- a filling, sealing and sterilizing section is provided over a plurality of sections (Japanese Patent Application Laid-Open No. 2000-722). No. 16). Providing the filling, sealing and sterilization sections over multiple sections inevitably leads to an extension of the captain. It is an object of the present invention to provide a transfer competition for a latest high-speed liquid filling machine having a longer length. Endless chains such as endless chains in conveyors, the load on the endless chains on the conveyors where the elongation of some endless chains progresses faster than other endless chains is equalized, thereby reducing the endless chain life.
- An object of the present invention is to provide a conveyer for a rectangular container with a bottom that has a long life.
- Containers transported by this type of high-speed liquid filling machine have backling (rhombic deformation). Due to this buckling, different loads occur on the left and right endless chains of the chain conveyor.However, in the latest high-speed liquid filling machines, the length of the machine is longer, and the left and right endless chains are correspondingly longer. First, the load on the endless chain, especially on the side that applies the pushing force while holding the container at an acute angle, increased, and the difference in the extension of the left and right endless chains became more remarkable than expected. In addition, even with the high-speed operation of the filling machine (high-speed operation of the chain conveyor), the load on each endless chain, especially the endless chain on the side that applies the force that pushes forward while holding the acute angle of the container, increases. It has been found that the difference in the extension of the left and right endless chains becomes more remarkable than expected, and that one-sided extension of the endless chain appears.
- the container holder 24 provided on the bottomed rectangular cylindrical container transport conveyor is composed of four holding pieces 24a, 24b, 24c and 24d.
- the bottomed rectangular cylindrical container is not square or rectangular in cross section as its initial shape, if it is square or rectangular in cross section, the bottomed rectangular cylindrical container P is transported in the direction of arrow X.
- the holding pieces 2 4 b and 24 d located behind the bottomed rectangular cylindrical container hold the bottomed rectangular cylindrical container and push it forward, so the holding pieces 24 b and 24 d
- the same load is applied to the endless chain 15 R and the endless chain 15 L to which is attached, but if the cross section of the bottomed rectangular cylindrical container P is deformed into a rhombus or parallelogram, , Having The holding piece 24 d corresponding to the obtuse angle at the rear of the bottom rectangular cylindrical container P does not contribute to the extrusion of the bottomed rectangular cylindrical container P, and only the holding piece 24 b corresponding to the acute rear angle is the bottomed rectangular cylindrical container. Involved in the extrusion of P.
- the container holder 24 is formed of two holding pieces 24 b and 24 c that hold the acute corners and two corners of the bottomed rectangular cylindrical container P whose cross section is deformed into a rhombus or a parallelogram. In this case, as in the case of four holding pieces, the endless chain 15 R to which the holding pieces 24 b are attached is loaded with a larger load than the endless chain 15 L. Large elongation occurs.
- the one-sided extension of the endless chain is also generated by the force of the endless chain correcting the buckling of the bottomed rectangular cylindrical container P (buckling correction force). That is, when the bottomed rectangular cylindrical container P is transported in the direction of arrow X, the load applied to the endless chain 15R that holds the acute-angled corner at the rear of the bottomed rectangular cylindrical container in the traveling direction is an endless chain. This is the load that is the sum of the one tension and the backing correction force (acting in the transport direction). On the other hand, when the container is transported in the direction of the arrow X, the load applied to the endless chain 15 L is the load that is the difference between the tension of the endless chain and the buckling correction force (acting in the opposite direction to the transport direction). is there. For this reason, the load applied to the endless chain 15R is greater than that of the endless chain 15L, and the endless chain is partially stretched. This tendency becomes more remarkable as the buckling of the bottomed rectangular cylindrical container P becomes stronger.

- the endless chain 15R includes two endless chains 15a and 15b, and the front holding piece 24a and the rear holding are provided.
- the figure shows the piece 24b attached to the endless chains 15a, 15b.
- the rear corner of the bottomed rectangular cylindrical container P is kept at an acute angle. Since a larger load is applied to the endless chain 15 R to which the holding pieces 24 b attached to the endless chain 15 R than to the endless chain 15 L, the two corners at the rear in the traveling direction of the bottomed rectangular cylindrical container are placed at The bottomed rectangular cylindrical container is transported while being held by the holder. This makes it possible to equalize the load applied to the left and right endless chains.
- Fig. 4 shows an example of a container transport conveyor equipped with such an upper and lower four-stage endless chain.
- Fig. 4 is a side view showing the endless chain 15R on the right side in the traveling direction.
- the endless chain 15R has four endless chains 15a, 15b, 15c and 15d.
- the figure shows the rear holding piece 24b attached to the endless chains 15a and 15c, and the front holding piece 24a attached to the endless chains 15b and 15d.
- the endless chains 15 a and 15 to which the holding pieces 24 b holding the corners at the rear in the traveling direction of the bottomed rectangular cylindrical container P are attached Since a large load is applied to c, the bottomed rectangular cylindrical container is transported in a state where the container holder holds both rear corners in the traveling direction of the bottomed rectangular cylindrical container. This makes it possible to equalize the load applied to the left and right endless chains.
- Figures 5 to 7 show that the control means 28 independently controls the timing and rotation speed of the servo motor 27, and shows the operation curves of the obtuse angle side chain (15L) and the acute angle side chain (15R). Shows the container holding state by the container holder (left; at the start of transport, middle; during transport, right; at the end of transport).
- the obtuse angle chain (15L) moves first, and the holding piece 24d attached to the obtuse angle chain moves the rear angle of the rectangular cylindrical container.
- the obtuse angle side chain (15L) and the acute angle side chain (15R) start moving at the same time, but immediately after the start of movement, the obtuse angle
- the moving speed of the side chain (15L) is relatively fast, and the holding piece 24d attached to the obtuse side chain (15L) immediately contacts the rear corner of the rectangular cylindrical container,
- the holding piece 24 d of the obtuse side chain (15 L) and the holding piece 24 b of the acute angle side chain (15 R) both hold the rear corners of the rectangular cylindrical container.
- the moving speed of the acute side chain (15R) becomes relatively high before the transfer is completed, and the obtuse side chain (15L) and the acute side chain (15R) Stops and the transfer ends. Also, the deviation (distance) between the left and right holding pieces in a pair of endless chains is set to be within 5 mm at most, regardless of the size of the container.
- the obtuse angle side chain (15L) moves first, and the holding piece 24d attached to the obtuse angle side chain has a rectangular cylindrical shape. Conveyance starts when the rear corner of the container comes into contact, that is, when both rear corners of the rectangular cylindrical container are held by the holding pieces 24b and 24d, and is conveyed in this state. , First blunt The angle side chain (15L) stops, then the acute angle side chain (15R) stops, and the transfer ends.
- the holding piece 24 d attached to the obtuse angle side chain (15 L) is in a state of being advanced more than the acute angle side holding piece 24, but the left and right holding pieces (24 d, 24 b) are displaced. (Distance) is set to be within 5mm at the maximum.
- the operation curves of the obtuse side chain (15 L) and the acute side chain (15 R) are not particularly limited. However, the operation curves of the acute side chain and the obtuse side chain are the same, and only the phase of the acute side chain is obtuse. It is preferable to make the delay behind the side chain because control is easy.
- the milk pack is transported using the container transport conveyor device of a high-speed liquid filling machine (UPN-SE 160.0; manufactured by Shikoku Kakoki Co., Ltd.), and the endless chain moves due to the difference in the endless chain movement. I checked whether the torque was equalized. Specifically, when the obtuse side chain and the acute side chain are operated at the same moving speed (control), as shown in Fig. 7, the phase of the operation curve of the acute side chain is lower than that of the obtuse side chain. The torque applied to the obtuse side chain and the acute side chain was measured for each of 3 ° and 4 °.
- UPN-SE 160.0 manufactured by Shikoku Kakoki Co., Ltd.
- the displacement (distance) of the holding pieces attached to the obtuse angle side chain and the acute angle side chain was about 2-3 mm at the maximum, respectively.
- the transfer conditions and measurement results are shown below.
- the torque value was expressed as a relative value when the rated torque of the servomotor was 100%. This value is considered to be proportional to the tension of the endless chain.
- Conveyed object 100 ml milk pack (70 mm square force 1 ton)
- Peak torque Obtuse angle 55 to 57% Acute angle: 75 to 77% Effective torque Obtuse angle: 17% Acute angle: 29 to 30%
- Peak torque Obtuse angle 69% Acute angle: 68%
- Effective torque Obtuse angle side 23% Acute angle side: 30%
- Peak torque Obtuse side 69% Acute side: 63%
