Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for assembling and manufacturing a bottom cover of a cardboard case.

Conventional box making machines transport the cardboard case forward, stopping intermittently along the way, and each time the transport stops, a stopper is driven in with a boxer.

In this type of configuration, not only does the interlocking of the feeding device that feeds out the cardboard case become intermittent and complicated, but if the length of the cardboard case changes, the position of the boxer and the stop position of the cardboard case must be adjusted accordingly. This required adjustment.

This invention eliminates these drawbacks.

For this reason, the present invention provides a push-back device 3 that engages the cardboard case 1 at the front end of a feeding device 2 that engages the cardboard case 1 and feeds it to the front side, and pushes the cardboard case 1 back at a fixed interval to the rear side. At the same time, a stop is located on the bottom cover 4 of the cardboard case 1 when the cardboard case stops immediately after being fed out by the feeding device 2 and when the cardboard case 1 stops immediately after being pushed back by the push-back device 3. The box making machine is provided with a boxer 6 for driving in the box 5.

Embodiments of the present invention will be described below with reference to the drawings.

The feeding device 2 consists of attachments attached to a chain 8 stretched horizontally on an underframe 7, and one cardboard case 1 is fed out for each attachment.

A guide body 9, a rotating body 10, and a guide body 11, 11, which bend the bottom cover 4 from the front and back while guiding the cardboard case 1, are disposed above the feeding device 2.

The push-back device 3 has one attachment on a chain 12 which is located in front of the feeding device 2 and stretched over the underframe 7, and this chain 12 and the attachment are attached in a direction opposite to the chain 8 and the attachment. In order to rotate the chain 12, the length of the chain 12 is equal to the spacing between the attachments of the chain 8.
The chain 12 is in a constant interlocking relationship so that it rotates once for every one pitch rotation.

Boxer 6 is located above between chains 8 and 12 and is located above bottom cover 4.
On the side, the front and back fasteners 5 are opposed to each other so that they can be driven in at the same time, and on the top lid side, a receiver 13, which serves as the stand when driving in the fasteners 5 of this boxer 6, is mounted at a certain timing. It is a configuration that allows you to appear in.

Next, the operation of the above example will be explained.

The cardboard case 1 that is fed out by the feeding device 2 is raised from a flat folded state into a rectangular tube shape. It is guided and bent.

The cardboard case 1 is fed out to the boxer 6 position with the bottom cover 4 facing sideways, and is removed from the feeding device 2 and stopped.
Here, the receiving rod 13 is fitted into the cardboard case 1 to receive the inside of the bottom cover 4, and at the same time, the boxer 6 drives the fasteners 5 into two places at the front and back.

When the driving of the upper tool 5 is completed, the receiving rod 13 retracts slightly, and the force of the constantly rotating push-back device 3 pushes the cardboard case 1 back at an appropriate interval to stop it, and at this time, the second stopper 5
The implant is made in a different position than above.

The cardboard case 1 in which the stopper 5 has been driven in this way is successively pushed forward by the succeeding cardboard cases to complete the box manufacturing.

Since this invention has the above-mentioned configuration, the feeding device 2
It is simple because it can be configured to constantly rotate, and the push-back device 3 can also be simplified, and even if cardboard cases 1 of different lengths are supplied, the position where the stopper 5 is driven is fixed at a constant position from the front and rear ends. , and only the spacing in the center differs,
There is no need to adjust the movement of the driving position, etc., and a convenient and efficient box making machine is obtained.

[Brief explanation of drawings]

The drawings show one embodiment of the invention, with FIG. 1 being a side view and FIG. 2 being a plan view. In the figure, numeral 1 is a cardboard case, 2 is a feeding device, 3 is a push-back device, 4 is a bottom cover, 5 is a stopper, and 6 is a boxer.

Claims (1)

[Claims] 1. A push-back device is provided at the front end of the feeding device that engages the cardboard case and feeds it to the front side, and a push-back device that engages the cardboard case and pushes it back to the rear side at a fixed interval, and a On the other hand, a box making machine is provided with a boxer that is positioned to drive in a stopper when the cardboard case is stopped immediately after being fed by the feeding device and when the cardboard case is stopped immediately after being pushed back by the push-back device.
