Abstract

PURPOSE:To prevent cans from overlying on one another by sending out cans on a mount sheet at a speed lower than a carrying speed of the cans by a carrying means, moving a can pressing means together with a send-out means and pressing the pressing means intensively on a rear part in a sending direction. CONSTITUTION:A carriage 42 is attached to a running rail 41 extending from a mount sheet 2 side to a conveyer 3 side so that the carriage 42 can travel thereon, a push-out member 43 is provided on a rear end of the carriage 42 in a direction of sending out cans, and the carriage 42 is run at a slower speed than a carry speed of cans by the conveyer 3. Cylinders 51, 52 are provided on front and rear parts of the carriage 42, while chains 55, 56 are attached to their rods 53, 54, which hold a pressing board 57 for pressing the cans 1. The front chain 53 is shorter than the chain 54, so that pressing force of the pressing board 57 is stronger on the rear side. Therefore push-out force from the rear by the push-out member 43 becomes stronger as coming to the rear end, and the pressing force is also the stronger in the rear part so that the cans 1 will not overlie on one another.

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a can delivery device that sends out cans placed in an aligned state on a placement sheet from the placement sheet to a conveying means such as a belt conveyor. It is related to.

[Prior art and its problems] Traditionally, canned foods have been sterilized by heating.

In recent years, in order to efficiently heat and sterilize cans that have been canned in this way, a mounting sheet (21) with openings between the crosspieces (21) in a lattice shape is used, as shown in Fig. 6.
2), the cans (1) are placed on the crosspiece (21) of this placement sheet (2) in the required row as shown in FIG. Several stacking sheets (2) on which the cans (1) canned in this manner are placed in the required rows are stacked, and in this state, each placing sheet (2) is stacked.
The cans (1) placed on top are now heat sterilized all at once.

After the cans (1) placed on each placement sheet (2) are sterilized in this way, they are lined up on each placement sheet (2) as shown in Figure 8. Each can placed in (
1) from above the placement sheet (2) to a conveying means (3) such as a slat band conveyor, and the can (1) thus sent out is conveyed to the next process by this conveying means (3). I was doing it.

Here, in order to send the cans (1) arranged and placed on the placement sheet (2) as described above to the conveyance means (3) such as a slat band conveyor, conventionally As shown in FIG.
At the same time, an extrusion member (43) is provided at the rear end of the trolley (42) in the can feeding direction, and the trolley (42) is moved along the running rail (41) to the loading sheet (2) side. The can (1) placed on the placement sheet (2) is moved to the conveying means (3) side by the push-out member (43) provided on the trolley (42), and the can (1) placed on the placement sheet (2) is transferred to a slat band conveyor or the like. It was arranged to send it to the conveying means (3).

However, the can (1) placed on the placement sheet (2) in this way is transferred to a conveying means (3) such as a slat band conveyor.
), the relationship between the speed at which the extrusion member (43) sends out the can (1) to the conveying means (3) and the speed at which the can (1) is conveyed by the conveying means (3) does not go well. The cans (1) may fall over, and depending on the type of cans (), the cans (1) placed on the placement sheet (2) may remain aligned when the conveyance means (
3), which caused problems such as not being sent out and subsequent processing becoming troublesome.

For example, in recent years, inverted truncated conical cans (1) have been used to store water yokan, pudding, etc.; When the can <1) is placed face down and in the form of a truncated cone on the mounting sheet (2), the cart (42) is moved along the traveling rail (41) as described above.
2) side to the conveyance means (3) side, and this trolley (4)
2), the truncated conical can (1) placed on the placement sheet (2) is sent out to the conveyance means (3) such as a slat band conveyor. , as shown in Figure 9, the can (
1) gets on top of the previous can (1) and turns over, and when leading to the next process, the overturned can (1) must be returned to its original position, making subsequent processing very troublesome. There were other problems.

[Problems to be Solved by the Invention] This invention solves the above-mentioned problems when cans placed in an aligned state on a placement sheet are sent from the placement sheet to a conveyance means such as a slat band conveyor. The goal is to solve the following problems.

That is, in the present invention, when the cans arranged and placed on the placement sheet as described above are sent from the placement sheet to a conveying means such as a slat band conveyor, what kind of cans are used? The object of the present invention is to make it possible to reliably send the items to a conveying means in a state in which they are aligned even if there are any items.

[Means for Solving the Problems] In this invention, in order to solve the above-mentioned problems, the cans (1) placed in an array on the placement sheet (2) are transferred to the conveying means (3). ), the can delivery device moves from the placement sheet (2) side to the transportation device (3) side at a speed slower than the transportation speed of the cans 1) by the transportation device (3), ) The above can placed on <
1) to the conveying means (3), and together with the sending means (4), the can (1) placed on the placement sheet (2) is pressed down from above. and a presser means (5) that moves toward the conveyor means (3), and the force of the presser means (5) to press the can (1) is biased toward the rear side in the feeding direction of the can (1). That's what I did.

[Operation] In the can take-out device according to the present invention configured in this manner, the cans (1) placed in an aligned state on the placement sheet (2) are held by the holding means (5). (1

Then, the lifting device (22) moves the support to the platform (
23) Raise the next placed sheet (2) placed above, so that the upper surface of this placed sheet (2) is almost flush with the conveying side slat band surface of the slat band conveyor (3). I made it so.

After that, the can (1) placed on this placement sheet (2)
) are sent onto the slat band conveyor (3) in the same manner as in the previous case, and the cans (1
) was conveyed by this slat band conveyor (3).

[Effects of the Invention] As described in detail above, in the can feed comparison device according to the present invention, when sending the cans placed in an aligned state on the placement sheet to the conveyance means, the cans placed on the placement sheet are While holding down the cans placed on the holding sheet, the holding means is moved together with the feeding means from the placing sheet side to the conveying means side, and the multiple cans placed on the placing sheet are moved. It was arranged to send it out to the conveyance means by the sending means.

For this reason, the multi-cans placed on the placement sheet are sent out to the conveying means by the sending out means while being held down and aligned by the holding down means.

In addition, when holding down multiple cans placed on the placement sheet using the holding means, the force of holding down the cans by the holding means is biased toward the rear side in the feeding direction of the cans. Even when an inverted truncated cone-shaped can containing a truncated cone is placed face down in a truncated conical state on a placement sheet and sent from the placement sheet to the conveyance means by the above-mentioned feeding means, the conventional As a result, the later cans no longer ride on the earlier cans, causing the later cans to flip over.

Furthermore, in the can delivery device according to the present invention, when the delivery means sends out the multiple cans placed on the placement sheet to the conveyance means, the can delivery speed is set to the can conveyance speed by the conveyance means. Since the speed is made slower, the cans sent to the conveying means by the sending means are immediately conveyed by the conveying means, and there is no longer a case where the cans sent out stay at the conveying means and the later cans run over the previous cans. .

As a result, using the can dispensing device according to the present invention,
When the cans placed on the placement sheet are sent out to the conveyance means in an aligned state, it is ensured that the cans are sent out to the conveyance means in an aligned state no matter what type of cans. In particular, when an inverted truncated cone-shaped can containing water canisters, pudding, etc. is placed face down on a truncated conical sheet and sent to a conveying means, it is difficult to use the conventional method. In addition, the cans do not turn over, and the trouble of returning the turned cans to their original position when leading them to the next process is eliminated, making it possible to transport the cans more efficiently.
