[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a pallet packing device.

[0002]

[Prior Art]

 Generally, when loading and unloading in a warehouse, if the forklift mounted on the forklift or the loads on the forklift are uneven, it is difficult to stack them. When storing luggage, if the luggage extends from the pallet, the sensor will mistakenly detect it.

Japanese Utility Model Laid-Open No. 63-130426 has already been proposed as a pallet load balancing device useful for solving such a problem.

In this known device, due to its structure, the middle part of the L-shaped arm arm (6) which is symmetrically opposed to each other is pivotally attached to the fixed base (1) by the support shaft (7), and each of them is pivoted. One end of the arm arm (6) is slidably engaged with the table (5) along the left-right direction, while the other end is also supported by the outer lower frame member (4) of the side plate (3). It is pivotally attached by a shaft (8).

Also, a left and right pair of double link arms (9) separate from the arm arm (6) is provided, and one end of each link arm (9) is also supported on the fixed base (1) as a support shaft. While being pivotally attached via (11), the other end is also pivotally attached to the outer lower frame member (4) of the side plate (3) by another support shaft (10).

That is, the arm arm (6) and the double link arm (9) form the entire four-bar linkage mechanism through the four support shafts (7), (8), (10) and (11). It is shaped so that when a load is loaded on the table (5), the side plate (3) moves in an arc around its support shafts (7) (11) and is pulled toward the load. There is. Therefore, it can be said that there is an advantage that a power source such as a motor is not required.

[0007]

[Problems to be solved by the device]

 However, in the case of the above-mentioned known device, in order to support the side plate (3) from below, a double link arm (9) is necessary in addition to the armature arm (6), and two types of arms (6) are also required. Since (9) must be linked correctly, the design of the working length and fulcrum position is complicated and difficult.

The side plate (3) is usually made of steel and integrated in a frame of at least about 1400 × 1030 mm, but the large weight of the side plate (3) and the double link arm (9). The table (5) does not sink and therefore the side plate (3) does not sink unless a heavier or larger load is loaded, since it is acting directly on the table and is pulled downward by the spring (12). Also does not move in an arc, and it is not possible to align the loads, and excessive stress is concentrated on the support shafts (7) and (11) for mounting the arms (6) and (9) to the fixed base (1). Therefore, there is also the problem of poor durability.

Furthermore, the table (5) is only supported from below by the pair of left and right lever arms (6), and the side plate (3) moves in an arc through the lever arms (6). Therefore, it is difficult to apply the configuration as a single-opening type load aligning device in which either the left or right side plate (3) is fixed, regardless of what is called a double-opening type load aligning device. Is.

[0010]

[Means for Solving the Problems]

 The present invention intends to improve such a problem, and for that purpose, a lifting table for receiving a pallet arranged in the central portion of the mounting table, and a plurality of pedestals integrally suspended from the table are provided. In order to receive each pedestal so that it can be lifted and lowered, the pedestal support stays that are attached integrally to the corresponding positions of the installation base, and the lower surface of the table and each support stay to press and urge the above table constantly in the floating direction. A compression coil spring interposed between the upper surface and the upper surface, a fixed back panel integrally erected from the installation base so as to face the back of the table, and the lower position of the table are traversed in the left-right direction. As described above, at least a pair of front and rear slide guide rails arranged in parallel on the upper surface of the installation stand, and a pair of left and right slide side panels sandwiching the table, and From the lower end of the side panel, the horizontal support bar extending integrally along the slide guide rail from the lower end to the rear, and a plurality of shafts supported by the horizontal support bar so as to roll on the upper surface of the guide rail. It consists of a wheel and at least a pair of left and right seesaw arms that interlock the side panels and tables, and each seesaw arm is pivotally attached to the installation base by a midpoint fulcrum shaft orthogonal to the slide guide rails. Similarly, the slide guide elongated hole formed at one end of each seesaw arm is loosely engaged with a pivot pin that integrally projects from the horizontal support bar of the slide side panel, while the other end of each seesaw arm is pivotally supported. When the roller is engaged rotatably with the lower surface of the table and the table sinks under the weight of the pallet, It is characterized in that the pair of left and right slide side panels are set so as to simultaneously advance and slide in the direction in which the table exists so that a pair of left and right slide side panels sandwich the pallet on the table via a seesaw arm that swings accordingly. It is a thing.

[0011]

[Action]

 According to the above configuration of the present invention, when the pallet (M) is carried onto the table (15) by the forklift, the table (15) receives the gravity of the pallet (M) and sinks. Since the seesaw arm (31) which is in solidarity with the table also swings around the midpoint fulcrum shaft (32), the pair of left and right slide side panels (19) are moved along the slide guide rail (14) at the same time all at once on the table (15). It will be pulled in the direction of sandwiching the upper pallet (M). As a result, the pallet (M), in combination with the fixed back panel (12), can be quickly and automatically aligned.

In that case, both of the side panels (19) are stably supported from below by the slide guide rails (14), and the weight of the panels (19) themselves is the seesaw arm (31). Since it does not act on the table and the table (15) at all, even if only a small amount of the pallet (M) is placed on the table (15), the aligned state can be surely achieved.

As a result, in combination with not requiring a special actuation source for both side panels (19), it is difficult to be restricted by design, and the midpoint fulcrum shaft (32) of the seesaw arm (31) is excessively large. It is possible to prevent the concentration of various stresses and improve the durability of the entire device.

On the other hand, when the pallet (M) is carried out from the table (15), the table (15) is automatically returned to the initial floating state due to the pressing force of the compression coil spring (18). The pair of left and right slide side panels (19) are also simultaneously retracted from the table (15) through the seesaw arm (31) that swings in a solid manner, and the mutual distance (W) facing each other is expanded. Therefore, it is possible to obtain a suitable waiting state for the next pallet loading operation.

Further, although the lower end of the table (15) is engaged with the other end of the seesaw arm (31) via a roller (36), a plurality of pedestals (16) separate from this are engaged. Since the table (15) is stably supported by the installation table (11) by means of the compression coil spring (18), one of the side panels (19) is used as a fixed side panel (19a). By erected integrally from (11), it is also possible to apply and implement the pallet load balancing device as a so-called single-open type.

[0016]

【Example】

 The specific construction of the present invention will be described in detail below with reference to the illustrated embodiment. In FIGS. 1 to 5 showing the whole of the pallet load balancing device, (11) is a channel-shaped steel and an entire quadrangle in plan view. In the frame, a required number of reinforcing bars (11a) made of beam channel steel are inserted in the frame so as to extend in the left-right direction.

(12) is a fixed back panel integrally erected from the center of the rear end of the installation base (11), and (13) is a frame for reinforcing the back of it, which is framed from a channel steel. There is. Similarly, (14) is a pair of front and rear slide guide rails fixedly laid on the upper surface of the installation base (11), both of which are made of horizontal H-shaped steel and extend in parallel along the left-right direction. ..

(15) is a quadrangular pallet receiving lift table arranged in the center of the installation table (11), which has an inverted U-shaped cross section, and its four corner positions are each leg. A pillar (16) is integrally suspended. (17) is a pedestal support stay integrally attached to the above-mentioned installation stand (11) or its reinforcing bar (11a) in a corresponding state of corresponding to each pedestal (16) of the table (15). There, each pedestal (16) is vertically pierced.

Moreover, a compression coil spring (18) interposed between the lower surface of the table (15) and the upper surface of the support stay (17) is wound around each pedestal (16). As shown in FIG. 1, the coil spring (18) constantly urges the table (15) so that the table (15) is lifted and returned.

Further, (19) is a pair of left and right slide side panels which stand upright in parallel so as to sandwich the table (15), and (20) is a frame which reinforces the back of each side panel (19). , The frame is integrated from square steel pipe. (20a) is a part of the frame (20), and the front and rear are integrally projected backward from the lower end of each side panel (19) along the upper surface of the slide guide rail (14). It is a pair of horizontal support bars, and the projecting tips thereof and the upper ends of the side panels (19) are connected and integrated via respective inclined braces (20b).

A plurality of wheels (21) attached to the horizontal support bar (20a) of each side panel (19) are adapted to roll on the upper surface of the slide guide rail (14). There is. Reference numeral (22) is a support shaft for each wheel (21), and reference numeral (23) is a bearing frame, which are fixedly integrated with the lower surface of the horizontal support bar (20a). Similarly, (24) is a pivot pin that extends through the horizontal support bar (20a) of each side panel (19), and is fitted to one end of a seesaw arm described later. (25) shows a retaining pin of the pivot pin (24), (26) shows a washer, and (27) shows a collar.

Further, (28) is a pair of left and right stoppers fixed to both ends of each slide guide rail (14), and prevents the side panel (19) from slipping off. Similarly, (29) is a plurality of skirt pieces integrally suspended from the horizontal support bar (20a) of each side panel (19), and the roller (30) pivotally supported at the lower end of the skirt piece has the above horizontal direction H. By being engaged with the slide guide rail (14) made of shaped steel from below, the side panel (19) is prevented from being inadvertently lifted.

The lifting table (15) and the slide side panel (19) are pivotally connected to each other via a pair of left and right seesaw arms (31) as described below, so that the table (15) is mounted on the table (15). When the pallet (M) is loaded, both side panels (19) are attracted to the central part where the table (15) is located at once, so that the side panels (19) are solidified with the sinking action of the table (15). It is designed to be able to slide.

That is, there are a total of four seesaw arms (31), and as shown in each of FIGS. 6 to 10, each is assembled and integrated from a pair of front and rear steel arm plates (31 a) forming a hook shape in a front view. Since the slide guide rails (14) are sandwiched by the both arm plates (31a), there is no risk of the side panel (19) derailing in the front-rear direction from the rails (14).

Reference numeral (32) is a pair of left and right fulcrum shafts that horizontally penetrate the middle portion of the seesaw arm (31), and both front and rear ends thereof are mounted on the mounting table (11) or the bearing flange (33). It is supported by the reinforcing bar (11a). The seesaw arm (31) swings around the midpoint fulcrum shaft (32). Reference numeral (34) is a bearing collar of the fulcrum shaft (32), which is inserted between the front and rear of the arm plate (31a).

Further, (35) is a slide guide elongated hole which is also formed at one end of the seesaw arm (31), and has a pivot guide penetrating the horizontal support bar (20a) of the side panel (19) therein. The projecting ends of the support pin (24) are slidably engaged with each other.

Reference numeral (36) is a roller attached to the other end of the seesaw arm (31) via a support shaft (37), and receives a biasing force of the compression coil spring (18) and a table (15). When it engages with the lower surface of the table, the table (15) rolls in the left-right direction as it moves up and down. It is clear from FIG. 9 that the support shaft (37) of the roller (36) also horizontally penetrates both arm plates (31a). Reference numeral (38) shows a bearing collar interposed between the front and rear of both arm plates (31a), (39) shows a fixed nut, and (40) shows a washer.

Although one roller (36) is attached to one end of the support shaft (37) in the figure, a pair of front and rear rollers (36) may of course be attached to both ends thereof. Further, when embodied as a large-sized pallet load arranging device, the slide guide rail (14) and the corresponding horizontal support bar (20a) of the slide side panel (19) and inclined braces are provided. (20b), wheels (21), seesaw arms (31), etc. can be increased in number.

In using the present invention having the above-described structure, the pallet (M) on which the luggage is loaded and the pallet (M) that is empty are loaded onto the table (15) by a forklift (not shown). .

Then, the table (15) receives the gravity of the pallet (M) and sinks as shown by the arrow (D) in FIG. 11, and the seesaw arm (31) solidified with the table (15). Since it swings around the midpoint fulcrum shaft (32), a pair of left and right slide side panels (19) are moved along the slide guide rail (14) at the same time as shown by the arrow (P) in the figure. 15) It will be drawn in the direction of sandwiching the upper pallet (M). As a result, the pallet (M), together with the fixed back panel (12) as shown in FIG. 12, can be quickly and naturally aligned.

In that case, both side panels (19) are both stably supported from below by the slide guide rails (14), and the weight of the panels (19) themselves is the seesaw arm (31). Since it does not act on the table and the table (15) at all, even if only a small amount of the pallet (M) is placed on the table (15), the aligned state can be surely achieved.

As a result, combined with the fact that no special actuation source for both side panels (19) is required, design restrictions are less likely to occur, and the midpoint fulcrum shaft (32) of the seesaw arm (31) is excessive. There is an advantage that various stresses can be prevented from concentrating and the durability of the entire device can be improved.

On the other hand, when the pallet (M) is carried out from the table (15), the table (15) is automatically lifted by the pressing force of the compression coil spring (18) as shown in FIGS. The pair of left and right slide side panels (19) are simultaneously retracted from the table (15) at once through the seesaw arm (31) that returns to the original state and swings in unison with this, and the mutual distance between them facing each other. Since (W) is expanded, a suitable waiting state for the next pallet loading operation can be obtained.

As is apparent from the above description, the other end of the seesaw arm (31) is engaged with the lower surface of the table (15) through the roller (36), but this is not the same. Since the table (15) is stably supported by the mounting base (11) by the plurality of pedestals (16) and the compression coil spring (18), the side panel (see FIG. 13) is suggested. It is also possible to carry out the application of the pallet load balancing device of the present invention as a so-called single-opening type by vertically arranging either one of them as a fixed side panel (19a) from the installation base (11). Is.

When embodied as a single-opening type, for example, a fixed back panel (12) facing a rectangular table (15) is erected as an inverted V-shape in plan view, while a slide side panel (19) is provided. It is also conceivable to design one as a V-shaped member facing this and to make it slide back and forth from the direction along the diagonal of the table (15) to the table (15).

[0036]

[Effect of the device]

 As described above, in the pallet arranging apparatus of the present invention, due to its structure, the pallet receiving lifting table (15) arranged at the center of the installation table (11) and the pallet receiving and lifting table (15) are integrally hung from the table. A plurality of pedestals (16), a pedestal support stay (17) integrally attached to a corresponding position of the installation base (11) so as to receive each pedestal (16) in a vertically movable manner, and the table ( 15) The compression coil spring (18) interposed between the lower surface of the table (15) and the upper surface of each support stay (17) so that the table (15) is always biased in the floating direction, and the table (15). The fixed back panel (12) integrally erected from the installation base (11) so as to face the back of the table and the installation base (11) so as to traverse the lower position of the table (15) in the left-right direction. Parallel to the upper surface of At least a pair of front and rear slide guide rails (14) installed, a pair of left and right slide side panels (19) sandwiching the table (15), and rear sides from the lower end of each side panel (19). The horizontal support bar (20a) integrally extended along the slide guide rail (14) and the horizontal support bar (20a) so as to roll on the upper surface of the guide rail (14). It comprises a plurality of supported wheels (21) and at least a pair of left and right seesaw arms (31) for interlocking each side panel (19) and table (15). Each of the seesaw arms (31) is a slide guide. An intermediate fulcrum shaft (32) orthogonal to the rails (14) pivotably attaches to the installation base (11) and at the same time each seesaw arm (31). The slide guide elongated hole (35) formed at one end is loosely engaged with a pivot pin (24) that integrally projects from the horizontal support bar (20a) of the slide side panel (19), and each seesaw arm (31) A roller (36) pivotally supported on the other end is rotatably engaged with the lower surface of the table (15) so that the table (15) receives the load weight of the pallet (M). When it sinks, a pair of left and right slide side panels (19) pinch the pallet (M) on the table (15) via a seesaw arm (31) that swings accordingly, so that the table (15) is moved. Since it is set to slide into the existing direction at the same time, there is an effect that the problems of the prior art mentioned at the beginning can be remedied.

That is, the slide side panel (19) of the present invention is stably supported from below by the slide guide rail (14), and the weight of the panel (19) itself is the seesaw arm (31) or the table. In contrast to (15), since it does not work at all as a load, even if only a small amount of pallet (M) is loaded on the table (15), the aligned state of the pallet (M) can be reliably achieved. it can.

The slide side panel (19) rolls on the upper surface of the slide guide rail (14) by means of wheels (21) and slides on and off the table (15). Therefore, there is no possibility that the excessive stress locally acts on the midpoint fulcrum shaft (32) of the seesaw arm (31), and therefore the durability strength of the entire device can be significantly improved. .

Further, a plurality of pedestals (16) are integrally suspended from the table (15), and each pedestal (16) can be lifted and lowered by a support stay (17) of the installation base (11). Since the table (15) is stably supported by the table and is compressed and biased by the compression coil spring (18) wound around each pedestal (16), the table (15) always floats. Even a so-called single-open type pallet load arranging device having the structure of 2 has an effect that it can be easily applied and embodied.

In particular, if the construction of claim 3 is adopted, it is possible to prevent the oscillating movement of the seesaw arm (31) and also the slide side panel (19) along the slide guide rail (14). It can be said that it is very profitable because it can perform the accurate and smooth forward and backward sliding action.
