[0002]

2. Description of the Related Art Conventionally, a process of forming left and right side members, which are main bones of a truck chassis, is painted and baked after a pressing process and a welding process. Here, in the pressing process, it is necessary to suppress the production stoppage due to mold change to the minimum necessary. Therefore, in principle, after pressing a certain number of right (or left) side members of a certain model, Press the same number of left (or right) side members. However, if the press die is an assembly die,
After successively pressing the right (or left) side members of a plurality of similar models by changing a part of the mold, successively pressing the left (or right) side members of the corresponding models. Sometimes.

[0003] These side members collectively store the right competitor and the left competitor of the same vehicle type and store them, and supply them to a post-process in response to a request of a later assembly process. In the subsequent assembly process, the right and left side members are combined as a pair and welded.

[0004]

The conventional side member manufacturing process has the following problems and is not suitable for practical use. a) When the side members are moved for pairing after painting and baking, the coating film is scratched.

B) When taking out a necessary side member from the side members accumulated on the ground or floor, the unnecessary side member is temporarily moved to another place, and then the necessary side member is taken out. Since unnecessary side members need to be returned to their original locations, much time and effort is required.

C) The side members before pairing and the side members after pairing are temporarily stored in an automatic warehouse, and when the side members necessary for pairing are taken out of the temporary members, an automatic storage having a large storage capacity is required. Requires a warehouse. In particular, when using an automatic warehouse that stores two side members on one shelf in order to increase the storage efficiency of the automated warehouse, use one (one or two) side members before pairing in one shelf. From 1
It is necessary to take out only one book and take out only one of the side members (one or two) before pairing on the other side stored in another shelf, and make a pair,

5 is a chain 21- of each stage of the automatic warehouse 21
This is a detour device that conveys parts by bypassing the chain 3. In the case of the second embodiment, a chain having the same structure as the chains 21-3 in each stage may be used.

6 is a moving device for moving components from the detour device 5 to the alignment table 7, 7 is an alignment table for placing the components R and L side by side,
Reference numeral 8 denotes a conveyor for aligning and suspending and suspending the components R and L placed on the alignment table 7 together.

The length in the longitudinal direction of the component R (or L) of the automatic warehouse 21 is determined by the length of the component, and the width and height in the vertical direction are determined by the balance between the amount of the component to be stored and the construction cost. .

The interval in the longitudinal direction of the component R (or L) of the pillar 21-1 of the automatic warehouse 21 is longer than the maximum length of the component R (basically the same length as the component L), and the interval in the direction perpendicular to it. And the rigidity of the beam 21-2 is determined by the weight of the component placed on the chain 21-3.

The beam 21-2 supports the chain 21-3 and the components mounted thereon, and the chain sprocket 21
Support -4. The distance between the chains 21-3 in the longitudinal direction of the component R (or L) is determined by the rigidity of the component R (or L). The interval between the beams 21-2 in the height direction is determined by the height of the component R (or L), the diameter of the chain sprocket 21-4, and the thickness of the top plate of the chain 21-3.

A chain having an arbitrary height (the lowermost stage is preferable) among a plurality of chains 21-3 in the height direction is used as the detour device 5, and chains of other heights are used for the previously pressed parts. It is convenient to use it for temporary storage.

In the following, 20 parts R (hereinafter referred to as AR, the same applies hereinafter) of the vehicle type A are manufactured, followed by 35 BRs and C parts.
Production of 15 R, 15 CL, 35 BL, AL
The operation of each device when manufacturing in the order of 20 pieces will be described.

Here, it is assumed that each stage of the chain 21-3 can carry 15 components, and that ten such chains 21-3 are installed.
It is also assumed that the lowest chain among the chains 21-3 is used as the bypass device 5, and the other chains are used for temporary storage.

It is further assumed that the chains 21-3 other than the lowermost stage have a margin equal to or greater than the total number of parts temporarily stored here.

The part AR is welded to the press by the press 1 shown in FIG. 1 and is conveyed to the entrance of the automatic warehouse 21 by the conveying device 2, and is transferred by the moving device 3 onto the temporary storage chain 21-3 of the automatic warehouse 21. Are sequentially moved next to the parts already stored.

It may be assumed that another part (for example, Z) is already mounted on the chain 21-3, or that nothing is mounted on the chain 21-3. OK, but suppose nothing is listed for now.

The chain 21-3 at a certain stage is advanced in the horizontal direction by one every time one part AR is mounted by the moving device 3. Then, when the chain is stored to the limit that can be stored (here, 15 chains), it is mounted on the next stage chain 21-3. In this case, 15 ARs are placed on the upper stage of the lowermost stage, and 5 ARs are placed on the chain of the next stage. Next, 10 BRs are placed on the sixth chain, 15 BRs are further placed on the next chain, and 5 BRs are further placed on the next chain. Next, 10 CRs are placed subsequently, and the remaining 5 CRs are placed on the next chain.
The temporary storage is now complete.

Next, the parts CL, BL and AL on the opposite side are sequentially manufactured. First, every time the CL is transported one by one by the transport unit 2, the reverse direction when the chain 21-3 is temporarily stored is stored. To return the CR, BR, and AR, which have already been temporarily stored, to the mobile device 3.

That is, each time one CL is transported from the transport device, the moving device 3 alternately moves the transported CL and the CR that has been temporarily stored one by one to the bypass device 5 alternately.

There are two methods of arranging CL and CR one by one on the bypass device 5 alternately, that is, CL is put first or CR is put first. It is determined depending on the subsequent steps. When the CL is further placed first, the moving device 3 moves the CL on the transport device 2 to the bypass device 5 first, and then moves the CR temporarily stored in the chain 21-3 to the moving device 3. Moves to the bypass device 5. If the CR is placed first, the chain 2
The CR temporarily stored in 1-3 is moved to the bypass device 5 first, and then the CL on the transport device 2 is moved to the bypass device 5.

The bypass devices 5 are arranged alternately one by one.
L and CR are sequentially conveyed to opposite ends, and the moving device 6 on the opposite side transfers these paired parts CL and CR to each other.
It is moved to the alignment table 7 one by one or two at a time, and the conveyor 8 transports two CLs and CRs at once.

Here, an example is shown in which a chain is used as a transporting device as a pair with a temporary storage in an automatic warehouse. In addition to this, like a walking beam type device, both directions in a forward direction and a reverse direction are used. Any mechanism can be used as long as it can be transported.

(Time Chart) (FIG. 3) FIG. 3 shows a time chart when three types of parts A, B, and C are sequentially manufactured. The suffixes r and l represent “for right” and “for left”, “A”, “B”, and “C” represent the amount of incoming and outgoing goods per unit time with respect to the automatic warehouse 4, “ΣA”,
“$ B” and “$ C” represent the stock amounts of the respective parts in the automatic warehouse.

Here, the upper and lower sides indicate the incoming and outgoing per unit time of the incoming and outgoing units, respectively, starting from the end of the incoming of the component Ar on the right side of A to the incoming of the Al on the left side of A,
Further, the part B on the right side of B from the end of the part Al on the left side of A
The reason why there is an interval between the start of r and the like is to stop the operation of the press for changing the type of the press.

The parts Ar, Br, and Cr for the right are stored in the automatic warehouse, the parts Al, Bl, and Cl for the left are stored until they are stored in the automatic warehouse. Therefore, the stock quantity of the right-hand parts increases once, and the stock quantity does not change during the stoppage of the press until the stocking and pick-up of the left-hand parts start at the same time. Starts at the same time, the parts for the right are also released and are reduced accordingly.

The dashed line in the line of the stock quantity of the left part indicates that the quantity increases with entry and decreases with the exit, and the solid line indicates the resulting change in inventory quantity.

“ΣTotal” represents the total amount of stock of each part, and the total “ΣTotal” of each part varies depending on the relationship between the production amount of each part per unit time and the type change time. .

(Third Embodiment) (FIG. 6, FIG. 7, FIG. 8) Reference numeral 2 denotes a transport device for transporting pressed parts, and reference numeral 22 denotes a shift device for moving components on the transport device in a direction perpendicular to the transport direction. It is.

One of the parts R pressed first is temporarily stored in the storage facility 21, and the other part L pressed later is transferred on the transfer device 2, and is shifted by the shift 22 at right angles to the transfer direction. After moving, one of the components that has been temporarily stored earlier is sent back to the storage facility 21 and moved to the transport device 2 via the transport device 3 to form a pair on the transport device 2. Things.

The shift device 22 moves the components placed on the right side of the transport device 2 to the left without interfering with the transport operation of the transport device 2 and without interfering with the operation of the moving device 3. Its structure is a device that combines a lifting device that moves up and down from the lower side of the upper surface of the transporting device 2 to an upper side of the upper surface of the transporting device 2 and moves in the left direction to move to the left. Is also good. Here, as the elevating / lowering device, the rack and the pinion or the crankshaft may be rotated by a motor, or may be elevated by a hydraulic cylinder. Further, the chain and the chain sprocket may be rotated by a motor.

The shift device 22 may be a device that simultaneously moves up and down and traverse by rotating the crankshaft or the cam mechanism by a single motor or the like to perform an elliptical motion.

Here, the other part L pressed later is conveyed on the conveying device 2, and at the same time as being moved at right angles to the conveying direction by the shift device 22, the moving device 3 is temporarily Since one of the stored parts is moved up and down to the corresponding position of the storage facility 21, the operation time (cycle time) is short, but the cost of the shift device 22 is required.

(Fourth Embodiment) (Shift device 22 is omitted in FIGS. 6, 7, and 8) As another embodiment, a method and an apparatus in which the shift device 22 is omitted in FIGS. 6, 7, and 8 are described. Suggest.

In this case, one of the parts that has been temporarily stored first is taken out of the storage facility 21 and moved by the moving device 3 to the opposite side of the moving device 3 of the transport device 2. Then, the other part L pressed later is conveyed on the conveying device 2, and is moved by the shift device 22 at right angles to the conveying direction to form a pair from the two components on the conveying device 2. be able to.

However, in this embodiment, unlike the case of the third embodiment, the moving device 3 is pressed later to unload one of the components stored in the storage facility 21 and then moves over the transport device 2. Since it is necessary to move the other component L that has been transported at right angles to the transport direction, the operation time (cycle time) becomes longer. Instead, the expense of the shift device 22 is eliminated.

In this example, the production amount per vehicle of one type is 5 to 100 units, and the production amount per unit time is about 80 units / H. The remodeling time is about 8 minutes / time and the number of times of remodeling is about 25 times / day. At this time, the inventory of the automatic warehouse 4 in front of the paint baking furnace 9 is up to 15
In the first embodiment, the rack 4-2 is not required, and only the stacker crane 4-1 and the rack 4-3 are used. It is about 25m wide and 11m high.

In the second embodiment, the stacker crane 4-1 as in the first embodiment is unnecessary in front of the coating baking furnace 9, so that the length is about 7 m, the width is about 13 m, and the height is 7 m.

The automatic warehouse 11 after the paint baking furnace 9
In order to respond to the production speed of the assembly process at the chassis assembly factory, approximately 500 pairs (1,000 pieces), equivalent to 4 days of inventory
The first embodiment has a shelf of about 27 m, a width of about 25 m, and a height of about 11 m, including the passage of the stacker crane.

In the present invention, the transport device 2 does not merely transport one component, but also shifts the component L in a direction perpendicular to the transport direction, and then transfers another component R from the storage facility 21. In order to have a width of two.

The shift device 22 moves the components conveyed to the conveyance device 2 in a direction perpendicular to the conveyance direction. Further, depending on the press production plan (when the part L is manufactured first and the part R is manufactured later), the part moved by the moving device 3 from the storage facility 21 to the transfer device 2 is moved in a direction perpendicular to the transfer direction. May be moved to.

Here, the transfer direction of the transfer device 2 is a direction perpendicular to the direction in which the transfer device 2 and the storage facility 21 are arranged with the moving device 3 interposed therebetween, but it is not always necessary to stick to this direction. After being carried in and forming a pair, it may be carried out in the direction opposite to the storage facility with respect to the moving device 3.

[0071]

According to the present invention, a pair of parts (R or L) on one side is temporarily stored in an automatic warehouse before painting,
Depending on the supply of the other parts (L or R) before painting,
A part (R or L) and another part (L or R)
Since the right and left parts are arranged alternately one by one according to the type of the temporarily stored parts (R or L), pairs can be easily assembled. As a result, a) the coating film is not damaged.

B) Unnecessary parts are temporarily moved to another place, and then necessary parts are taken out. Then, unnecessary parts are taken out, as in the case where necessary parts are taken out of the parts accumulated on the ground or floor. There is no need to return to the original place, so much time and effort are not required.

C) The parts before pairing and the parts after pairing are temporarily stored in separate automatic warehouses, and when the parts necessary for pairing are taken out of them, an automatic warehouse with a large storage capacity is required. It becomes unnecessary. In particular, when using an automatic warehouse that stores two parts on one shelf in order to increase the storage efficiency of the automatic warehouse, one of the parts (one or two) before pairing in one shelf is used. Take out just one and take it out of the other unpaired (one or two) parts stored on the other shelf
There is no need to take out only one and form a pair, and a machine with a complicated structure for automatically performing the operation is not required. Further, it is easy to arrange the right part and the left part in a correct order to form a pair, and the time taken out for pairing is reduced. Therefore, according to the present invention, after a plurality of types of parts are manufactured, when the parts are combined as a pair, the parts can be assembled easily and efficiently.

In the present invention, since the moving device 3 does not need to move the part L to be pressed later, but only moves the temporarily stored part R, it can be operated in a short cycle time, and can be operated in a short cycle time. A pairing operation corresponding to the manufacturing pitch can be performed. In addition, the moving device 6 and the alignment table 7
Is not always necessary. However, in that case, the conveyor 8 needs to be of a type that is scooped up from the transfer device 2.

In the fourth embodiment, the moving device 3 is not required.
