Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveying device that rolls cylindrical or barrel-shaped objects, moves them forward and backward, and transports them from a shelf.

As shown in Fig. 4, the object of the present invention is to smoothly and quickly transport a large number of cylindrical, rod-shaped, and barrel-shaped objects from deep shelves with narrow shelf spacing (narrow shelf space). It is an object of the present invention to provide a transport device capable of storing stored items and smoothly and quickly carrying out stored items from shelves.

Conventionally, in order to take stored items in and out of such shelves where the space between the shelves is narrow and there is little space between stored items or between the stored items and the shelves, it has been necessary to extend and contract means such as gripping arms and lifting forks. It has been said that it is difficult to secure sufficient turning and insertion space, and the stored object transfer mechanism tends to be long due to its deep depth. Another option is to take things in and out from the side of a shelf with a large number of items arranged in rows, but with this method, space for moving the transport device and stacker crane must be provided on the left and right sides of the shelf, and the shelf There are problems in that the space is small and equipment costs are high. As a device for solving these problems, a barrel-shaped object handling system disclosed in Japanese Patent Application Laid-Open No. 116577/1983 is known. This handling system is equipped with a long, horizontally extending rolling device support on the front of a running cart that runs on wheels on support rails, and a roller is attached to the lower end of the device via an arm that can be raised and lowered. The idea is to move the barrel-like object while rolling it by pushing the barrel. In this device, the rollers rise and fall, but they are not forced to rotate; instead, the barrel is propelled by the pressure of the rollers, and the rollers are rotatable (free) to reduce the friction with the barrel that occurs. It is something to do. Therefore, when rolling a heavy barrel with the rollers, the running cart receives a considerable reaction force via the rollers, and due to this reaction force, a large propulsion force is required to move the running cart, and the running cart also moves on the support rail. There was a problem that it slipped and could not be pushed firmly. The present invention solves these problems.

The gist of the present invention is to provide an inverted L-shaped frame consisting of a horizontal member that largely protrudes forward and a vertical member perpendicular to the horizontal member on the front surface of a traveling truck, and to force the lower tip of the horizontal member of the inverted L-shaped frame to A movable roller to be driven is attached via an arm that can be raised and lowered freely, and a cylindrical or barrel-shaped rolling element placed in the space below the horizontal member of the inverted L-shaped frame is mounted at a position conjugate with the movable roller and sandwiched therebetween. A freely rotatable free roller is attached to the vertical member of the inverted L-shaped frame, and the running wheels of the running truck and the machine are set so that the circumferential speed and direction of rotation of the movable roller are the same as the circumferential speed and direction of the rolling object. The present invention relates to a conveying device for a cylindrical or barrel-shaped rolling object, which is characterized by being electrically or electrically synchronized.

It goes without saying that the conveying device of the present invention can be used not only as a loading/unloading device in a narrow shelf as shown in FIG. be.

Embodiments of the present invention will be described below based on the drawings. In the figure, 1 is a running trolley, 2 is a horizontally protruding member of the frame, 3 is a pivot, 4 is an arm, 5 is a movable roller,
6 is a free roller, 7 is an air cylinder, 8 is a travel motor, 9 is a travel wheel, 10 is a barrel holder that also serves as a rail, 11 is a barrel, 12 is a wheel axle, 13, 14, 1
Numerals 5, 16, 17, and 18 are sprockets, and chain transmission is performed between the sprockets 13, 14, and 15 to rotate the wheel shaft 12 and drive the running wheel 9. On the other hand, sprockets 13, 14, 16, 17, 18
The idle gears 19 and 20 are transmitted by chain between
Rotate. Further, chain transmission is also carried out between the sprockets 21 and 22 to rotate the movable roller 5.
At this time, the sprocket ratio is selected so that the circumferential speed of the wheel shaft 9 and the circumferential speed of the movable roller 5 are the same. In this embodiment, the air cylinder 7 is extended to make the arm 4 horizontal, the movable roller 5 is retracted, the traveling carriage 1 is advanced, and it is stopped at a position where the free roller 6 almost contacts the barrel 11.

Next, the air cylinder 7 is retracted and the arm 4 is rotated to a position where the movable roller 5 almost contacts the barrel 11. In this state, when the traveling carriage 1 is moved backward, the movable roller 5 causes the barrel 11 to roll in the backward direction at the same speed as the traveling carriage 1. When the traveling truck 1 is moved forward, the barrel 11 is pushed by the free roller 6 and rolls in the forward direction.

As described above, according to the present invention, an inverted L
The frame is configured to form a shaped space, a movable roller that can be raised and lowered downward is provided at the end of the frame, the movable roller and a co-located roller are arranged, and the traveling wheels and the movable roller are arranged. By keeping the circumferential speed the same, the traveling cart can move in and out of the racks for storing cylindrical and barrel-shaped objects with narrow shelf spacing, capturing only one of these objects in a narrow space, and without slipping.
It can be transported smoothly and quickly by rolling, and since the transporting device of the present invention can be carried in and out by entering and exiting through the narrow opening of the shelf, the transporting device of the present invention can be easily transported even if the shelves are arranged in a continuous three-dimensional manner. It is possible to carry out stored items in and out using the shelf space without providing a dedicated space for the device, and it is possible to obtain the excellent effect that a continuous three-dimensionally arranged shelf with a narrow frontage and a high shelf space occupancy rate can be used. In addition, a movable roller that is forcibly driven and a rotatable free roller that is conjugated to the movable roller and are sandwiched therebetween keep in contact with a cylindrical or barrel-shaped rolling element and rotate and move the rolling element, so it is a conjugate roller. The horizontal force acting through the movable roller and the free roller cancel each other out, and only the pure rotational force (moment) from the movable roller remains to roll the barrel. The wheels of the traveling trolley do not slip, and the rolling object can be moved reliably with a small propulsive force.
