2. Description of the Related Art The present applicant has previously filed Japanese Patent Application No. 3-343174.
For example, a cutting device for cutting a large-sized thin plate such as a tin plate or a tin-free steel plate into a body blank (hereinafter referred to as "blank") for forming a can body of a predetermined size and a cylinder for the blank. We have proposed a transport device for transporting the blank between a body maker and a blank-shaped can body. The apparatus includes a blank loading device that stacks a predetermined number of blanks formed by the cutting device and loads the blank as an integrated blank, a plurality of buckets on which the integrated blanks loaded by the blank loading device can be mounted, and those buckets. Is provided in the conveyance direction of the stacking blank, and a blank dispensing device that dispenses the stacking blank from the bucket at the end of the transporting conveyor and supplies the stacking blank to the body maker. That is, the carrying device is configured to continuously move a plurality of buckets, on which the integrated blanks loaded by the blank loading device are loaded, from the starting end portion to the terminating end portion in the blank feeding direction by the feeding conveyor. Is. Thus, the bucket prevents the stacked blanks from collapsing, and the stacked blanks can be transported at high speed.

A blank feeding device 80 used in this type of conveying device is, for example, as shown in FIG.
A stackable blank holding member 82 for stacking and holding a predetermined number of blanks W sent from the cutting device 81,
A feeding roller 83 that receives the stacking blank W ₃ in a stacked state by lowering the stacking blank holding member 82 and sends out the stacking blank W ₃ from the stacking blank holding member 82, and the stacking blank together with the sending roller 83. Slidable integrated blank support member 8 for supporting W ₃
4, the swing arm 86 to slide in the dispensing direction of the integrated blanks W ₃ of the integrated blank support member 84 by driving the cylinder 85, the integrated blank W ₃ paid out by the swing arm 86, the conveyor A feeding roller 89 that feeds toward a bucket 88 that stands by on 87,
A drive motor 90 for rotationally driving the charged roller 89 in the charging direction of the integrated blank W _3, together with the integrated blanks W ₃ which is introduced into the bucket 88 accurately guided in the direction of the bucket 88 by the closing roller 89, the integrated blanks W
A guide roller 92 for lowering the support of the stacking blank W ₃ by descending by the cylinder 91 after the ₃ is stored in the bucket 88 is provided. Further, when the holding member 82 holds the stacking blank W ₃ sent from the cutting device 81, a contact plate 93 is provided which contacts the side of the stacking blank W ₃ and arranges the stacked state. The contact plate 9
The cylinder 3 is reciprocated by the cylinder 94. Further, when the stacking blank W ₃ is stored in the bucket 88, there is provided a contact plate 95 that contacts the side of the stacking blank W ₃ and arranges the stacked state. The abutting plate 95 is vertically projectable by the cylinder 96 and is moved in the abutting direction by the cylinder 97. The contact plate 95 is
When integrated blank W ₃ is turned in the bucket 88 is positioned thereabove without interfering with integrated blank W _3, integrated blank W ₃ is brought into contact with integrated blank W ₃ descends after being put into the bucket 88 . This allows
The stack blank W ₃ is mounted in the bucket 88 while maintaining the stack state.

By the way, the processing speed of the cutting device 81 is relatively high, and the transfer speed of the bucket 88 on the transfer conveyor 87 is relatively high, but the processing speed and the transfer speed are not lowered. Also, it is desirable that the stacking blank W ₃ is loaded from the cutting device 81 into the bucket 88 at a high speed corresponding to the processing speed of the cutting device 81.

However, according to the stacking blank loading device 80, the stacking blank W ₃ transferred from the stacking blank support member 84 to the loading roller 89 is loaded into the bucket 88 by the loading roller 89. At this time, the blanks W forming the integrated blank W ₃ may be displaced from each other to cause a load collapse. That is, for example, when the blanks W are stacked, the coating film applied to the surface of the blanks W is slippery, the weight of the blanks W is small, and air is easily stagnant between the blanks W that are vertically stacked. , such a state of the integrated blanks W ₃ when transferring only the closing roller 89 is preceded as blank W located at the lowest portion of the integrated blank W ₃ is scooped, the portion of the stacked blanks W ₃ The blank W located is delayed from the blank below and the collapse of the stacked blank W ₃ occurs. For this reason, it is necessary to set the driving speed of the feeding roller 89 to a relatively low speed so that the load of the stacking blank W ₃ is not collapsed.
Wherein the addition rate of the integrated blanks W ₃ to 8 cutting device 81
However, there is a problem in that the efficiency cannot be reduced because the processing speed cannot be met.

Further, the integrated blank feeding device 80 is
The stack blank holding member 82 is lowered to collect the stack blank W ₃
Since the cutting device 81 cannot send the blank W to the integrated blank holding member 82 while it is being sent to the roller 83, the forming process of the blank W by the cutting device 81 must be interrupted. Therefore, there is an inconvenience that the processing speed of the cutting device 81 must be reduced.

Further, when a plurality of buckets 88 are arranged on the transfer conveyor 87 at a predetermined interval, each blank W when sent out from the cutting device 81.
It may not match the spacing between them. In such a case, there is a demand for a charging device that can quickly match the interval between the stacking blanks W ₃ held by the stacking blank holding member 82 with the interval between the buckets 88.

When the holding block 40 holds the integrated blank W ₃ ,
As shown in FIG. 5C, each support plate 20 is retracted to open the downward direction of the integrated blank W ₃ . As a result, the integrated blank W ₃ is held only by the holding block 40, and the delivery of the integrated blank W ₃ from each support plate 20 to each holding block 40 is completed. Each holding block 4
As described above, 0 is the inclined portions 44 and 45 and the holding plate 4
6 holds the integrated blank W ₃ in a state in which the collapse of the load is prevented.

Then, as shown in FIG. 5D, each holding block 40 holding the integrated blank W ₃ is lowered.
After each holding block 40 descends, the supporting plate 20 that has been retracted advances to the blank W delivery position, as shown in FIG.
As shown in FIG. 2, the blank W sent from the cutting device 1 is ready to be supported.

The forward and backward movement of each support plate 20 and each protection as described above.
Integrated blank W on holding block 40 ₃The delivery of the above
Performed within the non-delivery time of the blank W from the cutting device 1
Be done. Thereby, the blank W is sent from the cutting device 1.
It is not necessary to intentionally interrupt the cutting, and the cutting device 1 can be processed at high speed.
It is possible to maintain the physical condition.

Then, while the holding blocks 40 are descending,
The spacing means 47 allows spacing between the holding blocks 40. That is, as shown in FIG.
By extending the piston rod 54 of the cylinder 53, the sliding rod 49 is slid so that each guide member 5
0 is brought into contact with each step 49a of the sliding rod 49 to form a predetermined space between the holding blocks 40. The interval at this time corresponds to the interval between the buckets 3 on the transport conveyor 2.

Thereafter, each holding block 40 holds the integrated blank W ₃ and further descends. Next, in the course of this descent, as shown in FIG. 7, the accumulation blank W ₃ on each holding block 40 is guided by the guide roller 57 of the transfer path 56.
And at the same time, the engaging portion 6 of the pushing member 59.
0 locks the lower part of the rear end side of the integrated blank W ₃ .

Each holding block 40 continues to descend to a position where it does not interfere even after the integrated blank W ₃ is delivered to the rollers.

Subsequently, the stacking blank W ₃ is locked to the locking part 60, and the contacting part 61 integral with the locking part 60 is in contact with the rear end side of the stacking blank W ₃ and is extruded. The member 59 is slid towards each bucket on the transport conveyor. At this time, since the contact portion 61 provided on the pushing member 59 is in contact with the rear side of the stack blank W ₃ , the pushing member 5
Even if 9 is driven at high speed, the stacking blank W ₃ is stored in the bucket 3 in a state where the collapse of the stacking blank W ₃ is prevented. Moreover, since the contact portion 61 of the pushing member 59 is in contact with the stacking blank W ₃ even when the stacking blank W ₃ is stored in the bucket 3, the stacking state of the stacking blank W ₃ in the bucket 3 is maintained. You can get organized quickly. Further, the integrated blank W on each holding block 40
₃ is transferred to the guide roller 57 of the transfer path 56, and at the same time, between the transfer path 56 and each bucket 3, and
The support rollers 68 and 69 project from the notches 18 and 19 of each bucket 3 to above the pedestal 13. Then, the stacking blank W ₃ is pushed into the bucket 3 by the pushing member 59.
And the supporting rollers 68, 69
Goes down. As a result, when the stacking blank W ₃ is loaded by the pushing member 59, the stacking blank W ₃ is spaced above the pedestal 13 of the bucket 3 with a space.
When the stacking blank W ₃ is prevented from being damaged due to contact with the stacking blank W ₃ and the stacking blank W ₃ is reliably stored in the bucket, the stacking blank W ₃ is lowered by the support rollers 68 and 69, so that the stacking blank W ₃ is pedestal 13 of the bucket 3. Land on the upper surface of.

When the stacking blank W ₃ is arranged in the bucket 3, the pushing member 59 retracts, and at the same time, the holding block 40 rises to support the support plate 20.
Together with supporting the integrated blank W ₃ .

As described above, the cutting device 1 performs the work of receiving the integrated blank W ₃ from the supporting plate 20 and then charging the integrated blank W ₃ into the bucket 3 by the pushing member 59. The support plate 2
The processing speed of the cutting device can be maintained by performing it while the blank W is being sent to the upper position.

Thereafter, the buckets 3 into which the stacking blanks W ₃ have been placed are released from their stopped states and are transported along the transport conveyor 2.

[0055]

As is apparent from the above, the present invention forms a plurality of integrated works by stacking works continuously sent from the cutting device on each support means.
Since the arranging means regulates the left and right sides and the front and rear sides of the stacking works with respect to the work delivery direction of the cutting means, the works supported on the supporting means can be stacked while being arranged.

Then, when transferring each accumulated work to each holding means that can be raised and lowered, each supporting means can be retracted, and each holding means can be lowered without contacting each supporting means with each accumulated work. Then, after each holding means receives the accumulated works and descends, the supporting means can be immediately advanced to support the works sent from the cutting means. Thus, even after each holding means is lowered, the work can be delivered from the cutting device, so that the cutting device can operate at high speed without interrupting the work forming process of the cutting device. The processing state can be maintained.

Further, since the accumulated works are kept in order in the descending position of each holding means and are thrown toward each bucket on the conveyor by the feeding means,
Even when driven at a high speed, it is possible to prevent the stacked work pieces from collapsing, and it is possible to quickly store each stacked work piece in an organized state in each bucket.

When a plurality of buckets are arranged on the transfer conveyor at a predetermined interval, each holding means is opened by the spacing means. This allows the spacing between the holding means to be quickly matched to the spacing between the buckets on the conveyor.

Therefore, according to the present invention, it is possible to provide an integrated work loading device capable of reliably maintaining the orderly stacked condition of plate-shaped integrated works and loading them into the bucket at high speed.
