Abstract

PURPOSE:To reduce a working space and manhours in a stacking and taking off device for a paper container by carrying in a preset direction paper containers into a sleeve, the bottom of which is closed with an oscillating base, by using pneumatic pressure, stacking up the containers to a prescribed number, and oscillating the oscillating base, thereby opening the bottom of the sleeve in order to take the containers out. CONSTITUTION:A container 'a' is carried by pneumatic pressure in an air chute duct 29, interposed into a sleeve 7, which faces the duct 29, and supported by an oscillating base, which is situated at the bottom of the sleeve 7. Thus, the containers 'a', which are sent in in turn, are stacked up in the sleeve 7 to a prescribed number. Next, a laterally moving member 8 is actuated to laterally move the sleeves 7 and 7 along the shafts 3 and 3, so that an emptied sleeve 7 is brought in line with the duct 29, while a filled-up sleeve 7 is moved to the container-take-out position. Next, a boarding plate 12 is tilted forward by using an closing motion driving member 14, thereby opening the bottom end of the sleeve 7 in order to take the container 'a' out. With this contrivance, both space and manhour can be reduced.

The apparatus for polymerizing, accumulating and taking out lightweight containers made of paper or the like according to the present invention is constructed as described above, and the operation for polymerizing and accumulating lightweight containers will be explained in more detail below.

The explanation will now be made assuming that the sleeve 7.7 and the ejection mechanism 26 are in the state shown in FIG.

The paper container manufacturing apparatus is described in detail, for example, in the specification and drawings of Japanese Patent Application No. 114095/1983, previously filed by the present applicant.

That is, this device is a device for manufacturing a paper container having a bottom plate at the bottom of a cylindrical side plate, and includes a continuous paper conveying device that conveys a long continuous paper in its length direction, and a continuous paper conveying device that conveys a long continuous paper in its length direction. a perforation forming body that forms a plurality of perforation-like cutting lines in the width direction; a first gluing machine that applies glue to one side in the length direction of the continuous paper; a second gluing machine that applies glue along the perforated cutting line; a cutter that cuts the portion that will become the side plate divided by the perforated cutting line from the perforated cutting line; A presser for pressing the cut side plate pieces onto the peripheral surface of the wrap-around core to which the bottom plate has been adsorbed among a plurality of wrap-around cores protruding around the core rotating body, and a presser for pressing the cut side plate pieces around the wrap-around core. a wrapping forming mechanism for wrapping; a heating pressing body that heats and presses the overlapping portion of the side plate piece wound around the wrapping forming core by the wrapping forming mechanism and adheres the overlapping portion with glue applied to the overlapping portion; A bottom plate supply mechanism that previously supplies the bottom plate to the end face of the wrapped or shaped core, and a cylindrical side plate whose overlapping portion is bonded to form a cylindrical shape by bending it along the outside of the bottom plate. The paper container manufacturing apparatus is characterized in that it is equipped with a bottom plate attaching mechanism for adhering and attaching the bottom plate to the end edge of the cylindrical side plate using the glue applied along the bent portion.

In the present invention, when the bottom plate is attached to the tapered cylindrical side plate having a large cylindrical shape in the above-mentioned apparatus, it is removed by being blown away by air pressure from the processing core.

Container a, which has been pressure-fed through the air chute duct 29 with one end located at this removal position, is transported through the air chute duct 29.
The other end of the sleeve 9 is inserted into the opposing right sleeve 7 as shown in FIG. Stay within.

Thereafter, similarly, the containers a that have been pressure-fed one after another are sequentially polymerized under air pressure through the state shown in FIG. 12.

At this time, a portion of the air leaks out of the sleeve through the hole 27 of the sleeve 7, so the air flow is smoothly conveyed without stopping, and the swinging of the swinging base 17 allows the air to be polymerized and accumulated in the sleeve 7 in an orderly manner. do.

That is, there are a certain number of pieces (for example, to pieces, 20 pieces) in the sleeve 7.
To accommodate and polymerize the containers a of 1), as shown in FIG. 10 to FIG.
When the shaft 15 is rotated through the chain 24 which is hung between the sprocket 22a1 of 3 and the sprocket 22b of the shaft 15, a spring is applied to the cam surface of the eccentric cam 2l attached to the shaft 15 through the roller 20. Since the lever 18 pressed by the lever 19 is always swinging about the shaft 11 as a fulcrum, the swing base 17 attached to the shaft 11 via the arm 16 moves up and down, as shown in FIG. In this way, the air between each container a is excluded to make the polymerization more dense.

Since this up-and-down swinging operation is always performed while a certain amount of containers a enter the sleeve 7, a predetermined number of lightweight containers can be piled up in an orderly manner.

When the stacking and accumulation of a certain number of containers a is completed, the lateral movement member 8 such as a fluid cylinder is activated.

This operation of the lateral movement member 8 moves the sleeve 7.7 into the holders 6, 6.
The back plate 5 mounted via the guide block 4.4 slides on the shafts 3, 3 and moves to the right as shown in FIGS. 6 and 8.

At this time, the lowest one of the containers a, a superimposed in the sleeve 7 moves from the swing base l7 onto the container mounting plate 12 which is located at a lower position than this and is in a horizontal state, This time, the container placement plate 12 prevents the container from falling off the sleeve 7.

When the positions of the sleeves 7, 7 have completely moved to the right as shown in FIGS. 6 and 8, the opening/closing drive member 14 such as a fluid cylinder is actuated and the lever l is in the state shown in FIG. 4.
3 upward and rotate the shaft 9, as shown in FIGS. 9 and 14, the container mounting plate 12. 12 is tilted forward and opened, and the containers a, a that have been assembled in the sleeve 7 can be dropped into the container storage box 33 from inside the sleeve 7 as shown in FIG. 15 and taken out.

When the sleeve 7 is moved to the right as described above, the upper end of the left sleeve 7, the lower end of the air chute duct 29, and the swing base 17 shown in FIG. a are sent one after another.

When a certain amount of containers enter this sleeve, the lateral movement member 8 such as a fluid cylinder and the opening/closing drive member 14 operate in the same manner as described above, and move the sleeves 7, 7, which have been moving to the right, to the left and move them forward. The open container mounting plate 12 is returned horizontally in advance.

Thereafter, a predetermined number of stacked containers can be taken out alternately from the left or right sleeve 7 by performing the same operations as described above.

Note that a well-known crank mechanism may be used instead of the eccentric cam 21 in the above embodiment, and in this case, the spring 1
9 can be omitted.

In addition, the lightweight containers carried in and falling from the upper part of the sleeve 77 are lightweight containers made by well-known means other than those related to the applicant's earlier application mentioned above, such as plastic film molded containers, cups with cardboard bottom plates, or hollow conical containers. This can be carried out using any tapered lightweight container such as a cone container.

And instead of carrying these containers into the sleeve 7 from the air chute duct 29 of the embodiment, they are dropped one by one with the bottoms facing one side through a well-known alignment device provided at the top of the sleeve 7. The lightweight containers a may be sequentially dropped into the sleeve from the upper part of the sleeve 7 and carried into the sleeve.

[Effects of the Invention] Since the present invention is configured as described above, it produces the effects described below.

In the device for collecting, collecting and taking out lightweight containers made of paper or the like according to claim 1, the stacking and stacking of manufactured lightweight containers such as paper and the taking out of containers for each predetermined number of containers can be done automatically without any manual effort, so first of all, it is hygienic. This makes it possible to reduce the work space and manufacturing costs, and has the advantage that lightweight containers such as paper containers can be continuously polymerized and taken out without interruption.

According to claim 2, a large empty space can be provided below the sleeve 7, facilitating coordination with the packaging process, improving workability, and smoothing the movement of the swing base 17. have an effect.

In the third aspect, since air is retained in the sleeve into which the lightweight containers are dropped by air transport, smooth transport, stacking, and removal can be achieved.
