Description

Pallet collection apparatus for logistics circulation of logistics loading warehouse {pallet collection apparatus Technical circulation of cargoes in the freight-storage storehouse}

The present invention relates to a logistics circulation device of a logistics loading warehouse, and more particularly, to improve a circulation method and a recovery method of a pallet for logistics loading, and to propose a pallet recovery device for improving the circulation method and a recovery method of the pallet. ,

It increases the space utilization of the logistics warehouse, makes the loading and unloading of the logistics very simple, unloads and loads very quickly, reduces the operational maintenance costs, and reduces economic costs due to the reduction of management and workforce. Pallet recovery apparatus for the logistics circulation of the logistics warehouse with a very effective effect.

Logistics loading warehouse is a storage warehouse for temporarily or long-term loading and storing all goods used in daily life such as various foods, drinks, clothes, home appliances, etc. produced in large quantities in factories and production areas.

Therefore, such a warehouse is to store the mass-produced goods, and to distribute the quantity to the consumption area as required.

In addition, in the empty space of the warehouse caused by goods shipped to the consumption area, newly produced goods can be newly loaded to provide the goods to the consumption area promptly as needed, and also between the origin and the consumption area. Its role is to make it possible to deliver goods to consumers more quickly.

Such a warehouse loading warehouse should load or unload the loaded goods more quickly, and facilitate the loading and unloading operation while enabling the storage of a larger volume through the efficient use of the logistic loading space along with the quick loading and unloading. To be designed and constructed so that the priority is emerging.

Therefore, the design of a typical warehouse loading warehouse design a pallet rack having a width and a height in which vertical pallets can be put in and out as shown in Figs. 1 and 2, and vertically forklift or auto The pallets are loaded and stored in a palletized state by a crane, and they are stored in a single pallet system.In the case of unloading the cargoes in a loaded state, similarly, the logistics are loaded by forklift or auto crane. To be transported by the operator to the ground or to a transport vehicle.

If this is explained by the work flow chart shown in FIG.

If you want to fill up the pallet with the logistics in each storage room by forklift or auto crane, and unload some of the logistics in the loading state as necessary, unload workers on the forklift 100 or auto crane ( 101 is aboard the pallet storage room to be unloaded, and when the climb is completed, the worker withdraws the logistics box from the upper loading logistics of the pallet 102 to the forklift 100 or the auto crane as much as desired. After the necessary logistics have been withdrawn, the forklift or auto crane is lowered again and the withdrawn logistics box is to be moved to the place to be moved.

In addition, when this is described by a work flow diagram as shown in FIG.

If you want to fill the pallet with the logistics loaded in each storage room by forklift or auto crane, and unload some of the logistics in the loaded condition as necessary, the required logistics by the forklift 100 or auto crane The pallet loaded on the floor is lowered to the ground, and the logistics of the upper part of the pallet on the ground are unloaded as many times as the worker wants.The pallet loaded with the unloaded goods is removed by the forklift or the auto crane. To enter the storage room.

By this method, a pallet track having a plurality of vertical storage compartments is formed by a work method, and a forklift or an autocrane is formed on one side of the pallet track, respectively, so that the logistic in the state of being loaded by the forklift or the autocracker's up and down work is carried out. It will work to unload or store.

However, the conventional logistic loading warehouse as described above and a work method for circulating the same have the following problems.

Firstly, when the forklift or autocrane does the work of receiving the logistics, there is a problem in that the warehouse does not carry out the logistics work stored in the loading warehouse. In other words, each one of the forklift or autocrane performs the goods receipt and shipment of the logistics, so that the goods cannot be released during the goods receipt of the logistics. You must wait for the turn or unload to a temporary storage place.

Secondly, in order to load or unload the goods stored in the loaded and stored state, the worker has to work up and down together with the pallet while working on the forklift or auto crane. And because the work should be borrowed by the worker in the process of leaving the factory, workability is also very degraded.

Third, if the logistics in the pallet are completely lost due to the goods issue of the logistics, that is, if only empty pallets remain, the forklift or auto crane that posted the recovery work of the empty pallets separately from the goods receipt and delivery of the logistics. Because it must be carried out by the additional work time and personnel must be consumed additionally.

Fourth, since pallets are loaded and unloaded only in one direction, the first-in first-out products cannot be arranged in horizontal or plural rows in principle, and the front and rear areas consist of only one pallet space. Because each pallet rack occupies each pallet track and its corresponding forklift and its operating space and unloading space for each pallet rack, it occupies very much unnecessary space and is actually stored in comparison with its area. The amount of logistics is decreasing.

Thirdly, if you want to release several types of logistics at once, the worker and forklift or auto crane should be moved to various locations, and they must be released. As it is shipped, it takes a very long time to ship several kinds of logistics.

Logistics circulation method and design structure of the conventional distribution warehouse having the above problems have the above problems, but there is no countermeasure, so the utility value of the distribution warehouse is very high, even though the above problems are taken. This was possible.

The present invention was devised to eliminate the above problems,

While constructing a plurality of storage spaces while adhering to the principle of first-in, first-out, while only one side of the pallet rack is designed to carry out the receipt and pallet recovery operations, the other side of the pallet rack is designed to carry out only the logistics operations.

In addition to enabling faster goods receipt and release of logistics, the delivery of logistics was automatically moved from one side to the required location by means of a separate conveyor belt conveying means. By staying in the space, it is possible to keep the goods in stock at the same time as well as to continuously receive the pallets, and to provide pallet recovery equipment for the logistics circulation of the logistics warehouse, which is very fast and easy to collect the pallets. There is a purpose of the present invention.

As a technical means for achieving the object of the present invention as described above, pallet recovery means equipped with a pallet return device for entering and automatically transporting the pallet and discharged in the entering direction after the transfer, the usual forklift or auto crane and It is composed of a conveying means by a conveyor belt for automatically transporting the distribution box shipped.

The protrusion jaw 32 of the gibber (2) and hanging or separated and the support plate 4 is combined to be rotated downward and fixed.

In addition, the position fixing device 40 described above mounts the rotary lever 43 and the bending plate 41 by the bracket 42 on the other side of the gibber 2, and the bottom surface of the rotary lever 43 at the front end thereof. Hinge coupling of the end of the plate-shaped sliding bar 45 is formed in the engaging groove 44, the locking bar (47) is formed on the upper side of the gibber (2) where the locking groove 44 is located, the sliding bar ( The lower middle of the 45 and the lower portion of the bracket 42 is configured to be coalesced by the spring 46.

In addition, the reverse prevention device 50 is formed to be rotatable by the hinge shaft 52, the weight plate 51 on the bending plate on the upper side of the gibber (2), the weight of the lower than the upper portion of the hinge shaft 52 To form a heavier weight is configured to be inclined on the hinge shaft 52 by its own weight.

In addition, the pallet detection device 60 mounted on the end of the support plate 2 is rotatably mounted by the bracket 62 mounted on the support plate (2) 'L' shaped bending plate 61, the bending plate ( An extension rib 63 is formed at the lower portion of the lower portion 61, and the end portion of the extension rib 63 and the tip of the bracket 62 are coalesced by the spring 64.

Further, a stopper 71 on a bending plate is rotatably coupled to an intermediate portion of the connecting rod 8 mounted at the end of the recovery rails 7 and 7 'below the support rails 1 and 1'. The end of the stopper 71 is equipped with a weight 72, the bin pallet reverse prevention device 70 is formed so as to always enter by the weight of the weight (72).

Referring to the operation of the present invention pallet recovery system and recovery device by the above system and configuration in more detail by the accompanying drawings as follows.

As shown in FIG. 7, the pallet recovery device of the present invention is coupled to the gibber 2 fixed to the inner middle portion of the support rail (1) (1 ') formed in parallel spaced apart, by the gibber (2) It is divided into two sides.

In addition, a plurality of rotating rollers (3) (3 ') is mounted on the support rail (1) (1') is free to rotate inside the divided one side, the separate support plate 4 is mounted on the other side divided A plurality of rotating rollers 5, 5 'are mounted at both sides of the supporting plate 4, but are continuously connected to the rotating rollers 3, 3' of the supporting rails 1, 1 '. To form.

Accordingly, the rotary rollers 3 and 3 'mounted on the support rails 1 and 1' support the pallet 9 which is placed on top of the rotary rollers 3 and 3 'as fixed rollers. The pallet 9 is moved to one side by the rotation of the rotary rollers 3 and 3 '.

In addition, the plurality of rotating rollers 5 and 5 ′ mounted on both sides of the other supporting plate 4 support or move the pallet 9 in the same manner as described above, while the supporting plate 4 is rotated by the entire rotational lowering. It is to play a role to move the settled pallet (9) in the reverse direction.

In addition, the support rail (1) (1 ') described above is formed on the lower side of the rotating roller (5) (5') fixed to the support plate 4 than the fixed rotating roller (3) (3 ') side as a whole The pallet 9 is automatically moved to the side of the downward slope by the weight of the pallet 9 and the distribution box 10 at the upper part of the pallet as the support rails 1 and 1 'are inclined to one side. It is configured to be.

Therefore, the pallet 9 in the state in which the distribution box 10 is loaded by using a separate port lift 11 at the end of the fixed rotating roller 3 (3 ') side.

Therefore, the pallet 9 once entered is moved inward by the free rotation and the inclined surface of the rotary rollers 3 and 3 'fixed to the support rails 1 and 1'.

The pallet 9 in the state in which the distribution box 10 is loaded by this movement action is to be stored in two of the upper side of the support plate 4 and the end side of the fixed rail 1, 1 '.

In such a storage state, the user goes through a process of leaving the logistics box 10 of the appropriate quantity as needed, in this case, the logistics box 10 first-in-first-out in the other direction rather than the entry direction of the pallet 9 described above. It will be released first.

When all the distribution boxes 10 loaded on one pallet 9 are released by such a shipment operation, the pallet 9 becomes empty, so it is removed, and a new pallet 9 is entered into the rear side. It is necessary to proceed with the factory release, the removal or recovery of the empty pallet (9) will be described in more detail as follows.

First, as shown in FIG. 8, when the operation lever 23 mounted at the end of the support rail 1 is pushed in the direction opposite to the forward direction of the pallet 9, the support plate 4 is endd by the rotation shaft 6. Is lowered and rotated as shown in FIG.

Since the operating lever 23 must be operated only as necessary, there will be no problem that the pallet 9 in the state where the logistics box is loaded is returned, and thus, the switch rod 24 as shown in FIGS. 9 or 10 and 11 and The switch plate 26 is configured to enable the rotation of the operating lever 23 only when the user operates the switch rod 24.

When the actuating lever 23 presses the switch rod 24 mounted on the side of the bracket 21 to which the hinge is fixed, the switch rod 24 is lowered, and the end of the lowered switch rod 24 is a switch plate ( 26), the end of the lower switch bar 24 is positioned in the insertion hole 25 of the switch plate 26.

Therefore, when the operating lever 23 is pushed in the state in which the switch rod 24 is raised, the upper portion of the switch plate 26 that rotates together with the operating lever 23 is caught by the switch rod 24 and cannot rotate. On the contrary, when the operating lever 23 is pushed while the switch rod 24 is pressed down, the end of the switch rod 24 is inserted into the insertion hole 25 of the switch plate 26 so that the rotation of the operating lever 23 is prevented. It is possible.

Therefore, when the operating lever 23 is pushed in the state of stepping on the switch rod 24, it is to pull the switch rod 28 connected to the lower end of the operating lever 23, the switch rod by the operation of the switch rod 28 The rotary lever 27 mounted at the end of 28 is rotated.

When the rotary lever 27 rotates as shown in FIGS. 12 and 13, the intermittent plates 29 are symmetrically spaced apart by the springs 30 and 30 ′ in the upper and lower portions of the rotary lever 27. .

That is, when the electric switch rod 28 is mounted below the hinge point of the rotary lever 27, the rotary lever 27 and the intermittent plate 29 simultaneously operate in accordance with the operation of the switch rod 28. Will be rotated.

When the intermittent plate 29 rotates in this way, the protrusion jaw 32 mounted on one side lower portion of the gibber 2 and the locking jaw 31 at the end of the intermittent plate 29 are released, and the support plate 4 is rotated ( 6) is to rotate down to the axial point.

In addition, when the support plate 4 is raised by pulling the operation lever 23 again, the locking jaw 31 of the intermittent plate 29 and the protrusion jaw 32 of the gibber 2 are held by the holding force. The supporting plate 4 is to be supported so as not to descend.

In addition to the safety device by the switch rod 24 as described above, the rotary lever 27 and the intermittent plate 29 are connected by springs 30 and 30 ', and thus the springs 30 and 30'. By adjusting the tension of the), when the load to press on the upper portion of the support plate 4 is large, so that the intermittent plate 29 does not work, and added another safety device, which will be described in more detail,

When the rotary lever 27 rotates by the operation of the switch rod 28 described above, the spring 30, 30 'is tensioned by the rotational force, and the tensioned spring 30 is interrupted by the restoring plate. Will pull (29).

Therefore, the operation of the intermittent plate 29 by the elastic restoring force of the spring 30 will be operated in proportion to the total load including the support plate 4 of the upper portion, so if the locking step 31 of the intermittent plate 29 If the protruding jaw 32 of the gibber 2 and the tension force of the spring is greater than the rubbing friction force that is interlocked with each other by the upper load, the intermittent plate 29 will be activated and the supporting plate 4 can be lowered, and the upper load If the frictional friction force by the greater than the tensile force of the spring intermittent plate 29 will not operate.

That is, when only the holding force by the load of the rotating body including the support plate 4, the rotary rollers 5, 5 ', the empty pallet 9, etc. is caught by the latching jaw 31 and the protruding jaw 32 The tension of the spring 30 is set by the tension force of the spring 30 so as to operate the intermittent plate 29, the distribution box 10 on the upper portion of the support plate 4 and the pallet (9). ) Is loaded in the state that the load is increased, so the locking force applied to the latching jaw 31 and the protruding jaw 32 is relatively increased. ) Will not work.

Therefore, even if the operation lever 23 is pushed down while stepping on the switch rod 24 due to a user's error, when the distribution box 10 is loaded on the pallet 9, it is intermittent by the tension of the spring 30. Since the plate 29 is not operated, safer operation is possible.

Therefore, when the pallet 9 in the completely empty state is generated by such a double safety device, the actuating lever 23 is operated to cause the support plate 4 and the pallet 9 to rotate downward about the rotation shaft 6. will be.

In addition, at the same time as the support plate 4 rotates, one end of the recovery rails 7 and 7 'formed on one bottom surface of the support rails 1 and 1' is raised, and the ends thereof coincide with each other, and an inclined extension section is formed. Is to form,

The connecting rods 14 and 14 'of the rotary arm 13 mounted around the supporting angle 12 are respectively coupled to the ends of the supporting plate 4 and the ends of the recovery rails 7 and 7'. Therefore, when one side end of the support plate 4 is lowered, the connecting rod 14 on the support plate 4 side is lowered and presses and lowers one side of the rotary arm 13, and at the same time, the rotary arm 13 on which the other side rises. Is to raise one end of the recovery rail (7) (7 ') by the connecting rod (14').

Therefore, one side of the support plate 4 is lowered and one side of the support rails 7 and 7 'is raised, so that the support plate 4 and the recovery rails 7 and 7' are formed in a continuous inclined surface. (4) The empty pallet 9 on the upper side is moved downward along the inclined surface by the rotary rollers 5 and 5 'and is placed on the support rails 7 and 7' in a state where the movement is completed. Will be.

After the movement of the empty pallet 9 is completed, the raised portions of the support rails 7 and 7 'are lowered again by the weight of the empty pallet 9 to form a horizontal state as shown in FIG. 15. will be.

In addition, in accordance with the horizontal action of the support rails 7 and 7 ', the connecting rods 14 and 14' and the rotating arm 13 are rotated to have the force to raise the support plate 4, and this force Is to pull the operating lever 23 to raise the support plate (4) to help to return to the original state.

16 is a partially enlarged perspective view showing a position fixing device and a pallet detecting device according to the present invention,

Rotating lever 43 rotatably fixed to the side of the gibber (2) by the bracket 42 forms a separate axial point on the top coupled to the end of the sliding bar 45 formed thereon engaging groove 44 In addition, the fixed shaft of the rotary lever 43 is formed to form a bent plate 41 is bent upwardly, and the hook bar (47) is formed in the gibber (2) where the hooking groove 44 is located, the bending bar 47 is formed In the state where the plate 41 protrudes upward, the catching groove 44 and the catching rod 47 are locked to each other, and the lower portion of the sliding bar 45 and the lower portion of the bracket 42 are springs 46. It is to force the sliding bar 45 is always retracted by the restoring force of the spring 46, that is, by the resilience of the spring 46, so that the bending plate 41 is always maintained in an upward bent state.

The support plate 4 which moved the empty pallet 9 to the collection rail 7 and 7 'side in such a state pulls the operation lever 23, and the edge part of the support plate 4 protrudes on the side of the gibber 2 side. It is to be fixed to the jaw 32 to perform the work,

At this time, the pallet detection device 60 by the 'd' shaped bending plate 61 is operated so that the locking groove 44 of the sliding bar 45 is separated from the locking bar 47, the distribution box 10 The pallet 9 of the loaded load is automatically moved to the supporting plate 4 side along the inclined surface of the supporting rails 1 and 1 '.

Looking at this, in more detail,

As shown in FIG. 17, since the 'd'-shaped bending plate 61 is extended by the spring 64, the extension rib 63 and the bracket 62 at the bottom thereof have no load on the upper portion of the bending plate 61. If there is no sieve, the bending plate 61 is automatically raised to maintain the protruding state,

Since the support plate 4 does not have the pallet 9 at the top thereof, the bending plate 61 is raised in the state protruding from the top of the support plate 4.

Therefore, as the bent plate 61 is raised, the rear end thereof contacts the end of the sliding bar 45 and raises the end of the sliding bar 45, and the sliding bar 45 is moved upward by the upward rotation of the sliding bar 45. The locking groove 44 of the 45 is to be separated from the locking bar 47.

Therefore, the sliding bar 45 which is free to move forward and backward moves forward by the load of the pallet 9, and the bending plate 41 which supported the pallet 9 moves forward of the pallet 9 at the same time as forward movement. Is rotated in the direction.

Therefore, as the pallet 9 moves forward, the bending plate 41 rotates as shown in FIG. 18, and the sliding bar 45 moves forward as the bending plate 41 rotates.

As shown in FIG. 19, the pallet 9 continues to move while the bending plate 41 is completely rotated. As shown in FIG. 20, the end of the pallet 9 has a 'd' shaped bending plate 41. ), The spring 64 of the bending plate 41 is pressed along the inclined surface of the bending plate 41 so that the bending plate 41 is recessed in the support plate 4 so that it moves naturally.

In addition, since the pallet 9 moved to the upper side of the support plate 4 should not be reversed again and back, at this time, the pallet 9 is prevented from being reversed by the weight plate 51 formed in the gibber 2. Become,

That is, as the pallet 9 moves as shown in FIG. 21, since the pallet 9 is pressed and rotated by pressing the weight plate 51, it is possible to move naturally without friction or resistance. As described above, after the end of the pallet 9 has completely passed through the weight plate 51, the weight plate 51 having a relatively heavy bottom portion is vertically positioned about the hinge axis 52.

In this state of standing, even if the pallet (9) is retracted, the lower part of the weight plate 51 is caught by the gibber (2) can not be rotated because it is impossible to reverse.

In addition, as shown in FIG. 23, a reverse prevention device as described above is also formed in the middle portion of the connecting rod 8 mounted at the end of the recovery rails 7 and 7 '. It is an apparatus which prevents the backwards of the empty pallet 9 from which the box 10 is not loaded.

That is, when the empty pallet 9 moves forward as shown in FIG. 24, the inclined surface of the stopper 71 is pressed by the load of the pallet 9, and the empty pallet 9 is moved without difficulty. After the end of 9) passes through the stopper 71, the stopper 71 is placed by the weight of the weight 72 mounted on the lower part of the stopper 71.

Therefore, even if the empty pallet 9 is retracted by the stopper operation of the stopper 71, the stopper 71 is caught by the stopper 71 and no longer retreats.

In addition, when the recovery rails (7) (7 ') are raised by mounting the compression cylinder (16) at the intermediate portion of the support rail (1) (1') and the end of the recovery rail (7) (7 '). The lifting force is stored in the compression cylinder 16, and when the recovery rails 7 and 7 'are lowered, that is, when the support plate 4 is raised by pulling the operating lever 23, the compression force is increased. Since the support plate 4 is raised by the restoring force of the compression cylinder 16, the return by the rise of the support plate 4 can be made easier.

By this operation, it is possible to continually circulate the logistics and pallet recovery operation, the distribution box 10 to be shipped is mounted on the conveyor belt 17 formed for each layer of the pallet rack 18 is collected to the factory floor After it is delivered to the factory.
