Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an automated warehouse or the like, in which a load smoothly moves from a storage shelf to a conveyor or vice versa when carrying out or loading a stored load. The present invention relates to a load transfer device that can be transferred.

[Prior Art] When carrying out a load stored in an automated warehouse or the like, conventionally, as shown in FIG.
Is pushed from the storage shelf b toward the conveyor c, and the load a is pushed onto the conveyor c by its own weight and the upper guide e pressed downward by the spring d so that the load a can be transferred onto the conveyor c. The frictional force between the load a and the conveyor c is increased so that the load a is pulled onto the conveyor c and transferred from the storage rack b onto the conveyor c.

As another conventional device, as shown in FIG. 5, a plurality of rollers f are provided in the vicinity of the tip of the storage rack b to reduce the resistance force when the load a moves on the storage rack b. If the load a is pushed out until the tip of the load a gets on the conveyor c,
The leading end of the load a is pulled toward the conveyor c by the frictional force between the load a and the rear part of the load a moves on the roller f with low resistance so that the load a can be transferred onto the conveyor c. There are also things. In FIG. 5, g is a fall prevention material when the load a is stored.

Further, conventionally, there is also one in which an actuator dedicated to the upper guide is used to control the pressurizing timing.

[Problems to be Solved by the Invention] In the conventional apparatus shown in FIG. 4, the upper guide e is always lowered downward by its own weight and the spring d, and the height h is lower than the height H of the load a. Up to upper guide e
Is pushed down by the spring d, the upper part of the tip of the load a is pushed back against the upper guide e and resistance is added, and the load a is conveyed by the conveyor c.
When you get on the top, the front of the upper guide e tends to lower and the resistance increases. Therefore, install a roller in the pressing part of the upper guide e to prevent rolling in the opposite direction from rolling resistance instead of sliding resistance. Had to do. Since the direction of pressurization is oblique, it was necessary to send the pressurization timing so that the pressurization was made as directly as possible.

Next, in the conventional apparatus shown in FIG. 5, the cost increases as the storage amount of the load a on the storage rack b increases, and a mechanism for stabilizing the load a on the storage rack b is required. Further, in the method of controlling the timing of pushing the upper guide e downward with a dedicated actuator, the number of control points is increased, the structure is complicated, and the weight and the cost are increased.

An object of the present invention is to provide a highly reliable load transfer device having a simple structure and a light weight, which uses a function of a conveyor to move in a longitudinal direction so that an upper guide pressurizes a load in a timely manner. To do.

[Means for Solving the Problems] The present invention relates to a sliding conveyor that can move in the longitudinal direction,
The upper guide support post, which is erected on both sides of the center in the longitudinal direction of the slide-out conveyor and moves in the longitudinal direction of the slide-out conveyor along with the movement in the longitudinal direction of the slide-out conveyor, and the center of the upper guide support post at the upper guide swing shaft. An upper guide that is swingably supported and extends over substantially the entire length of the slide-out conveyor above the slide-out conveyor, and a fixed frame that is fixed to the ground on both sides of the slide-out conveyor at approximately the center of the longitudinal movement range of the slide-out conveyor, The cam roller is attached to the fixed frame and is located above the upper guide, and both ends are mounted on the upper surface near both ends of the upper guide and have a horizontal portion centrally located above the cam roller. Tilts down to a position lower than the cam roller. A cam plate having a portion, an upper spring receiver protruding from the upper end of the upper guide support post to both end sides of the conveyor, and both ends of the upper guide through the end of the upper spring receiver and the end of the cam plate. The load transfer device is provided with a spring that presses the vicinity downward.

[Operation] When the slide-out conveyor is at the center position of the longitudinal movement range, the cam roller and the cam plate do not come into contact with each other, and the upper guides are similarly pressed by the springs near both ends, so that the upper guide is held horizontally and swings. It is prevented.
When the slide-out conveyor moves in one direction in the longitudinal direction, the cam roller pushes up the cam plate at the position where the load rides on the tip of the slide-out conveyor, one spring is compressed and lifted, and the other end of the upper guide presses the other spring. The force pushes the load out onto the conveyor.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 1 is a slide-out conveyor, and a slide-out guide rail 3 is provided in the longitudinal direction below the conveyor frame 2 of the slide-out conveyor 1, and the slide-out conveyor 1 is a conveyor frame. It is possible to move in the longitudinal direction along with the slide-out guide rail 3 together with 2 and 2.

On both sides of the center of the slide-out conveyor 1 in the longitudinal direction, upper guide support posts 4 whose lower ends are attached to the conveyor frame 2 are provided upright. An upper guide swing shaft 6 in a direction perpendicular to the longitudinal direction of the slide-out conveyor 1 is attached to the upper guide support post 4 at a position slightly higher than the height of the load 5 placed on the slide-out conveyor 1. Above the slide-out conveyor 1, there is provided an upper guide 7 having a length extending over substantially the entire length of the slide-out conveyor 1, and the center of the upper guide 7 is swingably supported by the above-mentioned upper guide swing shaft 6. There is. Guide rollers 8 in a direction orthogonal to the longitudinal direction of the slide-out conveyor 1 are attached to both ends of the upper guide 7.

Gate-shaped fixed frames 9 whose lower ends are fixed to the ground and which straddle the upper guides 7 are erected on both sides of the center of the sliding guide rails 3 in the longitudinal direction. A cam roller 10 located slightly above the upper guide 7 and extending in a direction orthogonal to the longitudinal direction of the slide-out conveyor 1 is attached to the fixed frame 9 via a bracket 11.

Reference numeral 12 denotes a cam plate, the center of which is a horizontal portion 13 which is located above the cam roller 10, and the inclined portions 14 and 15 are continuous from both ends of the horizontal portion 13, and the tip of the inclined portions 14 and 15 is provided. Has horizontal ends 16 and 17 which are lowered one step. Inclined part 14,15
Is lowered from the portion connected to the horizontal portion 13 toward the end portions 16 and 17, and is at a position lower than the cam roller 10 at both ends. The ends 16 and 17 of the cam plate 12 are placed on the upper surface near the both ends of the upper guide 7.

From the upper end of the upper guide support post 4, upper spring receivers 18 and 19 project from the upper ends of the slide-out conveyor 1 so as to project toward both ends of the slide conveyor 1. This upper spring bridge 18,
Between the ends of 19 and the ends 16 and 17 of the cam plate 12, springs 20 and 21 having the same specifications are provided, and the upper ends of the springs 20 and 21 are supported by the upper spring supports 18 and 19. The lower ends of the springs 20 and 21 are supported by the end portions 16 and 17 of the cam plate 12,
Via the ends 16 and 17 of the cam plate 12, the vicinity of both ends of the upper guide 7 is pressed downward.

Springs and cam plate holding bars 22 and 23 are provided on the upper surface near both ends of the upper guide 7 so as to project upward.
The springs and the cam plate holding rods 22 and 23 penetrate the end portions 16 and 17 of the cam plate 12, the centers of the springs 20 and 21, and the upper spring receivers 18 and 19 to prevent the springs 20 and 21 from coming off. At the same time, the ends 16 and 17 of the cam plate 12 are prevented from slipping off from the upper surface of the upper guide 7.

In the above-mentioned apparatus, when the slide-out conveyor 1 is located at the center of the range where the slide-out conveyor 1 moves along the slide-out guide rail 3 as shown in FIG.
Is located above the cam roller 10 and is not in contact with it.
It is pressed evenly by and is kept horizontal without rocking. If the load 5 is placed on the slide-out conveyor 1 in this state, the height of the upper guide swing shaft 6 is set so that a gap 24 is formed between the upper surface height of the load 5 and the lower surface height of the guide roller 8. Is set.

When the slide-out conveyor 1 moves to the right from the position shown in FIG. 1 and approaches the storage rack 25 as shown in FIG.
The load 5 stored in 25 is pushed toward the slide-out conveyor 1, and the front end of the load 5 rides on the slide-out conveyor 1.

When the slide-out conveyor 1 moves, the upper guide support post 4 also moves together with the slide-out conveyor 1, but the fixed frame 9 remains stationary. When the upper guide support post 4 moves to the right with the slide-out conveyor 1, the upper guide 7 also keeps the horizontal position and the cam plate
Take 12 and move to the right. Early in this move,
The horizontal portion 13 of the cam plate 12 moves to the right without contacting the cam roller 10, but eventually the inclined portion 14 of the cam plate 12 contacts the cam roller 10 and is pushed up as shown in FIG. Become. Therefore, the end 16 of the cam plate 12 is
Although 20 is compressed and rises to separate from the upper guide 7, the cam plate 12 is pressed by the pressing force of the other spring 21.
Since the right end side of the upper guide 7 is pushed down via the end portion 17 of the upper guide 7, the upper guide 7 swings clockwise around the upper guide swing shaft 6. At this time, since the front end of the load 5 has already climbed onto the slide-out conveyor 1, the guide roller 8 presses the front end of the load 5 against the slide-out conveyor 1 to increase the frictional force between the load 5 and the slide-out conveyor 1, The load 5 is pulled by the slide-out conveyor 1 and transferred from the storage rack 25 onto the slide-out conveyor 1. When the slide-out conveyor 1 moves to the left, the upper guide 7 becomes horizontal and separates from the load 5 as shown in FIG. 1, and the load 5 is sent to the left by the circulation drive of the slide-out conveyor 1.

[Advantages of the Invention] In the conventional upper guide, as shown in Fig. 4, the load may be prevented from being transferred onto the conveyor. However, Fig. 3 shows that the front end of the load slides out and the upper guide is mounted on the conveyor. Since the load pushes the load, there is an effect that the transfer of the load is not hindered by the upper guide.

Further, when the slide-out conveyor moves to the center of the moving range, the upper guide is separated from the load, so that there is an effect that a frictional resistance force against the movement of the load is not generated between the upper guide and the load.

Furthermore, since the upper guide movement uses the power of the power source to move the slide-out conveyor, no additional device for electrical control is required, and since a cam plate is used, the direction of the pressing force and the timing of movement Can be mechanically controlled, the structure is simple, the cost is low, and an efficient device can be obtained.
