In addition, a plurality of openings H are formed on the bottom surface of the tray T in accordance with the pin pitch described later. Furthermore, since the illustrated tray T places two bags P in parallel along the direction in which the chain 4 extends, its entire length L is extended.
[0009]
Reference numeral 5 is a pedestal provided below the chain 4 along the extending direction of the chain 4. The pedestal 5 can be moved up and down. On the pedestal 5, a pin loader 6 is provided below the roller 1. And the other end side of the roller 1 (that is, the downstream side of the chain 4) are supported so as to freely reciprocate along the extending direction of the chain 4. Further, a plurality of pins 7 having a round bar shape are provided upright on the upper surface of the pin loader 6. Further, the tip of the pin 7 has a hemispherical shape so that the bag P is prevented from being damaged by the tip of the pin 7 when the bag P is supported from below by the tip of the pin 7 as will be described later. .
[0010]
Here, as shown in FIG. 2, the pitch of the pins 7 (symbol A in the figure) is the same as the pitch of the openings H formed on the bottom surface of the tray T. The pitch of the pins 7 along the direction perpendicular to the extending direction is adjusted so that the pins 7 are positioned between the adjacent rollers 1. The length of the pin 7 is such that the tip of the pin 7 is positioned below the tray T when the pedestal 5 is lowered, and the tip of the pin 7 protrudes above the roller 1 when the pedestal 5 is raised. It is adjusted to do. Accordingly, when the pin loader 6 is disposed below the roller 1 and the pedestal 5 is raised, the tip of the pin 7 is inserted into the opening H from below, passes through the tray T, and passes between adjacent rollers 1. Projects upward from the roller 1.
[0011]
Next, a method for transferring the bag body P from the roller 1 onto the tray T by the transfer device having the above configuration will be described below with reference to FIGS.
[0012]
In FIG. 3, the pedestal 5 is in a lowered state, and the pin loader 6 is disposed below the roller 1. When the bag body P is transported onto the roller 1 and the mounting portion of the bag body P located on the downstream side of the chain 4 in the tray T reaches below the roller 1, the rotation of the roller 1 and the tray by the chain 4 The conveyance of T is stopped.
[0013]
Next, when the pedestal 5 is raised, as shown in FIG. 4, the tip of the pin 7 is inserted into the opening H from below and passes through the tray T. Further, as shown in FIG. And protrudes upward from the roller 1. Then, the bag body P is supported from below by the tip of the pin 7 and lifted above the roller 1.
[0014]
When the tray T and the pin loader 6 are moved to the other end side of the roller 1 in this state, the pin 7 passes between adjacent rollers 1 while supporting the bag body P, and the other end of the roller 1 is moved. Move to the side. As shown in FIG. 6, when the pin 7 has completely moved to the outside of the other end of the roller 1 (the placement portion of the bag body P located on the upstream side of the chain 4 in the tray T reaches below the roller 1. Then, the pedestal 5 is lowered and the pins 7 are pulled out below the tray T. As a result, as shown in FIG. 7, the bag body P is placed on the placement portion of the bag body P located on the downstream side of the chain 4 on the tray T. Transferred onto T.
[0015]
Thereafter, as shown in FIG. 8, only the pin loader 6 is moved below the roller 1, and the above operation is performed on the new bag body P conveyed on the roller 1, so that the chain 4 of the tray T The bag body P is also placed on the placement site of the bag body P located on the upstream side, and the transfer of the bag body P from the roller 1 onto the tray T is completed. The bag P placed on the tray T is transported further down the rail 4 to the next process.
[0016]
According to the above method, it is possible to easily transfer the bag body P such as a retort pouch, which has been difficult to be transferred by suction, from the roller 1 onto the tray T regardless of its weight or contents. It has become. Further, since the bag body P is supported from below by the plurality of pins 7, the weight of the bag body P is dispersed to the plurality of pins 7, and the tip of the pin 7 has a hemispherical shape. When the bag body P is supported by the above, the bag body P is not damaged by the tip of the pin 7.
[0017]
On the other hand, when the bag body P is transferred from the tray T onto the roller 1, the steps shown in FIGS. 3 to 7 may be performed in reverse.
[0018]
In the above embodiment, since two bags P are placed in parallel on the tray T, the position of the tray T is changed when the bag P is placed on one tray, and the above-described FIGS. Although the operation shown in FIG. 8 is performed twice, it is also possible to place three or more bags P on the tray T by performing the above operation three times or more by changing the position of the tray T. On the other hand, when only one bag body P is placed on one tray T, it goes without saying that the above-described operation is performed only once for each tray T. The operation / deactivation of the roller 1, the chain 4, the pedestal 5, and the pin loader 6 can be automatically controlled by using a program control or a known control device such as a photo sensor or a contact sensor.
