Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to suspending a roll-shaped object from below a self-propelled train in the direction of its axis or parallel to the traveling direction of the self-propelled train. This invention relates to a roll-shaped article loading and conveying device that loads and conveys roll-shaped articles.

(Prior art and its problems) As a conveyance device that conveys a roll-shaped object in a suspended state, a device that suspends the roll-shaped article horizontally in the direction of its axis or perpendicular to the conveyance direction is generally used. . However, when a suspended roll-shaped object is stopped at a fixed position on the conveyance path and a covering material is wrapped around the roll-shaped object while it is suspended, the roll-shaped object is
Wrapping of the covering material is convenient for carrying out work, etc., by suspending and transporting the product in the axial direction or in a direction parallel to the transport direction.

Therefore, an elevating frame is suspended from the self-propelled transport train, and the rear end of the roll support rod parallel to the traveling direction of the self-propelled train is supported in a cantilevered manner. The roll-like object is kept waiting concentrically with the roll-like object support rod that has been lowered to the lowering limit by the lifting frame, and the roll-like object support rod at the lower limit is moved by the forward running of the self-propelled train. A roll-shaped material loading and conveying device was considered in which the roll-shaped material is inserted into a core hole, and then the lifting frame is raised to lift the roll-shaped material by the roll-shaped material support rod.

In such a roll-shaped object loading and conveying device, if the roll-shaped object supporting rod can be passed through the core hole of the roll-shaped object waiting at the roll-shaped object loading place and lifted up, the self-propelled train can be stopped. Even if the position varies a little, it will not have much of an effect.There are several rolls waiting in the loading area in the axial direction, and these rolls are lifted one by one starting from the first one. If the length of each roll is not constant, the tip of the roll support rod should be automatically stopped before the rear end of the core hole of the first roll. It was necessary to accurately stop the running train at a position corresponding to the length of the roll-shaped material to be loaded, which made it extremely difficult to control the running and stopping of the self-running train itself, making it difficult to put it into practical use.

(Means for Solving the Problems) In order to solve the conventional problems as described above, the present invention has the following features:
An elevating frame is suspended from a self-propelled train running on a fixed travel route via an elevating drive means, and the rear end of a roll-shaped material support rod parallel to the traveling direction of the self-propelled train is cantilevered onto the elevating frame. A movable trolley capable of reciprocating within a certain range parallel to the travel route of the self-propelled train is provided at the loading location for roll-shaped goods, and a movable trolley is lowered by the elevating frame at the lower half of the reciprocating route of the movable trolley. A roll-shaped object support part that supports a roll-shaped object concentrically with the roll-shaped object support rod that has been lowered to the limit, and a reciprocating drive means for the movable cart are disposed, The present invention proposes a roll-shaped article loading and conveying device that is provided with a coupling means for coupling and integrating with the above-mentioned self-propelled train.

A mounting portion 69 and a positioning hole 70 are provided as elevating frame positioning and supporting means having the same function as that of 6.

To explain how to use the roll-shaped material loading and unloading device configured as above, as shown in FIG. A roll-shaped object support section 71 for supporting a roll-shaped object is disposed concentrically with the roll-shaped object support rod 8 which has been lowered to its lower limit by the lifting frame 7 of 17. This roll-shaped object support section 71 may also serve as a roll-shaped object conveyance means, or may simply support a roll-shaped object conveyed by another conveyance means. .

A plurality of roll-like objects W, in which a long roll-like object is divided into a plurality of pieces in the fine direction, are placed on the roll-like object support section 71.
1-W3 are placed in series. In this state, as shown in the figure, the movable trolley I7, which is at the retraction limit position (the piston rods 29a and 31a of the cylinders 29 and 31 are both at the retraction limit), moves by itself to a predetermined position between the side frames 20a and 2Ob. A train 1 is made to enter and stopped, and the self-propelled train 1 is brought into a free state without applying brakes. Of course, the elevating frame 7 is at the upper limit position U.

Next, as shown in FIG.
actuates the pair of clamp arms 34 as described above.
The clamped parts 16 for coupling of the mobile electric train 1 are clamped by the train clamp parts 36 of a and 34b, and the clamped parts 38 for coupling of the movable bogie side frame 20b are clamped by the side frame clamp parts 37 of the clamp arms 34a and 34b. Clamp and hold.
At the same time as the movable bogie 17 and the self-propelled train l are connected and integrated, the upper portions of the pair of left and right side frames 20a, 20b of the movable bogie 17 are connected to each other by the coupling means 33. At this time, the self-propelled train 1 is free, so even if the stopping position is slightly deviated, the self-propelled train 1 is automatically corrected to the correct position by the clamping action of the clamp arms 34a and 34b, and then moves onto the movable bogie 17. Connected and integrated.

In this state, the elevating frame 7 of the self-propelled train 1 is lowered to the lowering limit position by the elevating drive means 6, and as shown by the imaginary line in FIG. The lifting frame 7 (
Position the roll support rod 8) at a predetermined level. Then, the cylinder 29 of the first drive means 23 in the reciprocating drive means 22 is operated to advance the piston rod 29a, and the pinion gear 30 is advanced by a prescribed stroke S1. As a result, the pinion gear 30, which engages with the fixed rack gear 27 and moves forward without rotating, moves the intermediate movable body 26 through the specified stroke S through the movable rack gear 28.
It is moved forward by a stroke S2 that is twice l. This forward movement of the intermediate movable body 26 is directly transmitted to the movable carriage 17 via the cylinder 31 of the second drive means 24, and the movable carriage 17 moves forward by a constant stroke S2 from the backward limit position. As a result, the roll-like object support rod 8 of the self-propelled train 1 that moves together with the movable trolley 17 moves forward by a fixed stroke S2 at the determined lowering limit position, and the tip of the roll-like object support rod 8 moves forward at the determined lowering limit position. , a certain reference position PO is reached with respect to the roll-shaped object support part 71.

From the reference position PO to the core hole W of each roll-shaped object W1 to W3
The distance to the rear end of a can be known as the front edge, and based on this information, each roll-shaped object W1 is
Insertion limit position Pi-P3 slightly before the rear end of the core hole Wa
Each insertion distance L1-L3 is calculated, and when loading the first roll-like object W1, the movable cart 17 is moved forward relative to the intermediate movable body 26 by the insertion distance Ll with respect to the roll-like object W1. The cell controller cylinder 31 of the second drive means 24 is operated by feedback control. Therefore, the self-propelled train I (roll-shaped support rod 8) integrated with the movable trolley 17 moves forward by the insertion distance L1, and the roll is inserted into the core hole Wa of the leading roll-shaped article W1 on the roll-shaped article support section 71. The object support rod 8 is inserted until its tip reaches a position slightly in front of the rear end of the core hole Wa.

Next, the elevating drive means 6 of the self-propelled train 1 is activated to raise the elevating frame 7 to the upper limit position U, and the roll-like object support rod 8 moves the leading roll-like object Wl to the roll-like object support section 71.
Lift it from above. The elevating frame 7 that has risen to the ascent limit position U is attached to the ascent positioning pin lO as shown in FIG.
It is fitted into the cylindrical positioning member 11 on the mobile train 1 side, and the lifting frame 7 (roll-shaped object support rod 8) is fixed to the mobile train 1. Once the lifting frame 7 has been raised to the upper limit position U, the clamp arms 34a and 34b of the coupling means 33 of the movable bogie 17 are opened by the cylinder 35, and the coupling between the movable bogie 17 and the self-propelled train 1 is released. Later, the self-propelled train 1 can be started and self-propelled, and the roll-shaped article W1 can be suspended and transported along the guide rail 2 to the destination location. After the self-propelled train l starts, the movable bogie 17
By contracting and retracting the piston rods 29a and 31a of both cylinders 29, 31 in the drive means 22 to the retracting limit, the piston rods 29a and 31a of the cylinders 29, 31 are moved backward to the original retracting limit position in preparation for the next loading operation.

In addition, when moving the movable trolley 17 backward, since the movable trolley 17 is in an unloaded state, even if only one side frame 20a is pulled in the backward direction using the driving means 22, both side frames 20
Check that there is no risk of deformation due to excessive force acting between a and 2, and if necessary, remove the connecting means 3 before moving backward.
3 may be activated to connect the upper portions of both side frames 20a and 20b to each other using clamp arms 34a and 34b.

When loading the second roll W2 or the third roll W3 on the roll support 71, the second drive means moves the movable cart 17 forward by the insertion distance L2 or L3 from the reference position PO. It is sufficient to control 24 cell controller cylinders 31.

At the roll-shaped object unloading place, as shown in FIG.
or waiting at the backward limit position of the reciprocating path. At this time, the two sets of clamp arms 53a, 53b and 54a, 54b in the coupling and positioning means 52 of the movable trolley 47 are as follows:
In the state shown by the imaginary lines in FIG. 12, the clamp arms 54a and 54b are closed to clamp the fixed positioning clamped member 59, and as a result, the movable carriage 47 is locked in the fixed position. ing.

In such a state, as shown in FIG. 15, the roll-shaped object W] enters between the both side frames 50a and 50b of the self-propelled train 1 suspended from the roll-shaped object support rod 8 or the movable bogie 47, and is held at a predetermined position. When the train has stopped at this point, the cylinder 55 of the coupling and positioning means 52 is actuated, and the train clamp portions 56 of the pair of clamp arms 53a and 53b are used to clamp the mobile train 1.
At the same time, the side frame clamp parts 57 of the clamp arms 53a and 53b clamp the joint clamped part 58 of the side frame 50b of the movable bogie 47, and thereby the movable bogie 47 and the self-propelled train are clamped. At the same time, the pair of left and right side frames 50a, 50 of the movable trolley 47 are connected and integrated.
The upper portions of b are connected and integrated with each other by a connecting and positioning means 52. Furthermore, clamp arms 54a, 54
b is opened to make the movable cart 47 free.

Next, the elevating frame 7 of the self-propelled train 1 is lowered to the lowering limit position by the elevating drive means 6, and as shown by the imaginary line in FIG.
The positioning bin 13 is placed on the placing portion 69 on the 7 side.
is fitted into the positioning hole 70 to position the lifting frame 7 (roll-shaped object support rod 8) at a predetermined level. When the self-propelled electric train l is started again, the movable trolley 47 that positions and supports the elevating frame 7 moves forward together with the self-propelled electric car l. As the self-propelled train 1 moves forward, the roll-shaped object support rod 8 is moved as shown by the imaginary line in FIG.
When the roll-shaped article Wl suspended from the roll-shaped article receiver reaches a fixed position P4 above the mounting stand 72, the self-propelled electric train 1 is stopped. And the roll-shaped object tray is a stand 72.
When the roll-shaped object Wl is raised slightly above the roll-shaped object support rod 8, the self-propelled electric train 1 is moved backward, and the roll-shaped object Wl is lifted up from the roll-shaped object support rod 8 on the pedestal 72. The roll-shaped material Wl is pulled out from the core hole Wa.

When the movable trolley 47 reaches the backward limit standby position shown by the solid line in FIG. is activated to open the pair of clamp arms 53a and 53b and close the clamp arms 54a and 54b as described above, thereby coupling the movable bogie 47 and the self-propelled train 1 and closing the movable bogie vehicle side frame 50.
a.

50b and the clamped member 5 fixed by the clamp arms 54a and 54b.
9 to lock the movable cart 47 in place.

Then, the elevating frame 7 is raised to the upper limit position U by the elevating drive means 6, and as shown in FIG. Once the elevating frame 7 is fixed to the train 1, the self-propelled train 1 separated from the movable trolley 47 can be moved forward toward the loading location.

Incidentally, the configuration and usage method of the roll unloading place are not limited to those of the above embodiment.

(Operations and Effects of the Invention) As described above, the roll-shaped object loading and conveying device of the present invention is capable of self-propelling in the lowered position with the roll-shaped object supporting rod of the lifting frame suspended from the self-propelled train via the lifting drive means. After moving the train forward in the running direction and inserting the roll support rod into the core hole of the roll support provided at the roll loading location, the lifting frame is raised. Then, the roll-shaped object is loaded into the roll-shaped object support rod, or the self-propelled train is moved forward to insert the roll-shaped object support rod into the core hole of the roll-shaped object. (The self-propelled train is coupled and integrated with a movable bogie driven by another drive means via a coupling means, and the movable bogie is moved forward by a reciprocating drive means,
The roll-shaped article support rod is inserted into the core hole of the roll-shaped article.

That is, the movable trolley, which is reciprocated within a certain range by a reciprocating drive means, can be easily controlled for highly accurate positioning by feedback from the ground side compared to a friction-driven self-propelled train using wheels. By integrating a self-propelled train into a bogie and moving the roll-shaped object support rod of the self-propelled train forward by controlling the movement of the movable bogie,
It is possible to easily improve the accuracy of the insertion stop position of the roll-shaped article support rod with respect to the roll-shaped article core hole.

Therefore, as shown in the example, a plurality of rolls waiting at the roll loading area are lined up in the axial direction, and these rolls must be lifted one by one starting from the first one. Even if the length of each roll is not constant, it is possible to precisely control the insertion distance of the roll support rod to ensure that only the first roll is inserted into the roll support rod. There may be situations where the second roll is caught and the roll cannot be scooped up, or the insertion depth of the roll support rod to the first roll is too shallow, making it unstable to lift the roll. This will prevent any untoward situation from occurring.

In particular, as in the embodiment, when the elevating frame of the self-propelled train, which is connected and integrated with the movable bogie by the coupling means, is lowered to the lowering limit position, the elevating frame is positioned to a certain level. When a lifting frame positioning support means is provided, the unstable roll-shaped object support rod suspended by the hanging rope is positioned at a predetermined level by the movable cart, and the rolled object is reliably and smoothly moved. It can be inserted into the core hole of an object.
