Abstract

PROBLEM TO BE SOLVED: To stabilize bagging operation of sandwiches or the like and fully automate a product production process by providing a loading mechanism having a tray transfer means which transfers a tray on which the sandwiches or the like can be mounted into a packaging bag which has already opened and a position adjust mechanism which can transfer the sandwiches or the like on a conveyer onto the tray. SOLUTION: A detection means 7 senses that a sandwich S or the like has been transferred to a tray 2a of a loading mechanism 2 by a conveyer 1. A position adjust mechanism 3 advances a back-pushing part 3a with a signal from the detection means 7 for pushing the sandwich S or the like until its tip is aligned with a tip of the tray 2a and transferring it from the conveyer 1 onto the tray 2a. Subsequently, the loading mechanism 2 is driven to advance a tray transfer means 2b for casing the sandwich S or the like together with the tray 2a into a packaging bag by an opening mechanism 5. Then the tray transfer means 2b is further advanced to a package posture changing mechanism 6, and the bagged packaging bag is cut off from a packaging bag supply mechanism 4 to be received into a bucket 6a.

[0009]

Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an entire bag packing apparatus according to an embodiment of the present invention, and is mainly a conveyor 1 for transporting a sandwich or the like S at a constant speed.
And a loading mechanism 2 for packing the sandwich S or the like in a packaging bag
And a position adjusting mechanism 3 for replacing the sandwich S or the like on the conveyor 1 with the loading mechanism 2. In the drawing, reference numeral 4 denotes a packaging bag supply mechanism for supplying a large number of stacked packaging bags one by one to the apparatus in order from the top, and 5 denotes an opening for opening only the uppermost packaging bag of the packaging bag supply mechanism 4. A mechanism 6 is a package attitude changing mechanism for feeding the sandwich S or the like, which has been packed in the bag, into the sealing device.

The conveyor 1 is formed of, for example, a belt conveyor, and transports the sandwich S or the like to the loading mechanism 2 with the inclined surface of the sandwich S having a right-angled triangular shape as a traveling direction. This conveyor 1 can be manually sandwiched S or the like.
Is placed at an arbitrary position. In the figure, 1a is a conveyor 1.
Side plates provided on both sides of the conveyor, the sandwich S and the like are prevented from overturning, and the sandwich S or the like manually placed on the conveyor 1 is directed straight forward by sandwiching the sandwich S between the side plates 1a, thereby ensuring the loading mechanism 2 Also has an alignment function for changing the tray 2a.

The loading mechanism 2 has a tray 2a on which a sandwich S or the like is placed, and is connected to the tray 2a.
a is transferred to the inside of a packaging bag opened on the front packaging bag supply mechanism 4 to pack the sandwich S or the like, and further the tray S is transferred to the bucket 6a of the package attitude change mechanism 6 for the packed sandwich S or the like. 2b. In the tray 2a, side plates 2d are set up on both sides of the table 2c in order to place the sandwich S or the like without breaking the shape. The tray transfer means 2b is formed of, for example, an air cylinder, but may be driven by a motor.

The position adjusting mechanism 3 includes a push-up portion 3a which can be brought into contact with the vertical portion of the sandwich S or the like, and a lifting / lowering means which is connected to the push-up portion 3a and lowers the push-down portion 3a behind the vertical surface of the sandwich S or the like. 3b, and advancing / retreating means 3c which pushes down the further pushing portion 3a forward and replaces the sandwich S or the like S on the conveyor 1 with the tray 2a of the loading mechanism 2. That is, S such as a sandwich is conveyor 1
Is placed on the tray 2a to some extent due to the momentum, but since this is incomplete, the pusher 3a is pushed by the advance / retreat means 3c.
Is moved forward to completely replace the sandwich S or the like on the tray 2a. The lifting / lowering means 3b and the reciprocating means 3c are configured using an air cylinder or a motor as a drive source, similarly to the tray transfer means 2b.

When the sandwich or the like S is replaced on the tray 2a, it is preferable that the tip of the sandwich or the like S coincides with the tip of the tray 2a. This is because even if the objects to be bagged change and their sizes differ,
This is because the bag can always be accurately packed based on the tip of the tray 2a. For this reason, the tray 2a is formed from a material in which the packaging bag is slippery.

The operation of the bag packing apparatus having the above configuration will be described. First, a sandwich S or the like is placed on the conveyor 1 manually. In this case, the sandwich or the like S is placed so that the longest slope thereof faces forward. Next, the detecting means 7 such as an optical sensor detects that the sandwich S or the like is conveyed to the tray 2a of the loading mechanism 2 by the conveyor 1, and the position adjusting mechanism 3 is driven. That is, the detecting means 7
The pusher 3a is lowered by the raising / lowering means 3b in response to the signal from the controller 3, and further the pusher 3a is advanced by the advance / retreat means 3c to push the sandwich S or the like to a position where the tip of the sandwich S coincides with the tip of the tray 2a. Tray 2a
Replace the sandwich S etc.

Subsequently, the transfer to the tray 2a is completed,
That is, a detection unit is provided after a predetermined time from the forward operation of the advance / retreat unit 3c or at the tip of the tray 2a, and the loading mechanism 2 is driven in response to a signal from the detection unit. The packaging bag is opened by the opening mechanism 5 at least before the loading mechanism 2 is driven. And the tray transfer means 2b
, The sandwich S or the like is packed in the packaging bag together with the tray 2a, and the tray transfer means 2b is further advanced to the package posture changing mechanism 6, to separate the packed packaging bag from the packaging bag supply mechanism 4, and The packed bag is accommodated in the bucket 6 a of the package posture changing mechanism 6.

At this time, when the tray 2a is molded from a slippery material as described above, only the tray 2a precedes the bag filling step by the loading mechanism 2, and depending on the potential energy of the sandwich S or the like, the tray 2a may be placed on the tray 2a. The position may deviate from the transfer position. Therefore, in order to avoid such inconvenience, it is necessary to adjust the forward speed of the tray transfer means 2b.

However, as described above, the tray transfer means 2b
In this embodiment, the following means was used because suppressing the forward speed of the vehicle affects production efficiency. That is, in addition to the advancing / retreating means 3c, the position adjusting mechanism 3 is provided with an extruding means 3d capable of advancing the pusher 3a, and the extruding means 3d is synchronized with the tray transfer means 2b of the loading mechanism 2 in the bag filling step. The package is advanced at a speed, and the pusher 3a is brought into contact with the vertical portion of the sandwich S or the like until the package is stored in the bucket 6a. By this means,
Bags can be packed while holding the sandwich S or the like at the replacement position.

When the bag filling is completed as described above, the tray transfer means 2b retracts the tray 2a to the original position, and at the same time, moves the position adjusting mechanism 3 by retreating the pushing means 3d and the reciprocating means 3c and raising the elevating means 3b. Return to the original position,
It goes without saying that it is ready for the next bagging process.

In the above-described embodiment, the description has been given of the case where the bagged package is finally transferred to the bucket of the package attitude changing mechanism 6 by the loading mechanism 2. However, in the present invention, the tray transfer means of the loading mechanism 2 is used. 2b and position adjustment mechanism 3
The operation range of the push-out means 3d is limited to the packaging bag, and at least the packing is completed.
The transfer to the container may use another means.

[0020]

As described above, according to the present invention, the manual work only requires placing the sandwich or the like on the conveyor,
This work does not require any experience or skill, and it completely eliminates the individual differences that have an adverse effect on the production efficiency. After the above work, the sandwich etc. can be automatically bagged. Was fully automated. Moreover, as long as the inclined surface of the sandwich or the like faces forward on the conveyor, it can be placed at an arbitrary position, so that the placing operation is simple.
