism)
The delivery mechanism 3 sends the corrugated steel plate P from the transfer device 1 toward the loading platform 7. As shown in FIG. 1, two delivery mechanisms 3 are provided in the transport device 1 at predetermined intervals along the transport direction T of the corrugated steel plate P. Specifically, the two delivery mechanisms 3 and 3 are respectively arranged between the two cylindrical members 11 of the transfer device 1.
As shown in FIG. 2, the delivery mechanism 3 has a delivery unit 31 that sends out the corrugated steel plate P on the cylindrical member 11 of the transfer device 1 to the delivery mechanism 5, and a drive that diagonally lifts the delivery unit 31 toward the delivery mechanism 5. It has a part 32 and.

As shown back to FIG. 1, the two delivery units 31 are arranged in the transport device 1 at an angle to the transport direction T of the corrugated steel plate P and in parallel with each other. Specifically, the delivery unit 31 is arranged so that its axis x diagonally intersects the transport direction T of the corrugated steel sheet P and extends in the direction opposite to the transport direction T.
As shown in FIG. 2A, the delivery unit 31 is provided in the transport device 1 below the mounting surface of the cylindrical member 11. That is, the delivery unit 31 is in a state that does not hinder the sliding of the corrugated steel plate P on the transport device 1 in the non-drive state (initial state) in which the delivery unit 31 is not lifted by the drive unit 32.
For the delivery unit 31, for example, a known roller conveyor in which a cylindrical roller 31b is rotatably held in the frame body 31a can be used. The delivery unit 31 has a dimension longer than that of the cylindrical member 11 of the transfer device 1, and the end portion on the delivery mechanism 5 side slightly protrudes from the transfer device 1.
The delivery unit 31 has a rotation support portion 31c at the end on the delivery mechanism 5 side so that the end on the side opposite to the delivery mechanism 5 is lifted upward by the elevating motion by the drive unit 32.

The drive unit 32 is provided below the transmission unit 31 and is connected to a predetermined position of the frame body 31a of the transmission unit 31. The drive unit 32 can move the delivery unit 31 between a position below the mounting surface of the corrugated steel plate P in the transport device 1 and a position above the mounting surface.
A known elevating device can be used for the drive unit 32. In the illustrated embodiment, for example, the drive unit 32 has a cylinder portion 32a and a rod portion 32b housed in the cylinder portion 32a and expandable and contractible. One end of the rod portion 32b is connected to the frame body 31a of the delivery portion 31. The drive unit 32 is, for example, pneumatically configured, and the expansion and contraction of the rod unit 32b is adjusted steplessly by sending compressed air to the cylinder unit 32a.
The drive unit 32 lifts the delivery unit 31 diagonally toward the delivery mechanism 5 so that at least the entire corrugated steel plate P is located above the mounting surface in the transfer device 1.

(Delivery mechanism)
As shown in FIGS. 1 and 3, the delivery mechanism 5 relays the delivery of the corrugated steel plate P delivered from the transport device 1 by the tilted delivery unit 31 to the loading platform 7. The delivery mechanism 5 is a known roller conveyor having a plurality of rollers 52 rotatably attached to the frame body 51. Four delivery mechanisms 5 are provided at substantially equal intervals along the transport direction T of the corrugated steel sheet P. One end of the delivery mechanism 5 is fixed to the transport device 1, and the other end extends diagonally downward to the loading platform 7.
Each delivery mechanism 5 extends in the same direction as the delivery unit 31 of the delivery mechanism 3. The delivery mechanism 5 is provided so as to sandwich one delivery mechanism 3 by two delivery mechanisms 5 on the upstream side in the transport direction T and one delivery mechanism 3 by two delivery mechanisms 5 on the downstream side.

(Loading platform)
The loading platform 7 is formed by combining a plurality of steel frame members, and is installed in a storage place for the corrugated steel plate P. As shown in FIGS. 1 and 3, the corrugated steel plate P sent out from the transport device 1 by the delivery mechanism 3 and transferred via the delivery mechanism 5 is loaded on the loading platform 7. In the loading table 7, the corrugated steel plates P transferred from the transfer device 1 are stacked so that their axis y is substantially parallel to the transfer direction T and to a predetermined height (number of sheets).
The loading platform 7 is installed so that its longitudinal direction is parallel to the extending direction (or transport direction T) of the transport device 1. The loading platform 7 has a pair of guide plates (guide members) 71 and a stopper 72 for stopping the transferred corrugated steel plate P.
The pair of guide plates 71 guide the loading of the corrugated steel plate P sent out from the transport device 1 onto the loading table 7. The pair of guide plates 71 are provided at predetermined intervals from each other in the longitudinal direction of the loading platform 7. The pair of guide plates 71 are arranged so as to face each other with their planes facing each other, and are arranged so as to narrow the distance between the corrugated steel plates P toward the delivery direction S. That is, the pair of guide plates 71 are arranged so that the widest space is formed on the inlet side where the corrugated steel plate P is loaded on the loading platform 7, and the narrowest space is formed on the side opposite to the inlet side. The dimension of the narrowest interval in the pair of guide plates 71 substantially matches the length dimension of the corrugated steel plate P.
The stopper 72 receives the corrugated steel plate P sent out from the transport device 1 on the loading platform 7. Two stoppers 72 are provided at the edge of the loading platform 7 on the opposite side of the transport device 1 along the longitudinal direction of the loading platform 7 (parallel to the transport direction T) at predetermined intervals. ..

<Transfer method of corrugated steel sheet>
Next, a method of transferring the corrugated steel plate P by the transfer device 100 from the transfer device 1 to the loading platform 7 will be described with reference to FIGS. 1 to 4. 4A and 4B are schematic plan views showing a transfer process of a corrugated steel sheet, FIG. 4A is a diagram showing delivery of a corrugated steel sheet from a transfer device by a delivery mechanism, and FIG. 4B is a diagram showing transmission of the corrugated steel sheet. It is a figure which shows the sliding of a corrugated steel sheet in a delivery mechanism, FIG. 4C is a figure which shows delivery of a corrugated steel sheet from a delivery mechanism to a loading platform, and FIG. It is a figure which shows the loaded state.
The corrugated steel sheet P, which is provided with irregularities in the molding machine and is cut to a predetermined length by the cutting machine, is fed on the transport device 1 in the transport direction T. As shown in FIG. 1, the sent corrugated steel plate P slides on the cylindrical member 11 of the transport device 1 and is stopped at a predetermined position.

As shown in FIG. 2A, since the delivery mechanism 3 is located below the mounting surface of the corrugated steel plate P on the cylindrical member 11 of the transport device 1, the transport of the corrugated steel plate P is not hindered.
As shown in FIG. 2B, the drive unit 32 of each transmission mechanism 3 simultaneously tilts and lifts the transmission unit 31 in the transmission direction S. When the delivery portion 31 is lifted above the cylindrical member 11, the corrugated steel plate P slides diagonally downward on the roller 31b of the delivery portion 31 toward the delivery direction S.

As shown in FIG. 4A, since the delivery portion 31 is arranged to be tilted with respect to the transport direction T, the delivery portion 31 is similarly tilted with respect to the transport direction T at the contact point between the corrugated steel plate P and the roller 31b. The force is working. Therefore, the corrugated steel plate P placed on the transport device 1 is fed at an angle with respect to the transport direction T due to contact (friction) with the roller 31b of the delivery unit 31.
Thus, the corrugated steel plate P can be sent out to the loading platform 7 while being tilted with respect to the transport direction T so that the axis y thereof is orthogonal to the axis x of the delivery unit 31. In FIG. 4, the left end portion of the corrugated steel sheet P (the end portion on the downstream side in the transport direction T) precedes the right end portion (the end portion on the upstream side) in the delivery direction S.

As shown in FIG. 4B, since the delivery mechanism 5 on the downstream side of the delivery unit 31 in the transmission direction S is provided along the extending direction of the transmission unit 31, the corrugated steel plate P is shown in FIG. While maintaining the state shown in (a), it slides on the roller 52 of the delivery mechanism 5.

As shown in FIG. 4 (c), the delivery mechanism 5 delivers the corrugated steel plate P to the loading platform 7 with the left end portion in front. The corrugated steel plate P diagonally enters between the pair of guide plates 71.
First, the corrugated steel plate P is guided while the left end portion is in contact with the guide plate 71 on the left side in the drawing, and abuts on the stopper 72 on the left side in the drawing. At this time, the right end portion of the corrugated steel plate P slides on the corrugated steel plate P that has already been loaded, when it is delivered from the delivery mechanism 5 to the loading platform 7 or after it has been delivered. Finally, as shown in FIG. 4D, the corrugated steel plate P is rotated around the stopper 72 on the left side as a fulcrum until the right end portion abuts on the stopper 72 on the right side, and is loaded onto the loading platform 7. Thus, the corrugated steel plates P and P are stacked in a state in which the ends are aligned in the lateral direction and the longitudinal direction (a state in which the axes y coincide with each other).
As described above, the transfer of the corrugated steel plate P from the transfer device 1 to the loading platform 7 is completed.

Since the transfer device 100 sends the corrugated steel plate P from the transfer device 1 to the loading platform 7 in a state where the axis y thereof is oblique to the axis y of the corrugated steel sheet P already loaded, the corrugated steel sheet P is already loaded on the loading platform 7. It is possible to slide on the corrugated steel plate P. That is, the corrugated steel plate P to be newly loaded can be transferred to the loading table 7 without the unevenness engaging with the unevenness of the corrugated steel plate P already loaded.
Here, "engagement between unevenness" means, for example, that the corrugated steel plate P to be newly loaded fits into the convex portion of the corrugated steel plate P already loaded at the concave portion during the transfer. It means to put it away.

Further, conventionally, a worker approaches the transport device 1 and lifts the corrugated steel plate P to carry it from the transport device 1 to the loading platform. However, the transport device 100 brings the corrugated steel sheet from the transport device 1 to the loading platform 7. The transfer of P can be easily and quickly performed without the intervention of a worker.

<Others>
The present invention is not limited to the above-described embodiment, and can be appropriately modified without exceeding the scope of the present invention. For example, the number of delivery mechanisms 3 installed is not limited to two and may be three or more, and the number of delivery mechanisms 5 installed is not limited to four and may be three or five or more. ..
Further, although the delivery mechanism 3 is arranged at an angle to the upstream side with respect to the transport direction T, it may be arranged at an angle to the downstream side. In this case, the delivery mechanism 5 is also arranged at an angle downstream of the transport direction T, similarly to the delivery mechanism 3.
