JPS58216859A - Apparatus for automatically sticking tape - Google Patents

Abstract

PURPOSE:To prevent products from being damaged, by providing an automatic tape sticking apparatus wherein tapelike materials are simultaneously stuck on opposite surfaces of the products that are being delivered and the tapelike materials are cut into a prescribed length, which apparatus is characterized in that after the tapelike materials are stuck, the tapelike materials are cut at a position between the products with the tapelike material strained. CONSTITUTION:When the successive products P are fed along guides 1, 2 and between blocks 12, 14 of a first clamping mechanism 10, the tapelike materials T are led from storage rolls 3 to separator rollers 42 that release release papers (t) to become parallel with the products P. Then the tapelike materials T from which the release papers (t) have been released are stuck to the opposite surfaces of the products P by the action of the blocks 12, 14, and then are positively secured to the products P by the pressing action of a second clamp mechanism 20. When the boundary sections of the products P arrive at a position where a cutter 53 will act, a table 31 is moved to the right with the products P clamped by a third clamp mechanism 30 so that a gap is created between the products P, and then the cutter 53 is moved into the gap to cut the tapelike materials T.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic tape applicator, and more specifically, it applies tape-like materials simultaneously to opposing surfaces of products that are continuously supplied, and also applies tape-like materials to the opposite surfaces of products that are continuously supplied, and also applies tape-like materials according to the length of the products. It concerns an automatic device for cutting.

An example of the above-mentioned product is a chassis for supporting the keyboard of a keyboard instrument such as a piano, and a felt tape is attached to the front and back surfaces of the chassis to prevent unpleasant noises from occurring when the keyboard and chassis come into contact. has been done.

An example of a conventional method for attaching such a tape-like material to a product is to manually attach a tape-like material cut to the same length as the product to one side of the product, and then attach it to the other surface. Pasting is done in the same way. In another example, several products are assembled in succession in the longitudinal direction, and a tape-like material equal to the total length of the assembly is manually pasted on one side of the assembly. The tape-like material is cut using the same method, and the same manual operation is applied to other surfaces of the assembly.

In all cases where such conventional methods are used, the same pasting operation must be repeated for each side of the product. Also, since a release paper is attached to the tape-like material to protect the surface to which it is attached, it must be peeled off prior to attachment. In any case, since it is done manually, the pasting work is very complicated and time consuming, which is contrary to the efficient use of labor. In particular, when cutting a common tape-like material across the entire length of an aggregate consisting of several products, the edges of adjacent products are in contact, so care must be taken not to damage the product edges during cutting. This had to be done manually.

An object of the present invention is to completely automate and continuous the work of attaching a tape-like material to a product as described above.

That is, in the present invention, a plurality of products are continuously fed in the longitudinal direction along a predetermined straight guide path, and tape-like objects are transferred toward the guide path from both sides to prevent the products from being stuck. Before the meeting with the surface, the release paper is peeled off from both tape-like materials by a peeling mechanism attached to the surface, and the tape-like materials are continuously affixed to the surface to be adhered to the product being transferred, and are distributed along the above-mentioned guide path. The provided clamper mechanism group elastically presses the tape-like object against the product from both sides, and the boundary between the adjacent products comes between the Nth (N>1) and (N+1)th clamper mechanisms. At this timing, only the (N+1)th clamper mechanism is slightly moved downstream of the product transfer direction to form a gap at the boundary, and in this state, the cutter mechanism is advanced from at least one side to form a tape. It is something that cuts things.

The present invention will be explained in more detail below with reference to embodiments shown in the accompanying drawings.

In FIG. 1, the product P is continuous in the longitudinal direction (i.e., with the end surfaces in contact) along the guide path defined by the guide l.
It is transported and subjected to the action of the device of the present invention, and after the action is completed, it is sent out along the guide 2.

Along the above-mentioned conduit, three sets of clamping mechanisms 10, 20, 30 are provided in the illustrated example.

The first clamp mechanism 10 is for attaching a tape-like object,
The base 11 and the base 11 on one side of the product transfer path.
It has a movable block 12 installed above and movable in a direction perpendicular to the guideway, a fluid pressure cylinder 13 that drives the movable block 12, and a fixed block 14 fixed to the base 11 on the other side of the guideway. are doing.

The second clamp mechanism 20 elastically presses the tape-like material against the product P and cooperates with a third clamp mechanism 30 (described later) to help cut the tape-like material. A movable clamp 22 installed on the base 11 on one side and movable in a direction perpendicular to the conduit, a fluid pressure cylinder 23 for driving this movable clamp 22, and a hydraulic cylinder 23 fixed to the base 21 on the other side of the conduit. It has a fixed clamp 24.

The third clamp mechanism 30 is the second clamp mechanism 20 described above.
It cooperates with the base 31. to help cut the tape-like material, and similarly the base 31. Movable clamp 32. Although it has a hydraulic cylinder 33 and a fixed clamp 34, the base 31 is further configured to be movable on a support 35 in a direction parallel to the guide channel.

On the upstream side of the first clamp mechanism IO, a pair of tape-like material supply sources and a release paper peeling mechanism are provided on both sides of the guide path, but since their structure and arrangement are exactly the same, only one will be explained. do.

A tape-like material storage roll 3 is provided on the side of the product transfer channel, and the tape-like material T is then sent to the block 12-14 of the first clamping mechanism 10, where it is covered with the product P. Attach to the adhesive surface. The meeting state is shown in Figure 2.

The release paper peeling mechanism 40 is provided upstream of the storage roll 3 described above. The peeling mechanism 40 includes a base 41 and a separator roller 42 supported by the base 41 and rotatably provided near the upstream end of the block 12.14. A roller 43 is rotatably supported on the base 41. Further, an L-shaped bar 45 is loosely fitted at the top corner of a support shaft 44 fixed on the base 41, and a roller 46 is mounted on one limb of the support shaft 44 in opposition to the roller 43 described above.
is installed so that it can rotate freely. A compression spring 48 is interposed between the other limb of the lever 45 and an adjustment bolt 47 screwed into a bracket on the base 41.
The elastic force can be adjusted using the adjustment bolt 47. Further, the roller 43 is constantly rotated by an appropriate driving source (not shown), and the roller 46 whose circumferential surface is elastically pressed against it by the elastic force of a spring 48 to form a nip for the release paper is also rotated. It rotates with. It is desirable that the peripheral speed of rotation of the roller 43 is set to approximately twice the speed at which the product P is transported along the guide path. Roller 43.
The degree of slippage between the release paper t and the release paper t can be adjusted as appropriate using the adjustment bolt 47.

Second. A cutting mechanism 50 is provided at an intermediate position of the third clamping mechanism 20.30. That is, a disc-shaped cutter 53 is attached to the output shaft of a drive motor 52 provided on a base 51.
is fixed. Furthermore, the base 51 can be moved along the rails 54 in a direction perpendicular to the product transfer path. The radial direction of the cutter 53 is perpendicular to the guide path, and its position is made to coincide with the boundary between the preceding and following products P during the rest period during the intermittent transfer of the products.

The transfer of the product P along the guide path depends on the speed, but for safety reasons, it is preferable to carry out the cutting during the stationary period as intermittent transfer, and the distance per intermittent transfer is the length of the cutting mechanism 5.
It is preferable to set it equal to the length of the product P for consistency with the operation of 0.

Next, the effect will be explained.

The products P that are continuous back and forth are sequentially moved along the guide path defined by the guides 1 and 2 to the block 1 of the clamping mechanism 10.
Sent under the control of 2.14. In parallel with this, the tape-like material T from the storage roll 3 is transferred to the separator roller 4.
The release paper t that is guided to the roller 43 and peeled off here is
．． 46. And block 12.
The tape-like material T fed under the control of the second clamp mechanism 14 is stuck to both sides of the product P by these actions, and as the product P is further transferred, it is evenly and reliably placed on the product P by the suppressing action of the second clamp mechanism 20. Fixed. At the point in time when the boundary between the front and rear products P comes to a position where the boundary coincides with the radial direction of the cutter 53, the third clamp mechanism 30 closes the clamp 32.3.
4 continues to press the tape-like material T against the product P, the base 31 moves slightly toward the downstream side on the support 35 as shown by arrow A in FIG. Then, a small gap is formed between the products 2 in front and behind at the boundary, and the tape-like material T stretches in the direction of the guide path by that amount. In this state, when the base 51 of the cutting mechanism 50 moves in the direction of the arrow B, the cutter 53 cuts the tape-like material T. This cutting is performed very quickly and reliably since the tape-like material T is in a stretched state. The product P that has been cut is the third
The cutting mechanism 50 is released from the restraint of the clamp mechanism 30 and sent to the next process, and the cutting mechanism 50 returns to its original state and is ready for the next cycle of cutting.

According to this invention, when it becomes possible to automatically apply the tape-like material simultaneously and in parallel to both sides of the product, the release paper is also automatically peeled off from the tape-like material prior to adhesion.

Furthermore, since the cutting is performed while the tape-like material is under tension and by utilizing the gap between the product boundaries, the operation is quick and reliable, and there is no risk of damaging the product ends. Moreover, since the products are completely automatically processed while being transferred one after another, the processing efficiency is very high and it is labor-saving.
