Description

[Detailed Description of the Invention] This invention is based on the invention, in which a large number of disc-shaped articles of the same shape, such as can lids, bottle lint, etc., are piled up in rows to form a cylindrical shape. Automatically cuts open a package covered with O packaging material such as or resin-coated paper and removes the packaging material.
This invention relates to a packaging material incision and removal device that automatically removes contents.

Conventionally, since the cutting device and the removing device for this type of Dvc package were separated, a device was required to transport the unstable package cut open by the cutting device to the removing device. During this transfer, the lid fell down due to the folding opening of the package, and
Not only was it inefficient because the production process had to be interrupted, but it also caused the equipment to malfunction. In addition, in order to increase the processing capacity and process long packages, the f2 size becomes large, which causes high costs. O To solve the problem [.

An incision and removal device is constructed by integrating a package cutting device and a removal device, and an O-transfer device with a speed increasing mechanism for transferring a cylindrical package is connected to one end of the device. The present invention provides a packaging material cutting and removal device for a cylindrical package, which includes a content discharge device adjacent to the content discharge device for automatically discharging the removed content.

The invention will be described in detail below with reference to the drawings.

In the pre-process, first, a large number of disk-shaped articles of the same shape, such as can lids and pin lids, are piled up in rows to form a cylindrical shape. A package 1 covered with a packaging material such as the following is automatically produced and transported to a customer. In order to peek into the contents of the package,
The package is transferred to the transfer device 12 by any suitable method.

The transfer device f2Vi has two O-pulleys 3 and 3' with a rubber hook passed between them, and a friction belt 4 made of synthetic resin or metal or a pair with a constant υ spacing (less than the diameter of the envelope O). It detects whether the installed cart 5 and the cart drive FR structure consisting of a υ cylinder 6, a pinion 7, and a rack 8 are placed on the cart 5 to move the cart 5 in the lateral direction. It consists of a package detection sensor 9, a belt fixing mechanism 11 for fixing the belt 3Oa to the fixing machine frame lυ, and other speed increasing mechanisms. Packaging body incision and removal 1i1112 cylindrical down-wrapping body 1'7) Packaging material-E held by a pair of υ grippers 13.13 that can move up and down and open and close, which grips the entire length of the upper side, and a large number of pairs of grippers 13. A package cutting mechanism 15 consisting of a cutter 14 that cuts a continuous cutting line over the entire length of the side υ transverse joint, and a pair of removal rolls 16 that removes the packaging material while wrapping the lower side of the cut package l.
16 and 10 removal rolls ft1t18 for rolling the contents from which the packaging material has been removed to the delivery device 17.

The delivery device 17 includes a rotary machine 19 for storing the contents from which the packaging materials have been removed by laying them down as a group so as not to dismantle them; a lowering mechanism 20 for lowering and tilting the starting end side of the rotary machine 19'7); It consists of rotating the rotary machine 19 90 times and delivering the contents to the ejector 1t21 for 1 ml of rotation $122. An inclined loaf conveyor 23 for discharging and mixing the contents delivered from the discharging device 21 and the delivery device 11117 to a seamer (not shown), and [JtM rope conveyor 2]
It is comprised of a drive mechanism 24 that drives 3.

The invention has the above configuration. First, when a cylindrical package l is transferred onto the cart 5 of the transfer Wc 112 by an appropriate method, the sensor 9 detects the package l, and the cylinder 6 is activated, and the truck 5 is moved leftward by the pinion 7 and rack 8 that are interlocked with this cylinder, and the υ package 1 on the truck 5 is also transferred to the left. At this time, since the belt 4 is fixed in a proper position to the fixing machine frame 1oTf, for example,
When the cart 5 strokes 350 blocks to the left, the belt 4, which is passed between the two pulleys 3:3', also rotates, and along with this, the package 1 is also stroked to the left, reaching a maximum of 83 cm.
The V cylinder 6V moves the package l with a small stroke to the next package incision and removal device 12.
It can be transferred at greatly increased speed. Package incision and removal device 11
When the package 1 is transferred to the package 17), the entire upper length of the package 17) is automatically held in a V-shaped manner by a large number of pairs of grippers 13.
Next, an incision is automatically made with a cutter 14 over the entire length of the beak on the upper side of the sandwiched packaging material. The packaging material is removed by rolling the F side of the cut package l with a pair of removal rolls 16. After the packaging material has been removed, the contents are as follows:
It is rolled to the delivery device 17 by the removal roll rolling mechanism 1stc. The contents delivered to the delivery equipment [117v] rotating gutter 19 are maintained in a cylindrical state without being dismantled by lowering the starting end side of the rotating machine 19 by the lowering mechanism 20.

In order to easily transfer the contents to the next discharge device 21, the rotating machine 19 is rotated 90 times by the rotating mechanism 22 VC of the rolling trough 19 in the Ij 21 in an inclined state. Finally, the ejection device 2
The contents delivered to the seamer 1 are discharged to the next seamer 1 process by the rope conveyor 23.

The present invention achieves the following unique effects through the above configuration.

0) Since the incision and removal mechanism for the package are integrated, there is no possibility of lid failure due to folding and opening of the package, which previously occurred during transfer to the flame removal process after the incision was completed. Qo) The transfer device that transfers the package to the incision and removal device uses a rack, pinion mechanism, and speed increasing mechanism that does not have a rotational drive device, so the package can be transferred the maximum distance with a small stroke and air cylinder, and the cylinder “Compared to the direct drive system, compressed air consumption can be halved and it is economical.

(c) By rolling the entire removal roll during the delivery and removal of the contents from the incision and removal clamp, the entire device can be made more compact, and the processing of bamboo can be made easier because the long package can be processed. 1
It is expected that the village capacity will improve.
