Description

[Detailed Description of the Invention] Purpose of the Invention [Industrial field of application] The invention is, for example, that a film lid is adhered by heat-sealing treatment to a four-sided flange formed on the outer periphery of the upper end of a container such as tofu. The present invention relates to a device for supplying the container by a feeding member movably provided by a driving means with respect to a sealing mechanism that closes an opening inside the flange.

[Prior Art] Conventionally, as a pasting machine of this type, for example, Japanese Patent Laid-Open No. 1-153406
There is one shown in the publication. In the same sticking machine, the strip-shaped film is placed on the four side flanges of the container conveyed on the seal stand, and the four side flanges and the strip-shaped film are sandwiched by the lower mold and the heat-seal upper mold to form the four-sided film. It is attached on the flange, the attached film lid is pulled out from the band-shaped film according to the outline of the flange on the four sides, the upper and lower molds are separated from the container with the film lid, and the container is taken out from the seal table. ing.

The container is pushed by a feed rod on the feed table and is conveyed on the seal table along both guide rods.

[Problems to be Solved by the Invention] In this sticking machine, the side surface of the container placed on the feeding table is pushed by the feeding rod, and the bottom surface of the container slides on the feeding table to convey the container. Therefore, the frictional force between the bottom surface of the container and the feeding table becomes large, and the container is less likely to slip on the feeding table. In particular, when the height of the container is high, the side surface of the container may be pushed by the feed rod to tilt the container in the conveying direction, and water or the like in the container may flow out.

Further, since the transport speed of the container on the feeding table is constant, increasing the transport speed of the sticking machine makes it easier for water and the like in the container to flow out, thus limiting the transport speed.

An object of the present invention is to improve the container so that it can be stably transported and prevent water and the like from flowing out of the container.

Another object of the present invention is to prevent the outflow of water and the like in the container by dividing the conveying speed into two stages and to improve the conveying efficiency.

A film lid sticking machine in which the container is fed by a feeding member movably provided by a driving means to a sealing mechanism that sticks a lid by a heat sealing process and closes an opening inside the flange. In the container supply device in, in the lower part of the supply path of the strip-shaped film from which the film lid is extracted, opposing mounting members provided along the supply path,
Of the four side flanges, a container guide groove provided between the two mounting members so that the two opposite side flanges can be placed and supported on the mounting member, and so as to pass through the guide groove.
A first feeding member provided movably across the container carry-in side and the container carry-out side, and similarly, so as to pass through the guide groove, can be moved at a faster carrying speed on the container carry-out side than the first sending member. A second feeding member provided, and the sealing mechanism is arranged at the container unloading position by the second feeding member, and the container conveyed by the first feeding member reaches a position below the film supply path of the strip-shaped film. After that, the driving means is set so that the second feeding member overtakes the first feeding member.

Rotating shafts 11 and 12 are provided on both front and rear sides between the left and right machine frames 10, and both front and rear end portions of a movable member 13 are screwed onto both left and right sides of the front and rear rotating shafts 11 and 12. A mounting plate 14 is attached to the left and right movable members 13, and an inner edge 14 of the left and right mounting plates 14 is attached.
A guide groove 15 extending in the front-rear direction is formed between a.
Then, when both the front and rear rotary shafts 11 and 12 rotate, the left and right movable members 13 move in the left and right directions along the coaxial axes 11 and 12, and the left and right mounting plates 14 approach and separate from each other so that the inner edges 14a thereof are separated from each other. The interval can be changed.

A first chain 16 is supported between the front and rear ends of both the left and right machine frames 10 on the container loading side and the container unloading side, and a plurality of first feed rods 17 are installed between the left and right first chain 16 respectively. There is. A second chain is provided at the rear ends of the left and right machine frames 10 on the container unloading side near the left and right mounting plates 9 of the first sealing mechanism 7.

The left and right flanges 4 of the container 2 are placed on the left and right placing plates 9 of the first sealing mechanism 7 at a speed higher than that of the case.

In particular, in this embodiment, since the left and right flanges 4 of the container 2 having a smaller area than the bottom surface of the container 2 slide on the left and right mounting plates 14 to convey the container 2, The frictional force between the left and right flanges 4 of the container 2 and the mounting plate 14 is reduced, and the slip between them is improved. Therefore, the force with which the container 2 is pushed by the feed rods 17 and 19 is reliably transmitted as the moving force of the container 2, and the container 2 is less likely to be tilted in the carrying direction, and the container 2 can be carried with good stability.
Water inside will not flow out easily.

Moreover, the change in the width between the left and right flanges 4 of the container 2 is adjusted by adjusting the distance between the left and right mounting plates 14, and the change in the width between the front and rear flanges 3 of the container 2 is changed by the longitudinal direction of the guide groove 15. Since the change in height can be allowed depending on the depth of the guide groove 15, the containers 2 of various sizes can be easily transported.

Further, since the first feed rod 17 and the second feed rod 19 are divided, and the carry-out speed of the second feed rod 19 on the carry-out side is made higher than the transport speed of the first feed rod 17, the first feed rod having a slow carry-out speed. Water can be prevented from flowing out of the container 2 during transportation by 17, and
The second feed rod 19 having a high carrying speed can improve the carrying efficiency.

Further, since the moving paths of the first and second feeding rods 17 and 19 and the feeding path of the strip-shaped film 8 can be arranged vertically with the placing plate 14 as a boundary, the entire apparatus can be made compact. .

In addition, when the container 2 is conveyed by the second feed rod 19 having a high conveying speed, the opening 6 of the container 2 is covered with the belt-shaped film 8, so that water or the like may flow out from the container 2. Can be made smaller.
