Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inspection device, and particularly to an inspection buffer device for a Matsushi production line. This issue also relates to line efficiency, since such inspection and dampening equipment is typically included in some lines.

In this line, individual filled matte boxes are inspected and then packed or otherwise further processed.

More precisely, the object of the invention is to provide a shock absorbing device that is fully automatic, compact, efficient, easy to maintain and relatively inexpensive;
The equipment was to be capable of inspecting products as well.

Moreover, the problem was to obtain a synchronized or uniform supply of two or several transport-passage passages within the damping device, especially at the discharge end of the damping device.

In the Matsushi production line, the aforementioned problem was solved by the combination of an inspection table and a semi-automatic damping device in the form of a conveyor with a storage for filled boxes. If synchronization or uniform feeding was required, it was also necessary to use a separate synchronization device in addition to the two devices described above.

However, this known solution is space-consuming, maintenance-intensive and human-intensive, and is therefore an expensive and insufficient solution to the above-mentioned problem.

In order to eliminate the above drawbacks and solve the problems,
The damping device is configured as a jet flow conveyor;
It is also proposed according to the invention that each input and output section is formed as an inspection location.

The jet flow conveyor is used on the Matsushi production line.
For example, match boxes that are transferred one after another from a box filling machine are temporarily stored for inspection and inspection.

Furthermore, the synchronization may be obtained by means of a synchronizing or feeding device operating individually in each individual transfer path of the jet stream conveyor, and said synchronizing or feeding device may be arranged between the jet stream conveyor and the discharge section. Proposed.

In a preferred embodiment, the synchronization or feeding device also acts as a box rotation device to allow inspection of the box from different sides and to place the box in the desired position for packaging or further processing. .

Further measures according to the invention are evident from the claims and will be illustrated in connection with the following description of exemplary embodiments of the device according to the invention.

However, already at this stage the present invention provides a compact, less human-intensive and fully automatic device with excellent inspection equipment, which also allows any printing on the boxes to be relatively arbitrary and furthermore It can be stated that only little maintenance is required.

Preferred embodiments of the invention will now be described with reference to the accompanying drawings.

In FIG. 1, a so-called jet flow conveyor 11 is shown supported by a stand 10. Stand 10 and inspection table 12 are supported on a substantially horizontal support 13. A jet flow conveyor is included in the match production line, and FIG. 3 shows how this conveyor is arranged within the line. A box filling machine is indicated by reference numeral 14, in which the matches are filled into inner boxes, which are then closed by outer boxes of conventional type. The embodiment shown includes two outlet passages 1 from the filling machine.
There are 5 and 16. In the inspection table 12, the two channels are transformed into a transfer chain, for example a plastic link chain 17,18. exit passage 15,
16 is a transfer chain 1 for transporting the matsuti boxes 19 transferred from the box filling machine 14 of the matsuti production line.
This is the passage to move to 7 and 18. During the transport of the box 19 in the passages 15, 16 and by the chains 17, 18,
The orientation of the individual boxes is as shown in the upper left part of FIG. 3, ie the boxes lie on their wide sides.

During the transport of the boxes by the chains 17, 18, the operator 19' performs an initial manual inspection of the boxes. Boxes that have too many matches are fixed, as are boxes that are not extruded correctly. Only completely defective boxes are excluded, i.e. table 12
through an opening (not shown). During this initial box check, the external dimensions of the box are checked before it reaches the jet stream conveyor 11 to ensure that no mistakes are made.

In the embodiment shown, the jet stream conveyors 17, 18 include two rows, ie, two different conveyor paths. An elevator 22 lifts the boxes through the two vertical sections 20, 21 of the jet stream conveyor 11 to an upper floor 23 of the conveyor. This upper floor 23 is the horizontal top portion of the jet flow conveyor 11. This jet stream conveyor is pneumatically driven in a manner known per se and, by means of the pneumatic cushioning principle, the boxes are transported downwards in the jet stream conveyor 11 through the usual floors so as to finally reach the vertical section 24. be done.

As shown in FIG. 4, the outlets of the vertical portions 24 are arranged horizontally offset from the centers 25 of individually supported rotating wheels 26 (one for each transfer path). The rotary wheel 26 therefore has a vertical portion 2
It will be rotated by the force of the box pushed out from 4. Each wheel 26 for each passage has a recess 27 around its periphery to support one box at a time. The recesses 27 each have an extension 28 which allows the rotating wheel 26 to rotate in the direction of the arrow 30 to move the matchbox 19 into the recess 2.
7 onto the sliding plate 29, it moves to the right in the figure and acts as a pushing finger to send it sequentially onto the belt conveyor 32. Rotating wheel 2
6, whose upper part is placed in a slot cut into the end of the sliding plate 29, because the side length of the matte box 19 supported by the recess 27 is longer than the axial width of the rotating ring 26. , both ends of the box protrude outside the rotating wheel.

Therefore, the match box 19 is transferred from the vertical section 24 to the belt conveyor 3 via the rotating wheel 26 and the sliding plate 29.
Sending to 2 is performed as follows.

One matchbox 19 pushed out from the outlet of the vertical portion 24 is placed in the recess 2 of the rotating wheel 26 directly below it.
7 and the extrusion force causes the rotary wheel 26 to rotate in the direction of arrow 30 (this rotation brings the next recess 27 directly below the vertical portion 24). Box 19 supported in recess 27
Since both end portions of the slider protrude to the sides of the rotating ring 27, as it rotates, they come into contact with both side portions of the slot of the sliding plate 29 that pinches the rotating wheel 26, and the extension portions (pushing fingers ) 28, the box 19 is moved over the slot from the recess 27 onto the sliding plate 29 and is pushed to the right in the figure. In this way, the boxes 19 are sent one after another from the vertical section 24 via the rotary wheel 26 onto the sliding plate 29, and are transferred onto the belt conveyor 32 while being pushed from behind.

At this time, the direction of the box 19 is rotated by 90 degrees compared to the direction on the first conveyor 17, 18 due to the action of the rotating wheel 26, and is independent of the speed of the box up to that point. synchronized and conveyed by a second conveyor 32. Second conveyor 32
extend parallel to the first conveyors 17, 18 and constitute a second inspection location for checking the matchboxes.
After the check, the boxes remain standing on their short sides and are transferred further to the packaging machine 33 in the illustrated embodiment.

As mentioned above, the top of the sliding plate 29 is completely filled with matching boxes 19 up to the second belt conveyor 32, and the boxes sent at different speeds to each passage of the jet flow conveyor 11 are completely filled with matching boxes 19 on the conveyor 32. are pushed out sequentially, regardless of the speed up to that point,
They are transported at intervals suitable for inspection determined by the speed of the conveyor 32.

Although specific embodiments of the invention have been described,
Obviously, other examples and variations are possible. For example, each jet stream may be fed into and discharged from the conveyor from directions other than those shown. The jet stream conveyor may further include any number of conveyors.
