Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention relates to an apparatus for automatically placing sliced bacon or the like on a mount.

《Prior art》 When packaging sliced bacon, ham, etc., firstly, logs of bacon, etc. are sliced thinly using a slicer, and then stacked in units of several to ten or more slices by shifting them little by little. The paper is then transported to a packaging machine for packaging.
However, products such as bacon and ham have a high oil content, and when sliced thinly, they lose their so-called firmness and have poor slipperiness. Therefore, in the past, when packaging these, they were stacked in a staggered manner and then placed on a thick mount to integrate them into one piece to improve handling.

《Problem that the invention aims to solve》 However, the work of placing the mount on the mount was also done manually, but now we are trying to do this automatically, and the mount is successively sliced thinly by a slicer and falls down. Attempts have been made to receive the bacon on a conveyor, shift it little by little, and transfer it in units of several to ten or more pieces in a stacked state, and then transfer it directly onto a mount that is conveyed separately, but the slicer Therefore, the falling position of bacon, ham, etc. that is successively sliced into thin pieces and falling onto the conveyor is not necessarily accurate, and the falling position and direction may vary slightly, so that the staggered and stacked items in units of several to ten or more pieces may remain as they are. If you move forward in the state of
Since the posture and center of transfer are different for each item, if these items are transferred as they are onto a mount that is transferred separately, the state in which the items are placed on the mount, that is, the placement position and orientation, will be uneven, resulting in a decrease in product value. It was hot.

The present invention was created in view of the above-mentioned problems, and its purpose is to sequentially slice the slices thinly using a slicer and transport them in units of several to ten or more slices in a slightly staggered stacked state. Correcting the conveying posture of the articles such as the sliced bacon to the correct orientation without changing their stacked form, and correcting the position of the separately conveyed mount to match the article to ensure that the article is placed at a predetermined position on the mount. We are trying to provide a device that can be placed on

It is placed thereon and further conveyed to a subsequent stage device (not shown) by the carry-out conveyor 22. In this case, the endless chains 4, 4 of the mount feeding device 2 are operated by the card pushing claws 3, 3 in response to a command from a micro switch combined with a timing cam 34.
When the mount 5 reaches the standby position, its movement is stopped.

<<Effect of the invention>> As described above, according to the invention, bacon blocks, etc., which are thinly sliced by a slicer and transported in a predetermined number of piles, may be slightly disturbed in position or in the transport posture. Even if the bacon blocks are sent on the conveyor in a disordered and uneven manner, the orientation is corrected at a predetermined position on the conveyor, the conveyor is corrected to the correct conveyance posture, and the bacon blocks are transferred. The position of the mount is adjusted to match the corrected conveyance center of the bacon block by a mount position correcting device at the position of the mount feeding device disposed below the transport conveyor, and then the mount is transported. . In addition, since the discharging end of the conveyor is arranged close to the mount feeding surface of the mount feeding device, the bacon blocks can always be reliably placed and taken out at a predetermined position on the mount. Moreover, since it does not require any manpower at all, it has the effect of allowing work to be carried out hygienically and with high efficiency.
